                               PROSPECTUS SUMMARY
- ------------------------------------------------------------------------------
 
  THE FUND. Van Kampen American Capital Municipal Bond Fund (the "Fund") is a
diversified open-end management investment company organized as a Delaware
business trust.
 
  MINIMUM PURCHASE. $500 minimum initial investment and $25 minimum for each
subsequent investment (or less as described under "Purchase of Shares").
 
  INVESTMENT OBJECTIVE. Interest income exempt from federal income tax. There
is, however, no assurance that the Fund will be successful in achieving its
objective.
 
  INVESTMENT POLICY. Investing in a diversified portfolio of obligations issued
by states, territories or possessions of the United States and the District of
Columbia and their political subdivisions, agencies and instrumentalities, the
interest from which is exempt from federal income tax.
 
  INVESTMENT RESULTS. The investment results of the Fund during the past ten
years are shown in the table of "Financial Highlights."
 
  ALTERNATIVE SALES ARRANGEMENTS. The Fund offers three classes of shares to the
general public, each with its own sales charge structure: Class A shares, Class
B shares and Class C shares. Each class has distinct advantages and
disadvantages for different investors, and investors may choose the class of
shares that best suits their circumstances and objectives. See "Alternative
Sales Arrangements -- Factors for Consideration." Each class of shares
represents an interest in the same portfolio of investments of the Fund. The per
share dividends on Class B and Class C shares will be lower than the per share
dividends on Class A shares. See "Alternative Sales Arrangements." For
information on redeeming shares see "Redemption of Shares."
 
   
  Class A Shares. These shares are offered at net asset value per share plus a
maximum initial sales charge of 4.75% of the offering price. Investments of $1
million or more are not subject to any sales charge at the time of purchase, but
a contingent deferred sales charge of one percent may be imposed on certain
redemptions made within one year of purchase. The Fund pays an annual service
fee of up to 0.25% of its average daily net assets attributable to such class of
shares. See "Purchase of Shares -- Class A Shares" and "Distribution Plans."
    
 
   
  Class B Shares. These shares are offered at net asset value per share and are
subject to a maximum contingent deferred sales charge of four percent of
redemption proceeds during the first and second year, declining each year
thereafter to zero after the fifth year. See "Redemption of Shares." The Fund
pays a combined annual distribution fee and service fee of up to one percent of
its average daily net assets attributable to such class of shares. See "Purchase
of Shares -- Class B Shares" and "Distribution Plans." Class B shares will
convert automatically to Class A shares six years after the end of the calendar
month in which the
    
 
                                        3
<PAGE>   4
 
shareholder's order to purchase was accepted. See "Alternative Sales
Arrangements -- Conversion Feature."
 
  Class C Shares. These shares are offered at net asset value per share and are
subject to a contingent deferred sales charge of one percent on redemptions made
within one year of purchase. See "Redemption of Shares." The Fund pays a
combined annual distribution fee and service fee of up to one percent of its
average daily net assets attributable to such class of shares. See "Purchase of
Shares -- Class C Shares" and "Distribution Plans." Class C shares will convert
automatically to Class A shares ten years after the end of the calendar month in
which the shareholder's order to purchase was accepted. See "Alternative Sales
Arrangements -- Conversion Feature."
 
  DISTRIBUTIONS FROM THE FUND. Income dividends are distributed monthly. Any
taxable net realized capital gains are distributed annually. Such distributions
are automatically reinvested in shares of the Fund at net asset value per share
(without sales charge) unless payment in cash is requested. See "Shareholder
Services -- Reinvestment Plan" and "Distributions from the Fund."
 
  INVESTMENT ADVISER. Van Kampen American Capital Asset Management, Inc. (the
"Adviser") is the investment adviser to the Fund.
 
  DISTRIBUTOR. Van Kampen American Capital Distributors, Inc. (the
"Distributor").
 
   
  RISK FACTORS. The Fund invests primarily in long-term Municipal Bonds which
tend to produce higher yields and are subject to greater market fluctuations as
a result of changes in interest rates ("market risk") than Municipal Bonds with
shorter maturities and lower yields. Up to 20% of the Fund's total assets may be
invested in Municipal Bonds rated Ba or B by Moody's Investors Service
("Moody's") and BB or B by Standard & Poor's Corporation ("S&P"), or which, if
non-rated, are in the opinion of the Adviser of comparable quality. Lower rated
securities are subject to market risks and are also subject to the ability of
the issuer to meet its principal and interest obligations ("credit risk").
Municipal Bonds rated B by Moody's are considered generally to lack
characteristics of the desirable investment in that assurance of interest and
principal payments or maintenance of other terms of the contract over any long
period of time may be small. The Fund may seek to hedge interest rate risk
through transactions in futures contracts and related options. Any net gains
from futures and options transactions are subject to federal income tax and such
transactions involve certain risks. See "Investment Practices -- Futures
Contracts and Related Options." The Fund invests a portion of its assets in
private-activity bonds so that a portion of its exempt-interest dividends
constitutes an item of tax preference to the extent such dividends represent
interest received from these private-activity bonds. See "Distributions from the
Fund" and "Tax Status."

information appearing elsewhere in this Prospectus.
 
- ------------------------------------------------------------------------------
PROPOSED REORGANIZATION
- ------------------------------------------------------------------------------
 
  On May 11, 1994, the Board of Directors of the Fund approved an Agreement and
Plan of Reorganization between the Fund and the Van Kampen Merritt Municipal
Income Fund, a sub-trust of the Van Kampen Merritt Tax Free Fund (the "Van
Kampen Fund"), a fund advised by Van Kampen American Capital Investment Advisory
Corp., providing for the transfer of assets and liabilities of the Fund to the
Van Kampen Fund in exchange for shares of beneficial interest of the Van Kampen
Fund at its net asset value per share (the "Reorganization").
 
  Van Kampen American Capital Investment Advisory Corp. and the Adviser are
wholly owned subsidiaries of Van Kampen American Capital, Inc., which is a
wholly owned subsidiary of VK/AC Holding, Inc.
 
  The Reorganization is subject to approval by the holders of a majority of the
outstanding shares of the Fund. Further details of the proposed Reorganization
will be contained in the proxy statement/prospectus expected to be mailed to
shareholders in August, 1995.
 
   
  The Van Kampen Fund had assets of $691.9 million on March 31, 1995. Its
objective is to seek to provide high current income exempt from federal income
tax consistent with preservation of capital 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. The Fund and the Van Kampen Fund
have similar investment objectives and follow generally similar investment
policies although the Van Kampen Fund has greater flexibility to invest in
municipal bonds rated below A by Moody's and S&P. In addition, the Van Kampen
Fund has greater flexibility to utilize options and futures, as well as interest
rate transactions such as swaps, caps, floors or collars. The Van Kampen Fund
may invest a substantial portion of its assets in municipal securities that pay
interest that is subject to the federal alternative minimum tax, while the Fund
may only invest up to 20% of its assets in such securities.
    
 
  The Fund will continue its normal operations prior to the Reorganization.

* Based on conversion to Class A shares after six years.
 
  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 "Example" reflects expenses based on the "Annual Fund
Operating Expenses" table as shown above carried out to future years and are
included to provide a means for the investor to compare expense levels of funds
with different fee structures over varying investment periods. To facilitate
such comparison, all funds are required to utilize a five percent annual return
assumption. 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 LESS THAN THOSE SHOWN. For a more complete
description of such costs and expenses, see "Purchase of Shares," "Investment
Advisory Services" and "Redemption of Shares."

THE FUND
- ------------------------------------------------------------------------------
 
  The Fund is an open-end, diversified management investment company. This type
of company is commonly known as a mutual fund. A mutual fund provides, for those
who have similar investment goals, a practical and convenient way to invest in a
diversified portfolio of securities by combining their resources in an effort to
achieve such goals.
 
  Fourteen Trustees have the responsibility for overseeing the affairs of the
Fund. The Adviser, 2800 Post Oak Boulevard, Houston, Texas 77056, determines the
investment of the Fund's assets, provides administrative services and manages
the Fund's business and affairs. The Adviser together with its predecessors, has
been in the investment advisory business since 1926.
 
   
- ------------------------------------------------------------------------------
    
INVESTMENT OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------
 
  The Fund's objective is to provide as high a level of current interest income
exempt from federal income tax as is consistent with the preservation of
capital. This limitation could result in a lesser level of interest income than
that of funds willing to incur greater risk of capital. Because the value of and
yield on Municipal Bonds fluctuate, there can be no assurance that the Fund's
objective will be achieved.
 
  The Fund seeks to achieve its objective by investing in a diversified
portfolio of obligations issued by or on behalf of states, territories or
possessions of the United States and the District of Columbia and their
political subdivisions, agencies and instrumentalities, the interest from which,
in the opinion of bond counsel for the issuer, is exempt from federal income
tax. See "Municipal Bonds." Under normal circumstances, at least 80% of the
assets of the Fund are invested in Municipal Bonds which are exempt from federal
income tax. This is a fundamental policy and may not be changed without the
approval of at least a majority of the outstanding shares of the Fund. The Fund
does not independently evaluate the tax-exempt status of the Municipal Bonds in
which it invests. The Fund invests principally in Municipal Bonds rated at the
time of purchase within the four highest grades assigned by Moody's or S&P, or
which, if non-rated, is in the Adviser's opinion of comparable quality. The Fund
may not acquire any Municipal Bond which is rated below A by Moody's and S&P or
which is non-rated if immediately after and as a result of such purchase such
Bonds would constitute more than 50% of the Fund's total assets. The Fund may
not acquire any Municipal Bond which is rated below Baa by Moody's and below BBB
by S&P, or which, if non-rated, is in the opinion of the Adviser of comparable
quality, if immediately after and as a result of such purchase such Bonds would
constitute more than 20% of the Fund's total assets. The Fund may not, however,
purchase any Municipal Bond rated below B by
 
                                       11
<PAGE>   12
 
Moody's and S&P or any non-rated Municipal Bond considered by the Adviser to be
of comparable quality. Ratings at the time of purchase determine which
securities may be acquired, and a subsequent reduction in rating does not
require the Fund to dispose of a security. Because investment in lower-rated
securities involves greater investment risks, achievement of the Fund's
investment objectives may be more dependent on the Adviser's credit analysis
than would be the case if the Fund invested only in higher-rated securities.
Non-rated Municipal Bonds are not necessarily of lower quality than rated
Municipal Bonds, but the market for rated Municipal Bonds is often broader. The
Fund may seek to hedge against changes in interest rates through transactions in
listed futures contracts related to U.S. Government securities or based upon the
Bond Buyers Municipal Bond Index and options thereon. See "Investment
Practices -- Futures Contracts and Related Options."
 
  During the fiscal year ended September 30, 1994, the average percentage of the
Fund's assets invested in Municipal Bonds within the various rating categories
(based on the higher of the S&P or Moody's ratings), and the non-rated debt
securities, determined on a dollar weighted average, were as follows:
 
<TABLE>
    <S>                                                    <C>
    AAA/Aaa.............................................     20.98%
    AA/Aa...............................................     16.74%
    A/A.................................................     28.99%
    BBB/Baa.............................................     11.13%
    BB/Ba...............................................      1.16%
    CCC/Caa.............................................       .63%
    *Non-rated..........................................     14.37%
    Other net assets....................................      6.00%

        Total net assets................................       100%
</TABLE>
 
- ---------------
 
* The non-rated debt securities as a percentage of total net assets were
  considered by the Adviser to be comparable to securities rated by Moody's as
  follows: AAA - .17%, BBB - 10.08%, BB - 3.68% and B - .44%.
 
  Variations in the quality and maturity of the Fund's portfolio investments can
be expected to affect the Fund's yield and the degree of market and credit risk
to which the Fund is subject. Municipal Bonds rated BBB by S&P or Baa by Moody's
may have speculative characteristics so that changes in economic conditions or
other circumstances are more likely to lead to a weakened capacity to make
principal and interest payments than in the case of higher grade Municipal
Bonds. The Fund maintains the flexibility to invest up to 20% of its total
assets in Municipal Bonds rated Ba or B by Moody's or BB or B by S&P. Municipal
Bonds rated Ba by Moody's are judged to have speculative elements so that their
future cannot be considered as well assured. Municipal Bonds rated B by Moody's
are considered generally to lack characteristics of a desirable investment in
that assurance of interest and principal payments or maintenance of other terms
of the contract over any long period of time may be small. Additional risks of
investing in
 
                                       12
<PAGE>   13
 
lower-rated Municipal Bonds are described in the Statement of Additional
Information which includes an appendix describing Municipal Bond ratings.
Generally, Municipal Bonds with longer maturities tend to produce higher yields
and are subject to greater market fluctuations as a result of changes in
interest rates than Municipal Bonds with shorter maturities and lower yields.
The market value of Municipal Bonds generally rises when interest rates decline
and falls when interest rates rise. Generally, lower-rated Municipal Bonds
provide a higher yield than higher-rated Municipal Bonds of similar maturity but
are subject to greater credit risk. The Fund is not limited as to the maturities
of the Municipal Bonds in which it invests. Such securities may have remaining
maturities of up to 30 years or more. The average maturity, which may vary from
time to time, of the Municipal Bonds owned by the Fund on September 30, 1994,
was 20.32 years.
 
  On a temporary defensive basis, due to market conditions or pending investment
in Municipal Bonds, the Fund may hold temporary investments ("Temporary
Investments") consisting of short term municipal notes rated MIG 1 through MIG 4
by Moody's or SP-1 or SP-2 by S&P; variable rate demand notes rated VMIG 1 or
VMIG 2; tax-exempt commercial paper rated P-1 or P-2 in the case of Moody's or
A-1 or A-2 by S&P; securities issued or guaranteed by the U.S. Government, its
agencies or instrumentalities; certificates of deposit of domestic banks with
assets of $500 million or more and having deposits insured by the Federal
Deposit Insurance Corporation; and shares of tax-exempt money market investment
companies. See "Investment Practices -- Money Market Investment Companies."
 
  Temporary Investments may also include repurchase agreements collateralized by
Municipal Bonds or by any of the Temporary Investments described above,
provided, however, that no more than 15% of the Fund's net assets at the time of
purchase may be invested in repurchase agreements which do not mature within
seven days. Interest income from certain Temporary Investments may be taxable to
shareholders as ordinary income. See "Distributions from the Fund" and "Tax
Status". The Fund generally invests at least 90% of its assets in securities,
the income from which is exempt from regular federal income tax and at least 80%
of its assets in securities, the income from which is exempt from both such tax
and the federal alternative minimum tax. As a temporary defensive measure during
times of adverse market conditions, up to 50% of the Fund's assets may be
invested in such Temporary Investments.
 
  The Fund may invest up to 15% of its net assets in illiquid securities which
include Municipal Bonds issued in limited placements under which the Fund
represents that it is purchasing for investment purposes only, repurchase
agreements maturing in more than seven days and other securities subject to
legal or contractual restrictions on resale. Municipal Bonds acquired in limited
placements generally may be resold only in a privately negotiated transaction to
one or more other institutional investors. Such limitation could result in the
Fund's inability to realize
 
                                       13
<PAGE>   14
 
   
a favorable price upon disposition, and in some cases might make disposition of
such securities at the time desired by the Fund impossible. The 15% limitation
applies at the time the purchase commitment is made. See "Investment Practices
 -- Repurchase Agreements." Although the Fund may invest up to 15% of its net
assets in securities subject to restrictions on resale or for which there is no
readily available market, the Fund shall not invest in such securities in excess
of ten percent of its net assets without prior approval of the Trustees.
    
 
- ------------------------------------------------------------------------------
MUNICIPAL BONDS
- ------------------------------------------------------------------------------
 
  Municipal Bonds include debt obligations of a state, territory or a possession
of the United States and the District of Columbia and their political
subdivisions, agencies and instrumentalities, issued to obtain funds for various
public purposes, including the construction of a wide range of public facilities
such as airports, highways, bridges, schools, hospitals, housing, mass
transportation, streets and water and sewer works. Other public purposes for
which Municipal Bonds may be issued include refunding outstanding obligations,
obtaining funds for general operating expenses and obtaining funds to lend to
other public institutions and facilities. Certain types of Municipal Bonds are
issued to obtain funding for privately operated facilities.
 
  Many new issues of Municipal Bonds are sold on a "when-issued" basis. While
the Fund has ownership rights to the Bonds, the Fund does not have to pay for
them until they are delivered, normally 15 to 45 days later. To meet that
payment obligation, the Fund sets aside with the custodian sufficient cash or
securities equal to the amount that will be due. See "Investment
Practices -- Delayed Delivery and When-Issued Securities."
 
  The yields of Municipal Bonds depend on, among other things, general money
market conditions, general conditions of the Municipal Bond market, size of a
particular offering, the maturity of the obligation and rating of the issue. The
ratings of Moody's and S&P represent their opinions of the quality of the
Municipal Bonds they undertake to rate. It should be emphasized, however, that
ratings are general and are not absolute standards of quality. Consequently,
Municipal Bonds with the same maturity, coupon and rating may have different
yields while Municipal Bonds of the same maturity and coupon with different
ratings may have the same yield. A description of the ratings is included in the
Statement of Additional Information.
 
  Among the various types of Municipal Bonds are general obligation bonds,
revenue or special obligation bonds, industrial development bonds, pollution
control bonds, variable rate demand notes, and short-term tax-exempt municipal
obligations such as tax anticipation notes.
 
                                       14
<PAGE>   15
 
  General obligation bonds are backed by the taxing power of the issuing
municipality. Revenue bonds are backed by the revenues of a project or facility
- -- tolls from a toll-bridge, for example. Industrial development revenue bonds
are a specific type of revenue bond backed by the credit and security of a
private user. The Fund's ability to achieve its objective depends to a great
extent on the ability of these various issuers to meet their scheduled payments
of principal and interest.
 
  The Fund considers investments in tax-exempt Municipal Bonds not to be subject
to concentration policies and may invest a relatively high percentage of its
assets in Municipal Bonds issued by entities having similar characteristics. The
issuers may be located in the same geographic area or may pay their interest
obligations from revenue of similar projects such as hospitals, utility systems
and housing finance agencies. This may make the Fund's investments more
susceptible to similar economic, political or regulatory occurrences. As the
similarity in issuers increases, the potential for fluctuation in the Fund's per
share net asset value also increases. The Fund may invest more than 25% of its
total assets in industrial development revenue bonds, but it does not intend to
invest more than 25% of its assets in industrial development revenue bonds
issued for companies in the same industry or state. Sizeable investments in such
obligations could involve an increased risk to the Fund should any of such
issuers of any such related projects or facilities experience financial
difficulties.
 
  From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on Municipal Bonds. It may be expected that similar proposals may be
introduced in the future. If any such proposals were to be enacted, the ability
of the Fund to pay "exempt-interest" dividends may be adversely affected and the
Fund would re-evaluate its investment objective and policies and consider
changes in its structure.
 
- ------------------------------------------------------------------------------
INVESTMENT PRACTICES
- ------------------------------------------------------------------------------
 
  REPURCHASE AGREEMENTS. The Fund may enter into repurchase agreements with
domestic banks or broker-dealers in order to earn a return on temporarily
available cash. A repurchase agreement is a short-term investment in which the
purchaser (i.e., the Fund) acquires ownership of a debt security and that seller
agrees to repurchase the obligation at a future time and set price, thereby
determining the yield during the holding period. Repurchase agreements involve
certain risks in the event of default by the other party. In the event of the
bankruptcy of the seller of a repurchase agreement, the Fund could experience
delays in liquidating the underlying securities, and the Fund could incur a loss
if the value of the underlying securities declines. The Fund will not invest in
repurchase agreements maturing in more than seven days if any such investment,
together with any other illiquid
 
                                       15
<PAGE>   16
 
securities held by the Fund, exceeds 15% of the value of its net assets. In the
event of the bankruptcy or other default of a seller of a repurchase agreement,
the Fund could experience both delays in liquidating the underlying securities
and loss including: (a) possible decline in the value of the underlying security
during the period while the Fund seeks to enforce its rights thereto, (b)
possible lack of access to income on the underlying security during this period,
and (c) expenses of enforcing its rights.
 
  For the purpose of investing in repurchase agreements, the Adviser may
aggregate the cash that substantially all of the funds advised or subadvised by
the Adviser would otherwise invest separately into a joint account. The cash in
the joint account is then invested and the funds that contributed to the joint
account share pro rata in the net revenue generated. The Adviser believes that
the joint account produces greater efficiencies and economies of scale that may
contribute to reduced transaction costs, higher returns, higher quality
investments and greater diversity of investments for the Fund than would be
available to the Fund investing separately. The manner in which the joint
account is managed is subject to conditions set forth in the SEC order obtained
by the Fund authorizing this practice, which conditions are designed to ensure
the fair administration of the joint account and to protect the amounts in that
account.
 
  VARIABLE RATE DEMAND NOTES. Variable rate demand notes ("VRDNs") are tax-
exempt obligations which contain a floating or variable interest rate adjustment
formula and which are subject to an unconditional right of demand to receive
payment of the principal balance plus accrued interest either at any time or at
specified intervals not exceeding one year and in either case upon no more than
seven days notice. The interest rates are adjustable at intervals ranging from
daily ("floating rate") to up to one year to some prevailing market rate for
similar investments, such adjustment formula being calculated to maintain the
market value of the VRDN at approximately the par value of the VRDN upon the
adjustment date. The adjustments are typically based upon the prime rate of a
bank or some other appropriate interest rate adjustment index.
 
  The Fund may also invest in VRDNs in the form of participation interests
("Participating VRDNs") in variable rate tax-exempt obligations held by a
financial institution, typically a commercial bank ("institution").
Participating VRDNs provide the Fund with a specified undivided interest (up to
100%) in the underlying obligation and the right to demand payment of the unpaid
principal balance plus accrued interest on the Participating VRDNs from the
institution upon a specified number of days' notice, not to exceed seven days.
The Fund has an undivided interest in the underlying obligation and thus
participates on the same basis as the institution in such obligation except that
the institution typically retains fees out of the interest paid on the
obligation for servicing the obligation and issuing the repurchase commitment.
 
                                       16
<PAGE>   17
 
  STAND-BY COMMITMENTS. The Fund may acquire "stand-by commitments" with respect
to Municipal Securities held by it. Under a "stand-by commitment," a bank or
dealer from which Municipal Securities are acquired agrees to purchase from the
Fund, at the Fund's option, the Municipal Securities at a specified price. Such
commitments are sometimes called "liquidity puts."
 
  The amount payable to the Fund upon its exercise of a "stand-by commitment" is
normally (i) the Fund's acquisition cost of the Municipal Securities (excluding
any accrued interest which the Fund paid on their acquisition), less any
amortized market premium or plus any amortized market or original issue discount
during the period the Fund owned the securities, plus (ii) all interest accrued
on the securities since the last interest payment date during that period.
"Stand-by commitments" generally can be acquired when the remaining maturity of
the underlying Municipal Securities is not greater than one year, and are
exercisable by the Fund at any time before the maturity of such obligations.
 
  The Fund's right to exercise "stand-by commitments" is unconditional and
unqualified. A "stand-by commitment" generally is not transferable by the Fund,
although the Fund can sell the underlying Municipal Securities to a third party
at any time.
 
