SEE PERFORMANCE SUMMARY FOR STANDARDIZED PERFORMANCE AND BENCHMARK INFORMATION. MARKET CONDITIONS The annual reporting period opened on an optimistic note. Despite high oil prices and ongoing increases to the federal funds target rate, stocks rallied through December. The market was buoyed by a variety of factors, including the undisputed presidential election, indications of steady economic growth, a pick up in merger-and-acquisition activity and initial public offerings, as well as good corporate earnings. In contrast to the strong close of 2004, the first months of 2005 were far less ebullient. Stocks retreated amid profit taking and deteriorating sentiment. Investors grew increasingly apprehensive about soaring oil prices, inflationary pressures, the Federal Open Market Committee's (the "Fed") interest rate tightenings, and the pace of economic growth. Additionally, the misfortunes of the auto industry called into question the strength of the U.S. economy. Although oil prices continued to increase, the climate brightened by late spring. Encouraging economic data, increased consumer confidence, waning inflationary fears and many solid corporate earnings announcements boosted the stock market. Against the backdrop of mixed economic data and additional increases in the federal funds rate, the markets became increasingly choppy from August through mid-October. The Gulf Coast hurricanes sent oil prices spiking and created anxiety about the economy, particularly given the Fed's resolve to continue raising rates. In mid-October, the stock market regained its equilibrium. Declining oil prices, better-than-expected economic data, the nomination of Ben Bernanke to head the Federal Reserve, and strengthening consumer trends provided a boost to investor sentiment in the final portion of October. Stocks continued to advance through November, buoyed by indications that the Fed might soon slow the pace of rate increases, a boost in consumer confidence, continued declines in oil prices, strong retail trends (excluding the auto industry), and acceptable housing data. PERFORMANCE ANALYSIS Morgan Stanley KLD Social Index Fund underperformed the KLD Large Cap Social(SM) Index* for the 12 months ended November 30, 2005, after the deduction of the Fund's fees and expenses and assuming no deduction of applicable sales charges. Class A, B and D shares outperformed and Class C shares narrowly underperformed the Lipper Large-Cap Core Funds Index for the same time period, assuming no deduction of sales charges. 2 <Page> The gains of the Fund and the Index were supported by positive performance across all 10 sectors of the Index. In terms of absolute returns, the top performing sectors were energy, healthcare and utilities. Rising commodity prices and increased demand provided support for the energy and utilities sector. Within healthcare, the equipment and services industry was particularly strong, boosted by pricing power and new plan member enrollments within healthcare services. Biotechnology and pharmaceutical stocks also contributed to the sector's gains as favorable drug trial results were well received by the market. While all the sectors generated positive performance, two industry groups landed in negative territory. The auto sector was plagued by a host of issues, including missed earnings, credit downgrades and labor problems. In the media industry, traditional companies came under increased pressure from Internet competitors for advertising revenues; stock-specific setbacks also hindered the group. Given that the KLD Large Cap Social(SM) Index is market capitalization weighted (and that the Fund seeks to replicate the performance attributes of the Index, before Fund fees), the overall contribution of each sector was influenced by its relative size within the Index and the Fund portfolio. In terms of overall contributions to returns, the healthcare, financial and technology sectors added most significantly to positive performance. As discussed previously, healthcare services, biotechnology and pharmaceuticals were among the principal drivers. Much of the contribution of the financials and technology sectors reflected their sizable weightings within the Index. That said, diversified financial services performed briskly, boosted by investment banking activity, such as mergers and acquisitions. Technology included pockets of both strength and weakness, due to company specific factors. On an industry level, media stocks slowed the pace of the Index and the Fund most significantly. On a sector basis, the telecommunications sector contributed the least to overall performance. Here, performance was hindered as the market gravitated away from companies pursuing acquisitions. From a market capitalization perspective, small cap stocks contributed the most to upside performance, while mega caps lagged. THERE IS NO GUARANTEE THAT ANY SECTORS MENTIONED WILL CONTINUE TO PERFORM WELL OR THAT SECURITIES IN SUCH SECTORS WILL BE HELD BY THE FUND IN THE FUTURE. 3 <Page> TOP 10 HOLDINGS <Table> Microsoft Corp. 3.1% Procter & Gamble Co.

