A. INVESTMENT ADVISORY SERVICES. Subject to the oversight of the Company’s Board of Trustees (the “Board”) and the supervision of Adviser, the Sub-Adviser shall manage the Allocated Assets in accordance with the Company’s investment objectives, policies, and restrictions as in effect from time to time and provided to the Sub-Adviser in advance, and in compliance with the requirements applicable to registered investment companies under applicable laws and those requirements applicable to regulated investment companies under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”) and such other limitations as the Adviser or the Board of Company may institute, provided that such limitations have been provided to the Sub-Adviser in advance of the effective date.

1

with respect to the Allocated Assets; (b) place purchase and sale orders for portfolio transactions for the Allocated Assets; and (c) employ professional portfolio managers and securities analysts to provide research services to the Company. In providing these services, the Sub-Adviser will conduct a continual program of investment, evaluation and, if appropriate, sale and reinvestment of the Allocated Assets. The Adviser agrees to deliver to Sub-Adviser any amendments or supplements to the Company’s Prospectus and Statement of Additional Information (the “Registration Statement”) that contain changes that pertain to the Sub-Adviser prior to the effectiveness thereof and Adviser acknowledges that Sub-Adviser reserves the right to terminate its engagement hereunder upon written notice in the event Sub-Adviser reasonably believes it can no longer manage the investments of the Allocated Assets in accordance with the Company’s investment objectives, policies and restrictions as provided therein.

B. SUB-ADVISER UNDERTAKINGS. In all matters relating to the performance of this Agreement, the Sub-Adviser shall act in conformity with the Company’s Agreement and Declaration of Trust dated July 19, 2018, as amended from time to time (the “Declaration of Trust”) and Registration Statement and with the written instructions and directions of the Board and the Adviser, provided that such written instructions and directions have been received and confirmed by the Sub-Adviser in advance of the effective date. The Sub-Adviser hereby agrees to:

(i) regularly report to the Board and the Adviser (in such form and frequency as the Adviser and Sub-Adviser mutually agree) with respect to the implementation of the investment program, compliance of the Allocated Assets with the Fund’s investment objectives, policies and restrictions, the 1940 Act and the Code, and on other topics as may reasonably be requested by the Board or the Adviser, including attendance at Board meetings, as reasonably requested, to present such reports to the Board;

(ii) upon reasonable request, consult with the Company’s pricing agent regarding the valuation of securities that are not registered for public sale, not traded on any securities markets, or otherwise may require fair valuation, provided that the Adviser acknowledges that the Sub-Adviser is not the valuation agent for the Company;

(iii) upon reasonable request, provide, subject to any obligations or undertakings reasonably necessary to maintain the confidentiality of the Sub-Adviser’s non-public information, any and all information, records and supporting documentation about the composite of accounts and the portfolios the Sub-Adviser manages that have investment objectives, policies, and strategies substantially similar to those employed by the Sub-Adviser in managing the Allocated Assets; and

(iv) upon reasonable request, review schedules of the Allocated Assets periodically provided to the Sub-Adviser by the Adviser and promptly confirm to the Adviser the concurrence of the Sub-Adviser’s records with such schedules.

D. BROKERAGE. The Sub-Adviser will select brokers and dealers to effect all orders for the purchase and sale of Allocated Assets. In selecting brokers or dealers to execute transactions on behalf of the Company, the Sub-Adviser will use its best efforts to seek the best overall terms available. In assessing the best overall terms available for any transaction, the Sub-Adviser will consider factors it deems relevant, including, without limitation, the breadth of the market in the security or commodity interest, the price of the security or commodity interest, the financial condition and execution capability of the broker or dealer and the reasonableness of the commission, if any, for the specific transaction and on a continuing basis. In selecting brokers or dealers to execute a particular transaction, and in evaluating the best overall terms available, the Sub-Adviser is authorized to consider the brokerage and research services (within the meaning of Section 28(e) of the Securities Exchange Act of 1934, as amended) provided to the Company and/or other accounts over which the Sub-Adviser exercises investment discretion, provided that the Sub-Adviser satisfies the provisions of Section 28(e) and the rules, regulations and interpretations thereunder.

