                             LETTER TO SHAREHOLDERS

May 20, 1999

Dear Shareholder,
    With the volatility that we've experienced in many financial markets in
recent months, some investors have sold securities because of uncertainty about
where the markets were going, only to be left rethinking whether they made the
right decision. We've witnessed this kind of market activity numerous times over
the past several years, sparked by concerns such as the impact of the Asian
economic crisis, high stock valuations, or, most recently, the stability of many
high-flying technology companies. While these fears eventually subsided,
investors who may have sold during this period were unable to reap the benefits
of the latest rally. That's partly because most of the recent big gains happened
in relatively short periods of time. This kind of volatility--and the danger of
making short-term decisions--highlights the importance of investing for the long
term, in accordance with your individual financial objectives.
    Although the worst of the Asian crisis appears to be behind us, new concerns
are always emerging. In the coming months, we'll likely hear more about how the
year 2000 computer problem may affect the markets or that we're overdue for a
correction. While the markets could undoubtedly suffer as a result of these or
any number of other events, we encourage you to focus on your long-term
investment goals. Although nothing is certain, history has shown us that over
time, the markets tend to recover--and most investors want to be positioned to
take advantage of any recovery.
    If you have concerns about market volatility or questions about how your
portfolio is structured to respond to these events, we encourage you to contact
your financial advisor. Your advisor can talk with you about sustaining a
long-term investment plan through a variety of market conditions. We hope that
Van Kampen Funds will play an important role as you and your advisor build a
portfolio designed to help you weather whatever the markets have in store.

Sincerely,


[SIG.]
Richard F. Powers III

                               ECONOMIC SNAPSHOT

    A surge in consumer confidence led to strong economic growth over the past
six months, as fears about the impact of the Asian financial crisis subsided. In
the fourth quarter, the nation's gross domestic product (GDP) rose at an
astounding 6.0 percent annual rate and remained strong at 4.5 percent through
the first quarter of 1999. This powerful level of growth is attributed to a
continued increase in consumer spending, a strong housing market, and high
retail sales--all the result of a more confident consumer given the positive
employment environment. The economy began to show signs of slowing down early in
1999, however, as corporate profits and wage growth declined.
    Despite continued improvements in Asia and Latin America and the record
economic growth in the United States, inflation remained at bay in late 1998 as
commodity prices tumbled. Although rising oil prices pushed inflation up 3.3
percent on an annualized basis in the first four months of 1999, price increases
remained moderate enough overall to keep inflation-adjusted interest rates
attractive.
    Our outlook for the domestic economy remains positive, although we
anticipate slower growth in the second half of the year. We look for a gradual
but steady rise in inflation throughout 1999 to more normal but certainly not
alarming levels. Internationally, low interest rates and improving financial
conditions should continue to support the economic progress we've witnessed
overseas.

                               GLOSSARY OF TERMS

CALL FEATURE: Allows the issuer to buy back a bond on specific dates at set
    prices before maturity. These dates and prices are set when the bond is
    issued. To compensate the bondholder for the potential loss of income and
    ownership, a bond's call price is usually higher than the face value of the
    bond. Bonds are usually called when interest rates drop so significantly
    that the issuer can save money by issuing new bonds at lower rates.

CREDIT RATING: An evaluation of an issuer's credit history and capability of
    repaying obligations. Standard & Poor's and Moody's Investors Service are
    two companies that assign bond ratings. Standard & Poor's ratings range from
    a high of AAA to a low of D, while Moody's ratings range from a high of Aaa
    to a low of C.

DISCOUNT BOND: A bond whose market price is lower than its face value (or "par
    value"). Because bonds usually mature at face value, a discount bond has
    more potential to appreciate in price than a par bond does.

INSURED BOND: A bond that is insured against default by the bond insurer. If the
    issuer defaults, the insurance company will step in and take over payments
    of interest and principal when due. Once a bond is insured, it typically
    carries the rating of the insurer. Most insurers are rated AAA.

INVESTMENT-GRADE BONDS: Securities rated BBB and above by Standard & Poor's or
    Baa and above by Moody's Investors Service. Bonds rated below BBB or Baa are
    noninvestment grade.

