FUND REPORT For the six months ended April 30, 2006 MARKET CONDITIONS The U.S. economy navigated a number of challenges and continued to grow during the reporting period, with particular strong expansion in 2006. Although the Gulf Coast hurricanes resulted in unprecedented devastation, the negative impact on the economy was less far-reaching than many had originally anticipated. Even sharply higher energy prices failed to interrupt the positive economic momentum. In 2006, developing weakness in the real estate sector and elevated commodity prices weighed on sentiment. Yet, strong manufacturing surveys, buoyant consumer confidence and positive employment data pointed toward steady growth in real gross domestic product. While sustained higher energy costs began to push some prices upward, headline measures of inflation remained largely stable. Given the economy's solid growth, the Federal Open Market Committee (the "Fed") continued to raise the federal funds target rate. Through four increases of 25 basis points each, the Fed brought the rate from 3.75 percent to 4.75 percent during the period. Yields on short-term municipal bonds followed the target rate and rose steadily. In contrast, the yields of long-term bonds initially declined before moving higher in April. Representative yields on 30-year AAA rated municipal bonds declined from 4.60 percent in October 2005 to a low of 4.30 percent in February, before ending the period at 4.55 percent. Accordingly, the slope of the municipal yield curve continued to flatten as the difference between short-term and long-term interest rates narrowed. In this environment, the benefits of leveraged investment strategies were less pronounced. (Leverage involves borrowing at short-term rates to purchase longer-term securities, thereby taking advantage of the differential between short- and long-term yields.) Investors' quest for yield favored lower-quality bonds over high-grade issues and kept credit spreads relatively tight. (Credit spreads measure the incremental yield investors require to assume additional credit risk. When credit spreads tighten, lower-rated issues typically outperform high-grade issues.) Demand for municipal bonds strengthened among individual and institutional investors alike. Meanwhile, municipal bond supply dropped significantly as the period progressed. New issue volume continued to be robust in the final months of 2005, supporting the record pace of issuance during the calendar year (more than $400 billion). However, volume in the first four months of 2006 fell by nearly 25 percent compared to the same period in 2005. The decline was largely attributable to a slowdown in refundings, which dropped by more than 55 percent as rising interest rates discouraged municipalities from refinancing debt. Improved fiscal conditions among state and local governments also contributed to less significant borrowing needs. Bonds backed by insurance fell to under 50 percent of issuance in 2006, from nearly 60 percent in 2005. Issuers in California, Texas, New York, Florida and Illinois accounted for over 40 percent of the total underwriting volume in 2006. 2 Reflecting declining supply and sustained demand, municipal bonds outperformed U.S. Treasuries with comparable maturities. That said, the relative attractiveness of tax-exempt bonds ebbed somewhat, and the 30-year municipal-to-Treasury yield ratio steadily declined from 97 to 88 percent. (The municipal-to-Treasury yield ratio measures the relative attractiveness of the two sectors. The higher the ratio, the greater the attractiveness of municipal yields relative to Treasury yields.) PERFORMANCE ANALYSIS For the six-month period ended April 30, 2006, the net asset value (NAV) of Morgan Stanley Quality Municipal Investment Trust (IQT) decreased from $15.29 to $14.77 per share. Based on this change plus reinvestment of tax-free dividends totaling $0.39 per share, a short-term capital gain distribution of $0.039016 per share and a long-term capital gain distribution of $0.375985 per share, the Trust's total NAV return was 2.52 percent. IQT's value on the New York Stock Exchange (NYSE) moved from $13.62 to $13.61 per share during the same period. Based on this change plus reinvestment of dividends and distributions, the Trust's total market return was 6.05 percent. IQT's NYSE market price was at a 7.85 percent discount to its NAV. During the fiscal period, the Trust purchased and retired 369,400 shares of common stock at a weighted average market discount of 9.96 percent. Past performance is no guarantee of future results. Monthly dividends for the second quarter of 2006, declared in March, were unchanged at $0.065 per share. The dividend reflects the current level of the Trust's net investment income. IQT's level of undistributed net investment income was $0.058 per share on April 30, 2006, versus $0.096 per share six months earlier.