                                   THE TRUST

    Each 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.  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
  
 Loomis Sayles Growth Fund
 -------------------------

    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. Investments are selected based
 on their growth potential; current income is not a consideration.  The Fund may
 invest in companies with relatively small market capitalization, as well as in
 larger companies.  The Fund may invest a limited portion of its assets in
 securities of foreign issuers.
     
 Loomis Sayles Core Value Fund 
 -----------------------------      

    The Fund's investment objective is long-term growth of capital and income.

    The Fund seeks to achieve its objective by investing substantially all of
 its assets in common stocks or their equivalent which Loomis Sayles considers
 to be undervalued in relation to the issuer's earnings, dividends, assets and
 growth prospects. The Fund may invest a limited portion of its assets in
 securities of foreign issuers.
     
 Loomis Sayles Small Cap Value Fund
 ----------------------------------       

    The Fund's investment objective is long-term capital growth from investments
 in common stocks or their equivalent.

    The Fund seeks to achieve its objective by investing primarily in stocks of
 small cap companies with good earnings growth potential that Loomis Sayles
 believes are undervalued by the market.  The Fund will normally invest at least
 65% of its total assets in companies with market capitalization of less than $1
 billion and may invest up to 35% of its assets in larger companies.  Loomis
 Sayles seeks to build a core small cap portfolio of stocks of solid companies
 with reasonable growth prospects and that are attractively priced in relation
 to the companies' earnings with a smaller emphasis on special situations and
 turnarounds (companies that have experienced significant business problems but
 which Loomis Sayles believes have favorable prospects for recovery), as well as
 unrecognized stocks.  The Fund may invest a limited portion of its assets in
 securities of foreign issuers. Current income is not a consideration in
 selecting the Fund's investments.

 Loomis Sayles International Equity Fund
 ---------------------------------------

    The Fund's investment objective is high total investment return through a
 combination of capital appreciation and current income.

    The Fund seeks to achieve its objective by investing primarily in equity
 securities of companies organized or headquartered outside the United States.
 Under normal conditions the Fund will invest at least 65% of its total assets
 in equity securities of issuers of at least three countries outside the United
 States, and no more than 20% of its assets in issuers headquartered in any one
 country.  For temporary defensive purposes, the Fund may invest as much as 100%
 of its assets in issuers from one or two countries, which may include the
 United States.

 Loomis Sayles Worldwide Fund
 ----------------------------

    The Fund's investment objective is high total investment return through a
 combination of capital appreciation and current income.
<PAGE>
 
    The Fund seeks to achieve its objective by investing in U.S. and foreign
 equity and debt securities.  The allocation of the Fund's assets among the four
 sectors of domestic equities, international equities, domestic bonds and
 international bonds will be made by Loomis Sayles' Global Asset Allocation
 Group.  The Fund will normally invest its assets in securities of issuers from
 at least three countries, one of which will be the United States.  The Fund may
 invest less than 35% of its assets in fixed income securities of below
 investment grade quality (commonly referred to as "junk bonds").  The Fund may
 also invest in collateralized mortgage obligations ("CMOs") and Rule 144A
 securities.  See "More Information about the Funds' Investments" below.

    The Fund may engage in options and forward contract transactions to hedge
 against changes in the value of securities and the currencies in which they are
 denominated.
     
 Loomis Sayles Small Company Growth Fund
 ---------------------------------------

    The Fund's investment objective is long-term capital growth from investments
 in common stocks or their equivalent.

    The Fund seeks to attain its objective by investing primarily in stocks of
 small, rapidly growing companies that Loomis Sayles believes have the potential
 for accelerating earnings growth and rising profit margins.  The Fund will
 normally invest at least 65% of its total assets in companies with market
 capitalization of less than $1 billion and may invest up to 35% of its total
 assets in larger companies.  Loomis Sayles seeks companies that have
 distinctive products, technologies, or services; dynamic earnings growth;
 prospects for a high level of profitability; and outstanding management.
 Current income is not a consideration in selecting the Fund's investments.  The
 Fund may engage in options and futures transactions, foreign currency hedging
 transactions and securities lending.  The Fund may invest any portion of its
 assets in the securities of Canadian issuers and up to 20% of its assets in the
 securities of issuers headquartered outside the United States or Canada.  
 
 Loomis Sayles Mid-Cap Value Fund
 --------------------------------

    The Fund's objective is long-term capital growth from investments in common
 stocks or their equivalent.

    The Fund seeks to achieve  its objective by investing primarily in stocks
 with market capitalization between $500 million and $5 billion.  The Fund will
 normally maintain a median market capitalization between $1 billion and $5
 billion.  Loomis Sayles seeks to build a core portfolio of stocks that Loomis
 Sayles believes to be undervalued by the market in relation to the issuer's
 earnings, dividends, assets and growth prospects and that has a lesser emphasis
 on special situations and turnarounds (companies that have experienced
 significant business problems but that Loomis Sayles believes have favorable
 prospects for recovery).  Current income is not a consideration in selecting
 the Fund's investments.  The Fund may engage in options and futures
 transactions, foreign currency hedging transactions and securities lending.
 The Fund may invest any portion of its assets in the securities of Canadian
 issuers and up to 20% of its assets in the securities of issuers headquartered
 outside the United States or Canada.

 Loomis Sayles Mid-Cap Growth Fund
 ---------------------------------

    The Fund's investment objective is long-term capital growth from investments
 in common stocks or their equivalent.

    The Fund seeks to achieve its objective by investing primarily in stocks
 with market capitalization between $500 million and $5 billion.  The Fund will
 normally maintain a median market capitalization between $1 billion and $5
 billion. Stock selection will be driven by identifying the companies that are
 dominant in their markets, valuing each stock according to its appropriate
 growth phase and diversifying according to the risk characteristics of each
 phase.  Current income is not a consideration in selecting the Fund's
 investments.  The Fund may engage in options and futures transactions, foreign
 currency hedging transactions and securities lending.  The Fund may invest any
 portion of its assets in the securities of Canadian issuers and up to 20% of
 its assets in the securities of issuers headquartered outside the United States
 or Canada.

 Loomis Sayles Strategic Value Fund
 ----------------------------------

    The Fund's investment objective is long-term capital growth from investments
 in common stocks or their equivalent.

    The Fund seeks to achieve its objective by investing substantially all of
 its assets in common stocks or their equivalent that Loomis Sayles considers to
 be undervalued by the markets.  Stocks are selected based on a combination of
 quantitative factors including historical, relative price-earnings ratios;
 price-earnings ratios relative to growth rates; relative fundamentals and price
      
<PAGE>
 
     
 momentum; and qualitative factors including the quality of management, position
 in the industry, debt and balance sheet restructuring and product cycles.  The
 Fund's strategy is to have a relatively concentrated portfolio normally
 consisting of approximately 35-40 securities that Loomis Sayles considers best
 positioned to perform in the current and future environment. The Fund may
 engage in options and futures transactions, foreign currency hedging
 transactions and securities lending.  The Fund may invest any portion of it
 assets in the securities of Canadian issuers and up to 20% of its assets in the
 securities of issuers headquartered outside the United States or Canada.      

 All Funds

    Except for each Fund's investment objective, and any investment policies
 that are identified as "fundamental," all of the investment policies of each
 Fund may be changed without a vote of Fund shareholders.


                       MORE INFORMATION ABOUT THE FUNDS'
                                  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.
 Therefore, the value of an investment in a Fund that invests in equity
 securities may sometimes 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.

 Debt and Other Fixed Income Securities
 --------------------------------------

    The Worldwide Fund may invest in fixed income securities of any maturity.
 Fixed income securities pay a specified rate of interest or dividends, or a
 rate that is adjusted periodically by reference to some specified index or
 market rate.  Fixed income securities include securities issued by federal,
 state, local and foreign governments and related agencies, and by a wide range
 of private issuers.  Because interest rates vary, it is impossible to predict
 the income of a fund that invests in fixed income securities for any particular
 period.  The net asset value of such a fund's shares will vary as a result of
 changes in the value of the securities in the Fund's portfolio.

    Fixed income securities are subject to market and credit risk.  Market risk
 relates to changes in a security's value as a result of changes in interest
 rates generally.  In general, the values of fixed income securities increase
 when prevailing interest rates fall and decrease when interest rates rise.
 Credit risk relates to the ability of the issuer to make payments of principal
 and interest.

 Zero Coupon Securities
 ----------------------

    The Worldwide Fund may invest in "zero coupon" fixed income securities.
 These securities accrue interest at a specified rate, but do not pay interest
 in cash on a current basis.  A Fund investing in zero coupon securities is
 required to distribute the income on these securities to Fund shareholders as
 the income accrues, even though the Fund is not receiving the income in cash on
 a current basis.  Thus the Fund may have to sell other investments to obtain
 cash to make income distributions.  The market value of zero coupon securities
 is often more volatile than that of non-zero coupon fixed income securities of
 comparable quality and maturity.

 Collateralized Mortgage Obligations
 -----------------------------------

    The Worldwide Fund may invest in collateralized mortgage obligations
 ("CMOs").  A CMO is a security backed by a portfolio of mortgages or mortgage-
 backed securities held under an indenture.  CMOs may be issued either by U.S.
 Government instrumentalities or by non-governmental entities.  The issuer's
 obligation to make interest and principal payments is secured by the underlying
 portfolio of mortgages or mortgage-backed securities.  CMOs are issued with a
 number of classes or series which have different maturities and which may
 represent interests in some or all of the interest or principal on the
 underlying collateral or a combination thereof.  CMOs of different classes are
 generally retired in sequence as the underlying mortgage loans in the mortgage
 pool are repaid.  In the event of sufficient early prepayments on such
 mortgages, the class or series of CMOs first to mature generally will be
 retired prior to its maturity.  As with other mortgage-backed securities, the
 early retirement of a particular class or series of CMOs held by a Fund could
 involve the loss of any premium the Fund paid
<PAGE>
 
 when it acquired the investment and could result in the Fund's reinvesting the
 proceeds at a lower interest rate than the retired CMO paid.  Because of the
 early retirement feature, CMOs may be more volatile than many other fixed-
 income investments.

 When-Issued Securities
 ----------------------

    Each Fund may purchase securities on a "when-issued" basis.  This means that
 the Fund will 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 a 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 a Fund has outstanding obligations to buy when-issued
 securities, it will maintain liquid high-grade assets in a segregated account
 at its custodian bank in an amount sufficient to satisfy these obligations.

 Rule 144A Securities
 --------------------

      The Worldwide 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
 ------------------
        
    Each Fund may invest in securities of issuers organized or headquartered
 outside the United States ("foreign securities"). The Growth, Core Value and
 Small Cap Value Funds will not purchase a foreign security if, as a result, the
 Fund's holdings of foreign securities would exceed 20% of the Fund's total
 assets.  The Small Company Growth, Mid-Cap Value, Mid-Cap Growth and Strategic
 Value Funds may invest any portion of its assets in securities of Canadian
 issuers, but will not purchase other foreign securities if, as a result, the
 Funds' holding of non-U.S. and non-Canadian securities would exceed 20% of the
 Funds' total assets.      
 
    Although investing in foreign securities may increase a Fund's
 diversification and reduce portfolio volatility, 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
 government 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.  A 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.

    A Fund's investments in foreign securities may include investments in
 countries whose economies or securities markets are not yet 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 a Fund investing in these
 securities may be affected favorably or unfavorably by changes in currency
 exchange rates or exchange control regulations.  Changes in the value relative
 to the U.S. dollar of a foreign currency in which a 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.
<PAGE>
 
    In addition, although part of a 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
 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 a 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 a Fund's net income available for
 distribution to shareholders.

 Foreign Currency Hedging Transactions
 -------------------------------------

    Each Fund that invests in foreign securities 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 a 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, a Fund might purchase or sell a foreign
 currency on a spot (that is, cash) basis at the prevailing spot rate. If
 conditions warrant, the Funds may also enter into private contracts to purchase
 or sell foreign currencies at a future date ("forward contracts").  The Funds
 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 Funds may not be able to dispose of over-the-counter options readily.

    Foreign currency transactions involve costs and may result in losses.  In
 addition, each Fund's ability to engage in currency hedging transactions may be
 limited by tax considerations.

 Options and Futures Transactions
 --------------------------------
          
      The International Equity, Worldwide, Small Company Growth, Mid-Cap Value,
 Mid-Cap Growth and Strategic Value Funds may buy, sell or write options on
 securities, securities indexes, currencies or futures contracts. The Small
 Company Growth, Mid-Cap Value, Mid-Cap Growth and Strategic Value Funds may buy
 and sell futures contracts on securities, securities indexes or currencies. The
 Funds 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 Funds own or intend 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 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
 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 a 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
 Funds exceeds (or is less than) the price of the offsetting purchase, the Funds
 will realize a gain (or loss).

      The value of options purchased by the Funds and futures contracts held by
 the Funds may fluctuate up or down 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 a Funds' portfolio. All transactions in
 options and futures involve the possible risk of loss to the Funds of
<PAGE>
 
 all or a significant part of the value of its investment. In some cases, the
 risk of loss may exceed the amount of the Funds' investment. The Funds will be
 required, however, to set aside with its custodian bank certain assets in
 amounts sufficient at all times to satisfy its obligations under options,
 futures and contracts.

      The successful use of options and futures will usually depend on the
 ability to forecast stock market, currency or other financial market movements
 correctly. The Funds' 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 a Funds to close its
 positions on a timely basis. There can be no assurance that such a market will
 exist at any particular item. In the case of options that are not traded on an
 exchange ("over-the-counter" options), a Fund is at risk that the other party
 to the transaction will default on its obligations, or will not permit a Fund
 to terminate the transaction before its scheduled maturity. As a result of
 these characteristics, the Funds will treat most over-the-counter options (and
 the assets it segregates to cover its obligations thereunder) as illiquid.

      The options and futures markets of foreign countries are small compared to
 those of the United States and consequently are characterized in most cases by
 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.

 Securities Lending
 ------------------
          
      The Small Company, Mid-Cap Value, Mid-Cap Growth and Strategic Value Funds
 may lend their 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.

      The performance information presented in the graphs below relates to the
 institutional private accounts managed by the portfolio managers of the Small
 Company Growth Fund and the Strategic Value Fund that have investment
 objectives and policies substantially similar to those of the relevant Fund.
 The Funds are newly organized and have no performance record of their own.  The
 information below should not be considered a prediction of the future
 performance of any Fund.  The performance of the Funds may be higher or lower
 than the performance of a fund or account that has substantially similar
 investment objectives and policies.  The  performance information shown below
 for the accounts described below  is adjusted to give effect to the higher of
 the level of the actual expenses of the accounts during the periods shown or
 the annualized expenses projected for the relevant Fund's Retail Class shares
 during the first fiscal year.

 Small Company Growth Accounts
 -----------------------------

      Christopher R. Ely, Portfolio Manager of the Small Company Growth Fund,
 and Philip C. Fine and David L. Smith, Assistant Portfolio Managers of the
 Small Company Growth Fund, also serve, and have served, in those capacities for
 other accounts that have investment objectives and investment policies
 substantially similar to the Small Company Growth Fund (the "Small Company
 Growth Accounts").  Prior to July 22, 1996,  Messrs. Ely, Fine and Smith were
 affiliated with another advisory firm.  The following graph shows total returns
 for the one and two year periods ended September 30, 1996 for the Small Company
 Growth Accounts.   The information presented in footnote (2 ) below the graph
 represents the total return of the Keystone Institutional Small Cap Growth Fund
 and Keystone Small Company Growth Fund II, which have investment objectives and
 policies substantially similar to those of the Small Company Growth Fund and
 which, from their inception through July 11, 1996, were managed by Messrs. Ely,
 Fine and Smith in their capacities as employees of the firm with which they
 were then affiliated.  The performance information shown below is adjusted to
 give effect to the higher of the level of the actual expenses of the Accounts
 during the periods shown or the annualized expenses projected for the Fund's
 Retail Class shares during the first full fiscal year.

      A bar graph appears here, illustrating the one and two year annual returns
 for the periods ended September 30, 1996 for the Accounts (1)(2), the Russell
 2000 Index, the Russell 2000 Growth Index and the S&P 600 Index.  The data
 points from the chart are as follows:

 Russell 2000 Index                  %

 Russell 2000 Growth Index           %

 S&P 600 Index                       %

 (1)  The annual total return for the Accounts for the period June 29, 1994
 (inception of the Accounts) to September 30, 1996 was [ ]%.  The Accounts were
 managed by Messrs. Ely, Fine and Smith throughout the periods shown except for
 the period July 11, 1996 through September 16, 1996 when the management of the
 Accounts was in transition from the former adviser to Loomis Sayles.

 (2)  In the case of the Keystone Institutional Small Cap Growth Fund
 ("Institutional Fund"), the total return for the period January 1, 1996
 (inception of the Institutional Fund) to July 11, 1996 (the date that Messrs.
 Ely, Fine and Smith ceased management of the Institutional Fund)  was [ ]%.
 In the case of the Keystone Small Company Growth Fund II ("Fund II"), the total
 return for February 20, 1996,  the date of the Fund's inception, through July
 11, 1996 was [ ].  The information relating to Fund II does not take into
 account the sales charges of Fund II.  The lower total return of Fund II
 compared to the Institutional Fund and the Accounts is partially attributable
 to certain tax restrictions.

 Strategic Value Accounts
 ------------------------

      Philip J. Schettewi, portfolio manager of the Strategic Value Fund, also
 serves as portfolio manager for other accounts that have substantially the same
 investment objective and investment policies as the Strategic Value Fund  (the
 "Strategic Value Accounts") .  The following graph shows the total returns for
 the period from __________ through ____________ for the Strategic Value
 Accounts.  The graph also shows the total return of the Standard & Poor's/Barra
 Value Index for [each] [the same] periods.

      A bar graph appears here, illustrating the __, ___, ___ year total returns
 for ___________ to _______________ for the Strategic Value Accounts and the
 Standard & Poor's/Barra Value Index.

                                 FUND EXPENSES

    Each Fund pays Loomis Sayles a monthly investment advisory fee.  This fee is
 at the following annual percentage rate of the Fund's average daily net assets:
<TABLE>    
<CAPTION>
 
            Fund                      Fee Rate

            Strategic Value              .50
</TABLE>     
<PAGE>
 
    In addition to the investment advisory fee, each 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, expenses of preparing, printing and mailing
 prospectuses to existing shareholders and fees of trustees who are not
 directors, officers or employees of Loomis Sayles and its affiliated companies.
    
    Under a Distribution Plan adopted pursuant to Rule 12b-1 under the 1940 Act,
 each of the Funds pays 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 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 Funds, or for providing personal
 services to investors in Retail Class shares of the Funds 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 Funds. Loomis Sayles may pay certain broker-
 dealers or financial intermediaries whose customers are shareholders of the
 Funds a continuing fee in an amount of 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 Funds.      
    
    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 operating expenses of the Retail Class of shares of each Fund to
 1.50% of the Fund's average net assets.  Loomis Sayles may change or terminate
 these voluntary arrangements at any time, but the Funds' prospectus would be
 supplemented to describe the change and such Prospectus supplement would be
 mailed to shareholders 30 days before termination of the arrangements.      


                            PORTFOLIO TRANSACTIONS
    
    Portfolio turnover considerations will not limit Loomis Sayles' investment
 discretion in managing the Funds' assets. The Funds anticipate that their
 portfolio turnover rates will vary significantly from time to time depending on
 the volatility of economic and market conditions.  High portfolio turnover may
 involve higher costs and higher levels of taxable gains. Although it is not
 possible to predict the portfolio turnover rate with certainty, Loomis Sayles
 does not expect the Small Company Growth, Mid-Cap Value, Mid-Cap Growth and
 Strategic Value Funds' portfolio turnover rate to exceed _____%, _____%,
 _____%, and _____, respectively.      

    Loomis Sayles selects brokers and dealers to execute portfolio transactions
 for the Funds.  Subject to seeking best price and execution, Loomis Sayles may
 allocate these transactions to brokers or dealers whose customers have invested
 in the Trust.


                            HOW TO PURCHASE SHARES

    An investor may make an initial purchase of shares of any Fund by submitting
 a completed application form and payment to:
                        Boston Financial Data Services
                        P.O. Box 8314
                        Boston, Massachusetts  02266-8314
                        Attn: Loomis Sayles Funds
    
    The minimum investment for the Retail Class of each Fund's shares is
 $250,000 in that Fund. This investment minimum does not apply to purchases
 through certain financial intermediaries including, but not limited to, certain
 financial advisers, broker dealers, 401k alliances, wrap programs, no
 transaction fee programs, bank trust departments, financial consultants and
 insurance companies. The investment minimum will also be waived for
 shareholders who invest less than $250,000 but sign a letter of intent stating
 their intention to bring their balance to $250,000 in six months or less.
 Loomis Sayles reserves the right to redeem the accounts at net asset value of
 shareholders that have signed a letter of intent but fail to meet the
 investment minimum within the specified time. Subsequent investments must be at
 least $50.00.      
<PAGE>
 
    Shares of any Fund may be purchased by (i) cash, (ii) exchanging securities
 on deposit with a custodian acceptable to Loomis Sayles or (iii) a combination
 of such securities and cash.  Purchase of shares of the Fund in exchange for
 securities is subject in each case to the determination by Loomis Sayles that
 the securities to be exchanged are acceptable for purchase by the Fund.  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 which 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
 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.

