SUB-ADVISORY AGREEMENT

This Agreement is made as of February 1, 2019, by and between Ohio National Investments, Inc., an Ohio corporation (the “Adviser”), and BlackRock Investment Management, LLC, a Delaware limited liability company (the “Sub-Adviser”).

WHEREAS, Ohio National Fund, Inc. (the “Fund”), is a Maryland corporation that is registered under the Investment Company Act of 1940, as amended, (together with the regulations promulgated pursuant thereto, the “1940 Act”); and

WHEREAS, the Adviser is a registered investment adviser under the Investment Advisers Act of 1940, as amended, (together with the regulations promulgated pursuant thereto, the “Advisers Act”); and

WHEREAS, the Adviser has been appointed as investment adviser to the Fund in accordance with the 1940 Act and the Advisers Act; and

WHEREAS, the Sub-Adviser is registered as an investment adviser under the Advisers Act and engages in the business of providing investment advisory services; and

WHEREAS, the Fund has authorized the Adviser to appoint the Sub-Adviser, subject to the requirements of the 1940 Act and the Advisers Act, as the sub-adviser with respect to the series of the Fund designated as the ON Bristol (the “Portfolio”) on the terms and conditions set forth below;

NOW, THEREFORE, IT IS HEREBY AGREED as follows:

SECTION 1.   Investment Advisory Services

(a) The Adviser hereby retains the Sub-Adviser, and the Sub-Adviser hereby accepts engagement by the Adviser, to supervise and manage on a fully-discretionary basis the cash, securities and other assets of the Portfolio that the Adviser shall from time to time place under the supervision of the Sub-Adviser (such cash, securities and other assets initially and as same shall thereafter be increased or decreased by the investment performance thereof and by additions thereto and withdrawals therefrom by the Adviser shall hereinafter be referred to as the “Portfolio”).

(b) All activities by the Sub-Adviser on behalf of the Adviser and the Portfolio shall be in accordance with the investment objectives, policies and restrictions set forth in the 1940 Act and in the Fund’s prospectus and statement of additional information, as amended from time to time (together, the “Prospectus”) and as interpreted from time to time by the Board of Directors of the Fund and by the Adviser (to the extent any such interpretations have been communicated to the Sub-Adviser in writing by the Fund or the Adviser). All activities of the Sub-Adviser on behalf of the Adviser and the Portfolio shall also be subject to the supervision and direction of the Adviser.

(c) In carrying out its obligations to manage the investments and reinvestments of the Portfolio, the Sub-Adviser shall:

1. obtain and evaluate pertinent economic, statistical, financial and other information affecting sectors and industries and the individual companies included in the Portfolio or under consideration for inclusion therein;

2. formulate and implement a continuous investment program for the Portfolio consistent with the investment objectives and related investment policies and restrictions for the Portfolio as set forth in the Prospectus;

3. take such steps as are necessary to implement the aforementioned investment program by placing orders for the purchase and sale of securities; and

4. coordinate with the Adviser to assure compliance with the Prospectus, qualification of the Portfolio as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”) and compliance with the diversification requirements of Section 817(h) of the Code. For the avoidance of doubt, the Adviser agrees and acknowledges that the Sub-Adviser is not the tax agent for the Fund or the Portfolio. The Sub-Adviser shall monitor the Portfolio pursuant to this subsection (4) based upon the books and records with respect to the Portfolio as provided by the Adviser or the Fund’s administrator, Custodian or other service providers. At or before the end of each calendar quarter, the Sub-Adviser shall notify the Adviser if the Sub-Adviser believes it has a reasonable basis for believing that the Portfolio has ceased to comply or might reasonably be expected to fail to comply with Subchapter M or Section 817(h) of the Code. Without limiting the preceding obligations of the Sub-Adviser, if the Adviser notifies the Sub-Adviser that the Adviser has determined, in its sole discretion, that the Portfolio has ceased to comply or might reasonably be expected to fail to comply with Subchapter M and Section 817(h) of the Code, the Sub-Adviser shall immediately take action to bring the Portfolio back into compliance within the applicable statutory cure period; provided, however that such action shall not, in and of itself, constitute an admission by the Sub-Adviser that the Portfolio is not in compliance with Subchapter M or Section 817(h) of the Code.

