PLEASE SEE THE PROSPECTUS FOR MORE COMPLETE INFORMATION ON INVESTMENT RISKS. <Page> FUND REPORT FOR THE YEAR ENDED JUNE 30, 2006 MARKET CONDITIONS During the 12-month period ended June 30, 2006, the economy continued to show overall solid growth, despite sustained high energy prices, the Gulf Coast hurricanes, and signs of weakness in the housing market. The stock market gained most of the period, employment data was positive, inflation remained in check and consumer confidence and spending kept on course. Interest rates continued to climb as the Federal Open Market Committee (the "Fed") raised the federal funds target rate eight times during the period to 5.25 percent. The last increase, implemented on June 29, was the seventeenth consecutive rate increase, leading to market speculation about how much longer the Fed would continue its two-year tightening cycle. As of the end of the reporting period, the federal funds futures market was pricing in one additional rate increase in August. In this environment of rising interest rates, yields on municipal money-market securities generally rose as well. Although yields fluctuated early in the period and dipped slightly in the first quarter of this year due mainly to seasonal factors, they spiked sharply in the second quarter to the extent that tax-free variable-rate money-market instruments outperformed treasuries on a relative basis. These attractive yields spurred investor demand, drawing significant inflows into the market, some of which represented "crossover" investments from the taxable market. The supply of municipal money-market securities rose in the latter half of 2005, but waned early this year and as of the end of the reporting period remained 20 to 30 percent below last year's levels. State and local municipalities have had less incentive to borrow, given consistently rising interest rates and the fact that many issuing entities found themselves flush with cash from increased tax receipts. PERFORMANCE ANALYSIS As of June 30, 2006, Active Assets Tax-Free Trust had net assets of approximately $4.6 billion and an average portfolio maturity of 18 days. For the 12-month period ended June 30, 2006, the Fund provided a total return of 2.53 percent. For the seven-day period ended June 30, 2006, the Fund provided an effective annualized yield of 3.47 percent and a current yield of 3.42 percent, while its 30-day moving average yield for June was 3.17 percent. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. In anticipation of ongoing interest-rate increases, we focused on securities from segments of the market that were most responsive to (rather than hurt by) upward shifts in rates. In particular, we emphasized daily and weekly variable-rate securities. In doing so, we were able to quickly capitalize on rising yields and enhance the Fund's return while reducing its vulnerability to falling prices on longer, fixed-rate instruments. Increased fund inflows during the reporting period further enabled this strategy. As of the end of the reporting period, less than one percent of the portfolio's assets were invested in securities with maturities of greater than six months. As a result, the Fund's weighted average maturity fell over the period to 18 days. The Fund was not, however, exclusively invested in floating-rate instruments. We did selectively invest the fund assets in one- to three-month commercial paper and three- to six-month notes when the opportunity arose to lock in what we believe were attractive yields, 2 <Page> while generally avoiding investments with longer, nine- to 12-month maturities. Fund inflows also afforded us the opportunity to enhance the Fund's diversification. We were able to broaden our scope of investments, reaching out to more areas of the country. The Fund was not overweighted in any particular state, however, and contained no investments in the New Orleans area. We continued our research-intensive approach, selectively choosing for the fund only those securities that we believed would potentially add value while still meeting our conservative, risk-conscious criteria.