    Loomis Sayles will not approve the acceptance of securities in exchange for
 shares of any 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 Fund shares by
 exchange of securities.

    All purchases made by check should be in U.S. dollars and made payable to
 the Loomis Sayles Funds or 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, Boston Financial Data Services, Inc.
 ("BFDS"), the shareholder servicing agent for State Street Bank and Trust
 Company ("State Street Bank"), opens an account, applies the payment to the
 purchase of full and fractional Fund shares and mails a statement of the
 account confirming 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 (Fund Name and
 Retail Class), DDA #9904-622-9, Shareholder Name, Shareholder Account Number."
 A bank may charge a fee for transmitting funds by wire.

    Each Fund reserves the right to reject any purchase order, including orders
 in connection with exchanges, for any reason which the Fund in its sole
 discretion deems appropriate. Although the Funds do not presently anticipate
 that they will do so, each 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 each Fund are sold with no sales charge.
 The net asset value of each 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 outstanding.  Portfolio securities are valued at their market value
 as more fully described in the Statement of Additional Information.

    Each Fund may accept telephone orders from broker-dealers who have been
 previously approved by the Fund.  It is the responsibility of such broker-
 dealers to promptly forward purchase or redemption orders to the Fund.
 Although there is no sales charge levied directly by the Fund, 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 or Loomis Sayles.
        
    Each Fund also offers an Institutional Class of shares that has a $1 million
 investment minimum and bears lower      
<PAGE>
 
 expenses. Because of its lower expenses, the Institutional Class of shares is
 expected to have a higher total return than the Retail Class of shares.


                             SHAREHOLDER SERVICES

    The Funds offer 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 the 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.  Shares of the Retail Class of any Fund may be
      -----------------------                                                
      exchanged for shares of the Retail Class of any other Fund or for shares
      of certain money market funds advised by New England Funds Management,
      L.P., an affiliate of Loomis Sayles.  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 for taking advantage of short-
      term swings in the market, and the Funds reserve the right to terminate or
      limit the privilege of any shareholder who makes more than 4 exchanges in
      any calendar year.  The Funds may terminate or change the terms of the
      exchange privilege at any time, upon 60 days' notice to shareholders.

      Retirement Plans.  The Retail Class of the Funds' 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 (this appears on
 an investor's confirmation statement) and should indicate any special capacity
 in which they are 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) 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, an investor must have his or her signature guaranteed by an
 eligible guarantor.  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.

    If an investor has requested certificates for the investment, an investor
 must enclose the certificates and a properly completed redemption form or stock
 power.  The Funds recommend that certificates be sent by registered mail.

    When an investor telephones a redemption request, the proceeds are wired to
 the bank account previously chosen by the investor.  A wire fee (currently
 $5.00) will be deducted from the proceeds.  A telephonic redemption request
 must be
<PAGE>
 
 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, an investor must send in this change on the Service Options Form with
 a signature guarantee.  Telephonic 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. 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 and Trust Company ("State Street").  BFDS will
 employ these or other reasonable procedures to confirm that instructions
 communicated by telephone are genuine; the Fund, State Street, BFDS 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
 information, 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 fifteen 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 which 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.


                DIVIDENDS, CAPITAL GAIN DISTRIBUTIONS AND TAXES

    The Funds declare and pay their net investment income to shareholders as
 dividends annually.  Each 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 Funds declare or pay
 dividends.

    Dividends and capital gain distributions will automatically be reinvested in
 additional shares of the same Fund on the record date unless an investor has
 elected to receive cash.

    Each Fund intends to qualify as a regulated investment company under the
 Internal Revenue Code of 1986, as amended.  As such, so long as a 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.

    Income dividends and short term capital gain distributions are taxable as
 ordinary income whether distributed in cash or additional shares.  Long-term
 capital gain distributions from all Funds are taxable as long-term capital
 gains whether distributed in cash or additional shares and regardless of how
 long an investor has owned shares of a Fund.

    Each 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.

    Certain designated dividends from the Funds  are expected to be eligible for
 the dividends-received deduction for corporate shareholders.
<PAGE>
 
    State Street Bank will send each investor and the IRS 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
        Funds. Before investing, an investor should consult his or her own tax
        adviser for more information concerning the federal, state and local tax
        consequences of investing in, redeeming or exchanging Fund shares.

                               SUMMARY OF EXPENSES

       The following information is provided to assist in understanding the
various expenses that an investor in a Fund will bear indirectly. The
information about each Fund shown below is based on annualized projected
expenses of the Retail Class of shares for the period from the Retail Class
commencement of operations through December 31, 1996. The information below
should not be considered a representation of past or future expenses, as actual
expenses may be greater or less than those shown. Also, the assumed 5% annual
return in the Example should not be considered a representation of investment
performance as actual performance will depend upon actual investment results of
securities held in the particular Fund's portfolio.

/1/  A $5 charge applies to any wire transfer of redemption proceeds from any
     Fund. A 2.00% redemption fee applies with respect to shares of the High
     Yield Fund redeemed within one (1) year of purchase. Loomis Sayles may, in
     its discretion, waive redemption fees on shares of the High Yield Fund as
     set forth under the heading "How to Redeem Shares" if it determines that
     there are minimal brokerage and transaction costs incurred in connection
     with the redemption. 
/2/  Loomis Sayles has voluntarily agreed, for an indefinite period, to limit
     these expenses to the percentages of net assets shown above. Without this
     agreement, annualized estimated total operating expenses for the fiscal
     period ended December 31, 1996 would have been _____% for the Bond Fund,
     _____% for the High Yield Fund, _____% for the Global Bond Fund, _____% for
     the Short-Term Bond Fund, _____% for the Investment Grade Bond Fund and
     _____% for the Intermediate Maturity Bond Fund.

       The Fund's investment objective is high total investment return through a
combination of current income and capital appreciation.

       The Fund seeks to achieve its objective by normally investing
substantially all of its assets in debt securities (including convertibles),
although up to 20% of its assets may be invested in preferred stocks. At least
65% of the Fund's total assets will normally be invested in bonds. The Fund may
invest any portion of its assets in securities of Canadian issuers, and 20% of
its assets in securities of other foreign issuers. The Fund will also invest
less than 35% of its assets in securities of below investment grade quality
(commonly known as "junk bonds").
    
       The Fund may invest in collateralized mortgage obligations ("CMOs") and
Rule 144A securities. The Fund may engage in foreign currency hedging and swap
transactions.     

       The percentages of the Fund's assets invested as of December 31, 1995 in
securities assigned to the various rating categories by Standard & Poor's Rating
Group ("Standard & Poor's") and Moody's Investors Services, Inc. ("Moody's")
were as follows: "AAA"/"Aaa" 13.2%; "AA"/"Aa" 9.2%; "A"/"A" 10.9%; "BBB"/"Baa"
32.3%; "BB"/"Ba" 12.0%; "B"/"B" 12.7%; "CCC"/"Caa" 9.7%.

  Loomis Sayles High Yield Fund
  -----------------------------

       The Fund's investment objective is high total investment return through a
combination of current income and capital appreciation.
    
       The Fund seeks to attain its objective by normally investing
substantially all of its assets in debt securities, although up to 20% of its
assets may be invested in preferred stocks and up to 10% of its assets may be
invested in common stocks. The Fund may also invest in convertible bonds,
when-issued securities, CMOs, options and Rule 144A securities. The Fund may
invest any portion of its assets in securities of Canadian issuers and up to 50%
of its assets in the securities of other foreign issuers. The Fund may engage in
foreign currency hedging and swap transactions.     

       The Fund will normally invest at least 65% of its assets in fixed income
securities of below investment grade quality (commonly referred to as "junk
bonds"), which are securities rated below BBB by Standard & Poor's or below Baa
by Moody's, including securities in the lowest rating categories, and unrated
securities that Loomis Sayles determines to be of comparable quality. See "More
Information about the Funds' Investments -- Lower Rated Fixed Income
Securities."

  Loomis Sayles Global Bond Fund
  ------------------------------

       The Fund's investment objective is high total investment return through a
combination of high current income and capital appreciation.

       The Fund seeks to achieve its objective by investing primarily in
investment grade fixed income obligations (including convertibles and CMOs)
denominated in various currencies, including U.S. dollars, or in multicurrency
units.

       Under normal conditions, the Fund will invest at least 65% of its total
assets in bonds of issuers from at least three countries which may include the
United States, and no more than 40% of its assets in issuers headquartered in
any one country. However, up to 100% of the Fund's assets may be denominated in
U.S. dollars. For temporary defensive purposes, the Fund may invest as much as
100% of its assets in debt securities, rated AAA by Standard & Poor's or Aaa by
Moody's at the time of purchase, of issuers from one or two countries, which may
include the United States.

                                                                               8

  Loomis Sayles Short-Term Bond Fund
  ----------------------------------

       The Fund's investment objective is high total investment return through a
combination of current income and capital appreciation with relatively low
fluctuation in net asset value.
    
       The Fund seeks to achieve its objective by normally investing
substantially all of its assets in debt securities (including convertibles and
CMOs), although up to 20% of its assets may be invested in non-convertible
preferred stock. At least 65% of the Fund's total assets will normally be
invested in bonds with a remaining maturity of 5 years or less. The Fund may
invest a limited portion of its assets in securities of foreign issuers. The
Fund may engage in foreign currency hedging and swap transactions.     

       In an effort to minimize fluctuations in market value, the Fund is
expected to maintain an average dollar-weighted maturity of between one and
three years.

  Loomis Sayles Investment Grade Bond Fund
  ----------------------------------------

       The Fund's investment objective is high total investment return through a
combination of capital appreciation and current income.
    
       The Fund seeks to achieve its objective by normally investing its assets
primarily in fixed income securities of investment grade quality although up to
20% of its assets may be invested in preferred stocks. Investment grade
securities include those rated BBB and above by Standard & Poor's and those
rated Baa and above by Moody's and unrated securities that Loomis Sayles
determines to be of comparable quality. The Fund may also invest up to 10% of
its assets in fixed income securities of below invest grade quality, including
securities in the lowest rating categories and unrated securities that Loomis
Sayles determines to be of comparable quality. The debt securities in which the
Fund may invest include corporate securities, U.S. Government securities,
commercial paper, zero coupon securities, mortgage-backed securities,
asset-backed securities, convertible bonds and when-issued securities. The Fund
may engage in options and futures transactions, repurchase transactions, foreign
currency hedging transactions and securities lending. The Fund may invest any
portion of its assets in the securities of Canadian issuers and up to 20% of its
assets in the securities of other foreign issuers. The Fund may engage in
foreign currency hedging and swap transactions.     
    
  Loomis Sayles Intermediate Maturity Bond Fund     
  ---------------------------------------------
    
       The Fund's investment objective is high total investment return through a
combination of current income and capital appreciation.     
    
       The Fund seeks to obtain its objective by normally investing at least 90%
of its assets in fixed income securities of investment grade quality with an
average dollar weighted maturity of between three and ten years. For purposes of
the 90% test, a security will be treated as being of investment grade quality if
it is rated by at least one major rating agency in one of its top four rating
categories at the time of purchase or, if unrated, is determined by Loomis
Sayles to be of comparable quality. The Fund may also invest up to 10% of its
assets in fixed income securities of below investment grade quality, which are
securities rated below BBB by Standard & Poor's and below Baa by Moody's and
unrated securities that Loomis Sayles believes are of comparable quality,
including securities in the lowest rating categories and unrated securities
determined by Loomis Sayles to be of comparable quality. The fixed income
securities in which the Fund may invest include corporate securities, U.S.
Government securities, commercial paper, zero coupon securities, mortgage-backed
securities, asset-backed securities, convertible bonds and when-issued
securities. The Fund may engage in options and future transactions, repurchase
transactions, foreign currency hedging transactions and securities lending. The
Fund may invest any portion of its assets in the securities of Canadian issuers
and up to 20% of its assets in securities of other foreign issuers. The Fund may
engage in foreign currency hedging and swap transactions.

                             AND RISK CONSIDERATIONS

  Debt and Other Fixed Income Securities
  --------------------------------------
    
       The Bond, High Yield, Global Bond, and Investment Grade Bond Funds may
all invest in fixed income securities of any maturity. Although the Short-Term
Bond Fund expects to maintain an average weighted maturity of less than three
years, individual portfolio holdings may have maturities longer than three
years. The Intermediate Maturity Bond Fund expects to maintain an average dollar
weighted maturity between three and ten years. Fixed income securities pay a
specified rate of interest or dividends, or a rate that is adjusted periodically
by reference to some specified index or market rate. Fixed income securities
include securities issued by federal, state, local and foreign governments and
related agencies, and by a wide range of private issuers. Because interest rates
vary, it is impossible to predict the income of a Fund that invests in fixed
income securities for any particular period. The net asset value of such a
Fund's shares will vary as a result of changes in the value of the securities in
the Fund's portfolio.     

       Fixed income securities are subject to market and credit risk. Market
risk relates to changes in a security's value as a result of changes in interest
rates generally. In general, the values of fixed income securities increase when
prevailing interest rates fall and decrease when interest rates rise. Credit
risk relates to the ability of the issuer to make payments of principal and
interest.

  U.S. Government Securities
  --------------------------

       U.S. Government Securities have different kinds of government support.
For example, some U.S. Government Securities, such as U.S. Treasury bonds, are
supported by the full faith and credit of the United States, whereas certain
other U.S. Government Securities issued or guaranteed by federal agencies or
government-sponsored enterprises are not supported by the full faith and credit
of the United States.

       Although U.S. Government Securities generally do not involve the credit
risks associated with other types of fixed income securities, the market values
of U.S. Government Securities do go up and down as interest rates change. Thus,
for example, the value of an investment in a Fund that holds U.S. Government
Securities may fall during times of rising interest rates. Yields on U.S.
Government Securities tend to be lower than those on corporate securities of
comparable maturities.

       Some U.S. Government Securities, such as Government National Mortgage
Association Certificates ("GNMA"), are known as "mortgage-backed" securities.
Interest and principal payments on the mortgages underlying mortgage-backed U.S.
Government Securities are passed through to the holders of the security. If a
Fund purchases mortgage-backed securities at a discount or a premium, the Fund
will recognize a gain or loss when the payments of principal, through prepayment
or otherwise, are passed through to the Fund and, if the payment occurs in a
period of falling interest rates, the Fund may not be able to reinvest the
payment at as favorable an interest rate. As a result of these principal
prepayment features, mortgage-backed securities are generally more volatile
investments than many other fixed income securities.

       In addition to investing directly in U.S. Government Securities, the
Funds may purchase certificates of accrual or similar instruments ("strips")
evidencing undivided ownership interests in interest payments or principal
payments, or both, in U.S. Government Securities. These investment instruments
may be highly volatile. For purposes of its policy of normally investing at
least 65% of its total assets in U.S. Government Securities, the U.S. Government
Securities Fund will not treat a strip as a U.S. Government Security unless the
strip itself is directly issued or guaranteed by the U.S. Government or an
agency, authority or instrumentality thereof.

  Lower Rated Fixed Income Securities
  -----------------------------------
    
       The Bond, High Yield, Global Bond, Short-Term Bond, Investment Grade Bond
and Intermediate Maturity Bond Funds may each invest a portion of its assets in
securities rated below investment grade (that is, below BBB or Baa and commonly
referred to as "junk bonds"), including securities in the lowest rating
categories, and comparable unrated securities. The Bond Fund may invest less
than 35%, the Global Bond and Short-Term Bond Funds each may invest up to     

                                                                              10
<PAGE>
 
    
20%, the Investment Grade Bond and Intermediate Maturity Bond Funds each may
invest up to 10% and the High Yield Fund will normally invest at least 65% of
its assets in such securities. For purposes of the foregoing percentages, a
security will be treated as being of investment grade quality if at the time a
Fund acquires it at least one major rating agency has rated the security in its
top four rating categories (even if another such agency has issued a lower
rating), or if the security is unrated but Loomis Sayles determines it to be of
investment grade quality. Lower rated fixed income securities generally provide
higher yields, but are subject to greater credit and market risk, than higher
quality fixed income securities. Lower rated fixed income securities are
considered predominantly speculative with respect to the ability of the issuer
to meet principal and interest payments. Achievement of the investment objective
of a Fund investing in lower rated fixed income securities may be more dependent
on the investment adviser's own credit analysis than is the case with higher
quality bonds. The market for lower rated fixed income securities may be more
severely affected than some other financial markets by economic recession or
substantial interest rate increases, by changing public perceptions of this
market or by legislation that limits the ability of certain categories of
financial institutions to invest in these securities. In addition, the secondary
market may be less liquid for lower rated fixed income securities. This lack of
liquidity at certain times may affect the values of these securities and may
make the valuation and sale of these securities more difficult. Securities in
the lowest rating categories may be in poor standing or in default. Securities
in the lowest investment grade category (BBB or Baa) have some speculative
characteristics.

- ----------------------------------------------------------------------------
rating categories, see Appendix A.
- ----------------------------------

  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.
Therefore, the value of an investment in a Fund that invests in equity
securities may sometimes 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.

  Zero Coupon Securities
  ----------------------

       The Funds may each invest in "zero coupon" fixed income securities. These
securities accrue interest at a specified rate, but do not pay interest in cash
on a current basis. A Fund investing in zero coupon securities is required to
distribute the income on these securities to Fund shareholders as the income
accrues, even though the Fund is not receiving the income in cash on a current
basis. Thus the Fund may have to sell other investments to obtain cash to make
income distributions. The market value of zero coupon securities is often more
volatile than that of non-zero coupon fixed income securities of comparable
quality and maturity.

  Mortgage-Backed Securities
  --------------------------

       All of the Funds may invest in mortgage-backed securities, such as GNMA
or Federal National Mortgage Association certificates, which differ from
traditional debt securities . Among the major differences are that interest and
principal payments are made more frequently, usually monthly, and that principal
may be prepaid at any time because the underlying mortgage loans generally may
be prepaid at any time. As a result, if a Fund purchases these assets at a
premium, a faster-than-expected prepayment rate will reduce yield to maturity,
and a slower-than-expected prepayment rate will have the opposite effect of
increasing yield to maturity. If a Fund purchases mortgage-backed securities at
a discount, faster- than-expected prepayments will increase, and
slower-than-expected prepayments will reduce, yield to maturity. Prepayments,
and resulting amounts available for reinvestment by the Fund, are likely to be
greater during period of declining interest rates and, as a result, are likely
to be reinvested at lower interest rates. Accelerated prepayments on securities
purchased at a premium may result in a loss of principal if the premium has not
been fully amortized at the time of prepayment. Although these securities will
decrease in value as a result of increases in interest rates generally, they are
likely to appreciate less than other fixed-income securities when interest rates
decline because of the risk of prepayments.

  Collateralized Mortgage Obligations
  -----------------------------------
    
       The Bond, High Yield, Global Bond, Short-Term Bond, Investment Grade and
Intermediate Maturity Bond Funds each may invest in CMOs. A CMO is a security
backed by a portfolio of mortgages or mortgage-backed securities held under an
indenture. CMOs may be issued either by U.S. Government instrumentalities or by
non-governmental entities. The issuer's obligation to make interest and
principal payments is secured by the underlying portfolio of mortgages or     

                                                                              11
<PAGE>
 
    
mortgage-backed securities. CMOs are issued with a number of classes or series
which have different maturities and which may represent interests in some or all
of the interest or principal on the underlying collateral or a combination
thereof. CMOs of different classes are generally retired in sequence as the
underlying mortgage loans in the mortgage pool are repaid. In the event of
sufficient early prepayments on such mortgages, the class or series of CMOs
first to mature generally will be retired prior to its maturity. As with other
mortgage-backed securities, the early retirement of a particular class or series
of CMOs held by a Fund could involve the loss of any premium the Fund paid when
it acquired the investment and could result in the Fund's reinvesting the
proceeds at a lower interest rate than the retired CMO paid. Because of the
early retirement feature, CMOs may be more volatile than many other fixed-income
investments.     

  Asset-Backed Securities
  -----------------------

       All of the Funds may invest in asset-backed securities. Through the use
of trusts and special purpose corporations, automobile and credit card
receivables are securitized in pass-through structures similar to mortgage
past-through structures or in a pay-through structure similar to the CMO
structure. Generally, the issuers of asset-backed bonds, notes or pass-through
certificates are special purpose entities and do not have any significant assets
other than the receivables securing such obligations. In general, the collateral
supporting asset-backed securities is of shorter maturity than mortgage loans.
Instruments backed by pools of receivables are similar to mortgage-backed
securities in that they are subject to unscheduled prepayments of principal
prior to maturity. When the obligations are prepaid, the Fund will ordinarily
reinvest the prepaid amounts in securities the yields of which reflect interest
rates prevailing at the time. Therefore, a Fund's ability to maintain a
portfolio that includes high-yielding asset-backed securities will be adversely
affected to the extent that prepayments of principal must be reinvested in
securities that have lower yields than the prepaid obligations. Moreover,
prepayments of securities purchased at a premium could result in a realized
loss.

