                         BOULDER TOTAL RETURN FUND, INC.
            Articles Supplementary Creating and Fixing the Rights of
                     Taxable Auction Market Preferred Stock

      BOULDER TOTAL RETURN FUND, INC., a Maryland corporation having its
principal Maryland office in the City of Baltimore (the "Corporation"),
certifies to the State Department of Assessments and Taxation of Maryland that:

      FIRST: Pursuant to authority expressly vested in the Board of Directors of
the Corporation by Article IV of its Articles of Incorporation (which, as
hereafter restated or amended from time to time are, together with these
Articles Supplementary, herein called the "Articles"), the Board of Directors
has classified 1,000 shares of Preferred Stock, par value $.01 per share, as
shares of a series designated: Taxable Auction Market Preferred Stock ("AMPS"),
liquidation preference $100,000 per share plus an amount equal to dividends on
each share (whether or not earned or declared) accumulated and unpaid thereon.

      SECOND: The preferences, voting powers, restrictions, limitations as to
dividends, qualifications, and terms and conditions of redemption, of the shares
of such series of preferred stock are as follows:

                                     Part I

      1. Number of Shares; Ranking.

      (a) The number of authorized shares constituting the AMPS is 1,000. No
fractional shares of AMPS shall be issued.

      (b) Any shares of AMPS which at any time have been redeemed, purchased or
otherwise acquired by the Corporation shall, after such redemption, purchase or
acquisition, have the status of authorized but unissued shares of AMPS.

      (c) The shares of AMPS shall rank on a parity with shares of any other
series of Preferred Stock as to the payment of dividends and the distribution of
assets upon dissolution, liquidation or winding up of the affairs of the
Corporation.

      (d) The Corporation shall not reissue any shares of AMPS acquired by it
unless (i) on the Business Day on which such shares are reissued the Eligible
Asset Coverage is met giving effect to such reissuance and (ii) the Board of
Directors receives written confirmation from Moody's and S&P that such
reissuance would not impair the rating then assigned by Moody's and S&P to the
shares of AMPS.

      2. Dividends.

      (a) The Holders of shares of AMPS shall be entitled to receive, when, as
and if declared by the Board of Directors, out of funds legally available
therefor, cumulative cash dividends at the Applicable Rate per annum thereof,
determined as set forth in paragraph (c) of this Section 2, and


                                       1
<PAGE>

no more (except to the extent set forth in subparagraph (c)(i) of this Section
2) payable on the respective dates (each a "Dividend Payment Date") determined
as set forth in paragraph (b) of this Section 2. Dividends on shares of AMPS
shall accumulate at the Applicable Rate per annum from the Date of Original
Issue thereof, which is August 15, 2000.

      (b) (i) Dividends shall be payable, subject to subparagraph (b)(ii)(A) of
this Section 2, on shares of AMPS, on Wednesday, September 13, 2000, and on each
succeeding fourth Wednesday following such date, provided that if the
Corporation, subject to the conditions set forth in Section 4 of this Part I,
designates any Subsequent Rate Period as a Special Rate Period that consists of:

            (A) 56 Rate Period Days, dividends shall be payable, subject to
      subparagraph (b)(ii)(A) of this Section 2, on shares of AMPS on the eighth
      Wednesday after the first day of such Special Rate Period;

            (B) 91 Rate Period Days, dividends shall be payable, subject to
      subparagraph (b)(ii)(A) of this Section 2, on shares of AMPS on the
      thirteenth Wednesday after the first day of such Special Rate Period;

            (C) 182 Rate Period Days, dividends shall be payable, subject to
      subparagraph (b)(ii)(A) of this Section 2, on shares of AMPS on each of
      the thirteenth and twenty-sixth Wednesday after the first day of such
      Special Rate Period;

            (D) 365 or more Rate Period Days, dividends shall be payable,
      subject to subparagraph (b)(ii)(B) of this Section 2, on shares of AMPS,
      on the first day of the fourth month after the first day of such Special
      Rate Period and on the first day of each succeeding third month
      thereafter; provided, however, that if dividends for the last Dividend
      Period in any Special Rate Period would be payable as determined in this
      subparagraph (b)(i)(C) on a day that is not a Wednesday, then dividends
      for such last Dividend Period shall be payable instead on the first
      Wednesday preceding such day. After any Special Rate Period, dividends on
      such shares of AMPS shall be payable, subject to subparagraph (b)(ii)(A)
      of this Section 2, on each succeeding fourth Wednesday, subject in each
      case to the option of the Corporation to further designate from time to
      time any Subsequent Rate Period thereof as a Special Rate Period.

      (ii) (A) In the case of dividends that would be payable on a Wednesday, as
determined by subparagraph (b)(i) of this Section 2, including clause (A), (B)
or (C) of the proviso thereto, if:

                     (1) (x) the Securities Depository shall make available to
      its participants and members, in next-day funds in The City of New York,
      New York, on Dividend Payment Dates, the amount then due as dividends or
      shall make available to its participants and members, in funds immediately
      available in The City of New York, New York, on Dividend Payment Dates,
      such amount but shall not have so advised the Auction Agent of such
      availability, and (y) (I) such Wednesday is not a Business Day or (II) the
      day following such Wednesday is not a Business Day, then such dividends
      shall be payable on the first Business Day that falls prior to such
      Wednesday and is immediately followed by a Business Day; or


                                       2

                  (2) (x) the Securities Depository shall make available to its

      such availability, and (y) such Wednesday is not a Business Day, then such
      dividends shall be payable on the first Business Day that falls after such
      Wednesday.

            (B) In the case of dividends that would be payable on the first day
of a month, as determined by clause (D) of the proviso to subparagraph (b)(i) of
this Section 2, if:

                  (1) (x) the Securities Depository shall make available to its
      participants and members, in next-day funds in The City of New York, New
      York, on Dividend Payment Dates, the amount then due as dividends or shall
      make available to its participants and members, in funds immediately
      available in The City of New York, New York, on Dividend Payment Dates,
      such amount but shall not have so advised the Auction Agent of such
      availability, and (y) (I) such first day of the month is not a Business
      Day or (II) the day following such first day is not a Business Day, then
      dividends shall be payable on the first Business Day that falls after such
      first day of the month and is immediately followed by a Business Day; or

                   (2) (x) the Securities Depository shall make available to its
      participants and members, in funds immediately available in The City of
      New York, New York, on Dividend Payment Dates, the amount due as dividends
      on such Dividend Payment Dates and shall have advised the Auction Agent of
      such availability, and (y) such first day of the month is not a Business
      Day, then dividends shall be payable on the first Business Day after such
      first day of the month.

      (C) INTENTIONALLY OMITTED

      (iii) The Corporation shall pay or cause to be paid to the AMPS Paying
Agent not later than 12:00 Noon, New York City time, on the Business Day next
preceding each such Dividend Payment Date for shares of AMPS, an aggregate
amount of funds available on the next Business Day in The City of New York, New
York, equal to the dividends to be paid to all Holders on such Dividend Payment
Date. The Corporation may direct the AMPS Paying Agent to invest any such funds
in Short-Term Money Market Instruments, provided that the proceeds of any such
investment will be available in The City of New York, New York at the opening of
business on such Dividend Payment Date.

      (iv) All moneys paid to the AMPS Paying Agent for the payment of dividends
(or for the payment of any late charges pursuant to subparagraph (c)(i)(A) of
this Section 2) and any income or proceeds therefrom shall be held in trust for
the payment of such dividends (and any such late charges) by the AMPS Paying
Agent for the benefit of the Holders specified in subparagraph (b)(v) of this
Section 2. Any moneys paid to the AMPS Paying Agent in accordance with the
foregoing (and any income or proceeds therefrom) but not applied by the AMPS
Paying Agent to the payment of dividends (and any late charges) will, to the
extent permitted by law, be repaid to the


                                       3
<PAGE>

Corporation no later than the end of 12 months from the date on which such
moneys, income or proceeds were so to have been applied.

      (v) Each dividend on shares of AMPS shall be paid on the Dividend Payment
Date therefor to the Holders as their names appear on the stock books of the
Corporation on the Business Day next preceding such Dividend Payment Date.
Subject to paragraph (e) of this Section 2, 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 their names appear on the stock
books of the Corporation on such date, not exceeding 15 days preceding the
payment date thereof, as may be fixed by the Board of Directors.

      (c) (i) The dividend rate on shares of AMPS issued on August 15, 2000,
during the period from and after such Date of Original Issue to and including
the last day of the Initial Rate Period shall be equal to 6.57% per annum. For
each Subsequent Rate Period, the dividend rate on shares of AMPS shall be equal
to the rate per annum that results from an Auction for such shares on the
Auction Date next preceding such Subsequent Rate Period; provided, however, that
if an Auction for any Subsequent Rate Period is not held for any reason or the
shares of AMPS are no longer held in the form of a single global certificate by
a Securities Depository or if a Failure to Deposit has occurred that has not
been cured (in which cases an Auction shall not be held), then, subject to the
next succeeding proviso, the dividend rate on such shares for such Subsequent
Rate Period shall be the Maximum Rate on the Auction Date for such Subsequent
Rate Period; provided, further, however, that if:

            (A) any Failure to Deposit shall have occurred with respect to
      shares of AMPS during any Rate Period thereof (other than any Special Rate
      Period consisting of four or more Dividend Periods or any Rate Period
      succeeding any Special Rate Period consisting of four or more Dividend
      Periods during which a Failure to Deposit occurred that has not been
      cured), and, prior to 12:00 Noon, New York City time, on the third
      Business Day next succeeding the date on which such Failure to Deposit
      occurred, such Failure to Deposit shall not have been cured in accordance
      with the next succeeding sentence or the Corporation shall not have paid
      to the AMPS Paying Agent a late charge equal to the sum of:

                  (1) if such Failure to Deposit consisted of the failure to pay
            timely to the AMPS Paying Agent pursuant to subparagraph (c)(ii) of
            this Section 2 the full amount of dividends with respect to any
            Dividend Period on such shares, an amount computed by multiplying
            (x) 275% of the "AA" Composite Commercial Paper Rate for the Rate
            Period during which such Failure to Deposit occurs on the Dividend
            Payment Date for such Dividend Period by (y) a fraction, the
            numerator of which shall be the number of days for which such
            Failure to Deposit has not been cured in accordance with the next
            succeeding sentence (including the day such Failure to Deposit
            occurs and excluding the day such Failure of Deposit is cured) and
            the denominator of which shall be 360, and applying the rate
            obtained against the product of $100,000 and the number of
            outstanding shares of AMPS; and

                  (2) if such Failure to Deposit consisted of the failure to pay
            timely to the AMPS Paying Agent pursuant to paragraph (e) of Section
            3 of this Part I the cash redemption


                                       4
<PAGE>

            price of the shares of AMPS of such series, if any, for which Notice
            of Redemption has been given by the Corporation pursuant to
            paragraph (b) of Section 3 of this Part I, an amount computed by
            multiplying (x) 225% of the "AA" Composite Commercial Paper Rate for
            the Rate Period during which such Failure to Deposit occurs on the
            redemption date by (y) a fraction, the numerator of which shall be
            the number of days for which such Failure to Deposit is not cured in
            accordance with the next succeeding sentence (including the day such
            Failure to Deposit occurs and excluding the day such Failure to
            Deposit is cured) and the denominator of which shall be 360, and
            applying the rate obtained against the aggregate cash redemption
            price of the shares of AMPS to be redeemed; or

            (B) any Failure to Deposit shall have occurred with respect to
      shares of AMPS during a Special Rate Period thereof consisting of seven or
      more Dividend Periods, or during any Rate Period thereof succeeding any
      Special Rate Period consisting of seven or more Dividend Periods during
      which a Failure to Deposit occurred that has not been cured, and such
      Failure to Deposit shall not have been cured in accordance with the next
      succeeding sentence during such Special Rate Period or such Rate Period,
      or the Corporation shall not have paid to the AMPS Paying Agent a Late
      Charge calculated as set forth in subparagraph (c)(i)(A) of Section 2
      above (except that for this purpose, the "AA" Composite Commercial Paper
      Rate shall be the "AA" Composite Commercial Paper Rate applicable to a
      Rate Period (x) consisting of 148 or more Rate Period Days but fewer than
      182 Rate Period Days and (y) commencing on the date on which the Rate
      Period during which the Failure to Deposit occurred commenced),

then the dividend rate for shares of AMPS for each Subsequent Rate Period
thereof commencing after such failure to and including the Subsequent Rate
Period, if any, during which such Failure to Deposit is so cured shall be a rate
per annum equal to the Maximum Rate on the Auction Date for such Subsequent Rate
Period (but with the prevailing rating of such shares, for purposes of
determining such Maximum Rate, being deemed to be "Below 'baa3'") (the rate per
annum at which dividends are payable on shares of AMPS for any Rate Period for
such shares being herein referred to as the "Applicable Rate" for such shares).
A Failure to Deposit with respect to shares of AMPS shall have been cured (if
such Failure to Deposit is not solely due to the willful failure of the
Corporation to make required payments to the AMPS Paying Agent) with respect to
any Rate Period if, not later than 12:00 Noon, New York City time, on the fourth
Business Day preceding the Auction Date for the Rate Period subsequent to such
Rate Period the Corporation shall have paid to the AMPS Paying Agent (A) all
accumulated and unpaid dividends on the shares of AMPS and (B) without
duplication, the redemption price due and unpaid for the shares of AMPS, if any,
for which Notice of Redemption has been given by the Corporation pursuant to
paragraph (b) of Section 3 of this Part I.

