Dealer Agreement

This dealer agreement (“Dealer Agreement”) is entered into between Natixis Distribution, LLC (formerly Natixis Distribution, L.P.) (“our”, “us”, or “we”) and the undersigned company (“you”). We offer to sell to you shares of each of the mutual funds distributed by us (the “Funds” and each a “Fund”), for each of which we serve as principal underwriter as defined in the Investment Company Act of 1940, as amended (the “Act”), and from which we have the right to purchase shares.1 Shares are offered pursuant to the then current prospectus, including any supplements or amendments thereto, of each of the Funds (the “Prospectus,” which term as hereinafter used shall include the Statement of Additional Information of the Fund).

With respect to each of the Funds (except for Section 5, which applies only with respect to each Fund having in effect from time to time a service plan, service and distribution plan or other plan adopted pursuant to Rule 12b-1 under the Act, each a “Plan” and together the “Plans”):

1. For all sales of shares of the Funds you shall act as dealer for your own account, and in no transaction shall you have any authority to act as agent, except as limited agent for purposes of receiving and transmitting orders and instructions regarding the purchase, exchange and redemption of shares of your customers and employees, with no authority to otherwise act as agent for any Fund or for us.

2. You or your designated agent agree to obtain and provide to your customers the Prospectus(es) of the applicable Fund(s) together with any supplemental sales literature you provide. You agree not to purchase any Fund shares for any customer, unless you deliver or cause to be delivered to such customer, at or prior to the time of such purchase, a copy of the Prospectus of the applicable Fund, or the Prospectus of the applicable Fund. You hereby represent that you understand your obligation to deliver a Prospectus to customers who purchase Fund shares pursuant to federal securities laws and you have taken all necessary steps to comply with such Prospectus delivery requirements.

3. Orders received from you will be accepted by us only at the public offering price applicable to each order, except for transactions to which a reduced offering price applies as provided in the Prospectus of the Fund(s). The minimum dollar purchase of shares of each Fund by any investor shall be the applicable minimum amount described in the Prospectus of the Fund and no order for less than such amount will be accepted hereunder. The public offering price shall be the net asset value per share plus the sales charge, if any, applicable to the transaction, expressed as a percentage of the public offering price, as determined and effective as of the time specified in the Prospectus of the Fund(s). The procedures relating to the handling of orders shall be subject to any instructions that we shall forward from time to time to you. All orders are subject to acceptance or rejection by us, or our designated agent, in our sole discretion. You hereby agree to comply with attached Appendix A, Policies and Procedures with Respect to Mutual Fund Trading, as well as with the terms of the Prospectus and the policies and procedures of the Funds. You understand that in recommending the purchase, sale or exchange of any Fund shares to your customers, you must have reasonable grounds for believing that such recommendation is suitable for such customer.

4. The sales charge applicable to any sale of Fund shares by you and the dealer concession or commission applicable to any order from you for the purchase of Fund shares accepted by us shall be set forth in the Prospectus of the Fund. You shall notify us if you are not eligible to receive a dealer concession or commission. You may be deemed to be an underwriter in connection with sales by you of shares of the Fund where you receive all or substantially all of the sales charge as set forth in the Fund’s Prospectus, and therefore you may be subject to applicable provisions of the Securities Act of 1933.

1

(a) We are entitled to a contingent deferred sales charge (“CDSC”) on redemptions of applicable classes of shares of the Funds, as described in the Prospectus. You agree that you will sell shares subject to a CDSC and that are to be held in omnibus accounts only if you are a NETWORKING participant with the National Securities Clearing Corporation and if such accounts are established pursuant to a NETWORKING Agreement.

(b) Reduced sales charges or no sales charge may apply to certain transactions, including under letter of intent, combined purchases or investments, reinvestment of dividends and distributions, repurchase privilege, unit investment trust distribution reinvestment or other programs, as described in the Prospectus of the Fund(s). To obtain any such reductions, you must notify us when the sale that would qualify for such reduction takes place.