MATURITY LENGTH: The time it takes for a bond to mature. A bond issued in 1998
    and maturing in 2008 is a 10-year bond.

MUNICIPAL BOND: A debt security issued by a state, municipality, or other
    government entity to finance capital expenditures of public projects, such
    as the construction of highways, public works, or school buildings. Interest
    on public-purpose municipal bonds is exempt from federal income taxes and,
    in some states, from state and local income taxes.

PREMIUM BOND: A bond whose market price is above its face value (or "par
    value"). Because bonds usually mature at face value, a premium bond has less
    potential to appreciate in price than a par bond does.

REFUNDING: Retiring an outstanding bond issue at maturity using money from the
    sale of a new offering.

YIELD: The annual rate of return on an investment, expressed as a percentage.

YIELD SPREAD: The additional yield investors can earn by either investing in
    bonds with longer maturities or by investing in bonds with lower ratings.
    The spread is the difference in yield between bonds with short versus long
    maturities or the difference in yield between high-quality bonds and
    lower-quality bonds.

                          PORTFOLIO MANAGEMENT REVIEW
                    VAN KAMPEN OHIO QUALITY MUNICIPAL TRUST

We recently spoke with the management team of the Van Kampen Ohio Quality
Municipal Trust about the key events and economic forces that shaped the markets
during the reporting period. The team includes Timothy D. Haney, portfolio
manager, and Peter W. Hegel, chief investment officer for fixed-income
investments. The following comments reflect their views on the Trust's
performance during the six months ended April 30, 1999.

   Q  HOW WOULD YOU DESCRIBE THE CONDITIONS IN THE MUNICIPAL MARKET DURING THE
      PAST SIX MONTHS?

   A  Although most of the financial markets experienced volatility during the
      period, the municipal market remained relatively stable. For the majority
      of the six months, long-term municipal bond yields remained within a range
of about 5.1 to 5.3 percent, even as the Federal Reserve cut interest rates.
Much of the stability in the municipal market can be attributed to its isolation
from turbulence abroad. Concerns about the financial conditions in Asia and
Latin America hurt the stock and high-yield bond markets last fall, but had
little effect on municipals.
    The positive economic and market conditions encouraged more municipalities
to take advantage of low interest rates and issue new bonds. Although the amount
of municipal debt increased, the credit quality of many issuers was not
compromised--in fact, it improved as the positive economic environment led to
stronger balance sheets. As a result, we saw more issuers using municipal bonds
to finance special growth and expansion projects, as opposed to financing their
regular operations.
    The proportion of higher-yielding municipal bonds also increased during the
period as the number of insured bonds declined. Because bond insurers tightened
their underwriting criteria, more issuers came to market without insurance and
offered higher yields to compensate bondholders for the increased credit risk.
This benefited the Trust because it allowed our experienced research staff to
seek out those higher-yielding bonds that we felt had strong underlying quality.
    The financial and economic health of state and local issuers continues to
improve with the expanding economy, particularly in the Columbus and Cleveland
areas. The municipal market in Ohio remains strong, although we have yet to see
the full impact of electric utility deregulation and school finance reform.

   Q  WHY WERE MUNICIPAL BONDS SO ATTRACTIVE RELATIVE TO COMPARABLE TREASURY
      BONDS?

   A  Toward the end of 1998, the yields on 30-year insured municipal bonds and
      comparable U.S. Treasury bonds reached equivalent levels, which is a rare
occurrence. Typically, investment-grade municipal bonds have offered about 85 to
90 percent as much yield as comparable Treasury bonds because their interest
payments are exempt from federal income taxes. However, as Treasury yields fell
and municipal yields remained stable, the yield difference between the two types
of bonds shrank. Early

                                        5
<PAGE>   7

in 1999, investors recognized the tremendous opportunities available in the
municipal market, and demand for municipals began to increase. In conjunction
with a recent slowdown in supply, this boost in municipal demand pushed the
municipal-to-Treasury yield ratio back to more traditional but still attractive
levels.

   Q  WHAT STRATEGIES DID YOU USE TO MANAGE THE TRUST?

