DEAR VAN KAMPEN AMERICAN CAPITAL MUNICIPAL BOND FUND SHAREHOLDER:
 
  Enclosed is information asking you for your vote on a reorganization (the
"Reorganization") pursuant to an Agreement and Plan of Reorganization (the
"Agreement") for the Van Kampen American Capital Municipal Bond Fund (the "AC
Fund"). The Reorganization calls for the AC Fund shareholders to become
shareholders of the Van Kampen American Capital Municipal Income Fund (the "VK
Fund"), a mutual fund which pursues a substantially similar investment
objective.
 
  The enclosed materials include a combined Proxy Statement/Prospectus
containing information you need to make an informed decision. However, we
thought it would also be helpful for you to have, at the start, answers to some
of the important questions you might have about the proposed Reorganization. We
hope you find these explanations useful as you review your materials before
voting. For more detailed information about the Reorganization, please refer to
the combined Proxy Statement/Prospectus.
 
HOW WILL THE REORGANIZATION AFFECT ME?
 
  Assuming shareholders of the AC Fund approve the Reorganization, the assets
and liabilities of the AC Fund will be combined with those of the VK Fund and
you will become a shareholder of the VK Fund. You will receive shares of the VK
Fund approximately equal in value at the time of issuance to the shares of the
AC Fund that you hold immediately prior to the Reorganization. See the section
of the combined Proxy Statement/Prospectus entitled "Distributor, Purchase,
Valuation, Redemption and Exchange of Shares." Class A shareholders of the AC
Fund will receive Class A shares of the VK Fund; Class B shareholders of the AC
Fund will receive Class B shares of the VK Fund; and Class C shareholders of the
AC Fund will receive Class C shares of the VK Fund.
 
WHY IS THE REORGANIZATION BEING RECOMMENDED?
 
  As we reported to you earlier, the parent company of Van Kampen American
Capital Asset Management, Inc. ("AC Adviser"), the investment adviser to the AC
Fund, was acquired in December 1994 by Van Kampen American Capital, Inc.
("VKAC"), and was subsequently merged into VKAC. VKAC, through its wholly owned
subsidiaries, distributes and manages the Van Kampen American Capital funds. AC
Adviser is an affiliate of Van Kampen American Capital Investment Advisory Corp.
("VK Adviser"), the investment adviser to the VK Fund. The primary purposes of
the proposed Reorganization are to seek to achieve future economies of scale and
eliminate certain costs associated with operating the AC Fund and the VK Fund
separately. The Reorganization will result in combining the assets and
liabilities of the AC Fund with the assets and liabilities of the VK Fund and
consolidating their operations.
<PAGE>   2
 
  The Reorganization is intended to provide various benefits to shareholders of
the AC Fund who become shareholders of the VK Fund (as well as to existing and
future investors in the VK Fund). For example, higher net asset levels would
enable the VK Fund to spread fixed and relatively fixed costs, such as
accounting, legal and printing expenses, over a larger asset base, thereby
potentially reducing per share expense levels. Higher net asset levels also may
benefit portfolio management by permitting larger individual portfolio
investments that may result in reduced transaction costs or more favorable
pricing and by providing the opportunity for greater portfolio diversity. These
benefits, in turn, should have a favorable effect on the relative performance of
the VK Fund.
 
  The consummation of the Reorganization is subject to the satisfaction of a
number of conditions (including approval by the AC Fund's shareholders), which
are summarized below in "The Proposed Reorganization -- Terms of the Agreement"
section of the accompanying combined Proxy Statement/Prospectus. These
conditions are stated in the Agreement which is attached as Exhibit A to the
combined Proxy Statement/Prospectus.
 
WILL I HAVE TO PAY ANY SALES LOAD, COMMISSION OR OTHER TRANSACTIONAL FEE IN
CONNECTION WITH THE REORGANIZATION?
 
  No. The full value of your shares of the AC Fund will be exchanged for shares
of the corresponding class of the VK Fund without any sales load, commission or
other transactional fee being imposed. As more fully discussed in the combined
Proxy Statement/Prospectus, the holding period for shareholders acquiring Class
B or Class C shares of the VK Fund in the Reorganization subject to a contingent
deferred sales charge will be measured from the time (i) the holder purchased
Class B or C shares from the AC Fund or (ii) purchased Class B or C shares of
any other Van Kampen American Capital open-end fund and subsequently exchanged
into Class B or C shares of the AC Fund. If the Reorganization is completed, the
VK Fund will bear the costs associated with the Reorganization, such as printing
and mailing costs and other expenses associated with the Special Meeting. If the
Reorganization is not completed VKAC will bear the costs associated with the
Reorganization.
 
HOW WILL THE FEES PAID BY THE VK FUND COMPARE TO THOSE PAYABLE BY THE AC FUND?
 
  It is anticipated that, on a per share basis, the total of the various fees
and expenses incurred by the VK Fund will be less, upon completion of the
Reorganization, than the total of such fees and expenses applicable to the AC
Fund.
<PAGE>   3
 
WHAT WILL I HAVE TO DO TO OPEN AN ACCOUNT IN THE VK FUND? WHAT HAPPENS TO MY
ACCOUNT IF THE REORGANIZATION IS APPROVED?
 
  If the Reorganization is approved, your interest in Class A, B or C shares of
the AC Fund will automatically be converted into the same class of shares of the
VK Fund and we will send you written confirmation that this change has taken
place. You will receive the same class of shares of the VK Fund approximately
equal in value to your Class A, B or C shares of the AC Fund. No certificates
for VK Fund shares will be issued in connection with the Reorganization,
although such certificates will be available upon request. If you currently hold
certificates representing your shares of the AC Fund, it is not necessary to
surrender such certificates.
 
WHO WILL ADVISE THE VK FUND AND PROVIDE OTHER SERVICES?
 
  The VK Adviser provides advisory services to the VK Fund under an arrangement
that is substantially similar to that currently in effect between the AC Fund
and AC Adviser. The contractual advisory fees payable by the VK Fund are no
higher than the contractual advisory fees applicable to the AC Fund. Van Kampen
American Capital Distributors, Inc. serves as distributor of shares of both the
VK Fund and the AC Fund. In addition, State Street Bank & Trust Company, 225
Franklin Street, P.O. Box 1713, Boston, Massachusetts 02105-1713, is the
custodian of both the VK Fund and the AC Fund. ACCESS Investor Services, Inc.
("ACCESS"), P.O. Box 418256, Kansas City, Missouri 64141-9256, serves as the
transfer agent for both the VK Fund and the AC Fund.
 
WILL I HAVE TO PAY ANY FEDERAL TAXES AS A RESULT OF THE REORGANIZATION?
 
  The Reorganization is intended to qualify as a "reorganization" within the
meaning of Section 368(a)(1) of the Internal Revenue Code of 1986, as amended
(the "Code"). If the Reorganization so qualifies, in general, a shareholder of
the AC Fund will recognize no gain or loss upon the receipt of solely the shares
of the VK Fund in connection with the Reorganization. Additionally, the AC Fund
would not recognize any gain or loss as a result of the transfer of all of its
assets and liabilities solely in exchange for the shares of the VK Fund or as a
result of its liquidation. The VK Fund expects that it will not recognize any
gain or loss as a result of the Reorganization, that it will take a carryover
basis in the assets acquired from the AC Fund and that its holding period of
such assets will include the period during which assets were held by the AC
Fund. See "The Proposed Reorganization -- Federal Income Tax Consequences" in
the combined Proxy Statement/ Prospectus.
 
WHAT IF I REDEEM MY AC FUND SHARES BEFORE THE REORGANIZATION TAKES PLACE?
 
  If you choose to redeem your shares of AC Fund before the Reorganization takes
place, the redemption will be treated as a normal redemption of shares and will
be a
<PAGE>   4
 
taxable transaction, unless your account is not subject to taxation, such as an
individual retirement account or other tax-qualified retirement plan.
 
  We hope these answers help to clarify the Reorganization proposal for you. If
you still have questions, do not hesitate to call us at 1-800-341-2911. Please
give this matter your prompt attention. We need to receive your proxy before the
shareholder meeting scheduled for September 15, 1995. If shareholders approve
the Reorganization, it is expected to take effect on September 22, 1995.
 
  Thank you for your investment in Van Kampen American Capital Municipal Bond
Fund.
 
                                          Very truly yours,

                               SEPTEMBER 15, 1995
 
  A Special Meeting of Shareholders of Van Kampen American Capital Municipal
Bond Fund (the "AC Fund") will be held at the Hyatt Regency Oak Brook, 1909
Spring Road, Oak Brook, Illinois 60521, on September 15, 1995 at 2:00 p.m. (the
"Special Meeting"), for the following purposes:
 
    (1) To approve a plan of reorganization pursuant to which the AC Fund would
  transfer all of its assets and liabilities to the Van Kampen American Capital
  Municipal Income Fund (the "VK Fund") in exchange for corresponding Class A, B
  and C shares of beneficial interest of the VK Fund, the AC Fund would
  distribute such Class A, B and C shares of the VK Fund to the holders of Class
  A, B and C shares of the AC Fund, respectively, and the AC Fund would be
  dissolved.
 
    (2) To transact such other business as may properly come before the Special
  Meeting.
 
  The Special Meeting is scheduled to be held jointly with the special meetings
of the respective shareholders of five other Van Kampen American Capital Funds
because the shareholders of each of such funds are expected to consider and vote
on similar matters. In the event that any shareholder of any Van Kampen American
Capital Fund present at the special meetings objects to the holding of a joint
meeting and moves for an adjournment of the meeting of such fund to a time
immediately after the other special meetings so that such fund's special meeting
may be held separately, the persons named as proxies will vote in favor of such
adjournment. Shareholders of each Van Kampen American Capital Fund will vote
separately on each of the proposals relating to their fund, and an unfavorable
vote on a proposal by the shareholders of one fund will not affect the
implementation of such a proposal by another fund if the proposal is approved by
the shareholders of that fund.
 
  Shareholders of record as of the close of business on August 1, 1995 are
entitled to vote at the Special Meeting or any adjournment thereof.
 
                                       For the Board of Trustees,

                VAN KAMPEN AMERICAN CAPITAL MUNICIPAL BOND FUND
 
                           PROXY STATEMENT/PROSPECTUS
            RELATING TO THE ACQUISITION OF ASSETS AND LIABILITIES OF
                VAN KAMPEN AMERICAN CAPITAL MUNICIPAL BOND FUND
                        BY AND IN EXCHANGE FOR SHARES OF
               VAN KAMPEN AMERICAN CAPITAL MUNICIPAL INCOME FUND
 
  This Proxy Statement/Prospectus is being furnished to shareholders of the Van
Kampen American Capital Municipal Bond Fund (the "AC Fund"), and relates to the
Special Meeting of Shareholders of the AC Fund (the "Special Meeting") called
for the purpose of approving the proposed reorganization of the AC Fund (the
"Reorganization") which would result in shareholders of the AC Fund in effect
exchanging their Class A, B and C shares of the AC Fund for Class A, B and C
shares, respectively, of the Van Kampen American Capital Municipal Income Fund
(the "VK Fund"), a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust (the "VKAC Tax Free Trust"). The Reorganization would be
accomplished as follows: (1) the VK Fund would acquire all the then existing
assets and liabilities of the AC Fund in exchange for Class A, B and C shares of
beneficial interest of the VK Fund (the "Shares"); (2) the AC Fund would
distribute the Shares to the AC Fund shareholders holding the same respective
class of shares; and (3) the AC Fund would dissolve and all shares of the AC
Fund would be cancelled.
 
  The VK Fund, an open-end, diversified management investment company, is one of
twelve series of the VKAC Tax Free Trust, which is authorized to issue an
unlimited number of shares of beneficial interest, par value $.01 per share, for
each series authorized by its Board of Trustees. Each series represents
interests in a separate portfolio of securities and other assets, with its own
investment objectives and policies. The investment objective of the VK Fund is
to provide investors with a high level of current income exempt from federal
income tax consistent with preservation of capital, which is substantially
similar to that of the AC Fund. (See "Comparisons of the VK Fund and AC
Fund -- Investment Objectives and Policies" below.) There can be no assurance
that the VK Fund will achieve its investment objective. The address, principal
executive office and telephone number of the VKAC Tax Free Trust is One Parkview
Plaza, Oakbrook Terrace, Illinois 60181, (708) 684-6000 or (800) 225-2222. The
address, principal executive office and telephone number of the AC Fund is 2800
Post Oak Boulevard, Houston, Texas 77056, (800) 421-5666. The enclosed proxy and
this Proxy Statement/Prospectus are first being sent to AC Fund shareholders on
or about August 2, 1995.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE
   SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
       PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROXY STATEMENT/
           PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A

             APPROVAL OR DISAPPROVAL OF THE PROPOSED REORGANIZATION
 
A. SUMMARY
 
  The following is a summary of, and is qualified by references to, the more
complete information contained in this Proxy Statement/Prospectus, including the
Agreement and Plan of Reorganization by and between the AC Fund and the VKAC Tax
Free Fund attached hereto as Exhibit A (the "Agreement"), the prospectus of the
AC Fund dated August 1, 1995 (the "AC Fund Prospectus") incorporated herein by
reference and the prospectus of the VK Fund dated July 31, 1995 (the "VK Fund
Prospectus") incorporated herein by reference and accompanying this Proxy
Statement/Prospectus. This Proxy Statement/Prospectus constitutes an offering of
Class A, B and C Shares of the VK Fund only.
 
THE REORGANIZATION
 
  On May 11, 1995, the Board of Trustees of the AC Fund (the "AC Board")approved
the Agreement. The Agreement provides that the AC Fund will transfer all of its
assets and liabilities to the VK Fund in exchange for Class A, B and C shares of
the VK Fund. At the Closing (as defined herein), the VK Fund will issue Shares
of the VK Fund to the AC Fund which VK Fund Shares will have an aggregate net
asset value approximately equal in amount to the net asset value of the AC Fund
net assets as of the Closing. See "Distribution, Purchase, Valuation and
Redemption of Shares" below. The Agreement provides that the AC Fund will
dissolve pursuant to a plan of liquidation and dissolution to be adopted by the
AC Board following the Closing, and as part of such dissolution, will distribute
to each shareholder of the AC Fund Shares of the respective class of the VK Fund
approximately equal in value to their existing shares in the AC Fund. All
members of the AC Board were elected as trustees of the VK Fund on July 21,
1995.
 
  The AC Board has unanimously determined that the Reorganization is in the best
interests of shareholders of each class of shares of the AC Fund and that the
interests of such shareholders will not be diluted as a result of the
Reorganization. Similarly, the Board of Trustees of the VKAC Tax Free Fund (the
"VK Board") has unanimously determined that the Reorganization is in the best
interests of the VK Fund and that the interests of each class of shares of
existing shareholders of the VK Fund will not be diluted as a result of the
Reorganization. Management of the respective funds believes that the proposed
Reorganization of the AC Fund into the VK Fund should allow the VK Fund to
achieve future economies of scale and eliminate certain costs of operating the
AC Fund and the VK Fund separately.
 
  The VK Fund has agreed to pay all of the costs of soliciting approval of the
Reorganization by the AC Fund's shareholders and related costs of the
Reorganization in the event the Reorganization is completed, including expenses
incurred by the AC
 
                                        4

Fund. Accordingly, if the Reorganization is completed, shareholders of the VK
Fund after the Reorganization will bear a pro rata portion of such expenses. If
the Reorganization is not completed VKAC will bear the costs associated with the
Reorganization.
 
  The AC Board is asking shareholders of the AC Fund to approve the
Reorganization at a Special Meeting to be held on September 15, 1995. If
shareholders of the AC Fund approve the Reorganization, it is expected that the
Closing will be on September 22, 1995, but it may be at a different time as
described herein.
 
  THE AC BOARD RECOMMENDS THAT YOU VOTE FOR THE REORGANIZATION. APPROVAL OF THE
REORGANIZATION REQUIRES THE FAVORABLE VOTE OF THE HOLDERS OF A MAJORITY OF THE
OUTSTANDING SHARES ENTITLED TO VOTE. SEE "VOTING INFORMATION AND REQUIREMENTS."
 
COMPARISONS OF THE VK FUND AND THE AC FUND
 
  The principal changes which would result from the Reorganization are listed
below:
 
  (1) The holders of Class A, B and C shares of the AC Fund would become holders
      of the same class of Shares, respectively, of the VK Fund. The AC Fund and
      the VK Fund have substantially similar investment objectives and follow
      similar investment strategies. Like the AC Fund, the VK Fund also has the
      ability to utilize options and futures, but it may also engage in interest
      rate transactions such as swaps, caps, floors or collars. In addition, the
      VK 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 AC Fund may only invest up to 20% of its assets in
      such securities.
 
  (2) The VK Fund is managed by Van Kampen American Capital Investment Advisory
      Corp. ("VK Adviser"), an affiliate of the AC Fund's investment adviser,
      Van Kampen American Capital Asset Management, Inc. ("AC Adviser"). The
      annual advisory fee for the VK Fund is 0.50% of its average net assets up
      to $500 million and 0.45% on net assets over $500 million. As of March 31,
      1995, the VK Fund's net assets were approximately $691.9 million. The
      annual advisory fee for the AC Fund is 0.50% of its daily net assets. As
      of March 31, 1995, the AC Fund's net assets were approximately $352.2
      million.
 
  (3) Both the AC Fund and the VK Fund offer three classes of shares. The Class
      A shares of both the VK Fund and the AC Fund are subject to an initial
      sales charge of up to 4.75%. However, the initial sales charge applicable
      to Class A shares of the VK Fund will be waived for Class A Shares
      acquired in the Reorganization. Any subsequent purchases of Class A shares
      of the VK Fund after the Reorganization will be subject to an initial
      sales charge of up to 4.75%, excluding Class A Shares purchased
 
                                        5
<PAGE>   11
 
      through the dividend reinvestment plan. Purchases of Class A shares of the
      VK Fund or the AC Fund in amounts of $1,000,000 or more are not subject to
      an initial sales charge but a contingent deferred sales charge of 1.00%
      may be imposed on certain redemptions made within the first year after
      purchase. Class B Shares of the VK Fund and Class B shares of the AC Fund
      do not incur a sales charge when they are purchased, but generally are
      subject to a contingent deferred sales charge of 4.00% if redeemed within
      the first year after purchase, which charge is reduced to zero over a six
      year period in the case of the VK Fund and over a five year period in the
      case of the AC Fund. However, Class B Shares of the VK Fund acquired in
      the Reorganization will remain subject to the contingent deferred sales
      charge applicable to Class B shares of the AC Fund. Class C shares of the
      VK Fund and the AC Fund do not incur a sales charge when purchased, but
      are subject to a contingent deferred sales charge of 1.00% if redeemed
      within the first year after purchase.
 
  (4) Both the AC Fund and the VK Fund have adopted distribution plans (the
      "Distribution Plans") pursuant to Rule 12b-1 under the Act and have
      adopted service agreements or plans (the "Service Plans"). Both the VK
      Fund and the AC Fund can pay up to 0.75% of their respective average daily
      net assets attributable to Class B and C shares for reimbursement of
      certain distribution-related expenses. In addition, both the VK Fund and
      the AC Fund can pay up to 0.25% of the respective average daily net assets
      attributable to Class A, B and C shares for the provision of ongoing
      services to shareholders. Class B shares of the VK Fund and the AC Fund
      automatically convert to Class A shares after six years. Unlike Class C
      shares of the VK Fund, Class C shares of the AC Fund automatically convert
      to Class A shares after ten years. However, Class B and C Shares of the VK
      Fund acquired in the Reorganization will automatically convert to Class A
      shares of the VK Fund in accordance with the same conversion schedule
      applicable to Class B and C shares of the AC Fund, respectively.
 
  Certain other comparisons between the AC Fund and the VK Fund are discussed
below.
 
  INVESTMENT OBJECTIVES AND POLICIES
 
  The VK Fund and the AC Fund have substantially similar investment objectives
and also share similar investment practices, but there are also certain
differences in their investment policies, practices and restrictions. The
investment objective of the VK Fund is to provide a high level of current income
exempt from federal income tax, consistent with preservation of capital. The
investment objective of the AC Fund is to provide as high a level of current
interest income exempt from federal income tax as is consistent with the
preservation of capital.
 
  The VK Fund and the AC Fund attempt to achieve their investment objectives by
generally investing at least 80% of their assets in diversified portfolios of
tax exempt municipal securities rated investment grade at the time of
investment. Additionally, the AC Fund may not invest more than 50% of its assets
in securities
 
                                        6
<PAGE>   12
 
rated in a category below the top three ratings categories of Standard & Poor's
Corporation ("S&P") and Moody's Investors Service, Inc. ("Moody's"). The VK Fund
has no such restriction. The VK Fund has the flexibility to invest in municipal
bonds rated, at the time of investment, between BB and B- (inclusive) by S&P or
between Ba and B3 (inclusive) by Moody's, while the AC Fund may not invest in
municipal bonds rated, at the time of investment, below B by S&P and Moody's.
 
  As the table below indicates, the holdings of the VK Fund and the AC Fund have
similar credit quality, although a larger percentage of the VK Fund's holdings
have the highest credit rating of Moody's and Standard & Poor's. Unlike the AC
Fund, the VK Fund's policy as to ratings is not fundamental and may be changed
without shareholder approval.
 
  In addition, the VK Fund may invest a substantial portion of its assets in
securities which are subject to the alternative minimum tax, while the AC Fund
may only invest up to 20% of its assets in such securities. Like the AC Fund,
the VK Fund has the ability to utilize options and futures, but it may also
engage in interest rate transactions such as swaps, caps, floors or collars.
 
  A comparison of the credit quality of the respective portfolios of the VK Fund
and the AC Fund, as of March 31, 1995, is set forth in the table below.

value at the annual rate of 0.50% of the AC Fund's average net assets. In
addition, the AC Fund bears most expenses associated with its operation and the
issuance and repurchase or redemption of its securities, except for the

Service Plan with respect to each class of its shares. The Distribution Plan and
the Service Plan provide that the VK Fund can pay up to 0.25%, 1.00% and 1.00%
of the VK Fund's average daily net assets attributable to the Class A, B and C

the AC Fund, see the respective sections in the AC Fund's Prospectus and
Statement of Additional Information entitled "Distribution Plans."
 
  DISTRIBUTION, PURCHASE, VALUATION, REDEMPTION AND EXCHANGE OF SHARES
 
  Generally, Class A Shares of the VK Fund and the AC Fund are sold at net asset
value applicable at the time of such sale, plus a sales charge of up to 4.75% of
the offering price (which percentage is reduced on investments of $100,000 or
more), and are redeemable at their net asset value applicable at the time of
redemption. Purchases of Class A shares of the VK Fund and the AC Fund in
amounts of $1,000,000 or more are not subject to an initial sales charge, but a
contingent deferred sales charge of 1.00% may be imposed on certain redemptions
made within one year of purchase. Class A Shares of the VK Fund acquired in the
Reorganization will not be subject to a sales charge.
 
  Generally, Class B shares of the VK Fund and the AC Fund do not incur a sales
charge when they are purchased, but generally are subject to a contingent
deferred sales charge if redeemed within a specified period of time from the
date of purchase. Class B Shares of the VK Fund are subject to a contingent
deferred sales charge equal to 4.00% of the lesser of the then current net asset
value or the original purchase price on Class B Shares redeemed during the first
year after purchase, which charge is reduced to zero over a six year period.
Class B shares of the AC Fund are subject to a contingent deferred sales charge
equal to 4.00% of the lesser of the then current net asset value or the original
purchase price on Class B shares redeemed during the first year after purchase,
which charge is reduced to zero over a five year period. However, Class B Shares
of the VK Fund acquired in the Reorganization will remain subject to the
contingent deferred sales charge applica-
 
                                        9
<PAGE>   15
 
ble to Class B shares of the AC Fund. Class B shares of the AC Fund and the VK
Fund automatically convert to Class A shares six years after purchase.
 
  Generally, Class C shares of the VK Fund and the AC Fund do not incur a sales
charge if redeemed after the first year after purchase. Both Class C shares of
the VK Fund and the AC Fund are subject to a contingent deferred sales charge
equal to 1.00% of the lesser of the then current net asset value or the original
purchase price on such shares redeemed during the first year after purchase and
do not incur a sales charge if redeemed after the first year from the date of
purchase. See "Fee Comparisons" below. Class C shares of the AC Fund
automatically convert to Class A shares after ten years. Class C shares of the
VK Fund have no such automatic conversion feature. However, Class C Shares of
the VK Fund acquired in the Reorganization will remain subject to the conversion
schedule applicable to Class B shares of the AC Fund.
 
  With respect to fixed income securities, the VK Fund and the AC Fund use
different pricing methodologies in calculating net asset value per share, each
of which is widely used and generally accepted in the mutual fund industry. In
determining net asset value per share, the VK Fund generally values fixed income
portfolio securities once daily by using prices equal to the mean of the last
reported bid and ask price of such securities as of 5:00 p.m. eastern time. When
calculating the net assets of the AC Fund in accordance with this pricing
methodology, the net asset value per share would have been $10.12, $10.12 and
$10.13 on July 21, 1995 for Classes A, B and C, respectively. The AC Fund,
however, generally computes net asset value per share by valuing fixed income
securities using the last reported bid price. When calculating the net assets of
the AC Fund in accordance with this pricing methodology, the net asset value per
share was $10.08, $10.08 and $10.09 on July 21, 1995 for Classes A, B and C,
respectively. In connection with the Reorganization, the net assets of the AC
Fund will be calculated using the current pricing methodology of the VK Fund.
For this reason the value of the VK Fund Shares received in connection with the
Reorganization may be approximately equal in value to the shares of the AC Fund
held immediately prior to the Reorganization rather than identical in value.
 
  The minimum initial investment with respect to each class of shares in the VK
Fund and the AC Fund is $500, although Shares of the VK Fund acquired in
connection with the Reorganization will not be subject to the minimum investment
limitation. The minimum subsequent investment in the VK Fund and the AC Fund is
$25. For a complete description of these arrangements with respect to the VK
Fund, see the section in the VK Fund Prospectus entitled "Purchase of Shares."
For a complete description of these arrangements with respect to the AC Fund,
see the respective sections in the AC Fund's Prospectus and Statement of
Additional Information entitled "Purchase of Shares" and "Purchase and
Redemption of Shares."
 
  Shares of either the AC Fund or the VK Fund may be purchased by check, by
electronic transfer or by bank wire and also offer exchange privileges among all
 
                                       10
<PAGE>   16
 
other Van Kampen American Capital open-end mutual funds distributed by VKAC
Distributors (except Van Kampen American Capital Government Target Fund).
 
  Shares of the VK Fund and the AC Fund properly presented for redemption may be
redeemed or exchanged at the next determined net asset value per share (subject
to any applicable deferred sales charge). Shares of either the AC Fund or the VK
Fund may be redeemed or exchanged by mail or by special redemption privileges
(telephone exchange, telephone redemption, by check or electronic transfer). If
a shareholder of either fund attempts to redeem shares within a short time after
they have been purchased by check, the respective fund may delay payment of the
redemption proceeds until such fund can verify that payment for the purchase of
the shares has been (or will be) received. No further purchases of the shares of
the AC Fund may be made after the date on which the shareholders of the AC Fund
approve the Reorganization, and the stock transfer books of the AC Fund will be
permanently closed as of the date of Closing. Only redemption requests and
transfer instructions received in proper form by the close of business on the
day prior to the date of Closing will be fulfilled by the AC Fund. Redemption
requests or transfer instructions received by the AC Fund after that date will
be treated by the AC Fund as requests for the redemption or instructions for
transfer of the shares of the VK Fund credited to the accounts of the
shareholders of the AC Fund. Redemption requests or transfer instructions
received by the AC Fund after the close of business on the day prior to the date
of Closing will be forwarded to the VK Fund. For a complete description of the
redemption arrangements for the VK Fund, see the section in the VK Fund's
Prospectus entitled "Redemption of Shares," and the sections in the AC Fund's
Prospectus and Statement of Additional Information entitled "Redemption of
Shares" and "Purchase and Redemption of Shares."
 
  The differences in the distribution, purchase and redemption procedures and
fee structure of the shares of the VK Fund and the shares of the AC Fund are
highlighted in the table below.

FEDERAL INCOME TAX CONSEQUENCES
 
  The Reorganization is intended to qualify as a "reorganization" within the
meaning of Section 368(a)(1) of the Internal Revenue Code of 1986, as amended
(the "Code"). If the Reorganization so qualifies, in general a shareholder of
the AC Fund will recognize no gain or loss upon the receipt of solely the shares
of the VK
 
                                       14
<PAGE>   20
 
Fund pursuant to the Reorganization. Additionally, the AC Fund would not
recognize any gain or loss as a result of the exchange of all of its assets for
the shares of the VK Fund or as a result of its liquidation. The VK Fund expects
that it will not recognize any gain or loss as a result of the Reorganization,
that it will take a carryover basis in the assets acquired from the AC Fund and
that its holding period of such assets will include the period during which the
assets were held by the AC Fund. See "The Proposed Reorganization -- Federal
Income Tax Consequences."
 
  The above information is only a summary of more complete information contained
in this Proxy Statement/Prospectus and the related Statement of Additional
Information.
 
REASONS FOR THE PROPOSED REORGANIZATION
 
  On December 20, 1994, The Van Kampen Merritt Companies, Inc. acquired from The
Travelers Inc. all of the outstanding capital stock of American Capital
Management & Research, Inc., the parent company of the AC Adviser. Immediately
after the acquisition, American Capital Management & Research, Inc. was merged
into The Van Kampen Merritt Companies, Inc. and the combined entity was renamed
Van Kampen American Capital, Inc. ("VKAC"). The VK Adviser and the AC Adviser
currently are each wholly-owned subsidiaries of VKAC.
 
  On February 10, 1995, the VK Board and AC Board held a joint meeting to
discuss with management ("Management") of the VK Adviser and the AC Adviser the
costs and potential benefits to shareholders of, among other things, (i)
combining certain funds advised by the VK Adviser and the AC Adviser, including
the VK Fund and the AC Fund, in order to seek to achieve certain economies of
scale and efficiencies, (ii) permitting exchangeability of shares between funds
advised by the VK Adviser and the AC Adviser, (iii) selecting a common transfer
agent to facilitate exchangeability and enhance shareholder services, and (iv)
consolidating the VK Board and the AC Board into a combined board of trustees
(collectively, the "Consolidation").
 
  The VK Board and the AC Board created a joint committee (the "Joint
Committee") to consider the possible costs and benefits to shareholders
associated with the proposed Consolidation, including the combination of the VK
Fund and the AC Fund. The Joint Committee held meetings on February 20, 1995,
March 27, 1995 and April 3, 1995 to consider issues relating to the
Consolidation, review information requested from and provided by Management and
review information requested from and provided by third-party analytical
services.
 
  The VK Board and the AC Board held joint meetings on March 14, 1995 and April
6-7, 1995 to review the findings and recommendations of the Joint Committee. The
VK Board unanimously approved each element of the Consolidation,
 
                                       15
<PAGE>   21
 
including the combination of the VK Fund and AC Fund, on April 7, 1995 subject
to approval of the Consolidation by the AC Board. The AC Board met May 11, 1995,
and unanimously approved each element of the Consolidation, including the
combination of the VK Fund and the AC Fund. Each of the VK Board and the AC
Board also approved submitting the necessary proposals to the respective
shareholders of the VK Fund and the AC Fund to effect the Consolidation.
 
  At separate shareholder meetings held on July 21, 1995, the shareholders of
the VK Fund and the AC Fund approved the reorganization of the VK Fund and the
AC Fund into Delaware business trusts (or series thereof) and the combination of
the VK Board and the AC Board. Shareholders of the AC Fund are now being asked
to approve its combination with the VK Fund in order to (i) eliminate the
duplication of services that currently exists as a result of the separate
operations of the funds, (ii) seek to achieve economies of scale by combining
the assets of the funds and (iii) potentially reduce transaction costs and
obtain greater portfolio diversity.
 
  In connection with approving the combination of the AC Fund with the VK Fund,
the AC Board considered the costs resulting from the separate operations of the
AC Fund and the VK Fund in light of their substantially similar investment
objectives, policies and restrictions. The AC Board also considered the
potential expense savings, economies of scale, reduced per-share expenses and
benefits to the portfolio management process that could result from combining
the assets and operations of the AC Fund and the VK Fund. In this regard, the AC
Board reviewed information provided by the AC Adviser, VK Adviser and VKAC
Distributors, relating to the anticipated cost savings to the shareholders of
the AC Fund and the VK Fund as a result of the Reorganization.
 
  In particular, the AC Board considered the probability that the elimination of
duplicative operations and the increase in asset levels of the VK Fund after the
Reorganization would result in the following potential benefits for investors,
although there can, of course, be no assurances in this regard:
 
  (1) ELIMINATION OF SEPARATE OPERATIONS.  Consolidating the AC Fund and the VK
      Fund should eliminate the duplication of services that currently exists as
      a result of their separate operations. For example, currently the AC Fund
      and the VK Fund are managed separately by different affiliated investment
      entities. Consolidating the separate operations of the AC Fund with those
      of the VK Fund should promote more efficient operations on a more cost-
      effective basis.
 
  (2) ACHIEVEMENT OF REDUCED PER-SHARE EXPENSES AND ECONOMIES OF SCALE.
      Combining the net assets of the AC Fund with the assets of the VK Fund
      also should lead to reduced expenses, on a per share basis, by allowing
      fixed and relatively fixed costs, such as accounting, legal and printing
      expenses, to
 
                                       16
<PAGE>   22
 
      be spread over a larger asset base. An increase in the asset levels of the
      VK Fund also could result in achieving future economies of scale, which
      should also reduce per share expenses. Any significant reductions in
      expenses on a per share basis should, in turn, have a favorable effect on
      the relative total return of the VK Fund.
 
  (3) BENEFITS TO THE PORTFOLIO MANAGEMENT PROCESS.  Higher net asset levels
      also should enable the VK Fund to purchase larger individual portfolio
      investments that may result in reduced transaction costs or other more
      favorable pricing and provide the opportunity for greater portfolio
      diversity.
 
  In determining whether to recommend approval of the Reorganization to
shareholders of the AC Fund, the AC Board considered a number of factors,
including, but not limited to: (1) capabilities and resources of VK Adviser and
other service providers to the VK Fund in the areas of marketing, investment and
shareholder services; (2) expenses and advisory fees applicable to the AC Fund
and the VK Fund before the Reorganization and the estimated expense ratios of
the VK Fund after the Reorganization; (3) the comparative investment performance
of the AC Fund and the VK Fund, as well as the performance of the VK Fund
compared to its peers; (4) the terms and conditions of the Agreement and whether
the Reorganization would result in dilution of AC Fund shareholder interests;
(5) the advantages of eliminating the competition and duplication of effort
inherent in marketing two funds having similar investment objectives, in
addition to the economies of scale realized through the combination of the two
funds; (6) the compatibility of the funds' service features available to
shareholders, including the retention of applicable holding periods and exchange
privileges; (7) the costs estimated to be incurred by the respective funds as a
result of the Reorganization; and (8) the anticipated tax consequences of the
Reorganization. Based upon these and other factors, the AC Board unanimously
determined that the Reorganization is in the best interests of the shareholders
of the AC Fund.
 
B. RISK FACTORS
 
NATURE OF INVESTMENT
 
  Each of the VK Fund and the AC Fund invest primarily in a portfolio of tax
exempt municipal securities. Investment in either of the VK Fund or the AC Fund
may not be appropriate for all investors.
 
  Certain investment policies and practices of the VK Fund involve special
risks. Investment in municipal securities involves risks of fluctuation in value
as a result of changes in market rates of interest and actual or perceived
changes in the credit quality of the issuer. To the extent such securities are
"revenue" securities and not "general obligation" securities and therefore not
backed by the full faith and credit of the issuer, changes in the ability of the
specific revenue source to satisfy the
 
                                       17
<PAGE>   23
 
obligations of the securities may also affect market value. Investment in lower
grade municipal securities involves greater credit risk and market risk. Such
securities may be less liquid, more volatile and have less publicly available
information as compared to higher grade income securities. Other investment
policies and practices also involve special risks, including investment in
municipal securities whose rates of interest vary inversely with market rates of
interest, investment in municipal lease obligations that have
"non-appropriation" clauses, the use of options, futures and interest rate
transactions, the use of when issued and delayed delivery transactions and
investment in municipal securities that pay interest that is subject to the
federal alternative minimum tax. For a more complete discussion of the risks of
an investment in the VK Fund, see the sections of the VK Fund Prospectus
entitled "Investment Objective and Policies," "Municipal Securities,"
"Investment Practices" and "Special Considerations Regarding the Fund."
 
CHANGES IN CERTAIN INVESTMENT PRACTICES
 
  Both the VK Fund and the AC Fund may engage in certain options and financial
futures transactions, although the VK Fund may also engage in interest rate
transactions such as swaps, caps, floors or collars. The VK Fund also has
greater levels of flexibility in pursuing its investment objectives through the
ability to invest up to 80% of its total assets in tax-exempt municipal
securities rated BBB or better by S&P or Baa or better by Moody's, while the AC
Fund must have at least 50% of its assets invested in tax-exempt municipal
securities rated A or better by S&P and by Moody's. Further, the VK Fund may
also invest up to 20% of its assets in tax-exempt municipal securities rated
between BB and B- (inclusive) by S&P and between Ba and B3 (inclusive) by
Moody's, while the AC Fund may not invest in any securities rated below B by S&P
and Moody's. Such lower rated or unrated securities are commonly referred to as
"junk bonds" and are regarded by Moody's and S&P as predominantly speculative
with respect to the capacity to pay interest or repay principal in accordance
with their terms. Accordingly, although the VK Fund has greater flexibility to
achieve its investment objective, it also may incur additional risks. For a
complete description of the AC Fund's investment practices, see the section in
the AC Fund's Prospectus entitled "Investment Practices" and "Investment
Objective and Policies" and the section of the VK Fund's Statement of Additional
Information entitled "Additional Investment Considerations."

  As series of the VKAC Tax Free Trust, a Delaware business trust, and as a
Delaware business trust, the operations of the VK Fund and the AC Fund are
governed by their respective Agreements and Declarations of Trust (each, a
"Declaration"), their respective Bylaws and applicable Delaware law.
 
D. THE PROPOSED REORGANIZATION
 
  The material features of the Agreement are summarized below. This summary does
not purport to be complete and is subject in all respects to the provisions of,
and is qualified in its entirety by reference to, the Agreement, a copy of which
is attached hereto as Exhibit A. The affirmative vote of a majority of the
outstanding shares entitled to vote is required to approve the Agreement at a
meeting of shareholders at which a quorum is present.
 
TERMS OF THE AGREEMENT
 
  Pursuant to the Agreement, the VK Fund series of the VKAC Tax Free Trust would
acquire all of the assets and the liabilities of the AC Fund on the date of the
Closing in exchange for Class A, B and C Shares of the VK Fund.
 
  Subject to AC Fund shareholder approval of the Reorganization, the closing
(the "Closing") will occur within 15 business days after the later of the
receipt of all necessary regulatory approvals and the final adjournment of the
Special Meeting or
 
                                       19
<PAGE>   25
 
such later date as soon as practicable thereafter as the VK Fund and the AC Fund
may mutually agree.
 
  On the date of Closing, the AC Fund will transfer to the VK Fund all of the
assets and liabilities of the AC Fund. The VKAC Tax Free Trust will in turn
transfer to the AC Fund a number of Class A, B and C Shares of the VK Fund
approximately equal in value to the value of the net assets of the AC Fund
transferred to the VK Fund as of the date of Closing, as determined in
accordance with the valuation method described in the VK Fund's then current
prospectus. In order to minimize any potential for undesirable federal income
and excise tax consequences in connection with the Reorganization, the VK Fund
and the AC Fund may distribute on or before the Closing all or substantially all
of their respective undistributed net investment income (including net capital
gains) as of such date.
 
  The AC Fund expects to distribute the Class A, B and C Shares of the VK Fund
to the shareholders of the AC Fund promptly after the Closing and then dissolve
pursuant to a plan of dissolution adopted by the AC Board.
 
  The AC Fund and the VKAC Tax Free Trust have made certain standard
representations and warranties to each other regarding their capitalization,
status and conduct of business.
 
  Unless waived in accordance with the Agreement, the obligations of the parties
to the Agreement are conditioned upon, among other things:
 
    1.  the approval of the Reorganization by the AC Fund's shareholders;
 
    2.  the absence of any rule, regulation, order, injunction or proceeding
        preventing or seeking to prevent the consummation of the transactions
        contemplated by the Agreement;
 
    3.  the receipt of all necessary approvals, registrations and exemptions
        under federal and state laws;
 
    4.  the truth in all material respects as of the Closing of the
        representations and warranties of the parties and performance and
        compliance in all material respects with the parties' agreements,
        obligations and covenants required by the Agreement;
 
    5.  the effectiveness under applicable law of the registration statement of
        the VK Fund of which this Proxy Statement/Prospectus forms a part and
        the absence of any stop orders under the Securities Act pertaining
        thereto; and
 
    6.  the receipt of opinions of counsel relating to, among other things, the
        tax free nature of the Reorganization.
 
                                       20
<PAGE>   26
 
  The Agreement may be terminated or amended by the mutual consent of the
parties either before or after approval thereof by the shareholders of the AC
Fund, provided that no such amendment after such approval shall be made if it
would have a material adverse affect on the interests of AC Fund shareholders.
The Agreement may also be terminated by the non-breaching party if there has
been a material misrepresentation, material breach of any representation or
warranty, material breach of contract or failure of any condition to Closing.
 
  The AC Board recommends that you vote to approve the Reorganization, as it
believes the Reorganization is in the best interests of the AC Fund's
shareholders and that the interests of the AC Fund's existing shareholders will
not be diluted as a result of consummation of the proposed Reorganization.
 
DESCRIPTION OF SECURITIES TO BE ISSUED
 
  SHARES OF BENEFICIAL INTEREST
 
  Beneficial interests in the VK Fund being offered hereby are represented by
transferable Class A, B and C Shares, par value $.01 per share. The VKAC Tax
Free Trust's Declaration permits the trustees, as they deem necessary or
desirable, to create one or more separate investment portfolios and to issue a
separate series of shares for each portfolio and, subject to compliance with the
Act, to further sub-divide the shares of a series into one or more classes of
shares for such portfolio.
 
  VOTING RIGHTS OF SHAREHOLDERS
 
  Holders of shares of the VK Fund are entitled to one vote per share on matters
as to which they are entitled to vote; however, separate votes generally are
taken by each series on matters affecting an individual series. The Declaration
of VKAC Tax Free Trust and the Declaration of AC Fund are substantially
identical, except that the Declaration of the VKAC Tax Free Trust permits the VK
Board or shareholders to remove a trustee with or without cause by the act of
two-thirds of such trustees or shareholders, respectively. The Declaration of
the AC Fund permits (i) the AC Board to remove a trustee with cause by the act
of two-thirds of the trustees and (ii) shareholders holding a majority of the
shares of each series outstanding to remove a trustee with or without cause. The
Declaration of the AC Fund also requires the approval of 80% of the trustees in
office or majority vote of the shares of each series then outstanding to amend
these provisions.
 
  Each of the VK Fund and the AC Fund operate as a diversified, open-end
management investment company registered with the SEC under the Act. Therefore,
in addition to the specific voting rights described above, shareholders of the
VK Fund, as well as shareholders of the AC Fund, are entitled, under current
law, to vote with respect to certain other matters, including changes in
fundamental
 
                                       21
<PAGE>   27
 
investment policies and restrictions and the ratification of the selection of
independent auditors. Moreover, under the Act, shareholders owning not less than
10% of the outstanding shares of the AC Fund or VK Fund may request that the
respective board of trustees call a shareholders' meeting for the purpose of
voting upon the removal of trustee(s).
 
CONTINUATION OF SHAREHOLDER ACCOUNTS AND PLANS; SHARE CERTIFICATES
 
  If the Reorganization is approved, the VK Fund will establish an account for
each AC Fund shareholder containing the appropriate number of Shares of the VK
Fund. The shareholder services and shareholder programs of the VK Fund and the
AC Fund have already been conformed as part of the Consolidation. Shareholders
of the AC Fund who are accumulating AC Fund shares under the dividend
reinvestment plan, or who are receiving payment under the systematic withdrawal
plan with respect to AC Fund shares, will retain the same rights and privileges
after the Reorganization in connection with the VK Fund Class A, B or C Shares
received in the Reorganization through substantially similar plans maintained by
the VK Fund. Van Kampen American Capital Trust Company will continue to serve as
custodian for the assets of AC Fund shareholders held in IRA accounts after the
Reorganization. Such IRA investors will be sent appropriate documentation to
confirm Van Kampen American Capital Trust Company's custodianship.
 
  It will not be necessary for shareholders of the AC Fund to whom certificates
have been issued to surrender their certificates. Upon dissolution of the AC
Fund, such certificates will become null and void.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a general discussion of the material federal income tax
consequences of the Reorganization to shareholders of the AC Fund and
shareholders of the VK Fund. It is based upon the Code, legislative history,
Treasury regulations, judicial authorities, published positions of the Internal
Revenue Service (the "Service") and other relevant authorities, all as in effect
on the date hereof and all of which are subject to change or different
interpretations (possibly on a retroactive basis). This summary is limited to
shareholders who hold their AC Fund shares as capital assets. No advance rulings
have been or will be sought from the Service regarding any matter discussed in
this Proxy Statement/Prospectus. Accordingly, no assurances can be given that
the Service could not successfully challenge the intended federal income tax
treatment described below. Shareholders should consult their own tax advisors to
determine the specific federal income tax consequences of all transactions
relating to the Reorganization, as well as the effects of state, local and
foreign tax laws.
 
  The Reorganization is intended to qualify as a "reorganization" within the
meaning of Section 368(a)(1) of the Code. It is a condition to closing that the
 
                                       22
<PAGE>   28
 
VKAC Tax Free Trust and the AC Fund receive an opinion from O'Melveny & Myers
substantially to the effect that for federal income tax purposes:
 
  1. The acquisition by the VK Fund of the assets of the AC Fund in exchange
solely for Class A, B and C Shares of the VK Fund and the assumption by the VK
Fund of the liabilities of the AC Fund will qualify as a tax-free reorganization
within the meaning of Section 368(a)(1) of the Code.
 
  2. No gain or loss will be recognized by the AC Fund or the VK Fund upon the
transfer to the VK Fund of the assets of the AC Fund in exchange solely for the
Class A, B and C Shares of the VK Fund and the assumption by the VK Fund of the
liabilities of the AC Fund.
 
  3. The VK Fund's basis in the AC Fund assets received in the Reorganization
will, in each instance, equal the basis in such assets in the hands of the AC
Fund immediately prior to the transfer, and the VK Fund's holding period of such
assets will, in each instance, include the period during which the assets were
held by the AC Fund.
 
  4. No gain or loss will be recognized by the shareholders of the AC Fund upon
the exchange of their shares of the AC Fund for the Class A, B or C Shares,
respectively, of the VK Fund.
 
  5. The aggregate tax basis in the Class A, B and C Shares of the VK Fund
received by the shareholders of the AC Fund will be the same as the aggregate
tax basis of the shares of the AC Fund surrendered in exchange therefor.
 
  6. The holding period of the Class A, B and C Shares of the VK Fund received
by the shareholders of the AC Fund will include the holding period of the shares
of the AC Fund surrendered in exchange therefor if such surrendered shares of
the AC Fund are held as capital assets by such shareholder.
 
  In rendering its opinion, O'Melveny & Myers may rely upon certain
representations of the management of the AC Fund and the VKAC Tax Free Trust and
assume that the Reorganization will be consummated as described in the Agreement
and that redemptions of shares of the AC Fund occurring prior to the Closing
will consist solely of redemptions in the ordinary course of business.
 
  The VK Fund intends to be taxed under the rules applicable to regulated
investment companies as defined in Section 851 of the Code, which are the same
rules currently applicable to the AC Fund and its shareholders.

  The total return figures above assume reinvestment of all dividends and
distributions. They are not necessarily indicative of future results. The
performance of a fund is a result of conditions in the securities markets,
portfolio management and operating expenses. Although information such as that
shown above is useful in reviewing a fund's performance and in providing some
basis for comparison with other investment alternatives, it should not be used
for comparison with other investments using different reinvestment assumptions
or time periods.

investment objective, policies and restrictions of the VK Fund, see "Summary --
Comparisons of the VK Fund and AC Fund" and the VK Fund Prospectus accompanying
this Proxy Statement/Prospectus. Approval of the Reorganization will constitute
approval of amendments to any of the fundamental investment restrictions of the

solely for the purpose of and to the extent necessary for, consummation of the
Reorganization.

B. SHAREHOLDER PROPOSALS
 
  As a general matter, the AC Fund does not intend to hold future regular annual
or special meetings of shareholders unless required by the Act. Any shareholder
who wishes to submit proposals for consideration at a meeting of shareholders of
the VK Fund should send such proposal to the VK Fund at One Parkview Plaza,
Oakbrook Terrace, Illinois 60181. To be considered for presentation at a
shareholders' meeting rules promulgated by the SEC require that, among other
things, a shareholder's proposal must be received at the offices of the VK Fund
a reasonable time before a solicitation is made. Timely submission of a proposal
does not necessarily mean that such proposal will be included.
 
                      VOTING INFORMATION AND REQUIREMENTS
 
  Each valid proxy given by a shareholder of the AC Fund will be voted by the
persons named in the proxy in accordance with the designation on such proxy on
the Reorganization proposal and as the persons named in the proxy may determine
on
 
                                       27
<PAGE>   33
 
such other business as may come before the Special Meeting on which shareholders
are entitled to vote. If no designation is made, the proxy will be voted by the
persons named in the proxy as recommended by the AC Board "FOR" approval of the
Reorganization.
 
  Shareholders who execute proxies may revoke them at any time before they are
voted by filing with the Fund a written notice of revocation, by delivering a
duly executed proxy bearing a later date, or by attending the Special Meeting
and voting in person.
 
  The giving of a proxy will not affect your right to vote in person if you
attend the Special Meeting and wish to do so.
 
  The presence in person or by proxy of the holders of a majority of the
outstanding shares entitled to vote is required to constitute a quorum at the
Special Meeting. APPROVAL OF THE REORGANIZATION WILL REQUIRE THE FAVORABLE VOTE
OF THE HOLDERS OF A MAJORITY OF THE OUTSTANDING SHARES OF THE AC FUND ENTITLED
TO VOTE AT THE SPECIAL MEETING AT WHICH A QUORUM IS CONSTITUTED. Shares not
voted with respect to a proposal due to an abstention or broker non-vote will be
deemed votes not cast with respect to such proposal, but such shares will be
deemed present for quorum purposes.
 
  In the event that sufficient votes in favor of the Reorganization are not
received by the scheduled time of the Special Meeting, the persons named in the
proxy may propose and vote in favor of one or more adjournments of the Special
Meeting to permit further solicitation of proxies. If sufficient shares were
present to constitute a quorum, but insufficient votes had been cast in favor of
the Reorganization to approve it, proxies would be voted in favor of adjournment
only if the AC Board determined that adjournment and additional solicitation was
reasonable and in the best interest of the shareholders of the AC Fund, taking
into account the nature of the proposal, the percentage of the votes actually
cast, the percentage of negative votes, the nature of any further solicitation
that might be made and the information provided to shareholders about the
reasons for additional solicitation. Any such adjournment will require the
affirmative vote of the holders of a majority of the outstanding shares voted at
the session of the Special Meeting to be adjourned.
 
  Proxies of shareholders of the AC Fund are solicited by the AC Board. The cost
of solicitation will be paid by the VK Fund after the Reorganization if the
Reorganization is completed. If the Reorganization is not completed VKAC will
bear the costs associated with the Reorganization. In order to obtain the
necessary quorum at the Special Meeting, additional solicitation may be made by
mail, telephone, telegraph or personal interview by representatives of the AC
Fund, the
 
                                       28
<PAGE>   34
 
VK Adviser or VKAC, or by dealers or their representatives. In addition, such
solicitation servicing may also be provided by Applied Mailing Systems, a
solicitation firm located in Boston, Massachusetts, at a cost estimated to be
approximately $4,604, plus reasonable expenses.

transactions contemplated thereby contravene the VKM Trust's Declaration of 
Trust, or, to the best of their knowledge, violate any provision of any 
statute or any published regulation or any judgment or order disclosed to us 
by the VKM Trust as being applicable to the VKM Trust or the VKM Fund;
(vi) to the best of their knowledge based solely on the certificate of an
appropriate officer of the VKM Trust attached hereto, there is no pending or
threatened litigation which would have the effect of prohibiting any material
business practice or the acquisition of any material property or the conduct of
any material business of the VKM Fund or might have a material adverse effect
on the value of any assets of the VKM Fund; (vii) the VKM Fund's Shares have
been duly authorized and upon issuance thereof in accordance with this
Agreement will, subject to certain matters regarding the liability of a
shareholder of a Delaware trust, be validly issued, fully paid and
non-assessable; (viii) except as to financial statements and schedules and
other financial and statistical data included or incorporated by reference
therein and subject to usual and customary qualifications with respect to Rule
10b-5 type opinions, as of the effective date of the Registration Statement
filed pursuant to the Agreement, the portions thereof pertaining to VKM Trust
and the VKM Fund comply as to form in all material respects with the
requirements of the Securities Act, the Securities Exchange Act and the 1940
Act and the rules and regulations of the Commission thereunder and no facts
have come to counsel's attention which would cause them to believe that as of
the effectiveness of the portions of the Registration Statement applicable to
VKM Trust and VKM Fund, the Registration Statement contained any untrue
statement of a material fact or omitted to state any material fact required to
be stated therein or necessary to make the statements therein not misleading;
and (ix) to the best of their knowledge and information and subject to the
qualifications set forth below, the execution and delivery by the VKM Trust of
the Agreement and the consummation of the transactions therein contemplated do
not require, under the laws of the States of Delaware or Illinois or the
federal laws of the United States, the consent, approval, authorization,
registration, qualification or order of, or filing with, any court or
governmental agency or body (except such as have been obtained). Counsel need
express no opinion, however, as to any such consent, approval, authorization,
registration, qualification, order or filing (a) which may be required as a
result of the involvement of other parties to the Agreement in the transactions
contemplated by the Agreement because of their legal or regulatory status or
because of any other facts specifically pertaining to them; (b) the absence of
which does not deprive the AC Trust or the AC Fund of any material
benefit under the Agreement; or (c) which can be readily obtained without
significant delay or expense to the AC Trust or  the AC Fund, without loss to
the AC Trust or the AC Fund of any material benefit under the Agreement and
without any material adverse effect on the AC Trust or the AC Fund  during the
period such consent, approval, authorization, registration,  qualification or
order was obtained. The foregoing opinion relates only to consents, approvals,
authorizations, registrations, qualifications, orders or filings under (a) laws
which are specifically referred to in this opinion, (b) laws of the States of
Delaware and Illinois and the United States of America which, in counsel's
experience, are normally applicable to transactions of the type provided for in
the Agreement and (c) court orders and judgments disclosed to us by the VKM
Trust in connection with this opinion. In addition, although counsel need not
specifically considered the possible applicability to the VKM Trust of any
other laws, orders or judgments, nothing has come to their attention in
connection with their representation of the VKM Trust and the VKM Fund in this
transaction that has caused them to conclude that any other consent, approval,
authorization, registration, qualification, order or filing is required.
 
     H. OFFICER CERTIFICATES. The AC Fund shall have received a certificate of
an authorized officer of the VKM Trust, dated as of the Closing Date, certifying
that the representations and warranties set forth in Section 5 are true and
correct on the Closing Date, together with certified copies of the resolutions
adopted by the Board of Trustees shall be furnished to the AC Trust.

Agreement in the transactions contemplated by the Agreement because of their

     11. SURVIVAL OF WARRANTIES AND INDEMNIFICATION.
 
     (A) SURVIVAL. The representations and warranties included or provided for
herein, or in the Schedules or other instruments delivered or to be delivered
pursuant hereto, shall survive the Closing Date for a three year period except
that any representation or warranty with respect to taxes shall survive for the
expiration of the statutory period of limitations for assessments of tax
deficiencies as the same may be extended from time to time by the taxpayer. The
covenants and agreements included or provided for herein shall survive and be
continuing obligations in accordance with their terms. The period for which a
representation, warranty, covenant or agreement survives shall be referred to
hereinafter as the "Survival Period." Notwithstanding anything set forth in the
immediately preceding sentence, the VKM Trust's and the AC Fund's right to seek
indemnity pursuant to this Agreement shall survive for a period of ninety (90)
days beyond the expiration of the Survival Period of the representation,
warranty, covenant or agreement upon which indemnity is sought. In no event
shall the VKM Trust or the AC Fund be obligated to indemnify the other if
indemnity is not sought within ninety (90) days of the expiration of the
applicable Survival Period.
 
     (B) INDEMNIFICATION. Each party (an "Indemnitor") shall indemnify and hold
the other and its officers, directors, agents and persons controlled by or
controlling any of them (each an "Indemnified Party") harmless from and against
any and all losses, damages, liabilities, claims, demands, judgments,
settlements, deficiencies, taxes, assessments, charges, costs and expenses of   
any nature whatsoever (including reasonable attorneys' fees) including amounts
paid in satisfaction of judgments, in compromise or as fines and penalties, and
counsel fees reasonably incurred by such Indemnified Party in connection with
the defense or disposition of any claim, action, suit or other proceeding,
whether civil or criminal, before any court or administrative or investigative
body in which such Indemnified Party may be or may have been involved as a
party or otherwise or with which such Indemnified Party may be or may have been
threatened, (collectively, the "Losses"): arising out of or related to any
claim of a breach of any representation, warranty or covenant made herein by
the Indemnitor; provided, however, that no Indemnified Party shall be
indemnified hereunder against any Losses arising directly
 
                                       13
<PAGE>   48
 
from such Indemnified Party's (i) willful misfeasance, (ii) bad faith, (iii)
gross negligence or (iv) reckless disregard of the duties involved in the
conduct of such Indemnified Party's position.
 
     (C) INDEMNIFICATION PROCEDURE. The Indemnified Party shall use its best
efforts to minimize any liabilities, damages, deficiencies, claims, judgments,
assessments, costs and expenses in respect of which indemnity may be sought
hereunder. The Indemnified Party shall given written notice to Indemnitor within
the earlier of ten (10) days of receipt of written notice to Indemnitor or
thirty (30) days from discovery by Indemnified Party of any matters which may
give rise to a claim for indemnification or reimbursement under this Agreement.
The failure to give such notice shall not affect the right of Indemnified Party
to indemnity hereunder unless such failure has materially and adversely affected
the rights of the Indemnitor; provided that in any event such notice shall have
been given prior to the expiration of the Survival Period. At any time after ten
(10) days from the giving of such notice, Indemnified Party may, at its option,
resist, settle or otherwise compromise, or pay such claim unless it shall have
received notice from Indemnitor that Indemnitor intends, at Indemnitor's sole
cost and expense, to assume the defense of any such matter, in which case
Indemnified Party shall have the right, at no cost or expense to Indemnitor, to
participate in such defense. If Indemnitor does not assume the defense of such
matter, and in any event until Indemnitor states in writing that it will assume
the defense, Indemnitor shall pay all costs of Indemnified Party arising out of
the defense until the defense is assumed; provided, however, that Indemnified
Party shall consult with Indemnitor and obtain Indemnitor's consent to any
payment or settlement of any such claim. Indemnitor shall keep Indemnified Party
fully apprised at all times as to the status of the defense. If Indemnitor does
not assume the defense, Indemnified Party shall keep Indemnitor apprised at all
times as to the status of the defense. Following indemnification as provided for
hereunder, Indemnitor shall be subrogated to all rights of Indemnified Party
with respect to all third parties, firms or corporations relating to the matter
for which indemnification has been made.
 
     12. SURVIVAL
 
     The provisions set forth in Sections 10, 11 and 16 hereof shall survive the
termination of this Agreement for any cause whatsoever.

                     MANAGEMENT'S DISCUSSION OF VK FUND AND
                              AC FUND PERFORMANCE
 
  Management's Discussion of VK Fund Performance as of the Annual Report dated
December 31, 1995.
 
  The VK Fund's performance during its fiscal year ended December 31, 1994, was
impacted by rising rates and inflation concerns. The Federal Reserve Board (the
"Fed") raised the Fed Funds rate--the rate banks charge each other for overnight
loans--from 3 percent to 5.5 percent during 1994, pushing interest rates to
their highest level in three years. As rates rose, so did yields on fixed-income
securities. The yield on 30-year Treasury bonds, for example, began the year at
6.35 percent and increased to a high of 8.16 percent, before ending the year at
7.89 percent. However, since yields and prices move in opposite directions, this
had a negative impact on prices of fixed-income securities. Additionally, low
interest rates during the early part of the year prompted many issuers to refund
their debt, and the income from the higher-yielding issues that were refunded
could not be replaced in the current environment.
 
  Equity investors, meanwhile, worried that higher interest rates would increase
corporate borrowing costs and depress earnings. These factors combined to push
the stock market down during much of the year, and resulted in the Standard &
Poor's 500-Stock Index achieving a total return for the year of just 1.36
percent. This index is a broad-based, unmanaged indicator of general stock
market performance.
 
  The Fed remains concerned about inflation, and probably will raise interest
rates again this year. Many economists expect inflation to increase in 1995 at
an annual rate of about 3.5 percent, although consumer prices, which are a key
inflation measure, rose only 2.7 percent last year. Analysts point to a steady
increase in consumer spending, especially for durable goods like automobiles and
major appliances, as an indication that the inflation rate will rise.
Additionally, the national unemployment rate is below 6%, which could force
employers to pay more for employees. Labor costs account for about two-thirds of
what consumers pay for goods and services.
 
  Clearly, consumers are feeling better about the economy. The consumer
confidence index reached a four-and-a-half year high in December, rising to
102.2 from 100.4 in November. Consumer confidence was boosted by the increase in
jobs and personal income.

    1994, and does not include payment of the maximum sales charge (4.65% for A
    shares) or continent deferred sales charge (4% for B shares; 1% for C
    shares). Effective January 16, 1995, the maximum sales charge for Class A
    shares was changed to 4.75%. Had certain expenses of the VK Fund not been

                     MUNICIPAL BOND INDEX
                     (August 1990 through December 1994)
 

  The following graph compares the value of an investment in the VK Fund's
Class A shares with the value of an investment in the Lehman Brothers Municipal
Bond Index from August 1990 through December 1994, the last trading day of
fiscal year 1994, based upon a $10,000 investment in Class A shares of the VK
Fund and in the securities comprising such index as of August 1990. The
approximate values of such an investment in each fiscal year were: 1990: Class
A shares of VK Fund -- $11,150, Lehman Index -- $11,550; 1991: Class A shares
of VK Fund -- $11,150, Lehman Index -- $11,550; 1992: Class A shares of VK Fund
- -- $12,200, Lehman Index -- $12,550; 1993: Class A shares of VK Fund -- 
$13,700, Lehman Index -- $14,100; 1994: Class A shares of VK Fund -- $12,850, 
Lehman Index -- $13,375.

  Performance of Class B and C Shares may vary from the Class A Shares
illustrated above due to the distribution and administrative expense
differentials applicable to these classes.
 
  The Index is unmanaged and expense free. Its performance does not reflect
transaction and other costs applicable to the Fund's actively managed portfolio.
 
  Past performance is not predictive of future performance.
 
  Management's Discussion of AC Fund Performance as of the Annual Report dated
September 30, 1994.
 
  The AC Fund invests in intermediate and long-term municipal bonds with the
objective of providing current interest income exempt from federal income taxes
as is consistent with the preservation of capital. During the reporting period
that ended September 30, 1994, the AC Fund's performance was negatively affected
by repeated increases in interest rates.
 
  Accelerating economic activity and the resulting fears of inflation created a
challenging environment for municipal bonds. Although the Federal Reserve Board
(the "Fed") raised short-term interest rates five times during the reporting
period, for a total increase of 1.75 percentage points, the economy continued to
grow. In August (the latest month for which figures were available) new factory
orders increased 4.4%, the largest gain in nearly two years and the 11th
increase in the previous 13 months. This report and others of a variety of
economic indicators generated renewed fears of both inflation and additional
interest-rate increases.
<PAGE>   53
 
  As these fears grew, municipal bond yields rose steadily. After hitting a
12-month low of 5.41% on October 14, 1993, the yield on the Bond Buyer Index of
25 Revenue Bonds, an unmanaged municipal bond index, rose to a 12-month high of
6.70% on September 29, 1994. The yield on 10-year Treasury notes followed a
similar pattern, rising from a 12-month low of 5.79% on October 15, 1993, to a
12-month high of 7.82% on September 29, 1994. Bond yields and prices move
inversely, so the steady rise in yields pushed down municipal bond prices. The
bond market has built a very high inflation premium into rates on long-term
bonds. Since Treasuries historically have offered a "real" return -- the return
after inflation -- of around 2.5%, the yield at the end of September meant
investors were anticipating inflation to hit an annualized rate of about 5% even
though many forecasters have predicted the inflation rate in 1995 will be
between 3% and 3.5%.
 
  As a result of rising interest rates, there was a significant decline in
refundings. Refundings occur when municipalities issue new lower-yielding bonds
to replace existing higher-yielding bonds. As interest rates rose, this reduced
the incentive to refund existing debt. As a result, the dollar value of
refundings during the first nine months of 1994 declined 43.5%, including a 68%
decline in September compared with September 1993. Normally, if the supply
decreases while demand remains steady, prices will rise. However, demand for
municipal bonds declined during the reporting period along with the supply, so
prices fell.
 
  As the interested rate environment changed, the AC Fund placed primary
emphasis on its federally tax-exempt dividend, since that is the component of
total return that usually is of greatest importance to shareholders. (A portion
of the income may be subject to state and local taxes and, if applicable, may be
subject to the federal alternative minimum tax.) To provide dividend income, the
AC Fund focused on longer-term bonds, which offer a higher coupon rate. The
coupon rate is the percentage of a bond's face value that is paid to the AC Fund
annually as interest. So, the AC Fund continued to selectively purchase
longer-term revenue bonds, since revenue bonds generally offer a higher interest
rate than general obligation bonds. The average maturity of the portfolio at the
end of the reporting period was a little more than 20 years.
 
  Within this investment strategy, the AC Fund has maintained a high quality
rating in its portfolio holdings.
 
  All classes of shares of the AC Fund at net asset value (without a sales
charge) outperformed the Lehman Brothers Municipal Bond Index during the
reporting period. Class A shares of the AC Fund achieved a total return at net
asset value of -1.33%, including reinvestment of dividends totalling $.5745 per
share. Class B shares achieved a total return at net asset value of -2.13%,
including reinvestment of dividends totalling $.4905 per share. Class C shares
achieved a total return at net asset value of -2.03%, including reinvestment of
dividends totalling $.4905 per share.
<PAGE>   54
 
  The Lehman Brothers Municipal Bond Index, a broad-based, unmanaged index of
municipal bonds, achieved a total return of -2.44% for the 12 months ended
September 30, 1994. The index does not reflect any commissions or fees that
would be paid by an investor purchasing the securities it represents.

(Continued from previous page.)
 
    The Fund currently offers three classes of its shares (the "Alternative
Sales Arrangements") which may be purchased at a price equal to their net asset
value per share, plus sales charges which, at the election of the investor, may
be imposed (i) at the time of purchase (the "Class A Shares") or (ii) on a
contingent deferred basis (Class A Share accounts over $1 million, "Class B
Shares" and "Class C Shares"). The Alternative Sales Arrangements permit an
investor to choose the method of purchasing shares that is more beneficial to
the investor, taking into account the amount of the purchase, the length of time
the investor expects to hold the shares and other circumstances.
 
    Each class of shares pays ongoing distribution and service fees at an
aggregate annual rate of (i) for Class A Shares, up to 0.25% of the Fund's
average daily net assets attributable to the Class A Shares, (ii) for Class B
Shares, up to 1.00% of the Fund's average daily net assets attributable to the
Class B Shares and (iii) for Class C Shares up to 1.00% of the Fund's average
daily net assets attributable to the Class C Shares. Investors should understand
that the purpose and function of the deferred sales charge and the distribution
and service fees with respect to the Class A Share accounts over $1 million,
Class B Shares and Class C Shares are the same as those of the initial sales
charge and distribution and service fees with respect to the Class A Share
accounts below $1 million. Each share of the Fund represents an identical
interest in the investment portfolio of the Fund and has the same rights, except
that (i) each class of shares bears those distribution fees, service fees and
administrative expenses applicable to the respective class of shares as a result
of its sales arrangements, which will cause the different classes of shares to
have different expense ratios and to pay different rates of dividends, (ii) each
class has exclusive voting rights with respect to those provisions of the Fund's
Rule 12b-1 distribution plan which relate only to such class and (iii) the
classes have different exchange privileges. Class B Shares automatically will
convert to Class A Shares six years after the end of the calendar month in which
the investor's order to purchase was accepted, in the circumstances and subject
to the qualifications described in this Prospectus. See "Alternative Sales
Arrangements" and "Purchase of Shares."

                               PROSPECTUS SUMMARY
- ------------------------------------------------------------------------------
 
THE FUND.  Van Kampen American Capital Municipal Income Fund (the "Fund") is a
separate diversified series of Van Kampen American Capital Tax Free Trust (the
"Trust"), an open-end management investment company organized as a Delaware
business trust. See "The Fund."
 
MINIMUM PURCHASE.  $500 minimum initial investment for each class of shares and
$25 minimum for each subsequent investment for each class of shares (or less as
described under "Purchase of Shares").
 
