        <footnote id="F1">Common stock and derivative securities were acquired pursuant to the merger agreement dated February 22, 2014, as amended on July 15, 2014, by and among RF Micro Devices, Inc. (&quot;RFMD&quot;), TriQuint Semiconductor, Inc., and Qorvo, Inc. (&quot;Qorvo&quot;).

Also pursuant to the merger agreement, upon the closing of the merger on January 1, 2015, all RFMD equity awards were assumed by Qorvo, with such equity awards to be exercisable for or able to be settled in shares of Qorvo common stock, based on the exchange ratio of 0.25.</footnote>
