------------------------------------------------------------------------------- THE BLACKROCK INSURED MUNICIPAL 2008 TERM TRUST INC. ANNUAL REPORT TO SHAREHOLDERS REPORT OF INVESTMENT ADVISOR ------------------------------------------------------------------------------- January 31, 2001 Dear Shareholder: The continued trend of economic growth boosted by strong consumer confidence, a tight labor market and inflation concerns caused the Federal Reserve to aggressively tighten during the first five months of the year. As a result, the Fed raised the discount rate to 6.50% during the year in an attempt to achieve its objective of engineering a "soft landing" for the explosive U.S. economy. The third quarter of 2000 saw a sharp decline in market expectations for further Fed tightenings amidst evidence of significant deceleration in growth, peaking inflation pressures and a sharp reversal in the stock market wealth effect globally. During the fourth quarter, investor hopes for a "soft landing" quickly turned into fears of a recession as the U.S. economy rapidly deteriorated. The effects of tighter monetary and fiscal conditions, along with higher energy prices, combined to pull down domestic growth rates. As market expectations transitioned from Fed tightening to a significant Fed easing, high quality fixed-income assets, led by the Treasury market, produced strong double-digit returns. The Federal Reserve has expressed great concern over the economy's quick downturn. After removing their tightening bias at their December meeting, the FOMC acted with an aggressive 50 basis point intra-meeting reduction of the Fed Funds rate on January 3, 2001 and another 50 basis point cut at their meeting on January 31, 2001. While we think that the Fed's actions could provide a temporary lift to U.S. investor and consumer sentiment, our intermediate outlook for the economy remains cautious. The potential for tax cuts in 2001 adds further uncertainty to the economic forecast. Given that the primary effect of the stimulus from a tax cut would occur in 2002 and beyond, monetary policy stimulus will have a greater effect on the U.S. economy near term. Considering only moderate economic recovery in Europe and anemic growth in Japan, we believe that enough distress exists within the economic system to warrant additional easing by the Fed over the coming months. This report contains a summary of market conditions during the annual period and a review of portfolio strategy by your Trust's managers in addition to the Trust's audited financial statements and a detailed list of the portfolio's holdings. Continued thanks for your confidence in BlackRock. We appreciate the opportunity to help you achieve your long-term investment goals. Sincerely, /s/ Laurence D. Fink /s/ Ralph L. Schlosstein Laurence D. Fink Ralph L. Schlosstein Chairman President 1 January 31, 2001 Dear Shareholder: We are pleased to present the audited annual report for The BlackRock Insured Municipal 2008 Term Trust Inc. ("the Trust") for the fiscal year ended December 31, 2000. We would like to take this opportunity to review the Trust's stock price and net asset value (NAV) performance, summarize developments in the fixed income markets and discuss recent portfolio management activity. The Trust is a diversified, actively managed closed-end bond fund whose shares are traded on the New York Stock Exchange under the symbol "BRM." The Trust's investment objective is to manage a portfolio of municipal debt securities that will return $15 per share (an amount equal to the Trust's initial public offering price) to investors on or about December 31, 2008, while providing current income exempt from regular federal income tax. The Trust seeks to achieve this objective by investing in high credit quality ("AAA" or insured to "AAA") tax-exempt general obligation and revenue bonds issued by city, county and state municipalities throughout the United States. The table below summarizes the changes in the Trust's stock price and NAV over the past year: -------------------------------------------------------------------------------------------------------------------- 12/31/00 12/31/99 CHANGE HIGH LOW -------------------------------------------------------------------------------------------------------------------- STOCK PRICE $14.875 $13.75 8.18% $14.9375 $13.375 -------------------------------------------------------------------------------------------------------------------- NET ASSET VALUE (NAV) $16.62 $16.00 3.88% $16.62 $15.54 -------------------------------------------------------------------------------------------------------------------- THE FIXED INCOME MARKETS The rapid expansion of U.S. GDP witnessed throughout much of the period finally slowed dramatically in the third and fourth quarter. After expanding at nearly a 6.0% annualized rate in the first half of the year, growth in the third quarter slowed to 3.0%. Higher oil prices and declines in global equity markets led to declines in consumer spending, residential investment and manufacturing activity. The Federal Reserve raised the discount rate by 0.25% at each of their meetings in November 1999, February 2000, and March 2000 and raised the discount rate by 0.50% in May 2000 to bring the year end discount rate to 6.50%. At their meeting in December 2000, the Federal Reserve left the discount rate unchanged, although it moved