INVESTMENT OBJECTIVE.  The Fund's investment objective is to provide investors
with a high level of current income exempt from federal income tax, consistent
with preservation of capital.
 
INVESTMENT POLICY.  The Fund seeks to achieve its investment objective by
investing at least 80% of its assets in a diversified portfolio of tax-exempt
municipal securities rated investment grade at the time of investment.
Investment grade securities are securities rated BBB or higher by Standard &
Poor's Ratings Group ("S&P") or Baa or higher by Moody's Investors Service, Inc.
("Moody's") in the case of long-term obligations, and have equivalent ratings in
the case of short-term obligations. Up to 20% of the Fund's total assets may be
invested in tax-exempt municipal securities rated, at the time of investment,
between BB and B-(inclusive) by S&P or between Ba and B3 (inclusive) by Moody's
(or equivalently rated short-term obligations) and unrated tax-exempt municipal
securities that the Fund's investment adviser believes are of comparable
quality. See "Special Considerations Regarding the Fund."
 
  Municipal securities in which the Fund may invest include fixed and variable
rate securities, municipal notes, municipal leases, tax exempt commercial paper,
custodial receipts, participation certificates and derivative municipal
securities the terms of which include elements of, or are similar in effect to,
certain Strategic Transactions (as defined herein) in which the Fund may engage.
The Fund may invest up to 15% of its total assets in derivative variable rate
securities such as inverse floaters, whose rates vary inversely with changes in
market rates of interest or range or capped floaters, whose rates are subject to
periodic of lifetime caps. There is no assurance that the Fund will achieve its
investment objective. Debt securities rated below investment grade are commonly
referred to as "junk bonds." The net asset value per share of the Fund may
increase or decrease depending on changes in interest rates and other factors
affecting the municipal credit markets. See "Investment Objective and Policies."
 
INVESTMENT PRACTICES.  The Fund also may use various investment techniques
including engaging in risk management transactions and entering into when-issued
or delayed delivery transactions and various strategic transactions. Such
transactions entail certain risks. See "Municipal Securities" and "Investment
Practices." The Fund may invest a substantial portion of its assets in municipal
securities that
 
                                        4
<PAGE>   60
 
pay interest that is subject to the federal alternative minimum tax. The Fund
may not be a suitable investment for investors who are already subject to the
federal alternative minimum tax or who would become subject to the federal
alternative minimum tax as a result of an investment in the Fund. See "Tax
Status."
 
INVESTMENT RESULTS.  The investment results of the Fund since its inception are
shown in the table of "Financial Highlights."
 
ALTERNATIVE SALES ARRANGEMENTS.  The Alternative Sales Arrangements permit an
investor to choose the method of purchasing shares that is more beneficial to
the investor, taking into account the amount of the purchase, the length of time
the investor expects to hold the shares and other circumstances. Investors
should consider such factors together with the amount of sales charges and
accumulated distribution and service fees with respect to each class of shares
that may be incurred over the anticipated duration of their investment in the
Fund. To assist investors in making this determination, the table under the
caption "Annual Fund Operating Expenses and Example" sets forth examples of the
charges applicable to each class of shares.
 
  The Fund currently offers three classes of its shares which may be purchased
at a price equal to their net asset value per share plus sales charges which, at
the election of the investor, may be imposed either (i) at the time of purchase
("Class A Shares") or (ii) on a contingent deferred basis (Class A Share
accounts over $1 million, "Class B Shares," and "Class C Shares"). Class A Share
accounts over $1 million or otherwise subject to a contingent deferred sales
charge ("CDSC"), Class B Shares, and Class C Shares sometimes are referred to
herein collectively as "CDSC Shares."
 
  Class A Shares. Class A Shares are subject to an initial sales charge equal to
4.75% of the public offering price (4.99% of the net amount invested), reduced
on investments of $100,000 or more. Class A Shares are subject to ongoing
distribution and service fees at an aggregate annual rate of up to 0.25% of the
Fund's average daily net assets attributable to the Class A Shares. Certain
purchases of Class A Shares qualify for reduced or no initial sales charges and
may be subject to a CDSC.
 
  Class B Shares. Class B Shares do not incur a sales charge when they are
purchased, but are subject to a sales charge if redeemed within six years of
purchase. Class B Shares are subject to a CDSC equal to 4.00% of the lesser of
the then current net asset value or the original purchase price on Class B
Shares redeemed during the first year after purchase, which charge is reduced
each year thereafter. Class B Shares are subject to ongoing distribution and
service fees at an aggregate annual rate of up to 1.00% of the Fund's average
daily net assets attributable to the Class B Shares. Class B Shares
automatically will convert to Class A Shares six years after the end of the
calendar month in which the investor's order to purchase was accepted, in the
circumstances and subject to the qualifications described in this Prospectus.

  Class C Shares. Class C Shares do not incur a sales charge when they are
purchased, but are subject to a sales charge if redeemed within the first year
after purchase. Class C Shares are subject to a CDSC equal to 1.00% of the
lesser of the then current net asset value or the original purchase price on
Class C Shares redeemed within the first year after purchase. Class C Shares are

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

THE FUND
- ------------------------------------------------------------------------------
 
  Van Kampen American Capital Municipal Income Fund (the "Fund") is a separate
diversified series of Van Kampen American Capital Tax Free Trust (the "Trust"),
which is an open-end management investment company, commonly known as a "mutual
fund," organized as a Delaware business trust. Mutual funds sell their shares to
investors and invest the proceeds in a portfolio of securities. A mutual fund
allows investors to pool their money with that of other investors in order to
obtain professional investment management. Mutual funds generally make it
possible for investors to obtain greater diversification of their investments
and to simplify their recordkeeping.
 
  Van Kampen American Capital Investment Advisory Corp. (the "Adviser") provides
investment advisory and administrative services to the Fund. The Adviser and its
affiliates also manage other mutual funds distributed by Van Kampen American
Capital Distributors, Inc. (the "Distributor"). To obtain prospectuses and other
information on any of these other funds, please call the telephone number on the
cover page of the Prospectus.
 
- ------------------------------------------------------------------------------
INVESTMENT OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------
 
  The investment objective of the Fund is to provide investors with a high level
of current income exempt from federal income tax, consistent with preservation
of capital. The Fund's investment objective is a fundamental policy and may not
be changed without shareholder approval. Under normal market conditions, the
Fund invests at least 80% of its total assets in tax-exempt municipal securities
rated investment grade. The Fund's policy with respect to ratings is not a
fundamental policy, and thus may be changed by the Trustees without shareholder
approval. See "Municipal Securities." The Fund intends, however, to maintain at
all times at least 80% of its total assets in tax-exempt municipal securities
rated investment grade or deemed by the investment adviser to be of comparable
quality at the time of investment. Investment grade securities are securities
rated BBB or higher by Standard & Poor's Ratings Group ("S&P") or Baa or higher
by Moody's Investors Service, Inc. ("Moody's") in the case of long-term
obligations, and have equivalent ratings in the case of short-term obligations.
According to published guidelines, securities rated BBB by S&P are regarded by
S&P as having an adequate capacity to pay interest and repay principal. Whereas
such securities normally exhibit adequate protection parameters, adverse
economic conditions or changing circumstances are more likely, in the opinion of
S&P, to lead to a weakened capacity to pay interest and repay principal for debt
in this category than in higher rated categories. According to published
guidelines, securities rated Baa by Moody's are considered by Moody's as medium
grade obligations. Such securities are, in the opinion of Moody's, neither
highly protected nor poorly secured. Interest payments and principal security
appear to Moody's to be adequate for the present but certain
 
                                       12
<PAGE>   68
 
protective elements may be lacking or may be characteristically unreliable over
any great length of time. In the opinion of Moody's they lack outstanding
investment characteristics and in fact have speculative characteristics as well.
 
  Up to 20% of the Fund's total assets may be invested in tax-exempt municipal
securities rated, at the time of investment, between BB and B- (inclusive) by
S&P or between Ba and B3 (inclusive) by Moody's (or equivalently rated
short-term obligations) and unrated tax-exempt securities that the Adviser
considers to be comparable quality. These securities are below investment grade
and are regarded by S&P, on balance, as predominantly speculative with respect
to capacity to pay interest and repay principal in accordance with the terms of
the obligation. While in the opinion of S&P such securities will likely have
some quality and protective characteristics, these are outweighed by large
uncertainties or major risk exposures to adverse conditions. These securities
are regarded by Moody's as generally lacking characteristics of a desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the securities' contract over any long period of time may, in the
opinion of Moody's, be small. Debt securities rated below investment grade are
commonly referred to as "junk bonds." For a description of S&P's and Moody's
ratings see the Statement of Additional Information. From time to time the Fund
temporarily may also invest up to 10% of its assets in tax exempt money market
funds. Such instruments will be treated as investments in municipal securities.
 
  An investment in the Fund may not be appropriate for all investors. The Fund
is not intended to be a complete investment program, and investors should
consider their long-term investment goals and financial needs when making an
investment decision with respect to the Fund. An investment in the Fund is
intended to be a long-term investment and should not be used as a trading
vehicle.
 
- ------------------------------------------------------------------------------
MUNICIPAL SECURITIES
- ------------------------------------------------------------------------------
 
  GENERAL. Tax-exempt municipal securities are debt obligations issued by or on
behalf of the governments of states, territories or possessions of the United
States, the District of Columbia and their political subdivisions, agencies and
instrumentalities, certain interstate agencies and certain territories of the
United States, the interest on which, in the opinion of bond counsel or other
counsel to the issuer of such securities, is exempt from federal income tax.
Under normal market conditions, up to 100% but not less than 80%, of the Fund's
assets will be invested in municipal securities. The foregoing is a fundamental
policy of the Fund and cannot be changed without approval of the shareholders of
the Fund.
 
  The two principal classifications of municipal securities are "general
obligation" and "revenue" securities. "General obligation" securities are
secured by the issuer's pledge of its faith, credit and taxing power for the
payment of principal and interest. "Revenue" securities are usually payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a
 
                                       13
<PAGE>   69
 
special excise tax or other specific revenue source. Industrial development
bonds are usually revenue securities, the credit quality of which is normally
directly related to the credit standing of the industrial user involved.
 
  Within these principal classifications of municipal securities there are a
variety of categories of municipal securities, including fixed and variable rate
securities, municipal bonds, municipal notes, municipal leases, custodial
receipts, participation certificates and derivative municipal securities the
terms of which include elements of, or are similar in effect to, certain
Strategic Transactions (as defined below) in which the Fund may engage. Variable
rate securities bear rates of interest that are adjusted periodically according
to formulae intended to reflect market rates of interest and include securities
whose rates vary inversely with changes in market rates of interest. The Fund
will not invest more than 15% of its total assets in derivative municipal
securities such as inverse floaters, whose rates vary inversely with changes in
market rates of interest or range floaters or capped floaters whose rates are
subject to periodic or lifetime caps. Such securities may also pay a rate of
interest determined by applying a multiple to the variable rate. The extent of
increases and decreases in the value of securities whose rates vary inversely
with market rates of interest generally will be larger than comparable changes
in the value of such municipal securities generally will fluctuate in response
to changes in market rates of interest to a greater extent than the value of an
equal principal amount of a fixed rate municipal security having similar credit
quality, redemption provisions and maturity. Municipal notes include tax,
revenue and bond anticipation notes of short maturity, generally less than three
years, which are issued to obtain temporary funds for various public purposes.
Municipal leases are obligations issued by state and local governments or
authorities to finance the acquisition of equipment and facilities. Certain
municipal lease obligations may include "non-appropriation" clauses which
provide that the municipality has no obligation to make lease or installment
purchase payments in future years unless money is appropriated for such purpose
on a yearly basis. Custodial receipts are underwritten by securities dealers or
banks and evidence ownership of future interest payments, principal payments or
both on certain municipal securities. Participation certificates are obligations
issued by state or local governments or authorities to finance the acquisition
of equipment and facilities. They may represent participations in a lease, an
installment purchase contract, or a conditional sales contract. Some municipal
securities may not be backed by the faith, credit and taxing power of the
issuer. Certain of the municipal securities in which the Fund may invest
represent relatively recent innovations in the municipal securities markets.
While markets for such recent innovations progress through stages of
development, such markets may be less developed than more fully developed
markets for municipal securities. A more detailed description of the types of
municipal securities in which the Fund may invest is included in the Statement
of Additional Information.
 
  The net asset value of the Fund will change with changes in the value of its
portfolio securities. Because the Fund will invest primarily in fixed income
municipal securities, the net asset value of the Fund can be expected to change
as general
 
                                       14
<PAGE>   70
 
levels of interest rates fluctuate. When interest rates decline, the value of a
portfolio invested in fixed income securities generally can be expected to rise.
Conversely, when interest rates rise, the value of a portfolio invested in fixed
income securities generally can be expected to decline. Volatility may be
greater during periods of general economic uncertainty.
 
  From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
municipal securities. If such a proposal were enacted, the ability of the Fund
to pay tax exempt interest dividends might be adversely affected.
 
  LOWER GRADE MUNICIPAL SECURITIES. The Fund may invest up to 20% of its total
assets in lower grade tax-exempt municipal securities or in unrated municipal
securities considered by the Adviser to be of comparable quality. Lower grade
municipal securities are rated between BB and B- by S&P or between Ba and B3 by
Moody's, in each case inclusive of such rating categories. Higher yields are
generally available from municipal securities of such grade. With respect to
such 20% of the Fund's total assets, the Fund has not established any limit on
the percentage of its portfolio which may be invested in securities in any one
rating category.
 
  Investors should carefully consider the risks of owning shares of an
investment company which invests in lower grade municipal securities before
making an investment in the Fund. The higher yield on certain securities held by
the Fund reflects a greater possibility that the financial condition of the
issuer, or adverse changes in general economic conditions, or both, may impair
the ability of the issuer to make payments of income and principal. See "Special
Considerations Regarding the Fund."
 
  The Adviser seeks to minimize the risks involved in investing in lower grade
municipal securities through diversification and careful investment analysis. To
the extent that there is no established retail market for some of the lower
grade municipal securities in which the Fund may invest, trading in such
securities may be relatively inactive. The Adviser is responsible for
determining the net asset value of the Fund, subject to the supervision of the
Board of Trustees of the Trust. During periods of reduced market liquidity and
in the absence of readily available market quotations for lower grade municipal
securities held in the Fund's portfolio, the ability of the Adviser to value the
Fund's securities becomes more difficult and the Adviser's use of judgment may
play a greater role in the valuation of the Fund's securities due to the reduced
availability of reliable objective data. The effects of adverse publicity and
investor perceptions may be more pronounced for securities for which no
established retail market exists as compared with the effects on securities for
which such a market does exist. Further, the Fund may have more difficulty
selling such securities in a timely manner and at their stated value than would
be the case for securities for which an established retail market does exist.
See "Special Considerations Regarding the Fund."
 
                                       15
<PAGE>   71
 
  SELECTION OF INVESTMENTS. The Adviser will buy and sell securities for the
Fund's portfolio with a view to seeking a high level of current income exempt
from federal income tax and will select securities which the Adviser believes
entail reasonable credit risk considered in relation to the investment policies
of the Fund. As a result, the Fund will not necessarily invest in the highest
yielding tax-exempt municipal securities permitted by the investment policies if
the Adviser determines that market risks or credit risks associated with such
investments would subject the Fund's portfolio to excessive risk. The potential
for realization of capital gains resulting from possible changes in interest
rates will not be a major consideration. There is no limitation as to the
maturity of municipal securities in which the Fund may invest. The Adviser may
adjust the average maturity of the Fund's portfolio from time to time, depending
on its assessment of the relative yields available on securities of different
maturities and its expectations of future changes in interest rates. Other than
for tax purposes, frequency of portfolio turnover will generally not be a
limiting factor if the Fund considers it advantageous to purchase or sell
securities. The Fund may have annual portfolio turnover rates in excess of 100%.
A high rate of portfolio turnover involves correspondingly greater brokerage
commission expenses or dealer costs than a lower rate, which expenses and costs
must be borne by the Fund and its shareholders. High portfolio turnover may also
result in the realization of substantial net short-term capital gains and any
distributions resulting from such gains will be taxable. See "Tax Status" in
this Prospectus and "Investment Policies and Restrictions" in the Statement of
Additional Information.
 
  DEFENSIVE STRATEGIES. At times conditions in the markets for tax-exempt
municipal securities may, in the Adviser's judgment, make pursuing the Fund's
basic investment strategy inconsistent with the best interests of its
shareholders. At such times, the Adviser may use alternative strategies
primarily designed to reduce fluctuations in the value of the Fund's assets. In
implementing these "defensive" strategies, the Fund may invest to a substantial
degree in high-quality, short-term municipal obligations. If these high-quality,
short-term municipal obligations are not available or, in the Adviser's
judgment, do not afford sufficient protection against adverse market conditions,
the Fund may invest in taxable obligations. Such taxable obligations may
include: obligations of the U.S. Government, its agencies or instrumentalities;
other debt securities rated within the four highest grades by either S&P or
Moody's; commercial paper rated in the highest grade by either rating service;
certificates of deposit and bankers' acceptances; repurchase agreements with
respect to any of the foregoing investments; or any other fixed-income
securities that the Adviser considers consistent with such strategy.
 
- ------------------------------------------------------------------------------
INVESTMENT PRACTICES
- ------------------------------------------------------------------------------
 
  In connection with the investment policies described above, the Fund also may
engage in strategic transactions and purchase and sell securities on a "when
issued" and "delayed delivery" basis. These investments entail risks. Strategic
transactions
 
                                       16
<PAGE>   72
 
generally will not be treated as investments in tax-exempt municipal securities
for purposes of the Fund's 80% investment policy with respect thereto.
 
  STRATEGIC TRANSACTIONS. The Fund may purchase and sell derivative instruments
such as exchange-listed and over-the-counter put and call options on securities,
financial futures, fixed-income indices and other financial instruments,
purchase and sell financial futures contracts and enter into various interest
rate transactions such as swaps, caps, floors or collars. Collectively, all of
the above are referred to as "Strategic Transactions." Strategic Transactions
may be used to attempt to protect against possible changes in the market value
of securities held in or to be purchased for the Fund's portfolio resulting from
securities markets, to protect the Fund's unrealized gains in the value of its
portfolio securities, to facilitate the sale of such securities for investment
purposes, to manage the effective maturity or duration of the Fund's portfolio,
or to establish a position in the derivatives markets as a temporary substitute
for purchasing or selling particular securities. Any or all of these investment
techniques may be used at any time and there is no particular strategy that
dictates the use of one technique rather than another, as use of any Strategic
Transaction is a function of numerous variables including market conditions. The
ability of the Fund to utilize these Strategic Transactions successfully will
depend on the Adviser's ability to predict pertinent market movements, which
cannot be assured. The Fund will comply with applicable regulatory requirements
when implementing these strategies, techniques and instruments. Strategic
Transactions involving financial futures and options thereon will be purchased,
sold or entered into only for bona fide hedging, risk management or portfolio
management purposes and not for speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale of portfolio securities at inopportune times or for prices
other than at current market values, limit the amount of appreciation the Fund
can realize on its investments or cause the Fund to hold a security it might
otherwise sell. The use of options and futures transactions entails certain
other risks. In particular, the variable degree of correlation between price
movements of futures contracts and price movements in the related portfolio
position of the Fund creates the possibility that losses on the hedging
instrument may be greater than gains in the value of the Fund's position. In
addition, futures and options markets may not be liquid in all circumstances and
certain over-the-counter options may have no markets. As a result, in certain
markets, the Fund might not be able to close out a transaction without incurring
substantial losses, if at all. Although the contemplated use of these futures
contracts and options thereon should tend to minimize the risk of loss due to a
decline in the value of the hedged position, at the same time they tend to limit
any potential gain which might result from an increase in value of such
position. Finally, the daily variation margin requirements for futures contracts
would create a greater ongoing
 
                                       17
<PAGE>   73
 
potential financial risk than would purchases of options, where the exposure is
limited to the cost of the initial premium. Losses resulting from the use of
Strategic Transactions would reduce net asset value, and possibly income, and
such losses can be greater than if the Strategic Transactions had not been
utilized. The Strategic Transactions that the Fund may use and some of their
risks are described more fully in the Fund's Statement of Additional
Information.
 
  Income earned or deemed to be earned, if any, by the Fund from its Strategic
Transactions will generally be taxable income of the Fund. See "Tax Status."
 
  "WHEN ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS. The Fund may also purchase
and sell municipal securities on a "when issued" and "delayed delivery" basis.
No income accrues to the Fund on municipal securities in connection with such
purchase transactions prior to the date the Fund actually takes delivery of such
securities. These transactions are subject to market fluctuation; the value of
the municipal securities at delivery may be more or less than their purchase
price, and yields generally available on municipal securities when delivery
occurs may be higher or lower than yields on the municipal securities obtained
pursuant to such transactions. Because the Fund relies on the buyer or seller,
as the case may be, to consummate the transaction, failure by the other party to
complete the transaction may result in the Fund missing the opportunity of
obtaining a price or yield considered to be advantageous. When the Fund is the
buyer in such a transaction, however, it will maintain, in a segregated account
with its custodian, cash or high-grade municipal portfolio securities having an
aggregate value equal to the amount of such purchase commitments until payment
is made. The Fund will make commitments to purchase municipal securities on such
basis only with the intention of actually acquiring these securities, but the
Fund may sell such securities prior to the settlement date if such sale is
considered to be advisable. To the extent the Fund engages in "when issued" and
"delayed delivery" transactions, it will do so for the purpose of acquiring
securities for the Fund's portfolio consistent with the Fund's investment
objective and policies and not for the purposes of investment leverage. No
specific limitation exists as to the percentage of the Fund's assets which may
be used to acquire securities on a "when issued" or "delayed delivery" basis.
 
  OTHER PRACTICES. The Fund has no restrictions on the maturity of municipal
bonds in which it may invest. The Fund will seek to invest in municipal bonds of
such maturities that, in the judgment of the Fund and the Adviser, will provide
a high level of current income consistent with liquidity requirements and market
conditions.
 
  The Fund may borrow amounts up to 5% of its net assets in order to pay for
redemptions when liquidation of portfolio securities is considered
disadvantageous or inconvenient and may pledge up to 10% of its net assets to
secure such borrowings.
 
                                       18
<PAGE>   74
 
  The Fund generally will not invest more than 25% of its total assets in any
industry, nor will the Fund generally invest more than 5% of its assets in the
securities of any single issuer. Governmental issuers of municipal securities
are not considered part of any "industry." However, municipal securities backed
only by the assets and revenues of nongovernmental users may for this purpose be
deemed to be issued by such nongovernmental users, and the 25% limitation would
apply to such obligations. It is nonetheless possible that the Fund may invest
more than 25% of its assets in a broader segment of the municipal securities
market, such as revenue obligations of hospitals and other health care
facilities, housing agency revenue obligations, or airport revenue obligations
if the Adviser determines that the yields available from obligations in a
particular segment of the market justified the additional risks associated with
a large investment in such segment. Although such obligations could be supported
by the credit of governmental users, or by the credit of nongovernmental users
engaged in a number of industries, economic, business, political and other
developments generally affecting the revenues of such users (for example,
proposed legislation or pending court decisions affecting the financing of such
projects and market factors affecting the demand for their services or products)
may have a general adverse effect on all municipal securities in such a market
segment. The Fund reserves the right to invest more than 25% of its assets in
industrial development bonds or in issuers located in the same state, although
it has no present intention to invest more than 25% of its assets in issuers
located in the same state. If the Fund were to invest more than 25% of its
assets in issuers located in the same state, it would be more susceptible to
adverse economic, business, or regulatory conditions in that state.
 
  PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION. The Adviser is responsible
for decisions to buy and sell securities for the Fund, the selection of brokers
and dealers to effect the transactions and the negotiation of prices and any
brokerage commissions. The securities in which the Fund invests are traded
principally in the over-the-counter market. In the over-the-counter market,
securities are generally traded on a net basis with dealers acting as principal
for their own accounts without a stated commission, although the price of the
security usually includes a mark-up to the dealer. Securities purchased in
underwritten offerings generally include, in the price, a fixed amount of
compensation for the managers, underwriters and dealers. The Fund may also
purchase certain money market instruments directly from an issuer, in which case
no commissions or discounts are paid. Purchases and sales of bonds on a stock
exchange are effected through brokers who charge a commission for their
services.
 
  The Adviser is responsible for effecting securities transactions of the Fund
and will do so in a manner deemed fair and reasonable to shareholders of the
Fund and not according to any formula. The Adviser's primary considerations in
selecting the manner of executing securities transactions for the Fund will be
prompt execution of orders, the size and breadth of the market for the security,
the reliability, integrity and financial condition and execution capability of
the firm, the size of and difficulty in executing the order, and the best net
price. There are many instances
 
                                       19
<PAGE>   75
 
when, in the judgment of the Adviser, more than one firm can offer comparable
execution services. In selecting among such firms, consideration is given to
those firms which supply research and other services in addition to execution
services. However, it is not the policy of the Adviser, absent special
circumstances, to pay higher commissions to a firm because it has supplied such
services.
 
  In effecting purchases and sales of the Fund's portfolio securities, the
Adviser and the Fund may place orders with and pay brokerage commissions to
brokers, including brokers which may be affiliated with the Fund, the Adviser
and the Distributor or dealers participating in the offering of the Fund's
shares. In addition, in selecting among firms to handle a particular
transaction, the Adviser and the Fund may take into account whether the firm has
sold or is selling shares of the Fund. See "Portfolio Transactions and Brokerage
Allocation" in the Statement of Additional Information for more information.
 
- ------------------------------------------------------------------------------
SPECIAL CONSIDERATIONS REGARDING THE FUND
- ------------------------------------------------------------------------------
 
  In normal circumstances, the Fund may invest up to 20% of its total assets in
lower grade tax-exempt municipal securities or in unrated municipal securities
considered by the Adviser to be of comparable quality. Lower grade municipal
securities are rated between BB and B- by S&P or between Ba and B3 by Moody's,
in each case inclusive of such rating categories. Investment in lower grade
municipal securities involves special risks as compared with investment in
higher grade municipal securities. The market for lower grade municipal
securities is considered to be less liquid than the market for investment grade
municipal securities which may adversely affect the ability of the Fund to
dispose of such securities in a timely manner at a price which reflects the
value of such security in the Adviser's judgement. The market price for less
liquid securities tends to be more volatile than the market price for more
liquid securities. Illiquid securities and the absence of readily available
market quotations with respect thereto may make the Adviser's valuation of such
securities more difficult, and the Adviser's judgment may play a greater role in
the valuation of the Fund's securities. Lower grade municipal securities
generally involve greater credit risk than higher grade municipal securities and
are more sensitive to adverse economic changes, significant increases in
interest rates and individual issuer developments. Because issuers of lower
grade municipal securities frequently choose not to seek a rating of their
municipal securities, the Fund will rely more heavily on the Adviser's ability
to determine the relative investment quality of such securities than if the Fund
invested exclusively in higher grade municipal securities. The Fund may, if
deemed appropriate by the Adviser, retain a security whose rating has been
downgraded below B- by S&P or below B3 by Moody's, or whose rating has been
withdrawn. More detailed information concerning the risks associated with
instruments in lower grade municipal securities is included in the Fund's
Statement of Additional Information.

  The Fund may invest a substantial portion of its assets in municipal
securities that pay interest that is subject to the federal alternative minimum
tax. The Fund may not be a suitable investment for investors who are already
subject to the federal alternative minimum tax or who would become subject to
the federal alternative minimum tax as a result of an investment in the Fund.
 
  The table below sets forth the percentages of the Fund's assets invested
during the fiscal year ended December 31, 1994 in the various Moody's and S&P
rating categories and in unrated securities determined by the Adviser to be of
comparable quality. The percentages are based on the dollar-weighted average of
credit ratings of all municipal securities held by the Fund during the 1994
fiscal year, computed on a monthly basis.

Adviser, is primarily responsible for the day-to-day management of the Fund's
portfolio. Mr. Johnson has been employed by the Adviser for the last five years.
- ------------------------------------------------------------------------------
ALTERNATIVE SALES ARRANGEMENTS
- ------------------------------------------------------------------------------
 
  The Alternative Sales Arrangements permit an investor to choose the method of
purchasing shares that is more beneficial to the investor, taking into account
the amount of the purchase, the length of time the investor expects to hold the
shares, whether the investor wishes to receive dividends in cash or to reinvest
them in additional shares of the Fund, and other circumstances. Investors should
consider such factors together with the amount of sales charges and accumulated
distribution fees with respect to each class of shares that may be incurred over
the anticipated duration of their investment in the Fund.
 
  The Fund offers three classes of shares, designated Class A Shares, Class B
Shares and Class C Shares. Shares of each class are offered at a price equal to
their net asset value per share plus a sales charge which, at the election of
the purchaser, may be imposed (a) at the time of purchase ("Class A Shares") or
(b) on a contingent deferred basis (Class A Share accounts over $1 million,
"Class B Shares" and "Class C Shares"). Class A Share accounts over $1 million
or otherwise subject to a contingent deferred sales charge ("CDSC"), Class B
Shares and Class C Shares sometimes are referred to herein collectively as
"Contingent Deferred Sales Charge Shares" or "CDSC Shares."
 
  The minimum initial investment with respect to each class of shares is $500.
The minimum subsequent investment with respect to each class of shares is $25.
It is presently the policy of the Distributor, not to accept any order for Class
B Shares or Class C Shares in an amount of $1 million or more because it
ordinarily will be more advantageous for an investor making such an investment
to purchase Class A Shares.
 
  An investor should carefully consider the sales charges applicable to each
class of shares and the estimated period of their investment to determine which
class of shares is more beneficial for the investor to purchase. For example,
investors who would qualify for a significant purchase price discount from the
maximum sales charge on Class A Shares may determine that payment of such a
reduced front-end sales charge is superior to electing to purchase Class B
Shares or Class C Shares, each with no front-end sales charge but subject to a
CDSC and a higher aggregate distribution and service fee. However, because
initial sales charges are deducted at the time of purchase of Class A Share
accounts under $1 million, a purchaser of
 
                                       23
<PAGE>   79
 
such Class A Shares would not have all of his or her funds invested initially
and, therefore, would initially own fewer shares than if Class B Shares or Class
C Shares had been purchased. On the other hand, an investor whose purchase would
not qualify for price discounts applicable to Class A Shares and intends to
remain invested until after the expiration of the applicable CDSC may wish to
defer the sales charge and have all his or her funds initially invested in Class
B Shares or Class C Shares. If such an investor anticipates that he or she will
redeem such shares prior to the expiration of the CDSC period applicable to
Class B Shares, the investor may wish to acquire Class C Shares. Investors must
weigh the benefits of deferring the sales charge and having all of their funds
invested against the higher aggregate distribution and service fee applicable to
Class B Shares and Class C Shares (discussed below). Investors who intend to
hold their shares for a significantly long time may not wish to continue to bear
the ongoing distribution and service expenses of Class C Shares which in the
aggregate, eventually would exceed the aggregate amount of initial sales charge
and distribution and service expenses applicable to Class A Shares, irrespective
of the fact that a CDSC would eventually not apply to a redemption of such Class
C Shares.
 
  Each class of shares represents an interest in the same portfolio of
investments of the Fund and has the same rights, except each class of shares (i)
bears those distribution fees, service fees and administrative expenses
applicable to the respective class of shares as a result of its sales
arrangements, (ii) has exclusive voting rights with respect to those provisions
of the Fund's Rule 12b-1 distribution plan which relate only to such class and
(iii) has a different exchange privilege. Only the Class B Shares are subject to
a conversion feature (discussed below). Generally, a class of shares subject to
a higher ongoing distribution fee, service fee or, where applicable, the
conversion feature will have a higher expense ratio and pay lower dividends than
a class of shares subject to a lower ongoing distribution fee, service fee or
not subject to the conversion feature. The per share net asset values of the
different classes of shares are expected to be substantially the same; from time
to time, however, the per share net asset values of the classes may differ. The
net asset value per share of each class of shares of the Fund will be determined
as described in this Prospectus under "Purchase of Shares -- Net Asset Value."
 
  The administrative expenses that may be allocated to a specific class of
shares may consist of (i) transfer agency expenses attributable to a specific
class of shares, which expenses typically will be higher with respect to classes
of shares subject to the conversion feature; (ii) printing and postage expenses
related to preparing and distributing materials such as shareholder reports,
prospectuses and proxy statements to current shareholders of a specific class;
(iii) Securities and Exchange Commission (the "SEC") registration fees incurred
by a class of shares; (iv) the expense of administrative personnel and services
as required to support the shareholders of a specific class; (v) Trustees' fees
or expense incurred as a result of issues relating to one class of shares; (vi)
accounting expenses relating solely to one class of shares; and (vii) any other
incremental expenses subsequently identified that should be properly allocated
to one or more classes of shares that shall be
 
                                       24
<PAGE>   80
 
approved by the SEC pursuant to an amended exemptive order. All such expenses
incurred by a class will be borne on a pro rata basis by the outstanding shares
of such class. All allocations of administrative expenses to a particular class
of shares will be limited to the extent necessary to preserve the Fund's
qualification as a regulated investment company under the Internal Revenue Code
of 1986, as amended (the "Code").
 
- ------------------------------------------------------------------------------
PURCHASE OF SHARES
- ------------------------------------------------------------------------------
 
  The Fund offers shares for sale to the public on a continuous basis through
Van Kampen American Capital Distributors, Inc. (the "Distributor"), as principal
underwriter, which is located at One Parkview Plaza, Oakbrook Terrace, Illinois
60181. Shares are also offered through members of the National Association of
Securities Dealers, Inc. ("NASD") acting as securities dealers ("dealers") and
through NASD members acting as brokers for investors ("brokers") or eligible
non-NASD members acting as agents for investors ("financial intermediaries").
The Fund reserves the right to suspend or terminate the continuous public
offering of its shares at any time and without prior notice.
 
  The Fund's shares are offered at the net asset value per share next computed
after an investor places an order to purchase directly with the investor's
broker, dealer or financial intermediary or directly with the Distributor plus
any applicable sales charge. Sales personnel or brokers, dealers and financial
intermediaries distributing the Fund's shares may receive different compensation
for selling different classes of shares. It is the responsibility of the
investor's broker, dealer or financial intermediary to transmit the order to the
Distributor. Because the Fund generally will determine net asset value once each
business day as of the close of business, purchase orders placed through an
investor's broker, dealer or financial intermediary must be transmitted to the
Distributor by such broker, dealer or financial intermediary prior to such time
in order for the investor's order to be fulfilled on the basis of the net asset
value to be determined that day. Any change in the purchase price due to the
failure of the Distributor to receive a purchase order prior to such time must
be settled between the investor and the broker, dealer or financial intermediary
submitting the order.
 
  The Distributor may from time to time implement programs under which a broker,
dealer or financial intermediary's sales force may be eligible to win nominal
awards for certain sales efforts or under which the Distributor will reallow to
any broker, dealer or financial intermediary that sponsors sales contests or
recognition programs conforming to criteria established by the Distributor, or
participates in sales programs sponsored by the Distributor, an amount not
exceeding the total applicable sales charges on the sales generated by the
broker, dealer or financial intermediary at the public offering price during
such programs. Other programs provide, among other things and subject to certain
conditions, for certain favorable distribution arrangements for shares of the
Fund. Also, the Distributor in its discretion may from time to time, pursuant to
objective criteria established by it,
 
                                       25
<PAGE>   81
 
pay fees to, and sponsor business seminars for, qualifying brokers, dealers or
financial intermediaries for certain services or activities which are primarily
intended to result in sales of shares of the Fund. Fees may include payment for
travel expenses, including lodging, incurred in connection with trips taken by
invited registered representatives and members of their families to locations
within or outside of the United States for meetings or seminars of a business
nature. Such fees paid for such services and activities with respect to the Fund
will not exceed in the aggregate 1.25% of the average total daily net assets of
the Fund on an annual basis. In addition, the Distributor may provide additional
compensation to Edward D. Jones & Co. ("Edward D. Jones") or an affiliate
thereof based on a combination of its sales of shares and increases in assets
under management. Such payments to brokers, dealers and financial intermediaries
for sales contests, other sales programs and seminars are made by the
Distributor out of its own assets and not out of the assets of the Fund. These
programs will not change the price an investor pays for shares or the amount
that the Fund will receive from such sale.
 
CLASS A SHARES
 
  The public offering price of Class A Shares is equal to the net asset value
per share plus an initial sales charge which is a variable percentage of the
offering price depending upon the amount of the sale. The table below shows
total sales charges and dealer concessions reallowed to dealers and agency
commissions paid to brokers with respect to sales of Class A Shares. The sales
charge is allocated between an investor's broker, dealer or financial
intermediary and the Distributor. As indicated previously, at the discretion of
the Distributor, the entire sales charge may be reallowed to such broker, dealer
or financial intermediary. The staff of the SEC has taken the position that
brokers, dealers or financial intermediaries who receive 90% or more of the
sales charge may be deemed to be "underwriters" as that term is defined in the
Securities Act of 1933.

* No sales charge is payable at the time of purchase on investments of $1
  million or more, although for such investments the Fund imposes a contingent
  deferred sales charge of 1.00% on redemptions made within one year of the
  purchase. A commission will be paid to dealers who initiate and are
  responsible for purchases of $1 million or more as follows: 1.00% on sales to
  $2 million, plus 0.80% on the next million, plus 0.20% on the next $2 million
  and 0.08% on the excess over $5 million. See "Purchase of Shares -- Deferred
  Sales Charge Alternatives" for additional information with respect to
  contingent deferred sales charges.

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.
 
  As used herein, "any person" eligible for a reduced sales charge includes an
individual, their spouse and minor children (and any trust or custodial accounts
for their benefit) 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 is 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 ("Money Market Fund"), Van Kampen American Capital Tax Free
Money Fund ("Tax Free Money Fund"), Van Kampen American Capital Reserve Fund
("Reserve Fund") 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 at any one time in Class
A Shares of the Fund alone, or in combination with other 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 Class A
Shares of the Fund with other shares of the Fund and shares of Participating
Funds plus the current offering price of all shares of the Fund and other
Participating Funds which have been previously purchased and are still owned.
 
  LETTER OF INTENT. A Letter of Intent provides an opportunity for an investor
to obtain a reduced sales charge by aggregating the amount being invested over a
13-month period to determine the sales charge as outlined in the preceding
table. The size of investment shown in the preceding table includes the amount
of intended purchases of Class A Shares of the Fund with other shares of the
Fund and shares of the Participating Funds plus the value of all shares of the
Fund and other Participating Funds previously purchased during such 13-month
period and still owned. An investor may elect to compute the 13-month period
starting up to 90 days before the date of execution of a Letter of Intent. Each
investment made during the period receives the reduced sales charge applicable
to the total amount of
 
                                       27
<PAGE>   83
 
the investment goal. If trades not initially made under a Letter of Intent
subsequently qualify for a lower sales charge through the 90-day back-dating
provision, an adjustment will be made at the expiration of the Letter of Intent
to give effect to the lower charge. If the goal is not achieved within the
13-month period, the investor must pay the difference between the charges
applicable to the purchases made and the charges previously paid. When an
investor signs a Letter of Intent, shares equal to at least 5% of the total
purchase amount of the level selected will be restricted from sale or redemption
by the investor until the Letter of Intent is satisfied or any additional sales
charges have been paid; if the Letter of Intent is not satisfied by the investor
and any additional sales charges are not paid, sufficient restricted shares will
be redeemed by the Fund to pay such charges. Additional information is contained
in the application accompanying this Prospectus.
 
OTHER PURCHASE PROGRAMS
 
  Purchasers of Class A Shares may be entitled to reduced initial sales charges
in connection with unit 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 TRUST REINVESTMENT PROGRAMS. The Fund permits unitholders of unit
investment trusts to reinvest distributions from such trusts in Class A Shares
of the Fund with no minimum initial or subsequent investment requirement, and
with a lower sales charge if the administrator of an investor's unit investment
trust program meets certain uniform criteria relating to cost savings by the
Fund and the Distributor. The total sales charge for all investments made from
unit trust distributions will be 1.00% of the offering price (1.01% of net asset
value). Of this amount, the Distributor will pay to the broker, dealer or
financial intermediary, if any, through which such participation in the
qualifying program was initiated 0.50% of the offering price as a dealer
concession or agency commission. Persons desiring more information with respect
to this program, including the applicable terms and conditions thereof, should
contact their broker, dealer or financial intermediary or the Distributor.
 
  The administrator of such a unit investment trust must have an agreement with
the Distributor pursuant to which the administrator will (1) submit a single
bulk order and make payment with a single remittance for all investments in the
Fund during each distribution period by all investors who choose to invest in
the Fund through the program and (2) provide the Fund's transfer agent with
appropriate backup data for each participating investor in a computerized format
fully compatible with the transfer agent's processing system.
 
  As further requirements for obtaining these special benefits, the Fund also
requires that all dividends and other distributions by the Fund be reinvested in
additional shares without any systematic withdrawal program. There will be no
minimum for reinvestments from unit investment trusts. The Fund will send
 
                                       28
<PAGE>   84
 
account activity statements to such participants on a monthly basis only, even
if their investments are made more frequently.
 
  NAV PURCHASE OPTIONS. Class A Shares of the Fund may be purchased at net asset
value, upon written assurance that the purchase is made for investment purposes
and that the shares will not be resold except through redemption by the Fund,
by:
 
  (1) Current or retired Trustees/Directors of funds advised by the Adviser, Van
      Kampen American Capital Asset Management, Inc. or John Govett & Co.
      Limited and such persons' families and their beneficial accounts.
 
  (2) Current or retired directors, officers and employees of VK/AC Holding,
      Inc. and any of its subsidiaries, Clayton, Dubilier & Rice, Inc.,

      beneficial accounts.
 
  (3) Directors, officers, employees and registered representatives of financial
      institutions that have a selling group agreement with the Distributor and
      their spouses and minor children when purchasing for any accounts they
      beneficially own, or, in the case of any such financial institution, when
      purchasing for retirement plans for such institution's employees.
 
  (4) Registered investment advisers, trust companies and bank trust departments
      investing on their own behalf or on behalf of their clients provided that
      the aggregate amount invested in Class A Shares of the Fund alone, or in
      any combination of shares of the Fund and shares of other Participating
      Funds as described herein under "Purchase of Shares -- Class A Shares --
      Quantity Discounts," during the 13-month period commencing with the first
      investment pursuant hereto equals at least $1 million. The Distributor may
      pay brokers, dealers or financial intermediaries through which purchases
      are made an amount up to 0.50% of the amount invested, over a twelve-month
      period following such transaction.
 
  (5) Trustees and other fiduciaries purchasing shares for retirement plans of
      organizations with retirement plan assets of $10 million or more. The
      Distributor may pay commissions of up to 1.00% for such purchases.
 
  (6) Accounts as to which a broker, dealer or financial intermediary charges an
      account management fee ("wrap accounts"), provided the broker, dealer or
      financial intermediary has a separate agreement with the Distributor.
 
  (7) Investors purchasing shares of the Fund with redemption proceeds from
      other mutual fund complexes on which the investor has paid a front-end
      sales charge or was subject to a deferred sales charge, whether or not
      paid, if such redemption has occurred no more than 30 days prior to such
      purchase.

                                       29
<PAGE>   85
 
      made available through Van Kampen American Capital Trust Company with at
      least 50 eligible employees or investing at least $250,000 in the
      Participating Funds, Money Market Fund, Tax Free Money Fund or Reserve
      Fund. For such investments the Fund imposes a contingent deferred sales
      charge of 1.00% in the event of redemptions within one year of the
      purchase other than redemptions required to make payments to participants
      under the terms of the plan. The contingent deferred sales charge incurred
      upon certain redemptions is paid to the Distributor in reimbursement for
      distribution-related expenses. A commission will be paid to dealers who
      initiate and are responsible for such purchases as follows: 1.00% on sales
      to $5 million, plus 0.50% on the next $5 million, plus 0.25% on the excess
      over $10 million.
 
The term "families" includes a person's spouse, minor children and
grandchildren, parents, and a person's spouse's parents.
 
  Purchase orders made pursuant to clause (4) may be placed either through
authorized brokers, dealers or financial intermediaries as described above or
directly with the Fund's transfer agent, the investment adviser, trust company
or bank trust department, provided that the Fund's transfer agent receives
federal funds for the purchase by the close of business on the next business day
following acceptance of the order. An authorized broker, dealer or financial
intermediary may charge a transaction fee for placing an order to purchase
shares pursuant to this provision or for placing a redemption order with respect
to such shares. The Fund may terminate, or amend the terms of, offering shares
of the Fund at net asset value to such groups at any time.
 
DEFERRED SALES CHARGE ALTERNATIVES
 
  Investors choosing the deferred sales charge alternative may purchase Class A
Shares in an amount of $1 million or more, Class B Shares or Class C Shares. The
public offering price of a CDSC Share is equal to the net asset value per share
without the imposition of a sales charge at the time of purchase. CDSC Shares
are sold without an initial sales charge so that the Fund may invest the full
amount of the investor's purchase payment. The Distributor will compensate
brokers, dealers and financial intermediaries participating in the continuous
public offering of the CDSC Shares out of its own assets, and not out of assets
of the Fund, as a percentage rate of the dollar value of the CDSC Shares
purchased from the Fund by such brokers, dealers and financial intermediaries
which percentage rate will be equal to (i) with respect to Class A Shares, 1.00%
on sales to $2 million, plus 0.80% on the next million, plus 0.20% on the next
$2 million and 0.08% on the excess over $5 million; (ii) 4.00% with respect to
Class B Shares; and (iii) 1.00% with respect to Class C Shares. Such
compensation will not change the price an investor will pay for CDSC Shares or
the amount that the Fund will receive from such sale.
 
  CDSC Shares redeemed within a specified period of time generally will be
subject to a contingent deferred sales charge at the rates set forth below. The
 
                                       30
<PAGE>   86
 
amount of the contingent deferred sales charge will vary depending on (i) the
class of CDSC Shares to which such shares belong and (ii) the number of years
from the time of payment for the purchase of the CDSC Shares until the time of
their redemption. The charge will be assessed on an amount equal to the lesser
of the then current market value or the original purchase price of the CDSC
Shares being redeemed. Accordingly, no sales charge will be imposed on increases
in net asset value above the initial purchase price. In addition, no contingent
deferred sales charge will be assessed on CDSC Shares derived from reinvestment
of dividends or capital gains distributions. Solely for purposes of determining
the number of years from the time of any payment for the purchases of CDSC
Shares, all payments during a month will be aggregated and deemed to have been
made on the last day of the month.
 
  Proceeds from the contingent deferred sales charge applicable to a class of
CDSC Shares are paid to the Distributor and are used by the Distributor to
defray its expenses related to providing distribution related services to the
Fund in connection with the sale of shares of such class of CDSC Shares, such as
the payment of compensation to selected dealers and agents and for selling such
shares. The combination of the contingent deferred sales charge and the
distribution and service fees facilitates the ability of the Fund to sell such
CDSC Shares without a sales charge being deducted at the time of purchase.
 
  In determining whether a contingent deferred sales charge is applicable to a
redemption of CDSC Shares, it will be assumed that the redemption is made first
of any CDSC Shares acquired pursuant to reinvestment of dividends or
distributions, second of CDSC Shares that have been held for a sufficient period
of time such that the contingent deferred sales charge no longer is applicable
to such shares, third of Class A Shares in the shareholder's Fund account that
have converted from Class B Shares, if any, and fourth of CDSC Shares held
longest during the period of time that a contingent deferred sales charge is
applicable to such CDSC Shares. The charge will not be applied to dollar amounts
representing an increase in the net asset value since the time of purchase.
 
  To provide an example, assume an investor purchased 100 Class B Shares at $10
per share (at a cost of $1,000) and in the second year after purchase, the net
asset value per share is $12 and, during such time, the investor has acquired 10
additional Class B Shares upon dividend reinvestment. If at such time the
investor makes his first redemption of 50 shares (proceeds of $600), 10 shares
will not be subject to charge because of dividend reinvestment. With respect to
the remaining 40 shares, the charge is applied only to the original cost of $10
per share and not to the increase in net asset value of $2 per share. Therefore,
$400 of the $600 redemption proceeds will be charged at a rate of 3.75% (the
applicable rate in the second year after purchase).
 
  CLASS A SHARE PURCHASES OF $1 MILLION OR MORE. No sales charge is payable at
the time of purchase on investments in Class A Shares of $1 million or more,
although for such investments the Fund imposes a contingent deferred sales
charge of 1.00%
 
                                       31
<PAGE>   87
 
on redemptions made within one year of the purchase. A commission will be paid
to dealers who initiate and are responsible for purchases of $1 million or more
as follows: 1% on sales to $2 million, plus 0.80% on the next million, plus
0.20% on the next $2 million and 0.08% on the excess over $5 million.
 
  CLASS B SHARES. Class B Shares redeemed within six years of purchase generally
will be subject to a contingent deferred sales charge at the rates set forth
below, charged as a percentage of the dollar amount subject thereto:

</TABLE>
 
  The contingent deferred sales charge generally is waived on redemptions of
Class B Shares made pursuant to the Systematic Withdrawal Plan. See "Shareholder
Services -- Systematic Withdrawal Plan."
 
  Conversion Feature. Six years after the end of the month in which a
shareholder's order to purchase a Class B Share of the Fund was accepted, such
Class B Share automatically will convert to a Class A Share and will no longer
be subject to the higher aggregate distribution and service fees. The purpose of
the conversion feature is to relieve the holders of Class B Shares that have
been outstanding for a period of time sufficient for the Distributor to have
been compensated for distribution expenses related to the Class B Shares from
most of the burden of such distribution-related expenses. The Fund does not
expect to issue any stock certificates upon conversion.
 
  For purposes of conversion to Class A Shares, Class B Shares purchased through
the reinvestment of dividends and distributions paid in respect of Class B
Shares in a shareholder's account will be considered to be held in a separate
sub-account. Each time any Class B Shares in the shareholder's account (other
than those in the sub-account) convert to Class A Shares, an equal pro rata
portion of the Class B Shares in the sub-account also will convert to Class A
Shares. The holding period applicable to a Class B Share acquired through the
use of the exchange privilege (discussed below) shall be the holding period
applicable to a Class B Share of such Fund acquired other than through use of
the exchange privilege. For purposes of calculating the holding period
applicable to a Class B Share of the Fund prior to conversion, a Class B Share
of the Fund issued in connection with an exercise of the exchange privilege, or
a series of exchanges, shall be deemed to have been issued on
 
                                       32
<PAGE>   88
 
the date on which the investor's order to purchase the exchanged Class B Share
was accepted or, in the case of a series of exchanges, when the investor's order
to purchase the original Class B Share was accepted.
 
  The conversion of Class B Shares to Class A Shares is subject to the
continuing availability of an opinion of counsel to the effect that (i) the
assessment of the higher distribution services fee and transfer agency costs
with respect to Class B Shares does not result in the Fund's dividends or
distributions constituting "preferential dividends" under the Code and (ii) that
the conversion of Class B Shares does not constitute a taxable event under
federal income tax law. The conversion of Class B Shares to Class A Shares may
be suspended if such an opinion is no longer available. In that event, no
further conversions of Class B Shares would occur, and Class B Shares might
continue to be subject to the higher aggregate distribution and service fees for
an indefinite period.
 
  CLASS C SHARES. Class C Shares redeemed within the first twelve months of
purchase generally will be subject to a contingent deferred sales charge of
1.00% of the dollar amount subject thereto. Class C Shares redeemed thereafter
will not be subject to a contingent deferred sales charge. Class C Shares of the
Fund do not convert to Class A Shares.
 
  WAIVER OF CONTINGENT DEFERRED SALES CHARGE.  The contingent deferred sales
charge is waived on redemptions of Class B Shares and Class C Shares (i)
following the death or disability (as defined in the Code) of a shareholder,
(ii) in connection with 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 "Shareholder Services" and "Redemption of Shares" for further
discussion of the waiver provisions.
 
NET ASSET VALUE
 
  The net asset value per share of the Fund will be determined separately for
each class of shares. The net asset value per share of a given class of shares
of the Fund is determined by calculating the total value of the Fund's assets
attributable to such class of shares, deducting its total liabilities
attributable to such class of shares, and dividing the result by the number of
shares of such class outstanding. The net asset value for the Fund is computed
once daily as of 5:00 p.m. Eastern time Monday through Friday, except on
customary business holidays, or except on any day on which no purchase or
redemption orders are received, or there is not a sufficient degree of trading
in the Fund's portfolio securities such that the Fund's net asset value per
share might be materially affected. The Fund reserves the right to calculate the
net asset value and to adjust the public offering price based thereon
 
                                       33
<PAGE>   89
 
more frequently than once a day if deemed desirable. The net asset value per
share of the different classes of shares are expected to be substantially the
same; from time to time, however, the per share net asset value of the different
classes of shares may differ.
 
  Portfolio securities are valued by using market quotations, prices provided by
market makers or estimates of market values obtained from yield data relating to
instruments or securities with similar characteristics in accordance with
procedures established in good faith by the Board of Trustees of the Trust, of
which the Fund is a series. Securities with remaining maturities of 60 days or
less are valued at amortized cost when amortized cost is determined in good
faith by or under the direction of the Board of Trustees of the Trust to be
representative of the fair value at which it is expected such securities may be
resold. Any securities or other assets for which current market quotations are
not readily available are valued at their fair value as determined in good faith
under procedures established by and under the general supervision of the Board
of Trustees of the Trust.
 
- ------------------------------------------------------------------------------
SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------
 
  The Fund offers a number of shareholder services designed to facilitate
investment in its shares at little or no extra cost to the investor. Below is a
description of such services. Unless otherwise described below, each of these
services may be modified or terminated by the Fund at any time.
 
SHAREHOLDER SERVICES APPLICABLE TO ALL CLASSES
 
  INVESTMENT ACCOUNT. ACCESS Investor Services, Inc. ("ACCESS"), transfer agent
for the Fund and a wholly-owned subsidiary of Van Kampen American Capital,
performs bookkeeping, data processing and administration services related to the
maintenance of shareholder accounts. Each shareholder has an investment account
under which shares are held by ACCESS. Except as described herein, after each
share transaction in an account, the shareholder receives a statement showing
the activity in the account. Each shareholder will receive statements at least
quarterly from ACCESS showing any reinvestments of dividends and capital gains
distributions and any other activity in the account since the preceding
statement. Such shareholders also will receive separate confirmations for each
purchase or sale transaction other than reinvestment of dividends and capital
gains distributions and systematic purchases or redemptions. Additions to an
investment account may be made at any time by purchasing shares through
authorized brokers, dealers or financial intermediaries or by mailing a check
directly to ACCESS.
 
  SHARE CERTIFICATES. Generally, the Fund will not issue share certificates.
However, upon written or telephone request to the Fund, a share certificate will
be issued, representing shares (with the exception of fractional shares) of the
Fund. A shareholder will be required to surrender such certificates upon
redemption thereof.
 
                                       34
<PAGE>   90
 
In addition, if such certificates are lost the shareholder must write to Van
Kampen American Capital Funds, c/o ACCESS, P.O. Box 418256, Kansas City, MO
64141-9256, requesting an "affidavit of loss" and to obtain a Surety Bond in a
form acceptable to ACCESS. On the date the letter is received ACCESS will
calculate a fee for replacing the lost certificate equal to no more than 2.00%
of the net asset value of the issued shares and bill the party to whom the
replacement certificate was mailed.
 
  REINVESTMENT PLAN. A convenient way for investors to accumulate additional
shares is by accepting dividends and capital gains distributions in shares of
the Fund. Such shares are acquired at net asset value (without sales charge) on
the record date of such dividend or distribution. Unless the shareholder
instructs otherwise, the reinvestment plan is automatic. This instruction may be
made by telephone by calling (800) 421-5666 ((800) 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. For further information, see
"Distributions from the Fund."
 
  AUTOMATIC INVESTMENT PLAN. An automatic investment plan is available under
which a shareholder can authorize ACCESS to charge a bank account on a regular
basis to invest pre-determined amounts in the Fund. Additional information is
available from the Distributor or authorized brokers, dealers or financial
intermediaries.
 
  DIVIDEND DIVERSIFICATION. A shareholder may, upon written request or by
completing the appropriate section of the application form accompanied by this
Prospectus or by calling (800) 421-5666 ((800) 772-8889 for the hearing
impaired), elect to have all dividends and other distributions paid on a class
of shares of the Fund invested into shares of the same class of any other
Participating Fund, Money Market Fund, Tax Free Money Fund or Reserve Fund so
long as a pre-existing account for such class of shares exists for such
shareholder.
 
  If the qualified pre-existing account does not exist, the shareholder must
establish a new account subject to minimum investment and other requirements of
the fund into which distributions would be invested. Distributions are invested
into the selected fund at its net asset value as of the payable date of the
distribution only if shares of such selected fund have been registered for sale
in the investor's state.
 
  EXCHANGE PRIVILEGE. Shares of the Fund may be exchanged with shares of another
Participating Fund, the Money Market Fund, the Tax Free Money Fund or the
Reserve Fund, subject to certain limitations herein or in such other fund's
prospectus. Before effecting an exchange, shareholders in the Fund should obtain
and read a current prospectus of the fund into which the exchange is to be made.
SHAREHOLDERS MAY ONLY EXCHANGE INTO SUCH OTHER FUNDS AS ARE LEGALLY AVAILABLE
FOR SALE IN THEIR STATE.
 
                                       35
<PAGE>   91
 
  In general, shares of the Fund must have been registered in the shareholder's
name for at least 15 days prior to an exchange. Shares of the Fund registered in
a shareholder's name for less than 15 days may only be exchanged upon receipt of
prior approval of the Adviser; however, under normal circumstances, it is the
policy of the Adviser not to approve such requests. Upon 60 days after the date
of this prospectus, the Fund will increase the number of days shares must be
registered in a shareholder's name prior to an exchange to 30 days.
 
  Exchanges of Class A Shares of the Fund that have been charged a sales charge
lower than the sales charge applicable to the other fund will have the sales
charge differential imposed upon the exchange into such fund. Similarly,
exchanges of any Class A Shares of other funds that have been charged a sales
charge lower than the sales charge applicable to the Fund will have the sales
charge differential imposed upon exchange into the Fund. Shares of other funds
which have not previously been charged a sales charge (except for shares
purchased via the reinvestment option) will be charged the sales charge
differential applicable to Class A Shares of the Fund upon exchange into the
Fund.
 
  No sales charge is imposed upon the exchange of Class B Shares and Class C
Shares. Upon redemption of Class B Shares and Class C Shares from the Van Kampen
American Capital family of funds, Class B Shares and Class C Shares which have
been exchanged are subject to the contingent deferred sales charge imposed by
the initial Van Kampen American Capital fund purchased by the investor prior to
any exchanges. The holding period requirements for the contingent deferred sales
charge, and the conversion privilege for Class B Shares of the Fund, are
determined by the date of purchase into the initial Van Kampen American Capital
fund purchased by the investor prior to any exchanges.
 
  Exchanges of shares are sales and may result in a gain or loss for federal
income tax purposes. If the shares exchanged have been held for less than 91
days, the sales charge paid on such shares is not included in the tax basis of
the exchanged shares, but is carried over and included in the tax basis of the
shares acquired.
 
  A shareholder wishing to make an exchange may do so by sending a written
request to ACCESS or by contacting the telephone transaction line at (800)
421-5684 ((800) 772-8889 for the hearing impaired). A shareholder automatically
has telephone exchange privileges unless otherwise designated in the application
form accompanied by this Prospectus. The exchange will take place at the
relative net asset values of the shares next determined after receipt of such
request with adjustment for any additional sales charge. Any shares exchanged
begin earning dividends on the next business day after the exchange is affected.
Van Kampen American Capital and its subsidiaries, including ACCESS
(collectively, "VKAC"), and the Fund employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications, and providing written confirmation of instructions communicated
by telephone. If
 
                                       36
<PAGE>   92
 
reasonable procedures are employed, a shareholder agrees that neither VKAC nor
the Fund will be liable for following telephone instructions which it reasonably
believes to be genuine. VKAC and the Fund may be liable for any losses due to
unauthorized or fraudulent instructions if reasonable procedures are not
followed. If the exchanging shareholder does not have an account in the fund
whose shares are being acquired, a new account will be established with the same
registration, dividend and capital gains options (except dividend
diversification options) and broker, dealer or financial intermediary of record
as the account from which shares are exchanged, unless otherwise specified by
the shareholder. In order to establish a systematic withdrawal plan for the new
account or dividend diversification options for the new account, 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 restrict or terminate the exchange privilege at any time on 60 days' notice
to its shareholders of any termination or material amendment.
 
  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 taxable gain or loss will be
recognized. The plan holder may arrange for monthly, quarterly, semi-annual, or
annual checks in any amount not less than $25.
 
  Holders of Class B Shares and Class C Shares who establish a withdrawal plan
may redeem up to 12% annually of the shareholder's initial account balance
without incurring a contingent deferred sales charge. Initial account balance
means the amount of the shareholder's investment in the Fund at the time the
election to participate in the plan is made. See "Purchase of Shares -- Deferred
Sales Charge Alternatives -- Waiver of Contingent Deferred Sales Charge."
 
  Under the plan, sufficient shares of the Fund are redeemed to provide the
amount of the periodic withdrawal payment. Dividends and capital gains
distributions on shares held under the plan are reinvested in additional shares
at the next determined net asset value. If periodic withdrawals continuously
exceed reinvested dividends and capital gains distributions, the shareholder's
original investment will be correspondingly reduced and ultimately exhausted.
Withdrawals made concurrently with purchases of additional shares ordinarily
will be disadvantageous to the shareholder because of the duplication of sales
charges. The Fund reserves the right to amend or terminate the systematic
withdrawal program on thirty days' notice to its shareholders.

SHAREHOLDER SERVICES APPLICABLE TO CLASS A SHAREHOLDERS ONLY
 
  CHECK WRITING PRIVILEGE. Holders of Class A Shares of the Fund for which
certificates have not been issued and which are in a non-escrow status may
appoint ACCESS as agent by completing the Authorization for Redemption by Check
Form and the appropriate section of the application and returning the form and
the application to ACCESS. Once the form is properly completed, signed and
returned to the agent, a supply of checks drawn on State Street Bank and Trust
Company ("State Street Bank") will be sent to such shareholder. These checks may
be made payable by the holder of Class A Shares to the order of any person in
any amount of $100 or more.
 
  When a check is presented to State Street Bank for payment, full and
fractional Class A Shares required to cover the amount of the check are redeemed
from the shareholder's account by ACCESS at the next determined net asset value.
Check writing redemptions represent the sale of Class A Shares. Any gain or loss
realized on the sale of Class A Shares is a taxable event. See "Redemption of
Shares."
 
  Checks will not be honored for redemption of Class A Shares held less than 15
calendar days, unless such Class A Shares have been paid for by bank wire. Any
Class A Shares for which there are outstanding certificates may not be redeemed
by check. If the amount of the check is greater than the proceeds of all
uncertificated shares held in the shareholder's Class A Share account, the check
will be returned and the shareholder may be subject to additional charges.
Holders of Class A Shares may not liquidate the entire account by means of a
check. The check writing privilege may be terminated or suspended at any time by
the Fund or State Street Bank. Retirement plans and accounts that are subject to
backup withholding are not eligible for the privilege. A "stop payment" system
is not available on these checks.
 
  AUTOMATED CLEARING HOUSE ("ACH") DEPOSITS. Holders of Class A Shares can use
ACH to have redemption proceeds deposited electronically into their bank
accounts. Redemptions transferred to a bank account via the ACH plan are
available to be credited to the account on the second business day following
normal payment. In order to utilize this option, the shareholder's bank must be
a member of Automated Clearing House. In addition, the shareholder must fill out
the appropriate section of the account application. The shareholder must also
include a voided check or deposit slip from the bank account into which
redemptions are to be deposited together with the completed application. Once
ACCESS has received the application and the voided check or deposit slip, such
shareholder's designated bank account, following any redemption, will be
credited with the proceeds of such redemption. Once enrolled in the ACH plan, a
shareholder may terminate participation at any time by writing ACCESS.

- ------------------------------------------------------------------------------
REDEMPTION OF SHARES
- ------------------------------------------------------------------------------
 
  Shareholders may redeem for cash some or all of their shares without charge by
the Fund (other than, with respect to CDSC Shares, the applicable contingent
deferred sales charge) at any time by sending a written request in proper form
directly to ACCESS, P. O. Box 418256, Kansas City, Missouri 64141-9256, by
placing the redemption request through an authorized dealer or by calling the
Fund.
 
  WRITTEN REDEMPTION REQUESTS. In the case of redemption requests sent directly
to ACCESS, the redemption request should indicate the number of shares to be
redeemed, the class designation of such shares, the account number and be signed
exactly as the shares are registered. Signatures must conform exactly to the
account registration. If the proceeds of the redemption would exceed $50,000, or
if the proceeds are not to be paid to the record owner at the record address, or
if the record address has changed within the previous 30 days, signature(s) must
be guaranteed by one of the following: a bank or trust company; a broker-dealer;
a credit union; a national securities exchange, registered securities
association or clearing agency; a savings and loan association; or a federal
savings bank. If certificates are held for the shares being redeemed, such
certificates must be endorsed for transfer or accompanied by an endorsed stock
power and sent with the redemption request. In the event the redemption is
requested by a corporation, partnership, trust, fiduciary, executor or
administrator, and the name and title of the individual(s) authorizing such
redemption is not shown in the account registration, a copy of the corporate
resolution or other legal documentation appointing the authorized signer and
certified within the prior 60 days must accompany the redemption request. The
redemption price is the net asset value per share next determined after the
request is received by ACCESS in proper form. Payment for shares redeemed (less
any sales charge, if applicable) will ordinarily be made by check mailed within
three business days after acceptance by ACCESS of the request and any other
necessary documents in proper order. Such payments may be postponed or the right
of redemption suspended as provided by the rules of the SEC. If the shares to be
redeemed have been recently purchased by check, ACCESS may delay mailing a
redemption check until it confirms that the purchase check has cleared, usually
a period of up to 15 days. Any gain or loss realized on the redemption of shares
is a taxable event.
 
  DEALER REDEMPTION REQUESTS. Shareholders may sell shares through their
securities dealer, who will telephone the request to the Distributor. Orders
received from dealers must be at least $500 unless transmitted via the FUNDSERV
network. The redemption price for such shares is the net asset value next
calculated after an order is received by a dealer provided such order is
transmitted to the Distributor prior to the Distributor's close of business on
such day. It is the responsibility of dealers to transmit redemption requests
received by them to the Distributor so they will be received prior to such time.
Any change in the redemption price due to failure of the Distributor to receive
a sell order prior to such time must be settled between the
 
                                       39
<PAGE>   95
 
shareholder and dealer. Shareholders must submit a written redemption request in
proper form (as described above under "Written Redemption Requests") to the
dealer within three business days after calling the dealer with the sell order.
Payment for shares redeemed (less any sales charge, if applicable) will
ordinarily be made by check mailed within three business days to the dealer.
 
  TELEPHONE REDEMPTION REQUESTS. The Fund permits redemption of shares by
telephone and for redemption proceeds to be sent to the address of record for
the account or to the bank account of record as described below. To establish
such privilege, a shareholder must complete the appropriate section of the
application form accompanying this Prospectus or call the Fund at (800) 421-5666
((800) 772-8889 for the hearing impaired) to request that a copy of the
Telephone Redemption Authorization form be sent to them for completion. To
redeem shares, contact the telephone transaction line at (800) 421-5684. VKAC
and the Fund employ procedures considered by them to be reasonable to confirm
that instructions communicated by telephone are genuine. Such procedures include
requiring certain personal identification information prior to acting upon
telephone instructions, tape recording telephone communications, and providing
written confirmation of instructions communicated by telephone. If reasonable
procedures are employed, a shareholder agrees that neither VKAC nor the Fund
will be liable for following instructions which it reasonably believes to be
genuine. VKAC and the Fund may be liable for any losses due to unauthorized or
fraudulent instructions if reasonable procedures are not followed. Telephone
redemptions may not be available if the shareholder cannot reach ACCESS by
telephone, whether because all telephone lines are busy or for any other reason;
in such case, a shareholder would have to use the Fund's other redemption
procedures previously described. Requests received by ACCESS prior to 4:00 p.m.,
New York time, on a regular business day will be processed at the net asset
value per share determined that day. These privileges are available for all
accounts other than retirement accounts. The telephone redemption privilege is
not available for shares represented by certificates. If the shares to be
redeemed have been recently purchased by check, ACCESS may delay mailing a
redemption check or wiring redemption proceeds until it confirms that the
purchase check has cleared, usually a period of up to 15 days. If an account has
multiple owners, ACCESS may rely on the instructions of any one owner.
 
  For redemptions authorized by telephone, amounts of $50,000 or less may be
redeemed daily if the proceeds are to be paid by check sent to the shareholders'
address of record and amounts of at least $1,000 and up to $1 million may be
redeemed daily if the proceeds are to be paid by wire sent to the shareholder's
bank account of record. The proceeds must be payable to the shareholder(s) of
record. Proceeds from redemptions to be paid by check will ordinarily be mailed
within three business days to the shareholder's address of record. Proceeds from
redemptions to be paid by wire will ordinarily be wired on the next business day
to the shareholder's bank account of record. This privilege is not available if
the address of record has been changed within 30 days prior to a telephone
redemption request.
 
                                       40
<PAGE>   96
 
The Fund reserves the right at any time to terminate, limit or otherwise modify
this telephone redemption privilege.
 
