Exhibit 4

                     AGREEMENT AND PLAN OF REORGANIZATION

   This Agreement and Plan of Reorganization (the "Agreement") is made as of
October 26, 2007, by and between Natixis Value Fund (the "Acquired Fund"), a
series of Natixis Funds Trust I, a Massachusetts business trust (the "Trust"),
and Loomis Sayles Value Fund (the "Acquiring Fund"), a series of Loomis Sayles
Funds II, a Massachusetts business trust (the "Loomis Trust").

                            PLAN OF REORGANIZATION

   (a) The Acquired Fund shall sell, assign, convey, transfer and deliver to
the Acquiring Fund on the Exchange Date (as defined in Section 6) all of its
properties and assets, subject to liabilities. In consideration therefor, the
Acquiring Fund shall, on the Exchange Date, assume all of the liabilities of
the Acquired Fund existing at the Valuation Time (as defined in Section 3(c))
and deliver to the Acquired Fund a number of full and fractional Class A, Class
B, Class C and Class Y shares of beneficial interest of the Acquiring Fund (the
"Merger Shares") having for each such class an aggregate net asset value equal
to the value of the assets of the Acquired Fund attributable to such class
transferred to the Acquiring Fund on such date less the value of the
liabilities of the Acquired Fund attributable to such class assumed by the
Acquiring Fund on that date. It is intended that the reorganization described
in this Agreement shall be a reorganization within the meaning of Section 368
of the Internal Revenue Code of 1986, as amended and in effect from time to
time (the "Code").

   (b) Upon consummation of the transactions described in paragraph (a) of this
Plan of Reorganization, the Acquired Fund shall distribute the Merger Shares in
complete liquidation to its shareholders of record as of the Exchange Date,
each shareholder being entitled to receive that proportion of Merger Shares of
each class (consisting in the case of each shareholder of Merger Shares of the
same designated class as the shares of the Acquired Fund which that shareholder
holds) which the number of shares of that class of the Acquired Fund held by
such shareholder bears to the total number of shares of that class of the
Acquired Fund outstanding on such date. Certificates representing the Merger
Shares will not be issued. All issued and outstanding shares of the Acquired
Fund will simultaneously be cancelled on the books of the Acquired Fund.

   (c) As soon as practicable following the liquidation of the Acquired Fund as
aforesaid, the Acquired Fund shall be dissolved pursuant to the provisions of
the Agreement and Declaration of Trust of the Trust, as amended, and applicable
law, and its legal existence terminated. Any reporting responsibility of the
Acquired Fund is and shall remain the responsibility of the Acquired Fund up to
and including the Exchange Date and, if applicable, such later date on which
the Acquired Fund is dissolved.

                                      1



                                   AGREEMENT

   The Loomis Trust, on behalf of the Acquiring Fund, and the Trust, on behalf
of the Acquired Fund, agree as follows:

1. Representations, Warranties and Agreements of the Acquiring Fund. The Loomis
   Trust, and not the individual Trustees and officers thereof, on behalf of
   the Acquiring Fund, represents and warrants to and agrees with the Acquired
   Fund that:

    a. The Acquiring Fund is a series of shares of the Loomis Trust, a
       Massachusetts business trust duly established and validly existing under
       the laws of the Commonwealth of Massachusetts, and has power to own all
       of its properties and assets and to carry out its obligations under this
       Agreement. The Loomis Trust is qualified as a foreign association in
       every jurisdiction where required, except to the extent that failure to
       so qualify would not have a material adverse effect on the Loomis Trust.
       Each of the Loomis Trust and the Acquiring Fund has all necessary
       federal, state and local authorizations to carry on its business as now
       being conducted and to carry out this Agreement.

    b. The Loomis Trust is registered under the Investment Company Act of 1940,
       as amended (the "1940 Act"), as an open-end management investment
       company, and such registration has not been revoked or rescinded and is
       in full force and effect.

    c. A statement of assets and liabilities, statement of operations,
       statement of changes in net assets and a portfolio of investments
       (indicating their market values) of the Acquiring Fund as of and for the
       period ended March 31, 2007 have been furnished to the Acquired Fund
       prior to the Exchange Date. Such statement of assets and liabilities and
       schedule fairly present the financial position of the Acquiring Fund as
       of such date and said statements of operations and changes in net assets
       fairly reflect the results of its operations and changes in net assets
       for the periods covered thereby in conformity with generally accepted
       accounting principles.

    d. Since March 31, 2007, there has not been any material adverse change in
       the Acquiring Fund's financial condition, assets, liabilities or
       business (other than changes occurring in the ordinary course of
       business), or any incurrence by the Acquiring Fund of indebtedness. For
       the purposes of this subparagraph (d), distributions of net investment
       income and net realized capital gains, changes in portfolio securities,
       changes in the market value of portfolio securities or net redemptions
       shall be deemed to be in the ordinary course of business.

    e. The Loomis Trust is not in violation in any material respect of any
       provisions of its First Amended and Restated Agreement and Declaration
       of Trust or By-Laws or of any agreement, indenture, instrument,
       contract, lease or other undertaking to which the Loomis Trust is a
       party or by which the Acquiring Fund is bound, and the execution,
       delivery and performance of this Agreement will not result in any such
       violation.

