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, 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 advisor 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 12-MONTH PERIOD ENDED OCTOBER 31, 2007

MARKET CONDITIONS

Strong fundamental and technical factors supported the municipal bond market
throughout the first eight months of the reporting year, helping it to perform
well. In July, however, contagion from the troubled subprime mortgage sector led
to an increasingly illiquid and volatile market, and a flight to quality that
led Treasury bonds to outperform all other sectors of the fixed income market,
including both investment grade and below investment grade municipal bonds.

Up until that time, demand for municipal bonds had been quite strong as
institutional investors and non-traditional buyers such as hedge funds and
arbitrage investors continued to flock to the market. As market liquidity began
to dry up, however, institutional demand fell off and refunding activity, which
had been robust, virtually halted. The decrease in demand put significant
pressure on prices and credit spreads widened, with the most significant
widening occurring in the lower-rated segments of the market.

In mid-September, following the 50 basis point reduction in the target federal
funds rate by the Federal Open Market Committee (the "Fed"), the market began to
stabilize, liquidity improved, and municipal credit spreads began to tighten
again. These positive trends continued through the end of October, when the Fed
reduced rates again, this time by 25 basis points, bringing the target federal
funds rate to 4.5 percent. Although the performance of the municipal market
improved over the last two months of the period, it had not fully recovered as
of period end. Municipal bond issuance remained firm, despite a slowdown in the
summer months, and demand picked up again late in the period as the relative
cheapness of municipal bonds versus Treasuries attracted buyers.

Overall, municipal bond yields ended the period higher, but most of the yield
increases occurred in the intermediate to long maturity portion of the yield
curve, while yields on the front end of the curve declined. As a result, the
municipal yield curve steepened over the course of the period, with the
differential between two-year and 30-year maturities widening to about 100 basis
points.

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.

Various strategies drove the Trust's performance over the course of the
reporting period, most of which focused on seeking to enhance the Trust's yield.
Given the relatively flat shape of the yield cure during most of the period, we
favored bonds with maturities of 25 years or more for their more attractive
yields. This strategy was beneficial early in the period, but hindered overall
performance as Fed easing late in the period pushed short-term rates lower,
causing the short end of the curve to considerably outperform the long end.

We also added to positions in the lower-rated, higher-yielding segment of the
market, primarily BBB and non-rated credits in the health care and tobacco
sectors. These securities were additive to performance for much of the period as
lower-rated bonds outperformed higher-quality issues, but in the last few months
the performance of the lower-rated segment of the market suffered due to
significant spread widening. As a result, the Trust's holdings in both the
health care and tobacco sectors hindered performance for the overall period.
Tobacco bonds were particularly hard hit. Although the fundamental credit
quality of tobacco bonds remained solid throughout the period, the combination
of an abundant supply, the liquidity squeeze in the market, and the flight to
quality caused spreads in the sector to widen dramatically. Additionally, during
the course of the period, a large amount of older tobacco bonds were
pre-refunded but the Trust was not able to benefit from these refundings as it
held primarily new tobacco bonds.

                                                                               3


In an effort to further enhance yield, we increased the portfolio's stake in
inverse floating-rate securities.* Inverse floating-rate securities are, by
nature, highly sensitive to interest rate changes and the Trust's holdings in
these securities held back returns as rates generally rose during the period. We
also increased the Trust's allocation to higher-rated housing bonds. Housing
bond prices declined during the period due to ongoing supply and spread widening
in the sector, which led the Trust's holdings there to dampen performance.
Holdings in transportation bonds also hindered performance.

To help manage interest-rate risk, we implemented a hedge through a short
position in U.S. Treasury futures. This proved to be an effective hedging
strategy, but it dampened returns slightly as the flight to quality in the
summer months drove Treasury prices up and rates lower.

Positive contributors to performance for the fiscal year included holdings in
education, utility, and industrial development revenue/pollution control revenue
bonds. Strong security selection helped holdings in each of these sectors to
outperform those of the benchmark Lehman Brothers Municipal Bond Index.
Additionally, strong security selection in tax-supported debt helped to mitigate
the negative effect of an underweight to this sector, which performed well
during the reporting period.

The Trust remained well diversified across a broad range of municipal market
sectors. As of the end of the reporting period, health care, public power, and
industrial development revenue/pollution control revenue bonds represented the
portfolio's largest sector weightings.

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.

* 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.

CHANGES IN INVESTMENT POLICIES

       The Board of Trustees of the Trust recently approved a non-fundamental
       investment policy for the Trust allowing it to invest up to 20 percent of
       its assets in unrated securities that have been determined by Van Kampen
       Asset Management (the "Adviser") to be of comparable quality to those
       rated investment grade. This is in addition to the Trust's current non-
       fundamental policy allowing it to invest up to 20 percent of its assets
       in unrated securities that have been determined by the Adviser to be of
       comparable quality to those rated below investment grade (BB/Ba or B by
       Standard & Poor's, Moody's Investor Services, Inc. or Fitch Ratings,
       Inc.)

       Unrated securities may be less liquid than rated securities. This may
       have the effect of limiting the ability of the Trust to sell such
       securities at their fair value in response to changes in the economy or
       the financial markets.

PORTFOLIO MANAGEMENT CHANGES

       Van Kampen Municipal Opportunity Trust is managed by the Adviser's
       Municipal Fixed Income team. Current members include William Black,
       Executive Director; Mark Paris, Executive Director; Robert W. Wimmel,
       Executive Director; and Wayne D. Godlin; Managing Director.

