                              TO SHAREHOLDERS OF:
                           VAN KAMPEN FLORIDA INSURED
                              TAX FREE INCOME FUND

                                                             QUESTIONS & ANSWERS

- ---------------------------------------
  We recommend that you read the complete Prospectus/Proxy Statement. For your
  convenience, we have provided a brief overview of the issue to be voted on.
- ---------------------------------------
Q
       WHY IS A SHAREHOLDER MEETING BEING HELD?
A      You are being asked to vote
on a reorganization (the "Reorganization") of Van Kampen Florida Insured Tax
Free Income Fund (the "Target Fund") into Van Kampen Insured Tax Free Income
Fund (the "Acquiring Fund"), a fund that pursues a similar investment objective.
Q
       WHY IS THE REORGANIZATION BEING RECOMMENDED?
A      The purpose of the proposed
Reorganization is to permit the shareholders of the Target Fund to (i) achieve
certain economies of scale from the Acquiring Fund's larger net asset size and
the potentially lower operating expenses (excluding any fee waivers) associated
therewith, (ii) eliminate the duplication of services and expenses that
currently exists as a result of the separate operations of the funds and (iii)
obtain potentially greater portfolio diversity and potentially lower portfolio
transaction costs. In addition, effective July 1, 2003, exemptions from the
Florida intangible personal property tax will increase. The effect of such
increased exemptions will be to reduce the Florida intangible personal property
tax benefit of investing in shares of the Target Fund.
Q
       HOW WILL THE REORGANIZATION AFFECT ME?
A      Assuming shareholders of the
Target Fund approve the Reorganization, the assets and liabilities of the Target
Fund will be combined with those of the Acquiring Fund, and you will become a
shareholder of the Acquiring Fund. You will receive shares of the Acquiring Fund
equal in value at the time of issuance to your shares of the Target Fund. Unlike
the Target Fund, the Acquiring Fund does not, as part of its investment
objective, seek income exempt from Florida intangible personal property taxes.
In evaluating the Reorganization, Target Fund shareholders should consider the
impact of losing the exemption from Florida intangible personal property taxes.
Q
       WILL I HAVE TO PAY ANY SALES LOAD, COMMISSION OR OTHER SIMILAR FEE IN
       CONNECTION WITH THE REORGANIZATION?
A      You will pay no sales loads or
commissions in connection with the Reorganization. The costs associated with the
proposed Reorganization, including the costs associated with the


shareholder meeting, will be shared by Van Kampen Investment Advisory Corp. and
the Acquiring Fund. As more fully discussed in the combined Prospectus/Proxy
Statement, the holding period with respect to any contingent deferred sales
charge applicable to shares of the Acquiring Fund acquired in the Reorganization
will be measured from the earlier of the time (i) the holder purchased such
shares from the Target Fund or (ii) the holder purchased shares of any other Van
Kampen fund and subsequently exchanged them for shares of the Target Fund.
Q
       HOW DO ADVISORY AND OTHER OPERATING FEES PAID BY THE ACQUIRING FUND
       COMPARE TO THOSE PAYABLE BY THE TARGET FUND?
A      Management of the funds
anticipates that, as a result of the Reorganization, shareholders of the Target
Fund would be subject to lower investment advisory fees and lower total
operating expenses as a percentage of net assets. The total operating expenses
of the Target Fund are currently less than those of the Acquiring Fund, but only
because of voluntary fee waivers or reimbursements from the Target Fund's
investment adviser. Absent such voluntary fee waivers or reimbursements, the
total operating expenses of the Target Fund would be significantly higher than
those of the Acquiring Fund. There can be no assurance that such waivers or
reimbursements will continue for the Target Fund if the Reorganization is not
completed.
Q
       WHAT WILL I HAVE TO DO TO OPEN AN ACCOUNT IN THE ACQUIRING FUND? WHAT
       HAPPENS TO MY ACCOUNT IF THE REORGANIZATION IS APPROVED?
A      If the Reorganization is
approved, your interest in shares of the Target Fund automatically will be
converted into shares of the Acquiring Fund, and we will send you written
confirmation that this change has taken place. You will receive the same class
of shares of the Acquiring Fund equal in value to your class of shares of the
Target Fund. Holders of Class A shares of the Target Fund will receive Class A
shares of the Acquiring Fund; holders of Class B shares of the Target Fund will
receive Class B shares of the Acquiring Fund; and holders of Class C shares of
the Target Fund will receive Class C shares of the Acquiring Fund. No
certificates for Acquiring 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 Target Fund, it
is not necessary to return such certificates; however, shareholders may want to
present such certificates to receive certificates of the Acquiring Fund (to
simplify substantiation of and to preserve the tax basis of separate lots of
shares).
Q
       WILL I HAVE TO PAY ANY FEDERAL TAXES AS A RESULT OF THE REORGANIZATION?
A      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. If the
Reorganization so qualifies, in general, a shareholder of the Target Fund will
recognize no gain or loss upon the receipt solely of the shares of the Acquiring
Fund in connection with the Reorganization. Additionally, the Target 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 Acquiring Fund or as a
result of its liquidation.


Q
       WHAT IF I REDEEM OR EXCHANGE MY SHARES OF THE TARGET FUND BEFORE THE
       REORGANIZATION TAKES PLACE?
A      If you choose to redeem or
exchange your shares of the Target Fund before the Reorganization takes place,
the redemption or exchange will be treated as a normal redemption or exchange of
shares and generally will be a taxable transaction.

                           PROSPECTUS/PROXY STATEMENT

                    VAN KAMPEN INSURED TAX FREE INCOME FUND

            RELATING TO THE ACQUISITION OF ASSETS AND LIABILITIES OF

                VAN KAMPEN FLORIDA INSURED TAX FREE INCOME FUND

  This Prospectus/Proxy Statement is being furnished to shareholders of Van
Kampen Florida Insured Tax Free Income Fund (the "Target Fund") and relates to
the special meeting of shareholders of the Target Fund to be held at the offices
of Van Kampen Investments Inc., 1 Parkview Plaza, Oakbrook Terrace, Illinois
60181-5555 on August 28, 2002 at 3:00 p.m. and at any and all adjournments
thereof (the "Special Meeting"). Shareholders of record as of the close of
business on May 29, 2002 are entitled to vote at the Special Meeting or any
adjournment thereof. The purpose of the Special Meeting is to approve or
disapprove the proposed reorganization of the Target Fund (the "Reorganization")
into the Van Kampen Insured Tax Free Income Fund (the "Acquiring Fund"). The
Reorganization would result in shareholders of the Target Fund in effect
exchanging their Class A, B and C Shares of the Target Fund for corresponding
Class A, B and C Shares of the Acquiring Fund. The purpose of the Reorganization
is to permit shareholders of the Target Fund to (i) achieve certain economies of
scale from the Acquiring Fund's larger net asset size and the potentially lower
operating expenses (excluding any fee waivers) associated therewith, (ii)
eliminate the duplication of services and expenses that currently exists as a
result of the separate operations of the funds and (iii) obtain potentially
greater portfolio diversity and potentially lower portfolio transaction costs.


  Each of the Acquiring Fund and the Target Fund is a series of the Van Kampen
Tax Free Trust, an open-end management investment company (the "Tax Free
Trust"). The investment objective of the Acquiring Fund is to provide investors
with a high level of current income exempt from federal income tax, with
liquidity and safety of principal, primarily through investment in a diversified
portfolio of insured municipal securities. The investment objective of the
Target Fund is to provide investors with a high level of current income exempt
from federal income tax and Florida intangible personal property taxes,
consistent with the preservation of capital. The investment objective of the
Target Fund is similar to the investment objective of the Acquiring Fund and the
funds employ similar investment policies and practices in seeking to achieve
their respective investment objectives. There can be no assurance that either
fund will achieve its investment objective. The address, principal executive
office and telephone number of the funds is 1 Parkview Plaza, PO Box 5555,
Oakbrook Terrace, Illinois 60181-5555, (630) 684-6000 or (800) 341-2911. The
enclosed proxy and this Prospectus/Proxy Statement are first being sent to
Target Fund shareholders on or about July 1, 2002.


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

  Shares of the Acquiring Fund have not been approved or disapproved by the
Securities and Exchange Commission (SEC) or any state regulator, and neither the
SEC nor any state regulator has passed upon the accuracy or adequacy of this
Prospectus/Proxy Statement. Any representation to the contrary is a criminal
offense.

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

                          THE PROPOSED REORGANIZATION

A. SUMMARY

  The following is a summary of, and is qualified by reference to, the more
complete information contained in this Prospectus/Proxy Statement and the
information attached hereto or incorporated herein by reference. As discussed
more fully below and elsewhere in this Prospectus/Proxy Statement, the Board of
Trustees of the Target Fund (the "Target Fund Board") believes the proposed
Reorganization (as defined herein) is in the best interests of shareholders of
the Target Fund. As a result of the Reorganization, shareholders of the Target
Fund would acquire an interest in the Acquiring Fund.

  Shareholders should read the entire Prospectus/Proxy Statement carefully
together with (i) the Acquiring Fund Prospectus incorporated herein by reference
and accompanying this Prospectus/Proxy Statement and (ii) the Target Fund
Prospectus incorporated herein by reference. This Prospectus/Proxy Statement
constitutes an offering of Class A, B and C Shares of the Acquiring Fund only.

THE REORGANIZATION

  This Prospectus/Proxy Statement is being furnished to shareholders of the
Target Fund in connection with the proposed combination of the Target Fund with
and into the Acquiring Fund pursuant to the terms and conditions of the
Agreement and Plan of Reorganization between the Tax Free Trust, on behalf of
the Target Fund, and the Tax Free Trust, on behalf of the Acquiring Fund (the
"Agreement"). The Agreement provides that the Target Fund would (i) transfer all
of its assets to the Acquiring Fund in exchange solely for Class A, B and C
Shares of beneficial interest of the Acquiring Fund and the Acquiring Fund's
assumption of the liabilities of the Target Fund, (ii) distribute to each
shareholder of the Target Fund shares of the respective class of shares of the
Acquiring Fund equal in value to the shareholder's existing shares of the Target
Fund and (iii) dissolve pursuant to a plan of liquidation and dissolution
promptly following the Closing (as defined herein) (collectively, the
"Reorganization").

  The Target Fund Board has determined that the Reorganization is in the best
interests of shareholders of each class of shares of the Target 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 Acquiring Fund (the
"Acquiring Fund Board") has determined that the Reorganization is in the best
interests of the Acquiring Fund and that the interests of each class of shares
of existing shareholders of the Acquiring Fund will not be diluted as a result
of the Reorganization.

  The Target Fund Board is asking shareholders of the Target Fund to approve the
Reorganization at the Special Meeting to be held on August 28, 2002. If
shareholders of the Target Fund approve the Reorganization, it is expected that
the Closing

                                        4


will be after the close of business on or about September 6, 2002, but it may be
at a different time as described herein.

  THE TARGET FUND 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 OF THE TARGET FUND. SEE "VOTING INFORMATION
AND REQUIREMENTS" BELOW.

REASONS FOR THE PROPOSED REORGANIZATION

  The Target Fund Board believes that the proposed Reorganization would be in
the best interests of the shareholders of the Target Fund because it would
permit the shareholders of the Target Fund to (i) achieve certain economies of
scale from the Acquiring Fund's larger net asset size and the potentially lower
operating expenses (excluding fee waivers) associated therewith, (ii) eliminate
the duplication of services and expenses that currently exists as a result of
the separate operations of the funds, and (iii) obtain potentially greater
portfolio diversity and potentially lower portfolio transaction costs.

  In determining whether to recommend approval of the Reorganization to
shareholders of the Target Fund, the Target Fund Board considered a number of
factors, including, but not limited to: (i) the expenses and advisory fees
applicable to the Target Fund and the Acquiring Fund before the Reorganization
and the estimated expense ratios of the Acquiring Fund after the Reorganization;
(ii) the comparative investment performance of the Target Fund and the Acquiring
Fund; (iii) the terms and conditions of the Agreement and whether the
Reorganization would result in dilution of Target Fund shareholder interests;
(iv) the advantages of eliminating duplication of effort in marketing funds
having similar investment objectives in addition to the economies of scale
potentially realized through the combination of the two funds; (v) the
compatibility of the funds' investment objectives; (vi) the compatibility of the
funds' service features available to shareholders, including the retention of
applicable holding periods and exchange privileges; (vii) the costs estimated to
be incurred by the Acquiring Fund and Van Kampen Investment Advisory Corp. (the
"Adviser"), investment adviser to both the Target Fund and Acquiring Fund, as a
result of the Reorganization; (ix) the future growth prospects of the Target
Fund; and (ix) the anticipated tax consequences of the Reorganization, including
differences in state tax treatment of the Target Fund and the Acquiring Fund. In
this regard, the Target Fund Board reviewed information provided by the Adviser
and Van Kampen Investments Inc., the parent corporation of the Adviser ("Van
Kampen"), relating to the anticipated impact to the shareholders of the Target
Fund as a result of the Reorganization. The Target Fund Board considered the
probability that the elimination of duplicative operations and the increase in
asset levels of the combined fund after the

                                        5


Reorganization would result in the following potential benefits for shareholders
of the Target Fund, although there can, of course, be no assurances in this
regard:


  (1) Achievement of Economies of Scale and Reduced Per Share Expenses.
      Combining the net assets of the Target Fund with the assets of the
      Acquiring Fund should lead to reduced total operating expenses for
      shareholders of the Target Fund, on a per share basis, by allowing fixed
      and relatively fixed costs, such as accounting, legal and printing
      expenses, to be spread over a larger asset base. The total operating
      expenses of the Target Fund are currently less than those of the Acquiring
      Fund but only because of such voluntary fee and expense waivers or
      reimbursements from the Adviser. Any reductions in expenses on a per share
      basis should, in turn, have a favorable effect on the relative total
      return to shareholders of the Target Fund. There can be no assurance that
      such waivers or reimbursements will continue for the Target Fund if the
      Reorganization is not completed. Management anticipates that the
      reorganization would have no or only a de minimis effect upon current
      shareholders of the Acquiring Fund.


  (2) Elimination of Separate Operations.  Consolidating the Target Fund and the
      Acquiring Fund should eliminate the duplication of services and expenses
      that currently exists as a result of their separate operations.
      Consolidating the separate operations of the Target Fund with those of the
      Acquiring Fund should promote more efficient operations on a more cost-
      effective basis.

  (3) Benefits to the Portfolio Management Process.  The larger net asset size
      of the Acquiring Fund generally permits it to purchase individual
      portfolio investments that are larger than those purchased by the Target
      Fund. These larger investments may result in reduced transaction costs or
      more favorable pricing and provide the opportunity for greater portfolio
      diversity.

  In addition, effective July 1, 2003, (i) the maximum amounts of taxable
intangible personal property exempt from the Florida intangible personal
property tax increase from $20,000 to $250,000 for single individuals and from
$40,000 to $500,000 for married individuals filing jointly, and (ii) a $250,000
exemption from Florida intangible personal property tax for trusts and business
entities will become available. These exemptions will be in addition to the
$60,000 Florida intangible personal property tax credit provided under current
Florida tax law. The effect of such increased exemptions from the Florida
intangible personal property tax will be to further reduce the Florida
intangible personal property tax benefit of investing in shares of the Target
Fund. Public discussion continues regarding the possible repeal of the Florida
intangible personal property tax or, alternatively, a further reduction in such
tax. The increase in exemptions was slated to become effective January 1,

                                        6


2002; however, national and state economic conditions prompted the Florida
Legislature to delay the effective date during a Special Legislative session in
the Fall of 2001.

  Based upon these and other factors, the Target Fund Board unanimously
determined that the Reorganization is in the best interests of the shareholders
of the Target Fund.

COMPARISON OF THE ACQUIRING FUND AND THE TARGET FUND

  INVESTMENT OBJECTIVES AND POLICIES. The Target Fund and the Acquiring Fund
(each a "Fund" and together, the "Funds") have similar investment objectives.
The investment objective of the Target Fund is to provide investors with a high
level of current income exempt from federal income tax and Florida intangible
personal property taxes, consistent with preservation of capital. The investment
objective of the Acquiring Fund is to provide investors with a high level of
current income exempt from federal income tax, with liquidity and safety of
principal, primarily through investment in a diversified portfolio of insured
municipal securities. The most significant difference between the Funds'
investment objectives is that the Target Fund seeks to provide a high level of
current income exempt from both Florida intangible personal property taxes and
federal income tax, while the Acquiring Fund seeks to provide income that is
exempt from federal income tax only.

  The Target Fund seeks to achieve its investment objective by investing
primarily in a portfolio of Florida municipal securities that are insured at the
time of investment as to timely payment of principal and interest by an entity
whose claims-paying ability is rated AAA by Standard and Poor's ("S&P") or Aaa
by Moody's Investors Service, Inc. ("Moody's") or an equivalent rating by
another nationally recognized statistical rating organization ("NRSRO").

  The Acquiring Fund seeks to achieve its investment objective by investing
substantially all of the Fund's assets in a portfolio of municipal securities
that are insured at the time of purchase as to timely payment of principal and
interest by an entity whose claims-paying ability is rated AAA by S&P or Aaa by
Moody's or an equivalent rating by another NRSRO. Municipal securities are
obligations issued by or on behalf of states, territories or possessions of the
United States, the District of Columbia and their political subdivisions,
agencies and instrumentalities, the interest on which, in the opinion of bond
counsel or other counsel to the issuers of such securities, is, at the time of
issuance, exempt from federal income tax. Florida municipal securities are
municipal securities which, in the opinion of bond counsel or other counsel of
the issuers of such securities, are, at the time of issuance, exempt from
Florida intangible personal property taxes.

  Each Fund's investment adviser actively manages the Fund's portfolio and
adjusts the average maturity of portfolio investments based upon its
expectations
                                        7


about the direction of interest rates and other economic factors. In selecting
securities for investment, each Fund's investment adviser uses its research
capabilities to identify and monitor attractive investment opportunities and to
seek to protect the Fund's portfolio from early payment by issuers of such
securities. In conducting its research and analysis, each Fund's investment
adviser considers a number of factors, including general market and economic
conditions and credit, interest rate and prepayment risks. Portfolio securities
are typically sold when the assessments of the Fund's investment adviser of any
of these factors materially change. Although each Fund invests in insured
municipal securities, insurance does not protect a Fund from market fluctuations
in the value of an insured security, but only guarantees timely payment of
principal and interest of such investments. Under normal market conditions, each
Fund may invest up to 20% of its net assets in municipal securities that are
subject to the federal alternative minimum tax. From time to time, each Fund
temporarily may invest up to 10% of its total assets in tax-exempt money market
funds, which are not insured.

  Each Fund may, but is not required to, use various investment strategic
transactions described below to earn income, facilitate portfolio management and
mitigate risks. Each Fund may purchase and sell derivative instruments such as
exchange-listed and over-the-counter put and call options on securities,
financial futures contracts, fixed-income and other interest rate indices and
other financial instruments, purchase and sell financial futures contracts and
options on futures contracts and enter into various interest rate transactions
such as swaps, caps, floors or collars.

  Each Fund may invest in zero coupon securities, which are debt securities that
do not entitle the holder to periodic payment of interest prior to maturity or a
specified date when the securities begin paying current interest. Each Fund may
purchase and sell securities on a "when-issued" and "delayed delivery" basis
whereby the Fund buys or sells a security with payment and delivery taking place
in the future. No specific limitation exists as to the percentage of either
Fund's assets which may be used to acquire securities on a "when-issued" and
"delayed delivery" basis. Each Fund may invest up to 15% of the Fund's net
assets in illiquid securities and certain restricted securities. Each Fund may
borrow amounts up to 5% of its total assets to pay for redemptions when
liquidation of portfolio securities is considered disadvantageous or
inconvenient and may pledge up to 10% of its total assets to secure such
borrowings.

  Diversification.  The Target Fund is classified as non-diversified within the
meaning of the 1940 Act, which means that the Target Fund is not limited by the
1940 Act in the proportion of its total assets that it may invest in securities
of a single issuer. However, the Target Fund's investments are limited so as to
qualify the Fund for the special tax treatment afforded regulated investment
companies under the federal tax laws. To qualify, among other requirements, each
Fund limits

                                        8


its investments so that, at the close of each quarter of the taxable year, (i)
not more than 25% of the market value of the Fund's total assets will be
invested in the securities (other than U.S. government securities) of a single
issuer, and (ii) with respect to 50% of the market value of its total assets,
not more than 5% of the market value of its total assets will be invested in the
securities (other than U.S. Government securities) of a single issuer. The
Acquiring Fund is registered as a "diversified" fund within the meaning of the
1940 Act, which means that the Acquiring Fund must satisfy the foregoing 5%
requirement with respect to 75% of its total assets. Moreover, the Acquiring
Fund has a fundamental investment restriction which provides that the Fund may
not purchase securities of an issuer (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 its total assets (taken at
current value) would then be invested in securities of a single issuer or if as
a result the Acquiring Fund would hold more than 10% of the outstanding voting
securities of any single issuer. To the extent that a Fund assumes large
positions in the securities of a small number of issuers, the Fund's performance
may fluctuate to a greater extent than that of a diversified fund as a result of
changes in the financial condition or in the market's assessment of the issuers.

  INVESTMENT ADVISER. Van Kampen Investment Advisory Corp. serves as investment
adviser to each of the Funds. The Adviser is a wholly owned subsidiary of Van
Kampen. Van Kampen is a diversified asset management company that administers
more than three million retail investor accounts, has extensive capabilities for
managing institutional portfolios and has more than $74 billion under management
or supervision as of March 31, 2002. Van Kampen Investments has more than 50
open-end funds, more than 30 closed-end funds and more than 2,700 unit
investment trusts that are distributed by authorized dealers nationwide. Van
Kampen Funds Inc., the distributor of each of the Funds (the "Distributor"), is
also a wholly owned subsidiary of Van Kampen. Van Kampen is an indirect wholly
owned subsidiary of Morgan Stanley Dean Witter & Co. The Adviser's principal
office is located at 1 Parkview Plaza, Oakbrook Terrace, Illinois 60181-5555.

  The Target Fund is managed by the Adviser's Municipal team. The team is made
up of established investment professionals. Current members of the team includes
Dennis S. Pietrzak, an Executive Director of the Adviser, John R. Reynoldson, an
Executive Director of the Adviser and Thomas M. Byron, a Vice President of the
Adviser. The composition of the team may change without notice from time to
time.

  The Acquiring Fund is managed by the Adviser's Investment Grade Municipal
team. The team is made up of established investment professionals. Current
members of the team include James F. Willison, a Managing Director of the
Adviser, Joseph R. Arcieri, an Executive Director of the Adviser and Joseph A.

without notice from time to time.

  ADVISORY AND OTHER FEES. The contractual advisory fees of the Acquiring Fund
and the Target Fund are set forth below. Each of the Funds is obligated to pay
the Adviser a monthly fee based on its average daily net assets.

  The Acquiring Fund's contractual advisory fee is as follows:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS                                  % PER ANNUM
- ------------------------                                  -----------
                                                       
First $500 million......................................    0.525%
Next $500 million.......................................    0.500%
Next $500 million.......................................    0.475%
Over $1.5 billion.......................................    0.450%
</Table>

  Applying this fee schedule, the Acquiring Fund paid the Adviser an advisory
fee at the effective rate of 0.506% of the Acquiring Fund's average net assets
for the Acquiring Fund's six months ended March 31, 2002.

  The Target Fund's contractual advisory fee is as follows:

<Table>
<Caption>
AVERAGE DAILY NET ASSETS                                  % PER ANNUM
- ------------------------                                  -----------
                                                       
First $500 million......................................    0.500%
Over $500 million.......................................    0.450%
</Table>

  During the Target Fund's six months ended March 31, 2002, the contractual
advisory fees were 0.50% of the Target Fund's net assets but the Target Fund
paid the Adviser at an effective rate of 0% due to a voluntary fee waiver by the
Adviser. Such fee waivers may be discontinued by the Adviser at any time.

  The Adviser retains the right from time to time to waive all or a portion of
its management fee or to reimburse the respective Fund for all or a portion of
its other expenses. For a complete description of each Fund's advisory services,
see the section of the Fund's Prospectus entitled "Investment Advisory Services"
and the section of the Acquiring Fund Statement of Additional Information
entitled "Investment Advisory Agreement".

  The total operating expenses of the Acquiring Fund for the six months March
31, 2002 (on an annualized basis) were 0.87% of the average daily net assets for
Class A Shares and 1.63% of the average daily net assets for Class B Shares and
Class C Shares. No fee waivers or expense reimbursements were in effect with
respect to the Acquiring Fund during such period.


  The total operating expenses (before fee waiver) of the Target Fund for the
six months March 31, 2002 were 1.15% of average daily net assets for Class A
Shares, 1.90% of the average daily net assets for Class B Shares and 1.89% of
average daily net assets for Class C Shares. The total operating expenses (net
of fee waiver) of the Target Fund were 0.63% of average daily net assets for
Class A Shares, 1.38% of

                                        10



the average daily net assets for Class B Shares and 1.37% of the average daily
net assets for Class C Shares, for that same period.


  The total operating expenses of the Target Fund are currently less than those
of the Acquiring Fund, but only because of voluntary fee waivers or
reimbursements from the fund's investment adviser. Absent such voluntary fee
waivers or reimbursements, the total operating expenses of the Target Fund would
be significantly higher than those of the Acquiring Fund. There can be no
assurance that such waivers or reimbursements will continue for the Target Fund
if the Reorganization is not completed.

  The Acquiring Fund and the Target Fund have adopted substantially identical
distribution plans (the "Distribution Plans") pursuant to Rule 12b-1 under the
1940 Act and have adopted substantially identical service plans (the "Service
Plans"). Both the Acquiring Fund and the Target Fund can pay up to 0.25% of
their respective average daily net assets attributable to Class A Shares for
distribution-related expenses and for the provision of ongoing services to
shareholders. Both the Acquiring Fund and the Target Fund can pay up to 0.75% of
their respective average daily net assets attributable to Class B Shares and
Class C Shares for reimbursement of certain distribution-related expenses. In
addition, both the Acquiring Fund and the Target Fund can pay up to 0.25% of the
respective average daily net assets attributable to Class B Shares and Class C
Shares for the provision of ongoing services to shareholders. The distributor of
both the Acquiring Fund's shares and the Target Fund's shares is Van Kampen
Funds Inc. (the "Distributor"), a subsidiary of Van Kampen. For a complete
description of these arrangements with respect to each Fund, see the section of
the Fund's Prospectus entitled "Purchase of Shares" and the section of the
Statement of Additional Information entitled "Distribution and Service".

Notes to Expense Comparison Table

(1) Reduced on purchases of $100,000 and over. Class A Shares of the Acquiring
    Fund received pursuant to the Reorganization will not be subject to a sales
    charge upon purchase.

(2) Investments of $1,000,000 or more are not subject to any sales charge at the
    time of purchase but a deferred sales charge of 1.00% may be imposed on
    certain redemptions made within one year of purchase.

(3) Class B Shares of each 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 after a six year period as
    follows: Year 1 -- 4.00%; Year 2 -- 3.75%; Year 3 -- 3.50%; Year 4 -- 2.50%;
    Year 5 -- 1.50%; Year 6 -- 1.00%; and after Year 6 -- 0.00%.

(4) Class C Shares of each 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 Class C Shares redeemed during the first year
    after purchase, which charge is reduced to zero thereafter.


(5) The Target Fund's investment adviser is currently waiving or reimbursing a
    portion of the Target Fund's management fees and other expenses such that
    the actual total annual fund operating expenses were 0.63% for Class A
    Shares, 1.38% for Class B Shares and 1.37% for Class C Shares for the six
    month period ended March 31, 2002. The fee waivers or expense reimbursements
    can be terminated at any time.


(6) Class A Shares are subject to a combined annual distribution and service fee
    of up to 0.25% of the average daily net assets attributable to such class of
    shares. Class B Shares and Class C Shares are each subject to a combined
    annual distribution and service fee of up to 1.00% of the average daily net
    assets attributable to such class of shares.

(7) Because distribution and/or service (12b-1) fees are paid out of a Fund's
    assets on an ongoing basis, over time these fees will increase the cost of
    your investment and may cost you more than paying other types of sales
    charges.

EXAMPLE. The following examples are intended to help you compare the costs of
investing in the Acquiring Fund, both before and pro forma after the
Reorganization, with the costs of investing in the Target Fund. The examples
assume that you invest $10,000 in each Fund for the time periods indicated and
then redeem all of your shares at the end of those periods. The examples also
assume that your investments each have a 5% return each year and that each
Fund's operating expenses remain the same each year (except for the ten-year
amounts for Class B Shares which reflect the conversion of Class B Shares to
Class A Shares eight years after the end of the calendar month in which the
shares were purchased). Although your actual returns and costs may be higher or
lower, based on these assumptions your costs would be:

  DISTRIBUTION, PURCHASE, VALUATION, REDEMPTION AND EXCHANGE OF SHARES. Both the
Acquiring Fund and the Target Fund offer three classes of shares. The Class A
Shares of each Fund are subject to an initial sales charge of up to 4.75%. The
initial sales charge applicable to Class A Shares of the Acquiring Fund will be
waived for Class A Shares acquired in the Reorganization. Any subsequent
purchases of Class A Shares of the Acquiring Fund after the Reorganization will
be subject to an initial sales charge of up to 4.75%, excluding Class A Shares
purchased through the dividend reinvestment plan. Purchases of Class A Shares of
each 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. No contingent
deferred sales charge will be imposed on Class A Shares of the Target Fund in
connection with the Reorganization.

  The Class B Shares of each 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 after a six year period. The deferred sales charge schedules for the
Funds are identical.

  The Class C Shares of each Fund do not incur a sales charge when purchased,
but generally are subject to a contingent deferred sales charge of 1.00% if
redeemed within the first year after purchase.

  No contingent deferred sales charge will be imposed on Class B Shares or Class
C Shares of the Target Fund in connection with the Reorganization. The holding
period and conversion schedule for Class B Shares or Class C Shares of the
Acquiring Fund received in connection with the Reorganization will be measured
from the earlier time (i) the holder purchased such shares from the Target Fund
or (ii) the holder purchased such shares from any other fund advised by the
Adviser and distributed by the Distributor and subsequently exchanged them for
shares of the Target Fund.

  Shares of each Fund may be purchased by check, by electronic transfer, by bank
wire and by exchange from certain other funds advised by the Adviser or Van
Kampen Asset Management Inc. and distributed by the Distributor. For a complete
description regarding purchase of shares and exchange of shares of the Acquiring
Fund, see the sections of the Acquiring Fund Prospectus entitled "Purchase of
Shares" and "Shareholder Services--Exchange Privilege." For a complete
description regarding purchase of shares and exchange of shares of the Target
Fund, see the sections of the Target Fund Prospectus entitled "Purchase of
Shares" and "Shareholder Services--Exchange Privilege".

  Shares of each Fund properly presented for redemption may be redeemed or
exchanged at the next determined net asset value per share (subject to any
applicable contingent deferred sales charge). Shares of each Fund may be
redeemed or exchanged by mail or by special redemption privileges (telephone

                                        14


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, usually a period of up to 15 days.

  No further purchases of the shares of the Target Fund may be made after the
date on which the shareholders of the Target Fund approve the Reorganization,
and the stock transfer books of the Target 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 Target Fund. Redemption requests or transfer
instructions received by the Target Fund after that date will be treated by the
Target Fund as requests for the redemption or instructions for the transfer of
the shares of the Acquiring Fund credited to the accounts of the shareholders of
the Target Fund. Redemption requests or transfer instructions received by the
Target Fund after the close of business on the day prior to the date of Closing
will be forwarded to the Acquiring Fund. For a complete description of the
redemption arrangements for each Fund, see the section of each Fund's Prospectus
entitled "Redemption of Shares."

Acquiring Fund and the Target Fund as of March 31, 2002, and the pro forma
capitalization of the combined fund as if the Reorganization had occurred on

(1) The pro forma net assets and net asset value per share reflect the payment
    of 23% of the reorganization expenses of approximately $46,000 by the
    Acquiring Fund (allocated among the classes of approximately $43,000, $2,000
    and $1,000 for Class A, Class B and Class C Shares, respectively). The
    remaining portion of the reorganization expenses will be paid by the
    Adviser.


(2) The pro forma shares outstanding reflect the issuance by the Acquiring Fund
    of approximately 2,245,000 Class A Shares, 1,884,000 Class B Shares and
    306,000 Class C Shares reflecting the exchange of the assets and liabilities
    of the Target Fund for newly issued shares of the Acquiring Fund at the pro
    forma net asset value per share.

  PERFORMANCE INFORMATION. As a basis for evaluating each Fund's performance and
risks, the table below shows how each Fund's performance compares with the
Lehman Brothers Municipal Bond Index*, a broad-based market index that the
Adviser believes is an appropriate benchmark for the Funds. Each Fund's
performance figures listed below include the maximum sales charges paid by
investors. The index's performance figures do not include any commissions, sales
charges or taxes that would be paid by investors purchasing the securities
represented by the index. An investment cannot be made directly in the index.
Average annual total returns

                                        16


are shown for the periods ended December 31, 2001 (the most recently completed
calendar year prior to the date of this Prospectus/Proxy Statement). Remember
that past performance of the Fund is not indicative of its future performance.

  In addition to before tax returns for each class of shares, the table also
shows after tax returns for the Fund's Class A Shares in two ways: (i) after
taxes on distributions and (ii) after taxes on distributions and sale of Fund
shares. The after tax returns for the Fund's Class B Shares and Class C Shares
will vary from the Class A Shares' returns. After tax returns are calculated
using the historical highest individual federal marginal income tax rates during
the periods shown and do not reflect the impact of state and local taxes. Actual
after tax returns depend on an investor's tax situation and may differ from
those shown, and after tax returns are not relevant to investors who hold their
Fund shares through tax-deferred arrangements, such as 401(k) plans or
individual retirement accounts. An after tax return may be higher than the
before tax return due to an assumed benefit from any capital loss that would
have been realized had Fund shares been sold at the end of the relevant period.

  OTHER SERVICE PROVIDERS. The transfer agent for each Fund is Van Kampen
Investor Services Inc., a wholly owned subsidiary of Van Kampen. The custodian
for each Fund is State Street Bank and Trust Company. The financial statements
of each Fund contained in the Fund's annual report to shareholders for the
fiscal year ended September 30, 2001, have been audited by Ernst & Young LLP
("Ernst & Young"), 233 South Wacker Drive, Chicago, Illinois 60606, independent
auditors. These financial statements are incorporated by reference into this
Prospectus/Proxy Statement. KPMG LLP, located at 303 East Wacker Drive, Chicago,
Illinois 60601 ("KPMG"), ceased being the Funds' independent auditors effective
April 14, 2000. The cessation of the client-auditor relationship between the
Funds and KPMG was based on a possible business relationship by KPMG with an
affiliate of the Adviser.

                                        18


The change in independent auditors was approved by each Fund's audit committee
and each Fund's Board of Trustees, including Trustees who are not "interested
persons" of such Fund (as defined in the 1940 Act). Unaudited pro forma
financial statements reflecting the Acquiring Fund -- Pro Forma after the
proposed Reorganization are contained in the Statement of Additional Information
dated June 24, 2002, relating to this Prospectus/Proxy Statement. A copy of
either Fund's annual report may be obtained by writing to the Fund or by calling
1-800-341-2929.

B. RISK FACTORS

  The investment objectives and investment policies and practices of the Funds
are similar. The most significant difference between the Funds' investment
objectives is that the Target Fund seeks to provide a high level of current
income exempt from both Florida intangible personal property taxes and federal
income tax, while the Acquiring Fund seeks to provide a high level of current
income that is exempt from federal income tax only. Accordingly, the Target Fund
invests primarily in insured Florida municipal securities, whereas the Acquiring
Fund invests substantially all of its assets in insured municipal securities of
states, territories or possessions of the United States, the District of
Columbia and their political subdivisions, agencies and instrumentalities. Each
Fund may invest up to 20% of its net assets in municipal securities that are
subject to the federal alternative minimum tax and may temporarily invest up to
10% of its total assets in tax-exempt money market funds, which are not insured.
Each Fund may also use certain derivative instruments for various portfolio
management purposes. To the extent that the investment objectives and investment
policies and practices of the Acquiring Fund and the Target Fund are similar,
the risks associated with an investment in the Funds are similar.

  The Acquiring Fund and the Target Fund have some dissimilar investment
policies. To the extent that the investment policies of the Funds differ, the
risks associated with an investment in the Acquiring Fund are different from the
risks associated with an investment in the Target Fund. An investment in the
Acquiring Fund may not be appropriate for all Target Fund shareholders. For a
complete description of the risks of an investment in each Fund, see the
sections in each Fund's Prospectus entitled "Risk/Return Summary" and
"Investment Objectives, Policies, and Risks."

  The investment policies of the Funds differ in that the Target Fund invests
primarily in insured Florida municipal securities, whereas the Acquiring Fund
invests in insured municipal securities of various of states, territories or
possessions of the United States, the District of Columbia and their political
subdivisions, agencies and instrumentalities. Because the Acquiring Fund does
not invest primarily in Florida municipal securities, an investment in the
Acquiring Fund will not be exempt from Florida intangible personal property
taxes. Since the Acquiring

                                        19


Fund does not have a policy of investing primarily in Florida municipal
securities, it is less likely to be affected by adverse political, economic or
regulatory developments affecting issuers of Florida municipal securities. It is
possible, however, that the broader municipal securities market could
underperform relative to Florida municipal securities.

  The Target Fund is classified as non-diversified within the meaning of the
1940 Act, whereas the Acquiring Fund is registered as a "diversified" fund under
the 1940 Act. Moreover, the Acquiring Fund has a fundamental investment
restriction which provides that the Fund may not purchase securities of an
issuer (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 its total assets (taken at current value) would then be invested in
securities of a single issuer or if as a result the Acquiring Fund would hold
more than 10% of the outstanding voting securities of a single issuer. To the
extent that the Target Fund assumes large positions in the securities of a small
number of issuers, the Target Fund's performance may fluctuate to a greater
extent than that of a diversified fund as a result of changes in the financial
condition or in the market's assessment of the issuers.

C. 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 attached as
Appendix A to the Reorganization SAI, a copy of which may be obtained without
charge by calling the Acquiring Fund or the Target Fund at (800) 341-2911 and
asking for the "Reorganization SAI".


TERMS OF THE AGREEMENT

  Pursuant to the Agreement, the Acquiring Fund will acquire all of the assets
and the liabilities of the Target Fund on the date of the Closing in
consideration for Class A, B and C Shares of the Acquiring Fund.

  Subject to the Target Fund's shareholders approving 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
Acquiring Fund and the Target Fund may mutually agree.

  On the date of Closing, the Target Fund will transfer to the Acquiring Fund
all of its assets and liabilities. The Acquiring Fund will in turn transfer to
the Target Fund a number of its Class A, B and C Shares equal in value to the
value of the net assets of the Target Fund transferred to the Acquiring Fund as
of the date of Closing, as determined in accordance with the valuation method
described in the Acquiring

                                        20


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 Target Fund will 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 Target Fund expects to distribute the Class A, B and C Shares of the
Acquiring Fund to the shareholders of the Target Fund promptly after the Closing
and then dissolve pursuant to a plan of dissolution adopted by the Board. The
Target Fund will be deregistered as an investment company under the 1940 Act.

  The Acquiring Fund and the Target Fund 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 Target 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 Acquiring Fund of which this Prospectus/Proxy Statement forms a part
        and the absence of any stop orders under the Securities Act of 1933, as
        amended, 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
Target Fund, provided that no such amendment after such approval shall be made
if it would have a material adverse affect on the interests of Target Fund
shareholders. The Agreement also may 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 Target Fund Board recommends that you vote to approve the Reorganization,
as it believes the Reorganization is in the best interests of the Target Fund's

                                        21


shareholders (as described more fully in "THE PROPOSED REORGANIZATION--Reasons
for the Proposed Reorganization") and that the interests of the Target 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 Acquiring Fund
being offered hereby are represented by transferable Class A, B and C Shares,
par value $0.01 per share.

  VOTING RIGHTS OF SHAREHOLDERS. Holders of shares of the Acquiring Fund are
entitled to one vote per share on matters as to which they are entitled to vote.

  The Acquiring Fund is an open-end management investment company registered
with the SEC under the 1940 Act. Therefore, in addition to the specific voting
rights described above, shareholders of the Acquiring Fund are entitled, under
the 1940 Act, to vote with respect to certain other matters, including changes
in fundamental investment policies and restrictions, the approval of advisory
contracts, distribution contracts and certain distribution-related plans, and
the ratification of the selection of independent accountants.

CONTINUATION OF SHAREHOLDER ACCOUNTS AND PLANS; SHARE CERTIFICATES

  If the Reorganization is approved, the Acquiring Fund will establish an
account for each Target Fund shareholder containing the appropriate number of
shares of the Acquiring Fund. The shareholder services and shareholder programs
of the Acquiring Fund and the Target Fund are substantially identical.
Shareholders of the Target Fund who are accumulating Target Fund shares under
the dividend reinvestment plan, or who are receiving payment under the
systematic withdrawal plan with respect to Target Fund shares, will retain the
same rights and privileges after the Reorganization in connection with the
Acquiring Fund Class A, B or C Shares received in the Reorganization through
substantially identical plans maintained by the Acquiring Fund. Van Kampen Trust
Company will continue to serve as custodian for the assets of Target Fund
shareholders held in IRA accounts after the Reorganization. Such IRA investors
will be sent appropriate documentation to confirm Van Kampen Trust Company's
custodianship.

  It will not be necessary for shareholders of the Target Fund to whom
certificates have been issued to surrender their certificates. Upon dissolution
of the Target Fund, such certificates will become null and void. However, Target
Fund shareholders holding such certificates may want to present such
certificates to receive certificates of the Acquiring Fund (to simplify
substantiation of and to preserve the tax basis of separate lots of shares).

                                        22



MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE REORGANIZATION



  The following is a general summary of the material anticipated U.S. federal
income tax consequences of the Reorganization. The discussion is based upon the
Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations,
court decisions, published positions of the Internal Revenue Service ("IRS") and
other applicable authorities, all as in effect on the date hereof and all of
which are subject to change or differing interpretations (possibly with
retroactive effect). The discussion is limited to U.S. persons who hold shares
of the Target Fund as capital assets for federal income tax purposes. This
summary does not address all of the federal income tax consequences that may be
relevant to a particular shareholder or to shareholders who may be subject to
special treatment under federal income tax laws. No ruling has been or will be
obtained from the IRS regarding any matter relating to the Reorganization. No
assurance can be given that the IRS would not assert a position contrary to any
of the tax aspects described below. Shareholders must consult their own tax
advisers as to the federal income tax consequences of the Reorganization, as
well as the effects of state, local and non-U.S. tax laws.



  It is a condition to closing the Reorganization that each of the Target Fund
and the Acquiring Fund receives an opinion from Skadden, Arps, Slate, Meagher &
Flom (Illinois), special counsel to each Fund ("Skadden Arps"), dated as of the
Closing date, regarding the characterization of the Reorganization as a
"reorganization" within the meaning of Section 368(a) of the Code. As such a
reorganization, the federal income tax consequences of the Reorganization can be
summarized as follows:



    -  No gain or loss will be recognized by the Target Fund or the Acquiring
       Fund upon the transfer of the assets of the Target Fund to the Acquiring
       Fund in exchange solely for the Class A, B or C Shares of the Acquiring
       Fund and the assumption by the Acquiring Fund of the liabilities of the
       Target Fund and the subsequent liquidation of the Target Fund.



    -  No gain or loss will be recognized by a shareholder of the Target Fund
       who exchanges all of his, her or its Class A, B or C Shares of the Target
       Fund solely for, respectively, the Class A, B or C Shares of the
       Acquiring Fund pursuant to the Reorganization.



    -  The aggregate tax basis of the Class A, B or C Shares of the Acquiring
       Fund received by a shareholder of the Target Fund pursuant to the
       Reorganization will be the same as the aggregate tax basis of the Class
       A, B or C Shares of the Target Fund surrendered in exchange therefor.



    -  The holding period of the Class A, B or C Shares of the Acquiring Fund
       received by a shareholder of the Target Fund pursuant to the
       Reorganization will include the holding period of the Class A, B or C
       Shares of the Target Fund surrendered in exchange therefor.

                                        23


    -  The Acquiring Fund's tax basis in the Target Fund's assets received by
       the Acquiring Fund pursuant to the Reorganization will, in each instance,
       equal the tax basis of such assets in the hands of the Target Fund
       immediately prior to the Reorganization, and the Acquiring Fund's holding
       period of such assets will, in each instance, include the period during
       which the assets were held by the Target Fund.

  The opinion of Skadden Arps will be based on federal income tax law in effect
on the Closing date. In rendering its opinion, Skadden Arps will also rely upon
certain representations of the management of the Acquiring Fund and the Target
Fund and assume, among other things, that the Reorganization will be consummated
in accordance with the operative documents. An opinion of counsel is not binding
on the IRS or any court.

  The Acquiring Fund intends to continue 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 Target Fund and its shareholders.

EXPENSES

  The expenses of the Reorganization generally will be shared 23% by the
Acquiring Fund and 77% by the Adviser in the event the Reorganization is
completed, in approximate proportion to the benefits received by the Acquiring
Fund and the Adviser in connection with the Reorganization. Management believes
that shareholders of the Target Fund and the Acquiring Fund will benefit from
the Reorganization due to anticipated decreases in operating expenses of each
Fund and the Adviser will benefit from operational efficiencies of the combined
Fund. See the "Fee and Expense Comparison Table" above. Management of the Target
Fund and the Acquiring Fund estimates total Reorganization costs of
approximately $201,000. In the event the Reorganization is not completed, the
Adviser will bear the costs associated with the Reorganization. The Acquiring
Fund Board and the Target Fund Board have reviewed and approved the foregoing
arrangements with respect to expenses and other charges relating to the
Reorganization.

  As noted above, shareholders of the Target Fund may redeem their shares or
exchange their shares for shares of certain other funds distributed by the
Distributor at any time prior to the closing of the Reorganization. See
"Distribution, Purchase, Valuation, Redemption and Exchange of Shares" above.
Redemptions and exchanges of shares generally are taxable transactions, unless
your account is not subject to taxation, such as an individual retirement
account or other tax-qualified retirement plan. Shareholders should consult with
their own tax advisers regarding potential transactions.

                                        24


LEGAL MATTERS

  Certain legal matters concerning the federal income tax consequences of the
Reorganization and issuance of Class A, B and C Shares of the Acquiring Fund
will be passed on by Skadden Arps, 333 West Wacker Drive, Chicago, Illinois
60606, which serves as counsel to the Acquiring Fund and the Target Fund. Wayne
W. Whalen, a partner of Skadden Arps, is a Trustee of each Fund.

D. RECOMMENDATION OF THE BOARD

  The Target Fund Board has unanimously approved the Agreement and has
determined that participation in the Reorganization is in the best interests of
shareholders of each class of shares of the Target Fund. THE TARGET FUND BOARD
RECOMMENDS VOTING "FOR" THE PROPOSED REORGANIZATION.

B. SHAREHOLDER PROPOSALS

  As a general matter, the Acquiring Fund does not intend to hold future regular
annual or special meetings of its shareholders unless required by the 1940 Act.
In the event the Reorganization is not consummated, the Target Fund does not
intend to hold future regular annual or special meetings of its shareholders
unless required by the 1940 Act. Any shareholder who wishes to submit proposals
for consideration at a meeting of shareholders of the Acquiring Fund or the
Target Fund should send such proposal to the respective Fund at 1 Parkview
Plaza, PO Box 5555, Oakbrook

                                        26


Terrace, Illinois 60181-5555. 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 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

  Holders of shares of the Target Fund are entitled to one vote per share on
matters as to which they are entitled to vote. The Target Fund does not utilize
cumulative voting.

