FUND SUMMARY


Investment Objective and Principal  Strategies.  The Fund's investment objective
is to  provide  a high  level of  current  income.  To do so,  the Fund  invests
primarily in high yield, high risk corporate bonds (so-called "junk bonds"). The
Fund will invest a  substantial  portion of assets in bonds issued in connection
with mergers, acquisitions and other highly- leveraged transactions.

The Fund  invests  at least 80% of its net  assets in  fixed-income  securities,
including preferred stocks (many of which have fixed maturities) and convertible
securities.  The Fund may also purchase  securities that make "in-kind" interest
payments,  bonds not paying  current  income and bonds that do not make  regular
interest payments.  The Fund may invest up to 25% of its total assets in foreign
securities  and may hedge  currency  fluctuations  by entering  forward  foreign
currency exchange contracts.  The Fund will generally hold well in excess of 100
securities, which helps reduce investment risk.

Investments  are actively  managed,  and  securities  may be bought or sold on a
daily basis.  The  investment  adviser's  staff  monitors the credit quality and
price of  securities  held by the  Fund,  as well as other  securities  that are
available to the Fund. The portfolio  manager  attempts to improve yield through
timely  trading.  The portfolio  manager also  considers  the relative  value of
securities in the marketplace in making  investment  decisions,  and attempts to
preserve capital and enhance return when consistent with the Fund's objective.


The  Fund   currently   invests  its  assets  in  High  Income   Portfolio  (the
"Portfolio"),  a separate registered investment company with the same investment
objective and policies as the Fund.


Principal Risk Factors.  The Fund invests  primarily in below  investment  grade
bonds, which are predominantly  speculative  because of the credit risk of their
issuers. Such companies are more likely to default on their payments of interest
and  principal  owed to the Fund,  and such  defaults will reduce the Fund's net
asset value and income distributions.  An economic downturn generally leads to a
higher  non-payment  rate,  and a security may lose  significant  value before a
default occurs.

The value of Fund shares may also decline  when  interest  rates rise,  when the
supply of suitable bonds exceeds market demand,  or in response to a significant
drop in the stock market.  Bonds that do not make regular interest  payments may
experience greater volatility in response to interest rate changes.  Because the
Fund  invests a portion of its assets in foreign  securities,  the value of Fund
shares could be adversely  affected by changes in currency exchange rates and by
political and economic  developments  abroad.  Forward foreign currency exchange
contracts also involve a risk of loss due to  unanticipated  changes in exchange
rates, as well as the risk of counterparty  default. The Fund is not appropriate
for investors who cannot assume the greater risk of capital depreciation or loss
inherent in seeking higher yields.


The  Fund  is not a  complete  investment  program  and you may  lose  money  by
investing in the Fund.  An investment in the Fund is not a deposit in a bank and
is not insured or guaranteed by the Federal Deposit Insurance Corporation or any
other government agency.

Performance  Information.  The following bar chart and table provide information
about the Fund's  performance,  including a comparison of the Fund's performance
to the  performance  of a  broad-based,  unmanaged  market  index of high  yield
corporate  bonds.  Although past  performance is no guarantee of future results,
this  performance  information  demonstrates  the risk  that  the  value of your
investment  will change.  The following  returns are for Class B shares for each
calendar year through  December 31, 1998 and do not reflect a sales  charge.  If
the sales charge was reflected, the returns would be lower.

1.13%  -18.45%  38.34%  17.79%  16.92%  -1.81%  13.86%  13.78%  15.35%  1.77%

The Fund's highest  quarterly total return was 11.37% for the quarter ended June
30, 1991, and its lowest quarterly total return was -9.19% for the quarter ended
September 30, 1990.  The  year-to-date  total return through the end of the most
recent calendar quarter  (December 31, 1998 to June 30, 1999) was 6.83%. For the
30 days ended March 31, 1999, the SEC yield for Class B shares was 8.92% and for
Class C shares was 8.89%. For current yield information call 1-800-225-6265.

These returns  reflect any applicable  CDSC for Class B and Class C. The Class C
performance  shown above for the period prior to June 8, 1994 is the performance
of Class B shares,  adjusted for the sales charge that applies to Class C shares
(but not adjusted for any other differences in the expenses of the classes). The
C. S. First  Boston  High Yield Bond Index is a  broad-based,  unmanaged  market
index of high yield  corporate  bonds.  Investors  cannot invest  directly in an
index.  (Source for C.S. First Boston High Yield Bond Index returns:  C.S. First

Example.  This  Example is intended to help you compare the cost of investing in
the Fund with the cost of investing in other mutual funds.  The Example  assumes
that you invest  $10,000  in the Fund for the time  periods  indicated  and then
redeem all of your shares at the end of those periods.  The Example also assumes
that your  investment has a 5% return each year and that the operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your costs would be:

                                       1 Year    3 Years    5 Years    10 Years
- --------------------------------------------------------------------------------
Class B shares                         $678      $951       $1,149     $2,062
Class C shares                         $282      $563       $  970     $2,105

You would pay the following expenses if you did not redeem your shares:

                                       1 Year    3 Years    5 Years    10 Years

INVESTMENT OBJECTIVE & PRINCIPAL POLICIES AND RISKS


The Fund's  investment  objective is to provide a high level of current  income.
The Fund's  investment  objective  and  certain  policies  may be changed by the
Trustees without shareholder approval. The Trustees have no present intention to
make a change and  intend to submit  any  material  change in the  objective  to
shareholders  for  approval.  The Fund  currently  seeks to meet its  investment
objective by investing in High Income  Portfolio (the  "Portfolio"),  a separate
open-ended  management  company that has the same  objective and policies as the
Fund.

The Portfolio  normally  invests at least 65% of its total assets in bonds rated
in the lowest investment grade category or below (i.e. bonds rated Baa and below
by Moody's Investors  Service,  Inc.  ("Moody's") or BBB and below by Standard &
Poor's Ratings Group ("S&P")),  and in comparable unrated bonds. Bonds rated Baa
and  BBB  have  speculative   characteristics,   while  lower  rated  bonds  are
predominantly speculative.

The  Portfolio  may hold  securities  that are  unrated or in the lowest  rating
categories  (rated C by  Moody's  or D by S&P).  Bonds  rated C by  Moody's  are
regarded  as  having  extremely  poor  prospects  of  ever  attaining  any  real
investment standing. Bonds rated D by S&P are in payment default or a bankruptcy
petition has been filed and debt service payments are  jeopardized.  In order to
enforce its rights with defaulted  securities,  the Portfolio may be required to
retain  legal  counsel  and/or  a  financial  adviser.  This  may  increase  the
Portfolio's operating expenses and adversely affect the Fund's net asset value.

The credit quality of most securities  held by the Portfolio  reflects a greater
possibility that adverse changes in the financial  condition of an issuer, or in
general  economic  conditions,  or both, may impair the ability of the issuer to
make payments of interest and principal.  The inability (or perceived inability)
of issuers to make timely  payment of interest and  principal  would likely make
the values of securities held by the Portfolio more volatile and could limit the
Portfolio's  ability to sell its securities at favorable  prices. In the absence
of a liquid  trading  market for  securities  held by it, the Portfolio may have
difficulties determining the fair market value of such securities.


Although  the  investment   adviser  considers   security  ratings  when  making
investment  decisions,  it performs its own credit and  investment  analysis and
does not rely  primarily  on the  ratings  assigned by the rating  services.  In
evaluating  the quality of a particular  issue,  whether  rated or unrated,  the
investment  adviser will normally take into  consideration,  among other things,
the issuer's  financial  resources and operating  history,  its  sensitivity  to
economic conditions and trends, the ability of its management, its debt maturity
schedules and borrowing  requirements,  and relative values based on anticipated
cash flow, interest and asset coverage,  and earnings prospects.  Because of the
greater number of investment considerations involved in investing in high yield,
high risk bonds,  the achievement of the Fund's  objectives  depends more on the
investment adviser's judgment and analytical abilities than would be the case if
the Portfolio  invested primarily in securities in the higher rating categories.
While the  investment  adviser  will attempt to reduce the risks of investing in
lower  rated  or  unrated  securities   through  active  portfolio   management,
diversification,  credit  analysis  and  attention to current  developments  and
trends in the economy and the financial markets,  there can be no assurance that
a broadly diversified  portfolio of such securities would  substantially  lessen
the risks of defaults brought about by an economic downturn or recession.


The Portfolio may invest in zero coupon bonds, deferred interest bonds and bonds
or preferred stocks on which the interest is payable in-kind ("PIK bonds"). Zero
coupon and deferred  interest bonds are debt  obligations  which are issued at a
significant discount from face value. While zero coupon bonds do not require the
periodic  payment of interest,  deferred  interest bonds provide for a period of
delay  before  the  regular  payment  of  interest  begins.  PIK  bonds are debt
obligations  which  provide  that the issuer  thereof  may, at its  option,  pay
interest on such bonds in cash or in the form of  additional  debt  obligations.
Such  investments  may  experience  greater  volatility  in market  value due to
changes in interest rates. The Portfolio accrues income on these investments and
the Fund is required to distribute its share of Portfolio  income each year. The
Portfolio  may be required to sell  securities  to obtain cash needed for income
distributions.

The  Portfolio may invest up to 25% of total assets in foreign  securities.  The
value of foreign  securities is affected by changes in currency  rates,  foreign
tax laws (including  withholding tax),  government  policies (in this country or
abroad) and  relations  between  nations.  In  addition,  the costs of investing
abroad are generally  higher than in the United States,  and foreign  securities
markets may be less  liquid,  more  volatile  and less  subject to  governmental
supervision  than markets in the United  States.  The portfolio  manager may use
forward  currency  exchange  contracts to attempt to mitigate adverse effects of
foreign currency fluctuations.  These contracts allow the Portfolio to establish
a currency  exchange  rate with payment and delivery at a future date.  They are
subject  to a risk of loss due to  unanticipated  changes in  currency  exchange
rates and default by the counterparty to the contract. There can be no assurance
that this hedging strategy will be advantageous to the Portfolio.

                                        4
<PAGE>
The value of Fund shares  will  usually  change in  response  to  interest  rate
fluctuations.  When interest rates decline, the value of securities already held
by the Portfolio can be expected to rise. Conversely,  when interest rates rise,
the value of existing  portfolio  securities  can be expected to decline.  Other
economic  factors (such as a large  downward  movement in stock prices) can also
adversely  impact the high yield bond market.  Rating  downgrades  of securities
held by the Portfolio may reduce their value.


The  Portfolio may borrow  amounts up to 25% of its net assets,  but it will not
borrow  more  than  5% of the  value  of its  total  assets  except  to  satisfy
redemption  requests or for other  temporary  purposes.  Such  borrowings  would
result in increased  expense to the Fund and, while they are outstanding,  would
magnify  increases or decreases in the value of Fund shares.  The Portfolio will
not purchase additional portfolio securities while outstanding borrowings exceed
5% of the value of its total assets.


The annual  portfolio  turnover  rate may exceed 100%. A mutual fund with a high
turnover  rate (100% or more) may generate more capital gains than a fund with a
lower  rate.  Capital  gains  distributions  will  be made  to  shareholders  if
offsetting  capital  loss  carryforwards  do not exist,  which  reduce after tax
returns of shareholders holding Fund shares in taxable accounts.

Like most mutual funds,  the Fund and Portfolio  rely on computers in conducting
daily business and processing information. There is a concern that on January 1,
2000 some  computer  programs  will be unable to recognize the new year and as a
consequence  computer  malfunctions will occur. Eaton Vance is taking steps that
it believes are  reasonably  designed to address this  potential  problem and to
obtain  satisfactory  assurance from other service providers to the Fund and the
Portfolio  that they are also  taking  steps to address  the  issue.  There can,
however,  be no  assurance  that  these  steps will be  sufficient  to avoid any
adverse  impact on the Fund and the  Portfolio  or  shareholders.  The Year 2000
concern may also adversely  impact issuers of obligations  held by the Portfolio
and the markets in which these  securities  trade.  The  foregoing  statement is
subject to the Year 2000  Information  and Readiness  Disclosure  Act, which may
protect Eaton Vance and the Fund and the Portfolio from  liability  arising from
the statement.

1996).  He  also  manages  other  Eaton  Vance  portfolios.  Prior  to  assuming
management of the  Portfolio,  Mr.  Weilheimer was a senior analyst in the Eaton
Vance high yield bond group. He is a Vice President of Eaton Vance and BMR.

The  investment  adviser and the Fund and the  Portfolio  have adopted  Codes of
Ethics governing personal securities transactions. Under the Codes, employees of
Eaton Vance may purchase and sell securities  (including  securities held by the
Fund)  subject to certain  pre-clearance  and reporting  requirements  and other
procedures.

