THIS INVESTMENT SUB-ADVISORY AGREEMENT (the “Agreement”) is made as of May 3, 2021, by and between SECURIAN ASSET MANAGEMENT, INC., a Minnesota corporation (the “Adviser”), and DELAWARE INVESTMENTS FUND ADVISERS, A SERIES OF MACQUARIE INVESTMENT MANAGEMENT BUSINESS TRUST, a Delaware statutory trust (the “Sub-Adviser”).

RECITALS

WHEREAS, the Adviser and Sub-Adviser are each registered investment advisers with the U.S. Securities and Exchange Commission (the “SEC”) under the Investment Advisers Act of 1940, as amended (the “Advisers Act”);

WHEREAS, the Adviser is the investment adviser to Securian Funds Trust (the “Trust”), each of whose series or funds operates as an open-end investment management company registered under the Investment Company Act of 1940, as amended (the “1940 Act”), pursuant to an Investment Advisory Agreement by and between the Adviser and the Trust (as the same may be amended from time to time, the “Investment Advisory Agreement”); and

WHEREAS, the Adviser desires to retain the Sub-Adviser to furnish certain investment advisory and management services to the Trust’s SFT – Ivy Growth Fund and SFT – Ivy Small Cap Growth Fund (each a “Fund”, and collectively, the “Funds”), and the Sub-Adviser desires to furnish such services to the Adviser on the terms and conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the mutual premises and covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Sub-Adviser and Adviser agree as follows:

1. Appointment. In accordance with and subject to the Investment Advisory Agreement, the Adviser hereby appoints the Sub-Adviser to provide the investment advisory and management services described herein, including the investment and reinvestment of the Funds, subject to the control and direction of the Trust’s Board of Trustees (the “Board”), for the duration and on the terms set forth herein. The Sub-Adviser accepts such appointment and agrees to furnish the services set forth herein, in consideration of the compensation set forth on the Schedule of Fees (as defined below). The Sub-Adviser shall for all purposes herein be deemed to be an independent contractor and shall, except as expressly provided or authorized herein, have no authority to act for or represent the Trust or the Adviser in any way or otherwise be deemed an agent of the Trust or the Adviser. Notwithstanding the foregoing, to enable the Sub-Adviser to fully exercise its

1

Execution Version

discretion, the Adviser hereby appoints the Sub-Adviser as agent and attorney-in-fact for the Funds, limited to the power and authority necessary, as determined by the Sub-Adviser, to buy, sell and otherwise deal in securities and contracts for the Funds, subject to the terms and conditions of this Agreement.

2. Duties of Sub-Adviser. Subject always to the direction and control of the Board, the Sub-Adviser will manage the investments and determine the composition of the assets of the Funds in accordance with each Fund’s investment objective, investment policies and limitations set forth in the Trust’s registration statement (as the same may be amended from time to time, the “Registration Statement”), or as subsequently amended in writing. In fulfilling its obligations to manage the investments and reinvestments of the assets of the Funds, the Sub-Adviser will:

a. Investment Plan

i. obtain and evaluate pertinent economic, statistical, financial and other information affecting the economy generally and individual companies or industries the securities of which are included in the Fund or are under consideration for inclusion therein;

ii. formulate and implement a continuous investment program for the Funds consistent with the investment objective and related investment policies for such Fund as set forth in the Registration Statement;

iii. take such steps as are necessary to implement the aforementioned investment program by purchase and sale of securities and other instruments, including the placing of orders for such purchases and sales, entering into derivative transactions (if applicable) and by managing all cash in the Funds;

iv. if applicable, purchase, sell, exchange or convert foreign currency in the spot or forward markets in connection with portfolio trades as agent, at the market rate, as determined by the Sub-Adviser in its sole discretion. Conversion of currencies into and out of the base currency of the Fund in restricted markets and, unless agreed otherwise by the Sub-Adviser, generally income repatriation transactions will be the responsibility of the Fund’s custodian (the “Custodian”), not of the Sub-Adviser. To the extent the Custodian performs such transactions, the Sub-Adviser shall not have the ability to control such transactions and will be limited in its ability to assess the quality of such transactions. In addition, whether a market is considered to be restricted will depend on a number of factors, including, but not limited to, country specific statutory documentation requirements, country specific structural risks and convertibility issues. Accordingly, the Sub-Adviser shall be entitled to consult with third parties, including, but not limited to, broker-dealers and custodians, and rely upon such information in making a good faith determination on whether a market is considered restricted.