  REDEMPTION UPON DISABILITY. The Fund will waive the contingent deferred sales
charge on redemptions following the disability of holders of Class B Shares and
Class C Shares. An individual will be considered disabled for this purpose if he
or she meets the definition thereof in Section 72(m)(7) of the Code, which in
pertinent part defines a person as disabled if such person "is unable to engage
in any substantial gainful activity by reason of any medically determinable
physical or mental impairment which can be expected to result in death or to be
of long-continued and indefinite duration." While the Fund does not specifically
adopt the balance of the Code's definition which pertains to furnishing the
Secretary of Treasury with such proof as he or she may require, the Distributor
will require satisfactory proof of disability before it determines to waive the
contingent deferred sales charge on Class B Shares and Class C Shares.
 
  In cases of disability, the contingent deferred sales charges on Class B
Shares and Class C Shares will be waived where the disabled person is either an
individual shareholder or owns the shares as a joint tenant with right of
survivorship or is the beneficial owner of a custodial or fiduciary account, and
where the redemption is made within one year of the initial determination of
disability. This waiver of the contingent deferred sales charge on Class B
Shares and Class C Shares applies to a total or partial redemption, but only to
redemptions of shares held at the time of the initial determination of
disability.
 
  GENERAL REDEMPTION INFORMATION. The Fund may redeem any shareholder account
with a net asset value on the date of the notice of redemption less than the
minimum investment as specified by the Trustees. At least 60 days advance
written notice of any such involuntary redemption is required and the
shareholder is given an opportunity to purchase the required value of additional
shares at the next determined net asset value without sales charge. Any
applicable contingent deferred sales charge will be deducted from the proceeds
of this redemption. Any involuntary redemption may only occur if the shareholder
account is less than the minimum investment due to shareholder redemptions.
 
  REINSTATEMENT PRIVILEGE. Holders of Class A Shares or Class B Shares who have
redeemed shares of the Fund may reinstate any portion or all of the net proceeds
of such redemption in Class A Shares of the Fund. Holders of Class C Shares who
have redeemed shares of the Fund may reinstate any portion or all of the net
proceeds of such redemption in Class C Shares of the Fund with credit given for
any contingent deferred sales charge paid upon such redemption. Such
reinstatement is made at the net asset value 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."
Reinstatement at net asset value is also offered to participants in those
eligible retirement plans held or administered by Van Kampen American Capital
Trust Company for repayment of principal (and interest) on their borrowings on
such plans.

- ------------------------------------------------------------------------------
THE DISTRIBUTION AND SERVICE PLANS
- ------------------------------------------------------------------------------
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan provide
that the Fund may spend a portion of the Fund's average daily net assets
attributable to each class of shares in connection with distribution of the
respective class of shares and in connection with the provision of ongoing
services to shareholders of each class. The Distribution Plan and the Service
Plan are being implemented through an agreement with the Distributor and
sub-agreements between the Distributor and brokers, dealers and financial
intermediaries (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance.
 
  CLASS A SHARES. The Fund may spend an aggregate amount up to 0.25% per year of
the average daily net assets attributable to the Class A Shares of the Fund
pursuant to the Distribution Plan and Service Plan. From such amount, the Fund
may spend up to 0.25% per year of the Fund's average daily net assets
attributable to the Class A Shares pursuant to the Service Plan in connection
with the ongoing provision of services to holders of such shares by the
Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts. The Fund pays
the Distributor the lesser of the balance of the 0.25% not paid to such brokers,
dealers or financial intermediaries or the amount of the Distributor's actual
distribution related expense.
 
  CLASS B SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class B Shares of the Fund pursuant to the
Distribution Plan. In addition, the Fund may spend up to 0.25% per year of the
Fund's average daily net assets attributable to the Class B Shares pursuant to
the Service Plan in connection with the ongoing provision of services to holders
of such shares by the Distributor and by brokers, dealers or financial
intermediaries and in connection with the maintenance of such shareholders'
accounts.
 
  CLASS C SHARES. The Fund may spend up to 0.75% per year of the average daily
net assets attributable to the Class C Shares of the Fund pursuant to the
Distribution Plan. From such amount, the Fund, or the Distributor as agent for
the Fund, pays brokers, dealers or financial intermediaries in connection with
the distribution of the Class C Shares up to 0.75% of the Fund's average daily
net assets attributable to Class C Shares maintained in the Fund more than one
year by such broker's, dealer's or financial intermediary's customers. The Fund
pays the Distributor the lesser of the balance of 0.75% not paid to such
brokers, dealers or financial intermediaries or the amount of the Distributor's
actual distribution related expense attributable to the Class C Shares. In
addition, the Fund may spend up to 0.25% per year of the Fund's average daily
net assets attributable to the Class C Shares pursuant to the Service Plan in
connection with the ongoing provision of services to
 
                                       42
<PAGE>   98
 
holders of such shares by the Distributor and by brokers, dealers or financial
intermediaries and in connection with the maintenance of such shareholders'
accounts.
 
  OTHER INFORMATION. Amounts payable to the Distributor with respect to the
Class A Shares under the Distribution Plan in a given year may not fully
reimburse the Distributor for its actual distribution-related expenses during
such year. In such event, with respect to the Class A Shares, there is no
carryover of such reimbursement obligations to succeeding years.
 
  The Distributor's actual expenses with respect to a class of CDSC Shares (for
purposes of this section, excluding any Class A Shares that may be subject to a
CDSC) for any given year may exceed the amounts payable to the Distributor with
respect to such class of CDSC Shares under the Distribution Plan, the Service
Plan and payments received pursuant to the contingent deferred sales charge. In
such event, with respect to any such class of CDSC Shares, any unreimbursed
expenses will be carried forward and paid by the Fund (up to the amount of the
actual expenses incurred) in future years so long as such Distribution Plan is
in effect. Except as mandated by applicable law, the Fund does not impose any
limit with respect to the number of years into the future that such unreimbursed
expenses may be carried forward (on a Fund level basis). Because such expenses
are accounted on a Fund level basis, in periods of extreme net asset value
fluctuation such amounts with respect to a particular CDSC Share may be greater
or less than the amount of the initial commission (including carrying cost) paid
by the Distributor with respect to such CDSC Share. In such circumstances, a
shareholder of such CDSC Share may be deemed to incur expenses attributable to
other shareholders of such class. The Fund will disclose in its prospectus from
time to time the then current amount of any such unreimbursed expenses with
respect to each class of CDSC Shares expressed as a dollar amount and as a
percent of the Fund's total net assets. As of December 31, 1994, there were
$418,563 and $5,871 of unreimbursed distribution expenses with respect to Class
B Shares and Class C Shares, respectively, representing 0.06% and less than
0.01% of the Fund's total net assets. If the Distribution Plan was terminated or
not continued, the Fund would not be contractually obligated to pay the
Distributor for any expenses not previously reimbursed by the Fund or recovered
through contingent deferred sales charges.
 
  Because the Fund is a series of the Trust, amounts paid to the Distributor as
reimbursement for expenses of one series of the Trust may indirectly benefit the
other funds which are series of the Trust. The Distributor will endeavor to
allocate such expenses among such funds in an equitable manner. The Distributor
will not use the proceeds from the contingent deferred sales charge applicable
to a particular class of CDSC Shares to defray distribution related expenses
attributable to any other class of CDSC Shares. Various federal and state laws
prohibit national banks and some state-chartered commercial banks from
underwriting or dealing in the Fund's shares. In addition, state securities laws
on this issue may differ from the interpretations of federal law, and banks and
financial institutions may be required
 
                                       43
<PAGE>   99
 
to register as dealers pursuant to state law. In the unlikely event that a court
were to find that these laws prevent such banks from providing such services
described above, the Fund would seek alternate providers and expects that
shareholders would not experience any disadvantage.
 
- ------------------------------------------------------------------------------
DISTRIBUTIONS FROM THE FUND
- ------------------------------------------------------------------------------
 
  The Fund's present policy, which may be changed at any time by the Board of
Trustees, is to declare daily and pay monthly distributions of all or
substantially all net investment income of the Fund. Net investment income
consists of all interest income and dividends, less all expenses of the Fund
attributable to the class of shares in question. Net short-term capital gains,
if any, may be distributed throughout the year. Expenses of the Fund are accrued
each day. Net realized long-term capital gains, if any, are expected to be
distributed, to the extent permitted by applicable law, to shareholders at least
annually. Distributions cannot be assured, and the amount of each monthly
distribution may vary.
 
  Distributions with respect to each class of shares will be calculated in the
same manner on the same day and will be in the same amount, except that the
different distribution and service fees and any incremental administrative
expenses relating to each class of shares will be borne exclusively by the
respective class and may cause the distributions relating to the different
classes of shares to differ. Generally, distributions with respect to a class of
shares subject to a higher distribution fee, service fee, or where applicable,
the conversion feature will be lower than distributions with respect to a class
of shares subject to a lower distribution fee, service fee, or not subject to
the conversion feature.
 
  Investors will be entitled to begin receiving dividends on their shares on the
business day after the Fund's transfer agent receives payments for such shares.
However, shares become entitled to dividends on the day the Fund's transfer
agent receives payment for the shares either through a fed wire or NSCC
settlement. Shares remain entitled to dividends through the day such shares are
processed for payment on redemption.
 
  Distribution checks may be sent to parties other than the shareholder in whose
name the account is registered. Persons wishing to utilize this service should
complete the appropriate section of the account application accompanying this
Prospectus or available from Van Kampen American Capital Funds, c/o ACCESS, P.O.
Box 418256, Kansas City, MO 64141-9256. After ACCESS receives this completed
form, distribution checks will be sent to the bank or other person so designated
by such shareholder.
 
  PURCHASE OF ADDITIONAL SHARES WITH DISTRIBUTIONS.  The Fund will automatically
credit monthly distributions and any annual net long-term capital gain
distributions to a shareholder's account in additional shares of the Fund valued
at net asset value, without a sales charge. Unless a shareholder instructs
otherwise, the reinvestment
 
                                       44
<PAGE>   100
 
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.
 
- ------------------------------------------------------------------------------
TAX STATUS
- ------------------------------------------------------------------------------
 
The following discussion reflects applicable federal income tax law, as of the
date of this Prospectus:
 
  FEDERAL INCOME TAXATION. The Fund has qualified and intends to continue to
qualify as a regulated investment company under Subchapter M of the Code. To
qualify as a regulated investment company, the Fund must comply with certain
requirements of the Code relating to, among other things, the source of its
income and diversification of its assets. If the Fund so qualifies and if it
distributes each year to its shareholders at least 90% of its net investment
income (including tax-exempt interest and other taxable income including net
short-term capital gains, but not net capital gains, which are the excess of net
long-term capital gains over net short-term capital losses), it will not be
required to pay federal income taxes on any income distributed to shareholders.
The Fund intends to distribute at least the minimum amount of net investment
income to satisfy the 90% distribution requirement. The Fund will not be subject
to federal income tax on any net capital gain distributed to its shareholders.
In order to avoid a 4% excise tax the Fund will be required to distribute by
December 31 of each year at least 98% of its ordinary income for such year and
at least 98% of its capital gain net income (the latter of which is generally
computed on the basis of the one-year period ending on October 31 of such year),
plus any required distribution amounts that were not distributed in previous
taxable years. For purposes of the excise tax, any ordinary income or capital
gain net income retained by, and taxed in the hands of, the Fund will be treated
as having been distributed.
 
  If the Fund qualifies as a regulated investment company and satisfies the 90%
distribution requirement, and if, at the close of each quarter of the Fund's
taxable year, at least 50% of the total of the Fund's assets consists of
obligations exempt from federal income tax ("tax-exempt obligations"), the Fund
will be qualified to pay exempt-interest dividends to its shareholders to the
extent of its tax-exempt interest income (less expenses applicable thereto).
Exempt-interest dividends are excludable from a shareholder's gross income for
federal income tax purposes, but may be taxable distributions for state, local
and other tax purposes. Exempt-interest dividends are included, however, in
determining what portion, if any, of a person's social security and railroad
retirement benefits will be includable in gross income subject to federal income
tax. Interest expense with respect to indebtedness incurred or continued by a
shareholder to purchase or carry shares of the Fund is not deductible to the
extent that such interest relates to exempt-interest dividends received from the
Fund.
 
                                       45
<PAGE>   101
 
  Distributions of the Fund's investment company taxable income (which does not
include tax-exempt interest income) are taxable to shareholders as ordinary
income whether received in shares or in cash. Shareholders who receive
distributions in the form of additional shares will have a basis for federal
income tax purposes in each such share equal to the value thereof on the
reinvestment date. Distributions of the Fund's net capital gain ("capital gains
dividends"), if any, are taxable to shareholders at the rates applicable to
long-term capital gains regardless of the length of time shares of the Fund have
been held by such shareholders. Distributions in excess of the Fund's earnings
and profits, such as distributions of principal, will first reduce the adjusted
tax basis of the shares held by the shareholders and, after such adjusted tax
basis is reduced to zero, will constitute capital gains to such shareholders
(assuming such shares are held as a capital asset). The Fund will inform
shareholders of the source and tax status of such distributions promptly after
the close of each calendar year. Distributions from the Fund will not be
eligible for the dividends received deduction for corporations.
 
  Exempt-interest dividends allocable to interest received by the Fund on
certain "private activity" obligations issued after August 7, 1986 will be
treated as interest on such obligations and thus will give rise to an item of
tax preference that will increase a shareholder's alternative minimum taxable
income. Unless otherwise provided in regulations, the portion of the Fund's
interest on such "private activity" obligations allocable to shareholders will
correspond to the portion of the Fund's total net tax-exempt income distributed
to shareholders. In addition, for corporations, alternative minimum taxable
income will be increased by a percentage of the amount by which a measure of
income that includes interest on tax-exempt obligations exceeds the amount
otherwise determined to be the alternative minimum taxable income. Accordingly,
investment in the Fund may cause such shareholders to be subject to (or result
in an increased liability under) the alternative minimum tax.
 
  Exempt-interest dividends will not be tax-exempt to the extent made to any
shareholder who is a "substantial user" of the facilities financed by tax-exempt
obligations held by the Fund or "related persons" of such substantial users.
 
  Redemption or resale of shares of the Fund will be a taxable transaction for
federal income tax purposes. Redeeming shareholders will recognize gain or loss
in an amount equal to the difference between their basis in such redeemed shares
of the Fund and the amount received. If such shares are held as a capital asset,
the gain or loss will be a capital gain or loss and will generally be long-term
if such shareholders have held shares for more than one year. Any loss realized
on shares held for six months or less will be disallowed to the extent of any
exempt-interest dividends received with respect to such shares. If such loss is
not entirely disallowed, it will be treated as a long-term capital loss to the
extent of any capital gains dividends received with respect to such shares.

  Some of the Fund's investment practices are subject to special provisions of
the Code that, among other things, may defer the use of certain losses of the
Fund and affect the holding period of the securities held by the Fund and the
character of gains or losses realized by the Fund. These provisions may also
require the Fund to mark-to-market some of the positions in its portfolio (i.e.,
treat them as if they were closed out), which may cause the Fund to recognize
income without receiving cash with which to make distributions in amounts
necessary to satisfy the 90% distribution requirement and the distribution
requirement for avoiding income taxes. The Fund will monitor its transactions
and may make certain tax elections in order to mitigate the effect of these
rules and prevent disqualification of the Fund as a regulated investment
company.
 
  Investments of the Fund in securities issued at a discount or providing for
deferred interest or payment of interest in kind are subject to special tax
rules that will affect the amount, timing and character of distributions to
shareholders. For example, with respect to securities issued at a discount, the
Fund will be required to accrue as income each year a portion of the discount
and to distribute such income each year in order to maintain its qualification
as a regulated investment company and to avoid federal income taxes. In order to
generate sufficient cash to make distributions necessary to satisfy the 90%
distribution requirement and avoid federal income taxes, the Fund may have to
dispose of securities that it would otherwise have continued to hold. A portion
of the discount relating to certain stripped tax-exempt obligations may
constitute taxable income to shareholders.
 
  The Fund's ability to dispose of portfolio securities may be limited by the
requirement for qualification as a regulated investment company that less than
30% of the Fund's gross income be derived from the disposition of securities
held for less than three months.
 
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in such a month and paid in January of the following
year will be treated as having been distributed by the Fund and received by the
shareholders on the December 31 of the year in which the dividend was declared.
In addition, certain other distributions made after the close of a taxable year
of the Fund may be "spilled back" and treated as paid by the Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
shareholders will be treated as having received such dividends in the taxable
year in which the distribution is actually made.
 
  The Fund is required in certain circumstances to withhold 31% of taxable
dividends and certain other payments, including redemptions, paid to
shareholders who do not furnish to the Fund their correct taxpayer
identification number (in the case of individuals, their social security number)
and certain required certifications or who are otherwise subject to backup
withholding.

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

FUND PERFORMANCE
- ------------------------------------------------------------------------------
 
  From time to time advertisements and other sales materials for the Fund may
include information concerning the historical performance of the Fund. Any such
information will include the average total return of the Fund calculated on a
compounded basis for specified periods of time. Such advertisements and sales
material may also include a yield quotation as of a current period. In each
case, such total return and yield information, if any, will be calculated
pursuant to rules established by the SEC and will be computed separately for
each class of the Fund's shares. In lieu of or in addition to total return and
yield calculations, such information may include performance rankings and
similar information from independent organizations such as Lipper Analytical
Services, Inc., Business Week, Forbes or other industry publications.
 
  From time to time, the Fund may include in its sales literature and
shareholder reports a quotation of the current "distribution rate" for each
class of shares of the Fund. Distribution rate is a measure of the level of
income and short-term capital gain dividends, if any, distributed for a
specified period. Distribution rate is determined by annualizing the
distributions per share for a stated period and dividing the result by the
public offering price for the same period. It differs from yield, which is a
measure of the income actually earned by the Fund's investments, and from total
return, which is a measure of the income actually earned by, plus the effect of
any realized and unrealized appreciation or depreciation of, such investments
during a stated period. Distribution rate is, therefore, not intended to be a
complete measure of the Fund's performance. Distribution rate may sometimes be
greater than yield since, for instance, it may not include the effect of
amortization of bond premiums, and may include non-recurring short-term capital
gains and premiums from futures transactions engaged in by the Fund.
Distribution rates will be computed separately for each class of the Fund's
shares.
 
  From time to time, the Fund may compare its performance to certain securities
and unmanaged indices which may have different risk/reward characteristics than
the Fund. Such characteristics may include, but are not limited to, tax
features, guarantees, insurance and the fluctuation of principal and/or return.
In addition, from time to time, the Fund may utilize sales literature that
includes hypotheticals.
 
  Further information about the Fund's performance is contained in the Fund's
Annual Report and the Fund's Statement of Additional Information, each of which
can be obtained without charge by calling (800) 421-5666 ((800) 772-8889 for the

DESCRIPTION OF SHARES OF THE FUND
- ------------------------------------------------------------------------------
 
  The Fund is a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust organized as of May 10, 1995 (the "Trust"). The Fund was
originally organized as a sub-trust of a Massachusetts business trust by a
Declaration of Trust dated August 15, 1985, under the name Van Kampen Merritt
Municipal Income Fund and was reorganized as a series of the Trust on July 31,
1995. Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series.
 
  The authorized capitalization of the Fund consists of an unlimited number of
shares of beneficial interest, without par value, divided into three classes,
designated Class A Shares, Class B Shares and Class C Shares. Each class of
shares represents an interest in the same assets of the Fund and are identical
in all respects except that each class bears certain distribution expenses and
has exclusive voting rights with respect to its distribution fee. See "The
Distribution and Service Plans."
 
  Pursuant to an order of the SEC, the Fund is permitted to issue an unlimited
number of classes of shares. Each class of shares is equal as to earnings,
assets and voting privileges, except as noted above, and each class bears the
expenses related to the distribution of its shares. There are no conversion,
preemptive or other subscription rights, except with respect to the conversion
of Class B Shares into Class A Shares as described above. In the event of
liquidation, each of the shares of the Fund is entitled to its portion of all of
the Fund's net assets after all debt and expenses of the Fund have been paid.
Since Class B Shares and Class C Shares pay higher distribution expenses, the
liquidation proceeds to holders of Class B Shares and Class C Shares are likely
to be lower than to other shareholders.
 
  The Trust does not contemplate holding regular meetings of shareholders to
elect Trustees or otherwise. However, the holders of 10% or more of the
outstanding shares may by written request require a meeting to consider the
removal of Trustees by a vote of a majority of the shares present and voting at
such meeting. The Trust will assist such holders in communicating with other
shareholders of the Fund to the extent required by the 1940 Act. More detailed
information concerning the Trust is set forth in the Statement of Additional
Information.

(1) The pro forma statements are presented as if the Reorganization was
    effective December 31, 1994. The pro forma statements give effect to the
    proposed exchange of stock for assets and liabilities with the VK Fund
    being the surviving entity. The proposed transaction will be accounted for
    in accordance with generally accepted accounting principles as a tax-free
    reorganization. The historical cost basis of the investments is carried
    over to the surviving entity.
(2) The pro forma statement presumes the issuance by the VK Fund of 20,742,395
    Class A shares, 2,568,014 Class B shares, and 523,132 Class C shares in
    exchange for the assets and liabilities of the AC Fund.
(3) Due to the differences in the pricing methodologies of the two funds,
    immediately prior to the Reorganization the investments of the AC Fund will
    be valued on the same basis as the investments of the VK Fund and, as a
    result, the market value of the AC Fund will be increased by approximately
    $1,400,000, or $0.04 per share.
(4) In connection with this transaction, the combined Fund immediately after the
    Reorganization will incur a non-recurring cost associated with the
    combination of approximately $300,500, or $.004 per share.

                             THE FUND AND THE TRUST
 
  The Fund is a separate series of the Trust, an open-end diversified management
investment company. At present, the Fund, Van Kampen American Capital Insured
Tax Free Income Fund, Van Kampen American Capital Tax Free High Income Fund, Van
Kampen American Capital California Insured Tax Free Fund, Van Kampen American
Capital Limited Term Municipal Income Fund, Van Kampen American Capital Florida
Insured Tax Free Income Fund, Van Kampen American Capital New Jersey Tax Free
Income Fund, and Van Kampen American Capital New York Tax Free Income Fund have
been organized as series of the Trust and have commenced investment operations.
Van Kampen American Capital California Tax Free Income Fund, Van Kampen American
Capital Michigan Tax Free Income Fund, Van Kampen American Capital Missouri Tax
Free Income Fund and Van Kampen American Capital Ohio Tax Free Income Fund have
been organized as series of the Trust but have not yet commenced investment
operations. Other series may be organized and offered in the future.
 
  The Trust is an unincorporated business trust established under the laws of
the state of Delaware by an Agreement and Declaration of Trust dated as of May
10, 1995, (the "Declaration of Trust"). The Declaration of Trust permits the
Trustees to create one or more separate investment portfolios and issue a series
of shares for each portfolio. The Trustees can further sub-divide each series of
shares into one or more classes of shares for each portfolio. Each share
represents an equal proportionate interest in the assets of the series with each
other share in such series and no interest in any other series. No series is
subject to the liabilities of any other series. The Declaration of Trust
provides that shareholders are not liable for any liabilities of the Trust or
any of its series, requires inclusion of a clause to that effect in every
agreement entered into by the Trust or any of its series and indemnifies
shareholders against any such liability. The Fund was originally organized as a
sub-trust of a Massachusetts business trust by a Declaration of Trust dated
August 15, 1985, under the name of Van Kampen Merritt Municipal Income Fund and
was reorganized as a series of the Trust on July 31, 1995.
 
  Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series. For example, a change in investment policy for a series would be voted
upon by shareholders of only the series involved. Shares do not have cumulative
voting rights, preemptive rights or any conversion or exchange rights. The Trust
does not contemplate holding regular meetings of shareholders to elect Trustees
or otherwise. However, the holders of 10% or more of the outstanding shares may
by written request require a meeting to consider the removal of Trustees by a
vote of a majority of the shares present and voting at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
series) in any manner without shareholder approval, except that the Trustees may
not adopt any amendment adversely affecting the rights of shareholders of any
series without approval by a majority of the shares of each affected series
present at a meeting of shareholders (or such higher vote as may be required by
the Investment Company Act of 1940, as amended (the "1940 Act") or other
applicable law) and except that the Trustees cannot amend the Declaration of
Trust to impose any liability on shareholders, make any assessment on shares or
impose liabilities on the Trustees without approval from each affected
shareholder or Trustee, as the case may be.
 
  Statements contained in this Statement of Additional Information as to the
contents of any contract or other document referred to are not necessarily

                      INVESTMENT POLICIES AND RESTRICTIONS
 
  The investment objective of the Fund is set forth in the Prospectus under the
caption "Investment Objective and Policies." There can be no assurance that the
Fund will achieve its investment objective.
 
  Fundamental investment restrictions limiting the investments of the Fund
provide that the Fund may not:
 
   1. With respect to 75% of its total assets, purchase any securities (other
      than obligations guaranteed by the United States Government or by its
      agencies or instrumentalities), if, as a result, more than 5% of the
      Fund's total assets (taken at current market value) would then be invested
      in securities of a single
 
                                       B-2
<PAGE>   134
 
      issuer or, if, as a result, the Fund would hold more than 10% of the
      outstanding voting securities of an issuer.
 
   2. Invest more than 25% of its assets in a single industry. (As described in
      the Prospectus, the Fund may from time to time invest more than 25% of its
      assets in a particular segment of the municipal bond market; however, the
      Fund will not invest more than 25% of its assets in industrial development
      bonds in a single industry.)
 
   3. Borrow money, except from banks for temporary purposes and then in amounts
      not in excess of 5% of the total asset value of the Fund, or mortgage,
      pledge, or hypothecate any assets except in connection with a borrowing
      and in amounts not in excess of 10% of the total asset value of the Fund.
      Borrowings may not be made for investment leverage, but only to enable the
      Fund to satisfy redemption requests where liquidation of portfolio
      securities is considered disadvantageous or inconvenient. In this
      connection, the Fund will not purchase portfolio securities during any
      period that such borrowings exceed 5% of the total asset value of the
      Fund. Notwithstanding this investment restriction, the Fund may enter into
      when issued and delayed delivery transactions as described in the
      Prospectus.
 
   4. Make loans of money or property to any person, except to the extent the
      securities in which the Fund may invest are considered to be loans and
      except that the Fund may lend money or property in connection with
      maintenance of the value of, or the Fund's interest with respect to, the
      securities owned by the Fund.
 
   5. Buy any securities "on margin." Neither the deposit of initial or
      maintenance margin in connection with hedging transactions nor short term
      credits as may be necessary for the clearance of transactions is
      considered the purchase of a security on margin.
 
   6. Sell any securities "short," write, purchase or sell puts, calls or
      combinations thereof, or purchase or sell interest rate or other financial
      futures or index contracts or related options, except as hedging or risk
      management transactions in accordance with the requirements of the
      Securities and Exchange Commission and the Commodity Futures Trading
      Commission.
 
   7. Act as an underwriter of securities, except to the extent the Fund may be
      deemed to be an underwriter in connection with the sale of securities held
      in its portfolio.
 
   8. Make investments for the purpose of exercising control or participation in
      management, except to the extent that exercise by the Fund of its rights
      under agreements related to securities owned by the Fund would be deemed
      to constitute such control or participation.
 
   9. Invest in securities of other investment companies, except as part of a
      merger, consolidation or other acquisition and except that the Fund may
      invest up to 10% of its assets in tax-exempt investment companies that
      invest in securities rated comparably to those the Fund may invest in so
      long as the Fund does not own more than 3% of the outstanding voting stock
      of any tax-exempt investment company or securities of any tax-exempt
      investment company aggregating in value more than 5% of the total assets
      of the Fund.
 
  10. Invest in oil, gas or mineral leases or in equity interests in oil, gas,
      or other mineral exploration or development programs.
 
  11. Purchase or sell real estate, commodities or commodity contracts, except
      to the extent the securities the Fund may invest in are considered to be
      interest in real estate, commodities or commodity contracts or to the
      extent the Fund exercises its rights under agreements relating to such
      securities (in which case the Fund may own, hold, foreclose, liquidate or
      otherwise dispose of real estate acquired as a result of a default on a
      mortgage), and except to the extent the options and futures and index
      contracts in which such Funds may invest for hedging and risk management
      purposes are considered to be commodities or commodities contracts.
 
  The Fund may not change any of these investment restrictions as they apply to
the Fund without the approval of the lesser of (i) more than 50% of the Fund's
outstanding shares or (ii) 67% of the Fund's outstanding Shares present at a
meeting at which the holders of more than 50% of the outstanding shares are
 
                                       B-3
<PAGE>   135
 
present in person or by proxy. As long as the percentage restrictions described
above are satisfied at the time of the investment or borrowing, the Fund will be
considered to have abided by those restrictions even if, at a later time, a
change in values or net assets causes an increase or decrease in percentage
beyond that allowed.
 
  The Fund generally will not engage in the trading of securities for the
purpose of realizing short-term profits, but it will adjust its portfolio as
deemed advisable in view of prevailing or anticipated market conditions to
accomplish the Fund's investment objectives. For example, the Fund may sell
portfolio securities in anticipation of a movement in interest rates. Frequency
of portfolio turnover will not be a limiting factor if the Fund considers it
advantageous to purchase or sell securities. Portfolio turnover is calculated by
dividing the lesser of purchases or sales of portfolio securities by the monthly
average value of the securities in the portfolio during the year. Securities,
including options, whose maturity or expiration date at the time of acquisition
were one year or less are excluded from such calculation. The Fund anticipates
that its annual portfolio turnover rate will normally be less than 100%.
 
                      ADDITIONAL INVESTMENT CONSIDERATIONS
 
MUNICIPAL SECURITIES
 
  Municipal securities include long-term obligations, which are often called
municipal bonds, as well as shorter term municipal notes, municipal leases, and
tax-exempt commercial paper. Under normal market conditions, longer term
municipal securities generally provide a higher yield than shorter term
municipal securities, and therefore the Fund generally expects to be invested
primarily in longer term municipal securities. The Fund will, however, invest in
shorter term municipal securities when yields are greater than yields available
on longer term municipal securities, for temporary defensive purposes and when
redemption requests are expected. The two principal classifications of municipal
bonds are "general obligation" and "revenue" or "special obligation" bonds,
which include "industrial revenue bonds." General obligation bonds are secured
by the issuer's pledge of its faith, credit, and taxing power for the payment of
principal and interest. Revenue or special obligation bonds are payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special tax or other specific revenue
source such as from the user of the facility being financed.
 
  Also included within the general category of municipal securities are
participations in lease obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of municipal authorities
of entities used to finance the acquisition of equipment and facilities.
Although lease obligations do not constitute general obligations of the
municipality for which the municipality's taxing power is pledged, a lease
obligation is ordinarily backed by the municipality's covenant to budget for,
appropriate and make the payments due under the lease obligation. However,
certain lease obligations contain "non-appropriation" clauses which provide that
the municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a
yearly basis. In addition to the "non-appropriation" risk, these securities
represent a relatively new type of financing that has not yet developed the
depth of marketability associated with more conventional bonds. Although
"non-appropriation" lease obligations are often secured by the underlying
property, disposition of the property in the event of foreclosure might prove
difficult. There is no limitation on the percentage of the Fund's assets that
may be invested in "non-appropriation" lease obligations. In evaluating such
lease obligations, the Adviser will consider such factors as it deems
appropriate, which factors may include (a) whether the lease can be cancelled,
(b) the ability of the lease obligee to direct the sale of the underlying
assets, (c) the general creditworthiness of the lease obligor, (d) the
likelihood that the municipality will discontinue appropriating funding for the
leased property in the event such property is no longer considered essential by
the municipality, (e) the legal recourse of the lease obligee in the event of
such a failure to appropriate funding and (f) any limitations which are imposed
on the lease obligor's ability to utilize substitute property or services than
those covered by the lease obligation.
 
  Also included in the term municipal securities are participation certificates
issued by state and local governments or authorities to finance the acquisition
of equipment and facilities. They may represent
 
                                       B-4
<PAGE>   136
 
participations in a lease, an installment purchase contract, or a conditional
sales contract. Some municipal leases and participation certificates may not be
readily marketable.
 
  The "issuer" of municipal securities generally is deemed to be the
governmental agency, authority, instrumentality or other political subdivision,
or the non-governmental user of a revenue bond-financed facility, the assets and
revenues of which will be used to meet the payment obligations, or the guarantee
of such payment obligations, of the municipal securities.
 
  The Fund may purchase floating and variable rate demand notes, which are
municipal securities normally having a stated maturity in excess of one year,
but which permit the holder to demand payment of principal at any time, or at
specified intervals. The issuer of such notes normally has a corresponding
right, after a given period, to prepay at its discretion upon notice to the
noteholders the outstanding principal amount of the notes plus accrued interest.
The interest rate on a floating rate demand note is based on a known lending
rate, such as a bank's prime rate, and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is adjusted
automatically at specified intervals. There generally is no secondary market for
these notes, although they are redeemable at face value. Each note purchase by
the Fund will meet the criteria established for the purchase of municipal
securities.
 
  The Fund also may invest up to 15% of its total assets in variable rate
derivative municipal securities such as inverse floaters whose rates vary
inversely with changes in market rates of interest. Such variable rate
derivative municipal securities may pay a rate of interest determined by
applying a multiple to the variable rate. The extent of increases and decreases
in the value of derivative municipal securities whose rates vary inversely with
changes in market rates of interest in response to such changes in market rates
generally will be larger than comparable changes in the value of an equal
principal amount of a fixed rate municipal security having similar credit
quality, redemption provisions and maturity. In addition, the Fund may invest in
derivative municipal securities the terms of which include elements of, or are
similar in effect to, certain Strategic Transactions in which the Fund may
engage. Such municipal securities may by their terms, for example, have economic
characteristics comparable to, among other things, a swap, cap, floor or collar
transaction with respect to such security for a period of time prior to its
stated maturity. See "Additional Investment Considerations -- Strategic
Transactions" in this Statement of Additional Information.
 
  Although the Fund will invest at least 80% of its assets in municipal
securities rated investment grade at the time of investment, municipal
securities, like other debt obligations, are subject to the risk of non-payment.
The ability of issuers of municipal securities to make timely payments of
interest and principal may be adversely impacted in general economic downturns
and as relative governmental cost burdens are allocated and reallocated among
federal, state and local governmental units. Such non-payment would result in a
reduction of income to the Fund, and could result in a reduction in the value of
the municipal security experiencing non-payment and a potential decrease in the
net asset value of the Fund. Issuers of municipal securities might seek
protection under the bankruptcy laws. In the event of bankruptcy of such an
issuer, the Fund could experience delays and limitations with respect to the
collection of principal and interest on such municipal securities and the Fund
may not, in all circumstances, be able to collect all principal and interest to
which it is entitled. To enforce its rights in the event of a default in the
payment of interest or repayment of principal, or both, the Fund may take
possession of and manage the assets securing the issuer's obligations on such
securities, which may increase the Fund's operating expenses and adversely
affect the net asset value of the Fund. Any income derived from the Fund's
ownership or operation of such assets may not be tax-exempt. In addition, the
Fund's intention to qualify as a "regulated investment company" under the
Internal Revenue Code of 1986, as amended (the "Code"), may limit the extent to
which the Fund may exercise its rights by taking possession of such assets,
because as a regulated investment company the Fund is subject to certain
limitations on its investments and on the nature of its income.
 
  The Fund may invest up to 15% of its total assets in illiquid securities,
securities the disposition of which is subject to substantial legal or
contractual restrictions on resale and securities that are not readily
marketable. The sale of restricted and illiquid securities often requires more
time and results in higher brokerage charges or dealer discounts and other
selling expenses than does the sale of securities eligible for trading on
national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale. Restricted securities salable among qualified
 
                                       B-5
<PAGE>   137
 
institutional buyers without restriction pursuant to Rule 144A under the
Securities Act of 1933, as amended, that are determined to be liquid by the
Adviser under guidelines adopted by the Board of Trustees of the Trust (under
which guidelines the Adviser will consider factors such as trading activities
and the availability of price quotations), will not be treated as restricted
securities by the Fund pursuant to such rules. The Fund may, from time to time,
adopt a more restrictive limitation with respect to investment in illiquid and
restricted securities in order to comply with the most restrictive state
securities law, currently 10%. This policy does not include restricted
securities eligible for resale pursuant to Rule 144A under the Securities Act of
1933, as amended, which the Board of Trustees or the Fund's investment adviser
has determined under Board-approved guidelines to be liquid.
 
HIGH YIELD MUNICIPAL SECURITIES
 
  In normal circumstances, at least 80% of the Fund's total assets will be
invested in investment grade tax-exempt municipal securities and up to 20% of
the Fund's total assets may be invested in lower grade tax-exempt municipal
securities. The amount of available information about the financial condition of
municipal securities issuers is generally less extensive than that for corporate
issuers with publicly traded securities and the market for tax-exempt municipal
securities is considered to be generally less liquid than the market for
corporate debt obligations. Liquidity relates to the ability of a Fund to sell a
security in a timely manner at a price which reflects the value of that
security. As discussed below, the market for lower grade tax-exempt municipal
securities is considered generally to be less liquid than the market for
investment grade tax-exempt municipal securities. Further, municipal securities
in which the Fund may invest include special obligation bonds, lease
obligations, participation certificates and variable rate instruments. The
market for such securities may be particularly less liquid. The relative
illiquidity of some of the Fund's portfolio securities may adversely affect the
ability of the Fund to dispose of such securities in a timely manner and at a
price which reflects the value of such security in the Adviser's judgment.
Although the issuer of some such municipal securities may be obligated to redeem
such securities at face value, such redemption could result in capital losses to
the Fund to the extent that such municipal securities were purchased by the Fund
at a premium to face value. The market for less liquid securities tends to be
more volatile than the market for more liquid securities and market values of
relatively illiquid securities may be more susceptible to change as a result of
adverse publicity and investor perceptions than are the market values of higher
grade, more liquid securities.
 
  The Fund's net asset value will change with changes in the value of its
portfolio securities. Because the Fund will invest primarily in fixed income
municipal securities, the Fund's net asset value can be expected to change as
general levels of interest rates fluctuate. When interest rates decline, the
value of a portfolio invested in fixed income securities can be expected to
rise. Conversely, when interest rates rise, the value of a portfolio invested in
fixed income securities can be expected to decline. Net asset value and market
value may be volatile due to the Fund's investment in lower grade and less
liquid municipal securities. Volatility may be greater during periods of general
economic uncertainty.
 
  The Adviser values the Fund's investments pursuant to guidelines adopted and
periodically reviewed by the Board of Trustees. To the extent that there is no
established retail market for some of the securities in which the Fund may
invest, there may be relatively inactive trading in such securities and the
ability of the Adviser to accurately value such securities may be adversely
affected. During periods of reduced market liquidity and in the absence of
readily available market quotations for securities held in the Fund's portfolio,
the responsibility of the Adviser to value the Fund's securities becomes more
difficult and the Adviser's judgment may play a greater role in the valuation of
the Fund's securities due to the reduced availability of reliable objective
data. To the extent that the Fund invests in illiquid securities and securities
which are restricted as to resale, the Fund may incur additional risks and
costs. Illiquid and restricted securities are particularly difficult to dispose
of.
 
  Lower grade tax-exempt municipal securities generally involve greater credit
risk than higher grade municipal securities. A general economic downturn or a
significant increase in interest rates could severely disrupt the market for
lower grade tax-exempt municipal securities and adversely affect the market
value of such securities. In addition, in such circumstances, the ability of
issuers of lower grade tax-exempt municipal securities to repay principal and to
pay interest, to meet projected financial goals and to obtain additional
financing may be adversely affected. Such consequences could lead to an
increased incidence of default for
 
                                       B-6
<PAGE>   138
 
such securities and adversely affect the value of the lower grade tax-exempt
municipal securities in the Fund's portfolio and thus the Fund's net asset
value. The secondary market prices of lower grade tax-exempt municipal
securities are less sensitive to changes in interest rates than are those for
higher rated tax-exempt municipal securities, but are more sensitive to adverse
economic changes or individual issuer developments. Adverse publicity and
investor perceptions, whether or not based on rational analysis, may also affect
the value and liquidity of lower grade tax-exempt municipal securities.
 
  Yields on the Fund's portfolio securities can be expected to fluctuate over
time. In addition, periods of economic uncertainty and changes in interest rates
can be expected to result in increased volatility of the market prices of the
lower grade tax-exempt municipal securities in the Fund's portfolio and thus in
the net asset value of the Fund. Net asset value and market value may be
volatile due to the Fund's investment in lower grade and less liquid municipal
securities. Volatility may be greater during periods of general economic
uncertainty. The Fund may incur additional expenses to the extent it is required
to seek recovery upon a default in the payment of interest or a repayment of
principal on its portfolio holdings, and the Fund may be unable to obtain full
recovery thereof. In the event that an issuer of securities held by the Fund
experiences difficulties in the timely payment of principal or interest and such
issuer seeks to restructure the terms of its borrowings, the Fund may incur
additional expenses and may determine to invest additional capital with respect
to such issuer or the project or projects to which the Fund's portfolio
securities relate. Recent and proposed legislation may have an adverse impact on
the market for lower grade tax-exempt municipal securities. Recent legislation
requires federally-insured savings and loan associations to divest their
investments in lower grade bonds. Other legislation has been proposed which, if
enacted, could have an adverse impact on the market for lower grade tax-exempt
municipal securities.
 
  The Fund will rely on the Adviser's judgment, analysis and experience in
evaluating the creditworthiness of an issue. In this evaluation, the Adviser
will take into consideration, among other things, the issuer's financial
resources, its sensitivity to economic conditions and trends, its operating
history, the quality of the issuer's management and regulatory matters. The
Adviser also may consider, although it does not rely primarily on, the credit
ratings of S&P and Moody's in evaluating tax-exempt municipal securities. Such
ratings evaluate only the safety of principal and interest payments, not market
value risk. Additionally, because the creditworthiness of an issuer may change
more rapidly than is able to be timely reflected in changes in credit ratings,
the Adviser continuously monitors the issuers of tax-exempt municipal securities
held in the Fund's portfolio. The Fund may, if deemed appropriate by the
Adviser, retain a security whose rating has been downgraded below B- by S&P or
below B3 by Moody's, or whose rating has been withdrawn.
 
  Because issuers of lower grade tax-exempt municipal securities frequently
choose not to seek a rating of their municipal securities, the Adviser will be
required to determine the relative investment quality of many of the municipal
securities in the Fund's portfolio. Further, because the Fund may invest up to
20% of its total assets in these lower grade municipal securities, achievement
by the Fund of its investment objective may be more dependent upon the Adviser's
investment analysis than would be the case if the Fund were investing
exclusively in higher grade municipal securities. The relative lack of financial
information available with respect to issuers of municipal securities may
adversely affect the Adviser's ability to successfully conduct the required
investment analysis.
 
STRATEGIC TRANSACTIONS
 
  The Fund may, but is not required to, utilize various other investment
strategies as described below to hedge various market risks (such as interest
rates and broad or specific market movements) or to manage the effective
maturity or duration of the Fund's fixed-income securities. Such strategies are
generally accepted by modern portfolio managers and are regularly utilized by
many mutual funds and other institutional investors. Techniques and instruments
may change over time as new instruments and strategies are developed or
regulatory changes occur.
 
  In the course of pursuing these investment strategies, the Fund may purchase
and sell derivative instruments such as exchange-listed and over-the-counter put
and call options on securities, fixed-income indices and other financial
instruments, purchase and sell financial futures contracts and options thereon,
enter into various interest rate transactions such as swaps, caps, floors or
collars (collectively, all the above are called
 
                                       B-7
<PAGE>   139
 
"Strategic Transactions"). Strategic Transactions may be used to attempt to
protect against possible changes in the market value of securities held in or to
be purchased for the Fund's portfolio resulting from securities markets
fluctuations, to protect the Fund's unrealized gains in the value of its
portfolio securities, to facilitate the sale of such securities for investment
purposes, to manage the effective maturity or duration of the Fund's portfolio,
or to establish a position in the derivatives markets as a temporary substitute
for purchasing or selling particular securities.
 
  Any or all of these investment techniques may be used at any time and there is
no particular strategy that dictates the use of one technique rather than
another, as use of any Strategic Transaction is a function of numerous variables
including market conditions. The ability of the Fund to utilize these Strategic
Transactions successfully will depend on the Adviser's ability to predict
pertinent market movements, which cannot be assured. The Fund will comply with
applicable regulatory requirements when implementing these strategies,
techniques and instruments. Strategic Transactions involving financial futures
and options thereon will be purchased, sold or entered into only for bona fide
hedging, risk management or portfolio management purposes and not for
speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale or purchase of portfolio securities at inopportune times or
for prices other than current market values, limit the amount of appreciation
the Fund can realize on its investments or cause the Fund to hold a security it
might otherwise sell. The use of options and futures transactions entails
certain other risks. In particular, the variable degree of correlation between
price movements of futures contracts and price movements in the related
portfolio position of the Fund creates the possibility that losses on the
hedging instrument may be greater than gains in the value of the Fund's
position. In addition, futures and options markets may not be liquid in all
circumstances and certain over-the-counter options may have no markets. As a
result, in certain markets, the Fund might not be able to close out a
transaction without incurring substantial losses, if at all. Although the use of
futures and options transactions for hedging should tend to minimize the risk of
loss due to a decline in the value of the hedged position, at the same time they
tend to limit any potential gain which might result from an increase in value of
such position. Finally, the daily variation margin requirements for futures
contracts would create a greater ongoing potential financial risk than would
purchases of options, where the exposure is limited to the cost of the initial
premium. Losses resulting from the use of Strategic Transactions would reduce
net asset value, and possibly income, and such losses can be greater than if the
Strategic Transactions had not been utilized. Income earned or deemed to be
earned, if any, by the Fund from its Strategic Transactions will generally be
taxable income of the Fund. See "Tax Status" in the Prospectus.
 
  GENERAL CHARACTERISTICS OF OPTIONS.   Put options and call options typically
have similar structural characteristics and operational mechanics regardless of
the underlying instrument on which they are purchased or sold. Thus, the
following general discussion relates to each of the particular types of options
discussed in greater detail below. In addition, many Strategic Transactions
involving options require segregation of Fund assets in special accounts, as
described below under "Use of Segregated and Other Special Accounts."
 
  A put option gives the purchaser of the option, upon payment of a premium, the
right to sell, and the writer the obligation to buy, the underlying security,
commodity, index, or other instrument at the exercise price. For instance, the
Fund's purchase of a put option on a security might be designed to protect its
holdings in the underlying instrument (or, in some cases, a similar instrument)
against a substantial decline in the market value by giving the Fund the right
to sell such instrument at the option exercise price. A call option, upon
payment of a premium, gives the purchaser of the option the right to buy, and
the seller the obligation to sell, the underlying instrument at the exercise
price. The Fund's purchase of a call option on a security, financial future,
index, or other instrument might be intended to protect the Fund against an
increase in the price of the underlying instrument that it intends to purchase
in the future by fixing the price at which it may purchase such instrument. An
American style put or call option may be exercised at any time during the option
period while a European style put or call option may be exercised only upon
expiration or during a fixed period prior thereto. The Fund is authorized to
purchase and sell exchange listed options and over-the-counter options
 
                                       B-8
<PAGE>   140
 
("OTC options"). Exchange listed options are issued by a regulated intermediary
such as the Options Clearing Corporation ("OCC"), which guarantees the
performance of the obligations of the parties to such options. The discussion
below uses the OCC as a paradigm, but is also applicable to other financial
intermediaries.
 
  With certain exceptions, OCC issued and exchange listed options generally
settle by physical delivery of the underlying security or currency, although in
the future cash settlement may become available. Index options and Eurodollar
instruments are cash settled for the net amount, if any, by which the option is
"in-the-money" (i.e., where the value of the underlying instrument exceeds, in
the case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed options are closed by entering into
offsetting purchase or sale transactions that do not result in ownership of the
new option.
 
  The Fund's ability to close out its position as a purchaser or seller of an
OCC or exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. Among the possible reasons for the absence of a
liquid option market on an exchange are: (i) insufficient trading interest in
certain options; (ii) restrictions on transactions imposed by an exchange; (iii)
trading halts, suspensions or other restrictions imposed with respect to
particular classes or series of options or underlying securities including
reaching daily price limits; (iv) interruption of the normal operations of the
OCC or an exchange; (v) inadequacy of the facilities of an exchange or OCC to
handle current trading volume; or (vi) a decision by one or more exchanges to
discontinue the trading of options (or a particular class or series of options),
in which event the relevant market for that option on that exchange would cease
to exist, although outstanding options on that exchange would generally continue
to be exercisable in accordance with their terms.
 
  The hours of trading for listed options may not coincide with the hours during
which the underlying financial instruments are traded. To the extent that the
option markets close before the markets for the underlying financial
instruments, significant price and rate movements can take place in the
underlying markets that cannot be reflected in the option markets.
 
  OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC option, including such terms as method of settlement, term, exercise price,
premium, guarantees and security, are set by negotiation of the parties. The
Fund will only sell OTC options that are subject to a buy-back provision
permitting the Fund to require the Counterparty to sell the option back to the
Fund at a formula price within seven days. The Fund expects generally to enter
into OTC options that have cash settlement provisions, although it is not
required to do so.
 
  Unless the parties provide for it, there is no central clearing or guaranty
function in an OTC option. As a result, if the Counterparty fails to make or
take delivery of the security, or other instrument underlying an OTC option it
has entered into with the Fund or fails to make a cash settlement payment due in
accordance with the terms of that option, the Fund will lose any premium it paid
for the option as well as any anticipated benefit of the transaction.
Accordingly, the Adviser must assess the creditworthiness of each such
Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be satisfied.
The Fund will engage in OTC option transactions only with United States
government securities dealers recognized by the Federal Reserve Bank of New York
as "primary dealers", or broker dealers, domestic or foreign banks or other
financial institutions which have received (or the guarantors of the obligation
of which have received) a short-term credit rating of "A-1" from S&P or "P-1"
from Moody's or an equivalent rating from any other nationally recognized
statistical rating organization ("NRSRO"). The staff of the SEC currently takes
the position that, in general, OTC options on securities other than U.S.
Government securities purchased by the Fund, and portfolio securities "covering"
the amount of the Fund's obligation pursuant to an OTC option sold by it (the
cost of the sell-back plus the in-the-money amount, if any) are illiquid, and
are subject to the Fund's limitation on investing no more than 15% of its assets
in illiquid securities.

  If the Fund sells a call option, the premium that it receives may serve as a
partial hedge, to the extent of the option premium, against a decrease in the
value of the underlying securities or instruments in its portfolio or will
increase the Fund's income. The sale of put options can also provide income.
 
  The Fund may purchase and sell call options on securities, including U.S.
Treasury and agency securities, municipal obligations, mortgage-backed
securities and Eurodollar instruments that are traded on U.S. and foreign
securities exchanges and in the over-the-counter markets. All calls sold by the
Fund must be "covered" (i.e., the Fund must own the securities or futures
contract subject to the call) or must meet the asset segregation requirements
described below as long as the call is outstanding. Even though the Fund will
receive the option premium to help protect it against loss, a call sold by the
Fund exposes the Fund during the term of the option to possible loss of
opportunity to realize appreciation in the market price of the underlying
security or instrument and may require the Fund to hold a security or instrument
which it might otherwise have sold.
 
  The Fund may purchase and sell put options on securities including U.S.
Treasury and agency securities, mortgage-backed securities, municipal
obligations and Eurodollar instruments (whether or not it holds the above
securities in its portfolio.) The Fund will not sell put options if, as a
result, more than 50% of the Fund's assets would be required to be segregated to
cover its potential obligations under such put options other than those with
respect to futures and options thereon. In selling put options, there is a risk
that the Fund may be required to buy the underlying security at a
disadvantageous price above the market price.
 
  GENERAL CHARACTERISTICS OF FUTURES.  The Fund may enter into financial futures
contracts or purchase or sell put and call options on such futures as a hedge
against anticipated interest rate or fixed-income market changes, for duration
management and for risk management purposes. Futures are generally bought and
sold on the commodities exchanges where they are listed with payment of initial
and variation margin as described below. The purchase of a futures contract
creates a firm obligation by the Fund, as purchaser, to take delivery from the
seller the specific type of financial instrument called for in the contract at a
specific future time for a specified price (or, with respect to index futures
and Eurodollar instruments, the net cash amount). The sale of a futures contract
creates a firm obligation by the Fund, as seller, to deliver to the buyer the
specific type of financial instrument called for in the contract at a specific
future time for a specified price (or, with respect to index futures and
Eurodollar instruments, the net cash amount). Options on futures contracts are
similar to options on securities except that an option on a futures contract
gives the purchaser the right in return for the premium paid to assume a
position in a futures contract and obligates the seller to deliver such option.
 
  The Fund's use of financial futures and options thereon will in all cases be
consistent with applicable regulatory requirements and in particular the rules
and regulations of the Commodity Futures Trading Commission and will be entered
into only for bona fide hedging, risk management (including duration management)
or other portfolio management purposes. Typically, maintaining a futures
contract or selling an option thereon requires the Fund to deposit with a
financial intermediary as security for its obligations an amount of cash or
other specified assets (initial margin) which initially is typically 1% to 10%
of the face amount of the contract (but may be higher in some circumstances).
Additional cash or assets (variation margin) may be required to be deposited
thereafter on a daily basis as the mark to market value of the contract
fluctuates. The purchase of options on financial futures involves payment of a
premium for the option without any further obligation on the part of the Fund.
If the Fund exercises an option on a futures contract it will be obligated to
post initial margin (and potential subsequent variation margin) for the
resulting futures position just as it would for any position. Futures contracts
and options thereon are generally settled by entering into an offsetting
transaction but there can be no assurance that the position can be offset prior
to settlement at an advantageous price nor that delivery will occur.
 
  The Fund will not enter into a futures contract or related option (except for
closing transactions) if, immediately thereafter, the sum of the amount of its
initial margin and premiums on open futures contracts and options thereon would
exceed 5% of the Fund's total assets (taken at current value); however, in the
case of an option that is in-the-money at the time of the purchase, the
in-the-money amount may be excluded in calculating the 5% limitation. The
segregation requirements with respect to futures contracts and options thereon
are described below.
 
                                      B-10
<PAGE>   142
 
  OPTIONS ON SECURITIES INDICES AND OTHER FINANCIAL INDICES.  The Fund also may
purchase and sell call and put options on securities indices and other financial
indices and in so doing can achieve many of the same objectives it would achieve
through the sale or purchase of options on individual securities or other
instruments. Options on securities indices and other financial indices are
similar to options on a security or other instrument except that, rather than
settling by physical delivery of the underlying instrument, they settle by cash
settlement, i.e., an option on an index gives the holder the right to receive,
upon exercise of the option, an amount of cash if the closing level of the index
upon which the option is based exceeds, in the case of a call, or is less than,
in the case of a put, the exercise price of the option (except if, in the case
of an OTC option, physical delivery is specified). This amount of cash is equal
to the excess of the closing price of the index over the exercise price of the
option, which also may be multiplied by a formula value. The seller of the
option is obligated, in return for the premium received, to make delivery of
this amount. The gain or loss on an option on an index depends on price
movements in the instruments making up the market, market segment, industry or
other composite on which the underlying index is based, rather than price
movements in individual securities, as is the case with respect to options on
securities.
 
  COMBINED TRANSACTIONS.  The Fund may enter into multiple transactions,
including multiple options transactions, multiple futures transactions and
multiple interest rate transactions and any combination of futures, options and
interest rate transactions ("component" transactions), instead of a single
Strategic Transaction, as part of a single or combined strategy when, in the
opinion of the Adviser, it is in the best interests of the Fund to do so. A
combined transaction will usually contain elements of risk that are present in
each of its component transactions. Although combined transactions are normally
entered into based on the Adviser's judgment that the combined strategies will
reduce risk or otherwise more effectively achieve the desired portfolio
management goal, it is possible that the combination will instead increase such
risks or hinder achievement of the portfolio management objective.
 
  SWAPS, CAPS, FLOORS AND COLLARS.  Among the Strategic Transactions into which
the Fund may enter are interest rate and index swaps and the purchase or sale of
related caps, floors and collars. The Fund expects to enter into these
transactions primarily to preserve a return or spread on a particular investment
or portion of its portfolio, as a duration management technique or to protect
against any increase in the price of securities the Fund anticipates purchasing
at a later date. The Fund intends to use these transactions as hedges and not as
speculative investments and will not sell interest rate caps or floors where it
does not own securities or other instruments providing the income stream the
Fund may be obligated to pay. Interest rate swaps involve the exchange by the
Fund with another party of their respective commitments to pay or receive
interest, e.g., an exchange of floating rate payments for fixed rate payments
with respect to a notional amount of principal. An index swap is an agreement to
swap cash flows on a notional amount based on changes in the values of the
reference indices. The purchase of a cap entitles the purchaser to receive
payments on a notional principal amount from the party selling such cap to the
extent that a specified index exceeds a predetermined interest rate or amount.
The purchase of a floor entitles the purchaser to receive payments on a notional
principal amount from the party selling such floor to the extent that a
specified index falls below a predetermined interest rate or amount. A collar is
a combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates or values.
 
  The Fund will usually enter into swaps on a net basis, i.e., the two payment
streams are netted out in a cash settlement on the payment date or dates
specified in the instrument, with the Fund receiving or paying, as the case may
be, only the net amount of the two payments. Inasmuch as these swaps, caps,
floors and collars are entered into for good faith hedging purposes, the Adviser
and the Fund believe such obligations do not constitute senior securities under
the 1940 Act and, accordingly, will not treat them as being subject to its
borrowing restrictions. The Fund will not enter into any swap, cap, floor or
collar transaction unless, at the time of entering into such transaction, the
unsecured long-term debt of the Counterparty, combined with any credit
enhancements, is rated at least "A" by S&P or Moody's or has an equivalent
equity rating from an NRSRO or is determined to be of equivalent credit quality
by the Adviser. If there is a default by the Counterparty, the Fund may have
contractual remedies pursuant to the agreements related to the transaction. The
swap market has grown substantially in recent years with a large number of banks
and investment banking firms acting both as principals and agents utilizing
standardized swap documentation. As a result, the swap
 
                                      B-11
<PAGE>   143
 
market has become relatively liquid. Caps, floors and collars are more recent
innovations for which standardized documentation has not yet been fully
developed and, accordingly, they are less liquid than swaps.
 
  USE OF SEGREGATED AND OTHER SPECIAL ACCOUNTS.  Many Strategic Transactions, in
addition to other requirements, require that the Fund segregate liquid
high-grade assets with its custodian to the extent Fund obligations are not
otherwise "covered" through ownership of the underlying security, financial
instrument or currency. In general, either the full amount of any obligation by
the Fund to pay or deliver securities or assets must be covered at all times by
the securities, instruments or currency required to be delivered, or, subject to
any regulatory restrictions, an amount of cash or liquid high-grade securities
at least equal to the current amount of the obligation must be segregated with
the custodian. The segregated assets cannot be sold or transferred unless
equivalent assets are substituted in their place or it is no longer necessary to
segregate them. For example, a call option written by the Fund will require the
Fund to hold the securities subject to the call (or securities convertible into
the needed securities without additional consideration) or to segregate liquid
high-grade securities sufficient to purchase and deliver the securities if the
call is exercised. A call option sold by the Fund on an index will require the
Fund to own portfolio securities which correlate with the index or to segregate
liquid high-grade assets equal to the excess of the index value over the
exercise price on a current basis. A put option written by the Fund requires the
Fund to segregate liquid, high-grade assets equal to the exercise price.
 
  OTC options entered into by the Fund, including those on securities, financial
instruments or indices and OCC issued and exchange listed index options, will
generally provide for cash settlement. As a result, when the Fund sells these
instruments it will only segregate an amount of assets equal to its accrued net
obligations, as there is no requirement for payment or delivery of amounts in
excess of the net amount. These amounts will equal 100% of the exercise price in
the case of a non cash-settled put, the same as an OCC guaranteed listed option
sold by the Fund, or the in-the-money amount plus any sell-back formula amount
in the case of a cash-settled put or call. In addition, when the Fund sells a
call option on an index at a time when the in-the-money amount exceeds the
exercise price, the Fund will segregate, until the option expires or is closed
out, cash or cash equivalents equal in value to such excess. OCC issued and
exchange listed options sold by the Fund other than those above generally settle
with physical delivery, and the Fund will segregate an amount of assets equal to
the full value of the option. OTC options settling with physical delivery, or
with an election of either physical delivery or cash settlement, will be treated
the same as other options settling with physical delivery.
 
  In the case of a futures contract or an option thereon, the Fund must deposit
initial margin and possible daily variation margin in addition to segregating
assets sufficient to meet its obligation to purchase or provide securities or
currencies, or to pay the amount owed at the expiration of an index- based
futures contract. Such assets may consist of cash, cash equivalents, liquid debt
or equity securities or other acceptable assets.
 
  With respect to swaps, the Fund will accrue the net amount of the excess, if
any, of its obligations over its entitlements with respect to each swap on a
daily basis and will segregate an amount of cash or liquid high-grade securities
having a value equal to the accrued excess. Caps, floors and collars require
segregation of assets with a value equal to the Fund's net obligation, if any.
 
  Strategic Transactions may be covered by other means when consistent with
applicable regulatory policies. The Fund may also enter into offsetting
transactions so that its combined position, coupled with any segregated assets,
equals its net outstanding obligation in related options and Strategic
Transactions. For example, the Fund could purchase a put option if the strike
price of that option is the same or higher than the strike price of a put option
sold by the Fund. Moreover, instead of segregating assets if the Fund held a
futures or forward contract, it could purchase a put option on the same futures
or forward contract with a strike price as high or higher than the price of the
contract held. Other Strategic Transactions may also be offset in combinations.
If the offsetting transaction terminates at the time of or after the primary
transaction no segregation is required, but if it terminates prior to such time,
assets equal to any remaining obligation would need to be segregated.
 
  The Fund's activities involving Strategic Transactions may be limited by the
requirements of Subchapter M of the Code for qualification as a regulated
investment company. See "Tax Status" in the Prospectus.

                  DESCRIPTION OF MUNICIPAL SECURITIES RATINGS
 
  STANDARD & POOR'S RATINGS GROUP--A brief description of the applicable
Standard & Poor's Ratings Group (S&P) rating symbols and their meanings (as
published by S&P) follows:
 
     1.  DEBT
 
          A Standard & Poor's corporate or municipal debt rating is a current
     assessment of the creditworthiness of an obligor with respect to a specific
     obligation. This assessment may take into consideration obligors such as
     guarantors, insurers, or lessees.
 
          The debt rating is not a recommendation to purchase, sell or hold a
     security, inasmuch as it does not comment as to market price or suitability
     for a particular investor.
 
          The ratings are based on current information furnished by the issuer
     or obtained by S&P from other sources it considers reliable. S&P does not
     perform an audit in connection with any rating and may, on occasion, rely
     on unaudited financial information. The ratings may be changed, suspended,
     or withdrawn as a result of changes in, or unavailability of, such
     information, or based on other circumstances.
 
        The ratings are based, in varying degrees, on the following
considerations:
 
       1. Likelihood of default--capacity and willingness of the obligor as to
          the timely payment of interest and repayment of principal in
          accordance with the terms of the obligation;
 
       2. Nature of and provisions of the obligation;
 
       3. Protection afforded by, and relative position of, the obligation in
          the event of bankruptcy, reorganization, or other arrangement under
          the laws of bankruptcy and other laws affecting creditors' rights.
 
<TABLE>
    <S>       <C>
    AAA       Debt rated 'AAA' has the highest rating assigned by S&P. Capacity to pay
              interest and repay principal is extremely strong.
 
    AA        Debt rated 'AA' has a very strong capacity to pay interest and repay principal
              and differs from the higher rated issues only in small degree.
 
    A         Debt rated 'A' has a strong capacity to pay interest and repay principal
              although it is somewhat more susceptible to the adverse effects of changes in
              circumstances and economic conditions than debt in higher rated categories.
 
    BBB       Debt rated 'BBB' is regarded as having an adequate capacity to pay interest and
              repay principal. Whereas it normally exhibits adequate protection parameters,
              adverse economic conditions or changing circumstances are more likely to lead
              to a weakened capacity to pay interest and repay principal for debt in this
              category than in higher rated categories.
 
    BB        Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded, on balance, as
    B         predominantly speculative with respect to capacity to pay interest and repay
    CCC       principal. 'BB' indicates the least degree of speculation and 'C' the highest.
    CC        While such debt will likely have some quality and protective characteristics,
    C         these are outweighed by large uncertainties or large exposures to adverse
              conditions.
 
    BB        Debt rated 'BB' has less near-term vulnerability to default than other
              speculative issues. However, it faces major ongoing uncertainties or exposure
              to adverse business, financial, or economic conditions which could lead to
              inadequate capacity to meet timely interest and principal payments. The 'BB'
              rating category is also used for debt subordinated to senior debt that is
              assigned an actual or implied 'BBB-' rating.
</TABLE>
 
                                      B-13
<PAGE>   145
 
<TABLE>
    <S>       <C>
    B         Debt rated 'B' has a greater vulnerability to default but currently has the
              capacity to meet interest payments and principal repayments. Adverse business,
              financial, or economic conditions will likely impair capacity or willingness to
              pay interest and repay principal. The 'B' rating category is also used for debt
              subordinated to senior debt that is assigned an actual or implied 'BB' or 'BB-'
              rating.
 
    CCC       Debt rated 'CCC' has a currently identifiable vulnerability to default, and is
              dependent upon favorable business, financial, and economic conditions to meet
              timely payment of interest and repayment of principal. In the event of adverse
              business, financial, or economic conditions, it is not likely to have the
              capacity to pay interest and repay principal. The 'CCC' rating category is also
              used for debt subordinated to senior debt that is assigned an actual or implied
              'B' or 'B-' rating.
 
    CC        The rating 'CC' typically is applied to debt subordinated to senior debt that
              is assigned an actual or implied 'CCC' rating.
 
    C         The rating 'C' typically is applied to debt subordinated to senior debt which
              is assigned an actual or implied 'CCC-' debt rating. The 'C' rating may be used
              to cover a situation where a bankruptcy petition has been filed, but debt
              service payments are continued.
 
    CI        The rating 'CI' is reserved for income bonds on which no interest is being
              paid.
 
    D         Debt rated 'D' is in payment default. The 'D' rating category is used when
              interest payments or principal payments are not made on the date due even if
              the applicable grace period has not expired, unless S&P believes that such
              payments will be made during such grace period. The 'D' rating also will be
              used upon the filing of a bankruptcy petition if debt service payments are
              jeopardized.
 
              PLUS (+) or MINUS (-): The ratings from 'AA' to 'CCC' may be modified
              by the addition of a plus or minus sign to show relative standing
              within the major categories.
 
    C         The letter "c" indicates that the holder's option to tender the security for
              purchase may be canceled under certain prestated conditions enumerated in the
              tender option documents.
 
    I         The letter "i" indicates the rating is implied. Such ratings are assigned only
              on request to entities that do not have specific debt issues to be rated. In
              addition, implied ratings are assigned to governments that have not requested
              explicit ratings for specific debt issues. Implied ratings on governments
              represent the sovereign ceiling or upper limit for ratings on specific debt
              issues of entities domiciled in the country.
 
    L         The letter "L" indicates that the rating pertains to the principal amount of
              those bonds to the extent that the underlying deposit collateral is federally
              insured and interest is adequately collateralized. In the case of certificates
              of deposit, the letter "L" indicates that the deposit, combined with other
              deposits being held in the same right and capacity, will be honored for
              principal and accrued pre-default interest up to the federal insurance limits
              within 30 days after closing of the insured institution or, in the event that
              the deposit is assumed by a successor insured institution, upon maturity.
 
    P         The letter "p" indicates that the rating is provisional. A provisional rating
              assumes the successful completion of the project being financed by the debt
              being rated and indicates that payment of debt service requirements is largely
              or entirely dependent upon the successful and timely completion of the project.
              This rating, however, while addressing credit quality subsequent to completion
              of the project, makes no comment on the likelihood of, or the risk of default
              upon failure of, such completion. The investor should exercise his own
              judgement with respect to such likelihood and risk.
 
              *Continuance of the rating is contingent upon S&P's receipt of an executed copy
              of the escrow agreement or closing documentation confirming investments and
              cash flows.
</TABLE>
 
                                      B-14
<PAGE>   146
 
<TABLE>
    <S>       <C>
    NR        Indicates that no public rating has been requested, that there is insufficient
              information on which to base a rating, or that S&P does not rate a particular
              type of obligation as a matter of policy.
 
              DEBT OBLIGATIONS OF ISSUERS OUTSIDE THE UNITED STATES AND ITS TERRITORIES are
              rated on the same basis as domestic corporate and municipal issues. The ratings
              measure the creditworthiness of the obligor but do not take into account
              currency exchange and related uncertainties.
</TABLE>
 
  BOND INVESTMENT QUALITY STANDARDS: Under present commercial bank regulations
issued by the Comptroller of the Currency, bonds rated in the top four
categories ("AAA", "AA", "A", "BBB", commonly known as "investment grade"
ratings) are generally regarded as eligible for bank investment. In addition,
the laws of various states governing legal investments impose certain rating or
other standards for obligations eligible for investment by savings banks, trust
companies, insurance companies, and fiduciaries generally.
 
     2.  MUNICIPAL NOTES
 
          A S&P note rating reflects the liquidity factors and market-access
     risks unique to notes. Notes maturing in 3 years or less will likely
     receive a note rating. Notes maturing beyond 3 years will most likely
     receive a long-term debt rating. The following criteria will be used in
     making that assessment:
 
          -- Amortization schedule (the larger the final maturity relative to
             other maturities, the more likely the issue is to be treated as a
             note).
 
