to approve each item is described under "Miscellaneous."

The Board has fixed the close of business on July 15, 1999 as the record date

Pursuant to the Amended and Restated Agreement and Declaration of Trust of the
Fund, the Board may authorize separate classes of shares of beneficial interest.
The Board has authorized, and the Fund has issued, common shares of beneficial
interest (the "Common Shares") and preferred shares of beneficial interest,
Series A through D (the "Preferred Shares"). The Common Shares and the Preferred
Shares have different powers, rights, preferences and privileges,
qualifications, limitations and restrictions with respect to, among other
things, dividends, liquidation, redemption and voting as more fully set forth in
the Certificate of Designation for Preferred Shares that established the
Preferred Shares. The Common Shares were first issued on October 20, 1988 and
the Preferred Shares were first issued on July 24, 1989. At the Meeting, the
holders of the Preferred Shares, voting as a separate class, are entitled to
elect two members of the Board and the holders of the Common Shares and the
Preferred Shares, voting together as a single class, are entitled to elect the
five remaining members of the Board. On Item 2, the holders of the Common Shares
and the Preferred Shares will vote together as a single class. On Item 3, only
the holders of the Preferred Shares will vote, each series voting as a separate
class.

ITEM 1. ELECTION OF TRUSTEES TO THE BOARD

THE BOARD RECOMMENDS THAT YOU VOTE FOR THE ELECTION OF THE NOMINEES NAMED BELOW.

It is intended that the proxies will be voted for the election as Trustees of
the nominees described below. Each Trustee so elected will serve as a Trustee of
the Fund until the next meeting of shareholders, if any, called for the purpose
of electing Trustees and until the election and qualification of a successor or
until such Trustee sooner dies, resigns or is removed as provided in the
organizational documents of the Fund. All the

                                        2
<PAGE>   4

nominees, except James R. Edgar, were last elected to the Board at the 1998
annual meeting of the shareholders. Mr. Edgar was appointed to the Board on May
27, 1999 and will be standing for election by shareholders for the first time.

As indicated above, holders of the Preferred Shares are entitled to elect two
Trustees. Messrs. Kelsey and Littauer are nominees for election by holders of
the Preferred Shares. In addition, five other Trustees are to be elected by
holders of the Common Shares and the Preferred Shares, voting together as a
single class. Messrs. Akins, Edgar, Gottschalk, Renwick, and Weithers are
nominees for election by all shareholders.

All the nominees listed below have consented to serve as Trustees of the Fund,
if elected. In case any nominee shall be unable or shall fail to act as a
Trustee by virtue of an unexpected occurrence, the proxies may be voted for such
other person(s) as shall be determined by the persons acting under the proxies
in their discretion.

 * Interested person of the Fund as defined in the Investment Company Act of
   1940 ("1940 Act").

** From time to time, the Trustees have been, and may in the future be,
   restricted from buying and/or selling shares of the Fund.

All the nominees, except Mr. Littauer, serve as board members of 16 investment
companies, with 56 portfolios managed by Scudder Kemper Investments, Inc. (the
"Adviser"). Mr. Littauer serves as a board member of various investment
companies managed by the Adviser.

The Board has an audit and governance committee that is composed of Messrs.
Akins, Edgar, Gottschalk, Kelsey, Renwick, and Weithers. The committee met six
times during its 1998 fiscal year (November 30, 1998). The committee makes
recommendations regarding the selection of independent auditors for the Fund,
confers with the independent auditors regarding the Fund's financial statements,
the results of audits and related matters, seeks and reviews nominees for Board
membership and performs such other tasks as the Board assigns. The committee
also

                                        5
<PAGE>   7

proposes the nominees for election by the shareholders. Shareholders wishing to
submit the name of a candidate for consideration by the committee should submit
their recommendations to the secretary of the Fund.

The Fund pays Trustees who are not "interested persons" of the Fund an annual
retainer plus expenses, and an attendance fee for each Board meeting and
committee meeting attended. As reflected above, the Trustees currently serve as
board members of various investment companies for which the Adviser serves as
investment manager. Trustees or officers of the Fund who are "interested
persons" receive no compensation from such Fund. The Board of the Fund met six
times during its 1998 fiscal year. Each then current Trustee attended 75% or
more of the meetings of the Board and the audit and governance committee (if
then a member thereof) held during its 1998 fiscal year.

The table shows, for each Trustee entitled to receive compensation from the
Fund, the aggregate compensation paid or accrued during the Fund's 1998 fiscal
year and the total compensation that the Kemper funds paid or accrued during
calendar year 1998.

    (including interest thereon) payable from the Fund is $          .

(3) Includes compensation for service on the boards of 15 Kemper Funds with 50

FUND OFFICERS. Information about the executive officers of the Fund, with their
respective dates of birth, terms as Fund officers indicated and principal
occupation for the past five years, is set forth below.

Mark S. Casady (9/21/60), president of the Fund since 1/21/98, is managing
director of the Adviser.

<PAGE>   8

Philip J. Collora (11/15/45), vice president of the Fund since 2/1/90 and
secretary of the Fund since 3/2/95. Mr. Collora is senior vice president of the
Adviser.

John R. Hebble (6/27/59), treasurer of the Fund since 5/20/98, is senior vice
president of the Adviser.

Ann M. McCreary (11/6/56), vice president of the Fund since 1/21/98, is managing
director of the Adviser.

Caroline Pearson (4/1/62), has been an assistant secretary of the Fund since
1/21/98. Ms. Pearson is a senior vice president of the Adviser; formerly,
Associate, Dechert Price & Rhodes (law firm) 1989 to 1997.

Robert C. Peck, Jr. (10/1/46), vice president of the Fund since 1/21/98, is
managing director of the Adviser; prior to 8/2/97, he was executive vice
president and chief investment officer with an unaffiliated investment
management firm.

Kathryn L. Quirk (12/3/52), vice president of the Fund since 1/21/98, is
managing director of the Adviser.

The officers of the Fund are elected by the Board of the Fund on an annual basis
to serve until their successors are elected and qualified.

SHAREHOLDERS. As of April 30, 1999, the Trustees and officers of the Fund as a
group owned beneficially           shares, which is less than 1% of the
outstanding shares of each Fund. As of April 30, 1999, no person is known to the
Fund to have owned beneficially more than 5 percent of the shares of the Fund.

SECTION 16 REPORTING COMPLIANCE. Section 30(h) of the 1940 Act and Section 16(a)
of the Securities Exchange Act of 1934 require the Fund's officers and Trustees,
the Adviser, affiliated persons of the Adviser and persons who own more than ten
percent of a registered class of the Fund's equity securities to file forms
reporting their affiliation with that Fund and reports of ownership and changes
in ownership of that Fund's shares with the Securities and Exchange Commission
(the "SEC") and the New York Stock Exchange (the "NYSE"). These persons and
entities are required by SEC regulation to furnish the Fund with copies of all
Section 16(a) forms they file. Based solely upon its review of the copies of
each form received by it, and written representations from certain reporting
persons that no year-end reports were required for those persons, the Fund
believes that during the fiscal year ended November 30, 1998, such reporting
persons complied with all applicable filing requirements.

INVESTMENT MANAGER. Scudder Kemper Investments, Inc. (the "Adviser"), 345 Park
Avenue, New York, NY 10154, serves as the Fund's investment adviser and manager
pursuant to an investment management agreement.

ITEM 2. SELECTION OF INDEPENDENT AUDITORS

THE BOARD OF EACH FUND RECOMMENDS THAT YOU VOTE FOR THE RATIFICATION OF ERNST &
YOUNG LLP AS INDEPENDENT AUDITORS FOR EACH FUND.

A majority of the Trustees who are "non-interested" persons of the Fund has
selected Ernst & Young LLP, independent auditors, to audit the books and records
of the Fund for the current fiscal year. This firm has served the Fund in this
capacity since the Fund was organized and has no direct or indirect financial
interest in the Fund except as independent auditors. The selection of Ernst &
Young LLP as independent auditors of the Fund is being submitted to the
shareholders for ratification. A representative of Ernst & Young LLP is expected
to be present at the Meeting and will be available to respond to any appropriate
questions raised at the Meeting and may make a statement.

ITEM 3. AMENDED AND RESTATED CERTIFICATE OF DESIGNATION FOR PREFERRED SHARES

THE BOARD RECOMMENDS THAT YOU VOTE FOR THE AMENDED AND RESTATED CERTIFICATE OF
DESIGNATION FOR PREFERRED SHARES

The proposed Amended and Restated Certificate of Designation for Preferred
Shares (the "Amended and Restated Certificate of Designation") would make
certain changes to the terms of the Certificate of Designation for Preferred
Shares (the "Certificate of Designation") in order to provide greater
flexibility, to refine the terms and conditions in light of subsequent positions
taken by the Internal Revenue Service ("IRS") and to update certain terms to
bring them into conformity with recent developments in the marketplace for
closed-end fund preferred shares, including the current standards for rating
such shares.

The Amended and Restated Certificate of Designation would (1) allow the Board of
Trustees, without shareholder approval, to issue additional series of preferred
shares, subject to compliance with the applicable 1940 Act asset coverage
requirements and rating agency approval and (2) amend various sections of the
Certificate of Designation as described below. The following summary of the
Amended and Restated Certificate of Designation set forth below is qualified in
its entirety by reference to the Amended and Restated Certificate of Designation
for Preferred Shares, a copy of which, marked to show changes from the
Certificate of Designation adopted on July 25, 1989, is attached as Annex A.
Capitalized terms not defined will have the same meaning as these terms are used
in the Amended and Restated Certificate of Designation.

                                        8
<PAGE>   10

(1) ELIMINATION OF "SUNSET" PROVISIONS.

     The Certificate of Designation requires the mandatory redemption by the
Fund of each series of Preferred Shares beginning in 2020 for Series A and at
two-year intervals thereafter for each successive series. The Amended and
Restated Certificate of Designation would eliminate these provisions. Subsequent
IRS pronouncements have made such provisions inadvisable for preferred shares.

(2) AMENDMENT TO VOTING REQUIREMENTS.

     (A) SERIES BY SERIES VOTING.

     The Certificate of Designation currently provides that preferred
shareholders have the right to vote together as a class on certain matters as
required by the 1940 Act. The current Certificate of Designation, however, does
not provide for series by series voting of the Preferred Shares on matters that
affect only that series. The Amended and Restated Certificate of Designation
would provide that series by series voting is required only on those matters
that affect that series in a manner different from that of other series or
classes of the Fund's shares.

     (B) ABILITY TO ISSUE ADDITIONAL PREFERRED SHARES OF A NEWLY CREATED SERIES
         WITHOUT SHAREHOLDER APPROVAL.

     The current Certificate of Designation requires approval of preferred
shareholders to increase or decrease the number of Preferred Shares authorized
to be issued. The Amended and Restated Certificate of Designation would continue
to provide that preferred shareholder approval is required to increase or
decrease the number of Preferred Shares of a previously designated series
authorized to be issued. However, the Amended and Restated Certificate of
Designation would give the Board of Trustees the ability to establish and
designate additional series of Preferred Shares, without shareholder approval,
provided that (1) if the Preferred Shares are rated by Moody's Investors
Service, Inc. ("Moody's") or Standard & Poor's, a division of the McGraw Hill
Companies ("S&P"), the Fund obtains written confirmation from Moody's or S&P
that the issuance of such additional shares or other class or series of shares
would not impair the rating then assigned by such rating agency to any series of
the Preferred Shares outstanding or (2) if Moody's or S&P is not then rating the
Preferred Shares, the aggregate liquidation preference of all Preferred Shares
of the Fund outstanding after any such issuance, exclusive of accumulated and
unpaid dividends, may not exceed $           .

     The Amended and Restated Certificate of Designation, by giving the Board
the authority to issue additional shares of newly created series, enables the
Fund to manage its capital structure more efficiently in

                                        9
<PAGE>   11

response to changing market conditions. Issuing additional Preferred
Shares, however, would decrease the amount of asset coverage for existing
Preferred Shares.

