        <footnote id="F1">The two reported transactions involve an amendment of an outstanding option to extend the expiration date of such option from October 17, 2018 to October 17, 2023, resulting in the deemed cancellation of the &quot;old&quot; option and the grant of a replacement option. The option was originally granted on October 17, 2013 and provided for vesting (i) with respect to 25% of the underlying shares on the anniversary of the original date of grant and (ii) with respect to the remaining underlying shares, ratably each anniversary thereafter until fully vested on the fourth anniversary of the original date of grant.</footnote>