  The Fund expects that "stand-by commitments" will generally be available
without the payment of any direct or indirect consideration. However, if
necessary or advisable, the Fund may pay for a "stand-by commitment" either
separately in cash or by paying a higher price for portfolio securities which
are acquired subject to the commitment (thus reducing the yield-to-maturity
otherwise available for the same securities). The total amount paid in either
manner for outstanding "stand-by commitments" held in the Fund will not exceed
one half of one percent of the value of the Fund's total assets calculated
immediately after each "stand-by commitment" is acquired. The Fund intends to
enter into "stand-by commitments" only with banks and dealers which, in the
Adviser's opinion, present minimal credit risks.
 
  The Fund would acquire "stand-by commitments" solely to facilitate portfolio
liquidity and does not intend to exercise its rights thereunder for trading
purposes. The acquisition of a "stand-by commitment" would not affect the
valuation of the underlying Municipal Securities which would continue to be
valued in accordance with the method of valuation employed for the Fund in which
they are held. "Stand-by commitments" acquired by the Fund would be valued at
zero in determining net asset value. Where the Fund paid any consideration
directly or indirectly for a "stand-by commitment," its costs would be reflected
as unrealized depreciation for the period during which the commitment was held
by the Fund.
 
  DELAYED DELIVERY AND WHEN-ISSUED SECURITIES. Municipal Bonds may at times be
purchased or sold on a delayed delivery or a when-issued basis. These
transactions arise when securities are purchased or sold by the Fund with
payment and
 
                                       17
<PAGE>   18
 
delivery taking place in the future, often a month or more after the purchase.
The payment obligation and the interest rate are each fixed at the time the Fund
enters into the commitment. The Fund will only make commitments to purchase such
securities with the intention of actually acquiring the securities, but the Fund
may sell these securities prior to settlement date if it is deemed advisable.
Purchasing Municipal Bonds on a when-issued basis involves the risk that the
yield available in the market when the delivery takes place may actually be
higher than those obtained in the transaction itself; if yields so increase, the
value of the when-issued obligation will generally decrease. The Fund will
maintain a separate account at its custodian bank consisting of cash or liquid
high-grade debt obligations (valued on a daily basis) equal at all times to the
amount of any when-issued commitment.
 
   
  MONEY MARKET INVESTMENT COMPANIES. The Fund may invest in shares of open-end
investment companies which are tax-exempt money market funds. Such investment
would not exceed three percent of the total outstanding voting stock of the
acquired company; five percent of the value of the total assets of the Fund; or
ten percent of the total assets of the acquired company as held by the Fund and
all Van Kampen American Capital funds. When the Fund invests in a tax-exempt
money market fund, the Adviser will reduce its advisory fee by the amount of any
investment advisory and administrative services fees paid to the investment
adviser of the money market fund.
    
 
  FUTURES CONTRACTS AND RELATED OPTIONS. The investment policies of the Fund
permit the Fund to engage in transactions in listed futures contracts and
related options. Such transactions may be in listed futures contracts based upon
The Bond Buyer Municipal Bond Index (the "Index"), a price weighted measure of
the market value of 40 large-sized, recent issues of tax-exempt bonds or in
listed contracts based on U.S. Government securities.
 
  Futures contracts and options thereon may be used for defensive hedging or
anticipatory hedging purposes, depending upon the composition of the Fund's
portfolio and the Adviser's expectations concerning the securities markets. See
the Statement of Additional Information for discussion of futures contracts and
related options.
 
  Potential Risks of Futures Contracts and Related Options. The purchase and
sale of futures contracts and related options involve risks different from those
involved with direct investments in securities. While utilization of futures
contracts and related options may be advantageous to the Fund, if the Adviser is
not successful in employing such instruments in managing the Fund's investments,
the Fund's performance will be worse than if the Fund did not make such
investments. In addition, the Fund would pay commissions and other costs in
connection with such investments, which may increase the Fund's expenses and
reduce its return. The Fund may not purchase or sell futures contracts or
related options for which the aggregate initial margin and premiums exceed five
percent of the fair market value
 
                                       18
<PAGE>   19
 
of the Fund's assets. In order to prevent leverage in connection with the
purchase of futures contracts or call options thereon by the Fund, an amount of
cash, cash equivalent or liquid high-grade debt securities equal to the market
value of the obligation under the futures contracts or options (less any related
margin deposits) will be maintained in a segregated account with the custodian.
 
  PORTFOLIO TURNOVER. The Fund may purchase or sell securities without regard to
the length of time the security has been held to take advantage of short-term
differentials in bond yields consistent with its objective of seeking tax-exempt
interest income. The Fund engages in short-term trading only if the anticipated
benefits are expected by the Adviser to exceed the transaction costs. The Fund's
annual portfolio turnover rate is shown in the "Financial Highlights" table
shown herein. Since portfolio changes are made in light of market and other
conditions, the turnover rate may vary greatly from year to year. A 100%
turnover rate would occur, for example, if all the securities in the Fund's
portfolio were replaced once a year. A 100% turnover rate is substantially
greater than that of many other investment companies. Higher portfolio turnover
involves higher transaction costs and may result in realization of short-term
capital gains if securities are held for one year or less. Such gains are
taxable to shareholders as ordinary income except to the extent such gains are
offset by capital losses.
 
   
  PORTFOLIO TRANSACTIONS AND BROKERAGE PRACTICES. The Adviser is responsible for
the placement of orders for the purchase and sale of portfolio securities for
the Fund and the negotiation of the price of such transactions. The Municipal
Bonds in which the Fund invests are traded in the over-the-counter market.
Municipal Bonds are generally traded on a net basis and do not normally involve
any brokerage commissions. The cost of portfolio securities transactions of the
Fund primarily consists of dealer or underwriter spreads. The Adviser is
authorized to place portfolio transactions with brokerage firms participating in
the distribution of shares of the Fund and other Van Kampen American Capital
mutual funds if it reasonably believes that the quality of the execution and the
commission are comparable to that available from other qualified firms. The
Adviser is authorized to place portfolio transactions with brokerage firms that
provide it with investment and research information and to pay higher than the
lowest available commission if the Adviser determines that the cost is
reasonable in relation to the overall services provided. The information
received may be used by the Adviser in managing the assets of other advisory
accounts as well as in the management of the assets of the Fund.
    
 
  INVESTMENT RESTRICTIONS. The Fund has adopted certain investment restrictions
which, like the investment objective, may not be changed without approval by a
 
                                       19
<PAGE>   20
 
majority (as defined in the 1940 Act) vote of the Fund's shareholders. These
restrictions provide, among other things, that the Fund may not:
 
  1. Invest in securities other than Municipal Bonds and Temporary Investments
     (as defined herein), listed futures contracts related to U.S. Government
     securities, Municipal Bonds or to an index of Municipal Bonds, and options
     on such contracts.
 
  2. Invest more than five percent of its total assets at market value at the
     time of purchase in the securities of any one issuer (other than
     obligations of the United States Government or of any instrumentalities
     thereof).
 
  3. Borrow money, except from banks for temporary or emergency purposes, such
     borrowing not to exceed five percent of its total assets at market value at
     the time of borrowing. Any such borrowing may be secured provided that not
     more than ten percent of the total assets at market value at the time of
     pledging may be used as security for such borrowings. Notwithstanding the
     foregoing, the Fund may engage in transactions in options, futures
     contracts and related options, segregate or deposit assets to cover or
     secure options written, and make margin deposits and payments in connection
     with futures contracts and related options.
 
  4. Purchase any Municipal Bond rated below Baa by Moody's and below BBB by
     S&P, or which, if non-rated, is in the opinion of the Adviser of comparable
     quality, if immediately after and as a result of such purchase such Bonds
     would constitute more than 20% of the Fund's total assets.
 
  5. Purchase any Municipal Bond rated below A by Moody's and S&P, or which is
     non-rated, if immediately after and as a result of such purchase such Bonds
     would constitute more than 50% of the Fund's total assets.
 
  6. Purchase any Municipal Bond rated below B by Moody's and S&P or any
     non-rated Municipal Bonds considered by the Adviser to be of comparable
     quality.
 
  Each state and each political subdivision, agency or instrumentality of such
state, and each multi-state agency of which a state is a member is a separate
"issuer" as that term is used in this Prospectus. The non-government user of
facilities financed by industrial development bonds is also considered as a
separate issuer. If, however, a security is guaranteed by another entity,
securities issued or guaranteed by such guaranteeing entity shall be limited to
ten percent of the value of the Fund's total assets.

ratios are shown under the caption "Annual Fund Operating Expenses and Example"
herein.
 
   
  From time to time as the Adviser and/or the Distributor may deem appropriate,
they may voluntarily undertake to reduce the Fund's expenses by reducing the
fees payable to them to the extent of, or bearing expenses in excess of, such
limitations as they may establish.

- ------------------------------------------------------------------------------
ALTERNATIVE SALES ARRANGEMENTS
- ------------------------------------------------------------------------------
 
  The Alternative Sales Arrangements permits an investor to choose the method of
purchasing shares that is most beneficial given the amount of the purchase and
the length of time the investor expects to hold the shares.
 
  CLASS A SHARES. Class A shares are sold at net asset value plus an initial
maximum sales charge of up to 4.75% of the offering price. Investments of $1
million or more are not subject to any sales charge at the time of purchase, but
a contingent deferred sales charge of one percent may be imposed on certain
redemptions made within one year of the purchase. Class A shares are subject to
an ongoing service fee at an annual rate of up to 0.25% of the Fund's aggregate
average daily net assets attributable to the Class A shares. Certain purchases
of Class A shares qualify for reduced initial sales charges. See "Purchase of
Shares -- Class A Shares."
 
  CLASS B SHARES. Class B shares are sold at net asset value and are subject to
a deferred sales charge if they are redeemed within five years of purchase.
Class B shares are subject to an ongoing service fee at an annual rate of up to
0.25% of the Fund's aggregate average daily net assets attributable to the Class
B shares and an
 
                                       22
<PAGE>   23
 
ongoing distribution fee at an annual rate of up to 0.75% of the Fund's
aggregate average daily net assets attributable to the Class B shares. Class B
shares enjoy the benefit of permitting all of the investor's dollars to work
from the time the investment is made. The ongoing distribution fee paid by Class
B shares will cause such shares to have a higher expense ratio and to pay lower
dividends than those related to Class A shares. See "Purchase of Shares -- Class
B Shares." Class B shares will automatically convert to Class A shares six years
after the end of the calendar month in which the shareholder's order to purchase
was accepted. See "Conversion Feature" herein for discussion on applicability of
the conversion feature to Class B shares.
 
  CLASS C SHARES. Class C shares are sold at net asset value and are subject to
a deferred sales charge if redeemed within one year of purchase. Class C shares
are subject to an ongoing service fee at an annual rate of up to 0.25% of the
Fund's aggregate average daily net assets attributable to the Class C shares and
an ongoing distribution fee at an annual rate of up to 0.75% of the Fund's
aggregate average daily net assets attributable to the Class C shares. Class C
shares enjoy the benefit of permitting all of the investor's dollars to work
from the time the investment is made. The ongoing distribution fee paid by Class
C shares will cause such shares to have a higher expense ratio and to pay lower
dividends than those related to Class A shares. See "Purchase of Shares -- Class
C Shares." Class C shares will convert automatically to Class A shares ten years
after the end of the calendar month in which the shareholder's order to purchase
was accepted. See "Conversion Feature" herein for discussion on applicability of
the conversion feature to Class C shares.
 
  CONVERSION FEATURE. Class B shares and Class C shares will automatically
convert to Class A shares six years or ten years, respectively, after the end of
the calendar month in which the shares were purchased and will no longer be
subject to the distribution fee. Such conversion will be on the basis of the
relative net asset values per share, without the imposition of any sales load,
fee or other charge. The purpose of the conversion feature is to relieve the
holders of the Class B shares and Class C shares that have been outstanding for
a period of time sufficient for the Distributor to have been substantially
compensated for distribution expenses related to the Class B shares or Class C
shares as the case may be, from the burden of the ongoing distribution fee.
 
  For purposes of conversion to Class A, shares purchased through the
reinvestment of dividends and distributions paid on Class B shares and Class C
shares in a shareholder's Fund account will be considered to be held in a
separate sub-account. Each time any Class B shares or Class C shares in the
shareholder's Fund account (other than those in the sub-account) convert to
Class A, an equal pro rata portion of the Class B shares or Class C shares in
the sub-account will also convert to Class A.
 
                                       23
<PAGE>   24
 
   
  The conversion of Class B shares and Class C 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 distribution fee and higher transfer agency costs
with respect to Class B shares and Class C shares does not result in the Fund's
dividends or distributions constituting "preferential dividends" under the
Internal Revenue Code of 1986, as amended (the "Code"), and (ii) the conversion
of shares does not constitute a taxable event under federal income tax law. The
conversion of Class B shares and Class C shares may be suspended if such an
opinion is no longer available. In that event, no further conversions of Class B
shares or Class C shares would occur, and shares might continue to be subject to
the distribution fee for an indefinite period which may extend beyond the period
ending six years or ten years, respectively, after the end of the calendar month
in which the shareholder's order to purchase was accepted.
    
 
  FACTORS FOR CONSIDERATION. In deciding which class of shares to purchase,
investors should take into consideration their investment goals, present and
anticipated purchase amounts, time horizons and temperaments. Investors should
consider whether, during the anticipated life of their investment in the Fund,
the accumulated distribution fees and contingent deferred sales charges on Class
B shares or Class C shares prior to conversion would be less than the initial
sales charge on Class A shares purchased at the same time, and to what extent
such differential would be offset by the higher dividends per share of Class A
shares. 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. In this regard, Class A shares may
be more beneficial to the investor who qualifies for reduced initial sales
charges or purchases at net asset value, as described herein under "Purchase of
Shares -- Class A Shares." For these reasons, the Distributor will reject any
order of more than $500,000 for Class B shares or any order of more than $1
million for Class C shares.
 
  Class A shares are not subject to an ongoing distribution fee and,
accordingly, receive correspondingly higher dividends per share. However,
because initial sales charges are deducted at the time of purchase for accounts
under $1 million, investors in Class A shares do not have all their funds
invested initially and, therefore, initially own fewer shares. Other investors
might determine that it is more advantageous to purchase either Class B shares
or Class C shares and have all their funds invested initially, although
remaining subject to a contingent deferred sales charge. Ongoing distribution
fees on Class B shares and Class C shares will be offset to the extent of the
additional funds originally invested and any return realized on those funds.
However, there can be no assurance as to the return, if any, which will be
realized on such additional funds. For investments held for ten years or more,
the relative value upon liquidation of the three classes tends to favor Class A
or Class B shares, rather than Class C shares.
 
                                       24
<PAGE>   25
 
  Class A shares may be appropriate for investors who prefer to pay the sales
charge up front, want to take advantage of the reduced sales charges available
on larger investments, wish to maximize their current income from the start,
prefer not to pay redemption charges and/or have a longer-term investment
horizon. In addition, the check writing privilege is only available for Class A
shares (see "Shareholder Services -- Shareholder Services Applicable to Class A
Shareholders Only -- Check Writing Privilege"). Class B shares may be
appropriate for investors who wish to avoid a front-end sales charge, put 100%
of their investment dollars to work immediately, and/or have a longer-term
investment horizon. Class C shares may be appropriate for investors who wish to
avoid a front-end sales charge, put 100% of their investment dollars to work
immediately, have a shorter-term investment horizon and/or desire a short
contingent deferred sales charge schedule.
 
  The distribution expenses incurred by the Distributor in connection with the
sale of the shares will be reimbursed, in the case of Class A shares, from the
proceeds of the initial sales charge and, in the case of Class B shares and
Class C shares, from the proceeds of the ongoing distribution fee and any
contingent deferred sales charge incurred upon redemption within five years or
one year, respectively, of purchase. Sales personnel of broker-dealers
distributing the Fund's shares and other persons entitled to receive
compensation for selling such shares may receive differing compensation for
selling such shares. INVESTORS SHOULD UNDERSTAND THAT THE PURPOSE AND FUNCTION
OF THE CONTINGENT DEFERRED SALES CHARGE AND ONGOING DISTRIBUTION FEE WITH
RESPECT TO THE CLASS B SHARES AND CLASS C SHARES ARE THE SAME AS THOSE OF THE
INITIAL SALES CHARGE WITH RESPECT TO CLASS A SHARES. See "Distribution Plans."
 
  GENERAL. Dividends paid by the Fund with respect to Class A, Class B and Class
C shares will be calculated in the same manner at the same time on the same day,
except that the distribution fees and any incremental transfer agency costs
relating to Class B or Class C shares will be borne by the respective class. See
"Distributions from the Fund." Shares of the Fund may be exchanged, subject to
certain limitations, for shares of the same class of other mutual funds advised
by the Adviser. See "Shareholder Services -- Exchange Privilege."
 
  The Trustees of the Fund have determined that currently no conflict of
interest exists between the classes of shares. On an ongoing basis, the Trustees
of the Fund, pursuant to their fiduciary duties under the Investment Company Act
of 1940 (the "1940 Act") and state laws, will seek to ensure that no such
conflict arises.

PURCHASE OF SHARES
- ------------------------------------------------------------------------------
 
GENERAL
 
  The Fund offers three classes of shares to the general public on a continuous
basis through the Distributor as principal underwriter, which is located at One
Parkview Plaza, Oakbrook Terrace, Illinois 60181. Shares are also offered
through members of the National Association of Securities Dealers, Inc. ("NASD")
who are acting as securities dealers ("dealers") and NASD members or eligible
non-NASD members who are acting as brokers or agents for investors ("brokers").
The term "dealers" and "brokers" are sometimes referred to herein as "authorized
dealers." Class A shares are sold with an initial sales charge; Class B shares
and Class C shares are sold without an initial sales charge and are subject to a
contingent deferred sales charge upon certain redemptions. See "Alternative
Sales Arrangements" for a discussion of factors to consider in selecting which
class of shares to purchase. Contact the Investor Services Department at (800)
421-5666 for further information and appropriate forms.
 
  Initial investments must be at least $500 and subsequent investments must be
at least $25. Both minimums may be waived by the Distributor for plans involving
periodic investments. Shares of the Fund may be sold in foreign countries where
permissible. The Fund and the Distributor reserve the right to refuse any order
for the purchase of shares. The Fund also reserves the right to suspend the sale
of the Fund's shares in response to conditions in the securities markets or for
other reasons.
 
   
  Shares may be purchased on any business day through authorized dealers. Shares
may also be purchased by completing the application accompanying this Prospectus
and forwarding the application, through the designated dealer, to the
shareholder service agent, ACCESS Investor Services, Inc., a wholly owned
subsidiary of Van Kampen American Capital ("ACCESS"). When purchasing shares of
the Fund, investors must specify whether the purchase is for Class A, Class B or
Class C shares.
    
 
  Shares are offered at the next determined net asset value per share, plus a
front-end or contingent deferred sales charge depending on the method of
purchasing shares chosen by the investor, as shown in the tables herein. Net
asset value per share is determined once daily as of the close of trading on the
New York Stock Exchange (the "Exchange") (currently 4:00 p.m., New York time)
each day the Exchange is open. Net asset value per share for each class is
determined by dividing the value of the Fund's securities, cash and other assets
(including accrued interest) attributable to such class, less all liabilities
(including accrued expenses) attributa-
 
                                       26
<PAGE>   27
 
ble to such class, by the total number of shares of the class outstanding. The
Fund's investments are valued by an independent pricing service.
 
  Generally, the net asset values per share of the Class A, Class B and Class C
shares are expected to be substantially the same. Under certain circumstances,
however, the per share net asset values of the Class A, Class B and Class C
shares may differ from one another, reflecting the daily expense accruals of the
distribution and the higher transfer agency fees applicable with respect to the
Class B and Class C shares and the differential in the dividends paid on the
classes of shares. The price paid for shares purchased is based on the net asset
value next computed plus applicable Class A sales charges after an order is
received by a dealer provided such order is transmitted to the Distributor prior
to the Distributor's close of business on such day. Orders received by dealers
after the close of the Exchange are priced based on the next close provided they
are received by the Distributor prior to the Distributor's close of business on
such day. It is the responsibility of dealers to transmit orders received by
them to the Distributor so they will be received prior to such time. Orders of
less than $500 are mailed by the dealer and processed at the offering price next
calculated after acceptance by ACCESS.
 
  Each class of shares represents an interest in the same portfolio of
investments of the Fund, has the same rights and is identical in all respects,
except that (i) Class B and Class C shares bear the expenses of the deferred
sales arrangement and any expenses (including the distribution fee and
incremental transfer agency costs) resulting from such sales arrangement, (ii)
generally, each class has exclusive voting rights with respect to approvals of
the Rule 12b-1 distribution plan pursuant to which its distribution fee and/or
service fee is paid which relate to a specific class, and (iii) Class B and
Class C shares are subject to a conversion feature. Each class has different
exchange privileges and certain different shareholder service options available.
See "Distribution Plans" and "Shareholder Services -- Exchange Privilege." The
net income attributable to Class B and Class C shares and the dividends payable
on Class B and Class C shares will be reduced by the amount of the distribution
fee and incremental expenses associated with such distribution fees. Sales
personnel of broker-dealers distributing the Fund's shares and other persons
entitled to receive compensation for selling such shares may receive differing
compensation for selling Class A, Class B or Class C shares.
 
  Agreements are in place which provide, among other things and subject to
certain conditions, for certain favorable distribution arrangements for shares
of the Fund, with subsidiaries of The Travelers Inc.
 
  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
 
                                       27
<PAGE>   28
 
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 intermediaries 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 the Distributor, 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. 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. All of the foregoing payments are made by
the Distributor out of its own assets. These programs will not change the price
an investor will pay for shares or the amount that a Fund will receive from such
sale.
 
CLASS A SHARES
 
  The public offering price of Class A shares is the next determined net asset
value plus a sales charge, as set forth below.

* No sales charge is payable at the time of purchase on investments of $1
  million or more, although for such investments the Fund imposes a contingent
  deferred sales charge of one percent in the event of certain redemptions
  within one year of the purchase. The contingent deferred sales charge incurred
  upon redemption is paid to the Distributor in reimbursement for
  distribution-related expenses. A commission will be paid to dealers who
  initiate and are responsible for purchases of $1 million or more as follows:
  one percent 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.

  In addition to the reallowances from the applicable public offering price
described above, the Distributor may, from time to time, pay or allow additional
reallowances or promotional incentives, in the form of cash or other
compensation, to dealers that sell shares of the Fund. Dealers which are
reallowed all or substantially all of the sales charges may be deemed to be
underwriters for purposes of the Securities Act of 1933.
 
  The Distributor may also pay financial institutions (which may include banks)
and other industry professionals that provide services to facilitate
transactions in shares of the Fund for their clients a transaction fee up to the
level of the reallowance allowable to dealers described above. Such financial
institutions, other industry professionals and dealers are hereinafter referred
to as "Service Organizations." Banks are currently prohibited under the
Glass-Steagall Act from providing certain underwriting or distribution services.
If banking firms were prohibited from acting in any capacity or providing any of
the described services, the Distributor would consider what action, if any,
would be appropriate. The Distributor does not believe that termination of a
relationship with a bank would result in any material adverse consequences to
the Fund. State securities laws regarding registration of banks and other
financial institutions may differ from the interpretations of federal law
expressed herein, and banks and other financial institutions may be required to
register as dealers pursuant to certain state laws.
 
