Semi-Annual Report April 30, 2004 [LOGO] Merrill Lynch Investment Managers MuniVest Fund II, Inc. The Benefits and Risks of Leveraging MuniVest Fund II, Inc. utilizes leveraging to seek to enhance the yield and net asset value of its Common Stock. However, these objectives cannot be achieved in all interest rate environments. To leverage, the Fund issues Preferred Stock, which pays dividends at prevailing short-term interest rates, and invests the proceeds in long-term municipal bonds. The interest earned on these investments, net of dividends to Preferred Stock, is paid to Common Stock shareholders in the form of dividends, and the value of these portfolio holdings is reflected in the per share net asset value of the Fund's Common Stock. However, in order to benefit Common Stock shareholders, the yield curve must be positively sloped; that is, short-term interest rates must be lower than long-term interest rates. At the same time, a period of generally declining interest rates will benefit Common Stock shareholders. If either of these conditions change, then the risks of leveraging will begin to outweigh the benefits. To illustrate these concepts, assume a fund's Common Stock capitalization of $100 million and the issuance of Preferred Stock for an additional $50 million, creating a total value of $150 million available for investment in long-term municipal bonds. If prevailing short-term interest rates are approximately 3% and long-term interest rates are approximately 6%, the yield curve has a strongly positive slope. The fund pays dividends on the $50 million of Preferred Stock based on the lower short-term interest rates. At the same time, the fund's total portfolio of $150 million earns the income based on long-term interest rates. Of course, increases in short-term interest rates would reduce (and even eliminate) the dividends on the Common Stock. In this case, the dividends paid to Preferred Stock shareholders are significantly lower than the income earned on the fund's long-term investments, and therefore the Common Stock shareholders are the beneficiaries of the incremental yield. However, if short-term interest rates rise, narrowing the differential between short-term and long-term interest rates, the incremental yield pickup on the Common Stock will be reduced or eliminated completely. At the same time, the market value on the fund's Common Stock (that is, its price as listed on the New York Stock Exchange) may, as a result, decline. Furthermore, if long-term interest rates rise, the Common Stock's net asset value will reflect the full decline in the price of the portfolio's investments, since the value of the fund's Preferred Stock does not fluctuate. In addition to the decline in net asset value, the market value of the fund's Common Stock may also decline. As a part of its investment strategy, the Fund may invest in certain securities whose potential income return is inversely related to changes in a floating interest rate ("inverse floaters"). In general, income on inverse floaters will decrease when short-term interest rates increase and increase when short-term interest rates decrease. Investments in inverse floaters may be characterized as derivative securities and may subject the Fund to the risks of reduced or eliminated interest payments and losses of invested principal. In addition, inverse floaters have the effect of providing investment leverage and, as a result, the market value of such securities will generally be more volatile than that of fixed-rate, tax-exempt securities. To the extent the Fund invests in inverse floaters, the market value of the Fund's portfolio and the net asset value of the Fund's shares may also be more volatile than if the Fund did not invest in such securities. As of April 30, 2004, the percentage of the Fund's total net assets invested in inverse floaters was 11.03%. Swap Agreements The Fund may also invest in swap agreements, which are over-the-counter contracts in which one party agrees to make periodic payments based on the change in market value of a specified bond, basket of bonds, or index in return for periodic payments based on a fixed or variable interest rate or the change in market value of a different bond, basket of bonds or index. Swap agreements may be used to obtain exposure to a bond or market without owning or taking physical custody of securities. 2 MUNIVEST FUND II, INC. APRIL 30, 2004 A Letter From the President Dear Shareholder For the six-month and 12-month periods ended April 30, 2004, the Lehman Brothers Municipal Bond Index posted returns of +1.19% and +2.68%, respectively. Its taxable counterpart, the Lehman Brothers Aggregate Bond Index, had returns of +1.25% and +1.82% for the same periods. Amid considerable month-to-month volatility, tax-exempt bond yields rose over the past year, although not to the same extent as 10-year U.S. Treasury yields. In all, tax-exempt securities continued to be an attractive fixed income investment alternative. As of April month-end, the Federal Reserve Board maintained its accommodative policy stance, although a better-than-expected employment report for the month of March prompted speculation that an interest rate increase could come sooner than many had expected. On April 2, 2004, the good news on the employment front - -- previously the one dim spot in an otherwise bright economic picture -- helped prompt