Dividend Policy The Fund's dividend policy is to distribute all or a portion of its net investment income to its shareholders on a monthly basis. In order to provide shareholders with a more stable level of dividend distributions, the Fund may at times pay out less than the entire amount of net investment income earned in any particular month and may at times in any particular month pay out such accumulated but undistributed income in addition to net investment income earned in that month. As a result, the dividends paid by the Fund for any particular month may be more or less than the amount of net investment income earned by the Fund during such month. The Fund's current accumulated but undistributed net investment income, if any, is disclosed in the Statement of Net Assets, which comprises part of the financial information included in this report. 2 MUNIVEST FUND II, INC. APRIL 30, 2006 A Letter From the President Dear Shareholder You may be aware that changes are on the horizon at Merrill Lynch Investment Managers ("MLIM"). On February 15, 2006, Merrill Lynch announced plans to combine the firm's investment advisory business, including MLIM, with another highly regarded investment manager -- BlackRock, Inc. ("BlackRock"). We believe this merger of asset management strength will benefit our investors. MLIM is a leading investment management organization with over $576 billion in assets under management globally and 2,757 employees in 17 countries. It offers over 100 investment strategies in vehicles ranging from mutual funds to institutional portfolios. BlackRock is one of the largest publicly traded investment management firms in the United States with $463.1 billion in assets under management and 1,839 employees. It manages assets on behalf of institutional and individual investors worldwide through a variety of equity, fixed income, liquidity and alternative investment products. At the completion of the transaction, which is expected in the third quarter of this year, the resultant firm will be a top-10 investment manager worldwide with over $1 trillion in assets under management.* The combined company will provide a wider selection of high-quality investment solutions across a range of asset classes and investment styles. MLIM and BlackRock possess complementary capabilities that together create a well-rounded organization uniting some of the finest money managers in the industry. At the same time, the firms share similar values and beliefs -- they are focused on delivering excellence on behalf of clients, and both make investment performance their single most important mission. In short, the merger only reinforces our commitment to shareholders. Most of MLIM's investment products -- including mutual funds, separately managed accounts, annuities and variable insurance funds -- eventually will carry the "BlackRock" name. As a shareholder in one or more MLIM-advised mutual funds, you will receive a proxy package in the coming weeks in connection with this transaction. After you receive this information, should you have any questions or concerns, do not hesitate to contact your financial advisor. As always, we thank you for entrusting us with your investment assets, and we look forward to continuing to serve your investment needs with even greater strength and scale as the new BlackRock. Sincerely, /s/ Robert C. Doll, Jr. Robert C. Doll, Jr. President and Chief Investment Officer Merrill Lynch Investment Managers * $1.039 trillion in assets under management as of March 31, 2006. Data, including assets under management, are as of March 31, 2006. MUNIVEST FUND II, INC. APRIL 30, 2006 3 A Discussion With Your Fund's Portfolio Manager The Fund maintained an above-average distribution rate throughout the period, and our commitment to providing shareholders with attractive income continues to drive portfolio activity. Describe the recent market environment relative to municipal bonds. Long-term bond yields rose sharply during the six-month period ended April 30, 2006, with much of the increase occurring in March and April 2006. Bond prices, which move opposite of yields, declined. Bond prices were pressured as investors focused on solid economic growth, both globally and in the United States, and renewed inflationary pressures deriving from rising commodity prices. First quarter 2006 gross domestic product growth was recently estimated at 4.8%, well above the 1.7% rate recorded in the fourth quarter of 2005. The Federal Reserve Board (the Fed) continued to raise short-term interest rates at each of its meetings during the period, bringing the federal funds target rate to 4.75% at period-end, and to 5% on May 10. In response, the Treasury curve continued to flatten, with short-term interest rates rising more than longer-term interest rates. Over the past six months, 30-year U.S. Treasury bond yields rose 41 basis points (.41%) to 5.17% and 10-year U.S. Treasury note yields rose 50 basis points to 5.07%, the highest level since May 2002. While the municipal yield curve also flattened during the period, the market's strong technical position provided significant price support. This allowed municipal bond prices to improve slightly or decline much less than those of their taxable counterparts. As measured by Municipal Market Data, yields on AAA-rated issues maturing in 30 years fell six basis points to 4.53%, while yields on AAA-rated issues maturing in 10 years rose 16 basis points to 4.08%. For the most part, the tax-exempt market's recent outperformance has been fostered by a dramatic decline in new bond issuance so far in 2006. In 2005, more than $408 billion in new long-term tax-exempt bonds was underwritten, a new annual record and an increase of more than 13% compared to 2004. Over the past six months, $170 billion in long-term municipal bonds was issued, a decline of 8.6% versus the same period a year earlier. The record new issuance in 2005 was largely triggered by a 47% increase in refunding activity as issuers took advantage of historically low bond yields and a flattening yield curve to refinance outstanding higher-couponed debt. Year-to-date through April 2006, refunding issuance declined more than 55% relative to the first four months of 2005. This decline already has led some analysts to reduce their forecasts for 2006 new issuance from the $350 billion - $370 