In addition, this report includes the Fund's financial statements and a list of Fund investments. Market forecasts provided in this report may not necessarily come to pass. There is no assurance that the Fund will achieve its investment objective.

FUND REPORT For the year ended March 31, 2004 MARKET CONDITIONS During the fiscal year ended March 31, 2004, 30-year municipal bond yields moved in a wide range, reaching near-record lows in May and spiking upward in midsummer before stabilizing over the last six months. Interest rates fell early in the period when investors sought bonds as a haven from war-induced uncertainty. This "flight to quality" in Treasuries carried over to municipal bonds, which also enjoyed capital appreciation. Yields on 30-year AAA municipal bonds fell from 4.73 percent in March 2003 to 4.53 percent this March but ranged between a low of 4.34 percent and a high of 5.07 percent. The yield on the 30-year Treasury decreased from 4.82 percent to 4.77 percent over the fiscal year. These changes caused the municipal-to-Treasury yield ratio to decline, making municipals less attractive relative to Treasuries. However, traditional institutional investors continued to "cross over" to buy municipal bonds. Lower-rated and nonrated municipals outperformed investment-grade issues as investors attempted to maintain income in the current interest-rate environment. Tax-exempt issuance was heavy during the year. Municipalities took advantage of low interest rates to finance new projects and refinance existing debt. The surge in issuance was enough to bring municipal volume to a record $383 billion for 2003. Volume slowed significantly in the early months of 2004. PERFORMANCE ANALYSIS For the 12-month period ended March 31, 2004, the net asset value (NAV) of Morgan Stanley Municipal Income Opportunities Trust III (OIC) increased from $9.33 to $9.39 per share. Based on this change plus reinvestment of tax-free dividends totaling $0.555 per share the Fund's total NAV return was 7.11 percent. OIC's value on the New York Stock Exchange (NYSE) increased from $8.63 to $8.92 per share during the same period. Based on this change plus reinvestment of tax-free dividends, the Fund's total market return was 10.00 percent. On March 31, 2004, OIC's NYSE market price was at a 5.0 percent discount to its NAV. Monthly dividends for the second quarter of 2004, declared in March, were unchanged at $0.045 per share. The dividend reflects the level of the Fund's undistributed net investment income and projected earnings power. The Fund's level of undistributed net investment income was $0.10 per share on March 31, 2004, versus $0.12 per share 12 months earlier.(1) The Fund's duration(2) (a measure of interest-rate sensitivity) was positioned to be shorter than its benchmark, thus reducing interest-rate volatility. The Portfolio's duration was 7.4 years as compared to 8.2 years for the Lehman Brothers High Yield Municipal Bond Index. The Fund's shorter duration - -------------------------------------------------------------------------------- (1) Income earned by certain securities in the portfolio may be subject to the federal alternative minimum tax (AMT). (2) 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, Funds with shorter durations perform better in rising-rate environments, while Funds with longer durations perform better when rates decline. 2 stance limited its upside performance. The Fund's performance relative to that of its peer group, the Lipper Closed-End High Yield Municipal Debt Funds Index, was also hampered by its better-quality portfolio at a time when lower-quality issues were outperforming. We maintained our long-term commitment to diversification with the Fund's net assets of $85.5 million diversified across 67 credits in 11 sectors. New purchases were focused on health-care issues to take advantage of supply and attractive yield opportunities. The Fund's procedure for reinvesting all dividends and distributions on common shares is through purchases in the open market. This method helps support the market value of the Fund's shares. In addition, we would like to remind investors that the Trustees have approved a procedure whereby the Fund may, when appropriate, purchase 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. 3 <Table> <Caption> LARGEST SECTORS Hospital 19.1% IDR/PCR* 17.4% Recreational Facilities 15.0% Retirement & Life Care Facilities 14.7% Nursing & Health Related Facilities 10.4% </Table> <Table> <Caption> LONG-TERM CREDIT ANALYSIS Aaa/AAA 4% Aa/AA 0% A/A 3% Baa/BBB 32% Ba/BB 6% Non Rated 55% </Table> * Industrial Development/Pollution Control Revenue Data as of March 31, 2004.

