issued by the same issuer and rated Baa by Moody's or A by S&P may comprise no
more than 6% of total Moody's Eligible Assets; such BBB, Baa and A-rated
Municipal Obligations and Unrated Moody's Municipal Obligations, if any,
together with any Municipal Obligations issued by the same issuer and rated A
by Moody's or AA by S&P, may comprise no more than 10% of total Moody's
Eligible Assets; and such BBB, Baa, A and AA-rated Municipal Obligations and
Unrated Moody's Municipal Obligations, if any, together with any Municipal

<PAGE>

Obligations issued by the same issuer and rated Aa by Moody's or AAA by S&P,
may comprise no more than 20% of total Moody's Eligible Assets. For purposes of
the foregoing sentence, any Municipal Obligation backed by the guaranty, letter
of credit or insurance issued by a third party shall be deemed to be issued by
such third party if the issuance of such third-party credit is the sole
determinant of the rating on such Municipal Obligations. Municipal Obligations
issued by issuers located within a single state or territory and not rated by
Moody's or rated lower than Baa3 by Moody's and not rated by S&P or rated lower
than BBB by S&P may comprise no more than 12% of total Moody's Eligible Assets;
such Unrated Moody's Municipal Obligations, if any, together with any Municipal
Obligations issued by issuers located within the same state or territory and
rated BBB by S&P may comprise no more than 12% of total Moody's Eligible
Assets; such BBB-rated Municipal Obligations and Unrated Moody's Municipal
Obligations, if any, together with any Municipal Obligations issued by issuers
located within the same state or territory and rated Baa by Moody's or A by
S&P, may comprise no more than 20% of total Moody's Eligible Assets; such BBB,
Baa and A-rated Municipal Obligations and Unrated Moody's Municipal
Obligations, if any, together with any Municipal Obligations issued by issuers
located within the same state or territory and rated A by Moody's or AA by S&P,
may comprise no more than 40% of total Moody's Eligible Assets; and such BBB,
Baa, A and AA-rated Municipal Obligations and Unrated Moody's Municipal
Obligations, if any, together with any Municipal Obligations issued by issuers
located within the same state or territory and rated Aa by Moody's or AAA by
S&P, may comprise no more than 60% of total Moody's Eligible Assets. Municipal
Obligations which are not rated by Moody's or S&P may comprise no more than 40%
of the aggregate Market Value of Moody's Eligible Assets; provided, however,
that if the Market Value of such Municipal Obligations exceeds 40% of the
aggregate Market Value of Moody's Eligible Assets, a portion of such Municipal
Obligations (selected by the Trust) shall not be considered Moody's Eligible
Assets, so that the Market Value of such Municipal Obligations (excluding such
portion) does not exceed 40% of the aggregate Market Value of Moody's Eligible
Assets; provided, however, that no such unrated Municipal Obligation shall be
considered a Moody's Eligible Asset if such Municipal Obligation shall be in
"default", which term shall mean for purposes of this definition, either (a)
the nonpayment by the issuer of interest or principal when due or (b) the
notification of the Trust by the trustee under the underlying indenture or
other governing instrument for such Municipal Obligation that the issuer will
fail to pay when due principal or interest on such Municipal Obligation. For
purposes of applying the foregoing requirements, a Municipal Obligation shall
be deemed to be rated BBB by S&P if rated BBB-, BBB or BBB+ by S&P, Moody's
Eligible Assets shall be calculated without including cash, and Municipal
Obligations rated MIG-1, VMIG-1 or P-1 or, if not rated by Moody's, rated
A-1+/Aa or SP-1+/AA by S&P, shall be considered to have a long-term rating of
A. When the Trust sells a Municipal Obligation and agrees to repurchase such
Municipal Obligation at a future day, such Municipal Obligation shall be valued
at its Discounted Value for purposes of determining Moody's Eligible Assets,
and the amount of the repurchase price of such Municipal Obligation shall be
included as a liability for purposes of calculating the Municipal Preferred
Basic Maintenance Amount. When the Trust purchases a Moody's Eligible Asset and
agrees to sell it at a future date, such Eligible Asset shall be valued at the
amount of cash to be received by the Trust upon such future date, provided that
the counterparty to the transaction has a long-term debt rating of at least A2
and a short-term debt rating of at least P1 from Moody's and the transaction
has a term of no more than 30 days; otherwise such Eligible Asset shall be
valued at the Discounted Value of such Eligible Asset. For purposes of
determining the aggregate Discounted Value of Moody's Eligible Assets, such
aggregate amount shall be reduced with respect to any futures contracts as set
forth in paragraph 10(a) of this Part I.

     Notwithstanding the foregoing, an asset will not be considered a Moody's
Eligible Asset to the extent it is (i) subject to any material lien, mortgage,
pledge, security interest or security agreement of any kind (collectively,
"Liens"), except for (a) Liens which are being contested in good faith by
appropriate proceedings and which Moody's has indicated to the Trust will not
affect the status of such asset as a Moody's Eligible Asset, (b) Liens for
taxes that are not then due and payable or that can be paid thereafter without
penalty, (c) Liens to secure payment for services rendered or cash advanced to
the Trust by [Massachusetts Financial Services Company], [The Chase Manhattan
Bank] or the Auction Agent and (d) Liens by virtue of any repurchase agreement

or futures contract; or (ii) deposited irrevocably for the payment of any
liabilities for purposes of determine the Municipal Preferred Basic Maintenance
Amount.

Days or fewer, or any Special Rate Period of 57 Rate Period Days or more, a
multiplicative factor equal to 275%, except as otherwise provided in the last
sentence of this definition; (ii) in the case of any Special Rate Period of
more than 28 but fewer than 36 Rate Period Days, a multiplicative factor equal
to 203%; (iii) in the case of any Special Rate Period of more than 35 but fewer
than 43 Rate Period Days, a multiplicative factor equal to 217%; (iv) in the
case of any Special Rate Period of more than 42 but fewer than 50 Rate Period
Days, a multiplicative factor equal to 226%; and (v) in the case of any Special
Rate Period of more than 49 but fewer than 57 Rate Period Days, a
multiplicative factor equal to 235%. If, as a result of the enactment of
changes to the Code, the greater of the maximum marginal Federal individual
income tax rate applicable to ordinary income and the maximum marginal Federal
corporate income tax rate applicable to ordinary income will increase, such
increase being rounded up to the next five percentage points (the "Federal Tax
Rate Increase"), until the effective date of such increase, the Moody's
Volatility Factor in the case of any Rate Period described in (i) above in this
definition instead shall be determined by reference to the following table:

                  Federal                        Volatility
            Tax Rate Increase                      Factor

                   5%                              295%

shares of each series of Municipal Preferred outstanding from such first
respective Dividend Payment Date therefor through the 49th day after such
Valuation Date, at the Maximum Rate (calculated as if such Valuation Date were

Payment Date, assuming, solely for purposes of the foregoing, that if on such
Valuation Date the Trust shall have delivered a Notice of Special Rate Period
to the Auction Agent pursuant to paragraph 4(d)(i) of this Part I with respect
to shares of such series, such Maximum Rate shall be the higher of (a) the

the equivalent of the rating category in which such Municipal Obligation is
placed by such other nationally recognized credit rating agency. For purposes
of the foregoing, Anticipation Notes rated SP-1+ or, if not rated by S&P, rated

credit rating agency, is rated at least A by such agency; (iv) is not part of a
private placement of Municipal Obligations (except in the case of Inverse
Floaters); (v) is part of an issue of Municipal Obligations with an original

subparagraph (d) of this paragraph 2. Holders of shares of Municipal Preferred
shall not be entitled to any dividend, whether payable in cash, property or

      series on the first Business Day that falls after such Wednesday or
      Friday, as the case may be; and

            (ii) notwithstanding the foregoing provisions of this paragraph
      2(d), the Trust in its discretion may establish the Dividend Payment
      Dates in respect of any Special Rate Period of shares of a series of

<PAGE>

     (e) DIVIDEND RATES AND CALCULATION OF DIVIDENDS.

            (i) DIVIDEND RATES. The dividend rate on shares of Municipal
      Preferred of any series during the period from and after the Date of
      Original Issue of shares of such series to and including the last day of
      the Initial Rate Period of shares of such series shall be equal to the
      rate per annum set forth with respect to shares of such series under
      "Designation" in this Part I. For each Subsequent Rate Period of shares
      of such series thereafter, the dividend rate on shares of such series
      shall be equal to the rate per annum that results from an Auction for
      shares of such series on the Auction Date next preceding such Subsequent
      Rate Period; provided, however, that if:

                  (A) an Auction for any such Subsequent Rate Period is not
            held for any reason other than as described below, the dividend
            rate on shares of such series for such Subsequent Rate Period will
            be the Maximum Rate for shares of such series on the Auction Date
            therefor;

                  (B) any Failure to Deposit shall have occurred with respect
            to shares of such series during any Rate Period thereof (other than
            any Special Rate Period consisting of more than 364 Rate Period
            Days or any Rate Period succeeding any Special Rate Period
            consisting of more than 364 Rate Period Days during which a Failure
            to Deposit occurred that has not been cured), but, 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 have been cured in accordance with subparagraph (f)
            of this paragraph 2 and the Trust shall have paid to the Auction
            Agent a late charge ("Late Charge") equal to the sum of (1) if such
            Failure to Deposit consisted of the failure timely to pay to the
            Auction Agent the full amount of dividends with respect to any
            Dividend Period of the shares of such series, an amount computed by
            multiplying (x) 200% of the Reference 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 subparagraph (f) of this
            paragraph 2 (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 Liquidation Preference of the outstanding
            shares of such series and (2) if such Failure to Deposit consisted
            of the failure timely to pay to the Auction Agent the Redemption
            Price of the shares, if any, of such series for which Notice of
            Redemption has been mailed by the Trust pursuant to paragraph 11(c)
            of this Part I, an amount computed by multiplying (x) 200% of the
            Reference 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 subparagraph (f)
            of this paragraph 2 (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 Liquidation Preference of the
            outstanding shares of such series to be redeemed, no Auction will
            be held in respect of shares of such series for the Subsequent Rate
            Period thereof and the dividend rate for shares of such series for

<PAGE>

            such Subsequent Rate Period will be the Maximum Rate for shares of
            such series on the Auction Date for such Subsequent Rate Period;

                  (C) any Failure to Deposit shall have occurred with respect
            to shares of such series during any Rate Period thereof (other than
            any Special Rate Period consisting of more than 364 Rate Period
            Days or any Rate Period succeeding any Special Rate Period
            consisting of more than 364 Rate Period Days 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 subparagraph
            (f) of this paragraph 2 or the Trust shall not have paid the
            applicable Late Charge to the Auction Agent, no Auction will be
            held in respect of shares of such series for the first Subsequent
            Rate Period thereof thereafter (or for any Rate Period thereof
            thereafter to and including the Rate Period during which (1) such
            Failure to Deposit is cured in accordance with subparagraph (f) of
            this paragraph 2 and (2) the Trust pays the applicable Late Charge
            to the Auction Agent (the condition set forth in this clause (2) to
            apply only in the event Moody's is rating such shares at the time
            the Trust cures such Failure to Deposit), in each case no later
            than 12:00 Noon, New York City time, on the fourth Business Day
            prior to the end of such Rate Period), and the dividend rate for
            shares of such series for each such Subsequent Rate Period shall be
            a rate per annum equal to the Maximum Rate for shares of such
            series on the Auction Date for such Subsequent Rate Period (but
            with the prevailing rating for shares of such series, for purposes
            of determining such Maximum Rate, being deemed to be "Below
            'ba3'/BB-"); or

