Pursuant to Section 9.1 of the EVO Payments, Inc. 2018 Omnibus Incentive Stock Plan (the “Plan”), the Company hereby grants to the Grantee an Award for a target number of              Performance Units (the “Target Award”); provided that the number of Performance Units that the Grantee actually earns for the Performance Period will be determined by the level of achievement of performance goals specified by the Committee (the “Performance Goals”), as set forth on Exhibit A. Capitalized terms that are used but not defined herein have the meaning ascribed to them in the Plan.

2.    Consideration. The grant of the Performance Units is made in consideration of the services to be rendered by the Grantee to the Company or its affiliates.

3.    Performance Period.

3.1    The Performance Period shall be the period commencing on [DATE] and ending on [DATE].

3.2    The number of Performance Units actually earned by the Grantee (the “Earned Performance Units”) will be determined at the end of the Performance Period based on the level of achievement of the Performance Goals in accordance with Exhibit A.

3.3    Promptly following completion of the Performance Period (and no later than [thirty (30) days] following the end of the Performance Period), the Committee will review and certify in writing (a) whether, and to what extent, the Performance Goals for the Performance Period have been achieved, and (b) the number of Earned Performance Units, if any.

4.    Vesting.

4.1    The Performance Units are subject to forfeiture until they vest. Except as otherwise provided herein, the Performance Units will vest and become nonforfeitable on the last day of the Performance Period, subject to (a) the achievement of the minimum threshold Performance Goals for payout set forth in Exhibit A attached hereto, and (b) the Grantee has not incurred a Termination of Service as of the last day of the Performance Period. The number of

Performance Units that vest and become payable under this Agreement shall be determined by the Committee based on the level of achievement of the Performance Goals set forth in Exhibit A.

4.2        If the Grantee incurs a Termination of Service as the result of death or Disability, the Grantee will become vested in the number of Performance Units (rounded up to the nearest whole unit) that would have become vested as of the anniversary of the Grant Date next following such Grantee’s death or Disability.

To the extent Shares are issued, such Shares may be granted subject to any restrictions that may be imposed by the Committee, including a Period of Restriction or mandatory deferral.

7.    Rights as Shareholder. The Grantee shall not have any rights of a stockholder with respect to the Performance Units (including, without limitation, any voting rights or any right to dividends paid with respect to the Shares underlying such Performance Units).

8.    No Right to Continued Service. Neither the Plan nor this Agreement shall confer upon the Grantee any right to be retained in any position, as an Employee, consultant, advisor or Nonemployee Director of the Company.

EXHIBIT A

PERFORMANCE GOALS

The performance measures for this grant of Performance Units shall be: [A], [B], and [C], each, a “Performance Measure”)¹. The percentage earned for attaining threshold, target and maximum performance levels for each Performance Measure is shown on the following table:

Straight line interpolation will be used between each of the performance levels shown on the table above. No amount will be earned with respect to a Performance Measure if the performance is below the threshold level. A maximum of 200% will be earned with respect to a Performance Measure regardless of performance in excess of the maximum level.

To determine a Grantee’s Earned Performance Units, the “Payout % of Target Award” for each Performance Measure will be multiplied by the weighting percentage for that Performance Measure. The sum of these percentages will then be multiplied by the Grantee’s Target Award to determine a Grantee’s Earned Performance Units. The maximum Shares that may be earned under this Performance Unit Award is [200%]⁵ of the Grantee’s Target Award.

¹ Select one or more Performance Measures from Section 12.1 of the Plan.

² Determine the weighting applicable to each Performance Measure.

³ Determine the threshold and maximum performance levels.

⁴ Determine the level of payout for the threshold and maximum performance levels

⁵ Confirm maximum payout level.