Eaton  Vance  serves  as  administrator  of the  Fund,  providing  the Fund with
administrative  services  and related  office  facilities.  Eaton Vance does not
currently receive a fee for serving as administrator.

Organization.  The Fund is a  series  of  Eaton  Vance  Mutual  Funds  Trust,  a
Massachusetts  business trust. The Fund offers multiple classes of shares.  Each
class  represents a pro rata  interest in the Fund,  but is subject to different
expenses and rights. The Fund does not hold annual shareholder meetings, but may
hold  special  meetings  for matters that  require  shareholder  approval  (like
electing  or  removing  trustees,  approving  management  contracts  or changing
investment policies that may only be changed with shareholder approval). Because
the Fund invests in the Portfolio,  it may be asked to vote on certain Portfolio
matters  (like  changes  in certain  Portfolio  investment  restrictions).  When
necessary,  the Fund will hold a meeting of its  shareholders  to  consider  the
Portfolio  matter and then vote its interest in the  Portfolio in  proportion to
the votes cast by its shareholders.  The Fund can withdraw from the Portfolio at
any time.

VALUING SHARES

The Fund values its shares  once each day only when the New York Stock  Exchange
is open for  trading  (typically  Monday  through  Friday),  as of the  close of
regular trading on the Exchange  (normally 4:00 p.m. eastern time). The price of
Fund shares is their net asset value, which is derived from Portfolio  holdings.
Most debt securities are valued by an independent pricing service.

When  purchasing  or  redeeming  Fund  shares,   your  investment   dealer  must
communicate your order to the principal  underwriter by a specific time each day
in order for the purchase  price or  redemption  price to be based on that day's
net asset  value per share.  It is the  investment  dealer's  responsibility  to
transmit orders promptly.  The Fund may accept purchase and redemption orders as
of the time of their receipt by certain  investment dealers (or their designated
intermediaries).

PURCHASING SHARES

You may purchase Fund shares  through your  investment  dealer or by mailing the
account  application form included in this prospectus to the transfer agent (see
back cover for address).  Your initial  investment must be at least $1,000.  The
price of Class B and Class C shares is the net asset value;  however, you may be
subject  to a sales  charge  (called a  "contingent  deferred  sales  charge" or
"CDSC") if you redeem  Class B shares  within six years of  purchase  or Class C
shares within one year of purchase.  The sales charges are described below. Your
investment  dealer  can  help  you  decide  which  class of  shares  suits  your
investment needs.

After your initial investment, additional investments of $50 or more may be made
at any time by sending a check  payable to the order of the Fund or the transfer
agent  directly  to the  transfer  agent  (see back cover for  address).  Please
include  your name and  account  number  and the name of the Fund and Class with
each investment.

You may  also  make  automatic  investments  of $50 or more  each  month or each
quarter from your bank account.  You can establish bank  automated  investing on
the  account  application  or by calling  1-800-262-1122.  The  minimum  initial
investment  amount  and Fund  policy  of  redeeming  accounts  with low  account
balances are waived for bank  automated  investing  accounts  and certain  group
purchase plans.

SALES CHARGES

Contingent  Deferred Sales Charge.  Each class of shares is subject to a CDSC on
certain  redemptions.  Class C shares are  subject  to a 1.00% CDSC if  redeemed
within 12 months of purchase.  Class B shares are subject to the following  CDSC
schedule:

Year of Redemption After Purchase                                          CDSC
- --------------------------------------------------------------------------------
First or Second                                                            5%
Third                                                                      4%
Fourth                                                                     3%
Fifth                                                                      2%
Sixth                                                                      1%
Seventh or following                                                       0%

The CDSC is based on the lower of the net asset value at the time of purchase or
the  time  of  redemption.   Shares   acquired   through  the   reinvestment  of
distributions  are exempt from the CDSC.  Redemptions are made first from shares
that are not subject to a CDSC.

                                        6
<PAGE>

The principal  underwriter  pays  commissions to investment  dealers on sales of
Class B and Class C shares (except exchange transactions and reinvestments). The
sales  commission  on  Class B shares  equals  4% of the  purchase  price of the
shares.  The sales  commission  on Class C shares  equals  0.75% of the purchase
price of the shares. After the first year, investment dealers also receive 0.75%
of the value of Class C shares in distribution fees.

CDSCs are waived for  certain  redemptions  pursuant to a  Withdrawal  Plan (see
"Shareholder  Account Features") and in connection with certain redemptions from
tax-sheltered  retirement plans. Call  1-800-225-6265  for details.  The Class B
CDSC is also waived following the death of all beneficial owners of shares,  but
only if the  redemption  is  requested  within  one  year  after  death (a death
certificate and other applicable documents may be required).


If you redeem shares,  you may reinvest at net asset value any portion or all of
the  redemption  proceeds in the same class of shares of the Fund  provided that
the reinvestment occurs within 60 days of the redemption,  and the privilege has
not been  used  more than once in the  prior 12  months.  Your  account  will be
credited  with any CDSC paid in  connection  with the  redemption.  Reinvestment
requests  must be in writing.  If you  reinvest,  you will be sold shares at the
next determined net asset value following receipt of your request.

Distribution  and Service  Fees.  Class B and Class C shares have adopted a plan
under Rule 12b-1 that allows the Fund to pay distribution  fees for the sale and
distribution of shares (so-called "12b-1 fees").  Class B and Class C shares pay
distribution  fees of 0.75% of average daily net assets annually.  Because these
fees are paid from Fund assets on an ongoing basis, they will increase your cost
over time and may cost you more than paying other types of sales charges.  Class
B and  Class C pay  service  fees  for  personal  and/or  account  services  not
exceeding  0.25% of average daily net assets  annually.  Class B shares only pay
service fees on shares that have been outstanding for 12 months.

REDEEMING SHARES

You can redeem shares in any of the following ways:

  By Mail               Send your request to the transfer agent along with any
                        certificates and stock powers. The request must be
                        signed exactly as your account is registered and
                        signature guaranteed.  You can obtain a signature
                        guarantee at certain banks, savings and loan
                        institutions, credit unions, securities dealers,
                        securities exchanges, clearing agencies and registered
                        securities associations.  You may be asked to provide
                        additional documents if your shares are registered in
                        the name of a corporation, partnership or fiduciary.

  By Telephone          You can redeem up to $50,000 by calling the transfer
                        agent at 1-800-262-1122 on Monday through Friday, 9:00
                        a.m. to 4:00 p.m. (eastern time). Proceeds of a
                        telephone redemption can be mailed only to the account
                        address.  Shares held by corporations, trusts or certain
                        other entities, or subject to fiduciary arrangements,
                        cannot be redeemed by telephone.

  Through an
  Investment
  Dealer                Your investment dealer is responsible for transmitting
                        the order promptly.  A dealer may charge a fee for this
                        service.

If you redeem shares, your redemption price will be based on the net asset value
per  share  next  computed  after  the  redemption  request  is  received.  Your
redemption  proceeds  will be paid in cash  within  seven  days,  reduced by the
amount  of any  applicable  CDSC  and any  federal  income  tax  required  to be
withheld.  Payments  will be sent by mail  unless  you  complete  the Bank  Wire
Redemptions section of the account application.

If you recently  purchased shares, the proceeds of a redemption will not be sent
until the purchase check (including a certified or cashier's check) has cleared.
If the purchase check has not cleared,  redemption proceeds may be delayed up to
15 days from the purchase  date.  If your account  value falls below $750 (other
than due to market  decline),  you may be asked to either add to your account or
redeem it within 60 days.  If you take no action,  your account will be redeemed
and the proceeds sent to you.

While redemption proceeds are normally paid in cash,  redemptions may be paid by
distributing marketable securities.  If you receive securities,  you could incur
brokerage or other charges in converting the securities to cash.

SHAREHOLDER ACCOUNT FEATURES

Once you purchase shares,  the transfer agent  establishes a Lifetime  Investing
Account(R) for you. Share certificates are issued only on request.

Distributions. You may have your Fund distributions paid in one of the following
ways:

     * Full
       Reinvest
       Option       Dividends  and capital  gains are  reinvested  in additional
                    shares.  This  option will be assigned if you do not specify
                    an option.

     * Partial
       Reinvest
       Option       Dividends are paid in cash and capital gains are  reinvested
                    in  additional  shares.

     * Cash Option  Dividends  and  capital  gains  are paid in cash.

     * Exchange
       Option       Dividends  and/or capital gains are reinvested in additional
                    shares of another  Eaton  Vance fund  chosen by you.  Before
                    selecting  this option,  you must obtain a prospectus of the
                    other  fund  and  consider  its   objectives   and  policies
                    carefully.

Information from the Fund. From time to time, you may be mailed the following:

     *    Annual and Semi-Annual Reports, containing performance information and
          financial statements.
     *    Periodic account  statements,  showing recent activity and total share
          balance.
     *    Form  1099 and tax  information  needed to  prepare  your  income  tax
          returns.
     *    Proxy materials, in the event a shareholder vote is required.
     *    Special notices about significant events affecting your Fund.

Withdrawal  Plan. You may redeem shares on a regular  monthly or quarterly basis
by establishing a systematic withdrawal plan. Withdrawals will not be subject to
any applicable  CDSC if they do not in the aggregate  exceed 12% annually of the
account balance at the time the plan is  established.  A minimum account size of
$5,000 is required to establish a systematic withdrawal plan.


Tax-Sheltered  Retirement  Plans.  Class C shares are  available for purchase in
connection with certain tax-sheltered  retirement plans. Call 1-800-225-6265 for
information.  Distributions  will  be  invested  in  additional  shares  for all
tax-sheltered retirement plans.


Exchange Privilege.  You may exchange your Class B and Class C shares for shares
of the same class of another Eaton Vance fund.  Exchanges are generally  made at
net asset value. If your shares are subject to a CDSC, the CDSC will continue to
apply to your new shares at the same CDSC rate.  For purposes of the CDSC,  your
shares will continue to age from the date of your original purchase.

Before exchanging,  you should read the prospectus of the new fund carefully. If
you wish to exchange  shares,  you may write to the transfer  agent  (address on
back  cover)  or call  1-800-262-1122.  Periodic  automatic  exchanges  are also
available.  The exchange  privilege may be changed or  discontinued at any time.
You will receive 60 days' notice of any material  change to the privilege.  This
privilege  may not be used for  "market  timing".  If an  account  (or  group of
accounts) makes more than two round-trip  exchanges within 12 months, it will be
deemed to be market timing.  The exchange privilege may be terminated for market
timing accounts.

Telephone  Transactions.  You can  redeem or  exchange  shares by  telephone  as
described in this prospectus.  The transfer agent and the principal  underwriter
have  procedures  in  place  to  authenticate  telephone  instructions  (such as
verifying  personal  account  information).  As long as the  transfer  agent and
principal underwriter follow these procedures,  they will not be responsible for
unauthorized  telephone  transactions  and you bear the  risk of  possible  loss
resulting from telephone transactions.  You may decline the telephone redemption
option on the account application. Telephone instructions are tape recorded.

"Street Name" Accounts. If your shares are held in a "street name" account at an
investment  dealer,  that dealer (and not the Fund or its  transfer  agent) will
perform all  recordkeeping,  transaction  processing and distribution  payments.
Because the Fund will have no record of your  transactions,  you should  contact
your investment  dealer to purchase,  redeem or exchange shares, to make changes
in your account, or to obtain account  information.  The transfer of shares in a
"street  name"  account to an account  with another  investment  dealer or to an
account  directly  with the Fund  involves  special  procedures  and you will be
required  to  obtain  historical  information  about  your  shares  prior to the
transfer. Before establishing a "street name" account with an investment dealer,
you should determine whether that dealer allows reinvestment of distributions in
"street name" accounts.

Account Questions.  If you have any questions about your account or the services
available,  please call Eaton Vance Shareholder  Services at 1-800-225-6265,  or
write to the transfer agent (see back cover for address).

TAX INFORMATION

The Fund declares dividends daily and ordinarily pays distributions monthly. Any
net realized capital gains will be distributed once annually.  Your account will
be credited with dividends  beginning on the business day after the day when the
funds  used to  purchase  your  shares  are  collected  by the  transfer  agent.
Distributions will generally be taxable to shareholders as ordinary income.


Distributions  of any long-term  capital gains are taxable as long-term gains. A
portion  of  the  Fund's   distributions  may  be  eligible  for  the  corporate
dividends-received  deduction. The Fund's distributions are taxable as described
above  whether  they are paid in cash or  reinvested  in  additional  shares.  A
redemption of Fund shares,  including an exchange for shares of another fund, is
a taxable transaction.


Shareholders  should consult with their advisers concerning the applicability of
state, local and other taxes to an investment.

