662 SHARES, SERIES T7

The BlackRock Investment Quality Municipal Trust Inc. (the "Trust") is a closed-end, diversified management investment company. The Trust's investment objective is to provide high current income exempt from regular Federal income tax consistent with the preservation of capital.

The Trust seeks to achieve its investment objective by investing substantially all of its assets in a diversified portfolio of investment grade municipal obligations and to actively manage its assets in relation to market conditions and interest rate changes. Under normal circumstances, the Trust invests at least 80% of its assets in securities which are rated at the time of investment at least Baa, MIG or P-1 by Moody's Investors Service, Inc. ("Moody's"), BBB, SP-2 or A-1 by Standard & Poor's Rating Service ("S&P"), or BBB or F-1 by Fitch Investors Service, Inc. ("Fitch") or another nationally recognized statistical rating organization. The Trust may invest up to 20% of its assets in unrated securities that are deemed by the Trust's investment adviser to be equivalent credit quality. No assurance can be given that the Trust will achieve its investment objective. Although the Trust does not ordinarily invest in municipal obligations the interest on which is subject to the Federal alternative minimum tax and expects that no more than 20% of its assets will be invested in municipal obligations subject to such tax at any time, all or a portion of the Trust's dividends may be subject to Federal alternative minimum tax. BlackRock Financial Management, Inc. (the "Adviser") acts as the investment adviser to the Trust.

The underwriters are offering the New Preferred Shares subject to various conditions. The underwriters expect to deliver the New Preferred Shares to purchasers, in book-entry form, through the facilities of The Depository Trust Company on or about ___, 2000.

February , 2000

The Trust is offering 662 newly issued shares of Auction Rate Municipal Preferred Stock, Series T7. We refer to these shares as the "New Preferred Shares" throughout this prospectus and the related statement of additional information. Except for the initial dividend rate and initial dividend period, the terms of the New Preferred Shares are the same as the terms of the Trust's currently outstanding Series T7 Preferred Shares (together with the Trust's outstanding Series T28 Preferred Shares, the "Preferred Shares").

The dividend rate for the initial dividend period (the period from the date of issue through ____, 2000) will be ___%, and will be paid on _________, 2000. After the initial dividend period, the dividend rate on the New Preferred Shares for each subsequent dividend period generally will be determined pursuant to weekly auctions. The letter/numeral indication "T7" means that the auction for the New Preferred Shares normally will be held every Tuesday and that the dividend period normally will be 7 days. Prospective purchasers should carefully review the auction procedures described in this prospectus, including the appendices, and should note:

o a buy order (called a "bid") or sell order is a commitment to buy or sell New Preferred Shares based on the results of an auction;

o auctions will be conducted by telephone; and

o purchases and sales will be settled on the next business day after the auction.

The New Preferred Shares will not be listed on an exchange. You may only buy or sell New Preferred Shares through an order placed at an auction with or through a broker-dealer that has entered into an agreement with the auction agent and the Trust, or in a secondary market maintained by certain broker-dealers. These broker-dealers are not required to maintain this market, and it may not provide you with liquidity.

Dividends on New Preferred Shares, to the extent payable from tax-exempt income earned on the Trust's investments, will be exempt from regular Federal income tax in the hands of owners of such shares. All or a portion of the Trust's dividends may be subject to the Federal alternative minimum tax. The Trust is required to allocate net capital gains and other taxable income, if any, proportionately between common shares and Preferred Shares, including the New Preferred Shares, based on the percentage of total dividends distributed to each class for that year. The Trust may at its election give notice of the amount of any income subject to regular Federal income tax to be included in a dividend on a New Preferred Share in advance of the related auction. If the Trust does not give such advance notice, it generally will be required to pay additional amounts to holders of New Preferred Shares in order to adjust for their receipt of income subject to regular Federal income tax.

The New Preferred Shares are redeemable, in whole or in part, at the option of the Trust on any date dividends are paid on the New Preferred Shares (except during certain non-call periods), and will be subject to mandatory redemption, in certain circumstances, at a redemption price of $25,000 per share plus accumulated but unpaid dividends to the redemption date (whether or not declared), plus a premium in certain circumstances.

The New Preferred Shares do not represent a deposit or obligation of, and are not guaranteed or endorsed by, any bank or other insured depository institution. The New Preferred Shares are not federally insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

YOU SHOULD RELY ONLY ON THE INFORMATION CONTAINED IN THIS PROSPECTUS. THE TRUST HAS NOT AUTHORIZED ANYONE TO PROVIDE YOU WITH DIFFERENT INFORMATION. THE TRUST IS NOT MAKING AN OFFER OF THESE SECURITIES IN ANY STATE WHERE THE OFFER IS NOT PERMITTED. YOU SHOULD NOT ASSUME THAT THE INFORMATION PROVIDED BY THIS PROSPECTUS IS ACCURATE AS OF ANY DATE OTHER THAN THE DATE ON THE FRONT OF THIS PROSPECTUS.

                                                     Exchange under the symbol "BKN."

THE OFFERING.......................................  The Trust is offering 662 New Preferred Shares.  The purchase
                                                     price for each New Preferred Share is $25,000 plus accumulated
                                                     dividends, if any, from the date the share is first issued. Except
                                                     for the initial dividend rate and the length of the initial dividend
                                                     period for the New Preferred Shares, the rights and preferences
                                                     of the New Preferred Shares are the same as the Trust's
                                                     outstanding Series T7 preferred shares.

                                                     The New Preferred Shares are being offered by a group of
                                                     underwriters listed under "Underwriting."

INVESTMENT OBJECTIVE AND POLICIES..................  The Trust's investment objective is to provide high current
                                                     income exempt from regular Federal income tax consistent with
                                                     the preservation of capital.  No assurance can be given that the
                                                     Trust will achieve its investment objective.  Although the Trust
                                                     does not ordinarily invest in municipal obligations subject to the
                                                     Federal alternative minimum tax ("AMT") and expects that no
                                                     more than 20% of its assets will be invested in municipal
                                                     obligations subject to such tax at any time, all or a portion of the
                                                     Trust's dividends may be subject to AMT.

                                                     In seeking to provide high current income exempt from
                                                     regular Federal income tax, the Trusts intends to invest
                                                     substantially all of its assets in a diversified portfolio
                                                     of investment grade municipal obligations and to actively
                                                     manage its assets in relation to market conditions and
                                                     interest rate changes. Under normal circumstances, the Trust
                                                     will invest at least 80% of its assets in securities which
                                                     are rated at the time of investment at least Baa, MIG or P-1
                                                     by Moody's, BBB, SP-2 or A-1 by S&P, or BBB or F-1 by Fitch
                                                     or another nationally recognized statistical rating
                                                     organization. The Trust may invest up to 20% of its assets
                                                     in unrated securities that are deemed by the Trust's
                                                     investment adviser to be of equivalent credit quality. The
                                                     Trust emphasizes investments in municipal obligations with
                                                     long-term maturities and ordinarily maintains an average
                                                     portfolio maturity of 20-30 years, but the average maturity
                                                     may be shortened from time to time depending on market
                                                     conditions.

INVESTMENT ADVISER.................................  BlackRock Financial Management, Inc. (the "Adviser") acts as
                                                     the Trust's investment adviser.  The Adviser is responsible for
                                                     the investment strategy of the Trust.  The Adviser and its
                                                     affiliates comprise a global asset management firm with assets of
                                                     approximately $148 billion under management as of September 30,
                                                     1999.

RISK FACTORS.......................................  Before investing in New Preferred Shares, you should consider
                                                     carefully the following risks of such an investment:

                                                     o    if an auction fails you may not be able to sell some or all
                                                          of your shares;

                                                     o    because of the nature of the market for New Preferred
                                                          Shares, you may receive less than the price you paid
                                                          for your shares if you sell them outside of the
                                                          auction, especially when market interest rates are
                                                          rising;

                                                     o    a rating agency could downgrade the rating assigned to
                                                          the New Preferred Shares, which could affect liquidity;

                                                     o    the Trust may be forced to redeem your shares to meet
                                                          regulatory or rating agency requirements or may
                                                          voluntarily redeem your shares in certain
                                                          circumstances;

                                                     o    in extraordinary circumstances the Trust may not earn
                                                          sufficient income from its investments to pay dividends;

                                                     o    if interest rates rise, the value of the Trust's
                                                          investment portfolio will decline, reducing the asset
                                                          coverage for the New Preferred Shares; and

                                                     o    if an issuer of a municipal bond in which the Trust
                                                          invests experiences financial difficulty or defaults,
                                                          there may be a negative impact on the income and net
                                                          asset value of the Trust's portfolio.

SECONDARY MARKET TRADING...........................  The New Preferred Shares will not be listed on a stock exchange.
                                                     Instead, you may buy or sell New Preferred Shares at a periodic
                                                     auction by submitting orders to a broker-dealer (a "Broker-
                                                     Dealer") that has entered into a separate agreement with the
                                                     auction agent and the Trust or to a broker-dealer that has entered
                                                     into an agreement with a Broker-Dealer.  In addition to the
                                                     auctions, Broker-Dealers and other broker-dealers may maintain
                                                     a separate secondary trading market in New Preferred Shares, but
                                                     may discontinue this activity at any time.  You may transfer
                                                     shares outside of auctions only to or through a Broker-Dealer, a
                                                     broker-dealer that has entered into a separate agreement with a
                                                     Broker-Dealer, or other persons as the Trust may agree. There
                                                     can be no assurance that a secondary trading market for the New
                                                     Preferred Shares will develop, or if it does develop, that it will
                                                     provide holders with liquidity of investment.

DIVIDENDS AND DIVIDEND PERIODS.....................  After their initial dividend period, the New Preferred Shares
                                                     normally will have a dividend period consisting of seven days.
                                                     The board of directors of the Trust may, from time to time,
                                                     declare a special dividend period upon giving notice to the
                                                     holders of the New Preferred Shares.

                                                     Dividends on the New Preferred Shares offered hereby are
                                                     cumulative from the date they are first issued and are
                                                     payable when, as and if declared by the board of directors
                                                     of the Trust, out of funds legally available therefor. The
                                                     Trust will pay the initial dividend for the New Preferred
                                                     Shares on [____________] and thereafter generally on each
                                                     succeeding Wednesday, subject to certain exceptions.

                                                     After the initial dividend period, the dividend rate for the
                                                     New Preferred Shares will be determined by auction. The
                                                     dividend rate for the initial dividend period is ___% and
                                                     the first auction will be held on ___.

TAXES..............................................  Because in normal circumstances the Trust will invest
                                                     substantially all of its assets in municipal obligations that pay
                                                     interest that is exempt from regular Federal income tax, the
                                                     income you receive will ordinarily be exempt from Federal income
                                                     tax. Your income may be subject to state and local taxes. Taxable
                                                     income or gain earned by the Trust will be allocated
                                                     proportionately to holders of the Trust's preferred shares and
                                                     common shares, based on the percentage of total dividends paid
                                                     to each class for that year. Accordingly, certain specified New
                                                     Preferred Share dividends may be subject to income tax on
                                                     income or gains attributed to the Trust. The Trust may at its
                                                     election give notice before any applicable auction of the amount
                                                     of any taxable income and gain to be distributed for the period
                                                     relating to that auction. If the Trust does not provide such
                                                     notice, the Trust generally will make holders of New Preferred
                                                     Shares whole for taxes owing on dividends paid to shareholders
                                                     that include taxable income or gain.

ALTERNATIVE MINIMUM TAX............................  Although the Trust does not ordinarily invest in municipal
                                                     obligations subject to AMT, all or a portion of the Trust's
                                                     dividends may be subject to AMT. New Preferred Shares may
                                                     not be a suitable investment if you are subject to this tax or
                                                     would become subject to such tax by investing in New Preferred
                                                     Shares.

LIQUIDATION PREFERENCE.............................  The liquidation preference of each New Preferred Share will be
                                                     $25,000, plus an amount equal to accumulated but unpaid
                                                     dividends (whether or not earned or declared) plus the premium,
                                                     if any, resulting from the designation of a premium call period.

RATINGS............................................  It is a condition to the issuance of the New Preferred Shares that
                                                     they be issued with a rating of "aaa" from Moody's and "AAA"
                                                     from S&P and that the Trust receive written assurance from each
                                                     of Moody's and S&P that the issuance of the New Preferred
                                                     Shares will not cause a downgrading of the Trust's currently
                                                     outstanding Preferred Shares.

REDEMPTION.........................................  Holders of New Preferred Shares will not have the right to cause
                                                     the Trust to redeem their shares.  The Trust may, however, be
                                                     required by applicable law or by rating agency guidelines to
                                                     redeem New Preferred Shares if, for example, the Trust does not
                                                     meet an asset coverage ratio required by law or correct a failure
                                                     to meet a rating agency guideline in a timely manner.  The Trust
                                                     may also voluntarily redeem New Preferred Shares.

VOTING RIGHTS......................................  The Investment Company Act of 1940 requires that the holders
                                                     of New Preferred Shares and of currently outstanding Preferred
                                                     Shares, voting together as a single class separate from the
                                                     holders of common shares, have the right to elect at least two
                                                     directors of the Trust at all times and to elect a majority of the
                                                     directors at any time when two years' dividends on the Preferred
                                                     Shares are unpaid.  The holders of New Preferred Shares and any
                                                     other outstanding preferred shares will vote as a separate class
                                                     on certain other matters as required under the Trust's
                                                     charter, the Investment Company Act of 1940 and Maryland
                                                     law.

THE TRUST

The BlackRock Investment Quality Municipal Trust Inc. (the "Trust") is a diversified, closed-end management investment company. The Trust was incorporated under the laws of the State of Maryland on November 19, 1992, and has registered under the Investment Company Act of 1940 (the "1940 Act"). The Trust's principal office is located at 800 Scudders Mill Road, Plainsboro, New Jersey 08536 and its telephone number is (800) 688-0928.

The Trust commenced investment operations on February 26, 1993, upon the closing of the initial public offering of 15,500,000 of its common shares. The net proceeds of such offering were approximately $218.6 million. In March, 1993, the Trust sold, pursuant to an over-allotment option granted to the underwriters in the initial public offering, an additional 1.2 million of its common shares for net proceeds of approximately $14.1 million.

On March 26, 1993, the Trust issued shares of preferred stock in the following amounts and with the following designations: Preferred Shares Series T7 - 1,300 shares and Preferred Shares Series T28 - 1,300 shares. Each series of preferred shares was issued with a liquidation preference per share of $50,000, plus accumulated and unpaid dividends. On May 16, 1995, shareholders approved a proposal to split each preferred share into two shares and simultaneously reduce each share's liquidation preference from $50,000 to $25,000, plus in each case accumulated and unpaid dividends, which split occurred on July 24, 1995.

As of December 31, 1999, $16,707,093 common shares of the Trust were outstanding and 5,200 preferred shares were outstanding in two series:
2,600 Preferred Shares Series T7 and 2,600 Preferred Shares Series T28. The Trust's common shares are traded on the New York Stock Exchange under the symbol "BKN."

The following table provides information about the Preferred Shares since their issuance:

USE OF PROCEEDS

The net proceeds of the offerings will be $[ ], after payment of offering expenses (estimated to be $300,000) and the underwriting discount.

The net proceeds of the offering will be invested in accordance with the Trust's investment objective and policies as stated below. It is presently anticipated that the Trust will be able to invest substantially all of the net proceeds in municipal securities that meet its objective and policies at or shortly (within [six to eight] weeks) after the completion of the offering. To the extent that all of the proceeds cannot be so invested, pending such investment, they will be invested in short-term, high quality tax-exempt securities. If necessary in order to fully invest the net proceeds of the offerings immediately, the Trust may also purchase, as temporary investments, short-term, taxable investments, the income on which is subject to regular Federal income tax.

INVESTMENT OBJECTIVE AND POLICIES

The Trust's investment objective is to provide high current income exempt from regular Federal income tax consistent with the preservation of capital. No assurance can be given that the Trust will achieve its investment objective.

The Trust seeks to achieve its investment objective by investing substantially all of its assets in a diversified portfolio of investment grade municipal obligations and actively managing its assets in relation to market conditions and interest rate changes. Under normal circumstances, the Trust will invest at least 80% of its assets in securities rated investment grade by Moody's (at least Baa, MIG or P-1), S&P (at least BBB, SP-2 or A-1), Fitch (at least BBB or F-1) or another nationally recognized statistical rating agency. The Trust may invest up to 20% of its assets in unrated securities that are deemed by the Adviser to be of equivalent credit quality. The Trust does not ordinarily invest more than 25% of its total assets (taken at market value) in municipal obligations whose issuers are located in the same state. The Trust emphasizes investments in municipal obligations with long-term maturities and expects to maintain an average portfolio maturity of 20-30 years, but the average maturity may be shortened from time to time depending on market conditions. Although the Trust does not currently intend to invest in municipal obligations the interest on which would be subject to AMT and expects that no more than 20% of its assets will be invested in municipal obligations subject to such tax at any time, all or a portion of the Trust's dividends paid in respect of the New Preferred Shares may be subject to AMT.

In addition, the Trust may utilize certain options, futures, interest rate swaps and related transactions for hedging purposes. To the extent the Trust utilizes such hedging strategies or invests in taxable securities, the Trust's ability to achieve its investment objective of providing high current income exempt from regular Federal income tax may be limited. Accordingly, under normal circumstances, the Trust expects that its use of such practices will not be significant.

For purposes of enhancing liquidity and/or preserving capital, on a temporary defensive basis, the Trust may invest without limit in securities issued by the U.S. Government or its agencies or instrumentalities, repurchase agreements collateralized by such securities, or certificates of deposit, time deposits or bankers' acceptances. The Trust may also invest in municipal obligations with maturities of less than one year, other debt obligations of corporate issuers, such as interest-paying corporate bonds, commercial paper and certificates of deposit, bankers' acceptances and interest- bearing savings accounts of banks having assets greater than $1 billion and which are members of the Federal Deposit Insurance Corporation. During temporary defensive periods, the current dividend rate on any outstanding preferred stock will be more likely to approximate or exceed the net rate of return on the Trust's investment portfolio, with the result that the leverage resulting from the preferred stock may become less beneficial or adverse to the holders of common shares.

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. These purposes include the construction of public facilities such as airports, bridges, highways, housing, hospitals, mass transportation, schools, streets and water and sewer works. Other public purposes for which municipal obligations may be issued include the refinancing of outstanding obligations and the obtaining of funds for general operating expenses and for loans to other public institutions and facilities. Subject to the credit standard policies described under "Investment Objective and Policies," there are two categories of municipal obligations in which the Trust may invest in normal circumstances: (i) "public purpose" obligations that generate interest that is tax-exempt under regular Federal income tax rules and is not treated as a preference item for AMT; and (ii) qualified "private activity" obligations (typically industrial revenue bonds) that generate income that is tax-exempt under regular Federal income tax rules but must, if issued after August 7, 1986, be included in computing AMT. The Trust will not invest in municipal obligations that generate interest that by its terms is subject to Federal income tax other than AMT.

The types of municipal obligations in which the Trust may invest include general obligation bonds, revenue bonds, municipal lease obligations, installment purchase contract obligations, capped variable and floating rate obligations, zero coupon securities, custodial receipts or certificates, auction and residual component municipal securities, tax-exempt notes and municipal commercial paper.

The yields on municipal obligations are dependent on a variety of factors, including interest and income tax rates, the condition of the general money market and the municipal obligations market, the size of the particular issue, the maturity of the obligation and the rating of the issue. The ratings of Moody's, S&P and Fitch represent their opinions as to the quality of those municipal obligations that they rate.

It should be emphasized that ratings are general and are not absolute standards of quality. Consequently, municipal obligations with the same maturity, coupon and rating may have different yields while obligations of the same maturity and coupon with different ratings may have the same yield. The market value of outstanding municipal obligations will vary with changes in prevailing interest rate levels and as a result of changing evaluations of the ability of their issuers to meet interest and principal payments.

The terms of municipal obligations often give their issuers the right periodically to "call" or prepay their municipal obligations. Issuers will exercise call rights when interest rates decline and they can refinance their municipal obligations at lower interest rates. At the time the Trust was formed, most of the municipal obligations available in the market were subject to call provisions. When municipal obligations are called by their issuers, the Adviser reinvests the proceeds from the called securities in other municipal obligations and is subject to reinvestment risk.

Obligations of issuers of municipal obligations may be subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the United States Bankruptcy Code and other applicable laws. In addition, the obligations of such issuers may become subject to the laws enacted in the future by Congress or state legislatures or referenda extending the time for payment of principal and/or interest, or imposing other constraints upon enforcement of such obligations or upon municipalities to levy taxes. There is also the possibility that, as a result of legislation or other conditions, the power or ability of any issuer to pay, when due, the principal of and interest on its municipal obligations may be materially affected.

INVESTMENT GRADE MUNICIPAL OBLIGATIONS

The Trust invests substantially all of its assets in municipal obligations rated investment grade at the time of purchase. The lowest investment grade rating for municipal obligations is "BBB" by S&P, "Baa" by Moody's or "BBB" by Fitch. "BBB" municipal obligations (including those rated as low as BBB-) are considered by S&P as having "adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to meet its financial commitment on the obligation." "Baa" municipal obligations (including those rated as low as Baa3) are considered by Moody's "as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such municipal obligations lack outstanding investment characteristics and in fact have speculative characteristics as well." "BBB" municipal obligations (including those rated as low as BBB-) are considered by Fitch to be "of satisfactory credit quality. The obligor's ability to pay interest and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to have adverse consequences on these municipal obligations, and therefore impair timely payment." The Trust's ability to preserve principal is a function of, among other things, the ability of the issuers of municipal obligations in which the Trust invests to make timely payments of interest and principal and the ability of the Adviser to select and monitor such securities and to seek to minimize the potential adverse impact of rating downgrades.

OTHER INVESTMENT PRACTICES

Certain of the other investment practices in which the Trust may engage that are described herein or in the statement of additional information may give rise to income that is subject to regular Federal income tax. Accordingly, in normal circumstances, the Trust does not intend to engage in such practices to a significant extent. Moreover, the Trust intends that, so long as New Preferred Shares are outstanding, its portfolio will reflect guidelines established by Moody's and S&P in connection with the Trust's receipt of a rating for such shares on the date they are first issued of at least "aaa" from Moody's and "AAA" from S&P. Such guidelines may preclude or limit the Trust from engaging in many of the investment practices described under this caption or in the statement of additional information. In particular, for so long as New Preferred Shares are rated by Moody's, unless the Moody's ratings guidelines change from those presently applicable as described under "Description of New Preferred Shares -- Rating Agency Guidelines and Asset Coverage," the Trust will not buy or sell futures contracts or options thereon or write put or call options (except covered call options) on portfolio securities unless it receives written confirmation from Moody's that engaging in such transactions would not impair the ratings then assigned to the New Preferred Shares by Moody's except that the Trust may sell exchange traded futures contracts based on the Municipal Index or Treasury Bonds and purchase exchange traded put options on such futures contracts and write exchange traded call options on such futures contracts (collectively "Moody's Hedging Transactions") subject to the limitations described below. For so long as New Preferred Shares are rated by S&P, unless S&P's ratings guidelines change from those presently applicable as described under "Description of New Preferred Shares -- Rating Agency Guidelines and Asset Coverage," the Trust will not buy or sell futures contracts or options thereon or write put options (except covered put options) or call options (except covered call options) on portfolio securities unless it receives written confirmation from S&P that engaging in such transactions will not impair the ratings then assigned to the New Preferred Shares by S&P except that the Trust may buy and sell futures contracts based on the Municipal Index or Treasury Bonds and purchase put and call options on such contracts (collectively "S&P Hedging Transactions") subject to the limitations described below.

HEDGING

Although in normal circumstances the Trust does not intend to invest more than 5% of its assets in instruments other than municipal obligations, the Trust may also enter into certain hedging transactions. In particular, the Trust may purchase and sell futures contracts, exchange-listed and over-the-counter put and call options on securities, financial indices and futures contracts and may enter into various interest rate transactions (collectively, "Hedging Transactions"). Hedging Transactions may be used to attempt to protect against possible changes in the market value of the Trust's portfolio resulting from fluctuations in the debt securities markets and changes in interest rates, to protect the Trust's unrealized gains in the value of its portfolio securities, to facilitate the sale of such securities, for investment purposes or to establish a position in the securities markets as a temporary substitute for purchasing particular securities. Any or all of these techniques may be used at any time. There is no particular strategy that requires use of one technique rather than another. Use of any Hedging Transaction is a function of market conditions. The Hedging Transactions that the Trust may use are described in the statement of additional information. The ability of the Trust to hedge successfully will depend on the Adviser's ability to predict pertinent market movements, which cannot be assured.

OTHER INVESTMENT TECHNIQUES

The Trust may engage in other types of transactions, including investment in restricted and illiquid securities, repurchase and reverse repurchase agreements, when-issued and forward commitment transactions, borrowing, securities lending and other transactions. For a description of such types of transactions, see "Investment Policies and Techniques - Other Investment Policies and Techniques" in the statement of additional information.

RISKS

Risk is inherent in all investing. Investing in any investment company security involves risk, including the risk that you may receive little or no return on your investment or that you may lose part or all of your investment. Therefore, before investing you should consider carefully the following risks that you assume when you invest in New Preferred Shares.

INTEREST RATE RISK

The Trust issues preferred shares (including the New Preferred Shares), which pay dividends based on short-term interest rates. The Trust then uses the proceeds from the sale of preferred shares to buy municipal obligations, which pay interest based on long-term rates. Both long-term and short-term interest rates may fluctuate. If short-term interest rates rise, the preferred shares dividend rates may rise so that the amount of dividends paid to holders of preferred shares exceeds the income from the portfolio securities purchased with the proceeds from the sale of preferred shares. Because income from the Trust's entire investment portfolio (not just the portion of the portfolio purchased with the proceeds of the preferred shares offering) is available to pay preferred share dividends, however, preferred share dividend rates would need to greatly exceed the yield on the Trust's portfolio before the Trust's ability to pay preferred share dividends would be impaired. Generally, municipal obligations will decrease in value when interest rates rise and increase in value when interest rates decline. If long-term rates rise, the value of the Trust's investment portfolio will decline, reducing the amount of assets serving as asset coverage for the preferred shares.

AUCTION RISK

The dividend rate for the New Preferred Shares normally is set through an auction process. In the auction, holders of New Preferred Shares may indicate the dividend rate at which they would be willing to hold or sell their New Preferred Shares or purchase additional New Preferred Shares. The auction also provides liquidity for the sale of New Preferred Shares. An auction fails if there are more New Preferred Shares offered for sale than there are buyers. You may not be able to sell your New Preferred Shares at an auction if the auction fails. Also, if you place hold orders (orders to retain New Preferred Shares) at an auction only at a specified dividend rate, and that rate exceeds the rate set at the auction, you will not retain your New Preferred Shares. Finally, if you buy shares or elect to retain shares without specifying a dividend rate below which you would not wish to buy or continue to hold those shares, you could receive a lower rate of return on your shares than the market rate. See "The Auction".

SECONDARY MARKET RISK

If you try to sell your New Preferred Shares between auctions, you may not be able to sell any or all of your shares, or you may not be able to sell them for $25,000 per share or $25,000 per share plus accumulated dividends. If the Trust has designated a Special Dividend Period (a rate period of more than seven days), changes in interest rates could affect the price you would receive if you sold your shares in the secondary market. Broker-dealers that maintain a secondary trading market for New Preferred Shares are not required to maintain this market, and the Trust is not required to redeem shares either if an auction or an attempted secondary market sale fails because of a lack of buyers. New Preferred Shares are not listed on a stock exchange or the NASDAQ stock market. If you sell your New Preferred Shares to a broker-dealer between auctions, you may receive less than the price you paid for them, especially if market interest rates have risen since the last auction.

RATINGS AND ASSET COVERAGE RISK

While it is a condition to the issuance of the New Preferred Shares that Moody's assign a rating of aaa and S&P a rating of AAA to the New Preferred Shares, such ratings do not eliminate or necessarily mitigate the risks of investing in New Preferred Shares. Moody's or S&P could downgrade New Preferred Shares, which may make your shares less liquid at an auction or in the secondary market. If Moody's or S&P downgrades the New Preferred Shares, the Trust may alter its portfolio or redeem New Preferred Shares in an effort to improve the rating, although there is no assurance that it will be able to do so to the extent necessary to restore the prior rating. The Trust may voluntarily redeem New Preferred Shares. See "Description of New Preferred Shares-Rating Agency Guidelines and Asset Coverage" for a description of the asset maintenance tests the Trust must meet.

CREDIT RISK

Credit risk refers to an issuer's ability to make timely payments of interest and principal. The Trust may invest in securities rated as low as Baa, MIG or P-1 by Moody's, BBB, SP-2 or A-1 by S&P or BBB or F-1 by Fitch or another nationally recognized statistical rating organization. The Trust may invest up to 20% of its assets in unrated securities that are deemed by the Adviser to be of equivalent credit quality. Adverse changes in economic conditions or changing circumstances are more likely to lead to a weakened capacity of the issuers of such municipal obligations to make timely payments of interest and principal than would be the case with respect to issuers of higher rated municipal obligations.

MUNICIPAL OBLIGATIONS MARKET RISK

Investing in the market for municipal obligations involves certain risks. The amount of public information available about the municipal obligations in the Trust's portfolio is generally less than that for corporate equities or bonds, and the investment performance of the Trust may therefore be more dependent on the analytical abilities of the Adviser than a stock fund or taxable bond fund. The secondary market for municipal obligations also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Trust's ability to sell its portfolio securities at attractive prices.

The ability of municipal issuers to make timely payments of interest and principal may be diminished during general economic downturns and as governmental cost burdens are reallocated among Federal, state and local governments. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations, or on the ability of municipalities to levy taxes. Insurance on municipal obligations held by the Trust may reduce, but will not necessarily eliminate, such risks. Issuers of municipal securities might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, the Trust could experience delays in collecting principal and interest and the Trust may not, in all circumstances, be able to collect all principal and interest to which it is entitled. To enforce its rights in the event of a default in the payment of interest or repayment of principal, or both, the Trust may take possession of and manage the assets securing the issuer's obligations on such securities, which may increase the Trust's operating expenses. Any income derived from the Trust's ownership or operation of such assets may not be tax-exempt.

REINVESTMENT RISK

Reinvestment risk is the risk that income from the Trust's portfolio will decline if and when the Trust invests the proceeds from matured, traded, prepaid or called bonds at lower interest rates. This risk will increase as the Trust approaches its termination date, because the Trust will reinvest such proceeds in municipal obligations with maturities on or about its termination date, and shorter term municipal obligations generally pay lower rates of interest than longer term municipal obligations. A decline in income could affect the Trust's ability to pay dividends on the New Preferred Shares.

INFLATION RISK

Inflation is the reduction in the purchasing power of money resulting from the increase in the price of goods and services. Inflation risk is the risk that the inflation adjusted (or "real") value of an investment in New Preferred Shares or the income from that investment will be worth less in the future. As inflation occurs, the real value of the New Preferred Shares and distributions declines. In an inflationary period, however, it is expected that, through the auction process, dividend rates on the New Preferred Shares would increase, tending to offset this risk.

MANAGEMENT OF THE TRUST

DIRECTORS AND OFFICERS

The board of directors is responsible for the overall management of the Trust, including supervision of the duties performed by the Adviser. There are eight directors of the Trust. Two of the directors are "interested persons" (as defined in the 1940 Act). The names and business addresses of the directors and officers of the Trust and their principal occupations and other affiliations during the past five years are set forth under "Management of the Trust" in the statement of additional information.

INVESTMENT ADVISER

BlackRock Financial Management, Inc. acts as the Trust's investment adviser (the "Adviser"). BlackRock Advisors, Inc. together with its investment advisory subsidiaries, including the Adviser, is a global asset management firm with assets of approximately $148 billion under management as of September 30, 1999. The Adviser has its principal office at 345 Park Avenue, New York, New York 10154. BlackRock Advisors and its subsidiaries constitute the asset management arm of PNC Bank, N.A., and together have over 671 employees. The Adviser and its affiliates provide fixed income, liquidity, equity, alternative investment, and risk management products for clients worldwide. As of September 30, 1999, the Adviser managed approximately $83 billion in various fixed income sectors, including $8 billion in municipal securities. The Adviser and its affiliates manage 13 closed-end, six open-end and six money market municipal funds. In addition, the Adviser manages portfolios of municipal securities for large insurance companies and high net worth individuals.

INVESTMENT PHILOSOPHY

The Adviser's investment decision-making process for the municipal bond sector is subject to the same discipline, oversight and investment philosophy that the firm applies to other sectors of the fixed income market.

The Adviser uses a relative value strategy that evaluates the trade-off between risk and return to seek to achieve the Trust's investment objective. This strategy is combined with disciplined risk control techniques and applied in sector, sub-sector and individual security selection decisions. The Adviser's extensive personnel and technology resources are the key drivers of the investment philosophy.

The Adviser's Municipal Bond Team. The Adviser uses a team approach to managing municipal portfolios. The Adviser believes that this approach offers substantial benefits over one that is dependent on the market wisdom or investment expertise of only a few individuals.

The Adviser's municipal bond team includes three portfolio managers and six credit research analysts. The team is led by Kevin M. Klingert, a managing director and portfolio manager at the Adviser. Mr. Klingert is a senior portfolio manager and head of municipal bonds at the Adviser, a position he has held since joining the Adviser in 1991. Mr. Klingert has over 15 years of experience in the municipal market. Prior to joining the Adviser, Mr. Klingert was an Assistant Vice President in the Unit Investment Trust Department at Merrill Lynch, Pierce, Fenner & Smith, which he joined in 1985. Mr. Klingert has primary responsibility for managing client portfolios with a special emphasis on municipal securities. The portfolio management team also includes Craig Kasap. Mr. Kasap has been a portfolio manager at the Adviser for over two years and is a member of the Adviser's Investment Strategy Group. Prior to joining the Adviser in 1997, Mr. Kasap spent three years as a municipal bond trader with Keystone Investments in Boston where he was involved in formulating the firm's municipal bond investment strategies. James McGinley is also a member of the Adviser's municipal bond portfolio management team and Investment Strategy Group. Prior to joining the Adviser in 1999 as a Vice President, Mr. McGinley worked at Prudential Securities as an Associate Vice President in Municipal Research.

The Adviser's municipal bond portfolio managers are responsible for 25 municipal bond portfolios, valued as of September 30, 1999 at approximately $5.5 billion, plus approximately an additional $2.5 billion in municipal bonds held across portfolios with broader investment mandates. The team is responsible for portfolios with a variety of investment objective and constraints, including national funds and state-specific funds. As of September 30, 1999, the team managed 13 closed-end municipal funds with over $3 billion in assets.

The Adviser's Investment Process. The Adviser has in-depth expertise in the fixed income market. The Adviser applies the same risk-controlled, active sector rotation style (discussed below) to the management process for all of its fixed income portfolios. The Adviser believes that it is unique in its integration of taxable and municipal bond specialists. Both taxable and municipal bond portfolio managers share the same trading floor and interact frequently for determining the firm's overall investment strategy. This interaction allows each portfolio manager to access the combined experience and expertise of the entire portfolio management group at the Adviser.

The Adviser's portfolio management process emphasizes research and analysis of specific sectors and securities, not interest rate speculation. The Adviser believes that market-timing strategies can be highly volatile and potentially produce inconsistent results. Instead, the Adviser thinks that value over the long-term is best achieved through a risk-controlled approach, focusing on sector allocation, security selection and yield curve management (discussed below).

In the municipal market, the Adviser believes one of the most important determinants of value is supply and demand. The Adviser's ability to monitor investor flows and frequency and seasonality of issuance is helpful in anticipating the impact of supply and demand on sectors. The Adviser believes that the breadth and expertise of its municipal bond team allows it to anticipate issuance flows, forecast which sectors are likely to have the most supply and plan its investment strategy accordingly.

The Adviser also believes that over the long-term, intense credit analysis will add value and avoid significant relative performance impairments. The municipal credit team is led by Susan C. Heide, Ph.D who, since December 15, 1998, has been managing director responsible for municipal credit research at the Adviser. Ms. Heide supervises a team of five municipal research analysts who have an average of 10 years of experience in municipal credit research. Between 1993 and December 15, 1998, Ms. Heide served as a director at the Adviser, specializing in the credit analysis of municipal securities.

The Adviser's approach to credit risk incorporates a combination of sector-based top-down macro-analysis of industry sectors to determine relative weightings with an issuer-specific, bottom-up detailed credit analysis of issuers and structures. The sector-based approach focuses on rotating into sectors that are undervalued and exiting sectors when fundamentals or technicals become unattractive. The issuer-specific approach focuses on identifying special opportunities where the market undervalues a credit, and devoting concentrated resources to research the credit and monitor the position. The Adviser's analytic process focuses on anticipating changes in credit trends before market recognition. Credit research is a critical element of the Adviser's municipal process. The Adviser's yield curve management process involves, among other things, an evaluation of the risk/return trade off for bonds having different durations, and selecting bonds believed to present an attractive yield relative to the degree of interest rate risk involved.

THE INVESTMENT ADVISORY AGREEMENT

Pursuant to an Investment Advisory Agreement (the "Advisory Agreement"), the Adviser manages the investment of the Trust's assets and provides such investment research, advice and supervision, in conformity with the Trust's investment objective and policies, as necessary for the operations of the Trust.

The Advisory Agreement provides, among other things, that the Adviser will bear all expenses of its employees and overhead incurred in connection with its duties under the Advisory Agreement, and will pay all directors' fees and salaries of the Trust's directors and officers who are affiliated persons (as such term is defined in the 1940 Act) of the Adviser, except that the board of directors may approve reimbursement for the time spent on Trust operations of personnel who spend substantial time on the operations (other than the provision of investment advice) of the Trust or other investment companies advised by the Adviser. The Advisory Agreement provides that the Trust shall pay to the Adviser for its services a monthly fee at the annual rate of 0.35% of the Trust's average weekly net asset value. The liquidation value of any outstanding preferred shares (including the New Preferred Shares) of the Trust is not taken into account in determining the Trust's average weekly net asset value.

Although the Adviser intends to devote such time and effort to the business of the Trust as is reasonably necessary to perform its duties to the Trust, the services of the Adviser are not exclusive and the Adviser provides similar services to other investment companies and other clients and may engage in other activities.

The Advisory Agreement also provides that, in the absence of willful misfeasance, bad faith, gross negligence or reckless disregard of its obligations thereunder, the Adviser is not liable to the Trust or any of the Trust's stockholders for any act or omission by the Adviser in the supervision or management of its respective investment activities or for any loss sustained by the Trust or the Trust's stockholders and provides for indemnification by the Trust of the Adviser, its partners, officers, employees, agents and control persons for liabilities incurred by them in connection with their services to the Trust, subject to certain limitations and conditions.

The Advisory Agreement will continue in effect, provided that each continuance is specifically approved at least annually by both (i) the vote of a majority of the Trust's board of directors or the vote of a majority of the outstanding voting securities of the Trust (as such term is defined in the 1940 Act) and (ii) by the vote of a majority of the directors who are not parties to such Agreement or interested persons (as such term is defined in the 1940 Act) of any such party, cast in person at a meeting called for the purpose of voting on such approval. The Advisory Agreement may be terminated as a whole at any time by the Trust, without the payment of any penalty, upon the vote of a majority of the Trust's board of directors or a majority of the outstanding voting securities of the Trust or by the Adviser, on 60 days' written notice by either party to the other. Except as otherwise provided by order of the SEC or any rule or provision of the 1940 Act, the Agreement will terminate automatically in the event of its assignment (as such term is defined in the 1940 Act and the rules thereunder).

THE ADMINISTRATION AGREEMENT

Princeton Administrators, L.P. (the "Administrator"), 800 Scudders Mill Road, Plainsboro, New Jersey 08536, acts as administrator for the Trust. [The Administrator is an affiliate of _________________________, one of the underwriters of this offering.] Under the Administration Agreement with the Trust (the "Administration Agreement"), the Administrator administers the Trust's corporate affairs subject to the supervision of the Trust's board of directors and in connection therewith furnishes the Trust with office facilities together with such ordinary clerical and bookkeeping services (e.g., preparation of annual and other reports to stockholders and the SEC and filing of Federal, state and local income tax returns) as are not being furnished by the custodian. In connection with its administration of the corporate affairs of the Trust, the Administrator will bear the following expenses:

o the salaries and expenses of all personnel of the Administrator; and

o all expenses incurred by the Administrator in connection with administering the ordinary course of the Trust's business, other than those assumed by the Trust, as described below.

The Administration Agreement provides that the Trust shall pay to the Administrator a monthly fee for its services and the facilities furnished by the Administrator at the annual rate of 0.10% of the Trust's average weekly net asset value. The liquidation value of any outstanding preferred shares (including the New Preferred Shares) of the Trust is not taken into account in determining the Trust's average weekly net asset value.

The Administration Agreement is terminable on 60 days' prior written notice by either party to the other.

EXPENSES OF THE TRUST

Except as indicated above, the Trust will pay all of its expenses, including fees of the directors not affiliated with the Adviser and board meeting expenses: fees of the Adviser and the Administrator; interest charges; taxes; organization expenses; charges and expenses of the Trust's legal counsel and independent accountants, and of the transfer agent, registrar and dividend disbursing agent of the Trust; expenses of repurchasing shares; expenses of issuing any preferred shares (including the New Preferred Shares) or indebtedness; expenses of printing and mailing share certificates, stockholder reports, notices, proxy statements and reports to governmental offices; brokerage and other expenses connected with the execution, recording and settlement of portfolio security transactions; expenses connected with negotiating, effecting purchase or sale, or registering privately issued portfolio securities; custodial fees and expenses for all services to the Trust, including safekeeping of funds and securities and maintaining required books and accounts; expenses of calculating and publishing the net asset value of the Trust's shares; expenses of membership in investment company associations; expenses of fidelity bonding and other insurance expenses including insurance premiums; expenses of stockholders meetings; SEC and state registration fees; New York Stock Exchange listing fees; and fees payable to the National Association of Securities Dealers, Inc. in connection with this offering and fees of any rating agencies retained to rate any preferred shares (including the New Preferred Shares) issued by the Trust.

DESCRIPTION OF PREFERRED SHARES

Certain of the capitalized terms used herein are defined in the Articles Supplementary and Articles of Amendment of the Trust attached as Appendices B-1, B-2 and B-3 to the statement of additional information.

The Preferred Shares of each series are shares of preferred stock of the Trust that entitle their holders to receive dividends when, as and if declared by the board of directors, out of funds legally available therefor, at a rate per annum that may vary for the successive Dividend Periods for each such series. In general, the Applicable Rate for a particular Dividend Period for a particular series of Preferred Shares will be determined by an Auction conducted on the day before the start of such Dividend Period. Existing Holders and Potential Holders of Preferred Shares may participate in Auctions therefor, although Existing Holders desiring to continue to hold all of their Preferred Shares regardless of the Applicable Rate resulting from Auctions need not participate. For an explanation of Auctions and the method of determining the Applicable Rate, see "The Auction".

A Dividend Payment Date and an Auction Date for the Trust's outstanding Series T28 Preferred Shares may coincide with a Dividend Payment Date and an Auction Date for the Series T7 Preferred Shares (including the New Preferred Shares); however, the Series T28 Preferred Shares will have a Dividend Period of 28 days in length and the Series T7 Preferred Shares (including the New Preferred Shares) will have a Dividend Period of seven days in length (except in the case of the Initial Dividend Period or a Special Dividend Period in respect of either series).

The Preferred Shares have a liquidation preference of $25,000 per share plus an amount equal to accumulated but unpaid dividends (whether or not carried or declared) plus the premium, if any, resulting from the designation of a Premium Call Period and are fully paid and non-assessable. The Preferred Shares are not convertible into common shares or other capital stock of the Trust and the holders thereof have no preemptive rights. The Preferred Shares will not be subject to any sinking fund but will be subject to redemption at the option of the Trust on any Dividend Payment Date with respect thereto (provided that no Preferred Shares shall be subject to optional redemption during a Non-Call Period) and, in certain circumstances, are subject to mandatory redemption by the Trust. Except with regard to their respective Initial Dividend Periods and Initial Dividend Rates and except for the timing of their respective Auction Dates and Dividend Payment Dates, the rights and preferences of each series of Preferred Shares are the same.

In connection with the auction procedures described below, Deutsche Bank Group is the Auction Agent, the transfer agent, registrar, dividend disbursing agent and redemption agent for the Preferred Shares.

DESCRIPTION OF NEW PREFERRED SHARES

The following is a brief description of the terms of the New Preferred Shares. For the complete terms of the New Preferred Shares, including definitions of terms used but not defined, please refer to the detailed description of the New Preferred Shares in the Articles Supplementary and Articles of Amendment attached as Appendices B-1, B-2 and B-3 to the statement of additional information. We refer to the Articles Supplementary and Articles of Amendment in this prospectus collectively as the "Articles Supplementary."

GENERAL

The Trust is authorized to issue 200 million shares of capital stock, $.01 par value. The board of directors of the Trust is authorized to classify and reclassify any unissued shares of capital stock from time to time by setting or changing the preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications or terms or conditions of redemption of such shares of stock. In connection with the offerings of New Preferred Shares described herein, the board of directors has reclassified 662 shares of unissued capital stock as New Preferred Shares.

