EATON VANCE GROWTH TRUST (THE "TRUST").

     Shares of the Fund are not deposits or  obligations  of, or  guaranteed  or

An investor would pay the following contingent deferred sales charge and expenses on a
$1,000 investment, assuming (a) 5% annual return and (b) redemption at the end of each
time period:                                                                                  $73         $110
An investor would pay the following expenses on the same investment, assuming (a) 5%
annual return and (b) no redemptions:                                                         $23         $ 70

Notes: 
<FN>
<F1>The  purpose of the above  table and  Example is to  summarize  the  aggregate  expenses  of the Fund and the
    Portfolio and to assist investors in understanding  the various costs and expenses that investors in the Fund
    will bear  directly or  indirectly.  The Trustees of the Trust believe that over time the aggregate per share
    expenses of the Fund and the Portfolio should be  approximately  equal to or less than the per share expenses
    which the Fund would incur if the Trust retained the services of an investment  adviser and the assets of the
    Fund were invested directly in the type of securities being held by the Portfolio.  Because the Fund does not
    yet have a sufficient  operating history,  the percentages  indicated as Annual Fund and Allocated  Portfolio
    Operating  Expenses  in the table and the  amounts  included  in the  Example are based on the Fund's and the
    Portfolio's  projected  fees and expenses  for the current  fiscal year ending  August 31, 1995.  The Example
    should not be considered a  representation  of past or future  expenses and actual expenses may be greater or
    less than those shown. The Example assumes a 5% annual return and the Fund's actual performance may result in
    an annual return greater or less than 5%. For further information regarding the expenses of both the Fund and
    the  Portfolio  see  "The  Fund's  Financial  Highlights",  "Organization  of the  Fund  and the  Portfolio",
    "Management of the Fund and the  Portfolio" and "How to Redeem Fund Shares".  Because the Fund makes payments
    under its Distribution Plan adopted under Rule 12b-1, a long-term  shareholder may pay more than the economic
    equivalent  of the  maximum  front-end  sales  charge  permitted  by a rule of the  National  Association  of
    Securities Dealers, Inc. See "Distribution Plan".
<F2>No  contingent  deferred  sales  charge is imposed on (a) shares  purchased  more than six years prior to the
    redemption, (b) shares acquired through the reinvestment of distributions or (c) any appreciation in value of
    other shares in the account (see "How to Redeem Fund Shares"),  and no such charge is imposed on exchanges of
    Fund shares for shares of one or more other funds listed under "The Eaton Vance Exchange Privilege".
<F3>The Fund expects to begin accruing for its service fee payments during the quarter ending December 31, 1995.
<F4>Other investment companies with different  distribution  arrangements and fees are investing in the Portfolio
    and additional such companies may do so in the future. See "Organization of the Fund and the Portfolio".

THE FUND'S INVESTMENT OBJECTIVE
- --------------------------------------------------------------------------------
   
EV MARATHON GROWTH FUND'S INVESTMENT OBJECTIVE IS TO ACHIEVE CAPITAL GROWTH. The
Fund currently seeks to meet its investment objective by investing its assets in
the Growth Portfolio,  a separate registered  investment company.  The Portfolio
has the  same  investment  objective  as the  Fund and  invests  in a  carefully
selected  and  continuously  managed  portfolio  consisting  primarily of equity
securities.   The  Fund's  and  the   Portfolio's   investment   objectives  are
nonfundamental  and may be changed when  authorized by a vote of the Trustees of
the Trust or the Portfolio,  respectively, without obtaining the approval of the
Fund's  shareholders or the investors in the Portfolio,  as the case may be. The
Trustees of the Trust have no present  intention to change the Fund's  objective
and intend to submit any proposed material change in the investment objective to
shareholders  in  advance  for their  approval.

HOW THE FUND AND THE  PORTFOLIO INVEST THEIR ASSETS; INVESTMENT RISKS
- --------------------------------------------------------------------------------
THE  FUND  SEEKS  TO  ACHIEVE  ITS  INVESTMENT  OBJECTIVE  BY  INVESTING  IN THE
PORTFOLIO.  The policy of the Portfolio is to invest in a carefully selected and
continuously  managed  portfolio  consisting  primarily  of domestic and foreign
securities.  It may invest in all kinds of companies.  The Portfolio will invest
primarily  in  common  stocks  or  securities  convertible  into  common  stocks
(including  convertible  debt),  which the Investment  Adviser believes meet the
criteria for capital  appreciation.  The criteria for investments in convertible
debt are the same as used for the common stock of an issuer.  The Portfolio does
not  currently  intend to invest  more than 5% of its net assets in  convertible
debt. It may also invest in other securities and obligations of all kinds. These
include preferred stocks,  rights,  warrants,  bonds,  repurchase agreements and
other  evidences of  indebtedness;  however,  the  Portfolio  does not currently
intend to invest more than 5% of its net assets in each of such  investments and
currently  intends  to  limit  its  investments  in   non-convertible   debt  to
non-convertible  debt  rated  investment  grade  (i.e.,  rated  Baa or higher by
Moody's  Investors  Service,  Inc. or BBB or higher by Standard & Poor's Ratings
Group) or, if unrated, determined to be of comparable quality by the Portfolio's
Investment Adviser. The Portfolio may also invest in money market instruments.
    

    While income is a subordinate consideration to capital growth, the Portfolio
will earn dividend or interest  income to the extent that it receives  dividends
or interest from its investments.

   
    The  Portfolio  may  invest  in  securities   issued  by  foreign  companies
(including American Depository  Receipts and Global Depository  Receipts).  Such
investments may be subject to various risks such as fluctuations in currency and
exchange rates, foreign taxes, social,  political and economic conditions in the
countries in which such companies operate, and changes in governmental, economic
or monetary policies both here and abroad.  There may be less publicly available
information  about a foreign company than about a comparable  domestic  company.
Since the securities  markets in many foreign  countries are not as developed as
those in the United States,  the  securities of many foreign  companies are less
liquid and their prices are more volatile than securities of comparable domestic
companies.  In order to hedge against  possible  variations in foreign  exchange
rates pending the settlement of foreign securities  transactions,  the Portfolio
may buy or sell foreign  currencies or may enter into forward  foreign  currency
exchange contracts to purchase or sell a specified currency at a specified price
and future date.

    The Portfolio  may purchase and sell  exchange-traded  futures  contracts on
stock indices and options  thereon to hedge against  fluctuations  in securities
prices  or as a  substitute  for  the  purchase  or  sale  of  securities.  Such
transactions involve a risk of loss or depreciation due to unanticipated adverse
changes  in  securities  prices,   which  may  exceed  the  Portfolio's  initial
investment in these contracts.  Futures contracts involve transactions costs. To
the extent that the Portfolio enters into futures  contracts and options thereon
traded on an exchange regulated by the Commodity Futures Trading Commission,  in
each case that are not for bona fide hedging  purposes (as defined by the CFTC),
the aggregate  initial margin and premiums required to establish these positions
(excluding the amount by which options are  "in-the-money") may not exceed 5% of
the liquidation  value of the Portfolio's  portfolio,  after taking into account
unrealized  profits and  unrealized  losses on any  contracts  the Portfolio has
entered into.  There can be no assurance  that the  Investment  Adviser's use of
stock index futures will be advantageous to the Portfolio.

     An investment in the Fund entails the risk that the principal value of Fund
shares may not increase or may decline.  The  Portfolio's  investments in equity
securities are subject to the risk of adverse developments  affecting particular
companies or industries and the stock market generally.

     The Fund and the  Portfolio  have adopted  certain  fundamental  investment
restrictions  which are  enumerated  in detail in the  Statement  of  Additional
Information and which may not be changed unless authorized by a shareholder vote
and an investor vote, respectively.  Except for such enumerated restrictions and
as otherwise indicated in this Prospectus, the investment objective and policies
of the Fund and the Portfolio are not  fundamental  policies and accordingly may
be changed by the Trustees of the Trust and the Portfolio  without obtaining the
approval of the Fund's  shareholders  or the investors in the Portfolio,  as the
case may be. If any change  were made in the Fund's  investment  objective,  the
Fund might have an investment  objective  different from the objective  which an
investor considered appropriate at the time the investor became a shareholder of
the Fund.
    
- --------------------------------------------------------------------------------
  THE  FUND  IS  NOT  INTENDED  TO  BE  A  COMPLETE  INVESTMENT  PROGRAM,  AND
  PROSPECTIVE  INVESTORS  SHOULD TAKE INTO ACCOUNT THEIR  OBJECTIVES AND OTHER
  INVESTMENTS  WHEN  CONSIDERING THE PURCHASE OF FUND SHARES.  THE FUND CANNOT
  ASSURE ACHIEVEMENT OF ITS CAPITAL GROWTH OBJECTIVE.
- --------------------------------------------------------------------------------

ORGANIZATION OF THE FUND AND THE PORTFOLIO
- --------------------------------------------------------------------------------
THE FUND IS A DIVERSIFIED  SERIES OF EATON VANCE GROWTH TRUST,  A BUSINESS TRUST
ESTABLISHED UNDER MASSACHUSETTS LAW PURSUANT TO A DECLARATION OF TRUST DATED MAY
25,  1989,  AS  AMENDED,  AND  ORGANIZED  AS THE  SUCCESSOR  TO A  MASSACHUSETTS
CORPORATION WHICH COMMENCED ITS INVESTMENT COMPANY OPERATIONS IN 1954. THE TRUST
IS A MUTUAL FUND -- AN OPEN-END,  MANAGEMENT INVESTMENT COMPANY. The Trustees of
the Trust are  responsible  for the overall  management  and  supervision of its
affairs.  The  Trust  may issue an  unlimited  number  of  shares of  beneficial
interest  (no par value per share) in one or more  series and  because the Trust
can offer separate series (such as the Fund) it is known as a "series  company."
Each share represents an equal  proportionate  beneficial  interest in the Fund.
When issued and outstanding,  the shares are fully paid and nonassessable by the
Trust  and   redeemable  as  described   under  "How  to  Redeem  Fund  Shares."
Shareholders  are  entitled  to one vote for each full  share  held.  Fractional
shares may be voted  proportionately.  Shares have no  preemptive  or conversion
rights and are freely transferable. In the event of the liquidation of the Fund,
shareholders  are  entitled  to  share  pro rata in the net  assets  of the Fund
available for distribution to shareholders.

   
    THE  PORTFOLIO  IS  ORGANIZED  AS A TRUST UNDER THE LAWS OF THE STATE OF NEW
YORK AND INTENDS TO BE TREATED AS A PARTNERSHIP  FOR FEDERAL TAX  PURPOSES.  The
Portfolio,  as well as the Trust,  intends to comply with all applicable Federal
and state  securities  laws. The Portfolio's  Declaration of Trust provides that
the Fund and other entities  permitted to invest in the Portfolio  (e.g.,  other
U.S. and foreign  investment  companies,  and common and commingled trust funds)
will each be liable for all obligations of the Portfolio.  However,  the risk of
the Fund  incurring  financial  loss on account of such  liability is limited to
circumstances in which both inadequate insurance exists and the Portfolio itself
is  unable  to meet its  obligations.  Accordingly,  the  Trustees  of the Trust
believe that neither the Fund nor its shareholders will be adversely affected by
reason  of the Fund  investing  in the  Portfolio.

SPECIAL INFORMATION ON THE FUND/PORTFOLIO  INVESTMENT STRUCTURE.  An investor in
the Fund  should be aware that the Fund,  unlike  mutual  funds  which  directly
acquire and manage  their own  portfolios  of  securities,  seeks to achieve its
investment  objective  by investing  its assets in an interest in the  Portfolio
(although the Fund may temporarily hold a de minimus amount of cash), which is a
separate investment company with an identical investment  objective.  Therefore,
the Fund's  interest in the  securities  owned by the Portfolio is indirect.  In
addition to selling an interest to the Fund, the Portfolio may sell interests to
other affiliated and  non-affiliated  mutual funds or  institutional  investors.
Such investors will invest in the Portfolio on the same terms and conditions and
will pay a proportionate share of the Portfolio's  expenses.  However, the other
investors  investing in the  Portfolio  are not required to sell their shares at
the  same  public  offering  price  as the  Fund  due  to  variations  in  sales
commissions  and other  operating  expenses.  Therefore,  investors  in the Fund
should be aware that these  differences  may  result in  differences  in returns
experienced by investors in the various funds that invest in the Portfolio. Such
differences  in  returns  are also  present  in other  mutual  fund  structures,
including funds that have multiple classes of shares. For information  regarding
the investment objective, policies and restrictions,  see "The Fund's Investment
Objective" and "How the Fund and the Portfolio  Invest their Assets;  Investment
Risks".  Further information  regarding investment practices may be found in the
Statement of Additional Information.
    

    The Trustees of the Trust have  considered the advantages and  disadvantages
of investing the assets of the Fund in the Portfolio,  as well as the advantages
and  disadvantages  of the  two-tier  format.  The  Trustees  believe  that  the
structure  offers  opportunities  for  substantial  growth in the  assets of the
Portfolio,  and affords the  potential  for  economies of scale for the Fund, at
least when the assets of the Portfolio exceed $300 million.

    The Fund may withdraw  (completely redeem) all its assets from the Portfolio
at any time if the Board of Trustees of the Trust  determines  that it is in the
best  interest  of  the  Fund  to  do  so.  The  investment  objective  and  the
nonfundamental  investment policies of the Fund and the Portfolio may be changed
by the Trustees of the Trust and the Portfolio without obtaining the approval of
the shareholders of the Fund or the investors in the Portfolio.  Any such change
of the  investment  objective  will be preceded by thirty days' advance  written
notice to the shareholders of the Fund or the investors in the Portfolio, as the
case  may be.  If a  shareholder  redeems  shares  because  of a  change  in the
nonfundamental objective or policies of the Fund, those shares may be subject to
a contingent deferred sales charge, as described in "How to Redeem Fund Shares".
In the event the Fund  withdraws  all of its assets from the  Portfolio,  or the
Board of Trustees of the Trust  determines that the investment  objective of the
Portfolio is no longer  consistent  with the  investment  objective of the Fund,
such Trustees would consider what action might be taken, including investing the
assets  of the  Fund  in  another  pooled  investment  entity  or  retaining  an
investment adviser to manage the Fund's assets in accordance with its investment
objective.  The Fund's investment performance may be affected by a withdrawal of
all its assets from the Portfolio.

    Information regarding other pooled investment entities or funds which invest
in the Portfolio may be obtained by contacting  Eaton Vance  Distributors,  Inc.
(the "Principal  Underwriter" or "EVD"),  24 Federal Street,  Boston,  MA 02110,
(617) 482-8260.  Smaller investors in the Portfolio may be adversely affected by
the  actions of larger  investors  in the  Portfolio.  For  example,  if a large
investor  withdraws from the Portfolio,  the remaining  investors may experience
higher  pro  rata  operating   expenses,   thereby   producing   lower  returns.
Additionally,  the  Portfolio  may become less  diverse,  resulting in increased
portfolio  risk, and experience  decreasing  economies of scale.  However,  this
possibility exists as well for historically structured funds which have large or
institutional investors.

    Until  recently,  the  Administrator   sponsored  and  advised  historically
structured funds. Funds which invest all their assets in interests in a separate
investment  company are a relatively new development in the mutual fund industry
and,  therefore,  the  Fund  may  be  subject  to  additional  regulations  than
historically structured funds.

    The  Declaration of Trust of the Portfolio  provides that the Portfolio will
terminate  120 days  after  the  complete  withdrawal  of the Fund or any  other
investor in the Portfolio,  unless either the remaining investors,  by unanimous
vote at a meeting  of such  investors,  or a  majority  of the  Trustees  of the
Portfolio,  by  written  instrument  consented  to by all  investors,  agree  to
continue the  business of the  Portfolio.  This  provision  is  consistent  with
treatment of the Portfolio as a partnership for Federal income tax purposes. See
"Distributions  and  Taxes" for  further  information.  Whenever  the Fund as an
investor in the  Portfolio  is requested  to vote on matters  pertaining  to the
Portfolio (other than the termination of the Portfolio's business,  which may be
determined by the Trustees of the Portfolio without investor approval), the Fund
will hold a meeting  of Fund  shareholders  and will  vote its  interest  in the
Portfolio for or against such matters  proportionately  to the  instructions  to
vote for or against such matters received from Fund shareholders. The Fund shall
vote shares for which it receives no voting  instructions in the same proportion
as the shares for which it receives voting instructions.  Other investors in the
Portfolio may alone or collectively  acquire  sufficient voting interests in the
Portfolio to control matters  relating to the operation of the Portfolio,  which
may require the Fund to withdraw its  investment  in the Portfolio or take other
appropriate action. Any such withdrawal could result in a distribution "in kind"
of portfolio  securities (as opposed to a cash distribution from the Portfolio).
If securities  are  distributed,  the Fund could incur  brokerage,  tax or other
charges in converting the securities to cash. In addition,  the  distribution in
kind may result in a less  diversified  portfolio  of  investments  or adversely
affect the  liquidity of the Fund.  Notwithstanding  the above,  there are other
means for meeting shareholder redemption requests, such as borrowing.

