PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF
FUTURE RESULTS, AND CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN THE FIGURES
SHOWN. FOR THE MOST RECENT MONTH-END PERFORMANCE FIGURES, PLEASE VISIT
VANKAMPEN.COM OR SPEAK WITH YOUR FINANCIAL ADVISOR. INVESTMENT RETURNS AND
PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE
OR LESS THAN THEIR ORIGINAL COST.

The returns shown in this report do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Performance of share classes will vary due to differences in sales charges and
expenses. Average annual total return with sales charges includes payment of the
maximum sales charge of 4.75 percent for Class A shares, a contingent deferred
sales charge of 4.00 percent for Class B shares (in year one and declining to
zero after year six), a contingent deferred sales charge of 1.00 percent for
Class C shares in year one and combined Rule 12b-1 fees and service fees of up
to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C
shares. The since inception and 10-year returns for Class B shares reflect their
conversion into Class A shares eight years after purchase. The since inception
returns for Class C shares reflect their conversion into Class A shares ten
years after purchase. Class I shares are available for purchase exclusively by
investors through (i) tax-exempt retirement plans with assets of at least $1
million (including 401(k) plans, 457 plans, employer-sponsored 403(b) plans,
profit sharing and money purchase plans, defined benefit plans and non-qualified
deferred compensation plans), (ii) fee-based investment programs with assets of
at least $1 million, (iii) qualified state tuition plan (529 plan) accounts,
(iv) institutional clients with assets of at least $1 million and (v) certain
Van Kampen investment companies. Class I shares are offered without any sales
charges on purchases or sales and do not include combined Rule 12b-1 fees and
service fees. Figures shown above assume reinvestment of all dividends and
capital gains. Periods less than one year are not annualized.

SEC yield is a calculation for determining the amount of portfolio income,
excluding non-income items as prescribed by the SEC. Yields are subject to
change.

The Lehman Brothers Municipal Bond Index is generally representative of
investment-grade, tax exempt bonds. The index does not include any expenses,
fees or sales charges, which would lower performance. The index is unmanaged and
should not be considered an investment. It is not possible to invest directly in
an index.

Fund Report

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2008

MARKET CONDITIONS

The financial markets experienced significant volatility throughout the six-
month reporting period as many large banks and financial firms began writing
down mortgage-related losses, and liquidity and credit availability became even
more restricted. At the same time, the pace of economic growth began to slow,
with gross domestic product (GDP) growth measuring an anemic 0.6 percent for the
fourth quarter of 2007. As weaker economic data was released in the first
quarter of 2008, fears of recession grew and consumer confidence waned,
prompting investors to continue to seek out the relative safety of high-quality
Treasury securities over other sectors of the fixed income market.

The municipal bond market faced additional headwinds as various monoline bond
insurers experienced credit quality downgrades and the auction rate and variable
rate markets deteriorated. As a result, the municipal market underperformed
Treasuries for the overall period, with municipal bond prices reaching
historically attractive levels relative to Treasury bonds in the first quarter
of 2008. While yields on short-dated municipal securities declined, yields on
intermediate- and long-dated securities rose, leading to the steepest yield
curve in the past four years as the spread between one-year and 30-year
maturities reached 343 basis points. After a record year for new municipal bond
issuance in 2007, the amount of new issues coming to market in the first quarter
of 2008 declined by roughly 25 percent due in large part to a substantial drop
in refunding issuance. Insured bond issuance declined dramatically in the first
quarter, from approximately 50 percent to 25 percent of total new-issue supply.

The Federal Reserve (the "Fed") took various steps to ease the liquidity crisis
and boost the economy during the period. Not only did the Fed reduce the target
federal funds rate from 4.75 percent to 2.25 percent by the end of the period,
but in an unprecedented move, it granted primary brokerage firms access to its
discount window and loosened its collateral requirements, extending loans of
Treasury securities in exchange for lower quality, less liquid securities.
Finally, in the biggest headline event, the Fed arranged and supported JP Morgan
Chase's purchase of Bear Stearns, which was viewed by many as necessary to avoid
serious market repercussions had the firm failed.

The performance for the four share classes varies because each has different
expenses. The Fund's total return figures assume the reinvestment of all
distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and
index definition.

Although the municipal bond market rebounded in the last month of the reporting
period and outperformed Treasuries, it was a difficult period overall,
particularly for the insured sector as the credit downgrades of various monoline
insurers put considerable pressure on prices. Rising rates in the intermediate
and long maturity portions of the yield curve also hurt the performance of these
more interest-rate sensitive securities. Given that the benchmark Lehman
Brothers Municipal Bond Index contains no insured bonds, the Fund's approximate
85 percent allocation to insured securities was a primary contributor to its
relative underperformance.

The Fund's holdings in tobacco, health care, and housing bonds also detracted
from performance. These positions were held primarily in the form of inverse
floating-rate securities* which are uninsured but still investment-grade issues.
Although these higher yielding securities served to enhance the Fund's income
and diversification, spread widening in all three sectors hurt their
performance.

We continued to favor longer maturity bonds in an effort to capture higher
yields, which resulted in a longer duration (a measure of interest-rate
sensitivity) for the portfolio. To reduce that duration somewhat, we used a
Treasury futures hedge for much of the period. Unfortunately, rising rates on
the long end of the curve coupled with the Treasury market rally caused this
positioning to detract from performance. We did, however, unwind the hedge,
investing the proceeds in auction rate securities for their favorable yields.

Holdings in other sectors, however, contributed positively to performance.
Specifically, pre-refunded, health care, public power, and water and sewer bonds
were additive to returns.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the Fund in
the future.

*An inverse floating-rate security, or "inverse floater", is a variable rate
security whose coupon rate changes in the opposite direction from the change in
the reference rate used to calculate the coupon rate.

       Each Van Kampen fund provides a complete schedule of portfolio holdings
       in its semiannual and annual reports within 60 days of the end of the
       fund's second and fourth fiscal quarters. The semiannual reports and the

       mailings to the same address. The Fund delivers a single copy of certain
       shareholder documents to investors who share an address, even if the
       accounts are registered under different names. The Fund's prospectuses
       and shareholder reports (including annual privacy notices) will be
       delivered to you in this manner indefinitely unless you instruct us
       otherwise. You can request multiple copies of these documents by either

       Box 219286, Kansas City, MO 64105. Once Investor Services has received

PROXY VOTING POLICY AND PROCEDURES AND PROXY VOTING RECORD

       You may obtain a copy of the Fund's Proxy Voting Policy and Procedures
       without charge, upon request, by calling toll free (800) 847-2424 or by
       visiting our Web site at www.vankampen.com. It is also available on the
       Securities and Exchange Commission's Web site at http://www.sec.gov.

       You may obtain information regarding how the Fund voted proxies relating
       to portfolio securities during the most recent twelve-month period ended
       June 30 without charge by visiting our Web site at www.vankampen.com.
       This information is also available on the Securities and Exchange
       Commission's Web site at http://www.sec.gov.

                                                                               7


Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and C Shares;
and redemption fees; and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees; and other Fund expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 10/1/07 - 3/31/08.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing cost of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or contingent deferred sales charges or redemption fees.
Therefore, the second line of the table is useful in comparing ongoing costs
only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
cost would have been higher.

VAN KAMPEN INSURED TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED)

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, a Delaware statutory 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 with a high level of current income exempt
from federal income taxes, with liquidity and safety of principal, primarily
through investment in a diversified portfolio of insured municipal securities.
The Fund commenced investment operations on December 14, 1984. The Fund offers
Class A Shares, Class B Shares, Class C Shares and Class I Shares. Each class of
shares differs by its initial sales load, contingent deferred sales charges, the
allocation of class-specific expenses and voting rights on matters affecting a
single class.

    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 U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the last reported 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. Futures contracts are valued at the settlement price established each
day on the exchange on which they are traded. Interest rate swaps are valued
using market quotations obtained from brokers. 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
segregate assets with the custodian 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, 2008, the Fund had $7,445,850 of when-issued and
delayed delivery purchase commitments.

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
incremental transfer agency costs which are unique to each class of shares.

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M 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 adopted the provisions of the Financial Accounting Standards Board ("FASB")
Interpretation No. 48 ("FIN 48") Accounting for Uncertainty in Income Taxes on
March 31, 2008. FIN 48 sets forth a minimum threshold for financial statement
recognition of the benefit of a tax position taken or expected to be taken in a
tax return. The implementation of FIN 48 did not result in any unrecognized tax
benefits in the accompanying financial statements. If applicable, the Fund
recognizes interest accrued related to unrecognized tax benefits in "Interest
Expense" and penalties in "Other" expenses on the Statement of Operations. The
Fund files tax returns with the U.S. Internal Revenue Service, New York and
various states. Generally, each of the tax years in the four year period ended
September 30, 2007, remains subject to examination by taxing authorities.

    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, 2007, the Fund had an accumulated capital loss
carryforward for tax purposes of $210,390 which will expire on September 30,
2015.

    At March 31, 2008, the cost and related gross unrealized appreciation and
depreciation were as follows:

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 at least annually. Distributions from net realized gains for book
purposes may include short-term capital gains and a portion of futures gains,
which are included in ordinary income for tax purposes.

    The tax character of distributions paid during the year ended September 30,
2007:

</Table>

    As of September 30, 2007, the components of distributable earnings on a tax
basis were as follows:

Undistributed ordinary income...............................  $   35,181
Undistributed tax-exempt income.............................   3,433,086

    Net realized gains or losses may differ for financial reporting and tax
purposes primarily as a result of gains or losses recognized on securities for
tax purposes but not for book.

                                                                              35

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

G. CREDITS EARNED ON CASH BALANCES During the six months ended March 31, 2008,
the Fund's custody fee was reduced by $34,185 as a result of credits earned on
cash balances.

H. FLOATING RATE NOTE OBLIGATIONS RELATED TO SECURITIES HELD The Fund enters
into transactions in which it transfers to dealer trusts fixed rate bonds in
exchange for cash and residual interest in the dealer trusts' assets and cash
flows, which are in the form of inverse floating rate investments. The dealer
trusts fund the purchases of the fixed rate bonds by issuing floating rate notes
to third parties and allowing the Fund to retain residual interests in the
bonds. The Fund enters into shortfall agreements with the dealer trusts, which
commit the Fund to pay the dealer trusts, in certain circumstances, the
difference between the liquidation value of the fixed rate bonds held by the
dealer trusts and the liquidation value of the floating rate notes held by third
parties, as well as any shortfalls in interest cash flows. The residual
interests held by the Fund (inverse floating rate investments) include the right
of the Fund (1) to cause the holders of the floating rate notes to tender their
notes at par at the next interest rate reset date, and (2) to transfer the
municipal bond from the dealer trusts to the Fund, thereby collapsing the dealer
trusts. The Fund accounts for the transfer of bonds to the dealer trusts as
secured borrowings, with the securities transferred remaining in the Fund's
investments assets, and the related floating rate notes reflected as Fund
liabilities under the caption "Floating Rate Note Obligations" on the Statement
of Assets and Liabilities. The Fund records the interest income from the fixed
rate bonds under the caption "Interest" and records the expenses related to
floating rate note obligations and any administrative expenses of the dealer
trusts under the caption "Interest and Residual Trust Expenses" on the Fund's
Statement of Operations. The notes issued by the dealer trusts have interest
rates that reset weekly and the floating rate note holders have the option to
tender their notes to the dealer trusts for redemption at par at each reset
date. At March 31, 2008, Fund investments with a value of $253,622,928 are held
by the dealer trusts and serve as collateral for the $184,920,000 in floating
rate notes outstanding at that date. Contractual maturities of the floating rate
notes and interest rates in effect at March 31, 2008 are presented on the
Portfolio of Investments. The average floating rate notes outstanding and
average interest and fee rate related to residual interests during the six
months ended March 31, 2008 were $214,900,714 and 4.44%, respectively.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset
Management (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

Next $500 million...........................................    0.475%
Over $1.5 billion...........................................    0.450%
</Table>

    For the six months ended March 31, 2008, the Fund recognized expenses of
approximately $18,600 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such
firm and he and his law firm provide legal services as legal counsel to the
Fund.

    Under separate Legal Services, Accounting Services and Chief Compliance
Officer (CCO) Employment agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Fund. The costs of
these services are allocated to each fund. For the six months ended March 31,
2008, the Fund recognized expenses of approximately $48,700 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, as well as the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Professional Fees" on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Accounting and Administrative Expenses" on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the six months ended
March 31, 2008, the Fund recognized expenses of approximately $166,600
representing transfer agency fees paid to VKIS and its affiliates. The transfer
agency fees are determined through negotiations with the Fund's Board of
Trustees.

    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 also
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 $272,637 are included in
"Other" assets on the Statement of Assets and Liabilities at March 31, 2008.
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.

    For the six months ended March 31, 2008, Van Kampen, as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $46,600 and

                                                                              37

6. 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.

