FUND REPORT For the six months ended April 30, 2008 MARKET CONDITIONS The six-month period under review was marked by disrupted credit markets, recession fears, deterioration of the housing market, and markdowns in the mortgage market as a result of forced selling. Although the fixed income market saw some improvements in the last month of the period, many of the same concerns and problems remained. The Federal Reserve (the "Fed") stepped in several times during the period to minimize the liquidity crisis. Not only did the Federal Open Market Committee reduce the target federal funds rate several times, from 4.5 percent to 2.0 percent, but in an unprecedented move, the Fed granted primary Treasury dealers (mostly brokerage firms) access to its discount window and loosened its collateral requirements, extending loans of Treasury securities in exchange for lower quality, less liquid securities. Finally, in what was most decidedly the biggest headline event, the Fed arranged and supported JPMorgan Chase's purchase of Bear Stearns, which was viewed by many as necessary to avoid serious market repercussions had the firm failed. The decline in short-term interest rates, coupled with the risk-averse environment during the period pushed Treasury yields lower, especially on the short end of the yield curve, causing the curve to steepen. The municipal yield curve steepened as well, with the yield differential between one-year and 30- year maturities reaching more than 300 basis points. Overall, municipal bonds underperformed their taxable counterparts as credit rating downgrades of various monoline bond insurers and the deterioration of the auction rate and variable rate markets posed additional challenges for the sector. After a record year for new municipal bond issuance in 2007, the amount of new issues coming to market in the first four months of 2008 declined. PERFORMANCE ANALYSIS For the six-month period ended April 30, 2008, the net asset value (NAV) of Morgan Stanley Quality Municipal Investment Trust (IQT) decreased from $14.50 to $13.98 per share. Based on this change plus reinvestment of tax-free dividends totaling $0.345 per share, the Trust's total NAV return was -0.94 percent. IQT's value on the New York Stock Exchange (NYSE) moved from $13.00 to $12.79 per share during the same period. Based on this change plus reinvestment of dividends, the Trust's total market return was 1.09 percent. IQT's NYSE market price was at an 8.51 percent discount to its NAV. During the fiscal period, the Trust purchased and retired 153,214 shares of common stock at a weighted average market discount of 10.51 percent. Past performance is no guarantee of future results. Monthly dividends for the second quarter of 2008, declared in April, were unchanged at $0.0575 per share. The dividend reflects the current level of the Trust's net investment income. IQT's level of undistributed net investment income was $0.067 per share on April 30, 2008 versus $0.050 per share six months earlier.(1) Throughout the six-month period, the Trust maintained a lower interest rate sensitivity (as measured by duration*), which was implemented through the use of a U.S. Treasury futures hedge. This defensive positioning benefited performance as it helped to minimize the price declines that resulted from rising 2 yields across the intermediate and long end of the municipal yield curve. In terms of the Trust's sector positioning, an overweight in the hospital/life care and tobacco sectors detracted from relative performance as spread widening in those sectors hindered returns. Conversely, an overweight in the public utility sector, particularly water and sewer bonds, benefited performance. The flight to quality that took place during the period helped boost the performance of the more solid infrastructure sectors such as utilities and the Trust's holdings there enhanced returns. The Trust's procedure for reinvesting all dividends and distributions in common shares is through purchases in the open market. This method helps support the market value of the Trust's shares. In addition, we would like to remind you that the Trustees have approved a procedure whereby the Trust may, when appropriate, purchase shares in the open market or in privately negotiated transactions at a price not above market value or net asset value, whichever is lower at the time of purchase. The Trust may also utilize procedures to reduce or eliminate the amount of Auction Rate Preferred Shares (ARPS) outstanding, including their purchase in the open market or in privately negotiated transactions. - -------------------------------------------------------------------------------- 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. 