AND

APOLLO INVESTMENT MANAGEMENT, L.P.

Fourth Amended and Restated Agreement made this 1st day of August 2022, by and between APOLLO INVESTMENT CORPORATION, a Maryland corporation (the “Corporation”), and APOLLO INVESTMENT MANAGEMENT L.P., a Delaware limited partnership (the “Adviser”).

WHEREAS, the Corporation is a closed-end management investment company that has elected to be treated as a business development company under the Investment Company Act of 1940 (the “Investment Company Act”);

WHEREAS, the Adviser is an investment adviser that has registered under the Investment Advisers Act of 1940 (the “Advisers Act”); and

WHEREAS, the Corporation desires to retain the Adviser to furnish investment advisory services to the Corporation on the terms and conditions hereinafter set forth, and the Adviser wishes to be retained to provide such services.

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the parties hereby agree as follows:

1. Duties of the Adviser.

(a) The Corporation hereby employs the Adviser to act as the investment adviser to the Corporation and to manage the investment and reinvestment of the assets of the Corporation, subject to the supervision of the Board of Directors of the Corporation, for the period and upon the terms herein set forth, (i) in accordance with the investment objective, policies and restrictions that are set forth in the Corporation’s Registration Statement on Form N-2, dated February 6, 2004, as the same shall be amended from time to time (as amended, the “Registration Statement”), (ii) in accordance with the Investment Company Act and (iii) during the term of this Agreement in accordance with all other applicable federal and state laws, rules and regulations, and the Corporation’s charter and by-laws. Without limiting the generality of the foregoing, the Adviser shall, during the term and subject to the provisions of this Agreement, (i) determine the composition of the portfolio of the Corporation, the nature and timing of the changes therein and the manner of implementing such changes; (ii) identify, evaluate and negotiate the structure of the investments made by the Corporation; (iii) close and monitor the Corporation’s investments; (iv) determine the securities and other assets that the Corporation will purchase, retain, or sell; (v) perform due diligence on prospective portfolio companies; and (vi) provide the Corporation with such other investment advisory, research and related services as the Corporation may, from time to time, reasonably require for the investment of its funds. The Adviser shall have the power

and authority on behalf of the Corporation to effectuate its investment decisions for the Corporation, including the execution and delivery of all documents relating to the Corporation’s investments and the placing of orders for other purchase or sale transactions on behalf of the Corporation. In the event that the Corporation determines to acquire debt financing, the Adviser will arrange for such financing on the Corporation’s behalf, subject to the oversight and approval of the Corporation’s Board of Directors. If it is necessary for the Adviser to make investments on behalf of the Corporation through a special purpose vehicle, the Adviser shall have authority to create or arrange for the creation of such special purpose vehicle and to make such investments through such special purpose vehicle in accordance with the Investment Company Act.

(b) The Adviser hereby accepts such employment and agrees during the term hereof to render the services described herein for the compensation provided herein.

(c) Subject to the requirements of the Investment Company Act, the Adviser is hereby authorized to enter into one or more sub-advisory agreements with other investment advisers (each, a “Sub-Adviser”) pursuant to which the Adviser may obtain the services of the Sub-Adviser(s) to assist the Adviser in fulfilling its responsibilities hereunder. Specifically, the Adviser may retain a Sub-Adviser to recommend specific securities or other investments based upon the Corporation’s investment objective and policies, and work, along with the Adviser, in structuring, negotiating, arranging or effecting the acquisition or disposition of such investments and monitoring investments on behalf of the Corporation, subject to the oversight of the Adviser and the Corporation. The Adviser, and not the Corporation, shall be responsible for any compensation payable to any Sub-Adviser. Any sub-advisory agreement entered into by the Adviser shall be in accordance with the requirements of the Investment Company Act and other applicable federal and state law.

(d) The Adviser shall for all purposes herein provided be deemed to be an independent contractor and, except as expressly provided or authorized herein, shall have no authority to act for or represent the Corporation in any way or otherwise be deemed an agent of the Corporation.

