                            SUBJECT TO COMPLETION
               PRELIMINARY PROSPECTUS DATED SEPTEMBER 24, 1998
                                                      SHARES

                       EATON VANCE SENIOR INCOME TRUST
                                -------------

      Eaton  Vance  Senior  Income  Trust (the  "Trust")  is a newly  organized,
non-diversified,   closed-end   management   investment  company.   The  Trust's
investment  objective is to provide a high level of current  income,  consistent
with preservation of capital,  by investing primarily in senior secured floating
rate  loans  ("Senior  Loans").  Due  to  the  floating  rate  nature  of  these
investments,  investment in Senior Loans is expected to minimize  changes in the
underlying  principal  value,  and therefore the Trust's net asset value, due to
changes in market interest rates. Nevertheless,  the Trust's net asset value and
distribution  rate will vary, and may be affected by several factors,  including
changes in the credit quality of the borrowers of Senior Loans.  Fluctuations in
net asset value may be magnified as a result of the Trust's use of leverage.  An
investment in the Trust may not be appropriate for all investors and there is no
assurance that the Trust will achieve its investment objectives.

      Senior Loans are made to  corporations,  partnerships  and other  business
entities  ("Borrowers")  which operate in various  industries  and  geographical
regions. Senior Loans pay interest at rates which are redetermined  periodically
on the basis of a  floating  base  lending  rate plus a  premium.  Senior  Loans
generally  hold  the  most  senior  position  in the  capital  structure  of the
borrower,  are secured  with  specific  collateral  and will have a claim on the
assets of the borrower that is senior to that of  subordinated  debt,  preferred
stock  and  common  stock  of the  borrower.  The  Trust  offers  investors  the
opportunity to receive current income through a professionally managed portfolio
of Senior Loans which is normally accessible only to financial  institutions and
large  corporate  and  institutional  investors  and is not widely  available to
individual investors. See "Investment Objective Policies and Risks."

      The Trust's  investment adviser is Eaton Vance Management (the "Adviser").
The Adviser was one of the first  investment  advisers to manage a portfolio  of
Senior  Loans  in a  publicly  offered  investment  company,  and  has  done  so
continuously since 1989

      The Trust is offering shares of beneficial  interest,  par value $0.01 per
share  ("Shares").  Prior to this  offering,  there has been no  market  for the
Trust's Shares.  The Trust has applied for listing of its Shares on the New York
Stock  Exchange  under the symbol  ______.  The shares of closed-end  investment
companies,  such as the Trust, have frequently traded at a discount to their net
asset  values.  Investors  in this  offering  should  note that the  Shares  may
likewise  trade at a discount to net asset  value.  This risk may be greater for
investors who sell their Shares in a relatively short period after completion of
the public offering.

      IN CONNECTION  WITH THIS  OFFERING,  THE  UNDERWRITERS  MAY  OVER-ALLOT OR
EFFECT  TRANSACTIONS  WHICH STABILIZE OR MAINTAIN THE MARKET PRICE OF THE SHARES
OF THE TRUST AT A LEVEL  ABOVE THAT WHICH  MIGHT  OTHERWISE  PREVAIL IN THE OPEN
MARKET. SUCH TRANSACTIONS MAY BE EFFECTED ON THE NEW YORK STOCK EXCHANGE, IN THE
NASDAQ  MARKET  OR  OTHERWISE.   SUCH  STABILIZATION,   IF  COMMENCED,   MAY  BE
DISCONTINUED AT ANY TIME.



(CONTINUED FROM COVER PAGE)

      The Trust  expects  to  utilize  financial  leverage  through  borrowings,
including the issuance of debt  securities,  or the issuance of preferred shares
or through other transactions, such as reverse repurchase agreements, which have
the  effect of  financial  leverage.  The Trust  intends  to  utilize  financial
leverage in an amount up to 33 1/3 % of its total assets  (including  the amount
obtained  through  leverage).  The Trust intends to utilize leverage if it would
result in higher income to  Shareholders  over time.  Use of financial  leverage
creates an  opportunity  for  increased  income but,  at the same time,  creates
special  risks.  There can be no assurance  that a leveraging  strategy  will be
successful.  SEE "INVESTMENT  OBJECTIVES,  POLICIES AND RISKS - USE OF LEVERAGE"
AND "DESCRIPTION OF CAPITAL STRUCTURE."

                              PROSPECTUS SUMMARY

      THE  FOLLOWING  SUMMARY IS  QUALIFIED  IN ITS ENTIRETY BY REFERENCE TO THE
MORE  DETAILED  INFORMATION  INCLUDED  ELSEWHERE  IN  THIS  PROSPECTUS  AND  THE
STATEMENT OF ADDITIONAL INFORMATION.

THE TRUST...........................Eaton  Vance   Senior   Income  Trust  (the
                                    "Trust")    is    a    newly     organized,
                                    non-diversified,    closed-end   management
                                    investment   company.   The  Trust   offers
                                    investors   the   opportunity   to  receive
                                    current  income  through  a  professionally
                                    managed   portfolio   of   senior   secured
                                    floating rate loans ("Senior Loans),  which
                                    is normally  accessible  only to  financial
                                    institutions   and  large   corporate   and
                                    institutional  investors, and is not widely
                                    available  to  individual   investors.   An
                                    investment   in  the   Trust   may  not  be
                                    appropriate  for all investors and there is
                                    no  assurance  that the Trust will  achieve
                                    its investment objective.

THE OFFERING........................The Trust is offering
                                    shares of  bene-ficial  interest,  par value
                                    $.01 per  share  (the  "Shares"),  through a
                                    group of underwriters  (the  "Underwriters")
                                    represented by . The Underwriters  have been
                                    granted   an  option  to   purchase   up  to
                                    additional    Shares    solely    to   cover
                                    over-allotments,  if any. The initial public
                                    offering  price is  $10.00  per  share.  The
                                    minimum  purchase  in this  offering  is 100
                                    shares ($1,000).

INVESTMENT                          OBJECTIVE   AND    POLICIES...The    Trust's
                                    investment  objective  is to  provide a high
                                    level of  current  income,  consistent  with
                                    preservation   of  capital,   by   investing
                                    primarily"  in Senior  Loans.  Senior  Loans
                                    generally  pay  interest  at rates which are
                                    redetermined  periodically by reference to a
                                    base  lending  rate,   such  as  the  London
                                    Inter-Bank  Offered Rate  ("LIBOR"),  plus a
                                    premium.  In normal  market  conditions,  at
                                    least 80% of the Trust's  total  assets will
                                    be invested in interests in Senior Loans. It
                                    is  anticipated  that  the  proceeds  of the
                                    Senior Loans in which the Trust will acquire
                                    interests  primarily will be used to finance
                                    leveraged    buyouts,     recapitalizations,
                                    mergers,  acquisitions and stock repurchases
                                    and, to a lesser extent, to finance internal
                                    growth and for other  corporate  purposes of
                                    borrowers.

                                    Although  Senior  Loans have the most senior
                                    position in a borrower's  capital  structure
                                    and are secured by specific collateral, they
                                    are  typically  of  below  investment  grade
                                    quality and may have below  investment grade
                                    ratings,   which   ratings   are   typically
                                    associated    with     securities     having
                                    speculative characteristics.  Because of the
                                    protective  features  of Senior  Loans,  the
                                    Trust and the  Adviser  believe  that  these
                                    ratings do not necessarily  reflect the true
                                    risk of loss of  principal  or interest on a
                                    Senior  Loan.   For  example,   the  Adviser
                                    believes that Senior Loans tend to have more
                                    favorable loss recovery rates as compared to
                                    most other types of below  investment  grade
                                    debt obligations.  Accordingly,  the Adviser
                                    generally does not take ratings into account
                                    when  determining  whether  to  invest  in a
                                    Senior Loan and, in any event, does not view
                                    ratings   as  a   determinative   factor  in
                                    investment decisions. As a result, the Trust
                                    is more  dependent on the  Adviser's  credit
                                    analysis abilities.

NO SALES CHARGE.                    The Shares  will be sold during the initial

                                    to  the  Underwriters  in  connection  with
                                    sales of the Shares in this  offering.  See
                                    "Underwriting."

LISTING AND SYMBOL..................The Trust has  applied  for  listing on the
                                    New  York  Stock  Exchange  of  its  Shares
                                    under the symbol "EVF."

LEVERAGE............................The  Trust  expects  to  utilize  financial
                                    leverage through borrowings,  including the
                                    issuance   of  debt   securities,   or  the
                                    issuance  of  preferred  shares or  through
                                    other   transactions,   such   as   reverse
                                    repurchase   agreements,   which  have  the
                                    effect  of  financial  leverage.  The Trust
                                    intends to utilize  financial  leverage  in
                                    an  amount  up  to 33  1/3%  of  its  total
                                    assets   (including  the  amount   obtained
                                    through  leverage).   The  Trust  generally
                                    will   not    utilize    leverage   if   it
                                    anticipates  that  it  would  result  in  a
                                    lower  return to  Shareholders  over  time.
                                    Use  of  financial   leverage   creates  an
                                    opportunity   for   increased   income  for
                                    Shareholders   but,   at  the  same   time,
                                    creates special risks,  and there can be no
                                    assurance  that a leveraging  strategy will
                                    be  successful  during  any period in which
                                    it is employed.  Because leverage  achieved
                                    through  borrowings is expected to be based
                                    on a floating  rate of interest  similar to
                                    the rate on  Senior  Loans  in the  Trust's
                                    portfolio,   the  Adviser   believes   that
                                    market  interest rate  fluctuations  should
                                    not adversely  affect returns on the Senior
                                    Loans  obtained  with the  proceeds of such
                                    borrowings.   See  "Investment   Objective,
                                    Policies and Risks - Use of Leverage."

                                    August  31,  1998 with  respect to the Eaton
                                    Vance Prime Rate Reserves  Fund, and for the
                                    three-year period ended August 31, 1998 with
                                    respect   to   the   EV    Classic    Senior
                                    Floating-Rate   Fund,  each  such  Fund  was
                                    awarded  five  stars  by  Morningstar,  Inc.
                                    Morningstar is an  independent  evaluator of
                                    public  investment  companies  and publishes
                                    "risk-adjusted ratings" on various groups of
                                    investment  companies.  The Morningstar Risk
                                    Adjusted   Rating  System   measures  return
                                    performance  and risk. The Eaton Vance Prime
                                    Rate Reserves Fund and the EV Classic Senior
                                    Floating-Rate  Fund  are in the  Morningstar
                                    Taxable Bond Fund  category,  which includes
                                    1484 (for such  three year  period)  and 912
                                    (for such five year period) other investment
                                    companies. A fund receives five stars if its
                                    risk-adjusted  performance is in the top 10%
                                    of its rating category.  Various  investment
                                    policies and restrictions of the Eaton Vance
                                    Prime Rate  Reserves Fund and the EV Classic
                                    Senior  Floating Rate Fund differ from those
                                    of the Trust. The investment  performance of
                                    such   funds  and  that  of  the  Trust  are
                                    expected to differ. Past performance of such
                                    funds is not  necessarily  indicative of the
                                    Trust's performance.  See "Management of the
                                    Trust."

SHAREHOLDER SERVICING AGENT.........___________________  has been  retained  by
                                    the    Administrator    to   act   as   the
                                    Shareholder  Servicing  Agent of the Trust.
                                    See    "Shareholder     Servicing    Agent,
                                    Custodian and Transfer Agent."

DISTRIBUTIONS.......................The Trust's  policy will be to make monthly
                                    distributions     to     Shareholders    of
                                    substantially  all net investment income of
                                    the Trust.  Distributions  to  Shareholders
                                    cannot be  assured,  and the amount of each
                                    monthly   distribution   will   vary.   The
                                    initial  distribution  to  Shareholders  is
                                    expected to be paid  approximately  60 days
                                    after  the  completion  of  this  offering.

DIVIDEND                            The  Trust  has
REINVESTMENT   PLAN..........       established  a  Dividend  Reinvestment  Plan
                                    (the "Plan").  Under the Plan,  all dividend
                                    and  capital  gain   distributions  will  be
                                    automatically   reinvested   in   additional
                                    Shares either  purchased in the open market,
                                    or  issued by the  Trust if the  Shares  are
                                    trading at or above  their net asset  value,
                                    in either case unless a  Shareholder  elects
                                    to receive cash.  Shareholders who intend to
                                    hold  their  Shares   through  a  broker  or
                                    nominee   should   contact  such  broker  or
                                    nominee to determine whether or how they may
                                    participate   in  the  Plan.  See  "Dividend
                                    Reinvestment Plan."

CLOSED END STRUCTURE................Closed-end   funds  differ  from   open-end
                                    management  investment  companies (commonly
                                    referred  to  as  mutual   funds)  in  that
                                    closed-end   funds   generally  list  their
                                    shares   for   trading   on  a   securities
                                    exchange  and do not redeem their shares at
                                    the   option   of   the   shareholder.   By
                                    comparison,  mutual funds issue  securities
                                    redeemable   at  net  asset  value  at  the
                                    option  of the  shareholder  and  typically
                                    engage in a  continuous  offering  of their
                                    shares.   Mutual   funds  are   subject  to
                                    continuous  asset  in-flows  and  out-flows
                                    that can complicate  portfolio  management,
                                    whereas   closed-end  funds  generally  can
                                    stay  more  fully  invested  in  securities
                                    consistent   with  the  closed-end   fund's
                                    investment   objective  and  policies.   In
                                    addition,  in comparison to open-end funds,
                                    closed-end  funds have greater  flexibility

                                    and in the  ability to make  certain  types
                                    of  investments,  such  as  investments  in
                                    illiquid  securities  such as Senior Loans.
                                    However,   shares   of   closed-end   funds
                                    frequently  trade at a discount  from their
                                    net  asset  value.  In  recognition  of the
                                    possibility  that the Shares might trade at
                                    a discount  to net asset value and that any
                                    such  discount  may not be in the  interest
                                    of Shareholders,  the Board of Trustees, in
                                    consultation with the  Administrator,  from
                                    time to time may  review  possible  actions
                                    to reduce any such discount,  including but
                                    not   limited   to   the   possibility   of
                                    implementing   a   "managed   distribution"
                                    policy,   which  would   entail   quarterly
                                    payments of  dividends  in an amount  equal
                                    to  a  pre-established  percentage  of  the
                                    Trust net  asset  value.  The  Board  might
                                    also  consider open market  repurchases  or
                                    tender  offers  for  Shares  at  net  asset
                                    value.  There can be no assurance  that the
                                    Board of Trustees  will decide to undertake
                                    any  of   these   actions   or   that,   if
                                    undertaken,  such  actions  would result in
                                    the Shares  trading at a price  equal to or
                                    close to net  asset  value per  Share.  The
                                    Board of Trustees  might also  consider the
                                    conversion  of  the  Trust  to an  open-end
                                    mutual   fund.   The   Board  of   Trustees
                                    believes,   however,  that  the  closed-end
                                    structure is  desirable,  given the Trust's
                                    investment    objective    and    policies.
                                    Investors  should assume,  therefore,  that
                                    it is  unlikely  that the Board of Trustees
                                    would  vote  to  convert  the  Trust  to an
                                    open-end    investment     company.     See
                                    "Description of Capital Structure."

SPECIAL RISK   
CONSIDERATIONS.........             NO   OPERATING   HISTORY.  The   Trust   is 
                                    a   closed-end investment   company   with  
                                    no  history  of operations  and is  designed
                                    for  long-term investors and not as a 
                                    trading vehicle.

                                    SENIOR LOAN  MARKET.  Senior  Loans in which
                                    the Trust will  invest may not be rated by a
                                    nationally  recognized   statistical  rating
                                    organization,  will not be  registered  with
                                    the SEC or any state  securities  commission
                                    and  generally  will  not be  listed  on any
                                    national securities exchange. Therefore, the
                                    amount of public information available about
                                    Senior Loans will generally be limited,  and
                                    the   performance   of  the  Trust  is  more
                                    dependent on the analytical abilities of the
                                    Adviser  than  would  be  the  case  for  an
                                    investment company that invests primarily in
                                    more    widely    rated,    registered    or
                                    exchange-listed  securities.  In  evaluating
                                    the   creditworthiness  of  borrowers,   the
                                    Adviser will consider, and may rely in part,
                                    on analyses  performed by others.  Moreover,
                                    because   Senior   Loans  are   subject   to
                                    contractual  restrictions they are illiquid,
                                    which may  impair  the  Trust's  ability  to
                                    realize  the full value of its assets in the
                                    event   of  a   voluntary   or   involuntary
                                    liquidation of such assets.

                                    CREDIT RISK.  Senior Loans,  like other debt
                                    obligations,  are  subject  to the  risk  of
                                    non-payment   of   scheduled   interest   or
                                    principal.  Such non-payment would result in
                                    a  reduction  of  income  to  the  Trust,  a
                                    reduction  in the value of the  Senior  Loan
                                    experiencing  non-payment  and  a  potential
                                    decrease  in  the  net  asset  value  of the
                                    Trust.  Although  Senior  Loans in which the
                                    Trust  will   invest   will  be  secured  by
                                    specific   collateral,   there   can  be  no
                                    assurance    that    liquidation   of   such
                                    collateral   would  satisfy  the  Borrower's
                                    obligation  in the event of  default or that
                                    such collateral could be readily liquidated.
                                    Most  Trust  investments  will  be of  below
                                    investment  grade  quality  which  typically
                                    have   speculative   characteristics,    and
                                    companies   obligated   by  such   debt  are
                                    generally  more  vulnerable  in an  economic
                                    downturn.  In the event of  bankruptcy  of a

                                    Borrower,  the Trust could experience delays
                                    or  limitations  with respect to its ability
                                    to realize the  benefits  of any  collateral
                                    securing a Senior  Loan.  In  addition,  the
                                    Trust may purchase interests in Senior Loans
                                    from  financial  intermediaries  whereby the
                                    Trust  depends  on  the   intermediary   for
                                    payment of  principal  and  interest  on the
                                    Senior Loan. The financial soundness of such
                                    intermediaries  may,  therefore,   adversely
                                    affect the Trust. See "Investment Objective,
                                    Policies and Risks."

                                    INTEREST  RATE  FLUCTUATIONS.  When interest
                                    rates  decline,  the  value  of a  portfolio
                                    invested in  fixed-rate  obligations  can be
                                    expected to rise. Conversely,  when interest
                                    rates   rise,   the  value  of  a  portfolio
                                    invested in  fixed-rate  obligations  can be
                                    expected  to decline.  Although  the Trust's
                                    net  asset  value  will  vary,  the  Trust's
                                    management  expects  the  Trust's  policy of
                                    acquiring   primarily  interests  in  Senior
                                    Loans to minimize  fluctuations in net asset
                                    value as a result  of  changes  in  interest
                                    rates. However, because floating or variable
                                    rates   on   Senior    Loans    only   reset
                                    periodically, changes in prevailing interest
                                    rates  can  be   expected   to  cause   some
                                    fluctuation  in the Trust's net asset value.
                                    Similarly, a sudden and significant increase
                                    in  market  interest  rates,   may  cause  a
                                    decline  in the  Trust's  net  asset  value.
                                    Moreover,  not more  than  10% of the  total
                                    assets  of the  Trust  may be  comprised  of
                                    income   securities   with  fixed  rates  of
                                    interest  which  may lose  value  in  direct
                                    response to market interest rate increases.

                                    EFFECTS OF LEVERAGE.  The use of leverage by
                                    the  Trust   creates  an   opportunity   for
                                    increased net income, but, at the same time,
                                    creates  special  risks.  There  can  be  no
                                    assurance that a leveraging strategy will be
                                    successful  during any period in which it is
                                    employed.   The  Trust  intends  to  utilize
                                    leverage  to provide  the  holders of Shares
                                    with a potentially  higher return.  Leverage
                                    creates   risks   for   holders   of  Shares
                                    including   the    likelihood   of   greater
                                    volatility  of net asset  value  and  market
                                    price  of  the  Shares  and  the  risk  that
                                    fluctuations in interest rates on borrowings
                                    and  debt or in the  dividend  rates  on any
                                    preferred  shares  may  affect the return to
                                    Shareholders.   To  the  extent  the  income
                                    derived from securities purchased with funds
                                    received from  leverage  exceeds the cost of
                                    leverage, the Trust's return will be greater
                                    than  if   leverage   had  not  been   used.
                                    Conversely,   if   the   income   from   the
                                    securities  purchased with such funds is not
                                    sufficient  to cover  the cost of  leverage,
                                    the return to the Trust will be less than if
                                    leverage  had not been used,  and  therefore
                                    the amount  available  for  distribution  to
                                    Shareholders    as   dividends   and   other
                                    distributions will be reduced. In the latter
                                    case,  Eaton Vance in its best  judgment may
                                    nevertheless   determine   to  maintain  the
                                    Trust's leveraged  position if it deems such
                                    action   to   be   appropriate   under   the
                                    circumstances.  During  periods in which the
                                    Trust is utilizing financial  leverage,  the
                                    investment   management  and  administration
                                    fee,  which is payable  to Eaton  Vance as a
                                    percentage of the Trust's total assets, will
                                    be higher  than if the Trust did not utilize
                                    a leveraged capital structure. Certain types
                                    of borrowings by the Trust may result in the
                                    Trust being  subject to  covenants in credit
                                    agreements,   including  those  relating  to
                                    asset  coverage  and  portfolio  composition
                                    requirements.  The Trust may be  subject  to
                                    certain  restrictions on investments imposed
                                    by   guidelines   of  one  or  more   rating
                                    agencies,  which may issue  ratings  for the

                                    debt  securities or preferred  shares issued
                                    by the Trust.  These  guidelines  may impose
                                    asset  coverage  or  portfolio   composition
                                    requirements  that are more  stringent  than
                                    those imposed by the Investment  Company Act
                                    of 1940, as amended (the "Investment Company
                                    Act").  It is  not  anticipated  that  these
                                    covenants  or  guidelines  will impede Eaton
                                    Vance in managing  the Fund's  portfolio  in
                                    accordance   with  the  Trust's   investment
                                    objectives and policies.  As discussed under
                                    "Management  of the  Trust," the fee paid to
                                    Eaton Vance will be  calculated on the basis
                                    of the  Trust's  assets  including  proceeds
                                    from   borrowings   for   leverage  and  the
                                    issuance   of    preferred    shares.    See
                                    "Investment Objective,  Policies and Risks -

                                    SPECIAL INVESTMENT PRACTICES.  The Trust may
                                    use  various   investment   practices   that
                                    involve  special  considerations   including
                                    lending   its   portfolio   securities   and
                                    entering   into   repurchase   and   reverse
                                    repurchase  agreements.   In  addition,  the
                                    Trust  has  the   authority   to  engage  in
                                    interest  rate and  other  hedging  and risk
                                    management transactions. For a discussion of
                                    these practices,  see "Investment Objective,
                                    Policies  and  Risks  -  Special  Investment
                                    Practices."

                                    INVESTMENT IN NON-U.S.  ISSUERS.  The Trust
                                    may  invest  in  Senior   Loans  and  other
                                    income  producing   securities  of  issuers
                                    that are  organized or located in countries
                                    other  than  the  United  States,  provided
                                    that such  investments  are  denominated in
                                    U.S.  dollars  and  provide for the payment
                                    of interest  and  repayment of principal in
                                    U.S.   dollars.   Investment   in  non-U.S.
                                    issuers involves  special risks,  including
                                    that  non-U.S.  issuers  may be  subject to
                                    less  rigorous   accounting  and  reporting
                                    requirements   than  U.S.   issuers,   less
                                    rigorous      regulatory      requirements,
                                    differing  legal  systems and laws relating
                                    to   creditors'   rights,   the   potential
                                    inability to enforce  legal  judgments  and
                                    the  potential  for  political,  social and
                                    economic adversity.

                                    MARKET  PRICE  OF  SHARES.   The  shares  of
                                    closed-end  investment companies often trade
                                    at a discount  from  their net asset  value,
                                    and the Trust's Shares may likewise trade at
                                    a discount from net asset value. The trading
                                    price of the Trust's Shares may be less than
                                    the public offering price.  This risk may be
                                    greater for  investors  selling their Shares
                                    in   a   relatively   short   period   after
                                    completion of the public offering.

                                    NON-DIVERSIFICATION.     The    Trust    has
                                    registered as a "non-diversified" investment
                                    company  so that  it will be able to  invest
                                    more than 5% of the  value of its  assets in
                                    the   obligations   of  any  single  issuer,
                                    although it has no current  intention  to do
                                    so. The Trust will not invest  more than 10%
                                    of  its  assets  in  securities   (including
                                    interests  in Senior  Loans)  of any  single
                                    Borrower.  To the extent the Trust invests a
                                    relatively  high percentage of its assets in
                                    obligations  of a limited number of issuers,
                                    the  Trust  may be more  susceptible  than a
                                    more widely  diversified  investment company
                                    to any single corporate, economic, political
                                    or regulatory occurrence.

                                    ANTI-TAKEOVER   PROVISIONS.   The   Trust's
                                    Declaration  of Trust  includes  provisions
                                    that could have the effect of limiting  the

                                  THE TRUST

      Eaton  Vance  Senior  Income  Trust (the  "Trust")  is a newly  organized,
non-diversified, closed-end management investment company which was organized as
a  Massachusetts  business  trust on  September  23,  1998 and has no  operating
history.  The Trust's principal office is located at 24 Federal Street,  Boston,
MA 02110 and its telephone number is 1-800-225-6265.

      This  Prospectus  relates to the  initial  public  offering of the Trust's
shares of beneficial interest, $.01 par value (the "Shares"). The Shares will be
sold during the initial public  offering  without any sales load or underwriting
discounts  payable  by  investors  or the Trust.  Eaton  Vance  Management  (the
"Adviser" or "Eaton  Vance") or an affiliate (not the Trust) from its own assets
will pay a commission to the Underwriters in connection with sales of the Shares
in this offering. See "Underwriting."

                               USE OF PROCEEDS

      The net proceeds of this offering,  before deduction of offering expenses,
estimated to be $ (or $ assuming  exercise of the  Underwriters'  over-allotment
option in full),  will be invested  in  accordance  with the Trust's  investment
objectives and policies as soon as  practicable,  but in no event,  under normal
market  conditions,  later than three months after the receipt thereof.  Pending
such investment,  the proceeds may be invested in high-quality,  short-term debt
securities.  Eaton  Vance has  agreed  to pay all  organizational  and  offering
expenses of the Trust that exceed $.02 per share.

                   INVESTMENT OBJECTIVE, POLICIES AND RISKS

      The Trust's  investment  objective is to provide  Shareholders with a high
level of current income,  consistent with preservation of capital,  by investing
primarily in senior secured floating rate loans ("Senior Loans").  The borrowers
of such loans will be  corporations,  partnerships  and other business  entities
("Borrowers") which operate in a variety of industries and geographical regions.
The  Trust  provides  individual  investors  with  access  to a market  normally
accessible only to financial  institutions and larger corporate or institutional
investors.

GENERAL COMPOSITION OF THE TRUST

      In normal market conditions, at least 80% of the Trust's total assets will
be invested in interests in Senior Loans  (either as an original  Lender or as a
purchaser of an Assignment or Participation,  each as defined below) of domestic
or foreign  borrowers (so long as foreign loans are U.S. dollar  denominated and
payments of interest and repayments of principal are required to be made in U.S.
dollars).  The  Trust  may  invest  up to 20% of its  total  assets  in (i) loan
interests  which are not secured by any, or that have a lower than senior  claim
on,  collateral,  (ii) other income producing  securities such as investment and
non-investment  grade  corporate debt  securities  and U.S.  government and U.S.
dollar denominated  foreign government or supranational debt securities (subject
to the limit that no more than 10% of the Trust's  total  assets may be invested
in  securities  with a fixed rate of  interest),  and (iii)  warrants and equity
securities  issued by a  Borrower  or its  affiliates  as part of a  package  of
investments in the Borrower or its  affiliates.  If the Adviser  determines that
market conditions  temporarily warrant a defensive  investment policy, the Trust
may invest up to 100% of its assets in cash and high  quality,  short-term  debt
securities.

      Based  upon available  market data, the Adviser  believes that the overall
market for U.S. fixed income securities,  including U.S. government  securities,
investment and non-investment grade corporate bonds, mortgage-related securities
and  commercial  paper,  totaled  outstanding  principal of  approximately  $8.4
trillion at the end of 1997,  and that Senior  Loans  represented  approximately
$375  billion (or 4.5%) of that total  amount.  Senior  Loans in which the Trust
will invest generally pay interest at rates which are redetermined  periodically
by reference to a base lending  rate,  plus a premium.  These base lending rates
generally  are the prime rate offered by one or more major  United  States banks
(the  "Prime  Rate"),  the  London  Inter-Bank   Offered  Rate  ("LIBOR"),   the
certificate  of  deposit  ("CD")  rate  or  other  base  lending  rates  used by
commercial lenders.  The following table is intended to provide investors with a

comparison of short-term  money market rates, a  representative  base commercial
lending  rate,  and a  representative  indicator  of the premium  over such base
lending  rate for Senior  Loans.  This  comparison  should not be  considered  a
representation  of future money market rates,  spreads of Senior Loans over base
reference  rates  nor  what  an  investment  in the  Trust  may  earn or what an
investor's yield or total return may be in the future.