The New Preferred Shares will rank on parity with the currently outstanding Preferred Shares of the Trust as to the payment of dividends and the distribution of assets upon liquidation. Each New Preferred Share carries one vote on matters that New Preferred Shares can be voted. New Preferred Shares, when issued, will be fully paid and non- assessable and have no preemptive, conversion or cumulative voting rights.

DIVIDENDS AND DIVIDEND PERIODS

General. The following is a general description of dividends and Dividend Periods. The Initial Dividend Period for the New Preferred Shares will be ___ days and the dividend rate for this period will be __%. Subsequent Dividend Periods generally will be seven days and the dividend rates for those periods will be determined by auction. The Trust, subject to certain conditions, may change the length of subsequent Dividend Periods by designating them as Special Dividend Periods. See "--Designation of Special Dividend Periods" below.

Dividend Payment Dates. Dividends on New Preferred Shares will be payable, when, as and if declared by the board of directors, out of legally available funds in accordance with the Trust's charter and applicable law, on _____________, 2000, and thereafter generally on each Wednesday. However, if dividends are payable on a Wednesday that is not a Business Day, then dividends will generally be payable on the next day, if such day is a Business Day, or as otherwise specified in the Trust's charter. With respect to a Special Dividend Period of 35 days or fewer, dividends on New Preferred Shares are ordinarily paid on the next Business Day next succeeding the last day thereof. With respect to a Special Dividend Period of more than 35 days, dividends on New Preferred Shares are ordinarily paid on the first business day of each calendar month during such Special Dividend Period and on the Business Day next succeeding the last day thereof.

Dividends will be paid through the Securities Depository on each Dividend Payment Date. The Securities Depository, in accordance with its current procedures, is expected to distribute dividends received from the Auction Agent in same-day funds on each Dividend Payment Date to Agent Members. These Agent Members are in turn expected to distribute such dividends to the persons for whom they are acting as agents. However, each of the current Broker-Dealers has indicated to the Trust that dividend payments will be available in same-day funds on each Dividend Payment Date to customers that use such Broker-Dealer or that Broker-Dealer's designee as Agent Member.

Calculation of Dividend Payment. The Trust computes the dividend per New Preferred Share by multiplying the Applicable Rate in effect by a fraction. The numerator of this fraction will normally be seven (i.e. the number of days in the Dividend Period) and the denominator will normally be
365. If the Trust has designated a Special Dividend Period of 365 days or more, then the numerator will be the number of days in the Dividend Period, and the denominator will be 360. In either case, this rate is then multiplied by $25,000 to arrive at dividends per share.

Dividends on New Preferred Shares will accumulate from the date of their original issue. For each Dividend Payment Period after the Initial Dividend Period, the dividend rate will be the dividend rate determined at the Auction, except as provided below. The dividend rate that results from an Auction for New Preferred Shares will not be greater than the Maximum Applicable Rate. In the case of a Special Dividend Period for which Bid Requirements are specified, the dividend rate will not be less than the Minimum Applicable Rate specified in the Notice of Special Dividend Period. During Dividend Periods for which no Bid Requirements are specified, there will be no Minimum Applicable Rate.

The Maximum Applicable Rate for any regular Dividend Payment Period will be the Applicable Percentage of the higher of the 30-day "AA" Composite Commercial Paper Rate and the Taxable Equivalent of the Short-Term Municipal Bond Rate. In the case of a Special Dividend Period, the Maximum Applicable Rate for any Dividend Payment Period included in such Special Dividend Period will be the Applicable Percentage (determined on the date of the Notice of Special Dividend Period in the case of any such Notice that specifies a Maximum Applicable Rate applicable to such Special Dividend Payment Period) of the Special Dividend Period Reference Rate for such Dividend Payment Period. The Applicable Percentage will be determined based on (i) the lower of the credit rating or ratings assigned on such date to such shares by Moody's and S&P (or if Moody's or S&P or both shall not make such rating available, the equivalent of either or both of such ratings by a Substitute Rating Agency or two Substitute Rating Agencies or, in the event that only one such rating shall be available, such rating) and (ii) whether the Trust has provided notification to the Auction Agent prior to the Auction establishing the Applicable Rate for any dividend period that net capital gains or other taxable income will be included in such dividend on New Preferred Shares as follows:

             Credit Ratings                  Applicable       Applicable
             --------------                  Percentage:      Percentage:
     Moody's                  S&P         No Notification   Notification
     -------                  ---         ---------------   ------------
 "aa3" or higher         AA- or higher        110%               150%
  "a3" to "al"             A- to A+           125%               160%
"baa3" to "baal"         BBB- to BBB+         150%               250%
 "ba3" to "bal"           BB- to BB+          200%               275%

Below "ba3" Below BB- 250% 300%

Prior to each Dividend Payment Date, the Trust is required to deposit with the Auction Agent sufficient funds for the payment of declared dividends. The failure to make such deposit will not result in the cancellation of any Auction. The Trust does not intend to establish any reserves for the payment of dividends.

Additional Dividends. If, in the case of a Dividend Period of 28 days or fewer, the Trust retroactively allocates any net capital gain or other taxable income to a dividend paid on New Preferred Shares and did not give advance notice thereof to the Auction Agent as described below under "The Auction-Auction Procedures" (the amount of the retroactive allocation referred to herein as a "Retroactive Taxable Allocation") solely by reason of the fact that the retroactive allocation is made as a result of the redemption of all or a portion of the outstanding New Preferred Shares or the liquidation of the Trust, the Trust will, within 90 days (and generally within 60 days) after the end of the Trust's fiscal year for which a Retroactive Taxable Allocation is made, provide notice thereof to the Auction Agent and to each holder of New Preferred Shares (initially expected to be Cede & Co. as nominee of the Securities Depository) during such fiscal year at the holder's address listed on the stock books of the Trust. The Trust will, within 30 days after such notice is given to the Auction Agent, pay to the Auction Agent (who will then distribute to such holders of New Preferred Shares), out of funds legally available therefor, an amount equal to the aggregate Additional Dividend (as defined below) with respect to all Retroactive Taxable Allocations made to such holders during the fiscal year in question. See "Taxes".

If, in the case of a Dividend Period of 35 days or more, the Trust makes a Retroactive Taxable Allocation to a dividend paid on New Preferred Shares, the Trust will, within 90 days (and generally within 60 days) after the end of the Trust's fiscal year for which a Retroactive Taxable Allocation is made, provide notice thereof to the Auction Agent and to each holder of New Preferred Shares (initially expected to be Cede & Co., as nominee of the Securities Depository) during such fiscal year at the holder's address list on the stock books of the Trust. The Trust will, within 30 days after such notice is given to the Auction Agent, pay to the Auction Agent (who will then distribute to such holders of New Preferred Shares), out of funds legally available therefor, an amount equal to the aggregate Additional Dividend (as defined below) with respect to all Retroactive Taxable Allocations made to such holders during the fiscal year in question. See "Taxes".

In no other instance will the Trust be required to make payments to holders of New Preferred Shares to offset the tax effect of any reallocation of net capital gain or other taxable income.

An "Additional Dividend" means an amount paid to a holder of New Preferred Shares that, when taken together with the aggregate amount of Retroactive Taxable Allocations allocated to such holder with respect to the fiscal year in question, would cause the holder's dividends from the aggregate of both the Retroactive Taxable Allocations and the Additional Dividend to be equal to the amount of the dividends that would have been received and retained by the holder if the Retroactive Taxable Allocations had not been made. Additional Dividends shall be calculated:

o without consideration being given to the time value of money;

o assuming that no holder of New Preferred Shares is subject to AMT with respect to dividends received from the Trust; and

o assuming that each Retroactive Taxable Allocation would be taxable in the hands of each holder of New Preferred Shares at the maximum marginal regular Federal income tax rate applicable to individuals or corporations, whichever is greater, in effect at the end of the fiscal year in question.

Although the Trust generally intends to designate any Additional Dividend as an exempt-interest dividend to the extent permitted by applicable law, it is possible that all or a portion of any Additional Dividend will be taxable to the recipient thereof. See "Taxes." The Trust will not pay a further Additional Dividend with respect to any taxable portion of an Additional Dividend.

Restrictions on Dividends and Other Distributions. Except as otherwise described herein, when the Trust has any preferred shares outstanding, including the New Preferred Shares, the Trust may not declare, pay or set apart for payment, any dividend or other distribution (other than a dividend or distribution paid in, or in options, warrants or rights to subscribe for or purchase, its common shares) in respect of common shares. In addition, the Trust may not call for redemption, redeem, purchase or otherwise acquire for consideration any common shares (except by conversion into or exchange for shares of the Trust ranking junior to the New Preferred Shares as to the payment of dividends and the distribution of assets upon liquidation). However, the Trust is not confined by the above restrictions if:

o immediately after such transaction, the Discounted Value of the Trust's portfolio would be equal to or greater than the Preferred Shares Basic Maintenance Amount and the 1940 Act Preferred Shares Asset Coverage (see "--Rating Agency Guidelines and Asset Coverage" below),

o full cumulative dividends on the New Preferred Shares due on or prior to the date of the transaction have been declared and paid or shall have been declared and sufficient funds for the payment thereof deposited with the Auction Agent;

o any Additional Dividend required to be paid on or before the date of such declaration or payment has been paid; and

o the Trust has redeemed the full number of New Preferred Shares required to be redeemed by any provision for mandatory redemption contained in the Articles Supplementary.

Except as set forth in the next sentence, the Trust will not declare, pay or set apart for payment any dividend on any shares of the Trust ranking, as to the payment of dividends, on a parity with New Preferred Shares for any period unless the Trust has declared and paid or contemporaneously declares and pays full cumulative dividends on the New Preferred Shares through its most recent Dividend Payment Date. However, when the Trust has not paid dividends in full on the New Preferred Shares through the most recent Dividend Payment Date or upon any shares of the Trust ranking, as to the payment of dividends, on a parity with New Preferred Shares through their most recent respective Dividend Payment Dates, the Trust will declare all dividends upon New Preferred Shares and any shares of the Trust ranking, as to the payment of dividends, on a parity with New Preferred Shares, pro rata so that the amount of dividends declared per share on New Preferred Shares and such other class or series of shares will in all cases bear to each other the same ratio that accumulated dividends per share on the New Preferred Shares and such other class or series of shares bear to each other.

Designation of Special Dividend Periods. The Trust may, at its sole option and whenever permitted by law, declare a Special Dividend Period. To declare a Special Dividend Period, the Trust will give notice (a "Request for Special Dividend Period") to the Auction Agent and to each Broker-Dealer and request that the next succeeding Dividend Period for such series of New Preferred Shares be a number of days (other than seven) evenly divisible by seven and specified in such notice. For any Auction occurring after the initial Auction, the Trust may not give a Request for Special Dividend Period unless Sufficient Clearing Bids were made in the last occurring Auction and unless full cumulative dividends, any amounts due with respect to mandatory redemptions, and any Additional Dividends payable prior to such date have been paid in full. The Trust must have also received confirmation from Moody's and S&P or any Substitute Rating Agency that the proposed Special Dividend Period will not adversely affect such agency's then-current rating on the New Preferred Shares. A Request for Special Dividend Period will also specify any proposed Bid Requirements. Upon receiving a Request for Special Dividend Period, the Broker-Dealer(s) will jointly determine whether, given the factors set forth in the Articles Supplementary, it is advisable that the Trust issue a Notice of Special Dividend Period for the New Preferred Shares as contemplated by the Request for Special Dividend Period and, if advisable, the Specific Redemption Provisions and will give the Trust and the Auction Agent notice of its determination. If no Broker-Dealer objects to the Notice of Special Dividend Period, the Trust may issue such notice specifying the duration of the Special Dividend Period, the Bid Requirements, if any, and the Specific Redemption Provisions, if any.

REDEMPTION

Mandatory Redemption. If the Trust does not timely cure a failure to maintain (a) a Discounted Value of its portfolio equal to the Preferred Shares Basic Maintenance Amount or (b) the 1940 Act Preferred Shares Asset Coverage, in accordance with the requirements of the rating agencies that rate the New Preferred Shares, the Trust must redeem all or a portion of the New Preferred Shares. This mandatory redemption will take place on a date that the board of directors specifies out of legally available funds in accordance with the Trust's charter and applicable law, at the redemption price of $25,000 per share plus accumulated but unpaid dividends (whether or not earned or declared) to the date fixed for redemption. The mandatory redemption will be limited to the number of New Preferred Shares necessary to restore the required Discounted Value or the 1940 Act Preferred Shares Asset Coverage, as the case may be.

Optional Redemption. To the extent permitted under the 1940 Act and Maryland law, upon giving a Notice of Redemption, as provided below, the Trust, at its option, may redeem the New Preferred Shares, in whole or in part, out of funds legally available therefor, on any Dividend Payment Date at the optional redemption price per share of $25,000 per share plus an amount equal to accumulated but unpaid dividends (whether or not earned or declared) to the date fixed for redemption plus the premium, if any, resulting from the designation of a Premium Call Period; provided that no New Preferred Shares shall be subject to optional redemption during a Non-Call Period. In addition, holders of New Preferred Shares may be entitled to receive Additional Dividends in the event of redemption of such New Preferred Shares to the extent provided herein. The Trust has the authority to redeem the New Preferred Shares for any reason and may redeem all or part of then-outstanding New Preferred Shares if it anticipates that the Trust's leveraged capital structure will result in a lower rate of return to holders of common shares of the Trust for any significant period of time than that obtainable if such common shares were not leveraged.

LIQUIDATION

Upon a voluntary or involuntary liquidation of the Trust, the holders of outstanding New Preferred Shares will receive, from the assets of the Trust available for distribution to its shareholders, the liquidation preference plus all accumulated but unpaid dividends (whether or not earned or declared) plus the premium, if any, resulting from the designation of a Premium Call Period and any applicable Additional Dividends before any payment is made to the common shares. The holders of outstanding New Preferred Shares will be entitled to receive these amounts subject to the rights of holders of any series or class of shares, including other series of Preferred Shares, ranking on a parity with the New Preferred Shares with respect to the distribution of assets upon liquidation of the Trust. After the payment to the holders of New Preferred Shares of the full preferential amounts provided for as described, the holders of New Preferred Shares will have no right or claim to any of the remaining assets of the Trust.

Neither the sale of all or substantially all the property or business of the Trust, nor the merger or consolidation of the Trust into or with any other corporation, nor the merger or consolidation of any other corporation into or with the Trust, is a voluntary or involuntary liquidation for the purposes of the foregoing paragraph.

RATING AGENCY GUIDELINES AND ASSET COVERAGE

The Trust is required under guidelines of Moody's and S&P to maintain assets having in the aggregate a Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount. Moody's and S&P have each established separate guidelines for calculating Discounted Value. To the extent any particular portfolio holding does not satisfy a rating agency's guidelines, all or a portion of the holding's value will not be included in the rating agency's calculation of Discounted Value. The Moody's and S&P guidelines do not impose any limitations on the percentage of the Trust's assets that may be invested in holdings not eligible for inclusion in the calculation of the Discounted Value of the Trust's portfolio. The amount of such assets included in the portfolio at any time may vary depending upon the rating, diversification and other characteristics of the eligible assets included in the portfolio. The Preferred Shares Basic Maintenance Amount includes the sum of (a) the aggregate liquidation preference of New Preferred Shares then outstanding and (b) certain accrued and projected payment obligations of the Trust.

The Trust is also required under rating agency guidelines to maintain, with respect to New Preferred Shares, as of the last Business Day of each month in which any such shares are outstanding, asset coverage of at least 200% with respect to senior securities which are equity shares, including the New Preferred Shares (or such other asset coverage as may in the future be specified in or under the 1940 Act as the minimum asset coverage for senior securities which are equity shares of a closed-end investment company as a condition of declaring dividends on its common shares) ("1940 Act Preferred Shares Asset Coverage"). Based on the composition of the portfolio of the Trust and market conditions as of __________ ___, 2000, the 1940 Act Preferred Shares Asset Coverage with respect to all of the Trust's preferred shares, assuming the issuance on that date of all New Preferred Shares offered hereby and giving effect to the deduction of related sales load and related offering costs estimated at $465,500, would have been computed as follows:

  Value of Trust assets less liabilities
    not constituting senior securities         =  $        =   %
    ----------------------------------            -------
Senior securities representing indebtedness       $
                   plus
 liquidation value of the preferred shares

In the event the Trust does not timely cure a failure to maintain
(a) a Discounted Value of its portfolio equal to the Preferred Shares Basic Maintenance Amount or (b) the 1940 Act Preferred Shares Asset Coverage, in each case in accordance with the requirements of the rating agency or agencies then rating the New Preferred Shares, the Trust will be required to redeem New Preferred Shares as described under "--Redemption--Mandatory Redemption" above.

Pursuant to S&P guidelines, for so long as the New Preferred Shares are rated by S&P, the Trust will also be required under the Articles Supplementary to have, as of each Valuation Date, Deposit Securities with maturity or tender payment dates not later than the Dividend Payment Date (collectively, "Dividend Coverage Assets") for each share of New Preferred Shares outstanding that follows such Valuation Date and having in the aggregate a value not less than the Dividend Coverage Amount (the "Minimum Liquidity Level"). The "Dividend Coverage Amount", as of any Valuation Date, means (A) the aggregate amount of cash dividends that will accumulate on outstanding New Preferred Shares to (but not including) the next Dividend Payment Date that follows such Valuation Date less (B) the combined fair market value of Deposit Securities irrevocably deposited for the payment of cash dividends on New Preferred Shares. "Deposit Securities" means cash, the book value of municipal obligations sold for which payment is due within five Business Days and before the next Valuation Date and municipal obligations rated at least A-1 + or SP- I + by S&P, VMIG-1 or MIG-1 by Moody's. The definitions of "Deposit Securities", "Dividend Coverage Assets" and "Dividend Coverage Amount" may be changed from time to time by the Trust without shareholder approval, but only in the event the Trust receives confirmation from S&P that any such change would not impair the ratings then assigned by S&P to New Preferred Shares.

The Trust may, but is not required to, adopt any modifications to the guidelines that may be established by Moody's or S&P. Failure to adopt any such modifications, however, may result in a change in the ratings described above or a withdrawal of ratings altogether. In addition, any rating agency providing a rating for the New Preferred Shares may, at any time, change or withdraw any such rating. The Board may, without shareholder approval, amend, alter or repeal any or all of the definitions and related provisions which have been adopted by the Trust pursuant to the rating agency guidelines in the event the Trust receives written confirmation from Moody's or S&P, as the case may be, that any such amendment, alteration or repeal would not impair the rating then assigned to the New Preferred Shares.

As recently described by Moody's and S&P, a preferred stock rating is an assessment of the capacity and willingness of an issuer to pay preferred stock obligations. The rating on the New Preferred Shares is not a recommendation to purchase, hold or sell those shares, inasmuch as the rating does not comment as to market price or suitability for a particular investor. The rating agency guidelines described above also do not address the likelihood that an owner of New Preferred Shares will be able to sell such shares in an Auction or otherwise. The ratings are based on current information furnished to Moody's and S&P by the Trust and the Adviser and information obtained from other sources. The ratings may be changed, suspended or withdrawn as a result of changes in, or the unavailability of, such information. The common shares have not been rated by a nationally recognized statistical rating organization.

A rating agency's guidelines will apply to New Preferred Shares only so long as the rating agency is rating the shares. The Trust will pay certain fees to Moody's and S&P for rating the New Preferred Shares.

VOTING RIGHTS

Except as otherwise provided in this prospectus and in the statement of additional information or as otherwise required by law, holders of New Preferred Shares will have equal voting rights with holders of common shares and any other preferred shares of the Trust (one vote per share) and will vote together with holders of common shares and any other preferred shares as a single class.

In connection with the election of the Trust's directors, holders of outstanding preferred shares of the Trust, including New Preferred Shares, voting as a separate class, are entitled to elect two of the Trust's directors, and the remaining directors are elected by holders of common shares and preferred shares, including New Preferred Shares, voting together as a single class. In addition, if at any time dividends (whether or not earned or declared) on outstanding preferred shares of the Trust, including New Preferred Shares, are due and unpaid in an amount equal to two full years of dividends, and sufficient cash or specified securities have not been deposited with the Auction Agent for the payment of such dividends, then, the sole remedy of holders of outstanding preferred shares of the Trust, including New Preferred Shares, is that the number of directors constituting the board of directors will be automatically increased by the smallest number that, when added to the two directors elected exclusively by the holders of preferred shares of the Trust, including New Preferred Shares, as described above, would constitute a majority of the board of directors. The holders of preferred shares of the Trust, including New Preferred Shares, will be entitled to elect that smallest number of additional directors at a special meeting of shareholders held as soon as possible and at all subsequent meetings at which directors are to be elected. The terms of office of the persons who are directors at the time of that election will continue. If the Trust thereafter shall pay, or declare and set apart for payment, in full, all dividends payable on all outstanding preferred shares of the Trust, including New Preferred Shares, the special voting rights stated above will cease, and the terms of office of the additional directors elected by the holders of the preferred shares will automatically terminate.

As long as any preferred shares of the Trust are outstanding, the Trust will not, without the affirmative vote or consent of the holders of at least a majority of the Preferred Shares (including New Preferred Shares) outstanding at the time (voting as a separate class):

(a) authorize, create or issue, or increase the authorized or issued amount of, any class or series of stock ranking prior to or on a parity with the Preferred Shares (including the New Preferred Shares) with respect to payment of dividends or the distribution of assets on liquidation, or increase the authorized amount of the Preferred Shares (including the New Preferred Shares) or any other preferred stock, unless the Trust obtains written confirmation from Moody's (if Moody's is then rating preferred shares), S&P (if S&P is then rating preferred shares) or any Substitute Rating Agency (if any such Substitute Rating Agency is then rating preferred shares) that the issuance of such class or series would not impair the rating then assigned by such rating agency to the Preferred Shares) and the Trust continues to comply with Section 13 of the 1940 Act, the 1940 Act Preferred Shares Asset Coverage requirements and the Preferred Shares Basic Maintenance Amount requirements, in which case the vote or consent of the holders of the Preferred Shares (including the New Preferred Shares) is not required;

(b) amend, alter or repeal the provisions of the Trust's charter whether by merger, consolidation or otherwise, so as to adversely affect any of the contract rights expressly set forth in the Trust's charter of holders of Preferred Shares (including the New Preferred Shares) or any other preferred stock;

(c) authorize the Trust's conversion from a closed-end to an open-end investment company; or

(d) amend the provisions of the Trust's charter which provide for the classification of the board of directors of the Trust into three classes, each with a term of office of three years with only one class of directors standing for election in any year (presently Article VI of the Trust's charter).

To the extent permitted under the 1940 Act, the Trust shall not approve any of the actions set forth in (a) or (b) above which adversely affects the rights expressly set forth in the Trust's charter of a holder of shares of a series of preferred shares differently than those of a holder of shares of any other series of preferred shares without the affirmative vote of the holders of at least a majority of the shares of each series adversely affected and outstanding at such time, in person or by proxy, at a meeting (each such adversely affected series voting separately as a class) or by the unanimous written consent of the holders of all outstanding preferred shares. Unless a higher percentage is provided for under the Trust's charter, the affirmative vote of the holders of a majority of the outstanding preferred shares, including New Preferred Shares, voting together as a single class, will be required to approve any plan of reorganization (including bankruptcy proceedings) adversely affecting such shares or any action requiring a vote of security holders under Section 13(a) of the 1940 Act. Notwithstanding the preceding sentence, to the extent permitted by Maryland General Corporation Law, no vote of holders of common stock, either separately or together with holders of preferred shares as a single class, is necessary to take the actions contemplated by (a) and (b) above and the holders of common shares will not be entitled to vote in respect of such matters, unless, in the case of the actions contemplated by (b) above, the action would adversely affect the contract rights expressly set forth in the charter of the holders of common shares.

The foregoing voting provisions will not apply with respect to New Preferred Shares if, at or prior to the time when a vote is required, such shares have been (i) redeemed or (ii) called for redemption and sufficient funds have been deposited in trust to effect such redemption.

THE AUCTION

GENERAL

The Trust's charter provides that, except as otherwise described herein, the Applicable Rate for the New Preferred Shares for each Dividend Period after the Initial Dividend Period shall be equal to the rate per annum that the Auction Agent advises has resulted on the Business Day preceding the first day of such subsequent Dividend Period (an "Auction Date") from implementation of the auction procedures (the "Auction Procedures") set forth in the Trust's charter and summarized below, in which persons determine to hold or offer to sell or, based on dividend rates bid by them, offer to purchase or sell New Preferred Shares. Each periodic implementation of the Auction Procedures is referred to herein as an "Auction." See the Articles Supplementary for a more complete description of the Auction process.

Auction Agency Agreement. The Trust will enter into an Auction Agency Agreement (the "Auction Agency Agreement") with the Auction Agent (currently, Deutsche Bank Group) which provides, among other things, that the Auction Agent will follow the Auction Procedures to determine the Applicable Rate for New Preferred Shares so long as the Applicable Rate for New Preferred Shares is to be based on the results of an Auction.

The Auction Agent may terminate the Auction Agency Agreement upon notice to the Trust no earlier than [60] days after such notice. If the Auction Agent should resign, the Trust will use its best efforts to enter into an agreement with a successor Auction Agent containing substantially the same terms and conditions as the Auction Agency Agreement. The Trust may remove the Auction Agent provided that prior to such removal the Trust has entered into such an agreement with a successor Auction Agent.

Broker-Dealer Agreements. Each Auction requires the participation of one or more Broker-Dealers. The Auction Agent will enter into agreements (collectively, the "Broker-Dealer Agreements") with several Broker-Dealers selected by the Trust, which provide for the participation of those Broker-Dealers in Auctions for New Preferred Shares.

The Auction Agent after each Auction for New Preferred Shares will pay to each Broker-Dealer, from funds provided by the Trust, a service charge at the annual rate of 1/4 of 1% in the case of any Auction immediately preceding a Dividend Period of less than one year, or a percentage agreed to by the Trust and the Broker-Dealers in the case of any Auction immediately preceding a Dividend Period of one year or longer, of the purchase price of New Preferred Shares placed by such Broker-Dealer at such Auction. For the purposes of the preceding sentence, New Preferred Shares will be placed by a Broker-Dealer if such shares were (a) the subject of Hold Orders deemed to have been submitted to the Auction Agent by the Broker-Dealer and were acquired by such Broker-Dealer for its own account or were acquired by such Broker-Dealer for its customers who are Beneficial Owners or (b) the subject of an Order submitted by such Broker- Dealer that is (i) a Submitted Bid of an Existing Holder that resulted in such Existing Holder continuing to hold such shares as a result of the Auction or (ii) a Submitted Bid of a Potential Holder that resulted in such Potential Holder purchasing such shares as a result of the Auction or (iii) a valid Hold Order.

The Trust may request the Auction Agent to terminate one or more Broker-Dealer Agreements at any time, provided that at least one Broker-Dealer Agreement is in effect after such termination.

AUCTION PROCEDURES

Prior to the Submission Deadline on each Auction Date for the New Preferred Shares, each customer of a Broker- Dealer who is listed on the records of that Broker-Dealer (or, if applicable, the Auction Agent) as a holder of New Preferred Shares (a "Beneficial Owner") may submit orders ("Orders") with respect to New Preferred Shares to that Broker-Dealer as follows:

1. Hold Order--indicating its desire to hold New Preferred Shares without regard to the Applicable Rate for the next Dividend Period thereof.

2. Bid--indicating its desire to sell New Preferred Shares at $25,000 per share if the Applicable Rate for shares of such series for the next Dividend Period thereof is less than the rate or spread specified in such Bid.

3. Sell Order--indicating its desire to sell New Preferred Shares at $25,000 per share without regard to the Applicable Rate for shares of such series for the next Dividend Period thereof.

A Beneficial Owner may submit different types of Orders to its Broker-Dealer with respect to New Preferred Shares then held by such Beneficial Owner. A Beneficial Owner that submits a Bid to its Broker-Dealer having a rate higher than the Maximum Applicable Rate on the Auction Date therefor will be treated as having submitted a Sell Order to its Broker-Dealer. A Beneficial Owner that fails to submit an Order to its Broker-Dealer will be deemed to have submitted a Hold Order to its Broker-Dealer; provided however, that if a Beneficial Owner fails to submit an Order to its Broker-Dealer for an Auction relating to a Dividend Period of more than 91 days, such Beneficial Owner will be deemed to have submitted a Sell Order to its Broker-Dealer. A Sell Order shall constitute an irrevocable offer to sell the New Preferred Shares subject thereto. A Beneficial Owner that offers to become the Beneficial Owner of additional New Preferred Shares is, for purposes of such offer, a Potential Beneficial Owner as discussed below.

A customer of a Broker-Dealer that is not a Beneficial Owner of New Preferred Shares but that wishes to purchase New Preferred Shares, or that is a Beneficial Owner that wishes to purchase additional New Preferred Shares (in each case, a "Potential Beneficial Owner"), may submit Bids to its Broker-Dealer in which it offers to purchase New Preferred Shares at $25,000 per share if the Applicable Rate for the next Dividend Period thereof is not less than the rate specified in such Bid. A Bid placed by a Potential Beneficial Owner specifying a rate higher than the Maximum Applicable Rate on the Auction Date therefor will not be accepted.

Any Bid by an Existing Holder that specifies a Spread with respect to an Auction in which a Spread is not included in any Bid Requirements or in which there are no Bid Requirements and an Order that does not specify a Spread with respect to an Auction in which a Spread is included in any Bid Requirements shall be treated as a Sell Order.

The Broker-Dealers in turn will submit the Orders of their respective customers who are Beneficial Owners and Potential Beneficial Owners to the Auction Agent, designating themselves (unless otherwise permitted by the Trust) as Existing Holders in respect of shares subject to Orders submitted or deemed submitted to them by Beneficial Owners and as Potential Holders in respect of shares subject to Orders submitted to them by Potential Beneficial Owners. However, neither the Trust nor the Auction Agent will be responsible for a Broker-Dealer's failure to comply with the foregoing. Any Order placed with the Auction Agent by a Broker-Dealer as or on behalf of an Existing Holder or a Potential Holder will be treated in the same manner as an Order placed with a Broker-Dealer by a Beneficial Owner or Potential Beneficial Owner. Similarly, any failure by a Broker-Dealer to submit to the Auction Agent an Order in respect of any New Preferred Shares held by it or customers who are Beneficial Owners will be treated in the same manner as a Beneficial Owner's failure to submit to its Broker-Dealer an Order in respect of New Preferred Shares held by it. A Broker- Dealer may also submit Orders to the Auction Agent for its own account as an Existing Holder or Potential Holder, provided it is not an affiliate of the Trust.

If Sufficient Clearing Bids for New Preferred Shares exist (that is, the number of shares subject to Bids submitted or deemed submitted to the Auction Agent by Broker-Dealers as or on behalf of Potential Holders with rates or spreads equal to or lower than the Maximum Applicable Rate is at least equal to the number of New Preferred Shares subject to Sell Orders submitted or deemed submitted to the Auction Agent by Broker-Dealers as or on behalf of Existing Holders), the Applicable Rate for New Preferred Shares for the next succeeding Dividend Period thereof will be the lowest rate specified in the Submitted Bids which, taking into account such rate and all lower rates bid by Broker-Dealers as or on behalf of Existing Holders and Potential Holders, would result in Existing Holders and Potential Holders owning the New Preferred Shares available for purchase in the Auction. If Sufficient Clearing Bids for New Preferred Shares do not exist, the Applicable Rate for the next succeeding Dividend Period thereof will be the Maximum Applicable Rate on the Auction Date therefor. In such event, Beneficial Owners of New Preferred Shares that have submitted or are deemed to have submitted Sell Orders may not be able to sell in such Auction all shares subject to such Sell Orders. If all of the Outstanding New Preferred Shares are the subject of Submitted Hold Orders, then the Dividend Period next succeeding the Auction shall automatically be the same length as the immediately preceding Dividend Period and the Applicable Rate for the next succeeding Dividend Period will be the higher of the 30-day "AA" Composite Commercial Paper Rate and the Taxable Equivalent of the Short-Term Municipal Bond Rate multiplied by 1 minus the maximum marginal regular Federal individual income tax rate then applicable to ordinary income or the maximum marginal regular Federal corporate tax rate then applicable, whichever is greater (or 90% of such rate if the Trust has provided notification to the Auction Agent prior to the Auction establishing the Applicable Rate that net capital gains or other taxable income will be included in such dividend on New Preferred Shares) on the date of the Auction.

The Auction Procedures include a pro rata allocation of shares for purchase and sale, which may result in an Existing Holder continuing to hold or selling, or a Potential Holder purchasing, a number of New Preferred Shares that is different than the number of shares specified in its Order. To the extent the allocation procedures have that result, Broker-Dealers that have designated themselves as Existing Holders or Potential Holders in respect of customer Orders will be required to make appropriate pro rata allocations among their respective customers.

Settlement of purchases and sales will be made on the next Business Day (also a Dividend Payment Date) after the Auction Date through the Securities Depository. Purchasers will make payment through their Agent Members in same-day funds to the Securities Depository against delivery to their respective Agent Members. The Securities Depository will make payment to the sellers' Agent Members in accordance with the Securities Depository's normal procedures, which now provide for payment against delivery by their Agent Members in same-day funds.

The Auctions for New Preferred Shares will normally be held every Tuesday, and each subsequent Dividend Period will normally begin on the following Wednesday.

Whenever the Trust intends to include any net capital gains or other income taxable for Federal income tax purposes in any dividend on New Preferred Shares, the Trust may, at its election, notify the Auction Agent of the amount to be so included not later than the Dividend Payment Date next preceding the Auction Date on which the Applicable Rate for such dividend is to be established. Whenever the Auction Agent receives such notice from the Trust, it will be required in turn to notify each Broker-Dealer, who, on or prior to such Auction Date, in accordance with its Broker-Dealer Agreement, will be required to notify its customers who are Beneficial Owners and Potential Beneficial Owners believed by it to be interested in submitting an Order in the Auction to be held on such Auction Date. In the event of such notice, the Trust will not be required to pay an Additional Dividend with respect to such dividend.

SECONDARY MARKET TRADING AND TRANSFER OF NEW PREFERRED SHARES

The Broker-Dealers are expected to maintain a secondary trading market in New Preferred Shares outside of Auctions, but are not obligated to do so, and may discontinue such activity at any time. There can be no assurance that any secondary trading market in New Preferred Shares will provide owners with liquidity of investment. The New Preferred Shares are not registered on any stock exchange or on the Nasdaq Stock Market. Investors who purchase shares in an Auction for a Special Dividend Period in which the Bid Requirements, if any, do not require a Bid to specify a Spread, should note that because the dividend rate on such shares will be fixed for the length of such Dividend Period, the value of the shares may fluctuate in response to changes in interest rates, and may be more or less than their original cost if sold on the open market in advance of the next Auction therefor, depending upon market conditions. Investors who purchase shares in an Auction for a Special Dividend Period in which the Bid Requirements require a Bid to specify a Spread should be aware that the value of their shares may also fluctuate and may be more or less than their original cost if sold on the open market in advance of the next Auction, particularly if market spreads narrow or widen in a manner unfavorable to such purchaser's position.

A Beneficial Owner or an Existing Holder may sell, transfer or otherwise dispose of New Preferred Shares only in whole shares and only:

o pursuant to a Bid or Sell Order placed with the Auction Agent in accordance with the Auction Procedures;

o to a Broker-Dealer; or

o to such other persons as may be permitted by the Trust;

provided, however, that

--------  -------

     o    a sale, transfer or other disposition of New Preferred Shares
          from a customer of a Broker-Dealer who is listed on the records
          of that Broker-Dealer as the holder of such shares to that
          Broker- Dealer or another customer of that Broker-Dealer shall
          not be deemed to be a sale, transfer or other disposition for
          purposes of the foregoing if such Broker-Dealer remains the
          Existing Holder of the shares so sold, transferred or disposed of
          immediately after such sale, transfer or disposition; and

     o    in the case of all transfers other than pursuant to Auctions, the
          Broker-Dealer (or other person, if permitted by the Trust) to
          whom such transfer is made shall advise the Auction Agent of such
          transfer.

         For the meaning of defined terms used but not defined, see the

Articles Supplementary and Articles of Amendment attached as Appendices B-1, B-2 and B-3 to the statement of additional information.

TAXES

FEDERAL INCOME TAX MATTERS

The Trust has qualified and elected, and intends to continue to qualify, as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"), and intends to distribute at least 90% of its net investment income (including taxable income, tax-exempt interest and net short-term capital gain, but not net capital gain, which is the excess of net long-term capital gain over net short-term capital loss) and substantially all of its net capital gain to its shareholders. The Trust will not be subject to Federal income tax on any net investment income and net capital gain that it distributes to its shareholders, but will be subject to Federal income tax at the regular corporate income tax rate on any net investment income (other than net tax-exempt interest income) that it retains.

The Trust expects that substantially all of the Trust's dividends to the common shareholders and Preferred Shareholders will qualify as "exempt-interest dividends." A shareholder treats an exempt-interest dividend as interest on state and local bonds which is exempt from regular Federal income tax. Some or all of an exempt-interest dividend, however, may be subject to Federal alternative minimum tax imposed on the shareholder. Different Federal alternative minimum tax rules apply to individuals and to corporations. In addition to exempt-interest dividends, the Trust also may distribute to its shareholders amounts that are treated as long-term capital gain or ordinary income. The Trust will allocate distributions to shareholders that are treated as tax-exempt interest and as long-term capital gain and ordinary income, if any, proportionately among the common shares and Preferred Shares, including the New Preferred Shares. The Trust intends to notify Preferred Shares, including New Preferred Shares in advance if it will allocate income to them that is not exempt from regular Federal income tax. In certain circumstances the Trust will make payments to such shareholders to offset the tax effects of the taxable distribution. See "Description of New Preferred Shares--Dividends and Dividend Periods-Additional Dividends."

The sale or other disposition of common shares or Preferred Shares of the Trust will normally result in capital gain or loss to shareholders. Present law taxes both long-term and short-term capital gains of corporations at the rates applicable to ordinary income. For non-corporate taxpayers, under current law short-term capital gains and ordinary income will be taxed at a maximum rate of 39.6%, while long-term capital gains will generally be taxed at a maximum rate of 20%. Because of certain limitations on itemized deductions and the deduction for personal exemptions applicable to higher income taxpayers, the effective rate of tax may be higher in certain circumstances. Losses realized by a shareholder on the sale or exchange of shares of the Trust held for six months or less are disallowed to the extent of any exempt- interest dividends received with respect to such shares, and, if not disallowed, such losses are treated as long-term capital losses to the extent of any distribution of net capital gain received with respect to such shares. A shareholder's holding period is suspended for any periods during which the shareholder's risk of loss is diminished as a result of holding one or more other positions in substantially similar or related property, or through certain options or short sales. Any loss realized on a sale or exchange of shares of the Trust will be disallowed to the extent those shares of the Trust are replaced by other shares within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the original shares. In that event, the basis of the replacement shares of the Trust will be adjusted to reflect the disallowed loss.

The statement of additional information contains a more detailed summary of the Federal tax rules that apply to the Trust and its shareholders. Legislative, judicial or administrative action may change the tax rules that apply to the Trust or its shareholders, and any such change may be retroactive. You should consult with your tax adviser about Federal income tax matters.

STATE AND LOCAL TAX MATTERS

While exempt-interest dividends are exempt from regular Federal income tax, they may not be exempt from state or local income or other taxes. Some states exempt from state income tax that portion of any exempt-interest dividend that is derived from interest that a regulated investment company receives on its holdings of securities of that state and its political subdivisions and instrumentalities. Therefore, the Trust will report annually to its shareholders the percentage of interest income the Trust earned during the preceding year on tax-exempt obligations and the Trust will indicate, on a state-by-state basis, the source of this income. You should consult with your tax adviser about state and local tax matters.

DETERMINATION OF NET ASSET VALUE

The net asset value of common shares of the Trust will be computed based upon the value of the Trust's portfolio securities and other assets. Net asset value per common share of the Trust will be determined as of the close of the regular trading session on the New York Stock Exchange no less frequently than Friday of each week and the last business day of each month, provided, however, that if any such day is a holiday or determination of net asset value on such day is impracticable, the net asset value shall be calculated on such earlier or later day as determined by the Adviser. The Trust calculates net asset value per common share of the Trust by subtracting the Trust's liabilities (including accrued expenses, dividends payable and any borrowings of the Trust) and the liquidation value of any outstanding preferred shares (including New Preferred Shares) of the Trust from the Trust's total assets (the value of the securities the Trust holds plus cash or other assets, including interest accrued but not yet received) and dividing the result by the total number of common shares of the Trust outstanding.

The Trust values its fixed income securities by using market quotations provided by pricing services, prices provided by market makers or estimates of market values obtained from yield data relating to instruments or securities with similar characteristics in accordance with procedures established by the board of directors of the Trust. Short-term securities having a remaining maturity of 60 days or less are valued at amortized cost, which approximates market value. Any securities or other assets for which current market quotations are not readily available are valued at their 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.

REPURCHASE OF COMMON SHARES

Shares of closed-end investment companies often trade at a discount to their net asset values, and the Trust's common shares may also trade at a discount to their net asset value. The market price of the Trust's common shares will be determined by such factors as relative demand for and supply of such common shares in the market, the Trust's net asset value, general market and economic conditions and other factors beyond the control of the Trust. Although the Trust's common shareholders will not have the right to redeem their common shares, the Trust may take action to repurchase common shares in the open market or make tender offers for its common shares at their net asset value. This may, but will not necessarily, have the effect of reducing any market discount from net asset value. See "Repurchase of Common Shares" in the statement of additional information.

DESCRIPTION OF CAPITAL STOCK

The Trust is authorized to issue 200 million shares of capital stock, $.01 par value. The board of directors of the Trust is authorized to classify and reclassify any unissued shares of capital stock from time to time by setting or changing the preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications or terms or conditions of redemption of such shares of stock. In connection with the offerings of New Preferred Shares described herein, the board of directors has reclassified 662 shares of unissued capital stock as New Preferred Shares.

COMMON SHARES

The Trust has no present intention of offering any additional shares of capital stock other than New Preferred Shares as described herein. Any additional offerings of shares of capital stock, if made, will require approval by the Trust's board of directors. Any additional offering of common shares will be subject to the requirements of the 1940 Act that common shares may not be issued at a price below the then current net asset value (exclusive of underwriting discounts and commissions) except in connection with an offering to existing stockholders or with the consent of a majority of the Trust's common shareholders.

On December 31, 1999, there were 16,707,093 common shares of the Trust issued and outstanding.

So long as any New Preferred Shares or any other preferred shares of the Trust are outstanding, holders of common shares of the Trust will not be entitled to receive any net income of or other distributions from the Trust unless all accumulated dividends on outstanding preferred shares (including the New Preferred Shares) have been paid, and unless asset coverage (as defined in the 1940 Act) with respect to such preferred shares would be at least 200% after giving effect to such distributions. See "Description of New Preferred Shares-Dividends and Dividend Periods" for other restrictions on dividends to holders of common shares which will be applicable for so long as any preferred shares of the Trust are outstanding.

The common shares have traded on the New York Stock Exchange (the "Exchange") since February 19, 1992 under the symbol "BKN."

PREFERRED STOCK

Under the Trust's charter, the Trust is authorized to issue 200 million shares of capital stock, $.01 par value. The board of directors of the Trust is authorized to classify and reclassify any unissued shares of capital stock from time to time by setting or changing the preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications or terms or conditions of redemption of such shares of stock. In connection with the offerings of New Preferred Shares described herein, the board of directors has reclassified 662 shares of unissued capital stock as New Preferred Shares. Under the 1940 Act, the Trust is permitted to have outstanding more than one series of preferred shares so long as no single series has a priority over another series as to the distribution of assets of the Trust or the payment of dividends. Holders of common shares and outstanding preferred shares of the Trust have no preemptive right to purchase any preferred shares (including the New Preferred Shares) that might be issued. It is anticipated that the net asset value per share of the New Preferred Stock will equal its original purchase price per share plus accrued dividends per share. See "Description of New Preferred Shares" for a description of the rights, preferences, privileges and other terms of the New Preferred Shares.

ANTITAKEOVER PROVISIONS OF THE CHARTER AND BY-LAWS

The Trust presently has provisions in its charter and By-Laws (commonly referred to as "antitakeover" provisions) which may have the effect of limiting the ability of other entities or persons to acquire control of the Trust, to cause it to engage in certain transactions or to modify its structure.