            (ii) The amount of dividends per share payable on shares of AMPS on
any date on which dividends shall be payable on such shares shall be computed by
multiplying the respective Applicable Rate in effect for such Dividend Period or
Dividend Periods or part thereof for which dividends have not been paid by a
fraction, the numerator of which shall be the number of days in such Dividend
Period or Dividend Periods or part thereof and the denominator of which shall be
360, and applying the rate obtained against $100,000. Any dividend payment made
on shares of


                                       5
<PAGE>

AMPS shall be credited against the earliest accumulated but unpaid dividends due
with respect to such shares of AMPS.

      (d) INTENTIONALLY OMITTED

      (e) (i) Except as set forth in the next sentence, no dividends shall be
declared or paid or set apart for payment on the shares of any class or series
of stock ranking, as to the payment of dividends, on a parity with shares of
AMPS for any period unless full cumulative dividends have been or
contemporaneously are declared and paid on the shares of AMPS and any other
parity stock through the most recent respective Dividend Payment Date with
respect thereto. When dividends are not paid in full as aforesaid, upon the
shares of AMPS or any other class or series of stock ranking on a parity as to
the payment of dividends with shares of AMPS, all dividends declared upon shares
of AMPS and any other such class or series of stock ranking on a parity as to
the payment of dividends with shares of AMPS shall be declared pro rata so that
the amount of dividends declared per share on shares of AMPS and such other
class or series of stock shall in all cases bear to each other the same ratio
that accumulated dividends per share on the shares of AMPS and such other class
or series of stock bear to each other (for purposes of this sentence, the amount
of dividends declared per share shall be based on the Applicable Rate for such
shares for the Dividend Periods during which dividends were not paid in full).
Holders of shares of AMPS shall not be entitled to any dividend, whether payable
in cash, property or stock, in excess of full cumulative dividends, as herein
provided, on shares of AMPS. No interest, or sum of money in lieu of interest,
shall be payable in respect of any dividend payment or payments on shares of
AMPS which may be in arrears, and, except to the extent set forth in
subparagraph (c)(i) of this Section 2, no additional sum of money shall be
payable in respect of any such arrearage.

            (ii) For so long as any shares of AMPS are outstanding, the
Corporation shall not declare, pay or set apart for payment any dividend or
other distribution in respect of the Common Stock or any other stock of the
Corporation ranking junior to the AMPS as to dividends or upon liquidation
(except a dividend payable in shares of Common Stock or such shares ranking
junior to the AMPS), or call for redemption, redeem, purchase or otherwise
acquire for consideration any Common Stock or any other shares of the
Corporation ranking junior to the AMPS as to dividends or upon liquidation,
unless:

            (A) immediately thereafter, the 1940 Act Asset Coverage is met, the
      Eligible Asset Coverage is met and the Dividend Coverage is met;

            (B) full cumulative dividends on all shares of AMPS for all past
      Rate Periods have been paid or declared and a sum sufficient for the
      payment of such dividends set apart for payment; and

            (C) the Corporation has redeemed the full number of shares of AMPS
      required to be redeemed by any provision for mandatory redemption
      contained in these Articles Supplementary (the number of shares subject to
      mandatory redemption to be determined without regard to the requirement
      that redemptions be made out of legally available funds).

The Certificate of 1940 Act Asset Coverage, the Certificate of Eligible Asset
Coverage and the Certificate of Dividend Coverage dated as of the applicable
evaluation date shall reflect any such


                                       6
<PAGE>

transaction. An officer's certificate shall be filed with the records of the
Corporation maintained at its principal executive office evidencing that (B) has
been satisfied.

            (iii) INTENTIONALLY OMITTED

      3. Redemption. (a)(i) Subject to the next succeeding sentence, the shares
of AMPS may be redeemed, at the option of the Corporation, as a whole or from
time to time in part, on any Dividend Payment Date therefor, at a redemption
price per share equal to the sum of:

            (A) $100,000;

            (B) an amount equal to all dividends (whether or not earned or
      declared) accumulated thereon up to but not including the date fixed for
      redemption and unpaid; and

            (C) if redeemed during any Special Rate Period, the applicable
      redemption premium, if any, specified in the next succeeding sentence. The
      applicable redemption premium per share of AMPS during any Rate Period
      that is redeemed pursuant to this subparagraph (a)(i) shall be such
      amount, if any, as is specified by the Board of Directors in connection
      with the establishment of such Special Rate Period.

      (ii) The shares of AMPS may be redeemed, at the option of the Corporation,
as a whole but not in part, on any Dividend Payment Date, at a redemption price
per share equal to the sum of $100,000 plus an amount equal to all dividends
(whether or not earned or declared) accumulated thereon up to but not including
the date fixed for redemption and unpaid.

      (iii) (A) If the 1940 Act Asset Coverage is not met as of the 1940 Act
Asset Coverage Cure Date as shown in a Certificate of 1940 Act Asset Coverage
and the related Accountants' Certificate delivered by the Corporation to the
Common Stock Paying Agent by the close of business on such 1940 Act Asset
Coverage Cure Date, then the Corporation shall, by the close of business on such
1940 Act Asset Coverage Cure Date, (1) notify the AMPS Paying Agent of its
intention to redeem on the earliest practicable date following such 1940 Act
Asset Coverage Cure Date the number of shares of AMPS set forth below and (2)
give a Notice of Redemption (which shall specify a mandatory redemption date
that is not fewer than 3 days nor more than 33 days after the date of such
notice) with respect to the redemption of AMPS on such mandatory redemption
date. On such mandatory redemption date, the Corporation shall redeem, out of
funds legally available therefor, the number of shares of AMPS equal to the
minimum number of shares the redemption of which, if such redemption had
occurred immediately prior to the opening of business on such 1940 Act Asset
Coverage Cure Date, would have resulted in the 1940 Act Asset Coverage having
been met on such 1940 Act Asset Coverage Cure Date or, if the 1940 Act Asset
Coverage cannot be so restored, all of the shares of AMPS, at a redemption price
equal to $100,000 per share (without payment of any premium) plus an amount
equal to all dividends (whether or not earned or declared) accumulated thereon
up to but not including such mandatory redemption date and unpaid.

            (B) If the Eligible Asset Coverage is not met as of any Eligible
Asset Cure Date as shown in a Certificate of Eligible Asset Coverage and the
related Accountants' Certificate delivered by the Corporation to the AMPS Paying
Agent by the close of business on the second Business Day following such
Eligible Asset Cure Date, then the Corporation shall, by the close of business
no


                                       7
<PAGE>

later than the second Business Day following such Eligible Asset Cure Date, (1)
notify the AMPS Paying Agent of its intention to redeem on the earliest
practicable date following such Eligible Asset Cure Date the number of shares of
AMPS determined as provided below and (2) give a Notice of Redemption (which
shall specify a mandatory redemption date that is not fewer than 3 days nor more
than 33 days after the date of such notice) with respect to the redemption of
shares of AMPS on such mandatory redemption date. The Corporation shall redeem,
out of funds legally available therefor, the number of shares of AMPS equal to
the minimum number of shares the redemption of which, if such redemption had
occurred immediately prior to the opening of business on such Eligible Asset
Cure Date, would have resulted in the Eligible Asset Coverage having been met on
such Eligible Asset Cure Date or, if the Eligible Asset Coverage cannot be
restored, all of the shares of AMPS, at a redemption price equal to $100,000 per
share (without payment of any premium) plus an amount equal to all dividends
(whether or not earned or declared) accumulated thereon up to but not including
such mandatory redemption date and unpaid.

            (C) In the event of a redemption in part of the shares of AMPS
pursuant to this subparagraph (a)(iii), such redemption shall not be effected on
either of the two Business Days immediately preceding an Auction Date.

      (b) If the Corporation shall determine or be required to redeem shares of
AMPS pursuant to paragraph (a) of this Section 3, it shall mail a Notice of
Redemption with respect to such redemption by first class mail, postage prepaid,
to each Holder of the shares to be redeemed, at such Holder's address as the
same appears on the stock books of the Corporation on the record date
established by the Board of Directors. Such Notice of Redemption shall be so
mailed no less than 3 nor more than 33 days prior to the date fixed for
redemption. Each such Notice of Redemption shall state: (i) the redemption date;
(ii) the number of shares of AMPS to be redeemed; (iii) the CUSIP number of such
shares; (iv) the redemption price; (v) the place or places where the
certificate(s) for such shares (properly endorsed or assigned for transfer, if
the Board of Directors shall so require and the Notice of Redemption shall so
state) are to be surrendered for payment of the redemption price; (vi) that
dividends on the shares to be redeemed will cease to accumulate on such
redemption date; (vii) the provision or provisions of paragraph (a) of this
Section 3 under which such redemption is made; and (viii) if applicable, that
the Holders of the shares of AMPS being called for redemption will not be
entitled to participate, with respect to such shares, in an Auction held
subsequent to the date of such Notice of Redemption. If fewer than all shares of
AMPS held by any Holder are to be redeemed, the Notice of Redemption mailed to
such Holder shall also specify the number of shares to be redeemed from such
Holder.

      (c) Notwithstanding the other provisions of this Section 3, the
Corporation shall not redeem, purchase or otherwise acquire for consideration
shares of AMPS unless:

                  (i) INTENTIONALLY OMITTED;

                  (ii) all accumulated and unpaid dividends on all outstanding
      shares of AMPS for all applicable past Rate Periods shall have been or are
      contemporaneously paid or declared and a sum sufficient for the payment of
      such dividends set apart for payment; and

                  (iii) other than in the case of mandatory redemptions pursuant
      to paragraph (a)(iii) of this Section 3 only, the 1940 Act Asset Coverage
      and the Eligible Asset Coverage would


                                       8
<PAGE>

      be met on the date of such redemption, purchase or other acquisition after
      giving effect thereto and, on or prior to such date, the Corporation
      provides to the Common Stock Paying Agent a Certificate of 1940 Act Asset
      Coverage and to the AMPS Paying Agent a Certificate of Eligible Asset
      Coverage, each together with a confirming Accountants' Certificate,
      showing compliance with this clause (iii) of this paragraph (c);

provided, however, that the Corporation may, without regard to the limitation
contained in clause (ii) of this paragraph (c), but subject to the requirements
of the 1940 Act, redeem, purchase or otherwise acquire shares of AMPS (A) as a
whole, pursuant to a mandatory redemption, (B) as a whole, pursuant to an
optional redemption, or (C) pursuant to a purchase or exchange offer made on an
equal basis for all of the outstanding shares of AMPS pursuant to the 1940 Act.
In the event that shares of AMPS are acquired pursuant to an exchange offer, the
securities exchanged for the AMPS must have a rating from Moody's and S&P
equivalent to the then-current rating on the AMPS. In the event that fewer than
all of the outstanding shares of AMPS are to be redeemed pursuant to either an
optional redemption or a mandatory redemption, the shares to be redeemed shall
otherwise be selected by lot, or such other method as the Board of Directors
shall deem fair and equitable. An officer's certificate shall be filed with the
records of the Corporation maintained at its principal executive offices
evidencing that (ii) has been satisfied.

