MERRILL LYNCH FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2006 A Letter From the President Dear Shareholder Financial markets began 2006 with a return to volatility following a fairly uninspiring 2005. For the six- and 12-month periods ended February 28, 2006, most major market indexes landed in positive territory: Total Returns as of February 28, 2006 6-month 12-month U.S. equities (Standard & Poor's 500 Index) + 5.93% + 8.40% Small cap U.S. equities (Russell 2000 Index) +10.24 +16.59 International equities (MSCI Europe, Australasia, Far East Index) +15.14 +17.41 Fixed income (Lehman Brothers Aggregate Bond Index) - 0.11 + 2.74 Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) + 0.99 + 3.87 High yield bonds (Credit Suisse High Yield Index) + 1.89 + 3.27 The Federal Reserve Board (the Fed) increased interest rates 200 basis points (2.00%) over the past 12 months, bringing the target federal funds rate to 4.5%. Notably, Ben Bernanke replaced Alan Greenspan as Fed chairman in January, a month after the central bank removed the critical word "measured" from the description of its rate-hiking program. Still, most observers expect at least one more interest rate hike before the Fed pauses in its tightening campaign. U.S. economic growth, which came in at 4.1% in the third quarter of 2005, fell to 1.6% in the fourth quarter. Growth is expected to reaccelerate in the first quarter of 2006, although the economy is likely to feel some pressure in the quarters ahead as the consumer sector seems to be softening. Capital spending by businesses, however, appears relatively strong. Overall corporate health, including strong company balance sheets, helped prompt robust dividend- distribution, share-buyback and merger-and-acquisition activity in 2005, a trend that has continued in 2006. This, as well as reasonably good company earnings and low core inflation, has been supportive of U.S. stocks despite the headwinds of rising interest rates and high energy prices. Many international equity markets have fared even better, thanks in part to higher economic growth rates and low inflation. In the U.S. bond market, short-term interest rates continued to move higher as longer-term interest rates advanced more moderately. After flattening dramatically in 2005, the Treasury curve recently has been toying with bouts of inversion, whereby short-term yields have surpassed long-term yields. At period-end, the six-month Treasury bill offered the highest yield on the curve at 4.74%. Amid the uncertainty inherent in the financial markets, we encourage you to review your goals periodically with your financial advisor and to make portfolio changes, as needed. For timely "food for thought" for investors, we also invite you to visit Shareholder magazine at www.mlim.ml.com/shareholdermagazine. As always, we thank you for trusting Merrill Lynch Investment Managers with your investment assets, and we look forward to continuing to serve your investment needs. Sincerely, (Robert C. Doll, Jr.) Robert C. Doll, Jr. President and Trustee MERRILL LYNCH FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2006 A Discussion With Your Fund's Portfolio Manager The Fund met its primary objective of preserving investor principal while also outpacing the average return of the Lipper Balanced Target Maturity Funds category. How did the Fund perform during the period in light of the existing market conditions? For the six-month period ended February 28, 2006, Merrill Lynch Fundamental Growth Principal Protected Fund's Class A, Class B, Class C and Class I Shares had total returns of +2.63%, +2.21%, +2.17% and +2.78%, respectively. (Fund results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 6 - 8 of this report to shareholders.) For the same period, the Fund's all-equity benchmarks, the Standard & Poor's (S&P) 500 Index and the S&P 500/Citigroup Growth Index, returned +5.93% and +3.43%, respectively. Because the Fund incorporates a fixed income component, its returns may be greater or less than those provided by the equity markets alone. The fixed income market, as measured by the Lehman Brothers Aggregate Bond Index, returned -.11% for the six-month period. Thus, the Fund's fixed income allocation produced a drag versus the all-equity benchmarks. Importantly, however, the Fund met its objective of protecting investor principal while also outpacing the +1.57% average return of the Lipper Balanced Target Maturity Funds category for the six months ended February 28, 2006. (Funds in this Lipper category invest to provide a guaranteed return of investment at maturity. Some of the assets are invested in zero-coupon U.S. Treasury securities, while the remainder is in equity securities for long-term growth of capital and income.) The equity, bond and commodity markets continued to follow a relatively unpredictable and volatile pattern during the six months ended February 28, 2006. Total returns varied among regions and sectors, with the S&P Utilities Index returning +1.83%, for example, and the Morgan Stanley Capital International Emerging Markets Latin America Index returning +41.70%. The returns of large capitalization U.S. growth stocks (as represented by the +3.43% return of the S&P 500/Citigroup Growth Index) were less than half of large cap value stock returns (as represented by the +8.48% return of the S&P 500/Citigroup Value Index) during the reporting period. Small cap and mid cap indexes also provided significantly better investment returns than their large cap counterparts. We are pleased with the performance of the actively