     The  Trustees  of the  Trust,  including  a majority  of the  noninterested
Trustees,  have approved written procedures designed to identify and address any
potential  conflicts of interest  arising from the fact that the Trustees of the
Trust and the Trustees of the Portfolio are the same.  Such  procedures  require
each Board to take action to resolve any  conflict of interest  between the Fund
and the Portfolio,  and it is possible that the creation of separate  Boards may
be considered.  For further information  concerning the Trustees and officers of
the Trust and the Portfolio, see the Statement of Additional Information.

MANAGEMENT OF THE FUND AND THE PORTFOLIO
- --------------------------------------------------------------------------------
THE PORTFOLIO  ENGAGES BOSTON  MANAGEMENT AND RESEARCH  ("BMR"),  A WHOLLY-OWNED
SUBSIDIARY OF EATON VANCE MANAGEMENT ("EATON VANCE"), AS ITS INVESTMENT ADVISER.
EATON VANCE,  ITS  AFFILIATES AND ITS  PREDECESSOR  COMPANIES HAVE BEEN MANAGING
ASSETS OF  INDIVIDUALS  AND  INSTITUTIONS  SINCE  1924 AND  MANAGING  INVESTMENT
COMPANIES SINCE 1931.

   
    Acting  under  the  general  supervision  of the  Board of  Trustees  of the
Portfolio,  BMR manages  the  Portfolio's  investments  and  affairs.  Under its
investment  advisory  agreement  with the  Portfolio,  BMR  receives  a  monthly
advisory fee of 5/96 of 1% (equivalent to 0.625%  annually) of the average daily
net assets of the  Portfolio up to and including  $300  million,  and 1/24 of 1%
(equivalent  to 0.50%  annually)  of the  average  daily  net  assets  over $300
million. For the period from the start of business,  August 2, 1994, to February
28, 1995, the Portfolio paid BMR advisory fees equivalent to 0.625% (annualized)
of the Portfolio's average daily net assets for such period.

    BMR furnishes  for the use of the  Portfolio  office space and all necessary
office facilities,  equipment and personnel for servicing the investments of the
Portfolio. BMR also places the portfolio transactions of the Portfolio with many
broker-dealer  firms  and uses its best  efforts  to  obtain  execution  of such
transactions at prices which are advantageous to the Portfolio and at reasonably
competitive  commission rates. Subject to the foregoing,  BMR may consider sales
of shares of the Fund or of other investment companies sponsored by BMR or Eaton
Vance as a factor in the selection of broker-dealer  firms to execute  portfolio
transactions.

    Peter F. Kiely has acted as the portfolio  manager of the Portfolio since it
commenced operations. He has been a Vice President of Eaton Vance since 1980 and
of BMR since 1992.
    

    BMR OR EATON VANCE ACTS AS INVESTMENT  ADVISER TO  INVESTMENT  COMPANIES AND
VARIOUS  INDIVIDUAL AND  INSTITUTIONAL  CLIENTS WITH ASSETS UNDER  MANAGEMENT OF
APPROXIMATELY  $15 BILLION.  Eaton Vance is a  wholly-owned  subsidiary of Eaton
Vance Corp., a publicly-held  holding  company.  Eaton Vance Corp.,  through its
subsidiaries  and  affiliates,  engages in investment  management  and marketing
activities,  fiduciary and banking services, oil and gas operations, real estate
investment,  consulting  and  management,  and  development  of precious  metals
properties.

    The Trust has retained  the services of Eaton Vance to act as  Administrator
of the Fund.  The Trust has not retained the services of an  investment  adviser
since  the  Trust  seeks to  achieve  the  investment  objective  of the Fund by
investing  the Fund's assets in the  Portfolio.  As  Administrator,  Eaton Vance
provides the Fund with general  office  facilities  and  supervises  the overall
administration of the Fund. For these services Eaton Vance currently receives no
compensation.  The  Trustees  of the  Trust may  determine,  in the  future,  to
compensate  Eaton Vance for such  services.

     The Portfolio  and the Fund,  as the case may be, will each be  responsible
for all of its respective  costs and expenses not expressly stated to be payable
by BMR  under  the  investment  advisory  agreement,  by Eaton  Vance  under the
administrative  services agreement,  or by EVD under the distribution agreement.
Such costs and expenses to be borne by the  Portfolio  and the Fund, as the case
may be,  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 and the
governmental  fees;  expenses of reporting to shareholders and investors;  proxy
statements and other expenses of shareholders' or investors' meetings; insurance
premiums;  printing and mailing  expenses;  interest,  taxes and corporate fees;
legal and  accounting  expenses;  compensation  and  expenses  of  Trustees  not
affiliated with BMR or Eaton Vance;  and investment  advisory fees, and, if any,
administrative  services  fees.  The  Portfolio or the Fund, as the case may be,
will also each bear expenses incurred in connection with litigation in which the
Portfolio or the Fund,  as the case may be, is a party and any legal  obligation
to indemnify its respective officers and Trustees with respect thereto.

DISTRIBUTION PLAN
- ------------------------------------------------------------------------------
THE FUND FINANCES  DISTRIBUTION  ACTIVITIES AND HAS ADOPTED A DISTRIBUTION  PLAN
(THE "PLAN")  PURSUANT TO RULE 12B-1  UNDER THE INVESTMENT  COMPANY ACT OF 1940.
Rule 12b-1  permits a mutual fund,  such  as the Fund,  to finance  distribution
activities  and bear expenses  associated  with the  distribution  of its shares
provided  that any payments made by the Fund are made pursuant to a written plan
adopted in accordance  with the Rule. The Plan is subject to, and complies with,
the sales charge rule of the National  Association of Securities  Dealers,  Inc.
(the "NASD Rule").  The Plan is described further in the Statement of Additional
Information,  and the following is a description of the salient  features of the
Plan. The Plan provides that the Fund,  subject to the NASD Rule, will pay sales
commissions and distribution fees to the Principal Underwriter only after and as
a  result  of the  sale of  shares  of the  Fund.  On each  sale of Fund  shares
(excluding  reinvestment  of  distributions)  the Fund  will  pay the  Principal
Underwriter amounts representing (i) sales commissions equal to 5% of the amount
received by the Fund for each share sold and (ii)  distribution  fees calculated
by applying the rate of 1% over the prime rate then  reported in The Wall Street
Journal  to the  outstanding  balance  of  Uncovered  Distribution  Charges  (as
described  below)  of  the  Principal  Underwriter.  The  Principal  Underwriter
currently expects to pay sales commissions (except on exchange  transactions and
reinvestments) to a financial  services firm (an "Authorized  Firm") at the time
of sale equal to 4% of the purchase  price of the shares sold by such Firm.  The
Principal  Underwriter will use its own funds (which may be borrowed from banks)
to pay such  commissions.  Because  the  payment  of the sales  commissions  and
distribution  fees to the  Principal  Underwriter  is  subject  to the NASD Rule
described  below,  it will take the  Principal  Underwriter a number of years to
recoup the sales  commissions  paid by it to Authorized  Firms from the payments
received by it from the Fund pursuant to the Plan.

   
    THE NASD  RULE  REQUIRES  THE FUND TO LIMIT  ITS  ANNUAL  PAYMENTS  OF SALES
COMMISSIONS AND DISTRIBUTION FEES TO THE PRINCIPAL  UNDERWRITER TO AN AMOUNT NOT
EXCEEDING  .75% OF THE FUND'S  AVERAGE  DAILY NET ASSETS FOR EACH  FISCAL  YEAR.
Under its Plan the Fund accrues  daily an amount at the rate of 1/365 of .75% of
the Fund's net assets,  and pays such accrued  amounts  monthly to the Principal
Underwriter.  The Plan requires such accruals to be  automatically  discontinued
during  any  period in which  there are no  outstanding  Uncovered  Distribution
Charges under the Plan. Uncovered Distribution Charges are calculated daily and,
briefly, are equivalent to all unpaid sales commissions and distribution fees to
which the Principal  Underwriter  is entitled under the Plan less all contingent
deferred sales charges theretofore paid to the Principal Underwriter.  The Eaton
Vance organization may be considered to have realized a profit under the Plan if
at any point in time the  aggregate  amounts  of all  payments  received  by the
Principal  Underwriter  from  the  Fund  pursuant  to the  Plan,  including  any
contingent deferred sales charges,  have exceeded the total expenses theretofore
incurred by such organization in distributing shares of the Fund. Total expenses
for this purpose will include an allocable portion of the overhead costs of such
organization and its branch offices.

    Because of the NASD Rule  limitation on the amount of sales  commissions and
distribution  fees paid to the Principal  Underwriter  during any fiscal year, a
high  level of sales of Fund  shares  during  the  initial  years of the  Fund's
operations would cause a large portion of the sales commission attributable to a
sale of  Fund  shares  to be  accrued  and  paid  by the  Fund to the  Principal
Underwriter  in fiscal  years  subsequent  to the year in which such shares were
sold.  This  spreading  of sales  commissions  payments  under  the Plan over an
extended  period  would  result  in the  incurrence  and  payment  of  increased
distribution  fees under the Plan.  For the period  from the start of  business,
September 13, 1994, to February 28, 1995, the Fund paid sales  commissions under
the Plan equivalent to .75%  (annualized) of the Fund's average daily net assets
for such period. As at February 28, 1995, the Uncovered  Distribution Charges of
the Principal  Underwriter  calculated  under the Plan amounted to approximately
$27,052 (equivalent to 3.7% of the Fund's net assets on such day).

    THE PLAN ALSO  AUTHORIZES  THE FUND TO MAKE  PAYMENTS OF SERVICE FEES TO THE
PRINCIPAL  UNDERWRITER,  AUTHORIZED  FIRMS  AND OTHER  PERSONS  IN  AMOUNTS  NOT
EXCEEDING  .25% OF THE FUND'S AVERAGE DAILY NET ASSETS FOR EACH FISCAL YEAR. The
Trustees of the Trust have initially  implemented  the Plan by  authorizing  the
Fund to make quarterly payments of service fees to the Principal Underwriter and
Authorized  Firms in amounts not  expected to exceed .25% of the Fund's  average
daily net assets for any fiscal  year based on the value of Fund  shares sold by
such persons and remaining  outstanding for at least twelve months. As permitted
by the NASD  Rule,  such  payments  are made for  personal  services  and/or the
maintenance of shareholder accounts. Service fees are separate and distinct from
the sales commissions and distribution fees payable by the Fund to the Principal
Underwriter,  and as such are not subject to automatic discontinuance when there
are no outstanding Uncovered  Distribution Charges of the Principal Underwriter.
The Fund  expects to begin  accruing  for its  service fee  payments  during the
quarter ending December 31, 1995.

     The  Principal  Underwriter  may,  from time to time,  at its own  expense,
provide  additional  incentives  to  Authorized  Firms which  employ  registered
representatives  who sell a minimum  dollar  amount of the Fund's  shares and/or
shares  of  other  funds  distributed  by the  Principal  Underwriter.  In  some
instances,  such additional incentives may be offered only to certain Authorized
Firms whose  representatives are expected to sell significant amounts of shares.
In  addition,  the  Principal  Underwriter  may from  time to time  increase  or
decrease the sales commissions payable to Authorized Firms.
    

     The Fund may, in its absolute discretion, suspend, discontinue or limit the
offering  of its shares at any time.  In  determining  whether  any such  action
should be taken, the Fund's management intends to consider all relevant factors,
including  without  limitation the size of the Fund, the investment  climate and
market  conditions,  the volume of sales and redemptions of Fund shares, and the
amount of Uncovered Distribution Charges of the Principal Underwriter.  The Plan
may  continue in effect and payments  may be made under the Plan  following  any
such  suspension,  discontinuance  or limitation of the offering of Fund shares;
however,  the Fund is not  contractually  obligated to continue the Plan for any
particular period of time.  Suspension of the offering of Fund shares would not,
of course, affect a shareholder's ability to redeem shares.

VALUING FUND SHARES
- --------------------------------------------------------------------------------
THE FUND  VALUES ITS SHARES  ONCE ON EACH DAY 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 Fund's net asset value per
share is determined by its custodian,  Investors  Bank & Trust Company  ("IBT"),
(as agent for the Fund) in the manner  authorized  by the Trustees of the Trust.
Net asset value is computed by dividing  the value of the Fund's  total  assets,
less its  liabilities,  by the number of shares  outstanding.  Because  the Fund
invests its assets in an interest in the  Portfolio,  the Fund's net asset value
will  reflect  the  value of its  interest  in the  Portfolio  (which,  in turn,
reflects the underlying value of the Portfolio's assets and liabilities).

     Authorized  Firms must  communicate  an  investor's  order to the Principal
Underwriter  prior to the close of the Principal  Underwriter's  business day to
receive that day's net asset value per Fund share.  It is the Authorized  Firms'
responsibility to transmit orders promptly to the Principal  Underwriter,  which
is a wholly-owned subsidiary of Eaton Vance.
   
     The  Portfolio's  net  asset  value is also  determined  as of the close of
regular  trading  on the  Exchange  by IBT  (as  custodian  and  agent  for  the
Portfolio) in the manner authorized by the Trustees of the Portfolio.  Net asset
value is computed by subtracting the liabilities of the Portfolio from the value
of its total assets. Investments listed on securities exchanges or in the NASDAQ
National  Market are valued at closing  sale  prices.  For  further  information
regarding the valuation of the Portfolio's  assets,  see  "Determination  of Net
Asset Value" in the Statement of Additional Information.  Eaton Vance Corp. owns
77.3% of the outstanding stock of IBT, the Fund's and the Portfolio's custodian.
    

- ------------------------------------------------------------------------------
  SHAREHOLDERS  MAY DETERMINE THE VALUE OF THEIR INVESTMENT BY MULTIPLYING THE
  NUMBER OF FUND SHARES OWNED BY THE CURRENT NET ASSET VALUE PER SHARE.
- ------------------------------------------------------------------------------

HOW TO BUY FUND SHARES
- --------------------------------------------------------------------------------
SHARES OF THE FUND MAY BE PURCHASED  FOR CASH OR MAY BE ACQUIRED IN EXCHANGE FOR
SECURITIES.  Investors may purchase shares of the Fund through  Authorized Firms
at the net asset value per share of the Fund next  determined  after an order is
effective.  The Fund may  suspend  the  offering  of  shares at any time and may
refuse an order for the purchase of shares.

   
     An initial investment in the Fund must be at least $1,000.  Once an account
has been  established  the investor may send  investments  of $50 or more at any
time directly to the Fund's  Transfer Agent (the  "Transfer  Agent") as follows:
The Shareholder  Services Group, Inc., BOS725,  P.O. Box 1559, Boston, MA 02104.
The $1,000 minimum  initial  investment is waived for Bank  Automated  Investing
accounts, which may be established with an investment of $50 or more. See "Eaton
Vance Shareholder Services".
    

    In connection with employee benefit or other continuous group purchase plans
under which the average initial  purchase by a participant of the plan is $1,000
or more, the Fund may accept initial investments of less than $1,000 on the part
of an individual participant. In the event a shareholder who is a participant of
such a plan  terminates  participation  in the plan,  his or her shares  will be
transferred  to a regular  individual  account.  However,  such  account will be
subject to the right of redemption by the Fund as described under "How to Redeem
Fund Shares."

ACQUIRING  FUND SHARES IN EXCHANGE FOR  SECURITIES.  IBT, as escrow agent,  will
receive securities acceptable to Eaton Vance, as Administrator,  in exchange for
Fund shares at their net asset value as determined  above.  The minimum value of
securities (or  securities and cash) accepted for deposit is $5,000.  Securities
accepted  will be sold by IBT as agent for the account of their owner on the day
of their receipt by IBT or as soon  thereafter  as possible.  The number of Fund
shares to be issued in exchange for  securities  will be the aggregate  proceeds
from the sale of such securities,  divided by the applicable net asset value per
Fund  share  on the day  such  proceeds  are  received.  Eaton  Vance  will  use
reasonable  efforts to obtain the then current market price for such  securities
but does not guarantee  the best  available  price.  Eaton Vance will absorb any
transaction costs, such as commissions, on the sale of the securities.

    Securities  determined to be acceptable should be transferred via book entry
or  physically  delivered,  in proper form for  transfer,  through an Authorized
Firm,  together with a completed and signed  Letter of  Transmittal  in approved
form (available from Authorized Firms), as follows:

    IN THE CASE OF BOOK ENTRY:

        Deliver through Depository Trust Co.
        Broker #2212
        Investors Bank & Trust Company
        For A/C EV Marathon Growth Fund

    IN THE CASE OF PHYSICAL DELIVERY:

        Investors Bank & Trust Company
        Attention: EV Marathon Growth Fund
        Physical Securities Processing Settlement Area
        89 South Street
        Boston, MA 02111

    Investors who are  contemplating an exchange of securities for shares of the
Fund, or their representatives,  are advised to contact Eaton Vance to determine
whether the securities are acceptable  before forwarding such securities to IBT.
Eaton Vance reserves the right to reject any securities.  Exchanging  securities
for Fund shares may create a taxable gain or loss.  Each investor should consult
his or her tax adviser with respect to the particular  Federal,  state and local
tax consequences of exchanging securities for Fund shares.