                                      2



    f. The prospectuses and statement of additional information of the
       Acquiring Fund, each dated June 1, 2007, and each as from time to time
       amended or supplemented (collectively, the "Acquiring Fund Prospectus"),
       previously furnished to the Acquired Fund, (i) conform in all material
       respects to the applicable requirements of the Securities Act of 1933,
       as amended (the "1933 Act"), and (ii) did not as of such date and do not
       contain, with respect to the Loomis Trust or the Acquiring Fund, any
       untrue statements of a material fact or omit to state a material fact
       required to be stated therein or necessary to make the statements
       therein not misleading.

    g. There are no material legal, administrative or other proceedings pending
       or, to the knowledge of the Loomis Trust or the Acquiring Fund,
       threatened against the Loomis Trust or the Acquiring Fund, which assert
       liability on the part of the Loomis Trust or the Acquiring Fund. Neither
       the Loomis Trust nor the Acquiring Fund knows of any facts which might
       form the basis for the institution of such proceedings and is not a
       party to or subject to the provisions of any order, decree or judgment
       of any court or governmental body which materially and adversely affects
       its business or its ability to consummate the transactions herein
       contemplated.

    h. The Acquiring Fund has no known liabilities of a material nature,
       contingent or otherwise, other than those that will be shown as
       belonging to it on its statement of assets and liabilities as of
       March 31, 2007, and those incurred in the ordinary course of business as
       an investment company since such date. Prior to the Exchange Date, the
       Acquiring Fund will quantify and reflect on its balance sheet all of its
       material known liabilities and will advise the Acquired Fund of all
       material liabilities, contingent or otherwise, incurred by it subsequent
       to March 31, 2007, whether or not incurred in the ordinary course of
       business.

    i. As of the Exchange Date, the Acquiring Fund will have filed all federal
       and other tax returns and reports (giving effect to extensions) which,
       to the knowledge of the officers of the Loomis Trust, are required to be
       filed by the Acquiring Fund and has paid or will pay all federal and
       other taxes shown to be due on said returns or on any assessments
       received by the Acquiring Fund. All tax liabilities of the Acquiring
       Fund have been adequately provided for on its books, and no tax
       deficiency or liability of the Acquiring Fund has been asserted, and no
       question with respect thereto has been raised or is under audit, by the
       Internal Revenue Service or by any state, local or other tax authority
       for taxes in excess of those already paid, except as previously
       disclosed to the Acquired Fund.

    j. No consent, approval, authorization or order of any court or
       governmental authority is required for the consummation by the Acquiring
       Fund of the transactions contemplated by this Agreement, except such as
       may be required under the 1933 Act, the Securities Exchange Act of 1934,
       as amended (the "1934 Act"), the 1940 Act and state securities or blue
       sky laws (which term as used herein shall include the laws of the
       District of Columbia and of Puerto Rico).

                                      3



    k. There are no material contracts outstanding to which the Acquiring Fund
       is a party, other than as are or will be disclosed in the Registration
       Statement or the Acquired Fund Proxy Statement (each as defined in
       Section l(r) herein) or the Acquiring Fund Prospectus.

    l. To the best of its knowledge, all of the issued and outstanding shares
       of beneficial interest of the Acquiring Fund have been offered for sale
       and sold in conformity with all applicable federal and state securities
       laws (including any applicable exemptions therefrom), except as
       previously disclosed to the Acquired Fund, or the Acquiring Fund or its
       investment adviser has taken any action necessary to remedy any prior
       failure to have offered for sale and sold such shares in conformity with
       such laws.

    m. The Acquiring Fund qualifies and will at all times through the Exchange
       Date qualify for taxation as a "regulated investment company" under
       Subchapter M of the Code.

    n. The issuance of the Merger Shares pursuant to this Agreement will be in
       compliance with all applicable federal and state securities laws.

    o. The Merger Shares to be issued to the Acquired Fund have been duly
       authorized and, when issued and delivered pursuant to this Agreement,
       will be legally and validly issued Class A, Class B, Class C and Class Y
       shares of beneficial interest in the Acquiring Fund and will be fully
       paid and, except as set forth in the Registration Statement,
       nonassessable by the Acquiring Fund, and no shareholder of the Acquiring
       Fund will have any preemptive right of subscription or purchase in
       respect thereof.

    p. All issued and outstanding shares of the Acquiring Fund are, and at the
       Exchange Date will be, duly and validly issued and outstanding, fully
       paid and, except as set forth in the Registration Statement,
       nonassessable by the Acquiring Fund. The Acquiring Fund does not have
       outstanding any options, warrants or other rights to subscribe for or
       purchase any of the Acquiring Fund shares, nor is there outstanding any
       security convertible into any of the Acquiring Fund shares, except that
       Class B shares of the Acquiring Fund are convertible into Class A shares
       of the Acquiring Fund in the manner and on the terms described in the
       Acquiring Fund Prospectus and the Registration Statement.

    q. The Acquiring Fund's investment operations from inception to the date
       hereof have been in compliance in all material respects with the
       investment policies and investment restrictions set forth in the
       Acquiring Fund Prospectus and the Registration Statement.

    r. The registration statement on Form N-14 (the "Registration Statement")
       filed with the Securities and Exchange Commission (the "Commission") by
       the Loomis Trust on behalf of the Acquiring Fund and relating to the
       Merger Shares issuable hereunder, and the proxy statement of the
       Acquired Fund relating to the meeting of the Acquired Fund's
       shareholders referred to in Section 7 herein (together with the
       documents incorporated therein by reference, the "Acquired Fund Proxy
       Statement"), on the effective date of the Registration Statement
       (i) complied in all material respects with the provisions of the 1933
       Act, the 1934 Act and the 1940 Act and the rules and regulations
       thereunder and (ii) did not contain any untrue statement of a material
       fact or omit to state a material fact required to be stated therein or
       necessary to make the statements therein not misleading;

                                      4



       and at the time of the shareholders' meeting referred to in Section 7
       and on the Exchange Date, the prospectus which is contained in the
       Registration Statement, as amended or supplemented by any amendments or
       supplements filed with the Commission by the Loomis Trust, and the
       Acquired Fund Proxy Statement did not and will not contain any untrue
       statement of a material fact or omit to state a material fact required
       to be stated therein or necessary to make the statements therein not
       misleading; provided, however, that none of the representations and
       warranties in this subparagraph (r) shall apply to statements in or
       omissions from the Registration Statement or the Acquired Fund Proxy
       Statement made in reliance upon and in conformity with information
       furnished by the Acquired Fund for use in the Registration Statement or
       the Acquired Fund Proxy Statement.