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. (1) Income earned by certain securities in the portfolio may be subject to the federal alternative minimum tax (AMT). * A measure of the sensitivity of a bond's price to changes in interest rates, expressed in years. Each year of duration represents an expected 1 percent change in the price of a bond for every 1 percent change in interest rates. The longer a bond's duration, the greater the effect of interest-rate movements on its price. Typically, trusts with shorter durations perform better in rising- interest-rate environments, while trusts with longer durations perform better when rates decline. Duration calculations are adjusted for leverage. 3 <Table> <Caption> TOP FIVE SECTORS AS OF 04/30/08 General Obligation 13.8% Hospital 13.0 Water & Sewer 12.1 Transportation 11.2 Other Revenue 10.7 </Table> <Table> <Caption> LONG-TERM CREDIT ANALYSIS AS OF 04/30/08 Aaa/AAA 47.4 Aa/AA 23.3 A/A 16.8 Baa/BBB 10.6 Ba/BB 0.3 N/R 1.6 </Table> <Table> <Caption> SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 04/30/08 California 22.7% Florida 16.9 Texas 16.3 New York 15.9 Georgia 11.9 New Jersey 8.6 South Carolina 6.2 Kentucky 5.9 Washington 5.8 Maryland 4.9 Pennsylvania 4.6 Colorado 4.5 Tennessee 4.4 Hawaii 3.9 Michigan 3.3 Alaska 3.2 Nevada 3.1 Indiana 3.1 District of Columbia 3.0 Illinois 2.0 </Table> <Table> <Caption> SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION (CONTINUED) Iowa 1.7% Ohio 1.6 Utah 1.6 North Carolina 1.1 Nebraska 1.0 Alabama 1.0 Missouri 1.0 Virginia 0.8 Arizona 0.5 New Mexico 0.5 Idaho 0.4 Massachusetts 0.2 ------ Total Long-Term Investments+ 161.6 Short-Term Investment 3.0 Liability for Floating Rate Note and Dealer Trust Obligations -10.9 Other Assets in Excess of Liabilities 0.5 Preferred Shares of Beneficial Interest -54.2 ------ Net Assets Applicable to Common Shareholders 100.0% ====== </Table> + Does not include open long/short futures contracts with an underlying face value amount of $57,669,689 with unrealized appreciation of $290,068 and swap contracts with an unrealized depreciation of $71,972.

Organization and Accounting Policies Morgan Stanley Quality Municipal Investment Trust (the "Trust") is registered under the Investment Company Act of 1940, as amended, as a diversified, closed- end management investment company. The Trust's investment objective is to provide current income which is exempt from federal income tax. The Trust was organized as a Massachusetts business trust on July 2, 1991 and commenced operations on September 27, 1991. The following is a summary of significant accounting policies: A. Valuation of Investments -- (1) portfolio securities are valued by an outside independent pricing service approved by the Trustees. The pricing service uses both a computerized grid matrix of tax-exempt securities and evaluations by its staff, in each case based on information concerning market transactions and quotations from dealers which reflect the mean between the last reported bid and asked price. The portfolio securities are thus valued by reference to a combination of transactions and quotations for the same or other securities believed to be comparable in quality, coupon, maturity, type of issue, call provisions, trading characteristics and other features deemed to be relevant. The Trustees believe that timely and reliable market quotations are generally not readily available for purposes of valuing tax-exempt securities and that the valuations supplied by the pricing service are more likely to approximate the fair value of such securities; (2) futures are valued at the latest sale price on the commodities exchange on which they trade unless it is determined that such price does not reflect their market value, in which case they will be valued at their fair value as determined in good faith under procedures established by and under the supervision of the Trustees; (3) interest rate swaps are marked-to-market daily based upon quotations from market makers; (4) investments in open-end mutual funds, including the Morgan Stanley Institutional Liquidity Funds, are valued at the net asset value as of the close of each business day; and (5) short-term debt securities having a maturity date of more than sixty days at time of purchase are valued on a mark-to-market basis until sixty days prior to maturity and thereafter at amortized cost based on their value on the 61st day. Short-term debt securities having a maturity date of sixty days or less at the time of purchase are valued at amortized cost. B. Accounting for Investments -- Security transactions are accounted for on the trade date (date the order to buy or sell is executed). Realized gains and losses on security transactions are determined by the identified cost method. Discounts are accreted and premiums are amortized over the life of the respective securities and are included in interest income. Interest income is accrued daily. C. Futures Contracts -- A futures contract is an agreement between two parties to buy and sell financial instruments or contracts based on financial indices at a set price on a future