Dear [Participant Name]:

Pursuant to MSG Sphere Corp.’s 2020 Employee Stock Plan or MSG Networks Inc.’s 2010 Employee Stock Plan, as amended, as applicable, on [Date] (the “Grant Date”), you were granted performance restricted stock units, each of which represents an unfunded, unsecured promise by MSG Sphere Corp. (formerly known as Madison Square Garden Entertainment Corp.) (“MSG Sphere”) to deliver to you one share of MSG Sphere Class A Common Stock. In conjunction with the spin-off of Madison Square Garden Entertainment Corp. (formerly known as MSGE Spinco, Inc.) (the “Company”) from MSG Sphere on [Date] (the “Distribution Date”), and pursuant to the Company’s 2023 Employee Stock Plan (the “Plan”), you are receiving the award described in this Performance Restricted Stock Units Agreement (the “Agreement”) of performance restricted stock units (the “Units”), each of which represents 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”).

Capitalized terms used but not defined in 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. In accordance with the terms of this Agreement, the target amount of your contingent Award is [#RSUs] restricted stock units (the “Target Award”), which number of units may be increased or decreased to the extent the performance criteria (the “Objectives”) set forth in Appendix 2 attached hereto have been attained in respect of the performance period set forth in Appendix 2 (the “Performance Period”). Each Unit shall represent an unfunded, unsecured promise by the Company to deliver to you one Share on the Delivery Date. The Award, calculated in accordance with Appendix 2 attached hereto, will vest upon the later of (i) September 15, [year] and (ii) the date on which the Compensation Committee of the Board of Directors (as more fully described in Section 12, the “Committee”) determines performance against the Objectives (the “Vesting Date”); provided, that you have remained in the continuous employ of the MSG Entertainment Group, the MSG Sphere Group or the MSG Sports Group (each as defined below) from the Grant Date through the Vesting 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 Award, 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. Subject to Sections 3 and 4, you will automatically forfeit all of your rights and interest in any unvested Units if you do not remain continuously employed with the MSG Entertainment Group, the MSG Sphere Group or the MSG Sports Group (each as defined below) from the Grant Date through the Vesting Date.

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

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

3.    Vesting in the Event of Death[or][,] Disability[, or Retirement].¹

(A)    If your employment is terminated as a result of your death on or prior to the Vesting Date, then the Target Award will vest as of the termination date. If, after June 30, [year] but prior to the Vesting Date, your employment is terminated as a result of your death, then your estate will receive the Award, if any, to which you would have been entitled on the Vesting Date had your employment not been so terminated.

(B)    If your employment is terminated while you are Disabled, and Cause does not then exist, the Award will remain subject to vesting on the Vesting Date in accordance with Section 1.

(C)    [If your employment is terminated on or after the date that you achieve Retirement Eligibility, and Cause does not then exist, and you enter into your Employer’s then-current form of separation agreement (which shall include, without limitation, a covenant not to compete), the Award will remain subject to vesting on the Vesting Date in accordance with Section 1.]²

(D)    For purposes of this Agreement:

4.    Change of Control/Going-Private Transaction. As set forth in Appendix 1 attached hereto, your entitlement to the Award may be affected in the event of a MSG Entertainment Change of Control, a MSG Sphere Change of Control, a MSG Sports Change of Control or a going-private transaction with respect to the Company, MSG Sphere or MSG Sports (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.    Unfunded Obligation. The Plan will at all times be unfunded and, except as set forth in Appendix 1 attached hereto, no provision will at any time be required to be made with respect to segregating any assets of the Company or any of its Subsidiaries for payment of any benefits under the Plan, including, without limitation, those covered by this Agreement. Your right or that of your estate to receive delivery or payment under this Agreement shall be an unsecured claim against the general assets of the Company, including any rabbi trust established pursuant to Appendix 1. Neither you nor your estate shall have any rights in or against any specific assets of the Company other than the assets held by the rabbi trust established pursuant to Appendix 1.

7.    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 Delivery Date to the extent that your Units vest.

8.    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 MSG Sphere 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 MSG Sphere 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)]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.

9.    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.

10.    Delivery. Subject to Sections 8, 11 and 14 and Appendix 1 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 Vesting Date (but in no case more than fifteen (15) days after such date) and (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) (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).

11.    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.