     On [May 19, 1999], the Board approved the issuance of an additional $50
million of Preferred Shares of a newly created Series E, contingent upon
shareholders approving the Amended and Restated Certificate of Designation. The
Amendment provides for the establishment and designation of Series E. The Fund
believes that the ceiling amount of $           (the amount of both the
Preferred Shares currently outstanding and the proposed additional Preferred
Shares of Series E) will adequately protect existing holders of Preferred Shares
in the event the Fund issues additional Preferred Shares at a time when neither
Moody's nor S&P is rating the Fund's Preferred Shares. In addition, so long as
either Moody's or S&P is rating the Preferred Shares and the Fund is
required--as a precondition for issuing additional Preferred Shares--to obtain
written confirmation for each rating agency then rating the Preferred Shares so
that any such additional issuance would not impair the rating then assigned to
the Preferred Shares by such rating agency, the Fund believes that holders of
Preferred Shares will be adequately assured that any such additional issuance
will not result in any significant diminution of the Fund's overall
creditworthiness.

(3) CHANGE IN ALLOCATION OF TAXABLE INCOME AND "GROSS UP PAYMENTS"

     The IRS currently requires that a regulated investment company that has two
or more classes of shares must designate to each such class proportionate
amounts of each type of its income for each tax year based upon the percentage
of total dividends distributed to each class for such year. Under a special
"grandfather" provision contained in Revenue Ruling 89-81, certain regulated
investment companies with Preferred Shares outstanding prior to June 13, 1989,
can make non-proportionate designations. The Fund has designated exempt-interest
dividends disproportionately to Preferred Shares and designated capital gains
and any ordinary income to its common shares pursuant to this "grandfather"
provision. The issuance of additional Preferred Shares of newly created Series E
approved by the Board may result in the Fund not being allowed to rely on the
"grandfather" provision.

     Therefore, the Amended and Restated Certificate of Designation provides
that the Fund would be obligated to provide advance notice of any potentially
taxable portion of any dividend distributions to preferred shareholders to the
remarketing agent prior to the setting of the dividend rate for a particular
dividend period to permit the remarketing process to consider this potentially
taxable amount payable during the next dividend period in setting the return on
the Preferred Shares for that period. If the Fund fails to provide such advance
notice, the Fund

                                       10
<PAGE>   12

would be obligated (under certain conditions) to make a "gross up
payment" to preferred shareholders in respect of the tax payable on taxable
income received.

     Under the "gross up" provisions of the Amended and Restated Certificate of
Designation, the Fund would make "gross up" payments to offset any such
allocation of taxable income and capital gains to preferred shareholders if, in
the case of any Dividend Period of 28 days or fewer, the Fund allocates any net
capital gains or other income taxable for Federal income tax purposes to a
dividend paid on the Preferred Shares without having given advance notice
thereof to the Remarketing Agent ("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 Preferred Shares or the liquidation of the
Fund. If, in the case of any Dividend Period of more than 28 days, the Fund
makes a Taxable Allocation to a dividend paid on the Preferred Shares, the Fund
shall, prior to the end of the calendar year in which each dividend was paid,
provide notice thereof to the Remarketing Agent and direct the Funds' dividend
disbursing agent for the Preferred Shares 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 Fund. A "gross up payment" means payment to
a holder of preferred shares of an amount that, when taken together with the
aggregate amount of Taxable Allocations made to such holder to which such gross
up payment relates, would cause such holder's dividend in dollars (after Federal
income tax consequences) from the aggregate of such Taxable Allocations and the
related gross up payment to be equal to the dollar amount of the dividends that
would have been received by such holder if the amount of the aggregate Taxable
Allocations were not subject to regular Federal income tax.

(4) AUTHORITY OF THE BOARD TO INTERPRET THE CERTIFICATE OF DESIGNATION.

     From time to time, issues may arise with respect to the preferred shares
that require interpretation or adjustment of certain provisions of the
Certificate of Designation. These issues may range from ambiguities in terms
used to formal defects. In order to facilitate any future interpretations of the
Certificate of Designation, the Amended and Restated Certificate of Designation
would explicitly recognize the Board's authority, to the extent permitted by
applicable law, to interpret such matters and, if necessary, adjust the language
of the Amended and Restated Certificate of Designation. In addition, the Amended
and Restated Certificate of Designation would explicitly give the Board the
authority to amend the Certificate of Designation with respect to any series of
Preferred Shares prior to the issuance of shares of such series.

(5) MISCELLANEOUS PROVISIONS TO COMPLY WITH S&P AND MOODY'S RATING CRITERIA

     Because it is expected that any future issuance of Preferred Shares,
including the proposed shares of Series E discussed above, would be rated by S&P
and/or Moody's, the Amended and Restated Certificate of Designation for
Preferred Shares contains various changes designed to conform the Amended and
Restated Certificate of Designation to current ratings criteria and drafting
conventions. The primary thrust of these changes is to identify specifically the
"Rating Agency Required Asset Coverage," in accordance with current rating
agency guidelines. This language reflects the rating agency requirement that
certain eligible Fund assets must have a discounted value at least equal to the
liquidation value of the outstanding preferred shares plus unpaid dividends and
certain other Fund liabilities.

MISCELLANEOUS

GENERAL. The cost of preparing, printing and mailing the enclosed proxy,
accompanying notice and proxy statement and all other costs in connection with
solicitation of proxies will be paid by the Fund, including any additional
solicitation made by letter, telephone or facsimile. In addition to solicitation
by mail, certain officers and representatives of the Fund, officers and
employees of the Adviser and certain financial services firms and their
representatives, who will receive no extra compensation for their services, may
solicit proxies by telephone, telegram or personally. The Fund has engaged
Shareholder Communications Corporation to assist in the solicitation of proxies
at a total estimated cost of $3,500 (plus expenses). Failure of a quorum to be
present at the Meeting for the Fund will necessitate adjournment for the Fund
and will subject the Fund to additional expense. A COPY OF THE FUND'S ANNUAL
REPORT IS AVAILABLE WITHOUT CHARGE UPON REQUEST BY WRITING TO THE FUND, 222
SOUTH RIVERSIDE PLAZA, CHICAGO, ILLINOIS 60606 OR BY CALLING 1-800-294-4366.

PROPOSALS OF SHAREHOLDERS. The Fund delayed its 1999 annual meeting of
shareholders from May to September. It is currently anticipated that the 2000
annual meeting will be held in May. A shareholder wishing to submit a proposal
for inclusion in the Fund's proxy statement for the 2000 annual meeting of
shareholders pursuant to Rule 14a-8 under the Securities Exchange Act of 1934
should send such written proposal to the Secretary of the Fund within a
reasonable time before the solicitation of proxies for such meeting. The Fund
will treat any such proposal received no later than December 17, 1999 as timely.
A shareholder wishing to provide notice in the manner prescribed by Rule
14a-4(c)(1) to the Fund of a proposal submitted outside of the process of Rule
14a-8 must submit such written notice to the Secretary of the Fund within a
reasonable time before the solicitation of proxies for such meeting. The Fund
will treat any such notice

                                       12
<PAGE>   14

received no later than February 25, 2000 as timely. The timely submission of a
proposal under either rule, however, does not guarantee its inclusion.

OTHER MATTERS TO COME BEFORE THE MEETING. The Board is not aware of any matters
that will be presented for action at the Meeting other than those set forth
herein. Should any other matters requiring a vote of shareholders arise, the
proxy in the accompanying form will confer upon the person or persons entitled
to vote the shares represented by such proxy the discretionary authority to vote
the shares with respect to any such other matters in accordance with their best
judgment in the interest of the Fund.

VOTING, QUORUM. Each valid proxy will be voted in accordance with the
instructions on the proxy and as the persons named in the proxy determine on
such other business as may come before the Meeting. If no instructions are
given, the proxy will be voted for the election as Trustees of the persons who
have been nominated for the Fund and as recommended by the Board on each other
item. Shareholders who execute proxies may revoke them at any time before they
are voted, either by writing to the Fund or in person at the time of the
Meeting. Proxies given by telephone or electronically transmitted instruments
may be counted if obtained pursuant to procedures designed to verify that such
instructions have been authorized. Item 1, election of Trustees, requires a
plurality vote of the shares of the Fund. As noted previously, the holders of
the Preferred Shares, voting as a separate class, are entitled to elect two
Members of the Board and the holders of the Common Shares and the Preferred
Shares, voting together as a single class, are entitled to elect the five
remaining Members of the Board. With regard to Item 2, ratification of the
selection of independent auditors for the Fund, the holders of the Common Shares
and the Preferred Shares of the Fund will vote together as a single class, and
requires the affirmative vote of a majority of the shares of the Fund voting on
the matter. Item 3, approval of the Amended and Restated Certificate of
Designation, requires the affirmative vote of a majority of the outstanding
Preferred Shares, each series voting as a separate class. Preferred Shares held
in "street name" for which voting instructions have not been received as of one
business day before the meeting, or if adjourned, one business day before the
day to which the meeting is adjourned, and that would otherwise be treated as
"broker non-votes" may, pursuant to Rule 452 of the NYSE, be voted by the broker
on Item 3 in the same proportion as the votes cast by all Preferred Shares who
voted on the item. Rule 452 permits proportionate voting for Preferred Shares
with respect to a particular item if, among other things, (i) a minimum of 30%
of the Preferred Shares outstanding has been voted by the holders of such shares
with respect to the item and (ii) less than 10% of the Preferred Shares
outstanding has been voted by the holders of such shares against the item. For
the purpose of meeting the 30% test, abstentions will be treated as shares
"voted" and, for the purpose of meeting the 10% test, abstentions will not be
treated as shares "voted" against the item. On Item 1, abstentions and broker
non-votes will have no effect; the persons

                                       13
<PAGE>   15

receiving the largest number of votes will be elected. On Item 2, abstentions
and broker non-votes will not be counted as votes cast and will have no effect
on the result of the vote.

At least 50% of the shares of the Fund must be present, in person or by proxy,
in order to constitute a quorum for that Fund. Thus, the meeting for the Fund
could not take place on its schedule date if less than 50% of the shares of the
Fund were represented.

THE BOARD OF THE FUND RECOMMENDS AN AFFIRMATIVE VOTE ON ALL ITEMS.

PLEASE COMPLETE, SIGN AND RETURN THE ENCLOSED PROXY PROMPTLY. NO POSTAGE IS
REQUIRED IF MAILED IN THE UNITED STATES.

By order of the Board,
Philip J. Collora
Secretary

by the Board of Trustees out of funds available therefor, at the rates, on the
dates, for the periods and otherwise in the manner provided in this paragraph 3.

          (a) Initial Dividend Periods and Dividend Rates. The initial Dividend
     Period and the Dividend Rate and Dividend Payment Date therefor for each

     Preferred Shares of a series shall have a 28-day Dividend Period subject to
     the following adjustments: (i) if a Dividend Period ends on a day which is
     not immediately preceding a Business Day, such Dividend Period shall end on
     the next day which immediately precedes a Business Day and the subsequent
     Dividend Period shall be decreased by the number of days by which such
     preceding Dividend Period was increased; (ii) with respect to a Dividend
     Period which is not a Seven-Day Dividend Period and which was immediately
     preceded by one or more Seven-Day Dividend Periods, such Dividend Period
     shall be decreased or increased by the smallest number of days, if any,
     necessary for such Dividend Period to end on the day such Dividend Period

     from time to time, subject to the requirements of (i) and (ii) above,
     adjust the normal 28-day Dividend Period for a series of Preferred Shares
     to a period not less than seven days nor more than 30 days to assist in the
     remarketing process and such Dividend Period shall, as soon as possible
     within the limits set forth herein, thereafter be adjusted so as to return
     to the normal 28-day Dividend Period ending on the day it would have ended
     had no adjustment been made.

          Each Dividend Period for each series of Preferred Shares during a
     Non-Payment Period in respect of a series of Preferred Shares shall be,
     automatically, a Seven-Day Period. If, for any reason, (i) the Remarketing

                                      A-15
<PAGE>   31

     remarketed at $5,000 on the day of its tender, all Preferred Shares of that
     series will have successive Seven-Day Dividend Periods until the next
     Dividend Period on the first day of which all Preferred Shares of that
     series tendered for remarketing have been remarketed. Upon giving of notice
     of redemption of any Preferred Share, each subsequent Dividend Period for
     such Preferred Share shall end on or prior to the day next preceding the
     redemption date therefor.