date. Upon 19 Morgan Stanley Quality Municipal Investment Trust NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued entering into such a contract, the Trust is required to pledge to the broker cash, U.S. Government securities or other liquid portfolio securities equal to the minimum initial margin requirements of the applicable futures exchange. Pursuant to the contract, the Trust agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments known as variation margin are recorded by the Trust as unrealized gains and losses. Upon closing of the contract, the Trust realizes a gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. D. Floating Rate Note and Dealer Trust Obligations Related to Securities Held -- The Trust enters into transactions in which it transfers to Dealer Trusts ("Dealer Trusts"), fixed rate bonds in exchange for cash and 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 interest 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 liquidations 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 and dealer trust obligations" on the Statement of Assets and Liabilities. The Trust records the interest income from the fixed rate bonds under the caption "Interest Income" and records the expenses related to floating rate note obligations and any administrative expenses of the Dealer Trusts under the caption "Interest and residual trust expenses" in the Trust's statement of Operations. The notes issued by the Dealer 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, 2008, Trust investments with a value of $27,062,331 are held by the Dealer Trusts and serve as collateral for the $21,105,080 in the floating rate note and dealer trusts obligations outstanding at that date. Contractual maturities of the floating rate note obligations and interest rates in effect at April 30, 2008 are presented in the Portfolio of Investments. E. Interest Rate Swaps -- Interest rate swaps involve the exchange of commitments to pay and receive interest based on a notional principal amount. Net periodic interest payments to be received or paid are accrued daily and are recorded as realized gains or losses in the Statement of 20 Morgan Stanley Quality Municipal Investment Trust NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued Operations. The Trust may pay or receive cash to collateralize interest rate swap contracts. Any cash received may be invested in Morgan Stanley Institutional Liquidity Funds. F. Federal Income Tax Policy -- 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 and non taxable income to its shareholders. Therefore, no provisions for federal income taxes is required. The Trust files tax returns with the U.S. Internal Revenue Service, New York State and New York City. The Trust adopted the provisions of the Financial Accounting Standards Board ("FASB") Interpretation No. 48 ("FIN 48") Accounting for Uncertainty in Income Taxes, on April 29, 2008. FIN 48 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The implementation of FIN 48 did not result in any unrecognized tax benefits in the accompanying financial statements. If applicable, the Trust recognizes the interest accrued related to unrecognized tax benefits in the interest expense and penalties in other expenses in the Statement of Operations. Each of the tax years in the four year period ended April 30, 2008, remains subject to examination by taxing authorities. G. Dividends and Distributions to Shareholders -- Dividends and distributions to shareholders are recorded on the ex-dividend date. H. Use of Estimates -- The preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and disclosures. Actual results could differ from those estimates. 2. Investment Advisory/Administration Agreements Pursuant to an Investment Advisory Agreement with Morgan Stanley Investment Advisors Inc. (the "Investment Adviser"), the Trust pays an advisory fee, calculated weekly and payable monthly, by applying the annual rate of 0.27% to the Trust's average weekly net assets including preferred shares. Pursuant to an Administration Agreement with Morgan Stanley Services Company Inc. (the "Administrator"), an affiliate of the Investment Adviser, the Trust pays an administration fee, calculated weekly and payable monthly, by applying the annual rate of 0.08% to the Trust's average weekly net assets including preferred shares. Under an agreement between the Administrator and State Street Bank and Trust Company ("State Street"), State Street provides certain administrative services to the Trust. For such services, the Administrator pays State Street a portion of the fee the Administrator receives from the Trust. 