      It is anticipated that the proceeds of the Senior Loans in which the Trust
will acquire  interests  primarily  will be used to finance  leveraged  buyouts,
recapitalizations,  mergers,  acquisitions,  stock repurchases, and, to a lesser
extent,  to  finance  internal  growth  and  for  other  corporate  purposes  of
borrowers.  Senior Loans have the most senior  position in a Borrower's  capital
structure,  although  some  Senior  Loans may hold an equal  ranking  with other
senior  securities  of the  Borrower.  The capital  structure  of a borrower may
include Senior Loans, senior and junior  subordinated debt,  preferred stock and
common stock issued by the borrower,  typically in descending order of seniority
with  respect to claims on the  borrower's  assets.  Senior Loans are secured by
specific collateral.

      In  order to borrow  money  pursuant  to Senior  Loans,  a  Borrower  will
frequently,  for the term of the Senior Loan, pledge  collateral,  including but
not limited to, (i) working  capital  assets,  such as accounts  receivable  and
inventory;  (ii) tangible  fixed assets,  such as real  property,  buildings and
equipment;  (iii) intangible  assets,  such as trademarks and patent rights (but
excluding  goodwill);  and  (iv)  security  interests  in  shares  of  stock  or
subsidiaries  or  affiliates.  In the case of Senior  Loans  made to  non-public
companies,  the company's  shareholders or owners may provide  collateral in the
form of secured guarantees and/or security interests in assets that they own. In
certain instances, a Senior Loan may be secured only by stock in the Borrower or
its  subsidiaries.  Collateral  may  consist  of assets  that may not be readily
liquidated,  and there is no assurance that the liquidation of such assets would
satisfy fully a borrower's  obligations  under a Senior Loan. The Trust will not
invest in Senior Loans unless, at the time of investment, the Adviser determines
that the value of the  collateral  equals or exceeds the  aggregate  outstanding
principal amount of the Senior Loans.

      The Trust is not subject to any restrictions  with respect to the maturity
of Senior Loans held in its portfolio. Senior Loans typically have a stated term
of between five to nine years,  and have rates of interest  which  typically are
redetermined either daily, monthly, quarterly or semi-annually.  Longer interest
rate redetermination  periods generally increase fluctuations in the Trust's net
asset value as a result of changes in interest  rates.  The Senior  Loans in the
Trust's  portfolio  will have a  dollar-weighted  average  period until the next
interest rate  adjustment  of  approximately  90 days or less.  As a result,  as
short-term  interest  rates  increase,  interest  payable  to the Trust from its
investments in Senior Loans should  increase,  and as short-term  interest rates
decrease,  interest  payable to the Trust from its  investments  in Senior Loans
should decrease.  The Trust may utilize certain  investment  practices to, among


                                       9
<PAGE>

other things,  shorten the effective  interest  rate  redetermination  period of
Senior Loans in its  portfolio.  In the  experience of the Adviser over the last
decade,  because of prepayments the average life of Senior Loans has been two to
three years.

      Borrowers  may have  outstanding  debt  obligations  that are rated  below
investment grade by a nationally  recognized  statistical  rating  organization.
More recently, such organizations have begun rating Senior Loans and many Senior
Loans have been assigned a rating below investment  grade. Debt securities rated
below investment  grade are viewed by the rating agencies as having  speculative
characteristics  and are commonly  known as "junk bonds." A  description  of the
ratings  of  corporate  bonds is  included  as  Appendix A to the  Statement  of
Additional Information.  Because of the protective features of Senior Loans, the
Trust and the Adviser believe that these ratings do not necessarily  reflect the
true risk of loss of principal or interest on a Senior  Loan.  For example,  the
Adviser  believes  that Senior Loans tend to have more  favorable  loss recovery
rates  as  compared  to  most  other  types  of  below   investment  grade  debt
obligations.  Accordingly,  the Adviser  generally  does not take  ratings  into
account when  determining  whether to invest in a Senior Loan and, in any event,
does not view ratings as a determinative  factor in investment  decisions.  As a
result, the Trust is more dependant on the Adviser's credit analysis abilities.

      A lender may have certain obligations pursuant to a loan agreement,  which
may include the obligation to make  additional  loans in certain  circumstances.
The  Trust  generally  will  reserve  against  such  contingent  obligations  by
segregating a sufficient  amount of cash,  liquid  securities  and liquid Senior
Loans, subject to the Trust's borrowing limitations. The Trust will not purchase
interests  in  Senior  Loans  that  would  require  the  Trust  to make any such
additional  loans if such  additional  loan  commitments in the aggregate  would
exceed 20% of the Trust's  total assets or would cause the Trust to fail to meet
its diversification requirements.

      The Trust may purchase and retain in its portfolio a Senior Loan where the
Borrower has experienced, or may be perceived to be likely to experience, credit
problems,   including   involvement  in  or  recent  emergence  from  bankruptcy
reorganization   proceedings  or  other  forms  of  debt   restructuring.   Such
investments  may provide  opportunities  for enhanced  income as well as capital
appreciation.  At times, in connection with the  restructuring  of a Senior Loan
either  outside  of  bankruptcy  court or in the  context  of  bankruptcy  court
proceedings,  the Trust may determine or be required to accept equity securities
or junior debt securities in exchange for all or a portion of a Senior Loan.

      The Trust also may invest up to 5% of its total assets in structured notes
with rates of return  determined by reference to the total rate of return on one
or more loans  referenced  in such notes.  The rate of return on the  structured
note may be  determined  by applying a multiplier to the rate of total return on
the referenced  loan or loans.  Application of a multiplier is comparable to the
use of financial  leverage,  a  speculative  technique.  Leverage  magnifies the
potential for gain and the risk of loss; as a result, a relatively small decline
in the value of a referenced note could result in a relatively large loss in the
value of a structured note. Structured notes will be treated as Senior Loans for
purposes of the Trust's policy of normally  investing at least 80% of its assets
in Senior Loans.

CERTAIN CHARACTERISTICS OF SENIOR LOANS

      A Senior Loan is typically originated, negotiated and structured by a U.S.
or  foreign  commercial  bank,  insurance  company,  finance  company  or  other
financial  institution  (the  "Agent")  for a  lending  syndicate  of  financial
institutions  ("Lenders").  The Agent  typically  administers  and  enforces the
Senior Loan on behalf of the other  Lenders in the  syndicate.  In addition,  an
institution,  typically but not always the Agent, holds any collateral on behalf
of the Lenders.

 ......Senior   Loans   include   senior   secured   floating   rate   loans  and
institutionally  traded senior secured floating rate debt obligations  issued by
an asset-backed pool, and interests therein.  Loan interests  generally take the
form of direct  interests  acquired during a primary  distribution  and may also
take the form of participation  interests in,  assignments of, or novations of a
Senior Loan acquired in secondary  markets.  Such loan interests may be acquired
from U.S. or foreign commercial banks, insurance companies, finance companies or
other  financial  institutions  who have made loans or are  members of a lending
syndicate or from other  holders of loan  interests.  The Trust may also acquire
loan  interests  under  which the Trust  derives  its rights  directly  from the
Borrower.



                                       10
<PAGE>

      The Trust may invest without limit in "Participations."  Participations by
the Trust in a Lender's  portion of a Senior Loan  typically  will result in the
Trust having a  contractual  relationship  only with such  Lender,  not with the
Borrower.  As a result,  the Trust may have the  right to  receive  payments  of
principal,  interest  and any fees to which it is entitled  only from the Lender
selling the  Participation and only upon receipt by such Lender of such payments
from the  Borrower.  In connection  with  purchasing  Participations,  the Trust
generally  will have no right to enforce  compliance  by the  Borrower  with the
terms of the loan  agreement,  nor any rights with respect to any funds acquired
by other  Lenders  through  set-off  against the  Borrower and the Trust may not
directly benefit from the collateral  supporting the Senior Loan in which it has
purchased the  Participation.  As a result, the Trust may assume the credit risk
of both the Borrower and the Lender selling the  Participation.  In the event of
the insolvency of the Lender selling a  Participation,  the Trust may be treated
as a general  creditor of such  Lender.  The selling  Lenders and other  persons
interpositioned  between  such  Lenders  and  the  Trust  with  respect  to such
Participations  will likely conduct their principal  business  activities in the
banking,  finance and financial  services  industries.  Persons  engaged in such
industries  may be more  susceptible  to, among other  things,  fluctuations  in
interest rates,  changes in the Federal Open Market Committee's monetary policy,
governmental  regulations  concerning  such  industries and  concerning  capital
raising   activities   generally  and  fluctuations  in  the  financial  markets
generally.

      The Trust may also purchase  "Assignments" from Lenders.  The purchaser of
an Assignment  typically  succeeds to all the rights and  obligations  under the
Loan  Agreement  of the  assigning  Lender and  becomes a Lender  under the Loan
Agreement  with  the  same  rights  and  obligations  as the  assigning  Lender.
Assignments  may,  however,  be arranged  through private  negotiations  between
potential  assignees and  potential  assignors,  and the rights and  obligations
acquired by the purchaser of an Assignment  may differ from, and be more limited
than, those held by the assigning Lender.

      The Trust  will only  acquire  Participations  if the Lender  selling  the
Participation,  and any other persons  interpositioned between the Trust and the
Lender,  at the time of investment has outstanding  debt or deposit  obligations
rated  investment grade (BBB or A-3 or higher by Standard & Poor's Ratings Group
("S&P") or Baa or P-3 or higher by Moody's Investors Service,  Inc.  ("Moody's")
or  comparably  rated by another  nationally  recognized  rating  agency (each a
"Rating  Agency")) or  determined  by the Adviser to be of  comparable  quality.
Similarly, the Trust will purchase an Assignment or act as a Lender with respect
to a  syndicated  Senior  Loan only where the Agent with  respect to such Senior
Loan at the time of investment has outstanding debt or deposit obligations rated
investment  grade or  determined  by the  Adviser to be of  comparable  quality.
Long-term debt rated BBB by S&P is regarded by S&P as having  adequate  capacity
to pay interest and repay principal and debt rated Baa by Moody's is regarded by
Moody's as a medium grade  obligation,  I.E., it is neither highly protected nor
poorly  secured.  Commercial  paper rated A-3 by S&P indicates that S&P believes
such  obligations  exhibit  adequate  protection  parameters  but  that  adverse
economic  conditions  or  changing  circumstances  are more  likely to lead to a
weakened  capacity  of the  obligor  to meet  its  financial  commitment  on the
obligation and issues of commercial paper rated P-3 by Moody's are considered by
Moody's  to  have  an  acceptable  ability  for  repayment  of  short-term  debt
obligations but the effect of industry  characteristics  and market compositions
may be more pronounced.

OTHER INCOME PRODUCING SECURITIES

      The Trust, with respect to 20% of its total assets, may purchase a variety
of U.S. and foreign  corporate and  government  debt  obligations  that are U.S.
dollar denominated. The Adviser may consider capital appreciation potential when
investing  in such  income  producing  debt  securities,  which may have  fixed,
variable or floating rates of interest.  These securities may include  interests
in loans from  Borrowers  that are not  secured by any,  or that have lower than
senior claim on, collateral, may include warrants and equity securities acquired
in  connection  with the  Trust's  ownership  of Senior  Loans  and may  include
subordinated  high yield corporate bonds.  The Trust will limit  acquisitions of
such securities that have a fixed rate of interest to 10% of total assets.



                                       11
<PAGE>

USE OF LEVERAGE

      The Trust expects to utilize  leverage through  borrowings,  including the
issuance of debt  securities,  or the  issuance of  preferred  shares or through
other transactions, such as reverse repurchase agreements, which have the effect
of financial leverage.  The Trust intends to utilize leverage in an amount up to
approximately  33 1/3% of its total assets  (including the amount  obtained from
leverage).  The  Trust  generally  will  not  utilize  leverage  if the  Adviser
anticipates  that it would  result  in a lower  return to  Shareholders  for any
significant  amount of time.  The Trust  also may  borrow  money as a  temporary
measure  for  extraordinary  or  emergency  purposes,  including  the payment of
dividends  and the  settlement of securities  transactions  which  otherwise may
require untimely dispositions of Trust securities.

      Leverage creates risks for holders of the Shares, including the likelihood
of greater  volatility of net asset value and market price of the Shares.  While
there is some  risk  that  fluctuations  in  interest  rates on  borrowings  and
short-term debt or in the dividend rates on any preferred  shares may affect the
return to the holders of the Shares,  the Adviser  believes  that this should be
minimized  because  borrowings and Senior Loans will ordinarily have the same or
similar floating rates of interest.  If the income from the securities purchased
with such funds is not  sufficient to cover the cost of leverage,  the return on
the Trust will be less than if leverage  had not been used,  and  therefore  the
amount  available  for  distribution  to  Shareholders  as  dividends  and other
distributions will be reduced. The Adviser in its best judgment nevertheless may
determine to maintain the Trust's leveraged  position if it deems such action to
be appropriate  under the  circumstances.  As discussed under "Management of the
Trust,"  the fee paid to the  Adviser  will be  calculated  on the  basis of the
Trust's total assets,  including  proceeds from  borrowings for leverage and the
issuance of preferred shares.

      Capital  raised  through  leverage  will be subject to  interest  costs or
dividend payments which may not exceed the income and appreciation on the assets
purchased.  The Trust,  among  other  things,  also may be  required to maintain
minimum average balances in connection with borrowings or to pay a commitment or
other  fee to  maintain  a line of  credit;  either of these  requirements  will
increase the cost of borrowing  over the stated  interest  rate. The issuance of
preferred  shares involves  offering  expenses and other costs and may limit the
Trust's  freedom to pay  dividends  on Shares or to engage in other  activities.
Borrowings and the issuance of a class of preferred  shares having priority over
the Trust's  Shares create an opportunity  for greater return per Share,  but at
the  same  time  such  leveraging  is a  speculative  technique  in that it will
increase  the  Trust's   exposure  to  capital  risk.   Unless  the  income  and
appreciation,  if any,  on  assets  acquired  with  borrowed  funds or  offering
proceeds  exceed  the  cost  of  borrowing  or  issuing  additional  classes  of
securities,  the use of leverage will diminish the investment performance of the
Trust compared with what it would have been without leverage.

      Certain  types of  borrowings  may  result in the Trust  being  subject to
covenants in credit  agreements,  including those relating to asset coverage and
portfolio  composition  requirements.  The  Trust  may  be  subject  to  certain
restrictions on investments imposed by guidelines of one or more Rating Agencies
which may issue ratings for the corporate  debt  securities or preferred  shares
issued by the Trust.  These  guidelines  may impose asset  coverage or portfolio
composition  requirements  that are more  stringent  than  those  imposed by the
Investment Company Act. It is not anticipated that these covenants or guidelines
will impede the Adviser from managing the Trust's  portfolio in accordance  with
the Trust's  investment  objectives  and  policies.  The Trust  currently  is in
preliminary  negotiations  with a commercial bank to arrange a syndicated credit
facility. The terms of any agreements relating to the credit facility, including
commitment  and  facility  fees  and  the  rate  of  interest  charged  on  such
borrowings, have not been determined and are subject to definitive agreement and
other conditions.

      Under the  Investment  Company  Act,  the Trust is not  permitted to incur
indebtedness  unless  immediately  after such  incurrence the Trust has an asset
coverage  of at least 300% of the  aggregate  outstanding  principal  balance of
indebtedness  (I.E.,  such  indebtedness  may not exceed 33 1/3% of the  Trust's
total assets). Additionally, under the Investment Company Act, the Trust may not
declare any dividend or other distribution upon any class of its capital shares,
or purchase any such capital  shares,  unless the aggregate  indebtedness of the
Trust has, at the time of the  declaration of any such dividend or  distribution
or at the time of any such  purchase,  an asset  coverage of at least 300% after
deducting the amount of such dividend,  distribution,  or purchase price, as the
case may be. Under the  Investment  Company  Act, the Trust is not  permitted to
issue  preferred  shares  unless  immediately  after such issuance the net asset


                                       12
<PAGE>

value of the Trust's  portfolio is at least 200% of the liquidation value of the
outstanding preferred shares (I.E., such liquidation value may not exceed 50% of
the Trust's total  assets).  In addition,  the Trust is not permitted to declare
any cash dividend or other  distribution  on its Shares  unless,  at the time of
such declaration, the net asset value of the Trust's portfolio (determined after
deducting the amount of such dividend or other distribution) is at least 200% of
such liquidation  value. If preferred shares are issued,  the Trust intends,  to
the extent possible, to purchase or redeem preferred shares from time to time to
maintain coverage of any preferred shares of at least 200%.

      The  Trust's  willingness  to borrow  money and issue new  securities  for
investment purposes,  and the amount the Trust will borrow or issue, will depend
on many factors,  the most  important of which are  investment  outlook,  market
conditions and interest rates.  Successful use of a leveraging  strategy depends
on the  Adviser's  ability  to  predict  correctly  interest  rates  and  market
movements,  and  there  is no  assurance  that a  leveraging  strategy  will  be
successful during any period in which it is employed.

      Assuming the  utilization  of leverage in the amount of  approximately  33
1/3% of the Trust's total assets,  and an annual  interest rate on borrowings of
6.1%  payable  on such  leverage  based on  market  rates as of the date of this
Prospectus, the annual return that the Trust's portfolio must experience (net of
expenses) in order to cover such interest  payments would be 2.03%.  The Trust's
actual  cost of  leverage  will be based on  market  rates at the time the Trust
undertakes a leveraging strategy, and such actual cost of leverage may be higher
or lower than that assumed in the previous example.

      The following  table is designed to illustrate the effect on the return to
a holder of the Trust's  Shares of leverage  in the amount of  approximately  33
1/3% of the Trust's total assets,  assuming  hypothetical  annual returns of the
Trust's  portfolio  of minus  10% to plus  10%.  As the  table  shows,  leverage
generally increases the return to shareholders when portfolio return is positive
and  greater  than  the cost of  leverage  and  decreases  the  return  when the
portfolio  return is  negative  or less than the cost of  leverage.  The figures
appearing  in the table are  hypothetical  and actual  returns may be greater or
less than those appearing in the table.

</TABLE>

      Until the Trust borrows or issues preferred shares, the Shares will not be
leveraged,  and  the  risks  and  special  considerations  related  to  leverage
described  in this  Prospectus  will not apply.  Such  leveraging  of the Shares
cannot be achieved  until the proceeds  resulting  from the use of leverage have
been invested in accordance with the Trust's investment objective and policies.

ADDITIONAL RISK CONSIDERATIONS

      INTEREST RATE RISK. When interest rates decline,  the value of a portfolio
invested in fixed-rate  obligations  can be expected to rise.  Conversely,  when
interest rates rise, the value of a portfolio invested in fixed-rate obligations
can be expected to decline.  Although the Trust's net asset value will vary, the
Trust's management expects the Trust's policy of acquiring  primarily  interests
in Senior  Loans to  minimize  fluctuations  in net  asset  value as a result of
changes in interest rates. However, because floating or variable rates on Senior
Loans  only reset  periodically,  changes in  prevailing  interest  rates can be
expected to cause some fluctuation in the Trust's net asset value.  Similarly, a
sudden and significant increase in market interest rates, may cause a decline in
the Trust's net asset value.

      CREDIT RISK.  Senior Loans,  like other  corporate debt  obligations,  are
subject to the risk of  non-payment  of scheduled  interest or  principal.  Such
non-payment  would result in a reduction of income to the Trust,  a reduction in
the value of the Senior Loan experiencing  non-payment and a potential  decrease
in the net asset value of the Trust. Although, with respect to Senior Loans, the
Trust  generally will invest only in Senior Loans that the Adviser  believes are
secured  by  specific  collateral  the  value of which  equals  or  exceeds  the
principal amount of the Senior Loan at the time of initial investment, there can
be no assurance that the  liquidation of any such  collateral  would satisfy the
Borrower's  obligation  in the event of  non-payment  of  scheduled  interest or


                                       13
<PAGE>

principal payments, or that such collateral could be readily liquidated.  In the
event of  bankruptcy  of a  Borrower,  the  Trust  could  experience  delays  or
limitations  with  respect  to  its  ability  to  realize  the  benefits  of the
collateral  securing  a  Senior  Loan.  To the  extent  that a  Senior  Loan  is
collateralized by stock in the Borrower or its subsidiaries, such stock may lose
all or  substantially  all of  its  value  in the  event  of  bankruptcy  of the
Borrower.  The Agent generally is responsible  for determining  that the Lenders
have  obtained a perfected  security  interest in the  collateral  securing  the
Senior Loan.  Some Senior Loans in which the Trust may invest are subject to the
risk that a court,  pursuant to  fraudulent  conveyance  or other  similar laws,
could subordinate such Senior Loans to presently existing or future indebtedness
of the Borrower or take other action detrimental to the holders of Senior Loans,
such as the Trust,  including,  under certain  circumstances,  invalidating such
Senior Loans.

      Senior  Loans in which  the  Trust  will  invest  often are not rated by a
nationally  recognized  statistical rating organization,  will not be registered
with the SEC or any state  securities  commission  and will not be listed on any
national securities  exchange.  Although the Trust will generally have access to
financial and other information made available to the Lenders in connection with
Senior Loans, the amount of public information  available with respect to Senior
Loans will generally be less extensive than that available for rated, registered
or exchange listed  securities.  Borrowers may have outstanding debt obligations
that are rated below  investment  grade by a nationally  recognized  statistical
rating organization.  More recently, such organizations have begun rating Senior
Loans and many Senior Loans have been assigned a rating below investment  grade.
Debt securities  rated below  investment grade are viewed by the rating agencies
as having  speculative  characteristics  and are commonly known as "junk bonds."
Because of the  protective  features of Senior Loans,  the Trust and the Adviser
believe that these ratings do not  necessarily  reflect the true risk of loss of
principal or interest on a Senior Loan. For example,  the Adviser  believes that
Senior Loans tend to have more favorable loss recovery rates as compared to most
other types of defaulted debt  obligations.  Accordingly,  the Adviser generally
does not take  ratings  into  account  when  determining  whether to invest in a
Senior Loan and, in any event,  does not view ratings as a determinative  factor
in  investment  decisions.  As a  result,  the  Trust is more  dependent  on the
Adviser's credit analysis abilities.

      The Trust may invest up to 20% of its total assets in loans from borrowers
that  are not  secured  by any,  or that  have  lower  than a senior  claim  on,
collateral,  in warrants and equity  securities  acquired in connection with the
Trust's ownership of Senior Loans, and, with respect to up to 10% of the Trust's
total  assets,  may invest in fixed  interest rate debt  securities.  Securities
rated below investment grade are, commonly referred to as "junk bonds."

      Lower  quality  debt  securities  are  subject to the risk of an  issuer's
inability to meet  principal and interest  payments on the  obligations  (credit
risk)  and may  also be  subject  to price  volatility  due to such  factors  as
interest rate  sensitivity,  market  perception of the  creditworthiness  of the
issuer and general market liquidity (market risk). The prices of lower-rated and
comparable unrated securities are also more likely to react to real or perceived
developments  affecting  market and credit risk than are prices of  higher-rated
securities,  which react primarily to movements in the general level of interest
rates. A substantial portion of such bonds may be lower-rated  securities issued
in connection with mergers, acquisitions,  leveraged buy-outs, recapitalizations
and other highly leveraged transactions,  which pose a higher risk of default or
bankruptcy of the issuer than other fixed-income  securities particularly during
periods of  deteriorating  economic  conditions  and  contraction  in the credit
markets.  The  investments  in  the  Trust's  portfolio  will  have  speculative
characteristics.

      FOREIGN  SECURITIES.  Although  the Trust will only invest in U.S.  dollar
denominated  income  securities,  investment in  securities of non-U.S.  issuers
involves special risks,  including that non-U.S.  issuers may be subject to less
rigorous accounting and reporting  requirements than U.S. issuers, less rigorous
regulatory requirements, differing legal systems and laws relating to creditors'
rights, the potential inability to enforce legal judgments and the potential for
political,  social  and  economic  adversity.  The  willingness  and  ability of
sovereign issuers to pay principal and interest on government securities depends
on various  economic  factors,  including  among others the issuer's  balance of
payments,  overall  debt  level,  and cash flow  considerations  related  to the
availability of tax or other revenues to satisfy the issuer's  obligations.  The
securities  of some foreign  issuers are less liquid and at times more  volatile
than securities of comparable U.S. issuers.  Foreign  settlement  procedures and
trade  regulations  may involve  certain  risks (such as delay in the payment or
delivery of  securities  or in the  recovery of assets held abroad) and expenses
not present in the settlement of domestic  investments.  Investments may include


                                       14
<PAGE>

securities issued by the governments of  lesser-developed  countries,  which are
sometimes  referred to as  "emerging  markets."  There may be a  possibility  of
nationalization  or  expropriation  of assets,  imposition of currency  exchange
controls,  confiscatory  taxation,  political  or financial  instability,  armed
conflict  and  diplomatic  developments  which could  affect the values of a the
Trust's investments in certain foreign countries.

      LIQUIDITY  RISK.  Senior  Loans,  at present,  are  generally  not readily
marketable  and subject to  restrictions  on resale.  Interests  in Senior Loans
generally  are not  listed on any  national  securities  exchange  or  automated
quotation  system and no active  trading market may exist for many of the Senior
Loans in which the Trust will invest.  To the extent that a secondary market may
exist for certain of the Senior  Loans in which the Trust  invests,  such market
may be subject to irregular trading activity,  wide bid/ask spreads and extended
trade  settlement  periods.  Senior Loans are thus  relatively  illiquid,  which
illiquidity  may impair  the  Trust's  ability to realize  the full value of its
assets in the event of a voluntary or  involuntary  liquidation  of such assets.
The Trust has no limitation on the amount of its assets which may be invested in
securities  which are not readily  marketable or are subject to  restrictions on
resale.  The  substantial  portion of the Trust's assets invested in Senior Loan
interests may restrict the ability of the Trust to dispose of its investments in
a timely fashion and at a fair price,  and could result in capital losses to the
Trust  and  holders  of  Shares.  The  risks  associated  with  illiquidity  are
particularly acute in situations where the Trust's operations require cash, such
as when the Trust tenders for its Shares,  and may result in the Trust borrowing
to meet short-term cash requirements.

      REGULATORY  CHANGES.  To the extent that  legislation  or state or federal
regulators  that  regulate  certain  financial  institutions  impose  additional
requirements or restrictions with respect to the ability of such institutions to
make loans,  particularly in connection with highly leveraged transactions,  the
availability  of  Senior  Loan  interests  for  investment  by the  Trust may be
adversely  affected.  Further,  such legislation or regulation could depress the
market value of Senior Loans held by the Trust.

      CLOSED-END  FUNDS.  The Trust is a closed-end  investment  company with no
history of operations and is designed primarily for long-term  investors and not
as a trading vehicle. The shares of closed-end  investment companies often trade
at a discount  from their net asset value,  and the Trust's  Shares may likewise
trade at a discount  from net asset  value.  The  trading  price of the  Trust's
Shares may be less than the initial public  offering  price,  creating a risk of
loss for investors purchasing in the initial public offering of the Shares. This
market price risk may be greater for  investors  who sell their Shares  within a
relatively short period after completion of this offering.

      NON-DIVERSIFICATION.  The  Trust  has  registered  as a  "non-diversified"
investment company so that, subject to its investment  restrictions,  it will be
able to invest more than 5% of the value of its assets in the obligations of any
single  issuer,  including  Senior Loans of a single  Borrower or single Lender,
although  it has no current  intention  to do so. The Trust will not invest more
than 10% of the value of its assets in securities (including interests in Senior
Loans) of any single Borrower. Moreover, the Trust may invest more than 10% (but
not more than 25%) of its total  assets in Senior Loan  interests  for which the
same intermediate  participant is interposed between the Trust and the Borrower.
To the extent the Trust  invests a relatively  high  percentage of its assets in
obligations of a limited number of issuers,  the Trust will be more  susceptible
than a more  widely  diversified  investment  company to any  single  corporate,
economic, political or regulatory occurrence.

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

      In  addition,  it is possible  that the markets for Senior Loans and other
securities in which the Trust invests may be detrimentally  affected by computer
failures  throughout the financial  services industry beginning January 1, 2000.
Improperly  functioning  trading  systems may result in settlement  problems and
liquidity issues. In addition, corporate and governmental data processing errors
may result in production problems for individual  companies and overall economic


                                       15
<PAGE>

uncertainties.  Earnings of individual  issuers will be affected by  remediation
costs,  which may be substantial and may be reported  inconsistently in U.S. and
foreign  financial  statements.  Accordingly,  the  Trust's  investments  may be
adversely affected.

SPECIAL INVESTMENT PRACTICES

      The Trust may  engage in the  following  investment  practices  to enhance
income or reduce investment risk, but has no current intention to do so.

