MERRILL LYNCH HEALTHCARE FUND, INC., APRIL 30, 2005 A Letter From the President Dear Shareholder Financial markets faced a number of crosscurrents over the past several months, but most major benchmarks managed to post positive returns for the annual and semi-annual reporting periods ended April 30, 2005: Total Returns as of April 30, 2005 6-month 12-month U.S. equities (Standard & Poor's 500 Index) +3.28% + 6.34% Small-cap U.S. equities (Russell 2000 Index) -0.15% + 4.71% International equities (MSCI Europe Australasia Far East Index) +8.71% +14.95% Fixed income (Lehman Brothers Aggregate Bond Index) +0.98% + 5.26% Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) +1.93% + 6.81% High yield bonds (Credit Suisse First Boston High Yield Index) +0.65% + 6.92% After expanding at an annualized rate of 4.4% in 2004, U.S. gross domestic product growth for the first quarter of 2005 came in at an estimated 3.1% (although that figure was later revised upward to 3.5%). Nevertheless, the Federal Reserve Board continued increasing interest rates at a measured pace to combat emergent inflation. The most recent hike came on May 3, and brought the federal funds rate to 3%. Recently, signs of inflation have taken the form of rising business costs and increasing consumer prices, particularly in the areas of gasoline, healthcare, housing and education. U.S. equities ended 2004 in a strong rally, but stumbled into negative territory in 2005. The market weakness was largely fueled by the potential for slowing economic and corporate earnings growth, renewed energy price concerns and a lack of investor conviction. On the positive side, certain sectors of the market have been performing well (particularly energy) and corporate transactions, such as mergers and acquisitions, stock buy-backs and dividend payouts, have all increased. International equities, especially in Asia, have benefited from higher economic growth rates. In the bond market, we witnessed a yield curve flattening trend over the past several months as short-term yields increased and longer-term interest rates remained more stable or fell. At the end of April 2005, the two-year Treasury note yielded 3.66% and the 10-year Treasury note yielded 4.21%, a difference of 55 basis points (.55%). This compared to a spread of 149 basis points six months earlier and 222 basis points 12 months ago. Looking ahead, the environment is likely to be a challenging one for investors. With this in mind, we encourage you to meet with your financial advisor to review your goals and asset allocation and to rebalance your portfolio, as necessary, to ensure it remains aligned with your objectives and risk tolerance. As always, we thank you for trusting Merrill Lynch Investment Managers with your investment assets, and we look forward to serving you in the months and years ahead. Sincerely, (Robert C. Doll, Jr.) Robert C. Doll, Jr. President and Director MERRILL LYNCH HEALTHCARE FUND, INC., APRIL 30, 2005 A Discussion With Your Fund's Portfolio Manager In an effort to generate gains while containing risk, we remained focused on our long-term strategy of balancing the upside potential of growth-oriented subsectors with the downside support offered by the more defensive areas of healthcare. How did the Fund perform during the fiscal year in light of the existing market conditions? For the year ended April 30, 2005, Merrill Lynch Healthcare Fund, Inc.'s Class A, Class B, Class C, Class I and Class R Shares had total returns of +.74%, -.09%, -.09%, +.99% and +.54%, 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 Standard and Poor's 500 Index, which represents the broader stock market rather than healthcare stocks alone, returned +6.34%, while the Fund's composite benchmark, which comprises four Morgan Stanley Capital International (MSCI) industries,* returned +7.93%. Fund returns outpaced the average of the Lipper Health/Biotechnology Funds category, which measures the performance of mutual funds that focus their investment on companies engaged in healthcare and biotechnology. The Lipper Health/Biotechnology Funds category provided an average return of -.79% for the year ended April 30, 2005. The past 12 months were marked by a sustainable economic recovery in the United States. Gross domestic product (GDP) grew at an annualized rate of 4.4% for 2004, well ahead of the 3% annual growth rate registered in 2003. As the economic expansion progressed, short-term interest rates rose from their historically low levels as the Federal Reserve Board embarked on a program of "measured" monetary tightening. At the same time, energy prices soared as extraordinary growth in the Chinese economy boosted overall demand. These increases started in May 2004 and continued for the remainder of the period. As a result, energy and other commodity share prices rose to record levels, as did share prices in these sectors. * The Fund's composite benchmark comprises the following four MSCI industries: health care equipment and supplies (15%), health care providers and services (25%), biotechnology (25%) and pharmaceuticals (35%). Overall, equity market trading was confined to a fairly narrow