  IF YOU DON'T HAVE AN AUTHORIZED FIRM, EATON VANCE CAN RECOMMEND ONE.
- --------------------------------------------------------------------------------

HOW TO REDEEM FUND SHARES
- --------------------------------------------------------------------------------
A SHAREHOLDER MAY REDEEM FUND SHARES BY DELIVERING TO THE  SHAREHOLDER  SERVICES
GROUP, INC., BOS725,  P.O. BOX 1559, BOSTON, MA 02104, during its business hours
a written request for redemption in good order, plus any share certificates with
executed stock powers. The redemption price will be based on the net asset value
per Fund share next  computed  after such  delivery.  Good order  means that all
relevant  documents  must be  endorsed  by the record  owner (s)  exactly as the
shares are  registered  and the  signature(s)  must be guaranteed by a member of
either the Securities Transfer Association's STAMP program or the New York Stock
Exchange's  Medallion  Signature  Program,  or certain  banks,  savings and loan
institutions,  credit unions, securities dealers, securities exchanges, clearing
agencies and registered  securities  associations as required by a regulation of
the Securities and Exchange  Commission (the "Commission") and acceptable to The
Shareholder  Services  Group,  Inc. In addition,  in some cases,  good order may
require  the  furnishing  of  additional  documents  such as  where  shares  are
registered in the name of a corporation, partnership or fiduciary.

    Within seven days after receipt of a redemption request in good order by The
Shareholder Services Group, Inc., the Fund will make payment in cash for the net
asset value of the shares as of the date determined above, reduced by the amount
of any applicable  contingent  deferred sales charges  (described below) and any
Federal income tax required to be withheld.  Although the Fund normally  expects
to make payment in cash for redeemed  shares,  the Trust,  subject to compliance
with applicable regulations,  has reserved the right to pay the redemption price
of shares of the Fund, either totally or partially, by a distribution in kind of
readily  marketable  securities  withdrawn by the Fund from the  Portfolio.  The
securities so distributed would be valued pursuant to the Portfolio's  valuation
procedures.  If a shareholder  received a distribution  in kind, the shareholder
could incur brokerage or other charges in converting the securities to cash.

    To sell  shares at their net  asset  value  through  an  Authorized  Firm (a
repurchase),  a  shareholder  can place a repurchase  order with the  Authorized
Firm,  which may  charge a fee.  The value of such  shares is based upon the net
asset value calculated after EVD, as the Fund's agent, receives the order. It is
the Authorized Firm's  responsibility to transmit promptly  repurchase orders to
EVD.  Throughout this  Prospectus,  the word  "redemption" is generally meant to
include a  repurchase.

     If  shares  were  recently  purchased,   the  proceeds  of  redemption  (or
repurchase) will not be sent until the check (including a certified or cashier's
check)  received  for the  shares  purchased  has  cleared.  Payment  for shares
tendered for redemption may be delayed up to 15 days from the purchase date when
the purchase check has not yet cleared. Redemptions or repurchases may result in
a taxable gain or loss.

    Due to the high cost of maintaining  small  accounts,  the Fund reserves the
right to redeem  accounts  with  balances of less than  $1,000.  Prior to such a
redemption,  shareholders  will be  given  60 days'  written  notice  to make an
additional  purchase.  Thus, an investor making an initial  investment of $1,000
would  not be able to  redeem  shares  without  being  subject  to this  policy.
However,  no such  redemption  would be required by the Fund if the cause of the
low account  balance was a reduction in the net asset value of Fund  shares.  No
contingent   deferred  sales  charge  will  be  imposed  with  respect  to  such
involuntary  redemptions.

    CONTINGENT DEFERRED SALES CHARGE. Shares redeemed within the first six years
of  their  purchase   (except  shares  acquired   through  the  reinvestment  of
distributions)  generally will be subject to a contingent deferred sales charge.
This contingent deferred sales charge is imposed on any redemption the amount of
which exceeds the aggregate value at the time of redemption of (a) all shares in
the  account  purchased  more than six years  prior to the  redemption,  (b) all
shares in the account acquired through  reinvestment of  distributions,  and (c)
the increase,  if any, of value of all other shares in the account (namely those
purchased within the six years preceding the redemption) over the purchase price
of such shares.  Redemptions are processed in a manner to maximize the amount of
redemption  proceeds  which will not be subject to a contingent  deferred  sales
charge.  That is, each  redemption  will be assumed to have been made first from
the exempt  amounts  referred to in clauses (a),  (b) and (c) above,  and second
through  liquidation of those shares in the account referred to in clause (c) on
a  first-in-first-out  basis.  Any  contingent  deferred  sales  charge which is
required to be imposed on share  redemptions will be made in accordance with the
following schedule:

            YEAR OF                                            CONTINGENT
          REDEMPTION                                         DEFERRED SALES
        AFTER PURCHASE                                           CHARGE
        --------------                                       --------------
      First .............................................          5%
      Second ............................................          5%
      Third .............................................          4%
      Fourth ............................................          3%
      Fifth .............................................          2%
      Sixth .............................................          1%
      Seventh and following .............................          0%

    In calculating  the contingent  deferred sales charge upon the redemption of
Fund shares acquired in an exchange for shares of a fund currently  listed under
"The Eaton Vance  Exchange  Privilege",  the  contingent  deferred  sales charge
schedule  applicable  to the shares at the time of  purchase  will apply and the
purchase of Fund shares  acquired in the exchange is deemed to have  occurred at
the time of the  original  purchase  of the  exchanged  shares.  The  contingent
deferred  sales  charge  will be waived for shares  redeemed  (1)  pursuant to a
Withdrawal  Plan (see  "Eaton  Vance  Shareholder  Services"),  (2) as part of a
required distribution from a tax-sheltered retirement plan, or (3) following the
death of all  beneficial  owners of such  shares,  provided  the  redemption  is
requested  within one year of death (a death  certificate  and other  applicable
documents may be required).

   
    No  contingent  deferred  sales  charge will be imposed on Fund shares which
have  been  sold to  Eaton  Vance  or its  affiliates,  or to  their  respective
employees or clients.  The contingent  deferred sales charge will be paid to the
Principal Underwriter or the Fund.

- --------------------------------------------------------------------------------
  THE FOLLOWING EXAMPLE  ILLUSTRATES THE OPERATION OF THE CONTINGENT  DEFERRED
  SALES CHARGE. ASSUME THAT AN INVESTOR PURCHASES $10,000 OF THE FUND'S SHARES
  AND  THAT 16  MONTHS  LATER  THE  VALUE OF THE  ACCOUNT  HAS  GROWN  THROUGH
  INVESTMENT  PERFORMANCE AND REINVESTMENT OF  DISTRIBUTIONS  TO $12,000.  THE
  INVESTOR  THEN MAY  REDEEM  UP TO  $2,000  OF  SHARES  WITHOUT  INCURRING  A
  CONTINGENT  DEFERRED SALES CHARGE.  IF THE INVESTOR  SHOULD REDEEM $3,000 OF
  SHARES,  A CHARGE  WOULD BE  IMPOSED ON $1,000 OF THE  REDEMPTION.  THE RATE
  WOULD BE 5% BECAUSE  THE  REDEMPTION  WAS MADE IN THE SECOND  YEAR AFTER THE
  PURCHASE WAS MADE AND THE CHARGE WOULD BE $50.
- --------------------------------------------------------------------------------
    

REPORTS TO SHAREHOLDERS
- --------------------------------------------------------------------------------
THE  FUND  WILL  ISSUE  TO  ITS  SHAREHOLDERS  SEMI-ANNUAL  AND  ANNUAL  REPORTS
CONTAINING FINANCIAL STATEMENTS. Financial statements included in annual reports
are audited by the Fund's independent accountants. Shortly after the end of each
calendar year, the Fund will furnish all shareholders with information necessary
for preparing Federal and state tax returns.

THE LIFETIME INVESTING ACCOUNT/DISTRIBUTION OPTIONS
- --------------------------------------------------------------------------------
AFTER AN INVESTOR MAKES AN INITIAL PURCHASE OF FUND SHARES,  THE FUND'S TRANSFER
AGENT, THE SHAREHOLDER  SERVICES GROUP,  INC., WILL SET UP A LIFETIME  INVESTING
ACCOUNT  FOR THE  INVESTOR  ON THE FUND'S  RECORDS.  This  account is a complete
record of all transactions  between the investor and the Fund which at all times
shows the balance of shares  owned.  The Fund will not issue share  certificates
except upon request.

    Each  time  a  transaction  takes  place  in a  shareholder's  account,  the
shareholder will receive a statement showing complete details of the transaction
and the current balance in the account.  (Under certain plans, statements may be
sent only quarterly).  THE LIFETIME INVESTING ACCOUNT ALSO PERMITS A SHAREHOLDER
TO MAKE  ADDITIONAL  INVESTMENTS IN SHARES BY SENDING A CHECK FOR $50 OR MORE to
The Shareholder  Services Group,  Inc.

     Any questions concerning a shareholder's  account or services available may
be directed by telephone to EATON VANCE  SHAREHOLDER  SERVICES at  800-225-6265,
extension 2, or in writing to The Shareholder Services Group, Inc., BOS725, P.O.
Box 1559, Boston, MA 02104 (please provide the name of the shareholder, the Fund
and the account number).

THE FOLLOWING  DISTRIBUTION  OPTIONS WILL BE AVAILABLE TO ALL LIFETIME INVESTING
ACCOUNTS and may be changed as often as desired by written  notice to the Fund's
dividend  disbursing agent, The Shareholder  Services Group, Inc., BOS725,  P.O.
Box 1559,  Boston, MA 02104. The currently  effective option will appear on each

     Cash Option -- Dividends and capital gains will be paid in cash.

     The  Share  Option  will be  assigned  if no  other  option  is  specified.
Distributions,  including those  reinvested,  will be reduced by any withholding
required under Federal income tax laws.

     If the Income  Option or Cash  Option has been  selected,  dividend  and/or
capital gains distribution checks which are returned by the United States Postal
Service as not  deliverable or which remain uncashed for six months or more will
be  reinvested  in the account in shares at the then  current  net asset  value.
Furthermore,  the  distribution  option  on the  account  will be  automatically
changed  to the  Share  Option  until  such  time as the  shareholder  selects a
different option.

    DISTRIBUTION  INVESTMENT OPTION. In addition to the distribution options set
forth above, dividends and/or capital gains may be invested in additional shares
of another Eaton Vance fund. Before selecting this option, a shareholder  should
obtain a prospectus  of the other Eaton Vance fund and  consider its  objectives
and policies carefully.

    "STREET  NAME"  ACCOUNTS.  If shares of the Fund are held in a "street name"
account with an Authorized Firm, all recordkeeping,  transaction  processing and
payments of  distributions  relating to the beneficial  owner's  account will be
performed by the Authorized  Firm,  and not by the Fund and its Transfer  Agent.
Since the Fund will have no record of the  beneficial  owner's  transactions,  a
beneficial  owner should  contact the  Authorized  Firm to  purchase,  redeem or
exchange shares, to make changes in or give instructions concerning the account,
or to obtain information about the account.  The transfer of shares in a "street
name" account to an account with another  dealer or to an account  directly with
the Fund involves  special  procedures and will require the beneficial  owner to
obtain historical purchase  information about the shares in the account from the
Authorized Firm. Before  establishing a "street name" account with an investment
firm,  or  transferring  the  account to another  investment  firm,  an investor
wishing to reinvest  distributions  should determine whether the firm which will
hold the shares allows reinvestment of

THE EATON VANCE EXCHANGE PRIVILEGE
- --------------------------------------------------------------------------------
Shares of the Fund  currently  may be exchanged  for shares of one or more other
funds in the Eaton Vance  Marathon  Group of Funds (which  includes  Eaton Vance
Equity-Income  Trust and any EV  Marathon  fund,  except  Eaton Vance Prime Rate
Reserves) or Eaton Vance Money Market Fund,  which are distributed  subject to a
contingent  deferred sales charge, on the basis of the net asset value per share
of each fund at the time of the exchange,  provided that such offer is available
only in states where shares of the fund being acquired may be legally sold.

     Each exchange must involve  shares which have a net asset value of at least
$1,000. The exchange  privilege may be changed or discontinued  without penalty.
Shareholders  will be given sixty (60) days' notice prior to any  termination or
material  amendment  of the  exchange  privilege.  The Fund does not  permit the
exchange privilege to be used for "Market Timing" and may terminate the exchange
privilege for any  shareholder  account engaged in Market Timing  activity.  Any
shareholder account for which more than two round-trip exchanges are made within
any  twelve  month  period  will be  deemed  to be  engaged  in  Market  Timing.
Furthermore,  a group of  unrelated  accounts  for which  exchanges  are entered
contemporaneously  by a financial  intermediary will be considered to be engaged
in Market Timing.

     The Shareholder Services Group, Inc. makes exchanges at the next determined
net asset value after  receiving an exchange  request in good order (see "How to
Redeem  Fund  Shares").   Consult  The  Shareholder  Services  Group,  Inc.  for
additional  information  concerning  the exchange  privilege.  Applications  and
prospectuses of other funds are available from Authorized Firms or the Principal
Underwriter.  The prospectus  for each fund describes its investment  objectives
and policies,  and  shareholders  should obtain a prospectus  and consider these
objectives and policies carefully before requesting an exchange.

   
     No contingent  deferred sales charge is imposed on exchanges.  For purposes
of  calculating  the  contingent  deferred  sales charge upon the  redemption of
shares  acquired in an exchange,  the contingent  deferred sales charge schedule
applicable  to the shares at the time of purchase will apply and the purchase of
shares  acquired in one or more exchanges is deemed to have occurred at the time
of the original  purchase of the exchanged shares.  For the contingent  deferred
sales charge  schedule  applicable  to the Eaton Vance  Marathon  Group of Funds
(except EV Marathon  Strategic Income Fund and Class I shares of any EV Marathon
Limited Maturity Fund), see "How to Redeem Fund Shares." The contingent deferred
sales charge schedule  applicable to EV Marathon Strategic Income Fund and Class
I shares of any EV Marathon  Limited  Maturity Fund is 3%, 2.5%, 2% or 1% in the
event of a  redemption  occurring  in the first,  second,  third or fourth year,
respectively, after the original share purchase.
    

     Shares of the other  funds in the Eaton Vance  Marathon  Group of Funds and
shares of Eaton Vance Money Market Fund may be exchanged  for Fund shares on the
basis of the net asset value per share of each fund at the time of the exchange,
but  subject  to any  restrictions  or  qualifications  set  forth in a  current
prospectus of any such fund.

     Telephone  exchanges are accepted by The Shareholder  Services Group,  Inc.
provided the investor has not disclaimed in writing the use of the privilege. To
effect  such  exchanges,  call The  Shareholder  Services  Group,  Inc.  at 800-
262-1122 or, within  Massachusetts,  617-573-9403,  Monday through Friday,  9:00
a.m. to 4:00 p.m. (Eastern Standard Time). Shares acquired by telephone exchange
must be  registered  in the same name(s) and with the same address as the shares
being exchanged. Neither the Fund, the Principal Underwriter nor The Shareholder
Services  Group,  Inc.  will be  responsible  for the  authenticity  of exchange
instructions  received by  telephone,  provided  that  reasonable  procedures to
confirm that instructions communicated are genuine have been followed. Telephone
instructions  will be tape  recorded.  In times of  drastic  economic  or market
changes,  a telephone  exchange may be difficult to  implement.  An exchange may
result in a taxable gain or loss.

EATON VANCE SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
THE FUND OFFERS THE FOLLOWING  SERVICES,  WHICH ARE VOLUNTARY,  INVOLVE NO EXTRA
CHARGE,  AND MAY BE CHANGED OR  DISCONTINUED  WITHOUT  PENALTY AT ANY TIME. Full
information on each of the services  described below and an  application,  where
required, are available from Authorized Firms or the Principal Underwriter.  The
cost  of  administering  such  services  for the  benefit  of  shareholders  who
participate  in them is  borne by the Fund as an  expense  to all  shareholders.

   
INVEST-BY-MAIL  -- FOR  PERIODIC  SHARE  ACCUMULATION:  Once the $1,000  minimum
investment  has been  made,  checks  of $50 or more  payable  to the order of EV
Marathon Growth Fund may be mailed  directly to The Shareholder  Services Group,
Inc.,  BOS725,  P.O.  Box 1559,  Boston,  MA 02104 at any time -- whether or not
distributions  are  reinvested.  The name of the  shareholder,  the Fund and the
account number should accompany each investment.

WITHDRAWAL  PLAN: A shareholder may draw on  shareholdings  systematically  with
monthly or quarterly checks in an aggregate amount that does not exceed annually
12% of the account balance at the time the plan is established. Such amount will
not be subject to a contingent  deferred  sales charge.  See "How to Redeem Fund
Shares". A minimum deposit of $5,000 in shares is required.
    

