These factors were offset by the positive impact from robust export activity, strength in the non-financial corporate sector and monetary and fiscal stimuli. Amid the market turbulence, the Federal Reserve Board (the "Fed") initiated a series of moves to restore liquidity and bolster financial market stability. Since September 2007, the central bank slashed the target federal funds rate 325 basis points (3.25%), bringing the rate to 2.0% as of period-end. Also of significance were its other policy decisions, which included extending use of the discount window to broker-dealers and investment banks and backstopping the rescue of ill-fated Bear Stearns. Notably, on April 30, the Fed dropped previous references to downside growth risks and added more emphasis on inflationary pressures, indicating the central bankers have likely concluded the current cycle of monetary easing. Nevertheless, the Fed's response to the financial crisis helped to ease credit turmoil and investor anxiety. Since hitting a low point on March 17, following the collapse of Bear Stearns, stocks appreciated 10% (through May 30). Most international markets, which had outperformed U.S. stocks for some time, saw a reversal in that trend, as the troubled credit situation and downward pressures on growth fanned recession fears. In fixed income markets, Treasury securities rallied (yields fell as prices correspondingly rose), as a broad "flight-to-quality" theme persisted. The yield on 10-year Treasury issues, which touched 5.30% in June 2007 (its highest level in five years), fell to a low of 3.34% in March 2008 before rising to 4.06% by May 31 as investors grew more risk tolerant and shifted out of Treasury issues in favor of stocks and other high-quality fixed income sectors. Tax-exempt issues underperformed throughout most of the reporting period, pressured by problems among municipal bond insurers and the freeze in the market for auction rate securities. However, the final two months saw a firmer tone in the municipal market, as investors took advantage of unusually high yields. On the whole, results for the major benchmark indexes generally reflected heightened investor risk aversion: Total Returns as of May 31, 2008 6-month 12-month ================================================================================================================ U.S. equities (S&P 500 Index) (4.47%) (6.70%) - ---------------------------------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) (1.87) (10.53) - ---------------------------------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) (5.21) (2.53) - ---------------------------------------------------------------------------------------------------------------- Fixed income (Lehman Brothers U.S. Aggregate Index) 1.49 6.89 - ---------------------------------------------------------------------------------------------------------------- Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) 1.44 3.87 - ---------------------------------------------------------------------------------------------------------------- High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Capped Index) 1.81 (1.08) - ---------------------------------------------------------------------------------------------------------------- Past performance is no guarantee of future results.

Fund results for the 12-month period lagged the broad-market Lehman Brothers Municipal Bond Index and the Lipper Florida Municipal Debt Funds category average. Unlike the Lehman Index, which measures the performance of municipal bonds nationally, the Lipper category consists of funds that limit their investment to securities exempt from taxation in Florida. What factors influenced performance? o U.S. Treasury yields generally moved lower (while prices correspondingly rose) during the year in response to weaker domestic economic growth and declining equity valuations. The Federal Reserve Board cut short-term interest rates seven times from 5.25% to 2.0%. o The municipal market underperformed U.S. Treasury issues, as credit downgrades of the monoline insurers and disruption of the auction rate securities market weighed heavily on the sector. Long-term municipal bond yields were acutely affected. New issuance for the period was relatively strong, despite a 12% decline in the past six months. More recently, the pace has increased, alongside improved investor demand. o The Fund's relative performance was adversely affected by its longer-maturity municipal bond holdings, which performed poorly as interest rates rose during the period. Credit spreads widened to levels not seen in several years. Specific sectors that detracted from performance included uninsured healthcare, land-secured bonds and corporate-issued municipal securities. Additionally, bonds insured by monoline insurers FGIC, XLCA, AMBAC, MBIA and CIFG underperformed issues insured by FSA and Assured Guaranty. o On the positive side, the Fund's holdings in prerefunded bonds enhanced results, as subprime mortgage problems and the failure of the auction rate securities market spurred a flight to quality, benefiting the short end of the municipal market. Describe recent portfolio activity. o During the reporting period, we took advantage of the increase in volatility in the market to participate in some tax-loss swaps. In effect, we were willing to take losses on the sale of selected bonds in order to offset present and future capital gain tax liabilities for shareholders. This also meant we were swapping into bonds with more attractive yields. We found some compelling opportunities in the new-issue market, as well, and acquired bonds with coupons ranging from 5.25% to 6.00%. Describe Fund positioning at period-end. o The Fund maintained a fully invested portfolio throughout and ended the reporting period with a neutral duration relative to the Lipper peer group. 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. 4 ANNUAL REPORT MAY 31, 2008 BlackRock Florida Municipal Bond Fund Total Return Based on a $10,000 Investment A line graph depicting the growth of an investment in the Fund's Institutional and Investor A Shares compared to growth of an investment in the Lehman Brothers Municipal Bond Index.

