Amended and Restated

This Amended and Restated Sub-Advisory Agreement (the “Agreement”) is made as of the 1^st day of September, 2022, by and between Xxxxxxx National Asset Management, LLC, a Michigan limited liability company (the “Adviser”), and Dimensional Fund Advisors LP, a Delaware limited partnership and registered investment adviser (the “Sub-Adviser”).

Whereas, the Adviser is registered as an investment adviser under the Investment Advisers Act of 1940, as amended (the “Advisers Act”);

Whereas, the Sub-Adviser is registered as an investment adviser under the Advisers Act;

Whereas, the Adviser has entered into an Amended and Restated Investment Advisory and Management Agreement, effective September 13, 2021, with JNL Series Trust (the “Trust”), an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”), consisting of multiple series (each, a “Fund”);

Whereas, the Board of Trustees of the Trust (the “Board of Trustees”) and the Adviser retained the Sub-Adviser to render investment advisory services pursuant to the terms of a Sub-Advisory Agreement, effective September 13, 2021, as amended (the “Original Sub-Advisory Agreement”); and

Whereas, the Board of Trustees and the Adviser desire that the Adviser retain the Sub-Adviser to render investment advisory services for the portion of each Fund’s assets allocated to the Sub-Adviser listed on Schedule A attached hereto, as determined from time to time by the Adviser, and also desire in combination with the Sub-Adviser to amend and restate the Original Sub-Advisory Agreement, in the manner and on the terms set forth herein.

Now, Therefore, in consideration of the mutual covenants herein contained, the parties hereto agree as follows:

Appointment. The Adviser hereby appoints the Sub-Adviser to provide certain sub-investment advisory services to the Funds for the period and on the terms set forth in this Agreement. The Sub-Adviser accepts such appointment and agrees to furnish the services herein set forth for the compensation herein provided.

In the event the Adviser designates one or more funds other than the Funds with respect to which the Adviser wishes to retain the Sub-Adviser to render investment advisory services hereunder, it shall notify the Sub-Adviser in writing. If the Sub-Adviser is willing to render such services, the parties agree to execute an amended Schedule A of this Agreement, whereupon such fund shall become a Fund hereunder, and shall be subject to this Agreement, subject to the approval of the Board of Trustees.

Delivery of Documents. The Adviser has or will furnish the Sub-Adviser with copies properly certified or authenticated of each of the following prior to the commencement of the Sub-Adviser’s services:

the Trust’s Agreement and Declaration of Trust, as filed with the Secretary of State of The Commonwealth of Massachusetts on June 1, 1994, and all amendments thereto or restatements thereof (such Declaration, as presently in effect and as it shall from time to time be amended or restated, is herein called the “Declaration of Trust”);

the Trust’s By-Laws and amendments thereto;

resolutions of the Board of Trustees authorizing the appointment of the Sub-Adviser and approving this Agreement;

the Trust’s Notification of Registration on Form N-8A under the 1940 Act as filed with the Securities and Exchange Commission (the “SEC”) and all amendments thereto;

the Trust’s Registration Statement on Form N-1A under the Securities Act of 1933, as amended (“1933 Act”) and under the 1940 Act as filed with the SEC and all amendments thereto insofar as such Registration Statement and such amendments relate to the Funds; and

the Trust’s most recent prospectus and Statement of Additional Information for the Funds (collectively called the “Prospectus”).

During the term of this Agreement, the Adviser agrees to furnish the Sub-Adviser all prospectuses, Statements of Additional Information, proxy statements, reports to shareholders, sales literature or other materials prepared for distribution to shareholders of each Fund, prior to the use thereof, and the Adviser shall not use any such materials if the Sub-Adviser reasonably objects in writing within ten business days (or such other period as may be mutually agreed) after receipt thereof. The Sub-Adviser’s right to object to such materials is limited to the portions of such materials that expressly relate to the Sub-Adviser, its services and its clients. The Adviser agrees to use its reasonable best efforts to ensure that materials prepared by its employees or agents or its affiliates that refer to the Sub-Adviser or its clients in any way are consistent with those materials previously approved by the Sub-Adviser as referenced in the first sentence of this paragraph. Sales literature may be furnished to the Sub-Adviser by e-mail, first class or overnight mail, facsimile transmission equipment or hand delivery.

