                                   THE TRUST
 
  The Fund is a series of Loomis Sayles Funds (the "Trust"). The Trust is a
diversified open-end management investment company organized as a
Massachusetts business trust on February 20, 1991. The Trust is authorized to
issue an unlimited number of full and fractional shares of beneficial interest
in multiple series. Shares are freely transferable and entitle shareholders to
receive dividends as determined by the Trust's board of trustees and to cast a
vote for each share held at shareholder meetings. The Trust does not generally
hold shareholder meetings and will do so only when required by law.
Shareholders may call meetings to consider removal of the Trust's trustees.
 
                      INVESTMENT OBJECTIVES AND POLICIES
 
  The Fund's investment objective is long-term growth of capital.
 
  The Fund seeks to achieve its objective by investing substantially all of its
assets in common stocks or their equivalent. Loomis Sayles seeks to build a
highly focused portfolio of approximately 20 stocks with a minimum market
capitalization of $1 billion. Loomis Sayles uses a bottom-up, fundamental
approach to select stocks for the Fund. In deciding whether to buy and sell
investments for the Fund, Loomis Sayles will consider a variety of factors such
as earnings growth, price/earnings ratio, cash flows and general financial
health. The Fund may invest any portion of its assets in securities of Canadian
issuers and up to 20% of its total assets in the securities of issuers
headquartered outside the United States or Canada. The Fund may also engage in
foreign currency hedging transactions, options and futures transactions,
securities lending and Rule 144A securities transactions. 

     For temporary defensive purposes, the Fund may invest any portion of its
assets in fixed income securities, cash and any other securities deemed
appropriate by Loomis Sayles. Except for the Fund's investment objective, and
any investment policies that are identified as "fundamental," all of the
investment policies of the Fund may be changed without a vote of Fund
shareholders.

     MORE INFORMATION ABOUT THE FUND'S INVESTMENTS AND RISK CONSIDERATIONS
 
Common Stocks and Other Equity Securities
 
  Common stocks and similar equity securities, such as warrants and
convertibles, are volatile and more risky than some other forms of investment.
The value of an investment in the Fund that invests in equity securities may
decrease. Equity securities of companies with relatively small market
capitalization may be more volatile than the securities of larger, more
established companies and than the broad equity market indexes. 

     Because the Fund generally will invest in a relatively small number of
stock, its value is likely to be more volatile than mutual funds that invest in
a larger number of stocks. for the same reason, the Fund is likely to be
adversely affected by a decline in the value of a particular holding to a
greater extent than mutual funds that have a greater number of holdings.

When-Issued Securities
 
  The Fund may purchase securities on a "when-issued" basis. This means that
the Fund may enter into a commitment to buy the security before the security
has been issued. The Fund's payment obligation and the interest rate on the
security are determined when the Fund enters into the commitment. The security
is typically delivered to the Fund 15 to 120 days later. No interest accrues
on the security between the time the Fund enters into the commitment and the
time the security is delivered. If the value of the security being purchased
falls between the time the Fund commits to buy it and the payment date, the
Fund may sustain a loss. The risk of this loss is in addition to the Fund's
risk of loss on the securities actually in its portfolio at the time. In
addition, when the Fund buys a security on a when-issued basis, it is subject
to the risk that market rates of interest will increase before the time the
security is delivered, with the result that the yield on the security
delivered to the Fund may be lower than the yield available on other
comparable securities at the time of delivery. If the Fund has outstanding
obligations to buy when-issued securities, it will maintain liquid assets in a
segregated account at its custodian bank in an amount sufficient to satisfy
these obligations.
 
Rule 144A Securities
 
  The Fund may invest in Rule 144A securities, which are privately offered
securities that can be resold only to certain qualified institutional buyers.
Rule 144A securities are treated as illiquid, unless Loomis Sayles has
determined, under guidelines established by the Trust's trustees, that the
particular issue of Rule 144A securities is liquid.
 
Foreign Securities
 
  The Fund may invest in securities of issuers organized or headquartered
outside the United States ("foreign securities"). The Fund may invest any
portion of its assets in securities of Canadian issuers, but will not purchase
foreign securities other than those of Canadian issuers if, as a result, the
Fund's holding of non-U.S. and non-Canadian securities would exceed 20% of the
Fund's total assets.

<PAGE>
 
  Although investing in foreign securities may increase the Fund's
diversification, foreign securities may present risks not associated with
investments in comparable securities of U.S. issuers. There may be less
information publicly available about a foreign corporate or governmental
issuer than about a U.S. issuer, and foreign corporate issuers are not
generally subject to accounting, auditing and financial reporting standards
and practices comparable to those in the United States. The securities of some
foreign issuers are less liquid and at times more volatile than securities of
comparable U.S. issuers. Foreign brokerage commissions and securities custody
costs are often higher than in the United States. With respect to certain
foreign countries, there is a possibility of governmental expropriation of
assets, confiscatory taxation, political or financial instability and
diplomatic developments that could affect the value of investments in those
countries. The Fund's receipt of interest on foreign government securities may
depend on the availability of tax or other revenues to satisfy the issuer's
obligations.
 
  The Fund's investments in foreign securities may include investments in
countries whose economies or securities markets are not highly developed.
Special considerations associated with these investments (in addition to the
considerations regarding foreign investments generally) may include, among
others, greater political uncertainties, an economy's dependence on revenues
from particular commodities or on international aid or development assistance,
currency transfer restrictions, highly limited numbers of potential buyers for
such securities and delays and disruptions in securities settlement
procedures.
 
  Since most foreign securities are denominated in foreign currencies or
traded primarily in securities markets in which settlements are made in
foreign currencies, the value of these investments and the net investment
income available for distribution to shareholders of the Fund investing in
these securities may be affected favorably or unfavorably by changes in
currency exchange rates, exchange control regulations or foreign withholding
taxes. Changes in the value relative to the U.S. dollar of a foreign currency
in which the Fund's holdings are denominated will result in a change in the
U.S. dollar value of the Fund's assets and the Fund's income available for
distribution.
 
  In addition, although part of the Fund's income may be received or realized
in foreign currencies, the Fund will be required to compute and distribute its
income in U.S. dollars. Therefore, if the value of a currency relative to the
U.S. dollar declines after the Fund's income has been earned in that currency,
translated into U.S. dollars and declared as a dividend, but before payment of
the dividend, the Fund could be required to liquidate portfolio securities to
pay the dividend. Similarly, if the value of a currency relative to the U.S.
dollar declines between the time the Fund accrues expenses in U.S. dollars and
the time such expenses are paid, the amount of such currency required to be
 
                                       6
<PAGE>
 
converted into U.S. dollars will be greater than the equivalent amount in such
currency of such expenses at the time they were incurred.
 
  In determining whether to invest assets of the Fund in securities of a
particular foreign issuer, Loomis Sayles will consider the likely effects of
foreign taxes on the net yield available to the Fund and its shareholders.
Compliance with foreign tax law may reduce the Fund's net income available for
distribution to shareholders.
 
Foreign Currency Hedging Transactions
 
  The Fund may engage in foreign currency exchange transactions in connection
with the purchase and sale of foreign securities to protect the value of
specific portfolio positions or in anticipation of changes in relative values
of currencies in which current or future Fund portfolio holdings are
denominated or quoted. For example, to protect against a change in the foreign
currency exchange rate between the date on which the Fund contracts to
purchase or sell a security and the settlement date for the purchase or sale,
or to "lock in" the equivalent of a dividend or interest payment in another
currency, the Fund might purchase or sell a foreign currency on a spot (that
is, cash) basis at the prevailing spot rate. If conditions warrant, the Fund
may also enter into private contracts to purchase or sell foreign currencies
at a future date ("forward contracts"). The Fund might also purchase exchange-
listed and over-the-counter call and put options on foreign currencies. Over-
the-counter currency options are generally less liquid than exchange-listed
options and will be treated as illiquid assets. The Fund may not be able to
dispose of over-the-counter options readily.
 
  Foreign currency transactions involve costs and may result in losses.
 
Options and Futures Transactions
 
  The Fund may buy, sell or write options on securities, securities indexes,
currencies or futures contracts. The Fund may engage in these transactions
either for the purpose of enhancing investment return or to hedge against
changes in the value of other assets that the Fund owns or intends to acquire.
Options and futures fall into the broad category of financial instruments
known as "derivatives" and involve special risks. Use of options or futures
for other than hedging purposes may be considered a speculative activity,
involving greater risks than are involved in hedging.
 
  Options can generally be classified as either "call" or "put" options. There
are two parties to a typical options transaction: the "writer" and the
"buyer." A call option gives the buyer the right to buy a security or other
asset (such as an amount of currency or a futures contract) from, and a put
option gives the buyer the right to sell a security or other asset to, the
option writer at a specified price, on or before a specified date. The buyer
of an option pays a
 
                                       7
<PAGE>
 
premium when purchasing the option, which reduces the return on the underlying
security or other asset if the option is exercised, and results in a loss if
the option expires unexercised. The writer of an option receives a premium
from writing an option, which may increase its return if the option expires or
is closed out at a profit. If the Fund as the writer of an option is unable to
close out an unexpired option, it must continue to hold the underlying
security or other asset until the option expires, to "cover" its obligation
under the option.
 
  A futures contract creates an obligation by the seller to deliver and the
buyer to take delivery of the type of instrument or cash at the time and in
the amount specified in the contract. Although many futures contracts call for
the delivery (or acceptance) of the specified instrument, futures are usually
closed out before the settlement date through the purchase (or sale) of a
comparable contract. If the price of the sale of the futures contract by the
Fund exceeds (or is less than) the price of the offsetting purchase, the Fund
will realize a gain (or loss). The value of options purchased or written by
the Fund and futures contracts held by the Fund may fluctuate based on a
variety of market and economic factors. In some cases, the fluctuations may
offset (or be offset by) changes in the value of securities held in the Fund's
portfolio. All transactions in options and futures involve the possible risk
of loss to the Fund of all or a significant part of the value of its
investment. In some cases, the risk of loss may exceed the amount of the
Fund's investment. When the Fund writes a call option or sells a futures
contract without holding the underlying securities, currencies or futures
contracts, its potential loss is unlimited. The Fund will be required,
however, to set aside with its custodian bank liquid assets in amounts
sufficient at all times to satisfy its obligations under options and futures
contracts.
 
  The successful use of options and futures usually will depend on Loomis
Sayles' ability to forecast stock market, currency or other financial market
movements correctly. The Fund's ability to hedge against adverse changes in
the value of securities held in its portfolio through options and futures also
depends on the degree of correlation between the changes in the value of
futures or options positions and changes in the values of the portfolio
securities. The successful use of futures and exchange traded options also
depends on the availability of a liquid secondary market to enable the Fund to
close its positions on a timely basis. There can be no assurance that such a
market will exist at any particular time. In the case of options that are not
traded on an exchange ("over-the-counter" options), the Fund is at risk that
the other party to the transaction will default on its obligations, or will
not permit the Fund to terminate the transaction before its scheduled
maturity. As a result of these characteristics, the Fund will treat most over-
the-counter options (and the assets it segregates to cover its obligations
thereunder) as illiquid.
 
  The options and futures market of foreign countries are small compared to
those of the United States and consequently are characterized in most cases by
 
                                       8
<PAGE>
 
less liquidity than are the U.S. markets. In addition, foreign markets may be
subject to less detailed reporting requirements and regulatory controls than
U.S. markets. Furthermore, investments in options in foreign markets are
subject to many of the same risks as other foreign investments. See "Foreign
Securities" above.
 
Repurchase Agreements
 
  The Fund may invest in repurchase agreements. In repurchase agreements, the
Fund buys securities from a seller, usually a bank or brokerage firm, with the
understanding that the seller will repurchase the securities at a higher price
at a later date. Such transactions afford an opportunity for the Fund to earn
a return on available cash at minimal market risk, although the Fund may be
subject to various delays and risks of loss if the seller is unable to meet
its obligations to repurchase.
 
Securities Lending
 
  The Fund may lend its portfolio securities to broker-dealers or other
parties under contracts calling for the deposit by the borrower with the
Fund's custodian of cash collateral equal to at least the market value of the
securities loaned, marked to market on a daily basis. The Fund will continue
to benefit from interest or dividends on the securities loaned and will also
receive interest through investment of the cash collateral in short-term
liquid investments. No loans will be made if, as a result, the aggregate
amount of such loans outstanding at any time would exceed 33 1/3% of the
Fund's total assets (taken at current value). Any voting rights, or rights to
consent, relating to securities loaned pass to the borrower. However, if a
material event affecting the investment occurs, such loans will be called so
that the securities may be voted by the Fund. The Fund pays various fees in
connection with such loans, including shipping fees and reasonable custodial
or placement fees.
 
  Securities loans must be fully collateralized at all times, but involve some
credit risk to the Fund if the borrower defaults on its obligation and the
Fund is delayed or prevented from recovering the collateral.
 
Year 2000
 
  Many computer software systems in use today cannot properly process date-
related information from and after January 1, 2000. Should any of the computer
systems employed by the Fund's major service providers fail to process this
type of information properly, that could have a negative impact on the Fund's
operations and the services that are provided to the Fund's shareholders.
Loomis Sayles and the Distributor each have advised the Fund that they are
reviewing all of their computer systems with the goal of modifying or
 
                                       9
<PAGE>
 
replacing such systems prior to January 1, 2000, to the extent necessary to
foreclose any such negative impact. In addition, Loomis Sayles has been
advised by the Fund's custodian that it also is reviewing its systems with the
same goal. As of the date of this prospectus, the Fund and Loomis Sayles have
no reason to believe that these goals will not be achieved. Similarly, the
values of certain of the portfolio securities held by the Fund may be
adversely affected by the inability of the securities' issuers or of third
parties to process this type of information properly.
 
