The Partnership Units granted pursuant to this Agreement represent interests in the profits of the Partnership and are being granted as additional consideration for services anticipated to be provided on or after the Grant Date to or for the benefit of the Partnership or an affiliate thereof (collectively, the “Employer”). Where the context permits, references to “the Employer” shall include the Employer and any successor to the Employer.

3. Capital Account Book-Up.

(a) Pursuant to Section 5.1.2 of the Partnership Agreement, Adjustment Amounts, if any, will be allocated as determined by the General Partner, including, if so determined by the General Partner, to the Partnership Units granted pursuant to this Agreement. For the avoidance of doubt, the General Partner may, but shall not be obligated to, prioritize such allocations to partnership interests in the Partnership that either (i) are not subject to performance conditions or (ii) are subject to performance conditions but for which the applicable performance conditions have already been achieved.

(b) Each Partnership Unit granted pursuant to this Agreement that has been allocated Adjustment Amounts in a sufficient amount such that the Partnership Unit has an Adjusted Capital Account per Partnership Unit equal to that of other Partnership Units not granted pursuant to this Agreement with the highest such Adjusted Capital Account per Partnership Unit, as certified by the compensation committee (or another committee composed entirely of independent directors who are “non-employee directors” for purposes of Rule 16b-3 under the Securities Exchange Act of 1934, as amended) of the board of directors of Moelis & Company (the “Compensation Committee”), shall be referred to herein as a “Booked-Up Partnership Unit.” Each Booked-Up Partnership Unit that has also become vested in accordance with this Agreement shall be referred to herein as a “Vested Booked-Up Partnership Unit.”

4. Rights as a Limited Partner; Redemption Rights; Repayment; Holdback.

(a) Except as provided in Sections 3(a), 4(b) and 4(c) hereof, the Participant shall have all of the rights of a Limited Partner as set forth in the Partnership Agreement with respect to the Partnership Units granted pursuant to this Agreement, including, without limitation, the right to receive Tax Liability distributions pursuant to Section 4.8 of the Partnership Agreement; provided that all of the terms and conditions contained in this Agreement and the Partnership Agreement shall apply to each of the Partnership Units granted pursuant to this Agreement and to any other securities distributed with respect to such Partnership Units. Each Partnership Unit granted pursuant to this Agreement shall remain subject to forfeiture to the Partnership as provided herein and in the Partnership Agreement.

(b) The Participant shall have no redemption or exchange rights with respect to all or any portion of the Partnership Units granted pursuant to this Agreement until the later of (i) the date that is at least two (2) years following the Grant Date and (ii) the date that the Partnership Units become Vested Booked-Up Partnership Units pursuant to Section 3(b) hereof. The Participant shall be eligible to receive payments under that certain tax receivable agreement, dated as of April 15, 2014 (as may be amended and/or restated from time to time), between the Partnership and certain other parties thereto in connection with any such redemption or exchange.

(c) The Participant shall be eligible to receive distributions of Available Cash pursuant to Section 4.2 of the Partnership Agreement pro rata in accordance with the Participant’s Percentage Interest represented by the Partnership Units granted pursuant to this Agreement as of the date on which the Partnership distributes such Available Cash; provided that:

(i) the Participant shall not be eligible to receive distributions of Available Cash under the Partnership Agreement unless and until all applicable vesting terms set forth in this Agreement have been achieved; and

(ii) if the amount of any distributions (in excess of any applicable tax distributions) payable to the Participant pursuant to Section 4.2 of the Partnership Agreement exceeds the Participant’s Adjusted Capital Account as of the applicable payment date, then the amount of such excess shall be not distributed to the Participant and shall instead be credited to a

2

holdback account maintain by the Partnership in respect of the Participant (such account, the “Holdback Account”). Any positive balance in the Holdback Account shall be paid to the Participant quarterly (as determined by the General Partner) in an amount equal to (but not in excess of) the positive balance of the Participant’s Adjusted Capital Account as of the applicable payment date, provided that the entire amount of any positive balance in the Holdback Account shall be paid to the Participant on the date of the Participant’s termination of service with the Employer for any reason.