Investment Advisory Agreement Approval

Both the Investment Company Act of 1940 and the terms of the Fund's investment
advisory agreement require that the investment advisory agreement between the
Fund and its investment adviser be approved annually both by a majority of the
Board of Trustees and by a majority of the independent trustees voting
separately.

At meetings held on April 17, 2007 and May 30, 2007, the Board of Trustees, and
the independent trustees voting separately, considered and ultimately determined
that the terms of the investment advisory agreement are fair and reasonable and
approved the continuance of the investment advisory agreement as being in the
best interests of the Fund and its shareholders. In making its determination,
the Board of Trustees considered materials that were specifically prepared by
the investment adviser at the request of the Board and Fund counsel, and by an
independent provider of investment company data contracted to assist the Board,
relating to the investment advisory agreement review process. The Board also
considered information received periodically about the portfolio, performance,
the investment strategy, portfolio management team and fees and expenses of the
Fund. Finally, the Board considered materials it had received in approving a
reorganization of the Fund, materials it had received in connection with fee
waivers currently in place for the Fund and materials it had received in
connection with the share repurchase program currently in place for the Fund.
The Board of Trustees considered the investment advisory agreement over a period
of several months and the trustees held sessions both with the investment
adviser and separate from the investment adviser in reviewing and considering
the investment advisory agreement.

In approving the investment advisory agreement, the Board of Trustees
considered, among other things, the nature, extent and quality of the services
provided by the investment adviser, the performance, fees and expenses of the
Fund compared to other similar funds and other products, the investment
adviser's expenses in providing the services and the profitability of the
investment adviser and its affiliated companies. The Board of Trustees
considered the extent to which any economies of scale experienced by the
investment adviser are shared with the Fund's shareholders, and the propriety of
breakpoints in the Fund's investment advisory fee schedule. The Board of
Trustees considered comparative advisory fees of the Fund and other investment
companies and/or other products at different asset levels, and considered the
trends in the industry. The Board of Trustees evaluated other benefits the
investment adviser and its affiliates derive from their relationship with the
Fund. The Board of Trustees reviewed information about the foregoing factors and
considered changes, if any, in such information since its previous approval. The
Board of Trustees discussed the financial strength of the investment adviser and
its affiliated companies and the capability of the personnel of the investment
adviser, and specifically the strength and background of its portfolio
management personnel. The Board of Trustees reviewed the statutory and

                                                                               9


regulatory requirements for approval and disclosure of investment advisory
agreements. The Board of Trustees, including the independent trustees, evaluated
all of the foregoing and does not believe any single factor or group of factors
control or dominate the review process, and, after considering all factors
together, has determined, in the exercise of its business judgment, that
approval of the investment advisory agreement is in the best interests of the
Fund and its shareholders. The following summary provides more detail on certain
matters considered but does not detail all matters considered.

Nature, Extent and Quality of the Services Provided. On a regular basis, the
Board of Trustees considers the roles and responsibilities of the investment
adviser as a whole and for those specific portfolio management, support and
trading functions servicing the Fund. The trustees discuss with the investment
adviser the resources available and used in managing the Fund. The trustees also
discuss certain other services which are provided on a cost-reimbursement basis
by the investment adviser or its affiliates to the Van Kampen funds including
certain accounting, administrative and legal services. The Board has determined
that the nature, extent and quality of the services provided by the investment
adviser support its decision to approve the investment advisory agreement.

Performance, Fees and Expenses of the Fund. On a regular basis, the Board of
Trustees reviews the performance, fees and expenses of the Fund compared to its
peers and to appropriate benchmarks. In addition, the Board spends more focused
time on the performance of the Fund and other funds in the Van Kampen complex,
paying specific attention to underperforming funds. The trustees discuss with
the investment adviser the performance goals and the actual results achieved in
managing the Fund. When considering a fund's performance, the trustees and the
investment adviser place emphasis on trends and longer-term returns (focusing on
one-year, three-year and five-year performance with special attention to
three-year performance) and, when a fund's weighted performance is under the
fund's benchmark, they discuss the causes and where necessary seek to make
specific changes to investment strategy or investment personnel. The Fund
discloses more information about its performance elsewhere in this report. The
trustees discuss with the investment adviser the level of advisory fees for this
Fund relative to comparable funds and other products advised by the adviser and
others in the marketplace. The trustees review not only the advisory fees but
other fees and expenses (whether paid to the adviser, its affiliates or others)
and the Fund's overall expense ratio. The Board has determined that the
performance, fees and expenses of the Fund support its decision to approve the
investment advisory agreement.

Investment Adviser's Expenses in Providing the Service and Profitability. At
least annually, the trustees review the investment adviser's expenses in
providing services to the Fund and other funds advised by the investment adviser
and the profitability of the investment adviser. These profitability reports are
put together by the investment adviser with the oversight of the Board. The
trustees

 10


discuss with the investment adviser its revenues and expenses, including among
other things, revenues for advisory services, portfolio management-related
expenses, revenue sharing arrangement costs and allocated expenses both on an
aggregate basis and per fund. The Board has determined that the analysis of the
investment adviser's expenses and profitability support its decision to approve
the investment advisory agreement.

