PROSPECTUS

                                  $26,550,000

                            The BlackRock California
                     Insured Municipal 2008 Term Trust Inc.

                            1,062 Shares, Series W7
                    Liquidation Preference $25,000 Per Share

  The BlackRock California Insured Municipal 2008 Term Trust Inc. is a closed-
end, non-diversified management investment company.

  The Trust's investment objective is:

  . to provide current income that is exempt from regular Federal and
    California income tax; and

  . to return $15 per common share (the initial public offering price per
    common share) to holders of common shares on or about December 31, 2008.

 The Trust seeks to achieve its investment objective by investing at least 80%
of its total assets in a non-diversified portfolio of California municipal
obligations insured as to the timely payment of both principal and interest by
insurers with claims-paying abilities rated at the time of investment Aaa by
Moody's Investors Service, Inc. or AAA by Standard & Poor's Rating Services or
which are determined by the Trust's investment advisor to have equivalent
claims-paying abilities. The Trust may invest up to 20% of its total assets in
uninsured California municipal obligations which are:

  . rated at the time of investment Aaa by Moody's or AAA by S&P;

  . guaranteed by an entity with a Aaa or AAA rating;

  . backed by an escrow or trust account containing sufficient U.S. Government
    or U.S. Government agency securities to ensure timely payment of principal
    and interest; or

  . determined by the Trust's investment advisor to be of Aaa or AAA credit
    quality at the time of investment.

 The Trust seeks to return $15 per common share to common shareholders on or
about December 31, 2008 (when the Trust will terminate) by actively managing
its portfolio of California municipal obligations which will have an average
final maturity on or about such date and by retaining each year a small portion
of its net investment income, which portion will not exceed 10% for any year,
as determined in accordance with the Federal income tax rules applicable to the
Trust. No assurance can be given that the Trust will achieve its investment
objective. BlackRock Advisors, Inc. acts as the investment advisor to the
Trust. The address of the Trust is 800 Scudders Mill Road, Plainsboro, New
Jersey 08536 and its telephone number is (800) 688-0928.

 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-

may not provide you with liquidity.

   The Trust is offering 1,062 newly issued shares of Auction Rate Municipal
Preferred Stock, Series W7. 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 W7 Preferred Shares (together with the Trust's
outstanding Series W28 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 the initial dividend 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 "W7"
means that the auction for the New Preferred Shares normally will be held every
Wednesday 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:

  . 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;

  . auctions will be conducted by telephone; and

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

   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
and California 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. Investment in the New Preferred Shares may not be as appropriate
for corporations subject to California franchise tax or California corporate
income 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 will, in the case
of a dividend period of 28 days or less, and may in the case of a dividend
period of 35 days or more, give notice of the amount of any income subject to
regular Federal or California 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 or California 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 Trust intends to redeem
all of the New Preferred Shares and all of its other Preferred Shares no later
than the last dividend payment date in respect of each series prior to December
31, 2008 (when the Trust will terminate).

   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.

                          $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 W7
                          preferred shares. The Trust intends to redeem all of
                          its Preferred Shares (including the New Preferred
                          Shares) no later than the last dividend payment date
                          prior to December 31, 2008 (when the Trust will
                          terminate).

                          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
                          current income exempt from regular Federal and
                          California income tax and to return $15 per common
                          share (the initial offering price per common share)
                          to holders of common shares on or about December 31,
                          2008. No assurance can be given that the Trust will
                          achieve its investment objective.

                          The Trust seeks to achieve its investment objective
                          by investing at least 80% of its total assets in a
                          non-diversified portfolio of California municipal
                          obligations insured as to the timely payment of both
                          principal and interest by insurers with claims-paying
                          abilities rated at the time of investment Aaa by
                          Moody's or AAA by S&P or which are determined by the
                          Trust's investment advisor to have equivalent claims-
                          paying abilities. The Trust may invest up to 20% of
                          its total assets in uninsured California municipal
                          obligations which are:

                          . rated at the time of investment Aaa by Moody's or
                            AAA by S&P;

                          . guaranteed by an entity with an Aaa or AAA rating;

                          . backed by an escrow or trust account containing
                            sufficient U.S. Government or U.S. Government
                            agency securities to ensure timely payment of
                            principal and interest; or

                          . determined by the Trust's investment advisor to be
                            of Aaa or AAA credit quality at the time of
                            investment.

                          The Trust seeks to return $15 per common share to
                          holders of common shares on or about December 31,
                          2008 (when the Trust will terminate) by actively
                          managing its portfolio of tax-exempt California
                          municipal obligations which will have an average
                          final maturity on or about such date and by retaining
                          each year a small portion of its net investment
                          income, which portion will not exceed 10% for any
                          year as determined in accordance with the Federal
                          income tax rules applicable to the Trust.

Investment Advisor......  BlackRock Advisors, Inc. (the "Advisor") acts as the
                          Trust's investment advisor. The investment advisor is
                          responsible for the investment strategy of the Trust.
                          The investment advisor and its affiliates comprise a
                          global asset management firm with assets of
                          approximately $165 billion under management as of
                          December 31, 1999.

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

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

                          . 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;

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

                          . the Trust may be forced to redeem your shares to
                            meet regulatory or rating agency requirements or
                            may voluntarily redeem your shares;

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

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

                          . 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;

                          . because the Trust invests primarily in a portfolio
                            of California municipal obligations, the Trust is
                            more susceptible to political, economic, regulatory
                            or other factors affecting issuers of California
                            municipal obligations than a fund that does not
                            invest primarily in the obligations of such
                            issuers; and

                          . because the Trust is classified as a "non-
                            diversified" fund and may therefore invest a
                            greater portion of its assets in a more limited
                            number of issuers than a "diversified" fund, the
                            Trust may be subject to

                                       5
<PAGE>

                           greater risk than a diversified fund because changes
                           in the financial condition or market assessment of a
                           single issuer may cause greater fluctuation in the
                           net asset value of the Trust.

Secondary Market          The New Preferred Shares will not be listed on a
Trading.................  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 Thursday,
                          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 California
                          municipal obligations that pay interest that is
                          exempt from regular Federal and California income
                          tax, the income you receive will ordinarily be exempt
                          from regular Federal and California income tax. All
                          or a portion of the income from these bonds may be
                          subject to the Federal alternative minimum tax, so
                          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. Investment in the New Preferred Shares may
                          not be appropriate for corporations subject to
                          California franchise tax or California corporate
                          income tax. 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

                                       6
<PAGE>

                          may be subject to income tax on income or gains
                          attributed to the Trust. The Trust will, in the case
                          of a dividend period of 28 days or less, and may, in
                          the case of a dividend period of 35 days or more,
                          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.....................  All or a portion of the Trust's dividends may be
                          subject to the Federal alternative minimum tax.

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 their issuance that the New
                          Preferred Shares 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 rating assigned
                          to 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 California Insured Municipal 2008 Term Trust Inc. (the
"Trust") is a non-diversified, closed-end management investment company. The
Trust was incorporated under the laws of the State of Maryland on August 7,
1992, and has registered under the Investment Company Act of 1940 (the "1940
Act"). The Trust will distribute substantially all of its net assets on or
about December 31, 2008, when the Trust will terminate. 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 September 28, 1992 upon the
closing of the initial public offering of 9,500,000 of its common shares. The
net proceeds of such offering were approximately $133.9 million. In November
1992, the Trust, pursuant to an over-allotment option granted to the
underwriters in the initial public offering, sold an additional 900,000 of its
common shares for net proceeds of approximately $12.7 million.

   On November 16, 1992, the Trust issued 780 preferred shares of stock,
designated Series W7 and 780 preferred shares of stock, designated Series W28.
The preferred shares were 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 occurred on
July 24, 1995.

   As of December 31, 1999, 10,407,093 common shares, 1,560 Preferred Shares,
Series W7 and 1,560 Preferred Shares, Series W28 were outstanding. The Trust's
common shares are traded on the New York Stock Exchange under the symbol "BFC."

   The net proceeds of the offerings will be $25,984,500, 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 California municipal obligations that meet those 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 and California income tax.

                       INVESTMENT OBJECTIVE AND POLICIES

   The Trust's investment objective is to provide current income exempt from
regular Federal and California income tax and to return $15 per common share to
holders of common shares on or about December 31, 2008. No assurance can be
given that the Trust will achieve its investment objective.

   The Trust seeks to achieve its investment objective by investing at least
80% of its total assets in a portfolio of California municipal obligations
insured as to the timely payment of both principal and interest by insurers
with claims-paying abilities rated at the time of investment Aaa by Moody's or
AAA by S&P or which are determined by BlackRock Advisors, Inc. (the "Advisor")
to have equivalent claims-paying abilities. The Trust may invest up to 20% of
its total assets in uninsured California municipal obligations which are:

  . rated at the time of investment Aaa by Moody's or AAA by S&P;

  . guaranteed by an entity with a Aaa or AAA rating;

  . backed by an escrow or trust account containing sufficient U.S.
    Government or U.S. Government agency securities to ensure timely payment
    of principal and interest; or

  . determined by the Advisor to be of Aaa or AAA credit quality at the time
    of investment.

   Generally, California municipal obligations which are covered by insurance
or a guarantee would not be rated Aaa or AAA, and might not be considered to be
of investment grade credit quality in the absence of such insurance or
guarantee. In determining whether to purchase a particular California municipal
obligation which is covered by insurance or a guarantee, the Advisor considers
the credit quality of the underlying issuer (among other factors such as price,
yield and maturity), although such credit quality will not necessarily be the
determinative factor in making the investment decision.

   California municipal obligations which are backed by an escrow or trust
account which contains U.S. Government or U.S. Government agency securities
("collateralized obligations") generally are not insured and may not be rated
Aaa by Moody's or AAA by S&P, and may not be of equivalent credit quality in
the view of the Advisor. Collateralized obligations include, but are not
limited to, California municipal obligations that have been (i) advance
refunded where the proceeds of the funding have been used to purchase U.S.
Government or U.S. Government agency securities that are placed in escrow and
whose interest or maturity principal payments, or both, are sufficient to cover
the remaining scheduled debt service on the California municipal obligations,
or (ii) issued under state and local housing finance programs which use the
issuance proceeds to fund mortgages that are then exchanged for U.S. Government
or U.S. Government agency securities and deposited with a trustee as security
for the California municipal obligations. These collateralized obligations are
normally regarded as having the credit characteristics of the underlying U.S.
Government or U.S. Government agency securities.

   The Trust seeks to return $15 per common share to holders of common shares
on or about December 31, 2008 (when the Trust will terminate) by actively
managing its portfolio of tax-exempt California municipal obligations, which
will have an average final maturity on or about such date and by retaining each
year a small portion of its net investment income, which portion will not
exceed 10% for any year as determined in accordance with the Federal income tax
rules applicable to the Trust. The purpose of retaining a small portion of net
investment income is to enhance the Trust's ability to return to investors $15
per common share outstanding upon the Trust's termination. Such retained income
will serve to increase the net asset value of the Trust and a portion of such
retained income will be available to offset capital losses, if any. However, if
the Trust realizes any capital losses on dispositions of securities that are
not offset by capital gains on the disposition of other securities or the
retention of net investment income, the Trust may return less than $15 for each
common share outstanding at the end of the Trust's term. In addition, the
leverage caused by the Trust's issuance of preferred stock may increase the
possibility of incurring capital losses and the difficulty of subsequently
incurring capital gains to offset such losses. However, the Advisor believes
that it will be able to manage the Trust's assets so that the Trust will not
realize capital losses which are not offset by capital gains

                                       12
<PAGE>

over the life of the Trust on the disposition of its other assets and retained
net investment income. Although neither the Advisor nor the Trust can guarantee
these results, their achievement should enable the Trust, on or about December
31, 2008, to have available for distribution to holders of its common shares
$15 for each common share then outstanding.

   Moody's highest rating category is Aaa. S&P's highest rating category is
AAA. The process of determining ratings for California municipal obligations by
Moody's and S&P includes consideration of the likelihood of the receipt by
securityholders of all distributions, the nature of the underlying securities,
the credit quality of the guarantor, if any, and the structural, legal and tax
aspects associated with such securities. Publications of Moody's indicate that
it assigns a Aaa rating to securities that "are judged to be of the best
quality" and "carry the smallest degree of investment risk." Publications of
S&P indicate that it assigns a AAA rating to securities for which the obligor's
"capacity to meet its financial commitment on the obligation is extremely
strong."

   In normal circumstances, the Trust disposes of insured California municipal
obligations in its portfolio if the claims-paying ability of their insurer
declines below Aaa in the case of Moody's or AAA in the case of S&P, unless the
Trust obtains appropriate alternate insurance covering such California
municipal obligations. The Trust may deviate from the foregoing policy relating
to the disposal of California municipal obligations when, in the Advisor's
judgment, appropriate alternative insurance is not available or is unduly
costly or if the Advisor believes that an insurer whose claims-paying ability
rating has been lowered is taking steps which will cause its rating to be
restored promptly to the Aaa or AAA level. Similarly, the Trust intends to
dispose of uninsured California municipal obligations rated Aaa or AAA or
guaranteed by an entity with such a rating if their credit quality (or that of
their guarantor) declines below Aaa or AAA, or, if they are not rated, the
Advisor no longer believes them to be of triple-A credit quality.

   All or a portion of the Trust's dividends paid in respect of its common
shares, its outstanding preferred shares and the New Preferred Shares may be
subject to Federal alternative minimum tax. See "California Municipal
Obligations."

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

   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 for purposes of enhancing
liquidity and/or preserving capital. The Trust may also invest in California
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 Preferred
Shares, including the New Preferred Shares, will be more likely to approximate
or exceed the net rate of return on the Trust's investment portfolio, with the
consequence that the leverage resulting from the New Preferred Shares may
become less beneficial or adverse to the holders of common shares.

                        CALIFORNIA MUNICIPAL OBLIGATIONS

   California municipal obligations include debt obligations issued by or on
behalf of the State of California, its political subdivisions, agencies and
instrumentalities, and by other qualifying issuers that pay interest which, in
the opinion of the bond counsel to the issuer, is exempt from regular Federal
and California income tax.

                                       13
<PAGE>

California municipal obligations may be issued to obtain funds for various
public purposes, including 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 California
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 California 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 the Federal alternative minimum tax; and (ii)
qualified "private activity" obligations (typically industrial revenue bonds)
that generate income that is tax-exempt under regular Federal income tax rules
and the rules governing California taxes but must, if issued after August 7,
1986, be included in computing the Federal alternative minimum tax. The Trust
will not invest in California municipal obligations that generate interest that
by its terms is subject to Federal income tax other than the Federal
alternative minimum tax.

   The types of California 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 yields on California 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 and S&P represent their opinions as to the quality of those
California municipal obligations that they rate.

   It should be emphasized that ratings are general and are not absolute
standards of quality. Consequently, California 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 California 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 California 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 California municipal obligations available in the market
were subject to call provisions. When California municipal obligations are
called by their issuers, the Advisor reinvests the proceeds from the called
securities in other California municipal obligations. Because the Trust has a
limited term, the Advisor reinvests the proceeds in California municipal
obligations maturing prior to the expiration of the term. As the Trust
approaches its termination date on December 31, 2008, the Advisor will be
required to reinvest in shorter term municipal obligations with relatively
lower interest rates.

   Obligations of issuers of California 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.

                                   INSURANCE

   The Trust generally invests at least 80% of its total assets in a portfolio
of California municipal obligations insured as to the timely payment of both
principal and interest by insurers with claims-paying abilities rated Aaa by
Moody's or AAA by S&P at the time of investment or, if not rated, which are
determined by the

                                       14
<PAGE>

Advisor to have equivalent claims-paying abilities. See Appendix B to the
statement of additional information for a brief description of Moody's and
S&P's insurance claims-paying ability ratings.

   Certain insurance companies will issue policies guaranteeing the timely
payment of principal of, and interest on, particular California municipal
obligations or on a portfolio of California municipal obligations. Insurance
may be purchased by the issuer of a California municipal obligation or by a
third party at the time of issuance of the California municipal obligation
("Original Issue Insurance") or by the Trust or a third party subsequent to the
original issuance of a California municipal obligation ("Secondary Insurance").
In each case, a single premium is paid to the insurer by the party purchasing
the insurance when the insurance is obtained. Original Issue Insurance and
Secondary Insurance policies are non-cancellable and remain in effect for so
long as the insured California municipal obligation is outstanding and the
insurer is in business. Accordingly, whether a particular California municipal
obligation is covered by Original Issue Insurance as opposed to Secondary
Insurance will not, in and of itself, be determinative to the Trust in making
an investment decision to purchase such California municipal obligation.

   The Trust may also purchase insurance covering certain California municipal
obligations which it intends to purchase for its portfolio or which it already
owns ("Portfolio Insurance"). Portfolio Insurance policies guarantee the timely
payment of principal of, and interest on, covered California municipal
obligations only while they are owned by the Trust. Such policies are non-
cancellable and remain in effect until the Trust terminates provided the Trust
pays the applicable insurance premiums and the insurer remains in business.
California municipal obligations in the Trust's portfolio covered by a
Portfolio Insurance policy will not be covered by such policies after they are
sold by the Trust unless the Trust elects to obtain some form of Secondary
Insurance for them at the time of sale. The Trust would obtain such Secondary
Insurance only if, in the Advisor's view, it would be economically advantageous
for the Trust to do so.