5. Restrictive Covenants.

(a) The Participant acknowledges and agrees that the Participant is bound by certain restrictive covenants in connection with the Participant’s employment with the Employer and Section 10.15 of the Partnership Agreement, including, without limitation, non-competition, non-solicitation, confidentiality and non-disparagement covenants (as applicable, the “Restrictive Covenants”). The Restrictive Covenants are incorporated by reference as if fully set forth herein and are hereby re-executed and reaffirmed.

(b) Pursuant to 18 U.S.C. §1833(b), the Participant will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret of the Employer that (i) is made (A) in confidence to a federal, state, or local government official, either directly or indirectly, or to the Participant’s attorney, and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. If the Participant files a lawsuit for retaliation by the Employer for reporting a suspected violation of law, the Participant may disclose the trade secret to his attorney and use the trade secret information in the court proceeding, if the Participant (1) files any document containing the trade secret under seal, and (2) does not disclose the trade secret, except pursuant to court order. Nothing in this Agreement is intended to conflict with 18 U.S.C. §1833(b) or create liability for disclosures of trade secrets that are expressly allowed by such section. Further, nothing in any agreement that the Participant has with the Employer will prohibit or restrict the Participant from (i) voluntarily communicating with an attorney retained by the Participant, (ii) making any voluntary disclosure of information or documents related to any possible violation of law to any law enforcement agency, any governmental agency or legislative body, the Equal Employment Opportunity Commission, any self-regulatory organization or any state or local commission on human rights, in each case, without advance notice to the Employer, (iii) recovering an SEC whistleblower award as provided under Section 21F of the Securities Exchange Act of 1934, as amended, or (iv) disclosing any information (including confidential information) to a court or other administrative or legislative body in response to a subpoena, court order or written request (with advance notice to the Employer prior to any such disclosure to the extent legally permitted).

6. Effect of Forfeiture. Upon the forfeiture of any Partnership Units granted pursuant to this Agreement, the Participant (and the Participant’s heirs, transferees, successors and assigns) shall thereafter have no right, title or interest whatsoever in such forfeited Partnership Units and such forfeited Partnership Units shall be returned to the Partnership. The Participant (and the Participant’s heirs, transferees, successors and assigns) shall receive no payment from the Employer in connection with the forfeiture of any Partnership Units granted pursuant to this Agreement.

(b) The Participant qualifies as an Accredited Investor under the Securities Act.

(c) The Participant has such knowledge and experience in financial and business matters that he is capable of evaluating the merits and risks of the investment to be made by the Participant hereunder.

(f) The Participant acknowledges and agrees that (i) except as expressly provided for in this Agreement, no representations or warranties have been made to the Participant by the Employer or any other persons with respect to the Participant’s investment in the Partnership Units granted pursuant to this Agreement, (ii) except for this Agreement and the Partnership Agreement, there are no agreements, contracts, understandings or commitments between the Participant on the one hand and the Employer on the other hand, with respect to the Participant’s investment in the Partnership Units granted pursuant to this Agreement, (iii) in entering into this transaction the Participant is not relying upon any information, other than that contained in the Partnership Agreement, this Agreement and the results of the Participant’s own independent investigation, (iv) the Participant’s financial situation is such that the Participant can afford to hold the Partnership Units granted pursuant to this Agreement for an indefinite period of time, has adequate means for providing for the Participant’s current needs and personal contingencies, and can afford the eventuality that the Partnership Units may ultimately have no value, (v) the future value of the Partnership Units granted pursuant to this Agreement is speculative and (vi) the Participant is not entitled to any preemptive, tag-along, information or other minority investor rights with respect to the Partnership Units granted pursuant to this Agreement, other than as expressly set forth in this Agreement, the Partnership Agreement or as otherwise provided under applicable law.

(g) The Participant is fully informed and aware of the circumstances under which the Partnership Units granted pursuant to this Agreement must be held and the restrictions upon the resale of the Partnership Units under the Securities Act and any applicable state securities laws. The Participant understands that the Participant must bear the economic risk of the Participant’s investment in the Partnership Units granted pursuant to this Agreement for an indefinite period of time because the Partnership Units have not been registered under the Securities Act and, therefore, cannot be sold unless they are registered under the Securities Act and any applicable state securities laws or unless an exemption from such registration is available, (i) that the availability of an exemption may depend on factors over which the Participant has no control, and (iii) that unless so registered or exempt from registration, the Partnership Units may be required to be held for an indefinite period. The Participant understands that an exemption from registration is not presently available pursuant to Rule 144 promulgated under the Securities Act, that there is no assurance that such exemption will ever become available to the Participant, and that even if it were to become available, sales pursuant to Rule 144 would be limited in amount and could only be made in full compliance with the provisions of Rule 144.