the yield on the 10-year Treasury bond to spike nearly 25 basis points (.25%), from 3.91% to 4.15%. Market watchers continue to monitor the economic data and Federal Reserve Board language for indications of interest rate direction. If economic growth maintains its recent pace and employment figures continue to improve, many believe it is just a matter of time before interest rates move upward. Equity markets, in the meantime, gleaned support from the improving economic environment and provided attractive returns. For the six-month and 12-month periods ended April 30, 2004, the Standard & Poor's 500 Index returned +6.27% and +22.88%, respectively. Significant fiscal and monetary stimulus in 2003, including low interest rates and tax cuts, has opened the door to consumer spending, capital spending, increases in exports and long-awaited job growth. As expected, these developments have led the way to improvements in corporate earnings -- a positive for stock markets. The events and efforts of the past year leave us with a much stronger economy today. Of course, markets will always fluctuate, and there are many uncertainties -- not the least of which are geopolitical in nature -- which can translate into negative market movements. Keeping this in mind, we encourage you to revisit your portfolio and your asset allocation strategy to ensure you are well positioned to take advantage of the opportunities that lie ahead. Importantly, your financial advisor can help you develop a strategy most suitable for your circumstances through all types of market and economic cycles. 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, /s/ Terry K. Glenn Terry K. Glenn President and Director MUNIVEST FUND II, INC. APRIL 30, 2004 3 [LOGO] Merrill Lynch Investment Managers A Discussion With Your Fund's Portfolio Manager The Fund was able to outperform its Lipper category average for the period as we remained focused on enhancing yield and preserving net asset value in a volatile interest rate environment. Describe the recent market environment relative to municipal bonds. For much of the six-month period, a positive economic backdrop helped bond prices to move higher as yields, which typically move opposite of prices, declined. In early April, however, a surprisingly strong monthly employment report triggered fears that the long accommodative Federal Reserve Board might raise interest rates sooner than many had expected. As a result, bond yields rose (prices fell) sharply for the remainder of the period. At the end of April, long-term U.S. Treasury bond yields had climbed to 5.13%, representing an increase of approximately 15 basis points (.15%) over the past six months. Ten-year U.S. Treasury note yields stood at 4.30% as of period end, an increase of more than 20 basis points. Tax-exempt bond yields generally mimicked the movement of their taxable counterparts, although volatility in the municipal market was more subdued. Long-term revenue bond yields, as measured by the Bond Buyer Revenue Bond Index, rose just four basis points over the past six months. For the same period, yields on AAA-rated issues maturing in 30 years rose approximately 10 basis points to 4.93% while yields on 10-year, AAA-rated issues increased more than 16 basis points to nearly 4%, according to Municipal Market Data. The more marked increase in 10-year bond yields may be attributed to the fact that recent issuance has been heavily concentrated in the 10-year - 20-year range. The resulting supply imbalance prompted higher intermediate bond yields (and lower prices). Longer-maturity and lower-rated issues continued to benefit from more favorable supply/demand factors and, therefore, have seen less price depreciation. For the six-month period as a whole, municipal bond supply declined approximately 5% compared to the same period a year ago. While investor enthusiasm for stocks has taken some attention away from fixed income markets, overall demand for tax-exempt municipal bonds has remained positive. Recent Federal Reserve Board statistics showed that U.S. household holdings of municipal securities increased by more than $25 billion during the fourth quarter of 2003 to approximately $680 billion. In addition, data from the Investment Company Institute indicates that, in just the first three months of 2004, tax-exempt bond funds have seen net new cash flows of almost $640 million. How did the Fund perform in light of the existing market conditions? For the six-month period ended April 30, 2004, the Common Stock of MuniVest Fund II, Inc. had net annualized yields of 7.35% and 7.81%, based on a period-end per share net asset value of $14.74 and a per share market price of $13.86, respectively, and $.540 per share income dividends. During the same period, the total investment return on the Fund's Common Stock was +3.53%, based on a change in per share net asset value from $14.76 to $14.74, and assuming reinvestment of $.534 per share ordinary income dividends. For the six-month period ended April 30, 2004, the Fund's Auction Market Preferred Stock (AMPS) had average yields as follows: Series A, .84%; Series B, ..82%; and Series C, 1.05%. The Fund's return, based on net asset value, over the past six months significantly exceeded that of its comparable Lipper category of General Municipal Debt Funds (Leveraged), which had a return of +2.20% for the six months ended April 30, 