AMENDMENT NO. 1, EXTENSION AGREEMENT AND INCREMENTAL ASSUMPTION AGREEMENT dated as of June 9, 2023 (this “Amendment”), to the Second Amended and Restated Senior Secured Credit Agreement dated as of June 28, 2022 (as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Existing Credit Agreement”), by and among BLACKSTONE SECURED LENDING FUND, a Delaware statutory trust (the “Borrower”), each of the lenders party thereto (the “Existing Lenders”) and CITIBANK, N.A., as administrative agent (in such capacity, the “Administrative Agent”).

WHEREAS, the Borrower has requested that the Existing Credit Agreement be amended to effect an extension of the Maturity Date (the “Extension”), from June 28, 2027 (the “Existing Maturity Date”) to June 28, 2028 (the “Extended Maturity Date”) with respect to the Commitments and Loans of Existing Lenders consenting to such extension and make certain other modifications of the Existing Credit Agreement, in each case as set forth herein;

WHEREAS, the Borrower has requested in the letter, dated June 9, 2023 (the “Increase Request”), from the Borrower to the Administrative Agent that the aggregate amount of the Commitments be increased on the terms and subject to the conditions set forth herein;

NOW, THEREFORE, in consideration of the above premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Borrower, the Lenders party hereto and the Administrative Agent hereby agree as follows:

SECTION 1. Defined Terms. Capitalized terms used but not otherwise defined herein (including in the preliminary statements hereto) have the meanings assigned to them in the Existing Credit Agreement or the Amended Credit Agreement (as defined below), as the context requires.

SECTION 2. Extension of Maturity Date. (a) Each Person party hereto whose name is set forth on Schedule I hereto and has a commitment listed under the headings “2028 Revolving Dollar Commitments” or “2028 Revolving Multicurrency Commitments” (each such Person, a “2028 Revolving Lender”) has agreed to extend the existing maturity date of its Dollar Commitment (as defined in the Existing Credit Agreement) (the “2028 Revolving Dollar Commitments”) and/or its Multicurrency Commitment (as defined in the Existing Credit Agreement) (the “2028 Revolving Multicurrency Commitments”) (and in each case any Revolving Loans in respect thereof), as the case may be, in each case in the amount set forth opposite its name on such Schedule. The maturity date of the 2028 Revolving Dollar Commitments and 2028 Revolving Multicurrency Commitments shall be extended to the Extended Maturity Date.

(b) Each Person party hereto whose name is set forth on Schedule I hereto and has a Term Loan listed under the heading “2028 Term Loans” (each such Person, a “2028 Term Lender”, and, together with the 2028 Revolving Lenders, the “2028 Lenders”) has agreed to extend the maturity date of its Term Loans (the “2028 Term Loans”) in the amount set forth opposite its name on such Schedule. The maturity date of the 2028 Term Loans shall be extended to the Extended Maturity Date.

(c) The Existing Maturity Date shall remain applicable to the Commitments and Revolving Loans made by each Person whose name appears on Schedule I hereto and has a commitment listed under the headings “2027 Revolving Dollar Commitments” or “2027 Revolving Multicurrency Commitments” (each such Person, a “2027 Revolving Lender”), as the case may be.

(d) The Existing Maturity Date shall remain applicable to the Term Loans made by each Person whose name appears on Schedule I hereto and has a loan listed under the heading “2027 Term Loans” (each such Person, a “2027 Term Lender”, and together with the 2027 Revolving Lenders, the “2027 Lenders”).

SECTION 3. Commitment Increase; Confirmation of Increasing Lenders; Non-Pro Rata Decrease.