                  (D) any Failure to Deposit shall have occurred with respect
            to shares of such series during a Special Rate Period thereof
            consisting of more than 364 Rate Period Days, or during any Rate
            Period thereof succeeding any Special Rate Period consisting of
            more than 364 Rate Period Days during which a Failure to Deposit
            occurred that has not been cured, and, prior to 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, such
            Failure to Deposit shall not have been cured in accordance with
            subparagraph (f) of this paragraph 2 or, in the event Moody's is
            then rating such shares, the Trust shall not have paid the
            applicable Late Charge to the Auction Agent (such Late Charge, for
            purposes of this subparagraph (D), to be calculated by using, as
            the Reference Rate, the Reference Rate applicable to a Rate Period
            (x) consisting of more than 182 Rate Period Days but fewer than 365
            Rate Period Days and (y) commencing on the date on which the Rate
            Period during which Failure to Deposit occurs commenced), no
            Auction will be held in respect of shares of such series for such
            Subsequent Rate Period (or for any Rate Period thereof thereafter
            to and including the Rate Period during which (1) such Failure to
            Deposit is cured in accordance with subparagraph (f) of this
            paragraph 2 and (2) the Trust pays the applicable Late Charge to
            the Auction Agent (the condition set forth in this clause (2) to
            apply only in the event Moody's is rating such shares at the time
            the Trust cures such Failure to Deposit), in each case no later
            than 12:00 Noon, New York City time, on the fourth Business Day
            prior to the end of such Rate Period), and the dividend rate for
            shares of such series for each such Subsequent Rate Period shall be
            a rate per annum equal to the Maximum Rate for shares of such
            series on the Auction Date for such Subsequent Rate Period (but
            with the prevailing rating for shares of such series, for purposes

<PAGE>

            of determining such Maximum Rate, being deemed to be "Below
            'ba3'/BB-") (the rate per annum of which dividends are payable on
            shares of a series of Municipal Preferred for any Rate Period
            thereof being herein referred to as the "Applicable Rate" for
            shares of such series).

            (ii) CALCULATION OF DIVIDENDS. The amount of dividends per share
      payable on shares of a series of Municipal Preferred on any date on which
      dividends shall be payable on shares of such series shall be computed by
      multiplying the Applicable Rate for shares of such series 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 365 if such Dividend Period
      consists of 7 Rate Period Days and 360 for all other Dividend Periods,
      and applying the rate obtained against $25,000.

     (f) CURING A FAILURE TO DEPOSIT. A Failure to Deposit with respect to
shares of a series of Municipal Preferred shall have been cured (if such
Failure to Deposit is not solely due to the willful failure of the Trust to
make the required payments to the Auction Agent) with respect to any Rate
Period of shares of such series if, within the respective time periods
described in subparagraph (e)(i) of this paragraph 2, the Trust shall have paid
to the Auction Agent (A) all accumulated and unpaid dividends on shares of such
series and (B) without duplication, the Redemption Price for shares, if any, of
such series for which Notice of Redemption has been mailed by the Trust
pursuant to paragraph 11(c) of Part I of this Statement; provided, however,
that the foregoing clause (B) shall not apply to the Trust's failure to pay the
Redemption Price in respect of shares of Municipal Preferred when the related
Redemption Notice provides that redemption of such shares is subject to one or
more conditions precedent and any such condition precedent shall not have been
satisfied at the time or times and in the manner specified in such Notice of
Redemption.

     (g) DIVIDEND PAYMENTS BY TRUST TO AUCTION AGENT. The Trust shall pay to
the Auction Agent, not later than 12:00 Noon, New York City time, on the
Business Day next preceding each Dividend Payment Date for shares of a series
of Municipal Preferred, 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 of shares of such series on such Dividend Payment Date.

     (h) AUCTION AGENT AS TRUSTEE OF DIVIDEND PAYMENTS BY TRUST. All moneys
paid to the Auction Agent for the payment of dividends (or for the payment of
any Late Charge) shall be held in trust for the payment of such dividends (and
any such Late Charge) by the Auction Agent for the benefit of the Holders
specified in subparagraph (i) of this paragraph 2. Any moneys paid to the
Auction Agent in accordance with the foregoing but not applied by the Auction
Agent to the payment of dividends (and any such Late Charge) will, to the
extent permitted by law, be repaid to the Trust at the end of 90 days from the
date on which such moneys were so to have been applied.

     (i) DIVIDENDS PAID TO HOLDERS. Each dividend on shares of Municipal
Preferred shall be paid on the Dividend Payment Date therefor to the Holders
thereof as their names appear on the record books of the Trust on the Business
Day next preceding such Dividend Payment Date.


<PAGE>

     (j) DIVIDENDS CREDITED AGAINST EARLIEST ACCUMULATED BUT UNPAID DIVIDENDS.
Any dividend payment made on shares of Municipal Preferred shall first be
credited against the earliest accumulated but unpaid dividends due with respect
to such shares. 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 record books of the
Trust on such date, not exceeding 15 days preceding the payment date thereof,
as may be fixed by the Board of Trustees.

     (k) DIVIDENDS DESIGNATED AS EXEMPT-INTEREST DIVIDENDS. Dividends on shares
of Municipal Preferred shall be designated as exempt-interest dividends up to
the amount of tax-exempt income of the Trust, to the extent permitted by, and

OR FEWER. If, in the case of any Minimum Rate Period or any Special Rate Period
of 28 Rate Period Days or fewer, the Trust allocates any net capital gain or
other income taxable for Federal income tax purposes to a dividend paid on
shares of Municipal Preferred without having given advance notice thereof to
the Auction Agent as provided in paragraph 5 of Part II of this Statement (such
allocation being referred to herein as a "Taxable Allocation") solely by reason
of the fact that such allocation is made retroactively as a result of the
redemption of all or a portion of the outstanding shares of Municipal Preferred
or the liquidation of the Trust, the Trust shall, prior to the end of the
calendar year in which such dividend was paid, provide notice thereof to the
Auction Agent and direct the Trust's dividend disbursing agent to send such
notice with a Gross-up Payment to each Holder of such shares that was entitled
to such dividend payment during such calendar year at such Holder's address as
the same appears or last appeared on the record books of the Trust.

     (b) SPECIAL RATE PERIODS OF MORE THAN 28 RATE PERIOD DAYS. If, in the case
of any Special Rate Period of more than 28 Rate Period Days, the Trust makes a
Taxable Allocation to a dividend paid on shares of Municipal Preferred, the
Trust shall, prior to the end of the calendar year in which such dividend was
paid, provide notice thereof to the Auction Agent and direct the Trust's
dividend disbursing agent to send such notice with a Gross-up Payment to each
Holder of shares that was entitled to such dividend payment during such
calendar year at such Holder's address as the same appears or last appeared on
the record books of the Trust.

     (c) NO GROSS-UP PAYMENTS IN THE EVENT OF A REALLOCATION. The Trust shall
not be required to make Gross-up Payments with respect to any net capital gain
or other taxable income determined by the Internal Revenue Service to be
allocable in a manner different from that allocated by the Trust.

     4. DESIGNATION OF SPECIAL RATE PERIODS.

     (a) LENGTH OF AND PRECONDITIONS FOR SPECIAL RATE PERIOD. The Trust, at its
option, may designate any succeeding Subsequent Rate Period of shares of a
series of Municipal Preferred as a Special Rate Period consisting of a
specified number of Rate Period Days evenly divisible by seven and not more
than 1,820, subject to adjustment as provided in subparagraph (b) of this
paragraph 4. A designation of a Special Rate Period shall be effective only if
(A) notice thereof shall have been given in accordance with subparagraphs (c)
and (d)(i) of this paragraph 4, (B) an Auction for shares of such series shall
have been held on the Auction Date immediately preceding the first day of such
proposed Special Rate Period and Sufficient Clearing Bids for shares of such
series shall have existed in such Auction, and (C) if any Notice of Redemption
shall have been mailed by the Trust pursuant to paragraph 11(c) of this Part I
with respect to any shares of such series, the Redemption Price with respect to
such shares shall have been deposited with the Auction Agent. In the event the
Trust wishes to designate any succeeding Subsequent Rate Period for shares of a
series of Municipal Preferred as a Special Rate Period consisting of more than
28 Rate Period Days, the Trust shall notify S&P (if S&P is then rating such
series) and Moody's (if Moody's is then rating such series) in advance of the
commencement of such Subsequent Rate Period that the Trust wishes to designate
such Subsequent Rate Period as a Special Rate Period and shall provide S&P (if
S&P is then rating such series) and Moody's (if Moody's is then rating such
series) with such documents as either may request.

     (b) ADJUSTMENT OF LENGTH OF SPECIAL RATE PERIOD. In the event the Trust
wishes to designate a Subsequent Rate Period as a Special Rate Period, but the
day following what would otherwise be the last day of such Special Rate Period
is not (a) a Wednesday that is a Business Day in the case of a series of
Municipal Preferred designated as "Series W Municipal Preferred" in this Part
I, or (b) a Friday that is a Business Day in the case of a series of Municipal
Preferred designated as "Series F Municipal Preferred" in this Part I, then the
Trust shall designate such Subsequent Rate Period as a Special Rate Period
consisting of the period commencing on the first day following the end of the
immediately preceding Rate Period and ending (a) on the first Tuesday that is
followed by a Wednesday that is a Business Day proceeding what would otherwise
be such last day, in the case of Series W Municipal Preferred, or (b) on the
first Thursday that is followed by a Friday that is a Business Day proceeding
what would otherwise be such last day in the case of Series F Municipal
Preferred.

     (c) NOTICE OF PROPOSED SPECIAL RATE PERIOD. If the Trust proposes to
designate any succeeding Subsequent Rate Period of shares of a series of
Municipal Preferred as a Special Rate Period pursuant to subparagraph (a) of
this paragraph 4, not less than 20 (or such lesser number of days as may be
agreed to from time to time by the Auction Agent) nor more than 30 days prior
to the date the Trust 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 (i) published or caused to be published
by the Trust in a newspaper of general circulation to the financial community
in The City of New York, New York, which carries financial news, and (ii)
mailed by the Trust by first-class mail, postage prepaid, to the Holders of
shares of such series. Each such notice shall state (A) that the Trust may
exercise its option to designate a succeeding Subsequent Rate Period of shares
of such series as a Special Rate Period, specifying the first day thereof and
(B) that the Trust will, by 11:00 A.M., New York City time, on the second
Business Day next preceding such date (or by such later time or date, or both,
as may be agreed to by the Auction Agent) notify the Auction Agent of either
(x) its determination, subject to certain conditions, to exercise such option,

<PAGE>

in which case the Trust shall specify the Special Rate Period designated, or
(y) its determination not to exercise such option.

