NOW, THEREFORE, in consideration of the mutual covenants and benefits set forth herein, the parties do hereby agree as follows:

1.Duties of the Sub-Adviser. Subject to supervision and oversight of the Adviser and the Fund's Board of Directors (the “Board”), and in accordance with the terms and conditions of the Agreement, the Sub-Adviser shall manage all of the securities and other assets of the Segregated Portfolios entrusted to it hereunder (the “Assets”), including the purchase, retention and disposition of the Assets, in accordance with the Segregated Portfolios’ respective investment objectives, guidelines, policies and restrictions (if any) as stated in the constitutional documents of the Fund and in the applicable corporate documents of each Segregated Portfolio, as currently in effect and as amended or supplemented from time to time (referred to collectively as the “Documents”), and subject to the following:

(a)The Sub-Adviser shall, subject to subparagraph (b), determine from time to time what Assets will be purchased, retained or sold by the Segregated Portfolios, and what portion of the Assets will be invested or held uninvested in cash as is permissible.

(b)In the performance of its duties and obligations under this Agreement, the Sub-Adviser shall act in conformity with the Documents, the written instructions and directions of the Adviser and of the Board, the requirements of the 1940 Act, the Advisers Act, the Commodity Exchange Act, the Internal Revenue Code of 1986, as amended (the “Code”), and all applicable laws and regulations.

(c)The Sub-Adviser shall determine the Assets to be purchased or sold by the Segregated Portfolios as provided in subparagraph (a) and will place orders with or through such persons, brokers or dealers to carry out the policy with respect to brokerage set forth in the applicable Documents or as the Board or the Adviser may direct in writing from time to time, in conformity with all applicable laws. In executing Segregated Portfolio transactions and selecting brokers or dealers, the Sub-Adviser will use its best efforts to seek on behalf of each Segregated Portfolio the best execution and overall terms available. In assessing the best overall terms available for any transaction, the Sub-Adviser shall consider all factors that it deems relevant, including the breadth of the market in the security, the price of the security, the financial condition and execution capability of the broker or dealer, and the reasonableness of the commission, if any, both for the specific transaction and on a continuing basis. In evaluating the best overall terms available, and in selecting the broker-dealer to execute a particular transaction, the Sub-Adviser may also consider the brokerage and research services provided (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Consistent with any guidelines established by the Board and Section 28(e) of the Exchange Act, the Sub-Adviser is authorized to pay to a broker or dealer who provides such brokerage and research services a commission for executing a portfolio transaction for a Segregated Portfolio which is in excess of the amount of commission another broker or dealer would have charged for effecting that transaction if, but only if, the Sub-Adviser determines in good faith that such commission was reasonable in relation to the value of the brokerage and research services provided by such broker or dealer viewed in terms of that particular transaction or in terms of the overall responsibilities of the Sub-Adviser to its discretionary clients, including the

Segregated Portfolio. In addition, the Sub-Adviser is authorized to allocate purchase and sale orders for securities to brokers or dealers (including brokers and dealers that are affiliated with the Adviser, Sub-Adviser or the Trust’s principal underwriter) if the Sub-Adviser believes that the quality of the transaction and the commission are comparable to what they would be with other qualified firms. In no instance, however, will the Assets be purchased from or sold to the Adviser, Sub-Adviser, the Trust’s principal underwriter, or any affiliated person of the Trust, Adviser, the Sub-Adviser or the principal underwriter, acting as principal in the transaction, except to the extent permitted by the U.S. Securities and Exchange Commission (“SEC”) and the 1940 Act and applicable law.

(d)The Sub-Adviser shall maintain all books and records with respect to transactions involving the Assets required by subparagraphs (b)(1), (5), (6), (7), (8), (9) and (10) and paragraph (f) of Rule 31a-1 under the 1940 Act. The Sub-Adviser shall keep the books and records relating to the Assets required to be maintained by the Sub-Adviser under this Agreement and shall timely furnish to the Adviser all information relating to the Sub-Adviser’s services under this Agreement needed by the Adviser to keep the other books and records of the Segregated Portfolio required by Rule 31a-1 under the 1940 Act, as requested by the Adviser. The Sub-Adviser agrees that all records that it maintains on behalf of a Segregated Portfolio are property of the Segregated Portfolio and the Sub-Adviser will surrender promptly to the Segregated Portfolio any of such records upon the Segregated Portfolio’s request; provided, however, that the Sub-Adviser may retain a copy of such records. In addition, for the duration of this Agreement, the Sub-Adviser shall preserve for the periods prescribed by Rule 31a-2 under the 1940 Act any such records as are required to be maintained by it pursuant to this Agreement, and shall transfer said records to any successor sub-adviser upon the termination of this Agreement (or, if there is no successor sub-adviser, to the Adviser).