range for much of the fiscal year. A turning point came in November, when the Bush election victory triggered a robust rally that lasted until March 2005. At that point, it appeared that the cumulative impact of 12 months of rising interest rates and energy costs had begun to pressure the economy and the equity market. An advanced GDP figure for the first quarter of 2005 came in lower than expected at 3.1%, although that figure was later revised upward to 3.5%. During this 12-month period, health care was one of the poorest performing industry sectors, which accounts for the Fund's underperformance of the broad- market S&P 500 Index. Pharmaceuticals continued to suffer from an anemic new product flow, as well as intense generic drug price pressure and attempts to invalidate patents. While valuations on pharmaceutical stocks are reasonable, both historically and relatively, the upside, in our judgment, appears limited by negative public perception of the industry. This unfavorable attitude has spilled over to the political and regulatory spheres. Several recent, well-publicized drug marketing withdrawals and possible Congressional action to ease imports from Canada illustrate the climate. In the United States, there is now an adversarial climate between a highly safety-conscious Food and Drug Administration (FDA) and the drug industry. The public antipathy is largely based on the high cost of medications, especially when compared to lower prices on the same drugs sold overseas. Biotechnology stocks, which are always more risky, have been impacted by some of the same pressures, although generic competition is limited. Only managed health care (HMO) stocks posted gains during the year as the Republican victory positioned this subgroup as the vehicle to administer the government's greatly expanded Medicare program. We believe the Fund performed satisfactorily in this climate. The stronger performance of the composite benchmark largely reflects the absence in that index of small biotechnology holdings, which were severely impacted by a lack of "news flow" during May through October. News flow arises from scientific meetings, which were not scheduled during the summer hiatus. Since these biotechnology companies did not have earnings or dividends to support share prices during a period of market weakness, the absence of news developments was particularly meaningful. Also damaging to performance was the Fund's position in biotechnology company Biogen Idec Inc., which was severely impacted by the FDA's suspension of sales of the company's multiple sclerosis treatment drug. We liquidated our position in Biogen. MERRILL LYNCH HEALTHCARE FUND, INC., APRIL 30, 2005 What changes were made to the portfolio during the year? The Fund gradually adapted a more defensive stance during the 12-month period. The total number of holdings was reduced from 80 to 58. We continued to pursue a "barbell" strategy, seeking to balance risk and reward in the portfolio. We emphasized HMOs and pharmaceuticals to provide downside support in a fragile equity market. Non-U.S.-based pharmaceutical companies were an investment focus. For upside potential, we continued to look to biotechnology companies, especially those with important new discoveries in cancer treatment. We did give greater weight to more mature biotechnology companies, such as Genentech, Inc. and Amgen, Inc., with profitable products on the market. We substantially reduced small cap biotechnology holdings. We took profits on the Fund's hospital stocks, which provided a source of funds for our new purchases. The Fund's exposure to pharmaceutical stocks was largely unchanged. We continued to avoid generic drug companies, with the exception of two Indian companies - Sun Pharmaceuticals Industries Ltd. and Cadila Healthcare Ltd., both of which remained attractive given their competitive cost advantages. Over the year, the Fund's U.S. holdings were increased from 76% of net assets to 82% by period-end. Significant positions outside the United States included Japanese drug company Takeda Pharmaceutical Co., Ltd.; the two major Swiss-based pharmaceutical companies, Novartis AG and Roche Holding AG; and the largest French drug company, Sanofi-Aventis. How would you characterize the Fund's position at the close of the period? As mentioned earlier, we shifted the portfolio to a more defensive posture in the past year, although its subsector structure was little changed. In addition to decreasing the total number of holdings in the portfolio, we increased the Fund's position in large cap holdings from 49% of net assets to 71% by period-end. This included greater exposure to dividend-paying pharmaceutical companies. Notwithstanding the hills and valleys of the economic cycle, we believe healthcare is a core long-term investment area driven by an aging population, continued scientific discovery, and economic advances in China, India and other less developed parts of the world. Overall, we continue to pursue a growth-oriented investment strategy. At the same time, we are sensitive to stock valuations and remain diversified across the breadth of health care subsectors.