(1) In anticipation of continued Fed tightening and generally higher interest rates, the Trust made modest ongoing adjustments to its portfolio to reduce volatility. For example, a U.S. Treasury futures strategy was used to reduce the portfolio's duration,* as a hedge against rising rates. At the end of April, the Trust's option-adjusted duration was 11.7 years. This duration positioning tempered the Trust's total returns when rates declined, but helped total returns when rates rose. Overall, the Trust maintained a high average credit quality with nearly 80 percent of the bonds in the portfolio rated AA or higher at the end of the period. The Trust slightly increased its exposure to A and BBB rated investment-grade credits; this had a positive impact on performance as lower-rated issues outperformed high-grade bonds. (High-grade bonds are rated AA and above.) Purchases during the period included bonds with maturities in the 25- to 30-year range and defensive characteristics. Investments continued to emphasize essential service sectors such as education, transportation, and water and sewer. The Trust also favored bonds with strong in-state investor demand. Reflecting a commitment to diversification, the Trust's 3 net assets of approximately $321 million, including preferred shares, were invested among 17 long-term sectors and 80 credits. As discussed in previous reports, the total income available for distribution to holders of common shares includes incremental income provided by the Trust's outstanding Auction Rate Preferred Shares (ARPS). ARPS dividends reflect prevailing short-term interest rates on maturities ranging from one week to two years. Incremental income to holders of common shares depends on two factors: the amount of ARPS outstanding and the spread between the portfolio's cost yield and its ARPS auction rate and expenses. The greater the spread and the higher the amount of ARPS outstanding, the greater the amount of incremental income available for distribution to holders of common shares. The level of net investment income available for distribution to holders of common shares varies with the level of short-term interest rates. ARPS leverage also increases the price volatility of common shares and has the effect of extending portfolio duration. During this six-month period, ARPS leverage contributed approximately $0.05 share to common-share earnings. The Trust has two ARPS series totaling $105 million, representing 33 percent of net assets, including preferred shares as of the end of the period. At the end of April the weekly ARPS was 3.41 percent compared to 2.55 percent at the end of October 2005. 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 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.

(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 when rates decline. 4 <Table> <Caption> TOP FIVE SECTORS Water & Sewer 27.2% Transportation 25.5 General Obligation 20.9 Healthcare 15.7 Electric 14.7 </Table> <Table> <Caption> LONG-TERM CREDIT ANALYSIS Aaa/AAA 66% Aa/AA 13% A/A 14% Baa/BBB 6% N/R 1% </Table> Data as of April 30, 2006.

The Board also reviewed and considered the nature and extent of the non-advisory, administrative services provided by the Trust's Administrator under the Administration Agreement, including accounting, clerical, bookkeeping, compliance, business management and planning, and the provision of supplies, office space and utilities at the Investment Adviser's expense. (The Investment Adviser and the Administrator together are referred to as the "Adviser" and the Advisory and Administration Agreements together are referred to as the "Management Agreement.") The Board also compared the nature of the services provided by the Adviser with similar services provided by non-affiliated advisers as reported to the Board by Lipper Inc. ("Lipper"). The Board reviewed and considered the qualifications of the portfolio managers, the senior administrative managers and other key personnel of the Adviser who provide the administrative and advisory services to the Trust. The Board determined that the Adviser's portfolio managers and key personnel are well qualified by education and/or training and experience to perform the services in an efficient and professional manner. The Board concluded that the nature and extent of the advisory and administrative services provided were necessary and appropriate for the conduct of the business and investment activities of the Trust. The Board also concluded that the overall quality of the advisory and administrative services was satisfactory. PERFORMANCE RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS On a regular basis, the Board reviews the performance of all funds in the Morgan Stanley Fund Complex, including the Trust, compared to their peers, paying specific attention to the underperforming funds. In addition, the Board specifically reviewed the Trust's performance for the one-, three- and five-year periods ended November 30, 2005, as shown in a report provided by Lipper (the "Lipper Report"), compared to the performance of comparable funds selected by Lipper (the "performance peer group"). The Board also discussed with the Adviser the performance goals and the actual results achieved in managing the Trust. When a fund underperforms its performance peer group, the Board discusses with the Adviser the causes of the underperformance and, where necessary, specific changes to the fund's investment strategy or investment personnel. The Board concluded that the Trust can reasonably be expected to be competitive with that of its performance peer group based on recent action taken or proposed to be taken by the Adviser with respect to the Trust's investment strategy and/or investment personnel. 