      (d) On or after the redemption date, each Holder of shares of AMPS that
were called for redemption shall surrender the certificate evidencing such
shares to the Corporation at the place designated in the Notice of Redemption
and shall then be entitled to receive the cash redemption price, without
interest; provided, however, that if and so long as all shares of AMPS are held
of record by a single person, such person shall not be required to surrender the
certificate representing such shares in connection with a partial redemption of
shares of AMPS. If less than all of the shares represented by the share
certificate are to be redeemed and the share certificate has been surrendered,
the Corporation shall issue a new share certificate for the shares not redeemed.

      (e) Not later than 12:00 Noon, New York City time, on the Business Day
immediately preceding the redemption date (or, in the case of a refunding of the
AMPS with other shares of Preferred Stock or debt, on the redemption date), the
Corporation shall irrevocably deposit with (or, in the case of a wire transfer,
shall irrevocably instruct its bank to transfer to) the AMPS Paying Agent
sufficient funds to pay the cash redemption price of the shares of AMPS to be
redeemed and shall give the AMPS Paying Agent irrevocable instructions to apply
such funds and, if applicable, the income and proceeds therefrom, to the payment
of the cash redemption price for such shares upon surrender of the certificate
therefor. The Corporation may direct the AMPS Paying Agent to invest any such
available funds in Short-Term Money Market Instruments, provided that the
proceeds of any such investment will be available in The City of New York, New
York, at the opening of business on such redemption date. All such funds (to the
extent necessary to pay the full amount of the redemption price) shall be held
in trust for the benefit of the Holders.

      (f) If the Corporation shall have given or caused to be given a Notice of
Redemption as aforesaid, shall have irrevocably deposited with the AMPS Paying
Agent a sum sufficient to pay the cash redemption price for the shares of AMPS
as to which such Notice of Redemption was given and shall have given the AMPS
Paying Agent irrevocable instructions and authority to pay the cash redemption
price to the Holders of such shares, then on the date of such deposit (or, if no
such deposit shall have been made, then on the date fixed for redemption, unless
the Corporation


                                       9
<PAGE>

shall have defaulted in making payment of the redemption price), all rights of
the Holders of such shares by reason of their ownership of such shares, except
their right to receive the redemption price thereof (but without interest),
shall terminate, and such shares shall no longer be deemed outstanding for any
purpose, including, without limitation, calculation of the Eligible Asset
Coverage and the Dividend Coverage and the right of the Holders of such shares
to vote on any matter or to participate in any subsequent Auction. The
Corporation shall be entitled to receive, from time to time, from the AMPS
Paying Agent the income, if any, derived from the investment of moneys and/or
other assets deposited with it (to the extent that such income is not required
to pay the cash redemption price of the shares to be redeemed), and the Holders
of shares to be redeemed shall have no claim to any such income. In case the
Holder of any shares called for redemption shall not claim the redemption price
for his shares within two years after the redemption date, the AMPS Paying Agent
shall, upon demand, pay over to the Corporation such amount remaining on deposit
and the AMPS Paying Agent shall thereupon be relieved of all responsibility to
the Holder with respect to such shares, and such Holder shall thereafter look
only to the Corporation for payment of the redemption price of such shares.

      (g) Except as set forth in this Section 3 with respect to redemptions and
subject to the provisions of paragraph (e) of Section 2 and paragraph (b) of
Section 1 of this Part I and paragraph (c) of this Section 3 and the 1940 Act,
nothing contained herein shall limit any legal right of the Corporation to
purchase or otherwise acquire any shares of AMPS outside of an Auction at any
price, whether higher or lower than the redemption price, in privately
negotiated transactions or in the over-the-counter market or otherwise.

      (h) Solely for the purpose of determining the number of shares of AMPS to
be stated in a Notice of Redemption as subject to a mandatory or optional
redemption, the amount of funds legally available for such redemption shall be
determined as of the date of such Notice of Redemption. Unless the Corporation
is redeeming shares of AMPS with another preferred issue or with debt, the
Corporation shall not give a Notice of Redemption with respect to an optional
redemption unless at the time of giving such notice the Corporation shall have
sufficient legally available funds in the form of cash or U.S. Treasury
Securities and Short-Term Money Market Instruments maturing in 30 days or less
to effect the redemption of all of the shares of AMPS to be redeemed pursuant to
such notice. To the extent that any redemption of which Notice of Redemption has
been given is not made by reason of the absence of legally available funds
therefor, such redemption shall be made as soon as practicable to the extent
such funds become available. Failure to redeem shares of AMPS shall be deemed to
exist at any time after the date specified for redemption in the Notice of
Redemption when the Corporation shall have failed, for any reason whatsoever, to
deposit in trust funds with the AMPS Paying Agent with respect to any shares for
which such Notice of Redemption has been given. Notwithstanding the fact that
the Corporation may not have redeemed shares of AMPS for which a Notice of
Redemption has been given, dividends may be declared and paid on shares of AMPS
and shall include those shares of AMPS for which a Notice of Redemption has been
given, subject to paragraph (f) above.

      (i) In the event that the Corporation shall have given a Notice of
Redemption with respect to any of the shares of AMPS and the sale of any
Eligible Asset with a Discount Factor of greater than 1.000 shall be necessary
to provide sufficient moneys to redeem all such shares on the redemption date,
the Corporation shall sell or otherwise liquidate such asset as soon as
reasonably practicable


                                       10
<PAGE>

following the date on which such Notice of Redemption is given and shall take
all reasonable steps to ensure that all such sales or other liquidations are
effected no later than 30 days after such date.

      (j) In effecting any redemption pursuant to this Section 3, the
Corporation shall use its reasonable best efforts to comply with all applicable
procedural conditions precedent to effecting such redemption under the 1940 Act
and Maryland law, but shall effect no redemption except in accordance with the
1940 Act and Maryland law.

      (k) In the case of any redemption pursuant to this Section 3, only whole
shares of AMPS shall be redeemed.

      4. Designation of Special Rate Periods (a) The Corporation, at its option,
may designate any succeeding Subsequent Rate Period as a Special Rate Period;
provided, however, that such designation shall be effective only if:

            (i) notice thereof shall have been given in accordance with
paragraphs (b), (c) and (d) of this Section 4;

            (ii) any Failure to Deposit that shall have occurred with respect to
shares of AMPS during any Rate Period shall have been cured in accordance with
the provisions of the third sentence of subparagraph (c)(i) of Section 2 of this
Part I;

            (iii) Sufficient Clearing Bids (as defined in Section 1 of Part II
hereof) shall have existed in the Auction held on the Auction Date immediately
preceding the first day of such proposed Special Rate Period;

            (iv) if any Notice of Redemption shall have been mailed by the
Corporation pursuant to paragraph (b) of Section 3 of this Part I with respect
to any shares of AMPS, the Redemption Price with respect to any such shares of
AMPS shall have been paid to the Holders of such shares or set apart for
payment; and

            (v) if Merrill Lynch, Pierce, Fenner and Smith, Inc., or its
successor shall have notified the Corporation in writing that it believes the
auction for the Special Rate Period will be successful;

            (vi) Moody's and S&P shall each have confirmed in writing to the
Corporation that such designation shall not adversely affect their respective
then-current ratings of the AMPS.

      (b) If the Corporation proposes to designate any succeeding Subsequent
Rate Period as a Special Rate Period pursuant to paragraph (a) of this Section
4, not less than 10 nor more than 30 days prior to the date the Corporation
proposes to designate as the first day of such Special Rate Period (which shall
be such day that would otherwise be the first day of a Minimum Rate Period),
notice shall be given to the persons that are then parties to Broker-Dealer
Agreements with the Corporation.


                                       11
<PAGE>

      (c) Each such notice shall state (A) that the Corporation may exercise its
option to designate a succeeding Subsequent Rate Period as a Special Rate
Period, specifying the first day thereof and (B) that the Corporation will by
11:00 A.M., New York City time, on the second Business Day next preceding such
date notify the Auction Agent of either (1) its determination, subject to
certain conditions, to exercise such option, in which case the Corporation shall
specify the Special Rate Period designated, whether the shares of AMPS will be
subject to optional redemption during such Special Rate Period and, if so, the
redemption premium, if any, required to be paid by the Corporation in connection
with any such redemption during such Special Rate Period, whether the Dividend
Rate during such Special Rate Period will be a stated rate or a spread over a
specified security or index of securities, or (2) its determination not to
exercise such option, and (C) the Maximum Rate in the event of a failed auction.

      (d) Not later than 11:00 A.M., New York City time, on the second Business
Day next preceding the first day of any proposed Special Rate Period as to which
notice has been given as set forth in paragraph (b) of this Section 4, the
Corporation shall deliver to the Auction Agent either:

            (i) a notice stating (A) that the Corporation has determined to
designate the next succeeding Rate Period as a Special Rate Period, specifying
the same and the first day thereof and other matters referred to in paragraph
(c) of this Section 4, (B) the Auction Date immediately prior to the first day
of such Special Rate Period, (C) that such Special Rate Period shall not
commence if (1) on such Auction Date Sufficient Clearing Bids shall not exist
unless all shares of AMPS are subject to Hold Orders or (2) a Failure to Deposit
shall have occurred prior to the first day of such Special Rate Period with
respect to shares of AMPS and (D) the scheduled Dividend Payment Dates during
such Special Rate Period; such notice to be accompanied by a Certificate of
Eligible Asset Coverage showing that, as of the third Business Day next
preceding such proposed Special Rate Period, Eligible Assets were at least equal
to Eligible Asset Coverage as of such Business Day (assuming for purposes of the
foregoing calculation that the Maximum Rate is the Maximum Rate on such Business
Day as if such Business Day were the Auction Date for the proposed Special Rate
Period) and written confirmation from Moody's and S&P that the designation of
such Special Rate Period will not adversely affect Moody's and S&P's
then-current rating of the AMPS; or

            (ii) a notice stating that the Corporation has determined not to
exercise its option to designate a Special Rate Period of AMPS and that the next
succeeding Rate Period shall be a Minimum Rate Period.

If the Corporation fails to deliver either such notice (and, in the case of the
notice described in clause (i) above, a Certificate of Eligible Asset Coverage
and confirmation from Moody's and S&P to the effect set forth in clause (i) with
respect to any designation of any proposed Special Rate Period to the Auction
Agent by 11:00 A.M., New York City time, on the second Business Day next
preceding the first day of such proposed Special Rate Period, the Corporation
shall be deemed to have delivered a notice to the Auction Agent with respect to
such Special Rate Period to the effect set forth in clause (ii) of this
subparagraph 4(d).

      5. Voting Rights (a) Except as otherwise provided in the Articles or as
otherwise required by law, each Holder of shares of AMPS shall be entitled to
one vote for each share of AMPS held on


                                       12
<PAGE>

each matter submitted to a vote of shareholders of the Corporation, and the
holders of outstanding shares of AMPS and shares of Common Stock shall vote
together as a single class.

      (b) At any meeting of the shareholders of the Corporation held for the
election of directors, the holders of Preferred Stock, including AMPS, shall be
entitled, voting as a single class to the exclusion of the holders of all other
securities and classes of capital stock of the Corporation, to elect two
directors of the Corporation. Subject to paragraph (c) of this Section 5, the
holders of Common Stock of the Corporation, voting as a separate class, shall
elect the balance of the directors.

      (c) 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,
including shares of AMPS, would constitute a majority of the Board of Directors
as so increased by such smallest number; and the holders of shares of Preferred
Stock, including AMPS, shall be entitled, voting as a single class 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 dividends (whether or not earned or declared, and
whether or not funds are then legally available in an amount sufficient
therefor) on the outstanding shares of AMPS 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 AMPS Paying Agent for the payment of such
dividends; or

            (ii) if at any time holders of any other shares of Preferred Stock
are entitled to elect a majority of the directors of the Corporation. Upon the
termination of a Voting Period, the voting rights described in paragraph (c) of
this Section 5 shall cease, subject always, however, to the revesting of such
voting rights in the holders of Preferred Stock, including AMPS, upon the
further occurrence of either of the events described in paragraph (c) of this
Section 5.