(h) The Participant has received and reviewed the Partnership Agreement. The Participant acknowledges and agrees that the Partnership Units are subject to the provisions of the Partnership Agreement.

(i) The Participant has full authority to enter into this Agreement and the Partnership Agreement, and to perform the Participant’s obligations hereunder and thereunder. This Agreement and the Partnership Agreement have been duly and validly executed and delivered by the Participant and constitute legal, valid and binding obligations of the Participant, enforceable against the Participant in accordance with their terms, subject, as to the enforcement of remedies, to the effect of any applicable bankruptcy, insolvency, reorganization, moratorium or other similar law of general application affecting creditors and general principles of equity. The execution, delivery and performance of this Agreement and the Partnership Agreement does not and will not conflict with, violate or cause a breach of any agreement, contract or instrument to which the Participant is a party or any judgment, order, decree or law to which the Participant is subject.

(j) The Participant understands that the Employer’s decision to grant the Partnership Units to the Participant pursuant to this Agreement is predicated, in part, on the representations, warranties and covenants of the Participant contained herein.

9. Survival of Representations and Warranties; Indemnification. All representations and warranties of the Participant contained herein shall survive the execution of this Agreement and the grant of the Partnership Units contemplated hereby. The Participant agrees to indemnify and hold harmless the Employer from any actual liability, loss or expense (including, without limitation, reasonable attorneys’ fees) incurred by the Employer as a result of the Participant’s breach of any representation or warranty hereunder.

10. No Right of Continued Employment. Neither the grant of the Partnership Units hereunder nor anything contained in this Agreement shall confer upon the Participant any right to continue in the employ or service of the Employer, or to prohibit or restrict the Employer from terminating the Participant’s services at any time or for any reason whatsoever, with or without Cause, notwithstanding the effect any such action may have on the Participant, this Agreement, the Partnership Agreement or any Partnership Units that are or would otherwise be granted under this Agreement.

5

11. Mandatory 83(b) Election. The Participant acknowledges that the Participant is required to file an election under Section 83(b) of the Code in the form attached hereto as Exhibit B in accordance with the Partnership Agreement and that the filing of such election is the Participant’s responsibility. The Section 83(b) election form must be filed within thirty (30) days of the grant of the Partnership Units granted pursuant to this Agreement. The Participant further acknowledges that the Participant (and not the Employer or any of its agents) will be solely responsible for filing, and shall file, such form with the IRS, even if the Participant requests the Employer or its agents to make this filing on the Participant’s behalf and even if the Employer or its agents have previously made this filing on the Participant’s behalf. The Participant will promptly deliver a copy of such completed Section 83(b) election form to the Employer.

12. Tax Consequences. The Employer shall not be liable or responsible in any way for the tax consequences to the Participant relating to the grant, ownership, or vesting and related lapsing of any forfeiture conditions, of the Partnership Units granted pursuant to this Agreement. The Participant agrees to determine and be responsible for any and all tax consequences to the Participant related to the grant, ownership, or vesting and related lapsing of any forfeiture conditions, of the Partnership Units granted pursuant to this Agreement. By accepting the Partnership Units granted pursuant to this Agreement, the Participant acknowledges that the Partnership is treated as a partnership for federal and state income tax purposes and that the Participant will be treated as a partner for all purposes with respect to the Partnership Units. Accordingly, the Participant acknowledges that, among other things, the Participant will receive an annual Schedule K-1 from the Partnership requiring that the Participant report and pay tax on the Participant’s individual tax return the Participant’s distributive share of the Partnership’s income, gain, loss, deductions and credits, regardless of whether the Participant has received a distribution from the Partnership, and accordingly, the ownership of the Partnership Units may give rise to an out-of-pocket expense for the Participant. The Partnership has not made and will not make any statements or representations to the Participant concerning the federal, state and local tax consequences arising from the grant and holding of the Partnership Units contemplated by this Agreement and will have no obligation to indemnify or hold harmless the Participant for any claims or liabilities arising from such consequences. This Agreement is intended to be a part of the Partnership’s “partnership agreement,” as defined in Section 1.704-1(b)(2)(ii)(h) and 1.761-1(c) of the Treasury Regulations promulgated under the Code.