  When-Issued Securities
  ----------------------

       Each Fund may purchase securities on a "when-issued" basis. This means
that the Fund will 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 a 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 a Fund has outstanding obligations to buy when-issued
securities, it will maintain liquid high-grade assets in a segregated account at
its custodian bank in an amount sufficient to satisfy these obligations.

  Rule 144A Securities
  --------------------
    
       The High Yield and Bond Funds 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
  ------------------
    
       Each Fund may invest in securities of issuers organized or headquartered
outside the United States ("foreign securities"). The Short-Term Bond Fund will
not purchase a foreign security if, as a result, the Fund's holdings of foreign
securities would exceed 20% of the Fund's total assets. The Bond, Investment
Grade Bond, and Intermediate Maturity Bond Funds may invest any portion of its
assets in securities of Canadian issuers, but will not purchase other foreign
securities 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. The High Yield Fund may
invest any portion of its assets in securities of Canadian issuers and up to 50%
of its assets in the securities of other foreign issuers.     

       Although investing in foreign securities may increase a Fund's
diversification and reduce portfolio volatility, foreign securities may present
risks not associated with investments in comparable securities of U.S. issuers.
There may be less

                                                                              12
<PAGE>
 
information publicly available about a foreign corporate or government 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. A 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.

       A Fund's investments in foreign securities may include investments in
countries whose economies or securities markets are not yet 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 a Fund investing in these
securities may be affected favorably or unfavorably by changes in currency
exchange rates or exchange control regulations. Changes in the value relative to
the U.S. dollar of a foreign currency in which a 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 a 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
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 Bond, High Yield, Global
Bond, Investment Grade Bond, Intermediate Maturity Funds 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 a Fund's net income available for
distribution to shareholders.

  Foreign Currency Hedging Transactions
  -------------------------------------

       The Funds may engage in foreign currency exchange transactions 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 a 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, a Fund might purchase or sell a foreign currency on a spot (that is,
cash) basis at the prevailing spot rate. If conditions warrant, the Funds may
also enter into private contracts to purchase or sell foreign currencies at a
future date ("forward contracts"). The Funds 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 Funds may not be able to
dispose of over-the-counter options readily.

       Foreign currency transactions involve costs and may result in losses. In
addition, each Fund's ability to engage in currency hedging transactions may be
limited by tax considerations.

  Swaps
  -----
    
       The Funds may enter into interest rate or currency swaps. The Funds will
  enter into these transactions primarily to preserve a return or spread on a
  particular investment or portion of its portfolio, to protect against currency
  fluctuations, as a duration management technique or to protect against any
  increase in the price of securities a Fund anticipates purchasing     

                                                                              13
<PAGE>
 
    
  at a later date. Interest rate swaps involve the exchange by a Fund with
  another party of their respective commitments to pay or receive interest (for
  example, an exchange of floating rate payments for fixed rate payments with
  respect to a notional amount of principal.) A currency swap is an agreement to
  exchange cash flows on a notional amount based on changes in the relative
  values of the specified currencies. The fund will maintain liquid assets in a
  segregated custodial account to cover its current obligations under swap
  agreements. Because swap agreements are not exchange-traded, but are private
  contracts into which the Fund and a swap counterparty enter as principals, the
  Fund may experience a loss or delay in recovering assets if the counterparty
  were to default on its obligations.     

  Options and Futures Transactions
  --------------------------------

       The Funds may buy, sell or write options on securities, securities
indexes, currencies or futures contracts and may buy and sell futures contracts
on securities, securities indexes or currencies. The Funds 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 Funds own or intend 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 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
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 a 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 Funds exceeds
(or is less than) the price of the offsetting purchase, the Funds will realize a
gain (or loss).

       The value of options purchased by the Funds and futures contracts held by
the Funds may fluctuate up or down 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 a Funds' portfolio. All transactions in options
and futures involve the possible risk of loss to the Funds 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 Funds' investment. The Funds will be required,
however, to set aside with its custodian bank certain assets in amounts
sufficient at all times to satisfy its obligations under options, futures and
contracts.

       The successful use of options and futures will usually depend on the
ability to forecast stock market, currency or other financial market movements
correctly. The Funds' 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 a Funds to close its positions on a timely
basis. There can be no assurance that such a market will exist at any particular
item. In the case of options that are not traded on an exchange
("over-the-counter" options), a Fund is at risk that the other party to the
transaction will default on its obligations, or will not permit a Fund to
terminate the transaction before its scheduled maturity. As a result of these
characteristics, the Funds will treat most over-the-counter options (and the
assets it segregates to cover its obligations thereunder) as illiquid.

       The options and futures markets of foreign countries are small compared
to those of the United States and consequently are characterized in most cases
by 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.

                                                                              14

  Repurchase Agreements
  ---------------------
    
       Each Fund may invest in repurchase agreements. In repurchase agreements,
a 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 a Fund to earn a
return on available cash at minimal market risk, although the Series may be
subject to various delays and risks of loss if the seller is unable to meet its
obligations to repurchase.     

  Securities Lending
  ------------------

       The Investment Grade Bond and Intermediate Maturity Bond Funds may lend
their 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 331/3% 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.

                                 FUND EXPENSES

       Each Fund pays Loomis Sayles a monthly investment advisory fee. This fee
is at the following annual percentage rate of the Fund's average daily net
assets:

<TABLE>
<CAPTION>

            Fund                                             Fee Rate
            ----                                             --------
            <S>                                              <C>     
            Bond                                                 .60
            High Yield                                           .60
            Global Bond                                          .60
            Short-Term Bond                                      .25
            Investment Grade Bond                                .40
            Intermediate Maturity Bond                           .40
</TABLE>

       In addition to the investment advisory fee, each 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, 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.

       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 Fund total annual operating expenses to 1.00% of the average net assets of
the High Yield and Bond Funds, to .75% of the average net assets of the Short
Term Bond Fund, to 1.50% of the average net assets of the Global Bond Fund, and
to .80% of the average net assets of the Investment Grade Bond and the
Intermediate Grade Bond Funds. Under a Distribution Plan adopted pursuant to
Rule 12b-1 under the 1940 Act, each of the Funds pays the Distributor, a
subsidiary of Loomis Sayles, a monthly distribution fee at an annual a rate not
to exceed 0.25% of the Fund's average net assets attributable to the Retail
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 Funds, or
for providing personal services to investors in Retail Class shares of the Funds
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 Funds.

       Loomis Sayles may pay certain broker-dealers and financial intermediaries
whose customers own shares of the Funds a continuing fee in an amount of 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 Funds.

                             PORTFOLIO TRANSACTIONS

       Portfolio turnover considerations will not limit Loomis Sayles'
investment discretion in managing the Funds' assets. The Funds anticipate that
their portfolio turnover rates will vary significantly from time to time
depending on the volatility of economic and market conditions. High portfolio
turnover may involve higher costs and higher levels of taxable gains.

                                                                              17
<PAGE>
 
    
Although it is not possible to predict the portfolio turnover rate with
certainty, Loomis Sayles does not expect the portfolio turnover rate of the High
Yield, Investment Grade Bond and Intermediate Grade Bond Funds to exceed 60%,
_____%, and _____%, respectively.     

       Loomis Sayles selects brokers and dealers to execute portfolio
transactions for the Funds. Subject to seeking best price and execution, Loomis
Sayles may allocate these transactions to brokers or dealers whose customers
have invested in the Trust.

                             HOW TO PURCHASE SHARES

       An investor may make an initial purchase of shares of any Fund by
submitting a completed application form and payment to:

                         Boston Financial Data Services
                         P.O. Box 8314
                         Boston, Massachusetts 02266-8314
                         Attn: Loomis Sayles Funds
    
       The minimum investment for retail class of the Funds' shares ("Retail
Shares") is $250,000 in that Fund. This investment minimum does not apply to
purchases through financial intermediaries including, but not limited to,
certain financial advisers, broker dealers, 401k alliances, wrap programs, no
transaction fee programs, bank trust departments, financial consultants and
insurance companies. The investment minimum will also be waived for shareholders
who invest less than $250,000 but sign a letter of intent stating their
intention to bring their balance to $250,000 in six months or less. Loomis
Sayles reserves the right to redeem, at net asset value, the accounts of
shareholders that have signed a letter of intent but fail to meet the investment
minimum within the specified time. Subsequent investments must be at least
$50.00.     

       Shares of any Fund may be purchased by (i) cash, (ii) exchanging
securities on deposit with a custodian acceptable to Loomis Sayles or (iii) a
combination of such securities and cash. Loomis Sayles will not approve the
acceptance of securities in exchange for shares of any 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 Fund shares 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 which 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 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 1-800-633-3330.

       All purchases made by check should be in U.S. dollars and made payable to
the Loomis Sayles Funds or State Street Bond 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, Boston Financial Data Services,
Inc. ("BFDS"), the shareholder servicing agent for State Street Bank and Trust
Company ("State Street Bank"), opens an account, applies the payment to the
purchase of full and fractional Fund shares and mails a statement of the account
confirming 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.

                                                                              18
<PAGE>
 
       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 (Fund Name and Retail Class),
DDA #9904-622-9, Shareholder Name, Shareholder Account Number." A bank may
charge a fee for transmitting funds by wire.

       Each Fund reserves the right to reject any purchase order, including
orders in connection with exchanges, for any reason which the Fund in its sole
discretion deems appropriate. Although the Funds do not presently anticipate
that they will do so, each 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 each Fund are sold with no sales charge.
The net asset value of each 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
outstanding. Portfolio securities are valued at their market value as more fully
described in the Statement of Additional Information.

       Each Fund may accept telephone orders from broker-dealers who have been
previously approved by the Fund. It is the responsibility of such broker-dealers
to promptly forward purchase or redemption orders to the Fund. Although there is
no sales charge levied directly by the Fund, 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 or Loomis Sayles.

       Each Fund also offers an Institutional Class of shares that has a $1
million investment minimum and bears lower expenses. Because of its lower
expenses, the Institutional Class of shares is expected to have a higher total
return than the Retail Class of shares.

                              SHAREHOLDER SERVICES

       The Funds offer 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 the 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. Shares of the Retail Class of any Fund may be
          -----------------------
          exchanged for shares of the Retail Class of any other Fund or for
          shares of certain money market funds advised by New England Funds
          Management, L.P., an affiliate of Loomis Sayles. 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 for taking advantage of
          short-term swings in the market, and the Funds reserve the right to
          terminate or limit the privilege of any shareholder who makes more
          than 4 exchanges in any calendar year. The Funds may terminate or
          change the terms of the exchange privilege at any time, upon 60 days'
          notice to shareholders. Exchanges of shares of the High Yield Fund
          purchased within one year of such exchanges will be subject to a
          redemption fee of 2.00% of the amount exchanged. For purposes of
          determining whether a redemption fee is payable with respect to shares
          of the High Yield Fund purchased by exchange of shares of another
          Fund, the one year period shall be deemed to begin on the date of such
          purchase by exchange.     

          Retirement Plans. The Institutional Class of the Funds' 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.

                                                                              19
<PAGE>
 
          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.
Proceeds from a written request may be sent to the investor in the form of a
check. As described below, an investor may also redeem shares by calling BFDS at
800-626-9390. Proceeds resulting from a 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 (this appears
on an investor's confirmation statement) and should indicate any special
capacity in which they are signing (such as trustee or custodian or on behalf of
a partnership, corporation or other entity). Shareholders 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) 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, an investor must have his or her signature guaranteed by an
eligible guarantor. 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.

       If an investor has requested certificates for the investment, an investor
must enclose the certificates and a properly completed redemption form or stock
power. The Funds recommend that certificates be sent by registered mail.

       When an investor telephones a redemption request, the proceeds are wired
to the bank account previously chosen by the investor. A wire fee (currently
$5.00) 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, an investor must send in this change on the Service Options Form
with a signature guarantee. Telephonic 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. 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 and Trust Company ("State Street"). BFDS will employ these or
other reasonable procedures to confirm that instructions communicated by
telephone are genuine; the Fund, State Street, BFDS 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 information, 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, 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
Fund purchased within one (1) year of such redemption. Loomis Sayles, in its
discretion, may waive the 2.00% redemption fee with respect to shares of the
High Yield Fund.     

                                                                              20

       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 fifteen 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 which 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.

                 DIVIDENDS, CAPITAL GAIN DISTRIBUTIONS AND TAXES

       The Global Bond Fund declares and pays its net investment income to
shareholders as dividends annually; the Bond, High Yield, Investment Grade Bond,
Intermediate Maturity Bond Funds declare and pay dividends [monthly]; the Short-
Term Bond Fund declares dividends daily and make payments monthly. Each 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 Funds declare or pay dividends.

       Dividends and capital gain distributions will automatically be reinvested
in additional shares of the same Fund on the record date unless an investor has
elected to receive cash.

       Each Fund intends to qualify as a regulated investment company under the
Internal Revenue Code of 1986, as amended. As such, so long as a 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
are taxable as ordinary income whether distributed in cash or additional shares.
Long-term capital gain distributions from all Funds are taxable as long-term
capital gains whether distributed in cash or additional shares and regardless of
how long an investor has owned shares of the Fund.

       Each 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 (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 he or she is not subject to such withholding.

       Dividends derived from interest on U.S. Government securities may be
exempt from state and local taxes.

       State Street Bank will send investors and the IRS an annual statement
detailing federal tax information, including information about dividends and
distributions paid during the preceding year. An investor should keep this
statement as a permanent record. A fee may be charged for any duplicate
information requested.

NOTE:       The foregoing summarizes certain tax consequences of investing in
            the Funds. Before investing, an investor should consult his or her
            own tax adviser for more information concerning the federal, state
            and local tax consequences of investing in, redeeming or exchanging
            Fund shares.

                                                                              21

                                   APPENDIX A

                     DESCRIPTION OF BOND RATINGS ASSIGNED BY
                              STANDARD & POOR'S AND
                         MOODY'S INVESTORS SERVICE, INC.

  STANDARD & POOR'S
  -----------------

                                       AAA

  This is the highest rating assigned by Standard & Poor's to a debt obligation
  and indicates an extremely strong capacity to pay interest and repay
  principal.

                                       AA

  Bonds rated AA also qualify as high quality debt obligations. Capacity to pay
  interest and repay principal is very strong, and in the majority of instances
  they differ from AAA issues only in small degree.

                                        A

  Bonds rated A have a strong capacity to pay interest and repay principal,
  although they are somewhat more susceptible to the adverse effects of changes
  in circumstances and economic conditions.

                                       BBB

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

                                 BB, B, CCC, CC

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

                                        C

  The rating C is reserved for income bonds on which no interest is being paid.

                                        D

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

  Plus (+) or Minus (-): The ratings from "AA" to "B" may be modified by the
  addition of a plus or minus sign to show relative standing within the major
  rating categories.

                                       A-1

  MOODY'S INVESTORS SERVICE, INC.
  -------------------------------

                                       Aaa

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

                                       Aa

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

                                        A

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

                                       Baa

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

                                       Ba

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

                                        B

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

                                       Caa

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

                                       Ca

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

                                        C

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

                                       A-2
<PAGE>
 
  Should no rating be assigned by Moody's, the reason may be one of the
  following:

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

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

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

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

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

  Note:   Those bonds in the Aa, A, Baa, Ba and B groups which Moody's believes
          possess the strongest investment attributes are designated by the
          symbols Aa1, A1, Baa1, Ba1 and B1.

                                    SUMMARY OF EXPENSES
    
  The following information is provided to assist an investor in understanding
the various expenses that an investor in a Fund will bear indirectly.  Except in
the case of the Worldwide, Small Company Growth, Mid-Cap Value, Mid-Cap Growth
and Strategic Value Funds, the information is based on expenses of the
Institutional Class shares for the Funds' fiscal year ended December 31, 1995.
The Worldwide, Small Company Growth, Mid-Cap Value, Mid-Cap Growth and Strategic
Value Funds did not commence operations until 1996; the information about each
shown below is based on annualized projected expenses of the Institutional Class
shares for the period from the Fund's commencement of operations through
December 31, 1996.  The information below should not be considered a
representation of past or future expenses, as actual expenses may be greater or
less than those shown.  Also, the assumed 5% annual return in the Example should
not be considered a representation of investment performance as actual
performance will depend upon actual investment results of securities held in the
particular Fund's portfolio.

 /1/     A $5 charge applies to any wire transfer of redemption proceeds from
         any Fund.
 /2/     The management fees shown in the table have been restated to reflect 
         a reduction in the management fees payable to Loomis Sayles.
         Actual management fees for the fiscal year ended December 31, 1995    
         were _____% for the Growth Fund, _____% for the Core Value Fund, 
         _____% for the Small Cap Value Fund, _____% for the International 
         Equity Fund and _____% for the Worldwide Fund.
 /3/     Loomis Sayles has voluntarily agreed, for an indefinite period, to
         limit these Funds' total operating expenses to the percentages
         of net assets shown above. Without this agreement, estimated      
         Total Operating Expenses would have been 2.55% for the Worldwide 
         Fund, _______% for the Small Company Growth Fund, _______% for the 
         Mid-Cap Value Fund, _______% for the Mid-Cap Growth Fund and 
         _______% for the Strategic Value Fund. Actual Total Operating Expenses 
         for the fiscal year ended December 31, 1995 were 1.08% for the Growth
         Fund, 1.20% for the Core Value Fund, 1.25% for the Small Cap Value 
         Fund and 1.45% for the International Equity Fund.

                                   THE TRUST

  Each 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.  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
    
Loomis Sayles Core Value Fund     
- -----------------------------

  The Fund's investment objective is long-term growth of capital and income.

  The Fund seeks to achieve its objective by investing substantially all of its
assets in common stocks or their equivalent which Loomis Sayles considers to be
undervalued in relation to the issuer's earnings, dividends, assets and growth
prospects.  The Fund may invest a limited portion of its assets in securities of
foreign issuers.

Loomis Sayles Growth Fund
- -------------------------

  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. Investments are selected based on
their growth potential; current income is not a consideration.  The Fund may
invest in companies with relatively small market capitalization, as well as in
larger companies.  The Fund may invest a limited portion of its assets in
securities of foreign issuers.

Loomis Sayles International Equity Fund
- ---------------------------------------

  The Fund's investment objective is high total investment return through a
combination of capital appreciation and current income.

  The Fund seeks to achieve its objective by investing primarily in equity
securities of companies organized or headquartered outside the United States.
Under normal conditions the Fund will invest at least 65% of its total assets in
equity securities of issuers of at least three countries outside the United
States, and no more than 20% of its assets in issuers headquartered in any one
country.  For temporary defensive purposes, the Fund may invest as much as 100%
of its assets in issuers from one or two countries, which may include the United
States.
    
Loomis Sayles Mid-Cap Value Fund
- --------------------------------

  The Fund's objective is long-term capital growth from investments in common
stocks or their equivalent.

  The Fund seeks to achieve its objective by investing primarily in stocks with
market capitalization between $500 million and $5 billion.  The Fund will
normally maintain a median market capitalization between $1 billion and $5
billion. Loomis Sayles seeks to build a core portfolio of stocks that Loomis
Sayles believes to be undervalued by the market in relation to the issuer's
earnings, dividends, assets and growth prospects and that has a lesser emphasis
on special situations and turnarounds (companies that have experienced
significant business problems but that Loomis Sayles believes have favorable
prospects for recovery).  Current income is not a consideration in selecting the
Fund's investments.  The Fund may engage in options and futures transactions,
foreign currency hedging transactions and securities lending.  The Fund may
invest any portion of its assets in the securities of Canadian issuers and up to
20% of its assets in the securities of issuers headquartered outside the United
States or Canada.

Loomis Sayles Mid-Cap Growth Fund
- ---------------------------------

  The Fund's investment objective is long-term capital growth from investments
in common stocks or their equivalent.     

                                                                               9
<PAGE>
 
    
  The Fund seeks to achieve its objective by investing primarily in stocks with
market capitalization between $500 million and $5 billion.  The Fund will
normally maintain a median market capitalization between $1 billion and $5
billion. Stock selection will be driven by identifying the companies that are
dominant in their markets, valuing each stock according to its appropriate
growth phase and diversifying according to the risk characteristics of each
phase.  Current income is not a consideration in selecting the Fund's
investments.  The Fund may engage in options and futures transactions, foreign
currency hedging transactions and securities lending.  The Fund may invest any
portion of its assets in the securities of Canadian issuers and up to 20% of its
assets in the securities of issuers headquartered outside the United States or
Canada.

Loomis Sayles Small Cap Value Fund     
- ----------------------------------

  The Fund's investment objective is long-term capital growth from investments
in common stocks or their equivalent.