          (c) Subsequent Dividend Rates. Subsequent to its initial Dividend
     Period, (A) the Dividend Rate for each Preferred Share of a series during
     each Dividend Period in respect of such series which is not a Seven-Day
     Dividend Period shall be the Dividend Rate, which shall not exceed the
     Maximum Rate, established for such Dividend Period for such Preferred Share
     by the Remarketing Agent in the manner provided herein and (B) the Dividend
     Rate for each Preferred Share of a series during a Seven-Day Dividend
     Period which is not during a Non-Payment Period shall be the Maximum Rate
     and the Dividend Rate for each Preferred Share of a series during a
     Seven-Day Dividend Period which is during a Non-Payment Period shall be the
     Non-Payment Rate.

          (d) Determination of Dividend Periods and Rates for Remarketed
     Preferred Shares. Subject to clauses (a), (b) and (c) of this paragraph 3,
     the Remarketing Agent for each Preferred Share shall establish (i) a
     Dividend Period for Preferred Shares, Series A; Preferred Shares, Series B;
     Preferred Shares, Series C; Preferred Shares, Series D and Preferred
     Shares, Series E of 28 days, and (ii) that Dividend Rate (which shall not
     exceed the Maximum Rate) for each Dividend Period for each such series
     which it shall determine would be the rate, but no higher than the rate,
     which would permit all of the Preferred Shares of such series to be
     remarketed at $5,000 per Preferred Share. In establishing each Dividend
     Rate, the Remarketing Agent shall take into account the following factors
     ("Remarketing Conditions"): (i) short-term and long-term market rates and
     indices of such short-term and long-term rates, (ii) market supply and
     demand for short-term and long-term securities, (iii) yield curves for
     short-term and long-term securities comparable to the Preferred Shares,
     (iv) industry and financial conditions which may affect the Preferred
     Shares, (v) the number of Preferred Shares to be remarketed, (vi) the
     number of potential purchasers, (vii) if the Fund has notified the
     Remarketing Agent of its intent to allocate income taxable for Federal
     income tax purposes to the Preferred Shares prior to the determination of
     the Dividend Rate for that Dividend Period, the effect of any Federal
     income tax on the allocated income at the highest rate applicable to
     corporations or

                                      A-16
<PAGE>   32

     individuals, whichever is greater, and (viii) the Dividend Rate at which
     current and potential Owners would remain or become Owners.

          (e) Certificate of Determination. On each day on which any series of
     Preferred Shares shall begin a new Dividend Period, the Board of Trustees
     or its delegate shall approve the Dividend Period and the Dividend Rate
     therefor and a Certificate of Determination setting forth such Dividend
     Period and Dividend Rate shall be prepared and executed by a trustee, the
     president, any vice president, the treasurer, any assistant treasurer, the
     secretary or any assistant secretary of the Fund. In preparing a
     Certificate of Determination, the Dividend Period and the Dividend Rate of
     Preferred Shares of a series shall be as established by the Remarketing
     Agent.

          (f) Computation of Dividends. Each Dividend Rate shall be expressed as
     a percentage per annum. Dividends in respect of each series of Preferred
     Shares shall be payable on each Dividend Payment Date for such series of
     Preferred Shares, for the Dividend Period commencing on the Dividend
     Payment Date immediately preceding such Dividend Payment Date and ending on
     the day immediately preceding such Dividend Payment Date, in an amount
     equal to $5,000 multiplied by the Dividend Rate applicable to such Dividend
     Period for such series of Preferred Shares. Dividends shall be calculated
     on the basis of a year of 365/366 days for the actual number of days
     elapsed.

          (g) Payment of Dividends. (i) Current Dividends. Not later than 12:00
     noon, New York City time on the Business Day immediately preceding each
     Dividend Payment Date for each series of Preferred Shares, the Fund, to the
     extent it shall have funds available therefor out of income earned on the
     Fund's investments, shall deposit with the Paying Agent sufficient funds
     for the payment of the dividend, if declared, on such series of Preferred
     Shares payable on such Dividend Payment Date, together with irrevocable
     instructions to the Paying Agent to apply such funds and the proceeds
     therefrom to the payment of such dividend on such Dividend Payment Date
     and, if the Stock Register shall not be maintained by the Paying Agent,
     together with instructions relating to the manner of payment and the
     addresses of the Owners to whom payment is to be made. Each such dividend
     shall be paid to the Owner of each Preferred Share of such series as of the
     close of business on the record date therefor, which shall be the fifth day
     preceding such Dividend Payment Date. Nevertheless, no dividends shall be
     declared or paid on any Dividend Payment Date for any series of Preferred
     Shares, unless full cumulative dividends on all Preferred Shares payable on
     all Dividend Payment Dates prior to or

                                      A-17
<PAGE>   33

     concurrent with such Dividend Payment Date shall have been or
     contemporaneously shall be declared and paid or funds for the payment
     thereof set apart with the Paying Agent. In addition, dividends on
     Preferred Shares will be designated as exempt-interest dividends up to the
     amount of tax-exempt income of the Fund for purposes of section 852 of the
     Code; provided, however, that to the extent required under the Code, the
     Fund shall designate such dividends as exempt-interest and capital gain
     dividends (with the amount not so designated to be treated as taxable
     income) in the amounts required under the Code. In addition, dividends on
     Preferred Shares will be designated as exempt-interest dividends up to the
     proportionate amount of tax-exempt income of the Fund allocable to the
     Preferred Shares for purposes of Section 852 of the Code; provided,
     however, that to the extent required under the Code, the Fund shall
     designate such dividends as exempt-interest and capital gain dividends
     (with the amount not so designated to be treated as taxable income) in the
     amounts required under the Code.

          (ii) Dividends in Arrears. Dividends in arrears for any past Dividend
     Period may be declared by the Board of Trustees and paid on any date fixed
     by the Board of Trustees, whether or not a regular Dividend Payment Date,
     to the Owners of Preferred Shares on the record date therefor, which shall
     not be more than 15 days before such Dividend Payment Date, as may be fixed
     by the Board of Trustees. If all dividends in arrears on all Preferred
     Shares have not been declared and paid, or funds for the payment thereof
     set apart, payment of dividends in arrears shall be made in order of
     Dividend Payment Dates, commencing with the earliest as provided below. If
     the amount of any such payment does not fully provide for all dividends in
     arrears, any such payment shall be applied in the manner described in the
     preceding sentence, and with respect to any Dividend Payment Date as to
     which all dividends in arrears are not to be paid, any partial payment
     shall be made pro rata with respect to all Preferred Shares entitled to a
     dividend payment as of such Dividend Payment Date in proportion to the
     aggregate amounts remaining due in respect of such Preferred Shares as of
     such Dividend Payment Date. No interest or sum of money in lieu of interest
     shall be payable in respect of any dividend payment which may be in
     arrears.

          (iii) Method of Payment. Dividends on the Preferred Shares will be
     paid to the Depository which will credit such dividends to the accounts of
     the Agent Members of the beneficial owners as of the Business Day
     immediately preceding the Dividend Payment Date. Payments will be made in
     accordance with the Depository's normal procedures.

                                      A-18
<PAGE>   34

          (h) Limitations. So long as any of the Preferred Shares shall remain
     outstanding, the Fund shall not declare, pay or set aside for payment any
     dividend or other distribution in respect of any of the Common Shares or
     purchase or otherwise acquire for consideration any Common Shares, unless
     full cumulative dividends on all Preferred Shares for all past Dividend
     Periods ended on or prior to the date of such action shall have been
     declared and paid or sufficient funds set aside for the payment thereof.
     Owners of Preferred Shares shall not be entitled to any dividends in excess
     of full cumulative dividends as provided in this paragraph 3 except as the
     Board may declare in order to preserve the Fund's status as a regulated
     investment company under the Code.

          (i) Gross-up Payments Holders of the Preferred Shares 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 Agreement and
     Declaration and applicable law, dividends in an amount equal to the
     aggregate Gross-up Payments as follows:

               (i) Periods of 28 Days or Less. If, in the case of any period
          less than 28 days, the Fund allocates any net capital gains or other
          income taxable for Federal income tax purposes to a dividend paid on
          Preferred Shares (a "Taxable Allocation") without having given advance
          notice thereof to the Remarketing Agent, as provided below, 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
          Preferred Shares or the liquidation of the Fund, the Fund shall, prior
          to the end of the calendar year in which such dividend was paid,
          provide notice thereof to the Remarketing Agent and direct the Fund's
          dividend disbursing agent for the Preferred Shares 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 Fund.

               (ii) Periods Greater Than 28 Days. If, in the case of any period
          of more than 28 days, the Fund makes a Taxable Allocation to a
          dividend paid on Preferred Shares, the Fund shall, prior to the end of
          the calendar year in which such dividend was paid, provide notice
          thereof to the Remarketing Agent and direct the Fund's dividend
          disbursing agent for the Preferred Shares 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 Fund.

<PAGE>   35

               (iii) Internal Revenue Service Determination of Allocations The
          Fund shall not be required to make Gross-up Payments with respect to
          any net capital gains or other taxable income determined by the
          Internal Revenue Service to be allocable in a manner different from
          that allocated by the Fund.

               (iv) Notification of Allocations. Whenever the Fund intends to
          include any net capital gain or other income taxable for Federal
          income tax purposes in any dividend on Preferred Shares, the Fund
          shall, in the case of a period of 28 days or less, and may, in the
          case of any other period greater than 28 days, notify the Remarketing
          Agent of the amount to be so included not later than the Dividend
          Payment Date next preceding the last day of the Dividend Period on
          which the Dividend Rate for such dividend is to be established
          ("Allocation Notice Date"). Whenever the Remarketing Agent receives
          such notice from the Fund, it will be required in turn to notify each
          broker-dealer that is participating in the remarketing process
          pursuant to a Broker-Dealer Agreement, who, on or prior to such
          Allocation Notice Date, in accordance with its Broker-Dealer
          Agreement, will be required to notify its beneficial owners and
          potential beneficial owners of Preferred Shares believed by it to be
          interested in purchasing Preferred Shares in the remarketing process.

4. Redemption.

          (a) Optional Redemption. To the extent permitted under the 1940 Act
     and Massachusetts law, any Preferred Share of a series may be redeemed with
     funds available therefor, at the option of the Fund, upon notice mailed by
     first class mail to its Owner no more than 60 and no less than 10 days
     prior to the date fixed for redemption. Such redemption may be made on the
     day following the last day of any Dividend Period for that series, at a
     price of $5,000 per share, plus an amount equal to accumulated dividends,
     whether or not such dividends have been declared. (i) Subject to the
     provisions of subparagraph (iv) of this paragraph (a), to the extent
     permitted under the 1940 Act and Massachusetts law and upon notice mailed
     by first class mail to its Owners no more than 60 and no less than 10 days
     prior to the date fixed for redemption, Preferred Shares of any series may
     be redeemed, at the option of the Fund, 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 $5,000 plus an amount equal
     to accumulated but unpaid dividends thereon (whether or not earned or
     declared) to (but not including) the date fixed for redemption; PROVIDED,
     HOWEVER, that

                                      A-20
<PAGE>   36

     (1) shares of a series may not be redeemed in part if after such partial
     redemption fewer than 2500 shares of such series remain outstanding; and
     (2) unless otherwise provided herein, Preferred Shares of a series are
     redeemable by the Fund during the Dividend Period thereof only on the
     second Business Day next preceding the last Dividend Payment Date for such
     Dividend Period.

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

          (iii) Subject to the provisions of subparagraph (iv) of this paragraph
     (a), shares of any series of Preferred Shares may be redeemed, at the
     option of the Fund, as a whole but not in part, out of funds legally
     available therefor, on the first day following any Dividend Period thereof
     at a redemption price per share equal to the sum of $5,000 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.

          (iv) The Fund may not on any date mail a notice of redemption pursuant
     to paragraph (c)(i) of this paragraph 4 in respect of a redemption
     contemplated to be effected pursuant to this paragraph (a) unless on such
     date (a) the Fund has available deposit securities with maturity or tender
     dates not later than the day preceding the applicable redemption date and
     having a value not less than the amount (including any applicable premium)
     due to holders of Preferred Shared by reason of the redemption of such
     shares on such redemption date and (b) the Adjusted Value of Eligible
     Securities at least equal the Rating Agency Required Asset Coverage, and
     would at least equal the Rating Agency Required Asset Coverage immediately
     subsequent to such redemption if such redemption were to occur on such
     date.

