OCTOBER 31, 2008 A Letter to Shareholders Dear Shareholder It has been a tumultuous period for investors, marked by almost daily headlines of deepening turmoil in financial markets and a darkening economic outlook. The news took an extraordinarily heavy tone late in the period as the credit crisis boiled over and triggered unprecedented failures and consolidation in the financial sector, stoking fears of a market and economic collapse and prompting a series of new government programs designed to contain and combat the fallout. The Federal Reserve Board (the "Fed") has taken decisive measures to restore liquidity and stabilize the financial system. Key moves included slashing the target federal funds rate 250 basis points (2.50%) between November 2007 and April 2008 and providing massive cash injections and lending programs. In October, as credit conditions further deteriorated, the central bank cut the key interest rate by 50 basis points on two separate occasions -- on October 8 in coordination with five other global central banks, and again during its regularly scheduled meeting on October 29. This left the key short-term rate at just 1.0%, its lowest level since 2004. While the U.S. economy appeared fairly resilient through the second quarter of 2008, the third quarter saw a contraction of 0.5%, and a more significant decline is expected for the fourth quarter. Moreover, on December 1, the National Bureau of Economic Research confirmed that the U.S. had entered a recession in December 2007. Against this backdrop, U.S. equity markets experienced intense volatility, with periods of downward pressure punctuated by sharp rebounds. Losses were significant and broad-based, though small-cap stocks fared moderately better than their larger counterparts. Non-U.S. markets decelerated at a considerably faster pace than domestic equities -- a stark reversal of recent years' trends, when international stocks generally outpaced U.S. stocks. Treasury issues also traded in a volatile fashion, but rallied overall (yields fell and prices correspondingly rose) and outperformed other fixed income assets as investors continued their flight to higher quality and more liquid securities. Tax-exempt issues generally underperformed, as problems among municipal bond insurers and the collapse in the market for auction rate securities afflicted the group throughout the course of the past year. At the same time, the above mentioned economic headwinds and malfunctioning credit markets plagued the high yield sector, with the third quarter of 2008 marking one of the worst periods in history for the asset class. Facing unprecedented volatility and macro pressures, the major benchmark indexes generally recorded losses for the six- and 12-month reporting periods: Total Returns as of October 31, 2008 6-month 12-month ============================================================================================================== U.S. equities (S&P 500 Index) (29.28)% (36.10)% - -------------------------------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) (24.39) (34.16) - -------------------------------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) (41.21) (46.62) - -------------------------------------------------------------------------------------------------------------- Fixed income (Barclays Capital U.S. Aggregate Index*) (3.63) 0.30 - -------------------------------------------------------------------------------------------------------------- Tax-exempt fixed income (Barclays Capital Municipal Bond Index*) (4.70) (3.30) - -------------------------------------------------------------------------------------------------------------- High yield bonds (Barclays Capital U.S. Corporate High Yield 2% Issuer Capped Index*) (24.86) (25.41) - -------------------------------------------------------------------------------------------------------------- * Formerly a Lehman Brothers Index.

OCTOBER 31, 2008 3 Fund Summary as of October 31, 2008 Investment Objective BlackRock MuniVest Fund II, Inc. (MVT) (the "Fund") 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 issuers, is exempt from federal income taxes. Performance For the 12 months ended October 31, 2008, the Fund returned (25.18)%, based on market price and (19.33)% based on net asset value ("NAV"). For the same period, the closed-end Lipper Insured Municipal Debt Funds (Leveraged) category posted an average return of (14.93)% on a NAV basis. All returns reflect reinvestment of dividends. The Fund's discount to NAV, which widened during the period, accounts for the difference between performance based on price and performance based on NAV. The Fund maintained a relatively neutral duration exposure for much of the period. Fund underperformance resulted from the widening of credit spreads, as prices on the Fund's lower-rated holdings fell significantly more than higher-rated municipal bonds. These lower-rated bonds, however, have continued to generate substantial income for the Fund, allowing it to distribute a well-above-average dividend yield. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results. Fund Information Symbol on New York Stock Exchange .............................

OCTOBER 31, 2008 The Benefits and Risks of Leveraging The Fund may utilize leverage to seek to enhance the yield and NAV of its Common Shares. However, these objectives cannot be achieved in all interest rate environments. To leverage, the Fund issues Preferred Shares, which pay dividends at prevailing short-term interest rates, and invests the proceeds in long-term municipal bonds. In general, the concept of leveraging is based on the premise that the cost of assets to be obtained from leverage will be based on short-term interest rates, which normally will be lower than the income earned by the Fund on its longer-term portfolio investments. To the extent that the total assets of the Fund (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, the Fund's Common Shareholders will benefit from the incremental yield. To illustrate these concepts, assume the Fund's Common Shares capitalization is $100 million and it issues Preferred Shares 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 3% and long-term interest rates are 6%, the yield curve has a strongly positive slope. In this case, the Fund pays dividends on the $50 million of Preferred Shares 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. Conversely, if prevailing short-term interest rates rise above long-term interest rates of 6%, the yield curve has a negative slope. In this case, the Fund pays dividends on the higher short-term interest rates whereas the Fund's total portfolio earns income based on lower long-term interest rates. In this case, the dividends paid to Preferred Shareholders are significantly lower than the income earned on the Fund's long-term investments, and therefore the Common 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 Shares will be reduced or eliminated completely. Furthermore, the value of the Fund's portfolio investments generally varies inversely with the direction of long-term interest rates, although other factors can influence the value of portfolio investments. In contrast, the redemption value of the Fund's Preferred Shares does not fluctuate in relation to interest rates. As a result, changes in interest rates can influence the Fund's NAV positively or negatively in addition to the impact on Fund performance from leverage from Preferred Shares discussed above. The Fund may also, from time to time, leverage its assets through the use of tender option bond ("TOB") programs, as described in Note 1 of the Notes to Financial Statements. TOB investments generally will provide the Fund with economic benefits in periods of declining short-term interest rates, but expose the Fund to risks during periods of rising short-term interest rates similar to those associated with Preferred Shares issued by the Fund, as described above. Additionally, fluctuations in the market value of municipal securities deposited into the TOB trust may adversely affect the Fund's NAV per share. The use of leverage may enhance opportunities for increased returns to the Fund and Common Shareholders, but as described above, it also creates risks as short- or long-term interest rates fluctuate. Leverage also will generally cause greater changes in a Fund's NAV, market price and dividend rate than a comparable portfolio without leverage. If the income derived from securities purchased with assets received from leverage exceeds the cost of leverage, the Fund's net income will be greater than if leverage had not been used. Conversely, if the income from the securities purchased is not sufficient to cover the cost of leverage, the Fund's net income will be less than if leverage had not been used, and therefore the amount available for distribution to Common Shareholders will be reduced. The Fund may be required to sell portfolio securities at inopportune times or below fair market values in order to comply with regulatory requirements applicable to the use of leverage or as required by the terms of leverage instruments, which may cause a Fund to incur losses. The use of leverage may limit a Fund's ability to invest in certain types of securities or use certain types of hedging strategies, such as in the case of certain restrictions imposed by ratings agencies that rate preferred shares issued by the Fund. The Fund will incur expenses in connection with the use of leverage, all of which are borne by the holders of the Common Shares and may reduce returns on the Common Shares. Under the Investment Company Act of 1940, the Fund is permitted to issue Preferred Shares in an amount of up to 50% of its total managed assets at the time of issuance. Under normal circumstances, the Fund anticipates that the total economic leverage from Preferred Shares and TOBs will not exceed 50% of its total managed assets at the time such leverage is incurred. As of October 31, 2008, the Fund had leverage from Preferred Shares and TOBs of 47% of its total managed assets. Derivative Instruments The Fund may invest in various derivative instruments, including swap agreements and futures, and other instruments specified in the Notes to Financials Statements, which constitute additional forms of economic leverage. Such instruments are used to obtain exposure to a market without owning or taking physical custody of securities or to hedge market and/or interest rate risks. Such derivative instruments involve risks, including the imperfect correlation between the value of a derivative instrument and the underlying asset, possible default of the other party to the transaction and illiquidity of the derivative instrument. The Fund's ability to successfully use a derivative instrument depends on the Advisor's ability to accurately predict pertinent market movements, which cannot be assured. The use of derivative instruments may result in losses greater than if they had not been used, may require the Fund to sell or purchase portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the Fund can realize on an investment or may cause the Fund to hold a security that it might otherwise sell. The Fund's investments in these instruments are discussed in detail in the Notes to Financial Statements. BLACKROCK MUNIVEST FUND II, INC.