      (d) (i) As soon as practicable after the accrual of any right of the
holders of shares of Preferred Stock, including AMPS, to elect additional
directors as described in paragraph (c) of this Section 5, the Corporation shall
notify the AMPS Paying Agent and the AMPS Paying Agent shall 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 or more than 30 days after the
date of mailing of such notice. If the Corporation fails to send such notice to
the AMPS Paying Agent or if the AMPS Paying Agent does not call such a special
meeting, it may be called by any such holder 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 single
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
additional directors prescribed in paragraph (c) of this Section 5. At any such
meeting or adjournment thereof in the absence of a quorum, the holders present
in person or by proxy shall have the power to


                                       13
<PAGE>

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, whether such right is created by these Articles Supplementary, by
the other provisions of the Articles, by statute or otherwise, no Holder shall
be entitled to vote and no share of AMPS shall be deemed to be "outstanding" for
the purpose of voting or determining the number of shares required to constitute
a quorum if, prior to or concurrently with the time of determination of shares
entitled to vote or shares deemed outstanding for quorum purposes, as the case
may be, the redemption price for the redemption of such shares has been
deposited in trust with the AMPS Paying Agent for that purpose and the requisite
Notice of Redemption with respect to such shares has been given as provided in
Section 3 of this Part I. No share of AMPS held by the Corporation or any
Affiliate shall have any voting rights or be deemed to be outstanding for voting
or other purposes.

            (iii) Except as provided in the next succeeding sentence, the terms
of office of all persons who are directors of the Corporation at the time of a
special meeting of holders of Preferred Stock, including AMPS, to elect
directors shall continue, notwithstanding the election at such meeting by such
holders of the number of directors that they are entitled to elect, and the
persons so elected by such holders, together with the two incumbent directors
elected by such holders and the remaining incumbent directors elected by the
holders of the Common Stock shall constitute the duly elected directors of the
Corporation. If the election of additional directors by the holders of Preferred
Stock, including AMPS, would cause the number of directors to exceed 12, then
the terms of office of a number of directors elected by the holders of Common
Stock shall terminate at the time of the special meeting to elect such
additional directors such that the sum of the number of remaining directors and
the number of additional directors does not exceed 12 and the number of
additional directors and the two directors elected by the holders of Preferred
Stock, including AMPS, constitute a majority of the entire Board of Directors.

            (iv) Simultaneously with the termination of a Voting Period, the
terms of office of the additional directors elected by the holders of Preferred
Stock, including AMPS, pursuant to paragraph (c) of this Section 5 shall
terminate, the remaining directors shall constitute the directors of the
Corporation and the voting rights of such holders to elect additional directors
pursuant to paragraph (c) of this Section 5 shall cease, subject to the
provisions of the last sentence of paragraph (c) of this Section 5.

            (v) If the right of the holders of Preferred Stock, including AMPS,
to elect additional directors as described in paragraph (c) of this Section 5
accrues during the period commencing one month prior to the Corporation's fiscal
year end and ending at the end of the fourth month after the Corporation's
fiscal year end, the Corporation shall not be required to hold a separate
meeting pursuant to subparagraph (d)(i) of this Section 5 and may, instead, call
an annual meeting for such purpose if such meeting has not been held following
such fiscal year end. At any such annual meeting, such holders, voting as a
single class, shall be entitled to elect two directors pursuant to paragraph (b)
of this Section 5 and additional directors pursuant to paragraph (c) of this
Section 5. Upon expiration of the Voting Period, the term of office of the
additional directors elected pursuant to paragraph (c) of this Section 5 shall
expire.


                                       14

      (e)   (i) In addition to all rights of holders of Preferred Stock set
            forth in the Articles, so long as any shares of AMPS are
            outstanding, the Corporation shall not

            (A)   without the affirmative vote of at least 80% of the votes
                  entitled to be cast by holders of AMPS, authorize, create or
                  issue any class or series of stock ranking prior to or on a
                  parity with the AMPS with respect to the payment of dividends
                  or the distribution of assets upon dissolution, liquidation or
                  winding up of the affairs of the Corporation (other than
                  previously authorized and unissued shares of AMPS, including
                  any shares of AMPS purchased or redeemed by the Corporation),
                  or increase the authorized amount of AMPS or any other
                  preferred stock; or

            (B)   without the affirmative vote of at least a majority of the
                  votes entitled to be cast by Holders of AMPS or such higher
                  percentage as may be required under any other provision of the
                  Articles, amend, alter or repeal the provisions of the
                  Articles, including these Articles Supplementary, whether by
                  merger, consolidation or otherwise, so as to adversely affect
                  in any material respect any of the contract rights expressly
                  set forth in the Articles, including these Articles
                  Supplementary, of such shares of AMPS , or to alter, modify or
                  eliminate any of the rights, preferences or privileges of the
                  AMPS specifically set forth in these Articles, including these
                  Articles Supplementary, so as to adversely affect the AMPS.

The class votes of the shares of AMPS described in these Articles will in each
case be in addition to any required separate vote of the requisite percentage of
shares of Common Stock and AMPS, voting together as a single class, necessary to
authorize the action in question.

            (ii) The Board of Directors, without the vote or consent of the
Holders, may from time to time amend, alter or repeal any or all of the
definitions of the terms listed below, and any such amendment, alteration or
repeal will not be deemed to adversely affect the contract rights of shares of
AMPS or adversely affect the AMPS, provided the Board of Directors receives
written confirmation from Moody's and S&P that any such amendment, alteration or
repeal would not impair the ratings then assigned by Moody's and S&P to the
shares of AMPS:

<PAGE>

            (iii) To the extent permitted by applicable law, the Board of
      Directors, without the vote or consent of the Holders, may from time to
      time amend, alter or repeal any provision of the Articles Supplementary,
      if (A) such amendment, alteration or repeal is at the request of Moody's,
      S&P or other rating agency the Corporation seeks to rate the AMPS and (B)
      it is determined by the Board of Directors that such amendment, alteration
      or repeal will not adversely affect the contract rights of shares of AMPS
      or adversely affect the AMPS, which determination shall be supported by an
      opinion of the Corporation's counsel to such effect.

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

      (g) Unless a higher percentage is provided for in the Articles, the
affirmative vote of the Holders of a majority of the outstanding shares of AMPS,
voting as a separate class, shall be required to approve any plan of
reorganization (as such term is used in the 1940 Act) adversely affecting such
shares or any action requiring a vote of security holders of the Corporation
under Section 13(a) of the 1940 Act, including a change in the Corporation's
subclassification from that of a closed-end investment company to that of an
open-end investment company. In the event a vote of Holders 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 that such vote is to be taken and the nature of the action
with respect to which such vote is to be taken. The Corporation shall, in a
timely fashion after such vote is taken, notify Moody's of the result of such
vote.

      6. Liquidation Rights (a) Upon the dissolution, liquidation or winding up
of the affairs of the Corporation, whether voluntary or involuntary, the Holders
shall be entitled to receive and to be paid out of the assets of the Corporation
available for distribution to its shareholders after satisfying claims of
creditors but before any payment or distribution shall be made on the Common
Stock or on any other class of stock of the Corporation ranking junior to the
AMPS upon dissolution, liquidation or winding up, liquidating distributions per
share of $100,000 plus an amount equal to all dividends (whether or not earned
or declared) accumulated thereon up to but not including the date of such
distribution and unpaid.

      (b) Neither the sale, lease or exchange (for cash, stock, securities or
other consideration) of all or substantially all the property or business of the
Corporation, nor the merger or consolidation of the Corporation into or with any
other entity, nor the merger or consolidation of any other entity into or with
the Corporation, nor any share exchange between the Corporation and any other
entity shall be deemed to be a dissolution, liquidation or winding up, whether
voluntary or involuntary, for the purpose of this Section 6.

      (c) After payment to the Holders of the full preferential amounts provided
in this Section 6, the Holders as such shall have no right or claim to any of
the remaining assets of the Corporation.


                                       16
<PAGE>

      (d) In the event the assets of the Corporation available for distribution
to the Holders upon any dissolution, liquidation or winding up of the affairs of
the Corporation, whether voluntary or involuntary, shall be insufficient to pay
in full all amounts to which such Holders are entitled pursuant to paragraph (a)
of this Section 6, no such distribution shall be made on account of any shares
of any other class or series of Preferred Stock ranking on a parity with the
shares of AMPS with respect to the distribution of assets upon such dissolution,
liquidation or winding up unless proportionate distributive amounts shall be
paid on account of the shares of AMPS, ratably, in proportion to the full
distributable amounts to which such Holders and the holders of all such parity
shares are respectively entitled upon such dissolution, liquidation or winding
up.

      (e) Subject to the rights of holders of shares of any series or class or
classes of stock ranking on a parity with the shares of AMPS with respect to the
distribution of assets upon dissolution, liquidation or winding up of the
affairs of the Corporation, after payment shall have been made in full to the
Holders as provided in paragraph (a) of this Section 6, but not prior thereto,
any other series or class or classes of stock ranking junior to the shares of
AMPS with respect to the distribution of assets upon dissolution, liquidation or
winding up of the affairs of the Corporation shall, subject to the respective

all assets remaining to be paid or distributed, and the Holders shall not be
entitled to share therein.

      7. 1940 Act Asset Coverage and Eligible Asset Coverage (a)(i) The
Corporation shall determine whether the 1940 Act Asset Coverage is met as of
each 1940 Act Asset Coverage Evaluation Date. The calculation of the asset
coverage for the AMPS on that date in accordance with the 1940 Act and whether
the 1940 Act Asset Coverage is met shall be set forth in a certificate (a
"Certificate of 1940 Act Asset Coverage") dated as of such 1940 Act Asset
Coverage Evaluation Date. In addition, as of each Eligible Asset Evaluation
Date, the Corporation shall determine:

            (A) the Coverage Value of each Eligible Asset owned by the
            Corporation on that date;

            (B) the Net Coverage Value of all such Eligible Assets;

            (C) the Eligible Asset Coverage Amount with respect to such Eligible
            Asset Evaluation Date; and

            (D) whether the Eligible Asset Coverage is met as of such date.

The calculation of the Coverage Value of each Eligible Asset, the Net Coverage
Value of all such Eligible Assets, the Eligible Asset Coverage Amount and
whether the Eligible Asset Coverage is met shall be set forth in a certificate
(a "Certificate of Eligible Asset Coverage") dated as of such Eligible Asset
Evaluation Date. As of each Dividend Coverage Evaluation Date, the Corporation
shall determine:

The Corporation shall cause the Certificate of 1940 Act Asset Coverage to be
delivered to the Common Stock Paying Agent not later than the close of business
on the third Business Day after the related 1940 Act Asset Coverage Evaluation
Date. The Corporation shall cause the Certificate


                                       17
<PAGE>

of Eligible Asset Coverage to be delivered to the AMPS Paying Agent not later
than the close of business on the third Business Day after the related
evaluation date. In addition, the Corporation shall cause the Certificate of
Eligible Asset Coverage to be delivered to Moody's quarterly. In the event that
the Eligible Asset Coverage is not met or is not met and is subsequently cured,
the Corporation shall cause the Certificate of Eligible Asset Coverage to be
delivered to Moody's not later than the close of business on the third Business
Day following such date of failure and/or on the second Business Day following
such date of cure.

            (ii) In the event that a Certificate of 1940 Act Asset Coverage or a
Certificate of Eligible Asset Coverage is not delivered to the Common Stock
Paying Agent or the AMPS Paying Agent, as the case may be, when required, the
1940 Act Asset Coverage or the Eligible Asset Coverage, as the case may be, will
be deemed not to have been met as of the related evaluation date.