          (b) Mandatory Redemption. If the Preferred Shares, Series A; Preferred
     Shares, Series B; Preferred Shares, Series C; Preferred Shares, Series D;
     and Preferred Shares, Series D are outstanding on the respective redemption
     dates set forth in paragraph 1 for each such series, then the Preferred
     Shares of such series shall be redeemed on such respective dates at a
     redemption price of $5,000 per share, in each case plus an amount equal to
     accumulated dividends, whether or not such dividends have been declared
     unless such date is extended for a series by vote of the Preferred Shares
     of such series. If the Rating Agency Required Asset Coverage is not

                                      A-21
<PAGE>   37

     met for eight consecutive Business Days or if the Fund fails to
     maintain the 1940 Act Asset Coverage and such failure is not cured in
     accordance with paragraph 6 on or before the 1940 Act Cure Date (each of
     such eighth consecutive Business Day and the 1940 Act Cure Date is herein
     referred to as a "Cure Date"), then the Fund shall (i) mail a notice of
     redemption to the Owners of the Preferred Shares and the Paying Agent on a
     date which is at least 10 days prior to the redemption date for the
     Preferred Shares, such redemption date being not later than the 30th day
     following such Cure Date (the "Mandatory Redemption Date"), and (ii) redeem
     on the Mandatory Redemption Date fixed in such notice, out of funds
     available therefor, at a redemption price equal to $5,000 per share, plus
     in each case an amount equal to accumulated dividends on such Preferred
     Shares (whether or not declared) to the Mandatory Redemption Date, the
     number of Preferred Shares equal to the lesser of (A) the minimum number of
     Preferred Shares the redemption of which, if deemed to have occurred
     immediately prior to the opening of business on such Cure Date would,
     together with all other preferred shares of beneficial interest of the Fund
     subject to redemption, have caused the Rating Agency Required Asset
     Coverage or 1940 Act Asset Coverage, as the case may be, to have been met
     on such Cure Date and (B) the maximum number of Preferred Shares, together
     with any other preferred shares of beneficial interest of the Fund subject
     to redemption, that can be redeemed out of funds expected to be available
     therefor on such Mandatory Redemption Date. In determining the number of
     Preferred Shares of a series required to be redeemed in accordance with
     this paragraph 4(b), the Fund shall allocate the number of Preferred Shares
     required to be redeemed in order to meet the Rating Agency Required Asset
     Coverage or 1940 Act Asset Coverage pro rata among each series of Preferred
     Shares. Funds for the redemption of the number of Preferred Shares required
     to be redeemed pursuant to this paragraph 4(b) shall be deposited with
     Paying Agent by noon, New York City Time, on the Business Day immediately
     following the Cure Date. If the Fund does not have funds available for the
     redemption on the Mandatory Redemption Date of all the Preferred Shares to
     be redeemed pursuant to paragraph 4(b)(ii)(A) or if the Fund is otherwise
     unable to effect such redemption on or prior to 30 days after such Cure
     Date, the Fund shall redeem those Preferred Shares which it was unable to
     redeem on the earliest practicable date next following the day on which the
     Fund shall first have funds available for the redemption of such Preferred
     Shares as shall be specified on like notice of redemption delivered to the
     Owners and the Paying Agent. Notwithstanding the fact that the Fund shall
     not have redeemed the full number of Preferred Shares required to restore
     the Rating Agency Required Asset Coverage or the 1940 Act
                                      A-22
<PAGE>   38

     Asset Coverage as contemplated above, dividends shall be declared and paid
     on the outstanding Preferred Shares.

          (c) Restrictions on Redemption of Preferred Shares. Notwithstanding
     the provisions of this paragraph 4, Preferred Shares may not be redeemed,
     other than in whole, unless, at the redemption date all accumulated
     dividends on the outstanding Preferred Shares for all Dividend Periods
     ending on or prior to such redemption date, shall have been or,
     contemporaneously are being paid, or sufficient funds for the payment
     thereof shall have been or, contemporaneously are being deposited with the
     Paying Agent.

          (d) Redemption Procedure. (i) Notice. Notice of redemption of
     Preferred Shares shall be addressed to the Owners thereof at their
     addresses appearing on the Stock Register and mailed within the time
     periods specified in paragraph 4(a) and 4(b) above by first class mail,
     postage prepaid. The Fund shall provide the Paying Agent with written
     notice of the redemption and the information contained in the notice of
     redemption at least one day prior to the date the notice of redemption is
     mailed to the Owners of the Preferred Shares. For purposes of the
     calculation of the date of redemption and the dates on which notices are
     given pursuant to this paragraph 4(d), a notice of redemption shall be
     deemed to be given on the day such notice is first so mailed. Each such
     notice shall set forth (A) the redemption date, (B) the number quantity,
     series designation and CUSIP number identity of the Preferred Shares to be
     redeemed, (C) the redemption price (specifying the amount of accumulated
     dividends to be included therein), (D) that dividends on the Preferred
     Shares to be redeemed will cease to accumulate on such redemption date, (E)
     the provision of this resolution under which redemption shall be made, and
     (F) the place or places where Owners may surrender their Preferred Shares
     and obtain payment of the redemption price. No defect in any notice of
     redemption or in the mailing thereof shall affect the validity of the
     redemption proceedings of Preferred Shares as to which no defect shall have
     occurred. In the event the Fund obtains appropriate exemptive or no-action
     relief from the staff of the Securities and Exchange Commission, the number
     of days notice required for a mandatory redemption may be reduced to such
     number of days as the Board of Trustees shall determine if Standard &
     Poor's and Moody's each has agreed or if both such Rating Agencies are not
     then rating the Preferred Shares, the one which has agreed, that the
     revised notice provision would not adversely affect its then current rating
     of the Preferred Shares.

          (ii) Selection of Preferred Shares. If fewer than all of the
     outstanding Preferred Shares are to be redeemed on any date, the Preferred
     Shares to be redeemed shall be selected by the Fund or its

                                      A-23
<PAGE>   39

     agents by lot or such other method as the Board shall determine to be fair
     and equitable, subject to paragraph (c)(ii) above and, in the case of a
     Mandatory Redemption, the requirement that Preferred Shares must be
     redeemed pro rata among all series. In the case of a redemption under
     paragraph 4(a) above, the Fund may apply the aforementioned procedures to
     one series of Preferred Shares rather than across the entire class of
     Preferred Shares.

          (iii) Deposit of Funds. Not later than 12:00 noon, New York City time,
     on the date on which notice is given pursuant to paragraph 4(a) above (or
     an such date as may be required pursuant to mandatory redemption as set
     forth in paragraph 4(b) above), the Fund shall deposit with the Paying
     Agent funds sufficient to redeem the Preferred Shares to be redeemed on
     such date and shall give to the Paying Agent irrevocable instructions and
     authority to apply such funds and the proceeds therefrom to the payment of
     the redemption price, plus accumulated dividends, whether or not earned or
     declared, upon surrender of such Preferred Shares. Not later than 12:00
     noon, New York City time, on the 30th day prior to the date on which the
     Preferred Shares of a series are scheduled for redemption under paragraph 1
     the Fund shall deposit with the Paying Agent (i) cash or (ii) municipal
     securities which are rated at least "A-1+" by Standard & Poor's and which
     mature on or before the date such Preferred Shares are to be redeemed in an
     amount which is sufficient to redeem the Preferred Shares to be redeemed on
     such date and shall give the Paying Agent irrevocable instructions and
     authority to apply such funds and the proceeds therefrom to the payment of
     the redemption price, plus accumulated dividends, whether or not declared,
     upon surrender of such Preferred Shares. Upon the failure of the Fund to
     deposit such funds cash or securities, the Fund will immediately liquidate
     portfolio securities in an amount which will enable it to make such
     deposits and will deposit the proceeds of such sales in accordance with
     this paragraph. Neither the Preferred Shares to be redeemed nor the funds
     so deposited with the Paying Agent shall be included in or reflected in any
     calculation of Rating Agency Required Asset Coverage as of an Evaluation
     Valuation Date occurring on or subsequent to the date of such deposit.

          (iv) Effect of Deposit. If notice of redemption shall have been given,
     upon the irrevocable deposit of funds sufficient to effect such redemption,
     all rights of the Owners of the Preferred Shares so called for redemption
     shall cease, except the right of such Owners to receive the redemption
     price, plus accumulated dividends, whether or not earned or declared, but
     without interest, and such Preferred Shares shall no longer be deemed to be
     outstanding for

                                      A-24
<PAGE>   40

     any purpose. The Fund shall be entitled to receive, from time to time from
     the Paying Agent the interest, if any, earned on such funds deposited with
     the Paying Agent; and the Owners of the Preferred Shares so redeemed shall
     have no claim to any such interest. Any funds so deposited which shall be
     unclaimed at the end of one year from such redemption date shall be paid by
     the Paying Agent to the Fund upon its request. Thereupon, the Paying Agent
     shall be relieved of all responsibility to the Owners of such Preferred
     Shares; and such Owners shall look only to the Fund for payment.

          (e) Purchase of the Preferred Shares. Nothing contained in this
     resolution shall limit any ability which the Fund may otherwise have to
     purchase or otherwise acquire any Preferred Shares at any price so long as,
     at the time of any such purchase, there is no arrearage in the payment of
     dividends on any Preferred Shares and the Rating Agency Required Asset
     Coverage and 1940 Act Asset Coverage are met, after giving effect to such
     purchase or acquisition, on the date thereof. Not later than the close of
     business on the date of such acquisition, the Fund shall deliver to the
     Paying Agent a Certificate of Rating Agency Required Asset Coverage
     demonstrating compliance with this paragraph 4(e), with the mathematical
     accuracy of any calculations set forth in such Certificate of Rating Agency
     Required Asset Coverage confirmed in writing by the Fund's independent
     certified public accountants.

          (f) Status of Redeemed or Purchased Preferred Shares. Any Preferred
     Shares at any time purchased, redeemed or otherwise acquired by the Fund
     shall become treasury shares and may be reissued by the Fund.

5. Voting Rights.

          (a) General. (i) In addition to any voting rights granted to the
     Preferred Shares pursuant to the 1940 Act, Owners of the Preferred Shares
     shall be entitled to one vote for each Preferred Share held on each matter
     submitted to a vote of shareholders of the Fund and, except as otherwise
     provided in the Agreement and Declaration or by law, the holders of
     Preferred Shares, including any other preferred shares of beneficial
     interest of the Fund, and of Common Shares shall vote together as a single
     class; provided that (A)(i) at any meeting of the shareholders of the Fund
     held for the election of trustees the holders of a plurality of the
     outstanding Preferred Shares and any other preferred shares of beneficial
     interest of the Fund, 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 beneficial interests of the Fund, to elect two
     trustees of the Fund, each Preferred Share and any other preferred