All Class B Shares purchased prior to June 1, 2001 will maintain the four-year schedule. 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. * Class I Shares incur a maximum initial sales charge (front-end load) of 5.25% and bear no ongoing distribution or account maintenance fees. Class I Shares are available only to eligible investors. * Class R Shares do not incur a maximum sales charge (front-end load) or deferred sales charge. These shares are subject to a distribution fee of 0.25% per year and an account maintenance fee of 0.25% per year. Class R Shares are available only to certain retirement plans. Prior to inception, Class R Share performance results are those of Class I Shares (which have no distribution or account maintenance fees) restated for Class R Share fees. 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 November 1, 2004 and held through April 30, 2005) 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 November 1, 2004 to November 1, April 30, April 30, 2004 2005 2005 Actual Class A $1,000 $1,079.50 $ 8.24 Class B $1,000 $1,074.10 $12.20 Class C $1,000 $1,076.50 $12.27 Class I $1,000 $1,081.70 $ 6.85 Class R $1,000 $1,077.50 $ 9.53 Hypothetical (5% annual return before expenses)** Class A $1,000 $1,016.97 $ 8.00 Class B $1,000 $1,013.13 $11.84 Class C $1,000 $1,013.08 $11.89 Class I $1,000 $1,018.32 $ 6.64 Class R $1,000 $1,015.73 $ 9.25 * For each class of the Fund, expenses are equal to the annualized expense ratio for the class (1.59% for Class A, 2.36% for Class B, 2.37% for Class C, 1.32% for Class I and 1.84% for Class R), multiplied by the average account value over the period, multiplied by 182/365. ** 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.

See Notes to Financial Statements. MERRILL LYNCH HEALTHCARE FUND, INC., APRIL 30, 2005 Notes to Financial Statements 1. Significant Accounting Policies: Merrill Lynch Healthcare Fund, Inc. (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a non-diversified, open-end management investment company. 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. The Fund offers multiple classes of shares. Shares of Class A and Class I 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 R Shares are sold only to certain retirement plans. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Class A, Class B, Class C and Class R Shares bear certain expenses related to the account maintenance of such shares, and Class B, Class C and Class R 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 on investments and foreign currency transactions 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 securities--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 Directors 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 Directors 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 daily based upon quotations from market makers. 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 Directors 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 Directors. Such valuations and procedures will be reviewed periodically by the Board of Directors of the Fund. Generally, trading in foreign securities, as well as U.S. government securities and money market instruments, 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 Directors or by the Investment Adviser using a pricing service and/or procedures approved by the Fund's Board of Directors. MERRILL LYNCH HEALTHCARE FUND, INC., APRIL 30, 2005 Notes to Financial Statements (continued) (b) 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. (c) Derivative financial instruments--The Fund may engage in various portfolio investment 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 contacts 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. * Foreign currency options and futures--The Fund may also purchase or sell listed or over-the-counter foreign currency options, foreign currency futures and related options on foreign currency futures as a short or long hedge against possible variations in foreign exchange rates. Such transactions may be effected with respect to hedges on non-U.S. dollar denominated securities owned by the Fund, sold by the Fund but not yet delivered, or committed or anticipated to be purchased by the Fund. * Forward foreign exchange contracts--The Fund may enter into forward foreign exchange contracts as a hedge against either specific transactions or portfolio positions. The contract is marked-to-market daily and the change in market value is recorded by the Fund as an unrealized gain or loss. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. * Options--The Fund may purchase and write 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 market 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. (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. (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. (f) Prepaid registration fees--Prepaid registration fees are charged to expense as the related shares are issued. MERRILL LYNCH HEALTHCARE FUND, INC., APRIL 30, 2005 Notes to Financial Statements (continued) (g) Dividends and distributions--Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. (h) 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, the Fund typically receives the income on both the loaned securities and the collateral and, as a result, the Fund's yield may increase. 