The Adviser will furnish the Sub-Adviser with copies of all amendments of or supplements to the documents identified in the immediately preceding paragraph that relate specifically to the Sub-Adviser or a Fund that it provides sub-advisory services to, within a reasonable time prior to use thereof. Any amendments or supplements that impact the management of the Funds will not be deemed effective with respect to the Sub-Adviser until the Sub-Adviser’s approval thereof.

Management. Subject always to the supervision of the Adviser, who in turn is subject to the supervision of the Board of Trustees, the Sub-Adviser will furnish an investment program in respect of, and make investment decisions for, all assets of the Funds and place all orders for the purchase and sale of securities, including foreign or domestic securities or other property (including financial futures and options of any type), all on behalf of the Funds. In the performance of its duties, the Sub-Adviser will satisfy its fiduciary duties to the Funds (as set forth below), and will monitor the Funds’ investments, and will comply with the provisions of Trust’s Declaration of Trust and By-Laws, as amended from time to time and as provided to the Sub-Adviser pursuant to Section 2 of this Agreement, and the stated investment objectives, policies and restrictions of the Funds, which may be amended from time to time. The Sub-Adviser, solely with respect to the assets of the Funds which are under its management pursuant to this Agreement, and based on information obtained from the Funds’ administrator, custodian and other service providers, shall take reasonable steps to comply with the diversification provisions of Section 851(b)(3) and Section 817(h) of the Internal Revenue Code of 1986, as amended (“IRC”), and its accompanying Regulation, Treas. Reg. Section 1.817-5, applicable to the Funds.

Page 2 of 11

The Adviser will not act in a manner that would prevent the Sub-Adviser from taking reasonable steps to comply with the diversification provisions identified in the above paragraph and if the failure to diversify is inadvertent, Xxxxxxx National Life Insurance Company and any of its affiliates investing in the Funds, as owner of the assets in the Funds, shall in good faith follow the procedures specified in Treas. Reg. Section 1.817-5(a)(2) and Revenue Procedure 92-25 (or its successor) to request relief from the Commissioner of Internal Revenue Service, and that in such an event the Sub-Adviser will provide reasonable cooperation to the Adviser in the Adviser’s preparation of any request for relief or closing agreement and, to the extent that Adviser is seeking indemnification under Section 11 hereof, no filings or agreements shall be made with the Commissioner of Internal Revenue Service without the prior written approval of the Sub-Adviser.

The Sub-Adviser is authorized to negotiate and execute documentation relating to Fund investments. Such documentation may relate to Fund investments to be made or sold, currently held or previously held. The authority shall include, without limitation: (i) documentation relating to private placements; and (ii) documentation for any election on corporation actions that the Sub-Adviser makes with respect to portfolio securities held in a Fund. The Adviser represents that each Fund can settle such private placements.

The Sub-Adviser further agrees that it:

will use the same skill and care in providing such services as it uses in providing services to its other client mandates for which it has investment responsibilities;

will comply with all applicable Rules and Regulations of the SEC in all material respects and in addition will conduct its activities under this Agreement in accordance with any applicable regulations of any governmental authority pertaining to its investment advisory activities, including but not limited to compliance with Rule 206(4)-7 under the Investment Advisers Act of 1940, as amended;

will comply in all material respects with all foreign laws, regulations, and regulatory requirements as set forth by foreign regulatory agencies, as applicable;

will report regularly to the Adviser and to the Board of Trustees as reasonably agreed between the Adviser and the Sub-Adviser and will make appropriate persons available for the purpose of reviewing with representatives of the Adviser and the Board of Trustees on a regular basis at reasonable times, and with reasonable advance notice, as may be agreed to by the Adviser and the Sub-Adviser, the management of the Funds, including, without limitation, review of the general investment strategies of the Funds, the performance of the Funds in relation to the specified benchmarks and will provide various other reports from time to time as may be reasonably requested by the Adviser in writing;