8 FEES RELATIVE TO OTHER PROPRIETARY FUNDS MANAGED BY THE ADVISER WITH COMPARABLE INVESTMENT STRATEGIES The Board reviewed the advisory and administrative fee (together, the "management fee") rate paid by the Trust under the Management Agreement. The Board noted that the management fee rate was comparable to the management fee rates charged by the Adviser to other proprietary funds it manages with investment strategies comparable to those of the Trust. FEES AND EXPENSES RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS The Board reviewed the management fee rate and total expense ratio of the Trust as compared to the average management fee rate and average total expense ratio for funds, selected by Lipper (the "expense peer group"), managed by other advisers with investment strategies comparable to those of the Trust, as shown in the Lipper Report. The Board concluded that the Trust's management fee rate and total expense ratio were competitive with those of its expense peer group. BREAKPOINTS AND ECONOMIES OF SCALE The Board reviewed the structure of the Trust's management fee schedule under the Management Agreement and noted that it does not include any breakpoints. The Board considered that the Trust is a closed-end fund and, therefore, that the Trust's assets are not likely to grow with new sales or grow significantly as a result of capital appreciation. The Board concluded that economies of scale for the Trust were not a factor that needed to be considered at the present time. PROFITABILITY OF THE ADVISER AND AFFILIATES The Board considered information concerning the costs incurred and profits realized by the Adviser and affiliates during the last year from their relationship with the Trust and during the last two years from their relationship with the Morgan Stanley Fund Complex and reviewed with the Adviser the cost allocation methodology used to determine the profitability of the Adviser and affiliates. Based on its review of the information it received, the Board concluded that the profits earned by the Adviser and affiliates were not excessive in light of the advisory, administrative and other services provided to the Trust. FALL-OUT BENEFITS The Board considered so-called "fall-out benefits" derived by the Adviser and affiliates from their relationship with the Trust and the Morgan Stanley Fund Complex, such as commissions on the purchase and sale of Trust shares and "float" benefits derived from handling of checks for purchases and sales of Trust shares, through a 9 broker-dealer affiliate of the Adviser. The Board concluded that the float benefits were relatively small and that the commissions were competitive with those of other broker-dealers. SOFT DOLLAR BENEFITS The Board considered whether the Adviser realizes any benefits from commissions paid to brokers who execute securities transactions for the Trust ("soft dollars"). The Board noted that the Trust invests only in fixed income securities, which do not generate soft dollars. ADVISER FINANCIALLY SOUND AND FINANCIALLY CAPABLE OF MEETING THE TRUST'S NEEDS The Board considered whether the Adviser is financially sound and has the resources necessary to perform its obligations under the Management Agreement. The Board noted that the Adviser's operations remain profitable, although increased expenses in recent years have reduced the Adviser's profitability. The Board concluded that the Adviser has the financial resources necessary to fulfill its obligations under the Management Agreement. HISTORICAL RELATIONSHIP BETWEEN THE TRUST AND THE ADVISER The Board also reviewed and considered the historical relationship between the Trust and the Adviser, including the organizational structure of the Adviser, the policies and procedures formulated and adopted by the Adviser for managing the Trust's operations and the Board's confidence in the competence and integrity of the senior managers and key personnel of the Adviser. The Board concluded that it is beneficial for the Trust to continue its relationship with the Adviser. OTHER FACTORS AND CURRENT TRENDS The Board considered the controls and procedures adopted and implemented by the Adviser and monitored by the Trust's Chief Compliance Officer and concluded that the conduct of business by the Adviser indicates a good faith effort on its part to adhere to high ethical standards in the conduct of the Trust's business. GENERAL CONCLUSION After considering and weighing all of the above factors, the Board concluded that it would be in the best interest of the Trust and its shareholders to approve renewal of the Management Agreement for another year. 10 Morgan Stanley Quality Municipal Investment Trust PORTFOLIO OF INVESTMENTS -