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 01/01/06 - 06/30/06. 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. 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 that have transactional costs, such as sales charges (loads), and redemption fees, or exchange fees. <Table> <Caption> BEGINNING ENDING EXPENSES PAID ACCOUNT VALUE ACCOUNT VALUE DURING PERIOD * ------------- ------------- --------------- 01/01/06 - 01/01/06 06/30/06 06/30/06 ------------- ------------- --------------- Actual (1.42% return) $1,000.00 $1,014.20 $2.31 Hypothetical (5% annual return before expenses) $1,000.00 $1,022.64 $2.32 </Table> - ---------- * EXPENSES ARE EQUAL TO THE FUND'S ANNUALIZED EXPENSE RATIO OF 0.46% MULTIPLIED BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY 182**/365 (TO REFLECT THE ONE-HALF YEAR PERIOD). ** ADJUSTED TO REFLECT NON-BUSINESS DAY ACCRUAL. 5 <Page> INVESTMENT ADVISORY AGREEMENT APPROVAL NATURE, EXTENT AND QUALITY OF SERVICES The Board reviewed and considered the nature and extent of the investment advisory services provided by the Investment Adviser under the Advisory Agreement, including portfolio management, investment research and fixed income securities trading. The Board also reviewed and considered the nature and extent of the non-advisory, administrative services provided by the Fund's Administrator under the Administration Agreement, including accounting, clerical, bookkeeping, compliance, business management and planning, and the provision of supplies, office space and utilities at the Investment Adviser's expense. (The Investment Adviser and the Administrator together are referred to as the "Adviser" and the Advisory and Administration Agreements together are referred to as the "Management Agreement.") The Board also compared the nature of the services provided by the Adviser with similar services provided by non-affiliated advisers as reported to the Board by Lipper Inc. ("Lipper"). The Board reviewed and considered the qualifications of the portfolio managers, the senior administrative managers and other key personnel of the Adviser who provide the advisory and administrative services to the Fund. The Board determined that the Adviser's portfolio managers and key personnel are well qualified by education and/or training and experience to perform the services in an efficient and professional manner. The Board concluded that the nature and extent of the advisory and administrative services provided were necessary and appropriate for the conduct of the business and investment activities of the Fund. The Board also concluded that the overall quality of the advisory and administrative services was satisfactory. PERFORMANCE RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS On a regular basis, the Board reviews the performance of all funds in the Morgan Stanley Fund Complex, including the Fund, compared to their peers, paying specific attention to the underperforming funds. In addition, the Board specifically reviewed the Fund's performance for the one-, three- and five-year periods ended November 30, 2005, as shown in a report provided by Lipper (the "Lipper Report"), compared to the performance of comparable funds selected by Lipper (the "performance peer group"). The Board also discussed with the Adviser the performance goals and the actual results achieved in managing the Fund. The Board concluded that the Fund's performance was competitive with that of its performance peer group. FEES RELATIVE TO OTHER PROPRIETARY FUNDS MANAGED BY THE ADVISER WITH COMPARABLE INVESTMENT STRATEGIES The Board reviewed the advisory and administrative fee (together, the "management fee") rate paid by the Fund under the Management Agreement. The Board noted that the management fee rate was comparable to the management fee rates charged by the Adviser to other proprietary funds it manages with investment strategies comparable to those of the Fund taking into account the scope of the services provided. 6 <Page> FEES AND EXPENSES RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS The Board reviewed the management fee rate and total expense ratio of the Fund as compared to the average management fee rate and average total expense ratio for funds, selected by Lipper (the "expense peer group"), managed by other advisers with investment strategies comparable to those of the Fund, as shown in the Lipper Report. The Board concluded that the Fund's management fee rate and total expense ratio were competitive with those of its expense peer group. BREAKPOINTS AND ECONOMIES OF SCALE The Board reviewed the structure of the Fund's management fee schedule under the Management Agreement and noted that it includes breakpoints. The Board also reviewed the level of the Fund's management fee and noted that the fee, as a percentage of the Fund's net assets, would decrease as net assets increase because the management fee includes breakpoints. The Board concluded that the Fund's management fee would reflect economies of scale as assets increase. PROFITABILITY OF THE ADVISER AND AFFILIATES The Board considered information concerning the costs incurred and profits realized by the