On April 3, 2013, the Board of Directors of Semtech Corporation (the “Company”), based upon the recommendation of the Board’s Nominating and Governance Committee, expanded the size of the Board from eight to ten and appointed Dr. Carmelo Santoro and Ms. Sylvia Summers as directors to fill the vacancies created by such expansion.  Neither Dr. Santoro nor Ms. Summers have been named to any committees of the Board at this time.

Like the other non-employee members of the Board, Dr. Santoro and Ms. Summers will each receive an annual retainer of $45,000 for their service (prorated to reflect their service dates in 2013).  Each of Dr. Santoro and Ms. Summers will receive any additional compensation, including annual equity awards, consistent with that received by the Company’s other non-employee directors under the Company’s Policy Regarding Director Compensation, the terms of which are described in the Company’s Proxy Statement for Annual Meeting of Stockholders held June 21, 2012 under the caption “Director Compensation — Director Compensation Policy.” Consistent with such Policy, upon appointment as new Board members Dr. Santoro and Ms. Summers were each granted 20,000 options to purchase Company common stock at an exercise price of $33.22 per share.

Ms. Summers has extensive experience in engineering, business development and leadership, including serving as the Chief Executive Officer and President of Trident Microsystems from 2007 to 2011. Prior to that experience, she held senior positions at Spansion LTD, Cisco Systems, Inc. and Storagetek. Ms. Summers currently serves on the Board of Directors for Headwaters, Inc., a public company providing product, technology and services to the heavy construction materials, light building products, and energy industries. She holds a B.S. in Electrical Engineering from Ecole Polytechnique Feminine in Paris, France, an M.S. in Electrical Engineering from the University of California, Berkeley, and an M.B.A. from Thomson CSF, France.