   The Trust may purchase California municipal obligations covered by Original
Issue Insurance provided by AMBAC Indemnity Corporation ("AMBAC"), Bond
Investors Guaranty Insurance Company ("BIGI"), Capital Markets Assurance
Company ("CAPMAC"), Municipal Bond Investors Assurance Corporation ("MBIA"),
Financial Security Assurance Inc. ("FSA") and Financial Guaranty Insurance
Company ("FGIC"); each has received insurance claims-paying ability ratings of
Aaa from Moody's and AAA from S&P. See Appendix B to the statement of
additional information for a description of Moody's and S&P's insurance claims-
paying ability ratings and financial data regarding each of these insurers. The
Trust may also purchase Secondary Insurance and Portfolio Insurance policies
from any of such insurers. In the future, the Trust may purchase California
municipal obligations covered by Original Issue Insurance provided by, and may
purchase Secondary and Portfolio Insurance from, other insurers (not listed
above) whose claims-paying abilities are rated Aaa by Moody's or AAA by S&P or,
if unrated, are of comparable credit quality in the view of the Advisor. Any
payments received from an insurer, whether the insurance is obtained by the
Trust or by other parties, is treated for Federal income tax purposes and for
purposes of California taxes in the same manner as if the payments were
received directly from the issuer of the California municipal obligations. See
"Taxes".

   The Advisor anticipates that a majority of insured tax-exempt California
municipal obligations purchased by the Trust will be insured under policies
obtained by parties other than the Trust. The Trust does not pay the premiums
for such policies; rather the cost of such policies may be reflected in a
higher purchase price for such insured California municipal obligations.
Accordingly, the yield on such California municipal obligations may be lower
than that on equivalent uninsured California municipal obligations. The cost of
insurance purchased by the Trust will increase its expenses, and the yield on
the Trust's portfolio will be reduced accordingly.

   In the event the claims-paying ability rating of an insurer of California
municipal obligations in the Trust's portfolio were to be lowered from Aaa or
AAA (in the case of Moody's or S&P, respectively), or if the Advisor
anticipates such a lowering or otherwise does not believe an insurer's claims-
paying ability merits its existing triple-A rating, the Trust may seek to
obtain additional insurance from an insurer whose claims-paying ability is
rated Aaa by Moody's or AAA by S&P or, if the Advisor determines that the costs
of obtaining such additional

                                       15
<PAGE>

insurance outweigh the benefits, the Trust may elect not to obtain additional
insurance. In making such determination, the Advisor will consider the costs of
the additional insurance, the new claims-paying ability rating and financial
condition of the existing insurer and the creditworthiness of the issuer and/or
guarantor of the underlying California municipal obligations. The Advisor may
also determine not to purchase additional insurance in such circumstances if it
believes that the insurer is taking steps which will cause its triple-A claims-
paying ability rating to be restored promptly. The foregoing policies also will
be applied in the case of insurers whose claims-paying abilities are not rated
but which are determined by the Advisor to be comparable to Aaa or AAA. See
"Investment Objective and Policies".

   Although the Advisor periodically reviews the financial condition of each
insurer, there can be no assurance that the insurers will be able to honor
their obligations in all circumstances. The Trust cannot predict the
consequences of a state takeover of an insurer's obligations and, in
particular, whether such an insurer (or its state regulatory agency or a
subsequent purchaser) could or would honor all of the insurer's contractual
obligations including any outstanding insurance contracts insuring the timely
payment of principal and interest on California municipal obligations. The
Trust cannot predict the impact which such events might have on the market
values of such California municipal obligations. In the event of a default by
an insurer on its obligations in respect of any California municipal
obligations in the Trust's portfolio, the Trust would look to the issuer and/or
guarantor of the relevant California municipal obligation for payments of
principal and interest and such issuer and/or guarantor may not be rated Aaa by
Moody's or AAA by S&P or, in the view of the Advisor, be of equivalent credit
quality. Accordingly, the Trust could be exposed to greater risk of non-payment
in such circumstances, which could adversely affect the Trust's net asset value
and the market price per common share. Alternatively, the Trust could elect to
dispose of such California municipal obligations; however, the market prices
for such California municipal obligations may be lower than the Trust's
purchase price for them and the Trust could sustain a capital loss as a result.
Capital losses incurred by the Trust which are not offset by capital gains may
adversely affect the Trust's net asset value and the Trust's ability to return
$15 per common share outstanding to investors on or about December 31, 2008.

   Although the insurance on California municipal obligations reduces financial
or credit risk in respect of the insured obligations (i.e., the possibility
that owners of the insured tax-exempt California municipal obligations will not
receive timely scheduled payments of principal or interest), insured tax-exempt
California municipal obligations remain subject to market risk (i.e.,
fluctuations in market value as a result of changes in prevailing interest
rates). Accordingly, insurance on California municipal obligations does not
insure the market value of the Trust's assets or the net asset value or the
market price for the common shares. Furthermore, insurance, while guaranteeing
scheduled payments of principal and interest on a timely basis, will not make
accelerated payments of principal and interest on California municipal
obligations where the terms of the instrument governing such California
municipal obligations require acceleration in the event of a default. In
general, the Trust does not intend to hold California municipal obligations in
its portfolio which are covered only by Portfolio Insurance unless the Trust
has an irrevocable option to obtain permanent insurance covering such
California municipal obligations from the insurer providing the Portfolio
Insurance or such California municipal obligations mature by their terms on or
before December 31, 2008.

   As of February 4, 2000, approximately 100% of the market value of the
Trust's portfolio was invested in long-term California municipal obligations.
All of such long-term California municipal obligations are rated Aaa by Moody's
or AAA by S&P or are insured by an insurer with a claims-paying ability rating
of Aaa by Moody's or AAA by S&P or guaranteed by an entity with such a rating.
As described under "Description of New Preferred Shares--Rating Agency
Guidelines and Asset Coverage," in calculating the discounted value of insured
California municipal obligations held in the Trust's portfolio for the purpose
of determining compliance with certain rating agency guidelines applicable to
the Trust's preferred shares, the Trust may, in certain circumstances, utilize
the insurance claims-paying ability rating of an insurer of a municipal
obligation or the rating of a guarantor thereof in lieu of the Moody's or S&P's
rating on the underlying municipal obligation.

                           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 or California income tax. For
additional investment practices, see "Investment Policies and Techniques" in
the statement of additional information. 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 (the Bond Buyer Municipal Bond Index or such other index as may be
specified in the Articles Supplementary) 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 California 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 Advisor'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

                                       17
<PAGE>

"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 California 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, California 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.

                                       18
<PAGE>

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. Credit risk should be low for the Trust because it
invests primarily in insured California municipal obligations.

California Municipal Obligations Market Risk

   Investing in the market for California municipal obligations involves
certain risks. The amount of public information available about the California
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 Advisor than a
stock fund or taxable bond fund. The secondary market for California 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.

State-specific Risk

   Because the Trust invests primarily in a portfolio of California municipal
obligations, the Trust is more susceptible to political, economic, regulatory
or other factors affecting issuers of California municipal obligations than a
fund that does not invest primarily in the obligations of such issuers.
California State and local government obligations may be adversely affected by
developments within the State of California and the nation as a whole. Through
popular initiative and legislative activity, the ability of the State of
California to raise money through property taxes and to increase spending has
been the subject of considerable debate and change in recent years. Various
State constitutional amendments, for example, have been adopted which have the
effect of limiting property tax and spending increases, while legislation has
sometimes added to these limitations and has at other times sought to reduce
their impact. To date, these constitutional, legislative and budget
developments do not appear to have severely decreased the ability of the State
and local governments to pay principal and interest on their obligations. It
can be expected that similar types of State legislation or

                                       19
<PAGE>

constitutional proposals will continue to be introduced. The impact of future
developments in these areas is unclear. See "Investment Objective and
Policies--Description of California Municipal Obligations" in the statement of
additional information.

Non-diversification Risk

   The Trust is classified as a "non-diversified" fund, which means that the
Trust may invest a greater portion of its assets in a more limited number of
issuers than a "diversified" fund. As a result, the Trust may be subject to
greater risk than a diversified fund because changes in the financial condition
or market assessment of a single issuer may cause greater fluctuation in the
net asset value of the Trust.

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 California municipal obligations with maturities on or about its
termination date, and shorter term California municipal obligations generally
pay lower rates of interest than longer term California 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 Advisor. 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 Advisor

   BlackRock Advisors, Inc. acts as the Trust's investment advisor. BlackRock
Advisors, Inc., together with its investment advisory subsidiaries, is a global
asset management firm with assets of approximately $165 billion under
management as of December 31, 1999. The Advisor has its principal office at 400
Bellevue Parkway, Wilmington, Delaware 19809. BlackRock Advisors and its
subsidiaries constitute the asset management arm of PNC Bank, N.A., and
together have over 684 employees. The Advisor and its affiliates provide fixed
income, liquidity, equity, alternative investment, and risk management products
for clients worldwide. As of December 31, 1999, the Advisor managed
approximately $86 billion in various fixed income sectors, including $8 billion
in municipal securities. The Advisor and its affiliates also manage 13 closed-
end, six open-end and six money market municipal funds. In addition, the
Advisor manages portfolios of municipal securities for large insurance
companies and high net worth individuals.


                                       20
<PAGE>

   As a result of an internal reorganization effective January 1, 2000,
BlackRock Advisors, Inc. has replaced BlackRock Financial Management Inc. as
investment advisor of the Trust. The investment management and other personnel
responsible for providing services to the Trust did not change as a result of
the reorganization. BlackRock Financial Management, Inc. is a wholly-owned
subsidiary of BlackRock Advisors, Inc.

Investment Philosophy

   The Advisor'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 Advisor 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
Advisor's extensive personnel and technology resources are the key drivers of
the investment philosophy.

   The Advisor's Municipal Bond Team. The Advisor uses a team approach to
managing municipal portfolios. The Advisor 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 Advisor'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 Advisor. Mr. Klingert is a senior
portfolio manager and head of municipal bonds at the Advisor, a position he has
held since joining the Advisor in 1991. Mr. Klingert has over 15 years of
experience in the municipal market. Prior to joining the Advisor, Mr. Klingert
was an Assistant Vice President in the Unit Investment Trust Department at
Merrill Lynch, Pierce, Fenner & Smith Incorporated, 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 Advisor for
over two years and is a member of the Advisor's Investment Strategy Group.
Prior to joining the Advisor 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 Advisor's municipal bond portfolio management team and
Investment Strategy Group. Prior to joining the Advisor in 1999 as a Vice
President, Mr. McGinley worked at Prudential Securities in municipal research
and strategy as a Vice President since 1996 and as an Associate Vice President
from 1993 to 1996.

   The Advisor's municipal bond portfolio managers are responsible for 27
municipal bond portfolios, valued as of December 31, 1999 at approximately $5
billion, plus approximately an additional $3 billion in municipal bonds held
across portfolios with broader investment mandates. The team is responsible for
portfolios with a variety of investment objectives and constraints, including
national funds and state-specific funds. As of December 31, 1999, the team
managed 13 closed-end municipal funds with over $3 billion in assets.

   The Advisor's Investment Process. The Advisor has in-depth expertise in the
fixed income market. The Advisor applies the same risk-controlled, active
sector rotation style (discussed below) to the management process for all of
its fixed income portfolios. The Advisor 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 Advisor.

   The Advisor's portfolio management process emphasizes research and analysis
of specific sectors and securities, not interest rate speculation. The Advisor
believes that market-timing strategies can be highly volatile and potentially
produce inconsistent results. Instead, the Advisor thinks that value over the
long-term is

                                       21
<PAGE>

best achieved through a risk-controlled approach, focusing on sector
allocation, security selection and yield curve management (discussed below).

   In the municipal market, the Advisor believes one of the most important
determinants of value is supply and demand. The Advisor'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 Advisor 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 Advisor 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 as
the Advisor. 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 as the
Advisor, specializing in the credit analysis of municipal securities.

   The Advisor'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 Advisor's analytic process focuses on anticipating changes in
credit trends before market recognition. Credit research is a critical element
of the Advisor's municipal process. The Advisor'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 Advisor 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 Advisor 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 Advisor, 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 Advisor. The advisory agreement provides that the Trust shall
pay to the Advisor 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 included in determining the Trust's average weekly net asset value.

   Although the Advisor 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 Advisor are not exclusive and the Advisor 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 Advisor is not liable to the Trust or any of the
Trust's stockholders for any act or omission by the Advisor 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 Advisor, its partners, officers, employees, agents and control
persons for

                                       22
<PAGE>

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 Advisor, 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 Merrill Lynch, Pierce, Fenner & Smith

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

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:

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

  . 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 included 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.

                        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 C-
1, C-2 and C-3 to the statement of additional information.

   The Preferred Shares of each series are shares of preferred stock of the
Trust. Preferred Shares entitle their holders to receive dividends when, as and
if declared by the board of directors, out of funds legally available therefor.
The rate per annum on which dividends are paid may vary from dividend period to
dividend period for each series of Preferred Shares. In general, the applicable
rate for a particular dividend period for a series of Preferred Shares will be
determined by an auction conducted on the day before the start of the dividend
period. Existing holders and potential holders of Preferred Shares may
participate in the auctions. Existing holders desiring to continue to hold all
of their Preferred Shares regardless of the applicable rate resulting from the
auction need not participate. For an explanation of auctions and the method of
determining the applicable rate, see "The Auction". The Trust intends to redeem
all of the Preferred Shares of each series no later than the last dividend
payment date for the series prior to December 31, 2008 (when the Trust will
terminate).

   A dividend payment date and an auction date for the Trust's outstanding
Series W28 Preferred Shares may coincide with a dividend payment date and an
auction date for the Series W7 Preferred Shares (including the New Preferred
Shares). The Series W28 Preferred Shares generally will have a dividend period
of 28 days in length. The Series W7 Preferred Shares (including the New
Preferred Shares) generally will have a dividend period of seven days in
length. The New Series W7 Preferred Shares may have a different dividend period
for the initial dividend period. Either series of Preferred Shares may have a
dividend period different from its normal dividend period if the board of
directors declares a special dividend period for that series.

   The Preferred Shares have a liquidation preference of $25,000 per share plus
an amount equal to accumulated but unpaid dividends plus the premium, if any,
resulting from the designation of a Premium Call Period. A Premium Call Period
is a period that may occur during a special dividend period during which the
Trust must pay a premium in order to redeem Preferred Shares. The Preferred
Shares are fully paid and non-assessable. The Preferred Shares are not
convertible into common shares or other capital stock of the Trust. Holders of
Preferred Shares have no preemptive rights. The Preferred Shares are not
subject to any sinking fund. The Preferred Shares are generally subject to
redemption at the option of the Trust on any dividend payment date for the
respective series (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 C-1, C-2 and C-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."

                                       24
<PAGE>

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 1,062 shares of unissued capital stock as New Preferred Shares.

   The New Preferred Shares will rank the same as the currently outstanding
Preferred Shares as to the payment of dividends and the distribution of assets
upon liquidation. Each New Preferred Share carries one vote on matters that
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 for the New Preferred Shares. 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. The initial
dividend will be paid on       , 2000. Subsequent dividends generally will be
paid on each Thursday. If dividends are payable on a Thursday 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 Articles Supplementary.
In the case of a special dividend period of 35 days or fewer, dividends are
generally payable on the day following the last day of such dividend period. In
the case of a special dividend period of more than 35 but less than 92 days,
dividends generally are payable on the day following the last day of each 30
day period to occur during the dividend period and on the day following the
last day of the dividend period. In the case of a special dividend period of 92
days or more, dividends generally are payable as the Trust may specify in the
notice of special dividend period issued for such special dividend period.

   Dividends will be paid through The Depository Trust Company on each dividend
payment date. DTC, 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 (members of DTC that will act on behalf
of existing or potential holders of Preferred Shares). 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 a Broker-Dealer or a 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 auction,
except as provided below. The dividend rate that results from an auction will
not be greater than the

                                       25
<PAGE>

maximum applicable rate described below. 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 declaring the
special dividend period. During dividend periods for which no Bid Requirements
are specified, there will be no minimum applicable rate. "Bid Requirements" may
include, with respect to any special dividend period of longer than 91 days,
the requirement that bids be expressed as a spread over a specified reference
index or reference security, any minimum applicable rate and the frequency of
dividend payments during such special dividend period.

