     Registrant pursuant to Section 8(b) of the  Investment Company Act of 1940,
     as amended.  However, interests in the Registrant have  not been registered
     under the  Securities Act  of 1933,  as amended  (the "1933  Act"), because
     such  interests will  be issued  solely in  private  placement transactions
     that do  not involve any  "public offering" within  the meaning  of Section
     4(2) of the 1933  Act.  Investments in the  Registrant may be made  only by
     investment  companies,  common  or  commingled  trust   funds,  or  similar
     organizations  or  entities  that are  "accredited  investors"  within  the
     meaning of Regulation D  under the 1933 Act.   This Registration Statement,

                                       PART A 

              Responses  to Items 1 through 3  and 5A have been omitted pursuant
     to Paragraph 4 of Instruction F of the General Instructions to Form N-1A.
        
     Item 4.  General Description of Registrant
              National Limited  Maturity Municipals Portfolio (the  "Portfolio")
     is  a  diversified,  open-end  management  investment   company  which  was
     organized  as a trust  under the laws  of the State of  New York  on May 1,
     1992. Interests in  the Portfolio are  issued solely  in private  placement
     transactions that do not involve  any "public offering" within  the meaning
     of  Section 4(2)  of  the Securities  Act of  1933,  as amended  (the "1933
     Act"). Investments in  the Portfolio may be  made only by U.S.  and foreign
     investment  companies,  common  or  commingled  trust   funds,  or  similar
     organizations  or  entities  that are  "accredited  investors"  within  the
     meaning of  Regulation D under  the 1933 Act.  This Registration Statement,
     as amended, does  not constitute an offer  to sell, or the  solicitation of
     an offer to buy, any "security" within the meaning of the 1933 Act.
         
              The Portfolio's  investment  objective is  to provide  (1) a  high
     level  of current  income exempt  from regular  federal income tax  and (2)
     limited  principal  fluctuation.   The  Portfolio  seeks  to   achieve  its
     objective by  investing primarily  in municipal  obligations (as  described
     below) having a  dollar weighted average duration of between three and nine
     years and  which are  rated at  least investment  grade by  a major  rating
     agency or, if  unrated, are determined to  be of at least  investment grade
     quality  by  the  Portfolio's investment  adviser,  Boston  Management  and
     Research (the "Investment Adviser" or "BMR").

              Additional  information  about  the  investment  policies  of  the
     Portfolio  appears in  Part  B.  The Portfolio  is  not  intended to  be  a
     complete investment program,  and a  prospective investor should  take into
     account its  objectives and other investments when considering the purchase
     of interests in the Portfolio.  The Portfolio cannot assure  achievement of
     its investment objective.
        
     Investment Policies and Risks 
              The  Portfolio  seeks  to  achieve  its  investment  objective  by
     investing at least  80% of its net  assets during periods of  normal market
     conditions in  municipal obligations the  interest on which  is exempt from
     regular  federal income tax.  The foregoing  policy is a fundamental policy
     of  the Portfolio and  may not be  changed unless  authorized by a  vote of
     investors in the Portfolio.
         
        
              At  least 80%  of  the  Portfolio's net  assets will  normally  be
     invested in  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
     ("S&P")  or  Fitch  Investors  Service,  Inc.  ("Fitch")) or,  if  unrated,
     determined by the  Investment Adviser to  be of  at least investment  grade
     quality.  The Portfolio may invest up to 20% of its net assets in municipal

                                        A - 1
<PAGE>






     obligations  rated below investment grade (but not lower than B by Moody's,
     S&P  or  Fitch) and  unrated  municipal  obligations  considered  to be  of
     comparable quality by the Investment Adviser.   Municipal obligations rated
     Baa or BBB  may have speculative characteristics. Also, changes in economic
     conditions or  other circumstances  are more likely  to lead to  a weakened
     capacity  to  make principal  and  interest payments  than in  the  case of
     higher rated  obligations. Securities rated  below Baa or  BBB are commonly
     known as "junk bonds".  The Portfolio may retain an obligation whose rating
     drops  below  B after  its  acquisition  if  such  retention is  considered
     desirable by the Investment Adviser. See  "Additional Risk Considerations."
     For a  description of  municipal obligation  ratings, see  the Appendix  to
     Part B.
         
              In  pursuing  its investment  objective,  the  Portfolio  seeks to
     invest in a portfolio having a dollar  weighted average duration of between
     three  and  nine years.  Duration  represents the  dollar  weighted average
     maturity of expected  cash flows (i.e., interest and principal payments) on
     one  or more  debt  obligations, discounted  to  their present  values. The
     duration of an obligation is usually not more than its stated maturity  and
     is  related  to the  degree  of  volatility  in  the market  value  of  the
     obligation.  Maturity measures  only the  time until  a bond or  other debt
     security  provides its  final payment;  it does  not take  into account the
     pattern of  a security's payments  over time. Duration  takes both interest
     and principal payments  into account and, thus, in the Investment Adviser's
     opinion, is a  more accurate measure  of a debt  security's sensitivity  to
     changes in interest rates. In computing the  duration of its portfolio, the
     Portfolio  will have to estimate the  duration of debt obligations that are
     subject to prepayment or redemption by the issuer, based on projected  cash
     flows from such obligations.

              The Portfolio may  use various techniques  to shorten  or lengthen
     the dollar  weighted  average  duration  of its  portfolio,  including  the
     acquisition of debt  obligations at a premium or discount, and transactions
     in futures contracts  and options on  futures. Subject  to the  requirement
     that the  dollar weighted average  portfolio duration will  not exceed nine
     years,  the Portfolio  may  invest in  individual  debt obligations  of any
     maturity.
        
              Municipal  Obligations.    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 bond  counsel, exempt from regular  federal income tax.   Public purpose
     municipal  bonds  include  general  obligation  bonds  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.     Municipal  notes   include  bond   anticipation  notes,   tax
     anticipation notes 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.

              Distributions  to  corporate  investors  of  interest income  from
     certain types  of  municipal obligations  may  be  subject to  the  federal
     alternative minimum tax (the "AMT").  As  at March 31, 1996, the  Portfolio
     had 20.5% of  its net assets invested  in such obligations.   The Portfolio
     may not be suitable for investors subject to the AMT.
         
        
              Concentration.   The  Portfolio  may  invest 25%  or more  of  its
     assets in municipal obligations  of issuers located in the same state or in
     municipal  obligations of the same type, including, without limitation, the
     following:  general obligations  of  states  and localities;  lease  rental
     obligations of state  and local authorities; 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 Portfolio more  susceptible to adverse economic,  political or
     regulatory  occurrences affecting  a  particular  category of  issuer.  For
     example,   health   care-related  issuers   are  susceptible   to  medicaid
     reimbursement policies,  and national  and state  health care  legislation.
     As  the Portfolio's  concentration  increases, so  does  the potential  for
     fluctuation of the net asset value of an interest in the Portfolio.
         
              Diversified  Status.   The  Portfolio's  classification  under the
     Investment Company  Act  of  1940  (the  "1940  Act")  as  a  "diversified"
     investment company means that  with respect to 75% of its total  assets (1)
     the Portfolio  may not  invest more  than 5%  of its  total  assets in  the
     securities of any one issuer  (except U.S. Government obligations)  and (2)
     the  Portfolio  may  not  own  more  than  10%  of  the  outstanding voting
     securities of  any  one issuer.    Because  municipal obligations  are  not
     voting  securities,  there is  no  limit  on  the percentage  of  a  single
     issuer's obligations  which the Portfolio  may own so  long as it does  not
     invest more than 5% of  its total assets in the securities of  that issuer.
        
     Other Investment Practices
              The Portfolio  may engage  in the following  investment practices,
     some  of  which  may  be  considered  to  involve "derivative"  instruments
     because  they  derive  their value  from  another  instrument,  security or
     index.  In  addition, the Portfolio may temporarily borrow  up to 5% of the
     value of  its  total  assets  to  satisfy  redemption  requests  or  settle
     securities transactions.
          
              When-Issued Securities.  The  Portfolio 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 Portfolio agreed to pay
     for  them.  The Portfolio  may  also  purchase  instruments  that give  the
     Portfolio  the  option to  purchase  a  municipal  obligation  when and  if
     issued.

              Futures  Transactions.    The  Portfolio  may  purchase  and  sell
     various kinds of financial futures  contracts and options thereon  to hedge
     against  changes in  interest rates.   Futures  contracts may  be  based on
     various debt securities (such  as U.S. Government securities and  municipal
     obligations)  and securities  indices  (such as  the  Municipal Bond  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  Portfolio's  initial investment  in  these
     contracts.   The Portfolio may  not purchase or  sell futures contracts  or
     related  options,  except for  closing  purchase or  sale  transactions, if
     immediately  thereafter  the sum  of  the  amount  of  margin deposits  and
     premiums paid on the Portfolio's  outstanding positions would exceed  5% of
     the  market  value of  the  Portfolio's  net  assets.   These  transactions
     involve transaction  costs.  There can be no  assurance that the Investment
     Adviser's use of futures will be advantageous to the Portfolio.
         
        
              Insured Obligations.   The Portfolio 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  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  does   not  guarantee  the  market  value  of  the  insured
     obligations or the net asset value of the Portfolio's interests.
         
        
     Additional Risk Considerations
              Many  municipal obligations  offering high  current income  are in
     the lowest investment grade category (Baa or BBB),  lower categories or may
     be  unrated.   As indicated  above, the  Portfolio may  invest in municipal
     obligations  rated below investment grade (but not lower than B by Moody's,
     S&P or  Fitch) and comparable  unrated obligations.   The lowest investment
     grade, lower  rated and  comparable unrated municipal  obligations in which
     the Portfolio may  invest 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.
     Lower rated and  comparable unrated  municipal obligations  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 greater price
     volatility  due  to  such factors  as  interest  rate  sensitivity,  market
     perception  of  the  creditworthiness  of  the issuer  and  general  market
     liquidity (market risk).   Lower rated or unrated municipal obligations are
     also  more likely  to  react to  real  or perceived  developments affecting
     market and credit risk than are more  highly rated obligations, which react
     primarily  to  movements  in the  general  level  of interest  rates.   The
     Investment Adviser  seeks  to minimize  the  risks  of investing  in  below
     investment grade securities  through professional  investment analysis  and
     attention  to   current  developments  in   interest  rates  and   economic

                                        A - 4
<PAGE>






     conditions.   When  the  Portfolio  invests  in  lower  rated  and  unrated
     municipal  obligations, the  achievement of the  Portfolio's goals  is more
     dependent on the  Investment Adviser's ability  than would be  the case  if
     the Portfolio were  investing in municipal obligations in the higher rating
     categories.
         
        
              The Portfolio  may retain  defaulted obligations in  its portfolio
     when such retention is considered desirable by  the Investment Adviser.  In
     the case  of a  defaulted obligation,  the Portfolio  may incur  additional
     expense seeking recovery  of its investment.  Municipal obligations held by
     the Portfolio that are rated  below investment grade, but  that, subsequent
     to the assignment  of such rating, are backed by escrow accounts containing
     U.S. Government obligations,  may be  determined by the  Investment Adviser
     to  be  of  investment  grade  quality  for  purposes  of  the  Portfolio's
     investment policies.    The  Portfolio  may  retain  in  its  portfolio  an
     obligation whose  rating  drops below  B  after  its acquisition,  if  such
     retention  is considered  desirable by  the  Investment Adviser;  provided,
     however, that holdings  of obligations rated below Baa  or BBB will be less
     than 35% of net  assets.  In the event the rating  of an obligation held by
     the  Portfolio  is  downgraded,  causing  the   Portfolio  to  exceed  this
     limitation, the Investment  Adviser will (in  an orderly  fashion within  a
     reasonable period  of  time)  dispose  of  such  obligations  as  it  deems
     necessary  in  order  to   comply  with  the  Portfolio's   credit  quality
     limitations.  
         
        
              The  net asset value  of the Portfolio's interests  will change in
     response to  fluctuations in prevailing  interest rates and  changes in the
     value  of  the securities  held  by the  Portfolio.    When interest  rates
     decline, the value  of securities held by the  Portfolio can be expected to
     rise.  Conversely,  when interest rates rise,  the value of most  portfolio
     security holdings  can  be expected  to  decline.   Because  the  Portfolio
     intends to  limit  its average  portfolio  duration to  no more  than  nine
     years, its net asset value can be  expected to be less sensitive to changes
     in interest  rates than  that of  a fund  with a  longer average  portfolio
     duration.   Changes  in the  credit  quality of  the  issuers of  municipal
     obligations  held by the Portfolio will  affect the principal value of (and
     possibly the income  earned on) such obligations.   In addition, the values
     of such securities are affected  by changes in general  economic conditions
     and  business  conditions  affecting  the  specific   industries  of  their
     issuers.   Changes  by recognized  rating services  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 Portfolio'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.  An  investment in the
     Portfolio will not constitute a complete investment program.
         
        
              At times, a  substantial portion of the Portfolio's assets  may be
     invested in  securities as to  which the Portfolio,  by itself  or together

                                        A - 5
<PAGE>






     with other accounts managed by  the Investment 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 Portfolio  could find it  more difficult  to
     sell such securities when the  Investment 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 Portfolio's net asset value.
         
        
              The secondary  market for  some municipal  obligations  (including
     issues that  are privately placed with  the Portfolio) is  less liquid than
     that for taxable  debt obligations or  other more  widely traded  municipal
     obligations.  The Portfolio will not invest  in illiquid securities if more
     than 15% of  its net assets  would be invested  in securities that are  not
     readily marketable.   No established resale  market exists  for certain  of
     the  municipal obligations in which  the Portfolio 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
     Portfolio 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.
         
              Certain securities held by the Portfolio may permit the issuer  at
     its option  to "call", or  redeem, its  securities.  If  an issuer  were to
     redeem securities  held  by  the  Portfolio  during  a  time  of  declining
     interest rates, the  Portfolio may not be able  to reinvest the proceeds in
     securities  providing  the   same  investment  return  as   the  securities
     redeemed.  
        