2. Representations, Warranties and Agreements of the Acquired Fund. The Trust,
   and not the individual Trustees and officers thereof, on behalf of the
   Acquired Fund, represents and warrants to and agrees with the Acquiring Fund
   that:

    a. The Acquired Fund is a series of shares of the Trust, a Massachusetts
       business trust duly established and validly existing under the laws of
       the Commonwealth of Massachusetts, and has power to own all of its
       properties and assets and to carry out this Agreement. The Trust is
       qualified as a foreign association in every jurisdiction where required,
       except to the extent that failure to so qualify would not have a
       material adverse effect on the Trust. Each of the Trust and the Acquired
       Fund has all necessary federal, state and local authorizations to own
       all of its properties and assets and to carry on its business as now
       being conducted and to carry out this Agreement.

    b. The Trust is registered under the 1940 Act as an open-end management
       investment company, and such registration has not been revoked or
       rescinded and is in full force and effect.

    c. A statement of assets and liabilities, statement of operations,
       statement of changes in net assets and a schedule of investments
       (indicating their market values) of the Acquired Fund as of and for the
       period ended June 30, 2007 have been furnished to the Acquiring Fund
       prior to the Exchange Date. Such statement of assets and liabilities and
       schedule fairly present the financial position of the Acquired Fund as
       of such date and said statements of operations and changes in net assets
       fairly reflect the results of its operations and changes in net assets
       for the periods covered thereby in conformity with generally accepted
       accounting principles.

    d. Since June 30, 2007, there has not been any material adverse change in
       the Acquired Fund's financial condition, assets, liabilities or business
       (other than changes occurring in the ordinary course of business), or
       any incurrence by the Acquired Fund of indebtedness, except as disclosed
       in writing to the Acquiring Fund. For the purposes of this subsection
       (d) and of Section 9(a) of this Agreement, distributions of net
       investment income and net realized capital gains, changes in portfolio
       securities, changes in the market value of portfolio securities or net
       redemptions shall be deemed to be in the ordinary course of business.

                                      5



    e. The Trust is not in violation in any material respect of any provision
       of its Third Amended and Restated Agreement and Declaration of Trust or
       By-Laws or of any agreement, indenture, instrument, contract, lease or
       other undertaking to which the Trust is a party or by which the Acquired
       Fund is bound, and the execution, delivery and performance of this
       Agreement will not result in any such violation.

    f. The prospectuses and the statement of additional information of the
       Acquired Fund, each dated May 1, 2007, and each as from time to time
       amended or supplemented (collectively, the "Acquired Fund Prospectus"),
       previously furnished to the Acquiring Fund (i) conform in all material
       respects to the applicable requirements of the 1933 Act and (ii) did not
       contain as of such date and do not contain, with respect to the Trust
       and the Acquired Fund, any untrue statement of a material fact or omit
       to state a material fact required to be stated therein or necessary to
       make the statements therein not misleading.

    g. The Acquired Fund's investment operations from inception to the date
       hereof have been in compliance in all material respects with the
       investment policies and investment restrictions set forth in the
       Acquired Fund Prospectus.

    h. At the Exchange Date, the Trust, on behalf of the Acquired Fund, will
       have good and marketable title to its assets to be transferred to the
       Acquiring Fund pursuant to this Agreement and will have full right,
       power and authority to sell, assign, transfer and deliver the
       Investments (as defined below) and any other assets and liabilities of
       the Acquired Fund to be transferred to the Acquiring Fund pursuant to
       this Agreement. At the Exchange Date, subject only to the delivery of
       the Investments and any such other assets and liabilities and payment
       therefor as contemplated by this Agreement, the Acquiring Fund will
       acquire good and marketable title thereto and will acquire the
       Investments and any such other assets and liabilities subject to no
       encumbrances, liens or security interests whatsoever and without any
       restrictions upon the transfer thereof, except as previously disclosed
       in writing to the Acquiring Fund.

    i. There are no material legal, administrative or other proceedings pending
       or, to the knowledge of the Trust or the Acquired Fund, threatened
       against the Trust or the Acquired Fund, which assert liability on the
       part of the Trust or the Acquired Fund. The Acquired Fund knows of no
       facts which might form the basis for the institution of such proceedings
       and is not a party to or subject to the provisions of any order, decree
       or judgment of any court or governmental body which materially and
       adversely affects its business or its ability to consummate the
       transactions herein contemplated.

    j. There are no material contracts outstanding to which the Acquired Fund
       is a party, other than as are or will be disclosed in Acquired Fund
       Prospectus, the registration statement on Form N-1A of the Acquired Fund
       (the "Acquired Fund Registration Statement") or the Acquired Fund Proxy
       Statement.