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; and (3) 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. 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 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 20 Morgan Stanley Quality Municipal Investment Trust NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2006 (UNAUDITED) continued 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. Federal Income Tax Policy -- 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 and nontaxable income to its shareholders. Accordingly, no federal income tax provision is required. E. Dividends and Distributions to Shareholders -- Dividends and distributions to shareholders are recorded on the ex-dividend date. F. 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 weekly total 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 weekly total net assets including preferred shares. 3. Security Transactions and Transactions with Affiliates The cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the six months ended April 30, 2006, aggregated $15,754,460 and $21,949,780, respectively. Morgan Stanley Trust, an affiliate of the Investment Adviser and Administrator, is the Trust's transfer agent. 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 21 Morgan Stanley Quality Municipal Investment Trust NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2006 (UNAUDITED) continued benefits growth due to increases to compensation after July 31, 2003. Aggregate pension costs for the six months ended April 30, 2006 included in Trustees' fees and expenses in the Statement of Operations amounted to $3,557. At April 30, 2006, the Trust had an accrued pension liability of $59,477 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 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. 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 Series 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 RESET RANGE OF SERIES SHARES* IN THOUSANDS* RATE* DATE DIVIDEND RATES** - ------ ------- ------------- ----- -------- ---------------- A 1,400 $70,000 2.09% 09/05/06 2.09% B 700 35,000 3.41 05/04/06 2.55- 3.75 </Table> - --------------------- * As of April 30, 2006. ** For the six months ended April 30, 2006. Subsequent to April 30, 2006 and up through June 2, 2006 the Trust paid dividends to Series A and B at rates ranging from 2.09% to 3.55% in the aggregate amount of $341,951. 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. 22 Morgan Stanley Quality Municipal Investment Trust NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2006 (UNAUDITED) continued 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. 5.

Expense Offset The expense offset represents a reduction of custodian and transfer agent fees and expenses for earnings on cash balances maintained by the Trust. 8. Risks Relating to Certain Financial Instruments The Trust may invest a portion of its assets in residual interest bonds, which are inverse floating rate municipal obligations. The prices of these securities are subject to greater market fluctuations during periods of changing prevailing interest rates than are comparable fixed rate obligations. To hedge against adverse interest rate changes, the Trust may invest in financial futures contracts or municipal bond index futures contracts ("futures contracts"). 23 Morgan Stanley Quality Municipal Investment Trust NOTES TO FINANCIAL STATEMENTS - APRIL 30, 2006 (UNAUDITED) continued 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. 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, 2005, the Trust had temporary book/tax differences primarily attributable to book amortization of discounts on debt securities, mark-to-market of open futures contracts and dividend payable. 24 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, 2006 2005 2004 2003 2002 2001 -------------- -------- -------- -------- -------- -------- (unaudited) Selected Per Share Data: Net asset value, beginning of period......... $15.29 $15.64 $15.36 $15.23 $15.31 $14.64 ------ ------ ------ ------ ------ ------ Income (loss) from investment operations: Net investment income*................... 0.46 0.95 0.96 1.01 1.07 1.17 Net realized and unrealized gain (loss)...................................

The inverse floating rate municipal obligations in which the Trust will invest are typically created through a division of a fixed rate municipal obligation into two separate instruments, a short-term obligation and a long-term obligation. The interest rate on the short-term obligation is set at periodic auctions. The interest rate on the long-term obligation is the rate the issuer would have paid on the fixed income obligation: (i) plus the difference between such fixed rate and the rate on the short-term obligation, if the short-term rate is lower than the fixed rate; or (ii) minus such difference if the interest rate on the short-term obligation is higher than the fixed rate. The interest rates on these obligations generally move in the reverse direction of market interest rates. If market interest rates fall, the interest rate on the obligation will increase and if market interest rates increase, the interest rate on the obligation will fall. Inverse floating rate municipal obligations offer the potential for higher income than is available from fixed rate obligations of comparable maturity and credit rating. They also carry greater risks. In particular, the prices of inverse floating rate municipal obligations are more volatile, i.e., they increase and decrease in response to changes in interest rates to a greater extent than comparable fixed rate obligations. 27 TRUSTEES Michael Bozic Charles A.
