SERVICES AGREEMENT FOR MONEY MARKET STRESS TESTING

This Services Agreement for Money Market Stress Testing is effective as of May 3, 2010 by and between Investor Analytics LLC (“IA”) and Natixis Cash Management Trust – Money Market Series (“Client”).

1. BACKGROUND.

Investor Analytics is a Software-as-a-Service Provider that offers Internet-based reporting of its analyses of financial portfolios. This Agreement relates to (a) the configuration by IA of its money market stress test protocol (the “IA Service”) for use by Client, including its officers, investment adviser and sub-adviser (collectively the Client or “Users”) and (b) use of the IA Service by Users in connection with the management of the Client. In consideration of the mutual covenants contained in this Agreement, IA and Client agree as follows:

2. SERVICES BY IA.

(a) Client Site Configuration. IA will provide to Client access to IA’s Internet site, and provide for Client at such site a password protected web page containing a downloadable PDF report which will be delivered by PDF download of the IA Service (the “Client Site”). The specifications for the Client Site are set forth on Schedule 1 attached hereto, together with the cost, timetable and payment schedule for integrating Client data into and maintaining the Client Site. IA will use all commercially reasonable efforts, subject to Section 11(j), to conform to the timetable. To the extent that Client desires to change any of the Specifications after the date hereof, IA agrees to evaluate its ability to make the requested change, and to prepare an estimate of the anticipated time and cost (if any) of such change. After receiving IA’s estimate of the time and cost for the change, Client will notify IA whether it desires to

proceed with such change. If Client desires to proceed with the change, Schedule 1 will be amended accordingly.

(b) Client Site Maintenance. Once operational, IA will maintain the Client Site for the annual fee set forth on Schedule 1 attached hereto, which fee can be changed from time to time by IA upon 90 days’ prior written notice to Client.

(c) Portfolio Analysis. If requested by Client and agreed to by IA, IA will provide additional specific risk transparency services for an additional fee. The nature of any such services, and the related fees, will be set forth on Schedule 1 attached hereto, as the same may from time to time be amended by the mutual written agreement of the parties. All services listed on Schedule 1 will be bound by this Agreement.

3. ACCESS TO THE CLIENT SITE; DISSEMINATION OF INFORMATION.

(a) Grant of Access. IA hereby grants Client a non-transferable and non-exclusive right for Users to access the Service, subject to Client’s compliance with all terms and conditions of this Agreement.

(b) Responsibility for Users. Client hereby accepts responsibility for the acts and omissions of all of its users.

(c) Ownership. Client acknowledges that the technologies and methodologies of the IA Service and those incorporated into the Client Site have been developed by IA at significant expense, and are proprietary to and owned by IA. Client will not (i) permit any third party, including Client’s customers, access to the Client Site unless expressly called for in Schedule 1 provided for in writing by IA, (ii) utilize the Client Site to provide services to or

for any third party or portfolio other than the Client, or (iii) knowingly damage or compromise IA’s patent, copyright, trademark, trade secret or other proprietary interests in the IA Service, the Client Site, and the technologies embedded therein.

(d) Third Party Information Providers. Client acknowledges that IA obtains certain market and other information from third party providers and the use of such information is limited by the agreements between IA and such information providers. Accordingly, Client must obtain the prior written consent of IA prior to disseminating to any third party, including Client’s customers, any information from the Client Site, or permitting any such party to have direct access to the Client Site. IA may withhold such consent in its sole discretion, and it will do so if the consent of the appropriate information provider cannot be obtained. Notwithstanding the above, IA hereby consents to Client sharing such information with its trustees, officers, investment adviser and sub-adviser.

(e) Input of Portfolio Information. Client will be responsible for the electronic delivery of all portfolio files to IA in a format and delivery method approved by IA. Once obtained and approved, IA will be responsible for the input of all such data.

(b) Breach. In the event Client defaults in the payment of any fee due to IA under this Agreement, and such default is not cured within 10 days after notice thereof is delivered by IA, IA may suspend Client’s password and deny access to the Client Site until such payment is made in full. Suspending Client’s access to the Client Site will be in addition to, and not in lieu of, any other remedy that may be available to IA as a result of such breach.

5. OTHER ACTIVITIES OF IA.

Nothing contained herein will prohibit IA or any member, manager, officer, employee or agent of IA, or any individual

or organization associated or affiliated with any of the foregoing (collectively, “IA Affiliates”), from (i) acting in any capacity, including as a service provider, investment manager or advisor to any individual or organization, (ii) from participating in any entity, including service providers, investment managers or advisor or (iii) from making investments in any companies, including companies which compete with Client.