 38


VAN KAMPEN INSURED TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

    The Fund may use derivative instruments for a variety of reasons, 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 holdings, including derivative instruments, are marked to
market each day with the change in value reflected in unrealized
appreciation/depreciation. Upon disposition, a realized gain or loss is
recognized accordingly, except when exercising an option contract or taking
delivery of a security underlying a futures contract. In this instance, the
recognition of gain or loss is postponed until the disposal of the security
underlying the futures contract.

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

A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in exchange traded futures contracts on U.S. Treasury
Bonds or Notes for duration and risk management purposes and typically closes
the contract prior to the delivery date. Upon entering into futures contracts,
the Fund maintains an amount of cash or liquid securities with a value equal to
a percentage of the contract amount with either a futures commission merchant
pursuant to rules and regulations promulgated under the 1940 Act, as amended, or
with its custodian in an account in the broker's name. This amount is known as
initial margin. During the period the futures contract is open, payments are
received from or made to the broker based upon changes in the value of the
contract (the variation margin). The risk of loss associated with a futures
contract is in excess of the variation margin reflected on the Statement of
Assets and Liabilities.

    Transactions in futures contracts for the six months ended March 31, 2008,
were as follows:

</Table>

B. INVERSE FLOATING RATE INVESTMENTS The Fund may invest a portion of its assets
in inverse floating rate instruments, either through outright purchases of
inverse floating rate securities or through the transfer of bonds to a dealer
trust in exchange for cash and residual interests in the dealer trust. These
investments are typically used by the Fund in seeking to enhance the yield of
the portfolio. These instruments typically involve greater risks than a fixed
rate municipal bond. In particular, these instruments are acquired through
leverage or may have leverage embedded in them and therefore involve many of the
risks associated with leverage. Leverage is a speculative technique that may
expose the Fund to greater risk and increased costs. Leverage may cause the
Fund's net asset value to be more volatile than if it had not been leveraged
because leverage tends to magnify the effect of any increases or decreases in
the value of the Fund's portfolio securities. The use of leverage may also cause
the Fund to liquidate portfolio positions when it may not be advantageous to do
so in order to satisfy its obligations with respect to inverse floating rate
instruments.

C. INTEREST RATE SWAPS The Fund may enter into forward interest rate swap
transactions intended to help the Fund manage its overall interest rate
sensitivity, either shorter or longer, generally to more closely align the
Fund's interest rate sensitivity with that of the broader municipal market.
Forward interest rate swap transactions involve the Fund's agreement with a
counterparty to pay, in the future, a fixed or variable rate payment in exchange
for the counterparty paying the Fund a variable or fixed rate payment, the
accruals for which would begin at a specified date in the future (the "effective
date"). The amount of the payment obligation is based on the notional amount of
the forward swap contract and the termination date of the swap (which is akin to
a bond's maturity). The value of the Fund's swap commitment would increase or
decrease based primarily on the extent to which long-term interest rates for
bonds having a maturity of the swap's termination date increases or decreases.
The Fund may terminate a swap contract prior to the effective date, at which
point a realized gain or loss is recognized. When a forward swap is terminated,
it ordinarily does not involve the delivery of securities or other underlying
assets or principal, but rather is settled in cash on a net basis. The Fund
intends, but is not obligated, to terminate its forward swaps before the
effective date. Accordingly, the risk of loss with respect to the swap
counterparty on such transactions is limited to the credit risk associated with
a counterparty failing to honor its commitment to pay any realized gain to the
Fund upon termination. To reduce such credit risk, all counterparties are
required to pledge collateral daily (based on the daily valuation of each swap)
on behalf of the Fund with a value approximately equal to the amount of any
unrealized gain. Reciprocally, when the Fund has an unrealized loss on a swap
contract, the Fund has instructed the custodian to pledge cash or liquid
securities as collateral with a value approximately equal to the amount of the
unrealized loss. Collateral pledges are monitored and subsequently adjusted if
and when the swap valuations fluctuate. Restricted cash, if any, for segregating
purposes is shown on the Statement of Assets and Liabilities.

7. DISTRIBUTION AND SERVICE PLANS

Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"),
an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant
to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively,
the "Plans") for Class A Shares, Class B Shares and Class C Shares to compensate
the Distributor for the sale, distribution, shareholder servicing and
maintenance of shareholder accounts for these shares. Under the Plans, the Fund
will incur annual fees of up to .25% of Class A average daily net assets and up
to 1.00% each of Class B and Class C average daily net assets. These fees are
accrued daily and paid to the Distributor monthly.

    The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed receivable") was approximately $719,900 and $56,000
for Class B and Class C Shares, respectively. These amounts may be recovered
from future payments under the distribution plan or CDSC. To the extent the
unreimbursed receivable has been fully recovered, the distribution fee is
reduced.

8. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

9. ACCOUNTING PRONOUNCEMENT

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. As of March 31, 2008, the Adviser does not believe the adoption of
SFAS 157 will impact the amounts reported in the financial statements, however,
additional disclosures will be required about the inputs used to develop the
measurements of fair value and the effect of certain measurements reported on
the Statement of Operations for a fiscal period.

                                                                              41

Average annual total return with sales charges includes payment of the maximum
sales charge of 4.75 percent for Class A shares, a contingent deferred sales
charge of 4.00 percent for Class B shares (in year one and declining to zero
after year six), a contingent deferred sales charge of 1.00 percent for Class C
shares in year one and combined Rule 12b-1 fees and service fees of up to 0.25
percent for Class A shares and up to 1.00 percent for Class B and C shares. The
since inception and 10-year returns for Class B shares reflect the conversion of
Class B shares into Class A shares seven years after purchase. The since
inception returns for Class C shares reflect the conversion of Class C shares
into Class A shares ten years after purchase. Class I shares are available for
purchase exclusively by investors through (i) tax-exempt retirement plans with
assets of at least $1 million (including 401(k) plans, 457 plans, employer-
sponsored 403(b) plans, profit sharing and money purchase plans, defined benefit
plans and non-qualified deferred compensation plans), (ii) fee-based investment
programs with assets of at least $1 million, (iii) qualified state tuition plan
(529 plan) accounts, (iv) institutional clients with assets of at least $1
million and (v) certain Van Kampen investment companies. Class I shares are
offered without any sales charges on purchases or sales and do not include
combined rule 12b-1 fees and service fees. Figures shown above assume
reinvestment of all dividends and capital gains. Periods less than one year are
not annualized. SEC yield is a calculation for determining the amount of
portfolio income, excluding non-income items as prescribed by the SEC. Yields
are subject to change.

The Lehman Brothers Municipal Bond Index is generally representative of
investment-grade, tax-exempt bonds. The index does not include any expenses,
fees or sales charges, which would lower performance. The index is unmanaged and
should not be considered an investment. It is not possible to invest directly in
an index.

Fund Report

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2008

MARKET CONDITIONS

The financial markets experienced significant volatility throughout the
six-month reporting period, as many large banks and financial firms began
writing down mortgage-related losses, and liquidity and credit availability
became even more restricted. At the same time, the pace of economic growth began
to slow, with gross domestic product (GDP) growth measuring an anemic 0.6
percent for the fourth quarter of 2007. As weaker economic data was released in
the first quarter of 2008, fears of recession grew and consumer confidence
waned, prompting investors to continue to seek out the relative safety of high
quality Treasury securities over other sectors of the fixed income market.

The municipal bond market faced additional headwinds as various monoline bond
insurers experienced credit rating downgrades and the auction rate and variable
rate markets deteriorated. As a result, the municipal market underperformed
Treasuries for the overall period, with municipal bond prices reaching
historically attractive levels relative to Treasury bonds in the first quarter
of 2008. While yields on short-dated municipal securities declined, yields on
intermediate- and long-dated securities rose, leading to the steepest yield
curve in the past four years as the spread between one-year and 30-year
maturities reached 343 basis points. After a record year for new municipal bond
issuance in 2007, the amount of new issues coming to market in the first quarter
of 2008 declined by roughly 25 percent, due in large part to a substantial drop
in refunding issuance.

The Federal Reserve (the "Fed") took various steps to ease the liquidity crisis
and boost the economy during the period. Not only did the Federal Open Market
Committee reduce the target federal funds rate from 4.75 percent to 2.25 percent
by the end of the period, but in an unprecedented move, the Fed granted primary
brokerage firms access to its discount window and loosened its collateral
requirements, extending loans of Treasury securities in exchange for lower
quality, less liquid securities. Finally, in the biggest headline event, the Fed
arranged and supported JP Morgan Chase's purchase of Bear Stearns, which was
viewed by many as necessary to avoid serious market repercussions had the firm
failed.

The performance for the four share classes varies because each has different
expenses. The Fund's total return figures assume the reinvestment of all
distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and
index definition.

Although the municipal market rebounded in the last month of the reporting
period and outperformed Treasuries, it was an extremely difficult period
overall, particularly for higher-yielding, lower-rated bonds as the market-wide
flight to quality put considerable pressure on their prices. The Fund invests
approximately 50 percent of its assets in lower- and non-rated securities,
whereas the Lehman Brothers Municipal Bond Index is comprised entirely of
investment-grade issues. As such, the Fund's allocation to high yield bonds was
the primary reason for its relative underperformance.

Holdings in various sectors also detracted from relative performance. In
particular, the Fund's allocations to health care, life care, and special tax
district bonds held back returns as spreads in the sectors moved considerably
wider for the period. Additionally, spread widening in the tobacco sector
hindered performance, though to a lesser extent given the Fund's relatively
small allocation to these securities. The Fund's holdings in inverse
floating-rate securities*, some of which had exposure to the insured municipal
market, also held back returns. Inverse floating-rate securities offer the
benefit of higher yields but are also highly sensitive to interest rate changes.
As such, the rise in municipal interest rates during the period, coupled with
the downgrading of various monoline bond insurers, hurt the performance of these
securities. We did, however, trim the Fund's allocation here, which helped to
reduce volatility in the portfolio and to manage shareholder cash flows.

The Fund's holdings in pre-refunded bonds, however, were additive to returns for
the period. These short-maturity securities performed well as declining yields
on the front end of the curve boosted prices.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the Fund in
the future.

*An inverse floating-rate security, or "inverse floater", is a variable rate
security whose coupon rate changes in the opposite direction from the change in
the reference rate used to calculate the coupon rate.

       otherwise. You can request multiple copies of these documents by either

PROXY VOTING POLICY AND PROCEDURES AND PROXY VOTING RECORD

       You may obtain a copy of the Fund's Proxy Voting Policy and Procedures
       without charge, upon request, by calling toll free (800) 847-2424 or by
       visiting our Web site at www.vankampen.com. It is also available on the

       June 30 without charge by visiting our Web site at www.vankampen.com.
       This information is also available on the Securities and Exchange
       Commission's Web site at http://www.sec.gov.

                                                                               7


Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and Class C
Shares; and redemption fees; and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees; and other Fund expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 10/1/07 - 3/31/08.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing cost of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or contingent deferred sales charges or redemption fees.
Therefore, the second line of the table is useful in comparing ongoing costs
only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
cost would have been higher.

VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Strategic Municipal Income Fund (the "Fund") is organized as a series
of the Van Kampen Tax Free Trust, a Delaware statutory 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 seek to provide investors a high level of current income exempt
from federal income tax primarily through investment in a diversified portfolio
of medium- and lower-grade municipal securities. The Fund commenced investment
operations on June 28, 1985. The Fund offers Class A Shares, Class B Shares,
Class C Shares and Class I Shares. Each class of shares differs by its initial
sales load, contingent deferred sales charges, the allocation of class-specific
expenses and voting rights on matters affecting a single class.

    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 U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION 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.
Futures contracts are valued at the settlement price established each day on the
exchange on which they are traded. 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.
Legal expenditures that are expected to result in the restructuring of or a plan
of reorganization for an investment are recorded as realized losses. 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 segregate
assets with the custodian 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, 2008, the Fund had $22,343,635 of when-issued or delayed
delivery purchase commitments.

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
incremental transfer agency costs which are unique to each class of shares.

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M of the Internal Revenue Code applicable to regulated investment
companies

                                                                              53

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

and to distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required. The Fund adopted
the provisions of the Financial Accounting Standards Board ("FASB")
Interpretation No. 48 ("FIN 48") Accounting for Uncertainty in Income Taxes on
March 31, 2008. FIN 48 sets forth a minimum threshold for financial statement
recognition of the benefit of a tax position taken or expected to be taken in a
tax return. The implementation of FIN 48 did not result in any unrecognized tax
benefits in the accompanying financial statements. If applicable, the Fund
recognizes interest accrued related to unrecognized tax benefits in "Interest
Expense" and penalties in "Other" expenses on the Statement of Operations. The
Fund files tax returns with the U.S. Internal Revenue Service and various
states. Generally, each of the tax years in the four year period ended September
30, 2007, remains subject to examination by taxing authorities.

