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 ADVISER. INVESTMENT RETURNS, NET
ASSET VALUE (NAV) AND COMMON SHARE MARKET PRICE WILL FLUCTUATE AND TRUST SHARES,
WHEN SOLD, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST.

NAV per share is determined by dividing the value of the trust's portfolio
securities, cash and other assets, less all liabilities and preferred shares, by
the total number of common shares outstanding. The common share market price is
the price the market is willing to pay for shares of the trust at a given time.
Common share market price is influenced by a range of factors, including supply
and demand and market conditions. Total return assumes an investment at the
beginning of the period, reinvestment of all distributions for the period in
accordance with the trust's dividend reinvestment plan, and sale of all shares
at the end of the period. The trust's adviser has waived or reimbursed fees and
expenses from time to time; absent such waivers/reimbursements the trust's
returns would have been lower.

The Lehman Brothers Municipal Bond Index is a broad-based statistical composite
of municipal 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.

Trust Report

FOR THE SIX-MONTH PERIOD ENDED APRIL 30, 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, which caused spreads to widen,
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 four months of 2008 declined by roughly nine percent versus
the same period one year earlier due in part to a drop in refunding issuance.
Insured bond issuance declined as well.

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 4.50 percent to 2.00 percent
by the end of the period, but in an unprecedented move, the Fed granted primary
Treasury dealers (mainly 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 JPMorgan Chase's purchase of Bear
Stearns, which was viewed by many as necessary to avoid serious market
repercussions had the firm failed.

PERFORMANCE ANALYSIS

The Trust's return can be calculated based upon either the market price or the
net asset value (NAV) of its shares. NAV per share is determined by dividing the
value of the Trust's portfolio securities, cash and other assets, less all
liabilities and preferred shares, by the total number of common shares
outstanding, while market price reflects the supply and demand for the shares.
As a result, the two returns can differ, as they did during the reporting
period. On both an NAV basis and a market price basis, the Trust underperformed
its benchmark index, the Lehman Brothers Municipal Bond Index.

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. Investment return, net asset value and common share market price will
fluctuate and Trust shares, when sold, may be worth more or less than their
original cost. See Performance Summary for additional performance information
and index definition.

Although the period under review was difficult for the municipal bond market
overall, the insured sector in particular struggled as the credit rating
downgrades of various monoline bond insurers put considerable pressure on
prices. Rising rates in the intermediate and long portions of the municipal
yield curve further hindered the performance of these more interest-rate
sensitive securities. These factors were the primary contributors to the Trust's
underperformance relative to the Lehman Brothers Municipal Bond Index as the
Trust maintained its approximate 85 percent allocation to insured bonds whereas
the benchmark contains no insured bonds. Given the credit downgrades of certain
insurers, we believed it was prudent to purchase additional insurance on various
bonds held in the portfolio. We bought this insurance as a precautionary measure
from a company that has not been downgraded; the underlying AAA credit quality
of the reinsured bonds in our view remains intact.

Over the course of the period we continued with our efforts to enhance the
Trust's yield through various strategies. One of these was to maintain an
approximate 15 percent allocation to uninsured--yet still investment
grade--securities. (The Trust can invest up to 20 percent of assets in such
securities.) Many of these were held in the form of inverse floating-rate
securities* in the tobacco, health care, and housing sectors. Although these
higher-yielding securities served to enhance the Trust's income and
diversification, spread widening in all three sectors hurt their performance.
Additionally,

*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.
                                                                               3


we continued to focus on the long end of the municipal yield curve, favoring
bonds with maturities of 25 years or more for their higher yields, which led to
a longer duration (a measure of interest-rate sensitivity) for the Trust. 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, consequently unwind the hedge prior to the end of the reporting
period.

The Trust's holdings in the transportation sector, and airports in particular,
also held back performance. Record oil and gas prices posed significant
challenges for airlines and while airports themselves have not been directly
affected, the impact was felt across all transportation-related industries,
causing spreads to widen.

Holdings in other sectors, however, contributed positively to performance. The
Trust held an overweight to education bonds, which was beneficial given the
sector's favorable performance during the period. Additionally, allocations to
multi-family housing and resource recovery bonds enhanced performance, as did
pre-refunded bonds which were the largest contributor to returns as these
short-maturity securities benefited from falling rates on the short end of the
yield curve.

The Trustees have approved a procedure whereby the trust may, when appropriate,
repurchase its shares in the open market or in privately negotiated transactions
at a price not above market value or NAV, whichever is lower at the time of
purchase. This may help support the market value of the trust's shares.

