Dear Sir or Madam:

Harbor Capital Advisors, Inc. (the “Adviser”), a Delaware corporation, with its principal offices at 000 Xxxxx Xxxxxx Xxxxx, Xxxxxxx, Xxxxxxxx 00000, is the investment adviser to Harbor ETF Trust (the “Trust”) on behalf of Harbor Osmosis International Resource Efficient ETF (the “Fund”). The Trust has been organized as a statutory trust under the laws of the State of Delaware to engage in the business of an investment company. The Trust is an open-end, management investment company registered under the Investment Company Act of 1940, as amended (the “Investment Company Act”). The shares of beneficial interest of the Trust (the “Shares”) are divided into multiple series, including the Fund, as established pursuant to resolutions adopted by the Board of Trustees of the Trust (the “Board” or the “Trustees”). Pursuant to authority granted the Adviser by the Trust’s Trustees, the Adviser has selected Osmosis Investment Management US LLC (“you”, “your” or “yourself”) to act as a sub-investment adviser of the Fund and to provide certain other services, as more fully set forth herein (the “Agreement”). You are willing to act as such a sub-investment adviser and to perform such services under the Agreement. Accordingly, the Adviser and the Trust on behalf of the Fund agree with you as follows:

consistent with the investment objectives and policies of the Fund as set forth in the Fund’s Prospectus and Statement of Additional Information, as amended or supplemented, and any investment guidelines or other instructions received in writing from the Adviser. The Board or the Adviser may, from time to time, make additions to and withdrawals from the assets of the Fund allocated to you. You will determine what securities and other financial instruments shall be purchased for such portion of the Fund’s assets, what securities and other financial instruments shall be held or sold by such portions of the Fund’s assets, and what portion of such assets shall be held uninvested, subject always to the provisions of the Trust’s Declaration of Trust and By-Laws, and to the investment objectives, policies and restrictions of the Fund, as each of the same shall be from time to time in effect as set forth in the Fund’s Prospectus and Statement of Additional Information, as amended or supplemented, or any investment guidelines or other instructions received by you in writing from the Adviser, and subject, further, to such policies and instructions as the Board may from time to time establish and deliver to you. In accordance with paragraph 5, you or your agent shall arrange for the placing of all orders for the purchase and sale of portfolio securities with brokers or dealers selected by you for that portion of the Fund’s assets for which you serve as sub-investment adviser. You shall at no time have custody of the Fund’s assets and shall have no authority to deliver or pay securities or cash to yourself or any third party.

You shall have no responsibility for actions taken in reliance on the Declaration of Trust; the By-Laws; the Fund’s written investment objectives and policies; the Prospectus and Statement of Additional Information; and written instructions, each as in effect from time to time. You will conform your conduct to, and will ensure that your management of the portion of the Fund’s assets allocated to you complies with, the Investment Company Act and Investment Advisers Act of 1940, as amended (the “Investment Advisers Act”), and all rules and regulations thereunder, the requirements for qualification of the Fund as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), all other applicable federal and state laws and regulations, and with the provisions of the Fund’s Prospectus and Statement of Additional Information, as amended or supplemented, under the Securities Act of 1933, as amended, and the Investment Company Act.

The Board has delegated to you discretionary authority to exercise voting rights with respect to all proxies solicited by or with respect to the issuers of securities and other investments in the portion of the assets of the Fund managed by you. You shall be responsible for the administration of the proxy voting process and exercise these voting rights or refrain from voting in accordance with your then-current proxy voting policy, procedures and/or guidelines, as provided to us from time to time. You are authorized to instruct the Fund’s custodian as necessary in order for you to receive proxies and shareholder communications relating to securities held in the portion of the Fund’s assets managed by you. You will maintain appropriate records detailing your voting of proxies on behalf of the Fund and, upon the Adviser’s reasonable request, will provide a report setting forth the names of the issuers, proposals voted on, how the Fund’s shares were voted and your resolution of any conflicts of interest.