Organization and Accounting Policies Morgan Stanley Municipal Income Opportunities Trust III (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a diversified, closed-end management investment company. The Fund's investment objective is to provide a high level of current income which is exempt from federal income tax. The Fund was organized as a Massachusetts business trust on February 20, 1990 and commenced operations on April 30, 1990. 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 except where collection is not expected. 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 Fund 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 Fund agrees to receive from or pay to the 15 Morgan Stanley Municipal Income Opportunities Trust III NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2004 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 Fund as unrealized gains and losses. Upon closing of the contract, the Fund 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 Fund'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 Advisor") the Fund pays the Investment Advisor an advisory fee, calculated weekly and payable monthly, by applying the annual rate of 0.50% to the Fund's weekly net assets. Pursuant to an Administration Agreement with Morgan Stanley Services Company Inc. (the "Administrator"), an affiliate of the Investment Advisor, the Fund pays an administration fee, calculated weekly and payable monthly, by applying the annual rate of 0.30% to the Fund's weekly net assets. 3. Security Transactions and Transactions with Affiliates The cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the year ended March 31, 2004 aggregated $9,967,555 and $12,840,507, respectively. Morgan Stanley Trust, an affiliate of the Investment Advisor and Administrator, is the Fund's transfer agent. At March 31, 2004, the Fund had transfer agent fees and expenses payable of approximately $5,300. The Fund has an unfunded noncontributory defined benefit pension plan covering certain independent Trustees of the Fund 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 16 Morgan Stanley Municipal Income Opportunities Trust III NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2004 continued compensation. Aggregate pension costs for the year ended March 31, 2004 included in Trustees' fees and expenses in the Statement of Operations amounted to $7,186. At March 31, 2004, the Fund had an accrued pension liability of $58,116 which is included in accrued expenses in the Statement of Assets and Liabilities. On December 2, 2003, the Trustees voted to close the plan to new participants, eliminate the future benefits growth due to increases to compensation after July 31, 2003 and effective April 1, 2004, establish an unfunded deferred 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 throughout the year. 4. Shares of Beneficial Interest Transactions in shares of beneficial interest were as follows: <Table> <Caption> CAPITAL PAID IN PAR VALUE EXCESS OF SHARES OF SHARES PAR VALUE --------- --------- ----------- Balance, March 31, 2002..................................... 9,467,173 $94,672 $89,534,129 Treasury shares purchased and retired (weighted average discount 6.71%)*..........................................

Dividends On March 30, 2004, the Fund declared the following dividends from net investment income: <Table> <Caption> AMOUNT RECORD PAYABLE PER SHARE DATE DATE - --------- -------------- ---------------- $0.045 April 16, 2004 April 30, 2004 $0.045 May 7, 2004 May 21, 2004 $0.045 June 4, 2004 June 18, 2004 </Table> 17 Morgan Stanley Municipal Income Opportunities Trust III NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2004 continued 6. Expense Offset The expense offset represents a reduction of the custodian fees for earnings on cash balances maintained by the Fund. 7. Risks Relating to Certain Financial Instruments The Fund 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 Fund 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 Fund 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. 8. 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. 18 Morgan Stanley Municipal Income Opportunities Trust III NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2004 continued The tax character of distributions paid was as follows: <Table> <Caption> FOR THE YEAR FOR THE YEAR ENDED ENDED MARCH 31, 2004 MARCH 31, 2003 -------------- -------------- Tax-exempt income........................................... $ 5,107,395 $5,346,225 =========== ========== As of March 31, 2004, the tax-basis components of accumulated losses were as follows: Undistributed tax-exempt income............................. $ 817,450 Undistributed ordinary income............................... 57,228 Undistributed long-term gains............................... -- ----------- Net accumulated earnings.................................... 874,678 Capital loss carryforward*..................................

(90,441) Net unrealized depreciation................................. (475,609) ----------- Total accumulated losses.................................... $ (964,062) =========== </Table> * During the year ended March 31, 2004, the Fund utilized $197,569 of its net capital loss carryforward. As of March 31, 2004, the Fund had a net capital loss carryforward of $1,188,743 which will expire on March 31, 2011 to offset future capital gains to the extent provided by regulations. As of March 31, 2004, the Fund had temporary book/tax differences primarily attributable to post-October losses (capital losses incurred after October 31 within the taxable year which are deemed to arise on the first business day of the Fund's next taxable year) and book amortization of discounts on debt securities and permanent book/tax differences primarily attributable to tax adjustments on debt securities sold by the Fund. To reflect reclassifications arising from the permanent differences, paid-in-capital was charged $786, accumulated net realized loss was charged $41,427 and accumulated undistributed net investment income was credited $42,213. 19 Morgan Stanley Municipal Income Opportunities Trust III NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2004 continued 9. Legal Matters The Investment Manager, certain affiliates of the Investment Manager, certain officers of such affiliates and certain investment companies advised by the Investment Manager or its affiliates, including the Fund, are named as defendants in a number of similar class action complaints which were recently consolidated. This consolidated action also names as defendants certain individual Trustees and Directors of the Morgan Stanley funds. The consolidated amended complaint generally alleges that defendants, including the Fund, violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Investment Manager and certain affiliates of the Investment Manager allegedly offered economic incentives to brokers and others to recommend the funds advised by the Investment Manager or its affiliates to investors rather than funds managed by other companies, and (ii) that the funds advised by the Investment Manager or its affiliates, including the Fund, allegedly paid excessive commissions to brokers in return for their efforts to recommend these funds to investors. The complaint seeks, among other things, unspecified compensatory damages, rescissionary damages, fees and costs. The defendants intend to move to dismiss the action and otherwise vigorously to defend it. While the Fund believes that it has meritorious defenses, the ultimate outcome of this matter is not presently determinable at this early stage of the litigation, and no provision has been made in the Fund's financial statements for the effect, if any, of this matter. 20 Morgan Stanley Municipal Income Opportunities Trust III FINANCIAL HIGHLIGHTS Selected ratios and per share data for a share of beneficial interest outstanding throughout each period: <Table> <Caption> FOR THE YEAR ENDED MARCH 31 --------------------------------------------------------------------- 2004 2003 2002 2001 2000 --------- --------- --------- --------- --------- Selected Per Share Data: Net asset value, beginning of period...................... $9.33 $ 9.32 $ 9.48 $ 9.34 $ 9.99 ----- ------ ------ ------ ------ Income (loss) from investment operations: Net investment income*................................ 0.52 0.56 0.57 0.57 0.57 Net realized and unrealized gain (loss)............... 0.09 0.01 (0.12) 0.11 (0.75) ----- ------ ------ ------ ------ Total income (loss) from investment operations............ 0.61 0.57 0.45 0.68 (0.18) ----- ------ ------ ------ ------ Less dividends and distributions from: Net investment income.................................

