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. 1 Trust Report FOR THE SIX-MONTH PERIOD ENDED APRIL 30, 2007 MARKET CONDITIONS The overall environment for municipal bonds was favorable during the reporting period, but mixed economic indicators and concerns about the residential housing sector led to increased market uncertainty and volatility. At the beginning of the period, the pace of economic growth appeared to be slowing, but in December, the outlook for the economy turned positive following a slate of stronger-than-expected economic releases. The improved economic picture pushed bond yields higher and effectively reversed the run-up in prices that had begun in July on concern over the weak housing market's potential drag on the economy. Bonds continued to decline until February, when the sub-prime mortgage market showed signs of deterioration, causing a sell-off in equities and a flight-to-quality bond market rally. In March, the rally ended as strong employment reports and upward movement in inflationary pressures sparked selling in an overbought Treasury market. At month end, however, the short end of the bond market rebounded strongly following news that the Federal Open Market Committee (the "Fed") had dropped its bias toward higher rates. This came as somewhat of a surprise, given the fact that core inflation readings remained elevated. Municipal bond yields followed the general movement of the Treasury market. However, the 30-year AAA municipal yield reached lows not seen in decades, declining to 4.00 percent in the first half of the reporting period before reversing course and ending the period higher at 4.10 percent. Yields on the short end of the municipal curve rose more than long-term yields during the period. As a result, the short end of the curve posted the lowest returns while the long end outperformed other portions of the curve by as much as 70 basis points. The slope of the municipal curve (which is defined by the traditional yield advantage of bonds with longer maturities) still remained relatively flat and as such, the yield differential between long maturity and short maturity issues was quite small. New issue supply rose dramatically during the period, increasing by 34 percent versus the same six-month period a year ago, as relatively low interest rates spurred municipalities to refinance their debt. Demand for municipal bonds was robust as well, particularly for high-yield securities as investors proved increasingly willing to take on more risk in return for relatively higher yields. The strong demand caused most credit spreads, which were already near historically tight levels, to further narrow. As a result, the lower-quality, higher yielding segment of the market considerably outperformed, returning 182 basis points more than the investment-grade segment for the overall period. 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 underperformed its benchmark index, the Lehman Brothers Municipal Bond Index. On a market price basis, the Trust outperformed its benchmark. TOTAL RETURNS FOR THE SIX-MONTH PERIOD ENDED APRIL 30, 2007 ------------------------------------------------- BASED ON LEHMAN BROTHERS BASED ON MARKET MUNICIPAL NAV PRICE BOND INDEX 1.39% 10.52% 1.59% ------------------------------------------------- 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. A variety of strategies drove the Trust's performance during the course of the period. One of the key drivers was our focus on the long end of the yield curve. Given the relatively flat shape of the curve throughout the period, we invested in bonds with maturities of 25 years or more in order to capture more attractive yields. The emphasis on longer-maturity issues proved beneficial to performance as this segment of the curve outperformed for the overall period. We also focused on the higher-yielding sector of the market, adding to positions in BBB and lower-rated credits. Additionally, in an effort to further enhance the portfolio's yield, we added to holdings of inverse floating-rate securities.* These strategies were additive to the Trust's performance during the first four months of the period. In the last two months, however, spread widening led the performance of lower-rated bonds to wane and rising interest rates hurt the performance of inverse floating-rate securities. As a result, the Trust's holdings in these credits detracted somewhat from performance late in the period. The biggest contributor to the Trust's underperformance versus the Lehman Brothers Municipal Bond Index, however, was its holdings of tobacco revenue bonds. A large amount of older tobacco bonds were pre-refunded during the period. Unlike the Lehman Brothers Municipal Bond Index, which contained these older bonds, the Trust only had positions in newer tobacco bonds which were not pre-refunded. As such, the portfolio was not able to benefit from the refundings that