      INTEREST  RATE AND OTHER HEDGING  TRANSACTIONS.  The Trust may purchase or
sell derivative  instruments (which are instruments that derive their value from
another  instrument,  security  or  index)  to  hedge  against  fluctuations  in
securities  prices or interest  rates.  The Trust's  transactions  in derivative
instruments may include the purchase or sale of futures contracts on securities,
securities  indices,  other indices,  other  financial  instruments;  options on
futures contracts; exchange-traded and over-the-counter options on securities or
indices;   index-linked  securities;   and  interest  rate  swaps.  The  Trust's
transactions  in derivative  instruments  involve a risk of loss or depreciation
due to: unanticipated adverse changes in securities prices,  interest rates, the
other  financial  instruments'  prices;  the  inability to close out a position;
default by the counterparty;  imperfect  correlation  between a position and the
desired  hedge;  tax  constraints  on  closing  out  positions;   and  portfolio
management  constraints on securities subject to such transactions.  The loss on
derivative  instruments (other than purchased options) may substantially  exceed
the Trust's initial investment in these instruments.  In addition, the Trust may
lose the entire  premium paid for purchased  options that expire before they can
be  profitably  exercised  by the Trust.  Transaction  costs will be incurred in
opening  and  closing  positions  in  derivative  instruments.  There  can be no
assurance that the Adviser's use of derivative  instruments will be advantageous
to the Trust.

      The Trust intends to use interest rate swaps for risk management  purposes
and not as a speculative  investment  and will typically use interest rate swaps
to shorten the average time to interest  rate reset of the Trust.  Interest rate
swaps involve the exchange by the Trust with another  party of their  respective
commitments to pay or receive interest, E.G., an exchange of fixed rate payments
for  floating  rate  payments.  The  use of  interest  rate  swaps  is a  highly
specialized  activity which involves  investment  techniques and risks different
from those  associated  with ordinary  portfolio  securities  transactions.  The
Adviser has had  limited  experience  in the use of interest  rate swaps but has
utilized other types of hedging  techniques.  If the Adviser is incorrect in its
forecasts of market values,  interest rates and other  applicable  factors,  the
investment  performance  of the Trust would be less favorable than what it would
have been if this investment technique were never used.

      SECURITIES  LENDING.  The Trust may seek to increase its income by lending
portfolio securities to broker-dealers or other institutional borrowers.  During
the existence of a loan,  the Trust 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 Trust may pay lending fees to such borrowers.  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
Trust's  Adviser to be of good standing and when, in the judgment of the Trust's
management,  the consideration which can be earned from securities loans of this
type,  net of  administrative  expenses  and any  finders  fees,  justifies  the
attendant risk. The financial condition of the borrower will be monitored by the
Adviser on an ongoing basis. The value of the securities  loaned will not exceed
30% of the Trust's total assets.

      REPURCHASE AGREEMENTS. The Trust may enter into repurchase agreements with
member banks of the Federal Reserve System or primary dealers in U.S. Government
securities. Under a repurchase agreement, the Trust buys securities at one price
and simultaneously promises to sell back those securities at a higher price. The
Trust's  repurchase  agreements  will provide  that the value of the  collateral
underlying  the  repurchase  agreement  will  always  be at  least  equal to the
repurchase  price,  including  any  accrued  interest  earned on the  repurchase
agreement,  and will be marked to market daily.  The repurchase  date is usually
within seven days of the original  purchase date. In all cases, the Adviser must
be  satisfied  with the  creditworthiness  of the other  party to the  agreement
before entering into a repurchase  agreement.  In the event of the bankruptcy of
the other party to a repurchase agreement,  the Trust might experience delays in


                                       16
<PAGE>

recovering  its cash.  To the extent  that,  in the  meantime,  the value of the
securities the Trust purchased may have declined,  the Trust could  experience a
loss.

      REVERSE  REPURCHASE  AGREEMENTS.  The Trust may also enter into  "reverse"
repurchase agreements which involve the sale of securities held and an agreement
to  repurchase  the  securities  at an  agreed-upon  price,  date,  and interest
payment.  Reverse repurchase agreements involve risks similar to those described
above under "-Use of Leverage"  leverage and expose the Trust to the credit risk
of the counterparty. The Trust will not hold more than 5% of its total assets in
reverse repurchase agreements.

                           MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES

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

THE ADVISER

      Eaton  Vance  Management  (the  "Adviser"  or "Eaton  Vance")  acts as the
Trust's  investment adviser under an Investment  Advisory  Agreement  ("Advisory
Agreement").  The Adviser's  principal  office is located at 24 Federal  Street,
Boston,  MA 02110.  Eaton Vance,  its affiliates and predecessor  companies have
been managing  assets of individuals  and  institutions  since 1924 and managing
investment  companies  since  1931.  Eaton Vance (or its  affiliates)  currently
serves as the investment adviser to investment  companies and various individual
and  institutional  clients with  combined  assets under  management of over $26
billion,  of which approximately $24 billion is in investment  companies.  Eaton
Vance is a wholly owned subsidiary of Eaton Vance Corp., a publicly held holding
company which  through its  subsidiaries  and  affiliates  engages  primarily in
investment management,  administration and marketing activities. The Adviser was
one of the first investment  advisers to manage a portfolio of Senior Loans in a
publicly  offered  investment  company and has done so continuously  since 1989.
Eaton  Vance  currently  offers the Eaton  Vance  Prime Rate  Reserves  Fund,  a
closed-end  investment company that commenced  investment  operations in August,
1989, and EV Classic Senior Floating-Rate Fund, a closed-end fund that commenced
investment operations in February, 1993. The Eaton Vance Prime Rate Reserve Fund
and the EV  Classic  Senior  Floating-Rate  Fund,  as well as an  offshore  fund
offered to non-U.S. investors, each invest substantially all of their respective
assets in the Senior Debt  Portfolio  (the  "Portfolio"),  a New York Trust that
serves as the vehicle  through which such funds invest in a common  portfolio of
Senior Loans.  For the  three-year  and five-year  periods ended August 31, 1998
with respect to the Eaton Vance Prime Rate Reserves Fund, and for the three-year
period ended August 31, 1998 with respect to the EV Classic Senior Floating-Rate
Fund, each such Fund was awarded five stars by Morningstar,  Inc. Morningstar is
an  independent   evaluator  of  public   investment   companies  and  publishes
"risk-adjusted   ratings"  on  various  groups  of  investment  companies.   The
Morningstar  Risk Adjusted Rating system  measures return  performance and risk.
The Eaton Vance Prime Rate Reserves Fund and the EV Classic Senior Floating-Rate
Fund are in the Morningstar Taxable Bond Fund category, which includes 1484 (for
such three year  period) and 912 (for such five year  period)  other  investment
companies. A fund receives five stars if its risk-adjusted performance is in the
top 10% of its rating category.  Various investment policies and restrictions of
the Eaton Vance Prime Rate Reserves Fund and the EV Classic Senior Floating Rate
Fund differ from those of the Trust.  The  investment  performance of such funds
and that of the Trust are expected to differ.  Past performance of such funds is
not necessarily  indicative of the Trust's  performance.  See "Management of the
Trust."

      Under the  general  supervision  of the  Trust's  Board of  Trustees,  the
Adviser  will carry out the  investment  and  reinvestment  of the assets of the
Trust,  will  furnish  continuously  an  investment  program with respect to the
Trust, will determine which securities  should be purchased,  sold or exchanged,
and will  implement such  determinations.  The Adviser will furnish to the Trust
investment advice and office  facilities,  equipment and personnel for servicing
the  investments  of the Trust.  The Adviser  will  compensate  all Trustees and
officers  of the Trust who are  members of the  Adviser's  organization  and who
render  investment  services to the Trust,  and will also  compensate  all other
Adviser personnel who provide research and investment  services to the Trust. In
return for these services,  facilities and payments, the Trust has agreed to pay


                                       17
<PAGE>

the Adviser as compensation  under the Advisory Agreement a fee in the amount of
 .85% of the average  daily gross assets of the Trust.  Gross assets of the Trust
shall be  calculated  by  deducting  all  liabilities  of the Trust  except  the
principal  amount  of  any  indebtedness  for  money  borrowed,  including  debt
securities  issued by the Trust.  The Adviser has agreed to waive its investment
advisory fee for the two-month period following the date of this Prospectus.

      Scott H. Page and Payson F.  Swaffield  are  co-portfolio  managers of the
Trust. Mr. Page has been an employee of Eaton Vance since 1989 and Mr. Swaffield
has been an employee of Eaton Vance since 1990.  Each has been a Vice  President
of Eaton Vance  since 1992 and has been  involved  in the  management  of Senior
Loans throughout his tenure at Eaton Vance.  They currently manage an investment
company  investing  primarily in Senior Loans with assets of approximately  $5.3
billion on August 31, 1998.

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

      The Trust has  engaged  Eaton Vance to act as its  administrator  under an
Administration   Agreement   (the   "Administration   Agreement").   Under   the
Administration  Agreement,  Eaton Vance is responsible for managing the business
affairs  of the  Trust,  subject  to the  supervision  of the  Trust's  Board of
Trustees. Eaton Vance will furnish to the Trust all office facilities, equipment
and  personnel  for  administering  the  affairs  of the  Trust.  Eaton  Vance's
administrative  services  include  recordkeeping,   preparation  and  filing  of
documents required to comply with federal and state securities laws, supervising
the activities of the Trust's custodian and transfer agent, providing assistance
in connection with the Trustees' and shareholders'  meetings,  providing service
in  connection  with any  repurchase  offers and other  administrative  services
necessary  to  conduct  the  Trust's  business.  In return  for these  services,
facilities  and  payments,  the  Trust  is  authorized  to pay  Eaton  Vance  as
compensation under the  Administration  Agreement a monthly fee in the amount of
 .25% of the  average  daily gross  assets of the Trust.  The  Administrator  has
agreed to waive its  administration  fee for the two-month  period following the
date of this Prospectus.

                           DISTRIBUTIONS AND TAXES

      The Trust intends to make monthly  distributions of net investment income,
after payment of dividends on any outstanding  preferred shares.  The Trust will
distribute  annually  any net  short-term  capital gain and any net capital gain
(which is the excess of net long-term  capital gain over net short-term  capital
loss.)  Distributions to Shareholders cannot be assured,  and the amount of each
monthly  distribution is likely to vary.  Initial  distributions to Shareholders
are  expected  to be paid  approximately  60 days after the  completion  of this
offering.  Until the Trust is fully  invested,  distributions  will be less than
they might  otherwise  be. While there are any  preferred  shares or  borrowings
outstanding,  the Trust may not be  permitted  to declare  any cash  dividend or
other distribution on its Shares under certain  circumstances.  See "Description
of Capital Structure."

      Distributions of the Trust's investment company taxable income (consisting
generally of net investment income and net short-term  capital gain) are taxable
to  Shareholders  as ordinary  income,  whether  paid in cash or  reinvested  in
additional Shares.  Distributions of the Trust's net capital gain ("capital gain
dividends"),  if any, are taxable to  Shareholders  at the rates  applicable  to
long-term capital gains,  regardless of the length of time Shares have been held
by  Shareholders.  Distributions,  if any, in excess of the Trust's earnings and
profits will first reduce the adjusted tax basis of a holder's Shares and, after
such adjusted tax basis has been reduced to zero, will constitute  capital gains
to such holder (assuming such Shares are held as a capital asset). See below for
a summary  of the  maximum  tax rates  applicable  to capital  gains  (including
capital gain dividends).

      The Trust  will  inform  Shareholders  of the source and tax status of all
distributions  promptly  after  the close of each  calendar  year.  The  Trust's
distributions  will  not  qualify  for  the  dividends-received   deduction  for
corporations.

      Selling  Shareholders  will generally  recognize gain or loss in an amount
equal to the  difference  between their adjusted tax basis in the Shares and the
amount  received.  If such Shares are held as a capital asset,  the gain or loss


                                       18
<PAGE>

will be a capital gain or loss. The maximum tax rates  applicable to net capital
gains  recognized by individuals and other  non-corporate  taxpayers are (i) the
same as the maximum  ordinary  income tax rate,  for capital assets held for one
year or less or (ii) 20% for  capital  assets  held for more than one year.  Any
loss recognized upon a taxable disposition of Shares held for six months or less
will be treated as a long-term  capital  loss to the extent of any capital  gain
dividends  received  with  respect to such Shares.  For purposes of  determining
whether  Shares  have been held for six months or less,  the  holding  period is
suspended  for  any  periods  during  which  the  Shareholder's  risk of loss is
diminished as a result of holding one or more other  positions in  substantially
similar or related property, or through certain options or short sales. Any loss
realized on a sale or exchange of Shares will be  disallowed to the extent those
Shares are replaced by other Shares within a period of 61 days beginning 30 days
before  and ending 30 days after the date of  disposition  of the Shares  (which
could occur,  for example,  if the  Shareholder is a participant in the Plan (as
defined  below)).  In that event,  the basis of the  replacement  Shares will be
adjusted to reflect the disallowed loss.

      An investor  should be aware that, if Shares are purchased  shortly before
the record  date for any  dividend  (including  a capital  gain  dividend),  the
investor  will pay full  price for the Shares and  receive  some  portion of the
purchase price back as a taxable distribution.  Shareholders that are not liable
for tax on their income and whose Shares are not  debt-financed are not required
to pay tax on dividends they receive from the Trust.  Taxable  distributions  to
individuals and certain other  non-corporate  Shareholders,  including those who
have not provided the Trust with their correct  taxpayer  identification  number
and other  required  certifications,  may be subject  to  "backup"  federal  tax
withholding of 31%.

      The foregoing  only  summarizes  some of the important  federal income tax
consequences to Shareholders of investing in Shares and does not address special
tax rules  applicable  to certain  types of  investors,  such as  corporate  and
foreign investors,  individual  retirement  accounts and other retirement plans.
There  may  be  other  federal,  state,  local  or  foreign  tax  considerations
applicable  to  a  particular  investor.  Investors  should  consult  their  tax
advisers.

                          DIVIDEND REINVESTMENT PLAN

      Pursuant to the Trust's Dividend Reinvestment Plan (the "Plan"),  unless a
Shareholder  otherwise  elects,  all  distributions of dividends  (including all
capital gain dividends) will be automatically reinvested in Shares.

      First Data Investor Services Group serves as agent for the Shareholders in
administering  the Plan.  Shareholders  who elect not to participate in the Plan
will  receive  all  distributions  of  dividends  in cash  paid by check  mailed
directly  to the  shareholder  of record (or if the Shares are held in street or
other nominee name, then to the nominee) by Boston Equiserve,  L.P., as dividend
disbursing agent.  Participation in the Plan is completely  voluntary and may be
terminated or resumed at any time without  penalty by written notice if received
by the Plan Agent not less than ten days prior to any dividend record date.

      Shares will be acquired by the Plan Agent or an independent  broker-dealer
for the  participants'  accounts,  depending  upon the  circumstances  described
below,  either (i) through receipt of additional  unissued but authorized Shares
from the Trust ("newly issued shares") or (ii) by purchase of outstanding Shares
on the open market  ("open-market  purchases") on the New York Stock Exchange or
elsewhere.  If on the  payment  date for the  dividend,  the net asset value per
Share  is equal to or less  than the  market  price  per  Share  plus  estimated
brokerage  commissions  (such  condition  being  referred  to herein as  "market
premium"), the Plan Agent will invest the dividend amount in newly issued Shares
on behalf of the participants.  The number of newly issued Shares to be credited
to each  participant's  account will be determined by dividing the dollar amount
of the  dividend  by the net asset  value per Share on the date the  Shares  are
issued,  provided that the maximum  discount from the then current  market price
per Share on the date of issuance may not exceed 5%. If on the dividend  payment
date the net asset  value per  Share is  greater  than the  market  value  (such
condition  being referred to herein as "market  discount"),  the Plan Agent will
invest the dividend amount in Shares  acquired on behalf of the  participants in
open-market purchases.

      In the event of a market  discount on the dividend  payment date, the Plan
Agent  will have until the last  business  day before the next date on which the


                                       19
<PAGE>

Shares  trade on an  "ex-dividend"  basis or in no event more than 30 days after
the  dividend  payment  date (the "last  purchase  date") to invest the dividend
amount in Shares acquired in open-market purchases.  It is contemplated that the
Trust will pay monthly  income  dividends.  Therefore,  the period  during which
open-market  purchases  can be made will exist only from the payment date of the
dividend  through the date before the next  "ex-dividend"  date which  typically
will be  approximately  ten days.  If,  before the Plan Agent has  completed its
open-market  purchases,  the market price of a Share exceeds the net asset value
per  Share,  the  average  per Share  purchase  price paid by the Plan Agent may
exceed the net asset value of the Trust's  Shares,  resulting in the acquisition
of fewer Shares than if the dividend had been paid in newly issued Shares on the
dividend  payment  date.  Because of the  foregoing  difficulty  with respect to
open-market  purchases,  the Plan  provides  that if the Plan Agent is unable to
invest the full dividend  amount in  open-market  purchases  during the purchase
period or if the market  discount shifts to a market premium during the purchase
period, the Plan Agent will cease making  open-market  purchases and will invest
the  uninvested  portion of the dividend  amount in newly  issued  Shares at the
close of business on the last purchase date.

      The  Plan  Agent  maintains  all  Shareholders'  accounts  in the Plan and
furnishes  written  confirmation of all transactions in the accounts,  including
information  needed by  Shareholders  for tax records.  Shares in the account of
each  Plan  participant  will be held by the Plan  Agent on  behalf  of the Plan
participant,  and each Shareholder  proxy will include those Shares purchased or
received   pursuant  to  the  Plan.  The  Plan  Agent  will  forward  all  proxy
solicitation materials to participants and vote proxies for Shares held pursuant
to the Plan in accordance with the instructions of the participants.

      In the case of Shareholders  such as banks,  brokers or nominees that hold
Shares for others who are the beneficial  owners, the Plan Agent will administer
the Plan on the basis of the number of Shares certified from time to time by the
record  Shareholder's  name and held for the  account of  beneficial  owners who
participate in the Plan.

      There will be no brokerage  charges with respect to Shares issued directly
by the  Trust as a result  of  dividends  payable  either  in Shares or in cash.
However,  each  participant  will pay a pro rata share of brokerage  commissions
incurred  with respect to the Plan Agent's  open-market  purchases in connection
with the reinvestment of dividends.

      Shareholders  participating in the Plan may receive benefits not available
to  Shareholders  not  participating  in the Plan.  If the  market  price  (plus
commissions) of the Trust's Shares is above their net asset value,  participants
in the Plan will receive  Shares of the Trust at less than they could  otherwise
purchase  them and will have Shares with a cash value  greater than the value of
any cash  distribution  they would have received on their Shares.  If the market
price plus commissions is below the net asset value,  participants  will receive
distributions  in Shares with a net asset value greater than the per Share value
of any cash  distribution  they would have  received on their  Shares.  However,
there may be insufficient  Shares available in the market to make  distributions
in Shares at prices  below the net asset value.  Also,  since the Trust does not
redeem it  Shares,  the  price on resale  may be more or less than the net asset
value.

      Experience  under  the Plan  may  indicate  that  changes  are  desirable.
Accordingly,  the Trust reserves the right to amend or terminate the Plan. There
is no direct  service charge to  participants  in the Plan;  however,  the Trust
reserves the right to amend the Plan to include a service  charge payable by the
participants.

Agent at P. O. Box 8030, Boston, MA  02266-8030.  Please call (800) 331-1710
between the hours of 9:00 a.m. and 5:00 p.m. Eastern Standard Time if you

                       DESCRIPTION OF CAPITAL STRUCTURE

 ......The Trust is an  unincorporated  business trust established under the laws
of the  Commonwealth of  Massachusetts by a Declaration of Trust dated September
23, 1998 (the  "Declaration  of Trust").  The Declaration of Trust provides that
the Trustees of the Trust may authorize separate classes of shares of beneficial
interest.  The  Trustees  have  authorized  an unlimited  number of Shares.  The
Declaration  of Trust also  authorizes  the Trust to borrow  money or  otherwise
obtain  credit  and  in  this  connection  issue  notes  or  other  evidence  of


                                       20
<PAGE>

indebtedness. The Trust intends to hold annual meetings of the holders of Shares
in compliance with the requirements of the New York Stock Exchange.

      SHARES.  The  Declaration of Trust permits the Trust to issue an unlimited
number of full and fractional Shares of beneficial interest,  $.01 par value per
Share.  Each Share represents an equal  proportionate  interest in the assets of
the Trust with each other Share in the Trust. Holders of Shares will be entitled
to the payment of dividends  when,  as and if declared by the Board of Trustees.
The 1940 Act or the terms of any  borrowings  or preferred  shares may limit the
payment  of  dividends  to the  holders of Shares.  Each  whole  Share  shall be
entitled to one vote as to matters on which it is  entitled to vote  pursuant to
the  terms  of the  Trust's  Declaration  of Trust  on file  with the SEC.  Upon
liquidation of the Trust,  after paying or adequately  providing for the payment
of all liabilities of the Trust and the  liquidation  preference with respect to
any outstanding preferred shares, and upon receipt of such releases, indemnities
and  refunding  agreements  as they deem  necessary  for their  protection,  the
Trustees may distribute  the remaining  assets of the Trust among the holders of
the Shares.  The Declaration of Trust provides that  shareholders are not liable
for any liabilities of the Trust,  requires inclusion of a clause to that effect
in every  agreement  entered  into by the  Trust  and  indemnifies  shareholders
against any such liability.  Although shareholders of an unincorporated business
trust established under Massachusetts law, in certain limited circumstances, may
be held  personally  liable for the obligations of the trust as though they were
general  partners,  the provisions of the  Declaration of Trust described in the
foregoing sentence make the likelihood of such personal liability remote.

      While there are any preferred shares or borrowings outstanding,  the Trust
may not be permitted to declare any cash dividend or other  distribution  on its
Shares,  unless at the time of such  declaration,  (i) all accrued  dividends on
preferred  shares or accrued  interest on  borrowings  has been paid and (2) the
value of the Trust's total assets (determined after deducting the amount of such
dividend or other  distribution),  less all liabilities and  indebtedness of the
Trust not  represented by senior  securities,  is at least 300% of the aggregate
amount of such  securities  representing  indebtedness  and at least 200% of the
aggregate  amount of  securities  representing  indebtedness  plus the aggregate
liquidation  value of the outstanding  preferred  shares  (expected to equal the
aggregate  original  purchase  price of the  outstanding  preferred  shares plus
redemption  premium,  if any,  together  with any accrued  and unpaid  dividends
thereon,  whether or not  earned or  declared  and on a  cumulative  basis).  In
addition  to the  requirements  of the 1940 Act,  the Trust may be  required  to
comply  with other  asset  coverage  requirements  as a  condition  of the Trust
obtaining  a  rating  of  the  preferred  shares  from a  nationally  recognized
statistical  rating  organization  or as a condition to borrowing  money.  These
requirements  may include an asset  coverage test more  stringent than under the
1940 Act. This  limitation on the Trust's ability to make  distributions  on its
Shares  could in  certain  circumstances  impair  the  ability  of the  Trust to
maintain its qualification for taxation as a regulated  investment company.  The
Trust intends,  however,  to the extent possible to purchase or redeem preferred
shares or to repay borrowings from time to time to maintain compliance with such
asset coverage  requirements and may pay special dividends to the holders of the
preferred shares in certain circumstances in connection with any such impairment
of the  Trust's  status  as a  regulated  investment  company.  See  "Investment
Objective,  Policies and Risks" and  "Distributions and Taxes." Depending on the
timing of any such  redemption or repayment,  the Trust may be required to pay a
premium in addition to the liquidation preference of the preferred shares or the
principal  amount of the  borrowings to the holders  thereof.  See  "Borrowings"
below.

      The Trust has no present intention of offering  additional Shares,  except
as  described  herein.  Other  offerings  of its Shares,  if made,  will require
approval of the Trust's Board of Trustees.  Any additional  offering will not be
sold at a price per Share below the then current net asset value  (exclusive  of
underwriting discounts and commissions) except in connection with an offering to
existing  Shareholders  or  with  the  consent  of a  majority  of  the  Trust's
outstanding Shares. The Shares have no preemptive rights.

      The Trust  generally  will not issue  share  certificates.  However,  upon
written  request to the Trust's  transfer  agent,  a share  certificate  will be
issued for any or all of the full  Shares  credited  to an  investor's  account.
Share  certificates which have been issued to an investor may be returned at any
time.

      REPURCHASE OF SHARES.  Because shares of closed-end  management investment
companies  frequently trade at a discount to their net asset values, the Trust's
Board  of  Trustees  has  determined  that  from  time  to time it may be in the


                                       21
<PAGE>

interest of Shareholders for the Trust to take corrective actions.  The Board of
Trustees, in consultation with the Administrator,  will review at least annually
the possibility of open market  repurchases  and/or tender offers for the Shares
and will consider such factors as the market price of the Shares,  the net asset
value of the Shares,  the  liquidity  of the assets of the Trust,  effect on the
Trust's expenses, whether such transactions would impair the Trust's status as a
regulated  investment  company or result in a failure to comply with  applicable
asset coverage  requirements,  general economic conditions and such other events
or  conditions  which may have a  material  effect  on the  Trust's  ability  to
consummate such transactions. There are no assurances that the Board of Trustees
will, in fact,  decide to undertake  either of these  actions or if  undertaken,
that such actions will result in the Trust's  Shares trading at a price which is
equal  to  or  approximates  their  net  asset  value.  In  recognition  of  the
possibility  that the Shares  might  trade at a discount  to net asset value and
that any such discount may not be in the interest of Shareholders,  the Board of
Trustees,  in consultation with the Administrator,  from time to time may review
possible  actions to reduce any such discount,  including but not limited to the
possibility of implementing a "managed  distribution" policy, which would entail
quarterly  payments  of  dividends  in  an  amount  equal  to a  pre-established
percentage  of the Trust's net asset value.  There can be no assurance  that the
Board of Trustees will decide to undertake  this action or that, if  undertaken,
such action would  result in the Shares  trading at a price equal to or close to
net asset  value per  Share.  The Board of  Trustees  might  also  consider  the
conversion  of the Trust to an  open-end  mutual  fund.  The  Board of  Trustees
believes, however, that the closed-end structure is desirable, given the Trust's
investment objective and policies.  Investors should assume,  therefore, that it
is  unlikely  that the Board of  Trustees  would vote to convert the Trust to an
open-end investment company. See "Description of Capital Structure."

      BORROWINGS. The Trust's Declaration of Trust authorizes the Trust, without
prior approval of the  Shareholders,  to borrow money in an amount up to 33 1/3%
of the Trust's total assets.  In this  connection,  the Trust may issue notes or
other evidence of indebtedness  (including bank borrowings or commercial  paper)
and may  secure  any  such  borrowings  by  mortgaging,  pledging  or  otherwise
subjecting as security the Trust's  assets.  In connection  with such borrowing,
the Trust may be required to maintain  minimum average  balances with the lender
or to pay a  commitment  or other fee to  maintain  a line of  credit.  Any such
requirements  will increase the cost of borrowing over the stated interest rate.
Under the  requirements of the 1940 Act, the Trust,  immediately  after any such
borrowings,  must have an "asset coverage" of at least 300%. With respect to any
such  borrowing,  asset  coverage  means the ratio  which the value of the total
assets of the Trust,  less all liabilities and  indebtedness  not represented by
senior securities (as defined in the 1940 Act), bears to the aggregate amount of
such borrowing  represented by senior securities by the Trust.  Certain types of
borrowing  may  result  in the  Trust  being  subject  to  covenants  in  credit
agreements  relating to asset  coverages or portfolio  composition or otherwise.
Such  restrictions may be more stringent than those imposed by the 1940 Act. The
rights of lenders to the Trust to receive interest on and repayment of principal
of any such  borrowings  will be  senior to those of the  Shareholders,  and the
terms  of any  such  borrowings  may  contain  provisions  which  limit  certain
activities of the Trust,  including the payment of dividends to  Shareholders in
certain circumstances. Further, the terms of any such borrowing may and the 1940
Act does (in certain  circumstances)  grant to the lenders to the Trust  certain
voting rights in the event of default in the payment of interest on or repayment
of principal.  In the event that such provisions would impair the Trust's status
as a  regulated  investment  company,  the  Trust,  subject  to its  ability  to
liquidate its relatively  illiquid  portfolio,  intends to repay the borrowings.
Any borrowing  will likely rank senior to or pari passu with all other  existing
and future  borrowings of the Trust.  See  "Investment  Objective,  Policies and
Risks - Use of  Leverage."  The Trust may also borrow up to an  additional 5% of
its total assets for temporary  purposes.  See "Investment  Restrictions" in the
Statement of Additional Information.