2004. (Funds in this Lipper category invest primarily in municipal debt issues rated in the top four credit rating categories. These funds can be leveraged via use of debt, preferred equity and/or reverse repurchase agreements.) Recent performance has reflected the Fund's modestly defensive structure during a period of volatile interest rates. By maintaining a conservative duration slightly below that of our peers, the Fund was better equipped to weather movements in interest rates. In general, the lower the duration, the less an investment will fluctuate in value as interest rates move up or down. The Fund's position in lower-rated issues also helped to limit asset price volatility, as these issues tend to be less interest rate-sensitive than higher-rated obligations. The incremental yield associated with these lower-rated issues also has continued to enhance the Fund's coupon income stream well above the average of its peers. 4 MUNIVEST FUND II, INC. APRIL 30, 2004 For a description of the Fund's total investment return based on a change in the per share market value of the Fund's Common Stock (as measured by the trading price of the Fund's shares on the New York Stock Exchange), and assuming reinvestment of dividends, please refer to the Financial Highlights section included in this report. As a closed-end fund, the Fund's shares may trade in the secondary market at a premium or discount to the Fund's net asset value. As a result, total investment returns based on changes in the market value of the Fund's Common Stock can vary significantly from total investment return based on changes in the Fund's net asset value. What changes were made to the portfolio during the period? Portfolio activity was somewhat restricted, as recent municipal bond issuance has been dominated by large, high-quality underwritings. As mentioned earlier, these large issues have been heavily weighted in the 10-year - 20-year maturity range to more closely align with individual retail investor interest. We have found the relatively low yields associated with these issues to be unappealing compared to the Fund's existing holdings. Instead, we continued to add lower-quality bonds to the portfolio whenever they were attractively priced. The resultant level of income generated by these bonds allowed the Fund to enhance its returns during the period. Another opportunity we sought to capitalize on was the heavy supply and relatively low price of California bonds. The state's recent fiscal problems have afforded us an opportunity to add attractively priced state-backed issues to the Fund's holdings. In fact, we increased the portfolio's exposure to California-related credits by approximately 5% during the period, bringing the Fund's allocation to approximately 8.5% of net assets. As the state resolves its recent financial problems, we expect these issues to outperform the broader municipal market, benefiting Fund performance as a result. In terms of leverage, the Fund's borrowing costs remained around 1% throughout most of the six-month period. These attractive funding levels, in combination with the steep municipal yield curve, continued to generate significant income to the Fund's Common Stock shareholders. The Federal Reserve Board appears poised to begin raising short-term interest rates, most likely later in 2004. The increase, however, is expected to be gradual and should not have a material impact on the positive advantage leverage has had on the Fund's Common Stock yield. However, should the spread between short-term and long-term interest rates narrow, the benefits of leveraging will decline and, as a result, reduce the yield on the Fund's Common Stock. At the end of the period, the Fund's leverage amount, due to AMPS, was 31.47% of total assets. (For a more complete explanation of the benefits and risks of leveraging, see page 2 of this report to shareholders.) How would you characterize the Fund's position at the close of the period? We ended the period in a slightly defensive stance with respect to interest rates. We believe this positioning readies the Fund to perform better in stable to slightly rising interest rate environments. We would expect to adopt a more defensive stance when interest rates decline during periods of market volatility. The Fund was fully invested at period-end in an effort to enhance investment income flows. With short-term cash equivalents yielding only approximately 1%, the performance penalty for holding assets in cash reserves is far too severe. We continue to favor higher-couponed, lower-rated issues over more interest rate-sensitive current-couponed issues. With economic growth expected to continue its moderate advance, long-term interest rates are likely to begin reversing their recent declines. The timing of this reversal, however, remains unclear. We believe the Federal Reserve Board will want to see consistent, strong employment growth before it will consider raising short-term interest rates. Such a move is not probable until later this year. In any case, given consensus inflationary forecasts, any increase in long-term interest rates is likely to be moderate. With all of this is mind, and considering expectations for manageable new-issue volume in 2004, we believe the municipal market is poised to provide attractive returns compared to the taxable bond market regardless of the interest rate environment.