  Each valid proxy given by a shareholder of the Target Fund will be voted by
the persons named in the proxy in accordance with the instructions marked
thereon 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 Board "FOR" approval of the
Reorganization. Abstentions and broker non-votes (i.e., where a nominee, such as
a broker, holding shares for beneficial owners votes on certain matters pursuant
to discretionary authority or instructions from beneficial owners but with
respect to one or more proposals does not receive instructions from beneficial
owners or does not exercise discretionary authority) have the effect of a vote
"AGAINST" the Reorganization proposal because the required vote is a majority of
the outstanding shares. One-half of the outstanding shares entitled to vote on a
proposal must be present in person or by proxy to have a quorum to conduct
business at the Special Meeting. Abstentions and broker non-votes will be deemed
present for quorum purposes.

  Shareholders who execute proxies may revoke them at any time before they are
voted by filing with the Target 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.

  It is not anticipated that any action will be asked of the shareholders of the
Target 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.

  APPROVAL OF THE REORGANIZATION WILL REQUIRE THE FAVORABLE VOTE OF THE HOLDERS
OF A MAJORITY OF THE OUTSTANDING SHARES OF THE TARGET FUND.

  In the event that sufficient votes in favor of a proposal 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

                                        27



permit further solicitation of proxies. If sufficient shares were present to
constitute a quorum, but insufficient votes had been cast in favor of a proposal
to approve it, proxies (including abstentions and broker non-votes) would be
voted in favor of adjournment only if the Board determined that adjournment and
additional solicitation was reasonable and in the best interest of the
shareholders of the Target 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 Target Fund are solicited by the Target Fund
Board. 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 Adviser, Van Kampen, or by dealers or their
representatives. In addition, such solicitation servicing may also be provided
by Management Information Services, a solicitation firm located in Norwell, MA,
at a cost estimated to be approximately $1,500, plus reasonable expenses.


June 24, 2002

                  PLEASE SIGN AND RETURN YOUR PROXY PROMPTLY.

                 YOUR VOTE IS IMPORTANT AND YOUR PARTICIPATION
              IN THE AFFAIRS OF YOUR FUND DOES MAKE A DIFFERENCE.

Risk/Return Summary

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

                              INVESTMENT OBJECTIVE

The Fund's investment objective is to provide investors with a high level of
current income exempt from federal income tax, with liquidity and safety of
principal, primarily through investment in a diversified portfolio of insured
municipal securities.

                        PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund's investment adviser seeks to achieve
the Fund's investment objective by investing substantially all of the Fund's
assets in a portfolio of municipal securities that are insured at the time of
purchase as to timely payment of principal and interest by a top-rated private
insurance company.

The Fund buys and sells municipal securities with a view towards seeking a high
level of current income exempt from federal income taxes and selects securities
which the Fund's investment adviser believes entail reasonable credit risk when
considered in relation to the investment policies of the Fund. In selecting
securities for investment, the Fund's investment adviser uses its research
capabilities to identify and monitor attractive investment opportunities and to
seek to protect the Fund's portfolio from early payment by issuers of such
securities. In conducting its research and analysis, the Fund's investment
adviser considers a number of factors, including general market and economic
conditions, and credit, interest rate and prepayment risks. Portfolio securities
are typically sold when the assessments of the Fund's investment adviser of any
of these factors materially change. Although the Fund invests in insured
municipal securities, insurance does not protect the Fund from market
fluctuations in the value of an insured security, but only guarantees timely
payment of principal and interest of such investments.

Under normal market conditions, the Fund may invest up to 20% of its net assets
in municipal securities that are subject to the federal alternative minimum tax.
Under normal market conditions, up to 10% of the Fund's total assets may be
invested in tax-exempt money market funds which are not insured. The Fund may
purchase and sell securities on a when-issued or delayed delivery basis. The
Fund may purchase and sell certain derivative instruments, such as options,
futures contracts, options on futures contracts and interest rate swaps or other
interest rate-related transactions, for various portfolio management purposes,
including to earn income, facilitate portfolio management and mitigate risks.

                           PRINCIPAL INVESTMENT RISKS

An investment in the Fund is subject to risks, and you could lose money on your
investment in the Fund. There can be no assurance that the Fund will achieve its
investment objective.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Fund will decline. The prices of debt securities tend to fall as
interest rates rise, and such declines tend to be greater among debt securities
with longer maturities. The Fund has no policy limiting the maturities of its
investments. To the extent the Fund invests in securities with longer
maturities, the Fund is subject to greater market risk than a fund investing
solely in shorter-term securities.

Generally, the Fund's municipal securities are insured as to timely payment of
principal and interest by a top-rated private insurance company. This insurance
does not, however, guarantee that the prices of these securities will remain
stable during interest rate changes.

Market risk is often greater among certain types of debt securities, such as
zero coupon bonds. As interest rates change, these securities often fluctuate
more in price than traditional debt securities and may subject the Fund to
greater market risk than a fund that does not own these types of securities.

When-issued and delayed delivery transactions are subject to changes in market
conditions from the time of the commitment until settlement. This may adversely
affect the prices or yields of the securities being purchased. The greater the
Fund's outstanding commitments for these securities, the greater the Fund's
exposure to market price fluctuations.

CREDIT RISK. Credit risk refers to an issuer's ability to make timely payments
of interest and principal. Credit risk should be low for the Fund because it

                                        3


invests substantially all of its assets in insured municipal securities.

INCOME RISK. The income you receive from the Fund is based primarily on interest
rates, which can vary widely over the short- and long-term. If interest rates
drop, your income from the Fund may drop as well.

CALL RISK. If interest rates fall, it is possible that issuers of securities
with high interest rates will prepay or "call" their securities before their
maturity dates. In this event, the proceeds from the called securities would
likely be reinvested by the Fund in securities bearing the new, lower interest
rates, resulting in a possible decline in the Fund's income and distributions to
shareholders.

MUNICIPAL SECURITIES RISK. The Fund invests substantially all of its assets in
insured municipal securities. The yields of municipal securities, or of insured
municipal securities, may move differently and adversely compared to the yields
of the overall debt securities markets. Although the interest received from
municipal securities generally is exempt from federal income tax, the Fund may
invest up to 20% of its net assets in municipal securities subject to the
federal alternative minimum tax. In addition, there could be changes in
applicable tax laws or tax treatments that reduce or eliminate the current
federal income tax exemption on municipal securities or otherwise adversely
affect the current federal or state tax status of municipal securities.

RISKS OF USING DERIVATIVE INSTRUMENTS. In general terms, a derivative instrument
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options, futures contracts, options on futures
contracts and interest rate swaps or other interest rate-related transactions
are examples of derivative instruments. Derivative instruments involve risks
different from direct investments in underlying securities. These risks include
imperfect correlation between the value of the instruments and the underlying
assets; risks of default by the other party to certain transactions; risks that
the transactions may result in losses that partially or completely offset gains
in portfolio positions; and risks that the transactions may not be liquid.

MANAGER RISK. As with any managed fund, the Fund's investment adviser may not be
successful in selecting the best-performing securities or investment techniques,
and the Fund's performance may lag behind that of similar funds.

                                INVESTOR PROFILE

In light of the Fund's investment objective and strategies, the Fund may be
appropriate for investors who:

- - Seek current income

- - Are in a high federal income tax bracket

- - Wish to add to their investment portfolio a fund that invests substantially
  all of its assets in insured municipal securities

An investment in the Fund is not a deposit of any bank or other insured
depository institution. An investment in the Fund is not insured or guaranteed
by the Federal Deposit Insurance Corporation or any other government agency.

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 about the Fund. An investment in the Fund is intended to be a long-
term investment, and the Fund should not be used as a trading vehicle.

                               ANNUAL PERFORMANCE

One way to measure the risks of investing in the Fund is to look at how its
performance has varied from year to year. The following chart shows the annual
returns of the Fund's Class A Shares over the ten calendar years prior to the
date of this Prospectus. Sales loads are not reflected in this chart. If these
sales loads had been included, the returns shown below would have been lower.
Remember that past performance of the Fund is not indicative of its future
performance. As a result of

                                        4


market activity, current performance may vary from the figures shown.

</Table>

The annual return variability of the Fund's Class B Shares and Class C Shares
would be substantially similar to that shown for the Class A Shares because all
of the Fund's shares are invested in the same portfolio of securities; however,
the actual annual returns of the Class B Shares and Class C Shares would be
lower than the annual returns shown for the Fund's Class A Shares because of
differences in the expenses borne by each class of shares.

During the ten-year period shown in the bar chart, the highest quarterly return
for Class A Shares was 7.35% (for the quarter ended March 31, 1995) and the
lowest quarterly return for Class A Shares was -6.08% (for the quarter ended
March 31, 1994).

                            COMPARATIVE PERFORMANCE

As a basis for evaluating the Fund's performance and risks, the table below
shows how the Fund's performance compares with the Lehman Brothers Municipal
Bond Index*, a broad-based market index that the Fund's investment adviser
believes is an appropriate benchmark for the Fund. The Fund's performance
figures listed below include the maximum sales charges paid by investors. The
index's performance figures do not include any commissions or sales charges that
would be paid by investors purchasing the securities represented by the index.
An investment cannot be made directly in the index. Average annual total returns
are shown for the periods ended December 31, 2001 (the most recently completed
calendar year prior to the date of this Prospectus). Remember that past
performance of the Fund is not indicative of its future performance.

(2) Investments of $1 million or more are not subject to any sales charge at the
    time of purchase, but a deferred sales charge of 1.00% may be imposed on
    certain redemptions made within one year of the purchase. See "Purchase of
    Shares -- Class A Shares."

(3) The maximum deferred sales charge is 4.00% in the first year after purchase
    and declining thereafter as follows:

                         Year 1-4.00%
                         Year 2-3.75%

                         After-None

    See "Purchase of Shares -- Class B Shares."

(4) The maximum deferred sales charge is 1.00% in the first year after purchase
    and 0.00% thereafter. See "Purchase of Shares -- Class C Shares."

(5) Class A Shares are subject to an annual service fee of up to 0.25% of the
    average daily net assets attributable to such class of shares. Class B
    Shares and Class C Shares are each subject to a combined annual distribution
    and service fee of up to 1.00% of the average daily net assets attributable
    to such class of shares. See "Purchase of Shares."

(6) Because distribution and/or service (12b-1) fees are paid out of the Fund's
    assets on an ongoing basis, over time these fees will increase the cost of
    your investment and may cost you more than paying other types of sales
    charges.

Example:

The following example is intended to help you compare the cost of investing in
the Fund with the costs of investing in other mutual funds.

The example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods. The
example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same each year (except for the ten-year
amounts for Class B Shares which reflect the conversion of Class B Shares to
Class A Shares eight years after the end of the calendar month in which the
shares were purchased). Although your actual costs may be higher or lower, based
on these assumptions your costs would be:

Investment Objective,
Policies and Risks

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

The Fund's investment objective is to provide investors with a high level of
current income exempt from federal income tax, with liquidity and safety of
principal, primarily through investment in a diversified portfolio of insured
municipal securities. The Fund's investment objective is a fundamental policy
and may not be changed without shareholder approval of a majority of the Fund's
outstanding voting securities, as defined in the Investment Company Act of 1940,
as amended (the "1940 Act"). There are risks inherent in all investments in
securities; accordingly, there can be no assurance that the Fund will achieve
its investment objective.

Under normal market conditions, the Fund's investment adviser seeks to achieve
the Fund's investment objective by investing substantially all of the Fund's
assets in a portfolio of municipal securities that are insured at the time of
purchase as to timely payment of principal and interest by an entity whose
claims-paying ability is rated AAA by Standard and Poor's ("S&P") or Aaa by
Moody's Investors Service, Inc. ("Moody's") or an equivalent rating by another
nationally recognized statistical rating organization ("NRSRO").

The Fund's investment adviser actively manages the Fund's portfolio and adjusts
the average maturity of portfolio investments based upon its expectations about
the direction of interest rates and other economic factors. In selecting
securities for investment, the Fund's investment adviser uses its research
capabilities to identify and monitor attractive investment opportunities and to
seek to protect the Fund's portfolio from early payment by issuers of such
securities. In conducting its research and analysis, the Fund's investment
adviser considers a number of factors, including general market and economic
conditions and credit, interest rate and prepayment risks. Portfolio securities
are typically sold when the assessments of the Fund's investment adviser of any
of these factors materially change. Although the Fund invests in insured
municipal securities, insurance does not protect the Fund from market
fluctuations in the value of an insured security, but only guarantees timely
payment of principal and interest of such investments.

The Fund's investment adviser buys and sells securities for the Fund's portfolio
with a view towards seeking a high level of current income exempt from federal
income tax and selects securities that it believes entail reasonable credit risk
when considered in relation to the investment policies of the Fund. As a result,
the Fund will not necessarily invest in the highest yielding municipal
securities permitted by its investment policies if the Fund's investment adviser
determines that market risks or credit risks associated with such investments
would subject the Fund's portfolio to undue risk. The potential realization of
capital gains or losses resulting from possible changes in interest rates will
not be a major consideration, and frequency of portfolio turnover generally will
not be a limiting factor if the Fund's investment adviser considers it
advantageous to purchase or sell securities.

Under normal market conditions, the Fund may invest up to 20% of its net assets
in municipal securities that are subject to the federal alternative minimum tax.
From time to time, the Fund temporarily may invest up to 10% of its total assets
in tax-exempt money market funds, which are not insured, and such instruments
will be treated as investments in municipal securities. Investments in other
mutual funds may involve duplication of management fees and certain other
expenses.

                              MUNICIPAL SECURITIES

Municipal securities are obligations issued by or on behalf of states,
territories or possessions of the United States, the District of Columbia and
their political subdivisions, agencies and instrumentalities, the interest on
which, in the opinion of bond counsel or other counsel to the issuers of such
securities, is, at the time of issuance, exempt from federal income tax. Under
normal market conditions, the Fund invests at least 80% of its net assets (plus
any borrowings for investment purposes) in municipal securities at the time of
investment. The policy stated in the foregoing sentence is a fundamental policy
of the Fund and may not be changed without shareholder approval of a majority of
the Fund's outstanding voting securities, as defined in the 1940 Act. Under
normal market conditions, the Fund may invest up to 20% of its net assets in
municipal securities that are subject to the federal alternative minimum tax.

                                        7


The issuers of municipal securities obtain funds for various public purposes,
including the construction of a wide range of public facilities such as
airports, highways, bridges, schools, hospitals, housing, mass transportation,
streets and water and sewer works. Other public purposes for which municipal
securities may be issued include refunding outstanding obligations, obtaining
funds for general operating expenses and obtaining funds to lend to other public
institutions and facilities. Certain types of municipal securities are issued to
obtain funding for privately operated facilities.

The yields of municipal securities depend on, among other things, general money
market conditions, general conditions of the municipal securities market, size
of a particular offering, maturity of the obligation and rating of the issue.
The ratings of S&P and Moody's represent their opinions of the quality of the
municipal securities they undertake to rate. It should be emphasized, however,
that ratings are general and are not absolute standards of quality.
Consequently, municipal securities with the same maturity, coupon and rating may
have different yields while municipal securities of the same maturity and coupon
with different ratings may have the same yield.

The two principal classifications of municipal securities are "general
obligation" and "revenue" or "special delegation" securities. "General
obligation" securities are secured by the issuer's pledge of its faith, credit
and taxing power for the payment of principal and interest. "Revenue" securities
are usually payable only from the revenues derived from a particular facility or
class of facilities or, in some cases, from the proceeds of a special excise tax
or other specific revenue source. Industrial development bonds are usually
revenue securities, the credit quality of which is normally directly related to
the credit standing of the industrial user involved.

Within these principal classifications of municipal securities, there are a
variety of types of municipal securities, including fixed and variable rate
securities, municipal notes, variable rate demand notes, municipal leases,
custodial receipts, participation certificates and derivative municipal
securities (which include terms or elements similar to certain strategic
transactions described below). Variable rate securities bear rates of interest
that are adjusted periodically according to formulae intended to reflect market
rates of interest.

The Fund also may invest in derivative variable rate securities, such as inverse
floaters whose rates vary inversely with changes in market rates of interest.
Investment in such securities involves special risks as compared to a fixed rate
municipal security. The extent of increases and decreases in the value of
derivative variable rate securities and the corresponding change to the net
asset value of the Fund generally will be larger than comparable changes in the
value of an equal principal amount of a fixed rate municipal security having
similar credit quality, redemption provisions and maturity. The markets for such
securities may be less developed and have less liquidity than the markets for
conventional municipal securities. The Fund will not invest more than 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
floaters or capped floaters whose rates are subject to periodic or lifetime
caps. 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. Variable rate demand notes are obligations
which contain a floating or variable interest rate adjustment formula and which
are subject to a right of demand for payment of the principal balance plus
accrued interest either at any time or at specified intervals. The interest rate
on a variable rate 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 may be a market rate that is adjusted at specified intervals. The
adjustment formula maintains the value of the variable rate demand note at
approximately the par value of such note at the adjustment date. 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

                                        8


contract. Municipal securities may not be backed by the faith, credit and taxing
power of the issuer. Other than as set forth above, there is no limitation with
respect to the amount of the Fund's assets that may be invested in the foregoing
types of municipal securities. Certain of the municipal securities in which the
Fund may invest represent relatively recent innovations in the municipal
securities markets and the markets for such securities may be less developed
than the market for conventional fixed rate municipal securities. A more
detailed description of the types of municipal securities in which the Fund may
invest is included in the Fund's Statement of Additional Information. The Fund's
Statement of Additional Information may be obtained by investors free of charge
as described on the back cover of this Prospectus.

Under normal market conditions, longer-term municipal securities generally
provide a higher yield than shorter-term municipal securities. The Fund has no
limitation as to the maturity of municipal securities in which it may invest.
The Fund's investment 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.

The net asset value of the Fund will change with changes in the value of its
portfolio securities. Because the Fund invests primarily in fixed income
municipal securities, the net asset value of the Fund can be expected to change
as general levels of interest rates fluctuate. When interest rates decline, the
value of a portfolio invested in fixed income securities generally can be
expected to rise. Conversely, when interest rates rise, the value of a portfolio
invested in fixed income securities generally can be expected to decline. The
prices of longer term municipal securities generally are more volatile with
respect to changes in interest rates than the prices of shorter term municipal
securities. Volatility may be greater during periods of general economic
uncertainty.

Although the Fund invests substantially all of its total assets in municipal
securities that are insured at the time of purchase as to timely payment of
principal and interest, municipal securities, like other debt obligations, are
subject to the credit risk of nonpayment. 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 nonpayment would result in a reduction of income to the Fund, and could
result in a reduction in the value of the municipal securities experiencing
nonpayment and a potential decrease in the net asset value of the Fund. In
addition, the Fund may incur expenses to work out or restructure a distressed or
defaulted security.

The Fund may invest up to 20% of its net assets in municipal securities that are
subject to the federal alternative minimum tax. Accordingly, the Fund may not be
a suitable investment for investors who are already subject to the federal
alternative minimum tax or who could become subject to the federal alternative
minimum tax as a result of an investment in the Fund.

From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the current 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 and the Fund
would re-evaluate its investment objective and policies and consider changes in
its structure.

The Fund generally considers investments in municipal securities not to be
subject to industry concentration policies (issuers of municipal securities as a
group are not an industry) and the Fund may invest in municipal securities
issued by entities having similar characteristics. The issuers may be located in
the same geographic area or may pay their interest obligations from revenue of
similar projects, such as hospitals, airports, utility systems and housing
finance agencies. This may make the Fund's investments more susceptible to
similar economic, political or regulatory occurrences. As the similarity in
issuers increases, the potential for fluctuation in the Fund's net asset value
also increases. The Fund may invest more than 25% of its total assets in a
segment of the municipal securities market with similar characteristics if the
Fund's investment adviser determines that the yields available from obligations
in a particular segment justify the additional risks of a larger investment in
such segment. The Fund may not, however, invest more than 25% of its total
assets in industrial development revenue bonds issued for companies in the same
industry. Sizeable investments

                                        9


in such obligations could involve increased risk to the Fund should any such
issuers or any such related projects or facilities experience financial
difficulties.

The Fund has no policy limiting its investments in municipal securities whose
issuers are located in the same state. However, it is not the present intention
of the Fund to invest more than 25% of the value of its total assets in issuers
located in the same state. If the Fund were to invest more than 25% of its total
assets in issuers located in the same state, the Fund would be more susceptible
to adverse economic, business or regulatory conditions in that state.

From time to time, the Fund's investments may include securities as to which the
Fund, by itself or together with other funds or accounts managed by the Fund's
investment adviser, holds a major portion or all of an issue of municipal
securities. Because there may be relatively few potential purchasers for such
investments and, in some cases, there may be contractual restrictions on
resales, the Fund may find it more difficult to sell such securities at a time
when the Fund's investment adviser believes it is advisable to do so.

                          INSURED MUNICIPAL SECURITIES

The Fund invests substantially all of its assets in a portfolio of municipal
securities that are insured at the time of investment as to timely payment of
principal and interest by a top-rated private insurance company. Under normal
market conditions, the Fund invests at least 80% of its net assets (plus any
borrowings for investment purposes) in insured securities at the time of
investment. The Fund's policy in the foregoing sentence may be changed by the
Fund's Board of Trustees without shareholder approval, but no change is
anticipated; if the Fund's policy in the foregoing sentence changes, the Fund
will notify shareholders at least 60 days prior to implementation of the change
and shareholders should consider whether the Fund remains an appropriate
investment in light of the change. Such insurance could be provided as: Original
Issue Insurance, Secondary Market Insurance or Portfolio Insurance. Original
Issue Insurance is purchased with respect to a particular issue of municipal
securities by the issuer thereof or a third party in conjunction with the
original issue of such municipal securities. Secondary Market Insurance is
purchased by the Fund or a third party subsequent to the time of original
issuance of a municipal security. Both Original Issue Insurance and Secondary
Market Insurance remain in effect as long as the municipal securities covered
thereby remain outstanding and the insurer remains in business, regardless of
whether the Fund ultimately disposes of such municipal securities. Portfolio
Insurance may be purchased by the Fund with respect to municipal securities
which the Fund intends to purchase or already owns and would generally terminate
when the municipal security is sold by the Fund or redeemed. There is no
limitation on the percentage of the Fund's assets that may be invested in
municipal securities insured by any type of insurance or by any given insurer.

Original Issue Insurance, Secondary Market Insurance and Portfolio Insurance
generally do not insure payment on an accelerated basis, the payment of any
redemption premium or the market value of the Fund's portfolio securities. Such
insurance also does not insure against nonpayment of principal or interest on
municipal securities resulting from the insolvency, negligence or any other act
or omission of the trustee or other paying agent for such obligations.

The Fund invests in municipal securities insured by insurers whose claims-paying
ability is rated AAA by S&P, Aaa by Moody's or the equivalent by another NRSRO
at the time of the Fund's investment. A subsequent downgrade by S&P, Moody's or
another NRSRO of an insurer's claims-paying ability may result in increased
credit risk of the municipal securities insured by such insurer and may result
in a downgrade of the rating assigned to the municipal securities insured by
such insurer. The securities could experience a decrease in market price as a
result of such a downgrade. In the event the ratings assigned to such municipal
securities decline to below investment grade, such municipal securities would
probably become less liquid or even illiquid. There can be no assurance that an
insurer will be able to honor its obligations with respect to municipal
securities in the Fund's portfolio. For more information on insurance and a
description of S&P's and Moody's claims-paying ability ratings of insurers, see
the Fund's Statement of Additional Information.

                             DERIVATIVE INSTRUMENTS

The Fund may, but is not required to, use various investment strategic
transactions described below to earn income, facilitate portfolio management and
mitigate risks. Although the Fund's investment adviser

                                        10


seeks to use these transactions to further the Fund's investment objective, no
assurance can be given that the use of these transactions will achieve this
result.

The Fund may purchase and sell derivative instruments such as exchange-listed
and over-the-counter put and call options on securities, financial futures
contracts, fixed-income and other interest rate indices and other financial
instruments, purchase and sell financial futures contracts and options on
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
fluctuations, to protect the Fund's unrealized gains in the value of its
portfolio securities, to facilitate the sale of 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 investment adviser's ability to predict pertinent market
movements, which cannot be assured. The Fund will comply with applicable
regulatory requirements when implementing these strategies, techniques and
instruments.

Strategic Transactions have risks including the imperfect correlation between
the value of such instruments and the underlying assets, the possible default by
the other party to the transaction, the illiquidity of the derivative instrument
and, to the extent that the investment 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 the Strategic Transactions 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 contracts 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 risk management or hedging
instrument may be greater than gains in the value of the Fund's position. In
addition, futures contracts 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 on futures contracts
should tend to minimize the risk of loss due to a decline in the value of the
hedged position, at the same time they tend to limit any potential gain which
might result from an increase in value of such position. Finally, the daily
variation margin requirements for futures contracts would create a greater
ongoing potential financial risk than would purchases of options, where the
exposure is limited to the cost of the initial premium. Losses resulting from
the use of Strategic Transactions would reduce net asset value, and possibly
income, and such losses can be greater than if the Strategic Transactions had
not been utilized. The Strategic Transactions that the Fund may use and their
risks are described more fully in the Fund's Statement of Additional
Information. Income earned or deemed to be earned by the Fund from its Strategic
Transactions, if any, generally will be taxable income of the Fund.

                       OTHER INVESTMENTS AND RISK FACTORS

The Fund may invest in zero coupon securities which are debt securities that do
not entitle the holder to periodic payment of interest prior to maturity or a
specified date when the securities begin paying current interest. Zero coupon
securities are issued and traded at a discount from their face amounts or par
value. The discount varies depending on the time remaining until cash payments
begin, prevailing interest rates, liquidity of the security and the perceived
credit quality of the issuer. Because such securities do not entitle the holder
to any periodic payments of interest prior to maturity, this prevents any
reinvestment of interest payments at prevailing interest rates if prevailing
interest rates rise. On the other hand, because there are no periodic interest
payments to be reinvested prior to maturity, zero coupon securities eliminate
the reinvestment risk and may lock in a favorable rate of return to maturity if

                                        11


interest rates drop. The amount of non-cash interest income earned on
zero-coupon securities is included, for federal income tax purposes, in the
Fund's calculation of income that is required to be distributed to shareholders
for the Fund to maintain its desired federal income tax status (even though such
non-cash paying securities do not provide the Fund with the cash flow with which
to pay such distributions). Accordingly, the Fund may be required to borrow or
to liquidate portfolio securities at a time that it otherwise would not have
done so to make such distributions. The Fund's investment adviser will weigh
these concerns against the expected total returns from such instruments.

The Fund may purchase and sell securities on a "when-issued" and "delayed
delivery" basis whereby the Fund buys or sells a security with payment and
delivery taking place in the future. The payment obligation and the interest
rate are fixed at the time the Fund enters into the commitment. No income
accrues on such securities until to the date the Fund actually takes delivery of
such securities. These transactions are subject to market risk as the value or
yield of a security at delivery may be more or less than the purchase price or
the yield generally available on securities when delivery occurs. In addition,
the Fund is subject to counterparty risk because it relies on the buyer or
seller, as the case may be, to consummate the transaction, and 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. The
Fund will only make commitments to purchase such securities with the intention
of actually acquiring these securities, but the Fund may sell these securities
prior to settlement if it is deemed advisable. No specific limitation exists as
to the percentage of the Fund's assets which may be used to acquire securities
on a "when-issued" and "delayed delivery" basis.

The Fund may invest up to 15% of the Fund's net assets in illiquid securities
and certain restricted securities. Such securities may be difficult or
impossible to sell at the time and the price that the Fund would like. Thus, the
Fund may have to sell such securities at a lower price, sell other securities
instead to obtain cash or forego other investment opportunities.

The Fund may borrow amounts up to 5% of its total assets to pay for redemptions
when liquidation of portfolio securities is considered disadvantageous or
inconvenient and may pledge up to 10% of its total assets to secure such
borrowings.

Further information about these types of investments and other investment
practices that may be used by the Fund is contained in the Fund's Statement of
Additional Information. The Fund's Statement of Additional Information may be
obtained by investors free of charge as described on the back cover of this
Prospectus.

The Fund may sell securities without regard to the length of time they have been
held to take advantage of new investment opportunities, or yield differentials,
or for other reasons. The Fund's portfolio turnover rate may vary from year to
year. A high portfolio turnover rate (100% or more) increases a fund's
transaction costs (including brokerage commissions or dealer costs), which would
adversely impact a fund's performance. Higher portfolio turnover may result in
the realization of more short-term capital gains than if a fund had lower
portfolio turnover. The turnover rate will not be a limiting factor, however, if
the Fund's investment adviser considers portfolio changes appropriate.

TEMPORARY DEFENSIVE STRATEGY. When market conditions dictate a more "defensive"
investment strategy, the Fund may, on a temporary basis, hold cash or invest a
portion or all of its assets in high-quality, short-term municipal securities.
If such municipal securities are not available or, in the judgment of the Fund's
investment adviser, do not afford sufficient protection against adverse market
conditions, the Fund may invest in taxable securities. Such taxable securities
may include securities issued or guaranteed by the U.S. government, its agencies
or instrumentalities, other investment grade quality debt securities, prime
commercial paper, certificates of deposit, bankers' acceptances and other
obligations of domestic banks having total assets of at least $500 million, and
repurchase agreements. In taking such a defensive position, the Fund would
temporarily not be pursuing and may not achieve its investment objective.

Investment
Advisory Services

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

THE ADVISER. Van Kampen Investment Advisory Corp. is the Fund's investment
adviser (the "Adviser" or "Advisory Corp."). The Adviser is a wholly owned
subsidiary of Van Kampen Investments Inc. ("Van Kampen Investments"). Van Kampen
Investments is a diversified asset management company that administers more than
three million retail investor accounts, has extensive capabilities for managing
institutional portfolios and has more than $73 billion under management or
supervision as of December 31, 2001. Van Kampen Investments has more than 50
open-end funds, more than 30 closed-end funds and more than 2,700 unit
investment trusts that are distributed by authorized dealers nationwide. Van
Kampen Funds Inc., the distributor of the Fund (the "Distributor") and the
sponsor of the funds mentioned above, is also a wholly owned subsidiary of Van
Kampen Investments. Van Kampen Investments is an indirect wholly owned
subsidiary of Morgan Stanley Dean Witter & Co. The Adviser's principal office is
located at 1 Parkview Plaza, Oakbrook Terrace, Illinois 60181-5555.

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. Under an investment advisory agreement between the Adviser and the
Fund (the "Advisory Agreement"), the Fund pays the Adviser a monthly fee
computed based upon an annual rate applied to the average daily net assets of
the Fund as follows:

<Table>
<Caption>
    AVERAGE DAILY NET ASSETS  % PER ANNUM
- --------------------------------------------------
                                 
    First $500 million          0.525%
....................................................
    Next $500 million           0.500%
....................................................
    Next $500 million           0.475%
....................................................
    Over $1,500 million         0.450%
....................................................
</Table>

Applying this fee schedule, the effective advisory fee rate was 0.51% of the
Fund's average daily net assets for the Fund's fiscal year ended September 30,
2001. The Fund's average daily net assets are determined by taking the average
of all of the determinations of the net assets during a given calendar month.
Such fee is payable for each calendar month as soon as practicable after the end
of that month.

Under the Advisory Agreement, the Adviser furnishes offices, necessary
facilities and equipment, and provides administrative services to the Fund. The
Fund pays all charges and expenses of its day-to-day operations, including
service fees, distribution fees, custodian fees, legal and independent
accountant fees, the costs of reports and proxies to shareholders, compensation
of trustees of the Fund (other than those who are affiliated persons of the
Adviser, Distributor or Van Kampen Investments) and all other ordinary business
expenses not specifically assumed by the Adviser.

From time to time, the Adviser or the Distributor may voluntarily undertake to
reduce the Fund's expenses by reducing the fees payable to them or by reducing
other expenses of the Fund in accordance with such limitations as the Adviser or
Distributor may establish.

The Adviser may utilize, at its own expense, credit analysis, research and
trading support services provided by its affiliate, Van Kampen Asset Management
Inc. ("Asset Management").

PERSONAL INVESTMENT POLICIES. The Fund, the Adviser and the Distributor have
adopted a Code of Ethics designed to recognize the fiduciary relationships among
the Fund, the Adviser, the Distributor and their respective employees. The Code
of Ethics permits directors, trustees, officers and employees to buy and sell
securities for their personal accounts subject to certain restrictions. Persons
with access to certain sensitive information are subject to pre-clearance and
other procedures designed to prevent conflicts of interest.

PORTFOLIO MANAGEMENT. The Fund is managed by the Adviser's Investment Grade
Municipal team. The team is made up of established investment professionals.
Current members of the team include James F. Willison, a Managing Director of
the Adviser, Joseph R. Arcieri, an Executive Director of the Adviser and Joseph
A. Piraro, a Vice President of the Adviser. The composition of the team may
change without notice from time to time.

Purchase of Shares

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

                                    GENERAL

This Prospectus offers three classes of shares of the Fund, designated as Class
A Shares, Class B Shares and Class C Shares. Other classes of shares of the Fund
may be offered through one or more separate prospectuses of the Fund. By
offering multiple classes of shares, the Fund permits each investor to choose
the class of shares that is most beneficial given the type of investor, the
amount to be invested and the length of time the investor expects to hold the
shares.

Each class of shares represents an interest in the same portfolio of investments
of the Fund and has the same rights except that (i) Class A Shares generally
bear the sales charge expenses at the time of purchase while Class B Shares and
Class C Shares generally bear the sales charge expenses at the time of
redemption and any expenses (including higher distribution fees and transfer
agency costs) resulting from such deferred sales charge arrangement, (ii) each
class of shares has exclusive voting rights with respect to approvals of the
Rule 12b-1 distribution plan and the service plan (each as described below)
under which the class's distribution fee and/or the service fee is paid, (iii)
each class of shares has different exchange privileges, (iv) certain classes of
shares are subject to a conversion feature and (v) certain classes of shares
have different shareholder service options available.

The offering price of the Fund's shares is based upon the Fund's net asset value
per share (plus sales charges, where applicable). The net asset values per share
of the Class A Shares, Class B Shares and Class C Shares are generally expected
to be substantially the same. In certain circumstances, however, the per share
net asset values of the classes of shares may differ from one another,
reflecting the daily expense accruals of the higher distribution fees and
transfer agency costs applicable to the Class B Shares and Class C Shares and
the differential in the dividends that may be paid on each class of shares.

The net asset value per share for each class of shares of the Fund is determined
once daily as of the close of trading on the New York Stock Exchange (the
"Exchange") (currently 4:00 p.m., New York time) each day the Exchange is open
for trading 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's Board of Trustees reserves the right to calculate the net
asset value per share and adjust the offering price more frequently than once
daily if deemed desirable. Net asset value per share for each class is
determined by dividing the value of the Fund's portfolio securities, cash and
other assets (including accrued interest) attributable to such class, less all
liabilities (including accrued expenses) attributable to such class, by the
total number of shares of the class outstanding. Portfolio securities are valued
by using market quotations, prices provided by market makers or estimates of
market values determined in good faith based upon yield data relating to
instruments or securities with similar characteristics in accordance with
procedures established by the Board of Trustees of the Fund. Securities for
which market quotations are not readily available and other assets are valued at
their fair value as determined in good faith by the Adviser in accordance with
procedures established by the Fund's Board of Trustees. Securities with
remaining maturities of 60 days or less are valued at amortized cost, which
approximates market value. See the financial statements and notes thereto in the
Fund's Statement of Additional Information.

The Fund has adopted a distribution plan (the "Distribution Plan") with respect
to each of its Class A Shares, Class B Shares and Class C Shares pursuant to
Rule 12b-1 under the 1940 Act. The Fund also adopted a service plan (the
"Service Plan") with respect to each such class of its shares. Under the
Distribution Plan and the Service Plan, the Fund pays distribution fees in
connection with the sale and distribution of its shares and service fees in
connection with the provision of ongoing services to shareholders of each such
class and the maintenance of shareholder accounts.

The amount of distribution fees and service fees varies among the classes
offered by the Fund. Because these fees are paid out of the Fund's assets on an
ongoing basis, these fees will increase the cost of your investment in the Fund.
By purchasing a class of shares subject to higher distribution fees and service
fees, you may pay more over time than on a class of shares with other types of
sales charge arrangements. Long-term

                                        14


shareholders may pay more than the economic equivalent of the maximum front-end
sales charges permitted by the rules of the National Association of Securities
Dealers, Inc. ("NASD"). The net income attributable to a class of shares will be
reduced by the amount of the distribution fees and service fees and other
expenses of the Fund associated with that class of shares. To assist investors
in comparing classes of shares, the tables under the Prospectus heading "Fees
and Expenses of the Fund" provide a summary of sales charges and expenses and an
example of the sales charges and expenses of the Fund applicable to each class
of shares offered herein.

The shares are offered on a continuous basis through the Distributor as
principal underwriter, which is located at 1 Parkview Plaza, Oakbrook Terrace,
Illinois 60181-5555. Shares may be purchased through members of the NASD who are
acting as securities dealers ("dealers") and NASD members or eligible non-NASD
members who are acting as brokers or agents for investors ("brokers"). "Dealers"
and "brokers" are sometimes referred to herein as "authorized dealers."

Shares may be purchased on any business day by completing the account
application form and forwarding the account application form, directly or
through an authorized dealer, to the Fund's shareholder service agent, Van
Kampen Investor Services Inc. ("Investor Services"), a wholly owned subsidiary
of Van Kampen Investments. When purchasing shares of the Fund through this
Prospectus, investors must specify whether the purchase is for Class A Shares,
Class B Shares or Class C Shares by selecting the correct Fund number on the
account application form. Sales personnel of authorized dealers distributing the
Fund's shares are entitled to receive compensation for selling such shares and
may receive differing compensation for selling Class A Shares, Class B Shares or
Class C Shares.

The offering price for shares is based upon the next calculation of net asset
value per share (plus sales charges, where applicable) after an order is
received by Investor Services. Orders received by authorized dealers prior to
the close of the Exchange are priced based on the date of receipt provided such
order is transmitted to Investor Services prior to Investor Services' close of
business on such date. Orders received by authorized dealers after the close of
the Exchange or transmitted to Investor Services after its close of business are
priced based on the date of the next determined net asset value per share
provided they are received by Investor Services prior to Investor Services'
close of business on such date. It is the responsibility of authorized dealers
to transmit orders received by them to Investor Services so they will be
received in a timely manner.

The Fund and the Distributor reserve the right to refuse any order for the
purchase of shares. The Fund also reserves the right to suspend the sale of the
Fund's shares in response to conditions in the securities markets or for other
reasons. Shares of the Fund may be sold in foreign countries where permissible.

Investor accounts will automatically be credited with additional shares of the
Fund after any Fund distributions, such as dividends and capital gain dividends,
unless the investor instructs the Fund otherwise. Investors wishing to receive
cash instead of additional shares should contact the Fund by telephone at (800)
341-2911 or by writing to the Fund, c/o Van Kampen Investor Services Inc., PO
Box 218256, Kansas City, MO 64121-8256.

There is no minimum investment amount when establishing an account with the
Fund. However, the Fund may redeem any shareholder account (other than
retirement accounts and accounts established through a broker for which the
transfer agent does not have discretion to initiate transactions) that has been
open for one year or more and has a balance of less than $1,000. Shareholders
will receive written notice at least 60 days in advance of any involuntary
redemption and will be given the opportunity to purchase at net asset value
without sales charge the number of additional shares needed to bring the account
value to $1,000. There will be no involuntary redemption if the value of the
account is less than $1,000 due to market depreciation.

                                 CLASS A SHARES

Class A Shares of the Fund are sold at net asset value plus an initial maximum
sales charge of up to 4.75% of the offering price (or 4.99% of the net amount
invested), reduced on investments of $100,000 or more as follows:

* No sales charge is payable at the time of purchase on investments of $1
  million or more, although for such investments the Fund may impose a
  contingent deferred sales charge of 1.00% on certain redemptions made within
  one year of the purchase. The contingent deferred sales charge is assessed on
  an amount equal to the lesser of the then current market value or the cost of
  the shares being redeemed. Accordingly, no sales charge is imposed on
  increases in net asset value above the initial purchase price.

No sales charge is imposed on Class A Shares received from reinvestment of
dividends or capital gain dividends.

Under the Distribution Plan and the Service Plan, the Fund may spend up to a
total of 0.25% per year of the Fund's average daily net assets with respect to
Class A Shares of the Fund. From such amount, under the Service Plan, the Fund
may spend up to 0.25% per year of the Fund's average daily net assets with
respect to Class A Shares of the Fund.

                                 CLASS B SHARES

Class B Shares of the Fund are sold at net asset value and are subject to a
contingent deferred sales charge if redeemed within six years of purchase as
shown in the table as follows:

The contingent deferred sales charge is assessed on an amount equal to the
lesser of the then current market value or the cost of the shares being
redeemed. Accordingly, no sales charge is imposed on increases in net asset
value above the initial purchase price. In addition, no sales charge is assessed
on shares derived from reinvestment of dividends or capital gain dividends. The
Fund will generally not accept a purchase order for Class B Shares in the amount
of $100,000 or more.

The amount of the contingent deferred sales charge, if any, varies depending on
the number of years from the time of payment for each purchase of Class B Shares
until the time of redemption of such shares.

In determining whether a contingent deferred sales charge applies to a
redemption, it is assumed that the shares being redeemed first are any shares in
the shareholder's Fund account that are not subject to a contingent deferred
sales charge, followed by shares held the longest in the shareholder's account.

Under the Distribution Plan, the Fund may spend up to 0.75% per year of the
Fund's average daily net assets with respect to Class B Shares of the Fund. In
addition, under the Service Plan, the Fund may spend up to

                                        16


0.25% per year of the Fund's average daily net assets with respect to Class B
Shares of the Fund.

                                 CLASS C SHARES

Class C Shares of the Fund are sold at net asset value and are subject to a
contingent deferred sales charge of 1.00% of the dollar amount subject to charge
if redeemed within one year of purchase.

The contingent deferred sales charge is assessed on an amount equal to the
lesser of the then current market value or the cost of the shares being
redeemed. Accordingly, no sales charge is imposed on increases in net asset
value above the initial purchase price. In addition, no sales charge is assessed
on shares derived from reinvestment of dividends or capital gain dividends. The
Fund will not accept a purchase order for Class C Shares in the amount of $1
million or more.

In determining whether a contingent deferred sales charge applies to a
redemption, it is assumed that the shares being redeemed first are any shares in
the shareholder's Fund account that are not subject to a contingent deferred
sales charge, followed by shares held the longest in the shareholder's account.

Under the Distribution Plan, the Fund may spend up to 0.75% per year of the
Fund's average daily net assets with respect to Class C Shares of the Fund. In
addition, under the Service Plan, the Fund may spend up to 0.25% per year of the
Fund's average daily net assets with respect to Class C Shares of the Fund.

                               CONVERSION FEATURE

Class B Shares purchased on or after June 1, 1996, including Class B Shares
received from reinvestment of distributions through the dividend reinvestment
plan, automatically convert to Class A Shares eight years after the end of the
calendar month in which the shares were purchased. Class B Shares purchased
before June 1, 1996, including Class B Shares received from reinvestment of
distributions through the dividend reinvestment plan, automatically convert to
Class A Shares seven years after the end of the calendar month in which the
shares were purchased. Class C Shares purchased before January 1, 1997,
including Class C Shares received from reinvestment of distributions through the
dividend reinvestment plan, automatically convert to Class A Shares ten years
after the end of the calendar month in which the shares were purchased. Such
conversion will be on the basis of the relative net asset values per share,
without the imposition of any sales load, fee or other charge. The conversion
schedule applicable to a share of the Fund acquired through the exchange
privilege from another Van Kampen fund participating in the exchange program is
determined by reference to the Van Kampen fund from which such share was
originally purchased.

The conversion of such shares to Class A Shares is subject to the continuing
availability of an opinion of counsel to the effect that (i) the assessment of
the higher distribution fee and transfer agency costs with respect to such
shares does not result in the Fund's dividends or capital gain dividends
constituting "preferential dividends" under the federal income tax law and (ii)
the conversion of shares does not constitute a taxable event under federal
income tax law. The conversion may be suspended if such an opinion is no longer
available and such shares might continue to be subject to the higher aggregate
fees applicable to such shares for an indefinite period.

                              WAIVER OF CONTINGENT
                             DEFERRED SALES CHARGE

The contingent deferred sales charge is waived on redemptions of Class B Shares
and Class C Shares (i) within one year following the death or disability (as
disability is defined by federal income tax law) of a shareholder, (ii) for
required minimum distributions from an individual retirement account ("IRA") or
certain other retirement plan distributions, (iii) for withdrawals under the
Fund's systematic withdrawal plan but limited to 12% annually of the initial
value of the account, (iv) if no commission or transaction fee is paid to
authorized dealers at the time of purchase of such shares and (v) if made by the
Fund's involuntary liquidation of a shareholder's account as described herein.
Subject to certain limitations, a shareholder who has redeemed Class C Shares of
the Fund may reinvest in Class C Shares at net asset value with credit for any
contingent deferred sales charge if the reinvestment is made within 180 days
after the redemption provided that shares of the Fund are available for sale at
the time of reinvestment. For a more complete description of contingent deferred
sales charge waivers, please refer to the Fund's Statement of Additional
Information or contact your authorized dealer.

                               QUANTITY DISCOUNTS

Investors purchasing Class A Shares may, under certain circumstances described
below, be entitled to pay reduced or no sales charges. Investors, or their
authorized dealers, must notify the Fund at the time of the purchase order
whenever a quantity discount is applicable to purchases. Upon such notification,
an investor will pay 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 authorized dealer or the Distributor.

A person eligible for a reduced sales charge includes an individual, his or her
spouse and children under 21 years of age and any corporation, partnership or
sole proprietorship which is 100% owned, either alone or in combination, by any
of the foregoing; a trustee or other fiduciary purchasing for a single trust or
for a single fiduciary account, or a " company" as defined in Section 2(a)(8) of
the 1940 Act.

As used herein, "Participating Funds" refers to certain open-end investment
companies advised by Asset Management or Advisory Corp. and distributed by the
Distributor as determined from time to time by the Fund's Board of Trustees.

VOLUME DISCOUNTS. The size of investment shown in the Class A Shares sales
charge table applies to the total dollar amount being invested by any person in
shares of the Fund, or in any combination of shares of the Fund and shares of
other Participating Funds, although other Participating Funds may have different
sales charges.

CUMULATIVE PURCHASE DISCOUNT. The size of investment shown in the Class A Shares
sales charge table may also be determined by combining the amount being invested
in shares of the Participating Funds plus the current offering price of all
shares of the Participating Funds currently owned.

LETTER OF INTENT. A Letter of Intent provides an opportunity for an investor to
obtain a reduced sales charge by aggregating investments over a 13-month period
to determine the sales charge as outlined in the Class A Shares sales charge
table. The size of investment shown in the Class A Shares sales charge table
includes purchases of shares of the Participating Funds in Class A Shares over a
13-month period based on the total amount of intended purchases plus the value
of all shares of the Participating Funds previously purchased and still owned.
An investor may elect to compute the 13-month period starting up to 90 days
before the date of execution of a Letter of Intent. Each investment made during
the period receives the reduced sales charge applicable to the total amount of
the investment goal. The Letter of Intent does not preclude the Fund (or any
other Participating Fund) from discontinuing the sale of its shares. The initial
purchase must be for an amount equal to at least 5% of the minimum total
purchase amount of the level selected. If trades not initially made under a
Letter of Intent subsequently qualify for a lower sales charge through the
90-day backdating provisions, an adjustment will be made at the expiration of
the Letter of Intent to give effect to the lower sales charge. Such adjustment
in sales charge will be used to purchase additional shares. The Fund initially
will escrow shares totaling 5% of the dollar amount of the Letter of Intent to
be held by Investor Services in the name of the shareholder. In the event the
Letter of Intent goal is not achieved within the specified period, the investor
must pay the difference between the sales charge applicable to the purchases
made and the reduced sales charges previously paid. Such payments may be made
directly to the Distributor or, if not paid, the Distributor will liquidate
sufficient escrowed shares to obtain the difference.

                            OTHER PURCHASE PROGRAMS

Purchasers of Class A Shares may be entitled to reduced or no initial sales
charges in connection with the unit investment trust reinvestment program and
purchases by registered representatives of selling firms or purchases by persons
affiliated with the Fund or the Distributor. The Fund reserves the right to
modify or terminate these arrangements at any time.

