PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE INFORMATION. MARKET CONDITIONS In 2003, municipal bonds experienced a wide range of market conditions with yields reaching record lows before spiking upward and ending the year near where they began. Interest rates fell through the first six months of the period as investors sought the relative safe haven of the bond market. This war-induced "flight to quality" included municipal bonds, which appreciated as a result of falling yields. That said, municipals lagged the market leadership of Treasuries and yields on 10- and 30-year insured municipal bonds at times surpassed comparable Treasury yields. This disparity created demand from value-oriented taxable institutional investors who "crossed over" to buy municipal bonds. The bond rally reversed in mid-year, however, when 10-year Treasury yields suffered their single greatest one-month increase in more than 20 years. While municipal yields also rose, performance relative to Treasuries improved as the ratio of municipal yields to Treasuries declined across maturities. Issuance was heavy during the first half of the year as municipalities sought to take advantage of low interest rates. Volume began to drop off in August as rising interest rates slowed refundings. Even with the slowdown, municipal volume reached a record $383 billion for the year. California increased that state's share of total volume to 15 percent. New York, Illinois, Texas and Florida, the next largest states in terms of issuance, represented an additional 29 percent of the national total. Issues enhanced with bond insurance maintained a 49 percent market share. California's economic recovery has been slower than expected with the unemployment rate continuing above the national average. As a result of the recall election the new governor is also attempting to address the country's largest budget gap measured as a percent of appropriations. This difficult situation led both Standard & Poor's and Moody's to downgrade the state's general obligations during the summer of 2003, with additional downgrades by Moody's and Fitch in December. Because of these credit concerns California general obligation bonds underperformed the municipal market. PERFORMANCE ANALYSIS Because the California market lagged the national averages, the Fund underperformed the national Lehman Brothers Municipal Bond Index for the period. The Fund also slightly underperformed the Lipper California Municipal Debt Funds Index. One of our primary strategies in managing the Fund was a cautious approach to credit allocations. The Portfolio's exposure to uninsured California General Obligations was underweighted relative to the Lehman Brothers Municipal Bond Index. These bonds were affected by the state's fiscal problems and underperformed. The Fund emphasized "AAA" rated insured bonds, which 2 <Page> capitalized on this investor preference. The Fund also benefited from refunding activity. Several holdings were refunded by issuers, who refinanced their debt to take advantage of the available lower interest costs. Refunding had the effect of increasing the bonds' prices and was a positive contributor to performance. Not all of the Fund's strategies were as successful. The Fund's duration (a measure of interest rate sensitivity) was positioned shorter than its benchmark to limit interest rate volatility. While this approach proved beneficial when rates jumped in the summer of 2003, it limited upside performance in the first half of the year when rates declined.