ANNUAL REPORT MAY 31, 2008 5 Fund Summary as of May 31, 2008 BlackRock New Jersey Municipal Bond Fund Portfolio Management Commentary How did the Fund perform? o The Fund recently changed its fiscal year end to May 31. The Fund underperformed the broad-market Lehman Brothers Municipal Bond Index and the Lipper New Jersey Municipal Debt Funds category average for the 12-month period. Unlike the Lehman Index, which measures the performance of municipal bonds nationally, the Lipper category consists of funds that limit their investment to securities exempt from taxation in New Jersey. What factors influenced performance? o U.S. Treasury yields generally moved lower (while prices correspondingly rose) during the year in response to weaker domestic economic growth and declining equity valuations. The Federal Reserve Board cut short-term interest rates seven times from 5.25% to 2.0%. o The municipal market underperformed U.S. Treasury issues, as credit downgrades of the monoline insurers and disruption of the auction rate securities market weighed heavily on the sector. Long-term municipal bond yields were acutely affected. New issuance for the period was relatively strong, despite a 12% decline in the past six months. More recently, the pace has increased, alongside improved investor demand. o The Fund's exposure to higher-yielding (primarily, longer-dated) holdings detracted from relative performance, as these issues underperformed amid substantial widening in credit spreads. The Fund's higher-quality insured holdings -- which would typically benefit from a "flight-to-quality" environment -- also came under pressure amid the turmoil in the monoline insurance industry. o On the positive side, an above-average yield helped mitigate the negative effects of the unprecedented market volatility and contributed positively to the Fund's total return. Additionally, we maintained a broadly diversified portfolio with credits and coupon structures that are attractive to the retail buyer. This proved advantageous, as strong retail demand allowed us to sell select holdings at above-market prices. Describe recent portfolio activity. o Fund activity was limited during the reporting period, as a scarce supply of new issues limited management's opportunities to restructure the portfolio. Trading activity consisted primarily of opportunistically feeding retail investor interest and adding higher-yielding securities in order to increase the distribution rate of the Fund. In general, we focused on purchasing bonds with higher credit ratings, while also looking for select opportunities to add lower-quality investment-grade bonds at attractively wide credit spreads. Describe Fund positioning at period-end. o The Fund ended the period with a slightly longer duration relative to its Lipper peer group, a posture we believe will benefit from a recovering municipal market, steadily slowing economy and declining yields.

ANNUAL REPORT MAY 31, 2008 7 Fund Summary as of May 31, 2008 BlackRock Pennsylvania Municipal Bond Fund Portfolio Management Commentary How did the Fund perform? o The Fund recently changed its fiscal year end to May 31. Fund performance lagged the broad-market Lehman Brothers Municipal Bond Index for the 12-month period. o The Fund's Institutional, Service, Investor A and Investor A1 shares outperformed the Lipper Pennsylvania Municipal Debt Funds category average for the 12-month period, while its Investor B, Investor B1, Investor C and Investor C1 shares underperformed. Unlike the Lehman Index, which measures the performance of municipal bonds nationally, the Lipper category consists of funds that limit their investment to securities exempt from taxation in Pennsylvania. What factors influenced performance? o U.S. Treasury yields generally moved lower (while prices correspondingly rose) during the year in response to weaker domestic economic growth and declining equity valuations. The Federal Reserve Board cut short-term interest rates seven times from 5.25% to 2.0%. o The municipal market underperformed U.S. Treasury issues, as credit downgrades of the monoline insurers and disruption of the auction rate securities market weighed heavily on the sector. Long-term municipal bond yields were acutely affected. New issuance for the period was relatively strong, despite a 12% decline in the past six months. More recently, the pace has increased, alongside improved investor demand. o The Fund's slightly longer duration relative to its Lipper peer group detracted from comparative results, as long-term municipal interest rates rose during the reporting period. o On the positive side, the Fund's performance versus its peers benefited from a relatively higher yield. The Fund's higher yield was attributable to its positions in derivatives (securities whose prices are dependent upon or derived from one or more underlying assets) and its holdings in bonds with higher coupon rates. Describe recent portfolio activity. o In an effort to take advantage of an improving municipal market, we attempted to increase the Fund's duration to slightly above the level of the Lipper peer group. A lack of new issuance in Pennsylvania did present some challenges as it limited the supply of appropriate securities that could have been added to the Fund. o Nevertheless, we were able to sell certain shorter-maturity bonds, while purchasing longer maturities that offered attractive long-term yields. In addition, we engaged in some tax-loss swaps. In effect, we were willing to take losses on the sale of selected bonds in order to offset present and future capital gains, which are taxable to our shareholders. This also meant that we were swapping into bonds with more attractive yields. Describe Fund positioning at period-end. o The Fund ended the reporting period with a slightly longer duration versus its Lipper peer group.