FINANCIAL HIGHLIGHTS

The  financial  highlights  are  intended  to help  you  understand  the  Fund's
financial  performance for the past five years. Certain information in the table
reflects the financial results for a single Fund share. The total returns in the
table  represent  the  rate an  investor  would  have  earned  (or  lost)  on an
investment  in the Fund  (assuming  reinvestment  of all  distributions  and not
taking  into  account a sales  charge).  This  information  has been  audited by
Deloitte & Touche LLP, independent accountants.  The report of Deloitte & Touche
LLP and the Fund's financial statements are incorporated herein by reference and
included in the annual  report,  which is available  on request.  The Fund began
offering  two classes of shares on April 1, 1998.  Prior to that date,  the Fund
offered only Class B shares and Class C existed as separate a fund.

                             STRATEGIES AND RISKS

    The rating assigned to a security by a rating agency does not reflect
assessment of the volatility of the security's market value or of the
liquidity of an investment in the securities. Credit ratings are based largely
on the issuer's historical financial condition and the rating agency's
investment analysis at the time of rating, and the rating assigned to any
particular security is not necessarily a reflection of the issuer's current
financial condition. Credit quality in the high yield high risk bond market
can change from time to time, and recently issued credit ratings may not fully
reflect the actual risks posed by a particular high yield security.

    Certain securities held by the Portfolio may permit the issuer at its
option to "call," or redeem, its securities. If an issuer were to redeem
securities held by the Portfolio during a time of declining interest rates,
the Portfolio may not be able to reinvest the proceeds in securities providing
the same investment return as the securities redeemed.


OTHER FIXED-INCOME SECURITIES. Included in the fixed-income securities in which
the Portfolio may invest are preferred, preference and convertible stocks,
equipment lease certificates, equipment trust certificates. Equipment lease
certificates are debt obligations secured by leases on equipment (such as
railroad cars, airplanes or office equipment), with the issuer of the
certificate being the owner and lessor of the equipment. Equipment trust
certificates are debt obligations secured by an interest in property (such as
railroad cars or airplanes), the title of which is held by a trustee while the
property is being used by the borrower.

    In addition to lower rated bonds, the Portfolio may invest in higher rated
securities. The Portfolio may also invest up to 20% of its net assets in
common stocks and other equity securities when consistent with its objective
or acquired as part of a fixed-income security. Equity securities are
sensitive to stock market volatility. Changes in stock market values can be
sudden and unpredictable. Even if values rebound, there is no assurance they
will return to previous levels.

LOAN INTERESTS. A loan in which the Portfolio may acquire a loan interest (a
"Loan Interest") is typically originated, negotiated and structured by a U.S.
or foreign commercial bank, insurance company, finance company or other
financial institution (the "Agent") for a lending syndicate of financial
institutions. The Agent typically administers and enforces the loan on behalf
of the other lenders in the syndicate. In addition, an institution, typically
but not always the Agent (the "Collateral Bank"), holds collateral (if any) on
behalf of the lenders. These Loan Interests may take the form of participation
interests in, assignments of or novations of a loan during its secondary
distribution, or direct interests during a primary distribution. Such Loan
Interests may be acquired from U.S. or foreign banks, insurance companies,
finance companies or other financial institutions who have made loans or are
members of a lending syndicate or from other holders of Loan Interests.


    The Portfolio may also acquire Loan Interests under which the Portfolio
derives its rights directly from the borrower. Such Loan Interests are
separately enforceable by the Portfolio against the borrower and all payments
of interest and principal are typically made directly to the Portfolio from
the borrower. In the event that the Portfolio and other lenders become
entitled to take possession of shared collateral, it is anticipated that such
collateral would be held in the custody of a Collateral Bank for their mutual
benefit. The Portfolio may not act as an Agent, a Collateral Bank, a guarantor
or sole negotiator or structurer with respect to a loan.

    The investment adviser will analyze and evaluate the financial condition
of the borrower in connection with the acquisition of any Loan Interest. The
investment adviser also analyzes and evaluates the financial condition of the
Agent and, in the case of Loan Interests in which the Portfolio does not have
privity with the borrower, those institutions from or through whom the
Portfolio derives its rights in a loan (the "Intermediate Participants"). From
time to time the investment adviser and its affiliates may borrow money from
various banks in connection with their business activities. Such banks may
also sell interests in loans to or acquire such interests from the Portfolio
or may be Intermediate Participants with respect to loans in which the
Portfolio owns interests. Such banks may also act as Agents for loans in which
the Portfolio owns interests.

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

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

    Purchasers of Loan interests depend primarily upon the creditworthiness of
the borrower for payment of principal and interest. If the Portfolio does not
receive scheduled interest or principal payments on such indebtedness, the
Portfolio could be adversely affected. Loans that are fully secured offer the
Portfolio more protections than an unsecured loan in the event of non-payment
of scheduled interest or principal. However, there is no assurance that the
liquidation of collateral from a secured loan would satisfy the borrower's
obligation, or that the collateral can be liquidated. Indebtedness of
borrowers whose creditworthiness is poor involves substantially greater risks,
and may be highly speculative. Borrowers that are in bankruptcy or
restructuring may never pay off their indebtedness, or may pay only a small
fraction of the amount owed. Direct indebtedness of developing countries will
also involve a risk that the governmental entities responsible for the
repayment of the debt may be unable, or unwilling, to pay interest and repay
principal when due.

    The Portfolio limits the amount of total assets that it will invest in any
one issuer or in issuers within the same industry. See Investment Restrictions
(1) and (5) below. For purposes of these restrictions, the Portfolio generally
will treat the borrower as the "issuer" of a Loan Interest held by the
Portfolio. In the case of loan participations where the Agent or Intermediate
Participant serves as financial intermediary between the Portfolio and the
borrower, the Portfolio, in appropriate circumstances, will treat both the
Agent or Intermediate Participant and the borrower as "issuers" for the
purposes of determining whether the Portfolio has invested more than 5% of its
total assets in a single issuer. Treating a financial intermediary as an
issuer of indebtedness may restrict the Portfolio's ability to invest in
indebtedness related to a single intermediary, or a group of intermediaries
engaged in the same industry, even if the underlying borrowers represent many
different companies and industries.

FOREIGN INVESTMENTS. Investing in foreign issuers involves certain special
considerations, including those set forth below, which are not typically
associated with investing in U.S. issuers. Since investments in foreign
issuers may involve currencies of foreign countries, and since the Portfolio
may temporarily hold funds in bank deposits in foreign currencies during
completion of investment programs, the Portfolio may be affected favorably or
unfavorably by changes in currency rates and in exchange control regulations
and may incur costs in connection with conversions between various currencies.

    Since foreign companies are not subject to uniform accounting, auditing
and financial reporting standards, practices and requirements comparable to
those applicable to U.S. companies, there may be less publicly available
information about a foreign company than about a domestic company. Foreign
stock markets, while growing in volume of trading activity, have substantially
less volume than the Exchange, and securities of some foreign companies are
less liquid and more volatile than securities of comparable U.S. companies.
Similarly, volume and liquidity in most foreign bond markets is less than in
the United States and, at times, volatility of price can be greater than in
the United States. Fixed commissions on foreign stock exchanges are generally
higher than negotiated commissions on U.S. exchanges, although the Portfolio
endeavors to achieve the most favorable net results on its portfolio
transactions. There is generally less government supervision and regulation of
stock exchanges, brokers and listed companies than in the United States. Mail
service between the United States and foreign countries may be slower or less
reliable than within the United States, thus increasing the risk of delayed
settlements of portfolio transactions or loss of certificates for portfolio
securities. Investments may include securities issued by companies in lesser-
developed countries, which are sometimes referred to as "emerging markets".
Such countries pose a heightened risk of nationalization or expropriation or
confiscatory taxation, political, financial or social instability, armed
conflict or diplomatic developments which could affect the Portfolio's
investments in those countries. Moreover, individual foreign economies may
differ favorably or unfavorably from the U.S. economy in such respects as
growth of gross national product, rate of inflation, capital reinvestment,
resource self-sufficiency and balance of payments position. Investments in
foreign securities are not expected to exceed 25% of total assets.


DERIVATIVE INSTRUMENTS.  The Portfolio may purchase or sell derivative
instruments (which are instruments that derive their value from another
instrument, security, index or currency) to hedge against fluctuations in
interest rates, securities prices or currency exchange rates to change the
duration of the Portfolio's fixed income portfolio or as a substitute for the
purchase or sale of securities or currency. Options may be written to enhance
income. The Portfolio's transactions in derivative instruments may include the
purchase or sale of futures contracts on securities, (such as U.S. Government
securities), indices, other financial instruments (such as certificates of
deposit, Eurodollar time deposits, and economic indices) or currencies;
options on futures contracts; exchange-traded options on securities, indices
or currencies; and forward contracts to purchase or sell currencies. All of
the Portfolio's transactions in derivative instruments involve a risk of loss
or depreciation due to: unanticipated adverse changes in interest rates,
securities prices or currency exchange rates; the inability to close out a
position; tax constraints on closing out positions; default by the
counterparty; imperfect correlation between a position and the desired hedge;
and portfolio management constraints on disposing of securities subject to
such transactions. The loss on derivative instruments (other than purchased
options) may substantially exceed the Portfolio's initial investment in these
instruments. In addition, the Portfolio may lose the entire premium paid for
purchased options that expire before they can be profitably exercised by the
Portfolio. The Portfolio incurs transaction costs in opening and closing
positions in derivative instruments. Under regulations of the Commodity Future
Trading Commission, the use of futures transactions for nonhedging purposes is
limited. There can be no assurance that the investment adviser's use of
derivative instruments will be advantageous to the Portfolio.

    The Portfolio's success in using derivative instruments to hedge portfolio
assets depends on the degree of price correlation between the derivative
instrument 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.

FORWARD FOREIGN CURRENCY EXCHANGE TRANSACTIONS. The Portfolio may enter into
forward foreign currency exchange contracts. A forward foreign currency
exchange contract involves an obligation to purchase or sell a specific
currency at a future date, which may be any fixed number of days from the date
of the contract agreed upon by the parties, at a price set at the time of the
contract. These 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.


    At the maturity of a forward contract the Portfolio may either accept or
make delivery of the currency specified in the contract or, at or prior to
maturity, enter into a closing transaction involving the purchase or sale of
an offsetting contract. Closing transactions with respect to forward contracts
are usually effected with the currency trader who is a party to the original
forward contract.


    The Portfolio will not enter into forward contracts or maintain a net
exposure to such contracts where the consummation of the contracts would
obligate the Portfolio to deliver an amount of foreign currency in excess of
the value of the securities held by the Portfolio or other assets denominated
in that currency. Under normal circumstances, consideration of the prospect
for currency parities will be incorporated into the long-term investment
decisions made with regard to overall diversification strategies. However, the
Portfolio believes that it is important to have the flexibility to enter into
such forward contracts when it determines that the best interests of the
Portfolio will be served. The Portfolio generally will not enter into a
forward contract with a term of greater than one year.


OPTIONS ON SECURITIES. An options position may be closed out only on an
options exchange which provides a secondary market for an option of the same
series. Although the Portfolio will generally purchase or write only those
options for which there appears to be an active secondary market, there is no
assurance that a liquid secondary market on an exchange will exist for any
particular option, or at any particular time. For some options, no secondary
market on an exchange may exist. In such event, it might not be possible to
effect closing transactions in particular options, with the result that the
Portfolio would have to exercise its options in order to realize any profit
and would incur transaction costs upon the sale of underlying securities
pursuant to the exercise of put options. If the Portfolio as a covered call
option writer is unable to effect a closing purchase transaction in a
secondary market, it will not be able to sell the underlying security until
the option expires or it delivers the underlying security upon exercise.

    Reasons for the absence of a liquid secondary market on an exchange
include the following: (i) there may be insufficient trading interest in
certain options; (ii) restrictions may be imposed by an exchange on opening
transactions or closing transactions or both; (iii) trading halts, suspensions
or other restrictions may be imposed with respect to particular classes or
series of options or underlying securities; (iv) unusual or unforeseen
circumstances may interrupt normal operations on an exchange; (v) the
facilities of an exchange or the Options Clearing Corporation ("OCC") may not
at all times be adequate to handle current trading volume; or (vi) one or more
exchanges could, for economic or other reasons, decide or be compelled at some
future date to discontinue the trading of options (or a particular class or
series of options), in which event the secondary market on that exchange (or
in that class or series of options) would cease to exist, although outstanding
options on that exchange that had been issued by the OCC as a result of trades
on that exchange would continue to be exercisable in accordance with their
terms.

