NOW, THEREFORE, in consideration of the promises and the terms and conditions hereinafter set forth, the parties agree as follows:

1. Appointment of Sub‑Advisor

In accordance with and subject to the Management Agreement, the Manager hereby appoints the Sub‑Advisor to perform the services described in Section 2 below for investment and reinvestment of the securities and other assets of the Series, subject to the control and direction of the Fund's Board of Directors, for the period and on the terms hereinafter set forth. The Sub‑Advisor accepts such appointment and agrees to furnish the services hereinafter set forth for the compensation herein provided. The Sub‑Advisor shall for all purposes herein be deemed to be an independent contractor and shall, except as expressly provided or authorized, have no authority to act for or represent the Fund or the Manager in any way or otherwise be deemed an agent of the Fund or the Manager.

2. Obligations of and Services to be Provided by the Sub‑Advisor

(a) Provide investment advisory services, including but not limited to research, advice and supervision, for the Series.

(b) Furnish to the Board of Directors of the Fund (or any appropriate committee of such Board), and revise from time to time as conditions require, a recommended investment program for the portfolio of the Series consistent with the Series’ investment objective and policies as set forth in the Registration Statement, as may be amended from time to time.

c) Implement such of its recommended investment program as the Board of Directors (or any appropriate committee of the Board) shall approve, by placing orders for the purchase and sale of securities, subject always to the provisions of the Fund's Articles of Incorporation and Bylaws and the requirements of the 1940 Act, as each of the same shall be from time to time in effect.

(d) Advise and assist the officers of the Fund, as reasonably requested by the officers, in taking such steps as are necessary or appropriate to carry out the decisions of its Board of Directors, and any appropriate committees of such Board, regarding the general conduct of the investment business of the Series.

(e) Report to the Board of Directors of the Fund at such times and in such detail as the Board of Directors may deem appropriate in order to enable it to determine that the investment policies, procedures and approved investment program of the Series are being observed.

(f) Upon reasonable request, provide assistance and recommendations for the determination of the fair value of certain securities when market quotations are not readily available for purposes of calculating net asset value in accordance with procedures and methods established by the Fund's Board of Directors.

(g) Furnish, at its own expense, (i) all necessary investment and management facilities, including salaries of clerical and other personnel required for it to execute its duties faithfully, and (ii) administrative facilities, including bookkeeping, clerical personnel and equipment necessary for the efficient conduct of the investment advisory affairs of the Series. Except for expenses specifically assumed or agreed to be paid by the Sub-Advisor under this Agreement, the Sub-Advisor shall not be liable for any expenses of the Manager, the Fund or the Series including, without limitation, (i) interest and taxes, (ii) brokerage commissions and other costs in connection with the purchase or sale of securities or other investment instruments with respect to the Series, and (iii) custodian fees and expenses.

(h) Open accounts with broker-dealers and future commission merchants (“broker-dealers”), select brokers and dealers to effect all transactions for the Series (which may include brokers or dealers affiliated with the Sub-Advisor, provided such transactions comply with applicable requirements under the 1940 Act), place all necessary orders with brokers, dealers, or issuers, and negotiate brokerage commissions, if applicable. To the extent consistent with applicable law, purchase or sell orders for the Series may be aggregated with contemporaneous purchase or sell orders of other clients of the Sub-Advisor. 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 a manner the Sub-Advisor considers to be equitable and consistent with its fiduciary obligations to the Series and to other clients. The Sub-Advisor shall use its best efforts to obtain execution of transactions for the Fund at prices that are advantageous to the Fund and at commission rates that are reasonable in relation to the benefits received. In doing so, the Sub-Advisor may select brokers or dealers on the basis that they also provide brokerage, research or other services or products to the Sub-Advisor. To the extent consistent with applicable law, the Sub-Advisor may pay a broker or dealer an amount of commission for effecting a securities transaction in excess of the amount of commission or dealer spread another broker or dealer would have charged for effecting that transaction if the Sub-Advisor determines in good faith that such amount of commission is reasonable in relation to the value of the brokerage and research products and/or services provided by such broker or dealer. This determination, with respect to brokerage and research products and/or services, may be viewed in terms of either that particular transaction or the overall responsibilities which the Sub-Advisor and its affiliates have with respect to the Series

as well as to accounts over which they exercise investment discretion. Not all such services or products need be used by the Sub-Advisor in managing the Series. In addition, joint repurchase or other accounts may not be utilized by the Series except to the extent permitted under any exemptive order obtained by the Sub-Advisor and provided that all conditions of such order are complied with.