5. Rule 12b-1 Plans. The substantive provisions of this Section 5 have been adopted pursuant to the Plans.

(a) You agree to provide (i) for the Funds with a service plan, personal services to investors in shares of the Funds and/or services related to the maintenance of shareholder accounts, and (ii) for those Funds with a service and distribution plan, both personal services to investors in shares of the Funds and/or services related to the maintenance of shareholder accounts and also distribution and marketing services in the promotion of Fund shares. As compensation for these services, we shall pay you, as agent, upon receipt by us from the Fund(s), a quarterly service fee or service fee and distribution fee based on the average daily net asset value of Fund shares at the rate set forth with respect to the relevant Class(es) of shares of the Fund(s) in the Prospectus. This fee will be based on the average daily net asset value of Fund shares that are owned of record by your firm as nominee for your customers or that are owned by those shareholders whose records, as maintained by the Fund or its agent, designate your firm as the shareholder’s dealer of record. Normally, payment of such fee to you shall be made within forty-five (45) days after the close of each quarter for which such fee is payable provided, however, that any other provision of this Dealer Agreement or the Prospectuses to the contrary notwithstanding, we shall not have any obligation whatsoever to pay any amount of distribution and/or service fee with respect to shares of any Fund except to the extent, and only to the extent, that we have actually received payment of at least such amount of distribution and/or service fee from the Funds with respect to such shares pursuant to a Plan in consideration of you furnishing distribution and client services hereunder with respect to your customers that own such class of shares of such Fund, it being understood that our liability to you in respect of such fees is limited solely to the proceeds of such fees received by us from the Funds.

(b) You shall furnish us and the Fund with such information as shall reasonably be requested by the Trustees of the Fund with respect to the fees paid to you pursuant to this Section 5 and you shall notify us if you are not eligible to receive 12b-1 fees, including without limitation by reason of your failure to provide the services as required in this Section 5.

(c) The provisions of this Section 5 may be terminated by the vote of a majority of the Trustees of the Funds who are not interested persons of the Funds and who have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan, or by a vote of a majority of the Fund’s outstanding shares, on sixty (60) days’ written notice, without payment of any penalty. Such provisions will be terminated also by any act that terminates either the Fund’s Distribution Contract or Underwriting Agreement with us, or this Dealer Agreement under Section 16 hereof or otherwise and shall terminate automatically in the event of the assignment (as that term is defined in the Act) of this Dealer Agreement.

(d) The provisions of the Distribution Contract or Underwriting Agreement between the Fund and us, insofar as they relate to the Plan, are incorporated herein by reference. The provisions of this Section 5 shall continue in full force and effect only so long as the continuance of the Plan, the Distribution Contract or Underwriting Agreement and these provisions are approved at least annually by a vote of the Trustees, including a majority of the Trustees who are not interested persons of the Fund and who have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan, cast in person at a meeting called for the purpose of voting thereon.

6. You agree to purchase Fund shares only from us or from your customers. If you purchase Fund shares from us, you agree that all such purchases shall be made only: (a) to cover orders already received by you from your customers; (b) for shares being acquired by your customers pursuant to either the exchange privilege or the reinvestment privilege, as described in the Prospectus of the Fund; or (c) for your own bona fide investment. If you purchase shares from your customers, you agree to pay such customers not less than the applicable redemption price next quoted by the Fund pursuant to the procedures set forth in the Prospectus of the Fund.

7. You shall sell shares only: (a) to customers at the applicable public offering price, except for shares being acquired by your customers at net asset value as described in the Prospectus of the Fund, and (b) to us as agent for the Fund at the redemption price. In such a sale to us, you may act either as principal for your own account or as agent for your customer. If

2

you act as principal for your own account in purchasing shares for resale to us, you agree to pay your customer not less than the price that you receive from us. If you act as agent for your customer in selling shares to us, you agree not to charge your customer more than a fair commission or fee for handling the transaction, except that you agree to receive no compensation of any kind based on the reinvestment of redemption or repurchase proceeds pursuant to the repurchase privilege, as described in the Prospectus of the Fund.

8. You hereby certify that all of your customers’ taxpayer identification numbers (“TIN”) or social security numbers (“SSN”) furnished to us by you are correct and that you will not open an account without providing us with the customer’s TIN or SSN. You agree to comply with the provisions of Appendix B, Policies and Procedures with Respect to Rule 22c-2.

9. You hereby acknowledge that, in the performance of the services contemplated by this Dealer Agreement, you use or have access to records, systems, or operations that include, in tangible or electronic form, information relating to your customers such as their name, address (including email address), phone number, account number, SSN, drivers license number, date of birth, account activity, investments, and other nonpublic personal information (including consumer reports) (collectively, “Personal Information” or “Customer Data”), which is subject to the requirements of the Gramm-Leach Bliley Act and Regulation S-P thereunder promulgated by the Securities and Exchange Commission, as from time to time amended, and other federal and state laws and regulations applicable to the management, use, disposal, and safekeeping of Personal Information and/or Customer Data as well as laws and regulations relating to “know your customer,” anti-money laundering, and similar federal and state regulatory requirements (collectively “Privacy Laws”). You agree to comply with all applicable Privacy Laws relating to Personal Information and Customer Data and to cooperate with us in enabling us to satisfy our regulatory requirements relating to Personal Information.

