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

                The Registrant, Colonial Management Associates, Inc. and their
                respective trustees, directors and officers are insured by a
                directors and officers/errors and omissions liability policy.

     2.1  SHAREHOLDER MEETINGS. The annual meeting of the shareholders of the
Trust shall be held between April 1 and May 31 in each year, beginning in 2000,
on a date and at a time within that period set by the Trustees. A special

Trustees, by the president or, if the Trustees and the president shall fail to
call any meeting of shareholders for a period of 30 days after written
application of one or more shareholders who hold at least 10% of all outstanding
shares of the Trust, then such shareholders may call such meeting. Each call of
a meeting shall state the place, date, hour and purposes of the meeting.

     2.2  PLACE OF MEETINGS. All meetings of the shareholders shall be held at
the principal office of the Trust, or, to the extent permitted by the
Declaration of Trust, at such other place within the United States as shall be

the final adjournment of such meeting. The placing of a shareholder's name on a
proxy pursuant to telephonic or electronically transmitted instructions obtained
pursuant to procedures reasonably designed to verify that such instructions have
been authorized by such shareholder shall constitute execution of such proxy by
or on behalf of such shareholder.

shares of a series of Municipal Preferred, shall mean (i) (A) in the case of any
Minimum Rate Period or any Special Rate Period of fewer than 49 Rate Period
Days, the interest equivalent of the 30-day rate; provided, however, that if

equivalent of the 60-day and 90-day rates; (3) 85 or more but fewer than 99 Rate
Period Days, the interest equivalent of the 90-day rate; (4) 99 or more but
fewer than 120 Rate Period Days, the arithmetic average of the interest

of New York for the Business Day next preceding such date; or (ii) in the event
that the Federal Reserve Bank of New York does not make available any such rate,
then the arithmetic average of such rates, as quoted on a discount basis or
otherwise, by the Commercial Paper Dealers to the Auction Agent for the close of
business on the Business Day next preceding such date. If any Commercial Paper
Dealer does not quote a rate required to determine the "AA" Composite Commercial
Paper Rate, the "AA" Composite Commercial Paper Rate shall be determined on the
basis of the quotation or quotations furnished by the remaining Commercial Paper
Dealer or Commercial Paper Dealers and any Substitute Commercial Paper Dealer or
Substitute Commercial Paper Dealers selected by the Trust to provide such rate
or rates not being supplied by any Commercial Paper Dealer or Commercial Paper
Dealers, as the case may be, or, if the Trust does not select any such
Substitute Commercial Paper Dealer or Substitute Commercial Paper Dealers, by
the remaining Commercial Paper Dealer or Commercial Paper Dealers. For purposes
of this definition, the "interest equivalent" of a rate stated on a discount
basis (a "discount rate") for commercial paper of a given days' maturity shall
be equal to the quotient (rounded upwards to the next higher one-thousandth

deemed to be an Affiliate nor shall any corporation or any Person controlled by,
in control of or under common control with such corporation, one of the

generated such receivables are (x) settled through clearing house firms with
respect to which the Trust has received prior written authorization from Moody's
or (y) with counterparties having a Moody's long-term debt rating of at least
Baa3; and (ii) the Moody's Discounted Value of Municipal Obligations sold as of

     considered S&P Eligible Assets to the extent the Market Value of such

     Market Value of S&P Eligible Assets, a portion of such Municipal
     Obligations (selected by the Trust) shall not be considered S&P Eligible
     Assets, so that the Market Value of such Municipal Obligations (excluding
     such portion) does not exceed 50% of the aggregate Market Value of S&P
     Eligible Assets;

     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 Part I of this Section 12.1, 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
          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

          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


                                      -32-

          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 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


                                      -33-
<PAGE>   34


     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 Section 12.1; 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.

     (j)  DIVIDENDS CREDITED AGAINST EARLIEST ACCUMULATED BUT UNPAID DIVIDENDS.
Any dividend payment made on shares of Municipal Preferred shall first be
credited against the


                                      -34-
<PAGE>   35


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
for purposes of, Section 852 of the Code.

     3.   GROSS-UP PAYMENTS.

     Holders of shares of Municipal Preferred shall be entitled to receive,
when, as and if declared by the Board of Trustees, out of funds legally
available therefor in accordance with the Declaration, these By-Laws and
applicable law, dividends in an amount equal to the aggregate Gross-up Payments
as follows:

     (a)  MINIMUM RATE PERIODS AND SPECIAL RATE PERIODS OF 28 RATE PERIOD DAYS
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 and/or California state personal 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 Section 12.1 (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


                                      -35-
<PAGE>   36


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 Part I of this Section 12.1
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 _______ that is a Business Day, then the Trust shall designate such
Subsequent Rate Period as a Special Rate Period consisting of the period
commencing at the end of the immediately preceding Rate Period and ending on the
first _______ that is followed by a _______ that is a Business Day preceding
what would otherwise be such last day, in the case of Series __ 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


                                      -36-
<PAGE>   37


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, 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


                                      -37-
<PAGE>   38


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
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:


                                      -38-
<PAGE>   39


               (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).

          (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 elected 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


                                      -39-
<PAGE>   40


     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 (except that,
     notwithstanding the foregoing, but subject to the provisions of paragraph
     10(c) of Part I of this Section 12.1, 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 $60,000,000) or (b) amend,
     alter or repeal the provisions of the Declaration or the By-Laws, including
     this Section 12.1, whether by merger, consolidation or otherwise, so as to
     materially affect any preference, right or power of such shares of
     Municipal Preferred to 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


                                      -40-
<PAGE>   41


     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.

          (ii) 1940 ACT MATTERS. Unless a higher percentage is provided for in
     the Declaration or these By-Laws, (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 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.

          (iii) SEPARATE VOTE BY SERIES. To the extent permitted by the 1940
     Act, with respect to actions set forth in paragraph 5(c)(i) and paragraph
     5(c)(ii) above (including amendment, alteration or repeal of the provisions
     of the Declaration of Trust or the By-Laws, whether by merger,
     consolidation or otherwise) that would adversely affect the rights of one
     or more series of Municipal Preferred (the "Affected Series") 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 proxy, either in writing or at a
     meeting (each such Affected Series voting as a separate class).

     (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 Section 12.1 viewed by Moody's or
S&P as a predicate for any such definition, and any such


                                      -41-
<PAGE>   42


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
(i) 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 and S&P Volatility Factor) and
(ii) 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:

     (e)  VOTING RIGHTS SET FORTH HEREIN ARE SOLE VOTING RIGHTS. Unless
otherwise required by law, these By-Laws 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 this Section
12.1, by the other provisions of these By-Laws or the Declaration, by statute or
otherwise, no Holder shall be entitled to vote


                                      -42-
<PAGE>   43


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
Part I of this Section 12.1 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.

     (i)  Notwithstanding any provision of these By-Laws to the contrary,
neither the Holders of Municipal Preferred, nor the Holders of any one or more
series thereof, shall be entitled to vote as a separate class with respect to
any matter, if such separate class vote is prohibited by the 1940 Act.

     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 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.


                                      -43-
<PAGE>   44


     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 and Moody's, 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.

<PAGE>   45


     (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
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


                                      -45-
<PAGE>   46


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 Part I of this
Section 12.1, (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
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


                                      -46-
<PAGE>   47


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.


                                      -47-
<PAGE>   48


          (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 a 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.


                                      -48-
<PAGE>   49


     (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 Section
12.1) 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 evidenced by a promissory note or other evidence of indebtedness
and is an amount not exceeding 5% of the value of the total assets of the Trust
at the time of the borrowing; for purposes of the foregoing, "temporary purpose"
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


                                      -49-
<PAGE>   50


     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 subparagraph (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").

          (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


                                      -50-
<PAGE>   51


     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 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, these By-Laws 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


                                      -51-
<PAGE>   52


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 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


                                      -52-
<PAGE>   53


available funds therefor in accordance with the Declaration, these By-Laws 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 occur if at any time after the date specified for
redemption in a Notice of Redemption 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 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 Part I of this Section 12.1. 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


                                      -53-
<PAGE>   54


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 or these By-Laws 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 Part I
of this Section 12.1 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.