    k. The Acquired Fund has no known liabilities of a material nature,
       contingent or otherwise, other than those that are shown on the Acquired
       Fund's statement of assets and liabilities as of June 30, 2007, referred
       to above and those incurred in the ordinary course of its business as an
       investment company since such date. Prior to the Exchange Date, the

                                      6



       Acquired Fund will quantify and reflect on its balance sheet all of its
       material known liabilities and will advise the Acquiring Fund of all
       material liabilities, contingent or otherwise, incurred by it subsequent
       to June 30, 2007, whether or not incurred in the ordinary course of
       business.

    l. As of the Exchange Date, the Acquired Fund will have filed all required
       federal and other tax returns and reports (giving effect to extensions)
       which, to the knowledge of the Trust's officers, are required to have
       been filed by the Acquired Fund by such date and has paid or will pay
       all federal and other taxes shown to be due on said returns or on any
       assessments received by the Acquired Fund. All tax liabilities of the
       Acquired Fund have been adequately provided for on its books, and no tax
       deficiency or liability of the Acquired Fund has been asserted, and no
       question with respect thereto has been raised or is under audit, by the
       Internal Revenue Service or by any state, local or other tax authority
       for taxes in excess of those already paid.

    m. The Trust has and, at the Exchange Date, the Trust, on behalf of the
       Acquired Fund, will have, full right, power and authority to sell,
       assign, transfer and deliver the Investments (as defined below) and any
       other assets and liabilities of the Acquired Fund to be transferred to
       the Acquiring Fund pursuant to this Agreement. At the Exchange Date,
       subject only to the delivery of the Investments and any such other
       assets and liabilities as contemplated by this Agreement, the Acquiring
       Fund will acquire the Investments and any such other assets and
       liabilities subject to no encumbrances, liens or security interests
       whatsoever and without any restrictions upon the transfer thereof. As
       used in this Agreement, the term "Investments" shall mean the Acquired
       Fund's investments shown on the schedule of its investments as of
       June 30, 2007, referred to in Section 2(c) hereof, as modified by such
       changes in the portfolio as the Acquired Fund shall make, and changes
       resulting from stock dividends, stock split-ups, mergers and similar
       corporate actions through the Exchange Date.

    n. No registration under the 1933 Act of any of the Investments would be
       required if they were, as of the time of such transfer, the subject of a
       public distribution by either of the Acquiring Fund or the Acquired
       Fund, except as previously disclosed to the Acquiring Fund by the
       Acquired Fund.

    o. No consent, approval, authorization or order of any court or
       governmental authority is required for the consummation by the Acquired
       Fund of the transactions contemplated by this Agreement, except such as
       may be required under the 1933 Act, 1934 Act, the 1940 Act or state
       securities or blue sky laws.

    p. The Acquired Fund qualifies and will at all times through the Exchange
       Date qualify for taxation as a "regulated investment company" under
       Subchapter M of the Code.

    q. At the Exchange Date, the Acquired Fund will have sold such of its
       assets, if any, as are necessary to assure that, after giving effect to
       the acquisition of the assets of the Acquired Fund pursuant to this
       Agreement, the Acquiring Fund will remain a "diversified company" within
       the meaning of Section 5(b)(1) of the 1940 Act and in compliance with
       such other mandatory investment restrictions as are set forth in the
       Acquired Fund Prospectus, as amended through the Exchange Date.

                                      7



    r. To the best of its knowledge, all of the issued and outstanding shares
       of beneficial interest of the Acquired Fund have been offered for sale
       and sold in conformity with all applicable federal and state securities
       laws (including any applicable exemptions therefrom), except as
       previously disclosed to the Acquiring Fund, or the Acquired Fund or its
       investment adviser has taken any action necessary to remedy any prior
       failure to have offered for sale and sold such shares in conformity with
       such laws.

    s. All issued and outstanding shares of the Acquired Fund are, and at the
       Exchange Date will be, duly and validly issued and outstanding, fully
       paid and, except as set forth in the registration statement of the
       Trust, non-assessable by the Acquired Fund. The Acquired Fund does not
       have outstanding any options, warrants or other rights to subscribe for
       or purchase any of the Acquired Fund shares, nor is there outstanding
       any security convertible into any of the Acquired Fund shares except
       that Class B shares of the Acquired Fund are convertible into Class A
       shares of the Acquired Fund in the manner and on the terms described in
       the Acquired Fund Prospectus.

    t. The Acquired Fund Proxy Statement, on the date of its filing
       (i) complied in all material respects with the provisions of the 1933
       Act, the 1934 Act and the 1940 Act and the rules and regulations
       thereunder and (ii) did not contain any untrue statement of a material
       fact or omit to state a material fact required to be stated therein or
       necessary to make the statements therein not misleading; and at the time
       of the shareholders' meeting referred to in Section 7 and on the
       Exchange Date, the Acquired Fund Proxy Statement did not and will not
       contain any untrue statement of a material fact or omit to state a
       material fact required to be stated therein or necessary to make the
       statements therein not misleading; provided, however, that none of the
       representations and warranties in this subsection shall apply to
       statements in or omissions from the Acquired Fund Proxy Statement made
       in reliance upon and in conformity with information furnished by the
       Acquiring Fund for use in the Acquired Fund Proxy Statement.

    u. The Trust has no material contracts or other commitments (other than
       this Agreement and such other contracts as may be entered into in the
       ordinary course of its business) which if terminated may result in
       material liability to the Acquired Fund (or to the Acquiring Fund as a
       result of the transactions contemplated by this Agreement) or under
       which (whether or not terminated) any material payments for periods
       subsequent to the Exchange Date will be due from the Acquired Fund (or
       from the Acquiring Fund as a result of the transactions contemplated by
       this Agreement).

    v. The information provided by the Acquired Fund for use in the
       Registration Statement and Proxy Statement was accurate and complete in
       all material respects when supplied and as of July 3, 2007 was accurate
       and complete in all material respects and complied with federal
       securities and other laws and regulations applicable thereto in all
       material respects.

