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 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. 1 Trust Report FOR THE 12-MONTH PERIOD ENDED OCTOBER 31, 2005 Van Kampen Municipal Opportunity Trust is managed by the Adviser's Municipal Fixed Income team.(1) Current members include Dennis Pietrzak, Executive Director; Robert Wimmel, Vice President; and John Reynoldson, Executive Director. MARKET CONDITIONS During the 12-month period ended October 31, 2005, the economy grew at a good pace, with reasonable gains in employment and sustained strength in consumer spending. Although oil prices soared, core inflation (which excludes food and energy) remained relatively benign. Continuing with the course it began in June of 2004, the Federal Open Market Committee (the Fed) raised the federal funds target rate eight times during the period. Through a "measured pace" of 25 basis point increments, the Fed brought the rate to 3.75 percent at the end of the reporting period. While the yields of short- and intermediate-term bonds moved upward in concert with the Fed's actions, the yields of long-term bonds ended the period virtually unchanged. As a result, the yield curve (which charts the difference between short-term and long-term rates) flattened. Against this backdrop, total returns across the municipal bond market varied dramatically, with long maturity bonds outperforming short-term issues by a wide margin. As investors sought income in an environment of historically low rates, BBB rated and non-rated bonds significantly outperformed high grade debt, and credit spreads tightened markedly. Strong and steady flows of new cash into high yield municipal funds added to the demand for lower rated issues. Sectors with a preponderance of lower rated credits performed with particular strength. Tobacco revenue bonds were by far the best performing sector, supported by overall spread tightening as well as by increasing investor confidence regarding the extent of tobacco companies' future litigation risk. Health care bonds (hospitals and long-term care facilities) also fared well, boosted by strong investor demand. Municipal bond issuance remained robust in 2005, with $336 billion of debt brought to market in the first 10 months of the year, a pace on track to beat the record issuance of 2003. Refunding activity represented a good portion of this activity, as issuers sought to refinance higher cost debt at low prevailing interest rates. Bonds backed by insurance dominated issuance and increased their market penetration to nearly 60 percent. (1)Team members may change without notice from time to time. 2 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 an NAV basis, the trust outperformed its benchmark index, the Lehman Brothers Municipal Bond Index. On a market price basis, the trust underperformed its benchmark. TOTAL RETURNS FOR THE 12-MONTH PERIOD ENDED OCTOBER 31, 2005 ---------------------------------------------------------- BASED ON BASED ON LEHMAN BROTHERS NAV MARKET PRICE MUNICIPAL BOND INDEX 4.17% 0.55% 2.54% ---------------------------------------------------------- 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. Throughout the period, we followed our long-standing practice of trading between liquid, high quality securities which our analysis identified as compelling total return opportunities. Our strategy involves buying these bonds when we believe they are attractively valued, and selling them when they reach our return targets. We then invest the proceeds into bonds with greater potential for future total return. The trust uses leverage to enhance its dividend to common shareholders. The trust borrows money at short-term rates through the issuance of preferred shares. The proceeds are reinvested in longer-term securities, taking advantage of the difference between short- and longer-term rates. The Fed's policy of raising interest rates throughout the period made the trust's borrowing activity more expensive, thereby tempering its benefits. We sought to position the trust for rising rates, a strategy which proved beneficial during the period. To limit the trust's exposure to bonds that would be most vulnerable to rising short-term rates, we sold shorter-term bonds. Pre- refunded issues also figured prominently among our sales. As refinancing activity surged, we sold many bonds which had appreciated significantly during the time the trust had held them. We re-deployed these assets, as well as proceeds from bonds that had been called, into the 20- to 40-year segment of the market. We generally favored bonds with premium (above-market) coupons and more defensive interest rate characteristics. As the yield curve continued to flatten, these longer-maturity bonds contributed strong performance. Additionally, we kept the overall duration of the trust defensively positioned. (Duration is a measure of interest rate sensitivity.) 3 At the end of the period, bonds rated AA or higher accounted for 76 percent of holdings. Within the context of our quality focused approach, we sought opportunities to enhance the trust's yield. For example, after thorough research, we initiated a stake in long-term investment-grade tobacco revenue bonds. Overall, we increased the trust's exposure to BBB rated securities by 7 percentage points to nearly 10 percent at the end of the period. Meanwhile, exposure to AAA rated securities declined from 80 percent to 70 percent at the end of the reporting period. The trust remained well diversified across the major sectors of the municipal market. At the close of the period, the largest sector representations were hospital, airport, wholesale electric, general purpose and higher education. There is no guarantee that any sectors mentioned will continue to perform well or that securities in such sectors will be held by the Trust in the future. CHANGES IN INVESTMENT POLICIES A derivative financial instrument in very general terms refers to a security whose value is "derived" from the value of an underlying asset, reference rate or index. The Trust recently approved a change in its investment policies to allow the Trust to invest up to 15% of its net assets in "inverse floating rate obligations." Floating rate obligations bear rates of interest that are adjusted periodically to reflect changes in market rates of interest. Inverse floating rate obligations have rates that vary inversely with changes in market rates of interest. These securities have varying degrees of liquidity and the market value of such securities generally will fluctuate in response to changes in market rates of interest to a greater extent than the value of an equal principal amount of a fixed rate security having similar credit quality, redemption provisions and maturity. 