You shall maintain written compliance policies and procedures that are reasonably designed to ensure the Fund’s compliance with the foregoing and to prevent yourself and the Fund from violating applicable federal securities laws. You agree to provide the Trust and the Adviser with such reports and certifications and with such access to your officers and employees as the Trust

or Adviser may reasonably request for the purpose of assessing the adequacy of your compliance policies and procedures. You agree to notify the Adviser immediately upon detection of any breach of any of the Fund’s policies, guidelines or procedures and of any violation of any applicable law or regulation, including the Investment Company Act and Subchapter M of the Code, relating to that portion of the Fund’s assets allocated to you. You also agree to notify us promptly upon detection of any material violations of your compliance policies and procedures that relate to the Fund or your activities as an investment adviser generally, such as when the violation could be considered material to your advisory clients.

You shall keep the Fund’s books and records to be maintained by you and shall timely furnish to the Adviser all information relating to your services hereunder needed by the Adviser to keep other books and records of the Fund required by Rule 31a-1 under the Investment Company Act. You agree that all records which you maintain for the Fund are the property of the Fund and you shall surrender promptly upon request and without any charge to the Fund any of such records required to be maintained by you, provided that you may maintain a copy of such records as may be required under applicable law.

Upon reasonable request from the Adviser, you will reasonably assist the Valuation Committee of the Trust in valuing securities or other financial instruments of the Fund as may be required from time to time, including making available information of which you have knowledge related to the securities or other financial instruments being valued.

You shall promptly provide the Trust and the Adviser with any information you receive regarding class action claims or any other legal matters involving any security or other financial instrument held in the Fund and shall cooperate with the Trust and the Adviser to the extent necessary for the Trust or the Adviser to pursue and/or participate in any such action or matter. For the avoidance of doubt, subject to the preceding sentence, you will not be responsible for advising or taking any action on such legal actions.

Unless otherwise contemplated herein, in the performance of your duties hereunder, you are and shall be an independent contractor and unless otherwise expressly provided herein or otherwise authorized in writing, shall have no authority to act for or represent the Trust or the Fund in any way or otherwise be deemed to be an agent of the Trust or the Fund or of the Adviser. You will make your officers and employees available to meet with the Trustees and the Trust’s or Adviser’s officers at least quarterly on due notice to review the investments and investment program of the portion of the Fund’s assets allocated to you in light of current and prospective economic and market conditions. You will cooperate with the Trust’s independent public accountants and take all reasonable action in the performance of services and obligations under this Agreement to assure that the information needed by such accountants is made available to them for the expression of their opinion without any qualification as to the scope of their audit, including, but not limited to, their opinion included in the Trust’s annual report under the Investment Company Act and annual amendment to the Trust’s registration statement under the Investment Company Act.

Nothing in this Agreement shall limit or restrict the right of any of your directors, officers and employees to engage in any other business or to devote his or her time and attention in part to

DECEMBER 11, 2024

the management or other aspects of any business, whether of a similar or a dissimilar nature, nor limit or restrict your right to engage in any other business or to render service of any kind to any other corporation, firm, individual or association, except as specifically prescribed in paragraph 4 or as otherwise agreed upon in writing by you and the Adviser.

You may not delegate to any person, including to one or more companies that you control, are controlled by, or are under common control with, or to specified employees of any such companies, any of your investment subadvisory duties under this Agreement without the prior written consent of the Adviser.

3. Allocation of Charges and Expenses. You will bear your own costs of providing services hereunder. You will not be required to pay any expenses of the Fund, which include: (i) any Fund expenses payable by the Adviser under the Fund’s agreement with the Adviser (the “Adviser Agreement”); (ii) costs of borrowing money, including interest expenses; taxes and governmental fees; acquired fund fees and expenses; brokers’ commissions and any other transaction-related expenses and fees arising out of transactions effected on behalf of the Fund; and (iii) other ordinary expenses specified in the Adviser Agreement or disclosed in the Fund’s prospectus as payable by the Fund.