(e) The Adviser shall keep and preserve for the period required by the Investment Company Act any books and records relevant to the provision of its investment advisory services to the Corporation and shall specifically maintain all books and records with respect to the Corporation’s portfolio transactions and shall render to the Corporation’s Board of Directors such periodic and special reports as the Board may reasonably request. The Adviser agrees that all records that it maintains for the Corporation are the property of the Corporation and will surrender promptly to the Corporation any such records upon the Corporation’s request, provided that the Adviser may retain a copy of such records.

2. Corporation’s Responsibilities and Expenses Payable by the Corporation. All investment professionals of the Adviser and their respective staffs, when and to the extent engaged in providing investment advisory and management services hereunder, and the compensation and routine overhead expenses of such personnel allocable to such services, will be provided and paid for by the Adviser and not by the Corporation. The Corporation will bear all other costs and expenses of its operations and transactions, including (without limitation) those relating to: organization and offering; calculating the Corporation’s net asset value (including the cost and expenses of any independent valuation firm); expenses incurred by the Adviser payable to third

3. Compensation of the Adviser. The Corporation agrees to pay, and the Adviser agrees to accept, as compensation for the services provided by the Adviser hereunder, a base management fee (“Base Management Fee”) and an incentive fee (“Incentive Fee”) as hereinafter set forth. The Corporation shall make any payments due hereunder to the Adviser or to the Adviser’s designee as the Adviser may otherwise direct. To the extent permitted by applicable law, the Adviser may elect, or the Corporation may adopt a deferred compensation plan pursuant to which the Adviser may elect, to defer all or a portion of its fees hereunder for a specified period of time.

(a) Prior to January 1, 2023, the Base Management Fee shall be calculated initially at an annual rate of 1.50% (0.375% per quarter) of the lesser of (i) the average of the value of the Corporation’s gross assets (excluding cash or cash equivalents but including other assets purchased with borrowed amounts) at the end of each of the two most recently completed calendar quarters and (ii) the average monthly value (measured as of the last day of each month) of the Corporation’s gross assets (excluding cash or cash equivalents but including other assets purchased with borrowed amounts) during the most recently completed calendar quarter; provided, however, in each case, the Base Management Fee shall be calculated at an annual rate of 1.00% (0.250% per quarter) of the average of the value of the Corporation’s gross assets (excluding cash or cash equivalents but including other assets purchased with borrowed amounts) that exceeds the product of (A) 200% and (B) the value of the Corporation’s net asset value at the end of the prior calendar quarter. The Base Management Fee will be payable quarterly in arrears. The Base Management Fee for any partial quarter will be appropriately pro-rated. The value of the Corporation’s gross assets shall be calculated in accordance with the Corporation’s valuation policies.

3

(b) Prior to January 1, 2023, the Incentive Fee shall consist of two components that are independent of each other, with the result that one component may be payable even if the other is not. A portion of the Incentive Fee is based on the Corporation’s income (such fee referred to herein as the “Incentive Fee on Income”) and a portion is based on the Corporation’s capital gains (such fee referred to herein as the “Incentive Fee on Capital Gains”), each as described below.

(i) The Incentive Fee on Income will be determined and paid quarterly in arrears by calculating the amount by which (x) the aggregate amount of the “Pre-Incentive Fee Net Investment Income” (as defined below) in respect of the current calendar quarter and each of the eleven preceding calendar quarters beginning with the calendar quarter that commences on or after April 1, 2018, as the case may be (or the appropriate portion thereof in the case of any of the Corporation’s calendar quarters that commence January 1, 2019 and are one of the first eleven calendar quarters commencing on or after April 1, 2018) (in either case, the “Trailing Twelve Quarters”) exceeds (y) the Preferred Return Amount (as defined below) in respect of the Trailing Twelve Quarters. The Preferred Return Amount will be determined on a quarterly basis, and will be calculated by summing the amounts obtained by multiplying 1.75% by the Corporation’s net asset value at the beginning of each applicable calendar quarter comprising the relevant Trailing Twelve Quarters. The Preferred Return Amount will be calculated after making appropriate adjustments to the Corporation’s net asset value at the beginning of each applicable calendar quarter for Corporation capital issuances and distributions during the applicable calendar quarter. Subject to Section 3(b)(ii) below, the amount of the Incentive Fee on Income that will be paid to the Adviser for a particular quarter will equal the excess of the Incentive Fee on Income so calculated less the aggregate Incentive Fees on Income that were paid to the Adviser (excluding waivers, if any) in the preceding eleven calendar quarters (or portion thereof) comprising the relevant Trailing Twelve Quarters.