towards an easing bias, due to an increasing probability of economic weakness in the foreseeable future. Treasury yields were inverted for much of the year. Yields rose on the short-end of the yield curve in response to the Fed's increases in the discount rate, while yields on the long-end declined below the short-end, particularly in reaction to the announcement that the Treasury would buy back $30 billion of Treasuries with maturities ranging from 10 to 30 years. In the second half of the period, weakening stock markets and signs of slowing growth all caused the bond market to price in a neutral Federal Reserve. This shift in market sentiment caused significant yield curve disinversion during the third quarter of 2000, as yields on the short-end fell relative to yields on the long-end. In the last two months of 2000, the Treasury market rallied significantly on the short-end of the curve, and in December the yield curve regained its characteristic upward slope. For the annual period, the yield on the 10-year Treasury fell from 6.44% on December 31, 1999 to 5.11% on December 31, 2000. During the fourth quarter, the municipal yield curve flattened by 12 bps with 2-year yields declining by 35 bps while 30-year yields declined by 47 bps. Throughout this time frame, municipals continued to outperform taxable spread product while underperforming versus Treasuries. Municipals benefited from retail's continued efforts to diversify out of equities and into fixed income investments as evidenced by the mutual fund industry finally experiencing positive cash flow in the municipal sector during the fourth quarter. Institutional demand for municipal securities has also increased as investors are looking for attractive after tax yields versus Treasuries without the inherent credit risk associated with corporate bonds. 2 THE TRUST'S PORTFOLIO AND INVESTMENT STRATEGY The Trust's portfolio is actively managed to diversify exposure to various sectors, issuers, revenue sources and security types. BlackRock's investment strategy emphasizes a relative value approach, which allows the Trust to capitalize upon changing market conditions by rotating municipal sectors and coupons. Additionally, the Trust emphasizes securities whose maturity dates match the termination date of the Trust. Over the year, trading activity in the Trust remained relatively low, as many of the securities in the Trust's portfolio continued to trade at prices above where they were purchased. As trading activity that results in the Trust realizing a capital gain could require a taxable distribution, as well as reducing the income generating capacity of the Trust, we remain reluctant to realize capital gains at this time. At present, we are confident that the Trust is on schedule to achieve its primary investment objective of returning $15 per share upon termination and will continue to seek investment opportunities in the municipal market. Additionally, the Trust employs leverage to enhance its income by borrowing at short-term municipal rates and investing the proceeds in longer maturity issues that have higher yields. The degree to which the Trust can benefit from its use of leverage may affect its ability to pay monthly income. At the end of the year, the Trust's leverage amount was approximately 37% of total assets. The following chart compares the Trust's current and December 31, 1999 asset composition: SECTOR BREAKDOWN ------------------------------------------------------------------------------- SECTOR DECEMBER 31, 2000 DECEMBER 31, 1999 ------------------------------------------------------------------------------- County, City & State 25% 22% ------------------------------------------------------------------------------- Utility/Power 22% 22% ------------------------------------------------------------------------------- Hospital 12% 15% ------------------------------------------------------------------------------- Education 11% 11% ------------------------------------------------------------------------------- Transportation 7% 6% ------------------------------------------------------------------------------- Lease Revenue 5% 6% ------------------------------------------------------------------------------- Water & Sewer 5% 6% ------------------------------------------------------------------------------- Tax Revenue 5% 5% ------------------------------------------------------------------------------- Special District 5% 3% ------------------------------------------------------------------------------- Housing 2% 3% ------------------------------------------------------------------------------- Industrial & Pollution Control 1% 1% ------------------------------------------------------------------------------- We look forward to managing the Trust to benefit from the opportunities available in the fixed income markets and to meet its investment objectives.