4. Compensation of the Subadviser. For all investment management services to be rendered hereunder, the Adviser will pay to you a fee, as set forth in Schedule A hereto, quarterly in arrears, based on a percentage of the average daily net assets (as defined below) of the portion of the Fund that you managed during the quarter. “Average daily net assets” means the average of the values placed on the net assets of the portion of the Fund that you managed on each day on which the net asset value of the Fund’s portfolio is determined. The net assets of the Fund are valued by the Fund’s custodian in the manner specified in the Fund’s Prospectus and Statement of Additional Information, as amended or supplemented. If determination of the value of net assets is suspended for any particular business day, then for the purposes of this paragraph 4, the value of the net assets of the Fund as last determined shall be deemed to be the value of the net assets. If the Fund’s custodian determines the value of the net assets of the Fund’s portfolio more than once on any day, the last such determination thereof on that day shall be deemed to be the sole determination thereof on that day for the purposes of this paragraph 4.

5. Avoidance of Inconsistent Position and Brokerage. In connection with purchases or sales of securities and other financial instruments for the account of the portion of the Fund allocated to you, neither you nor any of your directors, officers, employees or affiliates will act as a principal or agent or receive any compensation in connection with the purchase or sale of securities and other financial instruments by the Fund, other than the compensation provided for in this Agreement, except as permitted by the Investment Company Act and approved by the Board. You or your agent shall arrange for the placing of all orders for the purchase and sale of securities and other financial instruments for the portion of the Fund’s account allocated to you with brokers or dealers selected by you. In the selection of such brokers or dealers and the placing of such orders, you are directed at all times to seek for the Fund the most favorable execution and net price available. It is also understood that it is desirable for the Fund that you have access to supplemental investment and market research and security and economic analyses provided by

OSMOSIS INVESTMENT MANAGEMENT US LLC

HARBOR OSMOSIS INTERNATIONAL RESOURCE EFFICIENT ETF

DECEMBER 11, 2024

certain brokers who may execute brokerage transactions at a higher cost to the Fund than may result when allocating brokerage to other brokers on the basis of seeking the most favorable price and efficient execution. Therefore, you are authorized, consistent with the provisions of Section 28(e) of the Securities Exchange Act of 1934, to place orders for the purchase and sale of securities and other financial instruments for the Fund with such certain brokers if you determine, in good faith, that such commission is reasonable in relation to the value of the brokerage and/or research services provided by such broker-dealer, viewed in terms of either that particular transaction or your overall responsibilities with respect to the Fund, subject to review by the Board from time to time with respect to the extent and continuation of this practice. It is understood that the services provided by such brokers may be useful to you in connection with your services to other clients. If any occasion should arise in which you give any advice to clients of yours concerning the Shares of the Fund, you will act solely as investment counsel for such clients and not in any way on behalf of the Fund.

You will advise the Trust’s custodian on a prompt basis of each purchase and sale of a security and other financial instrument, specifying, if applicable, the name of the issuer, the description and amount or number of shares of the security purchased, the market price, gross or net price, trade date, settlement date and identity of the effecting broker or dealer and such other information as may be reasonably required. From time to time as the Board or the Adviser may request, you will furnish to the Trust’s officers and to each of its Trustees reports on portfolio transactions and reports on issues of securities and other financial instruments held in the portfolio, all in such detail as the Trust or the Adviser may reasonably request.

On occasions when you deem the purchase or sale of a security or other financial instrument to be in the best interest of the Fund as well as other of your clients, you, to the extent permitted by applicable laws and regulations, may, but shall be under no obligation to, aggregate the securities or other financial instruments to be sold or purchased in order to obtain the most favorable price or lower brokerage commissions and efficient execution. In such event, allocation of the securities or other financial instruments so purchased or sold, as well as the expenses incurred in the transaction, shall be made by you in the manner you consider to be the most equitable and consistent with your fiduciary obligations to the Fund and to such other clients.