21 Morgan Stanley Quality Municipal Investment Trust NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued 3. Security Transactions and Transactions with Affiliates The Trust invests in Morgan Stanley Institutional Liquidity Tax-Exempt Portfolio -- Institutional Class, an open-end management investment company managed by the Investment Adviser. Investment advisory fees paid by the Trust are reduced by an amount equal to the advisory and administrative service fees paid by Morgan Stanley Institutional Liquidity Tax-Exempt Portfolio -- Institutional Class with respect to assets invested by the Trust in Morgan Stanley Institutional Liquidity Tax-Exempt Portfolio -- Institutional Class. For the six months ended April 30, 2008, advisory fees paid were reduced by $3,626 relating to the Trust's investment in Morgan Stanley Institutional Liquidity Tax-Exempt Portfolio -- Institutional Class. Income distributions earned by the Trust are recorded as dividends from affiliate in the Statement of Operations and totaled $92,728 for the six months ended April 30, 2008. During the six months ended April 30, 2008, cost of purchases and sales of Morgan Stanley Institutional Liquidity Tax-Exempt Portfolio -- Institutional Class aggregated $23,536,373 and $23,194,683, respectively. The cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the six months ended April 30, 2008 aggregated $17,471,193 and $15,264,967, respectively. The Trust has an unfunded noncontributory defined benefit pension plan covering certain independent Trustees of the Trust who will have served as independent Trustees for at least five years at the time of retirement. Benefits under this plan are based on factors which include years of service and compensation. The Trustees voted to close the plan to new participants and eliminate the future benefits growth due to increases to compensation after July 31, 2003. Aggregate pension costs for the six months ended April 30, 2008, included in Trustees' fees and expenses in the Statement of Operations amounted to $2,644. At April 30, 2008, the Trust had an accrued pension liability of $56,581 which is included in accrued expenses in the Statement of Assets and Liabilities. The Trust has an unfunded Deferred Compensation Plan (the "Compensation Plan") which allows each independent Trustee to defer payment of all, or a portion, of the fees he or she receives for serving on the Board of Trustees. Each eligible Trustee generally may elect to have the deferred amounts credited with a return equal to the total return on one or more of the Morgan Stanley funds that are offered as investment options under the Compensation Plan. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Trust. 22 Morgan Stanley Quality Municipal Investment Trust NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued 4. Preferred Shares of Beneficial Interest The Trust is authorized to issue up to 1,000,000 non-participating preferred shares of beneficial interest having a par value of $.01 per share, in one or more series, with rights as determined by the Trustees, without approval of the common shareholders. The Trust has issued Series A and B Auction Rate Preferred Shares ("preferred shares") which have a liquidation value of $50,000 per share plus the redemption premium, if any, plus accumulated but unpaid dividends, whether or not declared, thereon to the date of distribution. The Trust may redeem such shares, in whole or in part, at the original purchase price of $50,000 per share plus accumulated but unpaid dividends, whether or not declared, thereon to the date of redemption. Dividends, which are cumulative, are reset through auction procedures. <Table> <Caption> AMOUNT IN RESET RANGE OF SERIES SHARES+ THOUSANDS+ RATE+ DATE DIVIDEND RATES++ - ------ ------- ---------- ----- -------- ---------------- A 1,400 $70,000 2.377% 05/07/08 2.377% - 4.60% B 700 35,000 2.421 05/02/08 2.322 - 4.70 </Table> - ---------- + As of April 30, 2008. ++ For the six months ended April 30, 2008. Subsequent to April 30, 2008 and up through June 6, 2008, the Trust paid dividends to Series A and B at rates ranging from 1.971% to 2.377%, in the aggregate amount of $242,732. The Trust is subject to certain restrictions relating to the preferred shares. Failure to comply with these restrictions could preclude the Trust from declaring any distributions to common shareholders or purchasing common shares and/or could trigger the mandatory redemption of preferred shares at liquidation value. The preferred shares, which are entitled to one vote per share, generally vote with the common shares but vote separately as a class to elect two Trustees and on any matters affecting the rights of the preferred shares. 23 Morgan Stanley Quality Municipal Investment Trust NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued 5. Common Shares of Beneficial Interest Transactions in common shares of beneficial interest were as follows: <Table> <Caption> CAPITAL PAID IN EXCESS OF SHARES PAR VALUE PAR VALUE ---------- --------- ------------ Balance, October 31, 2006....................... 14,383,944 $143,839 $200,986,955 Treasury shares purchased and retired (weighted average discount 7.64%)+++....................