    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, 2007, the Fund had an accumulated capital loss
carryforward for tax purposes of $121,633,269, which will expire according to
the following schedule.

into transactions in which it transfers to dealer trusts fixed rate bonds in
exchange for cash and residual interest in the dealer trusts' assets and cash
flows, which are in the form of inverse floating rate investments. The dealer
trusts fund the purchases of the fixed rate bonds by issuing floating rate notes
to third parties and allowing the Fund to retain residual interests in the
bonds. The Fund enters into shortfall agreements with the dealer trusts, which
commit the Fund to pay the dealer trusts, in certain circumstances, the
difference between the liquidation value of the fixed rate bonds held by the
dealer trusts and the liquidation value of the floating rate notes held by third
parties, as well as any shortfalls in interest cash flows. The residual
interests held by the Fund (inverse floating rate investments) include the right
of the Fund (1) to cause the holders of the floating rate notes to tender their
notes at par at the next interest rate reset date, and (2) to transfer the
municipal bond from the dealer trusts to the Fund, thereby collapsing the dealer
trusts. The Fund accounts for the transfer of bonds to the dealer trusts as
secured borrowings, with the securities transferred remaining in the Fund's
investments assets, and the related floating rate notes reflected as Fund
liabilities under the caption "Floating Rate Note Obligations" on the Statement
of Assets and Liabilities. The Fund records the interest income from the fixed
rate bonds under the caption "Interest" and records the expenses related to
floating rate note obligations and any administrative expenses of the dealer
trusts under the caption "Interest and Residual Trust Expenses" on the Fund's
Statement of Operations. The notes issued by the dealer trust have interest
rates that reset weekly and the floating rate note holders have the option to
tender their notes to the dealer trusts for redemption at par at each reset
date. At March 31, 2008, Fund investments with a value of $152,454,469 are held
by the dealer trusts and serve as collateral for the $101,600,000 in floating
rate notes outstanding at that date. Contractual maturities of the floating rate
notes and interest rates in effect at March 31, 2008 are presented on the
Portfolio of Investments. The average floating rate notes outstanding and
average annual interest and fee rate related to residual interests during the
fiscal six months ended March 31, 2008 were $208,418,571 and 3.80%,
respectively.

                                                                              55

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset
management ("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, 2008, the Fund recognized expenses of
approximately $23,400 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such
firm and he and his law firm provide legal services as legal counsel to the
Fund.

    Under separate Legal Services, Accounting Services, and Chief Compliance
Officer (CCO) Employment agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Fund. The costs of
these services are allocated to each fund. For the six months ended March 31,
2008, the Fund recognized expenses of approximately $68,900 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, as well as the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Professional Fees" on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Accounting and Administrative Expenses" on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the six months ended
March 31, 2008, the Fund recognized expenses of approximately $138,000
representing transfer agency fees paid to VKIS and its affiliates. Transfer
agency fees are determined through negotiations with the Fund's Board of
Trustees.

    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 also
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 approximately $187,600
are included in "Other" assets on the Statement of Assets and Liabilities at
March 31, 2008. 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.

    For the six months ended March 31, 2008, Van Kampen, as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $230,300 and contingent deferred sales charge (CDSC) on redeemed
shares of approximately $144,700. Sales charges do not represent expenses of the
Fund.

4. REDEMPTION FEE

The Fund will assess a 2% redemption fee on the proceeds of Fund shares that are
redeemed (either by sale or exchange) within 30 days of purchase. The redemption
fee is paid directly to the Fund and allocated on pro rata basis to each class
of shares. For the six months ended March 31, 2008, the Fund received redemption
fees of approximately $25,800, which are reported as part of "Cost of Shares
Repurchased" on the Statements of Changes in Net Assets. The per share impact
from redemption fees paid to the Fund was less than $0.01.

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $156,952,387 and 254,322,602,
respectively.

6. 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 may use derivative instruments for a variety of reasons, such
as to attempt to protect the Fund against possible changes in the market value
of its portfolio, to manage the portfolio's effective yield, maturity and
duration, or generate potential gain. All of the Fund's portfolio holdings,

                                                                              57


VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

including derivative instruments, are marked to market each day with the change
in value reflected in unrealized appreciation/depreciation. Upon disposition, a
realized gain or loss is recognized accordingly, except when taking delivery of
a security underlying a futures contract. In this instance, the recognition of
gain or loss is postponed until the disposal of the security underlying the
futures contract. Risks may arise as a result of the potential inability of the
counterparties to meet the terms of their contracts.

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

A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in exchange traded futures contracts on U.S. Treasury
Securities and typically closes the contract prior to the delivery date. These
contracts are generally used to manage the Fund's effective maturity and
duration. Upon entering into futures contracts, the Fund maintains an amount of
cash or liquid securities with a value equal to a percentage of the contract
amount with either a futures commission merchant pursuant to rules and
regulations promulgated under the 1940 Act, as amended, or with its custodian in
an account in the broker's name. This amount is known as initial margin. During
the period the futures contract is open, payments are received from or made to
the broker based upon changes in the value of the contract (the variation
margin).

    Transactions in future contracts for six months ended March 31, 2008, are as
follows:

<Table>
<Caption>
                                                              CONTRACTS
                                                           
Outstanding at September 30, 2007...........................      810
Futures Opened..............................................      498
Futures Closed..............................................   (1,308)
                                                               ------
Outstanding at March 31, 2008...............................      -0-
                                                               ======
</Table>

B. INVERSE FLOATING RATE INVESTMENTS The Fund may invest a portion of its assets
in inverse floating rate instruments, either through outright purchases of
inverse floating rate securities or through the transfer of bonds to a dealer
trust in exchange for cash and residual interests in the dealer trust. These
investments are typically used by the Fund in seeking to enhance the yield of
the portfolio. These instruments typically involve greater risks than a fixed
rate municipal bond. In particular, these instruments are acquired through
leverage or may have leverage embedded in them and therefore involve many of the
risks associated with leverage. Leverage is a speculative technique that may
expose the Fund to greater risk and increased costs. Leverage may cause the
Fund's net asset value to be more volatile than if it had not been leveraged
because leverage tends to magnify the effect of any increases or decreases in
the value of the Fund's portfolio securities. The use of leverage may also cause
the Fund to liquidate portfolio positions when it may not be advantageous to do
so in order to satisfy its obligations with respect to inverse floating rate
instruments.

7. DISTRIBUTION AND SERVICE PLANS

Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"),
an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant
to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively,
the "Plans") for Class A Shares,

 58


VAN KAMPEN STRATEGIC MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

Class B Shares and Class C Shares to compensate the Distributor for the sale,
distribution, shareholder servicing and maintenance of shareholder accounts for
these shares. Under the Plans, the Fund will incur annual fees of up to .25% of
Class A average daily net assets and up to 1.00% each of Class B and Class C
average daily net assets. These fees are accrued daily and paid to the
Distributor monthly.

    The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed receivable") was approximately $1,623,000 and $200,500
for Class B and Class C Shares, respectively. These amounts may be recovered
from future payments under the distribution plan or CDSC. To the extent the
unreimbursed receivable has been fully recovered, the distribution fee is
reduced.

8. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote

9. ACCOUNTING PRONOUNCEMENTS

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. As of March 31, 2008, the Adviser does not believe the adoption of
SFAS 157 will impact the amounts reported in the financial statements, however,
additional disclosures will be required about the inputs used to develop the
measurements of fair value and the effect of certain measurements reported on
the Statement of Operations for a fiscal period.

                                                                              59

The returns shown in this report do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Performance of share classes will vary due to differences in sales charges and
expenses. Average annual total return with sales charges includes payment of the
maximum sales charge of 4.75 percent for Class A shares, a contingent deferred
sales charge of 4.00 percent for Class B shares (in years one and two and
declining to zero after year five), a contingent deferred sales charge of 1.00
percent for Class C shares in year one and combined Rule 12b-1 fees and service
fees of up to 0.25 percent for Class A shares and up to 1.00 percent for Class B
and C shares. The since inception and 10-year returns for Class B shares reflect
the conversion of Class B shares into Class A shares eight years after purchase.
The since inception returns for Class C shares reflect the conversion of Class C
shares into Class A shares ten years after purchase. Class I shares are
available for purchase exclusively by investors through (i) tax-exempt
retirement plans with assets of at least $1 million (including 401(k) plans, 457
plans, employer-sponsored 403(b) plans, profit sharing and money purchase plans,
defined benefit plans and non-qualified deferred compensation plans), (ii)
fee-based investment programs with assets of at least $1 million, (iii)
qualified state tuition plan (529 plan) accounts, (iv) institutional clients
with assets of at least $1 million and (v) certain Van Kampen investment
companies. Class I shares are offered without any sales charges on purchases or
sales and do not include combined Rule 12b-1 fees and service fees. Figures
shown above assume reinvestment of all dividends and capital gains.

SEC yield is a calculation for determining the amount of portfolio income,
excluding non-income items as prescribed by the SEC. Yields are subject to
change.

The Lehman Brothers Municipal Bond Index is generally representative of
investment-grade, tax-exempt bonds. The Lehman Brothers California Insured
Municipal Bond Index is comprised of insured CA municipal bond issues. The
indexes do not include any expenses, fees or sales charges, which would lower
performance. The indexes are unmanaged and should not be considered investments.

Fund Report

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2008

MARKET CONDITIONS

The financial markets experienced significant volatility throughout the
six-month reporting period as many large banks and financial firms began writing
down mortgage-related losses, and liquidity and credit availability became even
more restricted. At the same time, the pace of economic growth began to slow,
with gross domestic product (GDP) growth measuring an anemic 0.6 percent for the
fourth quarter of 2007. As weaker economic data was released in the first
quarter of 2008, fears of recession grew and consumer confidence waned,
prompting investors to continue to seek the relative safety of high-quality
Treasury securities over other sectors of the fixed income market.

The municipal bond market faced additional headwinds as various monoline bond
insurers experienced credit quality downgrades and the auction rate and variable
rate markets deteriorated. As a result, the municipal market underperformed
Treasuries for the overall period, with municipal bond prices reaching
historically attractive levels relative to Treasury bonds in the first quarter
of 2008. While yields on short-dated municipal securities declined, yields on
intermediate- and long-dated securities rose, leading to the steepest yield
curve in the past four years as the spread between one-year and 30-year
maturities reached 343 basis points. After a record year for new municipal bond
issuance in 2007, the amount of new issues coming to market in the first quarter
of 2008 declined by roughly 25 percent due in large part to a substantial drop
in refunding issuance. Insured bond issuance declined dramatically in the first
quarter, from approximately 50 percent to 25 percent of total new-issue supply.
Although issuance by the State of California declined as well, it remained the
largest issuer of municipal bonds in the country.

The Federal Reserve (the "Fed") took various steps to ease the liquidity crisis
and boost the economy during the period. Not only did the Fed reduce the target
federal funds rate from 4.75 percent to 2.25 percent by the end of the period,
but in an unprecedented move, it granted primary brokerage firms access to its
discount window and loosened its collateral requirements, extending loans of
Treasury securities in exchange for lower quality, less liquid securities.
Finally, in the biggest headline event, the Fed arranged and supported JP Morgan
Chase's purchase of Bear Stearns, which was viewed by many as necessary to avoid
serious market repercussions had the firm failed.

PERFORMANCE ANALYSIS

All share classes of Van Kampen California Insured Tax Free Fund underperformed
the Lehman Brothers California Insured Municipal Bond Index and the Lehman
Brothers Municipal Bond Index for the six months ended March 31, 2008, assuming
no deduction of applicable sales charges.

The performance for the four share classes varies because each has different
expenses. The Fund's total return figures assume the reinvestment of all
distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and
index definitions.

Although the municipal bond market rebounded in the last month of the reporting
period and outperformed Treasuries, it was a difficult period overall,
particularly for the insured sector as the credit downgrades of various monoline
insurers put considerable pressure on prices. Rising rates in the intermediate
and long maturity portions of the yield curve also hurt the performance of these
more interest-rate sensitive securities. Furthermore, the State of California
has been particularly hard hit by the ongoing deterioration in the residential
housing market. As a result, spreads in the housing sector widened dramatically
during the period, negatively impacting its performance. Spreads in the tobacco
and health care sectors also widened considerably. As a result, the Fund's
holdings in these three sectors were the primary detractors from performance.
These positions were held mainly in the form of inverse floating-rate
securities,* which are uninsured but still investment grade issues, and did
serve to enhance the Fund's income and diversification during the period.

We continued to favor longer maturity bonds in an effort to capture higher
yields, which resulted in a longer duration (a measure of interest-rate
sensitivity) for the portfolio. To reduce that duration somewhat, we used a
Treasury futures hedge for much of the period. Unfortunately, rising rates on
the long end of the curve coupled with the Treasury market rally caused this
positioning to detract from performance. We did, however, unwind the hedge,
investing the proceeds in auction rate securities for their favorable yields.

Holdings in other sectors, however, contributed positively to performance. In
particular, transportation (airport), industrial development revenue and
pollution control revenue bonds were additive to returns.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the Fund in
the future.

