For additional information, please consult the Change of Control Plan. Notwithstanding the terms of the Change of Control Plan, any payments to be made to you under the Change of Control Plan shall be offset and reduced by any termination entitlements owed to you by Vertiv or any affiliate of Vertiv, including, without limitation, remuneration paid to you during any period of notice, and any Statutory Severance that Vertiv or any affiliate of Vertiv is required to pay to you, to the extent that Statutory Severance benefits are not waived or are not waivable.