     (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


                                      -54-
<PAGE>   55


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 Massachusetts business trust or
corporation nor the merger or consolidation of any Massachusetts business trust
or corporation 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.

     (a)  AMENDMENT OF THIS SECTION 12.1 TO ADD ADDITIONAL SERIES. Subject to
the provisions of subparagraph (c) of paragraph 10 of Part I of this Section
12.1, the Board of Trustees may, by resolution duly adopted, without shareholder
approval (except as otherwise provided by this Section 12.1 or required by
applicable law), amend Section 12.1 to (1) reflect any amendment hereto which
the Board of Trustees is entitled to adopt pursuant to the terms of this Section
12.1 without shareholder approval or (2) add additional series of Municipal
Preferred or additional shares of a series of Municipal Preferred (and terms
relating thereto) to the series and shares of Municipal Preferred theretofore
described thereon. Each such additional series and all such additional shares
shall be governed by the terms of this Section 12.1.

     (b)  [RESERVED]

     (c)  NO FRACTIONAL SHARES. No fractional shares of Municipal Preferred
shall be issued.

     (d)  STATUS OF SHARES OF MUNICIPAL PREFERRED REDEEMED, EXCHANGED OR
OTHERWISE ACQUIRED BY THE TRUST. Shares of Municipal Preferred which are
redeemed, exchanged or otherwise acquired by the Trust shall return to the
status of authorized and unissued Preferred Shares without designation as to
series.

     (e)  BOARD MAY RESOLVE AMBIGUITIES. To the extent permitted by applicable
law, the Board of Trustees may interpret or adjust the provisions of this
Section 12.1 to resolve any inconsistency or ambiguity or to remedy any formal
defect, and may amend this Section 12.1 with respect to any series of Municipal
Preferred prior to this issuance of shares of such series.

     (f)  HEADINGS NOT DETERMINATIVE. The headings contained in this Section
12.1 are for convenience of reference only and shall not affect the meaning or
interpretation of this Section 12.1.

     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 Part II of this Section 12.1

whole shares shall be valid.

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

                                      -58-
<PAGE>   59

          (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

               (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

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

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

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


                                      -59-
<PAGE>   60


     such Existing Holder, and if the number of shares of such series subject to
     such Hold Order 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;

               (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:

               (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


                                      -61-
<PAGE>   62


          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

          (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 greater of the maximum marginal regular
Federal individual income tax rate applicable to ordinary income or the maximum
marginal regular


                                      -62-
<PAGE>   63


Federal corporate income tax rate applicable to ordinary income; 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 Part II of
this Section 12.1, 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;


                                      -63-
<PAGE>   64


          (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:

          (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;


                                      -64-
<PAGE>   65


          (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


                                      -65-
<PAGE>   66


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 Benefit 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


                                      -66-
<PAGE>   67


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 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 Part II of this Section 12.1 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.

                                   ARTICLE 13

                                   AMENDMENTS

     These By-Laws may be amended or replaced, in whole or in part, by a
majority of the Trustees then in office at any meeting of the Trustees, or by
one or more writings signed by such a majority. Any action required to be taken
by a majority of the Trustees under this Article may also be taken by a
committee of the Trustees duly appointed for the purpose.

effective, prior to the execution of this Agreement. If it is contemplated, at
the time this Agreement is executed, that a post-effective amendment to the
registration statement will be filed under the 1933 Act and must be declared
effective before the offering of the Shares may commence, the term "Registration
Statement" as used in this Agreement means the registration statement as amended
by said post-effective amendment. If the Trust has filed an abbreviated
registration statement to register an additional amount of Shares pursuant to

reference herein to the term "Registration Statement" shall include such Rule
462 Registration Statement. The term "Prospectus" as used in this Agreement

have been amended from time to time prior to the date of the Prospectus,
together with any other prospectus and statement of additional information
relating to the Trust other than the Prospectus approved in writing by or
directly or indirectly prepared by the Trust or the Advisor; it being understood
that the definition of Prepricing Prospectus above shall not include any

     2.   AGREEMENTS TO SELL AND PURCHASE. (a) The Trust hereby agrees, subject
to all the terms and conditions set forth herein, to issue and sell to the
Underwriters and, upon the basis of the representations, warranties and
agreements of the Trust and the Advisor herein contained and subject to all the
terms and conditions set forth herein, each Underwriter agrees severally and not
jointly to purchase from the Trust, at a purchase price of $15.00 per share, the
number of Firm Shares set forth opposite the name of such Underwriter in
Schedule I hereto.

     (b)  The Trust also agrees, subject to all the terms and conditions set
forth herein, to sell to the Underwriters, and, upon the basis of the
representations, warranties and agreements of the Trust herein contained and
subject to all the terms and conditions set forth herein, the Underwriters shall
have the right to purchase from the Trust, at the same purchase price per share
as the Underwriters shall pay for the Firm Shares, pursuant to an option (the
"over-allotment option") which may be exercised at any time and from time to
time prior to 9:00 P.M., New York City time, on the 45th day after the date of
the Prospectus (or, if such 45th day shall be a Saturday or Sunday or a holiday,
on the next business day thereafter when the American Stock Exchange is open for
trading), up to an aggregate of 360,000 Option Shares. Option Shares may be
purchased only for the purpose of covering over-allotments made in connection
with the offering of the Firm Shares. Upon any exercise of the over-allotment
option, each Underwriter, severally and not jointly, agrees to purchase from the
Trust the number of Option Shares (subject to such adjustments as you may
determine in order to avoid fractional shares) which bears the same proportion
to the number of Option Shares to be purchased by the Underwriters as the number
of Firm Shares set forth opposite the name of such Underwriter in Schedule I
hereto (or such number of Firm Shares increased as set forth in Section 11
hereof) bears to the aggregate number of Firm Shares.

     (c)  The Trust also agrees, subject to all the terms and conditions set
forth herein, to sell to the Advisor, and, upon the basis of the
representations, warranties and agreements of the Trust herein contained and
subject to all the terms and conditions set forth herein, the Advisor shall have
the right to purchase from the Trust, at the same purchase price per share as
the Underwriters shall pay for the Option Shares, pursuant to an option (the
"Advisor Option") which may be exercised at any time and from time to time prior
to 9:00 P.M., New York City time, on the 45th day after the date of the
Prospectus (or, if such 45th day shall be a Saturday or Sunday or a holiday, on
the next business day thereafter when the American Stock Exchange is open for
trading), up to an aggregate of 1,000 shares of beneficial interest of the Trust
(the "Advisor Shares").

     3.   TERMS OF PUBLIC OFFERING. The Trust and the Advisor have been advised
by you that the Underwriters propose to make a public offering of their
respective Shares as soon after the Registration Statement and this Agreement
have become effective as in your judgment is advisable and initially to offer

     5.   AGREEMENTS OF THE TRUST AND THE ADVISOR. The Trust and the Advisor,
jointly and severally, agree with the several Underwriters as follows:

     (a)  If, at the time this Agreement is executed and delivered, it is
necessary for the Registration Statement or a post-effective amendment thereto
to be declared effective under the 1933 Act before the offering of the Shares
may commence, the Trust will endeavor to cause the Registration Statement or
such post-effective amendment to become effective under the 1933 Act as soon as
possible and will advise you promptly and, if requested by you, will confirm
such advice in writing when the Registration Statement or such post-effective
amendment has become effective.