E. AGGREGATION OF ORDERS. On occasions when the Sub-Adviser deems the purchase or sale of a security to be in the best interest of the Company as well as other clients of the Sub-Adviser, the Sub-Adviser may to the extent permitted by applicable laws and regulations, but shall be under no obligation to, aggregate the orders for securities to be purchased or sold. In such event, 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 the Sub-Adviser considers to be the most equitable and consistent with its fiduciary obligations to the Company and to its other clients. The Adviser recognizes that, in some cases, the Sub-Adviser’s allocation procedure may limit the size of the position that may be acquired or sold for the Company.

F. BOOKS AND RECORDS. In compliance with the requirements of Rule 31a-3 under the 1940 Act, the Sub-Adviser hereby agrees that all records which it maintains for the Company are the property of the Company and further agrees to surrender promptly to the Company copies of any of such records upon the Company’s or the Adviser’s request, provided, however, that Sub-Adviser may retain copies of any records to the extent required for it to comply with applicable laws and its internal record retention policies. The Sub-Adviser further agrees to preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the records relating to its activities hereunder required to be maintained by Rule 31a-1 under the 1940 Act and to preserve the records relating to its activities hereunder required by Rule 204-2 under the Advisers Act for the period specified in said Rule. Notwithstanding the foregoing, Sub-Adviser has no responsibility for the maintenance of the records of the Company, except for those related to the Allocated Assets.

G. SUB-ADVISER COMPLIANCE RESPONSIBILITIES. Sub-Adviser shall supply such reports or other documentation as reasonably requested from time to time by the Adviser to evidence Sub-Adviser’s compliance with the Company’s Registration Statement and any written policies or procedures adopted by the Board applicable to the Allocated Assets and any amendments or revisions thereto.

H. PROXY VOTING. The Sub-Adviser shall use its good faith judgment in a manner which it reasonably believes best serves the economic interests of the Company’s shareholders to vote or abstain from voting all proxies solicited by or with respect to the issuers of securities comprising the Allocated Assets. The Adviser shall cause to be forwarded to Sub-Adviser or its

3

designee all proxy solicitation materials that Adviser receives. Sub-Adviser agrees that it has adopted written proxy voting procedures that comply with the requirements of the Advisers Act. The Sub-Adviser further agrees that it will provide the Board, as the Board may reasonably request, with a written report of the proxies voted during the most recent 12-month period or such other period as the Board may designate, in a format reasonably acceptable to the Board. Upon reasonable request, Sub-Adviser shall provide the Adviser with all proxy voting records relating to the Allocated Assets, including but not limited to those required by Form N-PX. Upon reasonable request, Sub-Adviser will also provide an annual certification, in a form reasonably acceptable to Adviser, attesting, to the best of the Sub-Adviser’s knowledge, to the accuracy and completeness of such proxy voting records.

3. COMPENSATION OF SUB-ADVISER. The Adviser will pay the Sub-Adviser the compensation specified in Schedule A. Such fees will be computed daily and paid quarterly, calculated at the annual rate set forth in Schedule A as determined by the Company’s accounting agent. The Adviser will use its best efforts to cause the quarterly payment to be made to the Sub-Adviser approximately on or about the same date upon which the Company pays the Adviser its advisory fee, which the parties generally expect to occur within five (5) days of the end of each calendar quarter. Compensation for any partial period shall be pro-rated based on the length of the period.

