BECAUSE CLASS B SHARES INCURRED LOWER EXPENSES UNDER THE 12b-1 PLAN THAN DID CLASS A SHARES FOR THE FISCAL PERIOD ENDED DECEMBER 31, 2005, THE TOTAL OPERATING EXPENSE RATIO FOR CLASS B SHARES WAS LOWER AND, AS A RESULT, THE PERFORMANCE OF CLASS B SHARES WAS HIGHER THAN THAT OF THE CLASS A SHARES. THERE CAN BE NO ASSURANCE THAT THIS WILL CONTINUE TO OCCUR IN THE FUTURE AS THE MAXIMUM FEES PAYABLE BY CLASS B SHARES UNDER THE 12b-1 PLAN ARE HIGHER THAN THOSE PAYABLE BY CLASS A SHARES. MARKET CONDITIONS Economic reports continued to show moderate growth in 2005, sustained by consumer spending and reasonable gains in employment. Core inflation (which excludes food and energy) remained benign, but protracted high oil prices fostered inflationary concerns, particularly during the summer. The unprecedented devastation caused by Hurricanes Rita and Katrina in September heightened the market's uncertainty. While the immediate economic impact was a major disruption of the nation's energy infrastructure, the economy showed considerable resilience in the fourth quarter. In fact, the consensus view developed that accelerated reconstruction in storm-ravaged areas would serve as a stimulus to future economic growth. Throughout the year, the Federal Open Market Committee (the "Fed") continued the rate tightening pattern that began in June of 2004 and raised the federal funds target rate eight times in 25 basis point (0.25 percentage points) increments. As a result, the rate increased from 2.25 percent to 4.25 percent. Yields on short-term municipal bonds followed the target rate during 2005 and rose steadily. In contrast, long-term bond yields were little changed for the period overall, reflecting strong demand for longer maturity bonds and the market's perception that the Fed was controlling inflation pressures. The slope of the yield curve flattened as the difference between short-term and long-term interest rates narrowed substantially. Representative yields on 30-year AAA rated municipal bonds ranged from a low of 4.20 percent in June to a high of 4.65 percent in November. At the end of December, the yield stood at 4.40 percent. Investors' quest for yield favored lower-quality bonds over high-grade issues and kept credit spreads relatively tight. (Credit spreads measure the added compensation investors require to assume additional credit risk. When credit spreads tighten, lower-rated issues typically outperform.) Long-term municipal volume increased 13 percent to a record $408 billion in 2005. The flatter yield curve and 2 <Page> low long-term interest rates encouraged municipalities to refinance their debt. Such refundings accounted for 30 percent of annual volume, nearly a 50 percent increase over 2004. California was the leading issuer of debt and accounted for 14 percent of volume in 2005. The municipal-to-Treasury yield ratio, which gauges the performance between the two markets, remained attractive for tax-exempt bonds. During the year, the ratio of 10-year municipals to 10-year Treasuries averaged 86 percent and the 30-year ratio averaged 97 percent. (The higher the ratio, the greater the attractiveness of municipal yields relative to Treasury yields.) As a result, institutional investors -- such as hedge funds and arbitrage accounts -- that normally focus on taxable bond sectors "crossed-over" to purchase municipal bonds. Demand from individual investors was less robust, given the low absolute level of yields. The State of California enjoyed improving economic, fiscal and credit conditions throughout the period. Unemployment declined and the defense and high technology sectors experienced steady growth. These economic improvements helped to boost stronger state revenues. California also made progress in resolving some of its structural budget imbalances, spurring further investor interest in its municipal debt market. PERFORMANCE ANALYSIS Morgan Stanley California Tax-Free Income Fund Class B and D shares underperformed the Lehman Brothers California Exempt Index, outperformed the Lehman Brothers Municipal Bond Index and underperformed the Lipper California Municipal Debt Funds Index for the 12 months ended December 31, 2005, assuming no deduction of applicable sales charges. Class A and C shares underperformed each index for the same time period, assuming no deduction of applicable sales charges. In anticipation of Fed tightenings and generally higher interest rates, the Fund made modest ongoing adjustments to its long-term portfolio to reduce volatility. For example, the Fund's interest-rate sensitivity was positioned conservatively. At the close of the period, the Fund's option-adjusted duration* was 6.6 years. The Fund used proceeds from the sale of refunded issues to purchase premium coupon bonds with defensive characteristics. Overall, the Fund maintained a high average credit quality with over 85 percent of the bonds in its portfolio rated A or higher, at the close of the period. The Fund reduced exposure to insured AAA holdings and increased exposure to investment-grade credits rated A and BBB. Reflecting a commitment to diversification, the Fund's net assets of approximately $569 million were invested among 13 long-term sectors and 71 credits. * 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-INTEREST-RATE ENVIRONMENTS, WHILE FUNDS WITH LONGER DURATIONS PERFORM BETTER WHEN RATES DECLINE.