  The Fund seeks to achieve its objective by investing primarily in stocks of
small cap companies with good earnings growth potential that Loomis Sayles
believes are undervalued by the market.  The Fund will normally invest at least
65% of its total assets in companies with market capitalization of less than $1
billion and may invest up to 35% of its assets in larger companies.  Loomis
Sayles seeks to build a core small cap portfolio of stocks of solid companies
with reasonable growth prospects and that are attractively priced in relation to
the companies' earnings with a smaller emphasis on special situations and
turnarounds (companies that have experienced significant business problems but
which Loomis Sayles believes have favorable prospects for recovery), as well as
unrecognized stocks.  The Fund may invest a limited portion of its assets in
securities of foreign issuers. Current income is not a consideration in
selecting the Fund's investments.
    
Loomis Sayles Small Company Growth Fund
- ---------------------------------------

  The Fund's investment objective is long-term capital growth from investments
in common stocks or their equivalent.

  The Fund seeks to achieve its objective by investing primarily in stocks of
small, rapidly growing companies that Loomis Sayles believes have the potential
for accelerating earnings growth and rising profit margins.  The Fund will
normally invest at least 65% of its total assets in companies with market
capitalization of less than $1 billion and may invest up to 35% of its total
assets in larger companies.  Loomis Sayles seeks companies that have distinctive
products, technologies, or services; dynamic earnings growth; prospects for a
high level of profitability; and outstanding management.  Current income is not
a consideration in selecting the Fund's investments.  The Fund may engage in
options and futures transactions, foreign currency hedging transactions and
securities lending.  The Fund may invest any portion of its assets in the
securities of Canadian issuers and up to 20% of its assets in the securities of
issuers headquartered outside the United States or Canada.     

Loomis Sayles Strategic Value Fund
- ----------------------------------

  The Fund's investment objective is long-term capital growth from investments
in common stocks or their equivalent.

  The Fund seeks to achieve its objective by investing substantially all of its
assets in common stocks or their equivalent that Loomis Sayles considers to be
undervalued by the markets.  Stocks are selected based on a combination of
quantitative factors including historical, relative price-earnings ratios;
price-earnings ratios relative to growth rate; relative fundamentals and price
momentum; and qualitative factors including the quality of management, position
in the industry, debt and balance sheet restructuring and product cycles.  The
Fund's strategy is to have a relatively concentrated portfolio normally
consisting of approximately 35-40 securities that Loomis Sayles considers best
positioned to perform in the current and future environment.  The Fund may
engage in options and futures transactions, foreign currency hedging
transactions and securities lending.  The Fund may invest any portion of it
assets in the securities of Canadian issuers and up to 20% of its assets in 
the securities of issuers headquartered outside the United States or Canada.

Loomis Sayles Worldwide Fund
- ----------------------------

  The Fund's investment objective is high total investment return through a
combination of capital appreciation and current income.

  The Fund seeks to achieve its objective by investing in U.S. and foreign
equity and debt securities.  The allocation of the Fund's assets among the four
sectors of domestic equities, international equities, domestic bonds and
international bonds will be made by Loomis Sayles' Global Asset Allocation
Group.  The Fund will normally invest its assets in

                                                                              10
<PAGE>
 
securities of issuers from at least three countries, one of which will be the
United States.  The Fund may invest less than 35% of its assets in fixed income
securities of below investment grade quality (commonly referred to as "junk
bonds"). The Fund may also invest in collateralized mortgage obligations
("CMOs") and Rule 144A securities.  See "More information about the Funds'
Investments" below.

  The Fund may engage in options and forward contract transactions to hedge
against changes in the value of securities and the currencies in which they are
denominated.

All Funds

  Except for each Fund's investment objective, and any investment policies that
are identified as "fundamental," all of the investment policies of each Fund may
be changed without a vote of Fund shareholders.


                 MORE INFORMATION ABOUT THE FUNDS' 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.
Therefore, the value of an investment in a Fund that invests in equity
securities may sometimes 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.

Debt and Other Fixed Income Securities
- --------------------------------------

    The Worldwide Fund may invest in fixed income securities of any maturity.
Fixed income securities pay a specified rate of interest or dividends, or a rate
that is adjusted periodically by reference to some specified index or market
rate. Fixed income securities include securities issued by federal, state, local
and foreign governments and related agencies, and by a wide range of private
issuers.  Because interest rates vary, it is impossible to predict the income of
a fund that invests in fixed income securities for any particular period.  The
net asset value of such a fund's shares will vary as a result of changes in the
value of the securities in the Fund's portfolio.

  Fixed income securities are subject to market and credit risk.  Market risk
relates to changes in a security's value as a result of changes in interest
rates generally.  In general, the values of fixed income securities increase
when prevailing interest rates fall and decrease when interest rates rise.
Credit risk relates to the ability of the issuer to make payments of principal
and interest.

Zero Coupon Securities
- ----------------------

  The Worldwide Fund may invest in "zero coupon" fixed income securities.  These
securities accrue interest at a specified rate, but do not pay interest in cash
on a current basis.  A Fund investing in zero coupon securities is required to
distribute the income on these securities to Fund shareholders as the income
accrues, even though the Fund is not receiving the income in cash on a current
basis.  Thus the Fund may have to sell other investments to obtain cash to make
income distributions.  The market value of zero coupon securities is often more
volatile than that of non-zero coupon fixed income securities of comparable
quality and maturity.

Collateralized Mortgage Obligations
- -----------------------------------

  The Worldwide Fund may invest in collateralized mortgage obligations ("CMOs").
A CMO is a security backed by a portfolio of mortgages or mortgage-backed
securities held under an indenture.  CMOs may be issued either by U.S.
Government instrumentalities or by non-governmental entities.  The issuer's
obligation to make interest and principal payments is secured by the underlying
portfolio of mortgages or mortgage-backed securities.  CMOs are issued with a
number of classes or series which have different maturities and which may
represent interests in some or all of the interest or principal on the
underlying collateral or a combination thereof.  CMOs of different classes are
generally retired in sequence as the underlying mortgage loans in the mortgage
pool are repaid.  In the event of sufficient early prepayments on such
mortgages, the class or series of CMOs first to mature generally will be retired
prior to its maturity.  As with other mortgage-backed securities, the early
retirement of a particular class or series of CMOs held by a Fund could involve

<PAGE>
 
the loss of any premium the Fund paid when it acquired the investment and could
result in the Fund's reinvesting the proceeds at a lower interest rate than the
retired CMO paid.  Because of the early retirement feature, CMOs may be more
volatile than many other fixed-income investments.

When-Issued Securities
- ----------------------

  Each Fund may purchase securities on a "when-issued" basis.  This means that
the Fund will 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 a 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 a Fund has outstanding obligations to buy when-issued
securities, it will maintain liquid high-grade assets in a segregated account at
its custodian bank in an amount sufficient to satisfy these obligations.

Rule 144A Securities
- --------------------
    
    The Worldwide 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
- ------------------

  Each Fund may invest in securities of issuers organized or headquartered
outside the United States ("foreign securities").  The Growth, Core Value and
Small Cap Value Funds will not purchase a foreign security if, as a result, the
Fund's holdings of foreign securities would exceed 20% of the Fund's total
assets.  The Small Company Growth, Mid-Cap Value, Mid-Cap Growth and Strategic
Value Funds may invest any portion of its assets in securities of Canadian
issuers, but will not purchase other foreign securities if, as a result, the
Funds' holding of non-U.S. and non-Canadian securities would exceed 20% of the
Funds' total assets.
 
  Although investing in foreign securities may increase a Fund's diversification
and reduce portfolio volatility, 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 government
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.  A
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.

  A Fund's investments in foreign securities may include investments in
countries whose economies or securities markets are not yet 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 a Fund investing in these
securities may be affected favorably or unfavorably by changes in currency
exchange rates or exchange control regulations.  Changes in the value relative
to the U.S. dollar of a foreign currency in which a 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.


<PAGE>
 
  In addition, although part of a 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
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 a 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 a Fund's net income available for
distribution to shareholders.

Foreign Currency Hedging Transactions
- -------------------------------------

  Each Fund that invests in foreign securities 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 a 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, a Fund might purchase or sell a foreign
currency on a spot (that is, cash) basis at the prevailing spot rate.  If
conditions warrant, the Funds may also enter into private contracts to purchase
or sell foreign currencies at a future date ("forward contracts").  The Funds
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 Funds
may not be able to dispose of over-the-counter options readily.

  Foreign currency transactions involve costs and may result in losses.  In
addition, each Fund's ability to engage in currency hedging transactions may be
limited by tax considerations.

Options and Futures Transactions
- --------------------------------
    
The International Equity, Worldwide, Small Company Growth, Mid-Cap Value, Mid-
Cap Growth and Strategic Value Funds may buy, sell or write options on
securities, securities indexes, currencies or futures contracts. The Small
Company Growth, Mid-Cap Value, Mid-Cap Growth and Strategic Value Funds may buy
and sell futures contracts on securities, securities indexes or currencies. The
Funds 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 Funds own or intend 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 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 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 a 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 Funds exceeds
(or is less than) the price of the offsetting purchase, the Funds will realize a
gain (or loss).

The value of options purchased by the Funds and futures contracts held by the
Funds may fluctuate up or down 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 a Funds' portfolio. All transactions in options
and futures involve the possible risk of loss to the Funds of

<PAGE>
 
all or a significant part of the value of its investment. In some cases, the
risk of loss may exceed the amount of the Funds' investment. The Funds will be
required, however, to set aside with its custodian bank certain assets in
amounts sufficient at all times to satisfy its obligations under options,
futures and contracts.

The successful use of options and futures will usually depend on the ability to
forecast stock market, currency or other financial market movements correctly.
The Funds' 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 a Funds to close its positions on a timely basis.
There can be no assurance that such a market will exist at any particular item.
In the case of options that are not traded on an exchange ("over-the-counter"
options), a Fund is at risk that the other party to the transaction will default
on its obligations, or will not permit a Fund to terminate the transaction
before its scheduled maturity. As a result of these characteristics, the Funds
will treat most over-the-counter options (and the assets it segregates to cover
its obligations thereunder) as illiquid.

  The options and futures markets of foreign countries are small compared to
those of the United States and consequently are characterized in most cases by
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.
    
Securities Lending
- ------------------

  The Small Company Growth, Mid-Cap Value, Mid-Cap Growth and Strategic Value
Funds may lend their 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.

                            PERFORMANCE INFORMATION

Portfolio Managers' Past Performance
- ------------------------------------

  The performance information presented in the graphs below relates to the
institutional private accounts managed by the portfolio managers of the Small
Company Growth Fund and the Strategic Value Fund that have investment objectives
and policies substantially similar to those of the relevant Fund.  The Funds are
newly organized and have no performance record of their own.  The information
below should not be considered a prediction of the future performance of any
Fund. The performance of the Funds may be higher or lower than the performance
of a fund or account that has substantially similar investment objectives and
policies.  The  performance information shown below for the accounts described
below is adjusted to give effect to the higher of the level of the actual
expenses of the accounts during the periods shown or the annualized expenses
projected for the relevant Fund's Retail Class shares during the first fiscal
year.

Small Company Growth Accounts
- -----------------------------

  Christopher R. Ely, Portfolio Manager of the Small Company Growth Fund, and
Philip C. Fine and David L. Smith, Assistant Portfolio Managers of the Small
Company Growth Fund, also serve, and have served, in those capacities for other
accounts that have investment objectives and investment policies substantially
similar to the Small Company Growth Fund (the "Small Company Growth Accounts").
Prior to July 22, 1996,  Messrs. Ely, Fine and Smith were affiliated with
another advisory firm.  The following graph shows total returns for the one and
two year periods ended September 30, 1996 for the Small Company Growth Accounts.
The information presented in footnote (2) below the graph represents the total
return of the Keystone Institutional Small Cap Growth Fund and Keystone Small
Company Growth Fund II, which have investment objectives and policies
substantially similar to those of the Small Company Growth Fund and which, from
their inception through July 11, 1996, were managed by Messrs. Ely, Fine and
Smith in their capacities as employees of the firm with which they were then
affiliated.  The performance information shown below is adjusted to give effect
to the higher of the level of the actual expenses of the Accounts during the
periods shown or the annualized expenses projected for the Fund's Retail Class
shares during the first full fiscal year.     
 

                                                                              15

A bar graph appears here, illustrating the one and two year annual returns for
the periods ended September 30, 1996 for the Accounts (1)(2), the Russell 2000
Index, the Russell 2000 Growth Index and the S&P 600 Index.  The data points
from the chart are as follows:
 
Accounts                    %

Russell 2000 Index          %

Russell 2000 Growth Index   %

S&P 600 Index               %

(1)  The annual total return for the Accounts for the period June 29, 1994
(inception of the Accounts) to September 30, 1996 was [_]%.  The Accounts were
managed by Messrs. Ely, Fine and Smith throughout the periods shown except for
the period July 11, 1996 through September 16, 1996 when the management of the
Accounts was in transition from the former adviser to Loomis Sayles.

(2)  In the case of the Keystone Institutional Small Cap Growth Fund
("Institutional Fund"), the total return for the period January 1, 1996
(inception of the Institutional Fund) to July 11, 1996 (the date that Messrs.
Ely, Fine and Smith ceased management of the Institutional Fund) was [_]%.   In
the case of the Keystone Small Company Growth Fund II ("Fund II"), the total
return for February 20, 1996,  the date of the Fund's inception, through July
11, 1996 was [_].  The information relating to Fund II does not take into
account the sales charges of Fund II.  The lower total return of Fund II
compared to the Institutional Fund and the Accounts is partially attributable to
certain tax restrictions.

Strategic Value Accounts
- ------------------------

  Philip J. Schettewi, portfolio manager of the Strategic Value Fund, also
serves as portfolio manager for other accounts that have substantially the same
investment objective and investment policies as the Strategic Value Fund  (the
"Strategic Value Accounts").  The following graph shows the total returns for
the period from __________ through ____________ for the Strategic Value
Accounts.  The graph also shows the total return of the Standard & Poor's/Barra
Value Index for [each] [the same] periods.

                                 FUND EXPENSES

  Each Fund pays Loomis Sayles a monthly investment advisory fee.  This fee is
at the following annual percentage rate of the Fund's average daily net assets:

<TABLE>    
<CAPTION>
 
          Fund                     Fee Rate

          Strategic Value              .50
 
</TABLE>     

                      16
<PAGE>
 
  In addition to the investment advisory fee, each 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,
expenses of preparing, printing and mailing prospectuses to existing
shareholders and fees of trustees who are not directors, officers or employees
of Loomis Sayles and its affiliated companies.

    
  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 operating expenses of the Institutional Class shares to .75% of the
average net assets of the Growth, Core Value and Strategic Value Funds and to
1.00% of average annual net assets for the International Equity, Small Cap Value
Fund, Small Company Growth, Mid-Cap Value, Mid-Cap Growth and Strategic Value
Funds. Loomis Sayles may change or terminate these voluntary arrangements at any
time, but the Funds' prospectus would be supplemented to describe the change and
such prospectus supplement would be mailed to shareholders 30 days before
termination of the arrangements.     

  Loomis Sayles may pay certain broker-dealers and financial intermediaries
whose customers are existing shareholders of the Funds a continuing fee in an
amount of 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 customers' accounts with the Funds.

                            PORTFOLIO TRANSACTIONS
     
  Portfolio turnover considerations will not limit Loomis Sayles' investment
discretion in managing the Funds' assets. The Funds anticipate that their
portfolio turnover rates will vary significantly from time to time depending on
the volatility of economic and market conditions.  High portfolio turnover may
involve higher costs and higher levels of taxable gains. Although it is not
possible to predict the portfolio turnover rate with certainty, Loomis Sayles
does not expect the Small Cap Value, Small Company Growth, Mid-Cap Value, Mid-
Cap Growth and Strategic Value Funds' portfolio turnover rates to exceed
_______%, _____%, _____%, _____%, and ____ %, respectively.     

  Loomis Sayles selects brokers and dealers to execute portfolio transactions
for the Funds.  Subject to seeking best price and execution, Loomis Sayles may
allocate these transactions to brokers or dealers whose customers have invested
in the Trust.

                            HOW TO PURCHASE SHARES

  An investor may make an initial purchase of shares of any Fund by submitting a
completed application form and payment to:

                         Boston Financial Data Services
                         P.O. Box 8314
                         Boston, Massachusetts  02266-8314
                         Attn: Loomis Sayles Funds

    
  The minimum investment for the Institutional Class of each Fund's shares is $1
million in that Fund.  An investment minimum of $2500 applies to shareholders of
any Fund who have accounts that have been in continuous existence since December
31, 1996 ( "Existing Shareholders"), the trustees of the Trust and investment
advisory clients of Loomis Sayles (and their directors, officers and employees)
and the parents, spouses and children of the foregoing and employees of Loomis
Sayles and their parents, spouses and children.  The investment minimum may be
waived by Loomis Sayles in its sole discretion and will be waived for new
shareholders in the Loomis Sayles Funds who initially invests less than $1
million but sign letters of intent stating their intention to bring their
balance to $1 million within six months of the initial purchase. The Distributor
reserves the right to redeem the accounts at net asset value of shareholders
that have signed a letter of intent but fail to meet the investment minimum
within the specified time. Subsequent investments must be at least $50.00.
     

                                                                              17
<PAGE>
 
  Shares of any Fund may be purchased by (i) cash, (ii) exchanging securities on
deposit with a custodian acceptable to Loomis Sayles or (iii) a combination of
such securities and cash.  Purchase of shares of the Fund in exchange for
securities is subject in each case to the determination by Loomis Sayles that
the securities to be exchanged are acceptable for purchase by the Fund.  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 which 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 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 1-800-633-3330.

  Loomis Sayles will not approve the acceptance of securities in exchange for
shares of any 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 Fund shares by
exchange of securities.

  All purchases made by check should be in U.S. dollars and made payable to the
Loomis Sayles Funds or 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, Boston Financial Data Services, Inc.
("BFDS"), the shareholder servicing agent for State Street Bank and Trust
Company ("State Street Bank"), opens an account, applies the payment to the
purchase of full and fractional Fund shares and mails a statement of the account
confirming 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 (Fund Name and
Institutional Class), DDA #9904-622-9, Shareholder Name, Shareholder Account
Number."  A bank may charge a fee for transmitting funds by wire.

  Each Fund reserves the right to reject any purchase order, including orders in
connection with exchanges, for any reason which the Fund in its sole discretion
deems appropriate.  Although the Funds do not presently anticipate that they
will do so, each 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 each Fund are sold with no sales charge.
The net asset value of each 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
outstanding.  Portfolio securities are valued at their market value as more
fully described in the Statement of Additional Information.

  Each Fund may accept telephone orders from broker-dealers who have been
previously approved by the Fund.  It is the responsibility of such broker-
dealers to promptly forward purchase or redemption orders to the Fund.  Although
there is no sales charge levied directly by the Fund, 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 or Loomis Sayles.

                                                                              18
<PAGE>
 
    
  Each Fund also offers a Retail Class of shares that has a $250,000 investment
minimum and bears higher expenses. Because of its lower expenses, the
Institutional Class of shares is expected to have a higher total return than the
Retail Class of shares.     


                             SHAREHOLDER SERVICES

  The Funds offer 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 the 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.  Shares of the Institutional Class of any Fund may
     -----------------------                                                    
     be exchanged for shares of the Institutional Class of any other Fund or for
     shares of certain money market funds advised by New England Funds
     Management, L.P., an affiliate of Loomis Sayles.  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 for taking advantage of short-
     term swings in the market, and the Funds reserve the right to terminate or
     limit the privilege of any shareholder who makes more than 4 exchanges in
     any calendar year.  The Funds may terminate or change the terms of the
     exchange privilege at any time, upon 60 days' notice to shareholders.
     
     Retirement Plans.  The Institutional Class of the Funds' 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 (this appears on
an investor's confirmation statement) and should indicate any special capacity
in which they are 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) 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, an investor must have his or her signature guaranteed by an
eligible guarantor.  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.

  If an investor has requested certificates for the investment, an investor must
enclose the certificates and a properly completed redemption form or stock
power.  The Funds recommend that certificates be sent by registered mail.

                                                                              19

  When an investor telephones a redemption request, the proceeds are wired to
the bank account previously chosen by the investor.  A wire fee (currently
$5.00) 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, an investor must send in this change on the Service Options Form with a
signature guarantee.  Telephonic 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. 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 and Trust Company ("State Street").  BFDS will employ these or other
reasonable procedures to confirm that instructions communicated by telephone are
genuine; the Fund, State Street, BFDS 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 information, 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
fifteen 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 which 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.


                DIVIDENDS, CAPITAL GAIN DISTRIBUTIONS AND TAXES

  The Funds declare and pay their net investment income to shareholders as
dividends annually.  Each 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 Funds declare or pay dividends.

  Dividends and capital gain distributions will automatically be reinvested in
additional shares of the same Fund on the record date unless an investor has
elected to receive cash.

  Each Fund intends to qualify as a regulated investment company under the
Internal Revenue Code of 1986, as amended.  As such, so long as a 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.

  Income dividends and short term capital gain distributions are taxable as
ordinary income whether distributed in cash or additional shares.  Long-term
capital gain distributions from all Funds are taxable as long-term capital gains
whether distributed in cash or additional shares and regardless of how long an
investor has owned shares of a Fund.