Adviser and affiliates during the last year from their relationship with the Fund and during the last two years from their relationship with the Morgan Stanley Fund Complex and reviewed with the Adviser the cost allocation methodology used to determine the profitability of the Adviser and affiliates. Based on its review of the information it received, the Board concluded that the profits earned by the Adviser and affiliates were not excessive in light of the advisory, administrative and other services provided to the Fund. FALL-OUT BENEFITS The Board considered so-called "fall-out benefits" derived by the Adviser and affiliates from their relationship with the Fund and the Morgan Stanley Fund Complex, such as "float" benefits derived from handling of checks for purchases and sales of Fund shares, through a broker-dealer affiliate of the Adviser. The Board also considered that a broker-dealer affiliate of the Adviser receives from the Fund 12b-1 fees for distribution and shareholder services. The Board concluded that the float benefits were relatively small and the 12b-1 fees were competitive with those of other broker-dealers. SOFT DOLLAR BENEFITS The Board considered whether the Adviser realizes any benefits from commissions paid to brokers who execute securities transactions for the Fund ("soft dollars"). The Board noted that the Fund invests only in fixed income securities, which do not generate soft dollars. 7 <Page> ADVISER FINANCIALLY SOUND AND FINANCIALLY CAPABLE OF MEETING THE FUND'S NEEDS The Board considered whether the Adviser is financially sound and has the resources necessary to perform its obligations under the Management Agreement. The Board noted that the Adviser's operations remain profitable, although increased expenses in recent years have reduced the Adviser's profitability. The Board concluded that the Adviser has the financial resources necessary to fulfill its obligations under the Management Agreement. HISTORICAL RELATIONSHIP BETWEEN THE FUND AND THE ADVISER The Board also reviewed and considered the historical relationship between the Fund and the Adviser, including the organizational structure of the Adviser, the policies and procedures formulated and adopted by the Adviser for managing the Fund's operations and the Board's confidence in the competence and integrity of the senior managers and key personnel of the Adviser. The Board concluded that it is beneficial for the Fund to continue its relationship with the Adviser. OTHER FACTORS AND CURRENT TRENDS The Board considered the controls and procedures adopted and implemented by the Adviser and monitored by the Fund's Chief Compliance Officer and concluded that the conduct of business by the Adviser indicates a good faith effort on its part to adhere to high ethical standards in the conduct of the Fund's business. GENERAL CONCLUSION After considering and weighing all of the above factors, the Board concluded that it would be in the best interest of the Fund and its shareholders to approve renewal of the Management Agreement for another year. 8 <Page> Active Assets Tax-free Trust PORTFOLIO OF INVESTMENTS -

ORGANIZATION AND ACCOUNTING POLICIES Active Assets Tax-Free Trust (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 as high a level of daily income exempt from federal income tax as is consistent with stability of principal and liquidity. The Fund was organized as a Massachusetts business trust on March 30, 1981 and commenced operations on July 7, 1981. The following is a summary of significant accounting policies: A. VALUATION OF INVESTMENTS -- Portfolio securities are valued at amortized cost, which approximates market value, in accordance with Rule 2a-7 under the Act. 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. 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. D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and distributions to shareholders as of the close of each business day. E. 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 net assets of the Fund determined as of the close of each business day: 0.45% to the portion of the daily net assets not exceeding $500 million; 0.375% to the portion of the daily net assets exceeding $500 million but not exceeding $750 million; 0.325% to the portion of the daily net assets exceeding $750 million but not exceeding $1 billion; 0.30% to the portion of the daily net assets exceeding $1 billion but not exceeding $1.5 billion; 0.275% to the portion of the daily net assets exceeding $1.5 billion but not exceeding $2 billion; 0.25% to the portion of the daily net assets exceeding $2 billion but not exceeding $2.5 billion; 0.225% to the portion of the daily net assets exceeding $2.5 billion but not exceeding $3 billion; 0.20% to the portion of the daily net assets exceeding $3 billion but not exceeding $15 billion; and 0.199% to the portion of the daily net assets exceeding $15 billion. 25 <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 0.05% to the Fund's daily net assets. 