See Notes to Financial Statements. 16 MUNIVEST FUND II, INC. APRIL 30, 2004 Notes to Financial Statements 1. Significant Accounting Policies: MuniVest Fund II, Inc. (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a non-diversified, closed-end management investment company. The Fund's financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, 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 a fair statement of the results for the interim period presented. All such adjustments are of a normal, recurring nature. The Fund determines and makes available for publication the net asset value of its Common Stock on a weekly basis. The Fund's Common Stock is listed on the New York Stock Exchange under the symbol MVT. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments -- Municipal bonds are traded primarily in the over-the-counter markets and are valued at the last available bid price in the over-the-counter market or on the basis of yield equivalents as obtained by the Fund's pricing service from one or more dealers that make markets in such securities. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their closing prices as of the close of such exchanges. Options written or purchased are valued at the last sale price in the case of exchange-traded options. In the case of options traded in the over-the-counter market, valuation is the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued by quoted fair values received daily by the Fund from the counterparty. Short-term investments with a remaining maturity of sixty days or less are valued at amortized cost, which approximates market value. 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 a pricing service retained by the Fund, which may utilize a matrix system for valuations. The procedures of the pricing service and its valuations are reviewed by the officers of the Fund under the general supervision of the Board of Directors. (b) 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. o 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. o Options -- The Fund may write covered call options and purchase 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. MUNIVEST FUND II, INC. APRIL 30, 2004 17 [LOGO] Merrill Lynch Investment Managers Notes to Financial Statements (continued) o Forward interest rate swaps -- The Fund may enter into forward interest rate swaps. In a forward interest rate swap, the Fund and the counterparty agree to make periodic net payments on a specified notional contract amount, commencing on a specified future effective date, unless terminated earlier. When the agreement is closed, the Fund records a realized gain or loss in an amount equal to the value of the agreement. (c) 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. (d) 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. Interest income is recognized on the accrual basis. The Fund amortizes all premiums and discounts on debt securities. (e) Dividends and distributions -- Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. FAM 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 the six months ended April 30, 2004, FAM reimbursed the Fund in the amount of $6,755. In addition, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, received $4,000 in commissions on the execution of portfolio security transactions for the Fund for the six months ended April 30, 2004. For the six months ended April 30, 2004, the Fund reimbursed FAM $4,426 for certain accounting services. Certain officers and/or directors of the Fund are officers and/or directors of FAM, PSI, and/or ML & Co. 3.

Stock Transactions: The Fund is authorized to issue 200,000,000 shares of stock, including Preferred Stock, par value $.10 per share, all of which were initially classified as Common Stock. The Board of Directors is authorized, however, to reclassify any unissued shares of stock without approval of holders of Common Stock. Common Stock Shares issued and outstanding during the six months ended April 30, 2004 increased by 37,664 as a result of dividend reinvestment and for the year ended October 31, 2003 remained constant. Preferred Stock Auction Market Preferred Stock are shares of Preferred Stock of the Fund, with a par value of $.05 per share and a liquidation preference of $25,000 per share plus accrued and unpaid dividends, that entitle their holders to receive cash dividends at an annual rate that may vary for the successive dividend periods. The yields in effect at April 30, 2004 were as follows: Series A, .90%; Series B, .93%; and Series C, .98%. 18 MUNIVEST FUND II, INC. APRIL 30, 2004 Notes to Financial Statements (concluded) The Fund pays commissions to certain broker-dealers at the end of each auction at an annual rate ranging from .25% to .375%, calculated on the proceeds of each auction.

APRIL 30, 2004 23 [LOGO] Merrill Lynch Investment Managers www.mlim.ml.com MuniVest Fund II, Inc. seeks to provide shareholders with as high a level of current income exempt from Federal income taxes as is consistent with its investment policies and prudent investment management by investing primarily in a portfolio of long-term, investment grade municipal obligations the interest on which, in the opinion of bond counsel to the issuer, is exempt from Federal income taxes. This report, including the financial information herein, is transmitted to shareholders of MuniVest Fund II, Inc. for their information. It is not a prospectus. Past performance results shown in this report should not be considered a representation of future performance. The Fund has leveraged its Common Stock and intends to remain leveraged by issuing Preferred Stock to provide the Common Stock shareholders with a potentially higher rate of return. Leverage creates risks for Common Stock shareholders, including the likelihood of greater volatility of net asset value and market price of shares of the Common Stock, and the risk that fluctuations in the short-term dividend rates of the Preferred Stock may affect the yield to Common Stock shareholders.