                                      A-25
<PAGE>   41

     shares of beneficial interest of the Fund entitling the holder thereof to
     one vote (ii) at any meeting of the shareholders of the Fund held for the
     extension of the stated mandatory redemption date for Preferred Shares,
     Series A; Preferred Shares, Series B; Preferred Shares, Series C; Preferred
     Shares, Series D or Preferred Shares, Series E, the holders of Preferred
     Shares of the series affected by such extension, represented in person or
     by proxy at said meeting, shall be entitled as a class, to the exclusion of
     the holders of all other Preferred Shares and other shares of beneficial
     interest of the Fund, to extend the stated mandatory redemption date for
     such series to a later date, each Preferred Share of such series entitling
     the holder thereof to one vote, (B)(ii) at any meeting of the shareholders
     of the Fund held for the purpose of increasing or decreasing the number of
     Preferred Shares of a previously designated series authorized to be issued,
     the holders of Preferred Shares of the series affected by such increase or
     decrease, represented in person or by proxy at such meeting, shall be
     entitled as a class, to the exclusion of the holders of all other Preferred
     Shares and other shares of beneficial interest of the Fund, to vote with
     respect to such increase or decrease, each Preferred Share of such series
     entitling the holder thereof to one vote, (C)(iii) at any meeting of the
     shareholders of the Fund held to amend, alter or repeal any of the
     preferences, rights or powers of the Preferred Shares, or any series
     thereof or increase or decrease the number of Preferred Shares authorized
     to be issued, the holders of the Preferred Shares, or series of shares, as
     the case may be, represented in person or by proxy at said meeting shall be
     entitled as a class, to the exclusion of the holders of all other shares of
     beneficial interest of the Fund, to vote on such preferences, rights or
     powers or increase or decrease in the number of the Preferred Shares or
     series thereof authorized to be issued, and (D)(iv) at any meeting of the
     shareholders of the Fund held to approve any plan of reorganization
     affecting the Preferred Shares or any action requiring a vote of security
     holders under Section 13(a) of the 1940 Act, the holders of the Preferred
     Shares and any other preferred shares of beneficial interest of the Fund
     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 beneficial interest of the Fund to vote on such plan of reorganization
     or action requiring a vote of security holders under Section 13(a) of the
     1940 Act, and (E) except as otherwise provided in the Agreement and
     Declaration or by law, the holders of Preferred Shares of each individual
     series, as a separate series, shall vote, to the exclusion of the holders
     of all other series of Preferred Shares, as a single class on those matters
     that materially affect that series in a manner different from that of other
     series or classes of the Fund's shares. Nothing in this section shall be
     interpreted to restrict the ability of the Trustees, without
                                      A-26
<PAGE>   42

     shareholder approval, to establish and designate additional series of
     preferred shares, consistent with the terms of the Agreement and
     Declaration and applicable law provided however, that for so long as any
     Preferred Shares are outstanding and Moody's or Standard & Poor's, or both,
     are rating such shares, the Fund will not issue any additional shares of
     any class or series of preferred shares ranking on a parity with the
     Preferred Shares with respect to the payments of dividends and the
     distribution of assets upon dissolution, liquidation or winding up of the
     affairs of the Fund, unless it has received written confirmation from
     Moody's or Standard & Poor's, or both, as appropriate, that any such action
     would not impair the ratings then assigned by such rating agency to the
     Preferred Shares. If Moody's or Standard & Poor's is not then rating the
     Preferred Shares, the Fund will not issue any additional shares of any
     class or series of preferred shares ranking on a parity with the Preferred
     Shares with respect to the payment of dividends and the distribution of
     assets upon dissolution, liquidation or winding up of the affairs of the
     Fund, if the aggregate liquidation preference of all Preferred Shares of
     the Fund outstanding after any such issuance, exclusive of accumulated and
     unpaid dividends, exceeds [$                ]. Subject to paragraph 5(b)
     hereof, the holders of a plurality of the outstanding Common Shares and
     Preferred Shares and any other preferred shares of beneficial interest of
     the Fund, voting together as a single class, shall elect the balance of the
     trustees.

          (ii) So long as any shares of Municipal Preferred are outstanding, the
     Fund may not, without the affirmative vote of the holders of at least
     66 2/3% of the shares of Municipal Preferred outstanding at the time, in
     person or by proxy, in writing or at a meeting, voting as a separate class,
     file a voluntary application for relief under Federal bankruptcy law or any
     similar application under state law for so long as the Fund is solvent and
     does not foresee becoming insolvent.

          (b) Right to Elect Majority of Board of Trustees. During any period in
     which any one or more of the conditions described below shall exist (such
     period being referred to herein as a "Voting Period"), the number of
     trustees constituting the Board shall be automatically increased by the
     smallest number that, when added to the two trustees elected exclusively by
     the holders of Preferred Shares and any other preferred shares of
     beneficial interest of the Fund, would constitute a majority of the Board
     as so increased by such smallest number; and the holders of Preferred
     Shares and any other preferred shares of beneficial interest of the Fund,
     shall be entitled, voting as a class on a one-vote-per-share basis (to the
     exclusion of

                                      A-27
<PAGE>   43

     the holders of all other securities and classes of beneficial interest of
     the Fund), to elect such additional trustees, together with the two
     trustees that such holders are in any event entitled to elect. A Voting
     Period shall commence:

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

               (ii) if at any time holders of any other preferred shares of
          beneficial interest of the Fund are entitled to elect a majority of
          the trustees of the Trust.

               Upon the termination of a Voting Period, which, in the case of
          paragraph 5(b)(i), shall be the date on which all dividends in arrears
          shall have been paid or deposited with the Paying Agent the voting
          rights described in this paragraph 5(b) shall cease subject always,
          however, to the revesting of such voting rights in the Owners upon the
          further occurrence of any of the events described in this paragraph
          5(b).

          (c) Voting Procedures. (i) As soon as practicable after the accrual of
     any right of the Owners of Preferred Shares to elect additional trustees as
     described in paragraph 5(b) above, the Fund shall notify the Paying Agent
     and the Paying Agent shall distribute the call of a special meeting of the
     Owners, by mailing a notice of such special meeting to such Owners; such
     meeting to be held not less than 10 nor more than 20 days after the date of
     mailing of such notice. If the Fund fails to send such notice to the Paying
     Agent or if the Paying Agent does not distribute such call of the special
     meeting, it may be called by the Owners of 25% of the Preferred Shares and
     any other preferred shares of beneficial interest of the Fund entitled to
     vote on the matter on like notice. The record date for determining the
     Owners entitled to notice of and to vote at such special meeting shall be
     the close of business on the fifth Business Day preceding the day on which
     such notice is mailed. At any such special meeting and at each meeting held
     during a Voting Period, such Owners and the holders of any other preferred

     the exclusion of the holders of all other securities and classes of
     beneficial interests of the Fund), shall be entitled to elect the number of
     trustees prescribed in paragraph 5(b) above on a one-vote-per-share

     quorum, a majority of such Owners and the holders of any other preferred
     shares of beneficial interest of the Fund, present in person or any proxy
     shall have the power to adjourn the meeting without notices, other than an
     announcement at the meeting, until a quorum is present.

          (ii) For purposes of determining any rights of the Owners to vote on
     any matter, whether such right is created by this resolution, by any other
     provisions of the Agreement and Declaration, by the 1940 Act or another
     statute or otherwise, no Owner shall be entitled to vote and no Preferred
     Share shall be deemed to be "outstanding" for the purpose of voting or
     determining the number of Preferred Shares required to constitute a quorum
     if, prior to or concurrently with the time of determination of Preferred
     Shares entitled to vote or Preferred Shares deemed outstanding for quorum
     purposes, as the case may be sufficient funds for the redemption of such
     Preferred Shares have been deposited in trust with the Paying Agent for
     that purpose and the requisite notice of redemption with respect to such
     Preferred Shares shall have been given as provided in paragraph 4(d)(i). No
     Preferred Share held by the Fund shall have any voting rights or be deemed

     holders of the number of trustees that they are entitled to elect, and the
     persons so elected by such Owners and such other holders, together with the
     two incumbent trustees elected by the Owners and such other holders of
     preferred shares of beneficial interest of the Fund and the remaining
     incumbent trustees elected by the holders of the Common Shares and the
     Preferred Shares and other preferred shares of beneficial interest of the
     Trust, shall constitute the duly elected trustees of the Trust.

          (iv) Simultaneously with the expiration of a Voting Period, the terms
     of office of the additional trustees elected by the Owners and holders of
     other preferred shares of beneficial interest of the Fund pursuant to
     paragraph 5(b) above shall terminate, the remaining trustees shall
     constitute the trustees of the Fund and the voting rights of the Owners and
     such other holders to elect additional trustees pursuant to paragraph 5(b)
     above shall cease.

          (d) Exclusive Remedy. Unless otherwise required by law, the Owners
     shall not have any relative rights or preferences or other

                                      A-29
<PAGE>   45

     special rights other than those specifically set forth herein. The Owners
     of Preferred Shares shall have no preemptive rights or rights to cumulative
     voting. In the event that the Fund fails to pay any dividends on the
     Preferred Shares, the exclusive remedy of the Owners shall be the right to
     vote for trustees pursuant to the provisions of this paragraph 5. In no
     event shall the Owners have any right to sue for, or bring a proceeding
     with respect to, such dividends or redemptions or damages for the failure
     to receive the same.

6. Asset Coverage and Dividend Coverage.

          (a) The Fund shall maintain, as of the last Business Day of each month
     in which any Preferred Share is outstanding, assets at least equal to the
     1940 Act Asset Coverage.

          (b) To meet the Rating Agency Required Asset Coverage tThe Fund shall
     maintain Rating Agency Required Assets assets with a Value (as calculated
     under paragraph 7(c)) equal to the Rating Agency Required Asset Coverage.
     that is sufficient to cover the aggregate liquidation preference of the
     outstanding Preferred Shares ("Rating Agency Required Assets"). The Rating
     Agency Required Asset Coverage must be calculated and met on each
     Evaluation Valuation Date. It will be met if the Fund owns Rating Agency
     Required Assets with a Rating Agency Value equal to or greater than the
     product of (i) the total number of Preferred Shares then outstanding and
     (ii) $5,000.

          (c) On each Evaluation Valuation Date, the Fund shall calculate and
     determine pursuant to the procedures set forth herein: (i) the Market Value
     of each Rating Agency Required Asset owned by the Fund on that date, (ii)
     the Adjusted Value of each such Rating Agency Required Asset, (iii) the
     aggregate Adjusted Value of all such Rating Agency Required Assets, (iv)
     the Value of all such Rating Agency Required Assets, and (v) whether the
     Rating Agency Required Asset Coverage is met as of that date, (vi) the
     Rating Agency Dividend Coverage Assets owned by the Fund on that date,
     (vii) the Rating Agency Dividend Coverage amount on that date, and (viii)
     whether the Rating Agency Dividend Coverage is met as of that date,. Each
     such calculation shall be set forth in a certificate (the "Certificate of
     Rating Agency Required Asset Coverage"), which must be delivered to the
     Paying Agent not later than the close of business an the fifth Business Day
     following the Date of Original Issue and not later than the close of
     business on the third Business Day following (i)(A) any Evaluation
     Valuation Date on which the Rating Agency Required Asset Coverage or Rating
     Agency Dividend Coverage is not met, (ii)(B) any time the Fund's Standard &
     Poor's Adjusted Value fails to exceed the Rating Agency Required

                                      A-30
<PAGE>   46

     Asset Coverage by 5% or more, (iii)(C) the first Evaluation Valuation Date
     succeeding any Evaluation Valuation Date referred to in clause (i)(A) above
     on which the Rating Agency Required Asset Coverage and Rating Agency
     Dividend Coverage are is met, and (iii)(D) the last Evaluation Valuation
     Date of each month, (E) any redemption by the Fund of its Common Shares,
     and (F) any request by Standard & Poor's. So long as Standard & Poor's or
     Moody's is rating the Preferred Shares, a Certificate of Rating Agency
     Required Asset Coverage shall be delivered to Standard & Poor's (if
     Standard & Poor's is rating the Preferred Shares) and Moody's (if Moody's
     is rating the Preferred Shares) not later than the close of business on the
     fifth Business Day following the Date of Original Issue and the third
     Business Day following an Evaluation Valuation Date specified in (A) (i) or
     (B) (ii) above. Failure to deliver a Certificate of Rating Agency Required
     Asset Coverage shall be deemed to be delivery of a Certificate of Rating
     Agency Required Asset Coverage indicating that the Fund does not own assets
     with a Value equal to the Rating Agency Required Asset Coverage.

          The definitions of and methods of calculation of "Market Value,"
     "Adjusted Value," "Value", "Rating Agency Required Assets", and "Rating
     Agency Required Asset Coverage," "Rating Agency Dividend Coverage Assets"
     and "Rating Agency Dividend Coverage" may be changed from time to time by
     the Fund without shareholder approval, but only in the event the Fund
     receives written confirmation from Standard & Poor's and Moody's, or if
     both such Rating Agencies are not then rating the Preferred Shares, the one
     which is, that any such change would not impair the ratings then assigned
     to the Preferred Shares. To the extent these definitions and methods of
     calculation are changed by Moody's or Standard & Poor's in a manner that
     would impair the ratings then assigned to the Preferred Shares if the Fund
     failed to take action to meet such revised definitions and methods of
     calculation, the Fund will take such action as is necessary to comply with
     such revised definitions and methods of calculation so as to maintain the
     then current rating on the Preferred Shares or will redeem the then
     outstanding Preferred Shares.

