Form of Performance Shares Award Agreement

This PERFORMANCE SHARES AWARD AGREEMENT (this “Agreement”) is made by and between Cowen Inc. (the “Company”), and (insert name) (the “Grantee”), effective March 1, 2022 (the “Grant Date”).

WHEREAS, the Company desires to grant to the Grantee an award of restricted stock units tied to certain performance measures described herein (the “Award”), subject to the terms of the Cowen Inc. 2020 Equity and Incentive Plan, as amended in 2021 (the “Plan”);

WHEREAS, the Award shall consist of a grant of restricted stock units (the “RSUs”) in accordance with the terms and subject to the vesting conditions set forth in this Agreement and the Plan; and

WHEREAS, the capitalized terms used but not defined herein shall have the respective meanings given to them in the Plan.

NOW, THEREFORE, it is agreed as follows:

Pursuant to the terms and conditions and restrictions of this Agreement and the Plan, the Award granted to the Grantee by the Company as of the Grant Date consists of a target award of (insert amount) (insert amount) RSUs (the “Target RSUs”).

The actual number of RSUs that become vested and settled (each, an “Attained RSU”) shall be based on the attainment of the performance metrics (the “Performance Metrics”) provided in, and calculated under, Section 1.2.

Each RSU constitutes an unfunded and unsecured promise of the Company to deliver (or cause to be delivered) to the Grantee upon settlement, subject to the terms of this Agreement, one share of Stock. Until such settlement and delivery, the Grantee has only the rights of a general unsecured creditor, and no rights as a shareholder of the Company, provided that, whenever a normal cash dividend is paid on shares of Stock, the Company shall credit to the Grantee an amount of cash equal to the product of the per-share amount of the dividend paid multiplied by the number of Attained RSUs as of the applicable Vesting Date (the “Dividend Equivalent Amount”). Such credited amounts shall be paid to the Grantee when and only to the extent the Stock underlying an Attained RSU is transferred to the Grantee in accordance with Section 1.2 below.

(a)Normal Vesting and Settlement Schedule. The Grantee shall become vested in the Target RSUs upon December 31, 2024 (the “Vesting Date”), subject to the calculation of the Performance Metrics with respect to the three-year performance period of calendar years 2022, 2023, and 2024 (the “Performance Period”).

Vesting on the Vesting Date shall be conditioned on the following: (1) the Grantee remains actively employed by the Company as of the Vesting Date; or (2) as otherwise provided in Section 1.2(c), 1.2(d) and 1.2(e). The Attained RSUs will be settled as follows: (i) any Attained RSUs up to a Payout Rate (defined below) of one hundred and twenty percent (120%) will be settled in Cowen Inc. stock on March 10, 2025 (the “Settlement Date”); and (ii) any Attained RSUs above a Payout Rate of one hundred and twenty percent (120%) will be settled in undeferred cash via payroll on March 31, 2025, with the value of an Attained RSU calculated based on the volume weighted average price of Cowen Inc. stock on the Settlement Date. For the avoidance of doubt, the calculation of the Attained RSUs will be performed after the Vesting Date, but no later than the Settlement Date, once data necessary to analyze the Performance Metrics becomes available for the full Performance Period.

(b)Performance Metrics Calculation. With respect to the Target RSUs, the number of Attained RSUs shall be determined in accordance with this Section 1.2(b).

With respect to the Performance Period, as of the Vesting Date, the number of Preliminary RSUs shall be equal to the product of the Target RSUs and the applicable percentage in the table below (the “Payout Rate”) based on the Company’s AROCE (as defined in Section 2.1) with respect to the Performance Period.

* Performance between the Threshold and the Maximum will be interpolated

The number of Attained RSUs shall be equal to the product of (A) the Preliminary RSUs and (B) the applicable Modifier indicated in the table below determined based on the Company’s TSR (as defined in Section 2.1) during such Performance Period versus the TSR of the companies comprising the S&P SmallCap 600 Financial Sector Index (the “Index”) as of the first day of each Performance Period for the same period:

* The relative TSR will be interpolated between the 25th percentile and below and the 75th percentile. The relative TSR position will be calculated using the following formula where N is the total number of companies in the Index including Cowen and R is Cowen’s ranking compared to the Index: N-R / N-1

(i)The companies comprising the Index may be changed with respect to any Performance Period as follows:

(1)In the event of a merger, acquisition or business combination transaction of a company included in the Index (an “Index Company”) with or by another Index Company, the surviving entity shall remain a company included in the Index and the company that did not survive will be excluded from the Index.

