2.Retention Award Subject to Clawback.

Where applicable under local law, if prior to the one-year anniversary of the Payment Date, you voluntarily resign or the Company terminates your employment for Cause, then you must repay the entire after-tax value of your Retention Award to the Company within 30 days following your resignation or the “for Cause” termination of your employment. You are not entitled to a pro-rated Retention Award based upon the date your employment terminates for Cause or your voluntary resignation. This is a full recourse obligation to you, meaning that you are personally liable for any repayment obligation under this letter and the Company may take any collection actions it deems necessary.