(d) The Sub-Adviser is authorized to enter into trading agreements and execute any documents (e.g., ISDAs, control agreements, clearing agreements and other trading arrangements on behalf of the Fund and/or Portfolio, as applicable) and take any other actions required to make investments pursuant to the Prospectus, which may include any market and/or industry standard documentation.

(e) In connection with the purchase and sale of securities of the Portfolio, the Sub-Adviser shall arrange for the transmission to the Adviser and the Fund’s custodian (the “Custodian”) on a daily basis such confirmation, trade tickets and other documents as may be necessary to enable them to perform their administrative responsibilities with respect to the Portfolio. In addition, the Sub-Adviser shall have authority to instruct the Custodian to (i) pay cash for securities and other property delivered to the Custodian for the Portfolio’s assets, (ii) deliver or accept delivery of, upon receipt of payment or payment upon receipt of, securities, commodities or other property underlying any futures or options contracts, and other property purchased or sold in the Portfolio and (iii) deposit margin or collateral which shall include the transfer of money, securities or other property to the extent necessary to meeting the obligations of the Portfolio with respect to any investments made pursuant to the Prospectus.

(f) In the event the Advisor or Custodian engages in securities lending activities with respect to the Portfolio, the Sub-Advisor will not be a party to or may not necessarily be aware of such lending activities. It is understood that the Sub-Advisor shall not be responsible for settlement delay or failure, corporate action failure or any related costs or loss due to such activities.

(g) Consistent with the Prospectus and subject to the supervision of Adviser, the Sub-Adviser shall have the sole and exclusive responsibility to select members of securities exchanges, brokers, dealers and futures commission merchants for the execution of transactions of the Portfolio and, when applicable,

2

shall negotiate commissions in connection therewith. In selecting brokers or dealers to execute transactions on behalf of the Portfolio, it shall be the policy of the Sub-Adviser to seek to obtain best execution and the Sub-Adviser agrees to act in conformance with its best execution policies and procedures. In assessing best execution, the Sub-Adviser will consider factors it deems relevant, which may include, without limitation, the breadth of the market in the security, the price of the security, the financial condition and execution capability of the broker or dealer and the reasonableness of the commission, if any, for the specific transaction and on a continuing basis. In selecting brokers or dealers to execute a particular transaction, and in evaluating best execution, the Sub-Adviser is authorized to consider the brokerage and research services (within the meaning of Section 28(e) of the Securities Exchange Act of 1934, as amended) provided to the Portfolio and/or other accounts (as defined herein) over which the Sub-Adviser exercises investment discretion.

(h) Subject to the Sub-Adviser’s obligations to seek to obtain best execution in selecting brokers or dealers to execute transactions on behalf of the Portfolio as set forth above, the Sub-Adviser may to the extent permitted by applicable laws and regulations, but shall be under no obligation to, aggregate orders. In such event, allocation of the orders, as well as the expenses incurred in the transaction, will be made by the Sub-Adviser in a fair and equitable manner and consistent with the Sub-Adviser’s fiduciary obligations to the Portfolio and to its other clients and in a manner consistent with the Sub-Adviser’s allocation policies and procedures. The Adviser recognizes that, in some cases, the Sub-Adviser’s allocation procedure may limit the size of the position that may be acquired or sold for the Portfolio.

(i) The Adviser acknowledges that (i) the Sub-Adviser is not the pricing agent for the Fund or the Portfolio, (b) the Sub-Adviser’s valuation policies may differ from the valuation policies of the Fund’s pricing agent and valuation committee and (c) therefore, the valuations made by the Portfolio may differ from the valuations made by or on behalf of the Sub-Adviser for other accounts that the Sub-Adviser manages. The Adviser further acknowledges that any certain information, data or analyses may be proprietary to the Sub-Adviser or otherwise consist of nonpublic information, agrees that nothing in this Agreement shall require Sub-Adviser to provide any information, data or analysis in contravention of applicable legal or contractual requirements, and, with respect to any information that is provided, agrees to use any such information only for the purpose of pricing Portfolio assets and to maintain their confidentiality.