BANK AUTOMATED INVESTING -- FOR REGULAR SHARE ACCUMULATION:  Cash investments of
$50 or more may be made automatically each month or quarter from a shareholder's
bank account. The $1,000 minimum initial investment and small account redemption
policy are waived for these accounts.

REINVESTMENT PRIVILEGE: A SHAREHOLDER WHO HAS REPURCHASED OR REDEEMED SHARES MAY
REINVEST,  WITH CREDIT FOR ANY  CONTINGENT  DEFERRED  SALES  CHARGES PAID ON THE
REDEEMED  OR  REPURCHASED  SHARES,  ANY  PORTION  OR ALL OF  THE  REPURCHASE  OR
REDEMPTION PROCEEDS (PLUS THAT AMOUNT NECESSARY TO ACQUIRE A FRACTIONAL SHARE TO
ROUND  OFF THE  PURCHASE  TO THE  NEAREST  FULL  SHARE)  IN  SHARES OF THE FUND,
provided that the  reinvestment is effected within 30 days after such repurchase
or  redemption.  Shares are sold to a reinvesting  shareholder  at the net asset
value next determined  following  timely receipt of a written  purchase order by
the Principal  Underwriter or by the Fund (or by the Fund's Transfer Agent).  To
the extent that any shares of the Fund are sold at a loss and the  proceeds  are
reinvested  in  shares of the Fund (or  other  shares  of the Fund are  acquired
within the period  beginning 30 days before and ending 30 days after the date of
the  redemption)  some or all of the loss generally will not be allowed as a tax
deduction.  Shareholders  should  consult their tax advisers  concerning the tax
consequences of reinvestments.

TAX-SHELTERED RETIREMENT PLANS: Shares of the Fund are available for purchase in
connection with the following tax-sheltered retirement plans:

    -- Pension  and  Profit   Sharing  Plans  for   self-employed   individuals,
       corporations and non-profit organizations;
      
    -- Individual  Retirement  Account  Plans for  individuals  and  their  non-
       employed spouses; and
      
    -- 403(b)   Retirement   Plans  for  employees  of  public  school  systems,
       hospitals,  colleges and other non-profit  organizations  meeting certain
       requirements  of the  Internal  Revenue  Code of 1986,  as  amended  (the
       "Code").

     Detailed information  concerning these plans,  including certain exceptions
to minimum investment  requirements,  and copies of the plans are available from
the  Principal  Underwriter.  This  information  should  be read  carefully  and
consultation  with an attorney or tax adviser may be advisable.  The information
sets forth the  service  fee  charged for  retirement  plans and  describes  the
Federal  income  tax  consequences  of  establishing  a plan.  Under all  plans,
dividends  and  distributions  will be  automatically  reinvested  in additional
shares.

DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
   
The Fund's present policy is to distribute  semi-annually  substantially  all of
the net  investment  income  allocated  to the Fund by the  Portfolio,  less the
Fund's direct and allocated  expenses,  and to distribute at least  annually any
net realized  capital  gains.  A portion of  distributions  from net  investment
income may be eligible for the  dividends-received  deduction for  corporations.
The Fund's  distributions from its net investment income, net short-term capital
gains, and certain net foreign exchange gains will be taxable to shareholders as
ordinary income,  whether received in cash or reinvested in additional shares of
the Fund. The Fund's  distributions from its long-term capital gains are taxable
to  shareholders as such,  whether  received in cash or reinvested in additional
shares of the Fund and  regardless  of the length of time shares have been owned
by  shareholders.  If shares are purchased  shortly  before the record date of a
distribution,  the  shareholder  will pay the full price for the shares and then
receive  some  portion  of the  price  back as a taxable  distribution.  Certain
distributions,  if  declared  in  October,  November  or  December  and paid the
following  January,  will be taxed to shareholders as if received on December 31
of the year in which they are declared.
    

    Shareholders will receive annually tax information notices and Forms 1099 to
assist in the  preparation  of their Federal and state tax returns for the prior
calendar year's distributions,  proceeds from the redemption or exchange of Fund
shares, and Federal income tax (if any) withheld by the Fund's Transfer Agent.

    In order to qualify as a regulated  investment  company under the Code,  the
Fund must satisfy  certain  requirements  relating to the sources of its income,
the  distribution  of its income,  and the  diversification  of its  assets.  In
satisfying  these  requirements,  the Fund  will  treat  itself  as  owning  its
proportionate  share of each of the  Portfolio's  assets and as  entitled to the
income of the Portfolio properly attributable to such share.

- ------------------------------------------------------------------------------
  AS A  REGULATED  INVESTMENT  COMPANY  UNDER  THE CODE THE FUND  DOES NOT PAY
  FEDERAL  INCOME  OR  EXCISE  TAXES  TO THE  EXTENT  THAT IT  DISTRIBUTES  TO
  SHAREHOLDERS  ITS NET  INVESTMENT  INCOME AND NET REALIZED  CAPITAL GAINS IN
  ACCORDANCE  WITH  THE  TIMING  REQUIREMENTS   IMPOSED  BY  THE  CODE.  AS  A
  PARTNERSHIP  UNDER THE CODE,  THE PORTFOLIO  DOES NOT PAY FEDERAL  INCOME OR
  EXCISE TAXES.
- ------------------------------------------------------------------------------

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
   
FROM TIME TO TIME, THE FUND MAY ADVERTISE ITS AVERAGE  ANNUAL TOTAL RETURN.  The
Fund's average annual total return is determined by computing the average annual
percentage  change in value of $1,000  invested at the maximum  public  offering
price (net asset  value)  for  specified  periods  ending  with the most  recent
calendar quarter, assuming reinvestment of all distributions. The average annual
total return calculation assumes a complete redemption of the investment and the
deduction of any applicable  contingent  deferred sales charge at the end of the
period.  The Fund may also publish  annual and  cumulative  total return figures
from time to time.
    

    The  Fund may also  publish  total  return  figures  which do not take  into
account  any  contingent  deferred  sales  charge  which  may  be  imposed  upon
redemptions at the end of the specified  period.  Any  performance  figure which
does not take into account the contingent deferred sales charge would be reduced
to the extent such charge is imposed upon a redemption.

   
    Investors should note that the investment results of the Fund will fluctuate
over time, and any  presentation of the Fund's total return for any prior period
should not be considered as a  representation  of what an investment may earn or
what the  Fund's  total  return  may be in any future  period.  If the  expenses
related to the  operation of the Fund or the  Portfolio  are  allocated to Eaton
Vance, the Fund's performance will be higher.

                      STATEMENT OF ADDITIONAL INFORMATION
                                    PART I
   
    This Part I provides  information about the Fund and certain other series of
the Trust.
    
               INVESTMENT  OBJECTIVE,  POLICIES AND  RESTRICTIONS
    The investment  objective of the Fund, a diversified series of the Trust, is
to achieve  capital  growth.  The Fund currently seeks to achieve its investment
objective by investing its assets in the Growth Portfolio (the  "Portfolio"),  a
separate registered investment company with the same investment objective as the
Fund and  substantially  the same  investment  policies and  restrictions as the
Fund. The Portfolio seeks to achieve its investment  objective by investing in a
carefully selected and continuously  managed portfolio  consisting  primarily of
equity securities.

    The  Trustees  of the Trust may  withdraw  the  Fund's  investment  from the
Portfolio at any time, if they determine that it is in the best interests of the
Fund to do so. Upon any such withdrawal,  the Fund's assets would be invested in
another  investment  company with  substantially the same investment  objective,
policies  and  restrictions  as  those  of the Fund or  directly  in  investment
securities in accordance with the Portfolio's  investment policies, as described
below.  Except as indicated below, the approval of the Fund's shareholders would
not be required to change the Portfolio's  investment  policies discussed below,
including those concerning security transactions.

    The Portfolio's  investment policy is flexible, and the Portfolio may invest
in all kinds of  domestic  and  foreign  companies  in seeking  to  achieve  its
objective of capital  growth.  Income is  subordinate  to growth;  however,  the
Portfolio  will earn dividend or interest  income to the extent that it receives
dividends  or  interest  from  its  investments.  As  in  any  investment  which
fluctuates in value, the management of the Portfolio cannot,  of course,  assure
the  achievement of this objective or eliminate  risk. It is believed,  however,
that  through  broad and  selective  diversification  and through  informed  and
discriminating  investment  supervision,  the risks of investing will be reduced
and the shareholder's opportunities for a rewarding participation in the capital
growth sought by the Portfolio will be enhanced.

   
    The  Portfolio  will  invest   primarily  in  common  stocks  or  securities
convertible into common stocks (including  convertible  debt). The Portfolio may
also  invest  in  other  securities  and  obligations  of all  kinds,  including
preferred stocks, warrants,  rights, bonds, repurchase agreements,  money market
instruments and other  evidences of  indebtedness.  The Portfolio's  holdings of
debt securities, preferred stocks, short-term obligations or cash would normally
be employed to provide a reserve for future equity purchases or when the adviser
believes a more defensive investment posture is warranted.
    

    It is the  policy  of the  Portfolio  to  diversify  its  investments  among
industries  and  accordingly  no  investment  shall  be made  which  will  cause
investments  in any one  industry  to exceed 25% of the  Portfolio's  assets (at
market).

    While it is not the policy of the Portfolio to trade  actively in securities
for quick profits,  the management will dispose of securities  without regard to
the time  they  have  been  held if such  action  seems  advisable,  subject  to
satisfaction of certain tax requirements.

   
FOREIGN SECURITIES.  Investing in securities issued by companies whose principal
business  activities are outside the United States may involve significant risks
not  present in domestic  investments.  For  example,  there is  generally  less
publicly available  information about foreign companies,  particularly those not
subject to the  disclosure  and  reporting  requirements  of the  United  States
securities laws. Foreign issuers are generally not bound by uniform  accounting,
auditing,  and  financial  reporting  requirements  and  standards  of  practice
comparable  to those  applicable  to domestic  issuers.  Investments  in foreign
securities  also involve the risk of possible  adverse  changes in investment or
exchange control regulations, expropriation or confiscatory taxation, limitation
on the removal of funds or other assets of the Portfolio, political or financial
instability  or  diplomatic  and other  developments  which  could  affect  such
investments.  Furthermore,  economies  of  particular  countries or areas of the
world may differ favorably or unfavorably from the economy of the United States.
It is  anticipated  that in most cases the best  available  market  for  foreign
securities will be on exchanges or in  over-the-counter  markets located outside
of the  United  States.  Foreign  stock  markets,  while  growing  in volume and
sophistication,  are generally  not as developed as those in the United  States,
and securities of some foreign issuers (particularly those located in developing
countries)  may be less liquid and more volatile  than  securities of comparable
U.S. companies. In addition,  foreign brokerage commissions are generally higher
than  commissions  on  securities  traded  in  the  United  States  and  may  be
non-negotiable.  In general, there is less overall governmental  supervision and
regulation of foreign securities  markets,  broker-dealers,  and issuers than in
the United States.
    

    Since  investments  in companies  whose  principal  business  activities are
located  outside of the United  States will  frequently  involve  currencies  of
foreign countries,  and since assets of the Portfolio may temporarily be held in
bank  deposits  in  foreign  currencies  during  the  completion  of  investment
programs,  the value of the assets of the Portfolio as measured in U.S.  dollars
may be affected favorably or unfavorably by changes in foreign currency exchange
rates and exchange  control  regulations.  The Portfolio may conduct its foreign
currency  exchange  transactions  on a spot (i.e.,  cash) basis at the spot rate
prevailing  in the foreign  currency  exchange  market or through  entering into
contracts  to  purchase or sell  foreign  currencies  at a future date (i.e.,  a
"forward  foreign currency  exchange"  contract or "forward"  contract).  It may
convert  currency  on a spot basis from time to time,  and  investors  should be
aware of the costs of currency conversion.  Although foreign exchange dealers do
not  charge  a fee for  conversion,  they  do  realize  a  profit  based  on the
difference  (the  "spread")  between  the  prices at which  they are  buying and
selling various currencies.  Thus, a dealer may offer to sell a foreign currency
to the Portfolio at one rate,  while  offering a lesser rate of exchange  should
the Portfolio  desire to resell that currency to the dealer.  Forward  contracts
are traded in the interbank market  conducted  directly between currency traders
(usually  large  commercial  banks)  and their  customers.  A  forward  contract
generally  has no deposit  requirement,  and no  commissions  are charged at any
stage for trades.  When the Portfolio enters into a contract for the purchase or
sale of a security denominated in a foreign currency, it may desire to "lock in"
the U.S. dollar price of the security.  By entering into a forward  contract for
the  purchase  or sale,  for a fixed  amount of U.S.  dollars,  of the amount of
foreign currency involved in the underlying security transaction,  the Portfolio
will be able to protect itself against a possible loss resulting from an adverse
change in the  relationship  between  the U.S.  dollar and the  subject  foreign
currency  during the period  between the date the  security is purchased or sold
and the date on which payment is made or received.  Although a forward  contract
will  minimize  the risk of loss due to a  decline  in the  value of the  hedged
currency,  it also limits any potential gain which might result should the value
of such currency increase.

   
STOCK INDEX FUTURES.  Entering into a derivative instrument involves a risk that
the applicable  market will move against the  Portfolio's  position and that the
Portfolio  will incur a loss.  This loss may  exceed  the amount of the  initial
investment made or the premium received by the Portfolio. Derivative instruments
may  sometimes  increase or leverage  the  Portfolio's  exposure to a particular
market risk. Leverage enhances the Portfolio's  exposure to the price volatility
of derivative  instruments it holds. The Portfolio's success in using derivative
instruments to hedge portfolio assets depends on the degree of price correlation
between the derivative  instruments and the hedged asset.  Imperfect correlation
may be caused by several factors,  including  temporary price  disparities among
the trading  markets for the derivative  instrument,  the assets  underlying the
derivative  instrument  and the  Portfolio's  assets.  During  periods of market
volatility,   a  commodity   exchange  may  suspend  or  limit   trading  in  an
exchange-traded  derivative instrument,  which may make the contract temporarily
illiquid and difficult to price.  Commodity  exchanges may also establish  daily
limits on the amount  that the price of a futures  contract  or futures can vary
from the previous day's settlement  price.  Once the daily limit is reached,  no
trades may be made that day at a price  beyond the limit.  This may  prevent the
Portfolio from closing out positions and limiting its losses. Certain provisions
of the Internal Revenue Code of 1986, as amended (the "Code"),  limit the extent
to which  the  Portfolio  may  purchase  and sell  derivative  instruments.  The
Portfolio will engage in transactions  in futures  contracts and related options
only to the extent such transactions are consistent with the requirements of the
Code for maintaining  the  qualification  of the Fund as a regulated  investment
company ("RIC") for Federal income tax purposes.

    Transactions using futures contracts and options thereon (other than options
that the  Portfolio  has  purchased)  expose the  Portfolio to an  obligation to
another party. The Portfolio will not enter into any such transactions unless it
owns either (1) an  offsetting  ("covered")  position in  securities  or futures
contracts,  or (2) cash, receivables and short-term debt securities with a value
sufficient  at all times to cover  its  potential  obligations  not  covered  as
provided in (1) above.  The Portfolio  will comply with  Securities and Exchange
Commission  guidelines  regarding  cover  for  these  instruments  and,  if  the
guidelines  so require,  set aside cash,  U.S.  Government  securities  or other
liquid, high-grade debt securities in a segregated account with its custodian in
the prescribed amount.

    Assets used as cover or held in a  segregated  account  cannot be sold while
the position in the  corresponding  futures  contract or option is open,  unless
they are replaced with other appropriate  assets. As a result, the commitment of
a large portion of the Portfolio's assets to cover or segregated  accounts could
impede  portfolio  management  or the  Portfolio's  ability  to meet  redemption
requests or other current obligations.

    The  Portfolio  may enter into  futures  contracts,  and  options on futures
contracts,  traded on an exchange  regulated by the Commodities  Futures Trading
Commission  ("CFTC")  and on foreign  exchanges,  but,  with  respect to foreign
exchange-traded futures contracts and options on such futures contracts, only if
the Investment  Adviser  determined  that trading on each such foreign  exchange
does not subject the Portfolio to risks,  including  credit and liquidity risks,
that  are  materially   greater  then  the  risks  associated  with  trading  on
CFTC-regulated exchanges.

REPURCHASE AGREEMENTS. The Portfolio may purchase U.S. Government securities and
concurrently  enter into  repurchase  agreements with the seller under which the
seller  agrees  to  repurchase  such  securities  at the  Portfolio's  cost plus
interest within a specified time (normally one day). While repurchase agreements
involve certain risks not associated with direct investments in U.S.  Government
securities,  the Portfolio follows  procedures  designed to minimize such risks.
These procedures  include  effecting  repurchase  transactions  only with large,
well-capitalized  banks. In addition, the Portfolio'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.  In the  event of a  default  or
bankruptcy  by a  selling  bank,  the  Portfolio  will  seek to  liquidate  such
collateral.  However,  the exercise of the  Portfolio's  right to liquidate such
collateral  could  involve  certain  costs or delays  and,  to the  extent  that
proceeds from any sale upon a default of the  obligation to repurchase  are less
than the repurchase price, the Portfolio could suffer a loss.