Economies of Scale. On a regular basis, the Board of Trustees considers the size
of the Fund and how that relates to the Fund's expense ratio and particularly
the Fund's advisory fee rate. In conjunction with its review of the investment
adviser's profitability, the trustees discuss with the investment adviser how
more (or less) assets can affect the efficiency or effectiveness of managing the
Fund's portfolio and whether the advisory fee level is appropriate relative to
current asset levels and/or whether the advisory fee structure reflects
economies of scale as asset levels change. The Board has determined that its
review of the actual and potential economies of scale of the Fund support its
decision to approve the investment advisory agreement.

Other Benefits of the Relationship. On a regular basis, the Board of Trustees
considers other benefits to the investment adviser and its affiliates derived
from its relationship with the Fund and other funds advised by the investment
adviser. These benefits include, among other things, fees for transfer agency
services provided to the funds, in certain cases research received by the
adviser generated from commission dollars spent on funds' portfolio trading, and
in certain cases distribution or service related fees related to funds' sales.
The trustees review with the investment adviser each of these arrangements and
the reasonableness of its costs relative to the services performed. The Board
has determined that the other benefits received by the investment adviser or its
affiliates support its decision to approve the investment advisory agreement.

                                                                              11

VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST

NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2007

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Municipal Opportunity Trust (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 provide a high level of current income exempt from federal
income tax, consistent with preservation of capital. The Trust commenced
investment operations on April 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. 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 October 31, 2007, the Trust had $7,441,712 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 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.

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 and a portion of futures, which are included as
ordinary income for tax purposes.

    The tax character of distributions paid during the years ended October 31,
2007 and 2006 was as follows:



                                                                 2007           2006
                                                                       
Distributions paid from:
  Ordinary income...........................................  $     1,380    $   478,073
  Tax exempt income.........................................   39,305,813     32,610,353
  Long-term capital gain....................................          -0-      6,136,619

                                                              $39,307,193    $39,225,045
                                                              ===========    ===========


    Permanent differences, primarily due to non-deductible costs, resulted in
the following reclassification among the Trust's components of net assets at
October 31, 2007:



     ACCUMULATED
  UNDISTRIBUTED NET   ACCUMULATED NET REALIZED
  INVESTMENT INCOME             LOSS             PAID IN SURPLUS
                                           
       $55,812                 $1,062               $(56,874)


    As of October 31, 2007, the components of distributable earnings on a tax
basis were as follows:

                                                                              35


VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST

NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2007 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, the deferral of losses relating to wash sale
transactions and gains or losses recognized for tax purposes on open futures
transactions on October 31, 2007.

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 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 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
investments 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 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 October 31, 2007, Trust investments with a value of $195,974,260 are
held by the dealer trusts and serve as collateral for the $145,423,000 in
floating rate notes outstanding at that date. Contractual maturities of the
floating rate notes and interest rates in effect at October 31, 2007 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 year ended October 31, 2007 were $132,272,000 and
4.16%, respectively.

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. Effective December 1, 2006, the Adviser
has agreed to waive investment advisory fees equal to .10% of the average daily
net assets including preferred shares of the Trust. For the year ended October
31, 2007, the Adviser waived $814,532 of its advisory fees. This waiver is
voluntary and can be discounted at any time.

    For the year ended October 31, 2007, the Trust recognized expenses of
approximately $61,600 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.

VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST

NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2007 continued

    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 year ended October 31, 2007,
the Trust recognized expenses of approximately $96,000 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.

*   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 period ended
    October 31, 2007, the Trust repurchased 215,300 of its shares at an average
    discount of 6.59% 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.

    On January 27, 2006 the Trust acquired all of the assets and liabilities of
the Van Kampen Advantage Municipal Income Trust (ticker symbol VKA) through a
tax free reorganization approved by VKA's shareholders on January 11, 2006. The
Trust issued 18,814,853 common shares with a net asset value of $306,870,227 and
7,600 Auction Preferred Shares (APS) with a liquidation value of $190,000,000 in
exchange for VKA's net assets. The shares of VKA were converted into Trust
shares at a ratio of 0.984721 to 1 and 1 to 1, for common shares and APS,
respectively. Net unrealized appreciation of VKA as of January 27, 2006 was
$26,207,937. The Trust assumed VKA's book to tax accretion difference, which
resulted in a $652,090 increase to accumulated undistributed net investment
income

                                                                              37

and a corresponding decrease to net unrealized appreciation. Combined net assets
applicable to common shares on the day of the reorganization were $557,410,249
and combined net assets including preferred shares were $897,410,249. Included
in these net assets was a capital loss carryforward of $577,984, gains or losses
of $287,664 recognized for tax purposes on open futures transactions at January
27, 2006, and deferred losses relating to wash sales transactions of $84,376
which are included with accumulated net realized loss of which all can be
utilized by the acquiring Trust. Additionally, included in these net assets was
a deferred compensation and retirement plan balance of $357,767 which is
included with accumulated undistributed net investment income.

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $298,091,397 and $230,393,490,
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 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 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.

VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST

NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2007 continued

    Transactions in futures contracts for the year ended October 31, 2007 were
as follows:



                                                                CONTRACTS
                                                             
Outstanding at October 31, 2006.............................        826
Futures Opened..............................................      5,941
Futures Closed..............................................     (5,877)
                                                                 ------
Outstanding at October 31, 2007.............................        890
                                                                 ======


B. INVERSE FLOATING RATE SECURITIES An inverse floating rate security is one
where the coupon is inversely indexed to a short-term floating interest rate
multiplied by a specific factor. As the floating rate rises, the coupon is
reduced. Conversely, as the floating rate declines, the coupon is increased. The
price of these securities may be more volatile than the price of a comparable
fixed rate security. These instruments are typically used by the Trust to
enhance the yield of the portfolio. These instruments are identified in the
Portfolio of Investments.