          (d) In connection with the Certificates of Rating Agency Required
     Asset Coverage to be given with respect to (A) the Date of Original Issue,
     and(B) the last Evaluation Valuation Date of each fiscal quarter of the
     Fund, and (C) a randomly selected date within each fiscal quarter, the
     Fund's independent public accountants will deliver to the Paying Agent and
     to Standard & Poor's (if Standard & Poor's is rating the Preferred Shares)
     and Moody's (if Moody's is rating the Preferred Shares) a written
     communication

     ("Ratings Agency Accountant's Confirmation") confirming (i) the
     mathematical accuracy of the calculations reflected in such Certificate,
     (ii) that the method used by the Fund in determining whether or not the
     Rating Agency Required Asset Coverage and Rating Agency Dividend Coverage
     were was met is in accordance with the applicable requirements of the
     Certificate of Designation for Preferred Shares, (iii) that the price
     quotations used by the Fund in such determination conform to the written
     price quotations obtained by the Fund from the pricing services utilized by
     the Fund, and (iv) that the assets listed as Rating Agency Required Assets

     Accountants' Confirmation to be delivered to the Paying Agent by the close
     of business on the fifth tenth Business Day following the Date of Original
     Issue and by the close of business on the fifth tenth Business Day
     following each such Evaluation Valuation Date of each fiscal quarter of the
     Fund. If any Rating Agency Accountants' Confirmation differs from the
     Fund's Certificate of Rating Agency Required Asset Coverage, the Rating
     Agency Accountants' Confirmation will control and the Fund will notify
     Standard & Poor's (if Standard & Poor's is rating the Preferred Shares) and
     Moody's (if Moody's is rating the Preferred Shares) of such difference.

          (e) If the Rating Agency Required Asset Coverage is not met as
     required, the Fund may (i) purchase or otherwise acquire additional Rating
     Agency Required Assets , (ii) sell all or a portion of its Rating Agency
     Required Assets at a price which is higher than the Adjusted Value of such
     Rating Agency Required Assets, (iii) liquidate all or a portion of its
     municipal securities options or financial futures contracts or related
     options contracts, if any, or (iv) purchase Preferred Shares, or effect any
     combination of these transactions, so that the Rating Agency Required Asset
     Coverage will be met.

          (f) In addition, for so long as Standard & Poor's is rating the
     Preferred Shares, the Rating Agency Dividend Coverage must be met as of
     each Evaluation Date and will be met if the Fund owns Rating Agency
     Dividend Coverage Assets with an aggregate Adjusted Value equal to or
     greater than the full amount of dividends on the Preferred Shares which
     will be due and payable on the next succeeding Dividend Payment Date. If
     the Rating Agency Dividend Coverage is not met as of an Evaluation Date,
     the Fund may

     financial futures contracts or related options contracts, if any, or (iii)
     otherwise acquire Rating Agency Dividend Coverage Assets, or effect any
     combination of these transactions, so that the Rating Agency Dividend
     Coverage will be met.

          (f) (g) If a Rating Agency Accountants' Confirmation has been
     delivered to the Paying Agent with respect to an Evaluation Valuation Date
     on which the Rating Agency Required Asset Coverage or Rating Agency
     Dividend Coverage was not met, the Fund shall cause a Rating Agency
     Accountants' Confirmation, in respect of the next Evaluation Valuation Date
     on which the Rating Agency Required Asset Coverage and the Rating Agency
     Dividend Coverage are is met, to be delivered to the Paying Agent by the
     fifth Business Day following such next Evaluation Valuation Date.

          (g) The Fund may use cash or proceeds generated from sales of assets

7. Calculations of Coverage.

          (a) Calculation I. (i) The Market Value of eEach Eligible Municipal
     Security's Market Value shall be calculated on each Valuation Date. shall
     be computed by using market quotations, or independent pricing services
     that use prices provided by market makers or estimates of market values
     obtained from yield data relating to instruments or securities with similar
     characteristics; (ii) The Market Value of each Rating Agency Required Asset
     other than Eligible Municipal Securities shall be computed as follows:

               (A) cash shall be valued at face amount;

               (B) demand and time deposits, next-day federal funds and next-day
          repurchase agreements shall be valued at face amount plus accrued
          interest, if any, to the date of valuation; and

               (C) the aggregate outstanding principal balances of the mortgage
          loans evidenced by each FNMA, FHLMC and GNMA Certificate and each
          Qualifying Mortgage Pass-Through Certificate (as shown on the most
          recent report related to such certificates received by the Fund prior
          to the applicable date of valuation) and the principal amount of each
          CMO, Securitized Receivable, Short-Term Money Market Instrument
          (except for those described in clause (b) above), Certificate of
          Deposit and U.S. Treasury Security will be multiplied by the lower of
          the bid prices, as of the close of business on the Business Day next
          preceding the applicable date of valuation,

                                      A-33
<PAGE>   49

          as quoted in writing to the Fund by two nationally recognized
          securities dealers selected by the Fund and making a market in such
          securities at the time (provided that (1) if only one of such bid
          prices is available, except in the case of Qualifying Mortgage
          Pass-Through Certificates and CMOs, then the calculation shall be
          based both on the one such bid price that is available and the price
          for the Business Day next preceding the applicable date of valuation
          published in either The Wall Street Journal or The New York Times,
          provided that Moody's, if Moody's is then rating the Preferred Shares,
          shall have advised the Fund in writing that its then-current rating of
          the Preferred Shares would not be affected if the calculation were
          based on such price published in either The Wall Street Journal or The
          New York Times or (2) if no such bid price is available or in the case
          of Qualifying Mortgage Pass-Through Certificates and CMOs, then the
          calculations shall be based upon such price or prices as are obtained
          from alternative sources as the Fund in good faith deems to be
          reliable, provided that each of Moody's and Standard & Poor's or, if
          both such Rating Agencies are not then rating the Preferred Shares the
          one which is, shall have advised the Fund in writing that its
          then-current rating of the Preferred Shares would not be adversely
          affected if the calculation were based on such price or prices
          obtained from such alternative sources), and accrued interest, if any,
          on such security shall be added thereto; and

               (C) the Market Value of any Other Securities constituting Rating
          Agency Required Assets shall be calculated on each Valuation Date.
          (D)if Other Securities become includible in Rating Agency Required
          Assets, the calculation of Market Value of such Other Securities shall
          be determined in accordance with such procedures as shall be
          established by the Board of Trustees (and set forth in a certificate
          signed by an officer of the Fund, filed with the records of the Fund
          and available for inspection by the shareholders of the Fund),
          provided that each of Moody's and Standard & Poor's, or, if both such
          rating services are not then rating the Preferred Shares, the one
          which is, shall have advised the Fund in writing that its then-current
          rating of the Preferred Shares would not be adversely affected if such
          procedures were established by the Board of Trustees.

     The calculation of Market Value may be made on bases other than those set
     forth herein above determined in accordance with procedures established by
     the Board of Trustees (and set forth in a certificate signed by an officer
     of the Fund, filed with the records of the

                                      A-34
<PAGE>   50

     Fund and available for inspection by the shareholders of the Fund) if
     Moody's and Standard & Poor's have advised or, if both of such Rating
     Agencies are not then rating the Preferred Shares, the one which is, has
     advised the Fund in writing that the alternative calculation of Market
     Value would not, or that a failure to use the alternative calculation
     would, adversely affect their respective then-current ratings of the
     Preferred Shares.

          (b) Calculation II. The Adjusted Value of Eligible Municipal
     Securities shall be the lesser of the Standard & Poor's Adjusted Value and
     the Moody's Adjusted Value, determined as follows.

               (i) Standard & Poor's "AAA" Rating Guidelines ("Standard & Poor's
          Adjusted Value"). The Standard & Poor's Adjusted Value of a Standard
          and Poor's Eligible Security (a each municipal security eligible for
          consideration under Standard & Poor's guidelines in effect as of the
          date of this Certificate of Designation), for Preferred Shares
          ("Standard & Poor's Eligible Municipal Securities") shall be the
          Market Value of such Standard & Poor's Eligible Municipal Security
          divided by 155% for an "AAA" rated Standard & Poor's Eligible
          Municipal Security, or for an Escrowed Bond that has been determined
          to be legally or economically defeased in accordance with Standard &
          Poor's defeasance criteria and is considered to be a Standard & Poor's
          Eligible Security, 160% for an "AA" rated Standard & Poor's Eligible
          Municipal Security, 175% for an "A" rated Standard & Poor's Eligible
          Municipal Security, and 215% for a "BBB" rated Standard & Poor's
          Eligible Municipal Security and 220% for an unrated Standard & Poor's
          Eligible Security ("Standard & Poor's Municipal Security Discount
          Factors").

               Notwithstanding the foregoing, the Standard & Poor's Municipal
          Security Discount Factor for short-term Standard & Poor's Eligible
          Municipal Securities shall be 115%, so long as such Standard & Poor's
          Eligible Municipal Securities are rated "A-l+" or "SP-l+" by Standard
          & Poor's and mature or have a demand feature exercisable in 30 days or
          less, or 120% so long as such Standard & Poor's Eligible Securities
          are rated "A-1" or "SP-1" by Standard Poor's and mature or have a
          demand feature exercisable in 30 days or less, or 125% if such
          Standard & Poor's Municipal Securities are not rated by Standard &
          Poor's but are rated "VMIG-l", "P-1" or "MIG-1" by Moody's; provided,
          however, that if such Standard & Poor's Eligible Municipal Securities
          are backed by any letter of credit, liquidity facility or guarantee
          from a bank or other financial institution, such bank or institution
          must have a short-term

                                      A-35

          rating of at least "A-l+" from Standard & Poor's; and further provided
          that such Moody's-rated short-term Standard & Poor's Eligible
          Municipal Securities may comprise no more than 50% of short-term

          at least "A" by an NRSRO Moody's; provided that such NRSRO
          Moody's-rated municipal securities will be included in Standard &
          Poor's Eligible Municipal Securities only to the extent the fair
          market value of such municipal securities does not, when aggregated
          with any unrated securities, not exceed 50% of the aggregate fair
          market value of all Standard & Poor's Eligible Municipal Securities.
          For purposes of determining the Standard & Poor's Municipal Security
          Discount Factors applicable to such NRSRO Moody's-rated municipal
          securities, any such municipal security will be deemed to have a
          Standard & Poor's rating which is one full rating category lower than
          its NRSRO Moody's rating;

               (4) Not have been issued in a private placement (excluding

     municipal securities exceed 5% of the aggregate Market Value of the
     Standard & Poor's Eligible Municipal Securities (excluding short-term
     Standard & Poor's Eligible Municipal Securities). In the case of securities
     not so rated, any one issuer or guarantor (excluding bond insurers) shall
     be considered Standard & Poor's Eligible Securities only to the extent the

          of each municipal security eligible for consideration under Moody's
          guidelines in effect as of the date of this Certificate of Designation
          for Preferred Shares ("Moody's Eligible Municipal Securityies") shall
          be the Market Value of such Moody's Eligible Municipal Security
          divided by 151% for an "Aaa" rated Moody's Eligible Municipal
          Security, 159% for an "Aa" rated Moody's Eligible Municipal Security,
          168% for an "A" rated Moody's Eligible Municipal Security, 173% for a
          "Baa" rated Moody's Eligible Municipal Security, and 187%

          for a municipal security not rated by Moody's but rated "BBB-
          " by Standard & Poor's, and 225% for a municipal security not rated by
          Moody's or by Standard & Poor's (Moody's Municipal Security Discount
          Factors").

               Notwithstanding the foregoing, the Moody's Municipal Security
          Discount Factor for short-term Moody's Eligible Municipal Securities
          shall be 115%, so long as such Moody's Eligible Municipal Securities
          are rated at least "MIG-1", "VMIG-1" or "P-1" by Moody's or "A-1+/AA"
          or "SP-1/AA" by Standard & Poor's and mature or have a demand feature
          at par exercisable in 30 days or less.

               The following limitations shall determine the maximum portion of
          the Fund's Eligible Municipal Securities which may be Moody's Eligible
          Municipal Securities:

            by Standard & Poor's.

               Municipal Securities constituting Moody's Eligible Municipal
          Securities shall pay interest in cash, shall be publicly rated "Baa"
          or higher by Moody's or, if not rated by Moody's but rated by Standard

          Moody's Security Discount Factors applicable to such Standard & Poor's
          rated Moody's Eligible Municipal Securities, any such municipal
          security (excluding short-term municipal securities) shall be deemed
          to have a Moody's rating which is one full rating category lower than
          its Standard & Poor's rating.

          Required Assets is the aggregate Adjusted Value of the Rating Agency
          Required Assets.

