TOM BYRON, PORTFOLIO MANAGER, HAS MANAGED THE TRUST SINCE 2000 AND HAS WORKED IN THE INVESTMENT INDUSTRY SINCE 1981. THE FOLLOWING DISCUSSION REFLECTS HIS VIEWS ON THE TRUST'S PERFORMANCE. Q WHAT WAS THE MARKET ENVIRONMENT OF THE PAST SIX MONTHS, AND HOW DID THE TRUST PERFORM IN THAT ENVIRONMENT? A The environment over the past six months has been defined by two major themes. The first of these was the level of interest rates. The period began with interest rates at levels not seen in over three decades and, surprisingly for many, ended with rates slightly lower. The Federal Reserve Board (the Fed) helped keep rates low with a widely anticipated rate cut in November, driven by economic uncertainty and geopolitical risk. The low level of rates led to a boom in issuance by municipalities seeking to lock in low financing costs. As a result of this activity, issuance reached a record level of $354 billion in 2002 and continued to be exceptional in the first quarter of 2003. The other theme in the market during the period was the relative attractiveness of municipal bonds, which produced enough demand to absorb the record issuance. Investors, wary of volatility in the equity market and in the geopolitical arena, flocked to perceived safe haven investments. Their risk aversion counteracted growing expectations for economic recovery and rising interest rates and was a key factor in keeping interest rates at historically low levels. In their ongoing preference for low-risk assets, investors bid Treasury prices up to such high levels that municipal bonds became as attractively valued as they have ever been relative to Treasuries. Insurance companies also moved heavily into municipal bonds as their mainstay corporate bond holdings became less attractive. At the same time, issuers recognized investor concerns over economic weakness by insuring roughly 50% of all issuance. This credit enhancement feature made municipal bonds even more attractive to risk-averse investors. While lower financing costs were a boon to municipal issuers, the continuing weakness in the economy had a negative impact on municipal credit quality, particularly in the first quarter of 2003. Moody's upgrades barely exceeded the number of 4 downgrades in the first quarter, with credit quality facing continued pressure from rising social service costs and weak national and regional economic conditions. As a result, municipalities face enormous deficits in 2003, when their combined shortfall is expected to reach $90 billion. Performance along the yield curve was varied. The Fed's November rate cut fueled a rally in short-term bonds that helped pull yields lower at the front end of the curve. Despite that rally, the best performing segment of the curve was the long-intermediate portion where performance was largely driven by buying activity among institutional investors drawn to the bonds' attractive total return potential. The trust's monthly dividend of $0.0410 per share translated to a distribution rate of 5.46 percent based on the trust's closing common share market price on April 30, 2003. Based on these figures, investors would have to earn a distribution rate of 8.89 percent on a taxable investment (for an investor in the 38.60 percent federal income tax bracket) to match the tax-exempt yield provided by the trust. For the six months ended April 30, 2003, the trust produced a total return of 6.59 percent based on common share market price. By comparison, the Lehman Brothers Municipal Bond Index posted a total return of 3.59 percent for the same period. Of course, past performance is no guarantee of future results. Investment return, common share market price and net asset value will fluctuate and trust shares, when sold, may be worth more or less than their original cost. As a result of recent market activity, current performance may vary from the figures shown. For more up-to-date information, please visit vankampen.com or speak with your financial advisor. The Lehman Brothers Municipal Bond Index is an unmanaged, broad-based statistical composite of municipal bonds. Index returns do not include any sales charges or fees that would be paid by an investor purchasing the securities the index represents. Such costs would lower performance. It is not possible to invest directly in an index. For additional information, please refer to the performance summary section. Q WHAT STRATEGIES DID YOU PURSUE IN MANAGING THE TRUST? A While interest rates fell somewhat during the period, they remained largely confined to a relatively tight trading range at historically low levels. As a result, there were fewer compelling opportunities for reinvesting the proceeds of sales from the portfolio than we've seen in some time. This had the result of keeping the portfolio's turnover low relative to normal levels as we attempted to protect the trust's dividend by limiting the likelihood of having to reinvest in lower-yielding securities. Overall, our focus over the period was on positioning the portfolio to perform well in the event of rising interest rates while also maintaining an attractive yield. One of our primary methods for doing this was to purchase premium bonds with maturities of between 15 and 20 years and a shorter call date. The yield of these bonds is 5 competitive, yet their interest rate volatility is more closely related to the 10-year call feature. Our quantitative analysis showed that this segment of the yield curve offered the optimal combination of both total return potential and downside protection. Our approach also continued to emphasize active trading of highly liquid bonds to capture shifts in relative value between various sectors and state markets. For example, California was a major issuer of debt during the period, and issued so much that prices for the state's debt temporarily dropped due to the influx of supply. We took advantage of this issuance by purchasing several well-structured deals for the portfolio. We anticipate that these bonds will return to fair value, and when they do we may consider selling them. One of the sectors we avoided during the period was tobacco bonds. These bonds were issued by states seeking to securitize their future income streams resulting from settlements from class action suits against the major tobacco companies. Recent litigation in Illinois resulted in a judge awarding billions more in a suit alleging that the companies misled smokers about the amount of nicotine in "light" cigarettes. In order to appeal, the law required the companies to put up such substantial amounts of money that some began talking about potential bankruptcy, and the tobacco bonds' credit ratings and price performance suffered accordingly. Our decision not to invest in these securities was a benefit to shareholders during the period. 6 BY THE NUMBERS YOUR TRUST'S INVESTMENTS April 30, 2003 (Unaudited) THE FOLLOWING PAGES DETAIL YOUR