ORGANIZATION AND ACCOUNTING POLICIES Morgan Stanley California Tax-Free Income Fund (the "Fund") is registered under the Investment Company Act of 1940, as amended (the "Act"), as a diversified, open-end management investment company. The Fund's investment objective is to provide a high level of current income which is exempt from federal and California income tax, consistent with the preservation of capital. The Fund was organized as a Massachusetts business trust on April 9, 1984 and commenced operations on July 11, 1984. On July 28, 1997, the Fund converted to a multiple class share structure. The Fund offers Class A shares, Class B shares, Class C shares and Class D shares. The four classes are substantially the same except that most Class A shares are subject to a sales charge imposed at the time of purchase and some Class A shares, and most Class B shares and Class C shares are subject to a contingent deferred sales charge imposed on shares redeemed within one year, six years and one year, respectively. Class D shares are not subject to a sales charge. Additionally, Class A shares, Class B shares and Class C shares incur distribution expenses. 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. 16 <Page> C. MULTIPLE CLASS ALLOCATIONS -- Investment income, expenses (other than distribution fees), and realized and unrealized gains and losses are allocated to each class of shares based upon the relative net asset value on the date such items are recognized. Distribution fees are charged directly to the respective class. D. 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 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. E. 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. F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends and distributions to shareholders are recorded on the ex-dividend date. G. 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 MANAGEMENT AGREEMENT Pursuant to an Investment Management Agreement with Morgan Stanley Investment Advisors Inc. (the "Investment Manager") the Fund pays the Investment Manager a management fee, accrued daily and payable monthly, by applying the following annual rates to the Fund's net assets determined as of the close of each business day: 0.55% to the portion of daily net assets not exceeding $500 million; 0.525% to the portion of daily net assets exceeding $500 million but not exceeding $750 million; 0.50% to the portion of daily net assets exceeding $750 million but not exceeding $1 billion; 0.475% to the portion of daily net assets exceeding $1 billion but not exceeding $1.25 billion; and 0.45% to the portion of daily net assets in excess of $1.25 billion. 17 <Page> 3. PLAN OF DISTRIBUTION Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the "Distributor"), an affiliate of the Investment Manager. The Fund has adopted a Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act. The Plan provides that the Fund will pay the Distributor a fee which is accrued daily and paid monthly at the following annual rates: (i) Class A -- up to 0.25% of the average daily net assets of Class A; (ii) Class B -- 0.75% of the lesser of: (a) the average daily aggregate gross sales of the Class B shares since the inception of the Fund (not including reinvestment of dividend or capital gain distributions) less the average daily aggregate net asset value of the Class B shares redeemed since the Fund's inception upon which a contingent deferred sales charge has been imposed or waived; or (b) the average daily net assets of Class B; and (iii) Class C -- up to 0.75% of the average daily net assets of Class C. In the case of Class B shares, provided that the Plan continues in effect, any cumulative expenses incurred by the Distributor but not yet recovered may be recovered through the payment of future distribution fees from the Fund pursuant to the Plan and contingent deferred sales charges paid by investors upon redemption of Class B shares. Although there is no legal obligation for the Fund to pay expenses incurred in excess of payments made to the Distributor under the Plan and the proceeds of contingent deferred sales charges paid by investors upon redemption of shares, if for any reason the Plan is terminated, the Trustees will consider at that time the manner in which to treat such expenses. The Distributor has advised the Fund that there were no excess expenses as of December 31, 2003. For the year ended December 31, 2003, the Distributor rebated a portion of the distribution fees paid by the Fund on Class B shares in the amount of $3,299,473. In the case of Class A shares and Class C shares, expenses incurred pursuant to the Plan in any calendar year in excess of 0.25% or 0.75% of the average daily net assets of Class A or Class C, respectively, will not be reimbursed by the Fund through payments in any subsequent year, except that expenses representing a gross sales credit to Morgan Stanley Financial Advisors or other selected broker-dealer representatives may be reimbursed in the subsequent calendar year. For the year ended December 31, 2003, the distribution fee was accrued for Class A shares and Class C shares at the annual rate of 0.18% and 0.75%, respectively. The Distributor has informed the Fund that for the year ended December 31, 2003, it received contingent deferred sales charges from certain redemptions of the Fund's Class B shares and Class C shares of $512,813 and $16,968, respectively and received $118,071 in front-end sales charges from sales of the Fund's Class A shares. The respective shareholders pay such charges which are not an expense of the Fund. 18 <Page> 4. 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 December 31, 2003 aggregated $80,879,115 and $147,314,721, respectively. Included in aforementioned transactions are purchases of $9,428,920 and sales of $25,217,211 with other Morgan Stanley funds including net realized gain of $1,288,443. Morgan Stanley Trust, an affiliate of the Investment Manager and Distributor, is the Fund's transfer agent. At December 31, 2003, the Fund had transfer agent fees and expenses payable of approximately $5,500. 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 compensation. Aggregate pension costs for the year ended December 31, 2003 included in Trustees' fees and expenses in the Statement of Operations amounted to $7,268. At December 31, 2003, the Fund had an accrued pension liability of $60,393 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. 5. EXPENSE OFFSET The expense offset represents a reduction of the custodian fees for earnings on cash balances maintained by the Fund. 6. RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS The Fund may invest a portion of its assets in 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. 19 <Page> 7.

