FORM OF RESTRICTED STOCK UNITS AGREEMENT

Dear [Participant Name]:

Pursuant to the 2015 Employee Stock Plan (the “Plan”), you have been selected by the Compensation Committee of the Board of Directors (as more fully described in Section 11, the “Committee”) of Madison Square Garden Sports Corp. (the “Company”), effective as of [Date] (the “Grant Date”) to receive [#RSUs] restricted stock units (“Units”). The Units are granted subject to the terms and conditions set forth below and in the Plan.

Capitalized terms used but not defined in this agreement (this “Agreement”) have the meanings given to them in the Plan. The Units are subject to the terms and conditions set forth below:

1. Awards. Each Unit shall represent an unfunded, unsecured promise by the Company to deliver to you one share of the Company’s Class A Common Stock, par value $.01 per share (“Share”) on the Delivery Date. In accordance with Section 10(b) of the Plan, in the discretion of the Committee, in lieu of all or any portion of the Shares otherwise deliverable in respect of your Units, the Company may deliver a cash amount equal to the number of such Shares multiplied by the Fair Market Value of a Share on the date when Shares would otherwise have been issued, as determined by the Committee.

2. Vesting. One-third of your Units will vest on each of September 15, [year], [year] and [year] (each, a “Vesting Date”); provided that you have remained in the continuous employ of the MSG Entertainment Group, the Sphere Entertainment Group or the MSG Sports Group (each as defined below) through the applicable Vesting Date; provided further that fractional Units eligible to vest on each of the first two Vesting Dates will be rounded down to the nearest whole Unit. Subject to Sections 3 and 4, you will forfeit any unvested Units if you do not remain continuously employed with the MSG Entertainment Group, the Sphere Entertainment Group or the MSG Sports Group (each as defined below) from the Grant Date through any Vesting Date.

For purposes of this Agreement, the “MSG Sports Group” means the Company and any of its Subsidiaries. The “Sphere Entertainment Group” means Sphere Entertainment Co. (formerly known as Madison Square Garden Entertainment Corp.) (“Sphere Entertainment”) and any of its Subsidiaries. The “MSG Entertainment Group” means Madison Square Garden Entertainment Corp. (formerly known as MSGE Spinco, Inc.) (“MSG Entertainment”) and any of its Subsidiaries.

For purposes of this Agreement, if you are employed by the MSG Sports Group, your “Employer” means the Company; if you are employed by the Sphere Entertainment Group, your “Employer” means Sphere Entertainment; if you are employed by the MSG Entertainment Group, your “Employer” means MSG Entertainment; if you are employed by both the MSG Sports Group and the Sphere Entertainment Group, your “Employer” means Sphere Entertainment; if you are employed by both the MSG Entertainment Group and the MSG Sports Group, your “Employer” means MSG Entertainment; and if you are employed by each of the MSG Entertainment Group, the Sphere Entertainment Group and the MSG Sports Group, your “Employer” means MSG Entertainment.

3. Vesting in the Event of Death, Disability[, Retirement]¹ and Other Circumstances.

(A) If your employment is terminated as a result of your death, all of the unvested Units will vest as of the termination date.

(B) If your employment is terminated while you are Disabled, and Cause does not then exist, your unvested Units will immediately vest, and will become payable at such times as they would have otherwise vested pursuant to Section 2.

(C) [If your employment is terminated on or after the date that you achieve Retirement Eligibility, and Cause does not then exist, then so long as you enter into your Employer’s then-current form of separation agreement (which shall include, without limitation, a covenant not to compete), you will vest in your Units and such Units will become payable at such times as they would have otherwise vested pursuant to Section 2 regardless of whether or not you remain employed by your Employer on such dates; provided, however, that upon a termination for Cause, you will forfeit all Units that had not yet been paid.]²

(D) If your employment is terminated for other reasons, the Committee may, in its sole discretion determine to vest all or a portion of the unvested Units (but shall be under no obligation to consider doing so).

4. Change of Control/Going-Private Transaction. As set forth in Appendix 1 attached hereto, your entitlement to the Units may be affected in the event of a MSG Entertainment Change of Control, a Sphere Entertainment Change of Control, a MSG Sports Change of Control or a going-private transaction with respect to the Company, Sphere Entertainment or MSG Entertainment (each as defined in Appendix 1 attached hereto).

5. Transfer Restrictions. You may not transfer, assign, pledge or otherwise encumber the Units, other than to the extent provided in the Plan.

