Exhibit A

Section 3 additions:

d) Under the European Union’s “Markets in Financial Instruments Directive II” (“MFID II”), the Sub-Adviser is required to provide the following reports with respect to a Fund’s UK Managed Assets (as defined in Section 5 of this Agreement):

(i) At least quarterly, a valuation report, a transaction report and a performance report each with respect to all the investments and cash comprising the Fund’s UK Managed Assets;

(ii) A notice to a Fund with UK Managed Assets and the Adviser if and when the overall value of the UK Managed Assets, as evaluated at the beginning of each reporting period, depreciates by 10%, and thereafter at multiples of 10%, by the end of the business day during which the threshold was been exceeded or, if the threshold is exceeded on a non-business day, by the end of the next business day. The Sub-Adviser will not be required to provide this notice if such depreciations are due to redemptions or other withdrawals from the Fund with UK Managed Assets; and

(iii) For each calendar year, information about all aggregated costs and charges incurred in connection with the Sub-Adviser’s discretionary investment management services and the financial instruments held in a Fund’s UK Managed Assets.

e) The Legal Entity Identifier (LEI) applicable to the JNL/JPMorgan Global Allocation Fund is: 5493006EPIXV8QL7UN39. The Adviser shall maintain the LEI and promptly notify the Sub-Adviser in the event the LEI becomes invalid, or if a different LEI becomes applicable to the JNL/JPMorgan Global Allocation Fund; and

f) The Adviser acknowledges that conflicts of interest may arise in the course of the Sub-Adviser’s providing discretionary investment management services to the Fund. Further information on the Sub-Adviser’s potential conflicts of interest and its conflicts of interest policy may be found in the Sub-Adviser’s Form ADV and/or its Financial Conduct Authority Disclosure Document, each of which have been provided to the Adviser.

5. 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 and the Adviser acknowledges that the Sub-Adviser will effect securities and other transactions through brokers of its choosing. 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 Sub-Adviser on behalf of the Funds. Sub-Adviser will provide copies of futures 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”, which means prompt and efficient execution of the transaction at the best obtainable price with payment of commissions which are reasonable in relation to the value of the brokerage services provided by the broker.

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; and the value of the expected contribution of the broker-dealer to the investment performance of the applicable Fund on a continuing basis. If the Sub-Adviser manages a portion of a Fund’s assets from its offices in the United Kingdom (“UK Managed Assets”), the brokerage commissions paid on transactions in the UK Managed Assets will compensate the broker for trade execution only. Subject to such policies and procedures as the Trust’s Board of Trustees may determine, the Sub-Adviser shall have discretion to effect investment transactions in assets the Sub-Adviser manages from its offices outside the United Kingdom (“Non-UK Managed Assets”) through broker-dealers (including, to the extent

Exhibit A-1

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 therefor.

The Adviser hereby acknowledges receipt of the current best execution policy of the Sub-Adviser’s London branch and consents to the Sub-Adviser following such policy. In addition, the Adviser agrees that the Sub-Adviser may execute trades in markets that are not “regulated markets” as that term is defined in the European Union’s MFID II and may execute orders outside a trading venue.