4. STANDARD OF CARE. The Sub-Adviser shall exercise its best judgment in rendering its services described in this Agreement. Except as may otherwise be required by the 1940 Act or the rules thereunder or other applicable law, the Sub-Adviser shall not be liable for any error of judgment or mistake of law or for any loss suffered by the Company or the Adviser in connection with the matters to which this Agreement relates, except a loss resulting from the Sub-Adviser’s willful misfeasance, bad faith or gross negligence in the performance of its duties hereunder or from reckless disregard by it of its obligations and duties under this Agreement. The Sub-Adviser shall be solely responsible for the management of the Allocated Assets, and the Sub-Adviser’s compliance with the Advisers Act, rule and regulations thereunder, other federal and state laws, and written procedures of the Board will be determined solely by reference to the Allocated Assets. The Sub-Adviser shall have no liability with respect to the actions of any other investment adviser to the Company and shall not be charged with knowledge of the holdings or transactions of any positions of the Company other than the Allocated Assets.

5. NON-EXCLUSIVITY. The services of the Sub-Adviser to the Adviser with respect to the Allocated Assets are not to be deemed to be exclusive, and the Sub-Adviser shall be free to render investment advisory or other services to others (including other investment companies) and to engage in other activities. It is understood and agreed that the directors, officers, and employees of the Sub-Adviser are not prohibited from engaging in any other business activity or from rendering services to any other person, or from serving as partners, officers, directors, trustees, or employees of any other firm or corporation, including other investment companies. The Adviser acknowledges that Sub-Adviser may give advice and take actions in the performance of its duties to clients which differ from the advice, or the timing and nature of actions taken, with respect to other clients’ accounts (including the Allocated Assets) or employee accounts which may invest in some of the same securities recommended to advisory clients.

6. MAINTENANCE OF INSURANCE. During the term of this Agreement, the Sub-Adviser will maintain comprehensive general liability coverage and errors and omissions/director and officers coverage with limits of not less than those considered commercially reasonable and appropriate under the current industry practices. The Sub-Adviser shall promptly notify the Adviser of any reduction to or termination of said coverage.

7. CONFIDENTIALITY. Each party to this Agreement shall keep confidential any nonpublic information concerning the other party and will not use or disclose such information for any purpose other than the performance of its responsibilities and duties hereunder, unless the non-disclosing party has authorized such disclosure or if such disclosure is compelled by subpoena or is expressly required or requested by applicable federal or state regulatory authorities. In the event disclosure is required or requested as set forth above, the disclosing party will, to the extent permitted and reasonably practicable to do so under the circumstances then prevailing, provide prior written notice to the other party to allow such party an opportunity to seek an appropriate protective order or other relief, provided that such prior notice shall not be required when the disclosing party reasonably believes the request for disclosure is pursuant to a routine regulatory examination. Nonpublic information shall not include information a party to this Agreement can clearly establish was (a) known to the party prior to this Agreement; (b) rightfully acquired by the party from third parties whom the party reasonably believes are not under an obligation of confidentiality to the other party to this Agreement; (c) placed in public domain without fault of the party or its affiliates; or (d) independently developed by the party without reference or reliance upon the nonpublic information.

8. TERM OF AGREEMENT. This Agreement shall become effective as of the date hereof and shall continue in effect for an initial period of two years from the date of execution. Thereafter, this Agreement shall continue automatically for successive annual periods, provided such continuance is specifically approved at least annually by (i) the Board or (ii) a vote of a “majority” (as defined in the 0000 Xxx) of the Company’s outstanding voting securities, provided that in either event the continuance also is approved by a majority of the Board who are not “interested persons” (as defined in the 0000 Xxx) of any party to this Agreement, by vote cast in person at a meeting called for the purpose of voting on such approval. This Agreement is terminable, without penalty, at any time, by the Adviser, by the Board, or by vote of holders of a majority of the Company’s shares on such prior notice as may be mutually agreed upon by the parties but on not more than 60 days’ written notice to the Sub-Adviser; or on at least 60 days’ written notice by the Sub-Adviser, and will terminate upon the termination of the Advisory Agreement between the Company and the Adviser. This Agreement also will terminate automatically in the event of its assignment (as defined in the 1940 Act).