UNIT INVESTMENT TRUST REINVESTMENT PROGRAM. The Fund permits unitholders of unit
investment trusts to reinvest distributions from such trusts in Class A Shares
of the Fund at net asset value without 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
other investments made from unit investment 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 authorized dealer, if any, through which such

                                        18


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 terms and conditions
that apply to the program, should contact their authorized dealer or the
Distributor.

The administrator of such a unit investment trust must have an agreement with
the Distributor pursuant to which the administrator will (1) submit a single
bulk order and make payment with a single remittance for all investments in the
Fund during each distribution period by all investors who choose to invest in
the Fund through the program and (2) provide Investor Services with appropriate
backup data for each investor participating in the program in a computerized
format fully compatible with Investor Services' processing system.

To obtain these special benefits, all dividends and other distributions from the
Fund must be reinvested in additional shares and there cannot be any systematic
withdrawal program. The Fund will send account activity statements to such
participants on a quarterly basis only, even if their investments are made more
frequently. The Fund reserves the right to modify or terminate this program at
any time.

NET ASSET VALUE PURCHASE OPTIONS. Class A Shares of the Fund may be purchased at
net asset value without sales charge, generally upon written assurance that the
purchase is made for investment purposes and that the shares will not be resold
except through redemption by the Fund, by:

 (1) Current or retired trustees or directors of funds advised by Morgan Stanley
     Dean Witter & Co. and any of its subsidiaries and such persons' families
     and their beneficial accounts.

 (2) Current or retired directors, officers and employees of Morgan Stanley Dean
     Witter & Co. and any of its subsidiaries; employees of an investment
     subadviser to any fund described in (1) above or an affiliate of such
     subadviser; and such persons' families and their beneficial accounts.

 (3) Directors, officers, employees and, when permitted, registered
     representatives, of financial institutions that have a selling group
     agreement with the Distributor and their spouses and children under 21
     years of age when purchasing for any accounts they beneficially own, or, in
     the case of any such financial institution, when purchasing for retirement
     plans for such institution's employees; provided that such purchases are
     otherwise permitted by such institutions.

 (4) Registered investment advisers who charge a fee for their services, trust
     companies and bank trust departments investing on their own behalf or on
     behalf of their clients. The Distributor may pay authorized dealers through
     which purchases are made an amount up to 0.50% of the amount invested, over
     a 12-month period.

 (5) Trustees and other fiduciaries purchasing shares for retirement plans which
     invest in multiple fund families through broker-dealer retirement plan
     alliance programs that have entered into agreements with the Distributor
     and which are subject to certain minimum size and operational requirements.
     Trustees and other fiduciaries should refer to the Statement of Additional
     Information for further details with respect to such alliance programs.

 (6) Beneficial owners of shares of Participating Funds held by a retirement
     plan or held in a tax-advantaged retirement account who purchase shares of
     the Fund with proceeds from distributions from such a plan or retirement
     account other than distributions taken to correct an excess contribution.

 (7) Accounts as to which a bank or broker-dealer charges an account management
     fee ("wrap accounts"), provided the bank or broker-dealer has a separate
     agreement with the Distributor.

 (8) Trusts created under pension, profit sharing or other employee benefit
     plans qualified under Section 401(a) of the Internal Revenue Code of 1986,
     as amended (the "Code"), or custodial accounts held by a bank created
     pursuant to Section 403(b) of the Code and sponsored by nonprofit
     organizations defined under Section 501(c)(3) of the Code and assets held
     by an employer or trustee in connection with an eligible deferred
     compensation plan under

                                        19


     Section 457 of the Code. Such plans will qualify for purchases at net asset
     value provided, for plans initially establishing accounts with the
     Distributor in the Participating Funds after January 1, 2000, that (a) the
     total plan assets are at least $1 million or (b) such shares are purchased
     by an employer sponsored plan with more than 100 eligible employees. Such
     plans that have been established with a Participating Fund or have received
     proposals from the Distributor prior to January 1, 2000 based on net asset
     value purchase privileges previously in effect will be qualified to
     purchase shares of the Participating Funds at net asset value. Section
     403(b) and similar accounts for which Van Kampen Trust Company serves as
     custodian will not be eligible for net asset value purchases based on the
     aggregate investment made by the plan or the number of eligible employees,
     except under certain uniform criteria established by the Distributor from
     time to time. A commission will be paid to authorized dealers who initiate
     and are responsible for such purchases within a rolling twelve-month period
     as follows: 1.00% on sales to $2 million, plus 0.80% on the next $1
     million, plus 0.50% on the next $47 million, plus 0.25% on the excess over
     $50 million.

 (9) Individuals who are members of a "qualified group." For this purpose, a
     qualified group is one which (i) has been in existence for more than six
     months, (ii) has a purpose other than to acquire shares of the Fund or
     similar investments, (iii) has given and continues to give its endorsement
     or authorization, on behalf of the group, for purchase of shares of the
     Fund and Participating Funds, (iv) has a membership that the authorized
     dealer can certify as to the group's members and (v) satisfies other
     uniform criteria established by the Distributor for the purpose of
     realizing economies of scale in distributing such shares. A qualified group
     does not include one whose sole organizational nexus, for example, is that
     its participants are credit card holders of the same institution, policy
     holders of an insurance company, customers of a bank or broker-dealer,
     clients of an investment adviser or other similar groups. Shares purchased
     in each group's participants account in connection with this privilege will
     be subject to a contingent deferred sales charge of 1.00% in the event of
     redemption within one year of purchase, and a commission will be paid to
     authorized dealers who initiate and are responsible for such sales to each
     individual as follows: 1.00% on sales to $2 million, plus 0.80% on the next
     $1 million and 0.50% on the excess over $3 million.

(10)Certain qualified state tuition plans qualifying pursuant to Section 529 of
    the Code ("Section 529 Plans") that are approved by the Fund's Distributor.
    There is no minimum investment amount for purchases made under this option
    (10).

The term "families" includes a person's spouse, children and grandchildren under
21 years of age, parents and the parents of the person's spouse.

Purchase orders made pursuant to clause (4) may be placed either through
authorized dealers as described above or directly with Investor Services by the
investment adviser, trust company or bank trust department, provided that
Investor Services receives federal funds for the purchase by the close of
business on the next business day following acceptance of the order. An
authorized dealer 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. Authorized dealers will be paid a service fee as described above
on purchases made under options (3) through (10) above. The Fund may terminate,
or amend the terms of, offering shares of the Fund at net asset value to such
groups at any time.

Redemption of Shares

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

Generally, shareholders may redeem for cash some or all of their shares without
charge by the Fund (other than applicable sales charge) at any time. As
described under the Prospectus heading "Purchase of Shares," redemptions of
Class B Shares and Class C Shares may be subject to a contingent deferred sales
charge. In addition, certain redemptions of Class A Shares for shareholder
accounts of $1 million or more may be subject to a contingent deferred sales
charge. Redemptions completed through an authorized dealer or a
custodian/trustee of a retirement plan account may

                                        20


involve additional fees charged by the dealer or custodian/trustee.

Except as specified below under "Telephone Redemption Requests," payment for
shares redeemed generally will be made by check mailed within seven days after
receipt by Investor Services of the redemption request and any other necessary
documents in proper form as described below. Such payment may be postponed or
the right of redemption suspended as provided by the rules of the SEC. Such
payment may, under certain circumstances, be paid wholly or in part by a
distribution-in-kind of portfolio securities. A distribution-in-kind may result
in recognition by the shareholder of a gain or loss for federal income tax
purposes when such securities are distributed, and the shareholder may have
brokerage costs and a gain or loss for federal income tax purposes upon the
shareholder's disposition of such securities. If the shares to be redeemed have
been recently purchased by check, Investor Services may delay the payment of
redemption proceeds until it confirms that the purchase check has cleared, which
may take up to 15 calendar days from the date of purchase. A taxable gain or
loss may be recognized by the shareholder upon redemption of shares.

WRITTEN REDEMPTION REQUESTS. Shareholders may request a redemption of shares by
written request in proper form sent directly to Van Kampen Investor Services
Inc., PO Box 218256, Kansas City, MO 64121-8256. The request for redemption
should indicate the number of shares or dollar amount to be redeemed, the Fund
name and class designation of such shares and the shareholder's account number.
The redemption request must be signed by all persons in whose names the shares
are registered. Signatures must conform exactly to the account registration. If
the proceeds of the redemption exceed $100,000, 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 15 calendar days, signature(s) must be guaranteed by
one of the following: a bank or trust company; a broker-dealer; a credit union;
a national securities exchange, registered securities association or clearing
agency; a savings and loan association; or a federal savings bank.

Generally, a properly signed written request with any required signature
guarantee is all that is required for a redemption request to be in proper form.
In some cases, however, additional documents may be necessary. Certificated
shares may be redeemed only by written request. The certificates for the shares
being redeemed must be properly endorsed for transfer. Generally, in the event a
redemption is requested by and registered to a corporation, partnership, trust,
fiduciary, estate or other legal entity owning shares of the Fund, a copy of the
corporate resolution or other legal documentation appointing the authorized
signer and certified within the prior 120 calendar days must accompany the
redemption request. Retirement plan distribution requests should be sent to the
plan custodian/trustee to be forwarded to Investor Services. Contact the plan
custodian/trustee for further information.

In the case of written redemption requests sent directly to Investor Services,
the redemption price is the net asset value per share next determined after the
request in proper form is received by Investor Services.

AUTHORIZED DEALER REDEMPTION REQUESTS. Shareholders may place redemption
requests through an authorized dealer following procedures specified by such
authorized dealer. The redemption price for such shares is the net asset value
per share next calculated after an order in proper form is received by an
authorized 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
authorized dealers to transmit redemption requests received by them to the
Distributor so they will be received prior to such time. Redemptions completed
through an authorized dealer may involve additional fees charged by 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. A shareholder
automatically has telephone redemption privileges unless the shareholder
indicates otherwise by checking the applicable box on the account application
form. For accounts that are not established with telephone redemption
privileges, a shareholder may call the Fund at (800) 341-2911 to request that a
copy of the Telephone Redemption Authorization form be sent to the shareholder
for completion. Shares may be redeemed by calling (800) 341-2911, our automated
telephone system,

                                        21


which is generally accessible 24 hours a day, seven days a week. Van Kampen
Investments and its subsidiaries, including Investor Services, 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, none of Van Kampen Investments, Investor Services or
the Fund will be liable for following telephone instructions which it reasonably
believes to be genuine. Telephone redemptions may not be available if the
shareholder cannot reach Investor Services 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 procedure previously described.
Requests received by Investor Services prior to 4:00 p.m., New York time, will
be processed at the next determined net asset value per share. These privileges
are available for most accounts other than retirement accounts or accounts with
shares represented by certificates. If an account has multiple owners, Investor
Services may rely on the instructions of any one owner.

For redemptions authorized by telephone, amounts of $50,000 or less may be
redeemed daily if the proceeds are to be paid by check and amounts of at least
$1,000 up to $1 million may be redeemed daily if the proceeds are to be paid by
wire. The proceeds must be payable to the shareholder(s) of record and sent to
the address of record for the account or wired directly to their predesignated
bank account. This privilege is not available if the address of record has been
changed within 15 calendar days prior to a telephone redemption request.
Proceeds from redemptions payable by wire transfer are expected to be wired on
the next business day following the date of redemption. The Fund reserves the
right at any time to terminate, limit or otherwise modify this redemption
privilege.

Distributions from
the Fund

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

In addition to any increase in the value of shares which the Fund may achieve,
shareholders may receive distributions from the Fund of dividends and capital
gain dividends.

DIVIDENDS. Interest from investments is the Fund's main source of net investment
income. The Fund's present policy, which may be changed at any time by the
Fund's Board of Trustees, is to declare daily and distribute monthly as
dividends to shareholders all, or substantially all, of this net investment
income. Dividends are automatically applied to purchase additional shares of the
Fund at the next determined net asset value unless the shareholder instructs
otherwise.

The per share dividends on Class B Shares and Class C Shares may be lower than
the per share dividends on Class A Shares as a result of the higher distribution
fees and transfer agency costs applicable to such classes of shares.

CAPITAL GAIN DIVIDENDS. The Fund may realize capital gains or losses when it
sells securities, depending on whether the sales prices for the securities are
higher or lower than purchase prices. The Fund distributes any net capital gain
to shareholders as capital gain dividends at least annually. As in the case of
dividends, capital gain dividends are automatically reinvested in additional
shares of the Fund at the next determined net asset value unless the shareholder
instructs otherwise.

please refer to the Fund's Statement of Additional Information or contact your
authorized dealer.

INTERNET TRANSACTIONS. In addition to performing transactions on your account
through written instruction or by telephone, you may also perform certain
transactions through the internet. Please refer to our web site at
www.vankampen.com for further instructions regarding internet transactions. Van
Kampen Investments and its subsidiaries, including Investor Services, and the
Fund employ procedures considered by them to be reasonable to confirm that
instructions communicated through the internet are genuine. Such procedures
include requiring use of a personal identification number prior to acting upon
internet instructions and providing written confirmation of instructions
communicated through the internet. If reasonable procedures are employed, none
of Van Kampen Investments, Investor Services or the Fund will be liable for
following instructions received through the internet which it reasonably
believes to be genuine. If an account has multiple owners, Investor Services may
rely on the instructions of any one owner.

REINVESTMENT PLAN. A convenient way for investors to accumulate additional
shares is by accepting dividends and capital gain dividends in shares of the
Fund. Such shares are acquired at net asset value per share (without sales
charge) on the applicable payable date of the dividend or capital gain dividend.
Unless the shareholder instructs otherwise, the reinvestment plan is automatic.
This instruction may be made by telephone by calling (800) 341-2911 ((800)
421-2833 for the hearing impaired) or by writing to Investor Services. The
investor may, on the account application form or prior to any declaration,
instruct that dividends and/or capital gain dividends be paid in cash, be
reinvested in the Fund at the next determined net asset value or be reinvested
in another Participating Fund at the next determined net asset value.

AUTOMATIC INVESTMENT PLAN. An automatic investment plan is available under which
a shareholder can authorize Investor Services to debit the shareholder's bank
account on a regular basis to invest predetermined amounts in the Fund.
Additional information is available from the Distributor or your authorized
dealer.

CHECK WRITING PRIVILEGE. A Class A shareholder holding shares of the Fund for
which certificates have not been issued and which are not in escrow may write
checks against such shareholder's account by completing the Authorization for
Redemption by Check form and the appropriate section of the account application
form and returning the forms to Investor Services. Once the forms are properly
completed, signed and returned, a supply of checks (redemption drafts) will be
sent to the Class A shareholder. Checks can be written to the order of any
person in any amount of $100 or more.

When a check is presented to the custodian bank, State Street Bank & Trust
Company (the "Bank"), for payment, full and fractional Class A Shares required
to cover the amount of the check are redeemed from the shareholder's Class A
Shares account by Investor Services at the next determined net asset value per
share. Check writing redemptions represent the sale of Class A Shares. Any gain
or loss realized on the redemption of shares is a taxable event.

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 Shares account, the
check will be returned and the shareholder may be subject to additional charges.
A shareholder may not liquidate the entire account by means of a check. The
check writing privilege may be terminated or suspended at any time by the Fund
or by the Bank and neither shall incur any liability for such amendment or
termination or for effecting redemptions to pay checks reasonably believed to be
genuine or for returning or not paying on checks which have not been accepted
for any reason. Retirement plans and accounts that are subject to backup
withholding are not eligible for the check writing privilege.

EXCHANGE PRIVILEGE. Shares of the Fund may be exchanged for shares of the same
class of any Participating Fund based on the next determined net asset value per
share of each fund after requesting the exchange without any sales charge,
subject to certain limitations. Shares of the Fund may be exchanged for shares
of any Participating Fund only if shares of that

                                        23


Participating Fund are available for sale. Shareholders seeking an exchange into
a Participating Fund should obtain and read the current prospectus for such fund
prior to implementing an exchange. A prospectus of any of the Participating
Funds may be obtained from an authorized dealer or the Distributor.

To be eligible for exchange, shares of the Fund must have been registered in the
shareholder's name for at least 30 days prior to an exchange. Shares of the Fund
registered in a shareholder's name for less than 30 days may only be exchanged
upon receipt of prior approval of the Adviser. It is the policy of the Adviser,
under normal circumstances, not to approve such requests.

When shares that are subject to a contingent deferred sales charge are exchanged
among Participating Funds, the holding period for purposes of computing the
contingent deferred sales charge is based upon the date of the initial purchase
of such shares from a Participating Fund. When such shares are redeemed and not
exchanged for shares of another Participating Fund, the shares are subject to
the contingent deferred sales charge schedule imposed by the Participating Fund
from which such shares were originally purchased.

Exchanges of shares are sales of shares of one Participating Fund and purchases
of shares of another Participating Fund. The sale may result in a gain or loss
for federal income tax purposes. If the shares sold have been held for less than
91 days, the sales charge paid on such shares 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 Investor Services, by calling (800) 341-2911, our automated telephone system,
which is generally accessible 24 hours a day, seven days a week, or through the
internet at www.vankampen.com. A shareholder automatically has these exchange
privileges unless the shareholder indicates otherwise by checking the applicable
box on the account application form. Van Kampen Investments and its
subsidiaries, including Investor Services, 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,
none of Van Kampen Investments, Investor Services or the Fund will be liable for
following telephone instructions which it reasonably believes to be genuine. 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 gain dividend options (except dividend diversification) and
authorized dealer of record as the account from which shares are exchanged,
unless otherwise specified by the shareholder. In order to establish a
systematic withdrawal plan for the new account or reinvest dividends from the
new account into another fund, however, an exchanging shareholder must submit a
specific request.

The Fund reserves the right to reject any order to purchase its shares through
exchange or otherwise. Certain patterns of past exchanges and/or purchase or
sale transactions involving the Fund or other Participating Funds may result in
the Fund limiting or prohibiting, in the Fund's discretion, additional purchases
and/or exchanges. Determinations in this regard may be made based on the
frequency or dollar amount of the previous exchanges or purchases or sale
transactions. Generally, all shareholders are limited to a maximum of eight
exchanges per fund during a rolling 365-day period. Exchange privileges will be
suspended on a particular fund if more than eight exchanges out of that fund are
made by a shareholder during a rolling 365-day period. If exchange privileges
are suspended, subsequent exchange requests during the stated period will not be
processed. Exchange privileges will be restored when the account history shows
fewer than eight exchanges in the rolling 365-day period. This eight exchange
policy does not apply to money market funds, systematic exchange plans or
employer-sponsored retirement plans. The Fund may modify, restrict or terminate
the exchange privilege at any time. Shareholders will receive 60 days' notice of
any termination or material amendment.

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

                                        24


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 such shareholder's 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 of the fund which the
shareholder is redeeming will be redeemed at the net asset value per share next
determined on the date of receipt. Shares of the fund that the shareholder is
purchasing 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 that shares of the
funds involved in the request are priced will be processed on the next business
day in the manner described herein.

Federal Income Taxation

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

The Fund intends to invest in sufficient tax-exempt municipal securities to
permit payment of "exempt-interest dividends" (as defined under applicable
federal income tax law). The aggregate amount of dividends designated as
exempt-interest dividends cannot exceed, however, the excess of 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
taxable 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.

Exempt-interest dividends paid to shareholders generally are not includable in
the shareholders' gross income for federal income tax purposes. Exempt-interest
dividends are included in determining what portion, if any, of a person's social
security and railroad retirement benefits will be includable in gross income
subject to federal income tax.

Under applicable federal income tax law, the interest on certain municipal
securities may be an item of tax preference subject to the federal alternative
minimum tax. The Fund may invest a portion of its assets in municipal securities
subject to this provision so that a portion of its exempt-interest dividends may
be an item of tax preference to the extent such dividends represent interest
received from such municipal securities. Accordingly, investment in the Fund
could cause shareholders to be subject to (or result in an increased liability
under) the federal alternative minimum tax.

Although exempt-interest dividends from the Fund generally may be treated by
shareholders as interest excluded from their gross income, each shareholder is
advised to consult his or her tax adviser with respect to whether
exempt-interest dividends retain this exclusion given the shareholder's
particular tax circumstances. For example, exempt-interest dividends may not be
excluded if the shareholder would be treated as a "substantial user" (or a
"related person" of a substantial user, as each term is defined by applicable
federal income tax law) of the facilities financed with respect to any of the
tax-exempt obligations held by the Fund.

If the Fund distributes exempt-interest dividends during the shareholder's
taxable year, some or all of the interest on indebtedness incurred or continued
by a shareholder to purchase or carry shares of the Fund will not be deductible
for federal income tax purposes, depending upon the ratio of exempt-interest
dividends to the total of exempt-interest dividends plus taxable dividends
received by the shareholder (excluding capital gain dividends) during the 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 loss on the sale or
exchange of the shares will be disallowed to the extent of the amount of such
exempt-interest dividend.

While the Fund expects that a major portion of its income will constitute
tax-exempt interest, a portion of the Fund's income may consist of investment
company taxable income (generally ordinary income and net short-term capital
gain, but not net capital gain, which is the excess of net long-term capital
gain over net

                                        25


short-term capital loss). Distributions of investment company taxable income are
taxable to shareholders as ordinary income to the extent of the Fund's earnings
and profits, whether paid in cash or reinvested in additional shares.
Distributions of the Fund's net capital gain as capital gain dividends, if any,
are taxable to shareholders as long-term capital gain, whether paid in cash or
reinvested in additional shares, and regardless of how long the shares of the
Fund have been held by such shareholders. Fund distributions generally will not
qualify for the corporate dividends received deduction.

Distributions in excess of the Fund's earnings and profits will first reduce the
adjusted tax basis of a shareholder's shares and, after such adjusted tax basis
is reduced to zero, will constitute capital gains to such shareholder (assuming
such shares are held as a capital asset). Although distributions generally are
treated as taxable in the year they are paid, distributions declared in October,
November or December, payable to shareholders of record on a specified date in
such month and paid during January of the following year will be treated as
having been distributed by the Fund and received by the shareholders on the
December 31st prior to the date of payment. The Fund will inform shareholders of
the source and tax status of all distributions promptly after the close of each
calendar year.

The sale or exchange of shares may be a taxable transaction for federal income
tax purposes. Shareholders who sell their shares will generally recognize a gain
or loss in an amount equal to the difference between their adjusted tax basis in
the shares sold and the amount received. If the shares are held by the
shareholder as a capital asset, the gain or loss will be a capital gain or loss.
Any recognized capital gains may be taxed at different rates depending on how
long the shareholder held the shares.

Backup withholding rules require the Fund, in certain circumstances, to withhold
a percentage of dividends and certain other payments, including redemption
proceeds 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 make certain required certifications or who are otherwise
subject to backup withholding.

The Fund intends to qualify as a regulated investment company under federal
income tax law. If the Fund so qualifies and distributes each year to its
shareholders at least an amount equal to the sum of 90% of its investment
company taxable income and 90% of its net tax-exempt interest income, the Fund
will not be required to pay federal income taxes on any income it distributes to
shareholders. If the Fund distributes less than an amount equal to the sum of
98% of its ordinary income and 98% of its capital gain net income, then the Fund
will be subject to a 4% excise tax on the undistributed amounts.

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

        deferred sales charge ("CDSC"). On purchases of $1 million or more, a
        CDSC of 1% may be imposed on certain redemptions made within one year of
        purchase. If the sales charges were included, total returns would be
        lower. These returns include combined Rule 12b-1 fees and service fees

        include payment of the maximum CDSC of 4%, charged on certain
        redemptions made within one year of purchase and declining to 0% after

        lower. These returns include combined Rule 12b-1 fees and service fees
        of 1% and do not reflect the deduction of taxes that a shareholder would
        pay on Fund distributions or the redemption of Fund shares.

        Expenses and Net Investment Income to Average Net Assets due to the
        Adviser's reimbursement of certain expenses was less than 0.01%.

     As of the date of this Statement of Additional Information, each
trustee/director holds the same position with each of 57 operating open-end
funds in the Fund Complex (the "Open-End Fund Complex").



COMMITTEES



     During the Fund's last fiscal year, the Fund had three standing committees
(an audit committee, a brokerage and services committee and a retirement plan
committee) and one ad hoc committee (a nominating


                                        5



committee). The Fund's audit committee consists of J. Miles Branagan, Jerry D.
Choate and R. Craig Kennedy. The audit committee makes recommendations to the
Fund's Board of Trustees concerning the selection of the Fund's independent
public accountants, reviews with such accountants the scope and results of the
Fund's annual audit and considers any comments which the accountants may have
regarding the Fund's financial statements, books of account or internal
controls. The Fund's brokerage and services committee consists of Linda Hutton
Heagy, Jack E. Nelson and Suzanne H. Woolsey. The brokerage and services
committee reviews the Fund's allocation of brokerage transactions and
soft-dollar practices and reviews the transfer agency and shareholder servicing
arrangements with Investor Services. The Fund's retirement plan committee
consists of Linda Hutton Heagy, R. Craig Kennedy and Jack E. Nelson. The
retirement plan committee is responsible for reviewing the terms of the Fund's
retirement plan and reviews any administrative matters which arise with respect
thereto. During the Fund's last fiscal year, the audit committee of the Fund
held 2 meetings and the brokerage and services committee of the Fund held 5
meetings. The retirement plan committee of the Fund does not meet on a regular
basis, but does meet on an ad hoc basis as necessary to administer the
retirement plan. The trustees of the Fund who are not "interested persons" of
the Fund (as defined by the 1940 Act) select and nominate any other
non-interested trustees of the Fund. The Fund has an ad hoc nominating committee
currently consisting of J. Miles Branagan, Linda Hutton Heagy and R. Craig
Kennedy. While the non-interested trustees of the Funds expect to be able to
continue to identify from their own resources an ample number of qualified
candidates for the Board of Trustees as they deem appropriate, they will review
nominations from shareholders to fill any vacancies. Nominations from
shareholders should be in writing and addressed to the non-interested trustees
at the Fund's office.



     As of December 31, 2001, each trustee of the Fund beneficially owned equity
securities of the Fund and of all of the funds in the Open-End Fund Complex
overseen by the trustee in the dollar range amounts specified below.

APPROVAL OF ADVISORY AGREEMENT



     In approving the Advisory Agreement, the Board of Trustees, including the
non-interested Trustees, considered the nature, quality and scope of the
services provided by the Adviser and the Subadviser, the performance, fees and
expenses of the Fund compared to other similar investment companies, the
Adviser's expenses in providing the services and the profitability of the
Adviser and its affiliated companies. The Board of Trustees also reviewed the
benefit to the Adviser and the Subadviser of receiving third party research paid
for by Fund assets and the propriety of such an arrangement and evaluated other
benefits the Adviser and the Subadviser derives from their relationship with the
Fund. The Board of Trustees considered the extent to which any economies of
scale experienced by the Adviser are shared with the Fund's shareholders, and
the propriety of existing and alternative breakpoints in the Fund's advisory fee
schedule. The Board of Trustees considered comparative advisory fees of the Fund
and other investment companies at different asset levels, and considered the
trends in the industry versus historical and projected sales and redemptions of
the Fund. The Board of Trustees reviewed reports from third parties about the
foregoing factors and considered changes, if any, in such items since its
previous approval. The Board of Trustees discussed the financial strength of the
Adviser, the Subadviser and their affiliated companies and the capability of the
personnel of the Adviser and the Subadviser. The Board of Trustees reviewed the
statutory and regulatory requirements for approval of advisory agreements. The
Board of Trustees, including the non-interested Trustees, evaluated all of the
foregoing and determined, in the exercise of its business judgment, that
approval of the Advisory Agreement and the Subadvisory Agreement were in the
best interests of the Fund and its shareholders.

consult with each other before issuing any press releases or otherwise making
any public statements with respect to this Agreement or the transactions
contemplated herein and shall not issue any 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 Acquiring Fund nor the Target Fund shall take
any action, or

                                       14





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 Acquiring Fund and the
Target Fund will take such action, or cause such action to be taken, as is
reasonably necessary to enable Skadden, Arps, Slate, Meagher & Flom (Illinois),
counsel to the Target Fund, to render the tax opinion required herein.

         L. DECLARATION OF DIVIDEND. At or immediately prior to the Closing
Date, the Target Fund shall declare and pay to its shareholders 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.

competent jurisdiction or other legal restraint or prohibition (an "Injunction")
preventing the consummation of the transactions contemplated by this Agreement

government agency or entity asking any of the foregoing be pending. There shall
not have been any action taken or any statute, rule, regulation or order
enacted, entered, enforced or deemed applicable to the transactions contemplated
by this Agreement, which makes the consummation of the transactions contemplated
by this Agreement illegal or which has a material adverse effect on business

         F. TAX OPINION. The Target Fund shall have obtained an opinion from

dated as of the Closing Date, addressed to the Target Fund, that the
consummation of the transactions set forth in this Agreement comply with the
requirements of a reorganization as described in Section 368(a) of the Code.

         G. OPINION OF COUNSEL. The Target Fund shall have received the opinion
of Skadden, Arps, Slate, Meagher & Flom (Illinois), counsel for the Acquiring
Fund, dated as of the Closing Date, addressed to the Target Fund substantially
in the form and to the effect that: (i) the Acquiring Fund is existing in good
standing under the laws of its state of organization; (ii) the Acquiring Fund is
registered as an open-end, management investment company under the 1940 Act;
(iii) this Agreement and the reorganization provided for herein and the
execution of this Agreement have been duly authorized and approved by all
requisite action of the Acquiring Fund and this Agreement has been duly executed
and delivered by the Acquiring Fund and (assuming the Agreement is a valid and
binding obligation of the other parties thereto) is a valid and binding
obligation of the Acquiring Fund; (iv) neither the execution or delivery by the
Acquiring Fund of this Agreement nor the consummation by the Acquiring Fund of
the transactions contemplated thereby contravene the Acquiring Fund's
organizational documents, or, to the knowledge of such counsel, violate any
provision of any statute or any published regulation or any judgment or order
disclosed to counsel by the Acquiring Fund as being applicable to the Acquiring
Fund; (v) to their knowledge based solely on the certificate of an appropriate
officer of the Acquiring Fund attached thereto, there is no pending or
threatened litigation except as described therein; (vi) the Acquiring Fund's
Shares

                                       16





have been duly authorized and upon issuance thereof in accordance with this
Agreement will be validly issued, fully paid and nonassessable; (vii) 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 the Acquiring 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 SEC 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
Acquiring 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 (viii)
to their knowledge and subject to the qualifications set forth below, the
execution and delivery by the Acquiring Fund of the Agreement and the
consummation of the transactions therein contemplated do not require, under the
laws of the state of organization or any state in which the Acquiring Fund is
qualified to do business 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 Target Fund of any material
benefit under the Agreement; or (c) which can be readily obtained without
significant delay or expense to the Target Fund, without loss to the Target Fund
of any material benefit under the Agreement and without any material adverse
effect on the Target 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 state of organization or any state in which
the Acquiring Fund is qualified to do business and the federal laws of the
United States 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 counsel by the Acquiring Fund in connection with the
opinion. In addition, although counsel need not have specifically considered the
possible applicability to the Acquiring Fund of any other laws, orders or
judgments,

                                       17


nothing has come to their attention in connection with their representation of
the Acquiring 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 Target Fund shall have received a
certificate of an authorized officer of the Acquiring Fund, 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 Acquiring Fund Board.

consummation of the Reorganization are subject to the satisfaction, or written
waiver by the Acquiring Fund of the following conditions:

results of operations, business, properties or assets of the Target Fund, and
the Acquiring Fund shall have received a certificate of an authorized officer of
the Target Fund satisfactory in form and substance to the Acquiring Fund so
stating. The Target Fund shall have performed and complied in all material
respects with all agreements, obligations and covenants required by this
Agreement to be so performed or complied with by them on or prior to the Closing
Date.

         C. REGISTRATION STATEMENT EFFECTIVE. The Registration Statement shall
have become effective and no stop orders under the Securities Act pertaining
thereto shall have been issued.

         D. REGULATORY APPROVAL. All necessary approvals, registrations, and
exemptions under federal and state securities laws shall have been obtained.


                                       18

         E. NO INJUNCTIONS OR RESTRAINTS: ILLEGALITY. No injunction preventing
the consummation of the transactions contemplated by this Agreement shall be in
effect, nor shall any proceeding by any state, local or federal government
agency or entity seeking any of the foregoing be pending. There shall not be any
action taken, or any statute, rule, regulation or order enacted, entered,
enforced or deemed applicable to the transactions contemplated by this
Agreement, which makes the consummation of the transactions contemplated by this
Agreement illegal.

         F. TAX OPINION. The Acquiring Fund shall have obtained an opinion from
Skadden, Arps, Slate, Meagher & Flom (Illinois), counsel for the Target Fund,
dated as of the Closing Date, addressed to the Acquiring Fund, that the
consummation of the transactions set forth in this Agreement comply with the
requirements of a reorganization as described in Section 368(a) of the Code.

         G. OPINION OF COUNSEL. The Acquiring Fund shall have received the
opinion of Skadden, Arps, Slate, Meagher & Flom (Illinois), counsel for the
Target Fund, dated as of the Closing Date, addressed to the Acquiring Fund,
substantially in the form and to the effect that: (i) the Target Fund is duly
formed and existing under the laws of its state of organization; (ii) the Target
Fund is registered as an open-end, management investment company under the
1940 Act; (iii) this Agreement and the reorganization provided for herein and
the execution of this Agreement have been duly authorized by all requisite
action of the Target Fund and this Agreement has been duly executed and
delivered by the Target Fund and (assuming the Agreement is a valid and binding
obligation of the other party thereto) is a valid and binding obligation of the
Target Fund; (iv) neither the execution or delivery by the Target Fund of this
Agreement nor the consummation by the Target Fund of the transactions
contemplated thereby contravene the Target Fund's organizational documents or,
to its knowledge, violate any provision of any statute, or any published
regulation or any judgment or order disclosed to them by the Target Fund as
being applicable to the Target Fund; (v) to its knowledge based solely on the
certificate of an appropriate officer of the Target Fund attached thereto, there
is no pending, or threatened litigation involving the Target Fund except as
disclosed therein; (vi) 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 the Target 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 SEC thereunder and no facts have come to counsel's attention
which cause them to believe that as of the effectiveness of the portions of the

                                       19


Registration Statement applicable to the Target 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 (vii) to their knowledge and subject to the
qualifications set forth below, the execution and delivery by the Tax Free Trust
on behalf of the Target Fund of the Agreement and the consummation of  the
transactions therein contemplated do not require, under the laws of the state of
organization or any state in which the Target Fund is qualified to do business,
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 under the
Securities Act, the 1940 Act or the rules and regulations thereunder.) 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 Acquiring Fund of any material benefit
under such agreements; or (c) which can be readily obtained without significant
delay or expense to the Acquiring Fund, without loss to the Acquiring Fund of
any material benefit under the Agreement and without any material adverse effect
on them 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 the opinion, (b)
laws of the state of organization or any state in which the Target Fund is
qualified to do business and the federal laws of the United States which, in
such counsel's experience, are normally applicable to transactions of the type
provided for in the Agreement and (c) court orders and judgments disclosed to
them by the Target Fund in connection with the opinion. In addition, although
counsel need not have specifically considered the possible applicability to the
Target Fund of any other laws, orders or judgments, nothing has come to their
attention in connection with their representation of the Target Fund in this
transaction that has caused them to conclude that any other consent, approval,
authorization, registration, qualification, order or filing is required.

         H. THE ASSETS. The Assets, as set forth in Schedule 1, as amended,
shall consist solely of securities which are in conformity with the Acquiring
Fund's investment objectives, policies and restrictions as set forth in the
Acquiring Fund's Prospectus, a copy of which has been delivered to the Target

are true and correct on the Closing Date, together with certified copies of the
resolutions adopted by the Target Fund Board and shareholders.

9. AMENDMENT, WAIVER AND TERMINATION.

         (A) The parties hereto may, by agreement in writing authorized by the
respective Boards, amend this Agreement at any time before or after approval
thereof by the shareholders of the Target Fund; provided, however, that after

parties hereto which substantially changes the terms of Sections 1, 2 and 3
hereof without obtaining Target Fund's shareholder approval thereof.

         (B) At any time prior to the Closing Date, either of the parties may by
written instrument signed by it (i) waive any inaccuracies in the
representations and warranties made to it contained herein and (ii) waive
compliance with any of the covenants or conditions made for its benefit
contained herein. No delay on the part of either party in exercising any right,
power or privilege hereunder shall operate as a waiver thereof, nor shall any
waiver on the part of any party of any such right, power or privilege, or any
single or partial exercise of any such right, power or privilege, preclude any
further exercise thereof or the exercise of any other such right, power or
privilege.

         (C) This Agreement may be terminated, and the transactions contemplated
herein may be abandoned at any time prior to the Closing Date:

         (i) by the mutual consents of the respective Boards of the Target Fund
and the Acquiring Fund;

respect any of its representations, warranties, covenants or agreements
contained in this Agreement;

                                       21

material respect any of its representations, warranties, covenants or agreements
contained in this Agreement;

         (iv) by either the Target Fund or Acquiring Fund, if the Closing has
not occurred on or prior to December 31, 2002 (provided that the rights to
terminate this Agreement pursuant to this subsection (C)(iv) shall not be
available to any party whose failure to fulfill any of its obligations under
this Agreement has been the cause of or resulted in the failure of the Closing
to occur on or before such date);

         (v) by the Acquiring Fund in the event that: (a) all the conditions
precedent to the Target Fund's obligation to close, as set forth in Section 7 of
this Agreement, have been fully satisfied (or can be fully satisfied at the
Closing); (b) the Acquiring Fund gives the Target Fund written assurance of its
intent to close irrespective of the satisfaction or nonsatisfaction of all
conditions precedent to the Acquiring Fund's obligation to close, as set forth
in Section 8 of this Agreement; and (c) the Target Fund then fails or refuses to
close within the earlier of five (5) business days or December 31, 2002; or

         (vi) by the Target Fund in the event that: (a) all the conditions
precedent to the Acquiring Fund's obligation to close, as set forth in Section 8
of this Agreement, have been fully satisfied (or can be fully satisfied at the
Closing); (b) the Target Fund gives the Acquiring Fund written assurance of its
intent to close irrespective of the satisfaction or nonsatisfaction of all the

close within the earlier of five (5) business days or December 31, 2002.

         In the event of termination of this Agreement by either or both of the
Target Fund and Acquiring Fund pursuant to Section 9(C), written notice thereof
shall forthwith be given by the terminating party to the other party hereto, and
this Agreement shall therefore terminate and become void and have no effect, and
the transactions contemplated herein and thereby shall be abandoned, without
further action by the parties hereto.

11. SURVIVAL OF WARRANTIES AND INDEMNIFICATION.

         A. SURVIVAL. The representations and warranties included or provided



                                       22





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 Acquiring Fund's and the Target
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 Acquiring Fund or the Target 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, trustees, 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 give written notice to Indemnitor within



                                       23





the earlier of ten (10) days of receipt of written notice to Indemnified Party
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 prior written
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.

13. NOTICES.

         All notices hereunder shall be sufficiently given for all purposes
hereunder if in writing and delivered personally or sent by registered mail or
certified mail, postage prepaid. Notice to the Target Fund shall be addressed to

parties hereto and their successors and assigns. This Agreement shall not be

terms of the Agreement between the parties and may not be amended, modified or
changed or terminated orally. This Agreement may be executed in one or more

                                                          TFIN SAI 1/02

                              GENERAL INFORMATION

     The Trust is an unincorporated business trust established under the laws of
the State of Delaware by an Agreement and Declaration of Trust (the "Declaration
of Trust") dated May 10, 1995. The Trust was originally organized in 1985 under
the name Van Kampen Merritt Tax Free Trust as a Massachusetts business trust
(the "Massachusetts Trust"). The Massachusetts Trust was reorganized into the
Trust under the name Van Kampen American Capital Tax Free Trust on July 31,
1995. The Trust was created for the purpose of facilitating the Massachusetts
Trust reorganization into a Delaware business trust. On July 14, 1998, the Trust
adopted its current name.

     The Fund was originally organized as a Maryland corporation under the name
Van Kampen Merritt Insured Tax Free Fund Inc. The Fund was subsequently
reorganized as a sub-trust of the Massachusetts Trust under the name Van Kampen
Merritt Insured Tax Free Income Fund as of February 22, 1998. The Fund was
reorganized as a series of the Trust under the name Van Kampen American Capital
Insured Tax Free Fund on July 31, 1995. On July 14, 1998, the Fund adopted its
current name.

     Van Kampen Investment Advisory Corp. (the "Adviser" or "Advisory Corp."),
Van Kampen Funds Inc. (the "Distributor"), and Van Kampen Investor Services Inc.
("Investor Services") are wholly owned subsidiaries of Van Kampen Investments
Inc. ("Van Kampen Investments"), which is an indirect wholly owned subsidiary of
Morgan Stanley Dean Witter & Co. ("Morgan Stanley"). The principal office of the
Trust, the Fund, the Adviser, the Distributor and Van Kampen Investments is
located at 1 Parkview Plaza, Oakbrook Terrace, Illinois 60181-5555. The
principal office of Investor Services is located at 7501 Tiffany Springs
Parkway, Kansas City, Missouri 64153.

     Morgan Stanley is a preeminent global financial services firm that
maintains leading market positions in each of its three primary businesses:
securities, asset management and credit services.

     The authorized capitalization of the Trust consists of an unlimited number
of shares of beneficial interest, par value $0.01 per share, which can be
divided into series, such as the Fund, and further subdivided into classes of
each series. 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 currently offers three classes of shares, designated as Class A
Shares, Class B Shares and Class C Shares. Other classes may be established from
time to time in accordance with the provisions of the Declaration of Trust. Each
class of shares of the Fund generally is identical in all respects except that
each class of shares is subject to its own sales charge schedule and its own
distribution expenses. Each class of shares also has exclusive voting rights
with respect to its distribution fee.

     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 and separate votes are taken by each class of a series on matters
affecting an individual class of such series. For example, a change in
investment policy for a series would be voted upon by shareholders of only the
series involved and a change in the distribution fee for a class of a series
would be voted upon by shareholders of only the class of such series involved.
Except as otherwise described in the Prospectus or herein, shares do not have
cumulative voting rights, preemptive rights or any conversion, subscription or
exchange rights.

     The Trust does not contemplate holding regular meetings of shareholders to
elect Trustees or otherwise. However, the holders of 10% or more of the
outstanding shares may by written request require a meeting to consider the
removal of Trustees by a vote of two-thirds of the shares then outstanding cast
in person or by proxy at such meeting. The Fund will assist such holders in
communicating with other shareholders of the Fund to the extent required by the
Investment Company Act of 1940, as amended (the "1940 Act"), or rules or
regulations promulgated by the Securities and Exchange Commission ("SEC").

                                       B-2


     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 debts and expenses of the
Fund have been paid. Since Class B Shares and Class C Shares have higher
distribution fees and transfer agency costs, the liquidation proceeds to holders
of Class B Shares and Class C Shares are likely to be less than the liquidation
proceeds to holders of Class A Shares.

     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
outstanding and entitled to vote (or such higher vote as may be required by the
1940 Act or other applicable law) and except that the Trustees cannot amend the
Declaration of Trust to impose any liability on shareholders, make any
assessment on shares or impose liabilities on the Trustees without approval from
each affected shareholder or Trustee, as the case may be.

     Statements contained in this Statement of Additional Information as to the
contents of any contract or other document referred to are not necessarily
complete, and, in each instance, reference is made to the copy of such contract
or other document filed as an exhibit to the Registration Statement of which
this Statement of Additional Information forms a part, each such statement being
qualified in all respects by such reference.

     As of January 8, 2002, no person was known by the Fund to own beneficially
or to hold of record 5% or more of the outstanding Class A Shares, Class B
Shares or Class C Shares of the Fund, except as follows:

                    INVESTMENT OBJECTIVE, POLICIES AND RISKS

     The following disclosure supplements the disclosure set forth under the
same caption in the Prospectus and does not, standing alone, present a complete
or accurate explanation of the matters disclosed. Readers must refer also to
this caption in the Prospectus for a complete presentation of the matters
disclosed below.

MUNICIPAL SECURITIES

     Municipal securities include long-term obligations, which often are 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

                                       B-3


securities. The Fund may, however, invest in shorter term municipal securities
when yields are greater than yields available on longer term municipal
securities, for temporary defensive purposes or when redemption requests are
expected. The two principal classifications of municipal securities are "general
obligation" and "revenue" or "special obligation" securities, which include
"industrial revenue bonds." 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 or special obligation securities 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. The Fund
may also invest in "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.

     Also included within the general category of municipal securities are
participations in lease obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of state and local
governments or authorities used to finance the acquisition of equipment and
facilities. Lease obligations generally do not constitute general obligations of
the municipality for which the municipality's taxing power is pledged. A lease
obligation is ordinarily backed by the municipality's covenant to budget for,
appropriate and make the payments due under the lease obligation. However,
certain lease obligations contain "non-appropriation" clauses which provide that
the municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a
yearly basis. A risk exists that the municipality will not, or will be unable
to, appropriate money in the future in the event of political changes, changes
in the economic viability of the project, general economic changes or for other
reasons. In addition to the "non-appropriation" risk, these securities represent
a relatively new type of financing that has not yet developed the depth of
marketability associated with more conventional bonds. Although
"non-appropriation" lease obligations are often secured by an assignment of the
lessee's interest in the leased property, management and/or disposition of the
property in the event of foreclosure could be costly, time consuming and result
in unsatisfactory recoupment of the Fund's original investment. Additionally,
use of the leased property may be limited by state or local law to a specified
use thereby further limiting ability to rent. There is no limitation on the
percentage of the Fund's assets that may be invested in "non-appropriation"
lease obligations. In evaluating such lease obligations, the Adviser will
consider such factors as it deems appropriate, which factors may include (a)
whether the lease can be cancelled, (b) the ability of the lease obligee to
direct the sale of the underlying assets, (c) the general creditworthiness of
the lease obligor, (d) the likelihood that the municipality will discontinue
appropriating funding for the leased property in the event such property is no
longer considered essential by the municipality, (e) the legal recourse of the
lease obligee in the event of such a failure to appropriate funding and (f) any
limitations which are imposed on the lease obligor's ability to utilize
substitute property or services than those covered by the lease obligation.

     Also included in the term municipal securities are participation
certificates issued by state and local governments or authorities to finance the
acquisition of equipment and facilities. They may represent participations in a
lease, an installment purchase contract or a conditional sales contract.

     The Fund may purchase floating and variable rate demand notes, which are
municipal securities normally having a stated maturity in excess of one year,
but which permit the holder to demand payment of principal at any time or at
specified intervals. The issuer of such notes normally has a corresponding
right, after a given period, to prepay at its discretion upon notice to the
noteholders the outstanding principal amount of the notes plus accrued interest.
The interest rate on a floating rate demand note is based on a known lending
rate, such as a bank's prime rate, and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is adjusted
automatically at specified intervals.

     The Fund also may invest up to 15% of its total assets in derivative
variable rate municipal securities such as inverse floaters whose rates vary
inversely with changes in market rates of interest or range floaters or capped
floaters whose rates are subject to periodic or lifetime caps. Derivative
variable rate 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 variable rate securities in response to changes in market
rates of interest generally

                                       B-4


will be larger than comparable changes in the value of an equal principal amount
of a fixed rate municipal security having similar credit quality, redemption
provisions and maturity.

     The Fund also may acquire custodial receipts or certificates underwritten
by securities dealers or banks that evidence ownership of future interest
payments, principal payments or both on certain municipal securities. The
underwriter of these certificates or receipts typically purchases municipal
securities and deposits the securities in an irrevocable trust or custodial
account with a custodian bank, which then issues receipts or certificates that
evidence ownership of the periodic unmatured coupon payments and the final
principal payment on the obligations. Although under the terms of a custodial
receipt, the Fund typically would be authorized to assert its rights directly
against the issuer of the underlying obligation, the Fund could be required to
assert through the custodian bank those rights as may exist against the
underlying issuer. Thus, in the event the underlying issuer fails to pay
principal or interest when due, the Fund may be subject to delays, expenses and
risks that are greater than those that would have been involved if the Fund had
purchased a direct obligation of the issuer. In addition, in the event that the
trust or custodial account in which the underlying security has been deposited
is determined to be an association taxable as a corporation, instead of a
non-taxable entity, the yield on the underlying security would be reduced in
recognition of any taxes paid.

