The Advisor shall provide the Sub-Advisor with such assistance as may be reasonably requested by the Sub-Advisor in connection with its activities under this Agreement, including, without limitation, information concerning the Fund and the Fund’s affairs.

The Advisor hereby authorizes the Sub-Advisor, at all times in accordance with the Prospectus and the Guidelines, with respect to the Allocated Portion to (i) enter into, on behalf of the Fund and as its Sub-Advisor and/or agent in fact, (A) any agreement, and any supporting documentation, with any futures commission merchant registered with the U.S. Commodity Futures Trading Commission (“CFTC”) to provide execution and clearing services for exchange-traded commodity futures contracts, options on futures contracts and cleared swaps for the Fund and (B) futures (including security futures) contracts, forward foreign currency exchange contracts, options on securities (listed and over-the-counter), options on indices (listed and over-the-counter), options on foreign currency and other foreign currency transactions, swap transactions (cleared or un-cleared) (including, without limitation, interest rate, credit default, total return, and related types of swap and notional rate agreements), options on swap transactions, forward rate agreements, TBA transactions and other transactions involving the forward purchase or sale of securities, repurchase and reverse repurchase transactions, buy/sell back transactions and other similar types of investment contracts or transactions, and any agreements, instruments or documentation governing any of the foregoing (including, without limitation, brokerage agreements, execution agreements, ISDA master agreements, master securities forward transactions agreements, master repurchase agreements, master securities lending agreements, security or collateral agreements, control agreements and any other agreements, instruments or documents similar or incidental to the foregoing that currently are, or in the future become, customary or necessary with respect to the documentation of any of the foregoing, and any schedules and annexes to the aforementioned agreements, instruments and documents, and any releases, consents, waivers, amendments, elections or confirmations to any of the aforementioned agreements, instruments and documents (collectively, “Investment Instruments”), (ii) pledge and deliver cash, securities, commodities or other assets of the Fund as collateral security in connection with any Investment Instrument, and (iii) otherwise act on behalf of the Fund in connection with the exercise of any rights or the satisfaction of any obligations and liabilities of the Fund under any Investment Instruments or other agreement or documentation.

Allocations to be set by Advisor. The Advisor shall oversee the allocation of the Fund’s assets across the various investment strategies permitted under the Fund’s Prospectus. The Sub-Advisor shall manage the portfolio securities in a manner consistent with target investment strategy weightings indicated by the Advisor.

Compliance with Applicable Laws and Governing Documents. In the performance of its duties and obligations under this Agreement or otherwise, the Sub-Advisor shall act in conformity with the Fund’s Declaration of Trust (as it may be amended or modified from time to time), By-Laws (as they may be amended or modified from time to time), procedures and policies (“Policies”) adopted by the Board and/or by the Advisor, the Guidelines, and the Prospectus and with instructions and directions received in writing from the Advisor or the Board and will conform to and comply with the requirements of the 1940 Act, the Advisers Act and, to the extent applicable, the Commodity Exchange Act, as amended (“CEA”), and the rules and regulations adopted under the 1940 Act, the Advisers Act and, to the extent applicable, the CEA, from time to time, the Internal Revenue Code of 1986, as amended (the “Code”), and all applicable federal and state laws and regulations necessary to allow the Fund to qualify as a “regulated investment company” as defined in Subchapter M of the Code. The Sub-Advisor shall maintain compliance procedures and processes that are reasonably designed to ensure compliance with all laws, rules, regulations and requirements applicable to the investment advisor of a closed-end investment company like the Fund under the Advisers Act, including Rule 206(4)-7 thereunder, and the 1940 Act. No supervisory activity undertaken by the Advisor shall limit the Sub-Advisor’s full responsibility for all of its obligations and responsibilities hereunder. To the extent that the CEA and the CFTC regulations require: (A) registration by the Sub-Advisor as a commodity pool operator or commodity trading advisor and/or membership with the National Futures Association (“NFA”) with respect to the Fund, (B) specific disclosure, as applicable to the investors in the Fund, or (C) filing of reports and other documents with respect to the Fund, Sub-Advisor shall promptly and fully comply, or work with the Advisor to take reasonable steps to cause the Fund to comply, with all such requirements.

