Provided, however, that if the company terminates your employment involuntarily for reasons other than cause, you will receive the full retention payment within thirty days of your termination effective date. If there is a change in control prior to the third anniversary, you will be owed a pro-rated calculation of the retention for your days of active employment upon the event for any remaining amount owed.