v. if applicable, manage required collateral levels in connection with the investment and reinvestment of the assets of the Funds. If applicable, the Sub-Adviser will provide instructions to the Custodian to post collateral and to call for collateral from counterparties, as necessary, and will arrange for the transmission to the Custodian on a daily basis such confirmation, trade tickets, and other identifying information (including, but not limited to, CUSIP, Sedol, or other numbers that identify the securities to be purchased or sold on behalf of the Funds) as may be reasonably necessary to enable the Custodian to perform its administrative and recordkeeping responsibilities with respect to the Fund. If applicable, the Sub-Adviser will provide reports with respect to its collateral management activities as requested by the Adviser;

vi. regularly report to the Board with respect to the implementation of these investment programs;

vii. provide reasonable assistance to the Adviser, the Trust, or the Custodian, or each of their respective delegates regarding the assessment of the fair value of securities held by the Funds for which market quotations are not readily available, or which may be identified by review, from time to time, by either the Trust or the Adviser;

viii. notify Adviser of securities in the Funds that are fair valued by the Sub-Adviser pursuant to the Sub-Adviser’s valuation policies;

ix. review portions of the Registration Statement applicable to the Funds or the Sub-Adviser on an annual basis and provide proposed revisions to Adviser;

x. provide reasonable input to the Adviser and the Funds with regards to the Adviser and Fund’s duties for certain operational services for the Funds, including, without limitation, the following: (a) the preparation of tax returns; (b) the preparation and submission of reports to the shareholders of the Funds; (c) periodic updates to those portions of the Prospectus and Statement of Additional Information of the Trust relevant to the Funds; and (d) the preparation of reports to be filed with the SEC and other regulatory authorities; and

b. Investment Objectives, Policies and Restrictions.

In managing the investments of and determining the composition of its portion of the assets of the Fund and in performing its other services and obligations hereunder, the Sub-Adviser shall: (i) be subject to the applicable provisions of the Agreement and Declaration of Trust, the Bylaws, the Registration Statement, the current Prospectus and Statement of Additional Information; (ii) comply with the investment objectives, policies and restrictions of the Fund as set forth in the Registration Statement, as from time to time amended or supplemented; (iii) comply with all policies, guidelines, instructions and procedures approved by the Board or the Adviser with respect to the Fund and furnished to the Sub-Adviser; (iv) comply with all applicable requirements of the Advisers Act, the 1940 Act and the rules and regulations under each thereof, as the same may be amended from time to time; (v) cause the Fund to comply with (x) the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), for qualification as a regulated investment company (if and for so long as the Fund seeks to qualify as a regulated investment company under the Code) and (y) the diversification requirements under Subchapter L, including the requirements of Regulation 1.817-5, of the Code; and (vi) comply with all other applicable law, rules and regulations. In addition, the Sub-Adviser shall maintain compliance procedures in connection with its services for the Fund that the Sub-Adviser reasonably believes are adequate to ensure its compliance with the foregoing.

In no event shall Sub-Adviser cause the Fund to enter into derivative transactions that would cause the Fund to exceed the de minimus test for commodity pool operator registration set forth in Commodity Futures Trading Commission (“CFTC”) Regulation 4.5.

c. Cash Management and Short-Term Investment Funds

The Adviser shall arrange with the Custodian to have at least one (1) Short-Term Investment Fund (“STIF”) available to be used as a sweep vehicle for the short-term investment of cash for the Fund. The Sub-Adviser agrees to use this STIF for the short-term investment of cash, subject to the limitations on investments in shares of other investment companies set forth in the 1940 Act.

d. Electronic Delivery of Daily Trade File and Daily Holdings.

In connection with the purchase and sale of securities of the Fund, the Sub-Adviser shall deliver to the Fund’s accountant (the “Fund Accountant”), by no later than 6:00 p.m. Central Time (7:00 p.m. New York time) on each trading day, trading data in a mutually agreeable manner with respect to securities and other instruments purchased or sold on such trading day, if any, using a secure electronic system established by the Fund Accountant.

each trading day. There may be times that the Sub-Adviser will choose to trade while the futures markets are open, but it is too late in the day to meet that deadline, in which case the Sub-Adviser will develop a process with the Fund Accountant to ensure such trades are properly reported in a mutually acceptable manner. Using a secure electronic system established by Adviser, Sub-Adviser will deliver to Adviser by no later than 12:00 p.m. Central Time (1:00 p.m. New York time) on trade date plus one, a complete list of investments held by the Fund on a daily basis. Sub-Adviser agrees to reconcile these holdings with the Custodian on a monthly basis.