First, a director elected by the holders of capital stock (i.e., the common shares, the New Preferred Shares and any other preferred shares) or by the holders of Preferred Shares, including the New Preferred Shares, and any other preferred shares may be removed from office only for cause by vote of the holders of at least 75% of the shares of capital stock or preferred shares, as the case may be, of the Trust entitled to be voted on the matter. Second, the affirmative vote of a majority of the directors and of the holders of at least 75% of the Trust's outstanding shares of capital stock entitled to be voted on the matter, voting as a single class, and the affirmative vote of a majority of outstanding preferred shares, voting as a separate class, will be required to authorize the Trust's conversion from a closed-end to an open-end investment company, which conversion would result in delisting of the common shares from the New York Stock Exchange. Conversion to an open-end investment company would require redemption of all outstanding preferred shares of the Trust. Third, the board of directors is classified into three classes, each with a term of three years with only one class of directors standing for election in any year. Such classification may prevent replacement of a majority of the directors for up to a two year period. The affirmative vote of at least 75% of the Trust's outstanding shares of capital stock entitled to be voted on the matter, voting as a single class, and the affirmative vote of a majority of outstanding preferred shares, voting as a separate class will be required to amend the charter or By-Laws to change any of the foregoing provisions.

In addition, under the Trust's charter, the Trust has elected to be subject to provisions of the Maryland General Corporation Law that generally provide that, unless an exemption is available, certain mergers, consolidations, shares exchanges, asset sales, stock issuances, liquidations or dissolutions, recapitalizations, and other transaction ("Business Combinations") with a beneficial owner of 10% or more of the voting power of a Maryland corporation (an "Interested Stockholder") or any affiliate of an Interested Stockholder are prohibited for a period of five years following the most recent date on which the Interested Stockholder became an Interested Stockholder. Thereafter, such a Business Combination must be recommended by the board of directors and approved by the affirmative vote of at least (i) 80% of the votes entitled to be cast by outstanding shares of voting stock of the corporation and (ii) 662/3% of the votes entitled to be cast by holders of voting stock other than voting stock held by the Interested Stockholder who is (or whose affiliate is) a party to the Business Combination or an affiliate or associate of the Interested Stockholder (with dissenting stockholders having certain appraisal rights), unless certain value and other standards are satisfied or some other statutory exemption is available. The vote specified in the preceding sentence will be required to amend the charter to change the provisions subjecting the Trust to the provisions of the Maryland General Corporation Law discussed above.

The percentage of votes required under these provisions, which are greater than the minimum requirements under Maryland law absent the elections described above or in the 1940 Act, will make more difficult a change in the Trust's business or management and may have the effect of depriving holders of common shares of an opportunity to sell shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Trust in a tender offer or similar transaction. The Trust's board of directors, however, has considered these antitakeover provisions and believes they are in the best interests of shareholders.

CUSTODIAN

The Trust's securities and cash are held under a Custodial Agreement with State Street Bank and Trust Company (the "Custodian"), 225 Franklin Street, Boston, Massachusetts.

UNDERWRITING

Subject to the terms and conditions of the underwriting agreement dated the date hereof, each underwriter named below has severally agreed to purchase, and the Trust has agreed to sell to such underwriter, the number of New Preferred Shares set forth opposite the name of such underwriter.

                                          Number of

Total ............... 662

The underwriting agreement provides that the obligations of the underwriters to purchase the shares included in this offering are subject to the approval of certain legal matters by counsel and to certain other conditions. The underwriters are obligated to purchase all the New Preferred Shares if they purchase any of the shares. In the underwriting agreement, the Trust and the Adviser have agreed to indemnify the underwriters against certain liabilities, including liabilities arising under the Securities Act of 1933, or to contribute payments the underwriters may be required to make for any of those liabilities.

The underwriters, for whom ___________ [and ] are acting as representatives, propose to initially offer some of the New Preferred Shares directly to the public at the public offering price set forth on the cover page of this prospectus and some of the New Preferred Shares to certain dealers at the public offering price less a concession not in excess of $ per share. The sales load the Trust will pay of per share is equal to % of the initial offering price. The underwriters may allow, and such dealers may reallow, a concession not in excess of $ per share on sales to certain other dealers. After the initial public offering, the underwriters may change the public offering price and the concession. Investors must pay for any New Preferred Shares purchased in the initial public offering on or before , 2000.

The Trust anticipates that the underwriters may from time to time act as brokers or dealers in executing the Trust's portfolio transactions after they have ceased to be underwriters. The underwriters are active underwriters of, and dealers in, securities and act as market makers in a number of such securities, and therefore can be expected to engage in portfolio transactions with the Trust.

The Trust anticipates that the underwriters or their respective affiliates may, from time to time, act in Auctions as Broker-Dealers and receive fees as set forth under "The Auction." [Each of such firms may also provide information to be used in ascertaining the applicable reference rates.] Each of the underwriters engages in transactions with, and perform services for, the Trust in the ordinary course of business.

* Net amount subject to Federal personal income tax after deductions and exemptions.

The above indicated Federal income tax brackets do not take into account the effect of a reduction in the deductibility of itemized deductions for individual taxpayers with adjusted gross income in excess of $128,950. The tax brackets also do not show the effects of phaseout of personal exemptions for single filers with adjusted gross income in excess of $128,950 and joint filers with adjusted gross income in excess of $193,400. The effective tax brackets and equivalent taxable yields of those taxpayers will be higher than those indicated above.

Yields shown are for illustration purposes only and are not meant to represent the Trust's actual yield. No assurance can be given that the Trust will achieve any specific tax-exempt yield. While it is expected that the Trust will invest principally in obligations the interest from which is exempt from the regular Federal income tax, other income received by the Trust may be taxable. The table does not take into account state or local taxes, if any, payable on Trust distributions. It should also be noted that the interest earned on certain "private activity bonds", while exempt from the regular Federal income tax, is treated as a tax preference item which could subject the recipient to the AMT. The illustrations assume that the AMT is not applicable and do not take into account any tax credits that may be available.

The information set forth above is as of the date of this prospectus. Subsequent tax law changes could result in prospective or retroactive changes in the tax brackets, tax rates, and tax-equivalent yields set forth above. Investors should consult their tax adviser for additional information.

INVESTMENT OBJECTIVE AND POLICIES

Although the Trust does not ordinarily invest in municipal obligations subject to the Federal alternative minimum tax ("AMT") and expects that no more than 20% of its assets will be invested in municipal obligations subject to such tax at any time, all or a portion of the Trust's dividends may be subject to AMT. New Preferred Shares therefore may not be a suitable investment for investors who are subject to AMT or who would become subject to such tax by purchasing New Preferred Shares. The suitability of an investment in New Preferred Shares will depend upon a comparison of the after-tax yield likely to be provided from the Trust with that from comparable tax-exempt investments not subject to AMT, and from comparable fully taxable investments, in light of each such investor's tax position. Special considerations apply to corporate investors. See "Tax Matters."

The types of municipal obligations in which the Trust may invest include general obligation bonds, revenue bonds, municipal lease obligations, installment purchase contract obligations, variable and floating rate obligations, zero coupon securities, tax-exempt notes and municipal commercial paper.

The two principal classifications of municipal obligations are "general obligation" bonds and "revenue" bonds. General obligation bonds are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source. Industrial development, private activity and pollution control bonds are in most cases revenue bonds and do not generally constitute the pledge of the credit or taxing power of the issuer of such bonds. There are, of course, depending on numerous factors, variations in the quality of municipal obligations both within a particular classification and between classifications.

Also included within the general category of municipal obligations are certain lease obligations or installment purchase contract obligations and participations therein (hereinafter collectively called "lease obligations") of municipal authorities or entities. Although lease obligations do not constitute general obligations of the municipality for which the municipality's taxing power is pledged, a lease obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the lease obligation. Interest on lease obligations is tax- exempt to the same extent as if the municipality had issued debt obligations to finance the underlying project or purchase. However, certain lease obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. In addition to the "non-appropriation" risk, these securities represent a relatively new type of financing that has not yet developed the depth of marketability associated with more conventional bonds and some lease obligations may be illiquid. Although "non-appropriation" lease obligations are generally secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. In addition, the tax treatment of such obligations in the event of non-appropriation is unclear. The Trust does not intend to invest more than 10% of its total assets in lease obligations that contain "non-appropriation" clauses.

The Trust invests a portion of its assets in municipal obligations that pay interest at a coupon rate equal to a base rate plus additional interest for a certain period of time if short-term interest rates rise above a predetermined level or "cap." Although the specific terms of these municipal obligations may differ, the amount of any additional interest payment typically is calculated pursuant to a formula based upon an applicable short-term interest rate index multiplied by a designated factor. This use of a designated factor in the calculation of additional interest effectively multiplies the underlying principal amount of these municipal obligations and the Trust will attempt under normal market conditions to purchase a sufficient amount of these securities so that the "notional principal" on which any additional interest is calculated is equal to at least 100% of the liquidation preference of the Trust's outstanding Preferred Shares. The Adviser believes that during periods of sharp increases in short-term interest rates, the total coupon rate payable on these municipal obligations frequently would exceed prevailing short-term interest rates. The additional interest component of the coupon rate of these municipal obligations generally expires before the maturity of the underlying instrument. These municipal obligations may also contain provisions that provide for conversion at the option of the issuer to constant interest rates in addition to standard call features. Under normal market conditions, the Trust invests approximately 15-25% of its total assets in these municipal obligations. There can be no assurance that these securities will continue to be available at current levels or otherwise, and they may be subject to greater volatility than other municipal obligations.

Certain municipal obligations may carry variable or floating rates of interest whereby the rate of interest is not fixed but varies with changes in specified market rates or indices, such as a bank prime rate or a tax-exempt money market index. Accordingly, the yield on such obligations can be expected to fluctuate with changes in prevailing interest rates.

Other municipal obligations include zero coupon securities, which are debt obligations that do not entitle the holder to any periodic payments prior to maturity and are issued and traded at a discount from their face amounts. The discount varies depending on the time remaining until maturity, prevailing interest rates, liquidity of the security and perceived credit quality of the issuer. Zero coupon municipal obligations may be created by investment banks under proprietary programs in which they strip the interest component from the principal component and sell both separately. The market prices of zero coupon securities are generally more volatile than the market prices of securities that pay interest periodically and are likely to respond to changes in interest rates to a greater degree than do securities having similar maturities and credit quality that do pay periodic interest.

The Trust may acquire custodial receipts or certificates underwritten by securities dealers or banks that evidence ownership of future interest payments principal payments or both on certain municipal obligations. The underwriter of these certificates or receipts typically purchases municipal obligations and deposits the obligations in an irrevocable trust or custodial account with a custodian bank which then issues receipts or certificates that evidence ownership of the periodic unmatured coupon payments and the final principal payment on the obligations. Custodial receipts evidencing specific coupon or principal payments have the same general attributes as zero coupon municipal obligations described above. Although under the terms of a custodial receipt, the Trust typically would be authorized to assert its rights directly against the issuer of the underlying obligations, the Trust could be required to assert through the custodian bank those rights as may exist against the underlying issuer. Thus, in the event the underlying issuer fails to pay principal and/or interest when due, the Trust may be subject to delays, expenses and risks that are greater than those that would have been involved if the Trust had purchased a direct obligation of the issuer. In addition, in the event that the trust or custodial account in which the underlying security has been deposited is determined to be an association taxable as a corporation, instead of a non-taxable entity, the yield on the underlying security would be reduced in recognition of any taxes paid.

The Trust may also invest in municipal obligations the interest rate on which has been divided by the issuer into two different and variable components, which together result in a fixed interest rate. Typically, the first of the components (the "Auction Component") pays an interest rate that is reset periodically through an auction process, whereas the second of the components (the "Residual Component") pays a residual interest rate based on the difference between the total interest paid by the issuer on the municipal obligation and the auction rate paid on the Auction Component. The Trust may purchase both Auction and Residual Components.

Because the interest rate paid to holders of Residual Components is generally determined by subtracting the interest rate paid to the holders of Auction Components from a fixed amount, the interest rate paid to Residual Component holders will decrease as the Auction Component's rate increases and increase as the Auction Component's rate decreases. Moreover, the extent of the increases and decreases in market value of Residual Components may be larger than comparable changes in the market value of an equal principal amount of a fixed rate municipal obligation having similar credit quality, redemption provisions and maturity.

The term municipal obligations also includes obligations, such as tax-exempt notes, municipal commercial paper and municipal lease obligations, having relatively short-term maturities.

INVESTMENT RESTRICTIONS

The Trust's investment objective and the following investment restrictions are fundamental and cannot be changed without the approval of the holders of a majority of the Trust's outstanding voting securities (defined in the 1940 Act as the lesser of (a) more than 50% of the outstanding shares (including common shares, New Preferred Shares and any other outstanding preferred shares) or (b) 67% or more of the shares (including common shares and New Preferred Shares and any other outstanding preferred shares) represented at a meeting at which more than 50% of the outstanding shares (including common shares and New Preferred Shares and any other outstanding preferred shares) are represented) and the approval of the holders of a majority of New Preferred Shares and any other outstanding preferred shares voting separately as a class. All other investment policies or practices are considered by the Trust not to be fundamental and accordingly may be changed without stockholder approval. If a percentage restriction on investment or use of assets set forth below is adhered to at a time a transaction is effected, later changes in percentage resulting from changing market values will not be considered a deviation from policy. The Trust may not:

(1) with respect to 75% of its total assets, invest more than 5% of the value of its total assets (taken at market value at time of purchase) in the outstanding securities of any other issuer or own more than 10% of the outstanding voting securities of any one issuer, in each case other than securities issued or guaranteed by the U.S. government or any agency or instrumentality thereof or other investment companies;

(2) invest 25% of more of the value of its total assets in any one industry provided that such limitation shall not be applicable to municipal obligations other than those municipal obligations backed only by assets and revenues of non-governmental users;

(3) issue senior securities other than (a) preferred shares not in excess of the excess of 50% of its total assets over any senior securities described in clause (b) below that are outstanding, (b) senior securities other than preferred shares (including borrowing money, including on margin if margin securities are owned and through entering into reverse repurchase agreements) not in excess of 331/3% of its total assets, and (c) borrowings up to 5% of its total assets for temporary purposes without regard to the amount of senior securities outstanding under clauses (a) and (b) above; provided, however, that the Trust's obligations under interest rate swaps, when issued and forward commitment transactions and similar transactions are not treated as senior securities if covering assets are appropriately segregated; or pledge its assets other than to secure such issuances or in connection with Hedging Transactions, short sales, when-issued and forward commitment transactions and similar investment strategies. For purposes of clauses (a), (b) and (c) above, "total assets" shall be calculated after giving effect to the net proceeds of any such issuance and net of any liabilities and indebtedness that do not constitute senior securities except for such liabilities and indebtedness as are excluded from treatment as senior securities by the proviso to this item (3);

(4) make loans of money or property to any person, except through loans of portfolio securities, the purchase of fixed income securities consistent with the Trust's investment objective and policies or the acquisition of securities subject to repurchase agreements;

(5) underwrite the securities of other issuers, except to the extent that in connection with the disposition of portfolio securities or the sale of its own shares the Trust may be deemed to be an underwriter;

(6) invest for the purpose of exercising control over any issuer, except that the Trust may control a portfolio subsidiary;

(7) purchase or sell real estate or interests therein other than municipal obligations secured by real estate or interests therein;

(8) purchase or sell commodities or commodity contracts except for purposes, and only to the extent, permitted by applicable law without the Trust becoming subject to registration with the Commodity Futures Trading Commission as a commodity pool; or

(9) make any short sale of securities except in conformity with applicable laws, rules and regulations and unless, giving effect to such sale, the market value of all securities sold short does not exceed 25% of the value of the Trust's total assets and the Trust's aggregate short sales of a particular class of securities does not exceed 25% of the then outstanding securities of that class.

The Trust has no intention to file a voluntary application for relief under Federal bankruptcy law of any similar application under state law for as long as the Trust is solvent and does not foresee becoming insolvent.

INVESTMENT POLICIES AND TECHNIQUES

The following information supplements the discussion of the Trust's investment objective, policies and techniques that are described in the prospectus.

HEDGING TRANSACTIONS

The following descriptions of types of hedging transactions in which the Trust may engage supplements the information in the prospectus under the caption "Other Investment Practices -- Hedging." For additional information, see Appendix A "General Characteristics and Risks of Hedging Transactions."

Interest Rate Transactions. Among the Hedging Transactions into which the Trust may enter are interest rate swaps and the purchase or sale of interest rate caps and floors. The Trust expects to enter into these transactions primarily to preserve a return or spread on a particular investment or portion of its portfolio as a duration management technique or to protect against any increase in the price of securities the Trust anticipates purchasing at a later date. The Trust intends to use these transactions as a hedge and not as a speculative investment. The Trust will not sell interest rate caps or floors that it does not own. Interest rate swaps involve the exchange by the Trust with another party of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal. The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index exceeds a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate cap. The purchase of an interest rate floor entitles the purchaser, to the extent that a specified index falls below a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate floor.

The Trust may enter into interest rate swaps, caps and floors on either an asset-based or liability-based basis, depending on whether it is hedging its assets or liabilities, and will usually enter into interest rate-swaps on a net basis, i.e., the two payment streams are netted out, with the Trust receiving or paying, as the case may be, only the net amount of the two payments on the payment dates. Inasmuch as these Hedging Transactions are entered into for good faith hedging purposes, the Adviser and the Trust believe such obligations do not constitute senior securities and, accordingly, will not treat them as being subject to its borrowing restrictions. The Trust will accrue the net amount of the excess, if any, of the Trust's obligations over its entitlements with respect to each interest rate swap on a daily basis and will segregate with a custodian an amount of cash or liquid securities having an aggregate net asset value at least equal to the accrued excess. The Trust will not enter into any interest rate swap, cap or floor transaction unless the unsecured senior debt or the claims-paying ability of the other party thereto is rated in the highest rating category of at least one nationally recognized rating organization at the time of entering into such transaction. If there is a default by the other party to such a transaction, the Trust will have contractual remedies pursuant to the agreements related to the transaction. The swap market has grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. Caps and floors are more recent innovations for which standardized documentation has not yet been developed and, accordingly, they are less liquid than swaps.

Futures Contracts and Options on Futures Contracts. In connection with its hedging and other risk management strategies, the Trust may also enter into contracts for the purchase or sale for future delivery ("futures contracts") of debt securities, aggregates of debt securities, financial indices, and U.S. Government debt securities or options on the foregoing to hedge the value of its portfolio securities that might result from a change in interest rates or market movements. The Trust will engage in such transactions only for bona fide hedging, risk management and other appropriate portfolio management purposes, in each case, in accordance with the rules and regulations of the Commodity Futures Trading Commission.

Calls on Securities Indices and Futures Contracts. In order to enhance income or reduce fluctuations in net asset value, the Trust may sell or purchase call options ("calls") on municipal obligations and indices based upon the prices of debt securities that are traded on US. securities exchanges and in the over-the-counter markets. A call option gives the purchaser of the option the right to buy, and obligates the seller to sell, the underlying security, futures contract or index at the exercise price at any time or at a specified time during the option period. All such calls sold by the Trust must be "covered" as long as the call is outstanding (i.e., the Trust must own the instrument subject to the call or other securities or assets acceptable for applicable segregation and coverage requirements). A call sold by the Trust exposes the Trust during the term of the option to possible loss of opportunity to realize appreciation in the market price of the underlying security, index or futures contract and may require the Trust to hold an instrument which it might otherwise have sold. The purchase of a call gives the Trust the right to buy the underlying instrument or index at a fixed price. Calls on futures contracts on municipal obligations written by the Trust must also be covered by assets or instruments acceptable under applicable segregation and coverage requirements.

Puts on Securities Indices and Futures Contracts. As with calls, the Trust may purchase put options ("puts") on municipal obligations (whether or not it holds such securities in its portfolio). For the same purposes the Trust may also sell puts on municipal obligations financial indices and puts on futures contracts on municipal obligations if the Trust's contingent obligations on such puts are secured by segregated assets consisting of cash or liquid high grade debt securities having a value not less than the exercise price. The Trust will not sell puts if, as a result, more than 50% of the Trust's assets would be required to cover its potential obligation under its hedging and other investment transactions. In selling puts, there is a risk that the Trust may be required to buy the underlying instrument or index at higher than the current market price.

The principal risks relating to the use of Hedging Transactions are: (i) less than perfect correlation between the prices of the hedging instrument and the market value of the securities in the Trust's portfolio;
(ii) possible lack of a liquid secondary market for closing out a position in such instruments; (iii) losses resulting from interest rate or other market movements not anticipated by the Adviser; and (iv) the obligation to meet additional variation margin or other payment requirements. See Appendix A "General Characteristics and Risks of Hedging Transactions."

Certain provisions of the Internal Revenue Code of 1986, as amended (the "Code"), may restrict or affect the ability of the Trust to engage in Hedging Transactions. See "Tax Matters" and the prospectus.

OTHER INVESTMENT POLICIES AND TECHNIQUES

Restricted and Illiquid Securities. Certain of the Trust's investments may be illiquid. Illiquid securities are subject to legal or contractual restrictions on disposition or lack an established secondary trading market. The sale of restricted and illiquid securities often requires more time and results in higher brokerage charges or dealer discounts and other selling expenses than does the sale of securities eligible for trading on national securities exchanges or in the over- the-counter markets. Restricted securities may sell at a price lower than similar securities that are not subject to restrictions on resale.

Repurchase Agreements. The Trust may invest temporarily, without limitation, in repurchase agreements, which are agreements pursuant to which securities are acquired by the Trust from a third party with the understanding that they will be repurchased by the seller at a fixed price on an agreed date. These agreements may be made with respect to any of the portfolio securities in which the Trust is authorized to invest. Repurchase agreements may be characterized as loans secured by the underlying securities. The Trust may enter into repurchase agreements with (i) member banks of the Federal Reserve System having total assets in excess of $500 million and (ii) securities dealers, provided that such banks or dealers meet the creditworthiness standards established by the Trust's board of directors ("Qualified Institutions"). The Adviser will monitor the continued creditworthiness of Qualified Institutions, subject to the supervision of the Trust's board of directors. The resale price reflects the purchase price plus an agreed upon market rate of interest which is unrelated to the coupon rate or date of maturity of the purchased security. The collateral is marked to market daily. Such agreements permit the Trust to keep all its assets earning interest while retaining "overnight" flexibility in pursuit of investments of a longer-term nature.

The use of repurchase agreements involves certain risks. For example, if the seller of securities under a repurchase agreement defaults on its obligation to repurchase the underlying securities, as a result of its bankruptcy or otherwise, the Trust will seek to dispose of such securities, which action could involve costs or delays. If the seller becomes insolvent and subject to liquidation or reorganization under applicable bankruptcy or other laws, the Trust's ability to dispose of the underlying securities may be restricted. Finally, it is possible that the Trust may not be able to substantiate its interest in the underlying securities. To minimize this risk, the securities underlying the repurchase agreement will be held by the custodian at all times in an amount at least equal to the repurchase price, including accrued interest. If the seller fails to repurchase the securities, the Trust may suffer a loss to the extent proceeds from the sale of the underlying securities are less than the repurchase price.

Reverse Repurchase Agreements. The Trust may enter into reverse repurchase agreements with respect to its portfolio investments subject to the investment restrictions set forth herein and in the prospectus. Reverse repurchase agreements involve the sale of securities held by the Trust with an agreement by the Trust to repurchase the securities at an agreed upon price, date and interest payment. At the time the Trust enters into a reverse repurchase agreement, it may establish and maintain a segregated account with its custodian containing liquid instruments having a value not less than the repurchase price (including accrued interest). If the Trust establishes and maintains such a segregated account, a reverse repurchase agreement will not be considered a borrowing by the Trust; however, under circumstances in which the Trust does not establish and maintain such a segregated account, such reverse repurchase agreement will be considered a borrowing for the purpose of the Trust's limitation on borrowings. The use by the Trust of reverse repurchase agreements involves many of the same risks of leverage since the proceeds derived from such reverse repurchase agreements may be invested in additional securities. Reverse repurchase agreements involve the risk that the market value of the securities acquired in connection with the reverse repurchase agreement may decline below the price of the securities the Trust has sold but is obligated to repurchase. Also, reverse repurchase agreements involve the risk that the market value of the securities retained in lieu of sale by the Trust in connection with the reverse repurchase agreement may decline in price.

If the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, such buyer or its trustee or receiver may receive an extension of time to determine whether to enforce the Trust's obligation to repurchase the securities, and the Trust's use of the proceeds of the reverse repurchase agreement may effectively be restricted pending such decision. Also, the Trust would bear the risk of loss to the extent that the proceeds of the reverse repurchase agreement are less than the value of the securities subject to such agreement.

When-Issued and Forward Commitment Securities. The Trust may purchase municipal obligations on a "when- issued" basis and may purchase or sell municipal obligations on a "forward commitment" basis in order to hedge against anticipated changes in interest rates and prices. When such transactions are negotiated, the price, which is generally expressed in yield terms, is fixed at the time the commitment is made, but delivery and payment for the securities take place at a later date. When-issued securities and forward commitments may be sold prior to the settlement date, but the Trust will enter into when-issued and forward commitments only with the intention of actually receiving or delivering the securities, as the case may be. If the Trust disposes of the right to acquire a when-issued municipal obligation prior to its acquisition or disposes of its right to deliver or receive against a forward commitment, it might incur a gain or loss. At the time the Trust enters into a transaction on a when-issued or forward commitment basis, it will segregate with the custodian cash or liquid high grade debt securities with a value not less than the value of the when-issued or forward commitment securities. The value of these assets will be monitored daily to ensure that their marked to market value will at all times equal or exceed the corresponding obligations of the Trust. There is always a risk that the securities may not be delivered and that the Trust may incur a loss. Settlements in the ordinary course, which may take substantially more than five business days, are not treated by the Trust as when-issued or forward commitment transactions and accordingly are not subject to the foregoing restrictions.

Borrowings. Although it has no present intention of doing so, the Trust receives the right to borrow funds to the extent permitted as described under the caption "Investment Objective and Policies -- Investment Restrictions." The proceeds of borrowings may be used for any valid purpose including, without limitation, liquidity, investing and repurchases of capital stock of the Trust. Borrowing is a form of leverage and, in that respect, entails risks, including volatility in net asset value, market value and income available for distribution.

Lending of Securities. The Trust may lend its portfolio securities to Qualified Institutions. By lending its portfolio securities, the Trust attempts to increase its income through the receipt of interest on the loan. Any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Trust. The Trust may lend its portfolio securities so long as the terms and the structure of such loans are not inconsistent with requirements of the 1940 Act, which currently require that (i) the borrower pledge and maintain with the Trust collateral consisting of cash, a letter of credit issued by a domestic U.S. bank, or securities issued or guaranteed by the U.S. Government having a value at all times not less than 100% of the value of the securities loaned, (ii) the borrower add to such collateral whenever the price of the securities loaned rises (i.e., the value of the loan is "marked to the market" on a daily basis), (iii) the loan be made subject to termination by the Trust at any time and (iv) the Trust receive reasonable interest on the loan (which may include the Trust's investing any cash collateral in interest bearing short-term investments), any distributions on the loaned securities and any increase in their market value. The Trust will not lend portfolio securities if, as a result, the aggregate of such loans exceeds 331/3% of the value of the Trust's total assets (including such loans). Loan arrangements made by the Trust will comply with all other applicable regulatory requirements, including the rules of the New York Stock Exchange, which rules presently require the borrower, after notice, to redeliver the securities within the normal settlement time of five business days. All relevant facts and circumstances, including the creditworthiness of the Qualified Institution, will be monitored by the Adviser, and will be considered in making decisions with respect to lending of securities, subject to review by the Trust's board of directors.

The Trust may pay reasonable negotiated fees in connection with loaned securities, so long as such fees are set forth in a written contract and approved by the Trust's board of directors. In addition, voting rights may pass with the loaned securities, but if a material event were to occur affecting such a loan, the loan must be called and the securities voted.

Zero Coupon Bonds. The Trust may invest in zero coupon bonds. A zero coupon bond is a bond that does not pay interest for its entire life. The market prices of zero coupon bonds are affected to a greater extent by changes in prevailing levels of interest rates and thereby tend to be more volatile in price than securities that pay interest periodically. In addition, because the Trust accrues income with respect to these securities prior to the receipt of such interest, it may have to dispose of portfolio securities under disadvantageous circumstances in order to obtain cash needed to pay income dividends in amounts necessary to avoid unfavorable tax consequences.

The Adviser is responsible for decisions to buy and sell securities for the Trust, the selection of brokers and dealers to effect the transactions and the negotiation of prices and any brokerage commissions. The securities in which the Trust invests are traded principally in the over-the-counter market. In the over-the-counter market, securities are generally traded on a "net" basis with dealers acting as principal for their own accounts without a stated commission, although price of the security usually includes a mark-up to the dealer. Securities purchased in underwritten offerings generally include, in the price, a fixed amount of compensation for the manager(s), underwriter(s) and dealer(s). The Trust may also purchase certain money market instruments directly from an issuer, in which case no commissions or discounts are paid. Purchases and sales of debt securities on a stock exchange are effected through brokers who charge a commission for their services.

The Adviser is responsible for effecting securities transactions of the Trust and will do so in a manner deemed fair and reasonable to shareholders of the Trust and not according to any formula. The Adviser's primary considerations in selecting the manner of executing securities transactions for the Trust will be prompt execution of orders, the size and breadth of the market for the security, the reliability, integrity and financial condition and execution capability of the firm, the size of the difficulty in executing the order, and the best net price. There are many instances when, in the judgment of the Adviser, more than one firm can offer comparable execution services. In selecting among such firms, consideration is given to those firms which supply research and other services in addition to execution services. Consideration may also be given to the sale of shares of the Trust. However, it is not the policy of the Adviser, absent special circumstances, to pay higher commissions to a firm because it has supplied such research or other services.

The Adviser is able to fulfill its obligations to furnish a continuous investment program to the Trust without receiving such information from brokers; however, it considers access to such information to be an important element of financial management. Although such information is considered useful, its value is not determinable, as it must be reviewed and assimilated by the Adviser, and does not reduce the Adviser's normal research activities in rendering investment advice. It is possible that the Adviser's expenses could be materially increased if it attempted to purchase this type of information or generate it through its own staff.

One or more of the other investment companies or accounts which the Adviser manages may own from time to time some of the same investments as the Trust. Investment decisions for the Trust are made independently from those of such other investment companies or accounts; however, from time to time, the same investment decision may be made for more than one company or account. When two or more companies or accounts seek to purchase or sell the same securities, the securities actually purchased or sold will be allocated among the companies and accounts on a good faith equitable basis by the Adviser in its discretion in accordance with the accounts' various investment objective. In some cases, this system may adversely affect the price or size of the position obtainable for the Trust. In other cases, however, the ability of the Trust to participate in volume transactions may produce better execution for the Trust. It is the opinion of the Trust's board of directors that this advantage, when combined with the other benefits available due to the Adviser's organization, outweighs any disadvantages that may be said to exist from exposure to simultaneous transactions.

Although the investment management agreement contains no restrictions on portfolio turnover, it is not the Trust's policy to engage in transactions with the objective of seeking profits from short-term trading. It is expected that the annual portfolio turnover rate of the Trust will be less than 200% excluding securities having a maturity of one year or less. Because it is difficult to predict accurately portfolio turnover rates, actual turnover may be higher or lower. Higher portfolio turnover results in increased Trust expenses, including brokerage commissions, dealer mark-ups and other transaction costs on the sale of securities and on the reinvestment in other securities.

ADDITIONAL INFORMATION CONCERNING
THE AUCTIONS FOR NEW PREFERRED SHARES

GENERAL

Auction Agency Agreement. The Trust will enter into an Auction Agency Agreement (the "Auction Agency Agreement") with the Auction Agent (currently, Deutsche Bank Group) which provides, among other things, that the Auction Agent will follow the Auction Procedures for purposes of determining the Applicable Rate for the New Preferred Shares so long as the Applicable Rate for such shares is to be based on the results of an Auction.

Broker-Dealer Agreements. Each Auction requires the participation of one or more Broker-Dealers. The Auction Agent will enter into agreements (collectively, the "Broker-Dealer Agreements") with several Broker-Dealers selected by the Trust, which provide for the participation of those Broker- Dealers in Auctions for New Preferred Shares. See "Broker-Dealers" below.

Securities Depository. The Depository Trust Company ("DTC") will act as the Securities Depository for the Agent Members with respect to the New Preferred Shares. One certificate for all of the New Preferred Shares will be registered in the name of Cede & Co., as nominee of the Securities Depository. Such certificate will bear a legend to the effect that such certificate is issued subject to the provisions restricting transfers of shares of New Preferred Shares contained in the Articles Supplementary. The Trust will also issue stop-transfer instructions to the transfer agent for New Preferred Shares. Prior to the commencement of the right of holders of preferred shares of the Trust to elect a majority of the Trust's directors, as described under "Description of New Preferred Shares-Voting Rights" in the prospectus, Cede & Co. will be the holder of record of all shares of the New Preferred Shares and owners of such shares will not be entitled to receive certificates representing their ownership interest in such shares.

DTC, a New York-chartered limited purpose trust company, performs services for its participants (including the Agent Members), some of whom (and/or their representatives) own DTC. DTC maintains lists of its participants and will maintain the positions (ownership interests) held by each such participant (the "Agent Member") in New Preferred Shares, whether for its own account or as a nominee for another person. Additional information concerning DTC and the DTC depository system is included as an Exhibit to the Registration Statement of which this statement of additional information forms a part.

CONCERNING THE AUCTION AGENT

The Auction Agent will act as agent for the Trust in connection with Auctions. In the absence of bad faith or negligence on its part, the Auction Agent will not be liable for any action taken, suffered, or omitted or for any error of judgment made by it in the performance of its duties under the Auction Agency Agreement and will not be liable for any error of judgment made in good faith unless the Auction Agent will have been negligent in ascertaining the pertinent facts.

The Auction Agent may rely upon, as evidence of the identities of the Existing Holders of New Preferred Shares, the Auction Agent's registry of Existing Holders, the results of Auctions and notices from any Broker-Dealer (or other Person, if permitted by the Trust) with respect to transfers described under "The Auction" in the prospectus and notices from the Trust. The Auction Agent is not required to accept any such notice for an Auction unless it is received by the Auction Agent by 3:00 p.m., New York City time, on the Business Day preceding such Auction.

The Auction Agent may terminate the Auction Agency Agreement upon notice to the Trust on a date no earlier than 60 days after such notice. If the Auction Agent should resign, the Trust will use its best efforts to enter into an agreement with a successor Auction Agent containing substantially the same terms and conditions as the Auction Agency Agreement. The Trust may remove the Auction Agent provided that prior to such removal the Trust shall have entered into such an agreement with a successor Auction Agent.

BROKER-DEALERS

The Auction Agent after each Auction for New Preferred Shares will pay to each Broker-Dealer, from funds provided by the Trust, a service charge at the annual rate of 0.25% in the case of any Auction immediately preceding a Dividend Period of less than one year, or a percentage agreed to by the Trust and the Broker-Dealers in the case of any Auction immediately preceding a Dividend Period of one year or longer, of the purchase price of shares of New Preferred Shares placed by such Broker-Dealer at such Auction. For the purposes of the preceding sentence, New Preferred Shares will be placed by a Broker-Dealer if such shares were
(a) the subject of Hold Orders deemed to have been submitted to the Auction Agent by the Broker-Dealer and were acquired by such Broker- Dealer for its own account or were acquired by such Broker-Dealer for its customers who are Beneficial Owners or (b) the subject of an Order submitted by such Broker-Dealer that is (i) a Submitted Bid of an Existing Holder that resulted in such Existing Holder continuing to hold such shares as a result of the Auction or (ii) a Submitted Bid of a Potential Holder that resulted in such Potential Holder purchasing such shares as a result of the Auction or (iii) a valid Hold Order. The Trust may request the Auction Agent to terminate one or more Broker-Dealer Agreements at any time, provided that at least one Broker-Dealer Agreement is in effect after such termination.

The Broker-Dealer Agreements provide that a Broker-Dealer (other than an affiliate of the Trust) may submit Orders in Auctions for its own account, unless the Trust notifies all Broker-Dealers that they may no longer do so, in which case Broker-Dealers may continue to submit Hold Orders and Sell Orders for their own accounts. Any Broker- Dealer that is an affiliate of the Trust may submit Orders in Auctions, but only if such Orders are not for its own account. If a Broker-Dealer submits an Order for its own account in any Auction, it might have an advantage over other Bidders because it would have knowledge of all Orders submitted by it in that Auction; such Broker-Dealer, however, would not have knowledge of Orders submitted by other Broker-Dealers in that Auction.

REPURCHASE OF COMMON SHARES

The Trust is a closed-end investment company and as such its common shareholders will not have the right to cause the Trust to redeem their shares. Instead, the Trust's common shares will trade in the open market at a price that will be a function of several factors, including dividend levels (which are in turn affected by expenses), net asset value, call protection, price, dividend stability, relative demand for and supply of such shares in the market, general market and economic conditions and other factors. Because shares of a closed-end investment company may frequently trade at prices lower than net asset value, the Trust's board of directors may consider action that might be taken to reduce or eliminate any material discount from net asset value in respect of common shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares at net asset value, or the conversion of the Trust to an open-end investment company. The board of directors may not decide to take any of these actions. In addition, there can be no assurance that share repurchases or tender offers, if undertaken, will reduce market discount.

Notwithstanding the foregoing, at any time when preferred shares of the Trust are outstanding, the Trust may not purchase, redeem or otherwise acquire any of its common shares unless (1) all accrued preferred shares dividends have been paid and (2) at the time of such purchase, redemption or acquisition, the net asset value of the Trust's portfolio (determined after deducting the acquisition price of the common shares) is at least 200% of the liquidation value of the outstanding preferred shares (expected to equal the original purchase price per share plus any accrued and unpaid dividends thereon). The staff of the SEC currently requires that any tender offer made by a closed-end investment company for its shares must be at a price equal to the net asset value of such shares on the close of business on the last day of the tender offer. Any service fees incurred in connection with any tender offer made by the Trust will be borne by the Trust and will not reduce the stated consideration to be paid to tendering shareholders.

Subject to its investment limitations, the Trust may borrow to finance the repurchase of common shares or to make a tender offer. Interest on any borrowings to finance share repurchase transactions or the accumulation of cash by the Trust in anticipation of share repurchases or tenders will reduce the Trust's net income. Any share repurchase, tender offer or borrowing that might be approved by the Trust's board of directors would have to comply with the Securities Exchange Act of 1934 and the 1940 Act and the rules and regulations under each of those acts.

Although the decision to take action in response to a discount from net asset value will be made by the board of directors at the time it considers such issue, it is the board's present policy, which may be changed by the board of directors, not to authorize repurchases of common shares or a tender offer for such shares if (1) such transactions, if consummated, would (a) result in the delisting of the common shares from the New York Stock Exchange, or (b) impair the Trust's status as a regulated investment company under the Internal Revenue Code of 1986 (which would make the Trust a taxable entity, causing the Trust's income to be taxed at the corporate level in addition to the taxation of shareholders who receive dividends from the Trust) or as a registered closed-end investment company under the 1940 Act; (2) the Trust would not be able to liquidate portfolio securities in an orderly manner and consistent with the Trust's investment objective and policies in order to repurchase shares; or
(3) there is, in the board's judgment, any (a) material legal action or proceeding instituted or threatened challenging such transactions or otherwise materially adversely affecting the Trust, (b) general suspension of or limitation on prices for trading securities on the New York Stock Exchange, (c) declaration of a banking moratorium by Federal or state authorities or any suspension of payment by United States banks in which the Trust invests, (d) material limitation affecting the Trust or the issuers of its portfolio securities by Federal or state authorities on the extension of credit by lending institutions or on the exchange of foreign currency, (e) commencement of war, armed hostilities or other international or national calamity directly or indirectly involving the United States, or
(f) other event or condition which would have a material adverse effect (including any adverse tax effect) on the Trust or its shareholders if shares were repurchased. The board of directors may in the future modify these conditions in light of experience.

The repurchase by the Trust of its common shares at prices below net asset value will result in an increase in the net asset value of those shares that remain outstanding. However, there can be no assurance that share repurchases or tenders at or below net asset value will result in the Trust's common shares trading at a price equal to their net asset value. Nevertheless, the fact that the Trust's shares may be the subject of repurchase or tender offers at net asset value from time to time, or that the Trust may be converted to an open-end company, may reduce any spread between market price and net asset value that might otherwise exist.

In addition, a purchase by the Trust of its common shares will decrease the Trust's total assets which would likely have the effect of increasing the Trust's expense ratio. Any purchase by the Trust of its common shares at a time when preferred shares are outstanding will increase the leverage applicable to the outstanding common shares then remaining and decrease the asset coverage of the preferred shares.

Before deciding whether to take any action if the common shares trade below net asset value, the Trust's board of directors would likely consider all relevant factors, including the extent and duration of the discount, the liquidity of the Trust's portfolio, the impact of any action that might be taken on the Trust or its shareholders and market considerations. Based on these considerations, even if the Trust's shares should trade at a discount, the board of directors may determine that, in the interest of the Trust and its shareholders, no action should be taken.

TAX MATTERS

The Trust has qualified and elected, and intends to continue to qualify under the Code, as a regulated investment company and to satisfy conditions which enable dividends on common shares or Preferred Shares which are attributable to interest on tax-exempt municipal securities to be exempt from Federal income tax in the hands of owners of such shares, subject to the possible application of the Federal alternative minimum tax.

To qualify for tax treatment as a regulated investment company, the Trust must, among other things: (a) distribute to its shareholders at least an amount equal to the sum of (i) 90% of its net investment income (which is its investment company taxable income as that term is defined in the Code but determined without regard to the deduction for dividends paid) and (ii) 90% of its net tax-exempt income and (b) diversify its holdings so that, at the end of each fiscal quarter of the Trust (i) at least 50% of the market value of the Trust's assets is represented by cash, cash items, U.S. government securities and securities of other regulated investment companies, and other securities, with these other securities limited, with respect to any one issuer, to an amount not greater in value than 5% of the Trust's total assets, and to not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the market value of the Trust's assets is invested in the securities of any one issuer (other than U.S. government securities or securities of other regulated investment companies). In meeting these requirements, the Trust may be restricted in the utilization of certain of the investment techniques described above and in the prospectus. If in any year the Trust should fail to qualify for tax treatment as a regulated investment company, the Trust would incur a regular Federal corporate income tax upon its taxable income for that year, and distributions to its shareholders would be taxable to such holders as ordinary income to the extent of the Trust's earnings and profits. A regulated investment company that fails to distribute, by the close of each calendar year, at least an amount equal to the sum of 98% of its ordinary taxable income for such year and 98% of its capital gain net income for the one year period ending October 31 in such year, plus any shortfalls from the prior year's required distribution, is liable for a 4% excise tax on the portion of the undistributed amount of such income that is less than the required amount for such distributions. To avoid the imposition of this excise tax, the Trust generally makes the required distributions of its ordinary taxable income, if any, and its capital gain net income, to the extent possible, by the close of each calendar year.

Certain of the Trust's investment practices are subject to special provisions of the Code that, among other things, may defer the use of certain deductions or losses of the Trust, affect the holding period of securities held by the Trust and alter the character of the gains or losses realized by the Trust. These provisions may also require the Trust to recognize income or gain without receiving cash with which to make distributions in the amounts necessary to satisfy the requirements for maintaining regulated investment company status and for avoiding income and excise taxes. The Trust will monitor its transactions and may make certain tax elections in order to mitigate the effect of these rules and prevent disqualification of the Trust as a regulated investment company.

The Trust intends to qualify to pay "exempt-interest" dividends, as defined in the Code on its common shares and Preferred Shares. In order for any distributions to owners of the Trust's Preferred Shares to be eligible to be treated as exempt-interest dividends, such Preferred Shares must be treated as stock for Federal income tax purposes. Under the Code, at the close of each quarter of its taxable year, if at least 50% of the value of its total assets consists of municipal bonds, the Trust will be qualified to pay exempt-interest dividends to its shareholders. Exempt-interest dividends are dividends or any part thereof (other than a capital gain dividend) paid by the Trust which are attributable to interest on municipal bonds and are so designated by the Trust within 60 days of the Trust's fiscal year-end. Exempt-interest dividends will be exempt from Federal income tax, subject to the possible application of the Federal alternative minimum tax. Insurance proceeds received by the Trust under any insurance policies in respect of scheduled interest payments on defaulted municipal bonds, as described herein, will generally be excludable from gross income under Section 103(a) of the Code. In the case of non-appropriation by a political subdivision, however, there can be no assurance that payments made by the issuer representing interest on such "non-appropriation" municipal lease obligations will be excludable from gross income for Federal income tax purposes. See "Investment Objective and Policies" above. Gains of the Trust that are attributable to market discount on certain municipal obligations acquired after April 30, 1993 are treated as ordinary income. The interest on private activity bonds in most instances is not Federally tax-exempt to a person who is a "substantial user" of a facility financed by such bonds or a "related person" of such "substantial user." As a result, the Trust may not be an appropriate investment for shareholders who are considered either a "substantial user" or a "related person" within the meaning of the Code. In general, a "substantial user" of a facility includes a "non- exempt person who regularly uses a part of such facility in his trade or business." "Related persons" are in general defined to include persons among whom there exists a relationship, either by family or business, which would result in a disallowance of losses in transactions among them under various provisions of the Code (or if they are members of the same controlled group of corporations under the Code), including a partnership and each of its partners (and certain members of their families), an S corporation and each of its shareholders (and certain members of their families) and various combinations of these and other relationships. The foregoing is not a complete description of all of the provisions of the Code covering the definitions of "substantial user" and "related person." The Code provides that every holder of Preferred Shares required to file a tax return must include for information purposes on such return the amount of tax-exempt interest received during the taxable year, including any exempt-interest dividends received from the Trust.