SEE THE FUND'S CURRENT PROSPECTUS FOR COMPLETE DETAILS ON FEES AND SALES CHARGES. ++ ENDING VALUE ASSUMING A COMPLETE REDEMPTION ON DECEMBER 31, 2005. 9 <Page> EXPENSE EXAMPLE As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemption fees; and (2) ongoing costs, including advisory fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period 07/01/05 - 12/31/05. ACTUAL EXPENSES The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line of the table below provides information about hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) and redemption fees. Therefore, the second line of the table is useful in comparing ongoing costs, and will not help you determine the relative total cost of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING PERIOD * ------------- ------------- --------------- 07/01/05 - 07/01/05 12/31/05 12/31/05 ------------- ------------- --------------- CLASS A Actual (0.57% return) $ 1,000.00 $ 1,005.70 $ 4.35 Hypothetical (5% annual return before expenses) $ 1,000.00 $ 1,020.87 $ 4.38 CLASS B Actual (0.74% return) $ 1,000.00 $ 1,007.40 $ 3.59 Hypothetical (5% annual return before expenses) $ 1,000.00 $ 1,021.63 $ 3.62 CLASS C Actual (0.32% return) $ 1,000.00 $ 1,003.20 $ 6.87 Hypothetical (5% annual return before expenses) $ 1,000.00 $ 1,018.35 $ 6.92 CLASS D Actual (0.78% return) $ 1,000.00 $ 1,007.80 $ 3.09 Hypothetical (5% annual return before expenses) $ 1,000.00 $ 1,022.13 $ 3.11 </Table> - ---------- * EXPENSES ARE EQUAL TO THE FUND'S ANNUALIZED EXPENSE RATIO OF 0.86%, 0.71%, 1.36% AND 0.61% FOR CLASS A, CLASS B, CLASS C AND CLASS D SHARES, RESPECTIVELY, MULTIPLIED BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY 184/365 (TO REFLECT THE ONE-HALF YEAR PERIOD).

STATEMENTS - DECEMBER 31, 2005 1. 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 eighteen months, 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. Effective August 29, 2005, the Board of Trustees of the Fund approved the implementation of a 2% redemption fee on Class A shares, Class B shares, Class C shares, and Class D shares, which is paid directly to the Fund, for shares redeemed within seven days of purchase. The redemption fee is designed to protect the Fund and its remaining shareholders from the effects of short-term trading. 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. 19 <Page> 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. 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 ADVISORY/ADMINISTRATION AGREEMENTS Pursuant to an Investment Advisory Agreement with Morgan Stanley Investment Advisors Inc. (the "Investment Adviser") the Fund pays the Investment Adviser an advisory 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: 0.47% to the portion of the daily net assets not exceeding $500 million; 0.445% to the portion of the daily net assets exceeding $500 million but not exceeding $750 million; 0.42% to the portion of the daily net assets exceeding $750 million but not exceeding $1 billion; 0.395% to the portion of the daily net assets exceeding $1 billion but not exceeding $1.25 billion; and 0.37% to the portion of the daily net assets in excess of $1.25 billion. 20 <Page> Pursuant to an Administration Agreement with Morgan Stanley Services Company Inc. (the "Administrator"), an affiliate of the Investment Adviser, the Fund pays an administration fee, accrued daily and payable monthly, by applying the annual rate of 0.08% to the Fund's daily net assets. Effective June 1, 2005, the Investment Adviser has agreed to cap the Fund's operating expenses (except for brokerage and 12b-1 fees) by assuming the Fund's "other expenses" and/or waiving the Fund's advisory fees, and the Administrator has agreed to waive the Fund's administrative fees, to the extent such operating expenses exceed 0.60% of the average daily net assets of the Fund on an annualized basis. These voluntary assumptions/waivers may be discontinued at any time. 3. PLAN OF DISTRIBUTION Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the "Distributor"), an affiliate of the Investment Adviser and Administrator. 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 -- up to 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 expenses as of December 31, 2005. For the year ended December 31, 2005, the distribution fee was accrued for Class B shares at the annual rate of 0.07%. At December 31, 2005, included in the Statement of Assets and Liabilities, is a receivable from affiliate, which represents payments due from the Distributor to the Fund. 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, 2005, the distribution fee was accrued for Class A shares and Class C shares at the annual rate of 0.25% and 0.75%, respectively. 21 <Page> The Distributor has informed the Fund that for the year ended December 31, 2005, it received contingent deferred sales charges from certain redemptions of the Fund's Class B shares and Class C shares of $219,136 and $1,023, respectively and received $129,324 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. 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, 2005 aggregated $133,266,051 and $179,562,297, respectively. Included in the aforementioned transactions is a purchase of $5,416,400 and a sale of $5,343,350 with another Morgan Stanley fund including net realized gain of $443,891. Morgan Stanley Trust, an affiliate of the Investment Adviser, Administrator and Distributor, is the Fund's transfer agent. 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. The Trustees voted to close the plan to new participants and eliminate the future benefits growth due to increases to compensation after July 31, 2003. Aggregate pension costs for the year ended December 31, 2005 included in Trustees' fees and expenses in the Statement of Operations amounted to $7,384. At December 31, 2005, the Fund had an accrued pension liability of $63,399 which is included in accrued expenses in the Statement of Assets and Liabilities. The Fund 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 Fund. 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 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. 22 <Page> 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. 7.