          -- Source of payment (the more the issue depends on the market for its
             refinancing, the more likely it is to be treated as a note).
 
        The note rating symbols and definitions are as follows:
 
<TABLE>
    <S>       <C>
    SP-1      Strong capacity to pay principal and interest. Issues determined to possess
              very strong characteristics are a plus (+) designation.
 
    SP-2      Satisfactory capacity to pay principal and interest, with some vulnerability to
              adverse financial and economic changes over the term of the notes.
 
    SP-3      Speculative capacity to pay principal and interest.
</TABLE>
 
     3.  COMMERCIAL PAPER
 
          A S&P commercial paper rating is a current assessment of the
     likelihood of timely payment of debt considered short-term in the relevant
     market. Ratings are graded into several categories, ranging from 'A-1' for
     the highest-quality obligations to 'D' for the lowest. These categories are
     as follows:
 
<TABLE>
    <S>       <C>
    A-1       This highest category indicates that the degree of safety regarding timely
              payment is strong. Those issues determined to possess extremely strong safety
              characteristics are denoted with a plus sign (+) designation.
 
    A-2       Capacity for timely payment on issues with this designation is satisfactory.
              However, the relative degree of safety is not as high as for issues designated
              'A-1'.
 
    A-3       Issues carrying this designation have adequate capacity for timely payment.
              They are, however, more vulnerable to the adverse effects of changes in
              circumstances than obligations carrying the higher designations.
 
    B         Issues rated 'B' are regarded as having only speculative capacity for timely
              payment.
 
    C         This rating is assigned to short-term debt obligations with a doubtful capacity
              for payment.
 
    D         Debt rated 'D' is in payment default. The 'D' rating category is used when
              interest payments or principal payments are not made on the date due, even if
              the applicable grace period has not expired, unless S&P believes that such
              payments will be made during such grace period.

     A commercial paper rating is not a recommendation to purchase or sell a
     security. The ratings are based on current information furnished to S&P by
     the issuer or obtained by S&P from other sources it considers reliable. The
     ratings may be changed, suspended, or withdrawn as a result of changes in
     or unavailability of, such information.
 
     4.  TAX-EXEMPT DUAL RATINGS
 
          S&P assigns "dual" ratings to all debt issues that have a put option
     or demand feature as part of their structure. The first rating addresses
     the likelihood of repayment of principal and interest as due, and the
     second rating addresses only the demand feature. The long-term debt rating
     symbols are used for bonds to denote the long-term maturity and the
     commercial paper rating symbols for the put option (for example,
     'AAA/A-1+'). With short-term demand debt, S&P's note rating symbols are
     used with the commercial paper rating symbols (for example, 'SP-1+/A-1+').
 
  MOODY'S INVESTORS SERVICE--A brief description of the applicable Moody's
Investors Service ("Moody's") rating symbols and their meanings (as published by
Moody's) follows:
 
     1.  LONG-TERM MUNICIPAL BONDS
 
<TABLE>
    <S>       <C>
    AAA       Bonds which are rated Aaa are judged to be of the best quality. They carry the
              smallest degree of investment risk and are generally referred to as "gilt
              edged." Interest payments are protected by a large or by an exceptionally
              stable margin and principal is secure. While the various protective elements
              are likely to change, such changes as can be visualized are most unlikely to
              impair the fundamentally strong position of such issues.
 
    AA        Bonds which are rated Aa are judged to be of high quality by all standards.
              Together with the Aaa group they comprise what are generally known as high
              grade bonds. They are rated lower than the best bonds because margins of
              protection may not be as large as in Aaa securities or fluctuation of
              protective elements may be of greater amplitude or there may be other elements
              present which make the long-term risk appear somewhat larger than the Aaa
              securities.
 
    A         Bonds which are rated A possess many favorable investment attributes and are to
              be considered as upper-medium-grade obligations. Factors giving security to
              principal and interest are considered adequate, but elements may be present
              which suggest a susceptibility to impairment some time in the future.
 
    BAA       Bonds which are rated Baa are considered as medium-grade obligations, (i.e.,
              they are neither highly protected nor poorly secured). Interest payments and
              principal security appear adequate for the present but certain protective
              elements may be lacking or may be characteristically unreliable over any great
              length of time. Such bonds lack outstanding investment characteristics and in
              fact have speculative characteristics as well.
 
    BA        Bonds which are rated Ba are judged to have speculative elements; their future
              cannot be considered as well-assured. Often the protection of interest and
              principal payments may be very moderate, and thereby not well safeguarded
              during both good and bad times over the future. Uncertainty of position
              characterizes bonds in this class.
 
    B         Bonds which are rated B generally lack characteristics of the desirable
              investment. Assurance of interest and principal payments or of maintenance of
              other terms of the contract over any long period of time may be small.
 
    CAA       Bonds which are rated Caa are of poor standing. Such issues may be in default
              or there may be present elements of danger with respect to principal or
              interest.
 
    CA        Bonds which are rated Ca represent obligations which are speculative in a high
              degree. Such issues are often in default or have other marked shortcomings.
 
    C         Bonds which are rated C are the lowest rated class of bonds, and issues so
              rated can be regarded as having extremely poor prospects of ever attaining any
              real investment standing.

<PAGE>   148
 
<TABLE>
    <S>       <C>
    CON (..)  Bonds for which the security depends upon the completion of some act or the
              fulfillment of some condition are rated conditionally and designated with the
              prefix "Con" followed by the rating in parentheses. These are bonds secured by:
              (a) earnings of projects under construction, (b) earnings of projects
              unseasoned in operating experience, (c) rentals that begin when facilities are
              completed, or (d) payments to which some other limiting condition attaches the
              parenthetical rating denotes the probable credit stature upon completion of
              construction or elimination of the basis of the condition.
 
    NOTE:     Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
              classification from AA to B. The modifier 1 indicates that the company ranks in
              the higher end of its generic rating category; the modifier 2 indicates a
              mid-range ranking; and the modifier 3 indicates that the company ranks in the
              lower end of its generic rating category.
</TABLE>
 
     2.  SHORT-TERM EXEMPT NOTES
 
          Moody's ratings for state and municipal short-term obligations will be
     designated Moody's Investment Grade or (MIG). Such ratings recognize the
     differences between short-term credit risk and long-term risk. Factors
     affecting the liquidity of the borrower and short-term cyclical elements
     are critical in short-term ratings, while other factors of major importance
     in bond risk, long-term secular trends for example, may be less important
     over the short run. A short-term rating may also be assigned on an issue
     having a demand feature-variable rate demand obligation. Such ratings will
     be designated as VMIG, SG or, if the demand feature is not rated, as NR.
 
          Moody's short-term ratings are designated Moody's Investment Grade as
     MIG 1 or VMIG 1 through MIG 4 or VMIG 4. As the name implies, when Moody's
     assigns a MIG or VMIG rating, all categories define an investment grade
     situation.
 
          MIG 1/VMIG 1. This designation denotes best quality. There is present
     strong protection by established cash flows, superior liquidity support or
     demonstrated broad-based access to the market for refinancing.
 
          MIG 2/VMIG 2. This designation denotes high quality. Margins of
     protection are ample although not so large as in the preceding group.
 
          MIG 3/VMIG 3. This designation denotes favorable quality. All security
     elements are accounted for but there is lacking the undeniable strength of
     the preceding grades. Liquidity and cash flow protection may be narrow and
     market access for refinancing is likely to be less well established.
 
          MIG 4/VMIG 4. This designation denotes adequate quality. Protection
     commonly regarded as required of an investment security is present and
     although not distinctly or predominantly speculative, there is specific
     risk.
 
          SG. This designation denotes speculative quality. Debt instruments in
     this category lack margins of protection.
 
     3.  TAX-EXEMPT COMMERCIAL PAPER
 
          Moody's short-term debt ratings are opinions of the ability of issuers
     to repay punctually senior debt obligations which have an original maturity
     not exceeding one year. Obligations relying upon support mechanisms such as
     letters-of-credit and bond of Indemnity are excluded unless explicitly
     rated.
 
          Moody's employs the following three designations, all judged to be
     investment grade, to indicate the relative repayment ability of rated
     issuers:
 
             Issuers rated Prime-1 (or supporting institutions) have a superior
        ability for repayment of senior short-term debt obligations.
 
             Issuers rated Prime-2 (or supporting institutions) have a strong
        ability for repayment of senior short-term debt obligations.
 
                                      B-17
<PAGE>   149
 
             Issuers rated Prime-3 (or supporting institutions) have an
        acceptable ability for repayment of senior short-term debt obligations.
 
          Issuers rated Not Prime do not fall within any of the Prime rating
     categories.

after giving effect to the exercise of such options, no officer or trustee of
the Fund owns or would own 5% or more of the common stock of VK/AC Holding, Inc.
 
  The investment advisory agreement provides that the Adviser will supply

securities for the Fund to purchase. The Adviser also administers the business
affairs of the Fund, furnishes offices, necessary facilities and equipment,
provides administrative services, and permits its officers and employees to
serve without compensation as officers of the Fund and trustees of the Trust if

  The agreement provides that the Adviser shall not be liable for any error of
judgment or of law, or for any loss suffered by the Fund in connection with the
matters to which the agreement relates, except a loss resulting from willful
misfeasance, bad faith, or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under the agreement.
 
  The Adviser's activities are subject to the review and supervision of the
Board of Trustees of the Trust, of which the Fund is a series, to whom the
Adviser renders periodic reports of the Fund's investment activities.

year to year if specifically approved by the Trustees of the Trust, of which the
Fund is a separate series (or by the Fund's shareholders), and by the
disinterested trustees in compliance with the requirements of the 1940 Act. The
agreement may be terminated without penalty upon 60 days' written notice by
either party thereto and will automatically terminate in the event of
assignment.

  The investment advisory agreement specifies that the Adviser will reimburse
the Fund for annual expenses of the Fund which exceed the most stringent limit
prescribed by any state in which the Fund's shares are offered for sale.
Currently, the most stringent limit in any state would require such
reimbursement to the extent that aggregate operating expenses of the Fund
(excluding interest, taxes and other expenses which may be excludable under
applicable state law) exceed in any fiscal year 2 1/2% of the average annual net
assets of the Fund up to $30 million, 2% of the average annual net assets of the
Fund of the next $70 million, and 1 1/2% of the remaining average annual net
assets of the Fund. In addition to making any required reimbursements, the
Adviser may in its discretion, but is not obligated to, waive all or any portion
of its fee or assume all or any portion of the expenses of the Fund.
 
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
advisory expenses of $3,475,616, $2,578,871 and $1,315,431, respectively.
 
OTHER AGREEMENTS
 
  SUPPORT SERVICES AGREEMENT.  Under a support services agreement with the
Distributor which terminated as of July 10, 1995 concurrent with the Fund's
change in transfer agent, the Fund received support services for shareholders,
including the handling of all written and telephonic communications, except
initial order entry and other distribution related communications. Payment by
the Fund for such services was made on cost basis for the employment of the
personnel and the equipment necessary to render the support services. At such
time, the Fund, and the other Van Kampen American Capital mutual funds
distributed by the Distributor, shared such costs proportionately among
themselves based upon their respective net asset values.
 
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $334,800, $275,030 and $158,860, respectively,
representing the Distributor's cost of providing certain support services.
 
  ACCOUNTING SERVICES AGREEMENT.  The Fund has entered into an accounting
services agreement pursuant to which the VK Adviser provides accounting services
supplementary to those provided by the Custodian. Such services are expected to
enable the Fund to more closely monitor and maintain its accounts and records.
The Fund shares together with the other Van Kampen American Capital mutual funds
advised by the VK Adviser and distributed by the Distributor in the cost of
providing such services, with 25% of such costs shared proportionately based on
the number of outstanding classes of securities per fund and with the remaining
75 percent of such cost being paid by the Fund and such other Van Kampen
American Capital funds based proportionally on their respective net assets.
 
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $18,250, $16,306 and $7,960, respectively,
representing the VK Adviser's cost of providing accounting services.
 
  LEGAL SERVICES AGREEMENT.  The Fund and each of the other Van Kampen American
Capital funds advised by the VK Adviser and distributed by the Distributor have
entered into Legal Services Agreements pursuant to which Van Kampen American
Capital provides legal services, including without limitation: accurate
maintenance of the funds' minute books and records, preparation and oversight of
the funds' regulatory reports, and other information provided to shareholders,
as well as responding to day-to-day legal issues on behalf of the funds. Payment
by the Fund for such services is made on a cost basis for the salary and salary
related benefits, including but not limited to bonuses, group insurances and
other regular wages for the employment of personnel, as well as overhead and the
expenses related to the office space and the equipment necessary to render the
legal services. Other funds distributed by the Distributor also receive legal
services from Van Kampen American Capital. Of the total costs for legal services
provided to funds distributed by the Distributor, one half of such costs are
allocated equally to each fund and the remaining one half of such costs are
allocated to specific funds based on monthly time records.
 
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $21,950, $21,500 and $7,200, respectively,
representing Van Kampen American Capital's cost of providing legal services.

CUSTODIAN AND INDEPENDENT AUDITORS
 
  State Street Bank and Trust Company, 225 Franklin Street, P.O. Box 1713,
Boston, MA 02105-1713, is the custodian of the Fund and has custody of all
securities and cash of the Fund. The custodian, among other things, attends to
the collection of principal and income, and payment for and collection of
proceeds of securities bought and sold by the Fund.
 
  The independent auditors for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent auditors will be subject to ratification
by the shareholders of the Fund at any annual meeting of shareholders.
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION
 
  The Adviser will place orders for portfolio transactions for the Fund with
broker-dealer firms giving consideration to the quality, quantity and nature of
each firm's professional services. These services include execution, clearance
procedures, wire service quotations and statistical and other research
information provided to the Fund, or the Adviser, including quotations necessary
to determine the value of the Fund's net assets. Any research benefits derived
are available for all clients of the Adviser. Since statistical and other
research information is only supplementary to the research efforts of the
Adviser to the Fund and still must be analyzed and reviewed by its staff, the
receipt of research information is not expected to materially reduce its
expenses.
 
  If it is believed to be in the best interests of the Fund, the Adviser may
place portfolio transactions with brokers who provide the types of research
described above, even if it means the Fund will have to pay a higher commission
(or, if the broker's profit is part of the cost of the security, will have to
pay a higher price for the security), than would be the case if no weight were
given to the broker's furnishing of those research services. This will be done,
however, only if, in the opinion of the Fund's Adviser, the amount of additional
commission or increased cost is reasonable in relation to the value of such
services.
 
  In selecting among the firms believed to meet the criteria for handling a
particular transaction, the Adviser may take into consideration that certain
firms (i) provide market, statistical or other research information such as that
set forth above to the Fund or the Adviser, (ii) have sold or are selling shares
of the Fund and (iii) may select firms that are affiliated with the Fund, the
Adviser, or its distributor and other principal underwriters.
 
  If purchases or sales of securities of the Fund and of one or more other
investment companies or clients supervised by the Adviser are considered at or
about the same time, transactions in such securities will be allocated among the
several investment companies and clients in a manner deemed equitable to all by
the Adviser, taking into account the respective sizes of the Fund and other
investment companies and clients and the amount of securities to be purchased or
sold. Although it is possible that in some cases this procedure could have a
detrimental effect on the price or volume of the security as far as the Fund is
concerned, it is also possible that the ability to participate in volume
transactions and to negotiate lower brokerage commissions will be beneficial to
the Fund.
 
  While the Adviser will be primarily responsible for the placement of the
Fund's business, the policies and practices in this regard must be consistent
with the foregoing and will at all times be subject to review by the trustees of
the Trust, of which the Fund is a separate series.
 
  The trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the SEC under the 1940 Act which requires that the commissions
paid to the Distributor and other affiliates of the Fund must be reasonable and
fair compared to the commissions, fees or other remuneration received or to be
received by other brokers in connection with comparable transactions involving
similar securities during a comparable period of time. The rule and procedures
also contain review requirements and require the Adviser to furnish reports to
the trustees and to maintain records in connection with such reviews. After
consideration of all factors deemed relevant, the trustees will consider from
time to time whether the advisory fee for the Fund will be reduced by all or a
portion of the brokerage commission given to affiliated brokers.

  State securities laws may differ from the interpretations of federal law
expressed herein, and banks and financial institutions may be required to
register as dealers pursuant to state law.
 
                             TAX STATUS OF THE FUND
 
  The Trust and each of its series, including the Fund, will be treated as
separate corporations for income tax purposes. The Fund may be subject to tax if
it fails to distribute net capital gains, or if its annual distributions, as a
percentage of its income, are less than the distributions required by tax laws.
 
                                THE DISTRIBUTOR
 
  The Distributor offers one of the industry's broadest lines of investments --
encompassing mutual funds, closed-end funds and unit investment trusts -- and is
currently the nation's 5th largest broker-sold mutual fund group according to
Strategic Insight. Van Kampen American Capital's roots in money management
extend back to 1926. Today, Van Kampen American Capital manages or supervises
more than $50 billion in mutual funds, closed-end funds and unit investment
trusts -- assets which have been entrusted to Van Kampen American Capital in
more than 2 million investor accounts. Van Kampen American Capital has one of
the largest research teams (outside of the rating agencies) in the country, with
86 analysts devoted to various specializations.
 
  Shares of the Fund are offered on a continuous basis through the Distributor,
One Parkview Plaza, Oakbrook Terrace, IL 60181. The Distributor is a wholly
owned subsidiary of Van Kampen American Capital, Inc., which is a subsidiary of
VK/AC Holding, Inc., a Delaware corporation that is controlled through an
ownership of a substantial majority of its common stock, by The Clayton &
Dubilier Private Equity Fund IV Limited Partnership ("C & D L.P."), a
Connecticut limited partnership. In addition, certain officers, directors and
employees of Van Kampen American Capital, Inc., and its subsidiaries own, in the
aggregate not more than 7% of the common stock of VK/AC Holding, Inc. and have
the right to acquire, upon the exercise of options, approximately an additional
11% of the common stock of VK/AC Holding, Inc. C & D L.P. is managed by Clayton,
Dubilier & Rice, Inc. Clayton & Dubilier Associates IV Limited Partnership ("C &
D Associates L.P.") is the general partner of C & D L.P. Pursuant to a
distribution agreement, the Distributor will purchase shares of the Fund for
resale to the public, either directly or through securities dealers, and is
obligated to purchase only those shares for which it has received purchase
orders. A discussion of how to purchase and redeem the Fund's shares and how the
Fund's shares are priced is contained in the Prospectus.
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of shares. The Distribution Plan and Service Plan sometimes are
referred to herein collectively as the "Plans". The Plans provide that the Fund
may spend a portion of the Fund's average daily net assets attributable to each
class of shares in connection with distribution of the respective class of
shares and in connection with the provision of ongoing services to shareholders
of such class, respectively. The Plans are being implemented through an
agreement (the "Distribution and Service Agreement") with the Distributor,
distributor of each class of the Fund's shares, sub-agreements between the
Distributor and members of the NASD who are acting as securities dealers and
NASD members or eligible non-members who are acting as brokers or agents and
similar agreements between the Fund and financial intermediaries who are acting
as brokers (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance, which may include, but not
be limited to, processing purchase and redemption transactions, establishing and
maintaining shareholder accounts regarding the Fund, and such other services as
may be agreed to from time to time and as may be permitted by applicable
statute, rule or regulation. Brokers, dealers and financial intermediaries that
have entered into sub-agreements with the Distributor and sell shares of the
Fund are referred to herein as "financial intermediaries."
 
  Under the Distribution and Service Agreement and the Selling Agreements,
financial intermediaries that sold shares prior to July 1, 1987, or prior to the
beginning of the calendar quarter in which the Selling Agreement between the
Fund and such financial intermediary was approved by the Fund's Board of
Trustees (an "Implementation Date") are not eligible to receive compensation
pursuant to such Distribution and Service Agreement and/or Selling Agreement. To
the extent that there remain outstanding shares of the Fund
 
                                      B-26
<PAGE>   158
 
that were purchased prior to all Implementation Dates, the percentage of the
total average daily net asset value of a class of shares that may be utilized
pursuant to the Distribution and Service Agreement will be less than the maximum
percentage amount permissible with respect to such class of shares under the
Distribution and Service Agreement.
 
  The Distributor must submit quarterly reports to the Board of Trustees of the
Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Plans and the purposes for which such
expenditures were made, together with such other information as from time to
time is reasonably requested by the Trustees. The Plans provide that they will
continue in full force and effect from year to year so long as such continuance
is specifically approved by a vote of the Trustees, and also by a vote of the
disinterested Trustees, cast in person at a meeting called for the purpose of
voting on the Plans. Each of the Plans may not be amended to increase materially
the amount to be spent for the services described therein with respect to either
class of shares without approval by a vote of a majority of the outstanding
voting shares of such class, and all material amendments to either of the Plans
must be approved by the Trustees and also by the disinterested Trustees. Each of
the Plans may be terminated with respect to either class of shares at any time
by a vote of a majority of the disinterested Trustees or by a vote of a majority
of the outstanding voting shares of such class.
 
  For the year ended December 31, 1994, the Fund has recognized expenses under
the Plans of $1,626,311, $1,662,702 and $41,554 for the Class A Shares, Class B
Shares and Class C Shares, respectively, of which $1,357,846 and $408,661
represent payments to financial intermediaries under the Selling Agreements for
Class A Shares and Class B Shares, respectively. For the year ended December 31,
1994, the Fund has reimbursed the Distributor $212,577 and $55,751 for
advertising expenses, and $40,262 and $26,873 for compensation of the
Distributor's sales personnel for the Class A Shares and Class B Shares,
respectively.

  Counsel to the Fund is Skadden, Arps, Slate, Meagher & Flom, Chicago,
Illinois.
 
                            PERFORMANCE INFORMATION
 
  The Fund's yield quotation is determined on a monthly basis with respect to
the immediately preceding 30 day period, and yield is computed by dividing the
Fund's net investment income per share of a given class earned during such
period by the Fund's maximum offering price (including, with respect to the
Class A Shares, the maximum initial sales charge) per share of such class on the
last day of such period. The Fund's net investment income per share is
determined by taking the interest attributable to a given class of shares earned
by the Fund during the period, subtracting the expenses attributable to a given
class of shares accrued for the period (net of any reimbursements), and dividing
the result by the average daily number of the shares of each class outstanding
during the period that were entitled to receive dividends. The yield calculation
formula assumes net investment income is earned and reinvested at a constant
rate and annualized at the end of a six month period. Yield will be computed
separately for each class of shares. Class B Shares redeemed during the first
six years after their issuance and Class C Shares redeemed during the first year
after their issuance may be subject to a contingent deferred sales charge in a
maximum amount equal to 4% and 1%, respectively, of the lesser of the then
current net asset value of the shares redeemed or their initial purchase price
from the Fund. Yield quotations do not reflect the imposition of a contingent
deferred sales charge, and if any such contingent deferred sales charge imposed
at the time of redemption were reflected, it would reduce the performance
quoted.
 
  Tax-equivalent yield demonstrates the taxable yield required to produce an
after-tax yield equivalent to that of the Fund's yield. The Fund's
tax-equivalent yield quotation for a 30 day period as described above is
computed by dividing that portion of the yield of the Fund (as computed above)
which is tax-exempt by a percentage equal to 100% minus a stated percentage
income tax rate and adding the result to that portion of the Fund's yield, if
any, that is not tax-exempt.
 
  The Fund calculates average compounded total return by determining the
redemption value (less any applicable contingent deferred sales charge) at the
end of specified periods (after adding back all dividends
 
                                      B-27
<PAGE>   159
 
and other distributions made during the period) of a $1,000 investment in a
given class of shares of the Fund (less the maximum sales charge, if any) at the
beginning of the period, annualizing the increase or decrease over the specified
period with respect to such initial investment and expressing the result as a
percentage. Average compounded total return will be computed separately for each
class of shares.
 
  Total return figures utilized by the Fund are based on historical performance
and are not intended to indicate future performance. Total return and net asset
value per share of a given class can be expected to fluctuate over time, and
accordingly upon redemption a shareholder's shares may be worth more or less
than their original cost.
 
  The Fund may, in supplemental sales literature, advertise non-standardized
total return figures representing the cumulative, non-annualized total return of
each class of shares of the Fund from a given date to a subsequent given date.
Cumulative total return is calculated by measuring the value of an initial
investment in a given class of shares of the Fund at a given time, including or
excluding any applicable sales charge as indicated, determining the value of all
subsequent reinvested distributions, and dividing the net change in the value of
the investment as of the end of the period by the amount of the initial
investment and expressing the result as a percentage. Non-standardized total
return will be calculated separately for each class of shares. Non-standardized
total return calculations do not reflect the imposition of a contingent deferred
sales charge, and if any such contingent deferred sales charge with respect to
the CDSC imposed at the time of redemption were reflected, it would reduce the
performance quoted.

  The average total return, including payment of maximum sales charge, with
respect to the Class A Shares for (i) the one year period ended December 31,

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

of operations for the year then ended, the statement of changes in
net assets for each of the two years in the period then ended, and the
financial highlights for each of the periods presented. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with generally accepted
auditing standards. Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether the financial state-
ments and financial highlights are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of December 31, 1994, by correspondence with
the custodian. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Van
Kampen Merritt Municipal Income Fund as of December 31, 1994, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of

Van Kampen Merritt Municipal Income Fund

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

1. Significant Accounting Policies

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

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


A. Security Valuation-Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost.


B. Security Transactions-Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" and "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain in a segregated account with its custodian assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made. At December 31, 1994, there were no
when issued or delayed delivery purchase commitments.


C. Investment Income-Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of
each applicable security.

D. Organizational Expenses and Initial Registration Costs-The Fund has
reimbursed Van Kampen American Capital Distributors, Inc. or its affiliates
("VKAC") for costs incurred in connection with the Fund's organization and
initial registration in the amount of $152,425. These costs are being amortized
on a straight line basis over the 60 month period ending July 31, 1995. Van
Kampen American Capital Investment Advisory Corp. (the "Adviser") has agreed
that in the event any of the initial shares of the Fund originally purchased
by VKAC are redeemed during the amortization period, the Fund will be
reimbursed for any unamortized organizational expenses and initial
registration costs in the same proportion as the number of shares redeemed
bears to the number of initial shares held at the time of redemption.


E. Federal Income Taxes-It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and
to distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At December 31, 1994, the Fund had an accumulated capital loss
carryforward for tax purposes of $18,151,198. Of this amount, $10,452,715 and
$7,698,483 will expire on December 31, 2001 and 2002, respectively. Net realized
gains or losses may differ for financial and tax reporting purposes primarily as
a result of the deferral of post October 31 losses and the capitalization of
reorganization and restructuring costs for tax purposes.


F. Distribution of Income and Gains-The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes. Due to inherent differences in the recognition of interest income
under generally accepted accounting principles and federal income tax purposes,
for those securities which the Fund has placed on non-accrual status, the amount
of distributable net investment income may differ between book and federal
income tax purposes for a particular period. These differences are temporary in

nature, but may result in book basis distribution in excess of net investment
income for certain periods.


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

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

</TABLE>


Certain legal expenses are paid to Skadden, Arps, Slate, Meagher & Flom, counsel
to the Fund, of which a trustee of the Fund is an affiliated person.

For the year ended December 31, 1994, the Fund recognized expenses of
approximately $375,000 representing VKAC's cost of providing accounting, legal
and certain shareholder services to the Fund.

Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC.

4. Investment Transactions

notes and reorganization and restructuring costs, for the year ended December

5. Derivative Financial Instruments

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

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

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


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

</TABLE>



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

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

Transactions in futures contracts for the year ended December 31, 1994, were as
follows:

C. Indexed Securities-These instruments are identified in the portfolio of
investments. The price of these securities may be more volatile than the price
of a comparable fixed rate security.

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

An Embedded Swap security includes a swap component such that the fixed coupon
component of the underlying bond is adjusted by the difference between the
securities fixed swap rate and the floating swap index. As the floating rate
rises, the coupon is reduced. Conversely, as the floating rate declines, the
coupon is increased. These instruments are typically used by the Fund to
enhance the yield of the portfolio.

6. Distribution and Service Plans

The Fund and its shareholders have adopted a distribution plan (the
"Distribution Plan") pursuant to Rule 12b-1 under the Investment Company Act of

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>   182
 
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>   183
 
        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
 
                                        4

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>   185
 
     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>   186
 
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>   188
 
     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.

    $2,000; Sheehan, $2,000; Sisto, $2,000; Woodside, $1,000 (Mr. Woodside was
    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.
 
INVESTMENT ADVISORY AGREEMENT
 
     The Fund and the Adviser are parties to an investment advisory agreement
(the "Advisory Agreement"). Under the Advisory Agreement, the Fund retains the
Adviser to manage the investment of its assets and to place orders for the
purchase and sale of its portfolio securities. The Adviser is responsible for
obtaining and evaluating economic, statistical, and financial data and for
formulating and implementing investment programs in furtherance of the Fund's
investment objective. The Adviser also furnishes at no cost to the Fund (except
as noted herein) the services of sufficient executive and clerical personnel for
the Fund as are necessary to prepare registration statements, prospectuses,
shareholder reports and notices, and proxy
 
                                       13
<PAGE>   193
 
solicitation materials. In addition, the Adviser furnishes at no cost to the
Fund the services of a President of the Fund, one or more Vice Presidents as
needed, and a Secretary.
 
     Under the Advisory Agreement, the Fund bears the cost of its accounting
services, which includes maintaining its financial books and records and
calculating its daily net asset value. The costs of such accounting services
include the salaries and overhead expenses of a Treasurer or other principal
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>   194
 
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>   195
 
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>   196
 
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>   197
 
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>   198
 
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>   199
 
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>   200
 
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
<PAGE>   201
 
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>   202
 
     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>   203
 
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>   204
 
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>   205
 
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>   208
 
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>   209
 
     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>   225

      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>   226
$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.

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.

                                  (Unaudited)
- -------------------------------------------------------------------------------
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
 
                                      F-38

- -------------------------------------------------------------------------------
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.

AMERICAN CAPITAL MUNICIPAL BOND FUND, INC.
 
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
 
                                      C-18
<PAGE>   270
 
AMERICAN CAPITAL MUNICIPAL BOND FUND, INC.
 
   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 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.
 
                                      C-19
<PAGE>   271
 
AMERICAN CAPITAL MUNICIPAL BOND FUND, INC.
 
     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 $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

(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.
(4) Total return does not consider the effect of sales charges.

    per share. At September 30, 1992, there were 50 Class B shares outstanding

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) 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.
(4) Total return for a period of less than one full year is not annualized.
    Total return does not consider the effect of sales charges.

    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

AMERICAN CAPITAL MUNICIPAL BOND FUND, INC.
 
NOTES TO FINANCIAL STATEMENTS
(Unaudited)
 
NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES
 
     American Capital Municipal Bond Fund, Inc. (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 March 31, 1995, debt securities rated below investment
grade and comparable unrated securities represented approximately 20% 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 of 1986, as amended (the "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.
 
     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
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 require-

NOTES TO FINANCIAL STATEMENTS -- CONTINUED
(Unaudited)
 
ments of the 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
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
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
 
     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
allocated 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 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 period ended March 31, 1995, the fees for such
services were $147,187.
 
     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 $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
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 March 31, 1995, the unreimbursed expenses incurred
by the Distributor under the Class B and Class C plans aggregated approximately
 
                                      D-23

$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 renewal 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 Trustee 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
investments, excluding short-term investments, were $8,215,930 and $12,451,313,
respectively.
 
     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 aggregated
$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
Committee 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 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.

VAN KAMPEN MERRITT MUNICIPAL INCOME FUND
 
NOTES TO FINANCIAL STATEMENTS
December 31, 1994
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
     Van Kampen Merritt Municipal Income Fund (the "Fund") was organized as a
sub-trust of the Van Kampen Merritt Tax Free Fund, a Massachusetts business
trust, and is registered as a diversified open-end management investment company
under the Investment Company Act of 1940, as amended. The Fund commenced
investment operations on August 1, 1990. On August 24, 1992, the Fund commenced
the distribution of its Class B shares. The distribution of the Fund's Class C
shares, which were initially introduced as Class D shares and subsequently
renamed Class C shares on March 7, 1994, commenced on August 13, 1993. The
distribution of the Fund's fourth class of shares, Class D shares, commenced on
March 14, 1994.
 
     The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements.
 
     A. Security Valuation -- Investments are stated at value using market
quotations or, if such valuations are not available, estimates obtained from
yield data relating to instruments or securities with similar characteristics in
accordance with procedures established in good faith by the Board of Trustees.
Short-term securities with remaining maturities of less than 60 days are valued
at amortized cost.
 
     B. Security Transactions -- Security transactions are recorded on a trade
date basis. Realized gains and losses are determined on an identified cost
basis. The Fund may purchase and sell securities on a "when issued" and "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Fund will maintain in a segregated account with its custodian assets having an
aggregate value at least equal to the amount of the when issued or delayed
delivery purchase commitments until payment is made. At December 31, 1994, there
were no when issued or delayed delivery purchase commitments.
 
     C. Investment Income -- Interest income is recorded on an accrual basis.
Bond premium and original issue discount are amortized over the expected life of
each applicable security.
 
     D. Organizational Expenses and Initial Registration Costs -- The Fund has
reimbursed Van Kampen American Capital Distributors, Inc. or its affiliates
("VKAC") for costs incurred in connection with the Fund's organization and
initial registration in the amount of $152,425. These costs are being amortized
on a straight line basis over the 60 month period ending July 31, 1995. Van
Kampen American Capital Investment Advisory Corp. (the "Adviser") has agreed
that in the event any of the initial shares of the Fund originally purchased by
VKAC are redeemed during the amortization period, the Fund will be reimbursed
for any unamortized organizational expenses and initial registration costs in
the same proportion as the number of shares redeemed bears to the number of
initial shares held at the time of redemption.
 
     E. Federal Income Taxes -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no provision for federal income taxes is required.
 
     The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future

realized capital gains. At December 31, 1994, the Fund had an accumulated
capital loss carryforward for tax purposes of $18,151,198. Of this amount,
$10,452,715 and $7,698,483 will expire on December 31, 2001 and 2002,
respectively. Net realized gains or losses may differ for financial and tax
reporting purposes primarily as a result of the deferral of post October 31
losses and the capitalization of reorganization and restructuring costs for tax
purposes.
 
     F. Distribution of Income and Gains -- The Fund declares daily and pays
monthly dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes. Due to inherent differences in the recognition of interest income
under generally accepted accounting principles and federal income tax purposes,
for those securities which the Fund has placed on non-accrual status, the amount
of distributable net investment income may differ between book and federal
income tax purposes for a particular period. These differences are temporary in
nature, but may result in book basis distribution in excess of net investment
income for certain periods.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
 
     Under the terms of the Fund's Investment Advisory Agreement, the Adviser
will provide investment advice and facilities to the Fund for an annual fee
payable monthly as follows:

     Certain legal expenses are paid to Skadden, Arps, Slate, Meagher & Flom,
counsel to the Fund, of which a trustee of the Fund is an affiliated person.
 
     For the year ended December 31, 1994, the Fund recognized expenses of
approximately $375,000 representing VKAC's cost of providing accounting, legal
and certain shareholder services to the Fund.
 
     Certain officers and trustees of the Fund are also officers and directors
of VKAC. The Fund does not compensate its officers or trustees who are officers
of VKAC.
 
     The Fund has implemented deferred compensation and retirement plans for its
Trustees. Under the deferred compensation plan, Trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those Trustees who are not officers of VKAC.
 
     At December 31, 1994, VKAC owned 387, 105, 100 and 100 shares of Classes A,
B, C and D, respectively.
 
3. CAPITAL TRANSACTIONS
 
     The Fund has outstanding four classes of common shares, Classes A, B, C and
D. There are an unlimited number of shares of each class without par value
authorized.

VAN KAMPEN MERRITT MUNICIPAL INCOME FUND
 
NOTES TO FINANCIAL STATEMENTS -- CONTINUED
December 31, 1994
 
     For the year ended December 31, 1994, VKAC, as Distributor for the Fund,
received net commissions on sales of the Fund's Class A shares of approximately
$209,000 and CDSC on the redeemed shares of Classes B, C and D of approximately
$516,000. Sales charges do not represent expenses of the Fund.
 
4. INVESTMENT TRANSACTIONS
 
     Aggregate purchases and sales of investment securities, excluding
short-term notes and reorganization and restructuring costs, for the year ended
December 31, 1994, were $541,728,813 and $708,214,680, respectively.
 
5. DERIVATIVE FINANCIAL INSTRUMENTS
 
     A derivative financial instrument in very general terms refers to a
security whose value is "derived" from the value of an underlying asset,
reference rate or index.
 
     The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective yield, maturity and duration.
All of the Fund's portfolio holdings, including derivative instruments, are
marked to market each day with the change in value reflected in the unrealized
appreciation/depreciation on investments. Upon disposition, a realized gain or
loss is recognized accordingly, except for exercised option contracts where the
recognition of gain or loss is postponed until the disposal of the security
underlying the option contract.
 
     Summarized below are the specific types of derivative financial instruments
used by the Fund.
 
     A. Option Contracts -- An option contract gives the buyer the right, but
not the obligation to buy (call) or sell (put) an underlying item at a fixed
exercise price during a specified period. These contracts are generally used by
the Fund to manage the portfolio's effective maturity and duration.
 
     Transactions in options for the year ended December 31, 1994, were as
follows:

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

     C. Indexed Securities -- These instruments are identified in the portfolio
of investments. The price of these securities may be more volatile than the
price of a comparable fixed rate security.
 
     An Inverse Floating security is one where the coupon is inversely indexed
to a short-term floating interest rate multiplied by a specified factor. As the
floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. These instruments are typically used by the
Fund to enhance the yield of the portfolio.
 
     An Embedded Swap security includes a swap component such that the fixed
coupon component of the underlying bond is adjusted by the difference between
the securities fixed swap rate and the floating swap

6. DISTRIBUTION AND SERVICE PLANS
 
     The Fund and its shareholders have adopted a distribution plan (the
"Distribution Plan") pursuant to Rule 12b-1 under the Investment Company Act of
1940 and a service plan (the "Service Plan," collectively the "Plans"). The
Plans govern payments for the distribution of the Fund's shares, ongoing
shareholder services and maintenance of shareholder accounts.
 
     Annual fees under the Plans of up to .30% each for Class A and Class D
shares and 1.00% each for Class B and Class C shares are accrued daily. Included
in these fees for the year ended December 31, 1994, are payments to VKAC of
approximately $1,540,000.

THE BOARD OF TRUSTEES AND SHAREHOLDERS OF
VAN KAMPEN MERRITT MUNICIPAL INCOME FUND:
 
     We have audited the accompanying statement of assets and liabilities of Van

investments, as of December 31, 1994, and the related statement of operations
for the year then ended, the statement of changes in net assets for each of the
two years in the period then ended, and the financial highlights for each of the
periods presented. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1994, by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of Van
Kampen Merritt Municipal Income Fund as of December 31, 1994, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of

DEAR VAN KAMPEN AMERICAN CAPITAL INSURED MUNICIPAL FUND SHAREHOLDER:
 
  Enclosed is information asking you for your vote on a reorganization (the
"Reorganization") pursuant to an Agreement and Plan of Reorganization (the
"Agreement") for the Van Kampen American Capital Insured Municipal Fund (the "AC
Fund"), a series of the Van Kampen American Capital Tax-Exempt Trust
("Tax-Exempt Trust"). The Reorganization calls for the AC Fund shareholders to
become shareholders of the Van Kampen American Capital Insured Tax Free Income
Fund (the "VK Fund"), a mutual fund which pursues a substantially similar
investment objective.
 
  The enclosed materials include a combined Proxy Statement/Prospectus
containing information you need to make an informed decision. However, we
thought it would also be helpful for you to have, at the start, answers to some
of the important questions you might have about the proposed Reorganization. We
hope you find these explanations useful as you review your materials before
voting. For more detailed information about the Reorganization, please refer to
the combined Proxy Statement/Prospectus.
 
HOW WILL THE REORGANIZATION AFFECT ME?
 
  Assuming shareholders of the AC Fund approve the Reorganization, the assets
and liabilities of the AC Fund will be combined with those of the VK Fund and
you will become a shareholder of the VK Fund. You will receive shares of the VK
Fund approximately equal in value at the time of issuance to the shares of the
AC Fund that you hold immediately prior to the Reorganization. See the section
of the combined Proxy Statement/Prospectus entitled "Distribution, Purchase,
Valuation, Redemption and Exchange of Shares." Class A shareholders of the AC
Fund will receive Class A shares of the VK Fund; Class B shareholders of the AC
Fund will receive Class B shares of the VK Fund; and Class C shareholders of the
AC Fund will receive Class C shares of the VK Fund.
 
WHY IS THE REORGANIZATION BEING RECOMMENDED?
 
  As we reported to you earlier, the parent company of Van Kampen American
Capital Asset Management, Inc. ("AC Adviser"), the investment adviser to the AC
Fund, was acquired in December 1994 by Van Kampen American Capital, Inc.
("VKAC"), and was subsequently merged into VKAC. VKAC, through its wholly owned
subsidiaries, distributes and manages the Van Kampen American Capital funds. AC
Adviser is an affiliate of Van Kampen American Capital Investment Advisory Corp.
("VK Adviser"), the investment adviser to the VK Fund. The primary purposes of
the proposed Reorganization are to seek to achieve future economies of scale and
eliminate certain costs associated with operating the AC Fund and the VK Fund
separately. The Reorganization would result in combining
<PAGE>   333
 
the assets and liabilities of the AC Fund with the assets and liabilities of the
VK Fund and consolidating their operations.
 
  The Reorganization is intended to provide various benefits to shareholders of
the AC Fund who become shareholders of the VK Fund (as well as to existing and
future investors in the VK Fund). For example, higher net asset levels should
enable the VK Fund to spread fixed and relatively fixed costs, such as
accounting, legal and printing expenses, over a larger asset base, thereby
potentially reducing per share expense levels. Higher net asset levels also may
benefit portfolio management by permitting larger individual portfolio
investments that may result in reduced transaction costs or more favorable
pricing and by providing the opportunity for greater portfolio diversity. These
benefits, in turn, should have a favorable effect on the relative performance of
the VK Fund.
 
  The consummation of the Reorganization is subject to the satisfaction of a
number of conditions (including approval by the AC Fund's shareholders), which
are summarized below in "The Proposed Reorganization -- Terms of the Agreement"
section of the accompanying combined Proxy Statement/Prospectus. These
conditions are stated in the Agreement which is attached as Exhibit A to the
combined Proxy Statement/Prospectus.
 
WILL I HAVE TO PAY ANY SALES LOAD, COMMISSION OR OTHER TRANSACTIONAL FEE IN
CONNECTION WITH THE REORGANIZATION?
 
  No. The full value of your shares of the AC Fund would be exchanged for shares
of the corresponding class of the VK Fund without any sales load, commission or
other transactional fee being imposed. As more fully discussed in the combined
Proxy Statement/Prospectus, the holding period for shareholders acquiring Class
B or Class C shares in the Reorganization subject to a contingent deferred sales
charge will be measured from the time (i) the holder purchased Class B or C
shares from the AC Fund or (ii) purchased Class B or C shares of any other Van
Kampen American Capital open-end fund and subsequently exchanged into Class B or
C shares of the AC Fund. If the Reorganization is completed, the VK Fund will
bear the costs associated with the Reorganization, such as printing and mailing
costs and other expenses associated with the Special Meeting. If the
Reorganization is not completed VKAC will bear the costs associated with the
Reorganization.
 
HOW WILL THE FEES PAID BY THE VK FUND COMPARE TO THOSE PAYABLE BY THE AC FUND?
 
  It is anticipated that, on a per share basis, the total of the various fees
and expenses incurred by the VK Fund will be less, upon completion of the
Reorganization, than the total of such fees and expenses applicable to the AC
Fund.
<PAGE>   334
 
WHAT WILL I HAVE TO DO TO OPEN AN ACCOUNT IN THE VAN KAMPEN AMERICAN CAPITAL
INSURED TAX FREE INCOME FUND? WHAT HAPPENS TO MY ACCOUNT IF THE REORGANIZATION
IS APPROVED?
 
  If the Reorganization is approved, your interest in Class A, B or C shares,
respectively, of the AC Fund will automatically be converted into the same class
of shares of the VK Fund and we will send you written confirmation that this
change has taken place. You will receive the same class of shares of the VK Fund
approximately equal in value to your Class A, B or C shares of the AC Fund. No
certificates for VK Fund shares will be issued in connection with the
Reorganization, although such certificates will be available upon request. If
you currently hold certificates representing your shares of the AC Fund, it is
not necessary to surrender such certificates.
 
WHO WILL ADVISE THE VK FUND AND PROVIDE OTHER SERVICES?
 
  VK Adviser provides advisory services to the VK Fund under an arrangement that
is substantially similar to that currently in effect between the AC Fund and AC
Adviser. The contractual advisory fees payable by the VK Fund are no higher than
the contractual advisory fees applicable to the AC Fund. Van Kampen American
Capital Distributors, Inc. serves as distributor of the shares of both the VK
Fund and the AC Fund. In addition, State Street Bank & Trust Company, 225
Franklin Street, P.O. Box 1713, Boston, Massachusetts 02105-1713 is the
custodian of both the VK Fund and the AC Fund. ACCESS Investor Services, Inc.,
P.O. Box 418256, Kansas City, Missouri 64141-9256, serves as the transfer agent
for both the VK Fund and the AC Fund.
 
WILL I HAVE TO PAY ANY FEDERAL TAXES AS A RESULT OF THE REORGANIZATION?
 
  The Reorganization is intended to qualify as a "reorganization" within the
meaning of Section 368(a)(1) of the Internal Revenue Code of 1986, as amended
(the "Code"). If the Reorganization so qualifies, in general, a shareholder of
the AC Fund will recognize no gain or loss upon the receipt of solely the Shares
of the VK Fund in connection with the Reorganization. Additionally, the AC Fund
would not recognize any gain or loss as a result of the transfer of all of its
assets and liabilities solely in exchange for the Shares of the VK Fund or as a
result of its liquidation. The VK Fund expects that it will not recognize any
gain or loss as a result of the Reorganization, that it will take a carryover
basis in the assets acquired from the AC Fund and that its holding period of
such assets will include the period during which the assets were held by AC
Fund. See "The Proposed Reorganization -- Federal Income Tax Consequences" in
the combined Proxy Statement/Prospectus.
<PAGE>   335
 
WHAT IF I REDEEM MY AC FUND SHARES BEFORE THE REORGANIZATION TAKES PLACE?
 
  If you choose to redeem your shares of AC Fund before the Reorganization takes
place, the redemption will be treated as a normal sale of shares and will be a
taxable transaction, unless your account is not subject to taxation, such as an
individual retirement account or other tax-qualified retirement plan.
 
  We hope these answers help to clarify the Reorganization proposal for you. If
you still have questions, do not hesitate to call us at 1-800-341-2911. Please
give this matter your prompt attention. We need to receive your proxy before the
shareholder meeting scheduled for September 15, 1995. If shareholders approve
the Reorganization, it is expected to take effect on September 22, 1995.
 
  Thank you for your investment in Van Kampen American Capital Insured Municipal
Fund.
 
                                          Very truly yours,

                               SEPTEMBER 15, 1995
 
  A Special Meeting of Shareholders of Van Kampen American Capital Insured
Municipal Fund (the "AC Fund") will be held at the Hyatt Regency Oak Brook, 1909
Spring Road, Oak Brook, Illinois 60521, on September 15, 1995 at 2:00 p.m. (the
"Special Meeting") for the following purposes:
 
    (1) To approve a plan of reorganization pursuant to which the AC Fund would
  transfer all of its assets and liabilities to the Van Kampen American Capital
  Insured Tax Free Income Fund (the "VK Fund") in exchange for corresponding
  Class A, B and C shares of beneficial interest of the VK Fund, the AC Fund
  would distribute such Class A, B and C shares of the VK Fund to holders of
  Class A, B and C shares of the AC Fund and the AC Fund would be dissolved.
 
    (2) To transact such other business as may properly come before the Special
  Meeting.
 
  The Special Meeting is scheduled to be held jointly with the special meetings
of the respective shareholders of five other Van Kampen American Capital Funds
because the shareholders of each of such funds are expected to consider and vote
on similar matters. In the event that any shareholder of any Van Kampen American
Capital Fund present at the special meetings objects to the holding of a joint
meeting and moves for an adjournment of the meeting of such fund to a time
immediately after the other special meetings so that such fund's special meeting
may be held separately, the persons named as proxies will vote in favor of such
adjournment. Shareholders of each Van Kampen American Capital Fund will vote
separately on each of the proposals relating to their fund, and an unfavorable
vote on a proposal by the shareholders of one fund will not affect the
implementation of such a proposal by another fund if the proposal is approved by
the shareholders of that fund.
 
  Shareholders of record as of the close of business on August 1, 1995 are
entitled to vote at the Special Meeting or any adjournment thereof.
 
                                       For the Board of Trustees,

                          VAN KAMPEN AMERICAN CAPITAL
                             INSURED MUNICIPAL FUND
 
                           PROXY STATEMENT/PROSPECTUS
            RELATING TO THE ACQUISITION OF ASSETS AND LIABILITIES OF
                          VAN KAMPEN AMERICAN CAPITAL
                             INSURED MUNICIPAL FUND
                        BY AND IN EXCHANGE FOR SHARES OF
                          VAN KAMPEN AMERICAN CAPITAL
                          INSURED TAX FREE INCOME FUND
 
  This Proxy Statement/Prospectus is being furnished to shareholders of Van
Kampen American Capital Insured Municipal Fund (the "AC Fund"), a series of Van
Kampen American Capital Tax-Exempt Trust, and relates to the Special Meeting of
Shareholders of the AC Fund (the "Special Meeting") called for the purpose of
approving the proposed reorganization of the AC Fund (the "Reorganization")
which would result in shareholders of the AC Fund in effect exchanging their AC
Fund shares for shares of the Van Kampen American Capital Insured Tax Free
Income Fund (the "VK Fund"), a series of the Van Kampen American Capital Tax
Free Trust, a Delaware business trust (the "VKAC Tax Free Trust"). The
Reorganization would be accomplished as follows: (1) the VK Fund would acquire
all the then existing assets and liabilities of the AC Fund in exchange for
Class A, B and C shares of beneficial interest of the VK Fund (the "Shares");
(2) the AC Fund would distribute the Shares to the AC Fund shareholders holding
the same respective class of shares; and (3) the AC Fund would dissolve and all
shares of the AC Fund would be cancelled.
 
  The VK Fund, an open-end, diversified management investment company, is one of
twelve series of the VKAC Tax Free Trust, which is authorized to issue an
unlimited number of shares of beneficial interest, par value $.01 per share, for
each series authorized by its Board of Trustees. Each series represents
interests in a separate portfolio of securities and other assets, with its own
investment objectives and policies. The investment objective of the VK Fund is
to provide investors with a high level of current income exempt from federal
income tax, which is substantially similar to that of the AC Fund. (See "Summary
- -- Investment Objective and Policies" below.) There can be no assurance that the
VK Fund will achieve its investment objective. The address, principal executive
office and telephone number of the VKAC Tax Free Trust is One Parkview Plaza,
Oakbrook Terrace, Illinois 60181, (708) 684-6000 or (800) 225-2222. The address,
principal executive office and telephone number of the AC Fund is 2800 Post Oak
Boulevard, Houston, Texas 77056, (800) 421-5666. The enclosed proxy and this
Proxy Statement/ Prospectus are first being sent to AC Fund shareholders on or
about August 2, 1995.

A. SUMMARY
 
  The following is a summary of, and is qualified by references to, the more
complete information contained in this Proxy Statement/Prospectus, including the
Agreement and Plan of Reorganization by and between the AC Fund and the VK Fund
attached hereto as Exhibit A (the "Agreement"), the prospectus of the AC Fund
dated August 1, 1995 (the "AC Fund Prospectus") incorporated herein by
reference, and the prospectus of the VK Fund dated July 31, 1995 (the "VK Fund
Prospectus") incorporated herein by reference and accompanying this Proxy
Statement/Prospectus. This Proxy Statement/Prospectus constitutes an offering of
Class A, B and C Shares of the VK Fund only.
 
THE REORGANIZATION
 
  On May 11, 1995, the Board of Trustees of the AC Fund (the "AC Board")
approved the Agreement. The Agreement provides that the AC Fund will transfer
all of its assets and liabilities to the VK Fund in exchange for Class A, B and
C Shares of the VK Fund. At the Closing (as defined herein), the VK Fund will
issue Shares of the VK Fund to the AC Fund, which VK Fund Shares will have an
aggregate net asset value approximately equal in amount to the net asset value
of the AC Fund net assets as of the Closing. See "Distribution, Purchase,
Valuation, Redemption and Exchange of Shares" below. The Agreement provides that
the AC Fund will dissolve pursuant to a plan of liquidation and dissolution to
be adopted by the AC Board following the Closing, and as part of such
dissolution, will distribute to each shareholder of the AC Fund Shares of the
respective class of the VK Fund approximately equal in value to their existing
shares in the AC Fund. All members of the AC Board were elected as trustees of
the VKAC Tax Free Trust on July 21, 1995.
 
  The AC Board has unanimously determined that the Reorganization is in the best
interests of the shareholders of each class of shares the AC Fund and that the
interests of such shareholders will not be diluted as a result of the
Reorganization. Similarly, the Board of Trustees of the VKAC Tax Free Trust (the
"VK Board") has unanimously determined that the Reorganization is in the best
interests of the VK Fund and that the interests of each class of shares of
existing shareholders of the VK Fund will not be diluted as a result of the
Reorganization. Management of the respective funds believes that the proposed
Reorganization of the AC Fund into the VK Fund should allow the VK Fund to
achieve future economies of scale and eliminate certain costs of operating the
AC Fund and the VK Fund separately.
 
  The VK Fund has agreed to pay all of the costs of soliciting approval of the
Reorganization by the AC Fund's Shareholders and related costs of the
 
                                        4
<PAGE>   341
 
Reorganization in the event the Reorganization is completed, including expenses
incurred by the AC Fund. Accordingly, if the Reorganization is completed,
shareholders of the VK Fund after the Reorganization will bear a pro rata
portion of such expenses. If the Reorganization is not completed VKAC will bear
the costs associated with the Reorganization.
 
  The AC Board is asking shareholders of the AC Fund to approve the
Reorganization at a Special Meeting to be held on September 15, 1995. If
shareholders of the AC Fund approve the Reorganization, it is expected that the
Closing will be on September 22, 1995, but it may be at a different time as
described herein.
 
  THE AC BOARD RECOMMENDS THAT YOU VOTE FOR THE REORGANIZATION. APPROVAL OF THE
REORGANIZATION REQUIRES THE FAVORABLE VOTE OF A MAJORITY OF THE OUTSTANDING
SHARES ENTITLED TO VOTE. SEE "VOTING INFORMATION AND REQUIREMENTS."
 
COMPARISONS OF THE VK FUND AND THE AC FUND
 
  The principal changes which would result from the Reorganization are listed
below:
 
  (1) The holders of Class A, B and C shares the AC Fund would become
      shareholders of the same class of Shares, respectively, of the VK Fund.
      The AC Fund and the VK Fund have substantially similar investment
      objectives and follow similar investment strategies.
 
  (2) The VK Fund is managed by Van Kampen American Capital Investment Advisory
      Corp. ("VK Adviser"), an affiliate of the AC Fund's adviser, Van Kampen
      American Capital Asset Management, Inc. ("AC Adviser"). The annual
      advisory fee for the VK Fund is 0.525% of its daily net assets up to $500
      million, 0.50% on the next $500 million, 0.475% on the next $500 million
      and 0.45% on assets over $1,500 million. As of March 31, 1995, the VK
      Fund's net assets were approximately $1,222.3 million.
 
      The annual advisory fee for the AC Fund is 0.60% of its daily net assets
      up to $300 million, 0.55% on the next $300 million and 0.50% thereafter
      (assets are combined with the American Capital High Yield Municipal
      Portfolio, a series of the VKAC Tax Free Income Fund, for purposes of
      calculating management fees.) As of March 31, 1995, the AC Fund's net
      assets were approximately $105.8 million.
 
  (3) Both the AC Fund and the VK Fund offer three classes of shares. Class A
      Shares of the VK Fund and the AC Fund are subject to an initial sales
      charge of up to 4.75%. Purchases of Class A Shares of the VK Fund or the
      AC Fund in amounts of $1,000,000 or more are not subject to an initial
      sales charge but a contingent deferred sales charge of 1.00% may be
      imposed on certain redemptions made within one year after purchase.
      However, the initial sales charge will be waived for Class A Shares
      acquired in the
 
                                        5
<PAGE>   342
 
      Reorganization. Any subsequent purchases of Class A Shares of the VK Fund
      will be subject to a sales charge of up to 4.75% excluding Class A Shares
      purchased through the dividend reinvestment plan. Class B Shares of the VK
      Fund and Class B shares of the AC Fund do not incur a sales charge when
      they are purchased, but generally are subject to a sales charge of 4.00%
      if redeemed within the first year of purchase, which charge is reduced to
      zero over a six year period in the case of the VK Fund and over a five
      year period in the case of the AC Fund. However, Class B Shares of the VK
      Fund acquired in the Reorganization will remain subject to the contingent
      deferred sales charge applicable to Class B shares of the AC Fund. Class C
      Shares of the VK Fund and the AC Fund do not incur a sales charge when
      they are purchased, but are subject to a contingent deferred sales charge
      of 1.00% if redeemed within the first year after purchase.
 
  (4) Both the AC Fund and the VK Fund have adopted distribution plans (the
      "Distribution Plans") pursuant to Rule 12b-1 under the Act, and have
      adopted service plans (the "Service Plans"). Both the VK Fund and the AC
      Fund can pay up to 0.75% of their respective average daily net assets
      attributable to Class B and C shares for reimbursement of certain
      distribution-related expenses. In addition, both the VK Fund and the AC
      Fund can pay up to 0.25% of the their respective average daily net assets
      attributable to Class A, B and C shares for the provision of ongoing
      services to shareholders. Class B Shares of the VK Fund automatically
      convert to Class A Shares after seven years, while Class B shares of the
      AC Fund automatically convert to Class A shares after six years. Unlike
      Class C Shares of the VK Fund, Class C Shares of the AC Fund automatically
      convert to Class A shares after ten years. However, Class B and C Shares
      of the VK Fund acquired in the Reorganization will automatically convert
      to Class A Shares in accordance with the same conversion schedule
      applicable to Class B and C shares of the AC Fund, respectively.
 
  Certain other comparisons between the AC Fund and the VK Fund are discussed
below.
 
  INVESTMENT OBJECTIVES AND POLICIES
 
  The VK Fund and the AC Fund have substantially similar investment objectives,
policies and restrictions. The investment objective of the VK Fund is to provide
investors with a high level of current income exempt from federal income tax.
The investment objective of the AC Fund is to provide investors as high a level
of current interest income exempt from federal income tax as is consistent with
the preservation of capital.
 
  The VK Fund and the AC Fund both attempt to achieve their investment
objectives by generally investing at least 80% of their assets in diversified
portfolios
 
                                        6
<PAGE>   343
 
of insured tax-exempt municipal securities rated investment grade at the time of
investment.
 
  There are certain differences in the investment policies of the VK Fund and
the AC Fund. For instance, the VK Fund has a policy of not investing in private
activity bonds, while the AC Fund has invested approximately 16% of its assets
in such securities. The interest on such private activity bonds is an item of
tax preference subject to the alternative minimum tax on individuals and
corporations. In addition, the VK Fund requires that 100% of its assets be
invested in securities which are insured, while the AC Fund has approximately 3%
of its assets invested in uninsured securities. As the table below indicates,
however, the holdings of the VK Fund and the AC Fund have substantially similar
credit quality.
 
  A comparison of the credit quality of the respective portfolios of the VK Fund
and the AC Fund, as of March 31, 1995, is set forth in the table below.

  ADVISORY AND OTHER FEES
 
  The AC Fund pays AC Adviser a monthly fee based on its average daily net asset
value at the annual rate of 0.60% for the first $300 million, 0.55% on the next
300 million and 0.50% thereafter. Assets of the AC Fund are combined with the
Van Kampen American Capital High Yield Portfolio for the purposes of calculating
management fees. In addition, the AC Fund bears most expenses associated with
its operations and the issuance and repurchase or redemption of its securities,
except for the compensation of trustees affiliated with VKAC, and officers of
the AC Fund who are interested persons of VKAC or its subsidiaries. Total
operating expenses for the AC Fund for the period ended November 30, 1994 were
1.15%, 1.91% and 1.89% with respect to Class A, B and C shares, respectively.
 
  The VK Fund pays VK Adviser a monthly fee based on its average daily net asset
value at the annual rates of 0.525% of the first $500 million, 0.50% on the next
$500 million, 0.475% on the next $500 million and 0.45% thereafter. The advisory
fee for the fiscal year ended December 31, 1994 was .51% of the VK Fund's
average daily net asset value. Further, the VK Fund also bears most expenses
associated with its operations and the issuance and repurchase or redemption of
its securities, except for the compensation of trustees affiliated with VKAC and
officers of the VK Fund who are interested persons of VKAC or its subsidiaries.
The total operating expenses of the VK Fund for the period ended December 31,
1994, as adjusted to take into account the increase in the advisory fee approved
by shareholders of the VK Fund on July 21, 1995, would have been 0.97%, 1.80%
and 1.79% of the average daily net assets attributable to Class A, B and C
shares, respectively, of the VK Fund. For a complete description of the VK
Fund's advisory services, see the respective sections in the VK Fund's
Prospectus and Statement of Additional Information entitled "Investment Advisory
Services" and "Investment Advisory and Other Services -- Investment Advisory
Agreement." For a complete description of the AC Fund's advisory services, see
the respective sections in the AC Fund's Prospectus and Statement of Additional
Information entitled "Investment Advisory Services" and "Investment Advisory
Agreement."
 
  In addition, the VK Fund also has adopted the Distribution Plan with respect
to each class of shares pursuant to Rule 12b-1 under the Act and has adopted the
Service Plan with respect to each class of its shares. The Distribution Plan and
the Service Plan provides that the VK Fund can pay up to 0.25%, 1.00% and 1.00%
of the VK Fund's average daily net assets attributable to the Class A, B and C
shares, respectively, for reimbursement of certain distribution-related expenses
and for the provision of ongoing services to shareholders. The Distribution Plan
and the Service Plan are being implemented through an agreement with Van Kampen
American Capital Distributors, Inc. ("VKAC Distributors"), the distributor of
each class of the VK Fund's shares, sub-agreements between VKAC Distributors and
members of the National Association of Securities Dealers, Inc. (the "NASD") who
are

  Generally, Class A Shares of the VK Fund and the AC Fund are sold at net asset
value applicable at the time of such sale, plus a sales charge of up to 4.75% of
the offering price (which percentage is reduced on investments of $100,000 or
more), and are redeemable at their net asset value applicable at the time of
redemption. Class A shares of the AC Fund are sold at net asset value applicable
at the time of such sale, plus a sales charge of up to 4.75% of the offering
price (which percentage is reduced on investments of $100,000 or more), and are
redeemable at their net asset value applicable at the time of redemption.
Purchases of Class A shares of the VK Fund or the AC Fund in amounts of
$1,000,000 or more are not subject to an initial sales charge but a contingent
deferred sales charge of 1.00% may be imposed on certain redemptions made within
one year of purchase. Class A Shares of the VK Fund acquired in the
Reorganization will not be subject to a sales charge.
 
  Generally, Class B shares do not incur a sales charge when they are purchased,
but generally are subject to a contingent deferred sales charge if redeemed
within a specified period of time from the date of purchase. Class B Shares of
the VK Fund are subject to a contingent deferred sales charge equal to 4.00% of
the lesser of the then current net asset value or the original purchase price on
Class B Shares redeemed during the first year after purchase, which charge is
reduced to zero over a six year period. Class B shares of the AC Fund are
subject to a contingent deferred sales charge equal to 4.00% of the lesser of
the then current net asset value or the original purchase price on Class B
shares redeemed during the first year after purchase, which charge is reduced to
zero over a five year period. However, Class B Shares of the VK Fund acquired in
the Reorganization will remain subject to the contingent deferred sales charge
applicable to Class B shares of the AC Fund.
 
  Generally, Class C shares do not incur a sales charge if redeemed after the
first year of purchase. Both Class C shares of the VK Fund and the AC Fund are
subject to a contingent deferred sales charge equal to 1.00% of the lesser of
the then current net asset value or the original purchase price on such shares
redeemed during the first year after purchase and do not incur a sales charge if
redeemed after the first year from the date of purchase. See "Fee Comparisons"
below. Class C shares of the AC Fund automatically convert to Class A shares
after ten years. Class C
 
                                        9
<PAGE>   346
 
shares of the VK Fund have no such automatic conversion feature. However, Class
C Shares of the VK Fund acquired in the Reorganization will remain subject to
the conversion schedule applicable to Class B shares of the AC Fund.
 
  With respect to fixed income securities, the VK Fund and the AC Fund use
different pricing methodologies in calculating net asset value per share, each
of which is widely used and generally accepted in the mutual fund industry. In
determining net asset value per share, the VK Fund generally values fixed income
portfolio securities once daily by using prices equal to the mean of the last
reported bid and ask price of such securities as of 5:00 p.m. eastern time. When
calculating the net assets of the AC Fund in accordance with this pricing
methodology, the net asset value per share would have been $11.18, $11.18 and
$11.17 on July 21, 1995 for Classes A, B and C, respectively. The AC Fund,
however, generally computes net asset value per share by valuing fixed income
securities using the last reported bid price. When calculating the net assets of
the AC Fund in accordance with this pricing methodology, the net asset value per
share was $11.14, $11.14 and $11.13 on July 21, 1995 for Classes A, B and C,
respectively. In connection with the Reorganization, the net assets of the AC
Fund will be calculated using the current pricing methodology of the VK Fund.
For this reason the value of the VK Fund Shares received in connection with the
Reorganization may be approximately equal in value to the shares of the AC Fund
held immediately prior to the Reorganization rather than identical in value.
 
  The minimum initial investment with respect to each class of shares in the VK
Fund and the AC Fund is $500, although Shares of the VK Fund acquired in
connection with the Reorganization will not be subject to the minimum investment
limitation. The minimum subsequent investment in the VK Fund and the AC Fund is
$25. For a complete description of these arrangements with respect to the VK
Fund, see the section in the VK Fund Prospectus entitled "Purchase of Shares."
For a complete description of these arrangements with respect to the AC Fund,
see the respective sections in the AC Fund's Prospectus and Statement of
Additional Information entitled "Purchase of Shares" and "Purchase and
Redemption of Shares."
 
  Shares of either the AC Fund or the VK Fund may be purchased by check, by
electronic transfer or by bank wire and offer exchange privileges among all
other Van Kampen American Capital open-end mutual funds distributed by VKAC
Distributors (except Van Kampen American Capital Government Target Fund).
 
  Shares of the VK Fund and the AC Fund properly presented for redemption may be
redeemed or exchanged at the next determined net asset value per share (subject
to any applicable deferred sales charge). Shares of either the AC Fund or the VK
Fund may be redeemed or exchanged by mail or by special redemption privileges
(telephone exchange, telephone redemption, by check, or electronic transfer). If
a shareholder of either fund attempts to redeem shares within a short time after
they
 
                                       10
<PAGE>   347
 
have been purchased by check, the respective fund may delay payment of the
redemption proceeds until such fund can verify that payment for the purchase of
the shares has been (or will be) received. No further purchases of the shares of
the AC Fund may be made after the date on which the shareholders of the AC Fund
approve the Reorganization, and the stock transfer books of the AC Fund will be
permanently closed as of the date of Closing. Only redemption requests and
transfer instructions received in proper form by the close of business on the
day prior to the date of Closing will be fulfilled by the AC Fund. Redemption
requests or transfer instructions received by the AC Fund after that date will
be treated by the AC Fund as requests for the redemption or instructions for
transfer of the shares of the VK Fund credited to the accounts of the
shareholders of the AC Fund. Redemption requests or transfer instructions
received by the AC Fund after the close of business on the day prior to the date
of Closing will be forwarded to the VK Fund. For a complete description of these
redemption arrangements, see the section in the VK Fund Prospectus entitled
"Redemption of Shares," and the respective sections in the AC Fund's Prospectus
and Statement of Additional Information entitled "Redemption of Shares" and
"Purchase and Redemption of Shares."
 
  The differences in the distribution, purchase and redemption procedures and
fee structure of the shares of the VK Fund and the shares of the AC Fund are
highlighted in the table below.

FEDERAL INCOME TAX CONSEQUENCES
 
  The Reorganization is intended to qualify as a "reorganization" within the
meaning of Section 368(a)(1) of the Internal Revenue Code of 1986, as amended
(the "Code"). If the Reorganization so qualifies, in general a shareholder of
the AC
 
                                       14
<PAGE>   351
 
Fund will recognize no gain or loss upon the receipt of solely the shares of the
VK Fund pursuant to the Reorganization. Additionally, the AC Fund would not
recognize any gain or loss as a result of the exchange of all of its assets for
the Shares of the VK Fund or as a result of its liquidation. The VK Fund expects
that it will not recognize any gain or loss as a result of the Reorganization,
that it will take a carryover basis in the assets acquired from the AC Fund and
that its holding period of such assets will include the period during which the
assets were held by the AC Fund. See "The Proposed Reorganization -- Federal
Income Tax Consequences."
 
  The above information is only a summary of more complete information contained
in this Proxy Statement/Prospectus and the related Statement of Additional
Information.
 