                                                                               5



     (b)  The Trust will advise you promptly and, if requested by you, will
confirm such advice in writing: (i) of any request made by the Commission for
amendment of or a supplement to the Registration Statement, any Prepricing
Prospectus or the Prospectus (or any amendment or supplement to any of the
foregoing) or for additional information, (ii) of the issuance by the
Commission, the National Association of Securities Dealers, Inc. (the "NASD"),
any state securities commission, any national securities exchange, any
arbitrator, any court or any other governmental, regulatory, self-regulatory or
administrative agency or any official of any order suspending the effectiveness
of the Registration Statement, prohibiting or suspending the use of the
Prospectus or any Prepricing Prospectus, or any sales material (as hereinafter
defined), of any notice pursuant to Section 8(e) of the 1940 Act, of the
suspension of qualification of the Shares for offering or sale in any
jurisdiction, or the initiation of any proceeding for any such purposes, (iii)
of receipt by the Trust, the Advisor, any affiliate of the Trust or the Advisor
or any representative or attorney of the Trust or the Advisor of any other
material communication from the Commission, the NASD, any state securities
commission, any national securities exchange, any arbitrator, any court or any
other governmental, regulatory, self-regulatory or administrative agency or any
official relating to the Trust (if such communication relating to the Trust is
received by such person within three years after the date of this Agreement),
the Registration Statement, the 1940 Act Notification, the Prospectus, any
Prepricing Prospectus, any sales material (as herein defined) (or any amendment
or supplement to any of the foregoing) or this Agreement or any of the Trust
Agreements and (iv) within the period of time referred to in paragraph (f)
below, of any material adverse change in the condition (financial or other),
business, prospects, properties, net assets or results of operations of the
Trust or the Advisor or of the happening of any other event which makes any
statement of a material fact made in the Registration Statement or the
Prospectus, or any Prepricing Prospectus or any sales materials (as herein
defined) (or any amendment or supplement to any of the foregoing) untrue or
which requires the making of any additions to or changes in the Registration
Statement or the Prospectus, or any Prepricing Prospectus or any sales materials
(as herein defined) (or any amendment or supplement to any of the foregoing) in
order to state a material fact required by the 1933 Act, the 1940 Act or the
Rules and Regulations to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, or of the necessity to amend or supplement the Registration
Statement, the Prospectus, or any Prepricing Prospectus or any sales material
(as herein defined) (or any amendment or supplement to any of the foregoing) to
comply with the 1933 Act, the 1940 Act, the Rules and Regulations or any other
law or order of any court or regulatory body. If at any time the Commission, the
NASD, any state securities commission, any national securities exchange, any
arbitrator, any court or any other governmental, regulatory, self-regulatory or
administrative agency or any official shall issue any order suspending the
effectiveness of the Registration Statement, prohibiting or suspending the use
of the Prospectus or any sales material (as herein defined) (or any amendment or
supplement to any of the foregoing) or suspending the qualification of the
Shares for offering or sale in any jurisdiction, the Trust will make every
reasonable effort to obtain the withdrawal of such order at the earliest
possible time.

     (c)  The Trust will furnish to you, without charge, three signed copies of
the Registration Statement as originally filed with the Commission and of each
amendment thereto,


<PAGE>   6

                                                                               6



including financial statements and all exhibits thereto, and will also furnish
to you, without charge, such number of conformed copies of the Registration
Statement as originally filed and of each amendment thereto, but without
exhibits, as you may request.

     (d)  The Trust will not (i) file any amendment to the Registration
Statement or make any amendment or supplement to the Prospectus, or any sales
material (as herein defined), of which you shall not previously have been
advised or to which you shall reasonably object after being so advised or (ii)
so long as, in the opinion of counsel for the Underwriters, a Prospectus is
required by the 1933 Act to be delivered in connection with sales by any
Underwriter or any dealer, file any information, documents or reports pursuant
to the Securities Exchange Act of 1934, as amended (the "1934 Act"), without
delivering a copy of such information, documents or reports to you, as
Representatives of the several Underwriters, prior to or concurrently with such
filing.

     (e)  Prior to the execution and delivery of this Agreement, the Trust has
delivered to you, without charge, in such quantities as you have requested,
copies of each form of the Prepricing Prospectus. The Trust consents to the use,
in accordance with the provisions of the 1933 Act and with the state securities
or blue sky laws of the jurisdictions in which the Shares are offered by the
several Underwriters and by dealers, prior to the date of the Prospectus, of
each Prepricing Prospectus so furnished by the Trust.

     (f)  As soon after the execution and delivery of this Agreement as possible
and thereafter from time to time for such period as in the opinion of counsel
for the Underwriters a prospectus is required by the 1933 Act to be delivered in
connection with sales by any Underwriter or any dealer, the Trust will
expeditiously deliver to each Underwriter and each dealer, without charge, as
many copies of the Prospectus (and of any amendment or supplement thereto) as
you may reasonably request. The Trust consents to the use of the Prospectus (and
of any amendment or supplement thereto) in accordance with the provisions of the
1933 Act and with the state securities or blue sky laws of the jurisdictions in
which the Shares are offered by the several Underwriters and by all dealers to
whom Shares may be sold, both in connection with the offering and sale of the
Shares and for such period of time thereafter as the Prospectus is required by
the 1933 Act to be delivered in connection with sales by any Underwriter or any
dealer. If during such period of time any event shall occur that in the judgment
of the Trust or in the opinion of counsel for the Underwriters is required to be
set forth in the Registration Statement or the Prospectus (as then amended or
supplemented) or should be set forth therein in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, or if it is necessary to supplement or amend the Registration
Statement or the Prospectus to comply with the 1933 Act, the 1940 Act, the Rules
and Regulations or any other federal law, rule or regulation, or any state
securities or blue sky disclosure laws, rules or regulations, the Trust will
forthwith prepare and, subject to the provisions of paragraph (d) above,
promptly file with the Commission an appropriate supplement or amendment
thereto, and will expeditiously furnish to the Underwriters and dealers, without
charge, a reasonable number of copies thereof; provided that, if the supplement
or amendment is required exclusively as a result of a misstatement in or
omission from the information provided to the Trust in writing by the
Underwriters expressly for use in the Prospectus, the Trust may deliver such
supplement or

                                                                               7



amendment to the Underwriters and dealers at a reasonable charge not to exceed
the actual cost thereof to the Trust. In the event that the Trust and you, as
Representatives of the several Underwriters, agree that the Registration
Statement or the Prospectus should be amended or supplemented, the Trust, if
requested by you, will promptly issue a press release announcing or disclosing
the matters to be covered by the proposed amendment or supplement.

     (g)  The Trust will cooperate with you and with counsel for the
Underwriters in connection with the registration or qualification of the Shares
for offering and sale by the several Underwriters and by dealers under the
securities or blue sky laws of such jurisdictions as you may designate and will
file such consents to service of process or other documents necessary or
appropriate in order to effect such registration or qualification; provided that
in no event shall the Trust be obligated to qualify to do business or as a
dealer in securities in any jurisdiction where it is not now so qualified or to
take any action which would subject it to service of process in suits, other
than those arising out of the offering or sale of the Shares, in any
jurisdiction where it is not now so subject nor will the Trust be obligated to
execute a general consent to service of process.

     (h)  The Trust will make generally available to its security holders an
earnings statement, which need not be audited, covering a twelve-month period
ending not later than 15 months after the effective date of the Registration
Statement as soon as practicable after the end of such period, which earnings
statement shall satisfy the provisions of Section 11(a) of the 1933 Act and Rule
158 of the 1933 Act Rules and Regulations.

     (i)  During the period of five years hereafter, the Trust will furnish to
you (i) as soon as available, a copy of each report of the Trust mailed to
shareholders or filed with the Commission or furnished to the American Stock
Exchange (the "AMEX") other than reports on Form N-SAR, and (ii) from time to
time such other information concerning the Trust as you may reasonably request.

     (j)  If this Agreement shall terminate or shall be terminated after
execution pursuant to any provisions hereof (otherwise than by notice given by
you terminating this Agreement pursuant to Section 12 hereof or pursuant to the
second paragraph of Section 11 hereof) or if this Agreement shall be terminated
by the Underwriters because of any failure or refusal on the part of the Trust
or the Advisor to comply with the terms or fulfill any of the conditions of this
Agreement, the Trust and the Advisor, jointly and severally, agree to reimburse
the Representatives for all out-of-pocket expenses (including reasonable fees
and expenses of counsel for the Underwriters) incurred by the Underwriters in
connection herewith.

     (k)  The Trust will apply the net proceeds from the sale of the irm Shares,
and of the Option Shares, if any, substantially in accordance with the
description set forth in the Prospectus and in such a manner as to comply with
the investment objectives, policies and restrictions of the Trust as described
in the Prospectus.