     (d) NOTICE OF SPECIAL RATE PERIOD. No 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 of shares of a series of Municipal Preferred as to which
notice has been given as set forth in subparagraph (c) of this paragraph 4 (or
such later time or date, or both, as may be agreed to by the Auction Agent),
the Trust shall deliver to the Auction Agent either:

            (i) a notice ("Notice of Special Rate Period") stating (A) that the
      Trust has determined to designate the next succeeding Rate Period of
      shares of such series as a Special Rate Period, specifying the same and
      the first day thereof, (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) an Auction for shares of such series shall not
      be held on such Auction Date for any reason or (2) an Auction for shares
      of such series shall be held on such Auction Date but Sufficient Clearing
      Bids for shares of such series shall not exist in such Auction, (D) the
      scheduled Dividend Payment Dates for shares of such series during such
      Special Rate Period and (E) the Special Redemption Provisions, if any,
      applicable to shares of such series in respect of such Special Rate
      Period; such notice to be accompanied by a Municipal Preferred Basic
      Maintenance Report showing that, as of the third Business Day next
      preceding such proposed Special Rate Period, Moody's Eligible Assets (if
      Moody's is then rating such series) and S&P Eligible Assets (if S&P is
      then rating such series) each have an aggregate Discounted Value at least
      equal to the Municipal Preferred Basic Maintenance Amount as of such
      Business Day (assuming for purposes of the foregoing calculation that (a)
      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 (b) the Moody's Discount Factors applicable to Moody's Eligible
      Assets are determined by reference to the first Exposure Period longer
      than the Exposure Period then applicable to the Trust, as described in
      the definition of Moody's Discount Factor herein); or

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

     (e) FAILURE TO DELIVER NOTICE OF SPECIAL RATE PERIOD. If the Trust fails
to deliver either of the notices described in subparagraphs (d)(i) or (d)(ii)
of this paragraph 4 (and, in the case of the notice described in subparagraph
(d)(i) of this paragraph 4, a Municipal Preferred Basic Maintenance Report to
the effect set forth in such subparagraph (if either Moody's or S&P is then
rating the series in question)) 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 (or by such later time or date, or both, as may be agreed to by the
Auction Agent), the Trust 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 subparagraph (d)(ii) of this paragraph 4. In the event the Trust delivers to
the Auction Agent a notice described in subparagraph (d)(i) of this paragraph
4, it shall file a copy of such notice with the Secretary of the Trust, and the
contents of such notice shall be binding on the Trust. In the event the Trust
delivers to the Auction Agent a notice described in subparagraph (d)(ii) of
this paragraph 4, the Trust will provide Moody's (if Moody's is then rating the

<PAGE>

series in question) and S&P (if S&P is then rating the series in question) a
copy of such notice.

     5. VOTING RIGHTS.

     (a) ONE VOTE PER SHARE OF MUNICIPAL PREFERRED. Except as otherwise
provided in the Declaration, this paragraph 5 or as otherwise required by law,
(i) each Holder of shares of Municipal Preferred shall be entitled to one vote
for each share of Municipal Preferred held by such Holder on each matter
submitted to a vote of shareholders of the Trust, and (ii) the holders of
outstanding Preferred Shares, including each share of Municipal Preferred, and
of Common Shares shall vote together as a single class; provided, however,
that, at any meeting of the shareholders of the Trust held for the election of
trustees, the holders of outstanding Preferred Shares, including Municipal
Preferred, represented in person or by proxy at said meeting, shall be
entitled, as a class, to the exclusion of the holders of all other securities
and classes of shares of beneficial interest of the Trust, to elect two
trustees of the Trust, each Preferred Share, including each share of Municipal
Preferred, entitling the holder thereof to one vote. Subject to subparagraph
(b) of this paragraph 5, the holders of outstanding Common Shares and Preferred
Shares, including Municipal Preferred, voting together as a single class, shall
elect the balance of the trustees.

     (b) VOTING FOR ADDITIONAL TRUSTEES.

            (i) VOTING PERIOD. During any period in which any one or more of
      the conditions described in subparagraphs (A) or (B) of this subparagraph
      (b)(i) shall exist (such period being referred to herein as a "Voting
      Period"), the number of trustees constituting the Board of Trustees shall
      be automatically increased by the smallest number that, when added to the
      two trustees elected exclusively by the holders of Preferred Shares,
      including shares of Municipal Preferred, would constitute a majority of
      the Board of Trustees as so increased by such smallest number; and the
      holders of Preferred Shares, including Municipal Preferred, shall be
      entitled, voting as a class on a one-vote-per-share basis (to the
      exclusion of the holders of all other securities and classes of shares of
      beneficial interest of the Trust), to elect such smallest number of
      additional trustees, together with the two trustees that such holders are
      in any event entitled to elect. A Voting Period shall commence:

                  (A) if at the close of business on any dividend payment date
            accumulated dividends (whether or not earned or declared) on any
            outstanding Preferred Share, including Municipal Preferred, equal
            to at least two full years' dividends shall be due and unpaid and
            sufficient cash or specified securities shall not have been
            deposited with the Auction Agent for the payment of such
            accumulated dividends; or

                  (B) if at any time holders of Preferred Shares are entitled
            under the 1940 Act to elect a majority of the trustees of the
            Trust.

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


<PAGE>

            (ii) NOTICE OF SPECIAL MEETING. As soon as practicable after the
      accrual of any right of the holders of Preferred Shares to elect
      additional trustees as described in subparagraph (b)(i) of this paragraph
      5, the Trust shall notify the Auction Agent and the Auction 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
      nor more than 20 days after the date of mailing of such notice. If the
      Trust fails to send such notice to the Auction Agent or if the Auction
      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 of
      holders of Preferred Shares held during a Voting Period at which trustees
      are to be elected, such holders, voting together as a class (to the
      exclusion of the holders of all other securities and classes of shares of
      beneficial interest of the Trust), shall be entitled to elect the number
      of trustees prescribed in subparagraph (b)(i) of this paragraph 5 on a
      one-vote-per-share basis.

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

            (iv) TERMS OF OFFICE OF CERTAIN TRUSTEES TO TERMINATE UPON
      TERMINATION OF VOTING PERIOD. Simultaneously with the termination of a
      Voting Period, the term of office of the additional trustees elected by
      the Holders and holders of other Preferred Shares pursuant to
      subparagraph (b)(i) of this paragraph 5 shall terminate, the remaining
      trustees shall constitute the trustees of the Trust and the voting rights
      of the Holders and such other holders to elect additional trustees
      pursuant to subparagraph (b)(i) of this paragraph 5 shall cease, subject
      to the provisions of the last sentence of subparagraph (b)(i) of this
      paragraph 5.

     (c) HOLDERS OF MUNICIPAL PREFERRED TO VOTE ON CERTAIN OTHER MATTERS.

            (i) INCREASES IN CAPITALIZATION. So long as any shares of Municipal
      Preferred are outstanding, the Trust shall not, without the affirmative
      vote or consent of the Holders of at least a majority of the shares of
      Municipal Preferred outstanding at the time, in person or by proxy,
      either in writing or at a meeting, voting as a separate class: (a)
      authorize, create or issue any class or series of shares ranking prior to
      or on a parity with shares of Municipal Preferred with respect to the
      payment of dividends or the distribution of assets upon dissolution,
      liquidation or winding up of the affairs of the Trust, or authorize,
      create or issue additional shares of any series of Municipal Preferred

<PAGE>

      (except that, notwithstanding the foregoing, but subject to the
      provisions of paragraph 10(c) of this Part I, the Board of Trustees,
      without the vote or consent of the Holders of Municipal Preferred, may
      from time to time authorize and create, and the Trust may from time to
      time issue, additional shares of any series of Municipal Preferred or
      classes or series of Preferred Shares ranking on a parity with shares of
      Municipal Preferred with respect to the payment of dividends and the
      distribution of assets upon dissolution, liquidation or winding up of the
      affairs of the Trust; provided, however, that if Moody's or S&P is not
      then rating the shares of Municipal Preferred, the aggregate liquidation
      preference of all Preferred Shares of the Trust outstanding after any
      such issuance, exclusive of accumulated and unpaid dividends, may not
      exceed $[__________]) or (b) amend, alter or repeal the provisions of the
      Declaration, the By-laws, or this Statement, whether by merger,
      consolidation or otherwise, so as to materially affect any preference,
      right or power of such shares of Municipal Preferred or the Holders
      thereof; provided, however, that (i) none of the actions permitted by the
      exception to (a) above will be deemed to affect such preferences, rights
      or powers, (ii) a division of a share of Municipal Preferred will be
      deemed to affect such preferences, rights or powers only if the terms of
      such division adversely affect the Holders of shares of Municipal
      Preferred and (iii) the authorization, creation and issuance of classes
      or series of shares ranking junior to shares of Municipal Preferred with
      respect to the payment of dividends and the distribution of assets upon
      dissolution, liquidation or winding up of the affairs of the Trust, will
      be deemed to affect such preferences, rights or powers only if Moody's or
      S&P is then rating shares of Municipal Preferred and such issuance would,
      at the time thereof, cause the Trust not to satisfy the 1940 Act
      Municipal Preferred Asset Coverage or the Municipal Preferred Basic
      Maintenance Amount. So long as any shares of Municipal Preferred are
      outstanding, the Trust shall not, without the affirmative vote or consent
      of the Holders of at least 66 2/3% of the shares of Municipal Preferred
      outstanding at the time, in person or by proxy, either in writing or at a
      meeting, voting as a separate class, file a voluntary application for
      relief under Federal bankruptcy law or any similar application under
      state law for so long as the Trust is solvent and does not foresee
      becoming insolvent. If any action set forth above would adversely affect
      the rights of one or more series (the "Affected Series") of Municipal
      Preferred in a manner different from any other series of Municipal
      Preferred, the Trust will not approve any such action without the
      affirmative vote or consent of the Holders of at least a majority of the
      shares of each such Affected Series outstanding at the time, in person or
      by proxy, either in writing or at a meeting (each such Affected Series
      voting at a separate class).

            (ii) 1940 ACT MATTERS. Unless a higher percentage is provided for
      in the Declaration or this Statement, (A) the affirmative vote of the
      Holders of at least a majority of the Preferred Shares, including
      Municipal Preferred, outstanding at the time, voting as a separate class,
      shall be required to approve any conversion of the Trust from a
      closed-end to an open-end investment company and (B) the affirmative vote
      of the Holders of a "majority of the outstanding Preferred Shares,"
      including Municipal Preferred, 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. The affirmative vote of
      the Holders of a "majority of the outstanding Preferred Shares,"
      including Municipal Preferred, voting as a separate class, shall be
      required to approve any action not described in the first sentence of
      this paragraph 5(c)(ii) requiring a vote of security holders of the Trust
      under Section 13(a) of the 1940 Act. For purposes of the foregoing,
      "majority of the outstanding Preferred Shares" means (i) 67% or more of
      such shares present at a meeting, if the Holders of more than 50% of such
      shares are present or represented by proxy, or (ii) more than 50% of such
      shares, whichever is less. In the event a vote of Holders of Municipal
      Preferred is required pursuant to the provisions of Section 13(a) of the
      1940 Act, the Trust shall, not later than ten Business Days prior to the
      date on which such vote is to be taken, notify Moody's (if Moody's is

<PAGE>

      then rating the shares of Municipal Preferred) and S&P (if S&P is then
      rating the shares of Municipal Preferred) that such vote is to be taken
      and the nature of the action with respect to which such vote is to be
      taken. The Trust shall, not later than ten Business Days after the date
      on which such vote is taken, notify Moody's (if Moody's is then rating
      the shares of Municipal Preferred) and S&P (if S&P is then rating the
      shares of Municipal Preferred) of the results of such vote.

     (d) BOARD MAY TAKE CERTAIN ACTIONS WITHOUT SHAREHOLDER APPROVAL. The Board
of Trustees, without the vote or consent of the shareholders of the Trust, may
from time to time amend, alter or repeal any or all of the definitions of the
terms listed below, or any provision of this Statement viewed by Moody's or S&P
as a predicate for any such definition, and any such amendment, alteration or
repeal will not be deemed to affect the preferences, rights or powers of shares
of Municipal Preferred or the Holders thereof; provided, however, that the
Board of Trustees receives written confirmation from Moody's (such confirmation
being required to be obtained only in the event Moody's is rating the shares of
Municipal Preferred and in no event being required to be obtained in the case
of the definitions of (x) Deposit Securities, Discounted Value, Receivables for
Municipal Obligations Sold and Other Issues as such terms apply to S&P Eligible
Asset and (y) S&P Discount Factor, S&P Eligible Asset, S&P Exposure Period, S&P
Volatility Factor) and S&P (such confirmation being required to be obtained
only in the event S&P is rating the shares of Municipal Preferred and in no
event being required to be obtained in the case of the definitions of (x)
Discounted Value, Receivables for Municipal Obligations Sold and Other Issues
as such terms apply to Moody's Eligible Asset, and (y) Moody's Discount Factor,
Moody's Eligible Asset, Moody's Exposure Period and Moody's Volatility Factor)
that any such amendment, alteration or repeal would not impair the ratings then
assigned by Moody's or S&P, as the case may be, to shares of Municipal
Preferred:

     Discounted Value              Market Value

     (e) VOTING RIGHTS SET FORTH HEREIN ARE SOLE VOTING RIGHTS. Unless
otherwise required by law, the By-laws, this Statement or by the Declaration,
the Holders of shares of Municipal Preferred shall not have any relative rights
or preferences or other special rights other than those specifically set forth
herein.