10. You shall not withhold placing with us orders received from your customers so as to profit yourself as a result of such withholding; e.g., by a change in the net asset value from that used in determining the public offering price to your customers.

11. We will not accept from you any conditional orders for shares.

12. If any Fund shares sold to you or your customers under the terms of this Dealer Agreement are redeemed by the Fund or repurchased by us as agent for the Fund within seven (7) business days after the date of our confirmation of the original purchase by you or your customers, it is agreed that you shall forfeit your right to any dealer concession or commission received by you on such Fund shares. We will notify you of any such repurchase or redemption within ten (10) business days after the date thereof and you shall forthwith refund to us the entire concession or commission allowed or paid to you on such sale. We agree, in the event of any such repurchase or redemption, to refund to the Fund the portion of the sales charge, if any, retained by us and, upon receipt from you of the concession allowed to you on any Fund shares, to pay such refund forthwith to the Fund.

13. Payment for Fund shares sold to you shall be made on or before the settlement date specified in our confirmation, at the office of our clearing agent, and by check payable to the order of the Fund, which reserves the right to delay issuance, redemption or transfer of shares until such check has cleared. If such payment and all necessary applications and documents are not received by us, we reserve the right, without notice, forthwith either to cancel the sale, or at our option, sell the shares ordered back to the Fund, in which case you shall bear any loss resulting from your failure to make payment as aforesaid.

14. You will also act as principal in all purchases by a shareholder for whom you are the dealer of record of Fund shares with respect to payments sent directly by such shareholder to the Shareholder Services and Transfer Agent (the “TA”) specified in the Prospectus of the Fund, and you authorize and appoint the TA to execute and confirm such purchases to such shareholders on your behalf. Upon receipt of payment from the Funds, we, as agent, will remit to you, no less frequently than monthly, the amount of any concessions due with respect to such purchases, except that no concessions will be paid to you on any transaction for which your net sales concession is less than $5.00 in any payment cycle. You also represent that with respect to all such direct purchases by such shareholder, you may lawfully sell shares of such Fund in the state designated as such shareholder’s record address.

15. No person is authorized to make any representations concerning shares of the Funds except those contained in the Prospectuses of the Funds and in sales literature issued by us supplemental to such Prospectuses or approved in writing by us. In purchasing shares from us, you shall rely solely on the representations contained in such Prospectuses and such sales literature. We will furnish you with additional copies of such Prospectuses and such sales literature and other releases and information issued by us in reasonable quantities upon request.

(b) You shall indemnify and hold us (and our directors, officers, employees, controlling persons and agents) and the Fund and its Trustees and officers harmless from and against any and all losses, claims, liabilities and expenses (including reasonable attorneys’ fees) (“Losses”) incurred by us or any of them arising out of (i) your dissemination of information regarding any Fund that is alleged to contain an untrue statement of material fact or any omission of a material fact necessary in order to make the statements made, in light of the circumstances under which they were made, not misleading and that was not published or provided to you by or on behalf of us, or accurately derived from information published or provided by or on behalf of us or any of our Affiliates, (ii) any breach by you of any representation, warranty or agreement contained in this Dealer Agreement, (iii) any act or omission, including without limitation any material misstatement by you in connection with any orders or solicitation of orders for, or transactions in, shares of the Funds, or (iv) any willful misconduct or negligence on your part in the performance of, or failure to perform, your obligations under this Dealer Agreement, except to the extent such losses are caused by our breach of this Dealer Agreement or our willful misconduct or negligence in the performance, or failure to perform, our obligations under this Dealer Agreement.

During the period covered by this undertaking, the expense cap arrangement set forth above for each of the Funds may only be modified by a majority vote of the “non-interested” Trustees of the Trust affected.

For purposes of determining any such waiver or expense reimbursement, expenses shall not reflect the application of balance credits made available by the Funds’ custodian or arrangements under which broker-dealers that execute portfolio transactions for the Funds agree to bear some portion of the Funds’ expenses.

We understand and intend that you will rely on this undertaking in preparing and filing the Registration Statements on Form N-1A for the above referenced Funds with the Securities and Exchange Commission, in accruing each Fund’s expenses for purposes of calculating its net asset value per share and for other purposes permitted under Form N-1A and/or the Investment Company Act of 1940, as amended, and expressly permit you to do so.