C. 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 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
is shown on the Statement of Assets and Liabilities. Risks may arise as a result
of the potential inability of the counterparties to meet the terms of their
contracts. If there is a default by the counterparty, the Trust will have
contractual remedies pursuant to the agreements related to the transaction.

                                                                              39


VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST

NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2007 continued

6. PREFERRED SHARES

The Trust has outstanding 13,600 APS. Series A and B contain 3,000 shares,
Series C, D and E contain 2,000 shares, and Series F contains 1,600 shares.
Dividends are cumulative and the dividend rate on each series is currently reset
every 28 days through an auction process. The average rate in effect on October
31, 2007 was 3.829%. During the year ended October 31, 2007, the rates ranged
from 3.300% to 4.400%.

    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 in 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.

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 July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes --an
interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting
for income taxes by prescribing the minimum recognition threshold a tax position
must meet before being recognized in the financial statements. FIN 48 is
effective for the fiscal years beginning after December 15, 2006, and is to be
applied to all open tax years as of the effective date. Recent SEC guidance
allows implementing FIN 48 in the trust NAV calculations as late as the trust's
last NAV calculation in the first required financial statement period. As a
result, the Trust will incorporate FIN 48 in its semiannual report on April 30,
2008. The impact of the Trust's financial statements, if any, is currently being
assessed.

    In addition, 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. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Trust's financial statement disclosures.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of Van Kampen Municipal Opportunity
Trust

    We have audited the accompanying statement of assets and liabilities of Van
Kampen Municipal Opportunity Trust (the "Trust"), including the portfolio of
investments, as of October 31, 2007, the related statements of operations and
cash flows for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each of the five years in the period then ended. These financial statements and
financial highlights are the responsibility of the Trust's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

    We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Trust is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. Our audits included consideration
of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Trust's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of October 31, 2007, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audits provide a reasonable basis for
our opinion.

    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of Van
Kampen Municipal Opportunity Trust as of October 31, 2007, the results of its
operations and cash flows for the year then ended, the changes in its net assets
for each of the two years in the period then ended, and the financial highlights
for each of the five years in the period then ended, in conformity with
accounting principles generally accepted in the United States of America.

VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST

DIVIDEND REINVESTMENT PLAN

    The dividend reinvestment plan (the "Plan") offers you a prompt and simple
way to reinvest your dividends and capital gains distributions into additional
shares of the Trust. Under the Plan, the money you earn from dividends and
capital gains distributions will be reinvested automatically in more shares of
the Trust, allowing you to potentially increase your investment over time.

PLAN BENEFITS

- ADD TO YOUR ACCOUNT

    You may increase your shares in the Trust easily and automatically with the
Plan.

- LOW TRANSACTION COSTS

    Shareholders who participate in the Plan are able to buy shares at below-
market prices when the Trust is trading at a premium to its net asset value. In
addition, transaction costs are low because when new shares are issued by the
Trust, there is no brokerage fee, and when shares are bought in blocks on the
open market, the brokerage commission is shared among all participants.

- CONVENIENCE

    You will receive a detailed account statement from Computershare Trust
Company, N.A., which administers the Plan, whenever shares are reinvested for
you. The statement shows your total distributions, date of investment, shares
acquired, and price per share, as well as the total number of shares in your
reinvestment account. You can also access your account via the Internet. To do
this, please go to vankampen.com.

- SAFEKEEPING

    Computershare Trust Company, N.A. will hold the shares it has acquired for
you in safekeeping.

HOW TO PARTICIPATE IN THE PLAN

    If you own shares in your own name, you can participate directly in the
Plan. If your shares are held in "street name"--in the name of your brokerage
firm, bank, or other financial institution--you must instruct that entity to
participate on your behalf. If they are unable to participate on your behalf,
you may request that they reregister your shares in your own name so that you
may enroll in the Plan.

    If you choose to participate in the Plan, your dividends and capital gains
distributions will be promptly reinvested for you, automatically increasing your

shares. If the Trust is trading at a share price that is equal to its net asset
value (NAV), you'll pay that amount for your reinvested shares. However, if the
Trust is trading above or below NAV, the price is determined by one of two ways:

    1. PREMIUM If the Trust is trading at a premium--a market price that is
       higher than its NAV--you'll pay either the NAV or 95 percent of the
       market price, whichever is greater. When the Trust trades at a premium,
       you'll pay less for your reinvested shares than an ordinary investor
       purchasing shares on the stock exchange. Keep in mind, a portion of your
       price reduction may be taxable because you are receiving shares at less
       than market price.

    2. DISCOUNT If the Trust is trading at a discount--a market price that is
       lower than its NAV--you'll pay the market price for your reinvested
       shares.