(a) Pursuant to Section 2.08(f) of the Amended Credit Agreement, each Person listed in Schedule II hereto (each, an “Increasing Lender” and together, the “Increasing Lenders”), hereby severally agrees to make Incremental Term Loans in the amount set forth opposite the name of such Increasing Lender listed in Schedule II hereto, as applicable, pursuant to the instruction of the Administrative Agent, such Loans to be effective as of the Amendment Effective Date (as defined below). The Incremental Term Commitments shall be subject to the same terms and conditions as the Initial Term Commitments, and the Incremental Term Loans shall be subject to the same terms and conditions as the Initial Term Loans and shall be treated as the same Class as the Initial Term Loans for purposes of the Amended Credit Agreement and the other Loan Documents (including, without limitation, under Section 2.10(d) of the Amended Credit Agreement). Each Increasing Lender with an Incremental Term Commitment agrees to make a Term Loan to the Borrower on the Amendment Effective Date in an aggregate principal amount (i) up to but not exceed such Increasing Lender’s Incremental Term Commitment listed on Schedule II hereto and (ii) that will not result in the total Covered Debt Amount exceeding the Borrowing Base as of the Amendment Effective Date.

(b) Each Increasing Lender (i) confirms that it has received a copy of the Amended Credit Agreement and the other Loan Documents, together with copies of the financial statements referred to therein and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into this Agreement; (ii) agrees that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own analysis and decisions in taking or not taking action under or based upon the Amended Credit Agreement and the other Loan Documents to which it is a party; and (iii) acknowledges and agrees that, from and after the Amendment Effective Date and subject to the conditions in clause (a) above, the Commitment Increase set forth opposite the name of the Increasing Lender listed in Schedule II hereto shall be included in the Commitment, and the Commitment Increase shall be governed for all purposes by the Amended Credit Agreement and the other Loan Documents.

2

(c) In connection with the foregoing increases, the existing Revolving Commitment of any Increasing Lender may, on the Amendment Effective Date, be reduced by an amount equal to the Commitment Increase of such Increasing Lender, as reflected on the Schedules attached hereto. On the Amendment Effective Date, the existing Revolving Lenders and the affected Increasing Lenders shall make and receive payments among themselves, in a manner determined by the Administrative Agent, so that, after giving effect thereto, the Revolving Loans of each Class are held ratably by the Revolving Lenders of such Class in accordance with the respective Revolving Commitments of such Class of such Revolving Lenders (after giving effect to the foregoing transactions). Concurrently therewith, the Revolving Lenders of such Class shall be deemed to have adjusted their participation interests in any outstanding Swingline Loans and Letters of Credit of such Class so that such interests are held ratably in accordance with their Revolving Commitments of such Class as so increased. Each of the Lenders party hereto consents to the foregoing transactions.

SECTION 4. Amendment of Existing Credit Agreement. Subject to the satisfaction of the conditions set forth in Section 6 below, effective as of the Amendment Effective Date (as defined below), (a) the Existing Credit Agreement (excluding, except as set forth below, all Schedules and Exhibits thereto) shall without further action be amended in its entirety in the form attached as Exhibit A hereto (the Existing Credit Agreement, as so amended, the “Amended Credit Agreement”) and (b) Schedules I, V and VI to the Existing Credit Agreement shall without further action be amended in their entirety in the forms attached as Schedule I and Schedule IV hereto.

SECTION 5. Representations and Warranties. The Borrower represents and warrants to the Lenders that:

(a) This Amendment has been duly executed and delivered by the Borrower and constitutes a legal, valid and binding obligation of the Borrower, enforceable in accordance with its terms, except as such enforceability may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws of general applicability affecting the enforcement of creditors’ rights and (ii) the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

(b) The representations and warranties of the Borrower set forth in the Amended Credit Agreement and in the other Loan Documents are true and correct in all material respects (or, in the case of any portion of the representations and warranties already subject to a materiality qualifier, true and correct in all respects) on and as of the Amendment Effective Date, or, as to any such representation or warranty that refers to a specific date, as of such specific date.

(c) As of the Amendment Effective Date, no Default or Event of Default has occurred and is continuing.

3