      The Trust currently  expects that it may enter into definitive  agreements
with  respect to a credit  facility  within two weeks  after the  closing of the
offer  and  sale of the  Shares  offered  hereby.  The  Trust  is  currently  in
negotiations  with a small  number  of money  center  banks to  arrange a senior
revolving credit facility  pursuant to which the Trust expects to be entitled to
borrow an amount equal to between approximately 25% and 50% of the Trust's total
assets as of the closing of the offer and sale of the Shares offered hereby. Any
such borrowings would constitute financial leverage. The terms of any agreements
relating to such a credit  facility have not been  determined and are subject to
definitive  agreement and other conditions but the Trust anticipates that such a
credit facility would have terms substantially  similar to the following:  (i) a
final maturity not expected to exceed three years subject to possible  extension
by the Trust;  (ii) with  respect to each draw under the  facility,  an interest
rate equal to the lesser of LIBOR plus a stated premium or an alternate rate on


                                       22
<PAGE>

the outstanding amount of each such draw, reset over periods ranging from one to
six  months;  and  (iii)  payment  by the  Trust of  certain  fees and  expenses
including an underwriting fee, a commitment fee on the average undrawn amount of
the  facility,  an ongoing  administration  fee and the  expenses of the lenders
under  the  facility  incurred  in  connection  therewith;   subject  to  market
conditions  which  may cause  the cost to be more or less,  the Trust  currently
expects  that the  aggregate  annualized  cost to the Trust over the life of the
facility of the  interest  rate and fees  referred to in clauses  (ii) and (iii)
will not exceed an amount equal to the stated  principal  amount of the facility
times an amount equal to 30-day LIBOR plus 60 basis points.  Individual draws on
the  facility  may have  maturities  ranging  from seven  days to one year.  The
facility is not  expected to be  convertible  into any other  securities  of the
Trust,  outstanding  amounts are expected to be prepayable by the Trust prior to
final maturity without  significant penalty and there are not expected to be any
sinking Trust or mandatory retirement  provisions.  Outstanding amounts would be
payable at maturity or such  earlier  times as  required by the  agreement.  The
Trust may be required to prepay outstanding  amounts under the facility or incur
a penalty rate of interest in the event of the  occurrence of certain  events of
default.  The Trust expects to indemnify the lenders under the facility  against
liabilities  they may incur in  connection  with the  facility.  In addition the
Trust expects that such a credit facility would contain  covenants which,  among
other things,  likely will limit the Trust's ability to pay dividends in certain
circumstances, incur additional debt, change its fundamental investment policies
and engage in certain transactions including mergers and consolidations, and may
require asset coverage ratios in addition to those required by the 1940 Act. The
Trust may be required to maintain a portion of its assets in cash or  high-grade
securities as a reserve against interest or principal payments and expenses. The
Trust expects that any credit facility would have customary  covenant,  negative
covenant and default  provisions.  There can be no assurance that the Trust will
enter  into  an  agreement  for  a  credit  facility  on  terms  and  conditions
representative  of the  foregoing,  or that  additional  material terms will not
apply. In addition,  if entered into, any such credit facility may in the future
be replaced or refinanced by one or more credit facilities having  substantially
different terms or by the issuance of preferred shares or debt securities.

      PREFERRED SHARES. The Trust's Declaration of Trust authorizes the issuance
of an unlimited number of shares of beneficial  interest with preference rights,
including the Preferred Shares,  having a par value of $.01 per share, in one or
more series,  with rights as determined  by the Board of Trustees,  by action of
the Board of Trustees without the approval of the Shareholders.  There can be no
assurance that the Preferred Shares will be issued or, if issued, that the terms
of such Preferred Shares will be as described in this Prospectus.

      Under the requirements of the 1940 Act, the Trust must,  immediately after
the issuance of the Preferred Shares, have an "asset coverage" of at least 200%.
With respect to the Preferred  Shares,  asset coverage means the ratio which the
value of the total assets of the Trust,  less all liability and indebtedness not
represented  by senior  securities  (as  defined in the 1940 Act),  bears to the
aggregate amount of senior securities representing indebtedness of the Trust, if
any, plus the aggregate  liquidation  preference of the Preferred Shares. If the
Trust seeks a rating of the Preferred Shares,  asset coverage  requirements,  in
addition  to those set forth in the 1940 Act,  may be imposed.  The  liquidation
value of the  Preferred  Shares is expected to equal  their  aggregate  original
purchase price plus redemption  premium,  if any,  together with any accrued and
unpaid  dividends  thereon  (on a  cumulative  basis),  whether or not earned or
declared.  The terms of the Preferred  Shares,  including  their  dividend rate,
voting  rights,  liquidation  preference  and  redemption  provisions,  will  be
determined by the Board of Trustees  (subject to applicable  law and the Trust's
Declaration of Trust) if and when it authorizes the Preferred Shares.  The Trust
may issue Preferred Shares that provide for the periodic  redetermination of the
dividend rate at relatively  short  intervals  through an auction or remarketing
procedure,  although the terms of the Preferred Shares may also enable the Trust
to lengthen such intervals.  At times,  the dividend rate as redetermined on the
Trust's  Preferred  Shares may  approach  or exceed  the  Trust's  return  after
expenses on the investment of proceeds from the Preferred Shares and the Trust's
leverage  structure would result in a lower rate of return to Shareholders  than
if the  Trust  were not so  structured.  However,  the Trust  believes  that the
floating or  variable  rate  nature of Senior  Loans in which the Trust  invests
helps  mitigate  against the risks of  increased  dividend  costs as a result of
redetermined market rates adversely impacting the return to Shareholders.

      LIQUIDATION  PREFERENCE.  In the  event of any  voluntary  or  involuntary
liquidation,  dissolution or winding up of the Trust, the terms of the Preferred
Shares may  entitle the holders of  Preferred  Shares to receive a  preferential
liquidating  distribution  (expected  to equal the original  purchase  price per
share  plus  redemption  premium,  if any,  together  with  accrued  and  unpaid
dividends, whether or not earned or declared and on a cumulative basis) before


                                       23
<PAGE>

any  distribution  of assets is made to holders of Shares.  After payment of the
full amount of the  liquidating  distribution  to which they are  entitled,  the
Preferred Shareholders would not be entitled to any further participation in any
distribution of assets by the Trust.

      ANTI-TAKEOVER   PROVISIONS  IN  THE  DECLARATION  OF  TRUST.  The  Trust's
Declaration of Trust includes  provisions that could have the effect of limiting
the ability of other  entities or persons to acquire  control of the Trust or to
change the  composition  of its Board of Trustees,  and could have the effect of
depriving  Shareholders of an opportunity to sell their Shares at a premium over
prevailing  market prices by  discouraging  a third party from seeking to obtain
control  of the Trust.  These  provisions  may have the  effect of  discouraging
attempts to acquire  control of the Trust,  which attempts could have the effect
of  increasing  the  expenses  of the  Trust  and  interfering  with the  normal
operation  of the Trust.  The Board of Trustees is divided  into three  classes,
with the term of one class expiring at each annual meeting of  Shareholders.  At
each annual meeting, one class of Trustees is elected to a three-year term. This
provision  could delay for up to two years the  replacement of a majority of the
Board of  Trustees.  A Trustee  may be removed  from  office only for cause by a
written  instrument signed by the remaining Trustees or by a vote of the holders
of at least  two-thirds  of the class of Shares of the Trust that  elected  such
Trustee and is entitled to vote on the matter.

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

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

      CONVERSION  TO OPEN-END  TRUST.  The Trust may be converted to an open-end
investment  company at any time if  approved by the lesser of (i) 2/3 or more of
the Trust's Shares and preferred  shares,  each voting separately as a class, or
(ii)  more than 50% of the  outstanding  Shares  and  preferred  shares,  voting
separately as a class if such  conversion is  recommended by at least 75% of the
Trustees then in office. If approved in the foregoing manner,  conversion of the
Trust  could not occur  until 90 days after the  Shareholders'  meeting at which
such  conversion  was  approved  and would also  require at least 30 days' prior
notice to all  Shareholders.  The  composition of the Trust's  portfolio  likely
would prohibit the Trust from  complying with  regulations of the SEC applicable
to open-end investment companies.  Accordingly,  conversion likely would require
significant  changes in the Trust's  investment  policies and  liquidation  of a
substantial  portion of its  relatively  illiquid  portfolio.  Conversion of the
Trust to an open-end investment company also would require the redemption of all
outstanding  Preferred  Shares and could  require the  repayment of  borrowings,
which would eliminate the leveraged  capital structure of the Trust with respect
to the Shares.  In the event of conversion,  the Shares would cease to be listed
on the New York Stock Exchange or other national  securities  exchange or market
system.  Shareholders of an open-end  investment company may require the company
to  redeem  their  shares  at any  time  (except  in  certain  circumstances  as
authorized by or under the 1940 Act) at their net asset value, less such



                                       24
<PAGE>

redemption  charge,  if any, as might be in effect at the time of a  redemption.
The Trust expects to pay all such  redemption  requests in cash,  but intends to
reserve  the  right  to pay  redemption  requests  in a  combination  of cash or
securities. If such partial payment in securities were made, investors may incur
brokerage  costs in  converting  such  securities  to cash.  If the  Trust  were
converted to an open-end  fund, it is likely that new Shares will be sold at net
asset value plus a sales load.

                                 UNDERWRITING

      The  underwriters  named  below  (the   "Underwriters"),   acting  through
___________________________,     and    as    their     representatives     (the
"Representatives") have severally agreed, subject to the terms and conditions of
the Underwriting  Agreement with the Trust (the  "Underwriting  Agreement"),  to
purchase from the Trust the number of Shares set forth opposite their respective
names.  The Underwriters are committed to purchase all of such Shares if any are
purchased.

              UNDERWRITER                          NUMBER OF SHARES





      The Trust has granted to the  Underwriters  an option,  exercisable for 45
days from the date of this Prospectus to purchase up to an additional  Shares to
cover  over-allotments,  if any, at the initial offering price. The Underwriters
may  exercise  such option  solely for the  purpose of covering  over-allotments
incurred  in the sale of the  Shares  offered  hereby.  To the  extent  that the
Underwriters  exercise this option,  each of the  Underwriters  will have a firm
commitment,  subject to certain conditions,  to purchase an additional number of
Shares proportionate to such Underwriter's initial commitment.

      As set  forth  in the  notes  to the  table  on the  cover  page  of  this
Prospectus,  Eaton Vance or an affiliate (not the Trust) from its own assets has
agreed to pay a  commission  to the  Underwriters  in the  amount of $ per Share
(____% of the public  offering  price per Share) or an aggregate  amount of $ ($
assuming full exercise of the  over-allotment  option) for all Shares covered by
this Prospectus.  Such payment will be the legal obligation of Eaton Vance or an
affiliate  and made out of its own assets and will not in any way  represent  an
obligation of the Trust or its Shareholders.  The  Representatives  have advised
the Trust  that the  Underwriters  may pay up to $ per Share  from such  payment
received  from Eaton Vance to selected  dealers who sell the Shares and that the
Underwriters and such dealers may reallow a concession of up to $0. per Share to
certain other dealers who sell Shares. In addition,  the Trust has agreed to pay
the Underwriters in the amount of $ in partial  reimbursement of their expenses.
Eaton Vance (or an affiliate) has agreed to pay all  organizational and offering
expenses of the Trust that exceed $.02 per share.

      Prior to this offering,  there has been no public market for the Shares or
any other  securities  of the Trust.  The Trust has  applied  for listing of its
Shares on the New York Stock  Exchange  under the symbol "EVF." In order to meet
the  requirements  for  listing the Shares on the New York Stock  Exchange,  the
Underwriters  have undertaken to sell lots of 100 or more Shares to a minimum of
2,000  beneficial  holders.  The minimum  investment  requirement  is 100 Shares
($1,000).

      The Trust and  Eaton  Vance  have each  agreed to  indemnify  the  several
Underwriters  for  or to  contribute  to  the  losses  arising  out  of  certain
liabilities, including liabilities under the Securities Act of 1933, as amended.

      The Trust has  agreed  not to offer or sell any  additional  Shares of the
Trust,  other than as contemplated by this Prospectus,  for a period of 180 days
after the date of the Underwriting  Agreement  without the prior written consent
of the Underwriters.

      The Underwriters may take certain actions to discourage short-term trading
of Shares during a period of time following the initial offering date.  Included
in these actions is the  withholding  of the  concession  and other  payments to
dealers in connection with Shares which were sold by such dealers and which are


                                       25
<PAGE>

repurchased for the account of the Underwriters during such period. In addition,
physical  delivery of certificates  representing  Shares is required to transfer
ownership of Shares for a certain  period.  Until the  distribution of Shares is
completed,  rules of the SEC may  limit  the  ability  of the  Underwriters  and
certain  selling  group  members  to bid  for and  purchase  the  Shares.  As an
exception to these rules,  the  Underwriters  are permitted to engage in certain
transactions that stabilize the price of the Shares.  Such transactions  consist
of bids or purchases for the purpose of pegging, fixing or maintaining the price
of the  Shares.  If the  Underwriters  create a short  position in the Shares in
connection with the offering,  I.E., if they sell more Shares than are set forth
on the cover page of this  Prospectus,  then the  Underwriters  may reduce  that
short position by purchasing  Shares in the open market.  The  Underwriters  may
also  elect to reduce  any short  position  by  exercising  all or a part of the
over-allotment  option described above. In general,  purchases of a security for
the purpose of stabilization or to reduce a short position could cause the price
of the security to be higher than it might be in the absence of such  purchases.
In  addition,  the  Underwriters  may impose  "penalty  bids" under  contractual
arrangements  with dealers  participating in the offering whereby it may reclaim
the selling  concession  with respect to Shares  distributed in the offering but
subsequently  purchased for the account of the  Underwriters in the open market.
Neither the Trust nor the Underwriters make any  representation or prediction as
to the  direction  or magnitude  of any effect that the  transactions  described
above may have on the price of the Shares.  In  addition,  neither the Trust nor
the Underwriters  make any  representation  that the Underwriters will engage in
such  transactions  or that  such  transactions,  once  commenced,  will  not be
discontinued without notice.

      Under the  terms of and  subject  to the  conditions  of the  Underwriting
Agreement,  the  Underwriters  are  committed to purchase and pay for all Shares
offered hereby if any are purchased. The Underwriting Agreement provides that it
may be terminated at or prior to the closing date for the purchase of the Shares
if, in the  judgement  of the  Representatives,  payment for the delivery of the
Shares is  rendered  impracticable  or  inadvisable  because  (1) trading in the
equity  securities  of the Trust is  suspended  by the  Securities  and Exchange
Commission, by an exchange that lists the Shares, or by the National Association
of Securities Dealers Automated Quotation National Market System, (2) additional
material governmental restrictions, not in force on the date of the Underwriting
Agreement,  have been imposed upon trading in securities generally or trading in
securities generally has been suspended on any U.S. securities exchange,  or (3)
a  general  banking  moratorium  has been  established  by  Federal  or New York
authorities,  or (4) any outbreak or material escalation of hostilities or other
calamity  or  crisis  occurs,  the  effect  of  which  is  such  as to  make  it
impracticable  to market any or all of the Shares.  The  Underwriting  Agreement
also may be terminated if any of the  conditions  specified in the  Underwriting
Agreement have not been fulfilled when and as required by such agreement.

      The  Trust  anticipates  that  the   Representatives   and  certain  other
Underwriters  may from time to time act as brokers or dealers in connection with
the  execution  of its  portfolio  transactions  after  they  have  ceased to be
Underwriters and, subject to certain restrictions, may act as such brokers while
they are Underwriters.

      _______________ will provide shareholder services to the Trust pursuant to
a  Shareholder  Servicing  Agreement  with Eaton  Vance.  Eaton Vance will pay a
monthly fee on an annual basis equal to 0.10% of the average weekly total assets
of the Trust for such services. See immediately below.

      Capitalized terms used in this Statement of Additional Information and not
otherwise defined have the meanings given them in the Trust's Prospectus.

              ADDITIONAL INVESTMENT INFORMATION AND RESTRICTIONS

LENDING  FEES.  In the process of buying,  selling and holding  Senior Loans the
Trust may  receive  and/or  pay  certain  fees.  These fees are in  addition  to
interest  payments  received and may include  facility  fees,  commitment  fees,
commissions  and prepayment  penalty fees.  When the Trust buys a Senior Loan it
may receive a facility fee and when it sells a Senior Loan it may pay a facility
fee. On an ongoing  basis,  the Trust may receive a commitment  fee based on the
undrawn  portion of the  underlying  line of credit portion of a Senior Loan. In
certain  circumstances,  the Trust may receive a prepayment penalty fee upon the
prepayment of a Senior Loan by a Borrower.  Other fees received by the Trust may
include covenant waiver fees and covenant modification fees.

BORROWER COVENANTS.  A Borrower must comply with various  restrictive  covenants
contained in a loan  agreement or note purchase  agreement  between the Borrower
and the Lender or lending syndicate (the "Loan Agreement").  Such covenants,  in
addition to  requiring  the  scheduled  payment of interest and  principal,  may
include   restrictions  on  dividend   payments  and  other   distributions   to
stockholders,  provisions  requiring the Borrower to maintain  specific  minimum
financial ratios, and limits on total debt. In addition,  the Loan Agreement may
contain a covenant  requiring  the  Borrower  to prepay the Senior Loan with any
free cash  flow.  Free cash flow is  generally  defined  as net cash flow  after
scheduled debt service payments and permitted capital expenditures, and includes
the  proceeds  from asset  dispositions  or sales of  securities.  A breach of a
covenant which is not waived by the Agent,  or by the lenders  directly,  as the
case may be, is  normally  an event of  acceleration;  i.e.,  the Agent,  or the
lenders  directly,  as the case may be,  has the  right to call the  outstanding
Senior Loan. The typical practice of an Agent or a Lender in relying exclusively
or  primarily  on reports  from the  Borrower may involve a risk of fraud by the
Borrower.  In the case of a Loan  Interest in the form of a  Participation,  the
agreement between the buyer and seller may limit the rights of the holder of the
loan  interest  to vote  on  certain  changes  which  may be  made  to the  Loan
Agreement, such as waiving a breach of a covenant. However, the holder of a loan
interest  will,  in  almost  all  cases,  have  the  right  to vote  on  certain
fundamental  issues  such as  changes in  principal  amount,  payment  dates and
interest rate.

ADMINISTRATION  OF LOANS.  In a typical  Senior Loan the Agent  administers  the
terms of the Loan Agreement.  In such cases,  the Agent is normally  responsible
for the collection of principal and interest  payments from the Borrower and the
apportionment  of these  payments  to the credit of all  institutions  which are
parties to the Loan  Agreement.  The Trust will generally rely upon the Agent or
an  intermediate  participant to receive and forward to the Trust its portion of
the  principal  and interest  payments on the Senior Loan.  Furthermore,  unless
under the terms of a  Participation  agreement the Portfolio has direct recourse
against the Borrower,  the Trust will rely on the Agent and the other members of
the lending  syndicate to use appropriate  credit remedies against the Borrower.
The Agent is typically  responsible  for  monitoring  compliance  with covenants
contained in the Loan Agreement based upon reports prepared by the Borrower. The
seller of the Senior Loan usually  does,  but is often not  obligated to, notify
holders of Senior Loans of any failures of compliance. The Agent may monitor the
value of the  collateral  and,  if the  value of the  collateral  declines,  may
accelerate  the Senior  Loan,  may give the Borrower an  opportunity  to provide
additional  collateral  or may seek  other  protection  for the  benefit  of the
participants  in the Senior Loan.  The Agent is  compensated by the Borrower for
providing  these  services under a Loan  Agreement,  and such  compensation  may
include special fees paid upon structuring and funding the Senior Loan and other
fees paid on a  continuing  basis.  With  respect to Senior  Loans for which the
Agent does not perform such administrative and  enforcement functions, the Trust


                                       B-2
<PAGE>




will  perform  such tasks on its own  behalf,  although a  collateral  bank will
typically  hold any  collateral  on behalf  of the  Trust and the other  lenders
pursuant to the applicable Loan Agreement.

      A financial  institution's  appointment as Agent may usually be terminated
in the event that it fails to observe the requisite  standard of care or becomes
insolvent,  enters Federal Deposit Insurance Corporation ("FDIC")  receivership,
or, if not FDIC insured, enters into bankruptcy  proceedings.  A successor Agent
would generally be appointed to replace the terminated Agent, and assets held by
the Agent under the Loan Agreement  should remain available to holders of Senior
Loans.  However,  if assets  held by the Agent for the benefit of the Trust were
determined  to be subject to the claims of the Agent's  general  creditors,  the
Trust  might incur  certain  costs and delays in  realizing  payment on a Senior
Loan, or suffer a loss of principal  and/or  interest.  In situations  involving
Intermediate Participants similar risks may arise.

PREPAYMENTS.  The Senior Loans in which the Trust  acquires loan  interests will
usually  require,  in addition to scheduled  payments of interest and principal,
the  prepayment  of the Senior Loan from free cash flow, as defined  above.  The
degree  to  which  Borrowers  prepay  Senior  Loans,  whether  as a  contractual
requirement  or  at  their  election,   may  be  affected  by  general  business
conditions,  the financial condition of the Borrower and competitive  conditions
among  lenders,  among others.  As such,  prepayments  cannot be predicted  with
accuracy.  Upon a prepayment,  either in part or in full, the actual outstanding
debt on which the Trust derives  interest income will be reduced.  However,  the
Trust may receive both a prepayment  penalty fee from the prepaying Borrower and
a facility fee upon the purchase of a new Senior Loan with the proceeds from the
prepayment of the former.  Prepayments  generally will not materially affect the
Trust's performance because the Trust should be able to reinvest  prepayments in
other Senior Loans that have similar or identical  yields and because receipt of
such fees may mitigate any adverse impact on the Trust's yield.

OTHER INFORMATION  REGARDING SENIOR LOANs. From time to time the Adviser and its
affiliates may borrow money from various banks in connection with their business
activities.  Such banks may also sell  interests  in Senior  Loans to or acquire
such interests from the Trust or may be intermediate  participants  with respect
to Senior  Loans in which the Trust owns  interests.  Such banks may also act as
Agents for Senior Loans in which the Trust owns interests.

      The  Trust may acquire  interests  in Senior  Loans which are  designed to
provide  temporary  or  "bridge"  financing  to a Borrower  pending  the sale of
identified  assets or the  arrangement of longer-term  loans or the issuance and
sale of debt  obligations.  The  Trust  may also  invest  in Loan  Interests  of
Borrowers who have obtained bridge loans from other parties. A Borrower's use of
bridge loans involves a risk that the Borrower may be unable to locate permanent
financing to replace the bridge loan, which may impair the Borrower's  perceived
creditworthiness.

      To  the extent that  collateral  consists  of the stock of the  Borrower's
subsidiaries  or other  affiliates,  the Trust  will be subject to the risk that
this  stock  will  decline  in value.  Such a  decline,  whether  as a result of
bankruptcy  proceedings  or  otherwise,  could  cause  the  Senior  Loan  to  be
undercollateralized  or unsecured.  In most credit agreements there is no formal
requirement to pledge additional  collateral.  In addition, the Trust may invest
in Senior Loans  guaranteed by, or fully secured by assets of,  shareholders  or
owners,  even if the Senior Loans are not otherwise  collateralized by assets of
the Borrower;  provided,  however, that such guarantees are fully secured. There
may be  temporary  periods  when the  principal  asset held by a Borrower is the
stock of a related company,  which may not legally be pledged to secure a Senior
Loan.  On occasions  when such stock cannot be pledged,  the Senior Loan will be
temporarily  unsecured  until the stock can be  pledged or is  exchanged  for or


                                      B-3
<PAGE>




replaced by other assets, which will be pledged as security for the Senior Loan.
However,  the Borrower's  ability to dispose of such  securities,  other than in
connection  with such pledge or  replacement,  will be strictly  limited for the
protection of the holders of Senior Loans and, indirectly,  Senior Loans. During
any such period in which the Senior Loan is temporarily  unsecured,  such Senior
Loans will not be treated as secured  Senior  Loans for  purposes of the Trust's
policy of investing in normal market conditions at least 80% of its total assets
in such secured Senior Loans.

      If a Borrower  becomes  involved in  bankruptcy  proceedings,  a court may
invalidate the Trust's  security  interest in the loan collateral or subordinate
the Trust's  rights  under the Senior Loan to the  interests  of the  Borrower's
unsecured  creditors.  Such action by a court could be based, for example,  on a
"fraudulent  conveyance"  claim to the effect that the  Borrower did not receive
fair  consideration for granting the security interest in the loan collateral to
the  Trust.  For  Senior  Loans  made  in  connection  with a  highly  leveraged
transaction,  consideration  for  granting  a  security  interest  may be deemed
inadequate  if the  proceeds  of the Loan were not  received  or retained by the
Borrower,  but were instead paid to other persons (such as  shareholders  of the
Borrower) in an amount which left the Borrower  insolvent or without  sufficient
working capital.  There are also other events,  such as the failure to perfect a
security interest due to faulty documentation or faulty official filings,  which
could  lead  to the  invalidation  of the  Trust's  security  interest  in  loan
collateral.  If the Trust's security  interest in loan collateral is invalidated
or the Senior Loan is  subordinated to other debt of a Borrower in bankruptcy or
other  proceedings,  it is unlikely  that the Trust would be able to recover the
full amount of the principal and interest due on the Loan.

INTEREST  RATE SWAPS.  The Trust may enter into interest rate swaps on either an
asset-based  or  liability-based  basis,  depending on whether it is hedging its
assets or its liabilities. For example, if the Trust holds a Senior Loan with an
interest  rate  that is reset  only  once  each  year,  it may swap the right to
receive  interest at this fixed rate for the right to receive interest at a rate
that is reset daily.  Such a swap position  would offset changes in the value of
the Senior Loan  because of  subsequent  changes in interest  rates.  This would
protect  the Trust from a decline in the value of the Senior  Loan due to rising
interest  rates,  but would also  limit its  ability  to  benefit  from  falling
interest rates.

      The  Trust will enter into interest rate swaps only on a net basis,  i.e.,
the two payment streams are netted out, with the Trust  receiving or paying,  as
the case may be,  only the net  amount of the two  payments.  Inasmuch  as these
transactions  are  entered  into  for good  faith  hedging  and risk  management
purposes and because a segregated account will be used, the Trust will not treat
them as being subject to the Trust's borrowing  restrictions.  The net amount of
the excess,  if any,  of the  Trust's  obligations  over its  entitlements  with
respect  to each  interest  rate swap will be  accrued  on a daily  basis and an
amount of cash or liquid securities having an aggregate net asset value at least
equal to the accrued  excess will be maintained  in a segregated  account by the
Trust's  custodian.  The Trust will not enter into any interest rate swap unless
the credit quality of the unsecured senior debt or the claims-paying  ability of
the other party thereto is considered to be investment grade by the Adviser.  If
there is a default by the other party to such a transaction, the Trust will have
contractual remedies pursuant to the agreements related to the transaction.  The
swap market has grown substantially in recent years with a large number of banks
and investment  banking firms acting both as principals and as agents  utilizing
standardized  swap  documentation.  As a  result,  the swap  market  has  become
relatively  liquid in comparison with the markets for other similar  instruments
which are traded in the interbank market.

      The  Trust may enter  into  interest  rate  swaps  only  with  respect  to
positions held in its portfolio. Interest rate swaps do not involve the delivery
of securities or other underlying assets or principal.  Accordingly, the risk of
loss with  respect  to  interest  rate  swaps is  limited  to the net  amount of


                                      B-4
<PAGE>




interest payments that the Trust is contractually  obligated to make or receive.
Since  interest  rate swaps are  individually  negotiated,  the Trust expects to
achieve  an  acceptable  degree of  correlation  between  its  rights to receive
interest  on Senior  Loans and its rights  and  obligations  to receive  and pay
interest pursuant to interest rate swaps.

CREDIT  DERIVATIVES.  The Trust may  engage in credit  derivative  transactions.
Default price risk  derivatives are linked to the price of reference  securities
or loans after a default by the issuer or borrower, respectively.  Market spread
derivatives are based on the risk that changes in market factors, such as credit
spreads,  can cause a decline in the value of a security,  loan or index.  There
are three basic transactional forms for credit derivatives;  swaps,  options and
structured  instruments.  The use of credit  derivatives is a highly specialized
activity which involves  strategies  and risks  different from those  associated
with ordinary  portfolio security  transactions.  If the Adviser is incorrect in
its forecasts of default risks, market spreads or other applicable factors,  the
investment  performance of the Trust would diminish  compared with what it would
have been if these  techniques were not used.  Moreover,  even if the Adviser is
correct in its forecasts,  there is a risk that a credit derivative position may
correlate  imperfectly  with the price of the asset or liability  being  hedged.
Credit  derivative  transaction  exposure  would be  limited to 10% of the total
assets of the Trust.

INVESTMENT  RESTRICTIONS.  The Trust has adopted certain fundamental  investment
restrictions  enumerated  below which may not be changed unless  authorized by a
shareholder  vote.  Except for such  fundamental  restrictions,  the  investment
objective and policies of the Trust are not fundamental policies and accordingly
may be changed by the Trustees of the Trust  without  obtaining  the approval of
the Trust's shareholders.