(j) In connection with the placement of orders for the execution of the Portfolio’s securities transactions, the Sub-Adviser shall create and maintain all necessary records of the Portfolio as are required of an investment adviser of a registered investment company including, but not limited to, records required by the 1940 Act and the Advisers Act. All such records pertaining to the Portfolio shall be the property of the Fund and shall be available for inspection and use by the Securities and Exchange Commission (“SEC”), any other regulatory authority having jurisdiction, the Fund, the Adviser or any person retained by the Fund or the Adviser; provided that the Sub-Adviser may retain copies of any such records. 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. Notwithstanding the foregoing, Sub-Adviser has no responsibility for the maintenance of the records of the Fund, except for those related to the Sub-Adviser’s management of the Portfolio.

(k) As reasonably requested by the Adviser, the Sub-Adviser shall render such reports to the Adviser and/or to the Board of Directors of the Fund concerning the investment activity and composition of the Portfolio as a whole, in such form and at such intervals as the Adviser or the Board may from time to time reasonably require.

3

(l) The Sub-Adviser shall, for all purposes hereof, be an independent contractor and, except as expressly provided hereunder, shall have no authority to act for or represent the Fund or the Adviser in any way or otherwise be deemed an agent of the Fund or the Adviser.

SECTION 2.   Expenses

(a) The Sub-Adviser shall assume and pay all of its own costs and expenses, including those for furnishing such office space, office equipment, office personnel and office services as the Sub-Adviser may require in the performance of its duties under this Agreement.

(b) The Fund shall bear all expenses of the Portfolio’s organization and registration, and the Fund and Adviser shall bear all of their respective expenses of their operations and businesses not expressly assumed or agreed to be paid by the Sub-Adviser under this Agreement. In particular, but without limiting the generality of the foregoing, the Fund shall pay any fees due to the Adviser, all interest, taxes, governmental charges or duties, fees, brokerage and commissions of every kind arising hereunder or in connection herewith, expenses of transactions with shareholders of the Portfolio, expenses of offering interests in the Portfolio for sale, insurance, association membership dues, all charges of custodians (including fees as custodian and for keeping books, performing portfolio valuations and rendering other services to the Fund), independent auditors and legal counsel, fees paid to the Fund’s Board of Directors, SEC or other regulatory fees and state Blue Sky qualification fees, expenses of preparing, printing and distributing all prospectuses, proxy material, reports and notices to shareholders of the Fund, any extraordinary expenses and all other costs incident to the Portfolio’s existence.

SECTION 3.   Use of Services of Others

(a) Sub-Adviser may, as permitted by rule, regulation or position of the staff of the SEC, utilize the personnel of its affiliates including foreign affiliates in providing services under this Agreement, provided that Sub-Adviser remains solely responsible for the provision of services under this Agreement and provided further that such utilization shall not include any activity that could be construed as the provision of investment advice or that could be interpreted as causing the affiliate to be serving or acting as an investment adviser to the Portfolio. For the avoidance of doubt, delegation of services to affiliates under this Section 3(a) shall not relieve the Sub-Adviser of any obligations under this Agreement, including without limitation the indemnification obligations related to such services as provided under Section 5 hereunder.

(b) The Sub-Adviser may (at its expense) employ, retain or otherwise avail itself of the services or facilities of other persons or organizations for the purpose of providing the Sub-Adviser with such statistical or factual information, such advice regarding economic factors and trends or such other information, advice or assistance as the Sub-Adviser may deem necessary, appropriate or convenient for the discharge of the Sub-Adviser’s obligations hereunder or otherwise helpful to the Fund and the Portfolio.

