Each Installment Payment for any Installment Payment Period shall be computed on the basis of a 360-day year of twelve 30-day months. If an Installment Payment is payable for any period shorter than a full Installment Payment Period, such Installment Payment shall be computed on the basis of the actual number of days elapsed per 30-day month. Furthermore, if any date on which an Installment Payment is payable is not a Business Day, then payment of the Installment Payment on such date shall be made on the next succeeding day that is a Business Day, and without any interest or other payment in respect of any such delay. Installment Payments shall be paid to the Person in whose name the Note is registered, with limited exceptions as provided in the Indenture, at the close of business on the Business Day immediately preceding the related Installment Payment Date (each, a “Regular Record Date”). If the Notes do not remain in book-entry only form, the Company shall have the right to elect that each Regular Record Date shall be each February 1, May 1, August 1 and November 1 immediately preceding the relevant Installment Payment Date by giving advance written notice to the Trustee and the Holders. Installment Payments shall be payable (x) in the case of any Certificated Note, at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York; provided, however, that payment of Installment Payments may be made at the option of the Company by check mailed to the registered Holder at such address as shall appear in the Security register or (y) in the case of any Global Note, by wire transfer in immediately available funds to the account of the Depositary or its nominee or otherwise in accordance with applicable procedures of the Depositary.

BROOKDALE SENIOR LIVING INC.

10.25% Senior Amortizing Notes due 2025

This Note is one of a duly authorized series of Securities of the Company designated as its 10.25% Senior Amortizing Notes due 2025 (herein sometimes referred to as the “Notes”), issued under the Indenture, dated as of November 21, 2022, between the Company and American Stock Transfer & Trust Company, LLC, as trustee (the “Trustee,” which term includes any successor trustee under the Indenture) (including any provisions of the Trust Indenture Act that are deemed incorporated therein) (the “Base Indenture”), as supplemented by the First Supplemental Indenture, dated as of November 21, 2022 (the “Supplemental Indenture”), between the Company and the Trustee (the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”), to which Indenture reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders. The terms of other series of Securities issued under the Base Indenture may vary with respect to interest rates, issue dates, maturity, redemption, repayment, currency of payment and otherwise as provided in the Base Indenture. The Base Indenture further provides that securities of a single series may be issued at various times, with different maturity dates and may bear interest at different rates. This series of Securities is limited in aggregate initial principal amount as specified in the Supplemental Indenture.

Each Installment Payment shall constitute a payment of interest (at a rate of 10.25% per annum) and a partial repayment of principal on the Notes, allocated with respect to each Note as set forth in the schedule below:

The Notes shall not be subject to redemption at the option of the Company. However, a Holder shall have the right to require the Company to repurchase some or all of its Notes for cash at the Repurchase Price per Note and on the Repurchase Date, upon the occurrence of certain events and subject to the conditions set forth in the Indenture.

This Note is not entitled to the benefit of any sinking fund. The Indenture contains provisions for satisfaction and discharge, legal defeasance and covenant defeasance of this Note upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note.

If an Event of Default with respect to the Notes shall occur and be continuing, then (unless no declaration of acceleration or notice is required for such Event of Default) either the Trustee or the Holders of not less than 25% in principal amount of the Notes then outstanding may declare the aggregate principal amount of the Notes, and all interest accrued thereon, to be due and payable immediately, in the manner, subject to the conditions and with the effect provided in the Indenture.

A - 4

The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee, with the consent of the Holders of not less than a majority in principal amount of the Notes at the time outstanding, to execute supplemental indentures for certain purposes as described therein.

No provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the Repurchase Price, if applicable, of and all Installment Payments on this Note at the time, place and rate, and in the coin or currency, herein and in the Indenture prescribed.

The Notes are originally being issued as part of the 7.00% Tangible Equity Units (the “Units”) issued by the Company pursuant to that certain Purchase Contract Agreement, dated as of November 21, 2022, between the Company and American Stock Transfer & Trust Company, LLC, as Purchase Contract Agent, as Trustee and as attorney-in-fact for the holders of Purchase Contracts from time to time (the “Purchase Contract Agreement”). Holders of the Units have the right to separate such Units into their constituent parts, consisting of Separate Purchase Contracts (as defined in the Purchase Contract Agreement) and Separate Notes, during the times, and under the circumstances, described in the Purchase Contract Agreement. Following separation of any Unit into its constituent Separate Note and Separate Purchase Contract, the Separate Notes are transferable independently from the Separate Purchase Contracts. In addition, Separate Notes can be recombined with Separate Purchase Contracts to recreate Units, as provided for in the Purchase Contract Agreement. Reference is hereby made to the Purchase Contract Agreement for a more complete description of the terms thereof applicable to the Units.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the person in whose name this Note shall be registered upon the Security register for such series as the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of the principal of and, subject to the provisions of the Indenture, interest on such Note and for all other purposes; and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

The Notes are initially issued in registered, global form without coupons in denominations equal to $8.8996 initial principal amount and integral multiples in excess thereof.

No service charge shall be made to any holder for any registration of, transfer or exchange of the Notes, but the Company or the Trustee may require payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of the

Notes (other than any such transfer tax or similar governmental charge payable upon exchanges pursuant to Sections 2.7, 3.6 or 9.6 of the Base Indenture).

THIS NOTE SHALL BE DEEMED TO BE A CONTRACT UNDER THE LAWS OF THE STATE OF NEW YORK, AND FOR ALL PURPOSES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF SUCH STATE, INCLUDING, WITHOUT LIMITATION, SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW AND NEW YORK CIVIL PRACTICE LAWS AND RULES 327(b).

No recourse under or upon any obligation, covenant or agreement contained in the Indenture, or in any Note, or because of any indebtedness evidenced thereby, shall be had against any incorporator, as such, or against any past, present or future stockholder, officer or director, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Notes and the Installment Payments thereon by the Holders thereof and as part of the consideration for the issue of the Notes and the Installment Payments thereon.

Capitalized terms used but not defined in this Note shall have the meanings ascribed to such terms in the Indenture.

The Company and each Beneficial Holder agrees, for United States federal income tax purposes, to treat the Notes as indebtedness of the Company.