              Some of the securities in which the Portfolio 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 Portfolio
     is required  to accrue  income from zero-coupon  bonds on a  current basis,
     even though it  does not receive that income currently  in cash.  Thus, the
     Portfolio may have to sell other investments to obtain cash needed to  make
     income distributions.
         
        
              The Portfolio  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.

              The   Portfolio  has   adopted   certain   fundamental  investment
              restrictions that are  enumerated in detail in Part B and that may
              not be changed unless authorized  by an investor vote.  Except for
              such enumerated  restrictions and  as otherwise indicated  in this
              Part A,  the investment  objective and policies  of the  Portfolio
              are not  fundamental policies  and accordingly  may be changed  by
              the Trustees  of the Portfolio  without obtaining  the approval of
              the investors in the  Portfolio.  If any changes were made  in the
              Portfolio's  investment  objective, the  Portfolio  might  have an
              investment  objective   different  from  the  objective   that  an
              investor considered  appropriate at  the time the  investor became
              an interest holder in the Portfolio. 
         
     Item 5.  Management of the Portfolio
              The Portfolio is organized as a trust under the  laws of the State
     of New York.  The Portfolio intends  to comply with all  applicable federal
     and state securities laws.

              Investment  Adviser.   The Portfolio  engages BMR,  a wholly-owned
     subsidiary of  Eaton Vance  Management ("Eaton  Vance"), as its  investment
     adviser.  Eaton Vance,  its affiliates  and its  predecessor companies have
     been  managing  assets  of  individuals  and  institutions since  1924  and
     managing investment companies since 1931.
        
              Acting under the  general supervision of the Board of  Trustees of
     the Portfolio,  BMR manages the  Portfolio's investments and  affairs.  BMR
     also furnishes for the use of the Portfolio office space and all  necessary
     office facilities,  equipment and personnel  for servicing the  investments
     of  the  Portfolio.   Under  its  investment  advisory  agreement with  the
     Portfolio, BMR receives a monthly advisory fee equal to the aggregate of:
         
              (a) a daily asset-based fee computed by applying the annual  asset
                    rate  applicable  to  that portion  of  the total  daily net
                    assets in each Category as indicated below, plus

              (b)  a  daily income-based  fee  computed  by applying  the  daily
                    income rate  applicable to  that portion of the  total daily
                    gross income (which portion shall bear the same relationship
                    to the total daily gross income on such day as that  portion
                    of the  total daily net assets in the same Category bears to
                    the total daily net assets  on such day) in each Category as
                    indicated below:

                                                                 Annual  Daily
                                                                 Asset   Income

     6                $3 billion and over                        0.175%  1.75%
        
              As   at  March  31,   1996,  the  Portfolio  had   net  assets  of
     $134,776,368. For the fiscal year ended March  31, 1996, the Portfolio paid
     BMR advisory fees equivalent to 0.47% of the Portfolio's  average daily net
     assets for such year. 
         
        
              BMR or  Eaton  Vance  acts as  investment  adviser  to  investment
     companies  and various  individual and  institutional  clients with  assets
     under  management  of over  $16  billion.  Eaton  Vance  is a  wholly-owned
     subsidiary  of Eaton  Vance Corp.,  a publicly-held  holding company  that,
     through its  subsidiaries and affiliates,  engages primarily in  investment
     management, administration and marketing activities. 
         
        
              Raymond  E. Hender  has  acted  as the  portfolio manager  of  the
     Portfolio since the  Portfolio commenced operations.  He joined Eaton Vance
     and BMR as a Vice President in 1992.  Prior to  joining Eaton Vance, he was
     a Senior Vice President of Bank of New  England (1989-1992) and a Portfolio
     Manager at Fidelity Management & Research Company (1977-1988). 
         
        
              Municipal obligations are normally traded on a net basis  (without
     commission) through broker-dealers and  banks acting for their own account.
     Such firms attempt  to profit from such  transactions by buying at  the bid
     price  and selling  at  the  higher asked  price  of  the market,  and  the
     difference is customarily  referred to as  the spread.  In selecting  firms
     which will  execute portfolio transactions,  BMR judges their  professional
     ability  and  quality  of  service and  uses  its  best  efforts  to obtain
     execution at  prices  which  are  advantageous  to  the  Portfolio  and  at
     reasonably competitive spreads. Subject to the foregoing, BMR may  consider
     sales of shares of  investment companies sponsored by BMR or Eaton Vance as
     a factor in the selection of firms to execute portfolio transactions.   The
     Portfolio  and  BMR have  adopted  Codes  of  Ethics  relating to  personal
     securities transactions.   The Codes permit Eaton Vance personnel to invest
     in securities  (including securities that may  be purchased or held  by the
     Portfolio)  for  their  own accounts,  subject  to  certain  pre-clearance,
     reporting and other restrictions and procedures contained in such Codes.
         
        
              The Portfolio is  responsible for the payment of  all of its costs
     and  expenses  not  expressly  stated  to  be  payable  by  BMR  under  the
     investment advisory agreement.
         
     Item 6.  Capital Stock and Other Securities
              The Portfolio is organized as  a trust under the laws of the State
     of New York  and intends  to be treated  as a partnership  for federal  tax
     purposes. Under  the Declaration of  Trust, the Trustees  are authorized to
     issue interests in  the Portfolio. Each investor  is entitled to a  vote in
     proportion to  the amount of  its investment in  the Portfolio. Investments
     in the Portfolio  may not be transferred, but  an investor may withdraw all

                                        A - 8
<PAGE>






     or any portion of its investment  at any time at net asset value. Investors
     in the Portfolio will each be liable for  all obligations of the Portfolio.
     However, the risk of an  investor in the Portfolio incurring financial loss
     on account  of such  liability is  limited to circumstances  in which  both
     inadequate insurance exists and the Portfolio itself is unable  to meet its
     obligations.

              The  Declaration  of  Trust   provides  that  the  Portfolio  will
     terminate 120  days after the  complete withdrawal of  any investor in  the
     Portfolio unless either  the remaining investors,  by unanimous  vote at  a
     meeting of such investors, or a majority of  the Trustees of the Portfolio,
     by  written instrument consented to by all investors, agree to continue the
     business of the  Portfolio. This provision is consistent with the treatment
     of the Portfolio as a partnership for federal income tax purposes.

              Investments  in the  Portfolio  have no  preemptive  or conversion
     rights  and are fully  paid and  nonassessable by the  Portfolio, except as
     set  forth  above.  The  Portfolio  is  not  required  and  has  no current
     intention to hold annual  meetings of investors, but the Portfolio may hold
     special meetings of  investors when in the  judgment of the Trustees  it is
     necessary or desirable to submit  matters for an investor vote. Changes  in
     fundamental  policies or  restrictions will  be submitted  to investors for
     approval.  The  investment  objective  and  all  nonfundamental  investment
     policies of the Portfolio may be changed  by the Trustees of the  Portfolio
     without  obtaining  the  approval   of  the  investors  in  the  Portfolio.
     Investors  have under  certain circumstances  (e.g.,  upon application  and
     submission of  certain specified documents  to the Trustees  by a specified
     number  of investors)  the  right to  communicate  with other  investors in
     connection with  requesting  a meeting  of  investors  for the  purpose  of
     removing  one  or  more  Trustees.  Any  Trustee  may  be  removed  by  the
     affirmative  vote  of  holders  of  two-thirds  of  the  interests  in  the
     Portfolio.
        
              Information  regarding pooled  investment  entities or  funds that
     invest  in  the  Portfolio  may  be  obtained  by  contacting  Eaton  Vance
     Distributors, Inc.,  24 Federal  Street, Boston, MA  02110, (617) 482-8260.
     Smaller  investors  in the  Portfolio  may  be  adversely  affected by  the
     actions of  a larger investor in  the Portfolio.   For example, if  a large
     investor  withdraws  from  the  Portfolio,  the   remaining  investors  may
     experience  higher pro  rata operating  expenses,  thereby producing  lower
     returns.  Additionally, the Portfolio may hold fewer securities,  resulting
     in increased  portfolio risk, and experience decreasing economies of scale.
     However, this possibility exists  as well for historically structured funds
     that have large or institutional investors.
         
        
              As  of  July  1,  1996,  EV  Marathon  National  Limited  Maturity
     Municipals Fund, a series of  Eaton Vance Investment Trust,  controlled the
     Portfolio  by  virtue  of owning  approximately  83.1%  of the  outstanding
     voting interests in the Portfolio.
         
              The  net asset value  of the  Portfolio is determined each  day on

                                        A - 9
<PAGE>






     which the New  York Stock  Exchange (the  "Exchange") is  open for  trading
     ("Portfolio  Business Day").  This  determination  is made  each  Portfolio
     Business Day as of  the close of regular trading on the Exchange (currently
     4:00 p.m., New York time) (the "Portfolio Valuation Time").

              Each  investor  in  the  Portfolio  may  add  to  or  reduce   its
     investment  in the  Portfolio  on each  Portfolio  Business Day  as of  the
     Portfolio Valuation  Time. The  value of  each investor's  interest in  the
     Portfolio will  be determined  by multiplying  the net asset  value of  the
     Portfolio  by the percentage,  determined on  the prior  Portfolio Business
     Day, which  represents that investor's  share of the  aggregate interest in
     the  Portfolio on  such prior  day.  Any additions  or withdrawals  for the
     current  Portfolio  Business Day  will  then be  recorded.  Each investor's
     percentage of  the  aggregate  interest  in  the  Portfolio  will  then  be
     recomputed as a percentage equal to a  fraction (i) the numerator of  which
     is the  value of  such investor's  investment in  the Portfolio  as of  the
     Portfolio Valuation  Time  on the  prior  Portfolio  Business Day  plus  or
     minus, as the  case may be, the  amount of any additions  to or withdrawals
     from the  investor's investment in  the Portfolio on  the current Portfolio
     Business Day and (ii)  the denominator of which is the aggregate  net asset
     value of the  Portfolio as  of the Portfolio  Valuation Time  on the  prior
     Portfolio Business Day plus  or minus, as  the case may  be, the amount  of
     the net additions to  or withdrawals from  the aggregate investment in  the
     Portfolio  on the current  Portfolio Business Day  by all  investors in the
     Portfolio. The percentage so determined  will then be applied  to determine
     the  value of  the investor's  interest in  the Portfolio  for the  current
     Portfolio Business Day.
        
              The  Portfolio will allocate at least annually among its investors
     each investor's distributive  share of the Portfolio's net taxable (if any)
     and  tax-exempt  investment income,  net  realized capital  gains,  and any
     other items of  income, gain, loss,  deduction or  credit. The  Portfolio's
     net investment income  consists of all  income accrued  on the  Portfolio's
     assets, less all actual and  accrued expenses of the  Portfolio, determined
     in accordance with generally accepted accounting principles.
         
        
              Under the  anticipated method  of operation of the  Portfolio, the
     Portfolio will  not be subject  to any  federal income tax.   (See  Part B,
     Item 20.)   However, each investor in the  Portfolio will take into account
     its allocable share of  the Portfolio's ordinary income and capital gain in
     determining its  federal income tax  liability. The  determination of  each
     such  share will  be made in  accordance with the  governing instruments of
     the  Portfolio,  which   instruments  are  intended  to  comply   with  the
     requirements of the Code and the regulations promulgated thereunder.
         
        
              It  is intended  that the  Portfolio's assets  and income  will be
     managed  in such  a way  that an  investor in  the Portfolio  that seeks to
     qualify as a  regulated investment company under  the Code will be  able to
     satisfy the requirements for such qualification.

     Item 7.  Purchase of Interests in the Portfolio
              Interests  in the Portfolio are issued solely in private placement
     transactions that do not involve  any "public offering" within  the meaning
     of Section  4(2) of the 1933  Act. See "General Description  of Registrant"
     above.
        
              An investment in the Portfolio will be made without a sales  load.
     All investments received by  the Portfolio will be effected as of  the next
     Portfolio  Valuation  Time.  The  net  asset  value  of  the  Portfolio  is
     determined at the  Portfolio Valuation Time on each Portfolio Business Day.
     The Portfolio will be  closed for business and will not price  interests in
     the  Portfolio  on  the  following  business   holidays:  New  Year's  Day,
     Presidents'  Day, Good  Friday, Memorial Day,  Independence Day, Labor Day,
     Thanksgiving Day  and Christmas  Day. The  Portfolio's net  asset value  is
     computed  in accordance  with  procedures  established by  the  Portfolio's
     Trustees.
         
        
              The Portfolio's net asset value is determined by Investors Bank  &
     Trust Company  (as custodian and agent  for the Portfolio) based  on market
     or fair value  in the manner authorized  by the Trustees of  the Portfolio.
     The  net asset  value  is computed  by subtracting  the liabilities  of the
     Portfolio from the value  of its total assets.   Municipal obligations will
     normally  be  valued on  the  basis of  valuations  furnished by  a pricing
     service.     For  further  information  regarding   the  valuation  of  the
     Portfolio's assets, see Part B, Item 19.
         
              There  is  no minimum  initial  or  subsequent investment  in  the
     Portfolio. The Portfolio  reserves the right to cease accepting investments
     at any time or to reject any investment order.

              The   placement   agent  for   the   Portfolio   is   Eaton  Vance
     Distributors, Inc. ("EVD").  The principal business  address of  EVD is  24
     Federal Street, Boston,  Massachusetts 02110. EVD receives  no compensation
     for serving as the placement agent for the Portfolio.
        