    There is no assurance that higher than anticipated trading activity or
other unforeseen events might not, at times, render certain of the facilities
of the OCC inadequate, and thereby result in the institution by an exchange of
special procedures which may interfere with the timely execution of customers'
orders.

FUTURES CONTRACTS. All futures contracts entered into by the Portfolio are
traded on exchanges or boards of trade that are licensed and regulated by the
Commodity Futures Trading Commission ("CFTC"). The Portfolio may purchase and
write call and put options on futures contracts which are traded on a U.S.
exchange or board of trade.


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

    To the extent that the Portfolio enters into futures contracts, options on
futures contracts and options on foreign currencies traded on an exchange
regulated by the CFTC, 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 investments, after taking into account unrealized profits and
unrealized losses on any contracts the Portfolio has entered into.  The
Portfolio did not engage in such transactions during the fiscal year ended
March 31, 1999, and there is no assurance that it will engage in such
transactions in the future.

ASSET COVERAGE. Transactions involving forward contracts, futures contracts
and options (other than options that the Portfolio has purchased) expose the
Portfolio to an obligation to another party. The Portfolio will not enter into
any such transactions unless it owns either (1) an offsetting ("covered")
position in securities, or other options, futures contracts or forward
contracts, or (2) cash or liquid securities (such as readily marketable
obligations and money market instruments) 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 ("SEC")
guidelines regarding cover for these instruments and, if the guidelines so
require, set aside cash, or liquid securities in a segregated account with its
custodian in the prescribed amount. The securities in the segregated account
will be marked to market daily.


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


SECURITIES LENDING. The Portfolio may seek to increase its income by lending
portfolio securities to broker-dealers or other institutional borrowers. If
the management of the Portfolio decides to make securities loans, it is
intended that the value of the securities loaned would not exceed 30% of the
Portfolio's total assets. Securities lending involves risks of delay in
recovery or even loss of rights on the securities loaned if the borrower fails
financially. The Portfolio has no present intention of engaging in securities
lending.


INVESTMENT IN WARRANTS.  The Portfolio may invest in warrants which have no
voting rights, pay no dividends and have no rights with respect to the assets
of the corporation issuing them. Warrants basically are options to purchase
equity securities at a specific price valid for a specific period of time.
They do not represent ownership of the securities, but only the right to buy
them. Warrants differ from calls in that warrants are issued by the same
issuer as the security which may be purchased on their exercise, whereas calls
may be written or issued by anyone. The prices of warrants do not necessarily
move parallel to the prices of the underlying securities.

RESTRICTED SECURITIES. The Portfolio may invest up to 15% of net assets in
illiquid securities. Illiquid securities include securities legally restricted
as to resale, such as commercial paper issued pursuant to Section 4(2) of the
Securities Act of 1933, as amended, and securities eligible for resale
pursuant to Rule 144A thereunder. Section 4(2) and Rule 144A securities may,
however, be treated as liquid by the investment adviser pursuant to procedures
adopted by the Trustees, which require consideration of factors such as
trading activity, availability of market quotations and number of dealers
willing to purchase the security. If the Portfolio invests in Rule 144A
securities, the level of portfolio illiquidity may be increased to the extent
that eligible buyers become uninterested in purchasing such securities.

    It may be difficult to sell such securities at a price representing their
fair value until such time as such securities may by sold publicly. Where
registration is required, a considerable period may elapse between a decision
to sell the securities and the time when the Portfolio would be permitted to
sell. Thus, the Portfolio may not be able to obtain as favorable a price as
that prevailing at the time of the decision to sell. The Portfolio may also
acquire securities through private placements under which it may agree to
contractual restrictions on the resale of such securities. Such restrictions
might prevent their sale at a time when such sale would otherwise be
desirable.


DIVERSIFIED STATUS. The Portfolio is a "diversified" investment company under
the Investment Company Act of 1940 (the "1940 Act"). This means that with
respect to 75% of its total assets (1) the Portfolio may not invest more than
5% of its total assets in the securities of a single issuer (except U.S.
Government obligations) and (2) the Portfolio may not own more than 10% of the
outstanding voting securities of a single issuer which generally is
inapplicable because debt obligations are not voting securities.

PORTFOLIO TURNOVER. The Portfolio cannot accurately predict its portfolio
turnover rate, but it is anticipated that its annual turnover rate generally
may exceed 100% (excluding turnover of securities having a maturity of one
year or less). A 100% annual turnover rate could occur, for example, if all
the securities held by the Portfolio were replaced more than once in a period
of one year. A high turnover rate (100% or more) necessarily involves greater
brokerage expenses to the Portfolio and may result in the realization of
substantial net short-term capital gains, which are taxable as ordinary income
upon distribution to the Fund's shareholders.


                           INVESTMENT RESTRICTIONS


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


    (1) With respect to 75% of total assets of the Fund, purchase any security
if such purchase, at the time thereof, would cause more than 5% of the total
assets of the Fund (taken at market value) to be invested in the securities of
a single issuer, or cause more than 10% of the total outstanding 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
1940 Act;

    (3) Purchase securities on margin (but the Fund may obtain such short-term
credits as may be necessary for the clearance of purchases and sales of
securities). The deposit or payment by the Fund of initial, maintenance or
variation margin in connection with all types of options and futures contract
transactions is not considered the purchase of a security on margin;

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

    (5) Purchase any security if such purchase, at the time thereof, would
cause more than 25% of the Fund's total assets to be invested in any single
industry, provided that the electric, gas and telephone utility industries
shall be treated as separate industries for purposes of this restriction and
further provided that there is no limitation with respect to obligations
issued or guaranteed by the U.S. Government or any of its agencies or
instrumentalities.

    (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 physical commodities or contracts for the purchase or
sale of physical commodities; or

    (8) Make loans to any person except by (i) the acquisition of debt
securities and making portfolio investments, (ii) entering into repurchase
agreements or (iii) lending portfolio securities.

    With respect to restriction (5), the Fund will construe the phrase "more
than 25%" to be "25% or more".

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

    The Portfolio has adopted substantially the same fundamental investment
restrictions as the foregoing 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.


    The Fund and the Portfolio have each adopted the following investment
policies which may be changed by the Trustees with respect to the Fund without
shareholder approval or with respect to the Portfolio without approval of the
Fund or its other investors. The Fund and the Portfolio will not:


    (a) invest more than 15% of its net assets in investments which are not
readily marketable, including restricted securities and repurchase agreements
maturing in more than seven days. Restricted securities for the purposes of
this limitation do not include securities eligible for resale pursuant to Rule
144A under the Securities Act of 1933 and commercial paper issued pursuant to
Section 4(2) of said Act that the Board of Trustees of the Trust or the
Portfolio, or their delegate, determines to be liquid, based upon the trading
markets for the specific security. Any such determination by a delegate will
be made pursuant to procedures adopted by the Board. If the Fund or Portfolio
invests in Rule 144A securities, the level of portfolio illiquidity may be
increased to the extent that eligible buyers become uninterested in purchasing
such securities; or

    (b) make short sales of securities or maintain a short position, unless at
all times when a short position is open it owns an equal amount of such
securities or securities convertible into or exchangeable for, without payment
of any further consideration, securities of the same issuer as, and equal in
amount to, the securities sold short, and unless not more than 25% of its net
assets (taken at current value) is held as collateral for such sales at any
one time.


    For as long as a feeder fund of the Portfolio has registered shares in
Hong Kong (and for so long as Hong Kong requires the following restrictions),
the Portfolio may not (i) invest more than 10% of its net assets in the
securities of any one issuer or, purchase more than 10% of the ordinary shares
of any one issuer, provided, however, up to 30% of the Portfolio's net asset
value may be invested in Government and public securities of the same issue;
and the Portfolio may invest all of its assets in Government and other public
securities in at least six different issues, (ii) invest more than 15% of net
assets in securities which are not listed or quoted on any stock exchange,
over-the-counter market or other organized securities market that is open to
the international public and on which such securities are regularly traded (a
"Market"), (iii) invest more than 15% of net assets in warrants and options
for non-hedging purposes, (iv) write call options on Portfolio investments
exceeding 25% of its total net asset value in terms of exercise price, (v)
enter into futures contracts on an unhedged basis where the net total
aggregate value of contract prices, whether payable by or to the Portfolio
under all outstanding futures contracts, together with the aggregate value of
holdings under (vi) below exceeds 20% of the net asset value of the Portfolio,
(vi) invest in physical commodities (including gold, silver, platinum or other
bullion) and commodity based investments (other than shares in companies
engaged in producing, processing or trading in commodities) which value
together with the net aggregate value of the holdings described in (v) above,
exceeds 20% of the Portfolio's net asset value, (vii) purchase shares of other
investment companies exceeding 10% of net assets. In addition, the investment
objective of any scheme in which any Portfolio invests must not be to invest
in investments prohibited by this undertaking and where the scheme's
investment objective is to invest primarily in investments which are
restricted by this undertaking, such holdings must not be in contravention of
the relevant limitation, (viii) borrow more than 25% of its net assets
(provided that for the purposes of this paragraph, back to back loans are not
to be categorized as borrowings), (ix) write uncovered options, (x) invest in
real estate (including options, rights or interests therein but excluding

net assets provided that any security which a Portfolio does sell short must
be actively traded on a market, (xiii) subject to paragraph (v) above,

partly-paid securities unless any call thereon could be met in full out of
cash or near cash held by it in the amount of which has not already been taken
into account for the purposes of (ix) above.

    Whenever an investment policy or investment restriction set forth in the
prospectus or this SAI states a maximum percentage of assets that may be
invested in any security or other asset, or describes a policy regarding
quality standards such percentage limitation or standard shall be determined
immediately after and as a result of the Fund's or the Portfolio's acquisition
of such security or asset. Accordingly, any later increase or decrease
resulting from a change in values, assets or other circumstances, will not
compel the Fund or the Portfolio, as the case may be, to dispose of such
security or other asset. Where applicable and notwithstanding the foregoing,
under normal market conditions the Fund and the Portfolio must take actions
necessary to comply with the policy of investing at least 65% of total assets
in the lowest investment grade and lower rated and unrated debt obligations.
Moreover, the Fund and Portfolio must always be in compliance with the
limitation on investing in illiquid securities and the borrowing policies set
forth above.

    The Nominating Commitee of the Board of Trustees of the Trust and the
Portfolio is comprised of all Trustees who are not "interested persons" as
that term is defined by the 1940 Act ("noninterested Trustees"). The purpose
of the Committee is to recommend to the Board nominees for the position of
noninterested Trustee and to assure that at least a majority of the Board of
Trustees is independent of Eaton Vance and its affiliates.

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

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

    Trustees of the Portfolio who are not affiliated with the investment
adviser may elect to defer receipt of all or a percentage of their annual fees
in accordance with the terms of a Trustees Deferred Compensation Plan (the
"Trustees" Plan"). Under the Trustees' Plan, an eligible Trustee may elect to
have his deferred fees invested by the 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 Trustees' Plan will be determined based upon the performance of such
investments. Deferral of Trustees' fees in accordance with the Trustees' Plan
will have a negligible effect on the 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. Neither the Portfolio nor the Trust has a
retirement plan for its Trustees.

    The fees and expenses of the noninterested Trustees of the Trust and of
the Portfolio 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 Trust
or the Portfolio.) During the fiscal year ended March 31, 1999, the
noninterested Trustees of the Trust and the Portfolio earned the following
compensation in their capacities as Trustees from the Trust and the Portfolio,
and for the year ended December 31, 1998, earned the following compensation in
their capacities as Trustees of the funds in the Eaton Vance fund complex(1):

</TABLE>

ORGANIZATION. The Fund is a series of the Trust, which is organized under
Massachusetts law as a business trust and is operated as an open-end
management investment company. The Trust changed its name from Eaton Vance
Government Obligations Trust on July 10, 1995. The Fund was reorganized into
multiple classes and changed its name to Eaton Vance High Income Fund on April
1, 1998. The operations of Class B reflect the operations of the Fund prior to
April 1, 1998. Class C is the successor to the operations of a separate series
of the Trust.

    The Trust may issue an unlimited number of shares of beneficial interest
(no par value per share) in one or more series (such as the Fund). The
Trustees of the Trust have divided the shares of the Fund into multiple
classes. Each class represents an interest in the Fund, but is subject to
different expenses, rights and privileges. The Trustees have the authority
under the Declaration of Trust to create additional classes of shares with
differing rights and privileges. When issued and outstanding, shares are fully
paid and nonassessable by the Trust. Shareholders are entitled to one vote for
each full share held. Fractional shares may be voted proportionately.  Shares
of the Fund will be voted together except that only shareholders of a
particular class may vote on matters affecting only that class. Shares have no
preemptive or conversion rights and are freely transferable. In the event of
the liquidation of the Fund, shareholders of each class are entitled to share
pro rata in the net assets attributable to that class available for
distribution to shareholders.