     (l)  The Trust will timely file the requisite copies of the Prospectus with
the Commission pursuant to Rule 497(c) or Rule 497(h) of the 1933 Act Rules and
Regulations, whichever is applicable or, if applicable, will timely file the
certification permitted by Rule

497(j) of the 1933 Act Rules and Regulations and will advise you of the time and
manner of such filing.

     (m)  Except as provided in this Agreement, the Trust will not sell,
contract to sell or otherwise dispose of any Common Shares or any securities
convertible into or exercisable or exchangeable for Common Shares, or grant any
options or warrants to purchase Common Shares, for a period of 180 days after
the date of the Prospectus, without the prior written consent of Salomon Smith
Barney Inc.; provided, however, that the Trust may issue and make open market
purchases of Common Shares pursuant to any dividend reinvestment plan of the
Trust in effect as of the Closing Date.

     (n)  Except as stated in this Agreement and in the Prepricing Prospectus
and Prospectus, and except for share repurchases, tender offers or purchases of
Shares in the open market pursuant to the Trust's dividend reinvestment plan,
neither the Trust nor the Advisor has taken, nor will it take, directly or
indirectly, any action designed to or that might reasonably be expected to cause
or result in stabilization or manipulation of the price of the Shares or any
other securities issued by the Trust to facilitate the sale or resale of the
Shares.

     (o)  The Trust will use its best efforts to cause the Shares to be duly
authorized for listing by the AMEX prior to the date the Shares are issued.

     (p)  The Trust will use its best efforts to comply with all requirements
under the Internal Revenue Code of 1986, as amended (the "Code") to qualify as a
regulated investment company under Subchapter M of the Code.

     (q)  The Trust and the Advisor will each use its best efforts to perform
all of the agreements required of it and discharge all conditions to closing as
set forth in this Agreement.

1940 Act and the Rules and Regulations. The Commission has not issued any order

effective and also in such form as it may be when any post-effective amendment
thereto shall become effective and the Prospectus and any supplement or

Rules and Regulations and the 1940 Act Notification when originally filed with
the Commission and any amendment or supplement thereto when filed with the

Shares have been duly authorized and, when issued and delivered to the
Underwriters against payment therefor in accordance with the terms hereof, will

Registration Statement and the Prospectus (and any amendment or supplement to
either of them).

     (d)  Except for the Option Shares and the Advisor Shares and as otherwise

rights calling for the issuance of, or any commitment, plan or arrangement to
issue, any shares of beneficial interest of the Trust or any security

interest of the Trust.

     (e)  The Trust is a business trust duly organized and validly existing in

condition (financial or other), business, prospects, properties, net assets or
results of operations of the Trust; and the Trust has no subsidiaries.

     (f)  There are no legal or governmental proceedings pending or, to the

operations of the Trust.

     (h)  Neither the issuance and sale of the Shares, the execution, delivery
or performance of this Agreement or any of the Trust Agreements by the Trust,
nor the consummation by the Trust of the transactions contemplated hereby or
thereby (A) requires any consent, approval, authorization or other order of, or
registration or filing with, the Commission, the NASD, any state securities

the books and records of the Trust.

     (k)  The execution and delivery of, and the performance by the Trust of its
obligations under, this Agreement and the Trust Agreements have been duly and
validly authorized by the Trust, and this Agreement and the Trust Agreements
have been duly executed and delivered by the Trust and assuming due
authorization, execution and delivery by the other parties thereto, constitute
the valid and legally binding agreements of the Trust, enforceable against the
Trust in accordance with their terms (subject to the qualification that the
enforceability of the Trust's obligations thereunder may be limited by
bankruptcy, insolvency, reorganization, moratorium, and similar laws of general
applicability relating to or affecting creditors' rights, and to general
principles of equity regardless of whether enforceability is considered in a
proceeding in equity or at law), except as rights to indemnity and contribution
hereunder and thereunder may be limited by federal or state securities laws.

     (l)  Except as disclosed in the Registration Statement and the Prospectus
(or any amendment or supplement to either of them), subsequent to the respective
dates as of which such information is given in the Registration Statement and
the Prospectus (or any amendment or supplement to either of them), the Trust has
not incurred any liability or obligation, direct or contingent, or entered into
any transaction, not in the ordinary course of business, that is material to the
Trust, and there has not been any change in the capitalization, or material
increase in the short-term debt or long-term debt, of the Trust, or any material
adverse change, or any development involving or which may reasonably be expected
to involve, a prospective material adverse change, in the condition (financial
or other), business, prospects, properties, net assets or results of operations
of the Trust, whether or not arising in the ordinary course of business (a
"Material Adverse Effect").

     (m)  The Trust has not distributed and, prior to the later to occur of (i)
the Closing Date and (ii) completion of the distribution of the Shares, will not
distribute any offering material in connection with the offering and sale of the
Shares other than the Registration Statement, the Prepricing Prospectus, the
Prospectus or other materials, if any, permitted by the 1933 Act, the 1940 Act
or the Rules and Regulations.

     (n)  (i) The Trust has such permits, licenses, franchises and
authorizations of governmental or regulatory authorities ("permits") as are
necessary to own its properties and to conduct its business in the manner

for any such permits the absence of which would not have a Material Adverse
Effect and subject to such qualifications as may be set forth in the Prospectus;
(ii) the Trust has fulfilled and performed all its material obligations with
respect to such permits and no event has occurred which allows, or after notice
or lapse of time would allow, revocation or termination thereof or results in
any other material impairment of the rights of the Trust under any such permit,
subject in each case to such qualification as may be set forth in the Prospectus
(and any amendment or supplement thereto); and (iii) except as described in the
Prospectus (and


<PAGE>   12


                                                                              12



any amendment or supplement thereto), none of such permits contains any
restriction that is materially burdensome to the Trust, except where the failure
of (i), (ii) or (iii) to be accurate would not, individually or in the
aggregate, have a Material Adverse Effect on the Trust.

     (o)  The Trust maintains a system of internal accounting controls
sufficient to provide reasonable assurances that (i) transactions are executed
in accordance with management's general or specific authorization and with the
applicable requirements of the 1940 Act, the 1940 Act Rules and Regulations and
the Code; (ii) transactions are recorded as necessary to permit preparation of
financial statements in conformity with generally accepted accounting principles
and to maintain accountability for assets and to maintain compliance with the
books and records requirements under the 1940 Act and the 1940 Act Rules and
Regulations; (iii) access to assets is permitted only in accordance with
management's general or specific authorization; and (iv) the recorded
accountability for assets is compared with existing assets at reasonable
intervals and appropriate action is taken with respect to any differences.

     (p)  To the Trust's knowledge, neither the Trust nor any employee or agent
of the Trust has made any payment of funds of the Trust or received or retained
any funds, which payment, receipt or retention of funds is of a character
required to be disclosed in the Prospectus, except for the issuance of up to
6,667 shares of beneficial interest of the Trust to the Advisor to comply with
the net worth requirements of Section 14(a) of the 1940 Act.

     (q)  The Trust has filed all tax returns required to be filed, if any,
which returns are complete and correct in all material respects, and the Trust
is not in default in the payment of any taxes which were payable pursuant to
said returns or any assessments with respect thereto.

     (r)  No holder of any security of the Trust has any right to require
registration of any security of the Trust because of the filing of the
registration statement or consummation of the transactions contemplated by this
Agreement.

     (s)  The Trust, subject to the registration statement having been declared
effective and the filing of the Prospectus under Rule 497 under the 1933 Act
Rules and Regulations, has taken all required action under the 1933 Act, the
1940 Act and the Rules and Regulations to make the public offering and
consummate the sale of the Shares as contemplated by this Agreement.

     (t)  The conduct by the Trust of its business (as described in the
Prospectus) does not require it to be the owner, possessor or licensee of any
patents, patent licenses, trademarks, service marks or trade names which it does
not own, possess or license.