See Notes to Financial Statements. BLACKROCK MUNIVEST FUND II, INC. OCTOBER 31, 2008 13 Notes to Financial Statements 1. Organization and Significant Accounting Policies: BlackRock MuniVest Fund II, Inc. (the "Fund") is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as a non-diversified, closed-end management investment company. The Fund is organized as a Maryland corporation. 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. The Fund determines and makes available for publication the net asset value of its Common Shares on a daily basis. The following is a summary of significant accounting policies followed by the Fund: Valuation of investments: Municipal investments (including commitments to purchase such investments on a "when-issued" basis) are valued on the basis of prices provided by dealers or pricing services selected under the supervision of the Fund's Board of Directors (the "Board"). In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrixes, market transactions in comparable investments and information with respect to various relationships between investments. Financial futures contracts traded on exchanges are valued at their last sale price. Swap agreements are valued utilizing quotes received daily by the Fund's pricing service or through brokers. Short-term securities are valued at amortized cost. In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the market value of such investment, the investment will be valued by a method approved by the Board as reflecting fair value ("Fair Value Assets"). When determining the price for Fair Value Assets, the investment advisor and/or sub-advisor seeks to determine the price that the Fund might reasonably expect to receive from the current sale of that asset in an arm's-length transaction. Fair value determinations shall be based upon all available factors that the investment advisor and/or sub-advisor deems relevant. The pricing of all Fair Value Assets is subsequently reported to the Board or a committee thereof. 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 if the value of the contract decreases due to an unfavorable change in the price of the underlying security 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 financial futures contracts for investment purposes or to manage its interest rate risk. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. 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 margin variation and are recognized 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. The use of futures transactions involves the risk of an imperfect correlation in the movements in the price of futures contracts, interest rates and the underlying assets, and the possible inability of counterparties to meet the terms of their contracts. o Forward interest rate swaps -- The Fund may enter into forward interest rate swaps for investment purposes. 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. Forward interest rate swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). When the forward interest rate swap is terminated, the Fund will record a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Fund's basis in the contract, if any. Forward interest rate swap transactions involve, to varying degrees, elements of credit and market risk in excess of the amounts recognized on the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions. The Fund generally intends to close each forward interest rate swap before the effective date specified in the agreement and therefore avoid entering into the interest rate swap underlying each forward interest rate swap. Forward Commitments and When-Issued Delayed Delivery Securities: The Fund may purchase securities on a when-issued basis and may purchase or sell securities on a forward commitment basis. Settlement of such transactions normally occurs within a month or more after the purchase or sale commitment is made. The Fund may purchase securities under such conditions only with the intention of actually acquiring them, but may enter into a separate agreement to sell the securities before the settlement date. Since the value of securities purchased may fluctuate prior to settlement, the Fund may be required to pay more at settlement than the security is worth. In addition, the purchaser is not entitled to any of the interest earned prior to settlement. When purchasing a security on a delayed-delivery basis, the Fund assumes the rights and risks of ownership of the security, including the risk of price and yield fluctuations. 14 BLACKROCK MUNIVEST FUND II, INC. OCTOBER 31, 2008 Notes to Financial Statements (continued) Municipal Bonds Transferred to Tender Option Bond Trusts: The Fund may leverage its assets through the use of tender option bond trusts ("TOBs"). A TOB is established by a third party sponsor forming a special purpose entity, into which one or more funds, or an agent on behalf of the funds, transfers municipal securities. Other funds managed by the investment advisor may also contribute municipal securities to a TOB into which the Fund has contributed securities. A TOB typically issues two classes of beneficial interests: short-term floating rate certificates, which are sold to third party investors, and residual certificates ("TOB Residuals"), which are generally issued to the participating funds that made the transfer or to affiliates of the Fund. The TOB Residuals held by the Fund include the right of the Fund (1) to cause the holders of a proportional share of the floating rate certificates to tender their certificates at par, and (2) to transfer, within seven days, a corresponding share of the municipal securities from the TOB to the Fund. The cash received by the TOB from the sale of the short-term floating rate certificates, less transaction expenses, is paid to the Fund, which typically invests the cash in additional municipal securities. The Fund's transfer of the municipal securities to a TOB is accounted for as a secured borrowing, therefore the municipal securities deposited into a TOB are presented in the Fund's Schedule of Investments and the proceeds from the transaction are reported as a liability for Trust certificates. Interest income from the underlying security is recorded by the Fund on an accrual basis. Interest expense incurred on the secured borrowing and other expenses related to remarketing, administration and trustee services to a TOB are reported as expenses of the Fund. The floating rate certificates have interest rates that generally reset weekly and their holders have the option to tender certificates to the TOB for redemption at par at each reset date. At October 31, 2008, the aggregate value of the underlying municipal securities transferred to TOBs was $87,235,135, the related liability for trust certificates was $49,617,552 and the range of interest rates was 2.479% to 4.475%. Financial transactions executed through TOBs generally will underperform the market for fixed rate municipal bonds when short-term interest rates rise, but tend to outperform the market for fixed rate bonds when interest rates decline or remain relatively stable. Should short-term interest rates rise, the Fund's investment in TOBs likely will adversely affect the Fund's investment income and dividends to Common Shareholders. Fluctuations in the market value of municipal securities deposited into the TOB may adversely affect the Fund's net asset value per share. Segregation and Collateralization: In cases in which the 1940 Act and the interpretive positions of the Securities and Exchange Commission ("SEC") require that the Fund segregate assets in connection with certain investments (e.g., when-issued delayed delivery securities, swaps and futures), the Fund will, consistent with certain interpretive letters issued by the SEC, designate on its books and records cash or other liquid securities having a market value at least equal to the amount that would otherwise be required to be physically segregated. Furthermore, based on requirements and agreements with certain exchanges and third party broker-dealers, the Fund may also be required to deliver or deposit securities as collateral for certain investments (e.g., swaps). Investment Transactions and Investment Income: Investment 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 date. Interest income is recognized on the accrual method. The Fund amortizes all premiums and discounts on debt securities. Dividends and Distributions: Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. Dividends and distributions to holders of Preferred Shares are accrued and determined as described in Note 4. 