REASONS FOR THE PROPOSED REORGANIZATION
 
  On December 20, 1994, The Van Kampen Merritt Companies, Inc. acquired from The
Travelers Inc. all of the outstanding capital stock of American Capital
Management & Research, Inc., the parent company of the AC Adviser. Immediately
after the acquisition, American Capital Management & Research, Inc. was merged
into The Van Kampen Merritt Companies, Inc. and the combined entity was renamed
Van Kampen American Capital, Inc. ("VKAC"). The VK Adviser and the AC Adviser
currently are each wholly-owned subsidiaries of VKAC.
 
  On February 10, 1995, the VK Board and the AC Board held a joint meeting to
discuss with management ("Management") of the VK Adviser and the AC Adviser the
costs and potential benefits to shareholders of, among other things, (i)
combining certain funds advised by the VK Adviser and the AC Adviser, including
the VK Fund and the AC Fund, in order to seek to achieve certain economies of
scale and efficiencies, (ii) permitting exchangeability of shares between funds
advised by the VK Adviser and the AC Adviser, (iii) selecting a common transfer
agent to facilitate exchangeability and enhance shareholder services, and (iv)
consolidating the VK Board and the AC Board into a combined board of trustees
(collectively, the "Consolidation").
 
  The VK Board and the AC Board created a joint committee (the "Joint
Committee") to consider the possible costs and benefits to shareholders
associated with the proposed Consolidation, including the combination of the VK
Fund and the AC Fund. The Joint Committee held meetings on February 20, 1995,
March 27, 1995 and April 3, 1995 to consider issues relating to the
Consolidation, review information requested from and provided by Management and
review information requested from and provided by third-party analytical
services.
 
  The VK Board and the AC Board held joint meetings on March 14, 1995 and April
6-7, 1995 to review the findings and recommendations of the Joint
 
                                       15
<PAGE>   352
 
Committee. The VK Board unanimously approved each element of the Consolidation,
including the combination of the VK Fund with the AC Fund, on April 7, 1995,
subject to approval of the Consolidation by the AC Board. The AC Board met May
11, 1995, and unanimously approved each element of the Consolidation, including
the combination of the VK Fund with the AC Fund. Each of the VK Board and the AC
Board also approved submitting the necessary proposals to the respective
shareholders of the VK Fund and the AC Fund to effect the Consolidation.
 
  At separate shareholder meetings held on July 21, 1995, shareholders of the VK
Fund and the AC Fund approved the reorganization of the VK Fund and the AC Fund
into Delaware business trusts (or series thereof) and the combination of the VK
Board and the AC Board. Shareholders of the AC Fund are now being asked to
approve its consolidation with the VK Fund in order to (i) eliminate the
duplication of services that currently exists as a result of the separate
operations of the funds, (ii) seek to achieve economies of scale by combining
the assets of the funds and (iii) potentially reduce transaction costs and
obtain greater portfolio diversity.
 
  In connection with approving the combination of the AC Fund with the VK Fund,
the AC Board considered the costs resulting from the separate operations of the
AC Fund and the VK Fund in light of their substantially similar investment
objective, policies and restrictions. The AC Board also considered the potential
expense savings, economies of scale, reduced per-share expenses and benefits to
the portfolio management process that could result from combining the assets and
operations of the AC Fund and the VK Fund. In this regard, the AC Board reviewed
information provided by the AC Adviser, VK Adviser and VKAC Distributors
relating to the anticipated cost savings to the shareholders of the AC Fund and
the VK Fund as a result of the Reorganization.
 
  In particular, the AC Board considered the probability that the elimination of
duplicative operations and the increase in asset levels of the VK Fund after the
Reorganization would result in the following potential benefits for investors,
although there can, of course, be no assurances in this regard:
 
  (1) ELIMINATION OF SEPARATE OPERATIONS.  Consolidating the AC Fund and the VK
      Fund should eliminate duplication of services that currently exists as a
      result of their separate operations. For example, currently the AC Fund
      and the VK Fund are managed separately by different affiliated investment
      advisers. Consolidating the separate operations of the AC Fund with those
      of the VK Fund should promote more efficient operations on a more cost-
      effective basis.
 
  (2) ACHIEVEMENT OF REDUCED PER SHARE EXPENSES AND ECONOMIES OF SCALE.
      Combining the assets of the AC Fund with the assets of the VK Fund also
      should lead to reduced expenses, on a per share basis, by allowing fixed
      and
 
                                       16
<PAGE>   353
 
      relatively fixed costs, such as accounting, legal and printing expenses,
      to be spread over a larger asset base. An increase in the net asset levels
      of the VK Fund also could result in achieving future economies of scale,
      which should also reduce per share expenses. Any significant reductions in
      expenses on a per share basis should, in turn, have a favorable effect on
      the relative total return of the VK Fund.
 
  (3) BENEFITS TO THE PORTFOLIO MANAGEMENT PROCESS.  Higher net asset levels
      also should enable the VK Fund to purchase larger individual portfolio
      investments that may result in reduced transaction costs and/or other more
      favorable pricing and provide the opportunity for greater portfolio
      diversity.
 
  In determining whether to recommend approval of the Reorganization to
shareholders of the AC Fund, the AC Board considered a number of factors,
including, but not limited to: (1) capabilities and resources of VK Adviser and
other service providers to the VK Fund in the areas of marketing, investment and
shareholder services; (2) expenses and advisory fees applicable to the AC Fund
and the VK Fund before the Reorganization and the estimated expense ratios of
the VK Fund after the Reorganization; (3) the comparative investment performance
of the AC Fund and the VK Fund, as well as the performance of the VK Fund
compared to its peers; (4) the terms and conditions of the Agreement and whether
the Reorganization would result in dilution of AC Fund shareholder interests;
(5) the advantages of eliminating the competition and duplication of effort
inherent in marketing two funds having similar investment objectives, in
addition to the economies of scale realized through the combination of the
funds; (6) the compatibility of the funds' service features available to
shareholders, including the retention of applicable holding periods and exchange
privileges; (7) the costs estimated to be incurred by the respective funds as a
result of the Reorganization; and (8) the anticipated tax consequences of the
Reorganization. Based upon these, and other factors, the AC Board unanimously
determined that the Reorganization is in the best interests of the shareholders
of the AC Fund.
 
B. RISK FACTORS
 
NATURE OF INVESTMENT
 
  Each of the VK Fund and the AC Fund invest primarily in a portfolio of tax
exempt insured municipal securities. Investment in either of the VK Fund or the
AC Fund may not be appropriate for all investors.
 
  Certain investment policies and practices of the VK Fund involve special
risks. Investment in municipal securities involves risk of fluctuation in value
as a result of changes in market rates of interest. Although all of the
municipal securities in which the VK Fund invests will be insured by municipal
bond insurers, no representation can be made as to the ability of any insurer to
meet its commitments
 
                                       17
<PAGE>   354
 
and the insurance does not guarantee the market value of the municipal
securities or the value of the VK Fund's Shares. Other investment policies and
practices also involve special risks, including investment in municipal
securities whose rates of interest vary inversely with market rates of interest,
investment in municipal lease obligations that have "non-appropriation" clauses,
the use of options, futures and interest rate transactions and the use of when
issued and delayed delivery transactions. For a more complete discussion of the
risks of an investment in the VK Fund, see the sections of the VK Fund
Prospectus entitled "Investment Objectives and Policies," "Municipal Securities"
and "Investment Practices."
 
CHANGES IN CERTAIN INVESTMENT PRACTICES
 
  Both the VK Fund and the AC Fund may engage in certain options and financial
futures transactions. However, the VK Fund has greater levels of flexibility in
pursuing its investment objectives through practices such as the ability to make
investments in securities of issuers that are new and unseasoned or in
securities having no ready market. Such transactions involve different risks.
See "The VK Fund" below. For a complete description of the VK Fund's investment
practices, see the section in the VK Fund Prospectus entitled "Investment
Practices" and "Investment Objective and Policies" and the section of the VK
Fund's Statement of Additional Information entitled "Additional Investment
Considerations."

  Management's Discussion of VK Fund Performance as of the Annual Report dated
December 31, 1995 and Management's Discussion of AC Fund Performance as of the
Annual Report dated November 30, 1994 are attached hereto as Exhibit B.
 
  The VK Fund, as a series of VKAC Tax Free Trust, a Delaware business trust,
and the AC Fund, as a Delaware business trust, are governed by their respective
Agreements and Declarations of Trust (each, the "Declaration"), their respective
Bylaws and applicable Delaware law.
 
D. THE PROPOSED REORGANIZATION
 
  The material features of the Agreement are summarized below. This summary does
not purport to be complete and is subject in all respects to the provisions of,
and is qualified in its entirety by reference to, the Agreement, a copy of which
is attached hereto as Exhibit A. The affirmative vote of a majority of the
outstanding shares entitled to vote is required to approve the Agreement at a
meeting of shareholders at which a quorum is present.
 
TERMS OF THE AGREEMENT
 
  Pursuant to the Agreement, the VK Fund series of the VKAC Tax Free Trust will
acquire all of the assets and liabilities of the AC Fund on the date of the
Closing in exchange for Class A, B and C Shares, respectively, of the VK Fund.
 
  Subject to AC Fund shareholder approval of the Reorganization, the closing
(the "Closing") will occur within 15 business days after the later of the
receipt of all necessary regulatory approvals and the final adjournment of the
Special Meeting or such later date as soon as practicable thereafter as the VK
Fund and the AC Fund may mutually agree.
 
  On the date of Closing, the AC Fund will transfer to the VK Fund all of the
assets and liabilities of the AC Fund. The VKAC Tax Free Trust will in turn
transfer to the AC Fund a number of Class A, B and C Shares of the VK Fund equal
in value to the value of the net assets of the AC Fund transferred to the VK
Fund as of the date of Closing as determined in accordance with the valuation
method described in the VK Fund's then current prospectus. In order to minimize
any potential for undesirable federal income and excise tax consequences in
connection with the Reorganization, the VK Fund and the AC Fund may distribute
on or before the Closing all or substantially all of their respective
undistributed net investment income (including net capital gains) as of such
date.
 
                                       19
<PAGE>   356
 
  The AC Fund expects to distribute the Class A, B and C Shares of the VK Fund
to the shareholders of the AC Fund promptly after the Closing. The AC Fund will
then dissolve pursuant to a plan of liquidation and dissolution adopted by the
AC Board.
 
  The AC Fund and the VKAC Tax Free Trust have made certain representations and
warranties to each other regarding their capitalizations, status and conduct of
business.
 
  Unless waived in accordance with the Agreement, the obligations of the parties
to the Agreement are conditioned upon, among other things:
 
    1. the approval of the Reorganization by the AC Fund's shareholders;
 
    2. the absence of any rule, regulation, order, injunction or proceeding
       preventing or seeking to prevent the consummation of transactions
       contemplated by the Agreement;
 
    3. the receipt of all necessary approvals, registrations and exemptions
       under federal and state laws;
 
    4. the truth in all material respects as of the Closing of the
       representations and warranties of the parties and performance and
       compliance in all material respects with the parties' agreements,
       obligations and covenants required by the Agreement;
 
    5. the effectiveness under appliable law of the registration statement of
       the VK Fund of which this Proxy Statement/Prospectus forms a part and the
       absence of any stop orders under the Securities Act pertaining thereto;
       and
 
    6. the receipt of opinions of counsel relating to, among other things, the
       tax free nature of the Reorganization.
 
  The Agreement may be terminated or amended by the mutual consent of the
parties either before or after approval thereof by the shareholders of the AC
Fund, provided that no such amendment after such approval shall be made if it
would have a material adverse affect on the interests of AC Fund shareholders.
The Agreement may also be terminated by the non-breaching party if there has
been a material misrepresentation, material breach of any representation or
warranty, material breach of contract or failure of any condition to Closing.
 
  The AC Board recommends that you vote to approve the Reorganization, as it
believes the Reorganization is in the best interests of the AC Fund's
shareholders and that the interests of AC Fund's existing shareholders will not
be diluted as a result of consummation of the proposed Reorganization.

DESCRIPTION OF SECURITIES TO BE ISSUED
 
  SHARES OF BENEFICIAL INTEREST
 
  Beneficial interests in the VK Fund being offered hereby are represented by
transferable Class A, B and C Shares, par value $.01 per share. The VKAC Tax
Free Trust's Declaration of Trust permits the trustees, as they deem necessary
or desirable, to create one or more separate investment portfolios and to issue
a separate series of shares for each portfolio and subject to compliance with
the Act to further sub-divide the shares of a series into one or more classes of
shares for such portfolio.
 
  VOTING RIGHTS OF SHAREHOLDERS
 
  Holders of shares of the VK Fund are entitled to one vote per share on matters
as to which they are entitled to vote; however, separate votes generally are
taken by each series on matters affecting an individual series. The Declaration
of VKAC Tax Free Trust and the Declaration of AC Fund are substantially
identical, except that the Declaration of the VKAC Tax Free Trust permits the VK
Board or shareholders to remove a trustee with or without cause by the act of
two-thirds of such trustees or shareholders, respectively. The Declaration of
the AC Fund permits (i) the AC Fund to remove a trustee with cause by the act of
two-thirds of the trustees and (ii) shareholders holding a majority of the
shares of each series outstanding to remove a trustee with or without cause. The
Declaration of the AC Fund also requires the approval of 80% of the trustees in
office or majority vote of the shares of each series then outstanding to amend
these provisions.
 
  Each of the VK Fund and the AC Fund operate as a diversified, open-end
management investment company registered with the SEC under the Act. Therefore,
in addition to the specific voting rights described above, shareholders of the
VK Fund, as well as shareholders of the AC Fund, are entitled, under current
law, to vote with respect to certain other matters, including changes in
fundamental investment policies and restrictions and the ratification of the
selection of independent auditors. Moreover, under the Act, shareholders owning
not less than 10% of the outstanding shares of the AC Fund or VK Fund may
request that the respective board of trustees call a shareholders' meeting for
the purpose of voting upon the removal of trustee(s).
 
CONTINUATION OF SHAREHOLDER ACCOUNTS AND PLANS; SHARE CERTIFICATES
 
  If the Reorganization is approved, the VK Fund will establish an account for
each AC Fund shareholder containing the appropriate number of Shares of the VK
Fund. The shareholder services and shareholder programs of the VK Fund and the
AC Fund have already been substantially conformed as part of the Consolidation.
Shareholders of the AC Fund who are accumulating AC Fund shares under the
dividend reinvestment plan, or who are receiving payment under the systematic
 
                                       21
<PAGE>   358
 
withdrawal plan with respect to AC Fund shares, will retain the same rights and
privileges after the Reorganization in connection with the VK Fund Class A, B or
C Shares, respectively, received in the Reorganization through substantially
similar plans maintained by the VKAC Tax Free Fund. Van Kampen American Capital
Trust Company will continue to serve as custodian for the assets of AC Fund
Shareholders held in IRA accounts after the Reorganization. Such IRA investors
will be sent appropriate documentation to confirm Van Kampen American Capital
Trust Company's custodianship.
 
  It will not be necessary for shareholders of the AC Fund to whom certificates
have been issued to surrender their certificates. Upon liquidation of the AC
Fund, such certificates will become null and void.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a general discussion of the material federal income tax
consequences of the Reorganization to shareholders of the AC Fund and
shareholders of the VK Fund. It is based upon the Code, legislative history,
Treasury regulations, judicial authorities, published positions of the Internal
Revenue Service (the "Service") and other relevant authorities, all as in effect
on the date hereof and all of which are subject to change or different
interpretations (possibly on a retroactive basis). This summary is limited to
shareholders who hold their AC Fund shares as capital assets. No advance rulings
have been or will be sought from the Service regarding any matter discussed in
this Proxy Statement/Prospectus. Accordingly, no assurances can be given that
the Service could not successfully challenge the intended federal income tax
treatment described below. Shareholders should consult their own tax advisors to
determine the specific federal income tax consequences of all transactions
relating to the Reorganization, as well as the effects of state, local and
foreign tax laws.
 
  The Reorganization is intended to qualify as a "reorganization" within the
meaning of Section 368(a)(1) of the Code. It is a condition to closing that the
VK Fund and the AC Fund receive an opinion from O'Melveny & Myers substantially
to the effect that, for federal income tax purposes:
 
  1. The acquisition by the VK Fund of the assets of the AC Fund in exchange
solely for Class A, B and C Shares of the VK Fund and the assumption by the VK
Fund of the liabilities of the AC Fund will qualify as a tax-free reorganization
within the meaning of Section 368(a)(1) of the Code.
 
  2. No gain or loss will be recognized by the AC Fund or the VK Fund upon the
transfer to the VK Fund of the assets of the AC Fund in exchange solely for the
Class A, B and C Shares of the VK Fund and the assumption by the VK Fund of the
liabilities of the AC Fund.
 
                                       22
<PAGE>   359
 
  3. The VK Fund's basis in the AC Fund assets received in the Reorganization
will, in each instance, equal the basis in such assets in the hands of the AC
Fund immediately prior to the transfer, and the VK Fund's holding period of such
assets will, in each instance, include the period during which the assets were
held by the AC Fund.
 
  4. No gain or loss will be recognized by the shareholders of the AC Fund upon
the exchange of their shares of the AC Fund solely for the Class A, B or C
Shares, respectively, of the VK Fund.
 
  5. The aggregate tax basis of the Class A, B and C Shares of the VK Fund
received by the shareholders of the AC Fund will be the same as the aggregate
tax basis of the shares of the AC Fund surrendered in exchange therefor.
 
  6. The holding period of the Class A, B and C Shares of the VK Fund received
by the shareholders of the AC Fund will include the holding period of the shares
of the AC Fund surrendered in exchange therefor if such surrendered shares of
the AC Fund are held as capital assets by such shareholder.
 
  In rendering its opinion, O'Melveny & Myers may rely upon certain
representations of the management of the AC Fund and the VKAC Trust and assume
that the Reorganization will be consummated as described in the Agreement and
that redemptions of shares of the AC Fund occurring prior to the Closing will
consist solely of redemptions in the ordinary course of business.
 
  The VK Fund intends to be taxed under the rules applicable to regulated
investment companies as defined in Section 851 of the Code, which are the same
rules currently applicable to the AC Fund and its shareholders.

March 31, 1995 were 1.99%, 5.42%, 6.81% and 9.17% in respect of its Class A

Reorganization.
 
  The total return figures above assume reinvestment of all dividends and
distributions. They are not necessarily indicative of future results. The
performance of a fund is a result of conditions in the securities markets,
portfolio management and operating expenses. Although information such as that
shown above is useful in reviewing a fund's performance and in providing some
basis for comparison with other investment alternatives, it should not be used
for comparison with other investments using different reinvestment assumptions
or time periods.
 
RATIFICATION OF INVESTMENT OBJECTIVE, POLICIES AND RESTRICTIONS OF THE VK FUND
 
  Approval of the Reorganization will constitute the ratification by AC Fund
shareholders of the investment objective, policies and restrictions,
Distribution Plan and Advisory Agreement of the VK Fund. For a discussion of the
investment objective, policies and restrictions of the VK Fund, see "Summary --
Comparison of the VK Fund and AC Fund" and the VK Fund Prospectus accompanying
this Proxy Statement/Prospectus. Approval of the Reorganization will constitute
approval of amendments to any of the fundamental investment restrictions of the
AC Fund that might otherwise be interpreted as impeding the Reorganization, but
solely for the purpose of and to the extent necessary for, consummation of the
Reorganization.
 
LEGAL MATTERS
 
  Certain legal matters concerning the issuance of Class A, B and C Shares of
the VK Fund will be passed on by Skadden, Arps, Slate, Meagher & Flom, 333 West
Wacker Drive, Chicago, Illinois 60606, counsel to the VK Fund. Wayne W. Whalen,

EXPENSES
 
  The expenses of the Reorganization, including expenses incurred by the AC Fund
will be borne by the VK Fund after the Reorganization. Accordingly, if the
Reorganization is completed the VK Fund and its shareholders after the
Reorganization will bear such expenses of the Reorganization. If the
Reorganization is not completed VKAC will bear the costs associated with the
Reorganization. The AC Board has determined that the arrangements regarding the
payment of expenses and other charges relating to the Reorganization are fair
and equitable.
 
E. RECOMMENDATION OF THE AC BOARD
 
  The AC Board has unanimously approved the Agreement and has determined that
participation in the Reorganization is in the best interests of the shareholders
of the AC Fund. THE AC BOARD RECOMMENDS VOTING FOR THE PROPOSED REORGANIZATION.
 
                          OTHER MATTERS THAT MAY COME
                           BEFORE THE SPECIAL MEETING
 
  It is not anticipated that any action will be asked of the shareholders of the
AC Fund other than as indicated above, but if other matters are properly brought
before the Special Meeting, it is intended that the persons named in the proxy
will vote in accordance with their judgment.

Oakbrook Terrace, Illinois 60181. To be considered for presentation at a
shareholders' meeting, rules promulgated by the SEC require that, among other
things, a shareholder's proposal must be received at the offices of the VK Fund
a
 
                                       27

reasonable time before a solicitation is made. Timely submission of a proposal
does not necessarily mean that such proposal will be included.
 
                      VOTING INFORMATION AND REQUIREMENTS
 
  Each valid proxy given by a shareholder of the AC Fund will be voted by the
person named in the proxy in accordance with the designation on such proxy on
the Reorganization proposal and as the persons named in the proxy may determine
on such other business as may come before the Special Meeting on which
shareholders are entitled to vote. If no designation is made, the proxy will be
voted by the persons named in the proxy as recommended by the AC Board "FOR"
approval of the Reorganization.
 
  Shareholders who execute proxies may revoke them at any time before they are
voted by filing with the Fund a written notice of revocation, by delivering a
duly executed proxy bearing a later date, or by attending the Special Meeting
and voting in person.
 
  The giving of a proxy will not affect your right to vote in person if you
attend the Special Meeting and wish to do so.
 
  The presence in person or by proxy of the holders of a majority of the
outstanding shares entitled to vote is required to constitute a quorum at the
Special Meeting. APPROVAL OF THE REORGANIZATION WILL REQUIRE THE FAVORABLE VOTE
OF THE HOLDERS OF A MAJORITY OF THE OUTSTANDING SHARES OF THE AC FUND ENTITLED
TO VOTE AT THE SPECIAL MEETING AT WHICH A QUORUM IS CONSTITUTED. Shares not
voted with respect to a proposal due to an abstention or broker non-vote will be
deemed votes not cast with respect to such proposal, but such shares will be
deemed present for quorum purposes.
 
  In the event that sufficient votes in favor of the Reorganization are not
received by the scheduled time of the Special Meeting, the persons named in the
proxy may propose and vote in favor of one or more adjournments of the Special
Meeting to permit further solicitation of proxies. If sufficient shares were
present to constitute a quorum, but insufficient votes had been cast in favor of
the Reorganization to approve it, proxies would be voted in favor of adjournment
only if the AC Board determined that adjournment and additional solicitation was
reasonable and in the best interest of the shareholders of the AC Fund, taking
into account the nature of the proposal, the percentage of the votes actually
cast, the percentage of negative votes, the nature of any further solicitation
that might be made and the information provided to shareholders about the
reasons for additional solicitation. Any such adjournment will require the
affirmative vote of the holders of a majority of the outstanding shares voted at
the session of the Special Meeting to be adjourned.

  Proxies of shareholders of the AC Fund are solicited by the AC Board. The cost
of solicitation will be paid by the VK Fund after the Reorganization if the
Reorganization is completed. If the Reorganization is not completed VKAC will
bear the costs associated with the Reorganization. In order to obtain the
necessary quorum at the Special Meeting, additional solicitation may be made by
mail, telephone, telegraph or personal interview by representatives of the AC
Fund, the AC Adviser or VKAC, or by dealers or their representatives. In
addition, such solicitation servicing may also be provided by Applied Mailing
Systems, a solicitation firm located in Boston, Massachusetts, at a cost
estimated to be approximately $17,500, plus reasonable expenses.

     E. SHAREHOLDERS MEETING  The AC Trust shall call a meeting of the AC Fund
shareholders to be held as promptly as practicable for the purpose of voting
upon the approval of this Agreement and the transactions contemplated herein,
and shall furnish a copy of the Proxy Statement/Prospectus and form of proxy to

     G. DISTRIBUTION OF THE SHARES.  At Closing the AC Trust covenants that
it shall cause to be distributed the VKM Fund Shares in the proper pro rata
amount for the benefit of AC Fund's shareholders and such that neither the AC
Trust nor the AC Fund shall continue to hold amounts of said shares so as to

to use all reasonable efforts to cooperate with the VKM Trust and the VKM

or similar fee in connection with any of the transactions contemplated by this
Agreement, and each party shall hold the other harmless from and against any all
claims, liabilities or obligations with respect to any such fees, commissions or
expenses asserted by any person to be due or payable in connection with any of
the transactions contemplated by this Agreement on the basis of any act or
statement alleged to have been made by such first party or its affiliate.

press release or make any public statement prior to such consultation, except as
may be required by law or the rules of any national securities exchange on which
such party's securities are traded.
 
     K. TAX STATUS OF REORGANIZATION.  The intention of the parties is that the
transaction will qualify as a reorganization within the meaning of Section
368(a) of the Code. Neither the VKM Trust, the VKM Fund, the AC Trust nor the 
AC Fund shall take any action, or cause any action to be taken (including, 
without limitation, the filing of any tax return) that is inconsistent with 
such treatment or results in the failure of the transaction to qualify as a 
reorganization within meaning of Section 368(a) of the Code. At or prior to 
the Closing Date, the VKM Trust, the VKM Fund, the AC Trust and the AC Fund 
will take such action, or cause such action to be taken, as is reasonably 
necessary to enable O'Melveny & Myers, counsel to the AC Trust and the AC 
Fund, to render the tax opinion required herein.
 
     L. DECLARATION OF DIVIDEND.  At or immediately prior to the Closing Date,
the AC Fund shall declare and pay to its stockholders a dividend or other
distribution in an amount large enough so that it will have distributed 
substantially all (and in any event not less than 98%) of its investment 
company taxable income (computed without regard to any deduction for dividends 
paid) and realized net capital gain, if any, for the current taxable year 
through the Closing Date.

VKM Fund as a  series of the VKM Trust pursuant to the terms of the Declaration

<PAGE>   375
 
execution of this Agreement have been duly authorized and approved by

delivered by the VKM Trust and (assuming the Agreement is a valid and binding
obligation of the other parties thereto) is a valid and binding obligation of
the VKM Trust; (v) neither the execution or delivery by the VKM Trust of this
Agreement nor the consummation by the VKM Trust or VKM Fund of the transactions
contemplated thereby contravene the VKM Trust's Declaration of Trust, or, to
the best of their knowledge, violate any provision of any statute or any
published regulation or any judgment or order disclosed to us by the VKM Trust
as being applicable to the VKM Trust or the VKM Fund; (vi) to the best of their 
knowledge based solely on the certificate of an appropriate officer of the VKM
Trust attached hereto, there is no pending or threatened litigation which would

the VKM Fund or might have a material adverse effect on the value of any assets
of the VKM Fund; (vii) the VKM Fund's Shares have been duly authorized and upon

statements and schedules and other financial and statistical data included or
incorporated by reference therein and subject to usual and customary
qualifications with respect to Rule 10b-5 type opinions, as of the effective
date of the Registration Statement filed pursuant to the Agreement, the
portions thereof pertaining to VKM Trust and the VKM Fund comply as to form in
all material respects with the requirements of the Securities Act, the
Securities Exchange Act and the 1940 Act and the rules and regulations of the
Commission thereunder and no facts have come to counsel's attention which would
cause them to believe that as of the effectiveness of the portions of the
Registration Statement applicable to VKM Trust and VKM Fund, the Registration
Statement contained any untrue statement of a material fact or omitted to state
any material fact required to be stated therein or necessary to make the
statements therein not misleading; and (ix) to the best of their knowledge and
information and subject to the qualifications set forth below, the execution
and delivery by the VKM Trust of the Agreement and the consummation of the
transactions therein contemplated do not require, under the laws of the States
of Delaware or Illinois or the federal laws of the United States, the consent,
approval, authorization, registration, qualification or order of, or filing
with, any court or governmental agency or body (except such as have been
obtained). Counsel need express no opinion, however, as to any such consent,
approval, authorization, registration, qualification, order or filing (a) which
may be required as a result of the involvement of other parties to the
Agreement in the transactions contemplated by the Agreement because of their
legal or regulatory status or because of any other facts specifically
pertaining to them; (b) the absence of which does not deprive the AC Trust or
the AC Fund of any material benefit under the Agreement; or (c) which can be
readily obtained without significant delay or expense to the AC Trust or the AC
Fund, without loss to the AC Trust or the AC Fund of any material benefit under
the Agreement and without any material adverse effect on the AC Trust or the AC
Fund  during the period such consent, approval, authorization, registration, 
qualification or order was obtained. The foregoing opinion relates only to 
consents, approvals, authorizations, registrations, qualifications, orders or 
filings under (a) laws which are specifically referred to in this opinion, (b) 
laws of the States of Delaware and Illinois and the United States of America 
which, in counsel's experience, are normally applicable to transactions of the 
type provided for in the Agreement and (c) court orders and judgments disclosed
to us by the VKM Trust in connection with this opinion. In addition, although 
counsel need not specifically consider the possible applicability to the VKM 
Trust of any other laws, orders or judgments, nothing has come to their 
attention in connection with their representation of the VKM Trust and the VKM 
Fund in this transaction that has caused them to conclude that any other 
consent, approval, authorization, registration, qualification, order or filing 
is required.
 
     H. OFFICER CERTIFICATES. The AC Trust shall have received a certificate of
an authorized officer of the VKM Trust, dated as of the Closing Date, certifying

                                       11
<PAGE>   377
 
to any such consent, approval, authorization, registration, qualification, order
or filing (a) which may be required as a result of the involvement of other
parties to the Agreement in the transactions contemplated by the Agreement

     11.   SURVIVAL OF WARRANTIES AND INDEMNIFICATION.
 
     (A) SURVIVAL.  The representations and warranties included or provided for
herein, or in the Schedules or other instruments delivered or to be delivered
pursuant hereto, shall survive the Closing Date for a three year period except
that any representation or warranty with respect to taxes shall survive for the

covenants and agreements included or provided for herein shall survive and be
continuing obligations in accordance with their terms. The period for which a
representation, warranty, covenant or agreement survives shall be referred to
hereinafter as the "Survival Period." Notwithstanding anything set forth in the
immediately preceding sentence, the VKM Trust's and the AC Trust's right to seek
indemnity pursuant to this Agreement shall survive for a period of ninety (90)
days beyond the expiration of the Survival Period of the representation,
warranty, covenant or agreement upon which indemnity is sought. In no event

     (B) INDEMNIFICATION.  Each party (an "Indemnitor") shall indemnify and
hold the other and its officers, directors, agents and persons controlled by or
controlling any of them (each an "Indemnified Party") harmless from and against
any and all losses, damages, liabilities, claims, demands, judgments,
settlements, deficiencies, taxes, assessments, charges, costs and expenses of
any nature whatsoever (including reasonable attorneys' fees) including amounts
paid in satisfaction of judgments, in compromise or as fines and penalties, and
counsel fees reasonably incurred by such Indemnified Party in connection with 
the defense or disposition of any claim, action, suit or other proceeding,
whether civil or criminal, before any court or administrative or investigative
body in which such Indemnified Party may be or may have been involved as a
party or  otherwise or with which such Indemnified Party may be or may have
been threatened,  (collectively, the "Losses") arising out of or related to any
claim of a breach of any representation, warranty or covenant made herein by
the Indemnitor; provided, however, that no Indemnified Party shall be
indemnified hereunder against any Losses arising directly from such Indemnified
Party's (i) willful misfeasance, (ii) bad faith, (iii) gross negligence or (iv)
reckless disregard of the duties involved in the conduct of such Indemnified
Party's position.
        
     (C) INDEMNIFICATION PROCEDURE.  The Indemnified Party shall use its best
efforts to minimize any liabilities, damages, deficiencies, claims, judgments,
assessments, costs and expenses in respect of which indemnity may be sought
hereunder. The Indemnified Party shall given written notice to Indemnitor within
the earlier of ten (10) days of receipt of written notice to Indemnitor or
thirty (30) days from discovery by Indemnified Party of any matters which may
give rise to a claim for indemnification or reimbursement under this Agreement.
The failure to give such notice shall not affect the right of Indemnified Party
to indemnity hereunder unless such failure has materially and adversely affected
the rights of the Indemnitor; provided that in any event such notice shall have
been given prior to the expiration of the Survival Period. At any time after ten
(10) days from the giving of such notice, Indemnified Party may, at its option,
resist, settle or otherwise compromise, or pay such claim unless it shall have
received notice from Indemnitor that Indemnitor intends, at Indemnitor's sole
cost and expense, to assume the defense of any such matter, in which case
Indemnified Party shall have the right, at no cost or expense to Indemnitor, to
participate in such defense. If Indemnitor does not assume the defense of such
matter, and in any event until Indemnitor states in writing that it will assume
the defense, Indemnitor shall pay all costs of Indemnified Party arising out of
the defense until the defense is assumed; provided, however, that Indemnified
Party shall consult with Indemnitor and obtain Indemnitor's consent to any
payment or settlement of any such claim. Indemnitor shall keep Indemnified Party
fully apprised at all times as to the status of the defense. If Indemnitor does
not assume the defense, Indemnified Party shall keep Indemnitor apprised at all
times as to the status of the defense. Following indemnification as provided for
hereunder, Indemnitor shall be subrogated to all rights of Indemnified Party
with respect to all third parties, firms or corporations relating to the matter
for which indemnification has been made.

                           MANAGEMENT'S DISCUSSION OF
                        VK FUND AND AC FUND PERFORMANCE
 
  Management's Discussion of VK Fund Performance as of the Annual Report dated
December 31, 1995.
 
  The VK Fund's performance during its fiscal year ended December 31, 1994, was
impacted by rising rates and inflation concerns. The Federal Reserve Board (the
"Fed") raised the Fed Funds rate--the rate banks charge each other for overnight
loans--from 3 percent to 5.5 percent during 1994, pushing interest rates to
their highest level in three years. As rates rose, so did yields on fixed-income
securities. The yield on 30-year Treasury bonds, for example, began the year at
6.35 percent and increased to a high of 8.16 percent, before ending the year at
7.89 percent. However, since yields and prices move in opposite directions, this
had a negative impact on prices of fixed-income securities. Additionally, low
interest rates during the early part of the year prompted many issuers to refund
their debt, and the income from the higher-yielding issues that were refunded
could not be replaced in the current environment.
 
  Equity investors, meanwhile, worried that higher interest rates would increase
corporate borrowing costs and depress earnings. These factors combined to push
the stock market down during much of the year, and resulted in the Standard &
Poor's 500-Stock Index achieving a total return for the year of just 1.36
percent. This index is a broad-based, unmanaged indicator of general stock
market performance.
 
  The Fed remains concerned about inflation, and probably will raise interest
rates again this year. Many economists expect inflation to increase in 1995 at
an annual rate of about 3.5 percent, although consumer prices, which are a key
inflation measure, rose only 2.7 percent last year. Analysts point to a steady
increase in consumer spending, especially for durable goods like automobiles and
major appliances, as an indication that the inflation rate will rise.
Additionally, the national unemployment rate is below 6%, which could force
employers to pay more for employees. Labor costs account for about two-thirds of
what consumers pay for goods and services.
 
  Clearly, consumers are feeling better about the economy. The consumer
confidence index reached a four-and-a-half year high in December, rising to
102.2 from 100.4 in November. Consumer confidence was boosted by the increase in
jobs and personal income.

(1) Assumes reinvestment of all distributions for the period ended December 31,
    1994, and does not include payment of the maximum sales charge (4.65% for A
    shares) or contingent deferred sales charge (4% for B shares; 1% for C
    shares). Effective January 16, 1995, the maximum sales charge for Class A
    Shares was changed to 4.75%.
 
(2) Standardized total return for the period ended December 31, 1994.
 
(3) Distribution rate represents the monthly annualized distributions of the
    Fund at end of December 1994, and not the earnings of the Fund.
 
(4) Taxable equivalent calculations reflect a federal income tax rate of 36%.
 
(5) SEC Yield is a standardized calculation prescribed by the Securities and
    Exchange Commission for determining the amount of net income a portfolio
    should theoretically generate for the 30-day period ending December 30,
    1994.
 
  The terms of the insurance are more fully described in the VK Fund Prospectus;
no representation is made as to the insurer's ability to meet its commitments.
In addition, the insurance does not remove market risk, as it does not apply to
the value of the securities in the Fund's portfolio, which may increase or
decrease depending on interest rates and other factors affecting the municipal
credit markets.
 
  Past performance does not guarantee future results. Investment return and net
asset value will fluctuate with market conditions. An investor's shares, when
redeemed, may be worth more or less than their original cost.

                        1 Year Avg. Annual    =  (10.86%)
                        5 Year Avg. Annual    =    5.41%

                        Inception Avg. Annual =    8.85%

  The following graph compares the value of an investment in the VK Fund's
Class A shares with the value of an investment in the securities comprising the
Lehman Brothers Municipal Bond Index from December 1984 through December 1994,
the last trading day of fiscal year 1994, based upon a $10,000 investment in
Class A shares of the VK Fund and in the securities comprising such index as of
December 1984. The approximate values of such an investment at the end of each
fiscal year were:

1985:  Class A shares of VK Fund  --  $11,700, Lehman Index  --  $12,230;
1986:  Class A shares of VK Fund  --  $14,000, Lehman Index  --  $14,600;
1987:  Class A shares of VK Fund  --  $14,000, Lehman Index  --  $14,800;
1988:  Class A shares of VK Fund  --  $15,600, Lehman Index  --  $16,300;
1989:  Class A shares of VK Fund  --  $17,100, Lehman Index  --  $18,100;
1990:  Class A shares of VK Fund  --  $18,300, Lehman Index  --  $19,400;
1991:  Class A shares of VK Fund  --  $20,250, Lehman Index  --  $21,750;
1992:  Class A shares of VK Fund  --  $22,200, Lehman Index  --  $23,650;
1993:  Class A shares of VK Fund  --  $24,900, Lehman Index  --  $26,550;
1994:  Class A shares of VK Fund  --  $23,350, Lehman Index  --  $25,200.
 
  Performance of Class B and C Shares may vary from Class A Shares illustrated
above due to distribution and administrative expense differentials applicable to
these classes.
 
  The Lehman Index is unmanaged and expense free. Its performance does not
reflect transaction and other costs applicable to the VK Fund's actively managed
portfolio.
 
  Past performance is not predictive of future performance.
 
  Management's Discussion of AC Fund Performance as of the Annual Report dated
November 30, 1994.
 
  The AC Fund invests in long-term municipal bonds with the objective of
providing as high a level of current income exempt from federal income taxes as
is consistent with its investment policies. During the fiscal year ended
November 30, 1994, the performance of the AC Fund was hampered by repeated
increases in interest rates, which reduce the supply of both new issues and
refundings.
 
  Rising interest rates caused a significant decline in both the number and
dollar value of new issues and refundings. Refundings occur when municipalities
issue new, lower-yielding debt to replace existing higher-yielding bonds. The
decrease in
<PAGE>   384
 
supply made it more difficult to find securities to purchase, but those that
were available carried higher yields, which helped the AC Fund's portfolio
dividend.
 
  As the interest rate environment changed, the AC Fund placed more emphasis on
longer-term bonds, which offer a higher yield, while maintaining the AC Fund's
high credit quality. At the end of the reporting period, more than 90% of the
municipal bonds in the AC Fund were insured for the timely payment of principal
at maturity and, as a result, were AAA-rated bonds in credit quality.
 
  The Class A shares and Class B shares of the AC Fund outperformed the AC
Fund's benchmark -- the Lehman Brothers Municipal Bond Index -- during the
reporting period. Class A shares of the AC Fund achieved a total return at net
asset value (without a sales charge) of -3.88%, including reinvestment of
dividends totalling $.6075 per share. Class B shares achieved a total return at
net asset value of -4.52%, including reinvestment of dividends totalling $.5235
per share. Class C shares achieved a total return at net asset value of -5.38%,
including reinvestment of dividends totalling $.509 per share.
 
  The Lehman Brothers Municipal Bond Index, an unmanaged index used as a
benchmark for many municipal bond funds, achieved a total return of -5.25%. The
Index does not reflect any commissions or fees that would be paid by an investor
purchasing the securities it represents.

    Van Kampen American Capital Investment Advisory Corp. is the investment
adviser for both the Insured Fund and the California Insured Fund (each a "Fund"
or collectively the "Funds"). There is no assurance that the Funds will achieve
their respective investment objectives. This Prospectus sets forth certain
information about the Funds that a prospective investor should know before
investing in either of the Funds. Please read it carefully and retain it for
future reference. Each Fund's address is One Parkview Plaza, Oakbrook Terrace,
Illinois 60181, and each Fund's telephone number is (800) 421-5666.
 
    The Funds currently offer three classes of shares (the "Alternative Sales
Arrangements") which may be purchased at a price equal to their net asset value
per share, plus sales charges which, at the election of the investor, may be
imposed (i) at the time of purchase ("Class A Shares") or (ii) on a contingent
deferred basis (Class A Share accounts over $1 million, "Class B Shares" and
"Class C Shares"). The Alternative Sales Arrangements permit an investor to
choose the method of purchasing shares that is more beneficial to the investor,
taking into account the amount of the purchase, the length of time the investor
expects to hold the shares and other circumstances.
 
    Each class of shares pays ongoing distribution and service fees at an
aggregate annual rate of (i) for Class A Shares, up to 0.25% of a Fund's average
daily net assets attributable to the Class A Shares, (ii) for Class B Shares, up
to 1.00% of a Fund's average daily net assets attributable to the Class B Shares
and (iii) for Class C Shares, up to 1.00% of a Fund's average daily net assets
attributable to the Class C Shares. Investors should understand that the purpose
and function of the deferred sales charge and the distribution and service fees
with respect to the Class A Share accounts over $1 million, Class B Shares and
the Class C Shares are the same as those of the initial sales charge and
distribution and service fees with respect to the Class A Share accounts below
$1 million. Each share of a Fund represents an identical interest in the
investment portfolio of such Fund and has the same rights, except that (i) each
class of shares bears those distribution fees, service fees and administrative
expenses applicable to the respective class of shares as a result of its sales
arrangements, which will cause the different classes of shares to have different
expense ratios and to pay different rates of dividends, (ii) each class has
exclusive voting rights with respect to those provisions of such Fund's Rule
12b-1 distribution plan which relate only to such class and (iii) the classes
have different exchange privileges. Class B Shares of each Fund automatically
will convert to Class A Shares of the respective Fund after the number of years
set forth herein, in the circumstances and subject to the qualifications
described in this Prospectus. See "Alternative Sales Arrangements" and "Purchase
of Shares."

                               PROSPECTUS SUMMARY
- ------------------------------------------------------------------------------
 
THE FUNDS.  Van Kampen American Capital Insured Tax Free Income Fund (the
"Insured Fund") and Van Kampen American Capital California Insured Tax Free Fund
(the "California Insured Fund") are each separate diversified series of Van
Kampen American Capital Tax Free Trust, an open-end, diversified management
investment company organized as a Delaware business trust (the "Trust"). See
"The Funds."
 
MINIMUM PURCHASE. $500 minimum initial investment for each class of shares and
$25 minimum for each subsequent investment for each class of shares (or less as
described under "Purchase of Shares").
 
INVESTMENT OBJECTIVES.  The INSURED FUND'S investment objective is to provide
investors with a high level of current income exempt from federal income taxes,
with liquidity and safety of principal, primarily through investment in a
diversified portfolio of insured municipal securities.
 
  The CALIFORNIA INSURED FUND'S investment objective is to provide only
California investors with a high level of current income exempt from federal and
California income taxes, with liquidity and safety of principal, primarily
through investment in a diversified portfolio of insured California municipal
securities. THE CALIFORNIA INSURED FUND IS AVAILABLE ONLY TO CALIFORNIA
RESIDENTS. Distribution to corporations subject to the California franchise tax
will be included in such corporation's gross income for purposes of determining
the California franchise tax. In addition, corporations subject to the
California corporate income tax may, in certain circumstances, be subject to
such taxes with respect to distributions from the California Insured Fund.
Accordingly, an investment in shares of the California Insured Fund may not be
appropriate for corporations subject to either tax. See "Tax Status."
 
INVESTMENT POLICIES. Municipal securities in which the Insured Fund and
California Insured Fund (each a "Fund" or collectively the "Funds") may invest
include fixed and variable rate securities, municipal notes, municipal leases,
tax exempt commercial paper, custodial receipts, participation certificates and
derivative municipal securities the terms of which include elements of, or are
similar in effect to, certain Strategic Transactions (as defined herein) in
which the Funds may engage. Each Fund may invest up to 15% of its total assets
in derivative variable rate securities such as inverse floaters, whose rates
vary inversely with changes in market rates of interest or range or capped
floaters, whose rates are subject to periodic or lifetime caps. There is no
assurance that either Fund will achieve its investment objectives. The net asset
value per share of the Funds may increase or decrease depending on changes in
interest rates and other factors affecting the municipal credit markets. See
"Investment Objectives and Policies."
 
INVESTMENT PRACTICES.  In certain circumstances the Funds may enter into when-
issued or delayed delivery transactions and various strategic transactions,
which entail certain risks. See "Municipal Securities" and "Investment
Practices."
 
                                        4
<PAGE>   391
 
INSURANCE.  Each municipal security in the portfolio of the respective Funds is
insured as to the timely payment of principal and interest under one or more
policies obtained by the issuer or purchased by such Fund. No representation is
made as to the ability of any insurer to perform its obligations. See
"Insurance."
 
INVESTMENT RESULTS.  The investment results of the Funds since their inception
are shown in the tables under the captions "Financial Highlights -- Insured
Fund" and "Financial Highlights -- California Insured Fund."
 
ALTERNATIVE SALES ARRANGEMENTS.  The Alternative Sales Arrangements permit an
investor to choose the method of purchasing shares that is more beneficial to
the investor, taking into account the amount of the purchase, the length of time
the investor expects to hold the shares and other circumstances. Investors
should consider such factors together with the amount of sales charges and
accumulated distribution and service fees with respect to each class of shares
that may be incurred over the anticipated duration of their investment in the
Fund. To assist investors in making this determination, the tables under the
captions "Annual Fund Operating Expenses and Examples -- Insured Fund" and
"Annual Fund Operating Expenses and Examples -- California Insured Fund," set
forth examples of the charges applicable to each class of shares.
 
  Each Fund currently offer three classes of shares which may be purchased at a
price equal to their net asset value per share plus sales charges which, at the
election of the investor, may be imposed either (i) at the time of purchase
("Class A Shares") or (ii) on a contingent deferred basis (Class A Share
accounts over $1 million, "Class B Shares" and "Class C Shares"). Class A Share
accounts over $1 million or otherwise subject to a contingent deferred sales
charge ("CDSC"), Class B Shares and Class C Shares sometimes are referred to
herein collectively as "CDSC Shares."
 
  Class A Shares. Class A Shares of the Insured Fund are subject to an initial
sales charge equal to 4.75% of the public offering price (4.99% of the net
amount invested), reduced on investments of $100,000 or more. Class A Shares of
the California Insured Fund are subject to an initial sales charge equal to
3.25% of the public offering price (3.36% of the net amount invested), reduced
on investments of $25,000 or more. Class A Shares are subject to ongoing
distribution and service fees at an aggregate annual rate of up to 0.25% of the
respective Fund's average daily net assets attributable to the Class A Shares.
Certain purchases of Class A Shares qualify for reduced or no initial sales
charges and may be subject to a CDSC.
 
  Class B Shares. Class B Shares do not incur a sales charge when they are
purchased. Class B Shares of the Insured Fund are subject to a CDSC if redeemed
within six years of purchase, which charge is equal to 4.00% of the lesser of
the then current net asset value or the original purchase price of such shares
in the first year after purchase and is reduced each year thereafter. Class B
Shares of the California Insured Fund are subject to a CDSC if redeemed within
four years of purchase, which charge is equal to 3.00% of the lesser of the then
current net asset value or
 
                                        5
<PAGE>   392
 
the original purchase price of such shares in the first year after purchase and
is reduced each year thereafter. Class B Shares are subject to ongoing
distribution and service fees at an aggregate annual rate of up to 1.00% of the
respective Fund's average daily net assets attributable to the Class B Shares.
Class B Shares of the Insured Fund automatically will convert to Class A Shares
of the Insured Fund seven years after the end of the calendar month in which the
investor's order to purchase was accepted. Class B Shares of the California
Insured Fund automatically will convert to Class A Shares of the California
Insured Fund six years after the end of the calendar month in which the
investor's order to purchase was accepted.
 
  Class C Shares. Class C Shares do not incur a sales charge when they are
purchased. Class C Shares are subject to a CDSC equal to 1.00% of the lesser of
the then current net asset value or the original purchase price on Class C
Shares redeemed during the first year after purchase. Class C Shares are subject
to ongoing distribution and service fees at an aggregate annual rate of up to
1.00% of the respective Fund's average daily net assets attributable to the
Class C Shares.
 
REDEMPTION.  Class A Shares may be redeemed at net asset value without charge,
subject to conditions set forth herein. CDSC Shares may be redeemed at net asset
value less a deferred sales charge which will vary between the Funds and among
each class of CDSC Shares and with the length of time a redeeming shareholder
has owned such shares. CDSC Shares redeemed after the expiration of the CDSC
period applicable to the respective class of CDSC Shares will not be subject to
a deferred sales charge. See "Redemption of Shares."
 
INVESTMENT ADVISER.  Van Kampen American Capital Investment Advisory Corp. is
the investment adviser for both of the Funds. See "Investment Advisory
Services."
 
DISTRIBUTOR.  Van Kampen American Capital Distributors, Inc.
 
DISTRIBUTIONS FROM THE FUNDS.  Distributions from net investment income are
declared daily and paid monthly; net realized capital gains, if any, are
distributed annually. Distributions with respect to each class of shares will be
calculated in the same manner and the same day and will be in the same amount
except that the different distribution and service fees and administrative
expenses relating to each class of shares will be borne exclusively by the
respective class. See "Distributions from the Funds."
 
    The above is qualified in its entirety by reference to the more detailed
              information appearing elsewhere in this Prospectus.

- ----------------
(1) The Board of Trustees of the Trust and the shareholders of the Insured Fund
    approved a material change to the investment advisory agreement which
    increased the investment advisory fees effective on August 1, 1995. For the
    year ended December 31, 1994, the Management Fees were (i) 0.42% with
    respect to Class A Shares, (ii) 0.42% with respect to Class B Shares, and
    (iii) 0.42% with respect to Class C Shares and Total Expenses were (i) 0.88%
    with respect to Class A Shares, (ii) 1.71% with respect to Class B Shares
    and (iii) 1.70% with respect to Class C Shares. See "Investment Advisory
    Services." As of June 30, 1995, the Board of Trustees of the Trust reduced
    the 12b-1 and service fees for the Insured Fund's Class A Shares to 0.25%.
    See "The Distribution and Service Fees."
 
(2) Includes a service fee of up to 0.25% (as a percentage of net asset value)
    paid by the Insured Fund as compensation for ongoing services rendered to
    investors. With respect to each class of shares, amounts in excess of 0.25%,
    if any, represent an asset based sales charge. The asset based sales charge
    with respect to Class C Shares includes 0.75% (as a percentage of net asset
    value) paid to investors' brokers, dealers or financial intermediaries as
    sales compensation. See "The Distribution and Service Fees."
 
(3) The Insured Fund's distribution and service plans with respect to Class A
    Shares provide that 12b-1 and service fees are charged only with respect to
    Class A Shares of the Insured Fund sold after the implementation date of
    such plans. Due to the incremental "phase-in" of such plans with respect to
    Class A Shares, it is anticipated that 12b-1 and service fees attributable
    to Class A Shares will increase in accordance with such plans to a maximum
    aggregate amount of 0.25% of the net assets attributable to the Insured
    Fund's Class A Shares. Accordingly, it is unlikely that future expenses will
    remain consistent with those disclosed in the fee table. See "The
    Distribution and Service Plans."

EXAMPLES:
 
  You would pay the following expenses on a $1,000 investment in the Insured
Fund, assuming (i) an operating expense ratio of 0.93% for Class A Shares, 1.80%
for Class B Shares and 1.79% for Class C Shares, (ii) a 5% annual return and
(iii) redemption at the end of each time period. Insured Fund does not charge a
fee for redemptions (other than any applicable contingent deferred sales
charge):

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

(1) Expenses include a waiver of $495,999 of management fees by the Adviser. If
    the Adviser did not waive fees for the fiscal year ending December 31, 1994,
    the "Management Fee" would have been 0.48% and "Total Expenses" would have
    been (i) 1.08% with respect to Class A Shares, (ii) 1.82% with respect to
    Class B Shares and (iii) 1.81% with respect to Class C Shares. See
    "Investment Advisory Services." As of June 30, 1995, the Board of Trustees
    of the Trust reduced the 12b-1 and service fees for the California Insured
    Fund's Class A Shares to 0.25%. See "The Distribution and Service Plans."
 
(2) Includes a service fee of up to 0.25% (as a percentage of net asset value)
    paid by the California Fund as compensation for ongoing services rendered to
    investors. With respect to each class of shares, amounts in excess of 0.25%,
    if any, represent an asset based sales charge. The asset based sales charge
    with respect to Class C Shares includes 0.75% (as a percentage of net asset
    value) paid to investors' broker-dealers as sales compensation. See "The
    Distribution and Service Plans."

* Based on conversion to Class A Shares.
 
  The purpose of the foregoing tables is to assist an investor in understanding
the various costs and expenses that an investor in the California Insured Fund
will bear directly or indirectly. The "Examples" reflect expenses based on the
"Annual Fund Operating Expenses" table as shown above carried out to future
years. Additionally, as the California Insured Fund's assets increase, the fees
waived or expenses reimbursed by the Adviser are expected to decrease.
Accordingly, it is unlikely that future expenses as projected will remain
consistent with those determined based on the table of the "Annual Fund
Operating Expenses." The ten year amount with respect to the Class B Shares of
the California Insured Fund reflects the lower aggregate 12b-1 and service fees
applicable to such shares after conversion to Class A Shares. Class B Shares
acquired through the exchange privilege are subject to the deferred sales charge
schedule relating to the Class B Shares of the fund from which the purchase of
Class B Shares was originally made. Accordingly, future expenses as projected
could be higher than those determined in the above table if the investor's Class
B Shares were exchanged from a fund with a higher contingent deferred sales
charge. THE INFORMATION CONTAINED IN THE ABOVE TABLE SHOULD NOT BE CONSIDERED A

INVESTMENT OBJECTIVES AND POLICIES
- ------------------------------------------------------------------------------
 
  INSURED FUND.  The investment objective of the Insured Fund is to provide
investors with a high level of current income exempt from federal income taxes,
with liquidity and safety of principal, primarily through investment in a
diversified portfolio of insured municipal securities. All of the municipal
securities in the Insured Fund's portfolio, except for investments in tax exempt
money market funds as noted below, will be insured as to timely payment of both
principal and interest. However, there are market risks inherent in all
investments in securities; accordingly there can be no assurance that the
Insured Fund will achieve its objective.
 
  The Insured Fund will generally invest all of its assets in municipal
securities, the interest on which, in the opinion of bond counsel or other
counsel to the issuer of such securities, is exempt from federal income tax. See
"Municipal Securities." From time to time the Insured Fund temporarily may also
invest up to 10% of its assets in tax exempt money market funds. Such
instruments will be treated as investments in municipal securities.
 
  CALIFORNIA INSURED FUND.  The investment objective of the California Insured
Fund is to provide only California investors with a high level of current income
exempt from federal and California income taxes, with liquidity and safety of
principal, primarily through investment in a diversified portfolio of insured
California municipal securities. All of the municipal securities in the
California Insured Fund's portfolio, except for investments in tax exempt money
funds as noted below, will be insured as to timely payment of both principal and
interest. However, there are market risks inherent in all investments in
securities; and accordingly there can be no assurance that the California
Insured Fund will achieve its objective. THE CALIFORNIA INSURED FUND IS
AVAILABLE ONLY TO RESIDENTS OF CALIFORNIA.
 
                                       17

  The California Insured Fund will generally invest all of its assets in
California municipal securities, the interest on which, in the opinion of bond
counsel or other counsel to the issuer of such securities, is exempt from
federal and California income tax. Distribution to corporations subject to the
California franchise tax will be included in such corporation's gross income for
purposes of determining the California franchise tax. In addition, corporations
subject to the California corporate income tax may, in certain circumstances, be
subject to such taxes with respect to distributions from the California Insured
Fund. Accordingly, an investment in shares of the California Insured Fund may
not be appropriate for corporations subject to either tax. See "Municipal
Securities" and "Tax Status." From time to time the California Insured Fund
temporarily may also invest up to 10% of its assets in California tax exempt
money market funds. Such instruments will be treated as investments in municipal
securities.
 
  Investments in the Funds may not be appropriate for all investors. The Funds
are not intended to be a complete investment program, and investors should
consider their long-term investment goals and financial needs when making an
investment decision with respect to the Funds. Investments in the Funds are
intended to be long-term investments and should not be used as trading vehicles.
 
- ------------------------------------------------------------------------------
MUNICIPAL SECURITIES
- ------------------------------------------------------------------------------
 
  GENERAL.  Tax-exempt municipal securities are debt obligations issued by or on
behalf of the governments of states, territories or possessions of the United
States, the District of Columbia and their political subdivisions, agencies and
instrumentalities, certain interstate agencies and certain territories of the
United States, the interest on which, in the opinion of bond counsel or other
counsel to the issuer of such securities, is exempt from federal income tax.
Under normal market conditions, up to 100% but not less than 80%, of each of the
Fund's assets will be invested in such municipal securities. The foregoing is a
fundamental policy of each of the Funds and cannot be changed without approval
of the shareholders of the respective Fund.
 
  The two principal classifications of municipal securities are "general
obligation" and "revenue" securities. "General obligation" securities are
secured by the issuer's pledge of its faith, credit and taxing power for the
payment of principal and interest. "Revenue" securities are usually payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from the proceeds of a special excise tax or other specific
revenue source. Industrial development bonds are usually revenue securities, the
credit quality of which is normally directly related to the credit standing of
the industrial user involved.
 
  Within these principal classifications of municipal securities there are a
variety of categories of municipal securities, including fixed and variable rate
securities, municipal bonds, municipal notes, municipal leases, custodial
receipts, participation certificates and derivative municipal securities the
terms of which include elements
 
                                       18
<PAGE>   405
 
of, or are similar in effect to, certain Strategic Transactions (as defined
below) in which the Funds may engage. Variable rate securities bear rates of
interest that are adjusted periodically according to formulae intended to
reflect market rates of interest and include securities whose rates vary
inversely with changes in market rates of interest. Neither Fund will invest
more than 15% of its total assets in derivative municipal securities such as
inverse floaters, whose rates vary inversely with changes in market rates of
interest, or range floaters or capped floaters whose rates are subject to
periodic or lifetime caps. Such securities may also pay a rate of interest
determined by applying a multiple to the variable rate. The extent of increases
and decreases in the value of securities whose rates vary inversely with market
rates of interest generally will be larger than comparable changes in the value
of an equal principal amount of a fixed rate municipal security having similar
credit quality, redemption provisions and maturity. Municipal notes include tax,
revenue and bond anticipation notes of short maturity, generally less than three
years, which are issued to obtain temporary funds for various public purposes.
Municipal leases are obligations issued by state and local governments or
authorities to finance the acquisition of equipment and facilities. Certain
municipal lease obligations may include "non-appropriation" clauses which
provide that the municipality has no obligation to make lease or installment
purchase payments in future years unless money is appropriated for such purpose
on a yearly basis. Some municipal securities may not be backed by the faith,
credit and taxing power of the issuer. Custodial receipts are underwritten by
securities dealers or banks and evidence ownership of future interest payments,
principal payments or both on certain municipal securities. Participation
certificates are obligations issued by state or local governments or authorities
to finance the acquisition of equipment and facilities. They may represent
participations in a lease, an installment purchase contract or a conditional
sales contract. Some municipal securities may not be backed by the faith, credit
and taxing power of the issuer. Certain of the municipal securities in which the
Funds may invest represent relatively recent innovations in the municipal
securities markets. While markets for such recent innovations progress through
stages of development, such markets may be less developed than more fully
developed markets for municipal securities. A more detailed description of the
types of municipal securities in which the Funds may invest is included in each
Fund's Statement of Additional Information.
 
  The net asset value of each of the Funds will change with changes in the value
of their respective portfolio securities. Because the Funds will invest
primarily in fixed income municipal securities, the net asset value of each of
the Funds can be expected to change as general levels of interest rates
fluctuate. When interest rates decline, the value of a portfolio invested in
fixed income securities generally can be expected to rise. Conversely, when
interest rates rise, the value of a portfolio invested in fixed income
securities generally can be expected to decline. Volatility may be greater
during periods of general economic uncertainty.
 
  From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
municipal
 
                                       19
<PAGE>   406
 
securities. If such a proposal were enacted, the ability of the Funds to pay tax
exempt interest dividends might be adversely affected.
 
  INSURED MUNICIPAL SECURITIES.  With respect to its investments in municipal
securities, each of the Insured Fund and the California Insured Fund may invest
only in municipal securities insured under one of the insurance policies meeting
the standards described in this Prospectus. See "Insurance." Although each
insurer's quality standards may vary from time to time, such insurers generally
insure only those municipal securities that are rated at the date of purchase
(1) in the case of long-term debt, in the four highest ratings by Standard &
Poor's Ratings Group (S&P) (AAA, AA, A and BBB) or by Moody's Investors Service,
Inc. (Moody's) (Aaa, Aa, A and Baa); (2) in the case of short-term notes, SP-1+
through SP-2 by S&P or MIG 1 through MIG 4 by Moody's; or (3) in the case of
tax-exempt commercial paper, A-1+ through A-2 by S&P or Prime-1 through Prime-2
by Moody's. Such ratings are relative and subjective and are not absolute
standards of quality. Any insurer may also insure, and each of the Insured Fund
and California Insured Fund may invest in, unrated municipal securities of
similar quality, as determined by the Adviser, if such securities meet the
insurance standards of such insurer. The Insured Fund and California Insured
Fund may invest, without limitation as to rating category, in any securities for
which such Funds obtain insurance coverage. For a description of such ratings
see the respective Fund's Statement of Additional Information incorporated by
reference into this Prospectus.
 
  SPECIAL CONSIDERATIONS REGARDING CALIFORNIA MUNICIPAL SECURITIES.  Investors
should be aware of certain factors that might affect the financial condition of
the issuers of California municipal securities. With respect to an investment in
the Fund, through popular initiative and legislative activity, the ability of
the State of California (the "State") and its local governments to raise money
through property taxes and to increase spending has been the subject of
considerable debate and change in recent years. Various State Constitutional
amendments, for example, have been adopted which have the effect of limiting
property tax and spending increases, while legislation has sometimes added to
these limitations and has at other times sought to reduce their impact. To date,
these Constitutional, legislative and budget developments do not appear to have
severely decreased the ability of the State and local governments to pay
principal and interest on their obligations. It can be expected that similar
types of State legislation or Constitutional proposals will continue to be
introduced. The impact of future developments in these areas is unclear.
 
  From 1990 until 1994, the State experienced the worst economic, fiscal and
budget conditions since the 1930's. The recession seriously affected State tax
revenues and caused increased expenditures for health and welfare programs. As a
result, the State faced several budget imbalances and used up many of its
available cash resources. Accordingly, rating agencies have reduced the State's
credit ratings several times during recent years.
 
                                       20
<PAGE>   407
 
  Although revenue obligations of the State of California or its political
subdivisions may be payable from a specific project or source, including lease
rentals, there can be no assurance that future economic difficulties and the
resulting impact on State and local government finances will not adversely
affect the market value of the portfolio of the Fund or the ability of the
respective obligors to make timely payments of principal and interest on such
obligations.
 
  More detailed information concerning California municipal securities is
included in the California Insured Fund's Statement of Additional Information.
 
  SELECTION OF INVESTMENTS.  The Adviser will buy and sell securities for each
Fund's portfolio with a view to seeking a high level of current income exempt
from federal income tax and will select securities which the Adviser believes
entail reasonable credit risk considered in relation to the particular
investment policies of such Fund. As a result, the Funds will not necessarily
invest in the highest yielding tax-exempt municipal securities permitted by
their respective investment policies if the Adviser determines that market risks
or credit risks associated with such investments would subject a Fund's
portfolio to excessive risk. The potential for realization of capital gains
resulting from possible changes in interest rates will not be a major
consideration. There is no limitation as to the maturity of municipal securities
in which a Fund may invest. The Adviser may adjust the average maturity of a
Fund's portfolio from time to time, depending on its assessment of the relative
yields available on securities of different maturities and its expectations of
future changes in interest rates. Other than for tax purposes, frequency of
portfolio turnover will generally not be a limiting factor if any of the Funds
considers it advantageous to purchase or sell securities. The Funds may have
annual portfolio turnover rates in excess of 100%. A high rate of portfolio
turnover involves correspondingly greater brokerage commission expenses or
dealer costs than a lower rate, which expenses and costs must be borne by the
respective Fund and its shareholders. High portfolio turnover may also result in
the realization of substantial net short-term capital gains and any
distributions resulting from such gains will be taxable. See "Tax Status."
 
  DEFENSIVE STRATEGIES.  At times conditions in the markets for tax-exempt
municipal securities may, in the Adviser's judgment, make pursuing a Fund's
basic investment strategy inconsistent with the best interests of its
shareholders. At such times, the Adviser may use alternative strategies
primarily designed to reduce fluctuations in the value of such Fund's assets. In
implementing these "defensive" strategies, a Fund may invest to a substantial
degree in high-quality, short-term municipal obligations. If these high-quality,
short-term municipal obligations are not available or, in the Adviser's
judgment, do not afford sufficient protection against adverse market conditions,
such Fund may invest in taxable obligations. Such taxable obligations may
include: obligations of the U.S. Government, its agencies or instrumentalities;
other debt securities rated within the four highest grades by either S&P or
Moody's; commercial paper rated in the highest grade by either rating service;
certificates of deposit and bankers' acceptances; repurchase
 
                                       21
<PAGE>   408
 
agreements with respect to any of the foregoing investments; or any other fixed-
income securities that the Adviser considers consistent with such strategy.
 
- ------------------------------------------------------------------------------
INVESTMENT PRACTICES
- ------------------------------------------------------------------------------
 
  In connection with the investment policies described above, the Funds also may
engage in strategic transactions and purchase and sell securities on a "when
issued" and "delayed delivery" basis. These investments entail risks. Strategic
transactions generally will not be treated as investments in tax-exempt
municipal securities for purposes of the Funds' 80% investment policy with
respect thereto.
 
  STRATEGIC TRANSACTIONS.  The Funds may purchase and sell derivative
instruments such as exchange-listed and over-the-counter put and call options on
securities, financial futures, fixed-income indices and other financial
instruments, purchase and sell financial futures contracts and enter into
various interest rate transactions such as swaps, caps, floors or collars.
Collectively, all of the above are referred to as "Strategic Transactions."
Strategic Transactions may be used to attempt to protect against possible
changes in the market value of securities held in or to be purchased for a
Fund's portfolio resulting from securities markets, to protect such Fund's
unrealized gains in the value of its portfolio securities, to facilitate the
sale of such securities for investment purposes, to manage the effective
maturity or duration of such Fund's portfolio, or to establish a position in the
derivatives markets as a temporary substitute for purchasing or selling
particular securities. Any or all of these investment techniques may be used at
any time and there is no particular strategy that dictates the use of one
technique rather than another, as use of any Strategic Transaction is a function
of numerous variables including market conditions. The ability of a Fund to
utilize these Strategic Transactions successfully will depend on the Adviser's
ability to predict pertinent market movements, which cannot be assured. The
Funds will comply with applicable regulatory requirements when implementing
these strategies, techniques and instruments. Strategic Transactions involving
financial futures and options thereon will be purchased, sold or entered into
only for bona fide hedging, risk management or portfolio management purposes and
not for speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to a
Fund, force the sale of portfolio securities at inopportune times or for prices
other than at current market values, limit the amount of appreciation such Fund
can realize on its investments or cause the Fund to hold a security it might
otherwise sell. The use of options and futures transactions entails certain
other risks. In particular, the variable degree of correlation between price
movements of futures contracts and price movements in the related portfolio
position of a Fund creates the possibility that losses on the hedging instrument
may be greater than gains in the value of such Fund's position. In addition,
futures and
 
                                       22
<PAGE>   409
 
options markets may not be liquid in all circumstances and certain
over-the-counter options may have no markets. As a result, in certain markets, a
Fund might not be able to close out a transaction without incurring substantial
losses, if at all. Although the contemplated use of these futures contracts and
options thereon should tend to minimize the risk of loss due to a decline in the
value of the hedged position, at the same time they tend to limit any potential
gain which might result from an increase in value of such position. Finally, the
daily variation margin requirements for futures contracts would create a greater
ongoing potential financial risk than would purchases of options, where the
exposure is limited to the cost of the initial premium. Losses resulting from
the use of Strategic Transactions would reduce net asset value, and possibly
income, and such losses can be greater than if the Strategic Transactions had
not been utilized. The Strategic Transactions that a Fund may use and some of
their risks are described more fully in the respective Fund's Statement of
Additional Information.
 
  Income earned or deemed to be earned, if any, by a Fund from its Strategic
Transactions will be distributed to its shareholders in taxable distributions.
See "Tax Status."
 
