Re: SUPERSEDING PROVISIONS

for

Plan Name: Cboe Global Markets Supplemental Retirement Plan

(a) Superseding Provision(s) – The following provisions supersede other provisions of this Adoption Agreement and/or the Basic Plan Document as described below:

1. Notwithstanding anything to the contrary in Section 1.03(a)(2), all Employees described in item 5 below are eligible to participate and shall be considered “Participants” in the Plan to the extent set forth in item 5.

2. Notwithstanding anything to the contrary in Section 1.04, for purposes of determining Deferral Contributions under the Plan, Compensation shall include only base compensation and bonuses (including amounts deferred by the Participant under the Chicago Board Options Exchange Deferred Compensation Plan for Officers). Compensation shall specifically exclude amounts contributed by the Employer under the Senior Executive Cafeteria Plan.

3. Notwithstanding anything to the contrary in Sections 1.05(a)(1) and 1.05(a)(2), Deferral Contributions shall be in whole and fractional percentages as designated by a Participant in his or her election form.

4. Section 1.05-Contributions. A Participant may elect to make deferral contributions, pursuant to § 1.05(a) of the Adoption Agreement in an amount or percentage of his or her Compensation for any Plan Year in excess of $230,000. Deferral contributions with respect to Compensation amounts below $230,000 may be made only under the Chicago Board Options Exchange Smart Plan. Notwithstanding anything to the contrary in Article 4.01, an election to defer Compensation shall continue in effect for Compensation relating to all services performed in succeeding calendar years until modified or revoked by the Participant with a subsequent election form pursuant to Article 4.

The Company will make a matching contribution to the Plan as set forth in § 1.05(b) of the Adoption Agreement based upon the amount of each Participant’s deferral contributions made under the Plan; provided that such matching contribution will be based only on the Participant’s deferral contributions that relate to his Compensation in excess of $230,000. Compensation for purposes of § 1.05 shall have the meaning set forth in § 1.04.

The $230,000 amounts referred to above shall all in cases be adjusted periodically to reflect cost of living increases at the same time and in the same manner as such amount is adjusted under Internal Revenue Code Section 401(a)(17), or any successor section.

5. Section 1.05(b)(2) - Matching Contributions. Notwithstanding the coverage requirements of Section 1.03(a) or the matching contribution described in Section 1.05(b) of the Adoption Agreement, the Employer shall make a matching contribution and/or a profit sharing contribution to the Plan for the Plan Year for any Employee (regardless of the amount of his or her Compensation for such Plan Year) who

Plan Number: 44316	ECM NQ 2007 AA
12/13/2022

elects to defer earnings otherwise payable to him or her in such Plan Year pursuant to the terms of the Chicago Board Option Exchange Deferred Compensation Plan for Officers, and as a result thereof receives a reduced matching contribution and/or a reduced profit sharing contribution for such Plan Year pursuant to the terms of the Chicago Board Options Exchange Smart Plan. The amount of the matching contribution and/or a profit sharing contribution made by the Employer to the Plan for a Participant pursuant to the terms of the preceding sentence shall equal the amount by which the matching contribution and/or profit sharing contribution made for him or her for the applicable Plan Year pursuant to the terms of the Chicago Board Options Exchange Smart Plan is reduced as a result of a deferral of earnings made pursuant to the terms of the Chicago Board Options Exchange Deferred Compensation Plan for Officers. A matching contribution and/or a profit sharing contribution made for a Participant pursuant to this paragraph shall be in addition to any matching contribution, if any, made for him or her for the applicable Plan Year pursuant to the Adoption Agreement.

6. If elected by the Participant on his or her initial election form, distribution of a Participant's entire interest in the Plan shall be made after the date of consummation of a Change in Control in accordance with Sections 1.07(a)(1)(G) and 1.07(c)(1); provided, however, that a Change in Control shall not include:

(a) any change in form of organization of the Employer from a non-stock entity to a stock corporation, or

(b) any public offering of the Employer's shares of stock after it becomes a stock corporation.

If the Participant fails to make an election, a Change in Control distribution shall not be made to the Participant.