    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 growth in the assets of the Portfolio,
may afford the potential for economies of scale for the Fund and may over time
result in lower expenses for the Fund.

    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 investors about such a meeting.


    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, the financial interests of which are 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 any series or to make such
other changes (such as reclassifying series or classes of shares or
restructuring the Trust) as do not have a materially adverse effect on the
financial interests of shareholders or if they deem it necessary to conform it
to applicable federal or state laws or regulations. The Trust or any series or
class thereof may be terminated by: (1) the affirmative vote of the holders of
not less than two-thirds of the shares outstanding and entitled to vote at any
meeting of shareholders of the Trust or the appropriate series or class
thereof, or by an instrument or instruments in writing without a meeting,
consented to by the holders of two-thirds of the shares of the Trust or a
series or class thereof, provided, however, that, if such termination is
recommended by the Trustees, the vote of a majority of the outstanding voting
securities of the Trust or a series or class thereof entitled to vote thereon
will be sufficient authorization; or (2) by means of an instrument in writing
signed by a majority of the Trustees, to be followed by a written notice to
shareholders stating that a majority of the Trustees has determined that the
continuation of the Trust or a series or a class thereof is not in the best
interest of the Trust, such series or class or of their respective
shareholders.

    The Declaration of Trust further provides that the Trustees will not be
liable for errors of judgment or mistakes of fact or law; but nothing in the
Declaration of Trust protects a Trustee against any liability to which he
would otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence, or reckless disregard of the duties involved in the conduct of his
office.


    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. (The Declaration of Trust also contains provisions
limiting the liability of a series or class to that series or class.)
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 remote.

    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. 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 of the Portfolio
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 shares
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 communication with
shareholders about such a meeting.


    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.

    Whenever the Fund as an investor in a 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 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. 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, the 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 (or the assets of another investor in the Portfolio) from the
Portfolio.

               INVESTMENT ADVISORY AND ADMINISTRATIVE SERVICES

INVESTMENT ADVISORY SERVICES. 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.


    For a description of the compensation that the Portfolio pays BMR, see the
prospectus. As at March 31, 1999, the Portfolio had net assets of
$1,039,222,599. For the fiscal years ended March 31, 1999, 1998 and 1997, the
Portfolio paid BMR advisory fees of $5,895,549, $4,736,709 and $3,683,894,
respectively, (equivalent to 0.61%, 0.58% and 0.61% of the Portfolio's average
daily net assets for each such year).


    The Investment Advisory Agreement with BMR continues in effect from year
to year for so long as such continuance is approved at least annually (i) by
the vote of a majority of the noninterested Trustees of the Portfolio 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 (60) days' written
notice by the Board of Trustees of either party, or by vote of the majority of
the outstanding voting securities of the Portfolio, and the Agreement will
terminate automatically in the event of its assignment. The Agreement provides
that BMR may render services to others. The Agreement also provides that BMR
shall not be liable for any loss incurred in connection with the performance
of its duties, or action taken or omitted under that Agreement, in the absence
of willful misfeasance, bad faith, gross negligence in the performance of its
duties or by reason of its reckless disregard of its obligations and duties
thereunder, or for any losses sustained in the acquisition, holding or
disposition of any security or other investment.


ADMINISTRATIVE SERVICES. As indicated in the prospectus, Eaton Vance serves as
administrator of the Fund, but currently receives no compensation for
providing administrative services to the Fund. Under its Administrative
Services Agreement with the Trust, 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.

EXPENSES. The Fund and Portfolio are each responsible for all expenses not
expressly stated to be payable by another party (such as the investment
adviser under the Investment Advisory Agreement, Eaton Vance under the
Administrative Services Agreement or the principal underwriter under the
Distribution Agreement). In the case of expenses incurred by the Trust, the
Fund is responsible for its pro rata share of those expenses. The only
expenses of the Fund allocated to a particular class are those incurred under
the Distribution Plan applicable to that class and the fee paid to the
principal underwriter for handling repurchase transactions.


                           OTHER SERVICE PROVIDERS


PRINCIPAL UNDERWRITER. Eaton Vance Distributors, Inc. ("EVD"), The Eaton Vance
Building, 255 State Street, Boston, MA 02109, is the Fund's principal
underwriter. The principal underwriter acts as principal in selling shares
under a Distribution Agreement with the Trust. The expenses of printing copies
of prospectuses used to offer shares and other selling literature and of
advertising are 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 are borne by
the Fund. The Distribution Agreement as it applies to Class B and Class C
shares is renewable annually by the Trust's Board of Trustees (including a
majority of the noninterested Trustees who have no direct or indirect
financial interest in the operation of the 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 shares of the
relevant class or on six months' notice by the principal underwriter and is
automatically terminated upon assignment. The principal underwriter
distributes shares on a "best efforts" basis under which it is required to
take and pay for only such shares as may be sold. The principal underwriter
allows investment dealers discounts from the applicable public offering price
which are alike for all investment dealers. See "Sales Charges." EVD is a
wholly-owned subsidiary of EVC. Mr. Hawkes is a Vice President and Director
and Messrs. Dynner and O'Connor are Vice Presidents of EVD.


CUSTODIAN.  Investors Bank & Trust Company ("IBT"), 200 Clarendon Street,

provides services in connection with the preparation of shareholder reports
and the electronic filing of such reports with the SEC. EVC and its affiliates
and their officers and employees from time to time have transactions with
various banks, including IBT. It is Eaton Vance's opinion that the terms and
conditions of such transactions were not and will not be influenced by
existing or potential custodial or other relationships between the Fund or the
Portfolio and such banks.


INDEPENDENT ACCOUNTANTS. Deloitte & Touche LLP, 200 Berkeley Street, Boston,
Massachusetts 02116, are the independent accountants of the Fund and the
Portfolio, providing audit services, tax return preparation, and assistance

CALCULATION OF NET ASSET VALUE. The net asset value of the Portfolio is
computed by IBT (as agent and custodian for the Portfolio) by subtracting the
liabilities of the Portfolio from the value of its total assets. 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, Martin
Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence
Day, Labor Day, Thanksgiving Day and Christmas Day.

    The Trustees of the Portfolio have established the following procedures
for the fair valuation of the Portfolio's assets under normal market
conditions. Securities listed on foreign or U.S. securities exchanges or in
the NASDAQ National Market System generally are valued at closing sale prices
or, if there were no sales, at the mean between the closing bid and asked
prices therefor on the exchange where such securities are principally traded
or on such National Market System. Unlisted or listed securities for which
closing sale prices are not available are valued at the mean between the
latest bid and asked prices. An option is valued at the last sale price as
quoted on the principal exchange or board of trade on which such option or
contract is traded, or in the absence of a sale, at the mean between the last
bid and asked prices. Futures positions on securities or currencies are
generally valued at closing settlement prices. Short-term debt securities with
a remaining maturity of 60 days or less are valued at amortized cost. If
securities were acquired with a remaining maturity of more than 60 days, their
amortized cost value will be based on their value on the sixty-first day prior
to maturity. Other fixed income and debt securities, including listed
securities and securities for which price quotations are available, will
normally be valued on the basis of valuations furnished by a pricing service.
All other securities are valued at fair value as determined in good faith by
or at the direction of the Trustees.


    Generally, trading in the foreign securities owned by the Portfolio is
substantially completed each day at various times prior to the close of the
New York Stock Exchange (the "Exchange"). The values of these securities used
in determining the net asset value of the Portfolio's shares generally are
computed as of such times. Occasionally, events affecting the value of foreign
securities may occur between such times and the close of the Exchange which
will not be reflected in the computation of the Portfolio's net asset value
(unless the Portfolio deems that such events would materially affect its net
asset value, in which case an adjustment would be made and reflected in such
computation). Foreign securities and currency held by the Portfolio will be
valued in U.S. dollars; such values will be computed by the custodian based on
foreign currency exchange rate quotations supplied by an independent quotation
service.

    Each investor in the Portfolio, including the Fund, may add to or reduce
its investment in the Portfolio on each day 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.


ADDITIONAL INFORMATION ABOUT PURCHASES. Fund shares are continuously offered
through investment dealers which have entered agreements with the principal
underwriter. The public offering price is the net asset value next computed
after receipt of the order.

    In connection with employee benefit or other continuous group purchase
plans, 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 below.


SUSPENSION OF SALES. The Trust may, in its absolute discretion, suspend,
discontinue or limit the offering of one or more of its classes of shares at
any time. In determining whether any such action should be taken, the Trust's
management intends to consider all relevant factors, including (without
limitation) the size of the Fund or class, the investment climate and market
conditions, the volume of sales and redemptions of shares, and in the case of
Class B and Class C shares, the amount of uncovered distribution charges of
the principal underwriter. The Class B and Class C Distribution Plans may
continue in effect and payments may be made under the Plans following any such
suspension, discontinuance or limitation of the offering of shares; however,
there is no contractual obligation to continue any Plan for any particular
period of time. Suspension of the offering of shares would not, of course,
affect a shareholder's ability to redeem 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. The minimum value of securities (or securities and cash)
accepted for deposit is $5,000. Securities accepted will be sold on the day of
their receipt 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 net asset value of Class B and Class C
shares 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 investment
dealer, together with a completed and signed Letter of Transmittal in approved
form (available from investment dealers). Investors who are contemplating an
exchange of securities for shares, or their representatives, must contact
Eaton Vance to determine whether the securities are acceptable before
forwarding such securities. Eaton Vance reserves the right to reject any
securities. Exchanging securities for 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.


ADDITIONAL INFORMATION ABOUT REDEMPTIONS. 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 SEC, or during any emergency as determined by the SEC 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 SEC for the
protection of investors.


    While normally payments will be made 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 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.

    Due to the high cost of maintaining small accounts, the Trust reserves the
right to redeem accounts with balances of less than $750. Prior to such a
redemption, shareholders will be given 60 days' written notice to make an
additional purchase. However, no such redemption would be required by the
Trust if the cause of the low account balance was a reduction in the net asset
value of shares. No CDSC will be imposed with respect to such involuntary
redemptions.

SYSTEMATIC WITHDRAWAL PLAN. The transfer agent will send to the shareholder
regular monthly or quarterly payments of any permitted amount designated by
the shareholder based upon the value of the shares held. The checks will be
drawn from share redemptions and hence, may require the recognition of taxable
gain or loss. Income dividends and capital gains distributions in connection
with withdrawal plan 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.  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. The shareholder, the transfer agent
or the principal underwriter will be able to terminate the withdrawal plan at
any time without penalty.

                                SALES CHARGES


DEALER COMMISSIONS. The principal underwriter may, from time to time, at its
own expense, provide additional incentives to investment dealers which employ
registered representatives who sell Fund shares and/or shares of other funds
distributed by the principal underwriter. In some instances, such additional
incentives may be offered only to certain investment dealers whose
representatives sell or 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 investment dealers.

TAX-SHELTERED RETIREMENT PLANS.  Class C shares are available for purchase in
connection with certain tax-sheltered retirement plans. 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. Participant accounting services
(including trust fund reconciliation services) will be offered only through
third party recordkeepers and not by the principal underwriter. Under all
plans, dividends and distributions will be automatically reinvested in
additional shares.


CDSC WAIVERS. The CDSC applicable to Class B shares will be waived in
connection with minimum required distributions from tax-sheltered retirement
plans by applying the rate required to be withdrawn under the applicable rules
and regulations of the Internal Revenue Service to the balance of Class B
shares in your account.