For this purpose, “Pre-Incentive Fee Net Investment Income” means interest income, dividend income and any other income (including, without limitation, any accrued income that the Corporation has not yet received in cash and any other fees such as commitment, origination, structuring, diligence and consulting fees or other fees that the Corporation receives from portfolio companies) (the “Ordinary Income”) accrued during the calendar quarter, minus the Corporation’s operating expenses accrued during the calendar quarter (including, without limitation, the Base Management Fee, administration expenses and any interest expense and dividends paid on any issued and outstanding preferred stock, but excluding the Incentive Fee on Income and the Incentive Fee on Capital Gains). For the avoidance of doubt, Pre-Incentive Fee Net Investment Income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation.

“Net Capital Loss” in respect of a particular period means the difference, if positive, between (i) aggregate capital losses, whether realized or unrealized, in such period and (ii) aggregate capital gains, whether realized or unrealized, in such period.

The calculation of the Incentive Fee on Income for each quarter is as follows:

4

(ii) The Incentive Fee on Income as calculated is subject to a cap (the “Incentive Fee Cap”). The Incentive Fee Cap in any quarter is an amount equal to (a) 20% of the Cumulative Pre-Incentive Fee Net Return (as defined below) during the relevant Trailing Twelve Quarters less (b) the aggregate Incentive Fees on Income that were paid to the Adviser (excluding waivers, if any) in the preceding eleven calendar quarters (or portion thereof) comprising the relevant Trailing Twelve Quarters. For this purpose, “Cumulative Pre-Incentive Fee Net Return” during the relevant Trailing Twelve Quarters means (x) Pre-Incentive Fee Net Investment Income in respect of the Trailing Twelve Quarters less (y) any Net Capital Loss in respect of the Trailing Twelve Quarters. If, in any quarter, the Incentive Fee Cap is zero or a negative value, the Corporation shall pay no Incentive Fee on Income to the Adviser in that quarter. If, in any quarter, the Incentive Fee Cap is a positive value but is less than the Incentive Fee on Income calculated in accordance with Section 3(b)(i) above, the Corporation shall pay the Adviser the Incentive Fee Cap for such quarter. If, in any quarter, the Incentive Fee Cap is equal to or greater than the Incentive Fee on Income calculated in accordance with Section 3(b)(i) above, the Corporation shall pay the Adviser the Incentive Fee on Income for such quarter.

(iii) The Incentive Fee on Capital Gains shall be determined and payable in arrears as of the end of each calendar year (or upon termination of this Agreement). This fee shall equal 20.0% of the sum of the Corporation’s realized capital gains on a cumulative basis, calculated as of the end of each calendar year (or upon termination of this Agreement), computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any Incentive Fees on Capital Gains previously paid to the Adviser. The aggregate unrealized capital depreciation of the Corporation shall be calculated as the sum of the differences, if negative, between (a) the valuation of each investment in the Corporation’s portfolio as of the applicable calculation date and (b) the accreted or amortized cost basis of such investment.

5

(c) Beginning on January 1, 2023, the Base Management Fee shall be calculated at an annual rate of 1.75% (0.4375% per quarter) of the Corporation’s net asset value as of the final business day of the prior calendar quarter; provided, however, that the Base Management Fee shall not be greater than 1.50% (0.375% per quarter) of the lesser of (i) the average of the value of the Corporation’s gross assets (excluding cash or cash equivalents but including other assets purchased with borrowed amounts) at the end of each of the two most recently completed calendar quarters and (ii) the average monthly value (measured as of the last day of each month) of the Corporation’s gross assets (excluding cash or cash equivalents but including other assets purchased with borrowed amounts) during the most recently completed calendar quarter. Net assets means the Corporation’s total assets less liabilities determined on a consolidated basis in accordance with accounting principles generally accepted in the United States of America. The Base Management Fee will be payable quarterly in arrears. The Base Management Fee for any partial quarter will be appropriately pro-rated. The value of the Corporation’s gross assets shall be calculated in accordance with the Corporation’s valuation policies.

