Investment Advisory Agreement For Subadviser

(Harbor International Compounders ETF)

Dear Sir or Madam:

Harbor Capital Advisors, Inc. (the “Adviser”), a Delaware corporation, with its principal offices at 111 South Wacker Drive, Chicago, Illinois 60606, is the investment adviser to Harbor ETF Trust (the “Trust”) on behalf of Harbor International Compounders 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 C WorldWide Asset Management Fondsmaeglerselskab A/S (“you”, “your” or “yourself”) a limited liability company incorporated under Danish law and authorised as an investment firm by the Danish Financial Supervisory Authority, 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:

1. Delivery of Fund Documents. The Adviser has furnished you with copies, properly certified or authenticated, of each of the following:

(a) Agreement and Declaration of Trust of the Trust, as in effect on the date hereof (the “Declaration of Trust”);

(b) By-Laws of the Trust as in effect on the date hereof (the “By-Laws”); and

The Adviser will furnish you from time to time with copies of all material amendments of or supplements to the foregoing.

2. Advisory Services. You will regularly provide the Fund with advice concerning the investment management of that portion of the Fund’s assets that are allocated to you, which advice shall be 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 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 as applicable to you, 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 as applicable to you and relating to the services provided under this Agreement, 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 exercising these voting rights or refraining from voting in accordance with your then-current proxy voting policy, procedures and/or guidelines, as provided to us from time to time and based on the best interests of the Fund’s shareholders. 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. For the avoidance of doubt, you will not be responsible for filing Form N-PX or any other regulatory filings for the Fund in connection with your discretionary authority to the exercise of voting rights with respect to the Fund.

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 as soon as reasonably practicable 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 the Adviser as soon as reasonably practicable 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 the Fund or the Adviser.

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 as soon as reasonably practicable upon request and without any charge to the Fund any of such records required to be maintained by you. Notwithstanding the foregoing, you shall be entitled to maintain copies of such records as are required to be maintained by you under applicable law and/or pursuant to your compliance policies and procedures.

Upon reasonable request from the Adviser, you will reasonably assist the Valuation Committee of the Trust in valuing securities or other financial instruments of that portion of the Fund’s assets allocated to you 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 will not be responsible for determining or ratifying the valuations of the securities or other assets of the Fund that are used by the Fund for purposes of determining its net asset value (“NAV”) and assessing compliance with applicable laws and regulations and the Fund’s policies and procedures that depend on such valuations or NAV determinations.

You are not authorised to initiate or take part in class actions or in the settlement of class actions on behalf of the Fund involving any security or other financial instrument held in the Fund and shall not file any claim or take any action in relation to such class actions or settlements. You shall cooperate with the Trust and the Adviser to the extent necessary in relation to class action claims or any other legal matters involving any security or other financial instrument held in the Fund for the Trust or the Adviser to pursue and/or participate in any such action or matter.

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, which may be done virtually or by teleconference, 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 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 Schedule A.

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 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 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 and the Adviser as soon as reasonably practicable of each purchase and sale of a security and other financial instrument, specifying the name of the issuer, the description and amount or number of shares of the security purchased, the market price, commission and 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”).

Your Execution Policy and list of the key execution venues applied by you has been provided to the Adviser prior the execution of this Agreement. By entering into this Agreement, the Adviser has given its consent to the Execution Policy and the fact that you may execute orders outside a regulated market or multilateral trading facility.

6. Limitation of Liability of Subadviser. You shall not be liable for any error of judgment or mistake of law or for any loss suffered by the Fund or 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. You shall not be liable for consequential damage or other indirect losses.