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 06/01/05 - 11/30/05. 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 * ------------- ------------- --------------- 06/01/05 - 06/01/05 11/30/05 11/30/05 ------------- ------------- --------------- CLASS A Actual (7.44% return) $ 1,000.00 $ 1,074.40 $ 1.30 Hypothetical (5% annual return before expenses) $ 1,000.00 $ 1,023.82 $ 1.27 CLASS B Actual (6.97% return) $ 1,000.00 $ 1,069.70 $ 5.19 Hypothetical (5% annual return before expenses) $ 1,000.00 $ 1,020.05 $ 5.06 CLASS C Actual (7.11% return) $ 1,000.00 $ 1,071.10 $ 5.19 Hypothetical (5% annual return before expenses) $ 1,000.00 $ 1,020.05 $ 5.06 CLASS D Actual (7.53% return) $ 1,000.00 $ 1,075.30 $ 0.00 Hypothetical (5% annual return before expenses) $ 1,000.00 $ 1,025.07 $ 0.00 </Table> - ---------- * EXPENSES ARE EQUAL TO THE FUND'S ANNUALIZED EXPENSE RATIO OF 0.25%, 1.00%, 1.00% AND 0.00% FOR CLASS A, CLASS B, CLASS C AND CLASS D SHARES, RESPECTIVELY, MULTIPLIED BY THE AVERAGE ACCOUNT VALUE OVER THE PERIOD, MULTIPLIED BY 183/365 (TO REFLECT THE ONE-HALF YEAR PERIOD).

ORGANIZATION AND ACCOUNTING POLICIES Morgan Stanley KLD Social Index 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 investment results that before expenses correspond to the total return of the KLD Large Cap Social(SM) Index ("KLD Index"). The Fund was organized as a Massachusetts business trust on April 6, 2001 and commenced operations on July 13, 2001. 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) an equity portfolio security listed or traded on the New York Stock Exchange ("NYSE") or American Stock Exchange or other exchange is valued at its latest sale price prior to the time when assets are valued; if there were no sales that day, the security is valued at the mean between the last reported bid and asked price; (2) an equity portfolio security listed or traded on the Nasdaq is valued at the Nasdaq Official Closing Price; if there were no sales that day, the security is valued at the mean between the last reported bid and asked price; (3) all other portfolio securities for which over-the-counter market quotations are readily available are valued at the mean between the last reported bid and asked price. In cases where a security is traded on more than one exchange, the security is valued on the exchange designated as the primary market; (4) for equity securities traded on foreign exchanges, the last reported sale price or the latest bid price may be used if there were no sales on a particular day; (5) futures are valued at the latest price published by the commodities exchange on which they trade; (6) when market quotations are not readily available or Morgan Stanley Investment Advisors Inc. (the "Investment Adviser"), determines that the latest sale price, the bid price or the mean between the last reported bid and asked price do not reflect a security's market value, portfolio securities are valued at their fair value as determined in good faith under procedures established by and under the general supervision of the Fund's Trustees. Occasionally, developments affecting the closing prices of securities and other assets may occur between the times at which valuations of such securities are determined (that is, close of the foreign market on which the securities trade) and the 23 <Page> close of business on the NYSE. If developments occur during such periods that are expected to materially affect the value of such securities, such valuations may be adjusted to reflect the estimated fair value of such securities as of the close of the NYSE, as determined in good faith by the Fund's Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the Trustees of the Fund; and (7) 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. Dividend income and other distributions are recorded on the ex-dividend date. Discounts are accreted and premiums are amortized over the life of the respective securities. Interest income is accrued daily. C. REPURCHASE AGREEMENTS -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund, along with other affiliated entities managed by the Investment Adviser, may transfer uninvested cash balances into one or more joint repurchase agreement accounts. These balances are invested in one or more repurchase agreements and are collateralized by cash, U.S. Treasury or federal agency obligations. The Fund may also invest directly with institutions in repurchase agreements. The Fund's custodian receives the collateral, which is marked-to-market daily to determine that the value of the collateral does not decrease below the repurchase price plus accrued interest. D. 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. E. 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. 24 <Page> F. 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 income to its shareholders. Accordingly, no federal income tax provision is required. G. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends and distributions to shareholders are recorded on the ex-dividend date. H. 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, the Fund pays the Investment Adviser an advisory fee, accrued daily and payable monthly, by applying the annual rate of 0.12% to the daily net assets of the Fund determined as of the close of each business day. 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. The Investment Adviser and Administrator have agreed to waive their fees and assume all operating expenses (except for brokerage and 12b-1 fees) until such time as the Fund has $50 million of net assets or April 30, 2006, whichever occurs first. Thereafter, 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 administration fees, to the extent that such operating expenses exceed 0.40% of the average daily net assets of the Fund on an annualized basis. At November 30, 2005, included in the Statement of Assets and Liabilities is a receivable from affiliate, which represents expense reimbursements due to the Fund. 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 1.0% of the average daily net assets of Class B; and (iii) Class C -- up to 1.0% of the average daily net assets of Class C. 25 <Page> 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 such excess amounts totaled $1,057,057 at November 30, 2005. 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 1.0% 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 November 30, 2005, the distribution fee was accrued for Class A shares and Class C shares at the annual rate of 0.22% and 1.0%, respectively. The Distributor has informed the Fund that for the year ended November 30, 2005, it received contingent deferred sales charges from certain redemptions of the Fund's Class B shares and Class C shares of $23,772 and $27, respectively and received $11,107 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 November 30, 2005, aggregated $269,575 and $385,067, respectively. Morgan Stanley Trust, an affiliate of the Investment Adviser, Administrator and Distributor, is the Fund's transfer agent. 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. 26 <Page> 5.

PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS The Fund may purchase and sell stock index futures ("futures contracts") for the following reasons: to simulate full investment in the KLD Index while retaining a cash balance for fund management purposes; to facilitate trading; to reduce transaction costs; or to seek higher investment returns when a futures contract is priced more attractively than stocks comprising the KLD Index. 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 counter parties to meet the terms of their contracts. 27 <Page> 7. 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 NOVEMBER 30, 2005 NOVEMBER 30, 2004 ----------------- ----------------- Ordinary income $ 200,000 $ 82,000 ================= ================= </Table> As of November 30, 2005, the tax-basis components of accumulated losses were as follows: <Table> Undistributed ordinary income $ 194,987 Undistributed long-term gains -- ------------ Net accumulated earnings 194,987 Capital loss carryforward* (2,705,564) Net unrealized appreciation 2,294,944 ------------ Total accumulated losses $ (215,633) ============ </Table> *During the year ended November 30, 2005, the Fund utilized $162,763 of its net capital loss carryforward. As of November 30, 2005, the Fund had a net capital loss carryforward of $2,705,564 of which $1,802,343 will expire on November 30, 2010 and $903,221 will expire on November 30, 2011 to offset future capital gains to the extent provided by regulations. As of November 30, 2005, the Fund had temporary book/tax differences primarily attributable to capital loss deferrals on wash sales and mark-to-market of open futures contracts and permanent book/tax differences attributable to tax adjustments on real estate investment trusts held by the Fund. To reflect reclassifications arising from the permanent differences, accumulated undistributed net investment income was charged and accumulated net realized loss was credited $3,834. 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 28 <Page> 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. 29 <Page> MORGAN STANLEY KLD SOCIAL INDEX FUND FINANCIAL HIGHLIGHTS Selected ratios and per share data for a share of beneficial interest outstanding throughout each period: <Table> <Caption> FOR THE PERIOD FOR THE YEAR ENDED NOVEMBER 30, JULY 13, 2001* --------------------------------------------------- THROUGH 2005 2004 2003 2002 NOVEMBER 30, 2001 --------- --------- --------- --------- ------------------ CLASS A SHARES SELECTED PER SHARE DATA: Net asset value, beginning of period $ 9.75 $ 8.88 $ 7.73 $ 9.39 $ 10.00 --------- --------- --------- --------- ------------------ Income (loss) from investment operations: Net investment income++ 0.15 0.15 0.10 0.09 0.03 Net realized and unrealized gain (loss) 0.78 0.80 1.17 (1.70) (0.64) --------- --------- --------- --------- ------------------ Total income (loss) from investment operations 0.93 0.95 1.27 (1.61) (0.61) --------- --------- --------- --------- ------------------ Less dividends from net investment income (0.14) (0.08) (0.12) (0.05) - --------- --------- --------- --------- ------------------ Net asset value, end of period $ 10.54 $ 9.75 $ 8.88 $ 7.73 $ 9.39 ========= ========= ========= ========= ================== TOTAL RETURN+ 9.59% 10.81% 16.72% (17.25)% (6.10)%(1) RATIOS TO AVERAGE NET ASSETS(3)(4): Expenses 0.22% 0.23% 0.20% 0.24% 0.25%(2) Net investment income 1.49% 1.61% 1.29% 1.01% 0.85%(2) SUPPLEMENTAL DATA: Net assets, end of period, in thousands $ 4,250 $ 2,384 $ 2,103 $ 756 $ 329 Portfolio turnover rate 1% 10% 24% 13% 3%(1) </Table> - ---------- * COMMENCEMENT OF OPERATIONS. ++ THE PER SHARE AMOUNTS WERE COMPUTED USING AN AVERAGE NUMBER OF SHARES OUTSTANDING DURING THE PERIOD. + DOES NOT REFLECT THE DEDUCTION OF SALES CHARGE.

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 November 30, 2005, by correspondence with the custodian and broker. 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 KLD Social Index Fund as of November 30, 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 periods presented, 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).