     (u)  The Trust is registered under the 1940 Act as a closed-end,
non-diversified management investment company and the 1940 Act Notification has
been duly filed with the Commission and, at the time of filing thereof and any
amendment or supplement thereto, conformed in all material respects with all
applicable provisions of the 1940 Act and the 1940 Act Rules and Regulations.
The Trust has not received any notice from the Commission pursuant to Section
8(e) of the 1940 Act with respect to the 1940 Act Notification. The Trust is,

                                                                              13



and at all times through the completion of the transactions contemplated hereby,
will be, in compliance in all material respects with the terms and conditions of
the 1933 Act and the 1940 Act. No person is serving or acting as an officer,
director or investment adviser of the Trust except in accordance with the
provisions of the 1940 Act and the 1940 Act Rules and Regulations and the
Investment Advisers Act of 1940, as amended (the "Advisers Act"), and the rules
and regulations of the Commission promulgated under the Advisers Act (the
"Advisers Act Rules and Regulations").

     (v)  Except as stated in this Agreement and in the Prospectus (and any
amendment or supplement thereto), the Trust has not taken, nor will it take,
directly or indirectly, any action designed to or which might reasonably be
expected to cause or result in stabilization or manipulation of the price of any
securities issued by the Trust to facilitate the sale or resale of the Shares,
and the Trust is not aware of any such action taken or to be taken by any
affiliates of the Trust.

     (w)  All advertising and other sales literature (including "prospectus
wrappers") authorized in writing by or prepared by the Trust or the Advisor for
use in connection with the offering and sale of the Shares (collectively, "sales
material") complied and comply in all material respects with the applicable
requirements of the 1933 Act, the 1940 Act, the Rules and Regulations and the
rules and interpretations of the NASD and no such sales material contained or
contains an untrue statement of a material fact or omitted or omits to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

     The "broker kits" prepared by or approved by the Trust or the Advisor for
distribution to and use internally by brokers and dealers participating in the
offering of the Shares accurately and fairly presents the information contained
therein in all material respects for purposes of such internal use and contains
only information the substance of which is included in the Prospectus or the
Statement of Additional Information of the Trust. Any road show slides and road
show scripts prepared or approved in writing by the Trust or the Advisor for use
in presentations to brokers and dealers participating in the offering of the
Shares accurately and fairly present the information contained therein in all
material respects for purposes of such use.

     (x)  Each of the Trust Agreements and the Trust's obligations under this
Agreement and each of the Trust Agreements comply in all material respects with
all applicable provisions of the 1933 Act, the 1940 Act, the Rules and
Regulations, the Advisers Act and the Advisers Act Rules and Regulations.

     (y)  Except as disclosed in the Registration Statement and the Prospectus
(or any amendment or supplement to either of them), no director of the Trust is
an "interested person" (as defined in the 1940 Act) of the Trust or an
"affiliated person" (as defined in the 1940 Act) of any Underwriter.

     (z)  The Shares have been duly authorized for listing, subject to official
notice of issuance, on the AMEX.

                                                                              14



     (aa) The Advisor has considered, and is taking actions to address, the
possible adverse effects of the Year 2000 on the critical computer systems used
by the Advisor and its affiliates on behalf of the Trust. Testing and
remediation of those systems is complete and the Advisor has determined that
recognition and execution of date-sensitive functions involving certain dates
prior to and after December 31, 1999 (the "Year 2000 Problem") will not pose
significant problems for the computer systems used by the Advisor on behalf of
the Trust. The Advisor believes, after reasonable inquiry, that suppliers,
vendors, or financial service organizations used in the operation of the Trust
have remedied or will remedy the Year 2000 Problem and that those suppliers,
vendors or financial service organizations believe that their modifications will
be completed on a timely basis, except to the extent that a failure to remedy by
any such supplier, vendor, or financial service organization would not have a
material adverse effect on the operations of the Trust. The Trust is in
compliance with the Commission's Release No. 33-7558 related to Year 2000
compliance, as amended to date.

     7.   REPRESENTATIONS AND WARRANTIES OF THE ADVISOR. CMA represents and
warrants to each Underwriter that:

     (a)  The Advisor is a corporation duly incorporated and validly existing in
good standing under the laws of the Commonwealth of Massachusetts, with full
corporate power and authority to own, lease and operate its properties and to
conduct its business as described in the Registration Statement and the
Prospectus (and any amendment or supplement to either of them), and is duly
registered and qualified to conduct its business and is in good standing in each
jurisdiction or place where the nature of its properties or the conduct of its
business requires such registration or qualification, except where the failure
so to register or to qualify does not have a material adverse effect on the
condition (financial or other), business, prospects, properties, net assets or
results of operations of the Advisor or on the ability of the Advisor to perform
its obligations under this Agreement and the Management Agreement.

     (b)  The Advisor is duly registered with the Commission as an investment
adviser under the Advisers Act and is not prohibited by the Advisers Act, the
Advisers Act Rules and Regulations, the 1940 Act or the 1940 Act Rules and
Regulations from acting under the Management Agreement for the Trust as
contemplated by the Prospectus (or any amendment or supplement thereto). There
does not exist any proceeding or any facts or circumstances the existence of
which could lead to any proceeding which might adversely affect the registration
of the Advisor with the Commission.

     (c)  There are no legal or governmental proceedings pending or, to the
knowledge of the Advisor, threatened against the Advisor, or to which the
Advisor or any of its properties is subject, that are required to be described
in the Registration Statement or the Prospectus (or any amendment or supplement
to either of them) but are not described as required or that may reasonably be
expected to involve a prospective material adverse change, in the condition
(financial or other), business, prospects, properties, net assets or results of
operations of the Advisor or on the ability of the Advisor to perform its
obligations under this Agreement and the Management Agreement.


<PAGE>   15


                                                                              15



     (d)  Neither the execution, delivery or performance of this Agreement or
the performance of the Management Agreement by the Advisor, nor the consummation
by the Advisor of the transactions contemplated hereby or thereby (A) requires
the Advisor to obtain any consent, approval, authorization or other order of or
registration or filing with, the Commission, the NASD, any state securities
commission, any national securities exchange, any arbitrator, any court,
regulatory body, administrative agency or other governmental body, agency or
official or conflicts or will conflict with or constitutes or will constitute a
breach of or a default under, the certificate of incorporation or by-laws, or
other organizational documents, of the Advisor or (B) conflicts or will conflict
with or constitutes or will constitute a breach of or a default under, any
agreement, indenture, lease or other instrument to which the Advisor is a party
or by which it or any of its properties may be bound, or violates or will
violate any statute, law, regulation or filing or judgment, injunction, order or
decree applicable to the Advisor or any of its properties or will result in the
creation or imposition of any lien, charge or encumbrance upon any property or
assets of the Advisor pursuant to the terms of any agreement or instrument to
which it is a party or by which it may be bound or to which any of the property
or assets of the Advisor is subject. The Advisor is not subject to any order of
any court or of any arbitrator, governmental authority or administrative agency.

     (e)  The execution and delivery of, and the performance by the Advisor of
its obligations under, this Agreement and the Management Agreement have been
duly and validly authorized by the Advisor, and this Agreement and the
Management Agreement have been duly executed and delivered by the Advisor and,
assuming due authorization, execution and delivery by the other parties thereto,
each constitutes the valid and legally binding agreement of the Advisor,
enforceable against the Advisor in accordance with its terms (subject to the
qualification that the enforceability of the Advisor's obligations thereunder
may be limited by bankruptcy, insolvency, reorganization, moratorium and similar
laws of general applicability relating to or affecting creditors' rights, and to
general principles of equity regardless of whether enforceability is considered
in a proceeding in equity or at law), except as rights to indemnity and
contribution hereunder may be limited by federal or state securities laws.

     (f)  The description of the Advisor in the Registration Statement and the
Prospectus (and any amendment or supplement thereto) complied and comply in all
material respects with the provisions of the 1933 Act, the 1940 Act, the
Advisers Act, the Rules and Regulations and the Advisers Act Rules and
Regulations and did not and will not contain an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading.