     (f) NO PREEMPTIVE RIGHTS OR CUMULATIVE VOTING. The Holders of shares of
Municipal Preferred shall have no preemptive rights or rights to cumulative
voting.

     (g) VOTING FOR TRUSTEES SOLE REMEDY FOR TRUST'S FAILURE TO PAY DIVIDENDS.
In the event that the Trust fails to pay any dividends on the shares of
Municipal Preferred, the exclusive remedy of the Holders shall be the right to
vote for Trustees pursuant to the provisions of this paragraph 5.

     (h) HOLDERS ENTITLED TO VOTE. For purposes of determining any rights of
the Holders to vote on any matter, whether such right is created by the
By-laws, this Statement, by the other provisions of this Statement or the
Declaration, by statute or otherwise, no Holder shall be entitled to vote any
share of Municipal Preferred and no share of Municipal Preferred 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 requisite Notice of Redemption
with respect to such shares shall have been mailed as provided in paragraph
11(c) of this Part I and the Redemption Price for the redemption of such shares
shall have been deposited in trust with the Auction Agent for that purpose. No
shares of Municipal Preferred held by the Trust or any affiliate of the Trust
(except for shares held by a Broker-Dealer that is an affiliate of the Trust
for the account of its customers) shall have any voting rights or be deemed to
be outstanding for voting or other purposes.

     6. 1940 ACT MUNICIPAL PREFERRED ASSET COVERAGE.

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

     7. MUNICIPAL PREFERRED BASIC MAINTENANCE AMOUNT.

     (a) So long as shares of Municipal Preferred are outstanding, the Trust
shall maintain, on each Valuation Date, and shall verify to its satisfaction
that it is maintaining on such Valuation Date, (i) S&P Eligible Assets having
an aggregate Discounted Value equal to or greater than the Municipal Preferred
Basic Maintenance Amount (if S&P is then rating the shares of Municipal
Preferred) and (ii) Moody's Eligible Assets having an aggregate Discounted
Value equal to or greater than the Municipal Preferred Basic Maintenance Amount
(if Moody's is then rating the shares of Municipal Preferred).

     (b) On or before 5:00 P.M., New York City time, on the third Business Day
after a Valuation Date on which the Trust fails to satisfy the Municipal
Preferred Basic Maintenance Amount, and on the third Business Day after the
Municipal Preferred Basic Maintenance Cure Date with respect to such Valuation
Date, the Trust shall complete and deliver to S&P (if S&P is then rating the
shares of Municipal Preferred), Moody's (if Moody's is then rating the shares

<PAGE>

of Municipal Preferred) and the Auction Agent (if either S&P or Moody's is then
rating the shares of Municipal Preferred) a Municipal Preferred Basic
Maintenance Report as of the date of such failure or such Municipal Preferred
Basic Maintenance Cure Date, as the case may be, which will be deemed to have
been delivered to the Auction Agent if the Auction Agent receives a copy of
telecopy, telex or other electronic transcription thereof and on the same day
the Trust mails to the Auction Agent for delivery on the next Business Day the
full Municipal Preferred Basic Maintenance Report.

     The Trust shall also deliver a Municipal Preferred Basic Maintenance
Report to (i) the Auction Agent (if either Moody's or S&P is then rating the
shares of Municipal Preferred) as of (A) the fifteenth day of each month (or,
if such day is not a Business Day, the next succeeding Business Day) and (B)
the last Business Day of each month, (ii) Moody's (if Moody's is then rating
the shares of Municipal Preferred) and S&P (if S&P is then rating the shares of
Municipal Preferred) as of any Quarterly Valuation Date, in each case on or
before the third Business Day after such day, and (iii) S&P, if and when
requested for any Valuation Date, on or before the third Business Day after
such request. A failure by the Trust to deliver a Municipal Preferred Basic
Maintenance Report pursuant to the preceding sentence shall be deemed to be
delivery of a Municipal Preferred Basic Maintenance Report indicating the
Discounted Value for all assets of the Trust is less than the Municipal
Preferred Basic Maintenance Amount, as of the relevant Valuation Date.

     (c) Within ten Business Days after the date of delivery of a Municipal
Preferred Basic Maintenance Report in accordance with subparagraph (b) of this
paragraph 7 relating to a Quarterly Valuation Date, the Trust shall cause the
Independent Accountant to confirm in writing to S&P (if S&P is then rating the
shares of Municipal Preferred), Moody's (if Moody's is then rating the shares
of Municipal Preferred) and the Auction Agent (if either S&P or Moody's is then
rating the shares of Municipal Preferred) (i) the mathematical accuracy of the
calculations reflected in such Report (and in any other Municipal Preferred
Basic Maintenance Report, randomly selected by the Independent Accountant, that
was delivered by the Trust during the quarter ending on such Quarterly
Valuation Date) and (ii) that, in such Report (and in such randomly selected
Report), the Trust determined in accordance with this paragraph whether the
Trust had, at such Quarterly Valuation Date (and at the Valuation Date
addressed in such randomly-selected Report), S&P Eligible Assets (if S&P is
then rating the shares of Municipal Preferred) of an aggregate Discounted Value
at least equal to the Municipal Preferred Basic Maintenance Amount and Moody's
Eligible Assets (if Moody's is then rating the shares of Municipal Preferred)
of an aggregate Discounted Value at least equal to the Municipal Preferred
Basic Maintenance Amount (such confirmation being herein called the
"Accountant's Confirmation").

     (d) Within ten Business Days after the date of delivery of a Municipal
Preferred Basic Maintenance Report in accordance with subparagraph (b) of this
paragraph 7 relating to any Valuation Date on which the Trust failed to satisfy
the Municipal Preferred Basic Maintenance Amount, and relating to the Municipal
Preferred Basic Maintenance Cure Date with respect to such failure to satisfy
the Municipal Preferred Basic Maintenance Amount, the Trust shall cause the
Independent Accountant to provide to S&P (if S&P is then rating the shares of
Municipal Preferred), Moody's (if Moody's is then rating the shares of
Municipal Preferred) and the Auction Agent (if either S&P or Moody's is then
rating the shares of Municipal Preferred) an Accountant's Confirmation as to
such Municipal Preferred Basic Maintenance Report.

     (e) If any Accountant's Confirmation delivered pursuant to subparagraph
(c) or (d) of this paragraph 7 shows that an error was made in the Municipal

<PAGE>

Preferred Basic Maintenance Report for a particular Valuation Date for which
such Accountant's Confirmation was required to be delivered, or shows that a
lower aggregate Discounted Value for the aggregate of all S&P Eligible Assets
(if S&P is then rating the shares of Municipal Preferred) or Moody's Eligible
Assets (if Moody's is then rating the shares of Municipal Preferred), as the
case may be, of the Trust was determined by the Independent Accountant, the
calculation or determination made by such Independent Accountant shall be final
and conclusive and shall be binding on the Trust, and the Trust shall
accordingly amend and deliver the Municipal Preferred Basic Maintenance Report
to S&P (if S&P is then rating the shares of Municipal Preferred), Moody's (if
Moody's is then rating the shares of Municipal Preferred) and the Auction Agent
(if either S&P or Moody's is then rating the shares of Municipal Preferred)
promptly following receipt by the Trust of such Accountant's Confirmation.

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

     (g) On or before 5:00 p.m., New York City time, on the third Business Day
after either (i) the Trust shall have redeemed Common Shares or (ii) the ratio
of the Discounted Value of S&P Eligible Assets or the Discounted Value of
Moody's Eligible Assets to the Municipal Preferred Basic Maintenance Amount is
less than or equal to 105%, the Trust shall complete and deliver to S&P (if S&P
is then rating the shares of Municipal Preferred) or Moody's (if Moody's is
then rating the shares of Municipal Preferred), as the case may be, a Municipal
Preferred Basic Maintenance Report as of the date of either such event.

     8. [RESERVED].

     9. RESTRICTIONS ON DIVIDENDS AND OTHER DISTRIBUTIONS.

     (a) DIVIDENDS ON PREFERRED SHARES OTHER THAN MUNICIPAL PREFERRED. 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 shares of
beneficial interest of the Trust ranking, as to the payment of dividends, on a
parity with shares of Municipal Preferred for any period unless full cumulative
dividends have been or contemporaneously are declared and paid on the shares of
each series of Municipal Preferred through its most recent Dividend Payment
Date. When dividends are not paid in full upon the shares of each series of
Municipal Preferred through its most recent Dividend Payment Date or upon the
shares of any other class or series of shares of beneficial interest of the
Trust ranking on a parity as to the payment of dividends with shares of
Municipal Preferred through their most recent respective dividend payment
dates, all dividends declared upon shares of Municipal Preferred and any other
such class or series of shares of beneficial interest ranking on a parity as to
the payment of dividends with shares of Municipal Preferred shall be declared
pro rata so that the amount of dividends declared per share on shares of
Municipal Preferred and such other class or series of shares of beneficial
interest shall in all cases bear to each other the same ratio that accumulated
dividends per share on the shares of Municipal Preferred and such other class
or series of shares of beneficial interest bear to each other (for purposes of
this sentence, the amount of dividends declared per share of Municipal
Preferred shall be based on the Applicable Rate for such shares for the
Dividend Periods during which dividends were not paid in full).

     (b) DIVIDENDS AND OTHER DISTRIBUTIONS WITH RESPECT TO COMMON SHARES UNDER
THE 1940 ACT. The Board of Trustees shall not declare any dividend (except a
dividend payable in Common Shares), or declare any other distribution, upon the
Common Shares, or purchase Common Shares, unless in every such case the
Preferred Shares have, at the time of any such declaration or purchase, an
asset coverage (as defined in and determined pursuant to the 1940 Act) of at
least 200% (or such other asset coverage as may in the future be specified in
or under the 1940 Act as the minimum asset coverage for senior securities which
are shares or stock of a closed-end investment company as a condition of
declaring dividends on its common shares or stock) after deducting the amount
of such dividend, distribution or purchase price, as the case may be.