  Each 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.


<PAGE>
 
  Certain designated dividends from the Funds are expected to be eligible for
the dividends-received deduction for corporate shareholders.

  State Street Bank will send each investor and the IRS 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
       Funds. Before investing, an investor should consult his or her own tax
       adviser for more information concerning the federal, state and local tax
       consequences of investing in, redeeming or exchanging Fund shares.

                              SUMMARY OF EXPENSES
    
     The following information is provided to assist in understanding the
 various expenses that an investor in a Fund will bear indirectly.  Except in
 the case of the High Yield, Investment Grade Bond and Intermediate Maturity
 Bond Funds, the information is based on expenses of the Institutional Class of
 shares for the Funds' fiscal year ended December 31, 1995.  The High Yield,
 Investment Grade Bond and Intermediate Maturity Bond Funds did not commence
 operations until 1996; the information about each shown below is based on
 annualized projected expenses of the Institutional Class of shares for the
 period from the Fund's commencement of operations through December 31, 1996.
 The information below should not be considered a representation of past or
 future expenses, as actual expenses may be greater or less than those shown.
 Also, the assumed 5% annual return in the Example should not be considered a
 representation of investment performance as actual performance will depend upon
 actual investment results of securities held in the particular Fund's
 portfolio.

    /1/  A $5 charge applies to any wire transfer of redemption proceeds from 
         any Fund. A 2.00% redemption fee applies with respect to shares of the
         High Yield Fund redeemed within one (1) year of purchase. Loomis Sayles
         may, in its discretion, waive redemption fees on shares of the High
         Yield Fund as set forth under the heading "How to Redeem Shares" if it
         determines that there are minimal brokerage and transaction costs
         incurred in connection with the redemption.     
        
    /2/  The management fees shown in the table have been restated to reflect 
         a reduction in management fees payable to Loomis Sayles. Actual
         Management fees for the fiscal year ended December 31, 1995 were _____%
         for the Global Bond Fund, _____% for the U.S. Government Securities
         Fund, _____% for the Municipal Bond Fund, and _____% for the Short-Term
         Bond Fund.     
        
    /3/  Loomis Sayles has voluntarily agreed, for an indefinite period, to 
         limit these Funds' total operating expenses to the percentages of net
         assets shown above. Without this agreement, estimated total operating
         expenses would have been 1.94% for the High Yield Fund, _______% for
         the Intermediate Maturity Bond Fund, and _______% for the Investment
         Grade Bond Fund and actual Total Operating Expenses for the fiscal year
         ended December 31, 1995, 1.69% for the Global Bond Fund, 1.22% for the
         U.S. Government Securities Fund, 2.02% for the Municipal Bond Fund, and
         1.03% for the Short-Term Bond Fund.     
        
    /4/  Under SEC rules, new funds are required to show expenses for the 
         one- and three-year periods only.     

                                                                               4

                                   THE TRUST

     Each 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.  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.

 Loomis Sayles Bond Fund
 -----------------------

     The Fund's investment objective is high total investment return through a
 combination of current income and capital appreciation.

     The Fund seeks to achieve its objective by normally investing substantially
 all of its assets in debt securities (including convertibles), although up to
 20% of its assets may be invested in preferred stocks. At least 65% of the
 Fund's total assets will normally be invested in bonds. The Fund may invest any
 portion of its assets in securities of Canadian issuers, and 20% of its assets
 in securities of other foreign issuers. The Fund will also invest less than 35%
 of its assets in securities of below investment grade quality (commonly known
 as "junk bonds").
     
     The Fund may invest in collateralized mortgage obligations ("CMOs")  and
 Rule 144A securities. The Fund may engage in foreign currency hedging and swap
 transactions.     

     The percentages of the Fund's assets invested during the fiscal year ended
 December 31, 1995 in securities assigned to the various rating categories by
 Standard & Poor's Rating Group ("Standard & Poor's") and Moody's Investors
 Services, Inc. ("Moody's") were as follows:  "AAA"/"Aaa" 13.2%; "AA"/"Aa" 9.2%;
 "A"/"A" 10.9%; "BBB"/"Baa" 32.3%; "BB"/"Ba" 12.0%; "B"/"B" 12.7%; "CCC"/"Caa"
 9.7%.

 Loomis Sayles High Yield Fund
 -----------------------------

     The Fund's investment objective is high total investment return through a
 combination of current income and capital appreciation.
     
     The Fund seeks to attain its objective by normally investing substantially
 all of its assets in debt securities, although up to 20% of its assets may be
 invested in preferred stocks and up to 10% of its assets may be invested in
 common stocks.  The Fund may also invest in convertible bonds, when-issued
 securities, CMOs, options and Rule 144A securities.  The Fund may invest any
 portion of its assets in securities of Canadian issuers and up to 50% of its
 assets in the securities of other foreign issuers.  The Fund may engage in
 foreign currency hedging and swap transactions.     

     The Fund will normally invest at least 65% of its assets in fixed income
 securities of below investment grade quality (commonly referred to as "junk
 bonds"), which are securities rated below BBB by Standard & Poor's or below Baa
 by Moody's, including securities in the lowest rating categories, and unrated
 securities that Loomis Sayles determines to be of comparable quality. See "More
 Information about the Funds' Investments -- Lower Rated Fixed Income
 Securities."

 Loomis Sayles Global Bond Fund
 ------------------------------

     The Fund's investment objective is high total investment return through a
 combination of high current income and capital appreciation.

     The Fund seeks to achieve its objective by investing primarily in
 investment grade fixed income obligations (including convertibles and CMOs)
 denominated in various currencies, including U.S. dollars, or in multicurrency
 units.

     Under normal conditions, the Fund will invest at least 65% of its total
 assets in bonds of issuers from at least three countries which may include the
 United States, and no more than 40% of its assets in issuers headquartered in
 any one country. However, up to 100% of the Fund's assets may be denominated in
 U.S. dollars.  For temporary defensive purposes, the Fund may invest as much as
 100% of its assets in debt securities, rated AAA by Standard & Poor's or Aaa by
 Moody's at the time of purchase, of issuers from one or two countries, which
 may include the United States.

                                                                              10

 Loomis Sayles U.S. Government Securities Fund
 ---------------------------------------------

     The Fund's investment objective is high total investment return through a
 combination of current income and capital appreciation.

     The Fund seeks to achieve its objective by investing substantially all its
 assets in securities issued or guaranteed by the U.S. Government or its
 authorities, agencies or instrumentalities ("U.S. Government Securities"),
 including CMOs, and in certificates representing undivided interests in the
 interest or principal of U.S. Treasury securities.  At least 65% of the Fund's
 total assets will normally be invested in U.S. Government Securities.

 Loomis Sayles Municipal Bond Fund
 ---------------------------------

     The Fund's investment objective is as high a level of current income exempt
 from federal income tax as is consistent with the preservation of capital.

     The Fund seeks to achieve its objective by normally investing substantially
 all of its assets in securities the income from which is, in the opinion of
 issuer's counsel at the time of issuance, exempt from federal income tax ("tax
 exempt securities"). It is a fundamental policy of the Fund that, during
 periods of normal market conditions, at least 80% of its net assets will be
 invested in tax exempt securities.  Normally at least 80% of its assets will be
 invested in issues rated A or better, and at least 65% of its assets will be
 invested in bonds.  All issues will be rated at least BBB or Baa (or, if
 unrated, be of equivalent credit quality as determined by Loomis Sayles) at the
 time of purchase.  Bonds of BBB or Baa quality have some speculative
 characteristics. Changes in economic conditions or other circumstances are more
 likely to lead to a weakened capacity to make principal and interest payments
 than is the case with higher grade bonds.

 Loomis Sayles Short-Term Bond Fund
 ----------------------------------

     The Fund's investment objective is high total investment return through a
 combination of current income and capital appreciation with relatively low
 fluctuation in net asset value.
     
     The Fund seeks to achieve its objective by normally investing substantially
 all of its assets in debt securities (including convertibles and CMOs),
 although up to 20% of its assets may be invested in non-convertible preferred
 stock.  At least 65% of the Fund's total assets will normally be invested in
 bonds with a remaining maturity of 5 years or less.  The Fund may invest a
 limited portion of its assets in securities of foreign issuers.  The Fund may
 engage in foreign currency hedging and swap transactions.     

     In an effort to minimize fluctuations in market value, the Fund is expected
 to maintain an average dollar-weighted maturity of between one and three years.
     
 Loomis Sayles Investment Grade Bond Fund
 ----------------------------------------     
     
     The Fund's investment objective is high total investment return through a
 combination of capital appreciation and current income.     
     
     The Fund seeks to achieve its objective by normally investing its assets
 primarily in fixed income securities of investment grade quality although up to
 20% of its assets may be invested in preferred stocks.  Investment grade
 securities include those rated BBB and above by Standard & Poor's and those
 rated Baa and above by Moody's and unrated securities that Loomis Sayles
 determines to be of comparable quality.  The Fund may also invest up to 10% of
 its assets in fixed income securities of below invest grade quality, including
 securities in the lowest rating categories and unrated securities that Loomis
 Sayles determines to be of comparable quality.  The debt securities in which
 the Fund may invest include corporate securities, U.S. Government securities,
 commercial paper, zero coupon securities, mortgage-backed securities, asset-
 backed securities, convertible bonds and when-issued securities.  The Fund may
 engage in options and futures transactions, repurchase transactions, foreign
 currency hedging transactions and securities lending.  The Fund may invest any
 portion of its assets in the securities of Canadian issuers and up to 20% of
 its assets in the securities of other foreign issuers.  The Fund may engage in
 foreign currency hedging and swap transactions.     

                                                                              11

 Loomis Sayles Intermediate Maturity Bond Fund
 ---------------------------------------------     
     
     The Fund's investment objective is high total investment return through a
 combination of current income and capital appreciation.     
     
     The Fund seeks to obtain its objective by normally investing at least 90%
 of its assets in fixed income securities of investment grade quality with an
 average dollar weighted maturity of between three and ten years.  For purposes
 of the 90% test, a security will be treated as being of investment grade
 quality if it is rated by at least one major rating agency in one of its top
 four rating categories at the time of purchase or, if unrated, is determined by
 Loomis Sayles to be of comparable quality.  The Fund may also invest up to 10%
 of its assets in fixed income securities of below investment grade quality
 which are securities rated below BBB by Standard & Poor's and below Baa by
 Moody's and unrated securities that Loomis Sayles believes are of comparable
 quality, including securities in the lowest rating categories and unrated
 securities determined by Loomis Sayles to be of comparable quality.  The fixed
 income securities in which the Fund may invest include corporate securities,
 U.S. Government securities, commercial paper, zero coupon securities,
 mortgage-backed securities, asset-backed securities, convertible bonds and
 when-issued securities.  The Fund may engage in options and future
 transactions, repurchase transactions, foreign currency hedging transactions
 and securities lending.  The Fund may invest any portion of its assets in the
 securities of Canadian issuers and up to 20% of its assets in securities of
 other foreign issuers.  The Fund may engage in foreign currency hedging and
 swap transactions.     
     
 All Funds
 ---------     
     
     For temporary defensive purposes, each Fund may invest any portion of its

 Debt and Other Fixed Income Securities
 --------------------------------------
     
     The Bond, High Yield, Global Bond, U.S. Government Securities, Investment
 Grade Bond Fund and Municipal Bond Funds may all invest in fixed income
 securities of any maturity.  Although the Short-Term Bond Fund expects to
 maintain an average weighted maturity of less than three years, individual
 portfolio holdings may have maturities longer than three years. The
 Intermediate Maturity Bond Fund expects to maintain an average dollar weighted
 maturity between three and ten years. Fixed income securities pay a specified
 rate of interest or dividends, or a rate that is adjusted periodically by
 reference to some specified index or market rate.  Fixed income securities
 include securities issued by federal, state, local and foreign governments and
 related agencies, and by a wide range of private issuers.  Because interest
 rates vary, it is impossible to predict the income of a Fund that invests in
 fixed income securities for any particular period.  The net asset value of such
 a Fund's shares will vary as a result of changes in the value of the securities
 in the Fund's portfolio.     

     Fixed income securities are subject to market and credit risk.  Market risk
 relates to changes in a security's value as a result of changes in interest
 rates generally.  In general, the values of fixed income securities increase
 when prevailing interest rates fall and decrease when interest rates rise.
 Credit risk relates to the ability of the issuer to make payments of principal
 and interest.

 U.S. Government Securities
 --------------------------

     U.S. Government Securities have different kinds of government support.  For
 example, some U.S. Government Securities, such as U.S. Treasury bonds, are
 supported by the full faith and credit of the United States, whereas certain
 other U.S. Government Securities issued or guaranteed by federal agencies or
 government-sponsored enterprises are not supported by the full faith and credit
 of the United States.

     Although U.S. Government Securities generally do not involve the credit
 risks associated with other types of fixed income securities, the market values
 of U.S. Government Securities do go up and down as interest rates change.
 Thus, for example, the value of an investment in a Fund that holds U.S.
 Government Securities may fall during times of rising interest rates.  Yields
 on U.S. Government Securities tend to be lower than those on corporate
 securities of comparable maturities.

                                                                              12
<PAGE>
 
     Some U.S. Government Securities, such as Government National Mortgage
 Association Certificates ("GNMA"), are known as "mortgage-backed" securities.
 Interest and principal payments on the mortgages underlying mortgage-backed
 U.S. Government Securities are passed through to the holders of the security.
 If a Fund purchases mortgage-backed securities at a discount or a premium, the
 Fund will recognize a gain or loss when the payments of principal, through
 prepayment or otherwise, are passed through to the Fund and, if the payment
 occurs in a period of falling interest rates, the Fund may not be able to
 reinvest the payment at as favorable an interest rate.  As a result of these
 principal prepayment features, mortgage-backed securities are generally more
 volatile investments than many other fixed income securities.

     In addition to investing directly in U.S. Government Securities, the Funds
 may purchase certificates of accrual or similar instruments ("strips")
 evidencing undivided ownership interests in interest payments or principal
 payments, or both, in U.S. Government Securities.  These investment instruments
 may be highly volatile.  For purposes of its policy of normally investing at
 least 65% of its total assets in U.S. Government Securities, the U.S.
 Government Securities Fund will not treat a strip as a U.S. Government Security
 unless the strip itself is directly issued or guaranteed by the U.S. Government
 or an agency, authority or instrumentality thereof.

 Tax Exempt Securities
 ---------------------

     Issuers of tax exempt securities may make interest and principal payments
 from money raised through a variety of sources, including (1) the issuer's
 general taxing power, (2) a specific type of tax such as a property tax, or (3)
 a particular facility or project such as a highway.  The ability of an issuer
 of tax exempt bonds to make these payments could be affected by litigation,
 legislation or other political events, or the bankruptcy of the issuer.  The
 interest on tax exempt securities issued after August 15, 1986 is retroactively
 taxable from the date of issuance if the issuer does not comply with certain
 requirements concerning the use of bond proceeds and the application of
 earnings on bond proceeds.

 Lower Rated Fixed Income Securities
 -----------------------------------
     
     The Bond, High Yield, Global Bond, Short-Term Bond, Investment Grade Bond
 and Intermediate Maturity Bond Funds may each invest a portion of its assets in
 securities rated below investment grade (that is, below BBB or Baa and commonly
 referred to as "junk bonds"), including securities in the lowest rating
 categories, and comparable unrated securities. The Bond Fund may invest less
 than 35%, the Global Bond and Short-Term Bond Funds each may invest up to 20%,
 the Investment Grade Bond and Intermediate Maturity Bond Funds each may invest
 up to 10% and the High Yield Fund will normally invest at least 65% of its
 assets in such securities.  For purposes of the foregoing percentages, a
 security will be treated as being of investment grade quality if at the time a
 Fund acquires it at least one major rating agency has rated the security in its
 top four rating categories (even if another such agency has issued a lower
 rating), or if the security is unrated but Loomis Sayles determines it to be of
 investment grade quality.  Lower rated fixed income securities generally
 provide higher yields, but are subject to greater credit and market risk, than
 higher quality fixed income securities.  Lower rated fixed income securities
 are considered predominantly speculative with respect to the ability of the
 issuer to meet principal and interest payments.  Achievement of the investment
 objective of a Fund investing in lower rated fixed income securities may be
 more dependent on the investment adviser's own credit analysis than is the case
 with higher quality bonds.  The market for lower rated fixed income securities
 may be more severely affected than some other financial markets by economic
 recession or substantial interest rate increases, by changing public
 perceptions of this market or by legislation that limits the ability of certain
 categories of financial institutions to invest in these securities.  In
 addition, the secondary market may be less liquid for lower rated fixed income
 securities.  This lack of liquidity at certain times may affect the values of
 these securities and may make the valuation and sale of these securities more
 difficult.  Securities in the lowest rating categories may be in poor standing
 or in default.  Securities in the lowest investment grade category (BBB or Baa)
 have some speculative characteristics.     

 For more information about the ratings services' descriptions of the various
 ----------------------------------------------------------------------------
 rating categories, see Appendix A.
 ----------------------------------

 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.
 Therefore, the value of an investment in a Fund that invests in equity
 securities may sometimes 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.

 Zero Coupon Securities
 ----------------------

                                                                              13
<PAGE>
 
     The Funds may each invest in "zero coupon" fixed income securities.  These
 securities accrue interest at a specified rate, but do not pay interest in cash
 on a current basis.  A Fund investing in zero coupon securities is required to
 distribute the income on these securities to Fund shareholders as the income
 accrues, even though the Fund is not receiving the income in cash on a current
 basis.  Thus the Fund may have to sell other investments to obtain cash to make
 income distributions.  The market value of zero coupon securities is often more
 volatile than that of non-zero coupon fixed income securities of comparable
 quality and maturity.

 Mortgage-Backed Securities
 --------------------------

     All of the Funds except the Municipal Bond Fund may invest in mortgage-
 backed securities, such as GNMA or Federal National Mortgage Association
 certificates, which differ from traditional debt securities .  Among the major
 differences are that interest and principal payments are made more frequently,
 usually monthly, and that principal may be prepaid at any time because the
 underlying mortgage loans generally may be prepaid at any time.  As a result,
 if a Fund purchases these assets at a premium, a faster-than-expected
 prepayment rate will reduce yield to maturity, and a slower-than-expected
 prepayment rate will have the opposite effect of increasing yield to maturity.
 If a Fund purchases mortgage-backed securities at a discount, faster- than-
 expected prepayments will increase, and slower-than-expected prepayments will
 reduce, yield to maturity.  Prepayments, and resulting amounts available for
 reinvestment by the Fund, are likely to be greater during period of declining
 interest rates and, as a result, are likely to be reinvested at lower interest
 rates.  Accelerated prepayments on securities purchased at a premium may result
 in a loss of principal if the premium has not been fully amortized at the time
 of prepayment.  Although these securities will decrease in value as a result of
 increases in interest rates generally, they are likely to appreciate less than
 other fixed-income securities when interest rates decline because of the risk
 of prepayments.
 
 Collateralized Mortgage Obligations
 -----------------------------------
     
     The Bond, High Yield, Global Bond, U.S. Government Securities, Short-Term
 Bond, Intermediate Grade Bond, and Intermediate Maturity Bond Funds each may
 invest in CMOs.  A CMO is a security backed by a portfolio of mortgages or
 mortgage-backed securities held under an indenture.  CMOs may be issued either
 by U.S. Government instrumentalities or by non-governmental entities.  The
 issuer's obligation to make interest and principal payments is secured by the
 underlying portfolio of mortgages or mortgage-backed securities.  CMOs are
 issued with a number of classes or series which have different maturities and
 which may represent interests in some or all of the interest or principal on
 the underlying collateral or a combination thereof. CMOs of different classes
 are generally retired in sequence as the underlying mortgage loans in the
 mortgage pool are repaid. In the event of sufficient early prepayments on such
 mortgages, the class or series of CMOs first to mature generally will be
 retired prior to its maturity.  As with other mortgage-backed securities, the
 early retirement of a particular class or series of CMOs held by a Fund could
 involve the loss of any premium the Fund paid when it acquired the investment
 and could result in the Fund's reinvesting the proceeds at a lower interest
 rate than the retired CMO paid.  Because of the early retirement feature, CMOs
 may be more volatile than many other fixed-income investments.     

 Asset-Backed Securities
 -----------------------
     
     The Bond, Global Bond, High Yield, Short-Term Bond, Investment Grade Bond
 and Intermediate Duration Bond Funds may invest in asset-backed securities.
 Through the use of trusts and special purpose corporations, automobile and
 credit card receivables are securitized in pass-through structures similar to
 mortgage past-through structures or in a pay-through structure similar to the
 CMO structure.  Generally, the issuers of asset-backed bonds, notes or pass-
 through certificates are special purpose entities and do not have any
 significant assets other than the receivables securing such obligations.  In
 general, the collateral supporting asset-backed securities is of shorter
 maturity than mortgage loans.  Instruments backed by pools of receivables are
 similar to mortgage-backed securities in that they are subject to unscheduled
 prepayments of principal prior to maturity.  When the obligations are prepaid,
 the Fund will ordinarily reinvest the prepaid amounts in securities the yields
 of which reflect interest rates prevailing at the time.  Therefore, a Fund's
 ability to maintain a portfolio that includes high-yielding asset-backed
 securities will be adversely affected to the extent that prepayments of
 principal must be reinvested in securities that have lower yields than the
 prepaid obligations.  Moreover, prepayments of securities purchased at a
 premium could result in a realized loss.     