HOW TO ENROLL

    To enroll in the Plan, please read the Terms and Conditions in the Plan
brochure. You can obtain a copy of the Plan Brochure and enroll in the Plan by
visiting vankampen.com, calling toll-free (800) 341-2929 or notifying us in
writing at Van Kampen Closed End Funds, Computershare Trust Company, N.A., P.O.
Box 43078, Providence, RI 02940-3078. Please include the Trust name and account
number and ensure that all shareholders listed on the account sign these written
instructions. Your participation in the Plan will begin with the next dividend
or capital gains distribution payable after Computershare Trust Company, N.A.
receives your authorization, as long as they receive it before the "record
date," which is generally ten business days before the dividend is paid. If your
authorization arrives after such record date, your participation in the Plan
will begin with the following dividend or distribution.

COSTS OF THE PLAN

    There is no direct charge to you for reinvesting dividends and capital gains
distributions because the Plan's fees are paid by the Trust. However, when
applicable, you will pay your portion of any brokerage commissions incurred when
the new shares are purchased on the open market. These brokerage commissions are
typically less than the standard brokerage charges for individual transactions,
because shares are purchased for all participants in blocks, resulting in lower
commissions for each individual participant. Any brokerage commissions or
service fees are averaged into the purchase price.

TAX IMPLICATIONS

    The automatic reinvestment of dividends and capital gains distributions does
not relieve you of any income tax that may be due on dividends or

                                                                              43

Plan. Participants will receive written notice at least 30 days before the
effective date of any amendment. In the case of termination, Participants will

regulatory authority, such written notice will not be required.

    international executive search firm ("Heidrick"). Heidrick has been (and may
    continue to be) engaged by Morgan Stanley from time to time to perform
    executive searches. Such searches have been unrelated to Van Kampen's or
    Morgan Stanley's asset management businesses and have been done by
    professionals at Heidrick without any involvement by Ms. Heagy. Ethical wall
    procedures exist to ensure that Ms. Heagy will not have any involvement with
    any searches performed by Heidrick for Morgan Stanley. Ms. Heagy does not
    receive any compensation, directly or indirectly, for searches performed by
    Heidrick for Morgan Stanley. Ms. Heagy does own common shares of Heidrick
    (representing less than 1% of Heidrick's outstanding common shares).

Item 3. Audit Committee Financial Expert.

The Trust's Board of Trustees has determined that it has three "audit committee
financial experts" serving on its audit committee, each of whom are
"independent" Trustees : Rod Dammeyer, Jerry Choate and R. Craig Kennedy. Under
applicable securities laws, a person who is determined to be an audit committee

expert. The designation or identification of a person as an audit committee

in the absence of such designation or identification.

                              JOINT AUDIT COMMITTEE
                          AUDIT AND NON-AUDIT SERVICES
                       PRE-APPROVAL POLICY AND PROCEDURES
                                     OF THE
                                VAN KAMPEN FUNDS

              AS ADOPTED JULY 23, 2003 AND AMENDED MAY 26, 2004(1)

1.   STATEMENT OF PRINCIPLES

     The Audit Committee of the Board is required to review and, in its sole
discretion, pre-approve all Covered Services to be provided by the Independent
Auditors to the Fund and Covered Entities in order to assure that services
performed by the Independent Auditors do not impair the auditor's independence
from the Fund.(2)

     The SEC has issued rules specifying the types of services that an
independent auditor may not provide to its audit client, as well as the audit
committee's administration of the engagement of the independent auditor. The
SEC's rules establish two different approaches to pre-approving services, which
the SEC considers to be equally valid. Proposed services either: may be
pre-approved without consideration of specific case-by-case services by the
Audit Committee ("general pre-approval"); or require the specific pre-approval
of the Audit Committee ("specific pre-approval"). The Audit Committee believes
that the combination of these two approaches in this Policy will result in an
effective and efficient procedure to pre-approve services performed by the
Independent Auditors. As set forth in this Policy, unless a type of service has
received general pre-approval, it will require specific pre-approval by the
Audit Committee (or by any member of the Audit Committee to which pre-approval
authority has been delegated) if it is to be provided by the Independent
Auditors. Any proposed services exceeding pre-approved cost levels or budgeted
amounts will also require specific pre-approval by the Audit Committee.

     For both types of pre-approval, the Audit Committee will consider whether
such services are consistent with the SEC's rules on auditor independence. The
Audit Committee will also consider whether the Independent Auditors are best
positioned to provide the most effective and efficient services, for reasons
such as its familiarity with the Fund's business, people, culture, accounting
systems, risk profile and other factors, and whether the service might enhance
the Fund's ability to manage or control risk or improve audit quality. All such
factors will be considered as a whole, and no one factor should necessarily be
determinative.

     The Audit Committee is also mindful of the relationship between fees for
audit and non-audit services in deciding whether to pre-approve any such
services and may determine for each fiscal year, the appropriate ratio between
the total amount of fees for Audit, Audit-related and Tax services for the Fund
(including any Audit-related or Tax service fees for Covered Entities that were
subject to pre-approval), and the total amount of fees for certain permissible
non-audit services classified as All Other services for the Fund (including any
such services for Covered Entities subject to pre-approval).

     The appendices to this Policy describe the Audit, Audit-related, Tax and
All Other services that have the general pre-approval of the Audit Committee.
The term of any general pre-approval is 12 months from the date of pre-approval,
unless the Audit Committee considers and provides a different period and states
otherwise. The Audit Committee will annually review and pre-approve the services
that may be provided by the Independent Auditors without obtaining specific
pre-approval

----------
(1)  This Joint Audit Committee Audit and Non-Audit Services Pre-Approval Policy
     and Procedures (the "Policy"), amended as of the date above, supercedes and
     replaces all prior versions that may have been amended from time to time.