      (b) With respect to (i) the Certificate of 1940 Act Asset Coverage
relating to any 1940 Act Asset Coverage Cure Date, and (ii) the Certificate of
Eligible Asset Coverage (A) as of August 11, 2000, (B) relating to the last
Eligible Asset Evaluation Date in each fiscal quarter and relating to one other
Eligible Asset Evaluation Date during each fiscal year as selected by the
Independent Accountants, and (C) relating to any Eligible Asset Cure Date, the
Corporation shall obtain from the Independent Accountants a written
communication confirming that:

                  (1) with respect to the 1940 Act Asset Coverage, (a) the
      calculations set forth in the related Certificate of 1940 Act Asset
      Coverage are mathematically accurate and (b) the Independent Accountants
      have traced the prices used by the Corporation in valuing the
      Corporation's portfolio investments to the prices provided to the
      Corporation by the Corporation's administrator or other appropriate
      service provider for such purpose and verified that such information
      agrees; and

                  (2) with respect to the Eligible Asset Coverage, (a) the
      calculations set forth in the related Certificate of Eligible Asset
      Coverage are mathematically accurate, (b) the method used by the
      Corporation in determining whether the Eligible Asset Coverage is met is
      in accordance with the applicable requirements of these Articles
      Supplementary, (c) the Independent Accountants have traced the prices used
      by the Corporation in the determination of Market Values of the Eligible
      Assets to the prices provided to the Corporation by the Corporation's
      administrator or other appropriate service provider for purposes of such
      determination and verified that such information agrees, (d) the
      Independent Accountants have calculated the liabilities and related
      assumed assets arising in connection with Section 8(b) of Part I, (e) the
      Corporation's positions in futures and options at such Eligible Asset
      Evaluation Date were in accordance with the provisions of Section 8(b) of
      Part I and (f) the assets listed as Eligible Assets in the related
      certificate conform to the descriptions of Eligible Assets set forth in
      these Articles (such a written communication being referred to herein as
      an "Accountants' Certificate").

The Corporation shall cause each Accountants' Certificate relating to any 1940
Act Asset Coverage Cure Date to be delivered, together with the related
Certificate of 1940 Act Asset Coverage, to the Common Stock Paying Agent by the
close of business on such 1940 Act Asset Coverage Cure Date. The Corporation
shall cause each Accountants' Certificate relating to the last Eligible Asset


                                       18
<PAGE>

Evaluation Date of each fiscal quarter and such other one Eligible Asset
Evaluation Date per fiscal year as selected by the Independent Accountants to be
delivered to the AMPS Paying Agent not later than the close of business on the
seventh Business Day following the last day of the related fiscal quarter (such
seventh Business Day being referred to herein as a "Confirmation Date") and
shall cause each Accountants' Certificate relating to any Eligible Asset Cure
Date to be delivered to the AMPS Paying Agent by the close of business on the
second Business Day following such Eligible Asset Cure Date. The Corporation
shall cause each Accountants' Certificate delivered to the Common Stock Paying
Agent or the AMPS Paying Agent, as the case may be, to be contemporaneously
delivered to Moody's. In the event of any difference between the Corporation's
calculations as shown on a Certificate of 1940 Act Asset Coverage or a
Certificate of Eligible Asset Coverage and the Independent Accountants'
calculations as shown on an Accountants' Certificate, such calculations of the
Independent Accountants shall control. If the Corporation shall designate a
Special Rate Period pursuant to Section 4 of this Part I, the Corporation shall
provide for an Accountants' Certificate relating to a Certificate of Eligible
Asset Coverage to be furnished to the AMPS Paying Agent at such additional times
as may be necessary to provide for such confirmations to be furnished at least
as frequently as provided prior to such alteration or as frequently as may be
necessary to maintain the then-current rating by Moody's of the shares of AMPS.

      (c) If the 1940 Act Asset Coverage is not met as of any 1940 Act Asset
Coverage Evaluation Date as shown in a Certificate of 1940 Act Asset Coverage
delivered to the Common Stock Paying Agent by the close of business on the third
Business Day after such 1940 Act Asset Coverage Evaluation Date, then the
Corporation shall (if and to the extent necessary to enable it to meet the
requirements of paragraph (d) of this Section 7):

            (i) by the close of business on the 1940 Act Asset Coverage Cure
Date relating to such 1940 Act Asset Coverage Evaluation Date, if the
Corporation shall have funds legally available for the purchase of shares of
AMPS, purchase such shares outside of an Auction in order that the 1940 Act
Asset Coverage is met as of such 1940 Act Asset Coverage Cure Date; and/or

            (ii) by the close of business on the applicable 1940 Act Asset
Coverage Cure Date, notify the AMPS Paying Agent of its intention to redeem, and
give a Notice of Redemption as described in these Articles Supplementary with
respect to the redemption of, shares of AMPS.

      (d) If the 1940 Act Asset Coverage is not met as of any 1940 Act Asset
Coverage Evaluation Date as shown in a Certificate of 1940 Act Asset Coverage,
then the Corporation shall, by the close of business on the applicable 1940 Act
Asset Coverage Cure Date, deliver to the Common Stock Paying Agent a Certificate
of 1940 Act Asset Coverage together with an Accountants' Certificate showing
that the 1940 Act Asset Coverage is met (or, if clause (ii) of paragraph (c) of
this Section 7 is applicable, would have been met) as of such 1940 Act Asset
Coverage Cure Date after giving effect to (A) any purchase of the shares of AMPS
outside of an Auction pursuant to clause (i) of paragraph (c) of this Section 7
and/or (B) any redemption of the shares of AMPS pursuant to the Notice of
Redemption contemplated by such clause (ii) (as if such redemption had occurred
immediately prior to the opening of business on such 1940 Act Asset Coverage
Cure Date).


                                       19

      (e) If (i) the Eligible Asset Coverage is not met as of any Eligible Asset
Evaluation Date as shown in a Certificate of Eligible Asset Coverage delivered
to the AMPS Paying Agent by the close of business on the third Business Day
after such Eligible Asset Evaluation Date or (ii) the Corporation is required to
deliver to the AMPS Paying Agent by the close of business on a Confirmation Date
an Accountants' Certificate confirming the Certificate of Eligible Asset
Coverage with respect to such Eligible Asset Evaluation Date, and the
Corporation fails timely to deliver such Accountants' Certificate, then the
Corporation shall (if and to the extent necessary to enable it to meet the
requirements of paragraph (f) of this Section 7):

           (A) by the close of business on the Eligible Asset Cure Date relating
      to such Eligible Asset Evaluation Date or Confirmation Date, as the case
      may be, purchase or otherwise acquire additional Eligible Assets or, if
      the Corporation shall have funds legally available for the purchase of
      shares of AMPS, purchase such shares outside of an Auction, or both, in
      order that the Eligible Asset Coverage is met as of such Eligible Asset
      Cure Date; and/or

            (B) by the close of business on the second Business Day after the
applicable Eligible Asset Cure Date, notify the AMPS Paying Agent of its
intention to redeem, and give a Notice of Redemption with respect to the
redemption of, shares of AMPS as described herein.

      (f) If the Eligible Asset Coverage is not met as of any Eligible Asset
Evaluation Date as shown in a Certificate of Eligible Asset Coverage or if an
Accountants' Certificate confirming a Certificate of Eligible Asset Coverage is
not timely delivered as contemplated by subclause (i) or subclause (ii) of
paragraph (e) of this Section 7, then the Corporation shall, by the close of
business on the second Business Day following the applicable Eligible Asset Cure
Date, deliver to the AMPS Paying Agent a Certificate of Eligible Asset Coverage
together with an Accountants' Certificate showing that the Eligible Asset
Coverage is met (or, if subclause (B) of such paragraph (e) is applicable, would
have been met) as of such Eligible Asset Cure Date after giving effect to:

            (i) any purchase or other acquisition of Eligible Assets or any
purchase of the shares of AMPS outside of an Auction pursuant to clause (A) of
paragraph (e) of this Section 7; and/or

            (ii) any redemption of the shares of AMPS pursuant to the Notice of
Redemption contemplated by clause (B) of such paragraph (e) (as if such
redemption had occurred immediately prior to the opening of business on such
Eligible Asset Cure Date).

      (g) INTENTIONALLY OMITTED

      (h) For purposes of determining whether the 1940 Act Asset Coverage is met
or the Eligible Asset Coverage is met, no share of the AMPS shall be deemed to
be "outstanding" for purposes of any computation if, prior to or concurrently
with such determination, (i) the requisite funds for the redemption of such
share shall have been deposited in trust with the AMPS Paying Agent for that
purpose and the requisite Notice of Redemption shall have been given or (ii)
such share shall have been redeemed, purchased or otherwise acquired by the
Corporation. In the case of clause (i) of this paragraph (h), the funds
deposited with the AMPS Paying Agent (to the extent necessary to pay the full
redemption price for such shares) shall not be included in determining whether
the 1940 Act Asset Coverage or the Eligible Asset Coverage are met.

      8. Certain Other Restrictions (a) For so long as any shares of AMPS are
outstanding and Moody's is rating such shares, the Corporation will not, unless
it has received written confirmation from Moody's that any such action would not
impair the rating then assigned by Moody's to shares of AMPS:

            (i) enter into options and futures transactions except as set forth
in paragraph (b) of this Section 8;

            (ii) make short sales of securities unless at all times when a short
position is open, the Corporation owns an equal or greater amount of such
securities or owns preferred stock, debt or warrants convertible or exchangeable
into an equal or greater number of the shares of common stocks sold short;

            (iii) overdraw any bank account (except as may be necessary for the
clearance of security transactions); or

            (iv) borrow money or issue senior securities (as defined in the 1940

      (b) For so long as the shares of AMPS are rated by Moody's, the
Corporation (i) may buy call or put option contracts on securities, (ii) may
write only covered call options on securities, (iii) may write put options on
securities, (iv) may only sell futures contracts as a bona fide hedge of assets
held by the Corporation, (v) may only engage in futures transactions on an
exchange where the exchange or its clearinghouse takes the opposite side of the
transaction, (vi) may buy call or put options on futures contracts, (vii) may
write put options on futures contracts and may only write call options on
futures contracts if such call options are covered by: (1) purchased futures
contracts underlying the option, (2) call positions owned on the futures
contracts underlying the call option written, or (3) holdings of securities for
which the written call options are a bona fide hedge, (viii) may purchase
futures contracts as a hedge, (ix) to the extent an asset is used to cover a
particular option, futures contract or option on a futures contract, will not be
able to use such asset to cover any additional option, futures contract or
option on a futures contract, and (x) will only engage in index-based futures or
options transactions if Moody's advises the Corporation in writing that such
transaction will not adversely affect its then-current rating on the AMPS.

      For so long as the shares of AMPS are rated by Moody's, unless, in each
case, Moody's advises the Corporation in writing that such action or actions
will not adversely affect its then-current rating on the AMPS, in determining
the Net Coverage Value of the Corporation's Eligible Assets, the Corporation
shall include as a liability (i) 10% of the exercise value of a written call
option on securities, (ii) 100% of the exercise value of any written put option
on securities, (iii) 10% of the settlement value of the assets underlying
futures contracts sold or call options written on futures contracts, (iv) 100%

      Also, for so long as the shares of AMPS are rated by Moody's, unless, in
each case, Moody's advises the Corporation in writing that such action or
actions will not adversely affect its then-current rating on the AMPS, the
Corporation (i) will limit its transactions in futures contracts and written
options thereon to those relating to U.S. Treasury Bonds, (ii) will not engage
in options and futures transactions for leveraging or speculative purposes,
(iii) will not enter into an options or futures transaction unless after giving
effect to such transaction the Eligible Asset Coverage is met, (iv) shall not
include in Eligible Assets any assets pledged in margin accounts in connection
with futures transactions, (v) will assume for purposes of determining the
Coverage Value, when the Corporation has purchased futures contracts or has
written put options, ownership by the Corporation of the underlying asset, which
will be the security resulting in the lowest Coverage Value when delivery may be
made to the Corporation with any of a class of securities, (vi) will engage only
in exchange traded futures contracts and written options thereon on exchanges
approved by Moody's in writing, which, as of the Date of Original Issue, consist
of the Chicago Board of Trade and the Financial Exchange, (vii) will limit the
transactions in futures contracts sold and call options written on futures
contracts so that the settlement value of the underlying futures contracts does
not in total exceed 65% of the value of the Eligible Assets of the Corporation
rated the equivalent of "baa3" or better by Moody's and not otherwise hedged by
a written call and (viii) will only take positions in futures which are
deliverable in the nearby and next following contract months and will close out
such futures positions by the fifth business day of the delivery month.