     Item 8.  Redemption or Decrease of Interest
              An investor in the Portfolio  may withdraw all of (redeem)  or any
     portion  of  (decrease) its  interest  in  the  Portfolio  if a  withdrawal
     request in proper  form is furnished by the  investor to the Portfolio. All
     withdrawals  will be effected as of the  next Portfolio Valuation Time. The
     proceeds of a  withdrawal will  be paid by  the Portfolio  normally on  the
     Portfolio Business Day the withdrawal is effected, but  in any event within
     seven days.  The Portfolio  reserves the  right to  pay the  proceeds of  a
     withdrawal  (whether a redemption or decrease) by a distribution in kind of
     portfolio  securities (instead  of  cash).  The securities  so  distributed
     would be  valued at the same amount as that assigned to them in calculating
     the net  asset value for the  interest (whether complete or  partial) being
     withdrawn.  If  an investor  received  a  distribution  in  kind upon  such
     withdrawal,  the  investor  could  incur  brokerage  and other  charges  in
     converting  the  securities to  cash.  The  Portfolio  has  filed with  the
     Securities and  Exchange Commission a  notification of election  on Form N-

                                        A - 11
<PAGE>






     18F-1  committing  to pay  in  cash  all requests  for  withdrawals  by any
     investor,  limited in amount  with respect to  such investor  during any 90
     day  period to the lesser of (a) $250,000 or  (b) 1% of the net asset value
     of the Portfolio at the beginning of such period.
         
              Investments in the Portfolio may not be transferred.

              The right of any investor  to receive payment with respect to  any
     withdrawal  may be  suspended  or the  payment  of the  withdrawal proceeds
     postponed  during any  period in which  the Exchange is  closed (other than
     weekends or holidays) or  trading on the Exchange is restricted or,  to the
     extent otherwise permitted  by the  1940 Act,  if an  emergency exists,  or
     during  any  other period  permitted  by order  of  the Commission  for the
     protection of investors.

     Item 12.  General Information and History.
              Effective December 8, 1995, the Portfolio's name was changed  from
     "National  Limited  Maturity  Tax  Free  Portfolio"  to  "National  Limited
     Maturity Municipals Portfolio."
         
        
     Item 13.  Investment Objectives and Policies.
              Part  A  contains  additional  information  about  the  investment
     objective and  policies of National  Limited Maturity Municipals  Portfolio
     (the "Portfolio"). This Part  B should be read in conjunction with  Part A.
     Capitalized terms used  in this Part B  and not otherwise defined  have the
     meanings given them in Part A.
         
        
     Municipal Obligations
              Municipal  obligations  are issued  to  obtain  funds  for various
     public  and private purposes.   Such  obligations include 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.   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 federal alternative minimum
     tax:  (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. In  assessing the federal income tax treatment of interest

     on any  municipal  obligation, the  Portfolio  will  generally rely  on  an
     opinion of the  issuer's counsel (when  available) and  will not  undertake
     any  independent  verification  of the  basis  for the  opinion.    The two
     principal  classifications  of  municipal  bonds  are  "general obligation"
     bonds and "revenue" bonds.
         
              Interest on  certain "private activity bonds"  issued after August
     7, 1986  is exempt from  regular federal income  tax, but such interest  is
     treated  as a tax  preference item that could  subject the  recipient to or
     increase  the recipient's  liability for  the  federal alternative  minimum
     tax.   It  should be  noted  that, for  a  corporate holder  (other than  a
     regulated investment company)  of an interest in the Portfolio, interest on
     all  municipal  obligations  (whenever issued)  is  included  in  "adjusted
     current earnings"  for purposes of  the federal alternative  minimum tax as
     applied to corporations  (to the extent not already included in alternative
     minimum taxable income as income attributable to private activity bonds).
        
              Any recognized gain or  income attributable to market  discount on
     long-term tax-exempt municipal  obligations (i.e., obligations with  a term
     of  more than  one year)  purchased after  April  30, 1993  other than,  in
     general, at their original issue, is taxable  as ordinary income.  A  long-
     term debt 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.
         
              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.

              The principal  security for a  revenue bond is  generally 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 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  Portfolio 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  Portfolio
     anticipates that  it  would, under  normal  circumstances, dispose  of  any
     equity securities so acquired within a reasonable period of time.

              While  most municipal  bonds pay  a fixed  rate of  interest semi-
     annually in cash,  there are  exceptions. Some bonds  pay no periodic  cash
     interest, but  rather make a  single payment at  maturity representing both
     principal and  interest. Bonds may  be issued or  subsequently offered with
     interest coupons  materially greater  or less than  those then  prevailing,
     with price adjustments reflecting such deviation.

              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 Portfolio  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 Investment Adviser)  to evaluate or
     protect  any real  estate,  facilities or  other  assets securing  any such
     obligation or acquired by the Portfolio as a result of  any such event, and
     the  Portfolio may  also  manage (or  engage  other persons  to  manage) or
     otherwise deal  with  any  real  estate,  facilities  or  other  assets  so
     acquired.  The  Portfolio  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  Portfolio. The Portfolio will incur  additional expenditures in taking

                                        B - 3
<PAGE>






     protective action  with respect  to  portfolio obligations  in default  and
     assets securing such obligations.
        
              The  yields  on  municipal  obligations  will  be  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
     that  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 such  obligations will normally fluctuate  with changes
     in interest rates, and therefore the net asset value of the Portfolio  will
     be affected by such changes.
         
     Risks of Concentration
        
              Obligations of  Particular Types  of Issuers.   The  Portfolio may
     invest 25% or more of its total assets in municipal obligations of  issuers
     located in  the same state  or in municipal  obligations of the same  type.
     There could  be economic, business  or political  developments which  might
     affect  all  municipal  obligations   of  the  same  type.  In  particular,
     investments in industrial revenue bonds 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.
        
         
        
              Life care facilities are an alternative form of long-term  housing
     for the elderly  which offer residents  the independence  of a  condominium

                                        B - 4
<PAGE>






     life  style  and,  if  needed,  the  comprehensive  care  of  nursing  home
     services. Bonds to  finance these facilities  have been  issued by  various
     state and  local authorities. Because  the bonds 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,  because 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 Portfolio  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  are issued  by a state  or local  government 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.  A trustee  is usually
     responsible for administering the terms of the  participation and enforcing
     the participants' rights  in the  underlying lease. Leases  and installment
     purchase  or conditional sale contracts  (which normally  provide for title
     to the leased assets  to pass eventually  to the governmental issuer)  have
     evolved  as  a means  for  governmental  issuers  to  acquire property  and
     equipment  without meeting  the constitutional  and statutory  requirements
     for the issuance of debt. State debt-issuance  limitations are deemed to be
     inapplicable to these  arrangements because of the inclusion in many leases
     or  contracts  of   "non-appropriation"  clauses  that  provide   that  the
     governmental issuer has  no obligation to  make future  payments under  the
     lease  or contract  unless money is  appropriated for  such purpose  by the
     appropriate legislative  body on  a yearly  or other  periodic basis.  Such
     arrangements  are, therefore,  subject to  the risk  that  the governmental
     issuer will not appropriate funds for lease payments. 
         
        
              Certain  municipal lease obligations owned by the Portfolio may be
     deemed  illiquid  for  purposes  of  the   Portfolio's  15%  limitation  on
     investments in  illiquid securities,  unless determined  by the  Investment
     Adviser,  pursuant to  guidelines  adopted by  the  Trustees, to  be liquid
     securities  for purposes of such  limitation. In  determining the liquidity
     of  municipal lease  obligations, the  Investment Adviser  will  consider a

                                        B - 5
<PAGE>






     variety of  factors including: (1)  the willingness  of dealers to  bid for
     the security;  (2) the number  of dealers willing  to purchase or sell  the
     obligation and  the number of other potential buyers;  (3) the frequency of
     trades  and  quotes  for  the  obligation;  and   (4)  the  nature  of  the
     marketplace  trades. In  addition,  the  Investment Adviser  will  consider
     factors unique to particular lease obligations  affecting the marketability
     thereof. These  include the general  creditworthiness of the  municipality,
     the importance of  the property covered by  the lease to  the municipality,
     and  the  likelihood that  the  marketability  of  the  obligation will  be
     maintained throughout the time the obligation is held  by the Portfolio. In
     the  event the  Portfolio acquires an  unrated municipal  lease obligation,
     the  Investment Adviser  will  be responsible  for  determining the  credit
     quality of such  obligation on an ongoing basis, including an assessment of
     the likelihood that the lease may or may not be canceled.
         
     Zero Coupon Bonds
              Zero  coupon bonds are  debt obligations which do  not require the
     periodic payment  of interest and are issued at a significant discount from
     face value.  The discount  approximates the  total amount  of interest  the
     bonds will accrue and compound over the period until maturity  at a rate of
     interest  reflecting  the  market rate  of  the  security  at the  time  of
     issuance. Zero  coupon bonds benefit the issuer  by mitigating its need for
     cash to meet  debt service,  but also require  a higher  rate of return  to
     attract investors who are willing to defer receipt of such cash.

     Insurance
              Insured municipal obligations held by the  Portfolio (if any) will
     be insured as  to their scheduled  payment of principal and  interest under
     either (i) an  insurance policy obtained  by the  issuer or underwriter  of
     the obligation at  the time of its  original issuance or (ii)  an insurance
     policy  obtained by  the  Portfolio  or a  third  party subsequent  to  the
     obligation's  original  issuance  (which  may  not  be  reflected  in   the
     obligation's  market value).  In either  event  such insurance  may provide
     that  in the event  of nonpayment  of interest  or principal when  due with
     respect to an insured obligation, the insurer is  not required to make such
     payment until  a specified time  has lapsed (which may  be 30 days  or more
     after notice).

     Credit Quality
              The Portfolio  is dependent on the  Investment Adviser's judgment,
     analysis   and  experience   in  evaluating   the   quality  of   municipal
     obligations. In evaluating the credit  quality of a particular  issue, when
     rated   or  unrated,  the  Investment  Adviser   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  issuer, the
     ability of the  issuer's management and regulatory matters.  The Investment
     Adviser  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

                                        B - 6
<PAGE>






     financial markets.
        
              See  "Portfolio  of  Investments"  in  the "Financial  Statements"
     incorporated by  reference into this Part  B with respect to  any defaulted
     obligations held by the Portfolio.
         
        
     Short-Term Trading
              The  Portfolio  may  sell   (and  later  purchase)  securities  in
     anticipation  of a  market decline (a  rise in interest  rates) or purchase
     (and later sell) securities in anticipation of a  market rise (a decline in
     interest  rates). In addition, a security may be sold and another purchased
     at approximately  the same time  to take  advantage of  what the  Portfolio
     believes  to be  a  temporary disparity  in  the normal  yield relationship
     between the two  securities. Yield disparities  may occur  for reasons  not
     directly related  to the  investment quality  of particular  issues or  the
     general movement of  interest rates, such as changes  in the overall demand
     for or supply of various types of  municipal obligations or changes in  the
     investment  objectives  of  investors.  Such  trading  may  be expected  to
     increase the portfolio  turnover rate, which may increase capital gains and
     the  expenses  incurred in  connection  with  such trading.  The  Portfolio
     anticipates  that  its annual  portfolio turnover  rate will  generally not
     exceed 100% (excluding turnover of  securities having maturity of  one year
     or  less).  A  100% annual turnover  rate would occur,  for example, if all
     the securities held by the Portfolio were replaced once  in a period of one
     year.   A high turnover  rate (100% or  more) necessarily involves  greater
     expenses to  the Portfolio.   The  Portfolio engages  in portfolio  trading
     (including  short-term trading) if it believes that a transaction including
     all  costs  will  help  in   achieving  its  investment  objective.     The
     Portfolio's portfolio turnover rates for  the fiscal years ended  March 31,
     1996 and 1995, were 68% and 56%, respectively.
         
     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 Portfolio's  commitment and are  subject to certain  conditions such as
     the issuance  of  satisfactory  legal  opinions.  The  Portfolio  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  Portfolio to buy  such securities on a  settlement date  that could be
     several months or several years in the future.

              The  Portfolio  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 Portfolio  enters into  the purchase  commitment. The  Portfolio's
     custodian will segregate  cash or high  grade liquid  debt securities in  a
     separate  account of the Portfolio in an amount at least equal to the when-

                                        B - 7
<PAGE>






     issued commitments. If the  value of the securities placed  in the separate
     account declines,  additional cash  or high  grade  liquid debt  securities
     will be  placed in the account  on a daily basis  so that the  value of the
     account  will at  least  equal the  amount  of the  Portfolio's when-issued
     commitments.  When the Portfolio 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 Portfolio 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  Portfolio 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 Portfolio's  net
     asset value  than  if it  solely  set aside  cash  to pay  for  when-issued
     securities.

     Floating or Variable Rate Obligations
              The Portfolio may purchase  floating or variable rate obligations.
     Floating  or  variable  rate instruments  provide  for  adjustments  in the
     interest  rate  at  specified  intervals (weekly,  monthly,  semi-annually,
     etc.). The revised  rates are  usually set at  the issuer's discretion,  in
     which case  the investor normally  enjoys the  right to "put"  the security
     back to the  issuer or the issuer's agent. Rate revisions may alternatively
     be determined by formula or  in some other contractual fashion. Floating or
     variable  rate obligations  normally  provide that  the  holder can  demand
     payment of the obligation  on short notice at par with accrued interest and
     are  frequently  secured by  letters  of  credit  or  other credit  support
     arrangements provided by banks. To  the extent that such letters  of credit
     or  other  arrangements  constitute  an  unconditional   guarantee  of  the
     issuer's obligations, a bank  may be  treated as the  issuer of a  security
     for  the purpose  of  complying with  the diversification  requirements set
     forth in Section  5(b) of  the Investment Company  Act of  1940 (the  "1940
     Act") and Rule  5b-2 thereunder. The Portfolio would anticipate using these
     obligations  as cash  equivalents  pending longer  term  investment of  its
     funds.

     Redemption, Demand and Put Features
              Most municipal  bonds have a  fixed final  maturity date. However,
     it is  commonplace for  the issuer to  reserve the right  to call  the bond
     earlier. 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 (protecting  to some  degree against  a
     rise  in   interest  rates)  while   providing  greater  opportunity   than
     comparable intermediate  term bonds, because the  Portfolio may  retain the
     bond if interest  rates decline. By  acquiring these  kinds of  obligations
     the  Portfolio obtains the  contractual right to require  the issuer of the
     security or some other  person (other than a broker or dealer)  to purchase
     the security  at an  agreed upon  price, which  right is  contained in  the
     obligation itself rather  than in a separate  agreement with the  seller or

                                        B - 8
<PAGE>






     some other  person. Because  this right  is assignable  with the  security,
     which  is  readily marketable  and  valued  in  the  customary manner,  the
     Portfolio will not assign any separate value to such right.
        