13. Notices. All notices to a party under this Agreement shall be provided in accordance with Section 10.9 of the Partnership Agreement. Any such notice may at any time be waived by the party entitled to receive such notice.

14. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and upon any person acquiring, whether by merger, consolidation, purchase of assets or otherwise, all or substantially all of the Employer’s assets and business, and, except as otherwise expressly provided herein, the parties’ respective heirs, executors, administrators, representatives, successors and permitted assigns. This Agreement may not be assigned, transferred or otherwise disposed of by the Participant, whether voluntarily or involuntarily, by operation of law or otherwise, without the prior written consent of the Employer except to the extent related to a Transfer of his Partnership Units granted pursuant to this Agreement to the extent permitted by, and in compliance with, this Agreement and the Partnership Agreement.

6

15. Complete Agreement. This Agreement and the Partnership Agreement contain the complete agreement among the parties hereto with respect to the Partnership Units granted pursuant to this Agreement and supersede all prior agreements and understandings among the parties hereto with respect thereto.

16. Severability. If any term or provision of this Agreement is held to be illegal, invalid or unenforceable under present or future laws effective during the term hereof, such provision shall be fully severable. This Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision has never comprised a part hereof, and the remaining provisions hereof shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance from this Agreement. In lieu of such illegal, invalid or unenforceable provisions, there shall be added automatically as a part hereof a provision as similar in terms and economic effect to such illegal, invalid or unenforceable provision as may be possible and be legal, valid and enforceable.

17. Waivers. No waiver of any provision of this Agreement is valid unless in writing and signed by the party against whom or which enforcement is sought, and any such waiver is effective only in the specific instance described and for the purpose for which the waiver was given. The failure of any party to this Agreement to insist upon or enforce strict performance by any other party to this Agreement of any provision of this Agreement shall not be construed as a waiver or relinquishment of such right or related remedy.

18. Set-Off. The Participant hereby acknowledges and agrees, without limiting rights of the Employer otherwise available at law or in equity, that, to the extent permitted by law, the number of Units under this Agreement (or the amount of any cash or property distributed with respect to or in lieu thereof) may be reduced by, and set-off against, any or all amounts or other consideration payable by the Participant to the Employer under any other agreement or arrangement between the Participant and the Employer; provided that any such set-off does not result in a penalty under Section 409A of the Code.

19. Clawback; Forfeiture Events.

(a) Notwithstanding any other provisions in this Agreement, the Partnership Agreement or the Plan, the Partnership Units granted hereunder will be subject to such deductions and clawback as may be required to be made pursuant to (i) any law, government regulation or stock exchange listing requirement that is applicable to Moelis & Company or any of its Affiliates or (ii) any clawback, forfeiture, recoupment or similar policy adopted by Moelis & Company, including, without limitation, the New York Stock Exchange-required Clawback Policy filed as Exhibit 10.24 to the Moelis & Company Form 10-K on February 22, 2024 (or any successor policy).

(b) In addition to the provisions set forth in Section 19(a) hereof, if there is a Forfeiture Event (as defined in the Plan), then the Compensation Committee of the Board of Directors of Moelis & Company (or its delegate pursuant to the Plan) may determine to forfeit all or a portion of any unvested Partnership Units hereunder. All determinations of whether any act or omission constitutes a Forfeiture Event and the amount of any forfeiture in any particular case will be made by the Compensation Committee of the Board of Directors of Moelis & Company (or its delegate pursuant to the Plan) in its sole discretion and will be final and binding on all parties.

[Signature Page to Performance-Based Vesting Agreement]

Exhibit A

EXHIBIT A

VESTING OF PARTNERSHIP UNITS

The Partnership Units granted pursuant to the Agreement shall be subject to vesting as set forth in this Exhibit A. Any capitalized term that is used, but not defined, in this Exhibit A shall have the meaning set forth in the Performance-Based Vesting Agreement to which it is attached (the “Agreement”).