See Notes to Financial Statements. 11 ------------------------------------------------------------------------------- THE BLACKROCK INSURED MUNICIPAL 2008 TERM TRUST INC. NOTES TO FINANCIAL STATEMENTS ------------------------------------------------------------------------------- NOTE 1. ORGANIZATION & The BlackRock Insured ACCOUNTING Municipal 2008 Term Trust POLICIES Inc. (the "Trust"), was orga nized in Maryland on August 7, 1992 as a diversified, closed-end management investment company. The Trust's investment objective is to manage a diversified portfolio of high quality securities that will return $15 per share to investors on or about December 31, 2008 while providing current income exempt from regular federal income tax. The ability of issuers of debt securities held by the Trust to meet their obligations may be affected by economic developments in the specific industry or region. No assurance can be given that the Trust's investment objective will be achieved. The following is a summary of significant accounting policies followed by the Trust: SECURITIES VALUATION: Municipal securities (including commitments to purchase such securities on a "when-issued" basis) are valued on the basis of prices provided by dealers or pricing services approved by the Trust's Board of Directors. In determining the value of a particular security, pricing services may use certain information with respect to transactions in such securities, quotations from bond dealers, market transactions in comparable securities and various relationships between securities in determining values. Short-term securities are valued at amortized cost. Any securities or other assets for which such current market quotations are not readily available are valued at fair value as determined in good faith under procedures established by and under the general supervision and responsibility of the Trust's Board of Directors. SECURITIES TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are recorded on the trade date. Realized and unrealized gains and losses are calculated on the identified cost basis. Interest income is recorded on the accrual basis and the Trust amortizes premium and accretes original issue discount on securities purchased using the interest method. FEDERAL INCOME TAXES: It is the Trust's intention to continue to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute sufficient net income to shareholders. For this reason and because substantially all of the Trust's gross income consists of tax-exempt interest, no Federal income tax provision is required. DIVIDENDS AND DISTRIBUTIONS: The Trust declares and pays dividends and distributions to common shareholders monthly from net investment income, net realized short-term capital gains and other sources, if necessary. Net long-term capital gains, if any, in excess of loss carryforwards may be distributed annually. Dividends and distributions are recorded on the ex-dividend date. Dividends and distributions to preferred shareholders are accrued and determined as described in Note 4. ESTIMATES: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. DEFERRED COMPENSATION PLAN: Under a deferred compensation plan approved by the Board of Directors on February 24, 2000, non-interested Directors may elect to defer receipt of all or a portion of their annual compensation. Deferred amounts earn a return for the Directors as though equivalent dollar amounts had been invested in common shares of other BlackRock funds selected by the Directors. This has the same economic effect for the Directors as if the Directors had invested the deferred amounts in such other BlackRock funds. The deferred compensation plan is not funded and obligations thereunder represent general unsecured claims against the general assets of the Trust. The Trust may, however, elect to invest in common shares of those funds selected by the Directors in order to match its deferred compensation obligations. NEW ACCOUNTING POLICIES: The Trust will adopt the provisions of the AICPA Audit and Accounting Guide for Investment Companies, as revised, effective for fiscal years beginning after December 15, 2000. As required, the Trust will begin amortizing discounts on debt securities effective January 1, 2001. Prior to this date, the Trust amortized premiums and original issue discount on debt securities but did not amortize market discount. The cumulative effect of this accounting change will have no impact on the total net assets of the Trust. The impact of this accounting change is anticipated to have an immaterial effect on the financial statements and will result in an increase to cost of securities and a corresponding decrease in net unrealized appreciation, based on securities held as of December 31, 2000. NOTE 2. AGREEMENTS The Trust has an Investment Advisory Agreement with BlackRock Advisors, Inc., (the "Advisor"), which is a wholly-owned subsidiary of BlackRock, Inc., which in turn is an indirect majority-owned subsidiary of PNC Financial Services Group, Inc. The Trust has an Administration Agreement with Princeton Administrators, L.P. (the "Administrator"), an indirect wholly-owned affiliate of Merrill Lynch & Co., Inc. 12 The investment advisory fee paid to the Advisor is computed weekly and payable monthly at an annual rate of 0.35% of the Trust's average weekly net investment assets. The administration fee paid to the Administrator is also computed weekly and payable monthly at an annual rate of 0.10% of the Trust's average weekly net investment assets. Pursuant to the agreements, the Advisor provides continuous supervision of the investment portfolio and pays the compensation of officers of the Trust who are affiliated persons of the Advisor. The Administrator pays occupancy and certain clerical and accounting costs of the Trust. The Trust bears all other costs and expenses. NOTE 3. PORTFOLIO Purchases and sales of SECURITIES