Company. 
 “Comparable Treasury Issue” means the United States Treasury security selected by the Reference Treasury Dealer
as having a maturity comparable to the remaining term of the Notes to be redeemed (assuming the Notes matured on the applicable Par Call Date) that would be utilized, at the time of selection and in accordance with customary financing practice, in

each Holder describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase Notes on the payment date specified in
the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is
conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice. The Company shall comply with the requirements of Rule 14e-1 promulgated under the
Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. 

To the extent that the provisions of any securities laws or regulations conflict with this Section 13.01, the Company shall comply with
the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 13.01 by virtue of such conflict. 

On the Change of Control Repurchase Event payment date, subject to extension if necessary to comply with the provisions of the Investment
Company Act, the Company shall, to the extent lawful:

its offer;

properly tendered; and

Certificate stating the aggregate principal amount of Notes being purchased by the Company. 
 The Paying Agent will promptly remit to each
Holder of Notes properly tendered the purchase price for the Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of any
Notes surrendered; provided that each new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. 

If any Repayment Date upon a Change of Control Repurchase Event falls on a day that is not a Business Day, then the required payment will be
made on the next succeeding Business Day and no additional interest will accrue as a result of such delayed payment. 
 The Company will not
be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event if a third party makes an offer in respect of the Notes in the manner, at the time and otherwise in compliance with the requirements for an offer made by
the Company and such third party purchases all Notes properly tendered and not withdrawn under its offer.”

 Blackstone Secured Lending Fund 

2.750% Notes due 2026 
 This
Security is one of a duly authorized issue of Senior Securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of July 15, 2020 (herein called the
“Base Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and U.S. Bank National Association, as Trustee (herein called the “Trustee”, which term includes any
successor trustee under the Base Indenture), and reference is hereby made to the Base Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, and the
Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered, as amended and supplemented by the First Supplemental Indenture, dated as of July 15, 2020, by and between the Company and the
Trustee (herein called the “First Supplemental Indenture”), the Second Supplemental Indenture, dated as of October 23, 2020, by and between the Company and the Trustee (herein called the “Second Supplemental
Indenture”), and the Third Supplemental Indenture, relating to the Securities, by and between the Company and the Trustee (herein called the “Third Supplemental Indenture”; and the First Supplemental Indenture, the Second
Supplemental Indenture, the Third Supplemental Indenture and the Base Indenture collectively are herein called the “Indenture”). In the event of any conflict between the Base Indenture and the Third Supplemental Indenture, the Third
Supplemental Indenture shall govern and control. 
 This Security is one of the series designated on the face hereof, initially limited
in aggregate principal amount to $_______________. Under a Board Resolution, Officers’ Certificate pursuant to Board Resolutions or an indenture supplement, the Company may from time to time, without the consent of the Holders of Securities,
issue additional Securities of this series (in any such case “Additional Securities”) having the same ranking and the same interest rate, maturity and other terms as the Securities, provided that, if such Additional Securities are
not fungible with the Securities (or any other tranche of Additional Securities) for U.S. federal income tax purposes, then such Additional Securities will have different CUSIP numbers from the Securities represented hereby (and any such other
tranche of Additional Securities). Any Additional Securities and the existing Securities will constitute a single series under the Indenture and all references to the relevant Securities herein shall include the Additional Securities unless the
context otherwise requires. The aggregate amount of outstanding Securities represented hereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. 

The Securities of this series are subject to redemption in whole or in part at any time or from time to time, at the option of the Company, at
a Redemption Price per security equal to the greater of the following amounts, plus, in each case, accrued and unpaid interest and Additional Interest, if any, to, but excluding, the Redemption Date: 

 

	 	(A)	 100% of the principal amount of the Notes to be redeemed, or 



 

	 	(B)	 the sum of the present values of the remaining scheduled payments of principal and interest (exclusive of
accrued and unpaid interest and Additional Interest, if any, to the Redemption Date) on the Notes to be redeemed through the Par Call Date, discounted to the Redemption Date on a semi-annual basis (assuming a 360 day year consisting of twelve 30-day months) using the applicable Treasury Rate plus 50 basis points. 