DISTRIBUTION PLANS.  The Trust has adopted compensation-type Distribution
Plans (the "Class B and Class C Plans") pursuant to Rule 12b-1 under the 1940
Act for the Fund's Class B and Class C shares. The Class B and Class C Plans
are designed to permit an investor to purchase shares through an investment
dealer without incurring an initial sales charge and at the same time permit
the principal underwriter to compensate investment dealers in connection
therewith. The Class B and Class C Plans provide that the Fund will pay sales
commissions and distribution fees to the principal underwriter only after and
as a result of the sale of shares. On each sale of shares (excluding
reinvestment of distributions), the Fund will pay the principal underwriter
amounts representing (i) sales commissions equal to 5% for Class B shares and
6.25% for Class C shares 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. To pay these amounts, each Class pays the principal underwriter a
fee, accrued daily and paid monthly, at an annual rate not exceeding .75% of
its average daily net assets to finance the distribution of its shares. Such
fees compensate the principal underwriter for sales commissions paid by it to
investment dealers on the sale of shares and for interest expenses. For sales
of Class B shares, the principal underwriter uses its own funds to pay sales
commissions (except on exchange transactions and reinvestments) to investment
dealers at the time of sale equal to 4% of the purchase price of the Class B
shares sold by such dealers. For Class C shares, the principal underwriter
currently expects to pay to an investment dealer (a) sales commissions (except
on exchange transactions and reinvestments) at the time of sale equal to .75%
of the purchase price of the shares sold by such dealer, and (b) monthly sales
commissions approximately equivalent to  1/12 of .75% of the value of shares
sold by such dealer and remaining outstanding for at least one year. During
the first year after a purchase of Class C shares, the principal underwriter
will retain the sales commission as reimbursement for the sales commissions
paid to investment dealers at the time of sale. CDSCs paid to the principal
underwriter will be used to reduce amounts owed to it. The Class B and Class C
Plans provide that the Fund 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. CDSCs and accrued amounts will be paid
by the Trust to the principal underwriter whenever there exist uncovered
distribution charges. Because payments to the principal underwriter under the
Class B and Class C Plans are limited, uncovered distribution charges (sales
commissions paid by the principal underwriter plus interest, less the above
fees and CDSCs received by it) may exist indefinitely. For the sales
commissions and CDSCs paid on (and uncovered distribution charges of) Class B
and Class C shares, see Appendix A and Appendix B, respectively.


    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 Class B and Class C Plans by the Trust to the principal
underwriter and CDSCs 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 shares, the nature of such sales (i.e., whether
they result from exchange transactions, reinvestments or from cash sales
through investment dealers), the level and timing of redemptions of shares
upon which a CDSC will be imposed, the level and timing of redemptions of
shares upon which no CDSC will be imposed (including redemptions of shares
pursuant to the exchange privilege which result in a reduction of uncovered
distribution charges), changes in the level of the net assets of the Class,
and changes in the interest rate used in the calculation of the distribution
fee under the Class B and Class C Plans.


    The Class B and Class C Plans also authorize each Class to make payments
of service fees to the principal underwriter, investment dealers and other
persons in amounts not exceeding 0.25% of its average daily net assets for
personal services, and/or the maintenance of shareholder accounts. This fee is
paid quarterly in arrears based on the value of Class B shares sold by such
persons and remaining outstanding for at least twelve months. For Class C,
investment dealers currently receive (a) a service fee (except on exchange
transactions and reinvestments) at the time of sale equal to 0.25% of the
purchase price of the Class C shares sold by such dealer, and (b) monthly
service fees approximately equivalent to  1/12 of 0.25% of the value of Class
C shares sold by such dealer and remaining outstanding for at least one year.
During the first year after a purchase of Class C shares, the principal
underwriter will retain the service fee as reimbursement for the service fee
payment made to investment dealers at the time of sale. For the service fees
paid by Class B and Class C shares, see Appendix A and Appendix B,
respectively.


    Currently, payments of sales commissions and distribution fees and of
service fees may equal 1% of a Class's average daily net assets per annum. The
Trust 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 Class B and Class C Plans through an
increase in the Fund's assets (thereby increasing the advisory fee payable to
BMR by the Portfolio) resulting from sale of shares and through the amounts
paid to the principal underwriter, including CDSCs, pursuant to the Plans. The
Eaton Vance organization may be considered to have realized a profit under the
Class B and Class C Plans if at any point in time the aggregate amounts
theretofore received by the principal underwriter pursuant to the Class B or
Class C Plan and from CDSCs have exceeded the total expenses theretofore
incurred by such organization in distributing shares. 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 Trust.

    The Class B and Class C Plans continue in effect from year to year so long
as such continuance is approved at least annually by the vote of both a
majority of (i) the noninterested Trustees of the Trust who have no direct or
indirect financial interest in the operation of the Plan or any agreements
related to the Plan (the "Plan Trustees") and (ii) all of the Trustees then in
office. Each Plan may be terminated at any time by vote of a majority of the
Plan Trustees or by a vote of a majority of the outstanding voting securities
of the applicable Class. Each Plan requires quarterly Trustee review of a
written report of the amount expended under the Plan and the purposes for
which such expenditures were made. The Plans may not be amended to increase
materially the payments described therein without approval of the shareholders
of the affected Class and the Trustees. So long as a Plan is in effect, the
selection and nomination of the noninterested Trustees shall be committed to
the discretion of such Trustees. The Class B and Class C Plans were initially
approved by the Trustees, including the Plan Trustees, on June 23, 1997.

    The Trustees of the Trust believe that each Plan will be a significant
factor in the expected growth of each Fund's assets, and will result in
increased investment flexibility and advantages which have benefitted and will
continue to benefit the Fund and its shareholders. Payments for sales
commissions and distribution fees made to the principal underwriter under the
Class B and Class C Plans will compensate the principal underwriter for its
services and expenses in distributing those classes of shares. Service fee
payments made to the principal underwriter and investment dealers provide
incentives to provide continuing personal services to investors and the
maintenance of shareholder accounts.  By providing incentives to the principal
underwriter and investment dealers, each 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 each
Plan will benefit the Fund and its shareholders.

                                 PERFORMANCE

    Average annual total return is determined separately for each Class of the
Fund by multiplying a hypothetical initial purchase order of $1,000 by the
average annual compound rate of return (including capital appreciation/
depreciation, and distributions paid and reinvested) for the stated period and
annualizing the result. The  calculation assumes (i) that all distributions
are reinvested at net asset value on the reinvestment dates during the period,
(ii) a complete redemption of the investment and, (iii) the deduction of any
CDSC at the end of the period. The Fund may also publish total return figures
for each class based on reduced sales charges or at net asset value. These
returns would be lower if the full sales charge was imposed. For further
information concerning the total return of the Classes of the Fund, see
Appendix A and Appendix B.


    Yield is computed separately for each Class of the Fund pursuant to a
standardized formula by dividing the net investment income per share earned
during a recent thirty-day period by the maximum offering price per share on
the last day of the period and annualizing the resulting figure. Net
investment income per share is calculated from the yields to maturity of all
debt obligations held by the Portfolio based on prescribed methods, reduced by
accrued Fund and Class expenses for the period with the resulting number being
divided by the average daily number of Class shares outstanding and entitled
to receive distributions during the period. This yield figure does not reflect
the deduction of any CDSCs which (if applicable) are imposed upon certain
redemptions at the rates set forth under "Sales Charges" in the prospectus.

                                    TAXES


    Each series of the Trust is treated as a separate entity for federal
income tax purposes. The Fund has elected to be treated, has qualified and
intends to continue to qualify each year as a regulated investment company
("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 substantially all of its net income and net short-
term and long-term capital gains in accordance with the timing requirements
imposed by the Code, so as to maintain its RIC status and avoid paying any
federal income or excise tax. The Fund so qualified for its taxable year ended
March 31, 1999. 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 also satisfy these
requirements. 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 (i) will be deemed to own its proportionate
share of each of the assets of the Portfolio and (ii) will be entitled to the
gross income of the Portfolio attributable to such share.

    In order to avoid incurring a federal excise tax obligation, 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 for such
year, at least 98% of its capital gain net income (which is the excess of its
realized capital gains over its realized capital losses, generally computed on
the basis of the one-year period ending on October 31 of such year), after
reduction by (i) any available capital loss carryforwards and (ii) 100% of any
income from the prior year (as previously computed) that was not paid out
during such year and on which the Fund paid no federal income tax. Under
current law, provided that the Fund qualifies as a RIC and the Portfolio is
treated as a partnership for Massachusetts and federal tax purposes, neither
the Fund nor the Portfolio should be liable for any income, excise or
franchise tax in the Commonwealth of Massachusetts.

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

    The Fund's distributions of net investment income and the excess of net
short-term capital gain over net long-term capital loss and certain foreign
exchange gains earned by the Portfolio and allocated to the Fund are taxable
to shareholders of the Fund as ordinary income, whether received in cash or
reinvested in additional shares. The Fund's distributions of the excess of net
long-term capital gain over net short-term capital loss (including any capital
loss 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 reinvested in additional shares, and
regardless of the length of time their shares have been held. Dividends
declared by the Fund in October, November or December as of a record date in
such a month that are paid the following January are treated under the Code as
if they were received on December 31 of the year in which they are declared.

    Distributions of capital gains by the Fund reduce the net asset value of
the Fund's shares. Should such a distribution reduce the net asset value below
a shareholder's tax basis, such distribution would be taxable to the
shareholder even though, from an investment standpoint, it may constitute a
return of a portion of the purchase price. Therefore, investors should
consider the tax implications of buying shares immediately before a
distribution of capital gains.

    Distributions made by the Fund, if any, that 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 Fund shares with respect to which the dividends are received are
treated as debt-financed under 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, which must be satisfied separately for each dividend during a
specified period. Receipt of certain distributions qualifying for the
deduction may result in reduction of the tax basis of the corporate
shareholder's Fund shares and require current income recognition to the extent
in excess of such basis. Distributions eligible for the dividends-received
deduction may give rise to or increase an alternative minimum tax for
corporation.

    The Portfolio may be subject to foreign income tax withholding or other
foreign taxes with respect to income (possibly including, in some cases,
capital gains) from certain foreign securities. These taxes may be reduced or
eliminated under the terms of an applicable tax convention between certain
countries and the U.S. 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. Accordingly, under the
Code, the Fund will not be eligible to pass through to its shareholders their
proportionate share of any foreign taxes paid by the Portfolio and allocated
to the Fund and shareholders will not be entitled to any related foreign tax
credits or deductions. Certain foreign exchange gains and losses realized by
Portfolio and allocated to the Fund in connection with the Portfolio's
investment in foreign securities, foreign currency, and foreign currency-
related options, futures or forward contracts may be treated as ordinary
income and losses. Certain uses of foreign currency and foreign currency
options, futures and forward contracts and investment by the Portfolio in
certain "passive foreign investment companies" ("PFICs") may be limited or a
tax election may be made, if available, in order to seek to preserve the
Fund's qualification as a RIC and/or avoid imposition of an income tax on the
Fund.

    The Portfolio's investment in zero coupon, deferred interest and certain
pay-in-kind or other debt securities issued with original issue discount will
cause it to realize income prior to the receipt of cash payments with respect
to these securities. Such income will be allocated daily to interests in the
Portfolio and, in order to enable the Fund to distribute its proportionate
share of this income and avoid a tax payable by the Fund, the Portfolio may be
required to liquidate securities that it might otherwise have continued to
hold in order to generate cash that the Fund may withdraw from the Portfolio
to make distributions to Fund shareholders. Acquiring securities at a market
discount may have the same effect if an election is made to include accrued
market discount in income currently.


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

    Any loss realized upon the sale 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 treated as long-term capital gains with
respect to such shares. All or a portion of any loss realized upon a taxable
disposition of Fund shares may be disallowed under "wash sale" rules if other
shares of the Fund are purchased (whether through the reinvestment of
distributions or otherwise) within 30 days before or after such disposition.

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


    Non-resident alien individuals, foreign corporations and certain 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 convention.
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: (i) the shareholder is engaged in a trade or business in the
United States; (ii) the shareholder 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 (iii) the shareholder fails to provide, or renew after
expiration, any required certifications regarding its 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 these or other special
tax rules that may apply in their particular situations, as well as the state,
local, and, where applicable, foreign tax consequences of investing in the
Fund.


                       PORTFOLIO SECURITY TRANSACTIONS


    Decisions concerning the execution of portfolio security transactions,
including the selection of the market and the executing firm, are made by BMR.
BMR is also responsible for the execution of transactions for all other
accounts managed by it. BMR places the portfolio security transactions of the
Portfolio and of all other accounts managed by it for execution with many
broker-dealer firms. BMR uses its best efforts to obtain execution of
portfolio security transactions at prices which are advantageous to the
Portfolio and at reasonably competitive spreads or (when a disclosed
commission is being charged) at reasonably competitive commission rates. In
seeking such execution, BMR will use its best judgment in evaluating the terms
of a transaction, and will give consideration to various relevant factors
including without limitation the full range and quality of the executing
firm's services, the value of the brokerage and research services provided,
the responsiveness of the firm to BMR, size and type of the transaction, the
general execution and operational capabilities of the executing firm, 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 firm, the
value and quality of services rendered by the firm in other transactions, and
the reasonableness of the commission or spread, 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 executing firms, and a particular firm 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 firms who were selected to execute transactions on behalf of the
Portfolio and BMR's other clients for providing brokerage and research
services to BMR.