These complaints generally allege 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 steer investors to the funds advised by the Investment Manager or its affiliates 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 alleged efforts to steer investors to these funds. The complaints seek, among other things, unspecified compensatory 20 <Page> damages, rescissionary damages, fees and costs. The defendants intend to move to dismiss these actions and otherwise vigorously to defend them. While the Fund believes that it has meritorious defenses, the ultimate outcome of these matters 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 these matters. 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. The tax character of distributions paid was as follows: <Table> <Caption> FOR THE YEAR FOR THE YEAR ENDED ENDED DECEMBER 31, 2003 DECEMBER 31, 2002 ----------------- ----------------- Tax-exempt income $ 32,233,100 $ 35,754,993 Long-term capital gains 4,824,460 6,487,398 ----------------- ----------------- Total distributions $ 37,057,560 $ 42,242,391 ================= ================= </Table> As of December 31, 2003, the tax-basis components of accumulated earnings were as follows: <Table> Undistributed tax-exempt income $ 79,720 Undistributed long-term gains 79,588 ----------------- Net accumulated earnings 159,308 Temporary differences (60,393) Net unrealized appreciation 52,430,084 ----------------- Total accumulated earnings $ 52,528,999 ================= </Table> As of December 31, 2003, the Fund had temporary book/tax differences primarily attributable to capital loss deferrals on wash sales 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, accumulated undistributed net investment income was charged $128,530, paid-in-capital was credited $24,324 and accumulated net realized loss was credited $104,206. 21 <Page> MORGAN STANLEY CALIFORNIA TAX-FREE INCOME FUND FINANCIAL HIGHLIGHTS Selected ratios and per share data for a share of beneficial interest outstanding throughout each period: <Table> <Caption> FOR THE YEAR ENDED DECEMBER 31, ------------------------------------------------------------------ 2003 2002 2001 2000 1999 ---------- ---------- ---------- ---------- ---------- CLASS A SHARES SELECTED PER SHARE DATA: Net asset value, beginning of period $ 12.68 $ 12.34 $ 12.49 $ 11.67 $ 12.75 ---------- ---------- ---------- ---------- ---------- Income (loss) from investment operations: Net investment income 0.55 0.57 0.57 0.58 0.58 Net realized and unrealized gain (loss) (0.01) 0.44 (0.10) 0.82 (1.06) ---------- ---------- ---------- ---------- ---------- Total income (loss) from investment operations 0.54 1.01 0.47 1.40 (0.48) ---------- ---------- ---------- ---------- ---------- Less dividends and distributions from: Net investment income (0.55) (0.57) (0.58) (0.58) (0.58) Net realized gain (0.09) (0.10) (0.04) - (0.02) ---------- ---------- ---------- ---------- ---------- Total dividends and distributions (0.64) (0.67) (0.62) (0.58) (0.60) ---------- ---------- ---------- ---------- ---------- Net asset value, end of period $ 12.58 $ 12.68 $ 12.34 $ 12.49 $ 11.67 ========== ========== ========== ========== ========== TOTAL RETURN+ 4.31% 8.37% 3.90% 12.17% (3.91)% RATIOS TO AVERAGE NET ASSETS(1): Expenses (before expense offset) 0.78% 0.80% 0.80% 0.83% 0.78%(2) Net investment income 4.34% 4.53% 4.62% 4.80% 4.70% SUPPLEMENTAL DATA: Net assets, end of period, in thousands $ 17,422 $ 20,775 $ 17,147 $ 12,336 $ 6,253 Portfolio turnover rate 11% 12% 13% 4% 5% </Table> - ---------- + DOES NOT REFLECT THE DEDUCTION OF SALES CHARGE.

An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2003, by correspondence with the custodian. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Morgan Stanley California Tax-Free Income Fund as of December 31, 2003, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

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. <Page> 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 <Page> 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. <Page> 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. <Page> 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.

(f) Not applicable. (g) See table above.