               In accordance with procedures established by the Board (and set
          forth in a certificate signed by an officer of the Fund,

                                      A-40
<PAGE>   56

          filed with the records of the Fund and available for inspection
          by the shareholders of the Fund), the discount factor applied to
          determine the Adjusted Value of any Rating Agency Required Asset may
          be changed from that set forth above if Moody's and Standard & Poor's
          have advised or, if both of such Rating Agencies are not then rating
          the Preferred Shares, the one which is rating the Preferred Shares has
          advised the Fund in writing that the revised discount factor would
          not, or that a failure to use the revised discount factor would,
          adversely affect their respective then-current ratings of the
          Preferred Shares. If Other Securities become includible in Rating
          Agency Required Assets, the calculation of the Adjusted Value of such
          Other Securities will be determined in accordance with procedures as
          are established by the Board of Trustees (and set forth in a
          certificate signed by an officer of the Fund, filed with the records
          of the Fund and available for inspection by the shareholders of the
          Fund) and as are acceptable to Moody's and Standard & Poor's if the
          Preferred Shares are then rated by both such Rating Agencies, or, if
          not rated by both, to the one, if any, such Rating Agency then rating
          the Preferred Shares.

          (c) Calculation III. For the purpose of determining whether the Rating
     Agency Required Asset Coverage is met in accordance with paragraph 6(b),
     the Value of the Rating Agency Required Assets shall be calculated by (i)
     reducing the aggregate Adjusted Value of the Rating Agency Required Assets
     by (A) the amount of all known liabilities (including, without limitation,
     indebtedness, operating expenses payable and securities sold under
     agreements to repurchase) which appear on the applicable Evaluation
     Valuation Date on the Fund's balance sheet and the amount of operating
     expenses projected by the Fund to be incurred by the Fund during the
     succeeding three months, (B) so long as the Preferred Shares are rated by
     Standard & Poor's, the amount described in paragraph 7(d) below, and (C) an
     aggregate amount for all Preferred Shares calculated for each series of the
     Preferred Shares, as of the Evaluation Valuation Date, as follows: the
     amount of accumulated but unpaid dividends on such series (unless set aside
     with the Paying Agent for payment) to the Evaluation Valuation Date plus
     dividends projected to accumulate on such series from and including the
     Evaluation Valuation Date to but excluding the first day of the next
     Dividend Period for such series at the Dividend Rate for such series in
     effect for such series on the Evaluation Valuation Date plus the amount of
     dividends which would accumulate on the shares of such series from and
     including the first day of the next Dividend Period for such series through
     the [497th] day following the Evaluation Valuation Date at the Dividend
     Rate in effect for such series on such

                                      A-41
<PAGE>   57

     Evaluation Valuation Date for such series multiplied by the Volatility
     Factor [2.28], and (D) the amount of any Gross-up Payment in respect
     of any Preferred Shares as of such Valuation Date, and (ii) increasing the
     aggregate Adjusted Value of Rating Agency Required Assets by (A) the amount
     of receivables for portfolio securities sold as of the Evaluation Valuation
     Date, (B) the amount of any interest receivable on portfolio securities as
     of the Evaluation Valuation Date and (C) the value of any Fund assets
     irrevocably deposited by the Fund for the payment of any of (i)(A) through
     (i)(C) above.

          (d) Hedging Transactions. (i) For so long as any shares of Preferred
     Shares are rated by Standard & Poor's, the Fund will not 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 unless it receives written
     confirmation from Standard & Poor's that engaging in such transactions will
     not impair the ratings then assigned to the Preferred Shares by Standard &
     Poor's, except that the Fund 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, "Standard &
     Poor's Hedging Transactions"), subject to the following limitations.

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

               (B) the Fund will not engage in any Standard & Poor's Hedging
          Transaction based on Treasury Bonds (other than Closing Transactions)
          which would cause the Fund at the time of such transaction to own or
          have sold the lesser of (i) outstanding futures contracts based on
          Treasury Bonds exceeding in number 50% of the quotient of the Market
          Value of

                                      A-42
<PAGE>   58

          the Fund's total assets divided by $100,000 ($200,000 in the
          case of the two-year United States Treasury Note) or (ii) 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;

               (C) the Fund will engage in Closing Transactions to close out any
          outstanding futures contract which the Fund owns or has sold or any
          outstanding option thereon owned by the Fund in the event (i) the Fund
          does not have Standard & Poor's Eligible Assets with an aggregate
          Discounted Value equal to or grater than the Rating Agency Required
          Asset Coverage on two consecutive Valuation Dates and (ii) the Fund is
          required to pay additional margin due to fluctuation in contract price
          ("Variation Margin") on the second such Valuation Date;

               (D) the Fund 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 Fund holds the securities deliverable under
          such terms; and

               (E) when the Fund 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 Standard & Poor's), fixed-income securities in
          a segregated account with the Fund's custodian, so that the amount so
          segregated plus the amount of margin paid on such contract ("Initial
          Margin") and any Variation Margin held in the amount of or on behalf
          of the Fund'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 Fund 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 Fund has Standard & Poor's Eligible
Securities with a Discounted Value that equals or exceeds the Rating Agency
Required Asset Coverage, 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 Standard & Poor's Eligible Assets 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 Fund plus (ii) 25% of the aggregate settlement value, as marked to

                                      A-43
<PAGE>   59

market, of any outstanding futures contract based on Treasury Bonds which
contracts are owned by the Fund.

          (ii) For as long as any Preferred Shares are rated by Moody's, the
     Fund will not buy or sell futures contracts, write, purchase or sell call
     options on futures contracts or purchase put options on futures contracts
     or write call options (except covered call options) on portfolio securities
     unless it receives written confirmation from Moody's that engaging in such
     transactions would not impair the ratings then assigned to the shares of
     Preferred Shares by Moody's, except that the Fund may purchase or sell
     exchange-traded futures contracts based on the Municipal Index or Treasury
     Bonds and purchase, write or sell exchange-traded put options on such
     futures contracts and purchase, write or sell exchange-traded call options
     on such futures contracts (collectively, "Moody's Hedging Transactions"),
     subject to the following limitations:

               (A) the Fund will not engage in any Moody's Hedging Transaction
          based on the Municipal Index (other than Closing Transactions) which
          would cause the Municipal Bonds rated by Moody's but not rated by
          Standard & Poor's may comprise no more than 50% of short-term
          municipal securities that qualify as Standard & Poor's Eligible
          Securities;

               (B) the Standard & Poor's Security Discount Factor for funds to
          be received for sales of municipal securities that are due in more
          than five Business days from such Valuation Date will be the Standard
          & Poor's Security Discount Factor applicable to the municipal
          securities sold; and

               (C) no Standard & Poor's Security Discount Factor will be applied
          to cash or to funds to be received for sales of municipal securities
          if such funds are due within five business days of such Valuation
          Date. For purposes of calculating Standard & Poor's Eligible
          Securities as of any Valuation Date, funds to be received for sales of
          municipal securities is the book value of such funds to be received
          for municipal securities sold as of or prior to such Valuation Date.
          For purposes of the foregoing, anticipation notes rated "SP-1" or, if
          not rated by Standard & Poor's, rated "VMIG-1" by Moody's, which do
          not mature or have a demand feature exercisable in 30 days and which
          do not have a long-term rating, shall be considered to be short-term
          municipal securities.

          (d) Hedging Transactions. The Fund will enter into futures and options
     transactions only for hedging purposes and not for leveraging or
     speculative purposes. So long as Moody's is rating the Preferred Shares,
     the Fund will not enter into a futures or options

                                      A-44
<PAGE>   60

     transaction unless, after giving effect to such futures or options
     transactions, the Rating Agency Required Asset Coverage is met and the Fund
     will not write any anticipatory call options pursuant to which the Fund
     hedges the anticipated purchase of an asset prior to the completion of such
     purchase. For the purpose of determining the Rating Agency Value of Rating
     Agency Required Assets, assets held for initial and variation margin will
     have an Adjusted Value of zero.

               So long as Moody's is rating the Preferred Shares, the Fund will
          not enter into futures contracts with respect to individual securities
          and will not write put or call options on futures contracts. Also, any
          contracts for index based futures or options transactions entered into
          by the Fund shall expire on the first or second succeeding settlement
          date under such contracts.

               (i) Options Transactions. A purchase of a put or call option by
          the Fund, whether in particular securities or on futures contracts,
          will have no effect on the Value of the Rating Agency Required Assets
          except to the extent of premiums paid and profits received. The Fund
          will write only exchange-traded covered call options which are traded
          on exchanges which have been approved by Moody's. If the Fund writes a
          covered call option, the security or futures contract deliverable upon
          the exercise of the option will have an Adjusted Value of zero unless
          the option expires within [44] days, in which case such security or
          futures contract will have an Adjusted Value equal to the lesser of
          the call price specified in such call option and the Adjusted Value,
          if any, that the security would have disregarding the existence of the
          option. In addition, if the Fund writes a covered call option, 10% of
          the exercise price of the covered call option will be a liability of
          the Fund for purposes of determining the Rating Agency Value of Rating
          Agency Required Assets. The Fund will write only exchange-traded put
          options which are traded on exchanges which have been approved by
          Moody's. If the Fund writes a put option with respect to any security,
          the put price will be a liability of the Fund for purposes of
          determining the Rating Agency Value of the Rating Agency Required
          Assets.

               (ii) Futures Transactions. So long as Moody's is rating the
          Preferred Shares the Fund will only enter into futures contracts with
          respect to indices of rates applicable to municipal securities and
          U.S. Treasury bonds which are traded on exchanges which have been
          approved by Moody's. If the Fund enters into a long or short futures
          contract with respect to an index of

                                      A-45
<PAGE>   61

          rates applicable to securities, that futures contract will, so
          long as Standard & Poor's is rating the Preferred Shares, be
          considered a liability for purposes of determining the Rating Agency
          Value of Rating Agency Required Assets in an amount equal to 30%, in
          the case of an index of rates applicable to municipal securities, and
          25%, in the case of an index of rates applicable to U.S. Treasury
          bonds, of the settlement value of such futures contract. So long as
          Moody's is rating the Preferred Shares, the Fund may not enter into
          short futures contracts with respect to (A) an index of rates
          applicable to municipal securities if the market value of all such
          futures contracts owned by the Fund exceeds 100% of the principal
          amount of all Moody's Eligible Municipal Securities owned by the Fund
          with a rating of "Baa" or better from Moody's less the market value of
          all short futures contracts with respect to an index of rates
          applicable to U.S. Treasury bonds, or (B) an index of rates applicable
          to U.S. Treasury bonds if the market value of all such futures
          contracts owned by the Fund exceeds 10% of the principal amount of all
          Moody's Eligible Municipal Securities owned by the Fund with a rating
          of "Aaa" from Moody's, 50% of the principal amount of all Moody's
          Eligible Municipal Securities owned by the Fund with a rating of "Aa"
          from Moody's, or 90% of the principal amount of all Moody's Eligible
          Municipal Securities owned by the Fund with each of the ratings of "A"
          or "Baa" from Moody's less the market value of all short futures
          contracts with respect to an index of rates applicable to municipal
          securities. In addition, the Fund may enter into a futures contracts
          only if (W) after entering into such contract, the total number of
          futures contracts owned by the Fund with respect to an index of rates
          applicable to municipal securities does not exceed 1,000, (X) the
          market value of all such futures contracts owned by the Fund with
          respect to any index of rates applicable to municipal securities does
          not, after the purchase of such contract, exceed an amount equal to
          10% of the daily rolling average trading volume of such futures
          contracts for the previous month, (Y) the market value of all such
          futures contracts owned by the Fund with respect to an index of rates
          applicable to U.S. Treasury bonds does not, after entering into such
          contract, exceed 10% of the daily rolling average trading volume of
          such contracts for the previous month, and (Z) the market value of all
          futures contracts owned by the Fund with respect to indices of rates
          applicable to securities does not, after the purchase of such
          contract, exceed 35% of the aggregate Market Value of the
          Fund's total assets. So long as Moody's is rating the Preferred
          Shares, the Fund will maintain, in a segregated account, cash equal to
          the face value of all open long

                                      A-46
<PAGE>   62

          futures contracts plus 5% of the market value of such contracts. Such
          cash will have an Adjusted Value of zero.