(i) Maintain all accounts, books and records with respect to the Series as are required of an investment adviser of a registered investment company pursuant to the 1940 Act and Investment Advisers Act of 1940, as amended, (the "Investment Advisers Act"), and the rules thereunder, and furnish the Fund and the Manager with such periodic and special reports as the Fund or Manager may reasonably request. In compliance with the requirements of Rule 31a-3 under the 1940 Act, the Sub-Advisor hereby agrees that all records that it maintains for the Series are the property of the Fund and it will surrender promptly to the Fund any records that it maintains for the Series upon request by the Fund or the Manager provided, however, that the Sub-Advisor may retain a copy of such records. The Sub-Advisor has no responsibility for the maintenance of Fund records except insofar as is directly related to the services provided to the Series.

(j) Observe and comply with Rule 17j-1 under the 1940 Act and the Sub-Advisor’s Code of Ethics adopted pursuant to that Rule as the same may be amended from time to time. The Manager acknowledges receipt of a copy of Sub-Advisor’s current Code of Ethics. The Sub-Advisor shall promptly forward to the Manager a copy of any material amendments to the Sub-Advisor’s Code of Ethics.

(k) From time to time as the Manager or the Fund may reasonably request, furnish the requesting party reports on portfolio transactions and reports on investments held by the Series, all in such detail as the Manager or the Fund may reasonably request. The Sub-Advisor will make available its officers and employees to meet with the Fund’s Board of Directors at reasonable times at the Fund’s principal place of business upon reasonable notice to review the investments of the Series.

(l) Provide such information as may be required for the Fund or the Manager to comply with their respective obligations under applicable laws, including, without limitation, the Internal Revenue Code of 1986, as amended (the “Code”), the 1940 Act, the Investment Advisers Act, the Securities Act of 1933, as amended (the “Securities Act”), and any state securities laws, and any rule or regulation thereunder.

(m) Maintain, in connection with the Sub-Advisor’s investment advisory services obligations provided hereunder, compliance with the 1940 Act and the regulations adopted by the Securities and Exchange Commission thereunder and each Series’ investment strategies and restrictions as stated in the Series’ current prospectus and statement of additional information.

(n) Provide to the Manager a copy of its Form ADV as filed with the Securities and Exchange Commission, as amended from time to time, and a list of the persons whom the Sub-Advisor wishes to have authorized to give written and/or oral instructions to custodians of assets of the Series.

3.    Prohibited Conduct

In providing the services described in this agreement, the Sub-Advisor will not consult with any other investment advisory firm that provides investment sub-advisory services to the Fund or a fund that is under common control with the Fund regarding transactions for the Fund in the securities or other assets allocated to the Sub-Advisor pursuant to this Agreement, except as permitted by Rule 12d-3-1 under the 1940 Act.

4.    Compensation

As full compensation for all services rendered and obligations assumed by the Sub‑Advisor hereunder with respect to the Series, the Manager shall pay the compensation specified in Appendix A to this Agreement. Although the Manager may from time to time waive the compensation it is entitled to receive from the Series, such waiver will have no effect on the Manager’s obligation to pay the Sub-Advisor the compensation provided for herein.

5.    Liability of Sub‑Advisor

Neither the Sub‑Advisor nor any of its directors, officers or employees shall be liable to the Manager, the Fund, the Series or any shareholder of the Fund for any loss suffered by the Manager, the Fund, the Series or any shareholder of the Fund resulting from any error of judgment made in the good faith exercise of the Sub‑Advisor's investment discretion in connection with selecting investments for the Series except for losses resulting from willful misfeasance, bad faith or gross negligence of, or from reckless disregard of, the duties of the Sub‑Advisor or any of its directors, officers or employees. The Manager shall hold harmless and indemnify the Sub-Advisor for any loss, liability, cost, damage or expense (including reasonable attorneys fees and costs) arising from any claim or demand by any past or present shareholder of the Series or the Fund that is not based upon the obligations of the Sub-Advisor with respect to the Series under this Agreement. The Manager acknowledges and agrees that the Sub-Advisor makes no representation or warranty, express or implied, that any level of performance or investment results will be achieved by the Series or that the Series will perform comparably with any standard or index, including other clients of the Sub-Advisor, whether public or private.

6.    Supplemental Arrangements

The Sub‑Advisor may enter into arrangements with other persons affiliated with the Sub‑Advisor for the provision of certain personnel and facilities to the Sub-Advisor to better enable it to fulfill its obligations under this Agreement.