                         THE FUND'S INVESTMENT ADVISER
 
  The Fund's investment adviser is Loomis Sayles, One Financial Center,
Boston, Massachusetts 02111. Founded in 1926, Loomis Sayles is one of the
country's oldest and largest investment firms. The general partner of Loomis
Sayles is a special purpose corporation that is an indirect wholly-owned
subsidiary of Nvest Companies, L.P. ("Nvest Companies"). Nvest Companies'
managing general partner, Nvest Corporation, is a direct wholly-owned
subsidiary of Metropolitan Life Insurance Company ("Met Life"), a mutual life
insurance company. Nvest Companies' advising general partner, Nvest, L.P., is
a publicly traded company listed on the New York Stock Exchange. Nvest
Corporation is the sole general partner of Nvest L.P.
 
  In addition to selecting and reviewing the Fund's investments, Loomis Sayles
provides executive and other personnel for the management of the Fund. The
Trust's board of trustees supervises Loomis Sayles' conduct of the affairs of
the Funds.
 
  Philip J. Schettewi and Roderick H. Dillon, Vice Presidents of the Trust and
Loomis Sayles, have served as the portfolio managers of the Fund since its
commencement of investment operations in 1999. Mr. Schettewi has been employed
by Loomis Sayles since 1991. Prior to joining Loomis Sayles in 1997, Mr.
Dillon was President of Dillon Capital Management, from 1993. Dillon Capital
Management was acquired by Loomis Sayles in 1997.
 
                                 FUND EXPENSES
 
  The Fund pays Loomis Sayles a monthly investment advisory fee of .50% of the
Fund's average daily net assets. In addition to the investment advisory fee,
the Fund pays all expenses not expressly assumed by Loomis Sayles, including
taxes, brokerage commissions, fees and expenses of registering or qualifying
the Fund's shares under federal and state securities laws, fees of the Fund's
custodian, transfer agent, independent accountants and legal counsel, expenses
of shareholders' and trustees' meetings, 12b-1 fees (in the case of the
 
                                      10
<PAGE>
 
Retail Class shares), expenses of preparing, printing and mailing prospectuses
to existing shareholders and fees of trustees who are not directors, officers
or employees of Loomis Sayles or its affiliated companies.
 
  The Fund's Retail Class shares have adopted a Distribution Plan pursuant to
Rule 12b-1 under the Investment Company Act of 1940. Under the Plan, the
Retail Class shares of the Fund pay the Distributor, a subsidiary of Loomis
Sayles, a monthly distribution fee at an annual rate not to exceed 0.25% of
the Fund's average daily net assets attributable to the Retail Class shares.
The Distributor may pay all or any portion of the distribution fee to
securities dealers or other organizations (including, but not limited to, any
affiliate of the Distributor) as commissions, asset-based sales charges or
other compensation with respect to the sale of Retail Class shares of the
Fund, or for providing personal services to investors in Retail Class shares
of the Fund and/or the maintenance of accounts, and may retain all or any
portion of the distribution fee as compensation for the Distributor's services
as principal underwriter of the Retail Class shares of the Fund.
 
  Loomis Sayles has voluntarily agreed, for an indefinite period, to reduce
its advisory fees and/or bear other Fund expenses to the extent necessary to
limit total annual operating expenses to 1.00% and 1.25% of the Fund's average
daily net assets attributable to Institutional Class shares and Retail Class
shares, respectively. Loomis Sayles may change or terminate this voluntary
arrangement at any time, but the Fund's Prospectus would be supplemented to
describe the change.
 
  Loomis Sayles may pay certain broker-dealers and financial intermediaries
whose customers own shares of the Fund a continuing fee in an amount up to
 .25% annually of the value of Fund shares held for those customers' accounts.
These fees are paid by Loomis Sayles out of its own assets and are not
assessed against the Fund.
 
                            PORTFOLIO TRANSACTIONS
 
  Portfolio turnover considerations will not limit Loomis Sayles' investment
discretion in managing the Fund's assets. The Fund anticipates that its
portfolio turnover rate will vary significantly from time to time depending on
the volatility of economic and market conditions. High portfolio turnover may
involve higher transaction costs and higher levels of taxable gains.
 
                            HOW TO PURCHASE SHARES
 
  An investor may make an initial purchase of shares of the Fund by submitting
a completed application form and payment to:
 
                                      11

      Boston Financial Data Services
      P.O. Box 8314
      Boston, Massachusetts 02266-8314
      Attn: Loomis Sayles Funds
 
  The minimum initial investment for the Institutional Class of shares of the
Fund is $1 million. A $2,500 minimum investment applies to the current and
retired trustees of the Trust, investment advisory clients of Loomis Sayles
(and their directors, officers and employees), and current and retired
employees of Loomis Sayles and the parents, spouses and children of the
foregoing. The minimum initial investment for the Retail Class of shares is
$25,000. This minimum initial investment for Retail Class shares does not
apply to purchases through certain financial intermediaries, including, but
not limited to, certain financial advisers, broker dealers, 401(k) alliances,
wrap programs, "no transaction fee" programs, bank trust departments,
financial consultants and insurance companies. The minimum investment for
Institutional Class shares and Retail Class shares may be waived in whole or
in part by Loomis Sayles in its sole discretion. Subsequent investments in
either class of shares must be at least $50.
 
  Shares of the Fund may be purchased by (i) cash, (ii) exchanging
Institutional Class shares of any other fund that is a series of the Trust for
Institutional Class shares of the Fund or exchanging Retail Class shares of
any other fund that is a series of the Trust for Retail Class shares of the
Fund, provided the value of the shares exchanged meets the investment minimum
of the Class of shares of the Fund into which the exchange is made,
(iii) exchanging securities on deposit with a custodian acceptable to Loomis
Sayles or (iv) a combination of such securities and cash. Loomis Sayles will
not approve the acceptance of securities in exchange for shares of the Fund
unless (1) Loomis Sayles, in its sole discretion, believes the securities are
appropriate investments for the Fund; (2) the investor represents and agrees
that all securities offered to the Fund can be resold by the Fund without
restriction under the Securities Act of 1933, as amended (the "Securities
Act") or otherwise; and (3) the securities are eligible to be acquired under
the Fund's investment policies and restrictions. No investor owning 5% or more
of the Fund's shares may purchase additional shares of the Fund by exchange of
securities.
 
  In all cases Loomis Sayles reserves the right to reject any securities that
are proposed for exchange. Securities accepted by Loomis Sayles in exchange
for Fund shares will be valued in the same manner as the Fund's assets as
described below as of the time of the Fund's next determination of net asset
value after such acceptance. All dividends and subscription or other rights
that are reflected in the market price of accepted securities at the time of
valuation become the property of the Fund and must be delivered to the Fund
upon receipt
 
                                      12
<PAGE>
 
by the investor from the issuer. A gain or loss for federal income tax
purposes would be realized upon the exchange by an investor that is subject to
federal income taxation, depending upon the investor's basis in the securities
tendered. An investor who wishes to purchase shares by exchanging securities
should obtain instructions by calling 800-633-3330, option 5.
 
  All purchases made by check should be in U.S. dollars and made payable to
State Street Bank and Trust Company. Third party checks will not be accepted.
When purchases are made by check or periodic account investment, redemption
will not be allowed until the investment being redeemed has been in the
account for 15 calendar days.
 
  Upon acceptance of an investor's order, BFDS opens an account, applies the
payment to the purchase of full and fractional Fund shares and mails a
statement of the account to the investor's address of record to confirm the
transaction.
 
  After an account has been established, an investor may send subsequent
investments at any time directly to BFDS at the above address. The remittance
must be accompanied by either the account identification slip detached from a
statement of account or a note containing sufficient information to identify
the account, i.e., the Fund name and the investor's account number or name and
social security number.
 
  Subsequent investments can also be made by federal funds wire. Investors
should instruct their banks to wire federal funds to State Street Bank and
Trust Company, ABA #011000028. The text of the wire should read as follows:
"$    amount, STATE STREET BOS ATTN Mutual Funds. Credit Fund (Select
Opportunities Fund and Class, Institutional or Retail), DDA #9904-622-9,
Account Name, Account Number." A bank may charge a fee for transmitting funds
by wire.
 
  The Fund and the Distributor reserve the right to reject any purchase order,
including orders in connection with exchanges, for any reason that the Fund or
the Distributor in its sole discretion deems appropriate. Although the Fund
does not presently anticipate that it will do so, the Fund reserves the right
to suspend or change the terms of the offering of its shares.
 
  The price an investor pays will be the per share net asset value next
calculated after a proper investment order is received by the Trust's transfer
or other agent or subagent. Shares of the Fund are sold with no sales charge.
The net asset value of the Fund's shares is calculated once daily, as of the
close of regular trading on the New York Stock Exchange on each day the
Exchange is open for trading, by dividing the Fund's net assets by the number
of shares
 
                                      13
<PAGE>
 
outstanding. Portfolio securities are valued at their market value as more
fully described in the Statement of Additional Information.
 
  The Distributor may accept telephone orders from broker-dealers who have
been previously approved by the Distributor. It is the responsibility of such
broker-dealers to forward purchase or redemption orders to the Distributor
promptly. Although there is no sales charge imposed by the Fund or the
Distributor, broker-dealers may charge the investor a transaction-based fee or
other fee for their services at either the time of purchase or the time of
redemption. Such charges may vary among broker-dealers but in all cases will
be retained by the broker-dealer and not remitted to the Fund.
 
                             SHAREHOLDER SERVICES
 
  The Fund offers the following shareholder services, which are more fully
described in the Statement of Additional Information. Explanations and forms
are available from BFDS. Telephone redemption and exchange privileges will be
established automatically when an investor opens an account unless an investor
elects on the application to decline telephone privileges. Other privileges
must be specifically elected. A signature guarantee will be required to
establish a privilege after an account is opened.
 
  Free Exchange Privilege. Institutional Class shares and Retail Class shares
of the Fund may be exchanged for Institutional Class shares or Retail Class
shares, respectively, of any other fund that is a series of Loomis Sayles
Funds and that offers Institutional Class shares or Retail Class shares,
respectively, or for shares of certain money market funds advised by New
England Funds Management, L.P., an affiliate of Loomis Sayles, provided the
value of the shares exchanged meets the investment minimum of the Class of
shares of that Fund and, in the case of Loomis Sayles High Yield Fund-
Institutional Class, Loomis Sayles Municipal Fund-Institutional Class and
Loomis Sayles U.S. Government Securities Fund-Institutional Class, Loomis
Sayles has approved the exchange of shares. Exchanges may be made by written
instructions or by telephone, unless an investor elected on the application to
decline telephone exchange privileges. The exchange privilege should not be
viewed as a means of taking advantage of short-term swings in the market, and
the Fund reserves the right to terminate or limit the privilege of any
shareholder who makes more than four exchanges in any calendar year. The Fund
may terminate or change the terms of the exchange privilege at any time upon
60 days' notice to shareholders. An exchange is a taxable event for federal
income tax purposes in which a gain or loss would be realized by an investor
that is subject to federal income taxation.
 
                                      14
<PAGE>
 
  Retirement Plans. The Fund's shares may be purchased by all types of tax-
deferred retirement plans. Loomis Sayles makes available retirement plan forms
for IRAs.
 
  Systematic Withdrawal Plan. If the value of an account is at least $25,000,
an investor may have periodic cash withdrawals automatically paid to the
investor or any person designated by the investor.
 
  Automatic Investment Plan. Voluntary monthly investments of at least $50 may
be made automatically by pre-authorized withdrawals from an investor's
checking account.
 
                             HOW TO REDEEM SHARES
 
  An investor can redeem shares by sending a written request to Boston
Financial Data Services, Inc., P.O. Box 8314, Boston, Massachusetts 02266. As
described below, an investor may also redeem shares by calling BFDS at
800-626-9390. Proceeds resulting from a written or telephone redemption
request can be wired to an investor's bank account or sent by check in the
name of the registered owners to their record address.
 
  The written request must include the name of the Fund, the account number,
the exact name(s) in which the shares are registered, and the number of shares
or the dollar amount to be redeemed. All owners of the shares must sign the
request in the exact names in which the shares are registered (the exact names
appear on an investor's confirmation statement) and should indicate any
special capacity in which an owner is signing (such as trustee or custodian or
on behalf of a partnership, corporation or other entity). Investors requesting
that redemption proceeds be wired to their bank accounts must provide specific
wire instructions.
 
  If (1) an investor is redeeming shares worth more than $50,000, (2) an
investor is requesting that the proceeds check be made out to someone other
than the registered owners or be sent to an address other than the record
address, (3) the account registration has changed within the last 30 days or
(4) an investor is instructing us to wire the proceeds to a bank account not
designated on the application, the investor must have his or her signature
guaranteed by an eligible guarantor. This requirement may be waived by Loomis
Sayles in its sole discretion. Eligible guarantors include commercial banks,
trust companies, savings associations, credit unions and brokerage firms that
are members of domestic securities exchanges. Before submitting the redemption
request, an investor should verify with the guarantor institution that it is
an eligible guarantor. Signature guarantees by notaries public are not
acceptable.
 
 
                                      15
<PAGE>
 
  When an investor telephones a redemption request, the proceeds are wired to
the bank account previously chosen by the investor. A wire fee (currently $5)
will be deducted from the proceeds. A telephonic redemption request must be
received by BFDS prior to the close of regular trading on the New York Stock
Exchange. If an investor telephones a request to BFDS after the Exchange
closes or on a day when the Exchange is not open for business, BFDS cannot
accept the request and a new one will be necessary.
 
  If an investor decides to change the bank account to which proceeds are to
be wired, the investor must send in this change in writing with a signature
guarantee. Telephonic redemptions may be made only if the investor's bank is a
member of the Federal Reserve System or has a correspondent bank that is a
member of the System. Unless an investor indicates otherwise on the account
application, BFDS will be authorized to act upon redemption and exchange
instructions received by telephone from the investor or any person claiming to
act as the investor's representative who can provide BFDS with the investor's
account registration and address as it appears on the records of State Street
Bank. BFDS will employ these or other reasonable procedures to confirm that
instructions communicated by telephone are genuine. The Fund, State Street
Bank, BFDS, the Distributor and Loomis Sayles will not be liable for any
losses due to unauthorized or fraudulent instructions if these or other
reasonable procedures are followed. For more information on telephone
redemptions, consult BFDS. In times of heavy market activity, an investor who
encounters difficulty in placing a redemption or exchange order by telephone
may wish to place the order by mail as described above.
 