   A  Our focus was on supporting the Trust's income stream while monitoring its
      risk level and price volatility. To do so, we sought to limit the Trust's
      exposure to bond calls, which can lower its income stream because we must
invest the proceeds of called bonds into bonds paying current lower interest
rates. During the reporting period, we purchased noncallable bonds, which cannot
be paid off early by their issuers, even if interest rates decline. In addition,
we began to replace some of our housing bonds. These bonds carry a risk that the
mortgage holder will refinance the mortgage or pay it off early, especially
during a low interest-rate environment like we are currently experiencing. As a
result, housing bonds are more likely than many other issues to be called from
the portfolio.
    By working closely with our experienced research analysts, we continued to
look for securities that may be temporarily out of favor but that we feel have
the potential to appreciate in price if market circumstances change. For
example, we purchased 30-year bonds with 5 percent coupon rates--which tend to
attract strong demand from individual investors--during a period where heavy
supply kept prices attractive. A few months later, we sold them at a profit when
the supply of municipal securities declined and demand for these issues
increased. For additional portfolio highlights, please refer to page 8.

   Q  HOW DID THE TRUST PERFORM DURING THE PERIOD?

   A  During the past six months, the Trust generated a total return of 0.92
      percent(1) based on market price. This reflects a decrease in market price
      from $19.0625 per share on October 31, 1998, to $18.6875 on April 30,
1999. In addition, the Trust provided a distribution rate of 5.39 percent(3)
based on its closing common stock price on April 30, 1999. Because the Trust is
exempt from federal and state income taxes, this distribution rate is equivalent
to a yield of 9.04 percent(4) on a taxable investment for shareholders in the
40.4 percent federal and state combined income tax bracket. The Trust's monthly
dividend of $.0840 per share was unchanged during the reporting period. Past
performance does not guarantee future results. Please refer to the footnotes and
chart on page 3 for additional Trust performance results.

<PAGE>   8

   Q  WHAT DO YOU SEE AHEAD FOR THE MUNICIPAL MARKET?

   A  Strong economic performance should continue to bolster the credit
      conditions of municipal issuers. In addition, we expect that this economic
      strength will continue to make municipalities more likely to issue debt
for special projects rather than for general operating financing.
    Although insured debt has been increasing in recent years, we have started
to see a reversal of this trend in the last few months, as municipal bond
insurers have become more cautious. If this caution continues, credit spreads
may widen as the proportion of higher-yielding uninsured bonds increases.
    Finally, we see the potential for changes in traditional economic activity
toward the end of the year because of investor concerns about the year 2000
computer problem. These temporary concerns, however, may result in attractive
investment opportunities that our research staff can explore to uncover
potential value.

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, as amended. The Trust's investment objective is 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 Trust changed its fiscal year-end from August 31 to October 31. As
mentioned in your last report, due to the relatively short span of time between
the August 31, 1998 report and the October 31, 1998 report, the October 31, 1998
report was not distributed but rather the October data is included as part of
this April 30, 1999 semi-annual report.

    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 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 are valued at
fair value using procedures established in good faith by the Board of Trustees.
Short-term securities with remaining maturities of 60 days or less are valued at
amortized cost.

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
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the

                                       18

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                           April 30, 1999 (Unaudited)
- --------------------------------------------------------------------------------

when issued or delayed delivery purchase commitments until payment is made. At
April 30, 1999, there were no when issued or delayed delivery purchase
commitments.

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

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

    The 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, 1998, the Trust had an accumulated capital loss
carryforward for tax purposes of $615 which will expire on October 31, 2006.

    At April 30, 1999, for federal income tax purposes the cost of long- and
short-term investments is $97,396,724, the aggregate gross unrealized
appreciation is $9,612,345 and the aggregate gross unrealized depreciation is
$103,319, resulting in net unrealized appreciation on long- and short-term
investments of $9,509,026.

    At October 31, 1998, for federal income tax purposes the cost of long- and
short-term investments is $97,152,844, the aggregate gross unrealized
appreciation is $11,141,611 and the aggregate gross unrealized depreciation is
$0, resulting in net unrealized appreciation on long- and short-term investments
of $11,141,611.