Federal tax law imposes an alternative minimum tax with respect to both corporations and individuals. Interest on certain municipal obligations, such as bonds issued to make loans for housing purposes or to private entities (but not to certain tax-exempt organizations such as universities and non-profit hospitals) is included as an item of tax preference in determining the amount of a taxpayer's alternative minimum taxable income. To the extent that the Trust receives income from municipal obligations subject to the Federal alternative minimum tax, a portion of the dividends paid by it, although otherwise exempt from Federal income tax, will be taxable to its shareholders to the extent that their tax liability is determined under the alternative minimum tax. The Trust will annually supply a report indicating the percentage of the Trust's income attributable to municipal obligations subject to the Federal alternative minimum tax. In addition, for certain corporations, alternative minimum taxable income is increased by 75% of the difference between an alternative measure of income ("adjusted current earnings") and the amount otherwise determined to be the alternative minimum taxable income. Interest on all municipal obligations, and therefore all distributions by the Trust that would otherwise be tax-exempt, is included in calculating a corporation's adjusted current earnings. Certain small corporations are not subject to the alternative minimum tax.

Tax-exempt income, including exempt-interest dividends paid by the Trust, is taken into account in calculating the amount of social security and railroad retirement benefits that may be subject to Federal income tax.

Distributions to shareholders by the Trust of net income received, if any, from taxable temporary investments and net short-term capital gains, if any, realized by the Trust will be taxable to its shareholders as ordinary income. Distributions by the Trust of net capital gain (which is the excess of net long-term capital gain over net short-term capital loss), if any, are taxable as long-term capital gain, regardless of the length of time the shareholder has owned common shares or Preferred Shares. The amount of taxable income allocable to the Trust's Preferred Shares will depend upon the amount of such income realized by the Trust, but is not generally expected to be significant. Except for dividends paid on Preferred Shares which include an allocable portion of any net capital gain or other taxable income, the Trust anticipates that all dividends paid on shares of its Preferred Shares will constitute exempt-interest dividends for Federal income tax purposes. Distributions, if any, in excess of the Trust's earnings and profits will first reduce the adjusted tax basis of a shareholder's shares and, after that basis has been reduced to zero, will constitute capital gains to the shareholder (assuming the shares are held as a capital asset). As long as the Trust qualifies as a regulated investment company under the Code, no part of its distributions to shareholders will qualify for the dividends-received deduction for corporations.

The Internal Revenue Service (the "IRS") requires that a regulated investment company that has two or more classes of shares designate to each such class proportionate amounts of each type of its income for each tax year based upon the percentage of total dividends distributed to each class for such year. The Trust intends each year to allocate, to the fullest extent practicable, net tax-exempt interest, net capital gain and other taxable income, if any, between its common shares and preferred shares, including the Preferred Shares, in proportion to the total dividends paid to each class with respect to such year. To the extent permitted under applicable law, the Trust reserves the right to make special allocations of income within a class, consistent with the objective of the Trust. The Trust may, at its election, notify the Auction Agent of the amount of any net capital gain or other income taxable for Federal income tax purposes to be included in any dividend on shares of its Preferred Shares prior to the Auction establishing the Applicable Rate for such dividend. If the Trust allocates any net capital gain or other taxable income for Federal income tax purposes to its Preferred Shares without having given advance notice thereof as described above, the Trust generally will be required to make payments to owners of its Preferred Shares to which such allocation was made in order to offset the Federal income tax effect of the taxable income so allocated as described under "Description of Preferred Shares-Dividends and Dividend Periods-Additional Dividends" in the prospectus.

Although dividends generally will be treated as distributed when paid, dividends declared in October, November or December, payable to shareholders of record on a specified date in one of those months and paid during the following January will be treated as having been distributed by the Trust (and received by the shareholders) on December 31 of the year declared.

If at any time when the Trust's Preferred Shares are outstanding the Trust fails to meet the Preferred Shares Basic Maintenance Amount or the 1940 Act Preferred Shares Asset Coverage, the Trust will be required to suspend distributions to holders of its common shares until such maintenance amount or asset coverage, as the case may be, is restored. See "Description of New Preferred Shares-Dividends and Dividend Periods" in the prospectus. This may prevent the Trust from distributing at least an amount equal to the sum of 90% of its investment company taxable income and 90% of its net tax-exempt interest income, and may therefore jeopardize the Trust's qualification for taxation as a regulated investment company or cause the Trust to incur a tax liability or a non-deductible 4% excise tax on the undistributed taxable income (including gain), or both. Upon failure to meet the Preferred Shares Basic Maintenance Amount or the 1940 Act Preferred Shares Asset Coverage, the Trust will be required to redeem its shares of Preferred Shares in order to maintain or restore such maintenance amount or asset coverage and avoid the adverse consequences to the Trust and its shareholders of failing to qualify as a regulated investment company. There can be no assurance, however, that any such redemption would achieve such objective.

The Trust may, at its option, redeem its Preferred Shares in whole or in part, and is required to redeem Preferred Shares to the extent required to maintain the Preferred Shares Basic Maintenance Amount and the 1940 Act Preferred Shares Asset Coverage. Gain or loss, if any, resulting from a redemption of Preferred Shares will be taxed as gain or loss from the sale or exchange of Preferred Shares under Section 302 of the Code rather than as a dividend, but only if the redemption distribution (a) is deemed not to be essentially equivalent to a dividend, (b) is in complete redemption of an owner's interest in the Trust, (c) is substantially disproportionate with respect to the owner, or (d) with respect to a non- corporate owner, is in partial liquidation of the owner's interest in the Trust. For purposes of (a), (b) and (c) above, a shareholder's ownership of common shares will be taken into account.

The sale or other disposition of common shares or Preferred Shares of the Trust will normally result in capital gain or loss to shareholders. Present law taxes both long-term and short-term capital gains of corporations at the rates applicable to ordinary income. For non-corporate taxpayers, however, under current law short-term capital gains and ordinary income will be taxed at a maximum rate of 39.6% while long-term capital gains generally will be taxed at a maximum rate of 20%. However, because of the limitations on itemized deductions and the deduction for personal exemptions applicable to higher income taxpayers, the effective rate of tax may be higher in certain circumstances. Losses realized by a shareholder on the sale or exchange of shares of the Trust held for six months or less are disallowed to the extent of any distribution of exempt- interest dividends received with respect to such shares, and, if not disallowed, such losses are treated as long-term capital losses to the extent of any distribution of net capital gain received with respect to such shares. A shareholder's holding period is suspended for any periods during which the shareholder's risk of loss is diminished as a result of holding one or more other positions in substantially similar or related property, or through certain options or short sales. Any loss realized on a sale or exchange of shares of the Trust will be disallowed to the extent those shares of the Trust are replaced by other shares within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the original shares. In that event, the basis of the replacement shares of the Trust will be adjusted to reflect the disallowed loss.

The Code provides that interest on indebtedness incurred or continued to purchase or carry the Trust's shares to which exempt-interest dividends are allocated is not deductible. Under rules used by the IRS for determining when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase or ownership of shares may be considered to have been made with borrowed funds even though such funds are not directly used for the purchase or ownership of such shares.

Nonresident alien individuals and certain foreign corporations and other entities ("foreign investors") generally are subject to U.S. withholding tax at the rate of 30% (or possibly a lower rate provided by an applicable tax treaty) on distributions of net investment income (which includes net short-term capital gain). To the extent received by foreign investors, exempt-interest dividends, distributions of net capital gain and gain from the sale or other disposition of Preferred Shares generally are exempt from United States Federal income taxation. Different tax consequences may result if the owner is engaged in a trade or business in the United States or, in the case of an individual, is present in the United States for 183 or more days during a taxable year.

The Trust is required in certain circumstances to backup withhold 31% of taxable dividends and certain other payments paid to non-corporate holders of the Trust's shares who do not furnish to the Trust their correct taxpayer identification number (in the case of individuals, their social security number) and certain certifications, or who are otherwise subject to backup withholding. Backup withholding is not an additional tax. Any amounts withheld from payments made to a shareholder may be refunded or credited against such shareholder's United States Federal income tax liability, if any, provided that the required information is furnished to the IRS.

The foregoing is a general, summary of the provisions of the Code and regulations thereunder presently in effect as they directly govern the taxation of the Trust and its shareholders. These provisions are subject to change by legislative or administrative action, and any such change may be retroactive. Moreover, the foregoing does not address many of the factors that may be determinative of whether an investor will be liable for the alternative minimum tax. Shareholders are advised to consult their own tax advisers for more detailed information concerning the Federal income tax consequences of purchasing, holding and disposing of Trust shares.

APPENDIX A

GENERAL CHARACTERISTICS AND
RISKS OF HEDGING TRANSACTIONS

In order to hedge against changes in the value of its portfolio securities, the Trust may from time to time engage in certain hedging strategies. The Trust will engage in such activities from time to time in the Adviser's discretion, and may not necessarily be engaging in such activities when movements in interest rates that could affect the value of the assets of the Trust occur. The Trust's ability to pursue certain of these strategies may be limited by the Commodity Exchange Act, applicable regulations of the Commodity Futures Trading Commission ("CFTC") and the federal income tax requirements applicable to regulated investment companies.

PUT AND CALL OPTIONS ON SECURITIES AND INDICES

The Trust may purchase and sell put and call options on securities and financial indices. A put option gives the purchaser of the option the right to sell and the seller the obligation to buy the underlying security at the exercise price during the option period. Index options are similar to options on securities except that, rather than taking or making delivery of securities underlying the option at a specified price upon exercise, an index option gives the holder the right to receive cash upon exercise of the option if the level of the index upon which the option is based is greater, in the case of a call, or less, in the case of a put, than the exercise price of the option. The purchase of a put option on a debt security would be designed to protect the Trust's holdings in a security against a substantial decline in the market value. A call option gives the purchaser of the option the right to buy and the seller the obligation to sell the underlying security at the exercise price during the option period. The purchase of a call option on a security would be intended to protect the Trust against an increase in the price of a security that it intended to purchase in the future. In the case of either put or call options that it has purchased, if the option expires without being sold or exercised, the Trust will experience a loss in the amount of the option premium plus any related commissions. When the Trust sells put and call options, it receives a premium as the seller of the option. The premium that the Trust receives for selling the option will serve as a partial hedge, in the amount of the option premium, against changes in the value of the securities in its portfolio. During the term of the option, however, a covered call seller has, in return for the premium on the option, given up the opportunity for capital appreciation above the exercise price of the option if the value of the underlying security increases, but has retained the risk of loss should the price of the underlying security decline. Conversely, a secured put seller retains the risk of loss should the market value of the underlying security decline below the exercise price of the option, less the premium received on the sale of the option. The Trust is authorized to purchase and sell exchange listed options and over-the-counter options ("OTC Options") which are privately negotiated with the counterparty to such contract. Listed options are issued by the Options Clearing Corporation ("OCC"), which guarantees the performance of the obligations of the parties to such options. All put and call options written by the Trust will be covered.

The Trust's ability to close out its position as a purchaser or seller of an exchange-listed put or call option is dependent upon the existence of a liquid secondary market. Among the possible reasons for the absence of a liquid secondary market on an exchange are: (i) insufficient trading interest in certain options; (ii) restrictions on transactions imposed by an exchange; (iii) trading halts, suspensions or other restrictions imposed with respect to particular classes or series of options or underlying securities; (iv) interruption of the normal operations on an exchange; (v) inadequacy of the facilities of an exchange or OCC to handle current trading volume; or (vi) a decision by one or more exchanges to discontinue the trading of options (or a particular class or series of options), in which event the secondary market on that exchange (or in that class or series of options) would cease to exist, although outstanding options on that exchange that had been listed by the OCC as a result of trades on that exchange would generally continue to be exercisable in accordance with their terms. OTC options are purchased from or sold to dealers, financial institutions or other counterparties which have entered into direct agreements with the Trust. With OTC Options, such variables as expiration date, exercise price and premium will be agreed upon between the Trust and the counterparty, without the intermediation of a third party such as the OCC. If the counterparty fails to make or take delivery of the securities underlying an option it has written, or otherwise settle the transaction in accordance with the terms of that option as written, the Trust would lose the premium paid for the option as well as any anticipated benefit of the transaction. As the Trust must rely on the credit quality of the counterparty rather than the guarantee of the OCC, it will only enter into OTC Options with counterparties with the highest long-term credit ratings, and with primary U.S. Government securities dealers recognized by the Federal Reserve Bank in New York.

The hours of trading for options on debt securities may not conform to the hours during which the underlying securities are traded. To the extent that the option markets close before the markets for the underlying securities, significant price and rate movements can take place in the underlying markets that cannot be reflected in the option markets.

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

Characteristics. The Trust may purchase and sell futures contracts and purchase put and call options on such futures contracts traded on recognized domestic exchanges as a hedge against anticipated interest rate changes or other market movements and future risk management. The sale of a futures contract creates an obligation by the Trust, as seller, to deliver the specific type of financial instrument called for in the contract at a specified future time for a specified price. Options on futures contracts are similar to options on securities except that an option on a futures contract gives the purchaser the right in return for the premium paid to assume a position in a futures contract (a long position if the option is a call and a short position if the option is a put).

Margin Requirements. At the time a futures contract is purchased or sold, the Trust must allocate cash or securities as a deposit payment ("initial margin"). It is expected that the initial margin that the Trust will pay may range from approximately 1% to approximately 5% of the value of the instruments underlying the contract. In certain circumstances, however, such as periods of high volatility, the Trust may be required by an exchange to increase the level of its initial margin payment Additionally, initial margin requirements may be increased in the future pursuant to regulatory action. An outstanding futures contract is valued daily and the payment in cash of "variation margin" may be required, a process known as "marking to the market." Transactions in listed options and futures are usually settled by entering into an offsetting transaction, and are subject to the risk that this position may not be able to be closed if no offsetting transaction can be arranged.

Limitations on Use of Futures Contracts and Options on Futures Contracts. The Trust's use of futures contracts and options on futures contracts will in all cases be consistent with applicable regulatory requirements and in particular, the rules and regulations of the CFTC and will be entered into only for bona fide hedging purposes or other appropriate risk management and duration management or other appropriate portfolio strategies. In addition, the Trust may not sell futures contracts if the value of such futures contracts exceeds the total market value of the Trust's portfolio securities.

The Trust will not engage in transactions in futures contracts or options thereon for speculative purposes but only as a hedge against changes resulting from market conditions in the values of securities in its portfolio. In addition, the Trust will not enter into a futures contract or option thereon if, immediately thereafter, the sum of the amount of its initial deposits and premiums on open contracts and options would exceed 5% of the Trust's total assets (taken at current value); provided, however, that in the case of an option that is in-the-money at the time of the purchase, the in-the- money amount may be excluded in calculating the 5% limitation. Also, when required, a segregated account of cash or cash equivalents will be maintained and marked to market in an amount equal to the market value of the contract. The Adviser reserves the right to comply with such different standards as may be established from time to time by CFTC rules and regulations with respect to the purchase and sale of futures contracts and options thereon.

Segregation and Cover Requirements. Futures contracts, interest rate swaps, caps, floors and collars, and options on securities, indices and futures contracts sold by the Trust are generally subject to segregation and coverage requirements established by either the CFTC or the SEC, with the result that, if the Trust does not hold the instrument underlying the futures contract or option, the Trust will be required to segregate on an ongoing basis with its custodian, cash, U.S. Government securities, or other liquid high grade debt obligations in an amount at least equal to the Trust's obligations with respect to such instruments. Such amounts will fluctuate as the market value of the obligations increases or decreases. The segregation requirement can result in the Trust maintaining positions it would otherwise liquidate and consequently segregating assets with respect thereto at a time when it might be disadvantageous to do so.

Hedging Transactions present certain risks. In particular, the variable degree of correlation between price movements of hedging instruments and price movements in the position being hedged creates the possibility that losses on the hedge may be greater than gains in the value of the Trust's positions. In addition, certain hedging instruments and markets may not be liquid in all circumstances. As a result, in volatile markets, the Trust may not be able to close out a transaction in certain of these instruments without incurring losses substantially greater than the initial deposit. Although the contemplated use of these instruments should tend to minimize the risk of loss due to a decline in the value of the hedged position, at the same time they tend to limit any potential gain which might result from an increase in the value of such position. The ability of the Trust to hedge successfully will depend on the Adviser's ability to predict pertinent market movements, which cannot be assured. Finally, the daily variation margin deposit requirements in futures contracts that the Trust has sold create an ongoing greater potential financial risk than do options transactions, where the exposure is limited to the cost of the initial premium and transaction costs paid by the Trust. Losses due to Hedging Transactions will reduce net asset value.

The Trust's use of Hedging Transactions may be limited or affected by certain provisions of the Code and rating agency guidelines.

* Moody's rating. ** Municipal obligations not rated by Moody's but rated BBB-, BBB or BBB+ by S&P.

; provided, however, in the event a Moody's Discount Factor applicable to a Municipal Obligation is determined by reference to an insurance claims-paying ability rating in accordance with clause (i)(B), such Moody's Discount Factor shall be increased by an amount equal to 50% of the difference between (a) the percentage set forth in the foregoing table under the applicable rating category and (b) the percentage set forth in the foregoing table under the rating category which is one category lower than the applicable rating category. If a Municipal Obligation is covered by a Portfolio Insurance policy which provides the Trust with an option to obtain Permanent Insurance with respect to such Municipal Obligations and such Portfolio Insurance policy has been approved in writing by Moody's, the Moody's Discount Factor rating category shall be determined by averaging the insurance claims paying ability rating of the Portfolio Insurance provider and the next lowest rating category.

Notwithstanding the foregoing, (i) the Moody's Discount Factor for short-term Municipal Obligations will be 115% so long as such Municipal Obligations are rated at least MIG-1, VMIG-1 or P-1 by Moody's or 125% if such Obligations are not rated by Moody's but are rated A-1+ or SP-1+ or AA by S&P and mature or have a demand feature at par exercisable in 30 days or less, and (ii) no Moody's Discount Factor will be applied to cash or to Municipal Receivables (except to the extent provided in the definition thereof).

"Moody's Eligible Asset" means cash, a Municipal Receivable or a Municipal Obligation that (i) pays interest in cash, (ii) is publicly rated Baa or higher by Moody's or, if not rated by Moody's but rated by S&P, is rated at least BBB by S&P (provided that, for purposes of determining the Moody's Discount Factor applicable to any such S&P-rated Municipal Obligation, such Municipal Obligation (excluding any short-term Municipal Obligation) will be deemed to have a Moody's rating which is one full rating category lower than its S&P rating), (iii) does not have its Moody's rating suspended by Moody's and (iv) is part of an issue of Municipal Obligations of at least $10,000,000. Municipal Obligations issued by any one issuer, not rated by Moody's and rated BBB by S&P may comprise no more than 4% of total Municipal Obligations which are Moody's Eligible Assets; such BBB rated Municipal Obligations, if any, together with any Municipal Obligations issued by the same issuer and rated Baa by Moody's or A by S&P, may comprise no more than 6% of total Municipal Obligations which are Moody's Eligible Assets; such BBB, A and Baa rated Municipal Obligations, if any, together with any Municipal Obligations issued by the same issuer and rated A by Moody's or AA by S&P, may comprise no more than 10% of total Municipal Obligations which are Moody's Eligible Assets; and such BBB, Baa, A and AA rated Municipal Obligations, if any, together with any Municipal Obligations issued by the same issuer and rated Aa by Moody's or AAA by S&P, may comprise no more than 20% of total Municipal Obligations which are Moody's Eligible Assets. Municipal Obligations issued by issuers located within a single state or territory, not rated by Moody's and rated BBB by S&P, may comprise no more than 12% of total Municipal Obligations which are Moody's Eligible Assets; such BBB rated Municipal Obligations, if any, together with any Municipal Obligations issued by issuers located within the same state or territory and rated Baa by Moody's or A by S&P, may comprise no more than 20% of total Municipal Obligations which are Moody's Eligible Assets; such BBB, Baa and A rated Municipal Obligations, if any, together with any Municipal Obligations issued by issuers located within the same state or territory and rated A by Moody's or AA by S&P, may comprise no more than 40% of total Municipal Obligations which are Moody's Eligible Assets; and such BBB, Baa, A and AA rated Municipal Obligations issued by issuers located within the same state or territory and rated Aa by Moody's or AAA by S&P, may comprise no more than 60% of total Municipal Obligations which are Moody's Eligible Assets. Additionally, Municipal Obligations whose ratings are determined by the claims paying ability ratings of the providers of Portfolio Insurance may comprise no more than 10% of the total Municipal Obligations which are Moody's Eligible Assets. When the Corporation sells a Municipal Obligation and agrees to repurchase it at a future date, the Corporation must count as a liability for the purposes of the Preferred Shares Basic Maintenance Amount the amount of the repurchase price of such Municipal Obligation and such Municipal Obligation is considered a Moody's Eligible Asset to the extent it satisfies Moody's current guidelines. When the Corporation buys a Municipal Obligation and agrees to sell it to another party at a future date and the long-term debt of such other party is rated at least A2 and the transaction has a term of 30 days or less, the cash to be received by the Corporation will be counted as a Moody's Eligible Asset; otherwise such Municipal Obligation will be counted as a Moody's Eligible Asset to the extent it satisfies Moody's current guidelines.

The adjustments contemplated by the preceding sentence shall be made effective upon the time the Corporation receives the written notice from Moody's S&P and any Substitute Rating Agency contemplated by clause (ii) of the preceding sentence.

2. Dividends. (a) The Holders shall be entitled to receive, when, as and if declared by the Board of Directors of the Corporation, out of funds legally available therefor, cumulative dividends each consisting of
(i) cash at the Applicable Rate and (ii) an uncertificated Right to receive cash as set forth in paragraph 2(e) below, and no more, payable on the respective dates set forth below. Dividends on the Preferred Shares so declared and payable shall be paid (i) in preference to and in priority over any dividends declared and payable on the Common Stock, and (ii) to the extent permitted by law and to the extent available, out of net tax-exempt income earned on the Corporation's investments. To the extent permitted by law, dividends on Preferred Shares will be designated as exempt interest dividends. For the purposes of this section, the term "net tax-exempt income" shall exclude capital gains and other taxable income of the Corporation.

(b) (i) Cash dividends on Preferred Shares shall accumulate from the Date of Original Issue. With respect to the Series T7 Preferred Shares and Series T28 Preferred Shares, dividends will be payable commencing on the Initial Dividend Payment Date with respect to each series of Preferred Shares. Following the Initial Dividend Payment Date for the Series T7 Preferred Shares and Series T28 Preferred Shares, dividends on the Preferred Shares will be payable, at the option of the Corporation,
(ii) with respect to any Dividend Period of 35 or fewer days on the day next succeeding the last day thereof, (iii) with respect to any Dividend Period of more than 35 and fewer that 92 days, on the day next succeeding each period of 30 days to occur during such Dividend Period (or in the case of any Dividend Period of more than 91 days as specified in the relevant Notice of Special Dividend Period), and on the day next succeeding the last day thereof, (iv) with respect to any Dividend Period of 365 days or more, monthly on the first day of each calendar month during such Dividend Period (or in the case of any Dividend Period of more than 91 days, as specified in the relevant Notice of Special Dividend Period), and on the day next succeeding the last day thereof (each such date referred to in clauses (i),
(ii), (iii) and (iv) being hereinafter referred to as a "Normal Dividend Payment Date"), except that (i) if such Normal Dividend Payment Date is not a Business Day, then the Dividend Payment Date shall be the next succeeding date if both such dates following the Normal Dividend Payment Date are Business Days, or (ii) if the date following such Normal Dividend Payment Date is not a Business Day, then the Dividend Payment Date will be the date next preceding such Normal Dividend Payment Date if both such date and such Normal Dividend Payment Date are Business Days or (iii) if such Normal Dividend Payment Date and either the preceding date or the succeeding date are not Business Days, then the Dividend Payment Date shall be the first Business Day next preceding such Normal Dividend Payment Date that is next succeeded by a Business Day. If, however, the Securities Depository shall make available to its participants and members in funds immediately available in New York City on Dividend Payment Dates, the amount due as dividends on such Dividend Payment Dates (and the Securities Depository shall have so advised the Corporation), and if the day that otherwise would be the Dividend Payment Date is not a Business Day, then the Dividend Payment Date shall be the next succeeding Business Day. Although any particular Dividend Payment Date may not occur on a Normal Dividend Payment Date because of the exceptions discussed above, the next succeeding Dividend Payment Date shall be, subject to such provisos, the next Normal Dividend Payment Date. If for any reason a Dividend Payment Date cannot be fixed as described above, then the Board of Directors shall fix the Dividend Payment Date. Each dividend payment date determined as provided above is hereinafter referred to as a "Dividend Payment Date."

(ii) Each dividend shall be paid to the Holders as they appear in the Stock Register as of 12:00 Noon, New York City time, on the Business Day preceding the Dividend Payment Date. Dividends in arrears for any past Dividend Period may be declared and paid at any time, without reference to any regular Dividend Payment Date, to the Holders as they appear on the Stock Register on a date, not exceeding 15 days prior to the payment date therefor, as may be fixed by the Board of Directors of the Corporation.

(c) (i) during the period from and including the Date of Original Issue to but with respect to the Series T7 Preferred Shares and Series T28 Preferred Shares, excluding the Initial Dividend Payment Date (the "Initial Dividend Period"), the Applicable Rate shall be the Initial Dividend Rate. Commencing on the Initial Dividend Payment Date, with respect to the Series T7 Preferred Shares and Series T28 Preferred Shares, the Applicable Rate for each subsequent Dividend Period or portion thereof (hereinafter referred to as a "Subsequent Dividend Payment Period"), which Subsequent Dividend Payment Period shall commence on a Dividend Payment Date and shall end on the calendar day prior to the next Dividend Payment Date, shall be equal to the lesser of (x) the Maximum Applicable Rate for such Dividend Period or for such Subsequent Dividend Payment Period included herein or (y) the greater of (i) the Minimum Applicable Rate for such Dividend Period or for such Subsequent Dividend Payment Period included therein or (ii) the rate per annum that results for such Dividend Period or Subsequent Dividend Payment Period included therein from implementation of the Auction Procedures including any periodic application of a Spread to a specified Reference Index or Reference Security.

Notwithstanding the foregoing sentence, the Applicable Rate for each Dividend Period commencing during a Non-Payment Period shall be equal to the Non-Payment Period Rate and each Dividend Payment Period for Preferred Shares of any series, commencing after the first day of, and during, a Non-Payment Period shall be a 28-day Dividend Payment period (in the case of the Series T28 Preferred Shares) or a 7-day Dividend Payment Period (in the case of the Series T7 Preferred Shares). Except in the case of the willful failure of the Corporation to pay a dividend on a Dividend Payment Date or to redeem any Preferred Shares on the date set for such redemption, any amount of any dividend due on any Dividend Payment Date, the Corporation has declared such dividend payable on such Dividend Payment Date to the Holders of such Preferred Shares as of 12:00 noon, New York City time, on the Business Day preceding such Dividend Payment Date) or redemption price with respect to any Preferred Shares not paid to such Holders when due may be paid to such Holders in the same form of funds by 12:00 noon, New York City time, on any of the first three Business Days after such Dividend Payment Date or due date, as the case may be, provided that, such amount is accompanied by a late charge calculated for such period of non-payment at the Non-Payment Period Rate applied to the amount of such non-payment based on the actual number of days comprising such period divided by 365. In the case of a willful failure of the corporation to pay a dividend on a Dividend Payment Date or to redeem any Preferred Shares on the date set for such redemption, the preceding sentence shall not apply and the Applicable Dividend Rate for the Dividend Period commencing during the Non-Payment Period resulting from such failure shall be the Non-Payment Period Rate. For the purposes of the foregoing, payment to a person in same-day funds on any Business Day at any time shall be considered equivalent to payment to such person in New York Clearing House (next-day) funds at the same time on the preceding Business Day, and any payment made after 12:00 noon, New York City time, on any Business Day shall be considered to have been made instead in the same form of funds and to the same person before 12:00 noon, New York City time, on the next Business Day.

(ii) The amount of cash dividends per share of Preferred Shares payable (if declared) for any Dividend Payment Period or part thereof shall be computed by multiplying the Applicable Rate for such Dividend Payment Period by a fraction, the numerator of which shall be the number of days in such Dividend Payment Period or part thereof such share was outstanding and the denominator of which shall be 365 (or 360 for a Dividend Period of 365 days or more), multiplying the amount so obtained by $50,000 and rounding the amount so obtained to the nearest cent.

(iii) With respect to each Dividend Period that the Corporation desires to be a Special Dividend Period, the Corporation may, at its sole option and to the extent permitted by law, by telephonic and written notice (a "Request for Special Dividend Period") to the Auction Agent and to each Broker-Dealer, request that the next succeeding Dividend Period for such series of Preferred Shares be a number of days (other than 28 in the case of Series T28 Preferred Shares or 7 in the case of Series T7 Preferred Shares), evenly divisible by seven and specified in such notice, provided that for any Auction occurring after the initial Auction, the Corporation may not give a Request for Special Dividend Period (and any such request shall be null and void) unless Sufficient Clearing Bids were made in the last occurring Auction and unless full cumulative dividends, any amounts due with respect to mandatory redemptions, and any Additional Dividends payable prior to such date have been paid in full. Such Request for Special Dividend Period, in the case of a Dividend Period of 182 days or less, shall be given on or prior to the 4th day but not more than 7 days prior to an Auction Date for the Preferred Shares and, in the case of a Dividend Period of more than 182 days, shall be given on or prior to the 14th day but not more than 28 days prior to an Auction Date for the Preferred Shares. Such Request for Special Dividend Period shall also specify any proposed Bid Requirements. Upon receiving such Request for Special Dividend Period, the Broker-Dealer(s) shall jointly determine whether, given the factors set forth below, it is advisable that the Corporation issue a Notice of Special Dividend Period for the Preferred Shares as contemplated by such Request for Special Dividend Period and, if advisable, the Specific Redemption Provisions and shall give the Corporation and the Auction Agent written notice (a "Response") of such determination by no later than the third day prior to such Auction Date. In making such determination the Broker-Dealer(s) will consider (1) existing short-term and long-term market rates and indices of such short-term and long-term rates, (2) existing market supply and demand for short-term and long-term securities, (3) existing yield curves for short-term and long-term securities comparable to the Preferred Shares, (4) industry and financial conditions which may affect the Preferred Shares, (5) the investment objective of the Corporation and (6) the Dividend Periods and dividend rates at which current and potential beneficial holders of the Preferred Shares would remain or become beneficial holders. If none of the Broker-Dealer(s) give the Corporation and the Auction Agent a Response by such third day or if the Response of all of the Broker-Dealers providing a Response states that given the factors set forth above it is not advisable that the Corporation give a notice of Special Dividend Period for the Preferred Shares, the Corporation may not give a Notice of Special Dividend Period in respect of such Request for Special Dividend Period. In the event the Response of at least one Broker- Dealer does not indicate that it is not advisable that the Corporation give a notice of Special Dividend Period for the Preferred Shares, the Corporation may by no later than the second day prior to such Auction Date give a notice (a "Notice of Special Dividend Period") to the Auction Agent, the Securities Depository and each Broker-Dealer which notice will specify the duration of the Special Dividend Period, the Bid Requirements (if any) applicable to the Auction relating to such Special Dividend Period and Specific Redemption Provisions (if any). The Corporation shall not give a Notice of Special Dividend Period or convert to a Special Dividend Period and, if the Corporation has given a notice of Special Dividend, the Corporation is required to give telephonic and written notice of revocation (a "Notice of Revocation") to the Auction Agent, each Broker- Dealer, and the Securities Depository on or prior to the Business Day prior to the relevant Auction Date if it has not obtained the advice in writing of Moody's and S&P or any Substitute Rating Agency that the proposed Special Dividend Period will not adversely affect their then-current rating on the Preferred Shares or if (w) either the 1940 Act Preferred Shares Asset Coverage is not satisfied or the Corporation shall fail to maintain S&P Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount, in each case on each of the two Valuation Dates immediately preceding the Business Day prior to the relevant Auction Date (and in each case, with respect to Moody's Eligible Assets, using a Moody's Exposure Period equivalent to 14 days longer than normal) on an actual basis and on a pro forma basis giving effect to the proposed Special Dividend Period (using as a pro forma dividend rate with respect to such Special Dividend Period the dividend rate which the Broker Dealers shall advise the Corporation is an approximately equal rate for securities similar to the Preferred Shares with an equal frequency of recalculation of the Reference Index or Reference Security as is utilized by the Corporation with respect to the first Dividend Payment Period within such Special Dividend Period and using as a pro forma Maximum Applicable Rate the highest rate specified in the Notice of Special Dividend Period for the Dividend Payment Periods covering not less than the first 49 days of such proposed Special Dividend Period or, if no such rate is specified in the Notice of Special Dividend Period, the Maximum Applicable Rate resulting by operation of the definition of Special Dividend Period Reference Rate for the Special Dividend Period specified in such Notice of Special Dividend Period), (x) sufficient funds for the payment of dividends payable on the immediately succeeding Dividend Payment Date have not been irrevocably deposited with the Auction Agent by the close of business on third Business Day preceding the related Auction Date, (y) the Broker-Dealer(s) jointly advise the Corporation that after consideration of the factors listed above they have concluded that it is advisable to give a Notice of Revocation or
(z) the Corporation has determined to terminate the Special Dividend Period for any reason. If the Corporation is prohibited from giving a Notice of Special Dividend Period as a result of any of the factors enumerated in clause (w), (x), (y) or (z) of the prior sentence or if the Corporation gives a Notice of Revocation with respect to a Notice of Special Dividend Period, the next succeeding Dividend Period will be a 28-day Period (in the case of Series T28 Preferred Shares) or a 7-day Dividend Period the case of Series T7 Preferred Shares) provided that if the then-current Dividend Period in the case of the Series T28 Preferred Shares is a Special Dividend Period of less than 28 days, the next succeeding Dividend Period for such series will be the same length as the current Dividend Period. In addition, in the event Sufficient Clearing Bids are not made in the applicable Auction or such Auction is not held for any reason, such next succeeding Dividend Period will be a 28 day Dividend Period (in the case of Series T28 Preferred Shares) or a 7-day Dividend Period (in the case of Series T7 Preferred Shares) and the Corporation may not again give a Notice of Special Dividend Period of the Preferred Shares (and any such attempted notice shall be null and void) until Sufficient Clearing bids have been made in an Auction with respect to a 28-day Dividend Period (in the case of Series T28 Preferred Shares) or a 7-day Dividend Period (in the case of Series T7 Preferred Shares).

(d) (i) Holders shall not be entitled to any dividends, whether payable in cash, property or stock, in excess of full cumulative dividends, as herein provided, on the Preferred Shares. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment on the Preferred Shares that may be in arrears.

(ii) For so long as any share of the Preferred Shares is outstanding, the Corporation shall not declare, pay or set apart for payment any dividend or other distribution (other than a dividend or distribution paid in shares of, or options, warrants or rights to subscribe for or purchase, Common Stock or other stock, if any, ranking junior to the Preferred Shares as to dividends or upon liquidation) in respect of the Common Stock or any other stock of the Corporation ranking junior to or on a parity with the Preferred Shares as to dividends or upon liquidation, or call for redemption, redeem, purchase or otherwise acquire for consideration any shares of the Common Stock or any other such junior stock (except by conversion into or exchange for stock of the Corporation ranking junior to the Preferred Shares as to dividends and upon liquidation) or any other such Parity Stock (except by conversion into or exchange for stock of the Corporation ranking junior to or on a parity with the Preferred Shares as to dividends and upon liquidation), unless (A) immediately after such transaction, the Corporation shall have Moody's Eligible Assets and S&P Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount and the Corporation shall maintain the 1940 Act Preferred Shares Asset Coverage, (B) full cumulative dividends on Preferred Shares and shares of Other Preferred Shares due on or prior to the date of the transaction have been declared and paid or shall have been declared and sufficient funds for the payment thereof deposited with the Auction Agent, (C) any Additional Dividend required to be paid under paragraph 2(e) below on or before the date of such declaration or payment has been paid and (D) the Corporation has redeemed the full number of Preferred Shares required to be redeemed by any provision for mandatory redemption contained herein.

(e) Each dividend shall consist of (i) cash at the Applicable Rate and (ii) an uncertificated right (a "Right") to receive an Additional Dividend (as defined below). Each Right shall thereafter be independent of the share or Preferred Shares on which the dividend was paid. The Corporation shall cause to be maintained a record of each Right received by the respective Holders. The Corporation shall not be required to recognize any transfer of a Right.

If, in the case of a Dividend Period of 28 days or fewer, the Corporation retroactively allocates any net capital gains or other taxable income to Preferred Shares without having given advance notice thereof to the Auction Agent as described in paragraph 2(f) hereof (the amount of such allocation referred to herein as a "Retroactive Taxable Allocation") solely by reason of the fact that such allocation is made as a result of the redemption of all or a portion of the outstanding Preferred Shares or the liquidation of the Corporation, the Corporation will, within 90 days (and generally within 60 days) after the end of the Corporation's fiscal year for which a Retroactive Taxable Allocation is made, provide notice thereof to the Auction Agent and to each holder of a Right applicable to such Preferred Shares (initially Cede & Co. as nominee of The Depository Trust Company) during such fiscal year at such holder's address as the same appears or last appeared on the Stock Books of the Corporation. The Corporation will, within 30 days after such notice is given to the Auction Agent, pay to the Auction Agent (who will then distribute to such holders of Rights), out of funds legally available therefor, an amount equal to the aggregate Additional Dividend with respect to all Retroactive Taxable Allocations made to such holders during the fiscal year in question.

If the Corporation, in the case of a Dividend Period of 35 days or more, makes a Retroactive Taxable Allocation to a dividend paid on Preferred Shares, the Corporation will, within 90 days (and generally within 60 days) after the end of the Corporation's fiscal year for which a Retroactive Taxable Allocation is made, provide notice thereof to the Auction Agent and to each holder of a Right applicable to such Preferred Shares (initially Cede & Co. as nominee of The Depository Trust Company) during such fiscal year at such holder's address as the same appears or last appeared on the Stock Books of the Corporation. The Corporation will, within 30 days after such notice is given to the Auction Agent, pay to the Auction Agent (who will then distribute to such holders of Rights), out of funds legally available therefor, an amount equal to the aggregate Additional Dividend with respect to all Retroactive Taxable Allocations made to such holders during the fiscal year in question.

An "Additional Dividend" means payment to a holder of Preferred Shares of an amount which, when taken together with the aggregate amount of Retroactive Taxable Allocations allocated to such holder with respect to the fiscal year in question, would cause such holder's dividends from the aggregate of both the Retroactive Taxable Allocations and the Additional Dividend to be equal to the dollar amount of the dividends which would have been received and retained by such holder if the Retroactive Taxable Allocations had not been made. Such Additional Dividend shall be calculated
(i) without consideration being given to the time value of money; (ii) assuming that no holder of Preferred Shares is subject to the Federal alternative minimum tax with respect to dividends received from the Corporation; and (iii) assuming that each Retroactive Taxable Allocation would be taxable in the hands of each holder of Preferred Shares at the maximum marginal combined regular Federal income tax rate applicable to individuals or corporations, whichever is greater, in effect during the fiscal year in question.

(f) Whenever the Corporation intends to include any net capital gains or other taxable income in any dividend on Preferred Shares the Applicable Rate for which will be established at the next succeeding Auction, the Corporation will, in the case of a Dividend Period of 28 days or fewer, and may, in the case of a Dividend Period of 35 days or more, notify the Auction Agent of the amount to be so included at least five Business Days prior to the Auction Date on which the Applicable Rate for such dividend is to be established. If, in the case of a Dividend Period of 28 days or fewer, the Corporation retroactively allocates any net capital gains or other taxable income to a dividend paid on Preferred Shares without having given advance notice thereof to the Auction Agent as described in paragraph 2(f) hereof solely by reason of the fact that such allocation is made as a result of the redemption of all or a portion of the outstanding Preferred Shares or the liquidation of the Corporation, the Corporation will make certain payments to holders of Preferred Shares to offset the tax effect thereof. If, in the case of a Dividend Period of 35 days or more, the Corporation allocates any net capital gains or other taxable income to a dividend paid on Preferred Shares without having given advance notice thereof to the Auction Agent as described in Paragraph 2(f) hereof, the Corporation will make certain payments to holders of Preferred Shares to offset the tax effect thereof.

(g) No fractional share of Preferred Shares shall be issued.

3. Liquidation Rights. Upon any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, the Holders shall be entitled to receive, out of the assets of the Corporation available for distribution to shareholders, before any distribution or payment is made upon any Common Stock or any other capital stock ranking junior in right of payment upon liquidation to the Preferred Shares, the sum of $50,000 per share plus accumulated but unpaid dividends (whether or not earned or declared) thereon plus the premium, if any, resulting from the designation of a Premium Call Period to the date of distribution, and after such payment the holders of Preferred Shares will be entitled to no other payments other than Additional Dividends as provided in paragraph 2(e) hereof. If upon any liquidation, dissolution or winding up of the Corporation, the amounts payable with respect to the Preferred Shares and any other outstanding class or series of Preferred Stock of the Corporation ranking on a parity with the Preferred Shares as to payment upon liquidation are not paid in full, the Holders and the holders of such other class or series will share ratably in any such distribution of assets in proportion to the respective preferential amounts to which they are entitled. After payment of the full amount of the liquidating distribution to which they are entitled, the Holders will not be entitled to any further participation in any distribution of assets by the Corporation except for any Additional Dividends. A consolidation or merger of the Corporation with or into any other corporation or corporations or a sale, whether for cash, shares of stock, securities or properties, of all or substantially all or any part of the assets of the Corporation shall not be deemed or construed to be a liquidation, dissolution or winding up of the Corporation.

4. Redemption. (a) Preferred Shares shall be redeemable by the Corporation as provided below:

(i) To the extent permitted under the 1940 Act and Maryland law, upon giving a Notice of Redemption, the Corporation at its option may redeem Preferred Shares, in whole or in part, out of funds legally available therefor, at the Optional Redemption Price per share, on any Dividend Payment Date; provided, however, that no Preferred Shares shall be subject to optional redemption during a Non-Call Period. In addition, holders of Preferred Shares which are redeemed shall be entitled to receive Additional Dividends to the extent provided herein. The Corporation may not give a Notice of Redemption relating to an optional redemption as described in this paragraph 4(a)(i) or effect an optional redemption unless, at the time of giving such Notice of Redemption or effecting such optional redemption, the Corporation has available Deposit Securities with maturity or tender dates not later than the day preceding the applicable redemption date and having a value not less than the amount due to Holders by reason of the redemption of their Preferred Shares on such redemption date and, if as a result of such optional redemption, the Corporation would fail to maintain S&P Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value equal to the Preferred Shares Basic Maintenance Amount.

(ii) The Corporation shall redeem, out of funds legally available therefor, at the Mandatory Redemption Price per share, Preferred Shares to the extent permitted under the 1940 Act and Maryland law, on a date fixed by the Board of Directors, if the Corporation fails to maintain Moody's Eligible Assets and S&P Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount as provided in paragraph 7(a) or to satisfy the 1940 Act Preferred Shares Asset Coverage as provided in paragraph 6 and such failure is not cured on or before the Preferred Shares Basic Maintenance Cure Date or the 1940 Act Cure Date (herein respectively referred to as the "Cure Date"), as the case may be. In addition, holders of Preferred Shares so redeemed shall be entitled to receive Additional Dividends to the extent provided herein. The number of Preferred Shares to be redeemed shall be equal to the lesser of
(i) the minimum number of Preferred Shares the redemption of which, if deemed to have occurred immediately prior to the opening of business on the Cure Date, would together with all shares of Other Preferred Stock subject to redemption or retirement, result in the Corporation having S&P Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount or satisfaction of the 1940 Act Preferred Shares Asset Coverage, as the case may be, on such Cure Date (provided that, if there is no such minimum number of Preferred Shares and shares of Other Preferred Stock the redemption of which would have such result, all Preferred Shares and shares of Other Preferred Stock then outstanding shall be redeemed), and (ii) the maximum number of Preferred Shares, together with all shares of other Preferred Stock subject to redemption or retirement, that can be redeemed out of funds expected to be legally available therefor on such redemption date. In determining the number of Preferred Shares required to be redeemed in accordance with the foregoing, the Corporation shall allocate the number required to be redeemed which would result in the Corporation having Moody's Eligible Assets and S&P Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount or satisfaction of the 1940 Act Preferred Shares Asset Coverage, as the case may be, pro rata among Preferred Shares, Other Preferred Shares and other Preferred Stock subject to redemption pursuant to provisions similar to those contained in this paragraph 4(a)(ii) provided that, Preferred Shares which may not be redeemed at the option of the Corporation (a) will be subject to mandatory redemption only to the extent that other shares are not available to satisfy the number of shares required to be redeemed and (b) will be selected for redemption in an ascending order of outstanding number of days in the Non-Call Period during which such shares are not subject to optional redemption (with shares with the lowest number of days to be redeemed first) and by lot in the event of shares having an equal number of days in such period. The Corporation shall effect such redemption on a Business Day which is not later than 30 days after such Cure Date, except that if the Corporation does not have funds legally available for the redemption of all of the required number of Preferred Shares and shares of other Preferred Stock which are subject to mandatory redemption or the Corporation otherwise is unable to effect such redemption on or prior to 30 days after such Cure Date, the Corporation shall redeem those Preferred Shares which it is unable to redeem on the earliest practicable date on which it is able to effect such redemption out of funds legally available therefor.

