The performance-based requirement will be satisfied if an Issuer stock price target is satisfied during the trailing consecutive twenty trading day period ending on the most recent trading day prior to the Beginning Measurement Date or, thereafter during any trailing consecutive twenty trading day period beginning on the Beginning Measurement Date through the applicable measurement date.