   
QUANTITY DISCOUNTS
    
 
  Investors purchasing Class A shares may under certain circumstances be
entitled to pay reduced sales charges. The circumstances under which such
investors may pay reduced sales charges are described below.
 
  Investors, or their brokers, dealers or financial intermediaries, must notify
the Fund whenever a quantity discount is applicable to purchases. Upon such
notification, an investor will receive the lowest applicable sales charge.
Quantity discounts may be modified or terminated at any time. For more
information about quantity discounts, investors should contact their broker,
dealer or financial intermediary or the Distributor.
 
  A person eligible for a reduced sales charge includes an individual, their
spouse and minor children and any corporation, partnership or sole
proprietorship which is 100% owned, either alone or in combination, by any of
the foregoing; a trustee or other fiduciary purchasing for a single fiduciary
account, or a "company" as defined in Section 2(a)(8) of the 1940 Act.
 
   
  As used herein, "Participating Funds" refers to all open-end investment
companies distributed by the Distributor other than Van Kampen American Capital
Money Market Fund ("VK Money Market"), Van Kampen American Capital Tax
    
 
                                       29
<PAGE>   30
 
   
Free Money Fund ("VK Tax Free"), Van Kampen American Capital Reserve Fund
("Reserve") and The Govett Funds, Inc.
    
 
   
  Volume Discounts. The size of investment shown in the preceding table applies
to the total dollar amount being invested by any person in shares of the Fund
alone, or in any combination of shares of the Fund and shares of other
Participating Funds, although other Participating Funds may have different sales
charges.
    
 
  Cumulative Purchase Discount. The size of investment shown in the preceding
table may also be determined by combining the amount being invested in shares of
the Participating Funds plus the current offering price of all shares of the
Participating Funds which have been previously purchased and are still owned.
 
   
  Letter of Intent. A Letter of Intent provides an opportunity for an investor
to obtain a reduced sales charge by aggregating the investments over a 13-month
period to determine the sales charge as outlined in the table herein. The size
of investment shown in the preceding table also includes purchases of shares of
the Participating Funds over a 13-month period based on the total amount of
intended purchases plus the value of all shares of the Participating Funds
previously purchased and still owned. An investor may elect to compute the
13-month period starting up to 90 days before the date of execution of a Letter
of Intent. Each investment made during the period receives the reduced sales
charge applicable to the total amount of the investment goal. If the goal is not
achieved within the period, the investor must pay the difference between the
charges applicable to the purchases made and the charges previously paid. The
initial purchase must be for an amount equal to at least five percent of the
minimum total purchased amount of the level selected. If trades not initially
made under a Letter of Intent subsequently qualify for a lower sales charge
through the 90-day back-dating provisions, an adjustment will be made at the
expiration of the Letter of Intent to give effect to the lower charge. Such
adjustment in sales charge will be used to purchase additional shares for the
shareholder at the applicable discount category. Additional information is
contained in the application form accompanying this Prospectus.
    
 
   
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.
 
  Unit Fund Reinvestment Programs.  The Fund permits unitholders of unit
investment trusts to reinvest distributions from such trusts in Class A shares
of the
 
                                       30
<PAGE>   31
 
   
Fund, other Participating Funds, VK Money Market, VK Tax Free or Reserve 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 one percent 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 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 ACCESS with appropriate backup data
for each participating investor in a computerized format fully compatible with
ACCESS'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.
 
  NAV Purchase Options. Class A shares of the Fund may be purchased at net asset
value, upon written assurance that the purchase is made for investment purposes
and that the shares will not be resold except through redemption by the Fund,

      the amount invested, over a twelve month period following such
      transaction.
 
   
  (5) Trustees and other fiduciaries purchasing shares for retirement plans of

<PAGE>   33
 
CLASS B SHARES
 
  Class B shares are offered at the next determined net asset value. Class B
shares which are redeemed within five years of purchase are subject to a
contingent deferred sales charge at the rates set forth in the following table
charged as a percentage of the dollar amount subject thereto. The charge is
assessed on an amount equal to the lesser of the then current market value or
the cost of the shares being redeemed. Accordingly, no sales charge is imposed
on increases in net asset value above the initial purchase price. In addition,
no charge is assessed on shares derived from reinvestment of dividends or
capital gains distributions.
 
  The amount of the contingent deferred sales charge, if any, varies depending
on the number of years from the time of payment for the purchase of Class B
shares until the time of redemption of such shares. Solely for purposes of
determining the number of years from the time of any payment for the purchase of
shares, all payments during a month are aggregated and deemed to have been made
on the last day of the month.

  In determining whether a contingent deferred sales charge is applicable to a
redemption, it is assumed that the redemption is first, of any shares in the
shareholder's Fund account that are not subject to a contingent deferred sales
charge, second, of shares held for over five years or shares acquired pursuant
to reinvestment of dividends or distributions and third, of shares held longest
during the five year period.
    
 
  To provide an example, assume an investor purchased 100 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 ten
additional shares upon dividend reinvestment. If at such time the investor makes
his or her first redemption of 50 shares (proceeds of $600), ten 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 is subject to a deferred sales charge at a
rate of four percent (the applicable rate in the second year after purchase).
 
                                       33
<PAGE>   34
 
  A commission or transaction fee of four percent of the purchase amount will be
paid to broker-dealers and other Service Organizations at the time of purchase.
Additionally, the Distributor may, from time to time, pay additional promotional
incentives, in the form of cash or other compensation, to Service Organizations
that sell Class B shares of the Fund.
 
CLASS C SHARES
 
  Class C shares are offered at the next determined net asset value. Class C
shares which are redeemed within the first year of purchase are subject to a
contingent deferred sales charge of one percent. The charge is assessed on an
amount equal to the lesser of the then current market value or the cost of the
shares being redeemed. Accordingly, no sales charge is imposed on increases in
net asset value above the initial purchase price. In addition, no charge is
assessed on shares derived from reinvestment of dividends or capital gains
distributions.
 
  In determining whether a contingent deferred sales charge is applicable to a
redemption, the calculation is determined in the manner that results in the
lowest possible rate being charged. Therefore, it is assumed that the redemption
is first of any shares in the shareholder's Fund account that are not subject to
a contingent deferred sales charge and second, of shares held for more than one
year or shares acquired pursuant to reinvestment of dividends or distributions.
 
   
  A commission or transaction fee of one percent of the purchase amount will be
paid to broker-dealers and other Service Organizations at the time of purchase.
Broker-dealers and other Service Organizations will also be paid ongoing
commissions and transaction fees of up to 0.75% of the average daily net assets
of the Fund's Class C shares for the second through tenth year after purchase.
Additionally, the Distributor may, from time to time, pay additional promotional
incentives, in the form of cash or other compensation, to Service Organizations
that sell Class C shares of the Fund.
    
 
WAIVER OF CONTINGENT DEFERRED SALES CHARGE
 
  The contingent deferred sales charge is waived on redemptions of Class B and
Class C shares (i) following the death or disability (as defined in the Code) of
a shareholder, (ii) in connection with certain distributions from an IRA or
other retirement plan, (iii) pursuant to the Fund's systematic withdrawal plan
but limited to 12% annually of the initial value of the account, and (iv)
effected pursuant to the right of the Fund to liquidate a shareholder's account
as described herein under "Redemption of Shares." The contingent deferred sales
charge is also waived on redemptions of Class C shares as it relates to the
reinvestment of redemption proceeds in shares of the same class of the Fund
within 120 days after redemption. See the Statement of Additional Information
for further discussion of waiver provisions.

SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------
 
  The Fund offers a number of shareholder services designed to facilitate
investment in its shares at little or no extra cost to the investor. The
following is a description of these services.
 
SHAREHOLDER SERVICES APPLICABLE TO ALL CLASSES
 
  INVESTMENT ACCOUNT. Each shareholder has an investment account under which
shares are held by ACCESS. Except as described herein, after each share
transaction in an account, the shareholder receives a statement showing the
activity in the account. Each shareholder who has an account in certain of the
Participating Funds or Reserve, may receive statements quarterly from ACCESS
showing any reinvestments of dividends and capital gains distributions and any
other activity in the account since the preceding statement. Such shareholders
also will receive separate confirmations for each purchase or sale transaction
other than reinvestment of dividends and capital gains distributions and
systematic purchases or redemptions. Additions to an investment account may be
made at any time by purchasing shares through authorized investment dealers or
by mailing a check directly to ACCESS.
 
  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 thereof. In addition, if such certificates are lost the shareholder
must write to Van Kampen American Capital Funds, c/o ACCESS, P.O. Box 418256,
Kansas City, MO 64141-9256, requesting an "affidavit of loss" and obtain a
Surety Bond in a form acceptable to ACCESS. On the date the letter is received
ACCESS will calculate no more than two percent of the net asset value of the
issued shares, and bill the party to whom the certificate was mailed.
 
  REINVESTMENT PLAN. A convenient way for investors to accumulate additional
shares is by accepting dividends and capital gains distributions in shares of
the Fund. Such shares are acquired at net asset value (without sales charge) on
the record date. Unless the shareholder instructs otherwise, the reinvestment
plan is automatic. This instruction may be made by telephone by calling (800)
421-5666 ((800) 772-8889 for the hearing impaired) or in writing to ACCESS. The
investor may, on the initial application or prior to any declaration, instruct
that dividends be paid in cash and capital gains distributions be reinvested at
net asset value, or that both dividends and capital gains distributions be paid
in cash.
 
  AUTOMATIC INVESTMENT PLAN. An automatic investment plan is available under
which a shareholder can authorize ACCESS to charge a bank account on a regular
 
                                       35
<PAGE>   36
 
basis to invest pre-determined amounts in the Fund. Additional information is
available from the Distributor or authorized dealers.
 
  AUTOMATED CLEARING HOUSE ("ACH") DEPOSITS.  Holders of Class A shares can use
ACH to have redemption proceeds deposited electronically into their bank
accounts. Redemptions transferred to a bank account via the ACH plan are
available to be credited to the account on the second business day following
normal payment. In order to utilize this option, the shareholder's bank must be
a member of Automated Clearing House. In addition, the shareholder must fill out
the appropriate section of the account application. The shareholder must also
include a voided check or deposit slip from the bank account into which
redemptions are to be deposited together with the completed application. Once
ACCESS has received the application and the voided check or deposit slip, such
shareholder's designated bank account, following any redemption, will be
credited with the proceeds of such redemption. Once enrolled in the ACH plan, a
shareholder may terminate participation at any time by writing ACCESS.
 
   
  DIVIDEND DIVERSIFICATION. A shareholder may, upon written request or by
completing the appropriate section of the application form accompanying this
Prospectus or by calling (800) 421-5666 ((800) 772-8889 for the hearing
impaired), elect to have all dividends and other distributions paid on a Class
A, Class B or Class C account in the Fund invested into a pre-existing Class A,
Class B or Class C account in any of the Participating Funds, VK Money Market,
VK Tax Free or Reserve.
    
 
  If a qualified, pre-existing account does not exist, the shareholder must
establish a new account subject to minimum investment and other requirements of
the fund into which distributions would be invested. Distributions are invested
into the selected fund at its net asset value as of the payable date of the
distribution only if shares of such selected funds have been registered for sale
in the investor's state.
 
   
  EXCHANGE PRIVILEGE. Shares of the Fund or of any Participating Fund other than
Van Kampen American Capital Government Target Fund ("Government Target"), may be
exchanged for shares of the same class of any other fund without sales charge,
provided that shares of certain other Van Kampen American Capital fixed-income
funds may not be exchanged within 30 days of acquisition without Advisor
approval. Shares of Government Target may be exchanged for Class A shares of the
Fund without sales charge. Class A shares of VK Money Market, VK Tax Free or
Reserve that were not acquired in exchange for Class B or Class C shares of a
Participating Fund may be exchanged for Class A shares of the Fund upon payment
of the excess, if any, of the sales charge rate applicable to the shares being
acquired over the sales charge rate previously paid. Shares of VK Money Market,
VK Tax Free or Reserve acquired through an exchange of Class B or Class C shares
may be exchanged only for the same class of shares of a Participating Fund
without incurring a contingent deferred sales charge. Shares of
    
 
                                       36
<PAGE>   37
 
   
any Participating Fund, VK Money Market, VK Tax Free or Reserve may be exchanged
for shares of any other Participating Fund if shares of that Participating Fund
are available for sale; however, during periods of suspension of sales, shares
of a Participating Fund may be available for sale only to existing shareholders
of a Participating Fund.
    
 
  Class B and Class C shareholders of the Fund have the ability to exchange
their shares ("original shares") for the same class of shares of any other Van
Kampen American Capital fund that offers such shares ("new shares") in an amount
equal to the aggregate net asset value of the original shares, without the
payment of any contingent deferred sales charge otherwise due upon redemption of
the original shares. For purposes of computing the contingent deferred sales
charge payable upon a disposition of the new shares, the holding period for the
original shares is added to the holding period of the new shares. Class B or
Class C shareholders would remain subject to the contingent deferred sales
charge imposed by the original fund upon their redemption from the Van Kampen
American Capital complex of funds. The contingent deferred sales charge is based
on the holding period requirement of the original fund.
 
  Shares of the fund to be acquired must be registered for sale in the
investor's state. Exchanges of shares are sales and may result in a gain or loss
for federal income tax purposes, although if the shares exchanged have been held
for less than 91 days, the sales charge paid on such shares is not included in
the tax basis of the exchanged shares, but is carried over and included in the
tax basis of the shares acquired. See the Statement of Additional Information.
 
   
  A shareholder wishing to make an exchange may do so by sending a written
request to ACCESS or by contacting the telephone transaction line at (800)
421-5684. A shareholder automatically has telephone exchange privileges unless
otherwise designated in the application form accompanying by this Prospectus.
Van Kampen American Capital and its subsidiaries, including ACCESS
(collectively, "VKAC"), and the Fund employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications, and providing written confirmation of instructions communicated
by telephone. If reasonable procedures are employed, neither VKAC nor the Fund
will be liable for following telephone instructions which it reasonably believes
to be genuine. VKAC and the Fund may be liable for any losses due to
unauthorized or fraudulent instructions if reasonable procedures are not
followed. Exchanges are effected at the net asset value per share next
calculated after the request is received in good order with adjustment for any
additional sales charge. See "Purchase of Shares" and "Redemption of Shares." If
the exchanging shareholder does not have an account in the fund whose shares are
being acquired, a new account will be established with the
    
 
                                       37
<PAGE>   38
 
   
same registration, dividend and capital gain options (except dividend
diversification) and dealer of record as the account from which shares are
exchanged, unless otherwise specified by the shareholder. In order to establish
a systematic withdrawal plan for the new account or reinvest dividends from the
new account into another fund, however, an exchanging shareholder must file a
specific written request. The Fund reserves the right to reject any order to
acquire its shares through exchange. In addition, the Fund may modify, restrict
or terminate the exchange privilege at any time on 60 days' notice to its
shareholders of any termination or material amendment.
    
 
  A prospectus of any of these mutual funds may be obtained from any authorized
dealer or the Distributor. An investor considering an exchange to one of such
funds should refer to the prospectus for additional information regarding such
fund prior to investing.
 
  SYSTEMATIC WITHDRAWAL PLAN. Any investor whose shares in a single account
total $10,000 or more at the offering price next computed after receipt of
instructions may establish a monthly, quarterly, semi-annual or annual
withdrawal plan. This plan provides for the orderly use of the entire account,
not only the income but also the capital, if necessary. Each withdrawal
constitutes a redemption of shares on which any capital gain or loss will be
recognized. The planholder may arrange for monthly, quarterly, semi-annual or
annual checks in any amount, not less than $25.
 
  Class B and Class C shareholders who establish a withdrawal plan may redeem up
to 12% annually of the shareholder's initial account balance without incurring a
contingent deferred sales charge. Initial account balance means the amount of
the shareholder's investment in the Fund at the time the election to participate
in the plan is made. See "Purchase of Shares -- Waiver of Contingent Deferred
Sales Charge" and the Statement of Additional Information.
 
  Under the plan, sufficient shares of the Fund are redeemed to provide the
amount of the periodic withdrawal payment. Dividends and capital gains
distributions on shares held under the plan are reinvested in additional shares
at the next determined net asset value. If periodic withdrawals continuously
exceed reinvested dividends and capital gains distributions, the shareholder's
original investment will be correspondingly reduced and ultimately exhausted.
Withdrawals made concurrently with the purchase of additional shares ordinarily
will be disadvantageous to the shareholder because of the duplication of sales
charges. Any taxable gain or loss will be recognized by the shareholder upon the
redemption of shares.
 
SHAREHOLDER SERVICES APPLICABLE TO CLASS A SHAREHOLDERS ONLY
 
  CHECK WRITING PRIVILEGE. A Class A shareholder holding shares of the Fund for
which certificates have not been issued and which are in a non-escrow status may
 
                                       38
<PAGE>   39
 
appoint ACCESS as agent by completing the AUTHORIZATION FOR REDEMPTION BY CHECK
form and the appropriate section of the application and returning the form and
the application to ACCESS. Once the form is properly completed, signed and
returned to ACCESS, a supply of checks drawn on State Street Bank and Trust
Company ("State Street Bank") will be sent to the Class A shareholder. These
checks may be made payable by the Class A shareholder to the order of any person
in any amount of $100 or more.
 
  When a check is presented to State Street Bank for payment, full and
fractional Class A shares required to cover the amount of the check are redeemed
from the Class A shareholder's account by ACCESS at the next determined net
asset value. Check writing redemptions represent the sale of shares. Any gain or
loss realized on the sale of shares is a taxable event. See "Redemption of
Shares."
 
  Checks will not be honored for redemption of Class A shares held less than 15
calendar days, unless such Class A shares have been paid for by bank wire. Any
Class A shares for which there are outstanding certificates may not be redeemed
by check. If the amount of the check is greater than the proceeds of all
uncertificated shares held in the shareholder's Class A account, the check will
be returned and the shareholder may be subject to additional charges. A Class A
shareholder may not liquidate the entire account by means of a check. The check
writing privilege may be terminated or suspended at any time by the Fund or
State Street Bank. Accounts that are subject to backup withholding are not
eligible for the privilege. A "stop payment" system is not available on these
checks. See the Statement of Additional Information for further information
regarding the establishment of the privilege.

REDEMPTION OF SHARES
- ------------------------------------------------------------------------------
 
  REGULAR REDEMPTIONS. Shareholders may redeem for cash some or all of their
shares of the Fund at any time. To do so, a written request in proper form must
be sent directly to ACCESS, P.O. Box 418256, Kansas City, Missouri 64141-9256.
Shareholders may also place redemption requests through an authorized investment
dealer. Orders received from dealers must be at least $500 unless transmitted
via the FUNDSERV network. The redemption price for such shares is the net asset
value next calculated after an order is received by a dealer provided such order
is transmitted to the Distributor prior to the Distributor's close of business
on such day. It is the responsibility of dealers to transmit redemption requests
received by them to the Distributor so they will be received prior to such time.
 
  As described herein under "Purchase of Shares," redemptions of Class B and
Class C shares are subject to a contingent deferred sales charge. In addition, a
contingent deferred sales charge of one percent may be imposed on certain
redemptions of Class A shares made within one year of purchase for investments
of
 
                                       39
<PAGE>   40
 
$1 million or more and for certain qualified 401(k) retirement plans. The
contingent deferred sales charge incurred upon redemption is paid to the
Distributor in reimbursement for distribution-related expenses. See "Purchase of
Shares." A custodian of a retirement plan account may charge fees based on the
custodian's fee schedule.
 
  The request for redemption must be signed by all persons in whose names the
shares are registered. Signatures must conform exactly to the account
registration. If the proceeds of the redemption exceed $50,000, or if the
proceeds are not to be paid to the record owner at the record address, or if the
record address has changed within the previous 30 days, signature(s) must be
guaranteed by one of the following: a bank or trust company; a broker-dealer; a
credit union; a national securities exchange, registered securities association
or clearing agency; a savings and loan association; or a federal savings bank.
 
  Generally, a properly signed written request with any required signature
guarantee is all that is required for a redemption. In some cases, however,
other documents may be necessary. For example, although the Fund normally does
not issue certificates for shares, it will do so if a special request has been
made to ACCESS. In the case of shareholders holding certificates, the
certificates for the shares being redeemed must accompany the redemption
request. In the event the redemption is requested by a corporation, partnership,
trust, fiduciary, executor or administrator, and the name and title of the
individual(s) authorizing such redemption is not shown in the account
registration, a copy of the corporate resolution or other legal documentation
appointing the authorized signer and certified within the prior 60 days must
accompany the redemption request.
 
   
  In the case of redemption requests sent directly to ACCESS, the redemption
price is the net asset value per share next determined after the request is
received in proper form. Payment for shares redeemed is made by check mailed
within seven days after acceptance by ACCESS of the request and any other
necessary documents in proper order. Such payment may be postponed or the right
of redemption suspended as provided by the rules of the SEC. If the shares to be
redeemed have been recently purchased by check, ACCESS may delay mailing a
redemption check until the purchase check has cleared, usually a period of up to
15 days. Any taxable gain or loss will be recognized by the shareholder upon
redemption of shares.
    
 
  The Fund may redeem any shareholder account with a net asset value on the date
of the notice of redemption less than the minimum investment as specified by the
Trustees. At least 60 days advance written notice of any such involuntary
redemption is required and the shareholder is given an opportunity to purchase
the required value of additional shares at the next determined net asset value
without sales charge. Any applicable contingent deferred sales charge will be
deducted from the proceeds of this redemption. Any involuntary redemption may
only occur if the
 
                                       40
<PAGE>   41
 
shareholder account is less than the minimum initial investment due to
shareholder redemptions.
 
   
  TELEPHONE REDEMPTIONS. In addition to the regular redemption procedures
previously set forth, the Fund permits redemption of shares by telephone and for
redemption proceeds to be sent to the address of record for the account or to
the bank account of record as described below. To establish such privilege, a
shareholder must complete the appropriate section of the application form
accompanying this Prospectus or call the Fund at (800) 421-5666 to request that
a copy of the Telephone Redemption Authorization form be sent to them for
completion. To redeem shares, contact the telephone transaction line at (800)
421-5684. VKAC and the Fund employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications, and providing written confirmation of instructions communicated
by telephone. If reasonable procedures are employed, neither VKAC nor the Fund
will be liable for following telephone instructions which it reasonably believes
to be genuine. VKAC and the Fund may be liable for any losses due to
unauthorized or fraudulent instructions if reasonable procedures are not
followed. Telephone redemptions may not be available if the shareholder cannot
reach ACCESS by telephone, whether because all telephone lines are busy or for
any other reason; in such case, a shareholder would have to use the Fund's
regular redemption procedure previously described. Requests received by ACCESS
prior to 4:00 p.m., New York time, on a regular business day will be processed
at the net asset value per share determined that day. These privileges are
available for the following types of non-retirement accounts: individual
accounts, joint accounts and accounts of minors with custodians acting on their
behalf. The telephone redemption privilege is not available for shares
represented by certificates. If an account has multiple owners, ACCESS may rely
on the instructions of any one owner.
    
 
  For redemptions authorized by telephone, amounts of $50,000 or less may be
redeemed daily if the proceeds are to be paid by check and amounts of at least
$1,000 up to $1 million may be redeemed daily if the proceeds are to be paid by
wire. The proceeds must be payable to the shareholder(s) of record and sent to
the address of record for the account or wired directly to their predesignated
bank account. This privilege is not available if the address of record has been
changed within 30 days prior to a telephone redemption request. Proceeds from
redemptions are expected to be wired on the next business day following the date
of redemption. The Fund reserves the right at any time to terminate, limit or
otherwise modify this redemption privilege.
 