    The following investment  restrictions have been adopted by the Fund and may
be changed  only by the vote of a  majority  of the  Fund's  outstanding  voting
securities as defined in the Investment Company Act of 1940 (the "1940 Act").
    

    As a matter of  fundamental  investment  policy,  the Fund may not:

(1) With respect to 75% of the total assets of the Fund, purchase the securities
of any issuer if such  purchase at the time thereof  would cause more than 5% of
its total assets  (taken at market  value) to be invested in the  securities  of
such issuer,  or purchase  securities of any issuer if such purchase at the time
thereof would cause more than 10% of the total voting  securities of such issuer
to be held by the Fund,  except  obligations  issued or  guaranteed  by the U.S.
Government,  its agencies or  instrumentalities  and except  securities of other
investment companies;

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

(3)  Purchase  securities  on margin  (but the Fund may obtain  such  short-term
credits  as may be  necessary  for  the  clearance  of  purchase  and  sales  of
securities);

(4) Underwrite or participate in the marketing of securities of others;

(5) Make an  investment  in any one  industry  if such  investment  would  cause
investments in such industry to exceed 25% of the Fund's total assets, at market
value at the time of such investment (other than securities issued or guaranteed
by the U.S. Government or its agencies or instrumentalities);

(6) Purchase or sell real estate,  although it may purchase and sell  securities
which are secured by real estate and  securities  of  companies  which invest or
deal in real estate;

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

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

   
    Notwithstanding  the investment  policies and  restrictions of the Fund, the
Fund may invest its assets in an open-end  management  investment  company  with
substantially  the same investment  objective,  policies and restrictions as the
Fund.
    

    The Fund will not issue bonds,  debentures or senior equity securities,  and
this policy will not be changed unless  authorized by a vote of the shareholders
of the Fund.

   
    The  Portfolio has adopted  substantially  the same  fundamental  investment
restrictions as the foregoing numbered  investment  restrictions  adopted by the
Fund; such restrictions cannot be changed without the approval of a "majority of
the  outstanding  voting  securities"  of the  Portfolio,  which as used in this
Statement  of  Additional  Information  means  the  lesser  of  (a)  67%  of the
outstanding  voting  securities of the Portfolio present or represented by proxy
at a  meeting  if the  holders  of  more  than  50% of  the  outstanding  voting
securities  of the Portfolio  are present or  represented  at the meeting or (b)
more than 50% of the outstanding  voting  securities of the Portfolio.  The term
"voting  securities"  as used in this  paragraph  has the same meaning as in the
1940 Act.  Whenever the Trust is requested to vote on a change in the investment
restrictions  of  the  Portfolio,   the  Trust  will  hold  a  meeting  of  Fund
shareholders and will cast its vote as instructed by the shareholders.

    The Fund and the Portfolio  have each adopted the  following  nonfundamental
investment  policies  which  may be  changed  with  respect  to the  Fund by the
Trustees  of the Trust  without  approval by the Fund's  shareholders  or may be
changed with respect to the Portfolio by the Trustees of the  Portfolio  without
the  approval of the Fund or the  Portfolio's  other  investors.  As a matter of
nonfundamental  policy,  neither the Fund nor the  Portfolio  may:  (a) purchase
securities  of  companies  which,  including  predecessors,  have  not  been  in
continuous  operation  for at least  three  years,  except  that 5% of its total
assets  (taken at market  value) may be invested in such  companies and exempted
from this  restriction  are U.S.  Government  securities,  securities of issuers
which are  rated by at least  one  nationally  recognized  rating  organization,
municipal  obligations  and  obligations  issued or  guaranteed  by any  foreign
government or its agencies or  instrumentalities;  (b) purchase or retain in its
portfolio any securities  issued by an issuer any of whose officers,  directors,
trustees  or  security  holders  is an  officer  or  trustee of the Trust or the
Portfolio or is a member, officer, director or trustee of any investment adviser
of the Trust or the  Portfolio,  if after the purchase of the securities of such
issuer  by  the  Fund  or the  Portfolio  one  or  more  of  such  persons  owns
beneficially  more than 1/2 of 1% of the shares or securities or both (all taken
at market  value) of such issuer and such persons  owning more than 1/2 of 1% of
such shares or securities  together own beneficially more than 5% of such shares
or securities or both (all taken at market value);  (c) sell or contract to sell
any  security  which it does not own unless by virtue of its  ownership of other
securities it has at the time of sale a right to obtain securities equivalent in
kind and  amount  to the  securities  sold and  provided  that if such  right is
conditional the sale is made upon the same  conditions;  or (d) invest more than
15% of net assets in  investments  which are not readily  marketable,  including
restricted  securities  and  repurchase  agreements  maturing in more than seven
days.  Restricted  securities for the purposes of this limitation do not include
securities  eligible for resale  pursuant to Rule 144A of the  Securities Act of
1933 that the Board of Trustees of the Trust or the Portfolio,  or its delegate,
determine  to be  liquid,  based  upon  the  trading  markets  for the  specific
security.

    In order to permit  the sale of shares of the Fund in  certain  states,  the
Fund may make commitments  more  restrictive than the policies  described above.
Should  the Fund  determine  that any such  commitment  is no longer in the best
interests of the Fund and its  shareholders,  it will revoke the  commitment  by
terminating sales of its shares in the state(s) involved.

by the Portfolio in the shares of one or more funds in the Eaton Vance Family of
Funds,  and the amount paid to the  Trustees  under the Plan will be  determined
based upon the  performance of such  investments.  Deferral of Trustees' fees in
accordance  with the Plan  will  have a  negligible  effect  on the  Portfolio's
assets,  liabilities,  and net  income  per  share,  and will not  obligate  the
Portfolio to retain the services of any Trustee or obligate the Portfolio to pay
any particular level of compensation to the Trustee.

   
    For the compensation  earned by the noninterested  Trustees of the Trust and
the  Portfolio,  see  "Fees  and  Expenses"  in  Part II of  this  Statement  of
Additional Information.
    


                      INVESTMENT ADVISER AND ADMINISTRATOR
    The Portfolio engages BMR as its investment adviser pursuant to an
Investment  Advisory  Agreement dated August 1, 1994. BMR or Eaton Vance acts as
investment   adviser  to  investment   companies  and  various   individual  and
institutional clients with combined assets under management of approximately $15
billion.

    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 its 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.

    BMR manages the  investments  and  affairs of the  Portfolio  subject to the
supervision of the Portfolio's Board of Trustees. BMR furnishes to the Portfolio
investment research, advice and supervision, furnishes an investment program and
determines what securities will be purchased,  held or sold by the Portfolio and
what portion,  if any, of the Portfolio's  assets will be held  uninvested.  The
Investment  Advisory  Agreement requires BMR to pay the salaries and fees of all
officers and Trustees of the Portfolio  who are members of the BMR  organization
and all personnel of BMR performing services relating to research and investment
activities.  The Portfolio is responsible for all expenses not expressly  stated
to be payable by BMR under the Investment Advisory Agreement, including, without
implied limitation, (i) expenses of maintaining the Portfolio and continuing its
existence,  (ii)  registration  of the  Portfolio  under  the  1940  Act,  (iii)
commissions, fees and other expenses connected with the acquisition, holding and
disposition of securities and other investments,  (iv) auditing,  accounting and
legal expenses,  (v) taxes and interest,  (vi) governmental fees, (vii) expenses
of issue, sale and redemption of interests in the Portfolio,  (viii) expenses of
registering  and qualifying  the Portfolio and interests in the Portfolio  under
Federal and state  securities  laws and of preparing  and printing  registration
statements or other  offering  statements or memoranda for such purposes and for
distributing  the same to investors,  and fees and expenses of  registering  and
maintaining  registrations  of the  Portfolio and of the  Portfolio's  placement
agent as  broker-dealer  or agent under state  securities laws, (ix) expenses of
reports  and  notices  to  investors  and of  meetings  of  investors  and proxy
solicitations  therefor,  (x) expenses of reports to  governmental  officers and
commissions,  (xi) insurance expenses, (xii) association membership dues, (xiii)
fees,  expenses  and  disbursements  of  custodians  and  subcustodians  for all
services to the Portfolio  (including without  limitation  safekeeping of funds,
securities and other investments,  keeping of books,  accounts and records,  and
determination of net asset values, book capital account balances and tax capital
account  balances),  (xiv) fees,  expenses and disbursements of transfer agents,
dividend  disbursing  agents,  investor  servicing agents and registrars for all
services  to  the  Portfolio,  (xv)  expenses  for  servicing  the  accounts  of
investors, (xvi) any direct charges to investors approved by the Trustees of the
Portfolio, (xvii) compensation and expenses of Trustees of the Portfolio who are
not members of BMR's  organization,  and (xviii) such non-recurring items as may
arise,  including  expenses incurred in connection with litigation,  proceedings
and claims and the  obligation  of the  Portfolio  to  indemnify  its  Trustees,
officers and investors with respect thereto.

   
    Under the Investment  Advisory Agreement with the Portfolio,  BMR receives a
monthly  advisory fee of 5/96 of 1% (equivalent  to 0.625%  annually) of average
daily net assets of the Portfolio up to and including $300 million,  and 1/24 of
1% (equivalent to 0.50% annually) of average daily net assets over $300 million.
As at February 28, 1995, the Portfolio had net assets of  $122,814,547.  For the
period from the start of business,  August 2, 1994,  to February  28, 1995,  BMR
received  advisory fees of $384,275  (equivalent to 0.625%  (annualized)  of the
Portfolio's   average  daily  net  assets  for  such  period).   For  additional
information  about  the fees  paid to the  Investment  Adviser,  see  "Fees  and
Expenses" in Part II of this Statement of Additional Information.
    

    The Investment  Advisory Agreement with BMR remains in effect until February
28,  1996.  It  may  be  continued  indefinitely  thereafter  so  long  as  such
continuance  after  February  28, 1996 is approved at least  annually (i) by the
vote of a majority  of the  Trustees  of the  Portfolio  who are not  interested
persons  of the  Portfolio  or of BMR cast in person  at a meeting  specifically
called  for the  purpose  of  voting on such  approval  and (ii) by the Board of
Trustees of the  Portfolio  or by vote of a majority of the  outstanding  voting
securities of the Portfolio. The Agreement may be terminated at any time without
penalty on sixty days'  written  notice by the Board of Trustees of either party
or by  vote  of  the  majority  of  the  outstanding  voting  securities  of the
Portfolio,  and the Agreement will terminate  automatically  in the event of its
assignment.  The Agreement  provides that BMR may render  services to others and
may permit other fund clients and other  corporations  and  organizations to use
the words "Eaton Vance" or "Boston  Management and Research" in their names. The
Agreement  also  provides  that BMR shall not be liable for any loss incurred in
connection with the performance of its duties,  or action taken or omitted under
that  Agreement,  in the  absence  of  willful  misfeasance,  bad  faith,  gross
negligence  in the  performance  of its  duties  or by  reason  of its  reckless
disregard of its obligations and duties thereunder,  or for any losses sustained
in the acquisition, holding or disposition of any security or other investment.

   
    As indicated in the Prospectus,  Eaton Vance serves as  Administrator of the
Fund, but receives no compensation for providing  administrative services to the
Fund.  Under its  agreement  with the Fund,  Eaton  Vance  has been  engaged  to
administer the Fund's affairs, subject to the supervision of the Trustees of the
Trust,  and shall furnish for the use of the Fund office space and all necessary
office facilities,  equipment and personnel for administering the affairs of the
Fund.
    

    The Fund pays all of its own expenses  including,  without  limitation,  (i)
expenses of maintaining the Fund and continuing its existence, (ii) registration
of the Trust  under the 1940 Act,  (iii)  commissions,  fees and other  expenses
connected  with the purchase or sale of securities and other  investments,  (iv)
auditing,   accounting  and  legal  expenses,  (v)  taxes  and  interest,   (vi)
governmental fees, (vii) expenses of issue,  sale,  repurchase and redemption of
shares,  (viii)  expenses of registering  and qualifying the Fund and its shares
under  federal  and  state   securities  laws  and  of  preparing  and  printing
prospectuses for such purposes and for distributing the same to shareholders and
investors, and fees and expenses of registering and maintaining registrations of
the Fund and of the Fund's  principal  underwriter,  if any, as broker-dealer or
agent  under  state  securities  laws,  (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 Fund
(including  without  limitation  safekeeping  of  funds,  securities  and  other
investments,  keeping  of books  and  accounts  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 Fund, (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
Eaton Vance  organization,  and (xviii) 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 and officers
with respect thereto.

    A commitment has been made to a state securities  authority that Eaton Vance
will take certain  actions,  if necessary,  so that the Fund's expenses will not
exceed  expense  limitation  requirements  of such state.  The commitment may be
amended or rescinded  by Eaton Vance in response to changes in the  requirements
of the state or for other reasons.

   
    BMR is a wholly-owned subsidiary of Eaton Vance. Eaton Vance and EV are
both wholly-owned subsidiaries of EVC. BMR and Eaton Vance are both
Massachusetts business trusts, and EV is the trustee of BMR and Eaton Vance.
The Directors of EV are Landon T. Clay, H. Day Brigham, Jr., M. Dozier
Gardner, James B. Hawkes and Benjamin A. Rowland, Jr. The Directors of EVC
consist of the same persons and John G. L. Cabot and Ralph Z. Sorenson. Mr.
Clay is chairman, and Mr. Gardner is president and chief executive officer, of
EVC, BMR, Eaton Vance and EV. All of the issued and outstanding shares of
Eaton Vance and of EV are owned by EVC. All of the issued and outstanding
shares of BMR are owned by Eaton Vance. All shares of the outstanding Voting
Common Stock of EVC are deposited in a Voting Trust, which expires December
31, 1996, the Voting Trustees of which are Messrs. Brigham, Clay, Gardner,
Hawkes and Rowland. The Voting Trustees have unrestricted voting rights for
the election of Directors of EVC. All of the outstanding voting trust receipts
issued under said Voting Trust are owned by certain of the officers of BMR and
Eaton Vance who are also officers or Directors of EVC and EV. As of March 31,
1995, Messrs. Clay, Gardner and Hawkes each owned 24% of such voting trust
receipts, and Messrs. Rowland and Brigham owned 15% and 13%, respectively, of
such voting trust receipts. Messrs. Clay, Gardner, Hawkes and Otis, who are
officers or Trustees of the Trust and the Portfolio, are members of the EVC,
Eaton Vance, BMR and EV organizations. Messrs. Austin, Kiely, Murphy and
O'Connor and Ms. Sanders are officers of the Trust and the Portfolio and all
are also members of the BMR, Eaton Vance and EV organizations. BMR will
receive the fees paid under the Investment Advisory Agreement.

    Eaton Vance owns all of the stock of Energex  Corporation,  which is engaged
in oil and gas operations.  EVC owns all of the stock of Marblehead Energy Corp.
(which is engaged in oil and gas operations) and 77.3% of the stock of Investors
Bank & Trust  Company,  the  custodian  of the  Fund  and the  Portfolio,  which
provides custodial, trustee and other fiduciary services to investors, including
individuals, employee benefit plans, corporations, investment companies, savings
banks and other institutions.  In addition, Eaton Vance owns all of the stock of
Northeast  Properties,  Inc.,  which  is  engaged  in  real  estate  investment,
consulting and management. EVC owns all of the stock of Fulcrum Management, Inc.
and  MinVen,  Inc.,  which are  engaged in the  development  of  precious  metal
properties. EVC, BMR, Eaton Vance and EV may also enter into other businesses.

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

                                  CUSTODIAN
   
    Investors  Bank  &  Trust  Company  ("IBT"),  24  Federal  Street,   Boston,
Massachusetts,  (a 77.3% owned subsidiary of EVC) acts as custodian for the Fund
and the Portfolio.  IBT has the custody of all cash and securities  representing
the Fund's interest in the Portfolio, has custody of all the Portfolio's assets,
maintains the general  ledger of the  Portfolio  and the Fund,  and computes the
daily net asset value of interests in the  Portfolio  and the net asset value of
shares of the Fund. In such  capacity it attends to details in  connection  with
the  sale,  exchange,   substitution,   transfer  or  other  dealings  with  the
Portfolio's investments,  receives and disburses all funds, and performs various
other ministerial  duties upon receipt of proper  instructions from the Fund and
the Portfolio.  IBT charges fees which are believed to be competitive within the
industry.  A portion of the fee relates to  custody,  bookeeping  and  valuation
services and is based upon a percentage  of Fund and  Portfolio net assets and a
portion  of the fee  relates  to  activity  charges,  primarily  the  number  of
portfolio  transactions.  These  fees are  then  reduced  by a  credit  for cash
balances of the particular  investment  company at the custodian equal to 75% of
the 91-day, U.S. Treasury Bill auction rate applied to the particular investment
company's  average  daily  collected  balances  for  the  week.  In  view of the
ownership of EVC in IBT, the Portfolio is treated as a  self-custodian  pursuant
to Rule 17f-2 under the 1940 Act, and the Portfolio's investments held by IBT as
custodian  are  thus  subject  to  additional  examinations  by the  Portfolio's
independent  auditors as called for by such Rule.  For the period from the start
of  business,  August 2, 1994,  to February  28, 1995,  the  Portfolio  paid IBT
$37,310. For the custody fees that the Fund paid to IBT, see "Fees and Expenses"
in Part II of this Statement of Additional Information.
    
