APPOINTMENT OF THE SUB-ADVISER

The Investment Adviser hereby appoints the Sub-Adviser to act as an investment adviser for each Fund listed on Appendix A, as amended from time to time, subject to the supervision and oversight of the Investment Adviser and the Trustees of the Trust, and in accordance with the terms and conditions of this Agreement. The Sub-Adviser will be an independent contractor and will have no authority to act for or represent the Trust or the Investment Adviser in any way or otherwise be deemed an agent of the Trust or the Investment Adviser except as expressly authorized in this Agreement or another writing by the Trust, the Investment Adviser and the Sub-Adviser.

For so long as Sub-Adviser acts as investment sub-adviser for a Fund under this Agreement, the Investment Adviser or its affiliate shall grant to Sub-Adviser a no-fee license to use such Fund's underlying index, if any, in connection with the performance of its obligations hereunder and pursuant to the terms of an Index License Agreement as deemed necessary or appropriate between the parties.

ACCEPTANCE OF APPOINTMENT

The Sub-Adviser accepts that appointment for the Funds and agrees to render the services herein set forth, for the compensation herein provided.

The assets of each Fund will be maintained in the custody of a custodian (who shall be identified by the Investment Adviser in writing). If the Sub-Adviser is responsible for only a portion of a Fund’s assets, the Investment Adviser will specify on Appendix A or otherwise designate to the Sub-Adviser in writing the portion of the assets for which the Sub-Adviser is responsible, and, unless the context otherwise requires, any reference to a “Fund” in this Agreement shall be deemed to refer only to such designated portion of the Fund’s assets. The Sub-Adviser will not have custody of any securities, cash or other assets of the Fund and will not be liable for any loss resulting from any act or omission of the custodian other than acts or omissions arising in reasonable reliance on instructions of the Sub-Adviser.

SERVICES TO BE RENDERED BY THE SUB-ADVISER TO THE TRUST

A. As adviser to each Fund, the Sub-Adviser will coordinate the investment and reinvestment of the assets of the Fund and determine the composition of the assets of the Fund, in accordance with the terms of this Agreement, each Fund’s Prospectus and Statement of Additional Information and subject to the direction, supervision and control of the Investment Adviser and the Trustees of the Trust.

B. As part of the services it will provide hereunder, the Sub-Adviser will:

(i) formulate and implement a continuous investment program and portfolio management compliance and reporting program for each Fund;

(ii) take whatever steps it deems necessary or advisable to implement the investment program for each Fund by arranging for the purchase and sale of securities and other investments;

(iii) keep the Trustees of the Trust and the Investment Adviser fully informed on an ongoing basis of all material facts concerning the investment and reinvestment of the assets of each Fund and the operations of the Sub-Adviser relating thereto, make regular and periodic special written reports of such additional information concerning the same as may reasonably be requested from time to time by the Investment Adviser or the Trustees of the Trust, and attend meetings with the Investment Adviser and/or the Trustees, as reasonably requested, to discuss the foregoing;

(iv) if requested by the Investment Adviser, provide advice about the fair value of the securities and other investments/assets in the Fund; provided, however, that the parties acknowledge that the Trust is responsible for any fair value pricing; and

(v) cooperate with and provide reasonable assistance to the Investment Adviser, the Trust’s administrator, the Trust’s custodian and foreign custodians, the Trust’s transfer agent and pricing agents and all other agents and representatives of the Trust and the Investment Adviser, keep all such persons fully informed as to such matters as the Sub-Adviser considers in good faith to be necessary to the performance of their obligations to the Trust and the Investment Adviser, provide prompt responses to reasonable requests made by such persons and maintain any appropriate interfaces with each so as to promote the efficient exchange of information.

C. In furnishing services hereunder, the Sub-Adviser shall be subject to, and shall perform in accordance with the following: (i) the then effective Prospectus and Statement of Additional Information of the Trust filed with the Securities and Exchange Commission (“SEC”) and delivered to the Sub-Adviser, as the same may be thereafter modified, amended and/or supplemented (“Prospectus and SAI”); (ii) the Investment Company Act, the Advisers Act, the Commodity Exchange Act (“CEA”) and the rules of the National Futures Association (“NFA”), and all other federal and state laws or regulations applicable to the Sub-Adviser’s performance of its obligations herein; and (iii) any order or no-action letter of the SEC, the Commodity Futures Trading Commission (“CFTC”) or NFA governing the operation of the Trust or a Fund. Prior to the commencement of the Sub-Adviser’s services hereunder, the Investment Adviser shall provide the Sub-Adviser with current copies of the Prospectus and SAI, any order or no-action letter of the SEC, CFTC or NFA governing the operation of the Trust or a Fund, and any relevant compliance and other policies and procedures that are adopted by the Board of Trustees and agreed upon with the Sub-Adviser. The Investment Adviser undertakes to provide the Sub-Adviser with copies or other written notice of any amendments, modifications or supplements to any such above-mentioned documents and, except as may be required by the Advisers Act or other applicable law or regulation, Sub-Adviser will not need to comply until a copy has been provided to the Sub-Adviser and agreed upon.

