                     Subject To Completion -- ________, 1999

                                  $____________

                       EATON VANCE MUNICIPAL INCOME TRUST
                        Auction Preferred Shares ("APS")
                                _________ Shares
                    Liquidation Preference $25,000 Per Share

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

      Eaton Vance  Municipal  Income  Trust (the  "Trust") is a newly  organized
closed-end fund. The Trust's  investment  objective is to provide current income
exempt from regular  federal income tax. This income will be earned by investing
primarily in investment grade municipal securities.  The Trust may also invest a
portion of its assets in higher risk,  higher yielding  municipal  securities of
lesser quality. There is no assurance that the Trust will achieve its investment
objective. See "Investment Objective, Policies and Risks" beginning at page ___.

The Trust's  investment  adviser is Eaton Vance Management ("Eaton Vance" or the
"Adviser").  Eaton Vance manages 45 different municipal bond funds with combined
assets of about $8 billion.

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

      The  Broker-Dealers  (as defined herein) may maintain a secondary  trading
market in the APS outside of Auctions;  however,  they have no  obligation to do
so,  and there can be no  assurance  that a  secondary  market  for the APS will
develop  or, if it does  develop,  that it will  provide  holders  with a liquid
trading market (I.E.,  trading will depend on the presence of willing buyers and
sellers and the trading  price is subject to variables to be  determined  at the
time of the trade by the Broker-Dealers).  The APS will not be registered on any
stock exchange or on any automated quotation system. An increase in the level of
interest rates,  particularly during any Long Term Dividend Period,  likely will
have an adverse  effect on the secondary  market price of the APS, and a selling
shareholder  may sell APS  between  Auctions  at a price  per share of less than
$25,000. -------------

      NEITHER THE  SECURITIES AND EXCHANGE  COMMISSION NOR ANY STATE  SECURITIES
COMMISSION HAS APPROVED OR  DISAPPROVED  OF THESE  SECURITIES OR PASSED UPON THE
ADEQUACY OF THIS PROSPECTUS.  ANY  REPRESENTATION  TO THE CONTRARY IS A CRIMINAL
OFFENSE.

(1) Plus accumulated dividends, if any, from the Date of Original Issue. 
(2) The Trust and the Adviser have agreed to indemnify the  Underwriter  against
    certain  liabilities  under the  Securities  Act of 1933,  as  amended.  See
    "Underwriting."
(3) Offering expenses payable by the Trust,  estimated at $ , will be reimbursed
    by the Underwriter. See "Underwriting."

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

      The shares of APS are offered by the  Underwriter,  subject to prior sale,
when, as and if issued by the Trust and accepted by the Underwriter,  subject to
approval of certain  legal  matters by counsel for the  Underwriter  and certain
other  conditions.  The  Underwriter  reserves the right to withdraw,  cancel or


                                       i

modify such offer and to reject  orders in whole or in part. It is expected that
one  certificate  for each series of the APS will be delivered to the nominee of
The Depository Trust Company on or about _______, 1999.






                  THE DATE OF THIS PROSPECTUS IS _______, 1999.

THE  INFORMATION  IN THIS  PROSPECTUS IS NOT COMPLETE AND MAY BE CHANGED.  THESE
SECURITIES  MAY NOT BE SOLD  UNTIL THE  REGISTRATION  STATEMENT  FILED  WITH THE
SECURITIES AND EXCHANGE COMMISSION IS EFFECTIVE. THIS PROSPECTUS IS NOT AN OFFER
TO SELL THESE  SECURITIES AND IS NOT SOLICITING AN OFFER TO BUY THESE SECURITIES
IN ANY STATE WHERE THE OFFER OR SALE IS NOT PERMITTED.








                                       ii

(CONTINUED FROM THE PREVIOUS PAGE)

      Dividends on the Auction Preferred Shares (the "APS") of the Trust offered
hereby will be cumulative from the Date of Original Issue and payable commencing
on _______,  1999 (an "Initial Dividend Payment Date") and,  generally,  on each
succeeding __________, subject to certain exceptions.

      The cash dividend rate (the "Applicable  Rate") on the APS for the Initial
Dividend  Period ending  _______,  1999 will be ____% per annum.  The Applicable
Rate on the APS for each Subsequent  Dividend Period will be determined pursuant
to periodic  auctions  conducted in  accordance  with the  procedures  described
herein and in detail in Appendix D to the  Statement of  Additional  Information
(an "Auction").  Except as otherwise provided herein,  each Subsequent  Dividend
Period for the APS will be a 7-Day  Dividend  Period;  provided,  however,  that
prior to any  Auction,  the Trust may  elect,  subject  to  certain  limitations
described  herein,  upon giving notice to holders  thereof,  a Special  Dividend
Period. See "Description of APS--Dividends."

      The Applicable Rate on the APS for each Subsequent Dividend Period will be
reset on the basis of Bids,  Hold  Orders  and Sell  Orders  placed by  Existing
Holders and Potential  Holders in the Auction conducted on the Business Day next
preceding the  commencement  of such Dividend  Period.  The Applicable Rate that
results  from an Auction for any  Dividend  Period will not be greater  than the
Maximum  Applicable  Rate (as  defined  herein).  See  "Description  of APS--The
Auction--Orders by Beneficial  Owners,  Potential  Beneficial  Owners,  Existing
Holders and Potential Holders."

      The Trust  currently is required to allocate  net capital  gains and other
taxable income, if any, proportionately among its Common Shares and the APS. The
Trust will give notice of the amount of any  taxable  income to be included in a
dividend on shares of APS in the related Auction,  as described  herein,  or, in
limited  circumstances,  include  such  income in a dividend  on the APS without
giving  advance  notice  thereof if it increases  the dividend by an  additional
amount to offset  substantially  the tax effect  thereof.  The amount of taxable
income  allocable to the APS will depend upon the amount of such income realized
by the Trust and other factors but generally is not expected to be  significant.
See "Taxes."

      Each   prospective   purchaser   should  review   carefully  the  detailed
information  regarding the Auction  Procedures  which appears in this Prospectus
and the  Statement of Additional  Information,  including  the  Appendices,  and
should note that (i) an Order  constitutes  an  irrevocable  commitment to hold,
purchase  or sell APS based upon the results of the  related  Auction,  (ii) the
Auctions will be conducted  through telephone  communications,  (iii) settlement
for  purchases  and sales will be on the Business Day  following the Auction and
(iv)  ownership of APS will be maintained  in book-entry  form by or through the
Securities Depository. In certain circumstances, holders of APS may be unable to
sell their APS in an Auction and thus may lack liquidity of investment.  The APS
only may be  transferred  pursuant to a Bid or a Sell Order placed in an Auction
through a Broker-Dealer to the Auction Agent or in the secondary market, if any.

      The APS are  redeemable,  in whole or in part, at the option of the Trust,
on any Dividend  Payment Date (except  during the Initial  Dividend  Period or a
Non-Call Period) at the Optional  Redemption Price per share and will be subject
to mandatory  redemption on dates fixed by the Board of Trustees,  under certain
circumstances, at the Mandatory Redemption Price per share.

      If the Trust  fails to pay on any  Dividend  Payment  Date (or  within the
applicable grace period) the full amount of any dividend or the redemption price
of the APS called for  redemption,  the Applicable Rate will not be based on the
results of an Auction but instead will be equal to the Non- Payment  Period Rate
until    such    failure    to   pay   is    cured.    See    "Description    of
APS--Dividends--Non-Payment Period; Late Charge."

      This Prospectus  sets forth  concisely  information you should know before
investing  in the APS.  Please  read  and  retain  this  Prospectus  for  future
reference.  A Preliminary  Statement of Additional  Information dated _________,

      The  following  summary is  qualified  in its entirety by reference to the
more detailed information included elsewhere in this Prospectus.  Certain of the
capitalized  terms used herein are defined in the  Glossary  that appears at the
end of this Prospectus.

- --------------------------------------------------------------------------------
THE TRUST..............Eaton  Vance Municipal  Income Trust,  Inc. (the "Trust")
                       is a recently  organized  closed-end fund. The  Trust was
                       organized as a  Massachusetts  business trust on December
                       10,  1998,  and   has  registered  under  the  Investment
                       Company Act of  1940,  as amended (the "1940  Act").  The
                       Trust's  principal  office   is  located  at  24  Federal
                       Street,  Boston,  MA 02110,  and  its telephone number is
                       1-800-225-6265.

                       The Trust  commenced  operations on January __, 1999 upon
                       the  closing of an initial  public  offering of shares of
                       its Common  Shares.  The proceeds of such  offering  were
                       approximately $______ after the payment of organizational
                       and offering  expenses.  In  connection  with the initial
                       public  offering  of  the  Trust's  Common  Shares,   the
                       underwriter  was  granted an option to  purchase up to an
                       additional  shares  to  cover  over-allotments.  See "The
                       Trust."

INVESTMENT  OBJECTIVE  The Trust's  investment  objective is to provide  current
AND POLICIES.........  income exempt from regular federal income tax. Securities
                       will be  purchased  and sold in an effort to  maintain  a
                       competitive  yield on the  Common  Shares  and to enhance
                       return  based upon the relative  value of the  securities
                       available in the  marketplace.  Investments  are based on
                       Eaton Vance Management's ("Eaton Vance" or the "Adviser")
                       research  and ongoing  credit  analysis,  the  underlying
                       materials  for  which  are  generally  not  available  to
                       individual  investors.  An  investment  in the  shares of
                       Auction Preferred Shares (the "APS") of the Trust may not
                       be  appropriate  for  all  investors,  and  there  is  no
                       assurance  that the Trust  will  achieve  its  investment
                       objective                                                
                       
                       During normal market conditions  substantially all of the
                       Trust's  total  assets (at least 80%) will be invested in
                       debt  obligations  issued  by or  on  behalf  of  states,
                       territories and possessions of the United States, and the
                       District of Columbia  and their  political  subdivisions,
                       agencies or  instrumentalities,  the interest on which is
                       exempt  from  regular   federal  income  tax  ("Municipal
                       Obligations").  At least 65% of the Trust's  total assets
                       normally will be invested in Municipal  Obligations rated
                       at  least  investment  grade  at the  time of  investment
                       (which are those rated Baa or higher by Moody's Investors
                       Service,  Inc.  ("Moody's")  or BBB or  higher  by either
                       Standard & Poor's  Ratings  Group ("S&P") or by FitchIBCA
                       ("Fitch")), or, if unrated,  determined by Eaton Vance to
                       be of at least  investment  grade  quality.  From time to
                       time,  the  Trust  may  hold  a  significant   number  of
                       Municipal   Obligations   not   rated  by  a   nationally
                       recognized   statistical  rating  organization   ("Rating
                       Agency").  When the Trust  invests in  unrated  Municipal
                       Obligations  it may be more  dependent  on Eaton  Vance's
                       research  capabilities  than  when it  invests  in  rated
                       Municipal Obligations.

                       The  Trust may  invest  up to 35% of its total  assets in
                       Municipal  Obligations  rated below investment grade (but
                       not,  with respect to more than 30% of the Trust's  total
                       assets,  lower than B by all Rating  Agencies  rating the
                       obligation) and unrated Municipal Obligations  considered
                       to be of comparable quality by Eaton Vance. Investment in
                       Municipal  Obligations of below  investment grade quality
                       involves  special  risks as compared  with  investment in
                       higher grade Municipal  Obligations.  These risks include
                       greater  sensitivity  to  a  general  economic  downturn,
                       greater market price volatility and less secondary market
                       trading.  Securities  rated  below  investment  grade are
                       commonly  known  as "junk  bonds."  Such  securities  are


                                        1

                       regarded,  on balance, as predominantly  speculative with
                       respect to the issuer's ability to pay interest and repay
                       principal owed.

                       The Trust may invest to a significant  extent in residual
                       interest  municipal  bonds  known  as  inverse  floaters.
                       Compared to similar fixed rate municipal bonds, the value
                       of these  bonds  will  fluctuate  to a greater  extent in
                       response  to changes  in  prevailing  long-term  interest
                       rates.  Moreover,  the income earned on residual interest
                       municipal  bonds will fluctuate in response to changes in
                       prevailing  short-term  interest  rates.  Thus, when such
                       bonds are held by the  Trust,  an  increase  in short- or
                       long-term market interest rates will adversely affect the
                       income  received from such bonds. To the extent the Trust
                       has preferred shares  outstanding,  including the APS, an
                       increase  in  short-term  rates  would also  result in an
                       increased cost of leverage,  which would adversely affect
                       the Trust's income available for  distribution.  Although
                       the Trust is not limited with  respect to its  investment
                       in residual interest  municipal bonds, the Trust does not
                       intend  initially  to  invest  more than 10% of its total
                       assets in such bonds.

                       The  Trust  may  purchase  and  sell  various   kinds  of
                       financial   futures   contracts   and  related   options,
                       including  futures contracts and related options based on
                       various debt securities and securities  indices,  to seek
                       to  hedge  against   changes  in  interest  rates,  as  a
                       substitute  for the purchase of  securities  or for other
                       risk management purposes.

                       Interest   income  from   certain   types  of   municipal
                       obligations  may be a tax preference item for purposes of
                       the  federal  alternative  minimum  tax (the  "AMT")  for
                       individual   investors.    Distributions   to   corporate
                       investors  of  certain   interest   income  may  also  be
                       indirectly  subject  to  the  AMT.  THE  APS  MAY  NOT BE
                       SUITABLE FOR INVESTORS SUBJECT TO THE AMT.

INVESTMENT ADVISER     Eaton Vance,  a  wholly-owned  subsidiary  of Eaton Vance

                       administrator.  The Adviser manages 3 national  municipal
                       funds,  32  single  state  municipal  funds,  10  limited

                       Arrangements."                                           
                       
THE OFFERING.......... The Trust is offering an aggregate of _____ shares of APS
                       at a purchase price of $25,000 per share plus accumulated
                       dividends,  if any, from the Date of Original Issue.  The
                       APS  are  being  offered  by  ___________________  or the
                       "Underwriter     as    lead     representative").     See
                       "Underwriting."
                       
                       The APS  will  be  Preferred  Shares  of the  Trust  that
                       entitle their holders to receive cash dividends at a rate
                       per  annum  that  may vary  for the  successive  Dividend
                       Periods for such shares. In general,  except as described
                       below, each Dividend Period for the APS subsequent to the
                       Initial Dividend Period will be seven days in length. The
                       Applicable Rate for a particular  Dividend Period will be
                       determined  by an Auction  conducted  on the Business Day
                       next preceding the start of such Dividend Period.

                       Through  their  Broker-Dealers,   Beneficial  Owners  and
                       Potential  Beneficial  Owners of APS may  participate  in
                       Auctions  therefor,  although,  except  in the  case of a
                       Special  Dividend Period,  Beneficial  Owners desiring to
                       continue  to hold  all of  their  APS  regardless  of the
                       Applicable   Rate   resulting   from  Auctions  need  not
                       participate.  For an  explanation  of  Auctions  and  the
                       method  of   determining   the   Applicable   Rate,   see
                       "Description of APS--The Auction."

                       Except as  described  herein,  investors  in APS will not
                       receive  certificates  representing  ownership  of  their
                       shares. Ownership of APS will be maintained in book-entry
                       form by the Securities  Depository or its nominee for the
                       account of the  investor's  Agent Member.  The investor's
                       Agent  Member,  in turn,  will  maintain  records of such
                       investor's  beneficial  ownership  of  APS.  Accordingly,
                       references  herein  to  an  investor's  investment  in or
                       purchase,  sale or  ownership  of APS  are to  purchases,
                       sales or ownership of those shares by Beneficial Owners.

                       After  the  Initial  Dividend  Period,   each  Subsequent
                       Dividend  period  for the APS will  generally  consist of
                       seven  days  (a  "7-day  Dividend   Period");   provided,
                       however,  that prior to any Auction, the Trust may elect,
                       subject to certain  limitations  described  herein,  upon
                       giving  notice to  holders  thereof,  a Special  Dividend
                       Period.  A Special  Dividend  Period is a Dividend Period
                       consisting  of a  specified  number of days  (other  than
                       seven),  evenly  divisible  by seven and not  fewer  than
                       seven nor more than 364 (a "Short Term Dividend  Period")
                       or a Dividend Period  consisting of a specified period of
                       one whole year or more but not greater than five years (a
                       "Long  Term  Dividend  Period").  Dividends  on  the  APS
                       offered hereby are  cumulative  from the Date of Original
                       Issue and are  payable  when,  as and if  declared by the
                       Board of  Trustees  of the  Trust,  out of funds  legally
                       available  therefor,  commencing on the Initial  Dividend
                       Payment  Date and, in the case of Dividend  Periods  that
                       are  not  Special  Dividend  Periods,  dividends  will be
                       payable  generally  on  each  succeeding   _____________,
                       subject to certain exceptions.

                       Dividends for the APS will be paid through the Securities
                       Depository (the  Depository  Trust Company or a successor
                       securities depository) on each Dividend Payment Date. The
                       Securities  Depository's normal procedures provide for it
                       to  distribute  dividends  in  same-day  funds  to  Agent
                       Members,  who are in turn  expected  to  distribute  such
                       dividends to the person for whom they are acting as agent
                       in accordance with the  instructions of such person.  See
                       "Description of APS -- Dividends."

                       For each Subsequent  Dividend  Period,  the cash dividend
                       rate on the APS will be the Applicable  Rate that Bankers
                       Trust  Corporation   ("Bankers  Trust"  or  the  "Auction
                       Agent") or any successor)  advises the Trust has resulted
                       from an Auction.  See  "Description of APS -- Dividends."
                       The first  Auction for the APS is scheduled to be held on
                       the ending  date for the Initial  Dividend  Period as set
                       forth above.

                       The Amended  By-Laws provide that until the Trust gives a
                       Request  for  Special  Dividend  Period  and the  related
                       Notice of Special  Dividend  Period,  only 7-Day Dividend
                       Periods will be  applicable  to the APS.  While the Trust
                       does not  currently  intend to give a Request for Special
                       Dividend  Period with respect to the APS, it may so elect
                       in  the  future   subject  to,  and  on,  the  conditions
                       discussed  under  "Description of the APS -- Dividends --
                       Notification of Dividend Period."

                       A Special  Dividend  Period will not be effective for the
                       APS unless Sufficient  Clearing Bids exist at the Auction
                       in respect of such Special Dividend Period. If Sufficient
                       Clearing  Bids do not exist at such  Auction for the APS,
                       the  Dividend  Period  commencing  on  the  Business  Day
                       succeeding such Auction will be a 7-Day Dividend  Period,
                       and the holders of the APS of  outstanding  prior to such
                       Auction  will be required to continue to hold such shares
                       for such Dividend Period. In addition,  the Trust may not
                       give a Notice of Special  Dividend Period with respect to


                                        3
<PAGE>

                       the APS,  or if the Trust  has given a Notice of  Special
                       Dividend  Period for the APS,  the Trust will be required
                       to give a Notice of Revocation in respect  thereof if (i)
                       either the 1940 Act APS Asset  Coverage is not  satisfied
                       or the Trust fails to maintain S&P  Eligible  Assets with
                       an aggregate  Discounted  Value at least equal to the APS
                       Basic Maintenance Amount, in each case on each of the two
                       Valuation  Dates  immediately  preceding the Business Day
                       prior to the  related  Auction  Date  for the  APS,  (ii)
                       sufficient funds for the payment of dividends  payable on
                       the immediately succeeding Dividend Payment Date have not
                       been irrevocably  deposited with the Auction Agent by the
                       close of business on the third Business Day preceding the
                       related  Auction Date, or (iii) the  Broker-Dealers  have
                       given the Trust  notice that it is not  advisable to hold
                       an Auction in respect of a Special  Dividend  Period.  In
                       such event, the next succeeding Dividend Period will be a
                       7-Day Dividend Period.

ADVANCE  NOTICE  OF    Dividends  paid by the  Trust,  to the  extent  paid from
ALLOCATION OF TAXABLE  tax-exempt income earned on Municipal  Obligations,  will
INCOME; INCLUSION OF   be exempt  from  Federal  income  taxes,  subject  to the
TAXABLE INCOME   IN    possible  application of the federal  alternative minimum
DIVIDENDS............. tax.  However,  the Trust is  required  to  allocate  net
                       capital gains and other income subject to regular Federal
                       income taxes, if any,  proportionately  among the Trust's
                       Common  Shares  and APS in  accordance  with the  current
                       position  of  the  Internal  Revenue  Service   described
                       herein.  The Trust will notify the  Auction  Agent of the
                       amount of any net capital gains or other  taxable  income
                       to be  included  in any  dividend on the APS prior to the
                       Auction   establishing   the  Applicable  Rate  for  such
                       dividend.  The  Auction  Agent in turn will  notify  each
                       Broker-Dealer  whenever it receives  any such notice from
                       the  Trust,  and  each   Broker-Dealer  will  notify  its
                       Beneficial  Owners and Potential  Beneficial  Owners,  as
                       provided  in  its  Broker-Dealer  Agreement.  In  limited
                       circumstances,  the Trust also may include such income in
                       a  dividend  on the APS  without  giving  advance  notice
                       thereof if it  increases  the  dividend by an  additional
                       amount to offset  the tax effect  thereof.  The amount of
                       taxable income  allocable to the APS will depend upon the
                       amount  of such  income  realized  by the Trust and other
                       factors, but generally is not expected to be significant.
                       See  "Taxes"  and  "Description  of APS -- The Auction --
                       Auction  Date;  Advance  Notice of  Allocation of Taxable
                       Income; Inclusion of Taxable Income in Dividends."       
                       
ADDITIONAL             If the  Trust  retroactively  allocates  any net  capital
DIVIDENDS........      gains or  other income subject to regular  Federal income
                       taxes to the APS  without  having  given  advance  notice
                       thereof as  described  above,  which may only happen when
                       such  allocation is made as a result of the redemption of
                       all  or  a  portion  of  the   outstanding   APS  or  the
                       liquidation  of the Trust,  the Trust  will make  certain
                       payments  to holders of the APS to which such  allocation
                       was made to offset  substantially the tax effect thereof.
                       In no other  instances will the Trust be required to make
                       payments  to  holders of the APS to offset the tax effect
                       of any reallocation of net capital gains or other taxable
                       income.  See  "Description of  APS--Dividends--Additional
                       Dividends" and "Taxes."

DETERMINATION OF       Except during  a Non-Payment  Period, the Applicable Rate
MAXIMUM APPLICABLE     for  any  Dividend  Period  for the APS  will not be more
RATES................. than  the  Maximum  Applicable  Rate  applicable  to such
                       shares.  The  Maximum  Applicable  Rate  for the APS will
                       depend on the credit  rating  assigned to such shares and
                       on the  duration  of the  Dividend  Period.  The  Maximum
                       Applicable Rate will be the Applicable  Percentage of the
                       Reference Rate. The Reference Rate is (i) with respect to
                       any  Dividend  Period or any Short Term  Dividend  Period
                       having 28 or fewer  days,  the  higher of the  applicable
                       "AA"  Composite  Commercial  Paper  Rate and the  Taxable
                       Equivalent of the Short-Term  Municipal  Obligation Rate,
                       (ii) with  respect  to any  Short  Term  Dividend  Period

                       Dividend Period,  the applicable U.S. Treasury Note Rate.
                       The Applicable Percentage will be determined based on (i)
                       the credit rating assigned on such date to the APS by S&P
                       (or,  if S&P shall not make such  rating  available,  the
                       equivalent of such rating by a Substitute  Rating Agency)
                       and (ii) whether the Trust has provided  notification  to
                       the Auction Agent prior to the Auction  establishing  the
                       Applicable  Rate for any dividend  that net capital gains
                       or other taxable income will be included in such dividend
                       on the shares of APS as follows:

                       There is no  minimum  Applicable  Rate in  respect of any
                       Dividend Period.

                       The Applicable  Rate for any Dividend  Period  commencing
                       during  any  Non-Payment  Period,  and the  rate  used to
                       calculate the late charge described under "Description of
                       APS--Dividends--Non-   Payment   Period;   Late  Charge,"
                       initially  will be 200% of the Reference Rate (or 275% of
                       such rate if the Trust has provided  notification  to the
                       Auction  Agent  prior  to the  Auction  establishing  the
                       Applicable  Rate for any dividend  that net capital gains
                       or other taxable income will be included in such dividend
                       on APS).

AUCTION PROCEDURES.... Unless  otherwise  permitted  by  the  Trust,  Beneficial
                       Owners and  Potential  Beneficial  Owners of APS may only
                       participate  in Auctions  through  their  Broker-Dealers.
                       Broker-Dealers will submit the Orders of their respective
                       customers  who  are   Beneficial   Owners  and  Potential
                       Beneficial  Owners  to  the  Auction  Agent,  designating
                       themselves  as  Existing  Holders  in  respect  of shares
                       subject to Orders  submitted or deemed  submitted to them
                       by Beneficial  Owners and as Potential Holders in respect
                       of  shares  subject  to  Orders   submitted  to  them  by
                       Potential  Beneficial Owners. On or prior to each Auction
                       Date for the APS (the  Business  Day next  preceding  the
                       first day of each Dividend Period), each Beneficial Owner
                       may submit Orders to its Broker-Dealer as follows:       
                       
                       o  Hold  Order--indicating  its  desire  to hold  the APS
                          without  regard  to the  Applicable  Rate for the next
                          Dividend Period for such shares.
                       o  Bid--indicating  its desire to hold the APS,  provided
                          that the Applicable  Rate for the next Dividend Period
                          for such  shares  is not less  than the rate per annum
                          specified in such Bid.
                       o  Sell  Order--indicating  its  desire  to sell  the APS
                          without  regard  to the  Applicable  Rate for the next
                          Dividend Period for such shares.

                       A Beneficial  Owner may submit  different types of Orders
                       to its Broker-Dealer with respect to the APS then held by
                       such Beneficial Owner,  provided that the total number of
                       shares of the APS  covered by such Orders does not exceed


                                        5
<PAGE>

                       the  number  of APS held by such  Beneficial  Owner.  If,
                       however,   a   Beneficial   Owner   offers   through  its
                       Broker-Dealer  to  purchase  additional  shares of APS in
                       such Auction, such Beneficial Owner, for purposes of such
                       offer to purchase additional shares, will be treated as a
                       Potential  Beneficial Owner as described  below.  Bids by
                       Beneficial Owners through their Broker-Dealers with rates
                       per annum higher than the Maximum Applicable Rate will be
                       treated as Sell  Orders.  A Hold Order (in the case of an
                       Auction  relating  to a  Dividend  Period  which is not a
                       Special Dividend Period) and a Sell Order (in the case of
                       an Auction  relating to a Special  Dividend Period) shall
                       be  deemed  to  have  been   submitted  on  behalf  of  a
                       Beneficial Owner if an Order with respect to the APS then
                       held by such Beneficial  Owner is not submitted on behalf
                       of such  Beneficial  Owner for any reason,  including the
                       failure  of a  Broker-Dealer  to submit  such  Beneficial
                       Owner's Order to the Auction Agent.

                       Potential  Beneficial  Owners  of  APS  may  submit  Bids
                       through  their  Broker-Dealers  in  which  they  offer to
                       purchase APS,  provided that the Applicable  Rate for the
                       next Dividend Period for such shares is not less than the
                       rate  per  annum  specified  in  such  Bid.  A  Bid  by a
                       Potential  Beneficial  Owner with a rate per annum higher
                       than the Maximum Applicable Rate will not be considered.

                       Neither  the  Trust  nor  the   Auction   Agent  will  be
                       responsible for a Broker-Dealer's  failure to comply with
                       any of the foregoing.

                       A Broker-Dealer  also may hold APS for its own account as
                       a  Beneficial  Owner.  A  Broker-Dealer  thus may  submit
                       Orders to the Auction  Agent as a  Beneficial  Owner or a
                       Potential  Beneficial Owner and therefore  participate in
                       an Auction as an Existing  Holder or Potential  Holder on
                       behalf of both itself and its customers.  An Order placed
                       with the Auction Agent by a Broker-Dealer  as an Existing
                       Holder  or a  Potential  Holder  as  or  on  behalf  of a
                       Beneficial Owner or a Potential  Beneficial Owner, as the
                       case may be,  will be  treated  in the same  manner as an
                       Order placed with a Broker-Dealer  by a Beneficial  Owner
                       or a Potential Beneficial Owner.  Similarly,  any failure
                       by a  Broker-Dealer  to  submit to the  Auction  Agent an
                       Order in respect  of any APS held by it or its  customers
                       who are  Beneficial  Owners  will be  treated in the same
                       manner as a Beneficial  Owner's  failure to submit to its
                       Broker-Dealer  an Order in  respect of APS held by it, as
                       described above. Inasmuch as a Broker-Dealer participates
                       in an Auction as an Existing Holder or a Potential Holder
                       only to represent the interests of a Beneficial  Owner or
                       Potential  Beneficial Owner,  whether it be a customer or
                       itself,   all   discussion   herein   relating   to   the
                       consequences  of an  Auction  for  Existing  Holders  and
                       Potential   Holders  also   applies  to  the   underlying
                       beneficial ownership interests represented thereby.

                       If Sufficient Clearing Bids exist in an Auction (that is,
                       in  general,  the  number  of  APS  subject  to  Bids  by
                       Potential  Holders  with rates equal to or lower than the
                       Maximum  Applicable  Rate is at least equal to the number
                       of APS subject to Sell Orders by Existing  Holders),  the
                       Applicable  Rate  will  be  the  lowest  rate  per  annum
                       specified  in  the  Submitted  Bids  which,  taking  into
                       account such rate per annum and all lower rates per annum
                       bid by Existing  Holders  and  Potential  Holders,  would
                       result in Existing  Holders and Potential  Holders owning
                       all of the APS available for purchase in the Auction.  If
                       Sufficient  Clearing  Bids  do not  exist,  the  Dividend
                       Period next following the Auction automatically will be a
                       7-Day Dividend Period and the Applicable Rate will be the
                       Maximum  Applicable  Rate,  and in such  event,  Existing
                       Holders that have  submitted Sell Orders will not be able
                       to sell in the Auction  all,  and may not be able to sell
                       any,  APS subject to such Sell Orders.  Thus,  in certain
                       circumstances, Existing Holders and, thus, the Beneficial
                       Owners  they   represent   may  not  have   liquidity  of
                       investment. If all Existing Holders submit (or are deemed

                       to  have  submitted)  Hold  Orders  in  an  Auction,  the
                       Dividend Period next following the Auction  automatically
                       shall be the same  length  as the  immediately  preceding
                       Dividend  Period,  and the Applicable Rate will be 40% of
                       the Reference  Rate (as defined under  "Determination  of
                       Maximum Applicable Rates" above) in effect on the date of
                       the  Auction  (or  60% of  such  rate  if the  Trust  has
                       provided  notification  to the Auction Agent prior to the
                       Auction establishing the Applicable Rate for any dividend
                       that net capital  gains or other  taxable  income will be
                       included in such dividend on APS).

                       The Auction  Procedures  include a pro rata allocation of
                       shares  for  purchase  and sale,  which may  result in an
                       Existing Holder selling or holding, or a Potential Holder
                       purchasing,  a number of APS that is less than the number
                       of  APS  specified  in  its  Order.  To  the  extent  the
                       allocation  has  this  result,  a  Broker-Dealer  will be
                       required to make appropriate pro rata  allocations  among
                       its customers and itself.

                       A Sell Order by an  Existing  Holder will  constitute  an
                       irrevocable offer to sell the APS subject thereto,  and a
                       Bid placed by an Existing  Holder also will constitute an
                       irrevocable  offer to sell the APS subject thereto if the
                       rate per annum  specified  in the Bid is higher  than the
                       Applicable Rate  determined in the Auction,  in each case
                       at a price per share equal to $25,000.  A Bid placed by a
                       Potential Holder will constitute an irrevocable  offer to
                       purchase  the APS  subject  thereto if the rate per annum
                       specified  in such  Bid is  less  than  or  equal  to the
                       Applicable Rate determined in the Auction.  Settlement of
                       purchases and sales will be made on the next Business Day
                       (also a Dividend  Payment  Date) after the  Auction  Date
                       through the Securities  Depository.  Purchasers will make
                       payment  through their Agent Members in same-day funds to
                       the Securities  Depository against delivery by book-entry
                       to their Agent Members.  The Securities  Depository  will
                       make payment to the sellers'  Agent Members in accordance
                       with the Securities Depository's normal procedures, which
                       now  provide  for   payment  in   same-day   funds.   See
                       "Description of APS--The Auction."

ASSET MAINTENANCE..... Under the Amended  By-Laws,  the Trust must  maintain (i)
                       S&P Eligible  Assets having in the aggregate a Discounted
                       Value at least equal to the APS Basic Maintenance  Amount
                       and (ii) 1940 Act APS Asset  Coverage  of at least  200%.
                       See "Description of APS--Asset Maintenance."             
                       
                       The Trust estimates that, based on the composition of its
                       portfolio at _________, 1999, 1940 Act APS Asset Coverage
                       with respect to shares of APS would be approximately ___%
                       immediately  after the issuance of the APS offered hereby
                       in  an  amount  representing  approximately  __%  of  the
                       Trust's capital.

                       The Discount  Factors and guidelines for  calculating the
                       Discounted Value of the Trust's portfolio for purposes of
                       determining  whether the APS Basic Maintenance Amount has
                       been satisfied have been established by S&P in connection
                       with the  Trust's  receipt of ratings on the APS on their
                       Date of Original  Issue of AAA from S&P. See  "Investment
                       Objective and Policies--Rating Agency Guidelines."

MANDATORY REDEMPTION.. If the APS Basic  Maintenance  Amount or the 1940 Act APS
                       Asset Coverage is not maintained or restored as specified
                       herein, the APS will be subject to mandatory  redemption,
                       out of funds legally available therefor, at the Mandatory
                       Redemption  Price of  $25,000  per  share  plus an amount
                       equal to  dividends  thereon  (whether  or not  earned or
                       declared)  accumulated  but  unpaid to the date fixed for


                                        7

                       redemption.  In addition,  holders of APS may be entitled
                       to  receive   Additional   Dividends   in  the  event  of
                       redemption of such APS to the extent provided herein. See
                       "Description  of  APS--Dividends--Additional  Dividends."
                       Any such redemption will be limited to the minimum number
                       of APS  necessary  to restore  the APS Basic  Maintenance
                       Amount  or the 1940 Act APS Asset  Coverage,  as the case
                       may be.  The  Trust's  ability  to make such a  mandatory
                       redemption  may be  restricted  by the  provisions of the
                       Investment  Company  Act of 1940,  as amended  (the "1940
                       Act").  See  "Description  of  APS--Redemption--Mandatory
                       Redemption."                                             
                       
OPTIONAL REDEMPTION... The APS  are redeemable at the option of the Trust,  as a
                       whole or  in part,  on any Dividend  Payment Date (except
                       during   the  Initial   Dividend  Period  or  a  Non-Call
                       Period)  at the Optional  Redemption Price of $25,000 per
                       share,   plus  an  amount  equal  to   dividends  thereon
                       (whether  or not  earned or  declared)   accumulated  but
                       unpaid  to  the  date  fixed  for  redemption  plus   the
                       premium,  if any,  resulting  from the  designation of  a

                       unpaid dividends (whether or not earned or declared). See
                       "Description  of  APS--Liquidation  Rights." In addition,
                       holders  of APS may be  entitled  to  receive  Additional
                       Dividends in the event of the liquidation of the Trust as

                       Additional Dividends."

RATINGS..............  It  is a  condition  to  their  issuance  that the APS be
                       issued  with  a rating of AAA from S&P.  See  "Investment
                       Objective and Policies--Rating Agency Guidelines."

VOTING RIGHTS........  The  1940 Act  requires  that the  holders of APS and any

                       have the  right to elect at least   two  trustees  at all
                       times and to elect a  majority  of  the  trustees  at any

                       Preferred Shares are  unpaid.  The holders of APS and any
                       other Preferred  Shares  will vote as a separate class on
                       certain  other   matters as  required  under the  Trust's
                       Agreement  and   Declaration  of Trust  ("Declaration  of
                       Trust")   and   the  1940  Act.   See   "Description   of

                                    THE TRUST

      Eaton Vance Municipal  Income Trust (the "Trust") is a recently  organized
closed-end  fund. The Trust was organized as a  Massachusetts  business trust on
December 10, 1998, and has registered under the Investment  Company Act of 1940,
as amended  (the "1940  Act").  The  Trust's  principal  office is located at 24
Federal Street, Boston, MA 02110, and its telephone number is 1-800-225-6265.

      The Trust commenced  operations on January __, 1999 upon the closing of an
initial  public  offering of shares of its Common  Shares.  The proceeds of such
offering  were  approximately  $______ after the payment of  organizational  and
offering expenses. In connection with the initial public offering of the Trust's
Common  Shares,  the  underwriter  was  granted an option to  purchase  up to an
additional shares to cover over-allotments.

      Certain of the capitalized term used in this Prospectus are defined in the
Glossary that appears at the end of this Prospectus.

                                 USE OF PROCEEDS

      [THE ESTIMATED NET PROCEEDS OF THIS OFFERING WILL BE $__________ AFTER THE
PAYMENT OF OFFERING EXPENSES  ](estimated to be $__________ ) and the sales load

      The net proceeds of the offering will be invested in  accordance  with the
Trust's  investment  objective  and policies  during a period  estimated  not to
exceed  three  months  from the offer and sale of such APS  depending  on market
conditions  and  the  availability  of  appropriate  securities.   Pending  such
investment,  it is anticipated  that the proceeds will be invested in short-term
tax-exempt securities. See "Investment Objective and Policies."

                    INVESTMENT OBJECTIVE, POLICIES AND RISKS

INVESTMENT OBJECTIVE

      The Trust's investment  objective is to provide current income exempt from
regular federal income tax. This income will be earned by investing primarily in
investment grade Municipal Obligations. Securities will be purchased and sold in
an effort to maintain a  competitive  yield on the Common  Shares and to enhance
return  based  upon  the  relative  value  of the  securities  available  in the
marketplace.  Investments are based on Eaton Vance's research and ongoing credit
analysis,  the  underlying  materials  for which are  generally not available to
individual investors.

      Eaton Vance seeks to find Municipal  Obligations of high quality that have
been undervalued in the marketplace.  Eaton Vance's research specialists examine
credit histories,  revenue sources, total debt histories, capital structures and
other data. This research  capability is important  because many  obligations in
which the Trust will invest will not be rated or listed on a national securities
exchange,  and the amount of public information  available about such securities
will be limited. The Trust intends to emphasize the research that is critical to
discovering  value while  avoiding  undue credit risk. The Trust will attempt to
enhance performance opportunities by seeking to remain fully invested.

INVESTMENT POLICIES - GENERAL COMPOSITION OF THE TRUST


                                       11
<PAGE>

      During normal market  conditions,  substantially  all of the Trust's total
assets  (at least  80%) will be  invested  in debt  obligations  issued by or on
behalf of states,  territories  and  possessions of the United  States,  and the
District   of   Columbia   and  their   political   subdivisions,   agencies  or
instrumentalities,  the interest on which is exempt from regular  federal income
tax  ("Municipal  Obligations").  At least 65% of the Trust's  total assets will
normally be invested in Municipal Obligations rated at least investment grade at
the time of investment (which are those rated Baa or higher by Moody's or BBB or
higher by either S&P or by Fitch), or, if unrated,  determined by Eaton Vance to
be of at least investment grade quality. From time to time, the Trust may hold a
significant amount of Municipal Obligations not rated by a nationally recognized
statistical rating  organization  ("Rating  Agency").  When the Trust invests in
unrated  Municipal  Obligations,  it may be  more  dependent  on  Eaton  Vance's
research capacities than when it invests in rated Municipal Obligations.

      The  Trust  may  invest  up to  35%  of  its  total  assets  in  Municipal
Obligations rated below investment grade (but not, with respect to more than 30%
of the Trust's  total  assets,  lower than B by all Rating  Agencies  rating the
obligation)  and unrated  Municipal  Obligations  considered to be of comparable
quality by Eaton  Vance.  No such  securities  will be in default at the time of
purchase.  Investment in Municipal Obligations of below investment grade quality
involves  special  risks as compared with  investment in higher grade  Municipal
Obligations.  These risks  include  greater  sensitivity  to a general  economic
downturn,  greater market price  volatility and less secondary  market  trading.
Securities rated below investment grade are commonly known as "junk bonds." Such
securities are regarded,  on balance, as predominantly  speculative with respect
to the  issuer's  ability  to pay  interest  and repay  principal  owed.  See "-
Additional  Risk  Considerations."  For a  description  of municipal  obligation
ratings, see the Appendix A to the Statement of Additional Information.

      The foregoing credit quality policies apply only at the time a security is
purchased,  and the Trust is not  required to dispose of a security in the event
that a Rating Agency downgrades its assessment of the credit  characteristics of
a particular  issue.  In determining  whether to retain or sell such a security,
Eaton Vance may consider such factors as Eaton Vance's  assessment of the credit
quality of the issuer of such  security,  the price at which such security could
be sold and the  rating,  if any,  assigned  to such  security  by other  Rating
Agencies.

      Municipal  Obligations include bonds, notes and commercial paper issued by
a  municipality  for a wide  variety of both  public and private  purposes,  the
interest  on which is, in the  opinion of  issuer's  counsel (or on the basis of
other  reliable  authority),  exempt from  regular  federal  income tax.  Public
purpose  municipal bonds include general  obligation and revenue bonds.  General
obligation  bonds are backed by the taxing  power of the  issuing  municipality.
Revenue  bonds are backed by the revenues of a project or facility,  or from the
proceeds of a specific revenue source.  Some revenue bonds are payable solely or
partly  from  funds  which are  subject  to annual  appropriations  by a state's
legislature.  Municipal notes include bond  anticipation,  tax  anticipation and
revenue  anticipation  notes.  Bond,  tax and  revenue  anticipation  notes  are
short-term  obligations that will be retired with the proceeds of an anticipated
bond issue, tax revenue or facility revenue, respectively.

      Some of the  securities in which the Trust  invests may include  so-called
"zero-coupon" bonds, whose values are subject to greater fluctuation in response
to changes in market  interest  rates  than bonds that pay  interest  currently.
Zero-coupon  bonds are issued at a significant  discount from face value and pay
interest  only at  maturity  rather  than at  intervals  during  the life of the
security.  The Trust is required to take into  account  income from  zero-coupon
bonds on a current basis,  even though it does not receive that income currently
in cash, and the Trust is required to distribute substantially all of its income
for each taxable year.  Thus,  the Trust may have to sell other  investments  to
obtain cash needed to make income distributions.

      The Trust may invest in residual  interest  municipal bonds whose interest
rates bear an inverse  relationship to the interest rate on another  security or
the value of an index ("inverse  floaters").  An investment in inverse  floaters
may  involve  greater  risk than an  investment  in a fixed rate  bond.  Because
changes in the interest rate on the other security or index inversely affect the
residual  interest paid on the inverse floater,  the value of an inverse floater
is generally more volatile than that of a fixed rate bond. Inverse floaters have
interest rate  adjustment  formulas which  generally  reduce or, in the extreme,
eliminate the interest paid to the Trust when  short-term  interest  rates rise,


                                       12
<PAGE>

and increase the interest paid to the Trust when short-term interest rates fall.
Inverse  floaters have varying  degrees of  liquidity,  and the market for these
securities is relatively new and volatile. These securities tend to underperform
the market for fixed rate bonds in a rising interest rate environment,  but tend
to  outperform  the market for fixed rate  bonds when  interest  rates  decline.
Shifts in long-term interest rates may, however,  alter this tendency.  Although
volatile,  inverse  floaters  typically offer the potential for yields exceeding
the yields available on fixed rate bonds with comparable credit quality, coupon,
call provisions and maturity.  These  securities  usually permit the investor to
convert the floating rate to a fixed rate (normally adjusted downward), and this
optional  conversion feature may provide a partial hedge against rising rates if
exercised at an opportune  time.  Although the Trust is not limited with respect
to its  investment  in residual  interest  municipal  bonds,  the Trust does not
intend initially to invest more than 10% of its assets in such bonds.

      The Trust may purchase  municipal bonds that are  additionally  secured by
insurance,  bank credit  agreements,  or escrow accounts.  The credit quality of
companies which provide such credit  enhancements will affect the value of those
securities.  Although the insurance feature reduces certain financial risks, the
premiums for insurance and the higher market price paid for insured  obligations
may reduce the Trust's current yield.  Insurance generally will be obtained from
insurers  with a  claims-paying  ability  rated Aaa by  Moody's or AAA by S&P or
Fitch. The insurance  feature does not guarantee the market value of the insured
obligations or the Trust's net asset value.

      The Trust has adopted  certain  fundamental  investment  restrictions  set
forth in the  Statement  of  Additional  Information  which  may not be  changed
without a Shareholder vote. Except for such restrictions and the 80% requirement
set forth  above,  the  investment  objective  and  policies of the Trust may be
changed by the Board of Trustees without Shareholder action.