                             SERVICE FOR WITHDRAWAL
   
    By a  standard  agreement,  the  Trust's  Transfer  Agent  will  send to the
shareholder  regular  monthly or  quarterly  payments  of any  permitted  amount
designated  by  the  shareholder  (see  "Eaton  Vance  Shareholder  Services  --
Withdrawal Plan" in the Fund's current  Prospectus)  based upon the value of the
shares  held.  The checks will be drawn from share  redemptions  and hence are a
return  of  principal.  Income  dividends  and  capital  gain  distributions  in
connection  with  withdrawal  accounts will be credited at net asset value as of
the  record  date for each  distribution.  Continued  withdrawals  in  excess of
current  income will  eventually use up principal,  particularly  in a period of
declining market prices.

    To use this  service,  at  least  $5,000  in cash or  shares  at the  public
offering  price  will  have  to  be  deposited  with  the  Transfer  Agent.  The
maintenance of a withdrawal plan  concurrently with purchases of additional Fund
shares would be disadvantageous if a sales charge is included in such purchases.
A  shareholder  may not have a withdrawal  plan in effect at the same time he or
she has  authorized  Bank  Automated  Investing or is otherwise  making  regular
purchases  of Fund shares.  Either the  shareholder,  the Transfer  Agent or the
Principal  Underwriter will be able to terminate the withdrawal plan at any time
without penalty.
    

                       DETERMINATION  OF NET ASSET  VALUE
   
    The net asset value of the shares of the Fund is determined by IBT (as agent
and custodian for the Fund) in the manner  described under "Valuing Fund Shares"
in the Fund's current Prospectus.  The Fund and the Portfolio will be closed for
business  and will  not  price  their  respective  shares  or  interests  on the
following business holidays: New Year's Day, Presidents' Day, Good Friday (a New
York  Stock  Exchange  holiday),  Memorial  Day,  Independence  Day,  Labor Day,
Thanksgiving Day and Christmas Day.

    Securities  listed on securities  exchanges or in the NASDAQ National Market
are valued at closing  sale  prices.  Unlisted  or listed  securities  for which
closing sale prices are not  available are valued at the mean between the latest
bid  and  asked  prices.   Fixed-income   securities   (other  than   short-term
obligations),  including  listed  securities  and  securities  for  which  price
quotations  are  available,  will  normally  be  valued  on the  basis of market
valuations  furnished by a pricing service. The pricing service uses information
with respect to  transactions  in bonds,  quotations  from bond dealers,  market
transactions in comparable securities, various relationships between securities,
and yield to maturity in determining value.  Short-term  obligations maturing in
sixty days or less are valued at  amortized  cost,  which  approximates  market.
Foreign  securities  are valued in U.S.  Dollars at the current  exchange  rate.
Other assets are valued at fair value using methods  determined in good faith by
the Trustees.
    

    Each investor in the Portfolio, including the Fund, may add to or reduce its
investment  in the  Portfolio  on each  day the New  York  Stock  Exchange  (the
"Exchange")  is open for trading  ("Portfolio  Business Day") as of the close of
regular trading on the Exchange (the "Portfolio  Valuation Time").  The value of
each investor's  interest in the Portfolio will be determined by multiplying the
net asset value of the  Portfolio  by the  percentage,  determined  on the prior
Portfolio Business Day, which represented that investor's share of the aggregate
interests in the Portfolio on such prior day. Any additions or  withdrawals  for
the  current  Portfolio  Business  Day will then be  recorded.  Each  investor's
percentage of the aggregate interest in the Portfolio will then be recomputed as
a percentage equal to a fraction (i) the numerator of which is the value of such
investor's investment in the Portfolio as of the Portfolio Valuation Time on the
prior  Portfolio  Business Day plus or minus,  as the case may be, the amount of
any additions to or withdrawals from the investor's  investment in the Portfolio
on the current  Portfolio  Business Day and (ii) the denominator of which is the
aggregate net asset value of the Portfolio as of the Portfolio Valuation Time on
the prior  Portfolio  Business Day plus or minus, as the case may be, the amount
of the net  additions to or  withdrawals  from the  aggregate  investment in the
Portfolio  on  the  current  Portfolio  Business  Day by  all  investors  in the
Portfolio.  The  percentage so determined  will then be applied to determine the
value of the  investor's  interest in the  Portfolio  for the current  Portfolio
Business Day.

                            INVESTMENT PERFORMANCE
   
    The average  annual total return is determined by multiplying a hypothetical
initial  purchase order of $1,000 by the average annual  compound rate of return
(including  capital  appreciation/depreciation,  and dividends and distributions
paid and  reinvested)  for the stated period and, if necessary,  annualizing the
result.  The calculation  assumes that all dividends from net investment  income
and  capital  gain  distributions  are  reinvested  at net  asset  value  on the
reinvestment  dates  during the period  (and  either  (i) the  deduction  of the
maximum sales charge from the initial $1,000  purchase order, or (ii) a complete
redemption of the investment and, if applicable, the deduction of any contingent
deferred sales charge at the end of the period). For information  concerning the
total  return  of the Fund,  see  "Performance  Information"  in Part II of this
Statement of Additional Information.

    The Fund's  total  return may be  compared to the  Consumer  Price Index and
various domestic  securities indices,  for example:  Standard & Poor's 400 Stock
Index,  Standard & Poor's 500 Stock Index,  Merrill Lynch U.S. Treasury (15-year
plus) Index, Lehman Brothers  Government/Corporate Bond Index, and the Dow Jones
Industrial  Average.  The Fund's total return and comparisons with these indices
may be used  in  advertisements  and in  information  furnished  to  present  or
prospective  shareholders.  The Fund's performance may differ from that of other
investors in the Portfolio, including any other investment companies.

    Information used in advertisements and in materials  furnished to present or
prospective  shareholders may include  statistics,  data and performance studies
prepared by independent  organizations,  (e.g., Ibbotson Associates,  Standard &
Poor's Ratings Group,  Merrill Lynch, Pierce,  Fenner & Smith, Inc.,  Bloomberg,
L.P., Dow Jones & Company,  Inc., and The Federal  Reserve Board) or included in
various  publications  (e.g., The Wall Street Journal,  Barron's and The Decade:
Wealth of Investments in U.S. Stocks,  Bonds, Bills & Inflation)  reflecting the
investment  performance  or return  achieved  by  various  classes  and types of
investments  (e.g.,  common stocks,  small company stocks,  long-term  corporate
bonds,  long-term  government  bonds,  intermediate-term  government bonds, U.S.
Treasury bills) over various  periods of time.  This  information may be used to
illustrate the benefits of long-term investments in common stocks.

Information.
    
                                    TAXES
    See   "Distributions  and  Taxes"  in  the  Fund's  current  Prospectus  and
"Additional Tax Matters" in Part II of this Statement of Additional Information.

   
    Each series of the Trust is treated as a separate  entity for Federal income
tax purposes. The Fund will elect to be treated and intends to qualify each year
as a RIC  under the Code.  Accordingly,  the Fund  intends  to  satisfy  certain
requirements relating to sources of its income and diversification of its assets
and to distribute  its net investment  income and net realized  capital gains in
accordance with the timing requirements  imposed by the Code, so as to avoid any
Federal income or excise tax to the Fund. Because the Fund invests its assets in
the  Portfolio,  the Portfolio  normally must satisfy the  applicable  source of
income and  diversification  requirements in order for the Fund to satisfy them.
The Portfolio will allocate at least annually among its investors, including the
Fund, the Portfolio's net investment income, net realized capital gains, and any
other items of income,  gain, loss, deduction or credit. The Portfolio will make
allocations to the Fund in accordance  with the Code and applicable  regulations
and will make  moneys  available  for  withdrawal  at  appropriate  times and in
sufficient   amounts  to  enable  the  Fund  to  satisfy  the  tax  distribution
requirements that apply to the Fund and that must be satisfied in order to avoid
Federal  income  and/or  excise tax on the Fund.  For  purposes of applying  the
requirements  of the Code  regarding  qualification  as a RIC,  the Fund will be
deemed (i) to own its proportionate share of each of the assets of the Portfolio
and (ii) to be entitled to the gross  income of the  Portfolio  attributable  to
such share.

    In  order to avoid  Federal  excise  tax,  the Code  requires  that the Fund
distribute  (or be deemed to have  distributed)  by December 31 of each calendar
year at least 98% of its ordinary income (not including  tax-exempt  income) for
such year, and at least 98% of the excess of its realized capital gains over its
realized capital losses,  generally computed on the basis of the one-year period
ending on October  31 of such year or, by  election,  December  31 of such year,
after  reduction by any available  capital loss  carryforwards,  and 100% of any
income from the prior year (as previously computed) that was not paid out during
such year and on which the Fund was not taxed.

    Under  current law,  provided  that the Fund  qualifies as a RIC for Federal
income  tax  purposes  and  the  Portfolio  is  treated  as  a  partnership  for
Massachusetts  and Federal tax  purposes,  neither the Fund nor the Portfolio is
liable  for  any  income,  excise  or  franchise  tax  in  the  Commonwealth  of
Massachusetts.

    Foreign  exchange  gains and losses  realized by the Portfolio in connection
with investments in foreign  securities and forward  contracts may be treated as
ordinary income and losses under special tax rules. Certain forward contracts of
the Portfolio may be required to be marked to market (i.e., treated as if closed
out) on the last day of each taxable  year,  and any gain or loss  realized with
respect to these  contracts  may be required to be treated as 60%  long-term and
40% short-term  gain or loss.  Positions of the Portfolio in foreign  securities
and offsetting forward contracts may be treated as "straddles" and be subject to
other  special  rules that may  affect  the  amount,  timing  and  character  of
Portfolio  distributions to  shareholders.  The Portfolio will limit its foreign
currency   hedging   activities   to  the  extent   necessary  to  preserve  its
qualification as a RIC.

    The Portfolio may be subject to foreign  withholding  or other foreign taxes
with respect to income  (possibly  including,  in some cases,  capital gains) on
certain foreign  securities.  These taxes may be reduced or eliminated under the
terms of an applicable U.S.  income tax treaty.  As it is not expected that more
than 50% of the value of the total  assets of the Fund,  taking into account its
allocable  share of the  Portfolio's  total assets,  at the close of any taxable
year of the Fund will consist of securities issued by foreign corporations,  the
Fund will not be eligible to pass through to  shareholders  their  proportionate
share of any foreign taxes paid by the Portfolio and allocated to the Fund, with
the  result  that  shareholders  will not  include  in  income,  and will not be
entitled to take any foreign tax credits or deductions  for,  foreign taxes paid
by the Portfolio and allocated to the Fund. Certain uses of foreign currency and
investments by the Portfolio in the stock of certain "passive foreign investment
companies" may be limited or a tax election may be made, if available,  in order
to preserve the Fund's  qualification  as a RIC and/or to avoid  imposition of a
tax on the Fund.

    A portion of distributions made by the Fund which are derived from dividends
received by the Portfolio from domestic  corporations  and allocated to the Fund
may  qualify  for  the  dividends-received   deduction  for  corporations.   The
dividends-received deduction for corporate shareholders is reduced to the extent
the shares of the Fund with  respect to which the  dividends  are  received  are
treated as  debt-financed  under the Federal income tax law and is eliminated if
the  shares  are  deemed  to have  been  held for less  than a  minimum  period,
generally 46 days. Receipt of certain distributions qualifying for the deduction
may result in reduction of the tax basis of the corporate shareholder's shares.
    

    Distributions  of the  excess  of  net  long-term  capital  gains  over  net
short-term  capital losses  (including  any capital losses carried  forward from
prior years)  earned by the  Portfolio  and allocated to the Fund are taxable to
shareholders of the Fund as long-term capital gains, whether received in cash or
in additional shares and regardless of the length of time their shares have been
held. Certain distributions  declared in October,  November or December and paid
the following  January will be taxed to  shareholders as if received on December
31 of the year in which they are declared.

    Distributions of the Fund (including a portion of any distributions eligible
for  the  dividends-received   deduction)  may  give  rise  to  or  increase  an
alternative  minimum tax for  individuals  and  corporations  depending upon the
shareholder's particular tax situation.

   
    Any loss realized upon the redemption or exchange of shares of the Fund with
a tax holding period of 6 months or less will be treated as a long-term  capital
loss to the  extent of any  distribution  of net  long-term  capital  gains with
respect to such shares.  In addition,  all or a portion of a loss  realized on a
redemption or other  disposition  of Fund shares may be  disallowed  under "wash
sale" rules if other Fund shares are acquired  (whether through  reinvestment of
dividends or otherwise)  within a period  beginning 30 days before and ending 30
days after the date of such redemption or other disposition. Any disallowed loss
will result in an  adjustment to the  shareholder's  tax basis in some or all of
the other shares acquired.

    Special tax rules apply to Individual Retirement Accounts ("IRAs") and other
retirement plans and persons investing through IRAs or such plans should consult
their tax advisers for more information.
    

    Amounts paid by the Fund to individuals and certain other  shareholders  who
have not provided the Fund with their correct taxpayer identification number and
certain required  certifications,  as well as shareholders  with respect to whom
the Fund has  received  notification  from the  Internal  Revenue  Service  or a
broker,  may be subject to "backup"  withholding  of Federal income tax from the
Fund's dividends and  distributions  and the proceeds of redemptions  (including
repurchases  and  exchanges)  at  a  rate  of  31%.  An  individual's   taxpayer
identification number is generally his or her social security number.

    Non-resident  alien  individuals and certain foreign  corporations and other
foreign entities  generally will be subject to a U.S.  withholding tax at a rate
of 30% on the Fund's  distributions  from its ordinary  income and the excess of
its net short-term  capital gain over its net long-term capital loss, unless the
tax is reduced or eliminated by an applicable tax treaty. Distributions from the
excess of the Fund's net long-term capital gain over its net short-term  capital
loss  received  by such  shareholders  and  any  gain  from  the  sale or  other
disposition of shares of the Fund generally will not be subject to U.S.  Federal
income taxation,  provided that non-resident  alien status has been certified by
the  shareholder.  Different U.S. tax consequences may result if the shareholder
is engaged in a trade or business in the United States, is present in the United
States for a sufficient  period of time during a taxable year to be treated as a
U.S. resident, or fails to provide any required certifications  regarding status
as a non-resident alien investor.  Foreign shareholders should consult their tax
advisers regarding the U.S. and foreign tax consequences of an investment in the
Fund.

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

                       PORTFOLIO SECURITY TRANSACTIONS
    Decisions concerning the execution of portfolio security transactions of the
Portfolio, including the selection of the market and the broker-dealer firm, are
made by BMR. BMR is also  responsible for the execution of transactions  for all
other accounts managed by it.

    BMR places  the  security  transactions  of the  Portfolio  and of all other
accounts managed by it for execution with many broker-dealer firms. BMR uses its
best efforts to obtain  execution of portfolio  transactions at prices which are
advantageous to the Portfolio and (when a disclosed commission is being charged)
at reasonably competitive commission rates. In seeking such execution,  BMR will
use its best judgment in evaluating  the terms of a  transaction,  and will give
consideration to various relevant factors, including without limitation the size
and type of the transaction,  the general execution and operational capabilities
of the  broker-dealer,  the nature and character of the market for the security,
the confidentiality, speed and certainty of effective execution required for the
transaction, the reputation,  reliability, experience and financial condition of
the   broker-dealer,   the  value  and  quality  of  services  rendered  by  the
broker-dealer in other  transactions,  and the reasonableness of the commission,
if  any.  Transactions  on  United  States  stock  exchanges  and  other  agency
transactions  involve  the  payment by the  Portfolio  of  negotiated  brokerage
commissions.  Such commissions vary among different  broker-dealer  firms, and a
particular  broker-dealer  may charge  different  commissions  according to such
factors as the difficulty and size of the transaction and the volume of business
done with such broker-dealer. Transactions in foreign securities usually involve
the payment of fixed  brokerage  commissions,  which are  generally  higher than
those in the United States.  There is generally no stated commission in the case
of  securities  traded in the  over-the-counter  markets,  but the price paid or
received by the  Portfolio  usually  includes an  undisclosed  dealer  markup or
markdown.  In an  underwritten  offering the price paid by the  Portfolio  often
includes a disclosed fixed commission or discount retained by the underwriter or
dealer.  Although  commissions paid on portfolio security  transactions will, in
the  judgment of BMR,  be  reasonable  in relation to the value of the  services
provided,  commissions  exceeding  those which  another firm might charge may be
paid to  broker-dealers  who were selected to execute  transactions on behalf of
the  Portfolio  and BMR's  other  clients in part for  providing  brokerage  and
research services to BMR.