(2)  Terms used in this Policy and not otherwise defined herein shall have the
     meanings as defined in the Joint Audit Committee Charter.



from the Audit Committee. The Audit Committee will add to or subtract from the
list of general pre-approved services from time to time, based on subsequent
determinations.

     The purpose of this Policy is to set forth the policy and procedures by
which the Audit Committee intends to fulfill its responsibilities. It does not
delegate the Audit Committee's responsibilities to pre-approve services
performed by the Independent Auditors to management.

     The Fund's Independent Auditors have reviewed this Policy and believes that
implementation of the Policy will not adversely affect the Independent Auditors'
independence.

2.   DELEGATION

     As provided in the Act and the SEC's rules, the Audit Committee may
delegate either type of pre-approval authority to one or more of its members.
The member to whom such authority is delegated must report, for informational
purposes only, any pre-approval decisions to the Audit Committee at its next
scheduled meeting.

3.   AUDIT SERVICES

     The annual Audit services engagement terms and fees are subject to the
specific pre-approval of the Audit Committee. Audit services include the annual
financial statement audit and other procedures required to be performed by the
Independent Auditors to be able to form an opinion on the Fund's financial
statements. These other procedures include information systems and procedural
reviews and testing performed in order to understand and place reliance on the
systems of internal control, and consultations relating to the audit. The Audit
Committee will monitor the Audit services engagement as necessary, but no less
than on a quarterly basis, and will also approve, if necessary, any changes in
terms, conditions and fees resulting from changes in audit scope, Fund structure
or other items.

     In addition to the annual Audit services engagement approved by the Audit
Committee, the Audit Committee may grant general pre-approval to other Audit
services, which are those services that only the Independent Auditors reasonably
can provide. Other Audit services may include statutory audits and services
associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4,
etc.), periodic reports and other documents filed with the SEC or other
documents issued in connection with securities offerings.

     The Audit Committee has pre-approved the Audit services in Appendix B.1.
All other Audit services not listed in Appendix B.1 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).

4.   AUDIT-RELATED SERVICES

     Audit-related services are assurance and related services that are
reasonably related to the performance of the audit or review of the Fund's
financial statements or, to the extent they are Covered Services, the Covered
Entities' financial statements, or that are traditionally performed by the
Independent Auditors. Because the Audit Committee believes that the provision of
Audit-related services does not impair the independence of the auditor and is
consistent with the SEC's rules on auditor independence, the Audit Committee may
grant general pre-approval to Audit-related services. Audit-related services
include, among others, accounting consultations related to accounting, financial
reporting or disclosure matters not classified as "Audit services"; assistance
with understanding and implementing new accounting and financial reporting
guidance from rulemaking authorities; agreed-upon or expanded audit procedures
related to accounting and/or billing records required to respond to or comply
with financial, accounting or regulatory reporting matters; and assistance with
internal control reporting requirements under Forms N-SAR and/or N-CSR.



     The Audit Committee has pre-approved the Audit-related services in Appendix
B.2. All other Audit-related services not listed in Appendix B.2 must be
specifically pre-approved by the Audit Committee (or by any member of the Audit
Committee to which pre-approval has been delegated).

5.   TAX SERVICES

     The Audit Committee believes that the Independent Auditors can provide Tax
services to the Fund and, to the extent they are Covered Services, the Covered
Entities, such as tax compliance, tax planning and tax advice without impairing
the auditor's independence, and the SEC has stated that the Independent Auditors
may provide such services. Hence, the Audit Committee believes it may grant
general pre-approval to those Tax services that have historically been provided
by the Independent Auditors, that the Audit Committee has reviewed and believes
would not impair the independence of the Independent Auditors, and that are
consistent with the SEC's rules on auditor independence. The Audit Committee
will not permit the retention of the Independent Auditors in connection with a
transaction initially recommended by the Independent Auditors, the sole business
purpose of which may be tax avoidance and the tax treatment of which may not be
supported in the Internal Revenue Code and related regulations. The Audit
Committee will consult with Director of Tax or outside counsel to determine that
the tax planning and reporting positions are consistent with this policy.

     Pursuant to the preceding paragraph, the Audit Committee has pre-approved
the Tax Services in Appendix B.3. All Tax services involving large and complex
transactions not listed in Appendix B.3 must be specifically pre-approved by the
Audit Committee (or by any member of the Audit Committee to which pre-approval
has been delegated), including tax services proposed to be provided by the
Independent Auditors to any executive officer or trustee/director/managing
general partner of the Fund, in his or her individual capacity, where such
services are paid for by the Fund (generally applicable only to internally
managed investment companies).

6.   ALL OTHER SERVICES

     The Audit Committee believes, based on the SEC's rules prohibiting the
Independent Auditors from providing specific non-audit services, that other
types of non-audit services are permitted. Accordingly, the Audit Committee
believes it may grant general pre-approval to those permissible non-audit
services classified as All Other services that it believes are routine and
recurring services, would not impair the independence of the auditor and are
consistent with the SEC's rules on auditor independence.

     The Audit Committee has pre-approved the All Other services in Appendix
B.4. Permissible All Other services not listed in Appendix B.4 must be
specifically pre-approved by the Audit Committee (or by any member of the Audit
Committee to which pre-approval has been delegated).