3. Reorganization.

    a. Subject to the requisite approval of the shareholders of the Acquired
       Fund and to the other terms and conditions contained herein (including
       the Acquired Fund's obligation (if any) to distribute to its
       shareholders all of its investment company taxable income and net
       capital gain as described in Section 8(j) hereof), the Acquired Fund
       agrees to sell, assign, convey, transfer and deliver to the Acquiring
       Fund, and the Acquiring Fund agrees to acquire from the Acquired Fund,
       on the Exchange Date all of the Investments and all of the cash and
       other properties and assets of the Acquired Fund, whether accrued or
       contingent (including cash received by the Acquired Fund upon the
       liquidation of the Acquired Fund of any Acquired Fund investments
       designated by the Acquiring Fund as being unsuitable for it to acquire
       pursuant to the investment restrictions of the Acquiring Fund set forth
       in the Acquiring Fund Prospectus and the Registration Statement), in
       exchange for that number of shares of beneficial interest of the
       Acquiring Fund provided for in Section 4 and the assumption by the
       Acquiring Fund of all of the liabilities of the Acquired Fund, whether
       accrued or contingent, existing at the Valuation Time except for the
       Acquired Fund's liabilities, if any, arising in connection with this
       Agreement. The Acquired Fund will, as soon as practicable after the
       Exchange Date, distribute in complete liquidation all of the Merger
       Shares received by it to the shareholders of the Acquired Fund in
       exchange for their shares of the Acquired Fund.

    b. The Acquired Fund will pay or cause to be paid to the Acquiring Fund any
       interest, cash or such dividends, rights and other payments received by
       it on or after the Exchange Date with respect to the Investments and
       other properties and assets of the Acquired Fund, whether accrued or
       contingent, received by it on or after the Exchange Date. Any such
       distribution shall be deemed included in the assets transferred to the
       Acquiring Fund at the Exchange Date and shall not be separately valued
       unless the securities in respect of which such distribution is made
       shall have gone "ex" such distribution prior to the Valuation Time, in
       which case any such distribution which remains unpaid at the Exchange
       Date shall be included in the determination of the value of the assets
       of the Acquired Fund acquired by the Acquiring Fund.

    c. The Valuation Time shall be 4:00 p.m. Eastern time on the Exchange Date
       or such other time as may be mutually agreed upon in writing by the
       parties hereto (the "Valuation Time").

4. Exchange Date; Valuation Time. On the Exchange Date, the Acquiring Fund will
   deliver to the Acquired Fund a number of full and fractional Merger Shares
   having an aggregate net asset value equal, in the case of each such class of
   Merger Shares, to the value of the assets of the Acquired Fund attributable
   to the same class of shares of the Acquired Fund on such date less the value
   of the liabilities attributable to the same class of shares of the Acquired
   Fund assumed by the Acquiring Fund on that date, determined as hereinafter
   provided in this Section 4.

                                      9



    a. The net asset value of the Merger Shares to be delivered to the Acquired
       Fund, the value of the assets attributable to the shares of the Acquired
       Fund, and the value of the liabilities of the Acquired Fund to be
       assumed by the Acquiring Fund, shall in each case be determined as of
       the Valuation Time.

    b. The net asset value of the Merger Shares shall be computed in the manner
       set forth in the Acquiring Fund Prospectus. The value of the assets and
       liabilities of the Acquired Fund shall be determined by the Acquiring
       Fund, in cooperation with the Acquired Fund, pursuant to procedures
       which the Acquiring Fund would use in determining the fair market value
       of the Acquiring Fund's assets and liabilities.

    c. No adjustment shall be made in the net asset value of either the
       Acquired Fund or the Acquiring Fund to take into account differences in
       realized and unrealized gains and losses.

    d. The Acquiring Fund shall issue the Merger Shares to the Acquired Fund.
       The Acquired Fund shall promptly distribute the Merger Shares to the
       shareholders of the Acquired Fund by establishing open accounts for each
       Acquired Fund shareholder on the transfer records of the Acquiring Fund.
       Certificates representing Merger Shares will not be issued to Acquired
       Fund shareholders.

    e. The Acquiring Fund shall assume all liabilities of the Acquired Fund,
       whether accrued or contingent, in connection with the acquisition of
       assets and subsequent liquidation and dissolution of the Acquired Fund
       or otherwise, except for the Acquired Fund's liabilities, if any,
       arising pursuant to this Agreement.

5. Expenses, Fees, etc.

    a. Except as otherwise provided in this Section 5, Natixis Asset Management
       Advisors, L.P., by countersigning this Agreement, agrees that it will
       bear any and all costs and expenses of the transaction incurred by the
       Acquiring Fund and the Acquired Fund; provided, however, that the
       Acquiring Fund and the Acquired Fund will each pay any brokerage
       commissions, dealer mark-ups and similar expenses ("Portfolio Expenses")
       that it may incur in connection with the purchases or sale of portfolio
       securities; and provided further that, the Acquiring Fund will pay all
       governmental fees required in connection with the registration or
       qualification of the Merger Shares under applicable state and federal
       laws.

    b. In the event the transactions contemplated by this Agreement are not
       consummated, then Natixis Asset Management Advisors, L.P. agrees that it
       shall bear all of the costs and expenses (other than Portfolio Expenses)
       incurred by both the Acquiring Fund and the Acquired Fund in connection
       with such transactions.

    c. Notwithstanding any other provisions of this Agreement, if for any
       reason the transactions contemplated by this Agreement are not
       consummated, neither the Acquiring Fund nor the Acquired Fund shall be
       liable to the other for any damages resulting therefrom, including,
       without limitation, consequential damages, except as specifically set
       forth above.