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 provisions are required. Effective April 30, 2008, the Fund implemented Financial Accounting Standards Board ("FASB") Interpretation No. 48, "Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109" ("FIN 48"). FIN 48 prescribes the minimum recognition threshold a tax position must meet in connection with accounting for uncertainties in income tax positions taken or expected to be taken by an entity, including investment companies, before being measured and recognized in the financial statements. The investment advisor has evaluated the application of FIN 48 to the Fund, and has determined that the adoption of FIN 48 does not have a material impact on the Fund's financial statements. The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund's U.S. federal tax returns remains open for the years ended October 31, 2005 through October 31, 2007. The statutes of limitations on the Fund's state and local tax returns may remain open for an additional year depending upon the jurisdiction. Recent Accounting Pronouncements: In September 2006, Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"), was issued and is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. The impact on the Fund's financial statements disclosures, if any, is currently being assessed. In March 2008, Statement of Financial Accounting Standards No. 161, "Disclosures about Derivative Instruments and Hedging Activities -- an amendment of FASB Statement No. 133" ("FAS 161"), was issued. FAS 161 is intended to improve financial reporting for derivative instruments by BLACKROCK MUNIVEST FUND II, INC. OCTOBER 31, 2008 15 Notes to Financial Statements (continued) requiring enhanced disclosure that enables investors to understand how and why an entity uses derivatives, how derivatives are accounted for, and how derivative instruments affect an entity's results of operations and financial position. In September 2008, FASB Staff Position No. 133-1 and FASB Interpretation No. 45-4 (the "FSP"), "Disclosures about Credit Derivatives and Certain Guarantees: An Amendment of FASB Statement No. 133 and FASB Interpretation No. 45; and Clarification of the Effective Date of FASB Statement No. 161," was issued and is effective for fiscal years and interim periods ending after November 15, 2008. The FSP amends FASB Statement No. 133, "Accounting for Derivative Instruments and Hedging Activities," to require disclosures by sellers of credit derivatives, including credit derivatives embedded in hybrid instruments. The FSP also clarifies the effective date of FAS 161, whereby disclosures required by FAS 161 are effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. The impact on the Fund's financial statement disclosures, if any, is currently being assessed. Deferred Compensation and BlackRock Closed-End Share Equivalent Investment Plan: Under the deferred compensation plan approved by the Fund's Board, non-interested Directors ("Independent Directors") defer a portion of their annual complex-wide compensation. Deferred amounts earn an approximate return as though equivalent dollar amounts have been invested in common shares of other certain BlackRock Closed-End Funds selected by the Independent Directors. This has approximately the same economic effect for the Independent Directors as if the Independent Directors had invested the deferred amounts directly in other certain BlackRock Closed-End Funds. The deferred compensation plan is not funded and obligations thereunder represent general unsecured claims against the general assets of the Fund. The Fund may, however, elect to invest in common shares of other certain BlackRock Closed-End Funds selected by the Independent Directors in order to match its deferred compensation obligations. Other: Expenses directly related to the Fund are charged to the Fund. Other operating expenses shared by several funds are pro-rated among those funds on the basis of relative net assets or other appropriate methods. 2. Investment Advisory Agreement and Other Transactions with Affiliates: The Fund entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the "Advisor"), an indirect, wholly owned subsidiary of BlackRock, Inc., to provide investment advisory and administration services. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc. are principal owners of BlackRock, Inc. The Advisor 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 the Advisor a monthly fee at an annual rate of 0.50% of the Fund's average daily net assets. Average daily net assets is the average daily value of the Fund's total assets minus the sum of its accrued liabilities. The Advisor has entered into a separate sub-advisory agreement with BlackRock Investment Management, LLC. ("BIM"), an affiliate of the Advisor, under which the Advisor pays BIM for services it provides, a monthly fee that is a percentage of the investment advisory fee paid by the Fund to the Advisor. For the year ended October 31, 2008, the Fund reimbursed the Advisor $7,622, for certain accounting services, which is included in accounting services in the Statement of Operations. Certain officers and/or directors of the Fund are officers and/or directors of BlackRock, Inc. or its affiliates. The Fund reimburses the Advisor for compensation paid to the Fund's Chief Compliance Officer. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the year ended October 31, 2008, were $227,296,446 and $285,354,746, respectively. 4. Capital Share Transactions: Common Shares The Fund is authorized to issue 200,000,000 shares of stock, including Preferred Shares, par value $0.10 per share, all of which were initially classified as Common Shares. The Board is authorized, however, to reclassify any unissued shares of stock without approval of Common Shareholders. Common Shares issued and outstanding for the years ended October 31, 2008 and October 31, 2007 increased by 104,666 and 87,529, respectively, as a result of dividend reinvestment. Preferred Shares The Preferred Shares are redeemable at the option of the Fund, in whole or in part, on any dividend payment date at $25,000 per share plus any accumulated unpaid dividends whether or not declared. The Preferred Shares are also subject to mandatory redemption at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared, if certain requirements relating to the composition of the assets and liabilities of the Fund, as set forth in the Fund's Articles Supplementary, are not satisfied. 16 BLACKROCK MUNIVEST FUND II, INC. OCTOBER 31, 2008 Notes to Financial Statements (continued) The holders of Preferred Shares have voting rights equal to the holders of Common Shares (one vote per share) and will vote together with holders of Common Shares (one vote per share) as a single class. However, holders of Preferred Shares, voting as a separate class, are also entitled to elect two Directors for the Fund. In addition, the 1940 Act requires that along with approval by shareholders that might otherwise be required, the approval of the holders of a majority of any outstanding Preferred Shares, voting separately as a class would be required to (a) adopt any plan of reorganization that would adversely affect the Preferred Shares, (b) change the Fund's subclassification as a closed-end investment company or change its fundamental investment restrictions or (c) change its business so as to cease to be an investment company. The yields in effect at October 31, 2008 were as follows: Series A, 3.488%; Series B, 2.988%; Series C, 2.988%; and Series D, 4.105%. Dividends on seven-day Preferred Shares are cumulative at a rate which is reset every seven days based on the results of an auction. Dividends on 28-day Preferred Shares are cumulative at a rate which is reset every 28 days based on the results of an auction. If the Preferred Shares fails to clear the auction on an auction date, the Fund is required to pay the maximum applicable rate on the Preferred Shares to holders of such shares for each successive dividend period until such time as the shares are successfully auctioned. The maximum applicable rate on the Preferred Shares, for Series A, B and C, is the higher of 110% of the AA commercial paper rate or 110% of 90% of the Kenny S&P 30-day High Grade Index rate divided by 1.00 minus the marginal tax rate and for Series D is the higher of 110% plus or times the Telerate/BBA LIBOR or 110% of 90% of the Kenny S&P 30-day High Grade Index rate divided by 1.00 minus the marginal tax rate. During the year ended October 31, 2008, the Preferred Shares of the Fund were successfully auctioned at each auction date until February 13, 2008. The low, high and average dividend rates on the Preferred Shares for the Fund for the year ended October 31, 2008 were as follows: - -------------------------------------------------------------------------------- Series Low High Average - -------------------------------------------------------------------------------- A ........................................... 2.535% 12.565% 4.081% B ........................................... 2.579% 8.651% 3.683% C ........................................... 2.000% 12.565% 3.706% D ........................................... 3.090% 10.377% 4.277% - -------------------------------------------------------------------------------- Since February 13, 2008, the Preferred Shares of the Fund failed to clear any of their auctions. As a result, the Preferred Shares dividend rates were reset to the maximum applicable rate, which ranged from 2.480% to 12.565%. A failed auction is not an event of default for the Fund but it has a negative impact on the liquidity of Preferred Shares. A failed auction occurs when there are more sellers of a fund's auction rate preferred shares than buyers. It is impossible to predict how long this imbalance will last. A successful auction for the Fund's Preferred Shares may not occur for some time, if ever, and even if liquidity does resume, holders of the Preferred Shares may not have the ability to sell the Preferred Shares at their liquidation preference. The Fund may not declare dividends or make other distributions on Common Shares or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding Preferred Shares is less than 200%. The Fund pays commissions to certain broker-dealers at the end of each auction at an annual rate of 0.25%, calculated on the aggregate principal amount. For the year ended October 31, 2008, Merrill Lynch, Pierce, Fenner & Smith Incorporated, a wholly owned subsidiary of Merrill Lynch, earned commissions of $221,296. Between June 4, 2008 and June 17, 2008, the Fund announced the following redemptions of Preferred Shares at a price of $25,000 plus any accrued and unpaid dividends through the redemption date: - -------------------------------------------------------------------------------- Redemption Shares Aggregate Series Date Redeemed Principal - -------------------------------------------------------------------------------- A .................................. 7/03/08 249 $6,225,000 B .................................. 7/10/08 249 $6,225,000 C .................................. 6/26/08 249 $6,225,000 D .................................. 