  REDEMPTION UPON DISABILITY. The Fund will waive the contingent deferred sales
charge on redemptions following the disability of a Class B and Class C share-
 
                                       41
<PAGE>   42
 
holder. An individual will be considered disabled for this purpose if he or she
meets the definition thereof in Section 72(m)(7) of the Code, which in pertinent
part defines a person as disabled if such person "is unable to engage in any
substantial gainful activity by reason of any medically determinable physical or
mental impairment which can be expected to result in death or to be of
long-continued and indefinite duration." While the Fund does not specifically
adopt the balance of the Code's definition which pertains to furnishing the
Secretary of Treasury with such proof as he or she may require, the Distributor
will require satisfactory proof of disability before it determines to waive the
contingent deferred sales charge on Class B and Class C shares.
 
  In cases of disability, the contingent deferred sales charge on Class B and
Class C shares will be waived where the disabled person is either an individual
shareholder or owns the shares as a joint tenant with right of survivorship or
is the beneficial owner of a custodial or fiduciary account, and where the
redemption is made within one year of the initial determination of disability.
This waiver of the contingent deferred sales charge on Class B and Class C
shares applies to a total or partial redemption, but only to redemptions of
shares held at the time of the initial determination of disability.
 
  REINSTATEMENT PRIVILEGE. A Class A or Class B shareholder who has redeemed
shares of the Fund may reinstate any portion or all of the net proceeds of such
redemption in Class A shares of the Fund. A Class C shareholder who has redeemed
shares of the Fund may reinstate any portion or all of the net proceeds of such
redemption in Class C shares of the Fund with credit given for any contingent
deferred sales charge paid upon such redemption. Such reinstatement is made at
the net asset value (without sales charge except as described under "Shareholder
Services -- Exchange Privilege") next determined after the order is received,
which must be within 120 days after the date of the redemption. See "Purchase of
Shares -- Waiver of Contingent Deferred Sales Charge" and the Statement of
Additional Information.
 
- ------------------------------------------------------------------------------
DISTRIBUTION PLANS
- ------------------------------------------------------------------------------
 
  Rule 12b-1 adopted by the SEC under the 1940 Act permits an investment company
to directly or indirectly pay expenses associated with the distribution of its
shares ("distribution expenses") and servicing of its shareholders in accordance
with a plan adopted by the investment company's board of directors and approved
by its shareholders. Pursuant to such Rule, the Trustees of the Fund, and the
shareholders of each class have adopted three Distribution Plans hereinafter
referred to as the "Class A Plan," the "Class B Plan" and the "Class C Plan."
Each Distribution Plan is in compliance with the Rules of Fair Practice of the
NASD ("NASD Rules") applicable to mutual fund sales charges. The NASD Rules
limit
 
                                       42
<PAGE>   43
 
the annual distribution charges that a mutual fund may impose on a class of
shares. The NASD Rules also limit the aggregate amount which the Fund may pay
for such distribution costs. Under the Class A Plan, the Fund pays a service fee
to the Distributor at an annual rate of up to 0.25% of the Fund's aggregate
average daily net assets attributable to the Class A shares. Such payments to
the Distributor under the Class A Plan are based on an annual percentage of the
value of Class A shares held in shareholder accounts for which such Service
Organizations are responsible at the rates of 0.15% annually with respect to
Class A shares in such accounts on September 29, 1989 and 0.25% annually with
respect to Class A shares issued after that date. Under the Class B Plan and the
Class C Plan, the Fund pays a service fee to the Distributor at an annual rate
of up to 0.25% and a distribution fee at an annual rate of up to 0.75% of the
Fund's aggregate average daily net assets attributable to the Class B shares or
Class C shares to reimburse the Distributor for service fees paid by it to
Service Organizations and for its distribution costs.
 
  The Distributor uses the Class A, Class B and Class C service fees to
compensate Service Organizations for personal services and/or the maintenance of
shareholder accounts. Under the Class B Plan, the Distributor receives
additional payments from the Fund in the form of a distribution fee at the
annual rate of up to 0.75% of the net assets of the Class B shares as
reimbursement for (i) upfront commissions and transaction fees of up to four
percent of the purchase price of Class B shares purchased by the clients of
broker-dealers and other Service Organizations, and (ii) other distribution
expenses as described in the Statement of Additional Information. Under the
Class C Plan, the Distributor receives additional payments from the Fund in the
form of a distribution fee at the annual rate of up to 0.75% of the net assets
of the Class C shares as reimbursement for (i) upfront commissions and
transaction fees of up to 0.75% of the purchase price of Class C shares
purchased by the clients of broker-dealers and other Service Organizations and
ongoing commissions and transaction fees of up to 0.75% of the average daily net
assets of the Fund's Class C shares, and (ii) other distribution expenses as
described in the Statement of Additional Information.
 
  In adopting the Class A Plan, the Class B Plan and the Class C Plan, the
Trustees of the Fund determined that there was a reasonable likelihood that such
Plans would benefit the Fund and its shareholders. Information with respect to
distribution and service revenues and expenses is presented to the Trustees each
year for their consideration in connection with their deliberations as to the
continuance of the Distribution Plans. In their review of the Distribution
Plans, the Trustees are asked to take into consideration expenses incurred in
connection with the distribution and servicing of each class of shares
separately. The sales charge and distribution fee, if any, of a particular class
will not be used to subsidize the sale of shares of the other classes.
 
                                       43
<PAGE>   44
 
  Service expenses accrued by the Distributor in one fiscal year may not be paid
from the Class A service fees received from the Fund in subsequent fiscal years.
Thus, if the Class A Plan were terminated or not continued, no amounts (other
than current amounts accrued but not yet paid) would be owed by the Fund to the
Distributor.
 
  The distribution fee attributable to Class B or Class C shares is designed to
permit an investor to purchase such shares without the assessment of a front-end
sales load and at the same time permit the Distributor to compensate Service
Organizations with respect to such shares. In this regard, the purpose and
function of the combined contingent deferred sales charge and distribution fee
are the same as those of the initial sales charge with respect to the Class A
shares of the Fund in that in both cases such charges provide for the financing
of the distribution of the Fund's shares.
 
   
  Actual distribution expenditures paid by the Distributor with respect to Class
B or Class C shares for any given year are expected to exceed the fees received
pursuant to the Class B Plan and Class C Plan and payments received pursuant to
contingent deferred sales charges. Such excess will be carried forward and may
be reimbursed by the Fund or its shareholders from payments received through
contingent deferred sales charges in future years and from payments under the
Class B Plan and Class C Plan so long as such Plans are in effect. For example,
if in a fiscal year the Distributor incurred distribution expenses under the
Class B Plan of $1 million, of which $500,000 was recovered in the form of
contingent deferred sales charges paid by investors and $400,000 was reimbursed
in the form of payments made by the Fund to the Distributor under the Class B
Plan, the balance of $100,000 would be subject to recovery in future fiscal
years from such sources. For the plan year ended June 30, 1994, the unreimbursed
expenses incurred by the Distributor under the Class B Plan and carried forward
were approximately $1.5 million or 4.25% of the Class B shares' average daily
net assets. The unreimbursed expenses incurred by the Distributor under the
Class C Plan from August 30, 1993 (inception of Class C shares) through June 30,
1994, and carried forward were approximately $118,000 or 1.71% of the Class C
shares' average daily net assets.
    
 
  If the Class B Plan or Class C Plan was terminated or not continued, the Fund
would not be contractually obligated to pay and has no liability to the
Distributor for any expenses not previously reimbursed by the Fund or recovered
through contingent deferred sales charges.
 
- ------------------------------------------------------------------------------
DISTRIBUTIONS FROM THE FUND
- ------------------------------------------------------------------------------
 
  DIVIDEND POLICY. The Fund distributes substantially all of its net investment
income in monthly dividends to shareholders. The Fund intends to distribute
after
 
                                       44
<PAGE>   45
 
the end of a fiscal year the net capital gains, if any, realized during the
fiscal year, except to the extent that such gains are offset by capital loss
carryovers. Unless the shareholder instructs otherwise, dividends and
distributions are automatically applied to purchase shares of the Fund at net
asset value. See "Shareholder Services -- Reinvestment Plan."
 
  The per share dividends on Class B and Class C shares of the Fund will be
lower than the per share dividends on Class A shares of the Fund as a result of
the distribution fees and higher incremental transfer agency fees applicable to
such classes of shares.
 
- ------------------------------------------------------------------------------
TAX STATUS
- ------------------------------------------------------------------------------
 
  FEDERAL INCOME TAXES. The Fund has qualified and intends to be taxed as a
regulated investment company under the Code. By qualifying as a regulated
investment company, the Fund is not subject to federal income taxes to the
extent it distributes its net investment income and net realized capital gains.
In addition, the Fund intends to continue to invest in sufficient Municipal
Bonds to permit payment of "exempt-interest dividends" (as defined in the Code).
Dividends paid by the Fund from the net tax-exempt interest earned from
Municipal Bonds qualify as exempt-interest dividends if, at the close of each
quarter of the Fund's fiscal year, at least 50% of the value of its total assets
consists of Municipal Bonds.
 
  The Omnibus Budget Reconciliation Act of 1993, which was signed into law on
August 10, 1993, included certain provisions intended to prevent the conversion
of ordinary income into capital gains. One such provision affects tax-exempt
securities by requiring that gains on such securities purchased at a market
discount be treated as ordinary income to the extent of the accrued market
discount, if the securities are acquired after April 30, 1993. Such securities
were exempt from the market discount rules under prior law.
 
  Except as provided below, exempt-interest dividends paid to shareholders are
not includable in the shareholders' gross income for federal income tax
purposes. For each of the last three fiscal years of the Fund, over 99% of the
dividends paid by the Fund were exempt-interest dividends. The percentage of
income that is tax-exempt is applied uniformly to all dividends paid during each
fiscal year. This percentage may differ from the actual tax-exempt percentage
during any particular month.
 
  Interest on certain "private-activity bonds" issued after August 7, 1986, is
an item of tax preference subject to the alternative minimum tax on individuals
and corporations. The Fund invests a portion of its assets in such
private-activity bonds so that a portion of its exempt-interest dividends is an
item of tax preference to the extent such dividends represent interest received
from these private-activity bonds. For the fiscal year ended September 30, 1994,
approximately 12% of the Fund's
 
                                       45
<PAGE>   46
 
income consisted of interest on private-activity bonds which is an item of tax
preference. The Tax Reform Act of 1986 also imposed per capita volume
limitations on certain private-activity bonds which could limit the amount of
such bonds available for investment by the Fund.
 
  Shareholders are notified annually of the federal tax status of dividends and
any capital gains distributions.
 
  Individuals whose modified income exceeds a base amount are subject to federal
income tax on up to one-half of their Social Security benefits. Modified income
includes adjusted gross income, one-half of Social Security benefits and
tax-exempt interest, including tax-exempt interest dividends from the Fund.
 
  To avoid being subject to a 31% federal back-up withholding on dividends
(except exempt-interest dividends), distributions and redemption payments,
shareholders must furnish the Fund with a certification of their correct
taxpayer identification number.
 
  Dividends and distributions paid by the Fund have the effect of reducing net
asset value per share on the record date by the amount of the payment.
Therefore, a dividend or distribution of record shortly after the purchase of
shares by an investor represents, in substance, a return of capital to the
investor, even though subject to income taxes to the extent discussed herein.
 
  The foregoing is only a brief summary of some of the important tax
considerations generally affecting the Fund and its investors who are U.S.
residents or U.S. corporations. Additional tax information of relevance to
particular investors, including investors who may be "substantial users" of
facilities financed by Municipal Bonds, is contained in the Statement of
Additional Information. Investors are urged to consult their tax advisers with
specific reference to their own tax situation. Foreign investors should consult
their own counsel for further information as to the U.S. and their country of
residence or citizenship tax consequences of receipt of dividends and
distributions from the Fund.
 
  FEDERAL INCOME TAX ASPECTS OF FUTURES AND OPTIONS. The Fund's ability to
engage in transactions in listed futures contracts and related options may be
limited by provisions of the Code, including the requirement that the Fund
derive less than 30% of its gross income from the sale or other disposition of
securities held for less than three months. Gains and losses recognized by the
Fund from transactions in futures contracts and options generally constitute
capital gains and losses for federal income tax purposes. See "Federal Tax
Information" in the Statement of Additional Information. To the extent such
activities result in net realized short-term capital gains which are distributed
to shareholders, such distributions constitute taxable ordinary income. To the
extent such activities result in net realized long-term capital gains which are
distributed to shareholders, such distributions constitute taxable long-term
capital gains.
 
                                       46
<PAGE>   47
 
  STATE AND LOCAL TAXES. The exemption of interest income for federal income tax
purposes may not result in similar exemptions under the laws of a particular
state or local taxing authority. Income distributions may be taxable to
shareholders under state or local law as dividend income even though a portion
of such distributions may be derived from interest on tax-exempt obligations
which, if realized directly, would be exempt from such income taxes. It is
recommended that shareholders consult their tax advisers for information in this
regard. The Fund reports annually to its shareholders the percentage and source,
on a state-by-state basis, of interest income earned on Municipal Bonds held by
the Fund during the preceding year. Distributions paid by the Fund from sources
other than tax-exempt interest are generally subject to taxation at the state
and local levels.
 
- ------------------------------------------------------------------------------
FUND PERFORMANCE
- ------------------------------------------------------------------------------
 
  From time to time, the Fund may advertise its total return for prior periods.
Any such advertisement would include at least average annual total return
quotations for one, five and ten year periods. Other total return quotations,
aggregate or average, over other time periods may also be included.
 
  The total return of the Fund for a particular period represents the increase
(or decrease) in the value of a hypothetical investment in the Fund from the
beginning to the end of the period. Total return is calculated by subtracting
the value of the initial investment from the ending value and showing the
difference as a percentage of the initial investment; the calculation assumes
the initial investment is made at the current maximum public offering price
(which includes a maximum sales charge of 4.75% for Class A shares); that all
income dividends or capital gains distributions during the period are reinvested
in Fund shares at net asset value; and that any applicable contingent deferred
sales charge has been paid. The Fund's total return will vary depending on
market conditions, the securities comprising the Fund's portfolio, the Fund's
operating expenses and unrealized net capital gains or losses during the period.
Total return is based on historical earnings and asset value fluctuations and is
not intended to indicate future performance. No adjustments are made to reflect
any income taxes payable by shareholders on dividends and distributions paid by
the Fund or to reflect the fact no 12b-1 fees were incurred prior to October 1,
1989.
 
  Average annual total return quotations for periods of two or more years are
computed by finding the average annual compounded rate of return over the period
that would equate the initial amount invested to the ending redeemable value.
 
  Yield and total return are calculated separately for Class A, Class B and
Class C shares. Class A total return figures include the maximum sales charge of
4.75%; Class B and Class C total return figures include any applicable
contingent deferred
 
                                       47
<PAGE>   48
 
sales charge. Because of the differences in sales charges and distribution fees,
the total returns for each of the classes will differ.
 
  In addition to total return information, the Fund may also advertise its
current "yield." Yield figures are based on historical earnings and are not
intended to indicate future performance. Yield is determined by analyzing the
Fund's net income per share for a 30-day (or one month) period (which period
will be stated in the advertisement), and dividing by the maximum offering price
per share on the last day of the period. A "bond equivalent" annualization
method is used to reflect a semiannual compounding. The Fund's "tax-equivalent
yield" is calculated by determining the rate of return that would have to be
achieved on a fully taxable investment to produce the after-tax equivalent of
the Fund's yield, assuming certain tax brackets for a Fund shareholder.
 
  For purposes of calculating yield quotations, net income is determined by a
standard formula prescribed by the SEC to facilitate comparison with yields
quoted by other investment companies. Net income computed for this formula
differs from net income reported by the Fund in accordance with generally
accepted accounting principles and from net income computed for federal income
tax reporting purposes. Thus the yield computed for a period may be greater or
less than the Fund's then current dividend rate.
 
  The Fund's yield is not fixed and will fluctuate in response to prevailing
interest rates and the market value of portfolio securities, and as a function
of the type of securities owned by the Fund, portfolio maturity and the Fund's
expenses.
 
  Yield quotations should be considered relative to changes in the net asset
value of the Fund's shares, the Fund's investment policies, and the risks of
investing in shares of the Fund. The investment return and principal value of an
investment in the Fund will fluctuate so that an investor's shares, when
redeemed, may be worth more or less than their original cost.
 
  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. 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.
 
                                       48
<PAGE>   49
 
   
  In reports or other communications to shareholders or in advertising material,
the Fund may compare its performance with that of other mutual funds as listed
in the ratings or rankings prepared by Lipper Analytical Services, Inc.,
Morningstar Mutual Funds or similar independent services which monitor the
performance of mutual funds; or with municipal bond indices, such as Lehman
Brothers Municipal Bond Index or Bond Buyer's Index of 25 Revenue Securities or
with the Consumer Price Index, Standard & Poor's, NASDAQ, or other appropriate
indices of investment securities, or with investment or savings vehicles. The
performance information may also include evaluations of the Fund published by
nationally recognized ranking services and by financial publications that are
nationally recognized, such as Business Week, Forbes, Fortune, Institutional
Investor, Investor's Business Daily, Kiplinger's Personal Finance Magazine,
Money, Mutual Fund Forecaster, Stanger's Investment Advisor, USA Today, U.S.
News & World Report, and The Wall Street Journal. Such comparative performance
information will be stated in the same terms in which the comparative data or
indices are stated. 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. For
these purposes, the performance of the Fund, as well as the performance of other
mutual funds or indices, do not reflect sales charges, the inclusion of which
would reduce Fund performance. The Fund will include performance data for Class
A, Class B and Class C shares of the Fund in any advertisement or information
including performance data of the Fund.
    
 
  The Fund may also utilize performance information in hypothetical
illustrations provided in narrative form. These hypotheticals will be
accompanied by the standard performance information required by the SEC as
described above.
 
  The Fund's Annual Report contains additional performance information. A copy
of the Annual Report may be obtained without charge by calling or writing the
Fund at the telephone number and address printed on the cover page of this
Prospectus.

DESCRIPTION OF SHARES OF THE FUND
- ------------------------------------------------------------------------------
 
  The Fund was originally incorporated in Texas on September 8, 1976. The Fund
was incorporated in the State of Maryland on July 2, 1992 and reorganized on
July 31, 1995, under the laws of the state of Delaware as a business entity
commonly known as a "Delaware business trust." It is authorized to issue an
unlimited number of Class A, Class B and Class C shares of beneficial interest
of $0.01 par value. Other classes of shares may be established from time to time
in accordance with provisions of the Fund's Declaration of Trust. Shares issued
by the Fund are fully paid, non-assessable and have no preemptive or conversion
rights.
 
                                       49
<PAGE>   50
 
   
  The Fund currently offers 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 generally are identical in all respects except that
each class bears certain distribution expenses and has exclusive voting rights
with respect to its distribution fee. See "Distribution Plans."
    
 
   
  The Fund is permitted to issue an unlimited number of classes. Each class of
shares is equal as to earnings, assets and voting privileges, except as noted
above, and each class bears the expenses related to the distribution of its
shares. There are no conversion, preemptive or other subscription rights, except
with respect to the conversion of Class B shares and Class C shares into Class A
shares as described above. In the event of liquidation, each of the shares of
the Fund is entitled to its portion of all of the Fund's net assets after all
debt and expenses of the Fund have been paid. Since Class B shares and Class C
shares pay higher distribution expenses, the liquidation proceeds to Class B
shareholders and Class C shareholders are likely to be lower than to other
shareholders.
    
 
  The Fund does not contemplate holding regular meetings of shareholders to
elect Trustees or otherwise. More detailed information concerning the Fund is
set forth in the Statement of Additional Information.
 
  The Fund's Declaration of Trust provides that no Trustee, officer or
shareholder of the Fund shall be held to any personal liability, nor shall
resort be had to their private property for the satisfaction of any obligation
or liability of the Fund but the assets of the Fund only shall be liable.

MUNICIPAL BONDS
 
     "Municipal Bonds" include debt obligations issued to obtain funds for
various public purposes, including construction of a wide range of public
facilities, refunding of outstanding obligations and obtaining funds for general
operating expenses and loans to other public institutions and facilities. In
addition, certain types of industrial development obligations are issued by or
on behalf of public authorities to finance various privately-operated
facilities. Such obligations are included within the term Municipal Bonds if the
interest paid thereon is exempt from Federal income tax. Municipal Bonds also
include short-term tax-exempt municipal obligations such as tax anticipation
notes, bond anticipation notes, revenue anticipation notes, and variable rate
demand notes.
 
     The two principal classifications of Municipal Bonds are "general
obligations" and "revenue" or "special obligations." General obligations are
secured by the issuer's pledge of full faith, credit, and taxing power for the
payment of principal and interest. Revenue or special obligations 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 from other
specific revenue sources such as the user of the facility being financed.
Industrial
 
                                        2
<PAGE>   55
 
development bonds, including pollution control bonds, are revenue bonds and do
not constitute the pledge of the credit or taxing power of the issuer of such
bonds. The payment of the principal and interest on such industrial revenue
bonds depends solely on the ability of the user of the facilities financed by
the bonds to meet its financial obligations and the pledge, if any, of real and
personal property so financed as security for such payment. The Fund's portfolio
may also include "moral obligation" bonds which are normally issued by special
purpose public authorities. If an issuer of moral obligation bonds is unable to
meet its obligations, the repayment of such bonds becomes a moral commitment but
not a legal obligation of the state or municipality which is the issuer of the
bonds.
 
     When the Fund engages in when-issued and delayed delivery transactions, the
Fund relies on the buyer or seller, as the case may be, to consummate the trade.
Failure of the buyer or seller to do so may result in the Fund missing the
opportunity of obtaining a price considered to be advantageous.
 
     The Fund may invest in Municipal Notes which include demand notes and
short-term municipal obligations (such as tax anticipation notes, revenue
anticipation notes, construction loan notes and short-term discount notes) and
tax-exempt commercial paper, provided that such obligations have the ratings
described in the Prospectus. Demand notes are obligations which normally have a
stated maturity in excess of one year, but permit any holder to demand payment
of principal plus accrued interest upon a specified number of days' notice.
Frequently, such obligations are secured by letters of credit or other credit
support arrangements provided by banks. The issuer of such notes normally has a
corresponding right, after a given period, to prepay at its discretion the
outstanding principal of the note plus accrued interest upon a specified number
of days' notice to the noteholders. The interest rate on a demand note may be
based on a known lending rate, such as a bank's prime rate, and may be adjusted
when such rate changes, or the interest rate on a demand note may be a market
rate that is adjusted at specified intervals. Participation interests in
variable rate demand notes will be purchased only if, in the opinion of counsel,
interest income on such interest will be tax-exempt when distributed as
dividends to shareholders.
 