The Advisor shall provide the Sub-Advisor with copies of the Fund’s Declaration of Trust, By-Laws, Policies, the Guidelines, and the Prospectus, and shall provide the Sub-Advisor with reasonable notice of any change in the Fund’s investment objectives, policies and restrictions as stated in the Prospectus or in any Policies or Guidelines adopted by the Board and/or the Advisor, and the Sub-Advisor shall, in the performance of its duties and obligations under this Agreement, manage the Fund’s portfolio in compliance with such documents and changes, provided that the Sub-Advisor has received notice of the effectiveness of such changes from the Fund or the Advisor and any such changes to the investment objectives, policies, restrictions or guidelines for the Fund shall be reasonably acceptable to the Sub-Advisor, provided, further, that any such changes shall be deemed to be acceptable to the Sub-Advisor unless the Sub-Advisor has provided the Advisor written notice within seven (7) business days of receiving such documents that any of the changes are not reasonably acceptable. In addition to such notice, the Advisor shall provide to the Sub-Advisor a copy of a modified Prospectus reflecting such changes.

The Sub-Advisor shall not delegate investment advisory services to any third-party concerning transactions for the Fund without the prior written consent of the Advisor or the Board.

Voting of Proxies. Absent specific written instructions to the contrary provided to the Sub-Advisor by the Advisor, the Sub-Advisor shall vote, either in person or by proxy, all securities in which the Fund may be invested from time to time with respect to the Allocated Portion in accordance with its proxy voting procedures and provide a record of votes cast containing all of the voting information required by Form N-PX in an electronic format to enable the Fund to file Form N-PX as required. The Sub-Advisor shall provide its proxy voting policy (“Proxy Policy”) to the Board and the Advisor, and, if requested by the Advisor, shall provide a summary of the Proxy Policy suitable for including in the Prospectus. The Sub-Advisor shall provide the Board and the Advisor with any material amendment to the Proxy Policy within a reasonable time after such amendment has taken effect. The Sub-Advisor shall promptly inform the Advisor of all tender offers, rights offerings and other voluntary corporate action requests affecting securities in the Fund with respect to the Allocated Portion and, absent specific written instructions to the contrary provided to the Sub-Advisor by the Advisor, shall respond on behalf of the Fund to all such corporate action requests and shall complete and file notices of claims in connection with class action lawsuits concerning securities in the Fund with respect to the Allocated Portion.

Brokerage. With respect to the Allocated Portion, the Sub-Advisor is authorized, subject to the supervision and oversight of the Advisor and the Board, to establish and maintain accounts on behalf of the Fund with, and place orders for the purchase and sale of the Fund’s portfolio securities or other investments with or through, such persons, brokers or dealers, futures commission merchants or other counterparties (“brokers”) as the Sub-Advisor may elect and negotiate commissions to be paid on such transactions; provided, however, that a broker affiliated with the Sub-Advisor shall be used only in transactions permissible under applicable laws, rules and regulations, including, without limitation, the 1940 Act and the Advisers Act and the rules and regulations promulgated thereunder, as well as permitted by the Policies adopted by the Fund. The Sub-Advisor, upon reasonable request of the Advisor, shall promptly provide the Advisor with copies of all agreements regarding brokerage arrangements related to the Fund.

