You will continue to work full-time until February 12, 2021 in your current position as Chief Financial Officer, reporting to Ali Dibadj, with the expectation that you will sign the Partnership’s 2020 annual report on Form 10-K, provided that it is filed on or before February 12, 2021. From February 13, 2021 until the Retirement Date, your title will be Senior Advisor and you will be available by phone upon reasonable request to address questions or provide historical context related to pertinent firm topics.

In addition, for year-end 2020, you shall be awarded total year-end compensation of no less than your 2019 total year-end incentive compensation award (the "Incentive Compensation"). The Incentive Compensation will be allocated in accordance with the cash/deferred formulas the firm uses as a whole. The deferred portion of the Incentive Compensation shall be awarded pursuant to the terms and conditions of the Incentive Compensation Award Program (''ICAP") provided you execute an ICAP Award Agreement (the "ICAP Agreement"). The cash portion of the Incentive Compensation, less applicable tax withholdings and other payroll deductions, shall be paid to you in the Company's second payroll in December of 2020.

The Compensation Committee has determined pursuant to the 2017 Plan (as that term is hereinafter defined) (1) to accelerate vesting of the Restricted Units in accordance with the provisions for acceleration of vesting upon termination without Cause set forth in the 2018 Award, and (2) that your election to defer payment of the Restricted Units to March 31, 2027 complies with the requirements of the 2017 Plan and is authorized by the Compensation Committee.

Within five (5) days after the Retirement Date, the Company Entities shall deliver to you a release that is substantially similar to the release contained in this paragraph 4(f).

5.Confidentiality. (a) As an employee of the Partnership, you have had access to confidential and proprietary information of the Partnership and/or its employees (the "Confidential Information"). You acknowledge and agree that the Confidential Information is confidential and proprietary to the Partnership and its employees and that disclosure or use of any of the Confidential Information would be detrimental to the Partnership and/or its clients. You agree that any and all Confidential Information shall be kept confidential and you further agree that you shall not furnish or disclose to any third party or use, directly or indirectly, for your own use or benefit or that of any other person or entity any Confidential Information of the Partnership, nor shall you attempt to access any Confidential Information. In the event that you are: (i) threatened or served with an action or motion to force disclosure of Confidential Information, or (ii) compelled to disclose Confidential Information by valid order of a court or

4

other government entity with the authority to compel the disclosure of such information, you will notify the Partnership in writing (unless such notification would violate applicable law), and as promptly as possible (and prior to making any disclosure if possible), in order to provide the Partnership the opportunity to intervene and object to, or seek restrictions on, the disclosure of such Confidential Information. If, nevertheless, the Confidential Information is ordered to be disclosed, you will furnish only that portion of the Confidential Information as directed by the Court. You will notify the Partnership immediately upon your discovery of any unauthorized use or disclosure of Confidential Information or any other breach of this paragraph. You agree to cooperate with the Partnership at its sole expense in every reasonable way to help the Partnership regain possession of such Confidential Information and prevent its further unauthorized use.

(b)Nothing in this Agreement prohibits you from reporting possible violations of law or regulation to any governmental agency or entity, or self-regulatory authority, including but not limited to the Department of Justice, the Securities and Exchange Commission, the Congress, and any agency Inspector General, or the Financial Industry Regulatory Authority (collectively, the "Regulators"),or from making other disclosures that are protected under the whistleblower provisions of state or federal law or regulation. You do not need the prior authorization of the Partnership to make any such reports or disclosures and you are not required to notify the Partnership that you have made such reports or disclosures. Further, nothing in this Agreement prohibits or restricts you (or your attorney) from filing a charge, responding to an inquiry, participating in an investigation, or providing testimony about this Agreement or its underlying facts and circumstances by, with, or before any Regulator. Nevertheless, you acknowledge and agree that by virtue of this Agreement you have waived any relief available to you (including without limitation, monetary damages, equitable relief and reinstatement) under any of the claims and/or causes of action waived in this Agreement. Therefore, you agree that you will not accept any award or settlement from any source or proceeding (including but not limited to any proceeding brought by any other person or by any government agency) with respect to any claim or right waived in this Agreement; provided, however, that nothing contained herein shall preclude you from receiving a monetary award from the Securities and Exchange Commission pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act, 15 U.S.C.

§ 78u-6.

6.Cooperation. The purpose of this paragraph is to effect a reasonable and orderly transition of your management responsibilities. Accordingly, until February 12, 2021, you shall (a) exercise care and direct oversight in your management duties and maintain normal business hours until such specific duties have been transitioned effectively and up to the reasonable communicated expectations of Ali Dibadj; (b) reasonably assist the Firm with the transition of your work responsibilities including but not limited to being available to attend internal meetings with Company personnel; and (c) be available to speak, or meet with, your staff and service providers as reasonably determined by Ali Dibadj.