  "WHEN ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS.  The Funds may also
purchase and sell municipal securities on a "when issued" and "delayed delivery"
basis. No income accrues to the Funds on municipal securities in connection with
such purchase transactions prior to the date the Funds actually take delivery of
such securities. These transactions are subject to market fluctuation; the value
of the municipal securities at delivery may be more or less than their purchase
price, and yields generally available on municipal securities when delivery
occurs may be higher or lower than yields on the municipal securities obtained
pursuant to such transactions. Because the Funds rely on the buyer or seller, as
the case may be, to consummate the transaction, failure by the other party to
complete the transaction may result in the Funds missing the opportunity of
obtaining a price or yield considered to be advantageous. When the Funds are the
buyer in such a transaction, however, they will maintain, in a segregated
account with their custodian, cash or high-grade municipal portfolio securities
having an aggregate value equal to the amount of such purchase commitments until
payment is made. The Funds will make commitments to purchase municipal
securities on such basis only with the intention of actually acquiring these
securities, but the Funds may sell such securities prior to the settlement date
if such sale is considered to be advisable. No specific limitation exists as to
the percentage of each Fund's assets which may be used to acquire securities on
a "when issued" or "delayed delivery" basis. To the extent a Fund engages in
"when issued" and "delayed delivery" transactions, they will do so for the
purpose of acquiring securities for the respective Fund's portfolio consistent
with such Fund's respective investment objectives and policies and not for the
purposes of investment leverage. No specific limitation exists as to the
percentage of a Fund's assets which may be used to acquire securities on a "when
issued" or "delayed delivery" basis.
 
                                       23
<PAGE>   410
 
  OTHER PRACTICES. The Funds have no restrictions on the maturity of municipal
bonds in which they may invest. Each Fund will seek to invest in municipal bonds
of such maturities that, in the judgment of such Fund and the Adviser, will
provide a high level of current income consistent with liquidity requirements
and market conditions.
 
  The Funds may borrow amounts up to 5% of their respective net assets in order
to pay for redemptions when liquidation of portfolio securities is considered
disadvantageous or inconvenient and may pledge up to 10% of their respective net
assets to secure such borrowings.
 
  A Fund generally will not invest more than 25% of its total assets in any
industry, nor will a Fund generally invest more than 5% of its assets in the
securities of any single issuer. Governmental issuers of municipal securities
are not considered part of any "industry." However, municipal securities backed
only by the assets and revenues of nongovernmental users may for this purpose be
deemed to be issued by such nongovernmental users, and the 25% limitation would
apply to such obligations. It is nonetheless possible that a Fund may invest
more than 25% of its assets in a broader segment of the municipal securities
market, such as revenue obligations of hospitals and other health care
facilities, housing agency revenue obligations, or airport revenue obligations
if the Advisor determines that the yields available from obligations in a
particular segment of the market justified the additional risks associated with
a large investment in such segment. Although such obligations could be supported
by the credit of governmental users, or by the credit of nongovernmental users
engaged in a number of industries, economic, business, political and other
developments generally affecting the revenues of such users (for example,
proposed legislation or pending court decisions affecting the financing of such
projects and market factors affecting the demand for their services or products)
may have a general adverse effect on all municipal securities in such a market
segment. The Insured Fund reserves the right to invest more than 25% of its
assets in industrial development bonds or in issuers located in the same state,
although it has no present intention to invest more than 25% of its assets in
issuers located in the same state. If the Insured Fund were to invest more than
25% of its assets in issuers located in the same state, it would be more
susceptible to adverse economic, business, or regulatory conditions in that
state. The California Insured Fund invests primarily in a diversified portfolio
of insured California municipal securities.
 
  ALLOCATION OF BROKERAGE TRANSACTIONS. In effecting purchases and sales of the
Funds' portfolio securities, the Adviser and the Funds may place orders with and
pay brokerage commissions to brokers, including brokers which may be affiliated
with the Funds, the Adviser and the Distributor or dealers participating in the
offering of the Funds' shares. In addition, in selecting among firms to handle a
particular transaction, the Adviser and the Funds may take into account whether
the firm has sold or is selling shares of the Funds.

<PAGE>   411
 
- ------------------------------------------------------------------------------
INSURANCE
- ------------------------------------------------------------------------------
 
  All of the municipal securities in the portfolios of the Insured Fund and the
California Insured Fund will be insured by municipal bond insurers whose claims-
paying ability is rated "AAA" by S&P on the date of purchase. Timely payment of
all principal and interest of each municipal security in the portfolios of the
Insured Fund and the California Insured Fund either will be pre-insured under a
policy obtained for such securities prior to the purchase of the securities by
such Funds or will be insured under policies obtained by such Funds to cover
otherwise uninsured securities. With respect to municipal securities that are
not pre-insured, the Insured Fund and the California Insured Fund have each
obtained a mutual fund portfolio insurance policy from AMBAC Indemnity
Corporation ("AMBAC") whose claims-paying ability is rated "AAA" by S&P. The
Insured Fund and the California Insured Fund may obtain portfolio insurance from
other insurers in the future. No representation is made as to any insurer's
ability to meet its commitments.
 
  Each insurance policy guarantees the timely payment of all principal and
interest on the municipal securities. Each policy provides, in general, that in
the event of nonpayment of interest or principal, when due, in respect of an
insured municipal security, the insurer is obligated to make such payment not
later than 30 days after it has been notified by the respective Fund that such
nonpayment has occurred (but not earlier than the date when such payment is
due). For these purposes, a payment of principal is due only at scheduled
maturity, including required sinking fund payments and mandatory redemptions, of
the security and not at any earlier time. The insurance does not guarantee the
market value of the municipal securities or the value of the shares of the
Funds.
 
  More detailed information concerning such insurance policies, and concerning
AMBAC, is included in the respective Fund's Statement of Additional Information.

- ------------------------------------------------------------------------------
ALTERNATIVE SALES ARRANGEMENTS
- ------------------------------------------------------------------------------
 
  The Alternative Sales Arrangements permit an investor to choose the method of
purchasing shares that is more beneficial to the investor, taking into account
the amount of the purchase, the length of time the investor expects to hold the
shares, whether the investor wishes to receive dividends in cash or to reinvest
them in additional shares of the Funds, and other circumstances. Investors
should consider such factors together with the amount of sales charges and
accumulated distribution fees with respect to each class of shares that may be
incurred over the anticipated duration of their investment in the Funds.
 
  Each Fund currently offers three classes of shares, designated Class A Shares,
Class B Shares and Class C Shares. Shares of each class are offered at a price
equal to their net asset value per share plus a sales charge which, at the
election of the purchaser, may be imposed (a) at the time of purchase ("Class A
Shares") or (b) on a contingent deferred basis (Class A Share accounts over $1
million, "Class B Shares" and "Class C Shares"). Class A Share accounts over $1
million or otherwise subject to a contingent deferred sales charge ("CDSC"),
Class B Shares and Class C Shares sometimes are referred to herein collectively
as "Contingent Deferred Sales Charge Shares" or "CDSC Shares."
 
  The minimum initial investment with respect to each class of shares is $500.
The minimum subsequent investment with respect to each class of shares is $25.
It is presently the policy of the Distributor not to accept any order for Class
B Shares or Class C Shares in an amount of $1 million or more because it
ordinarily will be more advantageous for an investor making such an investment
to purchase Class A Shares.
 
  An investor should carefully consider the sales charges applicable to each
class of shares and the estimated period of their investment to determine which
class of shares is more beneficial for the investor to purchase. For example,
investors who would qualify for a significant purchase price discount from the
maximum sales charge on Class A Shares may determine that payment of such a
reduced front-end sales charge is superior to electing to purchase Class B
Shares or Class C Shares, each with no front-end sales charge but subject to a
CDSC and a higher aggregate distribution and service fee. However, because
initial sales charges are deducted at the time of purchase of Class A Share
accounts under $1 million, a purchaser of
 
                                       27
<PAGE>   414
 
such Class A Shares would not have all of his or her funds invested initially
and, therefore, would initially own fewer shares than if Class B Shares or Class
C Shares had been purchased. On the other hand, an investor whose purchase would
not qualify for price discounts applicable to Class A Shares and intends to
remain invested until after the expiration of the applicable CDSC may wish to
defer the sales charge and have all his or her funds initially invested in Class
B Shares or Class C Shares. If such an investor anticipates that he or she will
redeem such shares prior to the expiration of the CDSC period applicable to
Class B Shares, the investor may wish to acquire Class C Shares. Investors must
weigh the benefits of deferring the sales charge and having all of their funds
invested against the higher aggregate distribution and service fee applicable to
Class B Shares and Class C Shares (discussed below). Investors who intend to
hold their shares for a significantly long time may not wish to continue to bear
the ongoing distribution and service expenses of Class C Shares which, in the
aggregate, eventually would exceed the aggregate amount of initial sales charge
and distribution and service expenses applicable to Class A Shares, irrespective
of the fact that a CDSC would eventually not apply to a redemption of Class C
Shares.
 
  Each class of shares represents an interest in the same portfolio of
investments of a Fund and has the same rights, except each class of shares (i)
bears those distribution fees, service fees and administrative expenses
applicable to the respective class of shares as a result of its sales
arrangements, (ii) has exclusive voting rights with respect to those provisions
of the respective Fund's Rule 12b-1 distribution plan which relate only to such
class and (iii) has a different exchange privilege. Only the Class B Shares are
subject to a conversion feature (discussed below). Generally, a class of shares
subject to a higher ongoing distribution fee, service fee or, where applicable,
the conversion feature will have a higher expense ratio and pay lower dividends
than a class of shares subject to a lower ongoing distribution fee, service fee
or not subject to the conversion feature. The per share net asset values of the
different classes of shares are expected to be substantially the same; from time
to time, however, the per share net asset values of the classes may differ. The
net asset value per share of each class of shares of the Funds will be
determined as described in this Prospectus under "Purchase of Shares -- Net
Asset Value."
 
  The administrative expenses that may be allocated to a specific class of
shares will consist of (i) transfer agency expenses attributable to a specific
class of shares, which expenses typically will be higher with respect to classes
of shares subject to the conversion feature; (ii) printing and postage expenses
related to preparing and distributing materials such as shareholder reports,
prospectuses and proxy statements to current shareholders of a specific class;
(iii) Securities and Exchange Commission (the "SEC") registration fees incurred
by a class of shares; (iv) the expense of administrative personnel and services
as required to support the shareholders of a specific class; (v) Trustees' fees
or expense incurred as a result of issues relating to one class of shares; (vi)
accounting expenses relating solely to one class of shares; and (vii) any other
incremental expenses subsequently identified
 
                                       28
<PAGE>   415
 
that should be properly allocated to one or more classes of shares that shall be
approved by the SEC pursuant to an amended exemptive order. All such expenses
incurred by a class will be borne on a pro rata basis by the outstanding shares
of such class. All allocations of administrative expenses to a particular class
of shares will be limited to the extent necessary to preserve the respective
Fund's qualification as a regulated investment company under the Internal
Revenue Code of 1986, as amended (the "Code").
 
- ------------------------------------------------------------------------------
PURCHASE OF SHARES
- ------------------------------------------------------------------------------
 
  Shares of the Funds are continuously offered through Van Kampen American
Capital Distributors, Inc. (the "Distributor"), as principal underwriter, which
is located at One Parkview Plaza, Oakbrook Terrace, Illinois 60181. Shares are
also offered through members of the National Association of Securities Dealers,
Inc. ("NASD") acting as securities dealers ("dealers") and through NASD members
acting as brokers for investors ("brokers") or eligible non-NASD members acting
as agents for investors ("financial intermediaries"). Each of the Funds reserves
the right to suspend or terminate the continuous public offering of its shares
at any time and without prior notice.
 
  The Funds' shares are offered at the net asset value per share next computed
after an investor places an order to purchase directly with the investor's
broker, dealer or financial intermediary or with the Distributor plus any
applicable sales charge. Sales personnel of brokers, dealers and financial
intermediaries distributing the Funds' shares may receive differing compensation
for selling different classes of shares. It is the responsibility of the
investor's broker, dealer or financial intermediary to transmit the order to the
Distributor. Because the Funds generally will determine net asset value once
each business day as of the close of business, purchase orders placed through an
investor's broker, dealer or financial intermediary must be transmitted to the
Distributor by such broker, dealer or financial intermediary prior to such time
in order for the investor's order to be fulfilled on the basis of the net asset
value to be determined that day. Any change in the purchase price due to the
failure of the Distributor to receive a purchase order prior to such time must
be settled between the investor and the broker, dealer or financial intermediary
submitting the order.
 
  The Distributor may from time to time implement programs under which a broker,
dealer or financial intermediary's sales force may be eligible to win nominal
awards for certain sales efforts or under which the Distributor will reallow to
any broker, dealer or financial intermediary that sponsors sales contests or
recognition programs conforming to criteria established by the Distributor, or
participates in sales programs sponsored by the Distributor, an amount not
exceeding the total applicable sales charges on the sales generated by the
broker or dealer at the public offering price during such programs. Other
programs provide, among other things and subject to certain conditions, for
certain favorable distribution arrangements for
 
                                       29
<PAGE>   416
 
shares of the Funds. Also, the Distributor in its discretion may from time to
time, pursuant to objective criteria established by it, pay fees to, and sponsor
business seminars for, qualifying brokers, dealers or financial intermediary for
certain services or activities which are primarily intended to result in sales
of shares of the Funds. Fees may include payment for travel expenses, including
lodging, incurred in connection with trips taken by invited registered
representatives and members of their families to locations within or outside of
the United States for meetings or seminars of a business nature. Such fees paid
for such services and activities with respect to a Fund will not exceed in the
aggregate 1.25% of the average total daily net assets of such Fund on an annual
basis. In addition, the Distributor may provide additional compensation to
Edward D. Jones & Co. ("Edward D. Jones") or an affiliate thereof based on a
combination of its sales of shares and increases in assets under management.
Such payments to brokers, dealers and financial intermediaries for sales
contests, other sales programs and seminars are made by the Distributor out of
its own assets and not out of the assets of the Funds. These programs will not
change the price an investor will pay for shares or the amount that the
respective Fund will receive from such sale.
 
CLASS A SHARES
 
  The public offering price of Class A Shares is equal to the net asset value
per share plus an initial sales charge which is a variable percentage of the
offering price depending upon the amount of the sale. The tables below with
respect to the Funds show total sales charges and dealer concessions reallowed
to dealers and agency commissions paid to brokers with respect to sales of Class
A Shares. The sales charge is allocated between the investor's broker, dealer or
financial intermediary and the Distributor. As indicated previously, at the
discretion of the Distributor, the entire sales charge may be reallowed to such
broker, dealer or financial intermediary. The staff of the SEC has taken the
position that brokers, dealers and financial intermediaries who receive more
than 90% or more of the sales charge may be deemed to be "underwriters" as that
term is defined in the Securities Act of 1933.

* No sales charge is payable at the time of purchase on investments of $1
  million or more, although for such investments the Funds imposes a contingent
  deferred sales charge of 1.00% on redemptions made within one year of the
  purchase. A commission will be paid to dealers who initiate and are
  responsible for purchases of $1 million or more as follows: 1.00% on sales to
  $2 million, plus 0.80% on the next million, plus 0.20% on the next $2 million
  and 0.08% on the excess over $5 million. See "Purchase of Shares -- Deferred
  Sales Charge Alternatives" for additional information with respect to
  contingent deferred sales charges.
 
QUANTITY DISCOUNTS
 
  Investors purchasing Class A Shares may, under certain circumstances, be
entitled to pay reduced sales charges. The circumstances under which such
investors may pay reduced sales charges are described below.
 
  Investors, or their brokers, dealers or financial intermediaries, must notify
the respective Fund whenever a quantity discount is applicable to purchases.
Upon such 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.
 
  As used herein, "any person" eligible for a reduced sales charge includes an
individual, their spouse and minor children (and any trust or custodial accounts
for their benefit) 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 is 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 ("Money Market Fund"), Van Kampen American Capital Tax Free
Money Fund ("Tax Free Money Fund"), Van Kampen American Capital Reserve Fund
("Reserve Fund") and The Govett Funds, Inc.
 
                                       31
<PAGE>   418
 
  VOLUME DISCOUNTS. The size of investment shown in the preceding tables applies
to the total dollar amount being invested by any person at any one time in Class
A Shares of a Fund alone, or in combination with other shares of such 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
tables may also be determined by combining the amount being invested in Class A
Shares of a Fund with other shares of such Fund and shares of Participating
Funds plus the current offering price of all shares of such Fund and other
Participating Funds which have been previously purchased and are still owned.
 
  LETTER OF INTENT. A Letter of Intent provides an opportunity for an investor
to obtain a reduced sales charge by aggregating the amount being invested over a
13-month period to determine the sales charge as outlined in the preceding
tables. The size of investment shown in the preceding table includes the amount
of intended purchases of Class A Shares of a Fund with other shares of such Fund
and shares of the Participating Funds plus the value of all shares of such Fund
and other Participating Funds previously purchased during such 13-month period
and still owned. An investor may elect to compute the 13-month period starting
up to 90 days before the date of execution of a Letter of Intent. Each
investment made during the period receives the reduced sales charge applicable
to the total amount of the investment goal. If trades not initially made under a
Letter of Intent subsequently qualify for a lower sales charge through the
90-day back-dating provision, an adjustment will be made at the expiration of
the Letter of Intent to give effect to the lower charge. If the goal is not
achieved within the 13-month period, the investor must pay the difference
between the charges applicable to the purchases made and the charges previously
paid. When an investor signs a Letter of Intent, shares equal to at least 5% of
the total purchase amount of the level selected will be restricted from sale or
redemption by the investor until the Letter of Intent is satisfied or any
additional sales charges have been paid; if the Letter of Intent is not
satisfied by the investor and any additional sales charges are not paid,
sufficient restricted shares will be redeemed by the Fund to pay such charges.
Additional information is contained in the application accompanying this
Prospectus.
 
OTHER PURCHASE PROGRAMS
 
  Purchasers of Class A Shares may be entitled to reduced initial sales charges
in connection with unit trust reinvestment programs and purchases by registered
representatives of selling firms or purchases by persons affiliated with the
respective Fund or the Distributor. The Funds reserve the right to modify or
terminate these arrangements at any time.
 
                                       32
<PAGE>   419
 
  UNIT TRUST REINVESTMENT PROGRAMS. Each of the Funds permits unitholders of
unit investment trusts to reinvest distributions from such trusts in Class A
Shares of such Fund 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 such Fund and the Distributor. The total sales charge for all
investments made from unit trust distributions will be 1.00% of the offering
price (1.01% of net asset value). Of this amount, the Distributor will pay to
the broker, dealer or financial intermediary, if any, through which such
participation in the qualifying program was initiated 0.50% of the offering
price as a dealer concession or agency commission. Persons desiring more
information with respect to this program, including the applicable terms and
conditions thereof, should contact their broker, dealer or financial
intermediary or the Distributor.
 
  The administrator of such a unit investment trust must have an agreement with
the Distributor pursuant to which the administrator will (1) submit a single
bulk order and make payment with a single remittance for all investments in the
respective Fund during each distribution period by all investors who choose to
invest in such Fund through the program and (2) provide such Fund's transfer
agent with appropriate backup data for each participating investor in a
computerized format fully compatible with the transfer agent's processing
system.
 
  As further requirements for obtaining these special benefits, the respective
Fund also requires that all dividends and other distributions by such Fund be
reinvested in additional shares without any systematic withdrawal program. There
will be no minimum for reinvestments from unit investment trusts. The Fund will
send account activity statements to such participants on a monthly basis only,
even if their investments are made more frequently.
 
  NAV PURCHASE OPTIONS. Class A Shares of a 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 such Fund,
by:
 
  (1) Current or retired Trustees/Directors of funds advised by the Adviser, Van
      Kampen American Capital Asset Management, Inc. or John Govett & Co.
      Limited and such persons' families and their beneficial accounts.
 
  (2) Current or retired directors, officers and employees of VK/AC Holding,
      Inc. and any of its subsidiaries, Clayton, Dubilier & Rice, Inc.,
      employees of an investment subadviser to any fund described in (1) above
      or an affiliate of such subadviser; and such persons' families and their
      beneficial accounts.
 
  (3) Directors, officers, employees and registered representatives of financial
      institutions that have a selling group agreement with the Distributor and
      their spouses and minor children when purchasing for any accounts they
      beneficially own, or, in the case of any such financial institution, when
      purchasing for retirement plans for such institution's employees.

<PAGE>   420
 
  (4) Registered investment advisers, trust companies and bank trust departments
      investing on their own behalf or on behalf of their clients provided that
      the aggregate amount invested in Class A Shares of a Fund alone, or in any
      combination of shares of such Fund and shares of other Participating Funds
      as described herein under "Purchase of Shares -- Class A Shares --
      Quantity Discounts," during the 13-month period commencing with the first
      investment pursuant hereto equals at least $1 million. The Distributor may
      pay brokers, dealers or financial intermediaries through which purchases
      are made an amount up to 0.50% of the amount invested, over a twelve-month
      period following such transaction.
 
  (5) Trustees and other fiduciaries purchasing shares for retirement plans of
      organizations with retirement plan assets of $10 million or more. The
      Distributor may pay commissions of up to 1.00% for such purchases.
 
  (6) Accounts as to which a broker, dealer or financial intermediary charges an
      account management fee ("wrap accounts"), provided the broker, dealer or
      financial intermediary has a separate agreement with the Distributor.
 
  (7) Investors purchasing shares of a Fund with redemption proceeds from other
      mutual fund complexes on which the investor has paid a front-end sales
      charge or was subject to a deferred sales charge, whether or not paid, if
      such redemption has occurred no more than 30 days prior to such purchase.
 
  (8) Full service participant directed profit sharing and money purchase plans,
      full service 401(k) plans, or similar full service recordkeeping programs
      made available through Van Kampen American Capital Trust Company with at
      least 50 eligible employees or investing at least $250,000 in the
      Participating Funds, Money Market Fund, Tax Free Money Fund or Reserve
      Fund. For such investments the respective Fund imposes a contingent
      deferred sales charge of 1.00% in the event of redemptions within one year
      of the purchase other than redemptions required to make payments to
      participants under the terms of the plan. The contingent deferred sales
      charge incurred upon certain redemptions is paid to the Distributor in
      reimbursement for distribution-related expenses. A commission will be paid
      to dealers who initiate and are responsible for such purchases as follows:
      1.00% on sales to $5 million, plus 0.50% on the next $5 million, plus
      0.25% on the excess over $10 million.
 
The term "families" includes a person's spouse, minor children and
grandchildren, parents, and a person's spouse's parents.
 
  Purchase orders made pursuant to clause (4) may be placed either through
authorized brokers, dealers or financial intermediaries as described above or
directly with the respective Fund's transfer agent, the investment adviser,
trust company or bank trust department, provided that such Fund's transfer agent
receives federal funds for the purchase by the close of business on the next
business day following acceptance of the order. An authorized broker, dealer or
financial intermediary may
 
                                       34
<PAGE>   421
 
charge a transaction fee for placing an order to purchase shares pursuant to
this provision or for placing a redemption order with respect to such shares.
The Funds may terminate, or amend the terms of, offering shares of the Funds at
net asset value to such groups at any time.
 
DEFERRED SALES CHARGE ALTERNATIVES
 
  Investors choosing the deferred sales charge alternative may purchase Class A
Shares in an amount of $1 million or more, Class B Shares or Class C Shares. The
public offering price of a CDSC Share is equal to the net asset value per share
without the imposition of a sales charge at the time of purchase. CDSC Shares
are sold without an initial sales charge so that the Funds may invest the full
amount of the investor's purchase payment. The Distributor will compensate
brokers, dealers and financial intermediaries participating in the continuous
public offering of the CDSC Shares out of its own assets, and not out of the
assets of the respective Fund, at a percentage rate of the dollar value of the
CDSC Shares purchased from such Fund by such brokers, dealers and financial
intermediaries, which percentage rate will be equal to (i) with respect to Class
A Shares, 1.00% on sales to $2 million, plus 0.80% on the next million, plus
0.20% on the next $2 million and 0.08% on the excess over $5 million; (ii) 4.00%
with respect to Class B Shares of the Insured Fund; (iii) 3.00% with respect to
Class B Shares of the California Insured Fund; and (iv) 1.00% with respect to
Class C Shares of each Fund. Such compensation will not change the price an
investor will pay for CDSC Shares or the amount that the respective Fund will
receive from such sale.
 
  CDSC Shares redeemed within a specified period of time generally will be
subject to a contingent deferred sales charge at the rates set forth below. The
amount of the contingent deferred sales charge will vary depending on (i) the
class of CDSC Shares to which such shares belong and (ii) the number of years
from the time of payment for the purchase of the CDSC Shares until the time of
their redemption. The charge will be assessed on an amount equal to the lesser
of the then current market value or the original purchase price of the CDSC
Shares being redeemed. Accordingly, no sales charge will be imposed on increases
in net asset value above the initial purchase price. In addition, no contingent
deferred sales charge will be assessed on CDSC Shares derived from reinvestment
of dividends or capital gains distributions. Solely for purposes of determining
the number of years from the time of any payment for the purchase of CDSC
Shares, all payments during a month will be aggregated and deemed to have been
made on the last day of the month.
 
  Proceeds from the contingent deferred sales charge applicable to a class of
CDSC Shares are paid to the Distributor and are used by the Distributor to
defray its expenses related to providing distribution related services to the
respective Fund in connection with the sale of shares of such class of CDSC
Shares, such as the payment of compensation to selected dealers and agents for
selling such shares. The combination of the contingent deferred sales charge and
the distribution and
 
                                       35
<PAGE>   422
 
services fees facilitates the ability of the respective Fund to sell such CDSC
Shares without a sales charge being deducted at the time of purchase.
 
  In determining whether a contingent deferred sales charge is applicable to a
redemption of CDSC Shares, it will be assumed that the redemption is made first
of any CDSC Shares acquired pursuant to reinvestment of dividends or
distributions, second of CDSC Shares that have been held for a sufficient period
of time such that the contingent deferred sales charge no longer is applicable
to such shares, third of Class A Shares in the shareholder's Fund account that
have converted from Class B Shares, if any, and fourth of CDSC Shares held
longest during the period of time that a contingent deferred sales charge is
applicable to such CDSC Shares. The charge will not be applied to dollar amounts
representing an increase in the net asset value per share since the time of
purchase.
 
  To provide an example, assume an investor purchased 100 Class B Shares of the
Insured Fund (as set forth below) at $10 per share (at a cost of $1,000) and in
the second year after purchase, the net asset value per share is $12 and, during
such time, the investor has acquired 10 additional Class B Shares upon dividend
reinvestment. If at such time the investor makes his first redemption of 50
shares (proceeds of $600), 10 shares will not be subject to charge because of
dividend reinvestment. With respect to the remaining 40 shares, the charge is
applied only to the original cost of $10 per share and not to the increase in
net asset value of $2 per share. Therefore, $400 of the $600 redemption proceeds
will be charged at a rate of 3.75% (the applicable rate in the second year after
purchase).
 
  CLASS A SHARE PURCHASES OF $1 MILLION OR MORE. No sales charge is payable at
the time of purchase on investments in Class A Shares of $1 million or more,
although for such investments the respective Fund may impose a contingent
deferred sales charge of 1.00% on redemptions made within one year of the
purchase. A commission will be paid to dealers who initiate and are responsible
for purchases of $1 million or more as follows: 1.00% on sales to $2 million,
plus 0.80% on the next million, plus 0.20% on the next $2 million and 0.08% on
the excess over $5 million.
 
  CLASS B SHARES. Class B Shares redeemed within the number of years of purchase
set forth below generally will be subject to a contingent deferred sales
 
                                       36
<PAGE>   423
 
charge at the rates set forth below, charged as a percentage of the dollar
amount subject thereto:

  The contingent deferred sales charge generally is waived on redemptions of
Class B Shares made pursuant to the Systematic Withdrawal Plan. See "Shareholder
Services -- Systematic Withdrawal Plan."
 
  Conversion Feature. Class B Shares of the Insured Fund automatically will
convert to Class A Shares of the Insured Fund seven years after the end of the
month in which a shareholder's order to purchase such Class B Shares was
accepted and thereafter will be subject to the lower aggregate distribution and
service fees applicable to Class A Shares of the Insured Fund. Class B Shares of
the California Insured Fund automatically will convert to Class A Shares of the
California Insured Fund six years after the end of the month in which a
shareholder's order to purchase such Class B Shares was accepted and thereafter
will be subject to the lower aggregate distribution and service fees applicable
to Class A Shares of the California Insured Fund. The purpose of the conversion
feature is to relieve the holders of Class B Shares that have been outstanding
for a period of time sufficient
 
                                       37
<PAGE>   424
 
for the Distributor to have been compensated for distribution expenses related
to the Class B Shares from most of the burden of such distribution-related
expenses.
 
  For purposes of conversion to Class A Shares, Class B Shares purchased through
the reinvestment of dividends and distributions paid in respect of Class B
Shares in a shareholder's account will be considered to be held in a separate
sub-account. Each time any Class B Shares in the shareholder's account (other
than those in the sub-account) convert to Class A Shares, an equal pro rata
portion of the Class B Shares in the sub-account also will convert to Class A
Shares. The holding period applicable to a Class B Share acquired through the
use of the exchange privilege (discussed below) shall be the holding period
applicable to a Class B Share of such Fund acquired other than through use of
the exchange privilege. For purposes of calculating the holding period
applicable to a Class B Share of a Fund prior to conversion, a Class B Share of
such Fund issued in connection with an exercise of the exchange privilege, or a
series of exchanges, shall be deemed to have been issued on the date on which
the investor's order to purchase the exchanged Class B Share was accepted or, in
the case of a series of exchanges, when the investor's order to purchase the
original Class B Share was accepted.
 
  The conversion of Class B Shares to Class A Shares is subject to the
continuing availability of an opinion of counsel to the effect that (i) the
assessment of the higher distribution services fee and transfer agency costs
with respect to Class B Shares does not result in a Fund's dividends or
distributions constituting "preferential dividends" under the Code and (ii) that
the conversion of Class B Shares does not constitute a taxable event under
federal income tax law. The conversion of Class B Shares to Class A Shares may
be suspended if such an opinion is no longer available. In that event, no
further conversions of Class B Shares would occur, and Class B Shares might
continue to be subject to the higher aggregate distribution and service fees for
an indefinite period.
 
  CLASS C SHARES. Class C Shares of each Fund redeemed within the first twelve
months of purchase generally will be subject to a contingent deferred sales
charge of 1.00% of the dollar amount subject thereto. Class C Shares redeemed
thereafter will not be subject to a contingent deferred sales charge. Class C
Shares of each Fund do not convert to Class A Shares.
 
  WAIVER OF CONTINGENT DEFERRED SALES CHARGE.  The contingent deferred sales
charge is waived on redemptions of Class B Shares and Class C Shares (i)
following the death or disability (as defined in the Code) of a shareholder,
(ii) in connection with 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 "Shareholder
 
                                       38
<PAGE>   425
 
Services" and "Redemption of Shares" for further discussion of the waiver
provisions.
 
NET ASSET VALUE
 
  The net asset value per share of each of the Funds is determined by
calculating the total value of such Fund's assets, deducting its total
liabilities, and dividing the result by the number of shares of such Fund
outstanding. The net asset value is computed once daily as of 5:00 p.m. Eastern
time, Monday through Friday, except on customary business holidays, or except on
any day on which no purchase or redemption orders are received, or there is not
a sufficient degree of trading in such Fund's portfolio securities such that the
Fund's net asset value per share might be materially affected. Each of the Funds
reserves the right to calculate the net asset value and to adjust the public
offering price based thereon more frequently than once a day if deemed
desirable.
 
  Fixed income securities are valued by using market quotations, prices provided
by market makers or estimates of market values obtained from yield data relating
to instruments or securities with similar characteristics in accordance with
procedures established in good faith by the Trustees of the Trust, of which each
Fund is a separate series. Short-term securities with remaining maturities of
less than 60 days are valued at amortized cost when amortized cost is determined
in good faith by or under the direction of the Board of Trustees of the Trust to
be representative of the fair value at which it is expected such securities may
be resold. Other assets are valued at fair value as determined in good faith by
or under direction of the Trustees. The net asset values per share of the
different classes of shares are expected to be substantially the same; from time
to time, however, the per share net asset value of the different classes of
shares may differ.
 
- ------------------------------------------------------------------------------
SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------
 
  Each of the Funds offers a number of shareholder services designed to
facilitate investment in its shares at little or no extra cost to the investor.
Below is a description of such services. Unless otherwise described below, each
of these services may be modified or terminated by the respective Fund at any
time.
 
SHAREHOLDER SERVICES APPLICABLE TO ALL CLASSES
 
  INVESTMENT ACCOUNT. ACCESS Investor Services, Inc. ("ACCESS"), transfer agent
for the Funds and a wholly-owned subsidiary of Van Kampen American Capital,
performs bookkeeping, data processing and administration services related to the
maintenance of shareholder accounts. Each shareholder has an investment account
under which shares are held by ACCESS. Except as described herein, after each
share transaction in an account, the shareholder receives a statement showing
 
                                       39
<PAGE>   426
 
the activity in the account. Each shareholder will receive statements at least
quarterly from ACCESS showing any reinvestments of dividends and capital gains
distributions and any other activity in the account since the preceding
statement. Such shareholders also will receive separate confirmations for each
purchase or sale transaction other than reinvestment of dividends and capital
gains distributions and systematic purchases or redemptions. Additions to an
investment account may be made at any time by purchasing shares through
authorized brokers, dealers or financial intermediaries or by mailing a check
directly to ACCESS.
 
  SHARE CERTIFICATES. Generally, the Funds will not issue share certificates.
However, upon written or telephone request to the respective Fund, a share
certificate will be issued, representing shares (with the exception of
fractional shares) of such Fund. A shareholder will be required to surrender
such certificates upon redemption thereof. In addition, if such certificates are
lost the shareholder must write to Van Kampen American Capital Funds, c/o
ACCESS, P.O. Box 418256, Kansas City, MO 64141-9256, requesting an "affidavit of
loss" and to obtain a Surety Bond in a form acceptable to ACCESS. On the date
the letter is received ACCESS will calculate a fee for replacing the lost
certificate equal to no more than 2.00% of the net asset value of the issued
shares and bill the party to whom the replacement certificate was mailed.
 
  REINVESTMENT PLAN. A convenient way for investors to accumulate additional
shares is by accepting dividends and capital gains distributions in shares of
the respective Fund. Such shares are acquired at net asset value (without sales
charge) on the record date of such dividend or distribution. Unless the
shareholder instructs otherwise, the reinvestment plan is automatic. This
instruction may be made by telephone by calling (800) 421-5666 ((800) 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. For further
information, see "Distributions from the Funds."
 
  AUTOMATIC INVESTMENT PLAN. An automatic investment plan is available under
which a shareholder can authorize ACCESS to charge a bank account on a regular
basis to invest pre-determined amounts in the respective Fund. Additional
information is available from the Distributor or authorized brokers, dealers or
financial intermediaries.
 
  DIVIDEND DIVERSIFICATION. A shareholder may, upon written request or by
completing the appropriate section of the application form accompanied by this
Prospectus or by calling (800) 421-5666 ((800) 772-8889 for the hearing
impaired), elect to have all dividends and other distributions paid on a class
of shares of the respective Fund invested into shares of the same class of any
other Participating Fund, Money Market Fund, Tax Free Money Fund or Reserve Fund
so long as a pre-existing account for such class of shares exists for such
shareholder.
 
                                       40
<PAGE>   427
 
  If the qualified pre-existing account does not exist, the shareholder must
establish a new account subject to minimum investment and other requirements of
the fund into which distributions would be invested. Distributions are invested
into the selected fund at its net asset value as of the payable date of the
distribution only if shares of such selected fund have been registered for sale
in the investor's state.
 
  EXCHANGE PRIVILEGE. Shares of a Fund may be exchanged with shares of another
Participating Fund, the Money Market Fund, the Tax Free Money Fund or the
Reserve Fund, subject to certain limitations herein or in such other fund's
prospectus. Before effecting an exchange, shareholders in the Fund should obtain
and read a current prospectus of the fund into which the exchange is to be made.
SHAREHOLDERS MAY ONLY EXCHANGE INTO SUCH OTHER FUNDS AS ARE LEGALLY AVAILABLE
FOR SALE IN THEIR STATE.
 
  In general, shares of a Fund must have been registered in the shareholder's
name for at least 15 days prior to an exchange. Shares of a Fund registered in a
shareholder's name for less than 15 days may only be exchanged upon receipt of
prior approval of the Adviser; however, under normal circumstances, it is the
policy of the Adviser not to approve such requests. Upon 60 days after the date
of this prospectus, each of the Funds will increase the number of days shares
must be registered in a shareholder's name prior to an exchange to 30 days.
 
  Exchanges of Class A Shares of a Fund that have been charged a sales charge
lower than the sales charge applicable to the other fund will have the sales
charge differential imposed upon the exchange into such fund. Similarly,
exchanges of any Class A Shares of other funds that have been charged a sales
charge lower than the sales charge applicable to a Fund will have the sales
charge differential imposed upon exchange into such Fund. Shares of other funds
which have not previously been charged a sales charge (except for shares
purchased via the reinvestment option) will be charged the sales charge
differential applicable to Class A Shares of a Fund upon exchange into such
Fund.
 
  No sales charge is imposed upon the exchange of Class B Shares and Class C
Shares. Upon redemption of Class B Shares and Class C Shares from the Van Kampen
American Capital family of funds, Class B Shares and Class C Shares which have
been exchanged are subject to the contingent deferred sales charge imposed by
the initial Van Kampen American Capital fund purchased by the investor prior to
any exchanges. The holding period requirements for the contingent deferred sales
charge, and the conversion privilege for Class B Shares of a Fund, are
determined by the date of purchase into the initial Van Kampen American Capital
fund purchased by the investor prior to any exchanges.
 
  Exchanges of shares are sales and may result in a gain or loss for federal
income tax purposes. If the shares exchanged have been held for less than 91
days, the sales charge paid on such shares is not included in the tax basis of
the exchanged shares, but is carried over and included in the tax basis of the
shares acquired.
 
                                       41
<PAGE>   428
 
  A shareholder wishing to make an exchange may do so by sending a written
request to ACCESS or by contacting the telephone transaction line at (800)
421-5684 ((800) 772-8889 for the hearing impaired). A shareholder automatically
has telephone exchange privileges unless otherwise designated in the application
form accompanied by this Prospectus. The exchange will take place at the
relative net asset values of the shares next determined after receipt of such
request with adjustment for any additional sales charge. Any shares exchanged
begin earning dividends on the next business day after the exchange is affected.
Van Kampen American Capital and its subsidiaries, including ACCESS
(collectively, "VKAC"), and the Funds employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications, and providing written confirmation of instructions communicated
by telephone. If reasonable procedures are employed, a shareholder agrees that
neither VKAC nor the respective Fund will be liable for following telephone
instructions which it reasonably believes to be genuine. VKAC and the respective
Fund may be liable for any losses due to unauthorized or fraudulent instructions
if reasonable procedures are not followed. If the exchanging shareholder does
not have an account in the fund whose shares are being acquired, a new account
will be established with the same registration, dividend and capital gains
options (except dividend diversification options) and broker, dealer or
financial intermediary of record as the account from which shares are exchanged,
unless otherwise specified by the shareholder. In order to establish a
systematic withdrawal plan for the new account or dividend diversification
options for the new account, an exchanging shareholder must file a specific
written request. Each of the Funds reserves the right to reject any order to
acquire its shares through exchange. In addition, each of the Funds may restrict
or terminate the exchange privilege at any time on 60 days' notice to its
shareholders of any termination or material amendment.
 
  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 taxable gain or loss will be
recognized. The plan holder may arrange for monthly, quarterly, semi-annual, or
annual checks in any amount not less than $25.
 
  Holders of Class B Shares and Class C Shares who establish a withdrawal plan
may redeem up to 12% annually of the shareholder's initial account balance
without incurring a contingent deferred sales charge. Initial account balance
means the amount of the shareholder's investment in the respective Fund at the
time the election to participate in the plan is made. See "Purchase of
Shares -- Deferred Sales Charge Alternatives -- Waiver of Contingent Deferred
Sales Charge."
 
                                       42
<PAGE>   429
 
  Under the plan, sufficient shares of a Fund are redeemed to provide the amount
of the periodic withdrawal payment. Dividends and capital gains distributions on
shares held under the plan are reinvested in additional shares at the next
determined net asset value. If periodic withdrawals continuously exceed
reinvested dividends and capital gains distributions, the shareholder's original
investment will be correspondingly reduced and ultimately exhausted. Withdrawals
made concurrently with purchases of additional shares ordinarily will be
disadvantageous to the shareholder because of the duplication of sales charges.
Each of the Funds reserves the right to amend or terminate the systematic
withdrawal program on thirty days' notice to its shareholders.
 
SHAREHOLDER SERVICES APPLICABLE TO CLASS A SHAREHOLDERS ONLY
 
  CHECK WRITING PRIVILEGE. Holders of Class A Shares of the Funds for which
certificates have not been issued and which are in a non-escrow status may
appoint ACCESS as agent by completing the Authorization for Redemption by Check
Form and the appropriate section of the application and returning the form and
the application to ACCESS. Once the form is properly completed, signed and
returned to the agent, a supply of checks drawn on State Street Bank and Trust
Company ("State Street Bank") will be sent to such shareholder. These checks may
be made payable by the holder of Class A Shares to the order of any person in
any amount of $100 or more.
 
  When a check is presented to State Street Bank for payment, full and
fractional Class A Shares required to cover the amount of the check are redeemed
from the shareholder's account by ACCESS at the next determined net asset value.
Check writing redemptions represent the sale of Class A Shares. Any gain or loss
realized on the sale of Class A Shares is a taxable event. See "Redemption of
Shares."
 
  Checks will not be honored for redemption of Class A Shares held less than 15
calendar days, unless such Class A Shares have been paid for by bank wire. Any
Class A Shares for which there are outstanding certificates may not be redeemed
by check. If the amount of the check is greater than the proceeds of all
uncertificated shares held in the shareholder's Class A Share account, the check
will be returned and the shareholder may be subject to additional charges.
Holders of Class A Shares may not liquidate the entire account by means of a
check. The check writing privilege may be terminated or suspended at any time by
the respective Fund or State Street Bank. Retirement plans and accounts that are
subject to backup withholding are not eligible for the privilege. A "stop
payment" system is not available on these checks.
 
  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
 
                                       43
<PAGE>   430
 
of Automated Clearing House. In addition, the shareholder must fill out the
appropriate section of the account application. The shareholder must also
include a voided check or deposit slip from the bank account into which
redemptions are to be deposited together with the completed application. Once
ACCESS has received the application and the voided check or deposit slip, such
shareholder's designated bank account, following any redemption, will be
credited with the proceeds of such redemption. Once enrolled in the ACH plan, a
shareholder may terminate participation at any time by writing ACCESS.
 
- ------------------------------------------------------------------------------
REDEMPTION OF SHARES
- ------------------------------------------------------------------------------
 
  Shareholders may redeem for cash some or all of their shares without charge by
the respective Fund (other than, with respect to CDSC Shares, the applicable
contingent deferred sales charge) at any time by sending a written request in
proper form directly to ACCESS, P. O. Box 418256, Kansas City, Missouri
64141-9256, by placing the redemption request through an authorized dealer or by
calling the respective Fund.
 
  WRITTEN REDEMPTION REQUESTS. In the case of redemption requests sent directly
to ACCESS, the redemption request should indicate the number of shares to be
redeemed, the class designation of such shares, the account number and be signed
exactly as the shares are registered. Signatures must conform exactly to the
account registration. If the proceeds of the redemption would exceed $50,000, or
if the proceeds are not to be paid to the record owner at the record address, or
if the record address has changed within the previous 30 days, signature(s) must
be guaranteed by one of the following: a bank or trust company; a broker-dealer;
a credit union; a national securities exchange, registered securities
association or clearing agency; a savings and loan association; or a federal
savings bank. If certificates are held for the shares being redeemed, such
certificates must be endorsed for transfer or accompanied by an endorsed stock
power and sent with the redemption request. In the event the redemption is
requested by a corporation, partnership, trust, fiduciary, executor or
administrator, and the name and title of the individual(s) authorizing such
redemption is not shown in the account registration, a copy of the corporate
resolution or other legal documentation appointing the authorized signer and
certified within the prior 60 days must accompany the redemption request. The
redemption price is the net asset value per share next determined after the
request is received by ACCESS in proper form. Payment for shares redeemed (less
any sales charge, if applicable) will ordinarily be made by check mailed within
three business days after acceptance by ACCESS of the request and any other
necessary documents in proper order. Such payments may be postponed or the right
of redemption suspended as provided by the rules of the SEC. If the shares to be
redeemed have been recently purchased by check, ACCESS may delay mailing a
redemption check until it confirms that the purchase check has cleared, usually
a period of up to 15 days. Any gain or loss realized on the redemption of shares
is a taxable event.
 
                                       44
<PAGE>   431
 
  DEALER REDEMPTION REQUESTS. Shareholders may sell shares through their
securities dealer, who will telephone the request to the Distributor. Orders
received from dealers must be at least $500 unless transmitted via the FUNDSERV
network. The redemption price for such shares is the net asset value next
calculated after an order is received by a dealer provided such order is
transmitted to the Distributor prior to the Distributor's close of business on
such day. It is the responsibility of dealers to transmit redemption requests
received by them to the Distributor so they will be received prior to such time.
Any change in the redemption price due to failure of the Distributor to receive
a sell order prior to such time must be settled between the shareholder and
dealer. Shareholders must submit a written redemption request in proper form (as
described above under "Written Redemption Requests") to the dealer within three
business days after calling the dealer with the sell order. Payment for shares
redeemed (less any sales charge, if applicable) will ordinarily be made by check
mailed within three business days to the dealer.
 
  TELEPHONE REDEMPTION REQUESTS. Each of the Funds permits redemption of shares
by telephone and for redemption proceeds to be sent to the address of record for
the account or to the bank account of record as described below. To establish
such privilege, a shareholder must complete the appropriate section of the
application form accompanying this Prospectus or call the respective Fund at
(800) 421-5666 ((800) 772-8889 for the hearing impaired) to request that a copy
of the Telephone Redemption Authorization form be sent to them for completion.
To redeem shares, contact the telephone transaction line at (800) 421-5684. VKAC
and the Funds employ procedures considered by them to be reasonable to confirm
that instructions communicated by telephone are genuine. Such procedures include
requiring certain personal identification information prior to acting upon
telephone instructions, tape recording telephone communications, and providing
written confirmation of instructions communicated by telephone. If reasonable
procedures are employed, a shareholder agrees that neither VKAC nor the
respective Fund will be liable for following instructions which it reasonably
believes to be genuine. VKAC and the respective Fund may be liable for any
losses due to unauthorized or fraudulent instructions if reasonable procedures
are not followed. Telephone redemptions may not be available if the shareholder
cannot reach ACCESS by telephone, whether because all telephone lines are busy
or for any other reason; in such case, a shareholder would have to use the
respective Fund's other redemption procedures previously described. Requests
received by ACCESS prior to 4:00 p.m., New York time, on a regular business day
will be processed at the net asset value per share determined that day. These
privileges are available for all accounts other than retirement accounts. The
telephone redemption privilege is not available for shares represented by
certificates. If the shares to be redeemed have been recently purchased by
check, ACCESS may delay mailing a redemption check or wiring redemption proceeds
until it confirms that the purchase check has cleared, usually a period of up to
15 days. If an account has multiple owners, ACCESS may rely on the instructions
of any one owner.

  For redemptions authorized by telephone, amounts of $50,000 or less may be
redeemed daily if the proceeds are to be paid by check sent to the shareholders'
address of record and amounts of at least $1,000 and up to $1 million may be
redeemed daily if the proceeds are to be paid by wire sent to the shareholder's
bank account of record. The proceeds must be payable to the shareholder(s) of
record. Proceeds from redemptions to be paid by check will ordinarily be mailed
within three business days to the shareholder's address of record. Proceeds from
redemptions to be paid by wire will ordinarily be wired on the next business day
to the shareholder's bank account of record. This privilege is not available if
the address of record has been changed within 30 days prior to a telephone
redemption request. Each of the Funds reserves the right at any time to
terminate, limit or otherwise modify this telephone redemption privilege.
 
  REDEMPTION UPON DISABILITY. The Funds will waive the contingent deferred sales
charge on redemptions following the disability of holders of Class B Shares and
Class C Shares. An individual will be considered disabled for this purpose if he
or she meets the definition thereof in Section 72(m)(7) of the Code, which in
pertinent part defines a person as disabled if such person "is unable to engage
in any substantial gainful activity by reason of any medically determinable
physical or mental impairment which can be expected to result in death or to be
of long-continued and indefinite duration." While the Funds do not specifically
adopt the balance of the Code's definition which pertains to furnishing the
Secretary of Treasury with such proof as he or she may require, the Distributor
will require satisfactory proof of disability before it determines to waive the
contingent deferred sales charge on Class B Shares and Class C Shares.
 
  In cases of disability, the contingent deferred sales charges on Class B
Shares and Class C Shares will be waived where the disabled person is either an
individual shareholder or owns the shares as a joint tenant with right of
survivorship or is the beneficial owner of a custodial or fiduciary account, and
where the redemption is made within one year of the initial determination of
disability. This waiver of the contingent deferred sales charge on Class B
Shares and Class C Shares applies to a total or partial redemption, but only to
redemptions of shares held at the time of the initial determination of
disability.
 
  GENERAL REDEMPTION INFORMATION. The respective Fund may redeem any shareholder
account with a net asset value on the date of the notice of redemption less than
the minimum investment as specified by the Trustees. At least 60 days advance
written notice of any such involuntary redemption is required and the
shareholder is given an opportunity to purchase the required value of additional
shares at the next determined net asset value without sales charge. Any
applicable contingent deferred sales charge will be deducted from the proceeds
of this redemption. Any involuntary redemption may only occur if the shareholder
account is less than the minimum investment due to shareholder redemptions.
 
  REINSTATEMENT PRIVILEGE. Holders of Class A Shares or Class B Shares who have
redeemed shares of the respective Fund may reinstate any portion or all of the
net
 
                                       46
<PAGE>   433
 
proceeds of such redemption in Class A Shares of such Fund. Holders of Class C
Shares who have redeemed shares of the respective Fund may reinstate any portion
or all of the net proceeds of such redemption in Class C Shares of such Fund
with credit given for any contingent deferred sales charge paid upon such
redemption. Such reinstatement is made at the net asset value 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." Reinstatement at net asset value is also offered to participants in
those eligible retirement plans held or administered by Van Kampen American
Capital Trust Company for repayment of principal (and interest) on their
borrowings on such plans.
 
- ------------------------------------------------------------------------------
THE DISTRIBUTION AND SERVICE PLANS
- ------------------------------------------------------------------------------
 
  Each of the Funds has adopted a distribution plan (the "Distribution Plan")
with respect to each class of its shares pursuant to Rule 12b-1 under the 1940
Act. Each of the Funds also has adopted a service plan (the "Service Plan") with
respect to each class of shares. The Distribution Plan and Service Plan of each
Fund provide that the respective Fund may spend a portion of such Fund's average
daily net assets attributable to each class of its shares in connection with the
distribution of respective class of shares and in connection with the provision
of ongoing services to shareholders of each class. Each Distribution Plan and
Service Plan is being implemented through an agreement with the Distributor and
sub-agreements between the Distributor and brokers, dealers and financial
intermediaries (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance.
 
  CLASS A SHARES.  Each of the Funds may spend an aggregate amount up to 0.25%
per year of the average daily net assets attributable to the Class A Shares of
the respective Fund pursuant to its Distribution Plan and Service Plan. From
such amount, the respective Fund may spend up to 0.25% per year of the average
daily net assets attributable to its Class A Shares pursuant to its Service Plan
in connection with the ongoing provision of services to holders of such shares
by the Distributor and by brokers, dealers or financial intermediaries and in
connection with the maintenance of such shareholders' accounts. Each of the
Funds pays the Distributor the lesser of the balance of the 0.25% not paid to
such brokers, dealers or financial intermediaries or the amount of the
Distributor's actual distribution related expense.
 
  CLASS B SHARES.  Each of the Funds may spend up to 0.75% per year of the
average daily net assets attributable to the Class B Shares of the respective
Fund pursuant to the Distribution Plan. In addition, each of the Funds may spend
up to 0.25% per year of such Fund's average daily net assets attributable to the
Class B Shares of the respective Fund pursuant to its Service Plan in connection
with the ongoing provision of services to holders of such shares by the
Distributor
 
                                       47
<PAGE>   434
 
and by brokers, dealers or financial intermediaries and in connection with the
maintenance of such shareholders' accounts.
 
  CLASS C SHARES.  Each of the Funds may spend up to 0.75% per year of the
average daily net assets attributable to the Class C Shares of the respective
Fund pursuant to the Distribution Plan. From such amount, each of the Funds, or
the Distributor as agent for the respective Fund, pays brokers, dealers or
financial intermediaries in connection with the distribution of the Class C
Shares up to 0.75% of the respective Fund's average daily net assets
attributable to Class C Shares maintained in such Fund more than one year by
such broker's, dealer's or financial intermediary's customers. Each of the Funds
pays the Distributor the lesser of the balance of 0.75% not paid to such
brokers, dealers or financial intermediaries or the amount of the Distributor's
actual distribution related expense. In addition, each of the Funds may spend up
to 0.25% per year of the average daily net assets attributable to the Class C
Shares of the respective Fund pursuant to its Service Plan in connection with
the ongoing provision of services to holders of such shares by the Distributor
and by brokers, dealers or financial intermediaries and in connection with the
maintenance of such shareholders' accounts.
 
  OTHER INFORMATION.  Amounts payable to the Distributor with respect to the
Class A Shares under the Distribution Plan in a given year may not fully
reimburse the Distributor for its actual distribution related expenses during
such year. In such event, with respect to the Class A Shares, there is no
carryover of such reimbursement obligations to succeeding years.
 
  The Distributor's actual expenses with respect to a class of CDSC Shares (for
purposes of this section, excluding any Class A Shares that may be subject to a
CDSC) for any given year may exceed the amounts payable to the Distributor with
respect to such class of CDSC Shares under the Distribution Plan, the Service
Plan and payments received pursuant to the contingent deferred sales charge. In
such event, with respect to any such class of CDSC Shares, any unreimbursed
expenses will be carried forward and paid by the respective Fund (up to the
amount of the actual expenses incurred) in future years so long as such
Distribution Plan is in effect. Except as mandated by applicable law, the Funds
do not impose any limit with respect to the number of years into the future that
such unreimbursed expenses may be carried forward (on a fund level basis).
Because such expenses are accounted on a fund level basis, in periods of extreme
net asset value fluctuation such amounts with respect to a particular CDSC Share
may be greater or less than the amount of the initial commission (including
carrying cost) paid by the Distributor with respect to such CDSC Share. In such
circumstances, a shareholder of such CDSC Share may be deemed to incur expenses
attributable to other shareholders of such class. Each of the Funds will
disclose in its prospectus from time to time the then current amount of any such
unreimbursed expenses with respect to each class of CDSC Shares expressed as a
dollar amount and as a percent of the respective Fund's total net assets. As of
December 31, 1994, there were $38,971 and $2,788 of unreimbursed distribution
expenses with respect to Class B
 
                                       48
<PAGE>   435
 
Shares and Class C Shares, respectively of the Insured Fund, representing less
than 0.01% and less than 0.01% of the Insured Fund's total net assets. As of
December 31, 1994, there were $20,141 and $4,129 of unreimbursed distribution
expenses with respect to Class B Shares and Class C Shares, respectively of the
California Insured Fund, representing 0.01% and less than 0.01% of the
California Insured Fund's total net assets. If the Distribution Plan was
terminated or not continued, the Funds would not be contractually obligated to
pay the Distributor for any expenses not previously reimbursed by the Fund or
recovered through contingent deferred sales charges.
 
  Because each of the Funds is a series of the Trust, amounts paid to the
Distributor as reimbursement for expenses of one series of the Trust may
indirectly benefit the other funds which are series of the Trust. The
Distributor will endeavor to allocate such expenses among such funds in an
equitable manner. The Distributor will not use the proceeds from the contingent
deferred sales charge applicable to a particular class of CDSC Shares to defray
distribution related expenses attributable to any other class of CDSC Shares.
Various federal and state laws prohibit national banks and some state-chartered
commercial banks from underwriting or dealing in the Funds' shares. In addition,
state securities laws on this issue may differ from the interpretations of
federal law, and banks and financial institutions may be required to register as
dealers pursuant to state law. In the unlikely event that a court were to find
that these laws prevent such banks from providing such services described above,
the Funds would seek alternate providers and expects that shareholders would not
experience any disadvantage.
 
- ------------------------------------------------------------------------------
DISTRIBUTIONS FROM THE FUNDS
- ------------------------------------------------------------------------------
 
  Each Fund's policy is to declare daily and pay monthly distributions of all or
substantially all net investment income of such Fund. Each Fund's net recognized
investment income consists of all of its respective interest income, dividends
and other ordinary income earned by such Fund on its portfolio assets, less all
expenses of such Fund. Expenses of the Funds are accrued each day. Net long- and
short-term capital gains, if any, are expected to be distributed, to the extent
permitted by applicable law, to shareholders at least annually. Distributions
cannot be assured, and the amount of each monthly distribution may vary.
 
  Distributions with respect to each class of shares will be calculated in the
same manner on the same day and will be in the same amount, except that the
different distribution and service fees and any incremental administrative
expenses relating to each class of shares will be borne exclusively by the
respective class and may cause the distributions relating to the different
classes of shares to differ. Generally, distributions with respect to a class of
shares subject to a higher distribution fee, service fee, or, where applicable,
the conversion feature will be lower than distributions with respect to a class
of shares subject to a lower distribution fee, service fee, or not subject to
the conversion feature.

  Investors will be entitled to begin receiving dividends on their shares on the
business day after such Fund's transfer agent receives payments for such shares.
However, shares become entitled to dividends on the day such Fund's transfer
agent receives payment for the shares either through a fed wire or NSCC
settlement. Shares remain entitled to dividends through the day such shares are
processed for payment on redemption.
 
  Distribution checks may be sent to parties other than the shareholder in whose
name the account is registered. Persons wishing to utilize this service should
complete the appropriate section of the account application accompanying this
Prospectus or available from Van Kampen American Capital Funds, c/o ACCESS, P.O.
Box 418256, Kansas City, MO 64141-9256. After ACCESS receives this completed
form, distribution checks will be sent to the bank or other person so designated
by such shareholder.
 
  PURCHASE OF ADDITIONAL SHARES WITH DISTRIBUTIONS.  Each Fund will
automatically credit dividend distributions and any net long-term capital gain
distributions to a shareholder's account in additional shares of the respective
Fund valued at net asset value, without a sales charge. Unless a shareholder
instructs otherwise, the reinvestment plan is automatic. This instruction may be
made by telephone by calling (800) 421-5666 ((800) 772-8889 for the hearing
impaired) or in writing to ACCESS.
 
- ------------------------------------------------------------------------------
TAX STATUS
- ------------------------------------------------------------------------------
 
  FEDERAL TAXES.  The Funds each have qualified and intend to continue to
qualify as regulated investment companies under Subchapter M of the Code. To
qualify as a regulated investment company, each Fund must comply with certain
requirements of the Code relating to, among other things, the source of its
income and diversification of its assets. If each Fund so qualifies and if it
distributes to its shareholders at least 90% of its net investment income
(including tax-exempt interest and other taxable income including net short-term
capital gains, but not net capital gains, which is the excess of net long-term
capital gains over net short-term capital losses), it will not be required to
pay federal income taxes on any income distributed to shareholders. Each Fund
intends to distribute at least the minimum amount of net investment income to
satisfy the 90% distribution requirement. Each Fund will not be subject to
federal income tax on any net capital gain distributed to its shareholders. In
order to avoid a 4% excise tax each Fund will be required to distribute by
December 31 of each year at least 98% of its ordinary income for such year and
at least 98% of its capital gain net income (the latter of which is generally
computed on the basis of the one-year period ending on October 31 of such year),
plus any required distribution amounts that were not distributed in previous
taxable years. For purposes of the excise tax, any ordinary income or capital
gain net income retained by, and taxed in the hands of, a Fund will be treated
as having been distributed.
 
                                       50
<PAGE>   437
 
  If a Fund qualifies as a regulated investment company and satisfies the 90%
distribution requirement, and if, at the close of each quarter of such Fund's
taxable year, at least 50% of the total of such Fund's assets consists of
obligations exempt from federal income tax ("tax-exempt obligations"), such Fund
will be qualified to pay exempt-interest dividends to its shareholders to the
extent of its tax-exempt interest income (less expenses applicable thereto).
Exempt-interest dividends are excludable from a shareholder's gross income for
federal income tax purposes, but may be taxable distributions for state, local
and other tax purposes. Exempt-interest dividends are included, however, in
determining what portion, if any, of a person's social security and railroad
retirement benefits will be includable in gross income subject to federal income
tax. Interest expense with respect to indebtedness incurred or continued by a
shareholder to purchase or carry shares of a Fund is not deductible to the
extent that such interest relates to exempt-interest dividends received from
such Fund.
 
  The Internal Revenue Service has publicly ruled that payments of insurance
proceeds representing interest on defaulted tax-exempt obligations are
excludable from gross income to the same extent that such payments would have
been excludable if they had been directly made by the issuer of the insured
obligations. Accordingly, insurance proceeds received by the Insured Fund and
the California Insured Fund under a policy obtained for such securities prior to
their purchase by such Funds or from AMBAC and any other insurer with whom the
Insured Fund and the California Insured Fund maintains a policy described in
this Prospectus will be tax-exempt interest income of the Insured Fund and the
California Insured Fund to the same extent as if such payments were made by the
issuer of the insured obligations, and will be includable by the Insured Fund
and the California Insured Fund in calculating their exempt-interest dividends.
With respect to municipal leases with "non-appropriation" clauses, however,
there can be no assurance that payments made by the insurers on such lease
obligations will be tax-exempt interest income of the Insured Fund or the
California Insured Fund to the same extent as if such payments were made by the
issuer of the obligations and, therefore, includable by the Funds in calculating
their exempt-interest dividends.
 
  Distributions of a Fund's investment company taxable income (which does not
include tax-exempt interest income) are taxable to shareholders as ordinary
income whether received in shares or in cash. Shareholders who receive
distributions in the form of additional shares will have a basis for federal
income tax purposes in each such share equal to the value thereof on the
reinvestment date. Distributions of a Fund's net capital gain ("capital gains
dividends"), if any, are taxable to shareholders at the rates applicable to
long-term capital gains regardless of the length of time shares of such Fund
have been held by such shareholders. Distributions in excess of the Funds'
earnings and profits, such as distributions of principal, will first reduce the
adjusted tax basis of the shares held by the shareholders and, after such
adjusted tax basis is reduced to zero, will constitute capital gains to such
shareholders (assuming such shares are held as a capital asset). Each Fund will
inform shareholders of the source and tax status of such distributions promptly
after the
 
                                       51
<PAGE>   438
 
close of each calendar year. Distributions from the Funds will not be eligible
for the dividends received deduction for corporations.
 
  Exempt-interest dividends allocable to interest received by a Fund on certain
"private activity" obligations issued after August 7, 1986 will be treated as
interest on such obligations and thus will give rise to an item of tax
preference that will increase a shareholder's alternative minimum taxable
income. Unless otherwise provided in regulations, the portion of the Fund's
interest on such "private activity" obligations allocable to shareholders will
correspond to the portion of the Fund's total net tax-exempt income distributed
to shareholders. In addition, for corporations, alternative minimum taxable
income will be increased by a percentage of the amount by which a measure of
income that includes interest on tax-exempt obligations exceeds the amount
otherwise determined to be the alternative minimum taxable income. Accordingly,
investment in a Fund may cause shareholders to be subject to (or result in an
increased liability under) the alternative minimum tax.
 
  Exempt-interest dividends will not be tax-exempt to the extent made to any
shareholder who is a "substantial user" of the facilities financed by tax-exempt
obligations held by the Fund or "related persons" of such substantial users.
 
  Redemption or resale of shares of a Fund will be a taxable transaction for
federal income tax purposes. Redeeming shareholders will recognize gain or loss
in an amount equal to the difference between their basis in such redeemed shares
of such Fund and the amount received. If such shares are held as a capital
asset, the gain or loss will be a capital gain or loss and will generally be
long-term if such shareholders have held shares for more than one year. Any loss
realized on shares held for six months or less will be disallowed to the extent
of any exempt-interest dividends received with respect to such shares. If such
loss is not entirely disallowed, it will be treated as a long-term capital loss
to the extent of any capital gains dividends received with respect to such
shares.
 
  Some of the Funds' investment practices are subject to special provisions of
the Code that, among other things, may defer the use of certain losses of a Fund
and affect the holding period of the securities held by a Fund and the character
of gains or losses realized by a Fund. These provisions may also require a Fund
to mark-to-market some of the positions in its portfolio (i.e., treat them as if
they were closed out), which may cause such Fund to recognize income without
receiving cash with which to make distributions in amounts necessary to satisfy
the 90% distribution requirement and the distribution requirement for avoiding
income taxes. Each Fund will monitor its transactions and may make certain tax
elections in order to mitigate the effect of these rules and prevent
disqualification of such Fund as a regulated investment company.
 
  Investments of each Fund in securities issued at a discount or providing for
deferred interest or payment of interest in kind are subject to special tax
rules that will affect the amount, timing and character of distributions to
shareholders. For example, with respect to securities issued at a discount, each
Fund will be required
 
                                       52
<PAGE>   439
 
to accrue as income each year a portion of the discount and to distribute such
income each year in order to maintain its qualification as a regulated
investment company and to avoid federal income taxes. In order to generate
sufficient cash to make distributions necessary to satisfy the 90% distribution
requirement and avoid federal income taxes, a Fund may have to dispose of
securities that it would otherwise have continued to hold. Discount relating to
certain stripped tax-exempt obligations may constitute taxable income when
distributed to shareholders.
 
  A Fund's ability to dispose of portfolio securities may be limited by the
requirement for qualification as a regulated investment company that less than
30% of a Fund's gross income be derived from the disposition of securities held
for less than three months.
 
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in such a month and paid in January of the following
year will be treated as having been distributed by the Fund and received by the
shareholders on the December 31 of the year in which the dividend was declared.
In addition, certain other distributions made after the close of a taxable year
of the Fund may be "spilled back" and treated as paid by the Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
shareholders will be treated as having received such dividends in the taxable
year in which the distribution is actually made.
 
  Each Fund is required, in certain circumstances, to withhold 31% of taxable
dividends and certain other payments, including redemptions, paid to
shareholders who do not furnish to the Fund their correct taxpayer
identification number (in the case of individuals, their social security number)
and certain required certifications or who are otherwise subject to backup
withholding.
 
  CALIFORNIA TAX STATUS. Under existing California income tax law, if at the
close of each quarter of the California Insured Fund's taxable year at least 50%
of the value of its total assets consists of obligations of the State of
California and its political subdivisions, shareholders of the California
Insured Fund who are subject to the California personal income tax will not be
subject to such tax on distributions with respect to their shares of the
California Insured Fund to the extent that such distributions are attributable
to such tax-exempt interest from such obligations (less expenses applicable
thereto). If such distributions are received by a corporation subject to the
California franchise tax, however, the distributions will be includable in its
gross income for purposes of determining its California franchise tax.
Corporations subject to the California corporate income tax may be subject to
such taxes with respect to distributions from the California Insured Fund.
Accordingly, an investment in shares of the California Insured Fund may not be
appropriate for corporations subject to either tax. Under California personal
property tax law, securities owned by the California Insured Fund and any
interest thereon are exempt from such personal property tax. Any proceeds paid
to the California Insured Fund under the insurance policy which represents
matured interest on
 
                                       53
<PAGE>   440
 
defaulted obligations should be exempt from California personal income tax if,
and to the same extent as, such interest would have been exempt if paid by the
issuer of such defaulted obligations. Recent amendments to California tax laws
substantially incorporate those provisions of the Code governing the treatment
of regulated investment companies.
 
  GENERAL. The federal and California income tax discussions set forth above are
for general information only. Prospective investors should consult their tax
advisors regarding the specific federal and California tax consequences of
holding and disposing of shares as well as the effects of other state, local and
foreign tax laws.
 
- ------------------------------------------------------------------------------
FUND PERFORMANCE
- ------------------------------------------------------------------------------
 
  From time to time advertisements and other sales materials for each respective
Fund may include information concerning the historical performance of such Fund.
Any such information will include the average total return of such Fund
calculated on a compounded basis for specified periods of time. Such
advertisements and sales material may also include a yield quotation as of a
current period. In each case, such total return and yield information, if any,
will be calculated pursuant to rules established by the SEC and will be computed
separately for each class of a Fund's shares. In lieu of or in addition to total
return and yield calculations, such information may include performance rankings
and similar information from independent organizations such as Lipper Analytical
Services, Inc., Business Week, Forbes or other industry publications.
 
  The yield quotations are determined for each class of a Fund's shares on a
monthly basis with respect to the immediately preceding 30 day period. Yield is
computed by dividing the respective Fund's net investment income per share
earned during such 30 day period by such Fund's maximum offering price per share
on the last day of such period. Net investment income per share for a class of
shares is determined by taking the interest earned by the respective Fund during
the period and allocable to the class of shares, subtracting the expenses (net
of reimbursements) accrued for the period and allocable to the class of shares,
and dividing the result by the product of (a) the average daily number of such
class of shares of the respective Fund outstanding during the period that were
entitled to receive dividends and (b) such Fund's maximum offering price per
share on the last day of the period. The yield calculation formula assumes net
investment income is earned and reinvested at a constant rate and annualized at
the end of a six month period.
 