      (c) For so long as the shares of AMPS are rated by Moody's, unless, in
each case, Moody's advises the Corporation in writing that such action or
actions will not adversely affect its then-current rating on the AMPS:

            (i) the composition of the Corporation's portfolio will not be
altered if the effect of any such alteration would be to cause the Corporation,
immediately after giving effect to the transaction, to have an Eligible Asset
Coverage Amount equal to or in excess of the Net Coverage Value of Eligible
Assets as of the previous Eligible Asset Evaluation Date;

            (ii) if the Eligible Asset Coverage Amount exceeds the Net Coverage
Value of Eligible Assets, the Corporation will invest the proceeds of the sale
or other disposition of an Eligible Asset in an investment having a greater
Discount Factor or in an issuer in a different industry from the investment sold
or otherwise disposed of only if the effect of such transaction immediately
after giving effect thereto would be to reduce the excess of the Eligible Asset
Coverage Amount over the Net Coverage Value; and

            (iii) at such time that the Net Coverage Value of Eligible Assets is
less than 25% greater than the Eligible Asset Coverage Amount, the composition
of the Corporation's portfolio will not be altered if, in the Corporation's
reasonable judgment, the result of such alteration would cause Eligible Asset
Coverage not to be met.

      (d) By resolution of the Board of Directors and without amending the
Articles or otherwise submitting such resolution for shareholder approval, the
restrictions and procedures set forth in this Section 8 may be adjusted,
modified, altered or changed and any such adjustment, modification, alteration
or change will not be deemed to adversely affect the contract rights of shares
of AMPS or adversely affect the AMPS if Moody's has advised the Corporation in
writing that such adjustment,


                                       22
<PAGE>

modification, alteration or change will not adversely affect its then-current
rating of the AMPS and that any such action will be in accordance with
guidelines established by Moody's.

      9. Auction Agent and AMPS Paying Agent. For so long as any shares of AMPS
are outstanding, the Auction Agent (which shall act as agent of the Corporation
in connection with the implementation of the Auction Procedures) and the AMPS
Paying Agent (which shall act as transfer agent, registrar, dividend disbursing
agent and redemption agent on behalf of the Corporation with respect to AMPS)
shall receive Certificates of Eligible Asset Coverage and related Accountants'
Certificates, shall each be a commercial bank, trust company or other financial
institution unaffiliated with the Corporation or any affiliate of the
Corporation (which, however, may engage or have engaged in business transactions
with the Corporation or any affiliate of the Corporation), and at no time shall
the Corporation or any affiliate of the Corporation act as the Auction Agent or
the AMPS Paying Agent. If the Auction Agent or the AMPS Paying Agent resigns or
for any reason either of their appointments are terminated during any period
that any of the shares of AMPS are outstanding, the Board of Directors shall
promptly thereafter use its best efforts to appoint another qualified commercial
bank, trust company or financial institution to act as the Auction Agent or the
AMPS Paying Agent, as the case may be, upon commercially reasonable terms. A
single qualified commercial bank, trust company or financial institution may act
as the Auction Agent and the AMPS Paying Agent. The AMPS Paying Agent shall
maintain an office or agency in The City of New York for purposes of making
payments on the shares of AMPS.

      10. Notice. All notices or communications, unless otherwise specified in
the By-laws of the Corporation or these Articles Supplementary, shall be
sufficiently given if in writing and delivered in person, transmitted by
telecopy or mailed by first-class mail, postage prepaid. In the event notice is

quotation or quotations furnished by the remaining Commercial Paper Dealer or

            (A) the number of shares, if any, of AMPS subject to any Hold Order
      of such Existing Holder;

            (B) the number of shares, if any, of AMPS subject to any Bid of such

            (iv) the number of shares, if any, of AMPS subject to any Sell Order
of such Holder;

            (v) to the extent such Bidder is a Potential Holder of shares of

      (b) If any rate specified in any Bid contains more than five figures to

      (c) If an Order or Orders covering all of the Outstanding shares of AMPS

Submission Deadline, the Auction Agent shall deem a Hold Order to have been
submitted by or on behalf of such Existing Holder covering the number of
Outstanding shares of AMPS held by such Existing Holder and not subject to
Orders submitted to the Auction Agent; provided, however, that if an Order or
Orders covering all of the Outstanding shares of AMPS held by any Existing
Holder is not submitted to the Auction Agent prior to the Submission Deadline
for an Auction relating to a Rate Period consisting of more than the Minimum
Rate Period, the Auction Agent shall deem a Sell Order to have been submitted by
or on behalf of such Existing Holder covering the number of Outstanding shares
of AMPS held by such Existing Holder and not subject to Orders submitted to the
Auction Agent.

      (d) If one or more Orders of an Existing Holder is submitted to the
Auction Agent covering in the aggregate more than the number of Outstanding
shares of AMPS subject to an Auction held by such Existing Holder, such Orders
shall be considered valid in the following order of priority:

            (i) all Hold Orders for shares of AMPS shall be considered valid,
but only up to and including in the aggregate the number of Outstanding shares
of AMPS held by such Existing Holder, and if the number of shares of AMPS
subject to such Hold Orders exceeds the number of Outstanding shares of AMPS
held by such Existing Holder, the number of shares of AMPS subject


                                       46
<PAGE>

to each such Hold Order shall be reduced pro rata to cover the number of
Outstanding shares of AMPS held by such Existing Holder;

      (ii) (A) any Bid for shares of AMPS shall be considered valid up to and
including the excess of the number of Outstanding shares of AMPS held by such
Existing Holder over the number of shares of AMPS subject to any Hold Orders
referred to in clause (i) above;

            (B) subject to subclause (A), if more than one Bid of an Existing
      Holder is submitted to the Auction Agent with the same rate and the number
      of Outstanding shares of AMPS subject to such Bids is greater than such
      excess, such Bids shall be considered valid up to and including the amount
      of such excess, and the number of shares of AMPS subject to each Bid with
      the same rate shall be reduced pro rata to cover the number of shares of
      AMPS equal to such excess;

            (C) subject to subclauses (A) and (B), if more than one Bid of an
      Existing Holder for shares of AMPS is submitted to the Auction Agent with
      different rates, such Bids shall be considered valid in the ascending
      order of their respective rates up to and including the amount of such
      excess; and

            (D) in any such event, the number, if any, of such Outstanding
      shares of AMPS subject to any portion of Bids considered not valid in
      whole or in part under this clause (ii) shall be treated as the subject of
      a Bid for shares of AMPS by or on behalf of a Potential Holder at the rate
      therein specified; and

            (iii) all Sell Orders for shares of AMPS shall be considered valid
up to and including the excess of the number of Outstanding shares of AMPS held
by such Existing Holder over the sum of shares of AMPS subject to valid Hold
Orders referred to in clause (i) above and valid Bids referred to in clause (ii)
above.

      (e) If more than one Bid for one or more shares of AMPS is submitted to
the Auction Agent by or on behalf of any Potential Holder, each such Bid
submitted shall be a separate Bid with the rate and number of shares of AMPS
therein specified.

Owner to its Broker-Dealer, or by a Broker-Dealer to the Auction Agent, prior to
the Submission Deadline on any Auction Date, shall be irrevocable.

      4. Determination of Sufficient Clearing Bids, Winning Bid Rate and
Applicable Rate.

            (a) Not earlier than the Submission Deadline on each Auction Date,
      the Auction Agent shall assemble all valid 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
      collectively as "Submitted Hold Orders," "Submitted Bids" or "Submitted
      Sell Orders," as the case may be, or as "Submitted Orders") and shall
      determine:


                                       47
<PAGE>

            (i) the excess of the number of Outstanding shares of AMPS over the
number of Outstanding shares of AMPS subject to Submitted Hold Orders (such
excess being hereinafter referred to as the "Available AMPS");

            (ii) from the Submitted Orders whether:

            (A) the number of Outstanding shares of AMPS subject to Submitted
      Bids of Potential Holders specifying one or more rates equal to or lower
      than the Maximum Rate exceeds or is equal to the sum of:

            (B) the number of Outstanding shares of AMPS subject to Submitted
      Bids of Existing Holders specifying one or more rates higher than the
      Maximum Rate; and

            (C) the number of Outstanding shares of AMPS subject to Submitted
Sell Orders (in the event such excess or such equality exists (other than
because the number of shares of AMPS in subclauses (B) and (C) above is zero
because all of the Outstanding shares of AMPS are subject to Submitted Hold
Orders), such Submitted Bids in subclause (A) above being hereinafter referred
to collectively as "Sufficient Clearing Bids"); and

            (iii) if Sufficient Clearing Bids exist, the lowest rate specified
in such Submitted Bids (the "Winning Bid Rate") which if:

            (A) (I) each such Submitted Bid of Existing Holders specifying such
      lowest rate and (II) all other such Submitted Bids of Existing Holders
      specifying lower rates were rejected, thus entitling such Existing Holders
      to continue to hold the shares of AMPS that are subject to such Submitted
      Bids; and

            (B) (I) each such Submitted Bid of Potential Holders specifying such
      lowest rate and (II) all other such Submitted Bids of Potential Holders
      specifying lower rates were accepted, thus requiring such Potential
      Holders to purchase the shares of AMPS that are the subject of such
      Submitted Bids;

would result in such Existing Holders described in subclause (A) above
continuing to hold an aggregate number of Outstanding shares of AMPS which, when
added to the number of Outstanding shares of AMPS to be purchased by such
Potential Holders described in subclause (B) above, would equal not less than
the Available AMPS.

      (b) Promptly after the Auction Agent has made the determinations pursuant
to subparagraph (a) of this Section 4, the Auction Agent shall advise the
Corporation of the Maximum Rate for the shares of AMPS for which an Auction is
being held on the Auction Date and, based on such determination, the Applicable
Rate for the next succeeding Rate Period thereof as follows:

            (i) if Sufficient Clearing Bids exist, that the Applicable Rate for
the next succeeding Rate Period thereof shall be equal to the Winning Bid Rate
so determined;


                                       48
<PAGE>

            (ii) if Sufficient Clearing Bids do not exist (other than because
all of the Outstanding shares of AMPS are subject to Submitted Hold Orders, and
other than in an auction for a Special Rate Period different than the Rate
Period then in effect), that the Applicable Rate for the next succeeding Rate
Period thereof shall be equal to the Maximum Rate for such shares; or

            (iii) if all of the Outstanding shares of AMPS are subject to
Submitted Hold Orders, that the Applicable Rate for the next succeeding Rate
Period thereof shall be equal to either (a) the applicable "AA" Composite
Commercial Paper Rate on the Auction Date for such Rate Period, if such Rate
Period consists of less than 365 days, or (b) the Treasury Rate on such Auction
Date for such Rate Period, if such Rate Period consists of 365 or more days; or

            (iv) if Sufficient Clearing Bids do not exist and the auction was
for a Special Rate Period different than the Rate Period then in effect, then
the Applicable Rate for the next succeeding Rate Period shall be equal to the
Applicable Rate for the Rate Period then in effect.