  The redemption price will be the net asset value per share next determined
after the redemption request and any necessary special documentation are
received by BFDS in proper form.
 
  Proceeds resulting from a written redemption request will normally be mailed
to an investor within seven days after receipt of the investor's request in
good order. Telephonic redemption proceeds will normally be wired to an
investor's bank on the first business day following receipt of a proper
redemption request. If an investor purchased shares by check and the check was
deposited less than 15 days prior to the redemption request, the Fund may
withhold redemption proceeds until the check has cleared.
 
  The Fund may suspend the right of redemption and may postpone payment for
more than seven days when the New York Stock Exchange is closed for other than
weekends or holidays, or if permitted by the rules of the SEC when trading on
the Exchange is restricted or during an emergency that makes it impracticable
for the Fund to dispose of its securities or to determine fairly the value of
its net assets, or during any other period permitted by the SEC for the
protection of investors.

                    CALCULATION OF PERFORMANCE INFORMATION
 
  "Total return" for the one-, five- and ten-year periods (or for the life of
a class, if shorter) through the most recent calendar quarter represents the
average annual compounded rate of return on an investment of $1,000 in the
Fund. Total return may also be presented for other periods.
 
                DIVIDENDS, CAPITAL GAIN DISTRIBUTIONS AND TAXES
 
  The Fund declares and pays net investment income to shareholders as
dividends annually. The Fund also distributes all of its net capital gains
realized from the sale of portfolio securities. Any capital gain distributions
are normally made annually, but may, to the extent permitted by law, be made
more frequently as deemed advisable by the trustees of the Trust. The Trust's
trustees may change the frequency with which the Fund declares or pays
dividends.
 
  Dividends and capital gain distributions will automatically be reinvested in
additional shares of the Fund unless an investor has elected to receive cash.
The Fund intends to qualify as a regulated investment company under the
Internal Revenue Code of 1986, as amended. As such, so long as the Fund
distributes substantially all its net investment income and net capital gains
to its shareholders, the Fund itself does not pay any federal income tax to
the extent such income and gains are so distributed.
 
  An investor's income dividends and short-term capital gain distributions
(that is, net gains from securities held for not more than a year) are taxable
as ordinary income whether distributed in cash or additional shares.
Distributions designated by the Fund as deriving from net gains on securities
held for more than one year (i.e., long-term capital gains) will be taxable as
such (generally at a 20% rate for noncorporate shareholders) whether
distributed in cash or additional shares and regardless of how long an
investor has owned shares of the Fund.
 
  A dividend or distribution made shortly after the purchase of shares of the
Fund by a shareholder, although in effect a return of capital to that
particular shareholder, would be taxable to him or her as described above. If
a shareholder held shares six months or less and during that period received a
distribution of net long-term capital gains, any loss realized on the sale of
such shares during such six-month period would be a long-term capital loss to
the extent of such distribution.
 
  The Fund is required to withhold 31% of any redemption proceeds (including
the value of shares exchanged) and all income dividends and capital gain
distributions it pays to an investor (1) if an investor does not provide a
correct, certified taxpayer identification number, (2) if the Fund is notified
that an investor has underreported income in the past, or (3) if an investor
fails to certify to the Fund that the investor is not subject to such
withholding.
 
                                      17
<PAGE>
 
  Certain designated dividends from the Fund are expected to be eligible for
the dividends-received deduction for corporate shareholders that meet a
holding period requirement.
 
  State Street Bank will send each investor and the Internal Revenue Service
an annual statement detailing federal tax information, including information
about dividends and distributions paid to the investor during the preceding
year. Be sure to keep this statement as a permanent record. A fee may be
charged for any duplicate information that an investor requests.
 
NOTE:    The foregoing summarizes certain tax consequences of investing in the
         Fund. Before investing, an investor should consult his or her own tax
         advisor for more information concerning the federal, foreign, state
         and local tax consequences of investing in, redeeming or exchanging
         Fund shares.

               INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS
 
  The investment objective and policies of the Loomis Sayles Select
Opportunities Fund of Loomis Sayles Funds (the "Trust"), are summarized in the
Prospectus under "Investment Objectives and Policies" and "More Information
About the Fund's Investments and Risk Considerations." The investment policies
of the Fund set forth in the Prospectus and in this Statement of Additional
Information may be changed by the Fund's adviser ("Loomis Sayles"), subject to
review and approval by the Trust's board of trustees, without shareholder
approval except that the investment objective of the Fund as set forth in the
Prospectus and the Fund policies explicitly identified as "fundamental" may
not be changed without the approval of the holders of a majority of the
outstanding shares of the Fund (which in the Prospectus and this Statement of
Additional Information means the lesser of (i) 67% of the shares of that Fund
represented at a meeting at which 50% of the outstanding shares are
represented or (ii) more than 50% of the outstanding shares). Except in the
case of the 15% limitation on illiquid securities, the percentage limitations
set forth below and in the Prospectus will apply at the time a security is
purchased and will not be considered violated unless an excess or deficiency
occurs or exists immediately after and as a result of such purchase.
 
  In addition to its investment objective and policies set forth in the
Prospectus, the following investment restrictions are policies of the Fund
(and those marked with an asterisk are fundamental policies of the Fund):
 
The Fund will not:
 
    (1) Invest in companies for the purpose of exercising control or
  management.
 
    *(2) Act as underwriter, except to the extent that, in connection with
  the disposition of portfolio securities, it may be deemed to be an
  underwriter under certain federal securities laws.
 
    *(3) Invest in oil, gas or other mineral leases, rights or royalty
  contracts or in real estate, commodities or commodity contracts. (This
  restriction does not prevent the Fund from engaging in transactions in
  futures contracts relating to securities indexes, interest rates or
  financial instruments or options, or from investing in issuers that invest
  or deal in the foregoing types of assets or from purchasing securities that
  are secured by real estate.)
 
    *(4) Make loans, except that the Fund may lend its portfolio securities
  to the extent permitted under the Investment Company Act of 1940 (the "1940
  Act"). (For purposes of this investment restriction, neither (i) entering
  into repurchase agreements nor (ii) purchasing bonds, debentures,
  commercial paper, corporate notes and similar evidences of indebtedness,
  which are a part of an issue to the public, is considered the making of a
  loan.)
 
    (5) With respect to 75% of its total assets, purchase any security (other
  than a U.S. Government Security) if, as a result, more than 5% of the
  Fund's total assets (taken at current value) would then be invested in
  securities of a single issuer.
 
    (6) With respect to 75% of its total assets, acquire more than 10% of the
  outstanding voting securities of an issuer.
 
    (7) Pledge, mortgage, hypothecate or otherwise encumber any of its
  assets, except that the Fund may pledge assets having a value not exceeding
  10% of its total assets to secure borrowings permitted by restriction (9)
  below. (For the purpose of this restriction, collateral arrangements with
  respect to options, futures contracts and options on futures contracts and
  with respect to initial and variation margin are not deemed to be a pledge
  or other encumbrance of assets.)
 
    *(8) Purchase any security (other than U.S. Government Securities) if, as
  a result, more than 25% of the Fund's total assets (taken at current value)
  would be invested in any one industry (in the utilities category, gas,
  electric, water and telephone companies will be considered as being in
  separate industries.)
 
    *(9) Borrow money in excess of 10% of its total assets (taken at cost) or
  5% of its total assets (taken at current value), whichever is lower, nor
  borrow any money except as a temporary measure for extraordinary or
  emergency purposes.
 
 
                                       3
<PAGE>
 
    (10) Purchase securities on margin (except such short term credits as are
  necessary for clearance of transactions); or make short sales (except
  where, by virtue of ownership of other securities, it has the right to
  obtain, without payment of additional consideration, securities equivalent
  in kind and amount to those sold).
 
    (11) Participate on a joint or joint and several basis in any trading
  account in securities. (The "bunching" of orders for the purchase or sale
  of portfolio securities with Loomis Sayles or accounts under its management
  to reduce brokerage commissions, to average prices among them or to
  facilitate such transactions is not considered a trading account in
  securities for purposes of this restriction.)
 
    (12) Purchase any illiquid security, including any security that is not
  readily marketable, if, as a result, more than 15% of the Fund's net assets
  (based on current value) would then be invested in such securities.
 
    (13) Write or purchase puts, calls or combinations of both except that
  the Fund may (1) acquire warrants or rights to subscribe to securities of
  companies issuing such warrants or rights, or of parents or subsidiaries of
  such companies, (2) purchase and sell put and call options on securities
  and (3) write, purchase and sell put and call options on currencies and may
  enter into currency forward contracts.
    *(14) Issue senior securities. (For the purpose of this restriction none
  of the following is deemed to be a senior security: any pledge or other
  encumbrance of assets permitted by restriction (7) above; any borrowing
  permitted by restriction (9) above; any collateral arrangements with
  respect to options, futures contracts and options on futures contracts and
  with respect to initial and variation margin; and the purchase or sale of
  options, forward contracts, futures contracts or options on futures
  contracts.)
 
  Although the Fund has no current intention of investing in repurchase
agreements, it intends, based on the views of the staff of the Securities and
Exchange Commission (the "SEC"), to restrict its investments in repurchase
agreements maturing in more than seven days, together with other investments
in illiquid securities, to the percentage permitted by restriction (12) above.
 
U.S. Government Securities
 
  U.S. Government Securities include direct obligations of the U.S. Treasury,
as well as securities issued or guaranteed by U.S. Government agencies,
authorities and instrumentalities, including, among others, the Government
National Mortgage Association, the Federal Home Loan Mortgage Corporation, the
Federal National Mortgage Association, the Federal Housing Administration, the
Resolution Funding Corporation, the Federal Farm Credit Banks, the Federal
Home Loan Bank, the Tennessee Valley Authority, the Student Loan Marketing
Association and the Small Business Administration. More detailed information
about some of these categories of U.S. Government Securities follows.
 
  U.S. Treasury Bills--Direct obligations of the United States Treasury which
are issued in maturities of one year or less. No interest is paid on Treasury
bills; instead, they are issued at a discount and repaid at full face value
when they mature. They are backed by the full faith and credit of the United
States Government.
 
  U.S. Treasury Notes and Bonds--Direct obligations of the United States
Treasury issued in maturities that vary between one and forty years, with
interest normally payable every six months. They are backed by the full faith
and credit of the United States Government.
 
  "Ginnie Maes"--Debt securities issued by a mortgage banker or other
mortgagee which represent an interest in a pool of mortgages insured by the
Federal Housing Administration or the Farmer's Home Administration or
guaranteed by the Veterans Administration. The Government National Mortgage
Association ("GNMA") guarantees the timely payment of principal and interest
when such payments are due, whether or not these amounts are collected by the
issuer of these certificates on the underlying mortgages. An assistant
attorney general of the United States has rendered an opinion that the
guarantee by GNMA is a general obligation of the United States backed by its
full faith and credit. Mortgages included in single family or multi-family
residential mortgage pools backing an issue of Ginnie Maes have a maximum
maturity of up to 30 years. Scheduled payments of principal and interest are
made to the registered holders of Ginnie Maes (such as the
 
                                       4
<PAGE>
 
Fund) each month. Unscheduled prepayments may be made by homeowners, or as a
result of a default. Prepayments are passed through to the registered holder
of Ginnie Maes along with regular monthly payments of principal and interest.
 
  "Fannie Maes"--Fannie Mae is a government-sponsored corporation owned
entirely by private stockholders that purchases residential mortgages from a
list of approved seller/servicers. Fannie Maes are pass-through securities
issued by Fannie Mae that are guaranteed as to timely payment of principal and
interest by Fannie Mae but are not backed by the full faith and credit of the
United States Government.
 
  "Freddie Macs"--The Federal Home Loan Mortgage Corporation ("FHLMC") is a
corporate instrumentality of the United States Government. Freddie Macs are
participation certificates issued by FHLMC that represent an interest in
residential mortgages from FHLMC's National Portfolio. FHLMC guarantees the
timely payment of interest and ultimate collection of principal, but Freddie
Macs are not backed by the full faith and credit of the United States
Government.
 
  As described in the Prospectus, U.S. Government Securities generally do not
involve the same credit risks associated with investments in other types of
fixed-income securities, although, as a result, the yields available from U.S.
Government Securities are generally lower than the yields available from
corporate fixed-income securities. Like other fixed-income securities,
however, the values of U.S. Government Securities change as interest rates
fluctuate. Fluctuations in the value of portfolio securities will not affect
interest income on existing portfolio securities but will be reflected in the
Fund's net asset value.
 
When-Issued Securities
 
  As described in the Prospectus, the Fund may enter into agreements with
banks or broker-dealers for the purchase or sale of securities at an agreed-
upon price on a specified future date. Such agreements might be entered into,
for example, when the Fund anticipates a decline in interest rates and is able
to obtain a more advantageous yield by committing currently to purchase
securities to be issued later. When the Fund purchases securities in this
manner (i.e. on a when-issued or delayed-delivery basis), it is required to
create a segregated account with the Trust's custodian and to maintain in that
account liquid assets in an amount equal to or greater than, on a daily basis,
the amount of the Fund's when-issued or delayed-delivery commitments. The Fund
will make commitments to purchase on a when-issued or delayed-delivery basis
only securities meeting that Fund's investment criteria. The Fund may take
delivery of these securities or, if it is deemed advisable as a matter of
investment strategy, the Fund may sell these securities before the settlement
date. When the time comes to pay for when-issued or delayed-delivery
securities, the Fund will meet its obligations from then available cash flow
or the sale of securities, or from the sale of the when-issued or delayed-
delivery securities themselves (which may have a value greater or less than
the Fund's payment obligation).
 