ADDITIONAL INVESTMENT PRACTICES

      WHEN-ISSUED   SECURITIES.   The  Trust  may  purchase   securities   on  a
"when-issued"  basis,  which means that payment and  delivery  occur on a future
settlement  date. The price and yield of such  securities are generally fixed on
the date of commitment to purchase.  However, the market value of the securities
may fluctuate  prior to delivery and upon delivery the  securities  may be worth
more or less than the Trust agreed to pay for them. The Trust may be required to
maintain a segregated  account of liquid  assets equal to  outstanding  purchase
commitments.  The Trust may also  purchase  instruments  that give the Trust the
option to purchase a municipal obligation when and if issued.

      FUTURES  TRANSACTIONS.  The Trust may purchase  and sell various  kinds of
financial futures contracts and options thereon to seek to hedge against changes
in  interest  rates or as a  substitute  for the  purchase  of  securities.  For
example,  futures  contracts  can be used to  reduce  the  additional  long-term
interest rate risk the Trust bears by holding residual interest municipal bonds.
Futures contracts may be based on various debt securities and securities indices
(such as the Municipal  Obligation  Index traded on the Chicago Board of Trade).
Such  transactions  involve a risk of loss or depreciation  due to unanticipated
adverse  changes in  securities  prices,  which may exceed the  Trust's  initial
investment  in these  contracts.  The Trust will only  purchase or sell  futures
contracts  or related  options  in  compliance  with the rules of the  Commodity
Futures Trading Commission.  These transactions involve transaction costs. There
can be no assurance  that the Eaton Vance's use of futures will be  advantageous
to the Trust.  Distributions  by the Trust of any gains  realized on the Trust's
transactions  in futures  and  options on futures  will be  taxable.  The rating
agency guidelines with respect to the APS limits the use of these  transactions.
See "Investment Objective, Policies and Risks -- Rating Agency Guidelines."

      INVESTMENT  COMPANY  SECURITIES.  The Trust may purchase  common shares of
closed-end  investment  companies that have a similar  investment  objective and
policies  to the  Trust.  In  addition  to  providing  tax-exempt  income,  such
securities may provide capital appreciation. Such investments, which may also be
leveraged  and  subject to the same  risks as the Trust,  will not exceed 10% of
total  assets,  and no such company will be affiliated  with Eaton Vance.  These
companies bear fees and expenses that the Trust will incur indirectly.

ADDITIONAL RISK CONSIDERATIONS

      INTEREST RATE AND MARKET RISK. The prices of Municipal Obligations tend to
fall as interest  rates rise.  Securities  that have longer  maturities  tend to
fluctuate more in price in response to changes in market  interest  rates.  This
risk is usually greater among Municipal  Obligations  with longer  maturities or


                                       13
<PAGE>

durations  and when  residual  interest  municipal  bonds are held by the Trust.
Although the Trust has no policy  governing  the  maturities or durations of its
investments, the Trust expects that it will invest in a portfolio of longer term
securities.  This means that the Trust  will be subject to greater  market  risk
(other  things  being  equal)  than  a fund  investing  solely  in  shorter-term
securities.  Market  risk  is  often  greater  among  certain  types  of  income
securities,  such as  zero-coupon  bonds,  which  do not make  regular  interest
payments.  As interest rates change,  these bonds often  fluctuate in price more
than higher quality bonds that make regular interest payments. Because the Trust
may  invest in these  types of income  securities,  it may be subject to greater
market risk than a fund that invests only in current interest paying securities.

      The  Trust  may  invest  to a  significant  extent  in  residual  interest
municipal  bonds  known as inverse  floaters.  Compared  to  similar  fixed rate
municipal  bonds, the value of these bonds will fluctuate to a greater extent in
response to changes in prevailing long-term interest rates. Moreover, the income
earned on  residual  interest  municipal  bonds will  fluctuate  in  response to
changes in prevailing  short-term interest rates. Thus, when such bonds are held
by the Trust,  an increase in short- or  long-term  market  interest  rates will
adversely  affect the income  received from such bonds or the net asset value of
Trust shares.

      INCOME  RISK.  The  income  investors  receive  from  the  Trust  is based
primarily on the interest it earns from its  investments,  which can vary widely
over the short and long-term. If interest rates drop, investors' income from the
Trust over time could drop as well if the Trust purchases  securities with lower
interest  coupons.  This risk is magnified when prevailing  short-term  interest
rates increase and the Trust holds residual interest municipal bonds.

      CALL RISK. If interest rates fall, it is possible that issuers of callable
bonds with high  interest  coupons  will "call" (or prepay)  their bonds  before
their  maturity  date. If a call were exercised by the issuer during a period of
declining  interest  rates,  the Trust is likely to replace such called security
with a lower yielding security.

      CREDIT  RISK.  Municipal  debt  obligations  are  subject  to the  risk of
non-payment of scheduled  interest  and/or  principal.  Such  non-payment  would
result in a reduction of income to the Trust and a reduction in the value of the
security  experiencing  non-payment.  Securities rated below investment grade or
unrated  securities of  comparable  quality  ("lower  quality  securities")  are
subject to the risk of an issuer's  inability  to meet  principal  and  interest
payments  on the  obligations  ("credit  risk") and may also be subject to price
volatility due to such factors as interest rate  sensitivity,  market perception
of the  creditworthiness  of the issuer and general  market  liquidity  ("market
risk").  The prices of lower quality securities are also more likely to react to
real or perceived  developments affecting market and credit risk than are prices
of investment  grade quality  securities  ("higher quality  securities"),  which
react  primarily  to  movements  in the  general  level of interest  rates.  The
investments in the Trust's portfolio will have speculative characteristics.

      As indicated  above, the Trust may invest up to 35% of its total assets in
Municipal  Obligations  rated below  investment  grade (but not, with respect to
more than 30% of its total assets,  lower than B by all Rating  Agencies  rating
the  obligation)  and  comparable  unrated  obligations.  Such  obligations  are
commonly  called  "junk  bonds"  and will have  speculative  characteristics  in
varying  degrees.  While such  obligations  may have some quality and protective
characteristics,   these  characteristics  can  be  expected  to  be  offset  or
outweighed by uncertainties or major risk exposures to adverse conditions. Eaton
Vance  seeks to  minimize  the  risks of  investing  in below  investment  grade
securities  through  professional  investment  analysis,  attention  to  current
developments  in  interest  rates and  economic  conditions,  and  industry  and
geographic  diversification.  When the Trust  invests in lower  rated or unrated
Municipal Obligations, the achievement of the Trust's goals is more dependent on
the Eaton Vance's  ability than would be the case if the Trust were investing in
Municipal Obligations in the higher rating categories.  In evaluating the credit
quality of a  particular  issue,  whether  rated or  unrated,  Eaton  Vance will
normally take into consideration, among other things, the financial resources of
the issuer  (or,  as  appropriate,  of the  underlying  source of funds for debt
service),  its  sensitivity  to economic  conditions  and trends,  any operating
history of and the community support for the facility financed by the issue, the
ability of the issuer's  management  and  regulatory  matters.  Eaton Vance will
attempt to reduce the risks of investing in the lowest investment  grade,  below
investment  grade and comparable  unrated  obligations  through active portfolio
management,  credit analysis and attention to current developments and trends in
the economy and the financial markets.

      Increases  in interest  rates and  changes in the  economy  may  adversely
affect  the  ability  of  issuers of lower  grade  municipal  securities  to pay
interest and to repay principal, to meet projected financial goals and to obtain


                                       14
<PAGE>

additional  financing.  In the event  that an issuer of  securities  held by the
Trust  experiences  difficulties  in the timely payment of principal or interest
and such issuer seeks to restructure the terms of its borrowings,  the Trust may
incur  additional  expenses and may determine to invest  additional  assets with
respect to such issuer or the project or projects to which the Trust's portfolio
securities  relate.  Further,  the Trust may incur  additional  expenses  to the
extent  that it is required  to seek  recovery  upon a default in the payment of
interest or the repayment of principal on its portfolio holdings,  and the Trust
may be unable to obtain full recovery thereof.

      To the extent that there is no  established  retail market for some of the
lower grade municipal securities in which the Trust may invest,  trading in such
securities  may  be  relatively   inactive.   The  Adviser  is  responsible  for
determining the net asset value of the Trust,  subject to the supervision of the
Board of Trustees of the Trust.  During periods of reduced market  liquidity and
in the absence of readily  available market quotations for lower grade municipal
securities  held in the Trust's  portfolio,  the ability of the Adviser to value
the Trust's  securities becomes more difficult and the Adviser's use of judgment
may play a greater role in the  valuation of the Trust's  securities  due to the
reduced  availability  of  reliable  objective  data.  The  effects  of  adverse
publicity and investor  perceptions  may be more  pronounced  for securities for
which no  established  retail  market  exists as  compared  with the  effects on
securities for which such a market does exist.  Further, the Trust may have more
difficulty  selling such securities in a timely manner and at their stated value
than would be the case for  securities  for which an  established  retail market
does exist

      Municipal Obligations held by the Trust that are of below investment grade
quality but which,  subsequent to the  assignment of such rating,  are backed by
escrow  accounts  containing  U.S.  Government  obligations may be determined by
Eaton  Vance to be of  investment  grade  quality  for  purposes  of the Trust's
investment  policies.  The Trust may retain in its portfolio an obligation  that
declines in quality,  including  defaulted  obligations,  if such  retention  is
considered desirable by Eaton Vance. In the case of a defaulted obligation,  the
Trust may incur additional expense seeking recovery of its investment.

      Changes in the credit quality of the issuers of Municipal Obligations held
by the Trust will affect the principal  value of (and possibly the income earned
on) such obligations.  In addition, the value of such securities are affected by
changes in general  economic  conditions and business  conditions  affecting the
relevant  economic  sectors.  Changes by Rating  Agencies in their  ratings of a
security  and in the  ability of the issuer to make  payments of  principal  and
interest  may also  affect the value of the Trust's  investments.  The amount of
information about the financial condition of an issuer of Municipal  Obligations
may not be as extensive as that made available by corporations  whose securities
are publicly traded.

      The Trust may invest in municipal leases,  and participations in municipal
leases.  The obligation of the issuer to meet its obligations  under such leases
is often subject to the appropriation by the appropriate legislative body, on an
annual or other basis, of funds for the payment of the obligations.  Investments
in municipal  leases are thus subject to the risk that the legislative body will
not make the  necessary  appropriation  and the  issuer  will not  otherwise  be
willing or able to meet its obligation.

      CONCENTRATION.  The Trust may  invest  25% or more of its total  assets in
Municipal  Obligations of issuers located in the same state (or U.S.  territory)
or in Municipal  Obligations  in the same  economic  sector,  including  without
limitation  the  following:   lease  rental   obligations  of  state  and  local
authorities;  obligations  dependent  on  annual  appropriations  by  a  state's
legislature  for  payment;  obligations  of  state  and  local  housing  finance
authorities,   municipal  utilities  systems  or  public  housing   authorities;
obligations of hospitals or life care facilities;  or industrial  development or
pollution  control bonds issued for electric utility  systems,  steel companies,
paper companies or other purposes.  This may make the Trust more  susceptible to
adverse economic,  political,  or regulatory  occurrences affecting a particular
state  or  economic  sector.  For  example,  health  care  related  issuers  are
susceptible to Medicaid  reimbursement  policies,  and national and state health
care legislation.

      LIQUIDITY RISK. At times, a substantial  portion of the Trust's assets may
be  invested in  securities  as to which the Trust,  by itself or together  with
other accounts managed by Eaton Vance and its affiliates,  holds a major portion
of all of such securities. Under adverse market or economic conditions or in the
event of adverse  changes in the  financial  condition of the issuer,  the Trust


                                       15
<PAGE>

could find it more difficult to sell such  securities  when Eaton Vance believes
it  advisable  to do so or may be able to sell  such  securities  only at prices
lower than if such securities were more widely held. In such  circumstances,  it
may also be more  difficult to determine the fair value of such  securities  for
purposes of computing the Trust's net asset value.

      The secondary  market for some  Municipal  Obligations  (including  issues
which are privately  placed with the Trust) is less liquid than that for taxable
debt  obligations  or other more  widely  traded  Municipal  Obligations.  These
include residual interest  municipal bonds. No established  resale market exists
for certain of the  Municipal  Obligations  in which the Trust may  invest.  The
market for obligations  rated below  investment  grade is also likely to be less
liquid than the market for higher rated obligations.  As a result, the Trust may
be unable to  dispose  of these  Municipal  Obligations  at times  when it would
otherwise wish to do so at the prices at which they are valued.

      A secondary  market may be subject to  irregular  trading  activity,  wide
bid/ask  spreads  and  extended  trade  settlement  periods.  The  Trust  has no
limitation on the amount of its assets which may be invested in securities which
are not readily  marketable or are subject to restrictions on resale.  The risks
associated  with  illiquidity  are  particularly  acute in situations  where the
Trust's  operations  require  cash,  such as if the Trust tenders for its Common
Shares,  and  may  result  in  the  Trust  borrowing  to  meet  short-term  cash
requirements.

      NON-DIVERSIFICATION.  The  Trust  has  registered  as a  "non-diversified"
investment  company  under  the  1940  Act so that,  subject  to its  investment
restrictions  and applicable  federal income tax  diversification  requirements,
with respect to 50% of its total assets,  it will be able to invest more than 5%
(but not more than 25%) of the value of its total assets in the  obligations  of
any single issuer.  To the extent the Trust invests a relatively high percentage
of its assets in obligations  of a limited number of issuers,  the Trust will be
more susceptible than a more widely diversified investment company to any single
corporate, economic, political or regulatory occurrence.

      YEAR  2000  COMPLIANCE.  The  Trust  could be  adversely  affected  if the
computer systems used by the Adviser and other service providers do not properly
process and calculate  date-related  information and data from and after January
1, 2000.  This is  commonly  known as the "Year 2000  Problem."  Eaton  Vance is
taking steps that it believes are  reasonably  designed to address the Year 2000
Problem with respect to computer  systems that it uses and to obtain  reasonable
assurances  that  comparable  steps are being taken by the  Trust's  other major
service providers. At this time, there can be no assurance that these steps will
be sufficient to avoid any adverse impact to the Trust.

      In addition,  it is possible that the markets for municipal  securities in
which the Trust  invests may be  detrimentally  affected  by  computer  failures
throughout  the financial  services  industry  beginning on or before January 1,
2000.  Improperly  functioning trading systems may result in settlement problems
and liquidity  issues.  In addition,  corporate and governmental data processing
errors may result in  production  problems  for  individual  issuers and overall
economic  uncertainties.  Earnings  of  individual  issuers  will be affected by
remediation costs,  which may be substantial and may be reported  inconsistently
in financial statements.  Accordingly,  the Trust's investments may be adversely
affected.

RATING AGENCY GUIDELINES

      The Trust intends that, so long as APS are outstanding, the composition of
its portfolio will reflect guidelines  established by S&P in connection with the
Trust's  receipt  of a rating  for  such  shares  on or  prior to their  Date of
Original Issue of at least AAA from S&P. S&P,  which is a Rating Agency,  issues
ratings for various securities reflecting the perceived creditworthiness of such
securities.  The  guidelines  described  below  have  been  developed  by S&P in
connection with issuances of asset-backed and similar securities, including debt
obligations  and variable rate  Preferred  Shares,  generally on a  case-by-case
basis through  discussions with the issuers of these securities.  The guidelines
are  designed to ensure that assets  underlying  outstanding  debt or  Preferred
Shares will be varied  sufficiently and will be of sufficient quality and amount
to justify investment grade ratings. The guidelines do not have the force of law
but have been  adopted  by the Trust in order to  satisfy  current  requirements
necessary for S&P to issue the above-described  ratings for shares of APS, which
ratings generally are relied upon by institutional  investors in purchasing such
securities.  The guidelines provide a set of tests for portfolio composition and
asset coverage that supplement (and in some cases are more restrictive than) the
applicable  requirements  under the 1940 Act.  See  "Description  of  APS--Asset
Maintenance."


                                       16
<PAGE>

      The Trust  intends to maintain a  Discounted  Value for its  portfolio  at
least equal to the APS Basic Maintenance  Amount.  S&P has established  separate
guidelines  for  determining  Discounted  Value.  To the extent  any  particular
portfolio  holding does not satisfy the applicable  rating agency's  guidelines,
all or a portion of such holding's value will not be included in the calculation
of Discounted  Value.  The S&P  guidelines do not impose any  limitations on the
percentage  of Trust  assets that may be invested in holdings  not  eligible for
inclusion in the calculation of the Discounted Value of the Trust's portfolio.

      Upon any failure to maintain the required Discounted Value, the Trust will
seek to alter the  composition of its portfolio to retain a Discounted  Value at
least  equal to the APS  Basic  Maintenance  Amount on or prior to the APS Basic
Maintenance  Cure  Date,  thereby  incurring  additional  transaction  costs and
possible  losses and/or gains on dispositions  of portfolio  securities.  To the
extent any such failure is not cured in a timely manner, the APS will be subject
to  mandatory  redemption.  See  "Description  of  APS--Asset  Maintenance"  and
"Description of APS--Redemption."  The APS Basic Maintenance Amount includes the
sum of (i) the  aggregate  liquidation  value of APS then  outstanding  and (ii)
certain accrued and projected payment obligations of the Trust. See "Description
of APS--Asset Maintenance."

      The Trust may, but is not required  to, adopt any  modifications  to these
guidelines  that hereafter may be established by S&P.  Failure to adopt any such
modifications, however, may result in a change in the ratings described above or
a withdrawal of ratings altogether.  In addition,  any rating agency providing a
rating  for the shares of APS,  at any time,  may  change or  withdraw  any such
rating.  As set forth in the  Amended  By-Laws,  the  Trust's  Board of Trustees
("Board  of  Trustees"),   without  shareholder  approval,  may  modify  certain
definitions or restrictions  that have been adopted by the Trust pursuant to the
rating agency  guidelines,  provided the Board of Trustees has obtained  written
confirmation  from S&P that any such change  would not impair the  ratings  then
assigned by S&P to the APS.

      As described by S&P, a Preferred  Shares  rating is an  assessment  of the
capacity and willingness of an issuer to pay Preferred Shares  obligations.  The
ratings  on the APS are  not  recommendations  to  purchase,  hold or sell  APS,
inasmuch as the ratings do not comment as to market price or  suitability  for a
particular investor, nor do the rating agency guidelines described above address
the  likelihood  that a holder  of APS will be able to sell  such  shares  in an
Auction.  The ratings are based on current  information  furnished to S&P by the
Trust and the Adviser and information  obtained from other sources.  The ratings
may be  changed,  suspended  or  withdrawn  as a result  of  changes  in, or the
unavailability of, such information.  The Common Shares have not been rated by a
Rating Agency.

      S&P AAA  RATING  GUIDELINES.  The  Discounted  Value  of the  Trust's  S&P
Eligible  Assets is calculated  on each  Valuation  Date.  See  "Description  of
APS--Asset  Maintenance--APS  Basic  Maintenance  Amount." S&P  Eligible  Assets
include cash,  Receivables for Municipal Obligations Sold (as defined below) and
Municipal Obligations eligible for consideration under S&P's current guidelines.
For purposes of calculating the Discounted Value of the Trust's  portfolio under
current S&P guidelines,  the fair market value of Municipal Obligations eligible
for consideration under such guidelines must be discounted by the applicable S&P
Discount  Factor  set  forth  in the  table  below.  The  Discounted  Value of a
Municipal Obligation eligible for consideration under S&P guidelines is the fair
market value thereof divided by the S&P Discount Factor. The S&P Discount Factor
used to  discount  a  particular  Municipal  Obligation  will be  determined  by
reference to (a) (i) the rating by S&P on such  Municipal  Obligation or (ii) in
the event the  Municipal  Obligation  is insured under a Policy and the terms of
the Policy permit the Trust, at its option, to obtain other permanent  insurance
guaranteeing  the timely  payment of interest on such  Municipal  Obligation and
principal thereof to maturity, the S&P insurance claims-paying ability rating of
the  issuer of the  Policy or (iii) in the event  the  Municipal  Obligation  is
insured  under an  insurance  policy  which  guarantees  the  timely  payment of
interest on such Municipal Obligation and principal thereof to maturity, the S&P
insurance claims-paying ability rating of the issuer of the insurance policy and
(b) the S&P Exposure  Period.  The S&P Exposure  Period is the maximum period of
time following a Valuation Date,  including the Valuation Date and the APS Basic
Maintenance Cure Date, that the Trust has to cure any failure to maintain, as of
such Valuation Date, a Discounted  Value for its portfolio at least equal to the
APS Basic Maintenance Amount.

      S&P Discount  Factors  applicable to Municipal  Obligations for a range of
S&P Exposure Periods are set forth below:

      Since the S&P Exposure Period  currently  applicable to the Trust is seven
Business  Days,  the S&P  Discount  Factors  currently  applicable  to Municipal
Obligations  eligible for consideration  under S&P guidelines will be determined
by reference to the factors set forth opposite the exposure period line entitled
"7 Business Days."  Notwithstanding  the foregoing,  (i) the S&P Discount Factor
for  short-term  Municipal  Obligations  will be 115%, so long as such Municipal
Obligations  are rated A-1+ or SP-1+ by S&P and mature or have a demand  feature
exercisable  in 30 days or less, or 125% if such Municipal  Obligations  are not
rated by S&P but are rated VMIG-1, P-1 or MIG-1 by Moody's;  provided,  however,
such  short-term  Municipal  Obligations  rated by Moody's  but not rated by S&P
having a demand  feature  exercisable  in 30 days or less  must be  backed  by a
letter of credit, liquidity facility or guarantee from a bank or other financial
institution  having a  short-term  rating of at least A-1+ from S&P; and further
provided that such  short-term  Municipal  Obligations  rated by Moody's but not
rated by S&P may comprise no more than 50% of short-term  Municipal  Obligations
that  qualify as S&P  Eligible  Assets and (ii) no S&P  Discount  Factor will be
applied to cash or to Receivables for Municipal  Obligations Sold.  "Receivables
for Municipal Obligations Sold," for purposes of calculating S&P Eligible Assets
as of any  Valuation  Date,  means the book value of  receivables  for Municipal
Obligations  Sold as of or prior to such Valuation Date if such  receivables are
due within  five  Business  Days of such  Valuation  Date.  For  purposes of the
foregoing,  Anticipation Notes rated SP-1+ or, if not rated by S&P, 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 Obligations.

      The S&P guidelines  require  certain  minimum issue size and  geographical
diversification  and impose other  requirements  for purposes of determining S&P
Eligible  Assets.  In order to be  considered  S&P  Eligible  Assets,  Municipal
Obligations must:

      (i) be interest bearing and pay interest at least semi-annually;

      (ii) be payable with respect to principal and interest in U.S. dollars;

      (iii) be  publicly  rated BBB or  higher by S&P or,  except in the case of
revenue   anticipation   notes  that  are  grant   anticipation  notes  or  bond
anticipation  notes,  which must be rated by S&P to be included in S&P  Eligible
Assets, if not rated by S&P but rated by Moody's, be rated at least A by Moody's
(provided that such Moody's-rated  Municipal Obligations will be included in S&P
Eligible  Assets  only to the extent  the fair  market  value of such  Municipal
Obligations  does not exceed 50% of the  aggregate  fair market value of the S&P
Eligible Assets. For purposes of determining the S&P Discount Factors applicable
to any such Moody's-rated Municipal Obligations, such Municipal Obligations will
be deemed to have an S&P rating that is one full rating  category lower than its
Moody's rating);

      (iv) not be subject to a covered call or covered put option written by the
Trust;

      (v) not be part of a private placement of Municipal Obligations; and

      (vi) be part of an issue  with an  original  issue  size of at  least  $20
million or, if of an issue with an original issue size below $20 million (but in
no event below $10 million), be issued by an issuer with a total of at least $50
million of securities outstanding.

      Notwithstanding the foregoing:


                                       18
<PAGE>

      (i) Municipal  Obligations of any one issuer or guarantor  (excluding bond
insurers)  will be  considered  S&P Eligible  Assets only to the extent the fair
market  value of such  obligations  does not  exceed 10% of the  aggregate  fair
market  value  of the S&P  Eligible  Assets,  provided  that 2% is  added to the
applicable  S&P  Discount  Factor for every 1% by which the fair market value of
such Municipal  Obligations exceeds 5% of the aggregate fair market value of the
S&P Eligible Assets; and

      (ii) Municipal Obligations issued by issuers in any one state or territory
will be considered S&P Eligible  Assets only to the extent the fair market value
of such Municipal  Obligations  does not exceed 20% of the aggregate fair market
value of S&P Eligible Assets.

      The  Trust  may  include  Municipal  Obligations  as S&P  Eligible  Assets
pursuant to guidelines and restrictions to be established by S&P,  provided that
S&P advises the Trust in writing that such action will not adversely  affect its
then-current rating on the APS.

      As  discussed  herein,   the  Trust  may  engage  in  options  or  futures
transactions.  For so long as any shares of APS are rated by S&P, the Trust will
not  purchase  or sell  financial  futures  contracts,  write,  purchase or sell
options on financial  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  S&P  that  engaging  in  such
transactions will not impair the ratings then assigned to the APS by S&P, except
that the Trust may purchase or sell  financial  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  "S&P  Hedging  Transactions"),
subject to the following limitations:

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

      (ii) the Trust will not  engage in any S&P  Hedging  Transaction  based on
Treasury Bonds (other than Closing  Transactions)  that would cause the Trust at
the time of such  transaction to own or have sold the lesser of (A)  outstanding
financial  futures  contracts based on Treasury Bonds and on the Municipal Index
exceeding  in number 25% of the quotient of the fair market value of the Trust's
total assets  divided by $100,000  ($200,000 in the case of the two-year  United
States Treasury Note) or (B) outstanding  financial  futures  contracts based on
Treasury  Bonds  exceeding  in number 10% of the average  number of daily traded
financial futures contracts based on Treasury Bonds in the 30 days preceding the
time of effecting such transaction as reported by The Wall Street Journal; (iii)
the Trust  will  engage in  Closing  Transactions  to close out any  outstanding
financial  futures  contract that the Trust owns or has sold or any  outstanding
option  thereon  owned by the Trust in the event (A) the Trust does not have S&P
Eligible Assets with an aggregate  Discounted Value equal to or greater than the
APS Basic  Maintenance  Amount on two  consecutive  Valuation  Dates and (B) the
Trust is required to pay Variation Margin on the second such Valuation Date;

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

      (iv) when the  Trust  writes a  financial  futures  contract  or an option
thereon,  it will either  maintain an amount of cash,  cash  equivalents or high
grade (rated A or better by S&P) fixed-income securities in a segregated account
with the Trust's custodian,  so that the amount so segregated plus the amount of
Initial  Margin and Variation  Margin held in the account of or on behalf of the


                                       19
<PAGE>

Trust's broker with respect to such financial  futures contract or option equals
the fair market value of the financial  futures  contract or option,  or, in the
event the Trust  writes a  financial  futures  contract or option  thereon  that
requires  delivery  of an  underlying  security,  it shall hold such  underlying
security in its portfolio.

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

      For so long as the APS are rated by S&P, the Trust, unless it has received
written confirmation from S&P that such action would not impair the ratings then
assigned to the APS by S&P will not (i) borrow  money  except for the purpose of
clearing  transactions  in  portfolio  securities  (which  borrowings  under any
circumstances  shall be limited to the lesser of $10 million and an amount equal
to 5% of the  fair  market  value  of the  Trust's  assets  at the  time of such
borrowings  and  which  borrowings  shall be  repaid  within  60 days and not be
extended or renewed and shall not cause the  aggregate  Discounted  Value of S&P
Eligible Assets to be less than the APS Basic Maintenance  Amount),  (ii) engage
in short sales of securities, (iii) lend any securities, (iv) issue any class or
series of stock ranking prior to or on a parity with the APS with respect to the
payment of dividends or the distribution of assets upon dissolution, liquidation
or winding up of the Trust, (v) reissue any APS previously purchased or redeemed
by the Trust,  (vi) merge or consolidate  into or with any other  corporation or
entity,  (vii)  change the Trust's  pricing  service or (vii)  engage in reverse
repurchase agreements.

      For so long as any  shares  of APS are rated by S&P,  the  Trust  will not
purchase or sell financial futures contracts, write, purchase or sell options on
financial 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 S&P that engaging in such transactions will
not impair the ratings  then  assigned to the APS by S&P,  except that the Trust
may engage in S&P  Hedging  Transactions  subject to the  limitations  described
herein. See "Investment  Objective and  Policies--Rating  Agency Guidelines" and
"--Options and Futures Transactions."

RISKS OF INVESTING IN APS

There are a number of specific factors investors in the APS should consider.

o     The credit ratings of the APS could be reduced while an investor holds the
      APS.

o     Neither  Broker-Dealers nor the Trust are obligated to purchase the APS in
      an Auction or otherwise nor is the Trust required to redeem the APS in the
      event of a failed Auction.

o     If in an Auction for the APS  Sufficient  Clearing Bids do not exist,  the
      Applicable  Rate will be the Maximum  Applicable  Rate, and in such event,
      Beneficial Owners that have submitted Sell Orders will not be able to sell
      in the Auction  all,  and may not be able to sell any,  the APS subject to
      such Sell Orders. Thus, under certain circumstances, Beneficial Owners may
      not have liquidity of investment.

      The  Broker-Dealers  may  maintain a secondary  trading  market in the APS
outside of Auctions;  however, they have no obligation to do so and there can be
no  assurance  that a secondary  market for the APS will  develop or, if it does
develop,  that it will  provide  holders  with a liquid  trading  market  (I.E.,
trading  will  depend on the  presence  of willing  buyers and  sellers  and the
trading  price is subject to variables to be determined at the time of the trade
by the Broker-Dealers).  The APS will not be registered on any stock exchange or
on any automated  quotation  system. An increase in the level of interest rates,
particularly  during any Long Term Dividend Period,  likely will have an adverse
effect on the secondary  market price of the APS, and a selling  shareholder may
sell APS between Auctions at a price per share of less than $25,000.


                                       20
<PAGE>

      The Trust's Amended By-Laws includes provisions that could have the effect
of limiting the ability of other  entities or persons to acquire  control of the
Trust or to change the  composition  of its Board of Trustees and could have the
effect of depriving  holders of Common  Shares of an  opportunity  to sell their
shares at a premium over prevailing  market prices by discouraging a third party
from seeking to obtain control of the Trust. See "Description of Capital Stock--
Certain Provisions of the Declaration of Trust."

                               DESCRIPTION OF APS

      The APS will be  Preferred  Shares that entitle  their  holders to receive
dividends  when,  as and if  declared  by the  Board of  Trustees,  out of funds
legally available therefor, at a rate per annum that may vary for the successive
Dividend Periods for each such series.  After the Initial Dividend Period,  each
Subsequent  Dividend  Period  for the  APS  generally  will be a 7-Day  Dividend
Period;  provided,  however,  that  prior to any  Auction,  the Trust may elect,
subject to certain  limitations  described herein, upon giving notice to holders
thereof,  a  Special  Dividend  Period.  The  Applicable  Rate for a  particular
Dividend  Period will be determined by an Auction  conducted on the Business Day
before  the start of such  Dividend  Period.  Beneficial  Owners  and  Potential
Beneficial  Owners of the APS may  participate in Auctions  therefor,  although,
except in the case of a Special Dividend Period,  Beneficial  Owners desiring to
continue to hold all of their APS  regardless of the  Applicable  Rate resulting
from  Auctions  need not  participate.  For an  explanation  of Auctions and the
method  of  determining  the  Applicable  Rate,  see  "Description  of  APS--The
Auction."

      Except  as  otherwise  required  by law or unless  there is no  Securities
Depository,  all outstanding APS will be represented by one or more certificates
registered in the name of the nominee of the  Securities  Depository  (initially
expected to be Investors Bank & Trust Company  ("IBT"),  and no person acquiring
APS will be entitled to receive a  certificate  representing  such  shares.  See
Appendix C (Auction  Procedures).  As a result,  the  nominee of the  Securities
Depository is expected to be the sole holder of record of the APS.  Accordingly,
each  purchaser  of APS  must  rely  on (i)  the  procedures  of the  Securities
Depository and, if such purchaser is not a member of the Securities  Depository,
such purchaser's Agent Member, to receive  dividends,  distributions and notices
and to exercise  voting rights (if and when  applicable) and (ii) the records of
the  Securities  Depository  and,  if  such  purchaser  is not a  member  of the
Securities Depository, such purchaser's Agent Member, to evidence its beneficial
ownership of the APS.

      When  issued  and sold,  the APS will  have a  liquidation  preference  of
$25,000  per share plus an amount  equal to  accumulated  but  unpaid  dividends
(whether or not earned or declared)  and will be fully paid and  non-assessable.
See  "Description of  APS--Liquidation  Rights." The APS will not be convertible
into  shares  of Common  Shares or other  capital  stock of the  Trust,  and the
holders thereof will have no preemptive  rights.  The APS will not be subject to
any sinking fund but will be subject to redemption at the option of the Trust at
the  Optional  Redemption  Price on any  Dividend  Payment  Date for such series
(except during the Initial Dividend Period and during a Non-Call Period) and, in
certain  circumstances,  will be subject to mandatory redemption by the Trust at
the  Mandatory  Redemption  Price  stated  herein.  See  "Description  of  APS--
Redemption."

      In addition to serving as the Auction Agent in connection with the Auction
Procedures described below, Bankers Trust Corporation  ("Bankers Trust") will be
the transfer agent,  registrar,  dividend  disbursing agent and redemption agent
for the APS. The Auction Agent,  however,  will serve merely as the agent of the
Trust,  acting in  accordance  with the  Trust's  instructions,  and will not be
responsible for any evaluation or verification of any matters certified to it.

      Except  in an  Auction,  the Trust  will  have the  right  (to the  extent
permitted by applicable law) to purchase or otherwise acquire any APS so long as
the Trust is current in the payment of  dividends on APS and on any other shares
of  beneficial  interest  of the  Trust  ranking  on a parity  with the APS with
respect to the payment of dividends or upon liquidation.

      The  following  is a brief  description  of the  terms  of the  APS.  This
description  does not purport to be complete and is subject to and  qualified in
its  entirety  by  reference  to the  Trust's  Declaration  of Trust and Amended
By-Laws,  including the  provisions  thereof  establishing  the APS. The Trust's
Declaration of Trust and the form of Amended By-Laws  establishing  the terms of
the APS have been filed as exhibits to the Registration  Statement of which this
Prospectus is a part.


                                       21

THE AUCTION

      GENERAL.  Holders of the APS will be entitled to receive  cumulative  cash
dividends on their  shares when,  as and if declared by the Board of Trustees of
the Trust, out of the funds legally available therefor,  on the Initial Dividend
Payment Date with respect to the Initial  Dividend  Period and,  thereafter,  on
each  Dividend  Payment  Date  with  respect  to a  Subsequent  Dividend  Period
(generally a period of seven days subject to certain  exceptions set forth under
"Description  of  APS--Dividends--General")  at the rate per annum  equal to the
Applicable Rate for each such Dividend Period.

      The provisions of the Amended  By-Laws  establishing  the terms of the APS
offered  hereby will provide that the Applicable  Rate for each Dividend  Period
after the Initial  Dividend  Period therefor will be equal to the rate per annum
that the Auction  Agent  advises has resulted on the Business Day  preceding the
first  day of  such  Dividend  Period  due  to  implementation  of  the  auction
procedures set forth in the Amended By-Laws (the "Auction  Procedures") in which
persons  determine  to hold or offer to  purchase  or sell the APS.  The Auction
Procedures   are  attached  as  Appendix  D  to  the   Statement  of  Additional
Information.  Each periodic operation of such procedures with respect to the APS
is referred to hereinafter as an "Auction." If,  however,  the Trust should fail
to pay or duly provide for the full amount of any dividend on or the  redemption
price of the APS called for redemption,  the Applicable Rate for the APS will be
determined as set forth under "Description of  APS--Dividends--Determination  of
Dividend Rate."

      AUCTION  AGENT  AGREEMENT.  The Trust will enter  into an  agreement  (the
"Auction Agent  Agreement") with Bankers Trust (together with any successor bank
or trust  company or other entity  entering into a similar  agreement  with this
Trust,  the "Auction  Agent"),  which  provides,  among other  things,  that the
Auction Agent will follow the Auction  Procedures for the purpose of determining
the  Applicable  Rate  for  the  APS.  The  Trust  will  pay the  Auction  Agent
compensation for its services under the Auction Agent Agreement.

      The  Auction  Agent  will act as agent  for the Trust in  connection  with
Auctions.  In the absence of bad faith or  negligence  on its part,  the Auction
Agent will not be liable for any action taken,  suffered or omitted,  or for any
error of judgment made, by it in the performance of its duties under the Auction
Agent  Agreement,  and will not be liable for any error of judgment made in good
faith unless the Auction  Agent shall have been  negligent in  ascertaining  the
pertinent facts. Pursuant to the Auction Agent Agreement,  the Trust is required
to indemnify the Auction Agent for certain  losses and  liabilities  incurred by
the Auction Agent without negligence or bad faith on its part in connection with
the performance of its duties under such agreement.

      The Auction Agent may terminate the Auction Agent Agreement upon notice to
the Trust,  which termination may be no earlier than 60 days following  delivery
of such  notice.  If the  Auction  Agent  resigns,  the Trust  will use its best
efforts to enter into an agreement  with a successor  Auction  Agent  containing
substantially the same terms and conditions as the Auction Agent Agreement.  The
Trust may  terminate the Auction  Agent  Agreement,  provided that prior to such
termination  the Trust shall have entered  into such an  agreement  with respect
thereto with a successor Auction Agent.

      BROKER-DEALER AGREEMENTS. The Auctions require the participation of one or
more  broker-dealers.   The  Auction  Agent  will  enter  into  agreements  with
______________  and  may  enter  into  similar  agreements  (collectively,   the
"Broker-Dealer Agreements") with one or more other broker-dealers (collectively,
the "Broker-Dealers") selected by the Trust, which provide for the participation
of such Broker-Dealers in Auctions. A Broker-Dealer  Agreement may be terminated
by the Auction Agent or a Broker-Dealer on five days' notice to the other party,
provided that the Broker-Dealer Agreement with ___________ may not be terminated
without  the prior  written  consent  of the  Trust,  which  consent  may not be
unreasonably withheld.

      SECURITIES DEPOSITORY.  The Depository Trust Company initially will act as
the Securities  Depository for the Agent Members with respect to the APS. One or
more  registered  certificates  for  all of the  shares  of each  series  of APS
initially  will be registered  in the name of IBT, as nominee of the  Securities
Depository.  The  certificate  will  bear a  legend  to  the  effect  that  such


                                       22
<PAGE>

certificate is issued subject to the provisions restricting transfers of the APS
of the  series  to  which it  relates  contained  in the  Amended  By-Laws.  IBT
initially  will be the  holder of record of all  shares of APS,  and  Beneficial
Owners will not be entitled to receive certificates representing their ownership
interest in such shares. See Appendix D (Auction Procedures) to the Statement of
Additional  Information.  The Securities  Depository  will maintain lists of its
participants  and will maintain the positions  (ownership  interests) of the APS
held by each Agent Member,  whether as the Beneficial  Owner thereof for its own
account or as nominee for the  Beneficial  Owner  thereof.  Payments made by the
Trust to holders of APS will be duly made by making  payments  to the nominee of
the Securities Depository.

      AUCTION PROCEDURES.  The following is a brief summary of the procedures to
be used in  conducting  Auctions.  This summary is qualified by reference to the
Auction  procedures  set forth in  Appendix  C to the  Statement  of  Additional
Information.  The Settlement  Procedures to be used with respect to Auctions are
set forth in Appendix B to the Statement of Additional Information.

      AUCTION DATE; ADVANCE NOTICE OF ALLOCATION OF TAXABLE INCOME; INCLUSION OF
TAXABLE INCOME IN DIVIDENDS. An Auction to determine the Applicable Rate for the
APS offered  hereby for each  Dividend  Period for such  shares  (other than the
Initial  Dividend  Period  therefor)  will be held on the first Business Day (as
hereinafter  defined)  preceding  the first day of such Dividend  Period,  which
first day is also the Dividend  Payment Date for the preceding  Dividend  Period
(the date of each  Auction  being  referred  to herein  as an  "Auction  Date").
"Business  Day"  means a day on which the New York  Stock  Exchange  is open for
trading and which is not a  Saturday,  Sunday or other day on which banks in The
City of New York are  authorized or obligated by law to close.  Auctions for the
APS for Dividend Periods after the Initial Dividend Period normally will be held
every  ___  after the  preceding  Dividend  Payment  Date,  and each  subsequent
Dividend Period  normally will begin on the following  ________ (also a Dividend
Payment Date). The Auction Date and the first day of the related Dividend Period
(both of which must be Business Days) need not be consecutive calendar days. For
example,  in most cases,  if the ____ that normally would be an Auction Date for
the APS is not a Business  Day, then such Auction Date will be the preceding ___
and the  first  day of the  related  Dividend  Period  will  continue  to be the
following _____. See "Description of APS--Dividends" for information  concerning
the  circumstances  under which a Dividend Payment Date may fall on a date other
than the days specified above, which may affect the Auction Date.

      Except as noted  below,  whenever  the Trust  intends to  include  any net
capital  gains or other income  subject to regular  Federal  income taxes in any
dividend on the APS, the Trust will notify the Auction Agent of the amount to be
so included at least five  Business  Days prior to the Auction Date on which the
Applicable  Rate for such  dividend is to be  established.  Whenever the Auction
Agent  receives  such  notice  from  the  Trust,  in turn it  will  notify  each
Broker-Dealer,  who, on or prior to such Auction Date,  in  accordance  with its
Broker-Dealer Agreement, will notify its customers who are Beneficial Owners and
Potential  Beneficial Owners believed to be interested in submitting an Order in
the Auction to be held on such  Auction  Date.  The Trust also may include  such
income in a dividend  on the APS without  giving  advance  notice  thereof if it
increases the dividend by an additional amount calculated as if such income were
a Retroactive  Taxable  Allocation and the additional  amount were an Additional
Dividend;  provided  that  the  Trust  will  notify  the  Auction  Agent  of the
additional  amounts to be included in such  dividend at least five Business Days
prior  to the  applicable  Dividend  Payment  Date.  See  "Description  of APS--
Dividends--Additional Dividends."

      Orders by  Beneficial  Owners,  Potential  Beneficial  Owners,   Existing
Holders  and Potential Holders. On or prior to each Auction Date:

      (a) each Beneficial Owner may submit to its Broker-Dealer by telephone a:

            (i) Hold  Order--indicating  the number of outstanding  APS, if any,
      that such  Beneficial  Owner desires to continue to hold without regard to
      the Applicable Rate for the next Dividend Period for such shares;

            (ii)  Bid--indicating  the number of  outstanding  APS, if any, that
      such  Beneficial  Owner  desires to  continue to hold,  provided  that the
      Applicable  Rate for the next Dividend  Period for such shares is not less
      than the rate per annum then specified by such Beneficial Owner; and/or


                                       23
<PAGE>

            (iii) Sell  Order--indicating the number of outstanding APS, if any,
      that such Beneficial Owner offers to sell without regard to the Applicable
      Rate for the next Dividend Period for such shares; and

      (b)  Broker-Dealers  will contact  customers who are Potential  Beneficial
Owners of APS to determine  whether such Potential  Beneficial  Owners desire to
submit Bids  indicating the number of APS which they offer to purchase  provided
that the  Applicable  Rate for the next  Dividend  Period for such shares is not
less than the rates per annum specified in such Bids.

      The communication by a Beneficial Owner or Potential Beneficial Owner to a
Broker-Dealer  and the  communication by a Broker-Dealer,  whether or not acting
for its own  account,  to the  Auction  Agent of the  foregoing  information  is
hereinafter referred to as an "Order" and collectively as "Orders." A Beneficial
Owner  or  a  Potential   Beneficial   Owner  placing  an  Order,   including  a
Broker-Dealer  acting  in such  capacity  for its own  account,  is  hereinafter
referred to as a "Bidder" and  collectively as "Bidders." Any Order submitted by
a Beneficial Owner or a Potential Beneficial Owner to its Broker-Dealer, or by a
Broker-Dealer  to the Auction  Agent,  prior to the  Submission  Deadline on any
Auction Date shall be irrevocable.

      In an Auction,  a Beneficial  Owner may submit  different  types of Orders
with  respect  to APS then held by such  Beneficial  Owner,  as well as Bids for
additional APS. For information concerning the priority given to different types
of  Orders  placed  by  Beneficial   Owners,   see   "Submission  of  Orders  by
Broker-Dealers to Auction Agent" below.

      The Maximum Applicable Rate for the APS will be the Applicable  Percentage
of the  Reference  Rate.  The Auction Agent will round each  applicable  Maximum
Applicable Rate to the nearest  one-thousandth (0.001) of one percent per annum,
with any such number ending in five ten-thousandths of one percent being rounded
upwards to the nearest  one-thousandth (0.001) of one percent. The Auction Agent
will not round the applicable  Reference Rate as part of its  calculation of the
Maximum Applicable Rate.