      5. Acceptance and Rejection of Submitted Bids and Submitted Sell Orders
and Allocation of Shares. Existing Holders shall continue to hold the shares of
AMPS that are subject to Submitted Hold Orders, and, based on the determinations
made pursuant to paragraph (a) of Section 4 of this Part II, the Submitted Bids
and Submitted Sell Orders shall be accepted or rejected by the Auction Agent and
the Auction Agent shall take such other action as set forth below:

      (a) If Sufficient Clearing Bids for shares of AMPS have been made, all
Submitted Sell Orders shall be accepted and, subject to the provisions of
paragraphs (d) and (e) of this Section 5, Submitted Bids shall be accepted or
rejected as follows in the following order of priority and all other Submitted
Bids shall be rejected:

            (i) Existing Holders' Submitted Bids for shares of AMPS specifying
any rate that is higher than the Winning Bid Rate shall be accepted, thus
requiring each such Existing Holder to sell the shares of AMPS subject to such
Submitted Bids;

            (ii) Existing Holders' Submitted Bids for shares of AMPS specifying
any rate that is lower than the Winning Bid Rate shall be rejected, thus
entitling each such Existing Holder to continue to hold the shares of AMPS
subject to such Submitted Bids;

            (iii) Potential Holders' Submitted Bids for shares of AMPS
specifying any rate that is lower than the Winning Bid Rate shall be accepted;

            (iv) each Existing Holder's Submitted Bid for shares of AMPS
specifying a rate that is equal to the Winning Bid Rate shall be rejected, thus
entitling such Existing Holder to continue to hold the shares of AMPS subject to
such Submitted Bid, unless the number of Outstanding shares of AMPS subject to
all such Submitted Bids shall be greater than the number of shares of AMPS
("remaining shares") in the excess of the Available AMPS over the number of
shares of AMPS subject to Submitted Bids described in clauses (ii) and (iii) of
this subparagraph (a), in which event such Submitted Bid of such Existing Holder
shall be rejected in part, and such Existing Holder shall be entitled to
continue to hold shares of AMPS subject to such Submitted Bid, but only in an
amount equal to the number of shares of AMPS obtained by multiplying the number
of remaining


                                       49
<PAGE>

shares by a fraction, the numerator of which shall be the number of Outstanding
shares of AMPS held by such Existing Holder subject to such Submitted Bid and
the denominator of which shall be the aggregate number of Outstanding shares of
AMPS subject to such Submitted Bids made by all such Existing Holders that
specified a rate equal to the Winning Bid Rate; and

            (v) each Potential Holder's Submitted Bid for shares of AMPS
specifying a rate that is equal to the Winning Bid Rate shall be accepted but
only in an amount equal to the number of shares of AMPS obtained by multiplying
the number of shares of AMPS in the excess of the Available AMPS over the number
of shares of AMPS subject to Submitted Bids described in clauses (ii) through
(iv) of this subparagraph (a) by a fraction, the numerator of which shall be the
number of Outstanding shares of AMPS subject to such Submitted Bid and the
denominator of which shall be the aggregate number of Outstanding shares of AMPS
subject to such Submitted Bids made by all such Potential Holders that specified
a rate equal to the Winning Bid Rate; and

      (b) If Sufficient Clearing Bids for shares of AMPS have not been made
(other than because all of the Outstanding shares of AMPS are subject to
Submitted Hold Orders), subject to the provisions of paragraph (d) of this
Section 5, Submitted Orders shall be accepted or rejected as follows in the
following order of priority and all other Submitted Bids shall be rejected:

            (i) Existing Holders' Submitted Bids for shares of AMPS specifying
any rate that is equal to or lower than the Maximum Rate shall be rejected, thus
entitling such Existing Holder to continue to hold the shares of AMPS subject to
such Submitted Bids;

            (ii) Potential Holders' Submitted Bids for shares of AMPS specifying
any rate that is equal to or lower than the Maximum Rate shall be accepted, thus
requiring the Potential Holder to purchase shares of AMPS that are the subject
of such Submitted Bids; and

            (iii) Each Existing Holder's Submitted Bid for shares of AMPS
specifying any rate that is higher than the Maximum Rate of such shares and the
Submitted Sell Orders for shares of AMPS of each Existing Holder shall be
accepted, thus entitling each Existing Holder that submitted or on whose behalf
was submitted any such Submitted Bid or Submitted Sell Order to sell the shares
of AMPS subject to such Submitted Bid or Submitted Sell Order, but in both cases
only in an amount equal to the number of shares of AMPS obtained by multiplying
the number of shares of AMPS subject to Submitted Bids described in clause (ii)
of this subparagraph (b) by a fraction, the numerator of which shall be the
number of Outstanding shares of AMPS held by such Existing Holder subject to
such Submitted Bid or Submitted Sell Order and the denominator of which shall be
the aggregate number of Outstanding shares of AMPS subject to all such Submitted
Bids and Submitted Sell Orders.

      (c) If all of the Outstanding shares of AMPS are subject to Submitted Hold
Orders, all Submitted Bids for such shares shall be rejected.

      (d) If, as a result of the procedures described in clause (iv) or (v) of
paragraph (a) or clause (iii) of paragraph (b) of this Section 5, 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 AMPS on


                                       50
<PAGE>

any Auction Date, the Auction Agent shall, in such manner as it shall determine
in its sole discretion, round up or down the number of shares of AMPS to be
purchased or sold by any Existing Holder or Potential Holder on such Auction
Date as a result of such procedures so that the number of shares of AMPS so
purchased or sold by each Existing Holder or Potential Holder on such Auction
Date shall be whole shares of AMPS.

      (e) If, as a result of the procedures described in clause (v) of paragraph
(a) of this Section 5, any Potential Holder would be entitled or required to
purchase less than a whole share of AMPS on any Auction Date, the Auction Agent
shall, in such manner as it shall determine in discretion, allocate shares of
AMPS for purchase among Potential Holders so that only whole shares of AMPS are
purchased on such Auction Date as a result of such procedures by any Potential
Holder, even if such allocation results in one or more Potential Holders not
purchasing shares of AMPS on such Auction Date.

      (f) Based on the results of each Auction for shares of AMPS, the Auction
Agent shall determine the aggregate number of shares of AMPS to be purchased and
the aggregate number of shares of AMPS to be sold by Potential Holders and
Existing Holders and, with respect to each Potential Holder and Existing
Holders, to the extent that such aggregate number of shares of AMPS to be
purchased and such aggregate number of shares of AMPS to be sold differ,
determine to which other Potential Holder(s) or Existing Holder(s) they shall
deliver, or from which other Potential Holder(s) or Existing Holder(s) they
shall receive, as the case may be, shares of AMPS.

      6. INTENTIONALLY OMITTED

      7. Miscellaneous. (a) The Board of Directors may interpret the provisions

the rights of Beneficial Owners or Existing Holders of shares of AMPS.

      (b) Unless otherwise permitted by the Corporation, a Beneficial Owner or
an Existing Holder may sell, transfer or otherwise dispose of shares of AMPS
only pursuant to a Bid or Sell Order placed with the Auction Agent in accordance
with the procedures described in this Part II or to a Broker-Dealer, provided
that in the case of all transfers other than pursuant to Auctions, (i) such
Beneficial Holder or Existing Holder that is not a Broker-Dealer advises its
Broker-Dealer of such transfer, who in turn advises the Auction Agent of such
transfer and (ii) such Existing Holder that is a Broker-Dealer shall advise the
Auction Agent of such transfer.

      (c) Except as otherwise required by law, Beneficial Owners shall not be
entitled to receive any certificate representing shares of AMPS and their

            (H) with respect to adjustable rate preferred stock ("ARPs"), the

      either directly or in the form of depository receipts, and

            (E) if such issuer is registered as an investment company under the

Eligible Asset if it (A) is held in a margin account, (B) is subject to any
material lien, mortgage, pledge, security interest or security agreement of any
kind or (C) has been deposited irrevocably for the payment of dividends,
redemption payments or any other payment or obligation hereunder.

      (s) "S&P Unseasoned Eligible Assets" shall mean any common stock that

payment of interest and the full payment of principal at maturity. The following
conditions also apply to U.S. Government Obligations:


                                       61
<PAGE>

      (i) If a Treasury interest-only strip is to be considered and eligible
asset, it must apply the over-collateralization level for the Treasury category
following the maturity of the Treasury strip.

security interest in the underlying collateral;

      (iii) The underlying collateral must be free and clear of third-party
claims;

      (iv) The underlying collateral must be registered in the name of the USGO
Trustee;

      (vii) Over-collateralization levels do not apply to zero-coupon
Treasuries.

      2. S&P Coverage Tests.

      (a) Determination of Compliance. For so long as any shares of AMPS are
rated by S&P, the Corporation shall make the following determinations:

            (i) 1940 Act Asset Coverage. The Corporation shall maintain 1940 Act
Asset Coverage as of each Eligible Asset Evaluation Date (as defined in the
Articles Supplementary) during which any share of AMPS is outstanding.

            (ii) S&P Eligible Asset Coverage. For so long as any shares of AMPS
are outstanding, the Corporation shall maintain, on each Eligible Asset
Evaluation Date, S&P Eligible Assets having an aggregate S&P Adjusted Value (the
"Aggregate S&P Value") at least equal to the Eligible Asset Coverage Amount (as
defined in the Articles Supplementary) (the foregoing comparison being the "S&P
Required Asset Coverage") . Upon any failure to meet or exceed the S&P Required
Asset Coverage, the Corporation shall use all commercially reasonable efforts to
re-attain an S&P Required Asset Coverage on or prior to the S&P Coverage Amount
Cure Date, by altering the composition of its portfolio or otherwise.

            (iii) Certificate Regarding Aggregate S&P Value. So long as S&P is
rating the AMPS shares at the request of the Corporation and except to the
extent waived by S&P, as of each Eligible Asset Evaluation Date, the Corporation
shall cause the Administrator to determine the Aggregate S&P Value on that day
and whether such Aggregate S&P Value on such date equals or exceeds the Eligible
Asset Coverage Amount on such date. The calculations of the Aggregate S&P Value
and Eligible Asset Coverage Amount, whether the Aggregate S&P Value equals or
exceeds the Eligible Asset Coverage Amount, shall be set forth in a certificate
(a "Certificate of Aggregate S&P Value"), dated as of each such Eligible Asset
Evaluation Date and signed by an Authorized Officer. The Corporation shall cause
the Administrator to deliver (by facsimile or otherwise) a Certificate of
Aggregate S&P Value to the Corporation no later than 11:00 a.m. New York time on
the third


                                       62
<PAGE>

Business Day immediately following each Eligible Asset Evaluation Date to which
such certificate relates (the "S&P Certificate Due Date").

            (iv) S&P Accountant's Certificate. On each Confirmation Date (as
defined in the Articles Supplementary) following the end of each of the
Corporation's fiscal quarters, the Corporation shall cause the Administrator to
deliver to the Corporation an accountant's certificate (in substantially such
form as may be agreed upon by the Corporation and the Administrator with the
consent of S&P) relating to the last Eligible Asset Evaluation Date of such
fiscal quarter and such other one Eligible Asset Evaluation Date per quarter as
randomly selected by the Corporation's independent accounting firm (the "S&P
Accountant's Certificate") certifying:

            (A) as to the mathematical accuracy of the calculations reflected in
      the related Certificate of Aggregate S&P Value, including the calculation
      of the S&P Adjusted Value of the S&P Eligible Assets referred to therein
      and confirming that the S&P Eligible Assets referred to therein conform to
      the definition of S&P Eligible Assets herein,

            (B) that the methodology used by the Administrator in determining
      whether the Aggregate S&P Value equals or exceeds the Eligible Asset
      Coverage Amount is in accordance with the applicable requirements of these
      Articles, and

            (C) that the written or published price quotations used in such
      determination conform to such written or published quotations and that the
      S&P Eligible Assets listed in such certificate constitute S&P Eligible
      Assets as defined herein.

If the S&P Accountant's Certificate is not delivered to the Corporation when
required, the S&P Required Asset Coverage will be deemed not to have been met as
of the applicable date. If such Accountant's Certificate shall differ from the
Administrator's calculations, then the Accountant's Certificate shall control
unless any such difference results from an error in calculation by the preparers
of the Accountant's Certificate.

      (b) Notice of S&P Required Asset Coverage. The Corporation shall cause to
be delivered to S&P, promptly after receipt thereof by the Corporation, but in
no event later than the close of business on the second Business Day next
succeeding the following dates, the Certificate of Aggregate S&P Value with
respect to each of the following dates:

            (i) each date as of which the S&P Required Asset Coverage is less
than the Eligible Asset Coverage Amount,

            (ii) each S&P Cure Date,

            (iii) each S&P Certificate Due Date (e.g., weekly) as of which the
S&P Required Asset Coverage is less than or equal to 125% of the Eligible Asset
Coverage Amount,

            (iv) the first and every other S&P Certificate Due Date (e.g.,
bi-weekly) during the one-year period immediately following the First S&P
Evaluation Date and, after such one-year period,


                                       63
<PAGE>

on the first S&P Certificate Due Date (e.g., the first Friday) occurring in each
of the Corporation's fiscal quarters,

            (v) each date of common stock repurchase; and

            (vi) whenever otherwise requested by S&P.