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

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

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

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

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

      (5)  Make loans to other  persons,  except by (a) the  acquisition of loan
interests,  debt  securities  and  other  obligations  in  which  the  Trust  is


                                      B-5
<PAGE>




authorized to invest in accordance  with its investment  objective and policies,
(b)  entering  into  repurchase  agreements,   and  (c)  lending  its  portfolio
securities;

      (6) Purchase any security if, as a result of such purchase, 25% or more of
the  Trust's  total  assets  (taken at current  value)  would be invested in the
securities  of  borrowers  and other  issuers  having their  principal  business
activities in the same industry (the electric,  gas, water and telephone utility
industries,  commercial banks,  thrift  institutions and finance companies being
treated as separate  industries for the purpose of this  restriction);  provided
that there is no limitation with respect to obligations  issued or guaranteed by
the U.S. Government or any of its agencies or instrumentalities;

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

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

      For the purpose of investment restriction (6), the Trust will consider all
relevant  factors  in  determining  who is the  issuer  of  the  loan  interest,
including:  the credit  quality of the  Borrower,  the amount and quality of the
collateral,  the  terms of the Loan  Agreement  and  other  relevant  agreements
(including  inter-creditor  agreements),  the degree to which the credit of such
interpositioned  person was deemed  material to the  decision  to  purchase  the
Senior Loan,  the interest rate  environment,  and general  economic  conditions
applicable to the Borrower and such interpositioned person.

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

      Notwithstanding  the investment  policies and  restrictions  of the Trust,
upon Trustee approval the Trust may invest its investable  assets in one or more
other  management  investment  companies to the extent permitted by the 1940 Act
and rules thereunder.

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

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

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

      Messrs.  Treynor  (Chairman) and Dwight are members of the Audit Committee
of the Board of Trustees of the Trust. The Audit  Committee's  functions include
making   recommendations   to  the  Trustees  regarding  the  selection  of  the
independent  certified  public  accountants,  and reviewing  matters relative to


                                      B-8
<PAGE>




trading and brokerage policies and practices,  accounting and auditing practices
and  procedures,  accounting  records,  internal  accounting  controls,  and the
functions  performed by the custodian,  transfer  agent and dividend  disbursing
agent of the Trust.

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

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

                     INVESTMENT ADVISORY AND OTHER SERVICES

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



                                      B-9

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

      The Advisory  Agreement  with the Adviser  continues in effect to February
28, 2000 and from year to year so long as such  continuance is approved at least
annually  (i) by the vote of a majority  of the  noninterested  Trustees  of the
Trust or of the Adviser cast in person at a meeting  specifically called for the
purpose  of voting on such  approval  and (ii) by the Board of  Trustees  of the
Trust or by vote of a majority of the  outstanding  interests of the Trust.  The
Trust's  Administration  Agreement continues in effect from year to year so long
as such  continuance  is approved at least annually by the vote of a majority of
the Trust's  Trustees.  Each  agreement  may be  terminated  at any time without
penalty on sixty (60) days' written notice by the Trustees of the Trust or Eaton
Vance, as applicable,  or by vote of the majority of the  outstanding  shares of
the Trust.  Each  agreement  will  terminate  automatically  in the event of its
assignment. Each agreement provides that, in the absence of willful misfeasance,
bad faith,  gross negligence or reckless  disregard of its obligations or duties
to the Trust under such agreements on the part of Eaton Vance, Eaton Vance shall
not be liable to the Trust for any loss  incurred,  to the extent not covered by
insurance.

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

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

                        DETERMINATION OF NET ASSET VALUE

      The  net  asset  value  per  Share  of the  Trust  is  determined  no less
frequently than weekly,  generally on the last day of the week that the New York
Stock Exchange (the "Exchange") is open for trading,  as of the close of regular
trading on the  Exchange  (normally  4:00 p.m.  New York time).  The Trust's net
asset value per share is determined by Investors  Bank & Trust Company  ("IBT"),
in the  manner  authorized  by the  Trustees  of the Trust.  Net asset  value is
computed by dividing the value of the Trust's total assets, less its liabilities
by the number of shares outstanding.

      Because  Senior  Loans are not  actively  traded in a public  market,  the
Adviser,  following procedures  established by the Trust's Trustees,  will value
the Senior  Loans held by the Trust at fair value.  In valuing a loan  interest,
Eaton Vance will consider  relevant factors,  data, and information,  including:
(i) the characteristics of and fundamental  analytical data relating to the loan
interest,  including the cost, size,  current  interest rate,  period until next
interest  rate reset,  maturity and base  lending  rate of the Senior Loan,  the
terms and conditions of the Loan and any related agreements, and the position of
the Loan in the Borrower's debt structure;  (ii) the nature,  adequacy and value
of the  collateral,  including the Trust's  rights,  remedies and interests with
respect to the collateral;  (iii) the creditworthiness of the Borrower, based on
an evaluation of its financial  condition,  financial statements and information
about  the  Borrower's  business,  cash  flows,  capital  structure  and  future
prospects;  (iv)  information  relating  to the  market  for the loan  interest,
including  price  quotations  (if  considered  reliable)  for and trading in the
Senior  Loan and  interests  in  similar  Loans and the market  environment  and
investor  attitudes  towards the loan interest and  interests in similar  Senior
Loans;  (v)  the  reputation  and  financial  condition  of the  Agent  and  any
intermediate  participants  in the Loan;  and (vi)  general  economic and market
conditions affecting the fair value of the loan interest.

      Non-loan holdings (other than short term obligations, but including listed
issues) may be valued on the basis of prices  furnished  by one or more  pricing
services which determine prices for normal,  institutional-size trading units of
such securities using market information, transactions for comparable securities
and various  relationships  between securities which are generally recognized by
institutional  traders. In certain  circumstances,  portfolio securities will be
valued at the last sale price on the  exchange  that is the  primary  market for
such securities, or the average of the last quoted bid price and asked price for
those securities for which the over-the-counter  market is the primary market or
for listed  securities in which there were no sales during the day. The value of
interest rate swaps will be determined in accordance  with a discounted  present
value formula and then confirmed by obtaining a bank quotation.

      Short-term  obligations  which  mature  in 60 days or less are  valued  at
amortized  cost,  if their  original term to maturity when acquired by the Trust
was 60 days or less,  or are valued at  amortized  cost using their value on the
61st day prior to maturity,  if their original term to maturity when acquired by
the Trust was more than 60 days,  unless in each case this is determined  not to
represent fair value.  Repurchase agreements will be valued by the Trust at cost
plus accrued  interest.  Securities for which there exist no price quotations or
valuations  and all other assets are valued at fair value as  determined in good
faith by or on behalf of the Trustees of the Trust.

                                PORTFOLIO TRADING

      Specific  decisions to purchase or sell  securities for the Trust are made
by  employees  of the Adviser who are  appointed  and  supervised  by its senior
officers.  Such  employees  may serve other  clients of the Adviser in a similar
capacity. Changes in the Trust's investments are reviewed by the Board.



                                      B-11
<PAGE>




      The Trust  will  acquire  Senior  Loans from  major  international  banks,
selected domestic  regional banks,  insurance  companies,  finance companies and
other financial  institutions.  In selecting  financial  institutions from which
Senior Loans may be acquired,  the Adviser will  consider,  among other factors,
the  financial  strength,  professional  ability,  level of service and research
capability of the institution.  While these financial institutions are generally
not required to  repurchase  Senior Loans which they have sold,  they may act as
principal or on an agency basis in connection with their sale by the Trust.

      Other  fixed-income  obligations  which may be  purchased  and sold by the
Trust are generally traded in the over-the-counter  market on a net basis (i.e.,
without commission) through broker-dealers or banks acting for their own account
rather than as brokers,  or otherwise  involve  transactions  directly  with the
issuers of such obligations.  The Trust may also purchase fixed-income and other
securities from underwriters, the cost of which may include undisclosed fees and
concessions to the underwriters. While it is anticipated that the Trust will not
pay  significant  brokerage  commissions,  on  occasion it may be  necessary  or
desirable to purchase or sell a security through a broker on an agency basis, in
which case the Trust  will incur a  brokerage  commission.  Although  spreads or
commissions on portfolio  transactions will, in the judgment of the Adviser,  be
reasonable  in  relation  to the  value of the  services  provided,  spreads  or
commissions exceeding those which another firm might charge may be paid to firms
who were  selected  to  execute  transactions  on  behalf  of the  Trust and the
Adviser's  other  clients for providing  brokerage and research  services to the
Adviser.

      The  frequency of portfolio  purchases  and sales,  known as the "turnover
rate," will vary from year to year.

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

                                      TAXES

      The  following  discussion  is  for  general  information  purposes  only.
Prospective  investors should consult their tax advisors  regarding the specific
federal income tax consequences of purchasing,  holding and disposing of Shares,
as well as the effects of state, local and foreign tax laws and any proposed tax
law changes.



                                      B-12
<PAGE>




      The Trust  intends  to  qualify  each year for  treatment  as a  regulated
investment company ("RIC"),  under the Internal Revenue Code of 1986, as amended
(the "Code"),  in order to reduce or eliminate federal income tax.  Accordingly,
the Trust  intends to satisfy  certain  requirements  relating to sources of its
income and  diversification  of its assets and to distribute a sufficient amount
of its investment company taxable income so as to effect such qualification.

      Dividends  and  other  distributions  declared  by the  Trust in  October,
November or December of any year and payable to Shareholders of record on a date
in any of those  months  will be  deemed  to have  been  paid by the  Trust  and
received by the Shareholders on December 31st of that year if the  distributions
are paid by the Trust during January of the following year.  Accordingly,  those
distributions  will be taxed to Shareholders for the year in which that December
31st falls.

      To avoid a non-deductible 4% federal excise tax, the Trust must distribute
to its  Shareholders by the end of each calendar year  substantially  all of its
ordinary  income for that year and  capital  gain net  income  for the  one-year
period  ending on October 31 of that year,  plus certain  other  amounts.  Under
current law, provided that the Trust qualifies as a RIC, it should not be liable
for any  income,  corporate  excise  or  franchise  tax in the  Commonwealth  of
Massachusetts.

      Income and gains from  investments in securities of foreign issuers may be
subject to foreign  income,  withholding  or other  taxes,  which may reduce the
Trust's yield and/or total return. Tax conventions between certain countries and
the United States may reduce or eliminate these foreign taxes. Shareholders will
not be able to claim any foreign tax credit or  deduction  with respect to these
foreign taxes.

      Certain  investments  of the Trust may bear  original  issue  discount  or
market  discount  for tax  purposes.  The Trust will be  required  to include in
income  each year a portion of such  original  issue  discount  and may elect to
include in income  each year a portion of such  market  discount.  The Trust may
have to dispose of investments that it would otherwise have continued to hold to
provide cash to enable it to satisfy its distribution  requirements with respect
to such income.

      Some  of the  Trust's  investment  practices  (including  those  involving
certain risk management  transactions)  may be subject to special  provisions of
the Code that,  among other things,  may defer the Trust's  deduction of certain
losses and  affect the  holding  period of certain  securities  it holds and the
character of certain  gains or losses it  realizes.  These  provisions  may also
require the Trust to recognize income or gain without  receiving cash with which
to make  distributions  in the amounts  necessary  to satisfy  the  distribution
requirements  for avoiding  income and excise taxes.  The Trust will monitor its
transactions  and may make certain tax elections to mitigate the effect of these
rules and prevent its disqualification as a RIC.

                                OTHER INFORMATION

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


                                      B-13
<PAGE>




shareholder  liability is limited to  circumstances in which the Trust itself is
unable to meet its  obligations.  The Trust believes the risk of any shareholder
incurring any liability for the obligations of the Trust is remote.

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

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

      As of the date of this  Statement of Additional  Information,  Eaton Vance
controlled  the Fund by virtue of owning  directly  and  indirectly  100% of the
outstanding voting shares of the Fund.

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

                                   APPENDIX A

                           RATINGS OF CORPORATE BONDS

DESCRIPTION OF CORPORATE BOND RATINGs OF STANDARD & POOR'S RATING GROUP:

      AAA -- Bonds rated AAA have the highest rating  assigned by S&P.  Capacity
to pay interest and repay principal is extremely strong.

      AA -- Bonds rated AA have a very strong capacity to pay interest and repay
principal and differ from the highest rated issues only in small degree.

      A --  Bond  rated A have a  strong  capacity  to pay  interest  and  repay
principal  although they are somewhat more susceptible to the adverse effects of
changes in  circumstances  and economic  conditions  than  obligations in higher
rated categories.

      BBB -- Bonds rated BBB are regarded as having an adequate  capacity to pay
interest and repay principal.  Whereas they 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
bonds in this category than for bonds in higher rated categories.

      BB -- Bonds rated BB have less  near-term  vulnerability  to default  than
other speculative grade debt. However,  they face major ongoing uncertainties or
exposure to adverse business,  financial or economic conditions which could lead
to inadequate capacity to meet timely interest and principal payments.

      B -- Bonds rated B have a greater  vulnerability  to default but presently
have the capacity to meeting interest payments and principal repayments. Adverse
business,  financial  or economic  conditions  would likely  impair  capacity or
willingness to pay interest and repay principal.

      CCC --  Bonds  rated  CCC have a  current  identifiable  vulnerability  to
default and are  dependent  upon  favorable  business,  financial  and  economic
conditions to meet timely  payments of interest and  repayment of principal.  In
the event of adverse business,  financial or economic  conditions,  they are not
likely to have the capacity to pay interest and repay principal.

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

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

      D --  Bonds  rated  D are in  default,  and  payment  of  interest  and/or
repayment of principal is in arrears.

      S&P's  letter  ratings may be modified by the  addition of a plus (+) or a
minus (-) sign  designation,  which is used to show relative standing within the
major rating categories, except in the AAA (Prime Grade) category.

<PAGE>




DESCRIPTION OF BOND RATINGS OF MOODY'S INVESTORS SERVICE, INC.

      Aaa -- Bonds  which are rated  Aaa are  judged to be of the best  quality.
They carry the smallest  degree of investment risk and generally are referred to
as  "gilt  edge."  Interest   payments  are  protected  by  a  large  or  by  an
exceptionally   stable  margin  and  principal  is  secure.  While  the  various
protective  elements are likely to change, such changes as can be visualized are
most unlikely to impair the 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 generally are known as
high grade bonds.  They are rated lower than the best bonds  because  margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements  may be of greater  amplitude  or there may be other  elements  present
which make the long-term risks appear somewhat larger than in Aaa securities.

      A -- Bonds which are rated A possess many favorable investment  attributes
and are to be  considered  as upper medium  grade  obligations.  Factors  giving
security to principal and interest are considered adequate,  but elements may be
present which suggest a susceptibility to impairment sometime in the future.

      Baa  --  Bonds  which  are  rated  Baa  are  considered  as  medium  grade
obligations,  i.e.,  they are  neither  highly  protected  nor  poorly  secured.
Interest  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,  therefore,  not well
safeguarded  during  both good and bad times  over the  future.  Uncertainty  of
position characterizes bonds in this class.

      B --  Bonds  which  are  rated B  generally  lack  characteristics  of the
desirable  investment.  Assurance  of  interest  and  principal  payments  or of
maintenance  of other terms of the contract  over any long period of time may be
small.

      Caa -- Bonds which are rated Caa are of poor standing.  Such issues may be
in default or there may be present  elements of danger with respect to principal
or interest.

      Ca -- Bonds which are rated Ca present  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.

Moody's  applies the numerical  modifiers 1, 2 and 3 to show  relative  standing
within  the  major  rating  categories,  except in the Aaa  category  and in the
categories  below B. The  modifier 1 indicates a ranking for the security in the
higher end of a rating category;  the modifier 2 indicates a mid-range  ranking;
and the modifier 3 indicates a ranking in the lower end of a rating category.

      The Registrant's By-Laws filed herewith and the Underwriting Agreement to
be filed contain provisions limiting the liability, and providing for
indemnification, of the Trustees and officers under certain circumstances.

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

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

                                    TRUSTEES

      SECTION 2.1. MANAGEMENT OF THE TRUST. The business and affairs of the
Trust shall be managed by the Trustees and they shall have all powers and
authority necessary, appropriate or desirable to perform that function.

      SECTION 2.2. NUMBER OF TRUSTEES. The number of Trustees shall be such
number as shall be fixed from time to time by a written instrument signed by a
majority of the Trustees, provided, however, that the number of Trustees shall
in no event be less than two (2) nor more than fifteen (15). No reduction in the
number of Trustees shall have the effect of removing any Trustee from office
prior to the expiration of his term unless the Trustee is specifically removed
pursuant to Section 2.2 of this Article II at the time of decrease.

      SECTION 2.3. TERM OF OFFICE OF TRUSTEES. The Board of Trustees shall be
divided into three classes. Within the limits above specified, the number of the
Trustees in each class and the class which each Trustee is assigned shall be
determined by resolution of the Board of Trustees. The term of office of the
first class shall expire on the date of the first annual meeting of Shareholders
or special meeting in lieu thereof following the effective date of the
Registration Statement. The term of office of the second class shall expire on
the date of the second annual meeting of Shareholders or special meeting in lieu
thereof following the effective date of the Registration Statement. The term of
office of the third class shall expire on the date of the third annual meeting
of Shareholders or special meeting in lieu thereof following the effective date
of the Registration Statement. Upon expiration of the term of office of each
class as set forth above, the number of Trustees in such class, as determined by
the Board of Trustees, shall be elected for a term expiring on the date of the
third annual meeting of Shareholders or special meeting in lieu thereof
following such expiration to succeed the Trustees whose terms of office expire.
The Trustees shall be elected at an annual meeting of the Shareholders or
special meeting in lieu thereof called for that purpose, except as provided in
Section 2.3 of this Article and each Trustee elected shall hold office until his
successor shall have been elected and shall have qualified; except (a) that any
Trustee may resign his trust (without need for prior or subsequent accounting)
by an instrument in writing signed by him and delivered to the other Trustees,
which shall take effect upon such delivery or upon such later date as is
specified therein; (b) that any Trustee may be removed (provided the aggregate
number of Trustees after such removal shall not be less than the number required
by Section 2.1 hereof) for cause, at any time by written instrument, signed by
the remaining Trustees, specifying the date when such removal shall become
effective; and (c) that any Trustee who requests in writing to be retired or who
has become incapacitated by illness or injury may be retired by written
instrument signed by a majority of the other Trustees, and he shall execute and
deliver such documents as the remaining Trustees shall require for the purpose
of conveying to the Fund or the remaining Trustees any Fund property held in the
name of the resigning or removed Trustee. Upon the incapacity or death of any
Trustee, his legal representative shall execute and deliver on his behalf such
document as the remaining Trustees shall require as provided in the preceding
sentence.

<PAGE>




      SECTION 2.4. RESIGNATION AND APPOINTMENT OF TRUSTEES. In case of the
declination, death, resignation, retirement, removal or inability of any of the
Trustees, or in case a vacancy shall, by reason of any increase in number, or
for any other reason, exist, the remaining Trustees or, prior to the public
offering of Shares of the Fund, if only one Trustee shall then remain in office,
the remaining Trustee, shall fill such vacancy by appointing such other person
as they, or anyone of them, in their discretion, shall see fit. Such appointment
shall be evidenced by a written instrument signed by a majority of the remaining
Trustees or by the remaining Trustee, as the case may be. Any such appointment
shall not become effective, however, until the person named in the written
instrument or appointment shall have accepted in writing such appointment and
agreed in writing to be bound by the terms of the Declaration. Within twelve
months of such appointment, the Trustees shall cause notice of such appointment
to be mailed to each Shareholder at his address as recorded on the books of the
Fund. An appointment of a Trustee may be made by the Trustees then in office and
notice thereof mailed to Shareholders as aforesaid in anticipation of a vacancy
to occur by reason of retirement, resignation or increase in number of Trustees
effective at a later date, provided that said appointment shall become effective
only at or after the effective date of said retirement, resignation or increase
in number of Trustees. The power of appointment is subject to the provisions of
Section 16(a) of the 1940 Act.

      SECTION 2.5. VACANCIES. The death, declination, resignation, retirement,
removal or incapacity of the Trustees, or any one of them, shall not operate to
annul the Fund or to remove any existing agency created pursuant to the terms of
this Declaration. Whenever a vacancy in the number of Trustees shall occur,
until such vacancy is filled as provided in Section 2.3, the Trustees in office,
regardless of their number, shall have all the duties imposed upon the Trustees
by the Declaration. A written instrument certifying the existence of such
vacancy signed by a majority of the Trustees shall be conclusive evidence of the
existence of such vacancy.

      SECTION 2.6. DELEGATION OF POWER TO OTHER TRUSTEES. Subject to the
provisions of the 1940 Act, any Trustee may, by power of attorney, delegate his
power for a period not exceeding six (6) months at any one time to any other
Trustee or Trustees; provided that in no case shall less than two (2) Trustees
personally exercise the powers grated to the Trustees under the Declaration
except as herein otherwise expressly provided.

      SECTION 2.7. REMOVAL OF TRUSTEES. The Fund shall comply with the
provisions of Section 16(c) of the 1940 Act as though applicable to the Fund,
and with interpretations hereof by the Commission staff, insofar as such
provisions and interpretations provide for the removal of trustees of common-law
trusts and the calling of Shareholder meetings for such purpose; provided,
however, that the Fund may at any time or from time to time apply to the
Commission for one or more exemptions from all or part of said Section 16(c) or
a staff interpretation thereof and, if exemptive order(s) or interpretation(s)
are issued or provided by the Commission or its staff, such order(s) or
interpretation(s) shall be deemed part of Section 16(c) for the purpose of
applying this Section 2.6.

      SECTION 2.8. GENERAL POWERS. The Trustees in all instances shall act as
principals for and on behalf of the Trust and their acts shall bind the Trust.
The business and affairs of the Trust shall be managed by the Trustees and they
shall have full power and authority to do any and all acts and to make and
execute any and all contracts and instruments that they may consider necessary,
appropriate or desirable in connection with the management of the Trust. The
Trustees shall not be bound or limited in any way by present or future laws,
practices or customs in regard to trust investments or to other investments
which may be made by fiduciaries, but shall have full authority and power to
make any and all investments which they, in their uncontrolled discretion, shall
deem proper to promote, implement or accomplish the various objectives and
interests of the Trust and of its Classes and Series. The Trustees shall have
full power and authority to adopt such accounting and tax accounting practices
as they consider appropriate for the Trust and for any Class or Series. The
Trustees shall have exclusive and absolute control over the Trust Property and


                                       4
<PAGE>




over the business of the Trust to the same extent as if the Trustees were the
sole owners of the Trust Property and business in their own right, and with such
full powers of delegation as the Trustees may exercise from time to time. The
Trustees shall have power to conduct the business of the Trust and carry on its
operations in any and all of its branches and maintain offices both within and
without The Commonwealth of Massachusetts, in any and all states of the United
States of America, in the District of Columbia, and in any and all
commonwealths, territories, dependencies, colonies, possessions, agencies, and
instrumentalities of the United States of America and of foreign governments,
and to do all such other things as they deem necessary, appropriate or desirable
in order to promote or implement the interests of the Trust or of any Class or
Series although such things are not herein specifically mentioned. Any
determination as to what is in the interests of the Trust or of any Class or
Series made by the Trustees in good faith shall be conclusive and binding upon
all Shareholders. In construing the provisions of this Declaration, the
presumption shall be in favor of a grant of plenary power and authority to the
Trustees.

      The enumeration of any specific power in this Declaration shall not be
construed as limiting the aforesaid general and plenary powers.

      SECTION 2.9.  INVESTMENTS.  The Trustees shall have full power and
authority:

            (a) To operate as and carry on the business of an investment
      company, and exercise all the powers necessary and appropriate to the
      conduct of such operations.

            (b) To acquire or buy, and invest Trust Property in, own, hold for
      investment or otherwise, and to sell or otherwise dispose of, all types
      and kinds of securities and investments of any kind including, but not
      limited to, stocks, profit-sharing interests or participations and all

all of the assets of any Class or Series) and invest the proceeds of such
disposition, in securities issued by one or more other investment companies

Trust Property shall vest automatically in each Person who may hereafter become
a Trustee. Upon the termination of the term of office, resignation, removal or

interest in any of the Trust Property, and the right, title and interest of such
Trustee in the Trust Property shall vest automatically in the remaining
Trustees.

desirable, and, subject to the voting powers of one or more Classes or Series,
to amend and repeal such By-Laws. Unless the By-Laws specifically require that

provision of the By-Laws, any provision of the By-Laws may be amended or
repealed by the Trustees without Shareholder authorization or approval.

      SECTION 2.12. DISTRIBUTION AND REPURCHASE OF SHARES. The Trustees shall

Trustees shall have full power to provide for the distribution of Shares either
through one or more principal underwriters or by the Trust itself, or both.

      SECTION 2.13. DELEGATION. The Trustees shall have full power and authority
to delegate from time to time to such of their number or to officers, employees
or agents of the Trust or to other Persons the doing of such things and
execution of such agreements or other instruments either in the name of the
Trust or any Class or Series of the Trust or the names of the Trustees or
otherwise as the Trustees may deem desirable or expedient.

      SECTION 2.14. COLLECTION AND PAYMENT. The Trustees shall have full power
and authority to collect all property due to the Trust; to pay all claims,
including taxes, against the Trust or Trust Property; to prosecute, defend,
compromise, settle or abandon any claims relating to the Trust or Trust
Property; to foreclose any security interest securing any obligations, by virtue
of which any property is owed to the Trust; and to enter into releases,
agreements and other instruments.

      SECTION 2.15. EXPENSES. The Trustees shall have full power and authority
to incur on behalf of the Trust or any Class or Series and pay any costs or
expenses which the Trustees deem necessary, appropriate, desirable or incidental
to carry out, implement or enhance the business or operations of the Trust or
any Class or Series thereof, and to pay compensation from the funds of the Trust
to themselves as Trustees. The Trustees shall determine the compensation of all
officers, employees and Trustees of the Trust. The Trustees shall have full
power and authority to cause the Trust to charge all or any part of any cost,
expense or expenditure (including without limitation any expense of selling or


                                       7
<PAGE>




distributing Shares) or tax against the principal or capital of the Trust or any
Class or Series, and to credit all or any part of the profit, income or receipt
to the principal or capital of the Trust or any Class or Series.

      SECTION 2.16. COMMITTEES. The Trustees may appoint from their own number,
and terminate, any one or more committees consisting of two or more Trustees,
including an executive committee which may, when the Trustees are not in
session, exercise some or all of the power and authority of the Trustees as the
Trustees may determine.

      SECTION 2.17. MISCELLANEOUS POWERS. The Trustees shall have full power and
authority to: (a) distribute to Shareholders all or any part of the earnings or
profits, surplus (including paid-in surplus), capital (including paid-in
capital) or assets of the Trust or of any Class or Series, the amount of such

investments, and insurance policies insuring the Shareholders, Trustees,
officers, employees, agents, investment advisers or managers, principal
underwriters, or independent contractors of the Trust individually against all
claims and liabilities of every nature arising by reason of holding, being or
having held any such office or position, or by reason of any action alleged to
have been taken or omitted by any such person as Shareholder, Trustee, officer,
employee, agent, investment adviser or manager, principal underwriter, or
independent contractor, including any action taken or omitted that may be
determined to constitute negligence, whether or not the Trust would have the
power to indemnify such person against such liability; (e) establish pension,
profit-sharing, share purchase, and other retirement, incentive and benefit
plans for any Trustees, officers, employees and agents of the Trust; (f)
indemnify or reimburse any Person with whom the Trust or any Class or Series

the indebtedness or contractual obligations of other Persons; (h) determine and
change the fiscal year of the Trust and the methods by which its books, accounts

      SECTION 2.18. LITIGATION. The Trustees shall have full power and
authority, in the name and on behalf of the Trust, to engage in and to
prosecute, defend, compromise, settle, abandon, or adjust by arbitration or
otherwise, any actions, suits, proceedings, disputes, claims and demands

its good faith business judgment, to dismiss or terminate any action, suit,
proceeding, dispute, claim or demand, derivative or otherwise, brought by any
Person, including a Shareholder in his own name or in the name of the Trust or
any Class or Series thereof, whether or not the Trust or any Class or Series
thereof or any of the Trustees may be named individually therein or the subject

Shares by such other party as principal or as agent of the Trust.

      SECTION 3.2. INVESTMENT ADVISER. The Trustees may, subject to any

undertake to furnish the Trust investment advisory and research facilities and
services and such other facilities and services, if any, as the Trustees shall
consider desirable and all upon such terms and conditions as the Trustees may in

the Trustees may authorize the Investment Adviser, in its discretion and without
any prior consultation with the Trust, to buy, sell, lend and otherwise trade
and deal in any and all securities, commodity contracts and other investments
and assets of the Trust and to engage in and employ all types of transactions

such terms and conditions as may be agreed upon between the Investment Adviser
and such sub-investment adviser and approved by the Trustees.