*An inverse floating-rate security, or "inverse floater", is a variable rate
security whose coupon rate changes in the opposite direction from the change in
the reference rate used to calculate the coupon rate.

Expense Example

As a shareholder of the Fund, you incur two types of costs : (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and C Shares;
and redemption fees; and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees; and other Fund expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 10/1/07 - 3/31/08.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing cost of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds. Please note that the expenses shown in the table are meant
to highlight your ongoing costs only and do not reflect any transactional costs,
such as sales charges (loads) or contingent deferred sales charges or redemption
fees. Therefore, the second line of the table is useful in comparing ongoing
costs only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
costs would have been higher.

VAN KAMPEN CALIFORNIA INSURED TAX FREE FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen California Insured Tax Free Fund (the "Fund") is organized as a
series of the Van Kampen Tax Free Trust, a Delaware statutory 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 only California investors with a high level
of current income exempt from federal and California income taxes, with
liquidity and safety of principal, primarily through investment in a diversified
portfolio of insured California municipal securities. The Fund commenced
investment operations on December 13, 1985. The Fund offers Class A Shares,
Class B Shares, Class C Shares and Class I Shares. Each class of shares differs
by its initial sales load, contingent deferred sales charges, the allocation of
class specific expenses and voting rights on matters affecting a single class.

    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 U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the last reported 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. Futures contracts are valued at the settlement price established each
day on the exchange on which they are traded. Interest rate swaps are valued
using market quotations obtained from brokers. 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
segregate assets with the custodian 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, 2008, the Fund had $1,227,900 of when-issued and
delayed delivery purchase commitments.

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
incremental transfer agency costs which are unique to each class of shares.

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M 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 adopted the provisions of the Financial Accounting Standards Board ("FASB")
Interpretation No. 48 ("FIN 48") Accounting for Uncertainty in Income Taxes on
March 31, 2008. FIN 48 sets forth a minimum threshold for financial statement
recognition of the benefit of a tax position taken or expected to be taken in a
tax return. The implementation of FIN 48 did not result in any unrecognized tax
benefits in the accompanying financial statements. If applicable, the Fund
recognizes interest accrued related to unrecognized tax benefits in "Interest
Expense" and penalties in "Other" expenses on the Statement of Operations. The
Fund files tax returns with the U.S. Internal Revenue Service and various
states. Generally, each of the tax years in the four year period ended September
30, 2007, remains subject to examination by taxing authorities.

    At March 31, 2008, the cost and related gross unrealized appreciation and
depreciation were as follows:

<Table>

</Table>

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 at least annually. Distributions from net realized gains for book
purposes may include short-term capital gains and a portion of futures gains,
which are included in ordinary income for tax purposes.

    The tax character of distributions paid during the year ended September 30,
2007 was as follows:

<Table>
                                                           
Distributions paid from:
  Ordinary income...........................................  $   70,484
  Tax exempt income.........................................   8,771,483
  Long-term capital gain....................................     866,832
                                                              ----------
                                                              $9,708,799
                                                              ==========
</Table>

    As of September 30, 2007, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $  1,112
Undistributed tax-exempt income.............................   853,475
Undistributed long-term capital gain........................       -0-
</Table>

    Net realized gains or losses may differ for financial reporting and tax
purposes primarily as a result of gains or losses recognized on securities for
tax purposes but not for book.

F. FLOATING RATE NOTE OBLIGATIONS RELATED TO SECURITIES HELD The Fund enters
into transactions in which it transfers to dealer trusts fixed rate bonds in
exchange for cash and

                                                                              25


VAN KAMPEN CALIFORNIA INSURED TAX FREE FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

residual interest in the dealer trusts' assets and cash flows, which are in the
form of inverse floating rate investments. The dealer trusts fund the purchases
of the fixed rate bonds by issuing floating rate notes to third parties and
allowing the Fund to retain residual interests in the bonds. The Fund enters
into shortfall agreements with the dealer trusts, which commit the Fund to pay
the dealer trusts, in certain circumstances, the difference between the
liquidation value of the fixed rate bonds held by the dealer trusts and the
liquidation value of the floating rate notes held by third parties, as well as
any shortfalls in interest cash flows. The residual interests held by the Fund
(inverse floating rate investments) include the right of the Fund (1) to cause
the holders of the floating rate notes to tender their notes at par at the next
interest rate reset date, and (2) to transfer the municipal bond from the dealer
trusts to the Fund, thereby collapsing the dealer trusts. The Fund accounts for
the transfer of bonds to the dealer trusts as secured borrowings, with the
securities transferred remaining in the Fund's investments assets, and the
related floating rate notes reflected as Fund liabilities under the caption
"Floating Rate Note Obligations" on the Statement of Assets and Liabilities. The
Fund records the interest income from the fixed rate bonds under the caption
"Interest" and records the expenses related to floating rate note obligations
and any administrative expenses of the dealer trusts under the caption "Interest
and Residual Trust Expenses" in the Fund's Statement of Operations. The notes
issued by the dealer trust have interest rates that reset weekly and the
floating rate note holders have the option to tender their notes to the dealer
trusts for redemption at par at each reset date. At March 31, 2008, Fund
investments with a value of $42,960,030 are held by the dealer trusts and serve
as collateral for the $32,750,000 in floating rate notes outstanding at that
date. Contractual maturities of the floating rate notes and interest rates in
effect at March 31, 2008 are presented on the Portfolio of Investments. The
average floating rate notes outstanding and average annual interest and fee rate
related to residual interests during the six months ended March 31, 2008 were
$36,164,286 and 3.71%, respectively.

G. 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

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset
Management (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

Next $250 million...........................................    0.425%
Over $500 million...........................................    0.400%
</Table>

    For the six months ended March 31, 2008, the Fund recognized expenses of
approximately $12,000 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such
firm and he and his law firm provide legal services as legal counsel to the
Fund.

    Under separate Legal services, Accounting Services and Chief Compliance
Officer (CCO) Employment agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Fund. The costs of
these services are allocated to each fund. For the six months ended March 31,
2008, the Fund recognized expenses of approximately $26,600 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, as well as the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Professional Fees" on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Accounting and Administrative Expenses" on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the six months ended
March 31, 2008, the Fund recognized expenses of approximately $21,800
representing transfer agency fees paid to VKIS and its affiliates. The transfer
agency fees are determined through negotiations with the Fund's Board of
Trustees.

    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 also
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 $140,690 are included in
"Other" assets on the Statement of Assets and Liabilities at March 31, 2008.
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.

    For the six months ended March 31, 2008, Van Kampen, as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $29,800 and

                                                                              27

4. REDEMPTION FEE

The Fund will assess a 2% redemption fee on the proceeds of Fund shares that are
redeemed (either by sale or exchange) within seven days of purchase. The
redemption fee is paid directly to the Fund and allocated on a pro rata basis to
each class of shares. For the six months ended March 31, 2008, the Fund did not
receive any redemption fees.

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $47,381,054 and $28,344,743,
respectively.

6. 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 may use derivative instruments for a variety of reasons, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage

 28


VAN KAMPEN CALIFORNIA INSURED TAX FREE FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

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.
Upon disposition, a realized gain or loss is recognized accordingly, except when
taking delivery of a security underlying a futures contract. In these instances,
the recognition of gain or loss is postponed until the disposal of the security
underlying the futures contract. Risks may arise as a result of the potential
inability of the counterparties to meet the terms of their contracts. Summarized
below are the specific types of derivative financial instruments used by the
Fund.

A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in futures on U.S. Treasury Notes and typically closes
the contract prior to the delivery date. Upon entering into futures contracts,
the Fund maintains an amount of cash or liquid securities with a value equal to
a percentage of the contract amount with either a futures commission merchant
pursuant to rules and regulations promulgated under the 1940 Act, as amended, or
with its custodian in an account in the broker's name. This amount is known as
initial margin. During the period the futures contract is open, payments are
received from or made to the broker based upon changes in the value of the
contract (the variation margin). The risk of loss associated with a futures
contract is in excess of the variation margin reflected on the Statement of
Assets and Liabilities.

    Transactions in futures contracts for the six months ended March 31, 2008,
were as follows:

<Table>

                                                              CONTRACTS
                                                           
Outstanding at September 30, 2007...........................      73
Futures Opened..............................................     206
Futures Closed..............................................    (279)
                                                                ----

                                                                ====
</Table>

B. INVERSE FLOATING RATE INVESTMENTS The Fund may invest a portion of its assets
in inverse floating rate instruments, either through outright purchases of
inverse floating rate securities or through the transfer of bonds to a dealer
trust in exchange for cash and residual interests in the dealer trust. These
investments are typically used by the Fund in seeking to enhance the yield of
the portfolio. These instruments typically involve greater risks than a fixed
rate municipal bond. In particular, these instruments are acquired through
leverage or may have leverage embedded in them and therefore involve many of the
risks associated with leverage. Leverage is a speculative technique that may
expose the Fund to greater risk and increased costs. Leverage may cause the
Fund's net asset value to be more volatile than if it had not been leveraged
because leverage tends to magnify the effect of any increases or decreases in
the value of the Fund's portfolio securities. The use of leverage may also cause
the Fund to liquidate portfolio positions when it may not be advantageous to do
so in order to satisfy its obligations with respect to inverse floating rate
instruments.

C. INTEREST RATE SWAPS The Fund may enter into forward interest rate swap
transactions intended to help the Fund manage its overall interest rate
sensitivity, either shorter or longer, generally to more closely align the
Fund's interest rate sensitivity with that of the broader

                                                                              29


VAN KAMPEN CALIFORNIA INSURED TAX FREE FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

municipal market. Forward interest rate swap transactions involve the Fund's
agreement with a counterparty to pay, in the future, a fixed or variable rate
payment in exchange for the counterparty paying the Fund a variable or fixed
rate payment, the accruals for which would begin at a specified date in the
future (the "effective date"). The amount of the payment obligation is based on
the notional amount of the forward swap contract and the termination date of the
swap (which is akin to a bond's maturity). The value of the Fund's swap
commitment would increase or decrease based primarily on the extent to which
long-term interest rates for bonds having a maturity of the swap's termination
date increases or decreases. The Fund may terminate a swap contract prior to the
effective date, at which point a realized gain or loss is recognized. When a
forward swap is terminated, it ordinarily does not involve the delivery of
securities or other underlying assets or principal, but rather is settled in
cash on a net basis. The Fund intends, but is not obligated, to terminate its
forward swaps before the effective date. Accordingly, the risk of loss with
respect to the swap counterparty on such transactions is limited to the credit
risk associated with a counterparty failing to honor its commitment to pay any
realized gain to the Fund upon termination. To reduce such credit risk, all
counterparties are required to pledge collateral daily (based on the daily
valuation of each swap) on behalf of the Fund with a value approximately equal
to the amount of any unrealized gain. Reciprocally, when the Fund has an
unrealized loss on a swap contract, the Fund has instructed the custodian to
pledge cash or liquid securities as collateral with a value approximately equal
to the amount of the unrealized loss. Collateral pledges are monitored and
subsequently adjusted if and when the swap valuations fluctuate. Restricted cash
for segregating purposes, if any, is shown on the Statement of Assets and
Liabilities.

7. DISTRIBUTION AND SERVICE PLANS

Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"),
an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant
to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively,
the "Plans") for Class A Shares, Class B Shares and Class C Shares to compensate
the Distributor for the sale, distribution, shareholder servicing and
maintenance of shareholder accounts for these shares. Under the Plans, the Fund
will incur annual fees of up to .25% of Class A average daily net assets and up
to 1.00% each of Class B and Class C average daily net assets. These fees are
accrued daily and paid to the Distributor monthly.

    The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed receivable") was approximately $0 for Class B and
Class C Shares. These amounts may be recovered from future payments under the
distribution plan or CDSC. To the extent the unreimbursed receivable has been
fully recovered, the distribution fee is reduced.

8. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

9. ACCOUNTING PRONOUNCEMENT

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after

 30


VAN KAMPEN CALIFORNIA INSURED TAX FREE FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

November 15, 2007. SFAS 157 defines fair value, establishes a framework for
measuring fair value and expands disclosures about fair value measurements. As
of March 31, 2008, the Adviser does not believe the adoption of SFAS 157 will
impact the amounts reported in the financial statements, however, additional
disclosures will be required about the inputs used to develop the measurements
of fair value and the effect of certain measurements reported on the Statement
of Operations for a fiscal period.

                                                                              31

PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF
FUTURE RESULTS, AND CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN THE FIGURES
SHOWN. FOR THE MOST RECENT MONTH-END PERFORMANCE FIGURES, PLEASE VISIT
VANKAMPEN.COM OR SPEAK WITH YOUR FINANCIAL ADVISOR. INVESTMENT RETURNS AND
PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES, WHEN REDEEMED, MAY BE WORTH MORE
OR LESS THAN THEIR ORIGINAL COST.