   The maximum applicable rate for any regular dividend payment period will be
the applicable percentage (set forth in the table below) of the higher of (i)
the 30-day "AA" Composite Commercial Paper Rate and (ii) the Taxable Equivalent
of the Short-Term Municipal Bond Rate. In the case of a special dividend
period, the maximum applicable rate will be the applicable percentage of the
Special Dividend Period Reference Rate (which will ordinarily be specified by
the Trust in the notice of the special dividend period) for such dividend
payment period. The applicable percentage is determined on the day that a
notice of a special dividend period is delivered if the notice specifies a
maximum applicable rate for a special dividend period. The applicable
percentage will be determined based on the lower of the credit rating or
ratings assigned to the Preferred Shares by Moody's and S&P. If Moody's or S&P
or both shall not make such rating available, the rate shall be determined by
reference to equivalent ratings issued by a substitute rating agency. If the
Trust has provided notification to the auction agent prior to an auction
establishing the applicable rate for a dividend period that net capital gains
or other taxable income will be included in the dividend determined at such
auction, the applicable percentage will be derived from the column captioned
"Applicable Percentage: Notification" in the table below:

</TABLE>

   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. Under Federal income tax rules applicable to the
Trust, the Trust may, in certain circumstances, allocate net capital gains or
other taxable income to a dividend paid on New Preferred Shares after the
dividend has been paid (a "Retroactive Taxable Allocation"). If a Retroactive
Taxable Allocation is made on the New Preferred Shares, the Trust will, in the
circumstances below, pay to the holders of New Preferred Shares, out of funds
legally available therefor, an additional dividend. The additional dividend
will be in an amount equal to the amount of taxes paid by a holder of New
Preferred Shares on the Retroactive Taxable Allocation, provided that the
additional dividend will be calculated:

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

  .  assuming that no holder of New Preferred Shares is subject to the
     Federal alternative minimum tax with respect to dividends received from
     the Trust; and

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

                                       26
<PAGE>

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.

   An additional dividend will be paid following a Retroactive Taxable
Allocation in the following circumstances:

  . if a Retroactive Taxable Allocation is made in connection with a dividend
    period of 28 days or fewer and the Trust did not give advanced notice of
    the Retroactive Taxable Allocation to the Auction Agent solely because of
    the redemption of all or a portion of the New Preferred Shares or the
    liquidation of the Trust; or

  . if a Retroactive Taxable Allocation is made in connection with a dividend
    period of 35 days or more.

In no other instance will the Trust be required to make payments to holders of
New Preferred Shares to offset the tax effect of a Retroactive Taxable
Allocation.

   The Trust 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. The Trust will pay, out of legally
available funds, any additional dividend due on all Retroactive Taxable
Allocations made during the fiscal year in question, within 30 days after such
notice is given to the auction agent.

   Restrictions on Dividends and Other Distributions. While the New Preferred
Shares are outstanding, the Trust generally may not declare, pay or set apart
for payment, any dividend or other distribution in respect of its common
shares. In addition, the Trust may not call for redemption or redeem any of its
common shares. However, the Trust is not confined by the above restrictions if:

  . 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);

  . 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;

  . any additional dividend required to be paid on or before the date of such
    declaration has been paid; and

  . 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.

   The Trust generally 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 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 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,
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. The notice will 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 as specified in such
notice. The Trust may not request a special dividend period unless sufficient
clearing bids

                                       27
<PAGE>

were made in the most recent auction. In addition, full cumulative dividends,
any amounts due with respect to mandatory redemptions and any additional
dividends payable prior to such date must be paid in full. The Trust also must
have 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 also will 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. If advisable, the
Broker-Dealer(s) will determine the specific redemption provisions (such as the
designation of a Premium Call Period or a Non-Call Period) 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. The Trust is required to maintain (a) a Discounted
Value of its portfolio equal to the Preferred Shares Basic Maintenance Amount
and (b) the 1940 Act Preferred Shares Asset Coverage. If the Trust fails to
maintain such asset coverage amounts and does not timely cure such failure 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 number of Preferred Shares that must be
redeemed in order to cure such failure will be allocated pro rata among the New
Preferred Shares and the other outstanding Preferred Shares of the Trust. 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. The Trust, at its option, may redeem the New Preferred
Shares, in whole or in part, out of funds legally available therefor. Any
optional redemption will occur on a dividend payment date at the optional
redemption price per share of $25,000 per share plus an amount equal to
accumulated but unpaid dividends to the date fixed for redemption, plus the
premium, if any, resulting from the designation of a Premium Call Period. No
New Preferred Shares may be redeemed during a Non-Call Period or if the
redemption would cause the Trust to violate the 1940 Act or Maryland law. In
addition, holders of New Preferred Shares may be entitled to receive additional
dividends if the redemption causes the Trust to make a Retroactive Taxable
Allocation. The Trust has the authority to redeem the New Preferred Shares for
any reason. The Trust intends to redeem all of its outstanding preferred shares
(including the New Preferred Shares) prior to the last dividend payment date in
respect of each series prior to December 31, 2008 (when the Trust will
terminate).

Liquidation

   If the Trust is liquidated, the holders of outstanding New Preferred Shares
will receive the liquidation preference on the New Preferred Shares, plus all
accumulated but unpaid dividends, plus (i) the premium, if any, resulting from
the designation of a Premium Call Period and (ii) any applicable additional
dividends payable before any payment is made to the common shares. The holders
of New Preferred Shares will be entitled to receive these amounts from the
assets of the Trust available for distribution to its shareholders. In
addition, the rights of holders of New Preferred Shares to receive these
amounts are 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 as described, the holders of New Preferred Shares will
have no right or claim to any of the remaining assets of the Trust.

                                       28
<PAGE>

   For purposes of the foregoing paragraph, a voluntary or involuntary
liquidation of the Trust does not include:

  . the sale of all or substantially all the property or business of the
    Trust;

  . the merger or consolidation of the Trust into or with any other
    corporation; or

  . the merger or consolidation of any other corporation into or with the
    Trust.

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 ineligible assets included in the
Trust's 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 the Preferred Shares then
outstanding and (b) certain accrued and projected payment obligations of the
Trust.

   The Trust is also required under the 1940 Act to maintain asset coverage of
at least 200% with respect to senior securities which are equity shares,
including the New Preferred Shares ("1940 Act Preferred Shares Asset
Coverage"). The Trust's 1940 Act Preferred Shares Asset Coverage is tested as
of the last business day of each month in which any senior equity securities
are outstanding. The minimum required 1940 Act Preferred Shares Asset Coverage
amount of 200% may be increased or decreased if the 1940 Act is amended. Based
on the composition of the portfolio of the Trust and market conditions as of
February 4, 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 $565,500, would have
been computed as follows:

<TABLE>
     <S>                                          <C> <C>          <C> <C>
       Value of Trust assets less liabilities
         not constituting senior securities         = $271,859,819   = 260%
         ----------------------------------           ------------
     Senior securities representing indebtedness      $104,550,000
                        plus
      liquidation value of the preferred shares
</TABLE>

   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, the Trust is required under its Articles
Supplementary to have Deposit Securities with maturity or tender payment dates
not later than the next dividend payment date for the New Preferred Shares
(collectively, "Dividend Coverage Assets") 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 the
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

                                       29
<PAGE>

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 needs to comply with the S&P
Minimum Liquidity Level only for so long as S&P rates the New Preferred Shares.
The Minimum Liquidity Level is tested as of each Valuation Date (ordinarily
every Friday).

   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 Advisor 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.

   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. 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, the sole remedy of holders of
outstanding preferred shares of the Trust 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 as described above, would constitute a majority
of the board of directors. The holders of preferred shares of the Trust 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 pays in full all dividends payable on all outstanding preferred
shares of the Trust, 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.

                                       30
<PAGE>

   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, in the case of
  shares of preferred stock on parity with the Preferred Shares, 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 a 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 will 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 or consent of the
holders of at least a majority of the shares of each series adversely affected.
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. However, to the extent
permitted by the 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. 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 of the holders of common
shares expressly set forth in the Trust's charter.

   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 in this
prospectus, the applicable rate for the New Preferred Shares for each dividend
period after the initial dividend period will be the rate that results from an
auction conducted as set forth in the Trust's charter and summarized below. In
such an auction, persons determine to hold or offer to sell or, based on
dividend rates bid by them, offer to purchase or sell New Preferred Shares. See
the Articles Supplementary included in the statement of additional information
for a more complete description of the auction process.

                                       31
<PAGE>

   Auction Agency Agreement. The Trust will enter into an 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 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 will pay to each Broker-Dealer after each auction, from
funds provided by the Trust, a service charge at the annual rate of 1/4 of 1%,
in the case of any auction before a dividend period of 28 days or less, or a
percentage agreed to by the Trust and the Broker-Dealers, in the case of any
auction before a dividend period of 35 days or longer, of the purchase price of
New Preferred Shares placed by a Broker-Dealer at the auction.

   The Trust may request the auction agent to terminate one or more Broker-
Dealer Agreements at any time upon five days' notice, 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 beneficial owner of
New Preferred Shares may submit the following types of orders with respect to
New Preferred Shares to that Broker-Dealer:

     1. Hold order--indicating its desire to hold New Preferred Shares
  without regard to the applicable rate for the next dividend period.

     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 is less than the rate or spread specified in the 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.

   A beneficial owner of New Preferred Shares may submit different types of
orders to its Broker-Dealer with respect to New Preferred Shares then held by
the 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 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
ordinarily be deemed to have submitted a hold order to its Broker-Dealer.
However, 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 constitutes an irrevocable offer to sell the New Preferred
Shares subject to the sell order. A beneficial owner that offers to become the
beneficial owner of additional New Preferred Shares is, for purposes of such
offer, a potential holder as discussed below.

   A potential holder is either 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 a beneficial owner that wishes to purchase additional New
Preferred Shares. A potential holder may submit bids to its Broker-Dealer in
which it offers to

                                       32
<PAGE>

purchase New Preferred Shares at $25,000 per share if the applicable rate for
the next dividend period is not less than the rate specified in such bid. A bid
placed by a potential holder specifying a rate higher than the maximum
applicable rate on the auction date 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 holders to the auction agent.
They will designate themselves (unless otherwise permitted by the Trust) as
existing holders of shares subject to orders submitted or deemed submitted to
them by beneficial owners. They will designate themselves as potential holders
of shares subject to orders submitted to them by potential holders. However,
neither the Trust nor the auction agent will be responsible for a Broker-
Dealer's failure to comply with these procedures. 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 the same way as an order placed with a Broker-
Dealer by a beneficial owner or potential holder. Similarly, any failure by a
Broker-Dealer to submit to the auction agent an order for any New Preferred
Shares held by it or customers who are beneficial owners will be treated 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.

   There are sufficient clearing bids in an auction if the number of shares
subject to bids submitted or deemed submitted to the auction agent by Broker-
Dealers for 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 for existing holders. If there are sufficient clearing bids, 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 there are not sufficient clearing bids, the applicable rate for the next
dividend period will be the maximum applicable rate on the auction date. If
this happens, beneficial owners of New Preferred Shares that have submitted or
are deemed to have submitted sell orders may not be able to sell in the 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
following the auction will automatically be the same length as the preceding
dividend period. The applicable rate for the next dividend period will then 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 or corporate
    income tax rate (whichever is higher) then applicable to ordinary income
    (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 "30-day "AA' Composite Commercial Paper Rate" is the 30-day rate on
commercial paper issued by corporations whose bonds are rated AA by S&P as made
available by the Federal Reserve Bank of New York or, if such rate is not made
available by the Federal Reserve Bank of New York, the arithmetical average of
such rates as quoted to the auction agent by Merrill Lynch, Pierce, Fenner &
Smith Incorporated or such other commercial paper dealer as may be appointed by
the Trust.

   "Taxable Equivalent of the Short-Term Municipal Bond Rate" means 90% of an
amount equal to the per annum rate payable on taxable bonds in order for such
rate, on an after-tax basis, to equal the per annum rate

                                       33
<PAGE>

payable on tax-exempt bonds issued by "high grade" issuers as determined in
accordance with the procedures set forth in the Articles Supplementary.

   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
(which is also a dividend payment date) after the auction date through DTC.
Purchasers will make payment through their Agent Members in same-day funds to
DTC against delivery to their respective Agent Members. DTC will make payment
to the sellers' Agent Members in accordance with DTC'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 Wednesday,
and each subsequent dividend period will normally begin on the following
Thursday.

   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 will, in the case of a dividend period of 28 days or less,
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 not later than the dividend
payment date before the auction date. 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, will be required to notify its
customers who are beneficial owners and potential holders 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. 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:

  . pursuant to a bid or sell order placed with the auction agent in
    accordance with the auction procedures;

  . to a Broker-Dealer; or

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

                                       34
<PAGE>

provided, however, that

  . 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 if such Broker-Dealer remains the existing holder of
    the shares; and

  . 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 will advise the auction agent of such transfer.

                                     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, and intends to distribute at least 90% of its net
investment income (including taxable income, tax-exempt interest income 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 will, in the case of a dividend period of
28 days or less, and may, in the case of a dividend period of 35 days or more,
notify holders of 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,
including New Preferred Shares, 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 income 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 advisor about Federal income tax matters.

California Tax Matters

   In the opinion of California tax counsel, dividends paid by the Trust and
designated by it as exempt-interest dividends are exempt from California state
personal income tax to the extent such dividends are derived from interest
payments on municipal obligations exempt from California state personal income
tax. The Trust may only designate and pay exempt-interest dividends if, as the
Trust intends, at least 50% of the value of its assets at the close of each
quarter of its taxable year consists of obligations with respect to which, when
held by an individual, the interest is exempt from taxation by the state of
California. The Trust's distributions of short-term capital gain are treated as
ordinary income. Distributions of long-term capital gain are treated as long-
term capital gain but are subject to tax at ordinary income rates because the
California state personal income tax law does not provide a preferential tax
rate for capital gains. Investment in the New Preferred Shares may not be
appropriate for corporations subject to California franchise tax or California
corporate income tax.

                        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 Advisor. 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 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 have the Trust 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 1,062 shares of unissued capital stock as New Preferred Shares.

Common Shares

   The Trust's charter provides that the Trust will terminate on December 31,
2008, without stockholder approval. In connection with such termination, the
Trust will liquidate all of its assets and distribute to holders of outstanding
common shares the net proceeds from such liquidation after making appropriate
provision for any liabilities of the Trust and the payment of any liquidation
preferences and accumulated but unpaid dividends on any outstanding shares of
Preferred Stock. Prior to such termination, however, the board of directors of
the Trust will consider whether it is in the best interests of stockholders to
terminate and liquidate the Trust on December 31, 2008 without stockholder
approval notwithstanding the foregoing provision of the charter. In considering
this matter, the board of directors will take into account, among other
factors, the adverse effect which capital losses realized upon disposition of
securities in connection with liquidation (if any such losses are anticipated)
would have on the Trust and its stockholders. In the event that the board of
directors determines that under the circumstances, termination and liquidation
of the Trust on December 31, 2008 without a stockholder vote would not be in
the best interests of stockholders, the board of directors will call a special
meeting of stockholders to consider an appropriate amendment to the Trust's
charter. The Trust's charter would require the affirmative vote of the holders
of at least 75% of outstanding shares of capital stock to approve such an
amendment. The foregoing provisions of the Trust's charter are governed by the
laws of the State of Maryland and not the 1940 Act. All common shares are equal
as to dividends, assets and voting privileges and have no conversion,
preemptive or other subscription rights.

   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.

   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 since September
18, 1992 under the symbol "BFC."

   At February 4, 2000, there were 10,407,093 common shares of the Trust issued
and outstanding, and the net asset value per common share was $16.31 and the
closing price per common share on the NYSE was $14.438.

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 1,062 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 NYSE. 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 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) 66 2/3% 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.

                                       38
<PAGE>

   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.

   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
Advisor 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 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 the underwriters engages in transactions
with, and perform services for, the Trust in the ordinary course of business.

                         DISBURSING AGENT AND REGISTRAR

   The transfer agent, dividend disbursing agent and registrar for the New
Preferred Shares will be Deutsche Bank Group, 4 Albany Street, New York, New
York. The transfer agent, dividend disbursing agent and registrar for the
common shares of the Trust is State Street Bank and Trust Company.

   The table below gives the approximate yield a security must earn at various
income brackets to produce after-tax yields equivalent to those of tax-exempt
bonds yielding from 3.00% to 5.00% under the regular Federal and California
income tax law and tax rates applicable to individuals for 2000.

* Net amount subject to Federal and California 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.

   The combined Federal and California tax brackets are calculated using the
highest California tax rate applicable within each bracket. Taxpayers with
taxable income within such brackets may have lower combined tax brackets and
taxable equivalent yields than those indicated above. The combined tax brackets
assume that California taxes are itemized deductions for federal income tax
purposes. Investors who do not itemize deductions on their federal income tax
return will have a higher combined bracket and higher taxable equivalent yield
than those indicated above. The applicable federal tax rates within the
brackets are 28%, 31%, 36% and 39.6%.

   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 and California income tax, other income received by the
Trust may be taxable. 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 Federal alternative minimum tax. The illustrations assume that the Federal
alternative minimum tax is not applicable and do not take into account any tax
credits that may be available. Finally, it should be noted investment in the
New Preferred Shares may not be as appropriate for corporations subject to
California franchise tax or California corporate income tax.

   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 advisor for additional information.

                       INVESTMENT OBJECTIVE AND POLICIES

     The Trust has not established any limit on the percentage of its portfolio
that may be invested in California municipal obligations subject to the
alternative minimum tax provisions of Federal tax law.  New Preferred Shares may
not be a suitable investment for investors who are subject to the Federal
alternative minimum tax 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 the
alternative minimum tax, and from comparable fully taxable investments, in light
of each such investor's tax position. Special considerations apply to corporate
investors.  Investment in the New Preferred Shares may not be as appropriate for
corporations subject to California franchise tax or California corporate income
tax.  See "Tax Matters."