(e)The Sub-Adviser shall provide the Segregated Portfolio’s custodian (if any) on each business day with information relating to all transactions concerning the Assets and shall provide the Adviser with such information upon request of the Adviser and shall otherwise cooperate with and provide reasonable assistance to the Adviser, the Fund’s administrator, the Fund’s custodian and foreign custodians (if any), the Fund’s transfer agent and pricing agents (if any) and all other agents and representatives of the Fund.

(f)The Adviser acknowledges that the Sub-Adviser performs investment advisory services for various other clients in addition to the Segregated Portfolios and, to the extent it is consistent with applicable law and the Sub-Adviser’s fiduciary obligations, the Sub-Adviser may give advice and take action with respect to any of those other clients that may differ from the advice given or the timing or nature of action taken for a particular Segregated Portfolio.

(g)The Sub-Adviser shall promptly notify the Adviser of any financial condition that is reasonably and foreseeably likely to impair the Sub-Adviser’s ability to fulfill its commitment under this Agreement.

(h)The Sub-Adviser shall, unless and until otherwise directed by the Adviser or the Board and consistent with the best interests of each Segregated Portfolio, be responsible for exercising (or not exercising in its discretion) all rights of security holders with respect to securities held by each Segregated Portfolio, including but not limited to: reviewing proxy solicitation materials, voting and handling proxies and converting, tendering exchanging or redeeming securities. The Sub-Adviser will have no obligation to advise, initiate or take any other action on behalf of the Adviser, the Segregated Portfolios or the

Assets in any legal proceedings (including, without limitation, class actions and bankruptcies) relating to the securities comprising the Assets or any other matter. Sub-Adviser will not file proofs of claims relating to the securities comprising the Assets or any other matter and will not notify the Adviser, the Segregated Portfolios or the Trust’s custodian of class action settlements or bankruptcies relating to the Assets.

(i)In performance of its duties and obligations under this Agreement, the Sub-Adviser shall not consult with any other sub-adviser to the Segregated Portfolios or a sub-adviser to a portfolio that is under common control with the Segregated Portfolios concerning the Assets, except as permitted by the policies and procedures of the Segregated Portfolios. The Sub-Adviser shall not provide investment advice to any assets of the Segregated Portfolios other than the Assets which it sub-advises.

(j)On occasions when the Sub-Adviser deems the purchase or sale of a security to be in the best interest of the Segregated Portfolios as well as other clients of the Sub-Adviser, the Sub-Adviser may, to the extent permitted by applicable law and regulations, aggregate the order for securities to be sold or purchased. In such event, the Sub-Adviser will allocate securities so purchased or sold, as well as the expenses incurred in the transaction, in a manner the Sub-Adviser reasonably considers to be equitable and consistent with its fiduciary obligations to the Segregated Portfolio and to such other clients under the circumstances.

(k)The Sub-Adviser shall maintain books and records with respect to the Segregated Portfolios’ securities transactions and keep the Board and the Adviser fully informed on an ongoing basis as agreed by the Adviser and the Sub-Adviser of all material facts concerning the Sub-Adviser and its key investment personnel providing services with respect to the Segregated Portfolios and the investment and the reinvestment of the Assets of the Segregated Portfolios. The Sub-Adviser shall furnish to the Adviser or the Board such reasonably requested regular, periodic and special reports, balance sheets or financial information, and such other information with regard to its affairs as the Adviser or Board may reasonably request and the Sub-Adviser will attend meetings with the Adviser, as reasonably requested, to discuss the foregoing. Upon the request of the Adviser, the Sub-Adviser shall also furnish to the Adviser any other information relating to the Assets that is required to be filed by the Adviser with the SEC or sent to shareholders under the 1940 Act (including the rules adopted thereunder) or any exemptive or other relief that the Adviser obtains from the SEC.

(l)The fair valuation of securities in a Segregated Portfolio may be required when the Adviser becomes aware of significant events that may affect the pricing of all or a portion of a Segregated Portfolio’s portfolio. The Sub-Adviser will provide assistance in determining the fair value of the Assets, as necessary and reasonably requested by the Adviser or its agent, and use reasonable efforts to arrange for the provision of valuation information or a price(s) from a party(ies) independent of the Sub-Adviser if market prices are not readily available, it being understood that the Sub-Adviser will not be responsible for determining the value of any such security.

(m)To carry out the duties and responsibilities provided hereunder, Sub-Adviser is hereby authorized, as agent and attorney-in-fact for the Fund, on behalf of each Segregated Portfolio, to place orders and issue instructions for the Segregated Portfolio. In all purchases, sales and other transactions in securities for the Segregated Portfolio, Sub-Advisor is authorized to exercise full discretion and act for the Segregated Portfolio in the same manner and with the same force and effect as the Segregated Portfolio might or

could do with respect to such purchases, sales or other transactions, as well as with respect to all other things necessary or incidental to the furtherance or conduct of such purchases, sales or other transactions.