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

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

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

   
    Securities   considered  as  investments  for  the  Portfolio  may  also  be
appropriate for other investment accounts managed by BMR or its affiliates.  BMR
will attempt to allocate  equitably  portfolio  security  transactions among the
Portfolio and the portfolios of its other investment accounts whenever decisions
are made to purchase or sell securities by the Portfolio and one or more of such
other accounts simultaneously.  In making such allocations,  the main factors to
be considered are the respective investment objectives of the Portfolio and such
other  accounts,  the  relative  size  of  portfolio  holdings  of the  same  or
comparable securities,  the availability of cash for investment by the Portfolio
and such  accounts,  the size of investment  commitments  generally  held by the
Portfolio  and such  accounts  and the opinions of the persons  responsible  for
recommending  investments  to  the  Portfolio  and  such  accounts.  While  this
procedure  could  have a  detrimental  effect  on the  price  or  amount  of the
securities  available to the  Portfolio  from time to time, it is the opinion of
the Trustees of the Trust and the Portfolio that the benefits available from the
BMR  organization  outweigh  any  disadvantage  that may arise from  exposure to
simultaneous transactions.  For the period from the start of business, August 2,
1994, to February 28, 1995, the Portfolio paid brokerage  commissions of $92,370
on portfolio securities  transactions.  Of the total brokerage commissions paid,
approximately  $86,370 was paid in respect of portfolio securities  transactions
aggregating  approximately  $52,537,102  to firms which  provided  some Research
Services  to BMR  (although  many of such  firms may have been  selected  in any
particular transaction primarily because of their execution capabilities).
    

                              OTHER INFORMATION
   
    On August 18, 1992 the Trust  changed its name from Eaton Vance  Growth Fund
to Eaton  Vance  Growth  Trust.  The  Trust is a  Massachusetts  business  trust
established  in 1989 as the  successor  to Eaton  Vance  Growth  Fund,  Inc.,  a
Massachusetts  corporation,  which changed its name from Vance,  Sanders  Common
Stock Fund,  Inc. on November 16, 1981. Such name was changed from Boston Common
Stock Fund, Inc. on December 29, 1972. It was originally organized as a Canadian
corporation  in 1954, at which time it was known as Canada General Fund Limited.
Eaton Vance,  pursuant to its agreement with the Trust,  controls the use of the
words "Eaton  Vance" in the Trust's name and may use the words "Eaton  Vance" in
other connections and for other purposes.

    The  Trust's  Declaration  of Trust  may be  amended  by the  Trustees  when
authorized  by vote of a majority of the  outstanding  voting  securities of the
Trust affected by the amendment.  The Trustees may also amend the Declaration of
Trust  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  or if they deem it  necessary  to
conform the  Declaration  to the  requirements  of  applicable  Federal  laws or
regulations.  The  Trust's  by-laws  provide  that the Fund will  indemnify  its
Trustees and officers  against  liabilities and expenses  incurred in connection
with any litigation or proceeding in which they may be involved because of their
offices  with the Trust.  However,  no  indemnification  will be provided to any
Trustee or officer for any liability to the Trust or its  shareholders by reason
of willful misfeasance, bad faith, gross negligence or reckless disregard of the
duties involved in the conduct of his office.

    Under  Massachusetts law, if certain conditions  prevail,  shareholders of a
Massachusetts  business  trust  (such  as the  Trust)  could be  deemed  to have
personal  liability  for  the  obligations  of the  Trust.  Numerous  investment
companies  registered  under  the 1940 Act have  been  formed  as  Massachusetts
business trusts, and management is not aware of an instance where such liability
has  been  imposed.  The  Trust's  Declaration  of  Trust  contains  an  express
disclaimer  of  liability on the part of the Fund  shareholders  and the Trust's
By-laws  provide  that the Trust shall  assume the defense on behalf of any Fund
shareholders. Moreover, the Trust's By-laws also provide for indemnification out
of the property of the Fund of any shareholder held personally  liable solely by
reason of being or having  been a  shareholder  for all loss or expense  arising
from such  liability.  The assets of the Fund are  readily  marketable  and will
ordinarily  substantially exceed its liabilities.  In light of the nature of the
Fund's  business  and the nature of its  assets,  management  believes  that the
possibility  of the Fund's  liability  exceeding  its assets,  and therefore the
shareholder's risk of personal liability, is extremely remote.

    As permitted by  Massachusetts  law,  there will  normally be no meetings of
shareholders for the purpose of electing  Trustees unless and until such time as
less than a majority  of the  Trustees  of the Trust  holding  office  have been
elected by shareholders.  In such an event the Trustees then in office will call
a shareholders'  meeting for the election of Trustees.  Except for the foregoing
circumstances  and unless  removed by action of the  shareholders  in accordance
with the Trust's  By-laws,  the Trustees  shall  continue to hold office and may
appoint successor Trustees.

    The  Trust's  By-laws  provide  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 By-laws further provide
that under certain circumstances the shareholders may call a meeting to remove a
Trustee and that the Trust is required to provide  assistance  in  communicating
with shareholders about such a meeting.

    In accordance  with the  Declaration of Trust of the  Portfolio,  there will
normally be no meetings of the  investors  for the purpose of electing  Trustees
unless  and until  such time as less than a  majority  of the  Trustees  holding
office  have been  elected by  investors.  In such an event the  Trustees of the
Portfolio  then in office will call an  investors'  meeting for the  election of
Trustees. Except for the foregoing circumstances and unless removed by action of
the investors in  accordance  with the  Portfolio's  Declaration  of Trust,  the
Trustees shall continue to hold office and may appoint successor Trustees.
    

    The  Declaration  of Trust of the  Portfolio  provides  that no person shall
serve as a Trustee if investors holding  two-thirds of the outstanding  interest
have removed him from that office either by a written declaration filed with the
Portfolio's custodian or by votes cast at a meeting called for that purpose. The
Declaration  of Trust  further  provides that under  certain  circumstances  the
investors  may call a  meeting  to remove a Trustee  and that the  Portfolio  is
required to provide  assistance in  communicating  with  investors  about such a
meeting.

    The right to redeem  shares of the Fund can be suspended  and the payment of
the  redemption  price  deferred  when the  Exchange  is closed  (other than for
customary  weekend and holiday  closings),  during  periods  when trading on the
Exchange is restricted as determined by the Securities and Exchange  Commission,
or  during  any  emergency  as  determined  by the  Commission  which  makes  it
impracticable  for the  Portfolio  to  dispose  of its  securities  or value its
assets,  or during any other period permitted by order of the Commission for the
protection of investors.

                     STATEMENT OF ADDITIONAL INFORMATION

                                   PART II

     This Part II provides  information  about EV MARATHON GROWTH FUND. The Fund
became a series of the Trust on July 27, 1994.

                              FEES AND EXPENSES
ADMINISTRATOR
    As stated under  "Investment  Adviser and  Administrator"  in Part I of this
Statement of Additional Information,  the Administrator receives no compensation
for providing administrative services to the Fund. For the period from the start
of  business,  September  13, 1994,  to February 28, 1995,  $6,234 of the Fund's
operating  expenses were allocated on a preliminary basis to the  Administrator.

DISTRIBUTION PLAN
   
    For the period from the start of business,  September  13, 1994, to February
28,  1995,  the  Fund  made  sales  commission  payments  under  the Plan to the
Principal Underwriter aggregating $1,278, which amount was used by the Principal
Underwriter to partially defray sales commissions aggregating $5,401 paid during
such period by the Principal  Underwriter  to Authorized  Firms on sales of Fund
shares.  During such  period,  contingent  deferred  sales  charges  aggregating
approximately $837 were imposed on early redeeming  shareholders and paid to the
Principal Underwriter to partially defray sales commissions.  As at February 28,
1995,  the  outstanding   uncovered   distribution   charges  of  the  Principal
Underwriter  calculated under the Plan amounted to approximately  $27,052 (which
amount was  equivalent  to 3.7% of the  Fund's net assets on such day).  For the
period from the start of business, September 13, 1994, to February 28, 1995, the
Fund made no service  fee  payments  under the Plan.  The Fund  expects to begin
accruing for its service fee  payments  during the quarter  ending  December 31,
1995.
    

PRINCIPAL UNDERWRITER
   
    For the period from the start of business, September 13, 1994, to February
28, 1995, the Fund paid the Principal Underwriter $10.00 for repurchase
transactions handled (being $2.50 for each such transaction).
    

CUSTODIAN
     For the period from the start of business,  September 13, 1994, to February
28, 1995, the Fund paid IBT $583.

TRUSTEES
   
    The fees and  expenses of those  Trustees of the Trust and of the  Portfolio
who are not members of the Eaton Vance organization (the noninterested Trustees)
are paid by the Fund (and the  other  series of the  Trust)  and the  Portfolio,
respectively.  (The  Trustees of the Trust and the  Portfolio who are members of
the  Eaton  Vance  organization  receive  no  compensation  from the Fund or the
Portfolio.)  During the fiscal year ending  August 31, 1995,  it is  anticipated
that the  noninterested  Trustees of the Trust and the  Portfolio  will earn the
following  compensation  in their  capacities  as Trustees from the Fund and the
Portfolio,  and,  during the quarter  ended March 31,  1995,  the  noninterested

\1/ The Eaton Vance fund complex consists of 201 registered investment companies
    or series thereof.
    

                            PRINCIPAL UNDERWRITER
    Under the Distribution Agreement the Principal Underwriter acts as principal
in selling shares of the Fund. The expenses of printing  copies of  prospectuses
used to  offer  shares  to  Authorized  Firms or  investors  and  other  selling
literature and of advertising  is borne by the Principal  Underwriter.  The fees
and expenses of qualifying and registering and  maintaining  qualifications  and
registrations of the Fund and its shares under Federal and state securities laws
is borne by the Fund.  In  addition,  the Fund makes  payments to the  Principal
Underwriter pursuant to its Distribution Plan as described in the Fund's current
Prospectus; the provisions of the plan relating to such payments are included in
the Distribution Agreement.  The Distribution Agreement is renewable annually by
the Trust's Board of Trustees  (including a majority of its Trustees who are not
interested  persons  of the Trust and who have no direct or  indirect  financial
interest in the operation of the Fund's  Distribution  Plan or the  Distribution
Agreement),  may be  terminated on sixty days' notice either by such Trustees or
by vote of a majority of the outstanding voting securities of the Fund or on six
months' notice by the Principal Underwriter and is automatically terminated upon
assignment.  The  Principal  Underwriter  distributes  Fund  shares  on a  "best
efforts"  basis  under which it is required to take and pay for only such shares
as may be sold.

    The Fund has  authorized  Eaton Vance  Distributors,  Inc.  (the  "Principal
Underwriter")  to act as its agent in  repurchasing  shares at the rate of $2.50
for each  repurchase  transaction  handled  by the  Principal  Underwriter.  The
Principal  Underwriter  estimates that the expenses  incurred by it in acting as
repurchase agent for the Fund will exceed the amounts paid therefor by the Fund.

                              DISTRIBUTION PLAN
    The  Distribution  Plan ("the Plan") is described in the  Prospectus  and is
designed to meet the requirements of Rule 12b-1 under the 1940 Act and the sales
charge rule of the National  Association of Securities Dealers,  Inc. (the "NASD
Rule").  The purpose of the Plan is to compensate the Principal  Underwriter for
its  distribution  services  and  facilities  provided to the Fund by paying the
Principal  Underwriter  sales  commissions  and a separate  distribution  fee in
connection with sales of Fund shares.  The following  supplements the discussion
of the Plan contained in the Fund's Prospectus.

   
    The amount payable by the Fund to the Principal  Underwriter pursuant to the
Plan as sales commissions and distribution fees with respect to each day will be
accrued on such day as a liability of the Fund and will  accordingly  reduce the
Fund's net assets upon such accrual,  all in accordance with generally  accepted
accounting  principles.  The  amount  payable on each day is limited to 1/365 of
.75% of the Fund's  net  assets on such day.  The level of the Fund's net assets
changes  each day and depends upon the amount of sales and  redemptions  of Fund
shares,  the changes in the value of the investments held by the Portfolio,  the
expenses of the Fund and the Portfolio accrued and allocated to the Fund on such
day, income on portfolio  investments of the Portfolio  accrued and allocated to
the Fund on such day,  and any  dividends  and  distributions  declared  on Fund
shares.  The Fund does not accrue possible future payments as a liability of the
Fund or reduce the Fund's current net assets in respect of unknown amounts which
may  become  payable  under the Plan in the future  because  the  standards  for
accrual of a liability under such accounting principles have not been satisfied.

    The Plan provides that the Fund will receive all  contingent  deferred sales
charges and will make no payments to the Principal Underwriter in respect of any
day on which  there are no  outstanding  uncovered  distribution  charges of the
Principal  Underwriter.  Contingent  deferred sales charges and accrued  amounts
will be paid by the  Fund to the  Principal  Underwriter  whenever  there  exist
uncovered distribution charges under the Plan.

    Periods with a high level of sales of Fund shares accompanied by a low level
of early  redemptions  of Fund shares  resulting in the imposition of contingent
deferred  sales  charges  will tend to increase the time during which there will
exist uncovered distribution charges of the Principal  Underwriter.  Conversely,
periods with a low level of sales of Fund shares  accompanied by a high level of
early  redemptions  of Fund shares  resulting in the  imposition  of  contingent
deferred  sales  charges  will tend to reduce the time  during  which there will
exist uncovered distribution charges of the Principal Underwriter.
    

    In  calculating  daily  the  amount  of  uncovered   distribution   charges,
distribution  charges will include the aggregate amount of sales commissions and
distribution   fees   theretofore  paid  plus  the  aggregate  amount  of  sales
commissions and distribution fees which the Principal Underwriter is entitled to
be paid under the Plan since its inception. Payments theretofore paid or payable
under the Plan by the Fund to the Principal  Underwriter and contingent deferred
sales charges  theretofore paid or payable to the Principal  Underwriter will be
subtracted from such distribution  charges; if the result of such subtraction is
positive,  a distribution  fee (computed at 1% over the prime rate then reported
in The Wall Street  Journal) will be computed on such amount and added  thereto,
with  the  resulting  sum  constituting  the  amount  of  outstanding  uncovered
distribution  charges  with  respect  to such day.  The  amount  of  outstanding
uncovered  distribution charges of the Principal  Underwriter  calculated on any
day does not constitute a liability recorded on the financial  statements of the
Fund.

   
    The amount of uncovered distribution charges of the Principal Underwriter at
any particular time depends upon various changing  factors,  including the level
and timing of sales of Fund shares, the nature of such sales (i.e., whether they
result from  exchange  transactions,  reinvestments  or from cash sales  through
Authorized Firms), the level and timing of redemptions of Fund shares upon which
a  contingent  deferred  sales  charge will be imposed,  the level and timing of
redemptions  of Fund shares upon which no contingent  deferred sales charge will
be imposed (including  redemptions involving exchanges of Fund shares for shares
of another  fund in the Eaton Vance  Marathon  Group of Funds which  result in a
reduction of uncovered  distribution  charges),  changes in the level of the net
assets of the Fund, and changes in the interest rate used in the  calculation of
the distribution fee under the Plan.

    As currently  implemented by the Trustees,  the Plan authorizes  payments of
sales commissions and distribution fees to the Principal Underwriter and service
fees to the Principal  Underwriter and Authorized Firms which may be equivalent,
on an aggregate  basis  during any fiscal year of the Fund,  to 1% of the Fund's
average daily net assets for such year. For the sales commission and service fee
payments made by the Fund and the outstanding uncovered  distribution charges of
the Principal Underwriter,  see "Fees and Expenses -- Distribution Plan" in this
Part II. The Fund believes  that the combined rate of all these  payments may be
higher than the rate of payments made under  distribution plans adopted by other
investment companies pursuant to Rule 12b-1.  Although the Principal Underwriter
will  use  its own  funds  (which  may be  borrowed  from  banks)  to pay  sales
commissions  at the  time of  sale,  it is  anticipated  that  the  Eaton  Vance
organization  will  profit by reason of the  operation  of the Plan  through  an
increase in the Fund's assets  (thereby  increasing  the advisory fee payable to
BMR by the Portfolio) resulting from sale of Fund shares and through the amounts
paid to the Principal Underwriter,  including contingent deferred sales charges,
pursuant to the Plan.  The Eaton Vance  organization  may be  considered to have
realized a profit under the Plan if at any point in time the  aggregate  amounts
theretofore received by the Principal  Underwriter pursuant to the Plan and from
contingent  deferred sales charges have exceeded the total expenses  theretofore
incurred by such organization in distributing shares of the Fund. Total expenses
for this purpose will include an allocable portion of the overhead costs of such
organization and its branch offices, which costs will include without limitation
leasing   expense,   depreciation   of  building   and   equipment,   utilities,
communication  and postage  expense,  compensation  and  benefits of  personnel,
travel and promotional  expense,  stationery and supplies,  literature and sales
aids,  interest  expense,  data processing  fees,  consulting and temporary help
costs, insurance,  taxes other than income taxes, legal and auditing expense and
other  miscellaneous  overhead  items.  Overhead is calculated and allocated for
such purpose by the Eaton Vance organization in a manner deemed equitable to the
Fund.