     The types of California 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 California 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 California municipal
obligations both within a particular classification and between classifications.

     Also included within the general category of California 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.

     Certain California 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 California 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 California 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

                                      S-2
<PAGE>

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 term California municipal obligations also includes obligations, such
as tax-exempt notes, municipal commercial paper and municipal lease obligations,
having relatively short-term maturities. As noted above, however, the Trust
intends to invest its assets in a portfolio of municipal obligations which will
have an average final maturity on or about the Trust's termination date of
December 31, 2008, except in temporary defensive situations in which case
investments in short-term assets may be increased.

                DESCRIPTION OF CALIFORNIA MUNICIPAL OBLIGATIONS

     As described in the Prospectus, except during temporary periods, the Trust
will invest substantially all of its assets in California municipal obligations.
In addition, the specific California municipal obligations in which the Trust
will invest will change from time to time. The Trust is therefore susceptible to
political, economic, regulatory or other factors affecting issuers of California
municipal obligations. The following information constitutes only a brief
summary of a number of the complex factors which may impact issuers of
California municipal obligations and does not purport to be a complete or
exhaustive description of all adverse conditions to which issuers of California
municipal obligations may be subject. Such information is derived from official
statements utilized in connection with the issuance of California municipal
obligations, as well as from other publicly available documents. Such
information has not been independently verified by the Trust, and the Trust
assumes no responsibility for the completeness or accuracy of such information.
The summary below does not include all of the information pertaining to the
budget, receipts and disbursements of the State of California that would
ordinarily be included in various public documents issued thereby, such as an
Official Statement prepared in connection with the issuance of general
obligation bonds of the State of California. Such an Official Statement,
together with any updates or supplements thereto, may generally be obtained upon
request to the Office of the Treasurer of the State of California.

State Indebtedness

     The Treasurer of the State of California (the "State") is responsible for
the sale of debt obligations of the State and its various authorities and
agencies. The State has always paid the principal of and interest on its general
obligation bonds, general obligation commercial paper, lease-purchase debt and
short-term obligations, including revenue anticipation notes and revenue
anticipation warrants, when due.

Capital Facilities Financing

     The State Constitution prohibits the creation of general obligation
indebtedness of the State unless a bond law is approved by a majority of the
electorate voting at a general election or a direct primary. General obligation
bond acts provide that debt service on general obligation bonds shall be
appropriated annually from the State's General Fund and all debt service on
general obligation bonds is paid from the General Fund. Under the State
Constitution, debt service on general obligation bonds is the second charge to
the General Fund after the application of moneys in the General Fund to the
support of the public school system and public institutions of higher education.
Certain general obligation bond programs receive revenues from sources other
than the sale of bonds or the investment of bond proceeds.

     As of October 1, 1999, the State had outstanding $19,630,276,000 aggregate
principal amount of long-term general obligation bonds, and unused voter
authorizations for the future issuance of $12,827,414,000 of long-term general
obligation bonds. This latter figure consists of $4,451,734,000 of authorized
commercial paper notes, described below (of which $814,565,000 was outstanding),
which had not yet been refunded by general obligation bonds, and $8,375,680,000
of other authorized but unissued general obligation debt.

     In its 1999 session, the Legislature passed and the Governor signed five
bond acts, totaling $4.69 billion in new authorizations. These bond acts will be
placed on the March 7, 2000 ballot for voter approval.

                                      S-3
<PAGE>

     Pursuant to legislation enacted in 1995, voter approved general obligation
indebtedness may be issued either as long-term bonds, or, for some but not all
bond acts, as commercial paper notes. Commercial paper notes may be renewed or
may be refunded by the issuance of long-term bonds. The State issues long-term
general obligation bonds from time to time to retire its general obligation
commercial paper notes. Pursuant to the terms of the bank credit agreement
presently in effect supporting the general obligation commercial paper program,
not more than $1.5 billion of general obligation commercial paper notes may be
outstanding at any time; this amount may be increased or decreased in the
future. Commercial paper notes are deemed issued upon authorization by the
respective Finance Committees, whether or not such notes are actually issued. As
of October 1, 1999 the Finance Committees had authorized the issuance of up to
$4,451,734,000 of commercial paper notes; as of that date $814,565,000 aggregate
principal amount of general obligation commercial paper notes was outstanding.

     In addition to general obligation bonds, the State builds and acquires
capital facilities through the use of lease-purchase borrowing. Under these
arrangements, the State Public Works Board, another State or local agency or a
joint powers authority issues bonds to pay for the construction of facilities
such as office buildings, university buildings or correctional institutions.
These facilities are leased to a State agency or the University of California
under a long-term lease which provides the source of payment of the debt service
on the lease-purchase bonds. In some cases, there is not a separate bond issue,
but a trustee directly creates certificates of participation in the State's
lease obligation, which are marketed to investors. Under applicable court
decisions, such lease arrangements do not constitute the creation of
"indebtedness" within the meaning of the Constitutional provisions which require
voter approval. For purposes of this section, "lease-purchase debt" or "lease-
purchase financing" means principally bonds or certificates of participation for
capital facilities where the rental payments providing the security are a direct
or indirect charge against the General Fund and also includes revenue bonds for
a State energy efficiency program secured by payments made by various State
agencies under energy service contracts. Certain of the lease-purchase
financings are supported by special funds rather than the General Fund. The
State had $6,578,874,434 General Fund-supported lease-purchase debt outstanding
at October 1, 1999. The State Public Works Board, which is authorized to sell
lease revenue bonds, had $2,035,434,000 authorized and unissued as of October 1,
1999. Also, as of that date certain joint powers authorities were authorized to
issue approximately $69,500,000 of revenue bonds to be secured by State leases.

     Certain State agencies and authorities issue revenue obligations for which
the General Fund has no liability. Revenue bonds represent obligations payable
from State revenue-producing enterprises and projects, which are not payable
from the General Fund, and conduit obligations payable only from revenues paid
by private users of facilities financed by the revenue bonds. The enterprises
and projects include transportation projects, various public works projects,
public and private educational facilities (including the California State
University and University of California systems), housing, health facilities and
pollution control facilities. There are 17 agencies and authorities authorized
to issue revenue obligations (excluding lease-purchase debt). State agencies and
authorities had $26,008,006,628 aggregate principal amount of revenue bonds and
notes which are non-recourse to the General Fund outstanding as of June 30,
1999.

State Finances and the Budget Process

     The State's fiscal year begins on July 1 and ends on June 30. The State
operates on a budget basis, using a modified accrual system of accounting, with
revenues credited in the period in which they are measurable and available and
expenditures debited in the period in which the corresponding liabilities are
incurred.

     The annual budget is proposed by the Governor by January 10 of each year
for the next fiscal year (the "Governor's Budget"). Under state law, the annual
proposed Governor's Budget cannot provide for projected expenditures in excess
of projected revenues and balances available from prior fiscal years. Following
the submission of the Governor's Budget, the Legislature takes up the proposal.

     Under the State Constitution, money may be drawn from the Treasury only
through an appropriation made by law. The primary source of the annual
expenditure authorizations is the Budget Act as approved by the Legislature and
signed by the Governor. The Budget Act must be approved by a two-thirds majority
vote of each House of the

                                      S-4
<PAGE>

Legislature. The Governor may reduce or eliminate specific line items in the
Budget Act or any other appropriations bill without vetoing the entire bill.
Such individual line-item vetoes are subject to override by a two-thirds
majority vote of each House of the Legislature.

     Appropriations also may be included in legislation other than the Budget
Act. Bills containing appropriations (except for K-14 education) must be
approved by a two-thirds majority vote in each House of the Legislature and be
signed by the Governor.  Bills containing K-14 education appropriations only
require a simple majority vote. Continuing appropriations, available without
regard to fiscal year, may also be provided by statute or the State
Constitution. There is litigation pending concerning the validity of such
continuing appropriations.

     Funds necessary to meet an appropriation need not be in the State Treasury
at the time such appropriation is enacted; revenues may be appropriated in
anticipation of their receipt.

     The moneys of the State are segregated into the General Fund and over 900
special funds, including bond, trust and pension funds. The General Fund
consists of revenues received by the State Treasury and not required by law to
be credited to any other fund, as well as earnings from the investment of state
moneys not allocable to another fund. The General Fund is the principal
operating fund for the majority of governmental activities and is the depository
of most of the major revenue sources of the State. The General Fund may be
expended as a consequence of appropriation measures enacted by the Legislature
and approved by the Governor, as well as appropriations pursuant to various
constitutional authorizations and initiative statutes.

     The Special Fund for Economic Uncertainties ("SFEU") is funded with General
Fund revenues and was established to protect the State from unforeseen revenue
reductions and/or unanticipated expenditure increases. Amounts in the SFEU may
be transferred by the State Controller as necessary to meet cash needs of the
General Fund. The State Controller is required to return moneys so transferred
without payment of interest as soon as there are sufficient moneys in the
General Fund.

     At the time of signing of the 1999 Budget Act, on June 29, 1999, the
Department of Finance projected the SFEU would have a balance of about $1.932
billion at June 30, 1999, compared to the original budgeted amount of $1.1
billion. The 1999 Budget Act projects a balance in the SFEU of $880 million at
June 30, 2000.

Local Governments

     The primary units of local government in California are the counties,
ranging in population from 1,200 in Alpine County to over 9,600,000 in Los
Angeles County. Counties are responsible for the provision of many basic
services, including indigent health care, welfare, jails and public safety in
unincorporated areas. There are also about 470 incorporated cities, and
thousands of special districts formed for education, utility and other services.
The fiscal condition of local governments has been constrained since the
enactment of "Proposition 13" in 1978, which reduced and limited the future
growth of property taxes and limited the ability of local governments to impose
"special taxes" (those devoted to a specific purpose) without two-thirds voter
approval. Counties, in particular, have had fewer options to raise revenues than
many other local government entities, and have been required to maintain many
services.

     In the aftermath of Proposition 13, the State provided aid to local
governments from the General Fund to make up some of the loss of property tax
moneys, including taking over the principal responsibility for funding K-12
schools and community colleges. During the recession, the Legislature eliminated
most of the remaining components of post-Proposition 13 aid to local government
entities other than K-14 education districts by requiring cities and counties to
transfer some of their property tax revenues to school districts. However, the
Legislature also provided additional funding sources (such as sales taxes) and
reduced certain mandates for local services.  Since then the State has also
provided additional funding to counties and cities through such programs as
health and welfare realignment, welfare reform, trial court restructuring, the
COPs program supporting local public safety departments, and various other
measures.

                                      S-5
<PAGE>

     The 1999 Budget Act includes a $150 million one-time subvention from the
General Fund to local agencies for relief from the 1992 and 1993 property tax
shifts.  Legislation has been passed, subject to voter approval at the election
in November, 2000, to provide a more permanent payment to local governments to
offset the property tax shift. In addition, legislation was enacted in 1999 to
provide annually up to $50 million relief to cities based on 1997-98 costs of
jail booking and processing fees paid to counties.

     In 1996, voters approved Proposition 218, entitled the "Right to Vote on
Taxes Act," which incorporates new Articles XIII C and XIII D into the
California Constitution.  These new provisions place limitations on the ability
of local government agencies to impose or raise various taxes, fees, charges and
assessments without voter approval. Certain "general taxes" imposed after
January 1, 1995, must be approved by voters in order to remain in effect.  In
addition, Article XIII C clarifies the right of local voters to reduce taxes,
fees, assessments or charges through local initiatives.  There are a number of
ambiguities concerning the Proposition and its impact on local governments and
their bonded debt which will require interpretation by the courts or the
Legislature. Proposition 218 does not affect the State or its ability to levy or
collect taxes.

State Appropriations Limit

     The State is subject to an annual appropriations limit imposed by Article
XIII B of the State Constitution (the "Appropriations Limit"). The
Appropriations Limit does not restrict appropriations to pay debt service on
voter-authorized bonds.

     Article XIII B prohibits the State from spending "appropriations subject to
limitation" in excess of the Appropriations Limit. "Appropriations subject to
limitation," with respect to the State, are authorizations to spend "proceeds of
taxes," which consist of tax revenues, and certain other funds, including
proceeds from regulatory licenses, user charges or other fees to the extent that
such proceeds exceed "the cost reasonably borne by that entity in providing the
regulation, product or service," but "proceeds of taxes" exclude most state
subventions to local governments, tax refunds and some benefit payments such as
unemployment insurance. No limit is imposed on appropriations of funds which are
not "proceeds of taxes," such as reasonable user charges or fees and certain
other non-tax funds.

     Not included in the Appropriations Limit are appropriations for the debt
service costs of bonds existing or authorized by January 1, 1979, or
subsequently authorized by the voters, appropriations required to comply with
mandates of courts or the federal government, appropriations for qualified
capital outlay projects, appropriations of revenues derived from any increase in
gasoline taxes and motor vehicle weight fees above January 1, 1990 levels, and
appropriation of certain special taxes imposed by initiative (e.g., cigarette
and tobacco taxes). The Appropriations Limit may also be exceeded in cases of
emergency.

     The State's Appropriations Limit in each year is based on the limit for the
prior year, adjusted annually for changes in state per capita personal income
and changes in population, and adjusted, when applicable, for any transfer of
financial responsibility of providing services to or from another unit of
government or any transfer of the financial source for the provisions of
services from tax proceeds to non tax proceeds. The measurement of change in
population is a blended average of statewide overall population growth, and
change in attendance at local school and community college ("K-14") districts.
The Appropriations Limit is tested over consecutive two-year periods. Any excess
of the aggregate "proceeds of taxes" received over such two-year period above
the combined Appropriations Limits for those two years is divided equally
between transfers to K-14 districts and refunds to taxpayers.

     The Legislature has enacted legislation to implement Article XIII B which
defines certain terms used in Article XIII B and sets forth the methods for
determining the Appropriations Limit. California Government Code Section 7912
requires an estimate of the Appropriations Limit to be included in the
Governor's Budget, and thereafter to be subject to the budget process and
established in the Budget Act.

Proposition 98

     On November 8, 1988, voters of the State approved Proposition 98, a
combined initiative constitutional amendment and statute called the "Classroom
Instructional Improvement and Accountability Act." Proposition 98 changed State
funding of public education below the university level and the operation of the
State Appropriations Limit, primarily by guaranteeing K-14 schools a minimum
share of General Fund revenues. Under Proposition 98 (as modified by Proposition
111, which was enacted on June 5, 1990), K-14 schools are guaranteed the greater
of (a) in general, a fixed percent of General Fund revenues ("Test 1"), (b) the
amount appropriated to K-14 schools in the prior year, adjusted for changes in
the cost of living (measured as in Article XIII B by reference to State per
capita personal income) and enrollment ("Test 2"), or (c) a third test, which
would replace Test 2 in any year when the percentage growth in per capita
General Fund revenues from the prior year plus one half of one percent is less
than the percentage growth in State per capita personal income ("Test 3"). Under
Test 3, schools would receive the amount appropriated in the prior year adjusted
for changes in enrollment and per capita General Fund revenues, plus an
additional small adjustment factor. If Test 3 is used in any year, the
difference between Test 3 and Test 2 would become a "credit" to schools which
would be the basis of payments in future years when per capita General Fund
revenue growth exceeds per capita personal income growth. Legislation adopted
prior to the end of the 1988-89 Fiscal Year, implementing Proposition 98,
determined the K-14 schools' funding guarantee under Test 1 to be 40.3 percent
of the General Fund tax revenues, based on 1986-87 appropriations. However, that
percent has been adjusted to approximately 35 percent to account for a
subsequent redirection of local property taxes, since such redirection directly
affects the share of General Fund revenues to schools.

     Proposition 98 permits the Legislature by two-thirds vote of both houses,
with the Governor's concurrence, to suspend the K-14 schools' minimum funding
formula for a one-year period. Proposition 98 also contains provisions
transferring certain State tax revenues in excess of the Article XIII B limit to
K-14 schools.

     In 1992, a lawsuit was filed, called California Teachers' Association v.
Gould, which challenged the validity of these off-budget loans. The settlement
of this case, finalized in July, 1996, provides, among other things, that both
the State and K-14 schools share in the repayment of prior years' emergency
loans to schools. Of the total $1.76 billion in loans, the State is repaying
$935 million by forgiveness of the amount owed, while schools will repay $825
million. The State share of the repayment will be reflected as an appropriation
above the current Proposition 98 base calculation. The schools' share of the
repayment will count as appropriations that count toward satisfying the
Proposition 98 guarantee, or from "below" the current base. Repayments are
spread over the eight-year period of 1994-95 through 2001-02 to mitigate any
adverse fiscal impact.

Tobacco Litigation

     In late 1998, the State signed a settlement agreement with the four major
cigarette manufacturers, which was later ratified by a State court judge having
jurisdiction over a pending lawsuit brought by the State against these
companies. The settlement became final in late September, 1999. Under the
settlement, the companies will pay California governments a total of
approximately $25 billion over a period of 25 years. In addition, payments of
approximately $1 billion per year will continue in perpetuity. Under the
settlement, half of these moneys will be paid to the State and half to local
governments (all counties and the cities of San Diego, Los Angeles, San
Francisco and San Jose). The State's 1999-2000 Budget includes receipt of about
$560 million of these settlement moneys to the General Fund by June 30, 2000.