D. The Sub-Adviser, at its expense, will furnish: (i) all necessary facilities and personnel, including salaries, expenses and fees of any personnel required for them to faithfully perform their duties under this Agreement; and (ii) administrative facilities, including maintaining records, and all equipment necessary for the efficient conduct of the Sub-Adviser’s duties under this Agreement.

E. The Sub-Adviser will select brokers and dealers to effect all Fund transactions subject to the conditions set forth herein. Notwithstanding the foregoing, and subject to applicable federal and state laws and regulations, the Investment Adviser may direct the Sub-Adviser to use a particular broker, dealer, prime broker, futures commission merchant or collateral manager. The Sub-Adviser will place all necessary orders with brokers, dealers, or issuers, and will negotiate brokerage commissions, if applicable. The Sub-Adviser is directed at all times to seek to execute transactions for each Fund in accordance with applicable federal and state laws and regulations. In placing any orders for the purchase or sale of investments for each Fund, in the name of the Fund or its nominees, the Sub-Adviser shall seek to obtain for the Fund “best execution,” considering all of the circumstances, and shall maintain records adequate to demonstrate compliance with this requirement. In no instance will Fund securities be purchased from or sold to the Sub-Adviser, or any affiliated person thereof, except in accordance with the Investment Company Act, the Advisers Act and the rules under each, and all other federal and state laws and regulations applicable to the Trust and the Fund(s).

F. The Sub-Adviser is not authorized to engage in “soft-dollar” transactions on behalf of the Funds, except that the Sub-Adviser may engage in transactions permitted by Section 28(e) of the Securities Exchange Act of 1934, as amended (“Exchange Act”), only with the express written approval of the Investment Adviser or the Trust’s Board of Trustees.

G. On occasions when the Sub-Adviser deems the purchase or sale of a security to be in the best interest of the Fund(s) as well as other clients of the Sub-Adviser, the Sub-Adviser to the extent permitted by applicable laws and regulations, may, but shall be under no obligation to, aggregate the securities to be purchased or sold to attempt to obtain a fair and reasonable result and efficient execution, provided that the Sub-Adviser does not favor any account over any other account. Allocation of the securities so purchased or sold, as well as the expenses incurred in the transaction, will be made by the Sub-Adviser in the manner which the Sub-Adviser considers to be the most equitable and consistent with its fiduciary obligations to each Fund and to its other clients over time. The Investment Adviser agrees that the Sub-Adviser and its affiliates may give advice and take action in the performance of their duties with respect to any of their other clients that may differ from advice given, or the timing or nature of actions taken, with respect to the Fund. The Investment Adviser also acknowledges that the Sub-Adviser and its affiliates are fiduciaries to other entities, some of which have the same or similar investment objectives (and will hold the same or similar investments) as the Fund, and that the Sub-Adviser will carry out its duties hereunder together with its duties under such relationships.

H. The Sub-Adviser will provide the Investment Adviser with copies of the Sub-Adviser’s current policies and procedures adopted in accordance with Rule 206( 4)-7 under the Adviser Act. To the extent the Funds are required by the Investment Company Act to adopt any such policy or procedure, the Investment Adviser will submit such policy or procedure to the Trust’s Board of Trustees for adoption by each of the Funds, with such modifications or additions thereto as the Board of Trustees or Investment Adviser may recommend with the concurrence of the Sub-Adviser. The Sub-Adviser shall furnish the services hereunder to the Fund in accordance with this Section 3 and such policies and procedures.

I. The Sub-Adviser will maintain all accounts, books and records with respect to each Fund as are required of an investment adviser of a registered investment company or a commodity trading advisor (“CTA”) pursuant to the Investment Company Act and Advisers Act, the CEA, and the rules thereunder, including any applicable NFA rules, and shall file with the SEC any report on Form 13F or Schedule 13G and any amendments thereto, required by the Exchange Act, with respect to its duties as are set forth herein.

The Sub-Adviser will, unless and until otherwise directed by the Investment Adviser or the Board of Trustees, exercise all rights of security holders with respect to securities held by each Fund, including, but not limited to: voting proxies in accordance with the Sub-Adviser’s then-current proxy voting policies (provided such policies have been approved by the Trust’s Board of Trustees), converting, tendering, exchanging or redeeming securities; provided, however, the Sub-Adviser is not responsible for notifying Investment Adviser of, or filing proofs of claims relating to, class action settlements or bankruptcies regarding securities or instruments held by, or other matters related to, any Fund.

COMPENSATION OF SUB-ADVISER

Investment Adviser will pay Sub-Adviser as compensation for providing services in accordance with this Agreement those fees as set forth in Appendix B-1. Investment Adviser and Sub-Adviser agree that all fees shall become due and owing to Sub-Adviser promptly after the termination date of Sub-Adviser with respect to any Fund and that the amount of such fees shall be calculated by treating the termination date as the next fee computation date. The annual base fee will be prorated for such fees owed through the termination date. In addition, the Investment Adviser shall reimburse the Sub-Adviser for actual expenses incurred by the Sub-Adviser with respect to proxy voting execution, advice and reporting.