     Yields on Municipal Bonds are dependent on a variety of factors, including
the general condition of the money market and of the municipal bond market, the
size of a particular offering, the maturity of the obligation, and the rating of
the issue. The ability of the Fund to achieve its investment objective is also
dependent on the continuing ability of the issuers of the Municipal Bonds in
which the Fund invests to meet their obligations for the payment of interest and
principal when due. There are variations in the risks involved in holding
Municipal Bonds, both within a particular classification and among
classifications, depending on numerous factors. Furthermore, the rights of
holders of Municipal Bonds and the obligations of the issuers of such Municipal
Bonds may be subject to applicable bankruptcy, insolvency and similar laws and
court decisions affecting the rights of creditors generally, and such laws, if
any, which may be enacted by Congress or state legislatures imposing a
moratorium on the payment of principal and interest or imposing other
constraints or conditions on the payments of principal and interest on Municipal
Bonds.
 
RISK FACTORS RELATING TO HIGH YIELD BONDS
 
     As described in the Prospectus, the Fund may purchase Municipal Bonds rated
BB or B by Standard & Poor's Corporation ("S&P") and Ba or B by Moody's
Investors Services, Inc. ("Moody's") and non-rated securities considered by the
Adviser to be of comparable quality if the purchase would not cause more than
20% of the Fund's total assets to be invested in such lower rated securities.
See the Appendix for a description of Municipal Bond ratings. The Prospectus
discussion of the risks of investing in such lower rated high yield bonds is
supplemented as follows:
 
     1. Youth and Growth of the High Yield Bond Market.  Since the high yield
        bond market is relatively new, its growth has paralleled a long economic
        expansion, and it has not weathered a recession in its present size and
        form. An economic downturn or increase in interest rates is likely to
        have a negative effect on the high yield bond market and on the value of
        the high yield bonds in the Fund's portfolio, as well as on the ability
        of the bonds' issuers to repay principal and interest.
 
     2. Sensitivity to Interest Rate and Economic Changes.  The economy and
        interest rates affect high yield securities differently from other
        securities. The prices of high yield bonds have been found to be less
 
                                        3
<PAGE>   56
 
        sensitive to interest rate changes than higher-rated investments, but
        more sensitive to adverse economic changes or individual issuer
        developments. During an economic downturn or substantial period of
        rising interest rates, the issuers may experience financial stress which
        would adversely affect their ability to service their principal and
        interest obligations, to meet projected revenue goals, and to obtain
        additional financing. If the issuer of a bond owned by the Fund
        defaults, the Fund may incur additional expenses to seek recovery. In
        addition, periods of economic uncertainty and changes can be expected to
        result in increased volatility of market prices of high yield bonds and
        the Fund's asset value. Furthermore, in the case of high yield bonds
        structured as zero coupon or pay-in-kind securities, their market prices
        are affected to a greater extent by interest rate changes and thereby
        tend to be more volatile than securities which pay interest periodically
        and in cash.
 
     3. Liquidity and Valuation.  To the extent that there is no established
        retail secondary market, there may be thin trading of high yield bonds,
        and there may be a negative impact on the Fund's board of directors'
        ability to accurately value high yield bonds and the Fund's assets and
        on the Fund's ability to dispose of the bonds. Adverse publicity and
        investor perceptions, whether or not based on fundamental analysis, may
        decrease the values and liquidity of high yield bonds, especially in a
        thinly traded market. To the extent the Fund owns or may acquire
        illiquid high yield bonds, these securities may involve special
        liquidity and valuation difficulties.
 
     4. Credit Ratings.  Certain risks are associated with applying credit
        ratings as a method of evaluating high yield bonds. Credit ratings
        evaluate the safety of principal and interest payments, not market value
        risk of high yield bonds. Since credit rating agencies may fail to
        timely change the credit ratings to reflect subsequent events, the
        Adviser monitors the issuers of high yield bonds in the Fund's portfolio
        to determine if the issuers appear to have sufficient cash flow to meet
        required principal and interest payments, and to attempt to assure the
        bonds' liquidity so the Fund can meet redemption requests. The Fund may
        retain a portfolio security whose rating has been changed.
 
TEMPORARY INVESTMENTS
 
     The taxable securities in which the Fund may invest as temporary
investments include U.S. Government securities, domestic bank certificates of
deposit and repurchase agreements.
 
     U.S. Government securities include obligations issued or guaranteed as to
principal and interest by the U.S. Government, its agencies and
instrumentalities which are supported by any of the following: (a) the full
faith and credit of the U.S. Government, (b) the right of the issuer to borrow
an amount limited to a specific line or credit from the U.S. Government, (c)
discretionary authority of the U.S. Government agency or instrumentality, or (d)
the credit of the instrumentality. Such agencies or instrumentalities include,
but are not limited to, the Federal National Mortgage Association, the
Government National Mortgage Association, Federal Land Banks, and the Farmer's
Home Administration. The Fund may not invest in a certificate of deposit issued
by a commercial bank unless the bank is organized and operating in the United
States and has total assets of at least $500 million and is a member of the
Federal Deposit Insurance Corporation.
 
REPURCHASE AGREEMENTS
 
     The Fund may enter into repurchase agreements with domestic banks or
broker-dealers. A repurchase agreement is a short-term investment in which the
purchaser (i.e., the Fund) acquires ownership of a debt security and the seller
agrees to repurchase the obligation at a future time and set price, usually not
more than seven days from the date of purchase, thereby determining the yield
during the purchaser's holding period. Repurchase agreements are collateralized
by the underlying debt securities and may be considered to be loans under the
Investment Company Act of 1940, as amended (the "1940 Act"). The Fund will make
payment for such securities only upon physical delivery or evidence of book
entry transfer to the account of a custodian or bank acting as agent. The seller
under a repurchase agreement will be required to maintain the value of the
underlying securities marked to market daily at not less than the repurchase
price. The underlying securities (normally securities of the U.S. Government, or
its agencies and instrumentalities), may have maturity dates exceeding one year.
The Fund does not bear the risk of a decline in value of the underlying security
unless the

seller defaults under its repurchase obligation. See "Investment
Practices -- Repurchase Agreements" in Prospectus for further information.
    
 
FUTURES CONTRACTS AND RELATED OPTIONS
 
FUTURES CONTRACTS
 
     A municipal bond futures contract is an agreement pursuant to which two
parties agree to take and make delivery of an amount of cash equal to a
specified dollar amount times the differences between The Bond Buyer Municipal
Bond Index (the "Index") value at the close of the last trading day of the
contract and the price at which the futures contract is originally struck. The
Index is a price weighted measure of the market value of 40 large sized, recent
issues of tax-exempt bonds.
 
     An interest rate futures contract is an agreement pursuant to which a party
agrees to take or make delivery of a specified debt security (such as U.S.
Treasury bonds or notes) at a specified future time and at a specified price.
 
     Initial and Variation Margin.  In contrast to the purchase or sale of a
security, no price is paid or received upon the purchase or sale of a futures
contract. Initially, the Fund is required to deposit with its Custodian in an
account in the broker's name an amount of cash, cash equivalents or liquid high
grade debt securities equal to not more than five percent of the contract
amount. This amount is known as initial margin. The nature of initial margin in
futures transactions is different from that of margin in securities transactions
in that futures contract margin does not involve the borrowing of funds by the
customer to finance the transaction. Rather, the initial margin is in the nature
of a performance bond or good faith deposit on the contract, which is returned
to the Fund upon termination of the futures contact and satisfaction of its
contractual obligations. Subsequent payments to and from the broker, called
variation margin, are made on a daily basis as the price of the underlying
securities or index fluctuates, making the long and short positions in the
futures contract more or less valuable, a process known as marking to market.
 
     For example, when the Fund purchases a futures contract and the price of
the underlying security or index rises, that position increases in value, and
the Fund receives from the broker a variation margin payment equal to that
increase in value. Conversely, where the Fund purchases a futures contract and
the value of the underlying security or index declines, the position is less
valuable, and the Fund is required to make a variation margin payment to the
broker.
 
     At any time prior to expiration of the futures contract, the Fund may elect
to terminate the position by taking an opposite position. A final determination
of variation margin is then made, additional cash is required to be paid by or
released to the Fund, and the Fund realizes a loss or a gain.
 
     Futures Strategies.  When the Fund anticipates a significant market or
market sector advance, the purchase of a futures contract affords a hedge
against not participating in the advance at a time when the Fund is not fully
invested ("anticipatory hedge"). Such purchase of a futures contract serves as a
temporary substitute for the purchase of individual securities, which may be
purchased in an orderly fashion once the market has stabilized. As individual
securities are purchased, an equivalent amount of futures contracts could be
terminated by offsetting sales. The Fund may sell futures contracts in
anticipation of or in a general market or market sector decline that may
adversely affect the market value of the Fund's securities ("defensive hedge").
To the extent that the Fund's portfolio of securities changes in value in
correlation with the underlying security or index, the sale of futures contracts
substantially reduces the risk to the Fund of a market decline and, by so doing,
provides an alternative to the liquidation of securities positions in the Fund
with attendant transaction costs.
 
     In the event of the bankruptcy of a broker through which the Fund engages
in transactions in futures or related options, the Fund could experience delays
and/or losses in liquidating open positions purchased and/or incur a loss of all
or part of its margin deposits with the broker. Transactions are entered into by
the Fund only with brokers or financial institutions deemed creditworthy by the
Adviser.
 
                                        5
<PAGE>   58
 
     Special Risks Associated with Futures Transactions.  There are several
risks connected with the use of futures contracts as a hedging device. These
include the risk of imperfect correlation between movements in the price of the
futures contracts and of the underlying securities, the risk of market
distortion, the illiquidity risk and the risk of error in anticipating price
movement.
 
     There may be an imperfect correlation (or no correlation) between movements
in the price of the futures contracts and of the securities being hedged. The
risk of imperfect correlation increases as the composition of the securities
being hedged diverges from the securities upon which the futures contract is
based. If the price of the futures contract moves less than the price of the
securities being hedged, the hedge will not be fully effective. To compensate
for the imperfect correlation, the Fund could buy or sell futures contracts in a
greater dollar amount than the dollar amount of securities being hedged if the
historical volatility of the securities being hedged is greater than the
historical volatility of the securities underlying the futures contact.
Conversely, the Fund could buy or sell futures contracts in a lesser dollar
amount than the dollar amount of securities being hedged if the historical
volatility of the securities being hedged is less than the historical volatility
of the securities underlying the futures contract. It is also possible that the
value of futures contracts held by the Fund could decline at the same time as
portfolio securities being hedged; if this occurred, the Fund would lose money
on the futures contract in addition to suffering a decline in value in the
portfolio securities being hedged.
 
     There is also the risk that the price of futures contracts may not
correlate perfectly with movements in the securities or index underlying the
futures contract due to certain market distortions. First, all participants in
the futures market are subject to margin depository and maintenance
requirements. Rather than meet additional margin depository requirements,
investors may close futures contracts through offsetting transactions, which
could distort the normal relationship between the futures market and the
securities or index underlying the futures contract. Second, from the point of
view of speculators, the deposit requirements in the futures market are less
onerous than margin requirements in the securities markets. Therefore, increased
participation by speculators in the futures markets may cause temporary price
distortions. Due to the possibility of price distortion in the futures markets
and because of the imperfect correlation between movements in futures contracts
and movements in the securities underlying them, a correct forecast of general
market trends by the Adviser may still not result in a successful hedging
transaction judged over a very short time frame.
 
     There is also the risk that futures markets may not be sufficiently liquid.
Futures contracts may be closed out only on an exchange or board of trade that
provides a market for such futures contracts. Although the Fund intends to
purchase or sell futures only on exchanges and boards of trade where there
appears to be an active secondary market, there can be no assurance that an
active secondary market will exist for any particular contract or at any
particular time. In the event of such illiquidity, it might not be possible to
close a futures position and, in the event of adverse price movements, the Fund
would continue to be required to make daily payments of variation margin. Since
the securities being hedged would not be sold until the related futures contract
is sold, an increase, if any, in the price of the securities may to some extent
offset losses on the related futures contract. In such event, the Fund would
lose the benefit of the appreciation in value of the securities.
 
     Successful use of futures is also subject to the Adviser's ability to
correctly predict the direction of movements in the market. For example, if the
Fund hedges against a decline in the market, and market prices instead advance,
the Fund will lose part or all of the benefit of the increase in value of its
securities holdings because it will have offsetting losses in futures contracts.
In such cases, if the Fund has insufficient cash, it may have to sell portfolio
securities at a time when it is disadvantageous to do so in order to meet the
daily variation margin.
 
     The Fund could engage in transactions involving futures contracts and
related options in accordance with the rules and interpretations of the
Commodity Futures Trading Commission ("CFTC") under which the Fund would be
exempt from registration as a "commodity pool". CFTC regulations require, among
other things, (i) that futures and related options be used solely for bona fide
hedging purposes (or meet certain conditions as specified in CFTC regulations)
and (ii) that the Fund not enter into futures and related options
 
                                        6
<PAGE>   59
 
for which the aggregate initial margin and premiums exceed five percent of the
fair market value of the Fund's assets. In order to minimize leverage in
connection with the purchase of futures contracts by the Fund, an amount of
cash, cash equivalents or liquid high grade debt securities equal to the market
value of the obligation under the futures contracts (less any related margin
deposits) will be maintained in a segregated account with the Custodian.
 
OPTIONS ON FUTURES CONTRACTS
 
     The Fund could also purchase and write options on futures contracts. An
option on a futures contract gives the purchaser the right, in return for the
premium paid, to assume a position in a futures contract (a long position if the
option is a call and a short position if the option is a put), at a specified
exercise price at any time during the option period. As a writer of an option on
a futures contract, the Fund would be subject to initial margin and maintenance
requirements similar to those applicable to futures contracts. In addition, net
option premiums received by the Fund are required to be included in initial
margin deposits. When an option on a futures contract is exercised, delivery of
the futures position is accompanied by cash representing the difference between
the current market price of the futures contract and the exercise price of the
option. The Fund could purchase put options on futures contracts in lieu of, and
for the same purpose as, it could sell a futures contract. The purchase of call
options on futures contracts would be intended to serve the same purpose as the
actual purchase of the futures contract.
 
     Risks of Transactions in Options on Futures Contracts.  In addition to the
risks described above which apply to all options transactions, there are several
special risks relating to options on futures. The Adviser will not purchase
options on futures on any exchange unless in the Adviser's opinion, a liquid
secondary exchange market for such options exists. Compared to the use of
futures, the purchase of options on futures involves less potential risk to the
Fund because the maximum amount at risk is the premium paid for the options
(plus transaction costs). However, there may be circumstances, such as when
there is no movement in the level of the index or in the price of the underlying
security, when the use of an option on a future would result in a loss to the
Fund when the use of a future would not.
 
ADDITIONAL RISKS TO FUTURES CONTRACTS AND RELATED OPTIONS
 
     Each of the Exchanges has established limitations governing the maximum
number of call or put options on the same underlying security or futures
contract (whether or not covered) which may be written by a single investor,
whether acting alone or in concert with other (regardless of whether such
options are written on the same or different Exchanges or are held or written on
one or more accounts or through one or more brokers). Option positions of all
investment companies advised by the Adviser are combined for purposes of these
limits. An Exchange may order the liquidation of positions found to be in
violation of these limits and it may impose other sanctions or restrictions.
These position limits may restrict the number of listed options which the Fund
may write.
 
     Although the Fund intends to enter into futures contracts only if there is
an active market for such contracts, there is no assurance that an active market
will exist for the contracts at any particular time. Most U.S. futures exchanges
and boards of trade limit the amount of fluctuation permitted in futures
contract prices during a single trading day. Once the daily limit has been
reached in a particular contract, no trades may be made that day at a price
beyond that limit. It is possible that futures contract prices would move to the
daily limit for several consecutive trading days with little or no trading,
thereby preventing prompt liquidation of futures positions and subjecting some
futures traders to substantial losses. In such event, and in the event of
adverse price movements, the Fund would be required to make daily cash payments
of variation margin. In such circumstances, an increase in the value of the
portion of the portfolio being hedged, if any, may partially or completely
offset losses on the futures contract. However, as described above, there is no
guarantee that the price of the securities being hedged will, in fact, correlate
with the price movements in a futures contract and thus provide an offset to
losses on the futures contract.

INVESTMENT RESTRICTIONS
 
     The Fund has adopted the following restrictions which, along with its
investment objective, cannot be changed without approval by the holders of a
majority of its outstanding shares. Such majority is defined by the 1940 Act as
the lesser of (i) 67% or more of the voting securities present in person or by
proxy at the meeting, if the holders of more than 50% of the outstanding voting
securities are present or represented by proxy; or (ii) more than 50% of the
outstanding voting securities. The percentage limitations contained in the
restrictions and policies set forth herein apply at the time of purchase of
securities. These restrictions provide that the Fund shall not:
 
      1. Purchase or hold securities of any issuer if any of the Fund's officers
         or directors, or officers or directors of its investment adviser, who
         beneficially own more than 1/2% of the securities of that issuer,
         together own beneficially more than five percent of the securities of
         such issuer.
 
      2. Purchase securities on margin or make short sales, but it may engage in
         transactions in options, futures contracts and related options and make
         margin deposits and payments in connection therewith.
 
      3. Make loans of money or securities to other persons except through the
         purchase of securities in accordance with its investment objective and
         policies.
 
      4. Invest in real estate; commodities or commodities contracts; interests
         in oil, gas, or other mineral exploration or development programs; or
         any security not payable in United States currency (but this shall not
         prevent the Fund from investing in Municipal Bonds or Temporary
         Investments secured by real estate or interests therein or from
         entering into transactions in futures contracts and related options).
 
      5. Engage in the underwriting of securities or invest more than 15% of its
         net assets in securities subject to restrictions on resale or for which
         there is no readily available market. Such securities include
         securities issued in limited placements under which the Fund represents
         that it is purchasing without a view to a public distribution,
         repurchase agreements maturing in more than seven days and securities
         subject to legal or contractual restrictions on resale.
 
      6. Invest in securities other than Municipal Bonds and Temporary
         Investments (as defined in the Prospectus), listed futures contacts
         related to U.S. Government securities, Municipal Bonds or to an index
         of Municipal Bonds, and options on such contracts.
 
      7. Invest more than five percent of its total assets at market value at
         time of purchase in the securities of any one issuer (other than
         obligations of the United States Government or of any instrumentalities
         thereof).
 
      8. Borrow money, except from banks for temporary or emergency purposes,
         such borrowing not to exceed five percent of its total assets at market
         value at the time of borrowing. Any such borrowing may be secured
         provided that not more than ten percent of the total assets at market
         value at the time of pledging may be used as security for such
         borrowings. Notwithstanding the foregoing, the Fund may engage in
         transactions in options, futures contracts and related options,
         segregate or deposit assets to cover or secure options written, and
         make margin deposits and payments in connection with futures contracts
         and related options.
 
      9. Purchase any Municipal Bond rated below Baa by Moody's and below BBB by
         S&P, or which, if non-rated, is in the opinion of the Adviser of
         comparable quality, if immediately after and as a result of such
         purchase such Bonds would constitute more than 20% of the Fund's total
         assets.
 
     10. Purchase any Municipal Bond rated below A by Moody's and S&P, or which
         is non-rated, if immediately after and as a result of such purchase
         such Bonds would constitute more than 50% of the Fund's total assets.
 
     11. Purchase any Municipal Bond rated below B by Moody's and S&P or any
         non-rated Municipal bonds considered by the Adviser to be of comparable
         quality.
 
                                        8
<PAGE>   61
 
     12. Issue senior securities, as defined in the 1940 Act, except that this
         restriction shall not be deemed to prohibit the Fund from (i) making
         and collateralizing any permitted borrowings, (ii) making any permitted
         loans of its portfolio securities, or (iii) entering into repurchase
         agreements, utilizing futures contracts, options on futures contracts
         and other investment strategies and instruments that would be
         considered "senior securities" but for the maintenance by the Fund of a
         segregated account with its custodian or some other form of "cover".
 
     Each state and each political subdivision, agency or instrumentality of
such state, and each multi-state agency of which a state is a member is a
separate "issuer" as that term is used in the Prospectus. The non-government
user of facilities financed by industrial development bonds is also considered
as a separate issuer. If, however, a security is guaranteed by another entity,
securities issued or guaranteed by such guaranteeing entity shall be limited to
ten percent of the value of the Fund's total assets.
 
     Because of the nature of the securities in which the Fund may invest, the
Fund may not invest in voting securities, or invest for the purpose of
exercising control or management, or invest in securities of other investment
companies.

    $4,786; Mr. Rees, $7,466; and Dr. Sisto, $3,037.
    
 
(4) Prior to October 6, 1994, Mr. Woodside's compensation was paid by the
    Adviser. As a result, with respect to the second and fourth columns, $1,650
    and $36,000, respectively, was paid by the Adviser directly.
 
   
(5) Includes the following amounts for which the various Funds were reimbursed

    paid $36,000 directly by the Adviser as discussed in Footnote 4 above).
    
 
     Beginning July 21, 1995, the Fund pays each trustee who is not affiliated
with the Adviser, the Distributor or VKAC an annual retainer of $1,056 and a
meeting fee of $30 per Board meeting plus expenses. No additional fees are paid
for committee meetings or to the chairman of the board. In order to alleviate an
additional expense that might be caused by the new compensation arrangement, the
trustees have approved a reduction in the compensation per trustee and have
agreed to an aggregate annual compensation cap with respect to the combined fund
complex of $84,000 per trustee until December 31, 1996, based upon the net
assets and the number of Van Kampen American Capital funds as of July 21, 1995
(except that Mr. Whalen, who is a trustee of 34 closed-end funds advised by an
affiliate of the Adviser, would receive an additional $119,000 for serving as a
trustee of such funds). In addition, the Adviser has agreed to reimburse the
Fund through December 31, 1996 for any increase in the aggregate trustees'
compensation paid by the Fund over their 1994 fiscal year aggregate
compensation.

financial officer and the personnel operating under his direction. During the
fiscal years ended September 30, 1992, 1993 and 1994, the Adviser received
$1,393,099, $1,615,258 and $1,804,381, respectively, in advisory fees from the
Fund. For such periods the Fund paid $91,361, $120,055 and $115,272,
respectively, for accounting services. A substantial portion of these amounts
was paid to the Adviser or its parent in reimbursement of personnel, office
space, facilities and equipment costs attributable to the provision of
accounting services to the Fund. The services are provided at cost which is
allocated among the investment companies advised by the Adviser. The Fund also
pays shareholder service agency fees, distribution fees, custodian fees, legal
and auditing fees, the costs of reports to shareholders and all other ordinary
expenses not specifically assumed by the Adviser.
 
     Under the Advisory Agreement, the Fund pays to the Adviser as compensation
for the services rendered, facilities furnished, and expenses paid by it a fee
payable monthly computed on average daily net assets of the Fund at an annual
rate of 0.50% of the Funds average net assets.
 
     The average net asset value is determined by taking the average of all of
the determinations of net asset value for each business day during a given
calendar month. Such fee is payable for each calendar month as soon as
practicable after the end of that month. The Adviser agrees to use its best
efforts to recapture tender solicitation fees and exchange offer fees for the
Fund's benefit, and to advise the Trustees of the Fund of any other commissions,
fees, brokerage or similar payments which may be possible under applicable laws
for the Adviser or any other direct or indirect majority owned subsidiary of
VK/AC Holding, Inc. to receive in connection with the Fund's portfolio
transactions or other arrangements which may benefit the Fund.
 