6/24/08 221 $5,525,000 - -------------------------------------------------------------------------------- The Fund financed the Preferred Share redemptions with cash received from TOB transactions. Preferred Shares issued and outstanding for the year ended October 31, 2007 remained constant. 5. Income Tax Information: Reclassifications: Accounting principles generally accepted in the United States of America require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or on net asset values per share. The following permanent differences as of October 31, 2008 attributable to amortization methods on fixed income securities and the expiration of capital loss carryforwards, were reclassified to the following accounts: - -------------------------------------------------------------------------------- Decrease paid-in-capital ....................................... $(7,499,156) Decrease undistributed net investment income ................... $ (31,449) Increase accumulated net realized loss ......................... $ 7,530,605 - -------------------------------------------------------------------------------- BLACKROCK MUNIVEST FUND II, INC. OCTOBER 31, 2008 17 Notes to Financial Statements (concluded) The tax character of distributions paid during the fiscal years ended October 31, 2008 and October 31, 2007 was as follows: - -------------------------------------------------------------------------------- 10/31/2008 10/31/2007 - -------------------------------------------------------------------------------- Distributions paid from: Tax-exempt income .............................. $23,845,376 $23,790,532 Ordinary income ................................ 77,411 -- -------------------------- Total distributions .............................. $23,922,787 $23,790,532 ========================== As of October 31, 2008, the components of accumulated losses on a tax basis were as follows: Undistributed tax-exempt income ............................... $ 1,365,666 Undistributed ordinary income ................................. 129,654 ------------ Total undistributed earnings .................................. 1,495,320 Capital loss carryforward ..................................... (7,838,255) Net unrealized losses ......................................... (49,058,038) ------------ Total accumulated net losses .................................. $(55,400,973) ============ * The difference between book-basis and tax-basis net unrealized losses is attributable primarily to the tax deferral of losses on wash sales, the tax deferral of losses on straddles, the difference between book and tax amortization methods for premiums and discounts on fixed income securities and the difference between the book and tax treatment of residual interests in tender option bond trusts. As of October 31, 2008, the Fund had a capital loss carryforward of $7,838,255 available to offset future realized capital gains which expires October 31, 2016. 6. Concentration Risk: The Fund's investments are concentrated in certain states, which may be affected by adverse financial, social, environmental, economic, regulatory and political factors. Many municipalities insure repayment of their bonds, which reduces the risk of loss due to issuer default. The market value of these bonds may fluctuate for other reasons, including market perception of the value of such insurance, and there is no guarantee that the issuer will meet its obligation. 7. Subsequent Events: The Fund paid a tax-exempt income dividend to Common Shareholders in the amount of $0.071 per share on December 1, 2008 to shareholders of record on November 14, 2008. The dividends declared on Preferred Shares for the period November 1, 2008 to November 30, 2008 were as follows: Series A, $81,852; Series B, $84,446; Series C, $55,283; and Series D, $75,299. On September 15, 2008, Bank of America Corporation announced that it has agreed to acquire Merrill Lynch, one of the principal owners of BlackRock, Inc. The purchase has been approved by the shareholders and directors of both companies and certain regulators. Subject to other regulatory approvals, the transaction is expected to close on or about December 31, 2008. In December 2008, commissions paid to broker-dealers on preferred shares that experience a failed auction were reduced to 0.15% on the aggregate principal amount. The Fund will continue to pay commissions of 0.25% on the aggregate principal amount of all shares that successfully clear their auctions. 18 BLACKROCK MUNIVEST FUND II, INC. OCTOBER 31, 2008 Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors of BlackRock MuniVest Fund II, Inc.: We have audited the accompanying statement of assets and liabilities of BlackRock MuniVest Fund II, Inc. (the "Fund"), including the schedule of investments, as of October 31, 2008, 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 its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures include confirmation of securities owned as of October 31, 2008, 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 BlackRock MuniVest Fund II, Inc. as of October 31, 2008, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. Deloitte & Touche LLP Princeton, New Jersey December 24, 2008 Important Tax Information (Unaudited) The following summarizes the taxable per share distributions paid by BlackRock MuniVest Fund II, Inc. during the taxable year ended October 31, 2008: - -------------------------------------------------------------------------------- Ordinary Payable Date Income - -------------------------------------------------------------------------------- Common Shareholders 12/31/2007 $0.002752 - -------------------------------------------------------------------------------- Preferred Shareholders: Series A 12/20/2007 $3.10 Series B 12/27/2007 $3.13 Series C 12/06/2007 $3.04 Series D 12/18/2007 $3.07 - -------------------------------------------------------------------------------- All of the other net investment income distributions paid by the Fund qualify as tax-exempt interest dividends for federal income tax purposes. BLACKROCK MUNIVEST FUND II, INC. OCTOBER 31, 2008 19 Disclosure of Investment Advisory Agreement and Subadvisory Agreement The Board of Directors (the "Board," the members of which are referred to as "Directors") of the BlackRock MuniVest Fund II, Inc. (the "Fund") met in April and May 2008 to consider approving the continuation of the Fund's investment advisory agreement (the "Advisory Agreement") with BlackRock Advisors, LLC (the "Advisor"), the Fund's investment advisor. The Board also considered the approval of the Fund's subadvisory agreement (the "Subadvisory Agreement" and, together with the Advisory Agreement, the "Agreements") between the Advisor and BlackRock Investment Management, LLC (the "Subadvisor"). The Advisor and the Subadvisor are collectively referred to herein as the "Advisors" and, together with BlackRock, Inc., "BlackRock." Activities and Composition of the Board The Board of the Fund consists of thirteen individuals, eleven of whom are not "interested persons" of the Fund as defined in the Investment Company Act of 1940 (the "1940 Act") (the "Independent Directors"). The Directors are responsible for the oversight of the operations of the Fund and perform the various duties imposed on the directors of investment companies by the 1940 Act. The Independent Directors have retained independent legal counsel to assist them in connection with their duties. The Chairman of the Board is an Independent Director. The Board has established four standing committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee and a Performance Oversight Committee. Advisory Agreement and Subadvisory Agreement Upon the consummation of the combination of BlackRock, Inc.'s investment management business with Merrill Lynch & Co., Inc.'s investment management business, including Merrill Lynch Investment Managers, L.P., and certain affiliates, the Fund entered into the Advisory Agreement and the Subadvisory Agreement, each with an initial two-year term. Consistent with the 1940 Act, after the Advisory Agreement's and Subadvisory Agreement's respective initial two-year term, the Board is required to consider the continuation of the Fund's Advisory Agreement and Subadvisory Agreement on an annual basis. In connection with this process, the Board assessed, among other things, the nature, scope and quality of the services provided to the Fund by the personnel of BlackRock and its affiliates, including investment advisory services, administrative services, secondary market support services, oversight of fund accounting and custody, and assistance in meeting legal and regulatory requirements. The Board also received and assessed information regarding the services provided to the Fund by certain unaffiliated service providers. Throughout the year, the Board also considered a range of information in connection with its oversight of the services provided by BlackRock and its affiliates. Among the matters the Board considered were: (a) investment performance for one-, three- and five-year periods, as applicable, against peer funds, as well as senior management and portfolio managers' analysis of the reasons for underperformance, if applicable; (b) fees, including advisory, administration and other fees paid to BlackRock and its affiliates by the Fund, as applicable; (c) Fund operating expenses paid to third parties; (d) the resources devoted to and compliance reports relating to the Fund's investment objective, policies and restrictions; (e) the Fund's compliance with its Code of Ethics and compliance policies and procedures; (f) the nature, cost and character of non-investment management services provided by BlackRock and its affiliates; (g) BlackRock's and other service providers' internal controls; (h) BlackRock's implementation of the proxy voting guidelines