took place during the period, which detracted from the *An inverse floating-rate security, or "inverse floater", is a variable rate security whose coupon rate changes in the opposite direction from the change in the reference rate used to calculate the coupon rate. 3 performance of the Trust's holdings in this sector relative to those of the Lehman Brothers Municipal Bond Index. In addition, spread widening in the sector in the latter months of period also caused these holdings to hinder performance. Because the inverse floating-rate securities effectively added to the portfolio's duration (a measure of interest-rate risk), we hedged that risk by selling U.S. Treasury futures. This strategy was additive to performance for the overall period and served to keep the Trust's duration neutral relative to that of the Lehman Brothers Municipal Bond Index. We also purchased various A and BBB rated health care bonds during the period, which enhanced the Trust's overall performance. An abundant supply of housing bonds created some favorable opportunities to add to the Trust's holdings in this sector as well. Although these holdings did not add to the portfolio's total return during the period, they did serve to enhance the Trust's yield, as did additional purchases of discount coupon bonds. The Trust remained well diversified across a broad spectrum of municipal market sectors. As of the end of the period, hospital, general purpose, and master tobacco settlement 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. 4 RATINGS ALLOCATION AS OF 4/30/07 AAA/Aaa 54.7% AA/Aa 14.2 A/A 10.2 BBB/Baa 12.7 BB/Ba 0.6 B/B 1.0 Non-Rated 6.6 TOP FIVE SECTORS AS OF 4/30/07 Hospital 17.3% General Purpose 9.5 Master Tobacco Settlement 7.9 Single Family 6.0 Airports 5.8 SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 4/30/07 California 19.2% New York 8.7 Illinois 7.9 Florida 6.9 New Jersey 5.7 Texas 4.9 Missouri 3.3 South Carolina 3.2 Colorado 3.1 Alabama 3.0 Pennsylvania 2.6 Ohio 2.2 Washington 2.0 Indiana 2.0 Nevada 1.8 Louisiana 1.8 North Carolina 1.5 Connecticut 1.5 Kentucky 1.4 Michigan 1.4 Arizona 1.3 Georgia 1.3 Virginia 1.3 Massachusetts 1.2 Maryland 1.2 Wisconsin 1.1 Tennessee 0.9 Oklahoma 0.9 Alaska 0.8 Puerto Rico 0.6 New Hampshire 0.6 West Virginia 0.6 Iowa 0.6 Guam 0.5 District of Columbia 0.5 (continued on next page) 5 SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 4/30/07 (continued from previous page) Oregon 0.5 South Dakota 0.5 Kansas 0.4 Minnesota 0.4 Nebraska 0.2 Arkansas 0.2 New Mexico 0.1 North Dakota 0.1 Vermont 0.1 Mississippi 0.0* ----- Total Investments 100.0% *Amount is less than 0.1% Subject to change daily.

SIGNIFICANT ACCOUNTING POLICIES Van Kampen Municipal 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 seek to provide a high level of current income exempt from federal income tax, consistent with preservation of capital. The Trust will invest in a portfolio consisting substantially of municipal obligations rated investment grade at the time of investment, but may invest up to 20% of its assets in unrated securities which are believed to be of comparable quality to those rated investment grade. The Trust commenced investment operations on September 27, 1991. The following is a summary of significant accounting policies consistently followed by the Trust in the preparation of its financial statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A. SECURITY VALUATION Municipal bonds are valued by independent pricing services or dealers using the mean of the last reported bid and asked prices or, in the absence of market quotations, at fair value based upon yield data relating to municipal bonds with similar characteristics and general market conditions. Securities which are not valued by independent pricing services or dealers are valued at fair value using procedures established in good faith by the Board of Trustees. Futures contracts are valued at the settlement price established each day on the exchange on which they are traded. Interest rate swaps are valued using market quotations obtained from brokers. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis. The Trust may purchase and sell securities on a "when-issued" or "delayed delivery" basis, with settlement to occur at a later date. The value of the security so purchased is subject to market fluctuations during this period. The Trust will segregate assets with the custodian having an aggregate value at least equal to the amount of the when-issued or delayed delivery purchase commitments until payment is made. At April 30, 2007, the Trust had $1,000,000 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. 33 VAN KAMPEN MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2007 (UNAUDITED) continued At October 31, 2006, the Trust had an accumulated capital loss carry forward for tax purposes of $4,894,986, which will expire according to the following schedule.