    As authorized in Section 28(e) of the Securities Exchange Act of 1934, a
broker or dealer who executes a portfolio transaction on behalf of the
Portfolio may receive a commission 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 compensation was
reasonable in relation to the value of the brokerage and research services
provided. This determination may be made either on the basis of that
particular transaction or on the basis of overall responsibilities 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; 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, analytical, statistical and quotation services, data, information
and other services, products and materials which assist such advisers in the
performance of their investment responsibilities ("Research Services") from
broker-dealer firms which execute portfolio transactions for the clients of
such advisers and from third parties with which such broker-dealers have
arrangements. Consistent with this practice, 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, political,
business and market information, industry and company reviews, evaluations of
securities and portfolio strategies and transactions, proxy voting data and
analysis services, technical analysis of various aspects of the securities
markets, 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 portfolio security transactions 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.


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


    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 NASD, which rule
provides that no firm which is a member of the NASD shall favor or disfavor
the distribution of shares of any particular investment company or group of
investment companies on the basis of brokerage commissions received or
expected by such firm from any source.

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


    For the fiscal years ended March 31, 1999 and 1998, the Portfolio paid
brokerage commissions of $682 and $5,287, respectively,  on portfolio security
transactions, all of which was paid in respect of portfolio security
transactions aggregating $307,774 and $2,552,494, respectively, to firms which
provided some research services to Eaton Vance (although many of such firms
may have been selected in any particular transaction primarily because of
their execution capabilities). For the fiscal year ended March 31, 1997 the
Portfolio paid no brokerage commissions on portfolio security transactions.


                             FINANCIAL STATEMENTS


    The audited financial statements of, and the independent auditors' report
for the Fund and the Portfolio, appear in the Fund's most recent annual report
to shareholders, which is incorporated by reference into this SAI. A copy of
the Fund's annual report accompanies this SAI. Consistent with applicable law,
duplicate mailings of shareholder reports and certain other Fund information
to shareholders residing at the same address may be eliminated.

    Registrant incorporates by reference the audited financial information for
the Fund and the Portfolio for the fiscal year ended March 31, 1999 as

                   CLASS B FEES, PERFORMANCE AND OWNERSHIP
DISTRIBUTION AND SERVICE FEES
    During the fiscal year ended March 31, 1999, the principal underwriter
paid to investment dealers sales commissions of $4,560,179 on sales of Class B
shares. During the same period, the Fund made distribution payments to the
principal underwriter under the Distribution Plan aggregating $4,933,989, and
the principal underwriter received approximately $1,527,000 in CDSCs imposed
on early redeeming shareholders. These distribution payments and CDSC payments
reduced uncovered distribution charges under the Plan. As at March 31, 1999
the outstanding uncovered distribution charges of the principal underwriter
calculated under the Plan amounted to approximately $17,602,000 (which amount
was equivalent to approximately 2.6% of the net assets attributable to Class B
on such day). During the fiscal year ended March 31, 1999, Class B made
service fee payments to the principal underwriter and investment dealers
aggregating $1,387,362 of which $1,379,504 was paid to investment dealers and
the balance of which was retained by the principal underwriter.

PRINCIPAL UNDERWRITER
    The Trust has authorized 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. For the fiscal year ended March 31,
1999, Class B paid the principal underwriter $14,620 for repurchase
transactions handled by it.


                           PERFORMANCE INFORMATION


    The table below indicates the cumulative and average annual total return
on a hypothetical investment of $1,000 in Class B shares for the periods shown
in the table. Past performance is no guarantee of future results. Investment
return and principal value will fluctuate; shares, when redeemed, may be worth
more or less than their original cost.

owned in the aggregate less than 1% of the outstanding Class B shares of the
Fund. As of June 30, 1999, Merrill Lynch, Pierce, Fenner & Smith, Inc.,
Jacksonville, FL was the record owner of approximately 26.0% of the
outstanding Class B shares, which were held on behalf of its customers who are
the beneficial owners of such shares, and as to which it had voting power

DISTRIBUTION AND SERVICE FEES
    During the fiscal year ended March 31, 1999, the principal underwriter
paid to investment dealers sales commissions of $202,207 on sales of Class C
shares. During the same period, the Fund made distribution payments to the
principal underwriter under the Distribution Plan aggregating $325,361 and the
principal underwriter received approximately $20,000 in CDSCs imposed on early
redeeming shareholders. These distribution payments and CDSC payments reduced
uncovered distribution charges under the Plan. As at March 31, 1999, the
outstanding uncovered distribution charges of the principal underwriter
calculated under the Plan amounted to approximately $4,605,000 (which amount
was equivalent to approximately 7.5% of the net assets attributable to Class C
on such day). During the fiscal year ended March 31, 1999, Class C made
service fee payments to the principal underwriter and investment dealers
aggregating $106,905 of which $50,341 was paid to investment dealers and the
balance of which was retained by the principal underwriter.

PRINCIPAL UNDERWRITER
    The Trust has authorized the principal underwriter to act as its agent in
repurchasing shares at the rate of $2.50 for each repurchase transaction

    The table below indicates the cumulative and average annual total return
on a hypothetical investment of $1,000 in Class C shares for the periods shown
in the table. Total return for the period prior to April 1, 1998 reflects the
total return of the predecessor to Class C. Total return prior to the
Predecessor Fund's commencement of operations reflects the total return of
Class B, adjusted to reflect the Class C sales charge. The Class B total
return has not been adjusted to reflect certain other expenses (such as
distribution and/or service fees). If such adjustments were made, the Class C
total return would be different. Past performance is no guarantee of future
results. Investment return and principal value will fluctuate; shares, when
redeemed, may be worth more or less than their original cost. Two asterisk(**)
indicates subsidized expenses. Returns would have been lower without
subsidies.

                                  APPENDIX D

                DESCRIPTION OF MOODY'S CORPORATE BOND RATINGS:

Aaa: Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edged." Interest payments are protected by a large or by an
exceptionally stable margin and principal is secure. While the various
protective elements are likely to change, such changes as can be visualized
are most unlikely to impair the fundamentally strong position of such issues.

Aa: Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known
as high grade bonds. They are rated lower than the best bonds because margins
of protection may not be as large as in Aaa securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risk appear somewhat larger than the Aaa
securities.

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

SECURITIES IN WHICH THE PORTFOLIO MAY INVEST WILL INCLUDE THOSE IN THE
FOLLOWING CATEGORIES:

Baa: Bonds which are rated Baa are considered as medium-grade obligations
(i.e., they are neither highly protected nor poorly secured). Interest
payments and principal security appear adequate for the present but certain
protective elements may be lacking or may be characteristically unreliable
over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.

Ba: Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well-assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.

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

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

Ca: Bonds which are rated Ca represent obligations which are speculative in a
high degree. Such issues are often in default or have other marked
shortcomings.

C: Bonds which are rated C are the lowest rated class of bonds, and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.

NOTE: Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa to B. The modifier 1 indicates that the company ranks
in the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and the modifier 3 indicates that the company ranks in the
lower end of its generic rating category.

                 DESCRIPTION OF S&P'S CORPORATE DEBT RATINGS:
INVESTMENT GRADE

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

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

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

SECURITIES IN WHICH THE PORTFOLIO MAY INVEST WILL INCLUDE THOSE IN THE
FOLLOWING CATEGORIES:

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

SPECULATIVE GRADE

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

BB: Debt rated BB has less near-term vulnerability to default than other
speculative issues. However, it faces major ongoing uncertainties or exposure
to adverse business, financial, or economic conditions which could lead to
inadequate capacity to meet timely interest and principal payments. The BB
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied BBB- rating.

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

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

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

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

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

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

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

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

NOTES: Debt which is unrated exposes the investor to risks with respect to
capacity to pay interest or repay principal which are similar to the risks of
lower-rated speculative obligations. The Portfolio is dependent on the
investment adviser's judgment, analysis and experience in the evaluation of
such debt.

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

                         EATON VANCE MUTUAL FUNDS TRUST

                            Amendment and Restatement
                                       of
                Establishment and Designation of Series of Shares
                    of Beneficial Interest, Without Par Value

                     (as amended and restated June 22, 1998)

     WHEREAS,  the Trustees of Eaton Vance Mutual Funds Trust,  a  Massachusetts
business trust (the "Trust"),  have  previously  designated  separate series (or
"Funds"); and

     WHEREAS, the Trustees now desire to add four additional series (i.e., Eaton
Vance Insured Tax-Managed Growth Fund, Eaton Vance Insured Tax-Managed  Emerging
Growth Fund, Eaton Vance Insured Tax-Managed International Growth Fund and Eaton
Vance Insured High Income Fund) and to further  redesignate  the series or Funds
pursuant  to  Section  5.1 of  Article V of the  Trust's  Amended  and  Restated
Declaration   of  Trust  dated  August  17,  1993  (as  further   Amended)  (the
"Declaration of Trust");

     NOW,  THEREFORE,  the  undersigned,  being at least a majority  of the duly
elected and qualified Trustees  presently in office of the Trust,  hereby divide
the shares of  beneficial  interest of the Trust into  sixteen  separate  series
("Funds"), each Fund to have the following special and relative rights:

     1. The Funds shall be designated as follows:

     Eaton Vance Government Obligations Fund
     Eaton Vance High Income Fund
     Eaton Vance Strategic Income Fund
     Eaton Vance Tax-Managed Growth Fund
     Eaton Vance Cash Management Fund
     Eaton Vance Liquid Assets Fund

     Eaton Vance Municipal Bond Fund
     Eaton Vance Short-Term Treasury Fund

     2. Each Fund shall be authorized to invest in cash, securities, instruments
and other  property as from time to time described in the Trust's then currently
effective  registration  statements  under  the  Securities  Act of 1933 and the
Investment  Company Act of 1940. Each share of beneficial  interest of each Fund

                                       1
<PAGE>

("share")  shall be  redeemable,  shall  be  entitled  to one vote (or  fraction
thereof in respect of afractional share) on matters on which shares of that Fund
shall be entitled to vote and shall represent a pro rata beneficial  interest in
the assets  allocated to that Fund, all as provided in the Declaration of Trust.
The proceeds of sales of shares of each Fund,  together with any income and gain
thereon,  less any diminution or expenses thereof,  shall irrevocably  belong to
such  Fund,  unless  otherwise  required  by law.  Each share of a Fund shall be
entitled  to  receive  its pro  rata  share  of net  assets  of that  Fund  upon
liquidation of that Fund.

     3. Shareholders of each Fund shall vote separately as a class to the extent
provided in Rule  18f-2,  as from time to time in effect,  under the  Investment
Company Act of 1940.

     4. The assets and  liabilities  of the Trust shall be  allocated  among the
above-referenced  Funds  as  set  forth  in  Section  5.5  of  Article  V of the
Declaration of Trust, except as provided below:

     (a) Costs  incurred by each Fund in connection  with its  organization  and
start-up,  including Federal and state  registration and qualification  fees and
expenses  of the  initial  public  offering  of such  Fund's  shares,  shall (if
applicable) be borne by such Fund.

     (b) Reimbursement  required under any expense limitation  applicable to the
Trust shall be  allocated  among those Funds whose  expense  ratios  exceed such
limitation on the basis of the relative expense ratios of such Funds.

     (c) The  liabilities,  expenses,  costs,  charges and reserves of the Trust
(other than the management and  investment  advisory fees or the  organizational
expenses paid by the Trust) which are not readily  identifiable  as belonging to
any particular  Fund shall be allocated among the Funds on an equitable basis as
determined by the Trustees.

     5. The Trustees  (including any successor Trustees) shall have the right at
any time and from time to time to  reallocate  assets and  expenses or to change
the designation of any Fund now or hereafter created, or to otherwise change the
special and relative  rights of any such Fund,  and to terminate any Fund or add
additional Funds as provided in the Declaration of Trust.

     6.  Any  Fund  may  merge  or  consolidate  with  any  other   corporation,
association,  trust or other  organization or may sell, lease or exchange all or
substantially all of its property,  including its good will, upon such terms and
conditions  and for such  consideration  when and as authorized by the Trustees;
and any such merger, consolidation,  sale, lease or exchange shall be deemed for
all purposes to have been accomplished under and pursuant to the statutes of the
Commonwealth  of  Massachusetts.  The  Trustees  may also at any  time  sell and
convert  into money all the assets of any Fund.  Upon making  provision  for the
payment of all outstanding obligations, taxes and other liabilities,  accrued or
contingent,  of such Fund, the Trustees shall distribute the remaining assets of
such Fund ratably among the holders of the outstanding  shares.  Upon completion
of the  distribution  of the  remaining  proceeds  or the  remaining  assets  as
provided in this paragraph 6, the Fund shall terminate and the Trustees shall be
discharged of any and all further  liabilities and duties hereunder with respect
to such Fund and the right,  title and  interest of all parties  with respect to
such Fund shall be canceled and discharged.