     Liquidity and Protective Put Options
              The  Portfolio may also  enter into a separate  agreement with the
     seller  of the security  or some  other person  granting the  Portfolio the
     right to put the  security to the seller thereof or  the other person at an
     agreed upon price. The Portfolio intends to  limit this type of transaction
     to institutions (such  as banks or securities dealers) which the Investment
     Adviser believes  present minimal  credit risks  and 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 Portfolio or that selling
     institutions will be willing to permit the  Portfolio to exercise a put  to
     hedge against  rising  interest rates.  A separate  put option  may not  be
     marketable  or otherwise assignable,  and sale  of the security  to a third
     party or lapse of time with the put unexercised may terminate the right  to
     exercise the put. The Portfolio  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 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  put  options.
     Interest income  generated by certain  bonds having put  or demand features
     may not qualify as tax-exempt interest.
         
        
     Securities Lending
              The  Portfolio   may  seek  to  increase  its  income  by  lending
     portfolio securities  to broker-dealers  or other  institutional borrowers.
     Under  present  regulatory  policies  of  the Commission,  such  loans  are
     required  to  be  secured   continuously  by   collateral  in  cash,   cash
     equivalents  or  U.S.   Government  securities  held  by   the  Portfolio's
     custodian  and maintained on a current basis at an amount at least equal to
     the market value  of the securities loaned, which  will be marked to market
     daily. Cash  equivalents include short-term  municipal obligations as  well
     as taxable certificates of  deposit, commercial paper and  other short-term
     money  market instruments.  The Portfolio  would have  the right to  call a
     loan and obtain  the securities loaned at  any time on up  to five business
     days' notice. During the  existence of a loan, the  Portfolio will continue
     to  receive  the equivalent  of  the interest  paid  by the  issuer  on the
     securities loaned and will also receive  a fee, or all or a  portion of the
     interest on  investment of the  collateral, if any.  However, the Portfolio
     may pay lending  fees to such borrowers.  The Portfolio would not  have the
     right to vote  any securities having voting rights  during the existence of
     the loan, but would  call the loan in anticipation of an  important vote to
     be taken among  holders of the securities  or the giving or  withholding of

                                        B - 9
<PAGE>






     their  consent on a material matter affecting the investment. As with other
     extensions of credit there are risks  of delay in recovery or even loss  of
     rights in the  securities loaned if  the borrower of  the securities  fails
     financially. However, the loans will  be made only to  organizations deemed
     by the  Portfolio's management  to be  of good  standing and  when, in  the
     judgment of  the  Portfolio's management,  the  consideration that  can  be
     earned from  securities loans justifies  the attendant risk.  Distributions
     of any  income realized  by the  Portfolio from  securities  loans will  be
     taxable. Securities  lending  involves administration  expenses,  including
     finders'  fees.    If the  management  of  the  Portfolio decides  to  make
     securities loans,  it is intended  that the value of  the securities loaned
     would not exceed 30%  of the Portfolio's total assets. The Portfolio has no
     present intention of engaging in securities lending.
         
        
     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  Portfolio (or of securities that  the Portfolio
     expects to  purchase).  To  hedge against changes  in rates,  the Portfolio
     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 Portfolio 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 that is a member of  the relevant exchange.  The
     Portfolio may purchase and write call and  put options on futures contracts
     that  are traded on a United States or  foreign exchange or board of trade.
     The Portfolio 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 Portfolio's custodian  for the  benefit of  the
     futures  commission  merchant through  whom the  Portfolio 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  Portfolio from  closing out  positions and
     limiting its losses.
         
        
              The  Portfolio   will  engage  in  futures   and  related  options
     transactions  only  for  bona  fide  hedging  purposes  as  defined  in  or
     permitted  by CFTC  regulations.   The  Portfolio  will determine  that the
     price fluctuations  in the  futures contracts  and options  on futures  are
     substantially related  to  price fluctuations  in  securities held  by  the
     Portfolio or  that  it  expects  to  purchase.    The  Portfolio's  futures

                                        B - 10
<PAGE>






     transactions will be entered into  for traditional hedging purposes  - that
     is, futures  contracts will  be sold to  protect against  a decline in  the
     price of  securities that the Portfolio owns, or  futures contracts will be
     purchased to  protect the  Portfolio against  an increase in  the price  of
     securities it  intends to  purchase.  As  evidence of this  hedging intent,
     the  Portfolio expects  that on 75%  or more of  the occasions  on which it
     takes a  "long" futures  (or option)  position (involving  the purchase  of
     futures contracts), the  Portfolio will have purchased,  or will be  in the
     process of  purchasing,  equivalent amounts  of related  securities in  the
     cash market at the  time when  the futures (or  option) position is  closed
     out.   However, in particular  cases, when it  is economically advantageous
     for the Portfolio to  do so, a long futures position may  be terminated (or
     an  option may  expire) without  the corresponding  purchase of securities.
     The Portfolio  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  the qualification of each of the
     Portfolio's investment company investors as a  regulated investment company
     for federal income tax purposes (see "Tax Status").
         
        
              Transactions using  futures  contracts  and  options  (other  than
     options that  the  Portfolio has  purchased)  expose  the Portfolio  to  an
     obligation to another  party.  The Portfolio  will not enter into  any such
     transactions unless it owns  either (1) an offsetting  ("covered") position
     in  securities  or  other  options  or  futures  contracts,  or  (2)  cash,
     receivables and short-term debt securities  with a value sufficient  at all
     times to  cover its  potential obligations not  covered as provided  in (1)
     above.   The Portfolio  will  comply with  Commission guidelines  regarding
     cover  for these instruments and,  if the guidelines  so require, set aside
     cash,  U.S.  Government   securities  or  other  liquid,   high-grade  debt
     securities in a  segregated account with  its custodian  in the  prescribed
     amount.
         
        
              Assets used as  cover or  held in a segregated  account cannot  be
     sold while the position in  the corresponding futures contract or option is
     open,  unless they  are  replaced  with other  appropriate  assets.   As  a
     result, the  commitment of  a large  portion of  the Portfolio's assets  to
     cover  or segregated  accounts  could impede  portfolio  management or  the
     Portfolio's  ability   to  meet  redemption   requests  or  other   current
     obligations.
         
        
     Short-Term Obligations
              Although   the   Portfolio  will   normally   attempt   to  invest
     substantially  all of its  assets in  municipal obligations,  the Portfolio
     may, under  normal circumstances,  invest up to  20% of  its net assets  in
     short-term obligations the  interest on which is subject to regular federal
     income  tax  and/or  federal  alternative minimum  tax.    Such  short-term
     taxable obligations  may include, but  are not limited  to, certificates of
     deposit,  commercial paper,  short-term  notes  and obligations  issued  or
     guaranteed   by  the   U.S.   Government  or   any   of  its   agencies  or

                                        B - 11
<PAGE>






     instrumentalities.  During  periods  of  adverse   market  conditions,  the
     Portfolio  may  temporarily invest  more  than 20%  of  its assets  in such
     short-term taxable obligations, all of which will be high quality.
         
        
     Investment Restrictions
              The  Portfolio has adopted  the following  investment restrictions
     which  may  not be  changed  without  the  approval  of the  holders  of  a
     "majority of the  outstanding voting securities" of the Portfolio, which as
     used in this Part B means the lesser of (a) 67%  or more of the outstanding
     voting securities of  the Portfolio  present or represented  by proxy at  a
     meeting  if  the  holders  of  more  than  50%  of  the outstanding  voting
     securities of  the Portfolio are present  or represented at  the meeting or
     (b) more than 50%  of the outstanding voting  securities of the  Portfolio.
     The  term "voting  securities"  as  used in  this  paragraph has  the  same
     meaning as  in the  1940  Act.   As  a matter  of fundamental  policy,  the
     Portfolio may not:
         
        
         
              (1) Purchase  securities on margin  (but the  Portfolio may obtain
     such short-term credits as may be necessary for the clearance  of purchases
     and sales  of securities).   The  deposit or  payment by  the Portfolio  of
     initial or  maintenance  margin in  connection  with futures  contracts  or
     related options transactions is not  considered the purchase of  a security
     on margin;

              (2) Borrow  money or issue senior  securities except as  permitted
     by the Investment Company Act of 1940; 

              (3) Underwrite or  participate in the  marketing of  securities of
     others,  except  insofar  as  it  may  technically  be   deemed  to  be  an
     underwriter in selling a  portfolio security under circumstances  which may
     require the registration of the same under the Securities Act of 1933;

              (4) Purchase  or sell  real estate (including  limited partnership
     interests  in real estate,  but excluding  readily marketable  interests in
     real  estate  investment   trusts  or  readily  marketable   securities  of
     companies which  invest or  deal  in real  estate or  securities which  are
     secured by real estate);

              (5) Purchase  or sell  physical commodities or  contracts for  the
     purchase or sale of physical commodities; or

              (6) Make  loans to  any person except  by (a)  the acquisition  of
     debt  instruments  and  making portfolio  investments,  (b)  entering  into
     repurchase agreements, and (c) lending portfolio securities.

              For  purposes of  the  investment restrictions  listed  above, the
     determination of  the "issuer"  of a  municipal obligation  which is  not a
     general obligation  bond will  be made  by  the Investment  Adviser on  the
     basis of the  characteristics of the obligation and other relevant factors,

                                        B - 12
<PAGE>






     the most significant  of which is the source  of funds committed to meeting
     interest and principal payments of such obligation.
        
              The Portfolio has adopted  the following investment policies which
     may be  changed by the  Portfolio without approval  of its investors. As  a
     matter of  nonfundamental policy,  the Portfolio  will not:  (a) engage  in
     options, futures  or  forward transactions  if  more  than 5%  of  its  net
     assets,  as  measured  by  the  aggregate  of  the  premiums  paid  by  the
     Portfolio, would  be so  invested; (b)  make short sales  of securities  or
     maintain a short position,  unless at  all times when  a short position  is
     open it  owns an equal amount of  such securities or 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,  and unless  not more than  25% of  the Portfolio's net  assets
     (taken  at current value) is  held as collateral for  such sales at any one
     time (the Portfolio will make such sales only for the purpose of  deferring
     realization of gain  or loss for  federal income tax purposes);  (c) invest
     more  than 15%  of  its net  assets in  investments  which are  not readily
     marketable,  including  restricted  securities  and  repurchase  agreements
     maturing in  more than seven  days. Restricted securities  for the purposes
     of this limitation do not  include securities eligible for  resale pursuant
     to Rule 144A  under the Securities Act of  1933 and commercial paper issued
     pursuant to Section  4(2) of  said Act that  the Board  of Trustees of  the
     Portfolio, or  its  delegate, determines  to  be  liquid; (d)  purchase  or
     retain in its portfolio  any securities  issued by an  issuer any of  whose
     officers, directors, trustees  or security holders is an officer or Trustee
     of  the Portfolio  or  is a  member, officer,  director  or trustee  of any
     investment  adviser  of  the  Portfolio,  if  after  the  purchase  of  the
     securities of  such issuer  by the Portfolio  one or  more of such  persons
     owns beneficially more than  1/2 of 1% of the shares or  securities or both
     (all taken at market  value) of  such issuer and  such persons owning  more
     than 1/2 of 1% of such shares or  securities together own beneficially more
     than 5% of such shares  or securities or both (all taken at  market value);
     or (e) purchase oil,  gas or other  mineral leases or purchase  partnership
     interests  in  oil,  gas  or  other   mineral  exploration  or  development
     programs.
         
        
              Whenever an investment policy  or investment restriction set forth
     in Part A or this Part B 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   Portfolio's
     acquisition  of  such  security or  other  asset.  Accordingly,  any  later
     increase or  decrease resulting from  a change  in values, assets  or other
     circumstances,  other than  a  subsequent  rating change  below  investment
     grade made by  a rating service, will  not compel the Portfolio  to dispose
     of such  security  or other  asset.    Notwithstanding the  foregoing,  the
     Portfolio must always be in compliance with the borrowing  policy set forth
     above.

              In order  to  permit  the sale  in  certain states  of  shares  of
     certain open-end investment  companies that are investors in the Portfolio,
     the  Portfolio may  make  commitments more  restrictive  than the  policies
     described  above. Should  the Portfolio determine  that any such commitment
     is no  longer in the best interests of  the Portfolio and its investors, it
     will revoke such commitment.
         
        
     Item 14.  Management of the Portfolio
              The Trustees  and  officers of  the Portfolio  are  listed  below.

     A. JOHN MURPHY (33), Assistant Secretary
     Assistant Vice President  of BMR, Eaton Vance  and EV since March  1, 1994;

     The  Boston  Company  (1991-1993)  and  Registration  Specialist,  Fidelity
     Management &  Research  Co. (1986-1991).    Officer of  various  investment
     companies managed by Eaton Vance or BMR.  Mr. Murphy was elected  Assistant
     Secretary of the Portfolio on March 27, 1995.
         
        
     ERIC G. WOODBURY (39), Assistant Secretary
     Vice President  of BMR, Eaton Vance  and EV since February  1993; formerly,
     associate attorney at  Dechert Price & Rhoads  and Gaston & Snow.   Officer
     of  various investment  companies  managed  by Eaton  Vance  or  BMR.   Mr.

     1995.
         
        
              Messrs. Thorndike (Chairman), Hayes and  Reamer are members of the
     Special Committee of the  Board of Trustees of the Portfolio.   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 Portfolio,  including investment  advisory,
     custodial  and fund  accounting  services, and  (ii)  all other  matters in
     which Eaton Vance  or its affiliates  has any actual or  potential conflict
     of interest with the Portfolio or its interestholders. 
         