7. Article 7.02 shall be replaced in its entirety with the following:

7.02. Death. If provided by the Employer in Section 1.08(e)(2), the Account of a Participant or former Participant who dies before the distribution of his entire Account will be 100% vested, provided that at the time of his death he is earning Years of Service.

Each Participant from time to time, pursuant to a beneficiary designation form furnished by the Employer, may designate any legal or natural person or persons (who may be designated contingently or successively) to whom his or her Plan interest is to be paid if he or she dies before receiving the entire balance thereof. A beneficiary designation shall be effective only when the executed beneficiary form is delivered to the Employer in writing or by other method prescribed by the Employer while the Participant is alive and will cancel all beneficiary designation forms delivered earlier. If a deceased Participant fails to designate a beneficiary prior to his or her death, or if all designated beneficiaries predecease the Participant, his or her interest in the Plan shall be paid to his or her surviving spouse, or if none, to his or her lawful descendants, per stirpes, or if none survive him or her, to the legally appointed representatives of his or her estate, or if none are appointed within six months after the date of his or her death, to his or her heirs at law.

8. Section 1.08(d) - Forfeiture. Notwithstanding the vesting schedules set forth in Sections 1.08(a) and (b), if the employment of any Participant, including the Chairman of the Board of Directors of the Employer, shall be terminated by the Employer for Cause, the Matching Contributions and Discretionary Employer Contributions credited to the Account of the Participant shall be forfeited,

Plan Number: 44316	ECM NQ 2007 AA
12/13/2022

and no amount shall be payable to or with respect to the Participant pursuant to the terms of the Plan. For purposes of this Section, Cause shall be deemed to exist if, and only if:

(a) A Participant shall engage, during the performance of his or her duties for the Employer, in acts or omissions constituting dishonesty, intentional breach of fiduciary obligation, or intentional wrongdoing or malfeasance;

(b) A Participant shall intentionally disobey or disregard a lawful and proper direction of the Board of Directors; or

(c) A Participant shall materially breach an employment agreement entered into between the Participant and the Employer and such breach by its nature is incapable of being cured, or such breach remains uncured for more than 30 days following receipt by the Participant of written notice from the Employer specifying the nature of the breach and demanding the cure thereof. For purposes of this clause (c), a material breach of any such employment agreement that involves inattention by the Participant to his or her duties under the employment agreement shall be deemed a breach capable of cure.

In addition, the Participant's employment shall be deemed to have terminated for Cause if, after the Participant's employment has terminated, facts and circumstances arising during the course of the Participant's employment are discovered that would have justified a termination for Cause.

The following shall not constitute Cause:

(a) Any personal or policy disagreement between a Participant and the Employer, or any member of the Employer or of the Board of Directors, or

(b) Any action taken by a Participant in connection with his or her duties for the Employer, or any failure to act, if the Participant acted or failed to act in good faith, and in a manner he or she reasonably believed to be in, and not opposed to, the best interest of the Employer, and he or she had no reasonable cause to believe his or her conduct was unlawful.

If the Matching Contributions and Discretionary Employer Contributions credited to the Account of a Participant shall be forfeited by reason of his or her termination of employment for Cause, the Employer shall give at least 30 days prior written notice to the Participant specifying in detail the reason or reasons constituting Cause.

9. In addition to the events indicated under Section 1.07(e), a Participant will be fully vested in his or her Account in the event of the termination of the Plan.

10. 8.01(e) Notwithstanding anything herein to the contrary, with respect to any Specified Employee, if the applicable payment trigger is Separation from Service, then payment shall not commence before the date that is six months after the date of Separation from Service (or, if earlier, the date of death or Disability of the Specified Employee, pursuant to Section 7.02 and 7.07). Payments to which a Specified Employee would otherwise be entitled during the first six months following the date of Separation from Service are delayed by six months.

11. 8.01(f) Article 8.01(f)(c) shall be replaced in its entirety with the following:

The Plan Sponsor shall pay the value of the entire Participant’s Balance in a single lump sum if the Participant’s entire Account Balance, including any Specific Date account balances, at Separation from Service if the balance is less than the Internal Revenue Code 402(g)(1)(B) limit ($22,500 in 2023). The single lump sum payment will be made at the time specified in Section 1.07(c)(1)