     A list of the SEC's prohibited non-audit services is attached to this
policy as Appendix B.5. The SEC's rules and relevant guidance should be
consulted to determine the precise definitions of these services and the
applicability of exceptions to certain of the prohibitions.

7.   PRE-APPROVAL FEE LEVELS OR BUDGETED AMOUNTS

     Pre-approval fee levels or budgeted amounts for all services to be provided
by the Independent Auditors will be established annually by the Audit Committee.
Any proposed services exceeding these levels or amounts will require specific
pre-approval by the Audit Committee. The Audit Committee is mindful of the
overall relationship of fees for audit and non-audit services in determining
whether to pre-approve any such services. For each fiscal year, the Audit
Committee may determine the appropriate ratio between the total amount of fees
for Audit, Audit-related, and Tax services for the Fund (including any
Audit-related or Tax services fees for Covered Entities subject to
pre-approval), and the total amount of fees for certain permissible non-audit
services classified as All Other services for the Fund (including any such
services for Covered Entities subject to pre-approval).



8.   PROCEDURES

     All requests or applications for services to be provided by the Independent
Auditors that do not require specific approval by the Audit Committee will be
submitted to the Fund's Chief Financial Officer and must include a detailed
description of the services to be rendered. The Fund's Chief Financial Officer
will determine whether such services are included within the list of services
that have received the general pre-approval of the Audit Committee. The Audit
Committee will be informed on a timely basis of any such services rendered by
the Independent Auditors. Requests or applications to provide services that
require specific approval by the Audit Committee will be submitted to the Audit
Committee by both the Independent Auditors and the Fund's Chief Financial
Officer, and must include a joint statement as to whether, in their view, the
request or application is consistent with the SEC's rules on auditor
independence.

     The Audit Committee has designated the Fund's Chief Financial Officer to
monitor the performance of all services provided by the Independent Auditors and
to determine whether such services are in compliance with this Policy. The
Fund's Chief Financial Officer will report to the Audit Committee on a periodic
basis on the results of its monitoring. A sample report is included as Appendix
B.7. Both the Fund's Chief Financial Officer and management will immediately
report to the chairman of the Audit Committee any breach of this Policy that
comes to the attention of the Fund's Chief Financial Officer or any member of
management.

9.   ADDITIONAL REQUIREMENTS

     The Audit Committee has determined to take additional measures on an annual
basis to meet its responsibility to oversee the work of the Independent Auditors
and to assure the auditor's independence from the Fund, such as reviewing a
formal written statement from the Independent Auditors delineating all
relationships between the Independent Auditors and the Fund, consistent with
Independence Standards Board No. 1, and discussing with the Independent Auditors
its methods and procedures for ensuring independence.

10.  COVERED ENTITIES

     Covered Entities include the Fund's investment adviser(s) and any entity
controlling, controlled by or under common control with the Fund's investment
adviser(s) that provides ongoing services to the Fund(s). Beginning with
non-audit service contracts entered into on or after May 6, 2003, the Fund's
audit committee must pre-approve non-audit services provided not only to the
Fund but also to the Covered Entities if the engagements relate directly to the
operations and financial reporting of the Fund. This list of Covered Entities
would include:

     -    Van Kampen Investments Inc.

     -    Van Kampen Asset Management

     -    Van Kampen Advisors Inc.

     -    Van Kampen Funds Inc.

     -    Van Kampen Investor Services Inc.

     -    Morgan Stanley Investment Management Inc.

     -    Morgan Stanley Trust Company

     -    Morgan Stanley Investment Management Ltd.

     -    Morgan Stanley Investment Management Company

     -    Morgan Stanley Asset & Investment Trust Management Company Ltd.

(e)(2) Beginning with non-audit service contracts entered into on or after May
6, 2003, the audit committee also is required to pre-approve services to Covered
Entities to the extent that the services



are determined to have a direct impact on the operations or financial reporting
of the Registrant. 100% of such services were pre-approved by the audit
committee pursuant to the Audit Committee's pre-approval policies and procedures
(included herein).

(f) Not applicable.

(g) See table above.

(h) The audit committee of the Board of Trustees has considered whether the
provision of services other than audit services performed by the auditors to the
Registrant and Covered Entities is compatible with maintaining the auditors'
independence in performing audit services.

Item 5. Audit Committee of Listed Registrants.

(a) The Trust has a separately-designated standing audit committee established
in accordance with Section 3(a)(58)(A) of the Exchange Act whose members are: R.
Craig Kennedy, Jerry Choate and Rod Dammeyer.

(b) Not applicable.

Item 6. Schedule of Investments.

Please refer to Item #1.

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End
Management Investment Companies.

The Trust invests in exclusively non-voting securities and therefore this item
is not applicable to the Trust.

Item 8. Portfolio Managers of Closed-End Management Investment Companies.

                  VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST (VMO)

                                 FUND MANAGEMENT

PORTFOLIO MANAGEMENT. As of the date of this report, the Fund is managed by
members of the Municipals team. The team consists of portfolio managers and
analysts. Current members of the team jointly and primarily responsible for the
day-to-day management of the Fund's portfolio and the overall execution of the
strategy of the Fund are William Black, an Executive Director of the Adviser,
Mark Paris, an Executive Director of the Adviser, Robert W. Wimmel, an Executive
Director of the Adviser and Wayne D. Godlin, a Managing Director of the Adviser.