managed equity portfolio in what was a challenging period for large cap growth investing. Within the equity portfolio, performance benefited most from favorable stock selection in the underweighted consumer discretionary sector, where top performers included Starbucks Corp., Wynn Resorts Ltd., Staples Inc., Walt Disney Co., Nike, Inc. and Coach, Inc. A continuing positive for more than three years has been our investment holdings in the overweighted energy sector. The major contributors during this six-month period were repeat winners such as Schlumberger Ltd., Transocean, Inc., Baker Hughes, Inc. and Halliburton Co. Investments in the industrials sector also aided performance, led by our positions in Caterpillar, Inc., Lockheed Martin Corp., 3M Co., MSC Industrial Direct Co., General Electric Co., Fluor Corp. and Boeing Co. In the materials sector, our positions in Air Products & Chemicals Inc., Praxair, Inc. and E.I. DuPont de Nemours & Co. benefited performance. The leading emerging economies in Asia have industrial development programs that require enormous amounts of the products and services offered by these companies. Detracting most from the performance of the equity portfolio was our avoidance of a number of financial services companies, including American International Group, Inc. (AIG), Freddie Mac and American Express Co., which performed well during the period. We believe that the Federal Reserve Board (the Fed) is prepared to increase short-term interest rates several more times, which may not bode well for the profits of these financial services companies. In addition, we believe increased regulatory scrutiny will heighten pressure on pricing of AIG's products and impact the long-term investment return available to AIG shareholders. What changes were made to the portfolio during the period? A mathematical formula is used to determine the allocation between the Fund's equity and fixed income components. During the six-month period, the Fund's equity component ranged from 59.1% of net assets to 66.2%, and the fixed income allocation ranged from 33.8% of net assets to 40.9%. The Fund's fixed income component was invested in U.S. Treasury zero-coupon bonds set to mature close to the expiration of the Fund, which is seven years from its commencement of operations (November 13, 2009). MERRILL LYNCH FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2006 In the equity portfolio, we sold our position in Microsoft Corporation and replaced it with investments in information technology companies in India, where valuations appear reasonable and growth in revenue, earnings and rates of return is much stronger than we are seeing among U.S. information technology companies. Also during the period, we opted not to invest in Dell, Inc. and Intel Corp., two of the leading technology companies in the United States. This proved to be a positive in terms of relative performance. Overall, we continue to significantly underweight the information technology sector relative to our equity benchmarks. We believe that companies in China, South Korea and Taiwan are gaining the upper-hand in supplying both computing and communication equipment systems to the world's major customers, both private and public. In the information technology software and services sector, we look to the investment opportunities among the leading companies in India. The Indian companies added to the portfolio during the period were Cognizant Technology Solutions Corp., Satyam Computer Services Ltd., Tata Consultancy Services Ltd. and Infosys Technologies Ltd. The Fund's equity portfolio also is relatively underinvested in companies in the consumer discretionary sector. In our view, the combination of higher interest rates and more limited availability of residential real estate financing is reducing the liquidity available to families to purchase or update new or existing homes. Similarly, the higher cost of energy and public services is reducing the discretionary income of households, further supporting our underweight position in the consumer discretionary sector. Our focus during the period continued to be on the energy sector, where private companies and governments are increasing their spending in efforts to find new reserves of oil and other energy resources. We were also attracted to industrial companies providing new electric power generating equipment and commercial aviation craft and other industrial and commercial equipment to the rapidly growing economies in Asia, where China leads the capital investment boom. How would you characterize the Fund's position at the close of the period? In seeking to meet its objective of principal protection and potential for capital growth, the allocation between the Fund's fixed income and equity components will continue to vary as market conditions change. As of February 28, 2006, the Fund was invested 65.6% in equities and 33.8% in fixed income securities as a percent of net assets. This compared to an allocation of 59.8% equities and 37.7% fixed income six months ago. The equity portfolio ended the period overweight in the energy, industrials and materials sectors, reflecting our view that global economic growth is relatively strong. However, the strength in demand growth for both consumer and industrial capital goods is lodged in the Asia-Pacific region, particularly in China, where the nation's economic growth plans are resulting in economic growth rates near 10%. The demand for products, materials, energy and services over the next five years could be unprecedented in modern