Repurchase Agreements
 
  The Fund may enter into repurchase agreements, by which the Fund purchases a
security and obtains a simultaneous commitment from the seller (a bank or, to
the extent permitted by the 1940 Act, a recognized securities dealer) to
repurchase the security at an agreed upon price and date (usually seven days
or less from the date of original purchase). The resale price is in excess of
the purchase price and reflects an agreed upon market rate unrelated to the
coupon rate on the purchased security. Such transactions afford the Fund the
opportunity to earn a return on temporarily available cash at minimal market
risk. While the underlying security may be a bill, certificate of
indebtedness, note or bond issued by an agency, authority or instrumentality
of the United States Government, the obligation of the seller is not
guaranteed by the U.S. Government and there is a risk that the seller may fail
to repurchase the underlying security. In such event, the Fund would attempt
to exercise rights with respect to the underlying security, including possible
disposition in the market. However, the Fund may be subject to various delays
and risks of loss, including (a) possible declines in the value of the
underlying security during the period while the Fund seeks to enforce its
rights thereto, (b) possible reduced levels of income and lack of income
during this period and (c) inability to enforce rights and the expenses
involved in attempted enforcement.

Real Estate Investment Trusts
 
  REITs involve certain unique risks in addition to those risks associated
with investing in the real estate industry in general (such as possible
declines in the value of real estate, lack of availability of mortgage funds
or extended vacancies of property). Equity REITs may be affected by changes in
the value of the underlying property owned by the REITs, while mortgage REITs
may be affected by the quality of any credit extended. REITs are dependent
upon management skills, are not diversified, are subject to heavy cash flow
dependency, risks of default by borrowers and self-liquidation. REITs are also
subject to the possibilities of failing to qualify for tax-free pass-through
of income under the Internal Revenue Code of 1986, as amended (the "Code"),
and failing to maintain their exemptions from registration under the
Investment Company Act of 1940 (the "1940 Act").
 
  Investment in REITs involves risks similar to those associated with
investing in small capitalization companies. REITs may have limited financial
resources, may trade less frequently and in a limited volume and may be
subject to more abrupt or erratic price movements than larger securities.
 
Rule 144A Securities
 
  The Fund may purchase Rule 144A securities. These are privately offered
securities that can be resold only to certain qualified institutional buyers.
Rule 144A securities are treated as illiquid, unless Loomis Sayles has
determined, under guidelines established by the Trust's trustees, that the
particular issue of Rule 144A securities is liquid. Under the guidelines,
Loomis Sayles considers such factors as: (1) the frequency of trades and
quotes for a security; (2) the number of dealers willing to purchase or sell
the security and the number of other potential purchasers; (3) dealer
undertakings to make a market in the security; and (4) the nature of the
security and the nature of the marketplace trades therefor.
 
Foreign Currency Transactions
 
  The Fund may invest in securities of foreign issuers and may enter into
forward foreign currency exchange contracts, or buy or sell options on foreign
currencies, in order to protect against uncertainty in the level of future
foreign exchange rates. Since investment in securities of foreign issuers will
usually involve currencies of foreign countries, and since the Fund may
temporarily hold funds in bank deposits in foreign currencies during the
course of investment programs, the value of the assets of the Fund as measured
in United States dollars may be affected by changes in currency exchange rates
and exchange control regulations, and the Fund may incur costs in connection
with conversion between various currencies.
 
  The Fund may enter into forward contracts under two circumstances. First,
when the Fund enters into a contract for the purchase or sale of a security
denominated or traded in a market in which settlement is made in a foreign
currency, it may desire to "lock in" the U.S. dollar price of the security. By
entering into a forward contract for the purchase or sale, for a fixed amount
of dollars, of the amount of foreign currency involved in the underlying
transactions, the Fund will be able to protect itself against a possible loss
resulting from an adverse change in the relationship between the U.S. dollar
and the subject foreign currency during the period between the date on which
the investment is purchased or sold and the date on which payment is made or
received.
 
  Second, when Loomis Sayles believes that the currency of a particular
country may suffer a substantial decline against another currency, it may
enter into a forward contract to sell, for a fixed amount of another currency,
the amount of the first currency approximating the value of some or all of the
Fund's portfolio investments denominated in the first currency. The precise
matching of the forward contract amounts and the value of the securities
involved will not generally be possible since the future value of such
securities in a currency will change as a consequence of market movements in
the value of those investments between the date the forward contract is
entered into and the date it matures.
 
  The Fund generally will not enter into forward contracts with a term of
greater than one year.
 
  Options on foreign currencies are similar to forward contracts, except that
one party to the option (the holder) is not contractually bound to buy or sell
the specified currency. Instead, the holder has discretion whether
 
                                       6
<PAGE>
 
to "exercise" the option and thereby require the other party to buy or sell
the currency on the terms specified in the option. Options transactions
involve transaction costs and, like forward contract transactions, involve the
risk that the other party may default on its obligations (if the options are
not traded on an established exchange) and the risk that expected movements in
the relative value of currencies may not occur, resulting in an imperfect
hedge or a loss to the Fund.
 
  The Fund, in conjunction with its transactions in forward contracts, options
and futures, will maintain in a segregated account with its custodian liquid
assets with a value, marked to market on a daily basis, sufficient to satisfy
the Fund's outstanding obligations under such contracts, options and futures.
 
Options
 
  As described in the Prospectus, the Fund, may for hedging purposes or to
enhance investment return, purchase and sell call and put options.
 
  An option entitles the holder to receive (in the case of a call option) or
to sell (in the case of a put option) a particular security at a specified
exercise price. An "American style" option allows exercise of the option at
any time during the term of the option. A "European style" option allows an
option to be exercised only at the end of its term. Options may be traded on
or off an established securities exchange.
 
  If the holder of an option wishes to terminate its position, it may seek to
effect a closing sale transaction by selling an option identical to the option
previously purchased. The effect of the purchase is that the previous option
position will be canceled. The Fund will realize a profit from closing out an
option if the price received for selling the offsetting position is more than
the premium paid to purchase the option; the Fund will realize a loss from
closing out an option transaction if the price received for selling the
offsetting option is less than the premium paid to purchase the option.
 
  The use of options involves risks. One risk arises because of the imperfect
correlation between movements in the price of options and movements in the
price of the securities that are the subject of the hedge. The Fund's hedging
strategies will not be fully effective if such imperfect correlation occurs.
 
  Price movement correlation may be distorted by illiquidity in the options
markets and the participation of speculators in such markets. If an
insufficient number of contracts are traded, commercial users may not deal in
options because they do not want to assume the risk that they may not be able
to close out their positions within a reasonable amount of time. In such
instances, options market prices may be driven by different forces than those
driving the market in the underlying securities, and price spreads between
these markets may widen. The participation of speculators in the market
enhances its liquidity. Nonetheless, the trading activities of speculators in
the options markets may create temporary price distortions unrelated to the
market in the underlying securities.
 
  An exchange-traded option may be closed out only on an exchange that
generally provides a liquid secondary market for an option of the same series.
If a liquid secondary market for an exchange-traded option does not exist, it
might not be possible to effect a closing transaction with respect to a
particular option, with the result that the Fund would have to exercise the
option in order to accomplish the desired hedge. 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 or other clearing organization 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 Options Clearing Corporation as a
result of trades on that exchange would continue to be exercisable in
accordance with their terms.
 
                                       7
<PAGE>
 
  The successful use of options depends in part on the ability of Loomis
Sayles to forecast correctly the direction and extent of interest rate, stock
price or currency value movements within a given time frame. To the extent
interest rates, stock prices or currency values move in a direction opposite
to that anticipated, the Fund may realize a loss on the hedging transaction
that is not fully or partially offset by an increase in the value of portfolio
securities. In addition, whether or not interest rates or the relevant stock
price or relevant currency values move during the period that the Fund holds
options positions, the Fund will pay the cost of taking those positions (i.e.,
brokerage costs). As a result of these factors, the Fund's total return for
such period may be less than if it had not engaged in the hedging transaction.
 
  An over-the-counter option (an option not traded on an established exchange)
may be closed out only with the other party to the original option
transaction. While the Fund will seek to enter into over-the-counter options
only with dealers who agree to or are expected to be capable of entering into
closing transactions with the Fund, there can be no assurance that the Fund
will be able to liquidate an over-the-counter option at a favorable price at
any time prior to its expiration. Accordingly, the Fund might have to exercise
an over-the-counter option it holds in order to achieve the intended hedge.
Over-the-counter options are not subject to the protections afforded
purchasers of listed options by the Options Clearing Corporation or other
clearing organization.
 
  The staff of the SEC has taken the position that over-the-counter options
should be treated as illiquid securities for purposes of the Fund's investment
restriction prohibiting it from investing more than 15% of its net assets in
illiquid securities. The Fund intends to comply with this position.
 
  Income earned by the Fund from its hedging activities will be treated as
capital gain and, if not offset by net recognized capital losses incurred by
the Fund, will be distributed to shareholders in taxable distributions.
Although gain from options transactions may hedge against a decline in the
value of the Fund's portfolio securities, that gain, to the extent not offset
by losses, will be distributed in light of certain tax considerations and will
constitute a distribution of that portion of the value preserved against
decline.

                    INVESTMENT ADVISORY AND OTHER SERVICES
 
  Advisory Agreement. Loomis Sayles serves as investment adviser under an
advisory agreement relating to the Loomis Sayles Select Opportunities Fund
dated      , 1999. Under the advisory agreement, Loomis Sayles manages the
investment and reinvestment of the assets of the Fund and generally
administers its affairs subject to the supervision by the Board of Trustees of
the Trust. Loomis Sayles furnishes, at its own expense, all necessary office
space, facilities and equipment, services of executive and other personnel of
the Fund and certain administrative services. For these services, the advisory
agreement provides that the Fund shall pay Loomis Sayles a monthly investment
advisory fee at the annual percentage rate of 0.50% of the Fund's average
daily net assets.
 
  The Trust pays the compensation of its trustees who are not directors,
officers or employees of Loomis Sayles or its affiliates (other than
registered investment companies); registration, filing and other fees in
connection with requirements of regulatory authorities; all charges and
expenses of its custodian and transfer agent; the charges and expenses of its
independent accountants; all brokerage commissions and transfer taxes in
connection with portfolio transactions; all taxes and fees payable to
governmental agencies; the cost of any certificates representing shares of the
Fund; the expenses of meetings of the shareholders and trustees of the Trust;
the charges and expenses of the Trust's legal counsel; interest on any
borrowings by the Fund; the cost of services, including services of counsel,
required in connection with the preparation of, and the cost of printing, the
Trust's registration statements and prospectuses, including amendments and
revisions thereto, annual, semiannual and other periodic reports of the Trust,
and notices and proxy solicitation material furnished to shareholders or
regulatory authorities, to the extent that any such materials relate to the
Trust or its shareholders; and the Trust's expenses of bookkeeping,
accounting, auditing and financial reporting, including related clerical
expenses.
 
  Under the advisory agreement, if the total ordinary business expenses of the
Fund or the Trust as a whole for any fiscal year exceed the lowest applicable
limitation (based on percentage of average net assets or income) prescribed by
any state in which the shares of the Fund or the Trust are qualified for sale,
Loomis Sayles shall pay such excess. Loomis Sayles will not be required to
reduce its fee or pay such expenses to an extent or under circumstances which
would result in the Fund's inability to qualify as a regulated investment
company under the Code. The term "expenses" is defined in the advisory
agreements or in relevant state regulations and excludes brokerage
commissions, taxes, interest, distribution-related expenses and extraordinary
expenses.
 
  As described in the Prospectus, Loomis Sayles has agreed to certain
additional, voluntary arrangements to limit Fund expenses. These arrangements
may be modified or terminated by Loomis Sayles at any time.
 
                                      11
<PAGE>
 
  The advisory agreement provides that it will continue in effect for two
years from its date of execution and thereafter from year to year if its
continuance is approved at least annually (i) by the Board of Trustees of the
Trust or by vote of a majority of the outstanding voting securities of the
Fund and (ii) by vote of a majority of the Trustees who are not "interested
persons" of the Trust, as that term is defined in the 1940 Act, cast in person
at a meeting called for the purpose of voting on such approval. Any amendment
to the advisory agreement must be approved by vote of a majority of the
outstanding voting securities of the Fund and by vote of a majority of the
Trustees who are not such interested persons, cast in person at a meeting
called for the purpose of voting on such approval. The agreement may be
terminated without penalty by vote of the Board of Trustees or by vote of a
majority of the outstanding voting securities of the Fund, upon sixty days'
written notice, or by Loomis Sayles upon ninety days' written notice, and
terminates automatically in the event of its assignment. In addition, the
agreement will automatically terminate if the Trust or the Fund shall at any
time be required by Loomis Sayles to eliminate all reference to the words
"Loomis" and "Sayles" in the name of the Trust or the Fund, unless the
continuance of the agreement after such change of name is approved by a
majority of the outstanding voting securities of the Fund and by a majority of
the Trustees who are not interested persons of the Trust or Loomis Sayles.
 
  The advisory agreement provides that Loomis Sayles shall not be subject to
any liability in connection with the performance of its services thereunder in
the absence of willful misfeasance, bad faith, gross negligence or reckless
disregard of its obligations and duties.
 
  Loomis Sayles acts as investment adviser or subadviser to New England Value
Fund, New England Strategic Income Fund, New England Star Advisers Fund, New
England Star Small Cap Fund and New England Balanced Fund, which are series of
New England Funds Trust I, a registered open-end management investment
company, New England High Income Fund, a series of New England Fund Trust II,
a registered, open-end management investment company, New England Equity
Income Fund, a series of New England Funds Trust III, a registered open-end
management investment company, and to the Balanced Series and the Small Cap
Series of New England Zenith Fund, which is also a registered open-end
management investment company, as well as to Loomis Sayles Investment Trust,
also a registered open-end management investment company. Loomis Sayles also
provides investment advice to certain other open-end management investment
companies and numerous other corporate and fiduciary clients.
 