The Sub-Advisor shall enter into transactions and place orders for the purchase and sale of portfolio investments for the Fund’s account with brokers, dealers and/or other counterparties selected by the Sub-Advisor with respect to the Allocated Portion. In the selection of such brokers, dealers and/or other counterparties and the entering into of such transactions and placing of such orders, the Sub-Advisor shall seek to obtain for the Fund the most favorable price and execution available, except to the extent it may be permitted to pay higher brokerage commissions for brokerage and research services, as provided below. In using its reasonable efforts to obtain for the Fund the most favorable price and execution available, the Sub-Advisor, bearing in mind the best interests of the Fund at all times, shall consider all factors it deems relevant, including price, the size of the transaction, the breadth and nature of the market for the security, the difficulty of the execution, the amount of the commission, if any, the timing of the transaction, market prices and trends, the reputation, experience and financial stability of the broker, dealer or counterparty involved, and the quality of service rendered by the broker or dealer in other transactions. Subject to such policies as the Board may determine, or as may be mutually agreed to by the Advisor and the Sub-Advisor, the Sub-Advisor shall not be deemed to have acted unlawfully or to have breached any duty created by this Agreement or otherwise solely by reason of its having caused the Fund to pay a broker or dealer that provides brokerage and research services (within the meaning of Section 28(e) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), and any SEC guidance issued thereunder) to the Sub-Advisor an amount of commission for effecting an investment transaction in the Fund that is in excess of the amount of commission or spread that another broker or dealer would have charged for effecting that transaction if, but only if, the Sub-Advisor determines in good faith that such commission or spread was reasonable in relation to the value of the brokerage and research services provided by such broker or dealer viewed in terms of either that particular transaction or the overall responsibility of the Sub-Advisor with respect to the accounts for which it exercises investment discretion (as such term is defined in Section 3(a)(35) of the 1934 Act). It is recognized that the services provided by such brokers and dealers may be useful to the Sub-Advisor in connection with the Sub-Advisor’s services to other clients. The Sub-Advisor is responsible for obtaining a completed Form W-9 from any broker it selects to place orders for the Fund, and responsible for providing such to the Advisor and the Fund.

On occasions when the Sub-Advisor deems the purchase or sale of a security to be in the best interests of the Fund as well as other clients of the Sub-Advisor, the Sub-Advisor, to the extent permitted by applicable laws and regulations (including any applicable exemptive orders or SEC guidance) and subject to the trade allocation procedures approved by the Fund’s Board or the Advisor, may, but shall be under no obligation to, aggregate the securities to be sold or purchased in order to obtain the most favorable price or lower brokerage commissions or spreads and efficient execution. In such event, allocation of securities so sold or purchased, as well as the expenses incurred in the transaction, will be made by the Sub-Advisor in accordance with the approved procedures.

The Sub-Advisor shall render reports to the Advisor and/or to the Board as reasonably requested regarding commissions generated as a result of trades executed for the Fund, as well as information regarding third-party services, if any, received by the Sub-Advisor as a result of trading activity relating to the Fund with brokers and dealers.

Code of Ethics. The Sub-Advisor, including its Access Persons (as defined in subsection (e) of Rule 17j-1 under the 1940 Act), shall observe and comply with Rule 17j-1 and the Sub-Advisor’s written code of ethics, as the same may be amended from time to time (“Code of Ethics”). On at least a quarterly basis, the Sub-Advisor shall, at the request of the Advisor, either (i) certify to the Advisor that the Sub-Advisor and its Access Persons have complied in all material respects with the Sub-Advisor’s Code of Ethics or (ii) identify any (A) material violations which have occurred with respect to the Code of Ethics or (B) with respect to any Access Persons who provide services to the Fund, multiple violations (whether or not material) by the same individual(s) which have occurred with respect to the Code of Ethics. Quarterly, the Sub-Advisor shall furnish a written report, which complies with the requirements of Rule 17j-1, concerning its Code of Ethics, to the Fund and the Advisor. The Sub-Advisor shall notify the Advisor promptly of any material violation of the Code of Ethics involving employees providing services to the Fund and provide information relevant to the Fund related to any such violation. Further, the Sub-Advisor represents that it has policies and procedures regarding the detection and prevention of the misuse of material, nonpublic information by the Sub-Advisor and its employees. Upon the written request of the Advisor or Sub-Advisor, the Sub-Advisor shall permit the Advisor, its employees or agents, to examine the reports (or summaries of the reports) required to be made by the Sub-Advisor under Rule 17j-1(c)(1) and other records evidencing enforcement of the Code of Ethics.