  Tax-equivalent yield demonstrates the taxable yield required to produce an
after-tax yield equivalent to that of a Fund's yield. A tax-equivalent yield
quotation for a 30 day period as described above is computed for each class of a
Fund's shares by dividing that portion of the yield of such Fund (as computed
above) which is tax-exempt by a percentage equal to 100% minus a stated
percentage income tax rate and adding the result to that portion of such Fund's
yield, if any, that is not tax-exempt.
 
                                       54
<PAGE>   441
 
  The average compounded total return for each class of a Fund's shares is
calculated by determining the redemption value at the end of specified periods
(after adding back all dividends and other distributions made during the period)
of a $1,000 investment in a class of shares of such Fund (less the maximum sales
charge) at the beginning of the period, annualizing the increase or decrease
over the specified period with respect to such initial investment and expressing
the result as a percentage.
 
  Total return figures utilized by each Fund are based on historical performance
and are not intended to indicate future performance. Total return and net asset
value per share can be expected to fluctuate over time, and accordingly upon
redemption a shareholder's shares may be worth more or less than their original
cost.
 
  Each of the Funds may, in supplemental sales literature, advertise
non-standardized total return figures representing the cumulative,
non-annualized total return of such Fund from a given date to a subsequent given
date. Cumulative non-standardized total return is calculated by measuring the
value of an initial investment in such Fund at a given time, including or
excluding any applicable sales charge as indicated, deducting the respective
Fund's maximum sales charge, determining the value of all subsequent reinvested
distributions, and dividing the net change in the value of the investment as of
the end of the period by the amount of the initial investment and expressing the
result as a percentage.
 
  From time to time either Fund may include in its supplemental sales literature
and shareholder reports a quotation of the current "distribution rate" for the
respective Fund. Distribution rate is a measure of the level of income and
short-term capital gain dividends, if any, distributed for a specified period.
Distribution rate is determined by annualizing the distributions per share for a
stated period and dividing the result by the public offering price for the same
period. It differs from yield, which is a measure of the income actually earned
by a Fund's investments, and from total return, which is a measure of the income
actually earned by, plus the effect of any realized and unrealized appreciation
or depreciation of, such investments during a stated period. Distribution rate
is, therefore, not intended to be a complete measure of a Fund's performance.
Distribution rate may sometimes be greater than yield since, for instance, it
may not include the effect of amortization of bond premiums, and may include
non-recurring short-term capital gains and premiums from futures transactions
engaged in by a Fund. Distribution rates will be calculated separately for each
class of a Fund's shares.
 
  From time to time, a Fund may compare its performance to certain securities
and unmanaged indices which may have different risk/reward characteristics than
the Fund. Such characteristics may include, but are not limited to, tax
features, guarantees, insurance and the fluctuation of principal and/or return.
In addition, from time to time, a Fund may utilize sales literature that
includes hypotheticals.

Fund is a separate series of the Trust, a Delaware business trust. The Insured
Fund was originally organized as a Maryland corporation under the name Van
Kampen Merritt Insured Tax Free Fund Inc., was subsequently reorganized into a
sub-trust of Van Kampen Merritt Tax Free Fund, a Massachusetts business trust,
under the name Van Kampen Merritt Insured Tax Free Income Fund as of February
22, 1988 and was again reorganized as a series of the Trust on July 31, 1995.
The California Insured Fund was organized under the name Van Kampen Merritt
California Insured Tax Free Fund as a sub-trust of Van Kampen Merritt Tax Free
Fund and was reorganized as a series of the Trust on July 31, 1995. Shares of
the Trust entitle their holders to one vote per share; however, separate votes
are taken by each series on matters affecting an individual series. The Trust
does not contemplate holding regular meetings of shareholders to elect Trustees
or otherwise. However, the holders of 10% or more of the outstanding shares may
by written request require a meeting to consider the removal of Trustees by a
vote of two-thirds of the shares then outstanding cast in person or by proxy at
such meeting. The Trust will assist such holders in communicating with other
shareholders of the Funds to the extent required by the 1940 Act. More detailed
information concerning the Trust is set forth in the Statement of Additional
Information of each Fund.
 
  Each Fund's fiscal year ends on December 31. Each of the Funds send to their
shareholders, at least semi-annually, reports showing the respective Fund's
portfolio and other information. An annual report, containing financial
statements audited by independent public accountants, is sent to shareholders
each year. After the end of each year, shareholders will receive federal income
tax information regarding dividends and capital gains distributions.

                             THE FUND AND THE TRUST
 
  The Fund is a separate diversified series of the Trust is an unincorporated
business trust established under the laws of the State of Delaware by an
Agreement and Declaration of Trust dated as of May 10, 1995, (the "Declaration
of Trust"). The Declaration of Trust permits the Trustees to create one or more
separate investment portfolios and issue a series of shares for each portfolio.
The Trustees can further sub-divide each series of shares into one or more
classes of shares for each portfolio. At present, the Fund, Van Kampen American
Capital Tax Free High Income Fund, Van Kampen American Capital California
Insured Tax Free Fund, Van Kampen American Capital Municipal Income Fund, Van
Kampen American Capital Limited Term Municipal Income Fund, Van Kampen American
Capital Florida Insured Tax Free Income Fund, Van Kampen American Capital New
Jersey Tax Free Income Fund and Van Kampen American Capital New York Tax Free
Income Fund have been organized as series of the Trust and have commenced
investment operations. Van Kampen American Capital California Tax Free Income
Fund, Van Kampen American Capital Michigan Tax Free Income Fund, Van Kampen
American Capital Missouri Tax Free Income Fund and Van Kampen American Capital
Ohio Tax Free Income Fund have been organized as series of the Trust but have
not commenced investment operations. Other series may be organized and offered
in the future. The Fund was originally organized as a Maryland corporation under
the name Van Kampen Merritt Insured Tax Free Fund Inc., was subsequently
reorganized into a sub-trust of Van Kampen Merritt Tax Free Fund, a
Massachusetts business trust, under the name Van Kampen Merritt Insured Tax Free
Income Fund as of February 22, 1988 and was again reorganized as a series of the
Trust on July 31, 1995.
 
  Each share in a series of the Trust represents an equal proportionate interest
in the assets of such series with each other share in such series and no
interest in any other series. No series is subject to the liabilities of any
other series. The Declaration of Trust provides that shareholders are not liable
for any liabilities of the Trust or any of its series, requires inclusion of a
clause to that effect in every agreement entered into by the Trust or any of its
series and indemnifies shareholders against any such liability.
 
  Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series. For example, a change in investment policy for a series would be voted
upon by shareholders of only the series involved. Shares do not have cumulative
voting rights, preemptive rights or any conversion or exchange rights other than
those described in the Prospectus. The Trust does not contemplate holding
regular meetings of shareholders to elect Trustees or otherwise. However, the
holders of 10% or more of the outstanding shares may by written request require
a meeting to consider the removal of Trustees by a vote of two-thirds of the
shares then outstanding cast in person or by proxy at such meeting.
 
  The Trustees may amend the Declaration of Trust (including with respect to any
series) in any manner without shareholder approval, except that the Trustees may
not adopt any amendment adversely affecting the rights of shareholders of any
series without approval by a majority of the outstanding shares of each affected
series entitled to vote (or such higher vote as may be required by the
Investment Company Act of 1940, as amended (the "1940 Act"), or other applicable
law).
 
  Statements contained in this Statement of Additional Information to the
contents of any contract or other document referred to are not necessarily
complete, and, in each instance, reference is made to the copy of such contract
or other document filed as an exhibit to the Registration Statement of which
this Statement of Additional Information forms a part, each such statement being
qualified in all respects by such reference.
 
                      INVESTMENT POLICIES AND RESTRICTIONS
 
  The investment objective of the Fund is set forth in the Prospectus under the
caption "Investment Objectives and Policies." There can be no assurance that the
Fund will achieve its objective.
 
  Fundamental investment restrictions limiting the investments of the Fund
provide that the Fund may not:
 
  1. Purchase any securities (other than tax exempt obligations guaranteed by
     the United States Government or by its agencies or instrumentalities), if
     as a result more than 5% of the Fund's total assets (taken at current
     value) would then be invested in securities of a single issuer or if as a
     result the Fund would hold more than 10% of the outstanding voting
     securities of any single issuer.
 
                                       B-2
<PAGE>   450
 
   2. Invest more than 25% of its assets in a single industry. (As described in
      the Prospectus, the Fund may from time to time invest more than 25% of its
      assets in a particular segment of the municipal bond market; however, the
      Fund will not invest more than 25% of its assets in industrial development
      bonds in a single industry.)
 
   3. Borrow money, except from banks for temporary purposes and then in amounts
      not in excess of 5% of the total asset value of the Fund, or mortgage,
      pledge or hypothecate any assets except in connection with a borrowing and
      in amounts not in excess of 10% of the total asset value of the Fund.
      Borrowings may not be made for investment leverage, but only to enable the
      Fund to satisfy redemption requests where liquidation of portfolio
      securities is considered disadvantageous or inconvenient. In this
      connection, the Fund will not purchase portfolio securities during any
      period that such borrowings exceed 5% of the total asset value of the
      Fund. Notwithstanding this investment restriction, the Fund may enter into
      "when issued" and "delayed delivery" transactions as described in the
      Prospectus.
 
   4. Make loans, except to the extent the tax exempt obligations the Fund may
      invest in are considered to be loans.
 
   5. Buy any securities "on margin." The deposit of initial or maintained
      margin in connection with interest rate or other financial futures or
      index contracts or related options is not considered the purchase of a
      security on margin.
 
   6. Sell any securities "short," write, purchase or sell puts, calls or
      combinations thereof, or purchase or sell interest rate or other financial
      futures or index contracts or related options, except as hedging
      transactions in accordance with the requirements of the Securities and
      Exchange Commission and the Commodity Futures Trading Commission.
 
   7. Act as an underwriter of securities, except to the extent the Fund may be
      deemed to be an underwriter in connection with the sale of securities held
      in its portfolio.
 
   8. Make investments for the purpose of exercising control or participation in
      management.
 
   9. Invest in securities of other investment companies, except as part of a
      merger, consolidation or other acquisition and except that the Fund may
      invest up to 10% of its assets in tax exempt money market funds that
      invest in securities rated comparably to those the Fund may invest in so
      long as the Fund does not own more than 3% of the outstanding voting stock
      of any tax exempt money market fund or securities of any tax exempt money
      market fund aggregating in value more than 5% of the total assets of the
      Fund.
 
  10. Invest in equity interests in oil, gas or other mineral exploration of
      development programs.
 
  11. Purchase or sell real estate, commodities or commodity contracts, except
      as set forth in item 6 above and except to the extent the municipal
      securities the Fund may invest in are considered to be interests in real
      estate.
 
  The Fund may not change any of these investment restrictions nor any other
fundamental policy as they apply to the Fund without the approval of the lesser
of (i) more than 50% of the Fund's outstanding shares or (ii) 67% of the Fund's
shares present at a meeting at which the holders of more than 50% of the
outstanding shares are present in person or by proxy. As long as the percentage
restrictions described above are satisfied at the time of the investment or
borrowing, the Fund will be considered to have abided by those restrictions even
if, at a later time, a change in values or net assets causes an increase or
decrease in percentage beyond that allowed.
 
  The Fund generally will not engage in the trading of securities for the
purpose of realizing short-term profits, but it will adjust its portfolio as
deemed advisable in view of prevailing or anticipated market conditions to
accomplish the Fund's investment objectives. For example, the Fund may sell
portfolio securities in anticipation of a movement in interest rates. Frequency
of portfolio turnover will not be a limiting factor if the Fund considers it
advantageous to purchase or sell securities. Portfolio turnover is calculated by
dividing the lesser of purchases or sales of portfolio securities by the monthly
average value of the securities in the portfolio during the year. Securities,
including options, whose maturity or expiration date at the time of acquisition
were one year or less are excluded from such calculation. The Fund anticipates
that its annual portfolio turnover rate will normally be less than 100%.
 
                                       B-3
<PAGE>   451
 
  The Fund does not intend to invest in certain "private activity" obligations
issued after August 7, 1986. Interest on such "private activity" obligations is
treated as a preference item for the purpose of calculating the alternative
minimum tax. If the Fund were to invest in such "private activity" obligations,
dividends paid to an investor who is subject to the alternative minimum tax
might not be completely tax exempt or might cause an investor to be subject to
such tax.
 
                      ADDITIONAL INVESTMENT CONSIDERATIONS
 
  MUNICIPAL SECURITIES.  Municipal securities include long-term obligations,
which are often called municipal bonds, as well as shorter term municipal notes,
municipal leases, and tax-exempt commercial paper. Under normal market
conditions, longer term municipal securities generally provide a higher yield
than shorter term municipal securities, and therefore the Fund generally expects
to be invested primarily in longer term municipal securities. The Fund will,
however, invest in shorter term municipal securities when yields are greater
than yields available on longer term municipal securities, for temporary
defensive purposes and when redemption requests are expected. The two principal
classifications of municipal bonds are "general obligation" and "revenue" or
"special obligation" bonds, which include "industrial revenue bonds." General
obligation bonds are secured by the issuer's pledge of its faith, credit, and
taxing power for the payment of principal and interest. Revenue or special
obligation bonds are payable only from the revenues derived from a particular
facility or class of facilities or, in some cases, from the proceeds of a
special tax or other specific revenue source such as from the user of the
facility being financed.
 
  Also included within the general category of municipal securities are
participations in lease obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of municipal authorities
or entities used to finance the acquisition of equipment and facilities.
Although lease obligations do not constitute general obligations of the
municipality for which the municipality's taxing power is pledged, a lease
obligation is ordinarily backed by the municipality's covenant to budget for,
appropriate and make the payments due under the lease obligation. However,
certain lease obligations contain "non-appropriation" clauses which provide that
the municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a
yearly basis. In addition to the "non-appropriation" risk, these securities
represent a relatively new type of financing that has not yet developed the
depth of marketability associated with more conventional bonds. Although
"non-appropriation" lease obligations are often secured by the underlying
property, disposition of the property in the event of foreclosure might prove
difficult. There is no limitation on the percentage of the Fund's assets that
may be invested in "non-appropriation" lease obligations. In evaluating such
lease obligations, the Adviser will consider such factors as it deems
appropriate, which factors may include (a) whether the lease can be cancelled,
(b) the ability of the lease obligee to direct the sale of the underlying
assets, (c) the general creditworthiness of the lease obligor, (d) the
likelihood that the municipality will discontinue appropriating funding for the
leased property in the event such property is no longer considered essential by
the municipality, (e) the legal recourse of the lease obligee in the event of
such a failure to appropriate funding and (f) any limitations which are imposed
on the lease obligor's ability to utilize substitute property or services than
those covered by the lease obligation.
 
  Also included within the term Municipal Securities are participation
certificates issued by state and local governments or authorities to finance the
acquisition of equipment and facilities. They may represent participations in a
lease, an installment purchase contract, or a conditional sales contract. Some
municipal leases and participation certificates may not be readily marketable.
 
  The "issuer" of municipal securities generally is deemed to be the
governmental agency, authority, instrumentality or other political subdivision,
or the non-governmental user of a revenue bond-financed facility, the assets and
revenues of which will be used to meet the payment obligations, or the guarantee
of such payment obligations, of the municipal securities.
 
  The Fund may purchase floating and variable rate demand notes, which are
municipal securities normally having a stated maturity in excess of one year,
but which permit the holder to demand payment of principal at any time, or at
specified intervals. The issuer of such notes normally has a corresponding
right, after a given period, to prepay at its discretion upon notice to the
noteholders the outstanding principal amount of the notes
 
                                       B-4

plus accrued interest. The interest rate on a floating rate demand note is based
on a known lending rate, such as a bank's prime rate, and is adjusted
automatically each time such rate is adjusted. The interest rate on a variable
rate demand note is adjusted automatically at specified intervals.
 
  The Fund also may invest up to 15% of its total assets in derivative variable
rate municipal securities such as inverse floaters whose rates vary inversely
with changes in market rates of interest. Such derivative variable rate
municipal securities may pay a rate of interest determined by applying a
multiple to the variable rate. The extent of increases and decreases in the
value of derivative municipal securities whose rates vary inversely with changes
in market rates of interest in response to such changes in market rates
generally will be larger than comparable changes in the value of an equal
principal amount of a fixed rate municipal security having similar credit
quality, redemption provisions and maturity. In addition, the Fund may invest in
derivative municipal securities the terms of which include elements of, or are
similar in effect to, certain Strategic Transactions in which the Fund may
engage. Such municipal securities may by their terms, for example, have economic
characteristics comparable to, among other things, a swap, cap, floor or collar
transaction with respect to such security for a period of time prior to its
stated maturity. See "Additional Investment Considerations -- Strategic
Transactions" in this Statement of Additional Information.
 
  The Fund may also acquire custodial receipts or certificates underwritten by
securities dealers or banks that evidence ownership of future interest payments,
principal payments or both on certain municipal securities. The underwriter of
these certificates or receipts typically purchases municipal securities and
deposits the securities in an irrevocable trust or custodial account with a
custodian bank, which then issues receipts or certificates that evidence
ownership of the periodic unmatured coupon payments and the final principal
payment on the obligations. Although under the terms of a custodial receipt, the
Fund typically would be authorized to assert its rights directly against the
issuer of the underlying obligation, the Fund could be required to assert
through the custodian bank those rights as may exist against the underlying
issuer. Thus, in the event the underlying issuer fails to pay principal and/or
interest when due, the Fund may be subject to delays, expenses and risks that
are greater than those that would have been involved if the Fund had purchased a
direct obligation of the issuer. In addition, in the event that the trust or
custodial account in which the underlying security has been deposited is
determined to be an association taxable as a corporation, instead of a
non-taxable entity, the yield on the underlying security would be reduced in
recognition of any taxes paid.
 
  Although the municipal securities in which the Fund may invest will be insured
as to timely payment of both principal and interest, municipal securities, like
other debt obligations, are subject to the risk of non-payment. The ability of
issuers of municipal securities to make timely payments of interest and
principal may be adversely impacted in general economic downturns and as
relative governmental cost burdens are allocated and reallocated among federal,
state and local governmental units. Such non-payment would result in a reduction
of income to the Fund, and could result in a reduction in the value of the
municipal security experiencing non-payment and a potential decrease in the net
asset value of the Fund. Issuers of municipal securities might seek protection
under the bankruptcy laws. In the event of bankruptcy of such an issuer, the
Fund could experience delays and limitations with respect to the collection of
principal and interest on such municipal securities and the Fund may not, in all
circumstances, be able to collect all principal and interest to which it is
entitled. To enforce its rights in the event of a default in the payment of
interest or repayment of principal, or both, the Fund may take possession of and
manage the assets securing the issuer's obligations on such securities, which
may increase the Fund's operating expenses and adversely affect the net asset
value of the Fund. Any income derived from the Fund's ownership or operation of
such assets may not be tax-exempt. In addition, the Fund's intention to qualify
as a "regulated investment company" under the Internal Revenue Code of 1986, as
amended (the "Code"), may limit the extent to which the Fund may exercise its
rights by taking possession of such assets, because as a regulated investment
company the Fund is subject to certain limitations on its investments and on the
nature of its income.
 
  INVESTMENT PRACTICES.  If the Adviser deems it appropriate to seek to hedge
the Fund's portfolio against market value changes, the Fund may buy or sell
derivative instruments such as financial futures contracts and related options,
such as municipal bond index futures contracts and the related put or call
options contracts on such index futures. A tax exempt bond index fluctuates with
changes in the market values of the tax exempt bonds included in the index. An
index future is an agreement pursuant to which two parties agree to receive or
deliver at settlement an amount of cash equal to a specified dollar amount
multiplied by the difference
 
                                       B-5
<PAGE>   453
 
between the value of the index at the close of the last trading day of the
contract and the price at which the future was originally written. A financial
future is an agreement between two parties to buy and sell a security for a set
price on a future date. An index future has similar characteristics to a
financial future except that settlement is made through delivery of cash rather
than the underlying securities. An example is the Long-Term Municipal Bond
futures contract traded on the Chicago Board of Trade. It is based on the Bond
Buyer's Municipal Bond Index, which represents an adjusted average price of the
forty most recent long-term municipal issues of $50 million or more ($75 million
in the instance of housing issues) rated A or better by either Moody's Investors
Service, Inc. ("Moody's") or Standard & Poor's Ratings Group ("S&P"), maturing
in no less than nineteen years, having a first call in no less than seven nor
more than sixteen years, and callable at par.
 
  The Fund may engage in "when issued" and "delayed delivery" transactions and
utilize futures contracts and options thereon for hedging purposes. The
Securities and Exchange Commission ("SEC") generally requires that when mutual
funds, such as the Fund, effect transactions of the foregoing nature, such funds
must either segregate cash or readily marketable portfolio securities with its
custodian in an amount of its obligations under the foregoing transactions, or
cover such obligations by maintaining positions in portfolio securities, futures
contracts or options that would serve to satisfy or offset the risk of such
obligations. When effecting transactions of the foregoing nature, the Fund will
comply with such segregation or cover requirements.
 
STRATEGIC TRANSACTIONS.
 
  The Fund may, but is not required to, utilize various other investment
strategies as described below to hedge various market risks (such as interest
rates and broad or specific market movements) or to manage the effective
maturity or duration of the Fund's fixed-income securities. Such strategies are
generally accepted by modern portfolio managers and are regularly utilized by
many mutual funds and other institutional investors. Techniques and instruments
may change over time as new instruments and strategies are developed or
regulatory changes occur.
 
  In the course of pursuing these investment strategies, the Fund may purchase
and sell derivative instruments such as exchange-listed and over-the-counter put
and call options on securities, fixed-income indices and other financial
instruments, purchase and sell financial futures contracts and options thereon,
enter into various interest rate transactions such as swaps, caps, floors or
collars (collectively, all the above are called "Strategic Transactions").
Strategic Transactions may be used to attempt to protect against possible
changes in the market value of securities held in or to be purchased for the
Fund's portfolio resulting from securities markets fluctuations, to protect the
Fund's unrealized gains in the value of its portfolio securities, to facilitate
the sale of such securities for investment purposes, to manage the effective
maturity or duration of the Fund's portfolio, or to establish a position in the
derivatives markets as a temporary substitute for purchasing or selling
particular securities.
 
  Any or all of these investment techniques may be used at any time and there is
no particular strategy that dictates the use of one technique rather than
another, as use of any Strategic Transaction is a function of numerous variables
including market conditions. The ability of the Fund to utilize these Strategic
Transactions successfully will depend on the Adviser's ability to predict
pertinent market movements, which cannot be assured. The Fund will comply with
applicable regulatory requirements when implementing these strategies,
techniques and instruments. Strategic Transactions involving financial futures
and options thereon will be purchased, sold or entered into only for bona fide
hedging, risk management or portfolio management purposes and not for
speculative purposes.
 
  Strategic Transactions have risks associated with them including possible
default by the other party to the transaction, illiquidity and, to the extent
the Adviser's view as to certain market movements is incorrect, the risk that
the use of such Strategic Transactions could result in losses greater than if
they had not been used. Use of put and call options may result in losses to the
Fund, force the sale or purchase of portfolio securities at inopportune times or
for prices other than current market values, limit the amount of appreciation
the Fund can realize on its investments or cause the Fund to hold a security it
might otherwise sell. The use of options and futures transactions entails
certain other risks. In particular, the variable degree of correlation between
 
                                       B-6
<PAGE>   454
 
price movements of futures contracts and price movements in the related
portfolio position of the Fund creates the possibility that losses on the
hedging instrument may be greater than gains in the value of the Fund's
position. In addition, futures and options markets may not be liquid in all
circumstances and certain over-the-counter options may have no markets. As a
result, in certain markets, the Fund might not be able to close out a
transaction without incurring substantial losses, if at all. Although the use of
futures and options transactions for hedging should tend to minimize the risk of
loss due to a decline in the value of the hedged position, at the same time they
tend to limit any potential gain which might result from an increase in value of
such position. Finally, the daily variation margin requirements for futures
contracts would create a greater ongoing potential financial risk than would
purchases of options, where the exposure is limited to the cost of the initial
premium. Losses resulting from the use of Strategic Transactions would reduce
net asset value, and possibly income, and such losses can be greater than if the
Strategic Transactions had not been utilized. Income earned or deemed to be
earned, if any, by the Fund from its Strategic Transactions will generally be
taxable income of the Fund. See "Tax Status" in the Prospectus.
 
  GENERAL CHARACTERISTICS OF OPTIONS.   Put options and call options typically
have similar structural characteristics and operational mechanics regardless of
the underlying instrument on which they are purchased or sold. Thus, the
following general discussion relates to each of the particular types of options
discussed in greater detail below. In addition, many Strategic Transactions
involving options require segregation of Fund assets in special accounts, as
described below under "Use of Segregated and Other Special Accounts."
 
  A put option gives the purchaser of the option, upon payment of a premium, the
right to sell, and the writer the obligation to buy, the underlying security,
commodity, index, or other instrument at the exercise price. For instance, the
Fund's purchase of a put option on a security might be designed to protect its
holdings in the underlying instrument (or, in some cases, a similar instrument)
against a substantial decline in the market value by giving the Fund the right
to sell such instrument at the option exercise price. A call option, upon
payment of a premium, gives the purchaser of the option the right to buy, and
the seller the obligation to sell, the underlying instrument at the exercise
price. The Fund's purchase of a call option on a security, financial future,
index, or other instrument might be intended to protect the Fund against an
increase in the price of the underlying instrument that it intends to purchase
in the future by fixing the price at which it may purchase such instrument. An
American style put or call option may be exercised at any time during the option
period while a European style put or call option may be exercised only upon
expiration or during a fixed period prior thereto. The Fund is authorized to
purchase and sell exchange listed options and over-the-counter options ("OTC
options"). Exchange listed options are issued by a regulated intermediary such
as the Options Clearing Corporation ("OCC"), which guarantees the performance of
the obligations of the parties to such options. The discussion below uses the
OCC as a paradigm, but is also applicable to other financial intermediaries.
 
  With certain exceptions, OCC issued and exchange listed options generally
settle by physical delivery of the underlying security or currency, although in
the future cash settlement may become available. Index options and Eurodollar
instruments are cash settled for the net amount, if any, by which the option is
"in-the-money" (i.e., where the value of the underlying instrument exceeds, in
the case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed options are closed by entering into
offsetting purchase or sale transactions that do not result in ownership of the
new option.
 
  The Fund's ability to close out its position as a purchaser or seller of an
OCC or exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. Among the possible reasons for the absence of a
liquid option market on an exchange are: (i) insufficient trading interest in
certain options; (ii) restrictions on transactions imposed by an exchange; (iii)
trading halts, suspensions or other restrictions imposed with respect to
particular classes or series of options or underlying securities including
reaching daily price limits; (iv) interruption of the normal operations of the
OCC or an exchange; (v) inadequacy of the facilities of an exchange or OCC to
handle current trading volume; or (vi) a decision by one or more exchanges to
discontinue the trading of options (or a particular class or series of options),
in which event the
 
                                       B-7
<PAGE>   455
 
relevant market for that option on that exchange would cease to exist, although
outstanding options on that exchange would generally continue to be exercisable
in accordance with their terms.
 
  The hours of trading for listed options may not coincide with the hours during
which the underlying financial instruments are traded. To the extent that the
option markets close before the markets for the underlying financial
instruments, significant price and rate movements can take place in the
underlying markets that cannot be reflected in the option markets.
 
  OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC option, including such terms as method of settlement, term, exercise price,
premium, guarantees and security, are set by negotiation of the parties. The
Fund will only sell OTC options that are subject to a buy-back provision
permitting the Fund to require the Counterparty to sell the option back to the
Fund at a formula price within seven days. The Fund expects generally to enter
into OTC options that have cash settlement provisions, although it is not
required to do so.
 
  Unless the parties provide for it, there is no central clearing or guaranty
function in an OTC option. As a result, if the Counterparty fails to make or
take delivery of the security, or other instrument underlying an OTC option it
has entered into with the Fund or fails to make a cash settlement payment due in
accordance with the terms of that option, the Fund will lose any premium it paid
for the option as well as any anticipated benefit of the transaction.
Accordingly, the Adviser must assess the creditworthiness of each such
Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be satisfied.
The Fund will engage in OTC option transactions only with United States
government securities dealers recognized by the Federal Reserve Bank of New York
as "primary dealers", or broker dealers, domestic or foreign banks or other
financial institutions which have received (or the guarantors of the obligation
of which have received) a short-term credit rating of "A-1" from S&P or "P-1"
from Moody's or an equivalent rating from any other nationally recognized
statistical rating organization ("NRSRO"). The staff of the SEC currently takes
the position that, in general, OTC options on securities other than U.S.
Government securities purchased by the Fund, and portfolio securities "covering"
the amount of the Fund's obligation pursuant to an OTC option sold by it (the
cost of the sell-back plus the in-the-money amount, if any) are illiquid, and
are subject to the Fund's limitation on investing no more than 15% of its assets
in illiquid securities.
 
  If the Fund sells a call option, the premium that it receives may serve as a
partial hedge, to the extent of the option premium, against a decrease in the
value of the underlying securities or instruments in its portfolio or will
increase the Fund's income. The sale of put options can also provide income.
 
  The Fund may purchase and sell call options on securities, including U.S.
Treasury and agency securities, municipal obligations, mortgage-backed
securities and Eurodollar instruments that are traded on U.S. and foreign
securities exchanges and in the over-the-counter markets. All calls sold by the
Fund must be "covered" (i.e., the Fund must own the securities or futures
contract subject to the call) or must meet the asset segregation requirements
described below as long as the call is outstanding. Even though the Fund will
receive the option premium to help protect it against loss, a call sold by the
Fund exposes the Fund during the term of the option to possible loss of
opportunity to realize appreciation in the market price of the underlying
security or instrument and may require the Fund to hold a security or instrument
which it might otherwise have sold.
 
  The Fund may purchase and sell put options on securities including U.S.
Treasury and agency securities, mortgage-backed securities, municipal
obligations and Eurodollar instruments (whether or not it holds the above
securities in its portfolio.) The Fund will not sell put options if, as a
result, more than 50% of the Fund's assets would be required to be segregated to
cover its potential obligations under such put options other than those with
respect to futures and options thereon. In selling put options, there is a risk
that the Fund may be required to buy the underlying security at a
disadvantageous price above the market price.
 
  GENERAL CHARACTERISTICS OF FUTURES.  The Fund may enter into financial futures
contracts or purchase or sell put and call options on such futures as a hedge
against anticipated interest rate or fixed-income market
 
                                       B-8
<PAGE>   456
 
changes, for duration management and for risk management purposes. Futures are
generally bought and sold on the commodities exchanges where they are listed
with payment of initial and variation margin as described below. The purchase of
a futures contract creates a firm obligation by the Fund, as purchaser, to take
delivery from the seller the specific type of financial instrument called for in
the contract at a specific future time for a specified price (or, with respect
to index futures and Eurodollar instruments, the net cash amount). The sale of a
futures contract creates a firm obligation by the Fund, as seller, to deliver to
the buyer the specific type of financial instrument called for in the contract
at a specific future time for a specified price (or, with respect to index
futures and Eurodollar instruments, the net cash amount). Options on futures
contracts are similar to options on securities except that an option on a
futures contract gives the purchaser the right in return for the premium paid to
assume a position in a futures contract and obligates the seller to deliver such
option.
 
  The Fund's use of financial futures and options thereon will in all cases be
consistent with applicable regulatory requirements and in particular the rules
and regulations of the Commodity Futures Trading Commission and will be entered
into only for bona fide hedging, risk management (including duration management)
or other portfolio management purposes. Typically, maintaining a futures
contract or selling an option thereon requires the Fund to deposit with a
financial intermediary as security for its obligations an amount of cash or
other specified assets (initial margin) which initially is typically 1% to 10%
of the face amount of the contract (but may be higher in some circumstances).
Additional cash or assets (variation margin) may be required to be deposited
thereafter on a daily basis as the mark to market value of the contract
fluctuates. The purchase of options on financial futures involves payment of a
premium for the option without any further obligation on the part of the Fund.
If the Fund exercises an option on a futures contract it will be obligated to
post initial margin (and potential subsequent variation margin) for the
resulting futures position just as it would for any position. Futures contracts
and options thereon are generally settled by entering into an offsetting
transaction but there can be no assurance that the position can be offset prior
to settlement at an advantageous price nor that delivery will occur.
 
  The Fund will not enter into a futures contract or related option (except for
closing transactions) if, immediately thereafter, the sum of the amount of its
initial margin and premiums on open futures contracts and options thereon would
exceed 5% of the Fund's total assets (taken at current value); however, in the
case of an option that is in-the-money at the time of the purchase, the
in-the-money amount may be excluded in calculating the 5% limitation. The
segregation requirements with respect to futures contracts and options thereon
are described below.
 
  OPTIONS ON SECURITIES INDICES AND OTHER FINANCIAL INDICES.  The Fund also may
purchase and sell call and put options on securities indices and other financial
indices and in so doing can achieve many of the same objectives it would achieve
through the sale or purchase of options on individual securities or other
instruments. Options on securities indices and other financial indices are
similar to options on a security or other instrument except that, rather than
settling by physical delivery of the underlying instrument, they settle by cash
settlement, i.e., an option on an index gives the holder the right to receive,
upon exercise of the option, an amount of cash if the closing level of the index
upon which the option is based exceeds, in the case of a call, or is less than,
in the case of a put, the exercise price of the option (except if, in the case
of an OTC option, physical delivery is specified). This amount of cash is equal
to the excess of the closing price of the index over the exercise price of the
option, which also may be multiplied by a formula value. The seller of the
option is obligated, in return for the premium received, to make delivery of
this amount. The gain or loss on an option on an index depends on price
movements in the instruments making up the market, market segment, industry or
other composite on which the underlying index is based, rather than price
movements in individual securities, as is the case with respect to options on
securities.
 
  COMBINED TRANSACTIONS.  The Fund may enter into multiple transactions,
including multiple options transactions, multiple futures transactions and
multiple interest rate transactions and any combination of futures, options and
interest rate transactions ("component" transactions), instead of a single
Strategic Transaction, as part of a single or combined strategy when, in the
opinion of the Adviser, it is in the best interests of the Fund to do so. A
combined transaction will usually contain elements of risk that are present in
each of its component transactions. Although combined transactions are normally
entered into based on the Adviser's judgment that the combined strategies will
reduce risk or otherwise more effectively achieve the
 
                                       B-9
<PAGE>   457
 
desired portfolio management goal, it is possible that the combination will
instead increase such risks or hinder achievement of the portfolio management
objective.
 
  SWAPS, CAPS, FLOORS AND COLLARS.  Among the Strategic Transactions into which
the Fund may enter are interest rate and index swaps and the purchase or sale of
related caps, floors and collars. The Fund expects to enter into these
transactions primarily to preserve a return or spread on a particular investment
or portion of its portfolio, as a duration management technique or to protect
against any increase in the price of securities the Fund anticipates purchasing
at a later date. The Fund intends to use these transactions as hedges and not as
speculative investments and will not sell interest rate caps or floors where it
does not own securities or other instruments providing the income stream the
Fund may be obligated to pay. Interest rate swaps involve the exchange by the
Fund with another party of their respective commitments to pay or receive
interest, e.g., an exchange of floating rate payments for fixed rate payments
with respect to a notional amount of principal. An index swap is an agreement to
swap cash flows on a notional amount based on changes in the values of the
reference indices. The purchase of a cap entitles the purchaser to receive
payments on a notional principal amount from the party selling such cap to the
extent that a specified index exceeds a predetermined interest rate or amount.
The purchase of a floor entitles the purchaser to receive payments on a notional
principal amount from the party selling such floor to the extent that a
specified index falls below a predetermined interest rate or amount. A collar is
a combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates or values.
 
  The Fund will usually enter into swaps on a net basis, i.e., the two payment
streams are netted out in a cash settlement on the payment date or dates
specified in the instrument, with the Fund receiving or paying, as the case may
be, only the net amount of the two payments. Inasmuch as these swaps, caps,
floors and collars are entered into for good faith hedging purposes, the Adviser
and the Fund believe such obligations do not constitute senior securities under
the 1940 Act and, accordingly, will not treat them as being subject to its
borrowing restrictions. The Fund will not enter into any swap, cap, floor or
collar transaction unless, at the time of entering into such transaction, the
unsecured long-term debt of the Counterparty, combined with any credit
enhancements, is rated at least "A" by S&P or Moody's or has an equivalent
equity rating from an NRSRO or is determined to be of equivalent credit quality
by the Adviser. If there is a default by the Counterparty, the Fund may have
contractual remedies pursuant to the agreements related to the transaction. The
swap market has grown substantially in recent years with a large number of banks
and investment banking firms acting both as principals and agents utilizing
standardized swap documentation. As a result, the swap market has become
relatively liquid. Caps, floors and collars are more recent innovations for
which standardized documentation has not yet been fully developed and,
accordingly, they are less liquid than swaps.
 
  USE OF SEGREGATED AND OTHER SPECIAL ACCOUNTS.  Many Strategic Transactions, in
addition to other requirements, require that the Fund segregate liquid
high-grade assets with its custodian to the extent Fund obligations are not
otherwise "covered" through ownership of the underlying security, financial
instrument or currency. In general, either the full amount of any obligation by
the Fund to pay or deliver securities or assets must be covered at all times by
the securities, instruments or currency required to be delivered, or, subject to
any regulatory restrictions, an amount of cash or liquid high-grade securities
at least equal to the current amount of the obligation must be segregated with
the custodian. The segregated assets cannot be sold or transferred unless
equivalent assets are substituted in their place or it is no longer necessary to
segregate them. For example, a call option written by the Fund will require the
Fund to hold the securities subject to the call (or securities convertible into
the needed securities without additional consideration) or to segregate liquid
high-grade securities sufficient to purchase and deliver the securities if the
call is exercised. A call option sold by the Fund on an index will require the
Fund to own portfolio securities which correlate with the index or to segregate
liquid high-grade assets equal to the excess of the index value over the
exercise price on a current basis. A put option written by the Fund requires the
Fund to segregate liquid, high-grade assets equal to the exercise price.
 
  OTC options entered into by the Fund, including those on securities, financial
instruments or indices and OCC issued and exchange listed index options, will
generally provide for cash settlement. As a result, when the Fund sells these
instruments it will only segregate an amount of assets equal to its accrued net
obligations, as there is no requirement for payment or delivery of amounts in
excess of the net amount. These amounts will
 
                                      B-10
<PAGE>   458
 
equal 100% of the exercise price in the case of a non cash-settled put, the same
as an OCC guaranteed listed option sold by the Fund, or the in-the-money amount
plus any sell-back formula amount in the case of a cash-settled put or call. In
addition, when the Fund sells a call option on an index at a time when the
in-the-money amount exceeds the exercise price, the Fund will segregate, until
the option expires or is closed out, cash or cash equivalents equal in value to
such excess. OCC issued and exchange listed options sold by the Fund other than
those above generally settle with physical delivery, and the Fund will segregate
an amount of assets equal to the full value of the option. OTC options settling
with physical delivery, or with an election of either physical delivery or cash
settlement, will be treated the same as other options settling with physical
delivery.
 
  In the case of a futures contract or an option thereon, the Fund must deposit
initial margin and possible daily variation margin in addition to segregating
assets sufficient to meet its obligation to purchase or provide securities or
currencies, or to pay the amount owed at the expiration of an index- based
futures contract. Such assets may consist of cash, cash equivalents, liquid debt
or equity securities or other acceptable assets.
 
  With respect to swaps, the Fund will accrue the net amount of the excess, if
any, of its obligations over its entitlements with respect to each swap on a
daily basis and will segregate an amount of cash or liquid high-grade securities
having a value equal to the accrued excess. Caps, floors and collars require
segregation of assets with a value equal to the Fund's net obligation, if any.
 
  Strategic Transactions may be covered by other means when consistent with
applicable regulatory policies. The Fund may also enter into offsetting
transactions so that its combined position, coupled with any segregated assets,
equals its net outstanding obligation in related options and Strategic
Transactions. For example, the Fund could purchase a put option if the strike
price of that option is the same or higher than the strike price of a put option
sold by the Fund. Moreover, instead of segregating assets if the Fund held a
futures or forward contract, it could purchase a put option on the same futures
or forward contract with a strike price as high or higher than the price of the
contract held. Other Strategic Transactions may also be offset in combinations.
If the offsetting transaction terminates at the time of or after the primary
transaction no segregation is required, but if it terminates prior to such time,
assets equal to any remaining obligation would need to be segregated.
 
  The Fund's activities involving Strategic Transactions may be limited by the
requirements of Subchapter M of the Code for qualification as a regulated
investment company. See "Tax Status" in the Prospectus.
 
  Illiquid Securities.  The Fund may invest up to 15% of its total assets in
illiquid securities, securities the disposition of which is subject to
substantial legal or contractual restrictions on resale and securities that are
not readily marketable. The sale of restricted and illiquid securities often
requires more time and results in higher brokerage charges or dealer discounts
and other selling expenses than does the sale of securities eligible for trading
on national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale. Restricted securities salable among qualified
institutional buyers without restriction pursuant to Rule 144A under the
Securities Act of 1933 that are determined to be liquid by the Adviser under
guidelines adopted by the Board of Trustees of the Trust (under which guidelines
the Adviser will consider factors such as trading activities and the
availability of price quotations), will not be treated as restricted securities
by the Fund pursuant to such rules. The Fund may, from time to time, adopt a
more restrictive limitation with respect to investment in illiquid and
restricted securities in order to comply with the most restrictive state
securities law, currently 10%. This policy does not include restricted
securities eligible for resale pursuant to Rule 144A under the Securities Act of
1933, as amended, which the Board of Trustees or the Fund's investment adviser
has determined under Board-approved guidelines to be liquid.
 
  INSURANCE.  As described in the Prospectus, the Fund will generally invest
only in municipal securities which are either pre-insured under a policy
obtained for such securities prior to the purchase of such securities or will be
insured under policies obtained by the Fund to cover otherwise uninsured
securities.
 
  Original Issue Insurance.  Original Issue Insurance is purchased with respect
to a particular issue of municipal securities by the issuer thereof or a third
party in conjunction with the original issuance of such municipal securities.
Under such insurance, the insurer unconditionally guarantees to the holder of
the insured municipal security the timely payment of principal and interest on
such obligation when and as such payments
 
                                      B-11
<PAGE>   459
 
shall become due but shall not be paid by the issuer, except that in the event
of any acceleration of the due date of the principal by reason of mandatory or
optional redemption (other than acceleration by reason of a mandatory sinking
fund payment), default or otherwise, the payments insured may be made in such
amounts and at such times as payments of principal would have been due had there
not been such acceleration. The insurer is responsible for such payments less
any amounts received by the holder from any trustee for the municipal security
issuers or from any other source. Original Issue Insurance generally does not
insure payment on an accelerated basis, the payment of any redemption premium
(except with respect to certain premium payments in the case of certain small
issue industrial development and pollution control municipal securities), the
value of the Shares of the Fund or the market value of municipal securities, or
payments of any under purchase price upon the tender of the municipal
securities. Original Issue Insurance does not insure against nonpayment of
principal of or interest on municipal securities resulting from the insolvency,
negligence or any other act or omission of the trustee or other paying agent for
such obligations.
 
  In the event that interest on or principal of a municipal security covered by
insurance is due for payment but is unpaid by reason of nonpayment by the issuer
thereof, the applicable insurer will make payments to its fiscal agent (the
"Fiscal Agent") equal to such unpaid amounts of principal and interest not later
than one business day after the insurer has been notified that such nonpayment
has occurred (but not earlier than the date such payment is due). The Fiscal
Agent will disburse to the Fund the amount of principal and interest which is
then due for payment but is unpaid upon receipt by the Fiscal Agent of (i)
evidence of the Fund's right to receive payment of such principal and interest
and (ii) evidence, including any appropriate instruments of assignment, that all
of the rights of payment of such principal or interest then due for payment
shall thereupon vest in the insurer. Upon payment by the insurer of any
principal or interest payments with respect to any municipal securities, the
insurer shall succeed to the rights of the Fund with respect to such payment.
 
  Original Issue Insurance remains in effect as long as the municipal securities
covered thereby remain outstanding and the insurer remains in business,
regardless of whether the Fund ultimately disposes of such municipal securities.
Consequently, Original Issue Insurance may be considered to represent an element
of market value with respect to the municipal securities so insured, but the
exact effect, if any, of this insurance on such market value cannot be
estimated.
 
  Secondary Market Insurance.  Subsequent to the time of original issuance of a
municipal security, the Fund or a third party may, upon the payment of a single
premium, purchase insurance on such municipal security. Secondary Market
Insurance generally provides the same type of coverage as is provided by
Original Issue Insurance and, as is the case with Original Issue Insurance,
Secondary Market Insurance remains in effect as long as the municipal securities
covered thereby remain outstanding and the insurer remains in business,
regardless of whether the Fund ultimately disposes of such municipal securities.
All premiums respecting municipal securities covered by Original Issue Insurance
or Secondary Market Insurance are paid in advance by the issuer or other party
obtaining the insurance.
 
  One of the purposes of acquiring Secondary Market Insurance with respect to a
particular municipal security would be to enable the Fund to enhance the value
of such municipal security. The Fund, for example, might seek to purchase a
particular municipal security and obtain Secondary Market Insurance with respect
thereto if, in the opinion of the Adviser, the market value of such municipal
security, as insured, would exceed the current value of the municipal security
without insurance plus the cost of the Secondary Market Insurance. Similarly, if
the Fund owns but wishes to sell a municipal security that is then covered by
Portfolio Insurance, the Fund might seek to obtain Secondary Market Insurance
with respect thereto if, in the opinion of the Adviser, the net proceeds of a
sale by the Fund of such obligation, as insured, would exceed the current value
of such obligation plus the cost of the Secondary Market Insurance.
 
  Portfolio Insurance.  The portfolio insurance policies obtained by the Fund
would insure the payment of principal and interest on specified eligible
municipal securities purchased by the Fund. Except as described below, Portfolio
Insurance generally provides the same type of coverage as is provided by
Original Issue Insurance or Secondary Market Insurance. Municipal securities
insured under one Portfolio Insurance policy generally would not be insured
under any other policy purchased by the Fund. A municipal security is eligible
for coverage under a policy if it meets certain requirements of the insurer.
Portfolio Insurance is intended to reduce financial risk, but the cost thereof,
and compliance with investment restrictions imposed under the
 
                                      B-12
<PAGE>   460
 
policy will reduce the yield to shareholders of the Fund. If a municipal
security already is covered by Original Issue Insurance or Secondary Market
Insurance, the Fund is not required to additionally insure any such municipal
security under any policy of Portfolio Insurance that the Fund may purchase.
 
  Portfolio Insurance policies are effective only as to municipal securities
owned and held by the Fund, and do not cover municipal securities for which the
contract for purchase fails. A "when-issued" municipal security will be covered
under a Portfolio Insurance policy upon the settlement date of the issue of such
"when-issued" municipal security.
 
  In determining whether to insure municipal securities held by the Fund, an
insurer will apply its own standards, which correspond generally to the
standards it has established for determining the insurability of new issues of
municipal securities. See "Original Issue Insurance" above.
 
  Each Portfolio Insurance policy will be non-cancellable and will remain in
effect so long as the Fund is in existence, the municipal securities covered by
the policy continue to be held by the Fund, and the Fund pays the premiums for
the policy. Each insurer generally will reserve the right at any time upon 90
days written notice to the Fund to refuse to insure any additional securities
purchased by the Fund after the effective date of such notice. The Board of
Trustees of the Fund generally will reserve the right to terminate each policy
upon seven days written notice to an insurer if it determines that the cost of
such policy is not reasonable in relation to the value of the insurance to the
Fund.
 
  Each Portfolio Insurance policy shall terminate as to any municipal security
that has been redeemed from or sold by the Fund on the date of such redemption
or the settlement date of such sale, and an insurer shall not have any liability
thereafter under a policy as to any such municipal security, except that if the
date of such redemption or the settlement date of such sale occurs after a
record date and before the related payment date with respect to any such
municipal security, the policy will terminate as to such municipal security on
the business day immediately following such payment date. Each policy will
terminate as to all municipal securities covered thereby on the date on which
the last of the covered municipal securities mature, are redeemed or are sold by
the Fund.
 
  One or more policies of Portfolio Insurance may provide the Fund, pursuant to
an irrevocable commitment of the insurer, with the option to exercise the right
to obtain permanent insurance ("Permanent Insurance") with respect to a
municipal security that is to be sold by the Fund. The Fund would exercise the
right to obtain Permanent Insurance upon payment of a single, predetermined
insurance premium payable from the proceeds of the sale of such municipal
security. It is expected that the Fund will exercise the right to obtain
Permanent Insurance for a municipal security only if, in the opinion of the
Adviser, upon such exercise the net proceeds from the sale by the Fund of such
obligation, as insured, would exceed the proceeds from the sale of such
obligation without insurance. The Permanent Insurance premium with respect to
each such obligation is determined based upon the insurability of each such
obligation of the date of purchase by the Fund and will not be increased or
decreased for any change in the creditworthiness of such obligation unless such
obligation is in default as to payment of principal or interest, or both. In
such event, the Permanent Insurance premium shall be subject to an increase
predetermined at the date of purchase by the Fund.
 
  Because such Portfolio Insurance policy will terminate as to municipal
securities sold by the Fund on the date of sale, in which event the insurer will
be liable only for those payments of principal and interest that are then due
and owing (unless Permanent Insurance is obtained by the Fund), the provision
for this insurance will not enhance the marketability of securities held by the
Fund, whether or not the securities are in default or in significant risk of
default. On the other hand, since Original Issue Insurance and Secondary Market
Insurance will remain in effect as long as municipal securities covered thereby
are outstanding, such insurance may enhance the marketability of such securities
even when such securities are in default or in significant risk of default, but
the exact effect, if any, on the marketability cannot be estimated. Accordingly,
the Fund may determine to retain or, alternatively, to sell municipal securities
by Original Issue Insurance or Secondary Market Insurance that are in default or
in significant risk of default.
 
  It is anticipated that certain of the municipal securities to be purchased by
the Fund will be insured under policies obtained by persons other than the Fund.
In instances in which the Fund purchases municipal securities insured under
policies obtained by persons other than the Fund, the Fund does not pay the
 
                                      B-13
<PAGE>   461
 
premiums for such policies; rather the cost of such policies may be reflected in
a higher purchase price for such municipal securities. Accordingly, the yield on
such municipal securities may be lower than that on similar uninsured municipal
securities. Premiums for a Portfolio Insurance Policy generally are paid by the
Fund monthly, and are adjusted for purchases and sales of municipal securities
covered by the policy during the month. The yield on the Fund's portfolio is
reduced to the extent of the insurance premiums paid by the Fund which, in turn,
will depend upon the characteristics of the covered municipal securities held by
the Fund. In the event the Fund were to purchase Secondary Market Insurance with
respect to any municipal securities then covered by a Portfolio Insurance
policy, the coverage and the obligation of the Fund to pay monthly premiums
under such policy would cease with such purchase.
 
  There can be no assurance that insurance of the kind described above will
continue to be available to the Fund. In the event that such insurance is no
longer available or that the cost of such insurance outweighs the benefits to
the Fund in the view of the Board of Trustees, the Board will consider whether
to modify the investment policies of the Fund, which may require the approval of
shareholders. In the event the claims-paying ability rating of an insurer of
municipal securities in the Fund's portfolio were to be lowered from AAA by S&P,
or if the Adviser anticipates such a lowering or otherwise does not believe an
insurer's claims-paying ability merits its existing triple-A rating, the Fund
could seek to obtain additional insurance from an insurer whose claims-paying
ability is rated AAA by S&P or, if the Adviser determines that the cost of
obtaining such additional insurance outweigh the benefits, the Fund may elect
not to obtain additional insurance. In making such determination, the Adviser
will consider the cost of the additional insurance, the new claims-paying
ability rating and financial condition of the existing insurer and the
creditworthiness of the issuer and/or guarantor of the underlying municipal
securities. The Adviser also may determine not to purchase additional insurance
in such circumstances if it believes that the insurer is taking steps which will
cause its triple-A claims-paying ability rating to be restored promptly.
 
  Although the Adviser periodically reviews the financial condition of each
insurer, there can be no assurance that the insurers will be able to honor their
obligations under all circumstances. In that regard, it should be noted that the
claims-paying abilities and debt ratings of several large insurers (at least one
of which insured municipal securities) recently have been lowered by one or more
of the nationally recognized securities rating agencies and that many insurers
currently are experiencing adverse results in their investment portfolios. In
addition, certain insurers' operations recently have been assumed by their state
regulatory agencies. The Fund cannot predict the consequences of a state
takeover of an insurer's obligations and, in particular, whether such an insurer
(or its state regulatory agency) could or would honor all of the insurer's
contractual obligations including any outstanding insurance contracts insuring
the timely payment of principal and interest on municipal securities. The Fund
cannot predict the impact which such events might have on the market values of
such municipal security. In the event of a default by an insurer on its
obligations with respect to any municipal securities in the Fund's portfolio,
the Fund would look to the issuer and/or guarantor of the relevant municipal
securities for payments of principal and interest and such issuer and/or
guarantor may not be rated AAA by S&P. Accordingly, the Fund could be exposed to
greater risk of non-payment in such circumstances which could adversely affect
the Fund's net asset value and the market price per Share. Alternatively, the
Fund could elect to dispose of such municipal securities; however, the market
prices for such municipal securities may be lower than the Fund's purchase price
for them and the Fund could sustain a capital loss as a result.
 
  Although the insurance on municipal securities reduces financial or credit
risk in respect of the insured obligations (i.e., the possibility that owners of
the insured municipal securities will not receive timely scheduled payments of
principal or interest), insured municipal securities remain subject to market
risk (i.e., fluctuations in market value as a result of changes in prevailing
interest rates). Accordingly, insurance on municipal securities does not insure
the market value of the Fund's assets or the net asset value or the market price
for the Shares.
 
  AMBAC Indemnity Corporation.  AMBAC Indemnity is a Wisconsin-domiciled stock
insurance corporation regulated by the Insurance Department of the State of
Wisconsin and licensed to do business in 50 states and the District of Columbia.
On December 31, 1991, AMBAC Indemnity had admitted assets of approximately
$1,431,000,000, total liabilities of approximately $684,400,000 and statutory
capital of approximately $830,000,000. Statutory capital consists of AMBAC
Indemnity's policyholders' surplus and statutory
 
                                      B-14

contingency reserve. AMBAC Indemnity was formerly a wholly-owned subsidiary of
Citicorp Financial Guaranty Holdings, Inc. ("Holdings") (formerly known as AMBAC
Inc.), a financial holding company and itself a wholly-owned subsidiary of
Citibank, N.A. ("Citibank"). According to Best Insurance Report (1991 edition),
AMBAC Indemnity's aggregate exposure under all Class I (municipal bond
insurance) financial guaranty bonds, the only class set forth therein, in force
as of December 31, 1990 was $86,200,000,000.
 
  On May 1, 1991, AMBAC Inc. ("AMBAC Inc."), a financial holding company formed
by Holdings, registered for sale with the Securities and Exchange Commission
17,600,000 shares of its common stock. The registration statement with respect
to such sale was declared effective on July 11, 1991. As a result of the sale,
Citibank, through its affiliate Holdings, owns approximately 49% of the total
equity of AMBAC Inc., with a right to cast 20% of the total number of votes of
all shares of outstanding common stock of AMBAC Inc. until such time as
Citibank, including its affiliates, reduces its equity ownership to less than
25% of AMBAC Inc. (at which time the shares owned by it become non-voting). As
of the date of the consummation of the sale of common stock, AMBAC Indemnity
became a direct wholly owned subsidiary of AMBAC Inc. The Wisconsin Insurance
Department has stated that the sale of common stock described herein does not
require its prior approval. Both Moody's and S&P have reaffirmed that the sale
of the common stock of AMBAC Inc. does not affect AMBAC Indemnity's triple-A
claims-paying ability ratings.
 
  AMBAC Indemnity has entered into pro rata reinsurance agreements under which a
percentage of the insurance underwritten pursuant to certain municipal bond
insurance programs of AMBAC Indemnity has been and will be assumed by a number
of foreign and domestic unaffiliated reinsurers.
 
  Copies of AMBAC Indemnity's financial statements prepared in accordance with
statutory accounting standards are available from AMBAC Indemnity. The address
of AMBAC Indemnity's administrative offices and its telephone number are One
State Street Plaza, 17th Floor, New York, New York 10004 and (212) 668-0340.
 
                  DESCRIPTION OF MUNICIPAL SECURITIES RATINGS
 
  STANDARD & POOR'S RATINGS GROUP--A brief description of the applicable
Standard & Poor's Ratings Group (S&P) rating symbols and their meanings (as
published by S&P) follows:
 
     1.  DEBT
 
          A Standard & Poor's corporate or municipal debt rating is a current
     assessment of the creditworthiness of an obligor with respect to a specific
     obligation. This assessment may take into consideration obligors such as
     guarantors, insurers, or lessees.
 
          The debt rating is not a recommendation to purchase, sell or hold a
     security, inasmuch as it does not comment as to market price or suitability
     for a particular investor.
 
          The ratings are based on current information furnished by the issuer
     or obtained by S&P from other sources it considers reliable. S&P does not
     perform an audit in connection with any rating and may, on occasion, rely
     on unaudited financial information. The ratings may be changed, suspended
     or withdrawn as a result of changes in, or unavailability of, such
     information, or based on other circumstances.
 
        The ratings are based, in varying degrees, on the following
considerations:
 
        1. Likelihood of default--capacity and willingness of the obligor as to
          the timely payment of interest and repayment of principal in
          accordance with the terms of the obligation;
 
        2. Nature of and provisions of the obligation;
 
        3. Protection afforded by, and relative position of, the obligation in
          the event of bankruptcy, reorganization or other arrangement under the
          laws of bankruptcy and other laws affecting creditors' rights.
 
<TABLE>
    <S>       <C>
    AAA       Debt rated 'AAA' has the highest rating assigned by S&P. Capacity to pay
              interest and repay principal is extremely strong.
</TABLE>
 
                                      B-15
<PAGE>   463
 
<TABLE>
    <S>       <C>
    AA        Debt rated 'AA' has a very strong capacity to pay interest and repay principal
              and differs from the higher rated issues only in small degree.
 
    A         Debt rated 'A' has a strong capacity to pay interest and repay principal
              although it is somewhat more susceptible to the adverse effects of changes in
              circumstances and economic conditions than debt in higher rated categories.
 
    BBB       Debt rated 'BBB' is regarded as having an adequate capacity to pay interest and
              repay principal. Whereas it normally exhibits adequate protection parameters,
              adverse economic conditions or changing circumstances are more likely to lead
              to a weakened capacity to pay interest and repay principal for debt in this
              category than in higher rated categories.
 
    BB        Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded, on balance, as
    B         predominantly speculative with respect to capacity to pay interest and repay
    CCC       principal. 'BB' indicates the least degree of speculation and 'C' the highest.
    CC        While such debt will likely have some quality and protective characteristics,
    C         these are outweighed by large uncertainties or large exposures to adverse
              conditions.
 
    BB        Debt rated 'BB' has less near-term vulnerability to default than other
              speculative issues. However, it faces major ongoing uncertainties or exposure
              to adverse business, financial, or economic conditions which could lead to
              inadequate capacity to meet timely interest and principal payments. The 'BB'
              rating category is also used for debt subordinated to senior debt that is
              assigned an actual or implied 'BBB-' rating.
 
    B         Debt rated 'B' has a greater vulnerability to default but currently has the
              capacity to meet interest payments and principal repayments. Adverse business,
              financial, or economic conditions will likely impair capacity or willingness to
              pay interest and repay principal. The 'B' rating category is also used for debt
              subordinated to senior debt that is assigned an actual or implied 'BB' or 'BB-'
              rating.
 
    CCC       Debt rated 'CCC' has a currently identifiable vulnerability to default, and is
              dependent upon favorable business, financial, and economic conditions to meet
              timely payment of interest and repayment of principal. In the event of adverse
              business, financial, or economic conditions, it is not likely to have the
              capacity to pay interest and repay principal. The 'CCC' rating category is also
              used for debt subordinated to senior debt that is assigned an actual or implied
              'B' or 'B-' rating.
 
    CC        The rating 'CC' typically is applied to debt subordinated to senior debt that
              is assigned an actual or implied 'CCC' rating.
 
    C         The rating 'C' typically is applied to debt subordinated to senior debt which
              is assigned an actual or implied 'CCC-' debt rating. The 'C' rating may be used
              to cover a situation where a bankruptcy petition has been filed, but debt
              service payments are continued.
 
    CI        The rating 'CI' is reserved for income bonds on which no interest is being
              paid.
 
    D         Debt rated 'D' is in payment default. The 'D' rating category is used when
              interest payments or principal payments are not made on the date due even if
              the applicable grace period has not expired, unless S&P believes that such
              payments will be made during such grace period. The 'D' rating also will be
              used upon the filing of a bankruptcy petition if debt service payments are
              jeopardized.
</TABLE>
 
           PLUS (+) or MINUS (-): The ratings from 'AA' to 'CCC' may be modified
           by the addition of a plus or minus sign to show relative standing
           within the major categories.
 
<TABLE>
    <S>       <C>
    C         The letter "c" indicates that the holder's option to tender the security for
              purchase may be canceled under certain prestated conditions enumerated in the
              tender option documents.
</TABLE>

<PAGE>   464
 
<TABLE>
    <S>       <C>
    I         The letter "i" indicates the rating is implied. Such ratings are assigned only
              on request to entities that do not have specific debt issues to be rated. In
              addition, implied ratings are assigned to governments that have not requested
              explicit ratings for specific debt issues. Implied ratings on governments
              represent the sovereign ceiling or upper limit for ratings on specific debt
              issues of entities domiciled in the country.
 
    L         The letter "L" indicates that the rating pertains to the principal amount of
              those bonds to the extent that the underlying deposit collateral is federally
              insured and interest is adequately collateralized. In the case of certificates
              of deposit, the letter "L" indicates that the deposit, combined with other
              deposits being held in the same right and capacity, will be honored for
              principal and accrued pre-default interest up to the federal insurance limits
              within 30 days after closing of the insured institution or, in the event that
              the deposit is assumed by a successor insured institution, upon maturity.
 
    P         The letter "p" indicates that the rating is provisional. A provisional rating
              assumes the successful completion of the project being financed by the debt
              being rated and indicates that payment of debt service requirements is largely
              or entirely dependent upon the successful and timely completion of the project.
              This rating, however, while addressing credit quality subsequent to completion
              of the project, makes no comment on the likelihood of, or the risk of default
              upon failure of, such completion. The investor should exercise his own
              judgement with respect to such likelihood and risk.
 
              * Continuance of the rating is contingent upon S&P's receipt of an executed
                copy of the escrow agreement or closing documentation confirming investments
                and cash flows.
 
    NR        Indicates that no public rating has been requested, that there is insufficient
              information on which to base a rating, or that S&P does not rate a particular
              type of obligation as a matter of policy.
</TABLE>
 
          DEBT OBLIGATIONS OF ISSUERS OUTSIDE THE UNITED STATES AND ITS
     TERRITORIES are rated on the same basis as domestic corporate and municipal
     issues. The ratings measure the creditworthiness of the obligor but do not
     take into account currency exchange and related uncertainties.
 
          BOND INVESTMENT QUALITY STANDARDS--Under present commercial bank
     regulations issued by the Comptroller of the Currency, bonds rated in the
     top four categories ("AAA", "AA", "A", "BBB", commonly known as "investment
     grade" ratings) are generally regarded as eligible for bank investment. In
     addition, the laws of various states governing legal investments impose
     certain rating or other standards for obligations eligible for investment
     by savings banks, trust companies, insurance companies, and fiduciaries
     generally.
 
     2.  MUNICIPAL NOTES
 
          A S&P note rating reflects the liquidity concerns and market access
     risks unique to notes. Notes maturing in 3 years or less will likely
     receive a note rating. Notes maturing beyond 3 years will most likely
     receive a long-term debt rating. The following criteria will be used in
     making that assessment.
 
          -- Amortization schedule (the larger the final maturity relative to
             other maturities, the more likely the issue is to be treated as a
             note).
 
          -- Source of payment (the more the issue depends on the market for its
             refinancing, the more likely it is to be treated as a note).
 
        Note rating symbols are as follows:
 
<TABLE>
    <S>       <C>
    SP-1      Strong capacity to pay principal and interest. Issues determined to possess
              very strong characteristics are a plus (+) designation.
 
    SP-2      Satisfactory capacity to pay principal and interest, with some vulnerability to
              adverse financial and economic changes over the term of the notes.

     3.  COMMERCIAL PAPER
 
          A S&P commercial paper rating is a current assessment of the
     likelihood of timely payment of debt having an original maturity of no more
     than 365 days. Ratings are graded into several categories, ranging from
     'A-1' for the highest-quality obligations to 'D' for the lowest. These
     categories are as follows:
 
<TABLE>
    <S>       <C>
    A-1       This highest category indicates that the degree of safety regarding timely
              payment is strong. Those issues determined to possess extremely strong safety
              characteristics are denoted with a plus (+) sign designation.
 
    A-2       Capacity for timely payment on issues with this designation is satisfactory.
              However, the relative degree of safety is not as high as for issues designated
              'A-1'.
 
    A-3       Issues carrying this designation have adequate capacity for timely payment.
              They are, however, more vulnerable to the adverse effects of changes in
              circumstances than obligations carrying the higher designations.
 
    B         Issues rated 'B' are regarded as having only speculative capacity for timely
              payment.
 
    C         This rating is assigned to short-term debt obligations with a doubtful capacity
              for payment.
 
    D         Debt rated 'D' is in payment default. The 'D' rating category is used when
              interest payments or principal payments are not made on the date due, even if
              the applicable grace period has not expired, unless S&P believes that such
              payments will be made during such grace period.
 
    A commercial paper rating is not a recommendation to purchase, sell a security. The
      ratings are based on current information furnished to S&P by the issuer or obtained by
    S&P from other sources it considers reliable. The ratings may be changed, suspended, or
    withdrawn as a result of changes in or unavailability of, such information.
</TABLE>
 
     4.  TAX-EXEMPT DUAL RATINGS
 
          S&P assigns "dual" ratings to all debt issues that have a put option
     or demand feature as part of their structure. The first rating addresses
     the likelihood of repayment of principal and interest as due, and the
     second rating addresses only the demand feature. The long-term debt rating
     symbols are used for bonds to denote the long-term maturity and the
     commercial paper rating symbols for the put option (for example,
     'AAA/A-1+'). With short-term demand debt, S&P's note rating symbols are
     used with the commercial paper symbols (for example, 'SP-1+/A-1+').
 
  MOODY'S INVESTORS SERVICE--A brief description of the applicable Moody's
Investors Service ("Moody's") rating symbols and their meanings (as published by
Moody's) follows:
 
     1.  LONG-TERM MUNICIPAL BONDS
 
<TABLE>
    <S>       <C>
    AAA       Bonds which are rated Aaa are judged to be of the best quality. They carry the
              smallest degree of investment risk and are generally referred to as "gilt
              edged." Interest payments are protected by a large or by an exceptionally
              stable margin and principal is secure. While the various protective elements
              are likely to change, such changes as can be visualized are most unlikely to
              impair the fundamentally strong position of such issues.
 
    AA        Bonds which are rated Aa are judged to be of high quality by all standards.
              Together with the Aaa group they comprise what are generally known as high
              grade bonds. They are rated lower than the best bonds because margins of
              protection may not be as large as in Aaa securities or fluctuation of
              protective elements may be of greater amplitude or there may be other elements
              present which make the long-term risk appear somewhat larger than the Aaa
              securities.
</TABLE>
 
                                      B-18
<PAGE>   466
 
<TABLE>
    <S>       <C>
    A         Bonds which are rated A possess many favorable investment attributes and are to
              be considered as upper-medium-grade obligations. Factors giving security to
              principal and interest are considered adequate, but elements may be present
              which suggest a susceptibility to impairment some time in the future.
 
    BAA       Bonds which are rated Baa are considered as medium-grade obligations, (i.e.,
              they are neither highly protected nor poorly secured). Interest payments and
              principal security appear adequate for the present but certain protective
              elements may be lacking or may be characteristically unreliable over any great
              length of time. Such bonds lack outstanding investment characteristics and in
              fact have speculative characteristics as well.
 
    BA        Bonds which are rated Ba are judged to have speculative elements; their future
              cannot be considered as well-assured. Often the protection of interest and
              principal payments may be very moderate, and thereby not well safeguarded
              during both good and bad times over the future. Uncertainty of position
              characterizes bonds in this class.
 
    B         Bonds which are rated B generally lack characteristics of the desirable
              investment. Assurance of interest and principal payments or of maintenance of
              other terms of the contract over any long period of time may be small.
 
    CAA       Bonds which are rated Caa are of poor standing. Such issues may be in default
              or there may be present elements of danger with respect to principal or
              interest.
 
    CA        Bonds which are rated Ca represent obligations which are speculative in a high
              degree. Such issues are often in default or have other marked shortcomings.
 
    C         Bonds which are rated C are the lowest rated class of bonds, and issues so
              rated can be regarded as having extremely poor prospects of ever attaining any
              real investment standing.
 
    CON (..)  Bonds for which the security depends upon the completion of some act or the
              fulfillment of some condition are rated conditionally and designated with the
              prefix "Con" followed by the rating in parentheses. These are bonds secured by:
              (a) earnings of projects under construction, (b) earnings of projects
              unseasoned in operation experience, (c) rentals which begin when facilities are
              completed, or (d) payments to which some other limiting condition attaches the
              parenthetical rating denotes probable credit stature upon completion of
              construction or elimination of basis of condition.
 