      The Maximum  Applicable  Rate for the APS will depend on the credit rating
or ratings assigned to such shares. The Applicable Percentage will be determined
based on (i) the credit  rating  assigned on such date to such shares by S&P (or
if S&P shall not make such rating available,  the equivalent of such rating by a
Substitute Rating Agency), and (ii) whether the Trust has provided  notification
to the Auction Agent prior to the Auction  establishing  the Applicable Rate for
any dividend that net capital gains or other taxable  income will be included in
such dividend on the APS as follows:


                                    APPLICABLE
                                  PERCENTAGE OF        APPLICABLE
             S&P CREDIT RATINGS   REFERENCE RATE     PERCENTAGE OF
                                 -- NOTIFICATION     REFERENCE RATE
                                                     --NOTIFICATION

               AA- or higher           110%               150%
                  A- to A+             125%               160%
               BBB- to BBB+            150%               250%
                 Below BBB-            200%               275%


      There is no minimum Applicable Rate in respect of any Dividend Period.

      The Trust  will take all  reasonable  action  necessary  to enable  S&P to
provide a rating for the APS. If S&P shall not make such a rating available, the
Underwriter or its affiliates and successors, after consultation with the Trust,
will select  another Rating Agency (a  "Substitute  Rating  Agency") to act as a
Substitute Rating Agency.

      Any Bid by a Beneficial  Owner specifying a rate per annum higher than the
Maximum  Applicable  Rate  will be  treated  as a Sell  Order,  and any Bid by a
Potential  Beneficial  Owner specifying a rate per annum higher than the Maximum


                                       24
<PAGE>

Applicable  Rate  will  not be  considered.  See  "Determination  of  Sufficient
Clearing  Bids,  Winning  Bid Rate and  Applicable  Rate"  and  "Acceptance  and
Rejection of Submitted Bids and Submitted Sell Orders and Allocation of Shares."

      Neither  the  Trust  nor  the  Auction  Agent  will be  responsible  for a
Broker-Dealer's  failure to comply with the foregoing.  A Broker-Dealer also may
hold APS in its own account as a  Beneficial  Owner.  A  Broker-Dealer  thus may
submit  Orders  to the  Auction  Agent  as a  Beneficial  Owner  or a  Potential
Beneficial  Owner and therefore  participate in an Auction as an Existing Holder
or Potential Holder on behalf of both itself and its customers. Any Order placed
with the Auction Agent by a Broker-Dealer  as or on behalf of a Beneficial Owner
or a Potential  Beneficial  Owner will be treated in the same manner as an Order
placed with a  Broker-Dealer  by a  Beneficial  Owner or a Potential  Beneficial
Owner. Similarly,  any failure by a Broker-Dealer to submit to the Auction Agent
an Order in respect of any APS held by it or its  customers  who are  Beneficial
Owners will be treated in the same  manner as a  Beneficial  Owner's  failure to
submit to its  Broker-Dealer an Order in respect of APS held by it, as described
in the next paragraph. Inasmuch as a Broker-Dealer participates in an Auction as
an Existing  Holder or a Potential  Holder only to represent  the interests of a
Beneficial Owner or Potential  Beneficial Owner,  whether it be its customers or
itself,  all discussion  herein  relating to the  consequences of an Auction for
Existing Holders and Potential Holders also applies to the underlying beneficial
ownership interests represented thereby. For information concerning the priority
given to different types of Orders placed by Existing  Holders,  see "Submission
of Orders by  Broker-Dealers  to Auction  Agent."  Each  purchase  or sale in an
Auction will be settled on the Business Day next  succeeding the Auction Date at
a price per share equal to $25,000. See "Notification of Results; Settlement."

      If one or more Orders covering in the aggregate all of the outstanding APS
held by a Beneficial  Owner are not  submitted to the Auction Agent prior to the
Submission  Deadline,  either  because a  Broker-Dealer  failed to contact  such
Beneficial Owner or otherwise, the Auction Agent shall deem a Hold Order (in the
case of an Auction  relating to a Dividend Period which is not Special  Dividend
Period)  and a Sell  Order  (in the case of an  Auction  relating  to a  Special
Dividend  Period)  to have been  submitted  on behalf of such  Beneficial  Owner
covering the number of outstanding the APS held by such Beneficial Owner and not
subject to Orders submitted to the Auction Agent.

      If all of the  outstanding  APS are subject to Submitted Hold Orders,  the
Dividend  Period next  succeeding  the Auction  automatically  shall be the same
length as the immediately preceding Dividend Period, and the Applicable Rate for
the next Dividend  Period for all the APS will be 40% of the  Reference  Rate on
the  date  of the  applicable  Auction  (or 60% of such  rate if the  Trust  has
provided notification to the Auction Agent prior to the Auction establishing the
Applicable  Rate for any dividend that net capital gains or other taxable income
will be included in such dividend on the APS).

      For the  purposes  of an  Auction,  the APS for which the Trust shall have
given notice of redemption and deposited  moneys therefor with the Auction Agent
in trust or  segregated  in an account  at the  Trust's  custodian  bank for the
benefit  of the  Auction  Agent,  as  set  forth  under  "Description  of  APS--
Redemption,"  will not be considered as outstanding  and will not be included in
such Auction.  Pursuant to the Amended  By-Laws of the Trust,  the Trust will be
prohibited from reissuing and its affiliates  (other than the Underwriter)  will
be  prohibited  from  transferring  (other  than to the  Trust) any APS they may
acquire.  Neither  the Trust nor any  affiliate  of the  Trust  (other  than the
Underwriter) may submit an Order in any Auction, except that an affiliate of the
Trust that is a Broker-Dealer may submit an Order.

      SUBMISSION OF ORDERS BY  BROKER-DEALERS  TO AUCTION  AGENT.  Prior to 1:00
p.m.,  New York City  time,  on each  Auction  Date,  or such  other time on the
Auction  Date  as may  be  specified  by  the  Auction  Agent  (the  "Submission
Deadline"),  each  Broker-Dealer will submit to the Auction Agent in writing all
Orders  obtained by it for the Auction to be  conducted  on such  Auction  Date,
designating  itself  (unless  otherwise  permitted by the Trust) as the Existing
Holder or  Potential  Holder in respect of the APS subject to such  Orders.  Any
Order  submitted by a Beneficial  Owner or a Potential  Beneficial  Owner to its
Broker-Dealer,  or by a  Broker-Dealer  to  the  Auction  Agent,  prior  to  the
Submission Deadline on any Auction Date, shall be irrevocable.

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


                                       25
<PAGE>

more Orders of an Existing  Holder are  submitted to the Auction  Agent and such
Orders cover in the aggregate more than the number of outstanding  shares of APS
held by such  Existing  Holder,  such  Orders  will be  considered  valid in the
following order of priority:

      (i) any Hold Order will be considered valid up to and including the number
of outstanding APS held by such Existing Holder,  provided that if more than one
Hold Order is submitted by such Existing Holder and the number of APS subject to
such Hold Orders  exceeds the number of  outstanding  APS held by such  Existing
Holder,  the number of APS  subject to each of such Hold  Orders will be reduced
pro rata so that such Hold  Orders,  in the  aggregate,  will cover  exactly the
number of outstanding APS held by such Existing Holder;

      (ii) any Bids will be considered  valid,  in the ascending  order of their
respective  rates per annum if more than one Bid is submitted  by such  Existing
Holder,  up to and including the excess of the number of outstanding APS held by
such  Existing  Holder  over the number of  outstanding  APS subject to any Hold
Order  referred  to in clause (i) above (and if more than one Bid  submitted  by
such Existing  Holder  specifies the same rate per annum and together they cover
more than the  remaining  number of shares that can be the subject of valid Bids
after  application  of clause  (i) above and of the  foregoing  portion  of this
clause (ii) to any Bid or Bids  specifying a lower rate or rates per annum,  the
number of shares  subject to each of such Bids will be reduced  pro rata so that
such Bids, in the aggregate,  cover exactly such remaining number of outstanding
shares); and the number of outstanding shares, if any, subject to Bids not valid
under this  clause  (ii) shall be treated as the subject of a Bid by a Potential
Holder; and

      (iii) any Sell  Order will be  considered  valid up to and  including  the
excess of the number of  outstanding  APS held by such Existing  Holder over the
sum of the number of APS subject to Hold Orders  referred to in clause (i) above
and the number of APS subject to valid Bids by such Existing  Holder referred to
in clause (ii) above; provided that, if more than one Sell Order is submitted by
any Existing Holder and the number of APS subject to such Sell Orders is greater
than such excess,  the number of APS subject to each of such Sell Orders will be
reduced pro rata so that such Sell Orders, in the aggregate,  will cover exactly
the number of APS equal to such excess.

      If more than one Bid of any Potential  Holder is submitted in any Auction,
each Bid  submitted in such  Auction will be  considered a separate Bid with the
rate per annum and number of APS therein specified.

      DETERMINATION OF SUFFICIENT CLEARING BIDS, WINNING BID RATE AND APPLICABLE
RATE.  Not earlier than the  Submission  Deadline for each Auction,  the Auction
Agent  will  assemble  all Orders  submitted  or deemed  submitted  to it by the
Broker-Dealers  (each such "Hold  Order,"  "Bid" or "Sell Order" as submitted or
deemed  submitted  by  a  Broker-Dealer  hereinafter  being  referred  to  as  a
"Submitted  Hold Order," a "Submitted  Bid" or a "Submitted  Sell Order," as the
case may be, or as a  "Submitted  Order") and will  determine  the excess of the
number  of  outstanding  APS over the  number  of  outstanding  APS  subject  to
Submitted Hold Orders (such excess being referred to as the "Available APS") and
whether  Sufficient  Clearing  Bids have been made in such  Auction.  Sufficient
Clearing Bids will have been made if the number of outstanding  APS that are the
subject of Submitted  Bids of Potential  Holders with rates per annum not higher
than the Maximum  Applicable  Rate  equals or exceeds the number of  outstanding
shares that are the subject of Submitted  Sell Orders  (including  the number of
shares  subject to Bids of Existing  Holders  specifying  rates per annum higher
than the Maximum  Applicable Rate). If Sufficient  Clearing Bids have been made,
the Auction  Agent will  determine  the lowest rate per annum  specified  in the
Submitted  Bids (the  "Winning  Bid Rate")  which would  result in the number of
shares subject to Submitted Bids  specifying such rate per annum or a lower rate
per annum being at least equal to the Available APS. If Sufficient Clearing Bids
have been made,  the Winning Bid Rate will be the  Applicable  Rate for the next
Dividend Period for the APS then outstanding.  If Sufficient  Clearing Bids have
not been made  (other  than  because  all  outstanding  APS are the  subject  of
Submitted  Hold  Orders),   the  Dividend  Period  next  following  the  Auction
automatically  will be a 7-Day Dividend Period, and the Applicable Rate for such
Dividend Period will be equal to the Maximum Applicable Rate.

      If  Sufficient  Clearing Bids have not been made,  Beneficial  Owners that
have  Submitted Sell Orders will not be able to sell in the Auction all, and may
not be able to sell any,  the APS subject to such  Submitted  Sell  Orders.  See
"Acceptance  and  Rejection  of  Submitted  Bids and  Submitted  Sell Orders and
Allocation of Shares." Thus, under some circumstances, Beneficial Owners may not
have liquidity of investment.

      ACCEPTANCE  AND REJECTION OF SUBMITTED  BIDS AND SUBMITTED SELL ORDERS AND
ALLOCATION OF SHARES. Based on the determinations described under "Determination


                                       26
<PAGE>

of Sufficient  Clearing Bids,  Winning Bid Rate and Applicable Rate" and subject
to the  discretion of the Auction Agent to round as described  below,  Submitted
Bids and  Submitted  Sell  Orders  will be  accepted or rejected in the order of
priority  set forth in the  Auction  Procedures  with the result  that  Existing
Holders and Potential Holders of APS will sell, continue to hold and/or purchase
APS as set forth  below.  Existing  Holders  that  submit or are  deemed to have
submitted Hold Orders will continue to hold the APS subject to such Hold Orders.

      If Sufficient Clearing Bids have been made:

            (a) each Existing  Holder that placed a Submitted  Bid  specifying a
      rate per annum higher than the Winning Bid Rate or a Submitted  Sell Order
      will sell the  outstanding  APS subject to such Submitted Bid or Submitted
      Sell Order;

            (b) each Existing  Holder that placed a Submitted  Bid  specifying a
      rate per annum lower than the  Winning Bid Rate will  continue to hold the
      outstanding APS subject to such Submitted Bid;

            (c) each  Potential  Holder that placed a Submitted Bid specifying a
      rate per annum lower than the Winning Bid Rate will purchase the number of
      APS subject to such Submitted Bid;

            (d) each Existing  Holder that placed a Submitted  Bid  specifying a
      rate per annum  equal to the  Winning  Bid Rate will  continue to hold the
      outstanding  shares of APS  subject  to such  Submitted  Bids,  unless the
      number of  outstanding  APS subject to all such Submitted Bids of Existing
      Holders is greater than the excess of the Available APS over the number of
      APS  accounted  for in  clauses  (b) and (c)  above,  in which  event each
      Existing  Holder  with  such  a  Submitted  Bid  will  sell  a  number  of
      outstanding  APS  determined  on a pro rata  basis  based on the number of
      outstanding  APS  subject  to all  such  Submitted  Bids of such  Existing
      Holders; and

            (e) each  Potential  Holder that placed a Submitted Bid specifying a
      rate per annum equal to the Winning Bid Rate will  purchase any  Available
      APS not  accounted for in clause (b), (c) or (d) above on a pro rata basis
      based on the APS subject to all such Submitted Bids of Potential Holders.

      If  Sufficient  Clearing  Bids have not been made (other than  because all
outstanding APS are the subject of Submitted Hold Orders):

            (a) each Existing  Holder that placed a Submitted  Bid  specifying a
      rate per annum  equal to or lower than the  Maximum  Applicable  Rate will
      continue to hold the outstanding APS subject to such Submitted Bid;

            (b) each  Potential  Holder that placed a Submitted Bid specifying a
      rate per annum  equal to or lower than the  Maximum  Applicable  Rate will
      purchase the number of APS subject to such Submitted Bid; and

            (c) each Existing  Holder that placed a Submitted  Bid  specifying a
      rate per annum higher than the Maximum Applicable Rate or a Submitted Sell
      Order will sell a number of outstanding APS determined on a pro rata basis
      based  on the  outstanding  APS  subject  to all such  Submitted  Bids and
      Submitted Sell Orders. If as a result of the Auction Procedures  described
      above any Existing  Holder  would be entitled or required to sell,  or any
      Potential Holder would be entitled or required to purchase,  a fraction of
      APS,  the Auction  Agent,  in such manner as, in its sole  discretion,  it
      shall  determine,  will  round up or down the  number of APS being sold or
      purchased  on such  Auction  Date so that each share sold or  purchased by
      each  Existing  Holder or  Potential  Holder  will be a whole APS.  If any
      Potential  Holder  would be entitled  or required to purchase  less than a
      whole APS, the Auction Agent,  in such manner as, in its sole  discretion,
      it shall determine, will allocate APS for purchase among Potential Holders
      so that only whole APS are purchased by any such Potential Holder, even if
      such  allocation  results  in one or more of such  Potential  Holders  not
      purchasing any APS.


                                       27
<PAGE>

      NOTIFICATION  OF RESULTS;  SETTLEMENT.  The Auction Agent will advise each
Broker-Dealer  who submitted a Bid or Sell Order in an Auction  whether such Bid
or Sell Order was accepted or rejected in whole or in part and of the Applicable
Rate  for  the  next  Dividend  Period  for  the  related  APS by  telephone  at
approximately  3:00  p.m.,  New York City  time,  on the  Auction  Date for such
Auction.  Each such  Broker-Dealer  that submitted an Order for the account of a
customer  then will  advise  such  customer  whether  such Bid or Sell Order was
accepted  or  rejected,  will  confirm  purchases  and sales with each  customer
purchasing  or  selling  APS as a result of the  Auction  and will  advise  each
customer  purchasing or selling APS to give  instructions to its Agent Member of
the  Securities  Depository to pay the purchase  price against  delivery of such
shares or to deliver such shares against payment  therefor as appropriate.  If a
customer  selling APS as a result of an Auction shall fail to instruct its Agent
Member to deliver such shares,  the Broker-Dealer that submitted such customer's
Bid or Sell Order will instruct such Agent Member to deliver such shares against
payment therefor.  Each  Broker-Dealer that submitted a Hold Order in an Auction
on behalf of a customer  also will advise such customer of the  Applicable  Rate
for the next  Dividend  Period for the APS.  The Auction  Agent will record each
transfer of APS on the record book of Existing  Holders to be  maintained by the
Auction Agent.

      In accordance with the Securities  Depository's normal procedures,  on the
day after each Auction Date, the  transactions  described above will be executed
through the  Securities  Depository,  and the accounts of the  respective  Agent
Members at the Securities  Depository  will be debited and credited as necessary
to  effect  the  purchases  and  sales  of APS as  determined  in such  Auction.
Purchasers  will make payment  through their Agent Members in same-day  funds to
the Securities  Depository  against  delivery  through their Agent Members;  the
Securities   Depository   will  make  payment  in  accordance  with  its  normal
procedures,  which now provide for payment in same-day  funds. If the procedures
of the Securities  Depository  applicable to APS shall be changed to provide for
payment in next-day  funds,  then  purchasers may be required to make payment in
next-day funds. If the  certificates  for the APS are not held by the Securities
Depository or its nominee, payment will be made in same-day funds to the Auction
Agent against delivery of such certificates.

      If any  Existing  Holder  selling APS in an Auction  fails to deliver such
shares,  the  Broker-Dealer of any person that was to have purchased APS in such
Auction  may  deliver to such person a number of whole APS that is less than the
number of shares that  otherwise  was to be purchased  by such  person.  In such
event,  the  number  of  APS to be so  delivered  will  be  determined  by  such
Broker-Dealer.  Delivery of such lesser  number of shares will  constitute  good
delivery.  Each Broker-Dealer Agreement also will provide that neither the Trust
nor the Auction Agent will have  responsibility or liability with respect to the
failure of a Potential  Beneficial  Owner,  Beneficial Owner or their respective
Agent  Members to deliver APS or to pay for APS purchased or sold pursuant to an
Auction or otherwise.

BROKER-DEALERS

      The Auction Agent after each Auction will pay a service  charge from funds
provided by the Trust to each  Broker-Dealer  on the basis of the purchase price
of APS placed by such Broker-Dealer at such Auction.  The service charge (i) for
any 7-Day  Dividend  Period  shall be payable at the annual rate of 0.25% of the
purchase price of the APS placed by such  Broker-Dealer  in any such Auction and
(ii) for any Special  Dividend  Period shall be determined by mutual  consent of
the Trust and any such Broker-Dealer or Broker-Dealers and shall be based upon a
selling  concession  that would be  applicable  to an  underwriting  of fixed or
variable rate  preferred  shares with a similar final  maturity or variable rate
dividend period,  respectively,  at the commencement of the Dividend Period with
respect to such  Auction.  For the purposes of the preceding  sentence,  the APS
will be placed by a  Broker-Dealer  if such  shares were (i) the subject of Hold
Orders deemed to have been made by Beneficial  Owners that were acquired by such
Beneficial  Owners  through  such  Broker-Dealer  or  (ii)  the  subject  of the
following  Orders  submitted  by such  Broker-Dealer:  (A) a Submitted  Bid of a
Beneficial  Owner that resulted in such Beneficial Owner continuing to hold such
shares as a result of the Auction, (B) a Submitted Bid of a Potential Beneficial
Owner that resulted in such Potential Beneficial Owner purchasing such shares as
a result of the Auction or (C) a Submitted Hold Order.

      The  Broker-Dealer  Agreements  provide  that a  Broker-Dealer  may submit
Orders  in  Auctions  for  its  own  account,  unless  the  Trust  notifies  all
Broker-Dealers  that they no longer may do so; provided that  Broker-Dealers may
continue to submit Hold Orders and Sell Orders.  If a  Broker-Dealer  submits an


                                       28
<PAGE>

Order for its own account in any Auction of APS, it may have knowledge of Orders
placed  through it in that Auction and  therefore  have an advantage  over other
Bidders,  but such Broker-Dealer would not have knowledge of Orders submitted by
other Broker-Dealers in that Auction.

      The  Broker-Dealers  may  maintain a secondary  trading  market in the APS
outside of Auctions;  however, they have no obligation to do so and there can be
no  assurance  that a secondary  market for the APS will  develop or, if it does
develop,  that it will  provide  holders  with a liquid  trading  market  (I.E.,
trading  will  depend on the  presence  of willing  buyers and  sellers  and the
trading  price is subject to variables to be determined at the time of the trade
by the Broker-Dealers).  The APS will not be registered on any stock exchange or
on any automated  quotation  system. An increase in the level of interest rates,
particularly  during any Long-Term Dividend Period,  likely will have an adverse
effect on the secondary  market price of the APS, and a selling  shareholder may
sell APS between Auctions at a price per share of less than $25,000.

DIVIDENDS

      GENERAL. The holders of the APS will be entitled to receive,  when, as and
if declared by the Board of Trustees,  out of funds legally available  therefor,
cumulative cash dividends on their shares,  at the Applicable Rate determined as
set forth below under "Determination of Dividend Rate," payable on the dates set
forth below.  Dividends on the APS so declared and payable  shall be paid (i) in
preference  to and in priority over any dividends so declared and payable on the
Common Shares, and (ii) to the extent permitted under the Code and to the extent
available,  out of net tax-exempt income earned on the Trust's  investments.  To
the extent  permitted under the Code,  dividends on APS, to the extent that they
are derived  from  Municipal  Obligations,  will be exempt from  Federal  income
taxes,  subject to possible  application  of the  alternative  minimum  tax. See
"Taxes."

      Dividends  on the APS will  accumulate  from the date on which  the  Trust
originally  issues the APS (the "Date of Original Issue") and will be payable on
the APS on the dates described  below.  Dividends on the APS with respect to the
Initial  Dividend Period shall be payable on the Initial  Dividend Payment Date.
Following  the  Initial  Dividend  Payment  Date,  dividends  on the APS will be
payable,  at the  option of the  Trust,  either  (i) with  respect  to any 7-Day
Dividend  Period and any Short Term Dividend  Period of 35 or fewer days, on the
day next  succeeding the last day thereof or (ii) with respect to any Short Term
Dividend  Period of more than 35 days and with respect to any Long Term Dividend
Period,  monthly on the first  Business Day of each  calendar  month during such
Short  Term  Dividend  Period or Long Term  Dividend  Period and on the day next
succeeding  the last day  thereof  (each such date  referred to in clause (i) or
(ii) being referred to herein as a "Normal Dividend Payment Date"),  except that
if such Normal Dividend Payment Date is not a Business Day, the Dividend Payment
Date  shall be the first  Business  Day next  succeeding  such  Normal  Dividend
Payment Date. Although any particular Dividend Payment Date may not occur on the
originally  scheduled date because of the exceptions  discussed  above, the next
succeeding Dividend Payment Date, subject to such exceptions,  will occur on the
next following  originally  scheduled date. If for any reason a Dividend Payment
Date cannot be fixed as described  above,  then the Board of Trustees  shall fix
the  Dividend  Payment  Date.  The  Board of  Trustees  by  resolution  prior to
authorization  of a  dividend  by the Board of  Trustees  may  change a Dividend
Payment Date if such change does not adversely affect the contract rights of the
holders of shares of APS set forth in the Charter.  The Initial Dividend Period,
7-Day Dividend Periods and Special  Dividend  Periods are hereinafter  sometimes
referred to as "Dividend  Periods."  Each  dividend  payment date  determined as
provided above is hereinafter referred to as a "Dividend Payment Date."

      Prior to each Dividend Payment Date, the Trust is required to deposit with
the Auction Agent  sufficient funds for the payment of declared  dividends.  The
Trust does not intend to establish any reserves for the payment of dividends.

      Each dividend  will be paid to the record holder of the APS,  which holder
is expected to be the nominee of the Securities Depository.  See "Description of
APS--The Auction--Securities  Depository." The Securities Depository will credit
the accounts of the Agent Members of the Existing Holders in accordance with the
Securities  Depository's normal procedures which provide for payment in same-day
funds. The Agent Member of an Existing Holder will be responsible for holding or
disbursing  such  payments  on the  applicable  Dividend  Payment  Date  to such


                                       29
<PAGE>

Existing  Holder in accordance with the  instructions  of such Existing  Holder.
Dividends  in arrears for any past  Dividend  Period may be declared and paid at
any time, without reference to any regular Dividend Payment Date, to the nominee
of the Securities  Depository.  Any dividend payment made on the APS first shall
be credited against the earliest declared but unpaid dividends  accumulated with
respect to such shares.

      Holders of the APS will not be entitled to any dividends,  whether payable
in cash,  property or stock,  in excess of full cumulative  dividends  except as
described under  "Additional  Dividends" and "Non-Payment  Period;  Late Charge"
below.  No  interest  will be  payable in  respect  of any  dividend  payment or
payments on the APS which may be in arrears.

      The amount of cash dividends per share of APS payable (if declared) on the
Initial  Dividend  Payment Date,  each 7-Day  Dividend  Period and each Dividend
Payment Date of each Short Term Dividend Period shall be computed by multiplying
the  Applicable  Rate for such Dividend  Period by a fraction,  the numerator of
which will be the number of days in such  Dividend  Period or part  thereof that
such share was  outstanding and for which dividends are payable on such Dividend
Payment Date and the denominator of which will be 365, multiplying the amount so
obtained by $25,000,  and rounding  the amount so obtained to the nearest  cent.
During any Long Term Dividend Period,  the amount of cash dividends per share of
APS payable (if  declared)  on any  Dividend  Payment  Date shall be computed by
multiplying  the  Applicable  Rate for such Dividend  Period by a fraction,  the
numerator  of which  will be such  number of days in such part of such  Dividend
Period that such share was  outstanding  and for which  dividends are payable on
such Dividend Payment Date and the denominator of which will be 360, multiplying
the amount so obtained by $25,000,  and  rounding  the amount so obtained to the
nearest cent.

      NOTIFICATION OF DIVIDEND PERIOD. With respect to each Dividend Period that
is a Special  Dividend  Period,  the Trust, at its sole option and to the extent
permitted  by law,  by  telephonic  and written  notice (a "Request  for Special
Dividend  Period") to the Auction Agent and to each  Broker-Dealer,  may request
that the next  succeeding  Dividend  Period for the APS will be a number of days
(other than seven), evenly divisible by seven, and not fewer than seven nor more
than 364 in the case of a Short Term  Dividend  Period or one whole year or more
but not  greater  than five  years in the case of a Long Term  Dividend  Period,
specified  in such  notice,  provided  that the Trust may not give a Request for
Special  Dividend  Period (and any such request  shall be null and void) unless,
for any Auction  occurring after the initial Auction,  Sufficient  Clearing Bids
were made in the last occurring  Auction and unless full  cumulative  dividends,
any  amounts  due with  respect to  redemptions,  and any  Additional  Dividends
payable  prior to such date have been paid in full.  Such  Request  for  Special
Dividend Period, in the case of a Short Term Dividend Period,  shall be given on
or prior to the second  Business Day but not more than seven Business Days prior
to an Auction Date for the APS and, in the case of a Long Term Dividend  Period,
shall be given on or prior to the second  Business Day but not more than 28 days
prior to an Auction Date for the APS.  Upon  receiving  such Request for Special
Dividend Period, the Broker-Dealers  jointly shall determine whether,  given the
factors  set forth  below,  it is  advisable  that the  Trust  issue a Notice of
Special  Dividend Period as  contemplated  by such Request for Special  Dividend
Period and the Optional Redemption Price of the APS during such Special Dividend
Period and the Specific  Redemption  Provisions and shall give the Trust and the
Auction Agent written notice (a "Response")  of such  determination  by no later
than the  second  Business  Day  prior to such  Auction  Date.  In  making  such
determination,  the  Broker-Dealers  will consider (i) existing  short-term  and
long-term market rates and indices of such short-term and long-term rates,  (ii)
existing market supply and demand for short-term and long-term securities, (iii)
existing yield curves for short-term and long-term securities  comparable to the
APS, (iv) industry and  financial  conditions  which may affect the APS, (v) the
investment  objective  of the Trust and (vi) the  Dividend  Periods and dividend
rates at which current and potential  beneficial holders of the APS would remain
or become beneficial holders.

      If the  Broker-Dealers  shall not give the Trust and the  Auction  Agent a
Response by such second  Business Day or if the  Response  states that given the
factors  set forth  above it is not  advisable  that the Trust  give a Notice of
Special  Dividend Period for the APS, the Trust may not give a Notice of Special
Dividend Period in respect of such Request for Special Dividend  Period.  In the
event the Response  indicates  that it is advisable that the Trust give a Notice
of Special  Dividend  Period for the APS, the Trust, by no later than the second
Business Day prior to such Auction Date, may give a notice (a "Notice of Special
Dividend  Period") to the Auction  Agent,  the  Securities  Depository  and each
Broker-Dealer,  which  notice  will  specify  (i) the  duration  of the  Special


                                       30
<PAGE>

Dividend Period,  (ii) the Optional Redemption Price as specified in the related
Response and (iii) the Specific Redemption  Provisions,  if any, as specified in
the  related  Response.  The Trust also shall  provide a copy of such  Notice of
Special  Dividend  Period to S&P.  The Trust  shall not give a Notice of Special
Dividend Period,  and, if such Notice of Special Dividend Period shall have been
given  already,  shall give  telephonic  and written notice of its revocation (a
"Notice of  Revocation")  to the  Auction  Agent,  each  Broker-Dealer,  and the
Securities  Depository  on or prior to the  Business  Day prior to the  relevant
Auction Date if (x) either the 1940 Act APS Asset  Coverage is not  satisfied or
the  Trust  shall  fail to  maintain  S&P  Eligible  Assets  with  an  aggregate
Discounted Value at least equal to the APS Basic Maintenance  Amount, on each of
the two  Valuation  Dates  immediately  preceding  the Business Day prior to the
relevant  Auction Date on an actual basis and on a pro forma basis giving effect
to the proposed Special Dividend Period (using as a pro forma dividend rate with
respect  to  such  Special   Dividend   Period  the  dividend   rate  which  the
Broker-Dealers  shall  advise  the  Trust  is an  approximately  equal  rate for
securities  similar to the APS with an equal  dividend  period),  (y) sufficient
funds  for the  payment  of  dividends  payable  on the  immediately  succeeding
Dividend Payment Date have not been irrevocably deposited with the Auction Agent
by the close of business on the third Business Day preceding the related Auction
Date  or  (z)  the   Broker-Dealers   jointly  advise  the  Trust  that,   after
consideration  of the  factors  listed  above,  they have  concluded  that it is
advisable to give a Notice of Revocation. The Trust also shall provide a copy of
such  Notice of  Revocation  to S&P.  If the Trust is  prohibited  from giving a
Notice of  Special  Dividend  Period as a result of the  factors  enumerated  in
clause (x), (y) or (z) above or if the Trust gives a Notice of  Revocation  with
respect to a Notice of Special  Dividend  Period,  the next succeeding  Dividend
Period for that series will be a 7-Day  Dividend  Period.  In  addition,  in the
event Sufficient  Clearing Bids are not made in any Auction or an Auction is not
held  for any  reason,  the  next  succeeding  Dividend  Period  will be a 7-Day
Dividend  Period,  and the Trust may not again give a Notice of Special Dividend
Period (and any such attempted  notice shall be null and void) until  Sufficient
Clearing  Bids have been made in an Auction  with  respect  to a 7-Day  Dividend
Period.

      DETERMINATION  OF DIVIDEND  RATE.  The dividend rate on the APS during the
period  from  and  including  the  Date  of  Original  Issue  for the APS to but
excluding the Initial Dividend  Payment Date for the APS (the "Initial  Dividend
Period")  will be the rate per annum set forth on the inside  cover page hereof.
Commencing on the Initial Dividend Payment Date for the APS, the Applicable Rate
on the APS for each Subsequent Dividend Period, which Subsequent Dividend Period
shall be a period commencing on and including a Dividend Payment Date and ending
on and including  the calendar day prior to the next  Dividend  Payment Date (or
last  Dividend  Payment  Date in a  Dividend  Period  if there is more  than one
Dividend  Payment Date),  shall be equal to the rate per annum that results from
the  Auction  with  respect to such  Subsequent  Dividend  Period.  The  Initial
Dividend Period and Subsequent Dividend Period for the APS is referred to herein
as a "Dividend  Period." Cash  dividends  shall be calculated as set forth above
under "Dividends--General."

      NON-PAYMENT PERIOD; LATE CHARGE. A Non-Payment Period will commence if the
Trust  fails to (i)  declare,  prior  to the  close of  business  on the  second
Business Day  preceding  any Dividend  Payment  Date,  for payment on or (to the
extent  permitted as described  below)  within  three  Business  Days after such
Dividend  Payment Date to the persons who held such shares as of 12:00 noon, New
York City time, on the Business Day preceding  such Dividend  Payment Date,  the
full amount of any dividend on the APS payable on such Dividend  Payment Date or
(ii) deposit, irrevocably in trust, in same-day funds, with the Auction Agent by
12:00 noon,  New York 40 City time,  (A) on such Dividend  Payment Date the full
amount  of any cash  dividend  on such  shares  (if  declared)  payable  on such
Dividend  Payment  Date or (B) on any  redemption  date for the APS  called  for
redemption, the Mandatory Redemption Price per share of such APS or, in the case
of an  optional  redemption,  the  Optional  Redemption  Price per  share.  Such
Non-Payment  Period will consist of the period  commencing  on and including the
aforementioned Dividend Payment Date or redemption date, as the case may be, and
ending on and including the Business Day on which,  by 12:00 noon, New York City
time, all unpaid cash dividends and unpaid  redemption prices shall have been so
deposited or otherwise shall have been made available to the applicable  holders
in same-day funds,  provided that a Non-Payment  Period for the APS will not end
unless the Trust  shall have given at least five days' but no more than 30 days'
written  notice of such  deposit  or  availability  to the  Auction  Agent,  the
Securities Depository and all holders of the APS of such series. Notwithstanding
the  foregoing,  the failure by the Trust to deposit  funds as  provided  for by
clauses (ii) (A) or (ii) (B) above within three Business Days after any Dividend


                                       31
<PAGE>

Payment Date or redemption  date, as the case may be, in each case to the extent
contemplated below, shall not constitute a "Non-Payment  Period." The Applicable
Rate for each  Dividend  Period for the APS of any series,  commencing  during a
Non-Payment  Period,  will be equal to the  Non-Payment  Period  Rate;  and each
Dividend  Period  commencing  after the first day of, and during,  a Non-Payment
Period  shall be a 7-Day  Dividend  Period.  Any  dividend on the APS due on any
Dividend Payment Date for such shares (if, prior to the close of business on the
second Business Day preceding such Dividend Payment Date, the Trust has declared
such dividend payable on such Dividend Payment Date to the persons who held such
shares as of 12:00 noon,  New York City time, on the Business Day preceding such
Dividend  Payment Date) or redemption price with respect to such shares not paid
to such  persons  when due may be paid to such persons in the same form of funds
by 12:00 noon, New York City time, on any of the first three Business Days after
such Dividend  Payment Date or due date, as the case may be,  provided that such
amount is accompanied by a late charge calculated for such period of non-payment
at the Non-Payment  Period Rate applied to the amount of such non-payment  based
on the actual number of days  comprising such period divided by 365. In the case
of a willful  failure of the Trust to pay a dividend on a Dividend  Payment Date
or to redeem any APS on the date set for such redemption, the preceding sentence
shall not apply  and the  Applicable  Rate for the  Dividend  Period  commencing
during  the  Non-Payment  Period  resulting  from  such  failure  shall  be  the
Non-Payment Period Rate. For the purposes of the foregoing,  payment to a person
in same-day funds on any Business Day at any time will be considered  equivalent
to payment to that person in New York  Clearing  House  (next-day)  funds at the
same time on the preceding  Business Day, and any payment made after 12:00 noon,
New York City time,  on any Business Day shall be  considered  to have been made
instead in the same form of funds and to the same person before 12:00 noon,  New
York City time, on the next Business Day. The Non-Payment  Period Rate initially
will be 200% of the applicable Reference Rate (or 275% of such rate if the Trust
has provided notification to the Auction Agent prior to the Auction establishing
the  Applicable  Rate for any dividend  that net capital  gains or other taxable
income will be included in such dividend on the APS), provided that the Board of
Trustees  of the Trust  shall have the  authority  to adjust,  modify,  alter or
change  from time to time the  initial  Non-Payment  Period Rate if the Board of
Trustees of the Trust  determines  and S&P (or any  Substitute  Rating Agency in
lieu of S&P in the event such party shall not rate the APS) advises the Trust in
writing  that such  adjustment,  modification,  alteration  or  change  will not
adversely affect its then-current rating on the APS.

      RESTRICTIONS  ON  DIVIDENDS  AND OTHER  PAYMENTS.  Under the 1940 Act, the
Trust may not declare dividends or make other  distributions on Common Shares or
purchase  any such shares if, at the time of the  declaration,  distribution  or
purchase,  as applicable (and after giving effect  thereto),  asset coverage (as
defined in the 1940 Act) with respect to the  outstanding APS would be less than
200% (or such other  percentage  as in the future may be required  by law).  The
Trust estimates that, based on the composition of its portfolio at _____,  1999,
asset coverage with respect to the APS would be approximately  ____% immediately
after the issuance of the APS offered hereby.  Under the Code, the Trust,  among
other things,  must  distribute at least 90% of its investment  company  taxable
income each year in order to maintain its  qualification  for tax treatment as a
regulated   investment   company.   The  foregoing   limitations  on  dividends,
distributions  and  purchases  in certain  circumstances  may impair the Trust's
ability to maintain such qualification. See "Taxes."

      Upon any failure to pay  dividends  on the APS for two years or more,  the
holders of the APS will acquire certain  additional  voting rights.  See "Voting
Rights" below.  Such rights shall be the exclusive  remedy of the holders of APS
upon any failure to pay dividends on shares of the Trust.

      For so long as any APS are outstanding, the Trust will not declare, pay or
set apart for payment any dividend or other distribution  (other than a dividend
or distribution  paid in shares of, or options,  warrants or rights to subscribe
for or purchase, Common Shares or other stock, if any, ranking junior to the APS
as to dividends or upon  liquidation)  in respect of Common  Shares or any other
stock of the Trust ranking junior to or on a parity with the APS as to dividends
or upon  liquidation,  or call for  redemption,  redeem,  purchase or  otherwise
acquire for  consideration  any shares of Common Shares or any other such junior
stock  (except by  conversion  into or exchange  for stock of the Trust  ranking
junior to APS as to  dividends  and upon  liquidation)  or any such parity stock
(except by conversion  into or exchange for stock of the Trust ranking junior to
or on a  parity  with APS as to  dividends  and upon  liquidation),  unless  (A)
immediately  after such  transaction,  the Trust would have S&P Eligible  Assets
with an  aggregate  Discounted  Value  equal to or  greater  than the APS  Basic
Maintenance Amount, and the 1940 Act APS Asset Coverage (see "Asset Maintenance"
and "Redemption" below) would be satisfied, (B) full cumulative dividends on the
APS due on or prior to the date of the  transaction  have been declared and paid
or shall  have  been  declared  and  sufficient  funds for the  payment  thereof
deposited with the Auction Agent,  (C) any  Additional  Dividend  required to be
paid on or before the date of such  declaration or payment has been paid and (D)
the Trust has  redeemed  the full  number of APS  required to be redeemed by any
provision for mandatory redemption contained in the Amended By-Laws.

      ADDITIONAL DIVIDENDS. If the Trust retroactively allocates any net capital
gains or other income subject to regular Federal income taxes to the APS without


                                       32
<PAGE>

having given  advance  notice  thereof to the Auction  Agent as described  above
under  "The  Auction--Auction  Date;  Advance  Notice of  Allocation  of Taxable
Income;  Inclusion of Taxable Income in  Dividends,"  which may only happen when
such allocation is made as a result of the redemption of all or a portion of the
outstanding  APS or the  liquidation of the Trust (the amount of such allocation
referred to herein as a "Retroactive Taxable Allocation"),  the Trust, within 90
days (and generally within 60 days) after the end of the Trust's fiscal year for
which a Retroactive  Taxable  Allocation is made, will provide notice thereof to
the Auction Agent and to each holder of shares  (initially IBT as nominee of the
Securities  Depository)  during such fiscal year at such holder's address as the
same appears or last appeared on the stock books of the Trust. The Trust, within
30 days after such notice is given to the Auction Agent, will pay to the Auction
Agent  (who then  will  distribute  to such  holders  of the APS),  out of funds
legally available therefor, an amount equal to the aggregate Additional Dividend
(as defined below) with respect to all Retroactive  Taxable  Allocations made to
such holders during the fiscal year in question. See "Taxes."

      An  "Additional  Dividend"  means payment to a present or former holder of
the APS of an amount which,  when taken  together  with the aggregate  amount of
Retroactive  Taxable  Allocations made to such holder with respect to the fiscal
year in question,  would cause such holder's dividends in dollars (after Federal
income tax  consequences)  from the  aggregate of both the  Retroactive  Taxable
Allocations and the Additional  Dividend to be equal to the dollar amount of the
dividends  which  would have been  received  by such holder if the amount of the
aggregate  Retroactive  Taxable  Allocations  had been excludable from the gross
income of such holder.  Such Additional Dividend shall be calculated (i) without
consideration  being  given to the time value of money;  (ii)  assuming  that no
holder of APS is subject to the Federal  alternative minimum tax with respect to
dividends  received from the Trust;  and (iii)  assuming  that each  Retroactive
Taxable  Allocation  would be taxable in the hands of each  holder of APS at the
greater of: (a) the maximum marginal regular Federal  individual income tax rate
applicable  to  ordinary  income  or  capital  gains  depending  on the  taxable
character of the distribution (including any surtax); or (b) the maximum regular
Federal corporate income tax rate applicable to ordinary income or capital gains
depending on the taxable character of the distribution (disregarding in both (a)
and (b) the  effect  of any  state  and  local  taxes  and the  phase out of, or
provision limiting, personal exemptions,  itemized deductions, or the benefit of
lower tax  brackets).  Although the Trust  generally  intends to  designate  any
Additional  Dividend as an  exempt-interest  dividend to the extent permitted by
applicable law, it is possible that all or a portion of any Additional  Dividend
will  be  taxable  to  the  recipient  thereof.  See  "Taxes--Tax  Treatment  of
Additional Dividends." The Trust will not pay a further Additional Dividend with
respect to any taxable portion of an Additional Dividend.

      If the Trust does not give advance  notice of the amount of taxable income
to be included in a dividend on the APS in the  related  Auction,  as  described
above under "The Auction--Auction  Date; Advance Notice of Allocation of Taxable
Income;  Inclusion of Taxable Income in  Dividends,"  the Trust may include such
taxable  income in a dividend  on the APS if it  increases  the  dividend  by an
additional  amount  calculated  as if such  income  were a  Retroactive  Taxable
Allocation  and the additional  amount were an Additional  Dividend and notifies
the Auction Agent of such  inclusion at least five days prior to the  applicable
Dividend Payment Date.

ASSET MAINTENANCE

      The Trust will be  required  to satisfy  two  separate  asset  maintenance
requirements  under the terms of the Amended  By-Laws.  These  requirements  are
summarized below.

      1940 ACT APS ASSET COVERAGE.  The Trust will be required under the Amended
By-Laws to  maintain,  with  respect to the APS, as of the last  Business Day of
each month in which any APS are  outstanding,  asset  coverage  of at least 200%
with respect to senior  securities which are beneficial  interests in the Trust,
including  the APS  (or  such  other  asset  coverage  as in the  future  may be
specified  in or under the 1940 Act as the  minimum  asset  coverage  for senior
securities which are beneficial interests of a closed-end  investment company as
a  condition  of paying  dividends  on its  common  stock)  ("1940 Act APS Asset
Coverage").  If the Trust fails to maintain 1940 Act APS Asset Coverage and such
failure is not cured as of the last  Business  Day of the  following  month (the
"1940 Act Cure Date"),  the Trust will be required in certain  circumstances  to
redeem certain of the APS. See "Redemption" below.