     (c) OTHER RESTRICTIONS ON DIVIDENDS AND OTHER DISTRIBUTIONS. For so long
as any share of Municipal Preferred is outstanding, and except as set forth in
subparagraph (a) of this paragraph 9 and paragraph 12(c) of this Part I, (A)
the Trust shall not declare, pay or set apart for payment any dividend or other
distribution (other than a dividend or distribution paid in shares of, or in
options, warrants or rights to subscribe for or purchase, Common Shares or
other shares, if any, ranking junior to the shares of Municipal Preferred as to
the payment of dividends and the distribution of assets upon dissolution,
liquidation or winding up) in respect of the Common Shares or any other shares
of the Trust ranking junior to or on a parity with the shares of Municipal
Preferred as to the payment of dividends or the distribution of assets upon
dissolution, liquidation or winding up, or call for redemption, redeem,
purchase or otherwise acquire for consideration any Common Shares or any other
such junior shares (except by conversion into or exchange for shares of the

<PAGE>

Trust ranking junior to the shares of Municipal Preferred as to the payment of
dividends and the distribution of assets upon dissolution, liquidation or
winding up), or any such parity shares (except by conversion into or exchange
for shares of the Trust ranking junior to or on a parity with Municipal
Preferred as to the payment of dividends and the distribution of assets upon
dissolution, liquidation or winding up), unless (i) full cumulative dividends
on shares of each series of Municipal Preferred through its most recently ended
Dividend Period shall have been paid or shall have been declared and sufficient
funds for the payment thereof deposited with the Auction Agent and (ii) the
Trust has redeemed the full number of shares of Municipal Preferred required to
be redeemed by any provision for mandatory redemption pertaining thereto, and
(B) the Trust shall not declare, pay or set apart for payment any dividend or
other distribution (other than a dividend or distribution paid in shares of, or
in options, warrants or rights to subscribe for or purchase, Common Shares or
other shares, if any, ranking junior to shares of Municipal Preferred as to the
payment of dividends and the distribution of assets upon dissolution,
liquidation or winding up) in respect of Common Shares or any other shares of
the Trust ranking junior to shares of Municipal Preferred as to the payment of
dividends or the distribution of assets upon dissolution, liquidation or
winding up, or call for redemption, redeem, purchase or otherwise acquire for
consideration any Common Shares or any other such junior shares (except by
conversion into or exchange for shares of the Trust ranking junior to shares of
Municipal Preferred as to the payment of dividends and the distribution of
assets upon dissolution, liquidation or winding up), unless immediately after
such transaction the Discounted Value of Moody's Eligible Assets (if Moody's is
then rating the shares of Municipal Preferred) and S&P Eligible Assets (if S&P
is then rating the shares of Municipal Preferred) would each at least equal the
Municipal Preferred Basic Maintenance Amount.

     10. RATING AGENCY RESTRICTIONS.

     For so long as any shares of Municipal Preferred are outstanding and
Moody's or S&P, or both, are rating such shares, the Trust will not, unless it
has received written confirmation from Moody's or S&P, or both, as appropriate,
that any such action would not impair the ratings then assigned by such rating
agency to such shares, engage in any one or more of the following transactions:

     (a) purchase or sell futures contracts, write, purchase or sell options on
futures contracts or write put options (except covered put options) or call
options (except covered call options) on portfolio securities except that the
Trust 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 put and call options on such
contracts (collectively, "Hedging Transactions"), subject to the following
limitations:

            (i) the Trust will not engage in any Hedging Transaction based on
      the Municipal Index (other than transactions which terminate a futures
      contract or option held by the Trust by the Trust's taking an opposite
      position thereto ("Closing Transactions")), which would cause the Trust
      at the time of such transaction to own or have sold the least of (A) more
      than 1,000 outstanding futures contracts based on the Municipal Index,
      (B) outstanding futures contracts based on the Municipal Index exceeding
      in number 25% of the quotient of the Market Value of the Trust's total
      assets divided by $1,000 or (C) outstanding futures contracts based on
      the Municipal Index exceeding in number 10% of the average number of
      daily open interest futures contracts based on the Municipal Index in the
      30 days preceding the time of effecting such transaction as reported by
      The Wall Street Journal;


<PAGE>

            (ii) the Trust will not engage in any Hedging Transaction based on
      Treasury Bonds (other than Closing Transactions) which would cause the
      Trust 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% of the quotient of the Market Value of the Trust'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% 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 Trust will engage in Closing Transactions to close out
      any outstanding futures contract which the Trust owns or has sold or any
      outstanding option thereon owned by the Trust in the event (A) the Trust
      does not have S&P Eligible Assets or Moody's Eligible Assets, as the case
      may be, with an aggregate Discounted Value equal to or greater than the
      Municipal Preferred Basic Maintenance Amount on two consecutive Valuation
      Dates and (B) the Trust is required to pay Variation Margin on the second
      such Valuation Date;

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

            (v) when the Trust writes a futures contract or option thereon, it
      will either maintain an amount of cash, cash equivalents or high grade
      (rated A or better by S&P or Moody's, as the case may be), fixed-income
      securities in a segregated account with the Trust's custodian, so that
      the amount so segregated plus the amount of Initial Margin and Variation
      Margin held in the account of or on behalf of the Trust'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 Trust writes a futures
      contract or option thereon which requires delivery of an underlying
      security, it shall hold such underlying security in its portfolio.

     For purposes of determining whether the Trust has S&P Eligible Assets or
Moody's Eligible Assets, as the case may be, with a Discounted Value that
equals or exceeds the Municipal Preferred Basic Maintenance Amount, the
Discounted Value of cash or securities held for the payment of Initial Margin
or Variation Margin shall be zero and the aggregate Discounted Value of S&P
Eligible Assets or Moody's Eligible Assets, as the case may be, shall be
reduced by an amount equal to (I) 30% of the aggregate settlement value, as
marked to market, of any outstanding futures contracts based on the Municipal
Index which are owned by the Trust plus (II) 25% of the aggregate settlement
value, as marked to market, of any outstanding futures contracts based on
Treasury Bonds which contracts are owned by the Trust;

     (b) borrow money, except that the Trust may, without obtaining the written
confirmation described above, borrow money for the purpose of clearing
securities transactions if (i) the Municipal Preferred Basic Maintenance Amount
would continue to be satisfied after giving effect to such borrowing (which
shall mean, for purposes of the calculation of the Municipal Preferred Basic
Maintenance Amount, adding the amount of the liability for such borrowing to
the calculation of the Municipal Preferred Basic Maintenance Amount under
subparagraph (F) under the definition of that term in Part I of this Statement)
and (ii) such borrowing (A) 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 (B) is for "temporary purposes," is

<PAGE>

evidenced by a promissory note or other evidence of indebtedness and is an
amount not exceeding 5 per centum of the value of the total assets of the Trust
at the time of the borrowing; for purposes of the foregoing, "temporary
purposes" means that the borrowing is to be repaid within sixty days and is not
to be extended or renewed;

     (c) issue additional shares of any series of Municipal Preferred or any
class or series of shares ranking prior to or on a parity with shares of
Municipal Preferred with respect to the payment of dividends or the
distribution of assets upon dissolution, liquidation or winding up of the
Trust, or reissue any shares of Municipal Preferred previously purchased or
redeemed by the Trust;

     (d) engage in any short sales of securities;

     (e) lend securities;

     (f) merge or consolidate into or with any corporation;

     (g) change the pricing service (currently both Muller Data Corporation and
Standard & Poor's J.J. Kenny Evaluation Services are used by the Trust)
referred to in the definition of Market Value to a pricing service other than
Muller Data Corporation or Standard & Poor's J.J. Kenny Evaluation Services; or

     (h) enter into reverse repurchase agreements.

     11. REDEMPTION.

     (a) OPTIONAL REDEMPTION.

            (i) Subject to the provisions of subparagraph (v) of this
      subparagraph (a), shares of Municipal Preferred of any series may be
      redeemed, at the option of the Trust, as a whole or from time to time in
      part, on the second Business Day preceding any Dividend Payment Date for
      shares of such series, out of funds legally available therefor, at a
      redemption price per share equal to the sum of $25,000 plus an amount
      equal to accumulated but unpaid dividends thereon (whether or not earned
      or declared) to (but not including) the date fixed for redemption;
      provided, however, that (1) shares of a series of Municipal Preferred may
      not be redeemed in part if after such partial redemption fewer than 500
      shares of such series remain outstanding; (2) unless otherwise provided
      herein, shares of a series of Municipal Preferred are redeemable by the
      Trust during the Initial Rate Period thereof only on the second Business
      Day next preceding the last Dividend Payment Date for such Initial Rate
      Period; and (3) subject to subparagraph (ii) of this paragraph, (a) the
      Notice of Special Rate Period relating to a Special Rate Period of shares
      of a series of Municipal Preferred, as delivered to the Auction Agent and
      filed with the Secretary of the Trust, may provide that shares of such
      series shall not be redeemable during the whole or any part of such
      Special Rate Period (except as provided in subparagraph (iv) of this
      subparagraph (a)) or shall be redeemable during the whole or any part of
      such Special Rate Period only upon payment of such redemption premium or
      premiums as shall be specified therein ("Special Redemption Provisions").


<PAGE>

            (ii) A Notice of Special Rate Period relating to shares of a series
      of Municipal Preferred for a Special Rate Period thereof may contain
      Special Redemption Provisions only if the Trust's Board of Trustees,
      after consultation with the Broker-Dealer or Broker-Dealers for such
      Special Rate Period of shares of such series, determines that such
      Special Redemption Provisions are in the best interest of the Trust.

            (iii) If fewer than all of the outstanding shares of a series of
      Municipal Preferred are to be redeemed pursuant to subparagraph (i) of
      this subparagraph (a), the number of shares of such series to be redeemed
      shall be determined by the Board of Trustees, and such shares shall be
      redeemed pro rata from the Holders of shares of such series in proportion
      to the number of shares of such series held by such Holders.

            (iv) Subject to the provisions of subparagraph (v) of this
      subparagraph (a), shares of any series of Municipal Preferred may be
      redeemed, at the option of the Trust, as a whole but not in part, out of
      funds legally available therefor, on the first day following any Dividend
      Period thereof included in a Rate Period consisting of more than 364 Rate
      Period Days if, on the date of determination of the Applicable Rate for
      shares of such series for such Rate Period, such Applicable Rate equaled
      or exceeded on such date of determination the Treasury Note Rate for such
      Rate Period, at a redemption price per share equal to the sum of $25,000
      plus an amount equal to accumulated but unpaid dividends thereon (whether
      or not earned or declared) to (but not including) to the date fixed for
      redemption.

            (v) The Trust may not on any date mail a Notice of Redemption
      pursuant to subparagraph (c) of this paragraph 11 in respect of a
      redemption contemplated to be effected pursuant to this subparagraph (a)
      unless on such date (a) the Trust has available Deposit Securities with
      maturity or tender dates not later than the day preceding the applicable
      redemption date and having a value not less than the amount (including
      any applicable premium) due to Holders of shares of Municipal Preferred
      by reason of the redemption of such shares on such redemption date and
      (b) the Discounted Value of Moody's Eligible Assets (if Moody's is then
      rating the shares of Municipal Preferred) and the Discounted Value of S&P
      Eligible Assets (if S&P is then rating the shares of Municipal Preferred)
      each at least equal the Municipal Preferred Basic Maintenance Amount, and
      would at least equal the Municipal Preferred Basic Maintenance Amount
      immediately subsequent to such redemption if such redemption were to
      occur on such date. For purposes of determining in clause (b) of the
      preceding sentence whether the Discounted Value of Moody's Eligible
      Assets at least equals the Municipal Preferred Basic Maintenance Amount,
      the Moody's Discount Factors applicable to Moody's Eligible Assets shall
      be determined by reference to the first Exposure Period longer than the
      Exposure Period then applicable to the Trust, as described in the
      definition of Moody's Discount Factor herein.

