3. Management.  Subject always to the supervision of Trust's Board of Trustees and the Adviser, Sub-Adviser will furnish an investment program in respect of, and make investment decisions for, all assets of the Funds and place all orders for the purchase and sale of securities, all on behalf of the Funds. In the performance of its duties, Sub-Adviser will satisfy its fiduciary duties to the Funds (as set forth below), and will monitor the Funds' investments, and will comply with the stated investment objectives, policies and restrictions of the Funds as described in the Prospectus and Statement of Additional Information. Sub-Adviser and Adviser will each make its officers and employees available to the other from time to time at reasonable times to review investment policies of the Funds and to consult with each other regarding the investment affairs of the Funds. Sub-Adviser will report to the Board of Trustees and to Adviser with respect to the implementation of such program. Sub-Adviser is responsible for compliance with the provisions of Section 817(h) of the Internal Revenue Code of 1986, as amended, applicable to the Funds.  Sub-Adviser is authorized on behalf of the Funds to enter into agreements and execute any documents required to make investments pursuant to the Prospectus, as such Prospectus may be amended from time to time.  Sub-Adviser is authorized on behalf of the Funds to:  (i)  deliver or accept delivery of, upon receipt of payment or payment upon receipt of, securities, commodities or other

property underlying any futures or options contracts, and other property purchased or sold in the Funds; (ii) enter into agreements and execute any documents (e.g., any derivatives documentation such as exchange traded and over-the-counter, as applicable) required to make investments pursuant to the Prospectus which shall include any market and/or industry standard documentation and the standard representations contained therein; and (iii) acknowledge the receipt of brokers’ risk disclosure statements, electronic trading disclosure statements and similar disclosures.

      a)   The Sub-Adviser further agrees that it:

i) will use the same skill and care in providing such services as it uses in providing services to fiduciary accounts for which it has investment responsibilities;

ii) will conform with all applicable Rules and Regulations of the Securities and Exchange Commission in all material respects and in addition will conduct its activities under this Agreement in accordance with any applicable regulations of any governmental authority pertaining to its investment advisory activities;

iii) will comply with all controlling foreign laws, regulations, and regulatory requirements as set forth by foreign regulatory agencies, as applicable;

iv) will place orders pursuant to its investment determinations for the Funds either directly with the issuer or with any broker or dealer, including an affiliated broker-dealer which is a member of a national securities exchange as permitted in accordance with guidelines established by the Board of Trustees. In placing orders with brokers and dealers, the Sub-Adviser will attempt to obtain the best combination of prompt execution of orders in an effective manner and at the most favorable price. Consistent with this obligation, when the execution and price offered by two or more brokers or dealers are comparable Sub-Adviser may, in its discretion, purchase and sell portfolio securities to and from brokers and dealers who provide the Sub-Adviser with research advice and other services. In no instance will portfolio securities be purchased from or sold to the Adviser, Sub-Adviser or any affiliated person of either the Trust, Adviser, or Sub-Adviser, except as may be permitted under the 1940 Act;

v) will report regularly to Adviser and to the Board of Trustees and will make appropriate persons available for the purpose of reviewing with representatives of Adviser and the Board of Trustees on a regular basis at reasonable times the management of the Funds, including, without limitation, review of the general investment strategies of the Funds, the performance of the Funds in relation to standard industry indices, interest rate considerations and general conditions affecting the marketplace and will provide various other reports from time to time as reasonably requested by Adviser;

vi) will provide to the Adviser (i) a monthly compliance checklist developed for each Fund by Adviser and Sub-Adviser, (ii) quarterly reports developed for each Fund by Adviser and Sub-Adviser, and (iii) other compliance and reporting information as reasonably requested by the Adviser or the Board of Trustees from time-to-time;

All information and advice furnished by one party to the other party (including their respective agents, employees, and representatives and the agents, employees, and representatives of any affiliates) hereunder shall be treated as confidential and shall not be disclosed to third parties, except as may be necessary to comply with applicable laws, rules and regulations, subpoenas, court orders, and as required in the administration and management of the Funds.

12. Duration and Termination.  The Agreement will become effective as to a Fund upon execution or, if later, on the date that initial capital for such Fund is first provided to it and, unless sooner terminated as provided herein, will continue in effect for two years from the effective date of the initial Investment Sub-Advisory Agreement with regard to all Fund(s) covered by this Agreement. Thereafter, if not terminated as to a Fund, this Agreement will continue from year to year through June 30th of each successive year following the initial two year period, for each Fund covered by this Agreement, as listed on Schedule A, provided that such continuation is specifically approved at least annually by the Trust’s Board of Trustees or by vote of a majority of the outstanding voting securities of such Fund(s), and in either event approved also by a majority of the Trustees of the Trust who are not interested persons of the Trust, or of the Adviser, or of the Sub-Adviser.

Add the following paragraphs to the end of Section 13.  Acknowledgements of Adviser, as follows:

      e)   The assets in the Funds are free from all liens and charges, and undertakes that no liens or charges will arise from the act or omissions of Adviser or the Trust which may prevent Sub-Adviser from giving a first priority lien or charge on the assets solely in connection with Sub-Adviser’s authority to direct the deposit of margin or collateral to the extent necessary to meet the obligations of the Funds with respect to any investments made pursuant to the Prospectus; and

      f)   The Adviser will promptly notify the Sub-Adviser if any “government entity” assets, within the meaning of Rule 206(4)-5 under the Advisers Act, are contributed to the Funds.