The returns shown in this report do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Performance of share classes will vary due to differences in sales charges and
expenses. Average annual total return with sales charges includes payment of the
maximum sales charge of 4.75 percent for Class A shares, a contingent deferred
sales charge of 4.00 percent for Class B shares (in year one and declining to
zero after year six), a contingent deferred sales charge of 1.00 percent for
Class C shares in year one and combined Rule 12b-1 fees and service fees of up
to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C
shares. The since inception and 10-year returns for Class B shares reflect the
conversion of Class B shares into Class A shares eight years after purchase. The
since inception returns for Class C shares reflect the conversion of Class C
shares into Class A shares ten years after purchase. Class I shares are
available for purchase exclusively by investors through (i) tax-exempt
retirement plans with assets of at least $1 million (including 401(k) plans, 457
plans, employer-sponsored 403(b) plans, profit sharing and money purchase plans,
defined benefit plans and non-qualified deferred compensation plans), (ii)
fee-based investment programs with assets of at least $1 million, (iii)
qualified state tuition plan (529 plan) accounts, (iv) institutional clients
with assets of at least $1 million and (v) certain Van Kampen investment
companies. Class I shares are offered without any sales charges on purchases or
sales and do not include combined rule 12b-1 fees and service fees. Figures
shown above assume reinvestment of all dividends and capital gains. Periods of
less than a year are not annualized. SEC yield is a calculation for determining
the amount of portfolio income, excluding non-income items as prescribed by the
SEC. Yields are subject to change.

The Lehman Brothers Municipal Bond Index is generally representative of
investment-grade, tax-exempt bonds. The index does not include any expenses,
fees or sales charges, which would lower performance. The index is unmanaged and
should not be considered an investment. It is not possible to invest directly in
an index.

Fund Report

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2008

MARKET CONDITIONS

The financial markets experienced significant volatility throughout the
six-month reporting period as many large banks and financial firms began writing
down mortgage-related losses, and liquidity and credit availability became even
more restricted. At the same time, the pace of economic growth began to slow,
with gross domestic product (GDP) growth measuring an anemic 0.6 percent for the
fourth quarter of 2007. As weaker economic data was released in the first
quarter of 2008, fears of recession grew and consumer confidence waned,
prompting investors to continue to seek out the relative safety of high quality
Treasury securities over other sectors of the fixed income market.

The municipal bond market faced additional headwinds as various monoline bond
insurers experienced credit quality downgrades and the auction rate and variable
rate markets deteriorated. As a result, the municipal market underperformed
Treasuries for the overall period, with municipal bond prices reaching the
cheapest levels ever relative to Treasury bonds in the first quarter of 2008.
While yields on short-dated municipal securities declined, yields on
intermediate- and long-dated securities rose, leading to the steepest yield
curve in the past four years as the spread between one-year and 30-year
maturities reached 343 basis points. After a record year for new municipal bond
issuance in 2007, the amount of new issues coming to market in the first quarter
of 2008 declined by roughly 25 percent due in large part to a substantial drop
in refunding issuance.

The Federal Reserve (the "Fed") took various steps to ease the liquidity crisis
and boost the economy during the period. Not only did the Fed reduce the target
federal funds rate from 4.75 percent to 2.25 percent by the end of the period,
but in an unprecedented move, it granted primary brokerage firms access to its
discount window and loosened its collateral requirements, extending loans of
Treasury securities in exchange for lower quality, less liquid securities.
Finally, in the biggest headline event, the Fed arranged and supported JP Morgan
Chase's purchase of Bear Stearns, which was viewed by many as necessary to avoid
serious market repercussions had the firm failed.

The performance for the four share classes varies because each has different
expenses. The Fund's total return figures assume the reinvestment of all
distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and
index definition.

Although the municipal market rebounded in the last month of the reporting
period and outperformed Treasuries, it was an extremely difficult period
overall, particularly for higher yielding, lower rated bonds as the
flight-to-quality put considerable pressure on prices. The Fund maintained an
allocation to double-B and non-rated bonds throughout the reporting period
whereas the benchmark Lehman Brother Municipal Bond Index contains only
investment grade issues. As such, the Fund's overweight to lower rated, higher
yielding securities was a primary contributor to its relative underperformance.

The Fund's yield curve positioning also hindered performance as it was
overweighted on the long end of the curve, which underperformed the shorter end
of the curve for the period. The negative impact was amplified by holdings in
longer maturity inverse floating-rate securities,* which are highly sensitive to
interest rate changes. However, these securities did serve to enhance the Fund's
income and diversification during the period. Additionally, the emphasis on the
long end of the curve led to a longer duration (a measure of interest-rate
sensitivity) for the Fund, which we lowered somewhat through the use of a
Treasury futures hedge. However, the Fund still maintained a slightly longer
duration, which detracted from performance as rates on the intermediate and long
end of the curve rose. At the same time, the Treasury market rally hurt the
performance of the hedge.

Conversely, an overweight to pre-refunded bonds was additive to performance.
These are high quality, shorter maturity issues which benefited as the short end
of the curve outpaced the long end during the period. The Fund's overweight to
higher yielding municipal auction rate securities, which have low durations (a
measure of interest-rate sensitivity) was also beneficial to performance.

*An inverse floating-rate security, or "inverse floater", is a variable rate
security whose coupon rate changes in the opposite direction from the change in
the reference rate used to calculate the coupon rate.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the Fund in
the future.

       Each Van Kampen fund provides a complete schedule of portfolio holdings
       in its semiannual and annual reports within 60 days of the end of the

       mailings to the same address. The Fund delivers a single copy of certain
       shareholder documents to investors who share an address, even if the
       accounts are registered under different names. The Fund's prospectuses
       and shareholder reports (including annual privacy notices) will be
       delivered to you in this manner indefinitely unless you instruct us
       otherwise. You can request multiple copies of these documents by either
       calling (800) 341-2911 or writing to Van Kampen Investor Services at P.O.
       Box 219286, Kansas City, MO 64121-9286. Once Investor Services has
       received your instructions, we will begin sending individual copies for
       each account within 30 days.

PROXY VOTING POLICY AND PROCEDURES AND PROXY VOTING RECORD

       You may obtain a copy of the Fund's Proxy Voting Policy and Procedures
       without charge, upon request, by calling toll free (800) 847-2424 or by
       visiting our Web site at www.vankampen.com. It is also available on the
       Securities and Exchange Commission's Web site at http://www.sec.gov.

       You may obtain information regarding how the Fund voted proxies relating
       to portfolio securities during the most recent twelve-month period ended
       June 30 without charge by visiting our Web site at www.vankampen.com.
       This information is also available on the Securities and Exchange
       Commission's Web site at http://www.sec.gov.

                                                                               7


Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and Class C
Shares; and redemption fees; and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees; and other Fund expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 10/1/07 - 3/31/08.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing cost of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or contingent deferred sales charges or redemption fees.
Therefore, the second line of the table is useful in comparing ongoing costs
only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
costs would have been higher.

VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Municipal Income Fund (the "Fund") is organized as a series of the
Van Kampen Tax Free Trust, a Delaware statutory 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 a high level of current income exempt from federal income tax,
consistent with preservation of capital. The Fund commenced investment
operations on August 1, 1990. The Fund offers Class A Shares, Class B Shares,
Class C Shares and Class I Shares. Each class of shares differs by its initial
sales load, contingent deferred sales charges, the allocation of class-specific
expenses and voting rights on the matters affecting a single class.

    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 U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION 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.
Futures contracts are valued at the settlement price established each day on the
exchange on which they are traded. 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.
Legal expenditures that are expected to result in the restructuring of or a plan
of reorganization for an investment are recorded as realized losses. 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 segregate
assets with the custodian 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, 2008, the Fund had $7,118,129 of when-issued and delayed
delivery purchase commitments.

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
incremental transfer agency costs which are unique to each class of shares.

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

provision for federal income taxes is required. The Fund adopted the provisions
of the Financial Accounting Standards Board ("FASB") Interpretation No. 48 ("FIN
48") Accounting for Uncertainty in Income Taxes on March 31, 2008. FIN 48 sets
forth a minimum threshold for financial statement recognition of the benefit of
a tax position taken or expected to be taken in a tax return. The implementation
of FIN 48 did not result in any unrecognized tax benefits in the accompanying
financial statements. If applicable, the Fund recognizes interest accrued
related to unrecognized tax benefits in "Interest Expense" and penalties in
"Other" expenses on the Statement of Operations. The Fund files tax returns with
the U.S. Internal Revenue Service, New York and various states. Generally, each
of the tax years in the four year period ended September 30, 2007, remains
subject to examination by taxing authorities

    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, 2007, the Fund had an accumulated capital loss
carryforward for tax purposes of $32,062,970, which will expire according to the
following schedule.

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 at least annually. Distributions from net realized gains for book
purposes may include short-term capital gains and gains on futures transactions.
All short-term capital gains and a portion of futures gains are included in
ordinary income for tax purposes.

    The tax character of distributions paid during the year ended September 30,
2007 were as follows:

    As of September 30, 2007, the components of distributable earnings on a tax
basis were as follows:

<Table>
                                                           
Undistributed ordinary income...............................  $    8,822
Undistributed tax-exempt income.............................   5,695,373
</Table>

F. CREDITS EARNED ON CASH BALANCES During the six months ended March 31, 2008,
the Fund's custody fee was reduced by $14,239 as a result of credits earned on
cash balances.

G. FLOATING RATE NOTE OBLIGATIONS RELATED TO SECURITIES HELD The Fund enters
into transactions in which it transfers to dealer trusts fixed rate bonds in
exchange for cash and residual interest in the dealer trusts' assets and cash
flows, which are in the form of inverse floating rate investments. The dealer
trusts fund the purchases of the fixed rate bonds by issuing floating rate notes
to third parties and allowing the Fund to retain residual interests in the
bonds. The Fund enters into shortfall agreements with the dealer trusts, which
commit the Fund to pay the dealer trusts, in certain circumstances, the
difference between the liquidation value of the fixed rate bonds held by the
dealer trusts and the liquidation value of the floating rate notes held by third
parties, as well as any shortfalls in interest cash flows. The residual
interests held by the Fund (inverse floating rate investments) include the right
of the Fund (1) to cause the holders of the floating rate notes to tender their
notes at par at the next interest rate reset date, and (2) to transfer the
municipal bond from the dealer trusts to the Fund, thereby collapsing the dealer
trusts. The Fund accounts for the transfer of bonds to the dealer trusts as
secured borrowings, with the securities transferred remaining in the Fund's
investments assets, and the related floating rate notes reflected as Fund
liabilities under the caption "Floating Rate Note Obligations" on the Statement
of Assets and Liabilities. The Fund records the interest income from the fixed
rate bonds under the caption "Interest" and records the expenses related to
floating rate note obligations and any administrative expenses of the dealer
trusts under the caption "Interest and Residual Trust Expenses" in the Fund's
Statement of Operations. The notes issued by the dealer trust have interest
rates that reset weekly and the floating rate note holders have the option to
tender their notes to the dealer trusts for redemption at par at each reset
date. At March 31, 2008, Fund investments with a value of $178,322,063 are held
by the dealer trusts and serve as collateral for the $108,890,000 in floating
rate notes outstanding at that date. Contractual maturities of the floating rate
notes and interest rates in effect at March 31, 2008 are presented on the
Portfolio of Investments. The average floating rate notes outstanding and
average annual interest and fee rate related to residual interests during the
six months ended March 31, 2008 were $114,345,000 and 3.57%, respectively.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset
Management (the "Adviser") will provide investment advice and facilities to the
Fund for an annual fee payable monthly as follows:

    For the six months ended March 31, 2008, the Fund recognized expenses of
approximately $9,900 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of which a trustee of the Fund is a partner of such
firm and he and his law firm provide legal services as legal counsel to the
Fund.

    Under separate Legal Services, Accounting Services and Chief Compliance
Officer (CCO) Employment Agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Fund. The costs of
these services are allocated to each fund. For the six months ended March 31,
2008, the Fund recognized expenses of approximately $42,400 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, as well as the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Professional Fees" on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Accounting and Administrative Expenses" on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the six months ended
March 31, 2008, the Fund recognized expenses of approximately $86,400
representing transfer agency fees paid to VKIS and its affiliates. The transfer
agency fees are determined through negotiations with the Fund's Board of
Trustees.

    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 also
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 $195,610 are included in
"Other" assets on the Statements of Assets and Liabilities at March 31, 2008.
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.

    For the six months ended March 31, 2008, Van Kampen as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $55,000 and contingent deferred sales charge (CDSC) on redeemed
shares of approximately $23,000. Sales charges do not represent expenses of the
Fund.

    At March 31, 2008, Morgan Stanley Investment Management, Inc., an affiliate
of the Adviser, owned 710 shares of Class I Shares.