1. Number of Partnership Units. The number of Partnership Units granted to the Participant under the Agreement shall be equal to 450,000 Partnership Units.

2. Normal Vesting. Except as otherwise provided in this Exhibit A, the Partnership Units granted pursuant to the Agreement shall vest (or partially vest as set forth below) upon the achievement of both the “Performance Condition” and the “Service Condition” (all as defined below).

(a) Performance Condition.

(i) The “Performance Condition” shall be deemed satisfied to the extent a share of Moelis & Company Class A common stock (the “Common Stock”) achieves the designated per share price targets set forth in the table below based on the volume weighted average closing share price of the Common Stock over any 20 consecutive trading-day period during the period beginning on the Grant Date and ending on the fifth anniversary of September 30, 2025 (the “Performance Period”), as reflected on the New York Stock Exchange or other such primary stock exchange in which the Common Stock is listed and traded (the “20-Day VWAP”). Achievement of any of the designated per share price targets set forth in the table below shall be certified by the Compensation Committee.

(ii) Notwithstanding the foregoing, if Moelis & Company pays any cash dividend on a share of Common Stock during the Performance Period (a “Qualifying Dividend”), the per share price of a share of Common Stock for purposes of determining the achievement of the Performance Condition shall be deemed to be adjusted to reflect any such Qualifying Dividend in a manner determined by the General Partner as if such Qualifying Dividends were reinvested in shares of Common Stock.

(iii) The number of Partnership Units granted pursuant to the Agreement for which the Performance Condition has been met (the “Earned Units”) will be determined (1) on a quarterly basis at the end of each fiscal quarter during the Performance Period, beginning on June 9, 2025, and (2) to the extent necessary, as of the final day of the Performance Period (the “End Date” and each such fiscal quarter end date together with the End Date, a “Measurement Date”), based on the highest 20-Day VWAP to have been achieved at any time starting on the Grant Date and ending on the applicable Measurement Date as follows:

If as of any Measurement Date, the highest 20-Day VWAP is between $86.00 and $144.00 per share and not exactly $115.00 per share, then the percentage of the total Partnership Units granted pursuant to the Agreement that will become Earned Partnership Units as of such Measurement Date be determined by linear interpolation between the amounts set forth in the table above.

(b) Service Condition.

(i) The “Service Condition” with respect to the Partnership Units that become Earned Units pursuant to Section 2(a) of this Exhibit A shall be deemed to be satisfied in equal installments with respect to such Earned Units on each of the third, fourth and fifth anniversaries of September 30, 2025 (each, a “Service Vesting Date”), in each case so long as the Participant remains in continuous employment with the Employer as Chief Executive Officer through, and has not given or received a notice of termination of such employment as of, the applicable Service Vesting Date; provided that if the applicable Service Vesting Date occurs prior to the date on which the applicable Partnership Units become Earned Units, then the corresponding number of Earned Units that would have vested as of such Service Vesting Date if the Partnership Units had become Earned Units prior to such Service Vesting Date shall fully vest immediately upon becoming Earned Units (the “Delayed Fully Vested Date”) so long as the Participant remains in continuous employment with the Employer as Chief Executive Officer through, and has not given or received a notice of termination of such employment as of, the Delayed Fully Vested Date.

(ii) [Intentionally Omitted.]

(iii) The Performance Condition shall apply to each installment of the Partnership Units subject to a Service Condition as if each such installment was an independent award. The following examples illustrate these principles:

(A) Assume that a 20-Day VWAP of $86.00 (taking into account reinvestment of Qualifying Dividends) was achieved as of the first quarter-end date following the second anniversary of the Grant Date, such that 150,000 Partnership Units become Earned Units as of such quarter-end date. Assume that no additional Partnership Units become Earned Units prior to the end of the Performance Period. Such 150,000 Earned Units shall become fully vested in equal installments on each of the third, fourth and fifth anniversaries of September 30, 2025.

A-2

(B) Assume the same facts as in the example in Section 2(b)(iii)(A), except that the 20-Day VWAP of $86.00 (taking into account reinvestment of Qualifying Dividends) was achieved as of the first quarter-end date following the third anniversary of September 30, 2025. In this case, a total of one-third of the Earned Units shall vest immediately upon the quarter-end date on which the Performance Units became Earned Units and the remaining 2/3 of such Earned Units shall vest in equal installments on the fourth and fifth anniversaries of September 30, 2025.

