On October 14, 2013, Intersil Corporation (the “Company”) entered into a Change in Control Severance Agreement (the “Agreement”) with Roger Wendelken, its newly-appointed Sr. Vice President of Worldwide Sales.  The Agreement provides that in the event Mr. Wendelken’s employment is terminated for certain reasons following a change in control of the Company, Mr. Wendelken would be eligible to receive, subject to his execution of a release, (i) his targeted cash bonus, prorated through the date of termination, (ii) a lump sum payment equal to one hundred percent (100%) of the sum of his annual base salary (at the rate in effect at the time of termination or the time of the change in control, whichever is higher) and target annual bonus for the year of termination, (iii) continued participation in the Company’s medical plan and other welfare benefit plans (on the same terms and conditions as were in effect at the date of termination, including provisions regarding the cost of such participation to Mr. Wendelken) for one year and reimbursements for any taxes incurred by him in connection with the receipt of such medical and welfare benefits, and (iv) full accelerated vesting of all of his stock options and restricted stock awards. In the case of performance-based stock awards, such awards would fully vest at a value determinable at the time of the change in control. Under the Agreement, a change in control would generally occur when (i) the Company’s shareholders approve certain mergers, liquidations or a sale of substantially all of the Company’s assets, (ii) any person or entity acquires 25% or more of the  Company’s voting securities, or (iii) a majority of the Company’s directors are replaced during a three-year period.

The preceding description of the Agreement is a summary only and is qualified in its entirety by reference to the Agreement, a copy of which is filed as an exhibit hereto.