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 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, which are included as ordinary income for tax
purposes.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
Under the terms of the Trust's Investment Advisory Agreement, Van Kampen
Investment Advisory Corp. (the "Adviser") will provide investment advice and
facilities to the Trust for an annual fee payable monthly of .70% of the average
net assets of the Trust. In addition,

                                       19

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                           April 30, 1999 (Unaudited)
- --------------------------------------------------------------------------------

the Trust will pay a monthly administrative fee to Van Kampen Funds Inc. or its
affiliates (collectively "Van Kampen"), the Trust's Administrator, at an annual
rate of .20% of the average net assets of the Trust. The administrative services
provided by the Administrator include record keeping and reporting
responsibilities with respect to the Trust's portfolio and preferred shares and
providing certain services to shareholders.

    For the six months ended April 30, 1999 and the two-month period ended
October 31, 1998, the Trust recognized expenses of approximately $1,100 and
$600, respectively, representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Trust, of which a trustee of
the Trust is an affiliated person.

    For the six months ended April 30, 1999 and the two-month period ended
October 31, 1998, the Trust recognized expenses of approximately $25,000 and
$10,300, respectively, representing Van Kampen's cost of providing accounting
and legal services to the Trust.

    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
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 for a ten-year period
and are based upon each trustee's years of service to the Trust. The maximum
annual benefit under the plan is $2,500.

3. CAPITAL TRANSACTIONS
At April 30, 1999, October 31, 1998 and August 31, 1998, paid in surplus related
to common shares aggregated $63,103,231, $62,870,027 and $62,791,507,
respectively.

    Transactions in common shares were as follows:

4. INVESTMENT TRANSACTIONS
For the six months ended April 30, 1999, the cost of purchases and proceeds from
sale of investments, excluding short-term investments, were $6,369,754 and
$7,888,596, respectively. For the two months ended October 31, 1998, the cost of
purchases and proceeds from sale of investments, excluding short-term
investments, were $0 and $20,000, respectively.

5. PREFERRED SHARES
Effective with the close of business on April 23, 1999, the liquidation
preference on the Trust's preferred shares decreased from $50,000 to $25,000 per
share. This decrease was effected by means of a 2 for 1 stock split that doubled
the Trust's number of outstanding preferred shares. The total liquidation value
for the Trust was unchanged.

    As of April 30, 1999, the Trust has outstanding 1,400 Auction Preferred
Shares ("APS"). Dividends are cumulative and the dividend rate is currently
reset every 28 days through an auction process. The rate in effect on April 30,
1999 was 3.110%. During the six months ended April 30, 1999, the rates ranged
from 3.000% to 4.980%.

    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.

    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.

<PAGE>   23

                           DIVIDEND REINVESTMENT PLAN

The Trust offers a dividend reinvestment plan (the "Plan") pursuant to which
Common Shareholders may elect to have dividends and capital gains distributions
reinvested in Common Shares of the Trust. The Trust declares dividends out of
net investment income, and will distribute annually net realized capital gains,
if any. Common Shareholders may join or withdraw from the Plan at any time.
    If you decide to participate in the Plan, State Street Bank and Trust
Company, as your Plan Agent, will automatically invest your dividends and
capital gains distributions in Common Shares of the Trust for your account.

HOW TO PARTICIPATE
If you wish to participate and your shares are held in your own name, call
1-800-341-2929 for more information and a Plan brochure. If your shares are held
in the name of a brokerage firm, bank, or other nominee, you should contact your
nominee to see if it would participate in the Plan on your behalf. If you wish
to participate in the Plan, but your brokerage firm, bank or nominee is unable
to participate on your behalf, you should request that your shares be
re-registered in your own name which will enable your participation in the Plan.