  The general partner of Loomis Sayles is a special purpose corporation that
is an indirect wholly-owned subsidiary of Nvest Companies, L.P. ("Nvest
Companies"). Nvest Companies' managing general partner, Nvest Corporation, is
a direct wholly-owned subsidiary of Metropolitan Life Insurance Company ("Met
Life"), a mutual life insurance company. Nvest Companies' advising general
partner, Nvest L.P., is a publicly traded company listed on the New York Stock
Exchange. Nvest Corporation is the sole general partner of Nvest L.P.
 
  Certain officers and trustees of the Trust also serve as officers, directors
and trustees of other investment companies and clients advised by Loomis
Sayles. The other investment companies and clients sometimes invest in
securities in which the Fund also invests. If the Fund and such other
investment companies or clients desire to buy or sell the same portfolio
securities at the same time, purchases and sales may be allocated, to the
extent practicable, on a pro rata basis in proportion to the amounts desired
to be purchased or sold for each. It is recognized that in some cases the
practices described in this paragraph could have a detrimental effect on the
price or amount of the securities that the Fund purchases or sells. In other
cases, however, it is believed that these practices may benefit the Fund. It
is the opinion of the trustees that the desirability of retaining Loomis
Sayles as adviser for the Fund outweighs the disadvantages, if any, which
might result from these practices.
 
  Distribution Agreement and Rule 12b-1 Plan. Under an agreement with the
Trust (the "Distribution Agreement"), Loomis Sayles Distributors, L.P. serves
as the general distributor of each class of shares of the Fund. Under this
agreement, Loomis Sayles Distributors, L.P. is not obligated to sell a
specific number of shares. Loomis Sayles Distributors, L.P. bears the cost of
making information about the Fund available through advertising and other
means and the cost of printing and mailing prospectuses to persons other than
shareholders.
 
                                      12
<PAGE>
 
The Fund pays the cost of registering and qualifying their shares under state
and federal securities laws and the distribution of prospectuses to existing
shareholders.
 
  As described in the Prospectuses, the Fund has adopted a Rule 12b-1 plan
("Plan") for its Retail Class shares. The Plan, among other things, permits
the Retail Class shares of the Fund to pay the Fund's distributor (currently
Loomis Sayles Distributors, L.P.) a monthly fee, at annual rates not exceeding
0.25% of the assets of the Retail Class. Pursuant to Rule 12b-1 under the 1940
Act, the Plan (together with the Distribution Agreement) was approved by the
board of trustees, including a majority of the trustees who are not interested
persons of the Trust (as defined in the 1940 Act) and who have no direct or
indirect financial interest in the operations of the Plan or the Distribution
Agreement (the "Independent Trustees").
 
  The Plan may be terminated by vote of a majority of the Independent
Trustees, or by vote of a majority of the outstanding voting securities of the
Retail Class shares of the Fund. The Plan may be amended by vote of the
trustees, including a majority of the Independent Trustees, cast in person at
a meeting called for that purpose. Any change in the Plan that would
materially increase the fees payable thereunder by the Retail Class shares of
the Fund requires approval of the Retail Class shareholders. The Trust's
trustees review quarterly written reports of such costs and the purposes for
which such costs have been incurred. The Plan provides that, for so long as
the Plan is in effect, selection and nomination of those trustees who are not
interested persons of the Trust shall be committed to the discretion of such
disinterested persons.
 
  The Distribution Agreement may be terminated at any time with respect to the
Fund on 60 days' written notice without payment of any penalty by the Trust or
by vote of a majority of the outstanding voting securities of the Fund or by
vote of a majority of the Independent Trustees.
 
  The Distribution Agreement and the Plan will continue in effect for
successive one-year periods, provided that each such continuance is
specifically approved (i) by the vote of a majority of the entire board of
trustees and (ii) by the vote of a majority of the Independent Trustees, in
each case cast in person at a meeting called for that purpose.
 
  Custodial Arrangements. State Street Bank and Trust Company ("State Street
Bank"), Boston, Massachusetts 02102, is the Trust's custodian. As such, State
Street Bank holds in safekeeping certificated securities and cash belonging to
the Fund and, in such capacity, is the registered owner of securities held in
book entry form belonging to the Fund. Upon instruction, State Street Bank
receives and delivers cash and securities of the Fund in connection with Fund
transactions and collects all dividends and other distributions made with
respect to Fund portfolio securities. State Street Bank also maintains certain
accounts and records of the Fund and calculates the total net asset value,
total net income and net asset value per share of the Fund on a daily basis.
 
  Independent Accountants. The Fund's independent accountants are
PricewaterhouseCoopers LLP, One Post Office Square, Boston, Massachusetts.
PricewaterhouseCoopers LLP conducts an annual audit of the Fund's financial
statements, assists in the preparation of the Fund's federal and state income
tax returns and consults with the Fund as to matters of accounting and federal
and state income taxation.
 
                     PORTFOLIO TRANSACTIONS AND BROKERAGE
 
  In placing orders for the purchase and sale of portfolio securities for the
Fund, Loomis Sayles always seeks the best price and execution. Transactions in
unlisted securities are carried out through broker-dealers who make the
primary market for such securities unless, in the judgment of Loomis Sayles, a
more favorable price can be obtained by carrying out such transactions through
other brokers or dealers.
 
  Loomis Sayles selects only brokers or dealers which it believes are
financially responsible, will provide efficient and effective services in
executing, clearing and settling an order and will charge commission rates
 
                                      13
<PAGE>
 
which, when combined with the quality of the foregoing services, will produce
best price and execution for the transaction. This does not necessarily mean
that the lowest available brokerage commission will be paid. However, the
commissions are believed to be competitive with generally prevailing rates.
Loomis Sayles will use its best efforts to obtain information as to the
general level of commission rates being charged by the brokerage community
from time to time and will evaluate the overall reasonableness of brokerage
commissions paid on transactions by reference to such data. In making such
evaluation, all factors affecting liquidity and execution of the order, as
well as the amount of the capital commitment by the broker in connection with
the order, are taken into account. The Fund will not pay a broker a commission
at a higher rate than otherwise available for the same transaction in
recognition of the value of research services provided by the broker or in
recognition of the value of any other services provided by the broker that do
not contribute to the best price and execution of the transaction.
 
  Receipt of research services from brokers may sometimes be a factor in
selecting a broker which Loomis Sayles believes will provide best price and
execution for a transaction. These research services include not only a wide
variety of reports on such matters as economic and political developments,
industries, companies, securities, portfolio strategy, account performance,
daily prices of securities, stock and bond market conditions and projections,
asset allocation and portfolio structure, but also meetings with management
representatives of issuers and with other analysts and specialists. Although
it is not possible to assign an exact dollar value to these services, they
may, to the extent used, tend to reduce Loomis Sayles' expenses. Such services
may be used by Loomis Sayles in servicing other client accounts and in some
cases may not be used with respect to the Fund. Receipt of services or
products other than research from brokers is not a factor in the selection of
brokers.
 
                           DESCRIPTION OF THE TRUST
 
  The Trust, registered with the SEC as a diversified open-end management
investment company, is organized as a Massachusetts business trust under the
laws of Massachusetts by an Agreement and Declaration of Trust (the
"Declaration of Trust") dated February 20, 1991. The Trust currently has
eighteen series: The Bond Fund, Managed Bond Fund, Core Value Fund, Global
Bond Fund, Growth Fund, High Yield Fund, Intermediate Maturity Bond Fund,
International Equity Fund, Investment Grade Bond Fund, Mid-Cap Growth Fund,
Mid-Cap Value Fund, Municipal Bond Fund, Select Opportunities Fund, Short-Term
Bond Fund, Small Cap Growth Fund, Small Cap Value Fund, U.S. Government
Securities Fund and Worldwide Fund.
 
  The Declaration of Trust currently permits the trustees to issue an
unlimited number of full and fractional shares of each series. Each share of
the Fund represents an equal proportionate interest in the Fund with each
other share of the Fund and is entitled to a proportionate interest in the
dividends and distributions from the Fund. The shares of the Fund do not have
any preemptive rights. Upon termination of the Fund, whether pursuant to
liquidation of the Trust or otherwise, shareholders of the Fund are entitled
to share pro rata in the net assets of the Fund available for distribution to
shareholders. The Declaration of Trust also permits the trustees to charge
shareholders directly for custodial, transfer agency and servicing expenses.
 
  The assets received by the Fund for the issue or sale of its shares and all
income, earnings, profits, losses and proceeds therefrom, subject only to the
rights of creditors, are allocated to, and constitute the underlying assets
of, the Fund. The underlying assets are segregated and are charged with the
expenses with respect to the Fund and with a share of the general expenses of
the Trust. Any general expenses of the Trust that are not readily identifiable
as belonging to the Fund are allocated by or under the direction of the
trustees in such manner as the trustees determine to be fair and equitable.
While the expenses of the Trust are allocated to the separate books of account
of each series, certain expenses may be legally chargeable against the assets
of all series.
 
  The Declaration of Trust also permits the trustees, without shareholder
approval, to subdivide the Fund into various classes of shares with such
dividend preferences and other rights as the trustees may designate. Shares of
the Fund are currently divided into two classes, designated Retail Class and
Institutional Class. The trustees may also, without shareholder approval,
establish one or more additional separate portfolios for investments in the
 
                                      14
<PAGE>
 
Trust. Shareholders' investments in such an additional portfolio would be
evidenced by a separate series of shares (i.e., a new "fund").
 
  The Declaration of Trust provides for the perpetual existence of the Trust.
The Trust or the Fund, however, may be terminated at any time by vote of at
least two-thirds of the outstanding shares of the Fund. The Declaration of
Trust further provides that the trustees may also terminate the Trust or the
Fund upon written notice to the shareholders.
 
Voting Rights
 
  As summarized in the Prospectus, shareholders are entitled to one vote for
each full share held (with fractional votes for each fractional share held)
and may vote (to the extent provided in the Declaration of Trust) on the
election of trustees and the termination of the Trust and on other matters
submitted to the vote of shareholders.
 
  The Declaration of Trust provides that on any matter submitted to a vote of
all Trust shareholders, all Trust shares entitled to vote shall be voted
together irrespective of series or sub-series unless the rights of a
particular series or sub-series would be adversely affected by the vote, in
which case a separate vote of that series or sub-series shall also be required
to decide the question. Also, a separate vote shall be held whenever required
by the 1940 Act or any rule thereunder. Rule 18f-2 under the 1940 Act provides
in effect that a class shall be deemed to be affected by a matter unless it is
clear that the interests of each class in the matter are substantially
identical or that the matter does not affect any interest of such class. On
matters affecting an individual series, only shareholders of that series are
entitled to vote. Consistent with the current position of the SEC,
shareholders of all series vote together, irrespective of series, on the
election of trustees and the selection of the Trust's independent accountants,
but shareholders of each series vote separately on other matters requiring
shareholder approval, such as certain changes in investment policies of that
series or the approval of the investment advisory agreement relating to that
series.
 
  There will normally be no meetings of shareholders for the purpose of
electing trustees except that, in accordance with the 1940 Act, (i) the Trust
will hold a shareholders' meeting for the election of trustees at such time as
less than a majority of the trustees holding office have been elected by
shareholders, and (ii) if, as a result of a vacancy on the board of trustees,
less than two-thirds of the trustees holding office have been elected by the
shareholders, that vacancy may be filled only by a vote of the shareholders.
In addition, trustees may be removed from office by a written consent signed
by the holders of two-thirds of the outstanding shares and filed with the
Trust's custodian or by a vote of the holders of two-thirds of the outstanding
shares at a meeting duly called for that purpose, which meeting shall be held
upon the written request of the holders of not less than 10% of the
outstanding shares.
 
  Upon written request by the holders of shares having a net asset value
constituting 1% of the outstanding shares stating that such shareholders wish
to communicate with the other shareholders for the purpose of obtaining the
signatures necessary to demand a meeting to consider removal of a trustee, the
Trust has undertaken to provide a list of shareholders or to disseminate
appropriate materials (at the expense of the requesting shareholders).
 
  Except as set forth above, the trustees shall continue to hold office and
may appoint successor trustees. Voting rights are not cumulative.
 
  No amendment may be made to the Declaration of Trust without the affirmative
vote of a majority of the outstanding shares of the Trust, except (i) to
change the Trust's name or to cure technical problems in the Declaration of
Trust and (ii) to establish, change or eliminate the par value of any shares
(currently all shares have no par value).
 
 
                                      15
<PAGE>
 
Shareholder and Trustee Liability
 
  Under Massachusetts law shareholders could, under certain circumstances, be
held personally liable for the obligations of the Fund of which they are
shareholders. However, the Declaration of Trust disclaims shareholder
liability for acts or obligations of the Fund and requires that notice of such
disclaimer be given in each agreement, obligation or instrument entered into
or executed by the Trust or the trustees. The Declaration of Trust provides
for indemnification out of Fund property for all loss and expense of any
shareholder held personally liable for the obligations of the Fund. Thus, the
risk of a shareholder incurring financial loss on account of shareholder
liability is considered remote since it is limited to circumstances in which
the disclaimer is inoperative and the Fund itself would be unable to meet its
obligations.
 
  The Declaration of Trust further provides that the trustees will not be
liable for errors of judgment or mistakes of fact or law. However, nothing in
the Declaration of Trust protects a trustee against any liability to which the
trustee 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. The By-Laws of the Trust provide for indemnification by
the Trust of the trustees and officers of the Trust except with respect to any
matter as to which any such person did not act in good faith in the reasonable
belief that such action was in or not opposed to the best interests of the
Trust. No officer or trustee may be indemnified against any liability to the
Trust or the Trust's shareholders to which such person 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 or her office.
 
How to Buy Shares
 
  The procedures for purchasing shares of the Fund are summarized in the
Prospectus under "How to Purchase Shares."
 