     (b) MANDATORY REDEMPTION. The Trust shall redeem, at a redemption price
equal to $25,000 per share plus accumulated but unpaid dividends thereon
(whether or not earned or declared) to (but not including) the date fixed by
the Board of Trustees for redemption, certain of the shares of Municipal
Preferred, if the Trust fails to have either Moody's Eligible Assets with a
Discounted Value, or S&P Eligible Assets with a Discounted Value, greater than

<PAGE>

or equal to the Municipal Preferred Basic Maintenance Amount or fails to
maintain the 1940 Act Municipal Preferred Asset Coverage, in accordance with
the requirements of the rating agency or agencies then rating the shares of
Municipal Preferred, and such failure is not cured on or before the Municipal
Preferred Basic Maintenance Cure Date or the 1940 Act Cure Date, as the case
may be (the "Cure Date"). The number of shares of Municipal Preferred to be
redeemed shall be equal to the lesser of (i) the minimum number of shares of
Municipal Preferred, together with all other Preferred Shares subject to
redemption or retirement, the redemption of which, if deemed to have occurred
immediately prior to the opening of business on the Cure Date, would have
resulted in the Trust's having both Moody's Eligible Assets with a Discounted
Value, and S&P Eligible Assets with a Discounted Value, greater than or equal
to the Municipal Preferred Basic Maintenance Amount or maintaining the 1940 Act
Municipal Preferred Asset Coverage, as the case may be, on such Cure Date
(provided, however, that if there is no such minimum number of shares of
Municipal Preferred and other Preferred Shares the redemption or retirement of
which would have had such result, all shares of Municipal Preferred and
Preferred Shares then outstanding shall be redeemed), and (ii) the maximum
number of shares of Municipal Preferred, together with all other Preferred
Shares subject to redemption or retirement, that can be redeemed out of funds
expected to be legally available therefor in accordance with the Declaration,
the By-laws, this Statement and applicable law. In determining the shares of
Municipal Preferred required to be redeemed in accordance with the foregoing,
the Trust shall allocate the number required to be redeemed to satisfy the
Municipal Preferred Basic Maintenance Amount or the 1940 Act Municipal
Preferred Asset Coverage, as the case may be, pro rata among shares of
Municipal Preferred and other Preferred Shares (and, then pro rata among each
series of Municipal Preferred) subject to redemption or retirement. The Trust
shall effect such redemption on the date fixed by the Trust therefor, which
date shall not be earlier than 20 days nor later than 40 days after such Cure
Date, except that if the Trust does not have funds legally available for the
redemption of all of the required number of shares of Municipal Preferred and
other Preferred Shares which are subject to redemption or retirement or the
Trust otherwise is unable to effect such redemption on or prior to 40 days
after such Cure Date, the Trust shall redeem those shares of Municipal
Preferred and other Preferred Shares which it was unable to redeem on the
earliest practicable date on which it is able to effect such redemption. If
fewer than all of the outstanding shares of a series of Municipal Preferred are
to be redeemed pursuant to this subparagraph (b), the number of shares of such
series to be redeemed shall be redeemed pro rata from the Holders of shares of
such series in proportion to the number of shares of such series held by such
Holders.

     (c) NOTICE OF REDEMPTION. If the Trust shall determine or be required to
redeem shares of a series of Municipal Preferred pursuant to subparagraph (a)
or (b) of this paragraph 11, it shall mail a Notice of Redemption with respect
to such redemption by first class mail, postage prepaid, to each Holder of the
shares of such series to be redeemed, at such Holder's address as the same
appears on the record books of the Trust on the record date established by the
Board of Trustees. Such Notice of Redemption shall be so mailed not less than
20 nor more than 45 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 Municipal Preferred to be redeemed and the series thereof; (iii) the
CUSIP number for shares of such series; (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 Trustees 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; and (vii) the provisions of this
paragraph 11 under which such redemption is made. If fewer than all shares of a
series of Municipal Preferred held by any Holder are to be redeemed, the Notice
of Redemption mailed to such Holder shall also specify the number of shares of
such series to be redeemed from such Holder. The Trust may provide in any
Notice of Redemption relating to an optional redemption contemplated to be

<PAGE>

effected pursuant to subparagraph (a) of this paragraph 11 that such redemption
is subject to one or more conditions precedent and that the Trust shall not be
required to make such redemption unless each such condition shall have been
satisfied at the time or times and in the manner specified in such Notice of
Redemption.

     (d) NO REDEMPTION UNDER CERTAIN CIRCUMSTANCES. Notwithstanding the
provisions of subparagraphs (a) or (b) of this paragraph 11, if any dividends
on shares of a series of Municipal Preferred (whether or not earned or
declared) are in arrears, no shares of such series shall be redeemed unless all
outstanding shares of such series are simultaneously redeemed, and the Trust
shall not purchase or otherwise acquire any shares of such series; provided,
however, that the foregoing shall not prevent the purchase or acquisition of
all outstanding shares of such series pursuant to the successful completion of
an otherwise lawful purchase or exchange offer made on the same terms to, and
accepted by, Holders of all outstanding shares of such series.

     (e) ABSENCE OF FUNDS AVAILABLE FOR REDEMPTION. To the extent that any
redemption for which Notice of Redemption has been mailed is not made by reason
of the absence of legally available funds therefor in accordance with the
Declaration, the By-laws, this Statement and applicable law, such redemption
shall be made as soon as practicable to the extent such funds become available.
Failure to redeem shares of Municipal Preferred shall be deemed to exist at any
time after the date specified for redemption in a Notice of Redemption when the
Trust shall have failed, for any reason whatsoever, to deposit in trust with
the Auction Agent the Redemption Price with respect to any shares of which such
Notice of Redemption has been mailed; provided, however, that the foregoing
shall not apply in the case of the Trust's failure to deposit in trust with the
Auction Agent the Redemption Price with respect to any shares where (1) the
Notice of Redemption relating to such redemption provided that such redemption
was subject to one or more conditions precedent and (2) any such condition
precedent shall not have been satisfied at the time or times and in the manner
specified in such Notice of Redemption. Notwithstanding the fact that the Trust
may not have redeemed shares of Municipal Preferred for which a Notice of
Redemption has been mailed, dividends may be declared and paid on shares of
Municipal Preferred and shall include those shares of Municipal Preferred for
which a Notice of Redemption has been mailed.

     (f) AUCTION AGENT AS TRUSTEE OF REDEMPTION PAYMENTS BY TRUST. All moneys
paid to the Auction Agent for payment of the Redemption Price of shares of
Municipal Preferred called for redemption shall be held in trust by the Auction
Agent for the benefit of Holders of shares so to be redeemed.

     (g) SHARES FOR WHICH NOTICE OF REDEMPTION HAS BEEN GIVEN ARE NO LONGER
OUTSTANDING. Provided a Notice of Redemption has been mailed pursuant to
subparagraph (c) of this paragraph 11, upon the deposit with the Auction Agent
(on the Business Day next preceding the date fixed for redemption thereby, in
funds available on the next Business Day in The City of New York, New York) of
funds sufficient to redeem the shares of Municipal Preferred that are the
subject of such notice, dividends on such shares shall cease to accumulate and
such shares shall no longer be deemed to be outstanding for any purpose, and
all rights of the Holders of the shares so called for redemption shall cease

<PAGE>

and terminate, except the right of such Holders to receive the Redemption
Price, but without any interest or other additional amount, except as provided
in paragraphs 2(e)(i) and 3 of this Part I. Upon surrender in accordance with
the Notice of Redemption of the certificates for any shares so redeemed
(properly endorsed or assigned for transfer, if the Board of Trustees shall so
require and the Notice of Redemption shall so state), the Redemption Price
shall be paid by the Auction Agent to the Holders of shares of Municipal
Preferred subject to redemption. In the case that fewer than all of the shares
represented by any such certificate are redeemed, a new certificate shall be
issued, representing the unredeemed shares, without cost to the Holder thereof.
The Trust shall be entitled to receive from the Auction Agent, promptly after
the date fixed for redemption, any cash deposited with the Auction Agent in
excess of (i) the aggregate Redemption Price of the shares of Municipal
Preferred called for redemption on such date and (ii) all other amounts to
which Holders of shares of Municipal Preferred called for redemption may be
entitled. Any funds so deposited that are unclaimed at the end of 90 days from
such redemption date shall, to the extent permitted by law, be repaid to the
Trust, after which time the Holders of shares of Municipal Preferred so called
for redemption may look only to the Trust for payment of the Redemption Price
and all other amounts to which they may be entitled. The Trust shall be
entitled to receive, from time to time after the date fixed for redemption, any
interest on the funds so deposited.

     (h) COMPLIANCE WITH APPLICABLE LAW. In effecting any redemption pursuant
to this paragraph 11, the Trust shall use its best efforts to comply with all
applicable conditions precedent to effecting such redemption under the 1940 Act
and any applicable Massachusetts law, but shall effect no redemption except in
accordance with the 1940 Act and any applicable Massachusetts law.

     (i) ONLY WHOLE SHARES OF MUNICIPAL PREFERRED MAY BE REDEEMED. In the case
of any redemption pursuant to this paragraph 11, only whole shares of Municipal
Preferred shall be redeemed, and in the event that any provision of the
Declaration, the By-laws or this Statement would require redemption of a
fractional share, the Auction Agent shall be authorized to round up so that
only whole shares are redeemed.

     12. LIQUIDATION RIGHTS.

     (a) RANKING. The shares of a series of Municipal Preferred shall rank on a
parity with each other, with shares of any other series of Municipal Preferred
and with shares of any other series of Preferred Shares as to the distribution
of assets upon dissolution, liquidation or winding up of the affairs of the
Trust.

     (b) DISTRIBUTIONS UPON LIQUIDATION. Upon the dissolution, liquidation or
winding up of the affairs of the Trust, whether voluntary or involuntary, the
Holders of shares of Municipal Preferred then outstanding shall be entitled to
receive and to be paid out of the assets of the Trust available for
distribution to its shareholders, before any payment or distribution shall be
made on the Common Shares or on any other class of shares of the Trust ranking
junior to the Municipal Preferred upon dissolution, liquidation or winding up,
an amount equal to the Liquidation Preference with respect to such shares plus
an amount equal to all dividends thereon (whether or not earned or declared)
accumulated but unpaid to (but not including) the date of final distributions
in same-day funds, together with any payments required to be made pursuant to
paragraph 3 of this Part I in connection with the liquidation of the Trust.
After the payment to the Holders of the shares of Municipal Preferred of the
full preferential amounts provided for in this subparagraph (b), the holders of
Municipal Preferred as such shall have no right or claim to any of the
remaining assets of the Trust.


<PAGE>

     (c) PRO RATA DISTRIBUTIONS. In the event the assets of the Trust available
for distribution to the Holders of shares of Municipal Preferred upon any
dissolution, liquidation, or winding up of the affairs of the Trust, whether
voluntary or involuntary, shall be insufficient to pay in full all amounts to
which such Holders are entitled pursuant to subparagraph (b) of this paragraph
12, no such distribution shall be made on account of any shares of any other
class or series of Preferred Shares ranking on a parity with the shares of
Municipal Preferred 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 Municipal Preferred, ratably,
in proportion to the full distributable amounts for which holders of all such
parity shares are respectively entitled upon such dissolution, liquidation or
winding up.

     (d) RIGHTS OF JUNIOR SHARES. Subject to the rights of the holders of
shares of any series or class or classes of shares ranking on a parity with the
shares of Municipal Preferred with respect to the distribution of assets upon
dissolution, liquidation or winding up of the affairs of the Trust, after
payment shall have been made in full to the Holders of the shares of Municipal
Preferred as provided in subparagraph (b) of this paragraph 12, but not prior
thereto, any other series or class or classes of shares ranking junior to the
shares of Municipal Preferred with respect to the distribution of assets upon
dissolution, liquidation or winding up of the affairs of the Trust shall,
subject to the respective terms and provisions (if any) applying thereto, be
entitled to receive any and all assets remaining to be paid or distributed, and
the Holders of the shares of Municipal Preferred shall not be entitled to share
therein.