      SECTION 3.3. ADMINISTRATOR. The Trustees may in their discretion from time
to time authorize the Trust to enter into one or more administration agreements,

Administrator to employ one or more sub-administrators from time to time to
perform such of the acts and services of the Administrator and upon such terms
and conditions as may be agreed upon between the Administrator and such
sub-administrator and approved by the Trustees.

      SECTION 3.4. OTHER SERVICE PROVIDERS. The Trustees may in their discretion

                                       9
<PAGE>




            (i) any of the Shareholders, Trustees or officers of the Trust is a
      shareholder, creditor, director, officer, partner, trustee or employee of
      or has any interest in any Person or any parent or affiliate of any such
      Person, with which a contract or agreement of the character described in
      this Article III has been or will be made, or that any such Person, or any
      parent or affiliate thereof, is a Shareholder of or has an interest in the
      Trust, or that

            (ii) any such Person also has similar contracts, agreements or plans
      with other investment companies (including, without limitation, the
      investment companies referred to in the last paragraph of Section 2.9) or
      Persons, or has other business activities or interests,

shall not affect in any way the validity of any such contract, agreement or plan
or disqualify any Shareholder, Trustee or officer of the Trust from authorizing,
voting upon or executing the same or create any liability or accountability to
the Trust or its Shareholders.


                                   ARTICLE IV

         LIMITATIONS OF LIABILITY OF SHAREHOLDERS, TRUSTEES AND OTHERS

      SECTION 4.1. NO PERSONAL LIABILITY OF SHAREHOLDERS, TRUSTEES, OFFICERS AND
EMPLOYEES. No Shareholder shall be subject to any personal liability whatsoever
to any Person in connection with Trust Property or the acts, obligations or
affairs of the Trust or any Class or Series thereof. All Persons dealing or
contracting with the Trustees as such or with the Trust or any Class or Series
thereof or having any claim against the Trust or any Class or Series thereof
shall have recourse only to the Trust or such Class or Series for the payment of
their claims or for the payment or satisfaction of claims, obligations or
liabilities arising out of such dealings or contracts. No Trustee, officer or
employee of the Trust, whether past, present or future, shall be subject to any
personal liability whatsoever to any such Person, and all such Persons shall
look solely to the Trust Property, or to the assets of one or more specific
Class or Series of the Trust if the claim arises from the act, omission or other
conduct of such Trustee, officer or employee with respect to only such Class or
Series, for satisfaction of claims of any nature arising in connection with the
affairs of the Trust or such Class or Series. If any Shareholder, Trustee,
officer or employee, as such, of the Trust is made a party to any suit or
proceeding to enforce any such liability of the Trust or any Class or Series
thereof, he shall not, on account thereof, be held to any personal liability.

      SECTION 4.2. TRUSTEE'S GOOD FAITH ACTION; ADVICE TO OTHERS; NO BOND OR
SURETY. The exercise by the Trustees of their powers and discretions hereunder
shall be binding upon all Interested Parties. A Trustee shall not be liable for
errors of judgment or mistakes of fact or law. The Trustees shall not be
responsible or liable in any event for any neglect or wrongdoing of them or of
any officer, agent, employee, consultant, investment adviser or other adviser,
administrator, distributor or principal underwriter, custodian or transfer,
dividend disbursing, shareholder servicing or accounting agent of the Trust, nor
shall any Trustee be responsible for the act or omission of any other Trustee.
The Trustees may take advice of counsel or other experts with respect to the
meaning and operation of this Declaration and their duties as Trustees, and
shall be under no liability for any act or omission in accordance with such
advice or for failing to follow such advice. In discharging their duties, the
Trustees, when acting in good faith, shall be entitled to rely upon the records,
books and accounts of the Trust and upon reports made to the Trustees by any
officer, employee, agent, consultant, accountant, attorney, investment adviser
or other adviser, principal underwriter, expert, professional firm or
independent contractor. The Trustees as such shall not be required to give any
bond or surety or any other security for the performance of their duties. No
provision of this Declaration shall protect any Trustee or officer of the Trust
against any liability to the Trust or its Shareholders to which he would
otherwise be subject by reason of his own willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of his
office.



                                       10
<PAGE>




      SECTION 4.3. INDEMNIFICATION. The Trustees may provide, whether in the
By-Laws or by contract, vote or other action, for the indemnification by the
Trust or by any Class or Series thereof of the Shareholders, Trustees, officers
and employees of the Trust and of such other Persons as the Trustees in the
exercise of their discretion may deem appropriate or desirable. Any such
indemnification may be mandatory or permissive, and may be insured against by
policies maintained by the Trust.

      SECTION 4.4. NO DUTY OF INVESTIGATION. No purchaser, lender or other
Person dealing with the Trustees or any officer, employee or agent of the Trust
or a Class or Series thereof shall be bound to make any inquiry concerning the
validity of any transaction purporting to be made by the Trustees or by said
officer, employee or agent or be liable for the application of money or property
paid, loaned, or delivered to or on the order of the Trustees or of said
officer, employee or agent. Every obligation, contract, instrument, certificate,
Share, other security or undertaking of the Trust or a Class or Series, and
every other act or thing whatsoever executed in connection with the Trust shall
be conclusively presumed to have been executed or done by the executors thereof
only in their capacity as Trustees under this Declaration or in their capacity
as officers, employees or agents of the Trust. Every written obligation,
contract, instrument, certificate, Share, other security or undertaking of the
Trust or a Class or Series made or issued by the Trustees may recite that the
same is executed or made by them not individually, but as Trustees under the
Declaration, and that the obligations of the Trust or a Class or Series thereof
under any such instrument are not binding upon any of the Trustees or
Shareholders individually, but bind only the Trust Property or the Trust
Property of the applicable Class or Series, and may contain any further recital
which they may deem appropriate, but the omission of any such recital shall not
operate to bind the Trustees or Shareholders individually.

      SECTION 4.5. RELIANCE ON RECORDS AND EXPERTS. Each Trustee, officer or
employee of the Trust shall, in the performance of his duties, be fully and
completely justified and protected with regard to any act or any failure to act
resulting from reliance in good faith upon the records, books and accounts of
the Trust or a Class or Series thereof, upon an opinion or other advice of legal
counsel, or upon reports made or advice given to the Trust or a Class or Series
thereof by any Trustee or any of the Trust's officers or employees or by the
Investment Adviser, the Administrator, the Custodian, a Principal Underwriter,
Transfer Agent, accountants, appraisers or other experts, advisers, consultants
or professionals selected with reasonable care by the Trustees or officers of
the Trust, regardless of whether the person rendering such report or advice may
also be a Trustee, officer or employee of the Trust.

                                    ARTICLE V

                          SHARES OF BENEFICIAL INTEREST

      SECTION 5.1. SHARES OF BENEFICIAL INTEREST. The interest of the
beneficiaries of the Trust initially shall be divided into common shares of
beneficial interest of $.01 par value. The number of common shares authorized
hereunder is unlimited. All shares issued, including, without limitation, those
issued in connection with a dividend or distribution or a share split, shall be
fully paid and nonassessable. The Trustees may, without Shareholder approval,
authorize one or more Classes of Shares (which Classes may without Shareholder
approval be divided by the Trustees into two or more Series), Shares of each
such Class or Series having such preferences, voting powers and special or
relative rights or privileges (including conversion rights, if any) as the
Trustees may determine and as shall be set forth in a resolution adopted in
accordance with the By-Laws. The number of Shares of each Class or Series
authorized shall be unlimited except as the By-Laws may otherwise provide. The
Trustees may from time to time divide or combine the Shares of any Class or
Series into a greater or lesser number without thereby changing the
proportionate beneficial interest in the Class or Series.

      The ownership of Shares shall be recorded on the books of the Trust or a
transfer or similar agent. No certificates certifying the ownership of Shares
shall be issued except as the Trustees may otherwise determine from time to


                                       11
<PAGE>




time. The Trustees may make such rules as they consider appropriate for the
issuance of Share certificates, the transfer of Shares and similar matters. The
record books of the Trust as kept by the Trust or any transfer or similar agent,
as the case may be, shall be conclusive as to who are the Shareholders of each
Class or Series and as to the number of Shares of each Class or Series held from
time to time by each Shareholder. The Trustees may at any time discontinue the
issuance of Share certificates and may, by written notice to each Shareholder,
require the surrender of Share certificates to the Trust for cancellation. Such
surrender and cancellation shall not affect the ownership of Shares in the
Trust.

      SECTION 5.2. VOTING POWERS. Subject to the voting powers of one or more
Classes or Series, the Shareholders shall have power to vote only (i) with
respect to the election of Trustees, (ii) for the removal of Trustees as
provided for herein, (iii) with respect to any Investment Adviser as required by
applicable law, (iv) with respect to any termination or amendment of this Trust,
or with respect to certain transactions, to the extent and as provided in
Article VIII, (v) to the same extent as the stockholders of a Massachusetts
business corporation as to whether or not a court action, proceeding or claim
should or should not be brought or maintained derivatively or as a class action
on behalf of the Trust or the Shareholders, and (vi) with respect to such
additional matters relating to the Trust as may be required by law, this
Declaration, the By-Laws or any registration of the Trust with the Securities
and Exchange Commission (or any successor agency) or any state, or as the
Trustees may consider necessary or desirable. Each whole Share shall be entitled
to one vote as to any matter on which it is entitled to vote and each fractional
Share shall be entitled to a proportionate fractional vote. Notwithstanding any
other provision of this Declaration, on any matter submitted to a vote of
Shareholders, all Shares of the Trust then entitled to vote shall, except as
otherwise provided in the By-Laws or required by applicable law, be voted in the
aggregate as a single Class without regard to Classes or Series. There shall be
no cumulative voting in the election of Trustees.

      SECTION 5.3. RIGHTS OF SHAREHOLDERS. The ownership of the Trust Property
of every description and the right to conduct any business of the Trust are
vested exclusively in the Trustees, and the Shareholders shall have no interest
therein other than the beneficial interest conferred by their Shares, and they
shall have no right to call for any partition or division of any property,
profits, rights or interests of the Trust or of any Class or Series nor can they
be called upon to share or assume any losses of the Trust or of any Class or
Series or suffer an assessment of any kind by virtue of their ownership of
Shares. The Shares shall be personal property giving only the rights
specifically set forth in this Declaration. The Shares shall not entitle the
holder to preference, preemptive, appraisal, conversion or exchange rights,
except as the Trustees may specifically determine with respect to any Class or
Series.

      Every Shareholder by virtue of having become a Shareholder shall be held
to have expressly assented and agreed to the terms of this Declaration and the
Bylaws and to have become a party hereto and thereto. The death of a Shareholder
during the continuance of the Trust shall not operate to terminate the same nor
entitle the representative of any deceased Shareholder to an accounting or to
take any action in court or elsewhere against the Trust or the Trustees, but
only to the rights of said decedent under this Trust.

      SECTION 5.4. TRUST ONLY. It is the intention of the Trustees to create
only the relationship of Trustee and beneficiary between the Trustees and each
Shareholder from time to time. It is not the intention of the Trustees to create
a general partnership, limited partnership, joint stock association,
corporation, bailment or any form of legal relationship other than a
Massachusetts business trust. Nothing in this Declaration shall be construed to
make the Shareholders, either by themselves or with the Trustees, partners or
members of a joint stock association.

      SECTION 5.5. ISSUANCE OF SHARES. The Trustees in their discretion may,
from time to time and without any authorization or vote of the Shareholders,
issue Shares of any Class or Series, in addition to the then issued and
Outstanding Shares, to such party or parties and for such amount and type of
consideration, including cash or property, at such time or times and on such


                                       12
<PAGE>




terms as the Trustees may deem appropriate or desirable, and may in such manner
acquire other assets (including the acquisition of assets subject to, and in
connection with the assumption of, liabilities) and businesses. In connection
with any issuance of Shares, the Trustees may issue fractional Shares and
reissue and resell full and fractional Shares held in the treasury. The Trustees
may authorize the issuance of certificates of beneficial interest to evidence
the ownership of Shares. Shares held in the treasury shall not be voted nor
shall such Shares be entitled to any dividends or other distributions declared
with respect thereto. The Trustees in their discretion may also, from time to
time and without any authorization or vote of the Shareholders, issue to the
extent consistent with applicable law securities of the Trust convertible into
Shares of the Trust and warrants to purchase securities of the Trust, in each
case pursuant to such terms and under such conditions as the Trustees may
specify in their discretion. Shares of any Class or Series, in addition to the
then issued and outstanding Shares, and such warrants or convertible securities,
may be issued to such party or parties and for such amount and type of
consideration, including cash or property, at such time or times and on such
terms as the Trustees may deem appropriate or desirable, and may in such manner
acquire other assets (including the acquisition of assets subject to, and in
connection with the assumption of, liabilities) and businesses. The officers of
the Trust are severally authorized to take all such actions as may be necessary
or desirable to carry out this Section 5.5.


                                   ARTICLE VI

                           REDEMPTIONS AND REPURCHASES

      SECTION 6.1. REDEMPTIONS AND REPURCHASES OF SHARES. From time to time the
Trust may redeem or repurchase its Shares, all upon such terms and conditions as
may be determined by the Trustees and subject to any applicable provisions of
the 1940 Act. The Trust may require Shareholders to pay a withdrawal charge, a
sales charge, or any other form of charge to the Trust, to the underwriter or to
any other person designated by the Trustees upon redemption or repurchase of
Trust Shares in such amount as shall be determined from time to time by the
Trustees. The Trust may also charge a redemption or repurchase fee in such
amount as may be determined from time to time by the Trustees.

      SECTION 6.2 MANNER OF PAYMENT. Payment of Shares redeemed or repurchased
may at the option of the Trustees or such officer or officers as they may duly
authorize for the purpose, in their complete discretion, be made in cash, or in
kind, or partially in cash and partially in kind. In case of payment in kind the
Trustees, or their delegate, shall have absolute discretion as to what security
or securities shall be distributed in kind and the amount of the same, and the
securities shall be valued for purposes of distribution at the figure at which
they were appraised in computing the net asset value of the Shares, provided
that any Shareholder who cannot legally acquire securities so distributed in
kind by reason of the prohibitions of the 1940 Act shall receive cash.

      SECTION 6.3. INVOLUNTARY REDEMPTION. If the Trustees shall, at any time
and in good faith, be of the opinion that direct or indirect ownership of Shares
of any Class or Series or other securities of the Trust has or may become
concentrated in any person to an extent which would disqualify the Trust as a
regulated investment company under the Internal Revenue Code, then the Trustees
shall have the power by lot or other means deemed equitable by them (i) to call
for redemption by any such person a number, or principal amount, of Shares or
other securities of the Trust sufficient to maintain or bring the direct or
indirect ownership of Shares or other securities of the Trust into conformity
with the requirements for such qualification and (ii) to refuse to transfer or
issue Shares or other securities of the Trust to any person whose acquisition of
the Shares or other securities of the Trust in question would result in such
disqualification. The redemption shall be effected upon such terms and
conditions as shall be determined by the Trustees.



                                       13
<PAGE>




      The holders of Shares or other securities of the Trust shall upon demand
disclose to the Trustees in writing such information with respect to direct and
indirect ownership of Shares or other securities of the Trust as the Trustees
deem necessary to comply with the provisions of the Internal Revenue Code, or to
comply with the requirements of any other taxing authority.


                                   ARTICLE VII

                        DETERMINATION OF NET ASSET VALUE,
                          NET INCOME AND DISTRIBUTIONS

      SECTION 7.1. NET ASSET VALUE. The net asset value of each outstanding
Share of the Trust or of any Class or Series thereof shall be determined on such
days and at or as of such time or times as the Trustees may determine. Any
reference in this Declaration to the time at which a determination of net asset
value is made shall mean the time as of which the determination is made. The
power and duty to determine and method of determination of net asset value may
be delegated by the Trustees from time to time to the Investment Adviser, the
Administrator, the Custodian, the Transfer Agent or such other Person or Persons
as the Trustees may determine. The value of the assets of the Trust or any Class
or Series thereof shall be determined in a manner authorized by the Trustees.
From the total value of said assets, there shall be deducted all indebtedness,
interest, taxes, payable or accrued, including estimated taxes on unrealized
book profits, expenses and management charges accrued to the appraisal date, and
all other items in the nature of liabilities which shall be deemed appropriate
by the Trustees, as incurred by or allocated to the Trust or any Class or Series
thereof. The resulting amount, which shall represent the total net assets of the
Trust or Class or Series thereof, shall be divided by the number of Outstanding
Shares of the Trust or Class or Series thereof at that time and the quotient so
obtained shall be deemed to be the net asset value of the Shares of the Trust or
Class or Series thereof. The Trust may declare a suspension of the determination
of net asset value to the extent permitted by the 1940 Act. It shall not be a
violation of any provision of this Declaration if Shares are sold, redeemed or
repurchased by the Trust at a price other than one based on net asset value if
the net asset value is affected by one or more errors inadvertently made in the
pricing of portfolio securities or other investments or in accruing or
allocating income, expenses, reserves or liabilities. No provision of this
Declaration shall be construed to restrict or affect the right or ability of the
Trust to employ or authorize the use of pricing services, appraisers or any
other means, methods, procedures, or techniques in valuing the assets or
calculating the liabilities of the Trust or any Class or Series thereof.

      SECTION 7.2. DIVIDENDS AND DISTRIBUTIONS. (a) The Trustees may from time
to time distribute ratably among the Shareholders of the Trust or of a Class or
Series thereof such portion of the net earnings or profits, surplus (including
paid-in surplus), capital (including paid-in capital), or assets of the Trust or
such Class or Series held by the Trustees as they may deem appropriate or
desirable. Such distributions may be made in cash, additional Shares or property
(including without limitation any type of obligations of the Trust or Class or
Series or any assets thereof), and the Trustees may distribute ratably among the
Shareholders of the Trust or Class or Series thereof additional Shares of the
Trust or Class or Series thereof issuable hereunder in such manner, at such
times, and on such terms as the Trustees may deem appropriate or desirable. Such
distributions may be among the Shareholders of the Trust or Class or Series
thereof at the time of declaring a distribution or among the Shareholders of the
Trust or Class or Series thereof at such other date or time or dates or times as
the Trustees shall determine. The Trustees may always retain from the earnings
or profits such amounts as they may deem appropriate or desirable to pay the
expenses and liabilities of the Trust or a Class or Series thereof or to meet
obligations of the Trust or a Class or Series thereof, together with such
amounts as they may deem desirable to use in the conduct of its affairs or to
retain for future requirements or extensions of the business or operations of
the Trust or such Class or Series. The Trust may adopt and offer to Shareholders
such dividend reinvestment plans, cash dividend payout plans or other
distribution plans as the Trustees may deem appropriate or desirable. The


                                       14
<PAGE>




Trustees may in their discretion determine that an account administration fee or
other similar charge may be deducted directly from the income and other
distributions paid on Shares to a Shareholder's account in any Class or Series.

      (b) The Trustees may prescribe, in their absolute discretion, such bases
and times for determining the amounts for the declaration and payment of
dividends and distributions as they may deem necessary, appropriate or
desirable.

      (c) Inasmuch as the computation of net income and gains for federal income
tax purposes may vary from the computation thereof on the books of account, the
above provisions shall be interpreted to give the Trustees full power and
authority in their absolute discretion to distribute for any fiscal year as
dividends and as capital gains distributions, respectively, additional amounts
sufficient to enable the Trust or a Class or Series thereof to avoid or reduce
liability for taxes.

      SECTION 7.3. POWER TO MODIFY FOREGOING PROCEDURES. Notwithstanding any
provision contained in this Declaration, the Trustees may prescribe, in their
absolute discretion, such other means, methods, procedures or techniques for
determining the per Share net asset value of a Class or Series thereof or the
income of the Class or Series thereof, or for the declaration and payment of
dividends and distributions on any Class or Series.


                                  ARTICLE VIII

                       DURATION; TERMINATION OF TRUST OR A
                      CLASS OR SERIES; MERGERS; AMENDMENTS

      SECTION 8.1. DURATION. The Trust shall continue without limitation of time
but subject to the provisions of this Article VIII. The death, declination,
resignation, retirement, removal or incapacity of the Trustees, or any one of
them, shall not operate to terminate or annul the Trust or to revoke any
existing agency or delegation or authority pursuant to the terms of this
Declaration or of the By-Laws.

      SECTION 8.2. MERGER OR TERMINATION OF THE TRUST OR A SERIES OR A Class.
The Trust may merge or consolidate with any other corporation, association,
trust or other organization or may sell, lease or exchange all or substantially
all of the Trust property, including its good will, upon such terms and
conditions and for such consideration when and as authorized at a meeting of
Shareholders called for the purpose by the affirmative vote of the holders of
two-thirds of each Class and Series of Shares outstanding and entitled to vote
(with each such class and series separately voting thereon as a separate Class
or Series), or by an instrument or instruments in writing without a meeting,
consented to by the holders of two-thirds of each Class and Series of Shares
(with each such Class and Series separately consenting thereto as a separate
Class or Series); provided, however, that if such merger, consolidation, sale,
lease or exchange is recommended by the Trustees, the vote or written consent of
the holders of a majority of the Shares outstanding and entitled to vote shall
be sufficient authorization; and any such merger, consolidation, sale, lease or
exchange shall be deemed for all purposes to have been accomplished under and
pursuant to the statutes of the Commonwealth of Massachusetts. Upon making
provision for the payment of all outstanding obligations, taxes and other
liabilities, (whether accrued or contingent) of the Trust, the Trustees shall
distribute the remaining assets of the Trust ratably among the holders of the
outstanding Shares, except as may be otherwise provided by the Trustees with
respect to any Class or Series of Shares thereof.

      Subject to authorization by the Shareholders as indicated below in this
paragraph, the Trust may at any time sell and convert into money all of the
assets of the Trust, and, upon making provision for the payment of all
outstanding obligations, taxes and other liabilities (whether accrued or
contingent) of the Trust, the Trustees shall distribute the remaining assets of
the Trust ratably among the holders of the outstanding Shares, except as may be
otherwise provided by the Trustees with respect to any Class or Series of


                                       15
<PAGE>




Shares. Such action shall first have been authorized at a meeting of
Shareholders called for the purpose by the affirmative vote of the holders of
two-thirds of each Class and Series of Shares outstanding and entitled to vote
(with each such Class and Series separately voting thereon as a separate Class
or Series), or by an instrument or instruments in writing without a meeting,
consented to by the holders of two-thirds of each Class and Series of Shares
(with each such Class and Series separately consenting thereto as a separate
Class or Series); provided, however, that if such action is recommended by the
Trustees, the vote or written consent of the holders of a majority of the Shares
outstanding and entitled to vote shall be sufficient authorization.

      Upon completion of the distribution of the remaining proceeds or the
remaining assets as provided in this section, the Trust shall terminate and the
Trustees shall be discharged of any and all further liabilities and duties
hereunder and the right, title and interest of all parties shall be cancelled
and discharged.

      SECTION 8.3. AMENDMENTS. The execution of an instrument setting forth the
establishment and designation and the relative rights of any Class or Series of
Shares in accordance with Section 5.1 hereof shall, without any authorization,
consent or vote of the Shareholders, effect an amendment of this Declaration.
Except as otherwise provided in this Section, if authorized by a majority of the
Trustees and by vote of a majority of the outstanding voting securities of the
Trust affected by the amendment (which voting securities shall, unless otherwise
provided by the Trustees, vote together on such amendment as a single class), or
by any larger vote which may be required by applicable law or this Declaration
of Trust in any particular case, the Trustees may amend or otherwise supplement
this Declaration. The Trustees may also amend this Declaration without the vote
or consent of Shareholders to change the name of the Trust or to make such other
changes as do not have a materially adverse effect on the rights or interests of
Shareholders hereunder or if they deem it necessary to conform this Declaration
to the requirements of applicable Federal laws or regulations or the
requirements of the regulated investment company provisions of the Internal
Revenue Code, but the Trustees shall not be liable for failing so to do.

      No amendment may be made under this Section which shall amend, alter,
change or repeal any of the provisions of Article VIII unless the amendment
effecting such amendment, alteration, change or repeal shall receive the
affirmative vote or consent of the holders of two-thirds of each Class and
Series of Shares outstanding and entitled to vote (with each such Class and
Series separately voting thereon on consenting thereto as a separate Class or
Series). Such affirmative vote or consent shall be in addition to the vote or
consent of the holders of Shares otherwise required by law or by any agreement
between the Trust and any national securities exchange.

      Nothing contained in this Declaration shall permit the amendment of this
Declaration to impair the exemption from personal liability of the Shareholders,
Trustees, officers, employees and agents of the Trust or to permit assessments
upon Shareholders.

      Notwithstanding any other provision hereof, until such time as a
Registration Statement under the Securities Act of 1933, as amended, covering
the first public offering of securities of the Trust shall have become
effective, this Declaration may be terminated or amended in any respect by the
affirmative vote of a majority of the Trustees or by an instrument signed by a
majority of the Trustees.

      SECTION 8.4. CERTAIN TRANSACTIONS. (a) Notwithstanding any other provision
of this Declaration and subject to the exceptions provided in sub-section (d) of
this Section 8.4, the types of transactions described in sub-section (c) of this
Section 8.4 shall require the affirmative vote or consent of the holders of
seventy-five percent (75%) of each Class of Shares outstanding (with each such
Class voting separately thereon), when a Principal Shareholder (as defined in
sub-section (b) of this Section 8.4) is determined by the Trustees to be a party
to the transaction. Such affirmative vote or consent shall be in addition to the


                                       16
<PAGE>




vote or consent of the holders of Shares otherwise required by law or by the
terms of any Class or Series, whether now or hereafter authorized, or by any
agreement between the Trust and any national securities exchange.

      (b) The term "Principal Shareholder" shall mean any Person which is the
beneficial owner, directly or indirectly, of more than five percent (5%) of the
Outstanding Shares of the Trust or of any Class and shall include any
"affiliate" or "associate", as such terms are defined in Rule 12b-2 of the
General Rules and Regulations under the Securities Exchange Act of 1934. For the
purpose of this Section 8.4, in addition to the Shares which a Person
beneficially owns directly, (a) a Person shall be deemed to be the beneficial
owner of any Shares (i) which the Trustees determine it has the right to acquire
pursuant to any agreement or upon exercise of conversion rights or warrants, or
otherwise (but excluding Share options granted by the Trust) or (ii) which the
Trustees determine are beneficially owned, directly or indirectly (including
Shares deemed owned through application of clause (i) above), by any other
Person with which it or its "affiliate" or "associate" (as defined above) has
any agreement, arrangement or understanding for the purpose of acquiring,
holding, voting or disposing of Shares, or which is its affiliate or associate,
and (b) the outstanding Shares shall include Shares deemed owned through
application of clauses (i) and (ii) above but shall not include any other Shares
which are not at the time issued and outstanding but may be issuable pursuant to
any agreement, or upon exercise of conversion rights or warrants, or otherwise.

      (c) This Section 8.4 shall apply to the following transactions:

            (i) The merger or consolidation of the Trust or any subsidiary of
            the Trust with or into any Principal Shareholder.

            (ii) The issuance of any securities of the Trust to any Principal
            Shareholder for cash.

            (iii) The sale, lease or exchange of all or any substantial part of
            the assets of the Trust to any Principal Shareholder (except assets
            determined by the Trustees to have an aggregate fair market value of
            less than $1,000,000, aggregating for the purpose of such
            computation all assets sold, leased or exchanged in any series of
            similar transactions within a twelve-month period or assets sold in
            the ordinary course of business).

            (iv) The sale, lease or exchange to or with the Trust or any
            subsidiary thereof, in exchange for securities of the Trust, of any
            assets of any Principal Shareholder (except assets determined by the
            Trustees to have an aggregate fair market value of less than
            $1,000,000 aggregating for the purpose of such computation all
            assets sold, leased or exchanged in any series of similar
            transactions within a twelve-month period).

      For purposes of this sub-section 8.4(c), the term "Principal Shareholder"
shall include all subsidiaries, affiliates, associates, or other persons acting
in concert with any Principal Shareholder.

      (d) The provisions of this Section 8.4 shall not be applicable to (i) any
of the transactions described in sub-section (c) of this Section 8.4 if the
Trustees shall by resolution have approved a memorandum of understanding with
such Principal Shareholder with respect to and substantially consistent with
such transaction, or (ii) any such transaction with any Person of which a
majority of the outstanding shares of all classes of stock normally entitled to
vote in the election of directors is owned of record or beneficially by the
Trust and its subsidiaries.

      (e) The Trustees shall have the power to determine for the purposes of
this Section 8.4 on the basis of information known to the Trust, whether (i) a
Person beneficially owns more than five percent (5%) of the outstanding Shares
or is otherwise a Principal Shareholder, (ii) a Person is an "affiliate" or
"associate" (as defined above) of another, (iii) the assets being acquired or
leased to or by the Trust or any subsidiary thereof constitute a substantial


                                       17
<PAGE>




part or the assets of the Trust and have an aggregate fair market value of less
than $1,000,000, (iv) the memorandum of understanding referred to in sub-section
(d) hereof is substantially consistent with the transaction covered thereby, and
(v) the provisions of the Section 8.5 otherwise apply to any Person or
transaction. Any such determination shall be conclusive and binding for all
purposes of this Section 8.4.