                                                                              39

4. REDEMPTION FEE

The Fund will assess a 2% redemption fee on the proceeds of Fund shares that are
redeemed (either by sale or exchange) within seven days of purchase. The
redemption fee is paid directly to the Fund and allocated on a pro rata basis to
each class of shares. For the six months ended March 31, 2008, the Fund received
redemption fees of approximately $3,700, which are reported as part of "Cost of
Shares Repurchased" on the Statement of Changes in Net Assets. The per share
impact from redemption fees paid to the Fund was less than $0.01.

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $176,415,575 and $168,570,186,
respectively.

6. 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 may use derivative instruments for a variety of reasons, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio, to manage the portfolio's effective yield, maturity and duration, or
generate potential gain. All of the Fund's

 40


VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

portfolio holdings, including derivative instruments, are marked to market each
day with the change in value reflected in unrealized appreciation/depreciation.
Upon disposition, a realized gain or loss is recognized accordingly, except when
taking delivery of a security underlying a futures contract. In these instances,
the recognition of gain or loss is postponed until the disposal of the security
underlying the futures contract. Risks may arise as a result of the potential
inability of the counter parties to meet the terms of their contracts.

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

A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in exchange traded futures on U.S. Treasury Notes and
typically closes the contract prior to delivery date. Upon entering into futures
contracts, the Fund maintains an amount of cash or liquid securities with a
value equal to a percentage of the contract amount with either a futures
commission merchant pursuant to rules and regulations promulgated under the 1940
Act, as amended, or with its custodian in an account in the broker's name. This
amount is known as initial margin. During the period the futures contract is
open, payments are received from or made to the broker based upon changes in the
value of the contract (the variation margin). The risk of loss associated with a
futures contract is in excess of the variation margin reflected on the Statement
of Assets and Liabilities.

    Transactions in futures contracts for the six months ended March 31, 2008,
were as follows:

</Table>

B. INVERSE FLOATING RATE INVESTMENTS The Fund may invest a portion of its assets
in inverse floating rate instruments, either through outright purchases of
inverse floating rate securities or through the transfer of bonds to a dealer
trust in exchange for cash and residual interests in the dealer trust. These
investments are typically used by the Fund in seeking to enhance the yield of
the portfolio. These instruments typically involve greater risks than a fixed
rate municipal bond. In particular, these instruments are acquired through
leverage or may have leverage embedded in them and therefore involve many of the
risks associated with leverage. Leverage is a speculative technique that my
expose the Fund to greater risk and increased costs. Leverage may cause the
Fund's net asset value to be more volatile than if it had not been leveraged
because leverage tends to magnify the effect of any increases or decreases in
the value of the Fund's portfolio securities. The use of leverage may also cause
the Fund to liquidate portfolio positions when it may not be advantageous to do
so in order to satisfy its obligations with respect to inverse floating rate
instruments.

7. DISTRIBUTION AND SERVICE PLANS

Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"),
an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant
to Rule 12b-1 under the

                                                                              41


VAN KAMPEN MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

1940 Act, as amended, and a service plan (collectively, the "Plans") for Class A
Shares, Class B Shares and Class C Shares to compensate the Distributor for the
sale, distribution, shareholder servicing and maintenance of shareholder
accounts for these shares. Under the Plans, the Fund will incur annual fees of
up to .25% of Class A average daily net assets and up to 1.00% each of Class B
and Class C average daily net assets. These fees are accrued daily and paid to
the Distributor monthly.

    The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed receivable") was approximately $2,486,900 and $233,200
for Class B and Class C Shares, respectively. These amounts may be recovered
from future payments under the distribution plan or CDSC. To the extent the
unreimbursed receivable has been fully recovered, the distribution fee is
reduced.

8. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

9. ACCOUNTING PRONOUNCEMENT

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. As of March 31, 2008, the Adviser does not believe the adoption of
SFAS 157 will impact the amounts reported in the financial statements, however,
additional disclosures will be required about the inputs used to develop the
measurements of fair value and the effect of certain measurements reported on
the Statement of Operations for a fiscal period.

The returns shown in this report do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Performance of share classes will vary due to differences in sales charges and
expenses. Average annual total return with sales charges includes payment of the
maximum sales charge of 4.75 percent for Class A shares, a contingent deferred
sales charge of 4.00 percent for Class B shares (in years one and two and
declining to zero after year five), a contingent deferred sales charge of 1.00
percent for Class C shares in year one and combined Rule 12b-1 fees and service
fees of up to 0.25 percent for Class A shares and up to 1.00 percent for Class B
and C shares. The since inception and 10-year returns for Class B shares reflect
the conversion of Class B shares into Class A shares eight years after purchase.
The since inception returns for Class C shares reflects the conversion of Class
C shares into Class A shares ten years after purchase. Class I shares are
available for purchase exclusively by investors through (i) tax-exempt
retirement plans with assets of at least $1 million (including 401(k) plans, 457
plans, employer-sponsored 403(b) plans, profit sharing and money purchase plans,
defined benefit plans and non-qualified deferred compensation plans), (ii)
fee-based investment programs with assets of at least $1 million, (iii)
qualified state tuition plan (529 plan) accounts, (iv) institutional clients
with assets of at least $1 million and (v) certain Van Kampen investment
companies. Class I shares are offered without any sales charges on purchases or
sales and do not include combined Rule 12b-1 fees and service fees. Periods of
less than one year are not annualized. Figures shown above assume reinvestment
of all dividends and capital gains. The fund's adviser has waived or reimbursed
fees and expenses from time to time; absent such waivers/reimbursements the
fund's returns would have been lower. SEC 30-day yield is a calculation for
determining the amount of portfolio income, excluding non-income items as
prescribed by the SEC. The unsubsidized SEC 30-day yields reflect some or all of
the expenses that the adviser had voluntarily waived. Yields are subject to
change. The Lehman Brothers Municipal Bond Index is generally representative of
investment-grade, tax-exempt bonds. The index does not include any expenses,
fees or sales charges, which would lower performance. The index is unmanaged and
should not be considered an investment. It is not possible to invest directly in
an index.

Fund Report

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2008

MARKET CONDITIONS

The financial markets experienced significant volatility throughout the six-
month reporting period as many large banks and financial firms began writing
down mortgage-related losses, and liquidity and credit availability became even
more restricted. At the same time, the pace of economic growth began to slow,
with gross domestic product (GDP) growth measuring an anemic 0.6 percent for the
fourth quarter of 2007. As weaker economic data was released in the first
quarter of 2008, fears of recession grew and consumer confidence waned,
prompting investors to continue to seek out the relative safety of high quality
Treasury securities over other sectors of the fixed income market.

The municipal bond market faced additional headwinds as various monoline bond
insurers experienced credit quality downgrades and the auction rate and variable
rate markets deteriorated. As a result, the municipal market underperformed
Treasuries for the overall period, with municipal bond prices reaching the
cheapest levels ever relative to Treasury bonds in the first quarter of 2008.
While yields on short-dated municipal securities declined, yields on
intermediate- and long-dated securities rose, leading to the steepest yield
curve in the past four years as the spread between one-year and 30-year
maturities reached 343 basis points. After a record year for new municipal bond
issuance in 2007, the amount of new issues coming to market in the first quarter
of 2008 declined by roughly 25 percent due in large part to a substantial drop
in refunding issuance.

The Federal Reserve (the "Fed") took various steps to ease the liquidity crisis
and boost the economy during the period. Not only did the Fed reduce the target
federal funds rate from 4.75 percent to 2.25 percent by the end of the period,
but in an unprecedented move, it granted primary brokerage firms access to its
discount window and loosened its collateral requirements, extending loans of
Treasury securities in exchange for lower quality, less liquid securities.
Finally, in the biggest headline event, the Fed arranged and supported JP Morgan
Chase's purchase of Bear Stearns, which was viewed by many as necessary to avoid
serious market repercussions had the firm failed.

The performance for the four share classes varies because each has different
expenses. The Fund's total return figures assume the reinvestment of all
distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and
index definition.

Although the municipal market rebounded in the last month of the reporting
period and outperformed Treasuries, it was an extremely difficult period
overall, particularly for higher yielding, lower-rated bonds as the
flight-to-quality put considerable pressure on prices. The Fund maintained an
allocation to double-B and non-rated bonds throughout the reporting period
whereas the Lehman Brother Municipal Bond Index contains only investment grade
issues. As such, the Fund's overweight to lower rated, higher yielding
securities was a primary contributor to its relative underperformance.

The Fund's yield curve positioning also hindered performance. The Fund was
underweighted in the three-year portion of the curve and overweighted in the
10-year portion of the curve. Over the course of the reporting period, Fed
easing pushed yields on the front end of the yield curve lower while yields on
10-year maturities rose slightly. As a result, the 10-year segment of the curve
underperformed and the Fund's greater relative exposure here held back returns.

Conversely, positions in higher yielding municipal auction rate securities with
low durations (a measure of interest-rate sensitivity) were additive to
performance for the period, as was the Fund's overall shorter duration.
Underweighted positions in housing and tobacco bonds were also beneficial as
spread widening in the sectors hurt their performance.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the Fund in
the future.

                                                                               7


Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and Class C
Shares; and redemption fees; and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees; and other Fund expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 10/1/07 - 3/31/08.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing cost of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or contingent deferred sales charges or redemption fees.
Therefore, the second line of the table is useful in comparing ongoing costs
only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
costs would have been higher.

VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Intermediate Term Municipal Income Fund (the "Fund") is organized as
a series of the Van Kampen Tax Free Trust, a Delaware statutory 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 with a high level of current income
exempt from federal income tax, consistent with preservation of capital. The
Fund commenced investment operations on May 28, 1993. The Fund offers Class A
Shares, Class B Shares, Class C Shares and Class I Shares. Each class of shares
differs by its initial sales load, contingent deferred sales charges, the
allocation of class specific expenses and voting rights on matters affecting a
single class.

    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 U.S. generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION 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.
Futures contracts are valued at the settlement price established each day on the
exchange on which they are traded. 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.
Legal expenditures that are expected to result in the restructuring of or a plan
of reorganization for an investment are recorded as realized losses. 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 segregate
assets with the custodian 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, 2008, the Fund had $4,333,510 of when-issued or delayed
delivery purchase commitments.

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
incremental transfer agency costs which are unique to each class of shares.

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no

                                                                              27


VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

provision for federal income taxes is required. The Fund adopted the provisions
of the Financial Accounting Standards Board ("FASB") Interpretation No. 48 ("FIN
48") Accounting for Uncertainty in Income Taxes on March 31, 2008. FIN 48 sets
forth a minimum threshold for financial statement recognition of the benefit of
a tax position taken or expected to be taken in a tax return. The implementation
of FIN 48 did not result in any unrecognized tax benefits in the accompanying
financial statements. If applicable, the Fund recognizes interest accrued
related to unrecognized tax benefits in "Interest Expense" and penalties in
"Other" expenses on the Statement of Operations. The Fund files tax returns with
the U.S. Internal Revenue Service, New York and various states. Generally, each
of the tax years in the four year period ended September 30, 2007, remains
subject to examination by taxing authorities.

    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, 2007, the Fund had an accumulated capital loss
carryforward for tax purposes of $54,717, which will expire on September 30,
2015.

    At March 31, 2008, the cost and related gross unrealized appreciation and
depreciation were as follows:

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 at least annually. Distributions from net realized gains for book
purposes may include short-term capital gains and gains on futures transactions.
All short-term capital gains and a portion of futures gains are included in
ordinary income for tax purposes.

    The tax character of distributions paid during the year ended September 30,
2007 was as follows.

F. CREDITS EARNED ON CASH BALANCES During the six months ended March 31, 2008,
the Fund's custody fee was reduced by $683 as a result of credits earned on cash
balances.

G. FLOATING RATE NOTE OBLIGATIONS RELATED TO SECURITIES HELD The Fund enters
into transactions in which it transfers to dealer trusts fixed rate bonds in
exchange for cash and residual interest in the dealer trusts' assets and cash
flows, which are in the form of inverse floating rate investments. The dealer
trusts fund the purchases of the fixed rate bonds by issuing floating rate notes
to third parties and allowing the Fund to retain residual interests in the
bonds. The Fund enters into shortfall agreements with the dealer trusts, which
commit the Fund to pay the dealer trusts, in certain circumstances, the
difference between the liquidation value of the fixed rate bonds held by the
dealer trusts and the liquidation value of the floating rate notes held by third
parties, as well as any shortfalls in interest cash flows. The residual
interests held by the Fund (inverse floating rate investments) include the right
of the Fund (1) to cause the holders of the floating rate notes to tender their
notes at par at the next interest rate reset date, and (2) to transfer the
municipal bond from the dealer trusts to the Fund, thereby collapsing the dealer
trusts. The Fund accounts for the transfer of bonds to the dealer trusts as
secured borrowings, with the securities transferred remaining in the Fund's
investments assets, and the related floating rate notes reflected as Fund
liabilities under the caption "Floating Rate Note Obligations" on the Statement
of Assets and Liabilities. The Fund records the interest income from the fixed
rate bonds under the caption "Interest" and records the expenses related to
floating rate note obligations and any administrative expenses of the dealer
trusts under the caption "Interest and Residual Trust Expenses" on the Fund's
Statement of Operations. The notes issued by the dealer trust have interest
rates that reset weekly and the floating rate note holders have the option to
tender their notes to the dealer trusts for redemption at par at each reset
date. At March 31, 2008, Fund investments with a value of $2,595,962 are held by
the dealer trusts and serve as collateral for the $1,875,000 in floating rate
notes outstanding at that date. Contractual maturities of the floating rate
notes and interest rates in effect at March 31, 2008 are presented on the
Portfolio of Investments. The average floating rate notes outstanding and
average annual interest and fee rate related to residual interests during the
six months ended March 31, 2008 were $535,714 and 2.02%, respectively.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset
Management (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, 2008, the Adviser voluntarily waived
$55,400 of its investment advisory fees. This represents .10% of its average
daily net assets for the period. This waiver is voluntary and can be
discontinued at any time.