      The 1940 Act APS Asset Coverage immediately  following the issuance of APS
offered  hereby  [AFTER  GIVING  EFFECT TO THE  DEDUCTION  OF THE SALES LOAD AND
OFFERING EXPENSES FOR THE APS] will be computed as follows:


                                       33
<PAGE>


Value of Trust assets less
liabilities not constituting senior

indebtedness plus liquidation value
of the shares of APS


      APS BASIC  MAINTENANCE  AMOUNT.  So long as the APS are  outstanding,  the
Trust will be required under the Amended By-Laws to maintain as of each Business
Day (a  "Valuation  Date") S&P  Eligible  Assets and having in the  aggregate  a
Discounted  Value at least  equal to the APS Basic  Maintenance  Amount.  If the
Trust fails to meet such  requirement  as of any Valuation Date and such failure
is not cured on or before the sixth  Business Day after such Valuation Date (the
"APS  Basic  Maintenance  Cure  Date"),  the Trust will be  required  in certain
circumstances  to redeem  certain of the APS.  Upon any failure to maintain  the
required  Discounted  Value,  the Trust  will use its best  efforts to alter the
composition of its portfolio to retain a Discounted  Value at least equal to the
APS Basic Maintenance Amount on or prior to the APS Basic Maintenance Cure Date.
See "Redemption."

      The APS Basic  Maintenance  Amount as of any Valuation  Date is defined as
the dollar  amount  equal to (i) the sum of (A) the product of the number of APS
outstanding  on such  Valuation  Date  multiplied  by the sum of $25,000 and any
applicable  redemption premium attributable to the designation of a Premium Call
Period;  (B) the aggregate  amount of cash  dividends  (whether or not earned or
declared)  that  will  have  accumulated  for each APS  outstanding  to (but not
including)  the end of the current  Dividend  Period that follows such Valuation
Date in the event the  then-current  Dividend Period will end within 49 calendar
days of such Valuation Date or through the 49th day after such Valuation Date in
the event the  then-current  Dividend  Period for the APS will not end within 49
calendar days of such Valuation Date; (C) in the event the then-current Dividend
Period will end within 49 calendar days of such  Valuation  Date,  the aggregate
amount of cash dividends that would  accumulate at the Maximum  Applicable  Rate
applicable to a Dividend Period of 28 or fewer days on any APS outstanding  from
the end of such Dividend  Period through the 49th day after such Valuation Date,
multiplied  by the S&P  Volatility  Factor  determined  from time to time by S&P
(except that if such Valuation Date occurs during a Non-Payment Period, the cash
dividend  for  purposes of  calculation  would  accumulate  at the  then-current
Non-Payment  Period Rate); (D) the amount of anticipated  Trust expenses for the
90 days subsequent to such Valuation Date  (including any premiums  payable with
respect to a Policy); (E) the amount of the Trust's Maximum Potential Additional
Dividend Liability as of such Valuation Date; and (F) any current liabilities as
of such Valuation Date to the extent not reflected in any of (i) (A) through (i)
(E) (including,  without  limitation,  and immediately upon  determination,  any
amounts due and  payable by the Trust  pursuant to  repurchase  agreements,  any
amounts payable for Municipal  Obligations  purchased as of such Valuation Date)
less (ii) either (A) the Discounted  Value of any Trust assets,  or (B) the face
value of any of the Trust's assets if such assets mature prior to or on the date
of  redemption  of the APS or payment of a liability  and are either  securities
issued or guaranteed by the United States Government or Deposit  Securities,  in
both  cases  irrevocably  deposited  by the Trust for the  payment of the amount
needed to redeem the APS  subject  to  redemption  or to satisfy  any of (i) (B)
through (i) (F). For purposes of the foregoing,  "Maximum  Potential  Additional
Dividend  Liability," as of any Valuation  Date,  means the aggregate  amount of
Additional  Dividends  that would be due if the Trust  were to make  Retroactive
Taxable  Allocations,  with  respect to any fiscal  year,  estimated  based upon
dividends  paid and the amount of  undistributed  realized net capital gains and
other taxable  income earned by the Trust,  as of the end of the calendar  month
immediately preceding such Valuation Date and assuming such Additional Dividends
are fully taxable.

      The Discount  Factors and guidelines for  determining  the market value of
the  Trust's  portfolio  holdings  have been based on  criteria  established  in
connection with rating the APS. These factors  include,  but are not limited to,
the sensitivity of the market value of the relevant asset to changes in interest
rates,  the liquidity and depth of the market for the relevant asset, the credit
quality  of the  relevant  asset  (for  example,  the lower the rating of a debt
obligation, the higher the related discount factor) and the frequency with which
the relevant asset is marked to market.  In no event shall the Discounted  Value


                                       34
<PAGE>

of any asset of the Trust exceed its unpaid principal  balance or face amount as
of the date of  calculation.  The Discount  Factor  relating to any asset of the
Trust and the APS Basic Maintenance Amount, the assets eligible for inclusion in
the  calculation  of the Discounted  Value of the Trust's  portfolio and certain
definitions and methods of calculation relating thereto may be changed from time
to time by the Trust,  without shareholder  approval,  but only in the event the
Trust receives written  confirmation  from S&P, and any Substitute Rating Agency
that any such changes  would not impair the ratings then  assigned to the APS by
S&P or any Substitute Rating Agency.

      On or before the third  Business  Day after a Valuation  Date on which the
Trust fails to maintain S&P Eligible Assets with an aggregate  Discounted  Value
equal to or greater than the APS Basic Maintenance Amount, the Trust is required
to deliver to the Auction Agent and S&P a report with respect to the calculation
of the APS Basic Maintenance  Amount and the value of its portfolio  holdings as
of the date of such failure (an "APS Basic Maintenance  Report").  Additionally,
on or before the third  Business  Day after the first day of a Special  Dividend
Period,  the Trust will deliver an APS Basic  Maintenance  Report to S&P and the
Auction Agent. The Trust also will deliver an APS Basic Maintenance Report as of
the last  Business Day of the last month of each fiscal  quarter of the Trust on
or before the third Business Day after such day.  Within ten Business Days after
delivery of such report  relating to the last  Business Day of the last month of
each fiscal  quarter of the Trust,  the Trust will deliver a letter  prepared by
the Trust's independent  accountants  regarding the accuracy of the calculations
made by the Trust in its most recent APS Basic Maintenance  Report.  Also, on or
before 5:00 p.m.,  New York City time, on the first Business Day after shares of
Common Shares are repurchased by the Trust,  the Trust will complete and deliver
to S&P an APS Basic Maintenance  Report as of the close of business on such date
that Common Shares is  repurchased.  If any such letter  prepared by the Trust's
independent  accountants  shows  that an error was made in the most  recent  APS
Basic Maintenance  Report,  the calculation or determination made by the Trust's
independent accountants will be conclusive and binding on the Trust.

REDEMPTION

      OPTIONAL REDEMPTION.  To the extent permitted under the 1940 Act and under
Massachusetts  law, upon giving a Notice of Redemption,  as provided below,  the
Trust,  at its  option,  may redeem the APS,  in whole or in part,  out of funds
legally available  therefor,  at the Optional  Redemption Price per share on any
Dividend Payment Date; provided that no APS may be redeemed at the option of the
Trust  during (a) the Initial  Dividend  Period with respect to the APS or (b) a
Non-Call  Period to which such share is  subject.  "Optional  Redemption  Price"
means  $25,000 per share of APS plus an amount equal to  accumulated  but unpaid
dividends  (whether or not earned or declared) to the date fixed for  redemption
plus any applicable  redemption premium, if any, attributable to the designation
of a Premium Call Period. In addition, holders of APS may be entitled to receive
Additional  Dividends  in the  event of  redemption  of such  APS to the  extent
provided herein. See "Description of APS--Dividends--Additional  Dividends." The
Trust has the  authority  to redeem the APS for any reason and may redeem all or
part of the outstanding APS if it anticipates that the Trust's leveraged capital
structure  will result in a lower rate of return to holders of Common Shares for
any  significant  period of time than that  obtainable if the Common Shares were
unleveraged.

      MANDATORY  REDEMPTION.  The Trust will be required to redeem, out of funds
legally available therefor, at the Mandatory Redemption Price per share, the APS
to the extent  permitted  under the 1940 Act and  Massachusetts  law,  on a date
fixed by the Board of  Trustees,  if the Trust  fails to maintain  S&P  Eligible
Assets with an aggregate Discounted Value equal to or greater than the APS Basic
Maintenance  Amount  or to  satisfy  the 1940 Act APS  Asset  Coverage  and such
failure  is not cured on or before  the APS Basic  Maintenance  Cure Date or the
1940 Act Cure Date (herein  collectively  referred to as a "Cure Date"),  as the
case may be. "Mandatory Redemption Price" of APS means $25,000 per share plus an
amount  equal to  accumulated  but unpaid  dividends  (whether  or not earned or
declared) to the date fixed for redemption.  In addition,  holders of APS may be
entitled to receive Additional  Dividends in the event of redemption of such APS
to the extent provided herein.  See  "Description of  APS--Dividends--Additional
Dividends."  The number of APS to be redeemed will be equal to the lesser of (a)
the minimum  number of APS the  redemption of which,  if deemed to have occurred
immediately prior to the opening of business on the Cure Date, together with all
other shares of the Preferred Shares subject to redemption or retirement,  would
result in the Trust having S&P Eligible Assets each with an aggregate Discounted


                                       35
<PAGE>

Value equal to or greater than the APS Basic Maintenance  Amount or satisfaction
of the 1940 Act APS  Asset  Coverage,  as the case  may be,  on such  Cure  Date
(provided  that, if there is no such minimum  number of shares the redemption of
which  would  have  such  result,  all  shares of APS then  outstanding  will be
redeemed),  and (b) the maximum number of APS, together with all other shares of
Preferred  Shares subject to redemption or retirement,  that can be redeemed out
of funds expected to be legally  available  therefor on such redemption date. In
determining  the number of APS  required to be redeemed in  accordance  with the
foregoing,  the Trust shall  allocate the number  required to be redeemed  which
would  result  in the  Trust  having  S&P  Eligible  Assets  with  an  aggregate
Discounted  Value equal to or greater than the APS Basic  Maintenance  Amount or
satisfaction  of the 1940 Act APS Asset  Coverage,  as the case may be, pro rata
among shares of APS and other Preferred Shares subject to redemption pursuant to
provisions similar to those set forth below;  provided that, shares of APS which
may not be  redeemed  at the  option of the Trust  due to the  designation  of a
Non-Call  Period  applicable  to such  shares (A) will be  subject to  mandatory
redemption only to the extent that other shares are not available to satisfy the
number of shares required to be redeemed and (B) will be selected for redemption
in an ascending order of outstanding number of days in the Non-Call Period (with
shares with the lowest  number of days to be  redeemed  first) and by lot in the
event of shares  having an equal  number of days in such  Non-Call  Period.  The
Trust is required to effect such a mandatory  redemption  not later than 35 days
after such Cure  Date,  except  that if the Trust  does not have  funds  legally
available  for the  redemption  of all of the  required  number of shares of APS
which are subject to mandatory  redemption  or the Trust  otherwise is unable to
effect such  redemption  on or prior to 35 days after such Cure Date,  the Trust
will redeem those APS which it was unable to redeem on the earliest  practicable
date on which it is able to effect such redemption.

      GENERAL.  If the APS are to be redeemed,  a notice of  redemption  will be
mailed  to each  record  holder of such APS  (initially  IBT as  nominee  of the
Securities  Depository)  and to the Auction Agent not less than 17 nor more than
30 days  prior to the date  fixed for the  redemption  thereof.  Each  notice of
redemption will include a statement setting forth: (i) the redemption date, (ii)
the aggregate number of APS to be redeemed, (iii) the redemption price, (iv) the
place or places where APS are to be  surrendered  for payment of the  redemption
price, (v) a statement that dividends on the shares to be redeemed will cease to
accumulate  on such  redemption  date  (except  that  holders may be entitled to
Additional  Dividends) and (vi) the provision of the Amended By-Laws pursuant to
which such shares are being  redeemed.  The notice also will be published in The
Wall Street Journal.  No defect in the notice of redemption or in the mailing or
publication  thereof  will affect the  validity of the  redemption  proceedings,
except as required by applicable law.

      In the event that less than all of the outstanding APS are to be redeemed,
the shares to be redeemed  will be  selected by lot or such other  method as the
Trust  shall  deem  fair  and  equitable,   and  the  results  thereof  will  be
communicated  to the Auction  Agent.  The Auction  Agent will give notice to the
Securities  Depository,  whose nominee will be the record holder of all APS, and
the  Securities  Depository  will  determine the number of shares to be redeemed
from the account of the Agent Member of each Existing Holder.  Each Agent Member
will  determine  the number of shares to be  redeemed  from the  account of each
Existing  Holder  for which it acts as agent.  An Agent  Member  may  select for
redemption  shares from the accounts of some Existing Holders without  selecting
for  redemption  any  shares  from  the  accounts  of  other  Existing  Holders.
Notwithstanding  the  foregoing,  if neither the  Securities  Depository nor its
nominee is the record holder of all of the APS series,  the particular shares to
be redeemed shall be selected by the Trust by lot or by such other method as the
Trust shall deem fair and equitable.

      If the Trust gives notice of redemption,  and  concurrently  or thereafter
deposits in trust with the Auction  Agent,  or  segregates  in an account at the
Trust's custodian bank for the benefit of the Auction Agent,  Deposit Securities
(with a right of substitution)  having an aggregate  Discounted Value (utilizing
an S&P Exposure Period of 22 Business Days) equal to the redemption  payment for
the APS as to which  notice  of  redemption  has been  given,  with  irrevocable
instructions  and authority to pay the  redemption  price to the record  holders
thereof, then upon the date of such deposit or, if no such deposit is made, upon
such date fixed for redemption (unless the Trust shall default in making payment
of the  redemption  price),  all rights of the holders of such shares called for
redemption will cease and terminate, except the right of such holders to receive
the redemption price thereof and any Additional Dividends, but without interest,
and such  shares no longer will be deemed to be  outstanding.  The Trust will be
entitled to receive,  from time to time,  the interest,  if any,  earned on such
Deposit  Securities  deposited  with the Auction  Agent,  and the holders of any
shares  so  redeemed  will  have no  claim to any such  interest.  Any  funds so
deposited  which are unclaimed at the end of one year from such  redemption date
will be repaid, upon demand, to the Trust, after which the holders of the APS of
such  series so called  for  redemption  may look only to the Trust for  payment
thereof.

      So long as any APS are held of record  by the  nominee  of the  Securities
Depository (initially _____________),  the redemption price for such shares will
be paid on the redemption date to the nominee of the Securities Depository.  The


                                       36
<PAGE>

Securities  Depository's  normal procedures now provide for it to distribute the
amount of the  redemption  price to Agent Members who, in turn,  are expected to
distribute such funds to the persons for whom they are acting as agent.

      Notwithstanding  the  provisions for redemption  described  above,  no APS
shall be subject to optional  redemption  (i) unless all dividends in arrears on
the outstanding APS, and all capital stock of the Trust ranking on a parity with
the APS with respect to the payment of dividends or upon liquidation,  have been
or are being  contemporaneously  paid or declared  and set aside for payment and
(ii) if redemption  thereof would result in the Trust's  failure to maintain S&P
Eligible Assets with an aggregate  Discounted Value equal to or greater than the
APS Basic Maintenance Amount.

LIQUIDATION RIGHTS

      Upon any  liquidation,  dissolution  or winding  up of the Trust,  whether
voluntary or involuntary, the holders of APS will be entitled to receive, out of
the assets of the Trust available for distribution to  shareholders,  before any
distribution  or payment is made upon any Common  Shares or any other  shares of
beneficial  interest  of the  Trust  ranking  junior  in right of  payment  upon
liquidation of APS,  $25,000 per share together with the amount of any dividends
accumulated but unpaid  (whether or not earned or declared)  thereon to the date
of  distribution,  and after such payment the holders of APS will be entitled to
no other  payments  except for any Additional  Dividends.  If such assets of the
Trust shall be insufficient to make the full liquidation  payment on outstanding
APS and  liquidation  payments  on any  other  outstanding  class or  series  of
Preferred  Shares of the Trust  ranking  on a parity  with the APS as to payment
upon liquidation,  then such assets will be distributed among the holders of APS
and the holders of shares of such other class or series ratably in proportion to
the respective preferential amounts to which they are entitled. After payment of
the full amount of  liquidation  distribution  to which they are  entitled,  the
holders  of  APS  will  not be  entitled  to any  further  participation  in any
distribution  of assets by the Trust  except  for any  Additional  Dividends.  A
consolidation,  merger or share  exchange  of the  Trust  with or into any other
entity or entities or a sale,  whether for cash, shares of stock,  securities or
properties,  of all or substantially  all or any part of the assets of the Trust
shall not be deemed or construed to be a liquidation,  dissolution or winding up
of the Trust.

VOTING RIGHTS

      Except as otherwise  indicated in this  Prospectus and except as otherwise
required  by  applicable  law,  holders of APS will be  entitled to one vote per
share on each matter  submitted to a vote of shareholders and will vote together
with holders of Common Shares and other Preferred Shares as a single class.

      In connection  with the election of the Trust's  trustees,  holders of the
APS and any  other  Preferred  Shares,  voting  as a  separate  class,  shall be
entitled at all times to elect two of the Trust's  trustees,  and the  remaining
trustees  will be  elected  by  holders  of Common  Shares and APS and any other
Preferred Shares, voting together as a single class. In addition, if at any time
dividends on outstanding  APS shall be unpaid in an amount equal to at least two
full  years'  dividends  thereon  or if at any time  holders  of any  shares  of
Preferred  Shares are  entitled,  together  with the  holders of APS, to elect a
majority of the  trustees  of the Trust  under the 1940 Act,  then the number of
trustees constituting the Board of Trustees  automatically shall be increased by
the smallest number that, when added to the two trustees elected  exclusively by
the holders of APS and any other  Preferred  Shares as  described  above,  would
constitute a majority of the Board of Trustees as so increased by such  smallest
number,  and at a special meeting of shareholders  which will be called and held
as soon as practicable,  and at all subsequent meetings at which trustees are to
be elected,  the holders of the APS and any other Preferred Shares,  voting as a
separate  class,  will be entitled to elect the  smallest  number of  additional
trustees  that,  together with the two trustees  which such holders in any event
will be  entitled  to elect,  constitutes  a  majority  of the  total  number of
trustees  of the Trust as so  increased.  The terms of office of the persons who
are trustees at the time of that election will continue. If the Trust thereafter
shall pay, or declare and set apart for payment in full,  all dividends  payable
on all  outstanding  APS and any other  Preferred  Shares for all past  Dividend
Periods,  the  additional  voting  rights  of the  holders  of APS and any other
Preferred  Shares as described above shall cease, and the terms of office of all
of the additional trustees elected by the holders of APS and any other Preferred
Shares (but not of the trustees  with  respect to whose  election the holders of
Common  Shares were  entitled to vote or the two trustees the holders of APS and
any other Preferred  Shares have the right to elect in any event) will terminate
automatically.


                                       37
<PAGE>

      The  affirmative  vote of a majority  of the votes  entitled to be cast by
holders of outstanding APS and any other Preferred Shares,  voting as a separate
class, will be required to (i) authorize, create or issue any class or series of
stock  ranking  prior to the APS or any other  series of  Preferred  Shares with
respect  to  the  payment  of  dividends  or  the   distribution  of  assets  on
liquidation;  provided,  however,  that no vote is  required  to  authorize  the
issuance of another class of Preferred Shares which are substantially  identical
in all respects to the APS or (ii) amend,  alter or repeal the provisions of the
Declaration of Trust or the Amended By-Laws, whether by merger, consolidation or
otherwise,  so as to adversely  affect any of the contract rights  expressly set
forth in the  Declaration  of Trust or the Amended  By-Laws of holders of APS or
any other Preferred  Shares.  To the extent permitted under the 1940 Act, in the
event shares of more than one series of APS are outstanding, the Trust shall not
approve  any of the  actions  set forth in clause  (i) or (ii)  which  adversely
affects the contract rights expressly set forth in the Declaration of Trust of a
holder of shares of a series of APS differently than those of a holder of shares
of any other series of APS without the  affirmative  vote of at least a majority
of votes  entitled  to be cast by holders  of the  shares of APS of each  series
adversely  affected and  outstanding at such time (each such adversely  affected
series voting separately as a class).  The Board of Trustees,  however,  without
shareholder  approval,  may  amend,  alter or repeal  any or all of the  various
rating  agency  guidelines  described  herein in the  event  the Trust  receives
confirmation  from the rating  agencies that any such  amendment,  alteration or
repeal  would not impair the ratings then  assigned to the APS.  Unless a higher
percentage  is  provided  for  under  "Description  of  Capital   Stock--Certain
Provisions in the Declaration of Trust," the  affirmative  vote of a majority of
the  votes  entitled  to be cast by  holders  of  outstanding  APS and any other
Preferred  Shares,  voting as a separate class,  will be required to approve any
plan of reorganization  (including bankruptcy  proceedings)  adversely affecting
such shares or any action  requiring a vote of security  holders  under  Section
13(a) of the 1940 Act  including,  among  other  things,  changes in the Trust's
investment  objective  or changes in the  investment  restrictions  described as
fundamental  policies under "Investment  Objective and Policies." The class vote
of holders of shares of APS and any other  Preferred  Shares  described above in
each case will be in addition to a separate vote of the requisite  percentage of
Common  Shares and APS and any other  Preferred  Shares,  voting  together  as a
single class, necessary to authorize the action in question.

      The foregoing voting  provisions will not apply to the APS if, at or prior
to the time when the act with  respect  to which  such vote  otherwise  would be
required  shall be  effected,  such shares  shall have been (i) redeemed or (ii)
called for redemption and sufficient funds shall have been deposited in trust to
effect such redemption.

                             MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES

      The management of the Trust,  including general  supervision of the duties
performed by the Adviser under the Advisory Agreement,  is the responsibility of
the  Trust's  Board  of  Trustees  under  the  laws  of  The   Commonwealth   of
Massachusetts.

THE ADVISER

      Eaton Vance  Management  acts as the Trust's  investment  adviser under an
Investment Advisory Agreement  ("Advisory  Agreement").  The Adviser's principal
office is located at 24 Federal  Street,  Boston,  MA 02110.  Eaton  Vance,  its
affiliates and  predecessor  companies have been managing  assets of individuals
and institutions since 1924 and of investment  companies since 1931. Eaton Vance
(or its  affiliates)  currently  serves as the investment  adviser to investment
companies and various individual and institutional  clients with combined assets
under management of over $31 billion,  of which  approximately $28 billion is in
investment  companies.  Eaton Vance is a wholly-owned  subsidiary of Eaton Vance
Corp.,  a publicly  held holding  company  which  through its  subsidiaries  and
affiliates  engages  primarily  in  investment  management,  administration  and
marketing activities.

      Eaton  Vance  employs  24  personnel  in its  municipal  bond  department,
including six portfolio managers, two traders and eleven credit analysts.  Eaton
Vance was one of the first advisory firms to manage a registered  municipal bond
investment  company,  and has  done so  continuously  since  1978.  Eaton  Vance
currently manages 3 national  municipal  investment  companies,  33 single state
municipal  investment  companies,   10  limited  maturity  municipal  investment
companies and 1 money market municipal investment company,  with assets of about
$8 billion.

      Under the  general  supervision  of the  Trust's  Board of  Trustees,  the
Adviser  will carry out the  investment  and  reinvestment  of the assets of the
Trust,  will  furnish  continuously  an  investment  program with respect to the
Trust, will determine which securities  should be purchased,  sold or exchanged,
and will  implement such  determinations.  The Adviser will furnish to the Trust
investment advice and office  facilities,  equipment and personnel for servicing
the  investments  of the Trust.  The Adviser  will  compensate  all Trustees and
officers  of the Trust who are  members of the  Adviser's  organization  and who
render  investment  services to the Trust,  and will also  compensate  all other
Adviser personnel who provide research and investment  services to the Trust. In
return for these services,  facilities and payments, the Trust has agreed to pay
the Adviser as compensation  under the Advisory Agreement a fee in the amount of
 .70% of the average weekly gross assets of the Trust.  Gross assets of the Trust
shall be calculated by deducting accrued  liabilities of the Trust not including
the amount of any Preferred Shares outstanding.

      Thomas M. Metzold is the portfolio manager of the Trust and is responsible
for day-to-day  management of the Trust's  investments.  Mr. Metzold has been an
employee  of Eaton Vance  since 1987 and a Vice  President  of Eaton Vance since
1991. Mr.  Metzold,  a Chartered  Financial  Analyst,  is a member of the Boston
Security Analysts Society, the Association for Investment Management & Research,
the Boston Municipal  Analysts Forum,  and the National  Federation of Municipal
Analysts.  He currently  manages four municipal bond  investment  companies with
combined assets of over $2.8 billion.

      The  Trust and the  Adviser  have  adopted  Codes of  Ethics  relating  to
personal securities  transactions.  The Codes permit Adviser personnel to invest
in securities  (including securities that may be purchased or held by the Trust)
for their own accounts,  subject to certain  pre-clearance,  reporting and other
restrictions and procedures contained in such Codes.

      The Trust has  engaged  Eaton Vance to act as its  administrator  under an
Administration   Agreement   (the   "Administration   Agreement").   Under   the
Administration  Agreement,  Eaton Vance is responsible for managing the business
affairs  of the  Trust,  subject  to the  supervision  of the  Trust's  Board of
Trustees. Eaton Vance will furnish to the Trust all office facilities, equipment
and  personnel  for  administering  the  affairs  of the  Trust.  Eaton  Vance's


                                       39
<PAGE>

administrative  services  include  recordkeeping,   preparation  and  filing  of
documents required to comply with federal and state securities laws, supervising
the activities of the Trust's custodian and transfer agent, providing assistance
in connection with the Trustees' and shareholders'  meetings,  providing service
in  connection  with any  repurchase  offers and other  administrative  services
necessary  to  conduct  the  Trust's  business.  In return  for these  services,
facilities  and  payments,  the  Trust  is  authorized  to pay  Eaton  Vance  as
compensation under the  Administration  Agreement a fee in the amount of .20% of
the average weekly gross assets of the Trust.

      Eaton Vance has agreed to bear all ordinary and organizational expenses of
the Trust that exceed 5% of average  weekly net assets  (taking into account the
deduction of any  Preferred  Shares and related  expenses) for the first year of
operations. In return for this arrangement, the Trust will reimburse Eaton Vance
over the first year of operations for organizational expenses of the Trust borne
by Eaton Vance at the onset of operations.

                                      TAXES

GENERAL

      The Trust  intends to elect and to qualify for the  special tax  treatment
afforded regulated investment companies ("RICs") under the Internal Revenue Code
of 1986,  as amended (the "Code").  As long as it so  qualifies,  in any taxable
year in which it  distributes  at least 90% of its taxable net income and 90% of
its tax-exempt net income (see below), the Trust (but not its shareholders) will
not be subject to Federal income tax to the extent that it  distributes  its net
investment  income  and  net  realized  capital  gains.  The  Trust  intends  to
distribute substantially all of such income.

      The Internal Revenue Service (the "IRS"),  in a revenue ruling,  held that
certain  auction  rate  Preferred  Shares  would be treated as stock for Federal
income tax purposes.  The terms of the APS are  substantially  similar,  but not
identical, to the auction rate Preferred Shares discussed in the revenue ruling,
and in the opinion of Kirkpatrick & Lockhart LLP,  counsel to the Trust, the APS
will constitute stock of the Trust and distributions  with respect to APS (other
than  distributions  in redemption of APS subject to Section 302(b) of the Code)
will  constitute  dividends to the extent of the Trust's current and accumulated
earnings  and  profits  as   calculated   for  Federal   income  tax   purposes.
Nevertheless,  it is  possible  that the IRS  might  take a  contrary  position,
asserting,  for  example,  that the APS  constitute  debt of the Trust.  If this
position were upheld,  the  discussion of the treatment of  distributions  below
would not  apply.  Instead,  distributions  by the Trust to holders of APS would
constitute  interest,  whether or not they  exceeded the earnings and profits of
the Trust, would be included in full in the income of the recipient and would be
taxed as ordinary income.  Counsel believes that such a position, if asserted by
the IRS, would be unlikely to prevail.

      Each dividend  distribution  ordinarily will constitute income exempt from
regular  federal  income tax.  Distributions  of  interest on certain  Municipal
Obligations,  however,  are a tax preference item under the federal  alternative
minimum tax.  Moreover,  distributions of any taxable net investment  income and
net  short-term   capital  gain  are  taxable  as  ordinary   income.   Finally,
distributions  of the Trust's net capital gain  ("capital gain  dividends"),  if
any, are taxable to shareholders as long-term  capital gains,  regardless of the
length of time shares have been held by shareholders.  Distributions, if any, in
excess of the Trust's  earnings  and profits  will first reduce the adjusted tax
basis of a holder's  shares and, after that basis has been reduced to zero, will
constitute  capital gains to the Shareholder  (assuming the Shares are held as a
capital asset).

      The Trust  will  inform  shareholders  of the source and tax status of all
distributions  promptly after the close of each calendar year. The IRS has taken
the  position  in a  revenue  ruling  that if a RIC has more  than one  class of
shares,  it may  designate  distributions  made to  each  class  in any  year as
consisting of no more than such class's  proportionate share of particular types
of income, including exempt interest and net long-term capital gains (as well as
the new categories of capital gains referred to above). A class's  proportionate
share of a particular  type of income is determined  according to the percentage
of total dividends paid by the RIC during such year that was paid to such class.
Thus,  the Trust is required to allocate a portion of its net capital  gains and
other taxable  income to each series of Preferred  Shares.  The Trust  generally
will notify the Auction  Agent of the amount of any net capital  gains and other
taxable  income to be included  in any  dividend on the APS prior to the Auction


                                       40
<PAGE>

establishing  the Applicable  Rate for such dividend.  Except for the portion of
any dividend  that it informs the Auction Agent will be treated as capital gains
or other taxable income,  the Trust  anticipates  that the dividends paid on the
APS will constitute  exempt-interest  dividends. The amount of net capital gains
and ordinary  income  allocable  to the APS (the  "taxable  distribution")  will
depend  upon the amount of such gains and income  realized  by the Trust and the
total  dividends  paid by the Trust on its  Common  Shares  and the APS during a
taxable  year,  but the taxable  distribution  generally  is not  expected to be
significant. In the opinion of Kirkpatrick & Lockhart LLP, counsel to the Trust,
under  current law the manner in which the Trust  intends to  allocate  items of
tax-exempt  income,  net capital gains, and other taxable income,  if any, among
the Trust's  Common Shares and the APS will be respected for Federal  income tax
purposes.  However,  the tax  treatment of  Additional  Dividends may affect the
Trust's  calculation of each class'  allocable  share of capital gains and other
taxable income. See "Tax Treatment of Additional Dividends." In addition,  there
is  currently  no direct  guidance  from the IRS or other  sources  specifically
addressing  whether the Trust's method for  allocating  tax-exempt  income,  net
capital gains,  and other taxable income among Common Shares and the APS will be
respected for Federal income tax purposes, and it is possible that the IRS could
disagree  with  counsel's  opinion  and  attempt to  reallocate  the Trust's net
capital gains or other taxable income.  In the event of a reallocation,  some of
the dividends identified by the Trust as exempt-interest dividends to holders of
APS may be  recharacterized as additional capital gains or other taxable income.
In the event of such recharacterization, the Trust would not be required to make
payments to such shareholders to offset the tax effect of such reallocation.  In
addition,  a  reallocation  may cause the Trust to be liable  for income tax and
excise tax on any  reallocated  taxable  income.  Kirkpatrick & Lockhart LLP has
advised the Trust that,  in its  opinion,  if the IRS were to challenge in court
the  Trust's  allocations  of income  and gain,  the IRS  would be  unlikely  to
prevail.  A holder should be aware,  however,  that the opinion of Kirkpatrick &
Lockhart LLP  represents  only its best legal judgment and is not binding on the
IRS or the courts.

      If at any time when shares of APS are  outstanding the Trust does not meet
the asset coverage  requirements  of the 1940 Act, the Trust will be required to
suspend  distributions  to holders of Common Shares until the asset  coverage is
restored.   See  "Description  of   APS--Restrictions  on  Dividends  and  Other
Payments." This may prevent the Trust from  distributing at least 90% of its net
income, and may, therefore, jeopardize the Trust's qualification for taxation as
a RIC. Upon any failure to meet the asset coverage requirements of the 1940 Act,
the Trust, in its sole discretion, may redeem shares of APS in order to maintain
or restore the requisite  asset coverage and avoid the adverse  consequences  to
the Trust and its  shareholders of failing to qualify as a RIC. See "Description
of APS--Redemption."  There can be no assurance,  however,  that any such action
would achieve such objectives.

      As noted above, the Trust must distribute annually at least 90% of its net
taxable and tax-exempt  interest income. A distribution will only be counted for
this purpose if it qualifies for the dividends  paid  deduction  under the Code.
Some types of Preferred Shares that the Trust currently contemplates issuing may
raise  an  issue  as to  whether  distributions  on such  Preferred  Shares  are
"preferential"  under the Code and therefore not eligible for the dividends paid
deduction. The Trust intends to issue Preferred Shares that counsel advises will
not result in the  payment  of a  preferential  dividend  and may seek a private
letter ruling from the IRS to that effect. If the Trust ultimately relies solely
on a legal opinion when it issues such Preferred  Shares,  there is no assurance
that  the IRS  would  agree  that  dividends  on the  Preferred  Shares  are not
preferential.  If the IRS  successfully  disallowed the dividends paid deduction
for dividends on the Preferred  Shares,  the Trust could lose the benefit of the
special treatment  afforded RICs under the Code. In this case,  dividends on the
Common Shares would not be exempt from Federal income taxes.  Additionally,  the
Trust would be subject to the alternative minimum tax.

<PAGE>

TAX TREATMENT OF ADDITIONAL DIVIDENDS

      If  the  Trust  makes  a  Retroactive  Taxable  Allocation,  it  will  pay
Additional  Dividends  to  holders  of APS who are  subject  to the  Retroactive
Taxable Allocation. See "Description of  APS--Dividends--Additional  Dividends."
The Federal income tax  consequences of Additional  Dividends under existing law
are  uncertain.  The Trust  intends  to treat a holder as  receiving  a dividend
distribution  in the  amount of any  Additional  Dividend  only as and when such
Additional Dividend is paid. An Additional Dividend generally will be designated
by the Trust as an  exempt-interest  divided  except as  otherwise  required  by
applicable  law.  However,  the IRS may assert that all or part of an Additional
Dividend  is a  taxable  dividend  either  in the  taxable  year for  which  the
Retroactive  Taxable  Allocation  is made or in the  taxable  year in which  the
Additional Dividend is paid.

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

      The foregoing briefly  summarizes some of the important federal income tax
consequences  of investing  in the APS,  reflects the federal tax law, as of the
date of this  Prospectus,  and does not address special tax rules  applicable to
certain types of investors,  such as corporate and foreign investors.  There may
be other federal,  state or local tax considerations  applicable to a particular
investor,  including state  alternative  minimum tax.  Investors  should consult
their tax advisers.

                        DESCRIPTION OF CAPITAL STRUCTURE

      The Trust is an  unincorporated  business trust established under the laws
of the  Commonwealth of  Massachusetts  by an Agreement and Declaration of Trust
dated December 10, 1998 (the  "Declaration of Trust").  The Declaration of Trust
provides that the Trustees of the Trust may authorize separate classes of shares
of  beneficial  interest.  The Trustees have  authorized an unlimited  number of
shares of  beneficial  interest  stock,  par value $.01 per share,  all of which
shares were initially classified as Common Shares. The Declaration of Trust also
authorizes the issuance of an unlimited number of shares of beneficial  interest
with preference rights,  including Preferred Shares, having a par value of $0.01
per share,  in one or more  series,  with rights as  determined  by the Board of
Trustees,  by  action of the  Board of  Trustees  without  the  approval  of the
Shareholders.  For a  description  of the APS,  see  "Description  of APS."  The
following table shows the amount of (i) shares  authorized,  (ii) shares held by
the Trust for its own account and (iii)  shares  outstanding,  for each class of
authorized securities of the Trust as of _____________, 1999.

      COMMON SHARES

      Holders  of Common  Shares are  entitled  to share  equally  in  dividends
declared by the Board of Trustees payable to holders of Common Shares and in the
net assets of the Trust  available for  distribution to holders of Common Shares
after payment of the preferential  amounts payable to holders of any outstanding
Preferred  Shares.  Neither  holders of Common  Shares nor holders of  Preferred
Shares have preemptive or conversion  rights and shares of Common Shares are not
redeemable.  Upon liquidation of the Trust, after paying or adequately providing
for the payment of all liabilities of the Trust and the  liquidation  preference
with  respect to any  outstanding  preferred  shares,  and upon  receipt of such


                                       42
<PAGE>

releases,  indemnities and refunding agreements as they deem necessary for their
protection,  the Trustees may distribute the remaining assets of the Trust among
the holders of the Shares.  The Declaration of Trust provides that  Shareholders
are not liable for any liabilities of the Trust,  requires inclusion of a clause
to that  effect in every  agreement  entered  into by the Trust and  indemnifies
shareholders   against  any  such   liability.   Although   shareholders  of  an
unincorporated  business trust established under  Massachusetts  law, in certain
limited circumstances,  may be held personally liable for the obligations of the
Trust as though they were general partners, the provisions of the Declaration of
Trust  described in the foregoing  sentence make the likelihood of such personal
liability remote.

      Holders of Common  Shares are entitled to one vote for each share held and
will vote with the holders of any outstanding  APS or other Preferred  Shares on
each matter submitted to a vote of holders of Common Shares, except as described
under "Description of APS--Voting Rights."

      Shareholders  are entitled to one vote for each share held.  The shares of
Common Shares,  APS and any other Preferred Shares do not have cumulative voting
rights,  which  means that the  holders of more than 50% of the shares of Common
Shares,  APS and any other Preferred  Shares voting for the election of Trustees
can elect all of the Trustees  standing for  election by such  holders,  and, in
such event,  the holders of the remaining  shares of Common Shares,  APS and any
other Preferred Shares will not be able to elect any of such Trustees.

      So  long  as  any  shares  of  APS  or  any  other  Preferred  Shares  are
outstanding,  holders of Common  Shares  will not be  entitled  to  receive  any
dividends of or other  distributions from the Trust,  unless at the time of such
declaration,  (i) all accrued  dividends on preferred shares or accrued interest
on  borrowings  has been  paid and (2) the  value of the  Trust's  total  assets
(determined after deducting the amount of such dividend or other  distribution),
less all  liabilities  and  indebtedness  of the Trust not represented by senior
securities,  is at  least  300%  of the  aggregate  amount  of  such  securities
representing  indebtedness  and  at  least  200%  of  the  aggregate  amount  of
securities representing indebtedness plus the aggregate liquidation value of the
outstanding  preferred shares (expected to equal the aggregate original purchase
price of the  outstanding  preferred  shares plus  redemption  premium,  if any,
together with any accrued and unpaid dividends thereon, whether or not earned or
declared and on a cumulative basis). In addition to the requirements of the 1940
Act, the Trust is required to comply with other asset coverage requirements as a
condition of the Trust obtaining a rating of the preferred  shares from a Rating
Agency.  These  requirements  include an asset coverage test more stringent than
under the 1940 Act. See "Description of APS--Restrictions on Dividends and Other
Payments."

      The Trust will send unaudited  reports at least  semi-annually and audited
financial statements annually to all of its shareholders.

      The  shares of Common  Shares  commenced  trading on the NYSE on _______ ,
1999. At ___ , 1999,  the net asset value per share of Common Shares was $_____,
and the closing price per share of Common Shares on the NYSE was $_____.

PREFERRED SHARES

      Under the Amended  By-Laws,  the Trust is authorized to issue an aggregate
of ______  APS.  See  "Description  of APS."  Under  the 1940 Act,  the Trust is
permitted to have  outstanding  more than one series of Preferred Shares as long
as no single series has priority over another series as to the  distribution  of
assets of the Trust or the  payment  of  dividends.  Neither  holders  of Common
Shares nor holders of Preferred  Shares have  preemptive  rights to purchase any
shares  of APS or any  other  Preferred  Shares  that  might  be  issued.  It is
anticipated  that the net  asset  value  per  share of the APS  will  equal  its
original purchase price per share plus accumulated dividends per share.

                       CERTAIN PROVISIONS OF THE DECLARATION OF TRUST

      ANTI-TAKEOVER  PROVISIONS IN THE DECLARATION OF TRUST.  The Declaration of
Trust includes  provisions that could have the effect of limiting the ability of
other  entities  or  persons  to  acquire  control of the Trust or to change the
composition  of its Board of  Trustees,  and could have the effect of  depriving
Shareholders of an opportunity to sell their Shares at a premium over prevailing
market prices by  discouraging  a third party from seeking to obtain  control of
the Trust.  These  provisions  may have the effect of  discouraging  attempts to
acquire control of the Trust, which attempts could have the effect of increasing
the  expenses  of the Trust and  interfering  with the normal  operation  of the
Trust. The Board of Trustees is divided into three classes, with the term of one
class expiring at each annual meeting of  Shareholders.  At each annual meeting,
one class of Trustees is elected to a  three-year  term.  This  provision  could

                                       43
<PAGE>

delay  for up to two  years  the  replacement  of a  majority  of the  Board  of
Trustees.  A Trustee  may be  removed  from  office  only for cause by a written
instrument  signed by the  remaining  Trustees or by a vote of the holders of at
least  two-thirds  of the class of Shares of the Trust that elected such Trustee
and is entitled to vote on the matter.

      In addition,  the  Declaration of Trust requires the favorable vote of the
holders  of at least 75% of the  outstanding  shares of each class of the Trust,
voting as a class, then entitled to vote to approve,  adopt or authorize certain
transactions  with  5%-or-greater  holders  of  a  class  of  shares  and  their
associates,  unless the Board of Trustees  shall by  resolution  have approved a
memorandum  of  understanding  with such  holders,  in which case normal  voting
requirements  would  be  in  effect.   For  purposes  of  these  provisions,   a
5%-or-greater holder of a class of shares (a "Principal  Shareholder") refers to
any person who,  whether  directly or  indirectly  and whether alone or together
with  its  affiliates  and  associates,  beneficially  owns  5% or  more  of the
outstanding  shares  of any  class of  beneficial  interest  of the  Trust.  The
transactions subject to these special approval  requirements are: (i) the merger
or  consolidation  of the Trust or any  subsidiary of the Trust with or into any
Principal  Shareholder;  (ii) the issuance of any securities of the Trust to any
Principal  Shareholder for cash; (iii) the sale, lease or exchange of all or any
substantial part of the assets of the Trust to any Principal Shareholder (except
assets  having  an  aggregate  fair  market  value  of  less  than   $1,000,000,
aggregating  for the  purpose of such  computation  all assets  sold,  leased or
exchanged in any series of similar  transactions within a twelve-month  period);
or (iv) the sale, lease or exchange to the Trust or any subsidiary  thereof,  in
exchange for securities of the Trust, of any assets of any Principal Shareholder
(except  assets having an aggregate  fair market value of less than  $1,000,000,
aggregating  for the purposes of such  computation  all assets  sold,  leased or
exchanged in any series of similar transactions within a twelve-month period).

      The Board of Trustees has determined  that  provisions with respect to the
Board and the 75% voting requirements described above, which voting requirements
are greater than the minimum  requirements  under  Massachusetts law or the 1940
Act, are in the best interest of  Shareholders  generally.  Reference  should be
made to the Declaration of Trust on file with the SEC for the full text of these
provisions.

      CONVERSION  TO OPEN-END  FUND.  The Trust may be  converted to an open-end
investment  company at any time if  approved by the lesser of (i) 2/3 or more of
the Trust's then  outstanding  Common Shares and Preferred Shares (if any), each
voting  separately  as a class,  or (ii) more  than 50% of the then  outstanding
Shares and  Preferred  Shares  (if any),  voting  separately  as a class if such
conversion is  recommended  by at least 75% of the Trustees  then in office.  If
approved in the foregoing manner,  conversion of the Trust could not occur until
90 days after the  Shareholders'  meeting at which such  conversion was approved
and would also require at least 30 days' prior notice to all  Shareholders.  The
composition  of the  Trust's  portfolio  likely  would  prohibit  the Trust from
complying  with  regulations  of  the  SEC  applicable  to  open-end  investment
companies.  Accordingly,  conversion likely would require significant changes in
the Trust's investment  policies and liquidation of a substantial portion of its
relatively illiquid portfolio. Conversion of the Trust to an open-end investment
company also would require the redemption of any  outstanding  Preferred  Shares
and could require the repayment of borrowings.  The Board of Trustees  believes,
however,  that  the  closed-end  structure  is  desirable,   given  the  Trust's
investment objective and policies.  Investors should assume,  therefore, that it
is  unlikely  that the Board of  Trustees  would vote to convert the Trust to an
open-end investment company.

shall be the  arithmetic  average of the Interest  Equivalent  of the 90-day and

days,  such rate shall be the  Interest  Equivalent  of the 120-day rate on such

               ADDITIONAL INVESTMENT INFORMATION AND RESTRICTIONS

      MUNICIPAL  OBLIGATIONS.  Municipal  Obligations are issued to obtain funds
for various public and private purposes. Municipal Obligations include long-term
obligations,  which are often  called  municipal  bonds,  as well as  tax-exempt
commercial  paper,  project notes and municipal  notes such as tax,  revenue and
bond  anticipation  notes of short  maturity,  generally  less than three years.
Market rates of interest available with respect to Municipal  Obligations may be
lower than those  available  with respect to taxable  securities,  although such
differences  may be partially or wholly offset by the effects of federal  income
tax on income derived from such taxable  securities.  While most municipal bonds
pay a fixed rate of interest  semi-annually  in cash, some bonds pay no periodic
cash interest but instead make a single  payment at maturity  representing  both
principal  and interest.  Municipal  Obligations  may be issued or  subsequently
offered  with  interest  coupons  materially  greater  or less than  those  then
prevailing, with price adjustments reflecting such deviation.

