Effective February 28, 2013, the Company entered into an Executive Change in Control Severance Agreement (the “Severance Agreement”) with Todd B. Schull, the Company’s Executive Vice President, Chief Financial Officer, Treasurer and Secretary. The Severance Agreement provides that, subject to the Company receiving a general release of claims from Mr. Schull in the form attached as Appendix II to the Severance Agreement, in the event Mr. Schull’s employment is terminated by (i) 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 Mr. Schull for “good reason” (as defined in the Severance Agreement) within 12 months following a change in control, Mr. Schull would be entitled to receive an amount in cash equal to two times the sum of (a) Mr. Schull’s annual base salary and (b) the amount of Mr. Schull’s annual target bonus for the year in which Mr. Schull was terminated assuming the achievement of 100% of the performance target levels associated with such annual target bonus; in addition, the vesting of any of Mr. Schull’s stock options, restricted stock, and restricted stock units assumed by the surviving entity in connection with a change in control would be accelerated.

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 Agreement, and is subject to and qualified in its entirety by reference to the complete text of the Severance Agreement, which is incorporated herein by reference to Exhibit 10.17 filed with the Current Report on Form 8-K filed by the Company on January 19, 2012.