Revisions to or cancellations of trades must be provided by Sub-Adviser to the Fund Accountant using a secure electronic system established by the Fund Accountant by no later than 2:00 p.m. Central Time (3:00 p.m. New York time) on trade date plus one. If a revision or cancellation is made after this deadline, Sub-Adviser will promptly notify the Fund Accountant.

e. Investment in New Securities.

Sub-Adviser shall provide assistance to the Adviser and the Custodian, and any such other parties as the Adviser may reasonably request from time to time, to enable the proper set up of new securities purchased by the Fund on the date of the trade.

f. Trade Affirmation and Settlement.

i. The Sub-Adviser shall affirm and direct the Custodian to settle each trade made by the Sub-Adviser on behalf of the Fund and shall advise brokers to list Adviser as an Interested Party on all Depository Trust Company (“DTC”) confirms, supplying Adviser’s DTC number as 71567.

Execution Version

iv. Sub-Adviser agrees to monitor any failing trades and to use its best efforts to work proactively to resolve these issues, and seek reimbursement from third parties as appropriate. Sub-Adviser agrees to reimburse the Fund for any compensating interest due because of failing trades if due to the fault of Sub-Adviser.

g. Corporate and Class Actions.

i. Sub-Adviser has the obligation to determine the Fund’s participation in voluntary corporate actions, including mergers, acquisitions, tender offers, conversions, exchanges, stock splits, rights offerings, recapitalizations, and any other similar voluntary corporate action, and will work with appropriate parties to facilitate voluntary corporate action processing.

ii. Sub-Adviser shall have no responsibility for filing claims on behalf of the Adviser or the Trust with respect to any class action, bankruptcy proceeding or any other action or proceeding in which the Adviser or the Trust may be entitled to participate as a result of the Fund’s security holdings. The Sub-Adviser’s responsibility with respect to such matters shall be limited to reasonably cooperating with the Adviser and the Custodian in allowing the Adviser and Custodian to make such filings and to using its best efforts in sharing applicable information regarding such matters with the Adviser and the Custodian.

h. Proxy Voting.

Sub-Adviser shall have the sole authority and responsibility for voting all proxies on behalf of the securities held by the Fund in accordance with the Sub-Adviser’s proxy voting policies and procedures that are provided by the Sub-Adviser and adopted by the Trust. Notwithstanding the foregoing, Sub-Adviser agrees it shall consult with Adviser, as may be reasonably requested, on proxy voting matters. Subject to applicable SEC rules and guidance, the Sub-Adviser may use recommendations from a third-party in order to make voting decisions and may use a third-party service provider to perform the voting (a “Third-Party Proxy Voting Service Provider”). The Custodian or the Adviser, as the case may be, shall cause to be forwarded to the Sub-Adviser or Third-Party Proxy Voting Service Provider all proxy solicitation materials the Fund may receive. The Sub-Adviser acknowledges and agrees it has adopted written proxy voting procedures that comply with the requirements of the Advisers Act. The Sub-Adviser further agrees it shall provide Adviser, the Trust, or the Board, with all proxy voting records relating to the securities held by the Fund and with a written report of the proxies voted during the most recent twelve (12) month period or such other period as the Adviser or Trust may designate, in a format reasonably requested by the Adviser or Trust. Notwithstanding the foregoing, upon reasonable request Sub-Adviser shall provide the Adviser with all proxy voting records relating to the assets held by the Fund. The Sub-Adviser shall also provide an annual certification, in form and substance reasonably acceptable to Adviser and the Trust, attesting to the accuracy and completeness of such proxy voting records.

i. Commission Recapture.

Sub-Adviser understands that Adviser may, on occasion, enter into agreements for commission recapture with certain brokers. Sub-Adviser agrees to follow Adviser’s direction regarding commission recapture subject to best execution and applicable laws and regulations including those of self-regulatory organizations.

j. Broker Selection.

The Sub-Adviser will select brokers, dealers, futures commission merchants and other counterparties to effect all transactions for the Fund, including without limitation, with respect to transactions in securities, derivatives, foreign currency exchange, commodities and/or any other investments. The Sub-Adviser will place all orders with brokers, dealers, counterparties or issuers, and will negotiate brokerage commissions, spreads and other financial and non-financial terms, as applicable. The Sub-Adviser will always seek the best possible price and execution in the circumstances in all transactions. Subject to the foregoing, the Sub-Adviser is directed at all times to seek to execute transactions for the Fund in accordance with its trading policies, as disclosed by the Sub-Adviser to the Fund from time to time, but in all cases subject to policies and practices established by the Fund and described in the Trust’s registration statement. Notwithstanding the foregoing, the Sub-Adviser may pay a broker-dealer that provides research and brokerage services a higher spread or commission for a particular transaction than otherwise might have been charged by another broker-dealer to the extent permitted by Section 28(e) of the Securities Exchange Act of 1934 and by the Trust’s registration statement, if the Sub-Adviser determines that the higher spread or commission is reasonable in relation to the value of the brokerage and research services that such broker-dealer provides, viewed in terms of either the particular transaction or the Sub-Adviser’s overall responsibilities with respect to accounts managed by the Sub-Adviser. The Sub-Adviser may use for the benefit of the Sub-Adviser’s other clients, or make available to companies affiliated with the Sub-Adviser or to its directors for the benefit of its clients, any such brokerage and research services that the Sub-Adviser obtains from brokers or dealers.

k. Books and Records.