Page 3 of 11

will provide to the Adviser (i) a monthly compliance checklist developed for each Fund by the Adviser and the Sub-Adviser, (ii) quarterly reports developed for each Fund by the Adviser and the Sub-Adviser, and (iii) other compliance and reporting information as reasonable requested by the Adviser or the Board of Trustees, and agreed to by the Sub-Adviser, from time-to-time (with regard to this sub-section (iii) only);

as a service provider to the Funds will periodically provide information, including information about the Sub-Adviser’s compliance program adopted pursuant to Rule 206(4)-7 under the Investment Advisers Act, as may be reasonably requested by the Chief Compliance Officer of the Trust in the execution of his/her responsibilities to monitor service providers to the Funds under Rule 38a-1 under the 1940 Act including any applicable document requests;

will prepare and maintain such books and records with respect to each Fund’s securities transactions in accordance with Section 7 herein;

will prepare and cause to be filed in a timely manner Form 13F and, if required, Schedule 13G with respect to securities held for the account of the Funds subject to the Sub-Adviser’s supervision;

will act upon reasonable instructions from the Adviser (except as to the voting of proxies) not inconsistent with the Sub-Adviser’s fiduciary duties or a Fund’s investment objectives; however, in no case shall the Sub-Adviser be liable for actions taken or non-actions with respect to the performance of services under this Agreement based upon specific information, instructions or requests given or made to the Sub-Adviser by the Adviser;

consistent with its fiduciary duties to each Fund and on the Fund’s behalf, the Sub-Adviser is hereby appointed the Fund’s agent to exercise in its direction all rights and performs all duties with respect to the Fund’s right to vote (or refrain from voting), each Fund’s securities, provided that the Sub-Adviser has received the relevant proxy materials in a timely fashion, in accordance with the Sub-Adviser’s proxy voting guidelines, as amended from time to time, which shall be provided to the Trust and the Adviser. For the avoidance of doubt, the Sub-Adviser will have full discretion in this regard and the Adviser will not attempt to influence the Sub-Adviser’s voting decisions. The Sub-Adviser monitors for significant shareholder obligations for its aggregate managed account holdings and will seek to report significant shareholdings based on its aggregate managed account holdings where required to be reported by the Sub-Adviser under local law. For the avoidance of doubt, the Sub-Adviser shall not be required to consider investments held by a Fund that are not managed by the Sub-Adviser and also will not make filings on behalf of a Fund if the Fund itself becomes subject to a significant shareholder reporting requirement. The Sub-Adviser will have the power to exercise rights, options, warrants, conversion privileges, and redemption privileges, and to tender securities pursuant to a tender offer, consistent with the Sub-Adviser’s fiduciary duties hereunder;

Page 4 of 11

may not consult with any other sub-adviser of the Trust concerning transactions in securities or other assets for any investment portfolio of the Trust, including the Funds, except that such consultations are permitted between the current and successor sub-advisers of the Funds in order to effect an orderly transition of sub-advisory duties so long as such consultations are not concerning transactions prohibited by Section 17(a) of the 1940 Act or except as otherwise may be permitted by law; and

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

The Adviser acknowledges and agrees that the Sub-Adviser will not be responsible to advise or act for a Fund in any legal proceedings, including bankruptcies and class action proceedings, related to assets currently or previously held by the Fund.

The Adviser and the Sub-Adviser each further agree that:

Adviser and Sub-Adviser shall seek to have the Fund operated and monitored in compliance with the trading limitations and marketing restrictions set forth in the Commodity Exchange Act (“CEA”) and Regulation 4.5(c)(2)(iii) of the then-current Commodity Futures Trading Commission (“CFTC”) regulations, and (ii) shall promptly notify the other upon any indication that the Fund is not in compliance with such trading limitations or marketing restrictions; and (iii) shall take immediate steps to remediate any such non-compliance, in consultation with the other party; and

Adviser, with such reasonable assistance of the Sub-Adviser as may be requested by Adviser, shall assure that notices of exclusion of exemption applicable to the Fund are filed with the National Futures Association (“NFA”) as required by CFTC Regulation 4.5.

Custody of Assets. The Sub-Adviser shall at no time have the right to physically possess the assets of the Funds or have the assets registered in its own name or the name of its nominee, nor shall the Sub-Adviser in any manner acquire or become possessed of any income, whether in kind or cash, or proceeds, whether in kind or cash, distributable by reason of selling, holding or controlling such assets of the Funds. In accordance with the preceding sentence, the Sub-Adviser shall have no responsibility with respect to the collection of income, physical acquisition or the safekeeping of the assets of the Funds. All such duties of collection, physical acquisition and safekeeping shall be the sole obligation of the Fund’s custodian.