(2)In the event of a merger of an Index Company with an entity that is not a company included in the Index (a “Non-Index Company”), or the acquisition or business combination transaction by or with an Index Company, or with a Non-Index Company, in each case where the Index Company is the surviving entity and remains publicly traded, the surviving entity shall remain a company included in the Index.

(3)In the event of a merger or acquisition or business combination transaction of an Index Company, by or with a Non-Index Company, a “going private” transaction involving an Index Company or the liquidation of an Index Company, where the Index Company is not the surviving entity or is otherwise no longer publicly traded, the company will be excluded from the Index.

(4)In the event of a bankruptcy of an Index Company, such company shall remain included in the Index and will have an assigned TSR of -100%.

(5)In the event of a stock distribution from an Index Company consisting of the shares of a new publicly-traded company (a “spin-off”), if, following such stock distribution, the company making the distribution remains in the Index, then such company shall remain included in the Index and the stock distribution shall be treated as a dividend from the Index Company based on the closing price of the shares of the spun-off company on its first day of trading. The performance of the shares of the spun-off company shall not thereafter be tracked for purposes of calculating TSR. If, following such stock distribution, the company making the distribution is no longer included in the Index, then such company and the related stock distribution shall not thereafter be tracked for purposes of calculating TSR.

(6)Companies that are added to the Index after the beginning of the applicable Performance Period will not be tracked for purposes of calculating TSR for the Index. Companies that are removed from the Index after the beginning of the applicable Performance Period will nonetheless continue to be considered companies included in the Index for purposes of calculating TSR.

(c)Vesting and Settlement in the Event of a Qualifying Termination. If, prior to the Vesting Date, the Grantee experiences a Qualifying Termination, then provided that the Grantee executes, delivers and does not revoke a Release of Claims, the Attained RSUs shall be determined in accordance with Section 1.2(b) as if the Grantee had continued to be actively

employed by the Company through the Vesting Date. Such Attained RSUs will be settled on the Settlement Date.

(d)Vesting and Settlement in the Event of a Termination of Employment Due to Death or Disability. Notwithstanding any provision in this Agreement to the contrary, if, prior to the Vesting Date, the Grantee’s employment terminates due to his death or Disability, the Target RSUs shall vest and be settled in full within sixty (60) days after the Grantee’s employment terminates, provided, that the Grantee or his executor or estate, as applicable, executes, delivers and does not revoke a Release of Claims. For purposes of vesting under this Section, the Vesting Date shall be the date Grantee’s employment terminates.

(e)Vesting and Settlement in the Event of a Change in Control. Notwithstanding any provision of this Agreement to the contrary, if, prior to the Vesting Date, the Company experiences a Change in Control, the Performance Metrics set forth in subsection (b) will no longer apply to any unvested Target RSUs. Instead, after a Change in Control, the Target RSUs shall vest on the Vesting Date, without regard to the Performance Metrics, as long as the Grantee remains actively employed by the Company on the Vesting Date, or in the event of a Qualifying Termination, Death or Disability, any unvested Target RSUs shall vest as of the date Grantee’s employment terminates and shall be settled in full within sixty (60) days after the Grantee’s employment terminates; provided, that the Grantee or his executor or estate, as applicable, executes, delivers and does not revoke a Release of Claims.

Except as provided in Section 1.2, upon the Grantee’s Termination of Employment, any unvested RSUs shall immediately be forfeited to the Company, and neither the Grantee nor any of the Grantee’s successors, heirs, assigns, or personal representatives shall thereafter have any further rights or interests in such then forfeited RSUs.

The Company agrees to withhold from the settlement of any portion of the Award, the minimum amount required by the federal, state, and local taxes and withholdings the Company determines are required to be withheld under applicable tax laws with respect to the Award (the “Tax Withholding Amount”), and subject to the conditions and restrictions of this Agreement and the Plan. Payment of the Tax Withholding Amount shall be effected by the Company as follows: (i) with respect to Attained RSUs settled in Stock: (x) withholding the number of shares of Stock with an aggregate Fair Market Value equal to the Tax Withholding Amount, (y) selling shares to cover the Tax Withholding Amount on the open market or (z) any combination of these methods; and (ii) with respect to Attained RSUs settled in undeferred cash, the amount paid to the Grantee will be reduced by the Tax Withholding Amount. “Fair Market Value” of an Attained RSU will be calculated based on the closing price of Cowen Inc. stock on March 10, 2025.