investments, other than short-term investments, for the year ended December 31, 2000, aggregated $81,228,238 and $19,385,536, respectively. The federal income tax basis of the Trust's investments at December 31, 2000, was $665,088,606, and accordingly, gross and net unrealized appreciation was $48,564,476. For federal income tax purposes, the Trust had a capital loss carryforward at December 31, 2000 of approximately $53,000 of which $34,000 will expire in 2007 and $19,000 will expire in 2008. Accordingly, no capital gain distribution is expected to be paid to shareholders until net gains have been realized in excess of such amounts. NOTE 4. CAPITAL There are 200 million shares of $.01 par value common stock authorized. The Trust may classify or reclassify any unissued shares of common stock into one or more series of preferred stock. Of the 27,207,093 common shares outstanding at December 31, 2000, the Advisor owned 7,093 shares. As of December 31, 2000, there were 10,840 preferred shares outstanding as follows: Series T28--2,060, Series R28--2,060, Series T7--4,660, and Series R7--2,060, which includes 2,600 shares of Series T7 issued on March 10, 2000. On March 10, 2000, the Trust reclassified 2,600 shares of common stock and issued an additional 2,600 shares of Series T7 preferred shares. The additional shares issued have identical rights and features of the existing Series T7 preferred shares. Estimated offering costs of $317,160 and underwriting discounts of $650,000 have been charged to paid-in capital in excess of the common shares. Dividends on Series T7 and R7 are cumulative at a rate which is reset every 7 days based on the results of an auction. Dividends on Series T28 are cumulative at a rate which is reset every 28 days based on the results of an auction. Series R28 paid dividends monthly at a rate established at the initial offer- ing through May 17, 1994. Thereafter, rates on Series R28 reset every 28 days based on the results of an auction. Dividend rates ranged from 2.40% to 5.90% during the year ended December 31, 2000. The Trust may not declare dividends or make other distributions on shares of common stock or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding preferred stock would be less than 200%. The preferred stock is redeemable at the option of the Trust, in whole or in part, on any dividend payment date at $25,000 per share plus any accumulated or unpaid dividends whether or not declared. The preferred stock is 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 Trust as set forth in the Articles of Incorporation are not satisfied. The holders of preferred stock have voting rights equal to the holders of common stock (one vote per share) and will vote together with holders of shares of common stock as a single class. However, holders of preferred stock are also entitled to elect two of the Trust's directors. In addition, the Investment Company Act of 1940 requires that along with approval by stockholders that might otherwise be required, the approval of the holders of a majority of any outstanding preferred stock, voting separately as a class would be required to (a) adopt any plan of reorganization that would adversely affect the preferred stock, and (b) take any action requiring a vote of security holders, including, among other things, changes in the Trust's subclassification as a closed-end investment company or changes in its fundamental investment restrictions. NOTE 5. DIVIDENDS Subsequent to December 31, 2000, the Board of Directors of the Trust declared a dividend from undistributed earnings of $0.06625 per common share payable, February 1, 2001 to shareholders of record on January 16, 2001. For the period January 1, 2001 to January 31, 2001 dividends declared on preferred shares totalled $920,230 in aggregate for the four outstanding preferred share series. 13 ------------------------------------------------------------------------------- THE BLACKROCK INSURED MUNICIPAL 2008 TERM TRUST INC. REPORT OF INDEPENDENT AUDITORS ------------------------------------------------------------------------------- The Shareholders and Board of Directors of The BlackRock Insured Municipal 2008 Term Trust Inc.: We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of The BlackRock Insured Municipal 2008 Term Trust Inc., (the "Trust") as of December 31, 2000, and the related statement of operations for the year then ended, and 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 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 auditing standards generally accepted in the United States of America. 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. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned at December 31, 2000 by correspondence with the custodian. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of The BlackRock Insured Municipal 2008 Term Trust Inc. as of December 31, 2000, and the results of its operations, the changes in its net assets and its financial highlights for the respective stated periods in conformity with accounting principles generally accepted in the United States of America. /s/ Deloitte & Touche LLP New York, New York February 9, 2001 14 -------------------------------------------------------------------------------- THE BLACKROCK INSURED MUNICIPAL 2008 TERM TRUST INC. TAX INFORMATION -------------------------------------------------------------------------------- We are required by the Internal Revenue Code to advise you within 60 days of the Trust's tax year end as to the federally tax-exempt interest dividends received by you during such fiscal year. Accordingly, we are advising you that all dividends, common and preferred, paid by the Trust during the fiscal year were federal tax-exempt interest dividends. For purposes of preparing your annual federal income tax return, you should report the amounts as reflected on the appropriate form 1099-DIV or substitute 1099 DIV. -------------------------------------------------------------------------------- DIVIDEND REINVESTMENT PLAN -------------------------------------------------------------------------------- Pursuant to the Trust's Dividend Reinvestment Plan (the "Plan"), common shareholders may elect to have all distributions of dividends and capital gains reinvested by State Street Bank and Trust Company (the "Plan Agent") in Trust shares pursuant to the Plan. Shareholders who do not participate in the Plan will receive all distributions in cash paid by check in United States dollars mailed directly to the shareholders of record (or if the shares are held in street or other nominee name, then to the nominee) by the transfer agent, as dividend disbursing agent. The Plan Agent serves as agent for the shareholders in administering the Plan. After the Trust declares a dividend or determines to make a capital gain distribution, the Plan Agent will, as agent for the participants, receive the cash payment and use it to buy Trust shares in the open market on the New York Stock Exchange or elsewhere for the participants' accounts. The Trust will not issue any new shares under the Plan. Participants in the Plan may withdraw from the Plan upon written notice to the Plan Agent and will receive certificates for whole Trust shares and a cash payment for any fraction of a Trust share. The Plan Agent's fees for the handling of the reinvestment of dividends and distributions will be paid by the Trust. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent's open market purchases in connection with the reinvestment of dividends and distributions. The automatic reinvestment of dividends and distributions will not relieve participants of any federal income tax that may be payable on such dividends or distributions. The Trust reserves the right to amend or terminate the Plan as applied to any dividend or distribution paid subsequent to written notice of the change sent to all shareholders of the Trust at least 90 days before the record date for the dividend or distribution.

INVESTMENT SUMMARY -------------------------------------------------------------------------------- THE TRUST'S INVESTMENT OBJECTIVE: The BlackRock Insured Municipal2008 Term Trust's investment objective is to provide current income exempt from regular Federal income tax and to return $15 per share (the initial public offering price per share) to investors on or about December 31, 2008. WHO MANAGES THE TRUST? BlackRock Advisors, Inc. (the "Advisor") is an SEC-registered investment advisor. As of December 31, 2000, the Advisor and its affiliates (together, "BlackRock") managed $204 billion on behalf of taxable and tax-exempt clients worldwide. Strategies include fixed income, equity and cash and may incorporate both domestic and international securities. Domestic fixed income strategies utilize the government, mortgage, corporate and municipal bond sectors. BlackRock managed twenty-one closed-end funds that are traded on either the New York or American stock exchanges, and a $26 billion family of open-end funds. BlackRock's 301 clients are domiciled in the United States and overseas. WHAT CAN THE TRUST INVEST IN? The Trust intends to invest at least 80% of its total assets in a diversified portfolio of municipal obligations insured as to the timely payment of both principal and interest. The Trust may invest up to 20% of its total assets in uninsured municipal obligations which are rated Aaa by Moody's or AAA by S&P, or are determined by the Advisor to be of comparable credit quality (guaranteed, escrowed or backed in trust). WHAT IS THE ADVISOR'S INVESTMENT STRATEGY? The Advisor will seek to meet the Trust's investment objective by managing the assets of the Trust so as to return the initial offering price ($15 per share) at maturity. The Advisor will implement a conservative strategy that will seek to closely match the maturity or call provisions of the assets of the portfolio with the future return of the initial investment at the end of 2008. At the Trust's termination, BlackRock expects that the value of the securities which have matured, combined with the value of the securities that are sold or called, if any, will be sufficient to return the initial offering price to investors. On a continuous basis, the Trust will seek its objective by actively managing its portfolio of municipal obligations and retaining a small portion of its income each year. In addition to seeking the return of the initial offering price, the Advisor also seeks to provide current income exempt from regular Federal income tax to investors. The portfolio managers will attempt to achieve this objective by investing in securities that provide competitive income. In addition, leverage will be used to enhance the income of the portfolio. In order to maintain competitive yields as the Trust