approved by the Board; (i) execution quality; (j) valuation and liquidity procedures; and (k) reviews of BlackRock's business, including BlackRock's response to the increasing scale of its business. Board Considerations in Approving the Advisory Agreement and Subadvisory Agreement To assist the Board in its evaluation of the Agreements, the Directors received information from BlackRock in advance of the April 22, 2008 meeting which detailed, among other things, the organization, business lines and capabilities of the Advisors, including: (a) the responsibilities of various departments and key personnel and biographical information relating to key personnel; (b) financial statements for BlackRock; (c) the advisory and/or administrative fees paid by the Fund to the Advisors, including comparisons, compiled by Lipper Inc. ("Lipper"), an independent third party, with the management fees, which include advisory and administration fees, of funds with similar investment objectives ("Peers"); (d) the profitability of BlackRock and certain industry profitability analyses for advisors to registered investment companies; (e) the expenses of BlackRock in providing various services; (f) non-investment advisory reimbursements, if applicable, and "fallout" benefits to BlackRock; (g) economies of scale, if any, generated through the Advisors' management of all of the BlackRock closed-end funds (the "Fund Complex"); (h) the expenses of the Fund, including comparisons of the Fund's expense ratios (both before and after any fee waivers) with the expense ratios of its Peers; (i) an internal comparison of management fees classified by Lipper, if applicable; and (j) the Fund's performance for the past one-, three- and five-year periods, as applicable, as well as the Fund's performance compared to its Peers. 20 BLACKROCK MUNIVEST FUND II, INC. OCTOBER 31, 2008 Disclosure of Investment Advisory Agreement and Subadvisory Agreement (continued) The Board also considered other matters it deemed important to the approval process, where applicable, such as payments made to BlackRock or its affiliates relating to the distribution of Fund shares, services related to the valuation and pricing of Fund portfolio holdings, and direct and indirect benefits to BlackRock and its affiliates from their relationship with the Fund. In addition to the foregoing materials, independent legal counsel to the Independent Directors provided a legal memorandum outlining, among other things, the duties of the Board under the 1940 Act, as well as the general principles of relevant law in reviewing and approving advisory contracts, the requirements of the 1940 Act in such matters, an advisor's fiduciary duty with respect to advisory agreements and compensation, and the standards used by courts in determining whether investment company boards of directors have fulfilled their duties and the factors to be considered by boards in voting on advisory agreements. The Independent Directors reviewed this information and discussed it with independent legal counsel prior to the meeting on April 22, 2008. At the Board meeting on April 22, 2008, BlackRock made a presentation to and responded to questions from the Board. Following the meeting on April 22, 2008, the Board presented BlackRock with questions and requests for additional information. BlackRock responded to these requests with additional written materials provided to the Directors prior to the meetings on May 29 and 30, 2008. At the Board meetings on May 29 and 30, 2008, BlackRock responded to further questions from the Board. In connection with BlackRock's presentations, the Board considered each Agreement and, in consultation with independent legal counsel, reviewed the factors set out in judicial decisions and Securities and Exchange Commission ("SEC") statements relating to the renewal of the Agreements. Matters Considered by the Board In connection with its deliberations with respect to the Agreements, the Board considered all factors it believed relevant with respect to the Fund, including the following: the nature, extent and quality of the services provided by the Advisors; the investment performance of the Fund; the costs of the services to be provided and profits to be realized by the Advisors and their affiliates from their relationship with the Fund; the extent to which economies of scale would be realized as the Fund Complex grows; and whether BlackRock realizes other benefits from its relationship with the Fund. A. Nature, Extent and Quality of the Services: In evaluating the nature, extent and quality of the Advisors' services, the Board reviewed information concerning the types of services that the Advisors provide and are expected to provide to the Fund, narrative and statistical information concerning the Fund's performance record and how such performance compares to the Fund's Peers, information describing BlackRock's organization and its various departments, the experience and responsibilities of key personnel and available resources. The Board noted the willingness of the personnel of BlackRock to engage in open, candid discussions with the Board. The Board further considered the quality of the Advisors' investment process in making portfolio management decisions. In addition to advisory services, the Directors considered the quality of the administrative and non-investment advisory services provided to the Fund. The Advisors and their affiliates provided the Fund with such administrative and other services, as applicable (in addition to any such services provided by others for the Fund), and officers and other personnel as are necessary for the operations of the Fund. In addition to investment management services, the Advisors and their affiliates provided the Fund with services such as: preparing shareholder reports and communications, including annual and semi-annual financial statements and the Fund's website; communications with analysts to support secondary market trading; assisting with daily accounting and pricing; preparing periodic filings with regulators and stock exchanges; overseeing and coordinating the activities of other service providers; administering and organizing Board meetings and preparing the Board materials for such meetings; providing legal and compliance support (such as helping to prepare proxy statements and responding to regulatory inquiries); and performing other Fund administrative tasks necessary for the operation of the Fund (such as tax reporting and fulfilling regulatory filing requirements). The Board considered the Advisors' policies and procedures for assuring compliance with applicable laws and regulations. B. The Investment Performance of the Fund and BlackRock: As previously noted, the Board received performance information regarding the Fund and its Peers. Among other things, the Board received materials reflecting the Fund's historic performance and the Fund's one-, three- and five-year total returns (as applicable) relative to its Peers (including the Peers' median performance). The Board was provided with a description of the methodology used by Lipper to select the Fund's Peers. The Board noted that it regularly reviews the performance of the Fund throughout the year. The Board reviewed a narrative and statistical analysis of the Lipper data that was prepared by BlackRock, which analyzed various factors that affect Lipper rankings. BLACKROCK MUNIVEST FUND II, INC. OCTOBER 31, 2008 21 Disclosure of Investment Advisory Agreement and Subadvisory Agreement (continued) The Board noted that in general the Fund performed better than its Peers in that the Fund's performance was at or above the median of its Peers in at least two of the one-, three- and five-year periods reported. C. Consideration of the Advisory Fees and the Cost of the Services and Profits to be Realized by BlackRock and its Affiliates from their Relationship with the Fund: In evaluating the management fees and expenses that a Fund is expected to bear, the Board considered the Fund's current management fee structure and the Fund's expense ratios in absolute terms as well as relative to the fees and expense ratios of its applicable Peers. The Board, among other things, reviewed comparisons of the Fund's gross management fees before and after any applicable reimbursements and fee waivers and total expense ratios before and after any applicable waivers with those of applicable Peers. The Board also reviewed a narrative analysis of the Peer rankings prepared by Lipper and summarized by BlackRock at the request of the Board. This summary placed the Peer rankings into context by analyzing various factors that affect these comparisons. The Board noted that the Fund paid contractual management fees lower than or equal to the median contractual fees paid by the Fund's Peers. This comparison was made without giving effect to any expense reimbursements or fee waivers. The Board also compared the management fees charged and services provided by the Advisors to closed-end funds in general versus other types of clients (such as open-end investment companies and separately managed institutional accounts) in similar investment categories. The Board noted certain differences in services provided and costs incurred by the Advisor with respect to closed-end funds compared to these other types of clients and the reasons for such differences. In connection with the Board's consideration of the fees and expense information, the Board reviewed the considerable investment management experience of the Advisors and considered the high level of investment management, administrative and other services provided by the Advisors. D. Profitability of BlackRock: The Board also considered BlackRock's profitability in conjunction with its review of fees. The Board reviewed BlackRock's profitability with respect to the Fund Complex and other fund complexes managed by