     The Advisory Agreement also provides that, in the event the expenses of the
Fund for any fiscal year exceed the most restrictive expense limitation
applicable in the states where the Fund's shares are qualified for sale, the
compensation due the Adviser for such fiscal year shall be reduced by the amount
of such excess and that, if a reduction in and refund of the advisory fee is
insufficient, the Adviser will pay the Fund monthly an amount sufficient to make
up the deficiency, subject to readjustment during the year. The Advisory
Agreement also provides that the Adviser shall not be liable to the Fund for any
actions or omissions if it acted in good faith without negligence or misconduct.
 
     Currently, the most restrictive applicable limitations are 2  1/2% of the
first $30 million, 2% of the next $70 million, and 1  1/2% of the remaining
average net assets.
 
     The Advisory Agreement may be continued from year to year if specifically
approved at least annually (a)(i) by the Fund's Trustees or (ii) by vote of a
majority of the Fund's outstanding voting securities and (b) by the affirmative
vote of a majority of the Trustees who are not parties to the agreement or
interested persons of any such party by votes cast in person at a meeting called
for such purpose. The Advisory Agreement provides that it shall terminate
automatically if assigned and that it may be terminated without penalty by
either party on 60 days' written notice.
 
DISTRIBUTOR
 
     The Distributor acts as the principal underwriter of the Fund's shares
pursuant to a written agreement (the "Underwriting Agreement"). The Distributor
has the exclusive right to distribute shares of the Fund through affiliated and
unaffiliated dealers. The Distributor's obligation is an agency or "best
efforts" arrangement under which the Distributor is required to take and pay for
only such shares of the Fund as may be sold to the public. The Distributor is
not obligated to sell any stated number of shares. The Distributor bears the
cost of printing (but not typesetting) prospectuses used in connection with this
offering and the cost and expense of supplemental sales literature, promotion
and advertising. The Underwriting Agreement is renewable from year to year if
approved (a) by the Fund's Trustees or by a vote of a majority of the Fund's
 
                                       14
<PAGE>   67
 
outstanding voting securities and (b) by the affirmative vote of a majority of
Trustees who are not parties to the Underwriting Agreement or interested persons
of any party, by votes cast in person at a meeting called for such purpose. The
Underwriting Agreement provides that it will terminate if assigned, and that it
may be terminated without penalty by either party on 60 days' written notice.
 
     During the fiscal years ended September 30, 1992, 1993 and 1994, total
underwriting commissions on the sale of shares of the Fund were $1,079,211,
$1,055,715 and $793,290, respectively. Of such totals, the amount retained by
the Distributor was $32,794, $97,650 and $118,647, respectively. The remainder
was reallowed to dealers. Of such dealer reallowances, $314,982, $197,590 and
$105,378, respectively, was received by Advantage Capital Corporation, an
affiliated dealer of the Distributor.
 
DISTRIBUTION PLANS
 
   
     The Fund adopted a Class A distribution plan, a Class B distribution plan
and a Class C distribution plan (the "Class A Plan," "Class B Plan" and "Class C
Plan," respectively) to permit the Fund directly or indirectly to pay expenses
associated with servicing shareholders and in the case of the Class B Plan and
Class C Plan the distribution of its shares (the Class A Plan, the Class B Plan
and the Class C Plan are sometimes referred to herein collectively as "Plans"
and individually as a "Plan").
    
 
   
     The Trustees have authorized payments by the Fund under the Plans to
reimburse the Distributor for its payments to certain financial institutions
(which may include banks), securities dealers and other industry professionals
(collectively, "Service Organizations") for administration, for servicing Fund
shareholders who are also their clients and/or for distribution. Such payments
are based on an annual percentage of the value of Fund shares held in
shareholder accounts for which such Service Organizations are responsible. With
respect to the Class A Plan, the Distributor intends to make payments thereunder
only to compensate Service Organizations for personal service and/or the
maintenance of shareholder accounts. With respect to the Class B and Class C
Plans, authorized payments by the Fund include payments at an annual rate of up
to 0.25% of the net assets of the shares of the respective class to reimburse
the Distributor for payments for personal service and/or the maintenance of
shareholder accounts. With respect to the Class B Plan, authorized payments by
the Fund also include payments at an annual rate of up to 0.75% of the net
assets of the Class B shares to reimburse the Distributor for (1) commissions
and transaction fees of up to 4% of the purchase price of the Class B shares
purchased by the clients of broker-dealers and other Service Organizations, (2)
out-of-pocket expenses of printing and distributing prospectuses and annual and
semi-annual shareholder reports to other than existing shareholders, (3)
out-of-pocket and overhead expenses for preparing, printing and distributing
advertising material and sales literature, (4) expenses for promotional
incentives to broker-dealers and financial and industry professions, (5)
advertising and promotion expenses, including conducting and organizing sales
seminars, marketing support salaries and bonuses, and travel-related expenses
and (6) interest expense at the three month LIBOR rate plus 1 1/2% compounded
quarterly on the unreimbursed distribution expenses. With respect to the Class C
Plan, authorized payments under the Class C Plan also include payments at an
annual rate of up to 0.75% of the net assets of the Class C shares to reimburse
the Distributor for (1) upfront commissions and transaction fees of up to 0.75%
of the purchase price of Class C shares purchased by the clients of
broker-dealers and other Service Organizations and ongoing commissions and
transaction fees paid to broker-dealers and other Service Organizations in an
amount up to 0.75% of the average daily net assets of the Fund's Class C shares,
(2) out-of-pocket expenses of printing and distributing prospectuses and annual
and semi-annual shareholder reports to other than existing shareholders, (3)
out-of-pocket and overhead expenses for preparing, printing and distributing
advertising material and sales literature, (4) expenses for promotional
incentives to broker-dealers and financial and industry professionals, (5)
advertising and promotion expenses, including conducting and organizing sales
seminars, marketing support salaries and bonuses, and travel-related expenses
and (6) interest expense at the three month LIBOR rate plus 1 1/2% compounded
quarterly on the unreimbursed distribution expenses. Such reimbursements are
subject to the maximum sales charge limits specified by the NASD for asset-based
charges.
    
 
     Banks are currently prohibited under the Glass-Steagall Act from providing
certain underwriting or distribution services. If banking firms were prohibited
from acting in any capacity or providing any of the described services, the
Distributor would consider what action, if any, would be appropriate. The
Distributor
 
                                       15
<PAGE>   68
 
does not believe that termination of a relationship with a bank would result in
any material adverse consequences to the Fund. In addition, state securities
laws on this issue 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.
 
     As required by Rule 12b-1 under the 1940 Act, each Plan and form of
servicing agreement and selling group agreement were approved by the Trustees,
including a majority of the Trustees who are not affiliated persons (as defined
in the 1940 Act) of the Fund and who have no direct or indirect financial
interest in the operation of any of the Plans or in any agreements related to
each Plan ("Independent Trustees"). In approving the Plans in accordance with
the requirements of Rule 12b-1, the Trustees determined that there is a
reasonable likelihood that each Plan will benefit the Fund and its shareholders.
 
     Each Plan requires the Distributor to provide the Trustees at least
quarterly with a written report of the amounts expended pursuant to each Plan
and the purposes for which such expenditures were made. Unless sooner terminated
in accordance with its terms, each Plan will continue in effect for a period of
one year and thereafter will continue in effect so long as such continuance is
specifically approved at least annually by the Trustees, including a majority of
Independent Trustees.
 
     Each Plan may be terminated by vote of a majority of the Independent
Trustees, or by vote of a majority of the outstanding voting shares of the
respective class of the Fund. Any change in any of the Plans that would
materially increase the distribution expenses borne by the Fund requires
shareholder approval, voting separately by class; otherwise, it may be amended
by a majority of the Trustees, including a majority of the Independent Trustees,
by vote cast in person at a meeting called for the purpose of voting upon such
amendment. So long as the Plan is in effect, the selection or nomination of the
Independent Trustees is committed to the discretion of the Independent Trustees.
 
     For the fiscal year ended September 30, 1994, the Fund's aggregate expenses
under the Class A Plan were $686,403 or .21%, of the Fund's average net assets.
Such expenses were paid to reimburse the Distributor for payments made to
Service Organizations for servicing Fund shareholders and administering the
Class A Plan. The offering of Class B shares commenced on September 29, 1992.
For the fiscal year ended September 30, 1994, the Fund's aggregate expenses
under the Class B Plan were $311,708 or 1.00% of the Class B shares' average
daily net assets. Such expenses were paid to reimburse the Distributor for the
following payments: $233,781 for commissions and transaction fees paid to
broker-dealers and other Service Organizations in respect of sales of Class B
shares of the Fund and $77,927 for fees paid to Service Organizations for
servicing Class B shareholders and administering the Class B Plan. For the
fiscal year ended September 30, 1994, the unreimbursed expenses incurred by the
Distributor under the Class B Plan and carried forward were approximately $1.6
million. The offering of Class C shares commenced August 30, 1993. For the
fiscal year ended September 30, 1994, the Fund's aggregate expenses under the
Class C Plan were $54,489 or 1.00% of the Class C shares' average daily net
assets. Such expenses were paid to the Distributor for the following payments:
$40,867 for commissions and transaction fees paid to broker-dealers and other
Service Organizations in respect of Class C shares of the Fund and $13,622 for
fees paid to Service Organizations for servicing Class C shareholders and
administering the Class C Plan. For the fiscal year ended September 30, 1994,
the unreimbursed expenses incurred by the Distributor under the Class C Plan and
carried forward were approximately $130,000.
 
TRANSFER AGENT
 
   
     For the fiscal years ended September 30, 1994, ACCESS, shareholder service
agent and dividend disbursing agent for the Fund, received fees aggregating
$334,826 for these services. These services are provided at cost plus a profit.
    
 
PORTFOLIO TURNOVER
 
     The portfolio turnover rate is calculated by dividing the lesser of
purchases or sales of portfolio securities for a fiscal year by the average
monthly value of the Fund's portfolio securities during such fiscal year.
Securities which mature in one year or less at the time of acquisition are not
included in this computation. The
 
                                       16
<PAGE>   69
 
turnover rate may vary greatly from year to year as well as within a year. The
Fund's portfolio turnover rate for prior years is shown under "Financial
Highlights" in the Prospectus. The annual turnover rate is expected to exceed
100%, which is higher than that of many other investment companies. A 100%
turnover rate would occur if all the Fund's portfolio securities were replaced
during one year. The lower turnover rate during the last fiscal year reflects
the Adviser's investment strategy and the lower volatility of the market for
municipal securities during the period.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
 
     The Adviser is responsible for decisions to buy and sell securities for the
Fund and for the placement of its portfolio business and the negotiation of any
commissions, if any, paid on such transactions. As most transactions made by the
Fund are principal transactions at net prices, the Fund incurs little or no
brokerage costs. Portfolio securities are normally purchased directly from the
issuer or from an underwriter or market maker for the securities. Purchases from
underwriters of portfolio securities include a commission or concession paid by
the issuer to the underwriter and purchases from dealers serving as market
makers include the spread between the bid and asked price. Sales to dealers are
effected at bid prices.
 
     The Adviser is responsible for placing portfolio transactions and does so
in a manner deemed fair and reasonable to the Fund and not according to any
formula. The primary consideration in all portfolio transactions is prompt
execution of orders in an effective manner at the most favorable price. In
selecting broker-dealers and in negotiating commissions, the Adviser considers
the firm's reliability, the quality of its execution services on a continuing
basis and its financial condition. When more than one firm is believed to meet
these criteria, preference may be given to firms which also provide research
services to the Fund or the Adviser. No specific value can be assigned to such
research services which are furnished without cost to the Adviser. The
investment advisory fee is not reduced as a result of the Adviser's receipt of
such research services. Services provided may include (a) furnishing advice as
to the value of securities, the advisability of investing in, purchasing or
selling securities, and the availability of securities or purchasers or sellers
of securities, (b) furnishing analyses and reports concerning issuers,
industries, securities, economic factors and trends, portfolio strategy and the
performance of the accounts and (c) effecting securities transactions and
performing functions incidental thereto (such as clearance, settlement and
custody). Research services furnished by firms through which the Fund effects
its securities transactions may be used by the Adviser in servicing all of its
advisory accounts; not all of such services may be used by the Adviser in
connection with the Fund.
 
     Consistent with the Rules of Fair Practice of the NASD and subject to
seeking best execution and such other policies as the Trustees may determine,
the Adviser may consider sales of shares of the Fund as a factor in the
selection of firms to execute portfolio transactions for the Fund.
 
     The Adviser places portfolio transactions for other advisory accounts
including other investment companies. The Adviser seeks to allocate portfolio
transactions equitably whenever concurrent decisions are made to purchase or
sell securities by the Fund and another advisory account. In some cases, this
procedure could have an adverse effect on the price or the amount of securities
available to the Fund. In making such allocations among the Fund and other
advisory accounts, the main factors considered by the Adviser are the respective
investment objectives, the relative size of portfolio holdings of the same or
comparable securities, the availability of cash for investment, the size of
investment commitments generally held and opinions of the persons responsible
for recommending the investment.
 
     The Adviser's brokerage practices are monitored on a quarterly basis by the
Brokerage Review Committee comprised of Fund Trustees who are not affiliated
persons (as defined in the 1940 Act) of the Adviser. During the fiscal years
ended September 30, 1992, 1993 and 1994, the Fund paid $-0-, $-0- and $4,589,
respectively, in brokerage commissions. The negotiated commission paid to an
affiliated broker on any transaction would be comparable to that payable to a
non-affiliated broker in a similar transaction.
 
                                       17
<PAGE>   70
 
DETERMINATION OF NET ASSET VALUE
 
     The net asset value of Fund shares is computed by dividing the value of all
securities plus other assets, less liabilities, by the number of shares
outstanding. The net asset value of the shares of the Fund is determined once
daily as of the close of trading (currently 4:00 p.m., New York time) each day
the New York Stock Exchange (the "Exchange") is open. The Exchange is currently
closed on weekends and on the following holidays: New Year's Day, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day
and Christmas Day.
 
     The Fund's investments are valued by an independent pricing service
("Service"). When, in the judgment of the Service, quoted bid prices for
investments are readily available and are representative of the bid side of the
market, these investments are valued at such quoted bid prices (as obtained by
the Service from dealers in such securities). Other investments are carried at
fair value as determined by the Service, based on methods which include
consideration of: yields or prices of municipal bonds of comparable quality,
coupon, maturity and type; indications as to values from dealers; and general
market conditions. The Service may employ electronic data processing techniques
and/or a matrix system to determine valuations. Any assets which are not valued
by the Service would be valued at fair value using methods determined in good
faith by the Directors. Expenses and fees, including the management fee are
accrued daily and taken into account for the purpose of determining the net
asset value of Fund shares. Short-term instruments having remaining maturities
of 60 days or less are valued at amortized cost.
 
     The assets belonging to the Class A shares, the Class B shares and the
Class C shares will be invested together in a single portfolio. The net asset
value of each class will be determined separately by subtracting the expenses
and liabilities allocated to that class from the assets belonging to that class
pursuant to an order issued by the Securities and Exchange Commission ("SEC").
 
PURCHASE AND REDEMPTION OF SHARES
 
     The following information supplements that set forth in the Fund's
Prospectus under the heading "Purchase of Shares."
 
PURCHASE OF SHARES
 
     Shares of the Fund are sold in a continuous offering and may be purchased
on any business day through authorized dealers, including Advantage Capital
Corporation.
 
ALTERNATIVE SALES ARRANGEMENTS
 
     The Fund issues three classes of shares: Class A shares are subject to an
initial sales charge; Class B shares and Class C shares are sold at net asset
value and are subject to a contingent deferred sales charge. The three classes
of shares each represent interests in the same portfolio of investments of the
Fund, have the same rights and are identical in all respects, except that Class
B and Class C shares bear the expenses of the deferred sales arrangements, a
higher distribution services fee, and any expenses (including higher transfer
agency costs) resulting from such sales arrangements, and have exclusive voting
rights with respect to the Rule 12b-1 distribution plan pursuant to which the
distribution fee is paid.
 
     During special promotions, the entire sales charge on Class A shares may be
reallowed to dealers, and at such times dealers may be deemed to be underwriters
for purposes of the 1933 Act.
 
INVESTMENTS BY MAIL
 
     A shareholder investment account may be opened by completing the
application included in the Prospectus and forwarding the application, through
the designated dealer, to ACCESS, at P.O. Box 419319, Kansas City, Missouri
64141-6319. The account is opened only upon acceptance of the application by
ACCESS. The minimum initial investment of $500 or more, in the form of a check
payable to the Fund, must accompany the application. This minimum may be waived
by the Distributor for plans involving continuing investments. Subsequent
investments of $25 or more may be mailed directly to ACCESS. All such
 
                                       18
<PAGE>   71
 
investments are made at the public offering price of Fund shares next computed
following receipt of payment by ACCESS. Confirmations of the opening of an
account and of all subsequent transactions in the account are forwarded by
ACCESS to the investor's dealer of record, unless another dealer is designated.
 
     In processing applications and investments, ACCESS acts as agent for the
investor and for the dealer named thereon, and also as agent for the
Distributor, in accordance with the terms of the Prospectus. If ACCESS ceases to
act as such, a successor company named by the Fund will act in the same
capacities so long as the account remains open.
 
CUMULATIVE PURCHASE DISCOUNT
 
     The reduced sales charges reflected in the sales charge table as shown in
the Prospectus apply to purchases of Class A shares of the Fund where the
aggregate investment is $100,000 or more. For purposes of determining
eligibility for volume discounts, spouses and their minor children are treated
as a single fiduciary account. An aggregate investment includes all shares of
the Fund and all shares of certain other participating Van Kampen American
Capital mutual funds described in the Prospectus (the "Participating Funds"),
which have been previously purchased and are still owned, plus the shares being
purchased. The current offering price is used to determine the value of all such
shares. If, for example, an investor has previously purchased and still holds
Class A shares of the Fund and shares of other Participating Funds having a
current offering price of $40,000, and that person purchases $65,000 of
additional Class A shares of the Fund, the sales charge applicable to the
$65,000 purchase would be 3.75% of the offering price. The same reduction is
applicable to purchases under a Letter of Intent as described in the next
paragraph. THE DEALER MUST NOTIFY THE DISTRIBUTOR AT THE TIME AN ORDER IS PLACED
FOR A PURCHASE WHICH WOULD QUALIFY FOR THE REDUCED CHARGE ON THE BASIS OF
PREVIOUS PURCHASES. SIMILAR NOTIFICATION MUST BE MADE IN WRITING WHEN SUCH AN
ORDER IS PLACED BY MAIL. The reduced sales charge will not be applied if such
notification is not furnished at the time of the order. The reduced sales charge
will also not be applied should a review of the records of the Distributor or
ACCESS fail to confirm the investor's representations concerning his holdings.
 
LETTER OF INTENT
 
   
     Purchases of Class A shares of the Participating Funds described above
under "Cumulative Purchase Discount," made pursuant to the Letter of Intent and
the value of all shares of such Participating Funds previously purchased and
still owned are also included in determining the applicable quantity discount. A
Letter of Intent permits an investor to establish a total investment goal to be
achieved by any number of investments over a 13-month period. Each investment
made during the period will receive the reduced sales charge applicable to the
amount represented by the goal as if it were a single investment. Escrowed
shares totaling five percent of the dollar amount of the Letter of Intent are
held by ACCESS in the name of the shareholder. The effective date of a Letter of
Intent may be back-dated up to 90 days in order that any investments made during
this 90-day period, valued at the investor's cost, can become subject to the
Letter of Intent. The Letter of Intent does not obligate the investor to
purchase the indicated amount. In the event the Letter of Intent goal is not
achieved within the 13-month period, the investor is required to pay the
difference between sales charges otherwise applicable to the purchases made
during this period and sales charges actually paid. Such payment may be made
directly to the Distributor or, if not paid, the Distributor will liquidate
sufficient escrow shares to obtain such difference. If the goal is exceeded in
an amount which qualifies for a lower sales charge, a price adjustment is made
by refunding to the investor in shares of the Fund, the amount of excess sales
charge, if any, paid during the 13-month period.
    
 
REDEMPTION OF SHARES
 
     Redemptions are not made on days during which the Exchange is closed,
including those holidays listed under "Determination of Net Asset Value." The
right of redemption may be suspended and the payment therefor may be postponed
for more than seven days during any period when (a) the Exchange is closed for
other than customary weekends or holidays; (b) trading on the Exchange is
restricted; (c) an emergency exists as a result of which disposal by the Fund of
securities owned by it is not reasonably practicable or it is
 
                                       19
<PAGE>   72
 
not reasonably practicable for the Fund to fairly determine the value of its net
assets; or (d) the SEC, by order, so permits.
 
CONTINGENT DEFERRED SALES CHARGE-CLASS A
 
   
     For investments in the amount of $1,000,000 or more of Class A shares of
the Fund ("Qualified Purchaser"), the front-end sales charge will be waived and
a contingent deferred sales charge ("CDSC-Class A") of one percent is imposed in
the event of certain redemptions within one year of the purchase. If a
CDSC-Class A is imposed upon redemption, the amount of the CDSC-Class A will be
equal to the lesser of one percent of the net asset value of the shares at the
time of purchase, or one percent of the net asset value of the shares at the
time of redemption.
    
 
   
     The CDSC-Class A will only be imposed if a Qualified Purchaser redeems an
amount which causes the value of the account to fall below the total dollar
amount of purchase payments made by the Qualified Purchaser without an initial
sales charge during the one-year period prior to the redemption. The CDSC-Class
A will be waived in connection with redemptions by certain Qualified Purchasers
(e.g., in retirement plans qualified under Section 401(a) of the Code and
deferred compensation plans under Section 457 of the Code) required to obtain
funds to pay distributions to beneficiaries pursuant to the terms of the plans.
Such payments include, but are not limited to, death, disability, retirement or
separation from service. No CDSC-Class A will be imposed on exchanges between
funds. For purposes of the CDSC-Class A, when shares of one fund are exchanged
for shares of another fund, the purchase date for the shares of the fund
exchanged into will be assumed to be the date on which shares were purchased in
the fund from which the exchange was made. If the exchanged shares themselves
are acquired through an exchange, the purchase date is assumed to carry over
from the date of the original election to purchase shares subject to a
CDSC-Class A rather than a front-end load sales charge. In determining whether a
CDSC-Class A is payable, it is assumed that shares held the longest are the
first to be redeemed.
    
 
   
     Cumulative Purchase Discounts and Letters of Intent apply to the net asset
value privilege. Also, in order to establish an amount of $1,000,000 or more, a
Qualified Purchaser may aggregate shares of Van Kampen American Capital Reserve
Fund, Van Kampen American Capital Money Market Fund and Van Kampen American
Capital Tax Free Money Fund with shares of certain other participating funds
described as "Participating Funds" in the Prospectus.
    
 
     As described in the Prospectus under "Redemption of Shares," redemptions of
Class B and Class C shares will be subject to a contingent deferred sales
charge.
 
WAIVER OF CLASS B AND CLASS C CONTINGENT DEFERRED SALES CHARGE ("CDSC-CLASS B
AND C")
 
     The CDSC-Class B and C is waived on redemptions of Class B and Class C
shares in the circumstances described below:
 
     (a) Redemption Upon Disability or Death
 
     The Fund will waive the CDSC-Class B and C on redemptions following the
death or disability of a Class B and Class C 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 Distributor
will require satisfactory proof of death or disability before it determines to
waive the CDSC-Class B and C.
 