 When-Issued Securities
 ----------------------

     Each Fund may purchase securities on a "when-issued" basis.  This means
 that the Fund will 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 a Fund commits to buy it and the payment date,
 the Fund may

                                                                              14
<PAGE>
 
 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 a Fund has outstanding obligations to buy when-issued
 securities, it will maintain liquid high-grade assets in a segregated account
 at its custodian bank in an amount sufficient to satisfy these obligations.

 Rule 144A Securities
 ---------------------

     The Bond and High Yield Funds 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
 ------------------
     
     Each Fund (except the U.S. Government Securities and Municipal Bond Funds)
 may invest in securities of issuers organized or headquartered outside the
 United States ("foreign securities").  The Short-Term Bond Fund will not
 purchase a foreign security if, as a result, the Fund's holdings of foreign
 securities would exceed 20% of the Fund's total assets.  The Bond, Investment
 Grade Bond, and Intermediate Maturity Bond Funds may invest any portion of its
 assets in securities of Canadian issuers, but will not purchase other foreign
 securities 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.  The High Yield Fund
 may invest any portion of its assets in securities of Canadian issuers and up
 to 50% of its assets in the securities of other foreign issuers.     

     Although investing in foreign securities may increase a Fund's
 diversification and reduce portfolio volatility, 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
 government 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.  A 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.

     A Fund's investments in foreign securities may include investments in
 countries whose economies or securities markets are not yet 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 a Fund investing in these
 securities may be affected favorably or unfavorably by changes in currency
 exchange rates or exchange control regulations.  Changes in the value relative
 to the U.S. dollar of a foreign currency in which a 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 a 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
 converted into U.S. dollars will be greater than the equivalent

                                                                              15
<PAGE>
 
 amount in such currency of such expenses at the time they were incurred.

      In determining whether to invest assets of the Bond, High Yield, Global
 Bond, Investment Grade Bond, Intermediate Maturity Funds 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 a Fund's net income available for
 distribution to shareholders.

 Foreign Currency Hedging Transactions
 -------------------------------------

       The Funds may engage in foreign currency exchange transactions 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 a 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, a Fund might purchase or sell a foreign currency
 on a spot (that is, cash) basis at the prevailing spot rate.  If conditions
 warrant, the Funds may also enter into private contracts to purchase or sell
 foreign currencies at a future date ("forward contracts").  The Funds 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 Funds may not be able to dispose of over-the-counter options readily.

     Foreign currency transactions involve costs and may result in losses.  In
 addition, each Fund's ability to engage in currency hedging transactions may be
 limited by tax considerations.

 Swaps
 -----
     
    The Funds may enter into interest rate or currency swaps.  The Funds will
 enter into these transactions primarily to preserve a return or spread on a
 particular investment or portion of its portfolio, to protect against currency
 fluctuations, as a duration management technique or to protect against any
 increase in the price of securities a Fund anticipates purchasing at a later
 date. Interest rate swaps involve the exchange by a Fund with another party of
 their respective commitments to pay or receive interest (for example, an
 exchange of floating rate payments for fixed rate payments with respect to a
 notional amount of principal.)  A currency swap is an agreement to exchange
 cash flows on a notional amount based on changes in the relative values of the
 specified currencies.  The Fund will maintain liquid assets in a segregated
 custodial account to cover its current obligations under swap agreements.
 Because swap agreements are not exchange-traded, but are private contracts into
 which the Fund and a swap counterparty enter as principals, the Fund may
 experience a loss or delay in recovering assets in the counterparty were to
 default on its obligations.     

 Options and Futures Transactions
 --------------------------------
     
     The Funds (except the U.S. Government Securities and Municipal Bond Funds)
 may buy, sell or write options on securities, securities indexes, currencies or
 futures contracts and may buy and sell futures contracts on securities,
 securities indexes or currencies. The Funds 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 Funds own or intend 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 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
 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 a 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
 Funds exceeds (or is less than) the price of the offsetting purchase, the Funds
 will realize a gain (or loss).

                                                                              16
<PAGE>
 
     The value of options purchased by the Funds and futures contracts held by
 the Funds may fluctuate up or down 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 a Funds' portfolio. All transactions in
 options and futures involve the possible risk of loss to the Funds 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 Funds' investment. The Funds will be
 required, however, to set aside with its custodian bank certain assets in
 amounts sufficient at all times to satisfy its obligations under options,
 futures and contracts.

     The successful use of options and futures will usually depend on the
 ability to forecast stock market, currency or other financial market movements
 correctly. The Funds' 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 a Funds to close its
 positions on a timely basis. There can be no assurance that such a market will
 exist at any particular item. In the case of options that are not traded on an
 exchange ("over-the-counter" options), a Fund is at risk that the other party
 to the transaction will default on its obligations, or will not permit a Fund
 to terminate the transaction before its scheduled maturity. As a result of
 these characteristics, the Funds will treat most over-the-counter options (and
 the assets it segregates to cover its obligations thereunder) as illiquid.

     The options and futures markets of foreign countries are small compared to
 those of the United States and consequently are characterized in most cases by
 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
 ---------------------
     
     Each Fund may invest in repurchase agreements.  In repurchase agreements, a
 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 a Fund to earn a
 return on available cash at minimal market risk, although the Series may be
 subject to various delays and risks of loss if the seller is unable to meet its
 obligations to repurchase.     

 Securities Lending
 ------------------

     The Investment Grade Bond and Intermediate Maturity Bond Funds may lend
 their 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.

                                     FUND EXPENSES

     Each Fund pays Loomis Sayles a monthly investment advisory fee.  This fee
 is at the following annual percentage rate of the Fund's average daily net
 assets:

<TABLE>    
<CAPTION>
              Fund                                      Fee Rate

              Investment Grade Bond                        .40
              Intermediate Maturity Bond                   .40
</TABLE>     

     In addition to the investment advisory fee, each 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, expenses of preparing, printing and mailing prospectuses to
 existing shareholders and fees of trustees who

                                                                              19

 are not directors, officers or employees of Loomis Sayles or its affiliated
 companies.
     
     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 Fund total annual operating expenses to .75% of the average net assets of
 the High Yield Fund, to 1.00% of the average net assets of the Bond Fund, to
 .60% of the average net assets of the U.S. Government Securities and Municipal
 Bond Funds, to .50% of the average net assets of the Short Term Bond Fund, to
 .90%of the average net assets of the Global Bond Fund, and to .55% of the
 average net assets of the Investment Grade Bond and the Intermediate Grade Bond
 Funds.     


                            PORTFOLIO TRANSACTIONS
     
     Portfolio turnover considerations will not limit Loomis Sayles' investment
 discretion in managing the Funds' assets.  The Funds anticipate that their
 portfolio turnover rates will vary significantly from time to time depending on
 the volatility of economic and market conditions.  High portfolio turnover may
 involve higher costs and higher levels of taxable gains.  Although it is not
 possible to predict the portfolio turnover rate with certainty, Loomis Sayles
 does not expect the portfolio turnover rate of the High Yield, Investment Grade
 Bond and Intermediate Grade Bond Funds to exceed 60%, _____%, and _____%,
 respectively.     

     Loomis Sayles selects brokers and dealers to execute portfolio transactions
 for the Funds.  Subject to seeking best price and execution, Loomis Sayles may
 allocate these transactions to brokers or dealers whose customers have invested
 in the Trust.


                            HOW TO PURCHASE SHARES

     An investor may make an initial purchase of shares of any Fund by
 submitting a completed application form and payment to:

                           Boston Financial Data Services
                           P.O. Box 8314
                           Boston, Massachusetts  02266-8314
                           Attn: Loomis Sayles Funds
     
     The minimum investment for the Institutional Class of each Fund's shares is
 $1 million in that Fund.  A $2500 minimum investment applies to shareholders of
 any Fund who have accounts that have been in continuous existence since
 December 31, 1996 ( "Existing Shareholders"), the trustees of the Trust and
 investment advisory clients of Loomis Sayles (and their directors, officers and
 employees) and the parents, spouses and children of the foregoing and employees
 of Loomis Sayles and their parents, spouses and children.  The investment
 minimum may be waived by Loomis Sayles in its sole discretion and will be
 waived for any new shareholder in the Loomis Sayles Funds who initially invests
 less than $1 million but signs a letter of intent stating the shareholders
 intention to bring his or her balance to $1 million within six months of the
 initial purchase.  Loomis Sayles reserves the right to redeem the accounts at
 net asset value of shareholders that have signed a letter of intent but fail to
 meet the minimum within the specified time. Subsequent investments must be at
 least $50.00.     
     
     Shares of any Fund may be purchased by (i) cash, (ii) exchanging securities
 on deposit with a custodian acceptable to Loomis Sayles or (iii) a combination
 of such securities and cash. Loomis Sayles will not approve the acceptance of
 securities in exchange for shares of any 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 Fund shares 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
 which 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 by the investor from the issuer.  A gain or loss for federal
 income tax purposes would be

                                                                              20
<PAGE>
     
 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 1-800-633-3330.     

     All purchases made by check should be in U.S. dollars and made payable to
 the Loomis Sayles Funds or, in the case of a retirement account, the custodian
 or trustee.  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, Boston Financial Data Services,
 Inc. ("BFDS"), the shareholder servicing agent for State Street Bank and Trust
 Company ("State Street Bank"), opens an account, applies the payment to the
 purchase of full and fractional Fund shares and mails a statement of the
 account confirming 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 (Fund Name and
 Institutional Class), DDA #9904-622-9, Shareholder Name, Shareholder Account
 Number."  A bank may charge a fee for transmitting funds by wire.

     Each Fund reserves the right to reject any purchase order, including orders
 in connection with exchanges, for any reason which the Fund in its sole
 discretion deems appropriate.  Although the Funds do not presently anticipate
 that they will do so, each 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 each Fund are sold with no sales charge.
 The net asset value of each 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 outstanding.  Portfolio securities are valued at their market value
 as more fully described in the Statement of Additional Information.

     Each Fund may accept telephone orders from broker-dealers who have been
 previously approved by the Fund.  It is the responsibility of such broker-
 dealers to promptly forward purchase or redemption orders to the Fund.
 Although there is no sales charge levied directly by the Fund, 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 or Loomis Sayles.

     Each Fund also offers a Retail Class of shares that has a $250,000
 investment minimum and bears higher expenses. Because of its lower expenses,
 the Institutional Class of shares is expected to have a higher total return
 than the Retail Class of shares.


                             SHAREHOLDER SERVICES

     The Funds offer 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 the 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.  Shares of the Institutional Class of any Fund
      -----------------------                                                
      may be exchanged for shares of the Institutional Class of any other Fund
      or for shares of certain money market funds advised by New England Funds
      Management, L.P., an affiliate of Loomis Sayles.  Exchanges may be made by
      written instructions or by telephone,     

                                                                              21
<PAGE>
 
          
      unless an investor elected on the application to decline telephone
      exchange privileges.  The exchange privilege should not be viewed as a
      means for taking advantage of short-term swings in the market, and the
      Funds reserve the right to terminate or limit the privilege of any
      shareholder who makes more than 4 exchanges in any calendar year. The
      Funds may terminate or change the terms of the exchange privilege at any
      time, upon 60 days' notice to shareholders. Exchanges of shares of the
      High Yield Fund purchased within one year of such exchanges will be
      subject to a redemption fee of 2.00% of the amount exchanged. For purposes
      of determining whether a redemption fee is payable with respect to shares
      of the High Yield Fund purchased by exchange of shares of another Fund,
      the one year period shall be deemed to begin on the date of such purchase
      by exchange.     

      Retirement Plans.  The Institutional Class of the Funds' 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.
 Proceeds from a written request may be sent to the investor in the form of a
 check.  As described below, an investor may also redeem shares by calling BFDS
 at 800-626-9390.  Proceeds resulting from a 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 (this appears on
 an investor's confirmation statement) and should indicate any special capacity
 in which they are signing (such as trustee or custodian or on behalf of a
 partnership, corporation or other entity). Shareholders 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) 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, an investor must have his or her signature guaranteed by an
 eligible guarantor.  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.

     If an investor has requested certificates for the investment, an investor
 must enclose the certificates and a properly completed redemption form or stock
 power.  The Funds recommend that certificates be sent by registered mail.

     When an investor telephones a redemption request, the proceeds are wired to
 the bank account previously chosen by the investor.  A wire fee (currently
 $5.00) 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, an investor must send in this change on the Service Options Form with
 a signature guarantee.  Telephonic 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.  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 and Trust Company ("State Street").

                                                                              22
<PAGE>
 
 BFDS will employ these or other reasonable procedures to confirm that
 instructions communicated by telephone are genuine; the Fund, State Street,
 BFDS 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 information, 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, 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
 Fund purchased within one (1) year of such redemption. Loomis Sayles, in its
 discretion, may waive the 2.00% redemption fee with respect to shares of the
 High Yield Fund.     

     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 fifteen 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 which 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.

     Loomis Sayles may pay certain broker-dealers and financial intermediaries
 whose customers own shares of the Funds a continuing fee in an amount of 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 customers' accounts with the Funds.


                DIVIDENDS, CAPITAL GAIN DISTRIBUTIONS AND TAXES
     
     The Global Bond Fund declares and pays its net investment income to
 shareholders as dividends [monthly]; the Bond, High Yield, U.S. Government
 Securities, Investment Grade Bond, Intermediate Maturity Bond Funds declare and
 pay dividends quarterly; the Municipal Bond and Short-Term Bond Funds declare
 dividends daily and make payments monthly.  Each 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
 Funds declare or pay dividends.     

     Dividends and capital gain distributions will automatically be reinvested
 in additional shares of the same Fund on the record date unless an investor has
 elected to receive cash.

     Each Fund intends to qualify as a regulated investment company under the
 Internal Revenue Code of 1986, as amended. As such, so long as a 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.

     Except in the case of income dividends from tax exempt bond interest paid
 by the Municipal Bond Fund (see below), an investor's income dividends and
 short term capital gain distributions are taxable as ordinary income whether
 distributed in cash or additional shares.  Long-term capital gain distributions
 from all Funds are taxable as long-term capital gains whether distributed in
 cash or additional shares and regardless of how long an investor has owned
 shares of the Fund.

     Each Fund (except the Municipal Bond Fund in the case of designated exempt-
 interest dividends, as described below) 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 (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 he or she is not subject to such
 withholding.

     Dividends derived from interest on U.S. Government securities may be exempt
 from state and local taxes.

                                                                              23
<PAGE>
 
     State Street Bank will send investors and the IRS an annual statement
 detailing federal tax information, including information about dividends and
 distributions paid during the preceding year.  An investor should keep this
 statement as a permanent record.  A fee may be charged for any duplicate
 information requested.

 Municipal Bond Fund
 -------------------

     Certain designated dividends paid by the Municipal Bond Fund that are
 derived from interest on tax exempt bonds ("exempt-interest dividends") may be
 excluded from gross income on federal tax returns.  However, if an investor
 receives social security or railroad retirement benefits, the investor may be
 taxed on a portion of those benefits as a result of receiving tax exempt
 income.  Also, tax exempt income may be taken into account for the federal
 alternative minimum tax.

     Other dividends and short term capital gains, if any, are taxable to the
 investor as ordinary income whether received in cash or additional shares.
 Distributions of long-term capital gains are taxable as long-term capital gains
 whether distributed in cash or additional shares, regardless of how long an
 investor has held the shares.

     If at least 95% of the Fund's dividends are designated as exempt-interest
 dividends, federal back-up withholding rules do not apply with respect to such
 dividends.

     The federal exemption for exempt-interest dividends does not result in
 exemption from state and local taxes.  Distributions of exempt-interest
 dividends may be exempt from local and state taxation to the extent they are
 derived from the state or locality in which the investor resides.  The Fund
 will report annually on a state-by-state basis the source of income the Fund
 received on tax exempt bonds that was paid out as dividends during the
 preceding year.

 NOTE:    The foregoing summarizes certain tax consequences of investing in the
          Funds. Before investing, an investor should consult his or her own tax
          adviser for more information concerning the federal, state and local
          tax consequences of investing in, redeeming or exchanging Fund shares.

                                                                              24

                    DESCRIPTION OF BOND RATINGS ASSIGNED BY
                             STANDARD & POOR'S AND
                        MOODY'S INVESTORS SERVICE, INC.

 STANDARD & POOR'S
 -----------------

                                      AAA

 This is the highest rating assigned by Standard & Poor's to a debt obligation
 and indicates an extremely strong capacity to pay interest and repay principal.

                                       AA

 Bonds rated AA also qualify as high quality debt obligations.  Capacity to pay
 interest and repay principal is very strong, and in the majority of instances
 they differ from AAA issues only in small degree.

                                       A

 Bonds rated A have a strong capacity to pay interest and repay principal,
 although they are somewhat more susceptible to the adverse effects of changes
 in circumstances and economic conditions.

                                      BBB

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

                                 BB, B, CCC, CC

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

                                       C

 The rating C is reserved for income bonds on which no interest is being paid.

                                       D

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

 Plus (+) or Minus (-):  The ratings from "AA" to "B" may be modified by the
 addition of a plus or minus sign to show relative standing within the major
 rating categories.

 -------------------------------

                                      Aaa

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

                                       Aa

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

                                       A

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

                                      Baa

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

                                       Ba

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

                                       B

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

                                      Caa

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

                                       Ca

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

                                       C

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

                                      A-2
<PAGE>
 
 Should no rating be assigned by Moody's, the reason may be one of the
 following:

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

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

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

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

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

 Note:  Those bonds in the Aa, A, Baa, Ba and B groups which Moody's believes
 possess the strongest investment attributes are designated by the symbols Aa1,
 A1, Baa1, Ba1 and B1.

                INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS

- --------------------------------------------------------------------------------
    
  The investment objective and policies of each series ("Fund") of Loomis Sayles
Funds (the "Trust"), are summarized in the Funds' Prospectuses under "Investment
Objectives and Policies" and "More Information About the Funds' Investments."
The investment policies of each Fund set forth in the Funds' Prospectuses and in
this Statement of Additional Information may be changed by the Funds' adviser,
subject to review and approval by the Trust's board of trustees, without
shareholder approval except that the investment objective of each Fund as set
forth in the Funds' Prospectuses and any Fund policy explicitly identified as
"fundamental" may not be changed without the approval of the holders of a
majority of the outstanding shares of the relevant Fund (which in each
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).     
    
  In addition to its investment objective and policies set forth in each Fund's
Prospectuses, the following investment restrictions are policies of each Fund
(and those marked with an asterisk are fundamental policies of each Fund):     

  Each 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 any Fund 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.  (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 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.  (For purposes of this restriction, the Municipal Bond Fund treats each
state and each separate political subdivision, agency, authority or
instrumentality of such state, each multistate agency or authority, and each
guarantor, if any, of obligations of any such issuer, as a separate issuer,
provided that the assets and revenues of the issuer are separate from those of
the government(s) that created the subdivision, agency, authority or
instrumentality.)     
    
    (6) With respect to 75% of its 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 each 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.)
Tax-exempt securities issued by governments or political subdivisions of
governments and purchased by the Municipal Bond Fund are not subject to this
restriction, since such issuers are not members of any industry.     
    
    *(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.     
    
    (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).     
<PAGE>
 
    
    (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 (1)
each Fund may acquire warrants or rights to subscribe to securities of companies
issuing such warrants or rights, or of parents or subsidiaries of such
companies, (2) the International Equity, Worldwide, High Yield, Small Company
Growth, Mid-Cap Value, Mid-Cap Growth, Strategic Value, Intermediate Maturity
Bond, Investment Grade Bond Fund and Global Bond Funds each may purchase and
sell put and call options on securities and (3) each Fund may 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 Funds have no current intention of investing in repurchase
agreements, they intend, based on the views of the staff of the Securities and
Exchange Commission (the "SEC"), to restrict their 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 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" - The Federal National Mortgage Association ("FNMA") 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 FNMA that are guaranteed as to
timely payment of principal and interest by FNMA 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

                                      -4-
<PAGE>
 
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 Funds' Prospectuses, 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 Prospectuses, each 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 a Fund that invests in fixed income securities 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 a 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 cash or U.S. Government Securities in an amount
equal to or greater than, on a daily basis, the amount of the Fund's when-issued
or delayed-delivery commitments.  Each 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).     

Convertible Securities
- ----------------------

    Convertible securities include corporate bonds, notes or preferred stocks of
U.S. or foreign issuers that can be converted into (that is, exchanged for)
common stocks or other equity securities.  Convertible securities also include
other securities, such as warrants, that provide an opportunity for equity
participation.  Because convertible securities can be converted into equity
securities, their values will normally vary in some proportion with those of the
underlying equity securities.  Convertible securities usually provide a higher
yield than the underlying equity, however, so that the price decline of a
convertible security may sometimes be less substantial than that of the
underlying equity security.

