The Fund will invest and reinvest its assets in accordance with the investment objective(s), policies and limitations specified in the prospectus (the “Prospectus”) of the Trust relating to the Series filed with the SEC as part of the Trust’s Registration Statement on Form N-1A, as it may be periodically amended or supplemented and in accordance with exemptive orders and no-action letters issued to the Trust by the SEC and its staff.

2. Duties of the Adviser

(a) Management and Administrative Services. The Adviser shall perform, or arrange for the performance of, the management and administrative services necessary for the operation of the Fund, including administering shareholder accounts and handling shareholder relations. The Adviser shall provide the Fund with office space, facilities, equipment and necessary personnel and such other services as the Adviser, subject to review by the Fund Board, from time to time shall determine to be necessary or useful to perform its obligations under this Agreement. The Adviser, also on behalf of the Fund, shall conduct relations with custodians, depositories, transfer agents, pricing agents, dividend disbursing agents, other shareholder servicing agents, accountants, attorneys, underwriters, brokers and dealers, foreign currency dealers and futures commission merchants, corporate fiduciaries, insurers, banks and such other persons in any such other capacity deemed to be necessary or desirable.

Subject to paragraph (c) below, the Adviser is authorized, in its sole discretion, to: (i) obtain and evaluate pertinent economic, financial, and other information affecting the Fund and its investment assets as such information relates to securities, commodities or other financial instruments that are purchased for or considered for purchase by the Fund; (ii) make investment decisions for the Fund; (iii) place purchase and sale orders for portfolio transactions on behalf of the Fund and manage otherwise uninvested cash assets of the Fund; (iv) arrange for the pricing of Fund securities, commodities and other financial instruments; (v) execute account documentation, agreements, contracts and other documents as may be requested by brokers, dealers, counterparties and other persons in connection with the Adviser’s management of the assets of the Fund (in such respect, and only for this limited purpose, the Adviser will act as the Fund’s agent and attorney-in-fact); (vi) employ professional portfolio managers and analysts who provide research and other services to the Fund; and (vii) make decisions with respect to the use

- 2 -

by the Fund of borrowing for leverage or other investment purposes as consistent with the Fund’s investment objective(s) and policies. The Adviser will in general take such action as is appropriate to effectively manage the Fund’s investment practices.

In addition:

(1) The Adviser will maintain and preserve the records specified in Section 17 of this Agreement and any other records related to the Fund’s transactions as are required under any applicable state or federal securities or commodities law or regulation, including: the 1940 Act, the CEA, the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the Advisers Act.

(2) The Adviser will comply with procedures of each Board (collectively, the “Board Procedures”) provided to the Adviser. The Adviser will notify the Board as soon as reasonably practicable upon detection of any material breach of such Board Procedures with respect to the Fund.

(3) The Adviser will maintain a written code of ethics (the “Code of Ethics”) that it reasonably believes complies with the requirements of Rule 17j-1 under the 1940 Act (“Rule 17j-1”), a copy of which will be provided to the Trust, and will institute procedures reasonably necessary to prevent any “Access Person” (as defined in Rule 17j-1) from violating its Code of Ethics. The Adviser will follow such Code of Ethics in performing its services under this Agreement. Further, the Adviser represents that it has policies and procedures regarding the detection and prevention of the misuse of material, nonpublic information by the Adviser and its employees, a copy of which it will provide to the Trust upon any reasonable request. The Adviser shall ensure that its employees will comply in all material respects, to the extent applicable, with the provisions of Section 16 of the Exchange Act, and to cooperate reasonably with the Trust for purposes of filing any required reports with the SEC, CFTC or such other regulator having appropriate jurisdiction.

(4) The Adviser will manage, or cause to be managed, the investment and reinvestment of the assets of the Fund in a manner consistent with the Fund’s investment objectives and policies as stated in the Prospectus of the Series. The Adviser also will manage, or cause to be managed, the investments of the Fund in a manner consistent with any and all applicable investment restrictions (including diversification requirements, if applicable) contained in the 1940 Act, the CEA and the rules and regulations under the 1940 Act and the CEA, any exemptive orders issued by the SEC applicable to the Fund or the Trust or any SEC or CFTC staff no-action or interpretive letter applicable to the Fund or the Trust, and any applicable state securities or commodities law or regulation.

The Adviser agrees to perform its duties hereunder in complete compliance with the Trust’s policies and procedures adopted pursuant to Rule 38a-1 of the 1940 Act, and the Adviser’s duties and obligations of Rule 206(4)-7 under the Advisers Act and as a CPO under the CEA, including providing the Chief Compliance Officer of the Trust and/or the Board with such information, reports and certifications as they may reasonably request.