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. The Fund may receive a flat fee for its loans. 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. (i) Custodian bank--The Fund recorded an amount payable to the custodian bank reflecting an overnight overdraft, which resulted from a failed trade that settled the next day. (j) Reclassifications--U.S. generally accepted accounting principles require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, during the current year, $8,019,533 has been reclassified between paid-in capital in excess of par and accumulated net investment loss and $399,975 has been reclassified between accumulated net investment loss and undistributed net realized capital gains as a result of permanent differences attributable to net operating losses, foreign currency transactions and non-deductible expenses. These reclassifications have no effect on net assets or net asset values per share. 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, or arranges for affiliates to provide, the administrative services necessary for the operation of the Fund. As compensation for its services to the Fund, MLIM receives monthly compensation at the annual rate of 1.0% of the average daily net assets of the Fund. MLIM has entered into a Sub-Advisory Agreement with Merrill Lynch Asset Management U.K. Limited ("MLAM U.K."), an affiliate of MLIM, pursuant to which MLAM U.K. provides investment advisory services to MLIM with respect to the Fund. There is no increase in the aggregate fees paid by the Fund for these services. 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% Class R .25% .25% 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, Class C and Class R shareholders. The ongoing distribution fee compensates the Distributor and MLPF&S for providing shareholder and distribution-related services to Class B, Class C and Class R shareholders. MERRILL LYNCH HEALTHCARE FUND, INC., APRIL 30, 2005 Notes to Financial Statements (continued) For the year ended April 30, 2005, FAMD earned underwriting discounts and direct commissions and MLPF&S earned dealer concessions on sales of the Fund's Class A and Class I Shares as follows: FAMD MLPF&S Class A $ 3,056 $ 38,168 Class I $ 70 $ 913 For the year ended April 30, 2005, MLPF&S received contingent deferred sales charges of $193,924 and $7,550 relating to transactions in Class B and Class C Shares, respectively. Furthermore, MLPF&S received contingent deferred sales charges of $192 relating to transactions subject to front-end sales charge waivers in Class A Shares. 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. As of April 30, 2005, the Fund lent securities with a value of $5,121,948 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 year ended April 30, 2005, MLIM, LLC received $84,942 in securities lending agent fees. In addition, MLPF&S received $818,400 in commissions on the execution of portfolio security transactions for the Fund for the year ended April 30, 2005. Financial Data Services, Inc.

Short-Term Borrowings: The Fund, along with certain other funds managed by MLIM and its affiliates, is a party to a $500,000,000 credit agreement with a group of lenders. The Fund may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. 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. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each Fund's election, the federal funds rate plus .50% or a base rate as defined in the credit agreement. The Fund did not borrow under the credit agreement during the year ended April 30, 2005. On November 26, 2004, the credit agreement was renewed for one year under substantially the same terms. 6. Commitments: At April 30, 2005, the Fund had outstanding foreign exchange contracts, under which it agreed to purchase a foreign currency with an approximate value of $1,173,000. 7.

MERRILL LYNCH HEALTHCARE FUND, INC., APRIL 30, 2005 Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors of Merrill Lynch Healthcare Fund, Inc.: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Merrill Lynch Healthcare Fund, Inc. as of April 30, 2005, and the related statement of operations for the year then ended, the statements of 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 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 April 30, 2005, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 Merrill Lynch Healthcare Fund, Inc. as of April 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 its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles. Deloitte & Touche LLP Princeton, New Jersey June 17, 2005 Important Tax Information (unaudited) Merrill Lynch Healthcare Fund, Inc. paid long-term capital gain distributions of $.189870 and $.181324 per share to shareholders of record on July 21, 2004 and December 15, 2004, respectively.