LEGAL MATTERS The Investment Adviser, certain affiliates of the Investment Adviser, certain officers of such affiliates and certain investment companies advised by the Investment Adviser or its affiliates, including the Fund, are named as defendants in a consolidated class action. This consolidated action also names as defendants certain individual Trustees and Directors of the Morgan Stanley funds. The consolidated amended complaint, filed in the United States District Court Southern District of New York on April 16, 2004, generally alleges that defendants, including the Fund, violated their statutory disclosure obligations and fiduciary duties by failing properly to disclose (i) that the Investment Adviser and certain affiliates of the Investment Adviser allegedly offered economic incentives to brokers and others to recommend the funds advised by the Investment Adviser or its affiliates to investors rather than funds managed by other companies, and (ii) that the funds advised by the Investment Adviser 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 have moved to dismiss the action and intend to otherwise vigorously defend it. On March 9, 2005, Plaintiffs sought leave to supplement their complaint to assert claims on behalf of other investors. While the Fund and Adviser believe that each has meritorious defenses, the ultimate outcome of this matter is not presently determinable at this stage of the litigation, and no provision has been made in the Fund's financial statements for the effect, if any, of this matter. 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, 2005 DECEMBER 31, 2004 ----------------- ----------------- Tax-exempt income $ 25,232,039 $ 28,687,522 Ordinary income 51,809 31,904 Long-term capital gains 9,487,096 5,343,272 ----------------- ----------------- Total distributions $ 34,770,944 $ 34,062,698 ================= ================= </Table> 24 <Page> As of December 31, 2005, the tax-basis components of accumulated earnings were as follows: <Table> Undistributed tax-exempt income $ 158,408 Undistributed long-term gains -- ------------- Net accumulated earnings 158,408 Post-October losses (148,589) Temporary differences (64,581) Net unrealized appreciation 31,801,688 ------------- Total accumulated earnings $ 31,746,926 ============= </Table> As of December 31, 2005, 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), mark-to-market of open futures contracts and book amortization of discounts on debt securities and permanent book/tax differences 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 and distributions in excess of net realized gain was credited $14,612. 25 <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, --------------------------------------------------------------------------- 2005 2004 2003 2002 2001 ----------- ----------- ----------- ----------- ----------- CLASS A SHARES SELECTED PER SHARE DATA: Net asset value, beginning of period $ 12.46 $ 12.58 $ 12.68 $ 12.34 $ 12.49 ----------- ----------- ----------- ----------- ----------- Income (loss) from investment operations: Net investment income 0.52 0.54 0.55 0.57 0.57 Net realized and unrealized gain (loss) (0.10) (0.02) (0.01) 0.44 (0.10) ----------- ----------- ----------- ----------- ----------- Total income from investment operations 0.42 0.52 0.54 1.01 0.47 ----------- ----------- ----------- ----------- ----------- Less dividends and distributions from: Net investment income (0.51) (0.53) (0.55) (0.57) (0.58) Net realized gain (0.21) (0.11) (0.09) (0.10) (0.04) ----------- ----------- ----------- ----------- ----------- Total dividends and distributions (0.72) (0.64) (0.64) (0.67) (0.62) ----------- ----------- ----------- ----------- ----------- Net asset value, end of period $ 12.16 $ 12.46 $ 12.58 $ 12.68 $ 12.34 =========== =========== =========== =========== =========== TOTAL RETURN+ 3.44% 4.26% 4.31% 8.37% 3.90% RATIOS TO AVERAGE NET ASSETS(1): Expenses (before expense offset) 0.86%(2) 0.81% 0.78% 0.80% 0.80% Net investment income 4.11%(2) 4.29% 4.34% 4.53% 4.62% SUPPLEMENTAL DATA: Net assets, end of period, in thousands $ 329,938 $ 19,203 $ 17,422 $ 20,775 $ 17,147 Portfolio turnover rate 23% 10% 11% 12% 13% </Table> - ---------- + DOES NOT REFLECT THE DEDUCTION OF SALES CHARGE.

SEE NOTES TO FINANCIAL STATEMENTS 29 <Page> MORGAN STANLEY CALIFORNIA TAX-FREE INCOME FUND REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF MORGAN STANLEY CALIFORNIA TAX-FREE INCOME FUND: We have audited the accompanying statement of assets and liabilities of Morgan Stanley California Tax-Free Income Fund (the "Fund"), including the portfolio of investments, as of December 31, 2005, and the related statements of operations for the year then ended and changes in 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. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers. 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, 2005, 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, supersedes 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 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 <Page> 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. 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 <Page> 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. 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.