                                      10



    d. Notwithstanding any of the foregoing, costs and expenses will in any
       event be paid by the party directly incurring them if and to the extent
       that the payment by another party of such costs and expenses would
       result in the disqualification of such party as a "regulated investment
       company" within the meaning of Subchapter M of the Code.

6. Exchange Date. Delivery of the assets of the Acquired Fund to be
   transferred, assumption of the liabilities of the Acquired Fund to be
   assumed, and delivery of the Merger Shares to be issued shall be made at the
   offices of Natixis Asset Management Advisors, L.P., 399 Boylston Street,
   Boston, MA 02116, as of the close of business on October 26, 2007, or at
   such other time and date agreed to by the Acquiring Fund and the Acquired
   Fund, the date and time upon which such delivery is to take place being
   referred to herein as the "Exchange Date."

7. Meeting of Shareholders; Dissolution.

    a. The Trust, on behalf of the Acquired Fund, shall call a meeting of the

       Acquired Fund shall not conduct any business except in connection with
       its liquidation and dissolution.

    c. The Acquiring Fund shall, after the preparation and delivery to the
       Acquiring Fund by the Acquired Fund of a preliminary version of the

       Registration Statement, file the Registration Statement with the

       cooperate with the other, and each will furnish to the other the
       information relating to itself required by the 1933 Act, the 1934 Act
       and the 1940 Act and the rules and regulations thereunder to be set

       changes in the market value of the Investments and other assets of the
       Acquired Fund, or changes due to dividends paid, and a certificate of
       both such officers representing and warranting

       provisions and qualifying tests for regulated investment companies and
       that, in the course of such procedures, nothing came to their attention
       which caused them to believe that the Acquired Fund (i) would not
       qualify as a regulated investment company for federal, state, local or
       other income tax purposes or (ii) would owe any federal, state or local
       income tax or excise tax, in each case for both the taxable year ended

       Acquiring Fund, is a valid and binding obligation of the Trust and the
       Acquired Fund enforceable against the Trust and the Acquired Fund in
       accordance with its terms, except as may be limited by bankruptcy,
       insolvency, reorganization or other similar laws affecting the

       principles; (iii) the Trust, on behalf of the Acquired Fund, has power
       to sell, assign, convey, transfer and deliver the assets contemplated

       provision of any agreement known to such counsel to which the Trust or
       the Acquired Fund is a party or by which it is bound or, to the
       knowledge of such counsel, result in the acceleration of any penalty
       under any agreement, judgment or decree to which the Trust or the
       Acquired Fund is party or by which either of them is bound, it being

       financial data, or as to the information relating to the Acquired Fund,
       the Acquired Fund Proxy Statement, or the Registration Statement, and

       current administrative rules and court decisions, for federal income tax

       the 1933 Act, the 1934 Act and the 1940 Act and assuming due
       authorization, execution and delivery of this Agreement by the Trust on
       behalf of the Acquired Fund, is a valid and binding obligation of the
       Loomis Trust and the Acquiring Fund enforceable against the Loomis Trust
       and the Acquiring Fund in accordance with its terms, except as the same
       may be limited by bankruptcy, insolvency, reorganization or other
       similar laws affecting the enforcement of creditors' rights generally
       and other equitable principles; (iv) the execution and delivery of this
       Agreement did not, and the consummation of the transactions contemplated
       hereby will not, violate the First Amended and Restated Agreement and
       Declaration of Trust or By-Laws of the Loomis Trust, or any provision of
       any agreement known to such counsel to which the Loomis Trust or the
       Acquiring Fund is a party or by which it is bound or, to the knowledge
       of such counsel, result in the acceleration of any obligation or the
       imposition of any penalty under any agreement, judgment or decree to
       which the Loomis Trust or the Acquiring Fund is party or by which either
       of them is bound, it being understood that with respect to investment
       restrictions as contained in the First Amended and Restated Agreement
       and Declaration of Trust, By-Laws or then-current prospectuses

                                      16



       or statement of additional information of the Loomis Trust, such counsel
       may rely upon a certificate of an officer of the Loomis Trust; (v) to
       the knowledge of such counsel, no consent, approval, authorization or
       order of any court or governmental authority is required for the
       consummation by the Loomis Trust on behalf of the Acquiring Fund of the
       transactions contemplated herein, except such as have been obtained
       under the 1933 Act, the 1934 Act and the 1940 Act and such as may be
       required under state securities or "Blue Sky" laws; (vi) the Loomis
       Trust is registered with the Commission as an investment company under
       the 1940 Act; and (vii) to the knowledge of such counsel, no litigation
       or administrative proceeding or investigation of or before any court or
       governmental body is presently pending or threatened as to the Loomis
       Trust or the Acquiring Fund or any of their properties or assets that
       challenges or seeks to prohibit, restrain or enjoin the transactions
       contemplated by this Agreement. Such opinion may state that such counsel
       does not express any opinion or belief as to the financial statements or
       other financial data, or as to the information relating to the Acquired
       Fund, contained in the Acquired Fund Proxy Statement or the Registration
       Statement, and that such opinion is solely for the benefit of the
       Acquired Fund, its Trustees and its officers.