     (g)  Except as disclosed in the Registration Statement and the Prospectus
(or any amendment or supplement to either of them), subsequent to the respective
dates as of which such information is given in the Registration Statement and
the Prospectus (or any amendment or supplement to either of them), the Advisor
has not incurred any liability or obligation, direct or contingent, or entered
into any transaction, not in the ordinary course of business, that is material
to the Advisor or the Trust and that is required to be disclosed in the
Registration Statement or the Prospectus and there has not been any material
adverse change, or any development


<PAGE>   16

                                                                              16



involving or which may reasonably be expected to involve, a prospective material
adverse change, in the condition (financial or other), business, prospects,
properties, net assets or results of operations of the Advisor, whether or not
arising in the ordinary course of business, or which, in each case, could have a
material adverse effect on the ability of the Advisor to perform its obligations
under this Agreement and the Management Agreement.

     (h)  (i) The Advisor has such permits, licenses, franchises and
authorizations of governmental or regulatory authorities ("permits") as are
necessary to own its properties and to conduct its business in the manner
described in the Prospectus (and any amendment thereto); (ii) the Advisor has
fulfilled and performed all its material obligations with respect to such
permits and no event has occurred which allows, or after notice or lapse of time
would allow, revocation or termination thereof or results in any other material
impairment of the rights of the Advisor under any such permit; and (iii) except
as described in the Prospectus (and any amendment or supplement thereto), none
of such permits contains any restriction that is materially burdensome to the
Advisor, except where the failure of (i), (ii), or (iii) to be accurate would
not, individually or in the aggregate, have a Material Adverse Effect on the
Advisor.

     (i)  Except as stated in this Agreement and in the Prospectus (and in any
amendment or supplement thereto), the Advisor has not taken, nor will it take,
directly or indirectly, any action designed to or which might reasonably be
expected to cause or result in stabilization or manipulation of the price of any
securities issued by the Trust to facilitate the sale or resale of the Shares,
and the Advisor is not aware of any such action taken or to be taken by any
affiliates of the Advisor.

     8.   INDEMNIFICATION AND CONTRIBUTION. (a) The Trust and the Advisor,
jointly and severally, agree to indemnify and hold harmless you and each other
Underwriter and each person, if any, who controls any Underwriter within the
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act from and
against any and all losses, claims, damages, liabilities and expenses (including
reasonable costs of investigation), joint or several, arising out of or based
upon any untrue statement or alleged untrue statement of a material fact
contained in any Prepricing Prospectus or in the Registration Statement or the
Prospectus or in any amendment or supplement thereto, or arising out of or based
upon any omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances under which such statements were made, not misleading, except
insofar as such losses, claims, damages, liabilities or expenses arise out of or
are based upon any untrue statement or omission or alleged untrue statement or
omission which has been made therein or omitted therefrom in reliance upon and
in conformity with the information relating to any Underwriter furnished in
writing to the Trust by or on behalf of any Underwriter expressly for use in
connection therewith; provided, however, that the indemnification contained in
this paragraph (a) with respect to any Prepricing Prospectus, Prospectus or
Registration Statement (or any amendment or supplement to any of the foregoing)
shall not inure to the benefit of any Underwriter (or to the benefit of any
person controlling such Underwriter) on account of any such loss, claim, damage,
liability or expense arising from the sale of the Shares by such Underwriter to
any person if a copy of the Prospectus (or any amendment or supplement thereto)
shall not have been delivered or sent to such person within the time required by
the 1933 Act and


<PAGE>   17


                                                                              17



the 1933 Act Rules and Regulations, and the untrue statement or alleged untrue
statement or omission or alleged omission of a material fact contained in such
Prepricing Prospectus was corrected in the Prospectus (or any amendment or
supplement thereto), provided that the Trust has delivered the Prospectus (or
any amendment or supplement thereto) to the several Underwriters in requisite
quantity on a timely basis to permit such delivery or sending. The foregoing
indemnity agreement shall be in addition to any liability which the Trust or the
Advisor may otherwise have.

     (b)  Any party that proposes to assert the right to be indemnified under
this Section 8 will, promptly after receipt of notice of commencement of any
action against such party in respect of which a claim is to be made against an
indemnifying party or parties under this Section 8, notify each such
indemnifying party of the commencement of such action, enclosing a copy of all
papers served, but the omission to so notify such indemnifying party (i) will
not relieve it from any liability that it may have to any indemnified party
under the foregoing provision of this Section 8 unless, and only to the extent
that, such omission results in the forfeiture of substantive rights or defenses
by the indemnifying party and (ii) will not, in any event, relieve such
indemnifying party from any other obligation (other than pursuant to the
foregoing provision of this Section 8) it may have under this Agreement. If any
action, suit or proceeding shall be brought against any Underwriter or any
person controlling any Underwriter in respect of which indemnity may be sought
against the Trust or the Advisor, such Underwriter or such controlling person
shall promptly notify the Trust or the Advisor, and the Trust or the Advisor
shall assume the defense thereof, including the employment of counsel and
payment of all fees and expenses. Such Underwriter or any such controlling
person shall have the right to employ separate counsel in any such action, suit
or proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Underwriter or such
controlling person unless (i) the Trust or the Advisor have agreed in writing to
pay such fees and expenses, (ii) the Trust and the Advisor have failed to assume
the defense and employ counsel, or (iii) the named parties to any such action,
suit or proceeding (including any impleaded parties) include both such
Underwriter or such controlling person and the Trust or the Advisor and such
Underwriter or such controlling person shall have been advised by its counsel
that representation of such indemnified party and the Trust or the Advisor by
the same counsel would be inappropriate under applicable standards of
professional conduct (whether or not such representation by the same counsel has
been proposed) due to actual or potential differing interests between them (in
which case the Trust and the Advisor shall not have the right to assume the
defense of such action, suit or proceeding on behalf of such Underwriter or such
controlling person). It is understood, however, that the Trust and the Advisor
shall, in connection with any one such action, suit or proceeding or separate
but substantially similar or related actions, suits or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of only one separate firm of
attorneys (in addition to any local counsel) at any time for all such
Underwriters and controlling persons not having actual or potential differing
interests with you or among themselves, which firm shall be designated in
writing by the Representatives, and that all such fees and expenses shall be
reimbursed as they are incurred. The Trust and the Advisor shall not be liable
for any settlement of any such action, suit or proceeding effected without their
written consent (which consent shall not be unreasonably withheld), but if
settled with such written


<PAGE>   18


                                                                              18


consent, or if there be a final judgment for the plaintiff in any such action,
suit or proceeding, the Trust and the Advisor agree to indemnify and hold
harmless any Underwriter, to the extent provided in the preceding paragraph, and
any such controlling person from and against any loss, claim, damage, liability
or expense by reason of such settlement or judgment.

     (c)  Each Underwriter agrees, severally and not jointly, to indemnify and
hold harmless the Trust and the Advisor, their trustees, directors, any officers
who sign the Registration Statement, and any person who controls the Trust or
the Advisor within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act, to the same extent as the foregoing indemnity from the Trust and
the Advisor to each Underwriter, but only with respect to information relating
to such Underwriter furnished in writing by or on behalf of such Underwriter
expressly for use in the Registration Statement, the Prospectus or any
Prepricing Prospectus, or any amendment or supplement thereto. If any action,
suit or proceeding shall be brought against the Trust or the Advisor, any of
their trustees or directors, any such officer, or any such controlling person
based on the Registration Statement, the Prospectus or any Prepricing
Prospectus, or any amendment or supplement thereto, and in respect of which
indemnity may be sought against any Underwriter pursuant to this paragraph (c),
such Underwriter shall have the rights and duties given to the Trust and the
Advisor by paragraph (b) above (except that if the Trust or the Advisor shall
have assumed the defense thereof such Underwriter shall not be required to do
so, but may employ separate counsel therein and participate in the defense
thereof, but the fees and expenses of such counsel shall be at such
Underwriter's expense), and the Trust and the Advisor, their trustees and
directors, any such officer, and any such controlling person shall have the
rights and duties given to the Underwriters by paragraph (b) above. The
foregoing indemnity agreement shall be in addition to any liability which the
Underwriters may otherwise have.