      In  general,  there are three  categories  of  Municipal  Obligations  the
interest on which is exempt from federal  income tax and is not a tax preference
item for purposes of the AMT: (i) certain "public purpose" obligations (whenever
issued),   which  include   obligations  issued  directly  by  state  and  local
governments or their agencies to fulfill essential governmental functions;  (ii)
certain   obligations   issued   before  August  8,  1986  for  the  benefit  of
non-governmental persons or entities; and (iii) certain "private activity bonds"
issued after August 7, 1986 which include "qualified Section 501(c)(3) bonds" or
refundings of certain obligations  included in the second category.  Interest on
certain  "private  activity  bonds"  issued  after August 7, 1986 is exempt from
regular  federal income tax, but is treated as a tax preference  item that could
subject the recipient to or increase the recipient's  liability for the AMT. For
corporate  shareholders,  the Trust's distributions derived from interest on all
Municipal  Obligations  (whenever  issued)  is  included  in  "adjusted  current
earnings" for purposes of the AMT as applied to corporations  (to the extent not
already included in alternative minimum taxable income as income attributable to
private  activity  bonds).  In  assessing  the federal  income tax  treatment of
interest  on any such  obligation,  the  Trust  will rely on an  opinion  of the
issuer's  counsel  (when  available)  obtained  by the issuer or other  reliable
authority and will not undertake any independent verification thereof.

      The  two  principal   classifications  of  municipal  bonds  are  "general
obligation" and "revenue"  bonds.  Issuers of general  obligation  bonds include
states,  counties,  cities, towns and regional districts.  The proceeds of these
obligations  are used to fund a wide  range of  public  projects  including  the
construction  or  improvement  of schools,  highways and roads,  water and sewer
systems and a variety of other public  purposes.  The basic  security of general
obligation bonds is the issuer's pledge of its faith,  credit,  and taxing power
for the payment of principal and interest.  The taxes that can be levied for the
payment of debt service may be limited or unlimited as to rate and amount.

      Revenue  bonds are  generally  secured by the net revenues  derived from a
particular  facility or group of facilities or, in some cases, from the proceeds
of a special excise or other specific  revenue  source.  Revenue bonds have been
issued to fund a wide  variety of capital  projects  including:  electric,  gas,
water,  sewer and solid waste disposal systems;  highways,  bridges and tunnels;
port,  airport  and  parking   facilities;   transportation   systems;   housing
facilities,  colleges and  universities  and  hospitals.  Although the principal
security behind these bonds varies widely,  many provide additional  security in
the  form  of a debt  service  reserve  fund  whose  monies  may be used to make
principal and interest  payments on the issuer's  obligations.  Housing  finance
authorities have a wide range of security including  partially or fully insured,
rent subsidized and/or  collateralized  mortgages,  and/or the net revenues from


                                      B-2
<PAGE>

housing or other public  projects.  In addition to a debt service  reserve fund,
some  authorities  provide  further  security  in the form of a state's  ability
(without legal  obligation) to make up  deficiencies in the debt service reserve
fund.  Lease  rental  revenue  bonds  issued by a state or local  authority  for
capital  projects are normally  secured by annual lease rental payments from the
state or  locality  to the  authority  sufficient  to cover debt  service on the
authority's   obligations.   Such   payments  are  usually   subject  to  annual
appropriations  by the state or locality.  Industrial  development and pollution
control bonds, although nominally issued by municipal  authorities,  are in most
cases  revenue  bonds and are  generally  not secured by the taxing power of the
municipality,  but are usually secured by the revenues  derived by the authority
from payments of the industrial user or users. The Trust may on occasion acquire
revenue bonds which carry warrants or similar rights covering equity securities.
Such warrants or rights may be held  indefinitely,  but if exercised,  the Trust
anticipates  that it would,  under normal  circumstances,  dispose of any equity
securities so acquired within a reasonable period of time.

      The  obligations  of any  person  or entity  to pay the  principal  of and
interest on a Municipal  Obligation are subject to the provisions of bankruptcy,
insolvency and other laws  affecting the rights and remedies of creditors,  such
as the  Federal  Bankruptcy  Act,  and laws,  if any,  which may be  enacted  by
Congress or state  legislatures  extending  the time for payment of principal or
interest,  or both,  or imposing  other  constraints  upon  enforcement  of such
obligations.  There is also the  possibility  that as a result of  litigation or
other  conditions  the power or  ability of any person or entity to pay when due
principal of and interest on a Municipal  Obligation may be materially affected.
There  have  been  recent  instances  of  defaults  and  bankruptcies  involving
Municipal  Obligations  which were not foreseen by the financial and  investment
communities. The Trust will take whatever action it considers appropriate in the
event of anticipated financial difficulties, default or bankruptcy of either the
issuer of any Municipal Obligation or of the underlying source of funds for debt
service.  Such action may include  retaining the services of various  persons or
firms  (including  affiliates  of the  Adviser)  to evaluate or protect any real
estate,  facilities or other assets  securing any such obligation or acquired by
the Trust as a result of any such  event,  and the  Trust  may also  manage  (or
engage  other  persons  to  manage)  or  otherwise  deal  with any real  estate,
facilities or other assets so acquired.  The Trust  anticipates that real estate
consulting  and  management  services may be required with respect to properties
securing various Municipal Obligations in its portfolio or subsequently acquired
by the Trust. The Trust will incur additional  expenditures in taking protective
action with respect to portfolio obligations in default and assets securing such
obligations.  To enforce  its rights in the event of a default in the payment of
interest or repayment of principal,  or both,  the Trust may take  possession of
and  manage  the assets or have a receiver  appointed  to collect  and  disburse
pledged revenues securing the issuer's obligations on such securities, which may
increase the operating  expenses and adversely affect the net asset value of the
Trust. Any income derived from the ownership of operation of such assets may not
be  tax-exempt.  In addition,  the Trust's  intention to qualify as a "regulated
investment  company"  ("RIC")  under the Code may limit the  extent to which the
Trust may exercise its rights by taking possession of such assets,  because as a
regulated investment company, the Trust is subject to certain limitations on its
investments and on the nature of its income.

      The yields on Municipal Obligations are dependent on a variety of factors,
including  purposes of issue and source of funds for  repayment,  general  money
market conditions,  general  conditions of the municipal bond market,  size of a
particular  offering,  maturity of the obligation  and rating of the issue.  The
ratings of Moody's,  S&P and Fitch represent their opinions as to the quality of
the Municipal Obligations which they undertake to rate. It should be emphasized,
however,  that ratings are based on judgment  and are not absolute  standards of
quality. Consequently,  Municipal Obligations with the same maturity, coupon and
rating may have  different  yields while  obligations  of the same  maturity and
coupon with different  ratings may have the same yield. In addition,  the market
price of Municipal  Obligations will normally fluctuate with changes in interest


                                      B-3
<PAGE>

rates,  and  therefore the net asset value of the Trust will be affected by such
changes.

      STATE CONCENTRATION.  The Trust may invest 25% or more of its total assets
in Municipal  Obligations of issuers  located in the same state.  When the Trust
does so, it will be sensitive to factors  affecting that state,  such as changes
in the economy,  decreases in tax collection or the tax base,  legislation which
limits taxes and changes in issuer credit ratings.

      ECONOMIC  SECTOR  CONCENTRATION.  The Trust may  invest 25% or more of its
total assets in Municipal  Obligations  of issuers in the same economic  sector.
There could be economic,  business or political  developments which might affect
all  Municipal  Obligations  in a particular  economic  sector.  In  particular,
investments in the industrial  revenue bonds listed above might involve (without
limitation) the following risks.

      Hospital bond ratings are often based on feasibility studies which contain
projections  of expenses,  revenues and occupancy  levels.  Among the influences
affecting a hospital's  gross  receipts and net income  available to service its
debt are demand for  hospital  services,  the ability of the hospital to provide
the services required,  management  capabilities,  economic  developments in the
service  area,  efforts by insurers and  government  agencies to limit rates and
expenses,  confidence  in the  hospital,  service  area  economic  developments,
competition,  availability  and expense of malpractice  insurance,  Medicaid and
Medicare funding and possible federal legislation limiting the rates of increase
of hospital charges.

      Electric utilities face problems in financing large construction  programs
in an  inflationary  period,  cost increases and delay  occasioned by safety and
environmental  considerations (particularly with respect to nuclear facilities),
difficulty in obtaining  fuel at reasonable  prices and in achieving  timely and
adequate rate relief from regulatory commissions, effects of energy conservation
and limitations on the capacity of the capital market to absorb utility debt.

      Bonds to finance life care  facilities  are  normally  secured only by the
revenues of each  facility and not by state or local  government  tax  payments,
they are  subject  to a wide  variety of risks.  Primarily,  the  projects  must
maintain adequate occupancy levels to be able to provide revenues  sufficient to
meet debt service payments.  Moreover,  since a portion of housing, medical care
and other services may be financed by an initial  deposit,  it is important that
the facility maintain adequate financial reserves to secure estimated  actuarial
liabilities.  The ability of management to accurately forecast inflationary cost
pressures is an important  factor in this process.  The  facilities  may also be
affected  adversely  by  regulatory  cost  restrictions  applied to health  care
delivery in general,  particularly  state regulations or changes in Medicare and
Medicaid  payments  or  qualifications,   or  restrictions  imposed  by  medical
insurance companies. They may also face competition from alternative health care
or conventional housing facilities in the private or public sector.

      MUNICIPAL   LEASES.   The  Trust  may  invest  in  municipal   leases  and
participations  therein,  which  arrangements  frequently involve special risks.
Municipal leases are obligations in the form of a lease or installment  purchase
arrangement  which is issued by state or local  governments to acquire equipment
and facilities.  Interest income from such  obligations is generally exempt from
local and state taxes in the state of issuance.  "Participations" in such leases
are  undivided  interests in a portion of the total  obligation.  Participations
entitle  their  holders to receive a pro rata  share of all  payments  under the
lease. The obligation of the issuer to meet its obligations under such leases is
often subject to the  appropriation by the appropriate  legislative  body, on an
annual or other basis, of funds for the payment of the obligations.  Investments
in municipal  leases are thus subject to the risk that the legislative body will
not make the  necessary  appropriation  and the  issuer  will not  otherwise  be


                                      B-4
<PAGE>

willing or able to meet its obligation.  Certain municipal lease obligations are
illiquid.

      WHEN-ISSUED SECURITIES.  New issues of Municipal Obligations are sometimes
offered  on a  "when-issued"  basis,  that  is,  delivery  and  payment  for the
securities  normally take place within a specified number of days after the date
of the  Trust's  commitment  and are subject to certain  conditions  such as the
issuance of satisfactory legal opinions.  The Trust may also purchase securities
on a when-issued  basis pursuant to refunding  contracts in connection  with the
refinancing  of  an  issuer's  outstanding  indebtedness.   Refunding  contracts
generally  require the issuer to sell and the Trust to buy such  securities on a
settlement date that could be several months or several years in the future. The
Trust may also purchase instruments that give the Trust the option to purchase a
Municipal Obligation when and if issued.

      The Trust will make  commitments to purchase  when-issued  securities only
with the  intention  of actually  acquiring  the  securities,  but may sell such
securities  before the settlement date if it is deemed  advisable as a matter of
investment  strategy.  The payment obligation and the interest rate that will be
received  on the  securities  are  fixed at the time the Trust  enters  into the
purchase  commitment.  When the  Trust  commits  to  purchase  a  security  on a
when-issued  basis it records  the  transaction  and  reflects  the value of the
security  in  determining  its  net  asset  value.  Securities  purchased  on  a
when-issued basis and the securities held by the Trust are subject to changes in
value  based  upon the  perception  of the  creditworthiness  of the  issuer and
changes in the level of interest  rates (I.E.  appreciation  when interest rates
decline and  depreciation  when interest rates rise).  Therefore,  to the extent
that the Trust remains substantially fully invested at the same time that it has
purchased  securities on a when-issued basis, there will be greater fluctuations
in the Trust's net asset value than if it set aside cash to pay for  when-issued
securities.

      REDEMPTION,  DEMAND AND PUT FEATURES AND PUT OPTIONS. Issuers of Municipal
Obligations  reserve the right to call (redeem) the bond.  If an issuer  redeems
securities  held by the Trust during a time of  declining  interest  rates,  the
Trust may not be able to reinvest the proceeds in securities  providing the same
investment return as the securities redeemed. Also, some bonds may have "put" or
"demand"  features that allow early  redemption by the  bondholder.  Longer term
fixed-rate  bonds may give the holder a right to request  redemption  at certain
times (often annually after the lapse of an intermediate  term). These bonds are
more  defensive  than  conventional  long term bonds because they may protect to
some degree against a rise in interest rates.

      LIQUIDITY  AND  PROTECTIVE  PUT  OPTIONS.  The Trust may also enter into a
separate  agreement with the seller of a security or some other person  granting
the Trust the  right to put the  security  to the  seller  thereof  or the other
person at an agreed  upon  price.  Such  agreements  are  subject to the risk of
default by the other  party,  although  the Trust  intends to limit this type of
transaction  to  institutions  (such as banks or securities  dealers)  which the
Adviser  believes  present minimal credit risks.  The Trust would engage in this
type of  transaction  to  facilitate  portfolio  liquidity  or (if the seller so
agrees) to hedge against rising interest rates.  There is no assurance that this
kind of put option will be available  to the Trust or that selling  institutions
will be willing to permit the Trust to  exercise a put to hedge  against  rising
interest  rates.  The Trust does not expect to assign any value to any  separate
put option which may be acquired to facilitate portfolio liquidity,  inasmuch as
the value (if any) of the put will be  reflected  in the value  assigned  to the
associated  security;  any put acquired for hedging  purposes would be valued in
good faith under methods or procedures  established by the Trustees of the Trust
after consideration of all relevant factors,  including its expiration date, the
price volatility of the associated  security,  the difference between the market
price  of the  associated  security  and the  exercise  price  of the  put,  the
creditworthiness  of the issuer of the put and the market  prices of  comparable


                                      B-5
<PAGE>

put options.  Interest  income  generated by certain  bonds having put or demand
features may be taxable.

      ILLIQUID  OBLIGATIONS.  At times,  a  substantial  portion of the  Trust's
assets  may be  invested  in  securities  as to which  the  Trust,  by itself or
together with other accounts managed by the Adviser and its affiliates,  holds a
major  portion  or all of such  securities.  Under  adverse  market or  economic
conditions or in the event of adverse changes in the financial  condition of the
issuer,  the Trust could find it more difficult to sell such securities when the
Adviser  believes it advisable  to do so or may be able to sell such  securities
only at prices lower than if such securities  were more widely held.  Under such
circumstances, it may also be more difficult to determine the fair value of such
securities for purposes of computing the Trust's net asset value.

      The secondary market for some Municipal  Obligations issued within a state
(including issues which are privately placed with the Trust) is less liquid than
that  for  taxable  debt  obligations  or other  more  widely  traded  Municipal
Obligations.  No  established  resale market exists for certain of the Municipal
Obligations  in which the Trust may  invest.  The market for  obligations  rated
below  investment  grade is also  likely to be less  liquid  than the market for
higher  rated  obligations.  As a result,  the Trust may be unable to dispose of
these  Municipal  Obligations at times when it would  otherwise wish to do so at
the prices at which they are valued.

      FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS.  A change in the level
of interest rates may affect the value of the  securities  held by the Trust (or
of securities  that the Trust expects to purchase).  To hedge against changes in
rates or as a  substitute  for the purchase of  securities,  the Trust may enter
into (i) futures  contracts for the purchase or sale of debt securities and (ii)
futures contracts on securities  indices.  All futures contracts entered into by
the Trust are  traded on  exchanges  or boards of trade  that are  licensed  and
regulated  by the  Commodity  Futures  Trading  Commission  ("CFTC") and must be
executed  through a futures  commission  merchant or  brokerage  firm which is a
member of the relevant  exchange.  The Trust may purchase and write call and put
options on  futures  contracts  which are  traded on a United  States or foreign
exchange  or board of trade.  The Trust will be  required,  in  connection  with
transactions in futures contracts and the writing of options on futures, to make
margin deposits,  which will be held by the Trust's custodian for the benefit of
the futures  commission  merchant through whom the Trust engages in such futures
and options transactions.

      Some  futures  contracts  and options  thereon may become  illiquid  under
adverse market conditions.  In addition,  during periods of market volatility, a
commodity  exchange  may  suspend or limit  transactions  in an  exchange-traded
instrument,  which may make the instrument temporarily illiquid and difficult to
price.  Commodity  exchanges may also establish  daily limits on the amount that
the price of a futures  contract  or futures  option can vary from the  previous
day's settlement price.  Once the daily limit is reached,  no trades may be made
that day at a price  beyond the limit.  This may prevent the Trust from  closing
out positions and limiting its losses.

      The Trust will engage in futures and related options transactions for bona
fide hedging purposes or non-hedging purposes as defined in or permitted by CFTC
regulations. The Trust will determine that the price fluctuations in the futures
contracts  and options on futures used for hedging  purposes  are  substantially
related  to  price  fluctuations  in  securities  held by the  Trust or which it
expects  to  purchase.  The Trust will  engage in  transactions  in futures  and
related options  contracts only to the extent such  transactions  are consistent
with the requirements of the Code for maintaining its qualification as a RIC for
federal income tax purposes.

      INVESTMENT  RESTRICTIONS.  The following  investment  restrictions  of the
Trust are  designated  as  fundamental  policies  and as such  cannot be changed
without the  approval  of the  holders of a majority of the Trust's  outstanding
voting  securities,  which as used in this  Statement of Additional  Information
means the lesser of (a) 67% of the shares of the Trust present or represented by
proxy at a meeting if the holders of more than 50% of the outstanding shares are
present or represented at the meeting or (b) more than 50% of outstanding shares
of the Trust. As a matter of fundamental policy the Trust may not:

            (1) Borrow money, except as permitted by the 1940 Act;

            (2) Issue senior securities,  as defined in the 1940 Act, other than
      (i)  preferred  shares which  immediately  after  issuance will have asset
      coverage of at least  200%,  (ii)  indebtedness  which  immediately  after
      issuance  will  have  asset  coverage  of at  least  300%,  or  (iii)  the
      borrowings permitted by investment restriction (1) above;

            (3)  Purchase  securities  on margin  (but the Trust may obtain such
      short-term  credits as may be necessary for the clearance of purchases and
      sales of securities).  The purchase of investment assets with the proceeds
      of a permitted  borrowing or securities  offering will not be deemed to be
      the purchase of securities on margin;

            (4) Underwrite securities issued by other persons, except insofar as
      it may technically be deemed to be an underwriter under the Securities Act
      of 1933 in selling or disposing of a portfolio investment;

            (5) Make loans to other  persons,  except by (a) the  acquisition of
      loan interests,  debt securities and other  obligations in which the Trust
      is authorized to invest in accordance  with its  investment  objective and
      policies,  (b) entering into  repurchase  agreements,  and (c) lending its
      portfolio securities;

            (6) Purchase or sell real estate,  although it may purchase and sell
      securities which are secured by interests in real estate and securities of
      issuers  which  invest  or deal in real  estate.  The Trust  reserves  the
      freedom of action to hold and to sell real estate  acquired as a result of
      the ownership of securities; or

            (7)  Purchase or sell  physical  commodities  or  contracts  for the
      purchase  or sale of physical  commodities.  Physical  commodities  do not
      include futures contracts with respect to securities,  securities  indices
      or other financial instruments.

            (8)  Invest  more than 25% of its  total  assets  in  securities  of
      issuers in any one industry.*

            *Securities   of   the   U.S.   Government,    its   agencies,    or
      instrumentalities, and securities, including Municipal Obligations, backed
      by the credit of a  governmental  entity are not  considered  to represent
      industries.  However,  Municipal Obligations backed only by the assets and
      revenues of  non-governmental  users may for this  purpose be deemed to be
      issued by such  non-governmental  users.  Thus, the 25%  limitation  would
      apply to such obligations.  As discussed previously in this section and in
      the Prospectus,  it is nonetheless  possible that the Fund may invest more
      than 25% of its total  assets in a broader  economic  sector of the market
      for Municipal  Obligations,  such as revenue  obligations of hospitals and
      other health care facilities or electrical  utility  revenue  obligations.
      The Fund  reserves  the  right to invest  more  than 25% of its  assets in
      industrial development bonds and private activity securities.



                                      B-7
<PAGE>

      For purposes of the Trust's investment restrictions,  the determination of
the "issuer" of a Municipal  Obligation  which is not a general  obligation bond
will  be  made  by the  Adviser  on the  basis  of  the  characteristics  of the
obligation  and other  relevant  factors,  the most  significant of which is the
source of funds  committed to meeting  interest and  principal  payments of such
obligation.

      The Trust has adopted the following nonfundamental investment policy which
may be changed by the Trustees without approval of the Trust's shareholders.  As
a matter  of  nonfundamental  policy,  the  Trust  may not make  short  sales of
securities  or  maintain  a short  position,  unless at all  times  when a short
position  is open it  either  owns an equal  amount of such  securities  or owns
securities  convertible  into or  exchangeable,  without  payment of any further
consideration,  for securities of the same issue as, and equal in amount to, the
securities sold short.

      Upon Board of Trustee  approval  the Trust may invest more than 10% of its
total assets in one or more other management investment companies (or may invest
in affiliated  investment companies) to the extent permitted by the 1940 Act and
rules thereunder.

      Whenever an investment  policy or investment  restriction set forth in the
Prospectus  or  this  Statement  of  Additional  Information  states  a  maximum
percentage  of assets  that may be  invested  in any  security or other asset or
describes a policy regarding quality  standards,  such percentage  limitation or
standard  shall be determined  immediately  after and as a result of the Trust's
acquisition  of such  security  or asset.  Accordingly,  any later  increase  or
decrease resulting from a change in values,  assets or other  circumstances will
not compel the Trust to dispose of such security or other asset. Notwithstanding
the  foregoing,  the Trust  must  always  be in  compliance  with the  borrowing
policies set forth above.

                              TRUSTEES AND OFFICERS

      The Trust's  Trustees and officers are listed below.  Except as indicated,

(1) Class I Trustee whose term expires in 1999.  
(2) Class II Trustee whose termexpires in 2000. 
(3) Class III Trustee whose term expires in 2001.

      Messrs. Hayes (Chairman),  Reamer and Thorndike are members of the Special
Committee  of the Board of  Trustees  of the Trust.  The  purpose of the Special
Committee is to consider, evaluate and make recommendations to the full Board of
Trustees  concerning (i) all contractual  arrangements with service providers to
the Trust,  including  investment  advisory,  administrative,  transfer  agency,
custodial and fund  accounting  and  distribution  services,  and (ii) all other
matters in which  Eaton  Vance or its  affiliates  has any  actual or  potential
conflict of interest with the Trust or its shareholders.

      The  Nominating  Committee  of the  Board  of  Trustees  of the  Trust  is
comprised  of four  Trustees  who are not  "interested  persons" as that term is
defined  under  the 1940  Act  ("noninterested  Trustees").  The  Committee  has
four-year  staggered  terms,  with one member  rotating off the  Committee to be
replaced by another  noninterested  Trustee.  The purpose of the Committee is to
recommend to the Board nominees for the position of noninterested Trustee and to
assure that at least a majority of the Board of Trustees is independent of Eaton
Vance and its affiliates.

      Messrs.  Treynor  (Chairman) and Dwight are members of the Audit Committee
of the Board of Trustees of the Trust. The Audit  Committee's  functions include
making   recommendations   to  the  Trustees  regarding  the  selection  of  the
independent  certified  public  accountants,  and reviewing  matters relative to
trading and brokerage policies and practices,  accounting and auditing practices
and  procedures,  accounting  records,  internal  accounting  controls,  and the
functions  performed by the custodian,  transfer  agent and dividend  disbursing
agent of the Trust.

      Trustees of the Trust who are not affiliated with the Adviser may elect to
defer receipt of all or a percentage of their annual fees in accordance with the
terms of a Trustees Deferred Compensation Plan (the "Trustees' Plan"). Under the
Trustees' Plan, an eligible Trustee may elect to have his deferred fees invested
by the Trust in the  shares of one or more  funds in the Eaton  Vance  Family of
Funds,  and the amount paid to the  Trustees  under the  Trustees'  Plan will be
determined based upon the performance of such investments. Deferral of Trustees'
fees in accordance with the Trustees' Plan will have a negligible  effect on the
Trust's assets, liabilities, and net income per share, and will not obligate the
Trust to retain the  services of any  Trustee or  obligate  the Trust to pay any
particular  level of  compensation  to the  Trustee.  The Trust  does not have a
retirement plan for its Trustees.

      The fees and expenses of the noninterested  Trustees of the Trust are paid
by the Trust.  (The  Trustees  of the Trust who are  members of the Eaton  Vance
organization  receive no  compensation  from the  Trust.)  During the year ended
December  31,  1997,  the  noninterested   Trustees  of  the  Trust  earned  the
compensation  set forth below in their  capacities as Trustees from the funds in
the Eaton Vance fund complex(1). It is estimated that the noninterested Trustees
will  receive  from the Trust the  amounts  set forth  below for the fiscal year
ending November 30, 1999.

                     INVESTMENT ADVISORY AND OTHER SERVICES

      Eaton  Vance,  its  affiliates  and its  predecessor  companies  have been
managing  assets of individuals  and  institutions  since 1924 and of investment
companies  since 1931.  They maintain a large staff of experienced  fixed-income
and equity investment  professionals to service the needs of their clients.  The
fixed-income  division  focuses  on all kinds of  taxable  investment-grade  and
high-yield  securities,  tax-exempt  investment-grade and high-yield securities,
and U.S. Government  securities.  The equity division covers stocks ranging from
blue chip to emerging  growth  companies.  Eaton Vance and its affiliates act as
adviser to a family of mutual funds,  and individual  and various  institutional
accounts,  including corporations,  hospitals,  retirement plans,  universities,
foundations and trusts.

      The  Trust  will be  responsible  for all of its costs  and  expenses  not
expressly  stated to be payable by Eaton Vance under the  Advisory  Agreement or
Administration  Agreement.  Such  costs  and  expenses  to be borne by the Trust
include,  without  limitation:  custody and transfer  agency fees and  expenses,
including those incurred for determining net asset value and keeping  accounting
books and records; expenses of pricing and valuation services; the cost of share
certificates;  membership dues in investment company organizations;  expenses of
acquiring,  holding and disposing of securities and other investments;  fees and
expenses of registering  under the securities  laws, stock exchange listing fees
and  governmental  fees;  rating  agency fees and  preferred  share  remarketing
expenses;  expenses  of  reports to  shareholders,  proxy  statements  and other
expenses of shareholders'  meetings;  insurance  premiums;  printing and mailing
expenses;  interest,  taxes and corporate fees;  legal and accounting  expenses;
compensation and expenses of Trustees not affiliated with Eaton Vance;  expenses
of conducting  repurchase  offers for the purpose of repurchasing  Trust shares;
and  investment  advisory  and  administration  fees.  The Trust  will also bear
expenses  incurred in  connection  with any  litigation  in which the Trust is a
party and any legal  obligation  to indemnify  its  officers  and Trustees  with
respect thereto, to the extent not covered by insurance.

      The Advisory  Agreement  with the Adviser  continues in effect to February
28, 2000 and from year to year so long as such  continuance is approved at least
annually  (i) by the vote of a majority  of the  noninterested  Trustees  of the
Trust or of the Adviser cast in person at a meeting  specifically called for the
purpose  of voting on such  approval  and (ii) by the Board of  Trustees  of the
Trust or by vote of a majority of the  outstanding  interests of the Trust.  The
Trust's  Administration  Agreement continues in effect from year to year so long


                                      B-11

as such  continuance  is approved at least annually by the vote of a majority of
the Trust's  Trustees.  Each  agreement  may be  terminated  at any time without
penalty on sixty (60) days' written notice by the Trustees of the Trust or Eaton
Vance, as applicable,  or by vote of the majority of the  outstanding  shares of
the Trust.  Each  agreement  will  terminate  automatically  in the event of its
assignment. Each agreement provides that, in the absence of willful misfeasance,
bad faith,  gross negligence or reckless  disregard of its obligations or duties
to the Trust under such agreements on the part of Eaton Vance, Eaton Vance shall
not be liable to the Trust for any loss  incurred,  to the extent not covered by
insurance.

      BMR and Eaton Vance are business trusts organized under Massachusetts law.
Eaton Vance,  Inc.  ("EV") serves as trustee of BMR and Eaton Vance.  BMR, Eaton
Vance and EV are wholly-owned subsidiaries of Eaton Vance Corporation ("EVC"), a
Maryland  corporation  and  publicly-held   holding  company.  EVC  through  its
subsidiaries  and  affiliates   engages  primarily  in  investment   management,
administration  and  marketing  activities.  The  Directors  of EVC are James B.
Hawkes,  Benjamin A. Rowland,  Jr., John G.L. Cabot, John M. Nelson,  Vincent M.
O'Reilly  and Ralph Z.  Sorenson.  All of the issued and  outstanding  shares of
Eaton Vance are owned by EVC.  All of the issued and  outstanding  shares of BMR
are owned by Eaton Vance.  All shares of the outstanding  Voting Common Stock of
EVC are  deposited in a Voting Trust,  the Voting  Trustees of which are Messrs.
Hawkes,  Rowland,  and Alan R. Dynner,  Thomas E. Faust,  Jr., Thomas J. Fetter,
Duncan Richardson, William M. Steul and Wharton P. Whitaker. The Voting Trustees
have unrestricted voting rights for the election of Directors of EVC. All of the
outstanding  voting trust  receipts  issued under said Voting Trust are owned by
certain  of the  officers  of BMR and  Eaton  Vance  who are also  officers,  or
officers  and  Directors  of EVC  and  EV.  As  indicated  under  "Trustees  and
Officers", all of the officers of the Trust (as well as Mr. Hawkes who is also a
Trustee) hold positions in the Eaton Vance organization.

      EVC and its  affiliates and their officers and employees from time to time
have transactions with various banks, including the custodian of the Trust, IBT.
It is Eaton Vance's  opinion that the terms and conditions of such  transactions
were not and will not be influenced by existing or potential  custodial or other
relationships between the Trust and such banks.


                                PORTFOLIO TRADING

      Decisions  concerning  the execution of portfolio  security  transactions,
including the selection of the market and the  executing  firm,  are made by the
Adviser.  The Adviser is also  responsible for the execution of transactions for
all other  accounts  managed by it. The Adviser  places the  portfolio  security
transactions of the Trust and of all other accounts  managed by it for execution
with many  firms.  The  Adviser  uses its best  efforts to obtain  execution  of
portfolio  security  transactions at prices which are  advantageous to the Trust
and at reasonably  competitive spreads or (when a disclosed  commission is being
charged) at reasonably  competitive commission rates. In seeking such execution,
the Adviser will use its best judgment in evaluating the terms of a transaction,
and will give  consideration  to various  relevant  factors,  including  without
limitation  the full range and quality of the  executing  firm's  services,  the
value of the brokerage and research services provided, the responsiveness of the
firm to the  Adviser,  the size  and type of the  transaction,  the  nature  and
character  of the  market  for the  security,  the  confidentiality,  speed  and
certainty  of effective  execution  required  for the  transaction,  the general
execution and  operational  capabilities  of the executing firm, the reputation,
reliability,  experience  and  financial  condition  of the firm,  the value and
quality of the services rendered by the firm in this and other transactions, and
the reasonableness of the spread or commission,  if any. Municipal  Obligations,
including  state  obligations,  purchased  and sold by the Trust  are  generally
traded in the over-the-counter  market on a net basis (i.e., without commission)
through  broker-dealers  and banks  acting for their own account  rather than as


                                      B-12
<PAGE>

brokers,  or otherwise  involve  transactions  directly  with the issuer of such
obligations.  Such firms attempt to profit from such  transactions  by buying at
the bid price and  selling  at the  higher  asked  price of the  market for such
obligations,  and the difference  between the bid and asked price is customarily
referred to as the spread.  The Trust may also  purchase  Municipal  Obligations
from underwriters,  and dealers in fixed price offerings,  the cost of which may
include undisclosed fees and concessions to the underwriters. On occasion it may
be necessary or appropriate  to purchase or sell a security  through a broker on
an agency  basis,  in which case the Trust will  incur a  brokerage  commission.
Although spreads or commissions on portfolio security  transactions will, in the
judgment of the Adviser,  be reasonable in relation to the value of the services
provided, spreads or commissions exceeding those which another firm might charge
may be paid to firms who were selected to execute  transactions on behalf of the
Trust and the  Adviser's  other  clients for  providing  brokerage  and research
services to the Adviser.

      As authorized in Section 28(e) of the  Securities  Exchange Act of 1934, a
broker or dealer who executes a portfolio transaction on behalf of the Trust may
receive a  commission  which is in excess of the  amount of  commission  another
broker or dealer  would have  charged  for  effecting  that  transaction  if the
Adviser  determines  in good  faith that such  compensation  was  reasonable  in
relation to the value of the  brokerage  and research  services  provided.  This
determination may be made on the basis of that particular  transaction or on the
basis of overall  responsibilities which the Adviser and its affiliates have for
accounts  over which they  exercise  investment  discretion.  In making any such
determination,  the Adviser will not attempt to place a specific dollar value on
the brokerage and research services provided or to determine what portion of the
commission  should be related to such services.  Brokerage and research services
may include advice as to the value of securities,  the advisability of investing
in,  purchasing,  or selling  securities,  and the availability of securities or
purchasers or sellers of securities;  furnishing analyses and reports concerning
issuers, industries, securities, economic factors and trends, portfolio strategy
and  the  performance  of  accounts;   effecting  securities   transactions  and
performing functions incidental thereto (such as clearance and settlement);  and
the "Research Services" referred to in the next paragraph.

      It is a common  practice of the  investment  advisory  industry and of the
Advisers of investment  companies,  institutions  and other investors to receive
research, analytical,  statistical and quotation services, data, information and
other  services,  products  and  materials  which  assist  such  advisers in the
performance of their  investment  responsibilities  ("Research  Services")  from
broker-dealer firms which execute portfolio transactions for the clients of such
advisers   and  from  third   parties  with  which  such   broker-dealers   have
arrangements.  Consistent  with this  practice,  the Adviser  receives  Research
Services from many broker-dealer firms with which the Adviser places the Trust's
transactions  and from  third  parties  with  which  these  broker-dealers  have
arrangements.  These Research Services include such matters as general economic,
political,  business  and market  information,  industry  and  company  reviews,
evaluations  of securities  and portfolio  strategies  and  transactions,  proxy
voting data and analysis services,  technical analysis of various aspects of the
securities market, recommendations as to the purchase and sale of securities and
other portfolio transactions,  financial, industry and trade publications,  news
and  information  services,  pricing and quotation  equipment and services,  and
research  oriented computer  hardware,  software,  data bases and services.  Any
particular  Research Service obtained through a broker-dealer may be used by the
Adviser in connection  with client  accounts other than those accounts which pay
commissions  to such  broker-dealer.  Any such  Research  Service may be broadly
useful and of value to the Adviser in rendering  investment advisory services to
all or a significant  portion of its clients,  or may be relevant and useful for
the management of only one client's  account or of a few clients'  accounts,  or
may be  useful  for the  management  of  merely a segment  of  certain  clients'
accounts, regardless of whether any such account or accounts paid commissions to
the broker-dealer through which such Research Service was obtained. The advisory
fee paid by the Trust is not reduced because the Adviser  receives such Research


                                      B-13
<PAGE>

Services.  The Adviser  evaluates the nature and quality of the various Research
Services  obtained  through   broker-dealer   firms  and  attempts  to  allocate
sufficient portfolio security transactions to such firms to ensure the continued
receipt of Research  Services which the Adviser  believes are useful or of value
to it in rendering investment advisory services to its clients.

      The  Trust  and the  Adviser  may  also  receive  Research  Services  from
underwriters and dealers in fixed-price  offerings,  which Research Services are
reviewed  and  evaluated  by the  Adviser  in  connection  with  its  investment
responsibilities.  The investment  companies sponsored by the Adviser or BMR may
allocate  trades  in such  offerings  to  acquire  information  relating  to the
performance,  fees and expenses of such companies and other mutual funds,  which
information  is  used  by the  Trustees  of  such  companies  to  fulfill  their
responsibility  to oversee  the  quality  of the  services  provided  by various
entities,  including the Adviser, to such companies. Such companies may also pay
cash for such information.

      Subject to the requirement  that the Adviser shall use its best efforts to
seek and execute portfolio security  transactions at advantageous  prices and at
reasonably competitive spreads or commission rates, the Adviser is authorized to
consider  as a factor  in the  selection  of any  broker-dealer  firm  with whom
portfolio  orders  may be placed  the fact that such firm has sold or is selling
shares of the Trust or of other investment  companies  sponsored by the Adviser.
This  policy is not  inconsistent  with a rule of the  National  Association  of
Securities Dealers,  Inc. ("NASD"),  which rule provides that no firm which is a
member of the NASD shall favor or  disfavor  the  distribution  of shares of any
particular  investment company or group of investment  companies on the basis of
brokerage commissions received or expected by such firm from any source.

      Municipal Obligations  considered as investments for the Trust may also be
appropriate  for  other  investment  accounts  managed  by  the  Adviser  or its
affiliates.  Whenever  decisions are made to buy or sell securities by the Trust
and one or more of such other accounts simultaneously, the Adviser will allocate
the security transactions (including "hot" issues) in a manner which it believes
to be equitable under the circumstances.  As a result of such allocations, there
may be instances where the Trust will not  participate in a transaction  that is
allocated  among  other  accounts.  If an  aggregated  order  cannot  be  filled
completely, allocations will generally be made on a pro rata basis. An order may
not be allocated on a pro rata basis where,  for example:  (i)  consideration is
given to  portfolio  managers  who  have  been  instrumental  in  developing  or
negotiating a particular  investment;  (ii) consideration is given to an account
with  specialized  investment  policies that coincide with the  particulars of a
specific  investment;  (iii) pro rata  allocation  would result in odd-lot or de
minimis  amounts being  allocated to a portfolio or other client;  or (iv) where
the Adviser  reasonably  determines that departure from a pro rata allocation is
advisable.  While  these  aggregation  and  allocation  policies  could  have  a
detrimental  effect on the price or amount of the  securities  available  to the
Trust from time to time, it is the opinion of the Trustees of the Trust that the
benefits  from the Adviser's  organization  outweigh any  disadvantage  that may
arise from exposure to simultaneous transactions.

                                      TAXES

      The Trust has  elected to be, and intends to qualify  for  treatment  each
year, as a RIC under the Code. Accordingly, the Trust intends to satisfy certain
requirements relating to sources of its income and diversification of its assets
and to distribute  substantially  all of its net  investment  income  (including
tax-exempt  income)  and  net  capital  gains  in  accordance  with  the  timing
requirements imposed by the Code, so as to maintain its RIC status. By doing so,
the  Trust  will  avoid  any  federal  income  tax on any  income  and  gains it
distributes to its shareholders. If the Trust failed to qualify as a RIC for any
taxable  year,  it would be taxed on the full amount of its  taxable  income for
that  year  without  being  able to  deduct  the  distributions  it makes to its
shareholders and the shareholders would treat all distributions, including those


                                      B-14
<PAGE>

that otherwise would qualify as "exempt-interest  dividends"  (described below),
as dividends  (that is, ordinary  income) to the extent of the Trusts'  earnings
and profits.

      To avoid  incurring  a federal  excise  tax  obligation,  the  Trust  must
distribute  (or be deemed to have  distributed)  each calendar year (i) at least
98% of its ordinary income (not including tax-exempt income) for that year, (ii)
at least 98% of its capital gain net income (which is the excess of its realized
capital gains over its realized capital losses), generally computed on the basis
of the one-year  period ending on November 30 of that year,  after  reduction by
any  available  capital  loss  carryforwards  and (iii)  100% of  certain  other
amounts.  Under  current  law,  provided  that the Trust  qualifies as a RIC, it
should not be liable for any income,  corporate  excise or franchise  tax in the
Commonwealth of Massachusetts.

      The Trust's  investment in zero coupon and certain other  securities  will
cause it to realize income prior to the receipt of cash payments with respect to
these  securities.  The Trust may be required to  liquidate  securities  that it
might otherwise have continued to hold in order to generate cash to enable it to
distribute that income to Trust  shareholders  and thereby remain  qualified for
treatment as a RIC and avoid imposition of the excise tax described above.

      Investments in lower-rated or unrated  securities may present  special tax
issues for the Trust to the extent that the issuers of these securities  default
on their  obligations  pertaining  thereto.  The federal tax law is not entirely
clear  regarding the  consequences  of the Trust's taking  certain  positions in
connection  with  ownership of  distressed  securities.  For  example,  there is
uncertainty regarding:  (i) when the Trust may or must cease to accrue interest,
original issue discount,  or market discount on these securities;  (ii) when and
to what extent  deductions  may be taken for bad debts or worthless  securities;
(iii) how  payments  received  on  obligations  in default  should be  allocated
between principal and income;  and (iv) whether exchanges of debt obligations in
a workout context are taxable.

      Distributions  by the Trust of net  tax-exempt  interest  income  that are
properly   designated  as   "exempt-interest   dividends"   may  be  treated  by
shareholders  as interest  excludable  from gross income under Section 103(a) of
the Code. For the Trust to be able to pay exempt-interest  dividends,  the Trust
must, and intends to, satisfy the requirement that, at the close of each quarter
of its taxable year,  at least 50% of the value of its total assets  consists of
obligations  the  interest on which is exempt from  regular  federal  income tax
under Code Section 103(a). The portion of exempt-interest dividends attributable
to interest on certain Municipal Obligations is treated as a tax preference item
for purposes of the AMT. Shareholders are required to report tax-exempt interest
dividends on their federal income tax returns.

      The Trust will  designate  distributions  made to holders of Common Shares
and to holders of those preferred shares,  including the APS, in accordance with
each  class's  proportionate  share  of  each  item of  Trust  income  (such  as
tax-exempt interest, net capital gains and other taxable income).

      A portion  of  exempt-interest  dividends  paid by the  Trust  will not be
tax-exempt to any  shareholder  who is a  "substantial  user" of the  facilities
financed by  tax-exempt  obligations  held by the Trust or "related  persons" of
such substantial users.

      Any recognized  gain or other income  attributable  to market  discount on
long-term  tax-exempt  Municipal  Obligations (i.e.,  obligations with a term of
more than one year) other than, in general,  at their original issue, is taxable
as ordinary  income.  Such an obligation  is generally  treated as acquired at a
market  discount if purchased  after its original issue at a price less than (i)
the stated  principal  amount payable at maturity,  in the case of an obligation
that does not have original issue discount, or (ii) in the case of an obligation
that does  have  original  issue  discount,  the sum of the issue  price and any
original  issue  discount  that accrued  before the  obligation  was  purchased,
subject to a de minimis exclusion.



                                      B-15
<PAGE>

      From time to time proposals have been  introduced  before Congress for the
purpose of  restricting  or  eliminating  the federal  income tax  exemption for
interest on certain types of Municipal Obligations,  and it can be expected that
similar  proposals may be introduced in the future.  If any such  proposals were
enacted,  the availability of Municipal  Obligations for investment by the Trust
and the value of the securities it held may be affected.

      The Trust may realize some capital  gains  (and/or  losses) as a result of
market  transactions,  including  sales of  portfolio  securities  and rights to
when-issued securities and options and futures transactions.  The Trust may also
realize taxable income from certain short-term taxable  obligations,  securities
loans,  a portion  of  discount  with  respect  to  certain  stripped  Municipal
Obligations  or their  stripped  coupons,  and certain  realized gains or income
attributable to accrued market discount. Any distributions by the Trust of those
capital gains or taxable income would be taxable to its  shareholders.  However,
it is expected that such amounts,  if any,  would normally be  insubstantial  in
relation to the tax-exempt interest earned by the Trust.  Certain  distributions
declared in October,  November or December and paid the following January may be
taxed to  shareholders  as if  received on December 31 of the year in which they
are declared.