     The "issuer" of municipal securities generally is deemed to be the
governmental agency, authority, instrumentality or other political subdivision,
or the non-governmental user of a revenue bond-financed facility, the assets and
revenues of which will be used to meet the payment obligations, or the guarantor
of such payment obligations, of the municipal securities.

     Although the Fund invests substantially all of its assets in municipal
securities insured as to timely payment of principal and interest, municipal
securities, like other debt obligations, are subject to the risk of non-payment.
The ability of issuers of municipal securities to make timely payments of
interest and principal may be adversely impacted in general economic downturns
and as relative governmental cost burdens are allocated and reallocated among
federal, state and local governmental units. Such non-payment would result in a
reduction of income to the Fund, and could result in a reduction in the value of
the municipal security experiencing non-payment and a potential decrease in the
net asset value of the Fund. Issuers of municipal securities might seek
protection under the bankruptcy laws. In the event of bankruptcy of such an
issuer, the Fund could experience delays and limitations with respect to the
collection of principal and interest on such municipal securities and the Fund
may not, in all circumstances, be able to collect all principal and interest to
which it is entitled. To enforce its rights in the event of a default in the
payment of interest or repayment of principal, or both, the Fund may take
possession of and manage the assets securing the issuer's obligations on such
securities, which may increase the Fund's operating expenses and adversely
affect the net asset value of the Fund. Any income derived from the Fund's
ownership or operation of such assets may not be tax-exempt. In addition, the
Fund's intention to qualify as a "regulated investment company" under the
Internal Revenue Code of 1986, as amended (the "Code"), may limit the extent to
which the Fund may exercise its rights by taking possession of such assets,
because as a regulated investment company the Fund is subject to certain
limitations on its investments and on the nature of its income. Further, in
connection with the working out or restructuring of a defaulted security, the
Fund may acquire additional securities of the issuer, the acquisition of which
may be deemed to be a loan of money or property. Such additional securities
should be considered speculative with respect to the capacity to pay interest or
repay principal in accordance with their terms.

INSURANCE

     As described in the Prospectus, the Fund invests substantially all of its
assets in municipal securities which are either pre-insured under a policy
obtained for such securities prior to the purchase of such securities or are
insured under policies obtained by the Fund to cover otherwise uninsured
securities.

     ORIGINAL ISSUE INSURANCE. Original Issue Insurance is purchased with
respect to a particular issue of municipal securities by the issuer thereof or a
third party in conjunction with the original issuance of such municipal
securities. Under such insurance, the insurer unconditionally guarantees to the
holder of the insured municipal security the timely payment of principal and
interest on such obligation when and as such payments shall become due but shall
not be paid by the issuer; except that in the event of any acceleration of the
due

                                       B-5


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 insured payments may be made in such amounts and at such times as
payments of principal would have been due had there not been such acceleration.
The insurer is responsible for such payments less any amounts received by the
holder from any trustee for the municipal security issuers or from any other
source. Original Issue Insurance generally does not insure payment on an
accelerated basis, the payment of any redemption premium (except with respect to
certain premium payments in the case of certain small issue industrial
development and pollution control municipal securities), the value of the shares
of the Fund or the market value of municipal securities, or payments of any
tender purchase price upon the tender of the municipal securities. Original
Issue Insurance also does not insure against nonpayment of principal of or
interest on municipal securities resulting from the insolvency, negligence or
any other act or omission of the trustee or other paying agent for such
obligations.

     In the event that interest on or principal of a municipal security covered
by insurance is due for payment but is unpaid by reason of nonpayment by the
issuer thereof, the applicable insurer will make payments to its fiscal agent
(the "Fiscal Agent") equal to such unpaid amounts of principal and interest not
later than one business day after the insurer has been notified that such
nonpayment has occurred (but not earlier than the date of such payment is due).
The Fiscal Agent will disburse to the Fund the amount of principal and interest
which is then due for payment but is unpaid upon receipt by the Fiscal Agent of
(i) evidence of the Fund's right to receive payment of such principal and
interest and (ii) evidence, including any appropriate instrument of assignment,
that all of the rights of payment of such principal or interest then due for
payment shall thereupon vest in the insurer. Upon payment by the insurer of any
principal or interest payments with respect to any municipal securities, the
insurer shall succeed to the rights of the Fund with respect to such payment.

     Original Issue Insurance remains in effect as long as the municipal
securities covered thereby remain outstanding and the insurer remains in
business, regardless of whether the Fund ultimately disposes of such municipal
securities. Consequently, Original Issue Insurance may be considered to
represent an element of market value with respect to the municipal securities so
insured, but the exact effect, if any, of this insurance on such market value
cannot be estimated.

     SECONDARY MARKET INSURANCE.  Subsequent to the time of original issuance of
a municipal security, the Fund or a third party may, upon the payment of a
single premium, purchase insurance on such municipal security. Secondary Market
Insurance generally provides the same type of coverage as is provided by
Original Issue Insurance and, as is the case with Original Issue Insurance,
Secondary Market Insurance remains in effect as long as the municipal security
covered thereby remains outstanding and the insurer remains in business,
regardless of whether the Fund ultimately disposes of such municipal security.
All premiums respecting municipal securities covered by Original Issue Insurance
or Secondary Market Insurance are paid in advance by the issuer or other party
obtaining the insurance.

     One of the purposes of acquiring Secondary Market Insurance with respect to
a particular municipal security would be to 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-6


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 as of the date of purchase by the Fund and will not be increased or
decreased for any change in the creditworthiness of such obligation unless such
obligation is in default as to payment of principal or interest, or both. In
such event, the Permanent Insurance premium shall be subject to an increase
predetermined at the date of purchase by the Fund.

     Because each Portfolio Insurance policy will terminate as to municipal
securities sold by the Fund on the date of sale, in which event the insurer will
be liable only for those payments of principal and interest that are then due
and owing (unless Permanent Insurance is obtained by the Fund), the provision
for this insurance will not enhance the marketability of securities held by the
Fund, whether or not the securities are in default or in significant risk of
default. On the other hand, since Original Issue Insurance and Secondary Market
Insurance will remain in effect as long as municipal securities covered thereby
are outstanding, such insurance may enhance the marketability of such securities
even when such securities are in default or in significant risk of default, but
the exact effect, if any, on the marketability cannot be estimated. Accordingly,
the Fund may determine to retain or, alternatively, to sell municipal securities
covered by Original Issue Insurance or Secondary Market Insurance that are in
default or in significant risk of default.

     GENERAL.  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

                                       B-7


municipal securities insured under policies obtained by persons other than the
Fund, the Fund does not pay the premiums for such policies; rather the cost of
such policies may be reflected in a higher purchase price for such municipal
securities. Accordingly, the yield on such municipal securities may be lower
than that on similar uninsured municipal securities. Premiums for a Portfolio
Insurance Policy generally are paid by the Fund monthly, and are adjusted for
purchases and sales of municipal securities covered by the policy during the
month. The yield on the Fund's portfolio is reduced to the extent of the
insurance premiums paid by the Fund which, in turn, will depend upon the
characteristics of the covered municipal securities held by the Fund. In the
event the Fund were to purchase Secondary Market Insurance with respect to any
municipal securities then covered by a Portfolio Insurance policy, the coverage
and the obligation of the Fund to pay monthly premiums under such policy would
cease with such purchase.

     There can be no assurance that insurance of the kind described above will
continue to be available to the Fund. In the event that such insurance is no
longer available or that the cost of such insurance outweighs the benefits to
the Fund in the view of the Board of Trustees, the Board will consider whether
to modify the investment policies of the Fund, which may require the approval of
shareholders. In the event the claims-paying ability rating of an insurer of
municipal securities in the Fund's portfolio were to be lowered from AAA by
Standard and Poor's ("S&P"), Aaa by Moody's Investor Services, Inc. ("Moody's")
or an equivalent rating by another nationally recognized statistical ratings
organization ("NRSRO"), or if the Adviser anticipates such a lowering or
otherwise does not believe an insurer's claims-paying ability merits its
existing triple-A rating, the Fund could seek to obtain additional insurance
from an insurer whose claims-paying ability is rated AAA by S&P, Aaa by Moody's
or an equivalent rating by another NRSRO, or if the Adviser determines that the
cost of obtaining such additional insurance outweigh the benefits, the Fund may
elect not to obtain additional insurance. In making such determination, the
Adviser will consider the cost of the additional insurance, the new
claims-paying ability rating and financial condition of the existing insurer and
the creditworthiness of the issuer or guarantor of the underlying municipal
securities. The Adviser also may determine not to purchase additional insurance
in such circumstances if it believes that the insurer is taking steps which will
cause its triple-A claims paying ability rating to be restored promptly.

     Although the Adviser periodically reviews the financial condition of each
insurer, there can be no assurance that the insurers will be able to honour
their obligations under all circumstances. The Fund cannot predict the
consequences of a state takeover of an insurer's obligations and, in particular,
whether such an insurer (or its state regulatory agency) could or would honour
all of the insurer's contractual obligations including any outstanding insurance
contracts insuring the timely payment of principal and interest on municipal
securities. The Fund cannot predict the impact which such events might have on
the market values of such municipal security. In the event of a default by an
insurer on its obligations with respect to any municipal securities in the
Fund's portfolio, the Fund would look to the issuer or guarantor of the relevant
municipal securities for payments of principal and interest and such issuer or
guarantor may not be rated AAA by S&P, Aaa by Moody's or an equivalent rating by
another NRSRO. Accordingly, the Fund could be exposed to greater risk of
non-payment in such circumstances which could adversely affect the Fund's net
asset value. 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.

"WHEN-ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS

     The Fund may also purchase and sell securities on a "when-issued" and
"delayed delivery" basis. No income accrues to the Fund on securities in
connection with such transactions prior to the date the Fund actually takes
delivery of such securities. These transactions are subject to market
fluctuation; the value of the securities at delivery may be more or less than
their purchase price, and yields generally available on securities
                                       B-8


when delivery occurs may be higher or lower than yields on the 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, cash or liquid securities having an aggregate value equal to the amount
of such purchase commitments until payment is made. The Fund will make
commitments to purchase 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.

PORTFOLIO TURNOVER

     The Fund's 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.

ILLIQUID SECURITIES

     The Fund may invest up to 15% of its net assets in illiquid securities,
which includes securities that are not readily marketable, repurchase agreements
which have a maturity of longer than seven days and generally includes
securities that are restricted from sale to the public without registration
under the Securities Act of 1933, as amended (the "1933 Act"). The sale of such
securities often requires more time and results in higher brokerage charges or
dealer discounts and other selling expenses than does the sale of liquid
securities trading on national securities exchanges or in the over-the-counter
markets. Restricted securities are often purchased at a discount from the market
price of unrestricted securities of the same issuer reflecting the fact that
such securities may not be readily marketable without some time delay.
Investments in securities for which market quotations are not readily available
are valued at their fair value as determined in good faith by the Adviser in
accordance with procedures approved by the Fund's Board of Trustees. Ordinarily,
the Fund would invest in restricted securities only when it receives the
issuer's commitment to register the securities without expense to the Fund.
However, registration and underwriting expenses (which typically range from 7%
to 15% of the gross proceeds of the securities sold) may be paid by the Fund.
Restricted securities which can be offered and sold to qualified institutional
buyers under Rule 144A under the 1933 Act ("144A Securities") and are determined
to be liquid under guidelines adopted by and subject to the supervision of the
Fund's Board of Trustees are not subject to the limitation on illiquid
securities. Such 144A Securities are subject to monitoring and may become
illiquid to the extent qualified institutional buyers become, for a time,
uninterested in purchasing such securities. Factors used to determine whether
144A Securities are liquid include, among other things, a security's trading
history, the availability of reliable pricing information, the number of dealers
making quotes or making a market in such security and the number of potential
purchasers in the market for such security. For purposes hereof, investments by
the Fund in securities of other investment companies will not be considered
investments in restricted securities to the extent permitted by (i) the 1940
Act, as amended from time to time, (ii) the rules and regulations promulgated by
the SEC under the 1940 Act, as amended from time to time, or (iii) an exemption
or other relief (such as "no action" letters issued by the staff of the SEC
interpreting or providing guidance on the 1940 Act or regulations thereunder)
from the provisions of the 1940 Act, as amended from time to time.

                             STRATEGIC TRANSACTIONS

     The Fund may, but is not required to, use various Strategic Transactions
(as defined in the Prospectus) to earn income, facilitate portfolio management
and mitigate risks. Techniques and instruments may change over time as new
instruments and strategies are developed or regulatory changes occur. Although
the Adviser seeks

                                       B-9


to use such transactions to further the Fund's investment objective, no
assurance can be given that the use of these transactions will achieve this
result.

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 futures
contracts, index or other instrument might be intended to protect the Fund
against an increase in the price of the underlying instrument that it intends to
purchase in the future by fixing the price at which it may purchase such
instrument. An American style put or call option may be exercised at any time
during the option period while a European style put or call option may be
exercised only upon expiration or during a fixed period prior thereto. The Fund
is authorized to purchase and sell exchange listed options and over-the-counter
options ("OTC options"). Exchange listed options are issued by a regulated
intermediary such as the Options Clearing Corporation ("OCC"), which guarantees
the performance of the obligations of the parties to such options. The
discussion below uses the OCC as a paradigm, but is also applicable to other
financial intermediaries.

     With certain exceptions, OCC issued and exchange listed options generally
settle by physical delivery of the underlying security or currency, although in
the future cash settlement may become available. Index options and Eurodollar
instruments are cash settled for the net amount, if any, by which the option is
"in-the-money" (i.e., where the value of the underlying instrument exceeds, in
the case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed options are closed by entering into
offsetting purchase or sale transactions that do not result in ownership of the
new option.

     The Fund's ability to close out its position as a purchaser or seller of an
OCC or exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. Among the possible reasons for the absence of a
liquid option market on an exchange are: (i) insufficient trading interest in
certain options; (ii) restrictions on transactions imposed by an exchange; (iii)
trading halts, suspensions or other restrictions imposed with respect to
particular classes or series of options or underlying securities including
reaching daily price limits; (iv) interruption of the normal operations of the
OCC or an exchange; (v) inadequacy of the facilities of an exchange or OCC to
handle current trading volume; or (vi) a decision by one or more exchanges to
discontinue the trading of options (or a particular class or series of options),
in which event the relevant market for that option on that exchange would cease
to exist, although outstanding options on that exchange would generally continue
to be exercisable in accordance with their terms.

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

     OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC option,
                                       B-10


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 enter into OTC options that have a buy-back provision permitting the Fund
to require the Counterparty to close the option at a formula price within seven
days. The Fund expects generally to enter into OTC options that have cash
settlement provisions, although it is not required to do so.

     Unless the parties provide for it, there is no central clearing or guaranty
function in an OTC option. As a result, if the Counterparty fails to make or
take delivery of the security, or other instrument underlying an OTC option it
has entered into with the Fund or fails to make a cash settlement payment due in
accordance with the terms of that option, the Fund will lose any premium it paid
for the option as well as any anticipated benefit of the transaction.
Accordingly, the Adviser must assess the creditworthiness of each such
Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be satisfied.
The Fund will engage in OTC option transactions only with United States
government securities dealers recognized by the Federal Reserve Bank of New York
as "primary dealers", or broker-dealers, domestic or foreign banks or other
financial institutions which have received (or the guarantors of the obligation
of which have received) a short-term credit rating of "A-1" from S&P or "P-1"
from Moody's or an equivalent rating from any other NRSRO. The staff of the SEC
currently takes the position that, in general, OTC options on securities (other
than U.S. government securities) purchased by the Fund, and portfolio securities
"covering" the amount of the Fund's obligation pursuant to an OTC option sold by
it (the cost of the sell-back plus the in-the-money amount, if any) are
illiquid, and are subject to the Fund's limitation on illiquid securities
described herein.

     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, corporate debt securities that are traded on securities exchanges
and in the over-the-counter markets and related futures contracts. All calls
sold by the Fund must be "covered" (i.e., the Fund must own the securities or
futures contract subject to the call) or must meet the asset segregation
requirements described below as long as the call is outstanding. Even though the
Fund will receive the option premium to help protect it against loss, a call
sold by the Fund exposes the Fund during the term of the option to possible loss
of opportunity to realize appreciation in the market price of the underlying
security or instrument and may require the Fund to hold a security or instrument
which it might otherwise have sold. In the event of exercise of a call option
sold by the Fund with respect to securities not owned by the Fund, the Fund may
be required to acquire the underlying security at a disadvantageous price to
satisfy its obligation with respect to the call option.

     The Fund may purchase and sell put options on securities including U.S.
Treasury and agency securities, municipal obligations, mortgage-backed
securities and corporate debt securities (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 contracts and options on futures contracts. 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.

FUTURES CONTRACTS

     The Fund may enter into financial futures contracts or purchase or sell put
and call options on futures contracts as a hedge against anticipated interest
rate or fixed-income market changes, for duration management and for risk
management purposes. Futures contracts 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
contracts and Eurodollar instruments, the net cash amount). The sale of a

                                       B-11


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 contracts 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 contracts and options on futures
contracts 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 on a
futures contract 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 contracts 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
contract position just as it would for any position. Futures contracts and
options on futures contracts 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 an option on a futures
contract (except for closing transactions) for other than bona fide hedging
purposes if, immediately thereafter, the sum of the amount of its initial margin
and premiums on open futures contracts and options on futures contracts 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 on
futures contracts 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 contracts transactions and multiple interest rate
transactions and any combination of futures contracts, 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
                                       B-12


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. A
large number of banks and investment banking firms act 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 cash and liquid securities to the extent Fund
obligations are not otherwise "covered" through ownership of the underlying
security, financial instrument or currency. In general, either the full amount
of any obligation by the Fund to pay or deliver securities or assets must be
covered at all times by the securities, instruments or currency required to be
delivered, or, subject to any regulatory restrictions, an amount of cash or
liquid securities at least equal to the current amount of the obligation must be
segregated. The segregated assets cannot be sold or transferred unless
equivalent assets are substituted in their place or it is no longer necessary to
segregate. 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 cash and
liquid securities sufficient to purchase and deliver the securities if the call
is exercised. A call option sold by the Fund on an index will require the Fund
to own portfolio securities which correlate with the index or to segregate cash
and liquid securities equal to the excess of the index value over the exercise
price on a current basis. A put option written by the Fund requires the Fund to
segregate cash and liquid securities equal to the exercise price.

                                       B-13


     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 cash and liquid
securities 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 and liquid securities 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 cash and liquid securities 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 on a futures contract, the
Fund must deposit initial margin and possible daily variation margin in addition
to segregating cash and liquid securities 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.

     With respect to swaps, the Fund will accrue the net amount of the excess,
if any, of its obligations over its entitlements with respect to each swap on a
daily basis and will segregate an amount of cash or liquid securities having a
value equal to the accrued excess. Caps, floors and collars require segregation
of cash and liquid securities 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 cash and
liquid securities, 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 cash and liquid
securities if the Fund held a futures contract or forward contract, it could
purchase a put option on the same futures contract 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, cash and
liquid securities equal to any remaining obligation would need to be segregated.

     The Fund's activities involving Strategic Transactions may be limited by
the requirements of the Code for qualification as a regulated investment
company.

                            INVESTMENT RESTRICTIONS

     The Fund has adopted the following fundamental investment restrictions
which may not be changed without shareholder approval by the vote of a majority
of its outstanding voting securities, which is defined by the 1940 Act as the
lesser of (i) 67% or more of the Fund's voting securities present at a meeting,
if the holders of more than 50% of the Fund's outstanding voting securities are
present or represented by proxy; or (ii) more than 50% of the Fund's outstanding
voting securities. The percentage limitations contained in the restrictions and
policies set forth herein apply at the time of purchase of securities. With
respect to the limitations on illiquid securities and borrowings, the percentage
limitations apply at the time of purchase and on an ongoing basis. These
restrictions provide that the Fund shall not:

     1. Purchase any securities (other than tax exempt obligations guaranteed by
        the United States government or by its agencies or instrumentalities),
        if as a result more than 5% of the Fund's total assets (taken at current
        value) would then be invested in securities of a single issuer or if as
        a result the Fund would hold more than 10% of the outstanding voting
        securities of any single issuer, except that the Fund may purchase
        securities of other investment companies to the extent permitted by (i)
        the 1940 Act, as amended from time to time, (ii) the rules and
        regulations promulgated by the

                                       B-14


        SEC under the 1940 Act, as amended from time to time, or (iii) an
        exemption or other relief from the provisions of the 1940 Act, as
        amended from time to time.

     2. Invest more than 25% of its assets in a single industry; however, 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, and except that the Fund may purchase securities
        of other investment companies to the extent permitted by (i) the 1940
        Act, as amended from time to time, (ii) the rules and regulations
        promulgated by the SEC under the 1940 Act, as amended from time to time,
        or (iii) an exemption or other relief from the provisions of the 1940
        Act, as amended from time to time.

     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 maintenance
        margin in connection with interest rate or other financial futures
        contracts or index contracts or options on futures contracts 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 contracts or index contracts or options on futures
        contracts, except as hedging transactions in accordance with the
        requirements of the SEC and the Commodity Futures Trading Commission.

     7. Act as an underwriter of securities, except to the extent the Fund may
        be deemed to be an underwriter in connection with the sale of securities
        held in its portfolio.

     8. Make investments for the purpose of exercising control or participation
        in management, except that the Fund may purchase securities of other
        investment companies to the extent permitted by (i) the 1940 Act, as
        amended from time to time, (ii) the rules and regulations promulgated by

         DESCRIPTION OF INSURANCE COMPANY CLAIMS PAYING ABILITY RATINGS

RATINGS OF INSURANCE COMPANY CLAIMS-PAYING ABILITY

     The claims-paying ability of insurance companies is rated by S&P and
Moody's. Descriptions of these ratings are set forth below:

DESCRIPTION OF S&P'S RATINGS OF INSURANCE COMPANY CLAIMS-PAYING ABILITY

     A S&P Insurer Financial Strength Rating is a current opinion of the
financial security characteristics of an insurance organization with respect to
its ability to pay under its insurance policies and contracts in accordance with
their terms. Insurer Financial Strength Ratings are also assigned to health
maintenance organizations and similar health plans with respect to their ability
to pay under their policies and contracts in accordance with their terms.

     This opinion is not specific to any particular policy or contract, nor does
it address the suitability of a particular policy or contract for a specific
purpose or purchaser. Furthermore, the opinion does not take into account
deductibles, surrender or cancellation penalties, timeliness of payment, nor the
likelihood of the use of a defense such as fraud to deny claims. For
organizations with cross-border or multinational operations, including those
conducted by subsidiaries or branch offices, the ratings do not take into
account potential that may exist for foreign exchange restrictions to prevent
financial obligations from being met.

     Insurer Financial Strength Ratings are based on information furnished by
rated organizations 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. Ratings may be changed, suspended, or
withdrawn as a result of changes in, or unavailability of such information or
based on other circumstances.

     Insurer Financial Strength Ratings do not refer to an organization's
ability to meet nonpolicy (i.e., debt) obligations. Assignment of ratings to
debt issued by insurers or to debt issues that are fully or partially supported
by insurance policies, contracts, or guarantees is a separate process from the
determination of Insurer Financial Strength Ratings, and follows procedures
consistent with issue credit rating definitions and practices. Insurer Financial
Strength Ratings are not a recommendation to purchase or discontinue any policy
or contract issued by an insurer or to buy, hold, or sell any security issued by
an insurer. A rating is not a guaranty of an insurer's financial strength or
security.

     An insurer rated "BBB" or higher is regarded as having financial security
characteristics that outweigh any vulnerabilities, and is highly likely to have
the ability to meet financial commitments.

     AAA. An insurer rated "AAA" has EXTREMELY STRONG financial security
characteristics. "AAA" is the highest Insurer Financial Strength Rating assigned
by S&P.

     AA. An insurer rated "AA" has VERY STRONG financial security
characteristics, differing only slightly from those rated higher.

     A. An insurer rated "A" has STRONG financial security characteristics, but
is somewhat more likely to be affected by adverse business conditions than are
insurers with higher ratings.

     BBB. An insurer rated "BBB" has GOOD financial security characteristics,
but is more likely to be affected by adverse business conditions than are higher
rated insurers. An insurer rated "BB" or lower is regarded as having vulnerable
characteristics that may outweigh its strengths. "BB" indicates the least degree
of vulnerability within the range; "CC" the highest.

     Ratings from "AA" to "CCC" may be modified by the addition of a plus (+) or
minus (-) signs following ratings show relative standing within the major rating
categories. CreditWatch highlights the potential direction of a rating, focusing
on identifiable events and short-term trends that cause ratings to be placed
under special surveillance by S&P. The events may include mergers,
recapitalizations, voter referenda, regulatory actions, or anticipated operating
developments. Ratings appear on CreditWatch when such an event or a deviation
from an expected trend occurs and additional information is needed to evaluate
the rating. A

                                       B-16


listing, however, does not mean a rating change is inevitable, and whenever
possible, a range of alternative ratings will be shown.

     Credit Watch is not intended to include all ratings under review, and
rating changes may occur without the ratings having first appeared on
CreditWatch. The "positive" designation means that a rating may be raised;
"negative" means that a rating may be lowered; "developing" means that a rating
may be raised, lowered or affirmed.

     "pi" Ratings, denoted with a "pi" subscript, are Insurer Financial Strength
Ratings based on an analysis of published financial information and additional
information in the public domain. They do not reflect in-depth meetings with an
insurer's management and are therefore based on less comprehensive information
than ratings without a "pi" subscript. "pi" ratings are reviewed annually based
on a new year's financial statements, but may be reviewed on an interim basis if
a major event that may affect an insurer's financial security occurs. Ratings
with a "pi" subscript are not subject to potential Credit Watch listings and are
not modified with "+" or "-" designations.

DESCRIPTION OF MOODY'S RATINGS OF INSURANCE COMPANY CLAIMS-PAYING ABILITY

     Moody's Insurance Financial Strength Ratings are opinions of the ability of
insurance companies to repay punctually senior policyholder claims and
obligations. Specific obligations are considered unrated unless they are
individually rated because the standing of a particular insurance obligation
would depend on an assessment of its relative standing under those laws
governing both the obligation and the insurance company.

     It is important to note that Moody's makes no representation that rated
insurance company obligations are exempt from registration under the U.S.
Securities Act of 1933 or issued in conformity with any other applicable law or
regulation. Nor does Moody's represent that any specific insurance company
obligation is legally enforceable or a valid senior obligation of a rated
issuer.

     Insurance Financial Strength Ratings shown in connection with
property/casualty groups represent the ratings of individual companies within
those groups, as displayed in Moody's insurance industry ratings list. The
rating of an individual property/casualty company may be based on the benefit of
its participation in an intercompany pooling agreement. Pooling agreements may
or may not provide for continuation of in-force policyholder obligations by pool
members in the event that the property/casualty insurer is sold to a third party
or otherwise removed from the pooling agreement.

     Moody's assumes in these ratings that the pooling agreement will not be
modified by the members of the pool to reduce the benefits of pool
participating, and that the insurer will remain in the pool. Moody's makes no
representation or warranty that such pooling agreement will not be modified over
time, nor does Moody's opine on the probability that the rated entity may be
sold or otherwise removed from the pooling agreement.

     Moody's rating symbols for Insurance Financial Strength Ratings are
identical to those used to show the credit quality of bonds. These rating
gradations provide investors with a simple system to measure an insurance
company's ability to meet its senior policyholder claims and obligations.

     Rating gradations are broken down into nine distinct symbols, each symbol
representing a group of ratings in which the quality characteristics are broadly
the same. These symbols, which comprise two distinct rating groups of strong and
weak companies, range from those used to designate the greatest financial
strength (i.e., highest investment quality) to those denoting the least
financial strength (i.e., lowest investment quality).

     Numeric modifiers are used to refer to the ranking within the group -- with
1 being the highest and 3 being the lowest. However, the financial strength of
companies within a generic rating symbol (Aa, for example) is broadly the same.

     AAA. Insurance companies rated Aaa offer exceptional financial security.
While the financial strength of these companies is likely to change, such
changes as can be visualized are most unlikely to impair their fundamentally
strong position.

                                       B-17


     AA. Insurance companies rated Aa offer excellent financial security.
Together with the Aaa group, they constitute what are generally known as
high-grade companies. They are rated lower than Aaa companies because long-term
risks appear somewhat larger.

     A. Insurance companies rated A offer good financial security. However,
elements may be present which suggest a susceptibility to impairment sometime in
the future.

     BAA. Insurance companies rated Baa offer adequate financial security.
However, certain protective elements may be lacking or may be characteristically
unreliable over any great length of time.

</Table>

     Each trustee/director holds the same position with each of the funds in the
Fund Complex. As of the date of this Statement of Additional Information, there
are 61 operating funds in the Fund Complex. Each trustee/director who is not an
affiliated person of Van Kampen Investments, the Advisers or the Distributor
(each a "Non-Affiliated Trustee") is compensated by an annual retainer and
meeting fees for services to the funds in the Fund Complex. Each fund in the
Fund Complex provides a deferred compensation plan to its Non-Affiliated
Trustees that allows trustees/directors to defer receipt of their compensation
and earn a return on such deferred amounts. Deferring compensation has the
economic effect as if the Non-Affiliated Trustee reinvested his or her
compensation into the funds. Each fund in the Fund Complex provides a retirement
plan to its Non-Affiliated Trustees that provides Non-Affiliated Trustees with
compensation after retirement, provided that certain eligibility requirements
are met as more fully described below.

     The compensation of each Non-Affiliated Trustee includes an annual retainer
in an amount equal to $50,000 per calendar year, due in four quarterly
installments on the first business day of each quarter. Payment of the annual
retainer is allocated among the funds in the Fund Complex on the basis of the
relative net assets of each fund as of the last business day of the preceding
calendar quarter. The compensation of each Non-Affiliated Trustee includes a per
meeting fee from each fund in the Fund Complex in the amount of $200 per
quarterly or special meeting attended by the Non-Affiliated Trustee, due on the
date of the meeting, plus reasonable expenses incurred by the Non-Affiliated
Trustee in connection with his or her services as a trustee/ director, provided
that no compensation will be paid in connection with certain telephonic special
meetings.

     Under the deferred compensation plan, each Non-Affiliated Trustee generally
can elect to defer receipt of all or a portion of the compensation earned by
such Non-Affiliated Trustee until retirement. Amounts deferred are retained by
the Fund and earn a rate of return determined by reference to the return on the
common shares of such Fund or other funds in the Fund Complex as selected by the
respective Non-Affiliated Trustee, with the same economic effect as if such
Non-Affiliated Trustee had invested in one or more funds in the Fund Complex. To
the extent permitted by the 1940 Act, the Fund may invest in securities of those
funds selected

                                       B-23


by the Non-Affiliated Trustees in order to match the deferred compensation
obligation. The deferred compensation plan is not funded and obligations
thereunder represent general unsecured claims against the general assets of the
Fund.

     Under the retirement plan, a Non-Affiliated Trustee who is receiving
compensation from such Fund prior to such Non-Affiliated Trustee's retirement,
has at least 10 years of service (including years of service prior to adoption
of the retirement plan) and retires at or after attaining the age of 60, is
eligible to receive a retirement benefit equal to $2,500 per year for each of
the ten years following such retirement from such Fund. Non-Affiliated Trustees
retiring prior to the age of 60 or with fewer than 10 years but more than 5
years of service may receive reduced retirement benefits from such Fund. Each
trustee/director has served as a member of the Board of Trustees of the Fund
since he or she was first appointed or elected in the year set forth below. The
retirement plan contains a Fund Complex retirement benefit cap of $60,000 per
year.

     Additional information regarding compensation and benefits for trustees is
set forth below for the periods described in the notes accompanying the table.

(1) Trustees not eligible for compensation are not included in the Compensation
    Table. Fernando Sisto retired as a member of the Board of Trustees for the
    Fund and other funds in the Fund Complex on December 31, 2000.

(2) The amounts shown in this column represent the aggregate compensation before
    deferral with respect to the Trust's fiscal year ended September 30, 2001.
    The detail of aggregate compensation before deferral for each series,
    including the Fund, is shown in Table A below. The detail of amounts
    deferred for each series, including the Fund, is shown in Table B below.
    Amounts deferred are retained by the Fund and earn a rate of return
    determined by reference to either the return on the common shares of the
    Fund or other funds in the Fund Complex as selected by the respective
    Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, each fund may invest in
    securities of those funds selected by the Non-Affiliated Trustees in order
    to match the deferred compensation obligation. The detail of cumulative
    deferred compensation (including interest) owed to trustees, including
    former trustees, by each series, including the Fund, is shown in Table C
    below. The deferred compensation plan is described above the Compensation
    Table.

(3) The amounts shown in this column represent the sum of the retirement
    benefits accrued by the operating investment companies in the Fund Complex
    for each of the trustees for the funds' respective fiscal years ended in
    2001. The retirement plan is described above the Compensation Table.

(4) For each trustee, this is the sum of the estimated maximum annual benefits
    payable by the funds in the Fund Complex for each year of the 10-year period
    commencing in the year of such trustee's anticipated retirement. The
    retirement plan is described above the Compensation Table. Each
    Non-Affiliated Trustee of the Board of Trustees has served as a member of
    the Board of Trustees since he or she was first appointed or elected in the
    year set forth in Table D below.

                                       B-24


(5) The amounts shown in this column represent the aggregate compensation paid
    by all of the funds in the Fund Complex as of December 31, 2001 before
    deferral by the trustees under the deferred compensation plan. Because the
    funds in the Fund Complex have different fiscal year ends, the amounts shown
    in this column are presented on a calendar year basis. Certain trustees
    deferred all or a portion of their aggregate compensation from the Fund
    Complex during the calendar year ended December 31, 2001. The deferred
    compensation earns a rate of return determined by reference to the return on
    the shares of the funds in the Fund Complex as selected by the respective
    Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, the Fund may invest in
    securities of those investment companies selected by the Non-Affiliated
    Trustees in order to match the deferred compensation obligation. The
    Advisers and their affiliates also serve as investment adviser for other
    investment companies; however, with the exception of Mr. Whalen, the
    Non-Affiliated Trustees were not trustees of such investment companies.
    Combining the Fund Complex with other investment companies advised by the
    Advisers and their affiliates, Mr. Whalen earned Total Compensation of
    $276,650 during the calendar year ended December 31, 2001.

                                                                         TABLE A

     The Fund, the Adviser and the Distributor have adopted a Code of Ethics
(the "Code of Ethics") that sets forth general and specific standards relating
to the securities trading activities of their employees. The Code of Ethics does
not prohibit employees from acquiring securities that may be purchased or held
by the Fund, but is intended to ensure that all employees conduct their personal
transactions in a manner that does not interfere with the portfolio transactions
of the Fund or other Van Kampen funds, or that such employees take unfair
advantage of their relationship with the Fund. Among other things, the Code of
Ethics prohibits certain types of transactions absent prior approval, imposes
various trading restrictions (such as time periods during which personal
transactions may or may not be made) and requires quarterly reporting of
securities transactions and other reporting matters. All reportable securities
transactions and other required reports are to be reviewed by appropriate
personnel for compliance with the Code of Ethics. Additional restrictions apply
to portfolio managers, traders, research analysts and others who may have access
to nonpublic information about the trading activities of the Fund or other Van
Kampen funds or who otherwise are involved in the investment advisory process.
Exceptions to these and other provisions of the Code of Ethics may be granted in
particular circumstances after review by appropriate personnel.

     As of January 8, 2002, the trustees and officers of the Fund as a group
owned less than 1% of the shares of the Fund.

                         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 the Fund's assets, including the placing of
orders for the purchase and sale of portfolio securities. The Adviser obtains
and evaluates economic, statistical and financial information to formulate
strategy and implement the Fund's investment objective. The Adviser also
furnishes offices, necessary facilities and equipment, provides administrative
services to the Fund, renders periodic reports to the Fund's Board of Trustees,
and permits its officers and employees to serve without compensation as trustees
of the Trust or officers of the Fund if elected to such positions. The Fund,
however, bears the costs of its day-to-day operations, including service fees,

                                       B-26


distribution fees, custodian fees, legal and independent accountant fees, the
costs of reports and proxies to shareholders, compensation of trustees of the
Fund (other than those who are affiliated persons of the Adviser, Distributor or
Van Kampen Investments) and all other ordinary business expenses not
specifically assumed by the Adviser. The Advisory Agreement also provides that
the Adviser shall not be liable to the Fund for any error of judgment or of law,
or for any loss suffered by the Fund in connection with the matters to which the
Advisory 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 Advisory Agreement.

     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 any jurisdiction in which the Fund's shares are qualified for
offer and sale (excluding any expenses permitted to be excluded from the
computation under applicable law or regulation), 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 Fund
monthly an amount sufficient to make up the deficiency, subject to readjustment
during the fiscal year.

     The Advisory Agreement may be continued from year to year if specifically
approved at least annually (a)(i) by the Fund's Board of Trustees or (ii) by a
vote of a majority of the Fund's outstanding voting securities and (b) by a 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.

     During the fiscal years ended September 30, 2001, 2000 and 1999, the
Adviser received approximately $5,919,500, $5,894,000 and $6,729,700,
respectively, in advisory fees from the Fund.

                                OTHER AGREEMENTS

     ACCOUNTING SERVICES AGREEMENT.  The Fund has entered into an accounting
services agreement pursuant to which Advisory Corp. provides accounting services
to the Fund 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 pays all costs and expenses related to such services,
including all salary and related benefits of accounting personnel, as well as
the overhead and expenses of office space and the equipment necessary to render
such services. The Fund shares together with the other Van Kampen funds in the
cost of providing such services with 25% of such costs shared proportionately
based on the respective number of classes of securities issued per fund and the
remaining 75% of such costs based proportionately on the respective net assets
per fund.

     During the fiscal years ended September 30, 2001, 2000 and 1999, Advisory
Corp. received approximately $96,900, $71,800 and $310,000, respectively, in
accounting services fees from the Fund.

     LEGAL SERVICES AGREEMENT.  The Fund and certain other Van Kampen funds have
entered into legal services agreements pursuant to which Van Kampen Investments
provides legal services, including without limitation: accurate maintenance of
each fund's minute books and records, preparation and oversight of each fund's
regulatory reports and other information provided to shareholders, as well as
responding to day-to-day legal issues on behalf of the funds. Payment by the
funds for such services is made on a cost basis for the salary and
salary-related benefits, including but not limited to bonuses, group insurance
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 Investments. Of the total costs for legal
services provided to funds, 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.

     During the fiscal years ended September 30, 2001, 2000 and 1999, Van Kampen
Investments received approximately $59,000, $27,600 and $26,600, respectively,
in legal services fees from the Fund.

                                       B-27


                            DISTRIBUTION AND SERVICE

     The Distributor acts as the principal underwriter of the Fund's shares
pursuant to a written agreement (the "Distribution and Service Agreement"). The
Distributor has the exclusive right to distribute shares of the Fund through
authorized dealers on a continuous basis. 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 certain other costs including the cost of
supplemental sales literature and advertising. The Distribution and Service
Agreement is renewable from year to year if approved (a)(i) by the Fund's Board
of Trustees or (ii) by a vote of a majority of the Fund's outstanding voting
securities and (b) by a vote of a majority of Trustees who are not parties to
the Distribution and Service Agreement or interested persons of any party, by
votes cast in person at a meeting called for such purpose. The Distribution and
Service Agreement provides that it will terminate if assigned, and that it may
be terminated without penalty by either party on 90 days' written notice. Total
underwriting commissions on the sale of shares of the Fund for the last three
fiscal years are shown in the chart below.

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

* No sales charge is payable at the time of purchase on investments of $1
  million or more, although the Fund may impose a contingent deferred sales
  charge of 1.00% on certain redemptions made within one year of the purchase. A
  commission or transaction fee will be paid by the Distributor at the time of
  purchase directly out of the Distributor's assets (and not out of the Fund's
  assets) to authorized dealers who initiate and are responsible for purchases
  of $1 million or more computed on a percentage of the dollar value of such
  shares sold as follows: 1.00% on sales to $2 million, plus 0.80% on the next
  $1 million and 0.50% on the excess over $3 million. For single purchases of
  $20 million or more by an individual retail investor, the Distributor will
  pay, at the time of purchase and directly out of the Distributor's assets (and
  not out of the Fund's assets), a commission or transaction fee of 1.00% to
  authorized dealers who initiate and are responsible for such purchases. The
  commission or transaction fee of 1.00% will be computed on a percentage of the
  dollar value of such shares sold.

     With respect to sales of Class B Shares and Class C Shares of the Fund, a
commission or transaction fee generally will be paid by the Distributor at the
time of purchase directly out of the Distributor's assets (and not out of the
Fund's assets) to authorized dealers who initiate and are responsible for such
purchases computed based on a percentage of the dollar value of such shares sold
of 4.00% on Class B Shares and 1.00% on Class C Shares.

                                       B-28


     Proceeds from any contingent deferred sales charge and any distribution
fees on Class B Shares and Class C Shares of the Fund are paid to the
Distributor and are used by the Distributor to defray its distribution related
expenses in connection with the sale of the Fund's shares, such as the payment
to authorized dealers for selling such shares. With respect to Class C Shares,
the authorized dealers generally are paid the ongoing commission and transaction
fees of up to 0.75% of the average daily net assets of the Fund's Class C Shares
annually commencing in the second year after purchase.

     In addition to reallowances or commissions described above, the Distributor
may from time to time implement programs under which an authorized dealer's
sales force may be eligible to win nominal awards for certain sales efforts or
under which the Distributor will reallow to any authorized dealer 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 authorized dealer at the public offering price during such programs.
Also, the Distributor in its discretion may from time to time, pursuant to
objective criteria established by the Distributor, pay fees to, and sponsor
business seminars for, qualifying authorized dealers for certain services or
activities which are primarily intended to result in sales of shares of the Fund
or other Van Kampen funds. Fees may include payment for travel expenses,
including lodging, incurred in connection with trips taken by invited registered
representatives for meetings or seminars of a business nature. In some instances
additional compensation or promotional incentives may be offered to brokers,
dealers or financial intermediaries that have sold or may sell significant
amounts of shares during specified periods of time. The Distributor may provide
additional compensation to Edward D. Jones & Co. or an affiliate thereof based
on a combination of its quarterly sales of shares of the Fund and other Van
Kampen funds and increases in net assets of the Fund and other Van Kampen funds
over specified thresholds. All of the foregoing payments are made by the
Distributor out of its own assets. Such fees paid for such services and
activities with respect to the Fund will not exceed in the aggregate 1.25% of
the average total daily net assets of the Fund on an annual basis. These
programs will not change the price an investor will pay for shares or the amount
that a Fund will receive from such sale.

     The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each of its Class A Shares, Class B Shares and Class C Shares
pursuant to Rule 12b-1 under the 1940 Act. The Fund also adopted a service plan
(the "Service Plan") with respect to each of its Class A Shares, Class B Shares
and Class C Shares. The Distribution Plan and the Service Plan sometimes are
referred to herein as the "Plans." The Plans provide that the Fund may spend a
portion of the Fund's average daily net assets attributable to each such class
of shares in connection with distribution of the respective class of shares and
in connection with the provision of ongoing services to shareholders of such
class, respectively. The Distribution Plan and the Service Plan are being
implemented through the Distribution and Service Agreement with the Distributor
of each such 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."

     Certain financial intermediaries may be prohibited under law from providing
certain underwriting or distribution services. If a financial intermediary was
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 financial intermediary would result in any material adverse consequences
to the Fund.

     The Distributor must submit quarterly reports to the Board of Trustees of
the Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Distribution Plan and the purposes for which
such expenditures were made, together with such other information as from time
to time is reasonably requested by the Trustees. The Plans provide that they
will continue in full force and effect from
                                       B-29


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 any 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 any 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 Class A Shares in any given year in which the Plans are in effect, the
Plans generally provide for the Fund to pay the Distributor the lesser of (i)
the amount of the Distributor's actual expenses incurred during such year less
any deferred sales charges (if any) it received during such year (the "actual
net expenses") or (ii) the distribution and service fees at the rates specified
in the Prospectus (the "plan fees"). Therefore, to the extent the Distributor's
actual net expenses in a given year are less than the plan fees for such year,
the Fund only pays the actual net expenses. Alternatively, to the extent the
Distributor's actual net expenses in a given year exceed the plan fees for such
year, the Fund only pays the plan fees for such year. For Class A Shares, there
is no carryover of any unreimbursed actual net expenses to succeeding years.

     The Plans for Class B Shares and Class C Shares are similar to the Plans
for Class A Shares, except that any actual net expenses which exceed plan fees
for a given year are carried forward and are eligible for payment in future
years by the Fund so long as the Plans remain in effect. Thus, for each of the
Class B Shares and Class C Shares, in any given year in which the Plans are in
effect, the Plans generally provide for the Fund to pay the Distributor the
lesser of (i) the applicable amount of the Distributor's actual net expenses
incurred during such year for such class of shares plus any actual net expenses
from prior years that are still unpaid by the Fund for such class of shares or
(ii) the applicable plan fees for such class of shares. Except as may be
mandated by applicable law, the Fund does not impose any limit with respect to
the number of years into the future that such unreimbursed actual net expenses
may be carried forward (on a Fund level basis). These unreimbursed actual net
expenses may or may not be recovered through plan fees or contingent deferred
sales charges in future years.

     Because of fluctuations in net asset value, the plan fees with respect to a
particular Class B Share or Class C Share may be greater or less than the amount
of the initial commission (including carrying cost) paid by the Distributor with
respect to such share. In such circumstances, a shareholder of a share may be
deemed to incur expenses attributable to other shareholders of such class. As of
September 30, 2001, there were $558,074 and $38,325 of unreimbursed
distribution-related expenses with respect to Class B Shares and Class C Shares,
respectively, representing 1.14% and .34% of the Fund's net assets attributable
to Class B Shares and Class C Shares, respectively. If the Plans are 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 shares to defray distribution-related expenses
attributable to any other class of shares.

     For the fiscal year ended September 30, 2001, the Fund's aggregate expenses
paid under the Plans for Class A Shares were $2,676,195 or 0.25% of the Class A
Shares' average daily net assets. Such expenses were paid to reimburse the
Distributor for payments made to financial intermediaries for servicing Class A
shareholders and for administering the Class A Share Plans. For the fiscal year
ended September 30, 2001, the Fund's aggregate expenses paid under the Plans for
Class B Shares were $448,143 or 1.00% of the Class B Shares' average daily net
assets. Such expenses were paid to reimburse the Distributor for the following
payments: $336,846 for commissions and transaction fees paid to financial
intermediaries in respect of sales of Class B Shares of the Fund and $111,297
for fees paid to financial intermediaries for servicing Class B shareholders and
administering the Class B Share Plans. For the fiscal year ended September 30,
2001, the

                                       B-30


Fund's aggregate expenses paid under the Plans for Class C Shares were $73,844
or 1.00% of the Class C Shares' average daily net assets. Such expenses were
paid to reimburse the Distributor for the following payments: $34,075 for
commissions and transaction fees paid to financial intermediaries in respect of
sales of Class C Shares of the Fund and $39,769 for fees paid to financial
intermediaries for servicing Class C shareholders and administering the Class C
Share Plans.

     From time to time, the Distributor may enter into agreements with
broker-dealers to offer the Fund through retirement plan alliance programs that
offer multiple fund families. These programs may have special investment
minimums and operational requirements. For more information, trustees and other
fiduciaries should contact the Distributor.

                                 TRANSFER AGENT

     The Fund's transfer agent, shareholder service agent and dividend
disbursing agent is Van Kampen Investor Services Inc. The transfer agency prices
are determined through negotiations with the Fund's Board of Trustees and are
based on competitive benchmarks.

                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 on such transactions. While
the Adviser will be primarily responsible for the placement of the Fund's
portfolio business, the policies and practices in this regard will at all times
be subject to review by the Board of Trustees of the Fund.