SECTION 4.   Sub-Advisory Fees

The Adviser, or the Fund on behalf of the Adviser, will pay the Sub-Adviser the compensation specified in Appendix A. The Sub-Advisory Fees shall be payable solely by the Adviser, and the Fund shall not be liable to the Sub-Adviser for any unpaid Sub-Advisory Fees.

SECTION 5.   Limitation of Liability of Sub-Adviser; Indemnification

(a) The Sub-Adviser shall exercise its best judgment in rendering its services described in this Agreement. Except as may otherwise be required by the 1940 Act or the rules thereunder or other applicable law, or as otherwise provided in this Section 5, the Sub-Adviser 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 Sub-Adviser’s willful misfeasance, bad faith or gross negligence on its part in the performance of its duties, or reckless disregard by the Sub-Adviser of its obligations and duties, hereunder.

(b) The Adviser shall indemnify the Sub-Adviser and the Sub-Adviser’s affiliates, agents, controlling persons, directors, partners, officers, employees and shareholders (collectively, the “Sub-Adviser Indemnified Parties”) against, and hold such Sub-Adviser Indemnified Parties harmless from, any cost, expense, claim, loss, liability, judgment, fine, settlement or damage (including reasonable legal and other expenses) (collectively, “Losses”) arising out of any claim, demands, actions, suits or proceedings (civil, administrative or investigative) asserted or threatened to be asserted by any third party (collectively, “Proceedings”) in so far as such Loss (or actions with respect thereto) arises out of or is based upon (i) any material misstatement or omissions of a material fact in the Fund’s Prospectus, registration statement, proxy materials or reports filed with the SEC, unless and to the extent such material misstatement or omission was made in reliance upon, and is consistent with, information furnished in writing to the Adviser by any Sub-Adviser Indemnified Party for use therein or (ii) the Adviser’s willful misfeasance, bad faith or gross negligence in the performance of its duties hereunder or the Adviser’s reckless disregard of its obligations and duties under this Agreement.

(c) The Sub-Adviser shall indemnify the Fund, the Adviser and each of their respective affiliates, agents, controlling persons, directors, members of the Board, partners, officers, employees and shareholders (the “Adviser Indemnified Parties”) against, and hold them harmless from, any and all Losses arising out of any Proceedings in so far as such Loss (or actions with respect thereto) arises out of or is based upon (i) any material misstatement or omission of a material fact in information regarding the Sub-Adviser furnished in writing to the Adviser by the Sub-Adviser for use in the Fund’s Prospectus, registration statement, proxy materials or reports filed with the SEC or (ii) the Sub-Adviser’s willful misfeasance, bad faith or gross negligence in the performance of its duties hereunder or its reckless disregard of its duties under this Agreement, and nothing herein shall protect the Sub-Adviser against any such liability to the shareholders of the Fund or to the Adviser. Except as provided in the previous sentence, the Sub-Adviser shall not be liable to the Fund or to any shareholder of the Fund or to the Adviser for any claim or loss arising out of any investment or other act or omission in the performance of the Sub-Adviser’s duties under this Agreement, or for any loss or damage resulting from the imposition by any government of exchange control restrictions which might affect the liquidity of the Fund’s assets maintained with custodians or securities depositories in foreign countries, or from any political acts of any foreign governments to which such assets might be exposed, or for any tax of any kind (other than taxes on the Sub-Adviser’s income), including without limitation any statutory, governmental, state, provincial, regional, local or municipal imposition, duty, contribution or levy imposed by any government or governmental agency upon or with respect to such assets or income earned with respect thereto (collectively “Taxation”). Notwithstanding the foregoing sentence and the provisions of Section 5(d), the Sub-Adviser shall be liable for taxes or tax penalties incurred by the Portfolio, or by any legal or beneficial owner of the Portfolio’s shares, for any failure of the Portfolio to qualify as a regulated investment company under Subchapter M, or to meet the diversification requirements of Section 817(h) of the Code to the extent resulting from a material breach of the Sub-Adviser’s duties under this Agreement or any breach of its obligations under Section 1(c)(4). For clarity, the Sub-Adviser shall not be liable for other taxes or penalties incurred by the

5

Portfolio or its shareholders that are not attributable to the Sub-Adviser’s management of the Portfolio.