Brokerage. The Sub-Adviser is responsible for decisions to buy and sell securities for each Fund, broker-dealer selection, and negotiation of brokerage commission rates. The Sub-Adviser shall have the express authority to negotiate, open, continue and terminate brokerage accounts and other brokerage arrangements with respect to all portfolio transactions entered into by the Sub-Adviser on behalf of the Funds. The Sub-Adviser will, upon request of the Adviser, provide copies of brokerage agreements entered into by the Funds to the Adviser, if applicable. It is the Sub-Adviser’s general policy in selecting a broker to effect a particular transaction to seek to obtain “best execution”, consistent with applicable law and the Sub-Adviser’s relevant policies and procedures.

Page 5 of 11

Consistent with this policy, the Sub-Adviser, in selecting broker-dealers and negotiating commission rates, will take all relevant factors into consideration, including, but not limited to: the best price available; the reliability, integrity and financial condition of the broker-dealer; the size of and difficulty in executing the order; the broker’s execution capabilities and any research provided by the broker that aids the Sub-Adviser’s investment decision-making process; and the value of the expected contribution of the broker-dealer to the investment performance of the applicable Fund on a continuing basis. Subject to the Sub-Adviser’s relevant policies and procedures, as provided in advance to the Adviser, the Sub-Adviser shall have discretion to effect investment transactions for each Fund through broker-dealers (including, to the extent permissible under applicable law, broker-dealer affiliates) who provide brokerage and/or research services, as such services are defined in section 28(e) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), and to cause such Fund to pay any such broker-dealers an amount of commission for effecting a portfolio investment transaction in excess of the amount of commission another broker-dealer would have charged for effecting that transaction, if the Sub-Adviser determines in good faith that such amount of commission is reasonable in relation to the value of the brokerage or research services provided by such broker-dealer, viewed in terms of either that particular investment transaction or the Sub-Adviser’s overall responsibilities with respect to such Fund and other accounts to which the Sub-Adviser exercises investment discretion (as such term is defined in section 3(a)(35) of the 1934 Act). Allocation of orders placed by the Sub-Adviser on behalf of a Fund to such broker-dealers shall be in such amounts and proportions as the Sub-Adviser shall determine in good faith in conformity with its responsibilities under applicable laws, rules and regulations. The Sub-Adviser will submit reports on brokerage placements to the Adviser as reasonably requested by the Adviser, in such form as may be mutually agreed to by the parties hereto, indicating the broker-dealers to whom such allocations have been made and the basis therefore.

Consistent with the Sub-Adviser’s relevant policies and procedures, the Sub-Adviser may group orders for a Fund with orders for other funds and accounts advised or sub-advised by the Sub-Adviser or its affiliates, as provided in advance to the Adviser, to obtain the efficiencies that may be available on larger transactions when it determines that investment decisions are appropriate for each participating account. The Sub-Adviser cannot assure that such policy will not adversely affect the price paid or received by a Fund. The Adviser recognizes, and has advised the Board of Trustees, that in some cases this procedure may adversely affect the size and the opportunities of the position that the participating Fund may obtain in a particular security.

Expenses. The Sub-Adviser shall bear all expenses incurred by it in connection with the performance of its services under this Agreement. Each Fund will bear certain other expenses to be incurred in its operation, including, but not limited to, investment advisory fees, and administration fees; fees for necessary professional and brokerage services; costs relating to local administration of securities; and fees for any pricing services. All other expenses not specifically assumed by the Sub-Adviser hereunder or by the Adviser under the Management Agreement are borne by the applicable Fund or the Trust.

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 Trust shall be the property of the Trust and agrees to provide the Trust with copies of any of such records promptly upon the Trust’s request. The Sub-Adviser further agrees to preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the records required to be maintained by Rule 31a-1 under the 1940 Act related to each Fund’s portfolio transactions and that are not maintained by the Fund’s custodian. The Adviser shall maintain all books and records not related to the Fund’s portfolio transactions.

Page 6 of 11

Compensation. For the services provided and the expenses assumed 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 accrued daily and payable monthly on the average daily net assets in the Funds in accordance with Schedule B hereto. Expense caps or fee waivers for a Fund that may be agreed to by the Adviser, but not agreed to in writing by the Sub-Adviser, shall not cause a reduction in the amount of payment to the Sub-Adviser.