      SECTION 8.5. CONVERSION. Notwithstanding any other provisions of this
Declaration, the conversion of the Trust from a "closed-end company" to an
"open-end company," as those terms are defined in Section 5(a)(2) and 5(a)(1),
respectively, of the 1940 Act shall require the affirmative vote or consent of
the holders of two-thirds of each Class outstanding (with each Class separately
voting thereon or consenting thereto as a separate Class). Such affirmative vote
or consent shall be in addition to the vote or consent of the holders of the
Shares otherwise required by law or by the terms of any Class or Series, whether
now or hereafter authorized, or by any agreement between the Trust and any
national securities exchange. However, if such conversion is recommended by at
least 75% of the Trustees then in office, the vote or written consent of the
holders of a majority of the outstanding voting securities of the Trust (which
voting securities shall vote separately on the matter by class) shall be
sufficient to authorize such conversion.


                                   ARTICLE IX

                                  MISCELLANEOUS

      SECTION 9.1. USE OF THE WORDS "EATON VANCE". Eaton Vance Corp.
(hereinafter referred to as "EVC"), which owns (either directly or through
subsidiaries) all of the capital shares of the Investment Adviser of the Trust
(or of the investment adviser of each of the investment companies referred to in
the last paragraph of Section 2.3), has consented to the use by the Trust of the
identifying words "Eaton Vance" in the name of the Trust. Such consent is
conditioned upon the continued employment of EVC or a subsidiary or affiliate of
EVC as Investment Adviser of the Trust or as the investment adviser of each of
the investment companies referred to in the last paragraph of Section 2.3. As
between the Trust and itself, EVC shall control the use of the name of the Trust
insofar as such name contains the identifying words "Eaton Vance". EVC may from
time to time use the identifying words "Eaton Vance" in other connections and
for other purposes, including, without limitation, the names of other investment
companies, trusts, corporations or businesses which it may manage, advise,
sponsor or own or in which it may have a financial interest. EVC may require the
Trust to cease using the identifying words "Eaton Vance" in the name of the
Trust if EVC or a subsidiary or affiliate of EVC ceases to act as investment
adviser of the Trust or as the investment adviser of each of the investment
companies referred to in the last paragraph of Section 2.3.

      SECTION 9.2. NOTICES. Notwithstanding any other provision of this
Declaration, any and all notices to which any Shareholder may be entitled and
any and all communications shall be deemed duly served or given if mailed,
postage prepaid, addressed to any Shareholder of record at his last known
address as recorded on the register of the Trust. If and to the extent
consistent with applicable law, a notice of a meeting, an annual report, and any
other communication to Shareholders need not be sent to a Shareholder (i) if an
annual report and a proxy statement for two consecutive shareholder meetings
have been mailed to such Shareholder's address and have been returned as
undeliverable, (ii) if all, and at least two, checks (if sent by first class
mail) in payment of distributions on Shares during a twelve-month period have
been mailed to such Shareholder's address and have been returned as
undeliverable or (iii) in any other case in which a proxy statement concerning a
meeting of security holders is not required to be given pursuant to the
Commission's proxy rules as from time to time in effect under the Securities
Exchange Act of 1934, as amended. However, delivery of such proxy statements,
annual reports and other communications shall resume if and when such
Shareholder delivers or causes to be delivered to the Trust written notice
setting forth such Shareholder's then current address.

      SECTION 9.3. FILING OF COPIES, REFERENCES, HEADINGS AND COUNTERPARTS. The
original or a copy of this instrument, of any amendment hereto and of each
declaration of trust supplemental hereto, shall be kept at the office of the
Trust. Anyone dealing with the Trust may rely on a certificate by a Trustee or
an officer of the Trust as to whether or not any such amendments or supplemental
declarations of trust have been made and as to any matters in connection with
the Trust hereunder, and, with the same effect as if it were the original, may
rely on a copy certified by a Trustee or an officer of the Trust to be a copy of
this instrument or of any such amendment hereto or supplemental declaration of
trust.

      In this instrument or in any such amendment or supplemental declaration of
trust, references to this instrument, and all expressions such as "herein",
"hereof", and "hereunder", shall be deemed to refer to this instrument as
amended or affected by any such supplemental declaration of trust. Headings are
placed herein for convenience of reference only and in case of any conflict, the
text of this instrument, rather than the headings, shall control. This
instrument may be executed in any number of counterparts each of which shall be
deemed an original, but such counterparts shall constitute one instrument. A
restated Declaration, integrating into a single instrument all of the provisions
of the Declaration which are then in effect and operative, may be executed from
time to time by a majority of the Trustees then in office and filed with the
Massachusetts Secretary of State. A restated Declaration shall, upon execution,
be conclusive evidence of all amendments and supplemental declarations contained
therein and may thereafter be referred to in lieu of the original Declaration
and the various amendments and supplements thereto.

      SECTION 9.4. APPLICABLE LAW. The Trust set forth in this instrument is
made in The Commonwealth of Massachusetts, and it is created under and is to be
governed by and construed and administered according to the laws of said
Commonwealth. The Trust shall be of the type commonly called a Massachusetts
business trust, and without limiting the provisions hereof, the Trust may
exercise all powers which are ordinarily exercised by such a trust.

      SECTION 9.5. PROVISIONS IN CONFLICT WITH LAW OR REGULATIONS. (a) The
provisions of this Declaration are severable, and if the Trustees shall
determine, with the advice of legal counsel, that any of such provisions is in
conflict with the 1940 Act, the Internal Revenue Code of 1986 or with other
applicable laws and regulations, the conflicting provision shall be construed in
such a manner consistent with such law as may most closely reflect the intention
of the offending provision; provided, however, that such determination shall not
affect any of the remaining provisions of this Declaration or render invalid or
improper any action taken or omitted prior to such determination.

      (b) If any provision of this Declaration shall be held invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall
attach only to such provision in such jurisdiction and shall not in any manner
affect such provision in any other jurisdiction or any other provision of this
Declaration in any jurisdiction.

of the foregoing,  the Trustees may appoint a committee  consisting of less than

act for and bind the  Trustees and the Trust,  as if the acts of such  committee
were  the  acts  of all  the  Trustees  then  in  office,  with  respect  to the
institution,  prosecution, dismissal, settlement, review, investigation or other

meetings of the  shareholders  and of the Trustees.  He may call meetings of the
Trustees and of any committee  thereof whenever he deems it necessary.  He shall

general supervision over the business and policies of this Trust, subject to the
limitations imposed upon the President, as provided in Section 4 of this Article
III.

SECTION 4.  PRESIDENT.  In the  absence of the  Chairman  of the  Trustees,  the
President  shall  preside at all  meetings of the  shareholders.  Subject to the
Trustees and to any committees of the Trustees, within their respective spheres,
as  provided  by  the  Trustees,  he  shall  at all  times  exercise  a  general
supervision and direction over the affairs of the Trust. He shall have the power
to employ  attorneys  and counsel  for the Trust and to employ such  subordinate
officers,  agents, clerks and employees as he may find necessary to transact the
business of the Trust. He shall also have the power to grant, issue,  execute or
sign such  powers  of  attorney,  proxies  or other  documents  as may be deemed
advisable  or  necessary  in  furtherance  of the  interests  of the Trust.  The
President  shall have such other powers and duties as, from time to time, may be
conferred upon or assigned to him by the Trustees.

SECTION  5.  TREASURER.  The  Treasurer  shall be the  principal  financial  and
accounting  officer of the Trust.  He shall deliver all funds and  securities of
the Trust  which may come  into his hands to such bank or trust  company  as the
Trustees  shall  employ as  custodian  in  accordance  with  Article  III of the
Declaration  of Trust.  He shall make annual  reports in writing of the business
conditions of the Trust, which reports shall be preserved upon its records,  and

Trustees may from time to time require.  The Treasurer shall perform such duties
additional to foregoing as the Trustees may from time to time designate.

all  votes  and  proceedings  of the  Trustees  and the  shareholders  at  their
respective meetings. He shall have custody of the seal, if any, of the Trust and

                                   ARTICLE IV

                            Meetings of Shareholders

SECTION 1. MEETINGS.  Meetings of shareholders,  at which the shareholders shall
elect  Trustees and transact such other business as may properly come before the
meeting,  shall be held  annually  so long as  required  by the New  York  Stock
Exchange  or  such  other  exchange  or  trading  system  on  which  shares  are
principally traded. Meetings of the shareholders (or any class or series) may be
called at any time by the President, and shall be called by the President or the
Secretary  at the  request,  in writing or by  resolution,  of a majority of the
Trustees,  or at the  written  request of the  holder or holders of  twenty-five
percent  (25%) or more of the total  number of the then  issued and  outstanding
shares of the Trust  entitled to vote at such  meeting.  Any such request  shall
state the purposes of the proposed meeting.

SECTION 2. PLACE OF MEETINGS.  Meetings of the shareholders shall be held at the
principal  place of  business  of the Trust in Boston,  Massachusetts,  unless a
different  place  within the United  States is  designated  by the  Trustees and
stated as specified in the respective  notices or waivers of notice with respect
thereto.

SECTION 3.  NOTICE OF  MEETINGS.  Notice of all  meetings  of the  shareholders,
stating the time,  place and the  purposes  for which the  meetings  are called,
shall be given by the  Secretary to each  shareholder  entitled to vote thereat,
and to each  shareholder  who under the By-Laws is entitled to such  notice,  by
mailing the same  postage  paid,  addressed  to him at his address as it appears
upon the books of the  Trust,  at least ten (10) days no more than  ninety  (90)
days  before the time fixed for the  meeting,  and the person  given such notice
shall make an affidavit  with respect  thereto.  If any  shareholder  shall have
failed to inform the Trust of his post office address, no notice need be sent to
him. No notice need be given to any  shareholder  if a written waiver of notice,
executed  before  or  after  the  meeting  by the  shareholder  or his  attorney
thereunto authorized, is filed with the records of the meeting.

SECTION 4. QUORUM.  Except as otherwise  provided by law, to constitute a quorum
for the transaction of any business at any meeting of  shareholders,  there must
be present, in person or by proxy,  holders of a majority of the total number of
shares of the then issued and  outstanding  shares of the Trust entitled to vote
at such  meeting;  provided that if a class (or series) of shares is entitled to
vote as a separate  class (or  series) on any  matter,  then in the case of that
matter a quorum  shall  consist of the holders of a majority of the total number
of shares of the then  issued and  outstanding  shares of that class (or series)
entitled to vote at the meeting.  Shared  owned  directly or  indirectly  by the
Trust, if any, shall not be deemed outstanding for this purpose.

      If a quorum, as above defined, shall not be present for the purpose of any
vote that may properly come before any meeting of  shareholders  at the time and
place of any  meeting,  the  shareholders  present  in  person  or by proxy  and
entitled to vote at such meeting on such matter holding a majority of the shares
present and entitled to vote on such matter may by vote adjourn the meeting from
time to  time  to be held at the  same  place  without  further  notice  than by
announcement  to be given  at the  meeting  until a  quorum,  as above  defined,


                                      -3-
<PAGE>

entitled to vote on such matter, shall be present, whereupon any such matter may
be voted upon at the meeting as though held when originally convened.

SECTION 5. VOTING. At each meeting of the shareholders  every shareholder of the
Trust  shall be  entitled  to one (1) vote in person or by proxy for each of the
then  issued and  outstanding  shares of the Trust then having  voting  power in
respect of the matter  upon which the vote is to be taken,  standing in his name
on the books of the Trust at the time of the closing of the  transfer  books for
the meeting,  or, if the books be not closed for any meeting, on the record date
fixed as  provided in Section 4 of Article VI of these  By-Laws for  determining
the shareholders entitled to vote at such meeting, or if the books be not closed
and no record date be fixed, at the time of the meeting.  The record holder of a
fraction of a share shall be entitled in like manner to  corresponding  fraction
of a vote.  Notwithstanding the foregoing,  the Trustees may, in connection with
the  establishment  of any class (or series) of shares or in proxy materials for
any meeting of  shareholders  or in other  solicitation  materials or by vote or
other action duly taken by them,  establish  conditions  under which the several
classes (or series) shall have separate voting rights or no voting rights.

      All elections of Trustees shall be conducted in any manner approved at the
meeting of the  shareholders  at which said  election  is held,  and shall be by
ballot if so requested by any shareholder  entitled to vote thereon. The persons
receiving  the greatest  number of votes shall be deemed and  declared  elected.
Except as otherwise  required by law or by the  Declaration of Trust or by these
By-Laws,  all  matters  shall be  decided by a majority  of the votes  cast,  as
hereinabove provided, by persons entitled to vote thereon.

SECTION 6.  PROXIES.  Any  shareholder  entitled  to vote upon any matter at any
meeting  of the  shareholders  may so vote by proxy.  A proxy may be in  writing
subscribed by the shareholder or by his duly authorized  representatives,  agent
or  attorney.  A written  proxy  shall be dated;  if an  undated  written  proxy
solicited by the  management of the Trust is delivered to the Trust or its agent
or  representative,  such proxy shall be deemed dated by the  shareholder on the
date of its receipt by the Trust or its agent or representative. A written proxy
need not be sealed, witnessed or acknowledged.  A written proxy may be delivered
to the Trust or its agent by facsimile machine,  graphic communication equipment
or similar  electronic  transmission.  The  shareholder  may also  authorize and
empower the persons named as proxies,  representatives,  agents or attorneys (or
their  duly  appointed  substitutes),  or any one of them on any  form of  proxy
solicited by the  management  of the Trust to vote all shares of the Trust which
he is  entitled to vote upon any matter at any  meeting of the  shareholders  by
recording his voting  instructions  on any recording  device  maintained for the
purpose by the Trust or its agent or representative;  such recorded instructions
shall be deemed to constitute a written proxy  subscribed by the shareholder and
delivered by him to the Trust or its agent or representative and shall be deemed
to be  dated  as of  the  date  such  instructions  were  transmitted,  and  the
shareholder  shall be deemed to have  approved and ratified all actions taken by
such persons in accordance with the voting  instructions  so recorded.  No proxy
which is dated (or deemed dated) more than six months before the initial session
of the  meeting  shall be  accepted  and no such proxy  shall be valid after the
final  adjournment  of the meeting.  A proxy  solicited by the management of the
Trust  purporting to be executed or transmitted by or on behalf of a shareholder
shall be valid unless  challenged at or prior to exercise of the proxy,  and the
burden of proving  any  invalidity  shall be borne by the person  asserting  the
challenge.  A proxy  solicited  by the  management  of the Trust with respect to
shares  held in the name of two or more  persons  shall be valid if  executed or
transmitted by one of them unless at or prior to its exercise the Trust receives
a specific written notice to the contrary from any one of them.

SECTION 7. CONSENTS.  Any action which may be taken by shareholders may be taken
without a meeting if a majority of  shareholders  entitled to vote on the matter
(or such larger proportion  thereof as shall be required by law, the Declaration


                                      -4-
<PAGE>

or these  By-Laws for approval of such matter)  consent to the action in writing
and the  written  consents  are  filed  with  the  records  of the  meetings  of
shareholders. Such consents shall be treated for all purposes as a vote taken at
a meeting of shareholders.


                                    ARTICLE V

                                Trustees Meetings

SECTION 1. MEETINGS. The Trustees may in their discretion provide for regular or
stated meetings of the Trustees.  Meetings of the Trustees other than regular or
stated meetings shall be held whenever  called by the Chairman,  President or by
any other  Trustee at the time being in office.  Any or all of the  Trustees may
participate  in  a  meeting  by  means  of a  conference  telephone  or  similar
communications  equipment  by means of which all  persons  participating  in the
meeting can hear each other at the same time,  and  participation  by such means
shall constitute presence in person at a meeting.

SECTION 2.  NOTICES.  Notice of regular  or stated  meetings  need not be given.
Notice  of the time and  place of each  meeting  other  than  regular  or stated
meeting  shall be given by the  Secretary or by the Trustee  calling the meeting
and shall be mailed to each Trustee at least two (2) days before the meeting, or
shall be  telegraphed,  cabled,  or  wirelessed  to each Trustee at his business
address or personally  delivered to him at least one (1) day before the meeting.
Such notice may,  however,  be waived by all the  Trustees.  Notice of a meeting
need not be given to any Trustee if a written waiver of notice,  executed by him
before or after the meeting, is filed with the records of the meeting, or to any
Trustee  who  attends the meeting  without  protesting  prior  thereto or at its
commencement  the lack of notice to him.  A notice or waiver of notice  need not
specify the purpose of any special meeting.

SECTION 3. CONSENTS. Any action required or permitted to be taken at any meeting
of the  Trustees  may be taken by the  Trustees  without a meeting  if a written
consent  thereto is signed by all the Trustees and filed with the records of the
Trustees' meetings.  A Trustee may deliver his consent to the Trust by facsimile
machine or other graphic communication equipment.  Such consent shall be treated
as a vote at a meeting for all purposes.

SECTION 4. PLACE OF  MEETINGS.  The Trustees  may hold their  meetings  within
or without the Commonwealth of Massachusetts.

SECTION 5.  QUORUM AND MANNER OF ACTING.  A majority  of the  Trustees in office
shall be  present  in person at any  regular  stated or  special  meeting of the
Trustees in order to constitute a quorum for the transaction of business at such
meeting and (except as otherwise  required by the Declaration of Trust, by these
By-Laws or by statute) the act of a majority of the Trustees present at any such
meeting, at which a quorum is present,  shall be the act of the Trustees. In the
absence of quorum,  a majority of the  Trustees  present may adjourn the meeting
from time to time  until a quorum  shall be  present.  Notice  of any  adjourned
meeting need not be given.

                                   ARTICLE VI

                          Shares of Beneficial Interest

SECTION 1.  CERTIFICATES  FOR SHARES OF BENEFICIAL  INTEREST.  Certificates  for
shares of  beneficial  interest of any class of shares of the Trust,  if issued,
shall be in such form as shall be approved by the Trustees. They shall be signed
by, or in the name of, the Trust by the  President and by the Treasurer and may,
but need not be, sealed with seal of the Trust;  provided,  however,  that where
such  certificate  is signed by a transfer  agent or a transfer  clerk acting on
behalf of the Trust or a registrar other than a Trustee,  officer or employee of
the Trust,  the  signature of the  President  or  Treasurer  and the seal may be
facsimile.  In case any  officer or  officers  who shall have  signed,  or whose
facsimile  signature or signatures  shall have been used on any such certificate
or certificates, shall cease to be such officer or officers of the Trust whether
because  of  death,  resignation  or  otherwise,   before  such  certificate  or
certificates  shall  have been  delivered  by the  Trust,  such  certificate  or
certificates  may  nevertheless  be  adopted  by the  Trust  and be  issued  and
delivered  as though the  person or  persons  who  signed  such  certificate  or
certificates or whose facsimile  signatures shall have been used thereon had not
ceased to be such officer or officers of the Trust.

SECTION 2. TRANSFER OF SHARES. Transfers of shares of beneficial interest of any
shares  of the  Trust  shall be made only on the books of the Trust by the owner
thereof or by his  attorney  thereunto  authorized  by a power of attorney  duly
executed  and filed with the  Secretary or a transfer  agent,  and only upon the
surrender of any  certificate or certificates  for such shares.  The Trust shall
not impose any  restrictions  upon the transfer of the shares of the Trust,  but
this  requirement  shall not prevent the  charging of customary  transfer  agent
fees.

SECTION 3. TRANSFER AGENT AND REGISTRAR;  REGULATIONS.  The Trust shall,  if and
whenever the Trustees shall so determine,  maintain one or more transfer offices
or agencies,  each in the charge of a transfer agent designated by the Trustees,
where  the  shares  of  beneficial  interest  of the  Trust  shall  be  directly
transferable.  The Trust shall, if and whenever the Trustees shall so determine,
maintain  one or more  registry  offices,  each  in the  charge  of a  registrar
designated  by the  Trustees,  where such  shares  shall be  registered,  and no
certificate  for shares of the Trust in respect of which a transfer agent and/or
registrar shall have been designated shall be valid unless countersigned by such
transfer agent and/or registered by such registrar. The principal transfer agent
may be located within or without the  Commonwealth  of  Massachusetts  and shall
have charge of the stock transfer books, lists and records,  which shall be kept
within or without  Massachusetts  in an office  which  shall be deemed to be the
stock transfer  office of the Trust.  The Trustees may also make such additional
rules and  regulations as it may deem expedient  concerning the issue,  transfer
and registration of certificates for shares of the Trust.

SECTION 4. CLOSING OF TRANSFER  BOOKS AND FIXING  RECORD DATE.  The Trustees may
fix in advance a time which shall be not more than seventy-five (75) days before
the date of any  meeting  of  shareholders,  or the date for the  payment of any
dividend or the making or any  distribution  to  shareholders or the last day on
which the consent or dissent of  shareholders  may be effectively  expressed for
any purpose,  as the record date for  determining  the  shareholders  having the
right to notice of and to vote at such meeting,  and any adjournment thereof, or
the right to receive  such  dividend or  distribution  or the right to give such
consent or dissent,  and in such case only shareholders of record on such record
date shall have such right,  notwithstanding any transfer of shares on the books
of the Trust after the record date. The Trustees may, without fixing such record
date, close the transfer books for all or any part of such period for any of the
foregoing purposes.

SECTION 5. LOST, DESTROYED OR MUTILATED  CERTIFICATES.  The holder of any shares
of the Trust  shall  immediately  notify the Trust of any loss,  destruction  or
mutilation  of  the  certificate  therefor,  and  the  Trustees  may,  in  their


                                      -6-
<PAGE>

discretion, cause a new certificate or certificates to be issued to him, in case
of  mutilation  of  the  certificate,   upon  the  surrender  of  the  mutilated
certificate,  or,  in  case  of loss or  destruction  of the  certificate,  upon
satisfactory proof of such loss or destruction and, in any case, if the Trustees
shall so determine, upon the delivery of a bond in such form and in such sum and
with such surety or sureties as the Trustees may direct,  to indemnify the Trust
against any claim that may be made  against it on account of the alleged loss or
destruction of any such certificate.

SECTION 6.  RECORD  OWNER OF SHARES.  The Trust  shall be  entitled to treat the
person in whose  name any share of the Trust is  registered  on the books of the
Trust as the owner thereof, and shall not be bound to recognize any equitable or
other  claim to or  interest  in such  share or  shares on the part of any other
person.


                                   ARTICLE VII

                                   Fiscal Year

      The fiscal year of the Trust shall end on June 30 of each year,  provided,
however, that the Trustees may from time to time change the fiscal year.


                                  ARTICLE VIII

                                      Seal

      The Trustees may adopt a seal of the Trust which shall be in such form and
shall  have  such  inscription  thereon  as the  Trustees  may from time to time
prescribe.

                                   ARTICLE IX

                               Inspection of Books

      The Trustees shall from time to time determine whether and to what extent,
and at what times and places,  and under what  conditions  and  regulations  the
accounts  and books of the Trust or any of them shall be open to the  inspection
of the  shareholders;  and no  shareholder  shall have any right to inspect  any
account  or  book  or  document  of the  Trust  except  as  conferred  by law or
authorized by the Trustees or by resolution of the shareholders.

                     Principal Custodian and Sub-custodians

      The following  provisions  shall apply to the  employment of the principal
Custodian pursuant to the Declaration of Trust:

      (a)   The Trust may employ the principal Custodian:

            (1)   To hold  securities  owned by the Trust and  deliver  the same
                  upon written order or oral order, if confirmed in writing,  or
                  by such electro-mechanical or electronic devices as are agreed
                  to by the Trust and such Custodian;

            (2)   To  receive  and  receipt  for any moneys due to the Trust and
                  deposit  the same in its own  banking  department  or,  as the
                  Trustees  may direct,  in any bank,  trust  company or banking
                  institution approved by such Custodian, provided that all such
                  deposits  shall be subject  only to the draft or order of such
                  Custodian; and

            (3)   To disburse such funds upon orders or vouchers.

      (b)   The Trust may also employ such Custodian as its agent:

            (1)   To keep the  books  and  accounts  of the  Trust  and  furnish
                  clerical and accounting services; and

            (2)   To  compute  the net  asset  value  per  share  in the  manner
                  approved by the Trust.

      (c)   All of the foregoing  services shall be performed upon such basis of
            compensation  as may be  agreed  upon  between  the  Trust  and  the
            principal  Custodian.  If so  directed  by vote of the  holders of a
            majority of the outstanding shares of Trust, the principal Custodian
            shall  deliver and pay over all  property of the Trust held by it as
            specified in such vote.

      (d)   In case of the  resignation,  removal or  inability to serve
            of any such Custodian,  the Trustees shall promptly  appoint
            another bank or trust company  meeting the  requirements  of
            the Declaration of Trust as successor  principal  Custodian.
            The  agreement  with the principal  Custodian  shall provide
            that the retiring  principal  Custodian shall,  upon receipt
            of  notice  of  such  appointment,  deliver  the  funds  and
            property of the Trust in its  possession to and only to such
            successor,  and  that  pending  appointment  of a  successor
            principal  Custodian,  or a  vote  of  the  shareholders  to
            function  without  a  principal  Custodian,   the  principal
            Custodian  shall not deliver funds and property of the Trust
            to the  Trustees,  but may  deliver  them to a bank or trust
            company doing business in Boston, Massachusetts,  of its own
            selection,   having  an  aggregate   capital,   surplus  and
            undivided  profits,  as shown by its last published  report,
            of not less than  $2,000,000,  as the  property of the Trust


                                      -8-
<PAGE>

            to be held under  terms  similar to those on which they were
            held by the retiring principal Custodian.

      The Trust may also authorize the principal Custodian to employ one or more
sub-custodians from time to time to perform such of the acts and services of the
Custodian  and upon such terms and  conditions as may be agreed upon between the
Custodian and sub-custodian.

      Subject to such rules, regulations and orders as the Commission may adopt,
the Trust may authorize or direct the principal  Custodian or any  sub-custodian
to deposit all or any part of the securities in or with one or more depositories
or clearing  agencies or systems for the central handling of securities or other
book-entry  systems  approved by the Trust,  or in or with such other persons or
systems as may be permitted by the  Commission,  or otherwise in accordance with
the Act,  pursuant to which all securities of any particular  class or series of
any  issuer  deposited  within the system  are  treated as  fungible  and may be
transferred or pledged by bookkeeping  entry without  physical  delivery of such
securities,  provided that all such deposits shall be subject to withdrawal only
upon the order of the Trust or the principal Custodian or the sub-custodian. The
Trust may also  authorize  the deposit in or with one or more  eligible  foreign
custodians (or in or with one or more foreign depositories, clearing agencies or
systems for the central  handling of  securities)  of all or part of the Trust's
foreign  assets,  securities,  cash and cash  equivalents in amounts  reasonably
necessary to effect the Trust's foreign investment  transactions,  in accordance
with such rules, regulations and orders as the Commission may adopt.


                                   ARTICLE XI

                  Limitation of Liability and Indemnification

SECTION 1. LIMITATION OF LIABILITY. Provided they have exercised reasonable care
and have acted under the  reasonable  belief that their  actions are in the best
interest of the Trust,  the Trustees shall not be  responsible  for or liable in
any event for neglect or wrongdoing of them or any officer,  agent,  employee or
investment  adviser of the Trust,  but nothing  contained in the  Declaration of
Trust or herein  shall  protect any Trustee  against any  liability  to which he
would  otherwise be subject by reason of wilful  misfeasance,  bad faith,  gross
negligence  or reckless  disregard of the duties  involved in the conduct of his
office.