    f. That the Acquired Fund shall have received an opinion of Ropes &
       Gray LLP, dated the Exchange Date (which opinion would be based upon
       certain factual representations and subject to certain qualifications),
       in form satisfactory to the Acquired Fund to the effect that, on the
       basis of the existing provisions of the Code, current administrative
       rules and court decisions, for federal income tax purposes: (i) the
       transactions contemplated by this Agreement will constitute a
       reorganization within the meaning of Section 368(a) of the Code, and the
       Acquiring Fund and the Acquired Fund will each be "a party to the
       reorganization" within the meaning of Section 368(b) of the Code;
       (ii) under Section 361 of the Code, no gain or loss will be recognized
       by the Acquired Fund (x) upon the transfer of its assets to the
       Acquiring Fund in exchange for the Merger Shares and the assumption by
       the Acquiring Fund of the liabilities of the Acquired Fund as
       contemplated in Section 3 hereof or (y) upon the distribution of the
       Merger Shares to the shareholders of the Acquired Fund as contemplated
       in Section 3 hereof; (iii) under Section 354 of the Code, no gain or
       loss will be recognized by shareholders of the Acquired Fund on the
       distribution of Merger Shares to them in exchange for their shares of
       the Acquired Fund; (iv) under Section 358 of the Code, the aggregate tax
       basis of the Merger Shares that the Acquired Fund's shareholders receive
       in place of their Acquired Fund shares will be the same as the aggregate
       tax basis of the Acquired Fund shares surrendered in exchange therefor;
       and (v) under Section 1223(1) of the Code, an Acquired Fund's
       shareholder's holding period for the Merger Shares received pursuant to
       the Agreement will be determined by including the holding period for the
       Acquired Fund shares exchanged for the Merger Shares, provided that the
       shareholder held the Acquired Fund shares as a capital asset.

    g. That all actions taken by the Loomis Trust on behalf of the Acquiring
       Fund in connection with the transactions contemplated by this Agreement
       and all documents incidental thereto shall be satisfactory in form and
       substance to the Acquired Fund and Ropes & Gray LLP.

                                      17



    h. That the Loomis Trust shall have received from the Commission and any
       relevant state securities administrator such order or orders as are
       reasonably necessary or desirable under the 1933 Act, the 1934 Act, the
       1940 Act and any applicable state securities or blue sky laws in
       connection with the transactions contemplated hereby, and that all such
       orders shall be in full force and effect.

    i. That this Agreement shall have been adopted and the transactions
       contemplated hereby shall have been approved by the requisite votes of
       the holders of the outstanding shares of beneficial interest of the
       Acquired Fund entitled to vote.

    j. That the Registration Statement on Form N-1A of the Loomis Trust, with
       respect to the Acquiring Fund, shall have become effective under the
       1933 Act, and no stop order suspending such effectiveness shall have
       been instituted or, to the knowledge of the Loomis Trust or the
       Acquiring Fund, threatened by the Commission.

10. Indemnification.

    a. The Acquired Fund shall indemnify and hold harmless, out of the assets
       of the Acquired Fund but no other assets, the Loomis Trust and the
       Trustees and officers of the Loomis Trust (for purposes of this
       Section 10(a), the "Loomis Trust Indemnified Parties") against any and
       all expenses, losses, claims, damages and liabilities at any time
       imposed upon or reasonably incurred by any one or more of the Loomis
       Trust Indemnified Parties in connection with, arising out of or
       resulting from any claim, action, suit or proceeding in which any one or
       more of the Loomis Trust Indemnified Parties may be involved or with
       which any one or more of the Loomis Trust Indemnified Parties may be
       threatened by reason of any untrue statement or alleged untrue statement
       of a material fact relating to the Trust or the Acquired Fund contained
       in this Agreement, the Registration Statement, the Acquired Fund
       Prospectus or the Acquired Fund Proxy Statement or any amendment or
       supplement to any of the foregoing, or arising out of or based upon the
       omission or alleged omission to state in any of the foregoing a material
       fact relating to the Trust or the Acquired Fund required to be stated
       therein or necessary to make the statements relating to the Trust or the
       Acquired Fund therein not misleading, including, without limitation, any
       amounts paid by any one or more of the Loomis Trust Indemnified Parties
       in a reasonable compromise or settlement of any such claim, action, suit
       or proceeding, or threatened claim, action, suit or proceeding made with
       the consent of the Trust or the Acquired Fund. The Loomis Trust
       Indemnified Parties will notify the Trust and the Acquired Fund in
       writing within ten days after the receipt by any one or more of the
       Loomis Trust Indemnified Parties of any notice of legal process or any
       suit brought against or claim made against such Loomis Trust Indemnified
       Party as to any matters covered by this Section 10(a). The Acquired Fund
       shall be entitled to participate at its own expense in the defense of
       any claim, action, suit or proceeding covered by this Section 10(a), or,
       if it so elects, to assume at its expense by counsel satisfactory to the
       Loomis Trust Indemnified Parties the defense of any such claim, action,
       suit or proceeding, and if the Acquired Fund elects to assume such
       defense, the Loomis Trust Indemnified Parties shall be entitled to
       participate in the defense of any such claim, action, suit or proceeding
       at their expense. The Acquired Fund's obligation under this
       Section 10(a) to indemnify and hold harmless the Loomis Trust
       Indemnified Parties shall