Zero Coupon Bonds
- -----------------

    Zero coupon bonds are debt obligations that do not entitle the holder to any
periodic payments of interest either for the entire life of the obligation or
for an initial period after the issuance of the obligations.  Such bonds are
issued and traded at a discount from their face amounts.  The amount of the
discount varies depending on such factors as the time remaining until maturity
of the bonds, prevailing interest rates, the liquidity of the security and the
perceived credit quality of the issuer.  The market prices of zero coupon bonds
generally are more volatile than the market prices of securities that pay
interest periodically and are likely to respond to changes in interest rates to
a greater degree than do non-zero coupon bonds having similar maturities and
credit quality. In order to satisfy a requirement for qualification as a
"regulated investment company" under the Internal Revenue Code (the "Code"),
each Fund must distribute each year at least 90% of its net investment income,
including the original issue discount accrued on zero coupon bonds.  Because a
Fund investing in zero coupon bonds will not on a current basis receive cash
payments from the issuer in respect of accrued original issue discount, the Fund
may have to distribute cash obtained from other sources in order to satisfy the
90% distribution requirement under the Code.  Such cash might be obtained from
selling other portfolio holdings of the Fund.  In some circumstances, such sales
might be necessary in order to satisfy cash distribution requirements even
though investment considerations might otherwise make it undesirable for the
Fund to sell such securities at such time.

Repurchase Agreements
- ---------------------

    Each 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 Funds 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

                                      -5-
<PAGE>
 
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.

Rule 144A Securities
- --------------------
    
    Each of the Funds 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.     

Tax Exempt Bonds
- ----------------

    Tax exempt bonds include debt obligations issued to obtain funds for various
public purposes, including the construction of a wide range of public facilities
such as bridges, highways, hospitals, housing, mass transportation, schools,
streets, and water and sewer works.  Other public purposes for which tax exempt
bonds may be issued include the refunding of outstanding obligations, obtaining
funds for general operating expenses, and obtaining funds to lend to other
public institutions and facilities.  In addition, prior to the Tax Reform Act of
1986, certain debt obligations known as industrial development bonds could be
issued by or on behalf of public authorities to obtain funds to provide
privately operated housing facilities, sports facilities, convention or trade
show facilities, airport, mass transit, port or parking facilities, air or water
pollution control facilities and certain local facilities for water supply, gas,
electricity, or sewage or solid waste disposal.  Such obligations are included
within the term tax exempt bonds if the interest paid thereon is, in the opinion
of bond counsel, exempt from federal income tax.  Interest on certain industrial
development bonds used to fund the construction, equipment, repair or
improvement of privately operated industrial or commercial facilities may also
be exempt from federal income tax.  The Tax Reform Act of 1986 eliminated some
types of tax exempt industrial revenue bonds but retained others under the
general category of "private activity bonds."  The interest on so-called
"private activity bonds" is exempt from ordinary federal income taxation but is
treated as a tax preference item in computing a shareholder's alternative
minimum tax liability.  The Municipal Bond Fund currently does not intend to
invest in private activity bonds.

    The Municipal Bond Fund may not be a desirable investment for "substantial
users" of facilities financed by industrial development bonds or for "related
persons" of substantial users.  See "Income Dividends, Capital Gain
Distributions and Tax Status."

    The two principal classifications of tax exempt bonds are general obligation
bonds and limited obligation (or revenue) bonds.  General obligation bonds are
obligations involving the credit of an issuer possessing taxing power and are
payable from the issuer's general unrestricted revenues and not from any
particular fund or source.  The characteristics and method of enforcement of
general obligation bonds vary according to the law applicable to the particular
issuer, and payment may be dependent upon an appropriation by the issuer's
legislative body.  Limited obligation bonds are payable only from the revenues
derived from a particular facility or class of facilities, or in some cases from
the proceeds of a special excise or other specific revenue source such as the
user of the facility.  Tax exempt industrial development bonds and private
activity bonds are in most cases revenue bonds and generally are not payable
from the unrestricted revenues of the issuer.  The credit and quality of such
bonds are usually directly related to the credit standing of the corporate user
of the facilities.  Principal and interest on such bonds is the responsibility
of the corporate user (and any guarantor).

    Prices and yields on tax exempt bonds are dependent on a variety of factors,
including general money market conditions, the financial condition of the
issuer, general conditions of the tax exempt bond market, the size of a
particular offering, the maturity of the obligation and the rating of the issue.
A number of these factors, including the ratings of particular issues, are
subject to change from time to time.  Information about the financial condition
of an issuer of tax exempt bonds may not be as extensive as that made available
by corporations whose securities are publicly traded.

    As noted in the Prospectus, obligations of issuers of tax exempt bonds are
subject to the provisions of bankruptcy, insolvency and other laws, such as the
Federal Bankruptcy Reform Act of 1978, affecting the rights and remedies of
creditors. Congress or state legislatures may seek to extend the time for
payment of principal or interest, or both, or to impose other constraints upon
enforcement of such obligations.  There is also the possibility that, as a
result of litigation or other conditions, the power or ability of issuers to
meet their obligations for the payment of interest and principal on their tax
exempt bonds may be

                                      -6-

materially affected, or their obligations may be found to be invalid or
unenforceable.  Such litigation or conditions may from time to time have the
effect of introducing uncertainties in the market for tax exempt bonds or
certain segments thereof, or materially affecting the credit risk with respect
to particular bonds.  Adverse economic, business, legal or political
developments might affect all or a substantial portion of the Fund's tax exempt
bonds in the same manner.

    From time to time the Municipal Bond Fund may have less than 80% of its net
assets invested in tax exempt bonds (1) for defensive purposes when deemed
prudent in the judgment of Loomis Sayles to protect shareholders' capital or (2)
on a temporary basis for liquidity purposes or pending the investment of
proceeds from sales of Fund shares.  The ability of the Fund to invest in
securities other than tax exempt bonds is limited by a requirement of the Code
that at least 50% of the Fund's total assets be invested in tax exempt
securities at the end of each calendar quarter.  See "Income Dividends, Capital
Gain Distributions and Tax Status."

    The Municipal Bond Fund may purchase and sell portfolio investments to take
advantage of changes or anticipated changes in yield relationships, markets or
economic conditions.  The Fund may also sell tax exempt bonds due to changes in
the adviser's evaluation of the issuer or cash needs resulting from redemption
requests for Fund shares.  The secondary market for tax exempt bonds typically
has been less liquid than that for taxable debt securities, and this may affect
the Fund's ability to sell particular tax exempt bonds, especially in periods
when other investors are attempting to sell the same securities.

Foreign Currency Transactions
- -----------------------------
    
    The Growth, Core Value, Small Cap Value, International Equity, Worldwide,
Small Company Growth, Mid-Cap Value, Mid-Cap Growth, Strategic Value, Bond,
Global Bond, Investment Grade Bond and Intermediate Maturity Bond Funds 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 a Fund may temporarily hold funds in
bank deposits in foreign currencies during the course of investment programs,
the value of the assets of a Fund as measured in United States dollars may be
affected by changes in currency exchange rates and exchange control regulations,
and a Fund may incur costs in connection with conversion between various
currencies.     

    A Fund may enter into forward contracts under two circumstances.  First,
when a 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 Funds 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 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 Funds' ability to engage in transactions in currency forward contracts
and options may be limited by tax considerations.

    Each Fund, in conjunction with its transactions in forward contracts,
options and futures (including the International Equity, Worldwide and Global
Bond Funds' transactions in options on securities described below), will
maintain in a segregated account with its custodian cash or high grade 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.

                                      -7-

Options
- -------
    
    As described in the Prospectus, the International Equity, Worldwide, High
Yield, Small Company Growth, Mid-Cap Value, Mid-Cap Growth, Strategic Value,
Global Bond, Investment Grade Bond and Intermediate Maturity Bond Funds each
may, for hedging purposes, purchase and sell call and put options on securities
it owns or intends to purchase.     

    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. A 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 which
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.

    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.

                                      -8-
<PAGE>
 
    The staff of the SEC has taken the position that over-the-counter options
should be treated as illiquid securities for purposes of each Fund's investment
restriction prohibiting it from investing more than 15% of its net assets in
illiquid securities. The Funds intend to comply with this position.

    Income earned by a 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 a
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.

25% of a Fund, it may be deemed to "control" such Fund.  As a result, it may not
be possible for matters subject to a vote of a majority of the outstanding
voting securities of a Fund to be approved without the affirmative vote of such
shareholders, and it may be possible for such matters to be approved by such
shareholders without the affirmative vote of any other shareholders.

*The Worldwide, High Yield, Investment Grade Bond, Small Company Growth, 
Mid-Cap Value, Mid-Cap Growth, Strategic Value and Intermediate Maturity Bond 
Funds had not commenced operations on December 31, 1995.     

    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 Funds; 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 Funds; 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 

                                      -16-
<PAGE>
 
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 each advisory agreement, if the total ordinary business expenses of a
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.  At present, the most restrictive state
annual expense limitation is 2 1/2% of a Fund's average annual net assets up to
$30,000,000, 2% of the next $70,000,000 of such assets and 1/2% of such assets
in excess of $100,000,000.  Loomis Sayles will not be required to reduce its fee
or pay such expenses to an extent or under circumstances which would result in
any 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 Prospectuses, 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.     

    Each 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
relevant 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 an advisory agreement must be approved by vote of a majority of the
outstanding voting securities of the relevant 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. Each 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 relevant Fund, upon sixty
days' written notice, or by Loomis Sayles upon ninety days' written notice, and
each terminates automatically in the event of its assignment. In addition, each
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 relevant Fund and by a majority of
the Trustees who are not interested persons of the Trust or Loomis Sayles.

    Each 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 Capital Growth Fund, New England Strategic Income Fund, New
England Star Advisers Fund and New England Balanced Fund, which are series of
New England Funds Trust I, 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,
the Avanti Growth 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 numerous other
corporate and fiduciary clients.     

    Loomis Sayles's sole general partner is Loomis Sayles & Company, Inc., which
is a wholly-owned subsidiary of New England Investment Companies, L.P. ("NEIC").
NEIC's sole general partner is New England Investment Companies, Inc., which is
a wholly-owned subsidiary of NEIC Holdings, Inc., a wholly-owned subsidiary of
Metropolitan Life Insurance Company.

    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 Funds also invest. If a 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 which a Fund
purchases or sells.  In other cases, however, it is believed that these
practices may benefit the Funds. It is the opinion of the trustees that the
desirability of retaining Loomis Sayles as adviser for the Funds outweighs the
disadvantages, if any, which might result from these practices.

    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 Funds and, in such capacity, is the registered owner of securities held in
book entry form belonging to the Funds.  Upon instruction, State Street Bank
receives and 

                                      -17-
<PAGE>
 
delivers cash and securities of the Funds 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 Funds and calculates the total net asset value, total net income
and net asset value per share of each Fund on a daily basis.
    
    Independent Accountants.  The Fund's independent accountants are Coopers &
    -----------------------                                                   
Lybrand L.L.P., One Post Office Square, Boston, Massachusetts. Coopers & Lybrand
conducts an annual audit of the Trust's financial statements, assists in the
preparation of the Funds' federal and state income tax returns and consults with
the Funds as to matters of accounting and federal and state income taxation. The
information under the caption "Financial Highlights" included in each Prospectus
has been so included, and the financial statements incorporated by reference
herein from the Fund's 1995 Annual Report have been so incorporated, in reliance
on the reports of Coopers & Lybrand, independent accountants, given on the
authority of said firm as experts in auditing and accounting.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE
                                        
- --------------------------------------------------------------------------------

    Funds Other Than the International Equity and Worldwide Funds.  In placing
    -------------------------------------------------------------              
orders for the purchase and sale of portfolio securities for each Fund other
than the International Equity and Worldwide Funds, 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
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 Funds 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 which 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's 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 Funds.  Receipt of services or products other
than research from brokers is not a factor in the selection of brokers.
Consistent with the Rules of Fair Practice of the National Association of
Securities Dealers, Inc., and subject to seeking best price and execution,
Loomis Sayles may, however, consider purchases of shares of the Trust by
customers of broker-dealers as a factor in the selection of broker-dealers to
execute the Trust's securities transactions.

    International Equity and Worldwide Funds.  In placing orders for the
    ----------------------------------------                            
purchase and sale of securities for the International Equity and Worldwide
Funds, Loomis Sayles follows the same policies as for the other Funds, except
that Loomis Sayles may cause the International Equity and Worldwide Funds to pay
a broker-dealer that provides brokerage and research services to Loomis Sayles
an amount of commission for effecting a securities transaction for those Funds
in excess of the amount another broker-dealer would have charged for effecting
that transaction.  Loomis Sayles must determine in good faith that such greater
commission is reasonable in relation to the value of the brokerage and research
services provided by the executing broker-dealer viewed in terms of that
particular transaction or Loomis Sayles's overall responsibilities to the Trust
and its other clients.  Loomis Sayles's authority to cause the International
Equity and Worldwide Funds to pay such greater commissions is also subject to
such policies as the Trustees of the Trust may adopt from time to time.

                            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 Declaration of Trust currently permits the trustees to issue an
unlimited number of full and fractional shares of each series.  Each share of
each Fund represents an equal proportionate interest in such Fund with each
other share of that Fund and is entitled to a proportionate interest in the
dividends and distributions from that Fund.  The shares of each Fund do not have
any preemptive rights.  Upon termination of any Fund, whether pursuant to
liquidation of the Trust or otherwise, shareholders of that Fund are entitled to
share pro rata in the net assets of that 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 each 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,
that Fund.  The underlying assets are segregated and are charged with the
expenses with respect to that 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 a particular 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 Fund, certain expenses may be legally chargeable against the assets of
all Funds.
    
    The Declaration of Trust also permits the trustees, without shareholder
approval, to subdivide any series of shares or Fund into various classes of
shares with such dividend preferences and other rights as the trustees may
designate.  Shares of each Fund (other than the U.S. Government Securities and
Municipal Bond Funds) 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 Trust or merge two or more existing portfolios.  Shareholders'
investments in such an additional or merged 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 any Fund, however, may be terminated at any time by vote of at
least two-thirds of the outstanding shares of each Fund affected.  The
Declaration of Trust further provides that the trustees may also terminate the
Trust or any Fund upon written notice to the shareholders.  As a matter of
policy, however, the trustees will not terminate the Trust or any Fund without
submitting the matter to a vote of the shareholders of the Trust or the relevant
Fund.

Voting Rights
- -------------
    
    As summarized in each 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.

                                      -20-
<PAGE>
 
    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).

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 each 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 each Fund are summarized in the
Fund's Prospectuses under "How to Purchase Shares."     

- --------------------------------------------------------------------------------

                                NET ASSET VALUE

- --------------------------------------------------------------------------------

    The net asset value of the shares of each Fund is determined by dividing
that 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

                                      -21-
<PAGE>
 
    
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 a Fund's portfolio securities that the value of that 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:  Christmas Day, New Year's Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, and Thanksgiving 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 any Fund's
portfolio securities occur during such period, then 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 any 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 State Street Bank 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 each 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 $10,000 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.

                                      -22-
<PAGE>
 
    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 any Fund and have the proceeds
applied on the same day to purchase shares of any other Fund or of New England
Cash Management Trust or New England Tax Exempt Money Market Trust.  Exchange of
shares of the High Yield Fund purchased within one year of such exchanges will
be subject to a redemption fee of 2.00% of the amount exchanged.  For purposes
of determining whether a redemption fee is payable with respect to shares of the
High Yield Fund purchased by exchange of shares of another fund, the one-year
period shall be deemed to begin on the date of such purchase by exchange.  The
value of shares exchanged must be at least $1,000 and all exchanges are subject
to the minimum investment requirement of the fund into which the exchange is
being made.  This option is summarized in each Prospectus under "Shareholder
Services--Free Exchange Privilege."     

    Exchanges may be effected by (1) making a telephone request by calling 800-
633-3330, provided that a special authorization form is on file with BFDS, or
(2) sending a written exchange request to BFDS accompanied 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," each Prospectus refers to
IRAs established under a prototype plan made available by Loomis Sayles.  These
plans may be funded with shares of any Fund, although it is expected that shares
of the Municipal Bond Fund would ordinarily not be an appropriate investment for
these plans.     

    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 each
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 each
Prospectus, a signature guarantee will not be required if the proceeds of the
redemption do not exceed $10,000 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.

                                      -23-
<PAGE>
 
    
    In order to redeem shares by telephone, a shareholder must either select
this service when completing the Fund application or must do so subsequently on
the Service Options Form available from BFDS.  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 completed Service Options Form with a signature guarantee.
Whenever the Service Options Form is used, the shareholder's signature must be
guaranteed as described above.  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 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
Fund redeemed within one (1) year of purchase, if applicable.  To the extent
that shares are redeemed at a time when other shares of the Fund are being
purchased, Loomis Sayles will treat the redemption (up to the amount being
concurrently purchased) as involving minimal brokerage and transaction costs and
will charge any redemption fee only with respect to the excess, if any, of the
amount of the redemption over the amount of the concurrent purchase.  If there
is more than one redemption at the time of a concurrent purchase, each of the
redeeming shareholders will share, pro rata, in the reduction in redemption fee
caused by the concurrent purchase.  Proceeds resulting from a written redemption
request will normally be mailed to you within seven days after receipt of your
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 you have recently purchased your shares by check and your
check was received less than fifteen days prior to the redemption request, the
Fund may withhold redemption proceeds until your check has cleared.     

    Each Fund will normally redeem shares for cash; however, each 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 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 each Prospectus under "Dividends, Capital Gain Distributions
and Taxes" it is the policy of each 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 particular 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.

    Each Fund intends to qualify each year as a regulated investment company
under Subchapter M of the Code.  In order so to qualify, 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) derive less
than 30% of its gross income from gains from the sale or other disposition of
securities held for less than three months; (iii) distribute at least 90% of its
dividend, interest and certain other taxable income each year; and (iv) at the
end of each fiscal quarter maintain at least 50% of the value of its total
assets in cash, 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 with no more than 25% of its
assets 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
each 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.  Each Fund
intends to make distributions sufficient to avoid imposition of the excise tax.
Distributions declared by a 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.
    
    Shareholders of each 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 Fund's Prospectuses) whether
received in cash or additional shares of the Fund.  Distributions by each Fund
of net income and short-term capital gains, if any, will be taxable to
shareholders as ordinary income.  Distributions of long-term capital gains, if
any, will be taxable to shareholders as long-term capital gains, without regard
to how long a shareholder has held shares of the Fund.  A loss on the sale of
shares held for 12 months or less will be treated as a long-term capital loss to
the extent of any long-term capital gain dividend paid to the shareholder with
respect to such shares.     

    Dividends and distributions on Fund shares received shortly after their
purchase, although in effect a return of capital, are subject to federal income
taxes.

    The International Equity, Worldwide and Global Bond Funds each may be
eligible to make an election under Section 853 of the Code so that its
shareholders will be able to claim a credit or deduction on their income tax
returns for, and will be required to treat as part of the amounts distributed to
them, their pro rata portion of qualified taxes paid by the relevant Fund to
foreign countries.  The ability of shareholders of the Fund to claim a foreign
tax credit is subject to certain limitations imposed by Section

                                      -25-
<PAGE>
 
904 of the Code, which in general limit the amount of foreign tax that may be
used to reduce a shareholder's U.S. tax liability to that amount of U.S. tax
which would be imposed on the amount and type of income in respect of which the
foreign tax was paid.  A shareholder who for U.S. income tax purposes claims a
foreign tax credit in respect of Fund distributions may not claim a deduction
for foreign taxes paid by the Fund, regardless of whether the shareholder
itemizes deductions.  Also, under Section 63 of the Code, no deduction for
foreign taxes may be claimed by shareholders who do not itemize deductions on
their federal income tax returns.  It should also be noted that a tax-exempt
shareholder, like other shareholders, will be required to treat as part of the
amounts distributed to it a pro rata portion of the income taxes paid by the
Fund to foreign countries.  However, that income will generally be exempt from
United States taxation by virtue of such shareholder's tax-exempt status and
such a shareholder will not be entitled to either a tax credit or a deduction
with respect to such income.  The International Equity, Worldwide and Global
Bond Funds will notify shareholders each year of the amount of dividends and
distributions and the shareholder's pro rata share of qualified taxes paid by
each such Fund to foreign countries.

    Each 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.

    Each Fund may limit its investments in certain "passive foreign investment
companies" in order to avoid certain taxes that arise as a result of such
investments.

    Redemptions and exchanges of each Fund's shares are taxable events and,
accordingly, shareholders may realize gains and losses on these transactions.
If shares have been held for more than one year, gain or loss realized will be
long-term capital gain or loss, provided the shareholder holds the shares as a
capital asset.  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 state and local taxes.
Shareholders are urged to consult their tax advisers regarding specific
questions as to federal, state 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).