SECTION 2.  INDEMNIFICATION OF TRUSTEES AND OFFICERS.  The Trust shall indemnify
each  person  who was or is a party or is  threatened  to be made a party to any
threatened,  pending or completed  action,  suit or  proceeding,  whether civil,
criminal,  administrative or investigative,  by reason of the fact that he is or
has been a Trustee,  officer,  employee or agent of the Trust, or is or has been
serving at the request of the Trust as a Trustee, director, officer, employee or
agent  of  another  corporation,  partnership,  joint  venture,  trust  or other
enterprise,  against expenses (including attorneys' fees), judgments,  fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action, suit or proceeding, provided that:

            (a)   such person acted in good faith and in a manner he  reasonably
                  believed to be in or not opposed to the best  interests of the
                  Trust,

            (b)   with respect to any criminal  action or proceeding,  he had no
                  reasonable cause to believe his conduct was unlawful,


                                      -9-
<PAGE>


            (c)   unless  ordered by a court,  indemnification  shall be
                  made only as  authorized  in the specific  case upon a
                  determination  that  indemnification  of the  Trustee,
                  officer,   employee   or  agent  is   proper   in  the
                  circumstances   because  he  has  met  the  applicable
                  standard  of conduct  set forth in  subparagraphs  (a)
                  and (b) above and (e) below, such  determination to be
                  made based upon a review of  readily  available  facts
                  (as opposed to a full trial-type  inquiry) by (i) vote
                  of a majority of the Disinterested  Trustees acting on
                  the  matter   (provided   that  a   majority   of  the
                  Disinterested  Trustees  then  in  office  act  on the
                  matter)  or (ii) by  independent  legal  counsel  in a
                  written opinion,

            (d)   in the case of an  action  or suit by or in the  right
                  of the Trust to  procure a judgment  in its favor,  no
                  indemnification  shall  be  made  in  respect  of  any
                  claim,  issue or matter as to which such person  shall
                  have been  adjudged  to be liable  for  negligence  or
                  misconduct  in  the  performance  of his  duty  to the
                  Trust  unless and only to the extent that the court in
                  which such  action or suit is  brought,  or a court of
                  equity  in the  county  in  which  the  Trust  has its
                  principal  office,  shall  determine upon  application
                  that,  despite the  adjudication  of liability  but in
                  view  of all  the  circumstances  of the  case,  he is
                  fairly and  reasonably  entitled to indemnify for such
                  expenses which such court shall deem proper, and

            (e)   no  indemnification or other protection shall be made or given
                  to any Trustee or officer of the Trust  against any  liability
                  to the  Trust  or to its  security  holders  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.

      Expenses  (including  attorneys' fees) incurred with respect to any claim,
action, suit or proceeding of the character described in the preceding paragraph
shall be paid by the Trust in  advance  of the final  disposition  thereof  upon
receipt of an  undertaking  by or on behalf of such  person to repay such amount
unless it shall  ultimately be determined  that he is entitled to be indemnified
by the Trust as authorized by this Article, provided that either:

            (1)   such  undertaking  is secured  by a surety  bond or some other
                  appropriate  security provided by the recipient,  or the Trust
                  shall  be  insured  against  losses  arising  out of any  such
                  advances; or

            (2)   a majority of the Disinterested  Trustees acting on the matter
                  (provided that a majority of the Disinterested Trustees act on
                  the  matter)  or an  independent  legal  counsel  in a written
                  opinion  shall  determine,  based  upon a  review  of  readily
                  available  facts (as  opposed to a full  trial-type  inquiry),
                  that there is reason to believe that the recipient  ultimately
                  will be found entitled to indemnification.


                                      -10-
<PAGE>


      As used in this Section 2, a "Disinterested Trustee" is one who is not (i)
an "Interested  Person," as defined in the Act, of the Trust  (including  anyone
who has been exempted from being an "Interested Person" by any rule, regulation,
or order of the  Securities  and Exchange  Commission),  or (ii) involved in the
claim, action, suit or proceeding.

      The  termination  of any action,  suit or proceeding  by judgment,  order,
settlement,  conviction,  or upon a plea of nolo  contendere or its  equivalent,
shall not, of itself,  create a presumption  that the person did not act in good
faith and in a manner  which he  reasonably  believed to be in or not opposed to
the best  interests  of the Trust,  or with  respect to any  criminal  action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

SECTION 3.  INDEMNIFICATION  OF SHAREHOLDERS.  In case any shareholder or former
shareholder  shall be held to be personally liable solely by reason of his being
or having been a  shareholder  and not because of his acts or  omissions  or for
some  other  reason,  the  shareholder  or  former  shareholder  (or his  heirs,
executors,  administrators or other legal  representatives,  or in the case of a
corporation or other entity,  its corporate or other general successor) shall be
entitled  out of the  Trust  estate  to be held  harmless  from and  indemnified
against all loss and expense arising from such liability.  The Trust shall, upon
request by the  shareholder,  assume the  defense of any claim made  against any
shareholder  for any act or  obligation  of the Trust and satisfy  any  judgment
thereon.  A holder of shares of a series  shall be entitled  to  indemnification
hereunder only out of assets allocated to that series.


                                   ARTICLE XII

                             Report to Shareholders

      The Trustees  shall at least  semi-annually  submit to the  shareholders a
written  financial report of the  transactions of the Trust including  financial
statements  which shall at least  annually be  certified by  independent  public
accountants.

                                  ARTICLE XIII

                                   Amendments

      These By-Laws may be amended at any meeting of the Trustees by a vote of a
majority of the Trustees then in office;  provided,  however, that any provision
of Article XI may be amended only by a two-thirds vote.


                                      -11-

                                IMPORTANT NOTICE:

      When you sign your name to the Transfer Form without filling in the name
of your "Assignee" this stock certificate becomes fully negotiable, similar to a
check endorsed in blank. Therefore, to safeguard a signed certificate, it is
recommended that you fill in the name of the new owner in the "Assignee" space.

      Alternatively, instead of using this Transfer Form, you may sign a
separate "stock power" form and then mail the unsigned stock certificate and the
signed "stock power" in separate envelopes. For added protection, use registered
mail for a stock certificate.

                           Dividend Reinvestment Plan

<PAGE>








      Dear Shareholder:

            We are pleased  that you have chosen to invest in Eaton Vance Senior
      Income  Trust (the  "Fund")  and are happy to provide  you with a Dividend
      Reinvestment  Plan (the  "Plan") for the  automatic  reinvestment  of your
      dividends  and capital gains  distributions.  The features of the Plan are
      described in this  brochure.  To  participate  automatically  in the Plan,
      either your common  shares of beneficial  interest of the Fund  ("Shares")
      must be  registered in your name, or if your Shares are held in nominee or
      "street" name through your  broker-dealer,  your  broker-dealer  must be a
      participant in the Plan.

            You may  terminate  your  participation  in the Plan at any time and
      thereby elect to receive  future  dividends in cash instead of Shares.  If
      you have  previously  terminated your  participation  in the Plan, you may
      rejoin it at any time by notifying First Data Investor Services Group. You
      also may withdraw a portion of your Shares  credited to your account under
      the Plan and remain a participant with respect to future distributions.

            We invite you to review the Plan.  If your Shares are  registered in
      your own name,  you are  automatically  enrolled as a  participant  in the
      Plan. If you do not wish to be a participant in the Plan,  simply complete
      and mail the withdrawal card in the enclosed  business reply  envelope.  A
      broker-dealer is automatically enrolled as a participant in the Plan until
      it withdraws  from the Plan.  If your Shares are  registered in nominee or
      "street"  name  through your  broker-dealer  and your  broker-dealer  is a
      participant  in the  Plan,  your  Shares  will be  included  in the  Plan;
      however,  your broker-dealer may offer a service under which you may elect
      to  have  your  dividends  and   distributions   paid  in  cash.  If  your
      broker-dealer  has terminated  participation in the Plan, you will receive
      any future dividends or distributions in cash; however, your broker-dealer

TERMS AND CONDITIONS OF EATON VANCE SENIOR INCOME TRUST DIVIDEND  REINVESTMENT
PLAN

      All  shareholders  who own  common  shares  of  beneficial  interest  (the
"Shares")  participating (the "Participants") in the Dividend  Reinvestment Plan
(the "Plan") of the Eaton Vance  Senior  Income Trust (the "Fund") will be bound
by the following provisions:

      First Data  Investor  Services  Group (the  "Agent") will act as Agent for
each  Participant,  and will open an account for each Participant under the Plan
in the same name as their present Shares are registered, and put into effect for
them the  dividend  reinvestment  option of the Plan as of the first record date
for a dividend or capital gains distribution.

      The Fund will declare its income dividends and capital gains distributions
payable  in  Shares,  or,  at the  option  of the  shareholders,  in cash.  Each
Participant that does not choose cash distributions shall take such distribution
entirely in Shares.  If on the payment date for a dividend or distribution,  the
net  asset  value is equal to or less  than the  market  price  per  Share  plus
estimated  brokerage  commissions,  the Agent shall  automatically  receive such
Shares,  including  fractions,  for each  Participant's  account  except  in the
circumstances  described  below.  Except in such  circumstances,  the  number of
additional  shares  to be  credited  to  each  Participant's  account  shall  be
determined by dividing the dollar amount of the income dividend or capital gains
distribution  payable by the greater of the net asset value per Share determined
as of the date of purchase or 95% of the then current  market price per Share on
the payment date.

      Should the net asset  value per share of Shares  exceed  the market  price
plus  estimated  brokerage  commissions  on the payment date for a Share or cash
income  dividend or capital  gains  distribution,  the Agent or a  broker-dealer
selected by the Agent shall endeavor,  for a purchase period of 30 days to apply
the amount of such dividend or distribution on each  Participant's  Shares (less
their pro rata  share of  brokerage  commissions  incurred  with  respect to the
Agent's  open-market  purchases  in  connection  with the  reinvestment  of such
dividend  or  distribution)  to  purchase  Shares  on the open  market  for each
Participant's  account. In no event may such purchases be made more than 30 days
after the payment date for such dividend except where  temporary  curtailment or
suspension  of purchase is necessary  to comply with  applicable  provisions  of
federal  securities  laws.  If, at the close of  business  on any day during the
purchase  period the net asset value per Share equals or is less than the market
price plus estimated brokerage commissions,  the Agent will not make any further
open-market  purchases in connection  with the  reinvestment of such dividend or
distribution. If the Agent is unable to invest the full dividend or distribution
amount through open-market purchases during the purchase period, the Agent shall
request  that,  with  respect  to the  uninvested  portion of such  dividend  or
distribution  amount,  the Fund issue new Shares at the close of business on the

                                       3
<PAGE>




earlier  of the last day of the  purchase  period or the first  day  during  the
purchase  period on which the net asset  value per Share  equals or is less than
the market price, plus estimated brokerage commissions, such Shares to be issued
in accordance with the term specified herein.  These newly issued Shares will be
valued at the then-current market price they are to be issued.

For purposes of making the dividend  reinvestment  purchase comparison under the
Plan,  (a) the  market  price of Shares on a  particular  date shall be the last
sales price on the New York Stock Exchange (the "Exchange") on that date, or, if
there is no sale on such  Exchange  on that  date,  then the  mean  between  the
closing bid and asked  quotations  on such Exchange on such date and (b) the net
asset  value per Share on a  particular  date  shall be the net asset  value per
Share most recently calculated by or on behalf of the Fund.

      Open-market  purchases  provided  for above may be made on any  securities
exchange  where  Shares  are  traded,  in  the  over-the-counter  market  or  in
negotiated  transactions  and may be on such  terms as to  price,  delivery  and
otherwise as the Agent shall determine. Each Participant's uninvested funds held
by the Agent will not bear  interest,  and it is understood  that, in any event,
the Agent shall have no liability in  connection  with any inability to purchase
Shares  within  30 days  after  the  initial  date of such  purchase  as  herein
provided, or with the timing of any purchases effected.  The Agent shall have no
responsibility  as to the  value  of  Shares  acquired  for  each  Participant's
account.  For the  purpose of cash  investments,  the Agent may  commingle  each
Participant's  funds with those of other  shareholders  of the Fund for whom the
Agent  similarly  acts as Agent,  and the  average  price  (including  brokerage
commissions)  of all Shares  purchased  by the Agent as Agent shall be the price
per Share allocable to each Participant in connection therewith.

      The Agent may hold each Participant's Shares acquired pursuant to the Plan
together with the Shares of other  shareholders of the Fund acquired pursuant to
the Plan in  noncertificated  form in the  Agent's  name or that of the  Agent's
nominee.  The Agent will  forward  to each  Participant  any proxy  solicitation
material;  and will  vote any  shares  so held  for  each  Participant  first in
accordance  with  the   instructions  set  forth  on  proxies  returned  by  the
Participant  to the Fund,  and then with  respect to any proxies not returned by
the  Participant  to the Fund in the same  portion  as the agent  votes  proxies
returned by the Participants to the Fund. Upon a Participant's  written request,
the Agent will deliver to the  Participant,  without  charge,  a certificate  or
certificates for the full shares.

      Each  Participant  will  be  sent a  confirmation  by the  Agent  of  each
acquisition  made for their account as soon as practicable but not later than 60
days after the date  thereof.  Although each  Participant  may from time to time
have an undivided  fractional  interest  (computed to four decimal  places) in a
share of the Fund,  no  certificates  for a  fractional  share  will be  issued.
However,  dividends and  distributions on fractional  shares will be credited to
each  Participant's  account.  In the event of  termination  of a  Participant's
account under the Plan, the Agent will adjust for any such undivided  fractional
interest in cash at the market value of Shares at the time of termination.

                                       4
<PAGE>




      Any share dividends or split shares distributed by the Fund on Shares held
by the Agent for Participants  will be credited to their accounts.  In the event
that the Fund makes available to its shareholders  rights to purchase additional
shares of other securities,  the Shares held for each Participant under the Plan
will be added to other shares held by the  Participant in calculating the number
of rights to be issued to each Participant.

      The Agent's service fee for handling capital gains distributions or income
dividends will be paid by the Fund. Each  Participant  will be charged their pro
rata share of brokerage commissions on all open-market purchases.

      Each  Participant  may terminate their account under the Plan by notifying
the Agent in writing.  Such  termination  will be effective  immediately  if the
Participant's  notice is  received  by the Agent not less than ten days prior to
any dividend or distribution  record date,  otherwise such  termination  will be
effective  shortly  after the  investment of such  dividend  distributions  with
respect to any subsequent  dividend or distribution.  The Plan may be terminated
by the Agent or the Fund upon notice in writing  mailed to each  Participant  at
least 90 days  prior to any  record  date for the  payment  of any  dividend  or
distribution  by the  Fund.  Upon  any  termination,  the  Agent  will  cause  a
certificate  or  certificates  to be issued  for the full  shares  held for each
Participant  under the Plan and cash adjustment for any fraction to be delivered
to them  without  charge.  If a  Participant  elects  by  notice to the Agent in
writing  in advance  of such  termination  to have the Agent sell part or all of
their Shares and remit the proceeds to them, the Agent is authorized to deduct a
$5.00 fee plus brokerage commission for this transaction from the proceeds.

      These terms and conditions may be amended or  supplemented by the Agent or
the Fund at any time or times but,  except  when  necessary  or  appropriate  to
comply  with  applicable  law or the rules or  policies  of the  Securities  and
Exchange Commission or any other regulatory  authority,  only by mailing to each
Participant  appropriate  written notice at least 30 days prior to the effective
date thereof. The amendment or supplement shall be deemed to be accepted by each
Participant  unless,  prior to the effective  date thereof,  the Agent  receives
written  notice of the  termination  of their account  under the Plan.  Any such
amendment  may include an  appointment  by the Agent of a successor  Agent under
these terms and conditions,  with full power and authority to perform all or any
of the acts to be performed by the Agent under these terms and conditions.  Upon
any such  appointment  of any Agent for the purpose of receiving  dividends  and
distributions,  the Fund will be authorized to pay to such successor  Agent, for
each Participant's  account, all dividends an distributions payable on Shares of
the Fund held in their name or under the Plan for  retention or  application  by
such successor Agent as provided in these terms and conditions.

      The Agent  shall at all times act in good  faith and agree to use its best
efforts  within  reasonable  limits  to  insure  the  accuracy  of all  services
performed under this Agreement and to comply with applicable law, but assumes no
responsibility  and shall not be liable for loss or damage due to errors  unless
such error is caused by the Agent's negligence, bad faith, or willful misconduct
or that of its employees.

      These  terms  and  conditions  shall  be  governed  by  the  laws  of  the

                         EATON VANCE SENIOR INCOME TRUST

                          INVESTMENT ADVISORY AGREEMENT


      AGREEMENT  made this day of October,  1998,  between  Eaton  Vance  Senior
Income Trust, a  Massachusetts  business  trust (the  "Trust"),  and Eaton Vance
Management, a Massachusetts business trust (the "Adviser").

      1. DUTIES OF THE ADVISER.  The Trust hereby  employs the Adviser to act as
investment  adviser for and to manage the  investment  and  reinvestment  of the
assets of the Trust and to administer its affairs, subject to the supervision of
the  Trustees  of the  Trust,  for the period and on the terms set forth in this
Agreement.

      The Adviser  hereby accepts such  employment,  and undertakes to afford to
the Trust the advice and assistance of the Adviser's  organization in the choice
of  investments  and in the  purchase  and sale of interests in Senior Loans (as
defined in the Trust's registration  statement) and other permitted  investments
for the  Trust and to  furnish  for the use of the  Trust  office  space and all
necessary  office   facilities,   equipment  and  personnel  for  servicing  the
investments  of the Trust and to pay the  salaries  and fees of all officers and
Trustees  of the Trust who are  members of the  Adviser's  organization  and all
personnel of the Adviser performing services relating to research and investment
activities.  The  Adviser  shall  for all  purposes  herein  be  deemed to be an
independent  contractor  and shall,  except as otherwise  expressly  provided or
authorized,  have no authority  to act for or represent  the Trust in any way or
otherwise be deemed an agent of the Trust.

      The Adviser shall provide the Trust with such  investment  management  and
supervision as the Trust may from time to time consider necessary for the proper
supervision of the Trust. As investment  adviser to the Trust, the Adviser shall
furnish continuously an investment program and shall determine from time to time
what interests in Senior Loans and other securities shall be acquired,  disposed
of or exchanged and what portion of the Trust's assets shall be held uninvested,
subject  always to the  applicable  restrictions  of the  Declaration  of Trust,
By-Laws and registration  statement of the Trust. The Adviser is authorized,  in
its discretion and without prior consultation with the Trust, to buy, sell, lend
and  otherwise  trade in any Senior  Loans,  stocks,  bonds,  debt  instruments,
options and other securities and investment  instruments on behalf of the Trust,
to purchase, write or sell derivative instruments on behalf of the Trust, and to
execute  any and all  agreements  and  instruments  and to do any and all things
incidental  thereto in connection  with the investment  management of the Trust.
Should  the  Trustees  of the  Trust at any  time,  however,  make any  specific
determination  as to  investment  policy for the Trust and  notify  the  Adviser
thereof in writing,  the Adviser  shall be bound by such  determination  for the
period, if any,  specified in such notice or until similarly  notified that such
determination has been revoked.  The Adviser shall take, on behalf of the Trust,
all actions which it deems  necessary or desirable to implement  the  investment
policies of the Trust.

      The Adviser  shall place all orders for the  purchase or sale of portfolio
securities for the account of the Trust either  directly with the issuer or with
brokers  or  dealers  or banks  selected  by the  Adviser,  or  directly  with a
co-lender  or other  participant  in Senior  Loans (as  defined  in the  Trust's
registration statement),  and to that end the Adviser is authorized as the agent
of the Trust to give instructions to the custodian of the Trust as to deliveries

<PAGE>




of securities  and payments of cash for the account of the Trust.  In connection
with the  selection  of such brokers or dealers or banks and the placing of such
orders,  the  Adviser  shall use its best  efforts to seek to execute  portfolio
security  transactions at prices which are advantageous to the Trust and (when a
disclosed  commission  is being  charged) at reasonably  competitive  commission
rates.  In  selecting  brokers or  dealers  qualified  to  execute a  particular
transaction,  brokers or dealers may be selected who also provide  brokerage and
research services (as those terms are defined in Section 28(e) of the Securities
Exchange Act of 1934) to the Adviser and the Adviser is expressly  authorized to
cause the Trust to pay any  broker or dealer who  provides  such  brokerage  and
research services a commission for executing a security  transaction which is in
excess of the amount of commission  another  broker or dealer would have charged
for effecting that transaction if the Adviser determines in good faith that such
amount of commission is reasonable in relation to the value of the brokerage and
research services  provided by such broker or dealer,  viewed in terms of either
that particular  transaction or the overall  responsibilities  which the Adviser
and its  affiliates  have with  respect to  accounts  over  which they  exercise
investment  discretion.  Subject  to the  requirement  set  forth in the  second
sentence of this paragraph,  the Adviser is authorized to consider,  as a factor
in the  selection of any broker or dealer with whom  purchase or sale orders may
be placed,  the fact that such broker or dealer has sold or is selling shares of
any one or more investment companies sponsored by the Adviser or its affiliates.

      The  Adviser  shall  not be  responsible  for  providing  certain  special
administrative  services  to  the  Trust  under  this  Agreement.   Eaton  Vance
Management,  in its capacity as Administrator of the Trust, shall be responsible
for  providing   such   services  to  the  Trust  under  the  Trust's   separate
Administration Agreement.

      2. COMPENSATION OF THE ADVISER. For the services,  payments and facilities
to be  furnished  hereunder  by the  Adviser,  the Adviser  shall be entitled to
receive  from  the  Trust  compensation  in an  amount  equal  to  17/240  of 1%
(equivalent  to .85%  annually)  of  average  daily  gross  assets  of the Trust
throughout  each month.  (Gross  assets shall be  calculated  by  deducting  all
liabilities  of the Trust except the principal  amount of any  indebtedness  for
money borrowed, including debt securities issued by the Trust.)

      Such  daily  compensation  shall be paid  monthly  in  arrears on the last
business  day of each month.  The Trust's  daily net assets shall be computed in
accordance with the  Declaration of Trust of the Trust and any applicable  votes
and determinations of the Trustees of the Trust.

      In case of initiation or  termination  of the Agreement  during any month,
the fee for that  month  shall be  reduced  proportionately  on the basis of the
number of calendar  days  during  which the  Agreement  is in effect and the fee
shall be computed  upon the basis of the average  gross  assets for the business
days the Agreement is so in effect for that month.

      The  Adviser  may,  from  time to time,  waive  all or a part of the above
compensation.

      3.  ALLOCATION  OF CHARGES AND EXPENSES.  It is understood  that the Trust
will pay all  expenses  other than those  expressly  stated to be payable by the
Adviser  hereunder,  which expenses payable by the Trust shall include,  without
implied  limitation,  (i) expenses of  maintaining  the Trust and continuing its
existence,  (ii)  registration of the Trust under the Investment  Company Act of
1940, (iii)  commissions,  spreads,  fees and other expenses  connected with the

                                       2
<PAGE>




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 listing shares of the Trust with a stock
exchange,  and expenses of issue,  sale,  repurchase  and redemption (if any) of
interests in the Trust,  including  expenses of conducting tender offers for the
purpose of  repurchasing  Trust  interests,  (viii)  expenses of registering and
qualifying the Trust and its shares under federal and state  securities laws and
of preparing and filing registration statements and amendments for such purposes
(ix)  expenses  of  reports  and  notices to  shareholders  and of  meetings  of
shareholders  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 Trust (including  without
limitation  safekeeping of funds,  securities and other investments,  keeping of
books, accounts and records, and determination of net asset values), (xiv) fees,
expenses and  disbursements  of transfer  agents,  dividend  disbursing  agents,
shareholder  servicing agents and registrars for all services to the Trust, (xv)
expenses  for  servicing  shareholder  accounts,  (xvi) any  direct  charges  to
shareholders  approved by the  Trustees of the Trust,  (xvii)  compensation  and
expenses  of  Trustees  of the  Trust  who  are  not  members  of the  Adviser's
organization,  (xviii) pricing and valuation services employed by the Trust, and
(xix) such  non-recurring  items as may arise,  including  expenses  incurred in
connection  with  litigation,  proceedings  and claims and the obligation of the
Trust to indemnify its Trustees, officers and shareholders with respect thereto.

      4. OTHER  INTERESTS.  It is  understood  that Trustees and officers of the
Trust and  shareholders  of the Trust are or may be or become  interested in the
Adviser as trustees,  officers,  employees,  shareholders  or otherwise and that
trustees,  officers  and  shareholders  of the  Adviser  are or may be or become
similarly  interested  in the  Trust,  and that  the  Adviser  may be or  become
interested  in the Trust as  Holder or  otherwise.  It is also  understood  that
trustees,  officers,  employees and shareholders of the Adviser may be or become
interested  (as  directors,  trustees,  officers,  employees,   shareholders  or
otherwise) in other companies or entities (including,  without limitation, other
investment  companies)  which the Adviser may organize,  sponsor or acquire,  or
with which it may merge or  consolidate,  and which may include the words "Eaton
Vance" or any combination thereof as part of their name, and that the Adviser or
its subsidiaries or affiliates may enter into advisory or management  agreements
or other contracts or relationships with such other companies or entities.

      5. LIMITATION OF LIABILITY OF THE ADVISER.  The services of the Adviser to
the Trust are not to be deemed to be exclusive, the Adviser being free to render
services to others and engage in other  business  activities.  In the absence of
willful  misfeasance,  bad faith,  gross  negligence  or reckless  disregard  of
obligations  or duties  hereunder on the part of the Adviser,  the Adviser shall
not be subject to liability to the Trust or to any shareholder the Trust for any
act or  omission  in the  course  of,  or  connected  with,  rendering  services
hereunder or for any losses which may be sustained in the  acquisition,  holding
or disposition of any interest in a Loan or of any security, investment or other
asset.

      6.   SUB-INVESTMENT   ADVISERS.   The  Adviser  may  employ  one  or  more
sub-investment  advisers  from  time to time to  perform  such of the  acts  and
services  of the  Adviser,  including  the  selection  of  brokers or dealers to
execute the Trust's  portfolio  security  transactions,  and upon such terms and
conditions  as may be agreed upon  between  the Adviser and such  sub-investment
adviser and  approved  by the  Trustees of the Trust,  all as  permitted  by the
Investment Company Act of 1940.

                                       3

      7. DURATION AND TERMINATION OF THIS AGREEMENT. This Agreement shall become
effective  upon the date of its  execution,  and,  unless  terminated  as herein
provided,  shall remain in full force and effect through and including  February
28, 2000 and shall  continue in full force and effect  indefinitely  thereafter,
but only so long as such  continuance  after  February 28, 2000 is  specifically
approved at least  annually (i) by the Board of Trustees of the Trust or by vote
of a majority of the outstanding  voting securities of the Trust and (ii) by the
vote of a majority of those Trustees of the Trust who are not interested persons
of the  Adviser or the Trust cast in person at a meeting  called for the purpose
of voting on such approval.

      Either  party  hereto may,  at any time on sixty (60) days' prior  written
notice to the  other,  terminate  this  Agreement  without  the  payment  of any
penalty,  by action of Trustees of the Trust or the trustees of the Adviser,  as
the case may be, and the Trust may, at any time upon such written  notice to the
Adviser,  terminate  this  Agreement  by vote of a majority  of the  outstanding
voting securities of the Trust. This Agreement shall terminate  automatically in
the event of its assignment.

      8. AMENDMENTS OF THE AGREEMENT. This Agreement may be amended by a writing
signed by both parties  hereto,  provided  that no  amendment to this  Agreement
shall  be  effective  until  approved  (i) by the  vote of a  majority  of those
Trustees of the Trust who are not interested persons of the Adviser or the Trust
cast in person at a meeting  called for the purpose of voting on such  approval,
and (ii) by vote of a  majority  of the  outstanding  voting  securities  of the
Trust.

      9.  LIMITATION  OF  LIABILITY.  The  Adviser  expressly  acknowledges  the
provision  in the  Declaration  of  Trust of the  Trust  limiting  the  personal
liability of the  Trustees,  officers  and  shareholders  of the Trust,  and the
Adviser  hereby  agrees that it shall have  recourse to the Trust for payment of
claims or obligations  as between the Trust and the Adviser  arising out of this
Agreement  and  shall  not  seek  satisfaction  from  any  Trustee,  officer  or
shareholders of the Trust.

      10. USE OF THE NAME "EATON VANCE".  The Adviser hereby consents to the use
by the Trust of the name "Eaton  Vance" as part of the Trust's  name;  provided,
however,  that such consent  shall be  conditioned  upon the  employment  of the
Adviser or one of its  affiliates as the  investment  adviser of the Trust.  The
name  "Eaton  Vance" or any  variation  thereof may be used from time to time in
other  connections  and for other purposes by the Adviser and its affiliates and
other  investment  companies  that have obtained  consent to the use of the name
"Eaton  Vance".  The Adviser  shall have the right to require the Trust to cease
using the name "Eaton  Vance" as part of the Trust's  name if the Trust  ceases,
for any reason,  to employ the Adviser or one of its  affiliates  as the Trust's
investment  adviser.  Future names  adopted by the Trust for itself,  insofar as
such names include identifying words requiring the consent of the Adviser, shall
be the  property  of the  Adviser  and shall be  subject  to the same  terms and
conditions.

      11. CERTAIN  DEFINITIONS.  The terms "assignment" and "interested persons"
when used herein shall have the respective  meanings specified in the Investment
Company Act of 1940 as now in effect or as hereafter  amended subject,  however,
to such  exemptions as may be granted by the Securities and Exchange  Commission
by  any  rule,  regulation  or  order.  The  term  "vote  of a  majority  of the
outstanding   voting   securities"   shall  mean  the  vote,  at  a  meeting  of
shareholders,  of the  lesser of (a) 67 per  centum or more of the shares of the
Trust present or represented by proxy at the meeting if the Holders of more than
50 per centum of the shares of the Trust are present or  represented by proxy at
the meeting, or (b) more than 50 per centum of the shares of the Trust.

facilities to be furnished hereunder by the Administrator, the Fund shall pay to

days the Agreement is so in effect for that month.

compensation.
