Each Severance Agreement provides that, subject to the Company receiving a general release of claims from the executive in the form attached as Appendix II to the Severance Agreement, in the event the executive’s employment is terminated (i) by the Company without “Cause” during a “Pending Change in Control” (as such terms are defined in the Severance Agreement) or within 12 months following a “Change in Control” (as defined in the Severance Agreement) or (ii) by the executive for “Good Reason” (as defined in the Severance Agreement) within 12 months following a Change in Control, the executive will be entitled to receive an amount in cash equal to two times the sum of (a) the executive’s annual base salary and (b) the amount of the executive’s annual target bonus for the year in which the executive was terminated assuming the achievement of 100% of the performance target levels associated with such annual target bonus. In addition, the unvested portions of all of the executive’s time-vest restricted stock units then outstanding will immediately vest, in full, as of the date of such executive’s termination.

The foregoing is a summary only and does not purport to be a complete description of all of the terms, provisions, covenants, and agreements contained in the Severance Agreements, and is subject to and qualified in its entirety by reference to the complete text of the Severance Agreements, a copy of the form of which is filed herewith as Exhibit 10.16 and incorporated herein by reference.