Net Asset Value
 
  The net asset value of the shares of the Fund is determined by dividing the
Fund's total net assets (the excess of its assets over its liabilities) by the
total number of shares of the Fund outstanding and rounding to the nearest
cent. Such determination is made as of the close of regular trading on the New
York Stock Exchange on each day on which that Exchange is open for
unrestricted trading, and no less frequently than once daily on each day
during which there is sufficient trading in the Fund's portfolio securities
that the value of the Fund's shares might be materially affected. During the
12 months following the date of this Statement of Additional Information, the
New York Stock Exchange is expected to be closed on the following weekdays:
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
Equity securities listed on an established securities exchange or on the
Nasdaq National Market System are normally valued at their last sale price on
the exchange where primarily traded or, if there is no reported sale during
the day, and in the case of over-the-counter securities not so listed, at the
last bid price. Long-term debt securities are valued by a pricing service,
which determines valuations of normal institutional-size trading units of
long-term debt securities. Such valuations are determined using methods based
on market transactions for comparable securities and on various relationships
between securities which are generally recognized by institutional traders.
Other securities for which current market quotations are not readily available
(including restricted securities, if any) and all other assets are taken at
fair value as determined in good faith by the board of trustees, although the
actual calculations may be made by persons acting pursuant to the direction of
the board.
 
  Generally, trading in foreign securities markets is substantially completed
each day at various times prior to the close of regular trading on the New
York Stock Exchange. Occasionally, events affecting the value of foreign fixed
income securities and of equity securities of non-U.S. issuers not traded on a
U.S. exchange may occur between the completion of substantial trading of such
securities for the day and the close of regular trading on the New York Stock
Exchange, which events will not be reflected in the computation of the Fund's
net asset value. If events materially affecting the value of the Fund's
portfolio securities occur during such period, then
 
                                      16
<PAGE>
 
these securities will be valued at their fair value as determined in good
faith by or in accordance with procedures approved by the trustees.
 
                             SHAREHOLDER SERVICES
 
Open Accounts
 
  A shareholder's investment in the Fund is automatically credited to an open
account maintained for the shareholder by Boston Financial Data Services, Inc.
("BFDS"), the shareholder servicing agent for State Street Bank. Certificates
representing shares are issued only upon written request to BFDS but are not
issued for fractional shares. Following each transaction in the account, a
shareholder will receive an account statement disclosing the current balance
of shares owned and the details of recent transactions in the account. After
the close of each fiscal year, BFDS will send each shareholder a statement
providing federal tax information on dividends and distributions paid to the
shareholder during the year. This should be retained as a permanent record.
Shareholders will be charged a fee for duplicate information.
 
  The open account system permits the purchase of full and fractional shares
and, by making the issuance and delivery of certificates representing shares
unnecessary, eliminates the problems of handling and safekeeping certificates,
and the cost and inconvenience of replacing lost, stolen, mutilated or
destroyed certificates.
 
  The costs of maintaining the open account system are borne by the Trust, and
no direct charges are made to shareholders. Although the Trust has no present
intention of making such direct charges to shareholders, it reserves the right
to do so. Shareholders will receive prior notice before any such charges are
made.
 
Systematic Withdrawal Plan
 
  A Systematic Withdrawal Plan, referred to in the Prospectus under
"Shareholder Services--Systematic Withdrawal Plan," provides for monthly,
quarterly, semiannual or annual withdrawal payments of $50 or more from the
account of an eligible shareholder, as provided therein, provided that the
account has a value of at least $25,000 at the time the plan is established.
 
  Payments will be made either to the shareholder or to any other person
designated by the shareholder. If payments are issued to an individual other
than the registered owner(s), a signature guarantee will be required on the
Plan application. All shares in an account that is subject to a Systematic
Withdrawal Plan must be held in an open account rather than in certificated
form. Income dividends and capital gain distributions will be reinvested at
the net asset value determined as of the close of regular trading on the New
York Stock Exchange on the record date for the dividend or distribution.
 
  Since withdrawal payments represent proceeds from liquidation of shares, the
shareholder should recognize that withdrawals may reduce and possibly exhaust
the value of the account, particularly in the event of a decline in net asset
value. Accordingly, the shareholder should consider whether a Systematic
Withdrawal Plan and the specified amounts to be withdrawn are appropriate in
the circumstances. The Fund makes no recommendations or representations in
this regard. It may be appropriate for the shareholder to consult a tax
adviser before establishing such a plan. See "Redemptions" and "Income
Dividends, Capital Gain Distributions and Tax Status" below for certain
information as to federal income taxes.
 
Exchange Privilege
 
  Shareholders may redeem their shares of the Fund and have the proceeds
applied on the same day to purchase shares of the same class of shares of any
other series or of New England Cash Management Trust or New England Tax Exempt
Money Market Trust.
 
  Exchanges may be effected by (1) making a telephone request by calling 800-
626-9390, provided that a special authorization form is on file with BFDS, or
(2) sending a written exchange request to BFDS accompanied
 
                                      17

by an account application for the appropriate fund. The Trust reserves the
right to modify this exchange privilege without prior notice. An exchange
constitutes a sale of the shares for federal income tax purposes on which the
investor may realize a capital gain or loss.
 
IRAs
 
  Under "Shareholder Services--Retirement Plans," the Prospectus refers to
IRAs established under a prototype plan made available by Loomis Sayles. These
plans may be funded with shares of any series.
 
  All income dividends and capital gain distributions of plan participants
must be reinvested. Plan documents and further information can be obtained
from Loomis Sayles.
 
  Check with your financial or tax adviser as to the suitability of Fund
shares for your retirement plan.
 
Redemptions
 
  The procedures for redemption of Fund shares are summarized in the
Prospectus under "How to Redeem Shares."
 
  Except as noted below, signatures on redemption requests must be guaranteed
by commercial banks, trust companies, savings associations, credit unions or
brokerage firms that are members of domestic securities exchanges. Signature
guarantees by notaries public are not acceptable. However, as noted in the
Prospectus, a signature guarantee will not be required if the proceeds of the
redemption do not exceed $50,000 and the proceeds check is made payable to the
registered owner(s) and mailed to the record address.
 
  If a shareholder selects the telephone redemption service in the manner
described in the next paragraph, Fund shares may be redeemed by making a
telephone call directly to BFDS at 800-626-9390. When a telephonic redemption
request is received, the proceeds are wired to the bank account previously
chosen by the shareholder and a nominal wire fee (currently $5.00) is
deducted. Telephonic redemption requests must be received by BFDS prior to the
close of regular trading on the New York Stock Exchange on a day when the
Exchange is open for business. Requests made after that time or on a day when
the New York Stock Exchange is not open for business cannot be accepted by
BFDS and a new request will be necessary.
 
  In order to redeem shares by telephone, a shareholder must either select
this service when completing the Fund application or must do so subsequently
in writing. When selecting the service, a shareholder must designate a bank
account to which the redemption proceeds should be wired. Any change in the
bank account so designated must be made by furnishing to BFDS a written
request with a signature guarantee. Telephone redemptions may only be made if
an investor's bank is a member of the Federal Reserve System or has a
correspondent bank that is a member of the System. If the account is with a
savings bank, it must have only one correspondent bank that is a member of the
System. The Trust, BFDS, Loomis Sayles Distributors, L.P. and State Street
Bank are not responsible for the authenticity of withdrawal instructions
received by telephone.
 
  The redemption price will be the net asset value per share next determined
after the redemption request and any necessary special documentation are
received by BFDS in proper form, less, in the case of the High Yield Fund, a
redemption fee of 2.00% of the amount redeemed with respect to shares of that
series redeemed within one (1) year of purchase, if applicable. Proceeds
resulting from a written redemption request will normally be mailed to the
shareholder within seven days after receipt of a request in good order.
Telephonic redemption proceeds will normally be wired on the first business
day following receipt of a proper redemption request. In those cases where a
shareholder has recently purchased shares by check and the check was received
less than fifteen days prior to the redemption request, the Fund may withhold
redemption proceeds until the check has cleared.
 
  The Fund will normally redeem shares for cash; however, the Fund reserves
the right to pay the redemption price wholly or partly in kind if the board of
trustees of the Trust determines it to be advisable in the interest of
 
                                      18
<PAGE>
 
the remaining shareholders. If portfolio securities are distributed in lieu of
cash, the shareholder will normally incur brokerage commissions upon
subsequent disposition of any such securities. However, the Trust has elected
to be governed by Rule 18f-1 under the 1940 Act pursuant to which the Trust is
obligated to redeem shares solely in cash for any shareholder during any 90-
day period up to the lesser of $250,000 or 1% of the total net asset value of
the Trust at the beginning of such period.
 
  A redemption constitutes a sale of the shares for federal income tax
purposes on which the investor may realize a long- or short-term capital gain
or loss. See "Income Dividends, Capital Gain Distributions and Tax Status."
 
          INCOME DIVIDENDS, CAPITAL GAIN DISTRIBUTIONS AND TAX STATUS
 
  As described in the Prospectus under "Dividends, Capital Gain Distributions
and Taxes" it is the policy of the Fund to pay its shareholders, as dividends,
substantially all net investment income and to distribute annually all net
realized capital gains, if any, after offsetting any capital loss carryovers.
 
  Income dividends and capital gain distributions are payable in full and
fractional shares of the Fund based upon the net asset value determined as of
the close of regular trading on the New York Stock Exchange on the record date
for each dividend or distribution. Shareholders, however, may elect to receive
their income dividends or capital gain distributions, or both, in cash. The
election may be made at any time by submitting a written request directly to
BFDS. In order for a change to be in effect for any dividend or distribution,
it must be received by BFDS on or before the record date for such dividend or
distribution.
 
  As required by federal law, detailed federal tax information will be
furnished to each shareholder for each calendar year on or before January 31
of the succeeding year.
 
  The Fund intends to qualify each year as a regulated investment company
under Subchapter M of the Code. In order to so qualify and to qualify for the
favorable tax treatment accorded regulated investment companies and their
shareholders, the Fund must, among other things, (i) derive at least 90% of
its gross income from dividends, interest, payments with respect to certain
securities loans, gains from the sale of securities or foreign currencies, or
other income (including but not limited to gains from options, futures or
forward contracts) derived with respect to its business of investing in such
stock, securities or currencies; (ii)  distribute with respect to each taxable
year at least 90% of the sum of its taxable net investment income, its tax-
exempt income and the excess, if any, of net short-term capital gains over net
long-term capital losses for such year; and (iii) diversify its holdings so
that at the end of each fiscal quarter (a) at least 50% of the value of its
total assets are invested in cash, U.S. government securities, securities of
other regulated investment companies, and other securities of issuers which
represent, with respect to each issuer, no more than 5% of the value of the
Fund's total assets and 10% of the outstanding voting securities of such
issuer; and (b) not more than 25% of its assets are invested in the securities
(other than those of the U.S. government or other regulated investment
companies) of any one issuer or of two or more issuers which the Fund controls
and which are engaged in the same, similar or related trades and businesses.
To the extent it qualifies for treatment as a regulated investment company,
the Fund will not be subject to federal income tax on income paid to its
shareholders in the form of dividends or capital gain distributions.
 
  An excise tax at the rate of 4% will be imposed on the excess, if any, of
the Fund's "required distribution" over its actual distributions in any
calendar year. Generally, the "required distribution" is 98% of the Fund's
ordinary income for the calendar year plus 98% of its capital gain net income
recognized during the one-year period ending on October 31 (or December 31, if
the Fund so elects) plus undistributed amounts from prior years. The Fund
intends to make distributions sufficient to avoid imposition of the excise
tax. Distributions declared by the Fund during October, November or December
to shareholders of record on a date in any such month and paid by the Fund
during the following January will be treated for federal tax purposes as paid
by the Fund and received by shareholders on December 31 of the year in which
declared.
 
 
                                      19
<PAGE>
 
  Shareholders of the Fund will be subject to federal income taxes on
distributions made by the Fund (other than "exempt-interest dividends" paid by
the Municipal Bond Fund, as described in the Prospectus) whether received in
cash or additional shares of the Fund. Distributions by the Fund of net income
and short-term capital gains, if any, will be taxable to shareholders as
ordinary income. Distributions designated by the Fund as deriving from net
gains on securities held for more than one year will be taxable to
shareholders as long-term capital gain (generally taxed at a rate of 20% for
noncorporate shareholders), without regard to how long a shareholder has held
shares of the Fund.
 
  Dividends and distributions on the Fund's shares are generally subject to
federal income tax as described herein to the extent they do not exceed the
Fund's realized income and gains, even though such dividends and distributions
may economically represent a return of a particular shareholder's investment.
Such distributions are likely to occur in respect of shares purchased at a
time when the Fund's net asset value reflects gains that are either
unrealized, or realized but not distributed. Such realized gains may be
required to be distributed even when the Fund's net asset value also reflects
unrealized losses.
 
  The Fund's transactions, if any, in foreign currencies are likely to result
in a difference between the Fund's book income and taxable income. This
difference may cause a portion of the Fund's income distributions to
constitute a return of capital for tax purposes or require the Fund to make
distributions exceeding book income to avoid excise tax liability and to
qualify as a regulated investment company.
 
  Investment by the Fund in "passive foreign investment companies" could
subject the Fund to U.S. federal income tax or other charges on the proceeds
from the sale of its investment in such a company; however, this tax can be
avoided by making an election to mark such investments to market annually or
to treat the passive foreign investment company as a "qualified electing
fund." A "passive foreign investment company" is any foreign corporation: (i)
75% or more of the income of which for the taxable year is passive income, or
(ii) the average percentage of the assets of which (generally by value, but by
adjusted tax basis in certain cases) that produce or are held for the
production of passive income is at least 50 percent. Generally, passive income
for this purpose means dividends, interest (including income equivalent to
interest), royalties, rents, annuities, the excess of gains over losses from
certain property transactions and commodities transactions, and foreign
currency gains. Passive income for this purpose does not include rents and
royalties received by the foreign corporation from active business and certain
income received from related persons.
 
  If the Fund engages in hedging transactions, including hedging transactions
in options, futures contracts, and straddles, or other similar transactions,
it will be subject to special tax rules (including constructive sale, mark-to-
market, straddle, wash sale, and short sale rules), the effect of which may be
to accelerate income to the Fund, defer losses to the Fund, cause adjustments
in the holding periods of the Fund's securities, or convert short-term capital
losses into long-term capital losses. These rules could therefore affect the
amount, timing and character of distributions to shareholders. The Fund will
endeavor to make any available elections pertaining to such transactions in a
manner believed to be in the best interests of the Fund.
 