From February 13, 2021 until the Retirement Date, you will not be expected

5

to be in the Company’s offices but will be available by phone upon reasonable request to address questions as provided in Section 1 above.

        You, the Company and the Partnership shall cooperate in good faith to prepare internal and external communication plans regarding your retirement. Any press release, Form 8K disclosure or other external statement, as well as any internal announcement regarding your retirement, whether written or verbal, shall be mutually agreed upon by you, the Company and Partnership.

In addition, you agree that you will reasonably assist and cooperate with the Company and the Partnership in connection with the defense or prosecution of any claim that may be made against or by the Company or the Partnership, or in connection with any ongoing of future investigation or dispute involving the Company or the Partnership, including preparing for testifying in any proceeding regarding pertinent knowledge you possess. The Company and Partnership agree to provide you with reasonable advance notice of any cooperation that will be required and will schedule any required cooperation to the maximum extent possible so as not to unreasonably interfere with your scheduled business, employment and personal activities. The Company will reimburse you for (or pay directly as incurred) all reasonable expenses incurred by you in connection with such assistance and cooperation obligations under this paragraph of Section 6, including your reasonably incurred legal fees and expenses if the parties hereto agree in good faith that, in providing such cooperation, it would be reasonable for you to retain counsel independent of the counsel for the Company and/or Partnership.

7.Partnership Property. No later than the Retirement Date, you shall return to the Partnership all documents, files and property belonging to the Partnership or the Company. For the avoidance of doubt, you may make and retain an electronic copy of your contacts list, calendar and any documents reasonably necessary in order for you to file your personal income tax returns.

8.This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors, heirs (in your case) and assigns. Any successor of the Company or the Partnership shall assume the obligations of the Company or the Partnership, as the case may be, under this Agreement and perform any duties and responsibilities in the same manner and to the same extent that the Company or the Partnership would be required to perform if no such succession had taken place.

9.Severability. If any provision of this Agreement is held by a court of competent jurisdiction to be illegal, void or unenforceable, such provision shall have no effect; however, the remaining provisions shall be enforced to the maximum extent possible. Further, if a court should determine that any portion of this Agreement is overbroad or unreasonable, such provision shall be given effect to the maximum extent possible by narrowing or enforcing in part that aspect of the provision found overbroad or unreasonable.

6

10.409A Compliance. The parties hereto intend that all benefits and payments to be made to you hereunder will be provided or paid to you in compliance with all applicable provisions of Section 409A of the Internal Revenue Code of 1986 as amended, and the regulations issued hereunder, and the rulings, notices, and other guidance issued by the Internal Revenue Service interpreting the same (the "Code"). If an amount is to be paid under this Agreement in two or more installments, each installment shall be treated as a separate payment for purposes of Section 409A.

11.Payment of Legal Fees.The Company and the Partnership agree that as additional consideration for you entering into this Agreement and your release hereunder, the Company, upon receipt of a customary invoice, will directly pay Fellig, Schwartz, LLC, on your behalf, for your reasonable attorneys’ fees incurred in connection with the negotiation and preparation of this Agreement up to a maximum of $20,000.

12.Board Membership.You may continue to serve on any non-profit board of directors of your choosing. From February 13, 2021 until the Retirement Date, you must request approval from AllianceBernstein to serve on the board of directors of any publicly traded company for which AllianceBernstein’s approval shall not be unreasonably withheld. Thereafter, there shall be no such restriction or approval requirement.

13.Entire Agreement. You shall continue to be bound by the post-termination restraints included in this Agreement and the ICAP Agreement for a termination without cause. For the avoidance of doubt, you will be bound by the employee non-solicit but not the non-compete provision of the ICAP Agreement. Except as expressly provided herein, effective as of the Retirement Date, all prior agreements relating to your employment by the Partnership and its affiliates will terminate and be of no further effect. This Agreement contains the entire understanding with respect to the subject matter hereof, and supersedes any and all prior agreements and understandings, whether written or oral, among you, the Company, the Partnership or any affiliate thereof with respect to the subject matter hereof. This Agreement may not be altered, modified or amended except by written instrument signed by you, the Company and the Partnership. This Agreement shall be governed by New York law, without reference to principles of conflicts of law. Jurisdiction and/or venue of any question involving the validity, interpretation or enforcement of this Agreement or any of its terms, provisions or obligations, or claims or breach thereof, shall exist exclusively in a court having subject matter jurisdiction located within the City and County of New York.

14.Counterpart Execution. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including PDF) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and to be an original signature for any and all purposes.