     The specific amount to be received by the State and local governments is,
however, subject to adjustment for a number of reasons. Various details in the
settlement allow reduction of the companies' payments because of events such as
certain federal government actions, or reductions in cigarette sales. In the
event that any of the companies goes into bankruptcy, the State could seek to
terminate the agreement with respect to those companies filing bankruptcy
actions thereby reinstating all claims against those companies. The State may
then pursue those claims in the bankruptcy litigation, or as otherwise provided
by law.

1999-2000 Fiscal Year Budget

     On January 8, 1999, Governor Davis released his proposed budget for Fiscal
Year 1999-00 (the "January Governor's Budget"). The January Governor's Budget
generally reported that general fund revenues for FY 1998-99 and FY 1999-00
would be lower than earlier projections (primarily due to weaker overseas
economic conditions perceived in late 1998), while some caseloads would be
higher than earlier projections. The January Governor's Budget proposed $60.5
billion of general fund expenditures in FY 1999-00, with a $415 million SFEU
reserve at June 30, 2000.

     The 1999 May Revision showed an additional $4.3 billion of revenues for
combined fiscal years 1998-99 and 1999-00. The completion of the 1999 Budget Act
occurred in a timely fashion. The final Budget Bill was adopted by the
Legislature on June 16, 1999, and was signed by the Governor on June 29, 1999
(the "1999 Budget Act"), meeting the Constitutional deadline for budget
enactment for only the second time in the 1990's.

     The final 1999 Budget Act estimated General Fund revenues and transfers of
$63.0 billion, and contained expenditures totaling $63.7 billion after the
Governor used his line-item veto to reduce the legislative Budget Bill
expenditures by $581 million (both General Fund and Special Fund). The 1999
Budget Act also contained expenditures of $16.1 billion from special funds and
$1.5 billion from bond funds. The Administration estimated that the SFEU would
have a balance at June 30, 2000, of about $880 million. Not included in this
amount was an additional $300 million which (after the Governor's vetoes) was
"set aside" to provide funds for employee salary increases (to be negotiated in
bargaining with employee unions), and for litigation reserves. The 1999 Budget
Act anticipates normal cash flow borrowing during the fiscal year.


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

          (2) issue senior securities other than (a) preferred stock 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 stock (including borrowing money, including on margin
     if margin securities are owned and through entering into reverse repurchase
     agreements) not in excess of 33 1/3% 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

                                      S-8
<PAGE>

     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 (2);

          (3) 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;

          (4) 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;

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

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

          (7) 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

          (8) 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.

                                      S-9
<PAGE>

     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 Advisor 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 California 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
California 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 California municipal obligations (whether
or not it holds such securities in its portfolio). For the same purposes the
Trust may also sell puts on California municipal obligations financial indices
and puts on futures contracts on California 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 Advisor; and (iv) the obligation to meet additional variation
margin or other payment requirements.  See Appendix A "General Characteristics
and Risks of Hedging Transactions."

                                      S-10
<PAGE>

     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
Advisor 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.

                                     S-11
<PAGE>

     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
California municipal obligations on a "when-issued" basis and may purchase or
sell California 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 California 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 Advisor, 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.

                                     S-12
<PAGE>

     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.

                            MANAGEMENT OF THE TRUST

     The officers of the Trust manage its day to day operations. The officers
are directly responsible to the Trust's board of directors which sets broad
policies for the Trust and chooses its officers. The following is a list of the
directors and officers of the Trust and a brief statement of their present
positions and principal occupations during the past five years. Directors who
are interested persons of the Trust (as defined in the 1940 Act) are denoted by
an asterisk (*). The business address of the Advisor is 400 Bellevue Parkway,
Wilmington, Delaware 19809. The business address of the Trust and its board
members and officers is 345 Park Avenue, New York, New York 10154, unless
specified otherwise below. The directors listed below are either trustees or
directors of other closed-end funds in which BlackRock Advisors or an affiliate
acts as investment advisor.

                     PORTFOLIO TRANSACTIONS AND BROKERAGE

     The Advisor 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 the 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 Advisor 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 Advisor'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 amount of difficulty in executing the order, and the
best net price. There are many instances when, in the judgment of the Advisor,
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
Advisor, absent special circumstances, to pay higher commissions to a firm
because it has supplied such research or other services.

     The Advisor 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 Advisor, and
does not reduce the Advisor's normal research activities in rendering investment
advice. It is possible that the Advisor'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 Advisor
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 Advisor in its discretion in
accordance with the accounts' various investment objectives. 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 Advisor'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 approximately 100%
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

                                     S-19
<PAGE>

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 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 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.

     Securities Depository. The Depository Trust Company will act as 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 DTC. 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
any 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

                                     S-20

<PAGE>

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 28 days or less, or a percentage agreed to by the Trust and the
Broker-Dealers in the case of any auction immediately preceding a dividend
period of 35 days 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 actions 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 dividends on preferred shares
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.

                                      S-21
<PAGE>

     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 NYSE, 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 NYSE, (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 Subchapter M of the Internal Revenue Code of 1986, as amended (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.

                                      S-22
<PAGE>

     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 interest 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.  Under the Code, at the
close of each quarter of its taxable year, if at least 50% of the value of the
Trust's 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

                                      S-23
<PAGE>

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 and net
capital gain allocable to the Trust's Preferred Shares will depend upon the
amount of such income and gain 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 income, 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
holders 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

                                      S-24
<PAGE>

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 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 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 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

                                      S-25
<PAGE>

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 Federal alternative
minimum tax. Shareholders are advised to consult their own tax advisors for more
detailed information concerning the Federal income tax consequences of
purchasing, holding and disposing of Trust shares.

                          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 Advisor'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 the 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
<PAGE>

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 Advisor
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

                                      A-2
<PAGE>

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
Advisor'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.

                                                                      APPENDIX B

                               INSURANCE RATINGS

     The Trust will purchase or obtain insurance in respect of municipal
obligations only from insurers having claims-paying ability ratings of Aaa from
Moody's Investors Service,  ("Moody's") and AAA from Standard & Poor's ("S&P")
or, if unrated, which are viewed by the Advisor to have similar claims-paying
abilities.

     A Moody's insurance claims-paying ability rating is an opinion of the
ability of an insurance company to repay punctually senior policyholder
obligations and claims. An insurer with an insurance claims-paying ability
rating of Aaa is adjudged by Moody's to be of the best quality. In the opinion
of Moody's, the policy obligations of an insurance company with an insurance
claims-paying ability rating of Aaa carry the smallest degree of credit risk
and, while the financial strength of these companies is likely to change, such
changes as can be visualized are most unlikely to impair the company's
fundamentally strong position. An S&P insurance claims-paying ability rating is
an assessment of an operating insurance company's financial capacity to meet
obligations under an insurance policy in accordance with the terms. An insurer
with an insurance claims-paying ability rating of AAA has the highest rating
assigned by S&P. Capacity to honor insurance contracts is adjudged by S&P to be
extremely strong and highly likely to remain so over a long period of time.

     An insurance claims-paying ability rating by Moody's or S&P does not
constitute an opinion on any specific contract in that such an opinion can only
be rendered upon the review of the specific insurance contract.  Furthermore, an
insurance claims-paying ability rating does not take into account deductibles,
surrender or cancellation penalties or the timeliness of payment; nor does it
address the ability of a company to meet non-policy obligations (i.e., debt
contracts).

     The assignment of ratings by Moody's or S&P to debt issues that are fully
or partially supported by insurance policies, contracts or guarantees is a
separate process from the determination of claims-paying ability ratings. The
likelihood of a timely flow of funds from the insurer to the trustee for the
bondholders is a key element in the rating determination for such debt issues.

     Each of AMBAC Indemnity Corporation ("AMBAC"), Municipal Bond Investors
Assurance Corporation ("MBIA") and its subsidiaries, Bond Investors Guaranty
Insurance Company ("BIGI") and Capital Markets Assurance Company ("CAPMAC"),
Financial Guaranty Insurance Company  ("FGIC") and Financial Security Assurance,
Inc. ("FSA") has a claims-paying ability rating of Aaa from Moody's and AAA from
S&P, and the Trust expects to purchase insurance from any such firm in respect
of particular municipal obligations.

     AMBAC has received a letter ruling from the Internal Revenue Service which
holds in effect that insurance proceeds representing maturing interest on
defaulted municipal obligations paid by AMBAC to municipal bond funds
substantially similar to the Trust, under policy provisions substantially
identical to the policy described herein, will be excludable from Federal gross
income under Section 103(a) of the Internal Revenue Code.

     As of September 30, 1999, AMBAC's insured portfolio (unaudited) was
approximately $232 billion supported by approximately $4.8 billion in claims
paying resources (unaudited).

     As of September 30, 1999, MBIA's insured portfolio (unaudited) was
approximately $396 billion supported by approximately $8.3 billion in claims
paying resources (unaudited).

     As of September 30, 1999, FGIC's insured portfolio (unaudited) was
approximately $136 billion supported by approximately $2.7 billion in claims
paying resources (unaudited).

     As of September 30, 1999, FSA's insured portfolio (unaudited) was
approximately $126 billion supported by approximately $2.4 billion in claims
paying resources (unaudited).
<PAGE>

     None of AMBAC, MBIA, FGIC and FSA or any associate thereof, has any
material business relationship, direct or indirect, with the Trust.

     AMBAC, MBIA, FGIC and FSA are subject to regulation by the department of
insurance in each state in which they are qualified to do business. Such
regulation, however, is not a guarantee that any of AMBAC, MBIA, FGIC or FSA
will be able to perform on its contractual insurance in the event a claim should
be made thereunder at some time in the future.

     The information relating to AMBAC, MBIA, FGIC and FSA set forth above,
including the financial information, has been furnished by such corporations.
Financial information with respect to AMBAC, MBIA, FGIC and FSA appears in
reports filed by AMBAC, MBIA, FGIC and FSA with insurance regulatory authorities
and is subject to audit and review by such authorities. No representation is
made herein as to the accuracy or adequacy of such information with respect to
AMBAC, MBIA, FGIC or FSA or as to the absence of material adverse changes in
such information subsequent to the date thereof.

     Obligation will be counted as a Moody's Eligible Asset to the extent it
     satisfies Moody's current guidelines.

               Notwithstanding the foregoing, an asset will not be considered a
     Moody's Eligible Asset if it is held in a margin account or if it is
     subject to any material lien, mortgage, pledge, security interest or
     security agreement of any kind, except for (i) Liens to secure payment for
     services rendered or cash advanced to the Corporation by the Adviser, the
     custodian of the Corporation's assets, the Auction Agent or any Broker-
     Dealers and (ii) any Lien by virtue of a repurchase agreement. In addition,
     an asset irrevocably deposited for the payment of any of the items set
     forth in clauses (i) A through F of the Preferred Shares Basic Maintenance
     Amount will not be considered Moody's Eligible Assets.

     determined by reference to the increase in the Maximum Marginal Tax Rate as
     follows: for increases of up to 5%, 292%; for
     increases greater than 5% and up to 10%, 313%; for

of determining the S&P Discount Factor applicable to any such Moody's-rated
California Municipal Obligation, such California Municipal Obligation will be
deemed to have an S&P rating which is one full rating category lower than its
Moody's rating); (iv) is not subject to a covered call or covered put option
written by the Corporation; (v) is not part of a private placement of California
Municipal Obligations; and (vi) is part of an issue of California Municipal
Obligations with an original issue size of at least $20 million or, if of an

  that California Municipal Obligations falling within the utility issue type
  category will be broken down into three sub-categories (as described below)
  and such California Municipal Obligations will be considered S&P Eligible

  include an electric issue), and (iii) irrigation, resource recovery, solid
  waste and other utilities, provided that California Municipal Obligations
  included in this sub-category (iii) must be rated by S&P in order to be
  included in S&P Eligible Assets.

     The Corporation may include Other Municipal Obligations as S&P Eligible

their Date of Original Issue; and such definitions shall be adjusted from time
to time and without further action by the Board of Directors to reflect changes
made thereto independently by Moody's, S&P or any Substitute Rating Agency if
each of Moody's, S&P and any Substitute Rating Agency has advised the
Corporation in writing (i) separately or collectively of such adjustments and
(ii) collectively that such adjustments will not adversely affect their then-
current ratings on the Preferred Shares. 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 and shall be payable commencing on the Initial
Dividend Payment Date with respect to each series of Preferred Shares. Following
the Initial Dividend Payment Date for each series of 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 than 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 California 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, California 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 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, 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 therein 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

                                     C-1-20
<PAGE>

     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 W28 Preferred Shares)
     or a 7-day Dividend Payment Period (in the case of the Series W7
     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 (if, prior to the close of business on the second
     Business Day preceding such 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, California 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, California
     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 California Clearing House (next-day) funds at the same
     time on the preceding Business Day, and any payment made after
     12:00 noon, California 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, California City, 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 W28 Preferred Shares or 7 in the case of Series W7
     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

                                     C-1-21
<PAGE>

     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 of
     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

                                     C-1-22
<PAGE>

     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 the 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 Dividend
     Period (in the case of Series W28 Preferred Shares) or a 7-day
     Dividend Period (in the case of Series W7 Preferred Shares)
     provided that if the then-current Dividend Period in the case of
     the Series W28 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 W28 Preferred Shares) or a
     7-day Dividend Period (in the case of Series W7 Preferred Shares)
     and the Corporation may not again give a Notice of Special
     Dividend Period for 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 W28 Preferred Shares) or a 7-day
     Dividend Period (in the case of Series W7 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

                                     C-1-23
<PAGE>

     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 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 such 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 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 and California income tax rate applicable to
individuals or corporations (taking into account the Federal income tax
deductibility of state taxes paid or incurred), whichever is greater, in effect
at the end of 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

                                     C-1-24
<PAGE>

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 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

                                     C-1-26
<PAGE>

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 as 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

                                     C-1-27
<PAGE>

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 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

                                     C-1-28
<PAGE>

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).

<PAGE>

               (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., California 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 will 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 a
Preferred Shares Basic Maintenance Report and a Certificate of Minimum Liquidity
in accordance with paragraph 7(b)

                                     C-1-30
<PAGE>

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 to 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 a 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., California 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

                                     C-1-31
<PAGE>

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 the
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 the 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
     following such Valuation Date. The Corporation shall, by such
     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 of 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

                                     C-1-32
<PAGE>

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 on 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
Basic 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 by 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

                                     C-1-33
<PAGE>

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.

     Maximum Applicable Rate for any Dividend Payment Period included
     in such Special Dividend Period will be the Applicable Percentage

     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

                    The Corporation will take all reasonable action necessary to
enable Moody's and S&P to provide a rating for both series of Preferred Shares.
If either Moody's or S&P shall not make such a

                                     C-1-34
<PAGE>

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 the 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.

          (vii)   "Minimum Applicable Rate," for any Dividend Payment
     Period included in a Special Dividend Period for which Bid

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

          (i)     on or prior to the Submission Deadline on each Auction Date:

     desires to continue to hold without regard to the Applicable Rate for the
     next succeeding Dividend Period;

     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:

<PAGE>

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

                              (B)  the aggregate number of Outstanding Preferred
          Shares that are the 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

                                     C-1-37
<PAGE>

          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.

               (c)  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" or 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

                                     C-1-38
<PAGE>

          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 Articles 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 Rates 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

                                     C-1-39
<PAGE>

                         (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 W28 Preferred Shares)
          or 7 days (in the case of Series W7 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 to the Winning Bid Rate or Spread; and

                                    C-1-40
<PAGE>

                         (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 in
          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 held by such Existing Holder 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

                                    C-1-41
<PAGE>

     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
     deter mine, 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.

                                    C-1-42
<PAGE>

               (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.

     ------

and approved by the stockholders of the Corporation at a special meeting of the

service related contract.

ITEM 33:  UNDERTAKINGS

(1)  Registrant undertakes to suspend the offering of its shares until it amends
its prospectus if (a) subsequent to the effective date of its Registration
Statement, the net assets value declines more than 10 percent from its net asset
value as of the effective date of the Registration Statement, or (b) the net
asset value increases to an amount greater than its net proceeds as stated in
the prospectus.

(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
<PAGE>

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.

        2008 Term Trust Inc.
800 Scudders Mill Road

Ladies and Gentlemen:

        We have acted as special Maryland counsel to The BlackRock California
Insured Municipal 2008 Term Trust Inc., a Maryland corporation (the
"Corporation"), in connection with the registration under the Securities Act of
1933, as amended (the "Act"), of 1,062 shares of the Corporation's Auction Rate
Municipal Preferred Stock, Series W7 (Liquidation Preference $25,000 per share)
of the Corporation (the "Shares") pursuant to the Corporation's registration
statement on Form N-2, as amended (the "Registration Statement"). The Shares
will be issued pursuant to the Articles Supplementary to be filed with the
Maryland State Department of Assessments and Taxation. In this capacity, we have
examined such corporate records, certificates and documents as we deemed
necessary for the purpose of this opinion, including the form of Articles
Supplementary of the Corporation filed as an Exhibit to the Registration
Statement.

        Based on our examination, we advise you that in our opinion the Shares
to be issued by the Corporation have been duly and validly authorized and,
assuming that the Articles Supplementary are duly filed with and accepted by the
Maryland State Department of Assessments and Taxation prior to the issuance of
the Shares, when issued upon the terms set forth in the Registration Statement
as filed with the Commission, the Shares will be legally issued, fully paid and
non-assessable.