MERRILL LYNCH HEALTHCARE FUND, INC., APRIL 30, 2005 Disclosure of Investment Advisory Agreement Activities of and Composition of the Board of Directors All but one member of the Board of Directors is an independent director whose only affiliation with Merrill Lynch Investment Managers, L.P. (the "Investment Adviser") or other Merrill Lynch affiliates is as a director of the Fund and certain other funds advised by the Investment Adviser or its affiliates. The Chairman of the Board is also an independent director. New director nominees are chosen as nominees by a Nominating Committee comprised of independent directors. All independent directors also are members of the Board's Audit Committee and the independent directors 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. The independent counsel to the independent directors attends all in person Board and Audit Committee meetings and other meetings at the independent directors' request. Investment Advisory Agreement--Matters Considered by the Board Every year, the Board considers approval of the Fund's investment advisory agreement (the "Investment Advisory Agreement"). The Board also annually reviews and considers approval of the sub-advisory agreement on behalf of the Fund between the Investment Adviser and an affiliate. The Board assesses the nature, scope and quality of the services provided to the Fund by the personnel of the Investment Adviser, the sub-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 Fund 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, including the sub-adviser. Among the matters considered are: (a) fees (in addition to management fees) paid to the Investment Adviser and its affiliates by the Fund, such as transfer agency fees and fees for marketing and distribution; (b) Fund operating expenses paid to third parties; (c) the resources devoted to and compliance reports relating to the Fund'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 generally 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 Directors In the period prior to the Board meeting to consider renewal of the Investment Advisory Agreement and the sub-advisory agreement, the Board requests and receives materials specifically relating to the Fund's Investment Advisory Agreement and/or the sub-advisory agreement. These materials include (a) information compiled by Lipper Inc. ("Lipper") on the fees and expenses and the investment performance of the Fund as compared to a comparable group of funds as classified by Lipper; (b) sales and redemption data for the Fund; (c) a discussion by the Fund's portfolio management team of investment strategies used by the Fund during its most recent fiscal year; (d) information on the profitability to the Investment Adviser and its affiliates of the Investment Advisory Agreement, the sub-advisory agreement and other relationships with the Fund; and (e) information provided by the Investment Adviser concerning investment advisory fees charged to other clients, such as offshore funds with similar investment mandates and generally to institutional clients. 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 Fund shares, services related to the valuation and pricing of Fund portfolio holdings, allocation of Fund brokerage fees (including the related benefits to the Investment Adviser of "soft dollars"), the Fund's portfolio turnover statistics, and direct and indirect benefits to the Investment Adviser and the sub-adviser and their affiliates from their relationship with the Fund. MERRILL LYNCH HEALTHCARE FUND, INC., APRIL 30, 2005 Certain Specific Renewal Data In connection with the most recent renewal of the Fund's Investment Advisory Agreement and the sub-advisory agreement in November 2004, the independent directors' 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 Fund, and the sub-adviser. The Board focused primarily on the Investment Adviser's investment advisory services and the Fund's investment performance, having concluded that the other services provided to the Fund by the Investment Adviser were satisfactory. The Board compared Fund performance - both including and excluding the effects of the Fund'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 importance to performance over relatively long periods of time, typically three to five years. The Fund's performance after fees and expenses ranked below the median of its comparable group for the one year period, above the median for the three year period and slightly below the median for the five year period. Considering these factors, the Board concluded that the Fund's performance supported the continuation of the Investment Advisory Agreement. The Investment Adviser's Personnel and Investment Process--The Board reviews at least annually the Fund'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 Fund's portfolio manager. The Board also considered the experience of the Fund's portfolio manager and noted that Mr. Schreiber has more than twenty 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 Fund'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 in its Lipper category. It also compares the Fund's total expenses to those of other, comparable funds. The Board considered the services provided to and the fees charged by the Investment Adviser to other types of clients such as offshore funds with similar investment mandates and noted that the fees charged by the Investment Adviser in those cases typically exceeded those being charged to the Fund. The Board also noted that, as a general matter, fees charged to institutional clients were lower than the fees charged to the Fund, but believed that less extensive services were being provided to such clients. While the Fund's contractual and actual management fee rates ranked above the median of the eight comparable funds classified by Lipper for the last fiscal year, the Board noted that the Fund's overall expense ratio was at the median of the comparable funds. The Board has concluded that the Fund's management fee and fee rate and overall expense ratio are reasonable compared to those of other comparable funds. Profitability--The Board considers the cost of the services provided to the Fund by the Investment Adviser, and the Investment Adviser's and its affiliates' profits relating to the management and distribution of the Fund 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 Fund and concluded that there was a reasonable basis for the allocation. The Board believes the Investment Adviser's profits are reasonable in relation to the nature and quality of services provided. Economies of Scale--The Board considered the extent to which economies of scale might be realized as the assets of the Fund increase and whether there should be changes in the management fee rate or structure in order to enable the Fund to participate in these economies of scale. While there was no evidence to date that the Fund's assets have reached a level where such economies are effectively available, the Board will continue to seek information relating to economies of scale. Conclusion After the independent directors deliberated in executive session, the entire Board, including all of the independent directors, approved the renewal of the existing Investment Advisory Agreement and sub-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.