    NOTE:     Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
              classification from AA to B. The modifier 1 indicates that the company ranks in
              the higher end of its generic rating category; the modifier 2 indicates a
              mid-range ranking; and the modifier 3 indicates that the company ranks in the
              lower end of its generic rating category.
</TABLE>
 
     2.  SHORT-TERM EXEMPT NOTES
 
          Moody's ratings for state and municipal short-term obligations will be
     designated Moody's Investment Grade or (MIG). Such ratings recognize the
     differences between short-term credit risk and long-term risk. Factors
     affecting the liquidity of the borrower and short-term cyclical elements
     are critical in short-term ratings, while other factors of major importance
     in bond risk, long-term secular trends for example, may be less important
     over the short run. A short-term rating may also be assigned on an issue
     having a demand feature-variable rate demand obligation. Such ratings will
     be designated as VMIG, SG or, if the demand feature is not rated, as NR.
 
          Moody's short-term ratings are designated Moody's Investment Grade as
     MIG 1 or VMIG 1 through MIG 4 or VMIG 4. As the name implies, when Moody's
     assigns a MIG or VMIG rating, all categories define an investment grade
     situation.
 
          MIG 1/VMIG 1. This designation denotes best quality. There is present
     strong protection by established cash flows, superior liquidity support or
     demonstrated broad-based access to the market for refinancing.
 
                                      B-19
<PAGE>   467
 
          MIG 2/VMIG 2. This designation denotes high quality. Margins of
     protection are ample although not so large as in the preceding group.
 
          MIG 3/VMIG 3. This designation denotes favorable quality. All security
     elements are accounted for but there is lacking the undeniable strength of
     the preceding grades. Liquidity and cash flow protection may be narrow and
     market access for refinancing is likely to be less well established.
 
          MIG 4/VMIG 4. This designation denotes adequate quality. Protection
     commonly regarded as required of an investment security is present and
     although not distinctly or predominantly speculative, there is specific
     risk.
 
          SG. This designation denotes speculative quality. Debt instruments in
     this category lack margins of protection.
 
     3.  TAX-EXEMPT COMMERCIAL PAPER
 
          Moody's short-term debt ratings are opinions of the ability of issuers
     to repay punctually senior debt obligations which have an original maturity
     not exceeding one year. Obligations relying upon support mechanisms such as
     letters-of-credit and bond of Indemnity are excluded unless explicitly
     rated.
 
          Moody's employs the following three designations, all judged to be
     investment grade, to indicate the relative repayment ability of rated
     issuers:
 
             Issuers rated Prime-1 (or supporting institutions) have a superior
        ability for repayment of senior short-term debt obligations.
 
             Issuers rated Prime-2 (or supporting institutions) have a strong
        ability for repayment of senior short-term debt obligations.
 
             Issuers rated Prime-3 (or supporting institutions) have an
        acceptable ability for repayment of senior short-term debt obligations.
 
          Issuers rated Not Prime do not fall within any of the Prime rating
     categories.

  The investment advisory agreement between the Adviser and the Fund provides

services, and permits its officers and employees to serve without compensation
as trustees of the Trust and officers of the Fund if duly elected to such
positions.
 
  The agreement provides that the Adviser shall not be liable for any error of
judgment or of law, or for any loss suffered by the Fund in connection with the
matters to which the agreement relates, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Adviser in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under the agreement.
 
  The Adviser's activities are subject to the review and supervision of the
Board of Trustees of the Trust, of which the Fund is a series, to whom the
Adviser renders periodic reports of the Fund's investment activities.
 
  The advisory agreement will continue in effect from year to year if
specifically approved by the Trustees of the Trust, of which the Fund is a
separate series, (or by the Fund's shareholders) and by the disinterested
Trustees in compliance with the requirements of the 1940 Act. The agreement may
be terminated without penalty upon 60 days written notice by either party and
will automatically terminate in the event of assignment.
 
  The investment advisory agreement specifies that the Adviser will reimburse
each of the Funds for annual expenses of such Funds which exceed the most
stringent limit prescribed by any State in which the Fund's shares are offered
for sale. Currently, the most stringent limit in any State would require such
reimbursement to the extent that aggregate operating expenses of the Fund
(excluding interest, taxes and other expenses which may be excludable under
applicable state law) exceed in any fiscal year 2 1/2% of the average annual net
assets of the Fund up to $30 million, 2% of the average annual net assets of the
Fund of the next $70 million and 1 1/2% of the remaining average annual net
assets of the Fund. In addition to making any required reimbursements, the
Adviser may in its discretion, but is not obligated to, waive all or any portion
of its fee or assume all or any portion of the expenses of any of the Funds.
 
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
advisory expenses of $5,028,401, $4,796,312 and $3,877,766, respectively.
 
  OTHER AGREEMENTS.
 
  ACCOUNTING SERVICES AGREEMENT. The Fund has entered into an accounting
services agreement pursuant to which the VK Adviser provides accounting services
supplementary to those provided by the Custodian. Such
 
                                      B-26
<PAGE>   474
 
services are expected to enable the Fund to more closely monitor and maintain
its accounts and records. The Fund shares with the other Van Kampen American
Capital funds advised by the VK Adviser and distributed by the Distributor in
the cost of providing such services, with 25% of such costs shared
proportionately based on the number of outstanding classes of securities per
Fund and with the remaining 75 percent of such cost being paid by the Fund and
such other Van Kampen American Capital funds based proportionally on their
respective net assets.
 
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $31,650, $19,250 and $18,300, respectively,
representing the VK Adviser's cost of providing accounting services.
 
  LEGAL SERVICES AGREEMENT. The Fund and each of the other Van Kampen American
Capital funds advised by the VK Adviser and distributed by the Distributor have
entered into Legal Services Agreements pursuant to which Van Kampen American
Capital provides legal services, including without limitation: accurate
maintenance of the funds' minute books and records, preparation and oversight of
the funds' regulatory reports, and other information provided to shareholders,
as well as responding to day-to-day legal issues on behalf of the funds. Payment
by the Fund for such services is made on a cost basis for the salary and salary
related benefits, including but not limited to bonuses, group insurances and
other regular wages for the employment of personnel, as well as overhead and the
expenses related to the office space and the equipment necessary to render the
legal services. Other funds distributed by the Distributor also receive legal
services from Van Kampen American Capital. Of the total costs for legal services
provided to funds distributed by the Distributor, one half of such costs are
allocated equally to each fund and the remaining one half of such costs are
allocated to specific funds based on monthly time records.
 
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $25,100, $22,700 and $11,300, respectively,
representing Van Kampen American Capital's cost of providing legal services.
 
  SUPPORT SERVICES AGREEMENT. Under a support services agreement with the
Distributor which terminated as of July 10, 1995 concurrent with the Fund's
change in transfer agent, the Fund received support services for shareholders,
including the handling of all written and telephonic communications, except
initial order entry and other distribution related communications. Payment by
the Fund for such services is made on cost basis for the employment of the
personnel and the equipment necessary to render the support services. At such
time, the Fund, and the other Van Kampen American Capital funds distributed by
the Distributor, shared such costs proportionately among themselves based upon
their respective net asset values.
 
  For the years ended December 31, 1994, 1993 and 1992, the Fund recognized
expenses of approximately $597,765, $423,425 and $359,270, respectively,
representing the Distributor's cost of providing certain support services.
 
                       CUSTODIAN AND INDEPENDENT AUDITORS
 
  State Street Bank and Trust Company, 225 Franklin Street, P.O. Box 1713,
Boston, MA 02105-1713, is the custodian of the Fund and has custody of all
securities and cash of the Fund. The custodian, among other things, attends to
the collection of principal and income, and payment for and collection of
proceeds of securities bought and sold by the Fund.
 
  The independent auditors for the Fund are KPMG Peat Marwick LLP, Chicago,
Illinois. The selection of independent auditors will be subject to ratification
by the shareholders of the Fund at any annual meeting of shareholders.
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATIONS
 
  The Adviser will place orders for portfolio transactions for the Fund with
broker-dealer firms giving consideration to the quality, quantity and nature of
each firms' professional services. These services include execution, clearance
procedures, wire service quotations and statistical and other research
information provided to the Fund and the investment adviser, including
quotations necessary to determine the value of the
 
                                      B-27
<PAGE>   475
 
Fund's net assets. Any research benefits derived are available for all clients
of the investment adviser. Since statistical and other research information is
only supplementary to the research efforts of the Adviser and still must be
analyzed and reviewed by its staff, the receipt of research information is not
expected to materially reduce its expenses.
 
  If it is believed to be in the best interests of the Fund, the Adviser may
place portfolio transactions with brokers who provide the types of research
service described above, even if it means the Fund will have to pay a higher
commission (or, if the broker's profit is part of the cost of the security, will
have to pay a higher price for the security) than would be the case if no weight
were given to the broker's furnishing of those research services. This will be
done, however, only if, in the opinion of the Adviser, the amount of additional
commission or increased cost is reasonable in relation to the value of such
services.
 
  In selecting among the firms believed to meet the criteria for handling a
particular transaction, the Adviser may take into consideration that certain
firms (i) provide market, statistical or other research information such as that
set forth above to the Fund and the Adviser, (ii) have sold or are selling
shares of the Fund and (iii) may select firms that are affiliated with the Fund,
its investment adviser or its distributor and other principal underwriters.
 
  If purchases or sales of securities of the Fund and of one or more other
investment companies or clients advised by the Adviser are considered at or
about the same time, transactions in such securities will be allocated among the
several investment companies and clients in a manner deemed equitable to all by
the Adviser, taking into account the respective sizes of the funds and the
amount of securities to be purchased or sold. Although it is possible that in
some cases this procedure could have a detrimental effect on the price or volume
of the security as far as the Fund is concerned, it is also possible that the
ability to participate in volume transactions and to negotiate lower brokerage
commissions will be beneficial to the Fund.
 
  While the Adviser will be primarily responsible for the placement of the
Fund's business, the policies and practices in this regard must be consistent
with the foregoing and will at all times be subject to review by the Trustees of
the Trust, of which the Fund is a separate series.
 
  The Trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the Securities and Exchange Commission under the 1940 Act which
requires that the commission paid to the Distributor and other affiliates of the
Fund must be reasonable and fair compared to the commissions, fees or other
remuneration received or to be received by other brokers in connection with
comparable transactions involving similar securities during a comparable period
of time. The rule and procedures also contain review requirements and require
the Adviser to furnish reports to the Trustees and to maintain records in
connection with such reviews. After consideration of all factors deemed
relevant, the Trustees will consider from time to time whether the advisory fee
will be reduced by all or a portion of the brokerage commission given to brokers
that are affiliated with the Fund.
 
                             TAX STATUS OF THE FUND
 
  The Trust and each of its series, including the Fund, will be treated as
separate corporations for income tax purposes. The Fund may be subject to tax if
it fails to distribute net capital gains, or if its annual distributions, as a
percentage of its income, are less than the distributions required by tax laws.
 
                                THE DISTRIBUTOR
 
  The Distributor offers one of the industry's broadest lines of investments --
encompassing mutual funds, closed-end funds and unit investment trusts -- and is
currently the nation's 5th largest broker-sold mutual fund group according to
STRATEGIC INSIGHT. Van Kampen American Capital's roots in money management
extend back to 1926. Today, Van Kampen American Capital manages or supervises
more than $50 billion in mutual funds, closed-end funds and unit investment
trusts -- assets which have been entrusted to Van Kampen American Capital in
more than 2 million investor accounts. Van Kampen American Capital has one of
the largest research teams (outside of the rating agencies) in the country, with
86 analysts devoted to various specializations.
 
                                      B-28

  Shares of the Fund are offered on a continuous basis through the Distributor,
One Parkview Plaza, Oakbrook Terrace, IL 60181. The Distributor is a wholly
owned subsidiary of Van Kampen American Capital, Inc., which is a subsidiary of
VK/AC Holding, Inc., a Delaware corporation that is controlled through an
ownership of a substantial majority of its common stock, by The Clayton &
Dubilier Private Equity Fund IV Limited Partnership ("C & D L.P."), a
Connecticut limited partnership. In addition, certain officers, directors and
employees of Van Kampen American Capital, Inc., and its subsidiaries own, in the
aggregate not more than 7% of the common stock of VK/AC Holding, Inc. and have
the right to acquire, upon the exercise of options, approximately an additional
11% of the common stock of VK/AC Holding, Inc. C & D L.P. is managed by Clayton,
Dubilier & Rice, Inc. Clayton & Dubilier Associates IV Limited Partnership ("C &
D Associates L.P.") is the general partner of C & D L.P. Pursuant to a
distribution agreement, the Distributor will purchase shares of the Fund for
resale to the public, either directly or through securities dealers, and is
obligated to purchase only those shares for which it has received purchase
orders. A discussion of how to purchase and redeem the Fund's shares and how the
Fund's shares are priced is contained in the Prospectus.
 
  The public offering price of Class A Shares for purchasers choosing the
initial sales charge alternative is equal to the net asset value plus an initial
sales charge which is a variable percentage of the offering price depending upon
the amount of the sale. The net asset value will be determined as described in
the Prospectus under "Net Asset Value." It is the responsibility of an investor,
or an investor's broker, dealer or financial intermediary, to promptly forward
payment to the Fund for shares being purchased.
 
  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each class of its shares pursuant to Rule 12b-1 under the 1940 Act.
The Fund also has adopted a service plan (the "Service Plan") with respect to
each class of its shares. The Distribution Plan and the Service Plan sometimes
are referred to herein collectively as the Plans. The Plans provide that the
Fund may spend a portion of the Fund's average daily net assets attributable to
each class of shares in connection with distribution of the respective class of
shares and in connection with the provision of ongoing services to shareholders
of such class, respectively. The Plans are being implemented through an
agreement (the "Distribution and Service Agreement") with the Distributor,
distributor of each class of the Fund's shares, sub-agreements between the
Distributor and members of the NASD who are acting as securities dealers and
NASD members or eligible non-members who are acting as brokers or agents and
similar agreements between the Fund and financial intermediaries who are acting
as brokers (collectively, "Selling Agreements") that may provide for their
customers or clients certain services or assistance, which may include, but not
be limited to, processing purchase and redemption transactions, establishing and
maintaining shareholder accounts regarding the Fund, and such other services as
may be agreed to from time to time and as may be permitted by applicable
statute, rule or regulation. Brokers, dealers and financial intermediaries that
have entered into sub-agreements with the Distributor and sell shares of the
Fund are referred to herein as "financial intermediaries."
 
  Under the Distribution and Service Agreement and the Selling Agreements,
financial intermediaries that sold shares prior to July 1, 1987, or prior to the
beginning of the calendar quarter in which the Selling Agreement between the
Fund and such financial intermediary was approved by the Fund's Board of
Trustees (an "Implementation Date") are not eligible to receive compensation
pursuant to such Distribution and Service Agreement or Selling Agreement. To the
extent that there remain outstanding shares of the Fund that were purchased
prior to all Implementation Dates, the percentage of the total average daily net
asset value of a class of shares that may be utilized pursuant to the
Distribution and Service Agreement will be less than the maximum percentage
amount permissible with respect to such class of shares under the Distribution
and Service Agreement.
 
  The Distributor must submit quarterly reports to the Board of Trustees of the
Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Plans and the purposes for which such
expenditures were made, together with such other information as from time to
time is reasonably requested by the Trustees. The Plans provide that they will
continue in full force and effect from year to year so long as such continuance
is specifically approved by a vote of the Trustees, and also by a vote of the
disinterested Trustees, cast in person at a meeting called for the purpose of
voting on the Plans. Each of the Plans may not be amended to increase materially
the amount to be spent for the services described therein
 
                                      B-29
<PAGE>   477
 
with respect to either class of shares without approval by a vote of a majority
of the outstanding voting shares of such class, and all material amendments to
either of the Plans must be approved by the Trustees and also by the
disinterested Trustees. Each of the Plans may be terminated with respect to
either class of shares at any time by a vote of a majority of the disinterested
Trustees or by a vote of a majority of the outstanding voting shares of such
class.
 
  For the year ended December 31, 1994, the Fund has recognized expenses under
the Plans of $2,804,735, $270,245 and $46,842 for the Class A Shares, Class B
Shares and Class C Shares, respectively, of which $2,469,995 and $63,660
represent payments to financial intermediaries under the Selling Agreements for
Class A Shares and Class B Shares, respectively. For the year ended December 31,
1994, the Fund has reimbursed the Distributor $208,207 and $8,129 for
advertising expenses, and $58,830 and $7,493 for compensation of the
Distributor's sales personnel for the Class A Shares and Class B Shares,
respectively.

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

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

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

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


A. Security Valuation-Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in
accordance with procedures established in good faith by the Board of Trustees.
Short-term securities with remaining maturities of less than 60 days are 
valued at amortized cost.


B. Security Transactions-Security transactions are recorded on a trade
date basis. Realized gains and losses are determined on an identified cost
basis. The Fund may purchase and sell securities on a "when issued" and "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Fund will maintain, in a segregated account with its custodian, assets having an
aggregate value at least equal to the amount of the when issued or delayed 
delivery purchase commitments until payment is made.


C. Investment Income-Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of
each applicable security.


D. Federal Income Taxes-It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and
to distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

The Fund intends to utilize provisions of the Federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At December 31, 1994, the Fund had an accumulated capital loss
carryforward for tax purposes of $12,774 which will expire on December 31, 2001.
Net realized gains or losses may differ for financial and tax reporting purposes
primarily as a result of post October 31 losses which are not recognized for tax
purposes until the first day of the following fiscal year.


E. Distribution of Income and Gains-The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes.


F. Insurance Expenses-The Fund typically invests in insured bonds. Any portfolio
securities not specifically covered by a primary insurance policy are insured
secondarily through the Fund's portfolio insurance policy. Insurance premiums
are based on the daily balances of uninsured bonds in the portfolio of
investments and are charged to expense on an accrual basis. The insurance policy
guarantees the timely payment of principal and interest on the securities in the
Fund's portfolio.


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

on most redemptions made within six years of the purchase for Class B and one
year of the purchase for Classes C and D as detailed in the following schedule.

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

4. Investment Transactions

short-term notes, for the year ended December 31, 1994, were $588,246,932 and
$656,359,642, respectively.


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

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

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

Notes to Financial Statements (Continued)

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

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

Transactions in options for the year ended December 31, 1994, were as follows:

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

</TABLE>



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

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

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

                             ---------  ------------
</TABLE>



C. Indexed Securities-These instruments are identified in the portfolio of
investments. The price of these securities may be more volatile than the price
of a comparable fixed rate security.

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

An Embedded Swap security includes a swap component such that the fixed coupon
component of the underlying bond is adjusted by the difference between the
securities fixed swap rate and the floating swap index. As the floating rate
rises, the coupon is reduced. Conversely, as the floating rate declines, the
coupon is increased. These instruments are typically used by the Fund to
enhance the yield of the portfolio.


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

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

MUNICIPAL SECURITIES
 
     Municipal Securities 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-
 
                                        3
<PAGE>   502
 
operated facilities. Such obligations are included within the term Municipal
Securities if the interest paid thereon is exempt from federal income tax.
Municipal Securities 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 Securities are "general
obligations" and "revenue" or "special obligations." General obligations are
secured by the issuer's pledge of 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 other specific
revenue source such as from the user of the facility being financed. Industrial
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 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 in question.
 
     When a 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.
 
     Each 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 for such Fund or if unrated are of comparable
quality as determined by the Adviser. 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. Demand notes may also
include Municipal Securities subject to a Stand-By Commitment as described in
the Prospectus. 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 interests will be tax-exempt when distributed as dividends to shareholders.
 
     Yields on Municipal Securities 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 a Fund to achieve its investment
objective is also dependent on the continuing ability of the issuers of the
Municipal Securities 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 Securities, both within a particular
classification and between classifications, depending on numerous factors.
Furthermore, the rights of holders of Municipal Securities and the obligations
of the issuers of such Municipal Securities 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 of and interest on Municipal Securities.
 
     From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on Municipal Securities. It may be expected that similar proposals may
be introduced in the future. If such a proposal were enacted, the ability of the
Trust to pay "exempt interest" dividends may be adversely affected and the Trust
would re-evaluate its investment objective and policies and consider changes in
its structure.

ADDITIONAL RISKS OF LOWER RATED MUNICIPAL SECURITIES
 
     Additional risks of lower rated Municipal Securities include limited
liquidity and secondary market support. As a result, the prices of lower rated
Municipal Securities may decline rapidly in the event a significant number of
holders decide to sell. Changes in expectations regarding an individual issuer,
an industry or lower rated Municipal Securities generally could reduce market
liquidity for such securities and make their sale by the Fund more difficult, at
least in the absence of price concessions. Reduced liquidity could also create
difficulties in accurately valuing such securities at certain times. The high
yield bond market has grown primarily during a period of long economic expansion
and it is uncertain how it would perform during an economic downturn. An
economic downturn or an increase in interest rates could severely disrupt the
market for high yield bonds and adversely affect the value of outstanding bonds
and the ability of the issuers to repay principal and interest. The Fund will
take such actions as it considers appropriate in the event of anticipated
financial difficulties, default or bankruptcy of either the issuer or any
Municipal Security owned by the Fund or the underlying source of funds for debt
service. Such action may include retaining the services of various persons and
firms to evaluate or protect any real estate, facilities or other assets
securing any such obligation or acquired by the Fund as a result of any such
event. The Fund incurs additional expenditures in taking protective action with
respect to Fund obligations in default and assets securing such obligations.
Investment in lower rated Municipal Securities are not generally meant for
short-term investment.
 
TEMPORARY INVESTMENTS
 
     The taxable securities in which the Funds may invest as temporary
investments include United States Government securities, corporate bonds and
debentures, domestic bank certificates of deposit and bankers' acceptances of
domestic banks with assets of $500 million or more and having deposits insured
by the Federal Deposit Insurance Corporation, commercial paper and repurchase
agreements. In the case of each Fund, the taxable securities are subject to the
same rating requirements applicable to the Municipal Securities in which the
Fund invests, including, in the case of unrated securities, that such
obligations be in the opinion of the Adviser of comparable quality.
 
     United States Government securities include obligations issued or
guaranteed as to principal and interest by the United States Government, its
agencies and instrumentalities which are supported by any of the following: (a)
the full faith and credit of the United States Government, (b) the right of the
issuer to borrow an amount limited to a specific line of credit from the United
States Government, (c) discretionary authority of the United States 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. A Fund may not invest
in any security 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
 
     Each Fund of the Trust 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 Trust) 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
Trust 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 is required to maintain the value
of the underlying securities marked to market daily at not less than the
repurchase price. The underlying securities (securities of the U.S. Government,
or its agencies and instrumentalities), may have maturity dates exceeding one
year. The Trust does not bear the risk of a decline in value of the underlying
security unless the seller defaults under its repurchase obligation. In the
event of a bankruptcy or other default of a seller of a repurchase agreement,
the Trust could experience both delays in liquidating the underlying securities
and loss
 
                                        5
<PAGE>   504
 
including: (a) possible decline in the value of the underlying security during
the period while the Trust 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. A Fund will not invest in repurchase
agreements maturing in more than seven days if any such investment, together
with any other illiquid security owned by such Fund, exceeds ten percent of the
value of its net assets. See "Investment Practices -- Repurchase Agreements" in
the 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, a 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 contract 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 a 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. A 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
 
                                        6
<PAGE>   505
 
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.
 
     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.
 
     A 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
 
                                        7
<PAGE>   506
 
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 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
 
     A Fund could also purchase and write options on futures contracts. An
option on a futures contract gives the purchase 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. A 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 others (regardless of whether such
options are written on the same or different Exchanges or are held or written on
one or more accounts or through one or more brokers). 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 Trust 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 Trust 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 Trust has adopted the following restrictions which, along with its
investment objective, cannot be changed with respect to any Fund without
approval by the holders of a majority of the outstanding shares of such Fund.
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. In
addition to the fundamental investment limitations set forth in the Prospectus,
a Fund shall not:
 
      1. Purchase or hold securities of any issuer if any of the Trust's
         officers or trustees, or officers or directors of its investment
         adviser, who beneficially owns 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, except that a Fund may obtain such
         short-term credits as may be necessary for the clearance of purchases
         and sales of securities. The deposit or payment by the Trust of an
         initial or maintenance margin in connection with futures contracts or

         agreements, utilizing options, futures contracts, options on futures

         considered "senior securities" but for the maintenance by the Trust of
         a segregated account with its custodian or some other form of "cover".
 
     Because of the nature of the securities in which the Trust may invest, no
Fund may invest in voting securities, or invest for the purpose of exercising
control or management, or invest in securities of other investment companies. If
a percentage restriction is satisfied at the time of investment, a later
increase or decrease in such percentage resulting from a change in value will
not constitute a violation of such restriction.

    Dr. Sisto; High Yield Muni, $1,525; Insured Muni, $1,086.
 
(4) Prior to October 6, 1994, Mr. Woodside's compensation was paid by the
    Adviser. As a result, with respect to the second, third and fifth columns,

     Beginning July 21, 1995, the Trust pays each trustee who is not affiliated
with the Adviser, the Distributor or VKAC an annual retainer of $1,562, and $738
and a meeting fee of $45 and $21 per Board meeting plus expenses for High Yield
Municipal Fund and Insured Municipal Fund, respectively. 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 Trust through December 31, 1996 for any increase in the aggregate
trustees' compensation paid by the Trust over their 1994 fiscal year aggregate
compensation.
 
INVESTMENT ADVISORY AGREEMENT
 
     The Trust and the Adviser are parties to an investment advisory agreement
(the "Advisory Agreement"). Under the Advisory Agreement, the Trust retains the
Adviser to manage the investment of its assets and to place orders for the
purchase and sale of its portfolio securities. The Adviser is responsible for
obtaining and evaluating economic, statistical, and financial data and for
formulating and implementing investment programs in furtherance of each Fund's
investment objectives. The Adviser also furnishes at no cost to the Trust
(except as noted herein) the services of sufficient executive and clerical
personnel for the Trust as are necessary to prepare registration statements,
prospectuses, shareholder reports, and notices and proxy solicitation materials.
In addition, the Adviser furnishes at no cost to the Trust the services of a
President of the Trust, one or more Vice Presidents as needed, and a Secretary.
 
     Under the Advisory Agreement, the Trust bears the cost of its accounting
services, which includes maintaining its financial books and records and
calculating the daily net asset value of each Fund. The costs of such accounting
services include the salaries and overhead expenses of a Treasurer or other
principal financial
 
                                       14
<PAGE>   513
 
officer and the personnel operating under his direction. The services are
provided at cost which is allocated among the investment companies advised by
the Adviser. The Trust also pays transfer agency fees, distribution fees,
service fees, custodian fees, legal fees, the costs of reports to shareholders
and all other ordinary expenses not specifically assumed by the Adviser.
 
     Under the Advisory Agreement, the Trust 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 High Yield Municipal
Fund and the Insured Municipal Fund, at an annual rate of 0.60% of the first
$300 million of such Funds' aggregate average net assets, 0.55% of the next $300
million of such Funds' aggregate average net assets and 0.50% of such Funds'
aggregate average net assets in excess of $600 million. Each of the Funds will
pay the same percentage of its average net assets.
 
     The Adviser has entered into a subadvisory agreement (the "Subadvisory
Agreement") with the Subadviser to assist it in performing its investment
advisory function with respect to High Yield Municipal Fund. Pursuant to the
Subadvisory Agreement, the Subadviser receives an annual fee, payable monthly,
of 0.40% of the first $20 million of High Yield Municipal Fund's average daily
net assets, 0.25% of the next $30 million of such Fund's average daily net
assets and 0.15% of the excess over $50 million. The Adviser and Subadviser are
hereinafter referred to as the "Advisers."
 
     The average daily net assets is determined by taking the average of all of
the determinations of the net assets for each business day during a given
calendar month. Such fees are payable for each calendar month as soon as
practicable after the end of that month. The fee payable to the Adviser is
reduced by any commissions, tender solicitation and other fees, brokerage or
similar payments received by the Adviser or any other direct or indirect
majority owned subsidiary of VK/AC Holding, Inc., in connection with the
purchase and sale of portfolio investments of the Trust, less any direct
expenses incurred by such subsidiary of VK/AC Holding, Inc. in connection with
obtaining such payments. The Adviser shall use its best efforts to recapture all
available tender solicitation fees and exchange offer fees in connection with
each of the Trust's transactions and shall advise the Trustees of the Trust 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
Trust's portfolio transactions or other arrangements which may benefit the
Trust.
 
     The Advisory Agreement also provides that, in the event the ordinary
business expenses of the Trust for any fiscal year exceed 0.95% of the average
daily net assets, the compensation due the Adviser will 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 Trust monthly an amount sufficient to
make up the deficiency, subject to readjustment during the year. Ordinary
business expenses do not include (1) interest and taxes, (2) brokerage
commissions, (3) payments made pursuant to distribution plans (described below),
(4) certain litigation and indemnification expenses as described in the Advisory
Agreement, and (5) insurance premiums paid by the Trust to insure the timely
payment of principal and interest on its portfolio obligations. The Advisory
Agreement also provides that the Adviser shall not be liable to the Trust for
any actions or omissions if it acted in good faith without negligence or
misconduct.
 
     For the period ended December 1, 1987 to March 31, 1990, in addition to the
contractual expense limitation, the Adviser elected to reimburse each Fund for
all ordinary business expenses, exclusive of taxes and interest, in excess of
0.85% of the average daily net assets.
 
     The following table shows expenses payable under the Advisory Agreement
during the fiscal years ending November 30, 1992, 1993 and 1994.

     The Advisory Agreement may be continued from year to year if specifically
approved at least annually (a)(i) by the Trust's Trustees or (ii) by vote of a
majority of the Trust'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

penalty by either party on 30 days' written notice.
 
DISTRIBUTOR
 
     The Distributor acts as the principal underwriter of the shares of the
Trust pursuant to a written agreement (the "Underwriting Agreement"). The
Distributor has the exclusive right to distribute shares of each 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 Trust as may be sold to the public. The
Distributor is not obligated to sell any stated number of shares. The
Underwriting Agreement is renewable from year to year if approved (a) by the
Trust's Trustees or by a vote of a majority of the Trust's 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.
 
     For the fiscal years ending November 30, 1992, 1993 and 1994, total
underwriting commissions on the sale of shares of the High Yield Municipal Fund
and Insured Municipal Fund were $3,499,659, $4,146,051, and $2,667,572, and
$531,280, $427,753 and $176,026, respectively. Of such totals, the amount
retained by the Distributor was $226,654, $635,449, and $27,152, and $41,203,
$61,827 and $406,466, respectively. The remainder was reallowed to dealers. Of
such dealer reallowances, $164,406, $168,470, and $81,508, and $62,735, $35,042,
and $8,526, respectively, was received by Advantage Capital Corporation.
 
DISTRIBUTION PLANS
 
     The Trust 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 each 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 Trust 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 Trust
shareholders who are also their clients and/or for distribution. Such payments
are based on an annual percentage of the value of Trust 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
 
                                       16

accounts. With respect to the Class B and Class C Plans, authorized payments by
the Trust 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 Trust also include payments at an
annual rate of up to 0.75% of the net assets of the Class B shares of each Fund
to reimburse the Distributor for (1) commissions and transaction fees of up to
four percent 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,

paid to broker-dealers and other Service Organizations in an amount up to 0.75%
of the average daily net assets of the Trust'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 one and one half percent 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 does not believe that termination of a relationship with a bank
would result in any material adverse consequences to the Trust. 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 the forms 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 Trust 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 each Plan 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 Trust's 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, the Plans 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
the Independent Trustees.
 
     Each Plan may be terminated by vote of a majority of the Independent
Trustees, or by a vote of a majority of the outstanding voting shares of the
respective class of any Fund. Any change in any of the Plans that would
materially increase the distribution or service expenses borne by the Trust
requires shareholder approval, voting separately by class of any Fund;
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
 
                                       17
<PAGE>   516
 
voting upon such amendment. So long as the Plans are in effect, the selection or
nomination of the Independent Trustees is committed to the discretion of the
Independent Trustees.
 
     For the fiscal year ending November 30, 1994, the High Yield Municipal
Fund's and Insured Municipal Fund's gross aggregate expenses under the Class A
Plan were $1,029,318 and $180,174, or 0.25% and 0.24%, respectively, of the
Funds' average daily net assets. Such expenses were paid to reimburse the
Distributor for payments made to Service Organizations for servicing Trust
shareholders and administering the Class A Plan.
 
     For the fiscal year ended November 30, 1994, the aggregate expenses under
the Class B Plan for the High Yield Fund and the Insured Municipal Fund were
$1,335,592 and $378,659, or 1.00% and 1.00%, respectively, of the Funds' average
daily net assets. Such expenses were paid to reimburse the Distributor for the
following payments: $1,001,694 and $283,994, respectively, for commissions and
transaction fees paid to broker-dealers and other Service Organizations in
respect of sales of Class B shares of the Trust and $333,898 and $94,665,
respectively, for fees paid to Service Organizations for servicing Class B
shareholders and administering the Class B Plan.
 
     The offering of Class C shares commenced on December 10, 1993. For the
fiscal year ended November 30, 1994, the aggregate expenses under the Class C
Plan for the High Yield Fund and the Insured Municipal Fund were $65,351 and
$15,952, or 0.97% and 0.97%, respectively, of the Funds' average daily net
assets. Such expenses were paid to reimburse the Distributor for the following
payments: $49,013 and $11,964, respectively, for the commissions and transaction
fees paid to broker-dealers and other Service Organizations in respect of sales
of Class C shares of the Trust and $16,338 and $3,988 respectively, for fees
paid to Service Organizations for servicing Class C shareholders and
administering the Class C Plan.
 
TRANSFER AGENT
 
     During the fiscal year ended November 30, 1994, ACCESS, shareholder service
agent and dividend disbursing agent for the Trust, received fees aggregating
$561,481 and $92,670 from the High Yield Municipal Fund and Insured Municipal
Fund, respectively. These services are provided at cost plus a profit.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
 
     The Advisers are responsible for decisions to buy and sell securities for
the Trust 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 Trust are principal transactions at net prices, the Trust incurs little or
no brokerage costs except for commissions paid with respect to transactions in
future contracts and options. Fund 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 Advisers are responsible for placing portfolio transactions and do so
in a manner deemed fair and reasonable to the Trust 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 Advisers consider
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, consideration may be given to firms which also provide research
services to the Trust or the Advisers. No specific value can be assigned to such
research services which are furnished without cost to the Advisers. The
investment advisory fee is not reduced as a result of the Advisers' receipt of
such research services. Services provided may include (a) furnishing advice as
to the value of the 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 Trust effects
its securities transactions may be used by the Advisers in
 
                                       18
<PAGE>   517
 
servicing all of their advisory accounts; not all of such services may be used
by the Advisers in connection with the Trust.
 
     Consistent with the Rules of Fair Practice of the National Association of
Securities Dealers, Inc. and subject to seeking best execution of such other
policies as the Trustees may determine, the Advisers may consider sales of
shares of the Trust as a factor in the selection of firms to execute portfolio
transactions for the Trust.
 
     The Advisers place portfolio transactions for other advisory accounts
including other investment companies. The Advisers seek to allocate portfolio
transactions equitably whenever concurrent decisions are made to purchase or
sell securities by the Trust 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 Trust. In making such allocations among the Trust and other
advisory accounts, the main factors considered by the Advisers 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 the Trustees of the Trust who are not
interested persons (as defined in the 1940 Act) of the Adviser.
 
     During the fiscal years ended November 30, 1992, 1993 and 1994, the High
Yield Municipal Fund paid $17,325, $5,481 and $79,957, respectively, in
brokerage commissions on portfolio transactions and Insured Municipal Fund paid
no 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.
 
     The Trust conducted no affiliated brokerage transactions through affiliated
brokers during the last three fiscal years.
 
DETERMINATION OF NET ASSET VALUE
 
     The net asset value of the shares of each Fund is computed by dividing the
value of all securities held by the Fund plus other assets, less liabilities
(including accrued expenses), by the number of shares outstanding. Such
computation is made as of the close of the New York Stock Exchange (currently
4:00 p.m., New York time) on each business day on which the New York Stock
Exchange is open. The New York Stock 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.
 
     Each Fund's investments in bonds are valued by an independent pricing
service ("Service"). When, in the judgment of the Service, quoted bid prices for
bonds are readily available and are representative of the bid side of the
market, these bonds are valued at such quoted bid prices (as obtained by the
Service from dealers in such securities). Other bonds 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. Options are valued at the last sale price or, if no
sales are reported, at the mean between the bid and asked prices. Any bonds
which are not valued by the independent pricing service would be valued at fair
value using methods determined in good faith by the Trustees. Expenses and fees,
including the investment advisory fee are accrued daily and taken into account
for the purpose of determining the net asset value of shares of each Fund.
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 of any Fund 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").
 
                                       19

PURCHASE AND REDEMPTION OF SHARES
 
     The following information supplements that set forth in the Trust's
Prospectus under the heading "Purchase of Shares."
 
PURCHASE OF SHARES
 
     Each Fund's shares 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 Trust issues three classes of shares for each Fund: 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 Trust, 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, distribution fees, 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 Securities Act of 1933.
 
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 any Fund, in the form
of a check payable to the Trust, 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
investments are made at the public offering price of the Fund's 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 Trust will act in the same
capacity 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 under "Sales Charge Table" apply to purchases of Class A shares
of each 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 purchaser, as is a trustee or other fiduciary purchasing
for a single fiduciary account. An aggregate investment includes all shares of
the Trust 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 Trust 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 Trust, the charge applicable to the $65,000
purchase would be four percent 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
 
                                       20
<PAGE>   519
 
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 represented 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
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. If 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 Trust, the amount of excess sales charges, if any,
paid during the 13-month period.
 
REDEMPTION OF SHARES
 
     Redemptions are not made on days during which the New York Stock 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 New York Stock
Exchange is closed for other than customary weekends or holidays; (b) trading on
the New York Stock Exchange is restricted; (c) an emergency exists as a result
of which disposal by the Trust of securities owned by it is not reasonably
practicable or it is not reasonably practical for the Trust 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 Trust ("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 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.
 
                                       21
<PAGE>   520
 
     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 herein under "Purchase and 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 may be waived on redemptions of Class B and Class
C shares in the circumstances described below:
 
     (a) Redemption Upon Disability or Death
 
     The Trust 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 Trust 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 or C will be waived
where the descendent 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 or C applies to a total or 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 Trust 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 may 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 Trust 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 Trust 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 Trust's Systematic Withdrawal Plan
 
     A shareholder may elect to participate in a systematic withdrawal plan (the
"Plan") with respect to the shareholder's investment in the Trust. Under the
Plan, a dollar amount of a participating shareholder's investment in the Trust
will be redeemed systematically by the Trust 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.
 
                                       22
<PAGE>   521
 
     The amount of the shareholder's investment in a Trust at the time the
election to participate in the Plan is made with respect to the Trust 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 Trust 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 Trust 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 Trust will waive the CDSC -- Class B and C
upon such involuntary redemption.
 
     (e) Reinvestment of Redemption Proceeds in Shares of the Same Trust Within
         120 Days After Redemption
 
     A shareholder who has redeemed Class C shares of a Trust may reinvest at
net asset value, 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 Class C shares of the Trust, 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 Trust. 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 Trust 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 Trust.
 
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 Trust 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 Trust will be liable for following
telephone instructions which it reasonably believes to be genuine. Van Kampen
American Capital and the Trust 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
 
                                       23
<PAGE>   522
 
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 and return both documents 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, partnership 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, state and
local tax considerations generally affecting the Funds and their shareholders
that are not described in the Prospectus. No attempt is made to present a
detailed explanation of the tax treatment of a 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.
 
GENERAL
 
     By maintaining its qualification as a "regulated investment company" under
the Internal Revenue Code, a Fund will not incur any liability for federal
income taxes to the extent its taxable ordinary income and any capital gain net
income are distributed in accordance with Subchapter M of the Code.
 
     A 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. Each Fund intends to distribute sufficient amounts to avoid liability for
the excise tax. By qualifying as a regulated investment company, a 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 a 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 Trust 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 on
the basis of the subsequent shares.
 
     The Code permits a regulated investment company whose assets consist
primarily of tax-exempt Municipal Securities to pass through to its investors,
tax-exempt, net Municipal Securities interest income. In order for a 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
income" (i.e., its
 
                                       24
<PAGE>   523
 
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").
 
     Not later than 60 days after the close of its taxable year, each 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 Fund
shareholders as items of interest excluded from their gross income, each
shareholder is advised to consult his tax adviser with respect to whether
exempt-interest dividends retain this exclusion if the purchaser would be
treated as a "substantial user" or a "related person" with respect to any of the
tax-exempt obligations held by the Fund, or by the Trust if it is required to
qualify as a regulated investment company as described below. "Substantial user"
is defined under U.S. Treasury Regulations to include a non-exempt person who
regularly uses in his trade or business a part of any facilities financed with
the tax-exempt obligations and whose gross revenues derived from such facilities
exceed five percent of the total revenues derived from the facilities by all
users, or who occupies more than five percent of the useable area of the
facilities or for whom the facilities or a part thereof were specifically
constructed, reconstructed or acquired. Examples of "related persons" include
certain related natural persons, affiliated corporations, a partnership and its
partners and an S corporation and its shareholders.
 
     Interest on indebtedness incurred by a shareholder to purchase or carry
shares of a Fund is not deductible for federal income tax purposes if the Fund
distributes exempt-interest dividends during the shareholder's taxable year. If
a shareholder receives an exempt-interest dividend with respect to any shares
and such shares are held for six months or less, any short-term capital loss on
the sale or exchange of the shares will be disallowed to the extent of the
amount of such exempt-interest dividend.
 
     If, during any taxable year, a 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 Securities 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 shares of any
one of the Funds 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.
 
TAX TREATMENT OF FUTURES CONTRACTS AND RELATED OPTIONS
 
     In connection with its operations, a 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 a 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 a Fund, any realized gain
or loss will be treated as long-term capital gain or loss to the extent of 60%
thereof and short-term capital gain or loss to the extent of 40%
 
                                       25
<PAGE>   524
 
thereof (hereinafter "60/40 gain or loss"). Open Futures Contracts held by a
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 Futures Contracts. The Distribution
Requirements may limit a Fund's ability to hold Futures Contracts and Futures
Options at the end of a year.
 
     A portion of a 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 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 a 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. No determination has been made whether any Fund
will make any of these elections.
 
     A 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 Trust 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 Trust. 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 that of counsel. Counsel has also advised the Trust 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, a 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 a 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 the Trust 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 the Trust's assets may be invested
in the securities of any one issuer and at least 50% of the value of the Trust'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
Trust. Consequently, the Trust's ability to invest in Futures Contracts and
Futures Options may be limited.
 
TREATMENT OF DIVIDENDS
 
     While each Fund expects that a major portion of its investment income will
constitute tax-exempt interest, a significant portion may consist of "investment
company taxable income" and "net capital gains." As pointed out above, a Fund
will be subject to tax for any year on its undistributed investment company
taxable income and net capital gains.
 
                                       26
<PAGE>   525
 
     It is anticipated that substantially all of a 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. Distributions
that are not designated as capital gain dividends will be taxable to
shareholders as ordinary income. Dividends and distributions declared payable 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 a Fund's net investment income arises from dividends on
common or preferred stock, none of its distributions are eligible for the 70%
dividends received deduction available to corporations.
 
     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 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 Trust
shares.
 
BACK-UP WITHHOLDING
 
     The Trust 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 Trust shares with respect to any shareholder who is not
exempt from withholding and who fails to furnish the Trust with a correct
taxpayer identification number, who fails to report fully dividend or interest
income or who fails to certify to the Trust 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.
 
TRUST PERFORMANCE
 
     The average annual total return for Class A shares of each Fund for the
one-year, five-year and eight-year periods ending November 30, 1994 was -4.68%,
5.83% and 6.11% for the High Yield Municipal Fund, and - 8.47%, 4.44% and 4.61%
for the Insured Municipal Fund, respectively. Results from inception through
April 1, 1990, reflect expense reimbursement described under "Investment
Advisory Agreement." The average annual total return for Class B shares of each
Fund one-year period and the 28 month period ending November 30, 1994, was
- -4.49% and 2.80% for the High Yield Municipal Fund and -8.24% and 0.48% for the
Insured Municipal Fund, respectively. The aggregate total return for Class C
shares of each Fund for the period December 10, 1993 through November 30, 1994
was -2.73% and -6.29% for the High Yield Municipal Fund and Insured Municipal
Fund, respectively. 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 objectives
and policies as well as the risks incurred in the Fund's investment practices.
 
     The following chart lists the High Yield Municipal Fund's and Insured
Municipal Fund's annualized current yield and tax equivalent yield for the
30-day period ending November 30, 1994.

     Neither the High Yield Municipal Fund's nor the Insured Municipal Fund's
yield is 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, Fund 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 VKAC will announce the results of its monthly polls of
U.S. investor intentions -- the Van Kampen American Capital Index of Investor
Intentions and the Van Kampen American Capital Mutual Fund Index -- which polls
measure how Americans plan to use their money.
 
     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.
 
     The Funds 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 Funds.
 
OTHER INFORMATION
 
     Dividends and Distributions -- Shareholders are informed as to the sources
of distributions at the time of payment. Any capital gain distribution paid
shortly after a purchase of shares by an investor will have the effect of
reducing the per share net asset value of the shares owned by the amount of the
distribution. See "Distributions from the Fund" in the Prospectus for further
information.
 
     Custody of Assets -- All securities owned by the Trust and all cash,
including proceeds from the sale of shares of the Trust and of securities in the
Trust's investment portfolios, are held by State Street Bank and Trust Company,
225 Franklin Street, Boston, Massachusetts 02110, as Custodian.
 
     Shareholder Reports -- Semi-annual statements are furnished to
shareholders, and annually such statements are audited by the independent
accountants.
 
     Independent Accountants -- Price Waterhouse LLP, 1201 Louisiana, Houston,
Texas 77002, the independent accountants for the Trust, performs an annual audit
of the Trust's financial statements.
 
FINANCIAL STATEMENTS
 
     The attached financial statements in the form in which they appear in the
Annual Report to Shareholders, including the related Report of Independent
Accountants on the November 30, 1994 Financial Statements are included in the
Statement of Additional Information.
 
     Set forth below is an example of the method of computing the offering price
of the Trust's Class A shares. The example assumes a purchase of Class A shares
of a Fund aggregating less than $100,000 subject to the schedule of sales
charges set forth in the Prospectus at a price based upon the net asset value of
Class A shares of such Fund on November 30, 1994.

                             RATINGS OF INVESTMENTS
 
RATINGS OF MUNICIPAL BONDS
 
DESCRIPTIONS OF MOODY'S INVESTORS SERVICE ("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.
 
     Caa -- Bonds which are rated Caa are of poor standing. Such issues may be
in default or there may be present elements of danger with respect to principal
or interest.
 
     Ca -- Bonds which are rated Ca represent obligations which are speculative
in a high degree. Such issues are often in default or have other marked
shortcomings.
 
     C -- Bonds which are rated C are the lowest rated class of bonds and issues
so rated can be regarded as having extremely poor prospects of ever attaining
any real investment standing.
 
     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
 
                                       29
<PAGE>   528
 
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 in 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
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 the following three designations, all
judged to be investment grade, to indicate the relative repayment capacity of
rated issuers:
 
          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.
 
          Issuers rated Prime-3 (or related supporting institutions) have an
     acceptable capacity for repayment of short-term promissory obligations.
 
          Issuers rated Not Prime do not fall within any of the Prime rating
     categories.
 
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S MUNICIPAL ("S&P") 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 it is somewhat more susceptible to the adverse
           effects of changes in circumstances and economic conditions than debt
           in higher-rated categories.
 
      BBB Debt rated "BBB" is regarded as having an adequate capacity to pay
          interest and repay principal. Whereas it normally exhibits adequate
          protection parameters, adverse economic conditions or changing
          circumstances are more likely to lead to a weakened capacity to pay
          interest and repay principal for debt in this category than for debt
          in higher-rated categories.
 
     BB-B-CCC-CC-C
          Debt rated "BB", "B", "CCC", "CC" or "C" 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 and "C" the highest degree
          of speculation. While such debt will likely have some quality and
          protective characteristics, these are outweighed by large
          uncertainties or major risk exposures to adverse conditions.
 
        CI This rating is reserved for income bonds on which no interest is
           being paid.
 
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 Standard & Poor's 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.
Ratings are graded into four categories, ranging from "A" for the highest
quality obligations to "D" for the lowest. Ratings are applicable to both
taxable and tax-exempt commercial paper. The four categories are as follows:
 
     A Issues assigned this highest rating are regarded as having the greatest
       capacity for timely payment. Issues in this category are further refined
       with the designation 1, 2 and 3 to indicate the relative degree of
       safety.
 
       A-1 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".
 
       A-3 Issues carrying this designation have a satisfactory capacity for
           timely payment. They are, however, somewhat more vulnerable to the
           adverse effects of changes in circumstances than obligations carrying
           the higher designations.
 
     B Issues rated "B" are regarded as having only an adequate capacity for
       timely payment. However, such capacity may be damaged by changing
       conditions or short-term adversities.
 
     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
 
                                       31
<PAGE>   530
 
considers reliable. The ratings may be changed, suspended, or withdrawn as a
result of changes in or unavailability of, such information.
 
     S&P ratings of certain municipal note issues with a maturity of less than
three years 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.

Note 1-Significant Accounting Policies

American Capital Tax-Exempt Trust (the "Fund") is comprised of two municipal
bond portfolios: High Yield Municipal Portfolio ("High Yield") and Insured
Municipal Portfolio ("Insured"), and is registered under the Investment
Company Act of 1940, as amended, as a diversified open-end management
investment company.

Each portfolio is accounted for as a separate entity. The following is a
summary of significant accounting policies consistently followed by the Fund
in the preparation of its financial statements.

A.     Investment Valuations

       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. Securities for which market
       quotations are not readily available are valued at a fair value as
       determined in good faith by the Board of Directors of the Fund.
       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.

       High yield investments include lower rated and unrated debt securities
       which may be more susceptible to adverse economic conditions than
       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. Securities
       rated below investment grade and comparable unrated securities
       represented approximately 74% of High Yield's investment portfolio at
       November 30, 1994.

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

B.     Repurchase Agreements

       A repurchase agreement is a short-term investment in which a Fund
       acquires ownership of a debt security and the seller agrees to
       repurchase the security at a future time and specified price. The Fund
       may invest independently in repurchase agreements, or transfer
       uninvested cash balances into a pooled cash account along with other
       investment companies advised by Van Kampen American Capital Asset
       Manager, Inc. ("The Adviser"), the daily aggregate of which is invested
       in repurchase agreements. Repurchase agreements are collateralized by
       the underlying debt securities. The Fund will make payment for such
       securities only upon physical delivery or evidence of book entry
       transfer to the account of the custodian bank. The seller is required to
       maintain the value of the underlying security at not less than the
       repurchase proceeds due the Fund.

C.     Futures Contracts

       Transactions in futures contracts are utilized in strategies to manage
       the market risk of the Fund's investments by increasing or decreasing
       the percentage of assets effectively invested. The purchase of a futures
       contract increases the impact of changes in the market price of
       investments on net asset value. There is also a risk that the market
       movement of such instruments may not be in the direction forecasted.

       Upon entering into futures contracts, the Fund maintains, in a
       segregated account with its custodian, securities with a value equal to
       its obligation under the futures contracts. A portion of these funds is
       held as collateral in an account in the name of the broker, the Fund's
       agent in acquiring the futures position. During the period the futures
       contract is open, changes in the value of the contract ("variation
       margin") are recognized by marking the contract to market on a daily
       basis. As unrealized gains or losses are incurred, variation margin
       payments are received from or made to the broker. Upon the closing or
       cash settlement of a contract, gains and losses are realized. The cost
       of securities acquired through delivery under a contract is adjusted by
       the unrealized gain or loss on the contract.

D.     Federal Income Taxes
 
       No provision for federal income taxes is required because the Fund has
       elected to be taxed as "regulated investment companies" 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 capital gains will be made until
       tax basis capital loss carryforwards, if any, expire or are offset by 
       net realized capital gains.

E.     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.

F.     Dividends and Distributions

       The Fund declares dividends from net investment income of each portfolio
       on each business day. The Fund intends to continue to invest principally
       in tax-exempt obligations sufficient in amount to qualify it to pay
       "exempt-interest dividends" as defined in the Internal Revenue Code.

       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 a portfolio's financial statement earnings.

G.     Debt Discount or Premium

       The Fund accounts for discounts and premiums on the same basis as is
       used for federal income tax reporting. Accordingly, original issue debt
       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.

H.     When-Issued Securities

       Delivery and payment for securities purchased on a when-issued basis may
       take place up to 45 days after the day of the transaction. The
       securities purchased are subject to market fluctuation during this
       period. To meet the payment obligations, 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

The Adviser serves as the investment manager of the Fund. Management fees are
paid monthly, based on the aggregate average daily net assets of the Fund at an
annual rate of .60% of the first $300 million of the aggregate average daily
net assets, .55% of the next $300 million, and .50% of the amount in excess of
$600 million, and are allocated on a pro-rata basis to each portfolio. From
time to time, the Adviser may voluntarily elect to subsidize a portion of the
Fund's expenses. The voluntary subsidy may be discontinued at any time without
prior notice. There were no subsidies during the fiscal year ended November 30, 
1994.

Other transactions with affiliates during the year were as follows:

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.
These charges included 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. These services provided by the
Adviser are at cost.

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

Van Kampen American Capital Shareholder Services, Inc., an affiliate of the
Adviser, serves as the Fund's shareholder service agent. These services are
provided at cost plus a profit.

The Fund was informed that Van Kampen American Capital Distributors, Inc.
(the "Distributor") and Advantage Capital Corporation (the "Retail Dealer"),
both affiliates of the Adviser, received commissions charged on sales of Fund
shares during the year.

Under the terms of the Distribution plans, each portfolio pays up to .25% per
annum of its average daily net assets to reimburse the Distributor for
expenses and service fees incurred. Class B and Class C shares pay an
additional distribution fee of up to .75% per annum of their average net
assets to reimburse the Distributor for its distribution expenses. Actual
distribution expenses incurred by the Distributor for Class B and Class C
shares may exceed the amounts reimbursed to the Distributor by the portfolios.
At November 30, 1994, the unreimbursed expenses by the Distributor under the
Class B and Class C plans aggregated approximately $5.8 million and $126,000,
respectively, for High Yield and approximately $1.5 million and $36,000,
respectively, for Insured 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
reimbursements of distribution fees.

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

</TABLE>

The net realized capital loss carryforwards at November 30, 1994 may be
utilized to offset any future capital gains until expiration from 1995 
through 2002. Additionally, approximately $1 million of financial 
statement capital losses for High Yield are deferred for tax purposes 
to the 1995 fiscal year.

At November 30, 1994, High Yield held 405 short United States Treasury Bond
financial futures contracts expiring in March 1995. The market value of such
contracts at November 30, 1994 was $39,715,313 and the unrealized
depreciation was $506,300.

During the year, the cost of purchases and proceeds from sales of investments
resulting from transactions between High Yield, Insured and other investment 
companies advised by the Adviser were:

      Deferred compensation liability...........      10,326             7,238
</TABLE>

Trustees who are not affiliated with the Adviser are compensated by the Fund at
the annual rate of $2,510 plus a fee of $65 per day for the Board and Committee
meetings attended. The Chairman receives additional fees at an annual rate of
$940. The trustees 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 general accounts. Funds for the payment of obligations
under the Plan will not be reserved or set aside by any form of trust or
escrow. Each director covered by the Plan has elected 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

Each portfolio 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 a higher distribution services fee 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. 

Each portfolio has an unlimited number of $.01 par value shares of beneficial 
interest authorized. Transactions in shares of beneficial interest were as 
follows:

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Board of Trustees of American Capital Tax-Exempt Trust

In our opinion, the accompanying statements of assets and liabilities,
including the investment portfolios of High Yield Municipal Portfolio and
Insured Municipal 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 each of the two portfolios
constituting American Capital Tax-Exempt Trust (the "Trust") at November 30,
1994, the results of each of their operations for the year then ended, the
changes in each of their net assets for each of the two years in the period
then ended and the selected per share data and ratios for each of the 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 reponsibility of the Trust'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 obtian reasonable assurance about whether the
financial statements are free of material misstatements. 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 November 30, 1994 by correspondence with the custodian and
brokers, provide a reasonable basis for the opinon expressed above.

VAN KAMPEN MERRITT INSURED TAX FREE INCOME FUND
NOTES TO FINANCIAL STATEMENTS
December 31, 1994
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
     Van Kampen Merritt Insured Tax Free Income Fund (the "Fund") was
incorporated under Maryland law on July 1, 1984, and is registered as a
diversified open-end management investment company under the Investment Company
Act of 1940, as amended. The Fund commenced investment operations on December
14, 1984 and was reorganized as a sub-trust of Van Kampen Merritt Tax Free Fund
(the "Trust"), a Massachusetts business trust as of February 22, 1988. On May 1,
1993, the Fund commenced the distribution of its Class B shares. The
distribution of the Fund's Class C shares, which were initially introduced as
Class D shares and subsequently renamed Class C shares on March 7, 1994,
commenced on August 13, 1993. The distribution of the Fund's fourth class of
shares, Class D shares, commenced on March 14, 1994.
 
     The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements.
 
     A. Security Valuation -- Investments are stated at value using market
quotations or, if such valuations are not available, estimates obtained from
yield data relating to instruments or securities with similar characteristics in
accordance with procedures established in good faith by the Board of Trustees.
Short-term securities with remaining maturities of less than 60 days are valued
at amortized cost.
 
     B. Security Transactions -- Security transactions are recorded on a trade
date basis. Realized gains and losses are determined on an identified cost
basis. The Fund may purchase and sell securities on a "when issued" and "delayed
delivery" basis, with settlement to occur at a later date. The value of the
security so purchased is subject to market fluctuations during this period. The
Fund will maintain, in a segregated account with its custodian, assets having an
aggregate value at least equal to the amount of the when issued or delayed
delivery purchase commitments until payment is made.
 
     C. Investment Income -- Interest income is recorded on an accrual basis.
Bond premium and original issue discount are amortized over the expected life of
each applicable security.
 
     D. Federal Income Taxes -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no provision for federal income taxes is required.
 
     The Fund intends to utilize provisions of the Federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At December 31, 1994, the Fund had an accumulated capital loss
carryforward for tax purposes of $12,774 which will expire on December 31, 2001.
Net realized gains or losses may differ for financial and tax reporting purposes
primarily as a result of post October 31 losses which are not recognized for tax
purposes until the first day of the following fiscal year.
 
     E. Distribution of Income and Gains -- The Fund declares daily and pays
monthly dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes.

     F. Insurance Expenses -- The Fund typically invests in insured bonds. Any
portfolio securities not specifically covered by a primary insurance policy are
insured secondarily through the Fund's portfolio insurance policy. Insurance
premiums are based on the daily balances of uninsured bonds in the portfolio of
investments and are charged to expense on an accrual basis. The insurance policy
guarantees the timely payment of principal and interest on the securities in the
Fund's portfolio.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
 
     Under the terms of the Fund's Investment Advisory Agreement, Van Kampen
American Capital Investment Advisory Corp. (the "Adviser") will provide
investment advice and facilities to the Fund for an annual fee payable monthly

counsel to the Fund, of which a trustee of the Fund is an affiliated person.
 
     For the year ended December 31, 1994, the Fund recognized expenses of
approximately $654,500 representing Van Kampen American Capital Distributors,
Inc.'s or its affiliates' ("VKAC") cost of providing accounting, legal and
certain shareholder services to the Fund.
 
     Certain officers and trustees of the Fund are also officers and directors
of VKAC. The Fund does not compensate its officers or trustees who are officers
of VKAC.
 
     The Fund has implemented deferred compensation and retirement plans for its
Trustees. Under the deferred compensation plan, Trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those Trustees who are not officers of VKAC.
 
     At December 31, 1994, VKAC owned 100 shares each of Classes B, C and D.
 
3. CAPITAL TRANSACTIONS
 
     The Fund has outstanding four classes of common shares, Classes A, B, C and

     For the year ended December 31, 1994, VKAC, as Distributor for the Fund,
received net commissions on sales of the Fund's Class A shares of approximately
$648,100 and CDSC on the redeemed shares of Classes B, C and D of approximately
$56,300. Sales charges do not represent expenses of the Fund.
 
4. INVESTMENT TRANSACTIONS
 
     Aggregate purchases and cost of sales of investment securities, excluding
short-term notes, for the year ended December 31, 1994, were $588,246,932 and
$656,359,642, respectively.
 
5. DERIVATIVE FINANCIAL INSTRUMENTS
 
     A derivative financial instrument in very general terms refers to a
security whose value is "derived" from the value of an underlying asset,
reference rate or index.
 
     The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective yield, maturity and duration.
All of the Fund's portfolio holdings, including derivative instruments, are
marked to market each day with the change in value reflected in the unrealized
appreciation/depreciation on investments. Upon disposition, a realized gain or
loss is recognized accordingly, except for exercised option contracts where the
recognition of gain or loss is postponed until the disposal of the security
underlying the option contract.
 
     Summarized below are the specific types of derivative financial instruments
used by the Fund.
 
     A. Option Contracts -- An option contract gives the buyer the right, but
not the obligation to buy (call) or sell (put) an underlying item at a fixed
exercise price during a specified period. These contracts are generally used by
the Fund to manage the portfolio's effective maturity and duration.
 
     Transactions in options for the year ended December 31, 1994, were as
follows:

</TABLE>
 
     B. Futures Contracts -- A futures contract is an agreement involving the
delivery of a particular asset on a specified future date at an agreed upon
price. The Fund generally invests in futures on U.S. Treasury Bonds and the
Municipal Bond index and typically closes the contract prior to the delivery
date. These contracts are generally used to manage the portfolio's effective
maturity and duration.
 
     The fluctuation in market value of the contracts is settled daily through a
cash margin account. Realized gains and losses are recognized when the contracts
are closed or expire.

</TABLE>
 
     C. Indexed Securities -- These instruments are identified in the portfolio
of investments. The price of these securities may be more volatile than the
price of a comparable fixed rate security.
 
     An Inverse Floating security is one where the coupon is inversely indexed
to a short-term floating interest rate multiplied by a specified factor. As the
floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. These instruments are typically used by the
Fund to enhance the yield of the portfolio.
 
     An Embedded Swap security includes a swap component such that the fixed
coupon component of the underlying bond is adjusted by the difference between
the securities fixed swap rate and the floating swap index. As the floating rate
rises, the coupon is reduced. Conversely, as the floating rate declines, the
coupon is increased. These instruments are typically used by the Fund to enhance
the yield of the portfolio.
 
6. DISTRIBUTION AND SERVICE PLANS
 
     The Fund and its shareholders have adopted a distribution plan (the
"Distribution Plan") pursuant to Rule 12b-1 under the Investment Company Act of
1940 and a service plan (the "Service Plan," collectively the "Plans"). The
Plans govern payments for the distribution of the Fund's shares, on going
shareholder services and maintenance of shareholder accounts.
 
     Annual fees under the Plans of up to .30% each of Class A and Class D
shares and 1.00% each of Class B and Class C shares are accrued daily. Included
in these fees for the year ended December 31, 1994, are payments to VKAC of
approximately $512,700.

portfolio of investments, as of December 31, 1994, and the related statement of
operations for the year then ended, the statement of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each of the periods presented. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1994, by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of Van
Kampen Merritt Insured Tax Free Income Fund as of December 31, 1994, the results
of its operations for the year then ended, the changes in its net assets for

AMERICAN CAPITAL TAX-EXEMPT
INSURED MUNICIPAL PORTFOLIO
 
NOTES TO FINANCIAL STATEMENTS
 
NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES
 
     American Capital Tax-Exempt Insured Municipal Portfolio (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
 
   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. Securities for which market quotations are not
   readily available are valued at a fair value as determined in good faith by
   the Board of Directors of the Fund. 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 at maturity and interest. The
   insurance reduces credit risk but not market risk of the security.
 
B. REPURCHASE AGREEMENTS
 
   A repurchase agreement is a short-term investment in which a Fund acquires
   ownership of a debt security and the seller agrees to repurchase the security
   at a future time and specified price. The Fund may invest independently in
   repurchase agreements, or transfer uninvested cash balances into a pooled
   cash account along with other investment companies advised by Van Kampen
   American Capital Asset Manager, Inc. ("The Adviser"), the daily aggregate of
   which is invested in repurchase agreements. Repurchase agreements are
   collateralized by the underlying debt securities. The Fund will make payment
   for such securities only upon physical delivery or evidence of book entry
   transfer to the account of the custodian bank. The seller is required to
   maintain the value of the underlying security at not less than the repurchase
   proceeds due the Fund.
 
C. FUTURES CONTRACTS
 
   Transactions in futures contracts are utilized in strategies to manage the
   market risk of the Fund's investments by increasing or decreasing the
   percentage of assets effectively invested. The purchase of a futures contract
   increases the impact of changes in the market price of investments on net
   asset value. There is also a risk that the market movement of such
   instruments may not be in the direction forecasted.
 
   Upon entering into futures contracts, the Fund maintains, in a segregated
   account with its custodian, securities with a value equal to its obligation
   under the futures contracts. A portion of these funds is held as collateral
   in an account in the name of the broker, the Fund's agent in acquiring the
   futures position.

NOTES TO FINANCIAL STATEMENTS -- CONTINUED
 
   During the period the futures contract is open, changes in the value of the
   contract ("variation margin") are recognized by marking the contract to
   market on a daily basis. As unrealized gains or losses are incurred,
   variation margin payments are received from or made to the broker. Upon the
   closing or cash settlement of a contract, gains and losses are realized. The
   cost of securities acquired through delivery under a contract is adjusted by
   the unrealized gain or loss on the contract.
 
D. FEDERAL INCOME TAXES
 
   No provision for federal income taxes is required because the Fund has
   elected to be taxed as "regulated investment companies" 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 capital gains will be made until tax basis capital loss
   carryforwards, if any, expire or are offset by net realized capital gains.
 
E. 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.
 
F. DIVIDENDS AND DISTRIBUTIONS
 
   The Fund declares dividends from net investment income on each business day.
   The Fund intends to continue to invest principally in tax-exempt obligations
   sufficient in amount to qualify it to pay "exempt-interest dividends" as
   defined in the Internal Revenue Code.
 
   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.
 
G. DEBT DISCOUNT OR PREMIUM
 
   The Fund accounts for discounts and premiums on the same basis as is used for
   federal income tax reporting. Accordingly, original issue debt 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.
 
H. WHEN-ISSUED SECURITIES
 
   Delivery and payment for securities purchased on a when-issued basis may take
   place up to 45 days after the day of the transaction. The securities
   purchased are subject to market fluctuation during this period. To meet the
   payment obligations, 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
 
     The Adviser serves as the investment manager of the Fund. Management fees
are paid monthly, based on the aggregate average daily net assets of the Fund at
an annual rate of .60% of the first $300 million of the aggregate average daily
net assets, .55% of the next $300 million, and .50% of the amount in excess of
$600 million. From time to time, the Adviser may voluntarily elect to subsidize
a portion of the Fund's expenses. The voluntary subsidy may be discontinued at
any time without prior notice. There were no subsidies during the fiscal year
ended November 30, 1994.
 
     Other transactions with affiliates during the year were as follows:

Sales of Fund shares:

  Retail Dealer commissions........................................................     8,526
</TABLE>
 
     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.
These charges included 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. These services provided by the Adviser are
at cost.
 
     Legal fees were for services rendered by O'Melveny & Myers, counsel for the
Fund. Lawrence J. Sheehan, of counsel to that firm, is a trustee of the Fund.
Van Kampen American Capital Shareholder Services, Inc., an affiliate of the
Adviser, serves as the Fund's shareholder service agent. These services are
provided at cost plus a profit.
 
     The Fund was informed that Van Kampen American Capital Distributors, Inc.
(the "Distributor") and Advantage Capital Corporation (the "Retail Dealer"),
both affiliates of the Adviser, received commissions charged on sales of Fund
shares during the year.
 
     Under the terms of the Distribution plans, the Fund pays up to .25% per
annum of its average daily net assets to reimburse the Distributor for expenses
and service fees incurred. Class B and Class C shares pay an additional
distribution fee of up to .75% per annum of their average net assets to
reimburse the Distributor for its distribution expenses. Actual distribution
expenses incurred by the Distributor for Class B and Class C shares may exceed
the amounts reimbursed to the Distributor by the Fund. At November 30, 1994, the
unreimbursed expenses by the Distributor under the Class B and Class C plans
aggregated approximately $1.5 million and $36,000, 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 reimbursements of distribution fees.

"Plan"). The Plan is not funded, and obligations under the Plan will be paid
solely out of the general accounts. Funds for the payment of obligations under
the Plan will not be reserved or set aside by any form of trust or escrow. Each
director covered by the Plan has elected 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 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 a higher distribution services fee 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 an unlimited number of $.01 par value shares of beneficial
interest authorized. Transactions in shares of beneficial interest were as

REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF
AMERICAN CAPITAL TAX-EXEMPT INSURED MUNICIPAL PORTFOLIO
 
     In our opinion, the accompanying statement of assets and liabilities,
including the investment portfolio and the related statement of operations and
of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of American Capital Tax-Exempt Insured
Municipal Portfolio (the "Fund") at November 30, 1994, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended and the selected per share data and
ratios for each of the 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
misstatements. 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 November 30, 1994 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.