               So long as Standard & Poor's is rating the Preferred Shares, the
          Fund will be obligated to liquidate positions in futures contracts
          with respect to indices of rates applicable to securities if, on two
          successive Evaluation Dates, the Rating Agency Required Asset Coverage
          is not met and on the second of those two Evaluation Dates the Fund
          was required to make a variation margin deposit. Any such liquidation
          shall be made in an amount sufficient to enable the Fund to meet the
          Rating Agency Required Asset Coverage as of such second Evaluation
          Date, or in whole. The Fund will liquidate each open futures contract
          with respect to an index of rates to U.S. Treasury bonds by the last
          day of the month prior to the month in which such contract expires.
          The Fund will liquidate each open futures contract with respect to an
          index of rates applicable to municipal securities by the fifth
          Business Day of the month in which such contract expires. In addition,
          so long as Moody's is rating the Preferred Shares, the Fund will
          liquidate each Bond Buyer Municipal Bond Index contract if the amount
          of open interest in all such contracts fall below 5,000 contracts.

               So long as Standard & Poor's and Moody's are rating the Preferred
          Shares, the Fund will only engage in those futures or options
          transactions explicitly described above.

          (e) When-Issued and Forward Delivery Purchases. If the Fund purchases
     securities on a "when-issued" or "forward delivery" basis, the cash or
     securities segregated by the Fund to satisfy its purchase obligations will
     have an Adjusted Value of zero. The contract to purchase will have an
     Adjusted Value of zero unless the settlement date is within [44] 49 days,
     in which case the contract to purchase will have an Adjusted Value equal to
     the lesser of the purchase price and the Adjusted Value, if any, the
     security contracted to the purchase would have it were owned by the Trust.

          (f) Borrowings. So long any Preferred Shares are outstanding and
     Moody's and Standard & Poor's, or both, are rating the Preferred Shares,
     the Fund will not borrow money unless it has received written confirmation
     from Moody's or Standard & Poor's, or both, as appropriate, that the
     proposed borrowing would not impair the ratings then assigned by such
     ratings agency to the Preferred Shares. Notwithstanding the foregoing, the
     Fund may, without obtaining the written confirmation described above,
     borrow money for the purpose of clearing securities transactions if (i) the
     Ratings Agency Required Asset Coverage would continue to

                                      A-47
<PAGE>   63

     be satisfied after giving effect to such borrowing 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 per centum of the value of the total assets of the Fund 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.

     8. Conversion. The Preferred Shares, by their terms shall not be
convertible into or exchangeable for, shares of another series or class.

     9. Certification. No certificate representing Preferred Shares shall be
issued for less than a Unit.

     10. Liquidation Rights

          (a) Payment Upon Liquidation. In the event of a liquidation,
     dissolution or winding up of the Fund, whether voluntary or involuntary,
     the Owners of the Preferred Shares, in preference to the owners of the
     Common Shares but not in preference of any other series or class of
     preferred shares of beneficial interests of the Fund, shall be entitled to
     payment, out of the assets of the Fund or the proceeds thereof available
     for distribution to shareholders after satisfaction of claims of creditors
     of the Fund, of a liquidation distribution in the amount of $5,000 per
     share, plus an amount equal to all accumulated dividends (whether or not
     declared but without interest) to the date payment of such distribution
     shall be made in full or a sum sufficient for the payment thereof shall be
     set apart with the Paying Agent. After payment of the full amount of such
     liquidation distribution, the Owners of the Preferred Shares shall not be
     entitled to any further participation in any distribution of assets of the
     Fund.

          (b) Insufficient Assets. If, upon the liquidation, dissolution or
     winding up of the Fund whether voluntary or involuntary, the assets of the
     Fund or the proceeds thereof available for distribution to shareholders
     after satisfaction of claims of creditors of the Fund shall be insufficient
     to pay in full the liquidation distribution to which the Owners of the
     Preferred Shares or the holders of other preferred shares of beneficial
     interest of the Fund are entitled, such assets or the proceeds thereof
     shall be distributed among the Owners of the Preferred Shares and the
     owners of other preferred shares of beneficial interest ratably, so that
     the amount of the distribution to be made to each Owner and owner of the
     other preferred shares of beneficial interest will bear the same ratio to
     the aggregate

                                      A-48
<PAGE>   64

     amount of the distribution to be made to all Owners and owners of the other
     preferred shares of beneficial interest as the aggregate amount of the
     liquidation distribution owed to such Owner and owner of the other
     preferred shares of beneficial interest will bear to the aggregate amount
     of the liquidation distribution owed to all Owners and owners of the other
     preferred shares of beneficial interest.

So long as any Preferred Shares shall remain outstanding, the Fund, in the event
of any liquidation, dissolution or winding up of the Fund, whether voluntary or
involuntary, shall not (i) make any payment or other distribution to the holders
of the Common Shares or (ii) purchase, redeem or otherwise acquire for any
consideration any of the Common Shares, until payment in full shall have been
made to the holders of the Preferred Shares of the liquidation distribution to
which they shall be entitled. Neither the sale, lease or exchange (for cash,
securities or other consideration) of all or substantially all of the property
and assets of the Fund nor the consolidation or merger of the Fund with or into
any other corporation or corporations shall be deemed to be a liquidation,
dissolution or winding up of the Fund, whether voluntary or involuntary, within
the meaning of this paragraph 10; provided that such sale, lease, exchange,
consolidation or merger, by its terms, would not adversely affect the voting
powers, preferences and relative, participating, optional or other special
rights of the holders of the Preferred Shares.

11. Remarketing: Tender for Remarketing

          (a) The Remarketing Agent. The Fund shall take all reasonable action
     necessary so that, at all times, an investment bank, broker, dealer or
     other organization qualified to remarket the Preferred Shares and to
     establish Dividend Periods and Dividend Rates as herein provided shall act
     as Remarketing Agent for the Preferred Shares. On the first day of each
     Dividend Period for each Preferred Share of a series tendered for
     remarketing on such day, the Remarketing Agent shall use its best efforts
     to remarket for the beneficial owners thereof, without charge to such
     beneficial owners, such Preferred Shares, in transactions of at least a
     Unit, at a price of $5,000 per share; provided, however, such Remarketing
     Agent shall not be obligated to remarket such Preferred Shares if there
     shall be a material misstatement or omission in any disclosure document
     used in connection with the remarketing of such Preferred Shares or at any
     time the Remarketing Agent shall have determined that it is not advisable
     to remarket such Preferred Share by reason of any of: (i) a pending or
     proposed change in applicable tax laws, (ii) a material adverse change in
     the financial condition of the Fund, (iii) a banking moratorium, (iv)
     domestic or international hostilities, (v) an amendment of this resolution,
     the Agreement and Declaration or the

                                      A-49
<PAGE>   65

     By-Laws of the Fund which materially and adversely changes the nature of
     the Preferred Shares or the remarketing procedures therefor, (vi) a
     downgrading or withdrawal of the rating on the Preferred Shares, (vii) an
     imposition of material restrictions on the Preferred Shares or any other
     preferred shares of beneficial interest of the Fund or (viii) a failure by
     the Fund, an any Dividend Payment Date for any Preferred Share, to have
     paid, or set apart with the Paying Agent funds for the payment of, the
     dividend payable on such Preferred Share on such date. Should the
     Remarketing Agent not succeed in so remarketing all Preferred Shares of a
     series tendered for remarketing on any date, the Remarketing Agent shall
     select the Preferred Shares of such series to be sold from those tendered
     pro rata or in such other manner as it shall deem appropriate so that no
     beneficial owner of such tendered Preferred Shares shall own less than a
     Unit of such tendered Preferred Shares; provided, however, that the
     Remarketing Agent may own less than a Unit if it shall elect to purchase
     Preferred Shares tendered for remarketing which it shall not have succeeded
     in remarketing. Settlement of transactions will take place on the day of
     remarketing, which is the first day of each Dividend Period, in accordance
     with the normal procedures of the Depository.

          (b) Notice of Preferred Shares to be Retained. Each Preferred Share
     shall be deemed to have been tendered to the Fund (or such agent as the
     Fund may appoint) for sale by remarketing on the day following the last day
     of each Dividend Period, unless the beneficial owner thereof shall have
     given irrevocable notice to the contrary to the Remarketing Agent (or such
     other agent as the Fund may appoint). Any such notice shall be irrevocable
     when given. Such notice, which may be telephonic or written, must be
     delivered to the Remarketing Agent prior to 3:00 p.m., New York City time,
     on the last Business Day of the Dividend Period. The notice from such
     beneficial owner of an election to retain Preferred Shares shall state (i)
     the number of Preferred Shares not to be deemed to have been so tendered
     and (ii) the number of such Preferred Shares which shall be deemed not to
     have been so tendered, which number may not be less than a Unit and may not
     result in such beneficial owner retaining less than a Unit of such
     Preferred Shares.

          (c) Preferred Shares Deemed to have been Tendered. The failure to give
     notice with respect to any Preferred Share as provided in clause (b) of
     this paragraph 11 shall constitute the irrevocable tender for remarketing
     of such Preferred Share. Thereupon, such Preferred Shares shall cease to
     accrue dividends payable to the former beneficial owners thereof, which
     shall have no further rights with respect to such Preferred Shares, except
     the right to receive any

                                      A-50
<PAGE>   66

     previously declared but unpaid dividends thereon and the proceeds of the
     remarketing thereof.

          (d) Funds for Purchase of Preferred Shares. Preferred Shares tendered
     for remarketing as provided in this paragraph 11 shall be purchased solely
     from the proceeds received from the purchasers of such Preferred Shares in
     a remarketing. Neither the Fund nor the Remarketing Agent (nor any other
     agent which the Fund may appoint) shall be obligated to provide funds to
     make payment to the beneficial owners of Preferred Shares so tendered.

12. Restrictions on the Common Shares. So long as any Preferred Shares shall be
outstanding, the Fund shall not declare, pay or set aside for payment any
dividend or other distribution (other than a dividend or distribution paid in
shares of, or options, warrants or rights to subscribe for or purchase Common
Shares) in respect of any Common Share, or call for redemption, redeem purchase
or otherwise acquire for consideration any Common Shares, unless:

          (a) such transaction is on an EvaluationValuation Date;

          (b) immediately thereafter the 1940 Act Coverage and the Rating Agency
     Required Asset Coverage would be met as of such EvaluationValuation Date;

          (c) full cumulative dividends on the Preferred Shares and any other
     preferred shares of beneficial interest of the Fund for all past Dividend
     Periods ended on or prior to the EvaluationValuation Date shall have been
     declared and paid (or declared and a sum sufficient for the payment of such
     dividends shall have been set apart with the Paying Agent for payment); and

          (d) the Fund has redeemed the full number of Preferred Shares required
     to be redeemed by any provision for mandatory redemption contained in
     paragraph 4(b) above.

13. Other Securities. While the Preferred Shares are outstanding, the Fund will
not issue any other series or class of securities which, if issued, would
violate the provisions of Section 18 of the 1940 Acts.

14. Other Rights. Except as provided by law, the Preferred Shares shall not have
any designation preference, or relative, participating, optional or other
special rights, or qualifications, limitations or restrictions, other than as
set forth in this resolution.

15. Limitation on Liability. A copy of the Agreement and Declaration is on file
with the Secretary of the Commonwealth of Massachusetts, and is hereby agreed
that this instrument is executed on behalf of the Board of Trustees of the Fund
as trustees and not individually and that the obligations of this instrument are
not binding upon any of the trustees, officers

<PAGE>   67

or holders of Common or Preferred Shares of the Fund individually but are
binding only upon the assets and property of the Fund.

16. Board of Trustees Interpretation. To the extent permitted by applicable law,
the Board of Trustees may interpret or adjust the provisions of this Certificate
of Designation to resolve any inconsistency or ambiguity or to remedy any formal
defect, and may amend this Certificate of Designation with respect to any series
of Preferred Shares prior to the issuance of shares of such series.

17. No Fractional Shares. No fractional Preferred Shares shall be issued.

18. Status of Preferred Shares Redeemed, Exchanged or Otherwise Acquired by the
Fund. Preferred Shares which are redeemed, exchanged or otherwise acquired by
the Fund shall return to the status of authorized and unissued Preferred Shares
without designation as to series.

19. Headings Not Determinative. The headings contained in this Certificate of
Designation are for convenience of reference only and shall not affect the
meaning or interpretation of this Certificate of Designation.

20. Notices. All notices or communications, unless otherwise specified in the
By-laws of the Fund or this Certificate of Designation, shall be sufficiently
given if in writing and delivered in person or mailed by first-class mail,
postage prepaid.

IN WITNESS WHEREOF, this instrument has been executed for and on behalf and in
the name of the Fund by its officers thereunto duly authorized on