the Advisors. In reviewing profitability, the Board recognized that one of the most difficult issues in determining profitability is establishing a method of allocating expenses. The Board also reviewed BlackRock's assumptions and methodology of allocating expenses, noting the inherent limitations in allocating costs among various advisory products. The Board also recognized that individual fund or product line profitability of other advisors is generally not publicly available. The Board recognized that profitability may be affected by numerous factors including, among other things, the types of funds managed, expense allocations and business mix, and therefore comparability of profitability is somewhat limited. Nevertheless, to the extent available, the Board considered BlackRock's operating margin compared to the operating margin estimated by BlackRock for a leading investment management firm whose operations consist primarily of advising closed-end funds. The comparison indicated that BlackRock's operating margin was approximately the same as the operating margin of such firm. In evaluating the reasonableness of the Advisors' compensation, the Board also considered any other revenues paid to the Advisors, including partial reimbursements paid to the Advisors for certain non-investment advisory services, if applicable. The Board noted that these payments were less than the Advisors' costs for providing these services. The Board also considered indirect benefits (such as soft dollar arrangements) that the Advisors and their affiliates are expected to receive which are attributable to their management of the Fund. E. Economies of Scale: In reviewing the Fund's fees and expenses, the Board examined the potential benefits of economies of scale, and whether any economies of scale should be reflected in the Fund's fee structure, for example through the use of breakpoints for the Fund or the Fund Complex. In this regard, the Board reviewed information provided by BlackRock, noting that most closed-end fund complexes do not have fund-level breakpoints because closed-end funds generally do not experience substantial growth after their initial public offering and each fund is managed independently consistent with its own investment objectives. The Board noted that only three closed-end funds in the Fund Complex have breakpoints in their fee structures. Information provided by Lipper also revealed that only one closed-end fund complex used a complex-level breakpoint structure. The Board found, based on its review of comparable funds, that the Fund's management fee is appropriate in light of the scale of the Fund. 22 BLACKROCK MUNIVEST FUND II, INC. OCTOBER 31, 2008 Disclosure of Investment Advisory Agreement and Subadvisory Agreement (concluded) Other Factors: In evaluating fees, the Board also considered indirect benefits or profits the Advisors or their affiliates may receive as a result of their relationships with the Fund ("fall-out benefits"). The Directors, including the Independent Directors, considered the intangible benefits that accrue to the Advisors and their affiliates by virtue of their relationships with the Fund, including potential benefits accruing to the Advisors and their affiliates as a result of participating in offerings of the Fund's shares, potentially stronger relationships with members of the broker-dealer community, increased name recognition of the Advisors and their affiliates, enhanced sales of other investment funds and products sponsored by the Advisors and their affiliates and increased assets under management which may increase the benefits realized by the Advisors from soft dollar arrangements with broker-dealers. The Board also considered the unquantifiable nature of these potential benefits. Conclusion with Respect to the Agreements In reviewing and approving the continuation of the Agreements, the Directors did not identify any single factor discussed above as all-important or controlling, but considered all factors together, and different Directors may have attributed different weights to the various factors considered. The Independent Directors were also assisted by the advice of independent legal counsel in making this determination. The Directors, including the Independent Directors, unanimously determined that each of the factors described above, in light of all the other factors and all of the facts and circumstances applicable to the Fund, was acceptable for the Fund and supported the Directors' conclusion that the terms of each Agreement were fair and reasonable, that the Fund's fees are reasonable in light of the services provided to the Fund and that each Agreement should be approved. BLACKROCK MUNIVEST FUND II, INC. OCTOBER 31, 2008 23 Automatic Dividend Reinvestment Plan How the Plan Works -- The Fund offers a Dividend Reinvestment Plan (the "Plan") under which income and capital gains dividends paid by the Fund are automatically reinvested in additional Common Shares of the Fund. The Plan is administered on behalf of the shareholders by BNY Mellon Shareowner Services (the "Plan Agent"). Under the Plan, whenever the Fund declares a dividend, participants in the Plan will receive the equivalent in Common Shares of the Fund. The Plan Agent will acquire the shares for the participant's account either (i) through receipt of additional unissued but authorized shares of the Fund ("newly issued shares") or (ii) by purchase of outstanding shares of Common Shares on the open market on the New York Stock Exchange or elsewhere. If, on the dividend payment date, the Fund's net asset value per share is equal to or less than the market price per share plus estimated brokerage commissions (a condition often referred to as a "market premium"), the Plan Agent will invest the dividend amount in newly issued shares. If the Fund's net asset value per share is greater than the market price per share (a condition often referred to as a "market discount"), the Plan Agent will invest the dividend amount by purchasing on the open market additional shares. If the Plan Agent is unable to invest the full dividend amount in open market purchases, or if the market discount shifts to a market premium during the purchase period, the Plan Agent will invest any uninvested portion in newly issued shares. The shares acquired are credited to each shareholder's account. The amount credited is determined by dividing the dollar amount of the dividend by either (i) when the shares are newly issued, the net asset value per share on the date the shares are issued or (ii) when shares are purchased in the open market, the average purchase price per share. Participation in the Plan -- Participation in the Plan is automatic, that is, a shareholder is automatically enrolled in the Plan when he or she purchases Common Shares of the Fund unless the shareholder specifically elects not to participate in the Plan. Shareholders who elect not to participate will receive all dividend distributions in cash. Shareholders who do not wish to participate in the Plan must advise the Plan Agent in writing (at the address set forth below) that they elect not to participate in the Plan. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by writing to the Plan Agent. Benefits of the Plan -- The Plan provides an easy, convenient way for shareholders to make additional, regular investments in the Fund. The Plan promotes a long-term strategy of investing at a lower cost. All shares acquired pursuant to the Plan receive voting rights. In addition, if the market price plus commissions of the Fund's shares is above the net asset value, participants in the Plan will receive shares of the Fund for less than they could otherwise purchase them and with a cash value greater than the value of any cash distribution they would have received. However, there may not be enough shares available in the market to make distributions in shares at prices below the net asset value. Also, since the Fund does not redeem shares, the price on resale may be more or less than the net asset value. Plan Fees -- There are no enrollment fees or brokerage fees for participating in the Plan. The Plan Agent's service fees for handling the reinvestment of distributions are paid for by the Fund. However, brokerage commissions may be incurred when the Fund purchases shares on the open market and shareholders will pay a pro rata share of any such commissions. Tax Implications -- The automatic reinvestment of dividends and distributions will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such dividends. Therefore, income and capital gains may still be realized even though shareholders do not receive cash. The value of shares acquired pursuant to the Plan will generally be excluded from gross income to the extent that the cash amount reinvested would be excluded from gross income. If, when the Fund's shares are trading at a market premium, the Fund issues shares pursuant to the Plan that have a greater fair market value than the amount of cash reinvested, it is possible that all or a portion of the discount from the market value (which may not exceed 5% of the fair market value of the Fund's shares) could be viewed as a taxable distribution. If the discount is viewed as a taxable distribution, it is also possible that the taxable character of this discount would be allocable to all the shareholders, including shareholders who do not participate in the Plan. Thus, shareholders who do not participate in the Plan might be required to report as ordinary income a portion of their distributions equal to their allocable share of the discount. Contact Information -- All correspondence concerning the Plan, including any questions about the Plan, should be directed to the Plan Agent at BNY Mellon Shareowner Services, P.O. Box 358035, Pittsburgh, PA 15252-8035, Telephone: (866) 216-0242. 24 BLACKROCK MUNIVEST FUND II, INC.