      The Trust's  transactions in options and futures contracts will be subject
to special tax rules that may affect the amount,  timing and  character of Trust
distributions to shareholders.  For example, certain positions held by the Trust
on the last business day of each taxable year will be "marked to market"  (i.e.,
treated  as if  closed  out on that  day),  and any  resulting  gain or loss (in
addition  to gain or loss  from  actual  dispositions  of such  positions)  will
generally be treated as 60% long-term and 40%  short-term  capital gain or loss.
Certain positions held by the Trust that substantially diminish the Trust's risk
of loss  with  respect  to  other  positions  in its  portfolio  may  constitute
"straddles,"  which are  subject to tax rules that may cause  deferral  of Trust
losses,   adjustments  in  the  holding  period  of  portfolio  securities,  and
conversion of short-term capital losses into long-term capital losses. The Trust
may have to limit its  activities  in options and futures  contracts in order to
enable it to maintain its RIC status.

      Any  loss  realized  upon  the  sale  or  exchange  of the  APS  held by a
Shareholder  for  six  months  or less  will be  disallowed  to the  extent  the
shareholder has received exempt-interest dividends with respect to those shares,
and any such loss that  exceeds  the  disallowed  amount  will be  treated  as a
long-term  capital  loss to the extent of any  distribution  of net capital gain
with respect to those shares. In addition,  a loss realized on a sale of the APS
will be disallowed to the extent the  shareholder  acquires other APS within the
period beginning 30 days before the sale and ending 30 days after the sale.

      Taxable dividends  (including capital gain dividends) payable by the Trust
to  individuals  and  certain  other  non-corporate  shareholders  who  have not
provided the Trust with their correct taxpayer identification number ("TIN") and
certain certifications required by the Internal Revenue Service ("IRS"), as well
as   shareholders   with  respect  to  whom  the  Trust  has  received   certain
notifications from the IRS are subject to "backup" withholding of federal income
tax at a rate  of  31%.  An  individual's  TIN is  generally  his or her  social
security number.

      The Trust is not  appropriate  for  non-U.S.  investors or as a retirement
plan investment.

      STATE AND LOCAL TAXES. The exemption of interest income for federal income
tax purposes does not necessarily  result in exemption under the income or other
tax laws of any state or local taxing  authority.  Shareholders of the Trust may
be exempt from state and local taxes on  distributions  of  tax-exempt  interest
income derived from obligations of the state and/or  municipalities of the state
in which  they are  resident,  but  taxable  generally  on income  derived  from
obligations  of  other   jurisdictions.   The  Trust  will  report  annually  to


                                      B-16
<PAGE>

shareholders  the percentages  representing the  proportionate  ratio of its net
tax-exempt income earned in each state.

      The foregoing discussion does not address the special tax rules applicable
to certain  classes of  investors,  such as insurance  companies  and  financial
institutions. Shareholders should consult their own tax advisers with respect to
special tax rules that may apply in their particular situations,  as well as the
state or local tax consequences of investing in the Trust.

                                OTHER INFORMATION

      The  Trust  is  an   organization   of  the  type  commonly   known  as  a
"Massachusetts  business trust." Under Massachusetts law, Shareholders of such a
trust may, in certain  circumstances,  be held personally liable as partners for
the  obligations  of the trust.  The  Declaration  of Trust  contains an express
disclaimer of Shareholder liability in connection with the Trust property or the
acts,  obligations  or  affairs  of the  Trust.  The  Declaration  of Trust also
provides for  indemnification  out of the Trust property of any Shareholder held
personally  liable for the claims and  liabilities  to which a  Shareholder  may
become subject by reason of being or having been a  Shareholder.  Thus, the risk
of a Shareholder incurring financial loss on account of Shareholder liability is
limited  to  circumstances  in which  the  Trust  itself  is  unable to meet its
obligations. The Trust believes the risk of any Shareholder of APS incurring any
liability for the obligations of the Trust is remote.

      The Declaration of Trust provides that the Trustees will not be liable for
errors of judgment or mistakes of fact or law; but nothing in the Declaration of
Trust protects a Trustee against any liability to the Trust or its  shareholders
to which he would  otherwise  be subject by reason of willful  misfeasance,  bad
faith,  gross  negligence,  or reckless  disregard of the duties involved in the
conduct of his office.  Voting rights are not  cumulative,  which means that the
holders of more than 50% of the shares  voting for the  election of Trustees can
elect 100% of the Trustees and, in such event, the holders of the remaining less
than 50% of the  shares  voting  on the  matter  will  not be able to elect  any
Trustees.

      The  Declaration of Trust provides that no person shall serve as a Trustee
if shareholders  holding  two-thirds of the outstanding  shares have removed him
from  that  office  either  by a  written  declaration  filed  with the  Trust's
custodian or by votes cast at a meeting called for that purpose. The Declaration
of Trust further  provides that the Trustees of the Trust shall  promptly call a
meeting of the shareholders for the purpose of voting upon a question of removal
of any such Trustee or Trustees when requested in writing so to do by the record
holders of not less than 10 per centum of the outstanding shares.

      The Trust's Prospectus and this Statement of Additional Information do not
contain all of the information set forth in the Registration  Statement that the
Fund has filed with the SEC. The complete Registration Statement may be obtained
from the SEC upon payment of the fee prescribed by its Rules and Regulations.

                          INDEPENDENT AUDITORS' REPORT


To the Trustees and Shareholder of
Eaton Vance Municipal Income Trust:


      We have audited the  accompanying  statement of assets and  liabilities of
Eaton Vance Municipal Income Trust (the "Fund") as of                    ,  1999
and  the  related   statement  of  operations   for  the  _______  period  ended
                     ,  1999. These financial  statements are the responsibility
of the Fund's  management.  Our responsibility is to express an opinion on these
financial statements based on our audit.

      We conducted  our audit in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

      In our  opinion,  such  financial  statements  referred to above  presents
fairly,  in all  material  respects,  the  financial  position  of  Eaton  Vance
Municipal  Income Trust as of , 1999,  and the results of its operations for the
stated period, in conformity with generally accepted accounting principles.

                           RATINGS OF MUNICIPAL BONDS
                 DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.
                       ("MOODY'S") MUNICIPAL BOND RATINGS

 Aaa  Bonds which are rated Aaa are judged to be of the best quality. They carry
      the smallest  degree of investment  risk and are generally  referred to as
      "gilt  edge."  Interest  payments  are  protected  by a  large  or  by  an
      exceptionally  stable  margin and  principal is secure.  While the various
      protective  elements  are  likely  to  change,  such  changes  as  can  be
      visualized are most unlikely to impair the Trustamentally  strong position
      of such issues.
 Aa   Bonds  which  are  rated  Aa  are  judged  to be of  high  quality  by all
      standards.  Together  with the Aaa group they  comprise what are generally
      known as high  grade  bonds.  They are  rated  lower  than the best  bonds
      because  margins of protection may not be as large as in Aaa securities or
      fluctuation  of protective  elements may be of greater  amplitude or there
      may be other  elements  present  which make the long-  term  risks  appear
      somewhat larger than in Aaa securities.
 A    Bonds which are rated A possess many favorable  investment  attributes and
      are to be considered  as upper medium grade  obligations.  Factors  giving
      security to principal and interest are considered  adequate,  but elements
      may be present which suggest a  susceptibility  to impairment  sometime in
      the future.
 Baa  Bonds  which are rated Baa are  considered  as medium  grade  obligations,
      i.e.,  they are neither  highly  protected  nor poorly  secured.  Interest
      payment and principal security appear adequate for the present but certain
      protective elements may be lacking or may be characteristically unreliable
      over any great  length of time.  Such  bonds lack  outstanding  investment
      characteristics and in fact have speculative characteristics as well.
 Ba   Bonds which are rated Ba are judged to have  speculative  elements;  their
      future  cannot be  considered  as well  assured.  Often the  protection of
      interest and principal  payments may be very moderate and thereby not well
      safeguarded during both good and bad times over the future. Uncertainty of
      position characterizes bonds in this class.
 B    Bonds which are rated B generally  lack  characteristics  of the desirable
      investment. Assurance of interest and principal payments or of maintenance
      of other terms of the contract over any long period of time may be small.
 Caa  Bonds  which are rated Caa are of poor  standing.  Such  issues  may be in
      default  or there may be  present  elements  of  danger  with  respect  to
      principal or interest.
 Ca   Bonds which are rated Ca represent  obligations which are speculative in a
      high  degree.  Such  issues  are often in  default  or have  other  marked
      shortcomings.
 C    Bonds which are rated C are the lowest rated class of bonds, and issues so
      rated can be regarded as having extremely poor prospects of ever attaining
      any real investment standing.

      Note:  Those bonds in the Aa, A, Baa, Ba and B  categories  which  Moody's
believes  possess the strongest  credit  attributes  within those categories are
designated by the symbols Aa1, A1, Baa1, Ba1 and B1.

      Short-term Notes: The four ratings of Moody's for short-term notes are MIG
1/VMIG1,  MIG 2/VMIG2,  MIG 3/VMIG3 and MIG 4/VMIG4;  MIG 1/VMIG1  denotes "best
quality . . . strong protection by established cash flows";  MIG 2/VMIG2 denotes
"high  quality"  with ample  margins of  protection;  MIG  3/VMIG3  notes are of
"favorable  quality  . . . but . . .  lacking  the  undeniable  strength  of the


                                      B-22

preceding grades"; MIG 4/VMIG4 notes are of "adequate quality . . . [p]rotection
commonly  regarded as required of an investment  security is present . . . there
is specific risk."

                      DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS

      Moody's Commercial Paper ratings are opinions of the ability of issuers to
repay  punctually  promissory  obligations  not having an  original  maturity in
excess of nine months.  Moody's  employs the following three  designations,  all
judged to be investment  grade,  to indicate the relative  repayment  ability of
rated issuers:

      Issuers rated Prime-1 (or related supporting institutions) have a superior
ability for repayment of short-term  promissory  obligations.  Prime-1 repayment
ability will often be evidenced by the following characteristics: leading market
positions  in well  established  industries;  high  rates of  return  on  Trusts
employed;  conservative  capitalization structure with moderate reliance on debt
and ample asset protection; broad margins in earning coverage of fixed financial
charges and high  internal cash  generation;  and well  established  access to a
range of financial markets and assured sources of alternate liquidity.

      Issuers rated Prime-2 (or related  supporting  institutions) have a strong
ability for repayment of short-term promissory  obligations.  This will normally
be evidenced by many of the characteristics  cited above but to a lesser degree.
Earnings  trends  and  coverage  ratios,  while  sound,  may be more  subject to
variation. Capitalization characteristics,  while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

      Issuers  rated  Prime-3 (or  supporting  institutions)  have an acceptable
ability  for  repayment  of  short-term  promissory  obligations.  The effect of
industry   characteristics  and  market  composition  may  be  more  pronounced.
Variability in earnings and  profitability may result in changes in the level of
debt protection measurements and may require relatively high financial leverage.
Adequate alternate liquidity is maintained.

      Issuers  rated  Not  Prime  do not fall  within  any of the  Prime  rating
categories.

DESCRIPTION OF STANDARD & POOR'S, A DIVISION OF THE MCGRAW-HILL COMPANIES,  INC.
("STANDARD & POOR'S"), MUNICIPAL DEBT RATINGS

      A  Standard  & Poor's  issue  credit  rating is a current  opinion  of the
creditworthiness of an obligor with respect to a specific financial  obligation,
a specific class of financial  obligations,  or a specific financial program. It
takes into consideration the  creditworthiness of guarantors,  insurers or other
forms of credit enhancement on the obligation.

      The issue credit rating is not a recommendation to purchase,  sell or hold
a financial  obligation,  inasmuch as it does not comment as to market  price or
suitability for a particular investor.

      The ratings are based on current information  furnished by the obligors or
obtained by Standard & Poor's from other sources it considers reliable. Standard
& Poor's  does not  perform an audit in  connection  with any rating and may, on
occasion,  rely on unaudited financial information.  The ratings may be changed,
suspended  or withdrawn  as a result of changes in, or  unavailability  of, such
information, or based on other circumstances.

      The   ratings   are  based,   in  varying   degrees,   on  the   following
considerations:



                                      B-23
<PAGE>

      I.    Likelihood of  payment-capacity  and  willingness  of the obligor to
            meet its financial  commitment  on an obligation in accordance  with
            the terms of obligation;

      II.   Nature of and provisions of the obligation; and

      III.  Protection  afforded by, and relative position of, the obligation in
            the event of bankruptcy,  reorganization  or other arrangement under
            the laws of bankruptcy and other laws affecting creditors' rights.

      AAA   Debt rated  "AAA" has the  highest  rating  assigned  by  Standard &
            Poor's. The obligor's  capacity to meet its financial  commitment on
            the obligation is extremely strong.

      AA    Debt rated "AA" differs from the highest rated  obligations  only in
            small  degree.   The  obligor's   capacity  to  meet  its  financial
            commitment on the obligation is very strong.

      A     Debt rated "A" is somewhat more  susceptible to the adverse  effects
            of changes in  circumstances  and economic  conditions  than debt in
            higher-rated categories. However, the obligor's capacity to meet its
            financial commitment on the obligation is still strong.

      BBB   Debt rated "BBB" exhibits adequate protection  parameters.  However,
            adverse  economic  conditions  or  changing  circumstances  are more
            likely to lead to a  weakened  capacity  of the  obligor to meet its
            financial commitment to the obligation.

      BB    Debt rated "BB," "B," "CCC," "CC" and "C" is regarded as having
      B     significant speculative characteristics. "BB" indicates the
      CCC   least degree of speculation and "C" the highest degree of
      CC    speculation. While such bonds will likely have some quality and
      C     protective  characteristics,  these  may be  outweighed  by large
            uncertainties or major exposures to adverse conditions.

      D     Debt rated "D" is in payment  default.  The "D" rating  category  is
            used when  payments  on an  obligation  are not made on the date due
            even if the applicable grace period has not expired, unless Standard
            & Poor's  believes that such payments will be made during such grace
            period.  The "D"  rating  also  will be used  upon the  filing  of a
            bankruptcy petition or the taking of a similar action if payments on
            an obligation are jeopardized.

      Plus (+) or Minus (-):  The ratings  from "AA" to "CCC" may be modified by
the addition of a plus or minus sign to show relative  standing within the major
rating categories.

                 DESCRIPTION OF STANDARD & POOR'S COMMERCIAL PAPER RATINGS

      A Standard & Poor's Commercial Paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. Ratings are graded into several categories, ranging from "A-1" for the
highest-quality  obligations  to "D" for the  lowest.  These  categories  are as
follows:

A-1   This highest category indicates that the degree of safety regarding timely
      payment is strong.  Those issues  determined to possess  extremely  strong
      safety characteristics are denoted with a plus sign (+) designation.



                                      B-24
<PAGE>

A-2   Capacity  for  timely   payment  on  issues  with  this   designation   is
      satisfactory. However, the relative degree of safety is not as high as for
      issues designated "A-1".

A-3   Issues  carrying  this  designation  have an adequate  capacity for timely
      payment.  They are,  however,  more  vulnerable to the adverse  effects of
      changes   in   circumstances   than   obligations   carrying   the  higher
      designations.

B     Issues  rated "B" are  regarded as having only  speculative  capacity  for
      timely payment.

C     This rating is assigned to  short-term  debt  obligations  with a doubtful
      capacity for payment.

D     Debt rated "D" is in payment default. The "D" rating category is used when
      interest payments or principal payments are not made on the date due, even
      if the applicable  grace period has not expired,  unless Standard & Poor's
      believes that such payments will be made during such grace period.

      A Commercial  Paper rating is not a  recommendation  to purchase or sell a
security.  The ratings are based on current information  furnished to Standard &
Poor's by the issuer or  obtained  by  Standard & Poor's  from other  sources it
considers  reliable.  The ratings may be changed,  suspended,  or withdrawn as a
result of changes in, or unavailability of, such information.

        DESCRIPTION OF STANDARD & POOR'S SHORT-TERM ISSUED CREDIT RATINGS

      A Standard & Poor's note rating reflects the liquidity  factors and market
access  risks  unique to notes.  Notes  due in three  years or less will  likely
receive a note  rating.  Notes  maturing  beyond  three  years will most  likely
receive a long-term debt rating.  The following  criteria will be used in making
that assessment.

      --Amortization  schedule--the  larger the final maturity relative to other
maturities, the more likely it will be treated as a note.

      --Source of payment--the more dependent the issue is on the market for its
refinancing, the more likely it will be treated as a note.

      Note rating symbols are as follows:

      SP-1  Strong capacity to pay principal and interest.  An issue  determined
            to possess a very  strong  capacity  to pay debt  service is given a
            plus "+" designation.

      SP-2  Satisfactory  capacity  to pay  principal  and  interest,  with some
            vulnerability  to adverse  financial  and economic  changes over the
            term of the notes.

      SP-3 Speculative capacity to pay principal and interest.



                                      B-25

     DESCRIPTION OF FITCH IBCA, INC. ("FITCH") INVESTMENT GRADE BOND RATINGS

      Fitch  investment  grade  bond  ratings  provide a guide to  investors  in
determining the credit risk associated  with a particular  security.  The rating
represents Fitch's assessment of the issuer's ability to meet the obligations of
a specific debt issue or class of debt in a timely manner.

      The rating takes into  consideration  special  features of the issue,  its
relationship  to other  obligations of the issuer,  the current and  prospective
financial  condition and operating  performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength and credit quality.

      Fitch ratings do not reflect any credit  enhancement  that may be provided
by insurance policies or financial guarantees unless otherwise indicated.

      Bonds  carrying  the  same  rating  are of  similar  but  not  necessarily
identical credit quality since the rating  categories do not fully reflect small
differences in the degrees of credit risk.

      Fitch ratings are not  recommendations to buy, sell, or hold any security.
Ratings do not comment on the adequacy of market price,  the  suitability of any
security for a particular  investor,  or the tax-exempt  nature or taxability of
payments made in respect of any security.

      Fitch  ratings  are based on  information  obtained  from  issuers,  other
obligors,  underwriters,  their experts,  and other sources Fitch believes to be
reliable.  Fitch  does not  audit  or  verify  the  truth  or  accuracy  of such
information.  Ratings may be changed,  suspended,  or  withdrawn  as a result of
changes in, or the unavailability of, information or for other reasons.

      AAA   Bonds  considered to be investment  grade and of the highest  credit
            quality.  The obligor  has an  exceptionally  strong  ability to pay
            interest  and repay  principal,  which is unlikely to be affected by
            reasonably foreseeable events.

      AA    Bonds  considered  to be  investment  grade and of very high  credit
            quality.  The obligor's  ability to pay interest and repay principal
            is very  strong,  although not quite as strong as bonds rated "AAA."
            Because  bonds  rated  in the  "AAA"  and  "AA"  categories  are not
            significantly vulnerable to foreseeable future developments,  short-
            term debt of these issuers is generally rated "F-1+."

      A     Bonds  considered to be investment grade and of high credit quality.
            The  obligor's  ability  to pay  interest  and  repay  principal  is
            considered  to be  strong,  but may be more  vulnerable  to  adverse
            changes in economic  conditions  and  circumstances  than bonds with
            higher ratings.

      BBB   Bonds considered to be investment  grade and of  satisfactory-credit
            quality.  The obligor's  ability to pay interest and repay principal
            is considered to be adequate. Adverse changes in economic conditions
            and circumstances,  however,  are more likely to have adverse impact
            on these bonds, and therefore impair timely payment.  The likelihood
            that the ratings of these bonds will fall below  investment grade is
            higher than for bonds with higher ratings.

      Plus (+) or Minus (-):  Plus and minus signs are used with a rating symbol
to indicate the relative  position of a credit within the rating category.  Plus
and minus signs, however, are not used in the "AAA" category.



                                      B-26
<PAGE>

NR          Indicates that Fitch does not rate the specific issue.

Conditional A conditional  rating is premised on the successful  completion of a
            project or the occurrence of a specific event.

Suspended   A rating is  suspended  when Fitch  deems the amount of  information
            available from the issuer to be inadequate for rating purposes.

Withdrawn   A rating  will be  withdrawn  when an issue  matures or is called or
            refinanced  and,  at  Fitch's  discretion,  when an issuer  fails to
            furnish proper and timely information.

FitchAlert  Ratings  are  placed  on  FitchAlert  to  notify   investors  of  an
            occurrence  that is  likely to  result  in a rating  change  and the
            likely direction of such change. These are designated as "Positive,"
            indicating a potential upgrade, "Negative," for potential downgrade,
            or "Evolving," where ratings may be raised or lowered. FitchAlert is
            relatively short-term, and should be resolved within 12 months.

      Ratings Outlook:  An outlook is used to describe the most likely direction
of any rating change over the  intermediate  term. It is described as "Positive"
or "Negative." The absence of a designation indicates a stable outlook.

DESCRIPTION OF FITCH'S SPECULATIVE GRADE BOND RATINGS

      Fitch  speculative  grade bond  ratings  provide a guide to  investors  in
determining the credit risk associated with a particular  security.  The ratings
("BB" to "C") represent  Fitch's  assessment of the likelihood of timely payment
of principal  and interest in accordance  with the terms of obligation  for bond
issues not in default.  For  defaulted  bonds,  the rating  ("DDD" to "D") is an
assessment of the ultimate recovery value through reorganization or liquidation.

      The rating takes into  consideration  special  features of the issue,  its
relationship  to other  obligations of the issuer,  the current and  prospective
financial  condition and operating  performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength.

      Bonds that have the rating are of similar  but not  necessarily  identical
credit quality since rating  categories  cannot fully reflect the differences in
degrees of credit risk.

      BB    Bonds are  considered  speculative.  The  obligor's  ability  to pay
            interest and repay  principal  may be affected  over time by adverse
            economic changes.  However,  business and financial alternatives can
            be identified  which could assist the obligor in satisfying its debt
            service requirements.

      B     Bonds are considered highly  speculative.  While bonds in this class
            are currently meeting debt service requirements,  the probability of
            continued  timely  payment of principal  and  interest  reflects the
            obligor's  limited  margin  of  safety  and the need for  reasonable
            business and economic activity throughout the life of the issue.

      CCC   Bonds  have  certain  identifiable  characteristics  which,  if  not
            remedied,  may lead to  default.  The  ability  to meet  obligations
            requires an advantageous business and economic environment.



                                      B-27
<PAGE>

    CC    Bonds are minimally protected. Default in payment of interest and/or
          principal seems probable over time.

    C     Bonds are in imminent default in payment of interest or principal.

    DDD   Bonds are in default on interest and/or principal payments. Such bonds
    DD    are extremely speculative and should be valued on the basis of
          their D ultimate  recovery value in liquidation or reorganization of
    the obligor.  "DDD" represents the highest potential for recovery on these
    bonds, and "D" represents the lowest potential for recovery.

      Plus (+) or Minus (-):  Plus and minus signs are used with a rating symbol
to indicate the relative  position of a credit within the rating category.  Plus
and minus signs, however, are not used in the "DDD," "DD," or "D" categories.

                    DESCRIPTION OF FITCH'S SHORT-TERM RATINGS

      Fitch's  short-term  ratings apply to debt obligations that are payable on
demand or have original  maturities of up to three years,  including  commercial
paper, certificates of deposit,  medium-term notes, and municipal and investment
notes.

      The short-term  rating places greater  emphasis than a long-term rating on
the  existence of liquidity  necessary  to meet the  issuer's  obligations  in a
timely manner.

      Fitch short-term ratings are as follows:

F-1+  Exceptionally  Strong  Credit  Quality.  Issues  assigned  this rating are
      regarded as having the strongest degree of assurance for timely payment.

F-1   Very  Strong  Credit  Quality.  Issues  assigned  this  rating  reflect an
      assurance of timely payment only slightly less in degree than issues rated
      "F-1+."

F-2   Good Credit  Quality.  Issues  assigned  this  rating have a  satisfactory
      degree of assurance for timely payment, but the margin of safety is not as
      great as for issues assigned "F-1+" and "F-1" ratings.

F-3   Fair Credit  Quality.  Issues  assigned  this rating have  characteristics
      suggesting  that the degree of assurance  for timely  payment is adequate;
      however,  near-term  adverse  changes  could cause these  securities to be
      rated below in investment grade.

F-S   Weak Credit  Quality.  Issues  assigned  this rating have  characteristics
      suggesting  a minimal  degree of  assurance  for  timely  payment  and are
      vulnerable  to  near-term   adverse  changes  in  financial  and  economic
      conditions.

D     Default.  Issues  assigned  this rating are in actual or imminent  payment
      default.

LOC   The symbol "LOC"  indicates that the rating is based on a letter of credit
      issued by a commercial bank.

                           TAX EQUIVALENT YIELD TABLE

      The table below gives the approximate  yield a taxable  security must earn
at various income brackets to produce  after-tax  yields  equivalent to those of
tax-exempt bonds yielding from 4% to 6% under the regular federal income tax law
and tax rates applicable to individuals for 1998.

*NET  AMOUNT  SUBJECT TO FEDERAL  AND  MASSACHUSETTS  PERSONAL  INCOME TAX AFTER
DEDUCTIONS AND EXEMPTIONS.

      The above  indicated  federal income tax brackets do not take into account
the effect of a  reduction  in the  deductibility  of  itemized  deductions  for
individual  taxpayers with adjusted gross income in excess of $124,500.  The tax
brackets  also do not show the effects of phaseout  of personal  exemptions  for
single filers with adjusted  gross income in excess of $124,500 and joint filers
with adjusted gross income in excess of $186,800. The effective tax brackets and
equivalent taxable yields of those taxpayers will be higher than those indicated
above.

      Yields  shown  are for  illustration  purposes  only and are not  meant to
represent  the Trust's  actual  yield.  No assurance can be given that the Trust
will achieve any specific  tax-exempt yield. While it is expected that the Trust
will invest  principally in  obligations  the interest from which is exempt from
the  regular  federal  income  tax,  other  income  received by the Trust may be
taxable.  The table does not take into  account  state or local  taxes,  if any,
payable on Trust distributions. It should also be noted that the interest earned
on certain  "private  activity  bonds",  while  exempt from the regular  federal
income  tax,  is  treated  as a tax  preference  item which  could  subject  the
recipient to the AMT. The  illustrations  assume that the AMT is not  applicable
and do not take into account any tax credits that may be available.

      The  information  set forth above is as of the date of this  Statement  of
Additional  Information.  Subsequent tax law changes could result in prospective
or retroactive changes in the tax brackets, tax rates, and tax-equivalent yields
set forth  above.  Investors  should  consult  their tax adviser for  additional
information.

                              SETTLEMENT PROCEDURES

      The following  summary of Settlement  Procedures sets forth the procedures
expected to be followed in  connection  with the  settlement of each Auction and
will be  incorporated  by  reference  in the Auction  Agent  Agreement  and each
Broker-Dealer  Agreement.  Nothing  contained in this  Appendix B  constitutes a
representation  by the Trust that in each Auction each party  referred to herein
actually will perform the  procedures  described  herein to be performed by such
party.  Capitalized  terms  used  herein  shall  have  the  respective  meanings
specified in the glossary of this  Prospectus or Appendix C hereto,  as the case
may be.

      (a) On each Auction  Date,  the Auction Agent shall notify by telephone or
through  the  Auction  Agent's   Processing  System  the   Broker-Dealers   that

          (ii) whether Sufficient Clearing Bids existed for the determination of
      the Applicable Rate;

          (iii) if such Broker-Dealer (a "Seller's  Broker-Dealer")  submitted a
      Bid or a Sell Order on behalf of a Beneficial Owner, the number of shares,

          (iv) if such Broker-Dealer (a "Buyer's Broker-Dealer") submitted a Bid
      on behalf of a Potential  Beneficial  Owner, the number of shares, if any,
      of APS to be purchased by such Potential Beneficial Owner;

          (v) if the  aggregate  number  of  shares  of  APS to be  sold  by all
      Beneficial Owners on whose behalf such Broker-Dealer  submitted a Bid or a
      Sell Order exceeds the  aggregate  number of shares of APS to be purchased
      by all  Potential  Beneficial  Owners on whose  behalf such  Broker-Dealer
      submitted a Bid, the name or names of one or more  Buyer's  Broker-Dealers
      (and the name of the Agent  Member,  if any, of each such Buyer's  Broker-
      Dealer) acting for one or more  purchasers of such excess number of shares
      of APS and the  number  of such  shares to be  purchased  from one or more
      Beneficial Owners on whose behalf such Broker-Dealer  acted by one or more
      Potential   Beneficial  Owners  on  whose  behalf  each  of  such  Buyer's
      Broker-Dealers acted;

          (vi) if the  aggregate  number of shares of APS to be purchased by all
      Potential Beneficial Owners on whose behalf such Broker-Dealer submitted a
      Bid  exceeds  the  aggregate  number  of  shares  of APS to be sold by all
      Beneficial Owners on whose behalf such Broker-Dealer  submitted a Bid or a
      Sell Order, the name or names of one or more Seller's  Broker-Dealers (and
      the name of the Agent Member, if any, of each such Seller's Broker-Dealer)
      acting for one or more sellers of such excess  number of shares of APS and
      the number of such shares to be sold to one or more  Potential  Beneficial
      Owners on whose behalf such Broker-Dealer  acted by one or more Beneficial
      Owners on whose behalf each of such Seller's Broker-Dealers acted; and

          (vii) the Auction Date of the next succeeding  Auction with respect to
      the APS.

          (b) On each Auction Date, each  Broker-Dealer  that submitted an Order
      on behalf of any Beneficial Owner or Potential Beneficial Owner shall:

          (i) in the case of a  Broker-Dealer  that is a Buyer's  Broker-Dealer,
      instruct   each   Potential   Beneficial   Owner  on  whose   behalf  such
      Broker-Dealer  submitted a Bid that was accepted,  in whole or in part, to
      instruct  such  Potential  Beneficial  Owner's Agent Member to pay to such
      Broker-Dealer (or its Agent Member) through the Securities  Depository the
      amount  necessary  to purchase the number of shares of APS to be purchased
      pursuant  to such Bid  against  receipt of such  shares  and  advise  such
      Potential  Beneficial Owner of the Applicable Rate for the next succeeding
      Dividend Period;

      instruct  each  Beneficial  Owner  on  whose  behalf  such   Broker-Dealer
      submitted a Sell Order that was  accepted,  in whole or in part,  or a Bid
      that  was  accepted,  in whole or in part,  to  instruct  such  Beneficial
      Owner's  Agent  Member  to  deliver  to such  Broker-Dealer  (or its Agent
      Member)  through the Securities  Depository the number of shares of APS to
      be sold  pursuant to such Order  against  payment  therefor and advise any
      such  Beneficial  Owner that will  continue  to hold  shares of APS of the
      Applicable Rate for the next succeeding Dividend Period;

          (iii) advise each Beneficial Owner on whose behalf such  Broker-Dealer
      submitted  a Hold  Order of the  Applicable  Rate for the next  succeeding
      Dividend Period;

          (iv) advise each Beneficial  Owner on whose behalf such  Broker-Dealer
      submitted  an Order of the Auction Date for the next  succeeding  Auction;
      and

          (v)  advise  each  Potential  Beneficial  Owner on whose  behalf  such
      Broker- Dealer submitted a Bid that was accepted,  in whole or in part, of
      the Auction Date for the next succeeding Auction.

          (c) On the basis of the  information  provided  to it  pursuant to (a)
      above, each  Broker-Dealer  that submitted a Bid or a Sell Order on behalf
      of a Potential  Beneficial  Owner or a  Beneficial  Owner  shall,  in such
      manner  and at  such  time  or  times  as in its  sole  discretion  it may
      determine,  allocate  any Trusts  received by it pursuant to (b) (i) above
      and any shares of APS  received by it pursuant to (b) (ii) above among the
      Potential  Beneficial  Owners, if any, on whose behalf such  Broker-Dealer
      submitted  Bids,  the  Beneficial  Owners,  if any,  on whose  behalf such
      Broker-Dealer  submitted  Bids that were accepted or Sell Orders,  and any
      Broker-Dealer  or  Broker-Dealers  identified  to it by the Auction  Agent
      pursuant to (a) (v) or (a)(vi) above.

          (d) On each Auction Date:

          (i)  each  Potential  Beneficial  Owner  and  Beneficial  Owner  shall
      instruct  its Agent  Member as provided  in (b) (i) or (ii) above,  as the
      case may be;

          (ii) each Seller's  Broker-Dealer  which is not an Agent Member of the
      Securities  Depository  shall instruct its Agent Member to (A) pay through
      the  Securities  Depository  to the Agent Member of the  Beneficial  Owner
      delivering  shares to such  Broker-Dealer  pursuant  to (b)(ii)  above the
      amount  necessary to purchase such shares against  receipt of such shares,
      and (B) deliver such shares through the Securities Depository to a Buyer's
      Broker-Dealer  (or its Agent Member)  identified to such Seller's  Broker-
      Dealer pursuant to (a)(v) above against payment therefor; and



                                      B-31
<PAGE>

            (iii) each Buyer's Broker-Dealer which is not an Agent Member of the
      Securities  Depository  shall instruct its Agent Member to (A) pay through
      the  Securities  Depository  to a  Seller's  Broker-Dealer  (or its  Agent
      Member)  identified  pursuant  to (a) (vi) above the amount  necessary  to
      purchase  the shares to be  purchased  pursuant  to (b)(i)  above  against
      receipt of such shares, and (B) deliver such shares through the Securities
      Depository to the Agent Member of the purchaser  thereof  against  payment
      therefor.

          (e) On the day after the Auction Date:  (i) each Bidder's Agent Member
      referred to in (d)

          (i) above shall  instruct  the  Securities  Depository  to execute the
      transactions  described  in (b) (i) or  (ii)  above,  and  the  Securities
      Depository shall execute such transactions;

          (ii) each Seller's  Broker-Dealer  or its Agent Member shall  instruct
      the Securities Depository to execute the transactions described in (d)(ii)
      above, and the Securities Depository shall execute such transactions; and

          (iii) each Buyer's  Broker-Dealer  or its Agent Member shall  instruct
      the  Securities  Depository to execute the  transactions  described in (d)
      (iii)  above,   and  the   Securities   Depository   shall   execute  such
      transactions.

      (f) If a Beneficial  Owner  selling  shares of APS in an Auction  fails to
deliver such shares (by authorized  book-entry),  a Broker-Dealer may deliver to
the  Potential  Beneficial  Owner on behalf of which it submitted a Bid that was
accepted a number of whole  shares of APS that is less than the number of shares
that otherwise was to be purchased by such Potential  Beneficial  Owner. In such
event, the number of shares of APS to be so delivered shall be determined solely
by such Broker-Dealer. Delivery of such lesser number of shares shall constitute
good delivery.  Notwithstanding  the foregoing  terms of this paragraph (f), any
delivery or  non-delivery of shares which shall represent any departure from the
results of an Auction, as determined by the Auction Agent, shall be of no effect
unless and until the Auction  Agent shall have been notified of such delivery or
non-delivery  in accordance  with the provisions of the Auction Agent  Agreement
and the Broker-Dealer Agreements.

      The  following  procedures  will be set forth in provisions of the Amended
By-Laws  relating  to the APS,  and will be  incorporated  by  reference  in the
Auction Agent Agreement and each Broker-Dealer  Agreement. The terms not defined
below are defined in the forepart of this Prospectus.  Nothing contained in this
Appendix C constitutes a  representation  by the Trust that in each Auction each
party referred to herein actually will perform the procedures  described  herein
to be performed by such party.

      PARAGRAPH 10(A) CERTAIN DEFINITIONS.

      As used in this Paragraph 10, the following terms shall have the following
meanings, unless the context otherwise requires:

      (i) "APS"  shall mean the shares of APS being  auctioned  pursuant to this
Paragraph 10.

      (ii) "Auction  Date" shall mean the first Business Day preceding the first

      (iii)  "Available  APS"  shall have the  meaning  specified  in  Paragraph

Applicable  Percentage of the Reference Rate. The Applicable  Percentage will be
determined  based on (i) the credit rating  assigned on such date to such shares
by S&P (or if S&P shall not make such rating  available,  the equivalent of such
rating by a Substitute  Rating Agency),  and (ii) whether the Trust has provided
modification  to the  Auction  Agent  prior  to  the  Auction  establishing  the
Applicable  Rate for any dividend that net capital gains or other taxable income
will be included in such dividend on APS as follows:

                                             Applicable
                                            Percentage of        Applicable

                             S&P                 No            Reference Rate

                          A- to A+              125%                160%
                        BBB- to BBB+            150%                250%
                         Below BBB-             200%                275%

      The Trust  shall take all  reasonable  action  necessary  to enable S&P to
provide a rating  for the APS.  If S&P  shall not make such a rating  available,
_________________________ or its affiliates and successors,  after  consultation
with  the  Trust,  shall  select  a  nationally  recognized  statistical  rating
organization to act as a Substitute Rating Agency.

      (viii)  "Order"  shall have the meaning  specified in  Paragraph  10(b)(i)
below.

       (ix) "Sell Order" shall have the meaning specified in Paragraph  10(b)(i)

      (x) "Submission Deadline" shall mean 1:00 p.m., New York City time, on any
Auction  Date or such other time on any Auction  Date as may be specified by the
Auction  Agent  from time to time as the time by which each  Broker-Dealer  must
submit to the Auction Agent in writing all Orders obtained by it for the Auction
to be conducted on such Auction Date.

      (xiii)  "Submitted  Order"  shall have the meaning  specified in Paragraph

      (xvi)  "Winning  Bid Rate" shall have the meaning  specified  in Paragraph
10(d)(i) below.

PARAGRAPH  10(B)  ORDERS BY  BENEFICIAL  OWNERS,  POTENTIAL  BENEFICIAL  OWNERS,
EXISTING HOLDERS AND POTENTIAL HOLDERS.

      (i)  Unless  otherwise  permitted  by the  Trust,  Beneficial  Owners  and
Potential  Beneficial  Owners may only  participate  in Auctions  through  their
Broker-Dealers.  Broker-Dealers  will  submit  the  Orders  of their  respective
customers  who are  Beneficial  Owners and  Potential  Beneficial  Owners to the
Auction Agent,  designating  themselves as Existing Holders in respect of shares
subject to Orders submitted or deemed submitted to them by Beneficial Owners and
as Potential Holders in respect of shares subject to Orders submitted to them by
Potential  Beneficial  Owners.  A  Broker-Dealer  may  also  hold APS in its own
account as a Beneficial  Owner.  A  Broker-Dealer  may thus submit Orders to the
Auction  Agent  as a  Beneficial  Owner  or a  Potential  Beneficial  Owner  and
therefore participate in an Auction as an Existing Holder or Potential Holder on
behalf of both itself and its customers.  On or prior to the Submission Deadline
on each Auction Date:

      (A) each Beneficial Owner may submit to its  Broker-Dealer  information as
to:

      (1) the number of outstanding  APS, if any, held by such Beneficial  Owner
which such  Beneficial  Owner desires to continue to hold without  regard to the
Applicable Rate for the next succeeding Dividend Period;

      (2) the number of outstanding  APS, if any, held by such Beneficial  Owner
which such  Beneficial  Owner  desires to  continue to hold,  provided  that the
Applicable Rate for the next  succeeding  Dividend Period shall not be less than
the rate per annum specified by such Beneficial Owner, and/or

      (3) the number of outstanding  APS, if any, held by such Beneficial  Owner
which such Beneficial Owner offers to sell without regard to the Applicable Rate
for the next succeeding Dividend Period; and



                                      B-34
<PAGE>

      (B) each Broker-Dealer,  using a list of Potential  Beneficial Owners that
shall be  maintained  in good faith for the purpose of  conducting a competitive
Auction,  shall contact Potential Beneficial Owners,  including Persons that are
not Beneficial  Owners, on such list to determine the number of outstanding APS,
if any, which each such Potential Beneficial Owner offers to purchase,  provided
that the Applicable  Rate for the next  succeeding  Dividend Period shall not be
less than the rate per annum specified by such Potential Beneficial Owner.

      For the  purposes  hereof,  the  communication  by a  Beneficial  Owner or
Potential  Beneficial  Owner  to a  Broker-Dealer,  or  the  communication  by a
Broker-Dealer  acting for its own account to the Auction  Agent,  of information
referred  to in clause  (A) or (B) of this  Paragraph  10(b)(i)  is  hereinafter
referred  to  as an  "Order"  and  each  Beneficial  Owner  and  each  Potential
Beneficial  Owner  placing an Order,  including a  Broker-Dealer  acting in such
capacity for its own account, is hereinafter referred to as a "Bidder"; an Order
containing  the  information  referred  to in clause  (A)(1)  of this  Paragraph
10(b)(i) is hereinafter  referred to as a "Hold Order";  an Order containing the
information  referred to in clause (A)(2) or (B) of this  Paragraph  10(b)(i) is
hereinafter  referred to as a "Bid";  and an Order  containing  the  information
referred to in clause (A)(3) of this Paragraph 10(b)(i) is hereinafter  referred
to as a "Sell Order." Inasmuch as a Broker-Dealer  participates in an Auction as
an Existing  Holder or a Potential  Holder only to represent  the interests of a
Beneficial Owner or Potential  Beneficial Owner,  whether it be its customers or
itself,  all discussion  herein  relating to the  consequences of an Auction for
Existing Holders and Potential Holders also applies to the underlying beneficial
ownership interests represented.

      (ii) (A) A Bid by an Existing Holder shall constitute an irrevocable offer
to sell:

      (1) the number of outstanding  APS specified in such Bid if the Applicable
Rate  determined  on such  Auction  Date  shall be less  than the rate per annum
specified in such Bid; or

      (2) such number or a lesser number of outstanding  APS to be determined as
set forth in Paragraph  10(e)(i)(D)  if the Applicable  Rate  determined on such
Auction Date shall be equal to the rate per annum specified therein; or

      (3) a lesser  number of  outstanding  APS to be determined as set forth in
Paragraph 10(e)(ii)(C) if such specified rate per annum shall be higher than the
Maximum Applicable Rate and Sufficient Clearing Bids do not exist.

      (B) A Sell Order by an Existing  Holder shall  constitute  an  irrevocable
offer to sell:

      (1) the number of outstanding APS specified in such Sell Order, or

      (2) such number or a lesser number of outstanding  APS to be determined as
set forth in Paragraph 10(e)(ii)(C) if Sufficient Clearing Bids do not exist.

      (C) A Bid by a Potential Holder shall  constitute an irrevocable  offer to
purchase:

      (1) the number of outstanding  APS specified in such Bid if the Applicable
Rate  determined  on such  Auction  Date shall be higher than the rate per annum
specified in such Bid; or

      (2) such number or a lesser number of outstanding  APS to be determined as

PARAGRAPH 10(C) SUBMISSION OF ORDERS BY BROKER-DEALERS TO AUCTION AGENT.

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

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

      (B) the aggregate  number of outstanding  APS that are the subject of such
Order;

      (C) to the extent that such Bidder is an Existing Holder

      (1) the  number of  outstanding  APS,  if any,  subject  to any Hold Order
placed by such Existing Holder;

      (2) the number of  outstanding  APS, if any,  subject to any Bid placed by
such Existing Holder and the rate per annum specified in such Bid; and

      (3) the  number of  outstanding  APS,  if any,  subject  to any Sell Order
placed by such Existing Holder; and

      (D) to the extent such Bidder is a  Potential  Holder,  the rate per annum
specified in such Potential Holder's Bid.

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

      (iii) If an Order or Orders covering all of the outstanding APS held by an
Existing  Holder are not submitted to the Auction Agent prior to the  Submission
Deadline,  the Auction  Agent shall deem a Hold Order (in the case of an Auction
relating to a Dividend Period which is not a Special Dividend Period) and a Sell
Order (in the case of an Auction  relating to a Special Dividend Period) to have
been  submitted  on  behalf  of such  Existing  Holder  covering  the  number of
outstanding APS held by such Existing Holder and not subject to Orders submitted
to the Auction Agent.

      (iv) If one or more Orders on behalf of an Existing Holder covering in the
aggregate more than the number of outstanding  APS held by such Existing  Holder
are submitted to the Auction  Agent,  such Orders shall be  considered  valid as
follows and in the following order of priority:

      (A) any Hold Order  submitted on behalf of such  Existing  Holder shall be
considered  valid up to and including the number of outstanding APS held by such
Existing  Holder;  provided  that if more than one Hold  Order is  submitted  on
behalf of such Existing Holder and the number of APS subject to such Hold Orders
exceeds the number of outstanding APS held by such Existing  Holder,  the number
of APS  subject to each of such Hold  Orders  shall be reduced  pro rata so that
such Hold Orders, in the aggregate,  cover exactly the number of outstanding APS
held by such Existing Holder;



                                      B-36
<PAGE>

      (B) any  Bids  submitted  on  behalf  of such  Existing  Holder  shall  be
considered  valid, in the ascending order of their respective rates per annum if
more than one Bid is  submitted  on behalf of such  Existing  Holder,  up to and
including  the excess of the  number of  outstanding  APS held by such  Existing
Holder over the number of shares of APS subject to any Hold Order referred to in
Paragraph  10(c)(iv)(A)  above (and if more than one Bid  submitted on behalf of
such Existing  Holder  specifies the same rate per annum and together they cover
more than the  remaining  number of shares that can be the subject of valid Bids
after application of Paragraph  10(c)(iv)(A)  above and of the foregoing portion
of this  Paragraph  10(c)(iv)(B)  to any Bid or Bids  specifying a lower rate or
rates per  annum,  the  number of shares  subject  to each of such Bids shall be
reduced  pro rata so that  such  Bids,  in the  aggregate,  cover  exactly  such
remaining number of shares);  and the number of shares,  if any, subject to Bids
not valid under this Paragraph 10(c)(iv)(B) shall be treated as the subject of a
Bid by a Potential Holder; and

      (C) any Sell  Order  shall be  considered  valid up to and  including  the
excess of the number of  outstanding  APS held by such Existing  Holder over the
number of APS subject to Hold Orders referred to in Paragraph  10(c)(iv)(A)  and
Bids referred to in Paragraph 10(c)(iv)(B);  provided that if more than one Sell
Order is  submitted  on  behalf of any  Existing  Holder  and the  number of APS
subject  to such Sell  Orders is  greater  than such  excess,  the number of APS
subject to each of such Sell Orders  shall be reduced pro rata so that such Sell
Orders, in the aggregate, cover exactly the number of APS equal to such excess.