HOW THE PLAN WORKS
Participants in the Plan will receive the equivalent in Common Shares valued on
the valuation date, generally at the lower of market price or net asset value,
except as specified below. The valuation date will be the dividend or
distribution payment date or, if that date is not a trading day on the national
securities exchange or market system on which the Common Shares are listed for
trading, the next preceding trading day. If the market price per Common Share on
the valuation date equals or exceeds net asset value per Common Share on that
date, the Trust will issue new Common Shares to participants valued at the
higher of net asset value or 95% of the market price on the valuation date. In
the foregoing situation, the Trust will not issue Common Shares under the Plan
below net asset value. If net asset value per Common Share on the valuation date
exceeds the market price per Common Share on that date, or if the Board of
Trustees should declare a dividend or capital gains distribution payable to the
Common Shareholders only in cash, participants in the Plan will be deemed to
have elected to receive Common Shares from the Trust valued at the market price
on that date. Accordingly, in this circumstance, the Plan Agent will, as agent
for the participants, buy the Trust's Common Shares in the open market for the
participants' accounts on or shortly after the payment date. If, before the Plan
Agent has completed its purchases, the market price exceeds the net asset value
per share of the Common Shares, the average per share purchase price paid by the
Plan Agent may exceed the net asset value of the Trust's Common Shares,
resulting in the acquisition of fewer Common Shares than if the dividend or
distribution had been paid in Common Shares issued by the Trust. All
reinvestments are in full and fractional Common Shares and are carried to three
decimal places.
    Experience under the Plan may indicate that changes are desirable.
Accordingly, the Trust reserves the right to amend or terminate the Plan as
applied to any dividend or distribution paid subsequent to written notice of the
changes sent to all Common Shareholders of the Trust at least 90 days before the
record date for the dividend or distribution. The Plan also may be amended or
terminated by the Plan Agent by at least 90 days written notice to all Common
Shareholders of the Trust.

COSTS OF THE PLAN
The Plan Agent's fees for the handling of the reinvestment of dividends and
distributions will be paid by the Trust. However, each participant will pay a
pro rata share of brokerage commissions incurred with respect to the Plan
Agent's open market purchases in connection with the reinvestment of dividends
and distributions. No other charges will be made to participants for reinvesting
dividends or capital gains distributions, except for certain brokerage
commissions, as described above.

TAX IMPLICATIONS
You will receive tax information annually for your personal records and to help
you prepare your federal income tax return. The automatic reinvestment of
dividends and capital gains distributions does not relieve you of any income tax
which may be payable on dividends or distributions.

RIGHT TO WITHDRAW
Plan participants may withdraw at any time by calling 1-800-341-2929 or by
writing State Street Bank and Trust Company, P.O. Box 8200, Boston, MA
02266-8200. If you withdraw, you will receive, without charge, a share
certificate issued in your name for all full Common Shares credited to your
account under the Plan and a cash payment will be made for any fractional Common
Share credited to your account under the Plan. You may again elect to
participate in the Plan at any time by calling 1-800-341-2929 or writing to the
Trust at:

                         YEAR 2000 READINESS DISCLOSURE

Like other mutual funds, financial and business organizations and individuals
around the world, the Trust could be adversely affected if the computer systems
used by the Trust's investment adviser and other service providers do not
properly process and calculate date-related information and data from and after
January 1, 2000. This is commonly known as the "Year 2000 Problem." The Trust's
investment adviser is taking steps that it believes are reasonably designed to
address the Year 2000 Problem with respect to computer systems that it uses and
to obtain reasonable assurances that comparable steps are being taken by the
Trust's other major service providers. At this time, there can be no assurances
that these steps will be sufficient to avoid any adverse impact to the Trust. In
addition, the Year 2000 Problem may adversely affect the markets and the issuers
of securities in which the Trust may invest that, in turn, may adversely affect
the net asset value of the Trust. Improperly functioning trading systems may
result in settlement problems and liquidity issues. In addition, corporate and
governmental data processing errors may result in production problems for
individual companies or issuers and overall economic uncertainty. Earnings of
individual issuers will be affected by remediation costs, which may be
substantial and may be reported inconsistently in U.S. and foreign financial
statements. Accordingly, the Trust's investments may be adversely affected. The
statements above are subject to the Year 2000 Information and Readiness
Disclosure Act, which may limit the legal rights regarding the use of such
statements in the case of dispute.