    The  provisions  of the Plan relating to payments of sales  commissions  and
distribution  fees  to  the  Principal  Underwriter  are  also  included  in the
Distribution Agreement between the Trust on behalf of the Fund and the Principal
Underwriter.  Pursuant to Rule 12b-1,  the Plan has been  approved by the Fund's
initial sole shareholder (Eaton Vance) and by the Board of Trustees of the Trust
as required by Rule 12b-1.  The Plan  continues in effect  through and including
April 28, 1996, and shall continue in effect indefinitely thereafter for so long
as such continuance is approved at least annually by the vote of both a majority
of (i) the Trustees of the Trust who are not interested persons of the Trust and
who have no direct or indirect  financial  interest in the operation of the Plan
or any agreements  related to the Plan (the "Rule 12b-1  Trustees") and (ii) all
of the  Trustees  then in  office,  and the  Distribution  Agreement  contains a
similar provision.  The Plan and Distribution Agreement may be terminated at any
time by vote of a majority of the Rule 12b-1 Trustees or by a vote of a majority
of the outstanding  voting  securities of the Fund. Under the Plan the President
or a Vice President of the Trust shall provide to the Trustees for their review,
and the Trustees shall review at least quarterly, a written report of the amount
expended under the Plan and the purposes for which such  expenditures were made.
The Plan may not be  amended  to  increase  materially  the  payments  described
therein  without  approval of the  shareholders  of the Fund,  and all  material
amendments of the Plan must also be approved by the Trustees as required by Rule
12b-1.  So long as the  Plan is in  effect,  the  selection  and  nomination  of
Trustees who are not  interested  persons of the Trust shall be committed to the
discretion of the Trustees who are not such interested persons.
    

    The Trustees of the Trust believe that the Plan will be a significant factor
in the  expected  growth of the  Fund's  assets,  and will  result in  increased
investment  flexibility  and  advantages  which  will  benefit  the Fund and its
shareholders.  Payments for sales  commissions and distribution fees made to the
Principal  Underwriter under the Plan will compensate the Principal  Underwriter
for its services and expenses in  distributing  shares of the Fund.  Service fee
payments made to the Principal  Underwriter and Authorized  Firms under the Plan
provide incentives to provide continuing  personal services to investors and the
maintenance of shareholder  accounts.  By providing  incentives to the Principal
Underwriter  and  Authorized  Firms,  the  Plan is  expected  to  result  in the
maintenance of, and possible future growth in, the assets of the Fund.  Based on
the  foregoing  and other  relevant  factors,  the  Trustees  of the Trust  have
determined that in their judgment there is a reasonable likelihood that the Plan
will benefit the Fund and its shareholders.

                         NOTES TO FINANCIAL STATEMENTS
                                  (UNAUDITED)

- --------------------------------------------------------------------------------
(1) SIGNIFICANT ACCOUNTING POLICIES
EV Marathon Growth Fund (the Fund) is a diversified series of Eaton Vance Growth
Trust  (the  Trust).  The  Trust is an entity  of the type  commonly  known as a
Massachusetts  business trust and is registered under the Investment Company Act
of 1940, as amended,  as an open-end  management  investment  company.  The Fund
invests all of its investable  assets in interests in the Growth  Portfolio (the
Portfolio),  a New York Trust, having the same investment objective as the Fund.
The  value  of the  Fund's  investment  in the  Portfolio  reflects  the  Fund's
proportionate interest in the net assets of the Portfolio (0.55% at February 28,
1995).  The  performance of the Fund is directly  affected by the performance of
the  Portfolio.  The  financial  statements  of  the  Portfolio,  including  the
portfolio of  investments,  are included  elsewhere in this report and should be
read in conjunction  with the Fund's  financial  statements.  The following is a
summary of significant  accounting policies consistently followed by the Fund in
the preparation of its financial statements. The policies are in conformity with
generally accepted accounting principles.

A.  INVESTMENT  VALUATIONS  --  Valuations  of  securities  by the  Portfolio is
discussed in Note 1 of the Portfolio's  Notes to Financial  Statements which are
included elsewhere in this report.

B. INCOME -- The Fund's net  investment  income  consists of the Fund's pro rata
share of the net investment income of the Portfolio, less all actual and accrued
expenses of the Fund determined in accordance with generally accepted accounting
principles.

C. FEDERAL  TAXES -- The Fund's  policy is to comply with the  provisions of the
Internal  Revenue Code  applicable  to  regulated  investment  companies  and to
distribute to shareholders  each year all of its taxable  income,  including any
net realized gain on investments,  options and financial  futures  transactions.
Accordingly, no provision for federal income or excise tax is necessary.

D. DEFERRED  ORGANIZATION  EXPENSES -- Costs  incurred by the Fund in connection
with its organization,  are being amortized on the straight-line basis over five
years beginning on the date the Fund commenced operations.

E.  OTHER  --  Investment  transactions  are  accounted  for  on  the  date  the
investments are purchased or sold. Distributions to shareholders are recorded on
the ex-dividend date and interest income is recorded on the accrual basis.

F. DISTRIBUTION COSTS -- For book purposes, commissions paid on the sale of Fund
shares and other distribution costs are charged to operations. For tax purposes,
commissions  paid were charged to paid-in capital prior to November 16, 1994 and
subsequently  charged to operations.  The change in the tax accounting  practice
was prompted by a recent  Internal  Revenue  Service ruling and has no effect on
either the Fund's current yield or total return (Note 5).

G.  DISTRIBUTIONS  --  Generally  accepted  accounting  principles  require that
differences in the recognition or classification of income between the financial
statements   and  tax   earnings   and  profits   which   result  in   temporary
over-distributions   for  financial  statement   purposes,   are  classified  as
distributions  in excess of net investment  income or  accumulated  net realized
gains.

H. INTERIM FINANCIAL INFORMATION -- The interim financial statements relating to
February  28,  1995 and for the  period  then  ended  have not been  audited  by
independent  certified  public  accountants,  but in the  opinion  of the Fund's
management,  reflect  all  adjustments,  consisting  only  of  normal  recurring
adjustments, necessary for the fair presentation of the financial statements.

- --------------------------------------------------------------------------------
(2) SHARES OF BENEFICIAL INTEREST
The  Declaration  of Trust permits the Trustees to issue an unlimited  number of
full  and  fractional  shares  of  beneficial   interest  (without  par  value).
Transactions  in Fund shares from the start of  business  September  13, 1994 to
February 28, 1995 were as follows:


                             SHARES           AMOUNT

(3) INVESTMENT TRANSACTIONS
Increases  and decreases in the Fund's  investment  in the Portfolio  aggregated
$847,384 and $197,296 respectively.
- --------------------------------------------------------------------------------
(4) DISTRIBUTION PLAN
The Fund has adopted a  Distribution  Plan (the  "Plan")  pursuant to Rule 12b-1
under the Investment  Company Act of 1940. The Plan requires the Fund to pay the
principal  underwriter,  Eaton Vance Distributors,  Inc. (EVD), amounts equal to
1/365th  of  0.75%  of the  Fund's  daily  net  assets,  for  providing  ongoing
distribution  services and facilities to the Fund.  The Fund will  automatically
discontinue  payments to EVD during any period in which there are no outstanding
Uncovered Distribution Charges, which are equivalent to the sum of (i) 5% of the
aggregate  amount received by the Fund for shares sold plus,  (ii)  distribution
fees calculated by applying the rate of 1% over the prevailing prime rate to the
outstanding balance of Uncovered Distribution Charges of EVD, reduced by amounts
theretofore  paid to EVD. The amount  payable to EVD with respect to each day is
accrued on such day as a  liability  of the Fund and,  accordingly,  reduces the
Fund's net assets. The Fund paid $1,278 to EVD for the period ended February 28,
1995,  representing  0.75% (annualized) of average daily net assets. At February
28, 1995, the amount of Uncovered  Distribution  Charges of EVD calculated under
the Plan was approximately $27,052.

In addition,  the Plan  authorizes  the Fund to make payments of service fees to
the  Principal  Underwriter,  Authorized  Firms and other persons in amounts not
exceeding 0.25% of the Fund's average daily net assets for each fiscal year. The
Trustees have  implemented  the Plan by  authorizing  the Fund to make quarterly
payments of service fees to the Principal  Underwriter  and Authorized  Firms in
amounts not expected to exceed 0.25% of the Fund's  average daily net assets for
each  fiscal  year based on the value of Fund  shares  sold by such  persons and
remaining  outstanding  for at least twelve  months,  and that payments of these
service fees shall commence with the quarter ending  December 31, 1995.  Service
fees are separate and distinct from the sales  commissions and distribution fees
payable  by the  Fund  to EVD,  and,  as  such,  are not  subject  to  automatic
discontinuance when there are no outstanding  Uncovered  Distribution Charges of
EVD.

Certain officers and Trustees of the Fund are officers or directors of EVD.
- ------------------------------------------------------------------------------
(5) CONTINGENT DEFERRED SALES CHARGE
A contingent  deferred  sales charge (CDSC) is imposed on any redemption of Fund
shares made within six years of purchase.  Generally, the CDSC is based upon the
lower of the net  asset  value at date of  redemption  or date of  purchase.  No
charge is levied on shares acquired by reinvestment of dividends or capital gain
distributions.  The CDSC is imposed at  declining  rates that begin at 5% in the
first and second year of redemption  after  purchase,  declining one  percentage
point each subsequent  year. No CDSC is levied on shares which have been sold to
EVM or its affiliates or to their respective employees or clients.  CDSC charges
are  paid  to EVD  to  reduce  the  amount  of  Uncovered  Distribution  Charges
calculated  under the Fund's  Distribution  Plan. CDSC charges  received when no
Uncovered  Distribution Charges exist will be retained by the Fund. EVD received
approximately  $837 of CDSC paid by  shareholders  for the period ended February
28, 1995.

(6) TRANSACTIONS WITH AFFILIATES
Eaton Vance Management  (EVM) serves only as the  administrator of the Fund, but
receives no  compensation.  The  Portfolio  has engaged  Boston  Management  and
Research (BMR), a subsidiary of EVM, to render investment advisory services. See
Note 2 of the  Portfolio's  Notes to  Financial  Statements  which are  included
elsewhere  in this  report.  To enhance  the net  income of the Fund,  $6,234 of
expenses  related to the operation of the Fund were allocated,  on a preliminary
basis,  to EVM.  Except as to Trustees of the Fund and the Portfolio who are not
members  of  EVM's  or  BMR's  organizations,   officers  and  Trustees  receive
remuneration for their services to the Fund out of such investment  adviser fee.
Investors Bank & Trust Company (IBT),  an affiliate of EVM,  serves as custodian
of  the  Fund  and  the  Portfolio.   Pursuant  to  their  respective  custodian
agreements,  IBT receives a fee reduced by credits which are determined based on
the average  cash  balances  of the Fund or the  Portfolio  maintains  with IBT.
Certain of the officers and Trustees of the Fund and  Portfolio are officers and
directors/trustees of the above organizations.

                         NOTES TO FINANCIAL STATEMENTS
                               FEBRUARY 28, 1995
                                  (UNAUDITED)
- --------------------------------------------------------------------------------
(1) SIGNIFICANT ACCOUNTING POLICIES
Growth Portfolio (the Portfolio) is registered under the Investment  Company Act
of 1940 as a diversified  open-end  investment  company which was organized as a
trust under the laws of the State of New York on August 2, 1994. The Declaration
of Trust permits the Trustees to issue  interests in the  Portfolio.  Investment
operations  began on August 2, 1994, with the acquisition of investments  with a
value of  $127,122,709,  including  unrealized  appreciation  of  $6,444,330  in
exchange for an interest in the Portfolio by one of the  Portfolio's  investors.
The following is a summary of significant  accounting policies of the Portfolio.
The policies are in conformity with generally accepted accounting principles.

A. INVESTMENT VALUATIONS -- Investments listed on securities exchanges or in the
NASDAQ  National  Market are valued at closing sale  prices.  Listed or unlisted
investments  for which  closing sale prices are not  available are valued at the
mean between the latest bid and asked prices.  Short-term obligations are valued
at amortized cost, which approximates value. Foreign securities held by the Fund
are valued in U.S. dollars at the current exchange rate.

B. INCOME  TAXES -- The  Portfolio is treated as a  partnership  for federal tax
purposes.  No provision is made by the  Portfolio  for federal or state taxes on
any taxable  income of the  Portfolio  because each investor in the Portfolio is
ultimately  responsible  for  the  payment  of  any  taxes.  Since  some  of the
Portfolio's  investors are  regulated  investment  companies  that invest all or
substantially all of their assets in the Portfolio,  the Portfolio normally must
satisfy the applicable source of income and diversification  requirements (under
the  Internal  Revenue  Code) in order for its  investors to satisfy  them.  The
Portfolio will allocate at least  annually  among its investors each  investors'
distributive  share of the  Portfolio's  net  taxable  (if  any) and  tax-exempt
investment  income,  net realized  capital gains, and any other items of income,
gain,  loss,  deduction or credit.  Interest income received by the Portfolio on
investments in municipal bonds,  which is excludable from gross income under the
Internal  Revenue  Code,  will retain its status as income  exempt from  Federal
income tax when  allocated  to the  Portfolio's  investors.  The portion of such
interest,  if any, earned on private  activity bonds issued after August 7, 1986
may be considered a tax preference item for investors.

C.  DEFERRED  ORGANIZATION  EXPENSES  --  Costs  incurred  by the  Portfolio  in
connection with its organization are being amortized on the straight-line  basis
over five years.

D. LEGAL  FEES -- Legal  fees and other  related  expenses  incurred  as part of
negotiations  of the terms and  requirements of capital  infusions,  or that are
expected to result in the  restructuring of or a plan of  reorganization  for an
investment are added to the cost of the investment.

E.  OTHER  --  Investment  transactions  are  accounted  for  on  the  date  the
investments  are  purchased  or  sold.  Dividend  income  and  distributions  to
shareholders  are  recorded  on the  ex-dividend  date and  interest  income  is
recorded on the accrual basis. 

- --------------------------------------------------------------------------------
(2) INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES
The investment  adviser fee is earned by Boston Management and Research (BMR), a
wholly-owned  subsidiary of Eaton Vance  Management  (EVM), as compensation  for
management and investment  advisory services rendered to the Portfolio.  The fee
is based upon a percentage of average daily net assets. For the six months ended
February  28,  1995,  the fee  was  equivalent  to  0.625%  (annualized)  of the
Portfolio's average net assets for such period and amounted to $384,275.  Except
as to  Trustees  of the  Portfolio  who  are  not  members  of  EVM's  or  BMR's
organization,  officers and Trustees receive  remuneration for their services to
the Fund out of such  investment  adviser fee.  Investors  Bank & Trust  Company
(IBT), an affiliate of EVM and BMR, serves as custodian of the Fund. Pursuant to
the  custodian  agreement,  IBT  receives a fee  reduced  by  credits  which are
determined based on the average daily cash balances the Portfolio maintains with
IBT.  Certain of the  officers and  Trustees of the  Portfolio  are officers and
directors/trustees of the above organizations.

- --------------------------------------------------------------------------------
(3) PURCHASES AND SALES OF INVESTMENTS
Purchases  and  sales  of  investments,   other  than  short  term  obligations,
aggregated $36,944,589 and $39,114,037, respectively.

- --------------------------------------------------------------------------------
(4)  FEDERAL   INCOME  TAX  BASIS  OF   INVESTMENTS
The cost and unrealized  appreciation/depreciation  in value of the  investments
owned at February 28, 1995,  as computed on a federal  income tax basis,  are as
follows:

Aggregate cost                                          $111,249,615 
                                                        ============
Gross unrealized appreciation                           $ 15,198,431
Gross unrealized depreciation                             (3,774,144)
                                                        ------------
   Net unrealized appreciation                          $ 11,424,287
                                                        ============

- --------------------------------------------------------------------------------
(5) LINE OF CREDIT
The Portfolio  participates  with other  portfolios and funds managed by BMR and
EVM and its affiliates in a $120 million unsecured line of credit agreement with
a bank. The line of credit consists of $20 million committed facility and a $100
million discretionary facility.  Borrowings will be made by the Portfolio solely
to  facilitate  the handling of unusual  and/or  unanticipated  short-term  cash
requirements.  Interest is charged to each portfolio  based on its borrowings at
an amount  above  either the bank's  adjusted  certificate  of deposit  rate,  a
variable  adjusted  certificate  of deposit rate,  or a federal funds  effective
rate.  In  addition,  a fee  computed  at an annual rate of 1/4 of 1% on the $20
million  committed  facility and on the daily unused portion of the $100 million
discretionary facility is allocated among the participating funds and portfolios
at the  end of  each  quarter.  The  Portfolio  did  not  have  any  significant
borrowings or allocated  fees during the period.  At February 28, 1995, the Fund
did not have an outstanding balance pursuant to the line of credit.