billion range to the $300 billion - - $325 billion range. Lower annual issuance would further solidify the tax-exempt market's already positive technical position. The tax-exempt market has continued to enjoy strong investor demand. As reported by the Investment Company Institute, long-term municipal bond funds received net new monies of $5.0 billion in 2005 -- a sharp reversal from the $3.7 billion outflow in 2004. During the first quarter of 2006, tax-exempt mutual funds received over $9.3 billion, slightly higher than the $8.9 billion inflow during the same period in 2005. Recent statistics from AMG Data Services indicate that, thus far in 2006, weekly cash flows into long-term municipal bond funds averaged over $300 million, a significant improvement from the weekly average of $65 million in December 2005. Looking ahead, the fundamentals for the tax-exempt bond market appear favorable, and continued positive cash flows are anticipated. Given their attractive yields relative to comparable U.S. Treasury bonds, and the prospects for reduced issuance in 2006, we believe municipal bonds could enjoy solid results in the coming months. How did the Fund perform during the period in light of the existing market conditions? For the six-month period ended April 30, 2006, the Common Stock of MuniVest Fund II, Inc. had net annualized yields of 7.03% and 6.54%, based on a period-end per share net asset value of $14.97 and a per share market price of $16.09, respectively, and $.522 per share income dividends. Over the same period, the total investment return on the Fund's Common Stock was +2.43%, based on a change in per share net asset value from $15.13 to $14.97, and assuming reinvestment of all distributions. The Fund's total return, based on net asset value, lagged the +2.60% average return of its comparable Lipper category of General Municipal Debt Funds (Leveraged). (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.) 4 MUNIVEST FUND II, INC. APRIL 30, 2006 Fund performance benefited from our neutral interest rate exposure and the strong performance of its lower-rated holdings, which continued to outpace the broader market during the six-month period. These lower-rated securities also greatly contributed to the Fund's attractive distribution yield. The modest underperformance on a total return basis is largely attributable to the portfolio's considerable exposure to the intermediate sector of the municipal yield curve, an area that underperformed as the curve flattened. The Fund's exposure to the intermediate sector primarily results from both its derivative position and the natural maturation of the portfolio. That is, as time progresses, many of the Fund's holdings are prerefunded to shorter call dates while other issues become priced to shorter and shorter call dates, resulting in the increased exposure to intermediate maturities. Nevertheless, we retained many of these bonds in the portfolio, as they provide a meaningful income benefit and their sale could result in material taxable gains as well as declines in the Fund's dividend stream. 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 of 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 returns based on changes in the Fund's net asset value. What changes were made to the portfolio during the period? Given the aforementioned decline in new issuance during the past six months, attractive trading opportunities have been limited. Portfolio activity has been largely focused on the reinvestment of coupon income and the proceeds from bond calls. In terms of new purchases, we have recently targeted AA-rated and A-rated revenue bonds, particularly in New York where new issuance trends have been consistently stronger than national levels. The Fund's overall credit quality profile remained essentially unchanged during the period, with more than 56% of the portfolio's net assets rated A or higher at April month-end. For the six-month period ended April 30, 2006, the Fund's Auction Market Preferred Stock (AMPS) had average yields of 3.02% for Series A, 3.40% for Series B, 3.01% for Series C and 3.01% for Series D. The Fed raised the short-term interest rate target 100 basis points during the period, and this continued to affect the Fund's borrowing costs. We would expect additional increases in the cost of funds to be more limited as the Fed nears a pause in its monetary tightening campaign. Despite interest rate increases during the period, the tax-exempt yield curve maintained a positive slope, allowing us to borrow at a lower rate than where we invest. This continued to generate an income benefit to the holders of Common Stock from the leveraging of Preferred Stock. 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 36.72% of total net assets, before the deduction of Preferred Stock. (For a more complete explanation of the benefits and risks of leveraging, see page 6 of this report to shareholders.) How would you characterize the Fund's position at the close of the period? We recently adopted a more positive stance on the municipal market. After 16 consecutive interest rate hikes, the Fed may be nearing a pause in its monetary tightening campaign. We would expect the end of Fed tightening, combined with modest economic growth and muted inflationary pressures, to promote a gradual improvement in tax-exempt bond prices later this year, underpinning our more constructive outlook. Conversely, we would view accelerated economic activity and/or rising wage pressures as signals to return to a more defensive positioning. Overall, we intend to maintain the Fund's fully invested stance as we seek to enhance shareholder income. Portfolio activity in the months ahead is likely to be driven by our efforts to maintain the Fund's already attractive distribution yield. Fred K. Stuebe Vice President and Portfolio Manager May 12, 2006 MUNIVEST FUND II, INC. APRIL 30, 2006 5 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. 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, 2006, the percentage of the Fund's total net assets invested in inverse floaters was 10.70%, before the deduction of Preferred Stock. Swap Agreements The Fund may 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. Swap agreements involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the other party to the agreement. 6 MUNIVEST FUND II, INC.