  The Fund's investment in securities issued at a discount and certain other
obligations will (and investments in securities purchased at a discount may)
require the Fund to accrue and distribute income not yet received. In such
cases, the Fund may be required to sell assets (including when it is not
advantageous to do so) to generate the cash necessary to distribute as
dividends to its shareholders all of its income and gains and therefore to
eliminate any tax liability at the Fund level.
 
  Generally the Fund may designate dividends eligible for the dividends-
received deduction only to the extent that such dividends are derived from
dividends paid to the Fund with respect to which Fund could have taken the
dividends-received deduction if it had been a regular corporation. The
dividends-received deduction is not available to non-corporate shareholders,
Subchapter S corporations or corporations who do not hold their shares for at
least 46 days during the 90-day period beginning on the date that is 45 days
before the ex-dividend date.
 
 
                                      20
<PAGE>
 
  Redemptions and exchanges of the Fund's shares are taxable events and,
accordingly, shareholders may realize gains and losses on these transactions.
In general, any gain realized upon a taxable disposition of shares will be
treated as long-term capital gain if the shares have been held for more than
one year. Otherwise the gain on the sale, exchange or redemption of Fund
shares will be treated as short-term capital gain. However, if a shareholder
sells Fund shares at a loss within six months after purchasing the shares, the
loss will be treated as a long-term capital loss to the extent of any long-
term capital gain distributions received by the shareholder. Furthermore, no
loss will be allowed on the sale of Fund shares to the extent the shareholder
acquired other shares of the same Fund within 30 days prior to the sale of the
loss shares or 30 days after such sale.
 
  The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and regulations currently in effect. For the complete
provisions, reference should be made to the pertinent Code sections and
regulations. The Code and regulations are subject to change by legislative or
administrative action.
 
  Dividends and distributions also may be subject to foreign, state and local
taxes. Shareholders are urged to consult their tax advisers regarding specific
questions as to federal, state, foreign, or local taxes.
 
  The foregoing discussion relates solely to U.S. federal income tax law. Non-
U.S. investors should consult their tax advisers concerning the tax
consequences of ownership of shares of the Fund, including the possibility
that distributions may be subject to a 30% United States withholding tax (or a
reduced rate of withholding provided by treaty). The Internal Revenue Service
recently revised its regulations affecting the application to foreign
investors of the back-up withholding tax rules. The new regulations will
generally be effective for payments made on or after January 1, 2001 (although
transition rules will apply). In some circumstances, the new rules will
increase the certification and filing requirements imposed on foreign
investors in order to qualify for exemption from the 31% back-up withholding
tax and for reduced withholding tax rates under income tax treaties. Foreign
investors in the Fund should consult their advisors with respect to the
potential application of these new regulations.
 
                     CALCULATION OF YIELD AND TOTAL RETURN
 
  Yield. Yield with respect to the Fund will be computed by dividing the
Fund's net investment income for a recent 30-day period by the maximum
offering price (reduced by any undeclared earned income expected to be paid
shortly as a dividend) on the last trading day of that period. Net investment
income will reflect amortization of any market value premium or discount of
fixed income securities (except for obligations backed by mortgages or other
assets) and may include recognition of a pro rata portion of the stated
dividend rate of dividend paying portfolio securities. The Fund's yields will
vary from time to time depending upon market conditions, the composition of
the Fund's portfolios and operating expenses of the Trust allocated to the
Fund. These factors, and possible differences in the methods used in
calculating yield, should be considered when comparing the Fund's yield to
yields published for other investment companies and other investment vehicles.
Yield should also be considered relative to changes in the value of the Fund's
shares and to the relative risks associated with the investment objectives and
policies of the Fund.
 
  At any time in the future, yields may be higher or lower than past yields
and there can be no assurance that any historical results will continue.
 
  Investors in the Fund are specifically advised that the net asset value per
share of the Fund may vary, just as yields for the Fund may vary. An
investor's focus on yield to the exclusion of the consideration of the value
of shares of the Fund may result in the investor's misunderstanding the total
return he or she may derive from the Fund.
 
  Total Return. Total Return with respect to the Fund is a measure of the
change in value of an investment in the Fund over the period covered, and
assumes any dividends or capital gains distributions are reinvested
immediately, rather than paid to the investor in cash. The formula for total
return used herein includes four steps:
 
                                      21
<PAGE>
 
(1) adding to the total number of shares purchased through a hypothetical
$1,000 investment in the Fund all additional shares which would have been
purchased if all dividends and distributions paid or distributed during the
period had been immediately reinvested; (2) calculating the value of the
hypothetical initial investment of $1,000 as of the end of the period by
multiplying the total number of shares owned at the end of the period by the
net asset value per share on the last trading day of the period; (3) assuming
redemption at the end of the period; and (4) dividing the resulting account
value by the initial $1,000 investment.
 
                            PERFORMANCE COMPARISONS
 
  Total Return. The Fund may from time to time include its total return
information in advertisements or in information furnished to present or
prospective shareholders. The Fund may from time to time include in
advertisements or information furnished to present or prospective shareholders
(i) the ranking of performance figures relative to such figures for groups of
mutual funds categorized by Lipper Analytical Services, Inc. as having similar
investment objectives, (ii) the rating assigned to the Fund by Morningstar,
Inc. based on the Fund's risk-adjusted performance relative to other mutual
funds in its broad investment class, and/or (iii) the ranking of performance
figures relative to such figures for mutual funds in its general investment
category as determined by CDA/Weisenberger's Management Results.
 
  Volatility. The Fund may quote various measures of its volatility and
benchmark correlation. In addition, the Fund may compare these measures to
those of other funds and indices. Measures of volatility seek to compare the
Fund's historical share price fluctuations or total returns to those of a
benchmark. Measures of benchmark correlation indicate the extent to which the
Fund's returns change in ways similar to those of the benchmark. All measures
of volatility and correlation are calculated using averages of historical
data. The Fund may utilize charts and graphs to present the Fund's volatility
and average annual total return. The Fund may also discuss or illustrate
examples of interest rate sensitivity.
 
  Lipper Analytical Services, Inc. distributes mutual fund rankings monthly.
The rankings are based on total return performance calculated by Lipper,
generally reflecting changes in net asset value adjusted for reinvestment of
capital gains and income dividends. They do not reflect deduction of any sales
charges. Lipper rankings cover a variety of performance periods, including
year-to-date, 1-year, 5-year, and 10-year performance. Lipper classifies
mutual funds by investment objective and asset category.
 
  Morningstar, Inc. distributes mutual fund ratings monthly. The ratings are
divided into five groups: highest, above average, neutral, below average and
lowest. They represent a fund's historical risk/reward ratio relative to other
funds in its broad investment class as determined by Morningstar, Inc.
Morningstar ratings cover a variety of performance periods, including 3-year,
5-year, 10-year and overall performance. The performance factor for the
overall rating is a weighted-average return performance (if available)
reflecting deduction of expenses and sales charges. Performance is adjusted
using quantitative techniques to reflect the risk profile of the fund. The
ratings are derived from a purely quantitative system that does not utilize
the subjective criteria customarily employed by rating agencies such as
Standard & Poor's and Moody's Investor Service, Inc.
 
  CDA/Weisenberger's Management Results publishes mutual fund rankings and is
distributed monthly. The rankings are based entirely on total return
calculated by Weisenberger for periods such as year-to-date, 1-year, 3-year,
5-year and 10-year. Mutual funds are ranked in general categories (e.g.,
international bond, international equity, municipal bond, and maximum capital
gain). Weisenberger rankings do not reflect deduction of sales charges or
fees.
 
  Performance information may also be used to compare the performance of the
Fund to certain widely acknowledged standards or indices for stock and bond
market performance, such as those listed below.
 
  Consumer Price Index. The Consumer Price Index, published by the U.S. Bureau
of Labor Statistics, is a statistical measure of changes, over time, in the
prices of goods and services in major expenditure groups.

  Dow Jones Industrial Average. The Dow Jones Industrial Average is a market
value-weighted and unmanaged index of 30 large industrial stocks traded on the
New York Stock Exchange.
 
  Standard & Poor's/Barra Growth Index. The Standard & Poor's/Barra Growth
Index is constructed by ranking the securities in the S&P 500 by price-to-book
ratio and including the securities with the highest price-to-book ratios that
represent approximately half of the market capitalization of the S&P 500.
 
  Standard & Poor's/Barra Value Index. The Standard & Poor's/Barra Value Index
is constructed by ranking the securities in the S&P 500 by price-to-book ratio
and including the securities with the lowest price-to-book ratios that
represent approximately half of the market capitalization of the S&P 500.
 
  Standard & Poor's ("S&P") Mid-Cap 400 Index. The S&P Mid-Cap 400 Index
consists of 400 domestic stocks chosen for market size, liquidity and industry
group representation. It is a market-weighted (stock price times shares
outstanding) with each stock affecting the index in proportion to its value.
The index is comprised of industrial, utility, financial and transportation
stocks, in size order.
 
  Standard & Poor's 500 Composite Stock Price Index (the "S&P 500"). The S&P
500 is a market value-weighted and unmanaged index showing the changes in the
aggregate market value of 500 stocks relative to the base period 1941-43. The
S&P 500 is composed almost entirely of common stocks of companies listed on
the New York Stock Exchange, although the common stocks of a few companies
listed on the American Stock Exchange or traded over-the-counter are included.
The 500 companies represented include 400 industrial, 60 transportation and 40
financial services concerns. The S&P 500 represents about 80% of the market
value of all issues traded on the New York Stock Exchange. The S&P 500 is the
most common index for the overall U.S. stock market.
 
  From time to time, articles about the Fund regarding performance, rankings
and other characteristics of the Fund may appear in publications including,
but not limited to, the publications included in Appendix A. In particular,
some or all of these publications may publish their own rankings or
performance reviews of mutual funds, including the Fund. References to or
reprints of such articles may be used in the Fund's promotional literature.
References to articles regarding personnel of Loomis Sayles who have portfolio
management responsibility may also be used in the Fund's promotional
literature. For additional information about the Fund's advertising and

           No Longer Applicable.

Item 27.   Indemnification
           ---------------

Article VIII of the Registrant's Agreement and Declaration of Trust (Exhibit 1
hereto) and Article 4 of the Registrant's By-Laws (Exhibit 2 hereto) provide for
indemnification of its Trustees and Officers. The effect of these provisions is
to provide indemnification for each of the Registrant's Trustees and Officers
against liabilities and counsel fees reasonably incurred in connection with the
defense of any legal proceeding in which such Trustee or Officer may be involved
by reason of being or having been a Trustee or Officer, except with respect to
any matter as to which such Trustee or Officer shall have been adjudicated not
to have acted in good faith in the reasonable belief that such Trustee's or
Officer's action was in the best interest of the Registrant, and except that no
Trustee or Officer shall be indemnified against any liability to the Registrant
or its shareholders to which such Trustee or Officer otherwise would be subject
by reason of willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of such Trustee's or Officer's
office.

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

          (h) brokers' commissions and issue and transfer taxes chargeable to
     the Trust in connection with securities transactions to which the Trust is
     a party;

          (i) taxes and fees payable by the Trust to Federal, State or other
     governmental agencies;
 
          (j) any cost of certificates representing shares of the Series;

          (k) legal fees and expenses in connection with the affairs of the
     Trust including registering and qualifying its shares with Federal and
     State regulatory authorities;

          (l) expenses of meetings of shareholders and Trustees of the Trust;

          (m)  interest, including interest on borrowings by the Trust;

          (n) the cost of services, including services of counsel, required in
     connection with the preparation of the Trust's registration statements and

     solicitation material furnished to shareholders of the Trust or regulatory
     authorities; and

          (o) the Trust's expenses of bookkeeping, accounting, auditing and
     financial reporting, including related clerical expenses.

     6.   The services of the Adviser to the Trust hereunder are not to be
deemed exclusive and the Adviser shall be free to render similar services to
others, so long as its services hereunder are not impaired thereby.

     7.   As full compensation for all services rendered, facilities furnished
and expenses borne by the Adviser hereunder, the Trust shall pay the Adviser
compensation at the annual percentage rate of 0.50%, or such lesser rate as the
Adviser may agree to from time to time. Such compensation shall be payable
monthly in arrears or at such other intervals, not less frequently than

<PAGE>
 
in accordance with the foregoing sentence, the Series and the Trust shall each
be deemed to be a separate fund subject to such limitations. Should the
applicable state limitation provisions fail to specify how the average net
assets of the Trust or belonging to the Series are to be calculated, that figure
shall be calculated by reference to the average daily net assets of the Trust or
the Series, as the case may be.

     9.   It is understood that any of the shareholders, trustees, officers,
employees and agents of the Trust may be a partner, shareholder, director,
officer, employee or agent of, or be otherwise interested in, the Adviser, any
affiliated person of the Adviser, any organization in which the Adviser may have
an interest or any organization which may have an interest in the Adviser; that
the Adviser, any such affiliated person or any such organization may have an
interest in the Trust; and that the existence of any such dual interest shall
not affect the validity hereof or of any transactions hereunder except as
otherwise provided in the Agreement and Declaration of Trust of the Trust and
the Partnership Agreement of the Adviser, respectively, or by specific
provisions of applicable law.

     10.  This Agreement shall become effective as of the date of its execution,
and

          (a) unless otherwise terminated, this Agreement shall continue in
     effect for two years from the date of execution, and from year to year
     thereafter only so long as such continuance is specifically approved at
     least annually (i) by the Board of Trustees of the Trust or by vote of a
     majority of the outstanding voting securities of the Series, and (ii) by
     vote of a majority of the Trustees of the Trust who are not interested
     persons of the Trust or the Adviser, cast in person at a meeting called for
     the purpose of voting on such approval;

          (b) this Agreement may at any time be terminated on sixty days'
     written notice to the Adviser either by vote of the Board of Trustees of
     the Trust or by vote of a majority of the outstanding voting securities of
     the Series;

          (c) this Agreement shall automatically terminate in the event of its
     assignment;

          (d) this Agreement may be terminated by the Adviser on ninety days'
     written notice to the Trust;

          (e) if the Adviser requires the Trust or the Series to change its name
     so as to eliminate all references to the words "Loomis" or "Sayles," then
     this Agreement shall automatically terminate at the time of such change
     unless the continuance of this Agreement after such change shall have been
     specifically approved by vote of a majority of the outstanding voting
     securities of the Series and by vote of a majority of the Trustees of the
     Trust who are not interested persons of the Trust or the Adviser, cast in
     person at a meeting called for the purpose of voting on such approval.