                                       2
<PAGE>

     7. The Declaration of Trust authorizes the Trustees to divide each Fund and
any other series of shares into two or more classes and to fix and determine the
relative  rights and preferences as between,  and all provisions  applicable to,
each of the different classes so established and designated by the Trustees. The
following  Funds  (Eaton Vance  Government  Obligations  Fund,  Eaton Vance High
Income Fund, Eaton Vance Strategic Income Fund, Eaton Vance  Tax-Managed  Growth
Fund, Eaton Vance Municipal Bond Fund, Eaton Vance  Tax-Managed  Emerging Growth
Fund and Eaton Vance Tax-Managed  International  Growth Fund) shall have classes
of shares  established  and  designated as Class A, Class B, Class C and Class I
shares,  and the Trustees may  designate  additional  classes in the future.  In
addition,  the  following  Funds (Eaton Vance Insured  Tax-Managed  Growth Fund,
Eaton Vance  Insured  Tax-Managed  Emerging  Growth  Fund,  Eaton Vance  Insured
Tax-Managed  International Growth Fund and Eaton Vance Insured High Income Fund)
shall have classes of shares  established  and designated as Class A and Class B
shares,  and the Trustees may designate  additional  classes in the future.  For
purposes of allocating  liabilities among classes, each class of that Fund shall
be treated in the same manner as a separate series.

                         EATON VANCE MUTUAL FUNDS TRUST

                            Amendment and Restatement
                                       of
                Establishment and Designation of Series of Shares
                    of Beneficial Interest, Without Par Value

                   (as amended and restated November 16, 1998)

     WHEREAS,  the Trustees of Eaton Vance Mutual Funds Trust,  a  Massachusetts
business trust (the "Trust"),  have  previously  designated  separate series (or
"Funds"); and

     WHEREAS,  the Trustees now desire to terminate one series (i.e. Eaton Vance
Short-Term Treasury Fund) effective December 30, 1998 pursuant to Section 5.1 of
Article V of the Trust's Amended and Restated  Declaration of Trust dated August
17, 1993 (as further Amended) (the "Declaration of Trust");

     NOW,  THEREFORE,  the  undersigned,  being at least a majority  of the duly
elected and qualified Trustees  presently in office of the Trust,  hereby divide
the shares of beneficial  interest of the Trust effective December 30, 1998 into
fifteen separate series  ("Funds"),  each Fund to have the following special and
relative rights:

     1. The Funds shall be designated as follows effective December 30, 1998:

     Eaton Vance Government Obligations Fund
     Eaton Vance High Income Fund
     Eaton Vance Strategic Income Fund
     Eaton Vance Tax-Managed Growth Fund
     Eaton Vance Cash Management Fund
     Eaton Vance Liquid Assets Fund
     Eaton Vance Money Market Fund
     Eaton Vance Municipal Bond Fund
     Eaton Vance Tax Free Reserves
     Eaton Vance Tax-Managed Emerging Growth Fund
     Eaton Vance Tax-Managed International Growth Fund
     Eaton Vance Insured Tax-Managed Growth Fund
     Eaton Vance Insured Tax-Managed Emerging Growth Fund
     Eaton Vance Insured Tax-Managed International Growth Fund
     Eaton Vance Insured High Income Fund

     2. Each Fund shall be authorized to invest in cash, securities, instruments
and other  property as from time to time described in the Trust's then currently
effective  registration  statements  under  the  Securities  Act of 1933 and the
Investment  Company Act of 1940. Each share of beneficial  interest of each Fund
("share")  shall be  redeemable,  shall  be  entitled  to one vote (or  fraction
thereof  in respect of a  fractional  share) on matters on which  shares of that
Fund  shall  be  entitled  to vote and  shall  represent  a pro rata  beneficial
<PAGE>

interest  in  the  assets  allocated  to  that  Fund,  all  as  provided  in the
Declaration  of Trust.  The  proceeds of sales of shares of each Fund,  together
with any income and gain thereon, less any diminution or expenses thereof, shall
irrevocably belong to such Fund, unless otherwise required by law. Each share of
a Fund shall be  entitled  to  receive  its pro rata share of net assets of that
Fund upon liquidation of that Fund.

     3. Shareholders of each Fund shall vote separately as a class to the extent
provided in Rule  18f-2,  as from time to time in effect,  under the  Investment
Company Act of 1940.

     4. The assets and  liabilities  of the Trust shall be  allocated  among the
above-referenced  Funds  as  set  forth  in  Section  5.5  of  Article  V of the
Declaration of Trust, except as provided below:

     (a) Costs  incurred by each Fund in connection  with its  organization  and
start-up,  including Federal and state  registration and qualification  fees and
expenses  of the  initial  public  offering  of such  Fund's  shares,  shall (if
applicable) be borne by such Fund.

     (b) Reimbursement  required under any expense limitation  applicable to the
Trust shall be  allocated  among those Funds whose  expense  ratios  exceed such
limitation on the basis of the relative expense ratios of such Funds.

     (c) The  liabilities,  expenses,  costs,  charges and reserves of the Trust
(other than the management and  investment  advisory fees or the  organizational
expenses paid by the Trust) which are not readily  identifiable  as belonging to
any particular  Fund shall be allocated among the Funds on an equitable basis as
determined by the Trustees.

     5. The Trustees  (including any successor Trustees) shall have the right at
any time and from time to time to  reallocate  assets and  expenses or to change
the designation of any Fund now or hereafter created, or to otherwise change the
special and relative  rights of any such Fund,  and to terminate any Fund or add
additional Funds as provided in the Declaration of Trust.

     6.  Any  Fund  may  merge  or  consolidate  with  any  other   corporation,
association,  trust or other  organization or may sell, lease or exchange all or
substantially all of its property,  including its good will, upon such terms and
conditions  and for such  consideration  when and as authorized by the Trustees;
and any such merger, consolidation,  sale, lease or exchange shall be deemed for
all purposes to have been accomplished under and pursuant to the statutes of the
Commonwealth  of  Massachusetts.  The  Trustees  may also at any  time  sell and
convert  into money all the assets of any Fund.  Upon making  provision  for the
payment of all outstanding obligations, taxes and other liabilities,  accrued or
contingent,  of such Fund, the Trustees shall distribute the remaining assets of
such Fund ratably among the holders of the outstanding  shares.  Upon completion
of the  distribution  of the  remaining  proceeds  or the  remaining  assets  as
provided in this paragraph 6, the Fund shall terminate and the Trustees shall be
discharged of any and all further  liabilities and duties hereunder with respect
to such Fund and the right,  title and  interest of all parties  with respect to
such Fund shall be canceled and discharged.

     7. The Declaration of Trust authorizes the Trustees to divide each Fund and
any other series of shares into two or more classes and to fix and determine the
relative  rights and preferences as between,  and all provisions  applicable to,
each of the different classes so established and designated by the Trustees. The
following  Funds  (Eaton Vance  Government  Obligations  Fund,  Eaton Vance High
Income Fund, Eaton Vance Strategic Income Fund, Eaton Vance  Tax-Managed  Growth
Fund, Eaton Vance Municipal Bond Fund, Eaton Vance  Tax-Managed  Emerging Growth
Fund and Eaton Vance Tax-Managed  International  Growth Fund) shall have classes
of shares  established  and  designated as Class A, Class B, Class C and Class I
shares,  and the Trustees may  designate  additional  classes in the future.

<PAGE>

In addition,  the following Funds (Eaton Vance Insured  Tax-Managed Growth Fund,
Eaton Vance  Insured  Tax-Managed  Emerging  Growth  Fund,  Eaton Vance  Insured
Tax-Managed  International Growth Fund and Eaton Vance Insured High Income Fund)
shall have classes of shares  established  and designated as Class A and Class B
shares,  and the Trustees may designate  additional  classes in the future.  For
purposes of allocating  liabilities among classes, each class of that Fund shall
be treated in the same manner as a separate series.

                                                               Exhibit (m)(3)(c)

                         EATON VANCE MUTUAL FUNDS TRUST

                              CLASS S SERVICE PLAN


     WHEREAS,  Eaton Vance Mutual Funds Trust (the "Trust")  engages in business
as an open-end management  investment company with series with multiple classes,
and is registered as such under the  Investment  Company Act of 1940, as amended
(the "Act");

     WHEREAS, on June 23, 1997 the Trust adopted a Multiple Class Plan on behalf
of its series and on February 22, 1999 the Trustees  amended the  Declaration of
Trust to establish five classes of shares  (including Class S shares) within the
Tax-Managed Growth Fund series ("TMG Fund");

     WHEREAS,  the Trust on behalf of TMG Fund  desires to adopt a Service  Plan
with respect to the Fund's Class S shares  pursuant to which the Fund intends to
pay service fees out of Class S assets as  contemplated  in subsections  (b) and
(d) of Rule 2830 of the Conduct Rules of the National  Association of Securities
Dealers, Inc. (the "NASD Rules");

     WHEREAS,  the  Trustees  of the  Trust  have  determined  that  there  is a
reasonable likelihood that adoption of this Service Plan will benefit the Trust,
TMG Fund and the holders of Class S shares of such Fund.

     NOW,  THEREFORE,  the Trust hereby adopts this Service Plan (the "Plan") on
behalf  of Class S  shares  of TMG  Fund  containing  the  following  terms  and
conditions:

     1. TMG Fund may make  payments  of  service  fees out of Class S assets  to
Eaton Vance  Distributors,  Inc.,  which may pay some or all of such  amounts to
broker-dealers or others providing shareholder  services.  The aggregate of such
payments  during  any fiscal  year of TMG Fund shall not exceed  .20% of average
daily net assets of Class S for such year. Appropriate adjustment of service fee
payments  shall be made whenever  necessary to ensure that no such payment shall
cause the  Class to  exceed  the  applicable  maximum  cap  imposed  thereon  by
subsection (d)(5) of Rule 2830 of the NASD Rules.

     2. This Plan shall not take effect until after it has been approved by both
a majority of (i) those Trustees of the Trust who are not  "interested  persons"
of the Trust (as  defined in the Act) and have no direct or  indirect  financial
interest in the  operations  of this Plan or any  agreements  related to it (the
"Rule 12b-1  Trustees"),  and (ii) all of the Trustees  then in office,  cast in
person at a meeting (or meetings) called for the purpose of voting on this Plan.

     3. Any  agreements  between  the Trust on behalf of TMG Fund and any person
relating  to this Plan  shall be in  writing  and shall  not take  effect  until
approved in the manner provided for Trustee approval of this Plan in Section 2.

     4. This Plan shall  continue in effect with  respect to each Class S for so
long as such  continuance  is  specifically  approved  at least  annually in the
manner provided for Trustee approval of this Plan in Section 2.
<PAGE>
     5. The  persons  authorized  to direct the  disposition  of monies  paid or
payable by the Trust pursuant to this Plan or any related agreement shall be the
President  or any Vice  President or the  Treasurer  of the Trust.  Such persons
shall  provide to the Trustees of the Trust and the Trustees  shall  review,  at
least  quarterly,  a written  report of the amounts so expended and the purposes
for which such expenditures were made.

     6. This Plan may be  terminated  as to TMG Fund with respect to its Class S
shares at any time by vote of a majority of the Rule 12b-1 Trustees.

     7. This Plan may not be amended to increase  the payments to be made by the
Class S shares of TMG Fund as  provided in Section 1 unless  such  amendment  is
approved  by a vote of at least a  majority  of the Class S  outstanding  voting
securities  of TMG Fund (as  defined  in the Act).  In  addition,  all  material
amendments to this Plan shall be approved in the manner  provided for in Section
2.

     8. While this Plan is in effect,  the selection and  nomination of the Rule
12b-1 Trustees shall be committed to the discretion of the Rule 12b-1 Trustees.

     9. The Trust shall preserve copies of this Plan and any related  agreements
made by the Trust and all  reports  made  pursuant to Section 5, for a period of
not less than six years  from the date of this  Plan,  the first two years in an
easily accessible place.

     10.  Consistent  with the  limitation of  shareholder,  officer and Trustee
liability  as set forth in the Trust's  Declaration  of Trust,  any  obligations
assumed by the Class S shares of TMG Fund pursuant to this Plan shall be limited
in all cases to the  assets of such  Class S shares  and no  person  shall  seek
satisfaction  thereof from the  shareholders of TMG Fund or officers or Trustees
of the Trust or any other class or series of the Trust.

     11.  When used in this Plan,  the term  "service  fees" shall have the same
meaning  as such  term has in  subsections  (b) and (d) of Rule 2830 of the NASD
Rules.

     12. If any  provision of this Plan shall be held or made invalid by a court
decision,  statute, rule or regulation of the Securities and Exchange Commission
or otherwise, the remainder of this Plan shall not be affected thereby.

     13. This Plan shall be effective upon the issuance of Class S shares.


                            Adopted February 22, 1999