OCTOBER 31, 2008 29 Additional Information (continued) 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. Fund Certification The Fund is listed for trading on the New York Stock Exchange ("NYSE") and has filed with the NYSE its annual chief executive officer certification regarding compliance with the NYSE's listing standards.

OCTOBER 31, 2008 Additional Information (concluded) General Information The Fund does not make available copies of its Statements of Additional Information because the Fund's shares are not continuously offered, which means that the Statement of Additional Information of the Fund has not been updated after completion of the Fund's offering and the information contained in the Fund's Statement of Additional Information may have become outdated. During the period, there were no material changes in the Fund's investment objectives or policies or to the Fund's charters or by-laws that were not approved by the shareholders or in the principal risk factors associated with investment in the Fund. There have been no changes in the persons who are primarily responsible for the day-to-day management of the Fund's portfolios. The Fund will mail only one copy of shareholder documents, including annual and semi-annual reports and proxy statements, to shareholders with multiple accounts at the same address. This practice is commonly called "householding" and it is intended to reduce expenses and eliminate duplicate mailings of shareholder documents. Mailings of your shareholder documents may be householded indefinitely unless you instruct us otherwise. If you do not want the mailing of these documents to be combined with those for other members of your household, please contact the Fund at (800) 441-7762. Quarterly performance, semi-annual and annual reports and other information regarding the Fund may be found on BlackRock's website, which can be accessed at http://www.blackrock.com. This reference to BlackRock's website is intended to allow investors public access to information regarding the Fund and does not, and is not intended to, incorporate BlackRock's website into this report. Articles Supplementary Effective September 13, 2008, following approval by the Fund's Board and the applicable rating agencies, the Board amended the terms of the Fund's Preferred Shares in order to allow the Fund to enter into TOB transactions, the proceeds of which were used to redeem a portion of the Fund's Preferred Shares. Accordingly, the definition of Inverse Floaters was amended to incorporate the Fund's permissible ratio of floating rate instruments into inverse floating rate instruments. Additionally, conforming changes and certain formula modifications concerning inverse floaters were made to the definitions of Moody's Discount Factor and S&P Discount Factor, as applicable, to integrate the Fund's investments in TOBs into applicable calculations.

Item 3 - Audit Committee Financial Expert - The registrant's board of directors or trustees, as applicable (the "board of directors") has determined that (i) the registrant has the following audit committee financial experts serving on its audit committee and (ii) each audit committee financial expert is independent: Kent Dixon Frank J. Fabozzi James T. Flynn W. Carl Kester Karen P. Robards Robert S. Salomon, Jr. The registrant's board of directors has determined that W. Carl Kester and Karen P. Robards qualify as financial experts pursuant to Item 3(c)(4) of Form N-CSR. Prof. Kester has a thorough understanding of generally accepted accounting principles, financial statements and internal control over financial reporting as well as audit committee functions. Prof. Kester has been involved in providing valuation and other financial consulting services to corporate clients since 1978. Prof. Kester's financial consulting services present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the registrant's financial statements. Ms. Robards has a thorough understanding of generally accepted accounting principles, financial statements and internal control over financial reporting as well as audit committee functions. Ms. Robards has been President of Robards & Company, a financial advisory firm, since 1987. Ms. Robards was formerly an investment banker for more than 10 years where she was responsible for evaluating and assessing the performance of companies based on their financial results. Ms. Robards has over 30 years of experience analyzing financial statements. She also is a member of the audit committee of one publicly held company and a non-profit organization.

The designation or identification as an audit committee financial expert does not impose on such person any duties, obligations, or liabilities greater than the duties, obligations, and liabilities imposed on such person as a member of the audit committee and board of directors in the absence of such designation or identification.

(e)(1) Audit Committee Pre-Approval Policies and Procedures: The registrant's audit committee (the "Committee") has adopted policies and procedures with regard to the pre-approval of services. Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the registrant's affiliated service providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are a) consistent with the SEC's auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). The term of any general pre-approval is 12 months from the date of the pre-approval, unless the Committee provides for a different period. Tax or other non-audit services provided to the registrant which have a direct impact on the operation or financial reporting of the registrant will only be deemed pre-approved provided that any individual project does not exceed $10,000 attributable to the registrant or $50,000 for all of the registrants the Committee oversees. For this purpose, multiple projects will be aggregated to determine if they exceed the previously mentioned cost levels. Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting. At this meeting, an analysis of such services is presented to the Committee for ratification. The Committee may delegate to one or more of its members the authority to approve the provision of and fees for any specific engagement of permitted non-audit services, including services exceeding pre-approved cost levels. (e)(2) None of the services described in each of Items 4(b) through (d) were approved by the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Regulation S-X Rule 2-01(c)(7)(ii) - $287,500, 0% Item 5 - Audit Committee of Listed Registrants - The following individuals are members of the registrant's separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934 (15 U.S.C. 78c(a)(58)(A)): Kent Dixon Frank J.