     As most transactions made by the Fund are principal transactions at net
prices, the Fund generally incurs little or no brokerage costs. The portfolio
securities in which the Fund invests are normally purchased directly from the
issuer or in the over-the-counter market 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 a spread or markup to the dealer
between the bid and asked price. Sales to dealers are effected at bid prices.
The Fund may also purchase certain money market instruments directly from an
issuer, in which case no commissions or discounts are paid, or may purchase and
sell listed securities on an exchange, which are effected through brokers who
charge a commission for their services.

     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 prices and any brokerage commissions
on such transactions, the Adviser considers the firm's reliability, integrity
and financial condition and the firm's execution capability, the size and
breadth of the market for the security, the size of and difficulty in executing
the order, and the best net price. There are many instances when, in the
judgment of the Adviser, more than one firm can offer comparable execution
services. In selecting among such firms, consideration may be given to those
firms which supply research and other services in addition to execution
services. The Adviser is authorized to pay higher commissions to brokerage firms
that provide it with investment and research information than to firms which do
not provide such services if the Adviser determines that such commissions are
reasonable in relation to the overall services provided. No specific value can
be assigned to such research services which are furnished without cost to 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 reduce its expenses materially. 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

                                       B-31


performance of 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.

     The Adviser also may place portfolio transactions, to the extent permitted
by law, with brokerage firms affiliated with the Fund, the Adviser or the
Distributor and with brokerage firms participating in the distribution of the
Fund's shares if it reasonably believes that the quality of execution and the
commission are comparable to that available from other qualified firms.
Similarly, to the extent permitted by law and subject to the same considerations
on quality of execution and comparable commission rates, the Adviser may direct
an executing broker to pay a portion or all of any commissions, concessions or
discounts to a firm supplying research or other services.

     The Adviser may place portfolio transactions at or about the same time 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 for 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 sizes of the Fund and other advisory accounts, 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.

     Effective October 31, 1996, Morgan Stanley & Co. Incorporated ("Morgan
Stanley & Co.") became an affiliate of the Adviser. Effective May 31, 1997, Dean
Witter Reynolds, Inc. ("Dean Witter") became an affiliate of the Adviser. The
Fund's Board of Trustees has adopted certain policies incorporating the
standards of Rule 17e-1 issued by the SEC under the 1940 Act which require that
the commissions paid to 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.

     The Fund paid the following commissions to all brokers and affiliated
brokers during the fiscal years shown:

                              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. The following information supplements the section
in the Fund's Prospectus captioned "Shareholder Services."

INVESTMENT ACCOUNT

     Each shareholder has an investment account under which the investor's
shares of the Fund are held by Investor Services, the Fund's transfer agent.
Investor Services performs bookkeeping, data processing and administrative
services related to the maintenance of shareholder accounts. Except as described
in the Prospectus and this Statement of Additional Information, after each share
transaction in an account, the shareholder receives a statement showing the
activity in the account. Each shareholder who has an account in any of the Van
Kampen funds will receive statements quarterly from Investor Services showing
any reinvestments of dividends and capital gain dividends 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 gain dividends and systematic purchases or
redemptions. Additional shares may be purchased at any time through authorized
dealers or by mailing a check and detailed instructions directly to Investor
Services.

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 an exchange or
redemption of the shares represented by the certificate. In addition, if such
certificates are lost the shareholder must write to Van Kampen Funds Inc., c/o
Investor Services, PO Box 218256, Kansas City, MO 64121-8256, requesting an
"Affidavit of Loss" and obtain a Surety Bond in a form acceptable to Investor
Services. On the date the letter is received, Investor Services will calculate
the fee for replacing the lost certificate equal to no more than 1.50% of the
net asset value of the issued shares, and bill the party to whom the replacement
certificate was mailed.

RETIREMENT PLANS

     Eligible investors may establish individual retirement accounts ("IRAs");
SEP; 401(k) plans; 403(b)(7) plans in the case of employees of public school
systems and certain non-profit organizations; or other pension or profit sharing
plans. Documents and forms containing detailed information regarding these plans
are available from the Distributor. Van Kampen Trust Company serves as custodian
under the IRA, 403(b)(7) and Money Purchase and Profit Sharing Keogh plans.

AUTOMATED CLEARING HOUSE ("ACH") DEPOSITS

     Shareholders can use ACH to have redemption proceeds deposited
electronically into their bank accounts. Redemption proceeds 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. To utilize this option, the
shareholder's bank must be a member of ACH. In addition, the shareholder must
fill out the appropriate section of the account application form. The
shareholder must also include a voided check or deposit slip from the bank
account into which redemption proceeds are to be deposited together with the
completed application. Once Investor Services 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 Investor Services or by calling (800) 341-2911 ((800)421-2833
for the hearing impaired).

                                       B-33


DIVIDEND DIVERSIFICATION

     A shareholder may elect, by completing the appropriate section of the
account application form or by calling (800) 341-2911 ((800) 421-2833 for the
hearing impaired), to have all dividends and capital gain dividends paid on a
class of shares of the Fund invested into shares of the same class of any of the
Participating Funds (as defined in the Prospectus) so long as the investor has a
pre-existing account for such class of shares of the other fund. Both accounts
must be of the same type, either non-retirement or retirement. If the accounts
are retirement accounts, they must both be for the same class and of the same
type of retirement plan (e.g. IRA, 403(b)(7), 401(k), Money Purchase and Profit
Sharing Keogh plans) and for the benefit of the same individual. If a qualified,
pre-existing account does not exist, the shareholder must establish a new
account subject to any requirements of the Participating Fund into which
distributions will be invested. Distributions are invested into the selected
Participating Fund, provided that shares of such Participating Fund are
available for sale, at its net asset value per share as of the payable date of
the distribution from the Fund.

SYSTEMATIC WITHDRAWAL PLAN

     A shareholder may establish a monthly, quarterly, semiannual or annual
withdrawal plan if the shareholder owns shares in a single account valued at
$10,000 or more at the next determined net asset value per share at the time the
plan is established. If a shareholder owns shares in a single account valued at
$5,000 or more at the next determined net asset value per share at the time the
plan is established, the shareholder may establish a quarterly, semiannual 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 payment
represents the proceeds of a redemption of shares on which any capital gain or
loss will be recognized. The planholder may arrange for periodic checks in any
amount not less than $25. Such a systematic withdrawal plan may also be
maintained by an investor purchasing shares for a retirement plan and can be
established on a form made available by the Fund when Van Kampen Trust Company
serves as the plan custodian. See "Shareholder Services -- Retirement Plans."

     Class B Shareholders and Class C Shareholders who establish a systematic
withdrawal plan may redeem up to 12% annually of the shareholder's initial
account balance without incurring a contingent deferred sales charge. Initial
account balance means the amount of the shareholder's investment at the time the
election to participate in the plan is made.

     Under the plan, sufficient shares of the Fund are redeemed to provide the
amount of the periodic withdrawal payment. Dividends and capital gain dividends
on shares held in accounts with systematic withdrawal plans are reinvested in
additional shares at the next determined net asset value per share. If periodic
withdrawals continuously exceed reinvested dividends and capital gain dividends,
the shareholder's original investment will be correspondingly reduced and
ultimately exhausted. Redemptions made concurrently with the purchase of
additional shares ordinarily will be disadvantageous to the shareholder because
of the duplication of sales charges. Any gain or loss realized by the
shareholder upon redemption of shares is a taxable event. The Fund reserves the
right to amend or terminate the systematic withdrawal program upon 30 days'
notice to its shareholders.

REINSTATEMENT PRIVILEGE

     A Class A Shareholder or Class B Shareholder who has redeemed shares of the
Fund may reinstate any portion or all of the net proceeds of such redemption
(and may include that amount necessary to acquire a fractional share to round
off his or her purchase to the next full share) in Class A Shares of the Fund. A
Class C Shareholder who has redeemed shares of the Fund may reinstate any
portion or all of the net proceeds of such redemption (and may include that
amount necessary to acquire a fractional share to round off his or her purchase
to the next full share) in Class C Shares of the Fund with credit given for any
contingent deferred sales charge paid upon such redemption, provided that such
shareholder has not previously exercised this reinstatement 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 (defined below) to subsequent
redemptions. Such reinstatement is made at the net asset

                                       B-34


value per share (without sales charge) next determined after the order is
received, which must be made within 180 days after the date of the redemption,
provided that shares of the Fund are available for sale. Reinstatement at net
asset value per share is also offered to participants in those eligible
retirement plans held or administered by Van Kampen Trust Company for repayment
of principal (and interest) on their borrowings on such plans, provided that
shares of the Fund are available for sale.

                              REDEMPTION OF SHARES

     Redemptions are not made on days during which the New York Stock Exchange
(the "Exchange") is closed. 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) the SEC determines trading on the Exchange is restricted; (c) the SEC
determines an emergency exists as a result of which disposal by the Fund of
securities owned by it is not reasonably practicable or it is not reasonably
practicable for the Fund to fairly determine the value of its net assets; or (d)
the SEC, by order, so permits.

     In addition, if the Fund's Board of Trustees determines that payment wholly
or partly in cash would be detrimental to the best interests of the remaining
shareholders of the Fund, the Fund may pay the redemption proceeds in whole or
in part by a distribution-in-kind of portfolio securities held by the Fund in
lieu of cash in conformity with applicable rules of the SEC. A
distribution-in-kind may result in recognition by the shareholder of a gain or
loss for federal income tax purposes when such securities are distributed, and
the shareholder may have brokerage costs and a gain or loss for federal income
tax purposes upon the shareholder's disposition of such securities.

                    CONTINGENT DEFERRED SALES CHARGE-CLASS A

     As described in the Fund's Prospectus under "Purchase of Shares--Class A
Shares," there is no sales charge payable on Class A Shares at the time of
purchase on investments of $1 million or more, but a contingent deferred sales
charge ("CDSC-Class A") may be imposed on certain redemptions made within one
year of purchase. For purposes of the CDSC-Class A, when shares of a
Participating Fund are exchanged for shares of another Participating 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 being redeemed first are any shares in the shareholder's account not
subject to a contingent deferred sales charge followed by shares held the
longest in the shareholder's account. The contingent deferred sales charge is
assessed on an amount equal to the lesser of the then current market value or
the cost of the shares being redeemed. Accordingly, no sales charge is imposed
on increases in net asset value above the initial purchase price. In addition,
no sales charge is assessed on shares derived from reinvestment of dividends or
capital gain dividends.

        WAIVER OF CLASS B AND CLASS C CONTINGENT DEFERRED SALES CHARGES

     As described in the Fund's Prospectus under "Redemption of Shares,"
redemptions of Class B Shares and Class C Shares will be subject to a contingent
deferred sales charge ("CDSC-Class B and C"). The CDSC-Class B and C is waived
on redemptions of Class B Shares and Class C Shares in the circumstances
described below:

REDEMPTION UPON DEATH OR DISABILITY

     The Fund will waive the CDSC-Class B and C on redemptions following the
death or disability of a Class B shareholder 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 of 1986, as
amended
                                       B-35


(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 death or disability, 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 partial redemption,
but only to redemptions of shares held at the time of the death or initial
determination of disability.

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 CDSC-Class B and C will be waived upon the tax-free rollover or
transfer of assets to another retirement plan invested in one or more
Participating 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 or other
contribution pursuant to Code Section 408(d)(4) or (5), the return of excess
contributions or excess deferral amounts pursuant to Code Section 401(k)(8) or
402(g)(2), the financial hardship of the employee pursuant to U.S. Treasury
regulation Section 1.401(k)-1(d)(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.

REDEMPTION PURSUANT TO THE FUND'S SYSTEMATIC WITHDRAWAL PLAN

     A shareholder may elect to participate in a systematic withdrawal plan with
respect to the shareholder's investment in the Fund. Under the systematic
withdrawal 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 sent to the designated payee of record. 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 systematic withdrawal plan.

     The amount of the shareholder's investment in the Fund at the time the
election to participate in the systematic withdrawal plan is made with respect
to the Fund is hereinafter referred to as the "initial account balance." The
amount to be systematically redeemed from the 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 systematic withdrawal plan and the ability to offer the
systematic withdrawal plan.

NO INITIAL COMMISSION OR TRANSACTION FEE

     The Fund will waive the CDSC-Class B and C in circumstances under which no
commission or transaction fee is paid to authorized dealers at the time of
purchase of shares. See "Purchase of Shares--Waiver of Contingent Deferred Sales
Charge" in the Prospectus.

                                       B-36


INVOLUNTARY REDEMPTIONS OF SHARES

     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 value of the
account up to the required minimum balance. The Fund will waive the CDSC-Class B
and C upon such involuntary redemption.

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.

                                    TAXATION

FEDERAL INCOME TAXATION OF THE FUND

     The Trust and each of its series, including the Fund, will be treated as
separate corporations for federal income tax purposes. The Fund has elected and
qualified, and intends to continue to qualify each year, to be treated as a
regulated investment company under Subchapter M of the Code. To qualify as a
regulated investment company, the Fund must comply with certain requirements of
the Code relating to, among other things, the sources of its income and
diversification of its assets.

     If the Fund so qualifies and distributes each year to its shareholders at
least an amount equal to the sum of (i) 90% of its investment company taxable
income (generally including ordinary income and net short-term capital gain, but
not net capital gain, which is the excess of net long-term capital gain over net
short-term capital loss) and (ii) 90% of its net tax-exempt interest income, and
meets certain other requirements, it will not be required to pay federal income
taxes on any income it distributes to shareholders. The Fund intends to
distribute at least the minimum amount necessary to satisfy the 90% distribution
requirement. The Fund will not be subject to federal income tax on any net
capital gain distributed to shareholders.

     To avoid a 4% excise tax, the Fund will be required to distribute, by
December 31st of each year, at least an amount equal to the sum of (i) 98% of
its ordinary income (not including tax-exempt income) for such year and (ii) 98%
of its capital gain net income (the latter of which generally is computed on the
basis of the one-year period ending on October 31st of such year) plus any
amounts that were not distributed in previous taxable years. For purposes of the
excise tax, any ordinary income or capital gain net income retained by, and
subject to federal income tax in the hands of, the Fund will be treated as
having been distributed.

     If the Fund failed to qualify as a regulated investment company or failed
to satisfy the 90% distribution requirement in any taxable year, the Fund would
be taxed as an ordinary corporation on its taxable income (even if such income
were distributed to its shareholders) and all distributions out of earnings and
profits would be taxed to shareholders as ordinary income. In addition, the Fund
could be required to recognize unrealized gains, pay taxes and make
distributions (which could be subject to interest changes) before requalifying
as a regulated investment company.

     Some of the Fund's investment practices are subject to special provisions
of the Code that may, among other things, (i) disallow, suspend or otherwise
limit the allowance of certain losses or deductions, (ii) convert lower taxed
long-term capital gain into higher taxed short-term capital gain or ordinary
income, (iii) convert an ordinary loss or a deduction into a capital loss (the
deductibility of which is more limited) and/or (iv) cause the Fund to recognize
income or gain without a corresponding receipt of cash with which to make
distributions in amounts necessary to satisfy the 90% distribution requirement
and the distribution requirements for avoiding income and excise taxes. The Fund
will monitor its transactions and may make certain tax elections 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

                                       B-37


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 to maintain its qualification
as a regulated investment company and to avoid income and excise taxes. To
generate sufficient cash to make distributions necessary to satisfy the 90%
distribution requirement and to avoid income and excise taxes, the Fund may have
to dispose of securities that it would otherwise have continued to hold.

DISTRIBUTIONS TO SHAREHOLDERS

     The Fund intends to invest in sufficient tax-exempt municipal securities to
permit payment of "exempt-interest dividends" (as defined in the Code).
Dividends paid by the Fund from the net tax-exempt interest earned from
municipal securities qualify as exempt-interest dividends if, at the close of
each quarter of its taxable year, at least 50% of the value of the total assets
of the Fund consists of such securities.

     Certain limitations on the use and investment of the proceeds of state and
local government bonds and other funds must be satisfied to maintain the
exclusion from gross income for interest on such bonds. These limitations
generally apply to bonds issued after August 15, 1986. In light of these
requirements, bond counsel qualify their opinions as to the federal tax status
of bonds issued after August 15, 1986 by making them contingent on the issuer's
future compliance with these limitations. Any failure on the part of an issuer
to comply could cause the interest on its bonds to become taxable to investors
retroactive to the date the bonds were issued.

     Except as provided below, exempt-interest dividends paid to shareholders
generally are not includable in the shareholders' gross income for federal
income tax purposes. The percentage of the total dividends paid by the Fund
during any taxable year that qualify as exempt-interest dividends will be the
same for all shareholders of the Fund receiving dividends during such year.

     Interest on certain "private-activity bonds" is an item of tax preference
subject to the federal alternative minimum tax on individuals and corporations.
The Fund invests a portion of its assets in municipal securities subject to this
provision so that a portion of its exempt-interest dividends is an item of tax
preference to the extent such dividends represent interest received from these
private-activity bonds. Accordingly, investment in the Fund could cause
shareholders to be subject to (or result in an increased liability under) the
alternative minimum tax. Per capita volume limitations on certain
private-activity bonds could limit the amount of such bonds available for
investment by the Fund.

     Exempt-interest dividends are included in determining what portion, if any,
of a person's social security and railroad retirement benefits will be
includable in gross income subject to federal income tax.

     Although exempt-interest dividends generally may be treated by Fund
shareholders as items of interest excluded from their gross income for federal
income tax purposes, 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" of a
substantial user) of the facilities financed 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 5% of
the total revenues derived from the facilities by all users, or who occupies
more than 5% of the useable area of the facilities or for whom the facilities or
a part thereof were specifically constructed, reconstructed or acquired.
Examples of "related persons" include certain related natural persons,
affiliated corporations, a partnership and its partners and an S corporation and
its shareholders.

     While the Fund expects that a major portion of its net investment income
will constitute tax-exempt interest, a portion may consist of investment company
taxable income. Distributions of the Fund's investment company taxable income
are taxable to shareholders as ordinary income to the extent of the Fund's
earnings and profits, whether paid in cash or reinvested in additional shares.
Distributions of the Fund's net capital gain as capital gain dividends, if any,
are taxable to shareholders as long-term capital gain regardless of the length
of time shares of the Fund have been held by such shareholders. Distributions in
excess of the Fund's earnings and profits will first reduce the adjusted tax
basis of a shareholder's shares and, after such adjusted tax basis is

                                       B-38


reduced to zero, will constitute capital gain to such shareholder (assuming such
shares are held as a capital asset). For a summary of the maximum tax rates
applicable to capital gain (including capital gain dividends), see "Capital
Gains Rates" below. Some or all of the interest on indebtedness incurred to
purchase or carry shares of a mutual fund which distributes exempt-interest
dividends during the year will not be deductible for federal income tax
purposes, depending upon the ratio of the exempt-interest dividends to the total
of exempt-interest dividends plus taxable dividends received by the shareholder
(excluding capital gain dividends) during the year.

     Shareholders receiving distributions in the form of additional shares
issued by the Fund will be treated for federal income tax purposes as receiving
a distribution in an amount equal to the fair market value of the shares
received, determined as of the distribution date. The basis of such shares will
equal their fair market value on the distribution date.

     The Fund will inform shareholders of the source and tax status of all
distributions promptly after the close of each calendar year. The aggregate
amount of dividends designated as exempt-interest dividends cannot exceed the
excess of 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 taxable 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.
Distributions from the Fund generally will not be eligible for the corporate
dividends received deduction.

     Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in such month and paid during January of the
following year will be treated as having been distributed by the Fund and
received by the shareholders on the December 31st prior to the date of payment.
In addition, certain other distributions made after the close of a taxable year
of the Fund may be "spilled back" and treated as paid by the Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
shareholders will be treated as having received such dividends in the taxable
year in which the distribution was actually made.

SALE OF SHARES

     The sale of shares (including transfers in connection with a redemption or
repurchase of shares) may be a taxable transaction for federal income tax
purposes. Selling shareholders will generally recognize a gain or loss in an
amount equal to the difference between their adjusted tax basis in the shares
sold and the amount received. If the shares sold are held as a capital asset,
the gain or loss will be a capital gain or loss. For a summary of the maximum
tax rates applicable to capital gains, see "Capital Gains Rates" below. Any loss
recognized upon a taxable disposition of shares held for six months or less will
be disallowed to the extent of any exempt-interest dividends received with
respect to such shares and will be treated as a long-term capital loss to the
extent of any capital gain dividends received with respect to such shares. For
purposes of determining whether shares have been held for six months or less,
the holding period is suspended for any periods during which the shareholder's
risk of loss is diminished as a result of holding one or more other positions in
substantially similar or related property or through certain options or short
sales.

CAPITAL GAINS RATES

     The maximum tax rate applicable to net capital gains recognized by
individuals and other non-corporate taxpayers investing in the Fund is (i) the
same as the maximum ordinary income tax rate for capital assets held for one
year or less or (ii) 20% for capital assets held for more than one year. The
maximum long-term capital gains rate for corporations is 35%.

BACKUP WITHHOLDING

     The Fund may be required to withhold federal income tax ("backup
withholding") from dividends and redemption proceeds paid to non-corporate
shareholders. This tax may be withheld from dividends if (i) the
                                       B-39


shareholder fails to properly furnish the Fund with its correct taxpayer
identification number, (ii) the IRS notifies the Fund that the shareholder has
failed to properly report certain interest and dividend income to the IRS and to
respond to notices to that effect or (iii) when required to do so, the
shareholder fails to certify that he or she is not subject to backup
withholding. Redemption proceeds may be subject to backup withholding under the
circumstances described in (i) above.

     Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules from payments made to a shareholder may be refunded or
credited against such shareholder's U.S. federal income tax liability, if any,
provided that the required information is furnished to the IRS.

INFORMATION REPORTING

     The Fund must report annually to the IRS and to each shareholder the amount
of dividends, capital gain dividends or gross proceeds paid to such shareholder
and the amount, if any, of tax withheld pursuant to backup withholding rules
with respect to such amounts.

GENERAL

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

                                FUND PERFORMANCE

     From time to time the Fund may advertise its total return for prior
periods. Any such advertisement would include at least average annual total
return quotations for one-year, five-year and ten-year periods. Other total
return quotations, aggregate or average, over other time periods may also be
included.

     The total return of the Fund for a particular period represents the
increase (or decrease) in the value of a hypothetical investment in the Fund
from the beginning to the end of the period. Total return is calculated by
subtracting the value of the initial investment from the ending value and
showing the difference as a percentage of the initial investment; the
calculation assumes the initial investment is made at the current maximum public
offering price (which includes the maximum sales charge for Class A Shares);
that all income dividends or capital gain dividends during the period are
reinvested in Fund shares at net asset value; and that any applicable contingent
deferred sales charge has been paid. The Fund's total return will vary depending
on market conditions, the securities comprising the Fund's portfolio, the Fund's
operating expenses and unrealized net capital gains or losses during the period.
Total return is based on historical earnings and asset value fluctuations and is
not intended to indicate future performance. No adjustments are made to reflect
any income taxes payable by shareholders on dividends or capital gain dividends
paid by the Fund or to reflect that 12b-1 fees may have changed over time.

     Average annual total return quotations are computed by finding the average
annual compounded rate of return over the period that would equate the initial
amount invested to the ending redeemable value.

     The Fund may, in supplemental sales literature, advertise non-standardized
total return figures representing the cumulative, non-annualized total return of
each class of shares of the Fund from a given date to a subsequent given date.
Cumulative non-standardized total return is calculated by measuring the value of
an initial investment in a given class of shares of the Fund at a given time,
deducting the maximum initial sales charge, if any, determining the value of all
subsequent reinvested distributions, and dividing the net change in the value of
the investment as of the end of the period by the amount of the initial
investment and expressing the result as a percentage. Non-standardized total
return will be calculated separately for each class of shares.

     Non-standardized total return calculations do not reflect the imposition of
a contingent deferred sales charge, and if any contingent deferred sales charge
imposed at the time of redemption were reflected, it would reduce the
performance quoted.

                                       B-40


     In addition to total return information, the Fund may also advertise its
current "yield." Yield figures are based on historical earnings and are not
intended to indicate future performance. Yield is determined by analyzing the
Fund's net income per share for a 30-day (or one-month) period (which period
will be stated in the advertisement), and dividing by the maximum offering price
per share on the last day of the period. A "bond equivalent" annualization
method is used to reflect a semiannual compounding.

     For purposes of calculating yield quotations, net income is determined by a
standard formula prescribed by the SEC to facilitate comparison with yields
quoted by other investment companies. Net income computed for this formula
differs from net income reported by the Fund in accordance with generally
accepted accounting principles and from net income computed for federal income
tax reporting purposes. Thus the yield computed for a period may be greater or
less than the Fund's then current dividend rate.

     The Fund's yield is not fixed and will fluctuate in response to prevailing
interest rates and the market value of portfolio securities, and as a function
of the type of securities owned by the Fund, portfolio maturity and the Fund's
expenses.

     Yield quotations should be considered relative to changes in the net asset
value of the Fund's shares, the Fund's investment policies, and the risks of
investing in shares of the Fund. The investment return and principal value of an
investment in the Fund will fluctuate so that an investor's shares, when
redeemed, may be worth more or less than their original cost.

     Yield and total return are calculated separately for Class A Shares, Class
B Shares and Class C Shares of the Fund. Total return figures for Class A Shares
include the maximum sales charge. Total return figures for Class B Shares and
Class C Shares include any applicable contingent deferred sales charge. Because
of the differences in sales charges and distribution fees, the total returns for
each class of shares will differ.

     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 differs from yield, which is a measure of
the income actually earned by the Fund's investments, and from total return
which is a measure of the income actually earned by the Fund's investments plus
the effect of any realized and unrealized appreciation or depreciation of such
investments during a stated period. Distribution rate is, therefore, not
intended to be a complete measure of the Fund's performance. Distribution rate
may sometimes be greater than yield since, for instance, it may not include the
effect of amortization of bond premiums, and may include non-recurring
short-term capital gains and premiums from futures transactions engaged in by
the Fund. Distribution rates will be computed separately for each class of the
Fund's shares.

     From time to time marketing materials may provide a portfolio manager
update, an Adviser update and discuss general economic conditions and outlooks.
The Fund's marketing materials may also show the Fund's asset class
diversification, top sector holdings and largest holdings and other Fund
information, such as duration, maturity, coupon, NAV, rating breakdown, AMT
exposure and number of issues in the portfolio. Materials may also mention how
the Distributor believes the Fund compares relative to other Van Kampen funds.
Materials may also discuss the Dalbar Financial Services study from 1984 to 1994
which studied investor cash flow into and out of all types of mutual funds. The
ten-year study found that investors who bought mutual fund shares and held such
shares outperformed investors who bought and sold. The Dalbar study conclusions
were consistent regardless of whether shareholders purchased their fund shares
in direct or sales force distribution channels. The study showed that investors
working with a professional representative have tended over time to earn higher
returns than those who invested directly. The performance of the funds purchased
by the investors in the Dalbar study and the conclusions based thereon are not
necessarily indicative of future performance of such funds or conclusions that
may result from similar studies in the future. The Fund may also be marketed on
the internet.

     In reports or other communications to shareholders or in advertising
material, the Fund may compare its performance with that of other mutual funds
as listed in the rankings or ratings prepared by Lipper Analytical Services,
Inc., CDA, Morningstar Mutual Funds or similar independent services which
monitor the performance of mutual funds with the Consumer Price Index, other
appropriate indices of investment

                                       B-41


securities, or with investment or savings vehicles. The performance information
may also include evaluations of the Fund published by nationally recognized
ranking or rating services and by nationally recognized financial publications.
Such comparative performance information will be stated in the same terms in
which the comparative data or indices are stated. Such advertisements and sales
material may also include a yield quotation as of a current period. In each
case, such total return and yield information, if any, will be calculated
pursuant to rules established by the SEC and will be computed separately for
each class of the Fund's shares. For these purposes, the performance of the
Fund, as well as the performance of other mutual funds or indices, do not
reflect sales charges, the inclusion of which would reduce the Fund's
performance. The Fund will include performance data for each class of shares of
the Fund in any advertisement or information including performance data of the
Fund.

     The Fund may also utilize performance information in hypothetical
illustrations. For example, 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.

     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's Annual Report and Semiannual Report contain additional
performance information. A copy of the Annual Report or Semiannual Report may be
obtained without charge by calling or writing the Fund at the telephone number
and address printed on the cover of this Statement of Additional Information.

                                       B-43


INDEPENDENT AUDITORS

     Independent auditors perform an annual audit of the financial statements of
the Fund. The Fund's Board of Trustees has engaged Ernst & Young LLP, located at
233 South Wacker Drive, Chicago, Illinois 60606, to be the Fund's independent
auditors.

     KPMG LLP, located at 303 East Wacker Drive, Chicago, Illinois 60601
("KPMG"), ceased being the Fund's independent auditors effective April 14, 2000.
The cessation of the client-auditor relationship between the Fund and KPMG was
based on a possible business relationship by KPMG with an affiliate of the
Fund's investment adviser. The change in independent auditors was approved by
the Fund's audit committee and the Fund's Board of Trustees, including Trustees
who are not "interested persons" of the Fund (as defined in the 1940 Act).

                       DESCRIPTION OF SECURITIES RATINGS

     STANDARD & POOR'S -- A brief description of the applicable Standard &
Poor's (S&P) rating symbols and their meanings (as published by S&P follows):

     A S&P issue credit rating is a current opinion of the creditworthiness of
an obligor with respect to a specific financial obligation, a specific class of
financial obligations, or a specific financial program (including ratings on
medium term note programs and commercial paper programs). It takes into
consideration the creditworthiness of guarantors, insurers, or other forms of
credit enhancement on the obligation and takes into account the currency in
which the obligation is denominated.

     The issue credit rating is not a recommendation to purchase, sell, or hold
a financial obligation, inasmuch as it does not comment as to market price or
suitability for a particular investor.

     Issue credit ratings are based on current information furnished by the
obligors or obtained by S&P from other sources it considers reliable. S&P does
not perform an audit in connection with any credit rating and may, on occasion,
rely on unaudited financial information. Credit ratings may be changed,
suspended, or withdrawn as a result of changes in, or unavailability of, such
information, or based on other circumstances.

     Issue credit ratings can be either long-term or short-term. Short-term
ratings are generally assigned to those obligations considered short-term in the
relevant market. In the U.S., for example, that means obligations with an
original maturity of no more than 365 days including commercial paper.
Short-term ratings are also used to indicate the creditworthiness of an obligor
with respect to put features on long-term obligations. The result is a dual
rating, in which the short-term rating addresses the put feature, in addition to
the usual long-term rating. Medium-term notes are assigned long-term ratings.

LONG-TERM ISSUE CREDIT RATINGS

     Issue credit ratings are based, in varying degrees, on the following
considerations:

     1. Likelihood of payment--capacity and willingness of the obligor to meet
        its financial commitment on an obligation 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.

     The issue rating definitions are expressed in terms of default risk. As
such, they pertain to senior obligations of an entity. Junior obligations are
typically rated lower than senior obligations, to reflect the lower priority in
bankruptcy, as noted above. (Such differentiation applies when an entity has
both senior and subordinated obligations, secured and unsecured obligations, or
operating company and holding company
                                       B-44


obligations.) Accordingly, in the case of junior debt, the rating may not
conform exactly with the category definition.

     AAA: An obligation rated "AAA" has the highest rating assigned by S&P. The
obligor's capacity to meet its financial commitment on the obligation is
extremely strong.

     AA: An obligation rated "AA" differs from the highest rated obligations
only in small degree. The obligor's capacity to meet its financial commitment on
the obligation is very strong.

     A: An obligation rated "A" is somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

     BBB: An obligation rated "BBB" exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

SPECULATIVE GRADE

     BB, B, CCC, CC, C: Obligations rated "BB", "B", "CCC", "CC" and "C" are
regarded as having significant speculative characteristics. "BB" indicates the
least degree of speculation and "C" the highest. While such obligations will
likely have some quality and protective characteristics, these may be outweighed
by large uncertainties or major exposures to adverse conditions.

     BB: An obligation rated "BB" is less vulnerable to nonpayment than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial, or economic conditions which could lead to the
obligor's inadequate capacity to meet its financial commitment on the
obligation.

     B: An obligation rated "B" is more vulnerable to nonpayment than
obligations rated "BB", but the obligor currently has the capacity to meet its
financial commitment on the obligation. Adverse business, financial, or economic
conditions will likely impair the obligor's capacity or willingness to meet its
financial commitment on the obligation.

     CCC: An obligation rated "CCC" is currently vulnerable to nonpayment, and
is dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation. In the event of
adverse business, financial, or economic conditions, the obligor is not likely
to have the capacity to meet its financial commitment on the obligation.

     CC: An obligation rated "CC" is currently highly vulnerable to nonpayment.

     C: A subordinated debt rated "C" is CURRENTLY HIGHLY VULNERABLE to
nonpayment. The "C" rating may be used to cover a situation where a bankruptcy
petition has been filed or similar action taken, but payments on this obligation
are being continued.

     D: An obligation debt rated "D" is in payment default. The "D" rating
category is used when payments on an obligation 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 or the taking of a similar action
if payments on an obligation are jeopardized. Plus (+) or minus (-): The ratings
from 'AA' to 'CCC' may be modified by the addition of a plus or minus sign to
show relative standing within the major rating categories.

     N.R.: This 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 obligation as a matter of policy.

MUNICIPAL NOTES

     A S&P note rating reflects the liquidity factors and market access risks
unique to notes. Notes due in 3 years or less will likely receive a note rating.
Notes maturing beyond 3 years will most likely receive a long-term debt rating.
The following criteria will be used in making that assessment.

                                       B-45


     -- Amortization schedule (the larger the final maturity relative to other
        maturities, the more likely it will be treated as a note); and

     -- Source of payment (the more dependent the issue is on the market for its
        refinancing, the more likely it will be treated as a note).

     Note rating symbols are as follows:

     SP-1: Strong capacity to pay principal and interest. An issue determined to
possess a very strong capacity to pay debt service is given 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.

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.

     A-1: A commercial paper obligation rated 'A-1' is rated in the highest
category by Standard & Poor's. The obligor's capacity to meet its financial
commitment on the obligation is strong. Within this category, certain
obligations are designated with a plus sign (+). This indicates that the
obligor's capacity to meet its financial commitment on these obligations is
extremely strong.

     A-2: A commercial paper obligation rated 'A-2' is somewhat more susceptible
to the adverse effects of changes in circumstances and economic conditions than
obligations in higher rating categories. However, the obligor's capacity to meet
its financial commitment on the obligation is satisfactory.

     A-3: A commercial paper obligation rated 'A-3' exhibits adequate protection
parameters. However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitment on the obligation.

     B: A commercial paper obligation rated 'B' is regarded as having
significant speculative characteristics. The obligor currently has the capacity
to meet its financial commitment on the obligation; however, it faces major
ongoing uncertainties which could lead to the obligor's inadequate capacity to
meet its financial commitment on the obligation.

     C: A commercial paper obligation rated 'C' is currently vulnerable to
nonpayment and is dependent upon favorable business, financial, and economic
conditions for the obligor to meet its financial commitment on the obligation.

     D: A commercial paper obligation rated 'D' is in payment default. The 'D'
rating category is used when payments on an obligation are not made on the date
due even if the applicable grace period has not expired, unless Standard &
Poor's 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 or the
taking of a similar action if payments on an obligation are jeopardized.

     A commercial paper 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 to
S&P by the issuer or obtained 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.

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
                                       B-46


second rating addresses only the demand feature. The long-term debt rating
symbols are used for bonds to denote the long-term maturity and the commercial
paper rating symbols for the put option (for example, 'AAA/A-1+'). With
short-term demand debt, S&P's note rating symbols are used with the commercial
paper rating symbols (for example, 'SP-1+/A-1+').

     MOODY'S INVESTORS SERVICE INC. -- A brief description of the applicable
Moody's Investors Service, Inc. (Moody's) rating symbols and their meanings (as
published by Moody's) follows:

     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 risks 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.

     Moody's assigns ratings to individual long-term debt securities issued from
medium-term note (MTN) programs, in addition to indicating ratings to MTN
programs themselves. Notes issued under MTN programs with such indicated ratings
are rated at issuance at the rating applicable to all pari passu notes issued
under the same program, at the program's relevant indicated rating, provided
such notes do not exhibit any of the characteristics listed below. For notes
with any of the following characteristics, the rating of the individual note may
differ from the indicated rating of the program:

     1) Notes containing features which link the cash flow and/or market value
        to the credit performance of any third party or parties.

     2) Notes allowing for negative coupons, or negative principal.

                                       B-47


     3) Notes containing any provision which could obligate the investor to make
        any additional payments.

     Market participants must determine whether any particular note is rated,
and if so, at what rating level. Moody's encourages market participants to
contact Moody's Ratings Desks directly if they have questions regarding ratings
for specific notes issued under a medium-term note program.

     Note: Moody's applies numerical modifiers, 1, 2, and 3 in each generic
rating classification from Aa through Caa. The modifier 1 indicates that the
obligation ranks in the higher end of its generic rating category; the modifier
2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the
lower end of that generic rating category.

SHORT-TERM EXEMPT NOTES

     In municipal debt issuance, there are three rating categories for
short-term obligations that are considered investment grade. These ratings are
designated as Moody's Investment Grade (MIG) and are divided into three
levels--MIG 1 through MIG 3.

     In addition, those short-term obligations that are of speculative quality
are designated SG, or speculative grade.

     In the case of variable rate demand obligations (VRDOs), a two-component
rating is assigned. The first element represents Moody's evaluation of the
degree of risk associated with scheduled principal and interest payments. The
second element represents Moody's evaluation of the degree of risk associated
with the demand feature, using the MIG rating scale.

     The short-term rating assigned to the demand feature of VRDOs is designated
as VMIG. When either the long- or short-term aspect of a VRDO is not rated, that
piece is designated NR, e.g., Aaa/NR or NR/VMIG 1.

     MIG ratings expire at note maturity. By contrast, VMIG rating expirations
will be a function of each issue's specific structural or credit features.

     MIG 1/VMIG 1. This designation denotes superior credit quality. Excellent
protection is afforded by established cash flows, highly reliable liquidity
support, or demonstrated broad-based access to the market for refinancing.

     MIG 2/VMIG 2. This designation denotes strong credit quality. Margins of
protection are ample, although not so large as in the preceding group.

     MIG 3/VMIG 3. This designation denotes acceptable credit quality. Liquidity
and cash-flow protection may be narrow, and market access for refinancing is
likely to be less well-established.

     SG. This designation denotes speculative-grade credit quality. Debt
instruments in this category may lack sufficient margins of protection.

TAX-EXEMPT COMMERCIAL PAPER

     Moody's short-term issuer ratings are opinions of the ability of issuers to
honor senior financial obligations and contracts. Such obligations generally
have an original maturity not exceeding one year, unless explicitly noted.

     Moody's employs the following 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. Prime-1 repayment ability
will often be evidenced by many of the following characteristics:

     -- Leading market positions in well established industries.

     -- High rates of return on funds employed.

                                       B-48


     -- Conservative capitalization structure with moderate reliance on debt and
        ample asset protection.

     -- Broad margins in earnings coverage of fixed financial charges and high
        internal cash generation.

     -- Well established access to a ranges of financial markets and assured
        sources of alternative liquidity.

     Issuers rated Prime-2 (or supporting institutions) have a strong ability to
repay of senior short-term debt obligations. This will normally be evidenced by
many of the characteristics cited above but to a lesser degree. Earnings trends
and coverage ratios, while sound, may be more subject to variation than is the
case for Prime-1 securities. Capitalization characteristics, while still
appropriate, may be more affected by external conditions. Ample alternate
liquidity is maintained.

     Issuers rated Prime-3 (or supported institutions) have an acceptable
ability for repayment of senior short-term obligations. The effect of industry
characteristics and market compositions may be more pronounced. Variability in
earnings and profitability may result in changes in the level of debt protection
measurements and may require relatively high financial leverage. Adequate
alternate liquidity is maintained.

     Issuers rated Not Prime do not fall within any of the prime rating
categories.

     In addition, in certain countries the prime rating may be modified by the
issuer's or guarantor's senior unsecured long-term debt rating.

                                       B-49


REPORT OF INDEPENDENT AUDITORS

To the Shareholders and Board of Trustees of Van Kampen Insured Tax Free Income
Fund:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Van Kampen Insured Tax Free Income Fund (the
"Fund"), as of September 30, 2001, and the related statements of operations for
the year then ended, and the statements of changes in net assets and financial
highlights for the two years then ended. 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. The financial highlights of the Fund
for each of the indicated years in the period ended September 30, 1999 were
audited by other auditors whose report dated November 5, 1999 expressed an
unqualified opinion on those financial highlights.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States. 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 September 30, 2001, by correspondence with the custodian and brokers
or by other appropriate auditing procedures where replies from brokers were not
received. 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 the
Fund at September 30, 2001, the results of its operations for the year then
ended, and the changes in its net assets and financial highlights for each of
the two years in the period then ended, in conformity with accounting principles
generally accepted in the United States.

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Insured Tax Free Income Fund (the "Fund") is organized as a series of
the Van Kampen Tax Free Trust (the "Trust"), a Delaware business trust and is
registered as a diversified open-end management investment company under the
Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's
investment objective is to provide investors 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 Fund commenced investment operations on December 14, 1984. The
distribution of the Fund's Class B and Class C Shares commenced on May 3, 1993
and August 13, 1993, respectively.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Short-term securities with remaining maturities of 60 days or less are valued at
amortized cost, which approximates market value.

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

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond
premium is amortized and original issue discount is accreted over the expected
life

                                       F-26

of each applicable security. Income and expenses of the Fund are allocated on a
pro rata basis to each class of shares, except for distribution and service fees
and transfer agency costs which are unique to each class of shares.

    In November, 2000 the American Institute of Certified Public Accountants
(AICPA) issued a revised version of the AICPA Audit and Accounting Guide for
Investments Companies (the "Guide"). The revised version of the Guide is
effective for annual financial statements issued for fiscal years beginning
after December 15, 2000 and will require investments companies to amortize
premiums and accrete discounts on fixed income securities. The Fund currently
does not accrete market discount on fixed income securities. Upon adoption, the
Fund will be required to record a cumulative effect adjustment to reflect the
accretion of market discount. The adjustment will increase accumulated
undistributed net investment income and reduce unrealized appreciation on
securities and therefore will not impact total net assets. As of September 30,
2001, the cumulative effect adjustment to reflect the accretion of market
discount would be $757,311.

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 September 30, 2001, the Fund intends to utilize its capital loss
carryforward of $1,991,890.

    At September 30, 2001, for federal income tax purposes, cost of long- and
short-term investments is $1,107,410,164; the aggregate gross unrealized
appreciation is $73,364,853 and the aggregate gross unrealized depreciation is
$720,324, resulting in net unrealized appreciation on long- and short-term
investments of $72,644,529.

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.

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

F. INSURANCE EXPENSES The Fund typically invests in insured bonds. Any portfolio
securities not specifically covered by a primary insurance policy are insured

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $896,669,851 and
$890,286,234, 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 unrealized
appreciation/depreciation.

    The Fund invests in 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 Rate security is one where the coupon is inversely
indexed to a short-term floating interest rate multiplied by a specified factor.
As the

NOTES TO
FINANCIAL STATEMENTS

floating rate rises, the coupon is reduced. Conversely as the floating rate
declines, the coupon is increased. These instruments are typically used by the
Fund to enhance the yield of the portfolio.

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

6. DISTRIBUTION AND SERVICE PLANS

With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund
and its shareholders have adopted a distribution plan pursuant to Rule 12b-1
under the 1940 Act, as amended, and a service plan (collectively the "Plans").
The Plans govern payments for: the distribution of the Fund's Class A Shares,
Class B Shares and Class C Shares; the provision of ongoing shareholder services
with respect to such classes of shares; and maintenance of shareholder accounts
with respect to such classes of shares.

    Annual fees under the Plans of up to .25% of Class A average daily net
assets and 1.00% each of Class B and Class C average daily net assets are
accrued daily. Included in these fees for the year ended September 30, 2001, are
payments retained by Van Kampen of approximately $614,100 and payments made to
Morgan Stanley DW, Inc., an affiliate of the Adviser, of approximately $71,700.

                              GENERAL INFORMATION

  The Trust is an unincorporated business trust established under the laws of
the State of Delaware by an Agreement and Declaration of Trust (the "Declaration
of Trust") dated May 10, 1995. The Trust was originally organized in 1985 under
the name Van Kampen Merritt Tax Free Trust as a Massachusetts business trust
(the "Massachusetts Trust"). The Massachusetts Trust was reorganized into the
Trust under the name Van Kampen American Capital Tax Free Trust on July 31,
1995. The Trust was created for the purpose of facilitating the Massachusetts
Trust reorganization into a Delaware business trust. On July 14, 1998, the Trust
adopted its current name.

  The Fund was originally organized in 1994 under the name Van Kampen Merritt
Florida Insured Tax Free Income Fund as a sub-trust of the Massachusetts Trust.
The Fund was reorganized as a series of the Trust under the name Van Kampen
American Capital Florida Insured Tax Free Income Fund on July 31, 1995. On July
14, 1998, the Fund adopted its current name.

  Van Kampen Investment Advisory Corp. (the "Adviser" or "Advisory Corp."), Van
Kampen Funds Inc. (the "Distributor"), and Van Kampen Investor Services Inc.
("Investor Services") are wholly owned subsidiaries of Van Kampen Investments
Inc. ("Van Kampen Investments"), which is an indirect wholly owned subsidiary of
Morgan Stanley Dean Witter & Co. ("Morgan Stanley"). The principal office of the
Trust, the Fund, the Adviser, the Distributor and Van Kampen Investments is
located at 1 Parkview Plaza, Oakbrook Terrace, Illinois 60181-5555. The
principal office of Investor Services is located at 7501 Tiffany Springs
Parkway, Kansas City, Missouri 64153.

  Morgan Stanley is a preeminent global financial services firm that maintains
leading market positions in each of its three primary businesses: securities,
asset management and credit services.

  The authorized capitalization of the Trust consists of an unlimited number of
shares of beneficial interest, par value $0.01 per share, which can be divided
into series, such as the Fund, and further subdivided into classes of each
series. 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 currently offers three classes of shares, designated as Class A
Shares, Class B Shares and Class C Shares. Other classes may be established from
time to time in accordance with the provisions of the Declaration of Trust. Each
class of shares of the Fund generally is identical in all respects except that
each class of shares is subject to its own sales charge schedule and its own
distribution expenses. Each class of shares also has exclusive voting rights
with respect to its distribution fee.

  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 and separate votes are taken by each class of a series on matters
affecting an individual class of such series. For example, a change in
investment policy for a series would be voted upon by shareholders of only the
series involved and a change in the distribution fee for a class of a series
would be voted upon by shareholders of only the class of such series involved.
Except as otherwise described in the Prospectus or herein, shares do not have
cumulative voting rights, preemptive rights or any conversion, subscription or
exchange rights.

  The Trust does not contemplate holding regular meetings of shareholders to
elect Trustees or otherwise. However, the holders of 10% or more of the
outstanding shares may by written request require a meeting to consider the
removal of Trustees by a vote of two-thirds of the shares then outstanding cast
in person or by proxy at such meeting. The Fund will assist such holders in
communicating with other shareholders of the Fund to the extent required by the
Investment Company Act of 1940, as amended (the "1940 Act"), or rules or
regulations promulgated by the Securities and Exchange Commission ("SEC").

  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 debts and expenses of the Fund
have been paid. Since Class B Shares and Class C Shares have

                                       B-2


higher distribution fees and transfer agency costs, the liquidation proceeds to
holders of Class B Shares and Class C Shares are likely to be less than the
liquidation proceeds to holders of Class A Shares.

  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
outstanding and entitled to vote (or such higher vote as may be required by the
1940 Act or other applicable law) and except that the Trustees cannot amend the
Declaration of Trust to impose any liability on shareholders, make any
assessment on shares or impose liabilities on the Trustees without approval from
each affected shareholder or Trustee, as the case may be.

  Statements contained in this Statement of Additional Information as to the
contents of any contract or other document referred to are not necessarily
complete, and, in each instance, reference is made to the copy of such contract
or other document filed as an exhibit to the Registration Statement of which
this Statement of Additional Information forms a part, each such statement being
qualified in all respects by such reference.