        
              The Nominating Committee is compromised  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 of the Portfolio.  Messrs. Hayes  (Chairman), Reamer,
     Thorndike and Treynor are currently serving on  the Committee.  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.    The Audit  Committee's  functions
     include  making recommendations to the  Trustees regarding the selection of
     the  independent certified  public  accountants,  and reviewing  with  such
     accountants and the  Treasurer of the Portfolio 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 of the Portfolio.

              The fees  and expenses of those Trustees of  the Portfolio who are
     not members  of the Eaton Vance  organization (the  noninterested Trustees)
     are paid by  the Portfolio.  (The Trustees of the Portfolio who are members
     of  the  Eaton  Vance   organization  receive  no  compensation  from   the
     Portfolio).    During   the  fiscal  year   ended  March   31,  1996,   the
     noninterested Trustees of  the Portfolio earned the  following compensation
     in  their capacities as Trustees  of the Portfolio  and in their capacities
     as trustees of the funds in the Eaton Vance fund complex(1):

     (5)      Includes $37,500 of deferred compensation.
         
        
              Trustees  of the  Portfolio who  are not  affiliated with  BMR 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
     "Plan").   Under  the Plan,  an  eligible Trustee  may  elect to  have  his
     deferred fees invested by the Portfolio in the shares  of one or more funds
     in the Eaton  Vance Family of  Funds, and the amount  paid to the  Trustees
     under the  Plan  will be  determined  based upon  the performance  of  such
     investments.  Deferral of Trustees' fees  in accordance with the Plan  will
     have a  negligible effect on  the Portfolio's assets,  liabilities, and net
     income  per share,  and  will  not obligate  the  Portfolio to  retain  the
     services of  any Trustee  or obligate the  Portfolio to pay  any particular
     level  of compensation  to the  Trustee.   The  Portfolio does  not have  a
     retirement plan for its Trustees.

              The  Portfolio's  Declaration  of  Trust  provides  that  it  will
     indemnify  its  Trustees  and officers  against  liabilities  and  expenses
     incurred in  connection  with litigation  in  which  they may  be  involved
     because of  their offices with  the Portfolio, unless,  as to liability  to
     the  Portfolio  or its  investors,  it  is  finally  adjudicated that  they
     engaged in  willful misfeasance, bad  faith, gross  negligence or  reckless
     disregard of the duties involved  in their offices, or unless  with respect
     to any other  matter it is  finally adjudicated  that they did  not act  in
     good  faith in the  reasonable belief that their  actions were  in the best
     interests   of  the   Portfolio.   In   the   case  of   settlement,   such
     indemnification will not  be provided  unless it has  been determined by  a
     court or other body  approving the settlement or other disposition, or by a
     reasonable determination, based upon  a review of readily available  facts,
     by vote of a majority of  noninterested Trustees or in a written opinion of
     independent counsel, that  such officers or  Trustees have  not engaged  in
     wilful misfeasance, bad  faith, gross negligence or  reckless disregard  of
     their duties.
        
     Item 15.  Control Persons and Principal Holder of Securities
              As  of  July  1,  1996,  EV  Marathon  National  Limited  Maturity
     Municipals  Fund  (the  "Marathon  Fund"),  EV   Classic  National  Limited
     Maturity Municipals Fund (the "Classic Fund"), and  EV Traditional National
     Limited Maturity Municipals  Fund (the  "Traditional Fund"), all  series of
     Eaton  Vance Investment Trust, owned  approximately 83.1%,  9.2%, and 7.7%,
     respectively, of the value of  the outstanding interests in  the Portfolio.
     Because  the Marathon  Fund  controls the  Portfolio,  it may  take actions
     without the approval of any other investor. The Marathon  Fund, the Classic
     Fund  and  the Traditional  Fund  have  each  informed  the Portfolio  that
     whenever it is requested to  vote on matters pertaining to  the fundamental
     policies of the Portfolio,  it will hold a meeting of shareholders and will
     cast its  votes as instructed by  its shareholders. It is  anticipated that
     any other  investor  in  the  Portfolio  which  is  an  investment  company
     registered under the 1940  Act would follow the same or a similar practice.
     Eaton  Vance Investment Trust is an  open-end management investment company
     organized  as a  business  trust under  the  laws  of the  Commonwealth  of
     Massachusetts.
         
        
     Item 16.  Investment Advisory and Other Services
              Investment Adviser.   The Portfolio engages BMR  as its investment
     adviser  pursuant to  an  Investment Advisory  Agreement dated  October 13,
     1992.  BMR  or  Eaton  Vance  acts  as  investment  adviser  to  investment
     companies and  various individual and  institutional clients with  combined
     assets under management of over $16 billion.
         
              BMR  manages the investments and affairs  of the Portfolio subject
     to the  supervision of the Portfolio's Board of  Trustees. BMR furnishes to
     the Portfolio  investment research,  advice and  supervision, furnishes  an
     investment program and determines  what securities will be purchased,  held
     or sold  by the  Portfolio and  what portion,  if any,  of the  Portfolio's
     assets will  be held uninvested. The Investment Advisory Agreement requires
     BMR  to pay  the salaries  and  fees of  all officers  and Trustees  of the

                                        B - 18
<PAGE>






     Portfolio who are members of the BMR organization and all personnel of  BMR
     performing services  relating to  research and  investment activities.  The
     Portfolio is  responsible  for all  expenses  not  expressly stated  to  be
     payable by BMR under the Investment Advisory  Agreement, including, without
     implied  limitation,  (i)   expenses  of  maintaining  the   Portfolio  and
     continuing  its existence,  (ii) registration  of  the Portfolio  under the
     1940 Act, (iii)  commissions, fees and  other expenses  connected with  the
     acquisition, holding and  disposition of securities and  other investments,
     (iv) auditing, accounting  and legal expenses, (v) taxes and interest, (vi)
     governmental  fees,  (vii)  expenses  of  issue,  sale  and  redemption  of
     interests in the Portfolio, (viii)  expenses of registering and  qualifying
     the Portfolio  and  interests in  the  Portfolio  under federal  and  state
     securities  laws and  of preparing and  printing registration statements or
     other  offering   statements  or  memoranda  for   such  purposes  and  for
     distributing the  same to investors,  and fees and  expenses of registering
     and  maintaining  registrations of  the  Portfolio and  of  the Portfolio's
     placement  agent as  broker-dealer or  agent under  state securities  laws,
     (ix)  expenses of  reports  and notices  to  investors and  of meetings  of
     investors and  proxy solicitations  therefor,  (x) expenses  of reports  to
     governmental officers  and  commissions,  (xi)  insurance  expenses,  (xii)
     association membership  dues, (xiii)  fees, expenses  and disbursements  of
     custodians and subcustodians for  all services to the Portfolio  (including
     without   limitation   safekeeping   for   funds,   securities  and   other
     investments, keeping of books,  accounts and records, and  determination of
     net asset values,  book capital account  balances and  tax capital  account
     balances),  (xiv) fees,  expenses  and  disbursements of  transfer  agents,
     dividend disbursing  agents, investor servicing  agents and registrars  for
     all services to the Portfolio, (xv) expenses for servicing the accounts  of
     investors, (xvi) any direct charges  to investors approved by  the Trustees
     of  the Portfolio,  (xvii)  compensation and  expenses  of Trustees  of the
     Portfolio who  are not members  of the BMR  organization, and (xviii)  such
     nonrecurring items as may arise, including expenses incurred in  connection
     with  litigation,   proceedings  and  claims  and  the  obligation  of  the
     Portfolio to indemnify  its Trustees, officers and  investors with  respect
     thereto.
        
              For a description of the compensation that the Portfolio pays  BMR
     under the Investment  Advisory Agreement, see "Management of the Portfolio"
     in  Part  A.   As  of  March 31,  1996, the  Portfolio  had  net assets  of
     $134,776,368.  For the fiscal years ended March 31, 1996 and 1995, and  for
     the period from the start of business,  May 3, 1993, to March 31, 1994, BMR
     earned  advisory fees  of  $717,356,  $817,082 and  $562,094,  respectively
     (equivalent to 0.47%,  0.46% and 0.46% (annualized),  respectively, of  the
     Portfolio's average daily net assets for such periods).  
         
        
              The  Investment  Advisory Agreement  with  BMR  remains  in effect
     until February  28, 1997.  It  may be continued indefinitely  thereafter so
     long  as such continuance is approved at  least annually (i) by the vote of
     a majority of the Trustees of the Portfolio  who are not interested persons
     of the Portfolio or of BMR cast in person  at a meeting specifically called
     for the  purpose  of voting  on  such approval  and (ii)  by  the Board  of

                                        B - 19
<PAGE>






     Trustees of  the Portfolio  or by  vote of  a majority  of the  outstanding
     voting  securities of the  Portfolio.  The  Agreement may  be terminated at
     any time without  penalty on sixty (60)  days' written notice by  the Board
     of Trustees of either party, or by vote of  the majority of the outstanding
     voting securities  of  the  Portfolio,  and the  Agreement  will  terminate
     automatically in the event of its assignment.  The Agreement provides  that
     BMR may render  services to others.   The Agreement also provides  that BMR
     shall  not  be  liable  for  any  loss  incurred  in  connection  with  the
     performance  of  its   duties,  or  action  taken  or  omitted  under  that
     Agreement,  in  the  absence  of  willful  misfeasance,  bad  faith,  gross
     negligence in the  performance of its duties  or by reason of  its reckless
     disregard  of its  obligations  and duties  thereunder,  or for  any losses
     sustained in the  acquisition, holding or  disposition of  any security  or
     other investment.
         
        
              BMR is a wholly-owned subsidiary of Eaton Vance.   Eaton Vance and
     EV are both  wholly-owned subsidiaries  of EVC.   BMR and  Eaton Vance  are
     both Massachusetts business trusts, and EV is the trustee of BMR and  Eaton
     Vance.  The Directors  of EV are Landon  T. Clay, H.  Day Brigham, Jr.,  M.
     Dozier  Gardner,  James  B. Hawkes,  and  Benjamin  A.  Rowland, Jr.    The
     Directors of EVC consist of the same  persons and John G.L. Cabot and Ralph
     Z.  Sorenson.  Mr. Clay is chairman  and Mr. Gardner is president and chief
     executive officer of EVC,  BMR, Eaton Vance and EV.  All of  the issued and
     outstanding  shares of Eaton  Vance and  EV 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,  which expires on  December 31,  1996, the Voting  Trustees of which
     are  Messrs.  Clay, Brigham,  Gardner,  Hawkes  and  Rowland.   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 and  Directors of EVC and EV.   As of June  30, 1996,
     Messrs. Clay,  Gardner  and Hawkes  each  owned 24%  of such  voting  trust
     receipts, and Messrs.  Rowland and Brigham owned 15% and 13%, respectively,
     of  such voting trust  receipts.  Messrs. Hawkes  and Otis  are officers or
     Trustees of the Portfolio  and are members of the EVC, BMR, Eaton Vance and
     EV organizations.   Messrs. Fetter, Hender, MacIntosh, Murphy, O'Connor and
     Woodbury  and Ms.  Sanders  are  officers of  the  Portfolio  and are  also
     members of the BMR,  Eaton Vance  and EV organizations.   BMR will  receive
     the fees paid under the Investment Advisory Agreement.
         
        
              EVC owns all of the stock of Energex  Energy Corporation, which is
     engaged in  oil and gas  exploration and  development.  In  addition, Eaton
     Vance  owns all  of  the stock  of  Northeast  Properties, Inc.,  which  is
     engaged in  real estate  investment.   EVC  also owns  24% of  the Class  A
     shares  of   Lloyd  George  Management   (B.V.I.)  Limited,  a   registered
     investment adviser.  EVC owns all of the stock of Fulcrum Management,  Inc.
     and  MinVen  Inc., which  are  engaged  in  precious  metal mining  venture
     investment  and management.   EVC, BMR, Eaton Vance  and EV  may also enter
     into other businesses.

              EVC and its affiliates and their officers and employees from  time
     to time  have transactions with  various banks, including  the custodian of
     the  Portfolio, Investors  Bank  &  Trust Company.    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 Portfolio and such banks.
        
              Custodian.   Investors  Bank &  Trust  Company  ("IBT"), 89  South
     Street, Boston,  Massachusetts, acts as  custodian for the  Portfolio.  IBT
     has the custody  of all  of the Portfolio's  assets, maintains the  general
     ledger  of the  Portfolio,  and  computes  the  daily net  asset  value  of
     interests  in the Portfolio.   In  such capacity  it attends to  details in
     connection with the sale, exchange,  substitution or transfer of,  or other
     dealings  with, the  Portfolio's investments,  receives  and disburses  all
     funds, and  performs  various  other ministerial  duties  upon  receipt  of
     proper  instructions  from the  Portfolio.    IBT  charges  fees which  are
     competitive within the industry.   A portion of the fee relates to custody,
     bookkeeping and  valuation  services and  is  based  upon a  percentage  of
     Portfolio net assets and a portion of the  fee relates to activity charges,
     primarily the  number  of portfolio  transactions.    These fees  are  then
     reduced by a credit  for cash  balances of the  Portfolio at the  custodian
     equal to 75% of the 91-day, U.S. Treasury Bill auction rate applied  to the
     Portfolio's  average daily  collected  balances for  the  week.   Landon T.
     Clay, a  Director of  EVC  and an  officer, Trustee  or Director  of  other
     entities in the  Eaton Vance organization,  owns approximately  13% of  the
     voting stock  of Investors  Financial Services  Corp., the  holding company
     parent of IBT.  Management believes that such ownership does not create  an
     affiliated person  relationship between  the Portfolio  and  IBT under  the
     1940 Act. 
         
              Independent Certified Public Accountants.   Deloitte & Touche LLP,
     125 Summer  Street, Boston,  Massachusetts, are  the independent  certified
     public  accountants of the Portfolio, providing  audit services, tax return
     preparation,  and   assistance  and  consultation   with  respect  to   the
     preparation of filings with the Commission.