3. Change in Control. If a Change in Control occurs on or prior to the End Date and while the Partnership Units are outstanding, (i) the Performance Condition will be tested for any Partnership Units granted pursuant to the Agreement which are not Earned Units as of such Change in Control based on the price paid per share of Common Stock in the Change in Control transaction (and assuming reinvestment of Qualifying Dividends) and (ii) if the Participant is employed as of the date of the Change in Control, the Service Condition will be deemed to have been fully achieved as of the date of the Change in Control. Any Partnership Units that do not become fully vested as a result of the Change in Control shall immediately be forfeited.

4. Termination of Service. Notwithstanding anything set forth in this Exhibit A to the contrary:

(a) If the Participant’s service with the Employer in the role of Chief Executive Officer is terminated on or prior to the End Date by the Employer without Cause or by the Participant for Good Reason, then the Participant shall be eligible to vest in a number of Partnership Units equal to (1) the greater of (A) the number of Partnership Units that are Earned Units as of the date of notice of such termination (with the date of notice of termination treated as the End Date for purposes of this clause (A)), without regard to achievement of the Service Condition and (B) 225,000 Partnership Units that are already, or become, Earned Units based on the achievement of the Performance Condition relating to such Partnership Units during the Performance Period, without regard to the achievement of the Service Condition(the applicable number of Partnership Units in this clause (1), the “Termination Eligible Units”), less (2) the number of Partnership Units that otherwise fully vested on or prior to the date of notice of termination in accordance with Section 2 of this Exhibit A (as applicable, the “Qualifying Termination Units”). The Termination Eligible Units shall remain outstanding following the date of termination and shall vest on the same schedule as set forth in Section 2(b)(1) so long as (i) the Participant does not engage in Detrimental Activities at any time on or prior to the End Date and (ii) in the case of Termination Eligible Units set forth in subclause (1)(B) of this clause (a), the Performance Condition has been achieved during the Performance Period in accordance with Section 2(a) of this Exhibit A.

(b) If the Participant’s service with the Employer in the role of Chief Executive Officer terminates on or prior to the End Date as a result of the Participant’s death or Permanent Disability, then (i) the Service Condition will be deemed to have been fully achieved as of the date of such termination, (ii) any Partnership Units that are Earned Units as of the date of such termination shall fully vest as of the date of the such termination and (iii) any Partnership Units that are not yet Earned Units as of the date of such termination shall fully vest as of the applicable Measurement Date on which the Performance Condition is achieved during the Performance Period in accordance with Section 2(a) of this Exhibit A; provided, that in the event of a termination due to Permanent Disability, the Participant does not engage in Detrimental Activities at any time on or prior to the applicable Measurement Date.

A-3

(c) If the Participant’s service terminates for any other reason on or prior to the End Date (including, without limitation, (i) if the Participant’s service with the Employer is terminated on or prior to the End Date for Cause or (ii) if Participant’s service with the Employer is terminated on or prior to the End Date by the Participant without Good Reason (including any termination by the Participant in connection with Participant’s retirement)), then any Partnership Units granted pursuant to the Agreement that have not become fully vested shall immediately be forfeited.

5. Dividend Equivalents. Upon the payment of any Qualifying Dividend, the Participant shall receive an additional grant of Partnership Units with a value, as determined by the General Partner in its sole discretion, that is intended to replicate the value of the dividend that would have been paid to the Participant had the Partnership Units granted under the Agreement that are then-outstanding and unvested had instead been granted in the form of a number of shares of Common Stock equal to the total number of then-outstanding and unvested Partnership Units granted under the Agreement and subject to substantially the same terms and conditions as apply to the Partnership Units granted pursuant to the Agreement; provided, that (i) the per unit Target Value, the book-up mechanics set forth in Section 3(a) of the Agreement and the limitation on redemptions and exchanges set forth in Section 4(b) of the Agreement shall be calculated as of and shall run from the date of grant of such additional Partnership Units and (ii) the Participant shall make a new Section 83(b) election with respect thereto.