Current performance may be lower or higher than the performance data quoted. Refer to www.blackrock.com/funds to obtain performance data current to the most recent month-end. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the performance tables on pages 5, 7 and 9 assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the payable date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original costs. Dividends paid to each class of shares will vary because of the different levels of service, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders. For BlackRock New Jersey Municipal Bond Fund and BlackRock Pennsylvania Municipal Bond Fund, BlackRock Advisors, LLC, the Funds' investment manager, agreed to reimburse a portion of their fee. Without such reimbursement, the Funds' performance would have been lower. Disclosure of Expenses Shareholders of each Fund may incur the following charges: (a) expenses related to transactions, including sales charges, redemption fees and exchange fees; and (b) operating expenses, including advisory fees, distribution fees including 12b-1 fees, and other Fund expenses. The expense examples on pages 12 and 13 (which are based on a hypothetical investment of $1,000 invested on December 1, 2007 and held through May 31, 2008) are intended to assist shareholders both in calculating expenses based on an investment in each Fund and in comparing these expenses with similar costs of investing in other mutual funds. The tables provide information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number corresponding to their share class under the heading entitled "Expenses Paid During the Period." The tables also provide information about hypothetical account values and hypothetical expenses based on each Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in these Funds and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds' shareholder reports. The expenses shown in the tables are intended to highlight shareholders' ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees or exchange fees.

See Notes to Financial Statements. 48 ANNUAL REPORT MAY 31, 2008 Notes to Financial Statements 1. Significant Accounting Policies: BlackRock Florida Municipal Bond Fund, BlackRock New Jersey Municipal Bond Fund and BlackRock Pennsylvania Municipal Bond Fund (the "Funds" or each a "Fund"), each a series of BlackRock Multi-State Municipal Series Trust (the "Trust"), are registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as non-diversified, open-end management investment companies. The Funds' 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 Funds recently changed their fiscal year end to May 31. Each Fund offers multiple classes of shares. Institutional and Service Shares are sold only to certain eligible investors. Investor A Shares are generally sold with a front-end sales charge. Investor A1, Investor B, Investor B1 and Investor C1 Shares are not generally available except for dividend and capital gains investment. Shares of Investor B, Investor B1, Investor C and Investor C1 may be subject to a contingent deferred sales charge. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Service, Investor A, Investor A1, Investor B, Investor B1, Investor C and Investor C1 Shares bear certain expenses related to the shareholder servicing of such shares, and Investor B, Investor B1, Investor C and Investor C1 Shares also bear certain expenses related to the distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its shareholder servicing and distribution expenditures (except that Investor B and Investor B1 shareholders may vote on material changes to the Investor A and Investor A1 distribution plans). The following is a summary of significant accounting policies followed by the Funds: 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 Trust's Board of Trustees (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 bond dealers, pricing matrixes, market transactions in comparable investments and various relationships between investments. Swap agreements are valued by quoted fair values received daily by the Trust's pricing service or through brokers. Financial futures contracts are traded on exchanges and are valued at their last sale price. 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 the sub-advisor seeks to determine the price that each 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 Funds may engage in various portfolio investment strategies to increase the return of the Fund and to hedge, or protect, their 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 contract. o Financial futures contracts -- The Funds may purchase or sell financial futures contracts and options on such financial futures contracts. Financial 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 Funds deposit, and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Funds agree 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 Funds as unrealized gains or losses. When the contract is closed, the Funds record 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 Forward interest rate swaps -- The Funds 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. These periodic payments received or made by the Fund are recorded in the accompanying Statements of Operations as realized gains or losses, respectively. Gains or losses are also realized upon termination of the swap agreements. Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). When the swap is terminated, the Funds will record a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Funds' basis in the contract, if any. The Funds generally intend to close each forward interest rate swap before the accrual 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 Funds 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 Funds 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. ANNUAL REPORT MAY 31, 2008 49 Notes to Financial Statements (continued) Since the value of securities purchased may fluctuate prior to settlement, the Funds 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. Upon making a commitment to purchase a security on a when-issued basis, the Funds will hold liquid assets worth at least the equivalent of the amount due. Municipal Bonds Transferred to Tender Option Bond Trusts: The Funds leverage their 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 Funds have 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 Funds. The TOB Residuals held by a 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. Each 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 Funds' Schedule of Investments and the proceeds from the transaction are reported as a liability of the Fund. Similarly, proceeds from residual certificates issued to affiliates, if any, from the transaction are included in liability for trust certificates. Interest income from the underlying security is recorded by the Funds 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 Funds. 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 May 31, 2008, the aggregate value of the underlying municipal securities transferred to TOBs, the related liability for trust certificates and the range of interest rates on the trust certificates were as follows: - -------------------------------------------------------------------------------- Underlying Municipal Liability Bonds for Transferred Trust Range of to TOBs Certificates Interest Rates - -------------------------------------------------------------------------------- BlackRock Florida Municipal Bond Fund ...................... $20,811,469 $9,807,764 1.67% - 3.058% BlackRock New Jersey Municipal Bond Fund ...................... $ 6,460,847 $3,875,000 1.67% - 2.291% BlackRock Pennsylvania Municipal Bond Fund ...................... $15,949,616 $8,300,000 2.84% - 3.147% - -------------------------------------------------------------------------------- Financial transactions executed through TOBs generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment, 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 Funds' investment in TOBs likely will adversely affect the Funds' net investment income and dividends to shareholders. Fluctuations in the market value of municipal securities deposited into the TOB may adversely affect the Funds' net asset values per share. Zero-Coupon Bonds: The Funds may invest in zero-coupon bonds, which are normally issued at a significant discount from face value and do not provide for periodic interest payments. Zero-coupon bonds may experience greater volatility in market value than similar maturity debt obligations which provide for regular interest payments. Segregation: In cases in which the 1940 Act and the interpretive positions of the Securities and Exchange Commission ("SEC") require that each Fund segregate assets in connection with certain investments (e.g., when-issued securities or swaps), each Fund will, consistent with certain interpretive letters issued by the SEC, designate on its books and records cash or other liquid debt securities having a market value at least equal to the amount that would otherwise be required to be physically segregated. 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 dates. Interest income is recognized on the accrual basis. The Funds amortize all premiums and discounts on debt securities. Income and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. Dividends and Distributions: Dividends from net investment income are declared daily and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. Income Taxes: It is the Funds' policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of their taxable income to their shareholders. Therefore, no federal income tax provision is required. Effective January 31, 2008, the Funds 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 Funds, and has determined that the adoption of FIN 48 does not have a material impact on the Funds' financial statements. 50 ANNUAL REPORT MAY 31, 2008 Notes to Financial Statements (continued) The Funds file U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Funds' U.S. federal tax returns remains open for the years ended July 31, 2005 through July 31, 2007. The statutes of limitations on the Funds' 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 Funds' financial statement disclosures, if any, is currently being assessed. In addition, in February 2007, Statement of Financial Accounting Standards No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities" ("FAS 159"), was issued and is effective for fiscal years beginning after November 15, 2007. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. FAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. The impact on the Funds' financial statement 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 and is effective effective for fiscal years beginning after November 15, 2008.