SIGNIFICANT ACCOUNTING POLICIES Van Kampen Investment Grade Municipal 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 will normally invest at least 80% of its total assets in tax-exempt municipal securities rated investment grade at the time of investment. The Trust commenced investment operations on November 30, 1989. 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 maintain, in a segregated account with its custodian, assets 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, 2003, the Trust had $782,220 of when-issued and 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. 19 NOTES TO FINANCIAL STATEMENTS April 30, 2003 (Unaudited) D. FEDERAL INCOME TAXES It is the Trust's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no provision for federal income taxes is required. The Trust intends to utilize provisions of the federal income tax laws which allow it to carry a realized capital loss forward for eight years following the year of the loss and offset such losses against any future realized capital gains. At October 31, 2002, the Trust had an accumulated capital loss carryforward for tax purposes of $5,473,973, which will expire between October 31, 2003 and October 31, 2010. Of this amount, $1,576,881 will expire on October 31, 2003. At April 30, 2003, the cost and related gross unrealized appreciation and depreciation are as follows: <Table> Cost of investments for tax purposes........................ $71,308,046 =========== Gross tax unrealized appreciation........................... $ 6,108,597 Gross tax unrealized depreciation........................... (2,964,505) ----------- Net tax unrealized appreciation on investments.............. $ 3,144,092 =========== </Table> 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. Distributions from net realized gains for book purposes may include short-term capital gains, which are included as ordinary income for tax purposes. As of October 31, 2002, the components of distributable earnings on a tax basis were as follows: <Table> Undistributed ordinary income............................... $3,083 </Table> Net realized gains or losses differ for financial and tax reporting purposes primarily as a result of the capitalization of reorganization and restructuring costs for tax purposes. 2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES Under the terms of the Trust's Investment Advisory Agreement, Van Kampen Investment Advisory Corp. (the "Adviser") will provide investment advice and facilities to the Trust for an annual fee payable monthly of .60% of the average daily net assets of the Trust. For the six months ended April 30, 2003, the Trust recognized expenses of approximately $2,400 representing legal services provided by Skadden, Arps, Slate, 20 NOTES TO FINANCIAL STATEMENTS April 30, 2003 (Unaudited) Meagher & Flom (Illinois), counsel to the Trust, of which a trustee of the Trust is an affiliated person. Under separate Accounting Services and Legal Services agreements, the Adviser provides accounting and legal services to the Trust. The Adviser allocates the cost of such services to each trust. For the six months ended April 30, 2003, the Trust recognized expenses of approximately $12,500 representing Van Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of providing accounting and legal services to the Trust, which are reported as part of "Other" and "Legal" expenses, respectively, in 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 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. INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from sales of investments, excluding short-term investments, were $14,189,037 and $12,703,750, respectively. 4. 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 this instance, the recognition of gain or loss is postponed until the disposal of the security underlying the futures contract. Risks may arise as a result of the potential inability of the counterparties to meet the terms of their contracts. 21 NOTES TO FINANCIAL STATEMENTS April 30, 2003 (Unaudited) 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 on U.S. Treasury Bonds and Notes and typically closes the contract prior to delivery date. 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 six months ended April 30, 2003, were as follows: <Table> <Caption> CONTRACTS Outstanding at October 31, 2002............................. 136 Futures Opened.............................................. 202 Futures Closed..............................................

PREFERRED SHARES The Trust has outstanding 250 Remarketed Preferred Shares ("RP"). Dividends are cumulative and the dividend rate is currently reset every 28 days through a remarketing process. The rate in effect on April 30, 2003 was 1.000%. During the six months ended April 30, 2003, the rates ranged from 1.000% to 1.659%. 22 NOTES TO FINANCIAL STATEMENTS April 30, 2003 (Unaudited) The Trust pays annual fees equivalent to .25% of the preferred share liquidation value for the remarketing efforts associated with the preferred shares. These fees are included as a component of "Preferred Share Maintenance" expense in the Statement of Operations. The RP are redeemable at the option of the Trust in whole or in part at the liquidation value of $100,000 per share plus accumulated and unpaid dividends. The Trust is subject to certain asset coverage tests and the RP are subject to mandatory redemption if the tests are not met. 23 DIVIDEND REINVESTMENT PLAN The Trust offers a Dividend Reinvestment Plan (the "Plan") pursuant to which Common Shareholders who are participants in the Plan may have all distributions of dividends and capital gains automatically reinvested in Common Shares of the Trust. All Common Shareholders are deemed to be participants in the Plan unless they specifically elect not to participate. Common Shareholders who elect not to participate in the Plan will receive all distributions of dividends and capital gains in cash paid by check mailed directly to the Common Shareholder by the Trust's dividend disbursing agent. HOW THE PLAN WORKS State Street Bank and Trust Company, as your Plan Agent, serves as agent for the Common Shareholders in administering the Plan. After the Trust declares a dividend or determines to make a capital gains distribution, the Plan Agent will, as agent for the participants, receive the cash payment and use it to buy Common Shares in the open market, on the New York Stock Exchange or elsewhere, for the participants' accounts. The Trust will not issue any new Common Shares in connection with the Plan. All reinvestments are in full and fractional Common Shares, 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 capital gains distribution paid subsequent to written notice of the change 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, with the written consent of the Trust, by providing at least 90 days written notice to all Participants in the Plan. 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. 24 RIGHT TO WITHDRAW All Common Shareholders of the Trust are deemed to be participants in the Plan unless they specifically elect not to participate. You may withdraw from the Plan at any time by calling 1-800-341-2929 or by writing State Street Bank and Trust Company. 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.