times. Secondarily, the economic growth and development plans of the government of India are a meaningful contributor to the demand for sophisticated industrial and commercial products and systems, as many millions of people are drawn into the middle-class sector of the society. In the United States, we anticipate that demand for the services of HMOs (health maintenance organizations) will remain strong over the intermediate- term as these private organizations become major suppliers and administrators of what traditionally have been public sector healthcare services. The relative magnitude and growth in demand for healthcare services has overwhelmed the federal and state governments, and the HMOs are being enlisted as the providers of a rational delivery system for services. Also, we are focused on biotechnology companies in the pharmaceutical area, where the products are relatively moderate in price and efficacious at prolonging and improving the quality of life. Against this backdrop, the health care sector is an important part of our research efforts and our investments in this sector are highly focused. Lawrence R. Fuller Vice President and Equity Portfolio Manager March 15, 2006 After a distinguished 38-year career, Portfolio Manager Larry Fuller announced his retirement from the investment management business, effective March 31, 2006. Mr. Fuller began his career in 1968. He joined Merrill Lynch Investment Managers (MLIM) in October 1992 and was Equity Portfolio Manager of Merrill Lynch Fundamental Growth Principal Protected Fund since its inception in 2002. He also managed several other related portfolios. Mr. Fuller has been a successful portfolio manager highly regarded for his experience, insights and warmth. Thomas E. Burke, the Fund's associate portfolio manager who has worked closely with Mr. Fuller for 13 years, has become Portfolio Manager of the Fund, effective the same date. Mr. Fuller's colleagues at MLIM join the Fund's Board of Trustees in wishing Mr. Fuller well in his retirement. MERRILL LYNCH FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2006 Performance Data About Fund Performance Investors are able to purchase shares of the Fund through multiple pricing alternatives: * Class A Shares incur a maximum initial sales charge (front-end load) of 5.25% and an account maintenance fee of 0.25% per year (but no distribution fee). * Class B Shares are subject to a maximum contingent deferred sales charge of 4% declining to 0% after six years. In addition, Class B Shares are subject to a distribution fee of 0.75% per year and an account maintenance fee of 0.25% per year. These shares automatically convert to Class A Shares after approximately eight years. (There is no initial sales charge for automatic share conversions.) All returns for periods greater than eight years reflect this conversion. * Class C Shares are subject to a distribution fee of 0.75% per year and an account maintenance fee of 0.25% per year. In addition, Class C Shares are subject to a 1% contingent deferred sales charge if redeemed within one year of purchase. * Effective December 28, 2005, Class I Shares are no longer subject to any front-end sales charge. Class I Shares bear no ongoing distribution or account maintenance fees and are available only to eligible investors. Had the sales charge been included, the Fund's Class I Shares' performance would have been lower. None of the past results shown should be considered a representation of future performance. Current performance may be lower or higher than the performance data quoted. Refer to www.mlim.ml.com to obtain performance data current to the most recent month-end. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the following tables assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the ex-dividend date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of account maintenance, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders.

The following example (which is based on a hypothetical investment of $1,000 invested on September 1, 2005 and held through February 28, 2006) is intended to assist shareholders both in calculating expenses based on an investment in the Fund and in comparing these expenses with similar costs of investing in other mutual funds. The first table below provides information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period." The second table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in this Fund and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds' shareholder reports. The expenses shown in the table are intended to highlight shareholders' ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees or exchange fees. Therefore, the second table is useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher. Expenses Paid Beginning Ending During the Period* Account Value Account Value September 1, 2005 September 1, February 28, to February 28, 2005 2006 2006 Actual Class A $1,000 $1,026.30 $10.05 Class B $1,000 $1,022.10 $13.84 Class C $1,000 $1,021.70 $13.89 Class I $1,000 $1,027.80 $ 8.80 Hypothetical (5% annual return before expenses)** Class A $1,000 $1,014.88 $ 9.99 Class B $1,000 $1,011.11 $13.76 Class C $1,000 $1,011.06 $13.81 Class I $1,000 $1,016.12 $ 8.75 * For each class of the Fund, expenses are equal to the annualized expense ratio for the class (2.00% for Class A, 2.76% for Class B, 2.77% for Class C and 1.75% for Class I), multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period shown). ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent fiscal half year divided by 365.