(d) Beginning on January 1, 2023, the Incentive Fee shall consist of two components that are independent of each other, with the result that one component may be payable even if the other is not. A portion of the Incentive Fee is based on the Corporation’s income (such fee referred to herein as the “Incentive Fee on Income”) and a portion is based on the Corporation’s capital gains (such fee referred to herein as the “Incentive Fee on Capital Gains”), each as described below.

(i) The Incentive Fee on Income will be determined and paid quarterly in arrears by calculating the amount by which (x) the aggregate amount of the “Pre-Incentive Fee Net Investment Income” (as defined below) in respect of the current calendar quarter and each of the eleven preceding calendar quarters (in either case, the “Trailing Twelve Quarters”) exceeds (y) the Preferred Return Amount (as defined below) in respect of the Trailing Twelve Quarters; provided, however, that the Pre-Incentive Fee Net Investment Income in respect of the current calendar quarter exceeds the multiple of (A) 1.75% and (B) the Corporation’s net asset value at the beginning of such calendar quarter. For the purposes of the Incentive Fee calculations, each calendar quarter comprising the relevant Trailing Twelve Quarters that commenced prior to January 1, 2023 shall be known as a “Legacy Fee Quarter” while a calendar quarter that commenced on or after January 1, 2023 shall be known as a “Current Fee Quarter.” The Preferred Return Amount will be determined on a quarterly basis, and will be calculated by summing the amounts obtained by multiplying 1.75% by the Corporation’s net asset value at the beginning of each applicable calendar quarter comprising the relevant Trailing Twelve Quarters. The Preferred Return Amount will be calculated after making appropriate adjustments to the Corporation’s net asset value at the beginning of each applicable calendar quarter for Corporation capital issuances and distributions during the applicable calendar quarter. Subject to Section 3(d)(ii) below, the amount of the Incentive Fee on Income that will be paid to the Adviser for a particular quarter will equal the excess of the Incentive Fee on Income so calculated less the aggregate Incentive Fees on Income that were paid to the Adviser (excluding waivers, if any) in the preceding eleven calendar quarters (or portion thereof) comprising the relevant Trailing Twelve Quarters.

6

For this purpose, “Pre-Incentive Fee Net Investment Income” means interest income, dividend income and any other income (including, without limitation, any accrued income that the Corporation has not yet received in cash and any other fees such as commitment, origination, structuring, diligence and consulting fees or other fees that the Corporation receives from portfolio companies) (the “Ordinary Income”) accrued during the calendar quarter, minus the Corporation’s operating expenses accrued during the calendar quarter (including, without limitation, the Base Management Fee, administration expenses and any interest expense and dividends paid on any issued and outstanding preferred stock, but excluding the Incentive Fee on Income and the Incentive Fee on Capital Gains). For the avoidance of doubt, Pre-Incentive Fee Net Investment Income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation.

“Net Capital Loss” in respect of a particular period means the difference, if positive, between (i) aggregate capital losses, whether realized or unrealized, in such period and (ii) aggregate capital gains, whether realized or unrealized, in such period.

The calculation of the Incentive Fee on Income for each quarter is as follows:

(1) No Incentive Fee on Income shall be payable to the Adviser in any calendar quarter in which the Corporation’s Pre-Incentive Fee Net Investment Income for the Trailing Twelve Quarters does not exceed the Preferred Return Amount;

(2) 100% of the Corporation’s Pre-Incentive Fee Net Investment Income for the Trailing Twelve Quarters, if any, that exceeds the Preferred Return Amount but is less than or equal to an amount (the “Catch-Up Amount”), which shall be the sum of (i) the product of 2.1875% multiplied by the Corporation’s net asset value at the beginning of each applicable Legacy Fee Quarter included in the relevant Trailing Twelve Quarters and (ii) the product of 2.1212% multiplied by the Corporation’s net asset value at the beginning of each applicable Current Fee Quarter included in the relevant Trailing Twelve Quarters. The Catch-Up Amount is intended to provide the Adviser with an incentive fee of 20%, with respect to each Legacy Fee Quarter, and 17.50%, with respect to each Current Fee Quarter, on all of the Corporation’s Pre-Incentive Fee Net Investment Income when the Corporation’s Pre-Incentive Fee Net Investment Income reaches 2.1875% or 2.1212% per quarter, as applicable, (8.75% or 8.4848% annualized, respectively) during the Trailing Twelve Quarters; and