(b) Not Applicable due to no such divestments during the semi-annual period covered since the previous Form N-CSR filing. Item 7 - Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies - The board of directors has delegated the voting of proxies for the Fund securities to the Fund's investment advisor ("Investment Adviser") pursuant to the Investment Adviser's proxy voting guidelines. Under these guidelines, the Investment Adviser will vote proxies related to Fund securities in the best interests of the Fund and its stockholders. From time to time, a vote may present a conflict between the interests of the Fund's stockholders, on the one hand, and those of the Investment Adviser, or any affiliated person of the Fund or the Investment Adviser, on the other. In such event, provided that the Investment Adviser's Equity Investment Policy Oversight Committee, or a sub-committee thereof (the "Oversight Committee") is aware of the real or potential conflict or material non-routine matter and if the Oversight Committee does not reasonably believe it is able to follow its general voting guidelines (or if the particular proxy matter is not addressed in the guidelines) and vote impartially, the Oversight Committee may retain an independent fiduciary to advise the Oversight Committee on how to vote or to cast votes on behalf of the Investment Adviser's clients. If the Investment Adviser determines not to retain an independent fiduciary, or does not desire to follow the advice of such independent fiduciary, the Oversight Committee shall determine how to vote the proxy after consulting with the Investment Adviser's Portfolio Management Group and/or the Investment Adviser's Legal and Compliance Department and concluding that the vote cast is in its client's best interest notwithstanding the conflict. A copy of the Fund's Proxy Voting Policy and Procedures are attached as Exhibit 99.PROXYPOL. Information on how the Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available without charge, (i) at www.blackrock.com and (ii) on the SEC's website at http://www.sec.gov. Item 8 - Portfolio Managers of Closed-End Management Investment Companies - as of October 31, 2008. (a)(1) BlackRock MuniVest Fund II, Inc. is managed by a team of investment professionals comprised of Theodore R. Jaeckel, Jr., CFA and Walter O'Connor. Each is a member of BlackRock's municipal tax-exempt management group. Each is jointly responsible for the day-to-day management of the Fund's portfolio, which includes setting the Fund's overall investment strategy, overseeing the management of the Fund and/or selection of its investments. Messrs. Jaeckel and O'Connor have been members of the Fund's portfolio management team since 2006. Mr. Jaeckel joined BlackRock in 2006. Prior to joining BlackRock, he was a Managing Director (Municipal Tax-Exempt Fund Management) of Merrill Lynch Investment Managers, L.P. ("MLIM") from 2005 to 2006 and a Director of MLIM from 1997 to 2005. He has been a portfolio manager with BlackRock or MLIM since 1991. Mr. O'Connor joined BlackRock in 2006.

BlackRock has adopted policies and procedures that address the allocation of investment opportunities, execution of portfolio transactions, personal trading by employees and other potential conflicts of interest that are designed to ensure that all client accounts are treated equitably over time. Nevertheless, BlackRock furnishes investment management and advisory services to numerous clients in addition to the Fund, and BlackRock may, consistent with applicable law, make investment recommendations to other clients or accounts (including accounts which are hedge funds or have performance or higher fees paid to BlackRock, or in which portfolio managers have a personal interest in the receipt of such fees), which may be the same as or different from those made for the Fund. In addition, BlackRock, its affiliates and any officer, director, stockholder or employee may or may not have an interest in the securities whose purchase and sale BlackRock recommends to the Fund. BlackRock, or any of its affiliates, or any officer, director, stockholder, employee or any member of their families may take different actions than those recommended to the Fund by BlackRock with respect to the same securities. Moreover, BlackRock may refrain from rendering any advice or services concerning securities of companies of which any of BlackRock's (or its affiliates') officers, directors or employees are directors or officers, or companies as to which BlackRock or any of its affiliates or the officers, directors or employees of any of them has any substantial economic interest or possesses material non-public information. Each portfolio manager also may manage accounts whose investment strategies may at times be opposed to the strategy utilized for a fund. In this regard, it should be noted that a portfolio manager may currently manage certain accounts that are subject to performance fees. In addition, a portfolio manager may assist in managing certain hedge funds and may be entitled to receive a portion of any incentive fees earned on such funds and a portion of such incentive fees may be voluntarily or involuntarily deferred. Additional portfolio managers may in the future manage other such accounts or funds and may be entitled to receive incentive fees. As a fiduciary, BlackRock owes a duty of loyalty to its clients and must treat each client fairly. When BlackRock purchases or sells securities for more than one account, the trades must be allocated in a manner consistent with its fiduciary duties. BlackRock attempts to allocate investments in a fair and equitable manner among client accounts, with no account receiving preferential treatment. To this end, BlackRock has adopted a policy that is intended to ensure that investment opportunities are allocated fairly and equitably among client accounts over time. This policy also seeks to achieve reasonable efficiency in client transactions and provide BlackRock with sufficient flexibility to allocate investments in a manner that is consistent with the particular investment discipline and client base. (a)(3) As of October 31, 2008: Portfolio Manager Compensation Overview BlackRock's financial arrangements with its portfolio managers, its competitive compensation and its career path emphasis at all levels reflect the value senior management places on key resources. Compensation may include a variety of components and may vary from year to year based on a number of factors. The principal components of compensation include a base salary, a performance-based discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by BlackRock such as its Long-Term Retention and Incentive Plan. Base compensation. Generally, portfolio managers receive base compensation based on their seniority and/or their position with the firm. Senior portfolio managers who perform additional management functions within the portfolio management group or within BlackRock may receive additional compensation for serving in these other capacities. Discretionary Incentive Compensation Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager's group within BlackRock, the investment performance, including risk-adjusted returns, of the firm's assets under management or supervision by that portfolio manager relative to predetermined benchmarks, and the individual's seniority, role within the portfolio management team, teamwork and contribution to the overall performance of these portfolios and BlackRock. In most cases, including for the portfolio managers of the Fund, these benchmarks are the same as the benchmark or benchmarks against which the performance of the Fund or other accounts managed by the portfolio managers are measured. BlackRock's Chief Investment Officers determine the benchmarks against which the performance of funds and other accounts managed by each portfolio manager is compared and the period of time over which performance is evaluated. With respect to the portfolio managers, such benchmarks for the Fund include a combination of market-based indices (e.g., Barclays Capital Municipal Bond Index), certain customized indices and certain fund industry peer groups. BlackRock's Chief Investment Officers make a subjective determination with respect to the portfolio managers' compensation based on the performance of the funds and other accounts managed by each portfolio manager relative to the various benchmarks noted above. Performance is measured on both a pre-tax and after-tax basis over various time periods including 1, 3, 5 and 10-year periods, as applicable. Distribution of Discretionary Incentive Compensation Discretionary incentive compensation is distributed to portfolio managers in a combination of cash and BlackRock, Inc. restricted stock units which vest ratably over a number of years. The BlackRock, Inc. restricted stock units, if properly vested, will be settled in BlackRock, Inc. common stock. Typically, the cash bonus, when combined with base salary, represents more than 60% of total compensation for the portfolio managers. Paying a portion of annual bonuses in stock puts compensation earned by a portfolio manager for a given year "at risk" based on BlackRock's ability to sustain and improve its performance over future periods. Long-Term Retention and Incentive Plan ("LTIP") -- The LTIP is a long-term incentive plan that seeks to reward certain key employees. Beginning in 2006, awards are granted under the LTIP in the form of BlackRock, Inc. restricted stock units that, if properly vested and subject to the attainment of certain performance goals, will be settled in BlackRock, Inc. common stock. Messrs. Jaeckel and O'Connor have each received awards under the LTIP. Deferred Compensation Program -- A portion of the compensation paid to eligible BlackRock employees may be voluntarily deferred into an account that tracks the performance of certain of the firm's investment products. Each participant in the deferred compensation program is permitted to allocate his deferred amounts among the various investment options. Messrs. Jaeckel and O'Connor have each participated in the deferred compensation program. Other compensation benefits. In addition to base compensation and discretionary incentive compensation, portfolio managers may be eligible to receive or participate in one or more of the following: Incentive Savings Plans -- BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement Savings Plan (RSP), and the BlackRock Employee Stock Purchase Plan (ESPP). The employer contribution components of the RSP include a company match equal to 50% of the first 6% of eligible pay contributed to the plan capped at $4,000 per year, and a company retirement contribution equal to 3% of eligible compensation, plus an additional contribution of 2% for any year in which BlackRock has positive net operating income. The RSP offers a range of investment options, including registered investment companies managed by the firm. BlackRock contributions follow the investment direction set by participants for their own contributions or, absent employee investment direction, are invested into a balanced portfolio. The ESPP allows for investment in BlackRock common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares or a dollar value of $25,000. Each portfolio manager is eligible to participate in these plans.