(b) Notwithstanding any other provision of this paragraph 4, no Preferred Shares may be redeemed pursuant to paragraph 4(a)(i) of these Articles Supplementary unless all dividends in arrears on all remaining outstanding shares of Parity Stock shall have been or are being contemporaneously paid or declared and set apart for payment. In the event that less than all the outstanding Preferred Shares are to be redeemed and there is more than one Holder, the shares to be redeemed shall be selected by lot or such other method as the Corporation shall deem fair and equitable.

(c) Whenever Preferred Shares are to be redeemed, the Corporation, not less than 20 or more than 60 days prior to the date fixed for redemption, shall mail a notice ("Notice of Redemption") by first-class mail, postage prepaid, to each Holder of Preferred Shares to be redeemed and to the Auction Agent. The Corporation shall cause the Notice of Redemption also to be published in the eastern and national editions of The Wall Street Journal. The Notice of Redemption to set forth (i) the redemption date, (ii) the amount of the redemption price, (iii) the aggregate number of Preferred Shares to be redeemed, (iv) the place or places where Preferred Shares are to be surrendered for payment of the redemption price, (v) a statement that dividends on the shares to be redeemed shall cease to accumulate on such redemption date (except that holders may be entitled to Additional Dividends) and (vi) the provision of these Articles Supplementary pursuant to which such shares are being redeemed. No defect in the Notice of Redemption or in the mailing or publication thereof shall affect the validity of the redemption proceedings, except as required by applicable law.

If the Notice of Redemption shall have been given as aforesaid and, concurrently or thereafter, the Corporation shall have deposited in trust with the Auction Agent a cash amount equal to the redemption payment for the Preferred Shares to which such Notice of Redemption has been given with irrevocable instructions and authority to pay the redemption price to the Holders of such shares, then upon the date of such deposit or, if no such deposit is made, then upon such date fixed for redemption (unless the Corporation shall default in making the redemption payment), all rights of the Holders of such shares as shareholders of the Corporation by reason of the ownership of such shares will cease and terminate (except their right to receive the redemption price in respect thereof and any additional dividends, but without interest), and such shares shall no longer be deemed outstanding. The Corporation shall be entitled to receive, from time to time, from the Auction Agent the interest, if any, on such moneys deposited with it and the Holders of any shares so redeemed shall have no claim to any of such interest. In case the Holder of any shares so called for redemption shall not claim the redemption payment for his shares within one year after the date of redemption, the Auction Agent shall, upon demand, pay over to the Corporation such amount remaining on deposit and the Auction Agent shall thereupon be relieved of all responsibility to the Holder of such shares called for redemption and such Holder thereafter shall look only to the Corporation for the redemption payment.

5. Voting Rights. (a) General. Except as otherwise provided in the Charter, each Holder of Preferred Shares shall be entitled to one vote for each share held on each matter submitted to a vote of stockholders of the Corporation to which the stockholders are entitled to vote, and the holders of outstanding shares of Preferred Stock, including Preferred Shares, and of shares of Common Stock shall vote together as a single class with respect to all matters on which all stockholders are entitled to vote. Notwithstanding the preceding sentence, at the first annual meeting of stockholders, the holders of outstanding shares of Preferred Stock, including Preferred Shares, represented in person or by proxy shall be entitled as a class, and to the exclusion of the holders of all other securities and classes of capital stock of the Corporation, to elect one Class I director and one Class II director and shall thereafter be so entitled to elect any successors from time to time to the Class I and Class II directors so elected at any meeting of shareholders in which successors are elected. At each meeting of shareholders at which entire classes of Class I and Class II directors are to be elected, or at any meeting at which a successor to a director elected by the holders of Preferred Stock in accordance with this Section is to be elected (including directors elected pursuant to this sentence), the holders of outstanding shares of Preferred Stock, including Preferred Shares, represented in person or by proxy shall be entitled as a class and to the exclusion of the holders of all other securities and classes of capital stock of the Corporation to elect one Class I and one Class II director or to elect such successor. In the event that the Charter is amended to eliminate the classification of the Corporation's Board of Directors, the holders of outstanding shares of Preferred Stock, including Preferred Shares, represented in person or by proxy shall be entitled as a class, and to the exclusion of the holders of all other securities and classes of capital stock of the Corporation, to elect two directors. Subject to paragraph 5(b) hereof, the holders of outstanding shares of capital stock of the Corporation, voting as a single class, shall elect the balance of the directors.

(b) Right to Elect Majority of Board of Directors. During any period in which any one or more of the conditions described below shall exist (such period being referred to herein as a "Voting Period"), the number of directors constituting the Board of Directors shall be automatically increased by the smallest number that, when added to the two directors elected exclusively by the holders of shares of Preferred Stock, would constitute a majority of the Board of Directors as so increased by such smallest number; and the holders of shares of Preferred Stock shall be entitled, voting as a class on a one-vote-per-share basis (to the exclusion of the holders of all other securities and classes of capital stock of the Corporation), to elect such smallest number of additional directors, together with the two directors that such holders are in any event entitled to elect. A Voting Period shall commence:

(i) if at any time accumulated dividends (whether or not earned or declared, and whether or not funds are then legally available in an amount sufficient therefor) on the outstanding Preferred Shares equal to at least two full years' dividends shall be due and unpaid and sufficient cash or specified securities shall not have been deposited with the Auction Agent for the payment of such accumulated dividends; or

(ii) if at any time holders of any Preferred Stock are entitled to elect a majority of the directors of the Corporation under the 1940 Act.

Upon the termination of a Voting Period, the voting rights described in this paragraph 5(b) shall cease, subject always, however, to the revesting of such voting rights in the Holders upon the further occurrence of any of the events described in this paragraph 5(b).

(c) Right to Vote with Respect to Certain Other Matters. So long as any Preferred Shares are outstanding, the Corporation shall not, without the affirmative vote of the holders of a majority of the Outstanding shares of Preferred Stock outstanding at the time, in person or by proxy, at a meeting (voting separately as one class) or by the unanimous written consent of the holders of all Outstanding shares of Preferred Stock: (i) authorize, create or issue, or increase the authorized or issued amount of, any class or series of stock ranking prior to or on a parity with any series of Preferred Stock with respect to payment of dividends or the distribution of assets on liquidation, or increase the authorized amount of Preferred Shares or any other Preferred Stock (except that, notwithstanding the foregoing, but subject to the provisions of Section 13 of the 1940 Act, the Board of Directors, without the vote or consent of the Holders of Preferred Shares, may from time to time authorize, create and issue, and may increase the authorized or issued amount of, classes or series of Preferred Stock, including Preferred Shares, ranking on a parity with the Preferred Shares with respect to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Corporation, subject to continuing compliance by the Corporation with 1940 Act Preferred Shares Asset Coverage and Preferred Shares Basic Maintenance Amount requirements, provided that the Fund obtains written confirmation from Moody's (if Moody's is then rating Preferred Shares), S&P (if S&P is then rating Preferred Shares) or any Substitute Rating Agency (if any such Substitute Rating Agency is then rating Preferred Shares) that the issuance of such class or series would not impair the rating then assigned by such rating agency to the Preferred Shares), (ii) amend, alter or repeal the provisions of the Charter whether by merger, consolidation or otherwise, so as to adversely affect any of the contract rights expressly set forth in the Charter of holders of Preferred Shares or any Other Preferred Stock, (iii) authorize the Corporation's conversion from a closed-end to an open-end investment company as defined in Section 5(a) of the 1940 Act, or (iv) amend the provisions of the Charter which provide for the classification of the Board of Directors of the Corporation into three classes, each with a term of office of three years with only one class of directors standing for election in any year (presently Article VI of the Charter). To the extent permitted under the 1940 Act, the Corporation shall not approve any of the actions set forth in clause (i) or (ii) which adversely affects the contract rights expressly set forth in the Charter of a Holder of shares of a series of Preferred Shares differently than those of a Holder of shares of any other series of Preferred Shares without the affirmative vote of the holders of at least a majority of the Preferred Shares of each series adversely affected and Outstanding at such time, in person or by proxy, at a meeting (each such adversely affected series voting separately as a class) or by the unanimous written consent of the holders of all Outstanding shares of Preferred Stock. The Corporation shall notify Moody's and S&P 10 Business Days prior to any such vote described in clauses (i) and (ii). Unless a higher percentage is provided for under the Charter, the affirmative vote of the holders of a majority of the Outstanding shares of Preferred Stock, including Preferred Shares, voting together as a single class, will be required to approve any plan of reorganization (including bankruptcy proceedings) adversely affecting such shares or any action requiring a vote of security holders under Section 13(a) of the 1940 Act. The class vote of holders of shares of Preferred Stock, including Preferred Shares, described above will in each case be in addition to a separate vote of the requisite percentage of shares of Common Stock and shares of Preferred Stock, including Preferred Shares, voting together as a single class necessary to authorize the action in question. Notwithstanding the preceding sentence, to the extent permitted by Maryland General Corporation Law, no vote of holders of Common Stock, either separately or together with holders of Preferred Shares as a single class, shall be necessary to take the actions contemplated by clauses (i) and (ii) of the first sentence of this Section 5(c) and the holders of Common Stock shall not be entitled to vote in respect of such matters, unless, in the case of the actions contemplated by clause (ii) of the first sentence of this section 5(c), the action would adversely affect the contract rights expressly set forth in the Charter of the holders of Common Stock.

(d) Voting Procedures.

(i) As soon as practicable after the accrual of any right of the Holders of shares of Preferred Stock to elect additional directors as described in paragraph 5(b) above, the Corporation shall notify the Secretary of the Corporation and instruct the Secretary to call a special meeting of such Holders, by mailing a notice of such special meeting to such Holders, such meeting to be held not less than 10 nor more than 20 days after the date of mailing of such notice. If the Secretary of the Corporation does not call such a special meeting, it may be called by Holders of at least 25% of the votes entitled to be cast at such meeting on like notice. The record date for determining the Holders entitled to notice of and to vote at such special meeting shall be the close of business on the fifth Business Day preceding the day on which such notice is mailed. At any such special meeting and at each meeting held during a Voting Period, such Holders, voting together as a class (to the exclusion of the holders of all other securities and classes of capital stock of the Corporation), shall be entitled to elect the number of directors prescribed in paragraph 5(b) above on a one-vote-per-share basis. At any such meeting or adjournment thereof in the absence of a quorum, a majority of such holders present in person or by proxy shall have the power to adjourn the meeting without notice, other than by an announcement at the meeting, to a date not more than 120 days after the original record date.

(ii) For purposes of determining any rights of the Holders to vote on any matter or the number of shares required to constitute a quorum, whether such right is created by these Articles Supplementary, by the other provisions of the Charter, by statute or otherwise, a share of Preferred Shares which is not outstanding shall not be counted.

(iii) The terms of office of all persons who are directors of the Corporation at the time of a special meeting of Holders and holders of other Preferred Stock to elect directors shall continue, notwithstanding the election at such meeting by the Holders and such other holders of the number of directors that they are entitled to elect, and the persons so elected by the Holders and such other holders, together with the two incumbent directors elected by the Holders and such other holders of Preferred Stock and the remaining incumbent directors elected by the holders of the Common Stock and Preferred Stock, shall constitute the duly elected directors of the Corporation.

(iv) The terms of office of the additional directors elected by the Holders and holders of other Preferred Stock pursuant to paragraph 5(b) above shall terminate on the earliest date permitted by the Maryland General Corporation Law following the termination of a Voting Period, the remaining directors shall constitute the directors of the Corporation and the voting rights of the Holders and such other holders to elect additional directors pursuant to paragraph 5(b) above shall cease, subject to the provisions of the last sentence of paragraph 5(b)(ii).

(e) Exclusive Remedy. Unless otherwise required by law, the Holders of Preferred Shares shall not have any relative rights or preferences or other special rights other than those specifically set forth herein. The Holders of Preferred Shares shall have no preemptive rights or rights to cumulative voting. In the event that the Corporation fails to pay any dividends on the Preferred Shares, the exclusive remedy of the Holders shall be the right to vote for directors pursuant to the provisions of this paragraph 5.

(f) Notification to Moody's and S&P. In the event a vote of Holders of Preferred Shares is required pursuant to the provisions of
Section 13(a) of the 1940 Act, the Corporation shall, not later than ten business days prior to the date on which such vote is to be taken, notify Moody's and S&P that such vote is to be taken and the nature of the action with respect to which such vote is to be taken. Upon completion of any such vote, the Corporation shall notify Moody's and S&P as to the result of such vote.

6. 1940 Act Preferred Shares Asset Coverage. The Corporation shall maintain, as of the last Business Day of each month in which any share of Preferred Shares is outstanding, the 1940 Act Preferred Shares Asset Coverage.

7. Preferred Shares Basic Maintenance Amount. (a) The Corporation shall maintain, on each Valuation Date, and shall verify to its satisfaction that it is maintaining on such Valuation Date, (i) Moody's Eligible Assets having an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount and (ii) S&P Eligible Assets having an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount. Upon any failure to maintain the required Discounted Value, the Corporation will use its best efforts to alter the composition of its portfolio to reattain the Preferred Shares Basic Maintenance Amount on or prior to the Preferred Shares Basic Maintenance Cure Date.

(b) On or before 5:00 p.m., New York City time, on the third Business Day after a Valuation Date on which the Corporation fails to satisfy the Preferred Shares Basic Maintenance Amount, the Corporation shall complete and deliver to the Auction Agent, Moody's and S&P a complete Preferred Shares Basic Maintenance Report as of the date of such failure, which shall be deemed to have been delivered to the Auction Agent if the Auction Agent receives a copy or telecopy, telex or other electronic transcription thereof and on the same day the Corporation mails to the Auction Agent for delivery on the next Business Day the complete Preferred Shares Basic Maintenance Report. The Corporation shall also give a notice of cure of its failure to satisfy the Preferred Shares Basic Maintenance Amount along with the complete Preferred Shares Basic Maintenance Report to the Auction Agent, Moody's and S&P within three Business Days of its determination that it has satisfied such requirement following any period during which it has failed to satisfy such requirement. The Corporation will also deliver a Preferred Shares Basic Maintenance Report to the Auction Agent as of (i) the fifteenth day of each month (or, if such day is not a Business Day, the next succeeding Business Day) and (ii) the last Business Day of each month, in each case on or before the third Business Day after such day. The Corporation will also deliver a Preferred Shares Basic Maintenance Report to Moody's or S&P, as the case may be, for each Valuation Date that the Discounted Value of Moody's Eligible Assets or S&P Eligible Assets is less than or equal to 125% of the Preferred Shares Basic Maintenance Amount, provided, however, that if the Valuation Date is every day that is a Business Day, the Corporation will deliver a Preferred Shares Basic Maintenance Report to Moody's or S&P, as the case may be, for each Valuation Date that the Discounted Value of Moody's Eligible Assets or S&P Eligible Assets is less than or equal to 105% of the Preferred Shares Basic Maintenance Amount. The Corporation will deliver a Preferred Shares Basic Maintenance Report to Moody's upon request and when the Corporation redeems any shares of Common Stock. The Corporation will deliver a Preferred Shares Basic Maintenance Report to S&P upon request. A failure by the Corporation to deliver a Preferred Shares Basic Maintenance Report under this paragraph 7(b) shall be deemed to be delivery of a Preferred Shares Basic Maintenance Report indicating the Discounted Value for S&P Eligible Assets and Moody's Eligible Assets of the Corporation is less than the Preferred Shares Basic Maintenance Amount, as of the relevant Valuation Date.

(c) Within ten Business Days after the date of delivery of the Preferred Shares Basic Maintenance Report and a Certificate of Minimum Liquidity in accordance with paragraph 7(b) above relating to a Quarterly Valuation Date, the Corporation shall cause the Independent Accountant to confirm in writing to the Auction Agent. Moody's and S&P (i) the mathematical accuracy of the calculations reflected in such Report (and in any other Preferred Shares Basic Maintenance Report, randomly selected by the Independent Accountant, that was delivered by the Corporation during the quarter ending on such Quarterly Valuation Date) and (with respect to S&P only while S&P is rating the Preferred Shares) such Certificate, (ii) that, in such Report (and in such randomly selected Report), the Corporation correctly determined the assets of the Corporation which constitute S&P Eligible Assets or Moody's Eligible Assets, as the case may be, at such Quarterly Valuation Date in accordance with these Articles Supplementary, (iii) that, in such Report (and in such randomly selected Report), the Corporation determined whether the Corporation had, at such Quarterly Valuation Date (and at the Valuation Date addressed in such randomly-selected Report) in accordance with these Articles Supplementary, S&P Eligible Assets of an aggregate Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount and Moody's Eligible Assets of an aggregate Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount, (iv) that (with respect o S&P only) in such Certificate, the Corporation determined the Minimum Liquidity Level and the Corporation's Deposit Securities in accordance with these Articles Supplementary, including maturity or tender date, (v) with respect to the S&P rating on Municipal Obligations, the issuer name, issue size and coupon rate listed in such Report and (with respect to S&P only) such Certificate, that the Independent Accountant has requested that S&P verify such information and the Independent Accountant shall provide - listing in its letter of any differences, (vi) with respect to the Moody's ratings on Municipal Obligations the issuer name, issue size and coupon rate listed in such Report and (with respect to S&P only) such Certificate, that such information has been verified by Moody's (in the event such information is not verified by Moody's the Independent Accountant will inquire of Moody's what such information is, and provide a listing in its letter of any differences) and (vii) with respect to the bid or mean price (or such alternative permissible factor used in calculating the Market Value) provided by the custodian of the Corporation's assets to the Corporation for purposes of valuing securities in the Corporation's portfolio, the Independent Accountant has traced the price used in such Report and (with respect to S&P only) such Certificate to the bid or mean price listed in such Report and (with respect to S&P only) such Certificate as provided to the Corporation and verified that such information agrees (in the event such information does not agree, the Independent Accountant will provide a listing in its letter of such differences) (such confirmation is herein called the "Accountant's Confirmation").

(d) Within ten Business Days after the date of delivery to the Auction Agent, S&P and Moody's of a Preferred Shares Basic Maintenance Report in accordance with paragraph 7(b) above relating to any Valuation Date on which the Corporation failed to maintain S&P Eligible Assets with an aggregate Discounted Value and Moody's Eligible Assets with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount, and relating to the Preferred Shares Basic Maintenance Cure Date with respect to such failure, the Independent Accountant will provide to the Auction Agent, S&P and Moody's an Accountant's Confirmation as to such Preferred Shares Basic Maintenance Report.

(e) If any Accountant's Confirmation delivered pursuant to Subparagraph (c) or (d) of this paragraph 7 shows that an error was made in the Preferred Shares Basic Maintenance Report for a particular Valuation Date for which such Accountant's Confirmation was required to be delivered, or shows that a lower aggregate Discounted Value for the aggregate of all S&P Eligible Assets or Moody's Eligible Assets, as the case may be, of the Corporation was determined by the Independent Accountant, the calculation or determination made by such Independent Accountant shall be final and conclusive and shall be binding on the Corporation and the Corporation shall accordingly amend and deliver the Preferred Shares Basic Maintenance Report to the Auction Agent, S&P and Moody's promptly following receipt by the Corporation of such Accountant's Confirmation.

(f) On or before 5:00 p.m., New York City time, on the first Business Day after the Date of Original Issue of the Preferred Shares, the Corporation will complete and deliver to S&P and Moody's a Preferred Shares Basic Maintenance Report as of the close of business on such Date of Original Issue. Within five business days of such Date of Original Issue, the Corporation shall cause the Independent Accountant to confirm in writing to S&P and Moody's (i) the mathematical accuracy of the calculations reflected in such Report and (ii) that the aggregate Discounted Value of S&P Eligible Assets and the aggregate Discounted Value of Moody's Eligible Assets reflected thereon equals or exceeds the Preferred Shares Basic Maintenance Amount reflected thereon.

(g) For so long as Preferred Shares are rated by Moody's, in managing the Corporation's portfolio, the Corporation shall require that the Adviser will not alter the composition of the Corporation's portfolio if, in the reasonable belief of the Adviser, the effect of any such alteration would be to cause the Corporation to have Moody's Eligible Assets with an aggregate Discounted Value, as of the immediately preceding Valuation Date, less than Preferred Shares Basic Maintenance Amount as of such Valuation Date; provided, however, that in the event that, as of the immediately preceding Valuation Date, the aggregate Discounted Value of Moody's Eligible Assets exceeded the Preferred Shares Basic Maintenance Amount by twenty-five percent or less (or, in the event the Valuation Date is every day that is a Business Day, five percent or less), the Adviser will not alter the composition of the Corporation's portfolio in a manner reasonably expected to reduce the aggregate Discounted Value of Moody's Eligible Assets unless the Corporation shall have confirmed that, after giving effect to such alteration, the aggregate Discounted Value of Moody's Eligible Assets would exceed the Preferred Shares Basic Maintenance Amount.

8. Minimum Liquidity Level. (i) For so long as any Preferred Shares are rated by S&P, the Corporation shall be required to have, as of each Valuation Date, Dividend Coverage Assets having in aggregate a value not less than the Dividend Coverage Amount

(ii) As of each Valuation Date as long as any Preferred Shares are rated by S&P, the Corporation shall determine (A) the Market Value of the Dividend Coverage Assets owned by the Corporation as of that Valuation Date, (B) the Dividend Coverage Amount on that Valuation Date, and (C) whether the Minimum Liquidity Level is met as of that Valuation Date. The calculations of the Dividend Coverage Assets, the Dividend Coverage Amount and whether the Minimum Liquidity Level is met shall be set forth in a certificate (a "Certificate of Minimum Liquidity") dated as of the Valuation Date. The Preferred Shares Basic Maintenance Report and the Certificate of Minimum Liquidity may be combined in one certificate. The Corporation shall cause the Certificate of Minimum Liquidity to be delivered to S&P not later than the close of business on the third Business Day after the Valuation Date applicable to such Certificate pursuant to paragraph 7(b). The Minimum Liquidity Level shall be deemed to be met as of any date of determination if the Corporation has timely delivered a Certificate of Minimum Liquidity relating to such date which states that the same has been met and which is not manifestly inaccurate. In the event that a Certificate of Minimum Liquidity is not delivered to S&P when required, the Minimum Liquidity Level shall be deemed not to have been met as of the applicable date.

(iii) If the Minimum Liquidity Level is not met as of any Valuation Date, then the Corporation shall purchase or otherwise acquire Dividend Coverage Assets to the extent necessary so that the Minimum Liquidity Level is met as of the fifth Business Day, provide to S&P a Certificate of Minimum Liquidity setting forth the calculations of the Dividend Coverage Assets and the Dividend Coverage Amount and showing that the Minimum Liquidity Level is met as such fifth Business Day together with a report of the custodian of the Corporation's assets confirming the amount of the Corporation's Dividend Coverage Assets as of such fifth Business Day.

9. Certain Other Restrictions. (a) So long as there are Preferred Shares Outstanding, the Corporation will enter into futures and options transactions only for bona fide hedging purposes and not for leveraging or speculative purposes. So long as Moody's and S&P are rating the Preferred Shares, the Corporation will only engage in futures or options transactions in accordance with the then-current guidelines of such ratings agencies, only if it is valuing its assets daily and only after it has received written confirmation from Moody's and S&P, as appropriate, that such transactions would not impair the ratings then assigned by S&P and Moody's to Preferred Shares. The S&P guidelines in effect as of the Date of Original Issue are set forth in their entirety in the following paragraph. The Corporation may engage in futures and options transactions in accordance therewith and such transactions shall have the consequences included in such guidelines set forth therein (as such guidelines are amended, modified and supplemented from time to time by S&P), provided, however, that it may not engage in any such transactions unless it has satisfied the relevant provisions of this paragraph relating to complying with Moody's guidelines and obtaining written confirmation from Moody's and S&P.

For so long as Preferred Shares are rated by S&P, the Corporation will not, unless it has received written confirmation from S&P that any such action would not impair the rating then assigned by S&P to Preferred Shares, purchase or sell futures contracts or options thereon or write uncovered put or uncovered call options in portfolio securities except (provided that the Corporation has received such written confirmation in advance from S&P) that (i) the Corporation may engage in S&P Hedging Transactions based on the Municipal Index, provided that (A) the Corporation shall not engage in any S&P Hedging Transaction based on the Municipal Index (other than Closing Transactions) which would cause the Corporation at the time of such transaction to own or have sold (1) more than 1,000 outstanding futures contracts based on the Municipal Index, (2) outstanding futures contracts based on Municipal Index exceeding in number 25% of the quotient of the fair market value of the Corporation's total assets divided by 100,000 or (3) outstanding futures contracts based on the Municipal Index exceeding in number 10% of the average number of daily traded futures contracts based on the Municipal Index in the month prior to the time of effecting such transaction as reported by The Wall Street Journal and (ii) the Corporation may engage in S&P Hedging Transactions based on Treasury Bonds, provided that (A) the Corporation shall not engage in any S&P Hedging Transactions based on Treasury Bonds (other than Closing Transactions) which would cause the Corporation at the time of such transaction to own or have sold the lesser of (1) outstanding futures contracts based on Treasury Bonds exceeding in number 25% of the quotient of the fair market value of the Corporation's total assets divided by 100,000 or (2) outstanding futures contracts based on Treasury Bonds exceeding in number 10% of the average number of daily traded futures contracts based on Treasury Bonds in the month prior to the time of effecting such transaction as reported by The Wall Street Journal. For so long as Preferred Shares are rated by S&P, the Corporation will engage in Closing Transactions to close out any outstanding futures contract which the Corporation owns or has sold or any outstanding option thereon owned by the Corporation in the event
(i) the Corporation does not have S&P Eligible Assets with an aggregate Discounted Value equal to or greater than the Preferred Shares Maintenance Amount on two consecutive Valuation Dates and
(ii) the Corporation is required to pay Variation Margin on the second such Valuation Date. For so long as Preferred Shares are rated by S&P, the Corporation will engage in a Closing Transaction to close out any outstanding futures contract or option thereon in the month prior to the delivery month under the terms of such futures contract or option thereon unless the Corporation holds securities deliverable under such terms. For purposes of calculating the Discounted Value of S&P Eligible Assets to determine compliance with the Preferred Shares Basic Maintenance Amount, such Discounted Value shall be reduced to an amount equal to (i) 30% of the aggregate settlement value, as marked to market, of any outstanding futures contracts based on the Municipal Index which are owned by the Trust plus (ii) 25% of the aggregate settlement value, as marked to market, of any outstanding futures contracts based on Treasury Bonds which contracts are owned by the Corporation. For so long as Preferred Shares are rated by S&P, when the Corporation writes a futures contract or option thereon, it will maintain an amount of cash, cash equivalents or short-term, fixed-income securities in a segregated account with the Corporation's custodian, so that the amount so segregated plus the amount of Initial Margin and Variation Margin held in the account of the Corporation's broker equals the fair market value of the futures contract, except that in the event the Corporation writes a futures contract or option thereon which requires delivery of an underlying security, the Corporation shall hold such underlying security.

(b) For so long as Preferred Shares are rated by Moody's or S&P, the Corporation will not, unless it has received written confirmation from Moody's and/or S&P, as the case may be, that such action would not impair the ratings then assigned to Preferred Shares by Moody's and/or S&P, as the case may be, (i) borrow money, (ii) engage in short sales of securities, (iii) lend any securities, (iv) issue any class or series of stock ranking prior to or on a parity with the Preferred Shares with respect to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up of the Corporation, (v) reissue any Preferred Shares previously purchased or redeemed by the Corporation, (vi) merge or consolidate into or with any other corporation, (vii) change the Pricing Service or (viii) engage in reverse repurchase agreements.

10. Notice. All notices or communications, unless otherwise specified in these Articles Supplementary, shall be sufficiently given if in writing and delivered in person or mailed by first-class mail, postage prepaid. Notice shall be deemed given on the earlier of the date received or the date seven days after which such notice is mailed.

The Applicable Percentage will be determined based on (i) the lower of the credit rating or ratings assigned on such date to such shares by Moody's and S&P (or if Moody's or S&P or both shall not make such ratings available, the equivalent of either or both of such ratings by a Substitute Rating Agency or two Substitute Rating Agencies or, in the event that only one such rating shall be available, such rating) and

For the purposes hereof, the communication to a Broker-Dealer of information referred to in clause (A) or (B) of this paragraph 11(b)(i) is hereinafter referred to an "Order" and each Existing Holder and each Potential Holder placing an Order is hereinafter referred to as a "Bidder"; an Order containing the information referred to in clause (A)(1) of this paragraph 11(b)(i) is hereinafter referred to as a "Hold Order"; an Order containing the information referred to in clause (A)(2) or (B) of this paragraph 11(b)(i) is hereinafter referred to as a "Bid"; and an Order containing the information referred to in clause (A)(3) of this paragraph 11(b)(i) is hereinafter referred to as a "Sell Order".

(i) (A) A Bid by an Existing Holder shall constitute an irrevocable offer to sell:

(1) the number of Outstanding Preferred Shares specified in such Bid if the Applicable Rate determined on such Auction Date shall be less than the rate per annum or Spread specified in such Bid; or

(2) such number of a lesser number of Outstanding Preferred Shares to be determined as set forth in paragraph 11(e)(i)(D) if the Applicable Rate determined on such Auction Date shall be equal to the rate per annum or Spread specified therein; or

(3) a lesser number of Outstanding Preferred Shares to be determined as set forth in paragraph 11(e)(ii)(C) if such specified rate per annum shall be higher than the Maximum Applicable Rate and Sufficient Clearing Bids do not exist.

(B) A Sell Order by an Existing Holder shall constitute an irrevocable offer to sell:

(1) the number of Outstanding Preferred Shares specified in such Sell Order; or

(2) such number or a lesser number of Outstanding Preferred Shares to be determined as set forth in paragraph 11(e)(ii)(C) if Sufficient Clearing Bids do not exist.

(2) such number or a lesser number of Outstanding Preferred Shares to be determined as set forth in paragraph 11(e)(i)(E) if the Applicable Rate determined on such Auction Date shall be equal to the rate per annum or Spread specified therein.

(c) Submission of Orders by Broker-Dealers to Auction Agent.

(i) Each Broker-Dealer shall submit in writing or through the Auction Agent's Auction Processing System to the Auction Agent prior to the Submission Deadline on each Auction Date all Orders obtained by such Broker-Dealer and specifying with respect to each Order:

(A) the name of the Bidder placing such Order;

(B) the aggregate number of Outstanding Preferred

Shares that are subject of such Order;

(C) to the extent that such Bidder is an Existing Holder;

(1) the number of Outstanding shares, if any,

of Preferred Shares subject to any Hold Order placed by such Existing Holder;

(2) the number of Outstanding shares, if any, of Preferred Shares subject to any Bid placed by such Existing Holder and the rate per annum or Spread specified in such Bid; and

(3) the number of Outstanding shares, if any, of Preferred Shares subject to any Sell Order placed by such Existing Holder; and

(D) (i) to the extent such Bidder is a Potential Holder, the rate per annum or Spread specified in such Potential Holder's Bid.

(ii) If any rate per annum or Spread specified in any Bid contains more than three figures to the right of the decimal point, the Auction Agent shall round such rate up to the next highest one- thousandth (.001) of 1% and shall round such Spread to the next highest one-thousandth (.001) of a basis point.

(iii) If an Order or Orders covering all of the Outstanding Preferred Shares held by an Existing Holder is not submitted to the Auction Agent prior to the Submission Deadline, the Auction Agent shall deem a Hold Order to have been submitted on behalf of such Existing Holder covering the number of Outstanding Preferred Shares held by such Existing Holder and not subject to Orders submitted to the Auction Agent; provided, however, that with respect to an Auction to establish a Special Dividend Period longer than 91 days, the Auction Agent shall deem a Sell Order to have been submitted on behalf of such Existing Holder covering such number of Outstanding Preferred Shares.

(iv) If one or more Orders on behalf of an Existing Holder covering in the aggregate more than the number of Outstanding Preferred Shares held by such Existing Holder are submitted to the Auction Agent, such Orders shall be considered valid as follows and in the following order of priority:

(A) any Hold Order submitted on behalf of such Existing Holder shall be considered valid up to and including the number of Outstanding Preferred Shares held by such Existing Holder; provided that if more than one Hold Order is submitted on behalf of such Existing Holder and the number of Preferred Shares subject to such Hold Orders exceeds the number of Outstanding Preferred Shares held by such Existing Holder, the number of Preferred Shares subject to each of such Hold Orders shall be reduced pro rata so that such Hold Orders, in the aggregate, will cover exactly the number of Outstanding Preferred Shares held by such Existing Holder;

(B) any Bids submitted on behalf of such Existing Holder shall be considered valid, in the ascending order of their respective rates per annum or Spread, if more than one Bid is submitted on behalf of such Existing Holder, up to and including the excess of the number of Outstanding Preferred Shares held by such Existing Holder over the number of Preferred Shares subject to any Hold Order referred to in paragraph 11(c)(iv)(A) above (and if more than one Bid submitted on behalf of such Existing Holder specifies the same rate per annum or Spread and together they cover more than the remaining number of shares that can be the subject of valid Bids after application of paragraph 11(c)(iv)(A) above and of the foregoing portion of this paragraph 11(c)(iv)(B) to any Bid or Bids specifying a lower rate or rates per annum or Spread, the number of shares subject to each of such Bids shall be reduced pro rata so that such Bids, in the aggregate, cover exactly such remaining number of shares); and the number of shares, if any, subject to Bids not valid under this paragraph 11(c)(iv)(B) shall be treated as the subject of a Bid by a Potential Holder; and

(C) any Sell Order shall be considered valid up to and including the excess of the number of Outstanding Preferred Shares held by such Existing Holder over the number of Preferred Shares subject to Hold Orders referred to in paragraph 11(c)(iv)(A) and Bids referred to in paragraph 11(c)(iv)(B); provided that if more than one Sell Order is submitted on behalf of any Existing Holder and the number of Preferred Shares subject to such Sell Orders is greater than such excess, the number of Preferred Shares subject to each of such Sell Orders shall be reduced pro rata so that such Sell Orders, in the aggregate, cover exactly the number of Preferred Shares equal to such excess.

(v) If more than one Bid is submitted on behalf of any Potential Holder, each Bid submitted shall be a separate Bid with the rate per annum or Spread and number of Preferred Shares specified.

(vi) Any Bid by an Existing Holder that specifies a Spread, with respect to an Auction in which a Spread is not included in any Bid Requirements or in which there are no bid Requirements and any Order that does not specify a Spread with respect to an Auction in which a Spread is included in any bid Requirements shall be treated as a Sell Order.

(d) Determination of Sufficient Clearing Bids, Winning Bid Rate and Applicable Rate.

(i) Not earlier than the Submission Deadline on each Auction Date, the Auction Agent shall assemble all Orders submitted or deemed submitted to it by the Broker-Dealers (each such Order as submitted or deemed submitted by a Broker-Dealer being hereinafter referred to individually as a "Submitted Hold Order" a "Submitted Bid" a "Submitted Sell Order", as the case may be, or as a "Submitted Order") and shall determine:

(A) the excess of the total number of Outstanding Preferred Shares over the number of Outstanding Preferred Shares that are the subject of Submitted Hold Orders (such excess being hereinafter referred to as the "Available Preferred Shares");

(B) from the Submitted Orders whether the number of Outstanding Preferred Shares that are the subject of Submitted bids by Potential Holders specifying one or more rates per annum or Spreads that result in one or more rates per annum on such date equal to or lower than the Maximum Applicable Rate in effect for the first Dividend Payment Period after the auction Date exceeds or is equal to the sum of:

(1) the number of outstanding Preferred Shares that are the subject of Submitted Bids by Existing Holders specifying one or more rates per annum or Spreads that result in one or more rates per annum on such date higher than such Maximum Applicable Rate, and

(2) the number of Outstanding Preferred Shares that are subject to Submitted Sell Orders (if such excess or such equality exists (other than because the number of Outstanding Preferred Shares in clauses (1) and (2) above are each zero because all of the Outstanding Preferred Shares are the subject of Submitted Hold Orders), such Submitted Bids by Potential Holders being hereinafter referred to collectively as "Sufficient Clearing Bids"); and

(C) if Sufficient Clearing Bids exist, the lowest rate per annum or, in the case of an, Auction with Bid Requirements including a Spread, the lowest Spread specified in the Submitted Bids (the "Winning Bid Rate") that if:

(1) each Submitted Bid from

Existing Holders specifying the Winning Bid Rate and all other Submitted Bids from Existing Holders specifying lower rates per annum or Spreads were rejected, thus entitling such Existing Holders to continue to hold the Preferred Shares that are the subject of such Submitted Bids, and

(2) each Submitted Bid from Potential Holders specifying the Winning Bid Rate and all other Submitted Bids from Potential Holders specifying lower rates per annum or Spreads were accepted, thus entitling the Potential Holders to purchase the Preferred Shares that are the subject of such Submitted Bids, would result in the number of shares subject to all Submitted Bids specifying the Winning Bid Rate or a lower rate per annum or Spread being at least equal to the Available Preferred Shares.

(D) For purposes of these Article Supplementary, a positive Spread shall be considered lower than another positive Spread to the extent it is a lower number, a Spread of Zero shall be considered lower than a positive Spread, a negative Spread shall be considered lower than a Spread of zero and a negative Spread shall be considered lower than another negative Spread to the extent it is a higher number.

(ii) Promptly after the Auction Agent has made the determinations pursuant to paragraph 11(d)(i), the Auction Agent shall advise the Corporation of the Maximum Applicable Rate (or, in the event the Corporation has specified a Maximum Applicable Rate or Rates, or a Minimum Applicable Rate or Rates the Auction Agent shall confirm to the Corporation the calculation of such Maximum Applicable Rate or Rules or such Minimum Applicable Rate or Rates) and based on such determinations, the Applicable Rate for the next succeeding Dividend Period as follows:

(A) if Sufficient Clearing Bids exist, that the Applicable Rate for the next succeeding Dividend Period shall be equal to the Winning Bid Rate, subject to the effect of any applicable Minimum Applicable Rate and any applicable Maximum Applicable Rate;

(B) if Sufficient Clearing Bids do not exist (other than because all of the Outstanding Preferred Shares are the subject of Submitted Hold Orders and other than in the event the Auction is being conducted with respect to a Special Dividend Period), that the Applicable Rate for the next succeeding Dividend Period shall be equal to the Maximum Applicable Rate;

(C) if all of the Outstanding Preferred Shares are the subject of Submitted Hold Orders that the Dividend Period next succeeding the Auction shall automatically be the same length as the immediately preceding Dividend Period and the Applicable Rate for the next succeeding Dividend Period will be the higher of the 30-day "AA" Composite Commercial Paper Rate and the Taxable Equivalent of the Short- Term Municipal Bond Rate multiplied by 1 minus the maximum marginal regular Federal individual income tax rate then applicable to ordinary income or the maximum marginal regular Federal corporate tax rate then applicable, whichever is greater (or 90% of such rate if the Corporation has provided notification to the Auction Agent prior to the Auction establishing the Applicable Rate for any dividend pursuant to paragraph 2(f) hereof that net capital gains or other taxable income will be included in such dividend on Preferred Shares) on the date of the Auction; or

(D) If the Auction is being conducted with respect to a Special Dividend Period and Sufficient Clearing Bids do not exist, that the Dividend Period next succeeding the Auction shall automatically be 28 days (in the case of Series T28 Preferred Shares) or 7 days (in the case of Series T7 Preferred Shares) and the Applicable Rate for the next succeeding Dividend Period will be as set forth in paragraph 11(d)(ii)(C) above.

(e) Acceptance and Rejection of Submitted Bids and Submitted Sell Orders and Allocation of Shares. Based on the determinations made pursuant to paragraph 11(d)(i), the Submitted Bids and Submitted Sell Orders shall be accepted or rejected and the Auction Agent shall take such other action as set forth below:

(i) If Sufficient Clearing Bids have been made, subject to the provisions of paragraph 11(e) (iii) and paragraph
11(e) (iv), Submitted Bids and Submitted Sell Orders shall be accepted or rejected in the following order of priority and all other Submitted Bids shall be rejected:

(A) the Submitted Sell Orders of Existing Holders shall be accepted and the Submitted Bid of each of the Existing Holders specifying any rate per annum or Spread that is higher than the Winning Bid Rate shall be accepted, thus requiring each such Existing Holder to sell the Outstanding Preferred Shares that are the subject of such Submitted Sell Order or Submitted Bid;

(B) the Submitted Bid of each of the Existing Holders specifying any rate per annum or Spread that is lower than the Winning Bid Rate shall be rejected, thus entitling each such Existing Holder to continue to hold the Outstanding Preferred Shares that are the subject of such Submitted Bid;

(C) the Submitted Bid of each of the Potential Holders specifying any rate per annum that is lower than the Winning Bid Rate or Spread shall be accepted;

(D) the Submitted Bid of each of the Existing Holders specifying a rate per annum or Spread that is equal to the Winning Bid Rate shall be rejected, thus entitling each such Existing Holder to continue to hold the Outstanding Preferred Shares that are the subject of such Submitted Bid, unless the number of Outstanding Preferred Shares subject to all such Submitted Bids shall be greater than the number of Outstanding Preferred Shares ("Remaining Shares") equal to the excess of the Available Preferred Shares over the number of Outstanding Preferred Shares subject to Submitted Bids described in paragraph 11(e) (i) (B) and paragraph 11(e) (i)(C), in which event the Submitted Bids of each such Existing Holder shall be accepted, and each such Existing Holder shall be required to sell Outstanding Preferred Shares, but only in an amount equal to the difference between (1) the number of Outstanding Preferred Shares then held by such Existing Holder subject to such Submitted Bid and (2) the number of Preferred Shares obtained by multiplying
(x) the number of Remaining Shares by (y) a fraction the numerator of which shall be the number of Outstanding Preferred Shares held by such Existing Holder subject to such Submitted bid and the denominator of which shall be the sum of the numbers of outstanding Preferred Shares subject to such Submitted Bids made by all such Existing Holders that specified a rate per annum equal or Spread to the Winning Bid Rate; and

(E) the Submitted Bid of each of the Potential Holders specifying a rate per annum or Spread that is equal to the Winning Bid Rate shall be accepted but only in an amount equal to the number of Outstanding Preferred Shares obtained by multiplying (x) the difference between the Available Preferred Shares and the number of Outstanding Preferred Shares subject to Submitted Bids described n paragraph 11(e)(i)(B), paragraph 11(e)(i)(C) and paragraph 11(e)(i)(D) by (y) a fraction the numerator of which shall be the number of Outstanding Preferred Shares subject to such Submitted Bid and the denominator of which shall be the sum of the numbers of Outstanding Preferred Shares subject to such Submitted Bids made by all such Potential Holders that specified a rate per annum or Spread equal to the winning Bid Rate.

(ii) If Sufficient Clearing Bids have not been made (other than because all of the Outstanding Preferred Shares are subject to Submitted Hold Orders), subject to the provisions of paragraph 11(e) (iii), Submitted Orders shall be accepted or rejected as follows in the following order of priority and all other Submitted Bids shall be rejected:

(A) The Submitted Bid of each Existing Holder specifying any rate per annum or Spread that is equal to or lower than the Maximum Applicable Rate (a Bid specifying a Spread being converted to a rate per annum for this purpose by applying the spread to the most recently available Reference Index or Reference Security) shall be rejected, thus entitling such Existing Holder to continue to hold the Outstanding Preferred Shares that are the subject of such Submitted Bid;

(B) the Submitted Bid of each Potential Holder specifying any rate per annum or Spread that is equal to or lower than the Maximum Applicable Rate (a Bid specifying a Spread being converted to a rate per annum for this purpose by applying the Spread to the most recently available Reference Index or Reference Security) shall be accepted, thus requiring such Potential Holder to purchase the Outstanding Preferred Shares that are the subject of such Submitted Bid; and

(C) the Submitted Bids of each Existing Holder specifying any rate per annum or spread that is higher than the Maximum Applicable Rate (a Bid specifying a Spread being converted to a rate per annum for this purpose by applying the Spread to the most recently available Reference Index or Reference Security) shall be accepted, and the Submitted Sell Orders of each Existing Holder shall be accepted in both cases only in an amount equal to the difference between (1) the number of Outstanding Preferred Shares then held by such Existing Holder subject to such Submitted Bid or Submitted Sell Order and (2) the number of Preferred Shares obtained by multiplying (x) the difference between the Available Preferred Shares and the aggregate number of outstanding Preferred Shares subject to Submitted Bids described in paragraph 11(e)(ii)(A) and paragraph 11(e)(ii)(B) by (y) a fraction the numerator of which shall be the number of Outstanding Preferred Shares subject to such Submitted Bid or Submitted Sell Order and the denominator of which shall be the number of Outstanding Preferred Shares subject to all such Submitted Bids and Submitted Sell Orders.