      (c) Delivery of S&P Accountant's Certificate to S&P. The Corporation shall
cause to be delivered to S&P as soon as practicable after receipt thereof (but
in no event later than 5 Business Days after the Corporation's receipt thereof)
the S&P Accountant's Certificate with respect to each of the following dates:

            (i) each S&P Cure Date; and

            (ii) each Confirmation Date immediately following the end of each of
the Corporation's fiscal quarters as well as a verification of the S&P Required
Asset Coverage for a single, randomly selected date (as selected by Accountant)
during each such fiscal quarter.

      (d) Failure to Meet 1940 Act Asset Coverage. If the Corporation fails to
meet or exceed the 1940 Act Asset Coverage, the Corporation shall give the
notices and be subject to the covenants set forth in Part 1, Section
3(a)(iii)(A) of the Articles Supplementary.

      (e) Failure to Maintain the S&P Required Asset Coverage. If the
Corporation fails to meet or exceed the S&P Required Asset Coverage and such
failure is not cured by the related S&P Cure Date, the Corporation shall, by the
close of business no later than the third Business Day following such S&P Cure
Date:

            (i) notify the AMPS Paying Agent of its intention to redeem on the
earliest practicable date following such S&P Cure Date the number of shares of
AMPS determined as provided below and

            (ii) give a Notice of Redemption (which shall specify a mandatory
redemption date that is not fewer than 3 days nor more than 33 days after the
date of such notice) with respect to the redemption of shares of AMPS on such
mandatory redemption date.

The Corporation shall redeem, out of funds legally available therefor, the
number of shares of AMPS equal to the minimum number of shares the redemption of
which, if such redemption had occurred immediately prior to the opening of
business on such S&P Cure Date, would have resulted in the S&P Required Asset
Coverage having been met on such S&P Cure Date or, if the S&P Required Asset
Coverage cannot be restored, all of the shares of AMPS, at a redemption price
equal to $100,000 per share (without payment of any premium) plus an amount
equal to all dividends (whether or not earned or declared) accumulated thereon
up to but not including such mandatory redemption date and unpaid (an "S&P
Redemption"). In the event of an S&P Redemption pursuant to this subparagraph
(e), such redemption shall not be effected on either of the two Business Days
immediately preceding an Auction Date. Upon the occurrence of the conditions
necessary to give rise to an S&P Redemption, if there has been a termination of
any


                                       64
<PAGE>

Adviser which results in a vacancy with respect to an officer of the Corporation
who may be authorized to effect an S&P Redemption under this subparagraph, the
Administrator shall be and is hereby authorized and directed to effect such S&P
Redemption until such time as the Corporation has replaced the vacancy and such
officer is sufficiently capable of causing such S&P Redemption to be efficiently
conducted.

      (f) Status of Shares Called for Redemption. For purposes of determining
whether the requirements of paragraphs 2(a)(i) and 2(a)(ii) of this Part III are
satisfied:

            (i) no share of the AMPS shall be deemed to be "outstanding" for
purposes of any computation if, prior to or concurrently with such
determination, sufficient Deposit Securities to pay the full Redemption Price
for such share shall have been deposited in trust with the AMPS Paying Agent and
the requisite Notice of Redemption shall have been given, and

            (ii) such Deposit Securities deposited with the AMPS Paying Agent
shall not be included in determining whether the requirements of paragraphs
2(a)(i) and 2(a)(ii) of this Part III are satisfied.

      3. Certain Other Restrictions.

      (a) Alteration of the Portfolio. For so long as the AMPS is rated by S&P,
the Corporation will not, and will cause the Adviser not to:

            (i) knowingly and willfully purchase or sell any asset for the
specific purpose of causing, and with the actual knowledge that the effect of
such purchase or sale will be to cause, the Corporation to fail to meet the S&P
Required Asset Coverage as of the date of such purchase or sale;

            (ii) in the event that, as of the immediately preceding Eligible
Asset Evaluation Date, the Aggregate S&P Value exceeded the S&P Required Asset
Coverage by 25% or less, alter the composition of the Corporation's assets in a
manner reasonably expected to reduce the Aggregate S&P Value, unless the
Corporation shall have confirmed that, after giving effect to such alteration,
the Aggregate S&P Value exceeded the S&P Required Asset Coverage; or

            (iii) declare or pay any dividend or other distribution on any
shares of the Common Stock or repurchase any shares of Common Stock, unless the
Corporation shall have confirmed that, after giving effect to such declaration,
other distribution or repurchase, the Corporation continued to satisfy the
requirements of Subsection 2(a)(ii) of this Part III.

      (b) Notice Regarding Business Combinations. For so long as the AMPS is
rated by S&P, the Corporation shall not consolidate with, merge the Corporation
into, sell or otherwise transfer all or substantially all of the Corporation's
assets to another entity or adopt a plan of liquidation of the Corporation, in
each case without providing prior written notification to S&P.

      (c) Hedging Transactions. For so long as any shares of AMPS are rated by
S&P, the Corporation will not purchase or sell futures contracts, write,
purchase or sell options on futures


                                       65
<PAGE>

contracts 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 AMPS by S&P, except that the Corporation may
purchase or sell futures contracts based on the Bond Buyer Municipal Bond Index
(the "Municipal Index") or United States Treasury Bonds or Notes ("Treasury
Bonds") and write, purchase or sell all put and call options on such contracts
(collectively, "S&P Hedging Transactions"), subject to the following
limitations:

            (i) The Corporation will not engage in any S&P Hedging Transaction
based on the Municipal Index other than transactions which terminate a futures
contract or option held by the Corporation by taking an opposite position
thereto ("Closing Transactions"), which would cause the Corporation at the time
of such transaction to own or have sold the least of (a) more than 1000
outstanding futures contracts based on the Municipal Index, (b) outstanding
futures contracts based on the Municipal Index exceeding in number 25 percent of
the quotient of the Market Value of the Corporation's total assets divided by
$1000, or (c) outstanding futures contracts based on the Municipal Index
exceeding in number 10 percent of the average number of daily traded futures
contracts based on the Municipal Index in the 30 days preceding the time of the
effecting such transactions as reported by the Wall Street Journal;

            (ii) The Corporation will not engage in any S&P Hedging Transaction
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
(a) outstanding futures contracts based on Treasury Bonds exceeding in number 50
percent of the quotient of the Market Value of the Corporation's total assets
divided by $100,000 ($200,000 in the case of the two-year United States Treasury
Note) or (b) outstanding futures contracts based on Treasury Bonds exceeding in
number 10 percent of the average number of daily traded futures contracts based
on Treasury Bonds in the 30 days preceding the time of effecting such
transaction as reported by The Wall Street Journal;

            (iii) The Corporation will not 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 (a)
the Corporation does not have S&P Eligible Assets with an aggregate S&P
Discounted Value equal to or greater than the S&P Required Asset Coverage on two
consecutive Eligible Asset Evaluation Dates and (b) the Corporation is required
to pay additional margin due to fluctuation in contract price ("to") on the
second such evaluation date;

            (iv) The Corporation will engage in a Closing Transaction to close
out of any outstanding futures contract or option thereon in the month prior to
the delivery month under the terms of such futures contract or option there on
unless the Corporation holds the securities deliverable under such terms; and

            (v) When the Corporation writes a futures contract or option
thereon, it will either maintained an amount of cash, cash equivalents or
high-grade (rated "A" or better by S&P) fixed income securities in a segregated
account with the Corporation's custodian, so that the amount so segregated plus
the amount of margin paid on such contract ("Initial Margin") and any Variation
Margin held in the amount of or on behalf of the Corporation's broker with
respect to such futures contract or option equals the Market Value of the
futures contract or option, or, in the event the


                                       66
<PAGE>

Corporation writes a futures contract or option thereon which requires delivery
of an underlying security, it shall hold such an underlying security in its
portfolio.

For purposes of determining whether the Corporation has S&P Eligible Assets with
an S&P Discounted Value that equals or exceeds S&P Required Asset Coverage, the
S&P Discounted Value of cash or securities held for the payment of Initial
Margin or Variation Margin shall be zero and the aggregate S&P Discounted Value
of the S&P Eligible Assets shall be reduced by an amount equal to (a) 30 percent
of the aggregate settlement value, as marked to market, of any outstanding
futures contracts based on the Municipal Index which are owned by the
Corporation plus (b) 25 percent of the aggregate settlement value, as marked
market, of any outstanding futures contract based on Treasury Bonds which
contracts are owned by the Corporation.

      (d) Restrictions on Borrowing, Guarantees and Other Rating Agency
Restrictions. The Corporation shall not, for so long as AMPS shares are rated by
S&P, unless it has received written confirmation from S&P that such action would
not impair the ratings then assigned to AMPS shares by S&P:

            (i) Borrow money; provided, however, that

            (A) the Corporation may, without obtaining the written confirmation
      described above, borrow money for the purpose of clearing securities
      transactions if (1) the S&P Required Asset Coverage would continue to be
      satisfied after giving effect to such borrowing, and (2) such borrowing is
      privately arranged with a bank or other person and is evidenced by a
      promissory note or other evidence of indebtedness that is not intended to
      be publicly distributed or (3) is for "temporary purposes," is evidenced
      by a promissory note or other evidence of indebtedness and is of an amount
      not exceeding the lesser of 5% of the value of the total assets of the
      Corporation at the time of the borrowing or $10 million. As used in this
      subparagraph, the term "temporary purpose" shall mean that the borrowing
      is to be repaid within sixty (60) days and is not to be extend or renewed;
      and

            (B) the Corporation may, with written notice to and authorization
      from S&P, borrow for the specific purpose of redeeming the AMPS shares;

            (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 AMPS 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 AMPS shares previously purchased or redeemed by the
Corporation;

            (vi) Merge or consolidate into or with any other corporation or
entity;


                                       67
<PAGE>

            (vii) Change the pricing methodology contemplated in the definition
of Market Value in the Articles Supplementary, or with respect to common stocks,
change the pricing services previously approved by S&P (e.g., Bloomberg and
Reuters) without written approval from S&P; or

            (viii) Engage in reverse repurchase agreements.

      (e) Statement Regarding Insolvency and Bankruptcy. The Corporation has no
intention to file a voluntary application or relief under Federal bankruptcy law
or any similar application under state law so long as the Corporation is solvent
and does not foresee becoming insolvent The S&P Rating with respect to the AMPS
is not a recommendation to purchase, hold or sell the AMPS shares, inasmuch as
the rating does not comment as to market price or suitability for a particular
investor, nor do the S&P guidelines described herein address the likelihood that
a holder of AMPS shares will be able to sell such shares in an Auction.

      (f) Additional Covenants of the Corporation.

            (i) Insolvency. So long as any shares of AMPS are outstanding, the
Corporation shall not file a voluntary application for relief under Federal
bankruptcy law or any similar application under state law, without the
affirmative vote or consent of the Holders of at least 66 2/3% of the shares of
AMPS outstanding at the time, in person or by proxy, either in writing or at a
meeting, voting as a separate class.

            (ii) Required Notifications. The Corporation shall promptly notify
S&P of any termination or resignation of the Adviser, or its successor, or of
any sub-adviser of the Corporation, or their successors.

      4. Conflicts With Other Provisions. The terms and conditions of this Part
III are intended to (i) be complementary to, and not in conflict with, the terms
and conditions of Part I of these Articles (e.g., with respect to Moody's
coverage) and (ii) impose on the Corporation an obligation to satisfy an
"additional" rather than "substituted" eligible asset analysis and calculation.
The terms and conditions of this Part III shall be construed broadly and in such
a way as to give the foregoing intentions their full effect. In light of the
foregoing, to the extent that any term or condition of this Part III shall
conflict with a term of Part I of these Articles, the more restrictive provision
(as to the obligations of the Corporation) shall prevail.