                     CALCULATION OF YIELD AND TOTAL RETURN
                                        
- --------------------------------------------------------------------------------

    Yield.  Yield with respect to a Fund will be computed by dividing such
    -----                                                                 
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 Funds' yields will vary from time to
time depending upon

                                      -26-
<PAGE>
 
market conditions, the composition of the Funds' portfolios and operating
expenses of the Trust allocated to each Fund.  These factors, and possible
differences in the methods used in calculating yield, should be considered when
comparing a 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 Funds' shares and to the relative risks associated with the
investment objectives and policies of the Funds.

    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 Funds are specifically advised that the net asset value per
share of each Fund may vary, just as yields for each Fund may vary.  An
investor's focus on yield to the exclusion of the consideration of the value of
shares of that Fund may result in the investor's misunderstanding the total
return he or she may derive from that Fund.

    Total Return.  Total Return with respect to a Fund is a measure of the
    ------------                                                          
change in value of an investment in such 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:  (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.

(i) the ranking of performance figures relative to such figures for groups of
mutual funds categorized by Lipper Analytical Services, Inc. or Micropal, 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.     

    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.

    Micropal, Inc. distributes mutual fund rankings weekly and monthly.  The
    --------------                                                          
rankings are based upon performance calculated by Micropal, generally reflecting
changes in net asset value that can be adjusted for the reinvestment of capital
gains and dividends. If deemed appropriate by the user, performance can also
reflect deductions for sales charges.  Micropal rankings cover a variety of
performance periods, including year-to-date, 1-year, 5-year and 10-year
performance.  Micropal classifies mutual funds by investment objective and asset
category.

    Morningstar, Inc. distributes mutual fund ratings twice a month.  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.

of the Trust.  The Adviser hereby accepts such employment and agrees, at its own

<PAGE>
 
     3.   All activities in connection with the management of the affairs of the

be subject to the supervision and control of the Board of Trustees, any duly
constituted committee thereof or any officer of the Trust acting pursuant to
like authority.

     4.   In addition to performing at its expense the obligations set forth in
section 2 hereof, the Adviser shall furnish to the Trust at the Adviser's own

     managerial functions described in section 5); and

          (c) compensation, if any, of Trustees of the Trust who are directors,

     5.   Except as the Adviser may otherwise agree from time to time, nothing
in section 4 hereof shall require the Adviser to bear, or to reimburse the Trust
for:

          (a) any of the costs of printing and distributing the items referred
     to in subsection (n) of this section 5;

          (b) any of the costs of preparing, printing and distributing sales

     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 0.75%, 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
quarterly, as the Board of Trustees of the Trust may from time to time determine
and specify in writing to the Adviser.   The Adviser hereby acknowledges that
the Trust's obligation to pay such compensation is binding only on the assets
and property belonging to the Series.

     8.   If the total of all ordinary business expenses of the Series or the
Trust as a whole (including investment advisory fees but excluding taxes and
portfolio brokerage commissions) for any fiscal year exceeds the lowest
applicable percentage of average net assets or income limitations prescribed by
any state in which shares of the Series are qualified for sale, the Adviser
shall pay any such excess.  Solely for purposes of applying such limitations

                                      -3-
<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.

                                      -4-
<PAGE>
 
     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.

                                      -5-

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

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

     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.

and expenses borne by the Adviser hereunder, the Trust shall pay the Adviser
compensation at the annual percentage rate of 0.75%, or such lesser rate as the
Adviser may agree to from time to time. Such compensation shall be payable

Trust as a whole (including investment advisory fees but excluding taxes and

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

     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

     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

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

     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'

     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.

payment of any penalty.

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.

     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 0.40%, 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
quarterly, as the Board of Trustees of the Trust may from time to time determine
and specify in writing to the Adviser.   The Adviser hereby acknowledges that
the Trust's obligation to pay such compensation is binding only on the assets
and property belonging to the Series.

     8.  If the total of all ordinary business expenses of the Series or the
Trust as a whole (including investment advisory fees but excluding taxes and
portfolio brokerage commissions) for any fiscal year exceeds the lowest
applicable percentage of average net assets or income limitations prescribed by
any state in which shares of the Series are qualified for sale, the Adviser

                                      -3-
<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.

                             W I T N E S S E T H:

    In consideration of the premises and covenants hereinafter contained, the

    (b) Prior to the time of delivery of any shares by the Trust to, or on the
        order of, the Distributor, the Distributor shall pay or cause to be paid

3.  Fee.  For its services as general distributor of the Series shares, the
    ---

    paid monthly to the Distributor as soon as practicable after the end of the
    calendar month in which it accrues, but in any event within five business
    days following the last day of the month.

4.  Public Offering Price.  The public offering price shall be the net asset
    ---------------------                                                   
    value of Series shares. The net asset value of Series shares shall be
    determined in accordance with the provisions of the agreement and
    declaration of trust and by-laws of the Trust and the current prospectus(es)
    of the Trust relating to the Series shares.

5.  Trust Issuance of Series Shares.  The delivery of Series shares shall be
    -------------------------------                                         
    made promptly by a credit to a shareholder's open account for the relevant
    Series. The Trust reserves the right (a) to issue Series shares at any time
    directly to the shareholders of the Series as a stock dividend or stock
    split, (b) to issue to such shareholders Series shares, or rights to
    subscribe to Series shares, as all or part of any dividend that may be
    distributed to shareholders of the Series or as all or part of any optional

    Series, and (c) to sell Series shares in accordance with any current
    applicable prospectus of the Trust relating to the Series shares.

6.  Repurchase.  The Distributor shall act as agent for the Trust in connection
    ----------                                                                 
    with the repurchase of Series shares by the Trust to the extent and upon the
    terms and conditions set forth in the current applicable prospectus(es) of
    the Trust relating to the Series shares, and the Trust agrees to reimburse

    incurred in connection with such repurchases of shares.

7.  Undertaking Regarding Sales.  The Distributor shall use reasonable efforts
    ---------------------------                                               
    to sell Series shares but does not agree hereby to sell any specific number
    of Series shares and shall be free to act as distributor of the shares of
    other investment companies. Series shares will be sold by the Distributor
    only against orders therefor. The Distributor shall not purchase Series
    shares from anyone except in accordance with Sections 2 and 6 and shall not
    take "long" or "short" positions in Series shares contrary to the agreement
    and declaration of trust or by-laws of the Trust.

8.  Compliance.  The Distributor shall conform to the Conduct Rules of the
    ----------                                                            
    National Association of Securities Dealers, Inc. ("NASD") and the sale of
    securities laws of any jurisdiction in which it sells, directly or
    indirectly, any Series shares. The Distributor agrees to make timely
    filings, with the Securities and Exchange Commission (the "SEC") in
    Washington, D.C., the NASD and such other regulatory authorities as may be
    required, of any sales literature relating to the Series and intended for
    distribution to prospective investors. The Distributor also agrees to
    furnish to the Trust sufficient copies of any agreements or plans it intends
    to use in connection with any sales of

                                      -2-
<PAGE>
 
     Series shares in adequate time for the Trust to file and clear them with
     the proper authorities before they are put in use (which the Trust agrees
     to use its best efforts to do as expeditiously as reasonably possible), and
     not to use them until so filed and cleared.

9.   Registration and Qualification of Series Shares.  The Trust agrees to
     -----------------------------------------------                      
     execute such papers and to do such acts and things as shall from time to
     time be reasonably requested by the Distributor for the purpose of
     qualifying and maintaining qualification of the Series shares for sale
     under the so-called Blue Sky Laws of any state or for maintaining the
     registration of the Trust and of the Series shares under the federal
     Investment Company Act of 1940 (the "1940 Act") and the federal Securities
     Act of 1933, to the end that there will be available for sale from time to
     time such number of Series shares as the Distributor may reasonably be
     expected to sell. The Trust shall advise the Distributor promptly of (a)
     any action of the SEC or any authorities of any state or territory, of
     which it may be advised, affecting registration or qualification of the
     Trust or the Series shares, or rights to offer Series shares for sale, and
     (b) the happening of any event which makes untrue any statement or which
     requires the making of any change in the Trust's registration statement or
     its prospectus relating to the Series shares in order to make the
     statements therein not misleading.

10.  Distributor Independent Contractor.  The Distributor shall be an
     ----------------------------------                              
     independent contractor and neither the Distributor nor any of its officers
     or employees as such is or shall be an employee of the Trust. The
     Distributor is responsible for its own conduct and the employment, control
     and conduct of its agents and employees and for injury to such agents or
     employees or to others through its agents or employees. The Distributor
     assumes full responsibility for its agents and employees under applicable
     statutes and agrees to pay all employer taxes thereunder.

11.  Expenses Paid by Distributor.  While the Distributor continues to act as
     ----------------------------                                            
     agent of the Trust to obtain subscriptions for and to sell Series shares,
     the Distributor shall pay the following:

     (a) all expenses of printing (exclusive of typesetting) and distributing
         any prospectus for use in offering Series shares for sale, and all
         other copies of any such prospectus used by the Distributor, and

     (b) all other expenses of advertising and of preparing, printing and
         distributing all other literature or material for use in connection
         with offering Series shares for sale.

12.  Interests in and of Distributor.  It is understood that any of the
     -------------------------------                                   
     shareholders, trustees, officers, employees and agents of the Trust may be
     a shareholder, director, officer, employee or agent of, or be otherwise
     interested in, the Distributor, any affiliated

                                      -3-
<PAGE>
 
     person of the Distributor, any organization in which the Distributor may
     have an interest or any organization which may have an interest in the
     Distributor; that the Distributor, 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
     transaction hereunder except as otherwise provided in the agreement and
     declaration of trust or by-laws of the Trust, in the limited partnership
     agreement of the Distributor or by specific provision of applicable law.

13.  Words "Loomis" and "Sayles".  The Distributor and its parent, Loomis,
     ---------------------------                                          
     Sayles & Company, L.P., retain proprietary rights in the words "Loomis" and
     "Sayles," which may be used by the Trust and the Series only with the
     consent of the Distributor. The Distributor consents to the use by the
     Series of the name "Loomis Sayles Investment Grade Bond Fund" or any other
     name embodying the words "Loomis" or "Sayles," in such forms as the
     Distributor shall in writing approve, but only on condition and so long as
     (i) this Agreement shall remain in full force and (ii) the Trust shall
     fully perform, fulfill and comply with all provisions of this Agreement
     expressed herein to be performed, fulfilled or complied with by it. No such
     name shall be used by the Trust or the Series at any time or in any place
     or for any purposes or under any conditions except as in this section
     provided. The foregoing authorization by the Distributor to the Trust and
     the Series to use said words or letters as part of a business or name is
     not exclusive of the right of the Distributor itself to use, or to
     authorize others to use, the same; the Trust acknowledges and agrees that
     as between the Distributor and the Trust and the Series, the Distributor
     has the exclusive right so to use, or authorize others to use, said words
     and letters, and the Trust agrees to take such action as may reasonably be
     requested by the Distributor to give full effect to the provisions of this
     section (including, without limitation, consenting to such use of said
     words or letters). Without limiting the generality of the foregoing, the
     Trust agrees that, upon any termination of this Agreement by either party
     or upon the violation of any of its provisions by the Trust, the Trust
     will, at the request of the Distributor made within six months after the
     Distributor has knowledge of such termination or violation, use its best
     efforts to change the name of the Trust and the Series so as to eliminate
     all reference, if any, to the words "Loomis" and "Sayles" and will not
     thereafter transact any business in a name containing the words "Loomis" or
     "Sayles" in any form or combination whatsoever, or designate itself as the
     same entity as or successor to any entity of such name, or otherwise use
     the words "Loomis" or "Sayles" or any other reference to the Distributor.
     Such covenants on the part of the Trust and each Series shall be binding
     upon it, its trustees, officers, shareholders, creditors and all other
     persons claiming under or through it.

14.  Effective Date and Termination.  This Agreement shall become effective as
     ------------------------------                                           
     of the date of its execution, and

         with respect to the shares of a Series so long as such continuation is
         specifically approved at least annually (i) by the Board of Trustees of
         the Trust or by the vote of a majority of the votes which may be cast
         by shareholders of the Series and (ii) by a vote of a majority of the
         Board of Trustees of the Trust who are not interested persons of the
         Distributor or the Trust, 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' notice to
         the Distributor either by vote of a majority of the Trust's Board of
         Trustees then in office or by the vote of a majority of the votes which
         may be cast by shareholders of the Series.

     (c) This Agreement shall automatically terminate in the event of its
         assignment.

     (d) This Agreement may be terminated by the Distributor on ninety days'
         written notice to the Trust.

Loomis Sayles Funds
One Financial Center
Boston, Massachusetts  02111

Gentlemen:

     We are furnishing this opinion in connection with the proposed offer and
sale by Loomis Sayles Funds, a Massachusetts business trust (the "Trust"), of
shares of beneficial interest of its Loomis Sayles Growth Fund series, Loomis
Sayles Core Value Fund series, Loomis Sayles Small Cap Value Fund series, Loomis
Sayles International Equity Fund series, Loomis Sayles Worldwide Fund series,
Loomis Sayles Small Company Growth Fund series, Loomis Sayles Mid-Cap Value Fund
series, Loomis Sayles Mid-Cap Growth Fund series, Loomis Sayles Strategic Value
Fund series, Loomis Sayles Bond Fund series, Loomis Sayles High Yield Fund
series, Loomis Sayles Global Bond Fund series, Loomis Sayles U.S. Government
Securities Fund series, Loomis Sayles Municipal Bond Fund series, Loomis Sayles
Short-Term Bond Fund series, Loomis Sayles Investment Grade Bond Fund series and
Loomis Sayles Intermediate Maturity Bond Fund series (the "Shares") pursuant to
Registration Statement No. 33-39133 on Form N-1A under the Securities Act of
1933 (the "Registration Statement").

     We are familiar with the action taken by the Trustees of the Trust to
authorize the issuance of the Shares.  We have examined the Trust's By-Laws and
its Agreement and Declaration of Trust on file in the office of the Secretary of
State of the Commonwealth of Massachusetts and such other documents as we deem
necessary for the purposes of this opinion.

     We assume that upon sale of the Shares the Trust will receive the net asset
value thereof.

     Based upon the foregoing, we are of the opinion that the Trust is
authorized to issue an unlimited number of Shares, and that, when the Shares are
issued and sold, they will be validly issued, fully paid and nonassessable by
the Trust.

     The Trust is an entity of the type commonly known as a "Massachusetts
business trust."  Under Massachusetts law, shareholders could, under certain
circumstances, be held personally liable for the obligations of the Trust.
However, the Agreement and Declaration of Trust disclaims shareholder liability
for acts or obligations of the Trust 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 Agreement and Declaration of Trust provides for
indemnification out of the property of the particular series of shares for all
loss and expense of any shareholder of that series held personally liable solely
by reason of his or her having been a shareholder of that series.  Thus, the
risk of shareholder liability is limited to circumstances in which that series
itself would be unable to meet its obligations.

     We consent to the filing of this opinion as an exhibit to the Registration
Statement.

                                        Very truly yours,

 

                                        Ropes & Gray

                        Retail Class Distribution Plan


     This Plan (the "Plan") constitutes the Distribution Plan relating to the

series, Loomis Sayles Investment Grade Bond Fund series and Loomis Sayles
Intermediate Maturity Bond Fund series, each a series ("Series") of Loomis
Sayles Funds, a Massachusetts business trust (the "Trust").

     Section 1.  The Trust, on behalf of each Series, will pay to Loomis Sayles
Distributors, L.P., a Delaware limited partnership which acts as the Principal
Distributor of the Series' shares, or such other entity as shall from time to
time act as the Principal Distributor of the Series' shares (the "Distributor"),
a fee (the "Distribution Fee") at an annual rate not to exceed 0.25% of each
Series' average daily net assets attributable to the Retail Class shares.
Subject to such limit and subject to the provisions of Section 6 hereof, the
Distribution Fee shall be as approved from time to time by (a) the Trustees of
the Trust and (b) the Independent Trustees of the Trust.  The Distribution Fee
shall be accrued daily and paid monthly or at such other intervals as the
Trustees shall determine.  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 Series, or for providing personal services to investors in Retail
Class shares of the Series and/or the maintenance of shareholder 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 Series.  All payments under this Section 1 are intended to qualify as
"asset-based sales charges" or "service fees" as defined in the Conduct Rules of
the National Association of Securities Dealers, Inc. ("NASD").

     Section 2.  This Plan shall continue in effect for a period of more than
one year after January 1, 1997 only so long as such continuance is specifically
approved at least annually by votes of the majority (or whatever other
percentage may, from time to time, be required by Section 12(b) of the
Investment Company Act of 1940 (the "Act") or the rules and regulations
thereunder) of both (a) the Trustees of the Trust, and (b) the Independent
Trustees of the Trust, cast in person at a meeting called for the purpose of
voting on this Plan or such agreement.

     Section 3.  Any person authorized to direct the disposition of monies paid
or payable by the Trust pursuant to this Plan or any related agreement shall
provide to the Trustees of the Trust, and the Trustees shall review, at least
quarterly, a written report of the amounts so expended and the purposes for
which such expenditures were made.
<PAGE>
 
     Section 4.  This Plan may be terminated at any time by vote of a majority
of the Independent Trustees, or by vote of a majority of the outstanding Retail
Class shares of the Series.

     Section 5.  All agreements with any person relating to implementation of
this Plan shall be in writing, and any agreement related to this Plan shall
provide:

     A.  That such agreement may be terminated at any time, without payment of
         any penalty, by vote of a majority of the Independent Trustees or by
         vote of a majority of the outstanding Retail Class shares of the
         Series, on not more than 60 days' written notice to any other party to
         the agreement; and

     B.  That such agreement shall terminate automatically in the event of its
         assignment.

     Section 6.  This Plan may not be amended to increase materially the amount
of expenses permitted pursuant to Section 1 hereof without approval by a vote of
at least a majority of the outstanding Retail Class shares of the Series, and
all material amendments of this Plan shall be approved in the manner provided
for continuation of this Plan in Section 2.

     Section 7.  As used in this Plan, (a) the term "Independent Trustees" shall
mean those Trustees of the Trust who are not interested persons of the Trust,
and have no direct or indirect financial interest in the operation of this Plan
or any agreements related to it, and (b) the terms "assignment" and "interested
person" shall have the respective meanings specified in the Act and the rules
and regulations thereunder, and the term "majority of the outstanding Retail
Class shares of the Series" shall mean the lesser of the 67% or the 50% voting
requirements specified in clauses (A) and (B), respectively, of the third
sentence of Section 2(a)(42) of the Act, all subject to such exemptions as may

                              LOOMIS SAYLES FUNDS

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

                           Effective January 1, 1997

          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 and Institutional Class 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.
Except as noted below, 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.  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.

RETAIL CLASS SHARES

Distribution and Service Fees
- -----------------------------

          Retail Class shares pay distribution and service fees pursuant to
plans (the "Plans") adopted pursuant to Rule 12b-1 under the Investment Company
Act of 1940 (the "1940 Act"). Retail Class shares also bear any costs associated
with obtaining shareholder approval of any amendments to a Plan.  Pursuant to
the Plans, Retail Class shares may pay up to 0.25% of the relevant Fund's
average net assets attributable to the Retail Class shares (which percentage may
be less for certain Funds, as described in the Funds' registration statements as
from time to time in effect).  Amounts payable under the Plans are subject to
such further limitations as the Trustees may from time to time determine and as
set forth in the registration statement of each Fund as from time to time in
effect.

Exchange and Conversion Features
- --------------------------------

          To the extent provided in the registration statement of the relevant
Fund as from time to time in effect, Retail Class shares of any Fund may be
exchanged, at the holder's option and
<PAGE>
 
subject to minimum investment requirements, for Retail Class shares of any other
Fund that offers Retail Class shares, provided that Retail Class shares of such
other Fund are available to residents of the relevant state.  Retail Class
shares may also be exchanged for shares of certain money market funds advised by
New England Funds Management, L.P., an affiliate of Loomis Sayles.  The Funds
reserve the right to terminate or limit the exchange privilege of any
shareholder who makes more than four exchanges in a calendar year.  The Funds
may terminate or change the exchange privilege at any time upon 60 days' notice
to shareholders.

      Retail Class shares do not convert to any other class of shares.

INSTITUTIONAL CLASS SHARES

Distribution Fees
- -----------------

      Institutional Class shares pay no distribution fees.

Exchange and Conversion Features
- --------------------------------

          To the extent provided in the registration statement of the relevant
Fund as from time to time in effect, Institutional Class shares of any Fund may
be exchanged, at the holder's option, for Institutional Class shares of any
other Fund that offers Institutional Class shares, provided that Institutional
Class shares of such other Fund are available to residents of the relevant
state. Institutional Class shares may also be exchanged for shares of certain
money market funds advised by New England Funds Management, L.P., an affiliate
of Loomis Sayles.  The Funds reserve the right to terminate or limit the
exchange privilege of any shareholder who makes more than four exchanges in a
calendar year.  The Funds may terminate or change the exchange privilege at any
time upon 60 days' notice to shareholders.

      Institutional Class shares do not convert to any other class of shares.