Significant Accounting Policies: Merrill Lynch Fundamental Growth Principal Protected Fund (the "Fund") is part of Merrill Lynch Principal Protected Trust (the "Trust"). The Fund is a separate diversified series of the Trust, which is registered as an open-end management investment company under the Investment Company Act of 1940, as amended. The Fund's financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to present a fair statement of the results for the interim period. All such adjustments are of a normal, recurring nature. The Fund offers multiple classes of shares. Shares of the Fund were offered during the initial offering period but will not be offered during the Guarantee Period from November 13, 2002 through November 13, 2009 (the "Guarantee Maturity Date"), except in connection with reinvestment of dividends and distributions. The Fund will be offered on a continuous basis after the Guarantee Maturity Date without the principal protection feature. Effective December 28, 2005, Class I Shares are no longer subject to any front- end sales charge. Class A Shares are sold with a front-end sales charge. Shares of Class B and Class C may be subject to a contingent deferred sales charge. Class I Shares are sold only to certain eligible investors. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Class A, Class B and Class C Shares bear certain expenses related to the account maintenance of such shares, and Class B and Class C Shares also bear certain expenses related to the distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its account maintenance and distribution expenditures (except that Class B shareholders may vote on certain changes to the Class A distribution plan). Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments--Equity securities that are held by the Fund that are traded on stock exchanges or the Nasdaq National Market are valued at the last sale price or official close price on the exchange, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price for long positions, and at the last available asked price for short positions. In cases where equity securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Trustees of the Fund. Long positions traded in the over-the-counter ("OTC") market, Nasdaq Small Cap or Bulletin Board are valued at the last available bid price or yield equivalent obtained from one or more dealers or pricing services approved by the Board of Trustees of the Fund. Short positions traded in the OTC market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. Options written are valued at the last sale price in the case of exchange- traded options or, in the case of options traded in the OTC market, the last asked price. Options purchased are valued at their last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last bid price. Swap agreements are valued based upon quoted fair valuations received daily by the Fund from a pricing service or counterparty. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless the Investment Adviser believes that this method no longer produces fair valuations. Repurchase agreements are valued at cost plus accrued interest. The Fund employs pricing services to provide certain securities prices for the Fund. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Trustees of the Fund, including valuations furnished by the pricing services retained by the Fund, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Fund under the general supervision of the Fund's Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Fund. MERRILL LYNCH FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2006 Notes to Financial Statements (continued) Generally, trading in foreign securities, as well as U.S. government securities, money market instruments and certain fixed income securities, is substantially completed each day at various times prior to the close of business on the New York Stock Exchange ("NYSE"). The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Foreign currency exchange rates also are generally determined prior to the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates may occur between the times at which they are determined and the close of business on the NYSE that may not be reflected in the computation of the Fund's net asset value. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such securities, those securities may be valued at their fair value as determined in good faith by the Fund's Board of Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the Fund's Board of Trustees. (b) Derivative financial instruments--The Fund may engage in various portfolio strategies both to increase the return of the Fund and to hedge, or protect, its exposure to interest rate movements and movements in the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. * Financial futures contracts--The Fund may purchase or sell financial futures contracts and options on such futures contracts. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. 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 value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund records a realized 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. * Options--The Fund may write and purchase call and put options. When the Fund writes an option, an amount equal to the premium received by the Fund is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked-to-market to reflect the current value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Fund enters into a closing transaction), the Fund realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. (c) Foreign currency transactions--Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets or liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. The Fund invests in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. (d) Income taxes--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. Therefore, no federal income tax provision is required. Under the applicable foreign tax law, a withholding tax may be imposed on interest, dividends and capital gains at various rates. MERRILL LYNCH FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2006 Notes to Financial Statements (continued) (e) Security transactions and investment income--Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Dividends from foreign securities where the ex-dividend date may have passed are subsequently recorded when the Fund has determined the ex-dividend date. Interest income is recognized on the accrual basis. The Fund amortizes all premiums and discounts on debt securities. (f) Dividends and distributions--Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. (g) Securities lending--The Fund may lend securities to financial institutions that provide cash or securities issued or guaranteed by the U.S. government as collateral, which will be maintained at all times in an amount equal to at least 100% of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. Where the Fund receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Fund typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Fund receives cash collateral, it may invest such collateral and retain the amount earned on such investment, net of any amount rebated to the borrower. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within five business days. The Fund may pay reasonable finder's, lending agent, administrative and custodial fees in connection with its loans. In the event that the borrower defaults on its obligation to return borrowed securities because of insolvency or for any other reason, the Fund could experience delays and costs in gaining access to the collateral. The Fund also could suffer a loss where the value of the collateral falls below the market value of the borrowed securities, in the event of borrower default or in the event of losses on investments made with cash collateral. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund has entered into an Investment Advisory Agreement with Merrill Lynch Investment Managers, L.P. ("MLIM"). The general partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. The Fund has also entered into a Distribution Agreement and Distribution Plan with FAM Distributors, Inc. ("FAMD" or the "Distributor"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc. MLIM is responsible for the management of the Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund. For such services, the Fund pays a monthly fee at the annual rate of .65% of the Fund's average daily net assets. MLIM has entered into a contractual arrangement with the Fund under which the expenses incurred by each class of shares of the Fund (excluding distribution and/or account maintenance fees) will not exceed 1.99%. This arrangement has a one-year term and is automatically renewable. Pursuant to the Distribution Plan adopted by the Fund in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor ongoing account maintenance and distribution fees. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the shares as follows: Account Maintenance Distribution Fee Fee Class A .25% -- Class B .25% .75% Class C .25% .75% Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), an affiliate of MLIM, also provides account maintenance and distribution services to the Fund. The ongoing account maintenance fee compensates the Distributor and MLPF&S for providing account maintenance services to Class A, Class B and Class C shareholders. The ongoing distribution fee compensates the Distributor and MLPF&S for providing shareholder and distribution-related services to Class B and Class C shareholders. For the six months ended February 28, 2006, MLPF&S received contingent deferred sales charges of $194,047 relating to transactions in Class B Shares. MERRILL LYNCH FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2006 Notes to Financial Statements (continued) The Trust, on behalf of the Fund, has entered into a Financial Warranty Agreement with Main Place Funding, LLC (the "Warranty Provider"). The Financial Warranty Agreement is intended to make sure that on the Guarantee Maturity Date, each shareholder of the Fund will be entitled to redeem his or her shares for an amount no less than the initial value of that shareholder's account (less expenses and sales charges not covered by the Financial Warranty Agreement), provided that all dividends and distributions received from the Fund have been reinvested and no shares have been redeemed (the "Guaranteed Amount"). The Fund will pay to the Warranty Provider, under the Financial Warranty Agreement, an annual fee equal to .80% of the Fund's average daily net assets during the Guarantee Period. If the value of the Fund's assets on the Guarantee Maturity Date is insufficient to result in the value of each shareholder's account being at least equal to the shareholder's Guaranteed Amount, the Warranty Provider will pay the Fund an amount sufficient to make sure that each shareholder's account can be redeemed for an amount equal to his or her Guaranteed Amount. The Fund has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to MLPF&S or its affiliates. Pursuant to that order, the Fund also has retained Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM, as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. MLIM, LLC may, on behalf of the Fund, invest cash collateral received by the Fund for such loans, among other things, in a private investment company managed by MLIM, LLC or in registered money market funds advised by MLIM or its affiliates. For the six months ended February 28, 2006, MLIM, LLC received $4,583 in securities lending agent fees. In addition, MLPF&S received $4,666 in commissions on the execution of portfolio security transactions for the Fund for the six months ended February 28, 2006. For the six months ended February 28, 2006, the Fund reimbursed MLIM $1,520 for certain accounting services. Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is the Fund's transfer agent. Certain officers and/or trustees of the Fund are officers and/or directors of MLIM, FDS, PSI, FAMD, ML & Co., and/or MLIM, LLC. In February 2006, ML & Co. and BlackRock, Inc. entered into an agreement to merge ML & Co.'s investment management business, including MLIM, with the investment management business of BlackRock, Inc. The transaction is expected to close in the third quarter of 2006. 3.