(3) For any quarter in which the Corporation’s Pre-Incentive Fee Net Investment Income for the Trailing Twelve Quarters exceeds the Catch-Up Amount, the Incentive Fee on Income shall equal 17.50% of the amount of the Corporation’s Pre-Incentive Fee Net Investment Income for such Trailing Twelve Quarters, as the Preferred Return Amount and Catch-Up Amount will have been achieved, provided, however, that the Incentive Fee on Income for any quarter shall not be greater than 17.50% of the amount of the Corporation’s current quarter’s Pre-Incentive Fee Net Investment Income.

7

(ii) The Incentive Fee on Income as calculated is subject to a cap (the “Incentive Fee Cap”). The Incentive Fee Cap in any quarter is an amount equal to (a) the sum of 20% of the Cumulative Pre-Incentive Fee Net Return (as defined below) during the relevant Legacy Fee Quarters included in the relevant Trailing Twelve Quarters and 17.50% of the Cumulative Pre-Incentive Fee Net Return during the relevant Current Fee Quarters included in the relevant Trailing Twelve Quarters less (b) the aggregate Incentive Fees on Income that were paid to the Adviser (excluding waivers, if any) in the preceding eleven calendar quarters (or portion thereof) comprising the relevant Trailing Twelve Quarters. For this purpose, “Cumulative Pre-Incentive Fee Net Return” during the relevant Trailing Twelve Quarters means (x) Pre-Incentive Fee Net Investment Income in respect of the Trailing Twelve Quarters less (y) any Net Capital Loss in respect of the Trailing Twelve Quarters. If, in any quarter, the Incentive Fee Cap is zero or a negative value, the Corporation shall pay no Incentive Fee on Income to the Adviser in that quarter. If, in any quarter, the Incentive Fee Cap is a positive value but is less than the Incentive Fee on Income calculated in accordance with Section 3(d)(i) above, the Corporation shall pay the Adviser the Incentive Fee Cap for such quarter. If, in any quarter, the Incentive Fee Cap is equal to or greater than the Incentive Fee on Income calculated in accordance with Section 3(d)(i) above, the Corporation shall pay the Adviser the Incentive Fee on Income for such quarter.

(iii) The Incentive Fee on Capital Gains shall be determined and payable in arrears as of the end of each calendar year (or upon termination of this Agreement). This fee shall equal 17.50% of the sum of the Corporation’s realized capital gains on a cumulative basis, calculated as of the end of each calendar year (or upon termination of this Agreement), computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any Incentive Fees on Capital Gains previously paid to the Adviser. The aggregate unrealized capital depreciation of the Corporation shall be calculated as the sum of the differences, if negative, between (a) the valuation of each investment in the Corporation’s portfolio as of the applicable calculation date and (b) the accreted or amortized cost basis of such investment.

4. Covenants of the Adviser. The Adviser covenants that it is registered as an investment adviser under the Advisers Act. The Adviser agrees that its activities will at all times be in compliance in all material respects with all applicable federal and state laws governing its operations and investments.

5. Excess Brokerage Commissions. The Adviser is hereby authorized, to the fullest extent now or hereafter permitted by law, to cause the Corporation to pay a member of a national securities exchange, broker or dealer an amount of commission for effecting a securities transaction in excess of the amount of commission another member of such exchange, broker or dealer would have charged for effecting that transaction, if the Adviser determines in good faith, taking into account such factors as price (including the applicable brokerage commission or dealer spread), size of order, difficulty of execution, and operational facilities of the firm and the firm’s risk and skill in positioning blocks of securities, that such amount of commission is reasonable in relation to the value of the brokerage and/or research services provided by such member, broker or dealer, viewed in terms of either that particular transaction or its overall responsibilities with respect to the Corporation’s portfolio, and constitutes the best net results for the Corporation.

