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 Ohio Municipal Bond Index is a broad-based statistical
composite of Ohio 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.
Municipal bond issuance by the state of Ohio was down 21 percent.

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 (mostly 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 Ohio 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 municipal market rebounded in the last two months 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 Trust held an overweight
relative to the Lehman Brothers Ohio Municipal Bond Index in BBB rated
securities, many of which were in the tobacco and health care sectors. The
performance of these securities suffered during the reporting period as spreads
in both sectors widened. As a result, the Trust's holdings here were a primary
contributor to its relative underperformance.

The Trust's yield curve positioning also hindered performance as it was
overweighted on the long end of the municipal yield curve, which underperformed
the shorter end of the curve. The negative impact was amplified somewhat 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 Trust'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 Trust, which we reduced somewhat through the
use of a Treasury futures hedge. However, the Trust still maintained a slightly
longer duration than that of the Lehman Brothers Ohio Municipal Bond Index,
which detracted from performance as rates on the intermediate and long end of
the

*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


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 high-quality, shorter-maturity issues benefited as short-term rates
declined during the period. The Trust's holdings in higher-yielding municipal
auction rate securities (ARS) with low durations were also beneficial to
performance.

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 OHIO QUALITY MUNICIPAL TRUST

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

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Ohio Quality Municipal Trust (the "Trust") is registered as a
non-diversified, closed-end management investment company under the Investment
Company Act of 1940 (the "1940 Act"), as amended, but operates as a diversified
management investment company. The Trust's investment objective is to seek to
provide a high level of current income exempt from federal and Ohio income
taxes, consistent with preservation of capital. The Trust will invest in a
portfolio consisting substantially of Ohio municipal obligations rated
investment grade at the time of investment, but may invest up to 20% of its
assets in unrated securities which are believed to be of comparable quality to
those rated investment grade. The Trust commenced investment operations on
September 27, 1991.

    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 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 $13,407,248 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

                                                                              17


VAN KAMPEN OHIO QUALITY MUNICIPAL TRUST

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

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 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 $1,455,794, which will expire according to the
following schedule:

<Table>

    A portion of the capital loss carryforward above was acquired due to a
merger with another regulated investment company and is subject to annual
limitations.

    At April 30, 2008, the cost and related gross unrealized appreciation and
depreciation were as follows:

E. DISTRIBUTION OF INCOME AND GAINS The Trust declares and pays monthly
dividends from net investment income to common shareholders. Net realized gains,
if any, are distributed at least annually on a pro rata basis to common and
preferred shareholders. Distributions from net realized gains for book purposes
may include short-term capital gains and a portion of futures gains, which are
included as ordinary income for tax purposes.

    The tax character of distributions paid during the year ended October 31,
2007 was as follows:

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" in 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 $38,044,981 are held
by the dealer trusts and serve as collateral for the $27,840,000 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
six months ended April 30, 2008 were $29,470,000 and 2.97%, respectively.

G. CREDITS EARNED ON CASH BALANCES During the six months ended April 30, 2008,
the Trust's custody fee was reduced by $567 as a result of credits 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 0.15% of the average daily net assets
including preferred shares of the Trust. During the six months ended April 30,
2008, the Adviser waived $104,669 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 $3,700 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom LLP, of 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

                                                                              19


VAN KAMPEN OHIO QUALITY MUNICIPAL TRUST

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

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 $20,600 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.

3. CAPITAL TRANSACTIONS

For the six months ended April 30, 2008 and the year ended October 31, 2007,
transactions in common shares were as follows:

</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 31,001 and 19,400, respectively of its shares at an average
    discount of 8.23% and 6.45% 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 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 $53,266,099 and $56,485,091,
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

 20


VAN KAMPEN OHIO QUALITY MUNICIPAL TRUST

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

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. 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 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
Bonds and Notes 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

Futures Closed..............................................    (304)
                                                                ----
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 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

                                                                              21


VAN KAMPEN OHIO QUALITY MUNICIPAL TRUST

NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 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 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 2,000 Auction Preferred Shares (APS). Series A
contains 1,400 shares and Series B contains 600 shares. Dividends are cumulative
and the dividend rates are generally reset every 28 days for Series A, while
Series B are generally reset every 7 days through an auction process. Beginning
on February 15, 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 3.03%. During the
six months ended April 30, 2008, the rates ranged from 2.59% to 4.80%.

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

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

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 16, 2008 and July 2, 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.

                                                                              23