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 Trust in
the future.

VAN KAMPEN TRUST FOR INSURED MUNICIPALS

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2008 (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Trust for Insured Municipals (the "Trust") is registered as a
diversified, closed-end management investment company under the Investment
Company Act of 1940 (the "1940 Act"), as amended. The Trust's investment
objective is to seek to provide a high level of current income exempt from
federal income taxes, consistent with preservation of capital. In normal market
conditions, the Trust intends to invest substantially all of its assets in
municipal securities which are covered by insurance with respect to the timely
payment of principal and interest. The Trust commenced investment operations on
January 24, 1992.

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

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the 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
Trust 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 Trust 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 April 30, 2008, the Trust had $15,063,952 of when-issued or
delayed delivery purchase commitments.

C. INVESTMENT INCOME Interest income is recorded on an accrual basis. Bond
premium is amortized and discount is accreted over the expected life of each
applicable security.

D. FEDERAL INCOME TAXES It is the Trust'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
Trust adopted the provisions of the Financial Accounting Standards Board
("FASB") Interpretation No. 48 ("FIN 48") Accounting for Uncertainty in Income
Taxes on April 30, 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

                                                                              23

benefits in the accompanying financial statements. If applicable, the Trust
recognizes interest accrued related to unrecognized tax benefits in "Interest
Expense" and penalties in "Other" expenses on the Statement of Operations. The
Trust 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 October
31, 2007, remains subject to examination by taxing authorities.

    The Trust 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 October 31, 2007, the Trust had an accumulated capital loss
carryforward for tax purposes of $1,942,078, which will expire according to the
following schedule.

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2008 (UNAUDITED) continued

    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.

F. FLOATING RATE NOTE OBLIGATIONS RELATED TO SECURITIES HELD The Trust 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 Trust to retain residual interests in the
bonds. The Trust enters into shortfall agreements with the dealer trusts, which
commit the Trust 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 Trust (inverse floating rate investments) include the
right of the Trust (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 Trust, thereby collapsing the
dealer trusts. The Trust accounts for the transfer of bonds to the dealer trusts
as secured borrowings, with the securities transferred remaining in the Trust's
investment assets, and the related floating rate notes reflected as Trust
liabilities under the caption "Floating Rate Note Obligations" on the Statement
of Assets and Liabilities. The Trust 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 Trust'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 April 30, 2008, Trust investments with a value of $60,753,556 are held
by the dealer trusts and serve as collateral for the $43,455,000 in floating
rate notes outstanding at that date. Contractual maturities of the floating rate
notes and interest rates in effect at April 30, 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 April 30, 2008 were $46,235,714 and 3.43%, respectively.

G. CREDIT EARNED ON CASH BALANCES During the six months ended April 30, 2008,
the Trust's custody fee was reduced by $70 as a result of credit earned on cash
balances.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Trust's Investment Advisory Agreement, Van Kampen Asset
Management (the "Adviser") will provide investment advice and facilities to the
Trust for an annual fee payable monthly of .55% of the average daily net assets
including preferred shares of the Trust. The Adviser has agreed to waive
investment advisory fees equal to 0.10% of the average daily net assets
including preferred shares of the Trust. During the six months ended April 30,
2008, the Adviser waived $114,006 of its advisory fees. This waiver is voluntary
and can be discontinued at any time.

    For the six months ended April 30, 2008, the Trust recognized expenses of
approximately $6,700 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of

                                                                              25

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

    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 Trust. The costs of
these services are allocated to each trust. For the six months ended April 30,
2008, the Trust recognized expenses of approximately $23,400 representing Van
Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of
providing accounting and legal services to the Trust, 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.

    Certain officers and trustees of the Trust are also officers and directors
of Van Kampen. The Trust does not compensate its officers or trustees who are
also officers of Van Kampen.

    The Trust 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 to a
later date. 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 Trust.
The maximum annual benefit per trustee under the plan is $2,500.

</Table>

*   On February 28, 2007, the Trust commenced a share repurchase program for
    purposes of enhancing stockholder value and reducing the discount at which
    the Trust's shares trade from their net asset value. For the six months
    ended April 30, 2008 and the year ended October 31, 2007, the Trust
    repurchased 92,292 and 76,101 of its shares at an average discount of 7.27%
    and 5.85%, respectively from net asset value per share. The Trust expects to
    continue to repurchase its outstanding shares at such time and in such
    amounts as it believes such activity will further the accomplishment of the
    foregoing objectives, subject to the review of the Trustees.