     In cases of disability or death, the CDSC-Class B and C will be waived
where the decedent or 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-Class B and C applies to a total or
 
                                       20
<PAGE>   73
 
partial redemption, but only to redemptions of shares held at the time of the
death or initial determination of disability.
 
     (b) Redemption in Connection with Certain Distributions from Retirement
Plans
 
     The Fund will waive the CDSC-Class B and C when a total or partial
redemption is made in connection with certain distributions from Retirement
Plans. The charge will be waived upon the tax-free rollover or transfer of
assets to another Retirement Plan invested in one or more of Van Kampen American
Capital Funds; in such event, as described below, the Fund will "tack" the
period for which the original shares were held on to the holding period of the
shares acquired in the transfer or rollover for purposes of determining what, if
any, CDSC-Class B and C is applicable in the event that such acquired shares are
redeemed following the transfer or rollover. The charge also will be waived on
any redemption which results from the return of an excess contribution pursuant
to Section 408(d)(4) or (5) of the Code, the return of excess deferral amounts
pursuant to Code Section 401(k)(8) or 402(g)(2), or from the death or disability
of the employee (see Code Section 72(m)(7) and 72(t)(2)(A)(ii)). In addition,
the charge will be waived on any minimum distribution required to be distributed
in accordance with Code Section 401(a)(9).
 
     The Fund does not intend to waive the CDSC-Class B and C for any
distributions from IRAs or other Retirement Plans not specifically described
above.
 
     (c) Redemption Pursuant to a Fund's Systematic Withdrawal Plan
 
     A shareholder may elect to participate in a systematic withdrawal plan
("Plan") with respect to the shareholder's investment in the Fund. Under the
Plan, a dollar amount of a participating shareholder's investment in the Fund
will be redeemed systematically by the Fund on a periodic basis, and the
proceeds mailed to the shareholder. The amount to be redeemed and frequency of
the systematic withdrawals will be specified by the shareholder upon his or her
election to participate in the Plan. The CDSC-Class B and C will be waived on
redemptions made under the Plan.
 
     The amount of the shareholder's investment in a Fund at the time the
election to participate in the Plan is made with respect to the Fund is
hereinafter referred to as the "initial account balance." The amount to be
systematically redeemed from such Fund without the imposition of a CDSC-Class B
and C may not exceed a maximum of 12% annually of the shareholder's initial
account balance. The Fund reserves the right to change the terms and conditions
of the Plan and the ability to offer the Plan.
 
     (d) Involuntary Redemptions of Shares in Accounts that Do Not Have the
         Required Minimum Balance
 
     The Fund reserves the right to redeem shareholder accounts with balances of
less than a specified dollar amount as set forth in the Prospectus. Prior to
such redemptions, shareholders will be notified in writing and allowed a
specified period of time to purchase additional shares to bring the account up
to the required minimum balance. The Fund will waive the CDSC upon such
involuntary redemption.
 
     (e) Reinvestment of Redemption Proceeds in Shares of the Same Fund Within
         120 Days After Redemption
 
     A shareholder who has redeemed Class C shares of a Fund may reinvest, with
credit for any CDSC-Class C paid on the redeemed shares, any portion or all of
his or her redemption proceeds (plus that amount necessary to acquire a
fractional share to round off his or her purchase to the nearest full share) in
shares of the Fund, provided that the reinvestment is effected within 120 days
after such redemption and the shareholder has not previously exercised this
reinvestment privilege with respect to Class C shares of the Fund. Shares
acquired in this manner will be deemed to have the original cost and purchase
date of the redeemed shares for purposes of applying the CDSC-Class C to
subsequent redemptions.
 
     (f) Redemption by Adviser
 
     The Fund may waive the CDSC-Class B and C when a total or partial
redemption is made by the Adviser with respect to its investments in the Fund.
 
                                       21

EXCHANGE PRIVILEGE
 
     The following supplements the discussion of "Shareholder
Services -- Exchange Privilege" in the Prospectus:
 
     By use of the exchange privilege, the investor authorizes ACCESS to act on
telephonic, telegraphic or written exchange instructions from any person
representing himself to be the investor or the agent of the investor and
believed by ACCESS to be genuine. VKAC and its subsidiaries, including ACCESS
(collectively, "Van Kampen American Capital"), and the Fund employ procedures
considered by them to be reasonable to confirm that instructions communicated by
telephone are genuine. Such procedures include requiring certain personal
identification information prior to acting upon telephone instructions, tape
recording telephone communications, and providing written confirmation of
instructions communicated by telephone. If reasonable procedures are employed,
neither Van Kampen American Capital nor the Fund will be liable for following
telephone instructions which it reasonably believes to be genuine. Van Kampen
American Capital and the Fund may be liable for any losses due to unauthorized
or fraudulent instructions if reasonable procedures are not followed.
 
     For purposes of determining the sales charge rate previously paid on Class
A shares, all sales charges paid on the exchanged security and on any security
previously exchanged for such security or for any of its predecessors shall be
included. If the exchanged security was acquired through reinvestment, that
security is deemed to have been sold with a sales charge rate equal to the rate
previously paid on the security on which the dividend or distribution was paid.
If a shareholder exchanges less than all of his securities, the security upon
which the highest sales charge rate was previously paid is deemed exchanged
first.
 
     Exchange requests received on a business day prior to the time shares of
the funds involved in the request are priced will be processed on the date of
receipt. "Processing" a request means that shares in the fund from which the
shareholder is withdrawing an investment will be redeemed at the net asset value
per share next determined on the date of receipt. Shares of the new fund into
which the shareholder is investing will also normally be purchased at the net
asset value per share, plus any applicable sales charge, next determined on the
date of receipt. Exchange requests received on a business day after the time
shares of the funds involved in the request are priced will be processed on the
next business day in the manner described herein.
 
     A prospectus of any of these mutual funds may be obtained from any
authorized dealer or the Distributor. An investor considering an exchange to one
of such funds should refer to the prospectus for additional information
regarding such fund.
 
CHECK WRITING PRIVILEGE
 
     To establish the check writing privilege for Class A shares, a shareholder
must complete the appropriate section of the application and the Authorization
for Redemption form to ACCESS before checks will be issued. All signatures on
the authorization card must be guaranteed if any of the signators are persons
not referenced in the account registration or if more than 30 days have elapsed
since ACCESS established the account on its records. Moreover, if the
shareholder is a corporation, partnership, trust, fiduciary, executor or
administrator, the appropriate documents appointing authorized signers
(corporate resolutions, partnerships or trust agreements) must accompany the
authorization card. The documents must be certified in original form, and the
certificates must be dated within 60 days of their receipt by ACCESS.
 
     The privilege does not carry over to accounts established through exchanges
or transfers. It must be requested separately for each fund account.
 
FEDERAL TAX INFORMATION
 
     The following is only a summary of certain additional federal tax
considerations generally affecting the Fund and its shareholders that are not
described in the Prospectus. No attempt is made to present a detailed
explanation of the tax treatment of the Fund or its shareholders, and the
discussion here and in the Prospectus is not intended as a substitute for
careful tax planning. Investors are urged to consult their tax advisers with
specific reference to their own tax situation.
 
                                       22
<PAGE>   75
 
     The Fund has elected to be taxed as a regulated investment company under
Sections 851-855 of the Code. This means the Fund must pay all or substantially
all its taxable net investment income and taxable net realized capital gains to
shareholders of Class A, Class B and Class C shares and meet certain
diversification and other requirements. The per share dividends on Class B and
Class C shares will be lower than the per share dividends on Class A shares as a
result of the higher distribution services and incremental transfer agency fees
applicable to the Class B and Class C shares. By qualifying as a regulated
investment company, the Fund is not subject to federal income taxes to the
extent it distributes its taxable net investment income and taxable net realized
capital gains. If for any taxable year the Fund does not qualify for the special
tax treatment afforded regulated investment companies, all of its taxable
income, including any net realized capital gains, would be subject to tax at
regular corporate rates (without any deduction for distributions to
shareholders).
 
     If shares of the Fund are sold or exchanged within 90 days of acquisition,
and shares of the same or a related mutual fund are acquired, to the extent the
sales charge is reduced or waived on the subsequent acquisition, the sales
charge may not be used to determine the basis in the disposed shares for
purposes of determining gain or loss. To the extent the sales charge is not
allowed in determining gain or loss on the initial shares, it is capitalized in
the basis of the subsequent shares.
 
     The Code permits a regulated investment company whose assets consist
primarily of tax-exempt Municipal Bonds to pass through to its investors,
tax-exempt, net Municipal Bond interest income. In order for the Fund to be
eligible to pay exempt-interest dividends during any taxable year, at the close
of each fiscal quarter, at least 50% of the aggregate value of the Fund's assets
must consist of exempt-interest obligations. In addition, the Fund must
distribute at least (i) 90% of the excess of its exempt-interest income over
certain disallowed deductions, and (ii) 90% of its "investment company taxable
net income" (i.e., its ordinary taxable income and the excess, if any, of its
net short-term capital gains over any net long-term capital losses) recognized
by the Fund during the taxable year (the "Distribution Requirements").
 
     The Fund is subject to a four percent excise tax to the extent it fails to
distribute to its shareholders at least 98% of its ordinary taxable (net
investment) income for the twelve months ended December 31, plus 98% of its
capital gain net income for the twelve months ended October 31 of such calendar
year. The Fund intends to distribute sufficient amounts to avoid liability for
the excise tax.
 
     Not later than 60 days after the close of its taxable year, the Fund will
notify its shareholders of the portion of the dividends paid by the Fund to the
shareholders for the taxable year which constitutes exempt-interest dividends.
The aggregate amount of dividends so designated cannot exceed, however, the
amount of interest exempt from tax under Section 103 of the Code received by the
Fund during the year over any amounts disallowed as deductions under Sections
265 and 171(a)(2) of the Code. Since the percentage of dividends which are
"exempt-interest" dividends is determined on an average annual method for the
fiscal year, the percentage of income designated as tax-exempt for any
particular dividend may be substantially different from the percentage of the
Fund's income that was tax-exempt during the period covered by the dividend.
 
     Although exempt-interest dividends generally may be treated by the Fund's
shareholders as items of interest excluded from their gross income, each
shareholder is advised to consult his tax adviser with respect to whether
exempt-interest dividends retain this exclusion if the shareholder would be
treated as a "substantial user" or a "related person" with respect to any of the
tax-exempt obligations held by the Fund. "Substantial user" is defined under
U.S. Treasury Regulations to include a non-exempt person who regularly uses in
his trade or business a part of any facilities financed with the tax-exempt
obligations and whose gross revenues derived from such facilities exceed five
percent of the total revenues derived from the facilities by all users, or who
occupies more than five percent of the usable area of the facilities or for whom
the facilities or a part thereof were specifically constructed, reconstructed or
acquired. Examples of "related persons" include certain related natural persons,
affiliated corporations, a partnership and its partners and an S corporation and
its shareholders.
 
     Interest on indebtedness incurred by a shareholder to purchase or carry
shares of the Fund is not deductible for federal income tax purposes if the Fund
distributes exempt-interest dividends during the
 
                                       23
<PAGE>   76
 
shareholder's taxable year. If a shareholder receives an exempt-interest
dividend with respect to any shares and such shares are held for six months or
less, any short-term capital loss on the sale or exchange of the shares will be
disallowed to the extent of the amount of such exempt-interest dividend.
 
     If, during any taxable year, the Fund realizes net capital gains (the
excess of net long-term capital gains over net short-term capital losses) from
the sale or other disposition of Municipal Bonds or other assets, the Fund will
have no tax liability with respect to such gains if they are distributed to
shareholders. Distributions designated as capital gains dividends are taxable to
shareholders as long-term capital gains, regardless of how long a shareholder
has held his shares. Not later than 60 days after the close of the Fund's
taxable year, the Fund will send to its shareholders a written notice
designating the amount of any distributions made during the year which
constitute capital gain.
 
     A capital gain dividend received after the purchase of the Fund's shares
reduces the net asset value of the shares by the amount of the distribution and
will be subject to income taxes. A loss on the sale of shares held for less than
six months (to the extent not disallowed on account of the receipt of
exempt-interest dividends) attributable to a capital gain dividend is treated as
a long-term capital loss for Federal income tax purposes.
 
     Dividends to shareholders who are non-resident aliens may be subject to a
United States withholding tax at a rate of up to 30% under existing provisions
of the Code applicable to foreign individuals and entities unless a reduced rate
of withholding or a withholding exemption is provided under applicable treaty
law. Non-resident shareholders are urged to consult their own tax adviser
concerning the applicability of the United States withholding tax.
 
BACK-UP WITHHOLDING
 
     The Fund is required to withhold and remit to the United States Treasury
31% of (i) reportable taxable dividends and distributions and (ii) the proceeds
of any redemptions of Fund shares with respect to any shareholder who is not
exempt from withholding and who fails to furnish the Fund with a correct
taxpayer identification number, who fails to report fully dividend or interest
income or who fails to certify to the Fund that he has provided a correct
taxpayer identification number and that he is not subject to withholding. (An
individual's taxpayer identification number is his social security number.) The
31% "back-up withholding tax" is not an additional tax and may be credited
against a taxpayer's regular federal income tax liability.
 
TREATMENT OF DIVIDENDS
 
     While the Fund expects that a major portion of its investment income will
constitute tax-exempt interest, a portion may consist of "investment company
taxable income" and "net capital gains". As pointed out above, the Fund will be
subject to tax for any year on its undistributed investment company taxable
income and net capital gains.
 
     It is anticipated that substantially all of the Fund's taxable income and
capital gain net income will be distributed by the Fund in order to meet the
Distribution Requirements and to avoid taxation at the Fund level. Dividends
from net investment income and distributions from any short-term capital gains
are taxable to shareholders as ordinary income.
 
     Dividends and distributions declared to shareholders of record after
September 30 of any year and paid before February 1 of the following year, are
considered taxable income to shareholders on the record date even though paid in
the next year.
 
     Since none of the Fund's net investment income will arise from dividends on
common or preferred stock, none of its distributions are eligible for the 70%
dividends received deduction for corporations. To qualify for the dividends
received deduction, a corporate shareholder must hold the shares on which the
dividend is paid for more than 45 days.
 
     The Tax Reform Act of 1986 (the "Tax Reform Act") added a provision that,
for taxable years beginning after December 31, 1989, 75% of the excess of a
corporation's adjusted current earnings (generally, earning and profits, with
adjustments) over its other alternative minimum taxable income is an item of tax
 
                                       24
<PAGE>   77
 
preference for corporations. All tax-exempt interest is included in the
definition of "adjusted current earnings" so a portion of such interest is
included in computing the alternative minimum tax on corporations. For
shareholders that are financial institutions, the Tax Reform Act eliminated
their ability to deduct interest payments to the extent allocated on a pro rata
basis to the purchase of Fund shares.
 
     The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury regulations presently in effect. For the
complete provisions, reference should be made to the pertinent Code sections and
the Treasury regulations promulgated thereunder. The Code and these Treasury
regulations are subject to change by legislative or administrative action either
prospectively or retroactively.
 
     Dividends and capital gains distributions may also be subject to state and
local taxes.
 
     Shareholders are urged to consult their attorneys or tax advisers regarding
specific questions as to federal, state or local taxes.
 
TAX TREATMENT OF FUTURES CONTRACTS AND RELATED OPTIONS
 
     In connection with its operations, the Fund may effect transactions in U.S.
Government securities and municipal bond futures contracts ("Futures Contracts")
and in options thereon ("Futures Options"). Gains or losses recognized by the
Fund from transactions in such Futures Contracts and Futures Options constitute
capital gains and losses for federal income tax purposes and do not therefore
qualify as exempt-interest income.
 
     With respect to a Futures Contract closed out by the Fund, any realized
gain or loss will be treated as long-term capital gain or loss to the extent of
60 percent thereof and short-term capital gain or loss to the extent of 40
percent thereof (hereinafter "60/40 gain or loss"). Open Futures Contracts held
by the Fund at the end of any fiscal year will be required to be treated as sold
at market value on the last day of such fiscal year for federal income tax
purposes (i.e. "marked-to-market"). Gain or loss recognized under this mark-to-
market rule is 60/40 gain or loss. The federal income tax treatment accorded to
Futures Options will be the same as that accorded to Futures Contracts. The
Distribution Requirements may limit the Fund's ability to hold Futures Contracts
and Futures Options at the end of a year.
 
     A portion of the Fund's transactions in Futures Contracts and Futures
Options, particularly its hedging transactions, may constitute "straddles" with
respect to the Fund's holdings of Municipal Securities. Straddles are defined in
Section 1092 of the Code as offsetting positions with respect to personal
property. A straddle in which at least one (but not all) of the positions are
Section 1256 contracts is a "mixed straddle" under the Code if certain
identification requirements are met.
 
     The Code generally provides with respect to straddles (i) "loss deferral"
rules which may postpone a recognition for tax purposes of losses from certain
closing purchase transactions or other dispositions of a position in the
straddle to the extent of unrealized gains in the offsetting position, (ii)
"wash sale" rules which may postpone recognition for tax purposes of losses
where a position forming part of a straddle is sold and a new offsetting
position is acquired within a prescribed period, and (iii) "short sale" rules
which may terminate the holding period of securities owned by the Fund when
offsetting positions are established and which may convert certain losses from
short-term to long-term.
 
     The Code provides that certain elections may be made for mixed straddles
that can alter the character of the capital gain or loss recognized upon
disposition of positions which form part of a straddle. Certain other elections
are also provided in the Code. The Fund has not determined whether it will make
any of these elections.
 
     The Fund may acquire an option to "put" specified portfolio securities to
banks or municipal bond dealers from whom the securities are purchased. See
"Stand-By Commitments," in the Prospectus. The Fund has been advised by its
legal counsel that it will be treated for federal income tax purposes as the
owner of the Municipal Securities acquired subject to the put; and the interest
on the Municipal Securities will be tax-exempt to the Fund. Counsel has pointed
out that although the Internal Revenue Service has issued a favorable published
ruling on a similar but not identical situation, it could reach a different
conclusion from
 
                                       25
<PAGE>   78
 
that of counsel. Counsel has also advised the Fund that the Internal Revenue
Service presently will not ordinarily issue private letter rulings regarding the
ownership of securities subject to stand-by commitments.
 
RESTRICTIONS ON FUTURES CONTRACTS AND RELATED OPTIONS
 
     Among the requirements for qualification as a regulated investment company
under the Code, the Fund must derive less than 30% of its gross income each year
from sales of securities held for less than three months. This requirement and
the mark-to-market rule may restrict the Fund's ability to: (i) effect closing
purchase transactions in Futures Contracts and Futures Options which have been
held for less than three months, and (ii) enter into various other short-term
transactions.
 
     In addition, the Code requires that a Fund satisfy certain portfolio
diversification requirements at the end of each fiscal quarter of its taxable
year in order to maintain its qualification as a regulated investment company.
In general, no more than 25% of the value of a Fund's assets may be invested in
the securities of any one issuer and at least 50% of the value of the Fund's
assets must be represented by securities of issuers each of which separately
represents not more than five percent of the value of the total assets of the
Fund. Consequently, a Fund's ability to invest in Futures Contracts and Futures
Options may be limited.
 
   
FUND PERFORMANCE
    
 
     The Fund's average annual total return for Class A shares for the one-year,
five-year and ten-year periods ended March 31 1995, was 1.03%, 6.88% and 8.59%,
respectively. The average annual total return for Class B shares of the Fund for
the one-year period ended March 31, 1995 was 1.14%, and for the period from
September 29, 1992 (the initial offering of Class B shares) to March 31, 1995
was 4.18%. The average annual total return for Class C shares for the one-year
period ended March 31, 1995 was 4.14%, and for the period from August 30, 1993
(the initial offering of Class C shares) to March 31, 1995 was 1.92%. These
results are based on historical earnings and asset value fluctuations and are
not intended to indicate future performance. Such information should be
considered in light of the Fund's investment objective and policies as well as
the risks incurred in the Fund's investment practices.
 
     The annualized current yield for Class A shares, Class B shares and Class C
shares of the Fund for the 30-day period ending March 31, 1995 was 4.98%, 4.39%
and 4.38%, respectively. The tax equivalent yield (based on an assumption of a
tax rate of 36%) for the same period for Class A, Class B and Class C shares of
the Fund was 7.77%, 6.85%, and 6.84%, respectively. The yield for Class A, Class
B and Class C shares is not fixed and will fluctuate in response to prevailing
interest rates and the market value of portfolio securities, and as a function
of the type of securities owned by the Fund, portfolio maturity and the Fund's
expenses.
 
     Yield and total return are computed separately for Class A, Class B and
Class C shares.
 
   
     From time to time, in reports or other communications, or in advertising or
sales materials, the Adviser may announce the results of actual tests performed
by DALBAR Financial Securities, Inc., an independent research firm, as they
relate to the level of services for mutual fund investors and may refer to the
Missouri Quality Award received by ACCESS, the Fund's transfer agent, in 1993.
In addition, the Adviser may also refer to the Houston Awards for Quality
received by Van Kampen American Capital in 1994.
    
 
     From time to time, VKAC will announce the results of its monthly polls of
U.S. investor intentions -- the Van Kampen American Capital Index of Investor
IntentionsSM and the Van Kampen American Capital Mutual Fund IndexSM -- which
polls measure how Americans plan to use their money.
 
     The Fund may, from time to time: (1) illustrate the benefits of
tax-deferral by comparing taxable investments to investments made through
tax-deferred retirement plans; (2) illustrate in graph or chart form, or
otherwise, the benefits of dollar cost averaging by comparing investments made
pursuant to a systematic investment plan to investments made in a rising market;
(3) illustrate allocations among different types of mutual funds for investors
at different stages of their lives; and (4) in reports or other communications
to shareholders or in advertising material, illustrate the benefits of
compounding at various assumed rates of return. Such illustrations may be in the
form of charts or graphs and will not be based on historical returns experienced
by the Fund.

                             RATINGS OF INVESTMENTS
 
Ratings of Municipal Bonds
Descriptions of Moody's Investors Service, Inc. ("Moody's") Municipal Bond
Ratings:
 
     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 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.
 
     Conditional Rating: Bonds for which the security depends upon the
completion of some act or the fulfillment of some condition are rated
conditionally. These are bonds secured by (a) earnings of projects under
construction, (b) earnings of projects unseasoned in operation experience, (c)
rentals which begin when facilities are completed, or (d) payments to which some
other limiting condition attaches. Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.
 
     Rating Refinements: Moody's may apply numerical modifiers, 1, 2 and 3 in
each generic rating classification from Aa through B in its municipal bond
rating system. The modifier 1 indicates that the security ranks in the higher
end of its generic rating category; the modifier 2 indicates a midrange ranking;
and a modifier 3 indicates that the issue ranks in the lower end of its generic
rating category.
 
     Short-term Notes: The four ratings of Moody's for short-term notes are MIG
1, MIG 2, MIG 3 and MIG 4; MIG 1 denotes "best quality, enjoying strong
protection from established cash flows"; MIG 2 denotes "high quality" with
"ample margins of protection"; MIG 3 notes are of "favorable quality . . . but
lacking the undeniable strength of the preceding grades"; MIG 4 notes are of
"adequate quality, carrying specific risk but having protection . . . and not
distinctly or predominantly speculative."
 