Dividends to Common Shareholders On April 8, 2008, the Trust declared the following dividends from net investment income: <Table> <Caption> AMOUNT RECORD PAYABLE PER SHARE DATE DATE - --------- ------------ ------------- $0.0575 May 23, 2008 May 30, 2008 $0.0575 June 20 2008 June 27, 2008 </Table> 7. Expense Offset The expense offset represents a reduction of the fees and expenses for interest earned on cash balances maintained by the Trust with the transfer agent and custodian. 8. Purposes of and Risks Relating to Certain Financial Instruments 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 (See Note 1D). 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 24 Morgan Stanley Quality Municipal Investment Trust NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued 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. To hedge against adverse interest rate changes, the Trust may invest in financial futures contracts or municipal bond index futures contracts ("futures contracts"). These futures contracts involve elements of market risk in excess of the amount reflected in the Statement of Assets and Liabilities. The Trust bears the risk of an unfavorable change in the value of the underlying securities. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts. The Trust may enter into interest rate swaps and may purchase or sell interest rate caps, floors and collars. The Trust expects to enter into these transactions primarily to manage interest rate risk, hedge portfolio positions and preserve a return or spread on a particular investment or portion of its portfolio. The Trust may also enter into these transactions to protect against any increase in the price of securities the Trust anticipates purchasing at a later date. Interest rate swap transactions are subject to market risk, risk of default by the other party to the transaction, risk of imperfect correlation and manager risk. Such risks may exceed the related amounts shown in the Statements of Assets and Liabilities. 9. Federal Income Tax Status The amount of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations which may differ from generally accepted accounting principles. These "book/tax" differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax-basis treatment; temporary differences do not require reclassification. Dividends and distributions which exceed net investment income and net realized capital gains for tax purposes are reported as distributions of paid-in-capital. As of October 31, 2007, the Trust had temporary book/tax differences primarily attributable to book amortization of discounts on debt securities and mark-to- market of open futures contracts. 10. Accounting Pronouncements On March 19, 2008, FASB released Statement of Financial Accounting Standards No. 161, "Disclosures about Derivative Instruments and Hedging Activities" ("FAS 161"). FAS 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about 25 Morgan Stanley Quality Municipal Investment Trust NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2008 (UNAUDITED) continued credit- risk-related contingent features in derivative agreements. The application of FAS 161 is required for fiscal years beginning after November 15, 2008 and interim periods within those fiscal years. At this time, management is evaluating the implications of FAS 161 and its impact on the financial statements has not been determined. 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. 26 Morgan Stanley Quality Municipal Investment Trust FINANCIAL HIGHLIGHTS Selected ratios and per share data for a common share of beneficial interest outstanding throughout each period: <Table> <Caption> FOR THE SIX FOR THE YEAR ENDED OCTOBER 31, MONTHS ENDED ------------------------------------------------- APRIL 30, 2008 2007 2006 2005 --------------- --------------- ----------- ----------- (unaudited) Selected Per Share Data: Net asset value, beginning of period......... $ 14.50 $ 15.25 $ 15.29 $ 15.64 -------- -------- -------- -------- Income (loss) from investment operations: Net investment income(1).................. 0.49 0.97 0.93 0.95 Net realized and unrealized gain (loss)...

As a result of changes in the fixed-income and municipal marketplace, the Trust's average portfolio maturity will vary depending upon market conditions and other factors. 28 Morgan Stanley Quality Municipal Investment Trust MORGAN STANLEY ADVISOR CLOSED END FUNDS AN IMPORTANT NOTICE CONCERNING OUR U.S. PRIVACY POLICY (UNAUDITED) We are required by federal law to provide you with a copy of our Privacy Policy annually.