Registration Statement. In giving our consent, we do not thereby admit that we

                                CODE OF ETHICS


I.    INTRODUCTION

      This Code of Ethics (the "Code") has been adopted by the Board of
[Directors/Trustees] of the BlackRock investment companies listed on Schedule 1
(each a "Fund") in compliance with Rule 17j-1 (the "Rule") under the Investment
Company Act of 1940, as amended (the "1940 Act"), to establish standards and
procedures necessary to ensure that personnel of the Fund, in connection with
their personal trading activities, comply with their ethical and legal
obligations with respect to the Fund and the anti-fraud provisions under the
Rule.

II.   STATEMENT OF GENERAL PRINCIPALS

      This Code is based on the principle that the officers, directors and
employees of the Fund owe a fiduciary duty to the shareholders of the Fund, to
conduct their personal securities transactions in a manner that does not
interfere with Fund portfolio transactions or otherwise take unfair advantage of
their relationship to the Fund.  Persons covered by this Code must adhere to
this general principle as well as comply with the Code's specific provisions to
avoid any actual or potential conflict of interest or any abuse of such person's
position of trust and responsibility and to prevent such persons from engaging
in conduct prohibited by the 1940 Act.

amended (the "1934 Act") in determining whether a person is subject to the
provisions of Section 16 of the 1934 Act and the rules promulgated thereunder.

      G.  "Investment Personnel" means:

          1.   portfolio managers and any other employees of the Fund or the
Advisor or of any company in a control relationship to the Fund or the Advisor

Fund or (iii) any option to purchase or sell, and any security convertible into
or exchangeable for a Security.

IV.   STANDARDS OF CONDUCT

<PAGE>

      D.  Any report required to be made pursuant to paragraphs A and B shall be
consid ered to be made if:

          1.   Such reporting person requests that each broker who effects
transactions for such reporting person provides to the Fund monthly account
information (in the form attached as Exhibit A).

          2.   In the event no reportable transactions occurred during the

such reports pursuant to the code of ethics of the Advisor.

      E.  Compliance Personnel appointed by the Fund and the Advisor shall

and B, no person shall be required to make a report:

          1.   With respect to transactions effected for any account over which
such person does not have any direct or indirect influence or control; or

          2.   If such person is not an "interested person" of the Fund within
the meaning of Section 2(a)(19) of the 1940 Act and would be required to make
such a report solely by reason of being a director of the Fund, except where
such director knew or, in the ordinary course of fulfilling his official duties
as a director of the Fund, should have known that during the 15-day period

VI.   PRIOR APPROVAL OF CERTAIN INVESTMENTS

<PAGE>

          2.   Compliance Personnel assigned by the Fund will review each

      B.  Compliance Personnel may refuse to grant clearance of a personal
transaction in such person's sole discretion without being required to specify
any reason for the refusal.

      C.  Generally, Compliance Personnel will consider the following factors in
making a pre-clearance determination:

          1.   whether the investment opportunity should be reserved for the
Fund and its shareholders; and

          2.   whether the opportunity is being offered to an individual by
virtue of such person's position with the Fund.

          Whether the Fund has the ability to invest in a particular security
(as a result of investment restrictions or otherwise) is not a basis for pre-
clearance.

      The administration of this Code shall be the responsibility of Compliance
Personnel of the Fund whose duties shall include:

      A.  Maintaining a list of all Access Persons who are under duty to make

portfolio transactions of the Fund and securities being considered for purchase
or sale by the Fund to determine whether a violation of this Code may have

Code, made within the past five years after the end of the fiscal year in which

more advantageous price paid or received by the offending person or any other
sanction which the Board shall determine to be reasonable and proper.

I.    ADOPTION OF CODE OF ETHICS

      This Code has been adopted by the Board of [Directors/Trustees] of the
Fund, including a majority of the [Directors/Trustees] who are not "interested

].

      Prior to adopting this Code, the Board reviewed and approved the code of
ethics adopted by the Fund's Advisor, including all procedures or provisions
related to the enforcement of this Code. The Board based its approval of this
Code and the code of ethics of the Advisor on (i) certifications from the Fund
and the Advisor that adequate procedures are in place to prevent violations of
the codes and (ii) a determination that such codes are adequate and contain
provisions reasonably necessary to ensure that personnel of the Fund and the
Advisor comply with the Rule and this Code.

                    EMPLOYEE INVESTMENT TRANSACTION POLICY
                    --------------------------------------

                            FOR BLACKROCK, INC. AND

                            ITS AFFILIATED COMPANIES


I.  PREAMBLE

     A.  General Principles

        This Employee Investment Transaction Policy (the "Policy") is based on
the principle that you, as an officer, director or other Advisory Employee of an
Advisor affiliated with BlackRock, Inc. ("BlackRock"), owe a fiduciary duty of
undivided loyalty to the registered investment companies, institutional
investment clients, personal trusts and estates, guardianships, employee benefit
trusts, and other Advisory Clients which that Advisor serves./1/ Accordingly,
you must avoid transactions, activities, and relationships that might interfere
or appear to interfere with making decisions in the best interests of those
Advisory Clients.

        At all times, you must observe the following general principles:

        1.      You must place the interests of Advisory Clients first. As a
                fiduciary you must scrupulously avoid serving your own personal
                interests ahead of the interests of Advisory Clients. You must
                adhere to this general fiduciary principle as well as
___________________

/1/     This Policy uses a number of capitalized terms, e.g., Advisor, Advisory
Client, Advisory Employee, Beneficial Ownership, Exempt Security, Fixed Income
Security, Fully Discretionary Account, Futures Contract, Immediate Family,
Investment Transaction, Personal Account, Portfolio Employee, Portfolio Manager,
Related Account, and Security. The first time a capitalized term is used, a
definition is stated in the text or in a footnote. The full definitions of these
capitalized terms are set forth in Appendix I. To understand your
responsibilities under the Policy, it is important that you review and
understand all of the definitions of capitalized terms in Appendix I. As
indicated in Appendix I:

        The term "Advisor" means any entity affiliated with BlackRock, whether
        now in existence or formed after the date hereof, that is registered as
        (i) an investment advisor under the Investment Advisers Act of 1940, as
        amended, or (ii) a broker-dealer under the Securities Exchange Act of
        1934, as amended, other than any such investment advisor or broker-
        dealer that has adopted its own employee investment transaction policy.

        The term "Advisory Client" means a registered investment company, an
        institutional investment client, a personal trust or estate, a
        guardianship, an employee benefit trust, or another client with which
        the Advisor by which you are employed or with which you are associated
        has an investment management, advisory or sub-advisory contract or
        relationship.

        The term "Advisory Employee" means an officer, director, or employee of
        an Advisor, or any other person identified as a "control person" on the
        Form ADV or the Form BD filed by the Advisor with the U.S. Securities
        and Exchange Commission, (1) who, in connection with his or her regular
        functions or duties, generates, participates in, or obtains information
        regarding that Advisor's purchase or sale of a Security by or on behalf
        of an Advisory Client; (2) whose regular functions or duties relate to
        the making of any recommendations with respect to such purchases or
        sales; (3) who obtains information or exercises influence concerning
        investment recommendations made to an Advisory Client of that Advisor;
        or (4) who has line oversight or management responsibilities over
        employees described in (1), (2) or (3), above.
<PAGE>

                comply with the Policy's specific provisions. Technical
                compliance with the Policy will not automatically insulate from
                scrutiny any Investment Transaction/2/ that indicates an abuse
                of your fiduciary duties or that creates an appearance of such
                abuse.

                Your fiduciary obligation applies not only to your personal
                Investment Transactions but also to actions taken on behalf of
                Advisory Clients. In particular, you may not cause an Advisory
                Client to take action, or not to take action, for your personal
                benefit rather than for the benefit of the Advisory Client. For
                example, you would violate this Policy if you caused an Advisory
                Client to purchase a Security you owned for the purpose of
                increasing the value of that Security. If you are a Portfolio
                Employee,/3/ you would also violate this Policy if you made a
                personal investment in a Security that might be an appropriate

___________________

/2/     For purposes of this Policy, the term "Investment Transaction" means any
transaction in a Security or Futures Contract in which you have, or by reason of
the transaction will acquire, a Beneficial Ownership interest.

        As a general matter, the term "Security" means any stock, note, bond,
debenture or other evidence of indebtedness (including any loan participation or
assignment), limited partnership interest or investment contract other than an
Exempt Security (as defined above). The term "Security" includes an option on a
Security, an index of Securities, a currency or a basket of currencies,
including such an option traded on the Chicago Board of Options Exchange or on
the New York, American, Pacific or Philadelphia Stock Exchanges as well as such
an option traded in the over-the-counter market. The term "Security" does not
include a physical commodity or a Futures Contract.

        The term "Futures Contract" includes (a) a futures contract and an
option on a futures contract traded on a U.S. or foreign board of trade, such as
the Chicago Board of Trade, the Chicago Mercantile Exchange, the New York
Mercantile Exchange, or the London International Financial Futures Exchange (a
"Publicly-Traded Futures Contract"), as well as (b) a forward contract, a
"swap", a "cap", a "collar", a "floor" and an over-the-counter option (other
than an option on a foreign currency, an option on a basket of currencies, an
option on a Security or an option on an index of Securities) (a "Privately-
Traded Futures Contract").

        As a general matter, you are considered to have a "Beneficial Ownership"
interest in a Security or Futures Contract if you have the opportunity, directly
or indirectly, to profit or share in any profit derived from a transaction in
that Security or Futures Contract. You are presumed to have a Beneficial
Ownership interest in any Security or Futures Contract held, individually or
jointly, by you and/or by a member of your Immediate Family (as defined below).
In addition, unless specifically excepted by the Compliance Officer based on a
showing that your interest or control is sufficiently attenuated to avoid the
possibility of a conflict, you will be considered to have a Beneficial Ownership
interest in a Security held by: (1) a joint account to which you are a party,
(2) a partnership in which you are a general partner, (3) a limited liability
company in which you are a manager-member, (4) a trust in which you or a member
of your Immediate Family has an interest or (5) an investment club in which you
are a member.

        See Appendix I for more complete definitions of the terms "Beneficial
Ownership," "Futures Contract," and "Security."

/3/     The term "Portfolio Employee" means a Portfolio Manager or an Advisory
Employee who provides information or advice to a Portfolio Manager, who helps
execute a Portfolio Manager's decisions, or who directly supervises a Portfolio
Manager. The term "Portfolio Manager" means any employee of an Advisor who has
the authority, whether sole or shared or only from time to time, to make
investment decisions or to direct trades affecting an Advisory Client.

                investment for an Advisory Client without first considering the
                Security as an investment for the Advisory Client.

        2.      You must conduct all of your personal Investment Transactions in
                full compliance with this Policy, the PNC Code of Ethics, and
                the other policies of PNC Bank Corp. ("PNC") (including the
                policies that prohibit insider trading or that restrict trading
                in PNC Securities). BlackRock encourages you and your family to
                develop personal investment programs. However, those investment
                programs must remain within boundaries reasonably necessary to
                insure that appropriate safeguards exist to protect the
                interests of our Advisory Clients and to avoid even the
                appearance of unfairness or impropriety. Doubtful situations
                should be resolved in favor of our Advisory Clients and against
                your personal Investment Transactions.

        3.      You must not take inappropriate advantage of your position. The
                receipt of investment opportunities, perquisites, gifts or
                gratuities from persons seeking to do business, directly or
                indirectly, with BlackRock, an affiliate, or an Advisory Client
                could call into question the independence of your business
                judgment. Doubtful situations should be resolved against your
                personal interests.

        B.      The General Scope Of The Policy's Application To Personal
                Investment Transactions

        Rule 17j-1 under the Investment Company Act of 1940, as amended,
requires reporting of all personal Investment Transactions in Securities (other
than certain "Exempt Securities") by Advisory Employees, whether or not they are
Securities that might be purchased or sold by or on behalf of an Advisory
Client. This Policy implements that reporting requirement.

        However, since a primary purpose of the Policy is to avoid conflicts of
interest arising from personal Investment Transactions in Securities and other
instruments that are held or might be acquired on behalf of Advisory Clients,
this Policy only places restrictions on personal Investment Transactions in such
investments. This Policy also requires reporting and restricts personal
Investment Transactions in certain Futures Contracts which, although they are
not Securities, are instruments that Advisors buy and sell for Advisory Clients.

        Although this Policy applies to all officers, directors and other
Advisory Employees of BlackRock, the Policy recognizes that Portfolio Managers,
and the other Portfolio Employees who provide them with advice and who execute
their decisions, occupy more sensitive positions than other Advisory Employees,
and that it is appropriate to subject their personal Investment Transactions to
greater restrictions.

        C.      The Organization Of This Policy

        The remainder of this Policy is divided into four main topics. Section
II concerns personal investment transactions. Section III describes restrictions
that apply to Advisory Employees who receive inside information or seek to serve
on a board of directors or similar governing body. Section IV outlines the
procedure for seeking case-by-case exemptions from the Policy's requirements.
Section V summarizes the methods for ensuring compliance under this Policy. In
addition, the following Appendices are also a part of this Policy:

I.      Definitions Of Capitalized Terms

IV.     Initial Report Of Accounts

V.      Request For Duplicate Broker Reports

VI.     Investment Transaction Prior Notification Form

VII.    Fully Discretionary Account Form

        D.      Questions

        Questions regarding this Policy should be addressed to the Compliance
Officer. If you have any question regarding the interpretation of this Policy or
its application to a potential Investment Transaction, you should consult the
Compliance Officer before you execute that transaction.

II.     PERSONAL INVESTMENT TRANSACTIONS

        A.      In General

        Subject to the limited exceptions described below, you are required to
report all Investment Transactions in Securities and Futures Contracts made by
you, a member of your Immediate Family, a trust or an investment club in which
you have an interest, or on behalf of any account in which you have an interest
or which you direct./4/ In addition, you must provide prior notification of
certain Investment Transactions in Securities and Futures Contracts that an
Advisor holds or may acquire on behalf of an Advisory Client. (The exercise of
an option is an Investment Transaction for purposes of these requirements.) The
details of these reporting and prior notification requirements are described
below.

        B.      Reporting Obligations

                1.  Use Of Broker-Dealers And Futures Commission Merchants

        You must use a registered broker-dealer or futures commission merchant
to engage in any purchase or sale of a publicly traded Security or Futures
Contract. This requirement also applies to any purchase or sale of a Security or
Futures Contract in which you have, or by reason of the Investment Transaction
will acquire, a Beneficial Ownership interest. Thus, as a general matter, any
Securities or Futures Contract transactions by members of your Immediate Family
will need to be made through a registered broker-dealer or futures commission
merchant.

        2.      Initial Report

        Soon after commencing employment or after any event that causes you to
become subject to this Policy, you must supply to the Compliance Officer copies
of the most recent statements for each and every Personal Account and Related
Account that holds or is likely to hold a

_________________

/4/     The term "Immediate Family" means any of the following persons who
reside in your household or who depend on you for basic living support: your
spouse, any child, stepchild, grandchild, parent, stepparent, grandparent,
sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-
law, or sister-in-law, including any adoptive relationships.

                                      -4-

<PAGE>

Security or Futures Contract in which you have a Beneficial Ownership interest,
as well as copies of confirmations for any and all transactions subsequent to
the effective dates of those statements./5/ These documents should be supplied
to the Compliance Officer by attaching them to the form attached hereto as
Appendix IV.

        On that same form you should supply the name of any registered broker-
dealer and/or futures commission merchant and the number for any Personal
Account and Related Account that holds or is likely to hold a Security or
Futures Contract in which you have a Beneficial Ownership interest for which you
cannot supply the most recent account statement. You must also certify, where
indicated on the form, that the contents of the form and the documents attached
thereto disclose all such Personal Accounts and Related Accounts.

        In addition, you must also supply, where indicated on the form, the
following information for each Security or Futures Contract in which you have a
Beneficial Ownership interest, to the extent that this information is not
available from the statements attached to the form:

                1.   A description of the Security or Futures Contract,
                     including its name or title;

                2.   The quantity (e.g., in terms of numbers of shares, units or
                     contracts) and value (in dollars) of the Security or
                     Futures Contract; and

                3.   The custodian of the Security or Futures Contract.

                3.   New Accounts

        Upon the opening of a new Personal Account or a Related Account that
holds or is likely to hold a Security or a Futures Contract in which you have a
Beneficial Ownership interest, you

_________________

/5/     The term "Personal Account" means the following accounts that hold or
are likely to hold a Security or Futures Contract in which you have a Beneficial
Ownership interest:

        .  any account in your individual name;
        .  any joint or tenant-in-common account in which you have an interest
           or are a participant;
        .  any account for which you act as trustee, executor, or custodian; and
        .  any account over which you have investment discretion or have the
           power (whether or not exercised) to direct the acquisition or
           disposition of Securities or Futures Contracts (other than an
           Advisory Client's account that you manage or over which you have
           investment discretion), including the accounts of any individual or
           entity that is managed or controlled directly or indirectly by or
           through you, such as the account of an investment club to which you
           belong. There is a presumption that you can control accounts held by
           members of your Immediate Family sharing the same household. This
           presumption may be rebutted only by convincing evidence.