    For the six months ended March 31, 2008, the Fund recognized expenses of
approximately $4,700 representing legal services provided by Skadden, Arps,
Slate, Meagher &

                                                                              29


VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

Flom LLP, of which a trustee of the Fund is a partner of such firm and he and
his law firm provide legal services as legal counsel to the Fund.

    Under separate Legal Services, Accounting Services and Chief Compliance
Officer (CCO) Employment Agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Fund. The costs of
these services are allocated to each fund. For the six months ended March 31,
2008, the Fund recognized expenses of approximately $26,600 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, as well as the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Professional Fees" on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Accounting and Administrative Expenses" on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the six months ended
March 31, 2008, the Fund recognized expenses of approximately $16,000
representing transfer agency fees paid to VKIS and its affiliates. The transfer
agency fees are determined through negotiations with the Fund's Board of
Trustees.

    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 also
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 $132,421 are included in
"Other" assets on the Statements of Assets and Liabilities at March 31, 2008.
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.

    For the six months ended March 31, 2008, Van Kampen, as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $11,100 and contingent deferred sales charge (CDSC) on redeemed
shares of approximately $8,500. Sales charges do not represent expenses of the
Fund.

    At March 31, 2008, Morgan Stanley Investment Management, Inc., an affiliate
of the Adviser, owned 951 shares of Class I Shares.

4. REDEMPTION FEE

The Fund will assess a 2% redemption fee on the proceeds of Fund shares that are
redeemed (either by sale or exchange) within seven days of purchase. The
redemption fee is paid directly to the Fund and allocated on a pro rata basis to
each class of shares. For the six months ended March 31, 2008, the Fund received
redemption fees of approximately $15,600 which are reported as part of "Cost of
Shares Repurchased" on the Statement of Changes in Net Assets. The per share
impact from redemption fees paid to the Fund was less than $0.01.

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $40,576,101 and $23,187,599,
respectively.

6. 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 may use derivative instruments for a variety of reasons, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio, to manage the portfolio's effective yield, maturity and duration, or
generate potential gain. All of the Fund's

                                                                              31


VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

portfolio holdings, including derivative instruments, are marked to market each
day with the change in value reflected in unrealized appreciation/depreciation.
Upon disposition, a realized gain or loss is recognized accordingly, except when
taking delivery of a security underlying a futures contract. In these instances,
the recognition of gain or loss is postponed until the disposal of the security
underlying the futures contract. Risks may arise as a result of the potential
inability of the counter parties to meet the terms of their contracts.

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

A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in exchange traded futures contracts on U.S. Treasury
Securities and typically closes the contract prior to delivery date. Upon
entering into futures contracts, the Fund maintains an amount of cash or liquid
securities with a value equal to a percentage of the contract amount with either
a futures commission merchant pursuant to rules and regulations promulgated
under the 1940 Act, as amended, or with its custodian in an account in the
broker's name. This amount is known as initial margin. During the period the
futures contract is open, payments are received from or made to the broker based
upon changes in the value of the contract (the variation margin). The risk of
loss associated with a futures contract is in excess of the variation margin
reflected on the Statement of Assets and Liabilities. There were no futures
transactions entered into during the six months ended March 31, 2008.

B. INVERSE FLOATING RATE INVESTMENTS The Fund may invest a portion of its assets
in inverse floating rate instruments, either through outright purchases of
inverse floating rate securities or through the transfer of bonds to a dealer
trust in exchange for cash and residual interests in the dealer trust. These
investments are typically used by the Fund in seeking to enhance the yield of
the portfolio. These instruments typically involve greater risks than a fixed
rate municipal bond. In particular, these instruments are acquired through
leverage or may have leverage embedded in them and therefore involve many of the
risks associated with leverage. Leverage is a speculative technique that my
expose the Fund to greater risk and increased costs. Leverage may cause the
Fund's net asset value to be more volatile than if it had not been leveraged
because leverage tends to magnify the effect of any increases or decreases in
the value of the Fund's portfolio securities. The use of leverage may also cause
the Fund to liquidate portfolio positions when it may not be advantageous to do
so in order to satisfy its obligations with respect to inverse floating rate
instruments.

7. DISTRIBUTIONS AND SERVICE PLANS

Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"),
an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant
to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively,
the "Plans") for Class A Shares, Class B Shares and Class C Shares to compensate
the Distributor for the sale, distribution, shareholder servicing and
maintenance of shareholder accounts for these shares. Under the Plans, the Fund
will incur annual fees of up to .25% of Class A average daily net assets and up
to 1.00% each of Class B and Class C average daily net assets. These fees are
accrued daily and paid to the Distributor monthly.

 32


VAN KAMPEN INTERMEDIATE TERM MUNICIPAL INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

    The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed receivable") was approximately $0 and $200 for Class B
and Class C Shares, respectively. These amounts may be recovered from future
payments under the distribution plan or CDSC. To the extent the unreimbursed
receivable has been fully recovered, the distribution fee is reduced.

8. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

9. ACCOUNTING PRONOUNCEMENT

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. As of March 31, 2008, the Adviser does not believe the adoption of
SFAS 157 will impact the amounts reported in the financial statements, however,
additional disclosures will be required about the inputs used to develop the
measurements of fair value and the effect of certain measurements reported on
the Statement of Operations for a fiscal period.

                                                                              33

PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS, AND CURRENT PERFORMANCE MAY
BE LOWER OR HIGHER THAN THE FIGURES SHOWN. FOR THE MOST RECENT MONTH-END
PERFORMANCE FIGURES, PLEASE VISIT VANKAMPEN.COM OR SPEAK WITH YOUR FINANCIAL
ADVISOR. INVESTMENT RETURNS AND PRINCIPAL VALUE WILL FLUCTUATE AND FUND SHARES,
WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST.

The returns shown in this report do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Performance of share classes will vary due to differences in sales charges and
expenses. Average annual total return with sales charges includes payment of the
maximum sales charge of 4.75 percent for Class A shares, a contingent deferred
sales charge of 4.00 percent for Class B shares (in year one and declining to
zero after year six), a contingent deferred sales charge of 1.00 percent for
Class C shares in year one and combined Rule 12b-1 fees and service fees of up
to 0.25 percent for Class A shares and up to 1.00 percent for Class B and C
shares. The since inception and 10-year returns for Class B shares reflect its
conversion into Class A shares eight years after purchase. The since inception
returns for Class C shares reflects the conversion of Class C shares into Class
A shares ten years after purchase. Figures shown above assume reinvestment of
all dividends and capital gains. The fund's adviser has waived or reimbursed
fees and expenses from time to time; absent such waivers/reimbursements the
fund's returns would have been lower. Periods less than one year are not
annualized. SEC yield is a calculation for determining the amount of portfolio
income, excluding non-income items as prescribed by the SEC. The unsubsidized
SEC yields reflect some or all of the expenses that the adviser had voluntarily
waived. Yields are subject to change.

The Lehman Brothers Municipal Bond Index is generally representative of
investment-grade, tax-exempt bonds. The Lehman Brothers NY Municipal Bond Index
tracks the performance of NY issued municipal bonds rated at least Baa or BBB by
Moody's Investors Service, Inc. or Standard & Poor's Corporation, respectively
and with maturities of 2 years or greater. Indexes do not include any expenses,
fees or sales charges, which would lower performance. Indexes are unmanaged and
should not be considered an investment. It is not possible to invest directly in
an index.

Fund Report

FOR THE SIX-MONTH PERIOD ENDED MARCH 31, 2008

MARKET CONDITIONS

The financial markets experienced significant volatility throughout the six-
month reporting period as many large banks and financial firms began writing
down mortgage-related losses, and liquidity and credit availability became even
more restricted. At the same time, the pace of economic growth began to slow,
with gross domestic product (GDP) growth measuring an anemic 0.6 percent for the
fourth quarter of 2007. As weaker economic data was released in the first
quarter of 2008, fears of recession grew and consumer confidence waned,
prompting investors to continue to seek the relative safety of high-quality
Treasury securities over other sectors of the fixed income market.

The municipal bond market faced additional headwinds as various monoline bond
insurers experienced credit quality downgrades and the auction rate and variable
rate markets deteriorated. As a result, the municipal market underperformed
Treasuries for the overall period, with municipal bond prices reaching
historically attractive levels relative to Treasury bonds in the first quarter
of 2008. While yields on short-dated municipal securities declined, yields on
intermediate- and long-dated securities rose, leading to the steepest yield
curve in the past four years as the spread between one-year and 30-year
maturities reached 343 basis points. After a record year for new municipal bond
issuance in 2007, the amount of new issues coming to market in the first quarter
of 2008 declined by roughly 25 percent due in large part to a substantial drop
in refunding issuance. Although issuance by the State of New York declined as
well, it remained one of the largest issuers of municipal bonds in the country.

The Federal Reserve (the "Fed") took various steps to ease the liquidity crisis
and boost the economy during the period. Not only did the Fed reduce the target
federal funds rate from 4.75 percent to 2.25 percent by the end of the period,
but in an unprecedented move, it granted primary brokerage firms access to its
discount window and loosened its collateral requirements, extending loans of
Treasury securities in exchange for lower quality, less liquid securities.
Finally, in the biggest headline event, the Fed facilitated JPMorgan Chase's
purchase of Bear Stearns, which was viewed by many as necessary to avoid serious
market repercussions had the firm failed.

The performance for the three share classes varies because each has different
expenses. The Fund's total return figures assume the reinvestment of all
distributions, but do not reflect the deduction of any applicable sales charges.
Such costs would lower performance. Past performance is no guarantee of future
results. See Performance Summary for standardized performance information and
index definitions.

Various factors contributed to the Fund's performance during the period. The
primary detractors from performance were holdings in the health care, housing
and tobacco sectors. Although credit spreads in all sectors of the municipal
market widened during the period, these three sectors experienced greater
widening than most and the Fund's overweights there versus the Lehman Brothers
New York Municipal Bond Index and the Lehman Brothers Municipal Bond Index
hindered relative returns. Additionally, some of these positions were held in
the form of inverse floating-rate securities*, which are highly sensitive to
interest rate changes and therefore, amplified the negative impact of spread
widening. The inverse floaters did, however, serve to enhance the Fund's income
and diversification during the period. The Fund's overweight allocation to
industrial development revenue/pollution control revenue bonds also held back
performance, as did security selection within the sector.

Over the course of the period, we sought to enhance the Fund's yield by
maintaining an emphasis on higher-yielding, lower-rated bonds and bonds with
longer maturities. In particular, the Fund was overweighted BBB and non-rated
bonds, which held back returns as the higher-quality segment of the market
outperformed. The Fund's focus on bonds with maturities of 25 years or more also
hindered performance as rates on the long end of the curve moved higher during
the period.

Other investments, however, had a positive effect on relative performance.
Strong security selection as well as an underweight in insured bonds was
beneficial as the credit downgrades of various monoline bond insurers put
pressure on prices in the sector. An overweight to pre-refunded bonds was
additive to performance as well. These high-quality, shorter-maturity issues

                                                                               3


benefited as the short end of the curve outpaced the long end during the
reporting period.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the Fund in
the future.

*   An inverse floating-rate security, or "inverse floater", is a variable rate
    security whose coupon rate changes in the opposite direction from the change
    in the reference rate used to calculate the coupon rate.

Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments of Class A Shares
and contingent deferred sales charges on redemptions of Class B and Class C
Shares; and redemption fees; and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees; and other Fund expenses. This example is
intended to help you understand your ongoing costs (in dollars) of investing in
the Fund and to compare these costs with the ongoing costs of investing in other
mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 10/1/07 - 3/31/08.

ACTUAL EXPENSE

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or contingent deferred sales charges or redemption fees.
Therefore, the second line of the table is useful in comparing ongoing costs
only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
costs would have been higher.

VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen New York Tax Free Income Fund (the "Fund") is organized as a series
of the Van Kampen Tax Free Trust, a Delaware statutory 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 investors with a high level of current income
exempt from federal, New York State and New York City income taxes, consistent
with the preservation of capital. The Fund seeks to achieve its investment
objective by investing primarily in a portfolio of New York municipal securities
that are rated investment grade at the time of purchase. The Fund commenced
investment operations on July 29, 1994. The Fund offers Class A Shares, Class B
Shares, Class C Shares and Class I Shares. Each class of shares differs by its
initial sales load, contingent deferred sales charges, the allocation of class
specific expenses and voting rights on matters affecting a single class. As of
March 31, 2008, there have been no sales of Class I Shares.

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

A. SECURITY VALUATION 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.
Futures contracts are valued at the settlement price established each day on the
exchange on which they are traded. Interest rate swaps are valued using market
quotations from brokers. 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
segregate assets with the custodian 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, 2008, 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 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
incremental transfer agency costs which are unique to each class of shares.

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of Subchapter M 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 adopted the provisions of the Financial Accounting Standards Board ("FASB")
Interpretation No. 48 ("FIN 48") Accounting for Uncertainty in Income Taxes on
March 31, 2008. FIN 48 sets forth a minimum threshold for financial statement
recognition of the benefit of a tax position taken or expected to be taken in a
tax return. The implementation of FIN 48 did not result in any unrecognized tax
benefits in the accompanying financial statements. If applicable, the Fund
recognizes interest accrued related to unrecognized tax benefits in "Interest
Expense" and penalties in "Other" expenses on the Statement of Operations. The
Fund files tax returns with the U.S. Internal Revenue Service, New York and
various states. Generally, each of the tax years in the four year period ended
September 30, 2007, remains subject to examination by taxing authorities.

    At March 31, 2008, the cost and related gross unrealized appreciation and
depreciation were as follows:

</Table>

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares and pays monthly dividends
from net investment income. Net realized gains, if any, are distributed at least
annually. Distributions from net realized gains for book purposes may include
short-term capital gains and gains on futures transactions. All short-term
capital gains and a portion of futures gains are included as ordinary income for
tax purposes.

    The tax character of distributions paid during the year ended September 30,
2007 was as follows:

<Table>

  Ordinary income...........................................  $    7,504
  Tax-exempt income.........................................   4,864,884

                                                              ----------
                                                              $5,053,388
                                                              ==========
</Table>

    As of September 30, 2007, the components of distributable earnings on a tax
basis were as follows:

<Table>

Undistributed tax-exempt income.............................   615,974
Undistributed long-term capital gain........................   141,267
</Table>

    Net realized gains or losses may differ for financial reporting and tax
purposes primarily as a result of gains or losses recognized on securities for
tax purposes but not for book purposes.

                                                                              23

F. CREDITS EARNED ON CASH BALANCES During the six months ended March 31, 2008,
the Fund's custody fee was reduced by $1,218 as a result of credits earned on
cash balances.

G. FLOATING RATE NOTE OBLIGATIONS RELATED TO SECURITIES HELD The Fund enters
into transactions in which it transfers to dealer trusts fixed rate bonds in
exchange for cash and residual interests in the dealer trusts' assets and cash
flows, which are in the form of inverse floating rate investments. The dealer
trusts fund the purchases of the fixed rate bonds by issuing floating rate notes
to third parties and allowing the Fund to retain residual interests in the
bonds. The Fund enters into shortfall agreements with the dealer trusts, which
commit the Fund to pay the dealer trusts, in certain circumstances, the
difference between the liquidation value of the fixed rate bonds held by the
dealer trusts and the liquidation value of the floating rate notes held by third
parties, as well as any shortfalls in interest cash flows. The residual
interests held by the Fund (inverse floating rate investments) include the right
of the Fund (g) to cause the holders of the floating rate notes to tender their
notes at par at the next interest rate reset date, and (2) to transfer the
municipal bond from the dealer trusts to the Fund, thereby collapsing the dealer
trusts. The Fund accounts for the transfer of bonds to the dealer trusts as
secured borrowings, with the securities transferred remaining in the Fund's
investment assets, and the related floating rate notes reflected as Fund
liabilities under the caption "Floating Rate Note Obligations" on the Statement
of Assets and Liabilities. The Fund records the interest income from the fixed
rate bonds under the caption "Interest" and records the expenses related to
floating rate note obligations and any administrative expenses of the dealer
trusts under the caption "Interest and Residual Trust Expenses" in the Fund's
Statement of Operations. The notes issued by the dealer trusts have interest
rates that reset weekly and the floating rate note holders have the option to
tender their notes to the dealer trusts for redemption at par at each reset
date. At March 31, 2008, Fund investments with a value of $7,928,385 are held by
the dealer trusts and serve as collateral for the $6,000,000 in floating rate
notes outstanding at that date. Contractual maturities of the floating rate
notes and interest rates in effect at March 31, 2008 are presented on the
Portfolio of Investments. The average floating rate notes outstanding and
average annual interest and fee rate related to residual interests during the
six months ended March 31, 2008 were $3,857,143 and 5.91%, respectively.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen Asset
Management ("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..........................................     .470%
Over $500 million...........................................     .445%
</Table>

    For the six months ended March 31, 2008, the Adviser voluntarily waived
$147,300 of its investment advisory fees. This represents .25% of its average
daily net assets for the period. This waiver is voluntary and can be
discontinued at any time.

    For the six months ended March 31, 2008, the Fund recognized expenses of
approximately $9,200 representing legal services provided by Skadden, Arps,
Slate, Meagher &

 24


VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

Flom LLP, of which a trustee of the Fund is a partner of such firm and he and
his law firm provide legal services as legal counsel to the Fund.

    Under separate Legal Services, Accounting Services and Chief Compliance
Officer (CCO) Employment agreements, the Adviser provides accounting and legal
services and the CCO provides compliance services to the Fund. The costs of
these services are allocated to each fund. For the six months ended March 31,
2008, the Fund recognized expenses of approximately $17,700 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Fund, as well as the salary,
benefits and related costs of the CCO and related support staff paid by Van
Kampen. Services provided pursuant to the Legal Services agreement are reported
as part of "Professional Fees" on the Statement of Operations. Services provided
pursuant to the Accounting Services and CCO Employment agreement are reported as
part of "Accounting and Administrative Expenses" on the Statement of Operations.

    Van Kampen Investor Services Inc. (VKIS), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the six months ended
March 31, 2008, the Fund recognized expenses of approximately $13,800
representing transfer agency fees paid to VKIS and its affiliates. The transfer
agency fees are determined through negotiations with the Fund's Board of
Trustees.

    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 also
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 $82,508 are included in
"Other" assets on the Statement of Assets and Liabilities at March 31, 2008.
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.

    For the six months ended March 31, 2008, Van Kampen, as Distributor for the
Fund, received commissions on sales of the Fund's Class A Shares of
approximately $14,100 and contingent deferred sales charge (CDSC) on redeemed
shares of approximately $18,800. Sales charges do not represent expenses of the
Fund.

                                                                              25

4. REDEMPTION FEE

The Fund will assess a 2% redemption fee on the proceeds of Fund shares that are
redeemed (either by sale or exchange) within seven days of purchase. The
redemption fee is paid directly to the Fund and allocated on a pro rata basis to
each class of shares. For the six months ended March 31, 2008, the Fund did not
receive any redemption fees.

5. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $14,160,188 and $14,613,124,
respectively.

6. 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 may use derivative instruments for a variety of reasons 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 maturity and duration. All of
the Fund's portfolio holdings, including derivative instruments, are marked to
market each day with the change in value reflected in the unrealized
appreciation/depreciation. Upon disposition, a realized gain or loss is
recognized accordingly, except when taking delivery of a security underlying a
futures

 26


VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

contract. In these instances, the recognition of gain or loss is postponed until
the disposal of the security underlying the futures contract.

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

A. FUTURES CONTRACTS The Fund may invest in futures contracts, a type of
derivative investment. A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in exchange traded futures contracts on U.S. Treasury
Bonds or Notes and typically closes the contract prior to the delivery date.
Upon entering into futures contracts, the Fund maintains an amount of cash or
liquid securities with a value equal to a percentage of the contract amount with
either a futures commission merchant pursuant to rules and regulations
promulgated under the 1940 Act, as amended, or with its custodian in an account
in the broker's name. This amount is known as initial margin. During the period
the futures contract is open, payments are received from or made to the broker
based upon changes in the value of the contract (the variation margin). The risk
of loss associated with a futures contract is in excess of the variation margin
reflected on the Statement of Assets and Liabilities.

    There were no futures transactions entered into during the six months ended
March 31, 2008.

B. INVERSE FLOATING RATE INVESTMENTS The Fund may invest a portion of its assets
in inverse floating rate instruments, either through outright purchases of
inverse floating rate securities or through the transfer of bonds to a dealer
trust in exchange for cash and residual interests in the dealer trust. These
investments are typically used by the Fund in seeking to enhance the yield of
the portfolio. These instruments typically involve greater risks than a fixed
rate municipal bond. In particular, these instruments are acquired through
leverage or may have leverage embedded in them and therefore involve many of the
risks associated with leverage. Leverage is a speculative technique that may
expose the Fund to greater risk and increased costs. Leverage may cause the
Fund's net asset value to be more volatile than if it had not been leveraged
because leverage tends to magnify the effect of any increases or decreases in
the value of the Fund's portfolio securities. The use of leverage may also cause
the Fund to liquidate portfolio positions when it may not be advantageous to do
so in order to satisfy its obligations with respect to inverse floating rate
instruments.

C. INTEREST RATE SWAPS The Fund may enter into forward interest rate swap
transactions intended to help the Fund manage its overall interest rate
sensitivity, either shorter or longer, generally to more closely align the
Fund's interest rate sensitivity with that of the broader municipal market.
Forward interest rate swap transactions involve the Fund's agreement with a
counterparty to pay, in the future, a fixed or variable rate payment in exchange
for the counterparty paying the Fund a variable or fixed rate payment, the
accruals for which would begin at a specified date in the future (the "effective
date"). The amount of the payment obligation is based on the notional amount of
the forward swap contract and the termination date of the swap (which is akin to
a bond's maturity). The value of the Fund's swap commitment would increase or
decrease based primarily on the extent to which long-term interest rates for
bonds having a maturity of the swap's termination date increases or decreases.
The Fund may terminate a swap contract prior to the effective date, at which
point

                                                                              27


VAN KAMPEN NEW YORK TAX FREE INCOME FUND

NOTES TO FINANCIAL STATEMENTS -- MARCH 31, 2008 (UNAUDITED) continued

a realized gain or loss is recognized. When a forward swap is terminated, it
ordinarily does not involve the delivery of securities or other underlying
assets or principal, but rather is settled in cash on a net basis. The Fund
intends, but is not obligated, to terminate its forward swaps before the
effective date. Accordingly, the risk of loss with respect to the swap
counterparty on such transactions is limited to the credit risk associated with
a counterparty failing to honor its commitment to pay any realized gain to the
Fund upon termination. To reduce such credit risk, all counterparties are
required to pledge collateral daily (based on the daily valuation of each swap)
on behalf of the Fund with a value approximately equal to the amount of any
unrealized gain. Reciprocally, when the Fund has an unrealized loss on a swap
contract, the Fund has instructed the custodian to pledge cash or liquid
securities as collateral with a value approximately equal to the amount of the
unrealized loss. Collateral pledges are monitored and subsequently adjusted if
and when the swap valuations fluctuate. Restricted cash, if any, for segregating
purposes is shown on the Statement of Assets and Liabilities.

7. DISTRIBUTION AND SERVICE PLANS

Shares of the Fund are distributed by Van Kampen Funds Inc. (the "Distributor"),
an affiliate of the Adviser. The Fund has adopted a distribution plan pursuant
to Rule 12b-1 under the 1940 Act, as amended, and a service plan (collectively,
the "Plans") for Class A Shares, Class B Shares and Class C Shares to compensate
the Distributor for the sale, distribution, shareholder servicing and
maintenance of shareholder accounts for these shares. Under the Plans, the Fund
will incur annual fees of up to .25% of Class A average daily net assets and up
to 1.00% each of Class B and Class C average daily net assets. These fees are
accrued daily and paid to the Distributor monthly.

    The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed receivable") was approximately $0 and $10,800 for
Class B and Class C Shares, respectively. These amounts may be recovered from
future payments under the distribution plan or CDSC. To the extent the
unreimbursed receivable has been fully recovered, the distribution fee is
reduced.

8. INDEMNIFICATIONS

The Fund enters into contracts that contain a variety of indemnifications. The
Fund's maximum exposure under these arrangements is unknown. However, the Fund
has not had prior claims or losses pursuant to these contracts and expects the
risk of loss to be remote.

9. ACCOUNTING PRONOUNCEMENT

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. As of March 31, 2008, the Adviser does not believe the adoption of
SFAS 157 will impact the amounts reported in the financial statements, however,
additional disclosures will be required about the inputs used to develop the
measurements of fair value and the effect of certain measurements reported on
the Statement of Operations for a fiscal period.