     Item 17.  Brokerage Allocation and Other Practices
              Decisions   concerning  the   execution  of   portfolio   security
     transactions,  including  the selection  of  the market  and  the executing
     firm, are  made  by BMR.   BMR  is also  responsible for  the execution  of
     transactions for all other accounts managed by it.
        
              BMR places  the portfolio  security transactions of  the Portfolio
     and of all  other accounts  managed by it  for execution  with many  firms.
     BMR  uses  its best  efforts  to  obtain  execution  of portfolio  security
     transactions at  prices  that are  advantageous  to  the Portfolio  and  at
     reasonably competitive  spreads or  (when a  disclosed commission is  being
     charged)  at  reasonably competitive  commission  rates.   In  seeking such
     execution, BMR  will use  its best judgment  in evaluating  the terms of  a
     transaction  and  will  give  consideration  to  various  relevant  factors
     including, without  limitation, the size  and type of  the transaction, the

                                        B - 21
<PAGE>






     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  purchased  and sold  by  the
     Portfolio 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  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 prices is customarily referred to
     as the spread.  The Portfolio may  also purchase municipal obligations from
     underwriters,   the  cost  of  which  may   include  undisclosed  fees  and
     concessions to  the  underwriters.    While  it  is  anticipated  that  the
     Portfolio  will not  pay significant  brokerage  commissions in  connection
     with such portfolio  security transactions, 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  Portfolio  will  incur  a  brokerage
     commission.    Although  spreads  or  commissions   on  portfolio  security
     transactions will,  in the judgment  of BMR,  be reasonable in  relation to
     the value of  the services provided, spreads or commissions exceeding those
     that another firm  might charge may be  paid to firms who were  selected to
     execute transactions on  behalf of the  Portfolio and  BMR's other  clients
     for providing brokerage and research services to BMR.
         
        
              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 Portfolio may receive a commission that  is in excess of the amount  of
     commission another broker or dealer  would have charged for  effecting that
     transaction if  BMR  determines in  good  faith  that such  commission  was
     reasonable in relation  to the value of the brokerage and research services
     provided.   This determination  may be  made either  on the  basis of  that
     particular  transaction or on  the basis  of overall  responsibilities that
     BMR  and  its  affiliates  have  for  accounts  over  which  they  exercise
     investment discretion.   In  making any  such determination,  BMR 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, statistical and quotation  services, data, information
     and other services,  products and materials  that assist  such advisers  in
     the performance of their investment responsibilities  ("Research Services")
     from  broker-dealer  firms  that execute  portfolio  transactions  for  the
     clients  of  such  advisers  and   from  third  parties  with   which  such
     broker-dealers  have arrangements.    Consistent  with this  practice,  BMR
     receives Research  Services from  many broker-dealer  firms with  which BMR
     places  the  Portfolio's transactions  and  from third  parties  with which
     these broker-dealers  have arrangements.   These Research Services  include
     such matters as general economic  and market reviews, industry  and company
     reviews,   evaluations   of  securities   and   portfolio   strategies  and
     transactions and 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  BMR in  connection  with client  accounts
     other than those accounts that pay commissions  to such broker-dealer.  Any
     such  Research Service  may  be  broadly useful  and  of  value to  BMR  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 only 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 Portfolio  is not  reduced because  BMR receives
     such  Research Services.    BMR evaluates  the  nature and  quality of  the
     various  Research   Services  obtained  through   broker-dealer  firms  and
     attempts to allocate  sufficient commissions to  such firms  to ensure  the
     continued receipt of Research Services  that BMR believes are useful or  of
     value to it in rendering investment advisory services to its clients.
         
        
              Subject to the  requirement that BMR shall use its best efforts to
     seek and  execute portfolio  security transactions  at advantageous  prices
     and  at  reasonably   competitive  spreads  or  commission  rates,  BMR  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 any investment  company sponsored by BMR  or
     Eaton Vance.  This policy  is not inconsistent with a rule  of the National
     Association of Securities Dealers,  Inc. ("NASD"), which rule provides that
     no  firm  that  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 Portfolio
     may also be  appropriate for other  investment accounts  managed by BMR  or
     its affiliates.   BMR will attempt to allocate equitably portfolio security

                                        B - 23
<PAGE>






     transactions  among  the   Portfolio  and  the  portfolios   of  its  other
     investment  accounts purchasing  municipal  obligations whenever  decisions
     are  made to purchase or sell  securities by the Portfolio  and one or more
     of such other  accounts simultaneously.   In making  such allocations,  the
     main factors to be considered  are the respective investment  objectives of
     the  Portfolio and  such  other accounts,  the  relative size  of portfolio
     holdings of the  same or comparable  securities, the  availability of  cash
     for  investment by the Portfolio and such  accounts, the size of investment
     commitments  generally held  by  the Portfolio  and  such accounts  and the
     opinions  of the persons  responsible for  recommending investments  to the
     Portfolio  and  such  accounts.     While  this  procedure  could   have  a
     detrimental effect on the  price or amount  of the securities available  to
     the Portfolio  from time to time, it is the opinion  of the Trustees of the
     Portfolio that the  benefits available  from the BMR  organization outweigh
     any   disadvantage  that   may   arise   from  exposure   to   simultaneous
     transactions.   For the  fiscal year  ended March  31, 1996, the  Portfolio
     paid brokerage  commissions of $11,212  on portfolio security  transactions
     aggregating  approximately   $102,185,731  to  firms  which  provided  some
     research services  to BMR or  its affiliates (although  many of  such firms
     may have been selected in  any particular transaction primarily  because of
     their execution capabilities).  For  the fiscal year ended March 31,  1995,
     and for the period from  the start of business,  May 3, 1993, to March  31,
     1994,   the  Portfolio   paid  no   brokerage   commissions  on   portfolio
     transactions.
         
     Item 18.  Capital Stock and Other Securities
              Under  the  Portfolio's Declaration  of  Trust,  the  Trustees are
     authorized to issue interests in the Portfolio.  Investors are entitled  to
     participate pro rata  in distributions of  taxable income,  loss, gain  and
     credit  of the Portfolio.  Upon dissolution  of the Portfolio, the Trustees
     shall liquidate  the assets of the  Portfolio and apply and  distribute the
     proceeds thereof  as follows: (a)  first, to the  payment of all debts  and
     obligations  of   the  Portfolio  to   third  parties  including,   without
     limitation, the retirement  of outstanding debt, including any debt owed to
     holders of  record  of interests  in  the  Portfolio ("Holders")  or  their
     affiliates, and the expenses of liquidation, and  to the setting up of  any
     reserves  for contingencies  which  may be  necessary;  and (b)  second, in
     accordance with the Holders' positive  Book Capital Account balances  after
     adjusting Book  Capital Accounts  for certain  allocations provided in  the
     Declaration of Trust and in  accordance with the requirements  described in
     Treasury Regulations Section 1.704-1(b)(2)(ii)(b)(2).   Notwithstanding the
     foregoing, if the Trustees  shall determine that an immediate sale  of part
     or  all of  the assets  of  the Portfolio  would cause  undue  loss to  the
     Holders,  the Trustees,  in  order to  avoid such  loss, may,  after having
     given notification to all  the Holders, to  the extent not then  prohibited
     by the law  of any jurisdiction in  which the Portfolio  is then formed  or
     qualified and applicable  in the circumstances, either defer liquidation of
     and withhold  from distribution  for a  reasonable time any  assets of  the
     Portfolio  except  those necessary  to  satisfy the  Portfolio's  debts and
     obligations  or  distribute  the  Portfolio's  assets  to  the  Holders  in
     liquidation.   Interests in the  Portfolio have  no preference, preemptive,
     conversion or similar rights and  are fully paid and  nonassessable, except

                                        B - 24
<PAGE>






     as set forth below.   Interests  in the Portfolio  may not be  transferred.
     Certificates  representing an  investor's  interest  in the  Portfolio  are
     issued only upon the written request of a Holder.

              Each Holder is entitled  to vote  in proportion to  the amount  of
     its interest  in the  Portfolio.   Holders  do not  have cumulative  voting
     rights.   The Portfolio  is not  required and  has no current  intention to
     hold annual meetings  of Holders, but the  Portfolio will hold  meetings of
     Holders when  in the judgment of  the Portfolio's Trustees it  is necessary
     or desirable  to submit matters  to a vote  of Holders at  a meeting.   Any
     action which  may be taken  by Holders may  be taken  without a meeting  if
     Holders holding more  than 50% of all  interests entitled to vote  (or such
     larger proportion thereof  as shall be required by any express provision of
     the  Declaration  of  Trust of  the  Portfolio) consent  to  the  action in
     writing  and  the consents  are  filed  with  the records  of  meetings  of
     Holders.
        
              The Portfolio's  Declaration of Trust  may be amended  by vote  of
     Holders of more than 50% of all  interests in the Portfolio at any  meeting
     of Holders or by an instrument in writing without a  meeting, executed by a
     majority of the Trustees  and consented to by the Holders  of more than 50%
     of all interests.   The Trustees  may also amend  the Declaration of  Trust
     (without the vote or consent of Holders) to  change the Portfolio's name or
     the state or  other jurisdiction whose law  shall be the governing  law, to
     supply  any  omission  or   cure,  correct  or  supplement  any  ambiguous,
     defective or  inconsistent provision, to  conform the Declaration of  Trust
     to applicable  federal law  or regulations  or to  the requirements of  the
     Code,  or to change,  modify or  rescind any provision,  provided that such
     change, modification  or rescission  is determined  by the  Trustees to  be
     necessary or  appropriate and not  to have a  materially adverse  effect on
     the financial  interests of the Holders.   No amendment of  the Declaration
     of  Trust  which would  change  any  rights with  respect  to any  Holder's
     interest  in the  Portfolio  by reducing  the  amount payable  thereon upon
     liquidation of the  Portfolio may be made, except  with the vote or consent
     of the  Holders  of  two-thirds  of  all  interests.    References  in  the
     Declaration  of  Trust  and  in  Part A  or  this  Part  B  to a  specified
     percentage of,  or fraction of,  interests in the  Portfolio, means Holders
     whose  combined Book  Capital  Account  balances represent  such  specified
     percentage or  fraction of  the combined  Book Capital  Account balance  of
     all, or a specified group of, Holders.
         
              The   Portfolio  may   merge   or  consolidate   with   any  other
     corporation, association,  trust  or  other organization  or  may  sell  or
     exchange all  or  substantially  all of  its  assets  upon such  terms  and
     conditions  and  for such  consideration  when  and  as  authorized by  the
     Holders of (a)  67% or more of  the interests in  the Portfolio present  or
     represented at the meeting  of Holders, if Holders of more  than 50% of all
     interests are present or represented by proxy,  or (b) more than 50% of all
     interests, whichever is  less.  The Portfolio may  be terminated (i) by the
     affirmative vote of  Holders of not  less than two-thirds of  all interests
     at  any meeting  of  Holders  or by  an  instrument  in writing  without  a
     meeting,  executed  by a  majority  of the  Trustees  and  consented to  by

                                        B - 25
<PAGE>






     Holders of  not less  than  two-thirds of  all interests,  or (ii)  by  the
     Trustees by written notice to the Holders.

              In accordance with  the Declaration of Trust,  there normally will
     be no  meetings  of the  investors for  the  purpose of  electing  Trustees
     unless and until such time  as less than a majority of the Trustees holding
     office have been elected by  investors.  In such an event, the  Trustees of
     the Portfolio  then  in office  will  call an  investors'  meeting for  the
     election of Trustees.  Except  for the foregoing circumstances,  and unless
     removed  by action  of  the investors  in  accordance with  the Portfolio's
     Declaration of  Trust, the Trustees  shall continue to hold  office and may
     appoint successor Trustees.
        
              The Declaration of  Trust provides that no person shall serve as a
     Trustee if investors holding  two-thirds of the outstanding  interests have
     removed him  from that  office either by  a written declaration  filed with
     the Portfolio's  custodian or by  votes cast at  a meeting called for  that
     purpose.   The Declaration  of Trust  further provides  that under  certain
     circumstances, the  investors may call  a meeting to  remove a  Trustee and
     that the Portfolio  is required to provide assistance in communicating with
     investors about such a meeting.
         
              The Portfolio is organized as  a trust under the laws of the State
     of  New York.   Investors in the Portfolio  will be  held personally liable
     for its obligations  and liabilities, subject, however,  to indemnification
     by the  Portfolio in the  event that  there is imposed  upon an  investor a
     greater portion  of the liabilities  and obligations of  the Portfolio than
     its proportionate  interest in  the Portfolio.   The  Portfolio intends  to
     maintain fidelity  and errors and  omissions  insurance  deemed adequate by
     the Trustees.  Therefore,  the risk of an investor incurring financial loss
     on account of investor liability is limited  to circumstances in which both
     inadequate insurance exists and the Portfolio itself is  unable to meet its
     obligations.

              The Declaration of Trust  further provides that obligations of the
     Portfolio are not binding upon  the Trustees individually but only upon the
     property of the Portfolio  and that the Trustees will not be liable for any
     action or failure to act, but nothing in  the Declaration of Trust protects
     a Trustee against any liability 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.

     Item 19.  Purchase, Redemption and Pricing of Securities
              Interests in the Portfolio  are issued solely in private placement
     transactions that do not involve  any "public offering" within  the meaning
     of Section 4(2)  of the Securities Act of  1933. See "Purchase of Interests
     in the Portfolio" and "Redemption or Decrease of Interest" in Part A.
        