4 RATINGS ALLOCATION AS OF 10/31/05 AAA/Aaa 69.9% AA/Aa 6.0 A/A 12.6 BBB/Baa 9.8 B/B 0.4 NR 1.3 ----- 100.0% TOP 5 SECTORS AS OF 10/31/05 Hospital 16.2% Airport 13.2 Wholesale Electric 13.1 General Purpose 10.3 Higher Education 6.6 SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 10/31/05 California 14.8% Texas 11.7 New Jersey 9.6 New York 8.5 Washington 5.7 North Carolina 4.9 Pennsylvania 4.4 Massachusetts 3.6 Nevada 3.1 Georgia 2.6 Indiana 2.2 Illinois 2.0 West Virginia 2.0 Michigan 1.9 Florida 1.8 Missouri 1.7 Colorado 1.7 Oklahoma 1.7 Connecticut 1.4 Ohio 1.3 South Carolina 1.3 District of Columbia 1.3 Louisiana 1.2 Maryland 1.2 Alabama 1.2 Arizona 1.0 Kentucky 0.9 Minnesota 0.8 Oregon 0.7 Vermont 0.6 Tennessee 0.6 Iowa 0.5 Virginia 0.5 Wisconsin 0.4 South Dakota 0.4 (continued on next page) 5 SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 10/31/05 (continued from previous page) Puerto Rico 0.3 Mississippi 0.2 New Hampshire 0.2 North Dakota 0.1 ----- Total Investments 100.0% Subject to change daily.

On May 25, 2005, the Board of Trustees, and the independent trustees voting separately, determined that the terms of the investment advisory agreement are fair and reasonable and approved the continuance of the investment advisory contract 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 contract 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 change in the advisory fee rate effective November 1, 2004 and materials it had received in approving a reorganization of the Fund. The Board of Trustees considered the contract over a period of several months and the non-management trustees held sessions both with the investment adviser and separate from the investment adviser in reviewing and considering the contract. 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 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 9 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 contract. 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 contract. 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 a special ad hoc committee of the Board. The trustees discuss with the investment adviser its revenues and expenses, including among other things, revenues for advisory services, portfolio management-related expenses, revenue sharing arrangement 10 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 contract. 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 contract. 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 contract. 11 VAN KAMPEN MUNICIPAL

See Notes to Financial Statements 25 VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2005 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, 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 bid and asked prices or, in the absence of market quotations, at fair value based upon yield data relating to municipal bonds with similar characteristics and general market conditions. Securities which are not valued by independent pricing services or dealers are valued at fair value using procedures established in good faith by the Board of Trustees. Futures contracts are valued at the settlement price established each day on the exchange on which they are traded. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis. 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, 2005, the Trust had $2,488,350 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. During the current fiscal year, the Trust utilized capital losses carried forward of $694,750. 26 VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2005 continued At October 31, 2005, the cost and related gross unrealized appreciation and depreciation are as follows: Cost of investments for tax purposes........................ $380,230,096 ============ Gross tax unrealized appreciation........................... $ 21,290,561 Gross tax unrealized depreciation........................... (1,590,255) ------------ Net tax unrealized appreciation on investments.............. $ 19,700,306 ============ 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. The tax character of distributions paid during the years ended October 31, 2005 and 2004 was as follows: DISTRIBUTIONS PAID FROM: 2005 2004 Ordinary income............................................. $371 $1,281,469 Long-term capital gain...................................... -0- 3,842,711 ---- ---------- $371 $5,124,180 ==== ========== Due to inherent differences in the recognition of income, expenses and realized gains/ losses under accounting principles generally accepted in the United States of America and federal income tax purposes, permanent differences between financial and tax basis reporting for the 2005 fiscal year have been identified and appropriately reclassified. A permanent difference of $23 relating to book to tax accretion differences was reclassified from accumulated undistributed net investment income to accumulated net realized gain. As of October 31, 2005, the components of distributable earnings on a tax basis were as follows: Undistributed ordinary income............................... $ 477,111 Undistributed long-term capital gain........................ 6,136,620 Net realized gains or losses may differ for financial reporting and tax purposes primarily as a result of the deferral of losses relating to wash sale transactions and gains or losses recognized for tax purposes on open futures transactions on October 31, 2005. 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 of the Trust. Effective November 1, 2004, the investment advisory fee was reduced from .60% to .55%. For the year ended October 31, 2005, the Trust recognized expenses of approximately $32,100 representing legal services provided by Skadden, Arps, Slate, Meagher & Flom LLP, 27 VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2005 continued of which a trustee of the Trust is a partner of such firm and he and his law firm provide legal services as legal counsel to the Trust. Under separate Legal Services, Accounting Services and Chief Compliance Officer ("CCO") Employment agreements, the Adviser provides accounting and legal services and the CCO provides compliance services to the Trust. The costs of these services are allocated to each trust. For the year ended October 31, 2005, the Trust recognized expenses of approximately $70,900 representing Van Kampen Investment 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 "Legal" expenses on the Statement of Operations. Services provided pursuant to the Accounting Services and CCO Employment agreement are reported as part of "Other" expenses on the Statement of Operations. Certain officers and trustees of the Trust are also officers and directors of Van Kampen. The Trust does not compensate its officers or trustees who are also officers of Van Kampen. The Trust provides deferred compensation and retirement plans for its trustees who are not officers of Van Kampen. Under the deferred compensation plan, trustees may elect to defer all or a portion of their compensation to a later date. Benefits under the retirement plan are payable upon retirement for a ten-year period and are based upon each trustee's years of service to the Trust. The maximum annual benefit per trustee under the plan is $2,500. 