Notwithstanding the foregoing, the parties acknowledge and agree that normal day-to-day operational communications between the parties may be sent via e-mail or File Transfer Protocol to personnel at the parties normally receiving communications of such type (or specifically requested by a party to receive such communications). However, it is specifically agreed by the parties that all notices required or permitted to be given under the following provisions of this Agreement shall be given as set forth in the first paragraph of this Section 18: Sections 3.C, 5, 6.C, 0.X, 0.X, 0.X, 00.X, 00.X and 23. Investment Adviser acknowledges and agrees that notice and delivery of any document or communication required pursuant to applicable law may be given by Sub-Adviser by electronic means, including, without limitation, posting electronically on Sub-Adviser’s website (xxxx://xxx.xxxxxx.xxx) on the Investment Adviser’s homepage.

19.

SEVERABILITY AND SURVIVAL

Should any portion of this Agreement for any reason be held to be void in law or in equity, the Agreement shall be construed, insofar as is possible, as if such portion had never been contained herein. Sections 5, 11 and 20 shall survive the termination of this Agreement.

20.

TRUST AND SHAREHOLDER LIABILITY

The Sub-Adviser is hereby expressly put on notice of the limitation of shareholder liability as set forth in the Trust Declaration and agrees that obligations, if any, assumed by the Trust pursuant to this Agreement shall be limited in all cases to the Trust and its assets, and if the liability relates to one or more series, the obligations hereunder shall be limited to the respective assets of the Fund. The Sub-Adviser further agrees that it shall not seek satisfaction of any such obligation from the shareholders or any individual shareholder of the Fund(s), nor from the Trustees or any individual Trustee of the Trust.

21.

GOVERNING LAW

The provisions of this Agreement shall be construed and interpreted in accordance with the laws of the State of New York, or any of the applicable provisions of the Investment Company Act. To the extent that the laws of the State of New York, or any of the provisions in this Agreement, conflict with applicable provisions of the Investment Company Act, the latter shall control.

22.

INTERPRETATION

Any question of interpretation of any term or provision of this Agreement having a counterpart in or otherwise derived from a term or provision of the Investment Company Act shall be resolved by reference to such term or provision of the Investment Company Act and to interpretations thereof, if any, by the United States courts or, in the absence of any controlling decision of any such court, by rules, regulations or orders of the SEC validly issued pursuant to the Investment Company Act. Specifically, the terms “vote of a majority of the outstanding voting securities,” “interested persons,” “assignment,” and “affiliated persons,” as used herein shall have the meanings assigned to them by Section 2(a) of the Investment Company Act. In addition, where the effect of a requirement of the Investment Company Act reflected in any provision of this Agreement is relaxed by a rule, regulation or order of the SEC, whether of special or of general application, such provision shall be deemed to incorporate the effect of such rule, regulation or order.

23.

CONFIDENTIALITY

Each party shall treat as confidential all Confidential Information of the other (as that term is defined below) and use such information only in furtherance of the purposes of this Agreement. Each Party shall limit access to the Confidential Information to its Affiliates, employees, consultants, auditors and regulators who reasonably require access to such Confidential Information, and otherwise maintain policies and procedures designed to prevent disclosure of the Confidential Information. For purposes of this Agreement, Confidential Information shall include all non-public business and financial information, methods, plans, techniques, processes, documents and trade secrets of a Party. Confidential Information shall not include anything that (i) is or lawfully becomes in the public domain, other than as a result of a breach of an obligation hereunder; (ii) is furnished to a Party by a third party having a lawful right to do so; or (iii) was known to the receiving Party at the time of the disclosure. Each Party shall give prompt notice to the other of any requests or demands for any Confidential Information made under lawful process by any third parties, prior to disclosure or furnishing of such Confidential Information, except to the extent such disclosure is required under law or requested by any regulator or governmental authority. Each Party agrees to reasonably cooperate with the other, at the other’s expense, in seeking reasonable protective arrangements to prevent, limit or restrict the disclosure of Confidential Information pursuant to such lawful process. This Agreement shall not be deemed to be Confidential Information.

24.

AUTHORITY TO EXECUTE TRANSACTION DOCUMENTS

Subject to any other written instructions of the Investment Adviser or the Trust, the Sub-Adviser is hereby appointed agent and attorney-in-fact for the limited purposes of executing on behalf of any Fund: account documentation, transaction term sheets and confirmations, certifications regarding the Fund’s status as an accredited investor, qualified institutional buyer, qualified purchaser, qualified eligible person or eligible contract participant and certifications regarding other factual matters as may be requested by brokers, dealers or counter parties in connection with its management of the Fund’s assets. However, nothing in this Section 24 shall be construed as imposing a duty on the Sub-Adviser to act in its capacity as attorney-in-fact for the Fund. Any person dealing with the Sub-Adviser in its capacity as attorney-in-fact hereunder for the Fund is hereby expressly put on notice that the Sub-Adviser is acting solely in the capacity as an agent of the Fund and that any such person must look solely to the Fund for enforcement of any claim against Fund, as the Sub-Adviser assumes no personal liability to such person whatsoever for obligations of the Fund entered into by the Sub-Adviser in its capacity as attorney-in-fact for the Fund.

25.