  As of January 8, 2002, no person was known by the Fund to own beneficially or
to hold of record 5% or more of the outstanding Class A Shares, Class B Shares
or Class C Shares of the Fund, except as follows:

                    INVESTMENT OBJECTIVE, POLICIES AND RISKS

  The following disclosure supplements the disclosure set forth under the same
caption in the Prospectus and does not, standing alone, present a complete or
accurate explanation of the matters disclosed. Readers must refer also to this
caption in the Prospectus for a complete presentation of the matters disclosed
below.

MUNICIPAL SECURITIES

  Municipal securities include long-term obligations, which often are 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. The Fund may, however, invest in shorter term municipal
securities when yields are greater than yields available on longer term
municipal securities, for temporary defensive purposes or when redemption
requests are expected. The two principal classifications of municipal securities
are "general obligation" and "revenue" or "special obligation" securities, which
include "industrial revenue bonds." 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 or special obligation securities 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. The Fund
may also invest in "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.

  Also included within the general category of municipal securities are
participations in lease obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of state and local
governments or authorities used to finance the acquisition of equipment and
facilities. Lease obligations generally do not constitute general obligations of
the municipality for which the municipality's taxing power is pledged. A lease
obligation is ordinarily backed by the municipality's covenant to budget for,
appropriate and make the payments due under the lease obligation. However,
certain lease obligations contain "non-appropriation" clauses which provide that
the municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a
yearly basis. A risk exists that the municipality will not, or will be unable
to, appropriate money in the future in the event of political changes, changes
in the economic viability of the project, general economic changes or for other
reasons. In addition to the "non-appropriation" risk, these securities represent
a relatively new type of financing that has not yet developed the depth of
marketability associated with more conventional bonds. Although
"non-appropriation" lease obligations are often secured by an assignment of the
lessee's interest in the leased property, management and/or disposition of the
property in the event of foreclosure could be costly, time consuming and result
in unsatisfactory recoupment of the Fund's original investment. Additionally,
use of the leased property may be limited by state or local law to a specified
use thereby further limiting ability to rent. There is no limitation on the
percentage of the Fund's assets that may be invested in "non-appropriation"
lease obligations. In evaluating such lease obligations, the Adviser will
consider such factors as it deems appropriate, which factors may include (a)
whether the lease can be cancelled, (b) the ability of the lease obligee to
direct the sale of the underlying assets, (c) the general creditworthiness of
the lease obligor, (d) the likelihood that the municipality will discontinue
appropriating funding for the leased property in the event such property is no
longer considered essential by the municipality, (e) the legal recourse of the
lease obligee in the event of such a failure to appropriate funding and (f) any
limitations which are imposed on the lease obligor's ability to utilize
substitute property or services than those covered by the lease obligation.
"Non-Substitution" clauses in municipal lease transactions have recently been
held unenforceable in Florida as violative of public policy. The Fund will
invest in lease obligations which contain non-appropriation clauses only if such
obligations are rated investment grade at the time of investment.

  Also included in the term municipal securities are participation certificates
issued by state and local governments or authorities to finance the acquisition
of equipment and facilities. They may represent participations in a lease, an
installment purchase contract or a conditional sales contract.

                                       B-4


  The Fund may purchase floating and variable rate demand notes, which are
municipal securities normally having a stated maturity in excess of one year,
but which permit the holder to demand payment of principal at any time or at
specified intervals. The issuer of such notes normally has a corresponding
right, after a given period, to prepay at its discretion upon notice to the
noteholders the outstanding principal amount of the notes plus accrued interest.
The interest rate on a floating rate demand note is based on a known lending
rate, such as a bank's prime rate, and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is adjusted
automatically at specified intervals.

  The Fund also may invest up to 20% of its total assets in derivative variable
rate 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. Derivative variable rate
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
variable rate securities in response to changes in market rates of interest
generally will be larger than comparable changes in the value of an equal
principal amount of a fixed rate municipal security having similar credit
quality, redemption provisions and maturity.

  The Fund also may acquire custodial receipts or certificates underwritten by
securities dealers or banks that evidence ownership of future interest payments,
principal payments or both on certain municipal securities. The underwriter of
these certificates or receipts typically purchases municipal securities and
deposits the securities in an irrevocable trust or custodial account with a
custodian bank, which then issues receipts or certificates that evidence
ownership of the periodic unmatured coupon payments and the final principal
payment on the obligations. Although under the terms of a custodial receipt, the
Fund typically would be authorized to assert its rights directly against the
issuer of the underlying obligation, the Fund could be required to assert
through the custodian bank those rights as may exist against the underlying
issuer. Thus, in the event the underlying issuer fails to pay principal or
interest when due, the Fund may be subject to delays, expenses and risks that
are greater than those that would have been involved if the Fund had purchased a
direct obligation of the issuer. In addition, in the event that the trust or
custodial account in which the underlying security has been deposited is
determined to be an association taxable as a corporation, instead of a
non-taxable entity, the yield on the underlying security would be reduced in
recognition of any taxes paid.

  The "issuer" of municipal securities generally is deemed to be the
governmental agency, authority, instrumentality or other political subdivision,
or the non-governmental user of a revenue bond-financed facility, the assets and
revenues of which will be used to meet the payment obligations, or the guarantor
of such payment obligations, of the municipal securities.

  Although the Fund invests primarily in municipal securities insured as to
timely payment of principal and interest, municipal securities, like other debt
obligations, are subject to the risk of non-payment. The ability of issuers of
municipal securities to make timely payments of interest and principal may be
adversely impacted in general economic downturns and as relative governmental
cost burdens are allocated and reallocated among federal, state and local
governmental units. Such non-payment would result in a reduction of income to
the Fund, and could result in a reduction in the value of the municipal security
experiencing non-payment and a potential decrease in the net asset value of the
Fund. Issuers of municipal securities might seek protection under the bankruptcy
laws. In the event of bankruptcy of such an issuer, the Fund could experience
delays and limitations with respect to the collection of principal and interest
on such municipal securities and the Fund may not, in all circumstances, be able
to collect all principal and interest to which it is entitled. To enforce its
rights in the event of a default in the payment of interest or repayment of
principal, or both, the Fund may take possession of and manage the assets
securing the issuer's obligations on such securities, which may increase the
Fund's operating expenses and adversely affect the net asset value of the Fund.
Any income derived from the Fund's ownership or operation of such assets may not
be tax-exempt. In addition, the Fund's intention to qualify as a "regulated
investment company" under the Internal Revenue Code of 1986, as amended (the
"Code"), may limit the extent to which the Fund may exercise its rights by
taking possession of such assets, because as a regulated investment company the
Fund is subject to certain limitations on its investments and on the nature of
its income. Further, in connection with the working out or restructuring of a
defaulted security, the Fund may acquire additional securities of the issuer,
the acquisition of which may be deemed to be a loan of money or property. Such
additional securities should be considered speculative with respect to the
capacity to pay interest or repay principal in accordance with their terms.
                                       B-5


INSURANCE

  As described in the Prospectus, the Fund invests primarily in municipal
securities which are either pre-insured under a policy obtained for such
securities prior to the purchase of such securities or are insured under
policies obtained by the Fund to cover otherwise uninsured securities.

  ORIGINAL ISSUE INSURANCE. Original Issue Insurance is purchased with respect
to a particular issue of municipal securities by the issuer thereof or a third
party in conjunction with the original issuance of such municipal securities.
Under such insurance, the insurer unconditionally guarantees to the holder of
the insured municipal security the timely payment of principal and interest on
such obligation when and as such payments shall become due but shall not be paid
by the issuer; except that in the event of any acceleration of the due date of
the principal by reason of mandatory or optional redemption (other than
acceleration by reason of a mandatory sinking fund payment), default or
otherwise, the insured payments may be made in such amounts and at such times as
payments of principal would have been due had there not been such acceleration.
The insurer is responsible for such payments less any amounts received by the
holder from any trustee for the municipal security issuers or from any other
source. Original Issue Insurance generally does not insure payment on an
accelerated basis, the payment of any redemption premium (except with respect to
certain premium payments in the case of certain small issue industrial
development and pollution control municipal securities), the value of the shares
of the Fund or the market value of municipal securities, or payments of any
tender purchase price upon the tender of the municipal securities. Original
Issue Insurance also does not insure against nonpayment of principal of or
interest on municipal securities resulting from the insolvency, negligence or
any other act or omission of the trustee or other paying agent for such
obligations.

  In the event that interest on or principal of a municipal security covered by
insurance is due for payment but is unpaid by reason of nonpayment by the issuer
thereof, the applicable insurer will make payments to its fiscal agent (the
"Fiscal Agent") equal to such unpaid amounts of principal and interest not later
than one business day after the insurer has been notified that such nonpayment
has occurred (but not earlier than the date of such payment is due). The Fiscal
Agent will disburse to the Fund the amount of principal and interest which is
then due for payment but is unpaid upon receipt by the Fiscal Agent of (i)
evidence of the Fund's right to receive payment of such principal and interest
and (ii) evidence, including any appropriate instrument of assignment, that all
of the rights of payment of such principal or interest then due for payment
shall thereupon vest in the insurer. Upon payment by the insurer of any
principal or interest payments with respect to any municipal securities, the
insurer shall succeed to the rights of the Fund with respect to such payment.

  Original Issue Insurance remains in effect as long as the municipal securities
covered thereby remain outstanding and the insurer remains in business,
regardless of whether the Fund ultimately disposes of such municipal securities.
Consequently, Original Issue Insurance may be considered to represent an element
of market value with respect to the municipal securities so insured, but the
exact effect, if any, of this insurance on such market value cannot be
estimated.

  SECONDARY MARKET INSURANCE.  Subsequent to the time of original issuance of a
municipal security, the Fund or a third party may, upon the payment of a single
premium, purchase insurance on such municipal security. Secondary Market
Insurance generally provides the same type of coverage as is provided by
Original Issue Insurance and, as is the case with Original Issue Insurance,
Secondary Market Insurance remains in effect as long as the municipal security
covered thereby remains outstanding and the insurer remains in business,
regardless of whether the Fund ultimately disposes of such municipal security.
All premiums respecting municipal securities covered by Original Issue Insurance
or Secondary Market Insurance are paid in advance by the issuer or other party
obtaining the insurance.

  One of the purposes of acquiring Secondary Market Insurance with respect to a
particular municipal security would be to 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

                                       B-6


proceeds of a sale by the Fund of such obligation, as insured, would exceed the
current value of such obligation plus the cost of the Secondary Market
Insurance.

  PORTFOLIO INSURANCE.  The Portfolio Insurance policies obtained by the Fund
would insure the payment of principal and interest on specified eligible
municipal securities purchased by the Fund. Except as described below, Portfolio
Insurance generally provides the same type of coverage as is provided by
Original Issue Insurance or Secondary Market Insurance. Municipal securities
insured under one Portfolio Insurance policy generally would not be insured
under any other policy purchased by the Fund. A municipal security is eligible
for coverage under a policy if it meets certain requirements of the insurer.
Portfolio Insurance is intended to reduce financial risk, but the cost thereof
and compliance with investment restrictions imposed under the policy will reduce
the yield to shareholders of the Fund. If a municipal security already is
covered by Original Issue Insurance of Secondary Market Insurance, the Fund is
not required to additionally insure any such municipal security under any policy
of Portfolio Insurance that the Fund may purchase.

  Portfolio Insurance policies are effective only as to municipal securities
owned and held by the Fund, and do not cover municipal securities for which the
contract for purchase fails. A "when-issued" municipal security will be covered
under a Portfolio Insurance policy upon the settlement date of the issue of such
"when-issued" municipal security.

  In determining whether to insure municipal securities held by the Fund, an
insurer will apply its own standards, which correspond generally to the
standards it has established for determining the insurability of new issues of
municipal securities. See "Original Issue Insurance" above.

  Each Portfolio Insurance policy will be non-cancellable and will remain in
effect so long as the Fund is in existence, the municipal securities covered by
the policy continue to be held by the Fund, and the Fund pays the premiums for
the policy. Each insurer generally will reserve the right at any time upon 90
days written notice to the Fund to refuse to insure any additional securities
purchased by the Fund after the effective date of such notice. The Board of
Trustees of the Fund generally will reserve the right to terminate each policy
upon seven days written notice to an insurer if it determines that the cost of
such policy is not reasonable in relation to the value of the insurance to the
Fund.

  Each Portfolio Insurance policy shall terminate as to any municipal security
that has been redeemed from or sold by the Fund on the date of such redemption
or the settlement date of such sale, and an insurer shall not have any liability
thereafter under a policy as to any such municipal security, except that if the
date of such redemption or the settlement date of such sale occurs after a
record date and before the related payment date with respect to any such
municipal security, the policy will terminate as to such municipal security on
the business day immediately following such payment date. Each policy will
terminate as to all municipal securities covered thereby on the date on which
the last of the covered municipal securities mature, are redeemed or are sold by
the Fund.

  One or more policies of Portfolio Insurance may provide the Fund, pursuant to
an irrevocable commitment of the insurer, with the option to exercise the right
to obtain permanent insurance ("Permanent Insurance") with respect to a
municipal security that is to be sold by the Fund. The Fund would exercise the
right to obtain Permanent Insurance upon payment of a single, predetermined
insurance premium payable from the proceeds of the sale of such municipal
security. It is expected that the Fund will exercise the right to obtain
Permanent Insurance for a municipal security only if, in the opinion of the
Adviser, upon such exercise the net proceeds from the sale by the Fund of such
obligation, as insured, would exceed the proceeds from the sale of such
obligation without insurance. The Permanent Insurance premium with respect to
each such obligation is determined based upon the insurability of each such
obligation as of the date of purchase by the Fund and will not be increased or
decreased for any change in the creditworthiness of such obligation unless such
obligation is in default as to payment of principal or interest, or both. In
such event, the Permanent Insurance premium shall be subject to an increase
predetermined at the date of purchase by the Fund.

  Because each Portfolio Insurance policy will terminate as to municipal
securities sold by the Fund on the date of sale, in which event the insurer will
be liable only for those payments of principal and interest that are then due
and owing (unless Permanent Insurance is obtained by the Fund), the provision
for this insurance will not enhance the marketability of securities held by the
Fund, whether or not the securities are in default or

                                       B-7


in significant risk of default. On the other hand, since Original Issue
Insurance and Secondary Market Insurance will remain in effect as long as
municipal securities covered thereby are outstanding, such insurance may enhance
the marketability of such securities even when such securities are in default or
in significant risk of default, but the exact effect, if any, on the
marketability cannot be estimated. Accordingly, the Fund may determine to retain
or, alternatively, to sell municipal securities covered by Original Issue
Insurance or Secondary Market Insurance that are in default or in significant
risk of default.

  GENERAL.  It is anticipated that certain of the municipal securities to be
purchased by the Fund will be insured under policies obtained by persons other
than the Fund. In instances in which the Fund purchases municipal securities
insured under policies obtained by persons other than the Fund, the Fund does
not pay the premiums for such policies; rather the cost of such policies may be
reflected in a higher purchase price for such municipal securities. Accordingly,
the yield on such municipal securities may be lower than that on similar
uninsured municipal securities. Premiums for a Portfolio Insurance Policy
generally are paid by the Fund monthly, and are adjusted for purchases and sales
of municipal securities covered by the policy during the month. The yield on the
Fund's portfolio is reduced to the extent of the insurance premiums paid by the
Fund which, in turn, will depend upon the characteristics of the covered
municipal securities held by the Fund. In the event the Fund were to purchase
Secondary Market Insurance with respect to any municipal securities then covered
by a Portfolio Insurance policy, the coverage and the obligation of the Fund to
pay monthly premiums under such policy would cease with such purchase.

  There can be no assurance that insurance of the kind described above will
continue to be available to the Fund. In the event that such insurance is no
longer available or that the cost of such insurance outweighs the benefits to
the Fund in the view of the Board of Trustees, the Board will consider whether
to modify the investment policies of the Fund, which may require the approval of
shareholders. In the event the claims-paying ability rating of an insurer of
municipal securities in the Fund's portfolio were to be lowered from AAA by
Standard and Poor's ("S&P"), Aaa by Moody's Investor Services, Inc. ("Moody's")
or an equivalent rating by another nationally recognized statistical ratings
organization ("NRSRO"), or if the Adviser anticipates such a lowering or
otherwise does not believe an insurer's claims-paying ability merits its
existing triple-A rating, the Fund could seek to obtain additional insurance
from an insurer whose claims-paying ability is rated AAA by S&P, Aaa by Moody's
or an equivalent rating by another NRSRO, or if the Adviser determines that the
cost of obtaining such additional insurance outweigh the benefits, the Fund may
elect not to obtain additional insurance. In making such determination, the
Adviser will consider the cost of the additional insurance, the new
claims-paying ability rating and financial condition of the existing insurer and
the creditworthiness of the issuer or guarantor of the underlying municipal
securities. The Adviser also may determine not to purchase additional insurance
in such circumstances if it believes that the insurer is taking steps which will
cause its triple-A claims paying ability rating to be restored promptly.

  Although the Adviser periodically reviews the financial condition of each
insurer, there can be no assurance that the insurers will be able to honour
their obligations under all circumstances. The Fund cannot predict the
consequences of a state takeover of an insurer's obligations and, in particular,
whether such an insurer (or its state regulatory agency) could or would honour
all of the insurer's contractual obligations including any outstanding insurance
contracts insuring the timely payment of principal and interest on municipal
securities. The Fund cannot predict the impact which such events might have on
the market values of such municipal security. In the event of a default by an
insurer on its obligations with respect to any municipal securities in the
Fund's portfolio, the Fund would look to the issuer or guarantor of the relevant
municipal securities for payments of principal and interest and such issuer or
guarantor may not be rated AAA by S&P, Aaa by Moody's or an equivalent rating by
another NRSRO. Accordingly, the Fund could be exposed to greater risk of
non-payment in such circumstances which could adversely affect the Fund's net
asset value. 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

                                       B-8


(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.

SPECIAL CONSIDERATIONS REGARDING FLORIDA MUNICIPAL SECURITIES

  GENERAL.  As described in the Prospectus, except during temporary periods, the
Fund will invest substantially all of its assets in Florida municipal
securities. The Fund is therefore susceptible to political, economic, regulatory
or other factors affecting issuers of Florida municipal securities. In addition,
the specific Florida municipal securities in which the Fund will invest are
expected to change from time to time. The following information constitutes only
a brief summary of some of the complex factors which may have an impact on the
financial situation of issuers of Florida municipal securities and does not
purport to be a complete or exhaustive description of all adverse conditions to
which issuers of Florida municipal securities may be subject and is not
applicable to "conduit" obligations, such as industrial development revenue
bonds, with respect to which the public issuer itself has no financial
responsibility. Such information is derived from certain official statements of
the State of Florida published in connection with the issuance of specific State
of Florida securities, as well as from other publicly available documents. Such
information has not been independently verified by the Fund and may not apply to
all Florida municipal securities acquired by the Fund. The Fund assumes no
responsibility for the completeness or accuracy of such information.

  Many factors, including national, economic, social and environmental policies
and conditions, that are not within the control of such issuers, could have an
adverse impact on the financial condition of such issuers. The Fund cannot
predict whether or to what extent such factors or other factors may affect the
issuers of Florida municipal securities, the market value or marketability of
such securities or the ability of the respective issuers of such securities
acquired by the Fund to pay interest on or principal of such securities. The
creditworthiness of obligations issued by local Florida issuers may be unrelated
to the creditworthiness of obligations issued by the State of Florida, and there
is no responsibility on the part of the State of Florida to make payments on
such local obligations. There may be specific factors that are applicable in
connection with investment in the obligations of particular issuers located
within Florida, and it is possible the Fund will invest in obligations of
particular issuers as to which such specific factors are applicable. However,
the information set forth below is intended only as a general summary and not as
a discussion of any specific factors that may affect any particular issuer of
Florida municipal securities.

  Florida state and local government obligations may be adversely affected by
political and economic conditions and developments within the State of Florida
and the nation as a whole. Florida's economic outlook is generally projected to
reflect the national economic outlook. The Florida constitution and statutes
require a balanced budget, which may affect the ability of the State of Florida
to issue and/or repay its obligations. In addition, various limitations on the
State of Florida, its governmental agencies and its local governments, including
school and special districts and authorities, may inhibit the ability of these
issuers to repay existing indebtedness and issue additional indebtedness. The
ability of such issuers to repay revenue bonds may also depend on the success of
the capital projects to which they relate. The ability of such issuers to repay
general obligation bonds will also depend on the success of such issuer
maintaining its ad valorem tax base.

  INVESTMENT PRACTICES AND POLICIES OF ISSUERS OF FLORIDA MUNICIPAL
ISSUERS. Florida law does provide certain restrictions on the investment of
funds for the State of Florida and its local governments; however, with respect
to all municipalities and its charter counties, such restrictions may be limited
by the constitutional home rule powers of such entities. Although the Florida
municipal securities which may be purchased by the Fund will be insured, only
those securities that are insured by Original Issuance Insurance will contain
restrictions on investments imposed by the issuer of such insurance. Because
statutory restrictions on investments and investment policies with respect to
the investment of funds is limited by constitutional home rule powers, there can
be no assurance as to whether any issuer will suffer losses as a result of
investments or the magnitude or any such losses.

  POPULATION, INCOME AND EMPLOYMENT.  Population: Florida ranks as the fourth
most populous state, with an estimated population of 16.34 million as of April
1, 2001. From 1990 to 2000, the U.S. population has increased about 1% annually,
while Florida's population has averaged a 1.8% annual increase due primarily to
net in-migration. During that period, 16% of the State's population growth was
due to the excess of births over

                                       B-9


deaths, and 84% to net in-migration. Approximately one-third of such
in-migration was from foreign countries, with the rest from other states.

  Since 1990, the ratio of Florida's working age population to total State
population has been about 60% and is not expected to change appreciably between
2000 and 2010. The population aged 85 and older was projected to grow by 29%
between 1995 and 2000, and by 23% to 409,000, between 2000 and 2005.

  Employment: Since 1990, Florida's working age population (age 18-64) increased
17%, while the number of employed persons increased approximately 20.2%. The
trade and services sectors of the State's economy are growing. In 1998, services
constituted 36% of the State's total non-farm jobs, compared to 32.6% five years
earlier. The total number of jobs increased 20% while jobs in trade and services
increased 17% and 32%, respectively. Of the 20 public companies in Florida with
the most revenues in 1998, 13 are Fortune 500 companies, with headquarters in
the State (FORTUNE MAGAZINE, April 17, 2000).

  The unemployment rate for Florida in 2001 was 3.7% while the nation's rate in
2001 was 4.2%.

  Income: Historically, Florida's total personal income has grown more than that
of the U.S. and the other southeastern states. From 1990 to 1999, Florida's
total nominal personal income grew by 62% and per capita income expanded
approximately 41%. For the nation, total and per capita personal income
increased by 59% and 46%, respectively. Because Florida has an older and
proportionally larger retirement population than most states, property income
(dividends, interest, and rent) and transfer payments (social security,
retirement, disability, unemployment insurance, worker's compensation and
veterans benefits) are major sources of income.

  TOURISM INDUSTRY.  Tourism remains an important aspect of the Florida economy.
Its financial impact is reflected in a broad range of market sectors, such as
transportation, communications, retail trade and services, and in State tax
revenues generated by business activities which cater to visitors, such as
hotels, restaurants, admissions and gift shops. According to Visit Florida, the
direct support organization for the Florida Commission on Tourism, approximately
48.7 million people visited the State in 1998. According to the Florida
Statistical Abstract, (University of Florida, Bureau of Economic and Business
Research, 2000) during Fiscal year 1999-2000, the State licensed 4,705 hotels
and motels with 370,961 total units. During the same period 37,076 food service
establishments were licensed, with seating capacity of 3,187,167. Visitors to
the State's public parks and recreation areas totaled 16,451,587 for Fiscal year
1999-2000, a 12.3% increase over the prior year.

  STATE FINANCIAL OPERATIONS.  Financial operations of the State covering all
receipts and expenditures are maintained through the use of four funds--the
General Revenue Fund, Trust Funds, the Working Capital Fund, and the Budget
Stabilization Fund. Major sources of tax revenues to the General Revenue Fund
are the sales and use tax, corporate income tax, intangible personal property
tax, beverage tax and estate tax. Unlike many other jurisdictions, the State of
Florida does not levy ad valorem taxes on real property or tangible personal
property, nor does it impose a personal income tax.

  The sales and use tax is the largest single source of tax receipts in Florida.
The sales tax is 6% of the sales price of tangible personal property sold at
retail in the State. The use tax is at 6% of the cost price of tangible personal
property when the same is not sold but is used, or stored for use, in the State.
Slightly less than 10% of the sales tax is designated for local governments and
is distributed to the respective counties in which collected for use by the
county and the municipalities therein. In addition to this distribution, local
governments may (by referendum) assess a 0.5% or 1% discretionary sales surtax
within their county, for certain purposes. The proceeds of these surtaxes are
required to be applied to the purposes for which such surtax is assessed. In
each of the past three legislative sessions of the Florida Legislature, measures
were enacted which temporarily waived collection of the sales tax on clothing
priced under certain amounts. General revenue was estimated to decrease by
$142.7 million in Fiscal Year 1999-2000, and $35.5 million in Fiscal Year
2000-01 as a result of the sales tax waivers.

  Receipts of the sales and use tax, with the exception of the tax on gasoline
and special fuels, are credited to either the General Revenue Fund, the Solid
Waste Management Trust Fund, or counties and cities. Legislation was enacted in
2000 which provides that 2.25% of sales tax receipts are to be deposited in the

                                       B-10


Revenue Sharing Trust Fund for Counties in lieu of intangible personal property
taxes which were so distributed under prior law.

  For the State fiscal year which ended June 30, 2001, sales and use tax revenue
allocated to the State's General Revenue Fund were $13,945.7 million.

  The second largest source of State tax receipts, including those distributed
to local governments, is the tax on motor fuels. However, these revenues are
almost entirely trust funds dedicated for specific purposes and are not included
in the State General Revenue Fund. Taxes on motor fuels (gasoline and diesel
fuel) include several distinct fuel taxes: (1) the State sales tax on motor
fuels, levied at 6% of the average retail price per gallon of fuel, not to fall
below 6.9 cents per gallon; (2) the State excise tax of four cents per gallon of
motor fuel, with proceeds distributed to local governments; (3) the State
Comprehensive Enhanced Transportation System (SCETS) tax, which is levied at a
rate in each county equal to two-thirds of the sum of the county's local option
motor fuel taxes; (4) aviation fuel, which air carriers may choose to be taxed
at 6.9 cents per gallon or 8% of the retail price of fuel, not to be less than
4.4 cents per gallon; and (5) local option motor fuel taxes, which may range
between one cent to 12 cents per gallon.

  Most of the proceeds of the sales tax on motor fuels are deposited into the
State Transportation Trust Fund for road maintenance and construction. The
proceeds of the State excise tax of four cents per gallon is distributed by
formula to local governments. The first two cents (described as the
Constitutional Gas Tax) are primarily pledged for each county's debt service
requirements, with any remaining balance deposited into the county's
transportation trust fund. The remaining two cents of the excise tax (described
as the County and Municipal Gas Taxes) are part of the State Revenue Sharing
Program. Proceeds from the SCETS tax are, to the maximum extent possible,
expended on road projects in the counties in which the revenues are derived.
Local option gas taxes of one to 11 cents per net gallon, and the so-called
"ninth cent fuel tax" of one cent per net gallon, of motor fuel may be levied by
counties, for use by local governments for transportation expenditures. Local
Option Gas Tax revenues may be pledged for payment of bonds issued by the local
government or the Division of Bond Finance on behalf of local governments to
fund transportation capital improvements.

  Alcoholic beverage tax and license revenues totalled $523.3 million
(estimated) in the State fiscal year ended June 30, 2001, a 6% decrease from the
prior fiscal year. The receipts of corporate income tax for the State fiscal
year ended June 30, 2001 were $1,344.8 million (estimated), a decrease of 4.4%
over the prior fiscal year. In November 1986, the voters of the State approved a
constitutional amendment to allow the State to operate a lottery, the proceeds
of which are required to be applied as follows: 50% to be returned to the public
as prizes, at least 38% to be deposited in the Educational Enhancement Trust
(for public education), and no more than 12% to be spent on the administrative
cost of operating the lottery.

  The State Constitution does not permit a personal income tax. An amendment to
the State Constitution would be required to impose a personal income tax in the
State.

  LOCAL GOVERNMENT REVENUE SOURCES. County and municipal governments in Florida
depend primarily upon ad valorem property taxes, and sales, motor fuels and
other local excise taxes and miscellaneous revenue sources, including revenues
from utilities services. Florida school districts derive substantially all of
their revenues from local property taxes. The overall levels of revenues from
these sources is in part dependent upon the local, state and national economy.
Local government obligations held by the Fund may constitute general obligations
or may be special obligations payable solely from one or more specified revenue
sources. The ability of the local governments to repay their obligations on a
timely basis will be dependent upon the continued strength of the revenues
pledged and of the overall fiscal status of the local government.

  STATE CONSTITUTIONAL AMENDMENT LIMITING STATE REVENUES. An amendment to the
Constitution of the State of Florida was approved by the voters of the State of
Florida at the November 1994 general election. This amendment limits the amount
of taxes, fees, licenses and charges imposed by the State Legislature and
collected during any fiscal year to the amount of revenues allowed for the prior
fiscal year, plus an adjustment for growth. Growth is defined as the amount
equal to the average annual rate of growth in Florida personal income over the
most recent twenty quarters times the state revenues allowed for the prior
fiscal year. The revenues allowed for any fiscal year could be increased by a
two-thirds vote of the Legislature. The limit was

                                       B-11


effective in the fiscal year 1995-1996. Excess revenues generated will initially
be deposited in the budget stabilization fund until it is fully funded; any
additional excess revenues will then be refunded to taxpayers. This amendment
could limit the amount of actual revenues from which the State of Florida could
appropriate funds, including funds appropriated to local governments. It is
unclear at this point what effect, if any, this amendment would have on local
government debt obligations payable from state revenues which may be subject to
this amendment, such as state revenue sharing moneys or other state revenues
distributed to local governments. Certain State of Florida debt obligations,
which are not by their terms subject to appropriation, should not be affected,
depending upon the language of the legislation authorizing the issuance of such
obligations.

STATE REVENUES SHORTFALL AND BUDGET REDUCTIONS

  RECENT FINANCIAL DEVELOPMENTS. The State's general revenue collections were
approximately $130 million less than expected for the fiscal year ended June 30,
2001, or 0.7% of total expected general revenue of $19.3 billion for such
period. In anticipation of continued revenue weakness, only 24% of the budget
authority for state operations funded by general revenue was released for each
of the first two quarters of the current fiscal year.

  Revised general revenue estimates for the current fiscal year were released on
September 13, 2001. The forecast reduced general revenue tax estimates by $673.2
million for the 2001-02 fiscal year. Reductions in the general revenue tax
estimates resulted from the impact of a slowing national economy.

  As a result of the terrorist attacks on New York City and Washington, D.C., a
Consensus Estimating Conference for General Revenues was held October 15, 2001,
to revise the general revenue estimates released on September 13. The new
estimates of general revenue collections for the current fiscal year were
further reduced by $644.3 million; when combined with the September 13
reduction, this amounts to $1,317.5 less than the original estimate used to
develop this year's appropriations, a 6.6% reduction. This brings general fund
revenues available for appropriation in the current fiscal year to $19,361.7
million, which approximates the amount of general revenue expended on
appropriations in the previous fiscal year ($19,245.2 million.) The October 15
Conference also reduced the general revenue estimate for the 2002-03 fiscal year
by $783.5 million, which, when added to the September 13 reduction, brings the
total estimated general revenue available for appropriation in the fiscal year
to $19,595.2 million.

  With regard to the combined General Revenue/Working Capital Fund fiscal
position for the current fiscal year, the new estimate, when combined with other
funds available, left a year-end projected budget shortfall of $928.5 million.
This did not take into account reserve funds of $940.9 million in the Budget
Stabilization Fund.

  The Governor and Comptroller have a statutory duty to ensure that no deficit
occurs in any State fund. The expected shortfall in the General Revenue Fund
requires the State's budget to be reduced, or for moneys in the Budget
Stabilization Fund or other available funds to be applied to cover the shortfall
or a combination of these alternatives. Due to the size of the projected budget
shortfall, the legislature was required to address the expected budget
shortfall.

  At a special session of the Florida Legislature concluded on December 6, 2001,
the Legislature passed an appropriations bill to address the expected budget
shortfall and revise the State's budget for fiscal year ending June 30, 2002.
The revised budget uses a combination of spending reductions, deferral of
intangible tax relief and transfers or moneys in trust funds and the Working
Capital Fund to balance the State's budget as required by section 216.221,
Florida Statutes.

  The appropriations bill, which contains the revisions to the State budget,
includes spending reductions totalling $722 million. The revised budget also
uses $104 million from the Working Capital Fund and $383 million from trust
funds to mitigate the budget impact of the expected $1.3 billion revenue
shortfall (Senate Bill 2-C, Chapter 2001-367, Laws of Florida). Lastly, the
appropriations bill defers the intangibles tax relief until July 1, 2003, adding
an estimated $128 million to the current year's budget. The foregoing budgetary
items total $1.34 billion and leave the State with a Working Capital Fund
balance estimated to be approximately $300 million at the end of the current
fiscal year. Additionally, the State's revised budget uses none of the $940
million of reserves maintained in the Budget Stabilization Fund.

                                       B-12


  No further action by the Legislature on the State budget is expected. The next
time the Legislature is expected to consider the State budget is during the
regular legislative session commencing on January 22, 2002, at which time the
Legislature will begin formulating the budget for the 2002-03 fiscal year.

  The declining economic conditions in the nation and the state have affected
local governments as well. In particular, sales tax and tourist development tax
receipts are expected to be less than projected for the current fiscal year.
Some localities are more susceptible to economic downturns than others.

  ESTIMATES ARE SUBJECT TO RISK AND UNCERTAINTIES WHICH MAY AFFECT ACTUAL
REVENUE COLLECTIONS AND CAUSE RESULTS TO DIFFER MATERIALLY FROM THOSE STATED. NO
ASSURANCE IS GIVEN THAT ACTUAL REVENUE IMPACT WILL NOT DIFFER MATERIALLY FROM
THE ESTIMATES PROVIDED.

  OTHER FACTORS. Florida will continue to face enormous spending pressures well
into the future. The large number of elderly residents will continue to demand
health services, an area where cost escalation is significant, and the constant
influx of people to Florida will continue to place sizable pressure on the State
for infrastructure needs.

  The value of Florida municipal instruments may also be affected by general
conditions in the money markets or the municipal bond markets, the levels of
federal income tax rates, the supply of tax-exempt bonds, the credit quality and
rating of the issues and perceptions with respect to the level of interest
rates.

  There can be no assurance that there will not be a further decline in economic
conditions or that particular Florida municipal securities in the portfolio of
the Fund will not be adversely affected by any such changes.

"WHEN-ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS

  The Fund may also purchase and sell securities on a "when-issued" and "delayed
delivery" basis. No income accrues to the Fund on securities in connection with
such transactions prior to the date the Fund actually takes delivery of such
securities. These transactions are subject to market fluctuation; the value of
the securities at delivery may be more or less than their purchase price, and
yields generally available on securities when delivery occurs may be higher or
lower than yields on the 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 cash or liquid
securities having an aggregate value equal to the amount of such purchase
commitments until payment is made. The Fund will make commitments to purchase
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.

PORTFOLIO TURNOVER

  The Fund's 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.

ILLIQUID SECURITIES

  The Fund may invest up to 15% of its net assets in illiquid securities, which
includes securities that are not readily marketable, repurchase agreements which
have a maturity of longer than seven days and generally includes securities that
are restricted from sale to the public without registration under the Securities
Act of 1933, as amended (the "1933 Act"). The sale of such securities often
requires more time and results in higher brokerage charges or dealer discounts
and other selling expenses than does the sale of liquid securities trading on
national securities exchanges or in the over-the-counter markets. Restricted
securities are often purchased at a discount from the market price of
unrestricted securities of the same issuer reflecting the fact that such
                                       B-13


securities may not be readily marketable without some time delay. Investments in
securities for which market quotations are not readily available are valued at
their fair value as determined in good faith by the Adviser in accordance with
procedures approved by the Fund's Board of Trustees. Ordinarily, the Fund would
invest in restricted securities only when it receives the issuer's commitment to
register the securities without expense to the Fund. However, registration and
underwriting expenses (which typically range from 7% to 15% of the gross
proceeds of the securities sold) may be paid by the Fund. Restricted securities
which can be offered and sold to qualified institutional buyers under Rule 144A
under the 1933 Act ("144A Securities") and are determined to be liquid under
guidelines adopted by and subject to the supervision of the Fund's Board of
Trustees are not subject to the limitation on illiquid securities. Such 144A
Securities are subject to monitoring and may become illiquid to the extent
qualified institutional buyers become, for a time, uninterested in purchasing
such securities. Factors used to determine whether 144A Securities are liquid
include, among other things, a security's trading history, the availability of
reliable pricing information, the number of dealers making quotes or making a
market in such security and the number of potential purchasers in the market for
such security. For purposes hereof, investments by the Fund in securities of
other investment companies will not be considered investments in restricted
securities to the extent permitted by (i) the 1940 Act, as amended from time to
time, (ii) the rules and regulations promulgated by the SEC under the 1940 Act,
as amended from time to time, or (iii) an exemption or other relief (such as "no
action" letters issued by the staff of the SEC interpreting or providing
guidance on the 1940 Act or regulations thereunder) from the provisions of the
1940 Act, as amended from time to time.

NON-DIVERSIFICATION

  The Fund is a "non-diversified" investment company, which means the Fund is
not limited in the proportion of its assets that may be invested in the
securities of a single issuer. However, the Fund intends to conduct its
operations so as to qualify as a "regulated investment company" for purposes of
the Code. If the Fund qualifies as a regulated investment company under the
Code, it will be relieved of any liability for federal income tax to the extent
its earnings are distributed to shareholders. To qualify, among other
requirements, the Fund must limit its investments so that, at the close of each
quarter of the Fund's taxable year, (i) not more than 25% of the market value of
the Fund's total assets is invested in securities of a single issuer (other than
the U.S. government, its agencies and instrumentalities or other regulated
investment companies) or of two or more issuers which the Fund controls and
which are determined to be in the same or similar, or related, trades or
businesses, and (ii) at least 50% of the market value of its total assets is
invested in cash, cash items, securities of the U.S. government, its agencies
and instrumentalities, securities of other regulated investment companies and
other securities limited in respect of any one issuer to an amount not greater
than 5% of the market value of the Fund's total assets and not more than 10% of
the outstanding voting securities of such issuer. Since the Fund, as a
non-diversified investment company, may invest in a smaller number of individual
issuers than a diversified investment company, an investment in the Fund may,
under certain circumstances, present greater risks to an investor than an
investment in a diversified company.

                             STRATEGIC TRANSACTIONS

  The Fund may, but is not required to, use various Strategic Transactions (as
defined in the Prospectus) to earn income, facilitate portfolio management and
mitigate risks. Techniques and instruments may change over time as new
instruments and strategies are developed or regulatory changes occur. Although
the Adviser seeks to use such transactions to further the Fund's investment
objective, no assurance can be given that the use of these transactions will
achieve this result.

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."

                                       B-14


  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 futures
contract, index or other instrument might be intended to protect the Fund
against an increase in the price of the underlying instrument that it intends to
purchase in the future by fixing the price at which it may purchase such
instrument. An American style put or call option may be exercised at any time
during the option period while a European style put or call option may be
exercised only upon expiration or during a fixed period prior thereto. The Fund
is authorized to purchase and sell exchange listed options and over-the-counter
options ("OTC options"). Exchange listed options are issued by a regulated
intermediary such as the Options Clearing Corporation ("OCC"), which guarantees
the performance of the obligations of the parties to such options. The
discussion below uses the OCC as a paradigm, but is also applicable to other
financial intermediaries.

  With certain exceptions, OCC issued and exchange listed options generally
settle by physical delivery of the underlying security or currency, although in
the future cash settlement may become available. Index options and Eurodollar
instruments are cash settled for the net amount, if any, by which the option is
"in-the-money" (i.e., where the value of the underlying instrument exceeds, in
the case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed options are closed by entering into
offsetting purchase or sale transactions that do not result in ownership of the
new option.

  The Fund's ability to close out its position as a purchaser or seller of an
OCC or exchange listed put or call option is dependent, in part, upon the
liquidity of the option market. Among the possible reasons for the absence of a
liquid option market on an exchange are: (i) insufficient trading interest in
certain options; (ii) restrictions on transactions imposed by an exchange; (iii)
trading halts, suspensions or other restrictions imposed with respect to
particular classes or series of options or underlying securities including
reaching daily price limits; (iv) interruption of the normal operations of the
OCC or an exchange; (v) inadequacy of the facilities of an exchange or OCC to
handle current trading volume; or (vi) a decision by one or more exchanges to
discontinue the trading of options (or a particular class or series of options),
in which event the relevant market for that option on that exchange would cease
to exist, although outstanding options on that exchange would generally continue
to be exercisable in accordance with their terms.

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

  OTC options are purchased from or sold to securities dealers, financial
institutions or other parties ("Counterparties") through direct bilateral
agreement with the Counterparty. In contrast to exchange listed options, which
generally have standardized terms and performance mechanics, all the terms of an
OTC option, including such terms as method of settlement, term, exercise price,
premium, guarantees and security, are set by negotiation of the parties. The
Fund will only enter into OTC options that have a buy-back provision permitting
the Fund to require the Counterparty to close the option 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

                                       B-15


Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be satisfied.
The Fund will engage in OTC option transactions only with United States
government securities dealers recognized by the Federal Reserve Bank of New York
as "primary dealers", or broker-dealers, domestic or foreign banks or other
financial institutions which have received (or the guarantors of the obligation
of which have received) a short-term credit rating of "A-1" from S&P or "P-1"
from Moody's or an equivalent rating from any other NRSRO. The staff of the SEC
currently takes the position that, in general, OTC options on securities (other
than U.S. government securities) purchased by the Fund, and portfolio securities
"covering" the amount of the Fund's obligation pursuant to an OTC option sold by
it (the cost of the sell-back plus the in-the-money amount, if any) are
illiquid, and are subject to the Fund's limitation on illiquid securities
described herein.

  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, corporate debt securities that are traded on securities exchanges
and in the over-the-counter markets and related futures contracts. All calls
sold by the Fund must be "covered" (i.e., the Fund must own the securities or
futures contract subject to the call) or must meet the asset segregation
requirements described below as long as the call is outstanding. Even though the
Fund will receive the option premium to help protect it against loss, a call
sold by the Fund exposes the Fund during the term of the option to possible loss
of opportunity to realize appreciation in the market price of the underlying
security or instrument and may require the Fund to hold a security or instrument
which it might otherwise have sold. In the event of exercise of a call option
sold by the Fund with respect to securities not owned by the Fund, the Fund may
be required to acquire the underlying security at a disadvantageous price to
satisfy its obligation with respect to the call option.

  The Fund may purchase and sell put options on securities including U.S.
Treasury and agency securities, municipal obligations, mortgage-backed
securities and corporate debt securities (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 contracts and options on futures contracts. 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.

FUTURES CONTRACTS

  The Fund may enter into financial futures contracts or purchase or sell put
and call options on futures contracts as a hedge against anticipated interest
rate or fixed-income market changes, for duration management and for risk
management purposes. Futures contracts 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
contracts 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 contracts 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 contracts and options on futures contracts
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 on a futures contract
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

                                       B-16


(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 contracts position just
as it would for any position. Futures contracts and options on futures contracts
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 an option on a futures
contract (except for closing transactions) for other than bona fide hedging
purposes if, immediately thereafter, the sum of the amount of its initial margin
and premiums on open futures contracts and options on futures contracts 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 on
futures contracts 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 contracts transactions and multiple interest rate
transactions and any combination of futures contracts, 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

                                       B-17


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. A
large number of banks and investment banking firms act 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 cash and liquid securities to the extent Fund obligations are
not otherwise "covered" through ownership of the underlying security, financial
instrument or currency. In general, either the full amount of any obligation by
the Fund to pay or deliver securities or assets must be covered at all times by
the securities, instruments or currency required to be delivered, or, subject to
any regulatory restrictions, an amount of cash or liquid securities at least
equal to the current amount of the obligation must be segregated. The segregated
assets cannot be sold or transferred unless equivalent assets are substituted in
their place or it is no longer necessary to segregate. 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 cash and liquid securities sufficient
to purchase and deliver the securities if the call is exercised. A call option
sold by the Fund on an index will require the Fund to own portfolio securities
which correlate with the index or to segregate cash and liquid securities equal
to the excess of the index value over the exercise price on a current basis. A
put option written by the Fund requires the Fund to segregate cash and liquid
securities equal to the exercise price.

  OTC options entered into by the Fund, including those on securities, financial
instruments or indices and OCC issued and exchange listed index options, will
generally provide for cash settlement. As a result, when the Fund sells these
instruments it will only segregate an amount of cash and liquid securities 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 and liquid securities 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 cash and liquid securities 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 on a futures contract, the Fund
must deposit initial margin and possible daily variation margin in addition to
segregating cash and liquid securities 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.

                                       B-18


  With respect to swaps, the Fund will accrue the net amount of the excess, if
any, of its obligations over its entitlements with respect to each swap on a
daily basis and will segregate an amount of cash or liquid securities having a
value equal to the accrued excess. Caps, floors and collars require segregation
of cash and liquid securities 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 cash and
liquid securities, 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 cash and liquid
securities if the Fund held a futures contract or forward contract, it could
purchase a put option on the same futures contract 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, cash and
liquid securities equal to any remaining obligation would need to be segregated.

  The Fund's activities involving Strategic Transactions may be limited by the
requirements of the Code for qualification as a regulated investment company.

                            INVESTMENT RESTRICTIONS

  The Fund has adopted the following fundamental investment restrictions which
may not be changed without shareholder approval by the vote of a majority of its
outstanding voting securities, which is defined by the 1940 Act as the lesser of
(i) 67% or more of the Fund's voting securities present at a meeting, if the
holders of more than 50% of the Fund's outstanding voting securities are present
or represented by proxy; or (ii) more than 50% of the Fund's outstanding voting
securities. The percentage limitations contained in the restrictions and
policies set forth herein apply at the time of purchase of securities. With
respect to the limitations on illiquid securities and borrowings, the percentage
limitations apply at the time of purchase and on an ongoing basis. These
restrictions provide that the Fund shall not:

   1. Invest more than 25% of its assets in a single industry; however, 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, and except that the Fund may purchase securities of other
      investment companies to the extent permitted by (i) the 1940 Act, as
      amended from time to time, (ii) the rules and regulations promulgated by
      the SEC under the 1940 Act, as amended from time to time, or (iii) an
      exemption or other relief from the provisions of the 1940 Act, as amended
      from time to time.

   2. Borrow money, except from banks for temporary purposes and then in amounts
      not in excess of 5% of the total asset value of the Fund, or mortgage,
      pledge, or hypothecate any assets except in connection with a borrowing
      and in amounts not in excess of 10% of the total asset value of the Fund.
      Borrowings may not be made for investment leverage, but only to enable the
      Fund to satisfy redemption requests where liquidation of portfolio
      securities is considered disadvantageous or inconvenient. In this
      connection, the Fund will not purchase portfolio securities during any
      period that such borrowings exceed 5% of the total asset value of the
      Fund. Notwithstanding this investment restriction, the Fund may enter into
      when-issued and delayed delivery transactions.

   3. Make loans of money or property to any person, except to the extent the
      securities in which the Fund may invest are considered to be loans and
      except that the Fund may lend money or property in connection with
      maintenance of the value of, or the Fund's interest with respect to, the
      securities owned by the Fund.

   4. Buy any securities "on margin." Neither the deposit of initial or
      maintenance margin in connection with hedging transactions nor short term
      credits as may be necessary for the clearance of transactions is
      considered the purchase of a security on margin.

                                       B-19


   5. Sell any securities "short," write, purchase or sell puts, calls or
      combinations thereof, or purchase or sell interest rate or other financial
      futures contracts or index contracts or options on futures contracts,
      except in connection with Strategic Transactions in accordance with the
      requirements of the SEC and the Commodity Futures Trading Commission.