The Fund may borrow up to the maximum amount allowable under the Fund's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. The Fund pays a commitment fee of .07% per annum based on the Fund's pro rata share of the unused portion of the credit agreement.

MERRILL LYNCH FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2006 Disclosure of Investment Advisory Agreement Activities and Composition of the Board of Trustees All but one member of the Board of Trustees is an independent trustee whose only affiliation with Fund Asset Management, L.P. (the "Investment Adviser") or other Merrill Lynch affiliates is as a trustee of the Trust and certain other funds advised by the Investment Adviser or its affiliates. The Chair of the Board is an independent trustee. New trustee nominees are chosen by a Nominating Committee comprised entirely of independent trustees. All independent trustees also are members of the Board's Audit Committee and the independent trustees meet in executive session at each in-person Board meeting. The Board and the Audit Committee meet in person for at least two days each quarter and conduct other in-person and telephone meetings throughout the year, some of which are formal Board meetings, and some of which are informational meetings. Independent counsel to the independent trustees attends all in-person Board and Audit Committee meetings and other meetings at the independent trustees' request. Investment Advisory Agreement--Matters Considered by the Board Every year, the Board considers approval of the Trust's investment advisory agreement (the "Investment Advisory Agreement"). The Board assesses the nature, scope and quality of the services provided to the Trust by the personnel of the Investment Adviser and their affiliates, including administrative services, shareholder services, oversight of fund accounting, marketing services and assistance in meeting legal and regulatory requirements. The Board also receives and assesses information regarding the services provided to the Trust by certain unaffiliated service providers. At various times throughout the year, the Board also considers a range of information in connection with its oversight of the services provided by the Investment Adviser and its affiliates. Among the matters considered are: (a) fees (in addition to management fees) paid to the Investment Adviser and its affiliates by the Trust, such as transfer agency fees and fees for marketing and distribution; (b) Trust operating expenses paid to third parties; (c) the resources devoted to and compliance reports relating to the Trust's investment objective, policies and restrictions, and its compliance with its Code of Ethics and the Investment Adviser's compliance policies and procedures; and (d) the nature, cost and character of non-investment management services provided by the Investment Adviser and its affiliates. The Board believes that the Investment Adviser is one of the most experienced global asset management firms and considers the overall services provided by the Investment Adviser to be of high quality. The Board also believes that the Investment Adviser is financially sound and well managed and notes that the Investment Adviser is affiliated with one of America's largest financial firms. The Board works closely with the Investment Adviser in overseeing the Investment Adviser's efforts to achieve good performance. As part of this effort, the Board discusses portfolio manager effectiveness and, when performance is not satisfactory, discusses with the Investment Adviser taking steps such as changing investment personnel. Annual Consideration of Approval by the Board of Trustees In the period prior to the Board meeting to consider renewal of the Investment Advisory Agreement, the Board requests and receives materials specifically relating to the Trust's Investment Advisory Agreement. These materials include (a) information compiled by Lipper Inc. ("Lipper") on the fees and expenses and the investment performance of the Trust as compared to a comparable group of funds as classified by Lipper; (b) sales and redemption data for the Trust; (c) a discussion by the Trust's portfolio management team of investment strategies used by the Trust during its most recent fiscal year; (d) information on the profitability to the Investment Adviser and its affiliates of the Investment Advisory Agreement and other relationships with the Trust; and (e) information provided by the Investment Adviser concerning investment advisory fees charged to other clients, such as other mutual funds and offshore funds under similar investment mandates. The Board also considers other matters it deems important to the approval process such as payments made to the Investment Adviser or its affiliates relating to the distribution of Trust shares, services related to the valuation and pricing of Trust portfolio holdings, the Trust's portfolio turnover statistics, and direct and indirect benefits to the Investment Adviser and its affiliates from their relationship with the Trust. The Board did not identify any particular information as controlling, and each member of the Board attributed different weights to the various items considered. MERRILL LYNCH FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2006 Disclosure of Investment Advisory Agreement (continued) Certain Specific Renewal Data In connection with the most recent renewal of the Trust's Investment Advisory Agreement in February, 2006, the independent trustees' and Board's review included the following: Services Provided by the Investment Adviser--The Board reviewed the nature, extent and quality of services provided by the Investment Adviser, including the investment advisory services and the resulting performance of the Trust. The Board