3. CAPITAL TRANSACTIONS At October 31, 2005 and 2004, paid in surplus related to common shares aggregated $226,763,756 and $226,763,756, respectively. Transactions in common shares were as follows: YEAR ENDED YEAR ENDED OCTOBER 31, 2005 OCTOBER 31, 2004 Beginning Shares........................................ 15,357,684 15,352,891 Shares Issued Through Dividend Reinvestment............. -0- 4,793 ---------- ---------- Ending Shares........................................... 15,357,684 15,357,684 ========== ========== 4. INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from sales of investments, excluding short-term investments, were $133,067,817 and $131,062,563, 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 and 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 28 VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2005 continued portfolio holdings, including derivative instruments, are marked to market each day with the change in value reflected in the unrealized appreciation/depreciation. Upon disposition, a realized gain or loss is recognized accordingly, except when taking delivery of a security underlying a futures contract. In this instance, the recognition of gain or loss is postponed until the disposal of the security underlying the futures contract. Risks may arise as a result of the potential inability of the counter parties to meet the terms of their contracts. During the period, the Trust invested in futures contracts, a type of derivative. A futures contract is an agreement involving the delivery of a particular asset on a specified future date at an agreed upon price. The Trust generally invests in exchange traded futures contracts on U.S. Treasury Bonds and Notes and typically closes the contract prior to the delivery date. These contracts are generally used to manage the Trust's effective maturity and duration. Upon entering into futures contracts, the Trust maintains an amount of cash or liquid securities with a value equal to a percentage of the contract amount with either a future commission merchant pursuant to rules and regulations promulgated under the 1940 Act, as amended, or with its custodian in an account in the broker's name. This amount is known as initial margin. During the period the futures contract is open, payments are received from or made to the broker based upon changes in the value of the contract (the variation margin). The risk of loss associated with a futures contract is in excess of the variation margin reflected on the Statement of Assets and Liabilities. Transactions in futures contracts for the year ended October 31, 2005, were as follows: CONTRACTS Outstanding at October 31, 2004............................. 601 Futures Opened.............................................. 3,681 Futures Closed.............................................. (3,055) ------ Outstanding at October 31, 2005............................. 1,227 ====== 6. PREFERRED SHARES The Trust has outstanding 6,000 Auction Preferred Shares ("APS") in two series of 3,000 shares each. 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, 2005 was 2.675%. During the year ended October 31, 2005, the rates ranged from 1.550% to 2.850%. The Trust pays annual fees equivalent to .25% of the preferred share liquidation value for the remarketing efforts associated with the preferred auctions. These fees are included as a component of "Preferred Share Maintenance" expense on the Statement of Operations. The APS are redeemable at the option of the Trust in whole or in part at the liquidation value of $25,000 per share plus accumulated and unpaid dividends. The Trust is subject to certain asset coverage tests and the APS are subject to mandatory redemption if the tests are not met. 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. 29 VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST NOTES TO FINANCIAL STATEMENTS -- OCTOBER 31, 2005 continued 8. TRUST MERGER On June 30, 2005, the Trustees of Van Kampen Advantage Municipal Income Trust ("Target Trust") announced its intention to merge the Target Trust into Van Kampen Municipal Opportunity Trust ("Acquiring Trust"). The Trustees of each of the trusts have approved in principal an agreement and plan of reorganization between the trusts providing for a transfer of assets and liabilities of the Target Trust to the Acquiring Trust in exchange for shares of beneficial interest of the Acquiring Trust (the "Reorganization"). The Reorganization is subject to approval by the shareholders of the Target Trust. The issuance of additional common shares is subject to the approval of the Acquiring Trust. 30 VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST 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, 2005, the related statement of operations 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, 2005, by correspondence with the Trust's 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, 2005, the results of its operations 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. DELOITTE & TOUCHE LLP Chicago, Illinois December 20, 2005 31 VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST 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, EquiServe Trust Company, N.A., 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 32 VAN KAMPEN MUNICIPAL OPPORTUNITY TRUST DIVIDEND REINVESTMENT PLAN continued 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 EquiServe Trust Company, N.A., c/o Computershare Investor Services, P.O. Box 43010, Providence, Rhode Island 02940-3010. 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: Van Kampen Funds Inc.

(e)(1) The audit committee's pre-approval policies and procedures are as follows: 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.