        The term "Related Account" means any account, other than a Personal
Account, that holds a Security or Futures Contract in which you have a direct or
indirect Beneficial Ownership interest (other than an account over which you
have no investment discretion and cannot otherwise exercise control) and any
account (other than an Advisory Client's account) of any individual or entity to
whom you give advice or make recommendations with regard to the acquisition or
disposition of Securities or Futures Contracts (whether or not such advice is
acted upon).

                                      -5-

<PAGE>

must give written notice to the Compliance Officer of the name of the registered
broker-dealer or futures commission merchant for that account and the
identifying number for that Personal Account or Related Account.

                4.  Timely Reporting Of Investment Transactions

        You must cause each broker-dealer or futures commission merchant that
maintains a Personal Account or a Related Account that holds a Security or a
Futures Contract in which you have a Beneficial Ownership interest to provide to
the Compliance Officer, on a timely basis, duplicate copies of confirmations of
all transactions in that account and of periodic statements for that account
("Duplicate Broker Reports").  A form for that purpose is attached hereto as
Appendix V.

In addition, you must report to the Compliance Officer, on a timely basis, any
transaction in a Security or Futures Contract in which you have or acquired a
Beneficial Ownership interest that was made without the use of a registered
broker-dealer or futures commission merchant.

                5.  Related Accounts

        The reporting obligations described above also apply to any Related
Account (as defined in Appendix I) and to any Investment Transaction in a
Related Account.

        It is important that you recognize that the definitions of "Personal
Account," "Related Account" and "Beneficial Ownership" in Appendix I probably
will require you to provide, or to arrange for the broker-dealer or futures
commission merchant to furnish, copies of reports for any account used by or for
a member of your Immediate Family or a trust in which you or a member of your
Immediate Family has an interest, as well as for any other accounts in which you
may have the opportunity, directly or indirectly, to profit or share in the
profit derived from any Investment Transaction in that account, including the
account of any investment club to which you belong.

                6.  Exemptions From Reporting

        You need not report Investment Transactions in any account, including a
Fully Discretionary Account,/6/ over which neither you nor an Immediate Family
Member has or had any direct or indirect influence or control. For example,
Investment Transactions in the account of your spouse in an employee benefit
plan would not have to be reported if neither you nor your spouse has any
influence or control over those Investment Transactions.

        You also need not report Investment Transactions in Exempt Securities
nor need you furnish, or require a broker-dealer or futures commission merchant
to furnish, copies of

_________________

/6/     The term "Fully Discretionary Account" means a Personal Account or
Related Account managed or held by a broker-dealer, futures commission merchant,
investment advisor or trustee as to which neither you nor an Immediate Family
Member: (a) exercises any investment discretion; (b) suggests or receives notice
of transactions prior to their execution; and (c) you do not otherwise has any
direct or indirect influence or control. In addition, to qualify as a Fully
Discretionary Account, the individual broker, registered representative or
merchant responsible for that account must not be responsible for nor receive
advance notice of any purchase or sale of a Security or Futures Contract on
behalf of an Advisory Client. To qualify an account as a Fully Discretionary
Account, the Compliance Officer must receive and approve a written notice, in
the form attached hereto as Appendix VIII, that the account meets the foregoing
qualifications as a Fully Discretionary Account.


                                      -6-

<PAGE>

confirmations or periodic statements for accounts that hold only Exempt
Securities./7/ This includes accounts that only hold U.S. Government securities,
money market interests, or shares in registered open-end investment companies
(i.e., mutual funds). This exemption from reporting will end immediately,
however, at such time as there is an Investment Transaction in that account in a
Security that is not an Exempt Security.

        C.      Prohibited Or Restricted Investment Transactions

        1.      Initial Public Offerings

        As an Advisory Employee, you may not acquire Beneficial Ownership of any
Security in an initial public offering, except that, with the approval of the
Compliance Committee and the  General Counsel of BlackRock, you may acquire
Beneficial Ownership of a Security in an initial public offering directed or
sponsored by BlackRock.  For purposes of this Policy, an initial public offering
shall not include the purchase of a Security in an initial public offering by
(i) a savings bank to its depositors, (ii) a mutual insurance company to its
 -                                     --
policyholders, (iii) an issuer of debt securities (other than debt securities
                ---
convertible into common or preferred stock) or (iv) with respect to an Advisory
                                                --
Employee employed by BlackRock International, Ltd. a building society to its
depositors.

        2.      Private Placements

        If you are a Portfolio Employee, you may not acquire Beneficial
Ownership of any Security in a private placement, or subsequently sell that
interest, unless you have received the prior written approval of the Compliance
Officer and of any supervisor designated by the Compliance Officer. Approval
will not be given unless a determination is made that the investment opportunity
should not be reserved for one or more Advisory Clients, and that the
opportunity to invest has not been offered to you by virtue of your position
with an Advisor.

        If you have acquired Beneficial Ownership of Securities in a private
placement, you must disclose that investment to your supervisor when you play a
part in any consideration of any investment by an Advisory Client in the issuer
of the Securities, and any decision to make such an investment must be
independently reviewed by a Portfolio Manager who does not have a Beneficial
Ownership interest in any Securities of the issuer.

     D.  Investment Transactions Requiring Prior Notification

_________________

/7/     The term "Exempt Security" means any Security (as defined in Appendix I)
not included within the definition of Security in SEC Rule 17j-1(e)(5) under the
Investment Company Act of 1940, as amended, including:

        1.  A direct obligation of the Government of the United States;

        2.  Shares of registered open-end investment companies (i.e., mutual
            funds); and

        3.  High quality short-term debt instruments, including, but not limited
            to, bankers' acceptances, bank certificates of deposit, commercial
            paper and repurchase agreements.

See Appendix I for a more complete definition of "Exempt Security."


                                      -7-

<PAGE>

        You must give prior notification to the Compliance Officer of any
Investment Transaction in Securities or Futures Contracts in a Personal Account
or Related Account, or in which you otherwise have or will acquire a Beneficial
Ownership interest, unless that Investment Transaction, Security or Futures
Contract falls into one of the following categories that are identified as
"exempt from prior notification." The purpose of prior notification is to permit
the Compliance Officer and the Compliance Committee to take reasonable steps to
investigate whether that Investment Transaction is in accordance with this
Policy. Satisfaction of the prior notification requirement does not, however,
constitute approval or authorization of any Investment Transaction for which you
have given prior notification. As a result, the primary responsibility for
compliance with this Policy rests with you.

        1.      Prior Notification Procedure

        Prior notification must be given by completing and submitting to the
Compliance Officer a copy of the prior notification form attached hereto as
Appendix VII.  No Investment Transaction requiring prior notification may be
executed prior to notice by the Compliance Officer that the prior notification
process has been completed.  The time and date of that notice will be reflected
on the prior notification form.  Unless otherwise specified, an Investment
Transaction requiring prior notification must be placed and executed by the end
of trading in New York City or, in the case of Advisory Employees employed by
BlackRock International, Ltd., by the end of trading in the United Kingdom on
the day of notice from the Compliance Officer that the prior notification
process has been completed.  If a proposed Investment Transaction is not
executed (with the exception of a limit order) within the time specified, you
must repeat the prior notification process before executing the transaction.  A
notice from a Compliance Officer that the prior notification process has been
completed is no longer effective if you discover, prior to executing your
Investment Transaction, that the information on your prior notification form is
no longer accurate, or if the Compliance Officer revokes his or her notice for
any other reason.

        The Compliance Officer may undertake such investigation as he or she
considers necessary to investigate whether an Investment Transaction for which
prior notification has been sought complies with the terms of this Policy and is
consistent with the general principles described at the beginning of this
Policy.

        As part of that investigation, the Compliance Officer or a designee of
the Compliance Officer will determine whether there is a pending buy or sell
order in the same equity Security or Futures Contract, or a Related Security, on
behalf of an Advisory Client./8/ If such an order exists, the Compliance Officer
will not provide notice that the prior notification process has been completed
until the Advisory Client's order is executed or withdrawn.

        2.      Exemptions From Prior Notification

        Prior notification will not be required for the following Investment
Transactions, Securities and Futures Contracts.  They are exempt only from the
Policy's prior notification requirement, and, unless otherwise indicated, remain
subject to the Policy's other requirements, including its reporting
requirements.


_________________

/8/     The term "Related Security" means, as to any Security, any instrument
related in value to that Security, including, but not limited to, any option or
warrant to purchase or sell that Security, and any Security convertible into or
exchangeable for that Security.

                                      -8-

<PAGE>

                (a) Transactions Exempt From Prior Notification

  Prior notification is not required for any of the following Investment
Transactions:

     1.   Any Investment Transaction in a Fully Discretionary Account that has
          been approved as such by the Compliance Officer.

     2.   Purchases of Securities under dividend reinvestment plans.

     3.   Purchases of Securities by an exercise of rights issued to the holders
          of a class of Securities pro rata, to the extent those rights are
          issued with respect to Securities of which you have Beneficial
          Ownership.

     4.   Acquisitions or dispositions of Securities as the result of a stock
          dividend, stock split, reverse stock split, merger, consolidation,
          spin-off or other similar corporate distribution or reorganization
          applicable to all holders of a class of Securities of which you have
          Beneficial Ownership.

     5.   Purchases of common stock of PNC Bank Corp. under the Employee Stock
          Purchase Plan.

     6.   With respect to Advisory Employees who are employed by BlackRock
          International, Inc., automatic investments by direct debit into a
          personal equity plan (PEP), or similar type of plan in Exempt
          Securities if the pre-notification process was completed for the first
          such investment.

     7.   Investment Transactions made by a person who serves on the Board of
          Directors of an Advisor and is not involved with the Advisory
          operations of such Advisor nor engages in the type of activities
          described under (1) (2) or (3) under the term Advisory Employee as
          defined in Appendix I.


                (b) Securities Exempt From Prior Notification

  Prior notification is not required for an Investment Transaction in an Exempt
Security, as defined in Appendix I, e.g., U.S. Government securities, shares in
registered open-end investment companies (i.e., mutual funds) and "high quality
short-term debt instruments" (as defined in Appendix I).

                (c) Futures Contracts Exempt From Prior Notification

Prior notification is not required for an Investment Transaction in the
following Futures Contracts:

     1.   Currency futures.

     2.   U.S. Treasury futures.

     3.   Eurodollar futures.

     4.   Physical commodity futures (e.g., contracts for future delivery of
                                      ----
          grain, livestock, fiber or metals).

     5.   Futures contracts to acquire Fixed Income Securities issued by a U.S.
          Government agency, a foreign government, or an international or
          supranational agency.

                                      -9-
<PAGE>

     6.   Futures contracts on the Standard and Poor's 500 (S&P 500) or the Dow
          Jones Industrial Average stock indexes.

     7.   For Advisory Employees who are employed by BlackRock International,
          Ltd., futures contracts on the Financial Times Stock Exchange 100
          (FTSE) Index.

     E.  Ban On Short-Term Trading Profits

  You may not profit from the purchase and sale, or the sale and purchase,
within 60 calendar days, of the same Securities and/or Related Security.  Any
such short-term trade must be reversed or unwound, or if that is not practical,
the profits must be disgorged and distributed in a manner determined by the
Compliance Committee.

     This short-term trading ban does not apply to Investment Transactions in
Exempt Securities (as defined in Appendix I) or in Futures Contracts.  This ban
also does not apply to a purchase or sale in connection with a Transaction
Exempt From Prior Notification (as described above in Section II.D.2.(a)), a
transaction in a Fully Discretionary Account or a transaction exempt from the
"blackout" periods pursuant to Section II.F.2 below.

  You are considered to profit from a short-term trade if Securities of which
you have Beneficial Ownership (including Securities held by Immediate Family
members) are sold for more than their purchase price, even though the Securities
purchased and the Securities sold are held of record or beneficially by
different persons or entities.

     F.  Blackout Periods

  Your ability to engage in certain Investment Transactions may be prohibited or
restricted during the "blackout" periods described below:

          1.  Specific Blackout Periods

               a.   You may not purchase or sell a Security, a Related Security,
                    or Futures Contract at a time when you intend or know of
                    another's intention to purchase or sell that same Security,
                    a Related Security, or Futures Contract, on behalf of an
                    Advisory Client of any Advisor (the "Specific Knowledge
                    Blackout Period").

               b.   In addition, if you are a Portfolio Employee, you may not
                    purchase or sell a Security, a Related Security or a Futures
                    Contract which you are actively considering or which you
                    have actively considered and rejected for purchase or sale
                    for an Advisory Client within the previous 15 calendar days
                    (the "15-Day Blackout Period") unless the Compliance
                    Officer, after consultation with your supervisor, has
                    approved your Investment Transaction./9/


/9/ SEC Rule 17j-1 places restrictions on the purchase or sale of any "security
    held or to be acquired" by a registered investment company. Rule 17j-1(e)(6)
    defines a "security held or to be acquired" by a registered investment
    company as including any security which, within the most recent 15 days, "is
    being or has been considered by such company or its investment adviser for
    purchase by such company."

                                      -10-
<PAGE>

               c.   Finally, if you are a Portfolio Manager, you may not
                    purchase or sell a Security, a Related Security, or Futures
                    Contract within 7 calendar days before or after a
                    transaction in that Security, a Related Security, or Futures
                    Contract, by an Advisory Client for which you are
                    responsible (the "7-Day Blackout Period").

  For Portfolio Employees or Portfolio Managers, the Compliance Officer will not
give such notice until any applicable 15-Day Blackout Period or 7-Day Blackout
Period has expired or any required approvals or exemptions have been obtained.
An Investment Transaction that violates one of these Blackout restrictions must
be reversed or unwound, or if that is not practical, the profits must be
disgorged and distributed in a manner determined by the Compliance Committee.

      2.  Exemptions From Blackout Restrictions

  The foregoing blackout period restrictions do not apply to Investment
Transactions in:

     a.   Exempt Securities, as defined in Appendix I.

     b.   Securities of a company listed on the Standard & Poor's 100 (S & P
          100) Index.

     c.   A Futures Contract Exempt From Prior Notification under this Policy

III. INSIDE INFORMATION AND SERVICE AS A DIRECTOR

     A.  Inside Information

     As an employee of a subsidiary of PNC, you must comply with the PNC Insider
Trading Policy.  A copy of that policy is included in Section E of the PNC Code
of Ethics.  In addition, as an Advisory Employee, you must notify the General
Counsel of BlackRock if you receive or expect to receive material non-public
information about an entity that issues securities.  The General Counsel will
determine the restrictions, if any, that will apply to your communications and
activities while in possession of that information.  In general, those
restrictions will include:

          1.    An undertaking not to trade, either on your own behalf or on
                behalf of an Advisory Client, in the securities of the entity
                about which you have material non-public information.

          2.    An undertaking not to disclose material non-public information
                to other Advisory Employees.

          3.    An undertaking not to participate in discussions with or
                decisions by other Advisory Employees relating to the entity
                about which you have material non-public information.

                                      -11-
<PAGE>

The General Counsel, in cooperation with the Compliance Officer, will maintain a
"restricted list" of entities about which Advisory Employees may have material
non-public information.  This "restricted list" will be available to the
Compliance Officer when he or she conducts investigations or reviews related to
the Prior Notification Procedure described previously in Section II(D)(1) or the
Post-Trade Monitoring process described below in Section V(B)(3).

     B.  Service As A Director

     You may not serve on the board of directors or other governing board of any
entity unless you have received the prior written approval of the General
Counsel of PNC, to the extent such approval is required under the terms of the
PNC Code of Ethics, and the General Counsel of BlackRock.  If permitted to serve
on a governing board, an Advisory Employee will be isolated from those Advisory
Employees who make investment decisions regarding the securities of that entity,
through a "Chinese wall" or other procedures determined by the General Counsel
of BlackRock. In general, the "Chinese wall" or other procedures will include:

          1.    An undertaking not to trade or to cause a trade on behalf of an
                Advisory Client in the securities of the entity on whose board
                you serve.

          2.    An undertaking not to disclose material non-public information
                about that entity to other Advisory Employees.

          3.    An undertaking not to participate in discussions with or
                decisions by other Advisory Employees relating to the entity on
                whose board you serve.

Any entity on whose board an Advisory Employee serves will be included on the
"restricted list" referenced in subsection A, above.

IV.  EXEMPTIONS

  The Compliance Committee, in its discretion, may grant case-by-case exceptions
to any of the foregoing requirements, restrictions or prohibitions, except that
the Compliance Committee may not exempt any Investment Transaction in a Security
(other than an Exempt Security) or a Futures Contract from the Policy's
reporting requirements.  Exemptions from the Policy's prior notification
requirements and from the Policy's restrictions on acquisitions in initial
public offerings, short-term trading and trading during blackout periods will
require a determination by the Compliance Committee that the exempted
transaction does not involve a realistic possibility of violating the general
principles described at the beginning of this Policy.  An application for a
case-by-case exemption, in accordance with this paragraph, should be made in
writing to the Compliance Officer, who will promptly forward that written
request to the members of the Compliance Committee.