6. Right to Vote and Receive Dividends. You shall not be deemed to be the holder of, or have any of the rights of a stockholder with respect to, any Units unless and until the Company shall have issued and delivered Shares to you and your name shall have been entered as a stockholder of record on the books of the Company. Pursuant to Section 10(c) of the Plan, all ordinary (as determined by the Committee in its sole discretion) cash dividends that would have been paid upon any Shares underlying your Units had such Shares been issued will be retained by the Company for your account until your Units vest and such dividends will be paid to you (without interest) on the applicable Delivery Date to the extent that your Units vest.

7. Tax Representations and Tax Withholding. You hereby acknowledge that you have reviewed with your own tax advisors the federal, state and local tax consequences of receiving the Units. You hereby represent to the MSG Entertainment Group, the Sphere Entertainment Group and the MSG Sports Group that you are relying solely on such advisors and not on any statements or representations of the MSG Entertainment Group, the Sphere Entertainment Group or the MSG Sports Group, any of their respective Affiliates or any of their respective agents. If, in connection with the Units, your Employer is required to withhold any amounts by reason of any federal, state or local tax, such withholding shall be effected in accordance with Section 16 of the Plan. If your Units vest prior to payment in accordance with Section 3(B)[ or][,] (C)[ or (D)]⁴, then you agree to cooperate with your Employer to satisfy any tax withholding obligations, in such manner as determined by the Committee in its sole discretion.

8. Section 409A. It is the intent that payments under this Agreement shall comply with Section 409A of the Internal Revenue Code (“Section 409A”) to the extent applicable, and that the Agreement be administered accordingly. Notwithstanding anything to the contrary contained in this Agreement or any employment agreement you have entered into with your Employer, to the extent that any payment or benefit under this Agreement is determined by your Employer to constitute “non-qualified deferred compensation” subject to Section 409A and is payable to you by reason of termination of your employment, then (a) such payment or benefit shall be made or provided to you only upon a “separation from service” as defined for purposes of Section 409A under applicable regulations and (b) if you are a “specified employee” (within the meaning of Section 409A and as determined by your Employer), such payment or benefit shall not be made or provided before the date that is six (6) months after the date of your separation from service (or your earlier death). Each payment under this Agreement shall be treated as a separate payment under Section 409A.

9. Delivery. Subject to Sections 7, 10 and 13 and except as otherwise provided in this Agreement, the Shares will be delivered in respect of vested Units (if any) on the first to occur of the following events: (i) to you on or promptly after the applicable Vesting Date (but in no case more than fifteen (15) days after such date), (ii) in the event of your death to your estate after your death and during the calendar year in which your death occurs (or such later date as may be permitted under Section 409A) and (iii) in the event of any other termination of your employment (including pursuant to the provisions of Appendix 1) to you on the ninetieth (90th) day following termination of your employment (the “Delivery Date”). Unless otherwise determined by the Committee, delivery of the Shares at the Delivery Date will be by book-entry credit to an account in your name that the Company has established at a custody agent (the “custodian”). The Company’s transfer agent, EQ Shareowner Services, shall act as the custodian of the Shares; however, the Company may in its sole discretion appoint another custodian to replace EQ Shareowner Services. On the Delivery Date, if you have complied with your obligations under this Agreement and provided that your tax obligations with respect to the vested Units are appropriately satisfied, we will instruct the custodian to electronically transfer your Shares to a brokerage or other account on your behalf (or make such other arrangements for the delivery of the Shares to you as we reasonably determine).

10. Right of Offset. You hereby agree that the Company shall have the right to offset against its obligation to deliver shares of Class A Common Stock, cash or other property under this Agreement to the extent that it does not constitute “non-qualified deferred compensation” pursuant to Section 409A, any outstanding amounts of whatever nature that you then owe to the Company or any of its Subsidiaries.

11. The Committee. For purposes of this Agreement, the term “Committee” means the Compensation Committee of the Board of Directors of the Company or any replacement committee established under, and as more fully defined in, the Plan.

12. Committee Discretion. The Committee has full discretion with respect to any actions to be taken or determinations to be made in connection with this Agreement, and its determinations shall be final, binding and conclusive.

16. Entire Agreement. Except for any employment agreement between you and the MSG Entertainment Group, the Sphere Entertainment Group or the MSG Sports Group in effect as of the date of the grant hereof (as such employment agreement may be modified, renewed or replaced), this Agreement and the Plan constitute the entire understanding and agreement of you and the Company with respect to the Units covered hereby and supersede all prior understandings and agreements.