     (d)  If the indemnification provided for in this Section 8 is unavailable
to an indemnified party under paragraphs (a) or (c) hereof in respect of any
losses, claims, damages, liabilities or expenses referred to therein, then an
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or expenses (i) in such proportion
as is appropriate to reflect the relative benefits received by the Trust and the
Advisor on the one hand (treated jointly for this purpose as one person) and the
Underwriters on the other hand from the offering of the Shares, or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Trust and the
Advisor on the one hand (treated jointly for this purpose as one person) and the
Underwriters on the other in connection with the statements or omissions that
resulted in such losses, claims, damages, liabilities or expenses, as well as
any other relevant equitable considerations. The relative benefits received by
the Trust and the Advisor on the one hand (treated jointly for this purpose as
one person) and the Underwriters on the other hand shall be deemed to be in the
same proportion as the total net proceeds from the offering (before deducting
expenses) received by the Trust bear to the total underwriting discounts and
commissions received by the Underwriters, in each case as set forth in the table
on the cover page of the Prospectus. The relative fault of the Trust and the
Advisor on the one hand (treated jointly for this purpose as one person) and the
Underwriters


<PAGE>   19


                                                                              19



on the other hand shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Trust and the Advisor on the one hand (treated jointly for this
purpose as one person) or by the Underwriters on the other hand and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. Any party entitled to contribution will,
promptly after receipt of notice of commencement of any action against such
party in respect of which a claim for contribution may be made under this
Section 8(d), notify such party or parties from whom contribution may be sought,
but the omission so to notify (i) will not relieve the party or parties from
whom contribution may be sought from any other obligation it or they may have
under this Section 8(d), unless such omission results in the forfeiture of
substantive rights or defenses by the party or parties from whom contribution is
being sought and (ii) will not, in any event, relieve the party or parties from
whom contribution may be sought from any other obligation (other than pursuant
to this Section 8(d)) it or they may have under this Agreement. Except for a
settlement entered into pursuant to the last sentence of Section 8(b) hereof, no
party will be liable for contribution with respect to any action or claim
settled without its written consent (which consent shall not be unreasonably
withheld).

     (e)  The Trust, the Advisor and the Underwriters agree that it would not be
just and equitable if contribution pursuant to this Section 8 were determined by
a pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation that does not take account of
the equitable considerations referred to in paragraph (d) above. The amount paid
or payable by an indemnified party as a result of the losses, claims, damages,
liabilities and expenses referred to in paragraph (d) above shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
any claim or defending any such action, suit or proceeding. Notwithstanding the
provisions of this Section 8, no Underwriter shall be required to contribute any
amount in excess of the amount by which such total price of the Shares
underwritten by it and distributed to the public exceeds the amount of any
damages which such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The Underwriters' obligations
to contribute pursuant to this Section 8 are several in proportion to the
respective numbers of Firm Shares set forth opposite their names in Schedule I
hereto (or such numbers of Firm Shares increased as set forth in Section 11
hereof) and not joint.

     (f)  No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened action,
suit or proceeding in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party, unless such settlement includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter of
such action, suit or proceeding.

                                                                              20



     (g)  Notwithstanding any other provisions in this Section 8, no party shall
be entitled to the benefit of any provision under this Agreement which protects
or purports to protect such person against any liability to the Trust or its
security holders to which such person would otherwise be subject by reason of
such person's willful misfeasance, bad faith, or gross negligence, in the
performance of such person's duties hereunder, or by reason of such person's
reckless disregard of such person's obligations and duties hereunder.

     (h)  Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 8 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 8 and the
representations and warranties of the Trust and the Advisor set forth in this
Agreement shall remain operative and in full force and effect, regardless of (i)
any investigation made by or on behalf of any Underwriter or any person
controlling any Underwriter, the Trust, the Advisor, their trustees, directors
or officers, or any person controlling the Trust or the Advisor, (ii) acceptance
of any Shares and payment therefor hereunder, and (iii) any termination of this
Agreement. A successor to any Underwriter or any person controlling any
Underwriter, or to the Trust, the Advisor, their trustees, directors or
officers, or any person controlling the Trust or the Advisor, shall be entitled
to the benefits of the indemnity, contribution, and reimbursement agreements
contained in this Section 8.

     9.   CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The several obligations of
the Underwriters to purchase the Firm Shares and the Option Shares, as the case
may be, hereunder are subject to the following conditions:

     (a)  If, at the time this Agreement is executed and delivered, it is
necessary for the registration statement or a post-effective amendment thereto
to be declared effective before the offering of the Shares may commence, the
registration statement or such post-effective amendment shall have become
effective not later than 5:30 P.M., New York City time, on the date hereof, or
at such later date and time as shall be consented to in writing by you, and all
filings, if any, required by Rules 497 and 430A under the 1933 Act and the 1933
Act Rules and Regulations shall have been timely made; no stop order suspending
the effectiveness of the Registration Statement or order pursuant to Section
8(e) of the 1940 Act shall have been issued and no proceeding for those purposes
shall have been instituted or, to the knowledge of the Trust, the Advisor or any
Underwriter, threatened by the Commission, and any request of the Commission for
additional information (to be included in the registration statement or the
prospectus or otherwise) shall have been complied with to your satisfaction.

     (b)  Subsequent to the effective date of this Agreement, there shall not
have occurred (i) any change or any development involving a prospective change
in or affecting the condition (financial or other), business, prospects,
properties, net assets, or results of operations of the Trust or the Advisor not
contemplated by the Prospectus, which in your opinion, as Representatives of the
several Underwriters, would materially adversely affect the market for the
Shares, or (ii) any event or development relating to or involving the Trust or
the Advisor or any officer or director of the Trust or the Advisor which makes
any statement made in the Prospectus


<PAGE>   21


                                                                              21



untrue or which, in the opinion of the Trust and its counsel or the Underwriters
and their counsel, requires the making of any addition to or change in the
Prospectus in order to state a material fact required by the 1933 Act, the 1940
Act or the Rules and Regulations or any other law to be stated therein or
necessary in order to make the statements therein not misleading, if amending or
supplementing the Prospectus to reflect such event or development would, in your
opinion, as Representatives of the several Underwriters, materially adversely
affect the market for the Shares.

     (c)  You shall have received on the Closing Date an opinion of Ropes &
Gray, counsel for the Trust, dated the Closing Date and addressed to you, as
Representatives of the several Underwriters, in form and substance satisfactory
to you and to the effect that:

          (i) The Trust has been duly organized and is validly existing and in
     good standing as an unincorporated voluntary association (commonly known as
     a Massachusetts business trust) under the laws of the Commonwealth of
     Massachusetts and has full power and authority to own, lease and operate
     its properties and to conduct its business as described in the Registration
     Statement and the Prospectus and to issue and sell the Shares as
     contemplated by this Agreement;

          (ii) The Shares have been duly authorized and, when issued and
     delivered to the Underwriters against payment therefor in accordance with
     the terms of this Agreement, will be validly issued, fully paid and, except

omitted to state any material fact required to be stated therein or necessary in
order to make the statements therein not misleading, or that as of the Closing
Date the Prospectus contained an untrue statement of material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading (in each case other than the financial statements and schedules,

     in breach or violation of any judgment, decree, order, rule or regulation
     of any court or governmental or self-regulatory agency or body;

          (v) Neither the execution, delivery or performance of the Underwriting
     Agreement, nor the consummation by the Advisor of the transactions
     contemplated hereby or thereby, (i) requires any consent, approval,

     of the Advisor pursuant to the terms of the Agreements and Instruments;

          (vi) The Adviser has the corporate power and authority to enter into
     this Agreement and the Management Agreement, and this Agreement and the
     Management Agreement have been duly authorized, executed and delivered by
     the Advisor; assuming due authorization, execution and delivery by the
     other parties thereto, the Underwriting Agreement and the Management
     Agreement each constitutes the valid and binding obligation of the Advisor
     enforceable in accordance with its terms (except as rights to indemnity and
     contribution in this Agreement and the Management Agreement may be limited
     by Federal or state securities laws), subject as to enforcement to
     bankruptcy, insolvency, moratorium, reorganization and other laws of

     general equity principles (regardless of whether enforceability is
     considered in a proceeding in equity or at law); and

     Advisor's investment decisions, beliefs and strategies regarding the
     Trust's portfolio as to which such counsel need express no opinion) in the
     Registration Statement and the Prospectus (including the Statement of
     Additional Information) does not contain an untrue statement of a material
     fact or omit to state a material fact required to be stated therein or
     necessary to make the statements therein, in light of the circumstances
     under which they were made, not misleading.