     (e) CERTAIN EVENTS NOT CONSTITUTING LIQUIDATION. Neither the sale of all
or substantially all of the property or business of the Trust, nor the merger
or consolidation of the Trust into or with any trust, corporation or other
entity nor the merger or consolidation of any trust, corporation or other
entity into or with the Trust shall be a dissolution, liquidation or winding
up, whether voluntary or involuntary, for the purposes of this paragraph 12.

     13. MISCELLANEOUS.

provisions of subparagraph (c) of paragraph 10 of this Part I, the Board of

                                    PART II

     1. ORDERS.

     (a) Prior to the Submission Deadline on each Auction Date for shares of a
series of Municipal Preferred:

            (i) each Beneficial Owner of shares of such series may submit to
      its Broker-Dealer by telephone or otherwise information as to:

                  (A) the number of Outstanding shares, if any, of such series
            held by such Beneficial Owner which such Beneficial Owner desires
            to continue to hold without regard to the Applicable Rate for
            shares of such series for the next succeeding Rate Period of such
            shares;

                  (B) the number of Outstanding shares, if any, of such series
            held by such Beneficial Owner which such Beneficial Owner offers to
            sell if the Applicable Rate for shares of such series for the next
            succeeding Rate Period of shares of such series shall be less than
            the rate per annum specified by such Beneficial Owner; and/or

                  (C) the number of Outstanding shares, if any, of such series
            held by such Beneficial Owner which such Beneficial Owner offers to
            sell without regard to the Applicable Rate for shares of such
            series for the next succeeding Rate Period of shares of such
            series; and

            (ii) one or more Broker-Dealers, using lists of Potential
      Beneficial Owners, shall in good faith for the purpose of conducting a
      competitive Auction in a commercially reasonable manner, contact
      Potential Beneficial Owners (by telephone or otherwise), including
      Persons that are not Beneficial Owners, on such lists to determine the

<PAGE>

      number of shares, if any, of such series which each such Potential
      Beneficial Owner offers to purchase if the Applicable Rate for shares of
      such series for the next succeeding Rate Period of shares of such series
      shall not be less than the rate per annum specified by such Potential
      Beneficial Owner.

For purposes hereof, the communication by a Beneficial Owner or Potential
Beneficial Owner to a Broker-Dealer, or by a Broker-Dealer to the Auction
Agent, of information referred to in clause (i)(A), (i)(B), (i)(C), or (ii) of
this subparagraph (a) is hereinafter referred to as an "Order" and collectively
as "Orders" and each Beneficial Owner and each Potential Beneficial Owner
placing an Order with a Broker-Dealer, and such Broker-Dealer placing an Order
with the Auction Agent, is hereinafter referred to as a "Bidder" and
collectively as "Bidders"; an Order containing the information referred to in
clause (i)(A) of this subparagraph (a) is hereinafter referred to as a "Hold
Order" and collectively as "Hold Orders"; an Order containing the information
referred to in clause (i)(B) or (ii) of this subparagraph (a) is hereinafter
referred to as a "Bid" and collectively as "Bids"; and an Order containing the
information referred to in clause (i)(C) of this subparagraph (a) is
hereinafter referred to as a "Sell Order" and collectively as "Sell Orders."

      (b) (i) A Bid by a Beneficial Owner or an Existing Holder of shares of a
      series of Municipal Preferred subject to an Auction on any Auction Date
      shall constitute an irrevocable offer to sell:

                  (A) the number of Outstanding shares of such series specified
            in such Bid if the Applicable Rate for shares of such series
            determined on such Auction Date shall be less than the rate
            specified therein;

                  (B) such number or a lesser number of Outstanding shares of
            such series to be determined as set forth in paragraph 4(a)(iv) of
            this Part II if the Applicable Rate for shares of such series
            determined on such Auction Date shall be equal to the rate
            specified therein; or

                  (C) the number of Outstanding shares of such series specified
            in such Bid if the rate specified therein shall be higher than the
            Maximum Rate for shares of such series, or such number or a lesser
            number of Outstanding shares of such series to be determined as set
            forth in paragraph 4(b)(iii) of this Part II if the rate specified
            therein shall be higher than the Maximum Rate for shares of such
            series and Sufficient Clearing Bids for shares of such series do
            not exist.

            (ii) Sell Order by a Beneficial Owner or an Existing Holder of
      shares of a series of Municipal Preferred subject to an Auction on any
      Auction Date shall constitute an irrevocable offer to sell:

                  (A) the number of Outstanding shares of such series specified
            in such Sell Order; or

                  (B) such number or a lesser number of Outstanding shares of
            such series as set forth in paragraph 4(b)(iii) of this Part II if
            Sufficient Clearing Bids for shares of such series do not exist;


<PAGE>

      provided, however, that a Broker-Dealer that is an Existing Holder with
      respect to shares of a series of Municipal Preferred shall not be liable
      to any Person for failing to sell such shares pursuant to a Sell Order
      described in the proviso to paragraph 2(c) of this Part II if (1) such
      shares were transferred by the Beneficial Owner thereof without
      compliance by such Beneficial Owner or its transferee Broker-Dealer (or
      other transferee person, if permitted by the Trust) with the provisions
      of paragraph 7 of this Part II or (2) such Broker-Dealer has informed the
      Auction Agent pursuant to the terms of its Broker-Dealer Agreement that,
      according to such Broker-Dealer's records, such Broker-Dealer believes it
      is not the Existing Holder of such shares.

            (iii) A Bid by a Potential Beneficial Holder or a Potential Holder
      of shares of a series of Municipal Preferred subject to an Auction on any
      Auction Date shall constitute an irrevocable offer to purchase:

                  (A) the number of Outstanding shares of such series specified
            in such Bid if the Applicable Rate for shares of such series
            determined on such Auction Date shall be higher than the rate
            specified therein; or

                  (B) such number or a lesser number of Outstanding shares of
            such series as set forth in paragraph 4(a)(v) of this Part II if
            the Applicable Rate for shares of such series determined on such
            Auction Date shall be equal to the rate specified therein.

     (c) No Order for any number of shares of Municipal Preferred other than
whole shares shall be valid.

     2. SUBMISSION OF ORDERS BY BROKER-DEALERS TO AUCTION AGENT.

     (a) Each Broker-Dealer shall submit in writing to the Auction Agent prior
to the Submission Deadline on each Auction Date all Orders for shares of
Municipal Preferred of a series subject to an Auction on such Auction Date
obtained by such Broker-Dealer, designating itself (unless otherwise permitted
by the Trust) as an Existing Holder in respect of shares subject to Orders
submitted or deemed submitted to it by Beneficial Owners and as a Potential
Holder in respect of shares subject to Orders submitted to it by Potential
Beneficial Owners, and shall specify with respect to each Order for such
shares:

            (i) the name of the Bidder placing such Order (which shall be the
      Broker-Dealer unless otherwise permitted by the Trust);

            (ii) the aggregate number of shares of such series that are the
      subject of such Order;

            (iii) to the extent that such Bidder is an Existing Holder of
      shares of such series:

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

                  (B) the number of shares, if any, of such series subject to
            any Bid of such Existing Holder and the rate specified in such Bid;
            and


<PAGE>

                  (C) the number of shares, if any, of such series subject to
            any Sell Order of such Existing Holder; and

            (iv) to the extent such Bidder is a Potential Holder of shares of
      such series, the rate and number of shares of such series specified in
      such Potential Holder's Bid.

     (b) If any rate specified in any Bid contains more than three figures to
the right of the decimal point, the Auction Agent shall round such rate up to
the next highest one thousandth (.001) of 1%.

     (c) If an Order or Orders covering all of the Outstanding shares of
Municipal Preferred of a series held by any Existing Holder is not submitted to
the Auction Agent prior to the Submission Deadline, the Auction Agent shall
deem a Hold Order to have been submitted by or on behalf of such Existing
Holder covering the number of Outstanding shares of such series 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 such series held by any Existing Holder is not submitted to the
Auction Agent prior to the Submission Deadline for an Auction relating to a
Special Rate Period consisting of more than 28 Rate Period Days, 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 such series 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 Municipal Preferred of a series 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 such series shall be considered
      valid, but only up to and including in the aggregate the number of
      Outstanding shares of such series held by such Existing Holder, and if
      the number of shares of such series subject to such Hold Orders exceeds
      the number of Outstanding shares of such series held by such Existing
      Holder, the number of shares subject to each such Hold Order shall be
      reduced pro rata to cover the number of Outstanding shares of such series
      held by such Existing Holder;

            (ii) (A) any Bid for shares of such series shall be considered
            valid up to and including the excess of the number of Outstanding
            shares of such series held by such Existing Holder over the number
            of shares of such series 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 for shares of such series is submitted to the
            Auction Agent with the same rate and the number of Outstanding
            shares of such series 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 such series
            subject to each Bid with the same rate shall be reduced pro rata to
            cover the number of shares of such series equal to such excess;


<PAGE>

                  (C) subject to subclauses (A) and (B), if more than one Bid
            of an Existing Holder for shares of such series 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 such series 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 such series
            by or on behalf of a Potential Holder at the rate therein
            specified; and

            (iii) all Sell Orders for shares of such series shall be considered
      valid up to and including the excess of the number of Outstanding shares
      of such series held by such Existing Holder over the sum of shares of
      such series 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 a series of Municipal
Preferred 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 therein specified.

      (f) Any Order submitted by a Beneficial Owner or a Potential Beneficial
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.

      3. DETERMINATION OF SUFFICIENT CLEARING BIDS, WINNING BID RATE AND
APPLICABLE RATE.

      (a) Not earlier than the Submission Deadline on each Auction Date for
shares of a series of Municipal Preferred, the Auction Agent shall assemble all
valid Orders submitted or deemed submitted to it by the Broker-Dealers in
respect of shares of such series (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 for such series:

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

            (ii) from the Submitted Orders for shares of such series whether:

                  (A) the number of Outstanding shares of such series subject
            to Submitted Bids of Potential Holders specifying one or more rates
            equal to or lower than the Maximum Rate for shares of such series;

            exceeds or is equal to the sum of:


<PAGE>

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

                  (C) the number of Outstanding shares of such series subject
            to Submitted Sell Orders

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

            (iii) if Sufficient Clearing Bids for shares of such series exist,
      the lowest rate specified in such Submitted Bids (the "Winning Bid Rate"
      for shares of such series) 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
            such series 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;

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

      (b) Promptly after the Auction Agent has made the determinations pursuant
to subparagraph (a) of this paragraph 3, the Auction Agent shall advise the
Trust of the Maximum Rate for shares of the series of Municipal Preferred for
which an Auction is being held on the Auction Date and, based on such
determination, the Applicable Rate for shares of such series for the next
succeeding Rate Period thereof as follows:

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

            (ii) if Sufficient Clearing Bids for shares of such series do not
      exist (other than because all of the Outstanding shares of such series
      are subject to Submitted Hold Orders), that the Applicable Rate for all
      shares of such series for the next succeeding Rate Period thereof shall
      be equal to the Maximum Rate for shares of such series; or


<PAGE>

            (iii) if all of the Outstanding shares of such series are subject
      to Submitted Hold Orders, that the Applicable Rate for all shares of such
      series for the next succeeding Rate Period thereof shall be as set forth
      in subparagraph (c) of this paragraph 3.