(d) In the event the Sub-Adviser is assessed any Taxation in respect of the assets, income or activities of the Portfolio, the Adviser and the Fund jointly and severally will indemnify the Sub-Adviser for all such amounts wherever imposed, together with all penalties, charges, costs and interest relating thereto and all expenditures, including reasonable attorney’s fees, incurred by the Sub-Adviser in connection with the defense or settlement of any such assessment. The Sub-Adviser shall undertake and control the defense or settlement of any such assessment, including the selection of counsel or other professional advisers, provided that the selection of such counsel and advisers and the settlement of any assessment shall be subject to the approval of the Adviser and the Fund, which approvals shall not be unreasonably withheld. The Adviser and the Fund shall have the right to retain separate counsel and assume the defense or settlement on behalf of the Adviser and the Fund, as the case may be, of any such assessment if representation of the Adviser and the Fund by counsel selected by the Sub-Adviser would be inappropriate due to actual or potential conflicts of interest.

SECTION 6.   Services to Other Clients and the Fund

(a) Subject to compliance with the 1940 Act, nothing contained in this Agreement shall be deemed to prohibit the Sub-Adviser or any of its affiliated persons from acting, and being separately compensated for acting, in one or more capacities on behalf of the Fund. The Adviser and the Fund understand that the Sub-Adviser may act as investment manager or in other capacities, whether similar or dissimilar in nature to the services hereunder, on behalf of other customers, which may include one or more private funds, entities registered under the 1940 Act and fiduciary or other managed accounts (collectively, “accounts”). It is understood and agreed that the directors, officers, and employees of the Sub-Adviser are not prohibited from engaging in any other business activity or from rendering services to any other person, or from serving as partners, officers, directors, trustees, or employees of any other firm or corporation, including other entities registered under the 1940 Act. In addition, it is understood that the persons employed by the Sub-Adviser to assist in the performance of the Sub-Adviser’s duties hereunder will not devote their full time to such services and nothing contained herein shall be deemed to limit or restrict the Sub-Adviser’s right or the right of any of the Sub-Adviser’s affiliates to engage in and devote time and attention to other businesses or to render services of whatever kind or nature.

(b) While information, recommendations and actions which the Sub-Adviser supplies to and does on behalf of the Portfolio shall in the Sub-Adviser’s judgment be appropriate under the circumstances in light of the investment objectives and policies of the Fund, as set forth in the Prospectus delivered to the Sub-Adviser from time to time, it is understood and agreed that they may be different from the information, recommendations and actions the Sub-Adviser or its affiliated persons supply to or do on behalf of the Sub-Adviser’s other accounts; provided that any such information, recommendations and actions supplied to and done on behalf of the Portfolio and to any other client is supplied in an impartial and fair manner and consistent with the Sub-Adviser’s fiduciary duties and obligations to the Portfolio. The Sub-Adviser agrees to use the same skill and care in providing services to the Portfolio as it uses in providing services to other similar accounts for which it has investment responsibility. As used herein, the term “affiliated person” shall have the meaning assigned to it in the 1940 Act.

SECTION 7.   Reports

(a) The Adviser shall timely furnish to the Sub-Adviser the Prospectus, proxy statements, reports and other information relating to the business and affairs of the Fund as the Sub-Adviser may reasonably require, and reasonably request, in order to discharge the Sub-Adviser’s duties under this Agreement.

For the avoidance of doubt, the parties may disclose such information to a limited number of employees, attorneys, accountants, affiliates, third party counterparties, Fund service providers and other advisers (collectively, “Representatives”) for which such disclosure is necessary for the performance of its responsibilities and duties hereunder. The foregoing shall not be applicable to any information (i) that is publicly available when provided or which thereafter becomes publicly available other than in contravention of this Section 9, (ii) known to such receiving party prior to disclosure to such party by the other party or its representatives and not otherwise subject to a separate confidentiality obligation, (iii) rightfully acquired by the receiving party from third parties whom the party