October 31, 2014 A portion of the capital loss carryforward above was acquired due to a merger with another regulated investment company and is subject to annual limitations. At April 30, 2007, the cost and related gross unrealized appreciation and depreciation are as follows: Cost of investments for tax purposes........................ $901,354,848 ============ Gross tax unrealized appreciation........................... $ 50,078,239 Gross tax unrealized depreciation........................... (1,382,663) ------------ Net tax unrealized appreciation on investments.............. $ 48,695,576 ============ E. DISTRIBUTION OF INCOME AND GAINS The Trust declares and pays monthly dividends from net investment income to common shareholders. Net realized gains, if any, are distributed at least annually on a pro rata basis to common and preferred shareholders. Distributions from net realized gains for book purposes may include short-term capital gains and a portion of futures gains, which are included as ordinary income for tax purposes. The tax character of distributions paid during the year ended October 31, 2006 was as follows: Distributions paid from: Ordinary income........................................... $ 243,323 Tax-exempt income......................................... 40,079,119 Long-term capital gain.................................... 11,619,205 ----------- $51,941,647 =========== As of October 31, 2006, the components of distributable earnings on a tax basis were as follows: Undistributed ordinary income............................... $ 2,654 Undistributed tax-exempt income............................. 2,799,305 Undistributed long-term capital gain........................ -0- Net realized gains or losses may differ for financial reporting and tax purposes primarily as a result of gains or losses recognized on securities for tax purposes but not for book purposes. F. FLOATING RATE NOTE OBLIGATIONS RELATED TO SECURITIES HELD The Trust enters into transactions in which it transfers to dealer trusts fixed rate bonds in exchange for cash and 34 VAN KAMPEN MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2007 (UNAUDITED) continued residual interests in the dealer trusts' assets and cash flows, which are in the form of inverse floating rate investments. The dealer trusts fund the purchases of the fixed rate bonds by issuing floating rate notes to third parties and allowing the Trust to retain residual interests in the bonds. The Trust enters into shortfall agreements with the dealer trusts, which commit the Trust to pay the dealer trusts, in certain circumstances, the difference between the liquidation value of the fixed rate bonds held by the dealer trusts and the liquidation value of the floating rate notes held by third parties, as well as any shortfalls in interest cash flows. The residual interests held by the Trust (inverse floating rate investments) include the right of the Trust (1) to cause the holders of the floating rate notes to tender their notes at par at the next interest rate reset date, and (2) to transfer the municipal bond from the dealer trusts to the Trust, thereby collapsing the dealer trusts. The Trust accounts for the transfer of bonds to the dealer trusts as secured borrowings, with the securities transferred remaining in the Trust's investment assets, and the related floating rate notes reflected as Trust liabilities under the caption "Floating Rate Note Obligations" on the Statement of Assets and Liabilities. The Trust records the interest income from the fixed rate bonds under the caption "Interest" and records the expenses related to floating rate note obligations and any administrative expenses of the dealer trusts under the caption "Interest and Residual Trust Expenses" on the Trust's Statement of Operations. The notes issued by the dealer trusts have interest rates that reset weekly and the floating rate note holders have the option to tender their notes to the dealer trusts for redemption at par at each reset date. At April 30, 2007, Trust investments with a value of $279,027,489 are held by the dealer trusts and serve as collateral for the $200,795,000 in floating rate notes outstanding at that date. Contractual maturities of the floating rate notes and interest rates in effect at April 30, 2007 are presented on the Portfolio of Investments. 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. During the period ended April 30, 2007, the Adviser waived $399,440 of its advisory fees. The waiver is voluntary and can be discontinued at any time. For the six months ended April 30, 2007, the Trust recognized expenses of approximately $30,700 representing legal services provided by Skadden, Arps, Slate, Meagher & Flom LLP, of which a trustee of the Trust is a partner of such firm and he and his law firm provide legal services as legal counsel to the Trust. Under separate Legal Services, Accounting Services and Chief Compliance Officer (CCO) Employment agreements, the Adviser provides accounting and legal services and the CCO provides compliance services to the Trust. The costs of these services are allocated to each trust. For the six months ended April 30, 2007, the Trust recognized expenses of approximately $50,800 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 35 VAN KAMPEN MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2007 (UNAUDITED) continued Accounting Services and CCO Employment agreement are reported as part of "Accounting and Administrative Expenses" on the Statement of Operations. Certain officers and trustees of the Trust are also officers and directors of Van Kampen. The Trust does not compensate its officers or trustees who are also officers of Van Kampen. The Trust provides deferred compensation and retirement plans for its trustees who are not officers of Van Kampen. Under the deferred compensation plan, trustees may elect to defer all or a portion of their compensation to a later date. Benefits under the retirement plan are payable upon retirement for a ten-year period and are based upon each trustee's years of service to the Trust. The maximum annual benefit per trustee under the plan is $2,500. 