                                      -12-

V.  COMPLIANCE

     A.   Certifications

          1.  Upon Receipt Of This Policy

  Upon commencement of your employment or the effective date of this Policy,
whichever occurs later, you will be required to acknowledge receipt of your copy
of this Policy by completing and returning to the Compliance Officer a copy of
the form attached hereto as Appendix II.  By that acknowledgment, you will also
agree:

          1.   To read the Policy, to make a reasonable effort to understand its
               provisions, and to ask the Compliance Officer questions about
               those provisions you find confusing or difficult to understand.

          2.   To comply with the Policy, including its general principles, its
               reporting requirements, its prohibitions, its prior notification
               requirements, its short-term trading and blackout restrictions.

          3.   To advise the members of your Immediate Family about the
               existence of the Policy, its applicability to their personal
               Investment Transactions, and your responsibility to assure that
               their personal Investment Transactions comply with the Policy.

          4.   To cooperate fully with any investigation or inquiry by or on
               behalf of the Compliance Officer or the Compliance Committee to
               determine your compliance with the provisions of the Policy.

In addition, your acknowledgment will recognize that any failure to comply with
the Policy and to honor the commitments made by your acknowledgment may result
in disciplinary action, including dismissal.

          2.   Annual Certificate Of Compliance

  You are required to certify on an annual basis, on a copy of the form attached
hereto as Appendix III, that you have complied with each provision of your
initial acknowledgment (see above).  In particular, your annual certification
will require that you certify that you have read and that you understand the
Policy, that you recognize that you are subject to its provisions, that you
complied with the requirements of the Policy during the year just ended and that
you have disclosed, reported, or caused to be reported all Investment
Transactions required to be disclosed or reported pursuant to the requirements
of the Policy.

     B.   Supervisory Procedures

          1.  The Compliance Committee

  The Policy will be implemented, monitored and reviewed by the Compliance
Committee.  The initial members of the Compliance Committee will be appointed by
the management committee of BlackRock.  The Compliance Committee, by a simple
majority of its members, may appoint new members of the Committee, may replace
existing members of the Committee, and may fill vacancies on the Committee.
Among other responsibilities, the Compliance Committee will consider requests
for case-by-case exemptions (described above) and will conduct investigations
(described below) of any actual or suspected violations of the Policy.  The

                                      -13-
<PAGE>

Compliance Committee will determine what remedial actions, if any, should be
taken by an Advisor in response to a violation of the Policy.  The Compliance
Committee will also provide reports (described below) regarding significant
violations of the Policy and the procedures to implement the Policy.  The
Compliance Committee may recommend changes to those procedures or to the Policy
to the management of the Advisors.  Finally, the Compliance Committee will
designate one person to act as Compliance Officer for all Advisors.

  2.  The Compliance Officer

  The Compliance Officer designated by the Compliance Committee will be
responsible for the day-to-day administration of the Policy for all Advisors,
subject to the direction and control of the Compliance Committee.  Based on
information supplied by the management of each Advisor, the Compliance Officer
will forward a copy of the Policy to each Advisory Employee subject to the
Policy and will notify each such person of his or her designation as an Advisory
Employee, Portfolio Employee or Portfolio Manager.  The Compliance Officer will
also be responsible for administration of the reporting and prior notification
functions described in the Policy, and will maintain the reports required by
those functions.  In addition, the Compliance Officer will attempt to answer any
questions from an Advisory Employee regarding the interpretation or
administration of the Policy.  When necessary or desirable, the Compliance
Officer will consult with the Compliance Committee about such questions.  The
Compliance Officer may designate one or more Assistant Compliance Officers to
whom the Compliance Officer may delegate any of the duties described in this
paragraph or in the succeeding paragraph, and who shall be empowered to act on
the Compliance Officer's behalf when the Compliance Officer is absent or
unavailable.

  3.  Post-Trade Monitoring And Investigations

  The Compliance Officer will review the Duplicate Broker Reports and other
information supplied for each Advisory Employee so that the Compliance Officer
can detect and prevent potential violations of the Policy.  This information may
also be disclosed to the Advisor's auditors, attorneys and regulators.  If,
based on his or her review of information supplied for an Advisory Employee, or
based on other information, the Compliance Officer suspects that the Policy may
have been violated, the Compliance Officer will perform such investigations and
make such inquiries as he or she considers necessary.  You should expect that,
as a matter of course, the Compliance Officer will make inquiries regarding any
personal Investment Transaction in a Security or Futures Contract that occurs on
the same day as a transaction in the same Security or Futures Contract on behalf
of an Advisory Client.  If the Compliance Officer reaches a preliminary
conclusion that an Advisory Employee may have violated this Policy, the
Compliance Officer will report that preliminary conclusion in a timely manner to
the Compliance Committee and will furnish to the Committee all information that
relates to the Compliance Officer's preliminary conclusion.  The Compliance
Officer may also report his or her preliminary conclusion and the information
relating to that preliminary conclusion to the Advisor's auditors, attorneys and
regulators.

  Promptly after receiving the Compliance Officer's report of a possible
violation of the Policy, the Compliance Committee, with the aid and assistance
of the Compliance Officer, will conduct an appropriate investigation to
determine whether the Policy has been violated and will determine what remedial
action should be taken by the Advisor in response to any such violation(s).  For
purposes of these determinations, a majority of the Compliance Committee will
constitute a quorum and action taken by a simple majority of that quorum will
constitute action by the Committee.

                                      -14-
<PAGE>

  4.  Remedial Actions

  The remedial actions that may be recommended by the Compliance Committee may
include, but are not limited to, disgorgement of profits, imposition of a fine,
censure, demotion, suspension or dismissal.  As part of any sanction, e.g., for
violation of the Policy's restrictions on short-term trading or trading during
blackout periods, you may be required to reverse or unwind a transaction and to
forfeit any profit or to absorb any loss from the transaction.  If an Investment
Transaction may not be reversed or unwound, you may be required to disgorge any
profits associated with the transaction, which profits will be distributed in a
manner prescribed by the Compliance Committee in the exercise of its discretion.
Profits derived from Investment Transactions in violation of this Policy may not
be offset by any losses from Investment Transactions in violation of this
Policy. Finally, evidence suggesting violations of criminal laws will be
reported to the appropriate authorities, as required by applicable law.

  In determining what, if any, remedial action is appropriate in response to a
violation of the Policy, the Compliance Committee will consider, among other
factors, the gravity of your violation, the frequency of your violations,
whether any violation caused harm or the potential of harm to any Advisory
Client, whether you knew or should have known that your Investment Transaction
violated the Policy, whether you engaged in an Investment Transaction with a
view to making a profit on the anticipated market action of a transaction by an
Advisory Client, your efforts to cooperate with the Compliance Officer's
investigation, and your efforts to correct any conduct that led to a violation.
In rare instances, the Compliance Committee may find that, for equitable
reasons, no remedial action should be taken.

  5.  Reports Of Violations Requiring Significant Remedial Action

  In a timely manner, and not less frequently than annually, the Compliance
Committee will report to the management committee of BlackRock, and to the
directors or trustees of each investment company that is an Advisory Client, any
known Policy violation requiring significant remedial action (as defined below)
and the disposition of that violation.  For this purpose, a significant remedial
action means any action that has a significant financial effect on the violator.
Evidence suggesting violations of criminal laws will be reported to the
appropriate authorities, as required by applicable law.

  6.  Annual Reports

  The Compliance Committee will furnish an annual report to the management
committee of BlackRock, and to the directors or trustees of each investment
company that is an Advisory Client, that, at a minimum, will:

     1.   Summarize existing procedures and restrictions concerning personal
          investing by Advisory Employees and any changes in those procedures
          and restrictions that were made during the previous year;

     2.   Summarize any violations of the Policy that resulted in significant
          remedial action during the previous year; and

     3.   Describe any changes in existing procedures or restrictions that the
          Compliance Committee recommends based upon its experience under the
          Policy, evolving industry practices, or developments in applicable
          laws or regulations.

                                    APPENDIX I

                         Definitions Of Capitalized Terms

  The following definitions apply to the capitalized terms used in the Policy:

Advisor

  The term "Advisor" means any entity affiliated with BlackRock, whether now in
existence or formed after the date hereof, that is registered as (i) an
investment advisor under the Investment Advisers Act of 1940, as amended, or
(ii) a broker-dealer under the Securities Exchange Act of 1934, as amended,
other than any such investment advisor or broker-dealer that has adopted its own
employee investment transaction policy.

Advisory Client

  The term "Advisory Client" means a registered investment company, an
institutional investment client, a personal trust or estate, a guardianship, an
employee benefit trust, or another client with which the Advisor by which you
are employed or with which you are associated has an investment management,
advisory or sub-advisory contract or relationship.

Advisory Employee

  The term "Advisory Employee" means an officer, director, or employee of an
Advisor, or any other person identified as a "control person" on the Form ADV or
the Form BD filed by the Advisor with the U.S. Securities and Exchange
Commission, (1) who, in connection with his or her regular functions or duties,
generates, participates in, or obtains information regarding that Advisor's
purchase or sale of a Security by or on behalf of an Advisory Client; (2) whose
regular functions or duties relate to the making of any recommendations with
respect to such purchases or sales; or (3) who obtains information or exercises
influence concerning investment recommendations made to an Advisory Client of
that Advisor or who has line oversight or management responsibilities over
employees who obtain such information or who exercise such influence.

Beneficial Ownership

  As a general matter, you are considered to have a "Beneficial Ownership"
interest in a Security or Futures Contract if you have the opportunity, directly
or indirectly, to profit or share in any profit derived from a transaction in
that Security.  You are presumed to have a Beneficial Ownership interest in any
Security or Futures Contract held, individually or jointly, by you and/or by a
member of your Immediate Family (as defined below).  In addition, unless
specifically excepted by the Compliance Officer based on a showing that your
interest or control is sufficiently attenuated to avoid the possibility of a
conflict, you will be considered to have a Beneficial Ownership interest in a
Security or Futures Contract held by: (1) a joint account to which you are a
party, (2) a partnership in which you are a general partner, (3) a limited
liability company in which you are a manager-member, or (4) a trust in which you
or a member of your Immediate Family has a vested interest.  Although you may
have a Beneficial Ownership interest in a Security or Futures Contract held in a
Fully Discretionary Account (as defined below), the application of this Policy
to such a Security or Futures Contract may be modified by the special exemptions
provided for Fully Discretionary Accounts.

  As a technical matter, the term "Beneficial Ownership" for purposes of this
Policy will be interpreted in the same manner as it would be under SEC Rule 16a-
1(a)(2) in determining

                                      A-1

<PAGE>

whether a person has beneficial ownership of a security for purposes of Section
16 of the Securities Exchange Act of 1934 and the rules and regulations
thereunder.

      instrument" means any instrument having a maturity at issuance of less
      than 366 days and which is rated in one of the highest two rating
      categories by a Nationally Recognized Statistical Rating Organization, or
      which is unrated but is of comparable quality.

  4.  For Advisory Employees employed by BlackRock International, Ltd., shares
      of authorized unit trusts, open-ended investment companies (OEIC's) and
      direct obligations of the Government of the United Kingdom.

Fixed Income Securities

  For purposes of this Policy, the term "Fixed Income Securities" means fixed
income Securities issued by agencies or instrumentalities of, or unconditionally
guaranteed by, the Government of the United States, corporate debt Securities,
mortgage-backed and other asset-backed Securities, fixed income Securities
issued by state or local governments or the political subdivisions thereof,
structured notes and loan participations, foreign government debt Securities,
and debt Securities of international agencies or supranational agencies.  For
purposes

                                      A-2

<PAGE>

of this Policy, the term "Fixed Income Securities" will not be interpreted to
include U.S. Government Securities or any other Exempt Security (as defined
above).

Fully Discretionary Account

  The term "Fully Discretionary Account" means a Personal Account or Related
Account (as defined below) managed or held by a broker-dealer, futures
commission merchant, investment advisor or trustee as to which neither you nor
an Immediate Family Member (as defined below):  (a) exercises any investment
discretion; (b) suggests or receives notice of transactions prior to their
execution; and (c) otherwise has any direct or indirect influence or control.
In addition, to qualify as a Fully Discretionary Account, the individual broker,
registered representative or merchant responsible for that account must not be
responsible for nor receive advance notice of any purchase or sale of a Security
or Futures Contract on behalf of an Advisory Client.  To qualify an account as a
Fully Discretionary Account, the Compliance Officer must receive and approve a
written notice, in the form attached hereto as Appendix VIII, that the account
meets the foregoing qualifications as a Fully Discretionary Account.

Futures Contract

  The term "Futures Contract" includes (a) a futures contract and an option on a
futures contract traded on a U.S. or foreign board of trade, such as the Chicago

"Security") (a "Privately-Traded Futures Contract").  You should consult with
the Compliance Officer if you have any doubt about whether a particular
Investment Transaction you contemplate involves a Futures Contract.  For
purposes of this definition, a Publicly-Traded Futures Contract is defined by
its expiration month, i.e., a Publicly-Traded Futures Contract on a U.S.
Treasury Bond that expires in June is treated as a separate Publicly-Traded
Futures Contract, when compared to a Publicly-Traded Futures Contract on a U.S.
Treasury Bond that expires in July.

Immediate Family

  The term "Immediate Family" means any of the following persons who reside in
your household or who depend on you for basic living support:  your spouse, any
child, stepchild, grandchild, parent, stepparent, grandparent, sibling, mother-

in-law, including any adoptive relationships.

Investment Transaction

  For purposes of this Policy, the term "Investment Transaction" means any
transaction in a Security or Futures Contract in which you have, or by reason of
the transaction will acquire, a Beneficial Ownership interest.  The exercise of
an option to acquire a Security or Futures Contract is an Investment Transaction
in that Security or Futures Contract.

Personal Account

  The term "Personal Account" means the following accounts that hold or are

                                      A-3

<PAGE>

     .  any joint or tenant-in-common account in which you have an interest or
          are a participant;

     .  any account for which you act as trustee, executor, or custodian; and

        (whether or not exercised) to direct the acquisition or disposition of
        Securities or Futures Contracts (other than an Advisory Client's account
        that you manage or over which you have investment discretion), including
        the accounts of any individual or entity that is managed or controlled
        directly or indirectly by or through you. There is a presumption that
        you can control accounts held by members of your Immediate Family
        sharing the same household. This presumption may be rebutted only by
        convincing evidence.

Policy

  The term "Policy" means this Employee Investment Transaction Policy.

Portfolio Employee

  The term "Portfolio Employee" means a Portfolio Manager or an Advisory
Employee who provides information or advice to a Portfolio Manager, who helps
execute a Portfolio Manager's decisions, or who directly supervises a Portfolio
Manager.

Portfolio Manager

  The term "Portfolio Manager" means any employee of an Advisor who has the
authority, whether sole or shared or only from time to time, to make investment
decisions or to direct trades affecting an Advisory Client.

Related Account

  The term "Related Account" means any account, other than a Personal Account,
that holds a Security or Futures Contract in which you have a direct or indirect
Beneficial Ownership interest (other than an account over which you have no
investment discretion and cannot otherwise exercise control) and any account
(other than an Advisory Client's account) of any individual or entity to whom
you give advice or make recommendations with regard to the acquisition or
disposition of Securities or Futures Contracts (whether or not such advice is
acted upon).

Related Security

  The term "Related Security" means, as to any Security, any instrument related
in value to that Security, including, but not limited to, any option or warrant
to purchase or sell that Security, and any Security convertible into or
exchangeable for that Security.  For example, the purchase and exercise of an
option to acquire a Security is subject to the same restrictions that would
apply to the purchase of the Security itself.

Security

  As a general matter, the term "Security" means any stock, note, bond,
debenture or other evidence of indebtedness (including any loan participation or
assignment), limited partnership interest, or investment contract, other than an
Exempt Security (as defined above).  The term "Security" includes an option on a
Security, an index of Securities, a currency or a basket of

                                      A-4


<PAGE>

currencies, including such an option traded on the Chicago Board of Options
Exchange or on the New York, American, Pacific or Philadelphia Stock Exchanges
as well as such an option traded in the over-the-counter market. The term
"Security" does not include a physical commodity or a Futures Contract. The term
"Security" may include an interest in a limited liability company (LLC) or in a
private investment fund.

  As a technical matter, the term "Security" has the meaning set forth in
Section 2(a)(36) of the Investment Company Act of 1940, which defines a Security
to mean:

     Any note, stock, treasury stock, bond debenture, evidence of indebtedness,
     certificate of interest or participation in any profit-sharing agreement,
     collateral-trust certificate, preorganization certificate or subscription,
     transferable share, investment contract, voting-trust certificate,
     certificate of deposit for a security, fractional undivided interest in
     oil, gas, or other mineral rights, any put, call, straddle, option, or
     privilege on any security (including a certificate of deposit) or on any
     group or index of securities (including any interest therein or based on
     the value thereof), or any put, call, straddle, option, or privilege
     entered into on a national securities exchange relating to foreign
     currency, or, in general, any interest or instrument commonly known as a
     "security", or any certificate of interest or instrument commonly known as
     a "security", or any certificate of interest or participation in, temporary
     or interim certificate for, receipt for, guarantee of, warrant or right to

except that the term "Security" does not include any Security that is an Exempt
Security (as defined above), a Futures Contract (as defined above), or a
physical commodity (such as foreign exchange or a precious metal).