STATEMENT OF PRINCIPLES The Audit Committee of the Board is required to review and, in its sole discretion, pre-approve all Covered Services to be provided by the Independent Auditors to the Fund and Covered Entities in order to assure that services performed by the Independent Auditors do not impair the auditor's independence from the Fund. The SEC has issued rules specifying the types of services that an independent auditor may not provide to its audit client, as well as the audit committee's administration of the engagement of the independent auditor. The SEC's rules establish two different approaches to pre-approving services, which the SEC considers to be equally valid. Proposed services either: may be pre-approved without consideration of specific case-by-case services by the Audit Committee ("general pre-approval"); or require the specific pre-approval of the Audit Committee or its delegate ("specific pre-approval"). The Audit Committee believes that the combination of these two approaches in this Policy will result in an effective and efficient procedure to pre-approve services performed by the Independent Auditors. As set forth in this Policy, unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Committee (or by any member of the Audit Committee to which pre-approval authority has been delegated) if it is to be provided by the Independent Auditors. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval by the Audit Committee. The appendices to this Policy describe the Audit, Audit-related, Tax and All Other services that have the general pre-approval of the Audit Committee. The term of any general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee considers and provides a different period and states otherwise. The Audit Committee will annually review and pre-approve the services that may be provided by the Independent Auditors without obtaining specific pre-approval from the Audit Committee. The Audit Committee will add to or subtract from the list of general pre-approved services from time to time, based on subsequent determinations. - -------- (1) This Audit Committee Audit and Non-Audit Services Pre-Approval Policy and Procedures (the "Policy"), adopted as of the date above, supercedes and replaces all prior versions that may have been adopted from time to time. 3 The purpose of this Policy is to set forth the policy and procedures by which the Audit Committee intends to fulfill its responsibilities. It does not delegate the Audit Committee's responsibilities to pre-approve services performed by the Independent Auditors to management. The Fund's Independent Auditors have reviewed this Policy and believes that implementation of the Policy will not adversely affect the Independent Auditors' independence. 2. DELEGATION As provided in the Act and the SEC's rules, the Audit Committee may delegate either type of pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting. 3. AUDIT SERVICES The annual Audit services engagement terms and fees are subject to the specific pre-approval of the Audit Committee. Audit services include the annual financial statement audit and other procedures required to be performed by the Independent Auditors to be able to form an opinion on the Fund's financial statements. These other procedures include information systems and procedural reviews and testing performed in order to understand and place reliance on the systems of internal control, and consultations relating to the audit. The Audit Committee will approve, if necessary, any changes in terms, conditions and fees resulting from changes in audit scope, Fund structure or other items. In addition to the annual Audit services engagement approved by the Audit Committee, the Audit Committee may grant general pre-approval to other Audit services, which are those services that only the Independent Auditors reasonably can provide. Other Audit services may include statutory audits and services associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4, etc.), periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings. The Audit Committee has pre-approved the Audit services in Appendix B.1. All other Audit services not listed in Appendix B.1 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 4. AUDIT-RELATED SERVICES 4 Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review of the Fund's financial statements and, to the extent they are Covered Services, the Covered Entities or that are traditionally performed by the Independent Auditors. Because the Audit Committee believes that the provision of Audit-related services does not impair the independence of the auditor and is consistent with the SEC's rules on auditor independence, the Audit Committee may grant general pre-approval to Audit-related services. Audit-related services include, among others, accounting consultations related to accounting, financial reporting or disclosure matters not classified as "Audit services"; assistance with understanding and implementing new accounting and financial reporting guidance from rulemaking authorities; agreed-upon or expanded audit procedures related to accounting and/or billing records required to respond to or comply with financial, accounting or regulatory reporting matters; and assistance with internal control reporting requirements under Forms N-SAR and/or N-CSR. The Audit Committee has pre-approved the Audit-related services in Appendix B.2. All other Audit-related services not listed in Appendix B.2 