approaches maturity and depending on market conditions, the Advisor will attempt to purchase securities with call protection or maturities as close to the Trust's maturity date as possible. Securities with call protection should provide the portfolio with some degree of protection against reinvestment risk during times of lower prevailing interest rates. Since the Trust's primary goal is to return the initial offering price at maturity, any cash that the Trust receives prior to its maturity date will be reinvested in securities with maturities which coincide with the remaining term of the Trust. It is important to note that the Trust will be managed so as to preserve the integrity of the return of the initial offering price. If market conditions, such as interest rate volatility, force a choice between current income and risking the return of the initial offering price, it is likely the return of the initial offering price will be emphasized. HOW ARE THE TRUST'S SHARES PURCHASED AND SOLD? DOES THE TRUST PAY DIVIDENDS REGULARLY? The Trust's common shares are traded on the New York Stock Exchange which provides investors with liquidity on a daily basis. Orders to buy or sell shares of the Trust must be placed through a registered broker or financial advisor. The Trust pays monthly dividends which are typically paid on the first business day of the month. For shares held in the shareholder's name, dividends may be reinvested in additional shares of the Trust through the Trust's transfer agent, State Street Bank and Trust Company. Investors who wish to hold shares in a brokerage account should check with their financial advisor to determine whether their brokerage firm offers dividend reinvestment services. 16 LEVERAGE CONSIDERATIONS IN A TERM TRUST Under current market conditions, leverage increases the income earned by the Trust. The Trust employs leverage primarily through the issuance of preferred stock. Leverage permits the Trust to borrow money at short-term rates and reinvest that money in longer-term assets which typically offer higher interest rates. The difference between the cost of the borrowed funds and the income earned on the proceeds that are invested in longer term assets is the benefit to the Trust from leverage. Leverage also increases the duration (or price volatility of the net assets) of the Trust, which can improve the performance of the Trust in a declining rate environment, but can cause net assets to decline faster than the market in a rapidly rising rate environment. The Advisor's portfolio managers continuously monitor and regularly review the Trust's use of leverage and the Trust may reduce, or unwind, the amount of leverage employed should the Advisor consider that reduction to be in the best interests of the shareholders. SPECIAL CONSIDERATIONS AND RISK FACTORS RELEVANT TO TERM TRUSTS THE TRUST IS INTENDED TO BE A LONG-TERM INVESTMENT AND IS NOT A SHORT-TERM TRADING VEHICLE. RETURN OF INITIAL INVESTMENT. Although the objective of the Trust is to return its initial offering price upon termination, there can be no assurance that this objective will be achieved. DIVIDEND CONSIDERATION. The income and dividends paid by the Trust are likely to decline to some extent over the term of the Trust due to the anticipated shortening of the dollar-weighted average maturity of the Trust's assets. LEVERAGE. The Trust utilizes leverage through the issuance of preferred stock, which involves special risks. The Trust's net asset value and market value may be more volatile due to its use of leverage. MARKET PRICE OF SHARES. The shares of closed-end investment companies such as the Trust trade on the New York Stock Exchange (NYSE symbol: BRM) and as such are subject to supply and demand influences. As a result, shares may trade at a discount or a premium to their net asset value. ILLIQUID SECURITIES. The Trust may invest in securities that are illiquid, although under current market conditions the Trust expects only to do so to a limited extent. An investment in these securities involves special risks. ANTITAKEOVER PROVISIONS. Certain antitakeover provisions will make a change in the Trust's business or management more difficult without the approval of the Trust's Board of Directors and may have the effect of depriving shareholders of an opportunity to sell their shares at a premium above the prevailing market price. MUNICIPAL OBLIGATIONS. Municipal obligations include debt obligations issued by states, cities, and local authorities, and possessions and certain territories of the United States to obtain funds for various public purposes, including the construction of public facilities, the refinancing of outstanding obligations and the obtaining of funds for general operating expenses and for loans to other public institutions and facilities. The value of municipal debt securities generally varies inversely with changes in prevailing market interest rates. Depending on the amount of call protection that the securities in the Trust have, the Trust may be subject to certain reinvestment risks in environments of declining interest rates. ALTERNATIVE MINIMUM TAX (AMT). The Trust may invest in securities subject to AMT. The Trust currently holds no securities that are subject to AMT. 17 ------------------------------------------------------------------------------- THE BLACKROCK INSURED MUNICIPAL 2008 TERM TRUST INC.