(iii) If, as a result of the procedures described in paragraph 11(e)(i) or paragraph 11(e)(ii), any Existing Holder would be entitled or required to sell, or any Potential Holder would be entitled or required to purchase, a fraction of a share of Preferred Shares on any Auction Date, the Auction Agent shall, in such manner as in its sole discretion it shall determine, round up or down the number of Preferred Shares to be purchased or sold by any Existing Holder or Potential Holder on such Auction Date so that each Outstanding share of Preferred Shares purchased or sold by each Existing Holder or Potential Holder on such Auction Date shall be a whole share of Preferred shares.

(iv) If, as a result of the procedures described in paragraph 11(e)(i), any Potential Holder would be entitled or required to purchase less than a whole share of Preferred Shares on any Auction Date, the Auction Agent shall, in such manner as in its sole discretion it shall determine, allocate Preferred Shares for purchase among Potential Holders so that only whole Preferred Shares are purchased on such Auction Date by any Potential Holder, even if such allocation results in one or more of such Potential Holders not purchasing any Preferred Shares on such Auction Date.

(v) Based on the results of each Auction, the Auction Agent shall determine, with respect to each Broker-Dealer that submitted Bids or Sell Orders on behalf of Existing Holders or Potential Holders, the aggregate number of Outstanding Preferred Shares to be purchased and the aggregate number of Outstanding Preferred Shares to be sold by such Potential Holders and Existing Holders and to, the extent that such aggregate number of Outstanding shares to be purchased and such aggregate number of Outstanding shares to be sold differ, the Auction Agent shall determine to which other Broker-Dealer or Broker-Dealers acting for one or more purchasers such Broker-Dealer shall deliver, or from which other Broker-Dealer or Broker- Dealers acting for one or more sellers such Broker-Dealer shall receive, as the case may be, Outstanding Preferred Shares.

(f) Miscellaneous. An Existing Holder (A) may sell, transfer or otherwise dispose of Preferred Shares only pursuant to a Bid or Sell Order in accordance with the procedures described in this paragraph 11 or to or through a broker-dealer, provided that in the case of all transfers other than pursuant to Auctions such Existing Holder, its Broker-Dealer or its Agent Member advises the Auction Agent of such transfer and (B) except as otherwise required by law, shall have the ownership of the Preferred Shares held by it maintained in book entry form by the Securities Depository in the account of its Agent Member, which in turn will maintain records of such Existing Holder's beneficial ownership. Neither the Corporation nor any Affiliate shall submit an Order in any Auction. Any Existing Holder that is an Affiliate shall not sell, transfer or otherwise dispose of Preferred Shares to any Person other than the Corporation. All of the outstanding Preferred Shares of each series shall be represented by a single certificate registered in the name of the nominee of the Securities Depository unless otherwise required by law or unless there is no Securities Depository. If there is no Securities Depository, at the Corporation's option and upon its receipt of such documents as it deems appropriate, any Preferred Shares may be registered in the Stock Register in the name of the Existing Holder thereof and such Existing Holder thereupon will be entitled to receive certificates therefor and required to deliver certificates therefor upon transfer or exchange thereof.

12. Securities Depository; Stock Certificates. (a) If there is a Securities Depository, one certificate for all of the Preferred Shares of each series shall be issued to the Securities Depository and registered in the name of the Securities Depository or its nominee. Additional certificates may be issued as necessary to represent Preferred Shares. All such certificates shall bear a legend to the effect that such certificates are issued subject to the provisions restricting the transfer of Preferred Shares contained in these Articles Supplementary. Unless the Corporation shall have elected, during a Non-Payment Period, to waive this requirement, the Corporation will also issue stop-transfer instructions to the Auction Agent for the Preferred Shares. Except as provided in paragraph (b) below, the Securities Depository or its nominee will be the Holder, and no existing Holder shall receive certificates representing its ownership interest in such shares.

(b) If the Applicable Rate applicable to all Preferred Shares of a series shall be the Non- Payment Period Rate or there is no Securities Depository, the Corporation may at its option issue one or more new certificates with respect to such shares (without the legend referred to in paragraph 12(a)) registered in the names of the Existing Holders or their nominees and rescind the stop-transfer instructions referred to in paragraph 12(a) with respect to such shares.

13. Interpretations. The Board of Directors may interpret the provisions of these Articles Supplementary to resolve any inconsistency or ambiguity, remedy any formal defect or make any other change or modification that does not adversely affect the rights of Existing Holders of Preferred Shares."

SECOND: The amendment to the charter of the Corporation set forth in these Articles of Amendment was advised by the Board of Directors of the Corporation and approved by the stockholders of the Corporation at a special meeting of the stockholders of the Corporation held on July 13, 1994.

THIRD: The amendment to the charter of the Corporation set forth in these Articles of Amendment does not increase the authorized capital stock of the Corporation.

IN WITNESS WHEREOF, the Corporation has caused these Articles of Amendment to be executed by its President and its corporate seal to be affixed hereto and attested to by its Secretary as of the 13th day of July, 1994.

(2) Not applicable

(3) Not applicable

(4) Not applicable

(5) Registrant undertakes that:

(a) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as a part of a registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant under Rule 497(h) under the Securities Act of 1933 shall be deemed to be a part of this Registration Statement as of the time it was declared effective.

(b) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of the securities at that time shall be deemed to be the initial bona fide offering thereof.

(6) Registrant undertakes to send by first class mail or other means designed to ensure equally prompt delivery, within two business days of receipt of a written or oral request, any Statement of Additional Information.

(7) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding (is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(2) (a) The Board of Directors of the Corporation is authorized to classify or to reclassify, from time to time, any unissued shares of stock of the Corporation, whether now or thereafter authorized, by setting, changing or eliminating the preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications, or terms and conditions of or rights to require redemption of the stock.

(b) Without limiting the generality of the foregoing, the dividends and distributions or other payments with respect to the stock of the Corporation, and with respect to each class that hereafter may be created, shall be in such amount as may be declared from time to time by the Board of Directors, and such dividends and distributions may vary from class to class to such extent and for such purposes as the Board of Directors may deem appropriate, including, but not limited to, the purpose of complying with requirements of regulatory or legislative authorities.

(c) Until such time as the Board of Directors shall provide otherwise pursuant to the authority granted in this section (2) all the authorized shares of the Corporation are designated as Common Stock. Shares of the Common Stock and the holders thereof, and shares of any class and the holders thereof, shall be subject to the following provisions, provided, however, that if no shares of any class other than Common Stock are outstanding, the shares of the Common Stock and the holders thereof shall nevertheless be subject to the following provisions except to the extent that such provisions are by their terms applicable only when shares of two or more classes are outstanding.

(3) The net asset value of each share of the Corporation's capital stock issued, sold or purchased at net asset value shall be the current net asset value per share as determined in accordance with procedures adopted from time to time by the Board of Directors which comply with the 1940 Act.

(4) Shares of each class of stock shall be entitled to such dividends or distributions, in stock or in cash or both, as may be declared from time to time by the Board of Directors, acting in its sole discretion, with respect to such class.

(5) In the event of the liquidation or dissolution of the Corporation, the holders of the Common Stock of the Corporation's stock shall be entitled to receive all the assets of the Corporation not attributable to other classes of stock through any preference. The assets so distributable to the stockholders shall be distributed among such stockholders in proportion to the number of shares of that class held by them and recorded on the books of the Corporation.

(6) Unless otherwise expressly provided in these Article of Incorporation, including any Articles Supplementary creating any class of capital stock, on each matter submitted to a vote of stockholders, each holder of a share of capital stock of the Corporation shall be entitled to one vote for each share standing in such holder's name on the books of the Corporation, irrespective of the class thereof, and all shares of all classes of capital stock shall vote together as a single class; provided, however, that as to any matter with respect to which a separate vote of any class is required by the 1940 Act or any rules, regulations or orders issued thereunder, or the Maryland General Corporation law, such requirement as to a separate vote by that class shall apply in lieu of a vote of all classes voting together as a single class as described above.

(8) All shares purchased by the Corporation shall constitute authorized but unissued shares and the number of the authorized shares of stock of the Corporation shall not be reduced by the number of any shares purchased by it. Unless and until their classification is changed in accordance with section (2) of this Article V, all shares of capital stock so purchased shall continue to belong to the same class to which they belonged at the time of their purchase.

(9) The Corporation may issue shares of stock in fractional denominations to the same extent as its whole shares, and shares in fractional denominations shall be shares of capital stock having proportionately to the respective fractions represented thereby all the rights of whole shares, including without limitation, the right to vote, the right to receive dividends and distributions, and the right to participate upon liquidation of the Corporation, but excluding the right to receive a stock certificate representing fractional shares.

(10) All persons who shall acquire capital stock or other securities of the Corporation shall acquire the same subject to the provisions of these Articles of Incorporation and the By-Laws of the Corporation, as each may be amended from time to time.

ARTICLE VI

PROVISIONS FOR DEFINING, LIMITING AND
REGULATING CERTAIN POWERS OF THE CORPORATION
AND OF THE DIRECTORS AND STOCKHOLDERS

(1) The number of directors of the Corporation shall initially be two (2), which number may be increased by or pursuant to the By-Laws of the Corporation but shall never be less than two (2), unless the Corporation has three (3) or more stockholders during which time the number of directors shall never be less than three (3). In addition, and notwithstanding the preceding sentence, the number of the Corporation's directors shall be increased by or pursuant to the Corporation's By-Laws to a number greater than or equal to three prior to or at the Corporation's first annual meeting of stockholders (the "initial annual meeting"). The names of the persons who shall act as directors until the initial annual meeting and until their successors are duly elected and qualify are:

Ralph L. Schlosstein
Laurence D. Fink

Beginning with the initial annual meeting, the directors shall be divided into three classes, designated Class I, Class II and Class III. Each class shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the entire Board of Directors. At the initial annual meeting of stockholders, Class I directors shall be elected for a one-year term, Class II directors for a two-year term and Class III directors for a three-year term. At each annual meeting of stockholders beginning with the annual meeting of stockholders next succeeding the initial annual meeting, successors to the class of directors whose term expires at that annual meeting shall be elected for a three-year term. A director elected at an annual meeting shall hold office until the annual meeting for the year in which his term expires and until his successor shall be elected and shall qualify, subject, however, to prior death, resignation, retirement, disqualification or removal from office. If the number of directors is changed, any increase or decrease shall be apportioned among the classes, as of the annual meeting of stockholders next succeeding any such change, so as to maintain a number of directors in each class as nearly equal as possible. In no case shall a decrease in the number of directors shorten the term of any incumbent director. Any vacancy on the Board of Directors that results from an increase in the number of directors may be filled by a majority of the entire Board of Directors, provided that a quorum is present, and any other vacancy occurring in the Board of Directors may be filled by a majority of the directors then in office whether or not sufficient to constitute a quorum, or by a sole remaining director; provided, however, that if the stockholders of any class of the Corporation's capital stock are entitled separately to elect one or more directors, a majority of the remaining directors elected by that class or the sole remaining director elected by that class may fill any vacancy among the number of directors elected by that class. A director elected by the Board of Directors to fill any vacancy in the Board of Directors shall serve until the next annual meeting of stockholders and until his successor shall be elected and shall qualify, subject, however, to prior death, resignation, retirement, disqualification or removal from office. At any annual meeting of stockholders, any director elected to fill any vacancy in the Board of Directors that has arisen since the preceding annual meeting of stockholders (whether or not any such vacancy has been filled by election of a new director by the Board of Directors) shall hold office for a term which coincides with the remaining term of the class to which such directorship was previously assigned, if such vacancy arose other than by an increase in the number of directors, and until his successor shall be elected and shall qualify. In the event such vacancy arose due to an increase in the number of directors, any director so elected to fill such vacancy at an annual meeting shall hold office for a term which coincides with that of the class to which such directorship has been apportioned as heretofore provided, and until his successor shall be elected and shall qualify. A director may be removed for cause only, and not without cause, and only by action taken by the holders of at least seventy-five percent (75%) of the shares of capital stock then entitled to vote in an election of such director.

(2) The Board of Directors of the Corporation is hereby empowered to authorize the issuance from time to time of shares of capital stock, whether now or hereafter authorized, for such consideration as the Board of Directors may deem advisable, subject to such limitations as may be set forth in these Articles of Incorporation or in the By-Laws of the Corporation or in the Maryland General Corporation Law or the 1940 Act.

(3) Each person who at any time is or was a director or officer of the Corporation shall be indemnified by the Corporation to the fullest extent permitted by the Maryland General Corporation Law as it may be amended or interpreted from time to time, including the advancing of expenses, subject to any limitations imposed by the 1940 Act and the Rules and Regulations promulgated thereunder. Furthermore, to the fullest extent permitted by Maryland law, as it may be amended or interpreted from time to time, subject to the limitations imposed by the 1940 Act and the Rules and Regulations promulgated thereunder, no director or officer of the Corporation shall be personally liable to the Corporation or its stockholders. No amendment of the Charter of the Corporation or repeal of any of its provisions shall limit or eliminate any of the benefits provided to any person who at any time is or was a director or officer of the Corporation under this Section in respect of any act or omission that occurred prior to such amendment or repeal.

(4) The Board of Directors of the Corporation shall have the exclusive authority to make, alter or repeal from time to time any of the By-Laws of the Corporation except any particular By-Law which is specified as not subject to alteration or repeal by the Board of Directors, subject to the requirements of the 1940 Act and the Rules and Regulations promulgated thereunder.

ARTICLE VII

DENIAL OF PREEMPTIVE RIGHTS

No stockholder of the Corporation shall by reason of his holding shares of capital stock have any preemptive or preferential right to purchase or subscribe to any shares of capital stock of the Corporation, now or hereafter authorized, or any notes, debentures, bonds or other securities convertible into shares of capital stock, now or hereafter to be authorized, whether or not the issuance of any such shares of capital stock, or notes, debentures, bonds or other securities would adversely affect the dividend or voting rights of such stockholder; and the Board of Directors may issue shares of any Class or capital stock of the Corporation, or any notes, debentures, bonds, or other securities convertible into shares of any class of capital stock of the Corporation, either, whole or in part, to the existing stockholders.

ARTICLE VIII

CERTAIN VOTES OF STOCKHOLDERS

(1) Except as otherwise provided in these Articles of Incorporation and notwithstanding any provision of the Maryland General Corporation Law (other than Sections 3-601 through 3-603 of the Maryland General Corporation Law or any successors thereto) requiring approval by the stockholders (or any class of stockholders) of any action by the affirmative vote of a greater proportion than a majority of the votes entitled to be cast on the matter, any such action may be taken or authorized upon the concurrence of a majority of the number of votes entitled to be cast thereon (or a majority of the number of votes entitled to be cast thereon as a separate class).

(2) Notwithstanding the terms of Section 3-603(e)(1)(iv) of the Maryland General Corporation Law (or any successor thereto) and the provisions of Section (1) of this Article VIII, the Corporation hereby expressly elects to be subject to the requirements of Section 3-602 of the Maryland General Corporation Law. The amendment, alteration, modification, or repeal of this
Section (2) of Article VIII of these Articles of Incorporation shall require the vote specified in Section 3-602 of the Maryland General Corporation law.

ARTICLE IX

DETERMINATION BINDING

Any determination made in good faith, so far as accounting matters are involved, in accordance with accepted accounting practice pursuant by or pursuant to the authority of the direction of the Board of Directors, as to the amount of assets, obligations or liabilities of the Corporation, as to the amount of net income of the Corporation from dividends and interest for any period or amounts at any time legally available for the payment of dividends, as to the amount of any reserves or charges set up and the propriety thereof, as to the time of or purpose for creating reserves or as to the use, alteration or cancellation of any reserves or charges (whether or not any obligation or liability for which such reserves or charges shall have been created, shall have been paid or discharges or shall be then or thereafter be required to be paid or discharged ), as to the price of any security owned by the Corporation or as to any other matters relating to the issuance, sale, redemption or other acquisition or disposition of securities or shares of capital stock of the Corporation, and any reasonable determination made in good faith by the Board of Directors shall be final and conclusive, and shall be binding upon the Corporation and all holders of its capital stock, past, present and future, and shares of the capital stock of the Corporation are issued and sold on the condition and understanding, evidenced by the purchase of shares of capital stock or acceptance of share certificates, that any and all such determinations shall be binding as aforesaid. No provision of these Articles of Incorporation shall be effective to (a) require a waiver of compliance with any provision of the Securities Act of 1933, as amended, or the 1940 Act, or of any valid rule, regulation or order of the Securities and Exchange Commission thereunder or (b) protect or purport to protect any director or officer of the Corporation against any liability to the Corporation or its security holders to which he would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office.

ARTICLE X

PRIVATE PROPERTY OF STOCKHOLDERS

The private property of stockholders shall not be subject to the payment of corporate debts to any extent whatsoever.

ARTICLE XI

PERPETUAL EXISTENCE

The Corporation shall have perpetual existence.

ARTICLE XII

CONVERSION TO OPEN-END COMPANY

Notwithstanding any other provisions of these Articles of Incorporation or the By-Laws of the Corporation, a favorable vote of a majority of the total number of directors fixed in accordance with the By- Laws of the Corporation and the favorable vote of the holders of at least seventy-five percent (75%) of the shares of capital stock of the Corporation entitled to be voted on the matter shall be required to approve, adopt or authorize an amendment to these Articles of Incorporation that makes the Common Stock or any other class of capital stock a "redeemable security" as that term is defined in the 1940 Act.

The Corporation shall notify the holders of all capital securities of the approval, in accordance with the preceding paragraph of this Article XII, of any amendment to these Articles of Incorporation that makes the Common Stock a "redeemable security" (as that term is defined in the 1940 Act) no later than (30) days prior to the date of filing of such amendment with the Department of Assessments and Taxation (or any successor agency) of the State of Maryland; such amendment may not be so filed, however, until the later of (a) ninety (90) days following the date of approval of such amendment by the holders of capital securities in accordance with the preceding paragraph of this Article XII and (b) the next January 1 or July 1, whichever is sooner, following the date of such approval by holders of capital securities.

ARTICLE XIII

AMENDMENT

The Corporation reserves the right to amend, alter, change, or repeal any provision contained in these Articles of Incorporation, in the manner now or hereafter prescribed by statute, and all rights conferred upon stockholders herein are granted subject to this reservation.
Notwithstanding any other provisions of these Articles of Incorporation or the By-laws of the Corporation (and by law, these Articles of Incorporation or the By-Laws of the Corporation), the amendment or repeal of Section (1),
Section (3), or Section (4) of Article VI, Section (1) of Article VIII, Article X, Article XI, Article XII or this Article XIII of these Articles of Incorporation shall require the affirmative vote of the holders of at least seventy-five percent (75%) of the shares then entitled to be voted on the matter.

IN WITNESS WHEREOF, the undersigned incorporator of the BlackRock Investment Quality Municipal Trust Inc. hereby executes the foregoing Articles of Incorporation and acknowledges the same to be his act and further acknowledges that, to the best of his knowledge, the matters and facts set forth therein are true in all material respects under the penalties of perjury.

When the Corporation buys a Municipal Obligation and agrees to sell it to another party at a future date and the long-term debt of such other party is rated at least A2 and the transaction has a term of 30 days or less, the cash to be received by the Corporation will be counted as a Moody's Eligible Asset; otherwise such Municipal Obligation will be counted as a Moody's Eligible Asset to the extent it satisfies Moody's current guidelines.

Commencing on the Initial Dividend Payment Date, with respect to the Series T7 Preferred Shares and Series T28 Preferred Shares, the Applicable Rate for each subsequent Dividend Period or portion thereof (hereinafter referred to as a "Subsequent Dividend Payment Period"), which Subsequent Dividend Payment Period shall commence on a Dividend Payment Date and shall end on the calendar day prior to the next Dividend Payment Date, shall be equal to the lesser of (x) the Maximum Applicable Rate for such Dividend Period or for such Subsequent Dividend Payment Period included herein or (y) the greater of (i) the Minimum Applicable Rate for such Dividend Period or for such Subsequent Dividend Payment Period included therein or (ii) the rate per annum that results for such Dividend Period or Subsequent Dividend Payment Period included therein from implementation of the Auction Procedures including any periodic application of a Spread to a specified Reference Index or Reference Security.

Notwithstanding the foregoing sentence, the Applicable Rate for each Dividend Period commencing during a Non-Payment Period shall be equal to the Non-Payment Period Rate and each Dividend Payment Period for Preferred Shares of any series, commencing after the first day of, and during, a Non-Payment Period shall be a 28-day Dividend Payment period (in the case of the Series T28 Preferred Shares) or a 7-day Dividend Payment Period (in the case of the Series T7 Preferred Shares). Except in the case of the willful failure of the Corporation to pay a dividend on a Dividend Payment Date or to redeem any Preferred Shares on the date set for such redemption, any amount of any dividend due on any Dividend Payment Date, the Corporation has declared such dividend payable on such Dividend Payment Date to the Holders of such Preferred Shares as of 12:00 noon, New York City time, on the Business Day preceding such Dividend Payment Date) or redemption price with respect to any Preferred Shares not paid to such Holders when due may be paid to such Holders in the same form of funds by 12:00 noon, New York City time, on any of the first three Business Days after such Dividend Payment Date or due date, as the case may be, provided that, such amount is accompanied by a late charge calculated for such period of non-payment at the Non-Payment Period Rate applied to the amount of such non-payment based on the actual number of days comprising such period divided by 365. In the case of a willful failure of the corporation to pay a dividend on a Dividend Payment Date or to redeem any Preferred Shares on the date set for such redemption, the preceding sentence shall not apply and the Applicable Dividend Rate for the Dividend Period commencing during the Non-Payment Period resulting from such failure shall be the Non-Payment Period Rate. For the purposes of the foregoing, payment to a person in same-day funds on any Business Day at any time shall be considered equivalent to payment to such person in New York Clearing House (next-day) funds at the same time on the preceding Business Day, and any payment made after 12:00 noon, New York City time, on any Business Day shall be considered to have been made instead in the same form of funds and to the same person before 12:00 noon, New York City time, on the next Business Day.

(ii) The amount of cash dividends per share of Preferred Shares payable (if declared) for any Dividend Payment Period or part thereof shall be computed by multiplying the Applicable Rate for such Dividend Payment Period by a fraction, the numerator of which shall be the number of days in such Dividend Payment Period or part thereof such share was outstanding and the denominator of which shall be 365 (or 360 for a Dividend Period of 365 days or more), multiplying the amount so obtained by $50,000 and rounding the amount so obtained to the nearest cent.

(iii) With respect to each Dividend Period that the Corporation desires to be a Special Dividend Period, the Corporation may, at its sole option and to the extent permitted by law, by telephonic and written notice (a "Request for Special Dividend Period") to the Auction Agent and to each Broker-Dealer, request that the next succeeding Dividend Period for such series of Preferred Shares be a number of days (other than 28 in the case of Series T28 Preferred Shares or 7 in the case of Series T7 Preferred Shares), evenly divisible by seven and specified in such notice, provided that for any Auction occurring after the initial Auction, the Corporation may not give a Request for Special Dividend Period (and any such request shall be null and void) unless Sufficient Clearing Bids were made in the last occurring Auction and unless full cumulative dividends, any amounts due with respect to mandatory redemptions, and any Additional Dividends payable prior to such date have been paid in full. Such Request for Special Dividend Period, in the case of a Dividend Period of 182 days or less, shall be given on or prior to the 4th day but not more than 7 days prior to an Auction Date for the Preferred Shares and, in the case of a Dividend Period of more than 182 days, shall be given on or prior to the 14th day but not more than 28 days prior to an Auction Date for the Preferred Shares. Such Request for Special Dividend Period shall also specify any proposed Bid Requirements. Upon receiving such Request for Special Dividend Period, the Broker-Dealer(s) shall jointly determine whether, given the factors set forth below, it is advisable that the Corporation issue a Notice of Special Dividend Period for the Preferred Shares as contemplated by such Request for Special Dividend Period and, if advisable, the Specific Redemption Provisions and shall give the Corporation and the Auction Agent written notice (a "Response") of such determination by no later than the third day prior to such Auction Date. In making such determination the Broker-Dealer(s) will consider (1) existing short-term and long-term market rates and indices of such short-term and long-term rates, (2) existing market supply and demand for short-term and long-term securities, (3) existing yield curves for short-term and long-term securities comparable to the Preferred Shares, (4) industry and financial conditions which may affect the Preferred Shares, (5) the investment objective of the Corporation and (6) the Dividend Periods and dividend rates at which current and potential beneficial holders of the Preferred Shares would remain or become beneficial holders. If none of the Broker-Dealer(s) give the Corporation and the Auction Agent a Response by such third day or if the Response of all of the Broker- Dealers providing a Response states that given the factors set forth above it is not advisable that the Corporation give a notice of Special Dividend Period for the Preferred Shares, the Corporation may not give a Notice of Special Dividend Period in respect of such Request for Special Dividend Period. In the event the Response of at least one Broker-Dealer does not indicate that it is not advisable that the Corporation give a notice of Special Dividend Period for the Preferred Shares, the Corporation may by no later than the second day prior to such Auction Date give a notice (a "Notice of Special Dividend Period") to the Auction Agent, the Securities Depository and each Broker-Dealer which notice will specify the duration of the Special Dividend Period, the Bid Requirements (if any) applicable to the Auction relating to such Special Dividend Period and Specific Redemption Provisions (if any). The Corporation shall not give a Notice of Special Dividend Period or convert to a Special Dividend Period and, if the Corporation has given a notice of Special Dividend, the Corporation is required to give telephonic and written notice of revocation (a "Notice of Revocation") to the Auction Agent, each Broker-Dealer, and the Securities Depository on or prior to the Business Day prior to the relevant Auction Date if it has not obtained the advice in writing of Moody's and S&P or any Substitute Rating Agency that the proposed Special Dividend Period will not adversely affect their then-current rating on the Preferred Shares or if (w) either the 1940 Act Preferred Shares Asset Coverage is not satisfied or the Corporation shall fail to maintain S&P Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount, in each case on each of the two Valuation Dates immediately preceding the Business Day prior to the relevant Auction Date (and in each case, with respect to Moody's Eligible Assets, using a Moody's Exposure Period equivalent to 14 days longer than normal) on an actual basis and on a pro forma basis giving effect to the proposed Special Dividend Period (using as a pro forma dividend rate with respect to such Special Dividend Period the dividend rate which the Broker Dealers shall advise the Corporation is an approximately equal rate for securities similar to the Preferred Shares with an equal frequency of recalculation of the Reference Index or Reference Security as is utilized by the Corporation with respect to the first Dividend Payment Period within such Special Dividend Period and using as a pro forma Maximum Applicable Rate the highest rate specified in the Notice of Special Dividend Period for the Dividend Payment Periods covering not less than the first 49 days of such proposed Special Dividend Period or, if no such rate is specified in the Notice of Special Dividend Period, the Maximum Applicable Rate resulting by operation of the definition of Special Dividend Period Reference Rate for the Special Dividend Period specified in such Notice of Special Dividend Period), (x) sufficient funds for the payment of dividends payable on the immediately succeeding Dividend Payment Date have not been irrevocably deposited with the Auction Agent by the close of business on third Business Day preceding the related Auction Date, (y) the Broker- Dealer(s) jointly advise the Corporation that after consideration of the factors listed above they have concluded that it is advisable to give a Notice of Revocation or (z) the Corporation has determined to terminate the Special Dividend Period for any reason. If the Corporation is prohibited from giving a Notice of Special Dividend Period as a result of any of the factors enumerated in clause (w), (x), (y) or (z) of the prior sentence or if the Corporation gives a Notice of Revocation with respect to a Notice of Special Dividend Period, the next succeeding Dividend Period will be a 28-day Period (in the case of Series T28 Preferred Shares) or a 7-day Dividend Period the case of Series T7 Preferred Shares) provided that if the then-current Dividend Period in the case of the Series T28 Preferred Shares is a Special Dividend Period of less than 28 days, the next succeeding Dividend Period for such series will be the same length as the current Dividend Period. In addition, in the event Sufficient Clearing Bids are not made in the applicable Auction or such Auction is not held for any reason, such next succeeding Dividend Period will be a 28 day Dividend Period (in the case of Series T28 Preferred Shares) or a 7-day Dividend Period (in the case of Series T7 Preferred Shares) and the Corporation may not again give a Notice of Special Dividend Period of the Preferred Shares (and any such attempted notice shall be null and void) until Sufficient Clearing bids have been made in an Auction with respect to a 28-day Dividend Period (in the case of Series T28 Preferred Shares) or a 7-day Dividend Period (in the case of Series T7 Preferred Shares).

(d) (i) Holders shall not be entitled to any dividends, whether payable in cash, property or stock, in excess of full cumulative dividends, as herein provided, on the Preferred Shares. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment on the Preferred Shares that may be in arrears.

(ii) For so long as any share of the Preferred Shares is outstanding, the Corporation shall not declare, pay or set apart for payment any dividend or other distribution (other than a dividend or distribution paid in shares of, or options, warrants or rights to subscribe for or purchase, Common Stock or other stock, if any, ranking junior to the Preferred Shares as to dividends or upon liquidation) in respect of the Common Stock or any other stock of the Corporation ranking junior to or on a parity with the Preferred Shares as to dividends or upon liquidation, or call for redemption, redeem, purchase or otherwise acquire for consideration any shares of the Common Stock or any other such junior stock (except by conversion into or exchange for stock of the Corporation ranking junior to the Preferred Shares as to dividends and upon liquidation) or any other such Parity Stock (except by conversion into or exchange for stock of the Corporation ranking junior to or on a parity with the Preferred Shares as to dividends and upon liquidation), unless (A) immediately after such transaction, the Corporation shall have Moody's Eligible Assets and S&P Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount and the Corporation shall maintain the 1940 Act Preferred Shares Asset Coverage, (B) full cumulative dividends on Preferred Shares and shares of Other Preferred Shares due on or prior to the date of the transaction have been declared and paid or shall have been declared and sufficient funds for the payment thereof deposited with the Auction Agent, (C) any Additional Dividend required to be paid under paragraph 2(e) below on or before the date of such declaration or payment has been paid and (D) the Corporation has redeemed the full number of Preferred Shares required to be redeemed by any provision for mandatory redemption contained herein.

(e) Each dividend shall consist of (i) cash at the at the Applicable Rate and (ii) an uncertificated right (a "Right") to receive an Additional Dividend (as defined below). Each Right shall thereafter be independent of the share or Preferred Shares on which the dividend was paid. The Corporation shall cause to be maintained a record of each Right received by the respective Holders. The Corporation shall not be required to recognize any transfer of a Right.

If, in the case of a Dividend Period of 28 days or fewer, the Corporation retroactively allocates any net capital gains or other taxable income to Preferred Shares without having given advance notice thereof to the Auction Agent as described in paragraph 2(f) hereof (the amount of such allocation referred to herein as a "Retroactive Taxable Allocation") solely by reason of the fact that such allocation is made as a result of the redemption of all or a portion of the outstanding Preferred Shares or the liquidation of the Corporation, the Corporation will, within 90 days (and generally within 60 days) after the end of the Corporation's fiscal year for which a Retroactive Taxable Allocation is made, provide notice thereof to the Auction Agent and to each holder of a Right applicable to such Preferred Shares (initially Cede & Co. as nominee of The Depository Trust Company) during such fiscal year at such holder's address as the same appears or last appeared on the Stock Books of the Corporation. The Corporation will, within 30 days after such notice is given to the Auction Agent, pay to the Auction Agent (who will then distribute to such holders of Rights), out of funds legally available therefor, an amount equal to the aggregate Additional Dividend with respect to all Retroactive Taxable Allocations made to such holders during the fiscal year in question.

If the Corporation, in the case of a Dividend Period of 35 days or more, makes a Retroactive Taxable Allocation to a dividend paid on Preferred Shares, the Corporation will, within 90 days (and generally within 60 days) after the end of the Corporation's fiscal year for which a Retroactive Taxable Allocation is made, provide notice thereof to the Auction Agent and to each holder of a Right applicable to such Preferred Shares (initially Cede & Co. as nominee of The Depository Trust Company) during such fiscal year at such holder's address as the same appears or last appeared on the Stock Books of the Corporation. The Corporation will, within 30 days after such notice is given to the Auction Agent, pay to the Auction Agent (who will then distribute to such holders of Rights), out of funds legally available therefor, an amount equal to the aggregate Additional Dividend with respect to all Retroactive Taxable Allocations made to such holders during the fiscal year in question.

An "Additional Dividend" means payment to a holder of Preferred Shares of an amount which, when taken together with the aggregate amount of Retroactive Taxable Allocations allocated to such holder with respect to the fiscal year in question, would cause such holder's dividends from the aggregate of both the Retroactive Taxable Allocations and the Additional Dividend to be equal to the dollar amount of the dividends which would have been received and retained by such holder if the Retroactive Taxable Allocations had not been made. Such Additional Dividend shall be calculated (i) without consideration being given to the time value of money; (ii) assuming that no holder of Preferred Shares is subject to the Federal alternative minimum tax with respect to dividends received from the Corporation; and (iii) assuming that each Retroactive Taxable Allocation would be taxable in the hands of each holder of Preferred Shares at the maximum marginal combined regular Federal income tax rate applicable to individuals or corporations, whichever is greater, in effect during the fiscal year in question.

(f) Whenever the Corporation intends to include any net capital gains or other taxable income in any dividend on Preferred Shares the Applicable Rate for which will be established at the next succeeding Auction, the Corporation will, in the case of a Dividend Period of 28 days or fewer, and may, in the case of a Dividend Period of 35 days or more, notify the Auction Agent of the amount to be so included at least five Business Days prior to the Auction Date on which the Applicable Rate for such dividend is to be established. If, in the case of a Dividend Period of 28 days or fewer, the Corporation retroactively allocates any net capital gains or other taxable income to a dividend paid on Preferred Shares without having given advance notice thereof to the Auction Agent as described in paragraph 2(f) hereof solely by reason of the fact that such allocation is made as a result of the redemption of all or a portion of the outstanding Preferred Shares or the liquidation of the Corporation, the Corporation will make certain payments to holders of Preferred Shares to offset the tax effect thereof. If, in the case of a Dividend Period of 35 days or more, the Corporation allocates any net capital gains or other taxable income to a dividend paid on Preferred Shares without having given advance notice thereof to the Auction Agent as described in Paragraph 2(f) hereof, the Corporation will make certain payments to holders of Preferred Shares to offset the tax effect thereof.

(g) No fractional share of Preferred Shares shall be issued.

3. Liquidation Rights. Upon any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, the Holders shall be entitled to receive, out of the assets of the Corporation available for distribution to shareholders, before any distribution or payment is made upon any Common Stock or any other capital stock ranking junior in right of payment upon liquidation to the Preferred Shares, the sum of $50,000 per share plus accumulated but unpaid dividends (whether or not earned or declared) thereon plus the premium, if any, resulting from the designation of a Premium Call Period to the date of distribution, and after such payment the holders of Preferred Shares will be entitled to no other payments other than Additional Dividends as provided in paragraph 2(e) hereof. If upon any liquidation, dissolution or winding up of the Corporation, the amounts payable with respect to the Preferred Shares and any other outstanding class or series of Preferred Stock of the Corporation ranking on a parity with the Preferred Shares as to payment upon liquidation are not paid in full, the Holders and the holders of such other class or series will share ratably in any such distribution of assets in proportion to the respective preferential amounts to which they are entitled. After payment of the full amount of the liquidating distribution to which they are entitled, the Holders will not be entitled to any further participation in any distribution of assets by the Corporation except for any Additional Dividends. A consolidation or merger of the Corporation with or into any other corporation or corporations or a sale, whether for cash, shares of stock, securities or properties, of all or substantially all or any part of the assets of the Corporation shall not be deemed or construed to be a liquidation, dissolution or winding up of the Corporation.

4. Redemption. (a) Preferred Shares shall be redeemable by the Corporation as provided below:

(i) To the extent permitted under the 1940 Act and Maryland law, upon giving a Notice of Redemption, the Corporation at its option may redeem Preferred Shares, in whole or in part, out of funds legally available therefor, at the Optional Redemption Price per share, on any Dividend Payment Date; provided, however, that no Preferred Shares shall be subject to optional redemption during a Non-Call Period. In addition, holders of Preferred Shares which are redeemed shall be entitled to receive Additional Dividends to the extent provided herein. The Corporation may not give a Notice of Redemption relating to an optional redemption as described in this paragraph 4(a)(i) or effect an optional redemption unless, at the time of giving such Notice of Redemption or effecting such optional redemption, the Corporation has available Deposit Securities with maturity or tender dates not later than the day preceding the applicable redemption date and having a value not less than the amount due to Holders by reason of the redemption of their Preferred Shares on such redemption date and, if as a result of such optional redemption, the Corporation would fail to maintain S&P Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value equal to the Preferred Shares Basic Maintenance Amount.

(ii) The Corporation shall redeem, out of funds legally available therefor, at the Mandatory Redemption Price per share, Preferred Shares to the extent permitted under the 1940 Act and Maryland law, on a date fixed by the Board of Directors, if the Corporation fails to maintain Moody's Eligible Assets and S&P Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount as provided in paragraph 7(a) or to satisfy the 1940 Act Preferred Shares Asset Coverage as provided in paragraph 6 and such failure is not cured on or before the Preferred Shares Basic Maintenance Cure Date or the 1940 Act Cure Date (herein respectively referred to as the "Cure Date"), as the case may be. In addition, holders of Preferred Shares so redeemed shall be entitled to receive Additional Dividends to the extent provided herein. The number of Preferred Shares to be redeemed shall be equal to the lesser of (i) the minimum number of Preferred Shares the redemption of which, if deemed to have occurred immediately prior to the opening of business on the Cure Date, would together with all shares of Other Preferred Stock subject to redemption or retirement, result in the Corporation having S&P Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount or satisfaction of the 1940 Act Preferred Shares Asset Coverage, as the case may be, on such Cure Date (provided that, if there is no such minimum number of Preferred Shares and shares of Other Preferred Stock the redemption of which would have such result, all Preferred Shares and shares of Other Preferred Stock then outstanding shall be redeemed), and (ii) the maximum number of Preferred Shares, together with all shares of other Preferred Stock subject to redemption or retirement, that can be redeemed out of funds expected to be legally available therefor on such redemption date. In determining the number of Preferred Shares required to be redeemed in accordance with the foregoing, the Corporation shall allocate the number required to be redeemed which would result in the Corporation having Moody's Eligible Assets and S&P Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount or satisfaction of the 1940 Act Preferred Shares Asset Coverage, as the case may be, pro rata among Preferred Shares, Other Preferred Shares and other Preferred Stock subject to redemption pursuant to provisions similar to those contained in this paragraph 4(a)(ii) provided that, Preferred Shares which may not be redeemed at the option of the Corporation (a) will be subject to mandatory redemption only to the extent that other shares are not available to satisfy the number of shares required to be redeemed and (b) will be selected for redemption in an ascending order of outstanding number of days in the Non-Call Period during which such shares are not subject to optional redemption (with shares with the lowest number of days to be redeemed first) and by lot in the event of shares having an equal number of days in such period. The Corporation shall effect such redemption on a Business Day which is not later than 30 days after such Cure Date, except that if the Corporation does not have funds legally available for the redemption of all of the required number of Preferred Shares and shares of other Preferred Stock which are subject to mandatory redemption or the Corporation otherwise is unable to effect such redemption on or prior to 30 days after such Cure Date, the Corporation shall redeem those Preferred Shares which it is unable to redeem on the earliest practicable date on which it is able to effect such redemption out of funds legally available therefor.

(b) Notwithstanding any other provision of this paragraph 4, no Preferred Shares may be redeemed pursuant to paragraph 4(a)(i) of these Articles Supplementary unless all dividends in arrears on all remaining outstanding shares of Parity Stock shall have been or are being contemporaneously paid or declared and set apart for payment. In the event that less than all the outstanding Preferred Shares are to be redeemed and there is more than one Holder, the shares to be redeemed shall be selected by lot or such other method as the Corporation shall deem fair and equitable.

(c) Whenever Preferred Shares are to be redeemed, the Corporation, not less than 20 or more than 60 days prior to the date fixed for redemption, shall mail a notice ("Notice of Redemption") by first-class mail, postage prepaid, to each Holder of Preferred Shares to be redeemed and to the Auction Agent. The Corporation shall cause the Notice of Redemption also to be published in the eastern and national editions of The Wall Street Journal. The Notice of Redemption to set forth (i) the redemption date, (ii) the amount of the redemption price, (iii) the aggregate number of Preferred Shares to be redeemed, (iv) the place or places where Preferred Shares are to be surrendered for payment of the redemption price, (v) a statement that dividends on the shares to be redeemed shall cease to accumulate on such redemption date (except that holders may be entitled to Additional Dividends) and (vi) the provision of these Articles Supplementary pursuant to which such shares are being redeemed. No defect in the Notice of Redemption or in the mailing or publication thereof shall affect the validity of the redemption proceedings, except as required by applicable law.

If the Notice of Redemption shall have been given as aforesaid and, concurrently or thereafter, the Corporation shall have deposited in trust with the Auction Agent a cash amount equal to the redemption payment for the Preferred Shares to which such Notice of Redemption has been given with irrevocable instructions and authority to pay the redemption price to the Holders of such shares, then upon the date of such deposit or, if no such deposit is made, then upon such date fixed for redemption (unless the Corporation shall default in making the redemption payment), all rights of the Holders of such shares as shareholders of the Corporation by reason of the ownership of such shares will cease and terminate (except their right to receive the redemption price in respect thereof and any additional dividends, but without interest), and such shares shall no longer be deemed outstanding. The Corporation shall be entitled to receive, from time to time, from the Auction Agent the interest, if any, on such moneys deposited with it and the Holders of any shares so redeemed shall have no claim to any of such interest. In case the Holder of any shares so called for redemption shall not claim the redemption payment for his shares within one year after the date of redemption, the Auction Agent shall, upon demand, pay over to the Corporation such amount remaining on deposit and the Auction Agent shall thereupon be relieved of all responsibility to the Holder of such shares called for redemption and such Holder thereafter shall look only to the Corporation for the redemption payment.

5. Voting Rights. (a) General. Except as otherwise provided in the Charter, each Holder of Preferred Shares shall be entitled to one vote for each share held on each matter submitted to a vote of stockholders of the Corporation to which the stockholders are entitled to vote, and the holders of outstanding shares of Preferred Stock, including Preferred Shares, and of shares of Common Stock shall vote together as a single class with respect to all matters on which all stockholders are entitled to vote. Notwithstanding the preceding sentence, at the first annual meeting of stockholders, the holders of outstanding shares of Preferred Stock, including Preferred Shares, represented in person or by proxy shall be entitled as a class, and to the exclusion of the holders of all other securities and classes of capital stock of the Corporation, to elect one Class I director and one Class II director and shall thereafter be so entitled to elect any successors from time to time to the Class I and Class II directors so elected at any meeting of shareholders in which successors are elected. At each meeting of shareholders at which entire classes of Class I and Class II directors are to be elected, or at any meeting at which a successor to a director elected by the holders of Preferred Stock in accordance with this Section is to be elected (including directors elected pursuant to this sentence), the holders of outstanding shares of Preferred Stock, including Preferred Shares, represented in person or by proxy shall be entitled as a class and to the exclusion of the holders of all other securities and classes of capital stock of the Corporation to elect one Class I and one Class II director or to elect such successor. In the event that the Charter is amended to eliminate the classification of the Corporation's Board of Directors, the holders of outstanding shares of Preferred Stock, including Preferred Shares, represented in person or by proxy shall be entitled as a class, and to the exclusion of the holders of all other securities and classes of capital stock of the Corporation, to elect two directors. Subject to paragraph 5(b) hereof, the holders of outstanding shares of capital stock of the Corporation, voting as a single class, shall elect the balance of the directors.

(b) Right to Elect Majority of Board of Directors. During any period in which any one or more of the conditions described below shall exist (such period being referred to herein as a "Voting Period"), the number of directors constituting the Board of Directors shall be automatically increased by the smallest number that, when added to the two directors elected exclusively by the holders of shares of Preferred Stock, would constitute a majority of the Board of Directors as so increased by such smallest number; and the holders of shares of Preferred Stock shall be entitled, voting as a class on a one-vote-per-share basis (to the exclusion of the holders of all other securities and classes of capital stock of the Corporation), to elect such smallest number of additional directors, together with the two directors that such holders are in any event entitled to elect. A Voting Period shall commence:

(i) if at any time accumulated dividends (whether or not earned or declared, and whether or not funds are then legally available in an amount sufficient therefor) on the outstanding Preferred Shares equal to at least two full years' dividends shall be due and unpaid and sufficient cash or specified securities shall not have been deposited with the Auction Agent for the payment of such accumulated dividends; or

(ii) if at any time holders of any Preferred Stock are entitled to elect a majority of the directors of the Corporation under the 1940 Act.