See Notes to Financial Statements. 16 MUNIVEST FUND II, INC. APRIL 30, 2006 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 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 determines and makes available for publication the net asset value of its Common Stock on a daily basis. The Fund's Common Stock shares are 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 ("OTC") markets and are valued at the last available bid price in the OTC market or on the basis of values as obtained by a pricing service. Pricing services use valuation matrixes that incorporate both dealer-supplied valuations and valuation models. The procedures of the pricing service and its valuations are reviewed by the officers of the Fund under the general direction of the Board of Directors. Such valuations and procedures are reviewed periodically by the Board of Directors of the Fund. 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 OTC 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's pricing service. Short-term investments with a remaining maturity of 60 days or less are valued at amortized cost, which approximates market value, under which method the investment is valued at cost and any premium or discount is amortized on a straight line basis to maturity. Investments in open-end investment companies are valued at their net asset value each business day. Securities and other 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. (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. 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. MUNIVEST FUND II, INC. APRIL 30, 2006 17 Notes to Financial Statements (continued) (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. (f) Offering costs -- Direct expenses relating to the public offering of the Fund's Preferred Stock were charged to capital at the time of issuance of the shares. 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 such services, the Fund pays a monthly fee at an annual rate of .50% of the Fund's average weekly net assets, including proceeds from the issuance of Preferred Stock. The Investment Adviser has agreed to reimburse its management fee by the amount of the management fees the Fund pays to FAM indirectly through its investment in Merrill Lynch Institutional Tax-Exempt Fund. For the six months ended April 30, 2006, FAM reimbursed the Fund in the amount of $250. In addition, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, received $1,000 in commissions on the execution of portfolio security transactions for the Fund for the six months ended April 30, 2006. For the six months ended April 30, 2006, the Fund reimbursed FAM $5,098 for certain accounting services. Certain officers and/or directors of the Fund are officers and/or directors of FAM, PSI, and/or ML & Co. In February 2006, ML & Co. and BlackRock, Inc. entered into an agreement to contribute ML & Co.'s investment management business, including FAM, to the investment management business of BlackRock, Inc. The transaction is expected to close in the third quarter of 2006. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the six months ended April 30, 2006 were $160,657,088 and $161,610,110, respectively. 4. 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, 2006 and the year ended October 31, 2005 increased by 64,795 and 126,778 as a result of dividend reinvestment, respectively. Preferred Stock Auction Market Preferred Stock are shares of Preferred Stock of the Fund, with a par value of $.05 per share on Series A Shares, Series B Shares and Series C Shares, and $.10 per share on Series D Shares. In addition, there is 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, 2006 were as follows: Series A, 3.20%; Series B, 3.37%; Series C, 3.33%; and Series D, 3.75%. 18 MUNIVEST FUND II, INC. APRIL 30, 2006 Notes to Financial Statements (concluded) Shares issued and outstanding during the six months ended April 30, 2006 remained constant. Shares issued and outstanding during the year ended October 31, 2005 increased by 1,600 shares from the issuance of an additional series of Preferred Stock. 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. For the six months ended April 30, 2006, MLPF&S earned $119,678 as commissions. 5. Capital Loss Carryforward: On October 31, 2005, the Fund had a net capital loss carryforward of $12,488,454, of which $3,730,020 expires in 2007 and $8,758,434 expires in 2008. This amount will be available to offset like amounts of any future taxable gains. 6. Subsequent Event: The Fund paid a tax-exempt income dividend to holders of Common Stock in the amount of $.086000 per share on May 30, 2006 to shareholders of record on May 15, 2006.

APRIL 30, 2006 [LOGO] Merrill Lynch Investment Managers www.mlim.ml.com - -------------------------------------------------------------------------------- Mercury Advisors A Division of Merrill Lynch Investment Managers www.mercury.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. Statements and other information herein are as dated and are subject to change.