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $68,654,905 and $61,363,745,
respectively.

5. DERIVATIVE FINANCIAL INSTRUMENTS

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

    In order to seek to manage the interest rate exposure of the Trust's
portfolio in a changing interest rate environment, the Trust may purchase or
sell financial futures contracts or engage in transactions involving interest
rate swaps, caps, floors or collars. The Trust expects to enter into these
transactions primarily as a hedge against anticipated interest rate or
fixed-income market changes, for duration management or for risk management
purposes, but may also enter into these transactions to generate additional
income. All of the Trust'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 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 Trust.

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
Trust 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 Trust's effective maturity and
duration. Upon entering into futures contracts, the Trust 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 the 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 April 30, 2008
were as follows:

<Table>
<Caption>
                                                              CONTRACTS
                                                           
Outstanding at October 31, 2007.............................     397
Futures Opened..............................................     370
Futures Closed..............................................    (767)
                                                                ----
Outstanding at April 30, 2008...............................     -0-
                                                                ====
</Table>

B. INTEREST RATE SWAPS The Trust may enter into forward interest rate swap
transactions intended to help the Trust manage its overall interest rate
sensitivity, either shorter or longer, generally to more closely align the
Trust's interest rate sensitivity with that of the broader municipal market.
Forward interest rate swap transactions involve the Trust's agreement with a
counterparty to pay, in the future, a fixed or variable rate payment in exchange
for the counterparty paying the Trust 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

                                                                              27


VAN KAMPEN TRUST FOR INSURED MUNICIPALS

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2008 (UNAUDITED) continued

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 Trust'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 Trust 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 Trust 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 Trust 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 Trust with a value approximately
equal to the amount of any unrealized gain. Reciprocally, when the Trust has an
unrealized loss on a swap contract, the Trust 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.

C. INVERSE FLOATING RATE SECURITIES The Trust 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 Trust 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 Trust to greater risk and increased costs. Leverage may cause the
Trust'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 Trust's portfolio securities. The use of leverage may also
cause the Trust 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.

6. PREFERRED SHARES

The Trust has outstanding 3,600 Auction Preferred Shares (APS) in two series of
1,800 shares each. Dividends are cumulative and the dividend rates are generally
reset every 28 days for both series through an auction process. Beginning on
February 20, 2008 and continuing through April 30, 2008, all series of preferred
shares of the Trust were not successfully remarketed. As a result, the dividend
rates of these preferred shares were reset to the maximum applicable rate on
APS. The average rate in effect on April 30, 2008 was 2.862%. During the six
months ended April 30, 2008, the rates ranged from 2.646% to 5.000%.

    The Trust pays annual fees equivalent to .25% of the preferred share
liquidation value for the remarketing efforts associated with the preferred
auctions. These fees are included as a component of "Preferred Share
Maintenance" expense on the Statement of Operations. The APS are redeemable at
the option of the Trust in whole or in part at the liquidation value of $25,000
per share plus accumulated and unpaid dividends. The Trust is subject to certain

 28


VAN KAMPEN TRUST FOR INSURED MUNICIPALS

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2008 (UNAUDITED) continued

asset coverage tests and the APS are subject to mandatory redemption if the
tests are not met.

7. INDEMNIFICATIONS

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

8. 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 April 30, 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.

    On March 19, 2008, Financial Accounting Standards Board released Statement
of Financial Accounting Standards No. 161, Disclosures about Derivative
Instruments and Hedging Activities (SFAS 161). SFAS 161 requires qualitative
disclosures about objectives and strategies for using derivatives, quantitative
disclosures about fair value amounts of and gains and losses on derivative
instruments, and disclosures about credit-risk-related contingent features in
derivative agreements. The application of SFAS 161 is required for fiscal years
and interim periods beginning after November 15, 2008. At this time, management
is evaluating the implications of SFAS 161 and its impact on the financial
statements has not yet been determined.

9. SUBSEQUENT EVENT

On June 13, 2008, the Trust announced plans for the partial redemption of its
preferred shares. On July 9 and July 8, 2008 the Trust intends to redeem 20% of
each of its Series A and Series B preferred shares, respectively. The Board of
Trustees previously approved the use of tender option bonds as a replacement
source of funding. The Depository Trust Company, the securities' holder of
record, will determine how the partial series redemptions will be allocated
among each participant broker-dealer account.

                                                                              29