     (c) For purposes of subparagraph (b)(iii) of this paragraph 3, the
Applicable Rate for shares of such series for the next succeeding Rate Period
of shares of such series shall be equal to the lesser of the Kenny Index (if
such Rate Period consists of fewer than 183 Rate Period Days) or the product of
(A) (I) the "AA" Composite Commercial Paper Rate on such Auction Date for such
Rate Period, if such Rate Period consists of fewer than 183 Rate Period Days;
(II) the Treasury Bill Rate on such Auction Date for such Rate Period, if such
Rate Period consists of more than 182 but fewer than 365 Rate Period Days; or
(III) the Treasury Note Rate on such Auction Date for such Rate Period, if such
Rate Period is more than 364 Rate Period Days (the rate described in the
foregoing clause (A)(I), (II) or (III), as applicable, being referred to herein
as the "Benchmark Rate") and (B) 1 minus the maximum marginal regular Federal
individual income tax rate applicable to ordinary income or the maximum
marginal regular Federal corporate income tax rate applicable to ordinary
income, whichever is greater; provided, however, that if the Trust has notified
the Auction Agent of its intent to allocate to shares of such series in such
Rate Period any net capital gains or other income taxable for Federal income
tax purposes ("Taxable Income"), the Applicable Rate for shares of such series
for such Rate Period will be (i) if the Taxable Yield Rate (as defined below)
is greater than the Benchmark Rate, then the Benchmark Rate, or (ii) if the
Taxable Yield Rate is less than or equal to the Benchmark Rate, then the rate
equal to the sum of (x) the lesser of the Kenny Index (if such Rate Period
consists of fewer than 183 Rate Period Days) or the product of the Benchmark
Rate multiplied by the factor set forth in the preceding clause (B) and (y) the
product of the maximum marginal regular Federal individual income tax rate
applicable to ordinary income or the maximum marginal regular Federal corporate
income tax applicable to ordinary income, whichever is greater, multiplied by
the Taxable Yield Rate. For purposes of the foregoing, "Taxable Yield Rate"
means the rate determined by (a) dividing the amount of Taxable Income
available for distribution per such share of Municipal Preferred by the number
of days in the Dividend Period in respect of which such Taxable Income is
contemplated to be distributed, (b) multiplying the amount determined in (a)
above by 365 (in the case of a Dividend Period of 7 Rate Period Days) or 360
(in the case of any other Dividend Period), and (c) dividing the amount
determined in (b) above by $25,000.

     4. ACCEPTANCE AND REJECTION OF SUBMITTED BIDS AND SUBMITTED SELL ORDERS
AND ALLOCATION OF SHARES. Existing Holders shall continue to hold the shares of
Municipal Preferred that are subject to Submitted Hold Orders, and, based on
the determinations made pursuant to subparagraph (a) of paragraph 3 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 a series of Municipal
Preferred have been made, all Submitted Sell Orders with respect to shares of
such series shall be accepted and, subject to the provisions of subparagraphs
(d) and (e) of this paragraph 4, Submitted Bids with respect to shares of such
series shall be accepted or rejected as follows in the following order of
priority and all other Submitted Bids with respect to shares of such series
shall be rejected:

            (i) Existing Holders' Submitted Bids for shares of such series
      specifying any rate that is higher than the Winning Bid Rate for shares

      of such series shall be accepted, thus requiring each such Existing
      Holder to sell the shares of Municipal Preferred subject to such
      Submitted Bids;

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

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

            (iv) each Existing Holders' Submitted Bid for shares of such series
      specifying a rate that is equal to the Winning Bid Rate for shares of
      such series shall be rejected, thus entitling such Existing Holder to
      continue to hold the share of Municipal Preferred subject to such
      Submitted Bid, unless the number of Outstanding shares of Municipal
      Preferred subject to all such Submitted Bids shall be greater than the
      number of shares of Municipal Preferred ("remaining shares") in the
      excess of the Available Municipal Preferred of such series over the
      number of shares of Municipal Preferred 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 Municipal Preferred subject to such Submitted Bid, but only in
      an amount equal to the number of shares of Municipal Preferred of such
      series obtained by multiplying the number of remaining shares by a
      fraction, the numerator of which shall be the number of Outstanding
      shares of Municipal Preferred held by such Existing Holder subject to
      such Submitted Bid and the denominator of which shall be the aggregate
      number of Outstanding shares of Municipal Preferred subject to such
      Submitted Bids made by all such Existing Holders that specified a rate
      equal to the Winning Bid Rate for shares of such series; and

            (v) each Potential Holder's Submitted Bid for shares of such series
      specifying a rate that is equal to the Winning Bid Rate of Shares of such
      series shall be accepted but only in an amount equal to the number of
      shares of such series obtained by multiplying the number of shares in the
      excess of the Available Municipal Preferred of such series over the
      number of shares of Municipal Preferred 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 Municipal Preferred subject to such Submitted Bids and the
      denominator of which shall be the aggregate number of Outstanding shares
      of Municipal Preferred subject to such Submitted Bids made by all such
      Potential Holders that specified a rate equal to the Winning Bid Rate for
      shares of such series.

      (b) If Sufficient Clearing Bids for shares of a series of Municipal
Preferred have not been made (other than because all of the Outstanding shares
of such series are subject to Submitted Hold Orders), subject to the provisions
of subparagraph (d) of this paragraph 4, Submitted Orders for shares of such
series shall be accepted or rejected as follows in the following order of
priority and all other Submitted Bids for shares of such series shall be
rejected:


<PAGE>

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

            (ii) Potential Holders' Submitted Bids for shares of such series
      specifying any rate that is equal to or lower than the Maximum Rate for
      shares of such series shall be accepted; and

            (iii) Each Existing Holder's Submitted Bid for shares of such
      series specifying any rate that is higher than the Maximum Rate for
      shares of such series and the Submitted Sell Orders for shares of such
      series 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 such series
      subject to such Submitted Bid or Submitted Sell Order, but in both cases
      only in an amount equal to the number of shares of such series obtained
      by multiplying the number of shares of such series 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 such
      series 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 such series subject to all such Submitted
      Bids and Submitted Sell Orders.

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

     (d) If, as a result of the procedures described in clause (iv) or (v) of
subparagraph (a) or clause (iii) of subparagraph (b) of this paragraph 4, 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 a series of
Municipal Preferred on 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 Municipal Preferred of such series 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 so purchased or sold by each
Existing Holder or Potential Holder on such Auction Date shall be whole shares
of Municipal Preferred.

     (e) If, as a result of the procedures described in clause (v) of paragraph
(a) of this paragraph 4, any Potential Holder would be entitled or required to
purchase less than a whole share of series of Municipal Preferred on any
Auction Date, the Auction Agent shall, in such manner as it shall determine in
its sole discretion, allocate shares of Municipal Preferred of such series for
purchase among Potential Holders so that only whole shares of Municipal
Preferred of such series 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 Municipal Preferred of such
series on such Auction Date.

     (f) Based on the results of each Auction for shares of a series of
Municipal Preferred, the Auction Agent shall determine the aggregate number of
shares of such series to be purchased and the aggregate number of shares of
such series to be sold by Potential Holders and Existing Holders and, with
respect to each Potential Holder and Existing Holder, to the extent that such

<PAGE>

aggregate number of shares to be purchased and such aggregate number of shares
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 Municipal
Preferred of such series. Notwithstanding any provision of the Auction
Procedures or the Settlement Procedures to the contrary, in the event an
Existing Holder or Beneficial Owner of shares of a series of Municipal
Preferred with respect to whom a Broker-Dealer submitted a Bid to the Auction
Agent for such shares that was accepted in whole or in part, or submitted or is
deemed to have submitted a Sell Order for such shares that was accepted in
whole or in part, fails to instruct its Agent Member to deliver such shares
against payment therefor, partial deliveries of shares of Municipal Preferred
that have been made in respect of Potential Holders' or Potential Beneficial
Owners' Submitted Bids for shares of such series that have been accepted in
whole or in part shall constitute good delivery to such Potential Holders and
Potential Beneficial Owners.

     (g) Neither the Trust nor the Auction Agent nor any affiliate of either
shall have any responsibility or liability with respect to the failure of an
Existing Holder, a Potential Holder, a Beneficial Owner, a Potential Beneficial
Owner or its respective Agent Member to deliver shares of Municipal Preferred
of any series or to pay for shares of Municipal Preferred of any series sold or
purchased pursuant to the Auction Procedures or otherwise.

     5. NOTIFICATION OF ALLOCATIONS. Whenever the Trust intends to include any
net capital gain or other income taxable for Federal income tax purposes in any
dividend on shares of Municipal Preferred, the Trust shall, in the case of a
Minimum Rate Period or a Special Rate Period of 28 Rate Period Days or fewer,
and may, in the case of any other Special Rate Period, notify the Auction Agent
of the amount to be so included not later than the Dividend Payment Date next
preceding the Auction Date on which the Applicable Rate for such dividend is to
be established. Whenever the Auction Agent receives such notice from the Trust,
it will be required in turn to notify each Broker-Dealer, who, on or prior to
such Auction Date, in accordance with its Broker-Dealer Agreement, will be
required to notify its Beneficial Owners and Potential Beneficial Owners of
shares of Municipal Preferred believed by it to be interested in submitting an
Order in the Auction to be held on such Auction Date.

     6. AUCTION AGENT. For so long as any shares of Municipal Preferred are
outstanding, the Auction Agent, duly appointed by the Trust to so act, shall be
in each case a commercial bank, trust company or other financial institution
independent of the Trust and its affiliates (which however, may engage or have
engaged in business transactions with the Trust or its affiliates) and at no
time shall the Trust or any of its affiliates act as the Auction Agent in
connection with the Auction Procedures. If the Auction Agent resigns or for any
reason its appointment is terminated during any period that any shares of
Municipal Preferred are outstanding, the Board of Trustees shall use its best
efforts promptly thereafter to appoint another qualified commercial bank, trust
company or financial institution to act as the Auction Agent. The Auction
Agent's registry of Existing Holders of shares of a series of Municipal
Preferred shall be conclusive and binding on the Broker-Dealers. A
Broker-Dealer may inquire of the Auction Agent between 3:00 p.m. on the
Business Day preceding an Auction for shares of a series of Municipal Preferred
and 9:30 a.m. on the Auction Date for such Auction to ascertain the number of
shares of a series in respect of which the Auction Agent has determined such
Broker-Dealer to be an Existing Holder. If such Broker-Dealer believes it is
the Existing Holder of fewer shares of such series than specified by the
Auction Agent in response to such Broker-Dealer's inquiry, such Broker-Dealer
may so inform the Auction Agent of that belief. Such Broker-Dealer shall not,
in its capacity as Existing Holder of shares of such series, submit Orders in
such Auction in respect of shares of such series covering in the aggregate more

<PAGE>

than the number of shares of such series specified by the Auction Agent in
response to such Broker-Dealer's inquiry.

     7. TRANSFER OF SHARES OF MUNICIPAL PREFERRED. Unless otherwise permitted
by the Trust, a Beneficial Owner or an Existing Holder may sell, transfer or
otherwise dispose of shares of Municipal Preferred only in whole shares and
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, however, that (a) a sale, transfer or other disposition of shares of
Municipal Preferred from a customer of a Broker-Dealer who is listed on the
records of that Broker-Dealer as the holder of such shares to that
Broker-Dealer or another customer of that Broker-Dealer shall not be deemed to
be a sale, transfer or other disposition for purposes of this paragraph 7 if
such Broker-Dealer remains the Existing Holder of the shares so sold,
transferred or disposed of immediately after such sale, transfer or disposition
and (b) in the case of all transfers other than pursuant to Auctions, the
Broker-Dealer (or other Person, if permitted by the Trust) to whom such
transfer is made shall advise the Auction Agent of such transfer.

     8. GLOBAL CERTIFICATE. Prior to the commencement of a Voting Period, (i)
all of the shares of a series of Municipal Preferred outstanding from time to
time shall be represented by one global certificate registered in the name of
the Securities Depository or its nominee and (ii) no registration of transfer
of shares of a series of Municipal Preferred shall be made on the books of the
Trust to any Person other than the Securities Depository or its nominee.