      (v) If more than one Bid is submitted on behalf of any  Potential  Holder,
each Bid submitted shall be a separate Bid with the rate per annum and number of
APS therein specified.

      (vi) Any Order submitted by a Beneficial  Owner or a Potential  Beneficial
Owner to its Broker-Dealer, or by a Broker-Dealer to the Auction Agent, prior to
the Submission Deadline on any Auction Date shall be irrevocable.

PARAGRAPH 10(D)  DETERMINATION OF SUFFICIENT CLEARING BIDS, WINNING BID RATE AND
APPLICABLE RATE.

      (i) Not earlier than the  Submission  Deadline on each Auction  Date,  the
Auction Agent shall assemble all Orders  submitted or deemed  submitted to it by
the  Broker-Dealers  (each  such Order as  submitted  or deemed  submitted  by a
Broker-Dealer  being  hereinafter  referred to individually as a "Submitted Hold
Order," a "Submitted Bid" or a "Submitted Sell Order," as the case may be, or as
a "Submitted Order") and shall determine:

      (A) the excess of the total number of  outstanding  APS over the number of
outstanding APS that are the subject of Submitted Hold Orders (such excess being
hereinafter referred to as the "Available APS");

      (B) from the Submitted  Orders whether the number of outstanding  APS that
are the subject of Submitted  Bids by Potential  Holders  specifying one or more
rates per annum equal to or lower than the Maximum Applicable Rate exceeds or is
equal to the sum of:

      (1) the number of  outstanding  APS that are the subject of Submitted Bids
by  Existing  Holders  specifying  one or more rates per annum  higher  than the
Maximum Applicable Rate, and

      (2) the  number of  outstanding  APS that are  subject to  Submitted  Sell
Orders (if such excess or such equality exists (other than because the number of
outstanding  APS in clauses  (1) and (2) above are each zero  because all of the


                                      B-37
<PAGE>

outstanding  APS are the subject of Submitted Hold Orders),  such Submitted Bids
by Potential  Holders  hereinafter being referred to collectively as "Sufficient
Clearing Bids"); and

      (C) if Sufficient Clearing Bids exist, the lowest rate per annum specified
in the Submitted Bids (the "Winning Bid Rate") that if:

      (1) each  Submitted Bid from Existing  Holders  specifying the Winning Bid
Rate and all other submitted Bids from Existing  Holders  specifying lower rates
per annum were rejected,  thus  entitling  such Existing  Holders to continue to
hold the shares of APS that are the subject of such Submitted Bids, and

      (2) each Submitted Bid from Potential  Holders  specifying the Winning Bid
Rate and all other Submitted Bids from Potential Holders  specifying lower rates
per annum were accepted,  thus  entitling the Potential  Holders to purchase the
APS that are the subject of such Submitted  Bids,  would result in the number of
shares subject to all Submitted Bids  specifying the Winning Bid Rate or a lower
rate per annum being at least equal to the Available APS.

      (ii) Promptly after the Auction Agent has made the determinations pursuant
to Paragraph  10(d)(i),  the Auction Agent shall advise the Trust of the Maximum
Applicable Rate and, based on such  determinations,  the Applicable Rate for the
next succeeding Dividend Period as follows:

      (A) if Sufficient  Clearing Bids exist,  that the Applicable  Rate for the
next succeeding Dividend Period shall be equal to the Winning Bid Rate;

      (B) if  Sufficient  Clearing  Bids do not exist (other than because all of
the  outstanding  APS are the  subject  of  Submitted  Hold  Orders),  that  the
Applicable  Rate for the next  succeeding  Dividend Period shall be equal to the
Maximum Applicable Rate; or

      (C) if all of the  outstanding  APS  are the  subject  of  Submitted  Hold
Orders, that the Dividend Period next succeeding the Auction automatically shall
be the  same  length  as the  immediately  preceding  Dividend  Period  and  the
Applicable Rate for the next succeeding Dividend Period shall be equal to 59% of
the Reference  Rate (or 90% of such rate if the Trust has provided  notification
to the Auction Agent prior to the Auction  establishing  the Applicable Rate for
any dividend that net capital gains or other taxable  income will be included in
such dividend on APS) on the date of the Auction.

PARAGRAPH  10(E)  ACCEPTANCE  AND REJECTION OF SUBMITTED BIDS AND SUBMITTED SELL
ORDERS AND ALLOCATION OF SHARES.

      Based on the  determinations  made  pursuant to  Paragraph  10(d)(i),  the
Submitted  Bids and Submitted  Sell Orders shall be accepted or rejected and the
Auction Agent shall take such other action as set forth below:

      (i) If Sufficient  Clearing Bids have been made, subject to the provisions
of Paragraph  10(e)(iii) and Paragraph  10(e)(iv),  Submitted Bids and Submitted
Sell Orders shall be accepted or rejected in the following order of priority and
all other Submitted
Bids shall be rejected:

      (A) the  Submitted  Sell Orders of Existing  Holders shall be accepted and
the Submitted Bid of each of the Existing Holders  specifying any rate per annum
that is higher than the Winning Bid Rate shall be accepted,  thus requiring each
such Existing Holder to sell the outstanding  shares of APS that are the subject
of such Submitted Sell Order or Submitted Bid;



                                      B-38
<PAGE>

      (B) the Submitted Bid of each of the Existing  Holder  specifying any rate
per annum  that is lower  than the  Winning  Bid Rate  shall be  rejected,  thus
entitling each such Existing Holder to continue to hold the outstanding APS that
are the subject of such Submitted Bid;

      (C) the Submitted Bid of each of the Potential Holders specifying any rate
per annum that is lower than the Winning Bid Rate shall be accepted;

      (D) the  Submitted Bid of each of the Existing  Holders  specifying a rate
per  annum  that is  equal to the  Winning  Bid Rate  shall  be  rejected,  thus
entitling each such Existing Holder to continue to hold the outstanding APS that
are the subject of such Submitted Bid,  unless the number of outstanding  shares
of APS subject to all such  Submitted  Bids shall be greater  than the number of
outstanding  APS  ("Remaining  Shares") equal to the excess of the Available APS
over the number of  outstanding  APS  subject to  Submitted  Bids  described  in
Paragraph  10(e)(i)(B) and Paragraph  10(e)(i)(C),  in which event the Submitted
Bids of each such  Existing  Holder  shall be accepted,  and each such  Existing
Holder  shall be  required  to sell  outstanding  shares of APS,  but only in an
amount equal to the difference  between (1) the number of  outstanding  APS then
held by such Existing Holder subject to such Submitted Bid and (2) the number of
APS obtained by multiplying (x) the number of Remaining Shares by (y) a fraction
the  numerator  of which  shall be the  number of  outstanding  APS held by such
Existing Holder subject to such Submitted Bid and the denominator of which shall
be the sum of the numbers of outstanding APS subject to such Submitted Bids made
by all such  Existing  Holders  that  specified  a rate per  annum  equal to the
Winning Bid Rate; and

      (E) the Submitted Bid of each of the Potential  Holders  specifying a rate
per annum that is equal to the Winning Bid Rate shall be accepted but only in an
amount equal to the number of outstanding  APS obtained by  multiplying  (x) the
difference  between the Available APS and the number of outstanding  APS subject
to Submitted Bids described in Paragraph 10(e)(i)(B),  Paragraph 10(e)(i)(C) and
Paragraph  10(e)(i)(D)  by (y) a fraction  the  numerator  of which shall be the
number of outstanding  APS subject to such Submitted Bid and the  denominator of
which  shall  be the  sum of the  number  of  outstanding  APS  subject  to such
Submitted Bids made by all such Potential Holders that specified rates per annum
equal to the Winning Bid Rate.

      (ii) If  Sufficient  Clearing  Bids have not been made (other than because
all of the outstanding APS are subject to Submitted Hold Orders), subject to the
provisions  of  Paragraph  10(e)(iii),  Submitted  Orders  shall be  accepted or
rejected as follows in the following  order of priority and all other  Submitted
Bids shall be rejected:

      (A) the  Submitted  Bid of each Existing  Holder  specifying  any rate per
annum  that is equal  to or lower  than the  Maximum  Applicable  Rate  shall be
rejected,   thus  entitling  such  Existing  Holder  to  continue  to  hold  the
outstanding APS that are the subject of such Submitted Bid;

      (B) the Submitted Bid of each  Potential  Holder  specifying  any rate per
annum  that is equal  to or lower  than the  Maximum  Applicable  Rate  shall be
accepted,  thus requiring such Potential  Holder to purchase the outstanding APS
that are the subject of such Submitted Bid; and

      (C) the Submitted  Bids of each Existing  Holder  specifying  any rate per
annum that is higher than the Maximum  Applicable Rate shall be accepted and the
Submitted Sell Orders of each Existing  Holder shall be accepted,  in both cases
only in an amount equal to the difference  between (1) the number of outstanding
APS then held by such Existing Holder subject to such Submitted Bid or Submitted
Sell Order and (2) the number of APS obtained by multiplying  (x) the difference
between the Available APS and the aggregate number of outstanding APS subject to
Submitted Bids described in Paragraph 10(e)(ii)(A) and Paragraph 10(e)(ii)(B) by


                                      B-39
<PAGE>

(y) a fraction  the  numerator of which shall be the number of  outstanding  APS
held by such Existing  Holder  subject to such  Submitted Bid or Submitted  Sell
Order  and the  denominator  of which  shall be the  number of  outstanding  APS
subject to all such Submitted Bids and Submitted Sell Orders.

      (iii) If, as a result of the procedures described in Paragraph 10(e)(i) or
Paragraph 10(e)(ii),  any Existing Holder would be entitled or required to sell,
or any Potential Holder would be entitled or required to purchase, a fraction of
a APS on any Auction  Date,  the Auction  Agent shall,  in such manner as in its
sole  discretion  it shall  determine,  round up or down the number of APS to be
purchased  or sold by any Existing  Holder or  Potential  Holder on such Auction
Date so that each  outstanding  APS purchased or sold by each Existing Holder or
Potential Holder on such Auction Date shall be a whole APS.

      (iv) If, as a result of the  procedures  described in Paragraph  10(e)(i),
any Potential Holder would be entitled or required to purchase less than a whole
share of APS on any Auction Date,  the Auction  Agent,  in such manner as in its
sole  discretion  it shall  determine,  shall  allocate APS for  purchase  among
Potential Holders so that only whole shares of APS are purchased on such Auction
Date by any Potential Holder,  even if such allocation results in one or more of
such Potential Holders not purchasing any APS on such Auction Date.

      (v)  Based  on the  results  of each  Auction,  the  Auction  Agent  shall
determine, with respect to each Broker-Dealer that submitted Bids or Sell Orders
on behalf of Existing Holders or Potential Holders,  the aggregate number of the
outstanding  APS to be purchased and the aggregate  number of outstanding APS to
be sold by such Potential  Holders and Existing  Holders and, to the extent that
such aggregate  number of outstanding  shares to be purchased and such aggregate
number  of  outstanding  shares  to be sold  differ,  the  Auction  Agent  shall
determine to which other Broker-Dealer or Broker-Dealers  acting for one or more
purchasers such Broker-Dealer  shall deliver,  or from which other Broker-Dealer
or  Broker-Dealers  acting  for one or more  sellers  such  Broker-Dealer  shall
receive, as the case may be, outstanding APS.

PARAGRAPH 10(F) MISCELLANEOUS.

      The Trust may interpret the provisions of this Paragraph 10 to resolve any
inconsistency or ambiguity, remedy any formal defect or make any other change or
modification  that  does  not  substantially  adversely  affect  the  rights  of
Beneficial Owners of APS. A Beneficial Owner or an Existing Holder (A) may sell,
transfer  or  otherwise  dispose of APS only  pursuant to a Bid or Sell Order in
accordance with the procedures described in this Paragraph 10 or to or through a
Broker-Dealer, provided that in the case of all transfers other than pursuant to
Auctions  such  Beneficial  Owner or  Existing  Holder,  its  Broker-Dealer,  if
applicable,  or its Agent Member  advises the Auction Agent of such transfer and
(B) except as  otherwise  required by law,  shall have the  ownership of the APS
held by it  maintained  in book entry form by the  Securities  Depository in the
account  of its  Agent  Member,  which in turn  will  maintain  records  of such
Beneficial  Owner's  beneficial  ownership.  Neither the Trust nor any Affiliate
(other than _________________________) shall submit an Order in any Auction. Any
Beneficial  Owner that is an  Affiliate  (other than  _________________________)
shall not sell,  transfer or  otherwise  dispose of APS to any Person other than
the Trust.  All of the  outstanding  APS of a Series shall be  represented  by a
single  certificate  registered  in the name of the  nominee  of the  Securities
Depository  unless  otherwise  required by law or unless there is no  Securities
Depository. If there is no Securities Depository, at the Trust's option and upon
its receipt of such documents as it deems appropriate, any APS may be registered
in the Stock  Register  in the name of the  Beneficial  Owner  thereof  and such


                                      B-40
<PAGE>

Beneficial Owner thereupon will be entitled to receive certificates therefor and
required to deliver certificates thereof or upon transfer or exchange thereof.

ITEM 29.  INDEMNIFICATION

    The  Registrant's  By-Laws and Form of Amendment  No. 1 filed herein and the
Underwriting  Agreement to be filed contain  provisions  limiting the liability,
and providing for  indemnification,  of the Trustees and officers  under certain
circumstances.

    Registrant's  Trustees and officers are insured under a standard  investment
company errors and omissions  insurance  policy covering loss incurred by reason
of negligent errors and omissions committed in their capacities as such.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to trustees,  officers and  controlling  persons of the
Registrant and the Adviser and any  underwriter  to the foregoing  provisions or
otherwise, the Registrant has been advised that in the opinion of the Securities
and  Exchange  Commission  such  indemnification  is  against  public  policy as
expressed  in such Act and is,  therefore,  unenforceable.  In the event  that a
claim for  indemnification  against such liabilities  (other than the payment by
the  Registrant  of  expenses  incurred  or  paid  by  a  trustee,  officer,  or
controlling person or the Registrant and the Underwriters in connection with the
successful  defense of any action,  suit or proceeding) is asserted  against the
Registrant by such trustee,  officer or controlling person or the Distributor in
connection with the Common Shares being registered,  the Registrant will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such indemnification by it is against public policy as expressed in such Act and
will be governed by the final adjudication of such issue.

ITEM 30.  BUSINESS AND OTHER CONNECTIONS OF THE INVESTMENT ADVISER

    Reference  is made to:  (i) the  information  set forth  under  the  caption
"Investment  Advisory  and  Other  Services"  in  the  Statement  of  Additional

Act of 1934 (File No. 1-8100);  and (iii) the Form ADV of Eaton Vance Management

herein by reference.

the  Registrant by Section 31(a) of the  Investment  Company Act of 1940 and the

                                   DESIGNATION

      Auction  Preferred  Shares:  An unlimited  number of shares of  beneficial
interest of Preferred Shares, par value $.01 per share,  liquidation  preference

authority; have an Initial Dividend Rate and an Initial Dividend Payment Date as

of the Trust or  pursuant  to their  delegated  authority;  and have such  other
preferences,  voting  powers,  limitations as to dividends,  qualifications  and
terms and  conditions of  redemption as are set forth in these Amended  By-Laws.
The Auction  Preferred  Shares shall  constitute a separate  series of Preferred
Shares  of the  Trust,  and each  share of  Auction  Preferred  Shares  shall be

      1.  DEFINITIONS.  (a) Unless the context or use indicates another or
different meaning or intent, in these Amended By-Laws the following terms
have the following meanings, whether used in the singular or plural:

means (i) the  Interest  Equivalent  of the rate on  commercial  paper placed on
behalf of issuers whose corporate bonds are rated "AA" by S&P or "Aa" by Moody's

Reserve Bank of New York for the Business Day  immediately  preceding such date,
or (ii) in the event  that the  Federal  Reserve  Bank of New York does not make
available such a rate, then the arithmetic average of the Interest Equivalent of

Agent for the close of business on the Business Day  immediately  preceding such
date. If one of the  Commercial  Paper Dealers does not quote a rate required to
determine  the  "AA"  Composite   Commercial  Paper  Rate,  the  "AA"  Composite
Commercial  Paper  Rate  will be  determined  on the basis of the  quotation  or

Commercial Paper Dealers selected by the Trust to provide such rate or rates not
being supplied by the Commercial Paper Dealer.  If the number of Dividend Period
days  shall be (i) 7 or more but  fewer  than 49 days,  such  rate  shall be the
Interest Equivalent of the 30-day rate on such commercial paper; (ii) 49 or more
but fewer than 70 days, such rate shall be the Interest Equivalent of the 60-day
rate on such  commercial  paper;  (iii) 70 or more days but fewer  than 85 days,
such rate shall be the  arithmetic  average of the  Interest  Equivalent  on the
60-day and 90-day rates on such commercial paper; (iv) 85 or more days but fewer
than 99 days,  such rate shall be the Interest  Equivalent of the 90-day rate on
such  commercial  paper;  (v) 99 or more days but fewer than 120 days, such rate
shall be the  arithmetic  average of the Interest  Equivalent  of the 90-day and
120-day rates on such commercial paper; (vi) 120 or more days but fewer than 141
days,  such rate shall be the  Interest  Equivalent  of the 120-day rate on such
commercial  paper;  (vii) 141 or more days but  fewer  than 162 days,  such rate
shall be the  arithmetic  average of the Interest  Equivalent of the 120-day and
180-day rates on such  commercial  paper;  and (viii) 162 or more days but fewer
than 183 days, such rate shall be the Interest Equivalent of the 180-day rate on
such commercial paper.

      "Variation  Margin"  means,  in  connection  with an  outstanding  futures
contract owned or sold by the Trust, the amount of cash or securities paid to or
received from a broker  (subsequent to the Initial Margin  payment) from time to
time as the price of such futures contract fluctuates.

      (b) The foregoing  definitions  of  Accountant's  Confirmation,  APS Basic
Maintenance  Amount,  APS Basic  Maintenance  Cure Date,  APS Basic  Maintenance
Report, Deposit Securities,  Discounted Value,  Independent Accountant,  Initial
Margin,  Market Value,  Maximum Potential  Additional  Dividend  Liability,  S&P
Discount  Factor,   S&P  Eligible  Asset,  S&P  Exposure  Period,   S&P  Hedging
Transactions,  S&P Volatility  Factor,  Valuation Date and Variation Margin have
been  determined  by the Board of Trustees of the Trust in order to obtain a AAA
rating  from S&P on the APS on their Date of  Original  Issue;  and the Board of
Trustees of the Trust shall have the authority, without shareholder approval, to
amend,  alter or repeal  from  time to time the  foregoing  definitions  and the
restrictions and guidelines set forth thereunder if S&P or any Substitute Rating
Agency  advises the Trust in writing that such  amendment,  alteration or repeal
will not adversely affect its then current rating on the APS.

      2. DIVIDENDS.  (a) The Holders shall be entitled to receive,  when, as and
if  declared  by the  Board of  Trustees  of the  Trust,  out of  funds  legally
available  therefor,  cumulative  dividends  each  consisting of (i) cash at the
Applicable  Rate,  (ii) a Right to receive cash as set forth in  paragraph  2(e)
below,  and (iii) any  additional  amounts as set forth in paragraph 2(f) below,
and no more,  payable on the respective dates set forth below.  Dividends on the
shares of APS so declared and payable  shall be paid (i) in preference to and in
priority over any dividends  declared and payable on the Common Shares, and (ii)
to the extent permitted under the Code and to the extent  available,  out of net
tax-exempt  income earned on the Trust's  investments.  To the extent  permitted
under the Code, dividends on shares of APS will be designated as exempt-interest
dividends.  For the purposes of this section,  the term "net tax-exempt  income"
shall exclude capital gains of the Trust.

      (b) (i) Cash dividends on shares of APS shall  accumulate from the Date of
Original  Issue and shall be payable,  when,  as and if declared by the Board of
Trustees,  out of funds legally  available  therefor,  commencing on the Initial
Dividend Payment Date.  Following the Initial Dividend Payment Date for the APS,
dividends  on the APS will be  payable,  at the option of the Trust,  either (i)
with respect to any 7-Day Dividend  Period and any Short Term Dividend Period of


                                       11
<PAGE>

35 or fewer days, on the day next succeeding the last day thereof,  or (ii) with
respect to any Short Term Dividend  Period of more than 35 days and with respect
to any Long Term  Dividend  Period,  monthly on the first  Business  Day of each
calendar  month  during such Short Term  Dividend  Period or Long Term  Dividend
Period  and on the day next  succeeding  the last day  thereof  (each  such date
referred to in clause (i) or (ii) being herein referred to as a "Normal Dividend
Payment  Date"),  except  that if such  Normal  Dividend  Payment  Date is not a
Business  Day,  then the Dividend  Payment Date shall be the first  Business Day
next  succeeding  such Normal  Dividend  Payment Date.  Although any  particular
Dividend Payment Date may not occur on the originally  scheduled date because of
the  exception  discussed  above,  the next  succeeding  Dividend  Payment Date,
subject to such exception, will occur on the next following originally scheduled
date.  If for any reason a Dividend  Payment  Date cannot be fixed as  described
above, then the Board of Trustees shall fix the Dividend Payment Date. The Board
of Trustees by resolution  prior to  authorization of a dividend by the Board of
Trustees may change a Dividend  Payment  Date if such change does not  adversely
affect  the  contract  rights of the  Holders  of shares of APS set forth in the
Declaration of Trust. The Initial  Dividend  Period,  7-Day Dividend Periods and
Special  Dividend  Periods  are  hereinafter  sometimes  referred to as Dividend
Periods.  Each dividend payment date determined as provided above is hereinafter
referred to as a "Dividend Payment Date."

      (ii) Each  dividend  shall be paid to the  Holders  as they  appear in the
Stock  Register  as of 12:00  noon,  New York City  time,  on the  Business  Day
preceding the Dividend Payment Date.  Dividends in arrears for any past Dividend
Period may be declared  and paid at any time,  without  reference to any regular
Dividend  Payment Date, to the Holders as they appear on the Stock Register on a
date, not exceeding 15 days prior to the payment date therefor,  as may be fixed
by the Board of  Trustees  of the Trust.  (c) (i)  During  the  period  from and
including  the Date of Original  Issue to but  excluding  the  Initial  Dividend
Payment  Date for  each  series  of APS (the  "Initial  Dividend  Period"),  the
Applicable  Rate shall be the Initial  Dividend Rate.  Commencing on the Initial
Dividend  Payment  Date for each  series of APS,  the  Applicable  Rate for each
subsequent  dividend period (hereinafter  referred to as a "Subsequent  Dividend
Period"),  which  Subsequent  Dividend  Period  shall  commence on and include a
Dividend Payment Date and shall end on and include the calendar day prior to the
next Dividend  Payment Date (or last Dividend  Payment Date in a Dividend Period
if there is more than one Dividend Payment Date), shall be equal to the rate per
annum that results from implementation of the Auction Procedures.

      The  Applicable  Rate  for  each  Dividend  Period   commencing  during  a
Non-Payment  Period  shall be equal to the  Non-Payment  Period  Rate;  and each
Dividend  Period,  commencing  after the first day of, and during, a Non-Payment
Period  shall be a 7-Day  Dividend  Period  in the case of each  series  of APS.
Except in the case of the  willful  failure of the Trust to pay a dividend  on a
Dividend  Payment  Date or to redeem  any shares of APS on the date set for such
redemption,  any amount of any dividend  due on any  Dividend  Payment Date (if,
prior to the  close of  business  on the  second  Business  Day  preceding  such
Dividend  Payment Date,  the Trust has declared  such  dividend  payable on such
Dividend Payment Date to the Holders of such shares of APS as of 12:00 noon, New
York City time,  on the Business Day preceding  such  Dividend  Payment Date) or
redemption price with respect to any shares of APS not paid to such Holders when
due may be paid to such  Holders  in the same form of funds by 12:00  noon,  New
York City time,  on any of the first  three  Business  Days after such  Dividend
Payment  Date or due date,  as the case may be,  provided  that,  such amount is
accompanied  by a late charge  calculated  for such period of non-payment at the
Non-Payment  Period Rate applied to the amount of such non-payment  based on the
actual number of days  comprising  such period  divided by 365. In the case of a
willful failure of the Trust to pay a dividend on a Dividend  Payment Date or to
redeem  any  shares of APS on the date set for such  redemption,  the  preceding
sentence  shall  not  apply  and the  Applicable  Rate for the  Dividend  Period
commencing  during the Non-Payment  Period  resulting from such failure shall be
the  Non-Payment  Period Rate. For the purposes of the  foregoing,  payment to a
person in same-day  funds on any  Business  Day at any time shall be  considered
equivalent to payment to such person in New York Clearing House (next-day) funds
at the same time on the preceding Business Day, and any payment made after 12:00
noon,  New York City time,  on any Business Day shall be considered to have been
made instead in the same form of funds and to the same person before 12:00 noon,
New York City time, on the next Business Day. (ii) The amount of cash  dividends
per share of any series of APS payable  (if  declared)  on the Initial  Dividend
Payment Date, each 7-Day Dividend Period and each Dividend  Payment Date of each
Short Term Dividend  Period shall be computed by multiplying the Applicable Rate
for such  Dividend  Period by a  fraction,  the  numerator  of which will be the
number of days in such  Dividend  Period  or part  thereof  that such  share was
outstanding and the denominator of which will be 365,  multiplying the amount so
obtained by $25,000,  and rounding  the amount so obtained to the nearest  cent.
During any Long Term Dividend Period,  the amount of cash dividends per share of


                                       12
<PAGE>

APS payable (if  declared)  on any  Dividend  Payment  Date shall be computed by
multiplying  the  Applicable  Rate for such Dividend  Period by a fraction,  the
numerator  of which  will be such  number of days in such part of such  Dividend
Period that such share was  outstanding  and for which  dividends are payable on
such Dividend Payment Date and the denominator of which will be 360, multiplying
the amount so obtained by $25,000,  and  rounding  the amount so obtained to the
nearest cent.

      (iii) With  respect to each  Dividend  Period  that is a Special  Dividend
Period, the Trust may, at its sole option and to the extent permitted by law, by
telephonic and written notice (a "Request for Special  Dividend  Period") to the
Auction  Agent  and to each  Broker-Dealer,  request  that the  next  succeeding
Dividend  Period  for a series of APS be a number of days  (other  than  seven),
evenly divisible by seven and not fewer than seven nor more than 364 in the case
of a Short Term  Dividend  Period or one whole year or more but not greater than
five years in the case of a Long Term Dividend Period, specified in such notice,
provided  that the Trust may not give a Request for Special  Dividend  Period of
greater than 28 days (and any such request shall be null and void)  unless,  for
any Auction occurring after the initial Auction,  Sufficient  Clearing Bids were
made in the last occurring  Auction and unless full  cumulative  dividends,  any
amounts due with respect to redemption's,  and any Additional  Dividends payable
prior to such date have been paid in full.  Such  Request for  Special  Dividend
Period, in the case of a Short Term Dividend Period,  shall be given on or prior
to the second  Business  Day but not more than seven  Business  Days prior to an
Auction  Date for a  series  of APS and,  in the  case of a Long  Term  Dividend
Period,  shall be given on or prior to the second Business Day but not more than
28 days prior to an Auction Date for the APS.  Upon  receiving  such Request for
Special Dividend Period, the  Broker-Dealer(s)  shall jointly determine whether,
given the factors set forth below, it is advisable that the Trust issue a Notice
of Special Dividend Period for the series of APS as contemplated by such Request
for Special Dividend Period and the Optional  Redemption Price of the APS during
such Special  Dividend Period and the Specific  Redemption  Provisions and shall
give the Trust and the  Auction  Agent  written  notice (a  "Response")  of such
determination  by no later than the second  Business  Day prior to such  Auction
Date.  In making such  determination  the  Broker-Dealer(s)  will  consider  (1)
existing  short-term and long-term  market rates and indices of such  short-term
and long-term  rates,  (2) existing  market supply and demand for short-term and
long-term  securities,  (3) existing  yield curves for  short-term and long-term
securities  comparable to the APS, (4) industry and financial  conditions  which
may affect  the APS,  (5) the  investment  objective  of the Trust,  and (6) the
Dividend  Periods and dividend  rates at which current and potential  beneficial
holders  of  the  APS  would  remain  or  become  beneficial   holders.  If  the
Broker-Dealer(s)  shall not give the Trust and the  Auction  Agent a Response by
such second  Business Day or if the  Response  states that given the factors set
forth above it is not advisable that the Trust give a Notice of Special Dividend
Period  for the  series  of APS,  the  Trust  may not give a Notice  of  Special
Dividend Period in respect of such Request for Special Dividend  Period.  In the
event the Response  indicates  that it is advisable that the Trust give a Notice
of Special Dividend Period for the series of APS, the Trust may by no later than
the second  Business  Day prior to such Auction Date give a notice (a "Notice of
Special Dividend  Period") to the Auction Agent,  the Securities  Depository and
each  Broker-Dealer  which  notice will  specify (i) the duration of the Special
Dividend Period,  (ii) the Optional Redemption Price as specified in the related
Response and (iii) the Specific Redemption  Provisions,  if any, as specified in
the  related  Response.  The Trust also shall  provide a copy of such  Notice of
Special Dividend Period to Moody's and S&P. The Trust shall not give a Notice of
Special Dividend Period and, if the Trust has given a Notice of Special Dividend
Period,  the Trust is required  to give  telephonic  and  written  notice of its
revocation (a "Notice of Revocation") to the Auction Agent, each  Broker-Dealer,
and the  Securities  Depository  on or prior to the  Business  Day  prior to the
relevant  Auction  Date if (x)  either  the 1940 Act APS Asset  Coverage  is not
satisfied  or the Trust  shall fail to  maintain  S&P  Eligible  Assets  with an
aggregate  Discounted Value at least equal to the APS Basic Maintenance  Amount,
on each of the two Valuation Dates immediately  preceding the Business Day prior
to the relevant  Auction Date on an actual basis and on a pro forma basis giving
effect to the proposed  Special  Dividend  Period (using as a pro forma dividend
rate with respect to such Special  Dividend  Period the dividend  rate which the
Broker-Dealers  shall  advise  the  Trust  is an  approximately  equal  rate for
securities  similar to the APS with an equal  dividend  period),  (y) sufficient
funds  for the  payment  of  dividends  payable  on the  immediately  succeeding
Dividend Payment Date have not been irrevocably deposited with the Auction Agent
by the close of business on the third Business Day preceding the related Auction
Date  or  (z)  the   Broker-Dealer(s)   jointly  advise  the  Trust  that  after
consideration  of the  factors  listed  above  they  have  concluded  that it is
advisable to give a Notice of Revocation. The Trust also shall provide a copy of
such  Notice of  Revocation  to S&P.  If the Trust is  prohibited  from giving a
Notice of Special  Dividend Period as a result of any of the factors  enumerated
in clause  (x),  (y) or (z) above or if the Trust  gives a Notice of  Revocation
with respect to a Notice of Special  Dividend  Period for any series of APS, the
next succeeding Dividend Period will be a 7-Day Dividend Period. In 35 addition,


                                       13
<PAGE>

in the event Sufficient  Clearing Bids are not made in the applicable Auction or
such Auction is not held for any reason,  such next  succeeding  Dividend Period
will be a 7-Day  Dividend  Period  and the Trust may not again  give a Notice of
Special Dividend Period for the APS (and any such attempted notice shall be null
and void)  until  Sufficient  Clearing  Bids have been made in an  Auction  with
respect to a 7-Day Dividend Period.

      (d) (i) Holders shall not be entitled to any dividends, whether payable in
cash,  property or stock, in excess of full cumulative  dividends and applicable
late charges,  as herein  provided,  on the shares of APS (except for Additional
Dividends  as  provided in  paragraph  2(e)  hereof and  additional  payments as
provided in paragraph 2(f) hereof).  Except for the late charge payable pursuant
to paragraph 2(c)(i) hereof,  no interest,  or sum of money in lieu of interest,
shall be payable in  respect of any  dividend  payment on the shares of APS that
may be in arrears.

      (ii) For so long as any share of APS is  Outstanding,  the Trust shall not
declare,  pay or set apart for payment any dividend or other distribution (other
than a dividend  or  distribution  paid in shares of, or  options,  warrants  or
rights to subscribe for or purchase, Common Shares or other shares of beneficial
interest,  if any,  ranking  junior to the shares of APS as to dividends or upon
liquidation)  in respect of the Common  Shares or any other shares of beneficial
interest of the Trust ranking junior to or on a parity with the shares of APS as
to dividends or upon liquidation,  or call for redemption,  redeem,  purchase or
otherwise acquire for consideration any shares of the Common Shares or any other
such junior  shares  (except by  conversion  into or exchange  for shares of the
Trust ranking junior to the shares of APS as to dividends and upon  liquidation)
or any other such Parity Shares (except by conversion into or exchange for stock
of the  Trust  ranking  junior  to or on a parity  with the  shares of APS as to
dividends and upon liquidation),  unless (A) immediately after such transaction,
the Trust shall have S&P  Eligible  Assets with an  aggregate  Discounted  Value
equal to or greater  than the APS Basic  Maintenance  Amount and the Trust shall
maintain  the 1940 Act APS Asset  Coverage,  (B) full  cumulative  dividends  on
shares  of APS and  shares  of  Other  APS due on or  prior  to the  date of the
transaction  have  been  declared  and  paid or shall  have  been  declared  and
sufficient  funds for the payment thereof  deposited with the Auction Agent, (C)
any  Additional  Dividend  required to be paid under  paragraph 2(e) below on or
before the date of such  declaration  or payment has been paid and (D) the Trust
has  redeemed  the full  number of shares of APS  required to be redeemed by any
provision for mandatory redemption contained herein.

      (e) Each dividend shall consist of (i) cash at the Applicable  Rate,  (ii)
an  uncertificated  right (a  "Right")  to receive an  Additional  Dividend  (as
defined below),  and (iii) any additional amounts as set forth in paragraph 2(f)
below.  Each Right shall thereafter be independent of the share or shares of APS
on which the dividend was paid.  The Trust shall cause to be maintained a record
of each Right received by the respective Holders. A Right may not be transferred
other than by operation  of law. If the Trust  retroactively  allocates  any net
capital gains or other income subject to regular  Federal income taxes to shares
of APS without  having  given  advance  notice  thereof to the Auction  Agent as
described  in  paragraph  2(f)  hereof  solely  by  reason of the fact that such
allocation  is made as a result of the  redemption  of all or a  portion  of the
outstanding  shares of APS or the  liquidation  of the Trust (the amount of such
allocation referred to herein as a "Retroactive Taxable Allocation"),  the Trust
will, within 90 days (and generally within 60 days) after the end of the Trust's
fiscal year for which a Retroactive  Taxable  Allocation is made, provide notice
thereof to the Auction  Agent and to each holder of a Right  applicable  to such
shares of APS (initially as nominee of The Depository Trust Company) during such
fiscal year at such holder's address as the same appears or last appeared on the
Stock Books of the Trust.  The Trust  will,  within 30 days after such notice is
given to the Auction Agent,  pay to the Auction Agent (who will then  distribute
to such holders of Rights),  out of funds legally available therefor,  an amount
equal to the  aggregate  Additional  Dividend  with  respect to all  Retroactive
Taxable Allocations made to such holders during the fiscal year in question.

      An  "Additional  Dividend"  means payment to a present or former holder of
shares of APS of an amount which,  when taken together with the aggregate amount
of  Retroactive  Taxable  Allocations  made to such holder  with  respect to the
fiscal year in question,  would cause such holder's  dividends in dollars (after
Federal  income tax  consequences)  from the  aggregate of both the  Retroactive
Taxable Allocations and the Additional Dividend to be equal to the dollar amount
of the dividends  which would have been received by such holder if the amount of
the aggregate  Retroactive  Taxable  Allocations would have been excludable from
the gross income of such holder.  Such  Additional  Dividend shall be calculated
(i) without  consideration being given to the time value of money; (ii) assuming
that no holder of shares of APS is subject to the  Federal  alternative  minimum
tax with respect to dividends  received from the Trust;  and (iii) assuming that


                                       14
<PAGE>

each Retroactive Taxable Allocation would be taxable in the hands of each holder
of shares of APS at the  greater of: (x) the maximum  marginal  regular  Federal
individual  income tax rate  applicable  to  ordinary  income or  capital  gains
depending on the taxable  character of the distribution  (including any surtax);
or (y) the maximum marginal regular Federal corporate income tax rate applicable
to ordinary  income or capital gains  depending on the taxable  character of the
distribution  (disregarding in both (x) and (y) the effect of any state or local
taxes and the phase out of, or provision limiting, personal exemptions, itemized
deductions, or the benefit of lower tax brackets).

      (f) Except as provided  below,  whenever the Trust  intends to include any
net capital gains or other income subject to regular Federal income taxes in any
dividend on shares of APS, the Trust will notify the Auction Agent of the amount
to be so included at least five Business Days prior to the Auction Date on which
the Applicable Rate for such dividend is to be  established.  The Trust may also
include  such income in a dividend  on shares of a series of APS without  giving
advance  notice  thereof if it increases  the dividend by an  additional  amount
calculated  as if such  income  was a  Retroactive  Taxable  Allocation  and the
additional  amount  was an  Additional  Dividend,  provided  that the Trust will
notify  the  Auction  Agent of the  additional  amounts to be  included  in such
dividend at least five Business Days prior to the  applicable  Dividend  Payment
Date.

      (g) No fractional shares of APS shall be issued.

      3. LIQUIDATION RIGHTS. Upon any liquidation,  dissolution or winding up of
the Trust,  whether  voluntary or involuntary,  the Holders shall be entitled to
receive,  out  of  the  assets  of  the  Trust  available  for  distribution  to
shareholders,  before any distribution or payment is made upon any Common Shares
or any other shares of beneficial  interest  ranking  junior in right of payment
upon  liquidation to the APS, the sum of $25,000 per share plus  accumulated but
unpaid  dividends  (whether  or not earned or  declared)  thereon to the date of
distribution,  and after such  payment the Holders  will be entitled to no other
payments other than  Additional  Dividends as provided in paragraph 2(e) hereof.
If upon any  liquidation,  dissolution  or winding up of the Trust,  the amounts
payable  with  respect to the APS and any other  Outstanding  class or series of
Preferred  Shares of the Trust  ranking  on a parity  with the APS as to payment
upon liquidation are not paid in full, the Holders and the holders of such other
class or  series  will  share  ratably  in any such  distribution  of  assets in
proportion to the  respective  preferential  amounts to which they are entitled.
After payment of the full amount of the  liquidating  distribution to which they
are entitled,  the Holders will not be entitled to any further  participation in
any distribution of assets by the Trust except for any Additional  Dividends.  A
consolidation,  merger or statutory share exchange of the Trust with or into any
other Trust or entity or a sale,  whether for cash, shares of stock,  securities
or  properties,  of all or  substantially  all or any part of the  assets of the
Trust  shall not be deemed or  construed  to be a  liquidation,  dissolution  or
winding up of the Trust.

      4.  REDEMPTION.  (a) Shares of APS shall be redeemable by the Trust as
provided below:

            (i) To the  extent  permitted  under the 1940 Act and  Massachusetts
      law,  upon  giving a Notice of  Redemption,  the Trust at its  option  may
      redeem shares of APS, in whole or in part, out of funds legally  available
      therefor,  at the  Optional  Redemption  Price per share,  on any Dividend
      Payment Date;  provided that no share of APS may be redeemed at the option
      of the Trust  during (A) the Initial  Dividend  Period  with  respect to a
      series of shares or (B) a Non-Call  Period to which such share is subject.
      In  addition,  holders  of APS which are  redeemed  shall be  entitled  to
      receive Additional  Dividends to the extent provided herein. The Trust may
      not give a Notice of  Redemption  relating  to an optional  redemption  as
      described in this  paragraph  4(a)(i)  unless,  at the time of giving such
      Notice of  Redemption,  the Trust has available  Deposit  Securities  with
      maturity or tender dates not later than the day preceding  the  applicable
      redemption date and having a value not less than the amount due to Holders
      by  reason of the  redemption  of their  shares of APS on such  redemption
      date.

            (ii)  The  Trust  shall  redeem,  out  of  funds  legally  available
      therefor,  at the Mandatory  Redemption Price per share,  shares of APS to
      the extent permitted under the 1940 Act and  Massachusetts  law, on a date
      fixed by the  Board of  Trustees,  if the  Trust  fails  to  maintain  S&P
      Eligible  Assets with an  aggregate  Discounted  Value equal to or greater
      than the APS Basic Maintenance  Amount as provided in paragraph 7(a) or to
      satisfy the 1940 Act APS Asset  Coverage  as  provided in  paragraph 6 and
      such failure is not cured on or before the APS Basic Maintenance Cure Date
      or the 1940 Act Cure  Date  (herein  collectively  referred  to as a "Cure
      Date"), as the case may be. In addition,  holders of APS so redeemed shall


                                       15
<PAGE>

      be entitled to receive Additional Dividends to the extent provided herein.
      The number of shares of APS to be redeemed shall be equal to the lesser of
      (i) the minimum number of shares of APS the redemption of which, if deemed
      to have occurred  immediately prior to the opening of business on the Cure
      Date,  together  with all  shares of other  Preferred  Shares  subject  to
      redemption  or  retirement,  would result in the Trust having S&P Eligible
      Assets with an aggregate Discounted Value equal to or greater than the APS
      Basic  Maintenance  Amount  or  satisfaction  of the  1940  Act APS  Asset
      Coverage,  as the case may be, on such Cure Date (provided  that, if there
      is no such minimum  number of shares of APS and shares of other  Preferred
      Shares the  redemption of which would have such result,  all shares of APS
      and shares of other Preferred Shares then Outstanding  shall be redeemed),
      and (ii) the maximum number of shares of APS,  together with all shares of
      other  Preferred  Shares subject to redemption or retirement,  that can be
      redeemed out of funds  expected to be legally  available  therefor on such
      redemption date. In determining the number of shares of APS required to be
      redeemed in accordance  with the  foregoing,  the Trust shall allocate the
      number  required to be redeemed which would result in the Trust having S&P
      Eligible  Assets with an  aggregate  Discounted  Value equal to or greater
      than the APS Basic Maintenance  Amount or satisfaction of the 1940 Act APS
      Asset  Coverage,  as the case may be, pro rata among  shares of APS of all
      series,  Other  APS and  other  Preferred  Shares  subject  to  redemption
      pursuant  to  provisions  similar  to those  contained  in this  paragraph
      4(a)(ii);  provided  that,  shares of APS which may not be redeemed at the
      option of the Trust due to the designation of a Non-Call Period applicable
      to such  shares (A) will be subject to  mandatory  redemption  only to the
      extent that other shares are not available to satisfy the number of shares
      required to be  redeemed  and (B) will be selected  for  redemption  in an
      ascending order of outstanding number of days in the Non-Call Period (with
      shares with the lowest number of days to be redeemed  first) and by lot in
      the  event of  shares  having  an equal  number  of days in such  Non-Call
      Period.  The Trust shall effect such redemption on a Business Day which is
      not later than 35 days after such Cure Date, except that if the Trust does
      not have funds legally available for the redemption of all of the required
      number of shares of APS and  shares of other  Preferred  Shares  which are
      subject to mandatory redemption or the Trust otherwise is unable to effect
      such  redemption  on or prior to 35 days after  such Cure Date,  the Trust
      shall  redeem  those  shares  of APS  which it is  unable to redeem on the
      earliest  practicable  date on which it is able to effect such  redemption
      out of funds legally available therefor.

      (b)  Notwithstanding any other provision of this paragraph 4, no shares of
APS may be redeemed pursuant to paragraph 4(a)(i) of Article VIII,  Section 2 of
these  Amended  By-Laws  (i) unless all  dividends  in arrears on all  remaining
outstanding   shares   of   Parity   Shares   shall   have  been  or  are  being
contemporaneously  paid or  declared  and set  apart  for  payment  and  (ii) if
redemption  thereof would result in the Trust's failure to maintain S&P Eligible
Assets with an aggregate Discounted Value equal to or greater than the APS Basic
Maintenance  Amount. In the event that less than all the outstanding shares of a
series of APS are to be redeemed  and there is more than one Holder,  the shares
of that  series of APS to be  redeemed  shall be  selected  by lot or such other
method as the Trust shall deem fair and equitable.