3. PLAN OF DISTRIBUTION Morgan Stanley Distributors Inc. (the "Distributor"), an affiliate of the Investment Adviser and Administrator, is the distributor of the Fund's shares and in accordance with a Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act, finances certain expenses in connection with the promotion of sales of Fund shares. Reimbursements for these expenses are made in monthly payments by the Fund to the Distributor, which will in no event exceed an amount equal to a payment at the annual rate of 0.15% of the Fund's average daily net assets during the month. Expenses incurred by the Distributor pursuant to the Plan in any fiscal year will not be reimbursed by the Fund through payments accrued in any subsequent fiscal year. For the year ended June 30, 2006, the distribution fee was accrued at the annual rate of 0.10%. 4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES The cost of purchases and proceeds from sales/maturities of portfolio securities for the year ended June 30, 2006, aggregated $12,947,016,751 and $11,166,783,862, respectively. 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 June 30, 2006, included in Trustees' fees and expenses in the Statement of Operations amounted to $7,377. At June 30, 2006, the Fund had an accrued pension liability of $62,580 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 26 <Page> 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. SHARES OF BENEFICIAL INTEREST Transactions in shares of beneficial interest, at $1.00 per share, were as follows: <Table> <Caption> FOR THE YEAR FOR THE YEAR ENDED ENDED JUNE 30, 2006 JUNE 30, 2005 ---------------- ---------------- Shares sold $ 21,066,195,217 $ 11,647,980,944 Shares issued in reinvestment of dividends 102,563,944 38,652,509 ---------------- ---------------- 21,168,759,161 11,686,633,453 Shares redeemed (19,388,245,856) (11,687,713,857) ---------------- ---------------- Net increase (decrease) in shares outstanding $ 1,780,513,305 $ (1,080,404) ================ ================ </Table> 6. EXPENSE OFFSET The expense offset represents a reduction of custodian and transfer agent fees and expenses for earnings on cash balances maintained by the Fund. 7. FEDERAL INCOME TAX STATUS As of June 30, 2006, 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 permanent book/tax differences attributable to ordinary income and capital gain retained by the Fund and nondeductible expenses. To reflect reclassifications arising from the permanent differences, accumulated net realized loss was charged $63, accumulated undistributed net investment income was charged $70 and paid-in-capital was credited $133. 8. 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 27 <Page> 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. On March 9, 2005, Plaintiffs sought leave to supplement their complaint to assert claims on behalf of other investors, which motion defendants opposed. On April 14, 2006, the Court granted defendants' motion to dismiss in its entirety. Additionally, the Court denied Plaintiff's motion to supplement their complaint. This matter is now concluded. 9. NEW ACCOUNTING PRONOUNCEMENT In July 2006, the Financial Accounting Standards Board (FASB) issued Interpretation 48, Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position must meet before being recognized in the financial statements. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Fund will adopt FIN 48 during 2007 and the impact to the Fund's financial statements, if any, is currently being assessed. 28 <Page> Active Assets Tax-Free Trust FINANCIAL HIGHLIGHTS Selected ratios and per share data for a share of beneficial interest outstanding throughout each period: <Table> <Caption> FOR THE YEAR ENDED JUNE 30, ----------------------------------------------- 2006 2005 2004 2003 2002 ------- ------- ------- ------- ------- Selected Per Share Data: Net asset value, beginning of period $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 ------- ------- ------- ------- ------- Net income from investment operations 0.025 0.013 0.005 0.008 0.014 Less dividends from net investment income (0.025) (0.013) (0.005) (0.008) (0.014) ------- ------- ------- ------- ------- Net asset value, end of period $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 ======= ======= ======= ======= ======= Total Return 2.53% 1.32% 0.50% 0.81% 1.38% Ratios to Average Net Assets: Total expenses (before expense offset) 0.47% 0.49% 0.48% 0.48% 0.48%(1) Net investment income 2.57% 1.30% 0.50% 0.80% 1.38% Supplemental Data: Net assets, end of period, in millions $ 4,637 $ 2,857 $ 2,858 $ 3,116 $ 2,947 </Table> - ---------- (1) DOES NOT REFLECT THE EFFECT OF EXPENSE OFFSET OF 0.01%. SEE NOTES TO FINANCIAL STATEMENTS 29 <Page> Active Assets Tax-Free Trust REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and Board of Trustees of Active Assets Tax-Free Trust: We have audited the accompanying statement of assets and liabilities of Active Assets Tax-Free Trust (the "Fund"), including the portfolio of investments, as of June 30, 2006, 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 June 30, 2006, by correspondence with the custodian. 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 Active Assets Tax-Free Trust as of June 30, 2006, 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.