8

6. Limitations on the Employment of the Adviser. The services of the Adviser to the Corporation are not exclusive, and the Adviser may engage in any other business or render similar or different services to others including, without limitation, the direct or indirect sponsorship or management of other investment based accounts or commingled pools of capital, however structured, having investment objectives similar to those of the Corporation, so long as its services to the Corporation hereunder are not impaired thereby, and nothing in this Agreement shall limit or restrict the right of any manager, partner, officer or employee of the Adviser to engage in any other business or to devote his or her time and attention in part to any other business, whether of a similar or dissimilar nature, or to receive any fees or compensation in connection therewith (including fees for serving as a director of, or providing consulting services to, one or more of the Corporation’s portfolio companies, subject to applicable law). So long as this Agreement or any extension, renewal or amendment remains in effect, the Adviser shall be the only investment adviser for the Corporation, subject to the Adviser’s right to enter into sub-advisory agreements. The Adviser assumes no responsibility under this Agreement other than to render the services called for hereunder. It is understood that directors, officers, employees and stockholders of the Corporation are or may become interested in the Adviser and its affiliates, as directors, officers, employees, partners, stockholders, members, managers or otherwise, and that the Adviser and directors, officers, employees, partners, stockholders, members and managers of the Adviser and its affiliates are or may become similarly interested in the Corporation as stockholders or otherwise.

7. Responsibility of Dual Directors, Officers and/or Employees. If any person who is a manager, partner, officer or employee of the Adviser or the Administrator is or becomes a director, officer and/or employee of the Corporation and acts as such in any business of the Corporation, then such manager, partner, officer and/or employee of the Adviser or the Administrator shall be deemed to be acting in such capacity solely for the Corporation, and not as a manager, partner, officer or employee of the Adviser or the Administrator or under the control or direction of the Adviser or the Administrator, even if paid by the Adviser or the Administrator.

8. Limitation of Liability of the Adviser; Indemnification. The Adviser (and its officers, managers, partners, agents, employees, controlling persons, members and any other person or entity affiliated with the Adviser, including without limitation its general partner and the Administrator) shall not be liable to the Corporation for any action taken or omitted to be taken by the Adviser in connection with the performance of any of its duties or obligations under this Agreement or otherwise as an investment adviser of the Corporation, except to the extent specified in Section 36(b) of the Investment Company Act concerning loss resulting from a breach of fiduciary duty (as the same is finally determined by judicial proceedings) with respect to the receipt of compensation for services, and the Corporation shall indemnify, defend and protect the Adviser (and its officers, managers, partners, agents, employees, controlling persons, members and any other person or entity affiliated with the Adviser, including without limitation its general partner and the Administrator, each of whom shall be deemed a third party beneficiary hereof) (collectively, the “Indemnified Parties”) and hold them harmless from and against all damages, liabilities, costs and expenses (including reasonable attorneys’ fees and amounts reasonably paid in settlement) incurred by the Indemnified Parties in or by reason of any pending, threatened or completed action, suit, investigation or other proceeding (including an action or suit by or in the right of the Corporation or its security holders) arising out of or otherwise based upon the performance of any of the Adviser’s duties or obligations under this Agreement or otherwise as an

9

investment adviser of the Corporation. Notwithstanding the preceding sentence of this Paragraph 8 to the contrary, nothing contained herein shall protect or be deemed to protect the Indemnified Parties against or entitle or be deemed to entitle the Indemnified Parties to indemnification in respect of, any liability to the Corporation or its security holders to which the Indemnified Parties would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of the Adviser’s duties or by reason of the reckless disregard of the Adviser’s duties and obligations under this Agreement (as the same shall be determined in accordance with the Investment Company Act and any interpretations or guidance by the Securities and Exchange Commission or its staff thereunder).

This Agreement may be terminated at any time, without the payment of any penalty, upon 60 days’ written notice, by the vote of a majority of the outstanding voting securities of the Corporation, or by the vote of the Corporation’s Directors or by the Adviser.

Further, notwithstanding the termination or expiration of this Agreement as aforesaid, the Adviser shall be entitled to any amounts owed under Section 3 through the date of termination or expiration and Section 8 shall continue in force and effect and apply to the Adviser and its representatives as and to the extent applicable.