              The Portfolio's net asset value is determined by Investors Bank  &
     Trust Company  (as custodian  and agent  for the  Portfolio) in  the manner
     described in Part  A.  The net  asset value is computed by  subtracting the
     liabilities of the Portfolio from the value of its total assets.   Inasmuch

                                        B - 26

     as the market for municipal obligations is a dealer market with no  central
     trading location  or continuous  quotation system,  it is  not feasible  to
     obtain last transaction prices for  most municipal obligations held  by the
     Portfolio,  and   such  obligations,   including  those   purchased  on   a
     when-issued  basis, will  normally  be valued  on  the basis  of valuations
     furnished by a pricing service.  The pricing service uses information  with
     respect  to transactions  in bonds,  quotations from  bond  dealers, market
     transactions  in  comparable  securities,   various  relationships  between
     securities,   and  yield  to  maturity   in  determining  value.    Taxable
     obligations  for which price quotations are readily available normally will
     be valued at  the mean between the  latest available bid and  asked prices.
     Open futures  positions on debt  securities are  valued at the  most recent
     settlement prices unless such price does not reflect the fair value of  the
     contract,  in  which case  the  positions  will  be  valued by  or  at  the
     direction  of the Trustees  of the Portfolio.   Other assets  are valued at
     fair value using  methods determined in good  faith by or at  the direction
     of the Trustees.  
         
     Item 20.  Tax Status
              The Portfolio has  been advised by tax counsel that,  provided the
     Portfolio is operated at all times during its  existence in accordance with
     certain organizational and  operational documents, the Portfolio  should be
     classified as  a partnership under  the Internal  Revenue Code of  1986, as
     amended (the "Code"),  and it should not be a "publicly traded partnership"
     within the  meaning  of  Section  7704 of  the  Code.    Consequently,  the
     Portfolio does  not expect  that it  will be  required to  pay any  federal
     income  tax,  and  a  Holder will  be  required  to  take  into account  in
     determining its federal income tax  liability its share of  the Portfolio's
     income, gains, losses, deductions and tax preference items.
        
              Under Subchapter K of the  Code, a partnership is considered to be
     either an aggregate of its members or a  separate entity depending upon the
     factual  and  legal  context  in  which  the  question  arises.  Under  the
     aggregate approach,  each partner is  treated as  an owner of  an undivided
     interest in partnership  assets and operations. Under the  entity approach,
     the partnership is treated as a separate  entity in which partners have  no
     direct  interest in partnership  assets and  operations. The  Portfolio has
     been advised  by tax counsel that,  in the case of  a Holder that  seeks to
     qualify  as  a  regulated  investment  company  (a  "RIC"),  the  aggregate
     approach should  apply, and each  such Holder should  accordingly be deemed
     to own a proportionate share of each  of the assets of the Portfolio and to
     be  entitled to  the gross  income of  the Portfolio  attributable to  that
     share for purposes of all requirements of Sections  851(b) and 852(b)(5) of
     the Code. Further, the Portfolio has been advised  by tax counsel that each
     Holder that  seeks  to qualify  as  a RIC  should  be  deemed to  hold  its
     proportionate share of  the Portfolio's assets for the period the Portfolio
     has held  the assets or for the  period the Holder has  been an investor in
     the Portfolio,  whichever is  shorter. Investors  should consult their  tax
     advisers regarding whether  the entity or the aggregate approach applies to
     their investment in  the Portfolio in light of  their particular tax status
     and any special tax rules applicable to them.
         

                                        B - 27
<PAGE>






              In  order to  enable a Holder in  the Portfolio  that is otherwise
     eligible  to  qualify  as a  RIC,  the  Portfolio  intends  to satisfy  the
     requirements of Subchapter M  of the Code relating to sources of income and
     diversification of assets as  if they were applicable to the  Portfolio and
     to allocate and  permit withdrawals in a  manner that will enable  a Holder
     which is  a RIC  to comply  with those  requirements.   The Portfolio  will
     allocate at least  annually to each  Holder its  distributive share of  the
     Portfolio's  net taxable  (if any)  and tax-exempt  investment income,  net
     realized capital  gains,  and  any  other  items  of  income,  gain,  loss,
     deduction or  credit in  a  manner intended  to comply  with the  Code  and
     applicable  Treasury regulations.   Tax counsel  has advised  the Portfolio
     that the Portfolio's  allocations of taxable  income and  loss should  have
     "economic effect" under applicable Treasury regulations.

              To the  extent the  cash  proceeds of  any withdrawal  (or,  under
     certain  circumstances,  such proceeds  plus  the value  of  any marketable
     securities  distributed  to  an  investor)  ("liquid  proceeds")  exceed  a
     Holder's adjusted basis of his  interest in the Portfolio, the  Holder will
     generally realize  a  gain for  federal  income tax  purposes.  If, upon  a
     complete  withdrawal (redemption  of  the  entire interest),  the  Holder's
     adjusted basis  of  his  interest  exceeds  the  liquid  proceeds  of  such
     withdrawal, the Holder  will generally realize  a loss  for federal  income
     tax purposes.  The  tax consequences of  a withdrawal of property  (instead
     of or in addition  to liquid proceeds) will be different and will depend on
     the specific  factual  circumstances.   A  Holder's  adjusted basis  of  an
     interest  in the  Portfolio  will generally  be  the aggregate  prices paid
     therefor (including  the  adjusted basis  of contributed  property and  any
     gain recognized  on such  contribution), increased  by the  amounts of  the
     Holder's distributive share of items  of income (including interest  income
     exempt from  federal income tax)  and realized net  gain of  the Portfolio,
     and  reduced,  but not  below  zero, by  (i)  the amounts  of  the Holder's
     distributive share of items  of Portfolio loss, and (ii) the amount  of any
     cash distributions (including distributions of interest  income exempt from
     federal  income  tax  and   cash  distributions  on  withdrawals  from  the
     Portfolio) and  the basis to  the Holder of  any property received by  such
     Holder other  than  in liquidation,  and  (iii) the  Holder's  distributive
     share   of  the   Portfolio's   nondeductible  expenditures   not  properly
     chargeable to capital account.  Increases or decreases in  a Holder's share
     of the Portfolio's  liabilities may also result in  corresponding increases
     or decreases in such adjusted  basis.  Distributions of liquid  proceeds in
     excess of  a  Holder's adjusted  basis  in its  interest  in the  Portfolio
     immediately prior thereto  generally will result in the recognition of gain
     to the Holder in the amount of such excess.

              The Portfolio may acquire  zero coupon or other  securities issued
     with  original issue  discount.   As the  holder  of those  securities, the
     Portfolio must account for the  original issue discount (even  on municipal
     securities) that  accrues on the  securities during the  taxable year, even
     if it receives no corresponding payment on the securities  during the year.
     Because each  Holder that is  a RIC annually  must distribute substantially
     all of its  investment company taxable  income and  net tax-exempt  income,
     including  any original issue discount, to qualify  for treatment as a RIC,

                                        B - 28
<PAGE>






     any such Holder may  be required in a particular  year to distribute as  an
     "exempt-interest  dividend"  an  amount  that  is  greater  than  its  pro-
     portionate  share  of the  total  amount  of  cash  the Portfolio  actually
     receives.  Those distributions will be made  from the Holder's cash assets,
     if any, or from  its proportionate share of the Portfolio's cash  assets or
     the  proceeds of sales  of the  Portfolio's securities, if  necessary.  The
     Portfolio  may realize  capital  gains or  losses  from those  sales, which
     would increase  or decrease  the investment  company taxable income  and/or
     net capital gain (the  excess of net long-term capital gain over net short-
     term capital loss) of a Holder that is a RIC.   In addition, any such gains
     may be realized on  the disposition of securities held for less  than three
     months.   Because of the  Short-Short Limitation (defined  below), any such
     gains would reduce  the Portfolio's ability  to sell  other securities,  or
     options  or futures  contracts, held  for less  than three  months  that it
     might wish to sell in the ordinary course of its portfolio management.

              Investments  in  lower rated  or  unrated  securities  may present
     special  tax issues  for  the Portfolio  and hence  to  an investor  in the
     Portfolio  to the extent actual or anticipated  defaults may be more likely
     with respect to  such securities.  Tax  rules are not entirely  clear about
     issues such as  when the Portfolio may  cease to accrue interest,  original
     issue discount, or market discount; when and to what extent  deductions may
     be taken for bad  debts or worthless  securities; how payments received  on
     obligations  in default should be  allocated between  principal and income;
     and whether  exchanges  of  debt  obligations  in  a  workout  context  are
     taxable.

              In order for a  Holder that  is a RIC  to be entitled  to pay  the
     tax-exempt   interest   income   the   Portfolio   allocates   to   it   as
     exempt-interest  dividends to  its shareholders,  the  Holder must  satisfy
     certain requirements, including  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  excludable from  gross
     income  under Section  103(a)  of  the  Code.   The  Portfolio  intends  to
     concentrate its  investments in  such tax-exempt  obligations to an  extent
     that will enable a  RIC that invests its investable assets in the Portfolio
     to satisfy this 50% requirement.  

              Interest  on certain  municipal obligations  is  treated as  a tax
     preference  item  for  purposes of  the  federal  alternative minimum  tax.
     Holders  that are required to file federal  income tax returns are required
     to report  tax-exempt interest allocated to  them by the Portfolio  on such
     returns.

              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.
     Under  federal tax  legislation  enacted in  1986,  the federal  income tax
     exemption for  interest on certain municipal  obligations was eliminated or
     restricted.    As  a  result  of  such  legislation,  the  availability  of
     municipal obligations for investment  by the Portfolio and the value of the

                                        B - 29

     Portfolio may be affected.
        
              In  the course  of  managing  its investments,  the  Portfolio may
     realize some  short-term and long-term  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  Portfolio  may also  realize  taxable income  from  certain short-term
     taxable  obligations,  securities  loans,  a  portion   of  original  issue
     discount with  respect to  certain stripped municipal  obligations or their
     stripped  coupons  and certain  realized  gains or  income  attributable to
     accrued market  discount.  Any  allocations of such capital  gains or other
     taxable income to Holders would be taxable  to Holders that are subject  to
     tax.   However, it is expected that such amounts, if any, would normally be
     insubstantial  in  relation  to  the  tax-exempt  interest  earned  by  the
     Portfolio.
         
              The  Portfolio's  transactions in  options  and  futures contracts
     will  be subject to  special tax rules that  may affect  the amount, timing
     and  character  of  its  items  of  income,  gain  or loss  and  hence  the
     allocations of such  items to investors.   For  example, certain  positions
     held by the Portfolio on  the last business day  of each taxable year  will
     be marked to market  (i.e., treated as if closed out  on such day), and any
     resulting gain or loss  will generally be treated as 60% long-term  and 40%
     short-term capital gain or loss.   Certain positions held by the  Portfolio
     that substantially  diminish the Portfolio'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  Portfolio  losses,
     adjustments in the holding  period of  Portfolio securities and  conversion
     of short-term into long-term capital losses.  

              Income from transactions in  options and futures contracts derived
     by the Portfolio  with respect to its  business of investing in  securities
     will qualify as permissible  income for its Holders that are RICs under the
     requirement that at least  90% of  a RIC's gross  income each taxable  year
     consist of  specified types of  income.   However, income  from the  dispo-
     sition by  the Portfolio  of options and  futures contracts  held for  less
     than three  months will be subject  to the requirement applicable  to those
     Holders  that less  than 30%  of a  RIC's  gross income  each taxable  year
     consist of certain short-term gains ("Short-Short Limitation").

              If the  Portfolio satisfies certain requirements,  any increase in
     value of a position that is part of a "designated hedge"  will be offset by
     any decrease in value (whether  realized or not) of the offsetting  hedging
     position  during  the period  of  the  hedge  for  purposes of  determining
     whether the  Holders  that are  RICs  satisfy the  Short-Short  Limitation.
     Thus,  only the  net  gain  (if any)  from  the  designated hedge  will  be
     included in gross income  for purposes of that  limitation.  The  Portfolio
     will consider whether it  should seek to qualify for this treatment for its
     hedging transactions.  To the extent the Portfolio does not so qualify,  it
     may be  forced to defer  the closing out  of options and futures  contracts
     beyond the time when it otherwise would be advantageous  to do so, in order
     for Holders that are RICs to continue to qualify as such.

              Interest  on indebtedness incurred or continued  by an investor to
     purchase or carry an  investment in the Portfolio is not deductible  to the
     extent it is  deemed attributable to the investor's investment, through the
     Portfolio,  in   tax-exempt  obligations.     Further,   persons  who   are
     "substantial  users"  (or  persons  related  to   "substantial  users")  of
     facilities financed  by industrial  development or  private activity  bonds
     should consult  their  tax  advisers before  investing  in  the  Portfolio.
     "Substantial  user"  is  defined  in  applicable  Treasury  regulations  to
     include a  "non-exempt person" who  regularly uses in  trade or business  a
     part of a  facility financed from  the proceeds  of industrial  development
     bonds and would  likely be interpreted  to include  private activity  bonds
     issued to finance similar facilities.

              An entity that  is treated as a  partnership under the Code,  such
     as the  Portfolio, is generally  treated as a  partnership under state  and
     local   tax   laws,  but   certain   states  may   have   different  entity
     classification criteria  and may  therefore reach  a different  conclusion.
     Entities that  are classified as  partnerships are not  treated as separate
     taxable entities under most state and local  tax laws, and the income of  a
     partnership is considered  to be income of  partners both in timing  and in
     character.    The exemption  of  interest  income  for  Federal income  tax
     purposes does  not necessarily result in exemption  under the income or tax
     laws  of any  state or  local taxing  authority.   The laws  of the various
     states and  local taxing authorities vary  with respect to  the taxation of
     such interest income,  as well as to  the status of a  partnership interest
     under state and  local tax  laws, and  each holder  of an  interest in  the
     Portfolio is advised to consult his own tax adviser.

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

     Item 21.  Underwriters
              The   placement   agent  for   the   Portfolio   is   Eaton  Vance
     Distributors, Inc.,  which receives  no compensation  for  serving in  this
     capacity.  Investment companies,  common  and  commingled trust  funds  and
     similar  organizations  and   entities  may  continuously  invest   in  the
     Portfolio.

     Item 22.  Calculation of Performance Data
              Not applicable.
        
     Item 23.  Financial Statements
              The following  audited financial  statements of the  Portfolio are
     incorporated by  reference into this Part  B and have been  so incorporated
     in  reliance  upon the  report  of  Deloitte  and  Touche LLP,  independent
     certified public accountants, as experts in accounting and auditing.