                                      18



       constitute a guarantee of payment so that the Acquired Fund will pay in
       the first instance any expenses, losses, claims, damages and liabilities
       required to be paid by it under this Section 10(a) without the necessity
       of the Loomis Trust Indemnified Parties' first paying the same.

    b. The Acquiring Fund shall indemnify and hold harmless, out of the assets
       of the Acquiring Fund but no other assets, the Trust and the Trustees
       and officers of the Trust (for purposes of this Section 10(b), the
       "Trust Indemnified Parties") against any and all expenses, losses,
       claims, damages and liabilities at any time imposed upon or reasonably
       incurred by any one or more of the Trust Indemnified Parties in
       connection with, arising out of, or resulting from any claim, action,
       suit or proceeding in which any one or more of the Trust Indemnified
       Parties may be involved or with which any one or more of the Trust
       Indemnified Parties may be threatened by reason of any untrue statement
       or alleged untrue statement of a material fact relating to the Acquiring
       Fund contained in this Agreement, the Registration Statement, the
       Acquiring Fund Prospectus or the Acquired Fund Proxy Statement or any
       amendment or supplement to any thereof, or arising out of, or based
       upon, the omission or alleged omission to state in any of the foregoing
       a material fact relating to the Loomis Trust or the Acquiring Fund
       required to be stated therein or necessary to make the statements
       relating to the Loomis Trust or the Acquiring Fund therein not
       misleading, including, without limitation, any amounts paid by any one
       or more of the Trust Indemnified Parties in a reasonable compromise or
       settlement of any such claim, action, suit or proceeding, or threatened
       claim, action, suit or proceeding made with the consent of the Loomis
       Trust or the Acquiring Fund. The Trust Indemnified Parties will notify
       the Loomis Trust and the Acquiring Fund in writing within ten days after
       the receipt by any one or more of the Trust Indemnified Parties of any
       notice of legal process or any suit brought against or claim made
       against such Trust Indemnified Party as to any matters covered by this
       Section 10(b). The Acquiring Fund shall be entitled to participate at
       its own expense in the defense of any claim, action, suit or proceeding
       covered by this Section 10(b), or, if it so elects, to assume at its
       expense by counsel satisfactory to the Trust Indemnified Parties the
       defense of any such claim, action, suit or proceeding, and, if the
       Acquiring Fund elects to assume such defense, the Trust Indemnified
       Parties shall be entitled to participate in the defense of any such
       claim, action, suit or proceeding at their own expense. The Acquiring
       Fund's obligation under this Section 10(b) to indemnify and hold
       harmless the Trust Indemnified Parties shall constitute a guarantee of
       payment so that the Acquiring Fund will pay in the first instance any
       expenses, losses, claims, damages and liabilities required to be paid by
       it under this Section 10(b) without the necessity of the Trust
       Indemnified Parties' first paying the same.

11. No Broker, etc. Each of the Acquired Fund and the Acquiring Fund represents
    that there is no person who has dealt with it or the Trust or the Loomis
    Trust, respectively, who, by reason of such dealings, is entitled to any
    broker's or finder's or other similar fee or commission arising out of the
    transactions contemplated by this Agreement.

                                      19



12. Termination. The Acquired Fund and the Acquiring Fund may, by mutual
    consent of the trustees on behalf of each Fund, terminate this Agreement,
    and the Acquired Fund or the Acquiring Fund, after consultation with
    counsel and by consent of its Trustees or an officer authorized by such
    Trustees, may waive any condition to its respective obligations hereunder.
    If the transactions contemplated by this Agreement have not been
    substantially completed by December 31, 2007, this Agreement shall
    automatically terminate on that date unless a later date is agreed to by
    the Acquired Fund and the Acquiring Fund.

13. Covenants, etc. Deemed Material. All covenants, agreements, representations
    and warranties made under this Agreement and any certificates delivered
    pursuant to this Agreement shall be deemed to have been material and relied
    upon by each of the parties, notwithstanding any investigation made by them
    or on their behalf.

14. Rule 145. Pursuant to Rule 145 under the 1933 Act, the Acquiring Fund will,
    in connection with the issuance of any Merger Shares to any person who at
    the time of the transaction contemplated hereby is deemed to be an
    affiliate of a party to the transaction pursuant to Rule 145(c), cause to
    be affixed upon the certificates issued to such person (if any) a legend as
    follows:

   "THESE SHARES MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT TO LOOMIS
   SAYLES VALUE FUND OR ITS PRINCIPAL UNDERWRITER UNLESS (i) A REGISTRATION
   STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE SECURITIES ACT OF
   1933, AS AMENDED, OR (ii) IN THE OPINION OF COUNSEL REASONABLY SATISFACTORY
   TO THE FUND SUCH REGISTRATION IS NOT REQUIRED."

   and, further, the Acquiring Fund will issue stop transfer instructions to
   the Acquiring Fund's transfer agent with respect to such shares. The
   Acquired Fund will provide the Acquiring Fund on the Exchange Date with the
   name of any Acquired Fund shareholder who is to the knowledge of the
   Acquired Fund an affiliate of the Acquired Fund on such date.

15. Sole Agreement; Amendments; Governing Law. This Agreement supersedes all
    previous correspondence and oral communications between the parties
    regarding the subject matter hereof, constitutes the only understanding
    with respect to such subject matter, may not be changed except by a letter
    of agreement signed by each party hereto, and shall be construed in
    accordance with and governed by the laws of the Commonwealth of
    Massachusetts.