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 5. TAX SERVICES The Audit Committee believes that the Independent Auditors can provide Tax services to the Fund and, to the extent they are Covered Services, the Covered Entities, such as tax compliance, tax planning and tax advice without impairing the auditor's independence, and the SEC has stated that the Independent Auditors may provide such services. Pursuant to the preceding paragraph, the Audit Committee has pre-approved the Tax Services in Appendix B.3. All Tax services in Appendix B.3 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 6. ALL OTHER SERVICES The Audit Committee believes, based on the SEC's rules prohibiting the Independent Auditors from providing specific non-audit services, that other types of non-audit services are permitted. Accordingly, the Audit Committee believes it may grant general pre-approval to those permissible non-audit services classified as All Other services that it believes are routine and recurring services, would not impair the independence of the auditor and are consistent with the SEC's rules on auditor independence. 5 The Audit Committee has pre-approved the All Other services in Appendix B.4. Permissible All Other services not listed in Appendix B.4 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 7. PRE-APPROVAL FEE LEVELS OR BUDGETED AMOUNTS Pre-approval fee levels or budgeted amounts for all services to be provided by the Independent Auditors will be established annually by the Audit Committee. Any proposed services exceeding these levels or amounts will require specific pre-approval by the Audit Committee. The Audit Committee is mindful of the overall relationship of fees for audit and non-audit services in determining whether to pre-approve any such services. 8. PROCEDURES All requests or applications for services to be provided by the Independent Auditors that do not require specific approval by the Audit Committee will be submitted to the Fund's Chief Financial Officer and must include a detailed description of the services to be rendered. The Fund's Chief Financial Officer will determine whether such services are included within the list of services that have received the general pre-approval of the Audit Committee. The Audit Committee will be informed on a timely basis of any such services rendered by the Independent Auditors. Requests or applications to provide services that require specific approval by the Audit Committee will be submitted to the Audit Committee by both the Independent Auditors and the Fund's Chief Financial Officer, and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC's rules on auditor independence. The Audit Committee has designated the Fund's Chief Financial Officer to monitor the performance of all services provided by the Independent Auditors and to determine whether such services are in compliance with this Policy. The Fund's Chief Financial Officer will report to the Audit Committee on a periodic basis on the results of its monitoring. Both the Fund's Chief Financial Officer and management will immediately report to the chairman of the Audit Committee any breach of this Policy that comes to the attention of the Fund's Chief Financial Officer or any member of management. 9. ADDITIONAL REQUIREMENTS The Audit Committee has determined to take additional measures on an annual basis to meet its responsibility to oversee the work of the Independent Auditors and to assure the auditor's independence from the Fund, such as reviewing a formal written statement from the Independent Auditors delineating all relationships between the Independent Auditors and the Fund, consistent with Independence Standards Board No. 6 1, and discussing with the Independent Auditors its methods and procedures for ensuring independence. 10. COVERED ENTITIES Covered Entities include the Fund's investment adviser(s) and any entity controlling, controlled by or under common control with the Fund's investment adviser(s) that provides ongoing services to the Fund(s). Beginning with non-audit service contracts entered into on or after May 6, 2003, the Fund's audit committee must pre-approve non-audit services provided not only to the Fund but also to the Covered Entities if the engagements relate directly to the operations and financial reporting of the Fund. This list of Covered Entities would include: Morgan Stanley Retail Funds Morgan Stanley Investment Advisors Inc. Morgan Stanley & Co. Incorporated Morgan Stanley DW Inc. Morgan Stanley Investment Management Morgan Stanley Investments LP Van Kampen Asset Management Inc. Morgan Stanley Services Company, Inc. Morgan Stanley Distributors Inc.

Morgan Stanley AIP GP LP Morgan Stanley Alternative Investment Partners LP (e)(2) Beginning with non-audit service contracts entered into on or after May 6, 2003, the audit committee also is required to pre-approve services to Covered Entities to the extent that the services are determined to have a direct impact on the operations or financial reporting of the Registrant. 100% of such services were pre-approved by the audit committee pursuant to the Audit Committee's pre-approval policies and procedures (attached hereto). (f) Not applicable. (g) See table above. (h) The audit committee of the Board of Trustees has considered whether the provision of services other than audit services performed by the auditors to the Registrant and 7 Covered Entities is compatible with maintaining the auditors' independence in performing audit services.