focused primarily on the Investment Adviser's investment advisory services and the Trust's investment performance. The Board compared Trust performance - both including and excluding the effects of the Trust's fees and expenses - to the performance of a comparable group of mutual funds, and the performance of a relevant index or combination of indexes. While the Board reviews performance data at least quarterly, consistent with the Investment Adviser's investment goals, the Board attaches more importance to performance over relatively long periods of time, typically three to five years, or a shorter period in the case of a fund that has been in existence less than five years. For the periods ended November 30, 2005, the Fund's performance after fees and expenses ranked in the first quintile for the one-year period and in the second quintile for the three-year period. The Board concluded that the nature and quality of the services supported the continuation of the Investment Advisory Agreement. The Investment Adviser's Personnel and Investment Process--The Board reviews at least annually the Trust's investment objectives and strategies. The Board discusses with senior management of the Investment Adviser responsible for investment operations and the senior management of the Investment Adviser's equity investing group the strategies being used to achieve the stated objectives. Among other things, the Board considers the size, education and experience of the Investment Adviser's investment staff, its use of technology, and the Investment Adviser's approach to training and retaining portfolio managers and other research, advisory and management personnel. The Board also reviews the Investment Adviser's compensation policies and practices with respect to the Trust's portfolio managers. The Board also considered the experience of the Fund's portfolio managers and noted that Lawrence Fuller is the Fund's portfolio manager and is primarily responsible for the day-to-day management of the Fund's portfolio and the selection of its investments. The Board also noted that Thomas Burke is the associate portfolio manager of the Fund. Mr. Fuller has more than 38 years' experience in portfolio management and Mr. Burke has more than 25 years' experience in portfolio management. Moreover, the Investment Adviser and its investment staff have extensive experience in analyzing and managing the types of investments used by the Fund. The Board concluded that the Fund benefits from that expertise. Management Fees and Other Expenses--The Board reviews the Trust's contractual management fee rate and actual management fee rate as a percentage of total assets at common asset levels - the actual rate includes advisory and administrative service fees and the effects of any fee waivers - compared to the other funds considered comparable by Lipper. It also compares the Trust's total expenses to those of other comparable funds. The Board was advised by the Investment Adviser that there were no comparable clients or accounts with similar investment mandates. The Board noted that the Fund's contractual and actual management fee rates were lower than the median of management fees charged by comparable funds, as determined by Lipper, while the Fund's total expenses were above the median expenses charged by such comparable funds. The Board noted that the higher than median expenses primarily related to the expenses associated with a warranty agreement between the Fund and an unaffiliated third party. The Board also noted that if all the Fund's assets are irreversibly allocated to the Fund's Protection Component under the terms of the Warranty Agreement, the management fee will be reduced to 0.25%. The Board concluded that the Trust's management fee rate and overall expense ratio are reasonable when compared to those of other comparable funds. Profitability--The Board considers the cost of the services provided to the Trust by the Investment Adviser, and the Investment Adviser's and its affiliates' profits relating to the management and distribution of the Trust and the MLIM/FAM-advised funds. As part of its analysis, the Board reviewed the Investment Adviser's methodology in allocating its costs to the management of the Trust and concluded that there was a reasonable basis for the allocation. The Board also considered federal court decisions discussing an investment adviser's profitability and profitability levels considered to be reasonable in those decisions. The Board concluded that the profits of the Investment Adviser and its affiliates are acceptable in relation to the nature and quality of services provided and given the level of fees and expenses overall. MERRILL LYNCH FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2006 Disclosure of Investment Advisory Agreement (concluded) Economies of Scale--The Board considered the extent to which economies of scale might be realized as the assets of the Trust increase and whether there should be changes in the management fee rate or structure in order to enable the Trust to participate in these economies of scale. While there was no evidence to date that the Trust's assets have reached a level where such economies are effectively available, the Board will continue to seek information relating to economies of scale. The Board determined that the management fee structure was reasonable and that no changes were currently necessary. Conclusion After the independent trustees deliberated in executive session, the entire Board, including all of the independent trustees, approved the renewal of the existing Investment Advisory Agreement, concluding that the advisory fee was reasonable in relation to the services provided and that a contract renewal was in the best interests of the shareholders.