(c) Subadvisers. In carrying out its responsibilities hereunder, the Adviser may, in its sole discretion to the extent permitted by applicable law, any exemptive orders issued by the SEC applicable to the Fund or any SEC or CFTC staff no-action or interpretive letter applicable to the Fund, employ, retain or otherwise avail itself of the services of other persons or entities (a “Subadviser”) at the Adviser’s own cost and expense, including without limitation, affiliates of the Adviser, on such terms as the Adviser shall determine to be necessary, desirable or appropriate. Retention of one or more Subadvisers, or the employment or retention of other persons or entities to perform services, shall in no way reduce the responsibilities or obligations of the Adviser under this Agreement and the Adviser shall be responsible for all acts and omissions of such Subadvisers, or other persons or entities, in connection with the performance of the Adviser’s duties hereunder unless otherwise agreed by the parties.

3. Information and Reports

(a) The Adviser will keep the Fund Board informed of developments relating to its duties as investment adviser of which the Adviser has, or should have, knowledge that would materially affect the Fund. In this regard, the Adviser will provide the Board and the officers of the Fund and the Trust with such periodic reports concerning the obligations the Adviser has assumed under this Agreement as the Board or such officers may from time to time reasonably request. Additionally, upon the request of the Fund Board, prior to each Fund Board meeting, the Adviser will provide the Fund Board, or cause any Subadviser to provide the Fund Board, with reports regarding the management of the Fund during the most recently completed quarter, including certifications that the Fund is in compliance with its respective investment objectives and practices, the 1940 Act, the CEA and applicable rules and regulations thereunder, and the requirements of Subchapter M of the Code, if applicable, and other information in such form as may be mutually agreed upon by the Adviser and the Fund. The Adviser also will certify quarterly to the Fund Board that it and its Advisory Persons have complied materially with the requirements of Rule 17j-1

- 4 -

during the previous quarter or, if not, explain what the Adviser has done to seek to ensure such compliance in the future. Annually, the Adviser will furnish a written report, which complies with the requirements of Rule 17j-1 and Rule 38a-1, concerning the Adviser’s Code of Ethics and compliance program, respectively, to the Board. Upon written request of the Fund with respect to violations of the Code of Ethics directly affecting the Fund, the Adviser will permit representatives of the Board to examine reports (or summaries of the reports) required to be made by Rule 17j-1(d)(1) relating to enforcement of the Code of Ethics.

(b) The Adviser will provide the Board with any information reasonably requested regarding its management of the Fund required for any shareholder report, amended registration statement, or prospectus supplement to be filed by the Fund or the Trust with appropriate regulators. The Adviser will promptly inform the Board if any information in the Prospectus or Statement of Additional Information (as amended from time to time) (“SAI”) of the Trust, with respect to the Series, to the Adviser’s knowledge is (or will become) inaccurate or incomplete.

4. Standard of Care

The Adviser will exercise its best judgment and will act in good faith and use reasonable care and in a manner consistent with applicable federal and state laws and regulations in rendering the services it agrees to provide under this Agreement.

5. Adviser’s Duties Regarding Fund Transactions

(a) Placement of Orders. The Adviser will take, or cause to be taken, all actions that it considers necessary to implement the investment policies of the Fund, and, in particular, to place all orders for the purchase or sale of securities, commodities or other investments for the Fund with brokers, dealers or other persons that the Adviser, in its sole discretion, selects. To that end, the Adviser is authorized as the Fund’s agent to give instructions to the Fund’s custodian as to deliveries of securities, commodities or other investments and payments of cash for the Fund’s account. In connection with the selection of brokers or dealers and the placement of purchase and sale orders, the Adviser is subject to the supervision of the Board and is directed at all times to seek to obtain best execution and price within the policy guidelines determined by the Board and set out in the current Prospectus or SAI of the Trust in respect of the Series, subject to provisions (b), (c) and (d) of this Section 5.

(b) Selection of Brokers and Dealers. To the extent permitted by the policy guidelines set out in the current Prospectus or SAI of the Trust in respect of the Series, in connection with the selection of brokers and dealers to execute portfolio transactions, the Adviser is authorized to consider not only the available prices and rates of brokerage commissions, but also other relevant factors, which may include, without limitation: the execution capabilities of the brokers and dealers; the research, custody,

- 5 -

and other services provided by the brokers and dealers that the Adviser believes will enhance its general portfolio management capabilities; the size of the transaction; the difficulty of execution; the operational facilities of these brokers and dealers; the risk to a broker or dealer of positioning a block of securities; and the overall quality of brokerage and research services provided by the brokers and dealers. In connection with the foregoing, the Adviser is specifically authorized to pay those brokers and dealers who provide brokerage and research services to the Adviser a higher commission than that charged by other brokers and dealers if the Adviser determines in good faith that the amount of the commission is reasonable in relation to the value of the services in terms of either the particular transaction or in terms of the Adviser’s overall responsibilities with respect to the Fund and to any other client accounts or portfolios that the Adviser advises. The execution of such transactions will not be considered to represent an unlawful breach of any duty created by this Agreement or otherwise.