The Sub-Adviser will maintain all accounts, books and records with respect to its services for the Fund as are required of an investment adviser of a registered investment company pursuant to the 1940 Act, the Advisers Act, and the rules thereunder. All records pertaining to the Sub-Adviser’s management of the Fund shall be the joint property of the Trust and the Sub-Adviser and shall be available for inspection and use, upon reasonable notice and during normal business hours, by the Securities and Exchange Commission, state regulators, Adviser, or any person retained by the Trust. Where applicable, such records shall be maintained by the Sub-Adviser for the period and in the place required by Rule 31a-2 under the 1940 Act.

l. Investment Activity and Portfolio Composition Reporting.

The Sub-Adviser shall render such reports to the Adviser and/or to the Board concerning the investment activity and portfolio composition of the Fund in such form and at such intervals as the Adviser or the Board may from time to time reasonably request.

m. Aggregation of Trades and Trade Allocations.

On occasions when the Sub-Adviser deems the purchase or sale of a security to be in the best interest of the Fund as well as other customers, the Sub-Adviser, to the extent permitted by applicable law and as provided in its policies and procedures and as described in the Sub-Adviser’s Form ADV Part 2A, may, but is not required to, aggregate the securities to be so sold or purchased in order to obtain the best execution, lower brokerage commissions, or lower costs of execution, if any. The Sub-Adviser also may purchase or sell a particular security for one or more customers in different amounts. On either occasion, and to the extent permitted by applicable law and regulations, 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 it considers to be the most equitable and consistent with its fiduciary obligations to the Fund and to such other customers. In no instance, however, will the Fund’s assets be purchased from or sold to the Adviser, the Sub-Adviser, the Trust’s principal underwriter, or any affiliated person of either the Trust, the Adviser, the Sub-Adviser or the principal underwriter, acting as principal in the transaction, except to the extent permitted by the SEC and the 1940 Act.

n. Code of Ethics.

Sub-Adviser shall adopt a written code of ethics that complies with the requirements of Rule 204A-1 under the Advisers Act and Rule 17j-1 under the 1940 Act (the “Code of Ethics”) and shall maintain and enforce its Code of Ethics for as long as this Agreement remains in effect. If it has not already done so, Sub-Adviser shall provide the Adviser and the Board with a copy of its Code of Ethics, together with evidence of its adoption by the Sub-Adviser. To the extent not covered by the Code of Ethics, the Sub-Adviser shall establish policies and procedures regarding the detection and prevention and the misuse of material, nonpublic information by the Sub-Adviser and its employees, and shall maintain and enforce such policies and procedures for as long as this Agreement remains in effect. On a quarterly basis, or more frequently as may be reasonably required by Adviser or the Board, Sub-Adviser shall certify to Adviser that Sub-Adviser has complied with the requirements of its Code of Ethics. For so long as this Agreement remains in effect, within forty-five (45) days of the end of the last calendar quarter of each year, and as otherwise requested by the Adviser or the Board, the Sub-Adviser shall certify to the Adviser that, during the previous year, there has been no material violation of the Code of Ethics or, if such a material violation has occurred, that appropriate action was taken in response to such violation. Upon the advance written request of the Adviser, the Sub-Adviser shall permit Adviser, its employees or its agents to examine the reports required to be made by the Sub-Adviser under the Code of Ethics and all other record relevant to the Code of Ethics.

To the extent the Sub-Adviser’s affiliates within the Macquarie Asset Management business division of Macquarie Group provide such services to the Funds, the Sub-Adviser will be responsible for all such services and the conduct of its affiliate with respect to the provision of such services to the same extent as if such services were provided directly by the Sub-Adviser.

Notwithstanding the foregoing, where the effect of a requirement of the 1940 Act reflected in any provision of this Agreement is revised or relaxed by a rule, regulation, interpretation or order of the SEC, whether of special or general application, such provision shall be deemed to incorporate the effect of such rule, regulation, interpretation or order.
