Effective March 28, 2023, CSGS adopted and now maintains the CSG Systems International, Inc. Executive Severance Plan, a copy of which is attached hereto as Exhibit A (the “2023 Plan”).

The parties are entering into this Agreement in connection with the adoption of the 2023 Plan.

In lieu of 200% of base salary and 200% of annual performance bonus provided in Section 5.1 of the 2023 Plan for an Eligible Termination occurring within 18 months after a Change in Control, to match the amount payable in this situation under the Employment Agreement, an amount equal to 300% of base salary and 300% of annual performance bonus will be payable to Executive for an Eligible Termination occurring within 18 months after a Change in Control.