Upon the termination of a Voting Period, the voting rights described in this paragraph 5(b) shall cease, subject always, however, to the revesting of such voting rights in the Holders upon the further occurrence of any of the events described in this paragraph 5(b).

(c) Right to Vote with Respect to Certain Other Matters. So long as any Preferred Shares are outstanding, the Corporation shall not, without the affirmative vote of the holders of a majority of the Outstanding shares of Preferred Stock outstanding at the time, in person or by proxy, at a meeting (voting separately as one class) or by the unanimous written consent of the holders of all Outstanding shares of Preferred Stock: (i) authorize, create or issue, or increase the authorized or issued amount of, any class or series of stock ranking prior to or on a parity with any series of Preferred Stock with respect to payment of dividends or the distribution of assets on liquidation, or increase the authorized amount of Preferred Shares or any other Preferred Stock (except that, notwithstanding the foregoing, but subject to the provisions of
Section 13 of the 1940 Act, the Board of Directors, without the vote or consent of the Holders of Preferred Shares, may from time to time authorize, create and issue, and may increase the authorized or issued amount of, classes or series of Preferred Stock, including Preferred Shares, ranking on a parity with the Preferred Shares with respect to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Corporation, subject to continuing compliance by the Corporation with 1940 Act Preferred Shares Asset Coverage and Preferred Shares Basic Maintenance Amount requirements, provided that the Fund obtains written confirmation from Moody's (if Moody's is then rating Preferred Shares), S&P (if S&P is then rating Preferred Shares) or any Substitute Rating Agency (if any such Substitute Rating Agency is then rating Preferred Shares) that the issuance of such class or series would not impair the rating then assigned by such rating agency to the Preferred Shares), (ii) amend, alter or repeal the provisions of the Charter whether by merger, consolidation or otherwise, so as to adversely affect any of the contract rights expressly set forth in the Charter of holders of Preferred Shares or any Other Preferred Stock, (iii) authorize the Corporation's conversion from a closed-end to an open-end investment company as defined in Section 5(a) of the 1940 Act, or (iv) amend the provisions of the Charter which provide for the classification of the Board of Directors of the Corporation into three classes, each with a term of office of three years with only one class of directors standing for election in any year (presently Article VI of the Charter). To the extent permitted under the 1940 Act, the Corporation shall not approve any of the actions set forth in clause (i) or (ii) which adversely affects the contract rights expressly set forth in the Charter of a Holder of shares of a series of Preferred Shares differently than those of a Holder of shares of any other series of Preferred Shares without the affirmative vote of the holders of at least a majority of the Preferred Shares of each series adversely affected and Outstanding at such time, in person or by proxy, at a meeting (each such adversely affected series voting separately as a class) or by the unanimous written consent of the holders of all Outstanding shares of Preferred Stock. The Corporation shall notify Moody's and S&P 10 Business Days prior to any such vote described in clauses (i) and (ii). Unless a higher percentage is provided for under the Charter, the affirmative vote of the holders of a majority of the Outstanding shares of Preferred Stock, including Preferred Shares, voting together as a single class, will be required to approve any plan of reorganization (including bankruptcy proceedings) adversely affecting such shares or any action requiring a vote of security holders under Section 13(a) of the 1940 Act. The class vote of holders of shares of Preferred Stock, including Preferred Shares, described above will in each case be in addition to a separate vote of the requisite percentage of shares of Common Stock and shares of Preferred Stock, including Preferred Shares, voting together as a single class necessary to authorize the action in question. Notwithstanding the preceding sentence, to the extent permitted by Maryland General Corporation Law, no vote of holders of Common Stock, either separately or together with holders of Preferred Shares as a single class, shall be necessary to take the actions contemplated by clauses (i) and (ii) of the first sentence of this Section 5(c) and the holders of Common Stock shall not be entitled to vote in respect of such matters, unless, in the case of the actions contemplated by clause (ii) of the first sentence of this section 5(c), the action would adversely affect the contract rights expressly set forth in the Charter of the holders of Common Stock.

(d) Voting Procedures.

(i) As soon as practicable after the accrual of any right of the Holders of shares of Preferred Stock to elect additional directors as described in paragraph 5(b) above, the Corporation shall notify the Secretary of the Corporation and instruct the Secretary to call a special meeting of such Holders, by mailing a notice of such special meeting to such Holders, such meeting to be held not less than 10 nor more than 20 days after the date of mailing of such notice. If the Secretary of the Corporation does not call such a special meeting, it may be called by Holders of at least 25% of the votes entitled to be cast at such meeting on like notice. The record date for determining the Holders entitled to notice of and to vote at such special meeting shall be the close of business on the fifth Business Day preceding the day on which such notice is mailed. At any such special meeting and at each meeting held during a Voting Period, such Holders, voting together as a class (to the exclusion of the holders of all other securities and classes of capital stock of the Corporation), shall be entitled to elect the number of directors prescribed in paragraph 5(b) above on a one-vote-per-share basis. At any such meeting or adjournment thereof in the absence of a quorum, a majority of such holders present in person or by proxy shall have the power to adjourn the meeting without notice, other than by an announcement at the meeting, to a date not more than 120 days after the original record date.

(ii) For purposes of determining any rights of the Holders to vote on any matter or the number of shares required to constitute a quorum, whether such right is created by these Articles Supplementary, by the other provisions of the Charter, by statute or otherwise, a share of Preferred Shares which is not outstanding shall not be counted.

(iii) The terms of office of all persons who are directors of the Corporation at the time of a special meeting of Holders and holders of other Preferred Stock to elect directors shall continue, notwithstanding the election at such meeting by the Holders and such other holders of the number of directors that they are entitled to elect, and the persons so elected by the Holders and such other holders, together with the two incumbent directors elected by the Holders and such other holders of Preferred Stock and the remaining incumbent directors elected by the holders of the Common Stock and Preferred Stock, shall constitute the duly elected directors of the Corporation.

(iv) The terms of office of the additional directors elected by the Holders and holders of other Preferred Stock pursuant to paragraph 5(b) above shall terminate on the earliest date permitted by the Maryland General Corporation Law following the termination of a Voting Period, the remaining directors shall constitute the directors of the Corporation and the voting rights of the Holders and such other holders to elect additional directors pursuant to paragraph 5(b) above shall cease, subject to the provisions of the last sentence of paragraph 5(b)(ii).

(e) Exclusive Remedy. Unless otherwise required by law, the Holders of Preferred Shares shall not have any relative rights or preferences or other special rights other than those specifically set forth herein. The Holders of Preferred Shares shall have no preemptive rights or rights to cumulative voting. In the event that the Corporation fails to pay any dividends on the Preferred Shares, the exclusive remedy of the Holders shall be the right to vote for directors pursuant to the provisions of this paragraph 5.

(f) Notification to Moody's and S&P. In the event a vote of Holders of Preferred Shares is required pursuant to the provisions of
Section 13(a) of the 1940 Act, the Corporation shall, not later than ten business days prior to the date on which such vote is to be taken, notify Moody's and S&P that such vote is to be taken and the nature of the action with respect to which such vote is to be taken. Upon completion of any such vote, the Corporation shall notify Moody's and S&P as to the result of such vote.

6. 1940 Act Preferred Shares Asset Coverage. The Corporation shall maintain, as of the last Business Day of each month in which any share of Preferred Shares is outstanding, the 1940 Act Preferred Shares Asset Coverage.

7. Preferred Shares Basic Maintenance Amount. (a) The Corporation shall maintain, on each Valuation Date, and shall verify to its satisfaction that it is maintaining on such Valuation Date, (i) Moody's Eligible Assets having an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount and (ii) S&P Eligible Assets having an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount. Upon any failure to maintain the required Discounted Value, the Corporation will use its best efforts to alter the composition of its portfolio to reattain the Preferred Shares Basic Maintenance Amount on or prior to the Preferred Shares Basic Maintenance Cure Date.

(b) On or before 5:00 p.m., New York City time, on the third Business Day after a Valuation Date on which the Corporation fails to satisfy the Preferred Shares Basic Maintenance Amount, the Corporation shall complete and deliver to the Auction Agent, Moody's and S&P a complete Preferred Shares Basic Maintenance Report as of the date of such failure, which shall be deemed to have been delivered to the Auction Agent if the Auction Agent receives a copy or telecopy, telex or other electronic transcription thereof and on the same day the Corporation mails to the Auction Agent for delivery on the next Business Day the complete Preferred Shares Basic Maintenance Report. The Corporation shall also give a notice of cure of its failure to satisfy the Preferred Shares Basic Maintenance Amount along with the complete Preferred Shares Basic Maintenance Report to the Auction Agent, Moody's and S&P within three Business Days of its determination that it has satisfied such requirement following any period during which it has failed to satisfy such requirement. The Corporation will also deliver a Preferred Shares Basic Maintenance Report to the Auction Agent as of (i) the fifteenth day of each month (or, if such day is not a Business Day, the next succeeding Business Day) and (ii) the last Business Day of each month, in each case on or before the third Business Day after such day. The Corporation will also deliver a Preferred Shares Basic Maintenance Report to Moody's or S&P, as the case may be, for each Valuation Date that the Discounted Value of Moody's Eligible Assets or S&P Eligible Assets is less than or equal to 125% of the Preferred Shares Basic Maintenance Amount, provided, however, that if the Valuation Date is every day that is a Business Day, the Corporation will deliver a Preferred Shares Basic Maintenance Report to Moody's or S&P, as the case may be, for each Valuation Date that the Discounted Value of Moody's Eligible Assets or S&P Eligible Assets is less than or equal to 105% of the Preferred Shares Basic Maintenance Amount. The Corporation will deliver a Preferred Shares Basic Maintenance Report to Moody's upon request and when the Corporation redeems any shares of Common Stock. The Corporation will deliver a Preferred Shares Basic Maintenance Report to S&P upon request. A failure by the Corporation to deliver a Preferred Shares Basic Maintenance Report under this paragraph 7(b) shall be deemed to be delivery of a Preferred Shares Basic Maintenance Report indicating the Discounted Value for S&P Eligible Assets and Moody's Eligible Assets of the Corporation is less than the Preferred Shares Basic Maintenance Amount, as of the relevant Valuation Date.

(c) Within ten Business Days after the date of delivery of the Preferred Shares Basic Maintenance Report and a Certificate of Minimum Liquidity in accordance with paragraph 7(b) above relating to a Quarterly Valuation Date, the Corporation shall cause the Independent Accountant to confirm in writing the Auction Agent. Moody's and S&P (i) the mathematical accuracy of the calculations reflected in such Report (and in any other Preferred Shares Basic Maintenance Report, randomly selected by the Independent Accountant, that was delivered by the Corporation during the quarter ending on such Quarterly Valuation Date) and (with respect to S&P only while S&P is rating the Preferred Shares) such Certificate, (ii) that, in such Report (and in such randomly selected Report), the Corporation correctly determined the assets of the Corporation which constitute S&P Eligible Assets or Moody's Eligible Assets, as the case may be, at such Quarterly Valuation Date in accordance with these Articles Supplementary,
(iii) that, in such Report (and in such randomly selected Report), the Corporation determined whether the Corporation had, at such Quarterly Valuation Date (and at the Valuation Date addressed in such randomly- selected Report) in accordance with these Articles Supplementary, S&P Eligible Assets of an aggregate Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount and Moody's Eligible Assets of an aggregate Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount, (iv) that (with respect o S&P only) in such Certificate, the Corporation determined the Minimum Liquidity Level and the Corporation's Deposit Securities in accordance with these Articles Supplementary, including maturity or tender date, (v) with respect to the S&P rating on Municipal Obligations, the issuer name, issue size and coupon rate listed in such Report and (with respect to S&P only) such Certificate, that the Independent Accountant has requested that S&P verify such information and the Independent Accountant shall provide - listing in its letter of any differences, (vi) with respect to the Moody's ratings on Municipal Obligations the issuer name, issue size and coupon rate listed in such Report and (with respect to S&P only) such Certificate, that such information has been verified by Moody's (in the event such information is not verified by Moody's the Independent Accountant will inquire of Moody's what such information is, and provide a listing in its letter of any differences) and (vii) with respect to the bid or mean price (or such alternative permissible factor used in calculating the Market Value) provided by the custodian of the Corporation's assets to the Corporation for purposes of valuing securities in the Corporation's portfolio, the Independent Accountant has traced the price used in such Report and (with respect to S&P only) such Certificate to the bid or mean price listed in such Report and (with respect to S&P only) such Certificate as provided to the Corporation and verified that such information agrees (in the event such information does not agree, the Independent Accountant will provide a listing in its letter of such differences) (such confirmation is herein called the "Accountant's Confirmation").

(d) Within ten Business Days after the date of delivery to the Auction Agent, S&P and Moody's of a Preferred Shares Basic Maintenance Report in accordance with paragraph 7(b) above relating to any Valuation Date on which the Corporation failed to maintain S&P Eligible Assets with an aggregate Discounted Value and Moody's Eligible Assets with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount, and relating to the Preferred Shares Basic Maintenance Cure Date with respect to such failure, the Independent Accountant will provide to the Auction Agent, S&P and Moody's an Accountant's Confirmation as to such Preferred Shares Basic Maintenance Report.

(e) If any Accountant's Confirmation delivered pursuant to Subparagraph (c) or (d) of this paragraph 7 shows that an error was made in the Preferred Shares Basic Maintenance Report for a particular Valuation Date for which such Accountant's Confirmation was required to be delivered, or shows that a lower aggregate Discounted Value for the aggregate of all S&P Eligible Assets or Moody's Eligible Assets, as the case may be, of the Corporation was determined by the Independent Accountant, the calculation or determination made by such Independent Accountant shall be final and conclusive and shall be binding on the Corporation and the Corporation shall accordingly amend and deliver the Preferred Shares Basic Maintenance Report to the Auction Agent, S&P and Moody's promptly following receipt by the Corporation of such Accountant's Confirmation.

(f) On or before 5:00 p.m., New York City time, on the first Business Day after the Date of Original Issue of the Preferred Shares, the Corporation will complete and deliver to S&P and Moody's a Preferred Shares Basic Maintenance Report as of the close of business on such Date of Original Issue. Within five business days of such Date of Original Issue, the Corporation shall cause the Independent Accountant to confirm in writing to S&P and Moody's (i) the mathematical accuracy of the calculations reflected in such Report and (ii) that the aggregate Discounted Value of S&P Eligible Assets and the aggregate Discounted Value of Moody's Eligible Assets reflected thereon equals or exceeds the Preferred Shares Basic Maintenance Amount reflected thereon.

(g) For so long as Preferred Shares are rated by Moody's, in managing the Corporation's portfolio, the Corporation shall require that the Adviser will not alter the composition of the Corporation's portfolio if, in the reasonable belief of the Adviser, the effect of any such alteration would be to cause the Corporation to have Moody's Eligible Assets with an aggregate Discounted Value, as of the immediately preceding Valuation Date, less than Preferred Shares Basic Maintenance Amount as of such Valuation Date; provided, however, that in the event that, as of the immediately preceding Valuation Date, the aggregate Discounted Value of Moody's Eligible Assets exceeded the Preferred Shares Basic Maintenance Amount by twenty-five percent or less (or, in the event the Valuation Date is every day that is a Business Day, five percent or less), the Adviser will not alter the composition of the Corporation's portfolio in a manner reasonably expected to reduce the aggregate Discounted Value of Moody's Eligible Assets unless the Corporation shall have confirmed that, after giving effect to such alteration, the aggregate Discounted Value of Moody's Eligible Assets would exceed the Preferred Shares Basic Maintenance Amount.

8. Minimum Liquidity Level. (i) For so long as any Preferred Shares are rated by S&P, the Corporation shall be required to have, as of each Valuation Date, Dividend Coverage Assets having in aggregate a value not less than the Dividend Coverage Amount

(ii) As of each Valuation Date as long as any Preferred Shares are rated by S&P, the Corporation shall determine (A) the Market Value of the Dividend Coverage Assets owned by the Corporation as of that Valuation Date, (B) the Dividend Coverage Amount on that Valuation Date, and (C) whether the Minimum Liquidity Level is met as of that Valuation Date. The calculations of the Dividend Coverage Assets, the Dividend Coverage Amount and whether the Minimum Liquidity Level is met shall be set forth in a certificate (a "Certificate of Minimum Liquidity") dated as of the Valuation Date. The Preferred Shares Basic Maintenance Report and the Certificate of Minimum Liquidity may be combined in one certificate. The Corporation shall cause the Certificate of Minimum Liquidity to be delivered to S&P not later than the close of business on the third Business Day after the Valuation Date applicable to such Certificate pursuant to paragraph
7(b). The Minimum Liquidity Level shall be deemed to be met as of any date of determination if the Corporation has timely delivered a Certificate of Minimum Liquidity relating to such date which states that the same has been met and which is not manifestly inaccurate. In the event that a Certificate of Minimum Liquidity is not delivered to S&P when required, the Minimum Liquidity Level shall be deemed not to have been met as of the applicable date.

(iii) If the Minimum Liquidity Level is not met as of any Valuation Date, then the Corporation shall purchase or otherwise acquire Dividend Coverage Assets to the extent necessary so that the Minimum Liquidity Level is met as of the fifth Business Day, provide to S&P a Certificate of Minimum Liquidity setting forth the calculations of the Dividend Coverage Assets and the Dividend Coverage Amount and showing that the Minimum Liquidity Level is met as such fifth Business Day together with a report of the custodian of the Corporation's assets confirming the amount of the Corporation's Dividend Coverage Assets as of such fifth Business Day.

9. Certain Other Restrictions. (a) So long as there are Preferred Shares Outstanding, the Corporation will enter into futures and options transactions only for bona fide hedging purposes and not for leveraging or speculative purposes. So long as Moody's and S&P are rating the Preferred Shares, the Corporation will only engage in futures or options transactions in accordance with the then-current guidelines of such ratings agencies, only if it is valuing its assets daily and only after it has received written confirmation from Moody's and S&P, as appropriate, that such transactions would not impair the ratings then assigned by S&P and Moody's to Preferred Shares. The S&P guidelines in effect as of the Date of Original Issue are set forth in their entirety in the following paragraph. The Corporation may engage in futures and options transactions in accordance therewith and such transactions shall have the consequences included in such guidelines set forth therein (as such guidelines are amended, modified and supplemented from time to time by S&P), provided, however, that it may not engage in any such transactions unless it has satisfied the relevant provisions of this paragraph relating to complying with Moody's guidelines and obtaining written confirmation from Moody's and S&P.

For so long as Preferred Shares are rated by S&P, the Corporation will not, unless it has received written confirmation from S&P that any such action would not impair the rating then assigned by S&P to Preferred Shares, purchase or sell futures contracts or options thereon or write uncovered put or uncovered call options in portfolio securities except (provided that the Corporation has received such written confirmation in advance from S&P) that (i) the Corporation may engage in S&P Hedging Transactions based on the Municipal Index, provided that (A) the Corporation shall not engage in any S&P Hedging Transaction based on the Municipal Index (other than Closing Transactions) which would cause the Corporation at the time of such transaction to own or have sold (1) more than 1,000 outstanding futures contracts based on the Municipal Index, (2) outstanding futures contracts based on Municipal Index exceeding in number 25% of the quotient of the fair market value of the Corporation's total assets divided by 100,000 or (3) outstanding futures contracts based on the Municipal Index exceeding in number 10% of the average number of daily traded futures contracts based on the Municipal Index in the month prior to the time of effecting such transaction as reported by The Wall Street Journal and (ii) the Corporation may engage in S&P Hedging Transactions based on Treasury Bonds, provided that (A) the Corporation shall not engage in any S&P Hedging Transactions based on Treasury Bonds (other than Closing Transactions) which would cause the Corporation at the time of such transaction to own or have sold the lesser of (1) outstanding futures contracts based on Treasury Bonds exceeding in number 25% of the quotient of the fair market value of the Corporation's total assets divided by 100,000 or (2) outstanding futures contracts based on Treasury Bonds exceeding in number 10% of the average number of daily traded futures contracts based on Treasury Bonds in the month prior to the time of effecting such transaction as reported by The Wall Street Journal. For so long as Preferred Shares are rated by S&P, the Corporation will engage in Closing Transactions to close out any outstanding futures contract which the Corporation owns or has sold or any outstanding option thereon owned by the Corporation in the event (i) the Corporation does not have S&P Eligible Assets with an aggregate Discounted Value equal to or greater than the Preferred Shares Maintenance Amount on two consecutive Valuation Dates and (ii) the Corporation is required to pay Variation Margin on the second such Valuation Date. For so long as Preferred Shares are rated by S&P, the Corporation will engage in a Closing Transaction to close out any outstanding futures contract or option thereon in the month prior to the delivery month under the terms of such futures contract or option thereon unless the Corporation holds securities deliverable under such terms. For purposes of calculating the Discounted Value of S&P Eligible Assets to determine compliance with the Preferred Shares Basic Maintenance Amount, such Discounted Value shall be reduced to an amount equal to (i) 30% of the aggregate settlement value, as marked to market, of any outstanding futures contracts based on the Municipal Index which are owned by the Trust plus (ii) 25% of the aggregate settlement value, as marked to market, of any outstanding futures contracts based on Treasury Bonds which contracts are owned by the Corporation. For so long as Preferred Shares are rated by S&P, when the Corporation writes a futures contract or option thereon, it will maintain an amount of cash, cash equivalents or short-term, fixed-income securities in a segregated account with the Corporation's custodian, so that the amount so segregated plus the amount of Initial Margin and Variation Margin held in the account of the Corporation's broker equals the fair market value of the futures contract, except that in the event the Corporation writes a futures contract or option thereon which requires delivery of an underlying security, the Corporation shall hold such underlying security.

(b) For so long as Preferred Shares are rated by Moody's or S&P, the Corporation will not, unless it has received written confirmation from Moody's and/or S&P, as the case may be, that such action would not impair the ratings then assigned to Preferred Shares by Moody's and/or S&P, as the case may be, (i) borrow money, (ii) engage in short sales of securities, (iii) lend any securities, (iv) issue any class or series of stock ranking prior to or on a parity with the Preferred Shares with respect to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up of the Corporation, (v) reissue any Preferred Shares previously purchased or redeemed by the Corporation, (vi) merge or consolidate into or with any other corporation, (vii) change the Pricing Service or (viii) engage in reverse repurchase agreements.

10. Notice.

Notice shall be deemed given on the earlier of the date received or the date seven days after which such notice is mailed.

The Applicable Percentage will be determined based on (i) the lower of the credit rating or ratings assigned on such date to such shares by Moody's and S&P (or if Moody's or S&P or both shall not make such ratings available, the equivalent of either or both of such ratings by a Substitute Rating Agency or two Substitute Rating Agencies or, in the event that only one such rating shall be available, such rating) and (ii) whether the Corporation has provided notification to the Auction Agent prior to the Auction establishing the Applicable Rate for any dividend pursuant to paragraph 2(f) hereof that net capital gains or other taxable income will be included in such dividend on Preferred Shares as follows:

The Corporation will take all reasonable action necessary to enable Moody's and S&P to provide a rating for the series of Preferred Shares. If either Moody's or S&P shall not make such a rating available, or neither Moody's nor S&P shall make such a rating available, Merrill Lynch, Pierce, Fenner & Smith Incorporated or its affiliates and successors, after consultation with the Corporation, will select a nationally recognized statistical rating organization (a "Substitute Rating Agency") or two nationally recognized statistical rating organizations ("Substitute Rating Agencies") to act as Substitute Rating Agency or Substitute Rating Agencies, as the case may be; provided that if such a rating is not made available with respect to either series of Preferred Shares, Merrill Lynch, Pierce, Fenner & Smith or its affiliates and successors, after consultation with the Corporation, shall select a Substitute Rating Agency or Agencies.

(iii) If an Order or Orders covering all of the Outstanding Preferred Shares held by an Existing Holder is not submitted to the Auction Agent prior to the Submission Deadline, the Auction Agent shall deem a Hold Order to have been submitted on behalf of such Existing Holder covering the number of Outstanding Preferred Shares held by such Existing Holder and not subject to Orders submitted to the Auction Agent; provided, however, that with respect to an Auction to establish a Special Dividend Period longer than 91 days, the Auction Agent shall deem a Sell Order to have been submitted on behalf of such Existing Holder covering such number of Outstanding Preferred Shares.

(A) any Hold Order submitted on behalf of such Existing Holder shall be considered valid up to and including the number of Outstanding Preferred Shares held by such Existing Holder; provided that if more than one Hold Order is submitted on behalf of such Existing Holder and the number of Preferred Shares subject to such Hold Order exceeds the number of Outstanding Preferred Shares held by such Existing Holder, the number of Preferred Shares subject to each of such Hold Orders shall be reduced pro rata so that such Hold Orders, in the aggregate, will cover exactly the number of Outstanding Preferred Shares held by such Existing Holder;

(B) any Bids submitted on behalf of such Existing Holder shall be considered valid, in the ascending order of their respective rates per annum or Spread, if more than one Bid is submitted on behalf of such Existing Holder, up to and including the excess of the number of Outstanding Preferred Shares held by such Existing Holder over the number of Preferred Shares subject to any Hold Order referred to in paragraph 11(c)(iv)(A) above (and if more than one Bid submitted on behalf of such Existing Holder specifies the same rate per annum or Spread and together they cover more than the remaining number of shares that can be the subject of valid Bids after application of paragraph 11(c)(iv)(A) above and of the foregoing portion of this paragraph 11(c)(iv)(B) to any Bid or Bids specifying a lower rate or rates per annum or Spread, the number of shares subject to each of such Bids shall be reduced pro rata so that such Bids, in the aggregate, cover exactly such remaining number of shares); and the number of shares, if any, subject to Bids not valid under this paragraph 11(c)(iv)(B) shall be treated as the subject of a Bid by a Potential Holder; and

(C) any Sell Order shall be considered valid up to and including the excess of the number of Outstanding Preferred Shares held by such Existing Holder over the number of Preferred Shares subject to Hold Orders referred to in paragraph 11(c)(iv)(A) and Bids referred to in paragraph 11(c)(iv)(B); provided that if more than one Sell Order is submitted on behalf of any Existing Holder and the number of Preferred Shares subject to such Sell Orders is greater than such excess, the number of Preferred Shares subject to each of such Sell Orders shall be reduced pro rata so that such Sell Orders, in the aggregate, cover exactly the number of Preferred Shares equal to such excess.

(v) If more than one Bid is submitted on behalf of any Potential Holder, each Bid submitted shall be a separate Bid with the rate per annum or Spread and number of Preferred Shares specified.

(vi) Any Bid by an Existing Holder that specifies a Spread, with respect to an Auction in which a Spread is not included in any Bid Requirements or in which there are no bid Requirements and any Order that does not specify a Spread with respect to an Auction in which a Spread is included in any bid Requirements shall be treated as a Sell Order.

(d) Determination of Sufficient Clearing Bids, Winning Bid Rate and Applicable Rate.

(i) Not earlier than the Submission Deadline on each Auction Date, the Auction Agent shall assemble all Orders submitted or deemed submitted to it by the Broker-Dealers (each such Order as submitted or deemed submitted by a Broker-Dealer being hereinafter referred to individually as a "Submitted Hold Order" a "Submitted Bid" a "Submitted Sell Order", as the case may be, or as a "Submitted Order") and shall determine:

(A) the excess of the total number of Outstanding Preferred Shares over the number of Outstanding Preferred Shares that are the subject of Submitted Hold Orders (such excess being hereinafter referred to as the "Available Preferred Shares");

(B) from the Submitted Orders whether the number of Outstanding Preferred Shares that are the subject of Submitted bids by Potential Holders specifying one or more rates per annum or Spreads that result in one or more rates per annum on such date equal to or lower than the Maximum Applicable Rate in effect for the first Dividend Payment Period after the auction Date exceeds or is equal to the sum of:

(1) the number of outstanding Preferred Shares that are the subject of Submitted Bids by Existing Holders specifying one or more rates per annum or Spreads that result in one or more rates per annum on such date higher than such Maximum Applicable Rate, and

(2) the number of Outstanding Preferred Shares that are subject to Submitted Sell Orders (if such excess or such equality exists (other than because the number of Outstanding Preferred Shares in clauses (1) and (2) above are each zero because all of the Outstanding Preferred Shares are the subject of Submitted Hold Orders), such Submitted Bids by Potential Holders being hereinafter referred to collectively as "Sufficient Clearing Bids"); and

(C) if Sufficient Clearing Bids exist, the lowest rate per annum or, in the case of an, Auction with Bid Requirements including a Spread, the lowest Spread specified in the Submitted Bids (the "Winning Bid Rate") that if:

(1) each Submitted Bid from Existing Holders specifying the Winning Bid Rate and all other Submitted Bids from Existing Holders specifying lower rates per annum or Spreads were rejected, thus entitling such Existing Holders to continue to hold the Preferred Shares that are the subject of such Submitted Bids, and

(2) each Submitted Bid from Potential Holders specifying the Winning Bid Rate and all other Submitted Bids from Potential Holders specifying lower rates per annum or Spreads were accepted, thus entitling the Potential Holders to purchase the Preferred Shares that are the subject of such Submitted Bids, would result in the number of shares subject to all Submitted Bids specifying the Winning Bid Rate or a lower rate per annum or Spread being at least equal to the Available Preferred Shares.

(D) For purposes of these Article Supplementary, a positive Spread shall be considered lower than another positive Spread to the extent it is a lower number, a Spread of Zero shall be considered lower than a positive Spread, a negative Spread shall be considered lower than a Spread of zero and a negative Spread shall be considered lower than another negative Spread to the extent it is a higher number.

(ii) Promptly after the Auction Agent has made the determinations pursuant to paragraph 11(d)(i), the Auction Agent shall advise the Corporation of the Maximum Applicable Rate (or, in the event the Corporation has specified a Maximum Applicable Rate or Rates, or a Minimum Applicable Rate or Rates the Auction Agent shall confirm to the Corporation the calculation of such Maximum Applicable Rate or Rules or such Minimum Applicable Rate or Rates) and based on such determinations, the Applicable Rate for the next succeeding Dividend Period as follows:

(A) if Sufficient Clearing Bids exist, that the Applicable Rate for the next succeeding Dividend Period shall be equal to the Winning Bid Rate, subject to the effect of any applicable Minimum Applicable Rate and any applicable Maximum Applicable Rate;

(B) if Sufficient Clearing Bids do not exist (other than because all of the Outstanding Preferred Shares are the subject of Submitted Hold Orders and other than in the event the Auction is being conducted with respect to a Special Dividend Period), that the Applicable Rate for the next succeeding Dividend Period shall be equal to the Maximum Applicable Rate;

(C) if all of the Outstanding Preferred Shares are the subject of Submitted Hold Orders that the Dividend Period next succeeding the Auction shall automatically be the same length as the immediately preceding Dividend Period and the Applicable Rate for the next succeeding Dividend Period will be the higher of the 30-day "AA" Composite Commercial Paper Rate and the Taxable Equivalent of the Short-Term Municipal Bond Rate multiplied by 1 minus the maximum marginal regular Federal individual income tax rate then applicable to ordinary income or the maximum marginal regular Federal corporate tax rate then applicable, whichever is greater (or 90% of such rate if the Corporation has provided notification to the Auction Agent prior to the Auction establishing the Applicable Rate for any dividend pursuant to paragraph 2(f) hereof that net capital gains or other taxable income will be included in such dividend on Preferred Shares) on the date of the Auction; or

(D) if the Auction is being conducted with respect to a Special Dividend Period and Sufficient Clearing Bids do not exist, that the Dividend Period next succeeding the Auction shall automatically be 28 days (in the case of Series T28 Preferred Shares) or 7 days (in the case of Series T7 Preferred Shares) and the Applicable Rate for the next succeeding Dividend Period will be as set forth in paragraph 11(d)(ii)(C) above.

(e) Acceptance and Rejection of Submitted Bids and Submitted Sell Orders and Allocation of Shares. Based on the determinations made pursuant to paragraph 11(d)(i), the Submitted Bids and Submitted Sell Orders shall be accepted or rejected and the Auction Agent shall take such other action as set forth below:

(i) If Sufficient Clearing Bids have been made, subject to the provisions of paragraph 11(e) (iii) and paragraph 11(e) (iv), Submitted Bids and Submitted Sell Orders shall be accepted or rejected in the following order of priority and all other Submitted Bids shall be rejected:

(A) the Submitted Sell Orders of Existing Holders shall be accepted and the Submitted Bid of each of the Existing Holders specifying any rate per annum or Spread that is higher than the Winning Bid Rate shall be accepted, thus requiring each such Existing Holder to sell the Outstanding Preferred Shares that are the subject of such Submitted Sell Order or Submitted Bid;

(B) the Submitted Bid of each of the Existing Holders specifying any rate per annum or Spread that is lower than the Winning Bid Rate shall be rejected, thus entitling each such Existing Holder to continue to hold the Outstanding Preferred Shares that are the subject of such Submitted Bid;

(C) the Submitted Bid of each of the Potential Holders specifying any rate per annum that is lower than the Winning Bid Rate or Spread shall be accepted;

(D) the Submitted Bid of each of the Existing Holders specifying a rate per annum or Spread that is equal to the Winning Bid Rate shall be rejected, thus entitling each such Existing Holder to continue to hold the Outstanding Preferred Shares that are the subject of such Submitted Bid, unless the number of Outstanding Preferred Shares subject to all such Submitted Bids shall be greater than the number of Outstanding Preferred Shares ("Remaining Shares") equal to the excess of the Available Preferred Shares over the number of Outstanding Preferred Shares subject to Submitted Bids described in paragraph 11(e) (i) (B) and paragraph 11(e) (i)(C), in which event the Submitted Bids of each such Existing Holder shall be accepted, and each such Existing Holder shall be required to sell Outstanding Preferred Shares, but only in an amount equal to the difference between (1) the number of Outstanding Preferred Shares then held by such Existing Holder subject to such Submitted Bid and (2) the number of Preferred Shares obtained by multiplying (x) the number of Remaining Shares by (y) a fraction the numerator of which shall be the number of outstanding Preferred Shares held by such Existing Holder subject to such Submitted bid and the denominator of which shall be the sum of the numbers of Outstanding Preferred Shares subject to such Submitted Bids made by all such Existing Holders that specified a rate per annum equal or Spread to the Winning Bid Rate; and

(E) the Submitted Bid of each of the Potential Holders specifying a rate per annum or Spread that is equal to the Winning Bid Rate shall be accepted but only in an amount equal to the number of Outstanding Preferred Shares obtained by multiplying (x) the difference between the Available Preferred Shares and the number of Outstanding Preferred Shares subject to Submitted Bids described n paragraph 11(e)(i)(B), paragraph 11(e)(i)(C) and paragraph 11(e)(i)(D) by (y) a fraction the numerator of which shall be the number of Outstanding Preferred Shares subject to such Submitted Bid and the denominator of which shall be the sum of the numbers of Outstanding Preferred Shares subject to such Submitted Bids made by all such Potential Holders that specified a rate per annum or Spread equal to the winning Bid Rate.

(ii) If Sufficient Clearing Bids have not been made (other than because all of the Outstanding Preferred Shares are subject to Submitted Hold Orders), subject to the provisions of paragraph 11(e)
(iii), Submitted Orders shall be accepted or rejected as follows in the following order of priority and all other Submitted Bids shall be rejected:

(A) The Submitted Bid of each Existing Holder specifying any rate per annum or Spread that is equal to or lower than the Maximum Applicable Rate (a Bid specifying a Spread being converted to a rate per annum for this purpose by applying the spread to the most recently available Reference Index or Reference Security) shall be rejected, thus entitling such Existing Holder to continue to hold the outstanding Preferred Shares that are the subject of such Submitted Bid;

(B) the Submitted Bid of each Potential Holder specifying any rate per annum or Spread that is equal to or lower than the Maximum Applicable Rate (a Bid specifying a Spread being converted to a rate per annum for this purpose by applying the Spread to the most recently available Reference Index or Reference Security) shall be accepted, thus requiring such Potential Holder to purchase the Outstanding Preferred Shares that are the subject of such Submitted Bid; and

(C) the Submitted Bids of each Existing Holder specifying any rate per annum or spread that is higher than the Maximum Applicable Rate (a Bid specifying a Spread being converted to a rate per annum for this purpose by applying the Spread to the most recently available Reference Index or Reference Security) shall be accepted, and the Submitted Sell Orders of each Existing Holder shall be accepted in both cases only in an amount equal to the difference between (1) the number of Outstanding Preferred Shares then held by such Existing Holder subject to such Submitted Bid or Submitted Sell Order and (2) the number of Preferred Shares obtained by multiplying
(x) the difference between the Available Preferred Shares and the aggregate number of Outstanding Preferred Shares subject to Submitted Bids described in paragraph 11(e)(ii)(A) and paragraph 11(e)(ii)(B) by
(y) a fraction the numerator of which shall be the number of Outstanding Preferred Shares subject to such Submitted Bid or Submitted Sell Order and the denominator of which shall be the number of Outstanding Preferred Shares subject to all such Submitted Bids and Submitted Sell Orders.

(iii) If, as a result of the procedures described in paragraph 11(e)(i) or paragraph 11(e)(ii), any Existing Holder would be entitled or required to sell, or any Potential Holder would be entitled or required to purchase, a fraction of a share of Preferred Shares on any Auction Date, the Auction Agent shall, in such manner as in its sole discretion it shall determine, round up or down the number of Preferred Shares to be purchased or sold by any Existing Holder or Potential Holder on such Auction Date so that each Outstanding share of Preferred Shares purchased or sold by each Existing Holder or Potential Holder on such Auction Date shall be a whole share of Preferred shares.

(iv) If, as a result of the procedures described in paragraph 11(e)(i), any Potential Holder would be entitled or required to purchase less than a whole share of Preferred Shares on any Auction Date, the Auction Agent shall, in such manner as in its sole discretion it shall determine, allocate Preferred Shares for purchase among Potential Holders so that only whole Preferred Shares are purchased on such Auction Date by any Potential Holder, even if such allocation results in one or more of such Potential Holders not purchasing any Preferred Shares on such Auction Date.

(v) Based on the results of each Auction, the Auction Agent shall determine, with respect to each Broker-Dealer that submitted Bids or Sell Orders on behalf of Existing Holders or Potential Holders, the aggregate number of Outstanding Preferred Shares to be purchased and the aggregate number of Outstanding Preferred Shares to be sold by such Potential Holders and Existing Holders and to, the extent that such aggregate number of Outstanding shares to be purchased and such aggregate number of Outstanding shares to be sold differ, the Auction Agent shall determine to which other Broker-Dealer or Broker-Dealers acting for one or more purchasers such Broker-Dealer shall deliver, or from which other Broker-Dealer or Broker-Dealers acting for one or more sellers such Broker-Dealer shall receive, as the case may be, Outstanding Preferred Shares.

(f) Miscellaneous. An Existing Holder (A) may sell, transfer or otherwise dispose of Preferred Shares only pursuant to a Bid or Sell Order in accordance with the procedures described in this paragraph 11 or to or through a broker-dealer, provided that in the case of all transfers other than pursuant to Auctions such Existing Holder, its Broker- Dealer or its Agent Member advises the Auction Agent of such transfer and (B) except as otherwise required by law, shall have the ownership of the Preferred Shares held by it maintained in book entry form by the Securities Depository in the account of its Agent Member, which in turn will maintain records of such Existing Holder's beneficial ownership. Neither the Corporation nor any Affiliate shall submit an Order in any Auction. Any Existing Holder that is an Affiliate shall not sell, transfer or otherwise dispose of Preferred Shares to any Person other than the Corporation. All of the outstanding Preferred Shares of each series shall be represented by a single certificate registered in the name of the nominee of the Securities Depository unless otherwise required by law or unless there is no Securities Depository. If there is no Securities Depository, at the Corporation's option and upon its receipt of such documents as it deems appropriate, any Preferred Shares may be registered in the Stock Register in the name of the Existing Holder thereof and such Existing Holder thereupon will be entitled to receive certificates therefor and required to deliver certificates therefor upon transfer or exchange thereof.

12. Securities Depository; Stock Certificates. (a) If there is a Securities Depository, one certificate for all of the Preferred Shares of each series shall be issued to the Securities Depository and registered in the name of the Securities Depository or its nominee. Additional certificates may be issued as necessary to represent Preferred Shares. All such certificates shall bear a legend to the effect that such certificates are issued subject to the provisions restricting the transfer of Preferred Shares contained in these Articles Supplementary. Unless the Corporation shall have elected, during a Non-Payment Period, to waive this requirement, the Corporation will also issue stop-transfer instructions to the Auction Agent for the Preferred Shares. Except as provided in paragraph (b) below, the Securities Depository or its nominee will be the Holder, and no existing Holder shall receive certificates representing its ownership interest in such shares.

(b) If the Applicable Rate applicable to all Preferred Shares of a series shall be the Non-Payment Period Rate or there is no Securities Depository, the Corporation may at its option issue one or more new certificates with respect to such shares (without the legend referred to in paragraph 12(a)) registered in the names of the Existing Holders or their nominees and rescind the stop-transfer instructions referred to in paragraph 12(a) with respect to such shares.

13. Interpretations. The Board of Directors may interpret the provisions of these Articles Supplementary to resolve any inconsistency or ambiguity, remedy any formal defect or make any other change or modification that does not adversely affect the rights of Existing Holder of Preferred Shares."

SECOND: The amendment to the charter of the Corporation set forth in these Articles of Amendment was advised by the Board of Directors of the Corporation and approved by the stockholders of the Corporation at a special meeting of the stockholders of the Corporation held on July 13, 1994.

THIRD: The amendment to the charter of the Corporation set forth in these Articles of Amendment does not increase the authorized capital stock of the Corporation.

IN WITNESS WHEREOF, the Corporation has caused these Articles of Amendment to be executed by its President and its corporate seal to be affixed hereto and attested to by its Secretary as of the 13th day of July, 1994.

Each officer and director of the Corporation shall be indemnified by the Corporation to the full extent permitted under the General Laws of the State of Maryland, including the advancing of expenses, except that such indemnity shall not protect any such person against any liability to the Corporation or any stockholder thereof to which such person would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office. Absent a court determination that an officer or director seeking indemnification was not liable on the merits or guilty of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office, the decision by the Corporation to indemnify such person must be based upon the reasonable determination of independent counsel or nonparty independent directors, after review of the facts, that such officer or director is not guilty of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office.

The Corporation may purchase insurance on behalf of the officer or director protecting such person to the full extent permitted under the General Laws of the State of Maryland, from liability arising from his activities as officer or director of the Corporation. The Corporation, however, may not purchase insurance on behalf of any officer or director of the Corporation that protects or purports to protect such person from liability to the Corporation or to its stockholders to which such officer or director would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of this office.

You, State Street Bank and Trust Company, will act as Agent for me, and will open an account for me under the Dividend Reinvestment Plan (the "Plan") in the same name as my present shares are registered, and put the Plan into effect for me as of the first record date for a dividend or capital gains distribution after you receive the Authorization duly executed by me.

2. Whenever The BlackRock Investment Quality Municipal Trust Inc. (the "Trust") declares a distribution from capital gains or an income dividend payable in cash you shall use such cash to purchase additional shares of Trust common stock for me in the open market or otherwise. Such purchases will be made on or shortly after the payable date for such dividend or distribution, and in no event more than 45 days after such date except where temporary curtailment or suspension of purchase is necessary to comply with applicable provisions of federal securities law.

3. For all purposes of the Plan:

(a) The market price of the Trust's common stock on a particular date shall be the mean between the highest and lowest sales prices on the New York Stock Exchange on that date, or, if there is no sale on such Exchange on that date, then the mean between the closing bid and asked quotations for such stock on such Exchange on such date.

(b) The net asset value per share of the Trust's common stock on a particular date shall be as determined by or on behalf of the Trust; and

(c) All dividends, distributions and other payment shall be made net of any applicable withholding tax.

4. The open-market purchases provided for above may be made on any securities exchange where the Trust's common stock is traded, in the over-the-counter market or in negotiated transactions and may be on such terms as to price, delivery and otherwise as you shall determine. My funds held by you uninvested will not bear interest, and it is understood that, in any event, you shall have no liability in connection with any inability to purchase shares within 45 days after the initial date of such purchase as herein provided, or with the timing of any purchases effected. You shall have no responsibility as to the value of the common stock of the Trust acquired for my account. For the purposes of cash investments you may commingle my funds with those of other shareholders of the Trust for whom you similarly act as Agent, and the average price (including brokerage commissions) of all shares purchased by you as Agent shall be the price per share allocable to me in connection therewith.

5. You may hold my shares acquired pursuant to my authorization, together with the shares of other shareholders of the Trust acquired pursuant to similar authorizations, in noncertificated form in your name or that of your nominee. You will forward to me any proxy solicitation material and will vote any shares so held for me only in accordance with the proxy returned by me to the Trust. Upon my written request, you will deliver to me, without charge, a certificate or certificates for the full shares.

6. You will confirm to me each acquisition made for my account as soon as practical but not later than 60 days after the date thereof. Although I may from time to time have an undivided fractional interest (computed to three decimal places) in a share of the Trust, no certificates for a fractional share will be issued. However, dividends and distributions on fractional shares will be credited to my account. In the event of termination of my account under the Plan, you will adjust for any such undivided fractional interest in cash at the market value of the Trust's shares at the time of termination less the pro rata expense of any sale required to make such adjustment.