Mr. Black has been associated with the Adviser as a High Yield Municipal Analyst
since June 1998 and began managing the Fund in December 2007. Mr. Paris has been
associated with the Adviser as a Municipal Trader since August 2002 and began
managing the Fund in December 2007. Mr. Wimmel has been associated with the
Adviser in an investment management capacity since August 1996 and began
managing the Fund in November 2001. Mr. Godlin has been associated with the
Adviser in an investment management capacity since May 1988 and began managing
the Fund in December 2007.

The composition of the team may change from time to time.

OTHER ACCOUNTS MANAGED BY THE PORTFOLIO MANAGERS

As of October 31, 2007:

Mr. Wimmel managed 15 registered investment companies with a total of
approximately $8.4 billion in assets; no pooled investment vehicles other than
registered investment companies; and no other accounts.



Mr. Godlin managed 5 registered investment companies with a total of
approximately $6.3 billion in assets; no pooled investment vehicles other than
registered investment companies; and no other accounts.

As of December 19, 2007:

Mr. Black managed 12 registered investment companies with a total of
approximately $11.2 billion in assets; no pooled investment vehicles other than
registered investment companies; and no other accounts.

Mr. Paris managed 14 registered investment companies with a total of
approximately $11.4 billion in assets; no pooled investment vehicles other than
registered investment companies; and no other accounts.

Because the portfolio managers manage assets for other investment companies,
pooled investment vehicles, and/or other accounts (including institutional
clients, pension plans and certain high net worth individuals), there may be an
incentive to favor one client over another resulting in conflicts of interest.
For instance, the Adviser may receive fees from certain accounts that are higher
than the fee it receives from the Fund, or it may receive a performance-based
fee on certain accounts. In those instances, the portfolio managers may have an
incentive to favor the higher and/or performance-based fee accounts over the
Fund. The portfolio managers of the Fund do not currently manage accounts for
other investment companies, pooled investment vehicles or other accounts that
charge a performance-based fee. In addition, a conflict of interest could exist
to the extent the Adviser has proprietary investments in certain accounts, where
portfolio managers have personal investments in certain accounts or when certain
accounts are investment options in the Adviser's employee benefits and/or
deferred compensation plans. The portfolio manager may have an incentive to
favor these accounts over others. If the Adviser manages accounts that engage in
short sales of securities of the type in which the Fund invests, the Adviser
could be seen as harming the performance of the Fund for the benefit of the
accounts engaged in short sales if the short sales cause the market value of the
securities to fall. The Adviser has adopted trade allocation and other policies
and procedures that it believes are reasonably designed to address these and
other conflicts of interest.

PORTFOLIO MANAGER COMPENSATION STRUCTURE

Portfolio managers receive a combination of base compensation and discretionary
compensation, comprised of a cash bonus and several deferred compensation
programs described below. The methodology used to determine portfolio manager
compensation is applied across all accounts managed by the portfolio manager.

BASE SALARY COMPENSATION. Generally, portfolio managers receive base salary
compensation based on the level of their position with the Adviser.

DISCRETIONARY COMPENSATION. In addition to base compensation, portfolio managers
may receive discretionary compensation.

Discretionary compensation can include:

-    Cash Bonus;

-    Morgan Stanley's Long-Term Incentive Compensation Program awards -- a
     mandatory program that defers a portion of discretionary year-end
     compensation into restricted stock units or other awards or other
     investments based on Morgan Stanley common stock that are subject to
     vesting and other conditions;

-    Investment Management Alignment Plan (IMAP) awards -- a mandatory program
     that defers a portion of discretionary year-end compensation and notionally
     invests it in designated funds advised by the Adviser or its affiliates.
     The award is subject to vesting and other conditions. Portfolio managers
     must notionally invest a minimum of 25% to a maximum of 100% of the IMAP
     deferral into a combination of the designated open-end funds they manage
     that are included in the IMAP Fund menu;



-    Voluntary Deferred Compensation Plans -- voluntary programs that permit
     certain employees to elect to defer a portion of their discretionary
     year-end compensation and directly or notionally invest the deferred
     amount: (1) across a range of designated investment funds, including funds
     advised by the Adviser or its affiliates; and/or (2) in Morgan Stanley
     stock units.

     Several factors determine discretionary compensation, which can vary by
     portfolio management team and circumstances. In order of relative
     importance, these factors include:

-    Investment performance. A portfolio manager's compensation is linked to the
     pre-tax investment performance of the funds/accounts managed by the
     portfolio manager. Investment performance is calculated for one-, three-
     and five-year periods measured against an appropriate securities market
     index (or indices) for the funds/accounts managed by the portfolio manager.
     The assets managed by the portfolio managers in funds, pooled investment
     vehicles and other accounts are described in "Other Accounts Managed by the
     Portfolio Managers" above. Generally, the greatest weight is placed on the
     three- and five-year periods.

-    Revenues generated by the investment companies, pooled investment vehicles
     and other accounts managed by the portfolio manager.

-    Contribution to the business objectives of the Adviser.

-    The dollar amount of assets managed by the portfolio manager.

-    Market compensation survey research by independent third parties.

-    Other qualitative factors, such as contributions to client objectives.

-    Performance of Morgan Stanley and Morgan Stanley Investment Management
     Inc., and the overall performance of the investment team(s) of which the
     portfolio is a member.

SECURITIES OWNERSHIP OF PORTFOLIO MANAGERS

As of October 31, 2007, the portfolio managers did not own any shares of the
Fund.