To the extent you engage in block trades in futures and other derivatives, you agree to fulfill any relating notification requirements with respect to the Fund under applicable requirements of the Commodity Futures Trading Commission (“CFTC”).

6. Limitation of Liability of Subadviser. You shall not be liable for any loss suffered by the Adviser in connection with the matters to which this Agreement relates, except a loss resulting from willful misfeasance, bad faith or gross negligence on your part or from reckless disregard by you of your obligations and duties under this Agreement.

including a majority of the Trustees who are not interested persons of the Adviser or you or of the Trust.

10. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Illinois without regard to conflict of law principles and the Investment Company Act.

All persons dealing with the Trust or the Fund must look solely to the property of the Trust or the Fund for the enforcement of any claims against the Trust or the Fund as none of the Trustees, officers, agents or shareholders assume any personal liability for obligations entered into on behalf of the Trust or the Fund.

The captions in this Agreement are included for convenience of reference only and in no way define or delimit any of the provisions hereof or otherwise affect their construction or effect. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

You shall not use your knowledge of non-public information regarding the Fund’s portfolio as a basis to place or recommend any securities transactions for your own or your affiliates’ (or your respective directors, officers and employees) benefit to the detriment of the Fund. If you are requested or required by law to disclose any confidential information by any regulatory authority or pursuant to an order of a court or a facially valid administrative, legislative or other subpoena,

then you shall immediately notify the Adviser of the request to allow the Adviser the opportunity to legally contest or limit the scope and terms of any such disclosure required by law.

14. Use of Names. Neither party shall use the name, trademark or trade name of the other party or any of its affiliates or refer to the existence of this Agreement in any advertising, promotional or other material, whether in written, electronic or other form, distributed to any unaffiliated third party without obtaining specific prior written approval of the non-disclosing party.

Notwithstanding the foregoing, you agree that for so long as the Fund remains in existence and you serve as subadviser to the Fund, the Adviser shall have a non-exclusive, non-transferable, royalty-free license to reproduce, distribute, publicly display or otherwise use your name, including any short form thereof, logo or other identifying mark, and trade name (collectively, the “Licensed IP”) on its website and in advertising, promotional and marketing materials for the Harbor funds (collectively, “Materials”), subject to the terms of this paragraph 14.

The Adviser will be permitted to use the Licensed IP in any Materials solely for the purpose of identifying you as the subadviser to the Fund or including you in a listing of entities that serve as subadvisers to the series of the Harbor funds, without your prior approval. With respect to all other Materials, the Adviser’s use of the Licensed IP will be subject to your prior review and approval of a sample of such Materials, and you agree to use reasonable efforts to review such samples of Materials within five business days of their receipt. Following your review and approval of a sample of any Materials containing the Licensed IP, the Adviser will thereafter be permitted to modify such Materials (and use such modified Materials), without your approval, including, without limitation, in order to update statistical data or identifying information regarding any new or existing series or subadviser of the Harbor funds, provided that the modifications do not materially change the character or substance of the Materials. Notwithstanding anything to the contrary herein, the Adviser agrees that it will provide copies of any Materials containing the Licensed IP for review by you, from time to time, upon your reasonable request.

The Adviser agrees that it will not edit, excerpt or modify the Licensed IP in any way. The Adviser acknowledges that it will acquire no right, title or interest to the Licensed IP or any of the goodwill associated therewith. The Adviser further agrees that it will be responsible for ensuring that all Materials containing the Licensed IP which are used to market the Fund to current and prospective investors will comply with applicable laws, rules and regulations.

For the avoidance of doubt, you agree that “Osmosis” may appear in the Fund’s name so long as you continue to serve as subadviser to the Fund.

The agreement to the provisions of this Section 14 shall terminate automatically with respect to a Fund upon termination of this Agreement for the Fund. Advisor will cease the use of the Licensed IP in any newly printed Materials for the Fund (except as may be reasonably necessary to comply with applicable law or as required in connection with regulatory reporting in connection with the Fund) promptly upon termination of this Agreement.