Notwithstanding the foregoing, at any time on or after the Par Call Date, the Company may redeem some or all of the Notes, at any time, or
from time to time, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed plus, in each case, accrued and unpaid interest and Additional Interest, if any, to, but excluding, the Redemption Date. 

For purposes of calculating the Redemption Price in connection with the redemption of the Notes, on any Redemption Date, the following terms
have the meanings set forth below: 
 “Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal
to the semi-annual equivalent yield-to-maturity of the Comparable Treasury Issue (computed as of the third Business Day immediately preceding the redemption), assuming a
price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Redemption Price and the Treasury Rate will be determined by the Company. 

  
 A-4 













 “Comparable Treasury Issue” means the United States Treasury security
selected by the Reference Treasury Dealer as having a maturity comparable to the remaining term of the Notes to be redeemed (assuming the Notes matured on the applicable Par Call Date) that would be utilized, at the time of selection and in
accordance with customary financing practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes being redeemed. 

“Comparable Treasury Price” means (1) the average of the remaining Reference Treasury Dealer Quotations for the
Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Quotation Agent obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations. 

“Par Call Date” means August 16, 2026, which is the date that is one month prior to the maturity date of the Notes. 

“Quotation Agent” means a Reference Treasury Dealer selected by the Company. 

“Reference Treasury Dealer” means each of (1) Citigroup Global Markets Inc., (2) Goldman Sachs & Co. LLC,
(3) a primary U.S. government securities dealer selected by SMBC Nikko Securities America, Inc. and (4) a primary U.S. government securities dealer selected by the Company; provided, however, that if any of the foregoing or their
affiliates shall cease to be a primary U.S. government securities dealer in the United States (a “Primary Treasury Dealer”), the Company shall select another Primary Treasury Dealer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the
average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer
at 3:30 p.m. New York City time on the third Business Day preceding such Redemption Date. 
 All determinations made by any Reference
Treasury Dealer, including the Quotation Agent, with respect to determining the Redemption Price will be final and binding absent manifest error. 

Notice of redemption shall be given in writing and mailed, first-class postage prepaid or by overnight courier guaranteeing next-day delivery, to each Holder of the Securities to be redeemed, not less than fifteen (15) nor more than sixty (60) days prior to the Redemption Date, at the Holder’s address appearing in the
Security Register. All notices of redemption shall contain the information set forth in Section 11.04 of the Base Indenture. 
 Any
exercise of the Company’s option to redeem the Securities will be done in compliance with the Investment Company Act, to the extent applicable. 

If the Company elects to redeem only a portion of the Securities, the particular Securities to be redeemed will be selected in accordance with
the applicable procedures of the Trustee and, so long as the Securities are registered to the Depositary or its nominee, the Depositary. In the event of redemption of this Security in part only, a new Security or Securities of this series and of
like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a
Security not redeemed to less than $2,000. 
 Unless the Company defaults in payment of the Redemption Price, on and after the Redemption
Date, interest will cease to accrue on the Securities called for redemption. 
 Holders will have the right to require the Company to
repurchase their Securities upon the occurrence of a Change of Control Repurchase Event as set forth in the Indenture. 

  
 A-5 













 The Indenture contains provisions for defeasance at any time of the entire indebtedness of
this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture. 

If an Event of Default with respect to Securities of this series shall occur and be continuing (other than Events of Default related to
certain events of bankruptcy, insolvency or reorganization as set forth in the Indenture), the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. In the case of
certain events of bankruptcy, insolvency or reorganization described in the Indenture, 100% of the principal of and accrued and unpaid interest and Additional Interest on the Securities will automatically become due and payable. 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations
of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Security. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not
have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing
Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in
respect of such Event of Default as Trustee and offered the Trustee indemnity, security, or both, satisfactory to the Trustee, against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee shall not have
received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for sixty (60) days after
receipt of such notice, request and offer of indemnity and/or security. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on
or after the respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this Security or of the