7. Any stock dividends or split shares distributed by the Trust on shares held by you for me will be credited to my account. In the event that the Trust makes available to its shareholders rights to purchase additional shares or other securities, the shares held for me under the Plan will be added to other shares held by me in calculating the number of rights to be issued to me.

8. Your service fee for handling capital gains distributions or income dividends will be paid by the Trust. I will be charged a pro rata share of brokerage commissions on all open- market purchases.

9. I may terminate my account under the Plan by notifying you by telephone or in writing. Such termination will be effective immediately if my notice is received by you not less than ten days prior to any dividend or distribution record date; otherwise such termination will be effective on the first trading day after the payment date for such dividend or distribution with respect to any subsequent dividend or distribution. The Plan may be terminated by you or the Trust upon notice in writing mailed to me at least 90 days prior to any record date for the payment of any dividend or distribution by the Trust. Upon any termination you will cause a certificate or certificates for the full shares held for me under the Plan and cash adjustment for any fraction to be delivered to me without charge. If I elect by notice to you in writing in advance of such termination to have you sell part or all of my shares and remit the proceeds to me, you are authorized to deduct a $2.50 fee plus brokerage commission for this transaction from the proceeds.

10. These terms and conditions may be amended or supplemented by you or the Trust at any time or times but, except when necessary or appropriate to comply with applicable law or the rules or policies of the Securities and Exchange Commission or any other regulatory authority, only by mailing to me appropriate written notice at least 90 days prior to the record date for the first dividend or distribution to which such amendment or supplement applies if by the Trust or if by you 90 days prior to the effective date of such amendment or supplement. The amendment or supplement shall be deemed to be accepted by me unless, prior to the effective date thereof, you receive written notice of the termination of my account under the Plan. Any such amendment may include an appointment by you in your place and stead of a successor Agent under these terms and conditions, with full power and authority to perform all or any of the acts to be performed by the Agent under these terms and conditions. Upon any such appointment of an Agent for the purpose of receiving dividends and distributions, the Trust will be authorized to pay to such successor Agent, for my account, all dividends and distributions payable on common stock of the Trust held in my name or under the Plan for retention or application by such successor Agent as provided in these terms and conditions.

11. You shall at all times act in good faith and agree to use your best efforts within reasonable limits to ensure the accuracy of all services performed under this Agreement and to comply with applicable law, but assume no responsibility, and shall not be liable for loss or damage due to errors unless such error is caused by your negligence, bad faith, or willful misconduct or that of your employees.

12. These terms and conditions shall be governed by the laws of the Commonwealth of Massachusetts.

INVESTMENT ADVISORY AGREEMENT

AGREEMENT, dated February ___, 1993, between The BlackRock Investment Quality Municipal Trust Inc. (the "Trust"), a Maryland corporation, and BlackRock Financial Management L.P. (the "Adviser"), a Delaware limited partnership.

In consideration of the mutual promises and agreements herein contained and other good and valuable consideration, the receipt of which is hereby acknowledged, it is agreed by and between the parties hereto as follows:

1. In General

The Adviser agrees, all as more fully set forth herein, to act as investment adviser to the Trust with respect to the investment of the Trust's assets and to supervise and arrange the purchase of securities for and the sale of securities held in the investment portfolio of the Trust.

2. Duties and obligations of the Adviser with respect to investments of assets of the Trust

(a) Subject to the succeeding provisions of this section and subject to the direction and control of the Trust's Board of Directors, the Adviser shall (i) act as investment adviser for and supervise and manage the investment and reinvestment of the Trust's assets and in connection therewith have complete discretion in purchasing and selling securities and other assets for the Trust and in voting, exercising consents and exercising all other rights appertaining to such securities and other assets on behalf of the Trust; (ii) supervise continuously the investment program of the Trust and the composition of its investment portfolio; and (iii) arrange, subject to the provisions of paragraph 3 hereof, for the purchase and sale of securities and other assets held in the investment portfolio of the Trust.

(b) In the performance of its duties under this Agreement, the Adviser shall at all times conform to, and act in accordance with, any requirements imposed by (i) the provisions of the Investment Company Act of 1940 (the "Act"), and of any rules or regulations in force thereunder; (ii) any other applicable provision of law; (iii) the provisions of the Articles of Incorporation and By-Laws of the Trust, as such documents are amended from time to time; (iv) the investment objective and policies of the Trust as set forth in its Registration Statement on Form N-2; and (v) any policies and determinations of the Board of Directors of the Trust.

(c) The Adviser will bear all costs and expenses of its partners and employees and any overhead incurred in connection with its duties hereunder and shall bear the costs of any salaries or directors fees of any officers or directors of the Trust who are affiliated persons (as defined in the Act) of the Adviser except that the Board of Directors of the Trust may approve reimbursement to the Adviser of the pro rata portion of the salaries, bonuses, health insurance, retirement benefits and all similar employment costs for the time spent on Trust operations (other than the provision of investment advice) of all personnel employed by the Adviser who devote substantial time to Trust operations or the operations of other investment companies advised by the Adviser.

(d) The Adviser shall give the Trust the benefit of its best judgment and effort in rendering services hereunder, but the Adviser shall not be liable for any act or omission or for any loss sustained by the Trust in connection with the matters to which this Agreement relates, except a loss resulting from willful malfeasance, bad faith or gross negligence in the performance of its duties, or by reason of its reckless disregard of its obligations and duties under this Agreement.

(e) Nothing in this Agreement shall prevent the Adviser or any partner, officer, employee or other affiliate thereof from acting as investment adviser for any other person, firm or corporation, or from engaging in any other lawful activity, and shall not in any way limit or restrict the Adviser or any of its partners, officers, employees or agents from buying, selling or trading any securities for its or their own accounts or for the accounts of others for whom it or they may be acting, provided, however that the Adviser will undertake no activities which, in its judgment, will adversely affect the performance of its obligations under this Agreement.

3. Portfolio Transactions and Brokerage

The Adviser is authorized, for the purchase and sale of the Trust's portfolio securities, to employ such securities dealers as may, in the judgment of the Adviser, implement the policy of the Trust to obtain the best net results taking into account such factors as price, including dealer spread, the size, type and difficulty of the transaction involved, the firm's general execution and operational facilities and the firm's risk in positioning the securities involved. Consistent with this policy, the Adviser is authorized to direct the execution of the Trust's portfolio transactions to dealers and brokers furnishing statistical information or research deemed by the Adviser to be useful or valuable to the performance of its investment advisory functions for the Trust.

4. Compensation of the Adviser

(a) The Trust agrees to pay to the Adviser and the Adviser agrees to accept as full compensation for all services rendered by the Adviser as such, a fee computed and payable monthly in an amount equal to .35% of the Trust's average weekly net asset value on an annualized basis. For any period less than a month during which this Agreement is in effect, the fee shall be prorated according to the proportion which such period bears to a full month of 28, 29, 30 or 31 days, as the case may be.

(b) For purposes of this Agreement, the net assets of the Trust shall be calculated pursuant to the procedures adopted by resolutions of the Directors of the Trust for calculating the net asset value of the Trust's shares or delegating such calculations to third parties; provided, however, that the liquidation value of any outstanding preferred stock of the Trust shall not be taken into account in calculating the Trust's average weekly net asset value for purposes of Section 4(a) of this Agreement.

5. Indemnity

(a) The Trust hereby agrees to indemnify the Adviser and each of the Adviser's partners, officers, employees, agents, associates and controlling persons and the partners, officers, employees and agents thereof (including any individual who serves at the Adviser's request as director, officer, partner, trustee or the like of another corporation) (each such person being an "indemnitee") against any liabilities and expenses, including amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and counsel fees (all as provided in accordance with applicable corporate law) reasonably incurred by such indemnitee in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, before any court or administrative or investigative body in which he may be or may have been involved as a party or otherwise or with which he may be or may have been threatened, while acting in any capacity set forth above in this Section 5 or thereafter by reason of his having acted in any such capacity, except with respect to any matter as to which he shall have been adjudicated not to have acted in good faith in the reasonable belief that his action was in the best interest of the Trust and furthermore, in the case of any criminal proceeding, so long as he had no reasonable cause to believe that the conduct was unlawful, provided, however, that (1) no indemnitee shall be indemnified hereunder against any liability to the Trust or its shareholders or any expense of such indemnitee arising by reason of (i) willful malfeasance, (ii) bad faith, (iii) gross negligence or (iv) reckless disregard of the duties involved in the conduct of his position (the conduct referred to in such clauses (i) through (iv) being sometimes referred to herein as "disabling conduct"), (2) as to any matter disposed of by settlement or a compromise payment by such indemnitee, pursuant to a consent decree or otherwise, no indemnification either for said payment or for any other expenses shall be provided unless there has been a determination that such settlement or compromise is in the best interests of the Trust and that such indemnitee appears to have acted in good faith in the reasonable belief that his action was in the best interest of the Trust and did not involve disabling conduct by such indemnitee and (3) with respect to any action, suit or other proceeding voluntarily prosecuted by any indemnitee as plaintiff, indemnification shall be mandatory only if the prosecution of such action , suit or other proceeding by such indemnitee was authorized by a majority of the full Board of the Trust.

(b) The Trust shall make advance payments in connection with the expenses of defending any action with respect to which indemnification might be sought hereunder if the Trust receives a written affirmation of the indemnitee's good faith belief that the standard of conduct necessary for indemnification has been met and a written undertaking to reimburse the Trust unless it is subsequently determined that he is entitled to such indemnification and if the directors of the Trust determine that the facts then known to them would not preclude indemnification. In addition, at least one of the following conditions must be met: (A) the indemnitee shall provide a security for his undertaking, (B) the Trust shall be insured against losses arising by reason of any lawful advances, or (C) a majority of a quorum consisting of directors of the Trust who are neither "interested persons" of the Trust (as defined in Section 2(a) (19) of the Act) nor parties to the proceeding ("Disinterested Non-Party Directors") or an independent legal counsel in a written opinion, shall determine, based on a review of readily available facts (as opposed to a full trial-type inquiry), that there is reason to believe that the indemnitee ultimately will be found entitled to indemnification.

(c) All determinations with respect to indemnification hereunder shall be made (1) by a final decision on the merits by a court or other body before whom the proceeding was brought that such indemnitee is not liable by reason of disabling conduct or, (2) in the absence of such a decision, by (i) a majority vote of a quorum of the Disinterested Non-party Directors of the Trust, or (ii) if such a quorum is not obtainable or even, if obtainable, if a majority vote of such quorum so directs, independent legal counsel in a written opinion. All determinations that advance payments in connection with the expense of defending any proceeding shall be authorized shall be made in accordance with the immediately preceding clause (2) above.

The rights accruing to any indemnitee under these provisions shall not exclude any other right to which he may be lawfully entitled.

6. Duration and Termination

This Agreement shall become effective on the date it is approved by the stockholder of the Trust and shall continue in effect for a period of two years and thereafter from year to year, but only so long as such continuation is specifically approved at least annually in accordance with the requirements of the Act.

This Agreement may be terminated by the Adviser at any time without penalty upon giving the Trust sixty days written notice (which notice may be waived by the Trust) and may be terminated by the Trust at any time without penalty upon giving the Adviser sixty days notice (which notice may be waived by the Adviser), provided that such termination by the Trust shall be directed or approved by the vote of a majority of the Directors of the Trust in office at the time or by the vote of the holders of a "majority" (as defined in the Act) of the voting securities of the Trust at the time outstanding and entitled to vote. This Agreement shall terminate automatically in the event of its assignment (as "assignment" is defined in the Act). The Adviser is a partnership and will notify the Trust promptly after any change in the membership of such partnership.

7. Notices

Any notice under this Agreement shall be in writing to the other party at such address as the other party may designate from time to time for the receipt of such notice and shall be deemed to be received on the earlier of the date actually received or on the fourth day after the postmark if such notice is mailed first class postage prepaid.

8. Governing Law

This Agreement shall be construed in accordance with the laws of the State of New York for contracts to be performed entirely therein without reference to choice of law principles thereof and in accordance with the applicable provisions of the Act.

IN WITNESS WHEREOF, the parties hereto have caused the foregoing instrument to be executed by their duly authorized officers, all as of the day and the year first above written.

WITNESSETH: That in consideration of the mutual covenants and agreements hereinafter contained, the parties hereto agree as follows:

2. The Auction.

2.1 Purpose; Incorporation by Reference of Auction Procedures and Settlement Procedures.

(a) The Articles Supplementary provide that the Applicable Rate on Series T7 Preferred Shares or Series T28 Preferred Shares, as the case may be, for each Dividend Period therefor after the Initial Dividend Period shall be the rate per annum that a commercial bank, trust company, or other financial institution appointed by the Company advises results from implementation of the Auction Procedures. The Board of Directors of the Company has adopted a resolution appointing Bankers Trust Company as Auction Agent for purposes of the Auction Procedures. The Auction Agent hereby accepts such appointment and agrees that, on each Auction Date, it shall follow the procedures set forth in this Section 2 and the Auction Procedures for the purpose of determining the Applicable Rate for the Series T7 Preferred Shares or the Series T28 Preferred Shares, as the case may be, for the next Dividend Period therefor. Each periodic operation of such procedures is hereinafter referred to as an "Auction".

(b) All of the provisions contained in the Auction Procedures and the Settlement Procedures are incorporated herein by reference in their entirety and shall be deemed to be a part hereof to the same extent as if such provisions were fully set forth herein.

2.2 Preparation for Each Auction; Maintenance of Registry of Beneficial Owners.

(a) At the time of closing of the initial issuance and sale of the Preferred Shares (the "Closing"), the Company shall provide the Auction Agent with a list of initial Broker-Dealers previously approved by the Auction Agent and shall cause to be delivered to the Auction Agent for execution by the Auction Agent a Broker-Dealer Agreement signed by each such Broker-Dealer. Subsequent to the Closing and pursuant to
Section 2.5(b) and subject to Section 2.5(c) hereof, the Auction Agent may, from time to time, designate additional Broker Dealers. The Auction Agent shall keep the list of Broker Dealers current and accurate, and shall indicate thereon, or on a separate list, the identity of each Existing Holder, if any, whose most recent Order was submitted by a Broker-Dealer on such list and resulted in such Existing Holder continuing to hold or purchasing Preferred Shares. Not later than seven days prior to any Auction Date for which any change in such list of Broker-Dealers is to be effective, the Auction Agent shall notify the Company in writing of such change and, if any such change is the addition of a Broker-Dealer to such list, the Auction Agent shall have entered into a Broker-Dealer Agreement with such additional Broker-Dealer prior to the participation of any such Broker-Dealer in any Auction.

(b) (i) In the event that the Auction Date for any Auction shall be changed after the Auction Agent shall have given the notice referred to in clause (vii) of Paragraph (a) of the Settlement Procedures, the Auction Agent, by such means as the Auction Agent deems practicable, shall give notice of such change to the Broker-Dealers not later than the earlier of 9:15 A.M. on the new Auction Date or 9:15 A.M. on the old Auction Date.

(ii) If, after the date of this Agreement, there is any change in the prevailing rating of Preferred Shares by either of the rating agencies (or substitute or successor rating agencies) referred to in the definition of the Maximum Applicable Rate, thereby resulting in any change in the corresponding percentage for the Preferred Shares, as set forth in said definition (the "Percentage"), the Company shall notify the Auction Agent in writing of such change in the Percentage prior to 9:00 A.M. on the Auction Date for Preferred Shares next succeeding such change. The Percentage for the Preferred Shares on the date of this Agreement is 110%. The Auction Agent shall be entitled to rely on the last Percentage of which it has received notice from the Company (or, in the absence of such notice, the Percentage set forth in the preceding sentence) in determining the Maximum Applicable Rate as set forth in Section 2.2(e)(i) hereof.

(c) With respect to each Dividend Period that is a Special Dividend Period, on or prior to the fourth day but not more than seven days prior to an Auction Date for each series of the Preferred Shares, the Company may, at its sole option and to the extent permitted by law, by telephonic and written notice (a "Request for Special Dividend Period") to the Auction Agent and to each Broker-Dealer, request that the next succeeding Dividend Period for such series of Preferred Shares will be a number of days (other than 28 in the case of the Series T28 Preferred Shares or 7 in the case of the Series T7 Preferred Shares) evenly divisible by 7 and specified in such notice, provided that for any Auction occurring after the initial Auction, the Company may not give a Request for Special Dividend Period (and any such request shall be null and void) unless sufficient Clearing Bids were made in the last occurring Auction and unless full cumulative dividends, any amounts due with respect to mandatory redemptions and any Additional Dividends payable prior to such date have been paid in full. Such Request for Special Dividend Period, in the case of a Dividend Period of 182 days or less, shall be made on or prior to the 4th day but not more than 7 days prior to an Auction Date for such series of Preferred Shares and, in the case of a Dividend Period of more than 182 days, shall be given on or prior to the 14th day but not more than 28 days prior to an Auction Date for such series of Preferred Shares. Upon receiving such Request for Special Dividend Period, the Broker-Dealer(s) shall jointly determine whether given the factors set forth in paragraph 2(c)(iii) of the Articles Supplementary it is advisable that the Company issue a Notice of Special Dividend Period for the particular series of Preferred Shares as contemplated by such Request for Special Dividend Period and shall give the Company and the Auction Agent written notice (a "Response") of such determination by no later than the third day prior to such Auction Date. If the Broker-Dealer(s) shall not give the Company and the Auction Agent a Response by such third day or if the Response states that given the factors referred to above it is not advisable that the Company give a Notice of Special Dividend Period (as defined below) for the particular series of Preferred Shares, the Company may not give a Notice of Special Dividend Period in respect of such Request for Special Dividend Period. In the event the Response indicates that it is advisable that the Company give a Notice of Special Dividend Period for the particular series of Preferred Shares, the Company will by no later than the second day prior to such Auction Date give a notice (a "Notice of Special Dividend Period") to the Auction Agent, the Securities Depository and each Broker-Dealer, which notice will specify the duration of the Special Dividend Period, the Maximum Applicable Rate therefor and Specific Redemption Provisions, if any. The Company shall not give a Notice of Special Dividend Period or convert to a Special Dividend Period, or, if such Notice of Special Dividend Period shall have already been given, shall give telephonic and written notice of revocation (a "Notice of Revocation") to the Auction Agent, each Broker-Dealer, and the Securities Depository on or prior to the Business Day prior to the relevant Auction Date if (i) it has not obtained the advice in writing of Moody's and S&P or any Substitute Rating Agency that the proposed Special Dividend Period will not adversely affect their then-current rating on the Preferred Shares, (ii) either the 1940 Act Preferred Shares Coverage is not satisfied or the Company shall fail to maintain S&P Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount in each case on each of the two Valuation Dates immediately preceding the Business Day prior to the relevant Auction Date on an actual basis and on a pro forma basis giving effect to the proposed Special Dividend Period (using as a pro forma dividend rate with respect to such Special Dividend Period the dividend rate which the Broker-Dealers shall advise the Company is an approximately equal rate for securities similar to the Preferred Shares with an equal dividend period),
(iii) sufficient funds for the payment of dividends payable on the immediately succeeding Dividend Payment Date have not been irrevocably deposited with the Auction Agent by the close of business on the third Business Day preceding the related Auction Date or (iv) the Broker-Dealer(s) jointly advise the Company that after consideration of the factors referred to above they have concluded that it is advisable to give a Notice of Revocation. If the Company is prohibited from giving a Notice of Special Dividend Period as a result of the factors enumerated in clause
(i), (ii), (iii) or (iv) of the preceding sentence or if the Company gives a Notice of Revocation with respect to a Notice of Special Dividend Period, the next succeeding Dividend Period will be a 28-day Dividend Period in the case of the Series T28 Preferred Shares and a 7-day Dividend Period in the case of the Series T7 Preferred Shares, provided that if the then-current Dividend Period in the case of the Series T28 Preferred Shares is a Special Dividend Period of less than 28 days, the next succeeding Dividend Period will be the same length as the current Dividend Period. In addition, in the event sufficient Clearing Bids are not made in any Auction or an Auction is not held for any reason, the next succeeding Dividend Period will be a 28-day Dividend Period (in the case of Series T28 Preferred Shares) or a 7-day Dividend Period (in the case of Series T7 Preferred Shares) and the Company may not again give a Notice of Special Dividend Period (and any such attempted notice shall be null and void) until sufficient Clearing Bids have been made in an Auction with respect to a 28-day Dividend Period (in the case of Series T28 Preferred Shares) or a 7-day Dividend Period (in the case of Series T7 Preferred Shares).

(d) (i) Whenever the Company intends to include any net capital gains or other taxable income in any dividend on Preferred Shares, the Company will in the case of a Dividend Period of 28 days or fewer, and may, in the case of a Dividend Period of 35 days or more, notify the Auction Agent of the amount to be so included at least five Business Days prior to the Auction Date on which the Applicable Rate for such dividend is to be established. Whenever the Auction Agent receives such notice from the Company, it will in turn notify each Broker Dealer, who, on or prior to such Auction Date, in accordance with its Broker-Dealer Agreement, will notify its Existing Holders and Potential Holders believed to be interested in submitting an Order in the Auction to be held on such Auction Date.

(ii) If the Company makes a Retroactive Taxable Allocation, the Company will, within 90 days (and generally within 60 days) after the end of its fiscal year for which a Retroactive Taxable Allocation is made provide notice thereof to the Auction Agent and to each holder of Preferred Shares (initially the Securities Depository) during such fiscal year at such holder's address as the same appears or last appeared on the stock books of the Company. The Company will, within 30 days after such notice is given to the Auction Agent, pay to the Auction Agent (who will then distribute to such holders of Preferred Shares), a cash amount equal to the aggregate Additional Dividend with respect to all Retroactive Taxable Allocations made to such holders during the fiscal year in question.

(e) (i) On each Auction Date, the Auction Agent shall determine the Maximum Applicable Rate from the higher of the 30-day "AA" Composite Commercial Paper Rate and the Taxable Equivalent of the Short-Term Municipal Bond Rate (except in the case of a Special Dividend Period in which case the Maximum Applicable Rate shall be determined from the higher of the Special Dividend Period Reference Rate and the Taxable Equivalent of the Short-Term Municipal Bond Rate). If any such rate on which the Maximum Applicable Rate is to be based is not quoted on an interest basis but is quoted on a discount basis, the Auction Agent shall convert the quoted rate to an Interest Equivalent, as set forth in Paragraph 1 of the Articles Supplementary; or, if the rate obtained by the Auction Agent is not quoted on an interest or discount basis, the Auction Agent shall convert the quoted rate to an interest rate after consultation with the Company as to the method of such conversion. Not later than 9:30
A.M. on each Auction Date for each series of Preferred Shares, the Auction Agent shall notify the Company and the Broker-Dealers of the applicable rate so determined and the Maximum Applicable Rate.

(ii) If the rate on which the Maximum Applicable Rate is to be based is the 30-day "AA" Composite Commercial Paper Rate and such rate is to be based on rates supplied by Commercial Paper Dealers and one or more of the Commercial Paper Dealers shall not provide a quotation for the determination of the 30-day "AA" Composite Commercial Paper Rate, the Auction Agent shall immediately notify the Company so that the Company can determine whether to select a Substitute Commercial Paper Dealer or Substitute Commercial Paper Dealers to provide the quotation or quotations not being supplied by any Commercial Paper Dealer or Commercial Paper Dealers. The Company shall promptly advise the Auction Agent of any such selection. If the Company does not select any such Substitute Commercial Paper Dealer or Substitute Commercial Paper Dealers, then the rates shall be supplied by the remaining Commercial Paper Dealer or Commercial Paper Dealers.

(f) (i) The Auction Agent shall maintain by series a current registry of the Beneficial Owners of the shares of both series of Preferred Shares for purposes of each Auction. The Company shall use its best efforts to provide or cause to be provided to the Auction Agent within ten days following the date of Closing a list of the initial Beneficial Owners of Series T7 Preferred Shares and Series T28 Preferred Shares and the respective Broker-Dealer of each such Beneficial Owner through which such Beneficial Owner purchased such shares. The Auction Agent may rely upon, as evidence of the identities of the Beneficial Owners, such list, the results of each Auction and notices from any Beneficial Owner, the Agent Member of any Beneficial Owner or the Broker-Dealer of any Beneficial Owner with respect to such Beneficial Owner's transfer of any Preferred Shares to another Person.

(ii) In the event of any partial redemption of any Series T7 Preferred Shares or Series T28 Preferred Shares, as the case may be, upon notice by the Company to the Auction Agent of such partial redemption, the Auction Agent shall promptly request the Securities Depository to notify the Auction Agent of the identities of the Agent Members (and the respective numbers of Preferred Shares) from the accounts of which Preferred Shares have been called for redemption and the person or department at such Agent member to contact regarding such redemption and, at least two Business Days prior to the next Auction with respect to Preferred Shares of the series being partially redeemed, the Auction Agent shall request each Agent Member so identified to disclose to the Auction Agent (upon selection by such Agent Member of the Beneficial owners whose Preferred Shares are to be redeemed) the number of Preferred Shares of such series of Preferred Shares of each such Beneficial Owner, if any, to be redeemed by the Company; provided that the Auction Agent has been furnished with the name and telephone number of a person or department at such Agent member from which it is to request such information. In the absence of receiving any such information with respect to a Beneficial Owner, from such Beneficial Owner's Agent Member or otherwise, the Auction Agent may continue to treat such Beneficial Owner as having beneficial ownership of the number of Series T7 Preferred Shares or Series T28 Preferred Shares shown in the Auction Agent's registry of Beneficial Owners.

(iii) The Auction Agent shall register a transfer of the beneficial ownership of Series T7 Preferred Shares or Series T28 Preferred Shares from a Beneficial Owner to another Beneficial Owner, or other Person if permitted by the Company, and only if (A) such transfer is pursuant to an Auction or (B) if such transfer is made other than pursuant to an Auction, the Auction Agent has been notified in writing in a notice substantially in the form of Exhibit C to the Broker-Dealer Agreement, by such Existing Holder or the Agent Member of such Existing Holder of such transfer. The Auction Agent is not required to accept any notice of transfer delivered for an Auction unless it is received by the Auction Agent by 3:00 P.M. on the Business Day next preceding the applicable Auction Date. The Auction Agent shall rescind a transfer made on the registry of the beneficial owners of any Preferred Shares if the Auction Agent has been notified in writing in a notice substantially in the form of Exhibit D to the Broker-Dealer Agreement by the Agent Member or the Broker-Dealer of any Person that (i) purchased any Preferred Shares and the seller failed to deliver such shares or (ii) sold any Preferred Shares and the purchaser failed to make payment to such Person upon delivery to the purchaser of such shares.

(g) The Auction Agent may request that the Broker-Dealers, as set forth in Section 3.2(c) of the Broker-Dealer Agreements, provide the Auction Agent with a list of their respective customers that such Broker-Dealers believe are Beneficial Owners of shares of either series of Preferred Shares. The Auction Agent shall keep confidential any such information and shall not disclose any such information so provided to any Person other than the relevant Broker-Dealer and the Company provided that the Auction Agent reserves the right to disclose any such information if it is advised by its counsel that its failure to do so would be unlawful.

2.3 Auction Schedule.

The Auction Agent shall conduct Auctions for both series of Preferred Shares in accordance with the schedule set forth below. Such schedule may be changed by the Auction Agent with the consent of the Company, which consent shall not be unreasonably withheld. The Auction Agent shall give notice of any such change to each Broker-Dealer. Such notice shall be received prior to the first Auction Date on which any such change shall be effective.

4.5 Disposition of Cancelled Certificates; Record Retention.

The Paying Agent shall retain stock certificates which have been cancelled in transfer or in exchange and accompanying documentation in accordance with applicable rules and regulations of the Securities and Exchange Commission for two calendar years from the date of such cancellation.

In case of any request or demand for the inspection of the stock register or any other books of the Company in the possession of the Paying Agent, the Paying Agent will notify the Company and secure instructions as to permitting or refusing such inspection. The Paying Agent reserves the right, however, to exhibit the stock register or other records to any person in case it is advised by its counsel that its failure to do so would
(i) be unlawful or (ii) expose it to liability, unless the Company shall have offered indemnification satisfactory to the Paying Agent.

4.7 Return of Funds.

Any funds deposited with the Paying Agent by the Company for any reason under this Agreement, including for the payment of dividends or the redemption of shares of any series of Preferred Shares, that remain with the Paying Agent after 12 months shall be repaid to the Company upon the written request of the Company.

                              as set forth in Section 3.4(a) hereof.

BD shall submit separate Orders to the Auction Agent for each Potential Beneficial Owner or Beneficial Owner on whose behalf BD is submitting an Order and shall not net or aggregate the Orders of Potential Beneficial Owners or Beneficial Owners on whose behalf BD is submitting Orders.

(d) BD shall deliver to the Auction Agent (i) a written notice, substantially in the form attached hereto as Exhibit C, of transfers of Series T7 Preferred Shares or Series T28 Preferred Shares made through BD by a Beneficial Owner to another Person other than pursuant to an Auction, and (ii) a written notice, substantially in the form attached hereto as Exhibit D, of the failure of any Series T7 Preferred Shares or Series T28 Preferred Shares to be transferred to or by any Person that purchased or sold Series T7 Preferred Shares or Series T28 Preferred Shares or through BD pursuant to an Auction. The Auction Agent is not required to accept any notice delivered pursuant to the terms of the foregoing sentence with respect to an Auction unless it is received by the Auction Agent by 3:00 P.M. on the Business Day next preceding the applicable Auction Date.

3.4 Notice of Auction Results.

(a) On each Auction Date, the Auction Agent shall notify BD by telephone as set forth in paragraph (a) of the Settlement Procedures. On the Business Day next succeeding such Auction Date, the Auction Agent shall notify BD in writing of the disposition of all Orders submitted by BD in the Auction held on such Auction Date.

(b) BD shall notify each Beneficial Owner, Potential Beneficial Owner, Existing Holder or Potential Holder on whose behalf BD has submitted an Order as set forth in paragraph (b) of the Settlement Procedures and take such other action as is required of BD pursuant to the Settlement Procedures.

If any Existing Holder selling Preferred Shares in an Auction fails to deliver such shares, the BD of any Person that was to have purchased Series T7 Preferred Shares or Series T28 Preferred Shares in such Auction may deliver to such Person a number of whole shares of such Series T7 Preferred Shares or Series T28 Preferred Shares, as the case may be, that is less than the number of shares that otherwise was to be purchased by such Person. In such event, the number of such Series T7 Preferred Shares or Series T28 Preferred Shares to be so delivered shall be determined by such BD. Delivery of such lesser number of shares shall constitute good delivery. Upon the occurrence of any such failure to deliver shares, such BD shall deliver to the Auction Agent the notice required by Section 3.3(e)(ii) hereof. Notwithstanding the foregoing terms of this Section 3.4(b), any delivery or non-delivery of Series T7 Preferred Shares or Series T28 Preferred Shares which represents any departure from the results of an Auction, as determined by the Auction Agent, shall be of no effect unless and until the Auction Agent shall have been notified of such delivery or non-delivery in accordance with the terms of
Section 3.3(e)(ii) hereof. The Auction Agent shall have no duty or liability with respect to enforcement of this Section 3.4(b).

3.5 Service Charge to Be Paid to BD. On the Business Day next succeeding each Auction Date for each series of Preferred Shares, the Auction Agent shall pay to BD from moneys received from the Company an amount equal to, (a) in the case of any Auction Date immediately preceding any Dividend Period of 28 days or less, the product of (i) a fraction the numerator of which is the number of days in such Dividend Period (calculated by counting the first day of such Dividend Period but excluding the last day thereof) and the denominator of which is 365, times
(ii) 1/4 of 1%, times (iii) $50,000, times (iv) the sum of (A) the aggregate number of shares of such series of Preferred Shares placed by BD in the applicable Auction that were (x) the subject of a Submitted Bid of a Beneficial Owner submitted by BD and continued to be held as a result of such submission and (y) the subject of a Submitted Bid of a Potential Beneficial Owner submitted by BD and were purchased as a result of such submission plus (B) the aggregate number of shares of such series of Preferred Shares subject to valid Hold Orders (determined in accordance with Paragraph 11 of the Articles Supplementary) submitted to the Auction Agent by BD plus (C) the number of shares of such series of Preferred Shares deemed to be subject to Hold Orders by Existing Holders pursuant to Paragraph 11 of the Articles Supplementary that were acquired by such Existing Holders through BD and (b) in the case of any Auction Date immediately preceding any Dividend Period of 35 days or more, that amount as mutually agreed on by the Company and BD, based on a selling concession that would be applicable to an underwriting of fixed or variable rate preferred shares with a similar final maturity or variable rate dividend period, respectively, at the commencement of the Dividend Period with respect to such Auction. For the purposes of calculating any such fee, Preferred Shares will be placed by a Broker-Dealer if such shares were
(i) the subject of Hold Orders deemed to have been made by Existing Holders that were acquired by such Existing Holders through such Broker-Dealer or
(ii) the subject of the following Orders submitted by such Broker-Dealer:
(A) a Submitted Bid of an Existing Holder that resulted in such Existing Holder continuing to hold such shares as a result of the Auction, (B) a Submitted Bid of a Potential Holder that resulted in such Potential Holder purchasing such shares as a result of the Auction or (C) a Submitted Hold Order.

For purposes of subclause (iv) (C) of the foregoing sentence, if any Existing Holder who acquired Series T7 Preferred Shares or Series T28 Preferred Shares through BD transfers those shares to another Person other than pursuant to an Auction, then the Broker-Dealer for the shares so transferred shall continue to be BD, provided, however, that if the transfer was effected by, or if the transferee is, a Broker-Dealer other than BD, then such Broker-Dealer shall be the Broker-Dealer for such shares.

3.6 Settlement.

(a) If any Beneficial Owner with respect to whom BD has submitted a Bid or Sell Order for Series T7 Preferred Shares or Series T28 Preferred Shares that was accepted in whole or in part fails to instruct its Agent Member to deliver the Preferred Shares subject to such Bid or Sell Order against payment therefor, BD shall instruct such Agent Member to deliver such Preferred Shares against payment therefor and BD may deliver to the Potential Holder or Potential Beneficial Owner with respect to whom BD submitted a Bid for Preferred Shares of such series that was accepted in whole or in part a number of Preferred Shares of such series that is less than the number of Preferred Shares of such series specified in such Bid to be purchased by such Potential Holder or Potential Beneficial Owner. Notwithstanding the foregoing terms of this Section, any delivery or non-delivery of Preferred Shares of either series which represents any departure from the results of an Auction for such series, as determined by the Auction Agent, shall be of no effect unless and until the Auction Agent shall have been notified of such delivery or non-delivery in accordance with the terms of Section 3.3(d) hereof. The Auction Agent shall have no duty or liability with respect to enforcement of this Section 3.6.

(b) Neither the Auction Agent nor the Company shall have any responsibility or liability with respect to the failure of an Existing Holder, a Potential Holder, a Beneficial Owner, a Potential Beneficial Owner or its respective Agent Member to deliver either series of Preferred Shares or to pay for Series T7 Preferred Shares or Series T28 Preferred Shares sold or purchased pursuant to the Auction Procedures or otherwise.

Securities certificate shall bear the following legend:

Unless this certificate is presented by an authorized representative of The Depositor Trust Company, a New York corporation, "DTC," to Issuer or its agent for registration of transfer exchange, or payment, and any certificate issued is registered in the name of Cede & Co. or in such other name as is requested by an authorized representative of DTC and any payment as made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest herein.

2. In the event of any solicitation of consents from or voting by holders of the Securities, Issuer shall establish a record date for such purposes (with no provision for revocation of consents or votes by subsequent holders) and shall, to the extent possible, send notice of such record date to DTC not less than 15 Calendar days in advance of such record date.

Manager: Announcements
Dividend Department
The Depository Trust Company 7 Hanover Square, 23rd Floor New York, NY 10004-2695

7. The Document indicates that each purchaser of Securities must sign a purchaser's letter which contains provisions restricting transfer of the Securities purchased. Issuer and Trust Company acknowledge that as long as Cede & Co is the sole record owner of the Securities, Cede & Co. shall be entitled to all voting rights applicable to the Securities and to receive the full amount of dividends, liquidation proceeds, and redemption proceeds payable with respect to the Security even if the credits of Securities to the DTC accounts of any DTC Participant ("Participant") result from transfers or failures to transfer in violation of the provisions of the purchaser's letter. Issuer and Trust Company acknowledge that DTC shall treat any Participant having Securities credited to its DTC accounts as entitled to the full benefits of ownership of such Securities. Without limiting ____ generality of the preceding sentence. Issuer and Trust Company acknowledge that DTC shall treat any Participant having Securities credited to its DTC accounts as entitled to receive dividend distributions, and voting rights, if any, in respect of Securities and, subject to Paragraphs 11 and 12 to receive certificates evidencing Securities if such certificates are to be issued in accordance with Issuer's certificate of incorporation. The treatment by DTC of the effects of the crediting by it of Securities to the accounts of Participants described in the preceding two sentences shall not affect the rights of Issuer, participants in auctions relating to the Securities, purchasers, sellers or holders of Securities against any Participant. DTC shall not have any responsibility to ascertain whether any transfer of Securities is made in accordance with the provisions of the purchaser's letter.

8. Transactions in the Securities shall be eligible for same-day funds settlement in DTC Same- Day Funds Settlement ("SDFS") system:

A. Dividend payments shall be received by Cede & Co., as nominee of DTC, or its registered assigns in same-day funds on each payment date (or the equivalent in accordance with existing arrangements between Issuer or Trust Company and DTC). Such payments are to be made payable to the order of Cede & Co. Absent any other existing arrangements such payments shall be addressed as follows:

Manager: Cash Receipts Dividend Department The Depository Trust Company 7 Hanover Square, 24th Floor New York, NY 10004-2695

B. Redemption payments shall be made in same-day funds by Trust Company in the manner set forth in the SDFS Paying Agent Operating Procedures, a copy of which previously has been furnished to Trust Company.

9. DTC may direct Issuer or Trust Company to use any other number or address as the number or address to which notices, payments of dividends, or redemption proceeds may be sent.

10. In the event of a redemption necessitating a reduction in the number of Securities outstanding, DTC, in its discretion: (a) may request Issuer or Trust Company to issue and authenticate a new Security certificate; or (b) may make an appropriate notation on the Security certificate indicating the date and amount of such reduction in the number of Security outstanding, except in the case of final redemption, in which case the certificate will be presented to Issuer or Trust Company prior to payment, if required.

11. In the event that Issuer determines that beneficial owners of Securities shall be able to obtain certificated Securities, Issuer or Trust Company shall notify DTC of the availability of certificates. In such event, Issuer or Trust Company shall issue, transfer, and exchange certificate in appropriate amounts, as required by DTC and others.

12. DTC may discontinue providing its services as securities depository with respect to the Securities at any time by giving reasonable notice to Issuer or Trust Company (at which time DTC will confirm with Issuer or Trust Company the aggregate principal amount of Securities outstanding). Under such circumstances, at DTC's request Issuer and Trust Company shall cooperate fully with DTC by taking appropriate action to make available one or more separate certificates evidencing Securities to any DTC Participant having Securities credited to its DTC accounts.

13. Issuer hereby authorizes DTC to provide to Trust Company security position listings of Participants with respect to the Securities from time to time at the request of Trust Company. Issuer also authorizes DTC, in the event of a partial redemption of Securities, to provide Trust Company, upon request, with the names of those Participants whose positions in Securities have been selected for redemption by DTC. DTC will use its best efforts to notify Trust Company of those Participants whose positions in Securities have been selected for redemption by DTC. Issuer authorizes and instructs Trust Company to provide DTC with such signatures, examples of signatures, and authorizations to act as may be deemed necessary or appropriate by DTC to permit DTC to discharge its obligations to its Participants and appropriate regulatory authorities. Such requests for security position listing shall be sent to DTC's Reorganization Department in a manner set forth in Paragraph 4.

This authorization, unless revoked by Issuer, shall continue with respect to the Securities while any Securities are on deposit at DTC, until and unless Trust Company shall no longer be acting. In such event, Issuer shall provide DTC with similar evidence, satisfactory to DTC, of the authorization of any successor thereto so to act..

14. Issuer: (a) understands that DTC has no obligation to, and will not, communicate to Participants or to any person having an interest in the Securities any information contained in Security Certificate(s); and
(b) acknowledges that neither DTC's Participants nor any person having an interest in the Securities shall be deemed to have notice of the provisions of the Security certificate(s) by virtue of submission of submission of such certificates to DTC.

15. Nothing herein shall be deemed to require Trust Company to advance funds on behalf of Issuer.

Notes:

A. If there is a Trust Company (as defined in this Letter of Representations), Trust Company as well as Issuer must sign this Letter. If there is no Trust Company, in signing this Letter Issuer itself undertakes to perform all of the obligations set forth herein.

B. Schedule A contains statements that DTC believes accurately describe DTC, the method of effecting book-entry transfers of securities distributed through DTC and certain related matters.

SCHEDULE A

SAMPLE OFFERING DOCUMENT LANGUAGE
DESCRIBING BOOK-ENTRY-ONLY ISSUANCE

(Prepared by DTC bracketed material may be applicable only to certain issues.)

1. The Depository Trust Company ("DTC") New York, NY, will act as securities depository for the securities ("Securities"). The Securities will be issued as fully-registered in the name of Cede & Co. (DTC's partnership nominee). One fully-registered Security certificate will be issued for [each issue of] the Securities [each] the aggregate principal amount of such issue, and will deposited with DTC. [If, however, the aggregate principal amount of [any] issue exceeds $150 million, one certificate will be issued with respect to each $150 million of principal amount and an additional certificate will be issued with respect to any remaining principal amount os such issue.

2. DTC is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "cleaning agency" registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC holds securities that it's participants ("Participants") deposit with DTC. DTC also facilitates the settlement among Participants of securities transactions such as transfers and pledges, in deposited securities through electronic computerized book- entry changes in Participants' accounts, thereby eliminating the need for physical movement of securities certificates. Direct Participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is owned by a number of its Direct Participants and by the New York Stock Exchange, Inc., American Stock Exchange, Inc., and the National Association of Securities Dealers, Inc. Access to the DTC system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly ("Indirect Participants") applicable to DTC and its Participants are on file with the Securities and Exchange Commission.

3. Purchasers of Securities under the DTC system must be made by or through Direct Participants, which receive a credit for the Securities of DTC's records. The ownership interest of each actual purchaser of each ("Beneficial Owner") is in turn to be recorded on the Direct and Indirect Participants' records. Beneficial Owners will not receive written confirmation from DTC of their purchase, but Beneficial Owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership in the Securities are to be accomplished by entries made on the books of the Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in Securities in the event that use of the book-entry system for the Securities is discontinued.

4. To facilitate subsequent transfers, all Securities deposited by Participants with DTC are registered in the name of DTC's partnership nominee, Cede & Co. The deposit of Securities with DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners Securities; DTC's records reflect only the identity of the Direct Participants to whose accounts such Securities are credited, which may or may not be the Beneficial Owners. The Participants will remain responsible for keeping account of their holdings on behalf of their customers.

5. Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

[6. Redemption notices shall be sent to Cede & Co. If less than all of the Securities within an issue are being redeemed, DTC's practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.]

7. Neither DTC nor Cede & Co. will consent or vote with respect to Securities. Under its usual procedures, DTC mails an Omnibus Proxy to the Issuer as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those Direct Participants to whose accounts the Securities are credited on the record date (identified in a listing attached to the Omnibus Proxy).

8. Principal and interest payments on the Securities will be made to DTC. DTC's practice is to credit Direct Participants' accounts on payable date in accordance with their respective holdings shown on DTC's records unless DTC has reason to believe that it will not receive payment on payable date. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices as is the case with securities held for the accounts of customers in bearer form or registered in "street name" and will be the responsibility of such Participant and not of DTC the Agent of the Issuer subject to any statutory or regulatory requirements as may be in effect from time to time Payment of principal and interest to DTC and disbursement of such payments to the Beneficial Owners shall be the responsibility of Direct and Indirect Participants.

[9. A Beneficial Owner shall give notice to elect to have its Securities purchased or tendered through its Participant, to the
[Tender/Remarketing] Agent, and shall effect delivery of such Securities by causing the Direct Participant to transfer the Participant's interest in the Securities, on DTC's records, to the [Tender/Remarketing] Agent. The requirement for physical delivery of Securities in connection with a demand for purchase or a mandatory purchase will be deemed satisfied when the ownership rights in the Securities are transferred by Direct Participants on DTC's records.]

10. DTC may discontinue providing its services as securities depository with respect to the Securities at any time by giving reasonable notice to the Issuer or the Agent. Under such circumstances, in the event that a successor securities depository is not obtained, Security certificates are required to be printed and delivered.

11. The Issuer may decide to discontinue use of the system of book- entry transfers through DTC (or a securities depository). In that event, Security certificates will be printed and delivered.

12. The information in this section concerning DTC and DTC's book- entry system has been obtained from sources that the Issuer believes to be reliable, but the Issuer takes no responsibility for the accuracy thereof.