(c) Soft Dollar Arrangements. On an ongoing basis, but not less often than annually, the Adviser will identify and provide a written description to the Board of all “soft dollar” arrangements that the Adviser maintains with respect to the Fund or with brokers or dealers that execute transactions for the Fund, if any, and of all research and other services provided to the Adviser by a broker or dealer (whether prepared by such broker or dealer or by a third party), if any, as a result, in whole or in part, of the direction of Fund transactions to the broker or dealer.

(d) Aggregated Transactions. On occasions when the Adviser deems the purchase or sale of a security, commodity or other financial instrument to be in the best interest of the Fund, as well as other clients, the Adviser is authorized, but not required, to aggregate purchase and sale orders for securities, commodities or other financial instruments held (or to be held) by the Fund with similar orders being made on the same day for other client accounts or portfolios that the Adviser manages. When an order is so aggregated, the Adviser may allocate the recommendations or transactions among all accounts and portfolios for whom the recommendation is made or transaction is effected on a basis that the Adviser reasonably considers equitable and consistent with its fiduciary obligations to the Fund and its other clients. The Adviser and the Fund recognize that in some cases this procedure may adversely affect the size of the position obtainable for the Fund.

6. Compensation

The Adviser will not receive any compensation for services rendered by the Adviser as investment adviser to the Fund, and is not entitled to any compensation under this Agreement.

- 6 -

7. Expenses

(a) The Adviser. Except as otherwise provided in Section 7(b) of this Agreement, the Adviser agrees to pay all expenses incurred by the Fund.

(b) The Fund. The Fund agrees to pay all of the following expenses incurred by the Fund: (i) interest and taxes (including, but not limited to, income, excise, transfer and withholding taxes); (ii) expenses of the Fund incurred with respect to the acquisition and disposition of portfolio securities, commodities or other financial instruments and the execution of portfolio transactions, including brokerage commissions; (iii) expenses incurred in connection with any distribution plan adopted by the Fund, including distribution fees; (iv) litigation expenses; and (v) any extraordinary expenses (which, for the avoidance of doubt, do not include expenses related to the organization of the Fund or the ongoing corporate expenses of maintaining the Fund).

8. Services to Other Companies or Accounts

The Fund understands that the Adviser and its affiliates now act, will continue to act and may act in the future as investment manager or adviser to fiduciary and other managed accounts, and as an investment manager or adviser to other investment companies or commodity pools, including any offshore entities or private accounts. The Fund has no objection to the Adviser and its affiliates so acting. The Fund recognizes that in some cases this procedure may adversely affect the size of the position obtainable for the Fund and understand that the persons employed by the Adviser to assist in the performance of the Adviser’s duties under this Agreement may not devote their full time to such service, and that nothing contained in this Agreement will be deemed to limit or restrict the right of the Adviser to engage in and devote time and attention to other businesses or to render services of whatever kind or nature. This Agreement will not in any way limit or restrict the Adviser or any of its directors, officers, employees, or agents from buying, selling or trading any securities, commodities or other investment instruments for its or their own account or for the account of others for whom it or they may be acting, provided that such activities will not adversely affect or otherwise impair the performance by the Adviser of its duties and obligations under this Agreement and such activities are not otherwise prohibited by applicable law.

9. Affiliated Brokers

The Adviser or any of its affiliates may act as broker or agent in connection with the purchase or sale of securities, commodities or other investments for the Fund, subject to: (i) the requirement that the Adviser seek to obtain best execution and price within the policy guidelines determined by the Trust Board and set out in the current Prospectus or SAI of the Trust with respect to the Series; (ii) the provisions of the 1940 Act, the CEA and the Advisers Act; (iii) the provisions of the Exchange Act, including, but not limited to, Section 11(a) thereof; and (iv) other provisions of applicable law. These brokerage services are not within the scope of the

- 7 -

duties of the Adviser under this Agreement. Subject to the requirements of applicable law and any procedures adopted by the Board, the Adviser or its affiliates may receive brokerage commissions, fees or other remuneration from the Fund for these services.

10. Custody