   6. Act as an underwriter of securities, except to the extent the Fund may be
      deemed to be an underwriter in connection with the sale of securities held
      in its portfolio.

   7. Make investments for the purpose of exercising control or participation in
      management, except to the extent that exercise by the Fund of its rights
      under agreements related to securities owned by the Fund would be deemed
      to constitute such control or participation, and except that the Fund may
      purchase securities of other investment companies to the extent permitted
      by (i) the 1940 Act, as amended from time to time, (ii) the rules and
      regulations promulgated by the SEC under the 1940 Act, as amended from
      time to time, or (iii) an exemption or other relief from the provisions of
      the 1940 Act, as amended from time to time.

   8. Invest in securities issued by other investment companies except as part
      of a merger, reorganization or other acquisition and except that the Fund
      may purchase securities of other investment companies to the extent
      permitted by (i) the 1940 Act, as amended from time to time, (ii) the
      rules and regulations promulgated by the SEC under the 1940 Act, as
      amended from time to time, or (iii) an exemption or other relief from the
      provisions of the 1940 Act, as amended from time to time.

   9. Invest in oil, gas or mineral leases or in equity interests in oil, gas,
      or other mineral exploration or development programs, except pursuant to
      the exercise by the Fund of its rights under agreements relating to
      municipal securities.

  10. Purchase or sell real estate, commodities or commodity contracts, except
      to the extent the securities the Fund may invest in are considered to be
      interest in real estate, commodities or commodity contracts or to the
      extent the Fund exercises its rights under agreements relating to such
      securities (in which case the Fund may own, hold, foreclose, liquidate or
      otherwise dispose of real estate acquired as a result of a default on a
      mortgage), and except to the extent that Strategic Transactions the Fund
      may engage in are considered to be commodities or commodities contracts.

         DESCRIPTION OF INSURANCE COMPANY CLAIMS PAYING ABILITY RATINGS

RATINGS OF INSURANCE COMPANY CLAIMS-PAYING ABILITY

  The claims-paying ability of insurance companies is rated by S&P and Moody's.
Descriptions of these ratings are set forth below:

DESCRIPTION OF S&P'S RATINGS OF INSURANCE COMPANY CLAIMS-PAYING ABILITY

  A S&P Insurer Financial Strength Rating is a current opinion of the financial
security characteristics of an insurance organization with respect to its
ability to pay under its insurance policies and contracts in accordance with
their terms. Insurer Financial Strength Ratings are also assigned to health
maintenance organizations and similar health plans with respect to their ability
to pay under their policies and contracts in accordance with their terms.

  This opinion is not specific to any particular policy or contract, nor does it
address the suitability of a particular policy or contract for a specific
purpose or purchaser. Furthermore, the opinion does not take into account
deductibles, surrender or cancellation penalties, timeliness of payment, nor the
likelihood of the use of a defense such as fraud to deny claims. For
organizations with cross-border or multinational operations, including those
conducted by subsidiaries or branch offices, the ratings do not take into
account potential that may exist for foreign exchange restrictions to prevent
financial obligations from being met.

  Insurer Financial Strength Ratings are based on information furnished by rated
organizations or obtained by Standard & Poor's from other sources it considers
reliable. S&P does not perform an audit in connection with

                                       B-20


any rating and may on occasion rely on unaudited financial information. Ratings
may be changed, suspended, or withdrawn as a result of changes in, or
unavailability of such information or based on other circumstances.

  Insurer Financial Strength Ratings do not refer to an organization's ability
to meet nonpolicy (i.e., debt) obligations. Assignment of ratings to debt issued
by insurers or to debt issues that are fully or partially supported by insurance
policies, contracts, or guarantees is a separate process from the determination
of Insurer Financial Strength Ratings, and follows procedures consistent with
issue credit rating definitions and practices. Insurer Financial Strength
Ratings are not a recommendation to purchase or discontinue any policy or
contract issued by an insurer or to buy, hold, or sell any security issued by an
insurer. A rating is not a guaranty of an insurer's financial strength or
security.

  An insurer rated "BBB" or higher is regarded as having financial security
characteristics that outweigh any vulnerabilities, and is highly likely to have
the ability to meet financial commitments.

  AAA. An insurer rated "AAA" has EXTREMELY STRONG financial security
characteristics. "AAA" is the highest Insurer Financial Strength Rating assigned
by S&P.

  AA. An insurer rated "AA" has VERY STRONG financial security characteristics,
differing only slightly from those rated higher.

  A. An insurer rated "A" has STRONG financial security characteristics, but is
somewhat more likely to be affected by adverse business conditions than are
insurers with higher ratings.

  BBB. An insurer rated "BBB" has GOOD financial security characteristics, but
is more likely to be affected by adverse business conditions than are higher
rated insurers. An insurer rated "BB" or lower is regarded as having vulnerable
characteristics that may outweigh its strengths. "BB" indicates the least degree
of vulnerability within the range; "CC" the highest.

  Ratings from "AA" to "CCC" may be modified by the addition of a plus (+) or
minus (-) sign to show relative standing within the major rating categories.
CreditWatch highlights the potential direction of a rating, focusing on
identifiable events and short-term trends that cause ratings to be placed under
special surveillance by S&P. The events may include mergers, recapitalizations,
voter referenda, regulatory actions, or anticipated operating developments.
Ratings appear on CreditWatch when such an event or a deviation from an expected
trend occurs and additional information is needed to evaluate the rating. A
listing, however, does not mean a rating change is inevitable, and whenever
possible, a range of alternative ratings will be shown.

  CreditWatch is not intended to include all ratings under review, and rating
changes may occur without the ratings having first appeared on CreditWatch. The
"positive" designation means that a rating may be raised; "negative" means that
a rating may be lowered; "developing" means that a rating may be raised, lowered
or affirmed.

  "pi" Ratings, denoted with a "pi" subscript, are Insurer Financial Strength
Ratings based on an analysis of published financial information and additional
information in the public domain. They do not reflect in-depth meetings with an
insurer's management and are therefore based on less comprehensive information
than ratings without a "pi" subscript. "pi" ratings are reviewed annually based
on a new year's financial statements, but may be reviewed on an interim basis if
a major event that may affect an insurer's financial security occurs. Ratings
with a "pi" subscript are not subject to potential CreditWatch listings and are
not modified with "+" or "-" designations.

DESCRIPTION OF MOODY'S RATINGS OF INSURANCE COMPANY CLAIMS-PAYING ABILITY

  Moody's Insurance Financial Strength Ratings are opinions of the ability of
insurance companies to repay punctually senior policyholder claims and
obligations. Specific obligations are considered unrated unless they are
individually rated because the standing of a particular insurance obligation
would depend on an assessment of its relative standing under those laws
governing both the obligation and the insurance company.

  It is important to note that Moody's makes no representation that rated
insurance company obligations are exempt from registration under the U.S.
Securities Act of 1933 or issued in conformity with any other

                                       B-21


applicable law or regulation. Nor does Moody's represent that any specific
insurance company obligation is legally enforceable or a valid senior obligation
of a rated issuer.

  Insurance Financial Strength Ratings shown in connection with
property/casualty groups represent the ratings of individual companies within
those groups, as displayed in Moody's insurance industry ratings list. The
rating of an individual property/casualty company may be based on the benefit of
its participation in an intercompany pooling agreement. Pooling agreements may
or may not provide for continuation of in-force policyholder obligations by pool
members in the event that the property/casualty insurer is sold to a third party
or otherwise removed from the pooling agreement.

  Moody's assumes in these ratings that the pooling agreement will not be
modified by the members of the pool to reduce the benefits of pool
participating, and that the insurer will remain in the pool. Moody's makes no
representation or warranty that such pooling agreement will not be modified over
time, nor does Moody's opine on the probability that the rated entity may be
sold or otherwise removed from the pooling agreement.

  Moody's rating symbols for Insurance Financial Strength Ratings are identical
to those used to show the credit quality of bonds. These rating gradations
provide investors with a simple system to measure an insurance company's ability
to meet its senior policyholder claims and obligations.

  Rating gradations are broken down into nine distinct symbols, each symbol
representing a group of ratings in which the quality characteristics are broadly
the same. These symbols, which comprise two distinct rating groups of strong and
weak companies, range from those used to designate the greatest financial
strength (i.e., highest investment quality) to those denoting the least
financial strength (i.e., lowest investment quality).

  Numeric modifiers are used to refer to the ranking within the group -- with 1
being the highest and 3 being the lowest. However, the financial strength of
companies within a generic rating symbol (Aa, for example) is broadly the same.

  AAA. Insurance companies rated Aaa offer exceptional financial security. While
the financial strength of these companies is likely to change, such changes as
can be visualized are most unlikely to impair their fundamentally strong
position.

  AA. Insurance companies rated Aa offer excellent financial security. Together
with the Aaa group, they constitute what are generally known as high-grade
companies. They are rated lower than Aaa companies because long-term risks
appear somewhat larger.

  A. Insurance companies rated A offer good financial security. However,
elements may be present which suggest a susceptibility to impairment sometime in
the future.

  BAA. Insurance companies rated Baa offer adequate financial security. However,
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time.

</Table>

  Each trustee/director holds the same position with each of the funds in the
Fund Complex. As of the date of this Statement of Additional Information, there
are 61 operating funds in the Fund Complex. Each trustee/director who is not an
affiliated person of Van Kampen Investments, the Advisers or the Distributor
(each a "Non-Affiliated Trustee") is compensated by an annual retainer and
meeting fees for services to the funds in the Fund Complex. Each fund in the
Fund Complex provides a deferred compensation plan to its Non-Affiliated
Trustees that allows trustees/directors to defer receipt of their compensation
and earn a return on such deferred amounts. Deferring compensation has the
economic effect as if the Non-Affiliated Trustee reinvested his or her
compensation into the funds. Each fund in the Fund Complex provides a retirement
plan

                                       B-27


to its Non-Affiliated Trustees that provides Non-Affiliated Trustees with
compensation after retirement, provided that certain eligibility requirements
are met as more fully described below.

  The compensation of each Non-Affiliated Trustee includes an annual retainer in
an amount equal to $50,000 per calendar year, due in four quarterly installments
on the first business day of each quarter. Payment of the annual retainer is
allocated among the funds in the Fund Complex on the basis of the relative net
assets of each fund as of the last business day of the preceding calendar
quarter. The compensation of each Non-Affiliated Trustee includes a per meeting
fee from each fund in the Fund Complex in the amount of $200 per quarterly or
special meeting attended by the Non-Affiliated Trustee, due on the date of the
meeting, plus reasonable expenses incurred by the Non-Affiliated Trustee in
connection with his or her services as a trustee/director, provided that no
compensation will be paid in connection with certain telephonic special
meetings.

  Under the deferred compensation plan, each Non-Affiliated Trustee generally
can elect to defer receipt of all or a portion of the compensation earned by
such Non-Affiliated Trustee until retirement. Amounts deferred are retained by
the Fund and earn a rate of return determined by reference to the return on the
common shares of such Fund or other funds in the Fund Complex as selected by the
respective Non-Affiliated Trustee, with the same economic effect as if such
Non-Affiliated Trustee had invested in one or more funds in the Fund Complex. To
the extent permitted by the 1940 Act, the Fund may invest in securities of those
funds selected by the Non-Affiliated Trustees in order to match the deferred
compensation obligation. The deferred compensation plan is not funded and
obligations thereunder represent general unsecured claims against the general
assets of the Fund.

  Under the retirement plan, a Non-Affiliated Trustee who is receiving
compensation from such Fund prior to such Non-Affiliated Trustee's retirement,
has at least 10 years of service (including years of service prior to adoption
of the retirement plan) and retires at or after attaining the age of 60, is
eligible to receive a retirement benefit equal to $2,500 per year for each of
the ten years following such retirement from such Fund. Non-Affiliated Trustees
retiring prior to the age of 60 or with fewer than 10 years but more than 5
years of service may receive reduced retirement benefits from such Fund. Each
trustee/director has served as a member of the Board of Trustees of the Fund
since he or she was first appointed or elected in the year set forth below. The
retirement plan contains a Fund Complex retirement benefit cap of $60,000 per
year.

  Additional information regarding compensation and benefits for trustees is set
forth below for the periods described in the notes accompanying the table.

(1) Trustees not eligible for compensation are not included in the Compensation
    Table. Fernando Sisto retired as a member of the Board of Trustees for the
    Fund and other funds in the Fund Complex on December 31, 2000.

(2) The amounts shown in this column represent the aggregate compensation before
    deferral with respect to the Trust's fiscal year ended September 30, 2001.
    The detail of aggregate compensation before deferral for each series,
    including the Fund, is shown in Table A below. The detail of amounts
    deferred for each series,

                                       B-28


    including the Fund, is shown in Table B below. Amounts deferred are retained
    by the Fund and earn a rate of return determined by reference to either the
    return on the common shares of the Fund or other funds in the Fund Complex
    as selected by the respective Non-Affiliated Trustee, with the same economic
    effect as if such Non-Affiliated Trustee had invested in one or more funds
    in the Fund Complex. To the extent permitted by the 1940 Act, each fund may
    invest in securities of those funds selected by the Non-Affiliated Trustees
    in order to match the deferred compensation obligation. The detail of
    cumulative deferred compensation (including interest) owed to trustees,
    including former trustees, by each series, including the Fund, is shown in
    Table C below. The deferred compensation plan is described above the
    Compensation Table.

(3) The amounts shown in this column represent the sum of the retirement
    benefits accrued by the operating investment companies in the Fund Complex
    for each of the trustees for the funds' respective fiscal years ended in
    2001. The retirement plan is described above the Compensation Table.

(4) For each trustee, this is the sum of the estimated maximum annual benefits
    payable by the funds in the Fund Complex for each year of the 10-year period
    commencing in the year of such trustee's anticipated retirement. The
    retirement plan is described above the Compensation Table. Each
    Non-Affiliated Trustee of the Board of Trustees has served as a member of
    the Board of Trustees since he or she was first appointed or elected in the
    year set forth in Table D below.

(5) The amounts shown in this column represent the aggregate compensation paid
    by all of the funds in the Fund Complex as of December 31, 2001 before
    deferral by the trustees under the deferred compensation plan. Because the
    funds in the Fund Complex have different fiscal year ends, the amounts shown
    in this column are presented on a calendar year basis. Certain trustees
    deferred all or a portion of their aggregate compensation from the Fund
    Complex during the calendar year ended December 31, 2001. The deferred
    compensation earns a rate of return determined by reference to the return on
    the shares of the funds in the Fund Complex as selected by the respective
    Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, the Fund may invest in
    securities of those investment companies selected by the Non-Affiliated
    Trustees in order to match the deferred compensation obligation. The
    Advisers and their affiliates also serve as investment adviser for other
    investment companies; however, with the exception of Mr. Whalen, the
    Non-Affiliated Trustees were not trustees of such investment companies.
    Combining the Fund Complex with other investment companies advised by the
    Advisers and their affiliates, Mr. Whalen earned Total Compensation of
    $276,650 during the calendar year ended December 31, 2001.

                                                                         TABLE A

  The Fund, the Adviser and the Distributor have adopted a Code of Ethics (the
"Code of Ethics") that sets forth general and specific standards relating to the
securities trading activities of their employees. The Code of Ethics does not
prohibit employees from acquiring securities that may be purchased or held by
the Fund, but is intended to ensure that all employees conduct their personal
transactions in a manner that does not interfere with the portfolio transactions
of the Fund or other Van Kampen funds, or that such employees take unfair
advantage of their relationship with the Fund. Among other things, the Code of
Ethics prohibits certain types of transactions absent prior approval, imposes
various trading restrictions (such as time periods during which personal
transactions may or may not be made) and requires quarterly reporting of
securities transactions and other reporting matters. All reportable securities
transactions and other required reports are to be reviewed by appropriate
personnel for compliance with the Code of Ethics. Additional restrictions apply
to portfolio managers, traders, research analysts and others who may have access
to nonpublic information about the trading activities of the Fund or other Van
Kampen funds or who otherwise are involved in the investment advisory process.
Exceptions to these and other provisions of the Code of Ethics may be granted in
particular circumstances after review by appropriate personnel.

     As of January 8, 2002, the trustees and officers of the Fund as a group
owned less than 1% of the shares of the Fund.

                         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 the Fund's assets, including the placing of
orders for the purchase and sale of portfolio securities. The Adviser obtains
and evaluates economic, statistical and financial information to formulate
strategy and implement the Fund's investment objective. The Adviser also
furnishes offices, necessary facilities and equipment, provides administrative
services to the Fund, renders periodic reports to the Fund's Board of Trustees
and permits its officers and employees to serve without compensation as trustees
of the Trust or officers of the Fund if elected to such positions. The Fund,
however, bears the cost of its day-to-day operations, including service fees,
distribution fees, custodian fees, legal and independent accountant fees, the
costs of reports and proxies to shareholders, compensation of trustees of the
Trust (other than those who are affiliated persons of the Adviser, Distributor
or Van Kampen Investments) and all other ordinary business expenses not
specifically assumed by the Adviser. The Advisory Agreement also provides that
the Adviser shall not be liable to the Fund for any error of judgment or of law,
or for any loss suffered by the Fund in connection with the matters to which the
Advisory Agreement relates, except a loss resulting from willful misfeasance,
bad faith, 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 Advisory Agreement.

  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 any jurisdiction in which the Fund's shares are qualified for
offer and sale (excluding any expenses permitted to be excluded from the
computation under applicable law or regulation), 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 Fund
monthly an amount sufficient to make up the deficiency, subject to readjustment
during the fiscal year.

  The Advisory Agreement may be continued from year to year if specifically
approved at least annually (a)(i) by the Fund's Board of Trustees or (ii) by a
vote of a majority of the Fund's outstanding voting securities and (b) by a 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.

                                OTHER AGREEMENTS

  ACCOUNTING SERVICES AGREEMENT.  The Fund has entered into an accounting
services agreement pursuant to which Advisory Corp. provides accounting services
to the Fund 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 pays all costs and expenses related to such services,
including all salary and related benefits of accounting personnel, as well as
the overhead and expenses of office space and the equipment necessary to render
such services. The Fund shares together with the other Van Kampen funds in the
cost of providing such services with 25% of such costs shared proportionately
based on the respective number of classes of securities issued per fund and the
remaining 75% of such costs based proportionately on the respective net assets
per fund.

  During the fiscal years ended September 30, 2001, 2000 and 1999, Advisory
Corp. received $22,900, $0 and $0, respectively, in accounting services fees
from the Fund.

                                       B-31


  LEGAL SERVICES AGREEMENT.  The Fund and certain other Van Kampen funds have
entered into legal services agreements pursuant to which Van Kampen Investments
provides legal services, including without limitation: accurate maintenance of
each fund's minute books and records, preparation and oversight of each fund's
regulatory reports and other information provided to shareholders, as well as
responding to day-to-day legal issues on behalf of the funds. Payment by the
funds for such services is made on a cost basis for the salary and
salary-related benefits, including but not limited to bonuses, group insurance
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 Investments. Of the total costs for legal
services provided to funds, 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.

  During the fiscal years ended September 30, 2001, 2000 and 1999, Van Kampen
Investments received $22,400, $0 and $0, respectively, in legal services fees
from the Fund.

                            DISTRIBUTION AND SERVICE

  The Distributor acts as the principal underwriter of the Fund's shares
pursuant to a written agreement (the "Distribution and Service Agreement"). The
Distributor has the exclusive right to distribute shares of the Fund through
authorized dealers on a continuous basis. 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 certain other costs including the cost of
supplemental sales literature and advertising. The Distribution and Service
Agreement is renewable from year to year if approved (a)(i) by the Fund's Board
of Trustees or (ii) by a vote of a majority of the Fund's outstanding voting
securities and (b) by a vote of a majority of Trustees who are not parties to
the Distribution and Service Agreement or interested persons of any party, by
votes cast in person at a meeting called for such purpose. The Distribution and
Service Agreement provides that it will terminate if assigned, and that it may
be terminated without penalty by either party on 90 days' written notice. Total
underwriting commissions on the sale of shares of the Fund for the last three
fiscal years are shown in the chart below.

- ---------------
* No sales charge is payable at the time of purchase on investments of $1
  million or more, although the Fund may impose a contingent deferred sales
  charge of 1.00% on certain redemptions made within one year of the purchase. A
  commission or transaction fee will be paid by the Distributor at the time of
  purchase directly out of the Distributor's assets (and not out of the Fund's
  assets) to authorized dealers who initiate and are responsible for purchases
  of $1 million or more computed on a percentage of the dollar value of such
  shares sold as follows: 1.00% on sales to $2 million, plus 0.80% on the next
  $1 million and 0.50% on the excess over $3 million. For single purchases of
  $20 million or more by an individual retail investor, the Distributor will
  pay, at the time of purchase and directly out of the Distributor's assets (and
  not out of the Fund's assets), a commission or transaction fee of 1.00% to
  authorized dealers who initiate and are responsible for such purchases. The
  commission or transaction fee of 1.00% will be computed on a percentage of the
  dollar value of such shares sold.

  With respect to sales of Class B Shares and Class C Shares of the Fund, a
commission or transaction fee generally will be paid by the Distributor at the
time of purchase directly out of the Distributor's assets (and not out of the
Fund's assets) to authorized dealers who initiate and are responsible for such
purchases computed based on a percentage of the dollar value of such shares sold
of 4.00% on Class B Shares and 1.00% on Class C Shares.

  Proceeds from any contingent deferred sales charge and any distribution fees
on Class B Shares and Class C Shares of the Fund are paid to the Distributor and
are used by the Distributor to defray its distribution related expenses in
connection with the sale of the Fund's shares, such as the payment to authorized
dealers for selling such shares. With respect to Class C Shares, the authorized
dealers generally are paid the ongoing commission and transaction fees of up to
0.75% of the average daily net assets of the Fund's Class C Shares annually
commencing in the second year after purchase.

  In addition to reallowances or commissions described above, the Distributor
may from time to time implement programs under which an authorized dealer's
sales force may be eligible to win nominal awards for certain sales efforts or
under which the Distributor will reallow to any authorized dealer 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 authorized dealer at the public offering price during such programs.
Also, the Distributor in its discretion may from time to time, pursuant to
objective criteria established by the Distributor, pay fees to, and sponsor
business seminars for, qualifying authorized dealers for certain services or
activities which are primarily intended to result in sales of shares of the Fund
or other Van Kampen funds. Fees may include payment for travel expenses,
including lodging, incurred in connection with trips taken by invited registered
representatives for meetings or seminars of a business nature. In some instances
additional compensation or promotional incentives may be offered to brokers,
dealers or financial intermediaries that have sold or may sell significant
amounts of shares during specified periods of time. The Distributor may provide
additional compensation to Edward D. Jones & Co. or an affiliate thereof based
on a combination of its quarterly sales of shares of the Fund and other Van
Kampen funds and increases in net assets of the Fund and other Van Kampen funds
over specified thresholds. All of the foregoing payments are made by the
Distributor out of its own assets. Such fees paid for such services and
activities with respect to the Fund will not exceed in the aggregate 1.25% of
the average total daily net assets of the Fund on an annual basis. These
programs will not change the price an investor will pay for shares or the amount
that a Fund will receive from such sale.

  The Fund has adopted a distribution plan (the "Distribution Plan") with
respect to each of its Class A Shares, Class B Shares and Class C Shares
pursuant to Rule 12b-1 under the 1940 Act. The Fund also adopted a service plan
(the "Service Plan") with respect to each of its Class A Shares, Class B Shares
and Class C Shares. The Distribution Plan and the Service Plan sometimes are
referred to herein as the "Plans." The Plans provide that the Fund may spend a
portion of the Fund's average daily net assets attributable to each such class
of shares in connection with distribution of the respective class of shares and
in connection with the provision of ongoing services to shareholders of such
class, respectively. The Distribution Plan and the Service Plan are being
implemented through the Distribution and Service Agreement with the Distributor
of each such class of the Fund's shares, sub-agreements between the Distributor
and members of the NASD who

                                       B-33


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."

  Certain financial intermediaries may be prohibited under law from providing
certain underwriting or distribution services. If a financial intermediary was
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 financial intermediary would result in any material adverse consequences
to the Fund.

  The Distributor must submit quarterly reports to the Board of Trustees of the
Trust, of which the Fund is a series, setting forth separately by class of
shares all amounts paid under the Distribution Plan and the purposes for which
such expenditures were made, together with such other information as from time
to time is reasonably requested by the Trustees. The Plans provide that they
will continue in full force and effect from year to year so long as such
continuance is specifically approved by a vote of the Trustees, and also by a
vote of the disinterested Trustees, cast in person at a meeting called for the
purpose of voting on the Plans. Each of the Plans may not be amended to increase
materially the amount to be spent for the services described therein with
respect to any 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 any 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 Class A Shares in any given year in which the Plans are in effect, the
Plans generally provide for the Fund to pay the Distributor the lesser of (i)
the amount of the Distributor's actual expenses incurred during such year less
any deferred sales charges (if any) it received during such year (the "actual
net expenses") or (ii) the distribution and service fees at the rates specified
in the Prospectus (the "plan fees"). Therefore, to the extent the Distributor's
actual net expenses in a given year are less than the plan fees for such year,
the Fund only pays the actual net expenses. Alternatively, to the extent the
Distributor's actual net expenses in a given year exceed the plan fees for such
year, the Fund only pays the plan fees for such year. For Class A Shares, there
is no carryover of any unreimbursed actual net expenses to succeeding years.

  The Plans for Class B Shares and Class C Shares are similar to the Plans for
Class A Shares, except that any actual net expenses which exceed plan fees for a
given year are carried forward and are eligible for payment in future years by
the Fund so long as the Plans remain in effect. Thus, for each of the Class B
Shares and Class C Shares, in any given year in which the Plans are in effect,
the Plans generally provide for the Fund to pay the Distributor the lesser of
(i) the applicable amount of the Distributor's actual net expenses incurred
during such year for such class of shares plus any actual net expenses from
prior years that are still unpaid by the Fund for such class of shares or (ii)
the applicable plan fees for such class of shares. Except as may be mandated by
applicable law, the Fund does not impose any limit with respect to the number of
years into the future that such unreimbursed actual net expenses may be carried
forward (on a Fund level basis). These unreimbursed actual net expenses may or
may not be recovered through plan fees or contingent deferred sales charges in
future years.

  Because of fluctuations in net asset value, the plan fees with respect to a
particular Class B Share or Class C Share may be greater or less than the amount
of the initial commission (including carrying cost) paid by the Distributor with
respect to such share. In such circumstances, a shareholder of a share may be
deemed to incur expenses attributable to other shareholders of such class. As of
September 30, 2001, there were $1,132,586 and $25,584 of unreimbursed
distribution-related expenses with respect to Class B Shares and Class C Shares,
respectively, representing 3.4% and 0.6% of the Fund's net assets attributable
to Class B

                                       B-34


Shares and Class C Shares, respectively. If the Plans are 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 shares to defray distribution-related expenses
attributable to any other class of shares.

  For the fiscal year ended September 30, 2001, the Fund's aggregate expenses
paid under the Plans for Class A Shares were $86,365 or 0.25% of the Class A
Shares' average daily net assets. Such expenses were paid to reimburse the
Distributor for payments made to financial intermediaries for servicing Class A
shareholders and for administering the Class A Share Plans. For the fiscal year
ended September 30, 2001, the Fund's aggregate expenses paid under the Plans for
Class B Shares were $331,183 or 1.00% of the Class B Shares' average daily net
assets. Such expenses were paid to reimburse the Distributor for the following
payments: $249,006 for commissions and transaction fees paid to financial
intermediaries in respect of sales of Class B Shares of the Fund and $82,177 for
fees paid to financial intermediaries for servicing Class B shareholders and
administering the Class B Share Plans. For the fiscal year ended September 30,
2001, the Fund's aggregate expenses paid under the Plans for Class C Shares were
$28,073 or 1.00% of the Class C Shares' average daily net assets. Such expenses
were paid to reimburse the Distributor for the following payments: $13,128 for
commissions and transaction fees paid to financial intermediaries in respect of
sales of Class C Shares of the Fund and $14,945 for fees paid to financial
intermediaries for servicing Class C shareholders and administering the Class C
Share Plans.

  From time to time, the Distributor may enter into agreements with
broker-dealers to offer the Fund through retirement plan alliance programs that
offer multiple fund families. These programs may have special investment
minimums and operational requirements. For more information, trustees and other
fiduciaries should contact the Distributor.

                                 TRANSFER AGENT

  The Fund's transfer agent, shareholder service agent and dividend disbursing
agent is Van Kampen Investor Services Inc. The transfer agency prices are
determined through negotiations with the Fund's Board of Trustees and are based
on competitive benchmarks.

                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 on such transactions. While
the Adviser will be primarily responsible for the placement of the Fund's
portfolio business, the policies and practices in this regard will at all times
be subject to review by the Board of Trustees of the Fund.

  As most transactions made by the Fund are principal transactions at net
prices, the Fund generally incurs little or no brokerage costs. The portfolio
securities in which the Fund invests are normally purchased directly from the
issuer or in the over-the-counter market 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 a spread or markup to the dealer
between the bid and asked price. Sales to dealers are effected at bid prices.
The Fund may also purchase certain money market instruments directly from an
issuer, in which case no commissions or discounts are paid, or may purchase and
sell listed securities on an exchange, which are effected through brokers who
charge a commission for their services.

                                       B-35


  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 prices and any brokerage commissions on such
transactions, the Adviser considers the firm's reliability, integrity and
financial condition and the firm's execution capability, the size and breadth of
the market for the security, the size of and difficulty in executing the order,
and the best net price. There are many instances when, in the judgment of the
Adviser, more than one firm can offer comparable execution services. In
selecting among such firms, consideration may be given to those firms which
supply research and other services in addition to execution services. The
Adviser is authorized to pay higher commissions to brokerage firms that provide
it with investment and research information than to firms which do not provide
such services if the Adviser determines that such commissions are reasonable in
relation to the overall services provided. No specific value can be assigned to
such research services which are furnished without cost to 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 reduce its
expenses materially. 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 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.

  The Adviser also may place portfolio transactions, to the extent permitted by
law, with brokerage firms affiliated with the Fund, the Adviser or the
Distributor and with brokerage firms participating in the distribution of the
Fund's shares if it reasonably believes that the quality of execution and the
commission are comparable to that available from other qualified firms.
Similarly, to the extent permitted by law and subject to the same considerations
on quality of execution and comparable commission rates, the Adviser may direct
an executing broker to pay a portion or all of any commissions, concessions or
discounts to a firm supplying research or other services.

  The Adviser may place portfolio transactions at or about the same time 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 for 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 sizes of the Fund and other advisory accounts, 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.

  Effective October 31, 1996, Morgan Stanley & Co. Incorporated ("Morgan Stanley
& Co.") became an affiliate of the Adviser. Effective May 31, 1997, Dean Witter
Reynolds, Inc. ("Dean Witter") became an affiliate of the Adviser. The Fund's
Board of Trustees has adopted certain policies incorporating the standards of
Rule 17e-1 issued by the SEC under the 1940 Act which require that the
commissions paid to 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.

                                       B-36


  The Fund paid the following commissions to all brokers and affiliated brokers
during the fiscal years shown:

provided to the Adviser.

                              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. The following information supplements the section
in the Fund's Prospectus captioned "Shareholder Services."

INVESTMENT ACCOUNT

  Each shareholder has an investment account under which the investor's shares
of the Fund are held by Investor Services, the Fund's transfer agent. Investor
Services performs bookkeeping, data processing and administrative services
related to the maintenance of shareholder accounts. Except as described in the
Prospectus and this Statement of Additional Information, after each share
transaction in an account, the shareholder receives a statement showing the
activity in the account. Each shareholder who has an account in any of the Van
Kampen funds will receive statements quarterly from Investor Services showing
any reinvestments of dividends and capital gain dividends 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 gain dividends and systematic purchases or
redemptions. Additional shares may be purchased at any time through authorized
dealers or by mailing a check and detailed instructions directly to Investor
Services.

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 an exchange or
redemption of the shares represented by the certificate. In addition, if such
certificates are lost the shareholder must write to Van Kampen Funds Inc., c/o
Investor Services, PO Box 218256, Kansas City, MO 64121-8256, requesting an
"Affidavit of Loss" and obtain a Surety Bond in a form acceptable to Investor
Services. On the date the letter is received, Investor Services will calculate
the fee for replacing the lost certificate equal to no more than 1.50% of the
net asset value of the issued shares, and bill the party to whom the replacement
certificate was mailed.

RETIREMENT PLANS

  Eligible investors may establish individual retirement accounts ("IRAs"); SEP;
401(k) plans; 403(b)(7) plans in the case of employees of public school systems
and certain non-profit organizations; or other pension or profit sharing plans.
Documents and forms containing detailed information regarding these plans are
available from the Distributor. Van Kampen Trust Company serves as custodian
under the IRA, 403(b)(7) and Money Purchase and Profit Sharing Keogh plans.

                                       B-37


AUTOMATED CLEARING HOUSE ("ACH") DEPOSITS

  Shareholders can use ACH to have redemption proceeds deposited electronically
into their bank accounts. Redemption proceeds 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. To utilize this option, the shareholder's bank
must be a member of ACH. In addition, the shareholder must fill out the
appropriate section of the account application form. The shareholder must also
include a voided check or deposit slip from the bank account into which
redemption proceeds are to be deposited together with the completed application.
Once Investor Services 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 Investor Services or by calling (800) 341-2911 ((800) 421-2833 for the
hearing impaired).

DIVIDEND DIVERSIFICATION

  A shareholder may elect, by completing the appropriate section of the account
application form or by calling (800) 341-2911 ((800) 421-2833 for the hearing
impaired), to have all dividends and capital gain dividends paid on a class of
shares of the Fund invested into shares of the same class of any of the
Participating Funds (as defined in the Prospectus) so long as the investor has a
pre-existing account for such class of shares of the other fund. Both accounts
must be of the same type, either non-retirement or retirement. If the accounts
are retirement accounts, they must both be for the same class and of the same
type of retirement plan (e.g. IRA, 403(b)(7), 401(k), Money Purchase and Profit
Sharing Keogh plans) and for the benefit of the same individual. If a qualified,
pre-existing account does not exist, the shareholder must establish a new
account subject to any requirements of the Participating Fund into which
distributions will be invested. Distributions are invested into the selected
Participating Fund, provided that shares of such Participating Fund are
available for sale, at its net asset value per share as of the payable date of
the distribution from the Fund.

SYSTEMATIC WITHDRAWAL PLAN

  A shareholder may establish a monthly, quarterly, semiannual or annual
withdrawal plan if the shareholder owns shares in a single account valued at
$10,000 or more at the next determined net asset value per share at the time the
plan is established. If a shareholder owns shares in a single account valued at
$5,000 or more at the next determined net asset value per share at the time the
plan is established, the shareholder may establish a quarterly, semiannual 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 payment
represents the proceeds of a redemption of shares on which any capital gain or
loss will be recognized. The planholder may arrange for periodic checks in any
amount not less than $25. Such a systematic withdrawal plan may also be
maintained by an investor purchasing shares for a retirement plan and can be
established on a form made available by the Fund when Van Kampen Trust Company
serves as the plan custodian. See "Shareholder Services -- Retirement Plans."

  Class B Shareholders and Class C Shareholders who establish a systematic
withdrawal plan may redeem up to 12% annually of the shareholder's initial
account balance without incurring a contingent deferred sales charge. Initial
account balance means the amount of the shareholder's investment at the time the
election to participate in the plan is made.

  Under the plan, sufficient shares of the Fund are redeemed to provide the
amount of the periodic withdrawal payment. Dividends and capital gain dividends
on shares held in accounts with systematic withdrawal plans are reinvested in
additional shares at the next determined net asset value per share. If periodic
withdrawals continuously exceed reinvested dividends and capital gain dividends,
the shareholder's original investment will be correspondingly reduced and
ultimately exhausted. Redemptions made concurrently with the purchase of
additional shares ordinarily will be disadvantageous to the shareholder because
of the duplication of sales charges. Any gain or loss realized by the
shareholder upon redemption of shares is a taxable event. The Fund reserves the
right to amend or terminate the systematic withdrawal program upon 30 days'
notice to its shareholders.

                                       B-38


REINSTATEMENT PRIVILEGE

  A Class A Shareholder or Class B Shareholder who has redeemed shares of the
Fund may reinstate any portion or all of the net proceeds of such redemption
(and may include that amount necessary to acquire a fractional share to round
off his or her purchase to the next full share) in Class A Shares of the Fund. A
Class C Shareholder who has redeemed shares of the Fund may reinstate any
portion or all of the net proceeds of such redemption (and may include that
amount necessary to acquire a fractional share to round off his or her purchase
to the next full share) in Class C Shares of the Fund with credit given for any
contingent deferred sales charge paid upon such redemption, provided that such
shareholder has not previously exercised this reinstatement 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 (defined below) to subsequent
redemptions. Such reinstatement is made at the net asset value per share
(without sales charge) next determined after the order is received, which must
be made within 180 days after the date of the redemption, provided that shares
of the Fund are available for sale. Reinstatement at net asset value per share
is also offered to participants in those eligible retirement plans held or
administered by Van Kampen Trust Company for repayment of principal (and
interest) on their borrowings on such plans, provided that shares of the Fund
are available for sale.

                              REDEMPTION OF SHARES

  Redemptions are not made on days during which the New York Stock Exchange (the
"Exchange") is closed. 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) the
SEC determines trading on the Exchange is restricted; (c) the SEC determines an
emergency exists as a result of which disposal by the Fund of securities owned
by it is not reasonably practicable or it is not reasonably practicable for the
Fund to fairly determine the value of its net assets; or (d) the SEC, by order,
so permits.

  In addition, if the Fund's Board of Trustees determines that payment wholly or
partly in cash would be detrimental to the best interests of the remaining
shareholders of the Fund, the Fund may pay the redemption proceeds in whole or
in part by a distribution-in-kind of portfolio securities held by the Fund in
lieu of cash in conformity with applicable rules of the SEC. A
distribution-in-kind may result in recognition by the shareholder of a gain or
loss for federal income tax purposes when such securities are distributed, and
the shareholder may have brokerage costs and a gain or loss for federal income
tax purpose upon the shareholder's disposition of such securities.

                    CONTINGENT DEFERRED SALES CHARGE-CLASS A

  As described in the Fund's Prospectus under "Purchase of Shares -- Class A
Shares," there is no sales charge payable on Class A Shares at the time of
purchase on investments of $1 million or more, but a contingent deferred sales
charge ("CDSC -- Class A") may be imposed on certain redemptions made within one
year of purchase. For purposes of the CDSC-Class A, when shares of a
Participating Fund are exchanged for shares of another Participating 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 being redeemed first are any shares in the shareholder's account not
subject to a contingent deferred sales charge followed by shares held the
longest in the shareholder's account. The contingent deferred sales charge is
assessed on an amount equal to the lesser of the then current market value or
the cost of the shares being redeemed. Accordingly, no sales charge is imposed
on increases in net asset value above the initial purchase price. In addition,
no sales charge is assessed on shares derived from reinvestment of dividends or
capital gain dividends.

                                       B-39


        WAIVER OF CLASS B AND CLASS C CONTINGENT DEFERRED SALES CHARGES

  As described in the Fund's Prospectus under "Redemption of Shares,"
redemptions of Class B Shares and Class C Shares will be subject to a contingent
deferred sales charge ("CDSC-Class B and C"). The CDSC-Class B and C is waived
on redemptions of Class B Shares and Class C Shares in the circumstances
described below:

REDEMPTION UPON DEATH OR DISABILITY

  The Fund will waive the CDSC-Class B and C on redemptions following the death
or disability of a Class B shareholder 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 of 1986, as amended
(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 death or disability, 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 partial redemption, but only to
redemptions of shares held at the time of the death or initial determination of
disability.

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
CDSC--Class B and C will be waived upon the tax-free rollover or transfer of
assets to another retirement plan invested in one or more Participating 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 or other contribution pursuant
to Code Section 408(d)(4) or (5), the return of excess contributions or excess
deferral amounts pursuant to Code Section 401(k)(8) or 402(g)(2), the financial
hardship of the employee pursuant to U. S. Treasury regulation Section
1.401(k)-1(d)(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.

REDEMPTION PURSUANT TO THE FUND'S SYSTEMATIC WITHDRAWAL PLAN

  A shareholder may elect to participate in a systematic withdrawal plan with
respect to the shareholder's investment in the Fund. Under the systematic
withdrawal 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 sent to the designated payee of record. 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 systematic withdrawal plan. The
CDSC-Class B and C will be waived on redemptions made under the systematic
withdrawal plan.

                                       B-40


  The amount of the shareholder's investment in the Fund at the time the
election to participate in the systematic withdrawal plan is made with respect
to the Fund is hereinafter referred to as the "initial account balance." The
amount to be systematically redeemed from the 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 systematic withdrawal plan and the ability to offer the
systematic withdrawal plan.

NO INITIAL COMMISSION OR TRANSACTION FEE

  The Fund will waive the CDSC-Class B and C in circumstances under which no
commission or transaction fee is paid to authorized dealers at the time of
purchase of shares. See "Purchase of Shares -- Waiver of Contingent Deferred
Sales Charge" in the Prospectus.

INVOLUNTARY REDEMPTIONS OF SHARES

  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 value of the
account up to the required minimum balance. The Fund will waive the CDSC-Class B
and C upon such involuntary redemption.

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.

                                    TAXATION

FEDERAL INCOME TAXATION OF THE FUND

  The Trust and each of its series, including the Fund, will be treated as
separate corporations for federal income tax purposes. The Fund has elected and
qualified, and intends to continue to qualify each year, to be treated as a
regulated investment company under Subchapter M of the Code. To qualify as a
regulated investment company, the Fund must comply with certain requirements of
the Code relating to, among other things, the sources of its income and
diversification of its assets.

  If the Fund so qualifies and distributes each year to its shareholders at
least an amount equal to the sum of (i) 90% of its investment company taxable
income (generally including ordinary income and net short-term capital gain, but
not net capital gain, which is the excess of net long-term capital gain over net
short-term capital loss) and (ii) 90% of its net tax-exempt interest income, and
meets certain other requirements, it will not be required to pay federal income
taxes on any income it distributes to shareholders. The Fund intends to
distribute at least the minimum amount necessary to satisfy the 90% distribution
requirement. The Fund will not be subject to federal income tax on any net
capital gain distributed to shareholders.

  To avoid a 4% excise tax, the Fund will be required to distribute, by December
31st of each year, at least an amount equal to the sum of (i) 98% of its
ordinary income (not including tax-exempt income) for such year and (ii) 98% of
its capital gain net income (the latter of which generally is computed on the
basis of the one-year period ending on October 31st of such year) plus any
amounts that were not distributed in previous taxable years. For purposes of the
excise tax, any ordinary income or capital gain net income retained by, and
subject to federal income tax in the hands of, the Fund will be treated as
having been distributed.

  If the Fund failed to qualify as a regulated investment company or failed to
satisfy the 90% distribution requirement in any taxable year, the Fund would be
taxed as an ordinary corporation on its taxable income (even if such income were
distributed to its shareholders) and all distributions out of earnings and
profits would be taxed to shareholders as ordinary income. In addition, the Fund
could be required to recognize unrealized gains, pay taxes and make
distributions (which could be subject to interest charges) before requalifying
as a regulated investment company.

                                       B-41


  Some of the Fund's investment practices are subject to special provisions of
the Code that may, among other things, (i) disallow, suspend or otherwise limit
the allowance of certain losses or deductions, (ii) convert lower taxed
long-term capital gain into higher taxed short-term capital gain or ordinary
income, (iii) convert an ordinary loss or a deduction into a capital loss (the
deductibility of which is more limited) and/or (iv) cause the Fund to recognize
income or gain without a corresponding receipt of cash with which to make
distributions in amounts necessary to satisfy the 90% distribution requirement
and the distribution requirements for avoiding income and excise taxes. The Fund
will monitor its transactions and may make certain tax elections 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 to maintain its qualification as a
regulated investment company and to avoid income and excise taxes. To generate
sufficient cash to make distributions necessary to satisfy the 90% distribution
requirement and to avoid income and excise taxes, the Fund may have to dispose
of securities that it would otherwise have continued to hold.

DISTRIBUTIONS TO SHAREHOLDERS

  The Fund intends to invest in sufficient tax-exempt municipal securities to
permit payment of "exempt-interest dividends" (as defined in the Code).
Dividends paid by the Fund from the net tax-exempt interest earned from
municipal securities qualify as exempt-interest dividends if, at the close of
each quarter of its taxable year, at least 50% of the value of the total assets
of the Fund consists of such securities.

  Certain limitations on the use and investment of the proceeds of state and
local government bonds and other funds must be satisfied to maintain the
exclusion from gross income for interest on such bonds. These limitations
generally apply to bonds issued after August 15, 1986. In light of these
requirements, bond counsel qualify their opinions as to the federal tax status
of bonds issued after August 15, 1986 by making them contingent on the issuer's
future compliance with these limitations. Any failure on the part of an issuer
to comply could cause the interest on its bonds to become taxable to investors
retroactive to the date the bonds were issued.

  Except as provided below, exempt-interest dividends paid to shareholders
generally are not includable in the shareholders' gross income for federal
income tax purposes. The percentage of the total dividends paid by the Fund
during any taxable year that qualify as exempt-interest dividends will be the
same for all shareholders of the Fund receiving dividends during such year.

  Interest on certain "private-activity bonds" is an item of tax preference
subject to the federal alternative minimum tax on individuals and corporations.
The Fund invests a portion of its assets in municipal securities subject to this
provision so that a portion of its exempt-interest dividends is an item of tax
preference to the extent such dividends represent interest received from these
private-activity bonds. Accordingly, investment in the Fund could cause
shareholders to be subject to (or result in an increased liability under) the
alternative minimum tax. Per capita volume limitations on certain
private-activity bonds could limit the amount of such bonds available for
investment by the Fund.

  Exempt-interest dividends are included in determining what portion, if any, of
a person's social security and railroad retirement benefits will be includable
in gross income subject to federal income tax.

  Although exempt-interest dividends generally may be treated by Fund
shareholders as items of interest excluded from their gross income for federal
income tax purposes, 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" of a
substantial user) of the facilities financed 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

                                       B-42


exceed 5% of the total revenues derived from the facilities by all users, or who
occupies more than 5% of the useable area of the facilities or for whom the
facilities or a part thereof were specifically constructed, reconstructed or
acquired. Examples of "related persons" include certain related natural persons,
affiliated corporations, a partnership and its partners and an S corporation and
its shareholders.

  While the Fund expects that a major portion of its net investment income will
constitute tax-exempt interest, a significant portion may consist of investment
company taxable income. Distributions of the Fund's investment company taxable
income are taxable to shareholders as ordinary income to the extent of the
Fund's earnings and profits, whether paid in cash or reinvested in additional
shares. Distributions of the Fund's net capital gain as capital gain dividends,
if any, are taxable to shareholders as long-term capital gain regardless of the
length of time shares of the Fund have been held by such shareholders.
Distributions in excess of the Fund's earnings and profits will first reduce the
adjusted tax basis of a shareholder's shares and, after such adjusted tax basis
is reduced to zero, will constitute capital gain to such shareholder (assuming
such shares are held as a capital asset). For a summary of the maximum tax rates
applicable to capital gain (including capital gain dividends), see "Capital
Gains Rates" below. Some or all of the interest on indebtedness incurred to
purchase or carry shares of a mutual fund which distributes exempt-interest
dividends during the year will not be deductible for federal income tax
purposes, depending upon the ratio of the exempt-interest dividends to the total
of exempt-interest dividends plus taxable dividends received by the shareholder
(excluding capital gain dividends) during the year.

  Shareholders receiving distributions in the form of additional shares issued
by the Fund will be treated for federal income tax purposes as receiving a
distribution in an amount equal to the fair market value of the shares received,
determined as of the distribution date. The basis of such shares will equal
their fair market value on the distribution date.

  The Fund will inform shareholders of the source and tax status of all
distributions promptly after the close of each calendar year. The aggregate
amount of dividends designated as exempt-interest dividends cannot exceed the
excess of 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 taxable 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.
Distributions from the Fund generally will not be eligible for the corporate
dividends received deduction.