      (c) Whenever shares of APS are to be redeemed, the Trust, not less than 17
nor more than 30 days  prior to the date  fixed  for  redemption,  shall  mail a
notice ("Notice of Redemption") by first-class  mail,  postage prepaid,  to each
Holder of shares of APS to be redeemed and to the Auction Agent. The Trust shall
cause the Notice of  Redemption to also be published in the eastern and national
editions of The Wall Street  Journal.  The Notice of Redemption  shall set forth
(i) the  redemption  date,  (ii) the amount of the redemption  price,  (iii) the
aggregate number of shares of APS of such series to be redeemed,  (iv) the place
or places where shares of APS of such series are to be  surrendered  for payment
of the  redemption  price,  (v) a statement  that  dividends on the shares to be
redeemed shall cease to accumulate on such  redemption date (except that holders
may be entitled to Additional Dividends) and (vi) the provision of these Amended
By-Laws  pursuant  to which  such  shares are being  redeemed.  No defect in the
Notice of Redemption or in the mailing or  publication  thereof shall affect the
validity of the redemption proceedings, except as required by applicable law.

      If the  Notice of  Redemption  shall  have been  given as  aforesaid  and,
concurrently  or  thereafter,  the Trust shall have  deposited in trust with the
Auction Agent, or segregated in an account at the Trust's custodian bank for the
benefit of the Auction Agent,  Deposit Securities (with a right of substitution)
having  an  aggregate  Discounted  Value  (utilizing  in the  case of S&P an S&P
Exposure  Period of 22 Business  Days) equal to the  redemption  payment for the
shares  of APS as to  which  such  Notice  of  Redemption  has been  given  with


                                       16
<PAGE>

irrevocable  instructions  and  authority  to pay the  redemption  price  to the
Holders  of such  shares,  then  upon the date of such  deposit  or,  if no such
deposit is made,  then upon such date  fixed for  redemption  (unless  the Trust
shall default in making the  redemption  payment),  all rights of the Holders of
such  shares as  shareholders  of the Trust by reason of the  ownership  of such
shares will cease and terminate  (except  their right to receive the  redemption
price in respect thereof and any Additional  Dividends,  but without  interest),
and such  shares  shall no  longer  be deemed  outstanding.  The Trust  shall be
entitled to receive,  from time to time, from the Auction Agent the interest, if
any, on such Deposit Securities  deposited with it and the Holders of any shares
so redeemed shall have no claim to any of such  interest.  In case the Holder of
any shares so called for redemption  shall not claim the redemption  payment for
his shares  within  one year after the date of  redemption,  the  Auction  Agent
shall,  upon demand,  pay over to the Trust such amount remaining on deposit and
the Auction  Agent shall  thereupon  be  relieved of all  responsibility  to the
Holder of such shares called for  redemption  and such Holder  thereafter  shall
look only to the Trust for the redemption payment.

      5.  VOTING  RIGHTS.  (a)  General.  Except as  otherwise  provided  in the
Declaration of Trust or Amended  By-Laws,  each Holder of shares of APS shall be
entitled to one vote for each share held on each matter  submitted  to a vote of
shareholders  of the Trust,  and the holders of outstanding  shares of Preferred
Shares,  including  APS, and of shares of Common Shares shall vote together as a
single class;  provided  that, at any meeting of the  shareholders  of the Trust
held for the  election  of  trustees,  the  holders  of  outstanding  shares  of
Preferred Shares, including APS, shall be entitled, as a class, to the exclusion
of the  holders of all other  securities  and  classes  of capital  stock of the
Trust, to elect two trustees of the Trust. Subject to paragraph 5(b) hereof, the
holders of  outstanding  shares of capital  stock of the  Trust,  including  the
holders of outstanding  shares of Preferred  Shares,  including APS, voting as a
single class, shall elect the balance of the trustees.

      (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 of  Trustees  shall be  automatically  increased  by the
smallest number that, when added to the two directors elected exclusively by the
holders of shares of Preferred Shares,  would constitute a majority of the Board
of Trustees as so increased by such smallest  number;  and the holders of shares
of Preferred  Shares shall be entitled,  voting  separately as one class (to the
exclusion  of the  holders  of all other  securities  and  classes  of shares of
beneficial  interest of the Trust),  to elect such smallest number of additional
trustees,  together  with the two  trustees  that such  holders are in any event
entitled to elect. A Voting Period shall commence:

            (i) if at any time accumulated  dividends  (whether or not earned or
      declared, and whether or not funds are then legally available in an amount
      sufficient  therefor) on the  outstanding  shares of APS equal to at least
      two full years'  dividends  shall be due and unpaid and sufficient cash or
      specified  securities shall not have been deposited with the Auction Agent
      for the payment of such accumulated dividends; or

            (ii) if at any time holders of any other shares of Preferred  Shares
      are  entitled to elect a majority  of the  trustees of the Trust under the
      1940 Act.  Upon the  termination  of a Voting  Period,  the voting  rights
      described in this paragraph 5(b) shall cease, subject always,  however, to
      the  reverting  of such  voting  rights in the  Holders  upon the  further
      occurrence of any of the events described in this paragraph 5(b)

     (c) Right to Vote with  Respect to Certain  Other  Matters.  So long as any
shares of APS are outstanding, the Trust shall not, without the affirmative vote
of the holders of a majority of the shares of Preferred  Shares  Outstanding  at
the time,  voting  separately as one class:  (i) authorize,  create or issue any
class or series of shares of beneficial interest ranking prior to the APS or any
other  series of  Preferred  Shares with  respect to payment of dividends or the
distribution  of assets  on  liquidation,  or (ii)  amend,  alter or repeal  the
provisions of the Declaration of Trust, whether by


                                       17
<PAGE>

merger,   consolidation   or  otherwise,  so  as  to adversely affect any of the
contract  rights  expressly set forth in the  Declaration of Trust of holders of
shares of APS or any other Preferred  Shares.  To the extent permitted under the
1940 Act,  in the event  shares of more than one series of APS are  outstanding,
the Trust  shall not  approve any of the actions set forth in clause (i) or (ii)
which  adversely  affects  the  contract  rights  expressly  set  forth  in  the
Declaration of Trust of a Holder of shares of a series of APS  differently  than
those of a Holder of shares of any other  series of APS without the  affirmative
vote of the  holders of at least a majority  of the shares of APS of each series
adversely  affected and  outstanding at such time (each such adversely  affected
series voting  separately  as a class).  The Trust shall notify S&P ten Business
Days prior to any such vote  described  in clause  (i) or (ii).  Unless a higher
percentage is provided for under the Declaration of Trust,  the affirmative vote
of the  holders of a majority of the  outstanding  shares of  Preferred  Shares,
including APS,  voting  together as a single class,  will be required to approve
any  plan  of  reorganization   (including  bankruptcy   proceedings)  adversely
affecting such shares or any action  requiring a vote of security  holders under
Section  13(a) of the 1940 Act. The class vote of holders of shares of Preferred
Shares,  including  APS,  described  above will in each case be in addition to a
separate vote of the requisite  percentage of shares of Common Shares and shares
of Preferred Shares,  including APS, voting together as a single class necessary
to authorize the action in question.

      (d) Voting Procedures.

      (i) As soon as  practicable  after the accrual of any right of the holders
of shares of  Preferred  Shares to elect  additional  trustees as  described  in
paragraph 5(b) above, the Trust shall call a special meeting of such holders and
instruct  the  Auction  Agent to mail a notice of such  special  meeting to such
holders,  such  meeting  to be held not less than 10 nor more than 20 days after
the date of mailing of such  notice.  If the Trust  fails to send such notice to
the Auction Agent or if the Trust does not call such a special  meeting,  it may
be called by any such holder on like notice. The record date for determining the
holders  entitled to notice of and to vote at such special  meeting shall be the
close of  business on the fifth  Business  Day  preceding  the day on which such
notice is mailed.  At any such special meeting and at each meeting held during a
Voting Period, such Holders, voting together as a class (to the exclusion of the
holders of all other securities and classes of shares of beneficial  interest of
the Trust),  shall be entitled to elect the number of  directors  prescribed  in
paragraph 5(b) above. At any such meeting or adjournment  thereof in the absence
of a quorum, a majority of such holders present in person or by proxy shall have
the power to adjourn the meeting without  notice,  other than by an announcement
at the meeting, to a date not more than 120 days after the original record date.

      (ii) For purposes of determining any rights of the Holders to vote on  any
matter  or  the  number  of shares required to constitute a quorum, whether such
right is created by  these Amended By-Laws,  by  the  other  provisions  of  the
Declaration of Trust,   by statute or otherwise,   a  share  of APS which is not
Outstanding shall not be counted.

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

      (iv) Simultaneously with  the expiration  of a Voting Period,   the  terms
of  office  of  the  additional  trustees  elected by the Holders and holders of
other  Preferred  Shares  pursuant to  paragraph 5(b) above shall terminate, the
remaining trustees  shall constitute  the trustees  of the  Trust and the voting
rights  of the  Holders and  such other  holders to  elect additional   trustees
pursuant to paragraph  5(b) above shall cease,  subject to the provisions of the
last sentence of paragraph 5(b).

      (e) Exclusive  Remedy.  Unless  otherwise  required by law, the Holders of
shares  of APS  shall  not have any  rights  or  preferences  other  than  those
specifically  set forth  herein.  The  Holders  of  shares of APS shall  have no
preemptive  rights or rights to cumulative  voting.  In the event that the Trust
fails to pay any  dividends  on the shares of APS, the  exclusive  remedy of the
Holders  shall be the right to vote for trustees  pursuant to the  provisions of
this paragraph 5.

      (f) Notification to S&P and Moody's. In the event a vote of Holders of APS
is required  pursuant to the  provisions  of Section  13(a) of the 1940 Act, the
Trust shall,  not later than ten  Business  Days prior to the date on which such
vote is to be taken,  notify S&P that such vote is to be taken and the nature of
the action  with  respect to which such vote is to be taken and,  not later than
ten Business Days after the date on which such vote is taken,  notify S&P of the
result of such vote.

      6. 1940 ACT APS ASSET COVERAGE.  The Trust shall maintain,  as of the last
Business  Day of each month in which any share of APS is  outstanding,  the 1940
Act APS Asset Coverage.

      7. APS BASIC  MAINTENANCE  AMOUNT.  (a) The Trust shall maintain,  on each
Valuation Date, and shall verify to its  satisfaction  that it is maintaining on
such Valuation  Date S&P Eligible  Assets having an aggregate  Discounted  Value
equal to or greater than the APS Basic Maintenance  Amount.  Upon any failure to
maintain the required  Discounted  Value, the Trust will use its best efforts to
alter the  composition  of its  portfolio to retain a Discounted  Value at least
equal  to the  APS  Basic  Maintenance  Amount  on or  prior  to the  APS  Basic
Maintenance Cure Date.

      (b) On or before 5:00 p.m.,  New York City time, on the third Business Day
after a  Valuation  Date on which  the  Trust  fails to  satisfy  the APS  Basic
Maintenance  Amount,  the Trust shall complete and deliver to the Auction Agent,
and S&P, a complete APS Basic Maintenance Report as of the date of such failure,
which will be deemed to have been  delivered to the Auction Agent if the Auction
Agent  receives  a copy or  telecopy,  telex or other  electronic  transcription
thereof and on the same day the Trust mails to the Auction Agent for delivery on
the next Business Day the complete APS Basic Maintenance  Report. The Trust will
deliver an APS Basic  Maintenance  Report to the  Auction  Agent and S&P,  on or
before  5:00  p.m.,  New York  City  time,  on the  third  Business  Day after a
Valuation  Date on which the Trust cures its failure to  maintain  S&P  Eligible
Assets,  with an  aggregate  Discounted  Value equal to or greater  than the APS
Basic  Maintenance  Amount or on which the Trust fails to maintain  S&P Eligible
Assets,  with  an  aggregate  Discounted  Value  which  exceeds  the  APS  Basic
Maintenance  Amount by 5% or more.  The Trust  will  also  deliver  an APS Basic
Maintenance  Report to the Auction Agent and S&P as of each Quarterly  Valuation
Date on or before the third  Business Day after such date.  Additionally,  on or
before 5:00 p.m.,  New York City time, on the third Business Day after the first
day  of a  Special  Dividend  Period,  the  Trust  will  deliver  an  APS  Basic
Maintenance  Report to S&P and the Auction  Agent.  The Trust shall also provide
S&P with an APS Basic Maintenance  Report when specifically  requested by S&P. A
failure  by the Trust to  deliver  an APS Basic  Maintenance  Report  under this
paragraph 7(b) shall be deemed to be delivery of an APS Basic Maintenance Report
indicating  the  Discounted  Value for S&P Eligible  Assets of the Trust is less
than the APS  Basic  Maintenance  Amount,  as of the  relevant  Valuation  Date.

      (c) Within ten  Business  Days after the date of  delivery of an APS Basic
Maintenance  Report in  accordance  with  paragraph  7(b)  above  relating  to a
Quarterly Valuation 50 Date, the Independent  Accountant will confirm in writing
to the Auction Agent and S&P (i) the  mathematical  accuracy of the calculations
reflected  in such  Report  (and in any  other  APS  Basic  Maintenance  Report,
randomly selected by the Independent Accountant, that was delivered by the Trust
during the quarter ending on such Quarterly  Valuation Date), (ii) that, in such
Report (and in such randomly  selected Report),  the Trust correctly  determined
the assets of the Trust which  constitute S&P Eligible  Assets at such Quarterly
Valuation  Date in accordance  with these Amended  By-Laws,  (iii) that, in such
Report (and in such randomly selected Report),  the Trust determined whether the
Trust had, at such Quarterly Valuation Date (and at the Valuation Date addressed
in such randomly selected Report) in accordance with these Amended By-Laws,  S&P
Eligible Assets of an aggregate Discounted Value at least equal to the APS Basic
Maintenance   Amount,  (iv)  with  respect  to  the  S&P  ratings  on  Municipal
Obligations,  the issuer name, issue size and coupon rate listed in such Report,
that the Independent  Accountant has requested that S&P verify such  information
and the  Independent  Accountant  shall  provide a listing  in its letter of any
differences,  (v) with respect to the Moody's ratings on Municipal  Obligations,
the issuer  name,  issue size and coupon rate listed in such  Report,  that such
information  has been verified by Moody's (in the event such  information is not
verified by Moody's,  the  Independent  Accountant  will inquire of Moody's what
such  information  is, and provide a listing in its letter of any  differences),
(vi) with  respect  to the bid or mean  price (or such  alternative  permissible
factor used in  calculating  the Market Value)  provided by the custodian of the
Trust's  assets to the Trust for purposes of valuing  securities  in the Trust's
portfolio,  the Independent  Accountant has traced the price used in such Report
to the bid or mean  price  listed in such  Report as  provided  to the Trust and
verified that such  information  agrees (in the event such  information does not
agree,  the Independent  Accountant will provide a listing in its letter of such
differences)  and (vii) with respect to such  confirmation to Moody's,  that the
Trust has satisfied the  requirements of paragraph 8(b) of these Amended By-Laws
(such   confirmation   is  herein  called  the   "Accountant's   Confirmation").

      (d) Within ten  Business  Days after the date of  delivery  to the Auction
Agent and S&P of an APS Basic  Maintenance  Report in accordance  with paragraph
7(b) above  relating to any Valuation Date on which the Trust failed to maintain
S&P Eligible Assets with an aggregate  Discounted Value equal to or greater than


                                       19
<PAGE>

the APS Basic Maintenance Amount, and relating to the APS Basic Maintenance Cure
Date with respect to such failure,  the  Independent  Accountant will provide to
the  Auction  Agent and S&P an  Accountant's  Confirmation  as to such APS Basic
Maintenance Report.

      (e) If any Accountant's  Confirmation  delivered  pursuant to subparagraph
(c) or (d) of this  paragraph  7 shows  that an error  was made in the APS Basic
Maintenance  Report for a particular  Valuation Date for which such Accountant's
Confirmation  as  required  to be  delivered,  or shows  that a lower  aggregate
Discounted  Value for the aggregate of all S&P Eligible  Assets of the Trust was
determined by the Independent Accountant,  the calculation or determination made
by such  Independent  Accountant  shall be final  and  conclusive  and  shall be
binding on the Trust, and the Trust shall  accordingly amend and deliver the APS
Basic Maintenance Report to the Auction Agent and S&P promptly following receipt
by the Trust of such Accountant's Confirmation.

      (f) On or before 5:00 p.m.,  New York City time, on the first Business Day
after the Date of Original  Issue of the shares of APS, the Trust will  complete
and deliver to S&P an APS Basic  Maintenance  Report as of the close of business
on such  Date of  Original  Issue.  Within  five  Business  Days of such Date of
Original Issue,  the  Independent  Accountant will confirm in writing to S&P (i)
the mathematical accuracy of the calculations  reflected in such Report and (ii)
that the aggregate  Discounted  Value of S&P Eligible Assets  reflected  thereon
equals or exceeds the APS Basic Maintenance Amount reflected  thereon.  Also, on
or before 5:00 p.m.,  New York City time, on the first Business Day after shares
of Common  Shares are  repurchased  by the Trust,  the Trust will  complete  and
deliver to S&P an APS Basic  Maintenance  Report as of the close of  business on
such date that Common Shares is repurchased.

      8.  CERTAIN OTHER RESTRICTIONS AND REQUIREMENTS.

      (a) For so long as any shares of APS are rated by S&P,  the Trust 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 S&P that  engaging in such  transactions  will not impair the
ratings  then  assigned  to the shares of APS by S&P,  except that the Trust may
purchase or sell futures  contracts based on the Bond Buyer Municipal Bond Index
(the  "Municipal  Index") or United States  Treasury  Bonds or Notes  ("Treasury
Bonds")  and write,  purchase  or sell put and call  options  on such  contracts
(collectively,   "S&P   Hedging   Transactions"),   subject  to  the   following
limitations:

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

      (ii) the Trust will not  engage in any S&P  Hedging  Transaction  based on
Treasury Bonds (other than Closing  Transactions) which would cause the Trust at
the time of such  transaction to own or have sold the lesser of (A)  outstanding
futures  contracts  based on Treasury Bonds and on the Municipal Index exceeding
in number 25% of the  quotient of the Market  Value of the Trust's  total assets
divided by $100,000 ($200,000 in the case of the two-year United States Treasury
Note) or (B) outstanding  futures contracts based on Treasury Bonds exceeding in
number 10% of the average  number of daily  traded  futures  contracts  based on
Treasury Bonds in the 30 days  preceding the time of effecting such  transaction
as reported by The Wall Street Journal;-----------------------

      (iii)  the Trust  will  engage in  Closing  Transactions  to close out any
outstanding futures contract which the Trust owns or has sold or any outstanding
option  thereon  owned by the Trust in the event (A) the Trust does not have S&P
Eligible Assets with an aggregate  Discounted Value equal to or greater than the
APS Basic  Maintenance  Amount on two  consecutive  Valuation  Dates and (B) the
Trust is required to pay  Variation  Margin on the second such  Valuation  Date;


                                       20
<PAGE>

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

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

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

      (d) For so long as  shares of APS are  rated by S&P,  the Trust  will not,
unless it has received written  confirmation from S&P that such action would not
impair the rating then  assigned to shares of APS by S&P (i) borrow money except
for  the  purpose  of  clearing  transactions  in  portfolio  securities  (which
borrowings shall under any circumstances be limited to the lesser of $10 million
and an amount equal to 5% of the Market Value of the Trust's  assets at the time
of such borrowings and which  borrowings  shall be repaid within 60 days and not
be extended or renewed and shall not cause the aggregate Discounted Value of S&P
Eligible Assets to be less than the APS Basic Maintenance  Amount),  (ii) engage
in short sales of securities, (iii) lend any securities, (iv) issue any class or
series of stock ranking prior to or on a parity with the APS with respect to the
payment of dividends or the distribution of assets upon dissolution, liquidation
or winding up of the Trust, (v) reissue any APS previously purchased or redeemed
by the Trust,  (vi) merge or consolidate into or with any other Trust or entity,
(vii)  change  the  Pricing  Service  or  (viii)  engage in  reverse  repurchase
agreements.

      9. NOTICE.  All notices or communications,  unless otherwise  specified in
the Amended By-Laws of the Trust or these Amended By-Laws, shall be sufficiently
given if in  writing  and  delivered  in person or mailed by  first-class  mail,
postage  prepaid.  Notice  shall  be  deemed  given on the  earlier  of the date
received   or  the  date  seven  days  after   which  such   notice  is  mailed.

determined  based on (i) the credit rating  assigned on such date to such shares
by S&P (or if S&P shall not make such rating  available,  the equivalent of such


                                       21

rating by a  Substitute  Rating  Agency) and (ii) whether the Trust has provided
notification  to the  Auction  Agent  prior  to  the  Auction  establishing  the

Applicable  Rate for any  dividend  pursuant to  paragraph  2(f) hereof that net
capital  gains or other  taxable  income will be  included  in such  dividend on

      The Trust  shall take all  reasonable  action  necessary  to enable S&P to
provide a rating  for the APS.  If S&P  shall not make such a rating  available,
PaineWebber  Incorporated or its affiliates and successors,  after  consultation
with  the  Trust,  shall  select  a  nationally  recognized  statistical  rating
organization to act as a Substitute Rating Agency.

      (b) Orders by Beneficial Owners, Potential Beneficial Owners, Existing
Holders and Potential Holders.

      (i)  Unless  otherwise  permitted  by the  Trust,  Beneficial  Owners  and
Potential  Beneficial  Owners may only  participate  in Auctions  through  their
Broker-Dealers.  Broker-Dealers  will  submit  the  Orders  of their  respective
customers  who are  Beneficial  Owners and  Potential  Beneficial  Owners to the
Auction Agent,  designating  themselves as Existing Holders in respect of shares
subject to Orders submitted or deemed submitted to them by Beneficial Owners and
as Potential Holders in respect of shares subject to Orders submitted to them by
Potential  Beneficial Owners. A Broker-Dealer may also hold shares of APS in its
own account as a Beneficial Owner. A Broker-Dealer may thus submit Orders to the
Auction  Agent  as a  Beneficial  Owner  or a  Potential  Beneficial  Owner  and
therefore participate in an Auction as an Existing Holder or Potential Holder on
behalf of both itself and its customers.  On or prior to the Submission Deadline
on each Auction Date:

     A. each Beneficial Owner may submit to its Broker-Dealer information as to:

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


                                       22
<PAGE>

            (2) the number of  Outstanding  shares,  if any, of APS held by such
      Beneficial  Owner which such Beneficial Owner desires to continue to hold,
      provided that the Applicable Rate for the next succeeding  Dividend Period
      shall  not be less than the rate per annum  specified  by such  Beneficial
      Owner; and/or

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

      (B) each Broker-Dealer,  using a list of Potential  Beneficial Owners that
shall be  maintained  in good faith for the purpose of  conducting a competitive
Auction,  shall contact Potential Beneficial Owners,  including Persons that are
not  Beneficial  Owners,  on such list to  determine  the number of  Outstanding
shares,  if any, of APS which each such  Potential  Beneficial  Owner  offers to
purchase,  provided that the Applicable  Rate for the next  succeeding  Dividend
Period  shall not be less than the rate per annum  specified  by such  Potential
Beneficial Owner.

      For the  purposes  hereof,  the  communication  by a  Beneficial  Owner or
Potential  Beneficial  Owner  to a  Broker-Dealer,  or  the  communication  by a
Broker-Dealer  acting for its own account to the Auction  Agent,  of information
referred  to in clause  (A) or (B) of this  paragraph  10(b)(i)  is  hereinafter
referred  to  as an  "Order"  and  each  Beneficial  Owner  and  each  Potential
Beneficial  Owner  placing an Order,  including a  Broker-Dealer  acting in such
capacity for its own account, is hereinafter referred to as a "Bidder"; an Order
containing  the  information  referred  to in clause  (A)(1)  of this  paragraph
10(b)(i) is hereinafter  referred to as a "Hold Order";  an Order containing the
information  referred to in clause (A)(2) or (B) of this  paragraph  10(b)(i) is
hereinafter  referred to as a "Bid";  and an Order  containing  the  information
referred to in clause (A)(3) of this paragraph 10(b)(i) is hereinafter  referred
to as a "Sell Order". Inasmuch as a Broker-Dealer  participates in an Auction as
an Existing  Holder or a Potential  Holder only to represent  the interests of a
Beneficial Owner or Potential  Beneficial Owner,  whether it be its customers or
itself,  all discussion  herein  relating to the  consequences of an Auction for
Existing Holders and Potential Holders also applies to the underlying beneficial
ownership interests represented.

      (ii) (A) A Bid by an Existing Holder shall constitute an irrevocable offer
to sell:

      (1)the number of  Outstanding  shares of APS  specified in such Bid if the
         Applicable  Rate determined on such Auction Date shall be less than the
         rate per annum  specified  in such Bid;  or (1) such number or a lesser
         number of  Outstanding  shares of APS to be  determined as set forth in
         paragraph 10(e)(i)(D) if the Applicable Rate determined on such Auction
         Date shall be equal to the rate per annum specified therein; or

      (2)a lesser  number of  Outstanding  shares of APS to be determined as set
         forth in paragraph  10(e)(ii)(C) if such specified rate per annum shall
         be higher than the Maximum Applicable Rate and Sufficient Clearing Bids
         do not exist.

      (B) A Sell Order by an Existing  Holder shall  constitute  an  irrevocable
offer to sell:

            (1) the number of Outstanding shares of APS specified  in such  Sell
      Order; or

            (2) such number or a lesser number of  Outstanding  shares of APS to
      be  determined  as set  forth  in  paragraph  10(e)(ii)(C)  if  Sufficient
      Clearing Bids do not exist.

      (C) A Bid by a Potential Holder shall  constitute an irrevocable  offer to
purchase:

            (1) the number of Outstanding shares of APS specified in such Bid if
      the Applicable  Rate  determined on such Auction Date shall be higher than
      the rate per annum specified in such Bid; or

            (2) such number or a lesser number of  Outstanding  shares of APS to
      be determined as set forth in paragraph 10(e)(i)(E) if the Applicable Rate
      determined  on such  Auction  Date  shall be  equal to the rate per  annum
      specified therein.

            (c) Submission of Orders by Broker-Dealers to Auction Agent

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

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

            (B) the aggregate  number of Outstanding  shares of APS that are the
      subject of such Order;

            (C) to the extent that such Bidder is an Existing Holder:

                  (1)the number of  Outstanding  shares,  if any, of APS subject
                     to any Hold Order placed by such Existing Holder;

                  (2)the number of  Outstanding  shares,  if any, of APS subject
                     to any Bid placed by such Existing  Holder and the rate per
                     annum specified in such Bid; and

                  (3)the number of  Outstanding  shares,  if any, of APS subject
                     to any Sell Order placed by such Existing Holder; and

            (D) to the extent such Bidder is a  Potential  Holder,  the rate per
      annum specified in such Potential Holder's Bid.

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

      (iii) If an Order or Orders covering all of the Outstanding  shares of APS
held by an Existing  Holder are not  submitted to the Auction Agent prior to the
Submission  Deadline,  the Auction Agent shall deem a Hold Order (in the case of
an Auction relating to a Dividend Period which is not a Special Dividend Period)
and a Sell  Order (in the case of an  Auction  relating  to a  Special  Dividend
Period) to have been  submitted on behalf of such Existing  Holder  covering the
number of Outstanding shares of APS held by such Existing Holder and not subject
to Orders submitted to the Auction Agent.

      (iv) If one or more Orders on behalf of an Existing Holder covering in the
aggregate  more  than  the  number  of  Outstanding  shares  of APS held by such
Existing  Holder  are  submitted  to the  Auction  Agent,  such  Order  shall be
considered valid as follows and in the following order of priority:

            (A) any Hold Order submitted on behalf of such Existing Holder shall
      be considered  valid up to and including the number of Outstanding  shares
      of APS held by such Existing  Holder;  provided that if more than one Hold
      Order is  submitted  on behalf of such  Existing  Holder and the number of
      shares  of  APS  subject  to  such  Hold  Orders  exceeds  the  number  of
      Outstanding  shares of APS held by such  Existing  Holder,  the  number of
      shares of APS  subject to each of such Hold  Orders  shall be reduced  pro
      rata so that such Hold Orders,  in the  aggregate,  will cover exactly the
      number of Outstanding shares of APS held by such Existing Holder;

            (B) any Bids  submitted on behalf of such  Existing  Holder shall be
      considered  valid,  in the ascending order of their  respective  rates per
      annum if more than one Bid is submitted on behalf of such Existing Holder,
      up to and including the excess of the number of Outstanding  shares of APS
      held by such  Existing  Holder over the number of shares of APS subject to
      any Hold Order  referred to in paragraph  10(c)(iv)(A)  above (and if more


                                       24
<PAGE>

      than one Bid  submitted on behalf of such  Existing  Holder  specifies the
      same rate per annum and together they cover more than the remaining number
      of shares  that can be the  subject  of valid Bids  after  application  of
      paragraph  10(c)(iv)(A)  above  and  of  the  foregoing  portion  of  this
      paragraph 10(c)(iv)(B) to any Bid or Bids specifying a lower rate or rates
      per  annum,  the  number of shares  subject  to each of such Bids shall be
      reduced pro rata so that such Bids, in the  aggregate,  cover exactly such
      remaining number of shares);  and the number of shares, if any, subject to
      Bids not valid under this paragraph  10(c)(iv)(B)  shall be treated as the
      subject of a Bid by a Potential Holder; and

            (C) any Sell Order shall be considered valid up to and including the
      excess of the number of  Outstanding  shares of APS held by such  Existing
      Holder over the number of shares of APS subject to Hold Orders referred to
      in paragraph 10(c)(iv)(A) and Bids referred to in paragraph  10(c)(iv)(B);
      provided  that if more than one Sell Order is  submitted  on behalf of any
      Existing  Holder  and the  number of shares  of APS  subject  to such Sell
      Orders is greater than such excess, the number of shares of APS subject to
      each of such  Sell  Orders  shall be  reduced  pro rata so that  such Sell
      Orders, in the aggregate,  cover exactly the number of shares of APS equal
      to such excess.

      (v) If more than one Bid is submitted on behalf of any  Potential  Holder,
each Bid submitted shall be a separate Bid with the rate per annum and number of
shares of APS therein specified.

      (vi) Any Order submitted by a Beneficial  Owner as a Potential  Beneficial
Owner to its Broker-Dealer, or by a Broker-Dealer to the Auction Agent, prior to
the Submission Deadline on any Auction Date shall be irrevocable.

      (d) Determination of Sufficient Clearing Bids, Winning Bid Rate and
Applicable Rate.

      (i) Not earlier than the  Submission  Deadline on each Auction  Date,  the
Auction Agent shall assemble all Orders  submitted or deemed  submitted to it by
the  Broker-Dealers  (each  such Order as  submitted  or deemed  submitted  by a
Broker-Dealer  being  hereinafter  referred to individually as a "Submitted Hold
Order", a "Submitted Bid" or a "Submitted Sell Order", as the case may be, or as
a "Submitted Order") and shall determine:

            (A) the excess of the total number of Outstanding shares of APS over
      the number of Outstanding  shares of APS that are the subject of Submitted
      Hold Orders (such excess being  hereinafter  referred to as the "Available
      APS");

            (B) from the  Submitted  Orders  whether  the number of  Outstanding
      shares of APS that are the subject of Submitted Bids by Potential  Holders
      specifying  one or more rates per annum equal to or lower than the Maximum
      Applicable Rate exceeds or is equal to the sum of:

            (1) the number of Outstanding  shares of APS that are the subject of
            Submitted Bids by Existing Holders  specifying one or more rates per
            annum higher than the Maximum Applicable Rate, and

            (2) the  number of  Outstanding  shares of APS that are  subject  to
            Submitted Sell Orders (if such excess or such equality exists (other
            than because the number of  Outstanding  shares of APS in clause (1)
            above  and  this  clause  (2)  are  each  zero  because  all  of the
            Outstanding shares of APS are the subject of Submitted Hold Orders),
            such Submitted Bids by Potential Holders being hereinafter  referred
            to collectively as "Sufficient Clearing Bids"); and

      (C) if Sufficient Clearing Bids exist, the lowest rate per annum specified
in the Submitted Bids (the "Winning Bid Rate") that if:

            (1) each Submitted Bid from Existing Holders  specifying the Winning
      Bid Rate and all other  Submitted  Bids from Existing  Holders  specifying
      lower rates per annum were rejected,  thus entitling such Existing Holders
      to  continue  to hold  the  shares  of APS that  are the  subject  of such
      Submitted Bids, and

            (2) each Submitted Bid from Potential Holders specifying the Winning
      Bid Rate and all other  Submitted Bids from Potential  Holders  specifying
      lower rates per annum were accepted,  thus entitling the Potential Holders
      to purchase the shares of APS that are the subject of such Submitted Bids,


                                       25
<PAGE>

      would  result in the  number  of  shares  subject  to all  Submitted  Bids
      specifying  the  Winning Bid Rate or a lower rate per annum being at least
      equal to the Available APS.

            (ii) Promptly  after the Auction  Agent has made the  determinations
      pursuant to paragraph  10(d)(i),  the Auction Agent shall advise the Trust
      of the Maximum  Applicable  Rate and,  based on such  determinations,  the
      Applicable Rate for the next succeeding Dividend Period as follows:

            (A)if Sufficient  Clearing Bids exist,  that the Applicable Rate for
               the next succeeding Dividend Period shall be equal to the Winning
               Bid Rate;

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

            (C)if all of the  Outstanding  shares  of APS  are  the  subject  of
               Submitted Hold Orders,  that the Dividend  Period next succeeding
               the  Auction  shall  automatically  be  the  same  length  as the
               immediately preceding Dividend Period and the Applicable Rate for
               the next succeeding  Dividend Period shall be equal to 40% of the
               Reference  Rate (or 60% of such rate if the  Trust  has  provided
               notification   to  the   Auction   Agent  prior  to  the  Auction
               establishing  the  Applicable  Rate for any dividend  pursuant to
               paragraph  2(f) hereof that net  capital  gains or other  taxable
               income will be included in such dividend on shares of APS) on the
               date of the Auction.

            (e)  Acceptance  and Rejection of Submitted  Bids and Submitted Sell
      Orders and Allocation of Shares. Based on the determinations made pursuant
      to paragraph 10(d)(i),  the Submitted Bids and Submitted Sell Orders shall
      be accepted or rejected and the Auction Agent shall take such other action
      as set forth below:

      (i) If Sufficient  Clearing Bids have been made, subject to the provisions
of paragraph  10(e)(iii) and paragraph  10(e)(iv),  Submitted Bids and Submitted
Sell Orders shall be accepted or rejected in the following order of priority and
all other Submitted Bids shall be rejected:

            (A) the Submitted Sell Orders of Existing  Holders shall be accepted
      and the Submitted Bid of each of the Existing Holders  specifying any rate
      per annum that is higher than the Winning Bid Rate shall be accepted, thus
      requiring each such Existing Holder to sell the Outstanding  shares of APS
      that are the subject of such Submitted Sell Order or Submitted Bid;

            (B) the Submitted Bid of each of the Existing Holders specifying any
      rate per annum that is lower than the Winning Bid Rate shall be  rejected,
      thus  entitling  each  such  Existing  Holder  to  continue  to  hold  the
      Outstanding shares of APS that are the subject of such Submitted Bid;

            (C) the Submitted Bid of each of the  Potential  Holders  specifying
      any rate per  annum  that is lower  than  the  Winning  Bid Rate  shall be
      accepted;

            (D) the Submitted Bid of each of the Existing  Holders  specifying a
      rate per annum that is equal to the  Winning  Bid Rate shall be  rejected,
      thus  entitling  each  such  Existing  Holder  to  continue  to  hold  the
      Outstanding  shares of APS that are the  subject  of such  Submitted  Bid,
      unless  the  number  of  Outstanding  shares  of APS  subject  to all such
      Submitted Bids shall be greater than the number of  Outstanding  shares of
      APS ("Remaining Shares") equal to the excess of the Available APS over the
      number of Outstanding shares of APS subject to Submitted Bids described in
      paragraph  10(e)(i)(B)  and  paragraph  10(e)(i)(C),  in which  event  the
      Submitted  Bids of each such Existing  Holder shall be accepted,  and each
      such Existing Holder shall be required to sell Outstanding  shares of APS,
      but only in an amount  equal to the  difference  between (1) the number of
      Outstanding  shares of APS then held by such  Existing  Holder  subject to
     

                                       26
<PAGE>

      such  Submitted  Bid and (2) the  number  of  shares  of APS  obtained  by
      multiplying  (x) the  number of  Remaining  Shares by (y) a  fraction  the
      numerator of which shall be the number of  Outstanding  shares of APS held
      by such Existing  Holder subject to such Submitted Bid and the denominator
      of which  shall be the sum of the  number  of  Outstanding  shares  of APS
      subject to such  Submitted  Bids made by all such  Existing  Holders  that
      specified a rate per annum equal to the Winning Bid Rate; and

            (E) the Submitted Bid of each of the Potential Holders  specifying a
      rate per annum that is equal to the Winning Bid Rate shall be accepted but
      only in an  amount  equal  to the  number  of  Outstanding  shares  of APS
      obtained by multiplying  (x) the difference  between the Available APS and
      the  number  of  Outstanding  shares  of APS  subject  to  Submitted  Bids
      described in paragraph  10(e)(i)(B),  paragraph  10(e)(i)(C) and paragraph
      10(e)(i)(D)  by (y) a fraction the  numerator of which shall be the number
      of  Outstanding  shares  of APS  subject  to  such  Submitted  Bid and the
      denominator of which shall be the sum of the number of Outstanding  shares
      of APS  subject  to such 74  Submitted  Bids  made by all  such  Potential
      Holders that specified rates per annum equal to the Winning Bid Rate.


      (ii) If  Sufficient  Clearing  Bids have not been made (other than because
all of the  Outstanding  shares of APS are subject to  Submitted  Hold  Orders),
subject to the  provisions of paragraph  10(e)(iii),  Submitted  Orders shall be
accepted or rejected as follows in the following order of priority and all other
Submitted Bids shall be rejected:

            (A) the Submitted Bid of each Existing  Holder  specifying  any rate
      per annum that is equal to or lower than the Maximum Applicable Rate shall
      be rejected,  thus entitling such Existing  Holder to continue to hold the
      Outstanding shares of APS that are the subject of such Submitted Bid;

            (B) the Submitted Bid of each Potential  Holder  specifying any rate
      per annum that is equal to or lower than the Maximum Applicable Rate shall
      be  accepted,  thus  requiring  such  Potential  Holder  to  purchase  the
      Outstanding shares of APS that are the subject of such Submitted Bid; and

            (C) the Submitted Bids of each Existing  Holder  specifying any rate
      per  annum  that is  higher  than the  Maximum  Applicable  Rate  shall be
      accepted and the Submitted  Sell Orders of each  Existing  Holder shall be
      accepted,  in both cases only in an amount equal to the difference between
      (1) the  number of  Outstanding  shares of APS then held by such  Existing
      Holder  subject to such  Submitted Bid or Submitted Sell Order and (2) the
      number of shares of APS obtained by multiplying (x) the difference between
      the Available APS and the aggregate  number of  Outstanding  shares of APS
      subject  to  Submitted  Bids  described  in  paragraph   10(e)(ii)(A)  and
      paragraph  10(e)(ii)(B)  by (y) a fraction the numerator of which shall be
      the  number  of  Outstanding  shares of APS held by such  Existing  Holder
      subject to such Submitted Bid or Submitted Sell Order and the  denominator
      of which shall be the number of  Outstanding  shares of APS subject to all
      such Submitted Bids and Submitted Sell Orders.

      (iii) If, as a result of the procedures described in paragraph 10(e)(i) or
paragraph 10(e)(ii),  any Existing Holder would be entitled or required to sell,
or any Potential Holder would be entitled or required to purchase, a fraction of
a share of APS on any Auction Date,  the Auction Agent shall,  in such manner as
in its sole discretion it shall determine, round up or down the number of shares
of APS to be  purchased or sold by any  Existing  Holder or Potential  Holder on
such Auction  Date so that each  Outstanding  share of APS  purchased or sold by
each Existing  Holder or Potential  Holder on such Auction Date shall be a whole
share of APS.

      (iv) If, as a result of the  procedures  described in paragraph  10(e)(i),
any Potential Holder would be entitled or required to purchase less than a whole
share of APS on any Auction Date, the Auction Agent shall,  in such manner as in
its sole  discretion  it shall  determine,  allocate  shares of APS for purchase
among  Potential  Holders so that only whole shares of APS are purchased on such
Auction Date by any Potential Holder,  even if such allocation results in one or
more of such Potential  Holders not purchasing any shares of APS on such Auction
Date.

      (v)  Based  on the  results  of each  Auction,  the  Auction  Agent  shall
determine, with respect to each Broker-Dealer that submitted Bids or Sell Orders
on behalf of Existing  Holders or Potential  Holders,  the  aggregate  number of
Outstanding  shares  of APS to be  purchased  and the  aggregate  number  of the
Outstanding  shares of APS to be sold by such  Potential  Holders  and  Existing
Holders and, to the extent that such aggregate  number of Outstanding  shares to
be purchased and such aggregate number of Outstanding  shares to be sold differ,


                                       27

the Auction Agent shall determine to which other Broker-Dealer or Broker-Dealers
acting for one or more  purchasers  such  Broker-Dealer  shall deliver,  or from
which other Broker-Dealer or Broker-Dealers  acting for one or more sellers such
Broker-Dealer shall receive, as the case may be, Outstanding shares of APS

      (f)  Miscellaneous.  The  Trust  may  interpret  the  provisions  of  this
paragraph 10 to resolve any inconsistency or ambiguity, remedy any formal defect
or make any other change or modification that does not  substantially  adversely
affect the rights of Beneficial Owners of APS. A Beneficial Owner or an Existing
Holder  (A) may  sell,  transfer  or  otherwise  dispose  of  shares of APS only
pursuant to a Bid or Sell Order in accordance  with the procedures  described in
this paragraph 10 or to or through a Broker-Dealer, provided that in the case of
all transfers other than pursuant to Auctions such Beneficial  Owner or Existing
Holder,  its  Broker-Dealer,  if  applicable,  or its Agent  Member  advises the
Auction  Agent of such  transfer  and (B) except as  otherwise  required by law,
shall  have the  ownership  of the shares of APS held by it  maintained  in book
entry form by the  Securities  Depository  in the  account of its Agent  Member,
which in turn  will  maintain  records  of such  Beneficial  Owner's  beneficial
ownership.  Neither  the Trust nor any  Affiliate  shall  submit an Order in any
Auction.  Any Beneficial Owner that is an Affiliate shall not sell,  transfer or
otherwise  dispose of shares of APS to any Person  other than the Trust.  All of
the  Outstanding  shares  of APS of a series  shall be  represented  by a single
certificate  registered in the name of the nominee of the Securities  Depository
unless otherwise required by law or unless there is no Securities Depository. If
there is no Securities Depository, at the Trust's option and upon its receipt of
such documents as it deems  appropriate,  any shares of APS may be registered in
the  Stock  Register  in the  name of the  Beneficial  Owner  thereof  and  such
Beneficial Owner thereupon will be entitled to receive 77 certificates  therefor
and required to deliver certificates therefor upon transfer or exchange thereof.

      11.  SECURITIES  DEPOSITORY;  STOCK  CERTIFICATES.   (a)  If  there  is  a
Securities  Depository,  one  certificate  for all of the  shares of APS of each
series shall be issued to the  Securities  Depository and registered in the name
of the  Securities  Depository or its nominee.  Additional  certificates  may be
issued as necessary to represent shares of APS. All such certificates shall bear
a legend  to the  effect  that  such  certificates  are  issued  subject  to the
provisions  restricting the transfer of shares of APS contained in these Amended
By-Laws.  Unless the Trust shall have elected,  during a Non-Payment  Period, to
waive this requirement,  the Trust will also issue stop-transfer instructions to
the Auction Agent for the shares of APS. Except as provided in paragraph

      (b) below,  the  Securities  Depository or its nominee will be the Holder,
and no Beneficial  Owner shall receive  certificates  representing its ownership
interest in such shares.  (b) If the Applicable Rate applicable to all shares of
APS of a series shall be the  Non-Payment  Period Rate or there is no Securities
Depository,  the Trust may at its option issue one or more new certificates with
respect to such  shares  (without  the legend  referred to in  paragraph  11(a))
registered in the names of the  Beneficial  Owners or their nominees and rescind
the  stop-transfer  instructions  referred to in paragraph 11(a) with respect to
such shares.