3. CAPITAL TRANSACTIONS For the six months ended April 30, 2007 and the year ended October 31, 2006, transactions in common shares were as follows: SIX MONTHS ENDED YEAR ENDED APRIL 30, 2007 OCTOBER 31, 2006 Beginning Shares........................................ 39,379,538 39,379,538 Shares Repurchased*..................................... -0- -0- ---------- ---------- Ending Shares........................................... 39,379,538 39,379,538 ========== ========== * 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 April 30, 2007, the Trust repurchased none of its shares. The Trust may repurchase its outstanding shares at such time and in such amounts as it believes such activity will further the accomplishment of the foregoing objectives, subject to review of the Trustees. 4. INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from sales of investments, excluding short-term investments, were $177,518,687 and $81,899,025, 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. 36 VAN KAMPEN MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2007 (UNAUDITED) continued Summarized below are the specific types of derivative financial instruments used by the Trust. A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery of a particular asset on a specified future date at an agreed upon price. The Trust generally invests in exchange traded futures contracts on U.S. Treasury securities and typically closes the contract prior to the delivery date. These contracts are generally used to manage the Trust's effective maturity and duration. Upon entering into futures contracts, the Trust maintains an amount of cash or liquid securities with a value equal to a percentage of the contract amount with either a futures commission merchant pursuant to the rules and regulations promulgated under the 1940 Act, as amended, or with its custodian in an account in the broker's name. This amount is known as initial margin. During the period the futures contract is open, payments are received from or made to the broker based upon changes in the value of the contract (the variation margin). The risk of loss associated with a futures contract is in excess of the variation margin reflected on the Statement of Assets and Liabilities. Transactions in futures contracts for the six months ended April 30, 2007 were as follows: CONTRACTS Outstanding at October 31, 2006............................. 727 Futures Opened.............................................. 3,763 Futures Closed.............................................. (3,388) ------ Outstanding at April 30, 2007............................... 1,102 ====== B. INTEREST RATE SWAPS The Trust may enter into forward interest rate swap transactions intended to help the Trust manage its overall interest rate sensitivity, either shorter or longer, generally to more closely align the Trust's interest rate sensitivity with that of the broader municipal market. Forward interest rate swap transactions involve the Trust's agreement with a counterparty to pay, in the future, a fixed or variable rate payment in exchange for the counterparty paying the Trust a variable or fixed rate payment, the accruals for which would begin at a specified date in the future (the "effective date"). The amount of the payment obligation is based on the notional amount of the forward swap contract and the termination date of the swap (which is akin to a bond's maturity). The value of the Trust's swap commitment would increase or decrease based primarily on the extent to which long-term interest rates for bonds having a maturity of the swap's termination date increases or decreases. The Trust may terminate a swap contract prior to the effective date, at which point 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 37 VAN KAMPEN MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2007 (UNAUDITED) continued contract, the Trust has instructed the custodian to pledge cash or liquid securities as collateral with a value approximately equal to the amount of the unrealized loss. Collateral pledges are monitored and subsequently adjusted if and when the swap valuations fluctuate. Restricted cash for segregating purposes, if any, is shown on the Statement of Assets and Liabilities. C. INVERSE FLOATING RATE INVESTMENTS The Trust may invest a portion of its assets in inverse floating rate instruments, either through outright purchases of inverse floating rate securities or through the transfer of bonds to a dealer trust in exchange for cash and residual interests in the dealer trust. These investments are typically used by the Trust in seeking to enhance the yield of the portfolio. These instruments typically involve greater risks than a fixed rate municipal bond. In particular, these instruments are acquired through leverage or may have leverage embedded in them and therefore involve many of the risks associated with leverage. Leverage is a speculative technique that may expose the Trust to greater risk and increased costs. Leverage may cause the Trust's net asset value to be more volatile than if it had not been leveraged because leverage tends to magnify the effect of any increases or decreases in the value of the Trust's portfolio securities. The use of leverage may also cause the Trust to liquidate portfolio positions when it may not be advantageous to do so in order to satisfy its obligations with respect to inverse floating rate instruments. 