  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in such month and paid during January of the
following year will be treated as having been distributed by the Fund and
received by the shareholders on the December 31st prior to the date of payment.
In addition, certain other distributions made after the close of a taxable year
of the Fund may be "spilled back" and treated as paid by the Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
shareholders will be treated as having received such dividends in the taxable
year in which the distribution was actually made.

SALE OF SHARES

  The sale of shares (including transfers in connection with a redemption or
repurchase of shares) may be a taxable transaction for federal income tax
purposes. Selling shareholders will generally recognize a gain or loss in an
amount equal to the difference between their adjusted tax basis in the shares
sold and the amount received. If the shares sold are held as a capital asset,
the gain or loss will be a capital gain or loss. For a summary of the maximum
tax rates applicable to capital gains, see "Capital Gains Rates" below. Any loss
recognized upon a taxable disposition of shares held for six months or less will
be disallowed to the extent of any exempt-interest dividends received with
respect to such shares and will be treated as a long-term capital loss to the
extent of any capital gain dividends received with respect to such shares. For
purposes of determining whether shares have been held for six months or less,
the holding period is suspended for any

                                       B-43


periods during which the shareholder's risk of loss is diminished as a result of
holding one or more other positions in substantially similar or related property
or through certain options or short sales.

CAPITAL GAINS RATES

  The maximum tax rate applicable to net capital gains recognized by individuals
and other non-corporate taxpayers investing in the Fund is (i) the same as the
maximum ordinary income tax rate for capital assets held for one year or less or
(ii) 20% for capital assets held for more than one year. The maximum long-term
capital gains rate for corporations is 35%.

BACKUP WITHHOLDING

  The Fund may be required to withhold federal income tax ("backup withholding")
from dividends and redemption proceeds paid to non-corporate shareholders. This
tax may be withheld from dividends if (i) the shareholder fails to properly
furnish the Fund with its correct taxpayer identification number, (ii) the IRS
notifies the Fund that the shareholder has failed to properly report certain
interest and dividend income to the IRS and to respond to notices to that effect
or (iii) when required to do so, the shareholder fails to certify that he or she
is not subject to backup withholding. Redemption proceeds may be subject to
backup withholding under the circumstances described in (i) above.

  Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules from payments made to a shareholder may be refunded or
credited against such shareholder's U.S. federal income tax liability, if any,
provided that the required information is furnished to the IRS.

INFORMATION REPORTING

  The Fund must report annually to the IRS and to each shareholder the amount of
dividends, capital gain dividends or gross proceeds paid to such shareholder and
the amount, if any, of tax withheld pursuant to backup withholding rules with
respect to such amounts.

GENERAL

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

  The table below illustrates approximate equivalent taxable and tax-free yields
at the federal individual income tax rates in effect on the date of this
Statement of Additional Information.

  The table shows, for example, that a couple with a taxable income of $90,000,
or a single individual with a taxable income of $55,000, whose investments earn
a 6% tax-free yield, would have to earn approximately an 8.33% taxable yield at
current federal income tax rates to receive the same benefit.

  The State of Florida imposes no income tax on individuals; accordingly, the
table reflects only the exemption from Federal income taxes. The table does not
reflect the exemption of shares of the Fund from the State's intangible tax;
accordingly, Florida residents subject to such tax would need a somewhat higher
taxable return than those shown to equal the tax-exempt return of the Florida
Fund.

                                FUND PERFORMANCE

  From time to time the Fund may advertise its total return for prior periods.
Any such advertisement would include at least average annual total return
quotations for one year, five year and ten year periods. Other total return
quotations, aggregate or average, over other time periods may also be included.

  The total return of the Fund for a particular period represents the increase
(or decrease) in the value of a hypothetical investment in the Fund from the
beginning to the end of the period. Total return is calculated by subtracting
the value of the initial investment from the ending value and showing the
difference as a percentage of the initial investment; the calculation assumes
the initial investment is made at the current maximum public offering price
(which includes the maximum sales charge for Class A Shares); that all income
dividends or capital gain dividends during the period are reinvested in Fund
shares at net asset value; and that any applicable contingent deferred sales
charge has been paid. The Fund's total return will vary depending on market
conditions, the securities comprising the Fund's portfolio, the Fund's operating
expenses and unrealized net capital gains or losses during the period. Total
return is based on historical earnings and asset value fluctuations and is not
intended to indicate future performance. No adjustments are made to reflect any
income taxes payable by shareholders on dividends or capital gain dividends paid
by the Fund.

  Average annual total return quotations are computed by finding the average
annual compounded rate of return over the period that would equate the initial
amount invested to the ending redeemable value.

  The Fund may, in supplemental sales literature, advertise non-standardized
total return figures representing the cumulative, non-annualized total return of
each class of shares of the Fund from a given date to a subsequent given date.
Cumulative non-standardized total return is calculated by measuring the value of
an initial investment in a given class of shares of the Fund at a given time,
deducting the maximum initial sales charge, if any, determining the value of all
subsequent reinvested distributions, and dividing the net change in the value of
the investment as of the end of the period by the amount of the initial
investment and expressing the result as a percentage. Non-standardized total
return will be calculated separately for each class of shares.

  Non-standardized total return calculations do not reflect the imposition of a
contingent deferred sales charge, and if any contingent deferred sales charge
imposed at the time of redemption were reflected, it would reduce the
performance quoted.

  In addition to total return information, the Fund may also advertise its
current "yield." Yield figures are based on historical earnings and are not
intended to indicate future performance. Yield is determined by analyzing the
Fund's net income per share for a 30-day (or one-month) period (which period
will be stated in the advertisement), and dividing by the maximum offering price
per share on the last day of the period. A "bond equivalent" annualization
method is used to reflect a semiannual compounding.

  For purposes of calculating yield quotations, net income is determined by a
standard formula prescribed by the SEC to facilitate comparison with yields
quoted by other investment companies. Net income computed for this formula
differs from net income reported by the Fund in accordance with generally
accepted accounting principles and from net income computed for federal income
tax reporting purposes. Thus the yield computed for a period may be greater or
less than the Fund's then current dividend rate.

  The Fund's yield is not fixed and will fluctuate in response to prevailing
interest rates and the market value of portfolio securities, and as a function
of the type of securities owned by the Fund, portfolio maturity and the Fund's
expenses.

  Yield quotations should be considered relative to changes in the net asset
value of the Fund's shares, the Fund's investment policies, and the risks of
investing in shares of the Fund. The investment return and principal value of an
investment in the Fund will fluctuate so that an investor's shares, when
redeemed, may be worth more or less than their original cost.

  Yield and total return are calculated separately for Class A Shares, Class B
Shares and Class C Shares of the Fund. Total return figures for Class A Shares
include the maximum sales charge. Total return figures for Class B Shares and
Class C Shares include any applicable contingent deferred sales charge. Because
of the differences in sales charges and distribution fees, the total returns for
each class of shares will differ.

                                       B-45


  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 differs from yield, which is a measure of
the income actually earned by the Fund's investments, and from total return
which is a measure of the income actually earned by the Fund's investments plus
the effect of any realized and unrealized appreciation or depreciation of such
investments during a stated period. Distribution rate is, therefore, not
intended to be a complete measure of the Fund's performance. Distribution rate
may sometimes be greater than yield since, for instance, it may not include the
effect of amortization of bond premiums, and may include non-recurring
short-term capital gains and premiums from futures transactions engaged in by
the Fund. Distribution rates will be computed separately for each class of the
Fund's shares.

  From time to time marketing materials may provide a portfolio manager update,
an Adviser update and discuss general economic conditions and outlooks. The
Fund's marketing materials may also show the Fund's asset class diversification,
top sector holdings and largest holdings and other Fund information, such as
duration, maturity, coupon, NAV, rating breakdown, AMT exposure and number of
issues in the portfolio. Materials may also mention how the Distributor believes
the Fund compares relative to other Van Kampen funds. Materials may also discuss
the Dalbar Financial Services study from 1984 to 1994 which studied investor
cash flow into and out of all types of mutual funds. The ten-year study found
that investors who bought mutual fund shares and held such shares outperformed
investors who bought and sold. The Dalbar study conclusions were consistent
regardless of whether shareholders purchased their fund shares in direct or
sales force distribution channels. The study showed that investors working with
a professional representative have tended over time to earn higher returns than
those who invested directly. The performance of the funds purchased by the
investors in the Dalbar study and the conclusions based thereon are not
necessarily indicative of future performance of such funds or conclusions that
may result from similar studies in the future. The Fund may also be marketed on
the internet.

  In reports or other communications to shareholders or in advertising material,
the Fund may compare its performance with that of other mutual funds as listed
in the rankings or ratings prepared by Lipper Analytical Services, Inc., CDA,
Morningstar Mutual Funds or similar independent services which monitor the
performance of mutual funds with the Consumer Price Index, other appropriate
indices of investment securities, or with investment or savings vehicles. The
performance information may also include evaluations of the Fund published by
nationally recognized ranking or rating services and by nationally recognized
financial publications. Such comparative performance information will be stated
in the same terms in which the comparative data or indices are stated. Such
advertisements and sales material may also include a yield quotation as of a
current period. In each case, such total return and yield information, if any,
will be calculated pursuant to rules established by the SEC and will be computed
separately for each class of the Fund's shares. For these purposes, the
performance of the Fund, as well as the performance of other mutual funds or
indices, do not reflect sales charges, the inclusion of which would reduce the
Fund's performance. The Fund will include performance data for each class of
shares of the Fund in any advertisement or information including performance
data of the Fund.

  The Fund may also utilize performance information in hypothetical
illustrations. For example, 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.

  Tax-equivalent yield demonstrates the taxable yield required to produce an
after-tax yield equivalent to that of the Fund's yield. The Fund's
tax-equivalent yield quotation for a 30 day period as described above is
computed by dividing that portion of the yield of the Fund (as computed above)
which is tax-exempt by a percentage equal to 100% minus a stated percentage
income tax rate and adding the result to that portion of the Fund's yield, if
any, that is not tax-exempt.

                                       B-46


  The Fund's Annual Report and Semiannual Report contain additional performance
information. A copy of the Annual Report or Semiannual Report may be obtained
without charge by calling or writing the Fund at the telephone number and
address printed on the cover of this Statement of Additional Information.

CLASS A SHARES

  The Fund's average annual total return, assuming payment of the maximum sales
charge, for Class A Shares of the Fund for (i) the one-year period ended
September 30, 2001 was 5.63%, (ii) the five-year period ended September 30, 2001
was 5.02% and (iii) the approximately seven-year, two-month period from July 29,
1994 (commencement of distribution of Class A Shares of the Fund) through
September 30, 2001 was 5.69%.

  The Fund's yield with respect to the Class A Shares for the 30-day period
ending September 30, 2001 was 3.82%. The Fund's current distribution rate with
respect to the Class A Shares for the month ending September 30, 2001 was 4.41%.
The Fund's taxable equivalent distribution rate with respect to the Class A
Shares for the month ending September 30, 2001 was 7.24%.

  The Fund's cumulative non-standardized total return, including payment of the
maximum sales charge, with respect to the Class A Shares from its inception to
September 30, 2001 was 48.75%.

  The Fund's cumulative non-standardized total return, excluding payment of the
maximum sales charge, with respect to the Class A Shares from its inception to
September 30, 2001 was 56.14%.

CLASS B SHARES

  The Fund's average annual total return for Class B Shares listed below
reflects the conversion of such shares into Class A Shares. Class B Shares
purchased before June 1, 1996, including Class B Shares received from
reinvestment of distributions through the dividend reinvestment plan,
automatically convert to Class A Shares seven years after the end of the
calendar month in which the shares were purchased. Class B Shares purchased on
or after June 1, 1996 will convert to Class A Shares eight years after the end
of the calendar month in which the shares were purchased.

  The Fund's average annual total return, assuming payment of the contingent
deferred sales charge, for Class B Shares of the Fund for (i) the one-year
period ended September 30, 2001 was 6.12%, (ii) the five-year period ended
September 30, 2001 was 5.02% and (iii) the approximately seven-year, two-month
period from July 29, 1994 (commencement of distribution of Class B Shares of the
Fund) through September 30, 2001 was 5.65%.

  The Fund's yield with respect to the Class B Shares for the 30-day period
ending September 30, 2001 was 3.25%. The Fund's current distribution rate with
respect to the Class B Shares for the month ending September 30, 2001 was 3.90%.
The Fund's taxable equivalent distribution rate with respect to the Class B
Shares for the month ending September 30, 2001 was 6.40%.

  The Fund's cumulative non-standardized total return, including payment of the
contingent deferred sales charge, with respect to the Class B Shares from July
29, 1994 (commencement of distribution of Class B Shares of the Fund) to
September 30, 2001 was 48.31%.

  The Fund's cumulative non-standardized total return, excluding payment of the
contingent deferred sales charge, with respect to the Class B Shares from July
29, 1994 (commencement of distribution of Class B Shares of the Fund) to
September 30, 2001 was 48.31%.

                       DESCRIPTION OF SECURITIES RATINGS

  STANDARD & POOR'S -- A brief description of the applicable Standard & Poor's
(S&P) rating symbols and their meanings (as published by S&P follows):

  A S&P issue credit rating is a current opinion of the creditworthiness of an
obligor with respect to a specific financial obligation, a specific class of
financial obligations, or a specific financial program (including ratings on
medium term note programs and commercial paper programs). It takes into
consideration the creditworthiness of guarantors, insurers, or other forms of
credit enhancement on the obligation and takes into account the currency in
which the obligation is denominated.

  The issue credit rating is not a recommendation to purchase, sell, or hold a
financial obligation, inasmuch as it does not comment as to market price or
suitability for a particular investor.

                                       B-48


  Issue credit ratings are based on current information furnished by the
obligors or obtained by S&P from other sources it considers reliable. S&P does
not perform an audit in connection with any credit rating and may, on occasion,
rely on unaudited financial information. Credit ratings may be changed,
suspended, or withdrawn as a result of changes in, or unavailability of, such
information, or based on other circumstances.

  Issue credit ratings can be either long-term or short-term. Short-term ratings
are generally assigned to those obligations considered short-term in the
relevant market. In the U.S., for example, that means obligations with an
original maturity of no more than 365 days including commercial paper.
Short-term ratings are also used to indicate the creditworthiness of an obligor
with respect to put features on long-term obligations. The result is a dual
rating, in which the short-term rating addresses the put feature, in addition to
the usual long-term rating. Medium-term notes are assigned long-term ratings.

LONG-TERM ISSUE CREDIT RATINGS

  Issue credit ratings are based, in varying degrees, on the following
considerations:

  1. Likelihood of payment--capacity and willingness of the obligor to meet its
     financial commitment on an obligation 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.

  The issue rating definitions are expressed in terms of default risk. As such,
they pertain to senior obligations of an entity. Junior obligations are
typically rated lower than senior obligations, to reflect the lower priority in
bankruptcy, as noted above. (Such differentiation applies when an entity has
both senior and subordinated obligations, secured and unsecured obligations, or
operating company and holding company obligations.) Accordingly, in the case of
junior debt, the rating may not conform exactly with the category definition.

  AAA: An obligation rated "AAA" has the highest rating assigned by S&P. The
obligor's capacity to meet its financial commitment on the obligation is
extremely strong.

  AA: An obligation rated "AA" differs from the highest rated obligations only
in small degree. The obligor's capacity to meet its financial commitment on the
obligation is very strong.

  A: An obligation rated "A" is somewhat more susceptible to the adverse effects
of changes in circumstances and economic conditions than obligations in higher
rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

  BBB: An obligation rated "BBB" exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

SPECULATIVE GRADE

  BB, B, CCC, CC, C: Obligations rated "BB", "B", "CCC", "CC" and "C" are
regarded as having significant speculative characteristics. "BB" indicates the
least degree of speculation and "C" the highest.

  While such obligations will likely have some quality and protective
characteristics, these may be outweighed by large uncertainties or major
exposures to adverse conditions.

  BB: An obligation rated "BB" is less vulnerable to nonpayment than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial, or economic conditions which could lead to the
obligor's inadequate capacity to meet its financial commitment on the
obligation.

  B: An obligation rated "B" is more vulnerable to nonpayment than obligations
rated "BB", but the obligor currently has the capacity to meet its financial
commitment on the obligation. Adverse business, financial, or economic
conditions will likely impair the obligor's capacity or willingness to meet its
financial commitment on the obligation.
                                       B-49


  CCC: An obligation rated "CCC" is currently vulnerable to nonpayment, and is
dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation. In the event of
adverse business, financial, or economic conditions, the obligor is not likely
to have the capacity to meet its financial commitment on the obligation.

  CC: An obligation rated "CC" is currently highly vulnerable to nonpayment.

  C: A subordinated debt rated "C" is CURRENTLY HIGHLY VULNERABLE to nonpayment.
The "C" rating may be used to cover a situation where a bankruptcy petition has
been filed or similar action taken, but payments on this obligation are being
continued.

  D: An obligation debt rated "D" is in payment default. The "D" rating category
is used when payments on an obligation 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 or the taking of a similar action if payments on
an obligation are jeopardized. Plus (+) or minus (-): The ratings from 'AA' to
'CCC' may be modified by the addition of a plus or minus sign to show relative
standing within the major rating categories.

  r: This symbol is attached to the ratings of instruments with significant
noncredit risks. It highlights risks to principal or volatility of expected
returns which are not addressed in the credit rating.

  N.R.: This 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 obligation as a matter of policy.

MUNICIPAL NOTES

  A S&P note rating reflects the liquidity factors and market access risks
unique to notes. Notes due in 3 years or less will likely receive a note rating.
Notes maturing beyond 3 years will most likely receive a long-term debt rating.
The following criteria will be used in making that assessment.

  -- Amortization schedule (the larger the final maturity relative to other
     maturities, the more likely it will be treated as a note); and

  -- Source of payment (the more dependent the issue is on the market for its
     refinancing, the more likely it will be treated as a note).

  Note rating symbols are as follows:

  SP-1: Strong capacity to pay principal and interest. An issue determined to
possess a very strong capacity to pay debt service is given 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.

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.

  A-1: A commercial paper obligation rated 'A-1' is rated in the highest
category by Standard & Poor's. The obligor's capacity to meet its financial
commitment on the obligation is strong. Within this category, certain
obligations are designated with a plus sign (+). This indicates that the
obligor's capacity to meet its financial commitment on these obligations is
extremely strong.

  A-2: A commercial paper obligation rated 'A-2' is somewhat more susceptible to
the adverse effects of changes in circumstances and economic conditions than
obligations in higher rating categories. However, the obligor's capacity to meet
its financial commitment on the obligation is satisfactory.

                                       B-50


  A-3: A commercial paper obligation rated 'A-3' exhibits adequate protection
parameters. However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitment on the obligation.

  B: A commercial paper obligation rated 'B' is regarded as having significant
speculative characteristics. The obligor currently has the capacity to meet its
financial commitment on the obligation; however, it faces major ongoing
uncertainties which could lead to the obligor's inadequate capacity to meet its
financial commitment on the obligation.

  C: A commercial paper obligation rated 'C' is currently vulnerable to
nonpayment and is dependent upon favorable business, financial, and economic
conditions for the obligor to meet its financial commitment on the obligation.

  D: A commercial paper obligation rated 'D' is in payment default. The 'D'
rating category is used when payments on an obligation are not made on the date
due even if the applicable grace period has not expired, unless Standard &
Poor's 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 or the
taking of a similar action if payments on an obligation are jeopardized.

  A commercial paper 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 to
S&P by the issuer or obtained 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.

TAX-EXEMPT DUAL RATINGS

  S&P assigns "dual" ratings to all debt issues that have a put option or demand
feature as part of their structure. The first rating addresses the likelihood of
repayment of principal and interest as due, and the second rating addresses only
the demand feature. The long-term debt rating symbols are used for bonds to
denote the long-term maturity and the commercial paper rating symbols for the
put option (for example, 'AAA/A-1+'). With short-term demand debt, S&P's note
rating symbols are used with the commercial paper rating symbols (for example,
'SP-1+/A-1+').

  MOODY'S INVESTORS SERVICE INC. -- A brief description of the applicable
Moody's Investors Service, Inc. (Moody's) rating symbols and their meanings (as
published by Moody's) follows:

  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 risks 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

                                       B-51


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.

  Moody's assigns ratings to individual long-term debt securities issued from
medium-term note (MTN) programs, in addition to indicating ratings to MTN
programs themselves. Notes issued under MTN programs with such indicated ratings
are rated at issuance at the rating applicable to all pari passu notes issued
under the same program, at the program's relevant indicated rating, provided
such notes do not exhibit any of the characteristics listed below. For notes
with any of the following characteristics, the rating of the individual note may
differ from the indicated rating of the program:

  1) Notes containing features which link the cash flow and/or market value to
     the credit performance of any third party or parties.

  2) Notes allowing for negative coupons, or negative principal.

  3) Notes containing any provision which could obligate the investor to make
     any additional payments.

  Market participants must determine whether any particular note is rated, and
if so, at what rating level. Moody's encourages market participants to contact
Moody's Ratings Desks directly if they have questions regarding ratings for
specific notes issued under a medium-term note program.

  Note: Moody's applies numerical modifiers, 1, 2, and 3 in each generic rating
classification from Aa through Caa. The modifier 1 indicates that the obligation
ranks in the higher end of its generic rating category; the modifier 2 indicates
a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of
that generic rating category.

SHORT-TERM EXEMPT NOTES

  In municipal debt issuance, there are three rating categories for short-term
obligations that are considered investment grade. These ratings are designated
as Moody's Investment Grade (MIG) and are divided into three levels--MIG 1
through MIG 3.

  In addition, those short-term obligations that are of speculative quality are
designated SG, or speculative grade.

  In the case of variable rate demand obligations (VRDOs), a two-component
rating is assigned. The first element represents Moody's evaluation of the
degree of risk associated with scheduled principal and interest payments. The
second element represents Moody's evaluation of the degree of risk associated
with the demand feature, using the MIG rating scale.

                                       B-52


  The short-term rating assigned to the demand feature of VRDOs is designated as
VMIG. When either the long- or short-term aspect of a VRDO is not rated, that
piece is designated NR, e.g., Aaa/NR or NR/VMIG 1.

  MIG ratings expire at note maturity. By contrast, VMIG rating expirations will
be a function of each issue's specific structural or credit features.

  MIG 1/VMIG 1. This designation denotes superior credit quality. Excellent
protection is afforded by established cash flows, highly reliable liquidity
support, or demonstrated broad-based access to the market for refinancing.

  MIG 2/VMIG 2. This designation denotes strong credit quality. Margins of
protection are ample, although not so large as in the preceding group.

  MIG 3/VMIG 3. This designation denotes acceptable credit quality. Liquidity
and cash-flow protection may be narrow, and market access for refinancing is
likely to be less well-established.

  SG. This designation denotes speculative-grade credit quality. Debt
instruments in this category may lack sufficient margins of protection.

TAX-EXEMPT COMMERCIAL PAPER

  Moody's short-term issuer ratings are opinions of the ability of issuers to
honor senior financial obligations and contracts. Such obligations generally
have an original maturity not exceeding one year, unless explicitly noted.

  Moody's employs the following 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. Prime-1 repayment ability will
often be evidenced by many of the following characteristics:

  -- Leading market positions in well established industries.

  -- High rates of return on funds employed.

  -- Conservative capitalization structure with moderate reliance on debt and
     ample asset protection.

  -- Broad margins in earnings coverage of fixed financial charges and high
     internal cash generation.

  -- Well established access to a ranges of financial markets and assured
     sources of alternative liquidity.

  Issuers rated Prime-2 (or supporting institutions) have a strong ability to
repay senior short-term debt obligations. This will normally be evidenced by
many of the characteristics cited above but to a lesser degree. Earnings trends
and coverage ratios, while sound, may be more subject to variation than is the
case for Prime-1 Securities. Capitalization characteristics, while still
appropriate, may be more affected by external conditions. Ample alternate
liquidity is maintained.

  Issuers rated Prime-3 (or supported institutions) have an acceptable ability
for repayment of senior short-term obligations. The effect of industry
characteristics and market compositions may be more pronounced. Variability in
earnings and profitability may result in changes in the level of debt-protection
measurements and may require relatively high financial leverage. Adequate
alternate liquidity is maintained.

  Issuers rated Not Prime do not fall within any of the prime rating categories.

  In addition, in certain countries the prime rating may be modified by the
issuer's or guarantors senior unsecured long-term debt rating.

                                       B-53


REPORT OF INDEPENDENT AUDITORS

To the Shareholders and Board of Trustees of Van Kampen Florida Insured Tax Free
Income Fund:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Van Kampen Florida Insured Tax Free Income Fund
(the "Fund"), as of September 30, 2001, and the related statements of operations
for the year then ended, and the statements of changes in net assets and
financial highlights for the two years then ended. 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. The financial highlights of the Fund
for each of the indicated years in the period ended September 30, 1999 were
audited by other auditors whose report dated November 11, 1999 expressed an
unqualified opinion on those financial highlights.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States. 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 September 30, 2001, 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 the
Fund at September 30, 2001, the results of its operations for the year then
ended, and the changes in its net assets and financial highlights for each of
the two years in the period then ended, in conformity with accounting principles
generally accepted in the United States.

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Florida Insured Tax Free Income Fund (the "Fund") is organized as a
series of the Van Kampen Tax Free Trust, a Delaware business trust, and is
registered as a non-diversified open-end management investment company under the
Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's
investment objective is to provide a high level of current income exempt from
federal income tax and Florida intangible personal property taxes, consistent
with preservation of capital. Under normal market conditions, the Fund will
invest at least 80% of its assets in insured Florida municipal securities. The
Fund commenced investment operations on July 29, 1994 with three classes of
common shares, Class A, Class B and Class C.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Short-term securities with remaining maturities of 60 days or less are valued at
amortized cost, which approximates market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when-issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a separate 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 September 30, 2001, there were no
when-issued or delayed delivery purchase commitments.

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond
premium is amortized and original issue discount is accreted over the expected
life

                                       F-12

of each applicable security. Income and expenses of the Fund are allocated on a
pro rata basis to each class of shares, except for distribution and service fees
and transfer agency costs which are unique to each class of shares.

    In November 2000, the American Institute of Certified Public Accountants
(AICPA) issued a revised version of the AICPA Audit and Accounting Guide for
Investment Companies (the "Guide"). The revised version of the Guide is
effective for annual financial statements issued for fiscal years beginning
after December 15, 2000 and will require investment companies to amortize
premiums and accrete discounts on fixed income securities. The Fund currently
does not accrete market discount on fixed income securities. Upon adoption, the
Fund will be required to record a cumulative effect adjustment to reflect the
accretion of market discount. The adjustment will increase undistributed net
investment income and reduce unrealized appreciation on securities and therefore
will not impact total net assets. As of September 30, 2001, the cumulative
effect adjustment to reflect the accretion of market discount would be $69,237.

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 these losses against any future realized capital
gains. At September 30, 2001, the Fund had an accumulated capital loss
carryforward for tax purposes of $2,671,841 which will expire between September
30, 2005 and September 30, 2009.

    At September 30, 2001, for federal income tax purposes the cost of long-term
investments is $70,035,517, the aggregate gross unrealized appreciation is
$5,010,928 and the aggregate gross unrealized depreciation is $0, resulting in
net unrealized appreciation on long-term investments of $5,010,928.

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually.

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

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

G. EXPENSE REDUCTIONS During the year ended September 30, 2001, the Fund's
custody fee was reduced by $1,781 as a result of credits earned on cash
balances.

2. INVESTMENT ADVISORY AGREEMENT AND
OTHER TRANSACTIONS WITH AFFILIATES

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

<Table>
<Caption>
AVERAGE DAILY NET ASSETS                                      % PER ANNUM
                                                           
First $500 million..........................................     0.50%
Over $500 million...........................................     0.45%
</Table>

    For the year ended September 30, 2001, the Adviser voluntarily waived
$360,882 of its investment advisory fees and assumed $16,338 of the Fund's other
expenses. This waiver is voluntary in nature and can be discontinued at the
Adviser's discretion.

    For the year ended September 30, 2001, the Fund recognized expenses of
approximately $2,000 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Fund, of which a trustee of the
Fund is an affiliated person.

    Under separate Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Fund. The Adviser
allocates the cost of such services to each fund. For the year ended September
30, 2001, the Fund recognized expenses of approximately $45,300 representing Van
Kampen Investment Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, which are reported as part
of "Accounting" and "Legal" expenses, respectively, on the Statement of
Operations.

    Van Kampen Investor Services Inc., an affiliate of the Adviser, serves as
the shareholder servicing agent for the Fund. For the year ended September 30,
2001, the Fund recognized expenses of approximately $23,600. Transfer agency
fees are determined through negotiations with the Fund's Board of Trustees and
are based on competitive market benchmarks.

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

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund and to the extent permitted by the
1940 Act, as amended, invested in the common shares of those funds selected by
the trustees. Investments in such funds of $81,285 are included in "Other"
assets on the Statement of Assets and Liabilities at September 30, 2001.
Appreciation/depreciation and distributions received from these investments are
recorded with an offsetting increase/decrease in the deferred compensation
obligation and do not affect the net asset value of the Fund. Benefits under the
retirement plan are payable upon retirement for a ten-year period and are based
upon each trustee's years of service to the Fund. The maximum annual benefit per
trustee under the plan is $2,500.

(a) As required, effective October 1, 2001, the Fund has adopted the provisions
    of the AICPA Audit and Accounting Guide for Investment Companies and began
    accreting discount on fixed income securities. The effect of this change for
    the six months ended March 31, 2002 was to increase the ratio of net
    investment income to average net asset from 4.33% to 4.36%. Net investment
    income per share and net realized and unrealized gains and losses per share
    were unaffected by the adjustments. Per share, ratios and supplemental data
    for the periods prior to March 31, 2002 have not been restated to reflect
    this change in presentation.

(b) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge of 4.75% or contingent deferred
    sales charge ("CDSC"). On purchases of $1 million or more, a CDSC of 1% may
    be imposed on certain redemptions made within one year of purchase. If the
    sales charges were included, total returns would be lower. These returns
    include combined Rule 12b-1 fees and service fees of up to .25% and do not
    reflect the deduction of taxes that a shareholder would pay on Fund
    distributions or the redemption of Fund shares.

    investment income to average net asset from 3.57% to 3.60%. Net investment
    income per share and net realized and unrealized gains and losses per share

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Insured Tax Free Income Fund (the "Fund") is organized as a series of
the Van Kampen Tax Free Trust (the "Trust"), a Delaware business trust and is
registered as a diversified open-end management investment company under the
Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's
investment objective is to provide investors 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 Fund commenced investment operations on December 14, 1984. The
distribution of the Fund's Class B and Class C Shares commenced on May 3, 1993
and August 13, 1993, respectively.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Short-term securities with remaining maturities of 60 days or less are valued at
amortized cost, which approximates market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when-issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when-issued or delayed delivery
purchase commitments until payment is made. At March 31, 2002, the Fund had
$24,454,897 of when-issued and delayed delivery purchase commitments.

NOTES TO
FINANCIAL STATEMENTS

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond
premium is amortized and original issue discount is accreted over the expected
life of each applicable security. Income and expenses of the Fund are allocated
on a pro rata basis to each class of shares, except for distribution and service
fees and transfer agency costs which are unique to each class of shares.

    As required, effective October 1, 2001, the Fund has adopted the provisions
of the AICPA Audit and Accounting Guide for Investment Companies and began
accreting market discount on fixed income securities. Prior to October 1, 2001,
the Fund did not accrete market discount on fixed income securities. The
cumulative effect of this accounting change had no impact on total net assets of
the Fund, but resulted in a $752,782 increase in cost of securities and a
corresponding $752,782 decrease in net unrealized appreciation based on
securities held by the Fund on October 1, 2001.

    The effect of this change for the six months ended March 31, 2002 was to
increase net investment income by $171,996; decrease net unrealized appreciation
by $125,414, and decrease net realized gains by $46,582. The Statements of
Changes in Net Assets and Financial Highlights for prior periods have not been
restated to reflect this change in presentation.

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 September 30, 2001, the Fund utilized its capital loss carryforward of
$1,991,890.

    At March 31, 2002, for federal income tax purposes, cost of long- and short-
term investments is $1,123,886,386; the aggregate gross unrealized appreciation
is $49,240,745 and the aggregate gross unrealized depreciation is $9,506,353,
resulting in net unrealized appreciation on long- and short-term investments of
$39,734,392.

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.

G. EXPENSE REDUCTIONS During the six months ended March 31, 2002, the Fund's
custody fee was reduced by $25,381 as a result of credits earned on cash
balances.

2. INVESTMENT ADVISORY AGREEMENT AND
OTHER TRANSACTIONS WITH AFFILIATES

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

Over $1.5 billion...........................................       .450%
</Table>

    For the six months ended March 31, 2002, the Fund recognized expenses of
approximately $26,100 representing legal expenses provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Fund, of which a trustee of the
Fund is an affiliated person.

    Under separate Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Fund. The advisor
allocates the cost of such services to each fund. For the six months ended March
31, 2002, the Fund recognized expenses of approximately $66,100 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, which are reported as part
of "Other" and "Legal" expenses, respectively, in the Statement of Operations.

    Van Kampen Investor Services Inc., an affiliate of the Adviser, serves as
the shareholder servicing agent for the Fund. For the six months ended March 31,
2002, the Fund recognized expenses of approximately $334,600. Transfer agency
fees are determined through negotiations with the Fund's Board of Trustees and
are based on competitive market benchmarks.

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

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation

plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund and to the extent permitted by the
1940 Act, as amended, may be invested in the common shares of those funds
selected by the trustees. Investments in such funds of $142,794 are included in
"Other" assets on the Statement of Assets and Liabilities at March 31, 2002.
Appreciation/ depreciation and distributions received from these investments are
recorded with an offsetting increase/decrease in the deferred compensation
obligations and do not affect the net asset value of the Fund. Benefits under
the retirement plan are payable upon retirement for a ten-year period and are
based upon each trustee's years of service to the Fund. The maximum annual
benefit per trustee under the plan is $2,500.

3. CAPITAL TRANSACTIONS

At March 31, 2002, capital aggregated $1,053,678,543, $52,036,737 and

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $320,745,603 and $316,246,640,
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 unrealized
appreciation/depreciation.

    The Fund invests in 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 Rate security is one where the coupon is inversely
indexed to a short-term floating interest rate multiplied by a specified factor.
As the

FINANCIAL STATEMENTS

floating rate rises, the coupon is reduced. Conversely as the floating rate
declines, the coupon is increased. These instruments are typically used by the
Fund to enhance the yield of the portfolio.

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

6. DISTRIBUTION AND SERVICE PLANS

With respect to its Class A Shares, Class B Shares and Class C Shares, the Fund
and its shareholders have adopted a distribution plan pursuant to Rule 12b-1
under the 1940 Act, as amended, and a service plan (collectively the "Plans").
The Plans govern payments for: the distribution of the Fund's Class A Shares,
Class B Shares and Class C Shares; the provision of ongoing shareholder services
with respect to such classes of shares; and maintenance of shareholder accounts
with respect to such classes of shares.

    Annual fees under the Plans of up to .25% of Class A average daily net
assets and 1.00% each of Class B and Class C average daily net assets are
accrued daily. Included in these fees for the six months ended March 31, 2002,
are payments retained by Van Kampen of approximately $349,700 and payments made
to Morgan Stanley DW Inc., an affiliate of the Adviser, of approximately
$36,500.

 ** Non-Annualized

(a) As required, effective October 1, 2001, the Fund has adopted the provisions
    of the AICPA Audit and Accounting Guide for Investment Companies and began
    accreting discount on fixed income securities. These changes for the six
    months ended March 31, 2002 did not affect net investment income per share
    or net realized and unrealized gains and losses per share. However, the
    ratio of net investment income to average net assets increased from 4.37% to
    4.41%. Per share, ratios, and supplemental data for periods prior to March
    31, 2002 have not been restated to reflect this change in presentation.

(b) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge of 4.75% or contingent deferred
    sales charge (CDSC). On purchases of $1 million or more, a CDSC of 1% may be
    imposed on certain redemptions made within one year of purchase. If the
    sales charges were included, total returns would be lower. These returns
    include combined Rule 12b-1 fees and service fees of up to .25% and do not
    reflect the deduction of taxes that a shareholder would pay on Fund
    distributions or the redemption of Fund shares.

(a) As required, effective October 1, 2001, the Fund has adopted the provisions
    of the AICPA Audit and Accounting Guide for Investment Companies and began
    accreting discount on fixed income securities. These changes for the six
    months ended March 31, 2002 did not affect net investment income per share
    or net realized and unrealized gains and losses per share. However, the
    ratio of net investment income to average net assets increased from 3.62% to
    3.66%. Per share, ratios, and supplemental data for periods prior to March
    31, 2002 have not been restated to reflect this change in presentation.

(b) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum CDSC of 4%, charged on certain redemptions
    made within one year of purchase and declining to 0% after the sixth year.
    If the sales charge was included, total returns would be lower. These
    returns include combined Rule 12b-1 fees and service fees of 1% and do not
    reflect the deduction of taxes that a shareholder would pay on Fund
    distributions or the redemption of Fund shares.

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Florida Insured Tax Free Income Fund (the "Fund") is organized as a
series of the Van Kampen Tax Free Trust, a Delaware business trust, and is
registered as a non-diversified, open-end management investment company under
the Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's
investment objective is to provide a high level of current income exempt from
federal income tax and Florida intangible personal property taxes, consistent
with preservation of capital. Under normal market conditions, the Fund will
invest at least 80% of its assets in insured Florida municipal securities. The
Fund commenced investment operations on July 29, 1994 with three classes of
common shares, Class A, Class B, and Class C.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services or dealers are valued at
fair value using procedures established in good faith by the Board of Trustees.
Short-term securities with remaining maturities of 60 days or less are valued at
amortized cost, which approximates market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when-issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a separate 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 March 31, 2002, there were no
when-issued or delayed delivery purchase commitments.

                                      E-11

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security. Income and expenses of the Fund are allocated on a pro rata
basis to each class of shares, except for distribution and service fees and
transfer agency costs which are unique to each class of shares.

    As required, effective October 1, 2001, the Fund has adopted the provisions
of the AICPA Audit and Accounting Guide for Investment Companies and began
accreting discount on fixed income securities. Prior to October 1, 2001, the
Fund did not accrete discount on fixed income securities. The cumulative effect
of this accounting change had no impact on total net assets of the Fund, but
resulted in a $69,236 increase in cost of securities and a corresponding $69,236
decrease in net unrealized appreciation, based on securities held by the Fund on
October 1, 2001.

    The effect of this change for the six months ended March 31, 2002 was to
increase net investment income by $15,592; increase net unrealized appreciation
by $4,917, and decrease net realized gains by $20,509. The Statement of Changes
in Net Assets and Financial Highlights for prior periods have not been restated
to reflect this change in presentation.

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 these losses against any future realized capital
gains. At September 30, 2001 the Fund had an accumulated capital loss
carryforward for tax purposes of $2,671,841 which will expire between September
30, 2005 and September 30, 2009.

    At March 31, 2002, for federal income tax purposes the cost of long- and
short-term investments is $76,103,830, the aggregate gross unrealized
appreciation is $2,877,101 and the aggregate gross unrealized depreciation is
$349,841, resulting in net unrealized appreciation on long- and short-term
investments of $2,527,260.

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 EXPENSE The Fund typically invests in insured bonds. Any portfolio
securities not specifically covered by a primary insurance policy are insured

                                      E-12

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.

G. EXPENSE REDUCTIONS During the six months ended March 31, 2002, the Fund's
custody fee was reduced by $846 as a result of credits earned on cash balances.

2. INVESTMENT ADVISORY AGREEMENT AND
OTHER TRANSACTIONS WITH AFFILIATES

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

<Table>
<Caption>
                  AVERAGE DAILY NET ASSETS                      % PER ANNUM
                                                             
First $500 million..........................................       .50%
Over $500 million...........................................       .45%
</Table>

    For the six months ended March 31, 2002, the Adviser voluntarily waived
$203,955 of its investment advisory fees and assumed $9,225 of the Fund's other
expenses. This waiver is voluntary in nature and can be discontinued at the
Adviser's discretion.

    For the six months ended March 31, 2002, the Fund recognized expenses of
approximately $2,800 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Fund, of which a trustee of the
Fund is an affiliated person.

    Under separate Accounting Services and Legal Services agreements, the
Adviser provides accounting and legal services to the Fund. The Adviser
allocates the cost of such services to each fund. For the six months ended March
31, 2002, the Fund recognized expenses of approximately $28,500 representing Van
Kampen Investment Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, which are reported as part
of "Accounting" and "Legal" expenses, respectively, on the Statement of
Operations.

    Van Kampen Investor Services Inc., an affiliate of the Adviser, serves as
the shareholder servicing agent for the Fund. For the six months ended March 31,
2002, the Fund recognized expenses of approximately $21,700. Transfer agency
fees are determined through negotiations with the Fund's Board of Trustees and
are based on competitive market benchmarks.

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

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation.
Amounts deferred are retained by the Fund and to the extent permitted by the
1940 Act, as amended, invested in the common shares of those funds selected by
the trustees. Investments in such funds of $86,755 are included in "Other"
assets on the Statement of Assets and Liabilities at March 31, 2002.
Appreciation/depreciation and distributions received from these investments are
recorded with an offsetting increase/decrease in the deferred compensation
obligation and do not affect the net asset value of the Fund. Benefits under the
retirement plan are payable upon retirement for a ten-year period and are based
upon each trustee's years of service to the Fund. The maximum annual benefit per
trustee under the plan is $2,500.

3. CAPITAL TRANSACTIONS

At March 31, 2002, capital aggregated $41,208,223, $33,873,949 and $5,745,832

(1) The proforma statements are presented as if the Reorganization was effective
March 31, 2002. The pro forma statements give the effect to the proposed
exchange of Van Kampen Insured Tax Free Income Fund for assets and liabilities
of the Van Kampen Florida Insured Tax Free Income Fund, with the Insured Tax
Free Income Fund being the surviving entity. The proposed transaction will be
accounted for in accordance with accounting principles generally accepted in the
United States of America, as a tax-free reorganization. The historical cost
basis of the investments is carried over to the surviving entity. It is not
anticipated that the Van Kampen Insured Tax Free Income Fund will sell any
securities of the Van Kampen Florida Insured Tax Free Income Fund acquired in
the reorganization other than in the ordinary course of business.

(2) The pro forma statements presume the issuance by the Van Kampen Insured Tax
Free Income Fund of approximately 2,245,000 Class A Shares, 1,884,000 Class B
Shares and 306,000 Class C Shares in exchange for the assets and liabilities of
the Van Kampen Florida Insured Tax Free Income Fund.


(3) A non-recurring cost associated with this transaction of approximately
$201,000 will be incurred. Approximately $155,000 will be borne by Van Kampen
and approximately $46,000 or $0.00073 per share will be borne by the
shareholders of the Van Kampen Insured Tax Free Income Fund.

PART C: OTHER INFORMATION

     ITEM 15.  INDEMNIFICATION

     Pursuant to Del. Code Ann. Title 12 Section 3817, a Delaware business trust
may provide in its governing instrument for the indemnification of its officers
and trustees from and against any and all claims and demands whatsoever.

     Reference is made to Article 8, Section 8.4 of the Registrant's Agreement
and Declaration of Trust. Article 8, Section 8.4 of the Agreement and
Declaration of Trust provides that each officer and trustee of the Registrant
shall be indemnified by the Registrant against all liabilities incurred in
connection with the defense or disposition of any action, suit or other
proceeding, whether civil or criminal, in which the officer or trustee may be or
may have been involved by reason of being or having been an officer or trustee,
except that such indemnity shall not protect any such person against a liability
to the Registrant or any shareholder thereof to which such person would
otherwise be subject by reason of (i) not acting in good faith in the reasonable
belief that such person's actions were not in the best interests of the Trust,
(ii) having acted with willful misfeasance, bad faith, gross negligence or
reckless disregard of the duties involved in the conduct of his or her office or
(iii) for a criminal proceeding had reasonable cause to believe the conduct was
unlawful (collectively, "Disabling Conduct"). Absent a court determination that
an officer or trustee seeking indemnification was not liable on the merits or
guilty of Disabling Conduct in the conduct of his or her office, the decision by
the Registrant to indemnify such person must be based upon the reasonable
determination of independent counsel or non-party independent trustees, after
review of the facts, that such officer or trustee is not guilty of Disabling
Conduct in the conduct of his or her office.

     The Registrant has purchase insurance on behalf of its officers and
trustees protecting such persons from liability arising from their activities as
officers or trustees of the Registrant. The insurance does not protect or
purport to protect such persons from liability to the Registrant or to its
shareholders to which such officers or trustee would otherwise be subject by
reason of willful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of their office.

     Conditional advancing of indemnification monies may be made if the trustee
or officer undertakes to repay the advance unless it is ultimately that he or
she is entitled to the indemnification and only if the following conditions are
met: (1) the trustee or officer provides security for the undertaking; (2) the
Registrant is insured against losses arising from lawful advances; or (3) a
majority of a quorum of the Registrant's disinterested, non-party trustees, or
an independent legal counsel in a written opinion, shall determine, based upon a
review of readily available facts, that a recipient of the advance ultimately
will be found entitled to indemnification.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Securities Act") may be permitted to trustees, officers and
controlling persons of the Registrant pursuant to the foregoing provisions or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by the trustee, officer,
or controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such trustee, officer or controlling person
in connection with the shares being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

     Pursuant to Section 7 of the Distribution and Service Agreement, the
Registrant agrees to indemnify and hold harmless Van Kampen Funds Inc. (the
"Distributor") and each of its trustees and officers and each person if any, who
controls the Distributor within the meaning of Section 15 of the 1933 Act
against any loss, liability, claim damages or expense (including the reasonable
cost of investing or defending any alleged loss, liability, claim, damages, or
expense and reasonable counsel fees) arising by reason of any person acquiring
any shares, based upon the ground that the Registration Statement, prospectus,
shareholder reports or other

                                       C-1


information filed or made public by the Registrant (as from time to time
amended) included an untrue statement of a material fact or omitted to state a
material fact required to be stated or necessary in order to make the statements
not misleading under the 1933 Act, or any other statute or the common law. The
Registrant does not agree to indemnify the Distributor or hold it harmless to
the extent that the statement or omission was made in reliance upon, and in
conformity with, information furnished to the Registrant by or on behalf of the
Distributor. In no case is the indemnity of the Registrant in favor of the
Distributor or any person indemnified to be deemed to protect the Distributor or
any person against any liability to the Fund or its security holders to which
the Distributor or any person against any liability to the Fund or its security
holders to which the Distributor or such person would otherwise be subject by
reason of willful misfeasance, bad faith or gross negligence in the performance
of its duties or by reason of its reckless disregard of its obligations and
duties under the agreement.

     Pursuant to the agreement by which Van Kampen Investor Services Inc.
("Investor Services") is appointed transfer agent of the Fund, the Registrant
agrees to indemnify and hold Investor Services harmless against any losses,
damages, costs, charges, payments, liabilities and expenses (including
reasonable counsel fees) arising out of or attributable to:

          (1) the performance of Investor Services under the agreement provided
     that Investor Services acted in good faith with due diligence and without
     negligence or willful misconduct.

          (2) reliance by Investor Services on, or reasonable use by, Investor
     Services of information, records and documents which have been prepared on
     behalf of, or have been furnished by, the Fund, or the carrying out by
     Investor Services of any instructions or requests of the Fund.

          (3) the offer or sale of the Fund's shares in violation of any federal
     or state law or regulation or ruling by any federal agency unless such
     violation results from any failure by Investor Services to comply with
     written instructions from the Fund that such offers or sales were not
     permitted under such law, rule or regulation.

          (4) the refusal of the Fund to comply with terms of the agreement, or
     the Fund's lack of good faith, negligence or willful misconduct or breach
     of any representation or warranty made by the Fund under the agreement
     provided that if the reason for such failure is attributable to any action
     of the Fund's investment adviser or distributor or any person providing
     accounting or legal services to the Fund, Investor Services only will be
     entitled to indemnification if such entity is otherwise entitled to the
     indemnification from the Fund.