2.Duties of the Adviser. The Adviser (or its delegee) shall continue to have responsibility for all services to be provided to the Segregated Portfolios pursuant to the Advisory Agreement and shall oversee and review the Sub-Adviser’s performance of its duties under this Agreement; provided, however, that in connection with its management of the Assets, nothing herein shall be construed to relieve the Sub-Adviser of responsibility for compliance with the Documents, the written instructions and directions of the Board, the requirements of the 1940 Act, the Code, and all applicable laws and regulations.

Until so provided, the Sub-Adviser may continue to rely on those documents previously provided. The Adviser shall not, and shall not permit any of the Segregated Portfolios to use the Sub-Adviser’s name or make representations regarding Sub-Adviser or its affiliates without prior written consent of Sub-Adviser, such consent not to be unreasonably withheld. Notwithstanding the foregoing, the Sub-Adviser’s approval is not required when the information regarding the Sub-Adviser used by the Adviser or the Segregated Portfolio is limited to information disclosed in materials provided by the Sub-Adviser to the Adviser in writing specifically for use in the Segregated Portfolio’s registration statement, as amended or supplemented from time to time, or in Segregated Portfolio shareholder reports or proxy statements and the information is used (a) as required by applicable law, rule or regulation, in the Documents of the Segregated Portfolio or in Segregated Portfolio shareholder reports or proxy statements; or (b) as may be otherwise specifically approved in writing by the Sub-Adviser prior to use.

4.Compensation to the Sub-Adviser. For the services to be provided by the Sub-Adviser pursuant to this Agreement, the Adviser will pay the Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation therefore, a sub-advisory fee at the rate specified in Schedule A which is attached hereto and made part of this Agreement.

Except as may otherwise be prohibited by law or regulation (including any then current SEC staff interpretations), the Sub-Adviser may, in its sole discretion and from time to time, waive a portion of its fee.

Notwithstanding anything to the contrary contained herein, no party to this Agreement shall be responsible or liable for its failure to perform under this Agreement or for any losses to the Assets resulting from any event beyond the reasonable control of such party or its agents, including, but not limited to, nationalization, expropriation, devaluation, seizure or similar action by any governmental authority, de facto or de jure; or enactment, promulgation, imposition or enforcement by any such governmental authority of currency restrictions, exchange controls, levies or other charges affecting the Assets; or the breakdown, failure or malfunction of any utilities or telecommunications systems; or any order or regulation of any banking or securities industry including changes in market rules and market conditions affecting the execution or settlement of transactions; or acts or war, terrorism, insurrection or revolution; or acts of God, or any other similar event.

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 1940 Act will be resolved by reference to such term or provision of the 1940 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 1940 Act. Specifically, the terms “vote of a majority of the outstanding voting securities,” “interested persons,” “assignment,” and “affiliated persons,” as used herein will have the meanings assigned to them by Section 2(a) of the 1940 Act. In addition, where the effect of a requirement of the 1940 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 will be deemed to incorporate the effect of such rule, regulation or order.

20.Headings. The headings in the sections of this Agreement are inserted for convenience of reference only and will not constitute a part hereof.

The Fund, for and on behalf of the Segregated Portfolios, the Adviser, and the Sub-Adviser are entering into this Agreement with the express intention that any liabilities of the Fund to the Sub-Adviser under this Agreement (whether for payment of the fees and expenses or pursuant to an indemnity provision or otherwise) that relate to the provision of the Services for the benefit of a particular Segregated Portfolio are the separate and exclusive liabilities of the Fund for and on behalf of such Segregated Portfolio.

21.Miscellaneous.

(a)Where the effect of a requirement of the 1940 Act or Advisers Act reflected in any provision of this Agreement is altered by a rule, regulation or order of the SEC, whether of special or general application, such provision shall be deemed to incorporate the effect of such rule, regulation or order.

(b)The parties agree that this Agreement, and any other documents to be delivered in connection herewith, may be executed and delivered by electronic transmission (including, without limitation, by .pdf, DocuSign, or other electronic signature platform). Any such execution and delivery shall be deemed to have the same force and effect as delivery of an original manually executed copy of this Agreement. Each party agrees that it will not contest the validity or enforceability of this Agreement solely because it was executed by means of an electronic signature.

(c)The provisions of this Agreement that by their nature are intended to survive termination or expiration shall so survive, including without limitation: (i) the representations and warranties of the parties; (ii) confidentiality and data protection obligations; (iii) indemnification and limitation of liability provisions; (iv) recordkeeping and inspection rights; (v) governing law and dispute resolution; and (vi) this Survival clause.