     Termination of this Agreement pursuant to this section 10 shall be without
payment of any penalty.

     11.  This Agreement may be amended at any time by mutual consent of the
parties, provided that such consent on the part of the Trust shall have been
approved by vote of a majority of the outstanding voting securities of the
Series and by vote of a majority of the Trustees of the Trust who are not
interested persons of the Trust or the Adviser, cast in person at a meeting
called for the purposes of voting on such approval.

     12.  For the purposes of this Agreement, the terms "vote of a majority of
the outstanding voting securities," "interested person," "affiliated person" and
"assignment" shall have their respective meanings defined in the Investment
Company Act of 1940 and the rules and regulations thereunder, subject, however,
to such exemptions as may be granted by the Securities and Exchange Commission
under said Act.  References in this Agreement to any assets, property or
liabilities "belonging to" the Series shall have the meaning defined in the
Trust's Agreement and Declaration of Trust and By-Laws as amended from time to
time.

     13.  In the absence of willful misfeasance, bad faith or gross negligence
on the part of the Adviser, or reckless disregard of its obligations and duties
hereunder, the Adviser shall not be subject to any liability to the Trust, to
any shareholder of the Trust or to any other person, firm or organization, for
any act or omission in the course of, or connected with, rendering services
hereunder.

                           Selected Dealer Agreement



     Selected Dealer Agreement between Loomis Sayles Distributors, L.P.
("Distributor") and ___________________________________________________________
("Dealer") dated as of                                    , 1999.

     WHEREAS, Loomis Sayles Funds (the "Trust") has appointed Distributor as its
exclusive agent to sell and distribute each class of shares of each series (each
a "Fund") of the Trust, which shares are distributed by Distributor and sold by
the Trust at their net asset value; and

     WHEREAS, Distributor and Dealer desire that Dealer participate as a
selected dealer in the distribution of one or more classes of shares of any and
all of the Funds and of any Funds hereafter created for which Distributor is the
distributor.

     NOW, THEREFORE, Distributor and Dealer hereby agree to the following terms
and conditions:

1.   This Agreement relates to the class or classes of shares (the "Shares") of
     the Fund or Funds specified in Appendix A hereto.

2.   Dealer will offer and sell Shares only at the public offering prices which
     shall be currently in effect, in accordance with the terms of the then
     current Prospectus of the relevant Fund.  Dealer agrees to act only as
     principal in such transactions and shall not have authority hereunder to
     act as an agent, broker or employee with respect to the Trust, Distributor
     or any other dealer in any respect.  All orders are subject to acceptance
     by the Trust and become effective only upon confirmation by Distributor to
     Dealer on behalf of the Trust.

3.   As a selected dealer, Dealer is hereby authorized (i) to place orders
     through Distributor with the Funds for their Shares to be sold by the Funds
     to Dealer subject to the applicable terms and conditions governing the
     placement of orders set forth in the Distribution Agreement between the
     Trust and the Distributor and subject to the terms set forth in the then
     current Prospectus and Statement of Additional Information relating to the
     relevant class of Shares of the relevant Fund, and (ii) to tender Shares
     directly to the Funds or their agent for redemption subject to the
     applicable terms and conditions set forth in said Distribution Agreement,
     Prospectus and Statement of Additional Information.

4.   Repurchase of Shares will be made at the net asset value of such Shares in
     accordance with the applicable then current Prospectus relating to the
     relevant class of Shares of the relevant Fund.

5.   Each party hereto represents that it is a member in good standing of the
     National Association of Securities Dealers, Inc. (the "NASD") and agrees to
     notify the other promptly should it cease to be a member of the NASD and to
     the automatic termination of this Agreement at such time as it 

                                      -1-
<PAGE>
 
     ceases to be such a member. Further, each party hereto agrees to abide by
     the Conduct Rules of the NASD.

6.   This Agreement is in all respects subject to Rule 2830 of the Rules of the
     NASD, which shall control any provisions to the contrary in this Agreement.

7.   Dealer agrees:

     (a)  To purchase Shares only from the Trust through Distributor or only
          from Dealer's customers.

     (b)  To purchase Shares from the Trust only for the purpose of covering
          purchase orders already received or for Dealer's bona fide investment.

     (c)  In each instance in which Dealer's customer or a nominee thereof will
          be a shareholder of record of the Trust, to provide such customer's
          correct taxpayer identification number or social security number, and
          such other information and documents as the Trust may reasonably
          require for purposes of compliance with applicable tax withholding
          requirements, in connection with opening any shareholder account for
          such customer or nominee.

     (d)  That Dealer will not purchase any Shares from Dealer's customers at
          prices lower than the redemption or repurchase prices next quoted by
          the Fund.  Dealer shall be permitted to sell Shares to the Funds at
          the repurchase prices currently established for such Shares.

     (e)  That Dealer will not intentionally withhold placing customers' orders
          for Shares so as to profit Dealer as a result of such withholding.

8.   Distributor, as agent for each Fund, shall not accept from Dealer any
     conditional orders for Shares. Delivery of certificates, if any, for Shares
     purchased shall be made by a Fund only against receipt of the purchase
     price, and only upon request.  If payment for the Shares purchased and all
     necessary applications and documents required by the applicable Fund or
     Distributor are not received within three business days or such shorter
     time as may be required by law, the sale may be canceled forthwith without
     any responsibility or liability on Distributor's part or on the part of the
     applicable Fund (in which case Dealer will be responsible for any loss,
     including loss of profit, suffered by a Fund resulting from Dealer's
     failure to make payments or provide documents as aforesaid), or, at
     Distributor's option, Distributor may cause the Shares ordered to be
     redeemed by the relevant Fund (in which case Distributor and the Trust may
     hold Dealer responsible for any loss suffered by either of them in
     connection with or as a result of such redemption).

9.   Dealer will not offer or sell any of the Shares except under circumstances
     that will result in compliance with all applicable federal or state
     securities laws and, in connection with sales and offers to sell Shares,
     Dealer will furnish to each person to whom any such sale or offer is made a
     copy of the applicable then current Prospectus relating to the relevant
     class of Shares of the relevant Fund.  Distributor shall be under no
     liability to Dealer except for lack of good faith and 

                                      -2-
<PAGE>
 
     for obligations expressly assumed by Distributor herein. Notice and other
     applicable filings for Shares of the Funds in various states is the
     responsibility of Distributor or one of its affiliates. Nothing herein
     contained, however, shall be deemed to be a condition, stipulation or
     provision binding any persons acquiring any security to waive compliance
     with any provision of the Securities Act of 1933 or of the Rules and
     Regulations of the Securities and Exchange Commission or to relieve the
     parties hereto from any liability arising under the Securities Act of 1933.
     Dealer will use its best efforts in the development and promotion of sales
     of Shares and will be responsible for the proper instruction and training
     of all sales personnel employed by it.

10.  No person is authorized to make any representations concerning Shares of
     the Funds except those contained in the applicable then current Prospectus
     and Statement of Additional Information and printed information issued by
     the Trust or by Distributor as information supplemental to the applicable
     Prospectus.  Distributor shall supply such Prospectuses at no cost to
     Dealer and reasonable quantities of supplemental sales literature, sales
     bulletins and additional information as issued.  Dealer agrees not to use
     other advertising or sales material relating to the Funds, unless approved
     in writing by Distributor in advance of such use.  Any printed information
     furnished by Distributor, other than the applicable then current Prospectus
     and Statement of Additional Information and any periodic reports and proxy
     solicitation materials of the Trust, are Distributor's sole responsibility
     and not the responsibility of the Trust, and Dealer agrees that the Trust
     shall have no liability or responsibility to Dealer in these respects
     unless expressly assumed in connection therewith.

11.  Dealer agrees to provide certain additional services to the extent, if any,
     set forth in Appendixes B, C and/or D hereto, as from time to time amended,
     for such compensation as is set forth therein. Dealer acknowledges that
     Distributor shall pay any compensation to Dealer described in any such
     Appendix only out of such monies as may be received for such purpose by
     Distributor from either the Funds or Loomis, Sayles & Company, L.P.;
     accordingly, any obligation of Distributor to Dealer to pay any such
     compensation shall not arise unless and until receipt by Distributor from
     the Funds or Loomis, Sayles & Company, L.P. of monies intended to be used
     by Distributor for such purpose and in amounts sufficient for such purpose.

12.  Either party may terminate this Agreement, without cause, by giving 30
     days' written notice to the other party.  Distributor may terminate this
     Agreement for cause upon the violation by Dealer of any of the provisions
     hereof, such termination to be effective on the date notice of such
     termination is sent to Dealer.  Any notice under this Agreement shall be in
     writing and shall be deemed to have been given on the date on which it was
     either delivered to the other party, or was mailed postpaid or sent by
     facsimile transmission (with machine confirmation) or delivered to a
     telegraph office for transmission to the other party, at its Notice Address
     as shown on the signature page of this Agreement.

13.  This Agreement may be amended from time to time by Distributor upon 10
     days' written notice to Dealer.  This Agreement shall inure to the benefit
     of the successors and assigns of either party hereto, provided, however,
     that Dealer may not assign this Agreement without the prior written consent
     of Distributor.

                                      -3-

14.  This Agreement shall be construed in accordance with the laws of The
     Commonwealth of Massachusetts.  Any disputes between the parties hereto
     arising in connection with this Agreement shall be submitted to arbitration
     in accordance with the Code of Arbitration Procedure of the National
     Association of Securities Dealers, Inc., or similar rules or code
     hereinafter adopted as in effect at the time of the submission of any such
     dispute.

15.  This Agreement shall be binding upon both parties hereto when executed by
     both parties and supersedes any prior agreement or understanding between
     Distributor and Dealer with respect to the sale of Shares of any of the
     Funds of the Trust.

     In addition to fulfilling the obligations provided in the attached Selected
Dealer Agreement, Dealer agrees to use its best efforts to make available, to
its customers who from time to time beneficially own Retail Class Shares in
accounts for which Dealer is the dealer of record as reflected in the records of
the Distributor ("Dealer Accounts"), such personal services and information as
are customarily provided by full-service securities brokers to their customers
with respect to such customers' investments in mutual funds for which such
brokers are the dealers of record.  In recognition of Dealer's provision of such
services to such customers of Dealer, Distributor agrees, subject to the
provisions of the second sentence of Section 11 of the attached Selected Dealer
Agreement, to pay Dealer, with respect to each calendar quarter during which the
attached Selected Dealer Agreement is in effect, a fee at the Annual Fee Rate
set forth below, applied to the average daily net asset value of all Retail
Class Shares of the Funds that are held during such quarter by Dealer Accounts.
Such fee will be accrued daily and paid no less often than quarterly by the 45th
day of the subsequent calendar quarter.  The Annual Fee Rate set forth below is
subject to change by Distributor from time to time, upon 10 days' written
notice, and any orders to purchase Retail Class Shares that are received by the
Trust after the effective date of such change will be subject to the rate(s) in
effect at the time of receipt of such order by the Funds.

     The foregoing fee may be paid by Distributor to Dealer out of amounts
received by Distributor from the Funds pursuant to the distribution and
servicing plans (the "Plans") relating to Retail Class Shares adopted pursuant
to Rule 12b-1 under the Investment Company Act of 1940 by each Fund that offers
Retail Class Shares.  Any payments made pursuant to this Appendix C shall be
subject to the following terms and conditions:

     (a)  Dealer shall provide to Distributor and the Trust each calender
          quarter such information as shall reasonably by requested by
          Distributor or the Trustees of the Trust with respect to the fee paid
          to the Dealer pursuant to this Appendix C.

     (b)  Dealer will permit representatives of the Trust and Distributor
          reasonable access to its personnel and records to enable them to
          monitor the quality of services being provided by Dealer pursuant to
          this Agreement.  Dealer shall promptly deliver to the Trustees of the
          Trust such information as is reasonably necessary to permit the
          Trustees to make an informed determination whether to continue the
          Plans or any of them.

                           Amended and Restated Plan
                           -------------------------
       pursuant to Rule 18f-3(d) under the Investment Company Act of 1940
       ------------------------------------------------------------------

                             Effective May 3, 1999

     Each of the series of Loomis Sayles Funds (the "Trust") managed by Loomis,
Sayles & Company, L.P. ("Loomis Sayles") (each a "Fund" and, together, the
"Funds") may from time to time issue one or more of the following classes of
shares:  Retail Class shares, Institutional Class shares, Admin Class shares and
Class J shares.  Each class is subject to such investment minimums and other
conditions of eligibility as are set forth in the Funds' registration statements
as from time to time in effect.  The differences in expenses among these classes
of shares, and the conversion and exchange features of each class of shares, are
set forth below in this Plan.  Expenses are allocated among the classes of
shares of each Fund based upon the net assets of each Fund attributable to
shares of each class, except (1) as noted below and (2) each class may bear
Omnibus Account Expenses relating to holders of shares of such class. Omnibus
Account Expenses include payments made for sub-accounting, recordkeeping,
investor communications, investor servicing, proxy or voting instruction
solicitation or tabulation and similar functions and services performed or
provided to or with respect to investors who hold shares of such class through
any kind of omnibus, "street name," nominee or similar account (that is, an
account of record that represents ownership by a beneficial owner or owners
other than the owner of record).

     This Plan is subject to change, to the extent permitted by law and by the
Agreement and Declaration of Trust and By-laws of each Fund, by action of the
Trustees of each Fund.

Plans, Retail Class shares may pay up to 0.25% of the relevant Fund's average