6. PREFERRED SHARES The Trust has outstanding 13,000 APS. Series A, Series B, Series C and Series D each contain 3,000 shares and Series E contains 1,000 shares. Dividends are cumulative and the dividend rates are generally reset every 7 days for Series A and Series C, while Series B, Series D and Series E are generally reset every 28 days through an auction process. The average rate in effect on April 30, 2007 was 3.765%. During the six months ended April 30, 2007, the rates ranged from 3.240% to 3.950%. 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. 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 38 VAN KAMPEN MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2007 (UNAUDITED) continued 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 semi annual report on April 30, 2008. The impact to 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. 39 VAN KAMPEN MUNICIPAL TRUST DIVIDEND REINVESTMENT PLAN The dividend reinvestment plan offers you a prompt and simple way to reinvest your dividends and capital gains distributions into additional shares of your trust. Under the plan, the money you earn from dividends and capital gains distributions will be reinvested automatically in more shares of your trust, allowing you to potentially increase your investment over time. PLAN BENEFITS - ADD TO YOUR ACCOUNT You may increase your shares in your trust easily and automatically with the dividend reinvestment 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. - SAFEKEEPING Computershare Trust Company, N.A. will hold the shares it has acquired for you in safekeeping, which provides added protection against loss, theft, or inadvertent destruction of certificates. However, you may request that a certificate representing your reinvested shares be issued to you. HOW DOES THE PLAN WORK? 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 your 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 your trust is trading above or below its NAV, the price is determined by one of two ways: 1. PREMIUM If your 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 your 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. 40 VAN KAMPEN MUNICIPAL TRUST DIVIDEND REINVESTMENT PLAN continued 2. DISCOUNT If your 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 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, whenever your trust declares a dividend or capital gains distribution, it will be invested in additional shares of your trust that are purchased on the open market. HOW TO ENROLL To enroll in the Dividend Reinvestment Plan please visit vankampen.com or call (800) 341-2929 or notify us in writing at the address below. Van Kampen Closed-End Funds Computershare Trust Company, N.A. P.O. Box 43011 Providence, RI 02940-3011 Please include your 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 your trust. If your trust is trading at or above its NAV, your new shares are issued directly by the trust and there are no brokerage charges or commissions. However, if your trust is trading at a discount, the shares are purchased on the open market, and you will pay your portion of any brokerage commissions. These brokerage commissions are typically less than the standard brokerage charges for individual transactions because shares are purchased for all participants in 41 VAN KAMPEN MUNICIPAL TRUST DIVIDEND REINVESTMENT PLAN continued 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 distributions. You will receive tax information annually to help you prepare your federal and state income tax returns. HOW TO WITHDRAW FROM THE PLAN To withdraw from the Dividend Reinvestment Plan please visit vankampen.com or call (800) 341-2929 or notify us in writing at the address below. Van Kampen Closed-End Funds Computershare Trust Company, N.A. P.O. Box 43011 Providence, RI 02940-3011 All shareholders listed on the account must sign any written withdrawal instructions. If you withdraw, you have two choices for receiving your shares: - CERTIFICATE We will issue a certificate for the full shares and send you a check for any fractional shares without a charge. - CHECK We will sell all full and fractional shares and send the proceeds to your address of record after deducting brokerage commissions and a $2.50 service fee. The Trust and Computershare Trust Company, N.A. may amend or terminate the plan. Participants will receive written notice at least 30 days before the effective date of any amendment. In the case of termination, participants will receive written notice at least 30 days before the record date for the payment of any dividend or capital gains distribution by your trust.