     Beginning on February 5, 1985, Moody's started new rating categories for
variable rate demand obligations ("VRDO's"). VRDO's receive two ratings. The
first rating, depending on the maturity of the VRDO, is assigned either a bond
or MIG rating which represents an evaluation of the risk associated with
scheduled principal and interest payments. The second rating, designated as
"VMIG," represents an
 
                                       28
<PAGE>   81
 
evaluation of the degree of risk associated with the demand feature. The new
VRDO's demand feature ratings and symbols are:
 
     VMIG 1: strong protection by established cash flows, superior liquidity
             support, demonstrated access to the market for refinancing.
 
     VMIG 2: ample margins of protection, high quality.
 
     VMIG 3: favorable quality, liquidity and cash flow protection may be
             narrow, market access for refinancing may be less well established.
 
     VMIG 4: adequate quality, not predominantly speculative but there is risk.
 
DESCRIPTIONS OF MOODY'S COMMERCIAL PAPER RATINGS
 
     Moody's Commercial Paper ratings are opinions of the ability of issuers to
repay punctually promissory obligations not having an original maturity in
excess of nine months. Moody's employs three designations, all judged to be
investment grade, to indicate the relative repayment capacity of rated issuers.
The first two are described below:
 
          Issuers rated Prime-1 (or related supporting institutions) have a
     superior capacity for repayment of short-term promissory obligations.
 
          Issuers rated Prime-2 (or related supporting institutions) have a
     strong capacity for repayment of short-term promissory obligations.
 
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S ("S&P") MUNICIPAL DEBT RATINGS
 
     A S&P's 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 S&P 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 for other
reasons.
 
     The ratings are based, in varying degrees, on the following considerations:
 
     I.     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;
 
     II.    Nature of and provisions of the obligation;
 
     III.   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 creditor's rights.
 
     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 they are somewhat more susceptible to the adverse
            effects of changes in circumstances and economic conditions than 
            debt in higher-rated categories.
 
                                       29
<PAGE>   82
 
     BBB   Debt rated "BBB" is regarded as having an adequate capacity to pay
           interest and repay principal. Whereas it normally exhibits adequate
           protection parameters, adverse economic conditions or changing
           circumstances are more likely to lead to a weakened capacity to pay
           interest and repay principal for debt in this category than for debt
           in higher-rated categories.
 
     BB,B  Debt rated "BB" and "B" is regarded, on balance, as predominantly
           speculative with respect to capacity to pay interest and repay
           principal in accordance with the terms of the obligation. "BB"
           indicates the lowest degree of speculation. While such debt will
           likely have some quality and protective characteristics, these are
           outweighed by large uncertainties or major risk exposures to adverse
           conditions.
 
     Plus (+) or Minus (-): The ratings from "AA" to "BB" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
     Provisional Ratings: The letter "p" indicates that the rating is
provisional. A provisional rating assumes the successful completion of the
project being financed by the bonds being rated and indicates that payment of
debt service requirements is largely or entirely dependent upon the successful
and timely completion of the project. This rating, however, while addressing
credit quality subsequent to completion of the project, makes no comment on the
likelihood 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.
 
     NR    Indicates that no 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.
 
     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. The
highest category is "A" which is further defined with the designation of 1, 2
and 3 to indicate the relative degree of safety. The first two categories are
described below:
 
     A     Issues assigned this highest rating are regarded as having the
           greatest capacity for timely payment.
 
     A-1   This designation indicates that the degree of safety regarding timely
           payment is very strong.
 
     A-2   Capacity for timely payment on issues with this designation is
           strong. However, the relative degree of safety is not as overwhelming
           as for issues designated "A-1".
 
     The 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 and 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.
 
     Commencing on July 27, 1984, S&P instituted a new rating category with
respect to certain municipal note issues with a maturity of less than three
years. The new note ratings and symbols are:
 
     SP-1  A very strong, or strong, capacity to pay principal and interest.
           Issues that possess overwhelming safety characteristics will be given
           a "+" designation.
 
     SP-2  A satisfactory capacity to pay principal and interest.
 
     SP-3  A speculative capacity to pay principal and interest.
 
     S&P may continue to rate note issues with a maturity greater than three
years in accordance with the same rating scale currently employed for municipal
bond ratings.
 
     S&P assigns dual ratings to all long-term debt issues that have a demand or
put feature. The first rating addresses the likelihood of repayment of principal
and interest as due, and the second rating addresses the demand feature alone.
Long-term debt rating symbols are used for the long-term maturity and commercial
paper rating symbols are used for the put option (for example, AAA/A-1+). For
demand notes, S&P's note rating symbols are used with the commercial paper
symbols (for example, SP-1+/a-1+).

     Rating criteria described in the Prospectus are applied on the basis of the
highest rating applicable to the Municipal Security. This applies to split rated
securities (i.e., different ratings by Moody's and S&P) and dual rated
securities as described above.
 
     Subsequent to its purchase by the Fund, an issue of Municipal Bonds or a
Temporary Investment may cease to be rated or its rating may be reduced, causing
more than 20% of the Fund's assets invested in Municipal Bonds to be invested in
low or non-rated bonds. This would not require the elimination of such
obligation from the Fund's portfolio, but the Adviser will consider such an
event in its determination of whether the Fund should continue to hold such
obligation in its portfolio. To the extent that the ratings accorded by S&P or
Moody's for Municipal Bonds or Temporary Investment may change as a result of
changes in such organizations, or changes in their rating systems, the Fund will
attempt to use comparable ratings as standards for its investments in Municipal
Bonds or Temporary Investments in accordance with the investment policies
contained herein.

Notes to Financial Statements

Note 1-Significant Accounting Policies
American Capital Municipal Bond Fund (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified open-end
management investment company. The following is a summary of significant
accounting policies consistently followed by the Fund in the preparation of its
financial statements.

A.    Investment Valuations
      Investments in municipal bonds are valued at the most recently quoted bid
      prices or at bid prices based on a matrix system (which considers such
      factors as security prices, yields, maturities and ratings) furnished by
      dealers and an independent pricing service. Municipal variable rate
      demand notes are valued at par; periodic rate changes reflect current
      market conditions.

      Short-term investments with a maturity of 60 days or less when purchased
      are valued at amortized cost, which approximates market value. Short-term
      investments with a maturity of more than 60 days when purchased are
      valued based on market quotations until the remaining days to maturity
      becomes less than 61 days. From such time, until maturity, the
      investments are valued at amortized cost.

      Issuers of certain securities owned by the Fund have obtained insurance
      guaranteeing their timely payment of principal and interest at maturity.
      The insurance reduces financial risk but not market risk of the security.

      Fund investments include lower rated debt securities which may be more
      susceptible to adverse economic conditions than other investment grade
      holdings. These securities are often subordinated to the prior claims of
      other senior lenders and uncertainties exist as to an issuer's ability to
      meet principal and interest payments. At September 30, 1994, debt
      securities rated below investment grade and comparable unrated securities
      represented approximately 19% of the investment portfolio.

B.    Federal Income Taxes
      No provision for federal income taxes is required because the Fund has
      elected to be taxed as a "regulated investment company" under the
      Internal Revenue Code and intends to maintain this qualification by
      annually distributing all of its taxable net investment income and
      taxable net realized capital gains to its shareholders.  It is
      anticipated that no distributions of net realized capital gains will be
      made until tax basis capital loss carryforwards expire or are offset by
      net realized capital gains.

C.    Investment Transactions and Related Investment Income
      Investment transactions are accounted for on the trade date. Realized
      gains and losses on investments are determined on the basis of identified
      cost. Interest income is accrued daily.

D.    Dividends and Distributions
      Dividends and distributions to shareholders are recorded on the record
      date. The Fund distributes tax basis earnings in accordance with the
      minimum distribution requirements of the Internal Revenue Code, which may
      differ from generally accepted accounting principles. Such dividends or
      distributions may exceed financial statement earnings.

E.    Debt Discount and Premium
      The Fund accounts for debt discounts and premiums on the same basis as is
      followed for federal income tax reporting. Accordingly, original issue
      discounts and all premiums are amortized over the life of the security.
      Market discounts are recognized at the time of sale as realized gains for
      book purposes, and ordinary income for tax purposes.

F.    Equalization
      At September 30, 1994, the Fund discontinued the accounting practice of
      equalization, which it had used since its inception. Equalization is a
      practice whereby a portion of the proceeds from sales and costs of
      redemptions of Fund shares, equivalent on a per-share basis to the




                                     F-14
<PAGE>   98

      amount of the undistributed net investment income, is charged or credited
      to undistributed net investment income.

      The balance of equalization included in undistributed net investment
      income at the date of change, which was approximately $2.8 million, was
      reclassified to capital surplus. Such reclassification had no effect on
      net assets, results of operations, or net asset value per share of the
      Fund.

G.    When-Issued Securities
      Delivery and payment for securities purchased on a when-issued basis may
      take place up to 45 days after the date of the transaction. The
      securities purchased are subject to market fluctuation during this
      period. To meet the payment obligation, sufficient cash or liquid
      securities equal to the amount that will be due are set aside with the
      custodian.

Note 2-Management Fees and Other Transactions with Affiliates
American Capital Asset Management, Inc. (the "Adviser") serves as investment
manager of the Fund. Management fees are paid monthly, based on the rate of
 .50% per annum of the average daily net assets of the Fund.

Accounting services include the salaries and overhead expenses of the Fund's
Treasurer and the personnel operating under his direction. Charges are
allocated among all investment companies advised or sub-advised by the Adviser.
For the year ended September 30, 1994, these charges included $10,303 as the
Fund's share of the employee costs attributable to the Fund's accounting
officers. A portion of the accounting services expense was paid to the Adviser
in reimbursement of personnel, facilities and equipment costs attributable to
the provision of accounting services to the Fund. The services provided by the
Adviser are at cost.

American Capital Companies Shareholder Services, Inc., an affiliate of the
Adviser, serves as shareholder service agent.  These services are provided at
cost plus a profit. For the year ended September 30, 1994, the fees for such
services were $334,826.

The Fund has been advised that American Capital Marketing, Inc. (the
"Distributor") and Advantage Capital Corp. (the "Retailer Dealer"), both
affiliates of the Adviser, received $118,647 and $105,378, respectively, as
their portion of the commissions charged on sales of Fund shares during the
year.

Under the Distribution Plans, the Fund pays up to .25% per annum of its average
net assets to reimburse the Distributor for expenses and service fees incurred.
Class B shares and Class C shares pay an additional fee of up to .75% per annum
of their average daily net assets to reimburse the Distributor for its
distribution expenses. Actual distribution expenses incurred by the Distributor
for Class B shares and Class C shares may exceed the amounts reimbursed to the
Distributor by the Fund. At September 30, 1994, the unreimbursed expenses
incurred by the Distributor under the Class B and Class C plans aggregated
approximately $1.6 million and $130,000, respectively, and may be carried
forward and reimbursed through either the collection of the contingent deferred
sales charges from share redemptions or, subject to the annual renewal of the
plans, future Fund reimbursements of distribution fees.

Legal fees of $11,680 were for services rendered by O'Melveny & Myers, counsel
for the Fund. Lawrence J. Sheehan, of counsel to that firm, is a director of
the Fund.

Certain officers and directors of the Fund are officers and directors of the
Adviser, the Distributor, the Retail Dealer and the shareholder service agent.

Note 3-Investment Activity
During the year, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $45,734,980 and $21,355,006,
respectively.

For federal income tax purposes, the identified cost of investments owned at
September 30, 1994 was




                                     F-15
<PAGE>   99
$334,094,902. Net unrealized appreciation of investments aggregated
$15,335,537, gross unrealized appreciation of investments aggregated
$19,847,942, and gross unrealized depreciation of investments aggregated
$4,512,405.

The net realized capital loss carryforward for federal income tax purposes of
approximately $9.4 million at September 30, 1994 may be utilized to offset
current or future gains until expiration in 1996 through 2002.

Note 4-Director Compensation
Fund directors who are not affiliated with the Adviser are compensated by the
Fund at the annual rate of $1,320 plus a fee of $30 per day for Board and
Committee meetings attended. The Chairman receives additional fees from the
Fund at the annual rate of $490. During the year, such fees aggregated $13,494.

The directors may participate in a voluntary Deferred Compensation Plan (the
"Plan"). The Plan is not funded, and obligations under the Plan will be paid
solely out of the Fund's general accounts.  The Fund will not reserve or set
aside funds for the payment of its obligations under the Plan by any form of
trust or escrow. At September 30, 1994, the liability for the Plan aggregated
$25,830. The deferred fees have been credited with interest at a rate equal to
that earned by the Fund on its short-term investments.

Note 5-Capital
The Fund offers three classes of shares at their respective net asset values
per share, plus a sales charge which is imposed either at the time of purchase
(the Class A shares) or at the time of redemption on a contingent deferred
basis (the Class B shares and Class C shares). All classes of shares have the
same rights, except that Class B shares and Class C shares bear the cost of
distribution fees and certain other class specific expenses. Realized and
unrealized gains or losses, investment income and expenses (other than class
specific expenses) are allocated daily to each class of shares based upon the
relative proportion of net assets of each class. Class B shares and Class C
shares automatically convert to Class A shares six years and ten years after
purchase, respectively, subject to certain conditions.

The Fund has 200 million of each class of shares of $.01 par value of capital
stock authorized. Transactions in shares of capital stock were as follows:

(1)      Per share amounts for 1990 and 1991 are adjusted to reflect a 2 for 1
         stock split effected July 26, 1991.  Additionally, in 1991, the Fund
         adopted for financial reporting purposes a method of accounting for
         debt discounts and premiums which is the same as is used for federal
         income tax reporting. The effect of the change, on a pro forma basis,
         would have been to increase net investment income with a corresponding
         decrease in net realized and unrealized gains or losses in the amount
         of $.01 for 1990. Similarly, the ratio of net investment income to
         average net assets would have been 6.94%.
(2)      Per share amounts based on average month-end shares outstanding.  
(3)      Effective October 1, 1992, the Fund adopted Statement of Position 93-2,
         Determination, Disclosure and Financial Statement Presentation of 
         Income, Capital Gain and Return of Capital Distributions by Investment
         Companies.  Prior year financial information was not restated.

Report of Independent Accountants      

To the Shareholders and Board of Directors of
American Capital Municipal Bond Fund, Inc.

In our opinion, the accompanying statement of assets and liabilities, including
the investment portfolio, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of American Capital Municipal Bond
Fund, Inc. at September 30, 1994, and the results of its operations, the
changes in its net assets and the selected per share data and ratios for each
of the fiscal periods presented, in conformity with generally accepted
accounting principles. These financial statements and selected per share data
and ratios (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits, which included confirmation of securities at September 30, 1994 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

(1) Per share amounts for 1990 and 1991 are adjusted to reflect a 2 for 1 stock
    split effected July 26, 1991. Additionally, in 1991, the Fund adopted for
    financial reporting purposes a method of accounting for debt discounts and
    premiums which is the same as is used for federal income tax reporting. The
    effect of the change, on a pro forma basis, would have been to increase net
    investment income with a corresponding decrease in net realized and
    unrealized gains or losses in the amount of $.01 for 1990. Similarly, the
    ratio of net investment income to average net assets would have been 6.94%.
(2) Per share amounts based on average month-end shares outstanding.
(3) Total return for a period of less than one full year is not annualized.
    Total return does not consider the effect of sales charges.

(1) Sales of Class B commenced September 29, 1992 at a net asset value of
    $10.00 per share. At September 30, 1992, there were 50 Class B shares
    outstanding with a per share net asset value of $9.98. The decrease in net
    asset value was due principally to a dividend of $.052 per share. Other
    financial highlights for Class B shares for this short period (September
    29, 1992 to September 30, 1992) are not presented as they are not
    meaningful.

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES

American Capital Municipal Bond Fund (the "Fund") is registered under the In-
vestment Company Act of 1940, as amended, as a diversified open-end management
investment company. The following is a summary of significant accounting poli-
cies consistently followed by the Fund in the preparation of its financial
statements.
 
A. INVESTMENT VALUATIONS-Investments in municipal bonds are valued at the most
recently quoted bid prices or at bid prices based on a matrix system (which
considers such factors as security prices, yields, maturities and ratings)
furnished by dealers and an independent pricing service. Municipal variable
rate demand notes are valued at par; periodic rate changes reflect current
market conditions.

   Short-term investments with a maturity of 60 days or less when purchased are
valued at amortized cost, which approximates market value. Short-term invest-
ments with a maturity of more than 60 days when purchased are valued based on
market quotations until the remaining days to maturity becomes less than 61
days. From such time, until maturity, the investments are valued at amortized
cost.

   Issuers of certain securities owned by the Fund have obtained insurance
guaranteeing their timely payment of principal and interest at maturity. The
insurance reduces financial risk but not market risk of the security.

   Fund investments include lower rated debt securities which may be more sus-
ceptible to adverse economic conditions than other investment grade holdings.
These securities are often subordinated to the prior claims of other senior
lenders and uncertainties exist as to an issuer's ability to meet principal
and interest payments. At March 31, 1995, debt securities rated below invest-
ment grade and comparable unrated securities represented approximately 20% of
the investment portfolio.
 
B. FEDERAL INCOME TAXES-No provision for federal income taxes is required be-
cause the Fund has elected to be taxed as a "regulated investment company" un-
der the Internal Revenue Code and intends to maintain this qualification by
annually distributing all of its taxable net investment income and taxable net
realized capital gains to its shareholders. It is anticipated that no distri-
butions of net realized capital gains will be made until tax basis capital
loss carryforwards expire or are offset by net realized capital gains.

   The net realized capital loss carryforward for federal income tax purposes
of approximately $9.4 million at September 30, 1994 may be utilized to offset
current or future gains until expiration in 1996 through 2002.

- -------------------------------------------------------------------------------
C. INVESTMENT TRANSACTIONS AND RELATED INVESTMENT INCOME-Investment transac-
tions are accounted for on the trade date. Realized gains and losses on in-
vestments are determined on the basis of identified cost. Interest income is
accrued daily.
 
D. DIVIDENDS AND DISTRIBUTIONS-Dividends and distributions to shareholders are
recorded on the record date. The Fund distributes tax basis earnings in accor-
dance with the minimum distribution requirements of the Internal Revenue Code,
which may differ from generally accepted accounting principles. Such dividends
or distributions may exceed financial statement earnings.
 
E. DEBT DISCOUNT AND PREMIUM-The Fund accounts for debt discounts and premiums
on the same basis as is followed for federal income tax reporting. According-
ly, original issue discounts and all premiums are amortized over the life of
the security. Market discounts are recognized at the time of sale as realized
gains for book purposes and ordinary income for tax purposes.
 
F. EQUALIZATION-At September 30, 1994, the Fund discontinued the accounting
practice of equalization, which it had used since its inception. Equalization
is a practice whereby a portion of the proceeds from sales and costs of re-
demptions of Fund shares, equivalent on a per-share basis to the amount of the
undistributed net investment income, is charged or credited to undistributed
net investment income.
 
G. WHEN-ISSUED SECURITIES-Delivery and payment for securities purchased on a
when-issued basis may take place up to 45 days after the date of the transac-
tion. The securities purchased are subject to market fluctuation during this
period. To meet the payment obligation, sufficient cash or liquid securities
equal to the amount that will be due are set aside with the custodian.
 
NOTE 2--MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Van Kampen American Capital Asset Management, Inc. (the "Adviser") serves as
investment manager of the Fund. Management fees are paid monthly, based on the
rate of .50% per annum of the average daily net assets of the Fund.

   Accounting services include the salaries and overhead expenses of the Fund's
Treasurer and the personnel operating under his direction. Charges are allo-
cated among investment companies advised or sub-advised by the Adviser. For
the period March 31, 1995, these

- -------------------------------------------------------------------------------
charges included $5,384 as the Fund's share of the employee costs attributable
to the Fund's accounting officers. A portion of the accounting services ex-
pense was paid to the Adviser in reimbursement of personnel, facilities and
equipment costs attributable to the provision of accounting services to the
Fund. The services provided by the Adviser are at cost.

   ACCESS Investor Services, Inc., an affiliate of the Adviser, serves as
shareholder service agent. These services are provided at cost plus a profit.
For the period ended March 31, 1995, the fees for such services were $147,187.

   The Fund has been advised that Van Kampen American Capital Distributors,
Inc. (the "Distributor") and Advantage Capital Corp. (the "Retailer Dealer")
both affiliates of the Adviser, received $27,527 and $30,555, respectively, as
their portion of the commissions charged on sales of Fund shares during the
period.

   Under the Distribution Plans, the Fund pays up to .25% per annum of its av-
erage net assets to reimburse the Distributor for expenses and service fees
incurred. Class B shares and Class C shares pay an additional fee of up to
 .75% per annum of their average daily net assets to reimburse the Distributor
for its distribution expenses. Actual distribution expenses incurred by the
Distributor for Class B shares and Class C shares may exceed the amounts reim-
bursed to the Distributor by the Fund. At March 31, 1995, the unreimbursed ex-
penses incurred by the Distributor under the Class B and Class C plans
aggregated approximately $1.5 million and $110,000, respectively, and may be
carried forward and reimbursed through either the collection of the contingent
deferred sales charges from share redemptions or, subject to the annual re-
newal of the plans, future Fund reimbursements of distribution fees.

   Legal fees were for services rendered by O'Melveny & Myers, counsel for the
Fund. Lawrence J. Sheehan, of counsel to that firm, is a director of the Fund.

   Certain officers and directors of the Fund are officers and directors of the
Adviser, the Distributor, the Retail Dealer and the shareholder services
agent.
 
NOTE 3--INVESTMENT ACTIVITY

During the period, the cost of purchases and proceeds from sales of invest-
ments, excluding short-term investments, were $8,215,930 and $12,451,313, re-
spectively.

   For federal income tax purposes, the identified cost of investments owned at
March 31, 1995 was $326,964,141. Net unrealized appreciation of investments
aggregated $20,766,187, gross unrealized appreciation of investments aggre-
gated $23,399,469, and gross unrealized depreciation of investments aggregated
$2,633,282.

NOTE 4--DIRECTOR COMPENSATION

Fund directors who are not affiliated with the Adviser are compensated by the
Fund at the annual rate of $1,250 plus a fee of $30 per day for Board and Com-
mittee meetings attended. The Chairman receives additional fees from the Fund
at the annual rate of $470. During the period, such fees aggregated $7,453.

   The directors may participate in a voluntary Deferred Compensation Plan (the
"Plan"). The Plan is not funded, and obligations under the Plan will be paid
solely out of the Fund's general accounts. The Fund will not reserve or set
aside funds for the payment of its obligations under the Plan by any form of
trust or escrow. Each director covered by the Plan elects to be credited with
an earnings component on amounts deferred equal to the income earned by the
Fund on its short-term investments or equal to the total return of the Fund.
 
NOTE 5--CAPITAL

The Fund offers three classes of shares at their respective net asset values
per share, plus a sales charge which is imposed either at the time of purchase
(the Class A shares) or at the time of redemption on a contingent deferred ba-
sis (the Class B shares and Class C shares). All classes of shares have the
same rights, except that Class B shares and Class C shares bear the cost of
distribution fees and certain other class specific expenses. Realized and
unrealized gains or losses, investment income and expenses (other than class
specific expenses) are allocated daily to each class of shares based upon the
relative proportion of net assets of each class. Class B shares and Class C
shares automatically convert to Class A shares six years and ten years after
purchase, respectively, subject to certain conditions.