Short-Term Borrowings: The Trust, on behalf of the Funds, along with certain other funds managed by the Advisor and its affiliates, is party to a $500,000,000 credit agreement with a group of lenders. The Funds may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Funds may borrow up to the maximum amount allowable under the Funds' current Prospectuses and Statements of Additional Information, subject to various other legal, regulatory or contractual limits. On November 21, 2007, the credit agreement was renewed for one year under substantially the same terms. The Funds pay a commitment fee of 0.06% per annum based on the Funds' pro rata share of the unused portion of the credit agreement, which is included in miscellaneous in the Statements of Operations. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each fund's election, the federal funds rate plus 0.35% or a base rate as defined in the credit agreement. The Funds did not borrow under the credit agreement during the period August 1, 2007 to May 31, 2008. 6. Income Tax Information: Reclassifications: BlackRock Florida Municipal Bond Fund 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. Accordingly, during the current year, $2,653,250 has been reclassified between paid-in capital in excess of par and accumulated net realized loss as a result of a permanent difference attributable to the expiration of capital loss carryforwards. These reclassifications have no effect on net assets or net asset values per share.

Concentration Risk: Each 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 and there is no assurance that the insurer will meet its obligation. ANNUAL REPORT MAY 31, 2008 63 Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Trustees of BlackRock Multi-State Municipal Series Trust: We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of BlackRock Florida Municipal Bond Fund, BlackRock New Jersey Municipal Bond Fund and BlackRock Pennsylvania Municipal Bond Fund, three of the portfolios constituting BlackRock Multi-State Municipal Series Trust (the "Trust"), as of May 31, 2008, and the related statements of operations for the period August 1, 2007 to May 31, 2008 and for the year ended July 31, 2007, the statements of changes in net assets for the period August 1, 2007 to May 31, 2008 and for each of the two years in the period ended July 31, 2007, and the financial highlights for each of the respective periods presented. These financial statements and financial highlights are the responsibility of the Trust'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 Trust 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 Trust'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.

(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.