Services to Others. The Adviser understands, and has advised the Board of Trustees, that the Sub-Adviser now acts, or may in the future act, as an investment adviser to fiduciary and other managed accounts, and as investment adviser or sub-investment adviser to other investment companies or accounts. The Adviser has no objection to the Sub-Adviser acting in such capacities, provided that whenever the Fund and one or more other investment advisory clients of the Sub-Adviser have available funds for investment, investments will be allocated in a manner that is consistent with the Sub-Adviser’s relevant policies and procedures, as provided in advance to the Adviser. In addition, the Adviser understands, and has advised the Board of Trustees, that the persons employed by the Sub-Adviser to assist in the Sub-Adviser’s duties under this Agreement will not devote their full time to such service and nothing contained in this Agreement will be deemed to limit or restrict the right of the Sub-Adviser or any of its affiliates to engage in and devote time and attention to other businesses or to render services of whatever kind or nature.

10.

Limitation of Liability. The Sub-Adviser, its officers, directors, employees, agents or affiliates will not be subject to any liability to the Adviser or the Funds or their directors, officers, employees, agents or affiliates for any error of judgment or mistake of law or for any loss suffered by the Funds, any shareholder of the Funds or the Adviser either in connection with the performance of the Sub-Adviser’s duties under this Agreement or its failure to perform due to events beyond the reasonable control of the Sub-Adviser or its agents, except for a loss resulting from the Sub-Adviser’s willful misfeasance, or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under this Agreement. Federal and State securities laws may impose liabilities under certain circumstances on persons who act in good faith, and therefore nothing herein shall in any way constitute a waiver or limitation of any right which Adviser may have under any applicable laws.

11.

Indemnification. The Adviser and the Sub-Adviser each agree to indemnify the other party (and each such party’s affiliates, employees, directors and officers) against any claim, damages, loss or liability (including reasonable attorneys’ fees) arising out of any third party claims brought against an indemnified party that is based upon the willful misfeasance or gross negligence on the part of the indemnifying party.

12.

Duration and Termination. This Agreement will become effective as to a Fund upon execution or, if later, on the date that initial capital for such Fund is first provided to it and, unless sooner terminated as provided herein, the initial term will continue in effect through September 30, 2023. Thereafter, if not terminated as to a Fund, this Agreement will continue from year to year through September 30^th of each successive year following the initial term, for each Fund covered by this Agreement, as listed on Schedule A, provided that such continuation is specifically approved at least annually by the Board of Trustees or by vote of a majority of the outstanding voting securities of such Fund(s), and in either event approved also by a majority of the Trustees of the Trust who are not interested persons of the Trust, or of the Adviser, or of the Sub-Adviser (“Independent Trustees”). Notwithstanding the foregoing, this Agreement may be terminated as to a Fund at any time, without the payment of any penalty, by the Board of Trustees, including a majority of the Independent Trustees, or by the vote of a majority of the outstanding voting securities of each Fund, on sixty days’ written notice to the Adviser and the Sub-Adviser, or by the Adviser with the consent of the Board of Trustees (including a majority of the Independent Trustees), or on sixty days’ written notice by the Sub-Adviser to the Trust and the other party. This Agreement will immediately terminate in the event of its assignment. (As used in this Agreement, the terms “majority of the outstanding voting securities”, “interested persons” and “assignment” have the same meaning of such terms as in the 1940 Act.) Section 10 and 11 herein shall survive the termination of this Agreement.

13.

Acknowledgements of the Adviser. The Adviser acknowledges and agrees that:

If the Sub-Adviser is registered as a Commodity Trading Advisor under the CEA, the Adviser consents to the Sub-Adviser’s compliance with the alternative disclosure and recordkeeping standards available to exempt accounts under CFTC Rule 4.7 with respect to a Fund’s trading in commodity interests, provided that the Sub-Adviser has duly filed a notice of claim for such relief pursuant to Rule 4.7(d). The Adviser will take reasonable steps to cooperate with the Sub-Adviser in connection with establishing and maintaining such exemption under Rule 4.7, including, upon request, confirming whether a Fund is a “qualified eligible person” as defined in Rule 4.7.

If the Adviser is excluded from the definition of a commodity pool operator under CFTC Rule 4.5 with respect to a Fund, the Adviser will furnish the Sub-Adviser with a copy of the notice of eligibility filed pursuant to Rule 4.5 (c) with respect to such exclusion, or, if more recent, the most recent annual notice affirming the basis of such eligibility that has been filed pursuant to Rule 4.5(c)(5).