     Such counsel may also state, in substantially the same form, that:

     She has not independently verified the accuracy, completeness or fairness
of the statements made or the information contained in the Registration
Statement or the Prospectus, and, except for the information referred to in
paragraph (vii) above, she is not passing upon and does not assume any
responsibility therefor.

     11.  EFFECTIVE DATE OF AGREEMENT. This Agreement shall become effective:
(i) upon the execution and delivery hereof by the parties hereto; or (ii) if, at
the time this Agreement is executed and delivered, it is necessary for the
registration statement or a post-effective amendment thereto to be declared
effective before the offering of the Shares may commence, when notification of
the effectiveness of the registration statement or such post-effective amendment
has been released by the Commission. Until such time as this Agreement shall
have become effective, it may be terminated by the Trust, by notifying you, or
by you, as Representatives of the several Underwriters, by notifying the Trust.

     If any one or more of the Underwriters shall fail or refuse to purchase
Shares which it or they are obligated to purchase hereunder on the Closing Date,
and the aggregate number of Shares which such defaulting Underwriter or
Underwriters are obligated but fail or refuse to purchase is not more than
one-tenth of the aggregate number of Shares which the



<PAGE>   29


                                                                              29



Underwriters are obligated to purchase on the Closing Date, each non-defaulting
Underwriter shall be obligated, severally, in the proportion which the number of
Firm Shares set forth opposite its name in Schedule I hereto bears to the
aggregate number of Firm Shares set forth opposite the names of all
non-defaulting Underwriters or in such other proportion as you may specify, to
purchase the Shares which such defaulting Underwriter or Underwriters are
obligated, but fail or refuse, to purchase. If any one or more of the
Underwriters shall fail or refuse to purchase Shares which it or they are
obligated to purchase on the Closing Date and the aggregate number of Shares
with respect to which such default occurs is more than one-tenth of the
aggregate number of Shares which the Underwriters are obligated to purchase on
the Closing Date and arrangements satisfactory to you and the Trust for the
purchase of such Shares by one or more non-defaulting Underwriters or other
party or parties approved by you and the Trust are not made within 36 hours
after such default, this Agreement will terminate without liability on the part
of any non-defaulting Underwriter or the Trust. In any such case which does not
result in termination of this Agreement, either you or the Trust shall have the
right to postpone the Closing Date, but in no event for longer than seven days,
in order that the required changes, if any, in the Registration Statement and
the Prospectus or any other documents or arrangements may be effected. Any
action taken under this paragraph shall not relieve any defaulting Underwriter
from liability in respect of any such default of any such Underwriter under this
Agreement. The term "Underwriter" as used in this Agreement includes, for all
purposes of this Agreement, any party not listed in Schedule I hereto who, with
your approval and the approval of the Trust, purchases Shares which a defaulting
Underwriter is obligated, but fails or refuses, to purchase.

     Any notice under this Section 11 may be given by telegram, telecopy or
telephone but shall be subsequently confirmed by letter.

     12.  TERMINATION OF AGREEMENT. This Agreement shall be subject to
termination in your absolute discretion, without liability on the part of any
Underwriter to the Trust or the Advisor, by notice to the Trust or the Advisor,
if prior to the Closing Date or any Option Closing Date (if different from the
Closing Date and then only as to the Option Shares), as the case may be, (i)
trading in securities generally on the New York Stock Exchange, the American
Stock Exchange or the Nasdaq National Market shall have been suspended or
materially limited, (ii) a general moratorium on commercial banking activities
in New York shall have been declared by either federal or state authorities, or
(iii) there shall have occurred any outbreak or escalation of hostilities or
other international or domestic calamity, crisis or change in political,
financial or economic conditions, the effect of which on the financial markets
of the United States is to make it, in your judgment, impracticable or
inadvisable to commence or continue the offering of the Shares at the offering
price to the public set forth on the cover page of the Prospectus or to enforce
contracts for the resale of the Shares by the Underwriters. Notice of such
termination may be given to the Trust by telegram, telecopy or telephone and
shall be subsequently confirmed by letter.

     13.  INFORMATION FURNISHED BY THE UNDERWRITERS. The statements set forth in
the last sentence of the last paragraph of the front cover page in the

                   COLONIAL CALIFORNIA INSURED MUNICIPAL FUND

                             SUBSCRIPTION AGREEMENT

     This Agreement made this 25th day of October, 1999 by and between Colonial
California Insured Municipal Fund, a Massachusetts business trust (the "Fund"),
and Colonial Management Associates, Inc., a Massachusetts corporation (the
"Subscriber");

     WITNESSETH:

     WHEREAS, the Fund has been formed for the purposes of carrying on business
as a closed-end non-diversified management investment company; and

     WHEREAS, the Subscriber has been selected by the Fund's Board of Trustees
to serve as investment adviser to the Fund; and

     WHEREAS, the Subscriber wishes to subscribe for and purchase, and the Fund
wishes to sell to the Subscriber, 6,667 common shares of beneficial interest for
a purchase price of $15.00 per share;

     NOW THEREFORE, IT IS AGREED:

     1.   The Subscriber subscribes for and agrees to purchase from the Fund
6,667 common shares of beneficial interest for a purchase price of $15.00 per
share. Subscriber agrees to make payment for these shares at such time as demand
for payment may be made by an officer of the Fund.

     2.   The Fund agrees to issue and sell said shares to Subscriber promptly
upon its receipt of the purchase price.

     3.   To induce the Fund to accept its subscription and issue the shares
subscribed for, the Subscriber represents that it is informed as follows:

          (a)  That the shares being subscribed for have not been and will not
be registered under the Securities Act of 1933 ("Securities Act");

          (b)  That the shares will be sold by the Fund in reliance on an
exemption from the registration requirements of the Securities Act;

          (c)  That the Fund's reliance upon an exemption from the registration
requirements of the Securities Act is predicated in part on the representations
and agreements contained in this Subscription Agreement;


<PAGE>   2



          (d)  That when issued, the shares will be "restricted securities" as
defined in paragraph (a)(3) of Rule 144 of the General Rules and Regulations
under the Securities Act ("Rule 144") and cannot be sold or transferred by
Subscriber unless they are subsequently registered under the Securities Act or
unless an exemption from such registration is available;

          (e)  That there do not appear to be any exemptions from the
registration provisions of the Securities Act available to the Subscriber for
resale of the shares. In the future, certain exemptions may possibly become
available, including an exemption for limited sales including an exemption for
limited sales in accordance with the conditions of Rule 144.

     The Subscriber understands that a primary purpose of the information
acknowledged in subparagraphs (a) through (e) above is to put it on notice as to
restrictions on the transferability of the shares.

     4.   To further induce the Fund to accept its subscription and issue the
shares subscribed for, the Subscriber:

          (a)  Represents and warrants that the shares subscribed for are being
and will be acquired for investment for its own account and not on behalf of any
other person or persons and not with a view to, or for sale in connection with,
any public distribution thereof; and

          (b)  Agrees that any certificates representing the shares subscribed
for may bear a legend substantially in the following form:

          The shares represented by this certificate have been acquired for
          investment and have not been registered under the Securities Act of
          1933 or any other federal or state securities law. These shares may
          not be offered for sale, sold or otherwise transferred unless
          registered under said securities laws or unless some exemption from
          registration is available.

     5.   This Subscription Agreement and all of its provisions shall be binding
upon the legal representatives, heirs, successors and assigns of the parties
hereto.

     6.   The Fund's Declaration of Trust is on file with the Secretary of the
Commonwealth of Massachusetts. This Agreement is executed on behalf of the Fund
by the Fund's officers as officers and not individually and the obligations
imposed upon the Fund by this Agreement are not binding upon any of the Fund's
Trustees, officers or shareholders individually but are binding only upon the
assets and property of the Fund.