                                       APPENDIX

                          Description of Securities Ratings+

                           Moody's Investors Service, Inc.

     Municipal Bonds

     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 edged."  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 fundamentally  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  risk appear
     somewhat larger than the 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
     payments  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  other good and  bad times over  the future. Uncertainty
     of position characterizes bonds in this class.

     ---------------
     + The ratings  indicated herein are believed to  be the most recent ratings
        available  at the date  of this Statement of  Additional Information for
        the  securities listed. Ratings are generally given to securities at the
        time  of issuance.  While the  rating  agencies may  from  time to  time
        revise  such ratings,  they undertake no  obligation to  do so,  and the
        ratings  indicated do  not necessarily represent ratings  which would be
        given  to these securities  on the date  of the Portfolio's  fiscal year

                                        a - 1

        end.

     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.

     Absence of Rating: Where no rating has been assigned or  where a rating has
     been  suspended  or withdrawn,  it  may  be for  reasons  unrelated to  the
     quality of the issue.

     Should no rating be assigned, the reason may be one of the following:

              1. An application for rating was not received or accepted.

              2. The issue or issuer belongs to a group of securities or
                  companies that are not rated as a matter of policy.

              3. There is a lack of essential data pertaining to the issue or
                  issuer.

              4. The issue was privately placed, in which case the rating is
                  not published in Moody's publications.

     Suspension  or withdrawal  may  occur  if  new and  material  circumstances
     arise, the effects of which preclude satisfactory analysis; if  there is no
     longer available  reasonable up-to-date  data to  permit a  judgment to  be
     formed; if a bond is called for redemption; or for other reasons.

     Note: Moody's  applies numerical  modifiers, 1,  2, and 3  in each  generic
     rating classification  from  Aa through  B  in  its corporate  bond  rating
     system. The modifier 1 indicates that the security  ranks in the higher end
     of its  generic  rating category;  the  modifier  2 indicates  a  mid-range
     ranking; and the modifier  3 indicates  that the issue  ranks in the  lower
     end of its generic rating category.

     Municipal Short-Term Obligations

     Ratings: Moody's  ratings for  state and  municipal short-term  obligations
     will  be  designated  Moody's   Investment  Grade  or  (MIG).  Such  rating

                                        a - 2
<PAGE>






     recognizes the differences  between short term  credit risk  and long  term
     risk. Factors  effecting  the liquidity  of  the  borrower and  short  term
     cyclical elements are critical in  short term ratings, while  other factors
     of major  importance in bond  risk, long term  secular trends for  example,
     may be less important over the short run.

     A  short  term rating  may also  be assigned  on an  issue having  a demand
     feature,  variable rate  demand  obligation (VRDO).  Such  ratings will  be
     designated as VMIG1, SG or  if the demand feature is not rated, NR. A short
     term rating on  issues with demand features  are differentiated by the  use
     of  the  VMIG1 symbol  to  reflect  such  characteristics  as payment  upon
     periodic demand rather  than fixed maturity  dates and  payment relying  on
     external  liquidity. Additionally,  investors should  be alert  to the fact
     that the source  of payment may be  limited to the external  liquidity with
     no or limited legal  recourse to the issuer in the  event the demand is not
     met.
        
         
        
                                  Standard & Poor's 
         
     Investment Grade

     AAA:  Debt rated AAA  has the highest rating  assigned by  S&P. Capacity to
     pay interest and repay principal is extremely strong.

     AA: Debt  rated AA  has a very  strong capacity to  pay interest  and repay
     principal and differs from the highest rated issues only in small degree.

     A: Debt rated A  has a strong capacity to pay interest  and repay principal
     although it is somewhat more susceptible to  the adverse effects of changes
     in  circumstances  and  economic  conditions  than  debt  in  higher  rated
     categories.

     BBB: Debt  rated BBB  is regarded  as having  an adequate  capacity to  pay
     interest  and  repay  principal.  Whereas  it   normally  exhibit  adequate
     protection   parameters,    adverse   economic   conditions   or   changing
     circumstances  are  more  likely to  lead  to  a weakened  capacity  to pay
     interest and  repay principal  for  debt in  this category  than in  higher
     rated categories.

     Speculative Grade

     Debt  rated BB,  B, CCC,  CC, and  C  is regarded  as having  predominantly
     speculative characteristics  with respect  to capacity to  pay interest and
     repay  principal. BB indicates  the least degree  of speculation  and C the
     highest.  While such  debt  will likely  have  some quality  and protective
     characteristics,  these are  outweighed  by  large uncertainties  or  major
     exposures to adverse conditions.

     BB:  Debt rated BB has  less near-term vulnerability  to default than other
     speculative  issues.  However,  it faces  major  ongoing  uncertainties  or

                                        a - 3
<PAGE>






     exposure  to adverse  business,  financial,  or economic  conditions  which
     could lead to  inadequate capacity to  meet timely  interest and  principal
     payments. The  BB rating  category is also  used for  debt subordinated  to
     senior debt that is assigned an actual or implied BBB- rating.

     B: Debt rated  B has a greater  vulnerability to default but  currently has
     the capacity to  meet interest payments and  principal repayments.  Adverse
     business, financial, or economic conditions will  likely impair capacity or
     willingness to pay interest  and repay principal. The B rating  category is
     also used for  debt subordinated to senior debt  that is assigned an actual
     or implied BB or BB- rating.

     CCC: Debt rated  CCC has a currently identifiable vulnerability to default,
     and  is  dependent   upon  favorable  business,  financial,   and  economic
     conditions to meet timely payment  of interest and repayment  of principal.
     In the event of adverse business, financial, or economic  conditions, it is
     not likely to  have the capacity to  pay interest and repay  principal. The
     CCC rating category is  also used for debt subordinated to senior debt that
     is assigned an actual or implied B or B- rating.

     CC: The rating CC  is typically applied to debt subordinated to senior debt
     which is assigned an actual or implied CCC debt rating.

     C: The rating  C is typically applied  to debt subordinated to  senior debt
     which is assigned an  actual or implied CCC- debt rating. The  C rating may
     be used to  cover a situation where  a bankruptcy petition has  been filed,
     but debt service payments are continued.

     C1:  The Rating C1  is reserved for  income bonds  on which no  interest is
     being paid.

     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 S&P 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  if debt  service
     payments 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.

     p: The letter "p" indicates  that the rating is provisional. A  provisional
     rating assumes the successful completion  of the project being  financed by
     the  debt  being  rated  and   indicates  that  payment  of   debt  service
     requirements  is  largely or  entirely  dependent upon  the  successful and
     timely completion  of the project. This  rating, however,  while addressing
     credit quality  subsequent to completion  of the project,  makes no comment
     on the  likelihood  of,  or  the  risk of  default  upon  failure  of  such
     completion. The investor should exercise  his own judgment with  respect to
     such likelihood and risk.


                                        a - 4
<PAGE>






     L:  The letter  "L" indicates  that  the rating  pertains to  the principal
     amount of those  bonds to the extent that the underlying deposit collateral
     is  insured  by  the  Federal  Deposit  Insurance  Corp.  and  interest  is
     adequately  collateralized.  In the  case of  certificates of  deposit, the
     letter "L" indicates that the  deposit, combined with other  deposits being
     held in the  same right  and capacity, will  be honored  for principal  and
     accrued pre-default interest up to  the federal insurance limits  within 30
     days after  closing of the  insured institution or,  in the event that  the
     deposit is assumed by a successor insured institution, upon maturity.

     NR: NR  indicates no rating has been  requested, that there is insufficient
     information  on which  to  base a  rating,  or that  S&P  does not  rate  a
     particular type of obligation as a matter of policy.

     Municipal Notes

     S&P note ratings  reflect the liquidity  concerns and  market access  risks
     unique to notes.  Notes due in 3  years or less will likely  receive a note
     rating. Notes maturing beyond  3 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).

              --  Sources 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.  Those  issues
     determined to possess very strong  characteristics will be 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.

     Investment Grade Bond Ratings

     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.


                                        a - 5

     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
     obligors 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.

     High Yield Bond Ratings

     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
     that 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.

     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,  DD,  and  D:  Bonds  are in  default  on  interest  and/or  principal
     payments. Such bonds are extremely speculative and should be valued  on the
     basis of their  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 (-): The  ratings from AA  to C may  be modified by the
     addition  of a plus  or minus sign  to indicate the  relative position of a
     credit within the rating category.


                                        a - 6

     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.

     Investment Grade Short-Term Ratings

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

     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  carrying this rating have  a satisfactory
     degree of  assurance for timely payment, but the margin of safety is not as
     great as the `F-1+' and `F-1' categories.

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

     * * * * * * * *

     Notes: Bonds  which are unrated expose  the investor to risks  with respect
     to capacity  to pay interest  or repay principal  which are similar to  the
     risks of lower-rated speculative bonds.  The Portfolio is dependent  on the
     Investment Adviser's  judgment, analysis and  experience in the  evaluation
     of such bonds.

              Investors should  note that the  assignment of a rating  to a bond
     by a rating  service may not reflect  the effect of recent  developments on
     the issuer's ability to make interest and principal payments.

                          AMENDMENT TO DECLARATION OF TRUST

                                   December 8, 1995



              AMENDMENT, made December 8, 1995 to the Declaration of Trust  made
     May 1,  1992,  as  amended  February  22,  1993,  (hereinafter  called  the

              WHEREAS, Section 10.4  of Article X of the Declaration  empowers a

                                     AMENDMENT TO
                              MASTER CUSTODIAN AGREEMENT
                                       between 
                             EATON VANCE HUB PORTFOLIOS 
                                         and
                            INVESTORS BANK & TRUST COMPANY

              This Amendment,  dated as  of  October 23,  1995, is  made to  the
     MASTER  CUSTODIAN  AGREEMENT  (the  "Agreement")  between  each  investment
     company advised by  Boston Management and  Research which  has adopted  the
     Agreement  (the  "Trusts")  and  Investors   Bank  &  Trust  Company   (the
     "Custodian") pursuant to Section 10 of the Agreement.

              The  Trusts  and  the Custodian  agree  that  Section  10  of  the
     Agreement shall, as of October 23, 1995, be amended to read as follows:

              Unless otherwise  defined herein, terms  which are  defined in the
     Agreement and used herein are so used as so defined.

     10.      Effective Period, Termination and Amendment; Successor Custodian

              This Agreement shall  become effective as of  its execution, shall
     continue in full force  and effect until  terminated by either party  after
     August 31,  2000 by an instrument  in writing delivered  or mailed, postage
     prepaid to  the other  party, such termination  to take  effect not  sooner
     than sixty (60) days after the date of  such delivery or mailing; provided,
     that  the Trust  may at  any time by  action of  its Board,  (i) substitute
     another  bank or  trust  company  for the  Custodian  by  giving notice  as
     described  above to the Custodian  in the event  the Custodian assigns this
     Agreement to  another party without  consent of the noninterested  Trustees
     of the Trust, or (ii) immediately terminate this Agreement in the event  of
     the  appointment  of a  conservator or  receiver for  the Custodian  by the
     Federal Deposit  Insurance Corporation or  by the  Banking Commissioner  of
     The Commonwealth of Massachusetts or upon the happening of a like event  at
     the direction of  an appropriate regulatory  agency or  court of  competent
     jurisdiction.  Upon termination  of the Agreement, the  Trust shall pay  to
     the Custodian  such compensation  as may  be due  as  of the  date of  such
     termination (and  shall likewise  reimburse the  Custodian  for its  costs,
     expenses and disbursements).

              This  Agreement  may  be  amended  at  any  time  by  the  written
     agreement  of the  parties hereto.   If  a majority  of the  non-interested
     trustees  of  any of  the Trusts  determines  that the  performance  of the
     Custodian has  been unsatisfactory  or adverse  to the  interests of  Trust
     holders of any  Trust or Trusts or that  the terms of the Agreement  are no
     longer  consistent with  publicly available  industry  standards, then  the
     Trust or  Trusts  shall  give  written notice  to  the  Custodian  of  such
     determination and  the Custodian  shall have  60 days to  (1) correct  such
     performance  to  the satisfaction  of  the non-interested  trustees  or (2)
     renegotiate terms which are satisfactory to the non-interested trustees  of
     the Trusts.  If  the conditions of the preceding sentence are  not met then
     the  Trust  or Trusts  may  terminate this  Agreement  on  sixty (60)  days
     written notice.
<PAGE>






              The Board of the Trust shall, forthwith, upon giving or  receiving
     notice of termination  of this Agreement, appoint as successor custodian, a
     bank or trust  company having the qualifications required by the Investment
     Company  Act of 1940  and the  Rules thereunder.   The Bank,  as Custodian,
     Agent or  otherwise, shall, upon  termination of the  Agreement, deliver to
     such successor custodian,  all securities then held hereunder and all funds
     or  other  properties of  the  Trust deposited  with  or held  by  the Bank
     hereunder and all  books of account and  records kept by the  Bank pursuant
     to this  Agreement, and all  documents held by  the Bank relative  thereto.
     In the event that no written order designating  a successor custodian shall
     have  been  delivered  to  the  Bank  on  or  before  the  date  when  such
     termination shall become  effective, then the  Bank shall  not deliver  the
     securities, funds and other properties of the Trust to the Trust but  shall
     have the  right to  deliver to a  bank or trust  company doing  business in
     Boston, Massachusetts  of  its own  selection  meeting the  above  required
     qualifications, all funds, securities and  properties of the Trust  held by
     or deposited with  the Bank, and all  books of account and records  kept by
     the  Bank pursuant to  this Agreement, and all  documents held  by the Bank
     relative thereto.   Thereafter  such bank  or trust  company  shall be  the
     successor of the Custodian under this Agreement.

              Except as  expressly provided  herein, the Agreement  shall remain
     unchanged and in full force and effect.

              IN WITNESS  WHEREOF, the parties hereto have caused this Amendment
     to be executed by  their duly authorized officers,  as of the day  and year
     first above written.
